 SUBLEASE AGREEMENT 
  
 THIS SUBLEASE AGREEMENT (“Sublease”) is entered as of the Effective Date by and between Sublessor and
Sublessee. 
  
 THE PARTIES ENTER this Sublease on the basis
of the following facts, understandings and intentions: 
  
 A.    Master Landlord is the current Landlord of the Premises. Sublessor is presently the Tenant of the Premises pursuant to the Master Lease. A copy of the Master Lease with all amendments, exhibits and addenda thereto,
is attached hereto as Exhibit A and, except as set forth in this Sublease, incorporated herein by this reference. 
  
 B.    Sublessor and Sublessee are parties to a certain sublease effective as of June 24, 2002 whereby Sublessor subleases Suite 950 to
Sublessee (the “950 Lease”) and, pursuant to Article 16 of the 950 Lease, Sublessee has a right of first offer for the Premises (the “Right of First Offer”). 
  
 C.    Pursuant to a letter dated February 25, 2003 Sublessee has chosen to exercise its Right of First
Offer. 
  
 D.    Sublessor desires to sublease
the Premises to Sublessee and Sublessee desires to sublease the Premises from Sublessor on all of the terms, covenants and conditions set forth herein. 
  
 E.    All of the terms and definitions of the Basic Sublease Information of this Sublease are incorporated herein by this reference.
Unless otherwise defined herein or the context otherwise requires, all capitalized terms shall have the meanings given them in the Master Lease. 
  
 NOW, THEREFORE, IN CONSIDERATION of the above facts, the mutual covenants and promises of the parties, and for other good and valuable
consideration the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows: 
  
 ARTICLE 1 - PREMISES 
  
 1.1    Demise of Premises.    Sublessor hereby subleases to Sublessee and Sublessee hereby subleases from Sublessor the Premises, for the Term and upon all of the
terms and conditions herein set forth. The Premises shall be used by Sublessee for those uses specifically set forth in the Basic Sublease Information, subject to the terms and conditions of the Master Lease, including Section 7 of the Master Lease.
In addition, Sublessor shall lease to Sublessee, and Sublessee shall lease from Sublessor, the storage space relating to the Storage Agreement attached as Exhibit D hereto (the “Storage Space”), the personal property set forth on
Exhibit C hereto (the “Exhibit C Property”) and any and all permanent improvements in or on the Premises (all of the foregoing collectively, the “Improvements”) constructed and/or owned by Master Landlord and/or Sublessor
upon all of the terms, covenants and conditions herein contained. As used herein, “Premises” shall include the Premises, the Storage Space and the Improvements. The Premises represents twenty-four (24%) of 
  

 1 









 
the total space in the Existing Premises, which shall be Sublessee’s “Proportionate Share” of Additional Rent (as defined in the Basic
Sublease Information). It is understood that Sublessee shall accept the Premises on the Commencement Date in “as is” condition. 
  
 1.2    Condition of Premises. 
  

1.2.1    Physical Condition.    Sublessor will deliver the Premises to Sublessee in its current
“as-is” condition as of the Effective Date. As of the Effective Date, Sublessee acknowledges that Sublessee has conducted Sublessee’s own investigation of the Premises and the physical condition thereof, which in Sublessee’s
judgment affect or influence Sublessee’s use of the Premises and Sublessee’s willingness to enter this Sublease and that, except as otherwise expressly set forth herein, neither Sublessor nor any of its employees or agents have made or
shall have any liability for any representations or warranties, express or implied, with respect to the condition of the Premises. Except as otherwise expressly set forth herein, by occupying the Premises on the Commencement Date, Sublessee shall be
deemed to have acknowledged that it accepts the Premises in their current condition. Sublessee agrees on the last day of the Sublease Term to surrender the Premises unto Sublessor in accordance with Article 15 of this Sublease. 
  
 1.2.2    No
Representations.    Sublessee and Sublessor recognize and agree that Sublessor would not sublease the Premises to Sublessee and Sublessee would not sublease the Premises from Sublessor except on an “as is” basis
and acknowledges that neither Sublessee nor Sublessor has made any representations of any kind, express or implied, in connection with the Improvements or physical conditions on, or bearing on, the Premises, including without limitation the
suitability of the Premises for Sublessee’s purposes. Sublessee further recognizes and agrees that neither Sublessor nor Master Landlord shall be required to perform any work of construction, alteration or maintenance of or to the Premises
except as expressly set forth herein. Notwithstanding the foregoing, Sublessee shall not be required to construct or pay the cost of complying with any covenants, conditions, restrictions, encumbrances, rules, regulations, statutes, ordinances, laws
or building codes requiring construction or improvements to any alterations, improvements or additions to the Premises that were made by Sublessor and are properly capitalized under general accounting principles, unless such compliance is
necessitated solely because of Sublessee’s particular use of the Premises. 
  
 1.3    Validation of Master Lease.    Sublessor hereby warrants that the Master Lease attached hereto as Exhibit A is complete and in full force and effect,
and that Sublessor is not in material default thereunder beyond expiration of any applicable cure or notice period, that, to the knowledge of Sublessor, (i) no other party to the Master Lease is in breach or default thereof, (ii) the area which is
the subject of the Sublease has not been previously assigned or subleased by Sublessor, and (iii) no other party has a legal right to occupy such area. 
  
 ARTICLE 2 - TERM 
  
 The term of this Sublease shall be for the Term set forth in the Basic Sublease Information provided that upon full execution of this Sublease by
Sublessor and Sublessee, and on or before the Commencement Date Sublessee provides Sublessor with (i) the certificates evidencing the insurance 
  

 2 









 
required by Article 9 of this Sublease, (ii) the first month’s Base Rent and Storage Space Rent and (iii) the Security Deposit. 
  
 ARTICLE 3 - SUBLESSEE’S PAYMENT OBLIGATIONS 
  
 3.1    Monthly Base
Rent.    The Monthly Base Rent and the Storage Space Rent shall be payable in advance in equal monthly installments in accordance with the Monthly Base Rent and the Storage Space Rent set forth in the Basic Sublease
Information, commencing with the Rent Commencement Date. Upon the execution of this Sublease by Sublessor and Sublessee, Sublessee shall deposit with Sublessor prepaid Rent in an amount equal to Two Thousand-Seven Hundred Seventy Two Dollars and
Sixty Five Cents ($2,772.65) for the first month’s Monthly Base Rent due following once the one calendar month Monthly Base Rent abatement period set forth in the Basic Sublease Information and One Hundred and Thirty Four Dollars and Forty
Cents ($134.40) for the first month’s Storage Space Rent (“Prepaid Rent”) (for avoidance of doubt, the parties hereby agree and acknowledge that there is not a one month abatement period for the Storage Space Rent). Sublessee shall
thereafter pay to Sublessor the Monthly Base Rent and the Storage Space Rent in advance, on or before the first day of each month, beginning on the first day of the calendar month succeeding the Rent Commencement Date. Monthly Base Rent, Storage
Space Rent and any additional rent due hereunder shall be payable to Sublessor, without further notice or demand and without deduction or offset, in lawful money of the United States of America at the address specified in the Basic Sublease
Information or at such other address as Sublessor may from time to time designate in writing. If the Term shall end on a day other than the last day of a calendar month, then Rent for the last month of the Term shall be prorated on a per diem basis,
with respect to the portions of the last fractional calendar month included in the Term. 
  
 3.2    Additional Rent.    In addition to Monthly Base Rent and Storage Space Rent, Sublessee shall be responsible for (a) Sublessee’s Proportionate Share of
the Additional Rent (as set forth in the Basic Sublease Information), it being the intent of the parties hereto that Sublessee shall owe no Operating Expenses (as defined in the Master Lease) to Sublessor applicable to calendar year 2003, (b)
Sublessee Taxes (as defined below) and (c) all other additional rent which may be imposed, at any time, on Sublessor with respect to the Premises pursuant to the Master Lease; provided that Sublessee shall not be responsible for any penalties,
interest or other costs incurred by Sublessor under the Master Lease that are caused by (i) Sublessee’s failure to pay rent to Master Landlord in a timely manner in accordance with the Master Lease, unless such failure is cause by
Sublessee’s default or failure to make timely payments to Sublessor in accordance with this Sublease, or (ii) a breach of the Master Lease or Sublease by, or the acts or negligence of Sublessor or its agents, representatives, sublessees,
employees or invitees (except to the extent such breach, negligence or acts were caused by Sublessee or its agents, representatives, sublessees, employees or invitees). As used herein, “Sublease Rent” shall include Base Rent, Storage Space
Rent, Sublessee’s Proportionate Share of Additional Rent, Sublessee Taxes and all other amounts payable by Sublessee to Sublessor hereunder. Sublessee shall be responsible for the Sublessee Rent for each and every month of the Sublease Term
commencing with the Rent Commencement Date. Sublessee shall pay its Proportionate Share of Additional Rent and Sublessee Taxes no later than thirty (30) days following Sublessee’s receipt of written demand therefor. 
  

 3 









 “Sublessee Taxes” shall consist of all taxes, fees or charges levied or assessed against or
attributable to any personal property or trade fixtures in the Premises or by reason of leasehold improvements. If any such taxes, fees or charges are included in Sublessor’s or Master Landlord’s taxes, Sublessor may pay them regardless of
the validity (under proper protest, if requested by Sublessee and at Sublessee’s sole cost and expense), and Sublessee will pay Sublessor the amount of Sublessor’s or Master Landlord’s taxes, as applicable, attributable to Sublessee,
as determined in good faith by Sublessor. 
  
 3.3    Security Deposit.    Upon the execution of this Sublease by Sublessor and Sublessee, Sublessee shall pay to Sublessor the Security Deposit set forth on the Basic Sublease
Information. Sublessor may (but shall not be required to) use the Security Deposit or any portion thereof to cure any defaults on the part of Sublessee (beyond any applicable cure period) or to reasonably compensate Sublessor for any damage
Sublessor incurs as a result of Sublessee’s failure to perform any of its covenants or obligations hereunder (provided Sublessee has been given any required notice and opportunity to cure such failure as set forth under the terms of this
Sublease), it being understood that any use of the Security Deposit shall not constitute a bar or defense to any of Sublessor’s remedies under this Sublease, at law or in equity. In such event, and upon written notice from Sublessor to
Sublessee specifying the amount of the Security Deposit so utilized by Sublessor and the particular purpose for which such amount was applied, Sublessee shall immediately deposit with Sublessor an amount sufficient to return the Security Deposit to
the amount specified in the Basic Sublease Information. Upon termination or earlier expiration of this Sublease, the Security Deposit shall be returned to Sublessee within the designated period under applicable law, reduced by those amounts that may
be required by Sublessor to remedy defaults on the part of Sublessee in the payment of Sublessee Rent, to repair damage to the Premises and to clean the Premises to a broom-clean condition. Sublessor shall hold the Security Deposit for the foregoing
purposes; provided, however, that Sublessor shall have no obligation to segregate the Security Deposit from its general funds or to pay interest thereon. 
  
 ARTICLE 4 - INTENTIONALLY LEFT BLANK 
  
  
 ARTICLE 5 - USE 
  
 The Premises are to be used for the Permitted Uses, and for no other purpose
or business without the prior written consent of Sublessor. In no event shall the Premises be used for a purpose or use prohibited by the Master Lease or the Storage Agreement. 
  
 ARTICLE 6 - RIGHTS AND DUTIES OF SUBLESSEE 
  
 6.1    Sublease Subject o Master Lease.    It is expressly understood,
acknowledged and agreed by Sublessee that this Sublease shall incorporate by reference the terms, conditions and covenants of the Master Lease and the Storage Agreement, except as excluded in Section 6.2 below, modified as appropriate in the
circumstances so as to make such Sections applicable only to the subleasing hereunder by Sublessor of the Premises during the Term of this Sublease. Sublessee shall be subject to, bound by and comply with all of said Sections of the Master Lease and
the Storage 
  

 4 









 
Agreement with respect to the Premises accruing during the Term of this Sublease, and shall satisfy all such terms and conditions of the Master Lease and the
Storage Agreement for the benefit of both Sublessor and Master Landlord, it being understood and agreed that wherever in the Master Lease or in the Storage Agreement the word “Tenant” appears, for the purposes of this Sublease, the word
“Sublessee” shall be substituted (subject to the limitations set forth in this Sublease), wherever in the Master Lease or the Storage Agreement the word “Landlord” appears, for the purposes of this Sublease, the words
“Master Landlord” (and, as applicable hereunder, “Sublessor”) shall be substituted; and wherever in the Master Lease the word “Premises” appears or wherever in the Storage Agreement the word “Storage Area”
appears, for the purposes of this Sublease, the words “Master Premises” shall be substituted; and that upon the breach of any of said terms, conditions or covenants of the Master Lease or Storage Agreement by Sublessee or upon the failure
of Sublessee to pay the Sublease Rent or comply with any of the provisions of this Sublease, Sublessor may exercise any and all rights and remedies granted to Master Landlord by the Master Lease or the Storage Agreement, as the case may be.
Sublessee expressly acknowledges, notwithstanding anything to the contrary in this Sublease, that Sublessee’s duty to indemnify, defend and hold Sublessor harmless from and against any and all fines, suits, losses, costs, expenses, liabilities,
claims, demands, actions, damages and judgments pursuant to this Sublease, and as more specifically set forth in Section 14 of the Master Lease and in Section 4 of the Storage Agreement, shall include Sublessor’s duty to indemnify, defend,
protect and hold Master Landlord harmless from and against any and all fines, suits, losses, costs, expenses, liabilities, claims, demands, actions, damages and judgments. 
  
