In addition, from the start of production at the facility, TowerJazz will be entitled to capacity allocation of up to 50% of the targeted 40,000 wafer per month fab capacity, which it may decide to use at its discretion. This capacity will provide TowerJazz with additional manufacturing capability and flexibility to address its growing global demand.
