ITEM 2         ACQUISITION OR DISPOSITION OF ASSETS


               Effective October 17, 1997, LII Europe S.A.R.L (the "JV
Subsidiary"), a wholly owned subsidiary of LaRoche Industries Inc., a Delaware
corporation (the "Company") acquired a 50% interest in ChlorAlp S.A.S.
("ChlorAlp"), a joint venture company with Rhone-Poulenc Chimie S.A. ("RPC"),
a subsidiary of Rhone-Poulenc, S.A., for approximately U.S. $34.2 million.
Chloralp is a joint venture that owns and operates, among other things, a
chlorine, caustic soda and bleach manufacturing and distribution facility in
Pont-de-Claix, France.  RPC contributed the facility, which has 265,000 ton
per annum production capacity, as well as certain other related assets
(including ownership interests in brine extraction and transportation
facilities and a powerhouse) and liabilities, to ChlorAlp.  In connection with
such transactions, the JV Subsidiary and RPC entered into a Stock Purchase
Agreement, a Shareholders Agreement governing certain rights and obligations
between the shareholders, and a Put and Call Agreement providing for certain
rights of each party to require the other to buy or sell its respective
interest in ChlorAlp under certain circumstances.  Agreements relating to the
facility's power supply, the purchase and sale of the facility's output, and
other operating agreements were entered into on such date.  The purchase price
was negotiated among the parties based upon the fair market value of the
property and equipment, RPC's cost of the inventory, and the perceived value
of the power supply and other operating agreements.  ChlorAlp intends to
continue to use the facility to manufacture and distribute chlorine, caustic
soda and bleach.  The Company funded the purchase of such stock with funds
drawn from the term loan portion of its credit facility with The Chase
Manhattan Bank as agent.

None of the Company, any of its affiliates, or, to the knowledge of the
Company any director or officer of the Company or any associate of any such
director or officer, had any material relationship with Rhone-Poulenc, S.A. or
any of its affiliates prior to the formation of the joint venture.

                   AMENDMENT TO THE STOCK PURCHASE AGREEMENT



         This AMENDMENT (the "Amendment"), dated October 17, 1997, amends the
Stock Purchase Agreement by and among RHONE-POULENC CHIMIE S.A. ("Seller"), LII
Europe S.A.R.L. ("Buyer"), LAROCHE INDUSTRIES INC. ("Guarantor") and RHONE L
S.A.S. (now named ChlorAlp) ("Company"), in accordance with Section 11.2 of the

Agreement.


                              W I T N E S S E T H:


         WHEREAS, Seller contributed to the Company on September 1, 1997,
pursuant to the Transfer Agreement dated July 29, 1997, by means of a partial
asset contribution subject to the regime of article 817-1 of the French tax
code, a complete and autonomous branch of activity specializing in research,
design, manufacturing and marketing of chlorine, bleach soda, as well as brine
mining activity, made up of various assets and liabilities;

         WHEREAS, Seller, Buyer, Guarantor and Company have entered into the
Stock Purchase Agreement; and

         WHEREAS, Seller, Buyer, Guarantor and Company desire to amend the
Stock Purchase Agreement;

         NOW, THEREFORE, in consideration of the premises and agreements
contained herein, the parties hereto agree as follows:


1.       Amendment to Section 11.5 of the Stock Purchase Agreement.

         Section 11.5 of the Stock Purchase Agreement shall be amended by
adding the following clauses:

"(d)     In the event that the tax regime regarding registration duties shall
         be challenged by any Governmental Entity on the basis of the 
         provisions ofarticles 719 and 720 of the French tax code, imposing a
         tax reassessment on the Company or Buyer, Seller undertakes to
         indemnify the Company or Buyer, as the case may be, for the amount of
         registration duties effectively assessed, including penalties and late
         payment interest [as well as reasonable attorney fees].  The amount
<PAGE>   2
                                     -2-

         of the indemnification shall be reduced by the value of any tax
         benefit or tax savings realized or reasonably expected to be realized
         as a result of the tax reassessment and the payment of any attorney
         fees in connection therewith.


(e)      The indemnification under paragraph (d) above shall survive until
         December 31, 2007, corresponding to the tax authorities' statute of
         limitation with respect to registration duties in application of
         articles L. 180 and L.  186 of the French book of tax procedures.


(f)      The indemnification given by Seller under paragraph (d) above shall
         not apply if the tax reassessment arises out of the contribution or
         transfer of the constructions in process (" immobilisations en
         cours").


(g)      Guarantor, Buyer and the Company agree to cooperate with Seller if any
         Governmental Entity attempts such tax reassessment.  Guarantor, Buyer,
         the Company and Seller, prior to making any communication to any
         Governmental Entity, shall agree on the terms of any such
         communication.  Guarantor, Buyer or the Company shall not settle or
         compromise without the written consent of Seller, which consent shall
         not be unreasonably withheld or delayed."


2.       Confidentiality.

         Guarantor, Buyer, the Company and Seller undertake to maintain the
terms of this Amendment in confidence and not to disclose or communicate its
terms to any third party, except that they may communicate this Amendment to

instructed to keep confidential the terms of this Amendment.


3.       Counterparts.

         This Amendment may be executed in one or more counterparts, each of
which shall be considered one and the same instrument.


4.       Governing Law.

         This Amendment shall be governed and construed in accordance with
Section 11.4 of the Stock Purchase Agreement.

Purchase Agreement shall remain in full force and effect.

the guarantee signed on August 1st, 1997 by Guarantor and Buyer, the provisions

                   AMENDMENT TO THE STOCK PURCHASE AGREEMENT


                 This AMENDMENT (the "Amendment"), dated October 17, 1997,
amends the Stock Purchase Agreement by and among RHONE-POULENC CHIMIE S.A.
("Seller"), LII Europe S.A.R.L. ("Buyer"), LAROCHE INDUSTRIES INC.

them in the Stock Purchase Agreement.


                              W I T N E S S E T H:


         WHEREAS, Seller, Buyer, Guarantor and Company have entered into the
Stock Purchase Agreement; and

         WHEREAS, Seller, Buyer, Guarantor and Company desire to amend the
Stock Purchase Agreement;

         NOW, THEREFORE, in consideration of the premises and agreements
contained herein, the parties hereto agree as follows:


         1.      Article 1 shall be amended by deleting the existing text in
its entirety and substituting the following text:


                                  "ARTICLE 1"

                          PURCHASE AND SALE OF SHARES


         1.1     Sale of Shares.  Subject to the terms and conditions hereof,
Seller agrees to sell, assign and transfer to Buyer and Buyer agrees to
purchase from Seller, on the Closing Date, 1,513,620 of the Shares,
representing 50% of the Shares.

         1.2     Purchase Price and Payment.  (a)  The purchase price
("Purchase Price") for the Shares to be purchased hereunder shall be one
hundred twenty three million five hundred thirty two thousand eight hundred
seventy four French Francs (FF 123,532,874) (as calculated pursuant to Schedule
1.2) and shall be payable at Closing (as defined in Section 5.1).  The Purchase
Price has been determined by mutual agreement on the basis of the valuation of
the Division as set forth in the Transfer Agreement, as adjusted, less a
discount of fifteen percent (15%) to reflect the sale of less than 100% of the
Shares
<PAGE>   6
                                     -3-

         (b)     Payment of the Purchase Price under this Agreement shall be
made to Seller by Buyer by Bank of France wire transfer (virement Banque de
France) in immediately available funds to an account of Seller designated by it
for such purpose.

         (c)     The Transfer and the CEV Transfer shall give rise to Transfer
Date Adjustments between Seller and the Company or CEVCO, as the case may be,
in accordance with Section 1.3 below.  The Closing shall give rise to a Post-
Closing Adjustment between Seller and Buyer in accordance with Sections 1.4
below.

         1.3     Adjustments as at the Transfer Date Between Seller and the
Company and Between Seller and CEVCO.

         1.3.1   Base Statements.  (a)  Attached hereto as Schedule 1.3.1(a) is
a balance sheet of the Division which reflects, as of December 31, 1996
("Reference Date") but subject to mutually agreed adjustments, the values of
the respective line items and reference accounts which are set forth in the
Transfer Agreement ("Company Base Statement").  The Company Base Statement has

Seller's Accounting Principles. As used herein, the term "Base Statements"
means the Company Base Statement and the CEVCO Base Statement.

