EMPLOYMENT BY THE COMPANY

Subject to the terms set forth herein,
the Company agrees to employ Executive in the position of Executive Vice
President, General Counsel and Corporate Secretary, such employment to commence
on the Commencement Date. During the Executive’s employment, Executive will
report to the Chief Executive Officer. Executive shall serve in a part-time
employee capacity equivalent to eighty percent (80%) of a full time work
schedule and shall perform such duties as are assigned to Executive by the Chief
Executive Officer and, except as otherwise instructed by the Chief Executive
Officer, such other duties as are customarily associated with the position of
General Counsel and Secretary. The part-time schedule will be annually
re-evaluated by the Company to ensure that the arrangement meets the needs of
the Company. During Executive’s employment with the Company, Executive will
devote Executive’s best efforts and substantially all of Executive’s business
time and attention (except for vacation periods as set forth herein and
reasonable periods of illness or other incapacities permitted by the Company’s
general employment policies or as otherwise set forth in this Agreement) to the
business of the Company.

     2.2 Employment at Will.
Both the Company and Executive
acknowledge and agree that Executive’s employment with the Company is “at-will”
and not for any specified period of time, and may be terminated at any time by
Executive or the Company, with or without Cause, and with or without prior
notice; provided, however, that if Executive’s employment with the Company is
terminated under circumstances that constitute a Covered Termination, Executive
will be eligible to receive certain severance payments and benefits as set forth
in Article IV below.

2

     2.3 Employment
Policies. The employment relationship
between the parties shall also be governed by the general employment policies
and practices of the Company, including but not limited to those policies
relating to protection of confidential information and assignment of inventions.
In the event of a conflict between the terms of this Agreement and the Company’s
general employment policies or practices, this Agreement shall
control.

ARTICLE III
COMPENSATION

     3.1 Base
Salary. Executive shall receive for
services to be rendered hereunder an annual base salary of $292,000 which has
been pro-rated to reflect eighty percent (80%) of a full time work schedule. The
Base Salary is payable on the regular payroll dates of the Company subject to
increase in the sole discretion of the Board (the “Base Salary”). 

     3.2 Bonus. Executive shall be eligible to earn, for each fiscal year of
the Company ending during Executive’s employment with the Company, an annual
discretionary cash bonus (an “Annual
Bonus”) targeted at forty five percent (45%)
of Executive’s Base Salary.

     3.3
Stock Option. The Compensation Committee of the Board granted Executive an option to purchase four hundred and twenty-five
thousand (425,000) shares of Company common stock (the “Option”) on February 16, 2012 (the “Grant Date”),
having an exercise price equal to the closing trading price of a share of Company common stock on the Grant Date. The Option shall
vest with respect to 1/8th of the shares initially subject thereto on the six-month anniversary of the Commencement Date and with
respect to 1/48th of the shares initially subject thereto on each monthly anniversary of the Commencement Date thereafter,
subject to Executive’s continued service to the Company through the applicable vesting date, provided, that upon occurrence
of a Change of Control, subject to Executive’s continued service to the Company through the date of such Change of Control,
the Option shall vest and become exercisable with respect to one hundred percent (100%) of the unvested shares subject thereto.
The Option shall be exercisable in full on the Grant Date, subject to Executive entering into a restricted stock purchase agreement
with respect to any unvested shares. Executive shall be permitted to exercise any or all of the Option, whether or not vested,
subject to the Company’s right of repurchase. The Option otherwise shall be subject to and governed in all respects by the
terms of the Plan and the option agreement to be entered into between the Company and Executive. 

     3.4 Standard Company Benefits;
Vacation. With the exception of health
care, vision and dental benefits, Executive shall be entitled to all rights and
benefits for which Executive is eligible under the terms and conditions of the
Company’s benefit and compensation plans, practices, policies and programs, as
in effect from time to time, that are provided by the Company to its senior
executives generally. Executive will be eligible for twenty (20) days of
vacation per year.

ARTICLE IV
SEVERANCE BENEFITS AND RELEASE 

     4.1 Severance
Benefits. If Executive’s employment
terminates due to a Covered Termination after the date of execution of this
Agreement, Executive shall receive: 

          (i) Payment of
Accrued Obligations Upon Termination of Employment. Upon a termination of Executive’s employment for any reason at any time
following the Commencement Date, the Company shall pay to Executive in a single
lump-sum cash payment as soon as administratively practicable following the date
of termination, the aggregate amount of Executive’s (A) earned but unpaid Base
Salary, and (B) accrued but unpaid vacation pay. In addition, Executive shall be
promptly paid for incurred but unreimbursed business expenses upon his
submission of such expenses in accordance with the Company’s expense
reimbursement policies. The amounts set forth in this Section 4.1(i) are
collectively referred to as the “Accrued
Obligations”.

          (ii) Severance
Upon a Covered Termination. If Executive’s
employment terminates due to a Covered Termination at any time after the
Commencement Date, then, in addition to the Accrued Obligations:

               (a) Executive
shall be paid target Annual Bonus for the fiscal year in which the termination
occurs, prorated for the length of service provided during the calendar year
through the termination date, payable in a single lump-sum payment within thirty
(30) days following the date of termination;

               (b) Executive
shall be paid an aggregate amount equal to twelve (12) months of Executive’s
Base Salary in effect on the date of termination, payable to Executive in a
single lump-sum amount on the sixtieth (60th) day following the date
of termination; 

               (c)
Executive and Executive’s covered dependents will be eligible to continue their health care benefit coverage as permitted
by COBRA (Internal Revenue Code Section 4980B) at the Company’s expense for the lesser of (i) twelve (12) months following
the Covered Termination, or (ii) until the Executive and/or Executive’s covered dependents are no longer eligible for COBRA
(for clarification and as an example, in the event Executive is covered by another health plan, etc.). Thereafter, Executive and
Executive’s covered dependents shall be entitled to maintain coverage for Executive and Executive’s eligible dependents
at Executive’s own expense for the balance of the period that Executive is entitled to coverage under COBRA; and

               (d) the
Option, along with any subsequent options or other exercisable equity interest in the Company held by Executive shall remain outstanding
and exercisable through the earlier of (i) the second (2nd) anniversary of the date of termination or (ii) the original
expiration date of the option or other equity interest. 

Notwithstanding the foregoing, the
amounts payable under this Article IV, other than the Annual Bonus and the
extended exercisability set forth in Section 4.1(d), shall be reduced by the
amount of severance or other cash compensation, if any, payable under the
Company’s Change of Control Severance Plan attached hereto as Exhibit C. For the
avoidance of doubt, all amounts payable under this Agreement shall be subject to
applicable federal, state, local or foreign tax withholding
requirements.

4

     4.2 Parachute
Payments. If any payment or benefit
Executive would receive in connection with a Change in Control from the Company
or otherwise (“Payment”) would (i) constitute a “parachute payment” within the
meaning of Section 280G of the Code, and (ii) but for this sentence, be subject
to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such
Payment shall be reduced to the Reduced Amount. The “Reduced Amount” shall be
either (x) the largest portion of the Payment that would result in no portion of
the Payment being subject to the Excise Tax or (y) the largest portion, up to
and including the total, of the Payment, whichever amount, after taking into
account all applicable federal, state and local employment taxes, income taxes,
and the Excise Tax (all computed at the highest applicable marginal rate),
results in Executive’s receipt, on an after-tax basis, of the greater amount of
the Payment notwithstanding that all or some portion of the Payment may be
subject to the Excise Tax. If a reduction in payments or benefits constituting
“parachute payments” is necessary so that the Payment equals the Reduced Amount,
reduction shall occur in the following order unless Executive elects in writing
a different order (provided, however, that such election shall be subject to
Company approval): reduction of cash payments; cancellation of accelerated
vesting of stock awards; reduction of employee benefits. In the event that
acceleration of vesting of stock award compensation is to be reduced, such
acceleration of vesting shall be cancelled in the reverse order of the date of
grant of Executive’s stock awards unless Executive elects in writing a different
order for cancellation. 

The Company for general audit purposes shall engage a
nationally recognized public accounting firm (the “Accounting Firm”) to perform the foregoing calculations. The
Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. The
Accounting Firm engaged to make the determinations hereunder shall provide its calculations, together with detailed
supporting documentation, to the Company and Executive within fifteen (15) calendar days after the date on which
Executive’s right to a Payment is triggered (if requested at that time by the Company or Executive) or such other time
as requested by the Company or Executive. If the Accounting Firm determines that no Excise Tax is payable with respect to a
Payment, either before or after the application of the Reduced Amount, it shall furnish the Company and Executive with an
opinion reasonably acceptable to Executive that no Excise Tax will be imposed with respect to such Payment. Any good faith
determinations of the accounting firm made hereunder shall be final, binding and conclusive upon the Company and Executive. 

     4.3 Release. Notwithstanding the foregoing, Executive’s right to receive
the amounts provided for in Sections 4.1(ii) and 4.2, and the Change of Control
acceleration referenced in Section 3.3 above shall be subject to and conditioned
upon Executive’s execution and non-revocation of a release of claims in
substantially the form attached hereto as Exhibit A (the “Release”) (as such form may
be modified to take into account changes in the law) within fifty (50) days
following the termination date. Such Release shall specifically relate to all of
Executive’s rights and claims in existence at the time of such execution and
shall confirm Executive’s obligations under the Proprietary Information
Agreement (as defined below). It is understood that Executive has a certain
period to consider whether to execute such Release, as set forth in the Release,
and Executive may revoke such Release within seven (7) business days after
execution. In the event Executive does not execute such Release within the
applicable period, or if Executive revokes such Release within the subsequent
seven (7) business day period, none of the aforesaid benefits set forth in
Sections 4.1(ii), 4.2 and the Change of Control acceleration referenced in
Section 3.3 shall be payable to Executive under this Agreement and this
Agreement shall be null and void.

5

     4.4 Section 409A.
Notwithstanding any provision to the
contrary in this Agreement, if Executive is deemed by the Company at the time of
the Separation from Service to be a “specified employee” for purposes of Section
409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of any portion
of the benefits to which Executive is entitled under this Agreement is required
in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of
the Code, such portion of Executive’s benefits shall not be provided to
Executive prior to the earlier of (a) the expiration of the six-month period
measured from the date of Executive’s Separation from Service or (b) the date of
Executive’s 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 Section 4.4 shall be paid in a lump sum to Executive (or Executive’s
estate or beneficiaries), and any remaining payments due under the Agreement
shall be paid as otherwise provided herein. For purposes of Section 409A of the
Code, Executive’s right to receive the payments of compensation pursuant to the
Agreement shall be treated as a right to receive a series of separate payments
and accordingly, each payment shall at all times be considered a separate and
distinct payment. 

     4.5 Mitigation.
Executive shall not be required to
mitigate damages or the amount of any payment provided under this Agreement by
seeking other employment or otherwise, nor shall the amount of any payment
provided for under this Agreement be reduced by any compensation earned by
Executive as a result of employment by another employer or by any retirement
benefits received by Executive after the date of the Covered Termination, or
otherwise. 

ARTICLE V
PROPRIETARY INFORMATION OBLIGATIONS 

     5.1 Agreement. Executive agrees to
abide by the Proprietary Information and Inventions Agreement attached hereto as
Exhibit B
(the “Proprietary Information
Agreement”). 

     5.2 Remedies.
Executive’s duties under the Proprietary
Information and Inventions Agreement shall survive termination of Executive’s
employment with the Company and the termination of this Agreement. Executive
acknowledges that a remedy at law for any breach or threatened breach by
Executive of the provisions of the Proprietary Information and Inventions
Agreement would be inadequate, and Executive therefore agrees that the Company
shall be entitled to injunctive relief in case of any such breach or threatened
breach.

ARTICLE VI
OUTSIDE ACTIVITIES

     6.1 No Other Employment.
Except with the prior written consent of
the Board, Executive shall not during the term of Executive’s employment with
the Company, undertake or engage in any other employment, occupation or business
enterprise. Notwithstanding the foregoing, during the term of Executive’s
employment with the Company, Executive may (a) undertake or engage in any other
employment, occupation or business enterprise in which Executive is a passive
investor, and/or (b) engage in civic and not-for-profit activities, in each
case, so long as such activities do not materially interfere with the
performance of Executive’s duties hereunder. 

