<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant is incorporated under the Wisconsin Business Corporation Law (&#147;WBCL&#148;). Under
Section&nbsp;180.0851(1) of the WBCL, the Registrant is required to indemnify a director or officer, to
the extent such person is successful on the merits or otherwise in the defense of a proceeding, for
all reasonable expenses incurred in the proceeding if such person was a party because he or she was
a director or officer of the Registrant. In all other cases, the Registrant is required by Section
180.0851(2) of the WBCL to indemnify a director or officer against liability incurred in a
proceeding to which such person was a party because he or she was an officer or director of the
Registrant, unless it is determined that he or she breached or failed to perform a duty owed to the
Registrant and the breach or failure to perform constitutes: (i)&nbsp;a willful failure to deal fairly
with the Registrant or its shareholders in connection with a matter in which the director or
officer has a material conflict of interest; (ii)&nbsp;a violation of criminal law, unless the director
or officer had reasonable cause to believe his or her conduct was lawful or no reasonable cause to
believe his or her conduct was unlawful; (iii)&nbsp;a transaction from which the director or officer
derived an improper personal profit; or (iv)&nbsp;willful misconduct. Section&nbsp;180.0858(1) of the WBCL
provides that, subject to certain limitations, the mandatory indemnification provisions do not
preclude any additional right to indemnification or allowance of expenses that a director or
officer may have under the Registrant&#146;s articles of incorporation, bylaws, a written agreement or a
resolution of the Board of Directors or shareholders.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;180.0859 of the WBCL provides that it is the public policy of the State of Wisconsin
to require or permit indemnification, allowance of expenses and insurance to the extent required or
permitted under Sections&nbsp;180.0850 to 180.0858 of the WBCL for any liability incurred in connection
with a proceeding involving a federal or state statute, rule or regulation regulating the offer,
sale or purchase of securities.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;180.0828 of the WBCL provides that, with certain exceptions, a director is not liable
to a corporation, its shareholders, or any person asserting rights on behalf of the corporation or
its shareholders, for damages, settlements, fees, fines, penalties or other monetary liabilities
arising from a breach of, or failure to perform, any duty resulting solely from his or her status
as a director, unless the person asserting liability proves that the breach or failure to perform
constitutes any of the four exceptions to mandatory indemnification under Section&nbsp;180.0851(2)
referred to above.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under Section&nbsp;180.0833 of the WBCL, directors of the Registrant against whom claims are
asserted with respect to the declaration of an improper dividend or other distribution to
shareholders to which they assented are entitled to contribution from other directors who assented
to such distribution and from shareholders who knowingly accepted the improper distribution, as
provided therein.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;VIII of the Registrant&#146;s Bylaws contains provisions that generally parallel the
indemnification provisions of the WBCL and cover certain procedural matters not dealt with in the
WBCL. Directors and officers of the Registrant are also covered by directors&#146; and officers&#146;
liability insurance under which they are insured (subject to certain exceptions and limitations
specified in the policy) against expenses and liabilities arising out of proceedings to which they
are parties by reason of being or having been directors or officers.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy as expressed in
the Act and is, therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred or paid by a
director, officer or controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person in connection with
the securities being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

The Plexus Corp. 2005 Equity Incentive Plan, as amended
(the "2005 Plan") provides for possible adjustment of the number, price and kind of shares covered by options granted or to be granted, and of the number and kind of shares which may be awarded as restricted stock, in the event of certain capital or
other changes affecting the Registrant's Common Stock. This Registration Statement
therefore covers, in addition to the above stated 2,700,000 shares, an indeterminate
number of shares that may become subject to the 2005 Plan by means of any such
adjustment.
(2)
Pursuant to Rule 457(h), estimated solely for the purpose of computing the
registration fee. The offering price is based on options for 727,080 shares, which
were issued pursuant to the 2005 Plan on May 18, 2005 at $12.94 per share, and the
remaining 1,972,920 shares based upon $12.46 per share, which is the average of the
high and low sales prices of the Registrant's Common Stock as reported in the Nasdaq
Stock Market on May 16, 2005. The actual offering price for future awards will be
determined in accordance with the terms of the Plan.
(3)
Under the Plan, the exercise price at which shares may be purchased under each
option, and the base price of any SAR, shall equal the Fair Market Value, as defined,
of the Registrant's Common Stock when the option is granted.
(4)
One right is issued in tandem with each share of Plexus Common Stock. The
value attributable to the Preferred Stock Purchase Rights is reflected in the market
price of the Common Stock to which the Rights are attached. Includes registration of shares of the Registrant's Preferred Stock and Common Stock underlying such rights.