         1.3.2   Adjustment Assumptions.  (a)  The adjustments to be made under
this Section 1.3 shall be made only and exclusively in respect of: (i) the
working capital line items referred to under the heading Actif Circulant in
section 2.2 of the Transfer Agreement (exclusive of the cash portion thereof

<PAGE>   7

                                     - 4 -

hereafter).  These line items are set forth on Schedule 1.3.5.

         (b)     As used herein with reference to the Division or the CEV
Business, the term "Cash and Inventory" means the sum of cash and cash
equivalents (exclusive of the cash portion thereof used to pay the purchase
price under the CEVCO Stock Purchase Agreement), plus the value of inventory,
determined on the basis of Seller's Accounting Principles, where inventory
shall include only raw materials, work in process, consumable processing
supplies, specific spare parts, and finished goods.

         1.3.3   Transfer Date Statements.  As soon as practicable and, in any
event, not later than thirty (30) calendar days after the Closing Date, Seller
shall deliver to:

                 (a)      the Company and Buyer a statement reviewed by
         Seller's Auditor ("Company Transfer Date Statement "), setting forth
         Seller's determination of (i) the amount of the Company Cash and
         Inventory as of the Transfer Date; (ii) the amount of the Transferred
         Liabilities as of the Transfer Date; and (iii) the amount of any
         Transfer Date Adjustment Amount to be paid pursuant to Section 1.3.5
         hereunder; and

                 (b)      CEVCO and Buyer a statement reviewed by Seller's
         Auditor (the "CEVCO Transfer Date Statement"), setting forth Seller's
         determination of (i) the amount of CEVCO Cash and Inventory as of the
         Transfer Date; (ii) the amount of the CEV Transferred Liabilities as
         of the Transfer Date; and (iii) the amount of any Transfer Date
         Adjustment Amount to be paid pursuant to Section 1.3.5 hereunder.

The Company Transfer Date Statement and the CEVCO Transfer Date Statement (each
a "Transfer Date Statement") shall be prepared on a basis consistent with the
Base Statements in accordance with Seller's Accounting Principles. Buyer's
Auditor, on behalf of Buyer, shall have access to all workpapers prepared by
Seller's Auditor and to accounting documents of Seller to the extent relating
exclusively to the Division in connection with its review of the Transfer Date
Statements.  Seller's and Buyer's Auditors shall limit their review to the line
items referred to on Schedule 1.3.5.

         1.3.4   Determination of any Transfer Date Adjustment Amounts.  The
payment of the Transfer Date Adjustments between Seller and the Company and/or
between Seller and CEVCO as the case may be and the amount thereof, if any,
shall be determined as follows ("Transfer Date Adjustment Amounts"):

                 (i)        If (A) the aggregate value of the Company Cash and
         Inventory as shown on the Company Final Transfer

         Company Final Transfer Date Statement exceeds (B) the aggregate value
         of the Company Cash and Inventory as shown on the Company Base
         Statement less the Transferred Liabilities as shown on the Company
         Base Statement, a Transfer Date Adjustment Amount equal to the amount
         of such excess shall be due and payable by the Company to Seller in
         accordance with section 4.2 of the Transfer Agreement.  

                  (ii)    If (A) the aggregate value of the Company Cash and 
         Inventory as shown on the Company Final Transfer Date Statement less
         the Transferred Liabilities as shown on the Company Final Transfer
         Date Statement is less than (B) the aggregate value of the Company
         Cash and Inventory as shown on the Company Base Statement less the
         Transferred Liabilities as shown on the Company Base Statement, a
         Transfer Date Adjustment Amount equal to the amount of such difference
         shall be due by Seller to the Company in accordance with section 4.2
         of the Transfer Agreement.  

                  (iii)   If (A) the aggregate value of the CEVCO Cash and 
         Inventory as shown on the CEVCO Final Transfer Date Statement less the
         CEV Transferred Liabilities as shown on the CEVCO Final Transfer Date
         Statement exceeds (B) the aggregate value of the CEVCO Cash and
         Inventory as shown on the CEVCO Base Statement less the CEV
         Transferred Liabilities as shown on the CEVCO Base Statement, a
         Transfer Date Adjustment Amount equal to the amount of such excess
         shall be due and payable by CEVCO to Seller in accordance with Section
         4.2 of the CEV Transfer Agreement.  

                  (iv)    If (A) the aggregate value of the CEVCO Cash and 
         Inventory as shown on the CEVCO Final Transfer Date Statement less the
         CEV Transferred Liabilities as shown on the CEVCO Final Transfer Date
         Statement is less than (B) the aggregate value of the CEVCO Cash and
         Inventory as shown on the CEVCO Base Statement less the CEV
         Transferred Liabilities as shown on the CEVCO Base Statement, a
         Transfer Date Adjustment Amount equal to the amount of such difference
         shall be due by Seller to CEVCO in accordance with Section 4.2 of the
         CEV Transfer Agreement.

                 (v)      For the avoidance of doubt, Schedule 1.3.5
         hereto sets forth hypothetical determinations of the Transfer Date
         Adjustment Amounts.

Seller shall deliver to Buyer a statement reviewed by Seller's Auditor and
prepared on a consolidated basis ("Closing Statement"), setting forth Seller's

Loss at the Closing Date" shall be determined on a consolidated basis after tax
comprising the Company and CEVCO (to the extent of 60% of CEVCO's profit or
loss) for the period from the Transfer Date to the Closing Date (or the
month-end immediately prior to the Closing Date if the Closing Date is not the
first business day of the month, in which event interest on the Purchase Price
shall be payable from the beginning of the month to the Closing Date at a rate
of PIBOR for one month deposits plus 100 basis points) and shall be calculated
and determined on a basis consistent with Seller's Accounting Principles
(provided that depreciation shall be calculated in accordance with historical
asset values and depreciation schedules without giving effect to the write-up
of assets effected pursuant to the Transfer).  Buyer's Auditor, on behalf of
Buyer, shall have access to all workpapers prepared by Seller's Auditor and to
accounting documents of Seller to the extent relating exclusively to the
Division in connection with its review of the Closing Statement.

         1.4.2         Determination of any Post-Closing Adjustment Amounts.
The payment of the post-closing adjustments between Seller and Buyer and the
amount thereof, if any, shall be determined as follows ("Post-Closing
Adjustment Amounts"):

                 (i)   If the Net Profit or Loss at the Closing Date is 
         positive, a Post Closing Adjustment Amount equal to fifty percent
         (50%) of the amount of such profit shall be due and payable by Buyer
         to Seller.

                 (ii)  If the Net Profit or Loss at the Closing Date is 
         negative, a Post-Closing Adjustment Amount equal to fifty percent
         (50%) of the amount of such loss shall be due by Seller to Buyer.

         1.5     Adjustment Procedures.

         1.5.1         Disputes Regarding Statements.  (a)  Buyer shall have 
twenty (20) business days after the delivery to Buyer of the Transfer Date
Statements or the Closing Statement, as the case may be (collectively
"Statements") in which to review the Statements and the workpapers referred to
above related thereto.  Unless Buyer notifies Seller in writing within such
twenty-day periods of any objection to the Statements, specifying in reasonable
detail the items and amounts subject to such objection ("Disputed Items"), the
Statements (including the Adjustment

<PAGE>   10

                                     - 7 -

Amounts, if any, shown thereon) shall be conclusive and binding on Buyer and
Seller. If within such twenty-day period, Buyer notifies Seller in writing of
any such objection, then Buyer and Seller shall use reasonable efforts for
fifteen (15) business days after the expiration of such initial twenty-day
period to resolve in good faith their differences and agree upon any
adjustments to the Statements (including any Adjustment Amounts shown thereon).
Any Disputed Items which are not resolved by the mutual agreement of Buyer and
Seller within such fifteen-day period shall be submitted for resolution to the
Paris, France office of Price Waterhouse or such other internationally
recognized accounting firm as is mutually acceptable to Buyer and Seller and
independent of each of them and failing such mutual agreement an
internationally recognized accounting firm independent of each of them
designated by the President of the Commercial Court of Paris statuant en refere
("Independent Accounting Firm"). Seller and Buyer shall instruct the
Independent Accounting Firm to limit its examination to the unresolved Disputed
Items, to resolve any unresolved Disputed Items affecting the Statements in
such manner as to preserve the conformity of the Statements with the
requirements described in Section 1.3.3 hereof and to use its best efforts to
make its determination thereon within twenty (20) business days after its
engagement hereunder.  The Independent Accounting Firm shall hear both parties
and their advisers and shall in all respects enforce the "principe du
contradictoire".  The resolution of any such previously unresolved Disputed
Items by such Independent Accounting Firm shall be made in a written notice
delivered to Buyer and Seller as promptly as practicable (which written notice
shall set forth the amount of any Adjustment Amounts as finally determined) and
shall be final, conclusive and binding upon Seller, Buyer, the Company and
CEVCO. Seller and Buyer each shall pay one-half of the fees and expenses
charged by the Independent Accounting Firm.