 It is further understood and agreed that Sublessor has no duty or obligation to Sublessee under the aforesaid Sections of
the Master Lease or the Storage Agreement other than to maintain the Master Lease and the Storage Agreement in full force and effect during the term of this Sublease and to pay the difference between the Sublease Rent and the rent due and payable
under the Master Lease and the Storage Agreement; provided, however, that Sublessor shall not be liable to Sublessee for any earlier termination of the Master Lease or the Storage Agreement which is not due to the fault of Sublessor. In the event of
any conflict between this Sublease and the Master Lease or the Storage Agreement, the Sublease shall control, as between Sublessor and Sublessee. Whenever the provisions of the Master Lease or the Storage Agreement incorporated as provisions of this
Sublease require the written consent of Landlord or notice to Landlord, said provisions shall be construed to require the written consent and/or notice of both Master Landlord and Sublessor. Sublessee hereby acknowledges that it has read and is
familiar with all the terms of the Master Lease and the Storage Agreement, and agrees that this Sublease is subordinate and subject to the Master Lease and the Storage Agreement and that any termination thereof without the fault of Sublessor shall
likewise terminate this Sublease. 
  
 6.2    Exclusions.    The terms and provisions of the following Sections of the Original Lease are not incorporated into this Sublease: The first and second paragraphs of Section 2,
Sections 3 through 5, 8, 9(a), 10.1(b), 14, 24.1, the second sentence of Section 26.7 and the third paragraph of Section 10.2. The terms and provisions of the following Sections of the Amendment are not incorporated into this Sublease: Sections 1.2,
2.2, and 3 through 8. The terms and provisions of the following Sections of the Storage Agreement are not incorporated into this Sublease: 2 and 7. 
  

 5 









 6.3    Time for Notice.    The time limits provided
for in the provisions of the Master Lease or the Storage Agreement for the giving of notice, making of demands, performance of any act, condition or covenant, or the exercise of any right, remedy or option, are amended for the purposes of this
Sublease by lengthening or shortening the same in each instance by five (5) days, as appropriate, so that notices may be given, demands made, or any act, condition or covenant performed, or any right, remedy or option hereunder exercised, by
Sublessor or Sublessee, as the case may be, within the time limit relating thereto contained in the Master Lease or the Storage Agreement. If the Master Lease or the Storage Agreement allows only five (5) days or less for Sublessor to perform any
act, or to undertake to perform such act, or to correct any failure relating to the Premises or this Sublease, then Sublessee shall nevertheless be allowed three (3) days to perform such act, undertake such act and/or correct such failure.

  
 6.4    Sublessor’s
Obligations.    It shall be the obligation of Master Landlord (i) to provide or cause to be provided all services to be provided by Landlord under the terms of the Master Lease and the Storage Agreement and (ii) to
satisfy all obligations and covenants of Master Landlord made in the Master Lease and the Storage Agreement. Sublessee acknowledges that Sublessor shall be under no obligation to provide any such services or satisfy any such obligations or
covenants; provided, however, Sublessor, upon written notice by Sublessee, shall attempt to enforce all obligations of Master Landlord under the Master Lease and the Storage Agreement, provided that Sublessee reimburses Sublessor for all reasonable
costs and expenses incurred in connection therewith (except as otherwise set forth in Section 1.2.2 hereof). Sublessor shall not amend, terminate or waive any provisions under the Master Lease or the Storage Agreement or make any elections, exercise
any right or remedy or give any consent or approval under the Master Lease or the Storage Agreement that could result in a substantial interference with Sublessee’s use of the Premises or materially increase Sublessee’s obligations or
decrease Sublessee’s rights under this Sublease without, in each instance, Sublessee’s prior written consent. 
  
 6.5    Use of Building Common Areas.    Sublessee shall comply with all reasonable and
non-discriminatory rules and regulations established by Sublessor with respect to use of the Common Areas, and shall insure compliance therewith by all of Sublessee’s employees, contractors and invitees. 
  
 6.6    Entry by
Sublessor.    Upon forty-eight (48) hours advance verbal or written notice (except in case of emergency where no such notice shall be required), Sublessor shall have the right to enter upon the Premises for purposes of
maintenance and repair, and to ensure compliance by Sublessee with its obligations pursuant to this Sublease. Sublessee shall provide Sublessor with two keys (including card keys, if applicable) to all doors of the Premises in order to facilitate
such entry. 
  
 ARTICLE 7 - LEASE AND PURCHASE OF PERSONAL
PROPERTY 
  
 During the Term, Sublessee shall have the
right, at no additional cost and expense to Sublessee, other than payment of the Sublessee Rent, to use the Exhibit C Property. On the last day of the Term of this Sublease, Sublessee shall purchase the Exhibit C Property, free and clear of all
liens and encumbrances, by delivering $1.00 to Sublessor pursuant to a General Warranty Bill of Sale in the form of Exhibit E hereto. Upon purchase, the Exhibit C Property shall be owned by 
  

 6 









 
Sublessee and Sublessee shall be responsible for removing the Exhibit C Property from the Premises in accordance with Article 15 hereof. 
  
 ARTICLE 8 - INDEMNIFICATION 
  
 Except to the extent resulting from the acts, negligence or breach of this
Sublease, the Master Lease or the Storage Agreement by Sublessor (where such breach is not caused by Sublessee), Sublessee covenants to indemnify, defend, protect and hold Sublessor, its agents, officers, employees, and contractors harmless from and
against (i) any and all claims, causes of action, obligations, liabilities, costs and expenses (including reasonable attorneys’ fees and costs) to the extent arising out of or in connection with Sublessee’s use or occupancy of the Premises
or the Common Areas before or after the commencement of the Term of this Sublease, and (ii) the breach of this Sublease (or, to the extent incorporated herein, the Master Lease or the Storage Agreement) by Sublessee, its employees, agents,
contractors or invitees. Sublessee’s obligations under this Article 8 shall survive the termination or earlier expiration of this Sublease. 
  
 ARTICLE 9 - INSURANCE 
  
 Sublessee covenants to obtain and maintain the insurance policies required to be maintained by Sublessor under Section 15 of the Master Lease naming
Sublessor as an additional insured; to provide Sublessor with certificates evidencing such insurance; and not to merit cancellation or termination of such required insurance policies without giving at least fifteen (15) days prior written notice to
Sublessor and Master Landlord. Sublessee shall deliver to Sublessor, from time to time and upon Sublessor’s or Master Landlord’s reasonable written request, certificates of insurance indicating that the required policies of insurance are
in full force and effect throughout the entire term of this Sublease. All insurance policies required to be carried by Sublessor pursuant to the Master Lease and the Storage Agreement shall be carried by Sublessee, covering Sublessee’s
liability, and all such policies shall be written in accordance with the requirements for such insurance set forth in Section 15 of the Master Lease. 
  
 ARTICLE 10 - DEFAULTS AND REMEDIES 
  
 In the event of a default by Sublessee, Sublessor shall have all of the rights and remedies against Sublessee as are set forth in Section 19 of the Master
Lease as though Sublessor were the landlord named therein and Sublessee was the tenant named therein. A default under this Sublease shall be deemed to be a default under the 950 Lease and shall provide the parties with all of the rights and remedies
thereunder. 
  
 ARTICLE 11 - NOTICES 
  
 All notices or correspondence provided for herein shall be in writing and
shall be sent by certified mail, postage prepaid, return receipt requested, or by a nationally-recognized overnight delivery company which provides a receipt evidencing delivery, in which event they shall be deemed received on the date of delivery
as evidenced by the receipt. The Master Landlord’s, Sublessor’s and Sublessee’s addresses for written notices required to be given hereunder shall be the addresses set 
  

 7 









 
forth in the Basic Sublease Information, or at such other place designated by advance written notice delivered in accordance with the foregoing. 

 
 ARTICLE 12 - ASSIGNMENT AND SUBLETTING 
  
 Sublessee shall not sell, assign, encumber, sublet, hypothecate or otherwise
transfer by operation of law or otherwise this Sublease or the Sublessor’s interest in and to the Premises except in accordance with Section 20 of the Master Lease as modified by this Sublease. 
  
 ARTICLE 13 - REPAIRS AND MAINTENANCE 
  
 Except to the extent constituting an obligation of the Master Landlord under
the Master Lease, Sublessee shall, at Sublessee’s sole expense, keep the Premises in good order and sanitary condition, and repair any damage thereto caused by Sublessee or Sublessee’s agents, employees, contractors or invitees. In
performing its obligations under this Article 13, Sublessee shall notify Sublessor and of any repairs that could affect the Systems serving the Building (exclusive of the Premises) and shall use contractors approved by Master Landlord, in its
reasonable discretion. Sublessee acknowledges that, except as otherwise expressly provided herein, Sublessor is under no duty to make repairs or improvements to the Premises, and Sublessee hereby waives any right it may have at law or in equity to
enforce the same. Notwithstanding the foregoing, to the extent Master Landlord is obligated under the Master Lease to make any maintenance or repairs in or to the Premises, Sublessor, upon written notice by Sublessee, shall attempt to enforce such
obligations of Master Landlord, provided that (except as provided in Section 1.2.3 hereof) Sublessee reimburses Sublessor for all reasonable costs and expenses incurred in connection therewith. Notwithstanding the foregoing, if such maintenance or
repairs affect the use and enjoyment of the Common Area, such costs and expenses of enforcement shall be paid by Sublessor and Sublessee in proportion to their relative interests in the Master Premises. 
  
 ARTICLE 14 - DAMAGE AND DESTRUCTION 
  
 14.1    Termination of Master
Lease.    If the Premises is damaged or destroyed and Master Landlord, Sublessor or Sublessee validly exercises any option to terminate the Master Lease or this Sublease as specifically provided for in the Master Lease or
this Sublease (or in the Master Lease as incorporated herein by reference), if any, this Sublease shall terminate as of the date of the termination of the Sublease by either party hereto or the date of the termination of the Master Lease.

  
 14.2    Continuation of
Sublease.    If the Master Lease is not terminated following any damage or destruction as provided above, this Sublease shall remain in full force and effect. Sublessee shall be obligated to fulfill any repair obligations
of Sublessor with respect to the Premises; provided, however, that (i) Sublessor shall use commercially reasonable means to enforce any obligation of Master Landlord to rebuild the Premises in accordance with the Master Lease; (ii) Sublessor shall
make available to Sublessee any insurance proceeds Sublessor receives as a result of damage or destruction of the Premises; and (iii) Sublessee shall be entitled to abatement of Sublessee Rent on a proportionate basis (based on the degree to which
Sublessee’s use of the Premises is impaired as compared to the impairment of Sublessor’s use of the Master Premises) to 
  

 8 









 
the extent that Sublessor’s Rent is abated under the Master Lease. In the event that the damage cannot reasonably be repaired by the date that is 90
days prior to the expiration of the Term of this Sublease, then either party may terminate this Sublease by written notice to the other party. Notwithstanding anything to the contrary contained herein, if such damage or destruction occurs and the
Premises can not be, or is in fact not, restored so that such damage or destruction does not unreasonably interfere with Sublessee’s normal business operations within 180 days following the date of such damage or destruction, Sublessee shall
have the right to terminate this Sublease immediately upon deliver of written notice to Sublessor. 
  
 ARTICLE 15 - SURRENDER OF PREMISES 
  
 Sublessee shall peaceably surrender the Premises to Sublessor upon expiration or earlier termination of this Sublease, broom-clean and in as good a
condition as when Sublessee took possession and Sublessee shall remove Sublessee’s personal property and any or all Alterations made by Sublessee (provided that Master Landlord or Sublessor so notified Sublessee in accordance with Section 10.2
of the Master Lease), upon the expiration or earlier termination of this Sublease and promptly repair all damage to the Premises caused by such removal. Unless Master Landlord or Sublessor requires their removal, all Alterations made to the Premises
by Sublessee shall remain upon and be surrendered with the Premises at the expiration or earlier termination of this Sublease. 
  
 If Sublessee abandons the Premises, any of Sublessee’s personal property left on the Premises shall be deemed to be abandoned, and, at
Sublessor’s option, title shall pass to Sublessor under this Sublease as by a bill of sale. If Sublessee abandons the Premises and Sublessor elects to remove all or any part of Sublessee’s personal property, the reasonable cost of removal,
including repairing any damage to the Premises or Building caused by such removal, shall be paid by Sublessee. The provisions of this Article 15 shall survive the expiration or earlier termination of this Sublease. 
  
