	No. W ________	CUSIP No. M87915 217 

	 VOID AFTER 5:00 P.M., NEW YORK CITY TIME,

 ON MARCH 15, 2011, OR UPON EARLIER REDEMPTION 

        This
certifies that ________________________, or its registered assigns, is the registered
holder of _____________________ warrants to purchase certain securities (each a
“Warrant”). Each Warrant entitles the holder thereof, subject to the
provisions contained herein and in the Warrant Agreement (as defined below), to purchase
from Tower Semiconductor Ltd., an Israeli company (the “Company”), 1.8
Ordinary Shares of the Company (each a “Share”), at the Exercise Price
set forth below. The exercise price of for each Share (the “Exercise
Price”) shall be $2.78 as of September 19, 2008, subject to adjustments as set
forth in the Warrant Agreement (as defined below). 

        Subject
to the terms of the Warrant Agreement, each Warrant evidenced hereby may be exercised in
whole, but not in part, at any time, as specified herein, on any Business Day (as defined
below) occurring during the period (the “Exercise Period”) commencing on
March 15, 2007 and ending at 5:00 P.M., New York City time, on March 15, 2011 (the
“Expiration Date”). Each Warrant remaining unexercised after 5:00 P.M.,
New York City time on the Expiration Date shall become void, and all rights of the holder
of this Warrant Certificate evidencing such Warrant shall cease. 

        The
holder of the Warrants represented by this Warrant Certificate may exercise any Warrant
evidenced hereby by delivering, not later than 5:00 P.M., New York City time, on any
Business Day during the Exercise Period to Continental Stock Transfer & Trust Company
(the “Warrant Agent”, which term includes any successor warrant agent
under the Warrant Agreement described below) at its corporate trust department at 17
Battery Place, New York, NY 10004, (i) this Warrant Certificate and the Warrants to be
exercised (the “Book-Entry Warrants”) free on the records of The
Depository Trust Company (the “Depository”) to an account of the Warrant
Agent at the Depository designated for such purpose in writing by the Warrant Agent to the
Depository, (ii) an election to purchase (“Election to Purchase”),
substantially in the form included on the reverse hereof, as applicable (A) by the holder
hereof on the reverse of this Warrant Certificate or (B) properly executed by the
institution in whose account the Warrant is recorded on the records of the Depository (the
“Participant”) and (iii) the Exercise Price for each Warrant to be
exercised in lawful money of the United States of America by certified or official bank
check or by bank wire transfer in immediately available funds[; provided, however,
that at any time after the Company has given a Redemption Notice (as defined herein), the
holder hereof may, in lieu of payment of the Exercise Price, surrender its Warrant for
that number of Shares equal to the quotient obtained by dividing (x) the product of (1)
the number of Shares underlying the surrendered Warrant and (2) the difference between the
Fair Market Value (defined below) and the Exercise Price, by (y) the Fair Market Value.
The “Fair Market Value” shall mean the average reported last sale price
of the Shares for the 10 trading days ending on the 3rd trading day prior to the date on
which the Redemption Notice is sent to holders of the Warrants]1. If any of
(a) this Warrant Certificate or the Book-Entry Warrants, (b) the Election to Purchase, or
(c) the Exercise Price therefor, is received by the Warrant Agent after 5:00 P.M., New
York City, the Warrants will be deemed to be received and exercised on the Business Day
next succeeding the date such items are received and such date shall be the Exercise Date
for purposes hereof. If the date such items are received is not a Business Day, the
Warrants will be deemed to be received and exercised on the next succeeding day which is a
Business Day and such date shall be the Exercise Date for purposes hereof. If the Warrants
to be exercised are received or deemed to be received after the Expiration Date, the
exercise thereof will be null and void and any funds delivered to the Warrant Agent will
be returned to the holder as soon as practicable. In no event will interest accrue on
funds deposited with the Warrant Agent in respect of an exercise or attempted exercise of
Warrants. The validity of any exercise of Warrants will be determined by the Warrant Agent
in its sole discretion and such determination will be final and binding upon the holder of
the Warrants and the Company. Neither the Warrant Agent nor the Company shall have any
obligation to inform a holder of Warrants of the invalidity of any exercise of Warrants. 

        As
used herein, the term “Business Day” means any day that is not a Saturday
or Sunday and is not a United States federal holiday or a day on which banking
institutions generally are authorized or obligated by law or regulation to close in New
York City. 