         (b)     Each Statement to which Buyer does not object as provided in
Section 1.3.7(a) hereof, or to which Seller and Buyer agree, or as otherwise
conclusively determined pursuant to Section 1.3.7(a) hereof (any such final
form of Statement being referred to herein as the respective "Final Statement")
shall be used in determining the Adjustment Amounts and any further
adjustments.

         1.5.2   Payment.  Within eight (8) business days after the lapse of
the twenty (20) business day period referred to in the first sentence of 
Section 1.5.1, the estimated amount of any Adjustment Amounts excluding any
amount of any Disputed Items, shall be paid by bank wire transfer of the
required amount (in immediately available funds).  The remaining unpaid amount
of any
<PAGE>   11

                                     - 8 -

Adjustment Amounts, if any, shall be paid within eight (8) business days of the
resolution of all Disputed Items and determination of each Final Statement, by
bank wire transfer of the required amount (in immediately available funds).
The Adjustment Amounts shall be increased by interest at a rate of seven
percent (7%) per annum accruing from the expiration of the above-referenced
eight day period to the date of payment of such amounts.  Such payment of late
interest shall not be deemed to constitute an agreement or waiver by any of the
parties hereto to delay the payment of any Adjustment Amounts.

         2.      Section 2.1.8 shall be amended by the addition of the
following paragraph 2.1.8(d):

         "Seller does not, has not, nor has ever, owned any real property (or
rights with respect thereto) at or relating to the Saint Fons Facility (as
defined at Section 2.1.11(c) below)."

         3.      Section 2.1.11 shall be amended by the addition of the
following paragraph 2.1.11(c):

understanding, arrangement or undertaking (whether written or oral) between
such parties with respect to the bleach production facilities located at Saint
Fons ("Saint Fons Facility"), and, other than the provisions of the Atochem
Contract, there exists no obligation of Seller or Company to indemnify Seller
or any other person with respect to the Saint Fons Facility."

         4.      Section 3.1.2 shall be amended by the addition of the

facilities of ChlorAlp at Hauterives, the St. Fons Facility and the CEVCO
Facility, which capital expenditures shall, in each case, be made by Seller at
the times and in accordance with established Seller procedures and in the
Ordinary Course of Business, said capital expenditures being adjusted for in
accordance with Schedule 1.2."

         5.       Section 3.1.6 shall be amended by deleting the existing

         "With respect to easements and servitudes that burden the brine
pipeline between Hauterives and Pont de Claix and/or the transferred portion of

consent of the landowner, Seller shall exert its Best Efforts to obtain such
required consents in due course after Closing and shall hold harmless the
Company in the event the Company shall be held liable financially for breach of

Date and for so long as the other parties under these agreements shall not have
entered into contracts with the Company providing for terms and conditions
similar to those provided by these agreements but limited in scope to the
Division, Seller shall (i) exert its Best Efforts to cause such other parties
to continue supplying the services to the Company and/or CEVCO, as the case may
be, in a manner consistent with past practice; (ii) provide alternative or
substitute arrangements effective as of the Closing Date providing the benefit
of such agreements to the Company in a manner reasonably satisfactory to Buyer;

Efforts to cooperate with Buyer to obtain such additional information and to
make such additional inquiries and investigations with respect to the Saint
Fons Facility and the operations thereat as Buyer shall have reasonably

                           PURCHASE AND SALE OF SHARES


     1.1 Sale of Shares. Subject to the terms and conditions hereof, Seller
agrees to sell, assign and transfer to Buyer and Buyer agrees to purchase from
Seller, on the Closing Date, 1,512,370 of the Shares, representing 50% of the

for the Shares to be purchased hereunder shall be one hundred twenty eight
million five hundred fifty one thousand four hundred fifty French Francs (FF
128,551,450) (as calculated pursuant to Schedule 1.2) and shall be payable at
Closing (as defined in Section 5.1). The Purchase Price has been determined by
mutual agreement on the basis of the valuation of the Division as set forth in
the Transfer Agreement, less a discount of fifteen percent (15%) to reflect the
sale of less than 100% of the Shares and the shared control of the Company.

     (B) Payment of the Purchase Price under this Agreement shall be made to

immediately available funds to an account of Seller designated by it for such
purpose.

Seller; instead, Buyer and Seller shall cause the Company and Seller, or CEVCO 
and Seller, respectively, to make the adjustments described in Section 1.3 in
connection with the Transfer and the CEV Transfer. Similarly, there shall be no
adjustment of the purchase price between Seller and the Company payable under
the CEVCO Stock Purchase Agreement, because of the adjustments to be made
between Seller and CEVCO which are described in Section 1.3 in connection with
the CEV Transfer.

CEVCO.

     1.3.1         Base Statements. (a) Attached hereto as Schedule 1.3.1(a) is 
a balance sheet of the Division which
<PAGE>   28
                                      -5-

reflects, as of December 31, 1996 ("Reference Date") but subject to mutually
agreed adjustments, the values of the respective line items and reference
accounts which are set forth in the Transfer Agreement ("Company Base
Statement"). The Company Base Statement has been prepared in accordance with
Seller's Accounting Principles (as defined in Section 2.1.4 hereafter).

     (b) Attached hereto as Schedule 1.3.1(b) is a balance sheet of the CEV
business which reflects, as of the Reference Date but subject to mutually agreed
adjustments, the values of the respective line items and reference accounts
which are set forth in the CEV Transfer Agreement ("CEVCO Base Statement"). The
CEVCO Base Statement has been prepared in accordance with Seller's Accounting
Principles. As used herein, the term "Base Statements" means the Company Base
Statement and the CEVCO Base Statement.

     1.3.2        Adjustment Assumptions. (a) The adjustments to be made under 
this Section 1.3 shall be made only and exclusively in respect of: (i) the
working capital line items referred to under the heading Actif Circulant in
section 2.2 of the Transfer Agreement (exclusive of the cash portion thereof
used by the Company to pay the purchase price under the CEVCO Stock Purchase
Agreement) ("Company Cash and Inventory"); (ii) the liabilities referred to in
section 2.3 of the Transfer Agreement (i.e., the Transferred Liabilities as
defined in Section 4.1.3 hereafter); (iii) the working capital line items
referred to under the heading Actif Circulant in Section 2.1 of the CEV Transfer
Agreement ("CEVCO Cash and Inventory"); and (iv) the liabilities referred to in

as defined in Section 4.1.4 hereafter). These line items are set forth on
Schedule 1.3.5.

     (b) As used herein with reference to the Division or the CEV Business,
the term "Cash and Inventory" means the sum of cash and cash equivalents 
(exclusive of the cash portion thereof used to pay the purchase price under the
CEVCO Stock Purchase Agreement), plus the value of inventory, determined on the
basis of Seller's Accounting Principles, where inventory shall include only raw

      1.3.3       Closing Statements.  As soon as practicable and, in any event,
not later than thirty (30) calendar days after the Closing, Seller shall deliver
to:

           (a)    the Company and Buyer a statement reviewed by Seller's Auditor
      ("Company Closing Statement"), setting forth Seller's determination of (i)
      the amount of the Company Cash and Inventory as of the Closing Date; (ii)
      the amount of the Transferred Liabilities as of the Closing Date; and
      (iii) the amount of any Post-Closing Adjustment Amount to be paid pursuant
      to Section 1.3.5 hereunder; and

           (b)    CEVCO and Buyer a statement reviewed by Seller's Auditor (the
      "CEVCO Closing Statement"), setting forth Seller's determination of (i)
      the amount of CEVCO Cash and Inventory as of the Closing Date; (ii) the
      amount of the CEV Transferred Liabilities as of the Closing Date; and
      (iii) the amount of any Post-Closing Adjustment Amount to be paid pursuant
      to Section 1.3.5 hereunder.

