CAIRO, June 2 (Reuters) - Egyptian authorities have presented an amended invitation for tobacco companies to bid for a licence to manufacture cigarettes, a document seen by Reuters showed, after four firms complained the terms were too narrow.

Under the new terms, sent to tobacco companies on June 1, the winning bidder should agree to produce 1 billion cigarettes per year instead of 15 billion per year.

Authorities have set a two-month deadline for companies wishing to submit their bids, the document from Egypt's Industrial Development Authority showed. (Reporting by Ehab Farouk; Writing by Nadine Awadalla; Editing by Aidan Lewis and Jan Harvey)
