                     NL INDUSTRIES, INC. AND SUBSIDIARIES

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - ORGANIZATION AND BASIS OF PRESENTATION:

      NL  Industries,  Inc.  conducts its  titanium  dioxide  pigments  ("TiO2")
operations through its wholly-owned subsidiary, Kronos, Inc. In January 1998 the
specialty  chemicals business of Rheox,  Inc., a wholly-owned  subsidiary of NL,
was sold.  At  September  30, 1998 Valhi,  Inc.  and Tremont  Corporation,  each
affiliates of Contran Corporation, held approximately 58% and 19%, respectively,
of NL's  outstanding  common stock, and together may be deemed to control NL. At
September  30,  1998  Contran and its  subsidiaries  held  approximately  92% of
Valhi's outstanding common stock, and Valhi and other entities related to Harold
C. Simmons held approximately 53% of Tremont's outstanding common stock.

      The  consolidated  balance sheet of NL Industries,  Inc. and  Subsidiaries
(collectively,  the  "Company") at December 31, 1997 has been condensed from the
Company's  audited   consolidated   financial   statements  at  that  date.  The
consolidated balance sheet at September 30, 1998 and the consolidated statements
of income,  comprehensive  income,  shareholders'  equity and cash flows for the
interim  periods  ended  September  30, 1997 and 1998 have been  prepared by the
Company,  without  audit.  In  the  opinion  of  management,   all  adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
consolidated financial position,  results of operations and cash flows have been
made.  The results of  operations  for the interim  periods are not  necessarily
indicative of the operating results for a full year or of future operations.

      Certain  information  and  footnote   disclosures   normally  included  in
financial  statements  prepared in accordance with generally accepted accounting
principles have been condensed or omitted.  Certain prior-year amounts have been
reclassified to conform to the current year  presentation,  including  reporting
the Company's  specialty  chemicals  business as a discontinued  operation.  The
accompanying  consolidated  financial  statements  should be read in conjunction
with the  consolidated  financial  statements  included in the Company's  Annual
Report on Form 10-K for the year  ended  December  31,  1997 (the  "1997  Annual
Report").

      The  Company  will  adopt  Statement  of  Financial  Accounting  Standards
("SFAS") No. 133, Accounting for Derivative  Instruments and Hedging Activities,
no later than the first  quarter of 2000.  SFAS No. 133  establishes  accounting
standards for derivative  instruments,  including certain derivative instruments
embedded in other contracts, and for hedging activities. Under SFAS No. 133, all
derivatives  will be recognized as either assets or liabilities  and measured at
fair value.  The accounting for changes in fair value of derivatives will depend
upon the intended use of the derivative.  The Company is currently studying this
newly-issued  accounting  rule, and the impact of adopting SFAS No. 133, if any,
has not yet been  determined  but will be dependent upon the extent to which the
Company  is  then  a  party  to  derivative  contracts  or  engaged  in  hedging
activities.  At September 30, 1998 the Company is not a party to any  derivative
contracts or engaged in any hedging activities covered by SFAS No. 133.

NOTE 2 - EARNINGS PER SHARE:

      Basic  earnings  per  share are based on the  weighted  average  number of
common shares  outstanding  during each period.  Diluted  earnings per share are
based on the weighted average common shares  outstanding and the dilutive impact
of outstanding stock options.

NOTE 3 - BUSINESS SEGMENT INFORMATION:

      The  Company's  continuing  operations  are  conducted  by  Kronos  in one
business segment - TiO2.

NOTE 13 - DISCONTINUED OPERATIONS:

      The Company sold the net assets of its Rheox specialty  chemicals business
for $465 million cash (before fees and  expenses) in the first  quarter of 1998,
including $20 million  attributable to a five-year  agreement by the Company not
to compete in the  rheological  products  business.  The Company  recognized  an
after-tax  gain of  approximately  $286  million  on the  sale of this  business
segment.  A portion of the $380  million  after-tax  proceeds was used to reduce
outstanding indebtedness by approximately $231 million.

      In July 1998 the Company reached an agreement (the "Tioxide  Purchase") to
(i) acquire the North American TiO2 operations of Imperial  Chemical  Industries
plc's ("ICI")  subsidiary,  Tioxide Group  Limited,  and a Tioxide TiO2 plant in
England, and (ii) cancel certain rights to chloride-process  technology licensed
to Tioxide by the Company in connection with the formation of Louisiana  Pigment
Company ("LPC") in 1993. The aggregate amount to be paid to ICI is approximately
$365  million,  including a $30 million fee for the  cancellation  of technology
rights and approximately $50 million in working capital. The purchase is subject
to regulatory clearances,  completion of the purchase by E.I. du Pont de Nemours
&  Co.  of  ICI's  remaining  non-North  American  TiO2  business  (the  "DuPont
Purchase"), and other conditions customary to transactions of this type.

      The operations to be acquired  include  Tioxide's  50%-interest  in LPC, a
manufacturing  joint  venture  of  the  Company  and  Tioxide  that  operates  a
chloride-process  TiO2 plant in Louisiana with capacity of approximately 120,000
metric tons per annum ("mtpa"); Tioxide's 75,000 mtpa sulfate-process TiO2 plant
in Grimsby, England; Tioxide's 52,000 mtpa finishing plant in Tracy, Quebec; and
Tioxide's North American marketing and distribution business.

      Upon  completion  of the DuPont  Purchase  and the Tioxide  Purchase,  the
Company  expects to become  the  world's  third  largest  manufacturer  of TiO2,
increasing its productive capacity by approximately 135,000 mtpa.

      Assuming  regulatory  clearances are received in 1998, the Company expects
the Tioxide Purchase to close in the first quarter of 1999.

</TABLE>

      Kronos'  operating  income in the third  quarter  and first nine months of
1998 increased from the comparable periods in 1997 due to higher average selling
prices,  partially  offset by lower sales volume and the absence of $9.7 million
of income from refunds of German  franchise  taxes received in the third quarter
of 1997. Kronos expects its fourth-quarter 1998 operating income will exceed its
fourth-quarter  1997  operating  income  primarily  because  of  higher  average
fourth-quarter  1998 TiO2 selling prices,  partially  offset by moderately lower
fourth-quarter 1998 sales volume.

      Average TiO2 selling  prices for the third quarter of 1998 were 17% higher
than the third quarter of 1997 and 2% higher than the second quarter of 1998.

      Kronos'  third-quarter  sales  volume  decreased  9% from the record sales
volume in the year-earlier period as demand moderated. Sales volume in the first
nine  months  of 1998  was 2%  lower  than  the  year-earlier  period  primarily
reflecting  lower sales volume in Asia,  partially offset by higher sales volume
in  Europe.  As a result of lower  second-half  1998  demand  for  TiO2,  Kronos
anticipates its TiO2 sales volume for full-year 1998 will be slightly below that
of calendar year 1997.

      Kronos' cost of sales as a percentage of net sales  decreased in the third
quarter and first nine months of 1998  primarily due to higher  average  selling
prices.  Kronos' selling,  general and administrative  expenses decreased in the
third  quarter  and first nine  months of 1998 due to lower  distribution  costs
associated  with lower sales volume and  favorable  effects of foreign  currency
translation,  partially offset by the impact of the German franchise tax refunds
received in the third quarter of 1997.

      A significant amount of sales are denominated in currencies other than the
U.S. dollar,  and fluctuations in the value of the U.S. dollar relative to other
currencies  decreased  the dollar value of sales for the third quarter and first
nine months of 1998 by $3 million and $26 million, respectively, compared to the
comparable 1997 periods.

</TABLE>

      Securities earnings increased due to higher average balances available for
investment.  Corporate expenses,  net in the first nine months of 1998 was lower
than the comparable  period in 1997 due to the $30 million  noncash charge taken
in the first quarter of 1997 related to the Company's  adoption of SOP No. 96-1,
"Environmental  Remediation  Liabilities."  This  charge is included in selling,
general and administrative expense in the Company's  consolidated  statements of
income.

      The Company expects general corporate interest income and interest expense
to be lower in the fourth  quarter of 1998 compared to the third quarter of 1998
due to the  redemption  of the remaining 13% Senior  Secured  Discount  Notes on
October 15, 1998.

      Income  taxes in the third  quarter of 1998  include a tax benefit of $8.2
million resulting from a refund of prior-year German dividend withholding taxes.

      The Company sold the net assets of its Rheox specialty  chemicals business
in the first quarter of 1998 and, as a result of the sale,  Rheox's  results are
reported as discontinued operations.

and payables  (excluding  the effect of currency  translation)  used cash in the
first nine  months of 1998 but  provided  cash in the first nine  months of 1997
primarily due to  reductions  in inventory  levels in the 1997 period and higher
payments  of income  taxes in the 1998 period as a result of the gain on sale of
Rheox.

      The  sale of the  Company's  specialty  chemicals  business  in the  first
quarter of 1998 resulted in net proceeds of $380 million  after  current  income
taxes and other  expenses.  In the first nine months of 1998, the Company used a
portion of the net proceeds to repay certain  indebtedness,  as described below,
and on  October  15,  1998,  used a portion  of the net  proceeds  to redeem the
remaining  $119 million of 13% Senior  Secured  Discount Notes at the redemption
price of 106% of the  principal  amount,  in  accordance  with the  terms of the
Discount Notes indenture.

      During the first nine months of 1998,  the  Company  used a portion of the
net  proceeds  to (i) prepay $118  million of the Rheox  credit  facility,  (ii)
prepay $42 million of Kronos'  share of the LPC joint  venture term loan,  (iii)
make $65 million of  open-market  purchases of the Company's 13% Senior  Secured
Discount  Notes at prices  ranging  from  $101.25 to  $105.19  per $100 of their
principal amounts,  and (iv) purchase $6 million of the Senior Secured Notes and
$61 thousand of the Senior Secured  Discount Notes at a price of $100 and $96.03
per $100 of their principal amounts,  respectively,  pursuant to a June 1998 pro
rata tender offer to Note holders as required under the terms of the indenture.

      The Company  prepaid DM 81 million  ($44 million when paid) of its DM term
loan in the first quarter of 1998. A portion of the funds for such prepayment of
the DM term loan was provided by a first-quarter DM 35 million ($19 million when
borrowed)  increase in  outstanding  borrowings  under the Company's  short-term
non-U.S. credit facilities. In the second quarter of 1998, the Company repaid DM
20 million ($11 million when paid) of the DM revolving credit facility.

      In order to complete the Tioxide  Purchase,  the Company expects to borrow
approximately $250 million in bank financing.

      At  September  30,  1998  the  Company  had  cash  and  cash   equivalents
aggregating  $321  million  (14%  held  by  non-U.S.  subsidiaries),   including
restricted cash equivalents of $13 million.  The Company's  subsidiaries had $91
million  available for borrowing at September 30, 1998 under  existing  non-U.S.
credit facilities.

      In the  third  quarter  of 1998,  the  Company  paid a  regular  quarterly
dividend of $.03 per share to shareholders  aggregating $1.5 million.  Dividends
paid during the first nine months of 1998 totaled $3.1 million.  In October 1998
the Company's Board of Directors  declared a regular quarterly  dividend of $.03
per  share to  shareholders  of  record as of  December  16,  1998 to be paid on
December 30, 1998.

      In June 1998, as a result of the  settlement  of a shareholder  derivative
lawsuit on behalf of the Company, Valhi transferred $14.4 million in cash to the

                                   - 20 -

Company, and the Company agreed to pay plaintiffs'  attorneys' fees and expenses
of $3.2 million.

      Certain  of the  Company's  tax  returns  in  various  U.S.  and  non-U.S.
jurisdictions  are being  examined  and tax  authorities  have  proposed  or may
propose tax deficiencies,  including  non-income tax related items and interest.
The Company  previously reached an agreement with the German tax authorities and
paid certain tax  deficiencies of  approximately DM 44 million ($28 million when
paid),  including  interest,  which resolved  significant tax  contingencies for
years through 1990. In the third quarter of 1998,  the Company  received a DM 14
million ($8.2 million when received) refund of 1990 German dividend  withholding
taxes.  The German tax authorities were required to refund such amounts based on
a recent German Supreme Court decision in favor of another taxpayer.  The refund
resulted in a reduction of the settlement  amount from DM 44 million referred to
above to DM 30  million  for years  through  1990.  No further  withholding  tax
refunds are expected.

      Certain  other  significant   German  tax  contingencies   aggregating  an
estimated  DM 172 million  ($102  million at September  30,  1998)  through 1997
remain outstanding and are in litigation. Of these, one primary issue represents
disputed amounts  aggregating DM 160 million ($95 million at September 30, 1998)
for  years  through  1997.  The  Company  has  received  tax  assessments  for a
substantial   portion  of  these  amounts.   No  payments  of  tax  or  interest
deficiencies  related to these  assessments are expected until the litigation is
resolved.  During  1997 a German  tax  court  proceeding  involving  a tax issue
substantially  the same as this issue was decided in favor of the taxpayer.  The
German tax authorities  have appealed that decision to the German Supreme Court.
The  Company  believes  that a  decision  by the  German  Supreme  Court will be
rendered  within a year and will likely  determine  the outcome of the Company's
primary dispute with the German tax  authorities.  Although the Company believes
that it will ultimately  prevail in this matter, the Company has granted a DM 94
million ($56 million at September 30, 1998) lien on its Nordenham,  Germany TiO2
plant in favor of the City of  Leverkusen,  and a DM 5 million  ($3  million  at
September 30, 1998) lien in favor of the German federal tax authorities.  If the
Company does not prevail,  these  contingencies  will increase the Company's tax
liability  for 1990 and each year  thereafter,  and the  Company  would  seek to
negotiate payment over a period of time.

      In addition,  during 1997 the Company reached an agreement with the German
tax authorities  regarding  certain other issues not in litigation for the years
1991 through 1994, and agreed to pay additional tax deficiencies of DM 9 million
($5 million at September 30, 1998),  most of which was paid in the third quarter
of 1998.

      During 1997 the Company  received a tax assessment  from the Norwegian tax
authorities  proposing  tax  deficiencies  of  NOK 51  million  ($7  million  at
September 30, 1998) relating to 1994.  The Company has appealed this  assessment
and has begun litigation proceedings. Although the Company believes that it will
ultimately  prevail,  the  Company has granted a lien for the full amount of the
tax assessment on its  Fredrikstad,  Norway TiO2 plant in favor of the Norwegian
tax authorities.

      No  assurance  can be given that these tax matters will be resolved in the
Company's  favor  in  view  of the  inherent  uncertainties  involved  in  court
proceedings.  The Company  believes that it has provided  adequate  accruals for
additional taxes and related  interest expense which may ultimately  result from
all such  examinations  and  believes  that  the  ultimate  disposition  of such
examinations  should  not  have a  material  adverse  effect  on  the  Company's
consolidated financial position, results of operations or liquidity.

      The Company has been named as a defendant,  potentially  responsible party
("PRP"), or both, in a number of legal proceedings associated with environmental
matters,  including  waste  disposal  sites,  mining  locations  and  facilities
currently or previously owned, operated or used by the Company, certain of which
are on the U.S.  Environmental  Protection  Agency's (the "U.S.  EPA") Superfund
National  Priorities  List or similar  state lists.  On a quarterly  basis,  the
Company  evaluates  the  potential  range of its liability at sites where it has
been named as a PRP or defendant.  The Company believes it has adequate accruals
($128  million at September  30, 1998) for  reasonably  estimable  costs of such
matters,  but the  Company's  ultimate  liability may be affected by a number of
factors,   including  changes  in  remedial  alternatives  and  costs,  and  the
allocations  of such costs among PRPs.  It is not possible to estimate the range
of costs for certain  sites.  The upper end of the range of reasonably  possible
costs to the Company  for sites for which it is  possible  to estimate  costs is
approximately $160 million. The Company's estimates of such liabilities have not
been  discounted  to present  value,  and the  Company  has not  recognized  any
potential insurance recoveries. No assurance can be given that actual costs will
not  exceed  accrued  amounts  or the upper end of the range for sites for which
estimates  have been made,  and no assurance can be given that costs will not be
incurred  with respect to sites as to which no estimate  presently  can be made.
Further,  there can be no assurance that additional  environmental  matters will
not arise in the future.

      The Company is also a defendant in a number of legal  proceedings  seeking
damages for personal  injury and property  damage  arising from the sale of lead
pigments and lead-based paints.  There is no assurance that the Company will not
incur  future  liability in respect of this  pending  litigation  in view of the
inherent  uncertainties  involved  in court  and jury  rulings  in  pending  and
possible  future cases.  However,  based on, among other things,  the results of
such litigation to date, the Company  believes that the pending lead pigment and
paint  litigation is without merit.  The Company has not accrued any amounts for
such pending litigation. Liability that may result, if any, cannot be reasonably
estimated. In addition, various legislation and administrative regulations have,
from  time to time,  been  enacted  or  proposed  that  seek to  impose  various
obligations on present and former  manufacturers  of lead pigment and lead-based
paint with respect to asserted health  concerns  associated with the use of such
products and to effectively  overturn  court  decisions in which the Company and
other  pigment  manufacturers  have been  successful.  Examples of such proposed
legislation  include bills which would permit civil liability for damages on the
basis of market  share,  rather  than  requiring  plaintiffs  to prove  that the
defendant's  product caused the alleged damage.  The Company currently  believes
the disposition of all claims and disputes,  individually  and in the aggregate,
should  not  have  a  material  adverse  effect  on the  Company's  consolidated
financial

                                   - 22 -

<PAGE>



position,  results of operations or  liquidity.  There can be no assurance  that
additional matters of these types will not arise in the future.

      The Company is in the process of  evaluating  and  upgrading  its computer
systems (both information technology ("IT") systems and non-IT systems involving
embedded chip technology) and software applications (collectively referred to as
"systems") to ensure that the systems  function  properly  beginning  January 1,
2000.  To achieve  its year 2000  compliance  plan,  the  Company  is  utilizing
internal and external resources to identify,  correct or reprogram, and test its
systems.

      The Company has conducted an inventory of its IT systems  worldwide and is
currently  testing the  systems and  applications  that have been  corrected  or
reprogrammed for year 2000  compliance.  The Company has completed a preliminary
inventory  of its  non-IT  systems  and  is in the  process  of  validating  the
inventory and correcting or replacing date-deficient systems. The Company uses a
number of  packaged  software  products  that have been  upgraded to a year 2000
compliant version in the normal course of business.  Excluding the cost of these
software  upgrades,  the  Company's  cost of  becoming  year 2000  compliant  is
expected to be approximately $2 million, of which about one-third has been spent
through September 1998. The Company expects its major IT systems to be year 2000
compliant  by March  1999,  and  expects  its  non-IT  systems  to be year  2000
compliant by September 1999.

      As part of its year  2000  compliance  plan,  the  Company  has  requested
confirmations  from its major domestic and foreign  software  vendors,  hardware
vendors and primary  suppliers,  that they are developing and implementing plans
to become, or are, year 2000 compliant.  Confirmations received to date from the
Company's software vendors, hardware vendors and primary suppliers indicate that
generally they are in the process of  implementing  remediation  plans to ensure
that their  systems are  compliant  by December  31,  1999.  The major  software
vendors used by the Company have already delivered year 2000 compliant software.
The Company plans to request  confirmations  from its major  customers that they
are developing or implementing plans to become year-2000 compliant.

      The Company is developing a  contingency  plan to address  potential  year
2000  related  business  interruptions  that may occur on January  1,  2000,  or
thereafter. This plan is expected to be completed in the second quarter of 1999.

      Although the Company expects its systems to be year 2000 compliant  before
December  31,  1999,  it cannot  predict the outcome or success of the year 2000
compliance programs of its vendors,  suppliers,  and customers. The Company also
cannot predict whether its major software vendors, who continue to test for year
2000  compliance,  will find additional  problems that would result in unplanned
upgrades of their  applications  after  December 31, 1999.  As a result of these
uncertainties,  the Company cannot predict the impact on its financial condition
or results of  noncompliant  year 2000  systems  that the  Company  directly  or
indirectly  relies upon.  Should the Company's year 2000  compliance plan not be
successful or be delayed beyond January 2000,  the  consequences  to the Company
could be  far-reaching  and material,  including an inability to produce TiO2 at
its  manufacturing  facilities,  which could lead to an indeterminate  amount of
lost

                                   - 23 -

<PAGE>



revenue.  Other potential negative consequences could include plant malfunction,
impeded  communications or power supplies, or slower transaction  processing and
financial reporting.

      Beginning  January 1, 1999,  eleven of the fifteen members of the European
Union ("EU"),  including  Germany,  Belgium,  the Netherlands  and France,  have
agreed to adopt a new European  currency unit (the "euro") as their common legal
currency.  Following the introduction of the euro, the participating  countries'
national  currencies will remain legal tender as  denominations of the euro from
January 1, 1999 through January 1, 2002, and the exchange rates between the euro
and such national currency units will be fixed.

      The Company  conducts  substantial  operations in Europe.  The  functional
currency of the Company's  German,  Belgian,  Dutch and French  operations  will
convert to the euro from their  respective  national  currencies over a two-year
period  beginning  in  1999.  The  euro  conversion  may  impact  the  Company's
operations including,  among other things,  changes in product pricing decisions
necessitated  by  cross-border  price  transparencies.  Such  changes in product
pricing  decisions  could impact both selling prices and  purchasing  costs and,
consequently, favorably or unfavorably impact results of operations.

      The  Company  has  a  significant  amount  of  outstanding  DM-denominated
indebtedness  and such debt will become  euro-denominated  effective  January 1,
1999.   Modifications   of  information   systems  to  handle   euro-denominated
transactions will be required, although the modifications are not expected to be
extensive.

      The Company has begun to assess and evaluate  the  expected  impact of the
euro conversion on its business.  Such  evaluations are still in process but are
expected to be  concluded by the end of 1998.  The Company  expects to spend and
charge to expense  less than $1  million in  evaluation  and  conversion  costs.
Because  of  the  inherent  uncertainty  of the  ultimate  affect  of  the  euro
conversion,  the Company cannot accurately  predict the impact on its results of
operations, financial condition or liquidity.

      The Company periodically evaluates its liquidity requirements, alternative
uses of capital,  capital needs and  availability of resources in view of, among
other  things,  its  debt  service  and  capital  expenditure  requirements  and
estimated future operating cash flows. As a result of this process,  the Company
in the past has  sought,  and in the  future  may seek,  to  reduce,  refinance,
repurchase  or  restructure   indebtedness,   raise  additional  capital,  issue
additional  securities,   modify  its  dividend  policy,  restructure  ownership
interests, sell interests in subsidiaries or other assets, or take a combination
of such steps or other steps to manage its liquidity and capital  resources.  In
the normal course of its business,  the Company may review opportunities for the
acquisition,  divestiture,  joint venture or other business  combinations in the
chemicals   industry.   In  the  event  of  any  acquisition  or  joint  venture
transaction,  the Company may consider  using  available  cash,  issuing  equity
securities  or  increasing  its  indebtedness  to the  extent  permitted  by the
agreements governing the Company's existing debt.

<PAGE>


          THIS AGREEMENT (the "AGREEMENT") is made on 24 July 1998 between:


          (1) IMPERIAL CHEMICAL INDUSTRIES PLC, a company incorporated under the
              laws of England,  whose registered  office is at Imperial Chemical

                      received or given in connection  with any  proceeding by a
                      private party,  in each case regarding any of the Proposed
                      Transactions,  and  permit  any other  party to review any
                      material communication given by or to it; and

                  (iii) consult  with each  other,  in advance of any meeting or
                      conference  with  such  governmental  authorities  or,  in
                      connection  with any proceeding by a private  party,  with
                      any other person  provided that in relation to unsolicited
                      communications,  the obligations in this sub-Clause  shall
                      be such as are practicable in the relevant circumstances.

          2.3.3   The  parties  will  use  all  reasonable  endeavours to obtain
                  such  approvals  as promptly as possible  and, in this regard,
                  provide all information reasonably requested, shall assist and
                  co-operate with one another to make the necessary  filings and
                  take  such  other  steps  as  may be  commercially  reasonably
                  required to secure the non-objection of the relevant antitrust
                  and  regulatory  authorities,  provided  that  nothing in this
                  sub-Clause  2.3.3 shall be  construed  to require any party to
                  conduct  its  commercial  affairs  in a manner  other  than in
                  accordance with its own independent business judgement.

          2.3.4   The parties will use all reasonable efforts to take all action
                  and to do all things necessary in order to consummate and make
                  effective  the  transactions  contemplated  by this  agreement
                  (including  satisfaction,  but not waiver,  of all  Conditions
                  Precedent).
<PAGE>


     2.4  The Conditions  Precedent  shall be deemed to have been fulfilled when
          they have been satisfied within the terms described in Schedule 1.

     2.5  Each  party  shall  promptly  advise the  others  once the  Conditions
          Precedent  which  relate to that party have been  fulfilled.  The date
          that  the  last of the  Conditions  Precedent  (other  than  Condition
          Precedent  number 12 relating  to the TEL Sale) has been so  fulfilled
          shall be the "Record Date" and the Completion Date shall be determined
          in accordance with the provisions of sub-Clause 2.7 below. The parties
          shall be deemed to have satisfied or waived any  Conditions  Precedent
          (as  applicable)  by signing and  completing  the Sale  Agreements  in
          accordance with sub-Clause 2.7 below.

     2.6  If the Conditions  Precedent (other than Condition Precedent number 12
          relating  to the TEL Sale)  have not been  fulfilled  by the  Longstop
          Date,  or earlier upon the written  agreement of the parties that such
          Conditions  Precedent  cannot so be met, any of the parties shall have
          the right (but not the  obligation)  to  terminate  this  agreement by
          notice in writing,  to be given after the Longstop  Date or earlier by
          written  agreement  between the parties,  in which case no party shall
          have any rights or  obligations  under  this  agreement  except  under
          Clauses 14, 15, 19, 25 and 26 which shall survive the  termination  of
          this agreement.

     2.7  The TEL Sale shall be  completed  at midnight  London time on the last
          day of the  calendar  month  (or if that last day is a Friday or not a
          Business Day on the first Business Day thereafter) following the month
          in which the Record Date falls.  The date and time of signature and of
          completion  of the Hivedown  Agreement and any documents to be entered
          into pursuant  thereto will be  immediately  thereafter.  The date and
          time of  signature  and  completion  (the  "Completion  Date"  for the
          purposes  of this  agreement)  of the other  Sale  Agreements  will be
          immediately following completion of the Hivedown Agreement as referred
          to above.

     2.8  The parties agree that:

          (a)     the signature and completion of the Sale  Agreements  will not
                  take place unless  completion of the TEL Sale has taken place;
                  and

          (b)     the signature  and  completion of each of the Newco Share Sale
                  Agreement and each of the Americas Share Sale  Agreements will
                  be  simultaneous  and none will be  completed  unless  all are
                  completed.

     2.9  Immediately  after the TEL  Completion  Date but before  the  Hivedown
          Agreement is entered into,  the Purchaser  shall serve written  notice
          upon  DuPont and TEL and DuPont  shall  procure  TEL to serve  written
          notice on the Purchaser,  in each case  confirming that all conditions
          precedent  to the  Newco  Sale  are  satisfied  and  that  TEL and the
          Purchaser  each  has an  unconditional  obligation  pursuant  to  this
          agreement  to execute and  complete  the Newco  Share Sale  Agreement.
          Accordingly,  TEL will have ceased to be the  beneficial  owner of the
          Newco Shares before the Hivedown Agreement is entered into.

          calculated   in   accordance   with   Schedule  3  and  the   relevant

          Newco Technology Agreements.

     5.2  ICI agrees,  pending the execution and delivery of the  Implementation
          Agreements (or the earlier termination of this agreement),  to conduct
          each of the Businesses  only in the Ordinary  Course of Business.  ICI

          remedied by ICI or its  Affiliates  at no cost to the Purchaser or, as
          the case may be TAI or TCI or Newco,  before the TEL Completion  Date,
          then,  provided the  Purchaser or its  Affiliates  have not  knowingly
          caused or contributed  to such Material  Adverse Effect (to the extent
          it would not have  constituted  such a Material Adverse Effect without
          such  contribution),  the  Purchaser  shall have the right,  by notice
          served on both ICI and DuPont at any time  during the period  from the
          date of this  agreement  to  immediately  prior to the TEL  Completion
          Date, to terminate its obligation to purchase the Newco Shares and the
          Americas  Shares  which in the event of  exercise of such right by the
          Purchaser shall be its exclusive remedy and shall extinguish any claim
          by the Purchaser or any of its Affiliates for damages (whether arising
          in contract,  tort or  otherwise) in  connection  with this  agreement
          provided that on such  termination  the  provisions of sub-Clause  2.6
          shall apply mutatis mutandis.

    10.2  In the  event  that  there  is a  dispute  as to  whether  a right  to
          terminate under  sub-Clause 10.1 exists,  the matter shall be referred
          to  the  Independent  Expert  for  determination  in  accordance  with
          sub-Clause  11.2.  If  completion  of the Sale  Agreements  would have
          occurred but for the application of the provisions of sub-Clause 10.1,
          and if the  determination  is that  the  right to  terminate  does not
          exist, the date of that  determination  shall be treated as the Record
          Date for the purposes of sub-Clause 2.5 and this Clause shall apply in
          relation to the new Record Date.

    10.3 For the purposes of this Clause 10:

          "TRIGGER EVENT" means:

          10.3.1  any  amendment  to  or   variation   of  the   Initial   Newco
                  Disclosure   Documents  or  the  Initial  Americas  Disclosure
                  Documents or other disclosure  pursuant to sub-Clauses 6.3 and
                  9.2 in the period  following  signature of this  agreement and
                  before  the TEL  Completion  Date in  respect of any matter or
                  thing  which  but  for  notification  to the  Purchaser  under
                  sub-Clauses 6.3 and 9.2 above would constitute a breach of the
                  Warranties (as defined in sub-Clauses 6.2 and 9.1) if they had
                  been  given at the  date of this  agreement  or the  Purchaser
                  otherwise  becoming  aware,  without  being in  breach of this
                  agreement,  of a matter  or thing  which  would  constitute  a
                  breach of such Warranties,  if they had been given at the date
                  of this agreement; or

<PAGE>

          10.3.2  without prejudice to sub-Clause  10.3.1 above,  where any such
                  amendment or variation is made to correct an error or omission
                  in the information  contained in the Initial Newco  Disclosure
                  Documents or the Initial Americas  Disclosure  Documents,  the
                  Purchaser  shall be entitled to use such  information  for the
                  purpose  of  calculating  whether,  together  with  any  other
                  Trigger Event(s), a Material Adverse Effect has occurred; or

          10.3.3  contractual  terms not being available  (immediately  prior to
                  the expiry of the period  referred to in sub-Clause  10.1) for
                  the Newco Business to be supplied,  for a period of at least 2
                  years following the Completion  Date, with volumes of ilmenite
                  ore consistent  with those consumed by the Newco Business over
                  the 12 months  ending on the date of this  agreement at prices
                  substantially  similar  to those  payable by TEL under the WSL
                  Contract from time to time.

          "MATERIAL ADVERSE EFFECT" means a diminution in the aggregate value of
          the Americas  Business and the Newco  Business  having regard to their
          aggregate Enterprise Value as determined by reference to Schedule 3 of
          US$35,000,000  or more as a result of any one or more  Trigger  Events
          occurring   prior  to  the  TEL  Completion  Date  ignoring  any  such
          diminution:  (a) which would be reflected in an adjustment pursuant to
          the  provisions  of this  agreement or the Sale  Agreements  as at the
          Completion Date to the aggregate consideration for the purchase of the
          Americas Shares or the Newco Business;  and (b) to the extent that the
          diminution  in  value  has  been  remedied  by ICI at no  cost  to the
          relevant  Companies  or  Businesses  Provided  that where any  adverse
          effect  arising  from one or more Trigger  Event(s) is not  reasonably
          capable of calculation in monetary terms, the question as to whether a
          Material  Adverse  Effect has occurred  whether  wholly or partly as a
          result of such Trigger Event(s) shall,  failing  agreement between the
          parties, be determined by the Independent Expert.


      11  INDEPENDENT ACCOUNTANT AND EXPERT


    11.1  INDEPENDENT    ACCOUNTANT

          11.1.1  If  any   party  (a  "COMPLAINANT")   wishes   to  refer   any
                  matter  in  dispute  in   accordance   with   Schedule  3  for
                  determination  under this Clause,  it shall give notice to the
                  others  (or if the  matter  concerns  only  one or some of the
                  others,  then only to such  other or  others)  (the  "OTHERS")
                  requiring the appointment of an independent accounting firm of
                  international   reputation  (the  "INDEPENDENT   ACCOUNTANT").
                  Accounting firms who have acted as auditors of the Complainant
                  or the Others or their respective Affiliates,  during the five
                  years preceding the date of this agreement,  shall be excluded
                  from such  appointment.  If the Complainant and the Others are
                  unable to agree upon the Independent Accountant within 14 days
                  of such  notice,  then  the  Independent  Accountant  shall be
                  appointed by the President for the time being of the Institute
                  of  Chartered   Accountants   in  England  and  Wales  on  the
                  application of either the Complainant or any of the Others.

          11.1.2  If the Independent  Accountant  delays or becomes unwilling or
                  incapable of acting or if for any other  reason the  President
                  for the time being of the  Institute of Chartered  Accountants
                  in  England  and  Wales  thinks  fit  he  may   discharge  the
                  Independent  Accountant  and,  in  the  absence  of  agreement
                  between the Complainant and the Others, appoint another in its
                  place.

<PAGE>

          11.1.3  The Independent  Accountant  shall act as an expert and not as
                  an  arbitrator  and its  decision  shall  (in the  absence  of
                  manifest  error) be final and binding on the  Complainant  and
                  the  Others.  The  Independent  Accountant  shall  afford  the
                  Complainant  and the Others the  opportunity of making written
                  representations to it and shall make its determination  within
                  40 days of its appointment.

          11.1.4  The fees and expenses of the Independent  Accountant  shall be
                  borne by the Complainant and the Others in equal shares unless
                  the Independent Accountant otherwise determines.


    11.2  INDEPENDENT EXPERT

          11.2.1  If  a  Complainant  wishes  to  refer  any  matter  in dispute
                  for determination  under this sub-Clause 11.2, the Complainant
                  may give  notice  to the  Others  requiring  the  matter to be
                  referred to an independent  expert (the "INDEPENDENT  EXPERT")
                  agreed by the Complainant  and the Others.  If the Complainant
                  and the Others are unable to agree upon the Independent Expert
                  within  14 days of such  notice  then the  Independent  Expert
                  shall be  appointed  by the chairman for the time being of the
                  Institute of Arbitrators on the application of the Complainant
                  or any of the Others.

          11.2.2  If the  Independent  Expert  delays or  becomes  unwilling  or
                  incapable  of acting or if for any other  reason the  chairman
                  for the time being of the Institute of Arbitrators  thinks fit
                  he may discharge the Independent Expert and, in the absence of
                  agreement  between the  Complainant  and the  Others,  appoint
                  another in his or her place.

          11.2.3  The  Independent  Expert  shall act as an expert and not as an
                  arbitrator  and his or her  decision  shall (in the absence of
                  manifest  error) be final and binding on the  Complainant  and
                  the  Others.   The   Independent   Expert   shall  afford  the
                  Complainant  and the Others the  opportunity of making written
                  representations  to him  or  her  and  shall  make  his or her
                  determination within 40 days of appointment.

          11.2.4  The fees and expenses of the Independent Expert shall be borne
                  by the  Complainant  and the Others in equal shares unless the
                  Independent Expert otherwise determines.


      12  LIABILITY IN RELATION TO THE NEWCO SALE AND THE HIVEDOWN AGREEMENT

    12.1  The Purchaser agrees for itself and in respect of its Affiliates that,
          other than as  expressly  provided  in this  agreement,  the  Americas
          Implementation Agreements and the Newco Implementation  Agreements, no
          representation  or  warranty  is given  (express  or  implied)  and no
          liability  is  accepted  by ICI,  DuPont  or any of  their  respective
          Affiliates or any of their respective directors,  employees, agents or
          advisers (respectively the "ICI SELLING GROUP" and the "DUPONT SELLING
          GROUP" and  together  the  "SELLING  GROUP"),  as to the  accuracy  or
          completeness  of any  information  in the Data  Rooms (or any  further
          information  supplied  on request  or any  communication  in  relation
          thereto) or as to the  reasonableness  of any assumptions on which any
          of it is based.

    12.2  The Purchaser for itself and in respect of its  Affiliates  (including
          the  Companies  for the purpose of this Clause 12) agrees that,  other
          than as a result  of fraud on the part of  either  any  member  of the
          DuPont  Selling  Group or of any  member of the ICI  Selling  Group as
          relevant (in which case only the members of the relevant Selling Group
          shall be liable):

                  (i) no member of the Selling  Group shall incur any  liability
                      whatsoever  to the  Purchaser  or  any  of its  Affiliates
                      arising out of or in connection  with the  acquisition  of
                      the Newco Shares or the Americas  Shares and entry into by
                      the  Purchaser  of  the  Newco  Sale  Agreements  and  the
                      Americas Sale Agreements; and

<PAGE>

                  (ii)the  Purchaser  shall  have no right of action  whatsoever
                      against any member of the Selling Group in connection with
                      or arising out of the purchase of the Companies;

          both  other  than  as  provided  in  this   agreement,   the  Americas
          Implementation Agreements and the Newco Implementation Agreements.