The Company Closing Statement and the CEVCO Closing Statement (each a "Closing
Statement") shall be prepared on a basis consistent with the Base Statements in
accordance with Seller's Accounting Principles. Buyer's Auditor, on behalf of
Buyer, shall have access to all workpapers prepared by Seller's Auditor and to
accounting documents of Seller to the extent relating exclusively to the
Division in connection with its review of the Closing Statements. Seller's and
Buyer's Auditors shall limit their review to the line items referred to on
Schedule 1.3.5.

     1.3.4        Disputes Regarding Closing Statements. (a) Buyer shall have 
twenty (20) business days after the delivery to Buyer of the Closing Statements
in which to review the Closing Statements and the workpapers referred to above
related thereto. Unless Buyer notifies Seller in writing within such twenty-day
period of any objection to the Closing Statements, specifying in reasonable
detail the items and amounts subject to such objection ("Disputed Items"), the
Closing Statements (including the Post-Closing Adjustment Amounts, if any, shown
thereon) shall be conclusive and binding on Buyer and Seller. 
<PAGE>   30
                                      -7-

If within such twenty-day period, Buyer notifies Seller in writing of any such
objection, then Buyer and Seller shall use reasonable efforts for fifteen (15)
business days after the xpiration of such initial twenty-day period to resolve 
in good faith their differences and agree upon any adjustments to the Closing
Statements (including any Post-Closing Adjustment Amounts shown thereon). Any
Disputed Items which are not resolved by the mutual agreement of Buyer and
Seller within such fifteen-day period shall be submitted for resolution to the
Paris, France office of Price Waterhouse or such other internationally
recognized accounting firm as is mutually acceptable to Buyer and Seller and
independent of each of them and failing such mutual agreement an internationally
recognized accounting firm independent of each of them designated by the
President of the Commercial Court of Paris statuant en refere ("Independent
Accounting Firm"). Seller and Buyer shall instruct the Independent Accounting
Firm to limit its examination to the unresolved Disputed Items, to resolve any
unresolved Disputed Items affecting the Closing Statements in such manner as to
preserve the conformity of the Closing Statements with the requirements
described in Section 1.3.3 hereof and to use its best efforts to make its
determination thereon within twenty (20) business days after its engagement
hereunder. The Independent Accounting Firm shall hear both parties and their
advisers and shall in all respects enforce the "principe du contradictoire". The
resolution of any such previously unresolved Disputed Items by such Independent
Accounting Firm shall be made in a written notice delivered to Buyer and Seller
as promptly as practicable (which written notice shall set forth the amount of
any Post-Closing Adjustment Amounts as finally determined) and shall be final,
conclusive and binding upon Seller, Buyer, the Company and CEVCO. Seller and
Buyer each shall pay one-half of the fees and expenses charged by the
Independent Accounting Firm.

     (b) Each Closing Statement to which Buyer does not object as provided in
Section 1.3.4(a) hereof, or to which Seller and Buyer agree, or as otherwise
conclusively determined pursuant to Section 1.3.4(a) hereof (any such final form
of Closing Statement being referred to herein as the "Company Final Closing
Statement" for the Company and the "CEVCO Final Closing Statement" for CEVCO,
and collectively the "Final Closing Statements") shall be used in determining
the Post-Closing
<PAGE>   31
                                      -8-

Adjustment Amounts and any further adjustments, which will be promptly paid by
Seller to the Company, or by the Company to Seller, and/or by Seller to CEVCO,
or by CEVCO to Seller, as the case may be.

     1.3.5        Determination of any Post-Closing Adjustment Amounts. The 
payment of the post-closing adjustments between Seller and the Company and/or
between Seller and CEVCO as the case may be and the amount thereof, if any,
shall be determined as follows ("Post-Closing Adjustment Amounts"):

           (i)             If (A) the aggregate value of the Company Cash and 
         Inventory as shown on the Company Final Closing Statement less the
         Transferred Liabilities as shown on the Company Final Closing Statement
         exceeds (B) the aggregate value of the Company Cash and Inventory as
         shown on the Company Base Statement less the Transferred Liabilities as
         shown on the Company Base Statement, a Post Closing Adjustment Amount
         equal to the amount of such excess shall be due and payable by the
         Company to Seller in accordance with section 4.2 of the Transfer
         Agreement.

           (ii)            If (A) the aggregate value of the Company Cash and 
         Inventory as shown on the Company Final Closing Statement less the
         Transferred Liabilities as shown on the Company Final Closing Statement
         is less than (B) the aggregate value of the Company Cash and Inventory
         as shown on the Company Base Statement less the Transferred Liabilities
         as shown on the Company Base Statement, a Post-Closing Adjustment
         Amount equal to the amount of such difference shall be due by Seller to
         the Company in accordance with section 4.2 of the Transfer Agreement.

           (iii)           If (A) the aggregate value of the CEVCO Cash and
         Inventory as shown on the CEVCO Final Closing Statement less the CEV
         Transferred Liabilities as shown on the CEVCO Final Closing Statement
         exceeds (B) the aggregate value of the CEVCO Cash and Inventory as
         shown on the CEVCO Base Statement less the CEV Transferred Liabilities
         as shown on the CEVCO Base Statement, a Post Closing Adjustment Amount
         equal to the amount of such excess shall be due and payable by CEVCO to
         Seller in accordance with Section 4.2 of the CEV Transfer Agreement.
<PAGE>   32

                                      -9-

           (iv)            If (A) the aggregate value of the CEVCO Cash and 
         Inventory as shown on the CEVCO Final Closing Statement less the CEV
         Transferred Liabilities as shown on the CEVCO Final Closing Statement
         is less than (B) the aggregate value of the CEVCO Cash and Inventory as
         shown on the CEVCO Base Statement less the CEV Transferred Liabilities
         as shown on the CEVCO Base Statement, a Post-Closing Adjustment Amount
         equal to the amount of such difference shall be due by Seller to CEVCO

           (v)             For the avoidance of doubt, Schedule 1.3.5 hereto 
         sets forth hypothetical determinations of the Post-Closing Adjustment
         Amounts.

         1.3.6      Payment. Within eight (8) business days after the lapse of 
the  twenty (20) business day period referred to in the first sentence of
Section 1.3.4, the estimated amount of any Post-Closing Adjustment Amounts
excluding any amount of any Disputed Items, shall be paid respectively to or by
Seller by or to the Company and/or CEVCO, as the case may be, by bank wire
transfer of the required amount (in immediately available funds). The remaining
unpaid amount of any Post-Closing Adjustment Amounts, if any, shall be paid to
or by Seller, as the case may be, within eight (8) business days of the
resolution of all Disputed Items and determination of each Final Closing
Statement, by bank wire transfer of the required amount (in immediately

interest at a rate of seven percent (7%) per annum accruing from the expiration
of the above-referenced eight day period to the date of payment of such
amounts. Such payment of late interest shall not be deemed to constitute an
agreement or waiver by any of the parties hereto to delay the payment of any

         Seller contained in this Agreement;

                  (c) any claim by any Person for brokerage or finder's fees or
         commissions or similar payments based upon any agreement or
         understanding alleged to have been made by any such Person with Seller
         (or any Person acting on its behalf) in connection with the
         transactions contemplated hereby;

                  (d) those items specifically listed on Schedule 6.1; or

                  (e) any claim by (or by another Person on behalf of) any
         current or former employee of the Division or the CEV business for
         death, personal injury or related loss, expense, damage, liability or
         disability, incurred as the result of exposure to asbestos or
         asbestos-containing material during the course of such employment in
         so far as the employee becomes aware of the injury within twenty (20)
         years of Closing.

         6.2 Indemnification by Buyer. Subject to the terms and conditions of
this Agreement (and, with respect to Environmental Indemnifiable Losses, as
defined in Section 7.3 below, subject to Article 7 hereof), Buyer agrees to
indemnify and hold Seller harmless from and against any and all Indemnifiable
Losses suffered or incurred by Seller and arising or resulting from:

                  (a) any breach of any representation or warranty of Buyer or
         Guarantor contained in Section 2.2 or 2.3 hereof, except to the extent
         any such breach is waived by Seller pursuant to Section 4.2 hereof;

                  (b) any breach by Buyer or Guarantor of any covenant or
         obligation of Buyer or Guarantor contained in this Agreement; or

                  (c) any claim by any Person for brokerage or finder's fees or
         commissions or similar payments based upon any agreement or
         understanding alleged to have been 
<PAGE>   71
                                     -48-

         made by any such Person with Buyer or Guarantor (or any Person acting
         on behalf of Buyer or Guarantor) in connection with the transactions
         contemplated hereby.

