FOUNDATION HEALTH, A CALIFORNIA HEALTH PLAN,

a California corporation
(Tenant)

Aerojet 2025 Building, Rancho Cordova, California

THIS SECOND ADDENDUM is attached to and made part of the above-referenced lease, which lease includes an Addendum to Lease that contains Sections 35
through 49 (collectively, the Lease). Unless otherwise defined in this Second Addendum, all capitalized terms used in this Second Addendum shall have the same meaning as such capitalized terms have in the Lease. All references within
this Second Addendum to a Section are to a specific section within the Lease unless otherwise indicated,

1. Sections 4 and
37, Possession. If Landlord, for any reason other than a Tenant-caused delay, shall fail to substantially complete Landlords Work and deliver the Premises to Tenant by September 1, 1995 (the Scheduled Commencement Date),
the parties agree that Tenant shall have the following remedies:

(a) If such delivery occurs later than thirty (30) days after the
Scheduled Commencement Date, then Tenant shall be entitled to one (1) day of free rent for each day after said thirty (30) days that Landlord is late in so delivering the Premises.

(b) If such delivery occurs later than ninety (90) days after the Scheduled Commencement Date, then Tenant may terminate the Lease by written
notice to Landlord prior to Tenants occupancy of the Premises.

2. Section 5, Rent. The parties acknowledge that Tenant
shall have no obligation to pay operating expenses, other than the cost of electrical and gas service pursuant to Section 45.

3. Section 9, Compliance with Law. Tenants obligation under Section 9 of the Lease and elsewhere in the Lease with respect to the compliance with laws, statutes, ordinances, and governmental rules and regulations
(including, but not limited to, the Americans with Disabilities Act of 1990), as all of the same may be amended and supplemented from time to time (collectively, Laws) shall be limited to (i) Laws pertaining to Tenants
personal property; (ii) Laws pertaining to modifications made to the Premises by Tenant; and (iii) Laws pertaining to Tenants specific use of the Premises. Landlord, at Landlords sole cost and expense, shall comply with all
other Laws pertaining to the Building and parking area; provided, however, that if the aggregate cost of the Landlords complying with any Laws exceeds Two Hundred Fifty Thousand Dollars ($250,000.00), and Landlord did not have actual or
constructive notice prior to commencement of the term of the general cost of the compliance now being required, and Tenant is unwilling to pay the cost of such compliance in excess of $250,000.00 (it being agreed that Tenant has no obligation to pay
such cost), Landlord shall have the right to terminate the Lease upon one hundred twenty (120) days written notice to Tenant. If Landlord

exercises such termination right, Landlord shall pay reasonable costs and expenses incurred by Tenant in relocating to new premises, not to exceed
Seventy-Five Thousand Dollars ($75,000.00).

4. Section 10, Alterations and Additions.

(a) Landlords consent to alterations, additions or improvements (collectively, Alterations) shall in no event be unreasonably withheld
or delayed.

(b) In no event shall Tenant be obligated to remove any Alterations on the Premises (including, but not limited to, the
leasehold improvements constructed by Landlord), unless such Alterations were made by Tenant during the term of the Lease. If Tenant desires to have the right to surrender the Alterations at the expiration of the Lease term and not remove them from
the Premises, Tenant shall, at the time that it requests Landlords consent to the making of those Alterations, notify Landlord of such desire, and Landlord shall have the option to either (i) require such surrender of the Alterations, or
(ii) expressly condition Landlords approval of such Alterations on Tenants agreement to remove such Alterations at the expiration of the Lease term,

5. Sections 11, Repairs. Tenant shall not be responsible for the correction or repair of any latent defect in the Premises, or any existing defect or code violation in existence prior to the commencement of the
term. The repairs or maintenance that are Landlords responsibility shall be done diligently and on a timely basis.

6.
Section 17, Services and Utilities. If any utility or other service to the Premises is interrupted, Tenant shall be entitled to an abatement of rent (proportionate to the degree to which Tenants use of the Premises for office
purposes is interfered with) until ouch interruption is cured by Landlord. Landlord shall use diligent and good faith efforts to promptly restore utility service.

7. Section 21, Entry by Landlord. Landlord shall provide to Tenant advance notice of Landlords entry onto Premises (except in the case of an emergency, or in such cases as Landlords security
procedures do not reasonably permit advance notice). Landlords right to enter the Premises to show them to prospective tenants pursuant to Section 21 shall be limited to the last six (6) months of the Lease term. In no event shall
Landlords access onto the Premises unreasonably interfere with Tenants use of the Premises.