    12.3  The Purchaser for itself and its Affiliates  undertakes to the Selling
          Group to waive any liability which such parties may incur by reason of
          the  Purchaser's  or its  Affiliates'  use  of or  reliance  upon  any
          information or documentation provided by such party and their advisers
          in  relation to the sale of the  Companies,  other than as provided in
          this agreement,  the Americas Implementation  Agreements and the Newco
          Implementation Agreements.

    12.4  It is agreed that none of ICI,  DuPont,  the Purchaser or any of their
          respective  Affiliates  are partners under this agreement or any other
          agreement  herein referred to for any purpose,  except the partnership
          agreement  dated 20 December 1993 (as amended)  between  Affiliates of
          ICI and Affiliates of the Purchaser with respect to LPC.

    12.5  The Purchaser acknowledges (for itself and its Affiliates) that DuPont
          and ICI have agreed between themselves arrangements in the Agreed Form
          regarding   the   conduct  of  any  claim   under  any  of  the  Newco
          Implementation  Agreements  which also gives rise to or  constitutes a
          claim  under  the  same or  equivalent  provisions  of the  agreements
          between ICI or any of its  Affiliates  (on the one hand) and DuPont or
          any of its Affiliates (on the other hand) relating to the TEL Sale.

          If DuPont  notifies the Purchaser  that the conduct of any claim under
          any  of the  Newco  Implementation  Agreements  is to be  assumed  and
          controlled by ICI or any of its  Affiliates  in  accordance  with such
          arrangements  then the Purchaser  agrees  (subject to the terms of the
          Newco Implementation Agreements) to co-operate and deal accordingly so
          that references in the Newco Implementation Agreements to "the Seller"
          in the  context of the  conduct  of any such claim  shall be deemed to
          mean ICI or any of its  Affiliates  and the Purchaser  (for itself and
          its Affiliates)  acknowledges that any payment or settlement by ICI or
          any  of  its  Affiliates  to or  with  the  Purchaser  (or  any of its
          Affiliates)  in respect of any claim made by the  Purchaser (or any of
          its  Affiliates)  against  DuPont or its  Affiliates  under any of the
          Newco   Implementation   Agreements  shall  discharge  DuPont  or  its
          Affiliates'  liability  to the  Purchaser  (or any of its  Affiliates)
          under any such Newco Implementation Agreement in respect of such claim
          to the extent of any payment or settlement so made.  The provisions of
          this Clause are without prejudice to the Purchaser's  rights under the
          Newco Implementation Agreements.

    12.6  It is agreed  between  DuPont  and the  Purchaser  (for  itself and on
          behalf of Newco) that in circumstances where the subject matter of any
          claim under any of the Newco Implementation Agreements also gives rise
          to or constitutes a claim or dispute  between DuPont or its Affiliates
          and  Newco  under  or  pursuant  to the  Hivedown  Agreement  then the
          provisions  of the Newco  Implementation  Agreements  dealing with the
          notification,   assistance  and  conduct  of  any  claim,  dispute  or
          proceedings  shall  prevail  over and override  any  corresponding  or
          similar provisions contained in the Hivedown Agreement.  The Purchaser
          shall procure that Newco complies with the provisions of this Clause.

    12.7

          12.7.1  ICI,   DuPont   and  the   Purchaser   agree   to   co-operate
                  generally and take all steps which may  reasonably be required
                  (including without limitation making appropriate  applications
                  to the  relevant  governmental  and/or local  authorities)  to
                  arrange  for  the  transfer  or  assignment  to  Newco  or the
                  re-issue in the name of Newco of each of the Permits  (insofar
                  as they  relate to the Newco  Business)  with  effect from the
                  Completion  Date in each case upon  terms  which  will  enable
                  Newco to continue to conduct  the Newco  Business  with effect
                  from the Completion Date  substantially in the manner in which
                  the Newco Business is conducted prior to the Completion  Date.
                  Any  direct  costs  arising  from the  obligations  under this
                  sub-Clause  12.7 will be divided  equally  among the  parties.
                  Furthermore,  each of the  parties  shall  use all  reasonable
                  efforts to effect each such  transfer,  assignment or re-issue
                  as promptly as practicable after the date of this agreement.

<PAGE>

          12.7.2  ICI and DuPont shall  together use  reasonable  endeavours  to
                  obtain such  consents  from third parties as may be reasonably
                  required to enable Newco to obtain the benefit of the software
                  licences  which are  necessary  for the operation of the Newco
                  Business as at the  Completion  Date at no additional  licence
                  fee.

          12.7.3  If such  consents  are not  obtained,  ICI  and  DuPont  shall
                  procure such additional software licences as are necessary for
                  the  operation  by  Newco  of  the  Newco  Business  as at the
                  Completion  Date.  ICI and DuPont  shall each be liable for 50
                  per cent of the  costs  of such  additional  software  licence
                  fees.

    12.8  Other than in respect of the members of the Selling Group's compliance
          with the provisions of sub-Clause  12.7, the Purchaser  hereby accepts
          and  agrees  that none of the  Selling  Group  shall be liable for any
          failure or refusal by any relevant  governmental or local authority to
          arrange or effect the transfer or  assignment to Newco or the re-issue
          in the name of Newco of any of the Permits as aforesaid.

    12.9  It is  agreed  between  DuPont  (for  itself  and  on  behalf  of  its
          Affiliates) and the Purchaser (for itself and on behalf of Newco) that
          the  indemnity  given by Newco in  favour of TEL in  respect  of Newco
          Liabilities (as defined in the Hivedown  Agreement) pursuant to Clause
          7.3 of the Hivedown  Agreement (the "NEWCO INDEMNITY") shall not apply
          if and to the extent  that the  subject  matter of any claim under the
          Newco  Indemnity  also  gives  rise to or  constitutes  a claim by the
          Purchaser and/or relevant Purchaser Affiliate under or pursuant to the
          Newco Share Sale Agreement.

   12.10  For the purposes of sub-Clauses 12.7 and 12.8 the expression "PERMITS"
          shall  include any  registrations  which may be required for Newco for
          taxation purposes.

   12.11  With effect from the Record Date, or earlier with the agreement of the
          parties (such agreement not to be unreasonably withheld),  the parties
          shall use such reasonable endeavours as they are each able to do so as
          to procure that TEL and Newco meet their  obligations  under the first
          sentence of paragraph 3 of Schedule 7 of the Hivedown Agreement (as if
          the obligations  under the first sentence of paragraph 3 had come into
          effect on the Record Date, or earlier as aforesaid) but subject to the
          provisions  of paragraph  13 of Schedule 7 of the Hivedown  Agreement.
          For the purpose of this sub-Clause 12.11,  references to "consents" in
          such paragraph 3 shall be deemed to include the Consents.

   12.12

          12.12.1 If the  Purchaser  (which for the  purpose of this  sub-Clause
                  12.12  shall  not  include  its  successors  in  title) or any
                  relevant  Affiliate  ("PURCHASER  COMPANIES")  has  not  by  1

          15.1.2  "REPRESENTATIVES"  means  Affiliates,   directors,   officers,
                  employees,  agents  or  representatives  of any  party  or its
                  Affiliates,  and  their  respective  solicitors,  accountants,
                  consultants and financial advisers.

    15.2  Each  party  undertakes  for a period of 5 years from the date of this
          agreement   (subject  to  such  other  period  specified  in  a  Newco
          Implementation  Agreement or an Americas  Implementation  Agreement in
          relation to particular  information)  following the Completion Date to
          maintain  Confidential  Information  received by it, its Affiliates or
          its  Representatives  relating to any other party or any other party's
          Affiliates   in  confidence   and  not  disclose   that   Confidential
          Information  to any person other than its  Representatives,  except as
          required  by law or any  competent  regulatory  authority  or with the
          prior  written  approval  of such  other  party,  which  shall  not be
          unreasonably withheld or delayed.

<PAGE>

    15.3  Each party  undertakes  only to disclose to its  Representatives  such
          Confidential  Information  relating to the disclosing party or parties
          or the  disclosing  party's or parties'  Affiliates  as is  reasonably
          required for the purposes of  performing  the  obligations  under this
          agreement  or the  Newco  Implementation  Agreements  or the  Americas
          Implementation  Agreements and only to those  Representatives  whom it
          has  informed  of  the   confidential   nature  of  the   Confidential
          Information  and who  undertake  to keep it  confidential.  Each party
          shall be responsible for breach of such confidentiality undertaking by
          it or  its  Representatives  and  undertakes  to  indemnify  and  hold
          harmless  the  disclosing  party or  parties,  its  Affiliates  or any
          successor to such business  against all actions,  proceedings,  costs,
          claims,  demands,  liabilities,  losses or expenses  (including  legal
          expenses) arising from such breach.

    15.4  In the event that,  after  receipt of  Confidential  Information,  any
          party,  or any  person or  Representative  to whom it has  transmitted
          Confidential Information, becomes legally required (by oral questions,
          interrogatories,  requests for  information  or  documents,  subpoena,
          civil  investigation,  demand or similar  process,  or  otherwise)  to
          disclose any of the  Confidential  Information  received,  the legally
          compelled party shall provide the disclosing party with prompt written
          notice of that  requirement  so that the  disclosing  party may seek a
          protective order or other appropriate  remedy but shall not be obliged
          to delay  disclosure if to do so would be in breach of any  conditions
          for such disclosure imposed by the authority compelling disclosure and
          in any event should the disclosing  party not be successful in seeking
          or  obtaining a  protective  order or other  appropriate  remedy,  the
          disclosing  party shall waive  compliance  with the provisions of this
          agreement  for such  particular  case to enable the legally  compelled
          party or its Representative to comply with any such legal requirement.

    15.5  Each party will only use (or permit the use by its Representatives of)
          the Confidential Information received by it or its Representatives for
          the purposes of the transactions contemplated by this agreement.

    15.6  Nothing in this Clause 15 shall make a party liable to any other party
          for any of its  Representatives in relation to breaches of this Clause
          which  occur  after  the time  when such  Representative  becomes  the
          Representative  of another  party to this  agreement.  Nothing in this
          sub-Clause  15.6  shall  affect  any  duty  owed  personally  by  such
          Representative.

    15.7  Nothing in this Clause 15 shall  supersede or vary the  obligations of
          the parties  set out in any of the Newco  Technology  Agreements,  the
          Americas   Technology   Agreements   or  any  other   agreement,   the
          confidentiality  provisions  of  which  exist  on  the  date  of  this
          agreement.

    15.8  Notwithstanding any provision to the contrary,  the provisions of this
          Clause shall survive termination of this agreement.


      16  GUARANTEES AND INDEMNITY

    16.1  Each party  undertakes to procure  that,  subject to the terms of this

          a basis for such release),  the release of ICI and/or DuPont or any of

          specifically  identified in the Final Disclosure  Letter applicable to
          the Newco Share Sale  Agreement for the purposes of this provision and
          pending such release the Purchaser will indemnify and keep indemnified
          each  of the  members  of the  Selling  Group  from  and  against  any
          liability (including any claim, demand, proceeding, costs, damages and
          expenses)  which they may suffer or incur under or in relation to such
          guarantees.

          result of the failure of the Purchaser to comply with its  obligations
          under paragraph 2 of Schedule 4.

          (except  those  set  out  in  this  agreement  or  any  Implementation
          Agreement)  and waives all rights  and  remedies  which,  but for this
          sub-Clause,  might otherwise be available to it in respect of any such
          representation,  warranty,  collateral  contract  or other  assurance,

     (4)  On the Completion  Date the relevant  Purchaser  Affiliate will pay or
          procure  the  payment of (in  accordance  with the  provisions  of the
          relevant  Share  Sale  Agreement  or  as  appropriate,   the  Hivedown

          shall pay or procure the payment of (in accordance  with the provision
          of the LPC Termination Agreement) an amount equal to the consideration

     (5)  In relation to the Americas Share Sale Agreements:

          (a)     the  Final  Consideration  for  the  relevant Company shall be
                  determined by the following formula:

                  Final  Consideration  = EV minus  AND  minus  NWC 28 plus ANWC
                  (excluding  in  the  case  of TAI  in  relation  to any of the
                  foregoing  any  item  or  matter   attributable   to  the  LPC
                  Interests) plus in the case only of TAI LV

                  Where (in relation to the relevant Company):

                  EV = Enterprise Value

                  AND = Actual Net Debt

                  NWC28 = Net Working Capital as at 28 February 1998

                  ANWC = Actual Net Working Capital

                  LV = X (value of LPC Interests)

                  The figure  represented by X in this paragraph (5) shall be as
                  agreed between ICI and the Purchaser.

          (b)     After  the  Completion  Date ICI  shall  prepare  a completion
                  statement  as at the  Completion  Date which  shall  contain a
                  statement  of  the  Final  Consideration  in  accordance  with
                  paragraph 5(a) above based on ICI's  calculations  (the "FINAL
                  COMPLETION  STATEMENT").  The Final Completion Statement shall
                  be  prepared  using  ICI's  normal  accounting   policies  and
                  practices  as set out or  referred  to in  ICI's  Controller's
                  Manuals  as applied by the  relevant  Company on a  consistent
                  basis  and shall be  submitted  by ICI to ICI's  Auditors  for
                  review.

          No final  consideration  adjustment  will be made for the Newco Shares
          under  the  Newco  Share  Sale  Agreement  and the  provisions  of the
          Hivedown Agreement will apply. The provisions of sub-paragraphs 1(5) -
          (9) inclusive will not apply to the Newco Share Sale Agreement.

     (6)  Within  45 days of the  Completion  Date,  ICI  shall  issue the Final
          Completion Statement (distinguishing between the Americas Business and
          the LPC Business) for the relevant Companies to the Purchaser together
          with a copy  of a  report  by  ICI's  Auditors  addressed  to ICI  and
          substantially  in the form set out in Annex 2 to the  effect  that the
          Final  Completion  Statement has been prepared in accordance with this
          agreement.  Although it is ICI's  responsibility  to prepare the Final
          Completion Statement, ICI will require the assistance of the employees
          of the relevant Purchaser Affiliates to fulfil this responsibility and
          the Purchaser shall ensure such assistance is provided promptly and at
          no  charge.   Immediately  after  delivery  of  the  Final  Completion
          Statement,  the Purchaser's  Auditors shall have the right, subject to
          the Purchaser delivering to ICI's Auditors a signed letter in the form
          set out in Annex 4, to review the Final Completion Statement and ICI's
          Auditors  working papers relating to the Final  Completion  Statement.
          Within 45 days of delivery to the  Purchaser  of the Final  Completion
          Statement  and  ICI's  Auditors  report  (each  of  which  shall be in
          English) to the Purchaser's  designated location,  the Purchaser shall
          give  notice  to ICI in  writing  of any item or  items  in the  Final
          Completion Statement which it wishes to dispute and the basis on which
          it  disputes  that item or those  items and the  changes  to the Final
          Completion  Statement which the Purchaser  believes should be made and
          ICI and the Purchaser shall use their reasonable endeavours to resolve
          that  dispute.  Any items in respect of which the  Purchaser  does not
          give  such  notice  will  be  deemed  to  have  been  accepted  by the
          Purchaser.  Any written resolution reached by ICI and the Purchaser on
          any  disputed  item  shall be final,  conclusive  and  binding  on the
          parties.

<PAGE>


     (7)  If ICI and the Purchaser agree the Final Completion Statement then any
          adjusting payments referred to in paragraph (9) below shall be made by
          the paying party within seven days of being agreed by the parties.

     (8)  If ICI and the  Purchaser  fail to agree on any  element  of the Final
          Completion  Statement  within 14 days  after the  Purchaser  has given
          notice  in  writing  to ICI of any  item(s)  in the  Final  Completion
          Statement  which the Purchaser  wishes to dispute (in accordance  with
          paragraph  (6)  above)  then  any  agreed  amounts  shall  be  paid in
          accordance  with  the  preceding  paragraph  and  any  dispute  may be
          referred by either ICI or the  Purchaser  for final  determination  in
          accordance  with  sub-Clause  11.1 of this  agreement  and any amounts
          thereby found to be due shall be paid by the relevant  party not later
          than seven days after such final determination.

     (9)  When the Final  Consideration  is agreed or  otherwise  determined  in
          accordance with the three preceding paragraphs the following adjusting
          payments shall be made:

          (a)     an amount  equal to the  difference  between (i) the Estimated
                  Consideration  and (ii) the Final Consideration; and

          (b)     interest  (calculated  on a  day-to-day  basis and  compounded
                  monthly) at the Interest  Rate on the amount in paragraph  (9)
                  (a) above  from the  Completion  Date to the date of  payment,
                  calculated on a day to day basis

          which shall be paid by the  relevant  ICI  Affiliate  to the  relevant
          Purchaser Affiliate (or vice versa, as appropriate).

    (10)  In this  Schedule,  references to lines of A Forms have been chosen by
          ICI and are  believed  in good faith to  correspond  to the matters to
          which they refer.  If,  however,  that  reference when compared to the
          matter it  describes or refers to is  incorrect  then,  subject to the
          Purchaser's  agreement,  there  shall be  substituted  for  that  line
          reference  another line  reference (if any) which  corresponds  to the
          matter described or referred to. Any dispute between the Purchaser and
          ICI as to any matter  arising under this  sub-paragraph  (10) shall be
          referred for final determination in accordance with sub-Clause 11.1 of
          this Agreement.

                                FURTHER ASSURANCE
                                   (CLAUSE 17)

       1  ICI,  DuPont and the Purchaser  recognise that it may be necessary for
          certain of the  excluded or shared  assets to be used by the ICI Group
          and/or the DuPont Group and the Companies  after the Completion  Date.
          If any such assets are  identified  by ICI,  DuPont or the  Purchaser,
          ICI,  DuPont and the Purchaser will negotiate in good faith to reach a
          sharing arrangement (on a fair, equitable and cost-effective basis) in
          relation to such assets.

       2  In accordance with its obligations  under the Transfer of Undertakings
          (Protection of Employment)  Regulations 1981 (as amended the "TRANSFER
          REGULATIONS")  in relation to the  employees  to be employed by Newco,
          the Purchaser  shall  promptly  provide TEL, ICI or its  Affiliates in
          writing with such  information  as is  reasonably  necessary to enable
          TEL, ICI or its  Affiliates to carry out the duties under  Regulations
          10(2)(d) and 10(6) of the Transfer  Regulations and the obligations to
          consult under the Transfer  Regulations and Council  Directive  77/187
          EEC.

       3 ICI shall be responsible for the incorporation of Newco.

       4

     4.1  Up until  the  Completion  Date (or the  earlier  termination  of this
          agreement) the parties agree in good faith to co-operate generally and
          take all steps as may  reasonably be required (in so far as each party
          is able to do so and the same is permitted by law or regulation):-

          (a)     for TEL to split  with  Newco  the WSL  Contract  (whether  by
                  partial assignment or otherwise) on a PRO RATA volume basis by
                  reference  to that  proportion  of the  ilmenite  ore supplied
                  under the WSL  Contract  which has been  consumed by the Newco
                  Business  during  the 12  months  ending  on the  date of this
                  agreement (THE "AGREED GRIMSBY VOLUME PROPORTION"); and/or

          (b)     for TEL to  effect a  sub-contract  arrangement  in  favour of
                  Newco for a period of two years  from the  Completion  Date in
                  respect of the WSL Contract  giving to the Newco  Business the
                  Agreed Grimsby Volume Proportion; and/or

          (c)     for contractual  terms to be made available to Newco for Newco
                  to be supplied,  for a period of at least two years  following
                  the Completion  Date,  with volumes of ilmenite ore consistent
                  with those  consumed by the Newco  Business over the 12 months
                  ending on the date of this agreement (THE "GRIMSBY  HISTORICAL
                  VOLUME"); and/or

          (d)     if  prior  to  the  Completion  Date  the  volumes of ilmenite
                  ore  contractually  available for supply to the Newco Business
                  are less than the Grimsby  Historical Volume, for any ilmenite
                  ore made  available  during the  period  from the date of this
                  agreement until the second  anniversary of the Completion Date
                  to TEL or any other  companies  to be sold to DuPont or any of
                  its Affiliates  upon  completion of the TEL Sale (the "TIOXIDE
                  GROUP") pursuant to any new contract ("NEW CONTRACT") which is
                  entered into after the date of this agreement and prior to the
                  TEL  Completion  Date by any member of the Tioxide Group to be
                  shared as between the Newco  Business  and the  Tioxide  Group
                  other than the Newco Business (the "REVISED TIOXIDE Group") so
                  that the Newco Business is entitled to receive a proportion of
                  such  ilmenite  ore  equal  to  the  Agreed   Grimsby   Volume
                  Proportion   but  so  that  the   aggregate  of  ilmenite  ore
                  contractually  available to the Newco  Business  under any New
                  Contracts  shall  not,  when  taken  together  with any  other
                  contractual  arrangements  available to the Newco Business, be
                  required to exceed the Grimsby Historical Volume.

<PAGE>

     4.2  If the volumes of ilmenite ore  contractually  available for supply to
          the Newco  Business at the  Completion  Date are less than the Grimsby
          Historical  Volume,  Dupont  shall use all  reasonable  endeavours  to
          procure (if permitted by law or regulation) that any ilmenite ore made
          available  during  the  period  of two  years  immediately  after  the
          Completion  Date to the  Revised  Tioxide  Group  pursuant  to any new
          contract  ("NEW  TIOXIDE  CONTRACT")  which is entered  into after the
          Completion  Date is  shared as  between  the  Newco  Business  and the
          Revised  Tioxide  Group so that the  Newco  Business  is  entitled  to
          receive a proportion of such ilmenite ore equal to the Agreed  Grimsby
          Volume  Proportion  but so  that  the  aggregate  of  ilmenite  ore so
          contractually  available to the Newco  Business  under any New Tioxide
          Contracts  shall not, when taken  together with any other  contractual
          arrangements  available to the Newco  Business,  be required to exceed
          the Grimsby Historical Volume.

     4.3  If the volumes of ilmenite ore  contractually  available for supply to
          the Revised  Tioxide  Group at the  Completion  Date are less than the
          volumes of ilmenite ore consumed by the Revised Tioxide Group over the
          12 months ending on the date of this  agreement,  the Purchaser  shall
          use all  reasonable  endeavours  to procure  (if  permitted  by law or
          regulation)  that any ilmenite ore made available during the two years
          immediately  after the Completion Date to the Newco Business  pursuant
          to any new contract which is entered into after the Completion Date is
          shared as between the Newco Business and the Revised  Tioxide Group so
          that each shall be entitled  to receive  volumes by  reference  to the
          proportions  of ilmenite  ore  consumed by the Newco  Business and the
          Revised  Tioxide  Group  under the WSL  Contract  during the 12 months
          ending on the date of this agreement.

     4.4  Neither ICI (for itself or its Affiliates),  Dupont (for itself or its
          Affiliates)  nor the  Purchaser  (for itself or its  Affiliates)  will
          apply any price mark up  pursuant to the  arrangements  referred to in
          sub-clauses  4.1(d),  4.2 and 4.3  (save,  in the case of ICI,  or its
          Affiliates, as consistent with practice at the date hereof).

       5  On or before the  Completion  Date the  Purchaser  shall  establish or
          nominate a retirement  benefits  scheme which satisfies the conditions
          set out in Schedule 4 of the Newco Share Sale Agreement.

       6  ICI,  DuPont and the  Purchaser  acknowledge  that  certain  property,
          rights and assets of or relating  to or used in the Newco  Business as
          at the Transfer Time may not  exclusively  relate to or be exclusively
          used in the Newco  Business as at such time. If the Purchaser  becomes
          aware of any such property,  right or asset at any time after the date
          of  this  agreement  and  prior  to the  date  falling  twelve  months
          following the  Completion  Date and serves  notice  thereof on ICI and
          DuPont,  ICI (prior to the Completion Date) and DuPont  (following the
          Completion Date) shall unless otherwise agreed:

                  (i) make  arrangements  for  the  continued  use of the  same,
                      subject to the same terms  (including  as to cost and use)
                      as applied immediately prior to the Completion Date; or

                  (ii)to the extent such continued use is not  permitted,  make,
                      insofar as reasonably  possible,  arrangements for the use
                      of such property, right or asset as is equivalent thereto,
                      from and after the Completion Date.

          To the extent that third party  consents are required,  the provisions
          of Schedule 7 of the Hivedown  Agreement shall apply MUTATIS  MUTANDIS
          and in  relation  to  sub-paragraph  (ii) the  aggregate  of  payments
          required  to  be  made  under  the  existing   arrangements  and  such
          equivalent  arrangements  (taking  into  account any increase in costs
          thereunder)  shall be borne  equitably  between  ICI,  DuPont  and the
          Purchaser.

<PAGE>

           This  Paragraph  6 shall not apply to the extent  that the use in the
           Newco  Business  of the  property,  right  or asset  in  question  is
           otherwise   expressly   provided  for  in  the  Newco  Implementation
           Agreements.

          NOTES:

       1  Pension Liability  (Approx.  US$250,000) is accounted for according to
          US rules (FAS87 etc.) in A Form.  Therefore no reconciling  difference
          between US and UK GAAP.

       2  ICI A Forms do not  report  deferred  tax for  ICI's US  subsidiaries.
          However any deferred tax in the US GAAP accounts is readily analysable
          into its LPC and  Sulphate and is estimated to derive to the extent of
          some 99 per cent. from LPC's tax depreciation.

      absolute  discretion to take such action as Newco shall deem  necessary or
      desirable to  prosecute,  settle or  compromise  such  Materials  Business
      Debtor or Materials Business Claim, or to avoid, dispute,  resist, appeal,
      compromise  or contest any related  counter-claim  to the extent that such

      conduct of any related proceedings, negotiations or appeals.

      benefit of any rights accruing against third parties,  whether such rights
      have or have not accrued or become  enforceable  as at the Transfer  Time)
      and of all the provisions of this Agreement.

<PAGE>

10.2  SHARED SUPPLIER CONTRACTS

      TEL agrees,  to the extent that it is able, to make onward supply of those
      goods or services  provided under Shared Supplier  Contracts to the extent
      that  those  goods or  services  would  have been  utilised  by TEL in the
      Business  had it not been  transferred  to Newco  pursuant to the terms of
      this Agreement on the basis that Newco shall bear its proportionate  share
      of the net cost and expenses under such Shared Supplier Contracts.

10.3  ENVIRONMENTAL AUTHORISATIONS

      TEL shall give all reasonable assistance (other than financial assistance)
      to  Newco  in  applying  for,  or  arranging  for  the  transfer  of,  the

      shall account to TEL for the same as soon as reasonably  practicable after
      receipt.

10.6  NEWCO TAXATION LIABILITIES

      Newco shall be responsible  for all  liabilities  to Taxation  incurred or
      owing by it  (whether or not due and  payable) in respect of the  Business
      following the Transfer  Time  including any stamp duty arising as a result
      of this Agreement or its completion.

11.   VAT

11.1  TEL and  Newco  intend  that  article 5 of the  Value  Added Tax  (Special
      Provisions)  Order 1995  ("ARTICLE 5") shall apply to the sale or sales of
      the Business under, or procured under, this Agreement, so that the sale or
      sales are treated as neither supplies of goods nor supplies of services.

11.2  If  nevertheless  any VAT is  payable  on any  supply by TEL or any supply
      which is  procured  by TEL under this  Agreement,  Newco  shall pay it the
      amount  of that VAT in  addition  to the  price  (and if Newco  delays  or
      defaults in  complying  with its  obligations  under Clause 11.3 pay it an
      amount  equal to any  interest  and  penalties  imposed by HM Customs  and
      Excise  (whether on TEL or another person) arising out of the treatment by
      TEL and Newco of the sale as described in Clause 11.1 above).

<PAGE>

11.3  Without  limiting  Clause  11.2,  VAT shall be  treated  as  payable if HM
      Customs and Excise rule that it is payable  after full  disclosure  of all
      material  facts.  If they have done so before the Transfer  Time,  the tax
      shall be payable by Newco on the Transfer  Time against  issue of a proper
      VAT invoice (issued by TEL or other appropriate person) in respect of such
      VAT. If they do so on or after the Transfer Time, the tax shall be payable
      by Newco  within  five days after TEL gives  Newco  written  notice of the
      ruling  together  with a  proper  VAT  invoice  (issued  by  TEL or  other
      appropriate person) in respect of that VAT.

11.4  If Newco  fails to pay the amount of the tax on the due date under  Clause
      11.3, it shall pay Default Interest on that amount from the due date until
      actual payment (excluding any period for which interest  indemnified under
      Clause 11.2 runs) compounded  monthly except to the extent to which TEL is
      fully  compensated  for Newco's delay by reason of the indemnity in Clause
      11.2 extending to interest.

11.5  With a view to procuring that article 5 applies, Newco:

      11.5.1shall ensure that Newco is  registered  for VAT not later
            than the date of the Transfer Time;

      11.5.2warrants  that  the  Business  Assets  are to be  used by  Newco  in
            carrying on the same kind of  business  as that  carried on by TEL's
            Group and its Affiliates;

      11.5.3warrants  that  Newco  has,  or  will  by the  relevant  date  have,
            properly  made an  election  to waive  exemption  in respect of each
            Non-Exempt  Property  with  effect  from a day not  later  than  the
            relevant date (having obtained the written  permission of HM Customs
            and Excise if  necessary)  and has, or will by that date have,  duly
            given to HM  Customs  and  Excise the  written  notification  of the
            election required to make the election effective; and

      11.5.4covenants  that  Newco will not revoke  the  election  within  three
            months after the relevant date.

      In this paragraph "RELEVANT DATE" has the same meaning as in paragraph (2)
      of article 5.

11.6  TEL and Newco  envisage  that s. 49 of the Value Added Tax 1994 will apply
      to the sale and purchase of the Business  Assets under this  Agreement but
      intend that TEL should retain the records referred to in that section, and
      accordingly:

      11.6.1notwithstanding   anything  in  this  Agreement  TEL  shall  not  be
            required to deliver to Newco the records referred to in s.49;

<PAGE>

      11.6.2TEL shall  make a request to HM  Customs  and Excise  under s.49 for
            the records to be preserved by TEL;

      11.6.3if or for  so  long  as  that  request  is not  granted,  TEL  shall
            preserve  the  records on behalf of Newco for such  period as may be
            required  by  law,  and  shall  during  that  period   permit  Newco
            reasonable access to them to inspect or make copies of them; and

      11.6.4TEL may fulfil its  obligations  under  Clause  11.6.3 by  procuring
            that a  future  transferee  of its  business  or  any  other  person
            preserves the records and permits  reasonable access as mentioned in
            that paragraph,  in which case TEL shall notify Newco of the name of
            that person.

11.7  In respect of each Non-Exempt Property mentioned in Clause 11.5.1 either:

      11.7.1without  prejudice to that  subclause,  Newco shall on or before the
            Transfer Time give to TEL evidence  reasonably  satisfactory  to TEL
            that the election has been made and written  notification duly given
            in accordance with that subclause; or

      11.7.2if Newco  does not give  that  evidence,  it shall be  assumed  that
            those  things  have not been done and  notwithstanding  Clause  11.3
            Newco  shall  on the  Transfer  Time  pay to TEL the  amount  of VAT
            chargeable  in respect of the relevant  Non-Exempt  Property on that
            assumption but any  forbearance of TEL to insist on its rights under
            this  subclause  shall be without  prejudice to its rights under the
            preceding provisions of this clause.

11.8  References in Clause 11.5 to Newco shall be construed as references to the
      transferee within the meaning of the corresponding  provision of article 5
      if different.

12.   AVAILABILITY OF INFORMATION

      Each of TEL and Newco  shall  make  available  to the other free of charge
      upon written  request all  information  (or copies of any  information  in
      writing) which the other may reasonably  require  relating to the Business
      and the  Business  Assets  (including,  without  limitation,  any  records
      required  for the  purposes  of VATA or the  Regulations  or  relating  to
      taxation of any kind  (including  Taxation)  but not for the  avoidance of
      doubt the Customer Contracts or the Commercial and Marketing Know-How).

13.   INDEPENDENT ACCOUNTANT

13.1  If either party wishes to refer any matter in dispute in  accordance  with
      the  provisions  of Clause 3 or Schedule 14 for  determination  under this
      Clause it shall give notice to the other  requiring the  appointment of an
      independent accounting firm of international  reputation ("THE INDEPENDENT
      ACCOUNTANT")  excluding  accounting  firms who have acted as  auditors  of
      either  party or of any of their  Affiliates  in the last 5 years.  If the
      parties are unable to agree upon the Independent Accountant within 14 days
      of such notice, then the Independent  Accountant shall be appointed by the
      President for the time being of the Institute of Chartered  Accountants in
      England and Wales on the application of either party.

<PAGE>

13.2  The Independent Accountant shall act as an expert and not as an arbitrator
      and his  decision  shall (in the absence of  manifest  error) be final and
      binding  on the  parties.  The  Independent  Accountant  shall  afford the
      parties the opportunity of making written representations to him and shall
      make his determination within 40 days of his appointment.

13.3  The fees and expenses of the Independent  Accountant shall be borne by the
      parties  in equal  shares  unless  the  Independent  Accountant  otherwise
      determines.

14.   DEFAULT INTEREST

      Subject as otherwise  provided to the contrary in this  Agreement,  if any
      sum due for  payment  under  this  Agreement  or in  accordance  with this
      Agreement  is not paid on the due date the  party  in  default  shall  pay
      Default  Interest  on that sum from the due date  until the date of actual
      payment calculated on a day to day basis.

15.   GENERAL

15.1  Unless otherwise expressly stated, all claims made and payments to be made
      under this Agreement shall be made in US Dollars. Payments to TEL shall be

      this  Agreement  shall be in US Dollars  and where an amount is not itself
      calculated  in US Dollars,  it shall be  converted  into US Dollars at the
      mid-market  closing  exchange  rate for that  currency  into US Dollars as
      published  in the  London  Edition  of The  Financial  Times  published  2
      Business  Days prior to the date on which the  relevant  payment is due or
      where no such rate is published,  at the rate quoted by Citibank,  N.A. at
      the close of business in London on that date.  This  sub-clause  shall not
      apply to Schedule 14.

15.2  Save as otherwise provided to the contrary in this Agreement, each payment
      to be made under this Agreement shall be made in the currency in which the
      relevant  amount  is  payable,   free  and  clear  of  all  deductions  or
      withholdings  of any kind,  except for those  required by law,  and if any
      deduction or withholding must be made by law, an additional amount will be
      paid which is necessary to ensure that the recipient receives a net amount
      equal to the full amount  which it would have  received if the payment had
      been made without the deduction or withholding.

<PAGE>

15.3  None of the rights or obligations  under this Agreement may be assigned or
      transferred   without  the  written  consent  of  the  other  party  ("the
      Non-Assigning  Party") other than an assignment of the rights (but not the
      obligations) to an Affiliate of the assigning party provided that:

      (a)   such  assignment  shall only be permitted if the  assignment  has no
            adverse effect on the Non-Assigning Party;

      (b)   if the Affiliate to which the rights have been assigned ceases to be
            an  Affiliate  of the  assigning  party,  the rights which have been
            transferred  shall be  re-transferred  to the party which originally
            assigned  those  rights or to  another  Affiliate  of that  original
            assigning party; and

      (c)   it  shall be a  condition  of any such  assignment  that  reasonable
            notice  is  given  in  writing  to the  Non-Assigning  Party  of the
            proposal to assign, (identifying the rights proposed to be assigned,
            the  identity  of the  proposed  assignee  and  such  other  details
            relating thereto as the Non-Assigning Party may reasonably require).

15.4  Save as  otherwise  provided in this  Agreement,  each party shall pay the
      costs and expenses incurred by it in connection with the entering into and
      completion of this Agreement.

15.5  This Agreement may be executed in any number of counterparts, all of which
      taken together  shall  constitute one and the same agreement and any party
      may enter into this Agreement by executing a counterpart.

15.6  No  amendment,  variation or waiver of this  Agreement or any provision of
      this  Agreement  shall  be  effective  unless  it is in  writing  and duly
      executed by or on behalf of both parties.

      the parties relating to the transaction contemplated by this Agreement and

6.1   Failure to Obtain Consents

      6.1.1 Where a landlord's  consent is required and has not been obtained by
            the date hereof in respect of any of the  Properties,  such Property
            will  not,  unless  Newco so  elects  (an  "ELECTED  PROPERTY"),  be
            transferred  on the date  hereof but will be held in trust for Newco
            absolutely  from the date hereof  until such  landlord's  consent is
            obtained  or Newco  requires  the  transfer  or  assignment  of such
            Property to it in accordance  with  paragraph 6.3. TEL shall account

      After the date hereof, TEL shall continue to use all reasonable endeavours
      (assisted  if  necessary  by Newco) to obtain any  outstanding  landlord's
      consent  at  Newco's  cost in  respect  of any  Property  (which is not an
      Elected  Property) and keep Newco  informed of progress in obtaining  such

      provisions:-

            conditions  contained or referred to in the leases relating thereto;
            and

<PAGE>

      (d)   in the  event  that the  landlord  threatens  to  forfeit  the lease

            shall forthwith vacate such Leasehold Property.