         6.3 When Payable. Indemnification under this Article 6 and Article 7
hereof shall be payable with respect to any claim concerning an Indemnifiable
Loss or an Environmental Indemnifiable Loss upon the occurrence of the earliest
of (a) any payment required to be made to any tax or other administrative
authority with respect to any claim from such authority, (b) the resolution of
such claim by mutual agreement between Seller and Buyer and/or the Company
and/or CEVCO, as the case may be, (c) the issuance of a jugement executoire par
provision provided however that if a final judgment subsequently reverses in
whole or in part the jugement executoire par provision, the Indemnified Party
shall promptly reimburse to the Indemnifying Party as and when cash is actually
received by the Indemnified Party from any claimant an amount equal to the
amount received by such Indemnified Party as a result of this final judgment up
to the amount paid by the Indemnifying Party as a result of such claim, (d) the
issuance of a final judgment, award, order or other ruling (which is not
subject to appeal or with respect to which the time for appeal has elapsed) by
a court or arbitral tribunal having jurisdiction over the parties and the
subject matter of such claim or to which such claim was submitted for
resolution by joint agreement between Seller and Buyer and/or the Company
and/or CEVCO, as the case may be, or (e) the final settlement of such claim
with a third party pursuant to mutual authorization by Seller and Buyer.

         6.4 Limitations on Indemnification. (a) Neither (i) the aggregate
indemnification obligations of Seller under Section 6.1 above, nor (ii) the
aggregate indemnification obligations of Buyer under Section 6.2 above, shall
exceed fifty percent (50%) of the Total Enterprise Value.

         (b) Notwithstanding any other provision of this Agreement: (i) no
claim in respect of any individual event or occurrence shall be deemed to give
rise to an Indemnifiable Loss (other than an Environmental Indemnifiable Loss,
as to which Section 7.8 shall apply) unless and until the liability, loss or
damage claimed exceeds fifty thousand French Francs (FF 

<PAGE>   72

                                     -49-

50,000), it being understood that individual events or occurrences of a
substantially similar nature that arise out of a single or directly related
origins, facts or circumstances shall be aggregated for purposes hereof as a
single Indemnifiable Loss; and (ii) neither Buyer (or the Company or CEVCO, as
the case may be) nor Seller shall be entitled to make a claim under Section 6.1
or Section 6.2 respectively unless and until the aggregate amount of claims for
Indemnifiable Losses (other than an Environmental Indemnifiable Loss, as to
which Section 7.8 shall apply)) under clause (i) above exceeds three million
French Francs (FF 3,000,000), in which event (subject to clause (i) above) such
party may assert its right to indemnification hereunder only to the extent of
the excess provided however, that breaches of Seller's covenants set forth at
Sections 3.1.5 and 3.1.6 shall not be subject to the limitations set forth at
paragraph (a) or clauses (b)(i) or (ii) above and provided further that for
purposes of paragraphs (b)(i) and (b)(ii) above and Section 7.8(a) below
Indemnifiable Losses and Environmental Losses shall be calculated without
regard to any associated insurance recovery.

         (c) Any limitations on Seller's indemnification obligations set forth
in paragraphs (a) and (b) above or in Section 6.6 below shall not be deemed to
limit or qualify Seller's obligation to transfer the full amount of the
Transferred Assets and the CEV Transferred Assets pursuant to the Transfer
Agreement and the CEV Transfer Agreement respectively, and in the event of
breach of Seller's obligations pursuant to such agreements and to Section
2.1.1(b)(iii) and Section 2.1.1(c)(iii) hereof, Seller shall be under the
obligation of specific performance to transfer and convey to the Company or
CEVCO, as the case may be, such assets as should have been comprised within the
Transferred Assets or the CEV Transferred Assets, as the case may be.

         6.5 Procedures Relating to Indemnification of Third Party Claims. (a)
A party ("Indemnified Party") shall use its Best Efforts to notify the party
obligated to provide indemnification under this Agreement ("Indemnifying
Party") of any claim for any indemnification provided for under this Agreement
(including claims for Environmental Indemnifiable Losses) in respect of,
arising out of or involving a claim or demand made by any person against the
Indemnified Party ("Third 

<PAGE>   73
                                     -50-

Party Claim"), in writing, in reasonable detail and promptly, and in any event
within thirty (30) business days of the date the Indemnified Party shall have
knowledge of the Third Party Claim. Thereafter, the Indemnified Party shall
deliver to the Indemnifying Party, within ten (10) business days after the
Indemnified Party's receipt thereof, copies of all notices and documents
(including court papers) received by the Indemnified Party relating to the
Third Party Claim. The failure of an Indemnified Party so to notify an
Indemnifying Party or to deliver such copies shall not disqualify such
Indemnified Party from receiving indemnification from such Indemnifying Party
and shall not constitute a breach of this Agreement unless and to the extent
that such failure to notify materially and adversely affects the ability of the
Indemnifying Party to defend against any such Third Party Claim.

         (b) If a Third Party Claim is made against an Indemnified Party, the
Indemnifying Party shall be entitled to participate in the defense thereof and,
if it so chooses and acknowledges its obligation to indemnify the Indemnified
Party therefor, to assume, at its own expense, the defense thereof with counsel
selected by the Indemnifying Party; provided, however, that such counsel is not
reasonably objected to by the Indemnified Party. Should the Indemnifying Party
so elect to assume the defense of a Third Party Claim, the Indemnifying Party
shall not be liable to the Indemnified Party for legal expenses subsequently
incurred by the Indemnified Party in connection with the defense thereof. If
the Indemnifying Party assumes such defense, the Indemnified Party shall have
the right to participate in the defense thereof and to employ counsel, at its
own expense, separate from the counsel employed by the Indemnifying Party, it
being understood that the Indemnifying Party shall be liable for the fees and
expenses of counsel employed by the Indemnified Party for any period during
which the Indemnifying Party has failed to assume the defense thereof (other
than during the period prior to the time the Indemnified Party shall have given
notice of the Third Party Claim as provided above).

         (c) If the Indemnifying Party so elects to assume the defense of any
Third Party Claim, the Indemnified Party shall cooperate with the Indemnifying
Party in the defense or 

<PAGE>   74
                                     -51-

prosecution thereof. Such cooperation shall include (upon the Indemnifying
Party's request) the retention and the provision to the Indemnifying Party of
records and information to the extent practicable which are reasonably relevant
to such Third Party Claim, and making employees available on a mutually
convenient basis to provide additional information and explanation of any
material provided hereunder. Whether or not the Indemnifying Party shall have
assumed the defense of a Third Party Claim, the Indemnified Party shall not
admit any liability with respect to, or settle, compromise or discharge, such
Third Party Claim without the Indemnifying Party's prior written consent (which
consent shall not be unreasonably withheld). If the Indemnifying Party shall
have assumed the defense of a Third Party Claim, the Indemnified Party shall
agree to any settlement, compromise or discharge of a Third Party Claim which
the Indemnifying Party may recommend and which by its terms obligates the
Indemnifying Party to pay the full amount of the liability in connection with
such Third Party Claim, which releases the Indemnified Party completely in
connection with such Third Party Claim and which would not otherwise adversely
affect the Indemnified Party.

         (d) Should the Indemnifying Party elect not to assume the defense of
any Third Party Claim, it shall cooperate at its cost with the Indemnified
Party in the defense or prosecution thereof and shall supply the Indemnified
Party with all applicable information, records or documents it may have to
ensure the best defense of the Indemnified Party.

         6.6 Survival of Indemnification. The right of either party to make a
claim for any Indemnifiable Loss under Section 6.1(a) or 6.2(a) shall survive
the Closing Date until the second anniversary of the Closing Date and any such
claim once made within such period shall survive and be indemnifiable in
accordance with the terms hereof, except that (i) claims for breach of Section
2.1.23 shall survive for nine (9) months after the Closing Date; (ii) claims
for Environmental Indemnifiable Losses shall be governed by Section 7.9 hereof;
(iii) claims for breach of Sections 2.1.3(a),(b) and (c) and Section 2.1.19
shall survive for the applicable statute of limitation period plus sixty (60)
days and (iv) claims for breaches of Sections 2.1.3(d) and (e) shall survive
the Closing Date until the tenth anniversary of the Closing Date and (v) 

<PAGE>   75
                                     -52-

claims with respect to the matters identified in Schedule 6.1 shall survive for
the respective periods set forth therein.

