	Re:
	Employment
Terms 

Dear
Geoff: 

        Anacor
Pharmaceuticals, Inc. (the "Company"), is pleased to offer you the position of Senior Vice President, Chief Financial Officer ("CFO"), on the following terms. Your
employment shall commence on September 13, 2010. 

 POSITION  

        You will serve in an executive capacity and shall perform the duties of CFO as commonly associated with this position and as required
by the Company. In this key position, you will primarily be responsible for overseeing or participating in financial plans and policies, accounting practices and procedures, and the organization's
relationship with the financial community. You will direct the controller function, accounting, treasure, tax, as well as investor relations, business development, legal and administration. You will
also serve as part of the management team and will participate in selected tasks as assigned by the Company. You will report to David Perry, the Chief Executive Officer of the Company. 

        You
will work at the Company's corporate headquarters which are currently located in Palo Alto, CA, subject to business travel. During your employment with the Company, you will devote
your best efforts and substantially all of your business time and attention (except for vacation periods and reasonable periods of illness or other incapacity permitted by the Company's general
employment policies or applicable law) to the business of the Company. The Company reserves the right to change your position, duties, reporting relationship, work location, job duties, and the
Company's general employment policies and procedures, from time to time in its discretion. 

        Your
employment relationship with the Company shall also be governed by the general employment policies and practices of the Company (except that if the terms of this letter differ from
or are in conflict with the Company's general employment policies or practices, this letter will control), and you will be required to abide by the general employment policies and practices of the
Company. 

 COMPENSATION  

        Your initial base salary will be paid at the rate of $27,916.67 per month, which is equivalent to $335,000 annually, less standard
payroll deductions and withholdings. You will be paid semi-monthly in accordance with Company practice and policy. As a full-time exempt employee, you will be expected to work
the Company's normal business hours and such additional time as may be required by the nature of your work assignments; and you will not be eligible for overtime compensation. 

        In
addition, you will be eligible to earn a performance bonus of up to thirty-five percent (35%) of your annual base salary ("Performance Bonus"). Twenty-five
percent (25%) of the Performance Bonus is contingent on your achievement of individual performance objectives as mutually established by you and the Company ("Individual Component") each year
(prorated for any partial year). The remaining seventy-five percent (75%) is contingent on the Company's achievement of its corporate objectives ("Company Component"). The Individual
Component of the Performance Bonus will be assessed on, and if earned, paid on a quarterly basis and prorated for your length of service. The Company will determine in its sole discretion, the level
of achievement of each Performance Bonus component. The Performance Bonus, if earned, will be paid less all applicable taxes and withholdings. As a condition precedent to earning and receiving a
Performance Bonus, you must remain an active employee with the Company through the date the bonus otherwise is scheduled to be paid. If your employment has been 

terminated
for any reason before such date, whether by you or the Company, then you will not be entitled to any Performance Bonus. 

        Your
compensation package will be reviewed on an annual or more frequent basis by the Board (or any authorized committee thereof), and are subject to change in the discretion of the
Board (or any authorized committee thereof). 

 STOCK OPTIONS  

        Subject to approval of the Company's Board of Directors (the "Board"), the Company will grant you an option (the "Option") to purchase
850,000 shares of the Company's common stock pursuant to the Company's 2001 Equity Incentive Plan (the "Plan") at an exercise price equal to the fair market value of the stock as of the date of grant
as determined by the Board. The Option will be subject to a four-year vesting period subject to your continued employment with the Company, with twenty-five percent (25%) of
the shares subject to the Option vesting on the one year anniversary of your vesting commencement date, and one-forty-eighth (1/48th) of the shares subject to the Option
vesting for each month of your continued service. The Option will be governed in full by the terms and conditions of the Plan and your individual Option agreement. 

 BENEFITS  

        You will be eligible to participate in the Company's standard employee benefit plans in accordance with the terms and conditions of the
plans and applicable policies which may be in effect from time to time, and provided by the Company to its executive employees generally, including but not limited to group health insurance coverage,
disability insurance, life insurance, and 401(k) Plan. In addition, in accordance with the Company's paid time off ("PTO") policies, you will accrue PTO at an annual rate of four (4) weeks or
twenty (20) days, subject to a maximum permitted accrual of thirty (30) days. In your fifth (5th) year of employment with the Company, you will accrue PTO at an annual rate
of five (5) weeks or twenty-five (25) days, subject to a maximum permitted accrual of thirty-eight (38) days. The Company may modify its benefits programs from time to
time in its discretion. 

 CHANGE OF CONTROL  

        In the event of a Change of Control of the Company, you will be entitled to the benefits set forth in the Change of Control Agreement
attached hereto as Attachment A, subject to the terms and conditions described in such agreement. 

 CONFIDENTIAL INFORMATION AND INVENTION ASSIGNMENT AGREEMENT  

        As a condition of employment, you are required to sign and abide by the Company's Confidential Information and Invention Assignment
Agreement (the "Confidential Information Agreement"), a form of which is attached hereto as Attachment
B. 

 PROTECTION OF THIRD PARTY INFORMATION  

        In your work for the Company, you will be expected not to use or disclose any confidential information or materials, including trade
secrets, of any former employer or other third party to whom you have an obligation of confidentiality; and not to violate any lawful agreement that you may have with any third party. By signing this
letter, you represent that you are able to
perform your job duties within these guidelines, and you are not in unauthorized possession of any confidential documents or other property of any former employer or other third party. In addition,
you represent that you have disclosed to the Company in writing any agreement you may have with any third party (e.g., a former employer) which may limit your ability to perform your duties to
the Company, or which otherwise could create a conflict of interest with the Company. 

 OUTSIDE ACTIVITIES  

        Throughout your employment with the Company, you may engage in civic and not-for-profit activities so long as
such activities do not interfere with the performance of your duties hereunder or present a conflict of interest with the Company. Subject to the restrictions set forth herein and with the prior
written consent of the Board, you may serve as a director of other corporations and may devote a reasonable amount of your time to other types of business or public activities not expressly mentioned
in this paragraph. The Board may rescind its consent to your service as a director of all other corporations or participation in other business or public activities, if the Board, in its sole
discretion, determines that such activities compromise or threaten to compromise the Company's business interests or conflict with your duties to the Company. 

        During
your employment by the Company, except on behalf of the Company, you will not directly or indirectly serve as an officer, director, stockholder, employee, partner, proprietor,
investor, joint venturer, associate, representative or consultant of any other person, corporation, firm, partnership or other entity whatsoever known by you to compete with the Company (or is
planning or preparing to compete with the Company), anywhere in the world, in any line of business engaged in (or planned to be engaged in) by the Company; provided, however, that you may purchase or
otherwise acquire up to (but not more than) one percent (1%) of any class of securities of any enterprise (but without participating in the activities of such enterprise) if such securities are listed
on any national or regional securities exchange. 

 AT-WILL EMPLOYMENT RELATIONSHIP  

        Your employment relationship with the Company is at-will. Accordingly, both you and the Company may terminate the
employment relationship at any time, with or without cause, and with or without advance notice. 

 SEVERANCE BENEFITS  

        If, at any time after an underwritten public offering by the Company of shares of its Common Stock pursuant to a registration statement
on Form S-1 (or any successor form) under the Securities Act of 1933, as amended (an "IPO"), (a) the Company terminates your employment without Cause (as defined herein), and
other than as a result of your death or disability, or (b) you resign for Good Reason (as defined herein), and provided such termination constitutes a "separation from service" (as defined
under Treasury Regulation Section 1.409A-1(h)) (a "Separation from Service"), you shall be entitled to receive the following
severance benefits: (i) severance pay in the form of a lump sum payment equal to nine (9) months of your base salary in effect on the effective date of termination; and (ii) if
you timely elect continued coverage under COBRA, then the Company shall pay the COBRA premiums necessary to continue your medical insurance coverage in effect for yourself and your eligible dependents
on the termination date for the first nine (9) months of such coverage (provided that such COBRA reimbursement shall terminate on such earlier date as you are no longer eligible for COBRA
coverage). If Separation from Service occurs before an IPO, then instead of the benefits in the foregoing sentence, you will be entitled to receive one hundred thousand (100,000) vested shares of
stock options. 

        Such
severance benefits are conditional upon (a) your continuing to comply with your obligations under your Confidential Information Agreement; and (b) your delivering to
the Company an effective, general release of claims in favor of the Company in a form acceptable to the Company within 30 days following your termination date. Any lump sum severance payment
will be subject to standard deductions and will be made on the 40th day following your termination. 

        For
purposes of this Agreement, "Cause" means (A) your conviction (including a guilty plea or a no contest plea) of a felony, or of
any other crime involving fraud, dishonesty or moral turpitude; (B) your attempted commission of or participation in a fraud or act of material dishonesty against the Company; (C) your
material breach of any written agreement between you and the Company (including but not limited to your Confidential Information Agreement) or material breach or neglect of any 

statutory
or fiduciary duty you owe to the Company; or (D) your conduct that constitutes gross insubordination, incompetence or habitual neglect of your duties as determined by the Board. 

        For
purposes of this Agreement, you shall have "Good Reason" for your resignation from your employment with the Company and/or any of its
subsidiaries or parent entities for up to ninety (90) days following the occurrence of one of the following events without your consent and after having provided thirty (30) days prior
written notice and an opportunity to cure to the Company and the
failure by the Company to cure the event: (A) material reduction in your duties (including responsibilities and/or authorities), provided,
however, that a change in job position (including a change in title) shall not be deemed a "material reduction" in and of itself unless your new duties are substantially
reduced from the prior duties; (B) relocation of your principal place of employment to a place that increases your one-way commute by more than fifty (50) miles as compared
to your then current principal place of employment immediately prior to such relocation; or (C) a reduction of at least 10% of your gross base salary (unless pursuant to a salary reduction
program applicable generally to the Company's executive employees). 

        It
is intended that the severance benefits payable under this letter satisfy, to the greatest extent possible, the exemptions from the application of Internal Revenue Code
Section 409A provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this letter will be construed to the greatest
extent possible as consistent with those provisions. Notwithstanding any provision to the contrary in this letter, if you are deemed by the Company at the time of your Separation from Service to be a
"specified employee" for purposes of Code Section 409A(a)(2)(B)(i), to the extent delayed commencement of any portion of the severance benefits to which you are entitled under this letter is
required in order to avoid a prohibited distribution under Code Section 409A(a)(2)(B)(i), such portion of your benefits shall not be provided to you prior to the earlier of (i) the
expiration of the six-month period measured from the date of your Separation from Service with the Company or (ii) the date of your death. Upon the first business day following the
expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph shall be paid in a lump sum to you, and any remaining payments due under this
letter shall be paid as otherwise provided herein. 