8. Section 22,
Reconstruction. Tenant shall be entitled to a rent abatement pursuant to Section 22, from the date of the casualty until the repairs are completed, whether or not such casualty is covered by Landlords insurance.

9. Section 23, Default. In Section 2.3.a, the words vacating or are hereby deleted. In Section 23.b, the words
three (3) days are hereby replaced with ten (10) days.

10. Section 29(ii), Waiver. This
waiver by Tenant of any term, covenant or condition in the Lease or this Second Addendum shall not be deemed a waiver of such term, covenant or condition or any subsequent breach of the same or any other term, covenant or condition contained in the
Lease or this Second Addendum.

applicable laws. Tenants responsibility respecting hazardous materials or hazardous substances shall be limited to those materials actually introduced by Tenant in the Premises; the responsibility for compliance with laws respecting all other
hazardous materials or hazardous substances shall be Landlords.

13. Section 36A, Landlords Obligations. Landlord
and Tenant shall, as soon as possible after the execution of the Lease, and from time to time during the course of construction, confer respecting the Landlords Work, such that Tenant will be kept apprised of the progress of that work, and so

NOW, THEREFORE, Landlord and
Tenant, in consideration of the foregoing recitals and the covenants contained in this Fifth Addendum, agree as follows:



|1. | Expansion of the Premises. Landlord does hereby lease to Tenant, and Tenant hereby leases from Landlord, approximately thirty thousand (30,000) rentable square feet of

| | Index, unadjusted, for All Urban Consumers (all items), as published by the United States Department of Labor, Bureau of Labor Statistics, for the San
Francisco-Oakland-San Jose Area (1982-84 = 100 Base) (the CPI), has increased from the CPI as published for September, 1997 to the CPI as published for September, 1998; and (2) on October 1, 1999, the rent for the Existing

| | C. | Another Index. If the CPI is not in existence at the time any increase is to be computed, Landlord and Tenant shall utilize such other index published by that governmental
authority as shall be most similar thereto and consistent with the intent to adjust the rent in accordance with changes, if any, in the cost-of-living that occurs during the applicable period.

Addendum (the Superseded Extension Periods), nor shall Landlord have any duty to pay the brokers fee that would have been payable in connection with the Superseded Extension Periods under Section 46 of the Addendum to Lease.

increase by the same percentage as the CPI has increased from March, 2001 to March, 2002; provided that under no circumstances shall either of said increases in rent, the one occurring April 1, 2001 and the other occurring on April 1,
2002, exceed three and one-quarter percent.(3.25%). Landlord shall calculate and notify Tenant of all applicable rental increases. If the CPI for

Permanent Improvements) to the premises, including, but not limited to, costs associated with architectural designs engineering, preparation of plans and specifications, permits and fees, labor and materials, equipment purchase or
rental amounts paid to contractors, including contractor profit and overhead, provided that all such Permanent Improvements shall be constructed in accordance with plans and specifications that are mutually approved by Landlord and Tenant. Landlord
agrees to commence installation of the Permanent Improvements as promptly as may be reasonably possible after said plans and specifications are mutually approved and all necessary permits are obtained, to make reasonable efforts to minimize any
disruption to Tenants business operations as a result of such installation, and to prosecute such installation to completion with commercially reasonable diligence. Materials used for said Permanent Improvements shall be of the same or similar
quality as those materials previously used by Landlord in the repair and improvement of the Premises pursuant to the Lease. The contract between Landlord and its general contractor construction of the Permanent Improvements shall be a fixed-price
contract for all of the work contemplated, and Landlord shall give Tenant a copy thereof at least five (5) business days before it is fully executed and delivered by Landlord and its general contractor. Tenant acknowledges that the amount of

Renovation Allowance, then Tenant shall, upon presentation of invoices or other reasonable proof of the cost thereof, pay, or reimburse Landlord for, such excess.

| | C. | Consultants and Contractor. Although Landlord will pay, out of the Renovation Allowance, the costs of design work for the Permanent Improvements, Tenant shall have the right
to select an interior space planning firm and other consultants to prepare said plans and specifications for Landlord and Tenant mutually to approve, except that Landlord, and not Tenant, shall select the engineer or engineering company to be used.
Landlord and Tenant agree to engage REF & Sons as the general contractor to construct the Permanent Improvements (Tenant acknowledges that Landlord has advised Tenant that Landlord will not accept an alternative contractor) in accordance
with the mutually approved plans and specifications. Landlord and Tenant agree to engage Forrar Williams & Associates as the architectural firm to do the interior space planning and design work and to prepare the plans and specifications
for the Permanent Improvements (Landlord acknowledges that Tenant has advised Landlord that Tenant will not accept an alternative design, planning, and architectural firm).