     6.2 No Conflicting Business
Interests. During the term of
Executive’s employment by the Company, except on behalf of the Company,
Executive shall not directly or indirectly, whether as an officer, director,
stockholder, partner, proprietor, associate, representative, consultant, or in
any capacity whatsoever engage in, become financially interested in, be employed
by or have any business connection with any other person, corporation, firm,
partnership or other entity whatsoever which were known by Executive to compete
directly with the Company, throughout the world, in any line of business engaged
in (or planned to be engaged in) by the Company; provided, however, that anything above
to the contrary notwithstanding, Executive may own, as a passive investor,
securities of any competitor corporation, so long as Executive’s direct holdings
in any one such corporation shall not in the aggregate constitute more than 1%
of the voting stock of such corporation.

ARTICLE VII
NONINTERFERENCE

     While employed by the Company, and
for one (1) year immediately following the date on which Executive terminates
employment or otherwise ceases providing services to the Company, Executive
agrees not to interfere with the business of the Company by soliciting or
attempting to solicit any employee of the Company to terminate such employee’s
employment in order to become an employee, consultant or independent contractor
to or for any competitor of the Company. Executive’s duties under this Article
VII shall survive termination of Executive’s employment with the Company and the
termination of this Agreement. 

ARTICLE VIII
GENERAL PROVISIONS

     8.1 Notices. Any notices provided hereunder must be in writing and shall be
deemed effective upon the earlier of personal delivery (including personal
delivery by telex) or the third day after mailing by first class mail, to the
Company at its primary office location and to Executive at Executive’s address
as listed on the Company payroll. 

7

     8.2 Section 409A.
To the extend applicable, this Agreement
shall be interpreted in accordance with Section 409A of the Code and Department
of Treasury regulations and other interpretative guidance issued thereunder,
including without limitation any such regulations or other such guidance that
may be issued after the Commencement Date (“Section 409A”). Notwithstanding any provision of this
Agreement to the contrary, in the event that following the Commencement Date,
the Company determines in good faith that any compensation or benefits payable
under this Agreement may not be either exempt from or compliant with Section
409A, the Company may adopt such amendments to this Agreement or adopt other
policies or procedures (including amendments, policies and procedures with
retroactive effect), or take any other commercially reasonable actions necessary
or appropriate to preserve the intended tax treatment of the compensation and
benefits payable hereunder, including without limitation actions intended to (i)
exempt the compensation and benefits payable under this Agreement from Section
409A, and/or (ii) comply with the requirements of Section 409A, provided, that
this Section 8.2 does not, and shall not be construed so as to, create any
obligation on the part of the Company to adopt any such amendments, policies or
procedures or to take any other such actions or to create any liability on the
part of the Company for any failure to do so. 

     8.3 Severability. Whenever possible,
each provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this Agreement
is held to be invalid, illegal or unenforceable in any respect under any
applicable law or rule in any jurisdiction, such invalidity, illegality or
unenforceability will not affect any other provision or any other jurisdiction,
but this Agreement will be reformed, construed and enforced in such jurisdiction
as if such invalid, illegal or unenforceable provisions had never been contained
herein. 

     8.4 Waiver. If either party should waive any breach of any provisions of
this Agreement, they shall not thereby be deemed to have waived any preceding or
succeeding breach of the same or any other provision of this Agreement.

     8.5 Complete
Agreement. This Agreement and its
Exhibit A and Exhibit B constitute the entire agreement between Executive and
the Company and are the complete, final, and exclusive embodiment of their
agreement with regard to this subject matter (except for the Plan, any successor
thereto or the Company’s Change of Control Severance Plan). This Agreement
supersedes any prior agreement between Executive and the Company or any
predecessor employer in its entirety. Executive and the Company acknowledge and
agree that this Agreement is entered into without reliance on any promise or
representation other than those expressly contained herein or therein and cannot
be modified or amended except in a writing signed by a duly-authorized officer
of the Company. 

     8.6 Counterparts. This Agreement may
be executed in separate counterparts, any one of which need not contain
signatures of more than one party, but all of which taken together will
constitute one and the same Agreement. 

     8.7 Headings.
The headings of the sections hereof are
inserted for convenience only and shall not be deemed to constitute a part
hereof nor to affect the meaning thereof. 

     8.8 Successors and
Assigns. This Agreement is intended to
bind and inure to the benefit of and be enforceable by Executive and the
Company, and their respective successors, assigns, heirs, executors and
administrators, except that Executive may not assign any of Executive’s duties
hereunder and Executive may not assign any of Executive’s rights hereunder,
without the written consent of the Company, which shall not be withheld
unreasonably. 

8

     8.9 Arbitration. In the event of any
contractual, statutory or tort dispute or claim relating to or arising out of
Executive’s employment relationship with the Company (including but not limited
to any claims of wrongful termination or age, sex, race, or other
discrimination, but not including workers’ compensation claims), Executive and
the Company agree that all such disputes will be finally resolved by binding
arbitration conducted by a single neutral arbitrator associated with the
American Arbitration Association in Menlo Park, California. Executive and the
Company hereby waive their respective rights to have any such disputes or claims
tried to a judge or jury. However, the Company agrees that this arbitration
provision will not apply to any claim, by either Executive or the Company, for
injunctive relief. The administrative costs of any arbitration proceeding
between Executive and the Company and the fees and costs of the arbitrator shall
be borne by the Company. 

     8.10 Attorneys’
Fees. If either party hereto brings any
action to enforce rights hereunder, each party in any such action shall be
responsible for its own attorneys’ fees and costs incurred in connection with
such action. 

     8.11 Acknowledgement. Executive
acknowledges that Executive (a) has had the opportunity to discuss this matter
with and obtain advice from independent counsel of Executive’s own choice and
has been advised to do so by the Company, (b) has carefully read and fully
understands all the provisions of this Agreement, and (c) is knowingly and
voluntarily entering into this Agreement. Executive represents that Executive
(i) is familiar with the restrictive covenants set forth in the Proprietary
Information Agreement and (ii) is fully aware of his/her obligations thereunder.

     8.12 Choice of
Law. All questions concerning the
construction, validity and interpretation of this Agreement will be governed by
the law of the State of California.

Commencement Date. Commencement Date shall be
defined to mean the earliest to occur of the following:

of the Premises for the conduct of its business; or 

              
(ii) the Estimated Commencement Date specified in section C.4. of the
Information Sheet. 

          If for any
reason Landlord does not or cannot deliver possession of all or any portion of
the Premises to Tenant by the Estimated Commencement Date, Landlord shall not be
subject to any liability therefore, nor shall such failure affect the validity
of this Lease or the obligations of Tenant hereunder, provided that such delay
does not exceed thirty (30) days from the Estimated Commencement Date, but in
such case, Tenant shall not be obligated to pay any Monthly Rent hereunder,
until the date that Landlord delivers possession of the entire Premises to

adjustment in the Commencement Date shall alter the validity of this Lease or

delay or adjustment cause the expiration date of this Lease to be later than
July 12, 2014. If for any reason Landlord does not deliver possession of all or
any portion of the Premises to Tenant for a period exceeding thirty (30) days
from the Estimated Commencement Date, Tenant shall be entitled to terminate this

obligations under this Lease shall cease with respect to, such portion of the
Premises. Except as set forth in the Work Letter with respect to the hanging
conference room wall, if Landlord fails to deliver at least ninety percent (90%)

of monitoring the planning and construction of the Tenant Improvements
consisting of the Initial Installation by Landlord, in accordance with the
provisions of EXHIBIT C, installing its furniture, fixtures and telephone, internet
and data communications cabling and wiring, excluding the conduct of its
business. Such early entry shall be at Tenant’s sole risk and subject to all the
terms and provisions hereof, except for the payment of Monthly Rent which shall
commence on the date set forth in Paragraph 4.B. Whereupon certain Suites are
currently occupied by other tenants, immediately upon vacation of such Suites by
the existing tenants, Tenant will be granted access to such Suites. With respect
to Suites not currently occupied by other tenants, Tenant will be granted access
immediately upon execution of this Lease and provision of a Certificate of
Insurance as set forth herein. Upon reasonable prior written notice to Landlord,
and subject to Landlord’s completion of any Tenant Improvements requested by
Tenant pursuant to EXHIBIT C with respect thereto, Tenant will have the right to occupy

request occupancy of Suite 2118 prior to the Commencement Date, the parties will
agree in writing upon a date certain for the commencement of such occupancy, and
the rights and obligations of the Parties pursuant to this Lease with respect to
Suite 2118, including, without limitation, Tenant’s obligation to pay Rent with
respect to Suite 2118, shall be effective upon the date of such occupancy. Early
occupancy by Tenant of any portion of the Premises, including Suite 2118, shall
not cause the expiration date of this Lease to be later or earlier than July 12,
2014.

         
E.
Option To Extend. 

              
(i) Conditions to Exercise of

Default under this Lease at the time of exercise of the option to extend or at
the commencement of the extension term, Tenant shall have the right to extend
the Term of this Lease for an additional period of two (2) years
(“Extension Term”) commencing on July 13, 2014. 

              
(ii) Notice of Exercise. If Tenant elects to extend this Lease for the Extension
Term, Tenant shall deliver written notice (“Exercise Notice”) of its exercise to
Landlord not earlier than two hundred seventy (270) days prior to the Expiration Date of the initial Term of
this Lease and not less than one hundred eighty (180) days prior to the
Expiration Date of the initial Term of this Lease. Tenant’s failure to deliver
the Exercise Notice in a timely manner shall be deemed a waiver of Tenant’s
rights to extend the Term of this Lease. 

-6-

              
(iii) Terms of the
Extension Term. The delivery of an Exercise
Notice shall constitute an irrevocable election by Tenant to extend the Term of
the Lease upon the terms, covenants and conditions set forth herein. The terms,
covenants and conditions applicable to the Extension Term shall be the same
terms, covenants and conditions of this Lease except that (i) Tenant shall not
be entitled to any further option to extend after the Extension Term; (ii) the

(iv) Extension Option Personal to
Original Tenant. The option to extend granted

shall only apply to that portion of the Premises subleased to a third party
other than a Permitted Transferee, and shall survive with respect to any other
portion of the Premises not so subleased by Tenant. 

    
5.
Rent.

         
A.
Monthly Rent.

          Tenant
shall pay the First Month’s Base Rent by the Commencement Date. Notwithstanding
the foregoing, the parties acknowledge and agree that under that certain Office
Lease Agreement dated May 1, 2007 by and between the parties (the “2007 Lease”),
Tenant has previously paid in full all rent due with respect to Suite 2070 up to
and including July 31, 2012. Accordingly, no Base Rent shall be due under this
Lease by Tenant with respect to Suite 2070 from the Commencement Date up to and
including July 31, 2012. Thereafter, on or before the first day of each calendar
month, without prior notice or demand, deduction or offset, Tenant shall pay
Monthly Rent to Landlord, in lawful money of the United States at the Office of
the Landlord specified in section C.11. of the Information Sheet, or to such
other place or person as Landlord may designate in the manner set forth in
Paragraph 31. Monthly Rent shall consist of the sum of the following:

              
(i) Base Rent. Base Rent in the amount specified in section C.6. of the
Information Sheet.; and 

              
(ii) Monthly Operating Expense
Reimbursement. The Monthly Operating Expense Reimbursement (“Monthly Operating Expense Reimbursement”) shall equal to one twelfth (1/12) of Tenant’s Building
Percentage of the amount by which Landlord’s estimate of the Operating Expenses
for the relevant calendar year of the Term exceeds the Base Year Operating
Expenses, as such terms are defined in Paragraph 15. 

-7-

              
(iii) Tenant
Improvement Allowance Reimbursement.
The Tenant Improvement Allowance
Reimbursement (“Tenant Improvement Allowance
Reimbursement”) shall equal, for every *
dollar ($*) per square foot of Tenant Improvement Allowance utilized by Tenant
in accordance with EXHIBIT C, the amount of * ($*) divided by the number of months remaining
in the Term at the time such Tenant Improvement Allowance is utilized,
multiplied by the rentable area specified in section C.2.a. of the Information
Sheet. Reimbursement of any Tenant Improvement Allowance hereunder shall
commence with the first payment of Monthly Rent due immediately after
utilization of the Tenant Improvement Allowance by Tenant. 

