AMENDMENT NO. 3 TO LICENSE AGREEMENT




     This Amendment No. 3 (“Amendment No. 3”) amends that certain License Agreement effective March
28, 2002 entered by and between Maxygen, Inc. (“MUS”) and Codexis, Inc. (“Codexis”), as previously
amended by Amendment No. 1 to License Agreement effective September 13, 2002, and Amendment No. 2
to License Agreement effective October 1, 2002, (as amended, the “Agreement”), and shall be
effective as of August 22, 2006 (the “Third Amendment Date”). MUS and Codexis hereby amend the
Agreement as follows:




	1.	 	Article 1 is amended by the addition of the following new definitions:






     1.60 “Consumer Price Index” or “CPI” means the Consumer Price Index, All Urban
Consumers, as published by the U.S. Bureau of Labor Statistics




     1.61 “Energy Product” means any (i) Supplemental Product subject to any Modified
SubField, and (ii) Scheduled Product subject to 1 of Exhibit F of the Agreement.




     1.62 “FTE” means the efforts of one or more employees of Codexis equivalent to the
efforts of one Codexis full time employee (i.e., an employee that works at least one thousand seven hundred sixty (1760)
hours per year.




     1.63 “Net Sales” shall mean means the consideration received by Codexis or its
Affiliates for the sale or use of Energy Products in arm’s length sales to an independent
Third Party, after deduction of the following items, provided and to the extent such items
are actually incurred and documented and do not exceed reasonable and customary amounts in
the market in which such sale occurred: (i) ordinary and customary trade discounts actually
allowed; (ii) credits, rebates and returns; (iii) freight, insurance and duties paid for and
separately identified on the invoice or other documentation maintained in the ordinary
course of business, and (iv) taxes, duties and other compulsory payments to governmental
authorities actually paid and separately identified on the invoice or other documentation
maintained in the ordinary course of business. All sales or use of Energy Products between
Codexis and any of its Affiliates shall be disregarded for purposes of computing Net Sales.
A “sale” shall include any transfer or other disposition for consideration, and Net Sales
shall include all consideration received by Codexis or its Affiliates in respect of any sale
or use of Energy Products, whether such consideration is in cash, payment in kind, exchange
or another form.






 









 











In the case of discounts on “bundles” of products and/or services which include Energy
Products, Codexis may with notice to MUS calculate the Net Sales by discounting the bona
fide list price of an Energy Product by no more than the average percentage discount of all
products and services of Codexis and/or its Affiliates in a particular “bundle”, calculated
as follows:



	 	 	 	 	 	 	 
	 

	 	Average percentage	 	 	 	 
	 

	 	discount on a
	 	=
	 	(1 — A/B) x 100
	 

	 	particular “bundle"	 	 	 	 







where A equals the total discounted price of a particular “bundle” of products and services,
and B equals the sum of the undiscounted bona fide list prices of each unit of every product
and service in such “bundle”. Codexis shall provide MUS documentation, reasonably
acceptable to MUS, establishing such average discount with respect to each “bundle”. If
Codexis cannot so establish the average discount of a bundle, the Net Sales shall be based
on the undiscounted list price of the Energy Product in the bundle. If an Energy Product in
a bundle is not sold separately and no bona fide list price exists for such Energy Product,
the Parties shall negotiate in good faith an imputed list price for such Energy Product, and
Net Sales with respect thereto shall be based on such imputed list price.