Item 5. Interests of Named Experts and Counsel.
The legality of the shares of Common Stock registered hereunder are being passed on for the
Registrant by Quarles & Brady LLP, the Registrant's legal counsel.
Item 6. Indemnification of Directors and Officers.
The Registrant is incorporated under the Wisconsin Business Corporation Law ("WBCL"). Under
Section 180.0851(1) of the WBCL, the Registrant is required to indemnify a director or officer, to
the extent such person is successful on the merits or otherwise in the defense of a proceeding, for
all reasonable expenses incurred in the proceeding if such person was a party because he or she was
a director or officer of the Registrant. In all other cases, the Registrant is required by Section
180.0851(2) of the WBCL to indemnify a director or officer against liability incurred in a
proceeding to which such person was a party because he or she was an officer or director of the
Registrant, unless it is determined that he or she breached or failed to perform a duty owed to the
Registrant and the breach or failure to perform constitutes: (i) a willful failure to deal fairly
with the Registrant or its shareholders in connection with a matter in which the director or
officer has a material conflict of interest; (ii) a violation of criminal law, unless the director
or officer had reasonable cause to believe his or her conduct was lawful or no reasonable cause to
believe his or her conduct was unlawful; (iii) a transaction from which the director or officer
derived an improper personal profit; or (iv) willful misconduct. Section 180.0858(1) of the WBCL
provides that, subject to certain limitations, the mandatory indemnification provisions do not
preclude any additional right to indemnification or allowance of expenses that a director or
officer may have under the Registrant's articles of incorporation, bylaws, a written agreement or a
resolution of the Board of Directors or shareholders.
Section 180.0859 of the WBCL provides that it is the public policy of the State of Wisconsin
to require or permit indemnification, allowance of expenses and insurance to the extent required or
permitted under Sections 180.0850 to 180.0858 of the WBCL for any liability incurred in connection
with a proceeding involving a federal or state statute, rule or regulation regulating the offer,
sale or purchase of securities.
Section 180.0828 of the WBCL provides that, with certain exceptions, a director is not liable
to a corporation, its shareholders, or any person asserting rights on behalf of the corporation or
its shareholders, for damages, settlements, fees, fines, penalties or other monetary liabilities
arising from a breach of, or failure to perform, any duty resulting solely from his or her status
as a director, unless the person asserting liability proves that the breach or failure to perform
constitutes any of the four exceptions to mandatory indemnification under Section 180.0851(2)
referred to above.
Under Section 180.0833 of the WBCL, directors of the Registrant against whom claims are
asserted with respect to the declaration of an improper dividend or other distribution to
shareholders to which they assented are entitled to contribution from other directors who assented
to such distribution and from shareholders who knowingly accepted the improper distribution, as
provided therein.
Article VIII of the Registrant's Bylaws contains provisions that generally parallel the
indemnification provisions of the WBCL and cover certain procedural matters not dealt with in the
WBCL. Directors and officers of the Registrant are also covered by directors' and officers'
liability insurance under which they are insured (subject to certain exceptions and limitations
specified in the policy) against expenses and liabilities arising out of proceedings to which they
are parties by reason of being or having been directors or officers.

Item 7. Exemption From Registration Claimed.
Not applicable.
Item 8. Exhibits.
See Exhibit Index following the signatures page in this Registration Statement, which Exhibit
Index is incorporated herein by reference.
Item 9. Undertakings.
(a) The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement:
(i)
To include any prospectus required by Section
10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or
events arising after the effective date of the Registration Statement
(or the most recent post-effective amendment thereof) which,
individually or in the aggregate, represent a fundamental change in the
information set forth in the Registration Statement. Notwithstanding
the foregoing, any increase or decrease in volume of securities offered
(if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20%
change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective Registration
Statement;
(iii)
To include any material information with
respect to the plan of distribution not previously disclosed in the
Registration Statement or any material change to such information in
the Registration Statement;
Provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if
the Registration Statement is on Form S-3 or Form S-8, and the information required to be included
in a post-effective amendment by those paragraphs is contained in periodic reports filed by the
Registrant with the Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the Registration Statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.
(b) The undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant
to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by
reference in the
- 4 -
Table of Contents
Registration Statement shall be deemed to be a new registration statement relating
to the securities offered
therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
(h) Reference is made to the indemnification provisions described in Item 6 of this
Registration Statement.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the Registrant pursuant to the
foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy as expressed in
the Act and is, therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred or paid by a
director, officer or controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person in connection with
the securities being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