| | F. | The Reimbursement Option. Notwithstanding that subparts B through D of this paragraph 4 contemplate that Landlord shall arrange for, and supervise, the renovation and
improvement work for which the Renovation Allowance or some portion thereof is to be spent after the Additional Term has commenced, Landlord agrees that, at any time prior at any time or to commencement of the Additional Term Tenant may give
Landlord written notice of Tenants desire to have that work done before commencement of the Additional Term (an Early Work Notice). If and when an Early Work Notice is given, then Tenant may itself arrange for, and

Amount), which Reimbursement Amount shall not exceed the amount of the Renovation Allowance; and

amortize, during the five (5) years of the Additional Term, in equal monthly installments, the Expended Allowance or the Reimbursement Amount, as the case may be, plus interest accruing on the unpaid balance thereof at ten percent
(10%) per annum provided that, if no part of the Renovation Allowance is actually expended by Landlord, then such Additional Rent shall not become due. For example, if Landlord expends all of the Renovation Allowance then the Additional Rent
will be Twenty-One Thousand Four Hundred Twenty Five Dollars and Ninety-Four Cents ($21 425.94) payable in advance on the first (1st) day of
each month, commencing on the first (1st) day of the Additional Tern, notwithstanding that the Renovation Allowance is expended after

contained within the Deleted Area (although the exact number of rentable square feet shall be determined by Landlord by application of the method for determining rentable area under the ANSI/BOMA Z65.1-1996 standard) and a commitment by
Tenant to surrender to Landlord, on the Contraction Date, possession of the Deleted Area;

such Expansion Area determined as set forth in subpart E of this paragraph 6); provided that, if through no fault of Landlord, Tenant and Landlord have not, within ninety (90) days after the Expansion Notice is given, entered into a fully
executed addendum to the Lease, then Landlord may, by written notice to Tenant, terminate Tenants Expansion Option, and upon the giving of such written notice, Tenant shall have no further interest in, or rights to, the Expansion Area;

provisions of the Lease that will remain constant, including, but not limited to, the term thereof as hereby modified, the improvements installed by Landlord, services provided to Tenant, the fact that said fair market rental for the Expansion Area
shall not be subject to increase during the Additional Term, and other pertinent items and the amenities, location, identity, quality, age, and conditions of the buildings in which the Premises are located; provided that, in no event shall the
monthly rental per rentable square foot for the Expansion Area be less than the monthly rental per rentable square foot payable for the Premises under paragraph 2 hereof, as of the date the Expansion Notice is given, regardless what the fair market
rental for the Expansion Area may be. The fair market rental for the Expansion Area shall be determined by applying the following procedures and subject to the following terms and conditions:

Expansion Area;

| | iv. | If both Landlord and Tenant give Expansion Area Fair Rental Notices, and the Expansion Fair Rental Notices are different in any respect, then the fair market rental for the
Expansion Area shall be conclusively established by a third-party appraiser mutually chosen by Landlord and Tenant; provided that, if Landlord and Tenant have not agreed upon, and engaged, such appraiser within sixty (60) days after the
Expansion Notice was given, then Landlord and Tenant shall each engage a duly licensed California attorney with commercial leasing experience of at least five (5) years, which attorneys shall, by their agreement, select the appraiser; provided
that, if said attorneys have not agreed upon an appraiser within seventy-five (75) days after the Expansion Notice was given, then the appraiser shall be selected by the Presiding Judge of the Superior Court of Sacramento County acting in his
or her individual capacity if said Judge is willing to do so;

Rental Notice; the appraiser shall not be permitted to decide on a middle ground, or to suggest any compromise; the appraisers sole function shall be to determine the Chosen Expansion Area Fair Rental Notice, and provide his or her reasons
therefor.