 ARTICLE 16 - INTENTIONALLY LEFT BLANK 
  
  
 ARTICLE 17 - MISCELLANEOUS 
  
 17.1    Entire Agreement.    This Sublease, the 950 Lease and the applicable portions of the Master Lease and the Storage Agreement contained by reference herein, contain all of the
covenants, conditions and agreements between the parties concerning the Premises, and shall supersede any and all prior correspondence, agreements and understandings concerning the Premises, both oral and written. No addition or modification of any

 9 









 17.3    Master Landlord’s Consent.    This
Sublease is conditioned upon Master Landlord’s written approval of this Sublease prior to the Commencement Date. If Master Landlord refuses to consent to this Sublease, then this Sublease shall be deemed void and of no effect, in which event
the parties shall be discharged from all obligations hereunder and Sublessor shall return the Prepaid Rent, if previously delivered to Sublessor, to Sublessee. If Master Landlord does not provide consent to this Sublease on or before April 15, 2003
in a form of consent acceptable to Sublessee and Sublessor, each in its sole discretion, or if Sublessor is unable to tender possession of the Premises to Sublessee on or before April 15, 2003 (through no fault of Sublessor), then either party may
by written notice delivered to the other party no later than five (5) days following such date, have the right to terminate this Sublease, in which event the parties shall be discharged from all obligations hereunder and Sublessor shall return the
Prepaid Rent, if previously delivered to Sublessor, to Sublessee. 
  
 17.4    Authority.    Each person executing this Sublease on behalf of a party hereto represents and warrants that he or she is authorized and empowered to do so and to thereby bind the
party on whose behalf he or she is signing. 
  
 17.5    Attorneys’ Fees.    In the event either party shall bring any action or proceeding for damages or for an alleged breach of any provision of this Sublease to recover rents,
or to enforce, protect or establish any right or remedy hereunder, the prevailing party shall be entitled to recover reasonable attorneys’ fees and court costs as part of such action or proceeding. 
  
 17.6    Broker.    Sublessor shall be responsible for payment of any and all finder’s fees or commissions to CD Richard Ellis, Inc. and BT Commercial (“Brokers”) in
connection with this Sublease pursuant to a separate agreement. Each party warrants and represents that it has had no dealings with any real estate broker, agent or finder other than Brokers in connection with the negotiation of this Sublease, and
that it knows of no other real estate broker or agent who is entitled to any commission or finder’s fee in connection with the Premises or this Sublease. Each party shall indemnify and hold the other harmless from and against any and all
claims, demands, losses, liabilities, lawsuits, judgments, costs and expenses (including without limitation, attorneys’ fees and costs) arising from any claim for a leasing commission or equivalent compensation alleged to be owing on account of
the indemnifying party’s dealings with any real estate broker or agent in connection with the Premises or this Sublease. 
  
 17.7    Counterparts.    This Sublease may be executed in any number of counterparts, each of which
shall be deemed to be an original and all of which taken together shall comprise but a single instrument. 
  
 17.8    Severability.    If any provisions of this Sublease or the application of any provision of
this Sublease to any person or circumstance is, to any extent, held to be invalid or unenforceable, the remainder of this Sublease or the application of that provision to persons or circumstances other than those as to which it is held invalid or
unenforceable, will not be affected, and each provision of this Sublease will be valid and be enforced to the fullest extent permitted by law. 
  

 10 









 17.9    Governing Law.    This Sublease will be
governed by and in all respects construed in accordance with the laws of the State of California, without giving effect to any choice of law rule that would cause the application of the laws of any jurisdiction other than the State of California.

  
 17.10    Negotiated
Transaction.    The parties mutually acknowledge that this Sublease has been negotiated at arm’s length. The provisions of this Sublease shall be deemed to have been drafted by all of the parties and this Sublease
shall not be interpreted or construed against any party solely by virtue of the fact that such party or its counsel was responsible for its preparation.

maintenance, preservation, ownership and operation of the Development and its supporting facilities directly servicing the Development (as allocated to the Development in accordance with generally accepted accounting principles, consistently
applied) including, but not limited to, the following: 
  
 (a)    Wages, salaries and reimbursable expenses and benefits of all on-site and off-site personnel engaged in the operation, maintenance and security of the Development and the direct costs of training such employees,

and costs incurred by Landlord in any legal proceeding against any other specific tenant where such other tenant is responsible (either pursuant to its lease or at law) for payment of such fees and costs but is unwilling or is unable to pay such
fees and costs after reasonable efforts have been made by Landlord to pursue reimbursement from such tenant; provided, however, that legal expense shall not include the cost of (i) negotiating lease terms for prospective tenants, (ii) negotiating
termination or extension of leases with existing tenants, (iii) proceedings against any other specific tenant relating solely to the collection of rent or other sums due to Landlord from such tenant, or (iv) legal costs incurred in connection with
development and/or construction of the Development. 
  
 (h)    All insurance premiums and costs, including, but not limited to, the premiums and cost of fire, casualty, liability, rental abatement and earthquake insurance applicable to the Development and Landlord’s
personal property used in connection therewith (and all amounts paid as a result of loss sustained that would be covered by such policies but for commercially reasonable “deductible” or self-insurance provisions); provided, however, that
Landlord may, but shall not be obligated to, carry earthquake insurance (if Landlord elects to carry earthquake insurance, Tenant shall not be responsible for premium costs for such earthquake insurance in excess of premiums customarily charged for
earthquake insurance to landlords of similar buildings in the Northern San Mateo County area). 
  
 (i)    Repairs, replacements and general maintenance (except for repairs and replacements (i) paid for from the proceeds of insurance,
(ii) paid for directly by Tenant, other tenants or any third party, or (iii) for the benefit solely of tenants of the Development other than Tenant to the extent that Tenant could not obtain similar services from Landlord without an obligation to
reimburse Landlord for the entire cost thereof under the provisions of this Lease). 
  
 (j)     All real and personal property taxes and general and special assessments imposed by any governmental authority or agency on the Building and a pro rata portion of any taxes and general and
special assessments levied on the Development; any assessments levied in lieu of, or in substitution for, such taxes; and any other costs, fees or charges levied or assessed by, or at the direction of, any federal, state, or local government
authority in connection with the ownership, use or occupancy of the Development, whether or not now in effect or foreseeable (excluding penalties, fines and interest charges imposed as a result of Landlord’s failure to pay timely the same;
provided that, Tenant has timely paid its proportionate share of Operating Expenses hereunder); and any reasonable expenses, including the reasonable cost of attorneys or experts, incurred by Landlord in seeking reduction by the taxing authority of
the above-referenced taxes, less any tax refunds obtained on account of such taxes previously paid and for which Tenant has paid Tenant’s Share thereof as a result of an application for review thereof; provided, however, that such taxes shall
not 

  

 3 









 
include: (i) taxes paid by Tenant pursuant to Section 9 or by other tenants in the Development pursuant to similar provisions in their leases; or (ii)
franchise, transfer, inheritance, or capital stock taxes or income taxes measured by the net income of Landlord from all sources, unless, due to a change in the method of taxation, any of such taxes is levied or assessed against Landlord as a
substitute for, or as an addition to, in whole or in part, any other tax that would otherwise constitute the taxes described in the preceding provisions of this clause (j). 
  
 (k)    Amortization (together with reasonable financing charges) of capital improvements made to the
Development that (i) are or will be required to comply with applicable law, ordinance, rule or regulation, enacted or enforced after the Commencement Date; (ii) are replacements of items which Landlord is obligated to maintain; or (iii) are intended
to improve the operating efficiency of the Development, provided, however, that in the case of improvements made solely for efficiency purposes, the amount chargeable as an Operating Expense in any year shall not exceed Landlord’s reasonable
determination of the efficiency achieved either in direct cost savings, avoidance of cost increases or a combination of both. As used in this definition of Operating Expenses, “amortization” shall mean allocation of the cost equally to
each year of useful life of the items being amortized or a shorter period equal to the number of years required to recover the cost of said item of capital improvement out of the savings in operating efficiency derived therefrom. Notwithstanding the
foregoing, however, Landlord may treat as expenses (chargeable in the year incurred) and not as capital costs items that are less than two percent (2%) of estimated Operating Expenses for the year in question. 
  
 Notwithstanding any other provision herein to the contrary, if the
Development is not fully occupied during any year of the Term, an adjustment shall be made in computing Operating Expenses for such year so that Operating Expenses shall be computed as though the Development had been fully occupied during such year;

 2.    DEMISE 
  
 For the Term, Landlord leases the Premises to Tenant and Tenant leases the
same from Landlord, all upon and subject to the terms and conditions of this Lease. Tenant hereby acknowledges that Landlord may deliver to Tenant either the Suite 950 Space or the Suite 980 Space prior to the Estimated Commencement Date, whereupon
the Lease shall commence with respect to the space so delivered upon all the terms, covenants and conditions contained in this Lease, including without limitation the obligation to pay Rent for the space so delivered. Tenant hereby acknowledges that
if Landlord, for any reason whatsoever, cannot deliver possession of the Premises to Tenant on the Commencement Date or upon the full execution of this Lease, which ever is later, this Lease shall not be void or voidable by Tenant, nor shall
Landlord be liable to Tenant for any loss or damage resulting therefrom; provided, however, if Landlord fails to deliver to Tenant possession of both the Suite 950 Space and the approximately two thousand one hundred thirty-eight (2,138) square feet
of rentable area (being a portion of Suite 900 of the Building) being concurrently subleased to Tenant (the “Sublease Premises”) on or before August 1, 1999, then Tenant may, at its option and as its sole and exclusive remedy for such

written notice of such termination to Landlord by August 10, 1999 but before Landlord delivers to Tenant possession of both the Suite 950 Space and the
Sublease Premises. If Tenant so terminates this Lease, then Landlord shall immediately return to Tenant all amounts previously paid by Tenant to Landlord under this Lease (and under the sublease of the Sublease Premises, if applicable), excluding
any amounts that Tenant may owe to Landlord pursuant to the terms of this Lease and excluding any portion of the Security Deposit used by Landlord to cure any defaults on the part of Tenant or otherwise used by Landlord in accordance with the
provisions of Section 6 of this Lease, and thereafter neither party shall have any further obligations under this Lease, other than those obligations that expressly survive the termination or earlier expiration of this Lease. If Tenant fails to so
terminate this Lease, this lease shall not terminate but shall remain in full force and effect upon the same terms and conditions set forth in this Lease. 
  
 If Landlord falls to deliver to Tenant possession of the Suite 980 Space on or before August 1, 1999, then, Tenant may, at is option and as its sole and
exclusive remedy for such failure, terminate this Lease for the Suite 980 Space by delivering written notice of such termination to Landlord by August 10, 1999 but before Landlord delivers to Tenant possession of the Suite 980 Space. If Tenant so
terminates this Lease for the Suite 980 Space, then Landlord shall immediately return to Tenant all amounts previously paid by Tenant to Landlord under this Lease for the Suite 980 Space, excluding any amounts that Tenant may owe to Landlord
pursuant to the terms of this Lease for the Suite 980 Space and excluding any portion of the Security Deposit for the Suite 980 Space used by Landlord to cure any defaults on the part of Tenant or otherwise used by Landlord in accordance with the
provisions of Section 6 of this Lease, and thereafter neither party shall have any further obligations under this Lease for the Suite 980 Space, other than those obligations that expressly survive the termination or earlier expiration of this Lease,
and if Tenant has not terminated the Lease in accordance with the provisions of the immediately foregoing paragraph of this Section 2, this Lease with regard to the Suite 950 Space shall remain in full force and effect upon the terms, covenants and
conditions specified in this Lease and thereafter the “Premises” shall mean the Suite 950 Space and all calculations based upon the square footage of the Premises shall be adjusted to include only the Suite 950 Space. If Tenant fails to
terminate this Lease for the Suite 980 Space in accordance with the provisions of this Section 2 and if Tenant has not terminated this Lease in accordance with the provisions of the immediately foregoing paragraph of this Section 2, then the Lease
for the Suite 980 Space (and for the Suite 950 Space) shall not terminate but shall remain in full force and effect upon the same terms and conditions set forth in this Lease. 
  
 So long as it is entitled to possess the Premises, Tenant may (with others) use the Common Areas on a non-exclusive basis
for their intended purposes; provided, however, Landlord shall have the sole and exclusive right to possession and control of the Common Areas. So long as reasonable access and services (including Tenant’s parking spaces described in the Lease
Summary) to the Premises are available, Landlord may (a) install, use, maintain, repair, relocate and replace pipes, duds, conduits, wires and appurtenant meters and equipment; (b) change the Common Areas, including, without limitation, the
location, size, shape and number of driveways, entrances, parking spaces, parking areas, loading and unloading areas, ingress, egress, direction of traffic, landscaped areas and walkways; (c) close temporarily, or eliminate permanently, any Common
Areas 
  

 6 









 
(d) designate other land as Common Areas; (e) add additional buildings and improvements to the Common Areas, and lease such buildings and improvements and/or
existing buildings and Improvements on the Common Areas; (f) use the Common Atlas in making expansions, additional improvements, repairs or alterations to any part of the Development; and (g) do and perform such other acts and make such other
changes in, to or with respect to the Development as Landlord may, in the exercise of sound business judgment, deem to be appropriate. 
  
