EXHIBIT 10.4(b)

Change in Control Agreement
This AGREEMENT (the “Agreement”) is made as of the Effective Date by and between
Plexus Corp., a Wisconsin corporation (the “Company”) and the Employee.
Recital:
The Board of Directors (the “Board”) of the Company has determined that it is in
the best interests of the Company and its shareholders to reinforce and
encourage the Employee’s continued attention and dedication to the Employee’s
assigned duties without distraction by entering into compensation arrangements
that will provide financial security in the event of a Change in Control.
Now, therefore, it is hereby agreed as follows:
1.
Defined Terms. Capitalized terms not otherwise defined in the main body of this
Agreement have the meaning ascribed thereto in Schedule A and Exhibit 1.

2.
Change in Control. No benefits shall be payable under this Agreement unless
there shall have been a Change in Control.

3.
Term of Agreement. This Agreement shall be effective for the period commencing
on the Effective Date and ending on the Initial Term Date; provided, however,
that:

3.1.     On an annual basis the term of this Agreement shall automatically be
extended for an additional fiscal
year unless, not later than 30 days before the Agreement would otherwise expire,
the Company shall
have given notice that it does not wish to extend this Agreement; and
3.2.    Notwithstanding any such notice by the Company, if a Change in Control
shall have occurred during
the original or any extended term of this Agreement, this Agreement shall remain
in effect until the
Company shall have performed all its obligations hereunder.
4.
Qualifying and Nonqualifying Separations. For purposes of this Agreement:

4.1.    A “Qualifying Separation” means the Employee’s Separation from Service
during the Change in
Control Period by reason of (i) the Company’s termination of the Employee’s
employment other than
for Cause, or (ii) the Employee’s resignation for Good Reason; provided,
however, that a Qualifying
Separation shall not include a Separation from Service by reason of the
Employee’s death or Disability.
4.2.    A “Nonqualifying Separation” means a Separation from Service during the
Change in Control Period,
other than a Qualifying Separation.
5.
Company’s Obligations Upon a Qualifying Separation. In the event of the
Employee’s Qualifying Separation:

5.1.    Accrued Obligations. The Company shall pay to the Employee the Accrued
Obligations in cash within
30 days after the Separation Date.
5.2.    Lump-Sum Payment. The Company shall pay to the Employee in cash within
30 days after the
Separation Date (except as otherwise provided by Section 7) the sum of the
following amounts:
(a)
The Employee’s Target Bonus, prorated through the Separation Date using a
fraction, the numerator of which is the number of days in the Separation Year
through the Separation Date, and the denominator of which is 365;

(b)
The Separation Multiplier times the sum of the Employee’s Annual Base Salary,
the Target Bonus, and the Retirement Differential; and

(c)
An amount such that, after payment of all Federal, state, and local income taxes
on such amount (deemed for this purpose to be payable at the applicable
withholding rates), the Employee retains the amount that the Company determines
is equal to the value of continued participation (on the same basis), for a
number of years equal to the Separation Multiplier, in all group health and
other welfare plans and the Company’s executive reimbursement plan, company car,
and other similar plans and arrangements in which the Employee participated

--------------------------------------------------------------------------------

immediately before the Separation Date or in which the Employee participated
immediately before the Change in Control Date, whichever produces the greater
benefit.
5.3.    Outplacement. The Company shall at its sole expense provide the Employee
with executive-level
outplacement services, the scope and provider of which shall be selected by the
Company in its sole
discretion, for a period of 15 months beginning on the Separation Date.
5.4.    Other Benefits. To the extent not theretofore paid or provided, and
without duplication of any other
benefits hereunder, the Company shall timely pay or provide to the Employee such
other amounts or
benefits as are required to be paid or provided, or that the Employee is
eligible to receive, under any
written plan, program, policy or contract or agreement of Plexus (collectively,
“Other Benefits”).
5.5.    Code Section 280G. Notwithstanding any provision of this Agreement to
the contrary, in the event
that you become entitled to receive payments or benefits under this Agreement or
under any other
plan, agreement or arrangement with the Company (all such payments and benefits
being referred
to herein as the “Total Payments”) and it is determined that any of the Total
Payments will be
subject to any excise tax pursuant to Code Section 4999, or any similar or
successor provision (the
“Excise Tax”), the Company shall pay you either (i) the full amount of the Total
Payments or (ii) an
amount equal to the Total Payments, reduced by the minimum amount necessary to
prevent any
portion of the Total Payments from being an “excess parachute payment” (within
the meaning of
Code Section 280G) (the “Capped Payments”), whichever of the foregoing amounts
results in the
receipt by you, on an after-tax basis, of the greatest amount of Total Payments
notwithstanding that
all or some portion of the Total Payments may be subject to the Excise Tax.
5.6.    No Duplication of Benefits. Notwithstanding Section 5.4, this Agreement
supersedes and terminates
the Employee’s right to any severance benefits otherwise due to the Employee
upon a Qualifying
Termination under any other plan or policy of the Company or any written
employment agreement
between the Employee and the Company.
6.
Company’s Obligations Upon a Nonqualifying Separation. In the event of the
Employee’s Nonqualifying Separation:

6.1.    Accrued Obligations. The Company shall pay to the Employee the Accrued
Obligations in cash within
30 days after the Separation Date.
6.2    Other Benefits. The Company shall timely pay or provide to the Employee
the Other Benefits.
7.
Six-Month Suspension. If the Company determines that the Employee is a Specified
Employee as of the Separation Date, then any payment required by Sections 5.2,
5.4 and 6.2 shall be made on the Company’s first regular payroll date (the
“Six-Month Date”) on or after the six-month anniversary of the Separation Date,
and any payment required by Section 5.5 shall be made on the later of the
Six-Month Date or the date such payment would be made without regard to this
Section 7.

