                               AMIS HOLDINGS, INC.
                 AMENDED AND RESTATED 2000 EQUITY INCENTIVE PLAN

                      RESTRICTED STOCK UNIT AWARD AGREEMENT

     Pursuant to your Restricted Stock Unit Award Notice (the "AWARD NOTICE")
and this Restricted Stock Unit Award Agreement (this "AGREEMENT"), AMIS
Holdings, Inc. (the "COMPANY") has granted you a Restricted Stock Unit Award
(the "AWARD") under its Amended and Restated 2000 Equity Incentive Plan (the
"PLAN") for the number of Restricted Stock Units indicated in your Award Notice.
Capitalized terms not explicitly defined in this Agreement but defined in the
Plan shall have the same definitions as in the Plan.

     The details of the Award are as follows:

1.   VESTING

     The Award will vest and become payable according to the vesting schedule
set forth in the Award Notice (the "VESTING SCHEDULE"). One share of the
Company's Common Stock will be issuable for each Restricted Stock Unit that
vests and becomes payable. Restricted Stock Units that have vested and are no
longer subject to forfeiture according to the Vesting Schedule are referred to
herein as "VESTED UNITS." Restricted Stock Units that have not vested and remain
subject to forfeiture under the Vesting Schedule are referred to herein as
"UNVESTED UNITS." The Unvested Units will vest (and to the extent so vested
cease to be Unvested Units remaining subject to forfeiture) and become payable
in accordance with the Vesting Schedule (the Unvested and Vested Units are
collectively referred to herein as the "UNITS"). As soon as practicable after
Unvested Units become Vested Units, the Company will settle the Vested Units by
issuing to you one share of the Company's Common Stock for each Vested Unit.

2.   TERMINATION OF AWARD UPON TERMINATION OF CONTINUOUS SERVICE

     Unless the Plan Administrator determines otherwise prior to your
termination of Continuous Service, upon your termination of Continuous Service
any portion of the Award that has not vested as provided in Section 1 will
immediately terminate and all Unvested Units shall immediately be forfeited
without payment of any further consideration to you.

3.   SECURITIES LAW COMPLIANCE

     3.1 You represent and warrant that you (a) have been furnished with a copy
of the Plan and all information which you deem necessary to evaluate the merits
and risks of receipt of the Award, (b) have had the opportunity to ask questions
and receive answers concerning the information received about the Award and the
Company, and (c) have been given the opportunity to obtain any additional
information you deem necessary to verify the accuracy of any information
obtained concerning the Award and the Company.

     3.2 You hereby agree that you will in no event sell or distribute all or
any part of the shares of the Company's Common Stock that you receive pursuant
to settlement of this

<PAGE>

Award (the "SHARES") unless (a) there is an effective registration statement
under the Securities Act and applicable state securities laws covering any such
transaction involving the Shares or (b) the Company receives an opinion of your
legal counsel (concurred in by legal counsel for the Company) stating that such
transaction is exempt from registration or the Company otherwise satisfies
itself that such transaction is exempt from registration. You understand that
the Company has no obligation to you to maintain any registration of the Shares
with the SEC and has not represented to you that it will so maintain
registration of the Shares.

     3.3 You confirm that you have been advised, prior to your receipt of the
Shares, that neither the offering of the Shares nor any offering materials have
been reviewed by any administrator under the Securities Act or any other
applicable securities act (the "ACTS") and that the Shares cannot be resold
unless they are registered under the Acts or unless an exemption from such
registration is available.

     3.4 You hereby agree to indemnify the Company and hold it harmless from and
against any loss, claim or liability, including attorneys' fees or legal
expenses, incurred by the Company as a result of any breach by you of, or any
inaccuracy in, any representation, warranty or statement made by you in this
Agreement or the breach by you of any terms or conditions of this Agreement.

4.   TRANSFER RESTRICTIONS

     Units shall not be sold, transferred, assigned, encumbered, pledged or
otherwise disposed of, whether voluntarily or by operation of law.

5.   NO RIGHTS AS STOCKHOLDER

     You shall not have voting or other rights as a stockholder of the Common
Stock with respect to the Units.

6.   INDEPENDENT TAX ADVICE

     You acknowledge that determining the actual tax consequences to you of
receiving or disposing of the Units and Shares may be complicated. These tax
consequences will depend, in part, on your specific situation and may also
depend on the resolution of currently uncertain tax law and other variables not
within the control of the Company. You are aware that you should consult a
competent and independent tax advisor for a full understanding of the specific
tax consequences to you of receiving the Units and receiving or disposing of the
Shares. Prior to executing this Agreement, you either have consulted with a
competent tax advisor independent of the Company to obtain tax advice concerning
the receipt of the Units and the receipt or disposition of the Shares in light
of your specific situation or you have had the opportunity to consult with such
a tax advisor but chose not to do so.

7.   WITHHOLDING

     7.1 You are ultimately responsible for all taxes owned in connection with
this Award, including federal, state, local, FICA or foreign taxes of any kind
required by law, regardless of any action the Company or any Affiliate taxes
with respect to any tax withholding obligations that arise in connection with
this Award.

     7.2 Prior to any event in connection with the Award (e.g., vesting) that
the Company determines may result in any domestic or foreign tax withholding
obligation, whether national, federal, state or local, including FICA or any
other social tax obligation (the "Tax Withholding Obligation"), as a condition
to the settlement of your Vested Units, you agree to make arrangements
satisfactory to the Company for the payment of any Tax Withholding Obligation
that arises either upon receipt of the Shares or as the Unvested Units become
Vested Units.

     7.3 YOUR ACCEPTANCE OF THIS AWARD CONSTITUTES YOUR INSTRUCTION AND
AUTHORIZATION TO THE COMPANY AND ANY BROKERAGE FIRM DETERMINED ACCEPTABLE TO THE
COMPANY FOR SUCH PURPOSE TO SELL ON YOUR BEHALF A WHOLE NUMBER OF SHARES FROM
THOSE SHARES ISSUABLE TO YOU IN PAYMENT OF VESTED UNITS AS THE COMPANY
DETERMINES TO BE APPROPRIATE TO GENERATE CASH PROCEEDS SUFFICIENT TO SATISFY THE
TAX WITHHOLDING OBLIGATION. Such Shares will be sold on the day the Tax
Withholding Obligation arises (e.g., a Vesting Date) or as soon thereafter as
practicable. You will be responsible for all brokerage fees and other costs of
sale, and you agree to indemnify and hold the Company harmless from any losses,
costs, damages, or expenses relating to any such sale. To the extent the
proceeds of such sale exceed your Tax Withholding Obligation, the Company agrees
to pay such excess in cash to you through payroll as soon as practicable. You
acknowledge that the Company or its designee is under no obligation to arrange
for such sale at any particular price, and that the proceeds of any such sale
may not be sufficient to satisfy your Tax Withholding Obligation. Accordingly,
you agree to pay to the Company as soon as practicable, including through
additional payroll withholding, any amount of the Tax Withholding Obligation
that is not satisfied by the sale of Shares described above.

     You acknowledge that this Section 7.3 is intended to comply with the
requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act, and to be
interpreted to comply with the requirements of Rule 10b5-1(c), and that you are
not aware of any material, nonpublic information with respect to the Company or
any securities of the Company as of the date of this Agreement.

     7.4 The Company may refuse to issue any Shares to you until you satisfy the
Tax Withholding Obligation. To the maximum extent permitted by law, the Company
has the right to retain without notice from Shares issuable under the Award or
from salary or other amounts payable to you, Shares or cash having a value
sufficient to satisfy the Tax Withholding Obligation.