 MISCELLANEOUS  

        This letter, including the attached Confidential Information Agreement, constitutes the complete, final and exclusive embodiment of the
entire agreement between you and the Company with regard to the subject matter hereof. It is entered into without reliance on any promise or representation, written or oral, other than those expressly
contained herein, and it supersedes any other agreements, promises, warranties or representations concerning its subject matter. Changes in your employment terms, other than those expressly reserved
herein to the Company's or the Board's discretion, can only be made in a writing signed by a duly-authorized officer of the Company and you. This letter agreement will bind the heirs,
personal representatives, successors and assigns of both you and the Company, and inure to the benefit of both you and the Company, their heirs, successors and assigns. If any provision of this letter
agreement is determined to be invalid or unenforceable, in whole or in part, this determination shall not affect any other provision of this letter agreement and the provision in question shall be
modified so as to be rendered enforceable in a manner consistent with the intent of the parties insofar as possible under applicable law. This letter agreement shall be construed and enforced in
accordance with the laws of the State of California without regard to conflicts of law principles. Any ambiguity in this letter agreement shall not be construed against either party as the drafter.
Any waiver of a breach of this letter agreement, or rights hereunder, shall be in writing and shall not be deemed to be a waiver of any successive breach or rights hereunder. This letter agreement may
be executed in counterparts which shall be deemed to be part of one original, and facsimile signatures shall be equivalent to original signatures. 

        To
ensure the rapid and economical resolution of disputes that may arise under or relate to this Agreement, you and the Company agree that any and all disputes, claims, or causes of
action, in law or equity, arising from or relating to the enforcement, execution, or interpretation of this Agreement, your 

employment
or the termination of your employment (collectively, "Claims"), shall be resolved to the fullest extent permitted by law, by final, binding,
and (to the extent permitted by law) confidential arbitration conducted by JAMS, Inc. ("JAMS") before a single arbitrator in Palo Alto,
California in accordance with the applicable JAMS rules then in effect (except in the event such rules may conflict with this paragraph, the terms of this paragraph will control). Claims subject to
this arbitration provision shall (a) include, but not be limited to, Claims pursuant to any federal, state or local law or statute, including (without limitation) the Age Discrimination in
Employment Act, as amended; Title VII of the Civil Rights Act of 1964, as amended; the Americans With Disabilities Act of 1990; the federal Fair Labor Standards Act; the California Fair Employment and
Housing Act; and Claims pursuant to common law, tort law or contract law, including (without limitation) Claims for breach of contract or other promise, discrimination, harassment, retaliation,
wrongful discharge, fraud, misrepresentation, defamation and/or emotional distress; and (b) exclude Claims that by law are not subject to arbitration. The arbitrator shall: (a) have the
authority to compel adequate discovery for the resolution of all Claims and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision including
the arbitrator's essential findings and conclusions and a statement of the award. The Company shall pay all JAMS fees in excess of the amount of filing and other court-related fees you would have been
required to pay if the Claims were asserted in a court of law. You and the Company acknowledge that, by agreeing to this arbitration procedure, both you and the Company waive
the right to resolve any Claims through a trial by jury or judge or by administrative proceeding. Nothing in this letter agreement shall prevent either you or the Company from
obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Any awards or orders in such arbitrations may be entered and enforced as judgments in
the federal and state courts of any competent jurisdiction. 

        As
required by law, this offer is subject to satisfactory proof of your identity and right to work in the United States. 

        Please
sign this letter and the attached Confidential Information Agreement and return them to me within three (3) days to accept
employment with the Company on the terms set forth herein. Our employment offer will expire if we do not receive the fully signed letter and Confidential Information Agreement from you within this
timeframe. We are very excited about having you join us and look forward to working with you.

wages, bonuses or other compensation of employees of Lessor, including fringe benefits, or any fee, office overhead or general and administrative expenses paid to
Lessor or its affiliates for management and administration of the Premises in excess of the management fee referred to in Paragraph 4(b) of this Lease; 

        (6)   Costs
incurred to correct any defects in the Premises of which Lessee gives Lessor written notice prior to the expiration of the warranty period referred to in
Paragraph 12(c) hereof; 

        (7)   Costs
to correct any construction defect in the Premises resulting from construction performed after the Commencement Date pursuant to any construction contract to which
Lessor is the owner party; 

3

 

        (8)   Costs
in the nature of depreciation, amortization or other expense reserves; and 

        (9)   Costs
incurred as a result of casualties or by the exercise of the power of eminent domain. 

        Lessor
shall at all times use its best efforts to operate the Premises in an economically reasonable manner at costs not disproportionately higher than those experienced by other
comparable premises in the market area in which the Premises are located. 

        (e)   During
December of each calendar year of the term, commencing December 2002, Lessor shall notify Lessee in writing of Lessor's good faith estimate of the
Operating Expenses and Taxes for the following calendar year. Lessor shall include with such notice a description of the Operating Expenses and Taxes. Commencing on January 1, 2003, and on the
first (1st) day of every calendar month of the term
thereafter, Lessee shall pay to Lessor monthly in advance, as Additional Rent, one-twelfth (1/12th) of the estimated Operating Expenses and Taxes for the current calendar year. If during
the term it appears to Lessor that the Operating Expenses or Taxes for the current calendar year will vary from Lessor's estimate, Lessor may, by written notice to Lessee, revise Lessor's estimate
Operating Expenses or Taxes for the current calendar year and the Additional Rent and Taxes payments by Lessee for such calendar year shall thereafter be based upon such revised estimate. Lessor shall
furnish to Lessee with such revised estimate written documentation supporting Lessor's revised estimate. The increase in the monthly installments of Additional Rent and Taxes resulting from Lessor's
revised estimate shall not be retroactive, but the Additional Rent and Taxes for such calendar year shall be subject to adjustment between Lessor and Lessee following the end of each calendar year as
provided below. 

        Within
ninety (90) days after the end of each calendar year during the term, Lessor shall furnish Lessee a statement certified by a responsible employee or agent of Lessor (the
"Operating Statement") with respect to the term of the Lease prepared by an employee or agent of Lessor, showing Operating Expenses and Taxes for the prior calendar year broken down by component
expenses, and the total payments made by Lessee on the basis of any previous estimate of such Operating Expenses and Taxes, all in sufficient detail for verification by Lessee. Unless Lessee raises
any objections to the Operating Statement within thirty (30) days after Lessee's receipt of the Operating Statement, such statement shall conclusively be deemed correct and Lessee shall have no
right thereafter to dispute such statement or any item therein or the computation of Operating Expenses and/or Taxes. Lessee and its accountants shall have the right to inspect and audit Lessor's
books and records with respect to this Lease once within thirty (30) days after Lessee's receipt of the Operating Statement to verify actual Operating Expenses and/or Taxes for the prior
calendar year. Lessor's books and records shall be kept in accordance with generally accepted accounting principles. If Lessee's audit of the Operating Expenses and/or Taxes reveals a net overcharge
of more than five percent (5%), Lessor promptly shall reimburse Lessee for the reasonable cost of the audit; otherwise, Lessee shall bear the cost of Lessee's audit. In addition to Lessee's audit
rights, Lessor shall, at Lessee's request from time to time, meet and confer with Lessee to review and discuss Operating Expenses and Taxes and the management, maintenance, and repair of the Premises
so that Operating Expenses and Taxes can be maintained at a commercially reasonable level. 

        Within
thirty (30) days after Lessee's receipt of Lessor's Operating Statement or the completion of Lessee's audit regarding the Operating Expenses and/or Taxes for each calendar
year during the term of this Lease or the period through the Expiration Date or termination date of this Lease, Lessee shall pay to Lessor or shall receive from Lessor, as the case may be, an amount
equal to the difference between the Operating Expenses and/or Taxes for the calendar year or period, as finally determined, and the amount previously paid by Lessee on account thereof (prorated to the
Expiration Date or the termination date of this Lease). 

4

 

 
        5.    Payment of Rent.    

        (a)   All
rent shall be due and payable by Lessee in lawful money of the United States of America at the address of Lessor set forth in Paragraph 23, "Notices," without
deduction or offset and without prior demand or notice, unless otherwise specified herein. Monthly Base Rent and Additional Rent shall be payable monthly, in advance, on the first (1st) day of each
calendar month. Lessee's obligation to pay rent for any partial month at the commencement or expiration or termination of the Lease term shall be prorated on the basis of the actual number of days in
such calendar month. 

        (b)   If
any installment of Monthly Base Rent, Additional Rent or any other sum due from Lessee is not received by Lessor within five (5) days after receipt by Lessee
of written notice from Lessor that the same is due, Lessee shall pay to Lessor an additional sum equal to five percent (5%) of the amount overdue as a late charge. The parties agree that this late
charge represents a fair and reasonable estimate of the costs that Lessor will incur by reason of the late payment by Lessee. Acceptance of any late charge shall not constitute a waiver of Lessee's
default with respect to the overdue amount. Any amount not paid within five (5) days after Lessee's receipt of written notice that such amount is due shall bear interest from the date due until
paid at the lesser rate of (1) the prime rate of interest plus five percent (5%) or (2) the maximum rate allowed by law, in addition to the late payment charge (the "Interest Rate").

         6.    Letter of Credit.    

        (a)   Concurrently
with the execution and delivery of this Lease, Lessee shall deliver to Lessor as security for the payment by Lessee of the rent or any other sum due and
owing during the term of this Lease, an irrevocable and unconditional letter of credit governed by the Uniform Customs and Practice for Documentary Credits (1993 revisions), International Chamber of
Commerce Publication No. 500, as revised from time to time, in the amount of Fifty-five Thousand Eighty Dollars ($55,080) (the "Letter of Credit") naming Lessor as beneficiary. The
form of the Letter of Credit and the issuer thereof shall be subject to approval by Lessor. 

        (b)   The
amounts necessary for Lessor to recover any rent or other sum in default (beyond applicable notice and cure periods), or to recover the payment of any amount that
Lessor may spend or may become obligated to spend by reason of Lessee's uncured default (beyond applicable notice and cure periods) or to compensate Lessor for any loss or damage which Lessor has
suffered thereby shall be available under the Letter of Credit to Lessor upon presentation to the issuer of Lessor's sight draft accompanied only by the Letter of Credit and Lessor's signed statement
that Lessor is entitled to draw on the Letter of Credit pursuant to this Lease. The Letter of Credit shall be maintained in effect, whether through renewal or extension, for the entire period from the
Commencement Date of this Lease and continuing until the date (the "LC Expiration Date") which is one hundred twenty (120) days after the expiration of the Lease term, and Lessee shall deliver
a new Letter of Credit or certificate of renewal or extension to Lessor at least thirty (30) days prior to the expiration of the Letter of Credit then held by Lessor, without any action
whatsoever on the part of Lessor. The Letter of Credit shall state that the failure of Lessee to deliver to Lessor a new Letter of Credit or a certificate of renewal or extension at least thirty
(30) days prior to the expiration of the Letter of Credit shall constitute a default by Lessee that shall entitle Lessor to draw the entire amount of the existing Letter of Credit. The Letter
of Credit shall expressly state that the Letter of Credit and the right to draw thereunder may be transferred or assigned by Lessor to any successor or lessee of Lessor's interest in the Premises.
Lessee shall pay any fees related to the issuance or amendment of the Letter of Credit, excluding, however, any transfer fees, which shall be paid by Lessor. If Lessee is not then in Default under 

5

 

this
Lease, Lessor shall return the Letter of Credit to Lessee within thirty (30) days after the end of the term. 