        Warrants
may be exercised only in whole numbers of Shares. No fractional Shares are to be issued
upon the exercise of any Warrant, but rather the number of Shares to be issued shall be
rounded up to the nearest whole number. If fewer than all of the Warrants evidenced by
this Warrant Certificate are exercised, a new Warrant Certificate for the number of
Warrants remaining unexercised shall be executed by the Company and countersigned by the
Warrant Agent, as provided in Section 2 of the Warrant Agreement, and delivered to the
holder of this Warrant Certificate at the address specified on the books of the Warrant
Agent or as otherwise specified by such Registered Holder.

Warrant Agent and at the office of the Company at Ramat Gavriel Industrial Area, P.O. Box
619, Migdal Haemek Israel 23105, Attention: Chief Financial Officer. 

        At
any time during the Exercise Period, the Company may, at its option, redeem all (but not
part) of the then outstanding Warrants upon giving notice in accordance with the terms of
the Warrant Agreement (the “Redemption Notice”), at a price of $0.01 per
Warrant (the “Redemption Price”); provided, that the last sales price of
the Shares is at least $4.72 per Share, for any twenty (20) trading days within a thirty
(30) trading day period ending on the third Business Day prior to the date on which the
Redemption Notice is given. In the event the Company shall elect to redeem all of the then
outstanding Warrants, the Company shall fix a date for such redemption (the
“Redemption Date”); provided, that such date shall occur prior to
the expiration of the Exercise Period. The Warrants may be exercised in accordance with
the terms of this Agreement at any time after a Redemption Notice shall have been given by
the Company; provided, however, that no Warrants may be exercised subsequent
to the expiration of the Exercise Period; provided, further, that all rights
with respect to the Warrants shall cease on the Redemption Date, other than to the right
to receive the Redemption Price.  

        The
accrual of dividends, if any, on the Shares issued upon the valid exercise of any Warrant
will be governed by the terms generally applicable to such Shares. From and after the
issuance of such Shares, the former holder of the Warrants exercised will be entitled to
the benefits generally available to other holders of Shares and such former holder’s
right to receive payments of dividends and any other amounts payable in respect of the
Shares shall be governed by, and shall be subject to, the terms and provisions generally
applicable to such Shares. 

        The
Exercise Price and the number of Shares purchasable upon the exercise of each Warrant
shall be subject to adjustment as provided pursuant to Section 4 of the Warrant Agreement. 

        Upon
due presentment for registration of transfer or exchange of this Warrant Certificate at
the stock transfer division of the Warrant Agent, the Company shall execute, and the
Warrant Agent shall countersign and deliver as provided in Section 5 of the Warrant
Agreement, in the name of the designated transferee, one or more new Warrant Certificates
of any authorized denomination evidencing in the aggregate a like number of unexercised
Warrants, subject to the limitations provided in the Warrant Agreement.

        Neither
this Warrant Certificate nor the Warrants evidenced hereby shall entitle the holder hereof
or thereof to any of the rights of a holder of the Shares, including, without limitation,
the right to receive dividends, if any, or payments upon the liquidation, dissolution or
winding up of the Company or to exercise voting rights, if any. 

        The
Warrant Agreement and this Warrant Certificate may be amended as provided in the Warrant
Agreement including, under certain circumstances described therein, without the consent of
the holder of this Warrant Certificate or the Warrants evidenced thereby. 

        THIS
WARRANT CERTIFICATE AND ALL RIGHTS HEREUNDER AND UNDER THE WARRANT AGREEMENT SHALL BE
GOVERNED BY AND INTERPRETED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW

valid or obligatory for any purpose, and no Warrant evidenced hereby may be exercised,
unless this Warrant Certificate has been countersigned by the manual signature of the
Warrant Agent.

EXHIBIT 4.4  

ASSUMPTION AGREEMENT  

        This
Assumption Agreement (this “Assumption Agreement”) is entered into as of
September 19, 2008, by and among Jazz Technologies, Inc. (previously named Acquicor
Technology Inc.), a Delaware corporation (the “Company”), Tower Semiconductor
Ltd., an Israel company (“Parent”), and Continental Stock Transfer &
Trust Company, a New York corporation (the “Warrant Agent”).  

