STOCK EXCHANGE NOTICE

DOMESTIC EQUITY MARKET
SYNGENTA AG ('SYNGENTA')

1. Listing particulars have been filed in relation to the global secondary
offering of ordinary shares in Syngenta.  Syngenta will be formed through the
combination of the de-merged agrochemicals business of AstraZeneca plc and the
agribusiness of Novartis AG.  Subject to approval by the UK Listing Authority,
Syngenta will obtain a secondary listing in London and will be admitted to
trading on the London Stock Exchange on 13 November 2000.  

2. As a Swiss incorporated company with a primary listing in Zurich, Syngenta
would normally be classified as a European equity market security and be
quoted on SEAQ International.  However, given the expectation of high trading
volumes in London during the period immediately following admission, including
the anticipated level of UK retail participation, the Exchange has agreed
that, on an exceptional basis, Syngenta will be treated as a domestic equity
market security and will be traded on SEAQ with effect from 13 November 2000. 
This will ensure the appropriate level of visibility and accessibility for
those member firms wishing to trade this security on the London Stock
Exchange.  The Exchange will review the ongoing suitability of the quotation
on SEAQ after the initial period of trading.

3. In light of its treatment as a domestic equity market security, all trading
and reporting obligations, as set out within chapters 4 and 8 of the Rules of
the London Stock Exchange, will apply.


Andrew McStravick
Head of Market Operations

Any queries relating to the application of the Exchange's rules should be
addressed to Mathew Wootton, Regulatory Development, telephone [phone]