	2.	 	The following definitions in Article 1 shall be amended to read as follows:






     1.55 “Reserved SubField Termination Date” shall mean (a) for SubFields 1, 2, 4, 5, 6
and 7, the period commencing on the Amendment Date and ending on the later of (i) five (5)
years after Amendment Date, or (ii) a Separation Event, and (b) for SubFields 3, 8, 9 and 10
(the “Modified SubFields”), the period commencing on the Amendment Date and ending six (6)
years after the Amendment Date; provided, however, that in the event Codexis has satisfied
the criteria set forth in Section 2.1.6(a) as to a particular SubField within the Modified
SubFields such that such entire SubField becomes included in the Codexis Field, as provided
in Section 2.1.6(d), on or before six (6) years after the Amendment Date, then the Reserved
SubField Termination Date shall be extended by one additional year; and further provided
that upon the satisfaction of the criteria set forth in Section 2.1.6(d) for each additional
SubField within the Modified SubFields, if any, the Reserved SubField Termination Date for
the remaining Modified SubFields shall be extended for an additional one (1) year period, up
to a maximum of three (3) such additional one (1) year extensions.




     1.56 “Reserved SubFields” shall mean, in the period from the Amendment Date until the
applicable Reserved SubField Termination Date, the subject matter within the applicable
SubField(s). It is understood and agreed that as of the applicable Reserved SubField
Termination Date, (a) one or more Categories within the Reserved SubFields may become part
of the Codexis Field pursuant to Section 2.1.6(c), (b), one or more of the Reserved
SubFields may become part of the Codexis Field pursuant to Section 2.1.6(d), and (c) any
Category and any Reserved SubField that is not within the scope of the Codexis Field
pursuant to subsection (a) or (b) above as of the applicable Reserved



2









 






SubField Termination Date, shall be terminated, and shall no longer be within the
Reserved SubFields.




     1.57 “Scheduled Product” shall mean any Product described on Exhibit F.




     1.59 “Supplemental Product” shall mean any Biocatlyst or Enzyme Product, and/or
chemical made with the use of a Biocatlyst or Enzyme Product, in each case, that is (a)
within a Category, where Codexis conducts with regard to such Category a research project

Termination Date, and (b) within a Reserved SubField that becomes part of the Codexis Field
at any time prior to the applicable Reserved SubField Termination Date pursuant to Section
2.1.6(d).”




	3.	 	Section 2.1.1 is amended as follows:






a. In the first clause, revise the phrase “. . . worldwide, royalty-free (subject to Section
2.1.5(b) licenses, . . .” to read: “. . . worldwide, royalty-free (subject to Section
2.1.5(b) and the terms of Article 5) licenses, . . .”




b. Revise Sections 2.1.1(a)(i), 2.1.1(a)(ii), 2.1.1(d)(i) and 2.1.1(d)(ii) by adding the
phrase “and/or Section 2.1.6(d)” after each occurrence of the phrase “pursuant to Section
2.1.6(c)”.




c. Revise Section 2.1.1 by changing each occurrence of “the Reserved SubField Termination
Date” to “the applicable Reserved SubField Termination Date”.




	4.	 	Section 2.1.6 is amended as follows:

forth in Section 2.1.6(c), and (ii) any Reserved SubField for which Codexis has satisfied
the criteria set forth in Section 2.1.6(d), it is understood and agreed that as of the
applicable Reserved SubField Termination Date, the applicable Reserved SubFields (including
each Category and SubField) shall be terminated and shall have no content or force or effect
for the remainder of the term of the Agreement, and, as of the applicable Reserved SubField
Termination Date, MUS (and/or its designee) shall have, as between the Parties, the
exclusive rights in and to and shall be free, at its sole discretion, to work in, such
Reserved SubField(s) without restriction or obligation to Codexis.”




	6.	 	Article 5 shall be revised to read in its entirety as follows:

     5.1 Codexis Stock. In partial consideration for the rights granted hereunder,
Codexis shall issue to MUS one million (1,000,000) shares of Common Stock and six million
(6,000,000) shares of Series A Preferred Stock of Codexis pursuant to the Stock Issuance and
Asset Contribution Agreement by and between MUS and Codexis of even date hereof.




