                  SUPPLEMENTAL CONTINGENT SHARE AWARD AGREEMENT

      This SUPPLEMENTAL CONTINGENT SHARE AWARD AGREEMENT (the "AGREEMENT"),
dated August 17, 2004, is entered into by and between Michael E. Marks
("EXECUTIVE") and Flextronics International USA, Inc. (the "COMPANY").

      WHEREAS, Executive is currently employed by the Company as its Chief
Executive Officer; and

      WHEREAS, Executive has provided service to the Company for over ten years;
and

      WHEREAS, the Company has previously granted a Contingent Stock Award to
Executive on May 18, 2004 (the "INITIAL DEFERRED COMPENSATION CONTINGENT STOCK
AWARD"); and

      WHEREAS, the Company and Executive desire to enter into an agreement to
supplement the Initial Deferred Compensation Contingent Stock Award upon the
achievement of certain Company share performance targets (the "SUPPLEMENTAL
DEFERRED COMPENSATION CONTINGENT STOCK AWARD").

      NOW, THEREFORE, in consideration of the mutual promises made herein, the
Company and Executive hereby agree as follows:

      1. GRANT OF CONTINGENT STOCK AWARD. Subject to all of the terms of this
Agreement, the Company hereby grants to Executive a Supplemental Deferred
Compensation Contingent Stock Award for 500,000 Ordinary Shares at an exercise
price equal to $11.00 per share ($0.06 above the closing price of the Ordinary
Shares on the Nasdaq Stock Market on August 17, 2004 (the "EXERCISE PRICE").
This Supplemental Deferred Compensation Contingent Stock Award shall entitle the
Account of the Executive to be credited with Deferred Compensation as set forth
in Section 2 below; provided that in no event shall the aggregate amount
evaluation under this Supplemental Deferred Compensation Contingent Stock Award
and the Initial Deferred Compensation Contingent Stock Award require the Company
to make credits to the Executive's Account in excess of $7,500,000 (the "TOTAL
AWARD AMOUNT").

      2. CREDITING OF AWARD AMOUNT. Within two (2) business days following the
relevant Measurement Date, the Company will credit Executive's Account with
Deferred Compensation in an amount equal to (a)(i) the excess of the Average
Share Price as of such Measurement Date over the Exercise Price, multiplied by
(ii) 500,000, less (b) the amounts credited to the Executive's Account as
Deferred Compensation under (x) the Initial Deferred Compensation Contingent
Stock Award on or prior to the relevant Measurement Date and (y) under this
Supplemental Deferred Compensation Contingent Stock Award prior to the relevant
Measurement Date (the "CURRENT OR PRIOR CREDITS"). Credits to the Executive's
Account under this Section 2 will continue until the earlier of (a) the date on
which the Total Award Amount has been credited to the Executive's Account or (b)
the termination date of Executive's employment with the Company and/or any
subsidiary of the Company. All amounts credited to Executive's Account shall be
fully vested and nonforfeitable.

<PAGE>

      3. ACCELERATION OF PAYMENT. Notwithstanding the foregoing, in the event of
(a) Executive's death or Disability or (b) a Change of Control, then the Company
shall immediately credit Executive's Account with an amount equal to the Total
Award Amount less the sum of all Current or Prior Credits. All amounts credited
to Executive's Account shall be fully vested and nonforfeitable.

      4. CONDITIONS TO PAYMENT OF AWARD AMOUNT. Unless otherwise set forth in
Sections 2 or 3, Executive must be employed by the Company on the applicable
Measurement Date in order to be credited with an Award Amount, if any, for the
Measurement Date.

      5. ADJUSTMENTS TO ORDINARY SHARES. In the event that the number of
outstanding shares of the Ordinary Shares is changed by a stock dividend,
recapitalization, stock split, reverse stock split, subdivision, combination,
reclassification, or similar change in the capital structure of the Company
without consideration, then the number and kind of shares subject to this
Supplemental Contingent Stock Award and the Exercise Price will be
proportionately adjusted, subject to any required action by the Board or the
stockholders of the Company and compliance with applicable securities law.