 3.    ACCEPTANCE OF PREMISES 
  
 Tenant hereby acknowledges that the Premises is leased to Tenant in its present “as-is” condition, and Landlord
shall have no obligation to install any alterations, additions or improvements or do any work whatsoever to the Premises. Tenant further acknowledges that it is currently in possession of the Suite 950 Space pursuant to an assignment of that certain
Gateway Office Building Lease dated September 15, 1989, by and between Homart Development Co., a Delaware corporation, Landlord’s predecessor in interest, and Shakey’s Incorporated, a Delaware corporation (“Shakey’s”), as
amended (collectively, the “Shakey’s Lease”). Concurrently with the execution of this Lease, Landlord, Tenant and Shakey’s are executing an agreement terminating the Shakey’s Lease and the assignment thereof by Shakey’s
to Tenant (the “Shakey’s Lease Termination Agreement”). Notwithstanding anything to the contrary contained in this Lease, Tenant and Landlord hereby acknowledge that this Lease is expressly conditioned upon Tenant and Shakey’s
executing and delivering to Landlord the Shakey’s Lease Termination Agreement in a form reasonably acceptable to Landlord. If for any reason the Shakey’s Lease is not terminated pursuant to the Shakey’s Lease Termination Agreement,
this Lease shall terminate and thereafter neither party shall have any further obligation under this Lease, except for those obligations which by their terms survive the termination of this Lease. 
  
 The current tenant of the Suite 980 Space (the “Suite 980 Tenant”)
is executing a lease termination agreement (the “Suite 980 Lease Termination Agreement”), which Suite 980 Lease Termination Agreement shall terminate the current lease for the Suite 980 Space (the “Suite 980 Lease”). Tenant and
Landlord hereby acknowledge that this Lease as it relates to the Suite 980 Space only is expressly conditioned upon the Suite 980 Tenant’s executing and delivering to Landlord the Suite 980 Lease Termination Agreement in a form reasonably
acceptable to Landlord. If for any reason the Suite 980 Lease is not terminated pursuant to the Suite 980 Lease Termination Agreement, this Lease with respect to the Suite 980 Space only shall terminate and thereafter neither party shall have any
further obligation under this Lease for the Suite 980 Space, except for those obligations which by their terms survive the termination of this Lease, and this Lease with regard to the Suite 950 Space shall remain in full force and effect upon the
terms, covenants and conditions specified in this Lease and thereafter the “Premises” shall mean the Suite 950 Space and all calculations based upon the square footage of the Premises shall be adjusted to include only the Suite 950 Space.

  
 4.    RENT 
  
 From the Commencement Date, Tenant will pay Landlord, at the address
specified in the Lease Summary or at such other address as may be designated by Landlord from time to time and 
  

 7 









 
without prior notice, demand, offset or deduction (except as otherwise expressly set forth herein), the following rent: 
  
 4.1    Base Rent 
  
 Tenant shall pay the Base Rent in advance on the first day of each month
doing the Term hereof, except that the first full month’s Base Rent shall be paid upon execution of this Lease. If the Term commences on other than the first day of a month, the Base Rent provided for such partial month shall be prorated and
the prorated installment shall be paid on the first day of the calendar month succeeding the Commencement Date. If the Term terminates on other than the fast day of a calendar month, the Base Rent provided for such partial month shall be prorated
and the prorated installment shall be paid on the first day of the calendar month preceding the Termination Date. 
  
 4.2    Additional Rent 
  
 Tenant shall pay as additional rent (“Additional Rent”) Tenant’s Share of Operating Expenses in excess of the Operating Expense Base
multiplied by the Rentable Area. For partial years, the Operating Expenses will be calculated on a full-year basis, and then prorated. Tenant shall pay monthly installments of Additional Rent on the first day of each month, in amounts specified in
good faith by Landlord from time to time, which, by the end of each year (or by the Termination Date, if earlier), will total Landlord’s estimate of Additional Rent paid for such year. By the following April 1, or as soon thereafter as
practicable, Landlord will furnish Tenant a statement of Operating Expenses and Additional Rent for such year. Any amounts owing for that year shall, within thirty (30) days thereafter, be paid by Tenant to Landlord. Any amounts overpaid shall, at
Landlord’s option, be credited against the next installment(s) of Additional Rent due from Tenant, or be refunded to Tenant. This obligation survives termination or the earlier expiration of this Lease. 
  
 5.    SECURITY DEPOSIT 

 
 Concurrently with execution hereof, Tenant shall pay to Landlord the
Security Deposit set forth on the Lease Summary as security for the full and faithful performance of Tenant’s obligations under this Lease, which amount shall be paid as follows: Landlord shall credit to the Security Deposit the amount of
Twelve Thousand Two Hundred Thirty-Six and 40/100ths Dollars ($12,236.40), which Tenant paid to Landlord as a security deposit pursuant to the Shakey’s Lease; and Tenant shall pay to Landlord the amount of Fifteen Thousand Nine Hundred
Eighty-One and 45/100ths Dollars ($15,981.45). Landlord may (but shall not be required to) use the Security Deposit or any portion thereof to core any defaults on the part of Tenant or to compensate Landlord for any damage Landlord incurs as a
result of Tenant’s failure to perform any of its covenants or obligations hereunder, it being understood that any use of the Security Deposit shall not constitute a bar or defense to any of Landlord’s remedies under this Lease, at law or
in equity. In such event, and upon written notice from Landlord to Tenant specifying the amount of the Security Deposit so utilized by Landlord and the particular purpose for which such amount was applied, Tenant shall immediately deposit with
Landlord an amount sufficient to return the Security Deposit to the amount specified in the Basic Lease Information. Upon termination or earlier expiration of this Lease, the Security Deposit shall be returned to Tenant, reduced by those amounts
that may be required by 
  

 8 









 
Landlord to remedy defaults on the part of Tenant in the payment of Rent, to repair damage to the Premises caused by Tenant or Tenant Parties and to clean
the Premises to a broom-clean condition. The portion of the Security Deposit not so required shall be paid over to Tenant promptly after expiration of the Term. Landlord shall hold the Security Deposit for the foregoing purposes; provided, however,
that Landlord shall have no obligation to segregate the Security Deposit from its general funds or to pay interest thereon. If Landlord conveys or transfers its interest in the Building, and as a part of such conveyance or transfer, assigns its
interest in this Lease and Security Deposit and the transferee assumes the same in writing, or any portion thereof not previously applied, the Security Deposit shall be transferred to Landlord’s successor and Landlord shall be released and
discharged from any further liability to Tenant with respect to such Security Deposit. In no event shall any Mortgagee under a Mortgage, or any purchaser of all or any portion of the Development at a public or private foreclosure sale under a
Mortgage, have any liability or obligation whatsoever to Tenant or Tenant’s successors or assigns for the return of all or any part of the Security Deposit in the event any such Mortgagee or purchaser becomes a mortgagee in possession or
succeeds to the interest of Landlord under this Lease unless, and then only to the extent that, such Mortgagee or purchaser has received all or any part of the Security Deposit. 
  
 6.    SERVICES PROVIDED BY LANDLORD 
  
 Landlord agrees to furnish or cause to be furnished to the Premises the
utilities and services as described in Exhibit C, subject to the standards set forth therein. Tenant shall obtain all utilities and services from vendors designated by Landlord, which vendors shall be selected in Landlord’s sole and absolute
discretion, and Tenant shall have no right to obtain any utilities or services from any vendors other than those so designated by Landlord; provided, however, in no event shall Tenant be responsible for any charges from such venders in excess of the
costs charged by similar, reputable venders of such services to buildings in the Northern San Mateo County area comparable to the Building and otherwise consistent with an arms’-length agreement In the event any rule or regulation of applicable
utilities or governmental authority restricts the services to be provided hereunder, Landlord shall not be in default hereof and Tenant shall not be entitled to an abatement of Rent. Landlord does not warrant that the services provided for in this
Section 6 will be free from any irregularity or stoppage. Landlord shall use commercially reasonable efforts to correct the same, but no such condition or event will curate any liability for Landlord or Landlord Parties, or constitute an eviction,
actual or constructive, of Tenant, or cause any abatement of the rent payable under this Lease or relieve Tenant of any of its obligations under this Lease. Notwithstanding any other provision in this Paragraph 6 to the contrary, if such utilities
or services shall, by reason of Landlord’s negligence or willful misconduct and through no fault of Tenant, be interrupted or suspended and not restored within three (3) business days after written notice from Tenant to Landlord, and if by
reason of such interruption or suspension Tenant is unable to conduct its business operations from the Premises, then Landlord shall refund to Tenant an amount equal to the Base Rent (prorated on a daily basis) paid by Tenant for the period from the
date of such interruption or suspension until such service is restored or reasonably satisfactory alternative service is provided in its place.

(a)    Subject to Sections 4.2, 10.1(6), 17 and 18, Landlord shall repair and maintain (i) the structural portions of the Building,
(ii) the exterior walls of the Building, including glass and glazing, (iii) the roof, (iv) those portions of the mechanical, electrical, plumbing. HVAC and life safety systems serving the Building (the “Systems”) (excluding any connections

 12 









 10.2    Alterations 
  
 Tenant will not make or permit alterations, improvements or additions
(including fixtures) in or to the Premises (collectively “Alterations”) without Landlord’s prior written consent, which consent shall not be unreasonably withheld. Tenant’s request for such consent shall be in writing,
accompanied by proposed detailed plans and specifications. Landlord may require Tenant to provide Landlord, at Tenant’s sole cost and expense, a lien and completion bond in an amount equal to one and one-half times the estimated cost of such
Alterations, to insure Landlord against any liability for any mechanic’s and materialmen’s liens and to insure completion of the work. Alterations will be performed, if Landlord elects, by Landlord or a contractor designated by Landlord,
at Tenant’s sole cost and expense. Tenant may engage its own contractors to perform remodel work upon written approval by Landlord. In such event, Landlord shall charge a fifteen percent (15%) administrative fee on all construction costs. Any
and all plans must be submitted to landlord for approval, and building permits must be obtained by Tenant prior to commencement of any construction remodeling. Subject to Section 24.1, all Alterations will become Landlord’s property and a part

governmental agencies, furnishing a copy thereof to Landlord prior to the commencement of the work, and compliance by Tenant with all conditions of said permits and approvals in a prompt and expeditious manner. Unless Landlord so specifies when it

by Tenant, and Landlord shall have the right to post notices of non-responsibility in or on the Premises or other parts of the Development as provided by law. All Alterations, repairs and replacements by Tenant shall be in accordance with all
applicable laws, rules and ordinances and the requirements of any insurance carrier, and shall be of a quality and class at least equal to the original work, performed in a good and workmanlike manner with good grades of materials approved by
Landlord. Tenant will give Landlord opportunity to inspect and monitor all work. Tenant shall provide Landlord with as-built plans and specifications for Alterations promptly upon their completion. Should Tenant make any Alterations without
Landlord’s prior written approval, or in violation of such approval or the requirements of this Section 10.2, Landlord may, at any time during the Term, either remove any part or all of the same on Tenant’s behalf or require that Tenant do
so all at Tenant’s sole cost and expense. All reasonable costs incurred by landlord in removing any such alterations shall be repaid by Tenant to Landlord immediately upon demand, together with an administrative fee equal to fifteen percent
(15%) of such costs. 
  
 Subject to the teens of this Section
10.2, Landlord hereby consents to Tenant (i) upon delivery to Tenant of both the Suite 950 Space and the Sublease Premises, removing the current 
  

 13 









 
demising wall that separates the Suite 950 Space from the Sublease Presses (the “Sublease Demising Wall”), (ii) upon delivery by Landlord to Tenant
of both the Suite 950 Space and the Suite 980 Space, removing the current demising wall that separates the Suite 950 Space from the Suite 980 Space (the “Suite 980 Demising Wall”) and (iii) making minor Alterations that may be required in
connection with the removal of each of the Sublease Demising Wall and the Suite 980 Demising Wall (collectively, the “Demising Alterations”); provided, however, and notwithstanding anything to the contrary contained herein, upon the
expiration or earlier termination of the Term, Tenant, at Landlord’s request, shall remove any Demising Alterations and repair any damage to the Suite 950 Space, the Sublease Premises and/or the Suite 980 Space as a result of the Demising
Alterations and Tenant shall reconstruct the Sublease Demising Wall and the Suite 980 Demising Wall each to the same condition in which each existed at the commencement of the Term. Landlord hereby agrees to reimburse Tenant for the out-of-pocket
costs Tenant actually incurs for the Demising Alterations and for any Broker Fees as set forth in Section 8, but in no event shall Landlord’s reimbursement obligation pursuant hereto, in the aggregate, exceed Thirty Thousand Dollars
($30,000.00) (the “Allowance”). All costs in excess of the Allowance shall be the sole responsibility of Tenant. Landlord shall make such reimbursement to Tenant within thirty (30) days after Tenant delivers to Landlord written demand
supported by invoices, receipts and other documents reasonably acceptable to Landlord as evidence of the lien-free completion of said improvements in accordance with the provisions of this Lease and all applicable laws and as evidence of the payment
of Broker Fees by Tenant, as applicable. Any and all costs not properly submitted to Landlord by May 31, 2000 shall not be reimbursable hereunder and shall be at Tenant’s sole cost and expense. Any excess allowance not properly claimed by
Tenant pursuant hereto shall, after May 31, 2000, be forfeited by Tenant and remain the exclusive property of the Landlord. 
  