6.5   Terms of purchase

      The Properties  are sold together with all easements,  rights and licences
      appurtenant  thereto and all buildings and structures  thereon but subject

                                   SCHEDULE 6

PROVISIONS RELATING TO THE CONTRACTS

(Clause 10.4)

1.    Newco shall with effect from the Transfer  Time carry out and complete for
      its  own  account  the  Supplier  Contracts  and  the  Materials  Customer
      Contracts to the extent that the same have not been  previously  performed
      (whether due for  performance  prior to, on or after the  Transfer  Time).
      Newco  shall  indemnify  TEL  against  all Costs,  claims and  liabilities
      arising  prior  to,  on or after  the  Transfer  Time by  reason  of or in
      connection  with  the   non-performance  or  the  defective  or  negligent
      performance  (whether by TEL or Newco) of the  Supplier  Contracts  or the
      Materials Customer Contracts.

2.    Newco shall be responsible  for and shall  indemnify TEL against any claim
      from  customers  for repair,  replacement,  damage or otherwise  duly made
      before or after the Transfer Time under any guarantees or warranties given
      expressly or by  implication of law by TEL in respect of any goods sold or
      service supplied by TEL prior to the Transfer Time in the Business.

3.    To the extent  that any  payment  is made to TEL in  respect of  Materials
      Customer  Contracts after the Transfer Time, TEL shall receive the same as
      trustee for Newco absolutely,  shall record such payment separately in its
      books  and  shall  account  to Newco  for the  same as soon as  reasonably
      practical after receipt. In determining the liability under this paragraph
      of TEL to account to Newco for amounts  received,  regard  shall be had to
      any  liability  of TEL to account to HM Customs  and Excise for any United
      Kingdom VAT in respect of the supply of goods and/or  services (made under
      any  Materials  Customer  Contract) to which such  amounts  relate and the
      liability of TEL under this paragraph shall be reduced accordingly.

4.    In  determining  the  liability of Newco to reimburse  TEL for any amounts
      paid by TEL to suppliers under Supplier Contracts,  regard shall be had to
      the  extent to which TEL has been or is able to  recover  payment of input
      tax for United Kingdom VAT purposes in respect of supplies of goods and/or
      services  (under a Supplier  Contract)  made to TEL to which such  amounts
      relate and the  liability of Newco under this  Agreement  shall be reduced
      accordingly.

5.    If TEL has prior to the Transfer Time  sub-contracted  the  performance of
      any  contracts  for the supply of goods or other  products  to any person,
      Newco shall  (unless TEL would have been  entitled  under the  contract to
      reject the same and Newco determines to reject the same), on behalf of the
      relevant customer seek or accept delivery from such person of the goods or
      other  products in respect of which such  contract was made and shall make
      the same available for collection by such customer.

                                   SCHEDULE 7

PROVISIONS RELATING TO THIRD PARTY CONSENTS

(Clause 5.4)

1.    Where  any  Business  Asset,   including  any  Materials  Business  Claim,
      Materials Business Debtor, Materials Customer Contract,  Supplier Contract
      and any  property  or asset  leased  by TEL  relating  exclusively  to the
      Business (but excluding the Leasehold  Properties) requires the consent or
      agreement of any third party for the same to be assigned or novated to or,
      in the  case of any  leased  property,  to be  sub-leased  to,  Newco,  (a
      "RELEVANT  BUSINESS ASSET") or any Newco Liability requires the consent or
      agreement of any third party for the same to be  performed  by Newco,  and
      any such consent has not been  obtained  prior to the Transfer  Time,  the
      provisions of this Schedule shall apply.

2.    In  respect of any  Relevant  Business  Asset,  this  Agreement  shall not
      constitute an assignment or a purported assignment thereof, or a sub-lease
      or a  purported  sub-lease  thereof,  to Newco if any such  assignment  or
      sub-lease  would  constitute  a  breach  of  any  agreement,  contract  or
      undertaking  (a  "Relevant  Agreement")  of TEL with or to the third party
      from whom any such consent as is referred to in paragraph 1 is required to
      be obtained, pending such consent being obtained.

3.    TEL and Newco shall jointly use all  reasonable  endeavours  and render to
      each other all reasonable  assistance (not being  financial) to obtain the
      consent of such third party to an  assignment,  or novation  (whichever is
      available)  or (if  neither an  assignment  or novation  is  available)  a
      sub-lease of the Relevant Business Asset. During the period from and after
      the  Transfer  Time until any required  consent  shall be obtained and the
      Relevant Business Asset transferred,  or assigned or novated to Newco, any
      such  Relevant  Business  Asset  shall be held in  trust by TEL for  Newco
      absolutely  with effect from the  Transfer  Time until the same shall have
      been delivered and/or formally  transferred,  assigned or novated to Newco
      and TEL  shall  grant  to Newco  such  powers  of  attorney  as Newco  may
      reasonably  require to enable Newco to vest in itself or otherwise to deal
      with such Relevant  Business  Assets and shall deliver to Newco  forthwith
      upon receipt any notice or other  document  containing or relating to such
      Relevant Business Assets.

4.    This  Agreement   shall  not  constitute  an  assumption  or  a  purported
      assumption of any Newco Liability in respect of which performance  thereof
      by Newco would require the consent or agreement of any third party if such
      assumption  or  purported  assumption  would  constitute  a breach  of any
      Relevant Agreement  pursuant to which the obligation arises.  Newco shall,
      to the  extent  that the same  would not  result in any breach of any such
      Relevant Agreement perform as TEL's  sub-contractor all the obligations of
      TEL  thereunder and indemnify TEL against all  liabilities  (and all Costs
      reasonably incurred by TEL) arising in connection therewith.

<PAGE>

5.    Where  the  performance  by  Newco  of any  Relevant  Agreement  as  TEL's
      sub-contractor  would  result in a breach of any  agreement,  contract  or
      undertaking  with a third party (whether  under the Relevant  Agreement in
      respect of which the obligation  arises or under any other  agreement with
      any other person relevant to the  performance of such Relevant  Agreement)
      Newco shall not perform such obligations as TEL's  sub-contractor  but TEL
      shall continue to perform such obligations on behalf of and at the risk of
      Newco and Newco agrees to indemnify TEL against all  liabilities  (and all
      Costs reasonably incurred by TEL) arising in connection therewith.

6.    TEL agrees and acknowledges  that,  insofar as any Relevant Business Asset
      is  expressed  in  this  Schedule  to be held on  trust  by TEL for  Newco
      absolutely,  any  monies  received  by TEL in  respect  thereof  shall  be
      accounted for by TEL to Newco and any profit arising out of the conduct of
      the Business  utilising any such Business  Asset shall accrue to Newco and
      TEL agrees to pay forthwith to Newco any such  amounts,  less in each case
      an amount equal to the relevant Costs which TEL is entitled to recover and
      deduct from any such payment.

7.    Newco expressly  acknowledges  that insofar as any Newco Liability has not
      been effectively  assumed by Newco and, insofar as the same relates to the
      performance  of any  obligations  under any  Relevant  Agreement  and such
      obligations  are,  pursuant  to the  provisions  of this  Schedule,  to be
      performed by Newco as TEL's  sub-contractor  or by TEL on behalf of Newco,
      such  performance  is at the risk and cost of Newco and any loss and costs
      in relation  thereto  shall be offset  against any amounts to be accounted
      for to Newco  pursuant to paragraph 6. To the extent that any loss or Cost
      exceeds any such amount to be accounted for to Newco pursuant to paragraph
      6, Newco shall  indemnify  TEL against or reimburse TEL for any payment in
      respect thereof.

8.    Insofar as the provisions of this Schedule  provide for TEL to perform any
      Relevant  Agreement or otherwise  assume any  obligation,  Newco agrees to
      lease or licence  (so far as Newco is able to grant the same) to TEL,  for
      the period  during  which any such  obligation  exists as provided in this
      Schedule, any Business Assets acquired by Newco pursuant to this Agreement
      and necessary for the purposes of such performance.  The consideration for
      any  such  lease  or  licence  shall be TEL's  agreement  to  perform  any
      obligations  expressed to be performed by it in this Schedule in favour of
      and for the  account of Newco for any monies or  profits as  described  in
      paragraph  6 above  and so  that  TEL  shall  not be  required  to pay any
      additional amount in respect thereof.

<PAGE>

9.    Newco agrees to make  available  to TEL the  services of any  Transferring
      Employees or any Offer  Employees to enable TEL to perform any obligations
      expressed to be performed by it in this  Schedule:  PROVIDED that any such
      employees  shall continue to be employees of Newco and Newco shall perform
      and observe all the  obligations  of the employer  under or in  connection
      with the  contracts  of  employment  of such  persons  (including  without
      limitation  holiday  entitlement  and pay) and Newco shall  indemnify  TEL
      against or  reimburse  TEL for any payment  required to be made or made by
      TEL to any such Transferring Employees or Offer Employees.

10.   Upon any such consent as is referred to in paragraph 1 being obtained,  as
      a result of which any  assignment,  sub-lease or any other transfer of the
      benefit of any Relevant Business Asset to Newco or the assumption by Newco
      of any Newco  Liability  would  not  constitute  a breach of any  Relevant
      Agreement  of TEL with or to the third party from whom any such consent is
      obtained, such Relevant Business Asset shall pursuant to this paragraph be
      assigned,  sub-leased or the benefit thereof otherwise vested in Newco, or
      Newco shall assume the Newco Liability, as the case may be on the terms of
      this Agreement and:-

10.1  any lease or licence for any  Business  Assets  referred to in paragraph 8
      shall thereupon automatically terminate; and

10.2  insofar as the services of any  Transferring  Employees or Offer Employees
      have been made  available to TEL as provided in paragraph 9 in  connection
      with  such  Relevant   Business  Asset,   such  services  shall  thereupon
      automatically  cease to be made  available in any case,  without  Costs to
      TEL, and the provisions of this Schedule shall cease to apply with respect
      thereto.

11.   Without prejudice to the generality of the foregoing,  TEL shall,  without
      incurring any Cost,  take such actions as Newco may reasonably  request to
      procure that suppliers  under the Supplier  Contracts and customers  under
      the  Materials   Customer   Contracts   unconditionally   consent  to  the
      substitution  of Newco as a party  thereto  with effect from the  Transfer
      Time but,  in any case where such  consent  is  refused or  otherwise  not
      obtained, prior thereto:-

11.1  TEL shall  receive any goods  delivered to it by the supplier as agent for
      Newco and at Newco's  cost,  taking  reasonable  care,  shall deliver such
      goods to such address of Newco as Newco may specify; and

11.2  Newco shall put TEL in funds to enable TEL to pay in due time the supplier
      in respect thereof.

12.   If, on or before 6 weeks after the  Transfer  Time,  or such later date as
      TEL and Newco may agree,  any  consent  or  agreement  of any third  party
      referred to in paragraph 1 has not been  obtained or if, at any time,  the
      benefit  of any  Relevant  Business  Asset  cannot  be  vested in Newco or
      otherwise  dealt with by Newco,  TEL and Newco shall consider what action,
      if any, is to be taken in relation to the Relevant Business Asset.

<PAGE>

13.   TEL shall not be obliged to take any action pursuant to this Schedule 7 if
      such action  could not be lawfully  undertaken  by TEL, or would result in
      any breach of any  agreement  to which TEL is a party which  breach  would
      entitle the other  party  thereto to  terminate  such  agreement  or would
      result in TEL incurring any Costs of a material amount against which Newco
      has not agreed to indemnify it pursuant to this Agreement or otherwise. In
      so far as,  pursuant  to this  Agreement,  TEL is a trustee of, or acts as
      agent  for  Newco,  TEL  shall  act  with  such  care  and  skill as might
      reasonably  have  been  expected  of TEL in the  conduct  of the  Business
      assuming the sale and  purchase of the  Business  and the Business  Assets
      pursuant to this Agreement had not occurred but,  subject  thereto,  shall
      not have any duties or  responsibility to Newco in respect of so acting or
      have any  liability  to Newco  except to the  extent  that it is guilty of
      wilful  default  or of  acting  otherwise  than  with the  care and  skill
      referred to in this paragraph.

3.    CONDUCT OF DISPUTES

3.1   This  paragraph  applies  as to the  conduct  of any  claim  made  by,  or
      proceedings  instituted or threatened by, any third party,  whether before
      or after the date hereof (including any counter-claim)  ("PROCEEDINGS") in
      relation to any  Debtor,  Materials  Business  Debtor,  Retained  Business
      Claim,  Materials  Business Claim, Newco Liability or TEL Liability by the
      party  (the  "CONDUCTING  PARTY")  specified  by this  Agreement  as being
      entitled to conduct  such  Proceedings.  In any case where this  Agreement
      does  not  specify  which  of  the  parties  is to  have  the  conduct  of
      Proceedings in any particular case,  including in circumstances  where the
      potential  responsibility for any liability the subject of any Proceedings
      has not been  allocated  between the parties,  the party  against whom the
      claim has been made, or proceedings  instituted or threatened,  shall have
      conduct of the Proceedings, or, if the claim has been made, or proceedings
      instituted or threatened, against both parties, TEL shall have the conduct
      of the  Proceedings  and, in either case,  accordingly  be the  Conducting
      Party in respect thereof for the purposes hereof.

3.2   The  Conducting  Party  shall  inform the party not having  conduct of the
      Proceedings (the "OTHER PARTY") promptly of all developments regarding the
      Proceedings,  shall consult it and have reasonable regard to its interests
      before  taking any  significant  step in relation to the  Proceedings  and
      shall not settle the  Proceedings  without the consent of the Other Party,
      such consent not to be  unreasonably  withheld or delayed.  The Conducting
      Party  shall  conduct  any  Proceedings  with  reasonable   diligence  and
      competence.  The  Other  Party  shall  render  all  assistance  reasonably
      required in connection with the Proceedings by the Conducting  Party,  and
      shall be  entitled  to payment in respect of that  assistance  only in the
      event that the  assistance it renders is  significantly  greater in extent
      than that provided by the Conducting Party.

<PAGE>

3.3   The Conducting Party may instruct legal advisers  reasonably  satisfactory
      to the Other  Party to  represent  any  member of the Other  Party (or any
      member of the Other  Party's  Group in the case of TEL which is a party to
      the Proceedings:  PROVIDED that in any Proceedings where the named parties
      to any such  Proceedings  (including any added  parties)  include both the
      Conducting  Party (or any  member of its Group in the case of TEL) and the
      Other  Party  (or  any  member  of its  Group  in the  case  of  TEL)  and
      representation  of both parties by the same legal  advisers  would not, in
      the opinion of the legal advisers  appointed by the Conducting  Party,  be
      proper due to actual or potential  conflict of interest  between them, the
      Conducting  Party  shall  instruct  separate  legal  advisers   reasonably
      satisfactory  to the Other Party to represent the Other Party (and members
      of its Group) in such  Proceedings and the Conducting  Party shall pay the
      fees and disbursements of such legal advisers.

      those enjoyed immediately prior to the Transfer Time or the termination of
      the employment of any of them on or after the Transfer Time;

5.6   any claim by any  Transferring  Employee  or Offer  Employee  (whether  in

      directives  made  under the  authority  of that  Treaty))  for any  remedy
      including, without limitation, in respect of unfair dismissal, redundancy,
      equal pay, sex, race or disability discrimination; or

5.7   any  claim  by any  employee  representatives,  trade  union  or  affected
      employee that there has been a failure to comply with any  requirement  of
      Regulation  10 of the Transfer  Regulations,  any failure to inform and/or
      consult  employees  imposed by any  collective  agreement,  European Works
      Council Agreement or other employee representative agreement.

6.    Newco  shall,  as from the  Transfer  Time,  perform  and  observe all the
      obligations  of TEL as  employer,  or host  (where the  employee  has been
      seconded to TEL but is not employed by TEL) under or in connection with:-

6.1   the contracts of employment of the Offer Employees; or

6.2   any contract relating to their secondment to TEL; or

      TEL  indemnified  against each and every  action,  proceeding,  liability,
      Costs,  claim,  loss, and demands  arising from Newco's failure to perform

9.1   the  Transferring  Employees  and Offer  Employees  will receive and enjoy
      contractual  remuneration  and benefits  (including  retirement  benefits)

      contractual remuneration and benefits at the Transfer Time;

9.2   it will not make any unilateral  material change to the contractual  terms
      and conditions of employment of the  Transferring  Employees and the Offer
      Employees,  (which includes those terms contained in a letter to employees

1.5   CALCULATION OF THE FINAL CONSIDERATION

      In relation to this Agreement:

      1.5.1 the  Final   Consideration  for  the  Business  Assets  ("THE  FINAL
            CONSIDERATION") shall be determined by the following formula:-

            Final  Consideration = US$  118,410,000  minus [U.S. $ EQUIVALENT OF
            GBP3,950,000 (REPRESENTING THE NET WORKING CAPITAL AS AT 28 FEBRUARY
            1998) CONVERTED INTO U.S. $ IN ACCORDANCE WITH PARAGRAPH 1.4 OF THIS
            SCHEDULE] plus Actual Net Working Capital.

      1.5.2 After  the Newco  Completion  Date TEL  shall  prepare a  completion
            statement  as at the Newco  Completion  Date which  shall  contain a
            statement of the Final  Consideration  in accordance  with paragraph
            1.5.1 above and a schedule of the Actual Net Working  Capital  based
            on TEL's calculations (the "FINAL COMPLETION STATEMENT").  The Final
            Completion Statement shall be prepared using ICI's normal accounting
            policies  and   practices  as  set  out  or  referred  to  in  ICI's
            Controller's Manuals and prepared as at the Newco Completion Date on
            a basis consistent with that adopted by TEL for the preparation of A
            Forms prior to the  Hivedown  and shall be submitted by TEL to ICI's
            Auditors for review.

1.6   Within 50 days of the Newco  Completion  Date,  TEL shall  issue the Final
      Completion  Statement to Newco  together  with a copy of a report by ICI's
      Auditors addressed to TEL and substantially in the form set out in Annex 4
      to the effect that the Final  Completion  Statement  has been  prepared in
      accordance  with this  Schedule.  Although it is TEL's  responsibility  to
      prepare the Final Completion Statement, TEL will require the assistance of
      the employees of Newco and its  Affiliates  to fulfil this  responsibility
      and Newco shall  ensure such  assistance  is provided  promptly  and at no
      charge.  Immediately  after  delivery of the Final  Completion  Statement,
      Newco's  Auditors  shall  have the  right to review  the Final  Completion
      Statement  and  ICI's  Auditors  working  papers  relating  to  the  Final
      Completion  Statement.  Within 30 days of  delivery  to Newco of the Final
      Completion  Statement and ICI's Auditors report (each of which shall be in
      English) to Newco's designated location, Newco shall give notice to TEL in
      writing of any item or items in the Final  Completion  Statement  which it
      wishes to dispute  and the basis on which it  disputes  that item or those
      items  and the  changes  to the Final  Completion  Statement  which  Newco
      believes  should  be made  and the  parties  shall  use  their  reasonable
      endeavours  to resolve that  dispute.  Any items in respect of which Newco
      does not give such notice  will be deemed to have been  accepted by Newco.
      Any written  resolution  reached by the parties on any disputed item shall
      be final, conclusive and binding on the parties.

<PAGE>

1.7   If the parties  agree the Final  Completion  Statement  then any adjusting
      payments  referred to in  paragraph  1.9 below shall be made by the paying
      party within 7 days of being agreed by the parties.

1.8   If the  parties  fail to  agree on any  element  of the  Final  Completion
      Statement within 24 days after Newco has given notice in writing to TEL of
      any  item(s)  in the Final  Completion  Statement  which  Newco  wishes to
      dispute (in  accordance  with paragraph 1.6 above) then any agreed amounts
      shall be paid in accordance  with the preceding  paragraph and any dispute
      may be referred by either party for final determination in accordance with
      Clause 14 of this Agreement and any amounts  thereby found to be due shall
      be paid by the  relevant  party not later  than 7 days  after  such  final
      determination.

1.9   When  the  Final  Consideration  is  agreed  or  otherwise  determined  in
      accordance  with the three  preceding  paragraphs the following  adjusting
      payments shall be made:-

      1.9.1 an  amount  equal  to  the  difference  between  (i)  the  Estimated
            Consideration   (namely   US$   118,410,000)   and  (ii)  the  Final
            Consideration; and

      1.9.2 interest  (compounded monthly) at the Interest Rate on the amount in
            paragraph 1.9.1 above from the Newco  Completion Date to the date of
            payment, calculated on a day to day basis;

      which  shall  be  paid  by TEL to  Newco  (or  vice  versa,  if the  Final
      Consideration exceeds the Estimated Consideration).

1.10  In this  Schedule,  references to lines of A-Forms have been chosen by TEL
      and are believed in good faith to  correspond to the matters to which they
      refer.  If,  however,  that  reference  when  compared  to the  matter  it
      describes or refers to is incorrect  then there shall be  substituted  for
      that line reference  another line reference (if any) which  corresponds to
      the matter described or referred to.

       4  PURCHASER'S WARRANTIES AND UNDERTAKINGS

     4.1 The Purchaser warrants to the Seller that:

          4.1.1   it  (and  each  of  its   Affiliates,   in   respect   of  the
                  Implementation  Agreements to which such Affiliate is a party)
                  has the  requisite  power and  authority  to enter into and to
                  perform this agreement and such Implementation Agreements;

          4.1.2   it  (and  each  of  its   Affiliates,   in   respect   of  the

          4.1.3   this agreement and the  Implementation  Agreements  constitute

                      a party or by which it is bound; and

       5  SELLER'S WARRANTIES AND UNDERTAKINGS

     5.1  The Seller warrants to the Purchaser that, save as otherwise stated in
          this  agreement  and subject to all matters and  circumstances  fairly
          disclosed in the Grimsby Disclosure Letter, each of the statements set
          out in Schedule 3 to this  agreement  (the  "WARRANTIES")  is true and
          accurate as at the date of this agreement and the Seller  acknowledges
          that the  Purchaser  has entered into this  agreement in reliance upon
          the Warranties.

     5.2  Each of the  Warranties  shall  be  separate  and  independent  and no
          Warranty shall limit the scope or  construction  of any other Warranty
          or any other provision of this agreement.

<PAGE>

     5.3 The Purchaser acknowledges and agrees that:

          5.3.1   except for the Warranties,  no statement,  promise or forecast
                  made  by or on  behalf  of the  Seller  or any  member  of the
                  Seller's  Group or any  member  of the ICI  Group may form the
                  basis of, or be pleaded in connection  with,  any claim by the
                  Purchaser  under or in connection  with this  agreement or the
                  Implementation  Agreements  (save  as may  be  set  out in the
                  Implementation Agreements); and

          5.3.2   any claim by the Purchaser or any person  deriving  title from
                  it in connection  with the Warranties  shall be subject to the
                  following provisions of this Clause.

     5.4  The  liability  of the Seller  under or in respect of a Claim shall be
          governed by the terms of this Clause 5 and shall be limited in respect
          of any liability which is contingent,  unless and until such liability
          becomes an actual liability and is due and payable,  provided that the
          Purchaser  shall not be  prohibited  from  bringing such claim pending
          such liability becoming due and payable.

     5.5 It is hereby  agreed that the Seller  shall have no  liability  for any
         Claim:

          5.5.1   unless  the  amount  of such  Claim  exceeds  US$100,000  (the
                  "QUALIFYING Amount"); and

          5.5.2   until and to the extent only that the aggregate  liability for
                  all  Claims   exceeding  the   Qualifying   Amount   (notified
                  previously  or at the same  time)  exceeds  US$5,300,000  (the
                  "THRESHOLD AMOUNT").

          For  the  avoidance  of  doubt,  notwithstanding  that  the  aggregate
          liability for Claims  exceeding  the  Qualifying  Amount  ("QUALIFYING
          CLAIMS") of the Seller has exceeded the Threshold  Amount,  the Seller
          shall be liable solely for that excess.

     5.6  It is hereby agreed that the maximum aggregate liability of the Seller
          in respect of all Claims shall under no  circumstances  exceed (to the
          extent that the relevant  Claim has been  brought by the  Purchaser in
          accordance  with the terms of this agreement  within the relevant time
          period) an amount to be determined as follows (the "CAP"):

          5.6.1   in respect of all Claims  notified  to the Seller  pursuant to
                  this agreement in the period commencing on the Completion Date
                  up to but not including the third anniversary thereof, the Cap
                  shall be US$63,152,000;

          5.6.2   on the  third  anniversary  of  the  Completion  Date  the Cap
                  shall  reduce to US$44,206,400;

          5.6.3   on  the  fourth  and  each   subsequent   anniversary  of  the
                  Completion  Date  the  Cap  shall  reduce  (but  so  that  the
                  applicable anniversary date for determining whether a Claim is
                  subject to a Cap reduction as aforesaid  shall be by reference
                  to the date upon  which the Claim is  notified  to the  Seller
                  pursuant  to  this  agreement  and  not the  date  upon  which
                  liability  thereunder is accepted or adjudicated) by an amount
                  of  US$6,315,200  such  that on the tenth  anniversary  of the
                  Completion Date it is completely extinguished.

     5.7  Subject to sub-Clause 5.14, the Seller shall have no liability for any
          Claims notified by the Purchaser on or after the tenth  anniversary of
          the Completion Date.

     5.8  For the avoidance of doubt, in no  circumstances  whatsoever shall the
          maximum  aggregate  liability  of the  Seller in respect of all Claims
          exceed US$63,152,000.

     5.9 The Purchaser acknowledges and agrees that:

          5.9.1   no  liability  shall  attach  to the  Seller  by reason of any
                  breach of any of the  Warranties  or other  provisions of this
                  agreement or the Implementation  Agreements to the extent that
                  the loss has been recovered by the Purchaser  under Schedule 6
                  or  any  other   term  of  this   agreement   or  any  of  the
                  Implementation  Agreements and  accordingly  the Purchaser may
                  only recover once in respect of the same loss; and

<PAGE>

          5.9.2   in  calculating  the liability of the Seller for any breach of
                  the Warranties there shall be taken into account the amount by
                  which any Taxation  for which the  Purchaser or the Company is
                  now or in the future  accountable  or liable to be assessed is
                  reduced or  extinguished as a result of the matter giving rise
                  to such liability.

    5.10 The Purchaser shall not be entitled to make any Claim:

          5.10.1  to the extent  that the Claim  arises as a result  only of any
                  change after Completion in the accounting bases upon which the
                  Company values its assets or computes its profits or arises as
                  a result of the  taxation  or  accounting  policies,  bases or
                  practices of the Purchaser being different to those adopted or
                  used in preparing the Grimsby Financial Information; or

          5.10.2  to the extent that the matter which  constitutes the Claim was
                  specifically consented to in writing by the Purchaser.

    5.11  The  Purchaser  shall not be  entitled  to rescind or  terminate  this
          agreement after Completion in any circumstances  provided that nothing
          in this sub-Clause shall exclude or limit any liability for fraud.

    5.12  Save as otherwise provided in this agreement,  the Seller shall not be
          liable in  respect  of any Claim as a result  of any  legislation  not
          brought into force at the date of this agreement or as a result of any
          change  in or repeal of  legislation  hereafter  or as a result of the
          introduction  or cessation of or change in the  published  practice of
          any taxation authority after the date of this agreement.

    5.13  The  Purchaser  shall not be  entitled to make any claim in respect of
          any  breach or alleged  breach of the  Warranties  or the  indemnities
          contained  in this  agreement  or under  any other  provision  of this
          agreement to the extent that:

          5.13.1  the facts,  matters or  circumstances  giving rise thereto (in
                  respect of which any such claim or alleged  claim arises) have
                  been fairly disclosed in the Grimsby Disclosure Letter; or

          5.13.2  such claim arises or is incurred as a result of any  voluntary
                  act or  omission  of the  Purchaser  or any  Affiliate  of the
                  Purchaser after the date of this agreement other than any such
                  act or omission which is in the ordinary course of business or
                  is  required  by  law  or is  pursuant  to a  legally  binding
                  commitment of the Company or any member of the Seller's  Group
                  created or entered into before Completion; or

          5.13.3  allowance,  provision  or reserve  in  respect of the  subject
                  matter of such claim has been made or has otherwise been taken
                  into account or reflected in the mechanics for the calculation
                  of the Final Hivedown  Consideration or the Actual Net Working
                  Capital.

    5.14  The  Purchaser  shall take all  reasonable  steps to mitigate any loss
          which  may  give  rise  to a Claim  including,  without  limiting  the
          generality of the foregoing,  the making of a claim which is available
          to the  Purchaser  or its  Affiliates  under any  available  insurance
          policy. It is agreed that:

          5.14.1  no Claim  by the  Purchaser  in  respect  of a  breach  of the
                  Warranties shall be enforceable  unless written notice thereof
                  (including  all  material   details  thereof  then  reasonably
                  available to the Purchaser) has been given by the Purchaser to
                  the  Seller  as  soon  as  reasonably  practicable  after  the
                  Purchaser  has  become  aware of the facts  and  circumstances
                  giving  rise to such  claim  and  their  implications  for the
                  purposes of this  agreement and unless such written notice has
                  been  duly  served  on the  Seller  within  24  months  of the
                  Completion Date;
<PAGE>


          5.14.2  no other Claims by the Purchaser  shall be enforceable  unless
                  written notice thereof (including all material details thereof
                  or  relating   thereto  then   reasonably   available  to  the
                  Purchaser)  has been given by the  Purchaser to the Seller (in
                  accordance  with  the  terms  of  this  agreement)  as soon as
                  reasonably practicable after the Purchaser has become aware of
                  the facts and circumstances giving rise to the claim and their
                  implications for the purpose of this agreement;

          Provided  however that the Purchaser  shall be able to bring any Claim
          against the Seller  without  complying  with the terms of  sub-Clauses
          5.14.1  and  5.14.2  hereof  to the  extent  that the  Seller  has not
          suffered  prejudice  as a  result  of any such  non-compliance  by the
          Purchaser.

    5.15  If any claim is made  against the Company the subject  matter of which
          might  also  reasonably  be  expected  to give  rise to a  Claim,  but
          excluding  matters provided for in Schedule 6 in relation to which the
          specific provisions set out in Schedule 6 shall apply:

          5.15.1  the Purchaser  shall, if so requested by the Seller,  take all
                  steps which are  necessary and  reasonable  to avoid,  resist,
                  appeal,   compromise   or  defend   any  such  claim  and  any
                  adjudication  in respect thereof (but subject in any such case
                  to the Purchaser  being  indemnified by the Seller against all
                  costs and expenses  which may  reasonably  and  necessarily be
                  incurred in connection therewith) and the Seller shall, at its
                  request,  be allowed to conduct any negotiations,  proceedings
                  or appeals incidental thereto;

          5.15.2  the Seller shall raise no objection to the Purchaser attending
                  (and,  where  the  rights  of the  Purchaser  are,  or may be,
                  detrimentally  affected) being separately legally  represented
                  (at its own  expense)  and,  where  appropriate,  heard at any
                  negotiations,  proceedings  or  appeals  which the  Seller has
                  taken conduct of pursuant to  sub-Clause  5.15.1 above and the
                  Purchaser  shall  be  consulted  by the  Seller  prior  to any
                  compromise, settlement or admission of liability being made by
                  the Seller at such negotiation, proceedings or appeals; and

          5.15.3  the  Purchaser   shall  at  all  reasonable   times  and  upon
                  reasonable  prior  notice  allow  the  Seller  and its  agents
                  reasonable  access to all relevant  properties  of the Grimsby
                  Business,  and access to,  with the right to inspect  and take
                  copies of, all relevant books and records and Grimsby Business
                  Data of the  Grimsby  Business  (as then  carried  on) subject
                  always to keeping the same confidential  other than in respect
                  of necessary  disclosures  in  connection  with such action or
                  claim  which  disclosures  shall only be made and then only in
                  compliance with sub-Clause  5.15.4,  if required by law or the
                  procedures  of any court or  tribunal  or  otherwise  with the
                  prior written consent of the Purchaser (such consent not to be
                  unreasonably withheld or delayed);

          5.15.4  if  the  Seller  or  its  agents  become   legally   compelled
                  (including   by   deposition,   interrogatory,   request   for
                  documents,  subpoena,  civil  investigative  demand or similar
                  process) to disclose any of the information, records, or other
                  material  referred  to in  sub-Clause  5.15.3,  the  party  so
                  compelled  shall  provide  the  Purchaser  with  prompt  prior
                  written  notice of such  requirement so that the Purchaser may
                  seek a protective order or other appropriate remedy. So far as
                  it is legally able so to do, the Seller agrees to cooperate in
                  the Purchaser's  efforts to obtain a protective order or other
                  reasonable  assurance  that  confidential  treatment  shall be
                  accorded any such  information.  If such  protective  order or
                  other remedy is not obtained, the party so compelled agrees to
                  disclose  only that portion of the  information,  records,  or
                  other  material  which it is  advised  by  opinion  of outside
                  counsel is legally  required to be  disclosed  and to take all
                  reasonable  steps  to  preserve  the  confidentiality  of  the
                  information,  records,  or other material  referred to in this
                  sub-Clause 5.15.4.

<PAGE>

    5.16  If the Seller pays to the Purchaser any amount under this agreement in
          respect  of any  Claim and the  Purchaser  or the  Company  is able to
          recover  any sum from any  third  party  (including  any  insurer)  in
          respect of that Claim, the Purchaser shall, and shall procure that the
          Company shall,  use all  reasonable  endeavours to so recover any such
          sum and shall  repay to the Seller so much of the  amount  paid by the
          Seller  as is  equal  to any sum  recovered,  after  allowing  for the
          reasonable  costs  and  expenses  of  the  Purchaser  or  the  Company
          reasonably  incurred in connection  therewith,  provided  that, in the
          event that the Purchaser or the Company elects not to recover any such
          sum from such third party, the Seller shall be entitled at its cost to
          require  that  the  Purchaser  or the  Company  assign  such  right of
          recovery to the Seller.  Furthermore,  if any liability on the part of
          the Seller  hereunder  which  results  in a payment  being made by the
          Seller to the  Purchaser  gives  rise to any  corresponding  saving or
          rebate to the  Purchaser or the Company  (including  any tax saving or
          rebate) then the value of such  corresponding  saving or rebate to the
          Purchaser  or the Company  shall be set against the  liability  of the
          Seller hereunder.

    5.17  Any  payment  by  the  Seller  made  to  the  Purchaser  (or  for  the
          Purchaser's  benefit) in respect of any liability under this agreement
          for  breach of the  Warranties  or  otherwise  shall be deemed to be a
          reduction  in the  consideration  payable  hereunder in respect of the
          Sale Shares.

    5.18  No party  hereto shall be entitled to set off any amounts due to it by
          any other party  (whether  under this  agreement,  the  Implementation
          Agreements or otherwise)  against sums owing (or claimed by such other
          party to be  owing)  under the terms of this  agreement  (whether  for
          breach of the Warranties or otherwise).

    5.19  The provisions of this Clause 5 shall have effect  notwithstanding any
          other provisions of this agreement.

    5.20  The parties are of the view that the  provisions of Section 343 of the
          Income and Corporation  Taxes Act 1988 and Section 171 of the Taxation
          of  Chargeable  Gains Act 1992 will not apply in  connection  with the
          sale and purchase of the Grimsby  Assets under the Hivedown  Agreement
          and the Seller agrees and undertakes to prepare and submit tax returns
          on the basis  that the said  Sections  343 and 171 are not  applicable
          (the "AGREED  BASIS").  Subject to  compliance  by the Seller with the
          foregoing  provisions  of this Clause  5.20,  the Seller shall have no
          liability to the Purchaser if, notwithstanding such compliance,  Newco
          fails to obtain capital allowances or allowable  expenditure under the
          said Section 343 in a manner consistent with the Agreed Basis.


       6  SELLER'S INDEMNITY

     6.1  The Seller undertakes to indemnify and keep indemnified the Purchaser,
          its Affiliates and the Company (the "INDEMNIFIED PARTIES") against all
          claims  by third  parties  (other  than any  subsequent  purchaser  or
          purchasers  of either the Sale Shares or the business or assets of the
          Company  and their  successors  in title or  assigns)  giving  rise to
          losses, costs, liabilities,  proceedings, claims, demands and expenses
          (including  reasonable  legal fees) other than  liabilities  expressly
          assumed  by  the   Purchaser   pursuant  to  this   agreement  or  the
          Implementation  Agreements or to the extent that such liabilities have
          been taken into account in the  mechanics for the  calculation  of the
          Final  Hivedown  Consideration  or  the  Actual  Net  Working  Capital
          (together,  "LIABILITIES")  which  may  be  incurred  by  any  of  the
          Indemnified  Parties or to which any of the  Indemnified  Parties  may
          become  subject  and which arise as a result of the  operation  of the
          Grimsby Business by the Company prior to Completion  (unless the claim
          made by the third  party  giving  rise to the  Liabilities  was fairly
          disclosed in the Grimsby Disclosure Letter), including:

<PAGE>

          6.1.1   Liabilities  arising as a result of the failure by the Company
                  to comply with relevant and legally  enforceable  corporate or
                  other laws,  rules,  ordinances or regulations with respect to
                  the operations of the Grimsby Business prior to Completion

          6.1.2   any breach of contract, tort, product liability or other claim
                  arising from, or with respect to, the operation of the Grimsby
                  Business  prior to Completion and asserted by any third party;
                  and

          6.1.3   any   suit,   action,   arbitration,    charge,   governmental
                  investigation,  claim,  litigation or  proceedings  pending or
                  threatened at Completion and affecting the Grimsby Business or
                  the Company.