         
B.
Prorations.

          If the
Commencement Date is not the first (1st) day of a month, or if the termination
date is not the last day of a month, a prorated monthly installment based on a
thirty (30) day month shall be paid for the fractional month during which this
Lease commences or terminates. 

         
C.
Periodic Adjustments.

          There shall
be no periodic adjustments to the monthly Base Rent to be paid by Tenant during
the Term of this Lease. 

         
D.
Determination of Monthly Base Rent During
Extension Term.

              
(i) Extension Term Initial Monthly
Base Rent. The monthly Base Rent payable
during the first year of the Extension Term (the “Extension Term Initial Monthly
Base Rent”) shall be the then-prevailing fair market rental value for the
comparable space located in the Menlo Park area, but in no event be less than
the monthly Base Rent as provided in section C.6 of the Information Sheet, or
greater than one hundred and twenty percent (120%) of the monthly Base Rent as
provided in section C.6 of the Information Sheet. The Extension Term Initial
Monthly Base Rent shall increase by three percent (3%) on an annual
basis.

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

-8-

              
(ii) Fair Market
Rental Value. Fair Market Rental Value as
used herein shall mean: 100% of the monthly base rent and other amounts new
tenants are then generally agreeing to pay under leases then being executed or
renewed for comparable, improved office space in the Highway 101/Menlo Park
submarket for office space. In determining the fair market rental value of the
Premises during the Extension Term, consideration shall be given to all relevant
factors, including, without limitation, such factors as credit-worthiness of the
tenant, the duration of the term, any rental or other concessions granted,
whether a broker’s commission or finder’s fee will be paid, responsibility for
Operating Expenses, the uses of the Premises permitted under this Lease and the
quality, condition, size, design and location of the Premises. Notwithstanding anything to the contrary contained in this
Lease, the Base Year for the Extension Term for purposes of determining Tenant’s
share of Monthly Operating Expenses during the Extension Term shall be the
calendar year in which the Extension Term commences. 

              
(iii) Landlord and Tenant to Seek to
Agree. Landlord and Tenant shall have
thirty (30) days after Landlord receives the Exercise Notice in which to seek to
agree on the Extension Term Initial Monthly Base Rent. If Landlord and Tenant
agree on the Extension Term Initial Monthly Base Rent during such thirty (30)
day period (or at any time thereafter), they shall promptly execute an amendment
to this Lease confirming the Extension Term Initial Monthly Base Rent as so
agreed as the monthly Base Rent for the first year of the Extension
Term.

              
(iv) Selection of Brokers to
determine the Extension Term
Initial Monthly Base
Rent. If Landlord and Tenant are unable
to agree on the Extension Term Initial Monthly Base Rent within the thirty (30)
day period, then within ten (10) days after the expiration of the thirty (30)
day period, Landlord and Tenant each, at its cost and by giving notice to the
other party, shall appoint a licensed commercial real estate broker with at
least five (5) years’ full-time commercial brokerage experience in the
geographical area of the Project (a “Broker”) to evaluate and set the
Extension Term Initial Monthly Base Rent. If either Landlord or Tenant does not
appoint a Broker within ten (10) days after the other party has given notice of
the name of its Broker, the single Broker appointed shall be the sole Broker and
shall set the Extension Term Initial Monthly Base Rent. If two (2) Brokers are
appointed by Landlord and Tenant as stated in this Paragraph, they shall meet
promptly and attempt to set the Extension Term Initial Monthly Base Rent. If the
two (2) Brokers are unable to agree within thirty (30) days after the second
Broker has been appointed, they shall attempt to select a third Broker meeting
the qualifications stated in this Paragraph (with the additional qualification
that such third Broker shall have had no prior, current, or presently committed
future business or personal relationship with either Landlord or Tenant) within
ten (10) days after the last day the two (2) Brokers are given to set the
Extension Term Initial Monthly Base Rent; provided, however, if the two Broker’s
proposed Extension Term Initial Monthly Base Rent figures are ten percent (10%) or less
apart, the two figures shall be added together and such total be divided by two
to determine the Extension Term Initial Monthly Base Rent. If they are unable to
agree on the third Broker, either Landlord or Tenant, by giving ten (10) days’
notice to the other party, can apply to the then Presiding Judge of the Superior
Court of San Mateo County for the selection of a third Broker who meets the
qualifications stated in this Paragraph. Landlord and Tenant each shall bear
one-half (1/2) of the cost of appointing the third Broker and of paying the
third Broker’s fee. Any time period set forth herein may be extended if mutually
agreed in writing by the parties, to allow for further negotiation. 

-9-

              
(v) Value
Determined by Three (3) Brokers. Within
thirty (30) days after the selection of the third Broker, a majority of the
Brokers shall set the Extension Term Initial Monthly Base Rent. If a majority of
the Brokers is unable to set the Extension Term Initial Monthly Base Rent within
the stipulated period of time, the three (3) evaluations shall be added together
and their total divided by three (3); the resulting quotient shall be the
Extension Term Initial Monthly Base Rent for the Premises. If the low evaluation
is more than ten percent (10%) lower than the middle evaluation, the low
evaluation shall be disregarded; if the high evaluation is more than
ten percent (10%) higher than the middle
evaluation, the high evaluation shall be disregarded. If only one (1) evaluation
is disregarded, the remaining two (2) evaluations shall be added together and
their total divided by two (2); the resulting quotient shall be the Extension
Term Initial Monthly Base Rent for the Premises. If both the low evaluation and
the high evaluation are disregarded as stated in this Paragraph, the middle
evaluation shall be the Extension Term Initial Monthly Base Rent for the
Premises.

              
(vi) Notice to Landlord and
Tenant. After the Extension Term Initial
Monthly Rent for the first year of the Extension Term has been set, the Brokers
shall notify Landlord and Tenant immediately and Landlord and Tenant shall
promptly execute an amendment to this Lease confirming the Extension Term
Initial Monthly Rent as so determined as the Monthly Rent for the first year of
the Extension.

Late Payment Charges. TENANT ACKNOWLEDGES
THAT LATE PAYMENT BY TENANT TO LANDLORD OF RENT
AND OTHER CHARGES PROVIDED FOR UNDER THIS LEASE WILL CAUSE LANDLORD TO INCUR
COSTS NOT CONTEMPLATED BY THIS LEASE, THE EXACT AMOUNT OF SUCH COSTS BEING
EXTREMELY DIFFICULT OR IMPRACTICABLE TO FIX. THEREFORE, IF ANY INSTALLMENT OF
RENT OR ANY OTHER CHARGE DUE FROM TENANT IS NOT RECEIVED BY LANDLORD WITHIN TEN
(10) DAYS FOLLOWING THE DATE OF LANDLORD’S DELIVERY OF WRITTEN NOTICE TO TENANT
STATING THAT SUCH AMOUNT WAS NOT RECEIVED ON OR BEFORE THE DATE DUE, TENANT
SHALL PAY TO LANDLORD 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
LANDLORD WILL INCUR BY REASON OF THE LATE PAYMENT BY TENANT. SUCH LATE CHARGE SHALL BE IN
ADDITION TO, AND NOT IN LIEU OF, ANY INTEREST THAT MAY ACCRUE ON ANY SUCH
OVERDUE AMOUNT PURSUANT TO THE PROVISIONS OF PARAGRAPH 44.

Lease.

    
8.
Holding Over. If Tenant remains in possession
of all or any part of the Premises after the
expiration of the Term, without the consent of Landlord, such tenancy shall be
from month-to-month only and not a renewal hereof or any extension for any
further term, and in such case, Monthly Rent shall be increased to an amount
equal to one hundred
fifty percent (150%) of the Monthly Rent paid during the last month of the Term
and all other sums due hereunder shall be payable in the amount and at the time
applicable at the time of expiration and at the time specified in this Lease and
such month-to-month tenancy shall be subject to every other term, covenant and
agreement of this Lease, excluding any option to extend the Term. In addition,
Tenant shall defend, indemnify
and hold Landlord, and Landlord’s Agents free and harmless from and against any
claim, loss, liability, expense or damage, including reasonable attorneys’ fees
and costs, arising out of Tenant’s failure to surrender the Premises at the
expiration of the Term, including, without limitation, any such damages
resulting from Landlord’s inability to honor its commitments to any other tenant
for the Premises. 

    
9.
Tenant Improvements. Landlord shall provide, for
Tenant’s benefit, the Tenant Improvement
Allowance set forth in Paragraph 2(f) of the Work Letter attached hereto as
EXHIBIT C.
Tenant shall have the right, but not the obligation, to utilize some or all of
such Tenant Improvement Allowance for the purpose of constructing any Tenant
Improvements permitted under this Lease (including, without limitation, the
Initial Installation (as defined by the Work Letter) or any future Alterations).
Landlord and Tenant agree to the terms and procedures for the planning,
construction and funding of the construction of the Tenant Improvements
comprising the Initial Installation as set forth in EXHIBIT C. 

-11-

    
10. Condition of
Premises. Landlord represents and warrants that the Building complied with all
local and state codes and ordinances and all American with Disabilities Act
requirements at the time of construction in 1989 and has been maintained in
compliance with the foregoing. Notwithstanding anything to the contrary set
forth in this Lease, should applicable law or any government agency require
modification of the Outside Area or common space within the Building, or of the
Premises, to permit use of thereof for general office purposes, such
modifications will be at Landlord’s sole cost. By taking possession of the
Premises, Tenant shall be deemed to have accepted the Premises in “As Is”
condition (except for the Initial Installations as set forth in Exhibit C), in
good, clean and completed condition and repair, subject to all applicable laws,
codes and ordinances. Tenant acknowledges that, except as expressly set forth in
this Lease, neither Landlord nor Landlord’s Agents have made any representations
or warranties as to the suitability or fitness of the Premises or any other part
of the Project (including, without limitation, the intra-building network
cabling) for the conduct of Tenant’s business or for any other purpose, nor has
Landlord or Landlord’s Agents agreed to undertake any Alterations or construct
any Tenant Improvements to the Premise except as expressly provided in
EXHIBIT C
of this Lease.

     11.Use of the Premises.

         
A.
Tenant’s Use. Tenant shall use the Premises
solely for general office purposes and shall not use the Premises for any other
purpose without obtaining the prior written consent of Landlord, which Landlord
may withhold in its sole and absolute discretion. Tenant agrees that the
Property is subject and this Lease is subordinate to the CC&R’s, a copy of
which has been provided to Tenant. Tenant acknowledges that it has read the
CC&R’s and knows the contents thereof. Throughout the Term, Tenant shall
faithfully and timely perform and comply with the CC&R’s and any
modification or amendments thereof, provided that Tenant is notified thereof
by Landlord.
Tenant shall comply with all duly adopted rules, regulations and restrictions as
may be adopted from time to time by any committee established pursuant to the
CC&Rs (“Association”), provided that Tenant is notified thereof by Landlord.
Any periodic or special dues or Outside Area assessments of the Association
shall be included within the definition of Operating Expenses pursuant to
Paragraph 15.B. and Tenant shall pay Tenant’s Building Percentage of such
amounts over the Base Year amounts as further set forth in Paragraph 15. Tenant
shall defend, indemnify and hold Landlord, and Landlord’s Agents free and
harmless from and against any claim, loss, liability, expense or damage,
including reasonable attorneys’ fees and costs, arising out of the actual or
asserted failure of Tenant to perform or comply with the CC&R’s. Tenant
shall not permit or make any use of the Premises which will increase the
existing rate of insurance upon the Project, or cause the cancellation of any
insurance policy covering the Project, or any part thereof. If the existing rate
of insurance shall be increased or any insurance policy covering the Project is
canceled as a result of Tenant’s or Tenant’s Agent’s acts or omissions, then
Landlord, in addition to such remedies as Landlord may have under this Lease or
pursuant to law or equity, shall be entitled to reimbursement from Tenant within
ten (10) days after receipt of written demand therefor for the entire amount of
said increase or any additional amount which must be paid for a new insurance
policy. 