 11.    LIENS 
  
 Tenant shall not permit any lien to exist on or against any part of the Development allegedly resulting from any work or materials furnished or
obligations incurred by or for Tenant. Tenant shall discharge any such lien of record or post a bond in accordance with applicable law as soon as reasonably possible after such lien is filed; provided, however, if no liens are allowed pursuant to
Landlord’s Mortgage now or hereafter existing on any part of the Building or the Development, Tenant shall discharge any such lien of record immediately upon its filing. Neither this Lease, nor any request or consent of Landlord to the labor,
materials or obligations, shall be a consent to any such lien. Landlord may keep posted on the Premises any notices it deems necessary for protection from such liens. If Tenant fails to discharge any such lien, or to post a bond, or to contest such
lien by appropriate legal proceeding, or if any such lien jeopardizes Landlord’s interest in the Development or is otherwise prohibited by Landlord’s Mortgage now or hereafter existing on any part of the Building or the Development, then
Landlord may cause such lien to be released by any means it deems proper, including payment, at Tenant’s sole cost and expense and without affecting Landlord’s rights. All reasonable costs incurred by Landlord in causing such liens to be
released, together with an administrative fee equal to ten percent (10%) of such costs, shall be repaid by Tenant to Landlord within thirty (30) days after Landlord delivers to Tenant written demand supported by invoices or other reasonably
satisfactory evidence of such costs. 
  

 14 









 12.    ENTRY 
  
 Landlord may enter any part of the Premises at all reasonable hours following reasonable prior notice to Tenant (or in any
emergency or suspected emergency, at any hour, without notice), to (a) inspect, test, clean, or make repairs, alterations and additions to the Building or the Premises as Landlord believes appropriate, or (b) provide any service which Landlord is
now or hereafter obligated to furnish to tenants of the Building, or (c) show the Premises to prospective lenders, purchasers or tenants (but, with respect to tenants, only during the last six (6) months of the Term) and, if they are vacated, to
prepare them for reoccupancy. Rent will not abate because of Landlord’s entry. Landlord shall at all times have keys to all doors to or in the Premises. 
  
 13.    LANDLORD’S LIABILITY 
  
 Tenant will protect its property and the person and property of all Tenant Parties, and insure the same to its own
satisfaction (including at least the insurance required hereunder), and accordingly waives any claim against Landlord and the Landlord Parties for loss or damage to any property, injury to any person, or injury to Tenant’s business from any
cause except for any damages directly caused (and specifically excluding any consequential damages) by Landlord’s willful misconduct or reckless ads. Tenant, for itself and all Tenant Parties, assumes all risk of damage to person and property,
proximate or remote. All personal property on the Premises is at Tenant’s risk only; the Landlord shall not be liable for any damage to or theft of such property. 
  
 14.    INDEMNIFICATION AND EXCULPATION 
  
 Tenant shall indemnify, defend and hold Landlord and the Landlord Parties
(collectively, “Indemnitee”) harmless from and against any and all fines, suits, losses, costs, expenses, liabilities, claims, demands, actions, damages and judgments (collectively, “Liabilities”) suffered by, recovered from or
asserted against the Indemnitee, of every kind and character, resulting from any breach, violation or nonperformance by Tenant of any provision of this Lease, and from injury or damage to person or property incident to, arising out of or caused
(proximately or remotely, in whole or in part) by any act, omission, negligence or misconduct by Tenant or the Tenant Parties, or in any other way from Tenant or any Tenant Parties’ occupancy or use of or presence on the Development. If any
such proceeding is brought against an Indemnitee, Tenant will retain counsel reasonably satisfactory to Landlord to defend the Indemnitee at Tenant’s sole cost and expense. All such costs and expenses, including, without limitation,
attorneys’ fees and court costs, shall be payable by Tenant to Landlord immediately upon demand. Tenant’s obligations under this Section 14 shall survive the termination or earlier expiration of this Lease. 
  
 Landlord will indemnify, defend and hold Tenant harmless from all Liabilities
asserted against Tenant, to the extant that such Liabilities are proven by Tenant to have been caused by Landlord’s willful misconduct or reckless acts. Landlord’s obligations under this Section 14 shall include reimbursement to Tenant for
reasonable attorneys’ fees and court costs incurred by Tenant in connection with those Liabilities covered by Landlord’s indemnification as set forth herein. All costs and expenses, including attorneys’ fees and court costs, payable
by Landlord to Tenant under this Section 14 shall be payable to Tenant within thirty (30) days after Tenant delivers to Landlord 
  

 15 









 written demand supported by invoices or other reasonably satisfactory evidence of such expenses. Landlord’s
obligations under this Section 14 shall survive the termination or earlier expiration of this Lease. 
  
 15.    INSURANCE 
  
 Tenant, during the Term and any other period of occupancy, will at its sole cost and expense maintain insurance reasonably satisfactory to Landlord, but in any event complying with the following minimum requirements:

  
 (a)    General Liability insurance with
combined single limits not less than $2,000,000.00, for personal injury or death and property damage occurring in or about or related to the use or occupancy of the Development by Tenant and any Tenant Parties. 
  
 (b)    “All Risk” insurance for the full
replacement cost of all Alterations, all Tenant’s property on the Premises and all fixtures. Unless this lease is terminated upon damage or destruction, the proceeds of such insurance will be used to restore the foregoing. 
  
 (c)    Worker’s Compensation (as required by state
law), and Employer’s Liability insurance in the amount of not less than $500,000.00. 
  
 (d)    Loss of income and extra expense insurance in such amounts as will reimburse Tenant for direct or indirect loss of earrings or extra expenses attributable to all perils commonly insured
against by prudent tenants or attributable to prevention of access to the Development as a result of such perils. 
  
 All policies required hereunder will be issued by carriers rated A-VII or better by Best’s Key Rating Guide and licensed to do business in the State
of California. The policies shall name Landlord and any other person or entity that Landlord may designate from time to time as additional insureds, with primary coverage non-contributing to any insurance Landlord may carry, and shall provide that
coverage cannot be cancelled or materially changed except upon thirty (30) days prior written notice to Landlord and any additional insureds. At least thirty (30) days prior to expiration of such policies, and promptly upon any other request by
Landlord, Tenant shall furnish Landlord and any additional insureds with copies of policies, or certificates of insurance, evidencing maintenance and renewal of the required coverage. In the event Tenant does not maintain said insurance, Landlord
may, in its sole discretion and without waiving any other remedies hereunder, procure said insurance and Tenant shall pay to Landlord within thirty (30) days after written demand the cost of said insurance together with an administrative fee equal
to ten percent (10%) of such costs. 
  
 During the Term Landlord
shall insure the Building (excluding any property which Tenant is obligated to insure) against damage with All-Risk insurance and public liability insurance, all in such amounts and with such deductibles as Landlord in good faith considers
appropriate; provided, however, such All-Risk insurance shall be in an amount equal to at least the full replacement cost of the Building. Landlord may, but shall not be obligated to, obtain and carry any other form or forms 
  

 16 









 of insurance, including, without limitation, earthquake insurance (subject to the provisions of subparagraph (h) of the
definition of Operating Expenses), as Landlord or Mortgagees may determine advisable. Tenant has no right to receive any proceeds from any insurance policies carried by Landlord. Notwithstanding anything in the foregoing to the contrary; however,
Landlord may self-insure but only to the extent permitted under any Mortgage. 
  
 If any act or acts, occupancy or use by Tenant or any Tenant Parties, whether or not Landlord has consented to the same, increase the cost of Landlord’s insurance, Tenant will pay the full cost of any such
increase along with Additional Rent. A schedule issued by the organization computing the insurance rate shall be conclusive evidence of the cost of such increase in premium. If any of Landlord’s insurance is (or is threatened to be) cancelled
or the coverage thereunder reduced in any way because of any ad or acts, occupancy or use by Tenant or any Tenant Parties, Landlord may terminate this Lease and/or may enter upon the Premises at Tenant’s sole cost and expense and without any
liability to Tenant, and attempt to remedy such condition. All costs incurred by Landlord in performing any such remedial action shall be repaid by Tenant to Landlord within thirty (30) days after written demand, together with an administrative fee
equal to ten percent (10%) of such costs. 
  
 16.    NO SUBROGATION 
  
 All insurance policies which either party obtains, or is required to obtain hereunder, affecting the Premises shall include, if available from each party’s respective insurer upon commercially reasonable terms
and prices, a clause or endorsement denying the insurer any rights of subrogation against the other party. Landlord and Tenant waive any rights or recovery against the other for any actually insured injury or loss. 
  
 17.    DAMAGE OR
DESTRUCTION 
  
 If the Premises or any part
thereof is damaged by fire or other casualty, Tenant will promptly notify Landlord. 
  
 17.1    Cancellation of Lease; Restoration of Building. 
  
 If the Building or the premises or any significant portion of the Common Areas is damaged by fire or other casualty to the extent that, in Landlord’s
sole and absolute opinion, substantial alteration or reconstruction is required, or if any Mortgagee of a Mortgage requires that the insurance proceeds payable as a result of the fire or other casualty be applied against the indebtedness secured by
the Mortgage, Landlord may terminate this Lease by notifying Tenant within sixty (60) days after the later of the date the damage occurs or the date Landlord is so notified by its Mortgagee, in which event the Rent under this Lease will be equitably
abated as of the date of the fire or other casualty to the extent such damage materially impairs Tenant’s business operations at the Premises. If this Lease is not terminated, then within seventy- five (75) days after the fire or other
casualty, or such greater period as may be reasonably necessary, Landlord will commence to repair and restore the Premises and any portion of the Building and Common Areas acquired for access to the Premises, and will diligently complete the same,
but Landlord shall not be required (a) to expend more for such 
  

 17 









 repair of the Premises than the insurance proceeds in Landlord’s possession (or to be disbursed to Landlord pursuant
to the Mortgage) that exceed the proceeds retained (or required to be retained) by Mortgagee pursuant to its Mortgage and that are reasonably allocable to the Premises, or (b) to rebuild, repair or replace any of Tenant’s furniture,
furnishings, fixtures or equipment removable by Tenant under the provisions of this Lease or which Tenant has insured or is required to insure under the provisions of this Lease. If the Premises (or access thereto) is damaged by fire or other
casualty so as to unreasonably interfere with Tenant’s use and enjoyment of the Premises for Tenant’s normal business operations and Landlord reasonably determines that it will be unable to repair that portion of the Premises (or access
thereto) for which Landlord is responsible hereunder within two hundred seventy (270) days after such fire or other casualty, then Landlord shall deliver written notice to Tenant within sixty (60) days after such fire or other casualty informing
Tenant of Landlord’s inability to so repair the Premises (or access thereto) within said two hundred seventy (270) day period and Tenant shall have ten (10) days from the date of such notice during which to terminate this Lease by delivering to
Landlord written notice of Tenant’s desire to so terminate the Lease. If Tenant does not timely elect to so terminate this Lease, this Lease shall remain in full force and effect. 
  
 17.2    Casualty Loss During Last Year of Lease 
  
 If the Premises or the Building is damaged by fire or other casualty during
the last six (6) months of the Term, whether or not the damage requires substantial repair and reconstruction, either Tenant or Landlord may cancel this Lease as of the date of the tire or casualty by notice to the other within thirty (30) days
thereafter. 
  
 17.3    Abatement of
Rent 
  
 In the event of any damage described in this
Section 17, Base Rent shall be equitably abated in proportion to the extent that Tenant’s business operations at the Premises are impaired, such abatement to commence as of the date such damage occurs and will continue during the period of such
repairs. Except as expressly provided to the contrary in this Lease, this Lease will not terminate, and Tenant will not be entitled to damages or to any abatement of Rent, as a result of a fire or other casualty, repair or restoration. The
provisions of California Civil Code Sections 1932(2) and 1933(4) which permit termination of a lease upon destruction of Premises, and any other present or future statute that may so permit, are hereby waived by Tenant. 
  
 18.    CONDEMNATION 
  
 If all or substantially all of the Building or of the Premises or of the
parking areas in the Common Areas is taken for any public or quasi-public use under any governmental law, ordinance or regulation or by right of eminent domain or is sold to the condemning authority in lien of condemnation, then this Lease will
terminate on the earlier of the date title thereto passes to the condemning authority or when physical possession is taken by the condemning authority. If a lesser but material portion of the Building or Common Areas is thus taken or sold (whether
or not the Premises are affected thereby), then either Tenant (if the taking renders the Building and the Premises unsuitable for Tenant’s continued use of the Premises) or Landlord may terminate this 
  

 18 









 
Lease by notice to the other within sixty (60) days after the taking or sale, in which event this Lease will terminate on the earlier of the date title
thereto passes to the condemning authority or when physical possession of the applicable portion of the Building, the Common Areas or the Premises is taken by the condemning authority. If this Lease is not terminated pursuant to the foregoing and a
portion of the Premises has been taken or sold, the Base Rent and Tenant’s Share shall be adjusted according to the Rentable Area of the Premises remaining after such taking or sale, and Landlord, at its sole expense, will restore the affected
portion of the Building to substantially its former condition as far as feasible, but not beyond the work done by Landlord in originally constructing the affected portion of the Building and installing tenant improvements in the Premises. However,
Landlord shall not be required to expend more for any restoration of the Premises than the Premises’ allocable share of the net compensation or damages received by Landlord for the part of the Building taken and which compensation or damages
have been or will be released to landlord by Mortgagee. Landlord will be entitled to receive all of the compensation awarded upon a taking of any part or all of the Development, including, without limitation, any award for any unexpired term of this
Lease and Tenant hereby assigns such compensation so awarded to Landlord. Notwithstanding the foregoing, Tenant may seek an award in separate proceedings for its personal property, trade fixtures, moving expenses and good will. 
  