          For the avoidance of doubt,  the indemnity  contained in this Clause 6
          shall  not  apply  to (i) any  liability  to  Taxation;  or  (ii)  any
          Environmental Liabilities, any failure or omission to obtain or comply
          with Environmental  Authorisations,  any failure or omission to comply
          with any  Environmental  Laws or any claim by any person in respect of
          any  matter  concerning  the  Environment.  All  definitions  in  this
          sub-Clause (ii) are as defined in Schedule 6.

     6.2  The  Purchaser  agrees to give the Seller notice of any and all claims
          asserted against any Indemnified Party for which indemnification is or
          may be sought  under this Clause 6. Such notice shall be given as soon
          as the Purchaser becomes aware that it has or may have a claim against
          the Seller  under this Clause 6. Failure to give such notice shall not
          abrogate or diminish the Seller's  obligation under this Clause if the
          Seller has or receives knowledge of the existence of any such claim by
          any other means or if such  failure  does not  prejudice  the Seller's
          ability to defend such a claim.

     6.3  In  any  litigation,   administrative   proceedings,   negotiation  or
          arbitration  pertaining  to any  claim for  which  indemnification  is
          sought  pursuant  to  sub-Clause  6.1 above the Seller  shall have the
          right to select legal counsel to represent any  Indemnified  Party and
          otherwise  to control such  litigation,  proceedings,  negotiation  or
          arbitration.   If  the  Seller  elects  to  control  such  litigation,
          proceeding,  negotiation or  arbitration,  the Purchaser shall have at
          all times the right  fully to  participate  in the  defence at its own
          expense.  If the Seller shall  within a  reasonable  time after notice
          unreasonably  fail to defend the claim,  the Purchaser  shall have the
          right  but not the  obligation  to  undertake  the  defence  of and to
          compromise or settle the claim or any other matter on behalf,  for the
          account,  and at the risk, of the Seller provided that such settlement
          shall be  negotiated  and entered into by the Purchaser on a bona fide
          basis and shall not  exceed  the sum  claimed.  In the event  that the
          claim is one that  cannot  by its  nature  be  defended  solely by the
          Seller with  reference to the personnel and  information  available to
          the Seller,  the Purchaser  shall make available all  information  and
          assistance  as the  Seller  may  reasonably  request  at the  Seller's
          expense.

     6.4  Notwithstanding the foregoing provisions, should the subject matter of
          any litigation, proceeding, negotiation or arbitration include a claim
          against any Indemnified Party seeking injunctive relief, the Purchaser
          shall have the right to take  exclusive  control of the defence of the
          entire proceedings.

                      Company and to the effect that there are no  circumstances
                      connected  with  their  resignation  which  they  consider
                      should be  brought to the  notice of the  shareholders  or

          and   benefits   (including   retirement   benefits)   which,   judged

          terms and conditions of employment with the Grimsby  Employees  (which

          1991 from the Seller) without prior consultation where required by any

          sale of any copperas product.


      12  ANNOUNCEMENTS

      15  GENERAL

    15.1  Each of the  obligations,  warranties and undertakings set out in this

          force after Completion.

    15.2  Unless otherwise  expressly stated, all claims made and payments to be

          the Seller at the TEL  Account or at such other  account as the Seller
          may  notify  to the  Purchaser  and to the  Purchaser  in  immediately

          deductions or withholdings  of any kind,  except for those required by
          law and,  if any  deduction  or  withholding  must be made by law,  an
          additional  amount will be paid which is  necessary to ensure that the
          recipient  receives a net  amount  equal to the full  amount  which it
          would have received if the payment had been made without the deduction
          or withholding.

    15.4  None of the rights or obligations under this agreement may be assigned
          or  transferred  without the  written  consent of the other party (the

          the obligations) to an Affiliate of the assigning party provided that:

          15.4.1  such assignment  shall only be permitted if the assignment has
                  no adverse effect on the Non-assigning Party;

          15.4.2  if the Affiliate to which the rights have been assigned ceases
                  to be an Affiliate of the  assigning  party,  the rights which
                  have been  transferred  shall be  re-transferred  to the party
                  which originally assigned those rights or to another Affiliate
                  of that original assigning party; and

          15.4.3  it shall be a condition of any such assignment that reasonable
                  notice is given in writing to the  Non-assigning  Party of the
                  proposal  to assign  (identifying  the rights  proposed  to be
                  assigned, the identity of the proposed assignee and such other
                  details  relating  thereto  as  the  Non-assigning  Party  may
                  reasonably require).

    15.5  Save as otherwise provided in this agreement, each party shall pay the
          costs and expenses  incurred by it and its  Affiliates  in  connection
          with the entering into and completion of this agreement.

          and documents,  procuring the convening of all meetings, the giving of

          (3)     The Company  does not have any place of business or  permanent

     A.5  OWNERSHIP OF GRIMSBY ASSETS

          (1)     Except  for the  Excluded  Assets  and those  assets  that are
                  leased (as  described  in the Grimsby  Disclosure  Letter) the
                  Company has full legal and beneficial title to all the Grimsby
                  Assets reflected in the Grimsby  Financial  Information  (save
                  for  current   assets  and  fixed   assets   worth  less  than
                  US$100,000,  both as defined  for the  purposes of the Grimsby
                  Financial  Information,  disposed  of by  the  Company  in the
                  ordinary course of its business since 28 February 1998) and to
                  all Grimsby  Assets  acquired by the Company since 28 February
                  1998.

          (2)     None of the  Grimsby  Assets  is  subject  to any  encumbrance
                  (including without limitation any debenture, mortgage, charge,
                  lien,  deposit  by way of  security,  bill of sale,  option or
                  right of  preemption)  except those that arise in the ordinary
                  course of business and do not have a material  adverse  effect
                  on the  Grimsby  Business.  All  significant  items of Grimsby
                  Plant  and  Equipment   have  been  regularly  and  adequately
                  maintained where such maintenance is normally required and are
                  in reasonable working order having regard to their age and use
                  and taken as a whole are  capable  of  operating  the  Grimsby
                  Business fully and effectively as previously carried on by the
                  Company.

          (3)     Save for fluctuations and variations in the Grimsby Stocks due
                  to  normal  business  factors  including  without   limitation
                  production  schedules  and market demand  (including  seasonal
                  factors  affecting  the same) the Grimsby  Stocks in aggregate
                  comprise broadly the same mix of products as has been required
                  and has been maintained at levels sufficient to meet the level
                  of sales of the Grimsby  Business for the last four  quarters.
                  The Grimsby  Stocks are owned by the Company free and clear of
                  all liens,  claims,  charges and  encumbrances  other than any
                  such interests arising in the ordinary course of business. The
                  Grimsby Stocks are located at the Grimsby Properties.

          (4)     The  Company  owns or has the  right  to use all the  property
                  rights and assets  necessary for the Company to carry on fully
                  and effectively  the Grimsby  Business in the manner in and to
                  the extent to which it is presently conducted.

<PAGE>

                  Business Data) contains in all material respects bona fide and
                  accurate records of all matters  customarily or required to be
                  dealt  with  therein.   The  Grimsby  Business  Data  and  the
                  Company's  information,  and the  means of  access to them are
                  exclusively  owned by it and under its  direct  control or are
                  under its authority.

          (6)     The Grimsby  Disclosure Letter contains details of the current
                  insurance  arrangements  applicable  to the Grimsby  Business.
                  Those  arrangements are in full force and effect, all premiums
                  have been duly paid and so far as the Seller is aware, nothing
                  has been  done or  omitted  to be done  which  would  make any
                  policy of insurance of the Company void or voidable.  There is
                  no material claim outstanding under any such arrangement.


     A.6  COMPLIANCE WITH STATUTES

          In  relation  to  the  Grimsby   Business,   the  Company  is  not  in
          contravention  of any  statute,  order  or  regulation  of the  United
          Kingdom or any relevant foreign country,  including but not limited to
          the Foreign Corrupt  Practices Act and the United States  anti-boycott
          regulations,  which is likely to result in a fine or  penalty or which
          would have a material adverse effect on the Grimsby Business. There is
          no order,  decree or judgment of any court or  governmental  agency of
          the United  Kingdom or any  foreign  country  outstanding  against the
          Company in relation to the Grimsby Business.


     A.7  LICENCES AND CONSENTS

          In relation to the  operation  of the  Grimsby  Business  prior to the
          Transfer Time by the Seller, the Grimsby Business had all governmental
          authorisations  licences and consents necessary to own and operate the
          Grimsby  Assets and to carry on the Grimsby  Business in the manner in
          which such business was carried on. All such authorisations,  licences
          and consents were valid and  subsisting  and were complied with in all
          material respects.  The Seller has paid all fees due under the same. A
          list of material  Permits  relating to the Grimsby  Business  has been
          disclosed and identified in the Grimsby Disclosure Letter.


     A.8  LITIGATION

          (1)     Except as  disclosed  in the Grimsby  Disclosure  Letter,  the
                  Company  is not  engaged  in  any  litigation  or  arbitration
                  proceedings except as plaintiff for collection of debts in the
                  ordinary  course of  business  which is likely to involve  the
                  Company  claiming  or paying sums in excess of  US$100,000  or
                  which  otherwise will have a material  effect on the operation
                  of the Company and the Grimsby  Business and there are no such
                  proceedings  pending  and no  letter  before  action  has been
                  received  by the  Company  and so far as the  Seller  is aware
                  there   are  no  facts   likely  to  give  rise  to  any  such
                  proceedings.   The  Seller  has   disclosed   in  the  Grimsby
                  Disclosure  Letter a list (which is complete  and  accurate in
                  all material respects) which includes a general description of
                  each pending law suit, claim,  including customer  complaints,
                  administrative  proceedings,  arbitration,  labour  dispute or
                  governmental  investigation or inspection to which the Company
                  is a party or involves the  operation of the Grimsby  Business
                  and which is likely to involve the Company  claiming or paying
                  sums in excess of  US$100,000.  The  Seller has  disclosed  in
                  general terms all material  (individually or in the aggregate)
                  product  liability  claims  received  by the Company or by the
                  Seller  during the last 3 years.  There are no orders  decrees

                  In relation to the Grimsby Business:

                  (a) Prior  to the  Transfer  Time,  the  Seller  had  lawfully
                      obtained all  Environmental  Authorisations  and each such
                      authorisation  at such time was in full  force and  effect
                      and the Seller had complied at all times therewith and the
                      Company,    having   obtained   all   such   Environmental
                      Authorisations  (on the same terms and subject to the same
                      conditions  as those held by the Seller),  will be able to
                      continue  to comply in the future with all  conditions  of
                      such authorisations.

                  (b) No works or costs  are or will be  necessary  to obtain or
                      secure   compliance   with  or   maintain   any   existing
                      Environmental   Authorisations   or  their  conditions  or
                      otherwise to comply with Environmental Laws.

                  (c) The Company has received no  communication  in any form in
                      respect  of  any  Environmental   Authorisation   varying,
                      modifying in any material respect, revoking, suspending or
                      cancelling   the  same  or   indicating  an  intention  or
                      threatening  so to do and so far as the  Seller  is  aware
                      there are no facts or  circumstances  which may  result in
                      any Environmental Authorisation being so varied, modified,
                      revoked, suspended or which may prejudice their renewal.

                  (d) So far as the Seller is aware all appropriate or necessary
                      action in  connection  with the renewal or extension of an
                      Environmental Authorisation has been taken.

                  (e) The  Company is not  engaged  in and,  so far as Seller is
                      aware,  there  are  no  facts  which  make  it  likely  or
                      desirable  that it  should  be  engaged  in any  appeal in
                      respect  of  any   Environmental   Authorisation   or  any
                      conditions   contained  therein  or  any  refusal  of  any
                      Environmental Authorisation.

                  (f) So far as the  Seller  is  aware  there  is no  reason  to
                      believe that those Environmental Authorisations which have
                      been  applied  for but which have not yet been  granted or
                      are pending will not be granted within a reasonable period
                      of time and on terms which are acceptable in order for the
                      Company to continue its current business operations.

                      any Environmental  Authorisations being varied,  modified,

                  far as the Seller is aware nothing has been done or omitted to
                  be done which  will or may result in the Scheme  ceasing to be

                  accordance  with the  trusts,  powers  and  provisions  of the
                  Scheme  and with due  regard to the  general  requirements  of

          (5)     So far as the Seller is aware, the Company has complied in all
                  material  respects with its  obligations  under the Scheme and
                  all  amounts  due to be  paid  to  the  Scheme  by it and  its
                  employees have been paid.


                                          G. GRIMSBY PROPERTIES

                  and correct. The use of the Grimsby Properties for the purpose
                  stated in Schedule 2 to the Hivedown Agreement  corresponds to
                  the use to  which  it is in fact  put or  (where  the  Grimsby
                  Properties is not presently in use) to the use to which it was
                  last in fact put.

          (3)     The  Company  has a good and  marketable  title to the Grimsby
                  Properties for the estate or interest  stated in Schedule 2 to
                  the Hivedown Agreement,  free from any defects, and has in its
                  possession,  or under its control,  all duly stamped deeds and
                  documents  which are  necessary  to prove title to the Grimsby
                  Properties,  and such title has already been fully  deduced to
                  the Purchaser's Solicitors.

          (4)     The Company does not require the use and is not in  occupation
                  of or  entitled  to any  estate  or  interest  in any  land or

                  exclusive  occupation  of the whole of the Grimsby  Properties
                  and on  completion  shall be in  exclusive  occupation  of the
                  whole of the Grimsby Properties.

          (5) The Grimsby  Properties  are not affected by any of the  following

                      company including, without limitation,  insurance premiums
                      and  other  usual   business   expenses),   whether  of  a

                  condition,  licence or consent other than those referred to in
                  paragraph A.9 above by any competent authority or other person
                  or so far as the Seller is aware any circumstance  which might
                  give rise to such a breach.

          (7)     The Grimsby  Properties are in a good and substantial state of
                  repair and  condition  and fit for the purposes for which they
                  are presently  used and the Company or the Seller has not used
                  in the Grimsby  Properties  any  substances  not in conformity
                  with  relevant  British  or  European  standards  or  codes of
                  practice or which are  generally  known to be  deleterious  to
                  health and safety  and there are no  uncompleted  works of any
                  description  at the  Grimsby  Properties  other  than  routine
                  maintenance.

          (8)     There  are  no  subsisting  allegations  that  the  use of the
                  Grimsby Properties for the purpose stated in Schedule 2, Parts
                  I and II of the Hivedown  Agreement is not the permitted  user

                  without limitation,  legislation  relating to town and country
                  planning  and health and  safety but  excluding  environmental
                  protection) or regulations  made under such  legislation or is
                  not in accordance with the  requirements of the local planning
                  and all other competent  authorities or that any restrictions,
                  conditions  and  covenants  imposed  by or  pursuant  to  such
                  legislation  have  not  been  observed  and  performed  and no
                  agreement  has been  entered  into under  section 106 Town and
                  Country Planning Act 1990 (or any similar statutory provision)
                  in respect of the Grimsby Properties.

          (9)     The  copy  documents   disclosed  and  the  replies  given  by
                  Linklaters  & Paines to the  Purchaser's  Solicitors'  written

                  respect of any properties (other than the Grimsby  Properties)
                  (or any interest therein) whether by privity of contract or by
                  way of guarantee or surety or otherwise.

          (11)    The  Grimsby  Properties  have  the  benefit  of  all  rights,

                  easements  and  consents  are  enjoyed  on terms  which do not

          (12)    There  are no  outstanding  liabilities  to make  payments  in
                  respect of rates, water charges,  or any other charges payable

                  or discounted any debt or agreed to do so.

          (3)     All of  the  debts  which  will  be  reflected  in  the  Final
                  Completion Statement (as defined in the Hivedown Agreement) as
                  owing to the Company (apart from bad and doubtful debts to the
                  extent  to which  they  have  been  provided  for in the Final
                  Completion   Statement)  will  realise  their  full  value  as
                  included in the Final Completion  Statement within the payment
                  terms agreed with the respective debtors.

       2  THE PURCHASER'S SCHEME

     2.1  The  Purchaser  will,  on or  before  Completion  Date,  nominate  the
          Purchaser's  Scheme  being a scheme which is a  contracted-out  and an
          exempt  approved  scheme for the purposes of Chapter I Part XIV of the
          Income and  Corporation  Taxes Act 1988 ("ICTA") or capable of being a
          contracted-out  and exempt  approved  scheme and which is permitted by
          its rules to receive  transfer  payments  in  respect of  Transferring
          Members on the terms of this Schedule. The Purchaser will use its best
          endeavours  to ensure that this does not change  after the  Completion
          Date.

     2.2  Unless a Grimsby Employee requests  otherwise within four weeks of the
          Completion  Date, each Grimsby  Employee who is a member of the Scheme
          immediately  before the  Completion  Date  shall join the  Purchaser's
          Scheme with effect from the Completion  Date. Any Grimsby Employee who
          has not become eligible to join the Scheme by the Completion Date will
          be able to join the  Purchaser's  Scheme  on the  date he  would  have
          become  eligible  to join the Scheme if it had  continued  to apply to
          him.

     2.3  The  Principal  Employer  and the  Purchaser  will use all  reasonable
          endeavours to ensure that each Grimsby Employee who is a member of the
          Scheme immediately before the Completion Date and who becomes a member
          of the Purchaser's  Scheme is given the opportunity (in terms approved
          by the Principal  Employer and the Purchaser,  such approval not to be
          unreasonably  withheld),  of  consenting  within  eight  weeks  of the
          Completion  Date to a transfer  of assets  being made for him from the
          Scheme to the Purchaser's Scheme.

     2.4  The  Purchaser's  Scheme will provide  benefits  and require  employee
          contributions  in respect of each  Transferring  Member's service with
          the Company from the Completion  Date which are comparable  with those
          being  provided and required  under the Scheme and on a basis which is
          substantially  no less favourable  overall (to the satisfaction of the
          Principal  Employer's  Actuary)  than the basis on which  benefits are
          being provided  immediately  before Completion for (and  contributions
          required from) the Transferring Members under the Scheme.

<PAGE>


       3  TRANSFER PAYMENT FROM SCHEME

     3.1  The Principal  Employer will use reasonable  endeavours to ensure that
          on the  Payment  Date  the  trustees  of the  Scheme  transfer  to the
          Purchaser's  Scheme  an  amount  equal to the  value  of the  benefits
          payable  under the  Scheme in  respect  of the  Transferring  Members'
          service  before the  Completion  Date  calculated as at the Completion
          Date on the bases set out in the Actuary's Letter ("TRANSFER AMOUNT"),
          with the adjustments set out below.

     3.2  The  Transfer  Amount  will be  adjusted  by  reference  to the Timing
          Adjustment for the period between the Completion Date and the close of
          business  on the day before  the date on which  payment is made to the
          Purchaser's Scheme.

     3.3  The Transfer Amount as adjusted by paragraph 3.2 will be calculated by
          the Scheme  Actuary and agreed by the  Purchaser's  Actuary  within 14
          days of the  Scheme  Actuary  notifying  the  Transfer  Amount  to the
          Purchaser's Actuary.

     3.4  Payment  to the  Purchaser's  Scheme  will be  made  on the  following
          conditions:

          3.4.1   that the Inland Revenue has given its consent to the making of
                  the payment;

          3.4.2   the Purchaser has complied  with all its  obligations  in this
                  Schedule;

          3.4.3   the Transfer Amount has either been agreed under paragraph 3.3
                  or determined under paragraph 6;

          3.4.4   the trustees of the  Purchaser's  Scheme have  confirmed  that
                  they will accept the payment on the terms set out in paragraph
                  4.

     3.5  Payment  to  the  Purchaser's  Scheme  (adjusted  in  accordance  with
          paragraph 3.2) is due on the later of the following:

          3.5.1   3 months after the Completion Date; and

          3.5.2   14 days  after  the date  when the last of the  conditions  in
                  paragraph 3.4 has been satisfied.

     3.6  The  Principal  Employer  and the  Purchaser  will use all  reasonable
          endeavours to secure agreement  between the Scheme and the Purchaser's
          Scheme  respectively  as to the  particular  assets to be  transferred
          representing  the  amount  due.  If  agreement  is not  reached by the
          Payment Date, the transfer will be in the form of assets of the Scheme
          listed on the London  Stock  Exchange  and selected by the Trustees of
          the Scheme as a representative selection of such listed assets held by
          the  Scheme.  To the extent that any part of the amount due is paid in
          cash,  the amount due will be reduced by two per cent.  Any securities
          to be transferred  will be valued at the mid-market price at the close
          of business on the relevant  stock exchange on the day before the date
          of transfer.

     3.7  If the  trustees  of  the  Scheme  do  not  pay  the  Transfer  Amount
          calculated and adjusted in accordance  with  paragraphs 3.2 and 3.6 in
          full on the  Payment  Date,  the  Principal  Employer  will pay to the
          Purchaser the amount of the difference  ("SHORTFALL") less the rate of
          corporation tax current at the date of payment.  If they make a larger
          transfer  payment to the  Purchaser's  Scheme than the Transfer Amount
          adjusted in accordance with paragraphs 3.2 and 3.6, the Purchaser will
          pay the amount of the  difference to the  Principal  Employer less the
          rate of corporation tax current at the date of payment.

<PAGE>


     3.8  No  payment  shall  be due from the Principal Employer pursuant to 3.7
          above:

          3.8.1   if the reason  for the  payment  not  having  been made to the
                  Purchaser's Scheme by the expiry of the time limit referred to
                  above is the failure of the  Purchaser's  Scheme for  whatever
                  reason to accept  the whole or any part of the  payment  or if
                  the  reason is any other  reason  outside  the  control of the
                  Trustees  of the  Scheme  but,  if no  payment is due from the
                  Principal  Employer  because of any such other reason  outside
                  the control of the Scheme, payment will become due (subject to
                  the other  provisions  of this  paragraph  3) if and when such
                  reason ceases to exist;

          3.8.2   unless the  Purchaser  undertakes  in writing to the Principal
                  Employer to pay the  Shortfall  forthwith  to the  Purchaser's
                  Scheme  and to  procure  that such  amount be  applied  by the
                  Purchaser's  Scheme to provide  benefits for the  Transferring
                  Members in respect of their pensionable  service in the Scheme
                  before the Completion Date as mentioned in paragraph 4.


       4  BENEFITS  TO BE  PROVIDED  BY THE  PURCHASER'S  SCHEME IN  RESPECT  OF
          SERVICE UNDER THE SCHEME

     4.1  The Purchaser  shall procure that the pension  entitlements  under the
          Purchaser's  Scheme in respect of any member of the Purchaser's Scheme
          who:

          4.1.1   was  a  member of the Scheme immediately before the Completion
                  Date;

          4.1.2   has not  consented  to a transfer of assets being made for him
                  from the Scheme to the Purchaser's Scheme; and

          4.1.3   who dies after the  Completion  Date, but before the last date
                  on which he is able to give such consent under the  invitation
                  referred to in paragraph 2.3.

          will be augmented.  The  augmentation  will be such that the amount of
          the widow's or widower's and any child's or dependant's  pension which
          is payable in respect of such member from the Purchaser's Scheme shall
          be increased so that the total of such benefits  payable in respect of
          such member under the Scheme and the  Purchaser's  Scheme shall be the
          same as that which  would have been  payable  had that  employee  died
          while in service immediately before the Completion Date.

     4.2  The  Purchaser  will  ensure  that  the  Purchaser's   Scheme  accepts
          liability  for  each   Transferring   Member's  accrued  rights  to  a
          guaranteed  minimum  pension and accrued rights under section 9(2B) of
          the Pension Schemes Act 1993 and provides  benefits in respect of such
          payment in accordance with  regulations  made under Sections 12C or 20
          of that Act.

     4.3  The Purchaser will ensure that the Purchaser's  Scheme  credits,  with
          effect from the Completion Date, each  Transferring  Member with final
          salary type benefit  overall at least equal in value, as determined by
          the Scheme Actuary with the agreement of the Purchaser's  Actuary,  to
          those applying for and in respect of him under the Scheme  immediately
          before the Completion  Date. For this purpose  benefits will be valued
          under both schemes on the basis of the assumptions and methods set out
          in the  Actuary's  Letter.  If the  trustees of the Scheme  notify the
          trustees of the Purchaser's Scheme that a specified part of the assets
          transferred for a particular  Transferring  Member relates to benefits
          not calculated by reference to pensionable service, the Purchaser will
          ensure that he is entitled to equivalent benefits under its scheme.

<PAGE>


       5  NO ASSISTANCE

          The  Purchaser  agrees  that  neither  it  nor  the  Company  nor  the
          Purchaser's  Scheme will take any action or provide any  assistance to
          any person  (direct or  indirect)  which might or would  result in any
          claim being made against the  Trustees of the Scheme or the  Principal
          Employer,  or in the Scheme  transferring a smaller or a larger amount
          than the amount payable under paragraph 3.1 to the Purchaser's Scheme.


       6  DISPUTES

          In the event that the Scheme Actuary and the Purchaser's Actuary shall
          not agree any matter on which their  agreement is required  under this
          Schedule,  the matter may be referred upon the  application  of either
          the  Principal  Employer or the  Purchaser to an  independent  actuary
          appointed  by the  President  for the time being of the  Institute  of
          Actuaries on the  application of either the Principal  Employer or the
          Purchaser.  That actuary shall determine the matter in accordance with
          this Schedule (including the Actuary's Letter) acting as an expert and
          not as an arbitrator and his decision shall be final and binding.  His
          expenses  shall be borne  equally by the  Principal  Employer  and the
          Purchaser  unless he makes a  recommendation  that they shall be borne
          otherwise.


       7  VOLUNTARY CONTRIBUTIONS

          Nothing previously  contained in this Schedule will apply to voluntary
          contributions or to benefits secured by them.  However,  the Principal
          Employer  will use  reasonable  endeavours  to ensure  that the assets
          representing  Transferring  Members'  voluntary  contributions will be
          transferred to the Purchaser's  Scheme,  and the Purchaser will ensure
          that in that  event  its  scheme  provides  benefits  for the  members
          concerned equal in value to the assets transferred.

       1  INTERPRETATION

          For the purposes of this Schedule 6, words and expressions  defined in
          the Share Sale  Agreement to which this  Schedule 6 is attached  shall
          have the  same  meaning  in this  Schedule  6 and,  in  addition,  the
          following terms shall have the following meanings:

          "COMMERCIALLY  REASONABLE EXPENSES" are those costs and expenses which
          a reasonable  person acting in a commercially  prudent manner,  taking
          into account (but without  imposing an absolute  requirement) the need
          to  minimise  his  expenditure,  would  expend,  in  the  case  of any
          obligation to carry out the remediation of Environmental Contamination
          pursuant  to  Environmental  Laws,  to meet that  obligation.  For the
          avoidance of doubt, Commercially Reasonable Expenses shall not include
          any costs or expenses to the extent that they are incurred as a result
          of the adoption or imposition of standards of clean-up materially more
          stringent than those which are provided for under Environmental Laws;

          22 of the  Environment Act 1995 as enacted at Completion and the first
          complete set of regulations and guidance under those provisions except
          (in the event that they are not already in issue at Completion) to the
          extent  that  any of  the  above,  when  they  come  into  force,  are
          materially more onerous than the versions of such provisions which are
          enacted or exist in draft form as at Completion;

          "ENVIRONMENT"  means air,  Controlled Waters,  land (whether on, in or
          below such land, excluding any buildings or other permanent structures
          on, in or below the land) but  including the surface of any river bed,
          the  surface  of any sea bed or any other land  covered by water,  and
          flora and fauna and all other natural resources;

          "ENVIRONMENTAL   CONTAMINATION"   means  any   discharge,   transport,
          emission,  release, leakage, spillage, escape or disposal of Hazardous
          Material  at or  from  the  Site(s)  onto  or  into  any  part  of the
          Environment;

          "ENVIRONMENTAL  LAWS" means any and all  legislation  (whether  civil,

          code of  practice,  and  guidance  note or decision  of any  competent
          regulatory  body or common law relating to pollution or  protection of
          the  Environment  which as at Completion  are in effect and capable of
          enforcement  by legal  process in the country in which the Site(s) are
          situated,  save that the EA Provisions  shall be deemed to be in force
          at Completion;

          "ENVIRONMENTAL LIABILITIES" means all claims, costs, damages, expenses
          (including reasonable professional fees incurred), losses, liabilities
          (including  without limitation  liability to third parties),  fines or
          penalties  suffered or incurred by the Company,  the  Purchaser or its
          Affiliates (or the Seller or its Affiliates in the case of the Counter
          Indemnity)  as a  direct  consequence  of or in  connection  with  any
          Environmental Proceeding;

          BUT  EXCLUDING  any  claims,   costs,   damages,   expenses,   losses,
          liabilities:

                      Laws;

                      interruption;

                  (iii)where   applicable  to  the  extent  that  they  are  not
                      Commercially Reasonable Expenses;

          "ENVIRONMENTAL PROCEEDING" means:

                  (i) subject  to (ii)  below any writ  and/or  interim or final

                           Affiliates  (or the Seller or its  Affiliates  in the
                           case  of  the  Counter   Indemnity)  are  obliged  by
                           Environmental  Laws  or  legal  process  pursuant  to
                           Environmental  Laws to  undertake  or pay the cost of

                               have known of the  circumstances  giving  rise to
                               such personal injury); or

                               or agents of the Purchaser or its Affiliates save
                               to the  extent,  in the case of damage  occurring
                               after  Completion the Purchaser  neither knew nor

                      of  Environmental  Contamination  which  would but for the
                      fact that an  environmental  authority is unaware of it be
                      more  likely  than  not  to  result  in  an  environmental
                      authority  bringing  an  Environmental   Proceeding  under
                      (i)(a) in the definition of  Environmental  Proceeding and

          "SITES(S)"   means  the   Grimsby   Properties   (including,   without
          limitation, Off Site Disposal Tips).


       2  INDEMNITY

     2.1  Subject to the provisions of this agreement,  the Seller undertakes to
          the Purchaser (for the benefit of the Company,  the Purchaser and each
          of its  Affiliates)  that it will  indemnify  and  hold  harmless  the
          Company, the Purchaser and each of its Affiliates against:

          2.1.1   all Environmental  Liabilities arising at or from the Site(s),
                  to the extent that such Environmental Liabilities are a result
                  of   Environmental   Contamination   occurring  on  or  before
                  Completion; and

          2.1.2   all  costs,  damages  expenses,  losses,  fines  or  penalties
                  suffered or incurred  by the Company or the  Purchaser  or its
                  Affiliates  as a  result  of  any  prosecutions  commenced  or
                  proceedings   taken,   or  notices   served  or  other  formal
                  enforcement  action  between  [DATE OF  SIGNATURE  OF THE 1998
                  FRAMEWORK  AGREEMENT]  1998 and  Completion  by any  competent
                  regulatory  body in connection  with the Environment or health
                  and safety as a result of any  breaches  of any  Environmental
                  Laws related to the  operation of those Sites which are owned,
                  occupied or used by the Company at [DATE OF  SIGNATURE  OF THE
                  1998  FRAMEWORK  AGREEMENT]  1998. For the avoidance of doubt,
                  damages  in  this   paragraph   2.1.2   includes  any  capital
                  expenditure reasonably required to remedy such breaches; and

     2.2  notwithstanding  paragraphs 2.1 above and 4.1 below neither the Seller
          nor any of its  Affiliates  shall be  liable  under the  Indemnity  or
          otherwise  to  the  extent  that  such  liability  arises  from  or is
          attributable  to the failure of the Purchaser to comply or procure the
          Company's  compliance  with the  provisions of paragraphs 4.2 and 5 to
          14.


       3  THE COUNTER INDEMNITY

     3.1  The Purchaser  undertakes to the Seller (for the benefit of the Seller
          and each of its  Affiliates)  that,  subject to the provisions of this
          agreement,   it  will   indemnify  and  hold  harmless  (the  "Counter
          Indemnity") the Seller and each of its Affiliates from and against all
          Environmental  Liabilities  arising  at  or  from  the  Site(s)  after
          Completion save to the extent that such Environmental Liabilities fall
          within the Indemnity.

     3.2  Notwithstanding   sub-paragraph  3.1  above,  the  Purchaser  and  its
          Affiliates  shall  not be  liable  to the  Seller  under  the  Counter
          Indemnity or otherwise to the extent that such  liability  arises from
          or is  attributable  to the  failure of the Seller to comply  with the
          provisions  of  paragraphs  3.3,  4.2, 6-8, 10, 11, 12.1, 13 and 14 of
          this Schedule.

     3.3  The Seller  shall take all  reasonable  steps to avoid or mitigate any
          Environmental  Liabilities  and  potential  Environmental  Liabilities
          which  may give  rise to a claim  under  or in  connection  with  this
          Counter Indemnity, howsoever arising.

     3.4  The provisions of paragraphs 4.2 and 12.1 shall apply equally  mutatis
          mutandis  in  respect  of the  Seller  and the  Purchaser's  rights or
          obligations in respect of the Counter Indemnity.

<PAGE>


       4  LIMITATIONS

     4.1  Neither the Seller nor any of its Affiliates shall be liable under the
          Indemnity to the extent that  Environmental  Liabilities  have arisen,
          been increased, exacerbated, enhanced or caused as a result of any act
          or omission  whether direct or indirect of the Company,  the Purchaser
          or any  Affiliates,  employees,  agents or  contractors  thereof after
          Completion  (including,  without limitation,  any change of use of the
          Site(s) which for the avoidance of doubt shall include  closure of all
          or any part of the Sites but shall not include any material  change of
          process  within the existing  plant  and/or  buildings or any material
          change to or development of the business and operations  carried on at
          any Site  which  does not  result  in any Site or any part of any Site
          ceasing  to be used  for  general  industrial/manufacturing  of a type
          materially  similar  to the  existing  Site  operation  and  the  word
          "omission" as used in this paragraph 4.1 shall not mean any failure by
          the Company or  Purchaser  to carry out  remediation  or  preventative
          action in circumstances where it is not within their power to do so or
          where the  Purchaser  is not aware or could not  reasonably  have been
          aware of the  Environmental  Liabilities in question or where (without
          prejudice to the  obligations of the Purchaser  under paragraph 5) the
          rights of the Purchaser to bring a claim under the Indemnity  would be
          prejudiced as a result thereof.

     4.2  No  claim  may  be  made  by  the  Purchaser  for  any   Environmental
          Liabilities under this Indemnity against the Seller to the extent that
          any Environmental Liabilities arise:

          4.2.1   as a result directly or indirectly of information  voluntarily
                  given  by  the   Purchaser  or  the  Company  (but  only  post
                  Completion  in  the  case  of  the  Company)  to a  regulatory
                  authority  in  circumstances  other  than  where  there  is  a
                  mandatory  reporting  requirement under  Environmental Laws or
                  where  information  is given as  required  in the  context  of
                  applications for or variations to authorisations, licences and
                  other forms of environmental  consent required by the business
                  in the  course  of the  Company's  or the  Purchaser's  normal
                  business   activities  or  where  the  Seller  has  previously
                  proposed or approved this course of action in writing; and

          4.2.2   from any  admission of liability  by a  representative  of the
                  Purchaser  holding a rank not less  than  that of Senior  Vice
                  President in respect of any  clean-up  which needs to be done,
                  except where the Seller has approved such admission in writing
                  such approval not to be unreasonably withheld or delayed.

     4.3  No claim against the Seller or its  Affiliates  under the terms of the
          Indemnity  for any  Environmental  Liabilities  shall be valid  unless
          notice has been served on the Seller in accordance with the provisions
          of paragraph 7 within 10 years of Completion.

     4.4  The  Seller's  liability  under  the  Indemnity  shall be  limited  in
          accordance  with the  provisions  of Clause 5,  except for  sub-Clause
          5.14.2 (save for the proviso to sub-Clause  5.14) and sub-Clause 5.15,
          the subject matter of which will be governed by the provisions of this
          Schedule.

     4.5  In the event that the  Indemnitor (as defined in paragraph 6.1) either
          incurs external charges, costs and expenses for environmental services
          or internal charges for its own environmental services, in either case
          including but not limited to testing and/or analytical services and/or
          contaminated  soil  disposal  facilities,  in  connection  with  or in
          relation to any actual or potential  Environmental  Liabilities  under
          the Indemnity or Counter Indemnity (as appropriate) then such external
          charges,  costs and expenses shall be deemed to be payments made under
          the  Indemnity or Counter  Indemnity  (as  appropriate).  Any internal
          charges shall be made on the same basis as the  Indemnitor  charges to
          its own business or its Affiliates.

     4.6  It is hereby expressly agreed that, save where the Seller has accepted
          liability  or  becomes   otherwise  liable  under  the  terms  of  the
          Indemnity,  all  costs  incurred  by the  Purchaser  in  carrying  out
          environmental  analyses  and tests of the Site(s)  (and its (or their)
          surrounds) shall be borne by the Purchaser.

