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 Company’s amended and restated certificate of incorporation provides that the Company must indemnify the Company’s directors to the fullest extent under applicable law. Pursuant to Delaware law, this includes elimination of liability for monetary damages for breach of the directors’ fiduciary duty of care to the Company and its stockholders. However, directors of the Company may be personally liable for liability:
for any breach of duty of loyalty to the Company or to its stockholders;
for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
for unlawful payment of dividends or unlawful stock repurchases or redemptions under Section 174 of the Delaware General Corporation Law; or
for any transaction from which the director derived an improper personal benefit.
In addition, the Company’s amended and restated bylaws provide that:
the Company is required to indemnify directors and executive officers of the Company to the fullest extent not prohibited by Delaware law or any other applicable law, subject to limited exceptions;
the Company may indemnify other officers, employees and other agents of the Company as set forth in Delaware law;
the Company is required to advance expenses to directors and executive officers of the Company as incurred in connection with legal proceedings against them for which they may be indemnified; and
the rights conferred in the amended and restated bylaws are not exclusive.
The Company has also provided for liability insurance for each director and officer for certain losses arising from claims or charges made against them while acting in their capacities as directors or officers of the Company.
The Company has entered into indemnification agreements with each of the directors and certain officers of the Company. These agreements, among other things, require the Company to indemnify each director and officer to the fullest extent permitted by Delaware law, including indemnification for expenses such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or officer in any action or proceeding, including any action by or in the right of the Company, arising out of the person’s services as a director or officer of the Company, any subsidiary of the Company or any other company or enterprise to which the person provides services at the Company’s request. At present, the Company is not aware of any pending or threatened litigation or proceeding involving any of the directors, officers, employees or

4



agents of the Company in which indemnification would be required or permitted. The Company believes that the charter provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.
ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED
Not applicable.

ITEM 9. UNDERTAKINGS
1.
The undersigned registrant hereby undertakes:
(a)
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;
(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

6



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)(i) and (a)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in 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 the registration statement.
(b)
That, 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)
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.
(d)
That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
(i)
Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)
Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii)
The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv)
Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
2.
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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
3.
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 Securities and Exchange 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.

Alameda, CA 94502
Re:    Post-Effective Amendment to Registration on Form S-8
Ladies and Gentlemen:
We have acted as counsel to Exelixis, Inc., a Delaware corporation (the “Company”), and you have requested our opinion in connection with the filing with the Securities and Exchange Commission (the “Commission”) of:
(a) Post-Effective Amendment No. 1 to the Registrant’s registration statements on Form S-8 (File Nos. 333-214766, 333-212866, 333-209824 and 333-203758), as filed with the Commission on November 22, 2016, August 3, 2016, February 29, 2016, and April 30, 2015, respectively;
(b) Post-Effective Amendment No. 2 to the Registrant’s registration statements on Form S-8 (File Nos. 333-196761 and 333-176674), as originally filed with the Commission on June 13, 2014, and September 2, 2011, respectively; and
(c) Post-Effective Amendment No. 3 to the Registrant’s registration statements on Form S-8 (File Nos. 333-165389, 333-157825, 333-149834, 333-147063, 333-133237, 333-124536, 333-113472, 333-102770, 333-82722, 333-57026 and 333-35862), as originally filed with the Commission on March 10, 2010, March 10, 2009, March 20, 2008, October 31, 2007, April 12, 2006, May 2, 2005, March 10, 2004, January 28, 2003, February 14, 2002, March 14, 2001, and April 28, 2000, respectively (the registration statements set forth in (a), (b) and (c) above, collectively, the “Prior Registration Statements,” and these post-effective amendments to the Prior Registration Statements, collectively, the “Post-Effective Amendments”).
The Prior Registration Statements covered the offering of shares of the Company’s Common Stock, $0.001 par value (“Common Stock”), previously available for issuance under the Company’s 2014 Equity Incentive Plan, 2011 Equity Incentive Plan, 2000 Equity Incentive Plan, as amended and restated, 2000 Non-Employee Directors’ Stock Option Plan and 2016 Inducement Award Plan (collectively, the “Prior Plans”). For purposes of this opinion, the “Shares” means up to 21,115,472 shares of Common Stock subject to outstanding stock awards granted under the Prior Plans that from and after July 27, 2018 may become available for grant under the Company’s 2017 Equity Incentive Plan (the “2017 Plan”) as described in the Post-Effective Amendments.
In connection with this opinion, we have examined and relied upon the Prior Registration Statements, the Post-Effective Amendments and the related Prospectus, the Company’s Amended and Restated Certificate of Incorporation and Bylaws, as currently in effect, the Prior Plans, the 2017 Plan and the originals or copies certified to our satisfaction of such other records, documents, certificates, memoranda and other instruments as we deem necessary or appropriate to enable us to render the opinion expressed below.