         6.7 Miscellaneous Provisions. (a) The amount of any indemnity payable
hereunder on account of an Indemnifiable Loss or an Environmental Indemnifiable
Loss shall (subject to the second proviso at Section 6.4(b)) be reduced by any
insurance proceeds received by the Indemnified Party with respect thereto, and
further reduced by the value of any net tax benefit or tax savings realized or
reasonably determined to be realizable by the Indemnified Party as a result of
or related to the foregoing (including without limitation a tax deduction or
loss, basis adjustment and/or shifting of income, deductions, gains, loss
and/or credits), and increased by any tax incurred or reasonably expected to be
incurred by the Indemnified Party as a result of or related to the foregoing
(including without limitation any tax related to the inclusion, if required by
law, in gross income of insurance proceeds or a payment pursuant hereto) so
that the net indemnity received after tax corresponds to the Indemnifiable Loss
or Environmental Indemnifiable Loss after taxes. For the calculation of the
Indemnifiable Loss or Environmental Indemnifiable Loss, tax savings and tax
costs will be calculated so that the savings and costs will be optimized in an
equitable fashion.

         (b) Any indemnity payment by Seller to Buyer, the Company and/or CEVCO
on account of an Indemnifiable Loss or an Environmental Indemnifiable Loss
shall be understood to constitute damages and not a reduction in the Purchase
Price. Such payment by Seller shall be made to the persons (as between the
Company, CEVCO and/or Buyer) that shall have actually suffered the
Indemnifiable Loss or the Environmental Indemnifiable Loss and to the extent
made to the Company or CEVCO, the Company or CEVCO shall be third party
beneficiaries of Buyer's rights and remedies in respect of the Indemnifiable
Loss or the Environmental Indemnifiable Loss (by way of example, in respect of
breaches of representations, warranties or covenants with regard to the
Division, the CEV business and/or the Company's business or CEVCO's business,
the Indemnifiable Loss or Environmental Indemnifiable Loss shall be paid to the
Company and/or CEVCO, as the case may be (and, to the extent Seller shall fail
to make such payment Buyer shall 

<PAGE>   76
                                     -53-

have a direct right of action against Seller), but any breach of
representations, warranties or covenants with regard to title to Shares
constitutes an Indemnifiable Loss directly and actually suffered by Buyer and
therefore shall be paid directly to Buyer), provided that, upon Buyer's
request, the payment of an Indemnifiable Loss or an Environmental Indemnifiable
Loss by Seller with respect to a Third Party Claim may be made directly to the
third party claimant.


                                   ARTICLE 7

                         ENVIRONMENTAL INDEMNIFICATION


         7.1 Environmental Indemnification by Seller. Subject to the terms and
conditions of this Agreement, Seller agrees to indemnify and hold (subject to
Section 6.7(b) hereof) Buyer and Company and/or CEVCO and their respective
officers, directors, employees, agents, successors and assigns harmless from
and against any and all Environmental Indemnifiable Losses (as defined at
Section 7.3 below) suffered or incurred by Buyer or Company and/or CEVCO
resulting from (a) any breach of representation or warranty of Seller contained
in Section 2.1.17 hereof, or (b) any Remedial Action (as defined at Section 7.3
below) for which responsibility is to be borne by Seller in accordance with
Section 7.5 hereof.

         7.2 Environmental Indemnification by Buyer. Subject to the terms and
conditions of this Agreement, Buyer agrees to indemnify and hold (subject to
Section 6.7(b) hereof) Seller and Company and/or CEVCO and their respective
officers, directors, employees, agents, successors and assigns harmless from
and against any and all Environmental Indemnifiable Losses suffered or incurred
by Seller or Company and/or CEVCO resulting from any Remedial Action for which
responsibility is to be borne by Buyer in accordance with Section 7.5 hereof.

         7.3 Environmental Indemnifiable Losses. "Environmental Indemnifiable
Losses" means any and all damages, costs, claims, losses, liabilities,
penalties, fines, judgments and expenses (including reasonable legal,
consulting and engineering fees and expenses) imposed by, under or pursuant to
Environmental

<PAGE>   77
                                     -54-

Laws, and shall also include without limitation all costs and expenses related
to Remedial Action. "Remedial Action" means any and all actions required (a) by
a Governmental Entity or by applicable Environmental Laws, (b) on account of a
Third Party Claim, (c) to respond to an event materially adversely affecting
the conduct of any of Seller's, Company's and/or CEVCO's business or (d) to
respond to an imminent and/or substantial hazard to human health or to the
Environment, to investigate, monitor, clean up, contain, cure, neutralize,
remediate, remove or treat any Release and shall comprise any actions required
under relevant Environmental Laws or Legal Requirements in respect of brine
wells at the Hauterives site.

         7.4 Environmental Survey. Prior to the date hereof, Seller and Buyer
have jointly retained Dames & Moore to perform an environmental assessment of
the Sites, including soil and groundwater sampling, in accordance with the
scope of work set forth at Schedule 7.4 hereto, in order to establish a
baseline with respect to the presence of certain Contaminants as of the Closing
Date (the "Survey"). A copy of the Survey is attached hereto as Schedule 7.4.

         7.5 Responsibility for Remedial Action. Subject to Sections 7.1 and
7.2 hereof, (a) Seller shall bear responsibility for Remedial Action relating
to (i) Non-Listed Contaminants; and (ii) Listed Contaminants, up to the
concentrations set forth in Schedule 7.5, unless and to the extent attributable
to the operation of Seller's business after the Closing Date, in which case
Seller shall bear such responsibility. Buyer shall bear responsibility for
Remedial Action relating to Listed Contaminants for the concentrations
exceeding the concentrations set forth in Schedule 7.5, unless and to the
extent attributable to the operation of Seller's business after the Closing
Date, in which case Seller shall bear such responsibility. In the event that
Remedial Action is conducted for Common Contaminants that are attributable to
the conduct of both Company's (and/or CEVCO's) business and Seller's business
(other than through Seller's interests in Company or CEVCO), responsibility for
such Remedial Action shall be shared between Company and Seller in proportion
to the respective responsibility of Company's, CEVCO's and/or Seller's business
for such Release. Any dispute regarding the allocation of responsibility of
Listed Contaminants that cannot 

<PAGE>   78
                                     -55-


be resolved by good faith negotiation among the parties within thirty (30) days
after any party has delivered the other party written notice of the dispute,
shall be submitted to such independent environmental consultant as may be
mutually agreed between Buyer and Seller. Said consultant shall, in reliance
upon the conclusions of the Survey and any other information the consultant
chooses to rely on, including new information developed at the Sites through
additional investigation, make a determination as to the appropriate allocation
of responsibility for Remedial Action, based upon its evaluation of the
respective responsibilities of the parties as regards the relevant Releases
that are subject of the Remedial Action. If said consultant can not determine
the origin of the Release(s) of Listed Contaminants, and as a result, the
proportion of the respective responsibility of Company's, CEVCO's and/or
Seller's business for such Release(s), then responsibility for such Remedial
Action shall be shared equally between Company and Seller. If Seller and Buyer
can not agree on the choice of such consultant within a period of thirty (30)
days, or if the consultant mutually chosen by Seller and Buyer shall not accept
such mission, either party shall be entitled to request the designation of an
independent environmental consultant by the President of the Court of Commerce
of Nanterre. The fees and expenses of such consultant shall be shared equally
by Seller and Buyer.

         (b) Notwithstanding anything herein to the contrary, any Environmental
Indemnifiable Losses (to the extent that such Environmental Indemnified Losses
relate to Remedial Action(s)) arising from or relating to the Sites
attributable to the operation of Company during joint ownership shall be
allocated in accordance with the portion of shares owned by Buyer and Seller.

         (c) It is understood and agreed between the parties that if and to the
extent a Remedial Action is required pursuant to a change in Environmental Law
after the Closing Date, the portion of the Environmental Indemnifiable Loss
resulting from such change in Environmental Law shall be borne by Company.