-12- 

         
B. Compliance.
Tenant shall not use the Project or  permit Tenant’s Agents to do
anything in or about the Project in conflict with  any law, statute, zoning restriction, ordinance or governmental law, rule,
regulation or requirement of duly constituted public  authorities now in force or which may hereafter be in force, or the
requirements  of the Board of Fire Underwriters or other similar body now or hereafter  constituted relating to or affecting
the condition, use or occupancy of the  Project. If any law, statute, zoning restriction, ordinance or governmental law,
rule, regulation or requirement of duly constituted public  authorities requires any capital improvement to the Premises or
the Building  solely as the result of Tenant’s particular use of the Premises, then Tenant  shall be responsible for the
same (or at the election of Landlord, for  reimbursing Landlord for the cost of performing the same); provided, however,
that if such capital improvement is so required for any reason other than  Tenant’s particular use of the Premises, then
Landlord shall be responsible for  the same, at Landlord’s sole cost and expense, subject to Landlord’s right to
include such amounts as Operating Expenses on an amortized basis as provided in  Paragraph 15.B. Tenant shall not abandon the
Premises; provided, however, that  if Tenant vacates the Premises while performing all of Tenant’s other  obligations
under this Lease, such vacation shall not be deemed an abandonment  and a Default hereunder. Tenant shall not commit any
public or private nuisance  or any other act or practice which might or would disturb the quiet enjoyment of  any other
tenant of Landlord or any occupant of nearby properties. Tenant shall  place no loads upon the floors, walls or ceilings in
excess of the maximum  designed load determined by Landlord or which endanger the structure; nor place  any harmful liquids
in the drainage systems; nor dump or store waste materials  or refuse or allow such to remain outside the Building proper,
except in the  enclosed trash areas provided. Tenant shall not store or permit to be stored or  otherwise placed any material
of any nature whatsoever outside the Building. If  as a result of any Tenant-specific use or change in Tenant-specific use of
the  Premises by Tenant, any alterations are required to the Premises, the Building  or the Project by applicable laws,
including, without limitation, the Americans  with Disabilities Act or any state or local building, fire or safety codes,
ordinances or regulations, Tenant shall be responsible for the same (or at the  election of Landlord, for reimbursing
Landlord for the cost of performing the  same). Except as expressly set forth in this Lease, any alterations required to  the
Premises, the Building or the Project by applicable laws, including, without  limitation, The Americans with Disabilities Act
or any state or local building,  fire or safety codes, ordinances or regulations, shall be at Landlord’s
cost.

-13- 

         
C. Toxic Material. Tenant,
at its sole cost, shall  comply with and cause Tenant’s Agents to comply with all laws relating to the  storage, use and
disposal of hazardous, toxic or radioactive matter, including  those materials identified in Sections 66680 through 66685 of
Title 22 of the  California Administrative Code, Division 4, Chapter 30 (“Title 22”) as they may  be amended from
time to time (collectively, “Toxic Materials”). If Tenant or  Tenant’s Agents desire to store, use or dispose
of any Toxic Materials in, on or  about the Premises (other than the storage and use of reasonable quantities of  customary
office supplies), Tenant shall first request and obtain Landlord's  approval to such proposed storage, use or disposal in
writing, which request  must be made at least ten (10) days prior to the storage, use or disposal  thereof in, on or about
the Premises. Whether or not Landlord is aware or  approves of the storage, use or disposal of any Toxic Material by Tenant
or Tenant’s Agents, Tenant shall be solely responsible for and shall defend,  indemnify and hold Landlord and Landlord's
Agents harmless from and against all  claims, costs and liabilities, including reasonable attorneys' fees and costs,  arising
out of or in connection with the storage, use, generation,  transportation, disposal or release of Toxic Materials by Tenant
or Tenant’s  Agents, including without limitation, any such claims, costs, damages and  liabilities (including
reasonable attorneys' fees and costs) arising out of or  in connection with any investigation, testing, remediation, removal,
clean-up  and/or restoration services, work, materials and equipment necessary to return  the Premises and any other property
of whatever nature to their condition  existing prior to the storage, use, generation, transportation, disposal or  release
of Toxic Materials by Tenant or Tenant’s Agents in, on or about the  Premises or the Project, and to otherwise
satisfactorily investigate and  remediate the contamination arising therefrom to the reasonable satisfaction of  Landlord and
all governmental authorities. The foregoing indemnification  obligation shall likewise apply to Landlord with respect to
Tenant and Tenant’s  Agents, as to any Toxic Materials maintained in the Building by Landlord. If at  any time during or
after the term of this Lease, as it may be extended, Tenant  becomes aware of any injury, investigation, administrative
proceeding, or  judicial proceeding regarding the storage, use or disposition of any Toxic  Materials by Tenant or Tenant's
Agents on or about the Premises or the Project,  Tenant shall within five (5) days after first learning of such injury,
investigation or proceeding give Landlord written notice advising Landlord of  same. Tenant acknowledges receipt of a copy of
that certain June 1998 Focused  Environmental Site Assessment, 149 Commonwealth Drive, Menlo Park, California,  dated as of
August 16, 1998, prepared by The Gauntlett Group, LLC, together with  all attachments thereto (“Site Assessment”),
that Landlord previously made  available to Tenant, and which Tenant agrees to maintain in confidence. In  addition, Landlord
utilizes Toxic Materials in the operation of its business.  Landlord represents and warrants to Tenant that Landlord uses all
such Toxic  Materials in compliance with all applicable laws, rules, regulations and  ordinances.

         
D.
Transportation Systems
Management. Tenant shall comply with the requirements of the City or County mandated
parking or transportation systems management ordinances. 

         
E.
Rules and Regulations. The Rules and
Regulations for the Project in effect as of the Effective Date are attached
hereto as EXHIBIT E. Landlord reserves the right to adopt or amend the Rules and Regulations
from time to time in its reasonable discretion. Tenant agrees that Tenant, its
employees and agents and, to the extent Tenant can require the same, its
invitees, shall observe and perform the Rules and Regulations as they may be
amended or adopted. A breach of the Rules and Regulations by Tenant or such
persons shall constitute a Default under this Lease as if the Rules or
Regulations were contained in this Lease as covenants of the Tenant. Tenant
acknowledges that Landlord has no obligation to enforce, and shall have no
liability for non-enforcement of, the Rules and Regulations. Notwithstanding the
foregoing, in the event of any inconsistency between the Rules and Regulations
and the provisions of this Lease, the provisions of this
Lease shall control, and Landlord shall not enforce the Rules and Regulations in
a discriminatory manner. 

-14- 

     12. Quiet Enjoyment.
Landlord covenants that Tenant, upon
performing the terms, covenants and conditions of this Lease, shall have quiet
and peaceful possession of the Premises as against any person claiming the same
by, through or under Landlord. 

    
13. Alterations. Landlord hereby consents to
certain Tenant Improvements, on the terms and subject to the conditions of
Exhibit C.
Tenant shall not make or permit any Alterations in, on or about the Premises
without the prior written consent of Landlord, and according to plans and
specifications approved in writing by Landlord, which consent and approval shall not be
unreasonably withheld, conditioned or delayed. Except in the case of the Tenant
Improvements which are the subject of the Initial Installation, Landlord, at its
sole option, may, however, require as a condition to the granting of any such
consent, that Tenant provide to Landlord, at Tenant’s sole cost and expense, a
lien and completion bond in an amount equal to one and one-half (11⁄2) times any
and all estimated costs of any intended improvements to the Premises, to insure
Landlord against any liability for mechanics’ and materialmen’s liens and to
insure completion of the work. Except in the case of the Tenant Improvements
which are the subject of the Initial Installation, and unless otherwise agreed
in writing by the parties, Tenant shall, at its sole cost and expense, obtain
all necessary permits and governmental inspections and approvals required in
connection with any Alterations. All Alterations shall be installed at Tenant’s
sole expense (except as expressly set forth in this Lease), in compliance with
all applicable laws (including, but not limited to, The American With
Disabilities Act, and any state or local building, fire or safety codes,
ordinances or regulations), the Rules and Regulations and the CC&R’s, by
Landlord’s contractor unless otherwise agreed by the parties. All Alterations
shall be done in a good and workmanlike manner conforming in quality and design
with the Premises existing as of the Commencement Date, and shall not diminish
the value of the Project. All Alterations made by Tenant shall be and become the
property of Landlord upon installation and shall not be deemed Tenant’s Personal
Property. Notwithstanding any other provisions of this Lease, Tenant shall be
solely responsible for the maintenance and repair of any and all Alterations
made by it to the Premises. Tenant shall give Landlord written notice of
Tenant’s intention to perform any Alterations on the Premises at least twenty
(20) days prior to the commencement of such Alterations to enable Landlord to
post and record an appropriate Notice of Non-responsibility or other notice
deemed proper before the commencement of any such Alterations. 

-15- 

    
14. Surrender of the Premises. Tenant shall not be
required to restore or remove, or to pay Landlord for the restoration or removal
of, any portion of the Initial Installation (as defined by the Work Letter
attached hereto as Exhibit C) or any other improvement or alterations completed
prior to the Commencement Date of this Lease, including, without limitation, any
improvements or alterations completed or undertaken under the 2007 Lease, or
future Alterations, provided that such future Alterations are approved in
writing by Landlord in advance, such approval not to be unreasonably withheld. Except as permitted in this Lease, upon the expiration or
earlier termination of the Term, Tenant shall surrender the Premises to Landlord
in its condition existing as of the Commencement Date, normal wear and tear and
fire or other insured casualty for which Tenant is not otherwise obligated under
the provisions of Paragraph 18 to repair excepted, with all interior areas
cleaned. Any damage or deterioration of the Premises shall not be deemed
ordinary wear and tear if Tenant was responsible for maintaining the same under
the provisions of Paragraph 18 and if the same could reasonably have been
prevented by good maintenance practices by Tenant. Except as otherwise stated in
this Lease, Tenant shall leave the air lines, power panels, electrical
distribution systems, voice and data wiring, lighting fixtures, air
conditioning, window coverings, wall coverings, carpets, wall paneling,
ceilings, and plumbing on the Premises and in good operating condition. Tenant
shall prior to the expiration or termination of the Term remove all Tenant’s
Personal Property, including security wiring installed by Tenant if requested by
Landlord, and repair any damage and perform any restoration work caused or
necessitated by any such removal. If Tenant fails to remove Tenant’s Personal
Property, and such failure continues after the termination of this Lease,
Landlord may retain such property and all rights of Tenant with respect to it
shall cease, or Landlord may place all or any portion of such property in public
storage for Tenant’s account. Tenant shall be liable to Landlord for costs of
removal of Tenant’s Personal Property and storage and transportation costs of
same, and the cost of repairing and restoring the Premises, together with
interest at the Interest Rate from the date of expenditure by Landlord until
paid.

A.
Payment by Tenant. During the Term of this Lease, Tenant shall pay to Landlord,
as Rent on a monthly basis as set forth in Paragraph 5.A (ii)., one-twelfth

capital improvements described in clauses (i) and (ii) above being amortized
with interest at an annual rate of eight percent (8%) simple over the period

      this Lease.

          The Landlord shall not recover under this Section 15 or
elsewhere in this Lease any item of cost more than once.

         
C.
Adjustment.

              
(i) Projected
Increases. Prior to or at any time after the commencement of each calendar year
during the Term following the Base Year, Landlord
may provide Tenant with notice of Landlord’s reasonable estimate of the amount
by which the then current year’s Operating Expenses are projected, if at all, to
exceed the Base Year Operating Expenses (the “Projected Increase in Operating
Expenses”). Tenant shall thereafter during such year pay adjusted Monthly Rent
which shall include as the Monthly Operating Expense Reimbursement an amount
equal to one-twelfth (1/12) of Tenant’s Building Percentage multiplied by any
Projected Increase in Operating Expenses. 