        7.    Use.    Subject to Lessee obtaining at Lessee's sole cost and expense all necessary governmental permits and
approvals therefor, Lessee shall have the right to use the Premises for general office use, laboratory use (including, without limitation, tissue culture, radiation facilities and chemistry
laboratories), research and development, and manufacturing of biotechnology products, keeping of live animals for research purposes and for such other uses permitted by applicable zoning ordinances
and any covenants, conditions, and restrictions affecting the Premises ("Permitted Uses"), and for no other use or purpose without Lessor's prior written consent. Any use of the Premises by any
assignee or sublessee of Lessee pursuant to Paragraph 16 shall comply with the provisions of this Paragraph 7. Except for Lessor's representations and warranties contained in
Paragraph 12(d), Lessor does not make any representation or warranty to Lessee (1) regarding the suitability of the Premises, or the suitability of the electrical and other systems of
the Building, for Lessee's Permitted Uses thereof, or (2) that the Premises may be lawfully used for Lessee's intended purposes, and Lessor shall have no liability whatsoever to Lessee if any
such use is not permitted by applicable zoning or under any other law or ordinance, and this Lease shall not be construed to imply any such representation or warranty. 

        8.    Environmental Matters.    

        (a)   The
term "Hazardous Materials" as used in this Lease shall mean any product, substance, or waste whose presence, use, manufacture, disposal, transportation, or release,
is regulated or monitored by any governmental authority pursuant to Environmental Laws. Hazardous Materials shall include, but not be
limited to hydrocarbons, petroleum, gasoline, and/or crude oil or any products, by-products or fractions thereof. 

        (b)   "Environmental
Laws" shall mean and include any Federal, State, or local statute, law, ordinance, code, rule, regulation, order, or decree regulating, relating to, or
imposing liability or standards of conduct concerning, any hazardous, toxic, or dangerous waste, substance, element, compound, mixture or material, as now or at any time hereafter in effect including,
without limitation, California Health and Safety Code §§25100 et seq., §§25300 et seq., Sections 25281(f) and 25501 of the California Health and Safety
Code, Section 13050 of the Water Code, the Federal Comprehensive Environmental Response, Compensation and Liability Act, as amended, 42 U.S.C. §§9601 et seq. ("CERCLA"),
the Superfund Amendments and Reauthorization Act, 42 U.S.C. §§9601 et seq., the Federal Toxic Substances Control Act, 15 U.S.C. §§2601 et seq., the
Federal Resource Conservation and Recovery Act as amended, 42 U.S.C. §§6901 et seq., the Federal Hazardous Material Transportation Act, 49 U.S.C. §§1801
et seq., the Federal Clean Air Act, 42 U.S.C. §7401 et seq., the Federal Water Pollution Control Act, 33 U.S.C. §1251 et seq., the River and Harbors Act of 1899, 33 U.S.C.
§§401 et seq., and all rules and regulations of the EPA, the California Environmental Protection Agency, or any other state or federal department, board or any other agency or
governmental board or entity generally having jurisdiction over the environment, as any of the foregoing have been, or are hereafter amended. 

        (c)   Lessee
shall not use, store, or transport to or from the Premises, or dispose of any Hazardous Materials except the Hazardous Materials listed on Exhibit "C" attached
hereto and incorporated by reference herein, and ordinary and customary office supplies and cleaning materials which are used in the normal course of Lessee's agreed use of the Premises. All such
Hazardous Materials (1) shall be used, stored, transported, and disposed of in strict compliance with Environmental Laws, and (2) shall be stored on the Premises only in limited quantity
required for the business at the Premises. Except as listed on Exhibit "C," as Exhibit "C" may be amended and supplemented from time to time with Lessor's prior written consent, and except as
otherwise specifically permitted by this Paragraph 8(c), Lessee shall not use, store, transport, or dispose of any Hazardous Materials in or about the Premises. Without limiting the generality
of the 

6

 

foregoing,
Lessee shall, at its sole cost, comply with all Environmental Laws relating to Hazardous Materials that Lessee uses, stores, transports, or disposes in or about the Premises. If Hazardous
Materials are discovered at or about the Premises in violation of Environmental Laws and such Hazardous Materials were used, stored, transported, or disposed of by Lessee, then Lessee shall, at
Lessee's sole expense, promptly take all action necessary to cause the Premises to comply with all Environmental Laws with respect to such Hazardous Materials and if and such Hazardous Materials were
not used, stored, transported, or disposed of by Lessee, then Lessor shall take all action necessary to cause the Premises to comply with all Environmental Laws with respect to such Hazardous
Materials. Lessee shall deliver to Lessor a copy of Lessee's current Hazardous Materials Management Plan, and any amendments or supplements thereto, or replacements thereof, from time to time during
the term of this Lease, and a copy of all Hazardous Materials reports or plans filed by Lessee with the City of Palo Alto, even though Lessee's Hazardous Materials Management Plan and any such reports
on plans filed with the City show that Lessee is not currently using any reportable Hazardous Materials
on the Premises. Lessee shall not be responsible for the containment of or any other disposal or remediation measures relating to Hazardous Materials used, stored, transported, or disposed of on the
Premises by previous lessees or by Lessor. Lessor shall provide Lessee with a copy of the closure plan implemented by the previous lessee of the Premises and any related reports and certificates from
governmental authorities relating to such closure. 

        (d)   If
Lessee knows, or has reasonable cause to believe, that Hazardous Materials have come to be located in, on, under or about the Premises, other than as shown on Exhibit
"C" or previously approved in writing by Lessor, Lessee shall immediately give written notice of such fact to Lessor and provide Lessor with a copy of any report, notice, claim or other documentation
which it has concerning the presence of such Hazardous Materials. 

        (e)   Lessee
shall indemnify, defend with counsel reasonably acceptable to Lessor, and hold Lessor harmless from any and all claims, damages, fines, judgments, penalties,
costs, liabilities or losses (including, without limitation, any and all sums paid for settlement of claims, attorneys' fees, consultant and expert fees) arising during or after the term (as such may
be extended) from the use, storage, transportation, release, disposal, discharge, or emission of Hazardous Materials at or about the Premises by Lessee, or Lessee's employees, agents, contractors, or
invitees. Without limitation of the foregoing, this indemnification shall include any and all costs incurred due to any investigation of the site or any cleanup, removal or restoration mandated by a
federal, state or local agency or political subdivision and any repairs to the Premises required in connection therewith. The foregoing indemnity shall survive the expiration or earlier termination of
this Lease. 

        (f)    Lessor
represents and warrants that, to the best of Lessor's knowledge as of the date of this Lease, (1) no Hazardous Materials are currently present in the
Building or at the Premises, or the soil, surface water, or ground water thereof; (2) no underground storage tanks are present at the Premises; and (3) no action, proceeding, or claim is
pending or threatened regarding the Building or the Premises concerning any Hazardous Materials or pursuant to any Environmental Law. 

        (g)   Prior
to the expiration of the term and the surrender of possession of the Premises by Lessee to Lessor, Lessee shall obtain at Lessee's expense an environmental closure
report certified by the appropriate department of the City of Palo Alto and a copy of such certification shall be delivered to Lessor. Such closure shall include the removal and remediation at
Lessee's expense, in accordance with and to the extent required by applicable laws and governmental regulatory agencies, of any Hazardous Materials in, on, under, or about the Premises released or
discharged by Lessee, its Permitted Affiliates, sublessees, assignees, employees, agents, contractors, or invitees. 

7

 

        (h)   The
provisions of this Paragraph 8 shall survive the expiration or earlier termination of the term of this Lease. 

        9.    Taxes on Lessee's Property.    Lessee shall pay before delinquency any and all taxes, assessments, license fees,
and public charges levied, assessed, or imposed and which become payable during the term upon Lessee's equipment, fixtures, furniture, and personal property installed or located in the Premises and
any such property owned by Lessor. 

        10.    Insurance.    

        (a)   Lessee
shall, at Lessee's sole cost and expense, provide and keep in force commencing with the date of Lessee's early entry to the Premises pursuant to
Paragraph 1(b) hereof and continuing during the Lease term, a commercial general liability insurance policy with a recognized casualty insurance company qualified to do business in California,
insuring against any and all liability occasioned by any occurrence in, on, about, or related to the Premises, or arising out of the condition, use, occupancy, alteration or maintenance of the
Premises, having a combined single limit for both bodily injury and property damage in an amount not less than Three Million Dollars ($3,000,000). Lessee's liability insurance policy shall contain
cross liability endorsements, shall insure performance by Lessee of the indemnity agreements contained in Paragraph 11(a), and shall name Lessor and Lessor's property manager as additional
insureds. All such insurance carried by Lessee shall be in a form reasonably satisfactory to Lessor and its mortgage lender and shall be carried with companies that have a general policyholder's
rating of not less than "A" and a financial rating of not less than Class "X" in the most current edition of Best's Insurance Reports; shall provide that such policies shall not be subject to material
alteration or cancellation except after at least thirty (30) days' prior written notice to Lessor; and shall be primary and not contributory. Prior to the Commencement Date and upon renewal of
such policies not less than fifteen (15) days prior to the expiration of the term of such coverage, Lessee shall deliver to Lessor certificates of insurance confirming such coverage, together
with evidence of the payment of the premium therefor. If Lessee fails to procure and maintain the insurance required hereunder, Lessor may, but shall not be required to, order such insurance at
Lessee's expense and Lessee shall reimburse Lessor for all costs incurred by Lessor with respect thereto. Lessee's reimbursement to Lessor for such amounts shall be deemed Additional Rent, and shall
include all sums disbursed, incurred or deposited by Lessor, including Lessor's costs, expenses and reasonable attorneys' fees with interest thereon at the Interest Rate. 

        (b)   Lessor
shall obtain and carry in Lessor's name, as insured, as an Operating Expense of the Premises as provided in Paragraph 4(b), during the lease term, "all
risk" property insurance coverage (with rental loss insurance coverage for a period of one year), flood insurance, public liability and property damage insurance, and insurance against such other
risks or casualties as Lessor shall determine, including, but not limited to, insurance coverages required of Lessor by the beneficiary of any deed of trust which encumbers the Property (excluding
earthquake insurance coverage), insuring Lessor's interest in the Premises, any other improvements to the Premises constructed by Lessor, or by Lessee with Lessor's prior written approval, in an
amount not less than the full replacement cost of the Building and all other Improvements from time to time. The proceeds of any such insurance shall be payable solely to Lessor and Lessee shall have
no right or interest therein. Lessor shall have no obligation to insure against loss by Lessee to Lessee's equipment, furniture, fixtures, inventory, or other personal property of Lessee in, on, or
about the Premises occurring from any cause whatsoever. Lessor's commercial
general liability insurance shall provide for contractual liability referred to in Paragraph 11(b) of this Lease. 