<PAGE>


     4.7  The   Seller   shall  be   liable   under   the   Indemnity   for  any
          asbestos-related  personal  injury  unless and to the extent  that any
          works  carried out by the  Purchaser or its  Affiliates or the Company
          after  Completion,  were not carried out by a reputable  contractor or
          contractors,  who were duly and  properly  authorised  or  approved to
          undertake  such  works  to at  least  the  standards  of the  relevant
          federal,  state or other  regulatory  authorities  published  by or in
          operation (in  accordance  with good  industry  practice) at all times
          during the carrying out of such works.


       5  MITIGATION

          The  Purchaser  shall take all  reasonable  steps after  Completion to
          avoid or  mitigate  any  Environmental  Liabilities  and/or  potential
          Environmental  Liabilities to the extent it is within the  Purchaser's
          power to do so, which may give rise to a claim under or in  connection
          with this  Indemnity  howsoever  arising.  Such steps will include but
          shall not be limited to:

     5.1  carrying out (where  reasonably  practicable)  appropriate  soil tests
          before  taking  any  action  which  is  likely  to  cause  a  material
          disturbance to soil;

     5.2  where reasonably practicable carrying on its activities on the Site(s)
          so as to minimise  disturbance  to known areas of existing or probable
          soil contamination (other than deliberate removal of such contaminated
          soil)  without  incurring  abnormal  unusual or  excessive  cost in so
          doing;

     5.3  the Purchaser  (with the approval of the Seller not to be unreasonably
          withheld  or  delayed)  settling  a claim of any party  (not  being an
          Affiliate of the Purchaser) which will or may fall within the terms of
          the Indemnity,  the costs and expenses associated with such settlement
          (so  approved  by  the  Seller)  being  deemed  to  be   Environmental
          Liabilities for the purposes of this  agreement)  provided always that
          nothing in this paragraph 5.3 shall oblige the Purchaser to enter into
          any settlement which it does not, in its sole discretion,  consider to
          be in the best interests of its operations;

     5.4  making  reasonable  and timely  efforts to pursue  claims  against any
          third parties (including  insurers) who may have some liability to the
          Purchaser  in respect of the matter in question  provided  always that
          this  shall  not  limit  or  restrict  or  operate  in  any  way  as a
          pre-condition  to the rights of the  Purchaser  to make a claim  under
          this Indemnity; and

     5.5  using  reasonable  endeavours to avoid acts or omissions of the nature
          described in paragraph 4.1.


       6  NOTIFICATION

     6.1  As soon as reasonably  practicable after either party becomes aware of
          any actual or potential Environmental  Liabilities which may give rise
          to a claim  by it  under  the  Indemnity  or  Counter  Indemnity  (the
          "Claimant") (whether or not the Claimant is of the opinion that it has
          a valid claim  against the other party under the  Indemnity or Counter
          Indemnity (the  "Indemnitor"))  the Claimant shall give written notice
          thereof to the  Indemnitor  (and  thereafter  will keep the Indemnitor
          fully informed of all material  developments  relating thereto).  Such
          written  notice shall  include all  material  details of any actual or
          potential   Environmental   Liabilities   (including   the  Claimant's
          reasonable   estimate   of  the  extent  of  and,   where   reasonably
          practicable, the cost of remediation of the Environmental Liabilities,
          as a result thereof).

     6.2  Neither party shall admit,  settle or discharge any claim or liability
          which might  constitute a claim  against the other under the Indemnity
          or Counter  Indemnity (as  appropriate)  without having first served a
          notice  under  this  paragraph  6 and  given  the  other a  reasonable
          opportunity  to  consider  the  circumstances  referred to in the said
          notice.

<PAGE>


       7  CLAIMS

          In the event  that the  Claimant  wishes to make a claim  against  the
          Indemnitor  under the Indemnity or Counter  Indemnity (as appropriate)
          then it shall do so by  giving  notice in  writing  of the same to the
          Indemnitor  giving such details as are then in its  possession  of the
          relevant subject matter of such claim.


       8  CONDUCT

          If any notice is received by either party under  paragraphs 6 or 7 the
          Claimant shall if so requested by the Indemnitor  take all steps which
          are necessary and reasonable to avoid, resist,  appeal,  compromise or
          defend any claim and any adjudication in respect thereof,  (subject to
          the Claimant being indemnified against all cost and expenses which may
          reasonably and  necessarily  be incurred in connection  therewith) and
          the Indemnitor shall (subject to the provisions of this paragraph), at
          its request,  be allowed to conduct any  negotiations,  proceedings or
          appeals  incidental  thereto PROVIDED ALWAYS that if the claim relates
          to or arises from a Site which at the time is owned,  occupied or used
          by the  Company  and which is  operational  at the date of the  notice
          under  paragraph  7 then  the  Purchaser  shall  have  conduct  of all
          negotiations,  proceedings  or appeals  incidental  thereto  but shall
          nonetheless   keep  the  Seller   fully   informed  of  all   material
          developments relating to the subject matter of the claims.


       9  SITE ACCESS

          If any notice is received by the Seller under paragraphs 6 or 7:

     9.1  the Seller  and/or its  agents and  contractors  shall be free to have
          access to any  Site(s)  to the  extent  it is within  the power of the
          Company,  the  Purchaser or its  Affiliates,  during  normal  business
          hours, and after reasonable prior notice, and, if so required,  in the
          presence of an  authorised  representative  of the Purchaser to assess
          (including but not limited to assessment by soil sampling and testing)
          the  extent  of  the   Environmental   Liabilities   and/or  potential
          Environmental  Liabilities  and to  determine  the action  required in
          order to remediate  such  liabilities;  (such actions to be subject to
          the prior agreement of the Purchaser (including as to the action to be
          taken) such agreement not to be unreasonably withheld) and

     9.2  the Purchaser shall (during normal business hours) allow the Seller or
          its agents access to inspect and take copies of such books and records
          of the business of the Company  and/or the  Purchaser  relating to the
          Site(s)  as may be  necessary  in  connection  with any  Environmental
          Liabilities and/or potential Environmental Liabilities.


      10  DISCUSSIONS

          Upon either  party  having  given a notice  under  paragraphs  6 or 7,
          either the Seller or the  Purchaser  may  request a meeting as soon as
          practicable  to discuss  the matter  (and if either  does so the other
          party shall comply  promptly with such request) and,  irrespective  of
          whether there has been any agreement on liability, each party shall be
          fully involved in any discussions  and/or  negotiations with any party
          imposing or seeking to impose any Environmental Liabilities.


      11  DISPUTE RESOLUTION

          Upon either party giving a notice in accordance  with  paragraph 7, in
          the  event  that the  Seller  and the  Purchaser  are  unable to agree
          promptly any factual  matter  relevant to a claim under this Indemnity
          or Counter  Indemnity  (as  appropriate)  or in the event of any other
          matter being referred to the Experts in accordance  with this Schedule
          6 then the following provisions of this paragraph 11 shall apply:

<PAGE>

          as  experts  and  not  arbitrators)  in  relation  to the  Environment
          relevant to the claim or  potential  claim  (having at least ten years
          relevant  experience)  shall be appointed  by mutual  agreement of the
          parties  hereto  (and the  parties  shall each be obliged to use their
          respective  best endeavours to reach agreement as soon as practicable)

          shall   instruct  the  Experts  to  issue,   as  soon  as   reasonably
          practicable, a formal written opinion pertaining to the matter of fact
          referred to them.  In any event the  Experts  shall be  instructed  to

          considered  to undertake any clean-up work in respect of the claim for
          which  they have so acted on or around  the  Site(s),  save  where the
          parties  hereto  mutually  agree  to  waive  this  provision.  For the
          avoidance  of doubt,  either  party may  withhold  such consent in any
          event.


      12  ACCEPTANCE OF LIABILITY

          In the event that the Seller  admits that it has any  liability to the
          Purchaser  under the  Indemnity  (or where the Seller agrees to accept
          the Purchaser's claim as falling within the Indemnity  notwithstanding
          the fact that no  Environmental  Liability  may at that  point in time
          have arisen):

    12.1  the Seller shall have the right  independently  to determine  whatever
          measures are appropriate in order to remediate  pursuant to applicable
          Environmental Laws the subject matter of the claim under the Indemnity
          and furthermore the Seller shall have the right independently to carry
          out such remediation itself (or through suitable third party agents or
          contractors)  provided that in so doing the Seller (or its said agents
          or contractors) shall be obliged to use reasonable endeavours to avoid
          causing  undue  interruption  to the  conduct of the  business  of the
          Company and/or the Purchaser;

    12.2  the Seller and/or its agents and contractors shall, in addition to the
          rights of access  provided for in  paragraph 9 above,  be free to have
          access to the Site(s) if currently owned,  leased or, where within the
          power of the Company and its Affiliates  during normal  business hours
          after reasonable prior notice, and if so required,  in the presence of
          an  authorised  representative  of the  Purchaser,  to  carry  out the
          remediation referred to in paragraph 12.1 above.

      13  STATEMENTS

          In the event of any circumstances arising which do or may give rise to
          Environmental  Liabilities  which  may fall  within  the  terms of the
          Indemnity  or the  Counter  Indemnity  (as  appropriate)  neither  the
          Company,  Purchaser  nor  the  Seller  (nor  any of  their  respective
          Affiliates)  shall  make any  public  statements  (including,  for the
          avoidance of doubt, any statement to any regulatory authority,  unless
          required  by  law or in an  emergency)  regarding  such  circumstances
          without  first  discussing  with the other party and reaching  written
          agreement (such agreement not to be unreasonably  withheld or delayed)
          on the text of any such public statement before it is made.


      14  GENERAL

    14.1  Any  information,  records,  or other  material  of one party shall be
          treated as strictly  confidential by the other party except when it is
          required  to be used in order to comply  with an order of the court or
          regulatory  authority  or it is used by the other party to enforce its
          rights under this Schedule 6 or so as to make an insurance claim.

    14.2  The Purchaser's and its Affiliates'  exclusive  remedies in respect of
          any claims  which fall within the scope of the  Indemnity  shall be in
          accordance  with the  provisions of this Schedule 6, and the Purchaser
          on  behalf  of  itself  and its  Affiliates  hereby  waives  all other
          remedies whether in contract,  tort  (including,  for the avoidance of
          doubt,  negligence),  or howsoever otherwise arising which it may have
          against  the  Seller or any of its  Affiliates  at law or in equity in
          respect of the matters  which fall  within the scope of the  Indemnity
          and, for the  avoidance of doubt,  if such a claim under this Schedule
          could also give rise to a Claim or a claim  under any other  provision
          of this agreement in respect of the same subject matter, the Purchaser
          may only bring a claim under this Schedule 6.

    14.3  The Seller  undertakes to co-operate with the Purchaser and assist the
          Purchaser in achieving a transfer to the  Purchaser (or as it directs)
          of all Environmental Authorisations,  permits and licences held by the
          Seller at Completion.


      15  CO-OPERATION

          The Purchaser undertakes that wherever co-operation is required by the
          Company  to  ensure   compliance  with  the  Purchaser's   obligations
          hereunder,  the Purchaser will use its reasonable endeavours to ensure
          that the Company provides the requisite co-operation.

defined herein and specified in the attached Schedules, collectively referred to
herein as the "parties" or singularly as "party" and each party hereto variously
referred to as the "supplying  party" or the  "receiving  party" as the case may
be.

shares of stock of Newco; and,

      Whereas, the primary asset of Newco is the titanium dioxide
manufacturing plant located at Grimsby, U.K. (the "Grimsby Plant"); and

      Whereas,  concurrent  with the execution of this  Agreement,  Purchaser is
acquiring the Tioxide North American titanium dioxide business; and

      Whereas,  concurrent with the execution of this Agreement,  TEL has agreed
to sell the whole of the issued share capital in Newco,  to Purchaser to provide
Purchaser and its Affiliates with manufacturing  capacity to support Purchaser's
North American business; and

      Whereas,  the Products  currently sold in North America  include  specific
products  not  currently  manufactured  by Newco and the parties  wish to ensure
continued  availability  of the Products while Newco and its  Affiliates  expand
their  product  range to ensure  continuity  and while  the  customers  for such
Products carry out the necessary trials to approve Products newly  manufactured;
and

      Whereas,  the Products  currently sold by the Grimsby Plant are desired by
TEL (and its Affiliates) for sale in Europe for a limited period of time; and

wish, for a limited period of time, to exchange as between one another equal, or
close to equal  quantities  of the Products  specified  below for no  additional
consideration other than the Products  themselves,  or as otherwise specified on
the terms and subject to the conditions contained herein; and

products  exchanged  and the  duration of the  exchange so as  independently  to
supply the needs of each  company's  own  customers  at or before the end of the
Contract Period; and

updated forecast.

            3.6 Each forecast  provided  according to Subclauses 3.2 - 3.4 shall
be  non-binding  and for  planning  purposes  only  and  does  not  represent  a
commitment by the supplying  party to deliver and the receiving  party to accept
delivery of any quantity of Product, except that for each such forecast:

                  3.6.1  Month  1  requirements  shall  be a fixed  and  binding
                  commitment  by the  receiving  party  to  accept  delivery  of
                  Product quantities by grade, Quality and package type.

                  3.6.2  Months  2 and 3 shall be  variable  by plus or minus 5%

                  party and the receiving party.

            3.7 The  parties  will adjust  forecasts  for Months 4 through 12 in
each rolling  forecast in a good faith attempt both to meet the  requirements of
Subclause 3.1 and to ensure that the total  quantity of Tioxide  Products and of
Newco Products are equal at the end of each full year of the Contract Period.

            3.8 Each forecast shall also report the total quantities of Calciner
Discharge Product and of Finished Product supplied and received during each full
year following the Completion Date, so as to enable the parties to calculate any
Product Imbalances.

supplying party will make good faith efforts to avoid package damage  associated
with loading products of dissimilar  package size. The supplying party will have
no liability for package damage in the case of containers with more than one (1)

                  party  for its use at the  relevant  Delivery  Point  at least
                  sixty (60) days in advance of any delivery  date in sufficient
                  quantity  to allow  supplying  party to meets its  commitments
                  hereunder.

                  4.4.2 All  Packaging  Materials  will  display  the  receiving
                  party's  name,  trademark(s),   if  any,  and  other  relevant
                  information  for use by the supplying  party in fulfilling the
                  receiving party's requests for Product.

                  4.4.3  Any   failure  to  supply   Product   due  to  lack  of
                  availability  of proper  Packaging  Materials will be deemed a
                  failure  of  receiving   party  to  perform  its   obligations
                  according to the  provisions of this Agreement and will not be
                  a failure of the  supplying  party to perform its  obligations
                  according  to the  provisions  of this  Agreement,  unless the
                  supplying  party is solely  negligent for lack of availability
                  of proper Packaging Materials.

                  4.4.4 During the first one hundred eighty (180) days following
                  the Completion Date or until  sufficient  Packaging  Materials
                  are provided by the  receiving  party,  whichever  shall first
                  occur,  the  supplying  party shall  utilize its own Packaging
                  Materials,  with  associated  costs  to be  reimbursed  by the
                  receiving  party.  Receiving  party shall be  responsible  for
                  re-labeling in accordance with Subclause 4.4.2.

<PAGE>

            4.5  All  Product  made  available  by  the  supplying   party,   in
satisfaction of an order from receiving party,  will be promptly  transported by
receiving party from the Delivery Point.

            4.6 Product will be made available  throughout the delivery month in
accordance with the supplying party's monthly production schedule.

            4.7 The parties will use  reasonable  efforts to cooperate  with one
another in providing any necessary  documentation to support these  transactions
and any subsequent shipments or exports contemplated hereunder.

            4.8 The parties acknowledge that:

            (a)   This  Agreement is of short  duration  and designed  solely to
                  facilitate  the  intent  of  the  parties   described  in  the
                  Recitations,

            (b)   There are no  significant  or material  differences  among the
                  financial values of the Products listed in Schedules A and B,

            (c)   There are no  significant  or material  differences  among the
                  financial  values of the Products  listed in Schedules "C" and
                  "D", and

            (d)   Circumstances  relating  to  documentation,  customs,  duties,
                  taxation,  or other legal  requirements  may  necessitate  the
                  assignment  of a financial  value to a particular  quantity of
                  Product.

            The parties  therefore agree that where required as in Subclause 4.8
(d), the Calciner  Discharge Product value and the Finished Product value at the
time of  delivery  to the  Delivery  Point  shall be  deemed  to be equal to the
Calciner Discharge Product Value and the Finished Product Value, respectively of
such Product, and shall not be applied differently to either Tioxide Products or
Newco Products.

      5.    Product Imbalances.

            5.1 If a Product  Imbalance  should occur, the parties will promptly
cure such Product Imbalance under the following terms:

                  5.1.1 The "Newco Imbalance  Value" for such Product  Imbalance
                  shall be the sum of:

                        (1) The Calciner Discharge Product Value of the Newco
                        CD Product Imbalance, if any; and

                        (2) The Finished Product Value of the Newco FP
                        Imbalance, if any.

<PAGE>

                  5.1.2 The "Tioxide Imbalance Value" for such Product Imbalance
                  shall be the sum of:

                        (1) The Calciner Discharge Product Value of the
                        Tioxide CD  Product Imbalance, if any; and

                        (2)  The  Finished  Product  Value  of  the  Tioxide  FP
                        Imbalance, if any.

                  5.1.3 Newco,  if the Newco  Imbalance Value is larger than the
                  Tioxide  Imbalance  Value,  or TEL, if the  Tioxide  Imbalance
                  Value  is  larger   than  the  Newco   Imbalance   Value  (the
                  "Reimbursing  Party")  shall be  responsible  to reimburse the
                  other party (the "Reimbursed Party") in an amount equal to the
                  net of the larger of the Newco Imbalance Value and the Tioxide
                  Imbalance  Value less the smaller of the Newco Imbalance Value
                  and the Tioxide Imbalance Value (the "Net Imbalance Value").

                   5.1.4 The  Reimbursing  Party will  reimburse the  Reimbursed
                  Party by (a)  supplying a quantity of  Finished  Product,  (b)
                  supplying a quantity of Calciner Discharge Product, and/or (c)
                  making a cash  payment,  such that the sum of (1) the Value of
                  such  Finished  Product,   (2)  the  Value  of  Such  Calciner
                  Discharge  Product,  and (3) the  amount  of the cash  payment
                  shall be equal to the Net Imbalance Value.

                  5.1.5 For any  Product to be supplied  pursuant  to  Subclause
                  5.1.4,  (a) the  Reimbursing  Party  shall  specify  the total
                  quantity and (b) the  Reimbursed  Party shall specify  whether
                  the  Product  will be Calciner  Discharge  Product or Finished
                  Product. The cash payment will be adjusted accordingly.

                  5.1.6 The  calculations,  determinations,  and decisions to be
                  made in  Subclauses  5.1.1.  through  5.1.5 will be  completed
                  within  thirty  (30)  days of the  occurrence  of the  Product
                  Imbalance and any cash payment will be made by the Reimbursing
                  Party within fifteen (15) days thereafter.

                  5.1.7 For any  Product to be supplied  pursuant to  Subclauses
                  5.1.4 and  5.1.5,  the  Reimbursed  Party  shall  specify  the
                  Product  grade(s),  Quality and package type,  and the parties
                  will mutually agree upon delivery timing.

                  5.1.8  For any  cash  payment,  VAT  shall be  charged  to the
                  Reimbursed Party as appropriate.

            5.2 Any quantities of Product supplied and cash payments made by the
Reimbursing  Party  pursuant to Subclause  5.1.4  through 5.1.6 will be excluded
from consideration in the determination of any later Product Imbalance.

<PAGE>

            5.3 The provisions of this Agreement  relating to Product Imbalances
shall not apply where any Product  Imbalance  has been caused by a Force Majeure
event or circumstance, except to the extent that :

                  (a) at or near the end of the Contract  Period the  corrective
                  measures of Subclauses  13.2 or 13.3 are  sufficient to remove
                  what would  otherwise be a  contribution  of the Force Majeure
                  event to a Product Imbalance, or

                  (b) the party  not  declaring  a Force  Majeure  elects  under
                  Clause  13.3(b) to continue to receive  Product  during  Force
                  Majeure.

            5.4 The parties'  obligation to cure Product Imbalances  pursuant to
Clauses 5.1 and 5.2 shall survive termination of this Agreement.

      6.    Quality, Adjustments:

            There  will  be no  change  in the  specifications  of  the  Product
produced by the  supplying  party  without the  express  written  consent of the
receiving  party.  The supplying party shall give sufficient prior notice to the
receiving  party of any  significant  change(s) in raw materials,  manufacturing
processes,  or test methods for mutual  assessment of the probable effect on the
receiving  party's  Product  performance.  Final Product  attributes will remain
unchanged and will be consistent with the Specifications.

      7.    Term and Termination.

            This Agreement  shall become  effective on the  Completion  Date and
terminate at the end of the Contract Period.

                  7.1  Clauses  5, 8, 9, 10,  11,  12,  15 and 19 shall  survive
                  termination of this Agreement.

                  7.2 If both  TEL and  Newco  reach  agreement  at the  time of
                  submission of any rolling  twelve-month  forecasts  that their
                  respective  needs for  Products  for all future  months  after
                  Month 2 of the  forecast  will be zero,  then in that case the
                  Contract Period will be deemed to end at the end of such Month
                  2 for the purposes of this Agreement.

      8.    Warranty:

            Each supplying  party warrants to each receiving party only that any
Product when supplied will meet the Specifications  for the Product.  EXCEPT FOR
THE FOREGOING AND AS EXPRESSLY PROVIDED HEREIN, SUPPLYING PARTY MAKES NO EXPRESS
OR  IMPLIED  WARRANTY   (INCLUDING,   WITHOUT  LIMITATION,   THE  WARRANTIES  OF
MERCHANTABILITY,  FITNESS FOR A PARTICULAR PURPOSE OR FROM ANY COURSE OF DEALING
OR TRADE USAGE)  REGARDING  THE PRODUCT.  Receiving  party  assumes all risk and
liability  for  results  obtained  by the use of the  supplying  party  Product,
whether used alone or in combination with other materials.

<PAGE>

      9.    Claims:

            9.1 With respect to either Tioxide  Products or Newco  Products,  no
claim shall be greater in amount than the Value of the  Product  (plus  freight,
duty and disposal  costs)  exchanged  hereunder in respect of which  damages are
claimed except in the case of willful breach of this Agreement.  Failure to give
notice of a claim within one hundred eighty (180) days from date of delivery, or
the date fixed for delivery (in case of non-delivery), shall constitute a waiver
by the  receiving  party of all claims in respect of the Product so delivered or
not  delivered,  as the case may be except in the case of willful breach of this
Agreement. No Product shall be returned to the supplying party without supplying
party's  permission,  which shall not be unreasonably  withheld or delayed,  and
then only in the  commercially  reasonable  manner  prescribed  by the supplying
party.  No claim  shall be allowed  for Product  that has been  processed  (e.g.
"finished") in any manner.  Claims include,  without  limitation,  claims of any
kind, whether or not (a) for loss,  damage,  expense or injury, (b) with respect
to the Product  delivered or for  non-delivery of the Product,  or (c ) based on
supplying  party's  breach  of  warranty,   contract,   statute,  regulation  or
negligence, strict liability or any tort.

            9.2 No Claim for failure to deliver on time or at all, will be valid
if the reason for said late delivery or  non-delivery  is the failure  either in
whole or in part, by the receiving  party to provide the supplying  party with a
sufficient  quantity of  Packaging  Materials  for the  Products  ordered by the
receiving party.

      10.   Remedy:

            Except in the case of willful  breach of this  Agreement,  a party's
exclusive  and sole remedy for any claim  shall be the  recovery of the Value of
the Product  exchanged  with the other party (plus  freight,  duty and  disposal
costs) in the transaction  giving rise to the claim. Such recovery may be in the
form of cash or in the form of Product at the  discretion  of the party  against
whom the claim is made.

      11.   Patent Warranty:

            The  supplying  party  warrants that the use or sale of the Products
delivered  hereunder  will not infringe the claims of any validly  issued patent
covering the Products themselves,  but does not warrant against infringement due
to: (a) the use of the  Products in  combination  with other  Products (or third
party products of other  manufacturers)  or materials or in the operation of any
process,  or (b) the  compliance  by  supplying  party  with any  specifications
provided to supplying party by the receiving party.

      12.   No Consequential Damages:

            Neither  party shall be liable for  special,  indirect,  incidental,
punitive or consequential  damages (including,  without limitation,  damages for
loss of business profits,  business  interruption or any other loss), whether or
not caused by, or  resulting  from,  the  negligence  of such party even if such
party has been advised of the possibility of such damages.

      13.   Force Majeure:

            13.1 Force Majeure is an event or circumstance beyond the reasonable
control of the party  claiming the Force  Majeure  including but not limited to:
act of God,  fire,  flood,  explosion,  hurricane,  breakdown  of  machinery  or
equipment, governmental action or inaction or request of governmental authority,
accident,  strike,  lockout, labor trouble or shortage,  inability to obtain raw
material,  power, equipment or transportation,  but the party claiming the Force
Majeure shall be diligent in attempting to remove such cause or causes and shall
promptly  notify  the  other  party of its  extent  and  probable  duration.  No
liability  shall  result to  either  party  from  delay in  performance  or from
non-performance  caused by a Force  Majeure  other than that  described  in this
Clause 13 and in Clause 14 and this Agreement shall remain otherwise unaffected.

<PAGE>

            13.2 If the party declaring a Force Majeure is the supplying  party,
the receiving party shall be entitled to reduce its own quantity commitments (by
grade,  Quality,  and package of such receiving  party's  choice) as a supplying
party in an amount equal to the quantity by which the non-performing party fails
to  perform.  The  non-performing  party  shall have no  obligation  to purchase
quantities  of  Product  from other  sources to enable it to perform  under this
Agreement.

            13.3 If the party declaring a Force Majeure is the receiving  party,
the supplying party will be entitled:

                  (a) to reduce its own  commitments as a receiving  party in an
                  amount equal to the quantity by which the non-performing party
                  fails to perform, or

                  (b) to continue  to receive  Product  from the  non-performing
                  party.

            13.4 In  order  to  claim  a  Force  Majeure  hereunder,  the  party
attempting to excuse its delay in performance or non-performance must notify the
other party  within 24 hours of  obtaining  knowledge  of the Force  Majeure and
confirm the Force Majeure event in writing within 5 Business Days thereafter. If
the  other  party  does not  agree  that the  event or  circumstance  is a Force
Majeure,  that  party  may  dispute  the  claim  under  the  Dispute  Resolution
provisions contained herein.

            13.5 YEAR 2000  ISSUE.  A delay in  performance  or  non-performance
attributable to improper processing, management, manipulation, miscalculation or
misreading of data by  computer-operated  systems  arising out of processing for
the year 2000 shall not constitute a Force Majeure.

            14.   Allocation:

            14.1 If a Force Majeure event or  circumstance  occurs which results
in the failure of the supplying party to supply Product to the receiving  party,
supplying  party  will  distribute  its  available  supply  pro rata  (based  on
deliveries  in the three  calendar  months prior to the Force  majeure  event or
circumstance)  between  the  receiving  party  and the  aggregate  of all  other
purchasers,  including,  third  parties as well as  divisions,  joint  ventures,
business units, affiliates and subsidiaries of supplying party, for the duration
of such Force Majeure event or circumstance without liability for any failure of
performance  that  may  result  therefrom.   For  the  avoidance  of  confusion,
distribution  among  such  other  purchasers  will be made on such  basis as the
supplying party may deem fair and practical after first  determining the portion
to be provided to receiving party.

<PAGE>

            14.2 If a  non-Force  Majeure  event or  circumstance  occurs  which
results in the failure of the supplying party to supply Product to the receiving
party according to the forecast commitments hereunder, the supplying party shall
meet all of its supply  obligations under this Product Exchange  Agreement prior
to,  and in  preference  over,  any  other  supply  obligations  to  purchasers,
divisions,  joint  ventures,  business  units,  affiliates and  subsidiaries  of
supplying party.

      15.   Government Action:

            If any Government action should place or continue limitations on the
terms of this  Agreement  such that it would be  illegal  or  against  public or
Government  policy for  supplying  party to receive full value (i.e.  equivalent
exchanged  product) for its Product,  supplying party shall have the option: (a)
to continue to perform under this  Agreement  subject to such  adjustments  that
supplying party may deem necessary to comply with such Government action; (b) to
revise this Agreement,  subject to receiving party's written approval,  in order
to most nearly  accomplish  the  original  intent of this  Agreement;  or (c) to
terminate  performance  of the  affected  portions  of  this  Agreement  without
liability for damages.

      16.   User Protection and Product Information:

            The receiving  party  warrants that it will use its own  independent
skill and  expertise in  connection  with the selection and use of the supplying
party's  Product and that it possesses the skill and expertise to safely handle,
store,  transport,  use, and dispose of the Product.  In  connection  therewith,
receiving party agrees to:

            16.1 Familiarize itself with available safety and health information
and precautions, including, but not limited to, those contained in any pertinent
material safety data sheet;

            16.2 Adopt and follow safe handling, storage,  transportation,  use,
and disposal practices with respect to the Product,  including,  but not limited
to, those required by applicable law and regulation; and

            16.3 Instruct its  employees,  independent  contractors,  agents and
customers in the warning and safe use practices  required in connection with the
unloading, handling, storage, transportation, use and disposal of the Product.

      17. Labeling and Literature, Name on Product:

            Each party hereto acknowledges that there may be risks and liability
resulting from the use of each party's Products.  Each party hereto acknowledges
that it has  received  and is  familiar  with the  supplying  party's  labeling,
literature  and any  pertinent  Material  Safety  Data  Sheets  ("MSDS"  sheets)
concerning such Products and their properties.  The receiving party will forward
such  information  to  receiving  party's  employees  and any others  (including
receiving party's customers),  who may handle, process or sell such Product from
supplying  party and advise such  parties to  familiarize  themselves  with such
information.

<PAGE>

      18.   Taxes, VAT, Import Duties

            18.1 The receiving  party is  responsible  for payment of all taxes,
duties and VAT due and payable upon movement of Product under this Agreement.

            18.2  Where VAT is payable  by one party to  another,  this shall be
charged  by means of a valid VAT  invoice  issued  pursuant  to the  legislation
extant in the country where the VAT charge is levied.

            18.3 For any goods which have been supplied to the  receiving  party
VAT-free  on the basis that those  goods are to be  exported  from the  European
Union by the receiving  party, the receiving party is required to provide within
one month of the date of supply of product a certificate of shipment proving the
goods were removed from the European Union. If such  certificate is not provided
within that time period,  then the  supplying  party shall charge and  receiving
party shall pay VAT and  associated  penalties,  if any. Such VAT and associated
penalties shall be invoiced by the supplying  party and paid,  within 15 days of
receipt of the invoice, by the receiving party.

      19.   Confidential Information:

            19.1 For purposes of this Clause:

      19.1.1  "Confidential  Information" means all information  received by the
receiving party from the disclosing party relating to the disclosing  party, its
Affiliates  and  the  businesses  conducted  by the  disclosing  party  (whether
pursuant to this Agreement or otherwise)  including not only written information
but information transferred orally,  visually,  electronically,  or by any other
means. For the avoidance of doubt, the term  Confidential  Information shall not
include:

            (i)   information that is in the public domain at the date of
                  this Agreement;

            (ii)  information  that  subsequently  comes into the public domain,
                  otherwise than as a result of a breach of this Agreement,  but
                  only after it has come into the public domain;

            (iii) information  which the receiving party or its  Representatives
                  obtain  from a  third  party  not  under  any  confidentiality
                  obligation   to   the   disclosing   party   respecting   such
                  information;

            (iv)  information  which the receiving party or its  Representatives
                  at the time of disclosure  already has in its  possession  and
                  which is not  subject  to any  obligation  of secrecy on their
                  part to the other party;

            (v)   information  which is independently  developed by employees of
                  the receiving party or its  Representatives  who had no access
                  to the information disclosed by the disclosing party.

      19.1.2 "Representatives" means Affiliates, directors, officers, employees,
agents  or  representatives  of  either  party  or  its  Affiliates,  and  their
respective solicitors, accountants, consultants and financial advisors.

<PAGE>

      19.2 Each party hereto  undertakes  to maintain  Confidential  Information
received  by it, its  Affiliates  or its  Representatives  relating to the other
party or the other  party's  Affiliates  in  confidence  and not  disclose  that
Confidential  Information  to any person other than its  Representatives  except
with the prior written approval of the other party.

      19.3 Each  party  undertakes  only to  disclose  to  Representatives  such
Confidential  Information  relating  to the  other  party or the  other  party's
Affiliates  as is  reasonably  required  for  the  purposes  of  performing  the
obligations  under  this  Agreement  and  only  to  Representatives  whom it has
informed of the  confidential  nature of the  Confidential  Information  and who
undertake to keep it confidential.  Such  information  shall not be used for any
other purpose than the performance of the parties' obligations  hereunder.  Each
party shall be responsible for breach of such confidentiality  undertaking by it
or its Representatives.

      19.4 In the event that, after receipt of Confidential Information,  either
party, or any person or Representative  to whom it has transmitted  Confidential
Information,  becomes  legally  required  (by oral  questions,  interrogatories,
requests for information or documents,  subpoena,  civil investigative demand or
similar  process or otherwise) to disclose any of the  Confidential  Information
received,  the legally compelled party shall provide the other party with prompt
written notice of that requirement so that the other party may seek a protective
order or other  appropriate  remedy but shall not be obliged to delay disclosure
if to do so would be in breach of any conditions for such disclosure  imposed by
the authority compelling  disclosure and in any event should the other party not
be  successful in seeking or obtaining a protective  order or other  appropriate
remedy,  the other party  shall waive  compliance  with the  provisions  of this
Agreement for such particular case to enable the legally  compelled party or its
Representative to comply with any such legal requirement.

      19.5 Disclosure of Confidential Information to permitted assigns shall not
be a  violation  of this  Clause  19,  provided  that the  disclosing  party has
complied with the provisions of Clause 21.2.

      20.   Dispute Resolution:

            20.1 In the event of a dispute between supplying party and receiving
party arising in connection with this Agreement,  the parties will first attempt
to resolve the dispute informally.  If such informal efforts fail to resolve the
dispute to the  parties'  satisfaction,  senior  representatives  of each of the
parties  shall be  notified  and  shall,  within 10  Business  Days of a written
request from one party to the other, meet in a good faith effort to resolve such
dispute or difference without recourse to legal proceedings.

            20.2 If the  dispute or  difference  is not  resolved as a result of

Business  Days  from  its  conclusion)  propose  to the  other in  writing  that
structured  negotiations be entered into with the assistance of a mediator. Upon
receipt of such notice the parties to the dispute  shall each propose and select
a suitable mediator.

agreement  cannot be reached,  either of the parties may invite the  mediator to

neither  party shall be entitled to rely on such  opinion or  introduce  it into
evidence in any legal  proceedings.  If agreement still cannot be reached,  then
any  dispute or  difference  between  the parties may be referred to the courts.
Unless a party is seeking injunctive relief, no dispute shall be referred to the

Agreement  or between the  respective  parent  undertakings  of the parties (and

behalf and on behalf of each of its Affiliates  that , in agreeing to enter into
this Agreement,  it has not relied on any representation,  warranty,  collateral
contract or other assurance  (except those set out in this Agreement) and waives

contract or other assurance, provided that nothing in this Clause shall limit or
exclude any liability for fraud.

declares   that  any  term  or  provision  of  this   Agreement  is  invalid  or
unenforceable  in whole or in part,  the parties agree that the court making the
determination of invalidity or  unenforceability  shall have the power to reduce

provision,  to delete  specific  words or phrases,  or to replace any invalid or
unenforceable  term or  provision  with a term or  provision  that is valid  and
enforceable  and that comes closest to expressing the intention of the pertinent
term or provision (or to approve such  reductions,  deletions or replacements as
agreed by the parties),  and this Agreement  shall be enforceable as so modified
after the expiration of the time within which the judgment may be appealed.

      24.   Waiver:

            24.1  The  failure  of  either  party to  insist  in any one or more
instances upon strict  performance of any of the provisions of this Agreement or
to take advantage of any of its rights shall not be construed as a waiver of any
such provision or the relinquishment of any such right.

                   this agreement or the Implementation Agreements; or

               (ii)to the  extent  that such  liabilities  have been  taken into
                   account in establishing the Final Consideration; or

               (iii) any Environmental  Liabilities,  any failure or omission to
                   obtain  or  comply  with  Environmental  Authorisations,  any
                   failure or omission to comply with any Environmental  Laws or

        under  this  Clause  if the  Seller  has or  receives  knowledge  of the
        existence  of any such claim by any other means or if such  failure does
        not prejudice the Seller's ability to defend such a claim.

<PAGE>


        (b)    it  will  not  make  any  unilateral   material   change  to  the

               agreements,  with recognised trade unions,  appropriate  employee
               representatives, or the Employees.