SECTION 2.2 PURCHASE PRICE AND PAYMENT PROCEDURES

      Section 2.3(2) is hereby amended by inserting the following new
sub-section immediately after Section 2.3(2):

"2.3(2)(a). A portion of each twenty-five million dollar ($25,000,000) Cash Flow
Payment payable pursuant to Schedule 2.3.2, at the Closing of the Design
Operations conducted by the Canada Design Employees at the Ottawa Lab 2/Lab 10
Facility and by the UK Design Employees at the Monkstown Facility, is intended
to represent an advance of the portions of the two hundred million dollars
($200,000,000) referenced in Section 2.3(1) that represent part of the Purchase
Price with respect to the other Facilities. Notwithstanding the foregoing:

(i) in the event that the Closing for the Montreal BAN 1 Facility, the Montreal
BAN 3 Facility and the Montreal OPTO 1 Facility (collectively, the "MONTREAL
FACILITIES") shall not have occurred on or before February 1, 2005, then (a)
Purchaser shall not be required to pay the instalment of twelve million five
hundred thousand dollars ($12,500,000) otherwise payable on such date pursuant
to Section 2.3(3) until the earlier of (I) the Closing for the Montreal
Facilities, and (II) September 1, 2005, and (b) Seller shall not be required to
pay any Transition Payment instalments otherwise payable on such date pursuant
to Section 5.18, until the earlier of (I) the Closing for the Montreal
Facilities, and (II) September 1, 2005 (which September 1, 2005, payments shall
each be subject to Section 2.3(2)(c));

(ii) in the event that (a) the Closing for the Montreal Facilities shall not
have occurred on or before May 1, 2005, and (b) the Closing for the Calgary
Westwinds Facility shall not have occurred on or before May 1, 2005, then (I)
Purchaser shall not be required to pay the instalment of twelve million five
hundred thousand dollars ($12,500,000) otherwise payable on such date pursuant
to Section 2.3(3) until the earlier of (A) the Closings for the Calgary
Westwinds Facility, and (B) September 1, 2005, and (II) Seller shall not be
required to pay any Transition Payment instalments otherwise payable on such
date pursuant to Section 5.18, until the earlier of (A) the Closing for the
Calgary Westwinds Facility, and (B) September 1, 2005 (which September 1, 2005,
payments shall each be subject to Section 2.3(2)(c)); and

(iii) in the event that the Closing for the Monkstown Facility or the Calgary
Westwinds Facility shall not have occurred on or before September 1, 2005, then
the amount payable by the Purchaser to the Seller on that date shall be reduced
by the portion thereof, if any, that represented an advance of a portion of the
Purchase Price for such Facility/Facilities. The Parties further agree that the
amount payable by the Seller to the Purchaser on that date as a Transition
Payment shall be reduced by the same percentage as the reduction in the amount
payable by the Purchaser to the Seller referred to above in this paragraph.

2.3(2)(b). If the Closing for the Montreal Facilities does not occur on or
before March 1, 2005, the Parties shall within ten (10) days of such date meet
to negotiate in good faith the portion of Design Operations Cash Flow Payment
that represented the amount of the fifty million dollars ($50,000,000) allocable
to the first Closing (Design Operations). If the Parties are not able to reach
agreement on such amount within twenty five (25) days of March 1, 2005 ("DROP
DEAD DATE"), then, notwithstanding anything to the contrary in this Agreement,
the Parties shall negotiate the Settlement Transaction (as defined below).

2.3(2)(c). (i) If the Drop Dead Date shall have passed without agreement as set
forth in Section 2.3 (2)(b), the Parties shall within two (2) Business Days of
such date commence the repurchase by the Seller of the Design Operations
transferred in the first Closing and to terminate the Agreement with respect to
the other Facilities, with such termination to be effective as of the closing
date of the Settlement Transaction but otherwise in accordance with the terms of
the Agreement.

(ii) From the commencement of the negotiations, Purchaser shall maintain the
Assets and operate the Design Operations in the ordinary course for the benefit
of Seller.