8

 

 

        (c)   Notwithstanding
anything to the contrary contained in this Lease, the parties release each other, and their respective authorized representatives, employees, officers,
directors, shareholders, managers, members, assignees, subtenants, and property managers, from any claims for damage to any person or to the Premises and to the fixtures, personal property, leasehold
improvements and alterations of either Lessor or Lessee in or on the Premises that are caused by or result from risks required by this Lease to be insured against or actually insured against under any
property insurance policies carried by the parties and in force at the time of any such damage, whichever is greater. This waiver applies whether or not the loss is due to the negligent acts or
omissions of Lessor or Lessee or their respective officers, directors, employees, agents, contractors, or invitees. 

        (d)   Each
party shall cause each property insurance policy obtained by it to provide that the insurance company waives all right of recovery by way of subrogation against
either party in connection with the above waiver and any damage covered by any policy; provided, however, that such provision or endorsement shall not be required if the applicable policy of insurance
permits the named insured to waive rights of subrogation on a blanket basis, in which case the blanket waiver shall be acceptable. Neither party shall be liable to the other for any damage caused by
fire or any of the risks insured against under any policy of insurance carried pursuant to this Lease. 

        11.    Indemnification.    

        (a)   Lessee
waives all claims against Lessor for damage to or loss of Lessee's equipment, furniture, fixtures, supplies, product inventory, or other personal property of
Lessee or any other person in, upon, or about the Premises, and for injuries to persons in, upon, or about the Premises from any cause arising at any time, except as may be caused by the negligence or
willful misconduct of Lessor or its employees, agents or contractors, or Lessor's failure to perform any of its obligations under this Lease or that arise from any breach of any of Lessor's
warranties. Except as provided in Paragraph 10(c), Lessee shall indemnify, defend, and hold harmless ("Indemnify") Lessor from claims, suits, actions, or liabilities (collectively, "Losses")
for personal injury, death or for loss or damage to property that arise from (1) any activity, work, or thing done, or permitted by Lessee in or about the Premises, (2) for bodily injury
or damage to property which arises in or about the Building or the Premises to the extent
the injury or damage to property results from the negligent acts or omissions of Lessee, its employees, agents or contractors, and (3) arising from a breach of this Lease by Lessee in the
performance of any obligation on Lessee's part to be performed under this Lease, provided, however, that Lessee shall not be responsible to Indemnify Lessor for any Losses caused by the negligence or
willful misconduct of Lessor or its employees, agents or contractors, or Lessor's failure to perform any of its obligations or breach of any warranty by Lessor under this Lease. 

        (b)   Except
as provided in Paragraph 10(c), Lessor shall indemnify, defend, and hold harmless Lessee from claims, suits, actions, or liabilities for personal injury,
death or for loss or damage to property except as may be caused by the negligence or willful misconduct of Lessee or its employees, agents, or contractors, or Lessee's failure to perform any of its
obligations or breach of any warranty by Lessee under this Lease. 

        (c)   The
foregoing indemnities by Lessee and Lessor shall also include reasonable costs, expenses and attorneys' fees incurred in connection with any indemnified claim or
incurred by the indemnitee in successfully establishing the right to indemnity. The indemnitor shall have the right to assume the defense of any claim subject to the foregoing indemnities with counsel
reasonably satisfactory to the indemnitee. The indemnitee agrees to cooperate fully with the indemnitor and its counsel in any matter where the indemnitor elects to defend, provided the indemnitor
shall promptly reimburse the indemnitee for reasonable costs and expenses incurred in connection with its duty to cooperate. 

9

 

        The
foregoing indemnities are conditioned upon the indemnitee providing prompt notice to the indemnitor of any claim or occurrence that is likely to give rise to a claim, suit, action or
liability that will fall within the scope of the foregoing indemnities, along with sufficient details that will enable the indemnitor to make a reasonable investigation of the claim. 

        When
the claim is caused by the joint negligence or willful misconduct of Lessee and Lessor or by the indemnitor party and a third party unrelated to the indemnitor party (except
indemnitor's agents, officers, employees or invitees), the indemnitor's duty to indemnify and defend shall be proportionate to the indemnitor's allocable share of joint negligence or willful
misconduct. 

        (d)   Notwithstanding
anything to the contrary contained herein, Lessor shall not be liable to Lessee, or to any of Lessee's employees, agents, contractors, or invitees for
any damage because of any act or negligence of any owner or occupant of adjoining or contiguous property or other third person, or for overflow, breakage, or leakage of water, steam, gas, or
electricity from pipes, wires, or otherwise in the Premises or the Building. 

        12.    Condition of the Premises.    

        (a)   Lessor
shall deliver the Premises to Lessee on the Commencement Date with the Building in broom clean condition. Prior to the Commencement Date Lessor, at its cost,
shall: (1) cause the trailers in the parking lot to be removed; (2) remove and retreat the windows with proper coating; (3) power wash the exterior of the Building;
(4) review and replace the landscaping as needed and place the sprinkler system in working condition; (5) repaint the accent stripe on the exterior of the Building; and
(6) inspect the parking lot and seal and restripe the parking lot if necessary. 

        (b)   Lessor
shall also construct at Lessor's expense ten (10) offices in the right front section of the existing office area of the Building. Lessor shall be
responsible for installation of sprinklers if required by the building code relating to Lessor's tenant improvement work. 

        (c)   If
Lessor's tenant improvement work, Lessee's tenant improvement work, or Lessee's proposed use of the Premises as described in Paragraph 7, triggers the
requirement under the building code for seismic upgrading of the Building or the requirement that sprinklers be installed elsewhere in the Building, Lessor and Lessee shall each pay
one-half of (1) the cost of the seismic upgrading, and (2) the cost of installation of the additional sprinklers required, in addition to the sprinklers to be installed by
Lessor pursuant to Paragraph 12(b) if required. 

        (d)   Lessor
represents and warrants to Lessee that (1) the HVAC system and the mechanical, electrical, gas (if any), and plumbing systems of the Building shall be in
good working order as of the Commencement Date, (2) the structural elements of the roof, bearing walls and foundation of the Building shall be free of material defects as of the Commencement
Date, (3) the tenant improvement work performed by Lessor pursuant to Paragraphs 12(a) and 12(b) shall be completed in a good and workmanlike manner, and (4) to Lessor's knowledge, the
telephone, water, sewer, electricity, gas, and other utility lines connected to the Building are in good working order from edge of Lessor's property to their point of connection in the Building
walls. If a noncompliance with such warranty exists as of the Commencement Date, or if one of such systems or elements should malfunction or fail, or a material defect in Lessor's tenant improvement
work performed pursuant to Paragraphs 12(a) or 12(b) should become apparent, within ninety (90) days after the Commencement Date, Lessor shall, as Lessor's sole obligation with respect to such
matter, except as otherwise provided in this Lease, promptly after receipt of written notice from Lessee setting forth with specificity the nature and extent of such non-compliance,
malfunction, failure, or defect, rectify the same at Lessor's expense. If Lessee does not give Lessor the required notice within the ninety (90) day warranty period, correction of any such
non-compliance, 

10

 

malfunction,
failure, or defect shall be performed by Lessor and the cost thereof shall be an Operating Expense payable by Lessee pursuant to Paragraph 4 hereof. 

        (e)   Lessor
shall make available to Lessee for Lessee's use without additional charge the existing furniture, fixtures, and equipment listed on Exhibit "D" attached hereto in
its "as is" condition as of the Commencement Date. Such property shall remain the property of Lessor and shall be surrendered to Lessor upon the expiration or sooner termination of the term of this
Lease in a condition comparable to the condition of such property on the Commencement Date, reasonable wear and tear excepted. 

        (f)    Except
for the foregoing provisions of this Paragraph 12, Lessee shall accept the Premises on the Commencement Date in its "as is" condition. Lessee shall install
at Lessee's sole expense the initial improvements described on Exhibit "E" attached hereto and made a part hereof, and any additional laboratory upgrades, including, but not limited to, installation
of gas lines, sinks, and laboratory benches required for Lessee's Permitted Uses of the Premises, including, but not limited to, Lessee's chemistry and biology laboratories and animal facility. 

        (g)   Lessee
waives all right to make repairs at the expense of Lessor (except as set forth in Paragraph 28 below), or to deduct the costs thereof from the rent, and
Lessee waives all rights under Section 1941 and 1942 of the Civil Code of the State of California. 

        13.    Maintenance and Repairs; Alterations; Surrender and Restoration.    

        (a)   Lessor
shall, at Lessor's expense, keep in good order, condition, and repair and replace when necessary, the structural elements of the foundation and exterior walls
(except the interior faces thereof) of the Building, excluding any alterations, structural or otherwise, made by Lessee to the Building which are not approved in writing by Lessor prior to the
construction or installation thereof by Lessee. 

        (b)   In
addition to the items referred to in Paragraph 4(b), Lessor shall repair and maintain as an Operating Expense pursuant to Paragraph 4 hereof, the roof
and the roof membrane, the areas of the Premises outside the Building, including the landscaping, tree trimming, resurfacing and restriping of the parking lot and walkways, exterior building lighting,
and parking lot lighting (subject to amortization of the cost thereof if the cost is a capital expenditure as provided in Paragraph 4(b)). In the event Lessee provides Lessor with written
notice of the need for any repairs to the Premises, Lessor shall commence any such repairs promptly following receipt by Lessor of such notice and Lessor shall diligently prosecute such repairs to
completion. 

        (c)   Subject
to the foregoing and except as provided elsewhere in this Lease, Lessee shall at all times at Lessee's expense keep the Premises in good and safe order,
condition, and repair. Lessee shall contract for and pay directly for the janitorial service to the Building. Lessee shall execute and maintain in full force and effect at Lessee's expense throughout
the term a service contract with an authorized air conditioning service company for periodic service, repairs, and replacement of parts. Lessor shall have the right to obtain on a
semi-annual basis an inspection report of the HVAC system
from an HVAC service firm designated by Lessor for the purpose of monitoring the performance of the HVAC maintenance and repair work performed by Lessee's HVAC service firm. The cost of such
inspection report shall be an Operating Expense pursuant to Paragraph 4(b). Subject to the release of claims and waiver of subrogation contained in Paragraphs 10(c) and 10(d), if Lessor is
required to make any repairs by reason of Lessee's negligent acts or omission to act, Lessor may add the cost of such repairs to the next installment of rent which shall thereafter become due, and
Lessee shall promptly pay the same upon receipt of an invoice therefor. 

        (d)   Lessee
may, from time to time, at its own cost and expense and without the consent of Lessor make nonstructural alterations to the interior of the Premises the cost of
which in any one 

11

 

instance
is Fifty Thousand Dollars ($50,000) or less, and the aggregate cost of all such work during the term of this Lease does not exceed Two Hundred Fifty Thousand Dollars ($250,000), provided
Lessee first notifies Lessor in writing of any such nonstructural alterations. Otherwise, Lessee shall not make any additional alterations, improvements, or additions to the Premises without
delivering to Lessor a complete set of plans and specifications for such work and obtaining Lessor's prior written consent thereto, which consent shall not be unreasonably withheld or delayed. If any
nonstructural alterations to the interior of the Premises exceed Fifty Thousand Dollars ($50,000) in cost in any one instance, or exceed the aggregate cost of Two Hundred Fifty Thousand Dollars
($250,000) during the term of this Lease, Lessee shall employ, at Lessee's expense, a qualified licensed general contractor to perform such alterations pursuant to a construction contract entered into
between Lessee and such contractor. The contractor and the construction contract shall be subject to Lessor's written approval prior to commencement of construction, which approval shall not be
unreasonably withheld or delayed. Lessor may condition its consent to Lessee agreeing in writing to remove any such alterations prior to the expiration of the Lease term and Lessee agreeing to restore
the Premises to its condition prior to such alterations at Lessee's expense. Lessor shall advise Lessee in writing at the time consent is granted whether Lessor reserves the right to require Lessee to
remove any alterations from the Premises prior to the termination of this Lease. 