         (d) Buyer shall inform Seller promptly of (i) the results of all
non-routine measurements and sampling of Contaminants on the Sites as may be
undertaken by or on behalf of Buyer, 

<PAGE>   79

                                     -56-

Company, CEVCO or their Affiliates, (ii) any material Release, and (iii) any
changes in the use of raw materials and/or industrial procedures or processes,
at the Sites from and after the Closing Date to the extent such measurement,
Release or changes may be relevant to the allocation of responsibility between
Buyer and Seller under Section 7.5(a) hereof. Buyer, Company, CEVCO or their
Affiliates shall use its Best Efforts to keep Seller informed of any action
with relevant Governmental Entities or any building work or action that may
give rise to an enquiry, proceeding or claim with respect to an Environmental
Indemnifiable Loss unless Buyer, Company, CEVCO or their Affiliates shall have
previously consulted with Seller in such regard. To the extent such changes in
the use of raw materials or industrial procedures or processes are considered
by Buyer and Seller to be relevant to the allocation of responsibility between
Buyer and Seller under Section 7.5(a) hereof, either party may require that an
independent environmental consultant, to be mutually agreed upon by Buyer and
Seller, be retained to conduct a new environmental Site(s) assessment to
establish a new baseline for the allocation of responsibility between Buyer and
Seller pursuant to Section 7.5(a) hereof. If Seller and Buyer can not agree on
the choice of such consultant within a period of thirty (30) days, or if the
consultant mutually chosen by the Seller and Buyer shall not accept such
mission, either party shall be entitled to request the designation of an
independent environmental consultant by the President of the Court of Commerce
of Nanterre. The fees and expenses of the consultant shall be shared equally by
Seller and Buyer.

         7.6 Procedures with Respect to Remedial Actions.

         (a) Subject to the terms and conditions of Section 6.5 hereof, if a
Third Party Claim is made against an Indemnified Party with respect to an
Environmental Indemnifiable Loss, the Indemnifying Party shall be entitled to
discuss and negotiate with the relevant third party or Governmental Entity as
regards the Third Party Claim and in particular as regards any proposed
Remedial Action, it being understood that the Indemnified Party shall also have
the right to participate in such discussions and negotiations. To this effect,
the Indemnified Party shall promptly inform the Indemnifying Party of any
pending or threatened claim or enforcement action, and notify in advance 

<PAGE>   80

                                     -56-

and afford the Indemnifying Party the opportunity to participate in any
proposed meeting or discussion with such third party or Governmental Entity.
The Indemnified Party shall also provide to the Indemnifying Party all relevant
information and documents received from such third party or Governmental Entity
as required by Section 6.5 hereof.

         (b) The Indemnifying Party shall be entitled to monitor or cause an
independent consultant of its choice to monitor the conduct of the Remedial
Actions. Before initiating any Remedial Action, the Indemnified Party shall
prepare, with the input of the Indemnifying Party, a written document
describing in detail the scope, nature, methodology and estimated cost of
Remedial Actions to be taken (the "Plan"). Preparation of the Plan shall be
deemed a Remedial Action. The Plan shall be prepared in accordance with
Environmental Laws and shall not unreasonably interfere with the conduct of
business of the Indemnified Party. Unless otherwise agreed between the parties,
the Indemnified Party shall be the entity in charge of the conduct of the
Remedial Actions. The Indemnifying Party shall not be liable to indemnify the
Indemnified Party for any and all Remedial Actions made outside the scope of
the Plan. Any dispute regarding the Plan that cannot be resolved by good faith
negotiation among the Indemnifying Party and the Indemnified Party shall be
submitted to such independent environmental consulting firm as may be mutually
agreed between the Indemnifying Party and Indemnified Party. The Indemnified
Party may commence implementation of the Plan prior to the resolution of any
dispute regarding the Plan and shall be indemnified in accordance with the
terms of this Article 7 for the costs incurred in implementing (i) the
nondisputed sections of the Plan and (ii) the disputed sections of the Plan to
the extent approved by the independent environmental consulting firm. If the
Indemnifying Party and Indemnified Party can not agree on the choice of such
independent environmental consulting firm within a period of thirty (30) days,
or if the independent environmental consulting firm mutually chosen by the
parties shall not accept such mission, either party shall be entitled to
request the designation of an independent environmental consulting firm by the
President of the Court of Commerce of Nanterre. The fees and expenses of such
independent environmental consulting firm shall be shared equally by the
Indemnifying Party and Indemnified Party.

<PAGE>   81

                                     -58-


         (c) In the event of an imminent hazard to human health or the
Environment, Company or Seller may initiate a Remedial Action without a Plan as
it deems appropriate under the circumstances. The party responding to the
imminent hazard shall promptly notify the other party of the hazard and its
response to the hazard. Such Remedial Action shall be subject to the
indemnification provisions of this Article 7, insofar as subsequently ratified
by the Indemnifying Party, or in the event of dispute, through the dispute
resolution procedures in Section 7.6(b) hereof. After the imminent hazard has
been abated, any follow-up Remedial Actions shall be performed pursuant to
Section 7.6(b) hereof.

         7.7 Access. (a) Seller shall be entitled to visit the Real Property
and the Division at least four times a year at dates mutually agreed with
Buyer, during the period of survival of indemnification defined at Section 7.9
below.

         (b) Until such time as Company has received, in its name, Classified
Installation Permits for its operating facilities, Seller and Buyer shall
ensure that the manager of Seller's facility at Pont de Claix ("directeur
d'etablissement") shall have reasonable access to Company's operating
facilities to ensure compliance with Environmental Laws, and this manager shall
have the responsibility and authority to make decisions with respect Company's
operations and give instructions to Company employees in the event of imminent
hazards to human health and the environment.

         7.8 Limitations on Environmental Indemnification.

         (a) Notwithstanding any other provision of this Agreement, neither
Seller nor Buyer shall be entitled to make a claim under Section 7.1 or 7.2
hereof, unless and until the aggregate amount of Environmental Indemnifiable
Losses suffered by Seller or Buyer respectively, or Company and/or CEVCO
exceeds three million French Francs (FF 3,000,000), in which event Seller and
Buyer may assert their rights to indemnification thereunder to the full amount
of the Environmental Indemnifiable Loss.

<PAGE>   82
                                     -59-


         (b) Subject to the provisions of Section 7.5 hereof, the aggregate
indemnification obligations of Seller for any Environmental Indemnifiable
Losses resulting from a Remedial Action relating to a Release of Division
Contaminants shall not exceed 50% of the Total Enterprise Value and Seller's
indemnification obligation for any such individual Remedial Action shall not
exceed the percentage of the amount of any such Environmental Indemnifiable
Loss set forth in Schedule 7.8(b) hereto. The indemnification obligations of
Seller for any Environmental Indemnifiable Losses resulting from a breach of
representation or warranty contained in Section 2.1.17 hereof shall not exceed
three hundred fifty million French Francs (FF 350,000,000). The indemnification
obligations of Seller for any Environmental Indemnifiable Losses resulting from
a Remedial Action relating to a Release of Non-Listed Contaminants or Common
Contaminants shall not be capped. Subject to the provisions of Section 7.5
hereof, the aggregate indemnification obligations of Buyer for any
Environmental Indemnifiable Losses resulting from a Remedial Action relating to
a Release of Division Contaminants shall not exceed 50% of the Total Enterprise
Value. The indemnification obligations of Buyer for any Environmental
Indemnifiable Losses resulting from a Remedial Action relating to a Release of
Common Contaminants shall not be capped.

         7.9 Survival of Indemnification.

         (a) The right of Buyer to make a claim for Environmental Indemnifiable
Losses resulting from a Remedial Action relating to Division Contaminants shall
survive the Closing Date for a period of ten (10) years. The right of Buyer to
make a claim for Environmental Indemnifiable Losses resulting from a breach of
representation or warranty contained in Section 2.1.17 hereof shall survive the
Closing Date for a period of five (5) years. The right of Buyer to make a claim
for Environmental Indemnifiable Losses resulting from a Remedial Action
relating to Non-Listed Contaminants or Common Contaminants shall survive the
Closing Date and shall have no termination date.

