Nature of operations. Syngenta AG is a world leading crop protection and seeds business that is involved in the discovery, development, manufacture and marketing of a range of agricultural products designed to improve crop yields and food quality. Syngenta is headquartered in Basel, Switzerland and was formed by Novartis AG ("Novartis") and AstraZeneca PLC ("AstraZeneca") through an agreement to spin off and merge the Novartis crop protection and seeds businesses with the Zeneca agrochemicals business to create a dedicated agribusiness company whose shares were then the subject of a global offering (the "Transactions"). The Transactions were completed on November 13, 2000 (the "Transaction Date"). In this annual report, for periods prior to November 13, 2000, we refer to the businesses contributed by Novartis as the "Novartis agribusiness"; and we refer to the businesses contributed to Syngenta by AstraZeneca as the "Zeneca agrochemicals business" (p i)."

May 9, 2000 - Novartis: Form 20-F/A. US Securities & Exhange Commission.
New products in development: Butafenacil, Clodinafop, Fludioxonil (Apron), Fluthiacet, Metolachlor, Trifloxystrobin, Trifloxysulfuron. Note: "The Company was created by the merger of Sandoz AG and CIBA-Geigy AG (the "Merger") in December 1996. Prior to the Merger, Sandoz AG and CIBA-Geigy AG were each global participants in the pharmaceutical and agrochemical industries. The predecessor companies of the Company merged to realize sales, cost and cross-sector synergies, and to create a combined entity with the resources and ability to compete in the long term in an increasingly competitive global environment. The Boards of the Company and AstraZeneca announced on December 2, 1999, that they each agreed to spin off and merge Novartis Crop Protection and Seeds businesses and Zeneca Agrochemicals to create the world's first dedicated agribusiness company with pro forma combined sales in 1998 of approximately $7.9 billion. The new company will be named Syngenta AG ("Syngenta"), headquartered in Basel, Switzerland (p 5)... In Crop Protection, the major production sites for the active ingredients are located in India, Switzerland, the UK and the U.S., with the major production sites for formulation and packaging in Brazil, China, France, South Korea, Switzerland and the U.S. (p 36)... Agribusiness. On September 1, 1998, Novartis acquired a production plant and related operating assets from Oriental Chemicals Industries, South Korea for CHF 196 million (p F-13)."
