AMSTERDAM, April 22 (Reuters) - ASML has signed a declaration of intent for a major expansion in the Dutch city of Eindhoven, spokespeople for the city and the largest supplier of equipment to computer chip makers said on Monday, although a deal has yet to be finalised.

The decision follows an announcement last month that the Dutch government would

spend $2.7 billion

to improve infrastructure in the Eindhoven region to prevent the company from moving significant operations abroad. (Reporting by Toby Sterling, Writing by Charlotte Van Campenhout, Editing by Benoit Van Overstraeten and Louise Heavens)