Notice) setting forth a description of the available space (the Available Space) the monthly rental rate, and all other material terms and conditions upon which Landlord intends to offer the Available Space. A
Landlords Notice shall be deemed to be an offer to lease to Tenant the Available Space on the terms stated therein;

| | B. | Upon Tenants receipt of a Landlords Notice, Tenant shall have five (5) business days to respond by giving Landlord a written acceptance setting for Tenants
commitment to lease the Available Space on the terms stated in the Landlords Notice (a Tenants Acceptance);
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | If Tenant fails to give to Landlord a Tenants Acceptance within said five (5) business days, that failure shall be deemed to be a rejection of Landlords offer to
lease the Available Space (a Tenants Rejection) and, except as provided in subpart E of this paragraph 7 shall be deemed a termination of Tenants First Right, so that Landlord shall have no further duty to give any
Landlords Notice respecting the Available Space or any other space it may own from time to time, just as if this paragraph 7 were not a part of this Eighth Addendum;
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | D. | After any Tenants Rejection, Landlord shall, for a period of one (1) year, be free to lease the Available Space to any other person or entity for rent and upon the terms
and conditions at least as favorable to Landlord as those set forth in the Landlords Notice;
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | E. | If (a) during said one (1) year Landlord desires to lease the Available Space upon terms and conditions that are less favorable to Landlord than those set forth in the
Landlords Notice, or (b) the Available Space is not leased by Landlord to another person or entity within said one (1) year, and if Landlord desires to continue to seek a tenant therefor, then, and in either of those events, Landlord
must give Tenant another Landlords Notice respecting that Available Space, and the provisions of this paragraph 7 shall again apply;

| | F. | If and when Landlord has without breach of this paragraph 7, leased any space that is subject to the First Right to another person or entity, the First Right shall terminate and be
of no further force or effect, this paragraph 7 being then deemed not to be a part of this Eighth Addendum; and
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | G. | If a Tenants Rejection ever occurs, Tenant agrees to provide to Landlord such written proof, including, but not limited to, an estoppel certificate, as Landlord may request to
prove when Landlord leases or is negotiating to lease, or seeking a tenant for, the Available Space, that the First Right no longer applies thereto, which written proof shall be provided within five (5) business days after Landlords
written request therefor is received by Tenant.

| | B. | If the Lease is terminated prior to the end of the Payment Period by reason of fire or other casualty, condemnation or any other event beyond the reasonable control of Tenant (and
in all events excluding a termination resulting from Tenants default or breach of the Lease), Landlord agrees, within thirty (30) business days after such termination, to pay Tenant the unearned balance of the Monthly Rent, calculated at
the rate of Six Thousand Four Hundred Thirty Nine and 27/100ths Dollars ($6,439.27) per day (the Per Diem Amount).
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | If, during the Payment Period, an event occurs that would entitle Tenant to an abatement or reduction of monthly rent payable under the Lease (including, but not limited to Sections
22 and 25 of the Original Lease, and Sections 6 and 8 of the Second Addendum, such abatement or reduction (on a daily rate equal to the Per Diem Amount) shall be credited to Tenants monthly rent obligations that accrue following the Payment

may be payable under Section 4.H of the Eighth Addendum, and nothing in this Ninth Addendum is intended to modify Tenants obligation to pay Additional Rent pursuant to Section 4.H of the Eighth Addendum). The parties agree that the
payment of the Additional Rent shall satisfy in full any obligation Tenant has under the Lease to pay (i) previous CPI increases in monthly rent (including, but not limited to any increases referenced in Sections 3 and 4 of the Fifth Addendum,
and Sections 2 and 4 of the Sixth Addendum), and (ii) any CPI increase in monthly rent scheduled to occur on April 1, 2002 pursuant to clause (b) of Section 4.C of the Fifth Addendum, notwithstanding any contrary provision of the
Lease. The parties acknowledge and agree that the Additional Rent amount represents a negotiated amount, and it is intended that the payment of such Additional Rent shall fully and finally settle any dispute or potential dispute arising from
previous CPI increases in monthly rent.

|3. | Mortgages. Landlord hereby represents and warrants to Tenant that the Premises are not currently encumbered by any mortgage or deed of trust, and therefore, no lenders
non-disturbance and attornment agreement is necessary or appropriate.
|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