        WHEREAS,
the Company and the Warrant Agent are parties to that certain Warrant Agreement dated as
of March 15, 2006 (as clarified by that certain Warrant Clarification Agreement dated as
of November 9, 2006, the “Warrant Agreement”; capitalized terms used but
not otherwise defined herein shall have the meanings given to such terms in the Warrant
Agreement); 

        WHEREAS,
Parent, Armstrong Acquisition Corp., a Delaware corporation and a wholly owned subsidiary
of Parent (“Merger Sub”), and the Company are parties to that certain
Agreement and Plan of Merger and Reorganization dated as of May 19, 2008 (the
“Merger Agreement”), pursuant to which, subject to the terms and
conditions set forth therein, Merger Sub has agreed to merge with and into the Company,
with the Company being the surviving corporation and a wholly owned subsidiary of Parent
(the “Merger”); 

        WHEREAS,
pursuant to the Merger Agreement, at the effective time of the Merger (the
“Effective Time”), by virtue of the Merger and without any further action
on the part of Parent, Merger Sub, the Company or any stockholder of the Company, each
share of Common Stock outstanding immediately prior to the Effective Time shall be
converted into the right to receive 1.8 ordinary shares, par value NIS 1.00 per share, of
Parent (“Parent Ordinary Shares”); and 

        WHEREAS,
pursuant to Section 4.4 of the Warrant Agreement and Section 4.9(b) of the Merger
Agreement, upon the Effective Time, each outstanding Warrant will be assumed by Parent and
will continue to have, and be subject to, the same terms and conditions of such Warrant
immediately prior to the Effective Time, except that, in accordance with Section 4.4 of
the Warrant Agreement, (i) each Warrant will be exercisable for that number of Parent
Ordinary Shares equal to the product of the number of shares of Common Stock that were
issuable upon exercise of such Warrant immediately prior to the Effective Time multiplied
by 1.8, and (ii) the per share exercise price for the Parent Ordinary Shares issuable upon
exercise of such assumed Warrant will be equal to the quotient determined by dividing the
exercise price per share of Common Stock at which such Warrant was exercisable immediately
prior to the Effective Time by 1.8. 

1

        NOW,
THEREFORE, in consideration of the foregoing and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the Company,
Parent and the Warrant Agent hereby agree as follows: 

         1.       
          Assignment and Assumption. 

		    (a)        Upon
the Effective Time, the Company hereby assigns, and Parent hereby assumes,           the
rights and obligations of the Company under the Warrant Agreement and the
          Warrants, including the obligation to issue Parent Ordinary Shares upon the
          exercise of the Warrants, and Parent hereby agrees to faithfully perform,
          satisfy and discharge when due, the liabilities and obligations of the Company
          under the Warrant Agreement and the Warrants.  

		    (b)        Parent
acknowledges and agrees that subject to the terms of the Warrant           Agreement, the
Warrants and this Assumption Agreement, the Warrant Agreement and           the Warrants
shall continue in full force and effect and that all of the           Company’s
obligations thereunder shall be valid and enforceable as against           Parent upon
consummation of the Merger and shall not be impaired or limited by           the
execution or effectiveness of this Assumption Agreement. Parent represents           that
it has taken all corporate action necessary to reserve for issuance a
          sufficient number of Parent Ordinary Shares for delivery upon exercise of
          assumed Warrants on the terms set forth herein and in the Merger Agreement.  

		    (c)        This
Assumption Agreement is being executed and delivered pursuant and subject           to
the Warrant Agreement. Nothing in this Assumption Agreement shall, or shall           be
deemed to, defeat, limit, alter, impair, enhance or enlarge any right,
          obligation, claim or remedy created by the Warrant Agreement or any other
          document or instrument delivered pursuant to or in connection with it.  

         2.       
          Miscellaneous. 

		    (a)        Governing
Law. The validity, interpretation, and performance of this Assumption Agreement and
of the Warrants shall be governed in all respects by the laws of the State of New York,
without giving effect to conflicts of law principles that would result in the application
of the substantive laws of another jurisdiction. Parent hereby agrees that any action,
proceeding or claim against it arising out of or relating in any way to this Assumption
Agreement shall be brought and enforced in the courts of the State of New York or the
United States District Court for the Southern District of New York, and irrevocably
submits to such jurisdiction, which jurisdiction shall be exclusive. Parent hereby waives
any objection to such exclusive jurisdiction and that such courts represent an
inconvenient forum. Any such process or summons to be served upon Parent may be served by
transmitting a copy thereof by registered or certified mail, return receipt requested,
postage prepaid, addressed to it at the address set forth below:

Agreement which are not inconsistent with this Assumption Agreement shall remain in full
force and effect. This Assumption Agreement may be executed in counterparts.

unenforceability of any term or provision hereof shall not affect the validity or
enforceability of this Assumption Agreement or of any other term or provision hereof.

hereto intend that there shall be added as part of this Assumption Agreement a provision