        All
alterations, trade fixtures and personal property installed in the Premises solely at Lessee's expense shall during the term of this Lease remain the property of Lessee, and Lessee
shall be entitled to all depreciation, amortization and other tax benefits with respect thereto. Lessee may remove any of Lessee's personal property, furniture, or equipment which is not affixed to
the Building in such a manner that it becomes a part of the Improvements ("Lessee's Personal Property") at any time and from time to time. Lessor shall have no lien or other interest whatsoever in any
item of Lessee's Personal Property. Within ten (10) days following Lessee's request from time to time, Lessor shall execute documents in commercially reasonable form to evidence Lessor's waiver
of any right, title, lien or interest in any of Lessee's Personal Property and giving any lenders holding a security interest or lien on such property reasonable rights of access to the Premises to
remove Lessee's Personal Property, provided that such lenders agree to repair all damage caused by such removal. Upon the expiration or sooner termination of this Lease all alterations, fixtures and
improvements to the Premises, whether made by Lessor or installed by Lessee at Lessee's expense, shall be surrendered by Lessee with the Premises and shall become the property of Lessor, provided,
however, that Lessee shall retain ownership or (1) Lessee's Personal Property, (2) any alterations, fixtures or improvements that, at the time of installation or thereafter, Lessor has
agreed that Lessee may retain ownership of and may remove, and (3) any alterations, fixtures or improvements that Lessor requires Lessee to remove. 

        (e)   Lessee,
at Lessee's sole cost and expense, shall during the term of this Lease promptly and properly observe and comply with all existing and future orders, regulations,
rules, laws, and ordinances of all governmental agencies or authorities, and the Board of Fire Underwriters ("Laws"). Any structural changes or repairs or other repairs or changes of any nature which
would be considered a capital expenditure under generally accepted accounting principles to the Premises shall be made by Lessor at Lessee's expense if such structural repairs or changes are required
by reason of the specific nature of the use of the Premises by Lessee. If such structural changes or repairs are not required by reason of the specific nature of Lessee's use of the Premises, the cost
of such structural changes or repairs, except as provided in Paragraph 13(a), shall be treated as an Operating Expense, and if such work is a capital expenditure the cost thereof shall be
amortized in accordance with the provisions of Paragraph 4(b). 

        (f)    Lessee
shall surrender the Premises by the last day of the Lease term or any earlier termination date, with all of the improvements to the Premises, parts, and surfaces
thereof clean 

12

 

and
free of debris and in good operating order, condition, and state of repair, ordinary wear and tear excepted. "Ordinary wear and tear" shall not include any damage or deterioration that would have
been prevented by good maintenance practice or by Lessee performing all of its obligations under this Lease. The obligations of Lessee shall include the repair of any damage occasioned by the
installation, maintenance, or removal of Lessee's trade fixtures, furnishings, equipment, and alterations, and the restoration by Lessee of the Premises to its condition prior to any alterations,
additions, or improvements (1) if Lessor's consent thereto was conditioned upon such removal and restoration upon expiration or sooner termination of the Lease term pursuant to
Paragraph 13(d), or (2) if Lessee made any such alterations, additions, or improvements without obtaining Lessor's prior written consent in breach of Paragraph 13(d) and within a
reasonable time after the expiration or sooner termination of the Lease term Lessor gives written notice to Lessee requiring Lessee to perform such removal and restoration. 

        14.    Utilities and Services.    

        (a)   Lessee
shall contract for and pay for all electricity, telephone, gas, water, heat and air conditioning service, janitorial service, refuse pick-up, sewer
charges, and all other utilities or services supplied to or consumed by Lessee, its agents, employees, contractors, and invitees on or about the Premises. 

        (b)   Lessor
shall not be liable to Lessee for any interruption or failure of any utility services to the Building or the Premises which is not caused by the negligence or
willful acts of Lessor, or Lessor's employees, agents, or contractors. Lessee shall not be relieved from the performance of any covenant or agreement in this Lease because of any such interruption or
failure, unless the interruption or failure is caused by the negligence or willful acts of Lessor, or Lessor's employees, agents, or
contractors in which case Lessee shall be entitled, in addition to any other remedy at law, to an abatement or rent in proportion to and for the duration of time that the interruption or failure
prevents Lessee from using the Premises for the Permitted Uses. 

        15.    Liens.    Lessee agrees to keep the Premises free from all liens arising out of any improvement work performed
by Lessee or arising out of any other work performed, materials furnished, or obligations incurred by Lessee. Lessee shall give Lessor at least ten (10) days prior written notice before
commencing any work of improvement on the Premises, the contract price for which exceeds Ten Thousand Dollars ($10,000). Lessor shall have the right to post notices of non-responsibility
with respect to any such work. If Lessee shall, in good faith, contest the validity of any such lien, claim or demand, then Lessee shall, at its sole expense, defend and protect itself, Lessor and the
Premises against the same, and shall pay and satisfy any such adverse judgment that may be rendered thereon or provide a lien release bond in accordance with applicable law before the enforcement
thereof against the Lessor or the Premises. 

        16.    Assignment and Subletting.    

        (a)   Except
as otherwise provided in this Paragraph 16, Lessee shall not assign this Lease, or any interest therein, voluntarily or involuntarily, and shall not sublet
the Premises or any part thereof, or any right or privilege appurtenant thereto, without the prior written consent of Lessor in each instance pursuant to the terms and conditions set forth below,
which consent shall not be unreasonably withheld, subject to the following provisions. 

        (b)   Prior
to any assignment or sublease which Lessee desires to make, Lessee shall provide to Lessor the name and address of the proposed assignee or sublessee, true and
complete copies of all documents relating to Lessee's prospective agreement to assign or sublease, a copy of a current financial statement for such proposed assignee or sublessee, and Lessee shall
specify all consideration to be received by Lessee for such assignment or sublease in the form of lump sum payments, installments of rent, or otherwise. For purposes of this Paragraph 16, the
term 

13

 

"consideration"
shall include all money or other consideration to be received by Lessee for such assignment or sublease. Within ten (10) days after the receipt of such documentation and other
information, Lessor shall (1) notify Lessee in writing that Lessor elects to consent to the proposed assignment or sublease subject to the terms and conditions hereinafter set forth; or
(2) notify Lessee in writing that Lessor refuses such consent, specifying reasonable grounds for such refusal; or (3) subject to the provisions set forth below, notify Lessee that Lessor
elects to terminate this Lease and specifying the effective date of termination. Upon the effective date of termination Lessor and Lessee shall each be released and discharged from any liability or
obligation to the other under this Lease accruing thereafter, and Lessee agrees that Lessor may enter into a direct lease with such proposed assignee or sublessee without any obligation or liability
to Lessee. Notwithstanding the foregoing, Lessor shall only have the right to terminate this Lease pursuant to the foregoing clause (3) in the event of a proposed assignment by Lessee of its
entire right, title and interest under this Lease, or in the event of a
proposed sublease by Lessee of the entire Premises for the then remaining term of this Lease, or for the then remaining term except for the final thirty (30) days or less thereof, provided that
in no event shall Lessor have any right to terminate this Lease in connection with any transfer permitted under Paragraph 16(h). In addition, if Lessor notifies Lessee pursuant to the foregoing
clause (3) that Lessor elects to terminate this Lease, Lessee shall have the right to rescind its proposed assignment or sublease by giving written notice thereof to Lessor, in which event this
Lease shall remain in full force and effect as if Lessee had never proposed such assignment or sublease. 

        (c)   In
deciding whether to consent to any proposed assignment or sublease, Lessor may take into account whether or not reasonable conditions have been satisfied, including,
but not limited to, the following: 

        (1)   In
Lessor's reasonable judgment, the proposed assignee or subtenant is engaged in such a business, that the Premises, or the relevant part thereof, will be used in such
a manner which complies with Paragraph 7 hereof entitled "Use" and Lessee or the proposed assignee or sublessee submits to Lessor documentary evidence reasonably satisfactory to Lessor that
such proposed use constitutes a permitted use of the Premises pursuant to the ordinances and regulations of the City of Palo Alto; 

        (2)   The
proposed assignee or subtenant shall be a reputable entity or individual with sufficient financial net worth so as to reasonably indicate that it will be able to
meet its obligations under this Lease or the sublease in a timely manner; 

        (3)   The
proposed assignment or sublease shall be subject to approval by Lessor's mortgage lender, if any, if such lender has the right to approve or disapprove proposed
assignments or subleases; 

        (4)   The
proposed assignment or sublease shall expressly prohibit further assignment or subletting of all or any part of the Premises by the assignee or sublessee; and 

        (5)   Lessor's
consent to the assignment or sublease shall be in a separate instrument containing the relevant provisions of this Paragraph 16 and otherwise in form
reasonably acceptable to Lessor and its counsel. 

        (d)   As
a condition to Lessor's granting its consent to any assignment or sublease, (1) Lessor may require that Lessee pay to Lessor, as and when received by Lessee,
fifty percent (50%) of the amount of any excess of the consideration to be received by Lessee in connection with said assignment or sublease over and above the rental amount fixed by this Lease and
payable by Lessee to Lessor, after deducting only reasonable leasing commissions, reasonable attorneys' fees, and other reasonable costs and expenses incurred by Lessee in consummating such assignment
or sublease which are approved in writing by Lessor; and (2) Lessee and the proposed assignee or sublessee shall demonstrate to Lessor's reasonable satisfaction that each of the criteria
referred to in subparagraph (c) above is satisfied. 

14

 

 

        (e)   Each
assignment or sublease agreement to which Lessor has consented shall be an instrument in writing which complies with the provisions of this Paragraph 16 and
in form reasonably satisfactory to Lessor, and shall be executed by both Lessee and the assignee or sublessee, as the case may be. Each such assignment or sublease agreement shall recite that it is
and shall be subject and subordinate to the provisions of this Lease, that the assignee or sublessee accepts such assignment or sublease, that Lessor's consent thereto shall not constitute a consent
to any subsequent assignment or subletting by Lessee or the assignee or sublessee, and, except as otherwise set forth in a sublease approved by Lessor, agrees to perform all of the obligations of
Lessee hereunder (to the extent such obligations relate to the portion of the Premises assigned or subleased), and that the termination of this Lease shall, at Lessor's sole election, constitute a
termination of every such assignment or sublease. 

        (f)    In
the event Lessor shall consent to an assignment or sublease, Lessee shall, except as otherwise provided in Paragraph 16(h), remain primarily liable for all
obligations and liabilities of Lessee under this Lease, including, but not limited to, the payment of rent. 