     5.2 Energy Products. In consideration for the rights granted to Codexis in
this Amendment No. 3, for all Energy Products and/or any grant of rights with regard to the
use of any Enabling Technology for the development and commercialization of any Energy
Product, Codexis will pay MUS:




          5.2.1 [****] of all consideration received by Codexis from any Sublicensee or Third
Party for:




               a. option and/or license fees for rights to use any Enabling Technology to develop
and/or make any Energy Product; and




               b. development payments (e.g., milestone payments) in respect of any Energy Product,
and/or any product made with the use of any Energy Product; and




               c. royalties and/or other payments for the commercialization of any Energy Product,
and/or any product made with the use of any such Energy Product; and




               d. the purchase of any equity securities of Codexis; provided, that the consideration
received by Codexis from such Sublicensee or Third Party in connection with such purchase
shall be deemed to be the amount obtained by multiplying [****]; provided that at the time
of such purchase such Sublicensee or Third Party has a contractual relationship with Codexis
(or proposes to have a contractual relationship with Codexis in connection with such
purchase and the contractual relationship thereafter becomes effective), and the primary
business purpose of the relationship is the development and/or commercialization of (i) any
Energy Product, or (ii) any product made with the use of any Energy Product; and




          5.2.2 Notwithstanding anything to the contrary in Section 5.2.1 above, Codexis shall
not be required to pay to MUS any share of research and/or development funding received (and
not subject to any further performance criteria) by Codexis from a Third Party for the
support of Codexis personnel (i.e., payments on an FTE basis to support Codexis employees
for activities conducted by Codexis); provided that (i) such payments are actually used by
Codexis for FTE funding, and (ii) the applicable rate per





 




			
	*	 	Certain information on this page has been omitted and filed
separately with the Securities and Exchange Commission. Confidential treatment
has been requested with respect to the omitted portions.

FTE does not exceed the Base FTE Rate. The Base FTE Rate for 2006 shall be [****] per
FTE per year, and shall be revised annually at the beginning of each subsequent calendar
year to reflect annual changes in the Consumer Price Index, using September 2006 as the
baseline comparison. Codexis shall pay to MUS [****] of any research funding received from a
Third Party for the development of any Energy Product, and/or any product made with the use
of any Energy Product, in each case only to the extent such funding does not satisfy the
criteria listed in subsections (i) and (ii) above.




          5.2.3 If Codexis directly commercializes any Energy Product, Codexis will pay to MUS a
royalty of [****] of (a) Net Sales of such Energy Products sold by Codexis or its
Affiliates, and/or (b) amounts received by Codexis or its Affiliates from any Sublicensee or
other Third Party for the use of Energy Products, to the extent Codexis or its Affiliates
utilize such Product(s) to provide services to such Sublicensee or Third Party, as the case
may be.




     5.3 Quarterly Reports. Commencing in the first calendar quarter in which
Codexis receives any payment subject to Section 5.2, Codexis shall make quarterly written
reports to MUS within sixty (60) days after the end of each calendar quarter, stating in
each such report the consideration subject to Section 5.2 received by it during such
calendar quarter. Such reports shall provide separately for Codexis and each of its
Affiliates and Sublicensees, in each case, on a country-by-country and Energy
Product-by-Energy Product basis:




	 	(i)	 	the type (e.g., license fee, milestone payment)
and amount of consideration received;
	 
	 	(ii)	 	for payments based on Energy Products, the
quantity and description of each such Energy Product sold or used; and
	 
	 	(iii)	 	the calculation of amounts due to MUS,
accompanied by sufficient information to enable MUS to verify the
accuracy of the calculations made by Codexis, and a detailed
explanation of the methodology used to determine the applicable
payment.






     5.4 Payment. Concurrently with providing to MUS each quarterly report
described in Section 5.3, Codexis shall pay MUS all amounts due under Section 5.2 for the
calendar quarter corresponding to such report.