8.
Governing Law.

8.1.    This Agreement shall be governed by and construed in accordance with the
laws of the State of
Wisconsin, without reference to principles of conflict of laws.
8.2.    The jurisdiction and venue for any disputes arising under, or any action
brought to enforce, or otherwise
relating to, the Agreement shall be exclusively in the courts in the State of
Wisconsin, including the
Federal Courts located therein or responsible therefore (should Federal
jurisdiction exist).
9.
Miscellaneous

Additional terms of this Agreement are set forth in Schedule B.
IN WITNESS WHEREOF, the Employee has hereunto set the Employee’s hand and,
pursuant to the authorization from its Board of Directors, the Company has
caused these presents to be executed in its name on its behalf, all as of the
Effective Date.

incapacity due to physical or mental illness), after a written demand for
substantial performance is delivered to the Employee by the Board, the Chief
Executive Officer of the Company, or the President of the Company that
specifically identifies the manner in which the Board, the Chief Executive
Officer, or the President believes that the Employee has not substantially
performed the Employee’s duties, and after the Employee has been given at least
30 days in which to cure such failure; or

(b)
The willful engaging by the Employee in illegal conduct or gross misconduct that
is materially and demonstrably injurious to the Company. For purposes of this

considered “willful” unless it is done, or omitted to be done, by the Employee
in bad faith or without reasonable belief that the Employee’s action or omission
was in the best interests of the Company. Any act, or failure to act, based upon
authority given pursuant to a resolution duly adopted by the Board or upon the
instructions of the Chief Executive Officer or a senior officer of the Company
or based upon the advice of counsel for the Company shall be conclusively
presumed to be done, or omitted to be done, by the Employee in good faith and in
the best interests of the Company.

The cessation of employment of the Employee shall not be deemed to be for Cause
unless and until there shall have been delivered to the Employee a copy of a
resolution duly adopted by the affirmative vote of not less than three-quarters
of the entire membership of the Board at a meeting of the Board called and held
for such purpose (after reasonable notice is provided to the Employee and the
Employee is given an opportunity, together with counsel, to be heard before the
Board), finding that, in the good faith opinion of the Board, the Employee is
guilty of the conduct described in paragraph (a) or (b) above, and specifying

corporation that enters into a merger, consolidation, purchase, or acquisition
of stock, or similar business transaction with the Company, but not including
persons or groups solely because they purchase stock of the Company at the same
time or as a result of the same public offering), acquires (or has acquired
within the 12-month period ending on the date of the most recent acquisition by
such person or group) securities of the Company representing 30 percent or more
of the combined voting power of the Company’s then outstanding securities;

--------------------------------------------------------------------------------

(b)

time or as a result of the same public offering), acquires ownership of stock of
the Company that, together with stock held by such person or group, constitutes

but only if such person or group did not own more than 50 percent of the
combined voting power of the stock of the Company prior to such acquisition; or

(d)
any person, or more than one person acting as a group (including owners of a
corporation that enters into a merger, consolidation, purchase or acquisition of
assets, or similar business transaction with the Company, but not including
persons or groups solely because they purchase assets of the Company at the same
time), acquires (or has acquired during the 12-month period ending on the date
of the most recent acquisition by such person or group) assets from the Company
that have a total gross fair market value of more than 50 percent of the total
gross fair market value of all of the assets of the Company immediately before
such acquisition or acquisitions, except where the assets are transferred to (i)
a shareholder of the Company (immediately before the asset transfer) in exchange
for or with respect to its stock, (ii) an entity, 50 percent or more of the
total value or voting power of which is owned, directly or indirectly, by the
Company, (iii) a person, or more than one person acting as a group, that owns,
directly or indirectly, 50 percent or more of the total value or voting power of
all outstanding stock of the Company, or (iv) an entity, at least 50 percent of
the total value or voting power of which is owned, directly or indirectly, by a
person or group described in (iii) above.

Notwithstanding the foregoing, unless a majority of the incumbent Board
determines otherwise, no Change in Control shall be deemed to have occurred with

in which he is a participant in a capacity other than solely as an officer,
employee or member of the Board.

at the request of a third party who has taken steps reasonably calculated to
effect a Change in Control, or (y) otherwise arose in connection with or

include the period beginning on the date immediately prior to the date of such

Control.

(a)
the assignment to the Employee of any duties inconsistent in any respect with
the Employee’s position (including status, offices, titles and reporting
requirements), authority, duties or responsibilities immediately prior to the
Change in Control Date, or any other action by the Company which results in a
diminution in such position, authority, duties or responsibilities, excluding
for this purpose an isolated,

--------------------------------------------------------------------------------

insubstantial and inadvertent action not taken in bad faith and which is
remedied by the Company promptly after receipt of notice thereof given by the
Employee;

incentive compensation) with a value no less than the value of the last
stock-based award received by the Employee immediately before the Change in
Control Date;

(c)
the Company’s requiring the Employee to be based at any office or location that
is 45 miles or more from the office or location where the Employee is based

required immediately prior to the Change in Control Date; or

(d)
any failure by the Company to comply with and satisfy Section C.1(c) of Schedule