        (g)   Lessee
hereby stipulates that the foregoing terms and conditions are reasonable and comply with the California Civil Code Section 1951.4. 

        (h)   Notwithstanding
the foregoing, Lessee may, without Lessor's prior written consent, without Lessor having the right pursuant to Paragraph 16(b) above to terminate
this Lease, and without any participation by Lessor in assignment and subletting proceeds, assign this Lease or sublet all or any portion of the Premises to a parent, subsidiary, affiliate, division
or corporation controlled or under common control with Lessee ("Permitted Affiliate"), or to a successor corporation to Lessee by merger, consolidation or reorganization, or to any entity which
acquires all or substantially all of the assets or capital stock of Lessee, provided, that except as specified hereafter, AnaMax, Inc. shall remain primarily liable for all obligations and
liabilities of Lessee under this Lease, including, but not limited to, the payment of rent. Lessee's foregoing rights to assign this Lease or to sublet the Premises shall be subject to the following
conditions: (1) there shall be no uncured Event of Default by Lessee under this Lease; (2) in the case of an assignment or subletting to a Permitted Affiliate, AnaMax, Inc. shall
remain liable to Lessor hereunder, unless as a result of a merger, consolidation, or reorganization AnaMax, Inc. is not
a surviving entity, and in such event the transferee or successor entity to AnaMax, Inc. shall have on the effective date of such transaction a net worth as shown on its current balance sheet
certified by a major independent certified public accounting firm equal to at least the net worth of AnaMax, Inc. as of the date immediately prior to the effective date of such transaction; and
(3) the transferee or successor entity shall expressly assume in writing Lessee's obligations hereunder accruing from and after the effective date of such assignment or subletting. 

        (i)    The
sale or transfer of Lessee's capital stock in a public offering pursuant to an effective registration statement filed by Lessee with the Securities and Exchange
Commission shall not be deemed an assignment, subletting, or other transfer of this Lease or the Premises. 

        (j)    Subject
to the provisions of this Paragraph 16 any assignment or sublease without Lessor's prior written consent shall at Lessor's election be void. The consent
by Lessor to any assignment or sublease shall not constitute a waiver of the provisions of this Paragraph 16, including the requirement of Lessor's prior written consent, with respect to any
subsequent assignment or sublease. If Lessee shall purport to assign this Lease, or sublease all or any portion of the Premises, without Lessor's prior written consent (if such consent is required
hereunder), Lessor may collect rent from the person or persons then or thereafter occupying the Premises and apply the net amount collected to the rent reserved herein, but no such collection shall be
deemed a waiver of Lessor's rights and remedies under this Paragraph 16, or the acceptance of any such 

15

 

purported
assignee, sublessee, or occupant, or a release of Lessee from the further performance by Lessee of covenants on the part of Lessee herein contained. 

        (k)   Lessee
shall not hypothecate or encumber its interest under this Lease or any rights of Lessee hereunder, or enter into any license or concession agreement respecting
all or any portion of the Premises, without Lessor's prior written consent which shall not be unreasonably withheld, subject to all of the provisions of this Paragraph 16. 

        (l)    In
the event of any sale or exchange of the Premises by Lessor and assignment of this Lease by Lessor, Lessor shall, upon providing Lessee with written confirmation by
Lessor's successor in interest to the Premises that Lessor has delivered any security deposit held by Lessor to Lessor's successor in interest, be and hereby is entirely relieved of all liability
under any and all of Lessor's covenants and obligations contained in or derived from this Lease with respect to the period commencing with the consummation of the sale or exchange and assignment. 

        (m)  The
parties acknowledge that Lessor has the remedy described in California Civil Code Section 1951.4 (Lessor may continue the Lease in effect after Lessee's
breach and abandonment and recover rent as it becomes due, if Lessee has right to sublet or assign, subject only to reasonable limitations). 

        17.    Waiver.    The waiver by Lessor or Lessee of any breach of any term, covenant, or condition contained herein
shall not be deemed to be a waiver of such term, covenant, or condition of any subsequent breach of the same or any other term, covenant, or condition contained herein. The subsequent acceptance of
rent hereunder by Lessor shall not be deemed to be a waiver of any preceding breach by Lessee of any term, covenant, or condition of this Lease, other than the failure of Lessee to pay the particular
rent so accepted, regardless of Lessor's knowledge of such preceding breach at the time of acceptance of such rent. 

        18.    Holding Over.    Lessee shall vacate the Premises and deliver the same to Lessor in the condition required by
this Lease upon the expiration or sooner termination of this Lease. In the event of holding over by Lessee after the expiration or termination of this Lease, such holding over shall be on a
month-to-month tenancy and all of the terms and provisions of this Lease shall be applicable during such period, except that Lessee shall pay Lessor as Monthly Base Rent during
such holdover an amount equal to the greater of (1) one hundred fifty percent (150%) of the Monthly Base Rent in effect at the expiration of the term, or (2) the then market rent for
comparable research and development/office space. If such holdover is without Lessor's written consent, Lessee shall be liable to Lessor for all costs and expenses incurred by Lessor as a result of
such holdover. The rental payable during such holdover period shall be payable to Lessor on demand. 

        19.    Damage or Destruction.    

        (a)   In
the event of a total destruction of the Building and Improvements during the Lease term from any cause, either party may elect to terminate this Lease by giving
written notice of termination to the other party within thirty (30) days after the casualty occurs. A total destruction shall be deemed to have occurred for this purpose if the Building and
Improvements of the Premises are destroyed to the extent of seventy-five percent (75%) or more of the full replacement cost thereof or requires the Lessee to relocate ("Relocate") a
substantial amount of its chemistry and biology laboratories or animal facility for more than 30 days. If the Building and Improvements are destroyed to the extent of seventy-five
percent (75%) or more of the full replacement cost or Lessee is required to Relocate and this Lease is not terminated by either Lessor or Lessee, Lessor shall, provided that Lessor receives sufficient
insurance proceeds, repair and restore the Building and Improvements to substantially the condition existing as of the Commencement Date of this Lease in a diligent manner and this Lease shall
continue in full force and effect, except that Monthly Base Rent shall be abated in accordance with Paragraph 19(f) 

16

 

below.
Lessee at its election may, but shall not be obligated to, repair and restore the balance of the Building and Improvements at Lessee's expense, including any leasehold improvements constructed
by Lessee during the term of this Lease, or Lessee may elect to terminate this Lease within thirty (30) days of being informed by Lessor that due to the shortfall in insurance proceeds, Lessor
is only partially rebuilding the Premises. 

        (b)   In
the event of a partial destruction of the Building and Improvements to the Premises to an extent exceeding ten percent (10%), but less than seventy-five
percent (75%) of the full replacement cost thereof, Lessee is not required to Relocate, and provided that the damage can be repaired, reconstructed or restored within one hundred fifty
(150) days after the date of the casualty, Lessor shall have the right at Lessor's option either (1) to repair and restore the Building and Improvements, in which event this Lease shall
continue in full force and effect, except that the Monthly Base Rent shall be abated in accordance with the last sentence of Paragraph 19(f) below, or (2) to terminate this Lease by
giving written notice of termination to Lessee within thirty (30) days after the casualty, subject to the provisions of Paragraph 19(e) below. Lessor's election to repair and restore the
Building and Improvements, or to terminate this Lease, shall be made and written notice thereof shall be given to Lessee within thirty (30) days after the casualty. If Lessor elects to restore,
Lessor's obligation shall be to repair and restore the Building and Improvements to substantially the condition existing as of the Commencement Date not later than 150 days after the date of
the casualty and Lessee shall repair and restore the balance of the Building and Improvements at Lessee's expense, including any Improvements constructed by Lessee during the term of this Lease.
Notwithstanding any provision herein to the contrary, if the casualty occurs in the last twelve (12) months of the term, or if the restoration of the Premises is not expected to be completed
prior to nine (9) months before the Termination Date, either Lessor or Lessee shall have the right to terminate this Lease upon written notice to the other party to be given not more than
thirty (30) days after the date of the casualty, provided, however, that Lessor shall not have such right to terminate if Lessee agrees, in Lessee's discretion, by written notice to Lessor
given within ten (10) days after receipt by Lessee of Lessor's notice of termination, to pay the cost of restoring the Premises to their condition immediately prior to the casualty, less the
amount of the insurance proceeds received by Lessor, if any, on account of the casualty. 

        (c)   If
the Building and the Improvements to the Premises are damaged to an extent exceeding ten percent (10%), but less than seventy-five percent (75%) of the
full replacement cost thereof, but the damage cannot be repaired, reconstructed, or restored within a period of one hundred fifty (150) days after the date of the casualty, either Lessor or
Lessee may terminate this Lease by giving written notice of termination to the other within thirty (30) days after the casualty. 

        (d)   Lessor
shall not have the right to terminate this Lease if (1) the repair or restoration would cost less than ten percent (10%) of the full replacement cost of
the Building, or (2) the cost of the repair or restoration would exceed ten percent (10%) of the full replacement cost, but Lessee agrees to pay the cost of repair in excess of ten percent
(10%) of the full replacement cost and Lessee delivers said sum to Lessor within ten (10) business days after receipt of a written request therefor from Lessor. Any funds contributed by Lessee
for the cost of repair or restoration shall be deposited by Lessor into a separate trust account. Lessee shall have the right to approve all disbursements from said account, which approval shall not
be unreasonably withheld or denied. 

        (e)   Lessor's
obligation to repair and restore the Premises pursuant to the foregoing provisions shall be limited to the improvements existing as of the Commencement Date of
the term of this Lease. Lessee at its option may, but shall not be required to, repair or replace, at Lessee's expense, all leasehold improvements, fixtures, and equipment installed by either Lessor
or Lessee after the date of this Lease. If this Lease is not terminated by Lessor or Lessee pursuant to the foregoing provisions, Lessor shall complete the repairs in a diligent manner and this Lease
shall continue in full force and effect, except that Monthly Base Rent shall be abated in 

17

 

accordance
with Paragraph 19(f) below. Lessor's time for completion of the repairs and restoration of the Premises shall be extended by a period equal to any delays caused by strikes, labor
disputes, unavailability of materials, inclement weather, acts of God, or other causes beyond Lessor's control. 

        (f)    In
the event of repair, reconstruction, or restoration as provided herein, the Monthly Base Rent and Additional Rent shall be abated proportionally in the ratio which
the Lessee's use of the Premises is impaired during the period of such repair, reconstruction, or restoration. In the event of termination of this Lease pursuant to any of the provisions of this
Paragraph 19, the Monthly Base Rent shall be apportioned on a per diem basis and shall be paid to the date of the casualty. In no event shall Lessor be liable to Lessee for any damages
resulting to Lessee from the occurrence of such casualty, or from the repairing or restoration of the Building and Improvements, or from the termination of this Lease as provided herein, nor shall
Lessee be relieved thereby from any of Lessee's obligations hereunder, except to the extent and upon the conditions expressly set forth in this Paragraph 19. 