AGREEMENT

NOW, THEREFORE, Landlord

| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Term. Landlord and Tenant agree that the term of the Lease for the Building 2019 Expansion Space shall commence, subject to any Phased TI Completion (defined below), on the
date as of which Landlord has substantially completed the TI Work (defined below) (the Completion Date), and shall expire on July 31, 2009 (the New Expiration Date). Landlord hereby grants to Tenant an
option to extend the term of the Lease for the Existing Premises (the Existing Premises Option) from its current expiration date of September 30, 2007 (the Old Expiration Date), to the New Expiration Date
(the New Additional Term); provided that, unless, prior to March 31, 2007, Tenant gives to Landlord a written notice that Tenant does not exercise the Existing Premises Option, Tenant shall be deemed to have exercised the
Existing Premises Option as of Old Expiration Date. Thus, unless such a notice of non-exercise of the Existing Premises Option is timely given, the term of the Lease for both the Building 2019 Expansion Space and the Existing Premises shall expire
on the same day. Notwithstanding the foregoing provisions of this paragraph 2, (a) Landlord and Tenant agree to work together and cooperate in connection with the TI Work such that substantial completion of the TI Work, and delivery by Landlord
to Tenant of the completed Building 2019 Expansion Space, may be accomplished in phases (collectively, Phased TI Completion); and (b) if Phased TI Completion does occur, the term of the Lease for the Building 2019 Expansion
Space, and the payment of monthly rent, as set forth in paragraph 3 of this Tenth Addendum, shall both commence as of the delivery or deliveries of possession for each such phase or phases of the Phased TI Completion (each, a Phased
Completion Date);provided that no such Phased Completion Date shall accelerate the New Expiration Date for that phase, but shall increase the length of the term of the Lease applicable thereto by the number of days said Phased
Completion Date precedes the Completion Date. The provisions of this paragraph 2 and the provisions of paragraph 6 of this Tenth Addendum supersede and replace entirely any and all extension, contraction, and expansion options Tenant may have had
under the Lease as it existed prior to this Tenth Addendum, including, but not limited to, paragraphs 3, 5, and 6 of the Eighth Addendum. When the Completion Date or any Phased Completion Date occurs, Landlord and Tenant shall then promptly execute
and deliver to each other, based upon the form attached hereto as Exhibit Cand incorporated herein by this reference, a written certification (an Building 2019 Expansion Space Completion Date Certification) of
the Completion Date or Phased Completion Date, as the case may be, and, if requested by Landlord or Tenant, a further addendum to the Lease setting forth the Completion Date or Phased Completion Date and the monthly rental amount applicable thereto.
As of the execution of this Tenth Addendum, Landlord estimates that a Phased TI Completion may be accomplished on the schedule set forth in Exhibits D-1 and D-2attached hereto and incorporated herein by this
reference.

|3. | Rent. The monthly rent for the Existing Premises for the period prior to, and including, the Old Expiration Date is not modified by this Tenth Addendum, but continues on the
same schedule as set forth in paragraphs 2 and 4H of the Eighth Addendum. If the Existing Premises Option is deemed exercised as set forth in paragraph 2 of this Tenth Addendum, then the monthly rent for the Existing Premises for the New Additional
Term, being the period commencing immediately after the Old Expiration Date and ending on the New Expiration Date, shall be at the same rates per rentable square foot as apply, from time to time, to the Building 2019 Expansion Space as set forth in
the next sentence of this paragraph 3. The monthly rent for the term of this Lease applicable to the Building 2019 Expansion Space, commencing on the Completion Date (subject to earlier commencement of monthly rent if and when any Phased Completion
Date occurs) and expiring on the New Expiration Date, shall be calculated by multiplying the number of rentable square feet thereof by the following amounts: (a) One Dollar and Thirty-Eight Cents ($1.38) for the period commencing on the
Completion Date and ending July 31, 2005; (b) One Dollar and Forty Cents ($1.40) for the period commencing August 1, 2005, and ending July 31, 2006; (c) One Dollar and Forty-Two Cents ($1.42) for the period commencing
August 1, 2006, and ending July 31, 2007; (d) One Dollar and Forty-Four Cents ($1.44) for the period commencing August 1, 2007, and ending July 31, 2008; and (e) One Dollar and Forty-Six Cents ($1.46) for the period
commencing August 1, 2008, and ending July 31, 2009. If a Phased TI Completion occurs, then the monthly rent for the period or periods, commencing upon each Phased Completion Date, and expiring on the Completion Date, shall be calculated
by multiplying the number of rentable square feet in the completed phase by One Dollar and Thirty-Eight Cents ($1.38). Such rent shall be set forth in the Building 2019 Expansion Space Completion Date Certification applicable to that phase.
Notwithstanding the foregoing provisions of this paragraph 3, Tenant agrees to pay to Landlord, in advance, in two (2) equal installments as set forth below, to be credited to the monthly rent for the Building 2019 Expansion Space for the
thirteen (13) month period commencing on December 1, 2004, and expiring on December 31, 2005, Nine Hundred Seventy-Two Thousand Nine Hundred Dollars ($972,900.00) (the Prepaid Rent), and upon Tenants timely
payment of the Prepaid Rent, the rental rate per rentable square foot for the Building 2019 Expansion Space and for the Existing Premises, for the period commencing on December 1, 2005, and expiring on New Expiration Date, shall be reduced by
Two Cents ($.02) from the scheduled amounts set forth above in this paragraph 3; provided that, if the Existing Premises Option is not deemed exercised as set forth in paragraph 2 of this Tenth Addendum, then said reduction in the rental rate for
the Existing Premises will expire on the Old Expiration Date. One-half (1/2) of the Prepaid Rent, being the amount of Four Hundred Eighty-six Thousand Four Hundred Fifty Dollars ($486,450.00), shall be paid within fifteen (15) days after
the execution of this Tenth Addendum; the other one-half (1/2) of the Prepaid rent, being the amount of Four Hundred Eighty-six Thousand Four Hundred Fifty Dollars ($486,450.00), shall be paid upon the Completion Date.