-19- 

              
(ii) Accounting. Within ninety (90) days (or as soon thereafter as possible)
after the close of each calendar year after the Base Year, Landlord shall
provide Tenant a statement of (a) such year’s actual Operating Expenses, (b) the
Base Year Operating Expenses, (c) the amount, if any, by which the actual
Operating Expenses exceed the Base Year Operating Expenses (the “Actual Increase
in Operating Expenses”), (d) the amount equating to Tenant’s Building Percentage
of any Actual Increase in Operating Expenses and (e) the sum of any amounts
theretofore paid by Tenant as Monthly Operating Expense Reimbursements pursuant
to Paragraph 5.A. with respect to such year. If the amount set forth in clause
(d) above exceeds the amount set forth in clause (e) above, Tenant shall pay the
amount of such excess to Landlord within ten (10) days after receipt of
such statement, which obligation shall survive the expiration or earlier
termination of its Term of the Lease. If the amount set forth in clause (e)
above exceeds the amount set forth in clause (d) above, Landlord shall, within
thirty (30) days after the date of such statement, credit the amount of such
excess against the next accruing payment(s) of Monthly Operating Expense
Reimbursements or reimburse Tenant for same if this Lease has terminated prior
to the date such determination is made. If Tenant disputes the amount of the
Actual Increase in Operating Expenses stated in said statement, Tenant may
designate, within sixty (60) days after receipt of such statement, an
independent certified public accountant to inspect Landlord’s records, at
Tenant’s sole cost. Tenant is not entitled to request that inspection, however,
if Tenant is then in Default under this Lease. The accountant shall be a member
of a nationally recognized accounting firm and shall not charge a fee based on
the amount of the Actual Increase in Operating Expenses that the accountant is
able to save Tenant by the inspection. Such accountant and Tenant shall, at
Landlord’s option, prior to the occurrence of any such inspection, execute a
confidentiality agreement in form reasonably acceptable to the parties thereto
in which such accountant and Tenant agree to maintain Landlord’s books and
records and the results of such inspection in confidence. Tenant shall give
reasonable notice to Landlord of the request for inspection, and the inspection
shall be conducted in Landlord’s offices at a
reasonable time or times. If, after that inspection, Tenant still disputes the
Actual Increase in Operating Expenses, a certification of the proper amount
shall be made, at Tenant’s expense, by an independent certified public
accountant mutually acceptable to Landlord and Tenant. That certification shall
be final and conclusive. If any such certification demonstrates that Landlord’s
statement overstated the amount of the Actual Increase in Operating Expenses by
5% or more, Landlord shall credit or reimburse the reasonable cost of the audit
not to exceed $1,500.00 and the amount of Tenant’s Building Percentage thereof
against the next accruing payment(s) of Monthly Operating Expense Reimbursements
or reimburse Tenant for same if this Lease has terminated prior to the date such
determination is made. Such reimbursement is Tenant’s sole remedy for any error
in such statement from Landlord. 

              
(iii) Proration. Tenant’s liability to pay Tenant’s Building Percentage of
Operating Expenses in excess of Base Year Operating Expenses shall be prorated
on the basis of a 365-day year to account for any fractional portion of a year
included at the commencement or expiration of the term of this Lease.

              
(iv) Not Fully
Occupied. Notwithstanding any other provision to the contrary, it is agreed that if
the Building, in total, is less than ninety-five percent (95%) occupied during
all or any portion of any calendar year (including, without limitation, the Base
Year), an adjustment shall be made in calculating the Operating Expenses for the
Project for such year so that Tenant’s Percentage of Operating Expenses in
excess of the Base Year Operating Expenses shall be equivalent to the Operating
Expenses calculated as though the Building, in total, had been ninety-five
percent (95%) occupied during the entirety of such year. 

              
(v) Survival. Landlord and Tenant’s
obligation to pay for or credit any increase or decrease in payments pursuant to
this Paragraph shall survive the expiration or termination of the Term of this
Lease. 

-20- 

         
D.
Failure to Pay or
Reimburse. Failure of Tenant to pay
or by Landlord to reimburse any of the charges required to be paid or reimburse
under this Paragraph 15. shall constitute a breach of this Lease and Landlord’s
remedies shall be as specified in Paragraph 29.B. 

    
16.
Taxes and Assessments.

repairs which are otherwise Tenant’s responsibility hereunder.

-23- 

              
(iv) Notice of
Repairs Needed. Landlord shall not be liable for any failure to make any of
the repairs or to perform any maintenance unless the failure shall persist for
an unreasonable time after written notice of the need of the repairs or
maintenance is given to Landlord by Tenant. For any HVAC failure affecting the
server room on the Premises or other failure involving life safety systems or
security, Landlord will make best efforts to respond within twenty-four (24)
hours. For any other repairs or maintenance, an “unreasonable amount of time”

EXHIBIT
F.
Landlord shall further have the right to enter
upon the Premises, as provided in Paragraph 21,
for the purpose of installing, maintaining, repairing, adjusting and making

electrical, telephone, and cable TV) serving the Premises or other spaces in the
Building or for gaining access to the structural portions of the Building and
making alterations thereto for the benefit of Tenant, Landlord or other
occupants of the Building. No such entry shall be considered a constructive or
actual eviction of Tenant, and Landlord shall have no liability to Tenant
therefor, provided that Landlord shall use commercially reasonable efforts to
minimize interference with Tenant’s operations. 

         
C.
Waiver.
Provided that repairs are made by

provisions of all laws, statutes or ordinances, including Sections 1932(1),
1932(2), 1933(4), 1941 and 1942 of the California Civil Code and any similar or
successor law, which might now or at any time hereafter otherwise afford Tenant

due under this Lease. 

         
D.
Compliance with Governmental
Regulations. Subject to the provisions of Paragraphs 10 and 11, Tenant shall, at its
cost comply with, including the making by Tenant of any Alteration to the

other than Tenant’s trade fixtures, furniture (not including  furniture owned by Landlord and used by Tenant) and
equipment, which are  installed or constructed upon or attached to the Premises by either Landlord or  Tenant shall become a
part of the realty and belong to Landlord. If Tenant is  not then in Default, Tenant may, at the termination of this Lease,
or at any  other time, remove from the Premises all trade fixtures, furniture (not including
furniture owned by Landlord and used by Tenant),  equipment and other Tenant’s Personal Property not permanently affixed
to the  Premises. Upon removal, Tenant shall restore the Premises to its original  condition at the time of occupancy, Tenant

to the provisions of Paragraph 25.  

-25- 

     20. Liens.
Tenant shall keep the Project free from any
liens arising out of any work performed, materials furnished or obligations
incurred by or on behalf of Tenant and shall defend, indemnify and hold the
Project, Landlord and Landlord’s Agents free and harmless from and against any

such lien or claim of lien. Tenant shall cause any such lien imposed to be
released of record by payment or posting of a proper bond acceptable to Landlord

-27- 

         
C.
Landlord’s Insurance. During the Term
Landlord shall maintain “All Risk” property insurance (including, at Landlord’s

-28- 

          H. 
Landlord’s
Disclaimer. Landlord and Landlord’s Agents shall not be liable for any

plaster, glass, tile or sheetrock, steam, gas, electricity, water or rain which
may leak from any part of the Project, or from the pipes, appliances or plumbing
works therein or from the roof, street or subsurface or whatsoever, unless

proceeds actually received. Tenant and Landlord shall, upon obtaining policies
of insurance required hereunder, give notice to the insurance carrier that the
foregoing mutual waiver of subrogation is contained in this Lease and Tenant and
Landlord shall cause each insurance policy obtained by such party to provide
that the insurance company waives all right of recovery by way of subrogation

25. 
Damage or Destruction.

         
A.
Partial Damage — Insured. If the Premises or
the Building are damaged by any casualty which is covered under the “All-Risk”
insurance carried by Landlord pursuant to Paragraph 23.C., then Landlord shall
restore the damage, provided insurance proceeds are available to pay the full
cost of restoration and provided such restoration can be completed within one
hundred eighty (180) days after the commencement of the work in the reasonable
opinion of Landlord. In such event this Lease shall continue in full force and
effect, except that Tenant shall be entitled to a proportionate reduction of
Monthly Rent while such restoration for which Landlord is obligated hereunder
takes place, such proportionate reduction to be based upon the extent to which
the damage and restoration efforts interfere with Tenant’s use of the Premises.

-29- 

         
B.
Partial Damage — Uninsured. If the Premises or
the Building is damaged by a risk not covered by Landlord’s insurance, or the
available proceeds of insurance are less than the cost of restoration, or if the
restoration cannot be completed within one hundred eighty (180) days after
the commencement of work, in the reasonable opinion of Landlord, then Landlord
shall have the option either to: (i) repair or restore such damage, this Lease
continuing in full force and effect, but the Monthly Rent to be proportionately
abated as provided in Paragraph 25.A.; or (ii) give notice to Tenant at any time
within thirty (30) days after such damage terminating this Lease as of a date to
be specified in such notice, which date shall be not less than thirty (30) nor
more than sixty (60) days after giving such notice. If notice of termination is
given, this Lease shall expire and all interest of Tenant in the Premises shall
terminate on the date specified in the notice and the Monthly Rent shall be
reduced in proportion to the extent, if any, to which the damage interferes with
the use of the Premises by Tenant and any prepaid Monthly Rent and Operating
Expenses shall be refunded to Tenant to the same extent. All insurance proceeds
for the Premises shall be payable solely to Landlord, and Tenant shall have no
interest in the proceeds. 

          C. Total
Destruction. If the Premises or the Building is totally destroyed or the
Premises or Building, as the case may be, cannot be restored as required herein
under applicable laws and regulations or due to the presence of hazardous
factors such as earthquake faults, chemical waste and similar dangers,
notwithstanding the availability of insurance proceeds, this Lease shall be
terminated effective the date of the damage. 

          D.
Tenant’s
Election. If the Premises are damaged by any casualty, or if any portion of the
Outside Area is damaged by a casualty to such an extent that the Premises is no
longer useable by Tenant, in Tenant’s reasonable opinion, and if, in Landlord’s
reasonable opinion, such casualty cannot be repaired or restored within one
hundred eighty (180) days after commencement of such work, then Tenant may, by
written notice delivered to Landlord at any time within thirty (30) days after
such damage, terminate this Lease as of the future date specified in such
notice, which date shall not be less than thirty (30) nor more than sixty (60)
days after the date of Tenant’s delivery of such notice. If notice of
termination is so given, this Lease shall expire and all interests of Tenant and
the Premises shall terminate on the date specified in the notice and the Monthly
Rent shall be reduced in proportion to the extent, if any, to which the damage
interferes with the use of the Premises by Tenant and any prepaid Monthly Rent
and Operating Expenses shall be refunded to Tenant to the same extent. All
insurance proceeds for the Premises shall be payable to Landlord, and Tenant
shall have no interest in the proceeds. 

          E. Landlord’s
Obligations. Landlord shall not be required to insure against or repair any injury or
damage by fire or other cause, or to make any restoration or replacement of any
paneling, decorations, partitions, railings, floor coverings, office fixtures or
other items which are Tenant Improvements, Alterations or Personal Property
installed in the Premises by Tenant or at the direct or indirect expense of
Tenant. Tenant shall be required at Tenant’s sole cost and expense, separately
to insure the same and promptly to restore or replace same in the event of
damage. Except for any abatement of Monthly Rent relating to the plan of
restoration of damage for which Landlord is obligated to repair hereunder,
Tenant shall have no claim against Landlord for any damage suffered by reason of
any such damage, destruction, repair or restoration; nor shall Tenant have the
right to terminate this Lease as the result of any statutory provision now or
hereafter in effect pertaining to the damage and destruction of the Premises,
except as expressly provided herein.

-30- 

          F.
Damage Near End of
Term. Anything herein to the contrary notwithstanding, if more than fifty
percent (50%) of the Building is destroyed or damaged during the last twelve
(12) months of the Term, then either Tenant or Landlord may, at its option,
cancel and terminate this Lease as of the date of the occurrence of the damage.
If neither such party elects to terminate this Lease, the repair of the damage
shall be governed by the other provisions of this Paragraph 25. If this Lease is
terminated, Landlord may keep all the insurance proceeds resulting from the
damage, except for the proceeds which specifically insured Tenant’s Personal
Property.

     26. Condemnation.

          A. Total Taking —
Termination. If title to all of the Premises or so much thereof is taken or
appropriated for any public or quasi-public use under any statute or by right of
eminent domain so that reconstruction of the Premises will not, in Landlord’s
and Tenant’s mutual opinion, result in the Premises being reasonably suitable
for Tenant’s continued occupancy for the uses and purposes permitted by this
Lease, this Lease shall terminate as of the date that
possession of the Premises or part thereof be taken. A sale by Landlord to any
authority having the power of eminent domain, either under threat of
condemnation or while condemnation proceedings are pending, shall be deemed a
taking under the power of eminent domain for all purposes of this Paragraph.

          B. Partial
Taking. If any part of the Premises or the Building is taken and the remaining
part is reasonably suitable for Tenant’s continued occupancy for the purposes
and uses permitted by this Lease, this Lease shall, as to the part so taken,
terminate as of the date that possession of such part of the Premises or
Building is taken. If the Premises is so partially taken the Rent and other sums
payable hereunder shall be reduced in the same proportion that Tenant’s use and
occupancy is reduced. 

