The Registrant hereby incorporates by reference into this Registration Statement the following documents previously filed with the Securities
and Exchange Commission (the "
Commission
"):
(1) The Registrant's Annual Report on Form 10-K (File
No. 001-35957) for the fiscal year ended December 28, 2013, filed with the Commission on March 13, 2014 pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the "

that information therein is furnished and not filed with the Commission; and
(3) The description of the Registrant's common stock
contained in the Company's Registration Statement on Form 8-A (File No. 001-35957) filed with the Commission on June 6, 2013, pursuant to Section 12(b) of the Exchange Act, including any amendment or report filed for the purpose
of updating such description.
All documents filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange
Act on or after the date of this Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement that indicates that all securities offered have been sold or that deregisters all securities then remaining

provided
,
however
, that documents or information deemed to have been furnished and
not filed
in accordance with the rules of the Commission shall not be deemed incorporated by reference into this Registration Statement. Any statement contained in a document incorporated or deemed to be

Item 4. Description of Securities.
Not applicable.
Item 5. Interests
of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
The Registrant's amended and restated certificate of incorporation contains provisions that eliminate, to the maximum extent permitted by
the General Corporation Law of the State of Delaware, the personal liability of the Registrant's directors and executive officers for monetary damages for breach of their fiduciary duties as directors or officers. The Registrant's amended
and restated certificate of incorporation and bylaws provide that the Registrant must indemnify its directors and executive officers and may indemnify its employees and other agents to the fullest extent permitted by the General Corporation Law of
the State of Delaware.
Sections 145 and 102(b)(7) of the General Corporation Law of the State of Delaware provide that a corporation may
indemnify any person made a party to an action by reason of the fact that he or she was a director, executive officer, employee or agent of the corporation or is or was serving at the request of a corporation against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not
opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of an action by or in right of the corporation, no
indemnification may generally be made in respect of any claim as to which such person is adjudged to be liable to the corporation.
The
Registrant has entered into indemnification agreements with its directors and executive officers, in addition to the indemnification provided for in its amended and restated certificate of incorporation and bylaws, and intends to enter into
indemnification agreements with any new directors and executive officers in the future.
The Registrant has purchased and intends to
maintain insurance on behalf of each and any person who is or was a director or officer of the Registrant against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain
exclusions.
See also the undertakings set out in response to Item 9 herein.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
See Exhibit Index immediately following the Signature Pages.
Item 9. Undertakings.
A.
The undersigned Registrant hereby undertakes that:
(1)
It will 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;
(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; and
(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 with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in
this Registration Statement.
(2)
For the purpose of determining any liability under the Securities 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.
(3)
It will 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, each filing of the Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) 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 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 Commission such indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe
that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Santa Clara, State of California, on the 13th day
of March, 2014.