in the Chosen Fair Rental Notice shall be deemed to be the fair market rental; and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | vii. | The appraiser or broker shall be required to give to Landlord and to Tenant a written statement of the appraiser or brokers reasoning and justification for selection of the
Chosen Fair Rental Notice; the appraiser or broker shall not be permitted to decide on a middle ground, or to suggest any compromise; the appraiser or brokers sole function shall be to determine the Chosen Fair Rental Notice, and provide his

| | A. | Improvement Allowance. Landlord shall make available for paying costs of improving the Building 2019 Expansion Space an allowance of Twenty-Five Dollars ($25.00) per rentable
square foot of the Building 2019 Expansion Space (the TI Allowance). Landlord shall, at Landlords sole cost and expense, and without charge against the TI Allowance, cause the Building 2019 Expansion Space to be a
standard building shell (as more specifically described in Exhibit Eattached hereto and incorporated herein by this reference) that complies with all applicable building codes and regulations (the Standard
Building Shell) and to which Landlord may lawfully add the TI Work (defined below). Within thirty (30) days following the Completion Date, Landlord shall send to Tenant a written notice setting forth the amount of the Expended
Allowance (defined below). If the Expended Allowance is less then the amount of the TI Allowance, then Landlord shall apply the difference solely to the reasonable cost of such additional permanent improvements to the Building 2019 Expansion Space
as are reasonably requested by Tenant and approved by Landlord. For construction of such additional permanent improvements, Tenant shall, or, at Landlords option, Landlord shall, engage REF & Sons, being the contractor authorized by
Landlord to work in the Building 2019 Expansion Space.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

to, costs associated with architectural design, engineering, preparation of plans and specifications, permits and fees, labor and materials, equipment purchase or rental, amounts paid to contractors, including contractor profit and overhead,
provided that all such TI Work shall be done in accordance with plans and specifications that are mutually approved by Landlord and Tenant. Landlord agrees to commence installation of the TI Work as promptly as may be reasonably possible after said
plans and specifications are mutually approved and all necessary permits are obtained, to make reasonable efforts to minimize any disruption to Tenants business operations as a result of such installation, and to prosecute such installation to
completion with commercially reasonable diligence. Materials used for said TI Work shall be of the same or similar quality as those materials previously used by Landlord in the repair and improvement of the Premises pursuant to the Lease; provided
that Tenant may elect to use better quality materials as part of the plans approval process. The work order or contract between Landlord and its general contractor for construction of the TI Work shall be a fixed-price work order or contract for all
of the work contemplated and shall be reasonably priced, and Landlord shall give Tenant a copy thereof at least five (5) business days before it is fully executed and delivered by Landlord and its general contractor. Tenant acknowledges that
the amount of such contract will not include the cost of any change orders or corrections issued by the architect or Tenant. If the cost of any such change orders or corrections causes the total cost for the TI Work to exceed