          C. No Apportionment of
Award. No award for any partial or entire taking shall be apportioned. Tenant
assigns to Landlord its interest in any award which may be made in such taking
or condemnation, together with any and all rights of Tenant arising in or to the
same or any part thereof. Nothing contained herein shall be deemed to give
Landlord any interest in or require Tenant to assign to Landlord any separate
award made to Tenant for the taking of Tenant’s Personal Property, for the
interruption to Tenant’s business, or its moving costs, or for the loss of its
good will. 

          D. Temporary
Taking. No temporary taking of the Premises shall terminate this Lease or give
Tenant any right to any abatement of Rent. Any award made to Tenant by reason of
such temporary taking shall belong entirely to Tenant and Landlord shall not be
entitled to share therein. Each party agrees to execute and deliver to the other
all instruments that may be required to effectuate the provisions of this
Paragraph.

-31- 

     27. Assignment and Subletting.

          A. Landlord’s
Consent. Except as permitted by Paragraph 27.I hereof, Tenant shall not enter into
a Sublet without Landlord’s prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed. Except as permitted by Paragraph
27.I, any attempted or purported Sublet without Landlord’s prior written consent
shall be void and confer no rights upon any third person and, at Landlord’s
election, shall terminate this Lease. Each Subtenant shall agree in writing, for
the benefit of Landlord, to assume, to be bound by, and to perform and observe
the terms, covenants and conditions of this Lease (with the exception of Monthly
Rent) to be performed and observed by Tenant. Every Sublet shall recite that it
is and shall be subject and subordinate to the provisions of this Lease, and
that the termination of this Lease shall constitute a termination (at the option
of the Landlord) of every such Sublet. Notwithstanding anything contained herein, (i) Tenant shall not be
released from personal liability for the performance of any of the terms,
covenants and conditions of this Lease by reason of Landlord’s consent to a
Sublet unless Landlord specifically grants such release in writing (it being
agreed that Landlord has no obligation to do so), and (ii) the parties agree
that it shall be reasonable for Landlord to withhold its consent to any proposed
Sublet when the proposed Subtenant is an occupant of the Property or is a third
party which is already involved in negotiations with Landlord to lease space in
the Project. Without limiting the generality of Landlord’s discretion in
determining whether it is reasonable to withhold consent for any requested
Sublet, it shall be deemed reasonable for Landlord to withhold such consent if
the proposed Subtenant would use the Premises for any use other than for general
office purposes. 

          B. Information to be
Furnished. If Tenant desires at any time to Sublet the Premises or any portion
thereof, it shall first notify Landlord of its desire to do so and shall submit
in writing to Landlord: (i) the name of the proposed Subtenant; (ii) the nature
of the proposed Subtenant’s business to be carried on in the Premises; (iii) the
terms and provisions of the proposed Sublet and a copy of the proposed Sublet
form containing a description of the subject premises; and (iv) such financial
information, including financial statements, as Landlord may reasonably request
concerning the proposed Subtenant. If Tenant requests Landlord’s consent to a
proposed Sublet, Tenant shall pay to Landlord, whether or not consent is
ultimately given, Landlord’s reasonable attorneys’ fees incurred in connection
with such request up to a maximum of $1,500.00. 

          C. Landlord’s
Alternatives. Except in the case of a Sublet permitted by Paragraph 27.I, at
any time within ten (10) business days after Landlord’s receipt of all the
information specified in Paragraph 27.B., Landlord may, by written notice to
Tenant, elect: (i) to lease for its own account the portion thereof of the
Premises so proposed to be Sublet by Tenant, upon the same terms as those
offered to the proposed subtenant but on a form acceptable to Landlord; (ii) to
terminate this Lease as it relates to the portion of the Premises so proposed to
be Sublet by Tenant as of the later of (x) the proposed effective date of such
Sublet or (y) thirty (30) days after the date Landlord is in receipt of the
information specified in Paragraph 27.B.; (iii) to consent to the Sublet by
Tenant; or (iv) to refuse its consent to the Sublet. Landlord’s failure to
deliver such notice of election within such 10-business day period shall be
deemed Landlord’s consent to such Sublet.

-32-

          If Landlord consents to the Sublet, Tenant may thereafter
enter a valid Sublet of the Premises or portion thereof, upon the terms and
conditions and with the proposed Subtenant set forth in the information
furnished by Tenant to Landlord pursuant to Paragraph 27.B. provided, however,
that fifty percent (50%) of any excess of (I) the Subrent over (II) (A) the
Monthly Rent required to be paid by Tenant hereunder, (B) Tenant’s reasonable
attorneys’ fees and brokerage commissions, in each case, with the total of such amounts under this clause (B) applied on an
amortized basis over the term of the Sublet, and (C) and any then unamortized
value of the applicable Tenant Improvements, to the extent not reimbursed out of
the TI Allowance, applied on an amortized basis over the remainder of the Term,
shall be paid to Landlord as and when received by Tenant. As used immediately
above, the term “applicable Tenant Improvements” means the Tenant Improvements
allocable to the space that is subject to the applicable Sublet, based upon
rentable square footage. 

          D. Proration. If a portion of the
Premises is Sublet, the pro rata share of the Monthly Rent attributable to such
partial area of the Premises shall be determined by Landlord by dividing the
Monthly Rent payable by Tenant hereunder by the total rentable square footage of
the Premises and multiplying the resulting quotient (the per rentable square
foot rent) by the number of rentable square feet of the Premises which are
Sublet. 

          E. Executed
Counterpart. No Sublet shall be valid nor shall any Subtenant take possession of the
Premises until an executed counterpart of the Sublet agreement has been
delivered to Landlord. 

          F. Surrender of
Lease. The voluntary or other surrender of this Lease by Tenant, or a mutual
cancellation thereof, shall not work a merger, and shall, at the option of
Landlord, terminate all or any existing Sublets, or may, at the option of
Landlord, operate as an assignment to it of any or all such Sublets. 

          G. No
Mortgages. Tenant shall not pledge, hypothecate or encumber this Lease or Tenant’s
interest herein or in the Premises in any manner, including without limitation,
by means of any mortgage, deed of trust, security interest or assignment for
security purposes, and any such attempted pledge, hypothecation or encumbrance
shall be void and constitute a Default under this Lease. 

          H. Effect of
Default. Notwithstanding any provision of this Paragraph 27 to the contrary, in
the event of the occurrence of any uncured Default by Tenant in the performance
of any term or condition of this Lease, any right of Tenant at such time to seek
to Sublet this Lease pursuant to this Paragraph 27 and any obligations of
Landlord to review any proposed Sublet or exercise its rights under Paragraph
27.C. above shall be suspended, and any applicable period for review or action
by Landlord shall be tolled, until such Default is fully cured of no force or
effect.

-33-

          I.
Permitted
Transfers. Notwithstanding anything to the contrary contained in this Lease, Tenant,
without Landlord’s prior written consent, may sublet the Premises or assign this
Lease to: (i) a subsidiary, affiliate, division or entity controlling,
controlled by or under common control with Tenant; (ii) a successor entity
related to Tenant by merger, acquisition, consolidation, nonbankruptcy
reorganization or government action; or (iii) a purchaser of substantially all
of Tenant’s assets (collectively “Permitted Transferees”); provided Tenant
enters into such a transaction in good faith and not for the purpose of
indirectly entering into a Sublet of this Lease with a person or entity other
than a Permitted Transferee through a step transaction or otherwise. Tenant
shall not be required to obtain Landlord’s consent thereof, nor shall provisions
of Paragraph 27.C. hereof apply; in no event shall such assignment or sublease
release Tenant from any liability for the performance of the obligations under
this Lease, unless Landlord shall have released Tenant In writing (it being
agreed that Landlord has not obligation to do so). Further, the requirements
contained in the third and fourth sentences of Paragraph 27.A. shall apply to
all such transfer. 

     28. Sale Lease-Back.
Tenant acknowledges that Landlord may, at some time in the future, finance the
Property by means of a sale and lease back transaction (“Sale Lease-Back
Transaction”) in which Landlord would transfer its interest in the Project to a
financing party, as buyer, and in which such buyer would lease the Project back
to Landlord. Tenant agrees that, in the event of any such Sale Lease-Back
Transaction, this Lease shall automatically become subordinate to the leasehold
interest created by the lease between such buyer and Landlord (the “Master
Lease”). In such event, this Lease shall thereafter be a sublease below the
Master Lease. Notwithstanding the automatic effect of such subordination, Tenant
agrees to execute any documentation reasonably required by such buying party to
evidence such subordination. Notwithstanding the foregoing, any such
subordination of this Lease shall be subject to the requirement that such buying
entity shall have agreed, in form reasonably acceptable to Tenant, that in the
event of any termination of the Master Lease because of the Default of Landlord
thereunder or because of the consensual agreement of Landlord and such buying
party, this Lease shall automatically become a direct lease between such buying
party, as landlord, and Tenant, as tenant. 

     29. Default.

          A. Tenant’s
Default. A default under this Lease by Tenant shall exist if any of the following
events shall occur (as applicable, a “Default”):

               (i) If Tenant fails to pay Rent or any other sum required to be paid
hereunder within five (5) days after the date of Tenant’s receipt of written
notice from Landlord that such amount was not received when due; or

-34-

               (ii)
If Tenant fails to perform any term, covenant or condition of this Lease except
those requiring the payment of money, and Tenant shall have failed to cure such
breach within twenty (20) days after written notice from Landlord; provided,
however, that if such failure by its nature cannot reasonably be cured within
the twenty (20) day period, then Tenant shall not be in Default if Tenant
promptly commences the performance of such cure within the twenty (20) day
period and diligently thereafter prosecutes the same to completion; or

               (iii)
If Tenant shall have abandoned the Premise; or 

               (iv)
In the event of a general assignment by Tenant for the benefit of creditors; the
filing of any voluntary petition in bankruptcy by Tenant or the filing of an
involuntary petition by Tenant’s creditors, which involuntary petition remains
undischarged for thirty (30) days; the employment of a receiver to take
possession of substantially all of Tenant’s assets or any part of the Premises,
if such receivership remains undissolved for thirty (30) days after creation
thereof; the attachment, execution or other judicial seizure of all or
substantially all of Tenant’s assets or any part of the Premises, if such
attachment or other seizure remains undismissed or undischarged for thirty (30)
days after the levy thereof; the admission by Tenant in writing of its inability
to pay its debts as they become due; the filing by Tenant of a petition seeking
any reorganization or arrangement, composition, readjustment, liquidation,
dissolution or similar relief under any present or future statute, law or
regulation; the filing by Tenant of an answer admitting or failing timely to
contest a material allegation of a petition filed against Tenant in any such
proceeding; or, if within thirty (30) days after the commencement of any
proceeding against Tenant seeking any reorganization or arrangement,
composition, readjustment, liquidation, dissolution or similar relief under any
present or future statute, law or regulation, such proceeding shall not have
been dismissed; or 

               (v)
The occurrence of any other event specifically stated to be a Default under the
provisions of this Lease. 

          B. Remedies. Upon a Default,
Landlord shall have the following remedies, in addition to all other rights and
remedies provided by law or otherwise provided in this Lease, to which Landlord
may resort cumulatively or in the alternative: 

               (i)
Landlord may continue this Lease in full force and effect, and this Lease shall
continue in full force and effect as long as Landlord does not terminate this
Lease, and Landlord shall have the right to collect Rent when due. During the
period Tenant is in Default, Landlord may enter the Premises and relet it, or
any part of it, to third parties for Tenant’s account, provided that any Rent in
excess of the Monthly Rent due hereunder shall be payable to Landlord. Tenant
shall be liable immediately to Landlord for all costs Landlord incurs in
reletting the Premises or any part thereof, including, without limitation,
broker’s commissions, expenses of cleaning and redecorating the Premises
required by the reletting and like costs. Reletting may be for a period shorter
or longer than the remaining Term of this Lease. Except as set forth in
Paragraph 29.C., no act by Landlord other than giving written notice to Tenant
shall terminate this Lease.