    8.2 The Seller will procure that, on or before Completion,  the Company will

        Employment Terms.

        mean:

        8.3.1  the period of additional  notice (if any) due from the Company at
               the date such  liability  crystallises  under the  arrangement in
               force as at Completion  which is in excess of that which he would

               October 1990;

        8.3.2  the  additional   life   assurance   cover  (if  any)  under  the

               October 1990;

        8.3.3  the supplemental  retirement benefits that are in addition to the
               benefits  to  which  Mr.  Lachance  is  entitled  under  the  TAI
               Retirement Plan and the TCI Staff Employees' Pension Plan; and

        8.3.4  any other  enhancements to his terms and conditions of employment
               granted  between 25 October 1990 and  Completion and which are in
               force as at  Completion  other than those granted in the Ordinary
               Course of Business.

    8.4 The Seller will  indemnify  the  Purchaser  (for itself and as agent and
        trustee  for the  Company)  on a  continuing  basis  against any and all
        losses or liabilities, costs (including without limitation legal costs),
        charges, expenses,  actions,  proceedings,  claims and demands which the
        Purchaser  or the Company may incur and which  relate to or arise out of
        the continuation after Completion of the Supplemental Employment Terms.

    8.5 The Purchaser acknowledges and agrees that all of the funds set aside or
        due at  Completion  to be set  aside by the  Company  in  trust  for the
        purpose  of meeting  the  liability  of the  Seller  and the  Company to
        provide  supplemental  retirement  benefits for Mr Lachance will be used
        for this  purpose.  The funds  held in trust are held at  Merrill  Lynch
        Trust  Company of America  Chicago in account no.  637-95-521.  If these
        funds  have  not  been  used for this  purpose  before  Completion,  the
        Purchaser  will procure that the Company  complies  with any  directions

        the purpose of providing such benefits for Mr Lachance.

    8.6 The Seller will  indemnify  the  Purchaser  (for itself and as agent and

        losses or liabilities,  costs (including without limitation legal costs)
        charges, expenses,  actions,  proceedings,  claims and demands which the
        Purchaser  or the  Company  may  incur  as a  result  of  the  severance
        payments, pension entitlements, accelerated pension entitlements and any
        other  benefits  actually  paid  to any  employee  whose  employment  is
        terminated  after  Completion  if  and  to  the  extent  such  payments,
        entitlements  and/or  benefits  are in excess of those  which would have
        applied at any time in the period  prior to 10 September  1997  Provided
        always  that the  dismissal  which  results  in the excess  costs  being
        incurred  takes effect within four years of  Completion  and the regular

        in respect of the  relevant  employee  for at least six months  prior to

        liabilities, costs

        under  this  indemnity  must be made  within  4 years  and 3  months  of
        Completion following which this indemnity shall have no effect.

    8.7 The Seller shall not be required to make any payment under the indemnity
        set out in sub  clause 8.6  unless a draft  certificate  shall have been
        delivered to it by the Purchaser within 30 days after the date requiring
        the Seller to indemnify  the Purchaser  pursuant to  sub-clause  8.6 and
        certifying the amount payable thereunder.  In order to enable the Seller
        to review  the  certificate,  the  Purchaser  shall (to the extent it is
        permitted by law to do so) make  available and supply to the Seller and,
        at the Seller's request and expense,  the Seller's  auditors,  copies of
        all relevant  records and other working papers)  relating to the subject
        matter of the indemnity, during normal office hours.

    8.8 If the Seller  does not within 30 days after  presentation  to it of the
        draft  certificate  give notice to the Purchaser  that it disagrees with
        the certificate or any item thereof, such notice stating the reasons for
        the  disagreement  in reasonable  detail,  the draft  certificate  shall
        become final and binding on the parties for all purposes.

    8.9 If the Seller  gives a valid  notice  within  such 30 days,  the parties
        shall attempt in good faith to reach  agreement in respect  thereof and,
        if they are unable to do so within 21 days of such notification,  either
        party  may  by  notice  to  the  other  refer  the  certificate  to  the
        Independent  Accountants in accordance  with the provisions of clause 11
        of this agreement which shall apply mutatis mutandis,  references to the
        "COMPLAINANT"  being  deemed  to  be  references  to  the  "SELLER"  and
        references to the "OTHERS" being to the "PURCHASER".

   8.10 The Seller  shall pay interest at the rate of LIBOR plus 200 basis point

     10 PENSIONS

   10.1 The Purchaser  agrees to procure that the Company will,  commencing with
        the Completion Date, respect and perform the provisions of the Scheme.

   10.2 Subject to the payment of the transfer  amount,  as described below, the
        Purchaser  will  provide  retirement  benefits  for Mr J Gush and Mr S G
        Heyes  in  respect  of  their  service  with the  Company  on and  after
        Completion so that, in each case,  their total  benefits on  retirement,
        leaving  service  or  death   (inclusive  of  any  retirement   benefits
        attributable  to service up to  Completion)  are as  described  in their
        retirement  benefit profiles in the Agreed Form. The Purchaser will also
        nominate  retirement  benefits  arrangements to which a transfer payment
        can be made from the Tioxide Offshore Pension Fund.

   10.3 The Purchaser shall indemnify the Seller (for itself and its Affiliates)
        on a continuing  basis  against any and all losses,  liabilities,  costs
        (including without limitation legal costs), charges, expenses,  actions,
        proceedings,  claims and demands which the Seller or its  Affiliates may
        incur and which  relate to or arise out of any failure by the  Purchaser
        to comply with these obligations.

   10.4 The  Seller  (or  its  relevant   Affiliate)  will  use  its  reasonable
        endeavours  to procure  payment of a transfer  amount  from the  Tioxide
        Offshore Pension Fund to the arrangements nominated by the Purchaser.

   10.5 The transfer amount will be:

        10.5.1 based on  benefits  accrued  by Mr Gush and Mr  Heyes  under  the
               Tioxide  Offshore Pension Fund for service up to Completion (i.e.
               excluding  benefits earned under all other Tioxide plans in which
               they have participated); and

        10.5.2 calculated  on a past service  reserve  basis using the projected
               unit method, based on salaries projected to retirement or earlier
               date of leaving or death, using the actuarial assumptions set out
               in the actuarial  valuation of the Tioxide  Offshore Pension Fund
               as at 1 April 1997 and will be  adjusted  as agreed  between  the
               Seller and the Purchaser for the period  between  Completion  and
               the date of payment.

   10.6 If an appropriate  transfer  amount cannot be agreed within three months
        after  Completion,  either party may require the amount to be determined
        by an  independent  actuary,  to be  nominated  by the  Seller  and  the
        Purchaser  jointly,  or if they cannot  agree,  by the  President of the
        Institute of Actuaries on application by either party.  The  independent
        actuary will act as an expert and not as an arbitrator, and his decision
        will be final and  binding  on the  parties.  His costs  will be payable
        equally by the Seller and the Purchaser.

   10.7 If the trustee of the  Tioxide  Offshore  Pension  Fund does not pay the
        transfer  amount in full by a date one month  after the date on which it
        is agreed (or decided by the independent  actuary),  the Seller will pay
        to the Purchaser the amount of the shortfall by way of adjustment to the
        Final Consideration.  However, the Seller will not be required to pay an
        amount in excess of the net cost to the Purchaser or the Company  (after
        taking  account of tax) of making good the shortfall by a payment to the
        arrangements.


     11 INDEPENDENT ACCOUNTANT

   11.1 If either party wishes to refer any matter in dispute in accordance with
        the  provisions of Clause 3 or Schedule 6 for  determination  under this
        Clause it shall give notice to the other requiring the appointment of an
        independent   accounting   firm   of   international   reputation   (the
        "INDEPENDENT  ACCOUNTANT")  excluding accounting firms who have acted as
        auditors of either party or of any of their  Affiliates in the last five
        years.  If  the  parties  are  unable  to  agree  upon  the  Independent
        Accountant  within  14  days  of  such  notice,   then  the  Independent
        Accountant shall be appointed by the President for the time being of the
        Institute  of  Chartered   Accountants  in  England  and  Wales  on  the
        application of either party.

<PAGE>


   11.2 If the Independent  Accountant  delays or becomes unwilling or incapable
        of acting or if for any other reason the President for the time being of
        the Institute of Chartered  Accountants  in England and Wales thinks fit
        he may  discharge  the  Independent  Accountant  and,  in the absence of
        agreement between the parties, appoint another in its place.

   11.3 The  Independent  Accountant  shall  act  as an  expert  and  not  as an
        arbitrator and his decision shall (in the absence of manifest  error) be
        final and  binding on the  parties.  The  Independent  Accountant  shall
        afford the parties the opportunity of making written  representations to
        them and shall make its determination within 40 days of its appointment.

   11.4 The fees and expenses of the  Independent  Accountant  shall be borne by
        the parties in equal shares unless the Independent Accountant determines
        otherwise.


     12 PROTECTIVE COVENANTS

        Group will:

        (a)    for a period of five years from Completion within any part of the
               Territories  carry on or be engaged or  involved  in the Field of
               Activity  (save as the  owner  for  investment  purposes  only of
               securities   traded  on  a  recognised  stock  exchange  and  not
               exceeding one per cent. of the securities of that class); or

        (b)    without prior  approval from the  Purchaser,  for a period of two
               years  from  Completion,   directly  or  indirectly  solicit,  or
               endeavour to entice away from the Purchaser or its Affiliates any
               of the Employees.

   12.2 Each of the  restrictions  in sub-Clause 12.1 above shall be enforceable
        independently  and its  validity  shall not be  affected if the other is
        invalid.

   12.3 The Seller  acknowledges  that the  provisions  of this Clause 12 are no
        more extensive than is reasonable to protect the Company.

   12.4 Nothing in this Clause 12 or in this agreement shall prevent:

        (a)    the  Seller  or its  Affiliates  from  purchasing  shares  in any
               company or any  business  which has an  interest  in the Field of
               Activity  (the  ownership  of which  would  otherwise  contravene
               sub-Clause   12.1)   unless  the  turnover  of  such  company  or
               business in its last  accounting  year  generated by its interest
               in the Field of  Activity  was the  greater of 10 per cent of the
               aggregate  turnover  of  such  company  or  business  and  US$100
               million.  In the event that the  Seller or any of its  Affiliates
               within five years from  Completion  purchases any  corporation or
               business  which  does have  interests  in the Field of  Activity,
               the Seller or the relevant  Affiliate are  contractually  obliged
               to offer for sale such interests to DuPont.

               If DuPont does not purchase  such  interests  from the Seller (or
               its relevant  Affiliate),  the Seller (or the relevant Affiliate)
               shall,  if  DuPont  shall  fail to or does not  accept  the offer
               referred to above  within such period to which it is entitled for
               such  purpose,  within 30 days of receipt  from  DuPont of notice
               that DuPont does not intend to purchase such interests  offer for
               sale such  interests to the  Purchaser on terms which are no less
               favourable by written notice ("OFFER NOTICE").

<PAGE>

               If the Purchaser does not unconditionally purchase such interests
               from the Seller (or its relevant  Affiliates)  within a period of
               18 months after the date of the Offer Notice,  the Seller (or the
               relevant  Affiliate)  shall be free to retain such interests with
               the consent of the Purchaser (such consent not to be unreasonably
               withheld or delayed). If such consent is reasonably withheld, the
               Seller (or the relevant  Affiliate) shall use its best endeavours
               to divest such interests  within 12 months of such consent having
               been withheld; or

        (b)    the Seller or its Affiliates from carrying on or being engaged or
               involved in:

               (i) any  business  it  currently   carries  on  (other  than  the
                   Business);

               (ii)any  business  which  only  supplies  other  members  of  the
                   Seller's Group; or

               (iii) any  business  after  such  time  as the  Purchaser  or its
                   Affiliates  have ceased to carry on or be engaged or involved
                   in such business other than by way of trade sale.

        except as required by law or any competent  regulatory  body or with the

        may be, in accordance with the requirements of this Clause 15).


     16 GENERAL

   16.1 Each of the  obligations,  Warranties and  undertakings  set out in this
        agreement  which is not fully  performed at Completion  will continue in
        force after Completion.

   16.2 Unless  otherwise  expressly  stated all claims made and  payments to be
        made under this agreement  shall be made in US Dollars.  Payments to the
        Seller shall be made in  immediately  available  funds to the account of
        the Seller at such account as the Seller may notify to the Purchaser and
        to the Purchaser in immediately  available  funds to such account as the
        Purchaser  may notify to the Seller.  All payments and values under this
        agreement  shall be in US  Dollars  and where an  amount  is not  itself
        calculated in US Dollars,  it shall be converted  into US Dollars at the
        mid-market  closing  exchange  rate for that  currency  in US Dollars as
        published in the London  Edition of the  Financial  Times  published two
        Business Days prior to the date on which the relevant  payment is due or
        where no such rate is published, at the rate quoted by Citibank, N.A. at
        the close of business in London on that date. This sub-Clause  shall not
        apply to Schedule 6.

   16.3 Save as  otherwise  provided  to the  contrary in this  agreement,  each
        payment to be made under this agreement shall be made in the currency in
        which the relevant  amount is payable,  free and clear of all deductions
        or  withholdings  of any kind,  except for those required by law, and if
        any deduction or withholding  must be made by law, an additional  amount
        will be paid which is necessary to ensure that the recipient  receives a
        net amount equal to the full amount which it would have  received if the
        payment had been made without the deduction or withholding.

   16.4 None of the rights or  obligations  under this agreement may be assigned
        or  transferred  without  the  written  consent of the other  party (the
        "NON-ASSIGNING  PARTY")  other than an assignment of the rights (but not
        the obligations) to an Affiliate of the assigning party provided that:

        (a)    such assignment  shall only be permitted if the assignment has no
               adverse effect on the Non-assigning Party;

<PAGE>

        (b)    if the Affiliate to which the rights have been assigned ceases to
               be an Affiliate  of the  assigning  party,  the rights which have
               been  transferred  shall be  re-transferred  to the  party  which
               originally  assigned those rights or to another Affiliate of that
               original assigning party; and

        (c)    it shall be a condition of any such  assignment  that  reasonable
               notice  is given in  writing  to the  Non-assigning  Party of the
               proposal  to  assign  (identifying  the  rights  proposed  to  be
               assigned,  the identity of the  proposed  assignee and such other
               details   relating  thereto  as  the   Non-assigning   Party  may
               reasonably require).

   16.5 Save as otherwise  provided in this agreement,  each party shall pay the
        costs and expenses  incurred by it and its Affiliates in connection with
        the entering into and completion of this agreement.

   16.6 This  agreement  may be executed in any number of  counterparts,  all of
        which taken together shall constitute one and the same agreement and any
        party may enter into this agreement by executing a counterpart.

   16.7 No amendment,  variation or waiver of this agreement or any provision of
        this agreement shall be effective  unless it is in writing  specifically
        referring to this  agreement  and duly  executed by or on behalf of both
        parties.

   16.8 Both  parties  shall at their own  expense at all times from the date of
        this  agreement  do all things as may be required to give effect to this
        agreement including,  without limitation, the execution of all deeds and
        documents,  procuring the  convening of all meetings,  the giving of all
        waivers and consents and the passing of all  resolutions  and  otherwise
        exercising all powers and rights available to them.

   16.9 The  Seller  and the  Purchaser  agree to make a timely,  effective  and
        irrevocable  election under Section 338(h)(10) of the Code and under any
        comparable  statutes  in any  other  jurisdiction  with  respect  to the
        Company (the "SECTION 338(H)(10)  ELECTION"),  and to file such election
        in  accordance  with  applicable   regulations.   Without  limiting  the
        generality  of the  foregoing,  in order to effect  such  election,  the
        Seller and the Purchaser shall jointly  execute the necessary  copies of
        IRS Form  8023 and  attachments  required  to be  filed  therewith.  The
        Section 338(h)(10)  Election shall properly reflect the Price Allocation
        (as hereinafter defined).  Within 45 days after the Completion Date, the
        Purchaser  shall  deliver to the  Seller a  statement  (the  "ALLOCATION
        STATEMENT")  allocating  the modified  ADSP (as such terms is defined in
        Treasury  Regulations Section  1.338(h)(10)-1)  (the "MODIFIED AGGREGATE
        DEEMED  SALES  PRICE") of the assets of the Company in  accordance  with
        this Agreement and the Treasury  Regulations  promulgated  under Section
        338(h)(10).

        The Seller shall have the right to review the Allocation  Statement.  If
        within 30 days after  receipt of the  Allocation  Statement,  the Seller
        notifies the  Purchaser in writing  that the  allocation  of one or more
        items  reflected  in  the  Allocation  Statement  is  not  a  reasonable
        allocation, the Purchaser and the Seller will negotiate in good faith to
        resolve such  dispute.  If the  Purchaser and the Seller fail to resolve
        such dispute within 30 days, the Independent  Accountant shall determine
        whether the  allocation  was reasonable  and, if not  reasonable,  shall
        appropriately  revise the Allocation  Statement.  If the Seller does not
        respond within 30 days, or upon  resolution of the disputed  items,  the
        allocation  reflected on the Allocation Statement (as such may have been
        adjusted)  shall be the "PRICE  ALLOCATION"  and shall be binding on the
        parties hereto.  The Seller and the Purchaser agree to act in accordance
        with the Price  Allocation in the  preparation of financial  statements,
        filing and audit of any Tax return.

   19.2 If the courts of the State of Delaware decline jurisdiction, the English
        courts shall have exclusive  jurisdiction  for all purposes  relating to

        conventions) outside the United States of America.


    A.5 OWNERSHIP OF ASSETS

        purposes of the US Financial Information,  disposed of by the Company in

        operating the Business fully and effectively as conducted by the Company
        prior to Completion.

        factors including,  without limitation,  production schedules and market

        of the  Business for the last four  quarters.  The Stock is owned by the
        Company free and clear of all liens,  claims,  charges and  encumbrances
        other than any such liens arising by operation of law or by statute. The
        Stock is located at the  Property  and as  disclosed  in the  Disclosure
        Letter.

        assets  necessary for the Company to carry on fully and  effectively the
        Business  in the  manner  and to the  extent  to which  it is  presently
        conducted.

        and  accurate  record  and  in  the  Seller's  opinion  is  collectively
        sufficient for the purposes of conducting the Company's  business in the
        Ordinary  Course  of  Business.  The  Business  Data  and the  Company's
        information,  and the means of access to them, are exclusively  owned by
        it and under its direct control or are under its authority.

        force and effect,  all  premiums  have been duly paid and, so far as the

        comply.

        proceedings pending and no letter before action has been received by the

        the last  three  years.  There  are no  orders,  decrees,  judgments  or

        or the  Seller  (on  behalf of the  Company)  is a party or by which the

                   such authorisations.

               (b) No works or  costs  are or will be  necessary  to  obtain  or
                   secure compliance with or maintain any existing Environmental
                   Authorisations  or their  conditions  or  otherwise to comply
                   with Environmental Laws.

               (c) The Company  has  received  no  communication  in any form in
                   respect of any Environmental Authorisation varying, modifying
                   in any material respect,  revoking,  suspending or cancelling
                   the same or indicating an intention or  threatening  so to do
                   and there  are no facts or  circumstances  which  the  Seller
                   knows or ought  reasonably  to know which will  result in any
                   Environmental   Authorisation  being  so  varied,   modified,
                   revoked, suspended or which may prejudice their renewal.

                   connection with the renewal or extension of all Environmental

               (e) The  Company is not  engaged in and,  so far as the Seller is
                   aware,  there are no facts which make it likely or  desirable

                   Authorisations which have been applied for but which have not
                   yet been granted or are pending will not be granted  within a
                   reasonable  period of time and on terms which are  acceptable
                   in order for the  Company to continue  its  current  business

                   result  in any  Environmental  Authorisations  being  varied,
                   modified, revoked, suspended, cancelled or not renewed, other
                   than for reasons relating to the Purchaser or its Affiliates.

                                    J. TAXATION

                   circumstances  of which  the  Seller is aware  which  make it

                   authority  and,  so far as the Seller is aware,  there are no
                   existing  circumstances which make it likely, in the event of

                   arise.  There  are no liens  for Tax upon the  Assets  of the

                   Contamination pursuant to Environmental Laws;

                   it  is  Reasonably  Necessary  to  undertake  remediation  of
                   Environmental  Contamination,  which  would (but for the fact
                   that an  environmental  authority  is  unaware of it) be more
                   likely  than  not to  result  in an  environmental  authority
                   bringing  an  Environmental  Proceeding  under  (i)(a) in the
                   definition of Environmental Proceeding and which would result

        2.1.1  all Environmental  Liabilities arising at or from the Site(s), to

               Environmental  Laws  related  to the  operation  of  those  Sites
               which are  owned,  occupied  or used by the  Company  AT [DATE OF

        Seller nor any of its Affiliates  shall be liable under the Indemnity or
        otherwise  to  the  extent  that  such  liability   arises  from  or  is

        Liabilities  arising  at or from the  Site(s)  to the  extent  that such
        Environmental Liabilities are as a result of Environmental Contamination
        after Completion.

        Affiliates shall not be liable to the Seller under the Counter Indemnity

        Environmental  Liabilities and potential Environmental Liabilities which
        may give rise to a claim under or in connection with this
        Counter Indemnity, howsoever arising.

    3.4 The  provisions  of  sub-paragraphs  4.2 and 12.1  shall  apply  equally

               indirect)  of the  Company,  the  Purchaser  or  any  Affiliates,
               employees,   agents  or  contractors   thereof  after  Completion

               not  including  any  material   change  of  process   within  the

               mean any  failure  by the  Company  or  Purchaser  to  carry  out
               remediation or preventative  action in circumstances  where it is
               not within  their  power to do so or where the  Purchaser  is not
               aware  or  could  not   reasonably   have   been   aware  of  the
               Environmental   Liabilities   in  question   or  where   (without
               prejudice to the  obligations  of the Purchaser  under  paragraph
               5) the  rights  of the  Purchaser  to  bring  a claim  under  the
               Indemnity would be prejudiced as a result thereof.

    4.2 No  claim  may be  made  for any  Environmental  Liabilities  under  the
        Indemnity  or Counter  Indemnity  to the extent  that any  Environmental
        Liabilities arise:

        4.2.1  as a result  directly or  indirectly of  information  voluntarily
               given,  in the  case of the  Indemnity  by the  Purchaser  or the
               Company  (but only post  Completion  in the case of the  Company)
               or, in the case of the  Counter  Indemnity,  by the Seller  after
               Completion  to a  regulatory  authority  in  circumstances  other
               than  where  there is a  mandatory  reporting  requirement  under
               Environmental  Laws or where  information is given as required in
               the   context   of    applications    for   or    variations   to
               authorisations,   licences  and  other  forms  of   environmental
               consent  required by the Business in the course of the  Company's
               or the  Purchaser's or Seller's  normal  business  activities (as
               appropriate)  or where the other  party has  previously  proposed
               or approved this course of action in writing; and

        4.2.2  save where compelled by law, from any admission of liability by a
               representative of the Purchaser or Seller holding a rank not less
               than that of Senior  Vice  President  in respect of any  clean-up
               which needs to be done, except where the other party has approved
               such  admission in writing such  approval not to be  unreasonably
               withheld or delayed.

    4.3 No claim under the terms of the  Indemnity or Counter  Indemnity for any
        Environmental  Liabilities  shall be valid unless notice has been served
        in  accordance  with the  provisions  of  paragraph 7 and in the case of
        Indemnity,  but not the Counter  Indemnity,  said notice has been served
        within 10 years of Completion.

    4.4 The  Seller's   liability  under  the  Indemnity  shall  be  limited  in
        accordance  with the  provisions  of the Americas  Liability  Agreement,
        except for  sub-clauses  4.1.2 (save for the proviso to sub-clause  4.1)
        and 4.2 of the Americas Liability Agreement, the subject matter of which
        will be governed by the provisions of this Schedule.

    4.5 In the event that the  Indemnitor  (as defined in paragraph  6.1) either
        incurs external charges,  costs and expenses for environmental  services
        or internal charges for its own environmental  services,  in either case
        including but not limited to testing and/or  analytical  services and/or
        contaminated soil disposal facilities, in connection with or in relation
        to any actual or potential Environmental Liabilities under the Indemnity
        or Counter  Indemnity (as  appropriate)  then such external and internal
        charges,  costs and expenses  shall be deemed to be payments  made under
        the  Indemnity  or Counter  Indemnity  (as  appropriate).  Any  internal
        charges shall be made on the same basis as the Indemnitor charges to its
        own business or its Affiliates.

<PAGE>


    4.6 It is hereby  expressly  agreed that, save where the Seller has accepted
        liability or becomes  otherwise liable under the terms of the Indemnity,
        all costs  incurred  by the  Purchaser  in  carrying  out  environmental
        analyses and tests of the Site(s) (and its (or their)  surrounds)  shall
        be borne by the  Purchaser,  other  than  costs in the  exercise  of the
        rights and  powers  given to the  Seller by  sub-paragraphs  9.1 and 9.2
        which shall be borne by the Seller unless the Purchaser  becomes  liable
        therefor under the terms of the Counter  Indemnity or unless the parties
        otherwise agree.

    4.7 The Seller shall be liable under the Indemnity for any  asbestos-related
        personal  injury  unless and to the extent that any works carried out by
        the Purchaser or its  Affiliates or the Company after  Completion,  were
        not carried out by a reputable contractor or contractors,  who were duly
        and properly  authorised or approved to undertake such works to at least
        the  standards  of the  relevant  federal,  state  or  other  regulatory
        authorities  published  by or in  operation  (in  accordance  with  good
        industry practice) at all times during the carrying out of such works.


      5 MITIGATION

        The  Seller and the  Purchaser  shall take all  reasonable  steps  after
        Completion  to avoid or mitigate any  Environmental  Liabilities  and/or
        potential  Environmental  Liabilities  to the  extent  it is  reasonably
        within their respective  powers to do so, which may give rise to a claim
        under or in  connection  with this  Indemnity or Counter  Indemnity,  as
        appropriate, howsoever arising. Such steps will include but shall not be
        limited to:

    5.1 in  the  case  of  the   Purchaser,   carrying  out  (where   reasonably
        practicable)  appropriate  soil tests before  taking any action which is
        likely to cause a material disturbance to soil;

    5.2 in the case of the Purchaser,  where reasonably  practicable carrying on
        its  activities  on the Site(s) so as to minimise  disturbance  to known
        areas of existing or probable soil contamination  (other than deliberate
        removal of such contaminated soil) without incurring abnormal unusual or
        excessive cost in so doing;

    5.3 where  relevant,  (with  the  approval  of  the  other  party  not to be
        unreasonably  withheld  or  delayed)  settling a claim of any party (not
        being an Affiliate of the  Purchaser in the case of the  Indemnity or of
        the Seller in the case of the Counter  Indemnity) which will or may fall
        within the terms of the Indemnity or Counter Indemnity,  as appropriate,
        the costs and expenses  associated  with such settlement (so approved by
        the other party) being deemed to be  Environmental  Liabilities  for the
        purposes  of  this  agreement,  provided  always  that  nothing  in this
        sub-paragraph 5.3 shall oblige the Purchaser or the Seller to enter into
        any settlement which it does not, in its sole discretion, consider to be
        in the best interests of its operations;

    5.4 making  reasonable and timely efforts to pursue claims against any third
        parties  (including  insurers) who may have some liability in respect of
        the matter in  question  under the  Indemnity  or Counter  Indemnity  as
        appropriate  provided  always  that this shall not limit or  restrict or
        operate  in any way as a  pre-condition  to the  rights  to make a claim
        under this Indemnity or Counter Indemnity, as appropriate; and

    5.5 in the case of the Purchaser,  using reasonable endeavours to avoid acts
        or  omissions  of the  nature  described  in  sub-paragraph  4.1 of this
        Schedule.

<PAGE>

      6 Notification

    6.1 As soon as  reasonably  practicable  after either party becomes aware of
        any actual or potential Environmental Liabilities which may give rise to
        a claim by it under the Indemnity or Counter  Indemnity (the "CLAIMANT")
        (whether or not the Claimant is of the opinion that it has a valid claim
        against the other party under the  Indemnity or Counter  Indemnity  (the
        "INDEMNITOR")),  the Claimant  shall give written  notice thereof to the
        Indemnitor (and  thereafter will use all reasonable  efforts to keep the
        Indemnitor  reasonably  informed of all material  developments  relating
        thereto).  Such written notice shall include  reasonable  details of all
        relevant  matters  relating  to any  actual or  potential  Environmental
        Liabilities.   Thereafter,   the  Claimant  will  promptly   advise  the
        Indemnitor orally of the Claimant's reasonable estimate of the extent of
        and,  where  reasonably  practicable,  the  cost of  remediation  of the
        Environmental  Liabilities,  as a  result  thereof),  provided  that the
        Indemnitor  shall have given the Claimant  written notice of the name of
        its representative to whom such oral communication shall be imparted.

    6.2 Neither  party shall admit,  settle or discharge  any claim or liability
        which might  constitute a claim against the other under the Indemnity or
        Counter Indemnity (as appropriate)  without having first served a notice
        under this  paragraph 6 and given the other a reasonable  opportunity to
        consider the circumstances referred to in the said notice.


      7 CLAIMS

        In the  event  that the  Claimant  wishes  to make a claim  against  the
        Indemnitor  under the Indemnity or Counter  Indemnity  (as  appropriate)
        then it shall  do so by  giving  notice  in  writing  of the same to the
        Indemnitor  giving  such  details as are then in its  possession  of the
        relevant subject matter of such claim.


      8 CONDUCT

        If any notice is received by either  party under  paragraphs 6 or 7, the
        Claimant shall, if so requested by the Indemnitor,  take all steps which
        are necessary and  reasonable to avoid,  resist,  appeal,  compromise or
        defend any claim and any adjudication in respect thereof (subject to the
        Claimant  being  indemnified  against  all cost and  expenses  which may
        reasonably and necessarily be incurred in connection therewith), and the
        Indemnitor shall (subject to the provisions of this  paragraph),  at its
        request, be allowed to conduct any negotiations,  proceedings or appeals
        incidental  thereto  PROVIDED  ALWAYS  that if the claim  relates  to or
        arises  from a Site which at the time is owned,  occupied or used by the
        Company  and  which  is  operational  at the  date of the  notice  under
        paragraph 7 then the Purchaser  shall have conduct of all  negotiations,
        proceedings or appeals incidental thereto but shall nonetheless keep the
        Seller  fully  informed  of all  material  developments  relating to the
        subject matter of the claims.


      9 SITE ACCESS

        If any notice is received by the Seller under paragraphs 6 or 7:

    9.1 the  Seller  and/or its  agents  and  contractors  shall be free to have
        access  to any  Site(s)  to the  extent  it is  within  the power of the
        Company, the Purchaser or its Affiliates,  during normal business hours,
        and after reasonable prior notice, and, if so required by the Purchaser,
        in the presence of authorised representatives of the Purchaser to assess
        (including  but not limited to  assessment by soil sampling and testing)
        the   extent  of  the   Environmental   Liabilities   and/or   potential
        Environmental  Liabilities and to determine the action required in order
        to remediate such  liabilities  (such actions to be subject to the prior
        agreement of the Purchaser (including as to the action to be taken) such
        agreement not to be unreasonably withheld); and

    9.2 the Purchaser  shall (during normal  business hours) allow the Seller or
        its agents  access to inspect  and take copies of such books and records
        of the  business of the  Company  and/or the  Purchaser  relating to the
        Site(s)  as  may be  necessary  in  connection  with  any  Environmental
        Liabilities and/or potential Environmental Liabilities.

<PAGE>

    9.3 The Seller shall exercise  proper care in the exercise of its powers and
        rights  pursuant to this  paragraph 9 and shall  indemnify the Purchaser
        for all  reasonably  incurred  losses or  liabilities  arising  from the
        Seller's failure to do so.


     10 DISCUSSIONS

        Upon either party having given a notice under  paragraphs 6 or 7, either
        the Seller or the Purchaser may request a meeting as soon as practicable
        to  discuss  the matter  (and if either  does so the other  party  shall
        comply  promptly with such request) and,  irrespective  of whether there
        has been any agreement on liability,  each party shall be fully involved
        but (save as  otherwise  agreed  between the parties) not as to make any
        admission or liability  not  permitted by the other  provisions  of this
        Schedule in any discussions and/or  negotiations with any party imposing
        or seeking to impose any Environmental Liabilities.


     11 DISPUTE RESOLUTION

        Upon either party giving a notice in accordance with paragraph 7, in the
        event  that the Seller and the  Purchaser  are unable to agree  promptly
        upon any factual  matter  relevant to a claim  under this  Indemnity  or
        Counter  Indemnity (as  appropriate) or in the event of any other matter
        being referred to the Experts in accordance  with this Schedule then the
        following provisions of this paragraph 11 shall apply:

   11.1 a reputable  independent  firm of experts (the "EXPERTS") (who shall act
        as experts and not arbitrators) in relation to the Environment  relevant
        to the claim or  potential  claim  (having  at least ten years  relevant
        experience) shall be appointed by mutual agreement of the parties hereto
        (and the  parties  shall each be obliged  to use their  respective  best
        endeavours  to reach  agreement as soon as  practicable)  to resolve any
        factual  matter in dispute  between the parties  but not  including  any
        interpretation  of laws or  regulations  as they  apply to such  factual
        matters or any conclusions regarding  responsibility or liability for or
        in  relation to any factual  matters.  The Experts  shall be offered the
        appointment  within 15 Business Days of the parties reaching such mutual
        agreement  and  shall  be  notified  in  writing  of the  provisions  of
        sub-paragraph   11.7  below.   Failing  such  mutual  agreement  on  the
        appointment of Experts,  the parties shall promptly refer the issue,  at
        their  joint  cost,  to the  President  for the time  being of the Royal
        Institute of Chartered Surveyors in the United Kingdom with instructions
        to  appoint   suitable  Experts  within  14  days  of  receipt  of  such
        instructions;

   11.2 the said Experts shall only be dismissed by the mutual  agreement of the
        parties hereto;

   11.3 both parties shall promptly and simultaneously  exchange with each other
        and  submit  to the  Experts,  and in any event in  accordance  with the
        Experts'  written   directions,   their  arguments  and  submissions  in
        connection  with any matter of fact referred to them in accordance  with
        this paragraph 11;

   11.4 following  receipt by the  Experts of the  written  arguments  and other
        submissions of the parties pursuant to paragraph 11.3, the parties shall
        instruct  the Experts to issue,  as soon as  reasonably  practicable,  a
        formal  written  opinion  pertaining  to the matter of fact  referred to
        them. In any event,  the Experts shall be instructed to present the said
        opinion  within two months after  receiving  the written  arguments  and
        other submissions of the parties pursuant to sub-paragraph 11.3;

   11.5 the  formal  written   opinion  of  the  Experts   issued   pursuant  to
        sub-paragraph  11.4 shall be conclusive in any  proceedings  between the
        parties hereto as to the question of fact so determined;

   11.6 the fees and  expenses  of the  Experts  shall be borne  equally  by the
        Seller and the Purchaser (unless otherwise directed by the Experts); and

<PAGE>

   11.7 the Experts,  and any company,  firm,  partnership or other organisation
        with  which the  Experts  are  connected,  shall not be  eligible  to be
        considered  to undertake  any clean-up  work in respect of the claim for
        which they have so acted on or around the Site(s) save where the parties
        hereto  mutually  agree to waive this  provision.  For the  avoidance of
        doubt, either party may withhold such consent in any event.


     12 ACCEPTANCE OF LIABILITY

        In the event that the Seller  admits  that it has any  liability  to the
        Purchaser  under the Indemnity (or where the Seller agrees to accept the
        Purchaser's  claim as falling within the Indemnity  notwithstanding  the
        fact  that no  Environmental  Liability  may at that  point in time have
        arisen):

   12.1 Subject to consulting with and paying  reasonable regard to the views of
        the  Purchaser,  the  Seller  shall  have  the  right  independently  to
        determine  whatever  measures  are  appropriate  in order  to  remediate
        pursuant to  applicable  Environmental  Laws the  subject  matter of the
        claim under the  Indemnity  and  furthermore  the Seller  shall have the
        right  independently  to carry out such  remediation  itself (or through
        suitable  third party agents or  contractors)  provided that in so doing
        the Seller (or its said agents or  contractors)  shall be obliged to use
        reasonable endeavours to avoid causing undue interruption to the conduct
        of the business of the Company and/or its Affiliates;

   12.2 The Seller and/or its agents and  contractors  shall, in addition to the
        rights of access  provided  for in  paragraph  9 above,  be free to have
        access to the Site(s) if  currently  owned,  leased or, where within the
        power of the Company and its  Affiliates,  during normal  business hours
        after  reasonable prior notice,  and if so required,  in the presence of
        authorised   representatives   of  the  Purchaser,   to  carry  out  the
        remediation  referred to in  sub-paragraph  12.1 above provided that the
        Seller (or its agents or contractors) shall be obliged to use reasonable
        endeavours  to avoid causing  undue  interruption  to the conduct of the
        business of the Company and/or its Affiliates.