for, such excess: provided that, if a change order is issued by Tenant, then, before Landlord implements said change order, Landlord shall obtain Tenants approval of the estimated cost of implementing that change order; provided further that,
if a correction is required due to a defect in the original construction of the building or to complete the Standard Building Shell, then such correction shall be made at Landlords sole cost and expense, and the cost thereof shall not be
charged against the TI Allowance.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | Consultants and Contractor. Although Landlord will pay, out of the TI Allowance, the costs of design work for the TI Work, Tenant shall have the right to select an interior
space planning firm and other consultants to prepare said plans and specifications for Landlord and Tenant mutually to approve (Tenants selection of an architectural firm is set forth below in this paragraph), except that Landlord, and not
Tenant, shall select the engineer or engineering company to be used; provided such engineer or engineering company provides services at commercially reasonable rates. Landlord and Tenant agree to engage REF & Sons as the general contractor
to do the TI Work (Tenant acknowledges that Landlord has advised Tenant that Landlord will not accept an alternative contractor) in accordance with the mutually approved plans and specifications. Landlord and Tenant agree to engage Architectural
Arts as the architectural firm to do the interior space planning and design work and to prepare the plans and specifications for the TI Work (Landlord acknowledges that Tenant has advised Landlord that Tenant will not accept an alternative design,
planning, and architectural firm).

| | D. | Organized Labor. Landlord and its general contractor shall provide organized labor (construction trades) the opportunity to participate in the construction of the TI Work via
the bidding process. When applicable, Landlord shall award any job or jobs to companies using organized labor if they are the most responsive and their pricing is competitive.

AGREEMENT

NOW, THEREFORE, Landlord and Tenant, in consideration of the foregoing recitals, all of which are incorporated herein by this reference, and the
covenants contained in this Twelfth Addendum, agree as follows:



|1. | The New Extension Option. Section 4 of the Tenth Addendum is hereby deleted from the Lease and replaced entirely by the following new Section 4:
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------



|2. | Extension of Term.
|-- | ------------------



| | A. | New Extension Option. Tenant shall have the right and option (the New Extension Option) to extend the term of the Lease for five (5) years beyond
July 31, 2009 (the New Expiration Date), to expire instead on July 31, 2014 (the New Extension Period); provided that:
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | i. | Tenant must give to Landlord, and Landlord must have received, by mail or by personal delivery, written notice of Tenants election to exercise the New Extension Option no
later than one hundred twenty (120) days prior to the New Expiration Date;
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



A12 - 2



---

| | ii. | At the time Tenant gives said written notice to Landlord, and at the time the New Extension Period commences, Tenant must not, after the giving of written notice and the passage of
the applicable cure period, if any, be in default under the Lease;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii. | Tenant may exercise the New Extension Option with respect to all of the Premises only, and may not exercise the New Extension Option with respect to only part of the Premises; and
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iv. | Failure by Tenant to provide timely or adequate written notice as set forth herein shall, unless, and in the sole discretion of Landlord, an untimely or inadequate notice is
acceptable to Landlord, cause the New Extension Option to lapse and its exercise by Tenant shall not be effective.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | Tenants Termination Right. If and when the New Extension Period commences, Tenant shall thereafter have the right and option to terminate the Lease
(Tenants Termination Option) effective as of July 31, 2011, July 31, 2012, or July 31, 2013 (each, a Termination Date); provided that Tenants Termination Option may be exercised
only by giving to Landlord a written notice of termination no later than ninety (90) days before the Termination Date chosen by Tenant. Any such termination of the Lease shall apply to all of the Premises, and cannot be applied to only a
portion or portions of the Premises
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | C. | Rent during the New Extension Period. The monthly rental payable during the New Extension Period shall be the fair market rental for the Premises, as of the beginning of the
New Extension Period, taking into account the specific provisions of the Lease that will remain constant, including, but not limited to, the term thereof as hereby modified, the improvements installed by Landlord, services provided to Tenant, the
fact that said monthly rental based upon the fair market rental shall not be subject to increase during the New Extension Period, the cost to Landlord of paying any brokerage commission in connection with Tenants exercise of the New Extension
Option, and other pertinent items, and the amenities, location, identity, quality, age, and conditions of the buildings in which the Premises are located; provided that, in no event, shall the monthly rental payable for the Premises during the New
Extension Period be less than the monthly rental payable for the month immediately preceding the New Expiration Date, regardless what the fair market rental may be. The fair market rental for the Premises shall be determined by applying the
following procedures and subject to the following terms and conditions:
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | i. | At least one hundred (100) days prior to the New Expiration Date, Landlord and Tenant may meet and confer, but are not obligated to meet and confer, respecting the
establishment of the fair market rental;
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ii. | In the event that Landlord and Tenant fail to meet and confer or cannot agree upon the fair market rental at least ninety (90) days prior to the New Expiration
Date, then, at least eighty (80) days prior to the New Expiration
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