        (g)   The
parties waive their rights under applicable law to the extent inconsistent with the foregoing provisions. 

        20.    Eminent Domain.    

        (a)   If
the whole or any substantial part of the Building shall be taken or condemned by any competent public authority for any public use or purpose, the term of this Lease
shall end upon the earlier to occur of the date when the possession of the part so taken shall be required for such use or purpose or the vesting of title in such public authority. Rent shall be
apportioned as of the date of such termination. Lessee shall be entitled to receive any damages separately awarded by the court for (1) leasehold improvements installed at Lessee's expense or
other property owned by Lessee, (2) reasonable costs of moving by Lessee to another location as agreed upon by Lessee in Santa Clara County or San Mateo County, California, and (3) any
portion of the award made to compensate loss of Lessee's business. The entire balance of the award shall be the property of Lessor. 

        (b)   If
there is a partial taking of the Premises by eminent domain which is not a substantial part of the Building and the balance of the Premises remains reasonably
suitable for continued use and occupancy by Lessee for the purposes referred to in Paragraph 7, Lessor shall complete any necessary repairs in a
diligent manner and this Lease shall remain in full force and effect with a just and proportionate abatement of the Monthly Base Rent and Additional Rent, to reflect the number of square feet of the
Building taken and the number of square feet remaining. If after a partial taking, the Premises are not reasonably suitable for Lessee's continued use and occupancy for the uses permitted herein,
Lessee may terminate this Lease effective on the earlier of the date title vests in the public authority or the date possession is taken. Subject to Lessee's entitlement to receive any damages
separately awarded to Lessee by the court as set forth in Paragraph 20(a), the entire award for such taking shall be the property of Lessor. 

        21.    Remedies.    If Lessee fails to make any payment of rent or any other sum due under this Lease for five
(5) days or more after receipt by Lessee of written notice from Lessor; or if Lessee breaches any other term of this Lease for thirty (30) days or more after receipt by Lessee of written
notice from Lessor (unless such default is reasonably incapable of cure within thirty (30) days and Lessee commences cure within thirty (30) days and diligently prosecutes the cure to
completion within a reasonable time); or if Lessee's interest herein, or any part thereof, is assigned or transferred, either voluntarily or by operation of law (except as expressly permitted by other
provisions of this Lease); or if Lessee makes a general assignment for the benefit of its creditors; or if this Lease is rejected (1) by a bankruptcy trustee for Lessee, (2) by Lessee as
debtor in possession, or (3) by failure of Lessee as a bankrupt debtor to act timely in assuming or rejecting this Lease; then any of such events shall 

18

 

constitute
an event of default and breach of this Lease by Lessee and Lessor may, at its option, elect the remedies specified in either subparagraph (a) or (b) below. Any such rejection
of this Lease referred to above shall not cause an automatic termination of this Lease. Whenever in this Lease reference is made to a default by Lessee, such reference shall refer to an event of
default ("Event of Default") by Lessee as defined in this Paragraph 21. 

        (a)   Lessor
may repossess the Premises and remove all persons and property therefrom. If Lessor repossesses the Premises because of an Event of Default by Lessee, this Lease
shall terminate and Lessor may recover from Lessee: 

        (1)   the
worth at the time of award of the unpaid rent which had been earned at the time of termination including interest thereon at a rate equal to the Federal discount
rate plus one percent (1%), or the maximum legal rate of interest, whichever is less, from the time of termination until paid; 

        (2)   the
worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such
rental loss that Lessee proves could have been reasonably avoided, including interest thereon at a rate equal to the Federal discount rate plus one percent (1%) per annum, or the maximum legal rate of
interest, whichever is less, from the time of termination until paid; 

        (3)   the
worth at the time of award of the amount by which the unpaid rent for the balance of the term after the time of award exceeds the amount of such rental loss for the
same period that Lessee proves could be reasonably avoided, discounted at the discount rate published by the Federal Reserve Bank of San Francisco for member banks at the time of award plus one
percent (1%); and 

        (4)   any
other amount necessary to compensate Lessor for all the detriment proximately caused by Lessee's breach or by Lessee's failure to perform its obligations under this
Lease or which in the ordinary course of things would be likely to result therefrom.

        25.    Signage.    Lessee shall have the right to erect at Lessee's expense a standard monument sign in an appropriate
location on the Premises designated by Lessor, subject to Lessee obtaining necessary City approvals and subject to the compliance of Lessee's monument sign with applicable City ordinances and

20

 

  
        26.    Real Estate Brokers.    Subject to the execution and delivery of this Lease by the parties, Lessor shall pay
a
leasing commission to Cornish & Carey Commercial, the procuring broker, and to CPS, a Commercial Real Estate Company, Inc. ("CPS"), Lessor's agent, pursuant to separate agreements
between Lessor and said brokers. Lessor and Lessee each represents to the other that it has not had any dealings with any real estate broker, finder, or other person with respect to this Lease other
than Cornish & Carey Commercial and CPS, and each party shall indemnify, defend, and hold harmless the other party from all damages, expenses, and liabilities resulting from any claims that may
be asserted against the other party by any broker, finder, or other person with whom the indemnifying party has or purportedly has dealt other than Cornish & Carey Commercial and CPS. 

        27.    Subordination; Attornment.    The Premises are currently free and clear of any mortgage. At least thirty
(30) days prior to placing any mortgage loan on the Premises Lessor shall deliver to Lessee the form of Subordination, Non-Disturbance and Attornment Agreement approved by Lessor's
mortgage lender and Lessor ("Lessor's SNDA"). Lessee shall execute and deliver to Lessor Lessor's SNDA, with such changes as are reasonably requested by Lessee and approved by Lessor and Lessor's
lender. 

        28.    Breach by Lessor.    

        (a)   Lessor
shall not be deemed in breach of this Lease unless Lessor fails within a reasonable time to perform an obligation required to be performed by Lessor pursuant to
this Lease. For purposes of this Paragraph 28, a reasonable time shall in no event be less then thirty (30) days after receipt by Lessor, and by the holders of any mortgage or deed of
trust covering the Premises whose name and address have been furnished to Lessee in writing for such purposes, of written notice specifying wherein such obligation of Lessor has not been performed;
provided, however, that if the nature of Lessor's obligation is such that more than thirty (30) days after such notice are reasonably required for its performance, then Lessor shall not be in
breach of this Lease if performance is commenced within such thirty (30) day period and thereafter diligently pursued to completion. 

        (b)   In
the event of a breach of this Lease by Lessor, unless otherwise set forth herein, Lessee's sole remedy shall be to institute an action against Lessor for damages or
for equitable relief, but Lessee shall not have the right to rent abatement other than as set forth herein, to offset against rent, or to terminate this Lease. Lessee expressly waives the defense of
constructive eviction. If Lessor has not performed any obligation hereunder or any warranty made by Lessor herein proves to be untrue, Lessee shall give Lessor written notice thereof, whereupon Lessee
shall have the right, after giving Lessor a reasonable opportunity to cure in light of the circumstances, to take such corrective action as is reasonably necessary to preserve the integrity of
Lessee's laboratory equipment, research, and experimentation and the health and safety of Lessee's employees and its laboratory animals. Lessor shall reimburse Lessee for any costs or expenses Lessee
incurs in performing such corrective and preventive action, but Lessee shall not have the right to rent abatement, to offset against rent, or to terminate this Lease on account thereof. 

        29.    Approvals.    Notwithstanding anything to the contrary in this Lease, whenever this Lease requires an approval,
consent, designation, determination, or judgment by either Lessor or Lessee, such approval, consent, designation, determination, or judgment (including, without limiting the generality of the
foregoing, those required in connection with assignment and subletting) shall not be unreasonably withheld or delayed and in exercising any right or remedy hereunder, each party shall at all times act
reasonably and in good faith. 

        30.    Lessor's Entry.    Except in the case of an emergency and except for permitted entry if necessary to complete
Lessor's initial tenant improvement work pursuant to Paragraph 12(a) and Paragraph 12(b), or otherwise during Lessee's normal working hours, Lessor and Lessor's agents shall provide
Lessee with at least twenty-four (24) hours' notice prior to entry of the Premises. Such entry by 

21

 

Lessor
and Lessor's agents shall not interfere with Lessee's operations more than reasonably necessary. Lessor and Lessor's agents shall at all times be accompanied by Lessee during any such entry
except in case of emergency. Lessor may enter the Premises without prior notice to Lessee if Lessee has vacated the Premises. 

        31.    Attorneys' Fees.    If any action at law or in equity shall be brought to recover any rent under this Lease, or
for or on account of any breach of or to enforce or interpret any of the provisions of this Lease or for recovery of the possession of the Premises, the prevailing party shall be entitled to recover
from the other party costs of suit and reasonable attorneys' fees, the amount of which shall be fixed by the court and shall be made a part of any judgment rendered. 

        32.    Compliance with CC&Rs.    Lessor warrants that there are no covenants, conditions, and restrictions affecting
the Premises ("CC&Rs") in effect as of the date of this Lease. Lessor agrees that during the term of this Lease Lessor will not without Lessee's prior written consent allow or adopt any CC&Rs that
would have the effect of prohibiting Lessee from undertaking the Permitted Uses or require
Lessee to make alterations or improvements to the Premises to comply with such CC&Rs in order for Lessee to continue to undertake the Permitted Uses. 

        33.    Quiet Possession.    So long as no Event of Default by Lessee exists under this Lease, Lessee shall have quiet
enjoyment and possession of the Premises for the entire term hereof subject to all of the provisions of this Lease. 

        34.    General Provisions.    

        (a)   Nothing
contained in this Lease shall be deemed or construed by the parties hereto or by any third person to create the relationship of principal and agent or of
partnership or of joint venture of any association between Lessor and Lessee, and neither the method of computation of rent nor any other provisions contained in this Lease nor any acts of the parties
hereto shall be deemed to create any relationship between Lessor and Lessee other than the relationship of landlord and tenant. 

        (b)   Each
and all of the provisions of this Lease shall be binding upon and inure to the benefit of the parties hereto, and except as otherwise specifically provided
elsewhere in this Lease, their respective heirs, executors, administrators, successors, and assigns, subject at all times, nevertheless, to all agreements and restrictions contained elsewhere in this
Lease with respect to the assignment, transfer, encumbering, or subletting of all or any part of Lessee's interest in this Lease. 

        (c)   The
captions of the paragraphs of this Lease are for convenience only and shall not be considered or referred to in resolving questions of interpretation or
construction. 

        (d)   This
Lease is and shall be considered to be the only agreement between the parties hereto and their representatives and agents. All negotiations and oral agreements
acceptable to both parties have been merged into and are included herein. There are no other representations or warranties between the parties and all reliance with respect to representations is
solely upon the representations and agreements contained in this instrument. 

        (e)   The
laws of the State of California shall govern the validity, performance, and enforcement of this Lease. Notwithstanding which of the parties may be deemed to have
prepared this Lease, this Lease shall not be interpreted either for or against Lessor or Lessee, but this Lease shall be interpreted in accordance with the general tenor of the language in an effort
to reach an equitable result. 