   12.3 The Seller shall exercise  reasonable care in the exercise of its powers
        and rights  pursuant to this paragraph 12 and shall exercise  reasonable
        skill,  care and  diligence  in carrying out any works and shall not use
        any materials  which are not in accordance with the  recommendations  of
        relevant  authorities  and codes of practice.  The Seller shall  procure
        that the contractors and consultants  engaged to carry out and advise on
        the works  are  bound by  obligations  in the same  terms of  reasonable
        skill,  care and  diligence as herein  before  mentioned  and  otherwise
        engaged  on  market  terms  at  the  time  and  shall  procure  suitable
        warranties  in accordance  with normal market  practice at the time from
        the contractors  and consultants om favour of the Purchaser.  The Seller
        shall not carry out the works  itself but shall always  engage  external
        contractors and consultants  approved by the Purchaser such approval not
        to be unreasonably withheld or delayed.


     13 STATEMENTS

        In the event of any  circumstances  arising which do or may give rise to
        Environmental  Liabilities  which  may  fall  within  the  terms  of the
        Indemnity or the Counter Indemnity (as appropriate) neither the Company,
        the Purchaser nor the Seller (nor any of their respective Affiliates) to
        the extent  practicable  shall make any public  statements  which is not
        required  by law or  the  rules  of any  regulatory  authority  to  make
        regarding such  circumstances  without first  discussing  with the other
        party  and  reaching  written   agreement  (such  agreement  not  to  be
        unreasonably  withheld  or  delayed)  on the  text  of any  such  public
        statement before it is made.
<PAGE>


     14 GENERAL

   14.1 Any  information,  records,  or other  material  of one  party  shall be
        treated as strictly  confidential  by the other party except when (a) it
        is  required to be used in order to comply with an order of the court or
        regulatory authority or (b) it is used by the other party to enforce its
        rights under this Schedule or so as to make an insurance  claim provided
        that, in the case of either (a) or (b), disclosure is made in accordance
        with this sub-paragraph  14.1. If either party becomes legally compelled
        (including  by   deposition,   interrogatory,   request  for  documents,
        subpoena, civil investigative demand or similar process) to disclose any
        of the  information,  records,  or other  material  referred  to in this
        sub-paragraph  14.1, the party so compelled shall provide the other with
        prompt prior written  notice of such  requirement  so that the other may
        seek a  protective  order or other  appropriate  remedy.  To the  extent
        lawfully  able to do so, each party  agrees to cooperate in each other's
        efforts to obtain a protective order or other reasonable  assurance that
        confidential  treatment shall be accorded any such information.  If such
        protective order or other remedy is not obtained, the party so compelled
        agrees to disclose  only that portion of the  information,  records,  or
        other  material  which it is advised  by  opinion of outside  counsel is
        legally  required to be disclosed  and to take all  reasonable  steps to
        preserve  the  confidentiality  of the  information,  records,  or other
        material referred to in this sub-paragraph 14.1. Any other disclosure by
        one party of information,  records or materials of the other party shall
        require the prior written  consent of such other party,  which shall not
        be unreasonably withheld or delayed.

   14.2 The Purchaser's and its Affiliates' and the Seller's and its Affiliates'
        exclusive  remedies in respect of any claims which fall within the scope
        of the  Indemnity  or Counter  Indemnity,  as  appropriate,  shall be in
        accordance  with the provisions of this  Schedule,  and the Purchaser on
        behalf of itself and its Affiliates and the Seller,  on behalf of itself
        and  its  Affiliates,  hereby  waives  all  other  remedies  whether  in
        contract,  tort (including,  for the avoidance of doubt,  negligence) or
        howsoever  otherwise arising which it may have against the Seller or any
        of  its  Affiliates  or the  Purchaser  or  any  of  its  Affiliates  as
        appropriate  at law or in equity in  respect of the  matters  which fall
        within the scope of the  Indemnity or Counter  Indemnities  and, for the
        avoidance of doubt,  if such a claim under this Schedule could also give
        rise to a Warranty  Claim or a claim under any other  provision  of this
        agreement in respect of the same subject  matter,  the  Purchaser or the
        Seller as appropriate may only bring a claim under this Schedule.

   14.3 The Seller  undertakes to  co-operate  with the Purchaser and assist the
        Purchaser in achieving a transfer to the Purchaser (or as it directs) of
        all  Environmental  Authorisations,  Permits  and  licences  held by the
        Seller at Completion.


     15 CO-OPERATION

        The Purchaser  undertakes that wherever  co-operation is required by the
        Company to ensure compliance with the Purchaser's obligations hereunder,
        the  Purchaser  will use its  reasonable  endeavours  to ensure that the

               the following formula:

               Final  Consideration  = EV  minus  AND  minus  NWC 28  plus  ANWC
               (excluding in relation to any of the foregoing any item or matter
               attributable to the LPC  Interests)_plus  in the case only of TAI
               LV

<PAGE>

               Where (in relation to the Company):

               EV = Enterprise Value

               AND = Actual Net Debt

               NWC28 = Net Working Capital as at 28 February 1998

               ANWC = Actual Net Working Capital

               LV = US$176,222,000 (value of LPC Interests)

        (b)    After  the   Completion   Date,   the  Seller  shall   prepare  a
               completion  statement  as at  the  Completion  Date  which  shall
               contain a  statement  of the Final  Consideration  in  accordance
               with  paragraph  3(a) above  based on the  Seller's  calculations
               (the  "FINAL   COMPLETION   STATEMENT").   The  Final  Completion
               Statement   shall  be   prepared   using  the   Seller's   normal
               accounting  policies  and  practices as set out or referred to in
               ICI's  Controller's  Manuals  as  applied  by  the  Company  on a
               consistent  basis and  shall be  submitted  by the  Seller to the
               Seller's  Auditors  for review.  Taxation  paid or payable by the
               Company  (including  any sum paid or  payable  to a member of the
               Seller's  Group  in  respect  of  Taxation)  as a  result  of the
               transfer  of  the  Sale  Shares  to  the   Purchaser   (including
               Taxation  paid or  payable by the  Seller  under  Clause 5 of the
               Tax Deed of  Covenant)  shall not be taken  into  account  in the
               calculation of the Final Consideration.

    (4) Within 45 days of the Completion  Date, the Seller shall issue the Final
        Completion  Statement  (distinguishing  between the LPC Business and the
        other business of the Company) for the Company to the Purchaser together
        with a copy of a report by the Seller's Auditors addressed to the Seller
        and  substantially in the form set out in Annex 3 to the effect that the
        Final  Completion  Statement has been  prepared in accordance  with this
        agreement.  Although it is the  Seller's  responsibility  to prepare the
        Final  Completion  Statement,  the Seller will require the assistance of
        the  employees  of the  relevant  Purchaser  Affiliates  to fulfil  this
        responsibility  and  the  Purchaser  shall  ensure  such  assistance  is
        provided  promptly and at no charge.  Immediately  after delivery of the
        Final  Completion  Statement,  the  Purchaser's  Auditors shall have the
        right,  subject to the Purchaser  delivering to the Sellers'  Auditors a
        signed  letter  in the  form set out in Annex  5, to  review  the  Final
        Completion  Statement and the Seller's  Auditors working papers relating
        to the Final  Completion  Statement.  Within 45 days of  delivery to the
        Purchaser of the Final  Completion  Statement and the Seller's  Auditors
        report (each of which shall be in English) to the Purchaser's designated
        location,  the  Purchaser  shall give notice to the Seller in writing of
        any item or items in the Final  Completion  Statement which they wish to
        dispute and the basis on which they dispute that item or those items and
        the  changes  to the Final  Completion  Statement  which  the  Purchaser
        believes  should be made and the  parties  shall  use  their  reasonable
        endeavors  to resolve  that  dispute.  Any items in respect of which the
        Purchaser does not give such notice will be deemed to have been accepted
        by the Purchaser.  Any written  resolution reached by the parties on any
        disputed item shall be final, conclusive and binding on the parties.

    (5) If the parties agree the Final  Completion  Statement then any adjusting
        payments  referred to in paragraph (7) below shall be made by the paying
        party within 7 days of being agreed by the parties.

    (6) If the  parties  fail to agree on any  element  of the Final  Completion
        Statement within 14 days after the Purchaser has given notice in writing
        to the Seller of any item(s) in the Final Completion Statement which the
        Purchaser  wishes to dispute (in  accordance  with  paragraph (4) above)
        then any agreed  amounts shall be paid in accordance  with the preceding
        paragraph  and any dispute  may be  referred  by either  party for final
        determination  in accordance  with sub-Clause 11.1 of this agreement and
        any  amounts  thereby  found  to be due  shall  be paid by the  relevant
        Affiliate not later than 7 days after such final determination.

<PAGE>


    (7) When the  Final  Consideration  is  agreed or  otherwise  determined  in
        accordance with the three preceding  paragraphs the following  adjusting
        payments shall be made:

        (a)    an  amount  equal to the  difference  between  (i) the  Estimated
               Consideration and (ii) the Final Consideration; and

        (b)    interest  (compounded monthly) at the Interest Rate on the amount
               in paragraph  (a) above from the  Completion  Date to the date of
               payment, calculated on a day to day basis;

        which shall be paid by the Seller  Affiliate to the  Purchaser  (or vice
        versa, as appropriate).

    (8) In this Schedule, references to lines of A Forms have been chosen by the
        Seller and are  believed in good faith to  correspond  to the matters to
        which they refer.  If,  however,  that  reference  when  compared to the
        matter it  describes  or  refers to is  incorrect  then  there  shall be
        substituted  for that line  reference to another line reference (if any)
        which corresponds to the matter described or referred to.

        NOTES:

      1 Pension Liability (Approx.  US$250,000) is accounted for according to US
        rules  (FAS87  etc.)  in A Form.  Therefore  no  reconciling  difference
        between US and UK GAAP.

      2 ICI A Forms  do not  report  deferred  tax for  ICI's  US  subsidiaries.
        However any deferred tax in the US GAAP  accounts is readily  analysable
        into its LPC and  Sulphate  and is  estimated to derive to the extent of
        some 99 per cent. from LPC's tax depreciation.

               (i) save  as  may  be  set  out  in  this  agreement  or  in  the

                   connection   with  this   agreement  or  the   Implementation
                   Agreements; and

               (ii)any claim by the Purchaser or any person  deriving title from
                   it in connection with the Warranties  shall be subject to the
                   following provisions of this Clause.

    5.4 The  liability of the Seller in respect of any breach of the  Warranties

               (i) to the extent  that the claim  arises as a result only of any

                   was specifically  consented to in writing by the Purchaser in
                   the  knowledge  that  such  matter  would  give  rise to such
                   Warranty Claim.

        agreement after Completion in any circumstances provided that nothing in

        for fraud.

    5.9 Save as otherwise  provided in this  agreement,  the Seller shall not be
        liable in respect of any Warranty Claim to the extent that the liability
        of the Seller in respect thereof is incurred or increased as a result of
        any  legislation not brought into force at the date of this agreement or
        as a result of any change in or repeal of legislation  hereafter or as a
        result of the  introduction  or cessation of or change in the  published

                   respect of which any such claim or alleged claim arises) have
                   been fairly disclosed in the Disclosure Letter; or

               (ii)such  claim  arises  or  is  incurred  as  a  result  of  any
                   voluntary  act or omission of the  Purchaser or any Affiliate
                   of the Purchaser  after the date of this agreement other than
                   any such act or omission  which is in the ordinary  course of

                   binding  commitment  of  the  Company  or any  member  of the

                   this agreement or the Implementation Agreements; or

               (ii)to the  extent  that such  liabilities  have been  taken into
                   account in establishing the Final Consideration; or

               (iii) any Environmental  Liabilities,  any failure or omission to
                   obtain  or  comply  with  Environmental  Authorisations,  any
                   failure or omission to comply with any Environmental  Laws or
                   any claim by any person in  respect of any matter  concerning

        give such notice shall not abrogate or diminish the Seller's  obligation
        under  this  Clause  if the  Seller  has or  receives  knowledge  of the
        existence  of any such claim by any other means or if such  failure does

        years from the Completion Date, will procure that:



<PAGE>


        (a)    the Employees will receive and enjoy contractual remuneration and
               benefits  (including  separation and other benefits  described in
               the Disclosure  Letter) which,  judged  objectively,  are no less
               favourable  overall  than  their  contractual   remuneration  and
               benefits at the Completion Date; and

        (b)    it  will  not  make  any  unilateral   material   change  to  the
               contractual terms and conditions of employment with the Employees
               without prior  consultation  and  concurrence  as required by any
               local  laws  or  agreements,   with   recognised   trade  unions,
               appropriate employee representatives, or the Employees.

    8.2 The Seller will procure that, on or before Completion,  the Company will
        discharge its  liability to Mr. Guy Gauthier in respect of  Supplemental
        Employment Terms.

    8.3 For the purposes of this clause,  "SUPPLEMENTAL  EMPLOYMENT TERMS" shall
        mean:

        8.3.1  the period of additional  notice (if any) due from the Company at
               the date such  liability  crystallises  under the  arrangement in
               force as at Completion  which is in excess of that which he would
               have received under the terms of his service  agreement  dated 25
               October 1990;

        8.3.2  the supplemental  retirement benefits that are in addition to the
               benefits to which Mr.  Gauthier  is entitled  under the TCI Staff
               Employees' Pension Plan; and

        8.3.3  any other  enhancements to his terms and conditions of employment
               granted  between 25 October 1990 and  Completion and which are in
               force as at  Completion  other than those granted in the Ordinary
               Course of Business.

    8.4 The Seller will  indemnify  the  Purchaser  (for itself and as agent and
        trustee  for the  Company)  on a  continuing  basis  against any and all
        losses or liabilities, costs (including without limitation legal costs),
        charges, expenses,  actions,  proceedings,  claims and demands which the
        Purchaser  or the Company may incur and which  relate to or arise out of
        the continuation after Completion of the Supplemental Employment Terms.

    8.5 The  Purchaser  acknowledges  and agrees that all of the funds set aside
        (or due at  Completion  to be set  aside) by the  Company  (in trust and
        including  related  refundable tax amounts with Revenue  Canada) for the
        purpose  of meeting  the  liability  of the  Seller  and the  Company to
        provide  supplemental  retirement benefits for Mr. Gauthier will be used
        for  this  purpose.  The  funds  held in trust  are held at Royal  Trust
        Company 1 Place Ville Marie Montreal in account nos.  554114673-001  and
        554 831932.  If these funds have not been used for this  purpose  before
        Completion,  the Purchaser  will procure that the Company  complies with
        any  directions  given by the Seller as to the use of these  funds after
        Completion for the purpose of providing such benefits for Mr. Gauthier.

    8.6 The Seller will  indemnify  the  Purchaser  (for itself and as agent and
        trustee  for the  Company)  on a  continuing  basis  against any and all
        losses or liabilities,  costs (including without limitation legal costs)
        charges, expenses,  actions,  proceedings,  claims and demands which the
        Purchaser  or the  Company  may  incur  as a  result  of  the  severance
        payments, pension entitlements, accelerated pension entitlements and any
        other  benefits  actually  paid  to any  employee  whose  employment  is
        terminated  after  Completion  if  and  to  the  extent  such  payments,
        entitlements  and/or  benefits  are in excess of those  which would have
        applied at any time in the period  prior to 10 September  1997  Provided
        always  that the  dismissal  which  results  in the excess  costs  being
        incurred  takes effect within four years of  Completion  and the regular
        salary figure used in the  calculations is one which has been prevailing
        in respect of the  relevant  employee  for at least six months  prior to
        termination.   This  indemnity   shall  not  extend  to  any  losses  or
        liabilities,  costs (including  without limitation legal costs) charges,
        expenses, actions,  proceedings,  claims and demands which the Purchaser
        or the  Company  may  incur as a result  of its or their  negligence  or
        default. Any claims under this indemnity must be made within 4 years and
        3 months of  Completion  following  which this  indemnity  shall have no
        effect.

    8.7 The Seller shall not be required to make any payment under the indemnity
        set out in sub  clause 8.6  unless a draft  certificate  shall have been
        delivered to it by the Purchaser within 30 days after the date requiring
        the Seller to indemnify  the Purchaser  pursuant to  sub-clause  8.6 and
        certifying the amount payable thereunder.  In order to enable the Seller
        to review  the  certificate,  the  Purchaser  shall (to the extent it is
        permitted by law to do so) make  available and supply to the Seller and,
        at the Seller's request and expense,  the Seller's  auditors,  copies of
        all relevant  records and other working papers)  relating to the subject
        matter of the indemnity, during normal office hours.

    8.8 If the Seller  does not within 30 days after  presentation  to it of the
        draft  certificate  give notice to the Purchaser  that it disagrees with
        the certificate or any item thereof, such notice stating the reasons for
        the  disagreement  in reasonable  detail,  the draft  certificate  shall
        become final and binding on the parties for all purposes.

    8.9 If the Seller  gives a valid  notice  within  such 30 days,  the parties
        shall attempt in good faith to reach  agreement in respect  thereof and,
        if they are unable to do so within 21 days of such notification,  either
        party  may  by  notice  to  the  other  refer  the  certificate  to  the
        Independent  Accountants in accordance  with the provisions of clause 11
        of this agreement which shall apply mutatis mutandis,  references to the

        references to the "OTHERS" being to the "PURCHASER".

   8.10 The Seller  shall pay interest at the rate of LIBOR plus 200 basis point
        compounded monthly on all payments pursuant to this clause from the date
        of delivery of the draft certificate.

     12 PROTECTIVE COVENANTS

        The Seller  covenants  with the Purchaser that no member of the Seller's
        Group will:

        (a)    for a period of five years from Completion within any part of the
               Territories  carry on or be engaged or  involved  in the Field of
               Activity  (save as provided in  sub-Clause  12.4 below and as the
               owner for  investment  purposes  only of  securities  traded on a
               recognised  stock exchange and not exceeding one per cent. of the
               securities of that class); or

        (b)    without prior  approval from the  Purchaser,  for a period of two
               years  from  Completion,   directly  or  indirectly  solicit,  or
               endeavour to entice away from the Purchaser or its Affiliates any
               of the Employees.

   12.1 Each of the  restrictions  in sub-Clause 12.1 above shall be enforceable
        independently  and its  validity  shall not be  affected if the other is
        invalid.

   12.2 The Seller  acknowledges  that the  provisions  of this Clause 12 are no
        more extensive than is reasonable to protect the Company.

   12.3 Nothing in this Clause 12 or in this agreement shall prevent:

        (a)    the  Seller  or its  Affiliates  from  purchasing  shares  in any
               company or any  business  which has an  interest  in the Field of
               Activity  (the  ownership  of which  would  otherwise  contravene
               sub-Clause   12.1)   unless  the  turnover  of  such  company  or
               business in its last  accounting  year  generated by its interest
               in the Field of  Activity  was the  greater of 10 per cent of the
               aggregate  turnover  of  such  company  or  business  and  US$100
               million.  In the event that the  Seller or any of its  Affiliates

               to offer for sale such interests to DuPont.

<PAGE>


               If DuPont does not purchase  such  interests  from the Seller (or
               its relevant  Affiliate),  the Seller (or the relevant Affiliate)
               shall,  if  DuPont  shall  fail to or does not  accept  the offer

               that DuPont does not intend to purchase such interests  offer for
               sale such  interests to the  Purchaser on terms which are no less
               favourable by written notice ("OFFER NOTICE").

               If the Purchaser does not unconditionally purchase such interests
               from the Seller (or its relevant  Affiliates)  within a period of
               18 months after the date of the Offer Notice, then the Seller (or
               the relevant  Affiliate)  shall be free to retain such  interests
               with  the  consent  of  the  Purchaser  (such  consent  not to be
               unreasonably  withheld or delayed). If such consent is reasonably
               withheld,  then the Seller (or the relevant  Affiliate) shall use
               its best endeavours to divest such interests  within 12 months of
               such consent having been withheld; or

        (b)    the Seller or its Affiliates from carrying on or being engaged or
               involved in:

               (i) any  business  it  currently   carries  on  (other  than  the
                   Business);

               (ii)any  business  which  only  supplies  other  members  of  the
                   Seller's Group; or

               (iii) any  business  after  such  time  as the  Purchaser  or its
                   Affiliates  have ceased to carry on or be engaged or involved
                   in such business other than by way of trade sale; or


     13 ANNOUNCEMENTS

        required  by law or any  competent  regulatory  body or with  the  prior

   16.1 Each of the  obligations,  Warranties and  undertakings  set out in this
        agreement  which is not fully  performed at Completion  will continue in
        force after Completion.

   16.2 Unless  otherwise  expressly  stated all claims made and  payments to be
        made under this agreement  shall be made in US Dollars.  Payments to the
        Seller shall be made in  immediately  available  funds to the account of
        the Seller at such account as the Seller may notify to the Purchaser and
        to the Purchaser in immediately  available  funds to such account as the
        Purchaser  may notify to the Seller.  All payments and values under this
        agreement  shall be in US  Dollars  and where an  amount  is not  itself
        calculated in US Dollars,  it shall be converted  into US Dollars at the
        mid-market  closing  exchange  rate for that  currency  in US Dollars as
        published in the London  Edition of The  Financial  Times  published two
        Business Days prior to the date on which the relevant  payment is due or
        where no such rate is published, at the rate quoted by Citibank, N.A. at
        the close of business in London on that date.
        This sub-Clause shall not apply to Schedule 6.



<PAGE>


   16.3 Save as  otherwise  provided  to the  contrary in this  agreement,  each
        payment to be made under this agreement shall be made in the currency in
        which the relevant  amount is payable,  free and clear of all deductions
        or  withholdings  of any kind,  except for those required by law, and if
        any deduction or withholding  must be made by law, an additional  amount
        will be paid which is necessary to ensure that the recipient  receives a
        net amount equal to the full amount which it would have  received if the
        payment had been made without the deduction or withholding.

   16.4 None of the rights or  obligations  under this agreement may be assigned
        or  transferred  without the written  consent of the other  parties (the
        "NON-ASSIGNING PARTIES") other than an assignment of the rights (but not
        the obligations) to an Affiliate of the assigning party provided that:

        (a)    such assignment  shall only be permitted if the assignment has no
               adverse effect on the Non-assigning Parties;

        (b)    if the Affiliate to which the rights have been assigned ceases to
               be an Affiliate  of the  assigning  party,  the rights which have
               been  transferred  shall be  re-transferred  to the  party  which
               originally  assigned those rights or to another Affiliate of that
               original assigning party; and

        (c)    it shall be a condition of any such  assignment  that  reasonable
               notice is given in  writing to the  Non-assigning  Parties of the
               proposal  to  assign  (identifying  the  rights  proposed  to  be
               assigned,  the identity of the  proposed  assignee and such other
               details  relating  thereto  as  the  Non-assigning   Parties  may
               reasonably require).

   16.5 Save as otherwise  provided in this agreement,  each party shall pay the
        costs and expenses  incurred by it and its Affiliates in connection with
        the entering into and completion of this agreement.

   16.6 This  agreement  may be executed in any number of  counterparts,  all of
        which taken together shall constitute one and the same agreement and any
        party may enter into this agreement by executing a counterpart.

   16.7 No amendment,  variation or waiver of this agreement or any provision of
        this agreement shall be effective  unless it is in writing  specifically
        referring to this  agreement  and duly  executed by or on behalf of each
        party.

   16.8 Each party shall at their own expense at all times from the date of this
        agreement  do all  things  as may be  required  to give  effect  to this
        agreement including,  without limitation, the execution of all deeds and
        documents,  procuring the  convening of all meetings,  the giving of all
        waivers and consents and the passing of all  resolutions  and  otherwise
        exercising all powers and rights available to them.

        or between  the  respective  parent  undertakings  of the  parties  (and

        this  agreement and which extends or  supplements  any provision in this
        agreement  will be deemed for the purposes of  sub-Clause  17.1 above to
        form part of the whole  agreement  between the parties as referred to in
        that sub-Clause.

        on behalf of each of its Affiliates that, in agreeing to enter into this
        agreement and the  Implementation  Agreements,  it has not relied on any
        representation, warranty, collateral contract or other assurance (except
        those set out in this  agreement)  and waives  all  rights and  remedies
        which,  but for this  sub-Clause,  might otherwise be available to it in
        respect of any such  representation,  warranty,  collateral  contract or
        other  assurance,  provided  that  nothing in this Clause shall limit or
        exclude any liability for fraud.

        debentures or other securities of the Company.


    A.3 OWNERSHIP OF THE SALE SHARES

    (1) The Seller is the sole legal and  beneficial  owner of the Sale  Shares.
        The Sale  Shares  constitute  the  entire  issued  share  capital of the
        Company.

    (2) The Seller is  entitled  to sell and  procure  the  transfer of the full
        legal  and  beneficial  ownership  in the  Sale  Shares  free  from  any
        encumbrance,  equity  or  third  party  right  of  any  kind  or  nature
        whatsoever,  from any  agreement  or contract to grant the same and from
        any claim to any of the same.

    (3) The Sale  Shares  are fully  paid up or  credited  as fully  paid up and
        constitute  the whole of the issued and allotted  share capital owned by
        the Seller in the Company.

    (4) No agreement  or contract  has been  entered into which  requires or may
        require the Company to allot or issue any share or loan  capital and the
        Company has not allotted or issued any securities  which are convertible
        into share or loan  capital and there are no voting  trusts,  proxies or
        other  agreements  or  understandings  with respect to the voting of the
        Sale Shares.

        consortium (other than recognised trade associations).

    (3) The  Company   does  not  have  any  place  of  business  or   permanent
        establishment   (as  that  expression  is  defined  in  double  taxation
        conventions) outside Canada.


    A.5 OWNERSHIP OF ASSETS

    (1) Except for those Assets that are leased (as described in the  Disclosure
        Letter),  the Company has full legal and beneficial  title to all Assets
        (whether  tangible or  intangible)  reflected in the Accounts  (save for
        current  assets and fixed  assets  worth less than  US$100,000,  both as
        defined for the purposes of the Accounts,  disposed of by the Company in
        the Ordinary  Course of its Business since the  Accounting  Date) and to
        all assets acquired by the Company since 28 February 1998.

    (2) None of the  Assets is subject to any  encumbrance  (including,  without

        lien  arising  by  operation  of law or by  statute),  deposit by way of
        security,  bill of sale,  option or right of  pre-emption)  except those
        that arise in the Ordinary Course of Business and do not have a material
        adverse  effect  on the  Business.  All  significant  items of Plant and
        Equipment  have been  regularly  and  adequately  maintained  where such
        maintenance  is normally  required and are in  reasonable  working order
        having  regard to their age and use and taken as a whole are  capable of
        operating the Business fully and effectively as conducted by the Company
        prior to Completion.



<PAGE>

        factors including,  without limitation,  production schedules and market
        demand  (including  seasonal  factors  affecting the same) the Stocks in
        aggregate comprise broadly the same mix of products as has been required
        and has been maintained at levels  sufficient to meet the level of sales
        of the  Business for the last four  quarters.  The Stock is owned by the
        Company free and clear of all liens,  claims,  charges and  encumbrances
        other than any such liens arising by operation of law or by statute. The
        Stock is located at the Tracy Site and as  disclosed  in the  Disclosure
        Letter.

    (4) The  Company  owns or has the right to use all the  property  rights and
        assets  necessary for the Company to carry on fully and  effectively the
        Business  in the  manner in and to the  extent to which it is  presently
        conducted.

    (5) The  Business  Data taking into  account the time,  purpose,  nature and
        context in which it was prepared is in all material respects a bona fide
        and  accurate  record  and  in  the  Seller's  opinion  is  collectively
        sufficient for the purposes of conducting the Company's  business in the
        Ordinary  Course  of  Business.  The  Business  Data  and the  Company's
        information,  and the means of access to them, are exclusively  owned by
        it and under its direct control or are under its authority.

    (6) The  Disclosure   Letter  contains  details  of  the  current  insurance
        arrangements  applicable to the Company.  Those arrangements are in full
        force and effect,  all  premiums  have been duly paid and, so far as the
        Seller is aware, nothing has been done or omitted to be done which would
        make any policy of insurance  of the Company void or voidable.  There is
        no claim outstanding under any such arrangement.


    A.6 COMPLIANCE WITH STATUTES

        The Company has complied  with all  applicable  laws  (including  rules,
        regulations  both  having  the  force  of law,  injunctions,  judgments,
        orders,  decrees,  rulings, and charges thereunder) of national,  local,
        and foreign governments (and all agencies thereof), and no action, suit,
        proceeding, hearing, investigation, charge, claim, demand, or notice has
        been filed or commenced  against the Company  alleging any failure so to
        comply.

        complied  with in all material  respects.  The Company has paid all fees
        due under the same. A list of material  Permits has been  disclosed  and

        shareholder.

        in excess of US$100,000 or which  otherwise will have a material  effect
        on the  operation  of the Company and the Business and there are no such
        proceedings pending and no letter before action has been received by the
        Company and so far as the Seller is aware  there are no facts  likely to

        Disclosure Letter a list (which is complete and accurate in all material
        respects)  which includes a description of each pending law suit,  claim
        (including    customer    complaints),    administrative    proceedings,
        arbitration,  labour dispute or governmental investigation or inspection
        to  which  the  Company  is a party or  involves  the  operation  of the
        Business or involves the Sale Shares and in each case which is likely to
        involve the Company claiming or paying sums in excess of US$100,000. The
        Seller has disclosed  all material  (individually  or in the  aggregate)
        product liability claims received by the Company or by the Seller during
        the last  three  years.  There  are no  orders,  decrees,  judgments  or
        agreements with any court or governmental authority to which the Company
        or the  Seller  (on  behalf of the  Company)  is a party or by which the
        Company or the Seller or the Sale Shares are bound and which will have a
        material effect on the operation of the Company and its business.

<PAGE>

    (2) No  administrator,  receiver  or  administrative  receiver  or any other

        Company nor has any such order been made.

        Company.

                   can continue to comply in the future with all  conditions  of
                   such authorisations.

               (b) No works or  costs  are or will be  necessary  to  obtain  or
                   secure compliance with or maintain any existing Environmental
                   Authorisations  or their  conditions  or  otherwise to comply
                   with Environmental Laws.

               (c) The Company  has  received  no  communication  in any form in
                   respect of any Environmental Authorisation varying, modifying
                   in any material respect,  revoking,  suspending or cancelling
                   the same or indicating an intention or  threatening  so to do
                   and there  are no facts or  circumstances  which  the  Seller
                   knows or ought  reasonably  to know which will  result in any
                   Environmental   Authorisation  being  so  varied,   modified,
                   revoked, suspended or which may prejudice their renewal.

                   connection with the renewal or extension of all Environmental
                   Authorisations.

               (e) The  Company is not  engaged in and,  so far as the Seller is
                   aware,  there are no facts which make it likely or  desirable
                   that it should be  engaged  in any  appeal in  respect of any
                   Environmental   Authorisation  or  any  conditions  contained
                   therein or any refusal of any Environmental Authorisation.

               (f) So far as the Seller is aware or ought to be aware,  there is
                   no reason  (other than reasons  relating to the  Purchaser or
                   its   Affiliates)   to  believe   that  those   Environmental
                   Authorisations which have been applied for but which have not
                   yet been granted or are pending will not be granted  within a
                   reasonable  period of time and on terms which are  acceptable
                   in order for the  Company to continue  its  current  business
                   operations.

               (g) So far as the  Seller  is aware or  ought  to be  aware,  the
                   execution and/or  performance of this agreement and all other
                   documents  which are to be  executed at  Completion  will not
                   result  in any  Environmental  Authorisations  being  varied,
                   modified, revoked, suspended, cancelled or not renewed, other
                   than for reasons relating to the Purchaser or its Affiliates.

                   it  is  Reasonably  Necessary  to  undertake  remediation  of
                   Environmental  Contamination,  which  would (but for the fact
                   that an  environmental  authority  is  unaware of it) be more
                   likely  than  not to  result  in an  environmental  authority
                   bringing  an  Environmental  Proceeding  under  (i)(a) in the
                   definition of Environmental Proceeding and which would result

               (iii) notwithstanding  sub-paragraph 4.1 hereafter, any agreement
                   by the  Purchaser  or its  Affiliates  with an  environmental
                   authority that the Purchaser or its Affiliates will undertake
                   remediation   of   Environmental    Contamination   if   such
                   remediation is required by such environmental  authority as a
                   condition  to the  granting,  surrender  or  variation  of an
                   Environmental  Authorisation  relating to the Site,  provided
                   that:

                   (a)the grant,  surrender or  variation  of the  Environmental
                      Authorisation  arises out of the  conduct of the  Business
                      by the Purchaser or its Affiliates; and

<PAGE>

                   (b)the subject matter of the agreement with the environmental
                      authority  shall relate to the Site  Provided  that if the
                      subject  matter of the  agreement  does not  relate to the
                      Site, the Purchaser shall have taken all such steps as may
                      be  reasonable  to  contest  the  relevant   environmental
                      authorities linkage of the subject matter of the agreement
                      to the Site; and

                   (c)the  remediation  is not required  because of any proposed

                      Company; and

                      Site or part  thereof,  the  remediation  is not  required
                      because  of any  proposed  closure  of all or  part of the
                      Site, other than in relation to:

                      (I) any  material  change of process  within the  existing
                          plant and/or buildings on such Site; or

                      (II)any material  change to or development of the business
                          and/or  operations  carried  on at the Site which does
                          not  result in such Site (or any part)  ceasing  to be
                          used for  general  industrial/manufacturing  of a type

        Affiliates shall not be liable to the Seller under the Counter Indemnity

               Environmental   Liabilities   in  question   or  where   (without
               prejudice to the  obligations  of the Purchaser  under  paragraph
               5) the  rights  of the  Purchaser  to  bring  a claim  under  the
               Indemnity would be prejudiced as a result thereof.

    4.2 No  claim  may be  made  for any  Environmental  Liabilities  under  the
        Indemnity  or Counter  Indemnity  to the extent  that any  Environmental
        Liabilities arise:

        4.2.1  as a result  directly or  indirectly of  information  voluntarily
               given,  in the  case of the  Indemnity  by the  Purchaser  or the
               Company  (but only post  Completion  in the case of the  Company)
               or, in the case of the  Counter  Indemnity,  by the Seller  after
               Completion  to a  regulatory  authority  in  circumstances  other
               than  where  there is a  mandatory  reporting  requirement  under
               Environmental  Laws or where  information is given as required in
               the   context   of    applications    for   or    variations   to
               authorisations,   licences  and  other  forms  of   environmental
               consent  required by the Business in the course of the  Company's
               or the  Purchaser's or Seller's  normal  business  activities (as
               appropriate)  or where the other  party has  previously  proposed
               or approved this course of action in writing; and

        4.2.2  save where compelled by law, from any admission of liability by a
               representative of the Purchaser or Seller holding a rank not less
               than that of Senior  Vice  President  in respect of any  clean-up
               which needs to be done, except where the other party has approved
               such  admission in writing such  approval not to be  unreasonably
               withheld or delayed.

    4.3 No claim under the terms of the  Indemnity or Counter  Indemnity for any
        Environmental  Liabilities  shall be valid unless notice has been served
        in  accordance  with the  provisions  of  paragraph 7 and in the case of
        Indemnity,  but not the Counter  Indemnity,  said notice has been served
        within 10 years of Completion.

    4.4 The  Seller's   liability  under  the  Indemnity  shall  be  limited  in
        accordance  with the  provisions  of the Americas  Liability  Agreement,
        except for  sub-clauses  4.1.2 (save for the proviso to sub-clause  4.1)
        and 4.2 of the Americas Liability Agreement, the subject matter of which
        will be governed by the provisions of this Schedule.

    4.5 In the event that the  Indemnitor  (as defined in paragraph  6.1) either
        incurs external charges,  costs and expenses for environmental  services
        or internal charges for its own environmental  services,  in either case
        including but not limited to testing and/or  analytical  services and/or
        contaminated soil disposal facilities, in connection with or in relation
        to any actual or potential Environmental Liabilities under the Indemnity
        or Counter  Indemnity (as  appropriate)  then such external and internal
        charges,  costs and expenses  shall be deemed to be payments  made under
        the  Indemnity  or Counter  Indemnity  (as  appropriate).  Any  internal
        charges shall be made on the same basis as the Indemnitor charges to its
        own business or its Affiliates.

    4.6 It is hereby  expressly  agreed that, save where the Seller has accepted
        liability or becomes  otherwise liable under the terms of the Indemnity,
        all costs  incurred  by the  Purchaser  in  carrying  out  environmental
        analyses and tests of the Site(s) (and its (or their)  surrounds)  shall
        be borne by the  Purchaser,  other  than  costs in the  exercise  of the
        rights and  powers  given to the  Seller by  sub-paragraphs  9.1 and 9.2
        which shall be borne by the Seller unless the Purchaser  becomes  liable
        therefor under the terms of the Counter  Indemnity or unless the parties
        otherwise agree.

    4.7 The Seller shall be liable under the Indemnity for any  asbestos-related
        personal  injury  unless and to the extent that any works carried out by
        the Purchaser or its  Affiliates or the Company after  Completion,  were
        not carried out by a reputable contractor or contractors,  who were duly
        and properly  authorised or approved to undertake such works to at least
        the standards of the relevant  federal,  provincial or other  regulatory
        authorities  published  by or in  operation  (in  accordance  with  good
        industry practice) at all times during the carrying out of such works.

