              TOWER SEMICONDUCTOR IMPLEMENTS A COST REDUCTION PLAN

ACTIONS TAKEN TO IMPROVE TOWER'S MARGINS ON ITS ROAD TO PROFITABILITY

MIGDAL HAEMEK, Israel, December 4, 2007 - Tower Semiconductor Ltd. (NASDAQ:
TSEM; TASE: TSEM), an independent specialty foundry, today announced it has
initiated a cost-reduction plan designed to improve its future gross, operating
and net margins in fiscal year 2008 and beyond.

Tower has expanded its manufacturing capacity by more than 50 percent over the
past several quarters and has increased its customer base and product portfolio,
resulting in a quarterly sales run rate of nearly three times the mid 2005 run
rate. Furthermore, production volumes have been growing consistently. Thus, in
order to satisfy exceeding demand from its customers, the company recently
announced a further expansion of its Fab2 capacity to be completed in 2008. In
addition to the expected financial margins improvement from this growth plan,
the company also drives a comprehensive, proactive cost-reduction plan that
should result in approximately $20 million annual cost savings.

During fiscal year 2007, Tower already executed a number of cost-reduction
activities that drove down the Fab2 production cost per wafer by 25%, primarily
due to the volume ramp that was accomplished while maintaining non-operational
headcount almost flat, coupled by operational efficiency improvements.
Furthermore, Tower implemented a plan to outsource the management of spare parts
inventories to EMA, as announced in August 2007. These cost reduction measures,
coupled with the three times growth is sales, enabled Tower to record positive
EBITDA for the past 8 quarters and positive cash from operations for the past 4
quarters. Furthermore, Tower's improved financial and cash situation enables
greater operational flexibility as well as funding of its capacity ramp-up.

On an immediate basis, in order to maximize the financial benefits in fiscal
year 2008 and beyond, Tower is to take the following additional cost saving
measures:

     o    Payroll cost savings of greater than $5 million per annum are expected
          to be accomplished through a combination of reduction in jobs,
          primarily in non-operational and service related functions,
          outsourcing non core functions, as well as internal transitions and
          organizational changes. Such actions should result in stronger focus
          on close customer support.





     o    Materials costs savings of greater than $10 million per annum are
          expected to be accomplished through multiple sourcing of materials and
          spare parts by several vendors, substitution of expensive materials
          and parts by less expensive alternatives as well as price negotiations
          with suppliers.

     o    Sustained capital expenditures are expected to be reduced through
          better program efficiencies and longer term win-win alignments with
          key suppliers.

     o    Major saving in period cost by acquiring used tools from winding-down
          Fabs of Intel and AMD for the capacity expansion. These tools are
          bought at prices which are significantly below new tools prices,
          thereby allowing short period of return on investment from these tools
          acquisitions.

"While we continue our expansion and project further growth in sales, we are
mindful to continuously promote and improve corporate efficiencies", said
Russell Ellwanger, CEO of Tower Semiconductor. "Every measure is taken to
accomplish the aggressive cost reduction goals whilst improving Tower's ability
to perform and deliver. We are confident that these measures, coupled with the
business expansion initiatives, result in a stronger and more competitive Tower
and hence help accelerate our move to profitability."
