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. </FONT></P>

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, 2012;
(b) Quarterly Reports on Form 10-Q for the quarters ended December 31,
2012, March 31, 2013, and June 30, 2013;
(c) all other reports filed by the Registrant pursuant to
Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), since the end of the fiscal year covered by the Annual Report on Form 10-K referred to in paragraph (a) above (excluding any
documents or portions of such documents that are furnished under Item 2.02 or Item 7.01 of a current report on Form 8-K and any exhibits included with such Items); and
(d) the description of the Company's common stock contained in the Company's Registration Statement on 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 (excluding any
documents or portions of such documents that are furnished under Item 2.02 or Item 7.01 of a current report on Form 8-K and any exhibits included with such Items), 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.08.603 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 Third Amended and Restated Articles of Incorporation, as amended, and Third 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 Third Amended and Restated Articles of Incorporation, as amended, 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.
Item 7. Exemption from Registration Claimed.
Not Applicable.

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 percent 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)
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 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.