      5 MITIGATION

        The  Seller and the  Purchaser  shall take all  reasonable  steps  after
        Completion  to avoid or mitigate any  Environmental  Liabilities  and/or
        potential  Environmental  Liabilities  to the  extent  it is  reasonably
        within their respective  powers to do so, which may give rise to a claim
        under or in  connection  with this  Indemnity or Counter  Indemnity,  as
        appropriate, howsoever arising. Such steps will include but shall not be
        limited to:

    5.1 in  the  case  of  the   Purchaser,   carrying  out  (where   reasonably
        practicable)  appropriate  soil tests before  taking any action which is
        likely to cause a material disturbance to soil;

    5.2 in the case of the Purchaser,  where reasonably  practicable carrying on
        its  activities  on the Site(s) so as to minimise  disturbance  to known
        areas of existing or probable soil contamination  (other than deliberate
        removal of such contaminated soil) without incurring abnormal unusual or
        excessive cost in so doing;

    5.3 where  relevant,  (with  the  approval  of  the  other  party  not to be
        unreasonably  withheld  or  delayed)  settling a claim of any party (not
        being an Affiliate of the  Purchaser in the case of the  Indemnity or of
        the Seller in the case of the Counter  Indemnity) which will or may fall
        within the terms of the Indemnity or Counter Indemnity,  as appropriate,
        the costs and expenses  associated  with such settlement (so approved by
        the other party) being deemed to be  Environmental  Liabilities  for the
        purposes  of  this  agreement,  provided  always  that  nothing  in this
        sub-paragraph 5.3 shall oblige the Purchaser or the Seller to enter into
        any settlement which it does not, in its sole discretion, consider to be
        in the best interests of its operations;

    5.4 making  reasonable and timely efforts to pursue claims against any third
        parties  (including  insurers) who may have some liability in respect of
        the matter in  question  under the  Indemnity  or Counter  Indemnity  as
        appropriate  provided  always  that this shall not limit or  restrict or
        operate  in any way as a  pre-condition  to the  rights  to make a claim
        under this Indemnity or Counter Indemnity, as appropriate; and

    5.5 in the case of the Purchaser,  using reasonable endeavours to avoid acts
        or  omissions  of the  nature  described  in  sub-paragraph  4.1 of this
        Schedule.


      6 NOTIFICATION

    6.1 As soon as  reasonably  practicable  after either party becomes aware of
        any actual or potential Environmental Liabilities which may give rise to
        a claim by it under the Indemnity or Counter  Indemnity (the "CLAIMANT")
        (whether or not the Claimant is of the opinion that it has a valid claim
        against the other party under the  Indemnity or Counter  Indemnity  (the
        "INDEMNITOR")),  the Claimant  shall give written  notice thereof to the
        Indemnitor (and  thereafter will use all reasonable  efforts to keep the
        Indemnitor  reasonably  informed of all material  developments  relating
        thereto).  Such written notice shall include  reasonable  details of all
        relevant  matters  relating  to any  actual or  potential  Environmental
        Liabilities.   Thereafter,   the  Claimant  will  promptly   advise  the
        Indemnitor orally of the Claimant's reasonable estimate of the extent of
        and,  where  reasonably  practicable,  the  cost of  remediation  of the
        Environmental  Liabilities,  as a  result  thereof),  provided  that the
        Indemnitor  shall have given the Claimant  written notice of the name of
        its representative to whom such oral communication shall be imparted.

    6.2 Neither  party shall admit,  settle or discharge  any claim or liability
        which might  constitute a claim against the other under the Indemnity or
        Counter Indemnity (as appropriate)  without having first served a notice
        under this  paragraph 6 and given the other a reasonable  opportunity to
        consider the circumstances referred to in the said notice.

<PAGE>

      7 CLAIMS

        In the  event  that the  Claimant  wishes  to make a claim  against  the
        Indemnitor  under the Indemnity or Counter  Indemnity  (as  appropriate)
        then it shall  do so by  giving  notice  in  writing  of the same to the
        Indemnitor  giving  such  details as are then in its  possession  of the
        relevant subject matter of such claim.


      8 CONDUCT

        If any notice is received by either  party under  paragraphs 6 or 7, the
        Claimant shall, if so requested by the Indemnitor,  take all steps which
        are necessary and  reasonable to avoid,  resist,  appeal,  compromise or
        defend any claim and any adjudication in respect thereof (subject to the
        Claimant  being  indemnified  against  all cost and  expenses  which may
        reasonably and necessarily be incurred in connection therewith), and the
        Indemnitor shall (subject to the provisions of this  paragraph),  at its
        request, be allowed to conduct any negotiations,  proceedings or appeals
        incidental  thereto  PROVIDED  ALWAYS  that if the claim  relates  to or
        arises  from a Site which at the time is owned,  occupied or used by the
        Company  and  which  is  operational  at the  date of the  notice  under
        paragraph 7 then the Purchaser  shall have conduct of all  negotiations,
        proceedings or appeals incidental thereto but shall nonetheless keep the
        Seller  fully  informed  of all  material  developments  relating to the
        subject matter of the claims.


      9 SITE ACCESS

        If any notice is received by the Seller under paragraphs 6 or 7:

    9.1 the  Seller  and/or its  agents  and  contractors  shall be free to have
        access  to any  Site(s)  to the  extent  it is  within  the power of the
        Company, the Purchaser or its Affiliates,  during normal business hours,
        and after reasonable prior notice, and, if so required by the Purchaser,
        in the presence of authorised representatives of the Purchaser to assess
        (including  but not limited to  assessment by soil sampling and testing)
        the   extent  of  the   Environmental   Liabilities   and/or   potential
        Environmental  Liabilities and to determine the action required in order
        to remediate such  liabilities  (such actions to be subject to the prior
        agreement of the Purchaser (including as to the action to be taken) such
        agreement not to be unreasonably withheld); and

    9.2 the Purchaser  shall (during normal  business hours) allow the Seller or
        its agents  access to inspect  and take copies of such books and records
        of the  business of the  Company  and/or the  Purchaser  relating to the
        Site(s)  as  may be  necessary  in  connection  with  any  Environmental
        Liabilities and/or potential Environmental Liabilities.

    9.3 The Seller shall exercise  proper care in the exercise of its powers and
        rights  pursuant to this  paragraph 9 and shall  indemnify the Purchaser
        for all  reasonably  incurred  losses or  liabilities  arising  from the
        Seller's failure to do so.


     10 DISCUSSIONS

        Upon either party having given a notice under  paragraphs 6 or 7, either
        the Seller or the Purchaser may request a meeting as soon as practicable
        to  discuss  the matter  (and if either  does so the other  party  shall
        comply  promptly with such request) and,  irrespective  of whether there
        has been any agreement on liability,  each party shall be fully involved
        but (save as  otherwise  agreed  between the parties) not as to make any
        admission or liability  not  permitted by the other  provisions  of this
        Schedule in any discussions and/or  negotiations with any party imposing
        or seeking to impose any Environmental Liabilities.

<PAGE>

     11 DISPUTE RESOLUTION

        Upon either party giving a notice in accordance with paragraph 7, in the
        event  that the Seller and the  Purchaser  are unable to agree  promptly
        upon any factual  matter  relevant to a claim  under this  Indemnity  or
        Counter  Indemnity (as  appropriate) or in the event of any other matter
        being referred to the Experts in accordance  with this Schedule then the
        following provisions of this paragraph 11 shall apply:

   11.1 a reputable  independent  firm of experts (the "EXPERTS") (who shall act
        as experts and not arbitrators) in relation to the Environment  relevant
        to the claim or  potential  claim  (having  at least ten years  relevant
        experience) shall be appointed by mutual agreement of the parties hereto
        (and the  parties  shall each be obliged  to use their  respective  best
        endeavours  to reach  agreement as soon as  practicable)  to resolve any
        factual  matter in dispute  between the parties  but not  including  any
        interpretation  of laws or  regulations  as they  apply to such  factual
        matters or any conclusions regarding  responsibility or liability for or
        in  relation to any factual  matters.  The Experts  shall be offered the
        appointment  within 15 Business Days of the parties reaching such mutual
        agreement  and  shall  be  notified  in  writing  of the  provisions  of
        sub-paragraph   11.7  below.   Failing  such  mutual  agreement  on  the
        appointment of Experts,  the parties shall promptly refer the issue,  at
        their  joint  cost,  to the  President  for the time  being of the Royal
        Institute of Chartered Surveyors in the United Kingdom with instructions
        to  appoint   suitable  Experts  within  14  days  of  receipt  of  such
        instructions;

   11.2 the said Experts shall only be dismissed by the mutual  agreement of the
        parties hereto;

   11.3 both parties shall promptly and simultaneously  exchange with each other
        and  submit  to the  Experts,  and in any event in  accordance  with the
        Experts'  written   directions,   their  arguments  and  submissions  in
        connection  with any matter of fact referred to them in accordance  with
        this paragraph 11;

   11.4 following  receipt by the  Experts of the  written  arguments  and other
        submissions of the parties pursuant to paragraph 11.3, the parties shall
        instruct  the Experts to issue,  as soon as  reasonably  practicable,  a
        formal  written  opinion  pertaining  to the matter of fact  referred to
        them. In any event,  the Experts shall be instructed to present the said
        opinion  within two months after  receiving  the written  arguments  and
        other submissions of the parties pursuant to sub-paragraph 11.3;

   11.5 the  formal  written   opinion  of  the  Experts   issued   pursuant  to
        sub-paragraph  11.4 shall be conclusive in any  proceedings  between the
        parties hereto as to the question of fact so determined;

   11.6 the fees and  expenses  of the  Experts  shall be borne  equally  by the
        Seller and the Purchaser (unless otherwise directed by the Experts); and

   11.7 the Experts,  and any company,  firm,  partnership or other organisation
        with  which the  Experts  are  connected,  shall not be  eligible  to be
        considered  to undertake  any clean-up  work in respect of the claim for
        which they have so acted on or around the Site(s) save where the parties
        hereto  mutually  agree to waive this  provision.  For the  avoidance of
        doubt, either party may withhold such consent in any event.


     12 ACCEPTANCE OF LIABILITY

        In the event that the Seller  admits  that it has any  liability  to the
        Purchaser  under the Indemnity (or where the Seller agrees to accept the
        Purchaser's  claim as falling within the Indemnity  notwithstanding  the
        fact  that no  Environmental  Liability  may at that  point in time have
        arisen):

   12.1 Subject to consulting with and paying  reasonable regard to the views of
        the  Purchaser,  the  Seller  shall  have  the  right  independently  to
        determine  whatever  measures  are  appropriate  in order  to  remediate
        pursuant to  applicable  Environmental  Laws the  subject  matter of the
        claim under the  Indemnity  and  furthermore  the Seller  shall have the
        right  independently  to carry out such  remediation  itself (or through
        suitable  third party agents or  contractors)  provided that in so doing
        the Seller (or its said agents or  contractors)  shall be obliged to use
        reasonable endeavours to avoid causing undue interruption to the conduct
        of the business of the Company and/or its Affiliates;

<PAGE>

   12.2 The Seller and/or its agents and  contractors  shall, in addition to the
        rights of access  provided  for in  paragraph  9 above,  be free to have
        access to the Site(s) if  currently  owned,  leased or, where within the
        power of the Company and its  Affiliates,  during normal  business hours
        after  reasonable prior notice,  and if so required,  in the presence of
        authorised   representatives   of  the  Purchaser,   to  carry  out  the
        remediation  referred to in  sub-paragraph  12.1 above provided that the
        Seller (or its agents or contractors) shall be obliged to use reasonable
        endeavours  to avoid causing  undue  interruption  to the conduct of the
        business of the Company and/or its Affiliates.

   12.3 The Seller shall exercise  reasonable care in the exercise of its powers
        and rights  pursuant to this paragraph 12 and shall exercise  reasonable
        skill,  care and  diligence  in carrying out any works and shall not use
        any materials  which are not in accordance with the  recommendations  of
        relevant  authorities  and codes of practice.  The Seller shall  procure
        that the contractors and consultants  engaged to carry out and advise on
        the works  are  bound by  obligations  in the same  terms of  reasonable
        skill,  care and  diligence as herein  before  mentioned  and  otherwise
        engaged  on  market  terms  at  the  time  and  shall  procure  suitable
        warranties  in accordance  with normal market  practice at the time from
        the contractors  and consultants in favour of the Purchaser.  The Seller
        shall not carry out the works  itself but shall always  engage  external
        contractors and consultants  approved by the Purchaser such approval not
        to be unreasonably withheld or delayed.


     13 STATEMENTS

        In the event of any  circumstances  arising which do or may give rise to
        Environmental  Liabilities  which  may  fall  within  the  terms  of the
        Indemnity or the Counter Indemnity (as appropriate) neither the Company,
        the Purchaser nor the Seller (nor any of their respective Affiliates) to
        the extent  practicable  shall make any public  statements which are not
        required  by law or  the  rules  of any  regulatory  authority  to  make
        regarding such  circumstances  without first  discussing  with the other
        party  and  reaching  written   agreement  (such  agreement  not  to  be
        unreasonably  withheld  or  delayed)  on the  text  of any  such  public
        statement before it is made.


     14 GENERAL

   14.1 Any  information,  records,  or other  material  of one  party  shall be
        treated as strictly  confidential  by the other party except when (a) it
        is  required to be used in order to comply with an order of the court or
        regulatory authority or (b) it is used by the other party to enforce its
        rights under this Schedule or so as to make an insurance  claim provided
        that, in the case of either (a) or (b), disclosure is made in accordance
        with this sub-paragraph  14.1. If either party becomes legally compelled
        (including  by   deposition,   interrogatory,   request  for  documents,
        subpoena, civil investigative demand or similar process) to disclose any
        of the  information,  records,  or other  material  referred  to in this
        sub-paragraph  14.1, the party so compelled shall provide the other with
        prompt prior written  notice of such  requirement  so that the other may
        seek a  protective  order or other  appropriate  remedy.  To the  extent
        lawfully  able to do so, each party  agrees to cooperate in each other's
        efforts to obtain a protective order or other reasonable  assurance that
        confidential  treatment shall be accorded any such information.  If such
        protective order or other remedy is not obtained, the party so compelled
        agrees to disclose  only that portion of the  information,  records,  or
        other  material  which it is advised  by  opinion of outside  counsel is
        legally  required to be disclosed  and to take all  reasonable  steps to
        preserve  the  confidentiality  of the  information,  records,  or other
        material referred to in this sub-paragraph 14.1. Any other disclosure by
        one party of information,  records or materials of the other party shall
        require the prior written  consent of such other party,  which shall not
        be unreasonably withheld or delayed.

<PAGE>

   14.2 The Purchaser's and its Affiliates' and the Seller's and its Affiliates'
        exclusive  remedies in respect of any claims which fall within the scope
        of the  Indemnity  or Counter  Indemnity,  as  appropriate,  shall be in
        accordance  with the provisions of this  Schedule,  and the Purchaser on
        behalf of itself and its Affiliates and the Seller,  on behalf of itself
        and  its  Affiliates,  hereby  waives  all  other  remedies  whether  in
        contract,  tort (including,  for the avoidance of doubt,  negligence) or
        howsoever  otherwise arising which it may have against the Seller or any
        of  its  Affiliates  or the  Purchaser  or  any  of  its  Affiliates  as
        appropriate  at law or in equity in  respect of the  matters  which fall
        within the scope of the  Indemnity or Counter  Indemnities  and, for the
        avoidance of doubt,  if such a claim under this Schedule could also give
        rise to a Warranty  Claim or a claim under any other  provision  of this
        agreement in respect of the same subject  matter,  the  Purchaser or the
        Seller as appropriate may only bring a claim under this Schedule.

   14.3 The Seller  undertakes to  co-operate  with the Purchaser and assist the
        Purchaser in achieving a transfer to the Purchaser (or as it directs) of
        all Environmental Authorisations held by the Seller at Completion.


     15 CO-OPERATION

        The Purchaser  undertakes that wherever  co-operation is required by the
        Company to ensure compliance with the Purchaser's obligations hereunder,
        the  Purchaser  will use its  reasonable  endeavours  to ensure that the
        Company provides the requisite co-operation.

                             CONSIDERATION ADJUSTMENT TEXT

                                      (Clause 3.3)

               with  paragraph  3(a) above  based on the  Seller's  calculations

               Statement   shall  be   prepared   using  the   Seller's   normal
               accounting  policies  and  practices as set out or referred to in

               consistent  basis and  shall be  submitted  by the  Seller to the
               Seller's Auditors for review.

    (4) Within 45 days of the Completion  Date, the Seller shall issue the Final

        copy of a report by the  Seller's  Auditors  addressed to the Seller and

        Final  Completion  Statement has been  prepared in accordance  with this
        agreement.  Although it is the  Seller's  responsibility  to prepare the
        Final  Completion  Statement,  the Seller will require the assistance of
        the  employees  of the  relevant  Purchaser  Affiliates  to fulfil  this
        responsibility  and  the  Purchaser  shall  ensure  such  assistance  is
        provided  promptly and at no charge.  Immediately  after delivery of the
        Final  Completion  Statement,  the  Purchaser's  Auditors shall have the
        right,  subject to the Purchaser  delivering to the Sellers'  Auditors a
        signed  letter  in the  form set out in Annex  5, to  review  the  Final
        Completion  Statement and the Seller's  Auditors working papers relating
        to the Final  Completion  Statement.  Within 45 days of  delivery to the
        Purchaser of the Final  Completion  Statement and the Seller's  Auditors
        report (each of which shall be in English) to the Purchaser's designated
        location,  the  Purchaser  shall give notice to the Seller in writing of
        any item or items in the Final  Completion  Statement which they wish to
        dispute and the basis on which they dispute that item or those items and
        the  changes  to the Final  Completion  Statement  which  the  Purchaser
        believes  should be made and the  parties  shall  use  their  reasonable
        endeavors  to resolve  that  dispute.  Any items in respect of which the
        Purchaser does not give such notice will be deemed to have been accepted
        by the Purchaser.  Any written  resolution reached by the parties on any
        disputed item shall be final, conclusive and binding on the parties.

    (5) If the parties agree the Final  Completion  Statement then any adjusting
        payments  referred to in paragraph (7) below shall be made by the paying
        party within 7 days of being agreed by the parties.

    (6) If the  parties  fail to agree on any  element  of the Final  Completion
        Statement within 14 days after the Purchaser has given notice in writing
        to the Seller of any item(s) in the Final Completion Statement which the
        Purchaser  wishes to dispute (in  accordance  with  paragraph (4) above)
        then any agreed  amounts shall be paid in accordance  with the preceding
        paragraph  and any dispute  may be  referred  by either  party for final
        determination  in accordance  with sub-Clause 11.1 of this agreement and
        any  amounts  thereby  found  to be due  shall  be paid by the  relevant
        Affiliate not later than 7 days after such final determination.

    (7) When the  Final  Consideration  is  agreed or  otherwise  determined  in
        accordance with the three preceding  paragraphs the following  adjusting
        payments shall be made:

        (a)    an  amount  equal to the  difference  between  (i) the  Estimated
               Consideration and (ii) the Final Consideration; and



<PAGE>


        (b)    interest  (compounded monthly) at the Interest Rate on the amount
               in paragraph  (a) above from the  Completion  Date to the date of
               payment, calculated on a day to day basis;

        which shall be paid by the Seller  Affiliate to the  Purchaser  (or vice
        versa, as appropriate).

    (8) In this Schedule, references to lines of A Forms have been chosen by the
        Seller and are  believed in good faith to  correspond  to the matters to
        which they refer.  If,  however,  that  reference  when  compared to the
        matter it  describes  or  refers to is  incorrect  then  there  shall be
        substituted  for that line  reference to another line reference (if any)
        which corresponds to the matter described or referred to.

        Affiliates.  In this respect,  the Purchaser has agreed on behalf of the

        connection  with the  Agreements  shall be  limited as set forth in this
        agreement. Accordingly, the Purchaser hereby agrees to procure that each
        of the Purchaser  Companies and any third party  claiming or acting with
        the consent of or at the behest of, through, in the name or on behalf of
        the Purchaser  Companies  (whether by right of subrogation or otherwise)
        shall  strictly  adhere  to and  comply  with  the  provisions  of  this
        agreement as if they were each a party hereto.

    2.2 If and to the extent that any of the  Purchaser  Companies or such third
        parties  fail,  omit or decline to so adhere  and comply  (for  whatever
        reason)  the  Purchaser  hereby  covenants  with ICI (for the benefit of

        expenses (including reasonable  professional fees), losses,  liabilities
        and  penalties  suffered or incurred by the ICI Companies as a result of
        and in connection with such non-adherence or non-compliance.

      3 Limitation of ICI Companies' Liability


<PAGE>

    3.1 It is hereby agreed that the ICI  Companies  shall have no liability for
        any  Claim  (other  than  Benefit  Claims  and  Acquisition   Separation
        Programme Claims):

        3.1.1  unless  the  amount of such  Claim or  alleged  Claim  exceeds US
               $100,000 (the "Qualifying Amount"); and

        3.1.2  until and to the extent only that the aggregate liability for all
               Claims exceeding the Qualifying Amount (notified previously or at
               the same time) exceeds US $1.4 million (the "Threshold Amount").

        For the avoidance of doubt, notwithstanding that the aggregate liability
        of the ICI Companies for Claims exceeding the relevant Qualifying Amount
        has exceeded the Threshold  Amount,  the ICI  Companies  shall be liable
        solely for that excess.

    3.2 Subject to Clause 4.1.1, it is hereby agreed that the maximum  aggregate
        liability  of the ICI  Companies  in respect of all Claims  (other  than
        Benefit  Claims)  shall  under no  circumstances  exceed an amount to be
        determined as follows (the "Cap"):

        3.2.1  in respect of Claims  notified to the ICI  Companies  pursuant to
               the Agreements  and/or this agreement in the period commencing on
               the Completion Date up to but not including the third anniversary
               thereof, the Cap shall be US $25,000,000;

        3.2.2  on the third  anniversary  of the  Completion  Date the Cap shall
               reduce to US $17,500,000;

        3.2.3  on the fourth and each  subsequent  anniversary of the Completion
               Date  the  Cap  shall   reduce   (but  so  that  the   applicable
               anniversary  date for  determining  whether a Claim is subject to
               a Cap  reduction as  aforesaid  shall be by reference to the date
               upon which the Claim is  notified to the ICI  Companies  pursuant
               to the  Agreements  and/or this  agreement  and not the date upon
               which  liability  thereunder  is accepted or  adjudicated)  by an
               amount of US  $2,500,000  such that on the tenth  anniversary  of
               the Completion Date it is completely extinguished;

        3.2.4  the ICI Companies  shall have no liability for any Claim notified
               by the Purchaser  Companies on or after the tenth  anniversary of
               the Completion Date.

    3.3 In no circumstances  whatsoever shall the maximum aggregate liability of
        the ICI Companies in respect of all Claims exceed US $25,000,000.

    3.4 Subject to the obligations as to  notification in Clause 4.1.1,  but not
        the time limits for notification, it is hereby agreed that:

               (i) the  maximum  aggregate  liability  of the ICI  Companies  in
                   respect of all Benefit  Claims  shall under no  circumstances
                   exceed US$10,000,000; and

               (ii)the  maximum  aggregate  liability  of the ICI  Companies  in
                   respect of all Acquisition  Separation  Claims shall under no
                   circumstances exceed US$2,500,000.

    3.5 All monetary amounts  expressed in US Dollars in this agreement shall be
        calculated  after  converting  all relevant  monetary  amounts under the
        Agreements  which are not in US Dollars to US Dollars at the  mid-market
        closing exchange rate in London for amounts of that size as published in
        the London  Edition of the Financial  Times  published two Business Days
        prior to the  date  any  Claim is  formally  notified  by the  Purchaser
        Companies  in  accordance  with  the  terms of the  relevant  Agreements
        (and/or this agreement), or where no such rate is published, at the rate
        quoted by  Citibank,  N.A.  at the close of  business  in London on that
        date.

      4 MITIGATION OF CLAIMS

    4.1 The Purchaser  Companies shall take all reasonable steps to mitigate any
        loss which may give rise to a Claim against the ICI Companies including,
        without limiting the generality of the foregoing,  the making of a claim
        which is  available  to the  Purchaser  Companies  under  any  available
        insurance policy. It is agreed that:

        4.1.1  no Claim by the  Purchaser  Companies  in  respect of a breach of
               the warranties under the Agreements  shall be enforceable  unless
               written notice thereof  (including all material  details  thereof
               then  reasonably  available to the Purchaser  Companies) has been
               given by the  Purchaser  Companies  to the ICI  Companies as soon
               as  reasonably  practicable  after the Purchaser  Companies  have
               become aware of the facts and  circumstances  giving rise to such
               Claim and their  implications  for the purposes of the  Agreement
               in question,  unless such written  notice has been duly served on
               the ICI  Companies  on or  before  [30 April  2001(1)/2002(2)] or
               by close of business on the date six years  after  the end of the
               accounting  period  ending after the  Completion  Date in respect
               of a Tax Claim;

        4.1.2  no other Claims by the Purchaser  Companies  shall be enforceable
               unless  written notice  thereof  (including all material  details
               thereof or relating  thereto  then  reasonably  available  to the
               Purchaser  Companies  has been given by the  Purchaser  Companies
               to the  ICI  Companies  (in  accordance  with  the  terms  of the
               Agreement in question) as soon as  reasonably  practicable  after
               the  Purchaser  Companies  have  become  aware of the  facts  and
               circumstances  giving  rise to the Claim  and their  implications
               for the purposes of the Agreement in question;

        Provided however that the Purchaser Companies shall be able to bring any
        Claim  against the ICI  Companies  without  complying  with the terms of
        sub-Clauses  4.1.1 and 4.1.2 hereof to the extent that the ICI Companies
        have not suffered  prejudice as a result of any such  non-compliance  by
        the Purchaser Companies.

    4.2 If any claim is made against the Purchaser  Companies the subject matter
        of which might  reasonably  be expected to constitute a breach of one or
        more  of the  Agreements  by the  ICI  Companies  save  for  indemnities
        contained  in the Tax Deeds of  Covenant  or  environmental  indemnities
        contained in the relevant  Agreements  in relation to which the specific
        provisions set out in the relevant Agreement or Deed shall apply:

        4.2.1  the Purchaser  Companies  shall if so requested in writing by the
               ICI Companies  take all steps which are necessary and  reasonable
               to avoid,  resist,  appeal,  compromise  or defend any such claim
               and any  adjudication  in  respect  thereof  (but  subject in any
               such case to the Purchaser  Companies  being  indemnified  by the
               ICI  Companies  against  all  costs  and  expenses  which  may be
               incurred in connection  therewith)  and the ICI Companies  shall,
               at  their  request,  be  allowed  to  conduct  any  negotiations,
               proceedings   or  appeals   incidental   thereto   with   counsel
               reasonably satisfactory to the Relevant Purchaser;

        4.2.2  the ICI  Companies  shall  raise no  objection  to the  Purchaser
               Companies  attending  (and,  where the  rights  of the  Purchaser
               Companies  are,  or  may  be,   detrimentally   affected)   being
               separately  legally  represented  (at  their  own  expense)  and,
               where  appropriate,  heard at any  negotiations,  proceedings  or
               appeals of which the ICI  Companies  have taken  conduct  and the
               Purchaser  Companies  shall  be  consulted  by the ICI  Companies
               prior to any  compromise,  settlement  or  admission of liability
               being   made  by  the   ICI   Companies   at  such   negotiation,
               proceedings or appeals; and

<PAGE>

        4.2.3  the Purchaser  Companies  shall at all reasonable  times and upon
               reasonable  prior  notice  allow  the  ICI  Companies  and  their
               agents  reasonable  access  to  all  relevant  properties  of the
               Relevant  Purchaser,  and  access  to,  with the right to inspect
               and take  copies  of,  all  relevant  books  and  records  of the
               Relevant  Purchaser  (as  then  carried  on)  subject  always  to
               keeping   the  same   confidential   other  than  in  respect  of
               necessary   disclosures  in  connection  with  such  Claim  which
               disclosures  shall  only be  made,  and then  only in  compliance
               with  sub-Clause  4.2.4,  if required by law or the procedures of
               any  court  or  tribunal  or  otherwise  with the  prior  written
               consent of the relevant  Purchaser  Companies  (such  consent not
               to be unreasonably withheld or delayed).

        4.2.4  If any of the  ICI  Companies  or  their  agents  become  legally
               compelled  (including by deposition,  interrogatory,  request for
               documents,   subpoena,  civil  investigative  demand  or  similar
               process) to disclose any of the  information,  records,  or other
               material   referred  to  in  this  Clause  4.2.3,  the  party  so
               compelled  shall  provide  the  Relevant  Purchaser  with  prompt
               prior  written  notice of such  requirement  so that the Relevant
               Purchaser  may  seek a  protective  order  or  other  appropriate
               remedy.  So  far  as  it  is  legally  able  so to  do,  the  ICI
               Companies   agree  to  cooperate  in  the  Relevant   Purchaser's
               efforts  to  obtain  a  protective   order  or  other  reasonable
               assurance  that  confidential  treatment  shall be  accorded  any
               such  information.  If such  protective  order or other remedy is
               not  obtained,  the party so  compelled  agrees to disclose  only
               that  portion  of the  information,  records,  or other  material
               which it is advised  by  opinion  of  outside  counsel is legally
               required  to be  disclosed  and to take all  reasonable  steps to
               preserve the  confidentiality  of the  information,  records,  or
               other material referred to in this sub-Clause 4.2.4.

        4.2.5  Notwithstanding  the  foregoing  provisions,  should the  subject
               matter of any litigation, proceeding, negotiation, or arbitration
               include a claim against the Relevant Purchaser seeking injunctive
               relief,  the  Relevant  Purchaser  shall  have the  right to take
               exclusive  control of the defence of such proceeding with counsel
               of its choice, the reasonable fees and expenses of which shall be
               for the account of the ICI Companies.

        4.2.6  The   party   or   parties   conducting   the   defence   of  any
               investigation,    litigation,   proceedings,    negotiations   or
               arbitration   shall  keep  the  other  parties  apprised  of  all
               significant   developments   and  shall   not   enter   into  any
               settlement,  compromise  or consent to judgment  with  respect to
               such  investigation,  litigation,  proceedings,  negotiations  or
               arbitration  unless the other party  consents,  such  consent not
               to be unreasonably withheld or delayed.

    4.3 If the ICI Companies pay to the Purchaser Companies any amount under any
        of the  Agreements in respect of any Claim under such  Agreement and the
        Purchaser  Companies  are  thereafter  able to recover  any sum from any
        third  party  (including  any  insurer)  in respect of that  Claim,  the
        Purchaser  Companies  shall use all reasonable  endeavours to so recover
        any such sum and shall repay to the ICI  Companies so much of the amount
        paid by the ICI  Companies  as is  equal  to any  sum  recovered,  after
        allowing  for  the  reasonable  costs  and  expenses  of  the  Purchaser
        Companies reasonably incurred in connection therewith.

        Furthermore, if any liability on the part of the ICI Companies under any
        of the  Agreements  which  results  in a payment  being  made by the ICI
        Companies to the  Purchaser  Companies  gives rise to any  corresponding
        saving or rebate for the Purchaser  Companies  (including any tax saving
        or rebate) then the value of such corresponding  saving or rebate to the
        Purchaser  Companies  shall  be set  against  the  liability  of the ICI
        Companies in the particular instance.


      5 CONSIDERATION REDUCED BY CLAIMS

        Any payment by the ICI Companies paid to the Purchaser Companies (or for
        the Purchaser  Companies'  benefit) in respect of any Claim or Tax Claim
        shall be deemed to be a reduction in the consideration payable under the
        relevant Agreement in respect of the business,  assets or shares thereby
        sold.

      6 NO SET-OFF

        None of the Purchaser Companies shall be entitled to set off any amounts
        due to it by the  ICI  Companies  (whether  under  this  agreement,  the
        Agreements  or  otherwise)  against  the sums owing (or  claimed by such
        other party to be owing) under the terms of this agreement.

                        INTERCORPORATE SERVICES AGREEMENT

      This INTERCORPORATE SERVICES AGREEMENT (the "AGREEMENT"),  effective as of
January 1, 1998,  amends and  supersedes  that certain  Intercorporate  Services
Agreement effective as of January 1, 1997 by and between CONTRAN CORPORATION,  a
Delaware  corporation  ("CONTRAN"),  and  NL  INDUSTRIES,  INC.,  a  New  Jersey
corporation. ("RECIPIENT"),

      A.  Harold C.  Simmons,  an  employee  of Contran  and a director  and the

      C. The cost of engaging the advisory  services of someone  possessing  Mr.
Simmons'  expertise  and the cost of  maintaining  the  personnel  necessary  to
perform the functions  provided for by this  Agreement  would exceed the fee set
forth in SECTION 3 of this Agreement and the terms of this Agreement are no less
favorable to Recipient  than could  otherwise be obtained from a third party for
comparable services.

      D. Recipient desires to continue receiving the advisory services of Harold
C. Simmons and Contran is willing to continue to provide such services under the
terms of this Agreement.

                                    AGREEMENT

gross negligence on the part of such person.

      SECTION 8. FURTHER  ASSURANCES.  Each of the parties  will make,  execute,
acknowledge and deliver such other instruments and documents,  and take all such
other actions,  as the other party may reasonably  request and as may reasonably
be required in order to effectuate  the purposes of this  Agreement and to carry

terminated or discontinued Services.

      3. LIMITATION OF LIABILITY. In providing Services hereunder, NL shall have
a duty to act, and to cause its agents to act, in a reasonably  prudent  manner,
but  neither  NL nor any  officer,  director,  employee  or agent of NL shall be
liable to Tremont or its  subsidiaries  for any error of  judgment or mistake of
law or for any loss incurred by Tremont or its  subsidiaries  in connection with
the  matters to which  this  Agreement  relates,  except a loss  resulting  from
willful  misfeasance,  bad faith or gross  negligence  on the part of NL or from
NL's reckless disregard of obligations and duties under this Agreement.

      4.  INDEMNIFICATION  OF NL BY TREMONT.  Tremont  shall  indemnify and hold
harmless NL, its  subsidiaries  and their  respective  officers,  directors  and
employees  from and against any and all losses,  liabilities,  claims,  damages,
costs and expenses (including  reasonable  attorneys' fees and other expenses of
litigation) to which such party may become subject  arising out of the provision
by NL to Tremont and its subsidiaries of any of the Services, provided that such
indemnity  shall not protect any such party  against any liability to which such
person would otherwise by subject by reason of willful  misfeasance,  bad faith,
gross negligence or reckless disregard of obligations and duties hereunder.

      5. FURTHER ASSURANCE. Each of the parties will make, execute,  acknowledge

                        INTERCORPORATE SERVICES AGREEMENT



      This INTERCORPORATE SERVICES AGREEMENT (the "AGREEMENT"),  effective as of
January 1, 1998,  amends and  supersedes  that certain  Intercorporate  Services
Agreement  effective  as of January 1, 1997 between NL  INDUSTRIES,  INC., a New
Jersey corporation ("NL"), and COMPX INTERNATIONAL INC., a Delaware  corporation
("RECIPIENT").

                                    RECITALS

      A. NL provides  Recipient  certain  occupancy and related office  services
(the "OCCUPANCY AND RELATED OFFICE SERVICES"),  which services include,  without
limitation,  office space that  Recipient's  personnel  currently occupy at NL's
corporate offices at Two Greenspoint  Plaza, 16825 Northchase Drive, Suite 1200,
Houston, Texas and mail, telecommunication,  computer support, copying and other
reasonable office services related to such occupancy.

      B. The terms of this  Agreement  are no less  favorable to Recipient  than
could otherwise be obtained from a third party for comparable services.

      C.  Recipient  desires to continue  receiving  the  Occupancy  and Related
Office Services  presently provided by NL and affiliates of NL and NL is willing
to continue to provide such services under the terms of this Agreement.

                                    AGREEMENT

      For and in  consideration  of the  mutual  premises,  representations  and
covenants herein contained, the parties hereto mutually agree as follows:

      SECTION  1.  SERVICES  TO BE  PROVIDED.  NL  agrees to make  available  to
Recipient the following services (the "SERVICES") to be rendered by the internal
staff of NL and affiliates of NL:

            (a)   the Occupancy and Related Office Services; and

            (b) such other  services as may be  requested by Recipient or deemed
      necessary and proper from time to time.

      SECTION 2. MISCELLANEOUS  SERVICES. It is the intent of the parties hereto
that NL provide only the Services  requested  by  Recipient in  connection  with
routine administrative  functions related to the ongoing operations of Recipient
and not with  respect  to special  projects,  including  corporate  investments,
acquisitions and divestitures.  The parties hereto contemplate that the Services
rendered in  connection  with the conduct of  Recipient's  business will be on a
scale  compared to that existing on the effective date of this Agreement but not
for major corporate  acquisitions or  divestitures,  and that adjustments may be
required  to the terms of this  Agreement  in the event of such major  corporate
acquisitions,  divestitures or special projects. Recipient will continue to bear
all other costs required for outside  services,  and it is expressly  understood
that NL assumes no  liability  for any  expenses  or  services  other than those
stated in  SECTION 1. In  addition  to the fee paid to NL by  Recipient  for the
Services  provided  pursuant  to this  Agreement,  Recipient  will pay to NL the
