Officials said Thursday the deal will pay the state $150,000 annually for the first three years, with a two-year renewal option for $175,000 per year.
Giant will be the official sponsor of Exposition Hall and will have a display during the Farm Show that features Pennsylvania vendors.
The state isn't yet disclosing the improvements that the sponsorship money will fund.
The 103rd Farm Show runs Jan. 5-12. This year's theme is "inspiring Pennsylvania's story."