 In the event of a taking or sale of the Premises or any part thereof for
temporary use, this Lease shall remain unaffected and Rent shall not abate, and Tenant shall be entitled to such portion or portions of any award made for such use with respect to the period of the taking which is within the Term, provided that, if
such taking shall remain in force at the expiration or earlier termination of this Lease, Tenant shall then pay to Landlord a sum equal to the reasonable cost of performing Tenant’s obligations with respect to surrender of the Premises.

  
 To the extent that it is inconsistent with the provisions of
this Section 18, each party hereto hereby waives the provisions of Section 1265.130 of the California Code of Civil Procedure allowing either party to petition a court to terminate this Lease in the event of a partial taking of the Premises.

  
 19.    DEFAULTS AND
REMEDIES 
  
 19.1    Events of Default 
  
 The occurrence of any one or more of the following events shall constitute a default hereunder by Tenant: 
  
 (a)    Tenant fails to make a payment within five (5) days after written notice that such payment is due hereunder; provided, however,
that Landlord shall not be required to provide such notice more than twice during the Term with respect to Base Rent or Additional Rent, the third such non-payment constituting default without requirement of notice; or 
  
 (b)    Tenant attempts any Assignment (as defined in
Section 20) except as expressly permitted pursuant to Section 20; or 
  

 19 









 (c)    Tenant fails to comply with any other obligation under this Lease and does not
cure such failure as soon as reasonably practicable and in any event within twenty (20) days after written notice; 
  
 provided, however, if such failure cannot be cured during such twenty (20) day period, Tenant shall not be in default hereunder so long as Tenant commences to cure such
failure within that twenty (20) day period and thereafter diligently completes such cure; or 
  
 (d)    Tenant or any Guarantor becomes insolvent, makes a transfer in fraud of creditors or an assignment for the benefit of creditors, admits in writing its inability to pay its debts as they
become due, or files a petition under any Section or Chapter of the United States Bankruptcy Code or any similar law or statute; or an order for relief is entered with respect to Tenant or any Guarantor in any bankruptcy, reorganization or
insolvency proceedings; or a pleading seeking such an order is not discharged or denied, within sixty (60) days after its filing; or any action is taken at the corporate, partnership or company level by Tenant or any Guarantor to authorize any of
the foregoing actions on behalf of Tenant or any Guarantor; or a receiver or trustee is appointed for all or substantially all of the assets of Tenant or any Guarantor or of the Premises or any of Tenant’s property located thereon in any
proceedings brought by Tenant or any Guarantor, or any receiver or trustee is appointed in any proceeding brought against Tenant or any Guarantor and not discharged within sixty (60) days after appointment or Tenant or any Guarantor does not contest
such appointment; or any part of Tenant’s estate under this Lease is taken by process of law in any action against Tenant; or 
  
 (e)    Tenant abandons the Premises; or 
  
 (f)    Three (3) times within a year, Tenant fails to fulfill a monetary obligation or a material non-monetary obligation under this
Lease but thereafter cures such failure within the time provided. 
  
 Any notice specified above shall serve as, and not be in addition to, any notice required under California Code of Civil Procedure Section 1161 or otherwise regarding unlawful detainer actions. 
  
 19.2    Remedies 
  
 (a)    Upon an event of default, Landlord shall have the
immediate option to terminate this Lease and all rights of Tenant hereunder by-giving written notice to Tenant of such termination. If and when this Lease is so terminated, all rights of Tenant and those claiming under it will terminate and Landlord
may immediately recover from Tenant: 
  
 (i)    The worth at the time of award of any unpaid Rent which had been earned at the time of such termination; plus 
  
 (ii)    The worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination entail
the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 
  

 20 









 (iii)    The worth at the time of award of the amount by which the unpaid Rent for
the balance of the term after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided; plus 
  
 (iv)    Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to
perform Tenant’s obligations under this Lease or which in the ordinary course of things would be likely to result therefrom. 
  
 As used in Subsections (i) and (ii) above, the “worth at the time of award” is computed by allowing interest at the maximum rate permitted by
law. As used in Subsection (iii) above, the “worth at the time of award” is computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%). 
  
 (b)    Pursuant to California Civil Code Section 1951.4,
Landlord shall have the right to 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 Tenant’s rights to possession of the Premises and Landlord shall have
the right to collect Rent when due. Until this Lease is so terminated, Landlord may, on Tenant’s behalf, at Tenants sole cost and expense and in Landlord’s sole discretion, sublet any of the Premises (and, on expiration or earlier
termination of the sublease, may re-sublet) for all or part of the remainder of the Term, on whatever terms and conditions Landlord in its sole and absolute discretion deems advisable. Against the Rent and sums due from Tenant to Landlord during the
remainder of the Term, credit will be given Tenant in the net amount of Rent received from the new tenant but only after deduction by Landlord for (a) the costs incurred by Landlord in reletting the Premises (including, without limitation, repair
and remodeling costs, brokerage fees, legal fees and the like), and (b) all accrued scams, plus interest and late charges, under the terms of this Lease. 
  
 (c)    Upon an event of default or when Tenant is no longer entitled to possession, Landlord may enter the Premises and dispose of
Tenant’s property in accordance with law, and may perform Tenant’s obligations hereunder on Tenant’s behalf, Tenant will reimburse Landlord immediately on demand for Landlord’s attorneys’ fees and other expenses in doing so.
This Section 19.2(c) shall survive expiration or earlier termination of this Lease. 
  
 19.3    Continuing Liability 
  
 No repossession, re-entering or reletting of file Premises or any part thereof by Landlord shall relieve Tenant or any Guarantor of its liabilities and obligations under this Lease. 
  
 19.4    Remedies Cumulative 
  
 All rights and remedies of Landlord under this Lease will be non-exclusive of
and in addition to any other remedies available to Landlord at law or in equity. 
  

 21 









 19.5    No Waiver 
  
 Either party’s failure to insist on strict compliance with any terms
hereof or to exercise any right or remedy, does not waive the same. Waiver of any agreement regarding any breach does not affect any subsequent or other breach, unless so stated. A receipt by Landlord of any Rent with knowledge of the breach of any
covenant or agreement contained in this Lease shall not be a waiver of the breach, and no waiver by either party of any violation or provision of this Lease shall be effective unless expressed in writing and signed by such party. Payment by Tenant
or receipt by Landlord of a lesser amount than due under this Lease may be applied to such of Tenant’s obligations as Landlord elects. No endorsement or statement on any check, and no accompanying letter, shall make the same an accord and
satisfaction, and Landlord may accept any check or payment without prejudice to Landlord’s right to recover the balance of the Rent or pursue any other remedy provided in this Lease. 
  
 20.    ASSIGNMENT OR SUBLEASE 
  
 20.1    Notification 
  
 If Tenant intends to assign, transfer, or encumber this Lease or any estate
or interest herein, or permit the same too occur, or sublet or grant any right of occupancy for any part of the Premises or permit such occupancy by any other parties other than Tenant and any Tenant Parties, or modify or terminate any agreement for
any of the foregoing (the foregoing collectively referred to as an “Assignment,” and the other party thereto the “Assignee”), Tenant shall give Landlord written notice of such intent. Tenant’s notice shall be accompanied by
an exact copy of the proposed agreements between Tenant and the proposed Assignee. Tenant shall provide landlord with (a) any additional information or documents reasonably requested by Landlord within ten (10) days after receiving Tenant’s
notice, and (b) an opportunity to meet and interview the proposed Assignee, if requested. 
  
 20.2    Landlord Approval 
  
 Landlord shall then have a period of twenty (20) days following such Interview and receipt of such additional information (or thirty (30) days from the date of Tenant’s original notice if Landlord does not
request additional information or an interview) within which to notify Tenant in writing that Landlord elects, in its sole and absolute discretion, either (a) to terminate this Lease as to the space so affected as of the date so specified by Tenant,
in which event Tenant will be relieved of all further obligations hereunder as to such space arising from and after such termination except for those obligations which by their terms survive termination or earlier expiration of this Lease, or (b) to
permit the Assignment, subject, however, to prior written approval of the proposed Assignee by Landlord, such consent not to be unreasonably withheld so long as (i) the use of the Premises by such Assignee would be in accordance with Section 7.1
hereof (ii) the proposed Assignee is of sound financial condition as determined by Landlord in its good faith discretion, (iii) the Assignee would not cause the violation of any covenant or agreement of Landlord to any third party or would permit
any other tenant to terminate its lease, and (iv) the Assignee does not then lease or occupy any other space in the Development. If Landlord fails to notify Tenant in writing of its election within said period, Landlord shall be deemed to have
waived option (a) above, but written approval by Landlord 
  

 22 









 
of the proposed Assignee shall nonetheless be required in accordance with (b) above. Failure by Landlord to approve a proposed Assignee shall not cause a
termination of this Lease. If Tenant’s obligations under this Lease have been guaranteed by one or more Guarantors, then an Assignment, and Landlord’s consent thereto, shall not be effective unless the Guarantors give their written consent
to such Assignment and the terms thereof and explicitly agree in writing that the Guaranty shall remain in full force and effect notwithstanding such Assignment. 
  
 20.3    Allocation of Excess Rent 
  
 Any rent or other consideration realized by Tenant under any Assignment in
excess of the Rent payable hereunder, after amortization of the reasonable cost of the tenant improvements for which Tenant has paid and after amortization of the reasonable Assignment costs, shall be divided and paid as follows: (a) so long as
after such Assignment, the original Tenant named herein shall occupy not less than seventy-five percent (75%) of the Rentable Area of the premises, twenty-five percent (25%) to Tenant and seventy-five percent (75%) to Landlord; and (b) in all other
cases, ten percent (10%) to Tenant and ninety percent (90%) to Landlord. 
  
 20.4    Fair Market Rent 
  
 In any subletting undertaken by Tenant, Tenant shall diligently seek to obtain not less than Fair Market Rent for the space so sublet. In any assignment of this Lease in whole or In part; Tenant shall seek to obtain
from the assignee consideration reflecting a value of not less than Fair Market Rent for the space subjected to such assignment. Tenant shall provide Landlord, upon Landlord’s demand, true and correct executed copies of the documents
constituting such Assignment and any amendments thereof during the Term. 
  
 20.5    No Release from Liability 
  
 No Assignment by Tenant shall relieve Tenant or any Guarantor of any obligation under this Lease or any Guaranty. Any Assignment that conflicts with the
provisions hereof shall be void. No consent by Landlord to any Assignment shall constitute a consent to any other Assignment nor shall it constitute a waiver of any of the provisions of this Section 20 as they apply to any such fixture sublettings
or assignments. 
  
 20.6    Compliance
with Laws 
  
 Any improvements, additions, or alterations
to the Development that are required by any law, ordinance, rule or regulation, or are deemed necessary or appropriate by Landlord as a result of any Assignment hereunder, shall be installed and provided by Tenant or the Assignee without cost or
expense to Landlord. 
  
 20.7    Reimbursement of Costs 
  
 Landlord may lire outside consultants to review all Assignment documents and information. Tenant shall reimburse Landlord for the reasonable cost thereof, including reasonable attorneys’ 
  

 23 









 
fees, immediately on demand, but in no event shall Tenant be obligated to pay to Landlord more than One Thousand Five Hundred Dollars ($1,500.00).

  
 20.8    Negotiation with Assignee

  
 Without liability to Tenant, Landlord shall have the
right to offer and to lease space in the Development; or in any other property, to any party, including without limitation parties with whom Tenant is negotiating, or with whom Tenant desires to negotiate, concerning assignment or subletting the
premises, or any portion thereof. 
  
 20.9    Change of Control; Affiliates. 
  
 “Assignment” within the meaning of this Section 20 includes any change in control of Tenant or any Guarantor, or any sale of more than half the assets of Tenant or any Guarantor outside the ordinary course
of business. Tenant shall notify Landlord of any such change in control or sale prior to its consummation, and concurrently shall submit current financial statements applicable thereto, all subject to Landlord’s reasonable consent and
Landlord’s other rights under this Section 20, as in the case of any other Assignment. 
  
 Notwithstanding the foregoing, Landlord agrees that Tenant may enter into an Assignment, without Landlord’s consent, with any entity which controls, is controlled by or is under common control with Tenant, or
with any entity resulting from a merger or consolidation with Tenant, or with any person or entity which acquires all the assets of Tenant as a going concern in the business that is being conducted on the Premises, provided that, before such
Assignment shall be effective, (a) the Assignee shall assume in writing, in full, the obligations of Tenant under this Lease, (b) any Guarantor shall explicitly agree in writing that any Guaranty shall remain in full force and effect notwithstanding
such Assignment and (c) Landlord shall be given written notice of such assignment and assumption. Any such Assignment shall not, in any way, affect or limit the liability of Tenant or any Guarantor under the terms of this Lease or any Guaranty, even
if after such Assignment the terms of this Lease are materially changed or altered without the consent of Tenant, the consent of whom shall not be necessary. As used in this Section 20.9, control (including, with correlative meanings, the terms
“controlled by” and “under common control with”) shall mean the possession, directly or indirectly, of the power to direct or cause the direction of management and policies, whether through the ownership of voting securities or
by contract or otherwise. 
  
