                    INFORMATION REQUIRED IN THE REGISTRATION

                                    STATEMENT

Item 3.  Incorporation of Documents by Reference.

     The following documents filed by F5 Networks, Inc. (the "Company") with the
Securities and Exchange Commission are incorporated by reference into this
Registration Statement:

     (a)  Annual Report on Form 10-K for the year ended September 30, 2001;

     (b)  Quarterly Report on Form 10-Q for the quarter ended December 31, 2001,
          and

     (c)  the description of the Company's common stock contained in the
          Company's Registration Statement Form 8-A, filed May 11, 1999 under
          the Securities Exchange Act of 1934, as amended (the "Exchange Act")
          including any amendments or reports filed for the purposes of updating
          such description.

     All documents subsequently filed by the Company pursuant to Sections 13(a),
13(c), 14 or 15(d) of the Exchange Act, prior to the filing of a post-effective
amendment which indicates that all securities offered have been sold or which
deregisters all securities then remaining unsold, shall be deemed to be
incorporated by reference herein and to be part hereof from the date of filing
of such documents.

Item 4. Description of Securities.

     Not Applicable

Item 5. Interests of Named Experts and Counsel.

     Not Applicable

Item 6. Indemnification of Directors and Officers.

     Sections 23B.08.500 through 23.B.08.600 of the Washington Business
Corporation Act (the "WBCA") authorize a court to award, or a corporation's
board of directors to grant, indemnification to directors and officers on terms
sufficiently broad to permit indemnification under certain circumstances for
liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Section 23B.08.320 of the WBCA authorizes a corporation to
limit a director's liability to the corporation or its shareholders for monetary
damages for acts or omissions as a director, except in certain circumstances
involving intentional misconduct, knowing violations of law or illegal corporate
loans or distributions, or any transaction from which the director personally
receives a benefit in money, property or services to which the director is not
legally entitled.

     The Company's Second Amended and Restated Articles of Incorporation and
Amended and Restated Bylaws contain provisions permitting the Company to
indemnify its directors and officers to the full extent permitted by Washington
law. In addition, the Company's Second Amended and Restated Articles of
Incorporation contain a provision implementing, to the fullest extent permitted
by Washington law, the above limitations on a director's liability to the
Company and its shareholders. The Company has entered into certain
indemnification agreements with its directors and certain of its officers, the
form of which is attached as Exhibit 10.1 to its Registration Statement on Form
S-1 (File No. 333-75817). The indemnification agreements provide the Company's
directors and certain of its officers with indemnification to the maximum extent
permitted by the WBCA. The directors and officers of the Company also may be
indemnified against liability they may incur for serving in that capacity
pursuant to a liability insurance policy maintained by the Company for this
purpose.

                                Statement).


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;

     (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) do not apply if
the information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant


                                       3


pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in this 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
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.

     (c) 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
Securities Act of 1933 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 of whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