     5.5 Audit. Codexis and its Affiliates shall keep complete, true and accurate
books of account and records for the purpose of determining the amounts payable under
Section 5.2 of this Agreement. Such books and records shall be kept at the principal place
of business of such party, as the case may be, for at least four (4) years following the end
of the calendar quarter to which they pertain. Such records will be open for inspection
during such four (4) year period by a public accounting firm selected by MUS reasonably
acceptable to Codexis, solely for the purpose of verifying the reports and

payments hereunder. Such inspections may be made no more than once each calendar year,
at reasonable times and on reasonable notice. Inspections conducted under this Section 5.5
shall be at the expense of MUS, unless a variation or error producing an increase exceeding
ten percent (10%) of the amount stated for any period covered by the inspection is
established in the course of any such inspection, whereupon all reasonable costs relating to
the inspection and any unpaid amounts that are discovered will be paid promptly by Codexis
together with interest thereon as set forth in Section 5.6 below.




     5.6 Payment Method; Late Payments. All payments due to MUS under this
Agreement shall be paid in U.S. dollars by bank wire transfer in immediately available funds
to a bank account designated by MUS. Any payment or portion thereof that is not paid on the
date such payments are due under this Agreement shall bear interest at the lesser of (i) the
prime rate as reported by the Chase Manhattan Bank, New York, New York (or its successor) on
the date such payment is due, plus an additional two percent (2%), or (ii) the maximum rate
permitted by law, in each case calculated on the number of days such payment is delinquent.
This Section 5.6 shall in no way limit any other remedies available for late payment.




     5.7 Currency Conversion. All payments due to MUS under this Agreement shall
first be determined in local currency and then, if necessary, converted to its equivalent in
United States currency. The buying rates of exchange for converting the currencies involved
into the currency of the United States quoted by the Wall Street Journal (or its
successor in interest) on the last business day of the quarterly period in which the
payments were received by Codexis shall be used to determine any such conversion.




     5.8 Restrictions on Payment. The obligation of Codexis to pay amounts to MUS
under this Agreement with respect to sales of Energy Products in a particular country shall
be waived and excused to the extent that statutes, laws, codes or government regulations in
a particular country prevent such payments; provided, however, in such event, if legally
permissible, Codexis shall pay the amounts owed to MUS by depositing such amounts in a bank
account in such country that has been designated by MUS and promptly report such payment to
MUS in writing.




     5.9 Taxes. Any tax that Codexis is required to withhold and pay on behalf of
MUS with respect to amounts payable to MUS under this Agreement shall be deducted from and
offset against said payments prior to remittance to MUS; provided, however, that in regard
to any tax so deducted, Codexis shall give or cause to be given to MUS such assistance as
may reasonably be necessary to enable MUS to claim exemption therefrom or credit therefor,
and in each case shall furnish MUS with proper evidence of the taxes paid on its behalf.




     5.10 Energy Affiliate.




          (a) If (i) Codexis or any of its Affiliates or subsidiaries (each, a “Codexis Entity")
proposes to form, establish or acquire, directly or indirectly, any Affiliate or subsidiary
that engages in a line of business related to the use of any Energy



6









 






Products, and/or any Enabling Technology in or for any energy application (the “Energy
Rights"), or any Affiliate or subsidiary of Codexis proposes, at any time, to engage,
directly or indirectly, in such line of business (in each case, an “Energy Affiliate"); (ii)
a Codexis Entity proposes to acquire or obtain, directly or indirectly, by merger,
consolidation, acquisition of equity interests or otherwise, any assets, rights or other
interests of whatever kind and nature in any business or Third Party (e.g. any individual,
corporation, partnership, limited liability company, joint venture or other business
organization or division thereof) that engages in a line of business related to the use of
any of the Energy Rights (or at any time in the future proposes to engage in such line of
business); or (iii) a Codexis Entity proposes to acquire or obtain, directly or indirectly,
by merger, consolidation, acquisition of equity interests or otherwise, or becomes entitled
to, any assets, rights or other interests of whatever kind and nature in any business or
Third Party, in whole or partial consideration for the sale, assignment, license,
contribution, pledge or other transfer by a Codexis Entity of any assets, interests or
rights relating to any of the Energy Rights, then Codexis shall give written notice to MUS
at least thirty (30) days prior to the effectiveness or consummation of such event or
transaction. The notice shall describe in reasonable detail the proposed event or
transaction including, without limitation, the nature of such event or transaction, the
consideration to be paid and the amount constituting the applicable MUS Interest (as defined
in Section 5.10(b) below).