 20.10    Conveyance by Landlord 
  
 Landlord may transfer, assign and convey all or any part of or interest in the Development or any of its rights under this Lease. If Landlord transfers, ass’s or conveys its rights under this Lease, it shall
thereby be released from any further obligations under this Lease, Landlord’s successors-in-interest shall be deemed to have assumed those obligations, and Tenant will attorn and look solely to Landlord’s successor-in-interest for
performance of those obligations. 
  

 24 









 21.    SUBORDINATION 
  
 This Lease and all rights of Tenant under this Lease are subject, and
subordinate to any of the following, and any modifications thereof; which may now or hereafter affect any portion of the Development: (a) any Mortgage, or any ground or underlying lease covering any part of the Development, provided that the
Mortgage holder or ground lessor shall agree that Tenant’s peaceable possession of the Premises will not be disturbed on account of such subordination so long as Tenant is not in default under this Lease and attorns to such Mortgage holder or
ground lessor, (b) any applicable laws, rules, statutes and ordinances of any governmental authority having jurisdiction, and (c) all utility easements and agreements. On sale by foreclosure of a Mortgage or sale at lieu of foreclosure, Tenant will
attorn to the purchaser if requested by such purchaser, and recognize the purchaser as the Landlord under this Lease. These provisions are self-operative and no further instrument is required to effect them; however, upon demand from time to time,
Tenant shall execute, acknowledge and deliver to Landlord any commercially reasonable instruments and certificates necessary or proper to evidence such subordination, and/or attornment or, if Landlord so elects, to render any of the foregoing
subordinate to this Lease or to any or all rights of Tenant hereunder. Tenant further waives duo provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise
adversely affect this Lease and the obligations of Tenant hereunder in the event of any such foreclosure proceeding or sale, and, agrees that this Lease shall not be affected in any way whatsoever by any such proceeding or sale unless the Mortgagee,
or the purchaser, shall declare otherwise. 
  
 22.    ESTOPPEL CERTIFICATE 
  
 Promptly upon no less than ten (10) days after Landlord’s prior written request, Tenant will from time to time execute and deliver to Landlord a certificate, substantially in the form attached hereto as Exhibit
D, certifying. (i) the date of commencement of this Lease; (ii) the fact that this Lease is unmodified (except as the certificate specifies) and in full force and effect; (iii) the date to which the sums payable under this Lease have been paid; (iv)
that there are no current defaults under this Lease by either Landlord or Tenant except as specified; and (v) such other matters as Landlord requests. This certification may be relied upon by any actual or prospective Mortgagee or purchaser of all
or part of the Development or any interest therein or in Landlord. Failure to so execute and deliver said certificate will be conclusive upon Tenant (i) that this Lease is in full force and effect, without modification except as may be represented
by Landlord, (ii) that there are no uncured defaults in Landlord’s performance, and (iii) that no more than one (1) month’s rental has been paid in advance; and Tenant irrevocably authorizes Landlord, as Tenant’s attorney-in-fact and
in Tenant’s name, to so execute and deliver said certificate. Landlord shall deliver to Tenant, from time to time, upon no less than ten (10) days after Tenant’s prior written request, a certificate in a form similar to that described
herein and reasonably acceptable to Landlord. 
  

 25 









 23.    INTENTIONALLY DELETED 
  
 24.    SURRENDER OF
PREMISES

 STANDARDS FOR UTILITIES AND SERVICES

  
 1. Elevators. Provide non-attended passenger
elevators to and from the floor(s) on which the Premises are located. Landlord may limit the number of elevators operating outside normal business hours. 
  
 2. HVAC. On Monday through Friday, except holidays, from 7:00 a.m. to 6:00 p.m., ventilate the Premises and furnish air conditioning or heating on
such days and hours, in temperatures and amounts which in Landlord’s good faith judgment are reasonably required for comfortable occupancy of the Premises under normal business operations. If Tenant requires air conditioning during other hours,
Landlord will furnish same through an access system provided to Tenant at the Premises, if available, or otherwise as specified in a written request of Tenant delivered to the Building management office before noon on the preceding business day. For
this service Tenant will pay Landlord, upon receipt of Landlord’s statement, the charge at an hourly rate determined by Landlord from time to time, which is currently $30.00 per hour. Tenant agrees that neither Tenant nor any Tenant Party shall
at any time enter mechanical installations or facilities of the Building or adjust, tamper with, touch or otherwise in any manner affect said installations or facilities. The cost of maintenance and service calls to adjust and regulate the air
conditioning system shall be charged to Tenant if the need for maintenance work results from either Tenant’s adjustment of room thermostats or Tenant’s failure to comply with Landlord’s rules governing the temperature within the
Premises. 
  
 3. Lighting. Furnish electric lighting for
all public areas and special service areas of the Building as Landlord determines in good faith to be reasonable and standard, including replacement of Building standard lights, bulbs and tubes. 
  
 4. Electrical Service. Subject to the limitation of this Paragraph 4,
furnish electrical service to the Premises, including providing and installing all Building standard replacement lighting tubes. If Tenant uses more electrical power than Landlord in good faith considers reasonable or normal for office use, Tenant
will pay Landlord on a monthly basis the cost of such excess power consumed by Tenant. Consumption will be determined, at Landlord’s election, either (a) by a survey performed by a reputable consultant selected by Landlord, or (b) through
separate meters or submeters installed, maintained and read by Landlord at Tenant’s cost. For purposes of this Paragraph 4 only, “month” and “monthly” shall mean any billing period used by the utility or other power provider
supplying electricity. All installations of electrical fixtures, appliances and equipment within the Premises shall be subject to Landlord’s prior approval, and if they affect the temperature or humidity otherwise maintained, Landlord may, at
Tenant’s sole cost and expense (to be paid within (30) days after delivery of written demand supported by invoices or other reasonably satisfactory evidence), install supplemental air conditioning units. Tenant’s use of electricity shall
never exceed Tenant’s share of the capacity of existing feeders to the Binding or of the risers, wiring

Purchaser’s or Lender’s interest in the Property. Notwithstanding anything contained herein to the contrary, Lender shall have absolutely no obligation to perform any of Landlord’s construction covenants under the Lease, provided that
if Lender shall not perform such covenants in the event of foreclosure or deed in lieu thereof and within a reasonable time following taking of possession by Lender, then Tenant shall have the right to terminate its obligations under the Lease and
to pursue any and all legal remedies it may have against Landlord and any third parties other than Lender.

 3. ATTORNMENT 
  
 Unless the Lease is terminated in accordance wide Paragraph 2, if the interests of the lessor under the Lease shall be
transferred by reason of the exercise of the power of sale contained in the Security Deed (if applicable) or by any foreclosure or other proceeding for enforcement of the Security Deed, or by deed in lieu of foreclosure or such other proceeding, or
if Lender takes possession of the Property pursuant to any provisions of the Security Deed or the Assignment of Leases, the lessee thereunder shall be bound to the Purchaser or Lender, as the case may be, under all of the terms, covenants and
conditions of the Lease for the balance of the term thereof and any extensions or renewals thereof which tray be effected in accordance with any option therefor in the Lease, with the same force and effect as if the Purchaser or Lender were the
lessor under the Lease, and Tenant, as lessee under the Lease, does hereby attorn to the Purchaser and Lender if it takes possession of the Property, as its lessor under the Lease. Such attornment shall be effective and self-operative without the
execution of any further instruments upon the succession by Purchaser to the interest of the lessor under the Lease or the taking of possession of the Property by Lender. Nevertheless, Tenant shall, from time to time, execute and deliver such
instruments evidencing such attornment as Purchaser or Lender may require. The respective rights and obligations of Purchaser, Lender and of the lessee under the Lease upon such attornment, to the extent of the then remaining balance of the term of
the Tease and any such extensions and renewals, shall be and are the same as now set forth in the Lease except as otherwise expressly provided in Paragraph 2. 
  

4. SUBORDINATION 
  
 Tenant hereby subordinates all of its right, title and interest as lessee under the Lease to the right, title and interest of Lender under the Security
Deed, and Tenant father agrees that the Lease now is and shall at all times continue to be subject and subordinate in each and every respect to the Security Deed (including, without limitation, the casualty and condemnation provisions of the Lease,
which are hereby specifically subordinated to the Security Deed) and to any and all increases, renewals, modifications, extensions, substitutions, replacements and/or consolidations of the Security Deed. 
  
 Tenant agrees that from and after the date that the Lender, its successors or
assigns, or a court appointed receiver or trustee or a bona fide third-party purchaser shall have obtained fee title to the property pursuant to a foreclosure action or sale, deed-in-lieu of foreclosure or similar proceeding incident to the Security
Deed, any provision in the Lease providing the Tenant with an option to purchase the Property or any part thereof, or with a right of first refusal to purchase the Property or any part thereof, shall be of no further force and effect and shall
automatically terminate as of such date and, notwithstanding any provision of this Agreement or the Lease to the contrary, no such provision shall be binding upon the Lender or its successors and assigns. Without limiting the generality of the
foregoing, no such provision shall apply to a sale of the Property or any portion thereof at foreclosure or incident to a deed-in-lieu of foreclosure or similar proceeding. 
  

 F-3

interest as lessor under the Lease is being duly assigned to Lender pursuant to the terms of the Security Deed and the Assignment of Leases, and that pursuant to the terms thereof all rental payments under the Lease shall continue to be paid to
Landlord in accordance with the terms of the Lease unless and until Tenant is otherwise notified in writing by Lender. Upon receipt of any such written notice from Lender, Tenant covenants and agrees to make payment of all rental payments then due
or to become due under the Lease directly to Lender or to Lender’s agent designated in such notice and to continue to do so until otherwise notified in writing by Lender. Landlord hereby irrevocably directs and authorizes Tenant to make rental
payments directly to Lender following receipt of such notice, and covenants and agrees that Tenant shall have the right to rely on such notice without any obligation to inquire as to whether any default exists under the Security Deed or the
Assignment of Leases or the indebtedness secured thereby, and notwithstanding any notice or claim of Landlord to the contrary, and that Landlord shall have no right or claim against Tenant for or by reason of any rental payments made by Tenant to
Lender following receipt of such roller; provided, however, Landlord does, not waive oil release any rights it may have against Lender. Tenant further acknowledges and agrees: (a) that under the provisions of the Security Deed and the Assignment of
Leases, the Lease cannot be canceled or amended (nor can Landlord accept any surrender of the Lease) or terminated (except in accordance with the terminated provisions in the Lease) nor can any consent be given by Landlord to the waiver or release
of Tenant from the performance or observance of, any obligation under the Lease, without, is each instance, the prior written consent of Lender, and without such consent no rent may be collected or accepted by Landlord more than one month in
advance; and (b) that the interest of Landlord as lessor under the Lease has been assigned to Lender for the purposes specified in the Security Deed and the Assignment of Leases, and Lender assumes no duty, liability or obligation under the Lease,
except only under the circumstances, terms and conditions specifically set forth in the Security Deed, the Assignment of Leases and this Agreement. 
  
 6. NOTICE OF DEFAULT BY LESSOR 
  
 Tenant, as lessee under the Lease, hereby covenants and agrees to give Lender
written notice properly specifying wherein the lessor under the Lease has failed to perform any of the covenants or obligations of the lessor under the Lease, simultaneously with the giving of any notice of such default to the lessor under the
provisions of the Lease. Tenant agrees that Lender shall have the right, but not the obligation, within thirty (30) days after receipt by Lender of such notice (or within such additional time as is reasonably required to correct any such default) to
correct or remedy, or cause to be corrected or remedied; each such default before the lessee under the Lease may take a any action under the Lease by reason of such default. Such notices to Lender shall be delivered in duplicate to:

 FIRST AMENDMENT TO LEASE 
  
 This First Amendment to Lease (“First Amendment”) is made and entered into as of the 25th day of October, 1999 by
and between GATEWAY CENTER, LLC, a California limited liability company (“Landlord”), and ELAN PHARMACEUTICALS, INC., a Delaware corporation (“Tenant”). 
  
 RECITALS: 
  
 A. HMS Office, L.P., a Delaware limited partnership (“Prior Landlord”), predecessor-in-interest to Landlord, and Tenant entered into that
certain Lease dated June 1, 1999 (the “Lease”), permitting to the lease of approximately 9,901 mutable square feet of space (the “Existing Premises”) known as Suites 950 and 980, and located on the ninth (9th) floor of the
building located at 651 Gateway Boulevard, South San Francisco, California (the “651 Building”). 
  
 B. Tenant desires to expand the Existing Premises to include approximately 18,820 rentable square, feet of space, which constitutes the entire eighth
(8th) floor of the building located at 601 Gateway Boulevard, South San Francisco, California (the “601 Building”) known as suite 800 (the “Expansion Premises”), and to make other modifications to the Lease, and in connection
therewith, Landlord and Tenant desire to amend the Lease as hereinafter provided. 
  