A12 - 3



---

| | Date (the Notice Deadline), Landlord and Tenant shall each give to the other a written notice setting forth its final determination of the
fair market rental (collectively, the Fair Rental Notices); provided that, in order to help prevent inadvertent loss of any partys right to give a Fair Rental Notice, the Notice Deadline shall extend, for both Landlord and
Tenant, until one (1) of them gives a Fair Rental Notice plus, for the other, a period expiring five (5) business days thereafter.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | iii. | If only one (1) Fair Rental Notice is timely given, then that Fair Rental Notice shall conclusively establish the fair market rental;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------



| | iv. | If both Landlord and Tenant give Fair Rental Notices, and the Fair Rental Notices are different in any respect, then the fair market rental shall be conclusively established by a
third-party appraiser or broker mutually chosen by Landlord and Tenant; provided that, if Landlord and Tenant have not agreed upon, and engaged, such appraiser or broker at least sixty (60) days prior to the New Expiration Date, then Landlord
and Tenant shall each engage a duly licensed California attorney with commercial leasing experience of at least five (5) years, which attorneys shall, by their agreement, select the appraiser or broker; provided that, if said attorneys have not
agreed upon an appraiser or broker at least fifty (50) days prior to the New Expiration Date, then either Landlord or Tenant may commence an action for declaratory relief or other appropriate remedy to have the court appoint the appraiser or
broker;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | v. | Landlord and Tenant shall share equally the fees and expenses of the selected appraiser or broker and shall each pay its own attorneys fees;
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------



| | vi. | Within thirty (30) days after the appraiser or brokers engagement, the appraiser or broker shall deliver to Landlord and to Tenant the appraiser or brokers
determination of which of the two (2) Fair Rental Notices is, in the appraiser or brokers best judgment, the closest to the fair market rental for the Premises (the Chosen Fair Rental Notice), and the amount set forth
in the Chosen Fair Rental Notice shall be deemed to be the fair market rental; and
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | vii. | The appraiser or broker shall be required to give to Landlord and to Tenant a written statement of the appraiser or brokers reasoning and justification for selection of the
Chosen Fair Rental Notice; the appraiser or broker shall not be permitted to decide on a middle ground, or to suggest any compromise; the appraiser or brokers sole function shall be to determine the Chosen Fair Rental Notice, and provide his
or her reasons therefor.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3. | Brokerage Commissions. Landlord makes no commitment to pay a brokerage commission to CBRE in connection with this Twelfth Addendum or any exercise of the New
Extension Option unless and until, and only to the extent that, Landlord and CBRE
|-- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



A12 - 4



---

| | enter into a separate commission agreement (a CBRE Commission Agreement). In no event shall any brokerage commission paid by Landlord to
CBRE, for the New Extension Period, exceed the brokerage commission that Landlord would owe to C&W under the terms of Section 12B(d) of said Tenth Addendum; provided further that any such brokerage commission, if paid, shall be paid only as
and when Tenant exercises the New Extension Option, triggering a brokerage commission based upon two (2) years of rent, and Tenant elects not to exercise Tenants Termination Option as of each Termination Date, each such event triggering a
brokerage commission based upon one (1) year of rent. In no event shall Landlord pay brokerage commissions to both C&W and CBRE whether or not a CBRE Commission Agreement is executed. Landlord shall have the right, in its absolute
discretion, in all events, to decline to pay any brokerage commission to CBRE unless and until Tenant and CBRE provide to Landlord satisfactory assurances and indemnity, including indemnity against attorneys fees incurred, against any possible
Landlord liability to C&W under either Section 12B(d) of the Tenth Addendum or the C&W Commission Agreement.

|4. | Effect. Landlord and Tenant agree that the Lease is in full force and effect without modification except as expressly set forth in this Twelfth Addendum.
|-- | ---------------------------------------------------------------------------------------------------------------------------------------------------------



|5. | Estoppels. Landlord and Tenant acknowledge and agree that, as of the execution and delivery of this Twelfth Addendum, neither Landlord nor Tenant is in default under the
terms of the Lease, nor has the Lease been modified or amended except as recited or set forth in this Twelfth Addendum
|-- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In
witness whereof, Landlord and Tenant have executed this Twelfth Addendum on the dates set forth with their signatures below.
