                                                                  EXECUTION COPY

                    AMENDMENT NO. 1, CONSENT, WAIVER AND AGREEMENT dated as of
               August 19, 2005 (this "AMENDMENT"), to the Credit Agreement dated
               as of April 1, 2005 (the "CREDIT AGREEMENT"), among AMI
               SEMICONDUCTOR, INC., a Delaware corporation (the "BORROWER"),
               AMIS HOLDINGS, INC., a Delaware corporation ("HOLDINGS"), the
               Lenders (as defined in Article I of the Credit Agreement) and
               CREDIT SUISSE (formerly known as Credit Suisse First Boston), as
               administrative agent (in such capacity, the "ADMINISTRATIVE
               AGENT") and as collateral agent (in such capacity, the
               "COLLATERAL AGENT" ) for the Lenders.

     A. Pursuant to the Credit Agreement, the Lenders have extended, and have
agreed to extend, credit to the Borrower.

     B. Holdings and the Borrower have informed the Administrative Agent that
Holdings and the Borrower, including through one or more existing or newly
formed Wholly Owned Subsidiaries that are Foreign Subsidiaries (each a
"TRANSACTION SUBSIDIARY"), intend to acquire (the "ACQUISITION") from
Flextronics Semiconductor, Inc., a corporation organized under the laws of
Delaware, and certain of its affiliates (collectively, the "SELLERS"), the
assets comprising the mixed signal, peripheral imaging components and digital
businesses of the Sellers (the "ACQUIRED BUSINESS"), pursuant to one or more
asset purchase agreements (as the same may be amended from time to time on or
prior to the Supplemental Term Loan Closing Date (as defined below), the
"PURCHASE AGREEMENTS") among the Borrower, certain affiliates of the Borrower
and the Sellers, for aggregate cash consideration of approximately $135,000,000
(subject to adjustment in accordance with the Purchase Agreements, the
"ACQUISITION CONSIDERATION").

     C. In connection with the foregoing, Holdings and the Borrower have
requested that (i) senior secured supplemental term loans (the "SUPPLEMENTAL
TERM LOANS") be made to the Borrower by certain financial institutions (the
"SUPPLEMENTAL TERM LENDERS") in an aggregate principal amount of $110,000,000,
the proceeds of which will be used to finance in part the Acquisition and to pay
related fees and expenses and the terms of which shall be identical to the
existing Term Loans outstanding under the Credit Agreement, and (ii) the
Required Lenders (a) consent to the Acquisition, (b) waive compliance by
Holdings and the Borrower with certain provisions of the Credit Agreement in
connection therewith and (c) agree to waive and amend certain provisions of the
Credit Agreement as provided herein.

     D. Holdings and the Borrower have further informed the Administrative Agent
that, following the consummation of the Acquisition, Holdings and the Borrower,
including through one or more Wholly Owned Subsidiaries, propose to sell the
"System on a Chip" business acquired pursuant to the Acquisition (the "SOC
SALE"). Holdings and the Borrower anticipate that the SOC Sale will generate Net
Cash Proceeds of up to $10,000,000.

     E. Holdings and the Borrower have also informed the Administrative Agent
that AMI Acquisition II LLC, a Wholly Owned Subsidiary of the Borrower ("AMI
ACQUISITION II"), proposes to merge with and into the Borrower (the "PROPOSED
MERGER"). AMI Acquisition II and the Borrower each holds a 5% general membership
interest in Emma Mixed Signal C.V. ("EMMA") and AMI Acquisition LLC, another
Wholly Owned Subsidiary of the Borrower ("AMI

                                                                               2


ACQUISITION"), holds a 90% limited membership interest in Emma. Following the
consummation of the Proposed Merger, the Borrower will hold a 10% general
membership interest in Emma, and modifications will be made to Emma's
constitutive documents (or shareholders' agreements relating thereto) such that
AMI Acquisition will hold 90% of the voting interests in Emma and the Borrower
will hold 10% of the voting interests in Emma (the "VOTING INTEREST
REALIGNMENT").

     F. The Supplemental Term Lenders are willing to make the Supplemental Term
Loans and the Required Lenders are willing to grant such consents and waivers
and to agree to such amendments, in each case on the terms and subject to the
conditions set forth herein.

     G. Capitalized terms used but not defined herein shall have the meanings
assigned to them in the Credit Agreement.

     Accordingly, in consideration of the mutual agreements herein contained and
other good and valuable consideration, the sufficiency and receipt of which are
hereby acknowledged, the parties hereto agree as follows:

     SECTION 1. SUPPLEMENTAL TERM LOANS. (a) Subject to the terms and conditions
set forth herein and relying upon the representations and warranties set forth
herein and in the other Loan Documents, each Supplemental Term Lender agrees,
severally and not jointly, to make a Supplemental Term Loan to the Borrower on
the Supplemental Term Loan Closing Date in a principal amount not to exceed the
commitment of such Supplemental Term Lender to make Supplemental Term Loans as
set forth on Schedule I hereto.

     (b) The Borrower will use the proceeds of the Supplemental Term Loans only
for the purposes specified in the recitals to this Amendment.

     (c) Unless the context shall otherwise require, the terms "TERM LOANS" and
"LOANS" as used in the Credit Agreement shall include the Supplemental Term
Loans, and the terms "TERM LENDERS" and "LENDERS" as used herein and in the
Credit Agreement shall include each Supplemental Term Lender (other than any
Supplemental Term Lender that has ceased to be a party to the Credit Agreement
pursuant to an Assignment and Acceptance).

     SECTION 2. CONSENT AND WAIVER. (a) The Required Lenders hereby consent to
the Acquisition on substantially the terms described above, and hereby waive
compliance by Holdings and the Borrower with the provisions of Sections 6.01,

Acquisition between or amongst themselves and (ii) to capitalize the Transaction
Subsidiaries and any intermediate Wholly Owned Subsidiary holding company,
including by way of intercompany loans evidenced by one or more promissory notes
pledged to the Collateral Agent for the ratable benefit of the Secured Parties
to the extent required by the Loan Documents, for purposes of the foregoing.

     (b) The Required Lenders hereby consent to the SOC Sale, and hereby waive
compliance by Holdings and the Borrower with the provisions of Section 6.05 of

     (f) The Required Lenders hereby consent to the Collateral Agent and the
relevant Loan Parties entering into amendments, restatements or supplements to
the Foreign Pledge Agreements to the extent (but only to the extent) necessary
to secure the Supplemental Term Loans as additional obligations thereunder and
permit the Voting Interest Realignment and the other transactions contemplated
hereby.

     SECTION 3. AMENDMENTS. (a) The definition of the term "Consolidated
Operating Income" set forth in Section 1.01 of the Credit Agreement is hereby
amended by inserting the phrase "or Flextronics Acquisition Transaction Costs"
at the end of clause (f) therein.