-35-

               (ii) Landlord may by written notice terminate Tenant’s right
to possession of the Premises at any time and relet the Premises or any part
thereof. Acts of maintenance, efforts to relet the Premises or the appointment
of a receiver on Landlord’s initiative to protect Landlord’s interest under this
Lease shall not constitute a termination of Tenant’s right to possession. On
termination, Landlord has the right to remove all Tenant’s Personal Property and
store same at Tenant’s cost and to recover from Tenant: 

          (a)
the worth at the time of award of the unpaid Rent which had been earned at the
time of termination including interest at the Interest Rate;

          (b)
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 Tenant proves could have been reasonably
avoided, including interest at the Interest Rate;

          (c)
the worth at the time of award of the amount by which 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 Tenant proves could be reasonably avoided,
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of award plus one percent (1%); 

          (d)
any other amount necessary to compensate Landlord for all the detriment
proximately caused by Tenant’s failure to perform its obligations under this
Lease, including without limitation the following: (i) all expenses for
repairing or restoring the Premises, (ii) all brokers’ fees, advertising costs
and other expenses of repairing or restoring the Premises, (iii) all expenses in
retaking possession of the Premises, and (iv) reasonable attorneys’ fees, expert
witness fees and court costs; and 

          (e) as
used in subparagraphs (a) through (c) above, the term “time of award” shall mean
the date of entry of a judgment or award against Tenant in an action or
proceeding arising out of Tenant’s breach of this Lease. 

          Tenant
waives redemption or relief from forfeiture under California Code of Civil
Procedure Sections 1174 and 1179, or under any other present or future law, in
the event Tenant is evicted or Landlord takes possession of the Premises by
reason of any Default of Tenant hereunder. 

               (iii)
Landlord may, with or without terminating this Lease, re-enter the Premises and
remove all persons and property from the Premises; such property may be removed
and stored in a public warehouse or elsewhere at the cost of and for the account
of Tenant. No re-entry or taking possession of the Premises by Landlord pursuant
to this Paragraph shall be construed as an election to terminate this Lease
unless a written notice of such intention is given to Tenant.

-36-

          C.
Landlord’s
Default. Landlord shall not be deemed to be in default in the performance of any
obligation required to be performed by it hereunder unless and until it has
failed to perform such obligation within twenty (20) days after receipt of
written notice by Tenant to Landlord specifying the nature of such default;
provided, however, that if the nature of Landlord’s obligation is such that more
than twenty (20) days are required for its performance, then Landlord shall not
be deemed to be in default if it shall commence such performance within such
twenty (20) day period and thereafter diligently prosecute the same to
completion. In the case of any uncured default by Landlord, Tenant shall have
the following remedies, in addition to all other rights and remedies provided by
law or otherwise provided in this Lease, to which Tenant may resort cumulatively
or in the alternative: 

               i. If Tenant is not in Default,
Tenant may continue this Lease in full force and effect, provided that in such
case Tenant shall be entitled to recover from Landlord any reasonable cost
incurred by Tenant that is in excess of the amount of the Rent which would have
been incurred by Tenant had no uncured breach by Landlord occurred, including
interest at the Interest Rate. 

               ii. In the case of any default
under this Lease (whether by Landlord or Tenant) each party shall make best
efforts to mitigate any losses or damages arising therefrom. 

               iii. In the case of expiration or
early termination of this Lease, those provisions of this Lease which expressly
continue in operation after termination or expiration shall continue in full
force and effect according to their terms.

     30. Subordination. This Lease is and shall automatically be subject and
subordinate to all mortgages and deeds of trust (collectively, “Encumbrance”)
which may now or hereafter affect the Premises, to the CC&R’s and to all
renewals, modifications, consolidations, replacements and extensions thereof;
provided, however, (i) if the holder or holders of any such Encumbrance
(“Holder”) shall require that this Lease be prior and superior thereto, then
upon written notice from Holder to Tenant this Lease shall be automatically
prior and superior to the lien of such Encumbrance without regard to the
sequence of recordation, and (ii) such subordination is subject to the
requirement that such Holder agree not to disturb Tenant’s rights under this
Lease, so long as Tenant is not in Default under the provisions of this Lease;
Within ten (10) days after Landlord or Holder’s written request, Tenant shall
execute any and all documents requested by Landlord or Holder to further
effectuate and evidence such subordination of this Lease to any lien of the
Encumbrance or to evidence the Holder’s election that this Lease be prior and
senior to the Encumbrance. Notwithstanding anything to the contrary set forth in
this Paragraph, Tenant hereby attorns and agrees to attorn to the Holder and any
person purchasing or otherwise acquiring the Premises at any sale or other
proceeding or pursuant to the exercise of any other rights, powers or remedies
under such Encumbrance, which obligation to attorn shall survive any foreclosure
of any Encumbrance; and Tenant agrees within ten (10) days after request of
Holder or any such other person to execute an attornment agreement recognizing
Holder or such other person as Landlord under this Lease and acknowledging that
this Lease is and shall remain in full force and effect and binding upon Tenant
notwithstanding any foreclosure of such Encumbrance. Tenant acknowledges that,
as of the date of this Lease, the Property is subject to the lien of a deed of
trust for the benefit of Wells Fargo Bank, National Association
(“Wells”).

-37- 

     31.
Notices. Every notice to be given
by any party to any other party with respect hereto, shall be in writing and
shall not be effective for any purpose unless the same shall be delivered to the
addressee personally, by a reputable express delivery service, a recognized
overnight air courier service, or United States certified mail, return receipt
requested, addressed to the respective parties at the addresses set forth in
section C.11. of the Information Sheet, or to such other address as either party
may from time to time designate by notice to the other given in accordance with
this Paragraph. All notices shall be effective (i) when delivered locally by
hand or by a reputable express delivery service (ii) one business day after
deposit with a recognized overnight air courier service or (iii) five business
days after having been sent by certified mail, return receipt requested.

     32.
Attorneys’
Fees. In the event Landlord engages an attorney to pursue the recovery of any
Rent owed by Tenant hereunder (whether or not any action or legal proceeding is
ultimately filed) or if either party brings any action or legal proceeding for
damages for an alleged breach of any provision of this Lease, to recover Rent or
other sums due, to terminate the tenancy of the Premises or to enforce, protect
or establish any term, condition or covenant of this Lease or right of either
party, the prevailing party shall be entitled to recover as a part of such
action or proceedings, or in a separate action brought for that purpose,
reasonable attorneys’ fees and costs, including expert witness fees (and without
regard to whether or not such action or proceedings are pursued to judgment).

     33.
Estoppel
Certificates. Tenant shall within ten (10) business days following written
request by Landlord: 

               (i)
Execute and deliver to Landlord any documents whose content Tenant agrees is
true and correct, including estoppel certificates, in the form prepared by
Landlord (a) certifying the date of commencement of this Lease, (b) certifying
that this Lease is unmodified and in full force and effect or, if modified,
stating the nature of such modification and certifying that this Lease, as so
modified, is in full force and effect, (c) stating the dates to which Rent and
any other amounts payable hereunder have been paid and the amount of any
unforfeited security deposit then held by Landlord, (d) certifying that no
Defaults exist as of such date, or, if there are any Defaults, stating the
nature of such Defaults, (e) acknowledging that there are not, to Tenant’s
knowledge, any uncured defaults on the part of Landlord, or, if there are
uncured defaults on the part of the Landlord, stating the nature of such uncured
defaults, (f) acknowledging that Tenant does not have any claim or right of
offset against Landlord (or if Tenant does have any such claim or right of
offset, the nature of such claim or right of offset), and (g) setting forth such
other matters as may reasonably be requested by Landlord. Tenant’s failure to
deliver an estoppel certificate in the form provided or as modified by Tenant to
correct any errors or inaccuracies within ten (10) business days after delivery
of Landlord’s written request therefor shall be conclusive upon Tenant (a) that
this Lease is in full force and effect, without modification except as may be
represented by Landlord, (b) that there are now no uncured defaults in
Landlord’s performance, (c) that no Rent has been paid in advance and no
security deposit is held by Landlord, (d) that Tenant has no claims or rights of
offset against Landlord, (e) that no Defaults then exist, and (f) that such
other matters as were set forth in such estoppel certificate as prepared by
Landlord are true and correct; provided further, that such failure shall
constitute a breach of this Lease and Landlord’s remedies shall be as specified
in Section 29.B.

-38- 

               (ii)
Deliver to Landlord or direct Landlord to where it may obtain the current
financial statements of Tenant, and financial statements of the two (2) years
prior to the current financial statements year, with an opinion of a certified
public accountant, including a balance sheet and profit and loss statement for
the most recent prior year, all prepared in accordance with generally accepted
accounting principles consistently applied. To the extent such statements have
not previously been made public by Tenant, Landlord agrees to maintain any such
statements in confidence other than to disclose them to the applicable lender or
potential buyer who has requested them, or as may be required by law.

     34.
Transfer of the Project by
Landlord. In the event of any conveyance of the Project or the Building and
assignment by Landlord of this Lease, Landlord shall be and is hereby entirely
released from all liability under any and all of its covenants and obligations
contained in or derived from this Lease occurring or accruing after the date of
the conveyance and assignment, and Tenant agrees to attorn to such transferee,
except in the event of a Sale Lease-Back Transaction, in which event this Lease
will remain in full force and effect as a sublease between Landlord and Tenant
as contemplated in Paragraph 28.

     35.
Landlord’s Right to Perform
Tenant’s Covenants. If Tenant fails to make any payment or perform any other act
on its part to be made or performed under this Lease, Landlord after fifteen
(15) days’ written notice may, but shall not be obligated to, and without
waiving or releasing Tenant from any obligation of Tenant under this Lease, make
such payment or perform such other act to the extent Landlord may deem
desirable, and in connection therewith, pay expenses and employ counsel. All
sums so paid by Landlord and all penalties, interest and costs in connection
therewith shall be due and payable by Tenant on the next business day after
Landlord’s delivery to Tenant of written notice of any such payment by Landlord,
together with interest thereon at the Interest Rate from such date to the date
of payment by Tenant to Landlord, plus collection costs and reasonable
attorneys’ fees. Landlord shall have the same rights and remedies for the
nonpayment thereof as in the case of Default in the payment of Rent.

-39-

     36.
Tenant’s Remedy. The obligations of
Landlord or Landlord’s Agents under this Lease do not and shall not constitute
personal obligations of Landlord or Landlord’s Agents , and Tenant agrees that
it shall look solely to the real estate that is the subject of this Lease and
any related insurance, and to no other assets of Landlord or Landlord’s Agents,
for satisfaction of any liability that may now or hereafter arise in respect of
this Lease and will not seek recourse against Landlord or Landlord’s Agents or
any of their personal assets of Landlord or Landlord’s Agents for satisfaction
of any liability that may now or hereafter arise in respect of this Lease.

     37.
Mortgagee
Protection. If Landlord defaults under this Lease, Tenant shall, if earlier requested
by Landlord or any lender with respect to the Project, notify by registered or
certified mail to any beneficiary of a deed of trust or mortgagee of a mortgage
covering the Premises and offer such beneficiary or mortgagee a reasonable
opportunity to cure the default, including time to obtain possession of the
Premises by power of sale or a judicial foreclosure, if such should prove
necessary to effect a cure. 

     38.
Brokers. Tenant warrants and
represents that it has had no dealings with any real estate broker or agent in
connection with the negotiation of this Lease, except for the broker(s)
specified in section C.10. of the Information Sheet, and that it knows of no
real estate broker or agent who is or might be entitled to a commission in
connection with this Lease. Landlord shall pay any commission or other
compensation owing to such specified broker(s) in section C.10. pursuant to
their separate written agreement. Tenant agrees to defend, indemnify and hold
Landlord and its Agents free and harmless from and against any and all
liabilities or expenses, including reasonable attorneys’ fees and costs, arising
out of or in connection with claims made by any broker or individual not
specified in section C.10. of the Information Sheet for commissions or fees
resulting from Tenant’s dealings with such other broker or individual.

     39.
Acceptance. Delivery of this
Lease, duly executed by Tenant, constitutes an offer to lease the Premises, and
under no circumstances shall such delivery be deemed to create an option or
reservation to lease the Premises for the benefit of Tenant. This Lease shall
only become effective and binding upon full execution hereof by Landlord and
delivery of a signed copy to Tenant. 