        (f)    Time
is of the essence with respect to the performance of each of the covenants and agreements contained in this Lease. 

22

 

        (g)   Recourse
by Lessee for breach of this Lease by Lessor shall be expressly limited to the greater of: (1) Lessor's interest in the Premises and the rents, issues
and profits therefrom, or (2) three million dollars ($3,000,000), and in the event of any such breach or default by Lessor Lessee hereby waives the right to proceed against any other assets of
Lessor or against any other assets of any manager or member of Lessor. 

        (h)   Any
provision or provisions of this Lease which shall be found to be invalid, void or illegal by a court of competent jurisdiction, shall in no way affect, impair, or
invalidate any other provisions hereof, and the remaining provisions hereof shall nevertheless remain in full force and effect. 

        (i)    This
Lease may be modified in writing only, signed by the parties in interest at the time of such modification. 

        (j)    Each
party represents to the other that the persons signing this Lease on its behalf are properly authorized to do so. Upon the request of either party, evidence of the
written authority of such persons to sign on behalf of the other party shall be provided to the requesting party hereto either prior to or simultaneously with the return to the requesting party of a
fully executed copy of this Lease. 

        (k)   No
binding agreement between the parties with respect to the Premises shall arise or become effective until this Lease has been duly executed by both Lessee and Lessor
and a fully executed copy of this Lease has been delivered to both Lessee and Lessor. 

        (l)    Lessor
and Lessee acknowledge that the terms and conditions of this Lease constitute confidential information of Lessor and Lessee. Neither party shall disseminate
orally or in written form a copy of this Lease, lease proposals, lease drafts, or other documentation containing the terms, details or conditions contained herein to any third party without
obtaining the prior written consent of the other party, except to the attorneys, accountants, or other authorized business representatives or agents of the parties, or to the extent required to comply
with applicable Laws. 

        (m)  Subject
to the provisions of Paragraph 28, the rights and remedies that either party may have under this Lease or at law or in equity, upon any breach, are
distinct, separate and cumulative and shall not be deemed inconsistent with each other, and no one of them shall be deemed to be exclusive of any other. 

        (n)   Lessor
and Lessee waive any claim for consequential damages which one may have against the other for breach of or failure to perform or observe the requirements and
obligations created by this Lease. 

        (o)   Lessor
and Lessee each agree to and they hereby do waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the
other on any matters whatsoever arising out of or in any way connected with this Lease, the relationship of Lessor and Lessee, Lessee's use or occupancy of the Premises and/or any claim of injury or
damage, and any statutory remedy. 

        (p)   This
Lease shall not be recorded. 

23

 

        IN
WITNESS WHEREOF, the Lessor and Lessee have duly executed this Lease as of the date first set forth herein.

        2.    Initial Term.    The first sentence of Paragraph 2(a) of the Lease, as amended by the First Amendment, is
further amended to read as follows: 

        "(a)
The initial term of the Lease commenced on January 1, 2003 (the "Commencement Date"), and shall expire on December 31, 2006 (the "Expiration Date"), unless sooner

        The

	Period

 
	 	Rent/SF/Mo./NNN 	 	Amount 	 
	 January 1, 2003 - December 31, 2003
	 	$	1.75	 	$	26,775	 
	 January 1, 2004 - December 31, 2004
	 	$	1.80	 	$	27,540	 
	 January 1, 2005 - December 31, 2006
	 	$	1.85	 	$	28,305	 

 

 

Monthly
Base Rent shall be payable on a NNN basis and shall be payable by Lessee to Lessor in accordance with Paragraph 5 hereof." 

 

        4.    Option to Extend.    The Lease is amended by adding thereto a new Paragraph 35, Option to Extend, which
shall to read as follows: 

        "35.    Option to Extend.    

        (a)   Lessor
hereby grants to Lessee one (1) option to extend the term of this Lease for one (1) period of twenty-four (24) calendar months
immediately following the expiration of the initial term. Lessee may exercise the foregoing option to extend by giving written notice of exercise to Lessor at least three (3) months, but not
more than nine (9) months, prior to the expiration of the initial term of this Lease, time being of the essence; provided that if Lessee is currently in a state of uncured default
after the expiration of applicable notice and cure periods (referred to herein as "in default") under this Lease at the time of exercise of the option or at the commencement date of the option
extension period, such notice shall be void and of no force or effect. Such option extension period, if exercised, shall be upon the same terms and conditions as the initial term of this Lease,
including the payment by Lessee of the Operating Expenses of the Premises in accordance with Paragraph 4(b) of the Lease and the real property taxes and assessments in accordance with
Paragraph 4(c) of the Lease, except that (1) the Monthly Base Rent during the option period shall be determined as set forth in Paragraph 35(b) hereof, (2) there shall be
no additional option to extend, and (3) Lessee shall accept the Premises on the commencement date of the option extension period in their then "as is" condition. If Lessee does not exercise the
option in a timely manner the option shall lapse, time being of the essence. 

        (b)   The
initial Monthly Base Rent for the Premises during the option extension period shall be determined pursuant to the provisions of this subparagraph (b) and,
subject to subparagraph (d) below, shall equal one hundred percent (100%) of the then current fair market rental for the Premises as of the commencement date of the option extension period
(hereafter, the "current fair market rental") as determined by agreement between the Lessor and Lessee, if possible, and by the process of appraisal if the parties cannot reach agreement. 

        If
Lessor and Lessee are unable to agree upon the current fair market rental for the Premises, the appraisal shall be performed by one appraiser if the parties are able to agree upon one
appraiser. If the parties are unable to agree upon one appraiser, each party shall appoint an appraiser and the two appraisers shall select a third appraiser. Each appraiser selected shall be a member
of the American Institute of Real Estate Appraisers (AIREA) with at least five (5) years of full-time commercial real estate appraisal experience in the Palo Alto research and
development rental market. 

        If
only one appraiser is selected, that appraiser shall notify the parties in simple letter form of its determination of the current fair market rental for the Premises within fifteen
(15) days following its selection. Said appraisal shall be binding on the parties as the appraised "current fair market rental" for the Premises which shall be based upon the then current
rental paid by tenants for premises in the vicinity of the Premises of similar age, size, quality of construction and specifications, but excluding the value, if any, as of the commencement date of
the option extension period of any improvements constructed in the Premises at Lessee's expense either at the commencement of the initial term or thereafter during the initial term with Lessor's prior
written consent (the "comparable buildings"). If multiple appraisers are selected, each appraiser shall within ten (10) days of being selected make its determination of the current fair market
rental for the Premises in simple letter form. If two (2) or more of the appraisers agree on the rent for the Premises, such agreement shall be binding upon the parties. If multiple appraisers
are selected and two (2) appraisers are unable to agree on the current fair market rental, the current fair market rental for the Premises shall be determined by taking the mean average of the
appraisals; provided, that any high or 

2

 

low
appraisal, differing from the middle appraisal by more than ten percent (10%) of the middle appraisal, shall be disregarded in calculating the average. The appraiser or appraisers may also provide
for an adjustment of the initial current fair market rental during the option extension period if such
adjustment is consistent with the then market practice, subject to the limitation in subparagraph (d) below. 

        If
only one appraiser is selected, then each party shall pay one-half of the fees and expenses of that appraiser. If three appraisers are selected, each party shall bear the
fees and expenses of the appraiser it selects and one-half of the fees and expenses of the third appraiser. 

        (c)   Thereafter,
provided that Lessee has previously given timely notice to Lessor of the exercise by Lessee of the option to extend the term, Lessor and Lessee shall execute
an amendment to this Lease stating that the initial Monthly Base Rent for the Premises during the option extension period shall be equal to the current fair market rental as determined by appraisal,
with any adjustment specified by the appraiser or appraisers, subject to subparagraph (d) below. 

        (d)   Notwithstanding
anything to the contrary contained in subparagraph (b) above, in no event shall the Monthly Base Rent at the commencement of the option extension
period be less than $1.85 per rentable square foot NNN, the Monthly Base Rent in effect immediately prior to the commencement of the option extension period, and in no event shall the Monthly Base
Rent at the commencement of the option extension period, as determined by agreement of the parties or as determined by appraisal if the parties do not agree, increase in total by more than $0.10 per
rentable square foot during the option extension period. 

        (e)   If
Lessee exercises the option to extend, Lessor hereby grants to Lessee the option to terminate this Lease at any time during the option extension period by giving at
least six (6) months' prior written notice of termination to Lessor. If Lessee exercises such termination right, Lessee shall pay all rent due and perform all of Lessee's other obligations
hereunder through the effective date of termination. Monthly Base Rent and Additional Rent shall be prorated as of the effective date of termination." 

        5.    Continuing Effect.    Except as amended hereby, the Lease shall remain in full force and effect. 

        6.    Counterparts.    This Amendment may be executed in counterparts, each of which shall be deemed an original, but
all of which together shall constitute one and the same instrument. 

3

 

        IN
WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed, as of the date first above written.

Palo Alto, California  

        THIS THIRD AMENDMENT TO LEASE (this "Amendment"), dated for reference purposes as of September 23, 2008, is made and entered

and sufficiency of which are hereby acknowledged, the parties agree as follows:

        "35.    Option to Extend.    

        (a)   Lessor
hereby grants to Lessee two (2) consecutive options to extend the term of this Lease for a period of twelve (12) calendar months each, with the
first option to extend, if timely exercised, commencing immediately following the Expiration Date of the initial term, and with the second option to extend, if timely exercised, commencing immediately

hereof, (2) there shall be no additional option to extend, and (3) Lessee shall accept the Premises on the commencement date of each option extension period in their then "as is"
condition, subject to any continuing repair and maintenance obligations of Lessor. If Lessee does not exercise an option in a timely manner, such option and the succeeding option, if applicable, shall
automatically lapse, time being of the essence. The "lease term," as used in this Lease shall include the initial term and the option period(s), if exercised. 

        (b)   Lessee
shall pay to Lessor during the option periods, if exercised, Monthly Base Rent as follows: 

 

 

								
	Period

 
	 	Rent/SF/Mo./NNN 	 	Amount 	 
	 January 1, 2010—December 31, 2010
	 	$	2.05	 	$	31,365	 
	 January 1, 2011—December 31, 2011
	 	$	2.15	 	$	32,895	 

 

 

        (c)   The
options to extend granted to Lessee by this Paragraph 35 are granted for the personal benefit of Anacor Pharmaceuticals, Inc. ("Anacor") only, and
shall be exercisable only by Anacor or by a "Permitted Affiliate" under Paragraph 16(h). Said options may not be assigned or transferred by Anacor to any assignee or sublessee other than a
Permitted Affiliate." 

        (d)   If
Lessee exercises either or both of the options to extend, Lessor hereby grants to Lessee the option to terminate this Lease at any time during either of the option
extension periods by giving prior written notice of termination to Lessor, provided that the effective date of termination shall be not less than four (4) months after the receipt by Lessor of
the written notice of termination. If Lessee exercises such termination right, Lessee shall pay all rent due and perform all of Lessee's other obligations hereunder through the effective date of
termination. Monthly Base Rent and Additional Rent shall be prorated as of the effective date of Termination."