          (b) In consideration for the rights granted to Codexis in this Amendment No. 3, Codexis
shall take, or cause to be taken, all actions, and do, or cause to be done, all things
necessary, proper and advisable under applicable laws, so as to assign, transfer and deliver
the MUS Interest to MUS immediately upon the effectiveness or consummation of any event or
transaction described in Section 5.10(a) above or cause the MUS Interest to be so assigned,
transferred and delivered, without cost to MUS. For purposes of this Section 5.10, the term
“MUS Interest” shall mean all legal and beneficial title to the equity interests, assets,
rights or other interests of whatever kind and nature (other than consideration received by
Codexis subject to Codexis’ payment obligations to MUS pursuant to Section 5.2.1 above) of
the Energy Affiliate or Third Party in an amount equal to [****] of each asset, interest or
right held, acquired or obtained by the Codexis Entity(ies) in connection with any event,
transaction or series of transactions described in Section 5.10(a) above.




          (c) If, in connection with the transaction or series of transactions described in
Section 5.10(a), a Codexis Entity has provided consideration other than assets, interests or
rights relating to the use of any of the Energy Rights (the “Other Consideration”), then, as
a condition of the transfer to MUS of the portion of the MUS Interest held, acquired or
obtained by the Codexis Entity specifically for such Other Consideration, MUS shall
reimburse the Codexis Entity for up to [****] of the cash value of the Other Consideration
(as of the date of transfer of the Other Consideration by the Codexis Entity). The election
to reimburse the Codexis Entity and the amount of such





 




			
	*	 	Certain information on this page has been omitted and filed
separately with the Securities and Exchange Commission. Confidential treatment
has been requested with respect to the omitted portions.




7









 











reimbursement (up to the aforementioned [****] limit) shall be determined by MUS in its
sole discretion. Upon reimbursement, the Codexis Entity shall transfer to MUS the
applicable portion of the MUS Interest attributable to the amount reimbursed by MUS for the
Other Consideration. If MUS elects to reimburse the Codexis Entity for a portion of the
Other Consideration corresponding to the MUS Interest equal to less than [****] of such
Other Consideration, and not for the total [****], MUS’ right to receive additional equity
interests, assets, rights or other interests of whatever kind and nature of the applicable
Energy Affiliate or Third Party pursuant to Section 5.10(b) that are directly attributable
to the equity interests, assets, rights or other interests held, acquired or obtained for
such Other Consideration will be prorated accordingly. For example, if MUS elects to
reimburse the Codexis Entity for [****] of the Other Consideration corresponding to the MUS
Interest (and not [****]), MUS’ right to receive additional equity interests, assets, rights
or other interests of whatever kind and nature of the applicable Energy Affiliate or Third
Party pursuant to Section 5.10(b) that are directly attributable to the equity interests,
assets, rights or other interests held, acquired or obtained for such Other Consideration
will be equal to [****] of the amount that MUS would have received if MUS had reimbursed the
Codexis Entity for [****] of the Other Consideration corresponding to the MUS Interest. If
MUS elects not to pay any amount to the Codexis Entity for the reimbursement of the Other
Consideration, MUS’ right to receive additional equity interests, assets, rights or other
interests of whatever kind and nature of the applicable Energy Affiliate or Third Party
pursuant to Section 5.10(b) that are directly attributable to the equity interests, assets,
rights or other interests held, acquired or obtained for such Other Consideration shall
terminate. Except as otherwise provided in this Section 5.10(c) with respect to an election
by MUS to reimburse the applicable Codexis Entity for Other Consideration, MUS shall, in all
cases, be entitled to receive, and shall not be required to reimburse any Codexis Entity,
Energy Affiliate or Third Party or otherwise pay any amounts to any Codexis Entity, Energy
Affiliate or Third Party for, the MUS Interest and any additional equity interests, assets,
rights or other interests of the applicable Energy Affiliate or Third Party that are
attributable to or received in consideration for any of the Energy Rights (and not
attributable to or received in consideration for Other Consideration).