     40.
Recording. Neither party shall
record this Lease nor a short form memorandum thereof. 

     41.
Modifications for
Lender. If, in connection with obtaining financing for the Project, or any
portion thereof, Landlord’s lender shall request reasonable modifications to
this Lease as a condition to such financing, Tenant shall not unreasonably
withhold, delay or defer its consent thereto, provided such modifications do not
materially adversely affect Tenant’s rights hereunder. 

-40-

     42.
Parking. Tenant shall have
the right to park at no cost in the Project’s parking facilities in common with
Landlord’s employees and the other tenants of the Building (except for those
parking spaces that have been reserved for Landlord, other tenants of the
Project, handicapped parking and certain parking spaces designated for
Landlord’s company vehicles and contractor vehicles) upon terms and conditions,
as may from time to time be reasonably established by Landlord but in any case
free of charge and in accordance with any parking control or monitoring devices
from time to time installed or implemented by Landlord. Tenant shall not
overburden the parking facilities and shall not use more than three (3)
non-reserved, non-designated parking space per one thousand (1,000) rentable
square feet of the Premises. Tenant also agrees to cooperate with Landlord and
other tenants in the use of the parking facilities. Landlord reserves the right,
in its discretion, to allocate and assign parking spaces among Tenant and the
other tenants or to restrict the use of certain parking spaces for certain
tenants and to install or otherwise implement parking control or monitoring
devices for the parking facilities. Tenant shall establish and maintain during
the Term hereof a program to encourage maximum use of public transportation by
personnel of Tenant employed on the Premises, including without limitation, the
distribution to such employees of written materials explaining the convenience
and availability of public transportation facilities adjacent or proximate to
the Building, staggering working hours of employees, and encouraging use of such
facilities, all at Tenant’s sole reasonable cost and expense. Tenant agrees to
comply with any lawful regulation or ordinance of the City of Menlo Park or the
County of San Mateo respecting transportation management in those jurisdictions,
related to the conduct of Tenant’s business within the Premises. 

     43.
Use of Property Name
Prohibited. Tenant shall not employ the term “149 Commonwealth Drive” in the name or
title of its business or occupation without Landlord’s prior written consent.

     44.
Interest. Any Rent or other
amount not paid by Tenant to Landlord when due hereunder shall bear interest at
the lesser of (i) the rate of twelve percent (12%) per annum or (ii) the maximum
rate permitted by applicable law (with such rate of interest sometimes referred
to herein as the “Interest Rate”) from the date due until paid. 

     45.
Quitclaim. Upon any termination
of this Lease, Tenant, at Landlord’s request, shall execute, have acknowledged
and deliver to Landlord a quitclaim deed for all Tenant’s interest in the
Project. 

     46.
Security. 

          A.

               (i)
To change the name, address or title of the Project or Building upon not less

-41-

               (ii) To, at Tenant’s expense, provide and install Building
standard graphics on the door of the Premises and such portions of the Outside

               (iii)
To permit any tenant the exclusive right to conduct any business as long as such
exclusive right does not conflict with any rights expressly given to Tenant
herein; 

               (iv)
To place such signs, notices or displays as Landlord reasonably deems necessary
or advisable upon the roof, exterior of the Building or the Project or on pole
signs in the Outside Area.

               (ii)
suffer or permit anyone to go upon the roof of the Building. 

          C. Security
Regulations. 

               (i)
Security Access
Badges. One active badge, and only one, will be issued to each employee, agent,
consultant, contractor, or vendor, over the age of sixteen (16), of Tenant at
any given time. All lost or stolen badges must be reported immediately (and, in
any event, prior to 5:00 p.m., Pacific Time, on the day lost or stolen) to
Landlord to be canceled by Landlord’s Security Administrator. Tenant shall
inform Landlord immediately (and, in any event, prior to 5:00 p.m., Pacific
Time, on the day of such termination) upon Tenant’s termination of any employee
of Tenant, so that Landlord may cause such employee’s badge to be canceled by
Landlord’s Security Administrator. 

               (ii)
Security Guard Tours. Periodic, routine tours
of the space occupied by Tenant will be conducted by Landlord’s Security Guard
Contractor from 4:30 p.m. to 8:30 a.m. during normal work days and 24 hours a
day on Saturdays, Sundays and holidays observed by Landlord. The purpose of
these tours will be to observe and address abnormal conditions such as, but not
limited to: (a) unlocked exterior and interior doors, (b) extreme temperature
conditions, (c) unattended coffee pots and appliances in the ‘on’ position, and
(d) unbadged persons on the premises, 

               (iii)
Emergency Contact
List. Tenant agrees to provide a current “emergency contact list” for
Landlord’s Security Department in the event of an emergency in the space
occupied by Tenant.

-42- 

               (iv)
Miscellaneous Security. Tenant agrees to assist
Landlord in maintaining security for the entire Project. This includes but is
not limited to: (a) ensuring that all employees, consultants, contractors,
vendors, and agents are appropriately badged and/or escorted, (b) returning
badges of terminated employees to Landlord’s Security Administrator to be
deleted from the security badge system, (c) notifying Landlord’s Security Administrator immediately of lost or
missing badges, (d) ensuring that security access badges are only used by those
authorized persons to whom they are issued and that badges are not loaned to
anyone under any circumstances, and (e) instructing all Tenant’s Agents to
maintain in confidence any sensitive information overheard from any employees or
representatives of Landlord or any other tenant in the Building while in the
Outside Area. Tenant acknowledges and agrees that the security services provided
herein are not a guaranty against criminal activity and that Landlord assumes no
liability in the event of any breach of such security measures. 

               (v) Costs of
Services. All costs of services provided
by Landlord under this Paragraph 46 shall be included in Operating Expenses
under Paragraph 15.B. 

     47.
Right of First
Offer. 

     Provided that the Tenant is not in
Default, Tenant shall have the Right of First Offer on additional marketable
space (“Expansion Premises”) within the building (“Right of First Offer”) as it becomes available. Landlord shall provide Tenant with
written notice of intention to market, including the economic terms,
(“Notice of Intent to Market”). Tenant shall have twenty (20) business days from receipt
of written notice by Landlord to negotiate the economics for the Expansion
Premises. Except for the economics, all other terms and conditions for the
Expansion Premises shall be consistent with those applicable to the Premises. If
Tenant does not deliver to Landlord Tenant’s Acceptance Notice within the
applicable 20-business day period, Landlord shall have the right to market and
lease such Expansion Premises to any person(s) other than Tenant on any terms
Landlord desires and without offering or further offering such Expansion
Premises to Tenant, and Tenant shall have no further right of first offer to
lease such Expansion Premises pursuant to this Paragraph 47. Any Expansion
Premises leased by Tenant will be added to the Premises as of the date provided
in the offer, and the Rent will be adjusted to reflect the rent to be paid with
respect to Expansion Premises in accordance with the offer. Tenant agrees to
execute amendments to this Lease to reflect additions to the Premises resulting
from the exercise of the Right of First Offer. Tenant's lease of any Expansion
Premises pursuant to this Right of First Offer will be on all the terms and
conditions set forth in this Lease, with the exception of the economics, which
shall be set as described above. This Right of First Offer to lease the
Expansion Premises is personal to Tenant or any Permitted Transferee, and is not
transferable. Notwithstanding the foregoing,
Tenant shall not have the Right of First Offer under this Paragraph 47 if Tenant
is in Default under this Lease at the time such Expansion Premises becomes
available (and Landlord shall have no obligation to deliver to Tenant any
Landlord’s Notice). In addition to the Right of First Offer, Tenant shall have
the option to expand into contiguous space or relocate to another suite if space
becomes available. Terms will be negotiated at the time of such expansion or
relocation. 

-43- 

     48. Ownership of
Furniture and Fixtures.

     All furniture, cubicles, telephones
and other items supplied to Tenant by Landlord during the term of this Lease
shall remain the property of the Landlord at the end of the Lease and shall be
returned in good condition, normal wear and tear excepted. 

     Certain furniture in that portion of
the Premises currently occupied by Tenant under the 2007 Lease (the “Existing
Space”) is owned by Landlord. For the duration of Tenant’s occupancy in the
Premises, Tenant shall have the right to continue to utilize furniture owned by
Landlord in the Existing Space at no additional cost.

     If surplus furniture is available
and left in that portion of the Premises other than the Existing Space, Landlord
will make such furniture available to Tenant at no additional cost during the
Term of the Lease. Said furniture shall remain the property of the Landlord.
Within sixty (60) days after the Commencement Date, Tenant will notify Landlord
in writing of any furniture, fixtures or equipment in the Premises that it does
not wish to use, and Landlord will be responsible for promptly removing such
furniture, fixtures and equipment, at
Landlord’s expense. If Tenant elects to do so, a furniture inventory and
condition report will be written and signed by Tenant and Landlord promptly
after the Commencement Date.

     49. General.

          A. Captions. The captions and headings used in this Lease are for the
purpose of convenience only and shall not be construed to limit or extend the
meaning of any part of this Lease. 

          B. Executed
Copy. Any fully executed copy of this Lease shall be deemed an original for all
purposes. 

          C. Time. Time is of the
essence for the performance and observance of each term, covenant and condition
of this Lease. 

          D. Severability. If one or more of the provisions contained herein, except for
the payment of Rent, is for any reason held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality, or unenforceability
shall not affect any other provision of this Lease, but this Lease shall be
construed as if such invalid, illegal or unenforceable provision had not been
contained herein. 

          E. Choice of
Law. This Lease shall be construed and enforced in accordance with the laws of
the State of California. The language in all parts of this Lease shall in all
cases be construed as a whole according to its fair meaning and not strictly for
or against either Landlord or Tenant. 

          F. Interpretation. When the context of this Lease requires, the neuter gender
includes the masculine, the feminine, a partnership or corporation or joint
venture, and the singular includes the plural. The term “including” shall be
deemed to mean “including, but not by way of limitation” and the term “or” has
the inclusive meaning represented by the term “and/or.”

-44- 

          G.
No Effect of
Remeasurement. The statements of rentable
square footage set forth in this Lease are for the convenience of the parties,
and no adjustment shall be made to rental amounts, load factors or Tenant’s
Building Percentage if such square footage is later shown to be inaccurate.

          H. Binding
Effect. The covenants and agreement contained in this Lease shall be binding on
the parties hereto and on their respective successors and assigns to the extent
this Lease is assignable. 

          I. Waiver. The waiver by either
party of any breach of any term, covenant or condition of this Lease shall not
be deemed to be a waiver of such provision or any subsequent breach of the same
or any other term, covenant or condition of this Lease. The acceptance of Rent
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
at the time of acceptance of such payment. No term, covenant or condition of
this Lease shall be deemed to have been waived by either party unless the waiver
is in writing signed by the non-breaching party, as applicable. 

          J. Entire
Agreement. This Lease, including the Information Sheet, is the entire agreement
between the parties, and there are no agreements or representations between the
parties except as expressed herein. Except as otherwise provided herein, no
subsequent change or addition to this Lease shall be binding unless in writing
and signed by the parties hereto. 

          K. Authority. If Tenant is an
entity, each individual executing this Lease on behalf of such entity,
represents and warrants that he or she is duly authorized to execute and deliver
this Lease on behalf of the entity in accordance with its governing documents,
and that this Lease is binding upon the entity in accordance with its terms.
Landlord, at its option, may require a copy of such written authorization to
enter this Lease. The failure of Tenant to deliver the same to Landlord within
fifteen (15) days of Landlord’s request therefor shall be deemed a Default under
this Lease. 

          L. Exhibits. All exhibits,
amendments, riders and addenda attached hereto are hereby incorporated herein
and made a part hereof. 

          M. Counterparts. This Lease may
be executed in counterparts, each of which shall be an original, but all
counterparts shall constitute one (1) instrument. 

          N. Force
Majeure. Neither party shall be held
liable to the other party nor be deemed to have defaulted under or breached this
Lease for failure or delay in 

          O. performing
any obligation under this Lease to the extent that such failure or delay is
caused by or results from causes beyond the reasonable control of the affected
party, potentially including, but not limited to, embargoes, war, acts of war
(whether war be declared or not), insurrections, riots, civil commotions,
strikes, lockouts or other labor disturbances, fire, floods, or other acts of
God, or acts, omissions or delays in acting by any governmental authority or the
other party. The affected Party shall notify the other party of such force
majeure circumstances as soon as reasonably practical, and shall promptly
undertake all reasonable efforts necessary to cure such force majeure
circumstances.