         (b) The right of Seller to make a claim for Environmental
Indemnifiable Losses resulting from a Remedial Action relating to Division
Contaminants shall survive the Closing Date for a period of ten (10) years

not be precluded after the expiration of such period from bringing any action

Indemnifying Party shall not disqualify such Indemnified Party from receiving
indemnification from such Indemnifying Party and shall not constitute a breach

materially and adversely affects the ability of the Indemnifying Party to
defend against any such claim.

assigns harmless from and against any and all Environmental Indemnifiable
Losses (as defined in Section 7.3 of this Agreement) suffered or incurred by
Seller as permittee of the Classified Installation Permit for the Pont de Claix
facility and arising or resulting solely from the acts of Company; provided,
however, that Company shall have no obligation to indemnify Seller insofar as
such Indemnifiable Losses are attributable to the actions or inactions of
Seller.

         7.11 Saint Fons Facility. Subject to Section 7.8 hereof, Seller shall
indemnify and hold Buyer and Company and their respective officers, directors,
employees, agents, successors and assigns harmless from and against any and all
Environmental Indemnifiable Losses resulting or arising from the operation of
the Saint Fons facility prior to the Closing Date. The indemnification

other currency such party may in accordance with normal banking procedures
purchase the Specified Currency with such other currency; if the amount of the
Specified Currency so purchased is less than the amount originally due to such
party in the Specified Currency, the applicable party obligated to pay such
amount agrees, to the fullest extent that it may effectively do so, as a

currency.

                           Indemnifiable Disclosures


1. Seller shall indemnify and hold the Company harmless from and against any
Indemnifiable Losses incurred by the Company as a result of any failure to
complete the title formalities and procedures contemplated by the last sentence
of Section 2.1.8(b), subject to Section 6.6 (iii) hereof.

2. Seller shall indemnify and hold the Company harmless, subject to Section
6.4(a) and for a period of five (5) years from and after the Closing Date, from
and against Indemnifiable Losses incurred by the Company as a result of any
municipal order or injunction requiring the Company to effect improvements at
the Pont de Claix site, and based on the argument that the transfer of the
Conveyed Volume should have been effected by means of a lotissement in
accordance with French zoning and land regulation statutes. In determining the
amount of the resulting Indemnifiable Loss, the capital value of such
improvements shall be given due consideration. To the extent it can be
demonstrated that improvements would in all events have been required to be
undertaken by the Company or CEVCO within a three (3) year period after such
municipal order or injunction to comply with Environmental Laws or Legal
Requirements, the expenditures related to such improvements shall not be deemed
Indemnifiable Losses (a "but for test").

3. Seller shall indemnify and held the Buyer and the Company harmless from and
against any Indemnifiable Losses incurred by the Company or the Buyer as a
result of any claim by any Person arising under or in connection with the
Benefit Plans or any pension, retirement, bonus, profit sharing, stock
purchase, stock option, company savings or other benefit plans of Seller or any
of Seller's Affiliates, whether or not disclosed on Schedule 2.1.18(a) or (b)
or on Schedule 2.1.14 or on any of the other Schedules hereto, subject to
Section 6.6 (iii) hereof.

4. Seller shall indemnify and held the Buyer and the Company harmless from and
against any Indemnifiable Losses incurred by the Company or the Buyer as a
result of any claim in respect of, in connection with, or arising from, any
taxes, imposts, assessments, charges or duties imposed or imposable upon
Seller, the Company, CEVCO, the Division or their respective Affiliates or any
of their respective businesses or assets, unless otherwise specifically agreed
to the contrary herein, whether or not set forth on any Schedule hereto,
subject to Section 6.6 (iii) hereof.

5. Seller shall indemnify and held the Buyer and the Company harmless from and
against any Indemnifiable Losses incurred by the Company or the Buyer as a
result of any claim arising or that may arise, by virtue of the transactions
contemplated hereby and by the Related Agreements, under applicable bulk sales
laws or other laws protecting creditors against the transfer of Division and
CEVCO assets (including inventory and goods), subject to Section 6.6 (iii)
hereof.

6. Seller shall indemnify and held the Buyer and the Company harmless from and
against any Indemnifiable Losses incurred by the Company or the Buyer as a
result of any claim, action, lawsuit, arbitration, judicial or administrative
claim pending or threatened against Seller or the Company or against the assets
or business of the Division or the CEV business or any judgment, order or
decree entered in any lawsuit relating to the Division or the Company or CEVCO
or the CEV business (collectively "Litigation") (a) which relates to or arises
out of the conduct of the Division or the CEV prior to the Closing Date or (b)
which questions the Related Documents or the transactions contemplated hereby
or the consummation thereof provided however that with respect to Litigation
under paragraph (a) above, the survival periods set forth in Section 6.6 hereof
shall apply and be determined in accordance with the subject matter of such
Litigation.

                 LAROCHE INDUSTRIES INC. INTENDS TO ENTER INTO A
          CHLOR-ALKALI JOINT VENTURE IN EUROPE WITH RHONE POULENC

     ATLANTA - LaRoche Industries Inc. announces its intention to purchase 50%
interest in a European chlorine/caustic soda business.  The company has reached
a tentative understanding to enter into a joint venture with Rhone-Poulenc 
Chimie S.A. for the operation of chlorine, caustic soda and bleach 
manufacturing and distribution facilities in France.

     The two companies would each hold a 50% interest in a new joint venture
company which would operate the chlorine and caustic soda portion of Rhone
Poulenc's Pont de Claix plant.  LaRoche anticipates that the joint venture will
commence during the second half of 1997, after the definitive agreements have
been signed and after certain pre-closing conditions have been satisfied.

     The formation of the joint venture is consistent with LaRoche's operating
experience and corporate growth objectives.  The company anticipates that the
joint venture will also offer a unique opportunity for LaRoche's existing
chlorine and caustic soda facility in Gramercy, La., and the Pont de Claix
facility eventually to share information and technology.

     LaRoche Industries Inc. makes a diverse range of chemicals at seven
manufacturing facilities in the United States.  The company produces
electrochemicals such as chlorine and caustic soda for plastics, water
treatment, waste treatment and other chemical manufacturing processes.  LaRoche
manufactures and/or distributes nitrogen-based chemicals including anhydrous
ammonia, aqua ammonia, nitric acid, low density ammonium nitrate and nitrate
solutions for industrial applications.  Other nitrogen-based products, such as
high density ammonium nitrate, urea, UAN solutions, potash and phosphates, are
sold into U.S. agricultural markets. LaRoche also manufactures specialty
chemicals such as activated and Versal(TM) alumina for environmental and
chemical processing such as specialty adsorbents, catalysts and catalyst
supports, specialty  abrasives and other performance-critical applications, and
HCFC-141b for rigid foam insulation.

                 LAROCHE INDUSTRIES INC. FINALIZES CHLOR-ALKALI
               JOINT VENTURE IN FRANCE WITH RHONE-POULENC CHIMIE


     ATLANTA - LaRoche Industries Inc. announced today the closing of its
previously announced purchase of a 50% interest in ChlorAlp S.A.S., a French
joint venture company, which will manufacture and distribute chlorine, caustic
soda and bleach from its 265,000 ton-per-year facility in Pont-de-Claix,
France.  Rhone-Poulenc Chimie S.A., which previously owned the facility, will
own the remaining 50% interest in ChlorAlp.  LaRoche purchased its interest in
ChlorAlp through its newly formed, wholly owned subsidiary, LII Europe
S.A.R.L., which will manage LaRoche's interest in the joint venture.

     In addition to the facility and certain related assets, ChlorAlp owns a
60% interest in an entity owning a cogeneration powerhouse.  ChlorAlp's assets
also include certain rights over the production of brine extracted from brine
mines located in Hauterives, France, and the pipelines for transportation of
such brine, and bleach manufacturing facilities primarily located in St. Fons,
France.

     "We are very pleased with the formation of this joint venture," commented
President and C.E.O. Grant O. Reed.  "The formation of ChlorAlp marks LaRoche's
entry into European chemical manufacturing, and the operations in Pont-de-Claix
complement our lengthy experience in chlor-alkali production."

     LaRoche believes that the joint venture will increase the Company's
international market share in chlorine and caustic soda, provide a significant
entry point to the European chemical markets, and produce operating
efficiencies due to the similarities between the French facility and LaRoche's
chlor-alkali facility in Gramercy, La.

     LaRoche is a major diversified producer and distributor of inorganic
chemicals, including nitrogen products, electrochemical products and alumina
chemicals.
