All of the covenants and obligations that the Purchaser is required to perform
or to comply with pursuant to this Agreement at or prior to the Closing must

transactions contemplated hereby.

8.     UNWINDING

8.1    UNWINDING CONDITIONS

This Agreement may be unwound (a) by mutual consent of the Sellers and the
Purchaser, (b) by the Purchaser, if the Completion of the Demerger has not taken
place before or at 18 July 2001 and provided the Purchaser has not decided that
the Closing shall take place irrespectively of the Completion of the Demerger,
or (c) by either of the Sellers or the Purchaser, upon five business days prior
written notice, if the conditions set forth in Section 4, 5 and 6 of this
Agreement are not met within 120 days after the date of signing of this
Agreement and the Escrow Account Agreement, provided however, that (i) the
Sellers may not demand unwinding pursuant to (c) above if the non fulfilment of
the conditions in Sections 4, 5 and 6 results from the non Completion of the
Demerger, and (ii) neither the Sellers nor the Purchaser may demand the
unwinding pursuant to (c) above if the non fulfilment of the conditions in
Sections 4, 5 and 6 resultsdirectly or indirectly from breach of any provision

unwind this Agreement.

                                                                              13

9.1    TERMINATION EVENTS

This Agreement may be terminated:

a.     by either the Sellers or the Purchaser, upon 5 business days prior
       written notice to the other, within 90 days after Closing if a breach of
       any provision of this Agreement has been committed by the other Party,
       such breach has not been waived and such breach is material to the
       transactions contemplated hereby or to the business, assets, financial
       condition or prospect of the Company taken as a whole;

b.     by mutual consent of the Sellers and the Purchaser.

Notification under this Article must, in order to be valid, be given without

10.    INDEMNIFICATION BY THE SELLERS

10.1   INDEMNIFICATION AND PAYMENT OF DAMAGES BY THE SELLERS

The Sellers shall, pro rata, indemnify and hold harmless the Purchaser for any

costs of investigation and defence and reasonable attorneys' fees), diminution
of value or otherwise, arising, directly from:

(a)    any breach of any of the warranties made by the Sellers in Section 3, and

reasonable detail to the extent then known by the Purchaser, provided, however,
that such notice in respect of a claim based on breach of the warranty in
Section 3.14 and Section 3.16, compliance with laws and environment, may be made
as long as the Company may be exposed to any liability according to applicable
law; and further provided that a claim based on breach of the warranty in