(iii) The Parties agree to negotiate terms of the repurchase ("SETTLEMENT
TRANSACTION") such that they shall ensure the economic effect as of sixty (60)
days after the commencement of the Settlement Transaction negotiations, and that
the Settlement Transaction shall include the following terms:

(a) At the Settlement Transaction, (I) Seller shall pay to Purchaser the sum of
seven million eight hundred and three thousand one hundred and forty six dollars
($7,803,146), less applicable depreciation on the Assets transferred for the
period November 1, 2004 to May 1, 2005 (the "SETTLEMENT PURCHASE PRICE"), and
shall waive its right, if any, to receive any deferred portions of such Cash
Flow Payments, and (II) Purchaser shall waive its right, if any, to receive any
deferred portions of any Transition Payments that have not already been paid
(but shall be entitled to retain those Transition Payments that were paid on
November 1, 2004), and neither Party shall be entitled to compensation for any
Losses that it has or may have incurred prior to such negotiations commencing.
By way of illustration, Purchaser shall not be entitled to recoup any Losses it
may have incurred associated with running such Design Operations and Seller
shall not be entitled to be reimbursed for failure of the Design Operations to
provide services in accordance with the terms of the Amended and Restated Master
Contract Manufacturing Services Agreement and the exhibits thereto, in each case
during the time period prior to commencement of the Settlement Transaction
negotiations; provided, however, that the foregoing shall not act as a waiver of
Purchaser's rights to be paid any amounts which are due for services previously
provided to the Seller under the Amended and Restated Master Contract
Manufacturing Services Agreement and the exhibits thereto but for which

Execution Copy

                                     - 4 -
<PAGE>

either invoices have yet not been issued or such invoices have been issued but
payment has not yet been made.

(b) the Purchaser shall make the same representation and warranties to Seller as
Seller made to Purchaser in the Agreement to the extent applicable under the
circumstances.

(c) all Transfer Taxes payable from the Settlement Transaction shall be paid by
the Parties in accordance with the principles set forth for payment by the
purchaser and seller, as the case may be, in Section 5.6 of the Agreement,
mutatis mutandis.

(d) the first Closing (Design Operations) Assets shall be transferred to Seller,
at Purchaser's cost, in the same condition as originally transferred by Seller,
reasonable wear and tear excepted; provided, however, that if Purchaser is
unable to return any Assets to Seller, or such Assets are physically damaged,
reasonable wear and tear excepted (the "NON TRANSFERRED ASSETS"), the Settlement
Purchase Price, less applicable depreciation on the Assets transferred for the
period November 1, 2004 to May 1, 2005.

(e) The Amended and Restated Master Contract Manufacturing Services Agreement
and the other Transaction Documents (other than the Confidentiality Agreement)
shall be terminated, effective as of the closing date of the Settlement
Transaction, in accordance with their respective terms.

(f) Purchaser shall promptly inform and consult with the employees'
representative of the UK Design Employees, and Seller shall cooperate with
Purchaser in such process. With respect to any assets or employees in the UK,
the Settlement Transaction shall constitute only an irrevocable binding offer by
Seller to effect the transaction contemplated, which offer shall be deemed
accepted, automatically and without further action on the part of any Person,
upon due completion of such consultation process. With respect to the employees
in Canada, Seller shall make offers of employment with terms and conditions
which are substantially similar in the aggregate to the employees then-current
terms and conditions; any transfer or offer of employment will, to the extent
applicable, follow substantially the same processes as were followed in the
transfer of employment from Seller to Purchaser.

(g) Subject to any limitations under applicable Law, Seller shall be permitted
to solicit any of the UK Design Employees or Canada Design Employees who became
Transferring Employees and remain employed by Purchaser or one of its Affiliates
at the time of the Settlement Transaction. Subject to any limitations under
applicable Law, Purchaser and its Affiliates shall provide reasonable assistance
to Seller with such solicitation efforts.

(h) the Parties shall cooperate fully with one another to facilitate a smooth
transition of the Design Operations, in order to allow Seller to fully assume
and continue such Design Operations without material interruption in the
services provided by the Purchaser pursuant to the Amended and Restated
Manufacturing Services Agreement.

(i) Purchaser and Seller shall take such additional actions and perform such
additional tasks as may be reasonably necessary to ensure a timely transfer of
the Design Operations to Seller."
