by the Registrant against, in the case of a non-derivative action, judgments,
fines, amounts paid in settlement and reasonable expenses&#160; (including attorneys&#146; fees) incurred by him

expenses (including attorneys&#146; fees), if in either type of action he acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Registrant. This indemnification does not apply, in a
derivative action, to matters as to which it is adjudged that the director,

the indemnification provisions summarized in Item 6 or otherwise, the
Registrant has been advised that, in the opinion of the Commission, such
indemnification is against public policy as expressed in the 1933 Act, and is,
therefore, unenforceable.&#160; 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 1933 Act and will be governed by the final adjudication of
such issue.</p>

reason of any stock dividend, stock split, recapitalization or other similar

Calculated solely for
purposes of this offering under Rule 457(h) of the Securities Act of 1933, as

selling price per share of Registrant's Common Stock on February 10, 2005

The Employee Stock Purchase Plan establishes a purchase price equal to
85% of the fair market value of the Registrant's Common Stock and, therefore,
the price for this plan  is based on 85%
of the average of the high and low selling prices per share of the Registrant's
Common Stock on February 10, 2005 as reported by the Nasdaq National
Market.

Incorporation of
Documents by Reference
Silicon Laboratories Inc.
(the "Registrant") hereby incorporates by reference into this Registration
Statement the following documents previously filed with the Securities and
Exchange Commission (the "Commission"):
(a)
The
Registrant's Annual Report on Form 10-K containing audited financial statements
for the fiscal year ended January 1, 2005, filed with the Commission on February 15,
2005;
(b)
All
other reports filed pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934, as amended (the "1934 Act") since the end of the fiscal
year covered by the Registrant's Annual Report referred to in (a) above; and
(c)
The
Registrant's Registration Statement No. 000-29823 on Form 8-A filed with the
Commission on March 7, 2000 pursuant to Section 12 of the 1934 Act, in
which there is described the terms, rights and provisions applicable to the
Registrant's outstanding Common Stock.
All reports and
definitive proxy or information statements filed pursuant to Section 13(a),
13(c), 14 or 15(d) of the 1934 Act after the date of this Registration
Statement and prior to the filing of a post-effective amendment which indicates
that all securities offered hereby have been sold or which de-registers all
securities then remaining unsold shall be deemed to be incorporated by reference
into this Registration Statement and to be a part hereof from the date of
filing of such documents.  Unless
expressly incorporated into this Registration Statement, a report furnished on
Form 8-K shall not be incorporated by reference into this Registration
Statement.  Any statement contained in a

Item 5.
Interests of Named
Experts and Counsel
Not applicable.
Item 6.
Indemnification of
Directors and Officers
Section 145 of the Delaware General
Corporation Law (the "DGCL") provides, in effect, that any person made a party
to any action by reason of the fact that he is or was a director, officer,
employee or agent of the Registrant may and, in some cases, must be indemnified
by the Registrant against, in the case of a non-derivative action, judgments,
fines, amounts paid in settlement and reasonable expenses  (including attorneys' fees) incurred by him
as a result of such action, and in the case of a derivative action, against
expenses (including attorneys' fees), if in either type of action he acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Registrant. This indemnification does not apply, in a
derivative action, to matters as to which it is adjudged that the director,
officer, employee or agent is liable to the Registrant, unless upon court order
it is determined that, despite such adjudication of liability, but in view of
all the circumstances of the case, he is fairly and reasonably entitled to indemnity
for expenses, and, in a non-derivative action, to any criminal proceeding in
which such person had no reasonable cause to believe his conduct was unlawful.
The Registrant's certificate of incorporation
provides that no director shall be liable to the Registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by the
II
-1
DGCL.  The Registrant's bylaws
require it to indemnify its directors and executive officers to the fullest
extent permitted by Delaware law. The Registrant has entered into
indemnification agreements with all of its directors and executive officers and
has purchased directors' and officers' liability insurance.
Reference is made to the underwriting
agreement filed as Exhibit 1.1 to Registrant's Registration Statement No.
333-94853, pursuant to which the underwriters have agreed to indemnify the
Registrant's officers and directors against certain liabilities under the
Securities Act.

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 Act,
as amended (the "1933 Act"), (ii) to reflect in the prospectus any facts or
events arising after the effective date of this 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 this
Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii)
shall not apply if the information required to be included in a post-effective
amendment by those clauses is contained in periodic reports filed with or
furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d)
of the 1934 Act that are incorporated by reference into this Registration
Statement; (2) that for the purpose of determining any liability under the 1933
Act 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; and (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 Registrant's 2000 Stock Incentive Plan, as amended and
restated March 8, 2001, and Employee Stock Purchase Plan.
B.
The
undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the 1933 Act, each filing of the Registrant's annual report
pursuant to Section 13(a) or Section 15(d) of the 1934 Act that is
incorporated by reference into this 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.
II
-2
C.
Insofar
as indemnification for liabilities arising under the 1933 Act may be permitted
to directors, officers, or controlling persons of the Registrant pursuant to
the indemnification provisions summarized in Item 6 or otherwise, the
Registrant has been advised that, in the opinion of the Commission, such
indemnification is against public policy as expressed in the 1933 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 1933 Act and will be governed by the final adjudication of
such issue.
