<DIV align="left" style="font-size: 10pt; margin-top: 12pt">Item&nbsp;6. Indemnification of Directors and Officers.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;102(b)(7) of the Delaware General Corporation Law (the &#147;DGCL&#148;) allows a corporation to
eliminate the personal liability of directors of a corporation to the corporation or to any of its
stockholders for monetary damage for a breach of his or her fiduciary duty as a director, except in
the case where the director breached his or her duty of loyalty, failed to act in good faith,
engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend
or approved a stock repurchase in violation of the DGCL or obtained an improper personal benefit.
The Company&#146;s Amended and Restated Certificate of Incorporation contains a provision that
eliminates directors&#146; personal liability as set forth above.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under Section&nbsp;145 of the DGCL, the Company has broad powers to indemnify its directors and
officers against liabilities they may incur in such capacities, including liabilities under the
Securities Act. The Company&#146;s Certificate of Incorporation and By-laws require the Company to
indemnify its directors and officers to the full extent permitted by the DGCL. The Certificate of
Incorporation and By-laws also require the Company to advance litigation expenses upon receipt of
an undertaking by the indemnified party to repay such advances if it is ultimately determined that
the indemnified party is not entitled to indemnification.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company has entered into indemnity agreements with each of its directors and executive
officers. Such indemnity agreements contain provisions that are in some respects broader than the
specific indemnification provisions contained in the DGCL. The Company also maintains an insurance
policy for its directors and officers insuring against certain liabilities arising in their
capacities as such.

directors, officers and controlling persons of the registrant pursuant to the foregoing provisions,

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.

This registration statement on Form S-8 is (i) a new registration statement and (ii) a
Post-Effective Amendment No. 1 to each of the registrant's registration statements on Form S-8
(registration nos. 333-93423, 333-38078, 333-57486, 333-84904, 333-104108, 333-113651, 333-123323,
333-132478) (collectively, the "Prior Registration Statements").
(1)
The shares of the registrant's common stock being registered under this registration
statement consists of: (i) 6,037,824 shares of common stock that remained available for
issuance under the registrant's 1997 Stock Option Plan (the "Prior Plan") as of April 3, 2006
and which are being carried forward to this registration statement for issuance under
registrant's 2006 Equity Incentive Plan (the "2006 Plan") and (ii) up to 5,000,000 shares of
common stock subject to outstanding stock options under the Prior Plan that terminate, expire
or are canceled without having been exercised and which will be carried forward to this
registration statement for issuance under the 2006 Plan upon such termination, expiration or
cancellation. The shares being carried forward to this registration statement for issuance
under the 2006 Plan (the "Carried Forward Shares") have previously been registered pursuant to
the Prior Registration Statements. In addition, pursuant to Rule 416(a) under the Securities
Act of 1933, as amended (the "Securities Act"), this registration statement shall also cover
any additional shares of the registrant's common stock that become issuable under the 2006
Plan by reason of any stock dividend, stock split, recapitalization or other similar
transaction effected without the registrant's receipt of consideration that results in an
increase in the number of the registrant's outstanding shares of common stock.
(2)
The Carried Forward Shares were previously registered pursuant to the Prior Registration
Statements. In accordance with Interpretation 89 under Section G, "Securities Act Forms" of
the Manual of Publicly Available Telephone Interpretations of the Division of Corporations
Finance and the Securities and Exchange Commission (as supplemented), the registration fees
allocable to the Carried Forward Shares and previously paid by the registrant pursuant to the
Prior Registration Statements are being carried forward to this registration statement. Thus,
no registration fee is required. A post-effective amendment to each of the Prior Registration
Statements is filed herewith to reflect the reallocation of the Carried Forward Shares and the
associated registration fees from the Prior Registration Statements to this registration
statement.

EXPLANATORY NOTE

under Section G, "Securities Act Forms" of the Manual of Publicly Available Telephone
Interpretations of the Division of Corporations Finance and the Securities and Exchange Commission
(as supplemented), Maxygen, Inc. (the "Company") is hereby filing a new registration statement and
a Post-Effective Amendment No. 1 to each of the Company's registration statements on Form S-8
(registration nos. 333-93423, 333-38078, 333-57486, 333-84904, 333-104108, 333-113651, 333-123323,
333-132478) (collectively, the "Prior Registration Statements") to reflect that (i) up to
11,037,824 shares of the Company's common stock previously registered pursuant to the Prior
Registration Statements for issuance under the Company's 1997 Stock Option Plan (the "Prior Plan")
are being carried forward to this registration statement (the "Carried Forward Shares") for
issuance under the Company's 2006 Equity Incentive Plan (the "2006 Plan") and (ii) the registration
fees allocable to the Carried Forward Shares and previously paid by the Company pursuant to the
Prior Registration Statements are being carried forward to this registration statement.

available for issuance under the Prior Plan as of April 3, 2006 and which are being carried forward
and reserved for issuance under the 2006 Plan and (ii) up to 5,000,000 shares of common stock
subject to outstanding stock options under the Prior Plan that terminate, expire or are canceled
without having been exercised and which will be carried forward and reserved for issuance under the
2006 Plan upon such termination, expiration or cancellation. The 2006 Plan was adopted by the
Company's Board of Directors on February 7, 2006, subject to stockholder approval, and was approved

Item 6. Indemnification of Directors and Officers.
Section 102(b)(7) of the Delaware General Corporation Law (the "DGCL") allows a corporation to
eliminate the personal liability of directors of a corporation to the corporation or to any of its
stockholders for monetary damage for a breach of his or her fiduciary duty as a director, except in
the case where the director breached his or her duty of loyalty, failed to act in good faith,
engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend
or approved a stock repurchase in violation of the DGCL or obtained an improper personal benefit.
The Company's Amended and Restated Certificate of Incorporation contains a provision that
eliminates directors' personal liability as set forth above.
Under Section 145 of the DGCL, the Company has broad powers to indemnify its directors and
officers against liabilities they may incur in such capacities, including liabilities under the
Securities Act. The Company's Certificate of Incorporation and By-laws require the Company to
indemnify its directors and officers to the full extent permitted by the DGCL. The Certificate of
Incorporation and By-laws also require the Company to advance litigation expenses upon receipt of
an undertaking by the indemnified party to repay such advances if it is ultimately determined that
the indemnified party is not entitled to indemnification.
The Company has entered into indemnity agreements with each of its directors and executive
officers. Such indemnity agreements contain provisions that are in some respects broader than the
specific indemnification provisions contained in the DGCL. The Company also maintains an insurance
policy for its directors and officers insuring against certain liabilities arising in their
capacities as such.
Item 7. Exemption from Registration Claimed.

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;
(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
Securities Exchange Act of 1934 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 therein, 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 that remain unsold at the termination of the offering.
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 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.
