Dear Employee,

RE: REPLACEMENT OF EMPLOYEE STOCK OPTIONS

As you know, from time to time our company grants options for the purchase of
company common stock to its employees as part of the overall package of salary,
benefits and incentives offered to them.

When the company makes such an option grant, it sets the option exercise price -
i.e. the amount which the employee must pay in order to convert one option to
one ordinary share - in accordance with the price of the company's shares on the
stock market at that time.

As a result of declines in the company's share price in recent years, many
employees now hold options whose exercise price is significantly higher than the
current market price of the shares. In other words, many options are currently
"out of the money" and it would not be worthwhile to exercise those options at
this time.

In light of these circumstances, the management of the company has decided to
undertake the replacement of existing options with new options whose exercise
price is $1.45.

As part of this initiative, all employees are requested to make an election
between two alternatives with regard to each option in their possession:

THE FIRST ALTERNATIVE: Leave the existing option unchanged - do not replace the
existing option and relinquish the right to receive a new option in its place.
In this case, all the terms and conditions of the existing option will continue
to apply, including the original vesting period and exercise price.

THE SECOND ALTERNATIVE: Accept the new option and cancel the existing option.
The new option will have an exercise price of $1.45 and vest over a period of
four years, in equal annual installments. The vesting period began as of May 17,
2006 - the date the new options were granted pursuant to a decision of the
company's board of directors.

As a consequence of electing the Second Alternative it is important to note that
the options you will receive will not be vested, but rather vest over the
aforementioned four year period.

We know of no adverse tax consequence that will impact any employee in the
United States with respect to the cancellation of your present options and grant
of new options. If you exchange your current options for new options, you will
not be required under current law to recognize income for federal income tax
purposes as a result of the exchange. The grant of options is not recognized as
taxable income under federal tax laws.

The options replacement is designed primarily to reduce the exercise price of
employee options so as to bring the exercise price in line with the current
level of the company share price - in order to increase the likelihood of
exercise in the future. Nevertheless, the option replacement involves certain
conditions, such as the restart of the vesting period.




Each employee who holds company stock options is requested to notify us of his
or her choice between the two alternatives through the website of Tamir Fishman
starting September 10, 2006 and ending SEPTEMBER 17, 2006 (instructions with
your user name and password will be sent by separate e-mail by Tamir Fishman).

If you only choose to replace a portion of the options you hold, please clearly
mark which options you are replacing.

Any employee who does not make the required notification by September 17, 2006
will be deemed to have elected the First Alternative, i.e. to continue to hold
all of his or her existing options WITHOUT cancellation and replacement.

For any further information you may contact Tziona Shriki - Finance department
The management of the company wishes you many more years of productive and
rewarding employment.

                                                        Sincerely,
                                                        Tower Semiconductor Ltd.

Dated:  September 2006

THIS EXCHANGE OFFER IS MADE FOR THE SECURITIES OF A FOREIGN COMPANY. THE OFFER
IS SUBJECT TO DISCLOSURE REQUIREMENTS OF A FOREIGN COUNTRY THAT ARE DIFFERENT
FROM THOSE OF THE UNITED STATES.

IT MAY BE DIFFICULT FOR YOU TO ENFORCE YOUR RIGHTS AND ANY CLAIM YOU MAY HAVE

                                                                       EXHIBIT B

Dear Employee,

RE: REPLACEMENT OF EMPLOYEE STOCK OPTIONS

As you know, from time to time our company grants options for the purchase of
company common stock to its employees as part of the overall package of salary,
benefits and incentives offered to them.

When the company makes such an option grant, it sets the option exercise price -
i.e. the amount which the employee must pay in order to convert one option to
one ordinary share - in accordance with the price of the company's shares on the
stock market at that time.

As a result of declines in the company's share price in recent years, many
employees now hold options whose exercise price is significantly higher than the
current market price of the shares. In other words, many options are currently
"out of the money" and it would not be worthwhile to exercise those options at
this time.

In light of these circumstances, the board of directors of the company has
decided to undertake the replacement of existing options with new options whose
exercise price is $1.45.

As part of this initiative, all employees are requested to make an election
between two alternatives with regard to each option in their possession:

THE FIRST ALTERNATIVE: Leave the existing option unchanged - do not replace the
existing option and relinquish the right to receive a new option in its place.
In this case, all the terms and conditions of the existing option will continue
to apply, including the applicable tax rate on exercise and sale, the vesting
period, and the original exercise price.

THE SECOND ALTERNATIVE: Accept the new option and cancel the existing option.
The new option will have an exercise price of $1.45.

Electing the Second Alternative, i.e. choosing to replace the existing options,
has a number of important consequences outlined below:

     A.   The vesting period of the new options will be restarted commencing on
          May 17, 2006 - the date the new options were granted pursuant to the
          decision of the company's board of directors. Vesting of the new
          options will take place over a period of four years, in equal annual
          installments.




     B.   The new options will be subject to the terms of Israeli Income Tax
          Ordinance Section 102 (capital gains track). As a result, gains from
          the exercise of options and the sale of shares will be subject to
          income tax at a reduced rate of 25%, on condition that the sale will
          occur at least two years after the grant date, i.e. after May 17,
          2008.

     C.   Pursuant to the approval of the Israeli Tax Authority dated September
          4, 2006 ("the Approval"), with respect to existing options that were
          still UNVESTED on May 17, 2006, their cancellation and replacement
          with new options does NOT constitute a taxable event. With respect to
          existing options that HAD ALREADY VESTED before May 17, 2006, their
          cancellation and replacement will constitute a taxable event. The
          Approval specifies the economic value of each cancelled option for
          purposes of calculating the tax owing on such cancellation. The tax
          then imposed is the tax rate of the relevant cancelled option
          multiplied by such economic value. Please note that, in many cases,
          replacement of existing options will not result in any Israeli tax
          liability. You may find the data regarding you r personal options in
          the website mentioned below.

          The Israeli Tax Authority has agreed that the collection of the tax
          owing on the replacement of the existing options will be DEFERRED
          until the exercise of the new options, subject to the terms and
          conditions of the Approval.

          When new options are exercised and shares sold, the deferred tax owed
          in connection with the cancellation of existing options, including
          interest and CPI indexing thereon, will then be collected out of the
          net (after tax) proceeds of the exercise of the new options (in
          addition to the tax owing upon the exercise of the new options
          themselves). In any event, the deferred tax must be paid by May 17,
          2010 at the latest (or when your employment with the company
          terminates, if earlier), even if no new options are exercised by that
          date. Please note that you may choose to exchange only a portion of
          your existing options and in such case, you must clearly specify which
          options you wish to exchange. For example, you may decide to keep
          options that would otherwise be subject to tax liability in the event
          of exchange and only exchange those options that will not be subject
          to tax liability when cancelled.

To summarize, the options replacement is designed primarily to reduce the
exercise price of employee options so as to bring the exercise price in line
with the current level of the company share price - in order to increase the
likelihood of exercise in the future.

Nevertheless, the option replacement involves certain conditions such as the
restart of the vesting period and, in some cases, payment of tax in the future
in connection with the cancellation of the existing options.




Each employee who holds company stock options is requested to notify us of his
or her choice between the two alternatives through the website of Tamir Fishman
FROM SEPTEMBER 10, 2006 UNTIL SEPTEMBER 17, 2006. The website will specify a

decide to exchange all or any part of such options.