          (d) If any Codexis Entity proposes to subsequently sell, assign, or otherwise transfer
any assets, rights or interests acquired or obtained in connection with an event,
transaction or series of transactions described in Section 5.10(a) above, then Codexis shall
give written notice to MUS at least thirty (30) days prior to the effectiveness or
consummation of such transaction, which notice shall describe the proposed transaction in
reasonable detail, including, without limitation, the nature of such transaction and the
consideration to be received. MUS shall have the right, exercisable upon written notice to
Codexis within fifteen (15) days after receipt of such notice, to participate in such
transaction and to sell, assign or otherwise transfer up to a pro rata portion of the MUS
Interest on the same terms and conditions as described in the notice; provided, however,
that in no event shall MUS be required to sell, assign or transfer any





 




			
	*	 	Certain information on this page has been omitted and filed
separately with the Securities and Exchange Commission. Confidential treatment
has been requested with respect to the omitted portions.




8









 











portion of the MUS Interest to any party, except as required by applicable law;
provided, further, that MUS’ pro rata portion of the MUS Interest shall be deemed to be
[****] of each asset, right or interest proposed to be sold, assigned or transferred by the
applicable Codexis Entity(ies).




          (e) Notwithstanding the foregoing, if for any reason all or any portion of the MUS
Interest is not transferable to MUS in accordance with Section 5.10(b) above, or if the
sale, assignment or other transfer by MUS of all or any portion of the MUS Interest in
accordance with Section 5.10(d) above is not permitted, then the applicable Codexis
Entity(ies) shall not consummate or effectuate, directly or indirectly, such event or
transaction without the prior written consent of MUS in its sole discretion.




          (f) In the event that (i) sufficient information does not exist to determine the value,
amount or allocation of any assets, rights or interests for purposes of calculating the
applicable MUS Interest, the applicable Other Consideration or any other amount in
accordance with this Section 5.10, or (ii) Codexis and MUS cannot otherwise agree as to such
value, amount or allocation, such value, amount or allocation shall be determined through an
appraisal to be performed by an independent Third Party reasonably acceptable to both
Parties, and the expenses incurred in obtaining such appraisal shall be shared equally by
Codexis and MUS.




          (g) In furtherance of the foregoing, Codexis acknowledges that, in consideration for
the rights granted to Codexis in this Amendment No. 3, this Section 5.10 is intended to
provide MUS with the applicable portion of any value or potential value attributable to or
derived from any business related to energy applications engaged in by any Codexis Entity or
otherwise attributable to or derived from any of the Energy Rights and agrees that it shall
not authorize, commit or agree to take, and shall not permit any Affiliate, nor any
subsidiary, to authorize, commit or agree to take, any action that would be inconsistent
with this Section 5.10 or impair any portion of the MUS Interest.



     5.11 MUS not an Affiliate. Notwithstanding anything to the contrary, for purposes of
this Article 5, MUS shall not be considered, or deemed to be, an Affiliate of Codexis.




	7.	 	Article 12 of the Agreement is amended by the addition of new Section 12.7:






     12.7 Termination for Cause. In the event that Codexis materially breaches any
of its obligations pursuant to Article 5 of the Agreement, and such breach has continued for
sixty (60) days after receipt of written notice thereof from MUS, MUS may terminate any and
all rights received by Codexis under the terms of this Amendment No. 3.




	8.	 	Exhibit F shall be revised such that Exhibit F shall read in its entirety as attached to this
Amendment No. 3.