 AGREEMENT: 
  
 Now,
THEREFORE, in consideration of the foregoing Recitals and the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereby agree as follows:

  
 1. Premises. 
  
 1.1 Expansion Premises. Effective as of the
“Expansion Premises Commencement Date,” as that team is defined in Section 2 below. Tenant shall lease from Landlord and Landlord shall lease to Tenant the Expansion Premises. Consequently, effective upon the Expansion Premises
Commencement Date, the Existing Premises shall be increased to include the Expansion Premises. The Exiting Premises and the Expansion Premises may herein collectively be referred to as the “Premises.” Landlord and Tenant hereby agree that
the addition of the total Expansion Premises to the Existing Premises shall, increase the size of the “Premises,” as that term is defined in the Lease, to approximately 28,721 rentable square feet. 
  
 1.2 Right of First Offer. Landlord hereby grants to the Tenant
named in the Summary (the “Original Tenant”) a right of first offer with respect to available space located on the seventh (7th) and ninth (9th) floors of the 601 Building (the “First Offer Space”). Notwithstanding the foregoing,
such first offer right of Tenant shall be subordinate to all rights of which are set forth in leases of space in the Project as of the date hereof, including any renewal, extension or expansion rights set forth in such leases, regardless of whether
such renewal, extension or expansion rights are 








 executed strictly in accordance with their terms, or pursuant to a lease amendment or a new lease (collectively, the
“Superior Right Holders”) with respect to such First Offer Space. Tenant’s right of first offer shall be on the terms and conditions set forth in this Section 1.2. 
  
 1.2.1 Procedure for Offer. Tenant shall notify Landlord from time to time in the event Tenant is interested
in leasing First Offer Space (the “Interest Notice”). For the six (6) months immediately following Landlord’s receipt of an Interest Notice, Landlord shall promptly notify Tenant in the event First Offer Space or any portion thereof
becomes available for lease to third parties, provided that no Superior Right Holder wishes to lease such space (the “First Offer Notice”) and such first Offer Space is not then subject to negotiation of a lease proposal or lose document
with a prospective tenant. In the event no First Offer Space becomes available during the six (6) months following Landlord’s receipt of an Interest Notice, Tenant shall have the option to deliver another Interest Notice to Landlord. Pursuant
to such First Offer Notice, Landlord shall offer to lease to Tenant the then available First Offer Space. The First Offer Notice shall describe the space so offered to Tenant and shall set forth the “First Offer Rent,” as that term is
defined in Section 12.3 below, and the other economic teems upon which Landlord is willing to lease such space to Tenant. 
  
 1.2.2 Procedure for Acceptance. If Tenant wishes to exercise Tenant’s light of first offer with respect to the space described in the
First Offer Notice, then within five (5) business days of delivery of the First Offer Notice to Tenant, Tenant shall deliver notice to Landlord of Tenant’s intention to exercise its right of first offer with respect to the entire space
described in the First Offer Notice on the terms contained in such notice. If Tenant does not so notify Landlord within the five (5) business day period, then Landlord shall be free to lease the space described in the First Offer Notice to anyone to
whom Landlord desires on any terms Landlord desires. Notwithstanding anything to the contrary contained herein, Tenant must elect to exercise its right of first offer, if at all, with respect to all of the space offered by Landlord to Tenant at any
particular time, and Tenant may not elect to lease only a portion thereof. 
  
 1.2.3 First Offer Space Rent. The “Rent,” as that term is defined in Section 4.1, below, payable by Tenant for the First Offer Space (the “First Offer Rent”) shall be equal to rent
(including additional rant and considering any “base year” or “expense stop” applicable thereto); including all escalations, at which tenants, as of the “First Offer Commencement Date,” as that term defined in
Section 1.2.5, below, are leasing non-sublease, non-encumbered, non-equity space comparable in size, location and quality to the First Offer Space for a similar lease term, which comparable space is low in the Project, taking into
consideration the following concessions: (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space, (b) tenant improvements or allowances provided or to be provided for such comparable space,
taking into account and deducting the value of, the existing improvements in the First Offer Space, such value to be based upon the age, quality and layout of the improvements and the extent to which the same could be utilized by a general office
user, and (c) any period of rental abatement, if any, granted to tenants in comparable transactions in connection with the design, permitting and construction of tenant improvements in such comparable spaces. 
  

 -2- 









 1.2.4 Construction in First Offer Space. Tenant shall take the First Offer Space in its
“as is” condition, and the construction of improvements in the First Offer Space shall comply with the terms of Article 10 of the Lease. 
  
 1.2.5 Amendment to Lease. If Tenant timely exercises Tenant’s right to lease the First Offer Space as set forth herein, Landlord and
Tenant shall within fifteen (15) days thereafter execute a separate lease for such First Offer Space: upon the terms and conditions as set forth in the First Offer Notice and this Section 1.2. Tenant shall commence payment of Rent for the First
Offer Space, and the term of the First Offer Space shall commence upon the date of delivery of the First Offer Space to Tenant (the “First Offer Commencement Date”) and terminate on the date set forth in the First Offer Notice. 

 
 1.2.6 Termination of Right of First Offer. The rights
contained in this Section 1.2 be personal to the Original Tenant, and may only be exercised by the Original Tenant or a permitted Assignee pursuant to Article 20 of the Lease (and not any other assignee, sublessee or other transferee of the
Original Tenant’s interest in this Lease) if the Original Tenant or such permitted Assignee occupies the entire Premises. The right of first offer granted herein shall terminate as to particular First Offer Space upon the failure by Tenant to
exercise its right of first offer with respect to such First Offer Space as offered by Landlord. Tenant shall not have the right to lease First Offer Space, as provided in this Section 1.2, if, as of the date of the attempted exercise of any
right of first offer by Tenant, or as of the scheduled date of delivery of such First Offer Space to Tenant, Tenant is in default under this Lease or Tenant has previously been in default under this Lease more than once. 
  
 2. Term. 
  
 2.1 Initial Lease Term. The term of Tenants lease of the
Expansion Premises (the “Expansion Term”) shall commence on December 15, 1999 (the “Expansion Premises Commencement Date”), and shall expire, along with Tenants lease of the Existing Premises; on December 14, 2004, unless sooner
terminated as provided in the Lease, as hereby amended. 
  
 2.2
Option Term 
  
 2.2.1 Option Right. Landlord
hereby grants the Original Tenant one (1) option to extend the Lease Term for a period of five (5) years (the “Option Term”), which option shall be exercisable only by written notice delivered by Tenant to Landlord as provided below,
provided that, as of the date of delivery of such notice, Tenant is not in default under this Lease. Upon the proper exercise of such option to extend, and provided that, at Landlord’s option, as of the end of the initial Lease Term, Tenant is
not in default under this Lease, the Lease Term, as it applies to the Premises, shall be extended for a period of five (5) years. The rights contained in this Section 2.2 shall be personal to the Original Tenant or a permitted Assignee pursuant to
Article 20 of the Lease, and may only be exercised by the Original Tenant or such permitted assignee (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if the Original Tenant occupies the
entire Premises. 
  

 -3- 









 2.2.2    Option Rent.    The Rent payable by
Tenant ding the Option Term (the “Option Rent”) shall be equal to the rent (including additional rent and considering any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants as
of the commencement of the Option Term, are leasing non-sublease, non-encumbered space comparable in size, location and quality to the Premises for a term of five (5) years, which comparable space is located in the Building, at the building located
at 601 Gateway Boulevard, or within a five (5) mile radius of the Building, taking into consideration the following concessions: (a) rental abatement concessions, if nay, being granted such tenants in connection with such comparable spaces and (b)
tenant improvements or allowances provided or to be provided for such comparable space, taking into account, and deducting the value of, the existing improvements in the Premises, such value to be based upon the age, quality and layout of the
improvements and the extent to which the same could be utilized by Tenant based upon the fact that the precise tenant improvements existing in the Premises are specifically suitable to Tenant. 
  
 2.2.3    Exercise of
Options.    The option contained in this Section 2.2 shall be exercised by Tempt, if at all, and only in the following warmer: (i) Tenant shall deliver written notice to Landlord not more than eight (8) months nor

to Tenant not less than five (5) months prior to the expiration of the initial Lease Term, setting forth the Option Rent; and (iii) if Tenant wishes to exercise such option, Tenant shall, on or before the earlier of (A) the date occurring four (4)
months prior to the expiration of the initial Least Term, and (B) the date occurring thirty (30) days after Tenant’s receipt of the Option Rent Notice, exercise the option by delivering written notice thereof to Landlord and upon, and
concurrent with, such exercise, Tenant may, at its option, object to the Option Rent contained in the Option Rent Notice, in which case the parties shall follow the procedure, and the Option Rent shall be as set forth in Section 2.2.4 below.

  
 2.2.4    Determination of Option
Rent.    In the event Tenant timely objects to the Option Rent, Landlord and Tenant shall attempt to agree upon the Option Rent using their best good faith efforts. If Landlord and Tenant fail to reach agreement within
ten (10) business days following Tenant’s objection to the Option Rent (the “Outside Agreement Date”), then each party shall make a separate determination of the Option Rent within five (5) business days after the Outside Agreement
Date, end such determinations shall be submitted to arbitration in accordance with Sections 2.2.4.1 through 2.2.4.7 below. 
  
 2.2.4.1    Landlord and Tenant shall each appoint one (1) arbitrator who shall be a real estate broker who shall have been active
over the five (5) year period ending on the date of such, appointment in the leasing of commercial high-rise properties in South San Francisco, California. The determination of the arbitrators shall be limited solely to the issue of whether
Landlord’s or Tenant’s submitted Option Rent is the closest to the actual Option Rent as determined by the arbitrators, taking into account the requirements of Section 2.2.2 of this Lease. Each such arbitrator shall be appointed within
fifteen (15) days after the Outside Agreement Date. 
  

 -4- 









 2.2.4.2    The two (2) arbitrators so appointed shall within ten (10) days of the
date of the appointment of the last appointed arbitrator agree upon and appoint a third arbitrator who shall be qualified under the same criteria set forth herein above for qualification of the initial two (2) arbitrators. 
  
 2.2.4.3    The three (3) arbitrators shall within thirty
(30) days of the appointment of the third arbitrator reach a decision as to whether the parties shall use Landlord’s or Tenant’s submitted Option Rent and shall notify Landlord and Tenant thereof. 
  
 2.2.4.4    The decision of the majority of the three (3)
arbitrators shall be binding upon Landlord and Tenant.

Month Index,” as that term is defined in Section 4(A)(1) below, occurring prior to such CPI Adjustment Date and the denominator of which is either (I) for the Initial CPI Adjustment Date, the “Base Month Index,” as that term is
defined in Section 4(A)(2) below, or (II) for all subsequent CPI Adjustment Dates, the Adjustment Month Index used as the numerator for the previous CPI Adjustment Date;

 -6- 









 
only, if the Expansion Premises Commencement Date were to occur on December 1, 1999, then the Initial Adjustment Date would occur on December 1, 2000, the

 3)  “Index” shall mean the Consumer Price Index for all
Urban Consumers for the San Francisco area (base year 1982 1984 100), published by the United States Department of Labor. Bureau of Labor Statistics. If the base of the Index changes from the 1982 -84 base (100), the Index shall, thereafter, be
adjusted to the 1982-84 base 100 before the computation indicated above is made. If the Index cannot be converted to the 1982-84 base or if the Index is otherwise revised, the adjustment under this section shall be made with the use of such
conversion factor, formula or table for converting the Index as may be published by the Bureau of Labor Statistics. If the Index is at any time no longer published, a comparable index generally accepted and employed by the real estate profession, as
determined by Landlord in Landlord’s sole but reasonable discretion, shall be used.

 SECTION 2 
 TERM 
  
 The term of this lease of the Storage Area to Tenant shall commence on

have the right to terminate this Agreement at any time, upon not less than thirty (30) days’ prior written notice to the other party. In any event, this Agreement shall terminate upon the expiration or any earlier termination of the term of the

rental value of such space. Landlord shall provide to the Storage Area lighting adequate for storage use; no other services or utilities (including, without limitation, heating, cooling or cleaning) shall be provided to the Storage Area. 

 
 SECTION 4 
 INDEMNIFICATION 
  
 Tenant agrees and acknowledges that its use of the Storage Area is at its sole risk, and Tenant hereby waives and absolves Landlord from any and all cost,
loss, damage, expense, and liability, whether foreseeable or not, from any cause whatsoever, that Tenant may suffer to its personal property located anywhere in the Storage Area or that it or its agents, employees, principals, invitees, and
licensees may suffer as a direct or indirect consequence of Tenant’s lease of or use of the Storage Area or access areas to the Storage Area or for any other reason arising from or related to this Agreement. In addition, Tenant hereby agrees to

 SECTION 5

 -2- 









 hereof. Landlord shall have the right to require any or all items stored in the Storage Area to be stored on pallets.
Tenant agrees to use the Storage Area solely for storage purposes of dry goods and not as office space. Tenant agrees that Landlord and its agents may enter and inspect the Storage Area and any goods stored therein at any time upon giving reasonable
notice to Tenant. Tenant accepts the Storage Area in its “as is,” “with all faults,” “without any warranties or representations” condition, and shall alter (with Landlord’s prior approval, which approval shall not
be unreasonably withheld or delayed), maintain and repair the Storage Area at its sole cost and expense. Tenant acknowledges that, as of the date of this Agreement, the California Fore Code requires an eighteen inch (18”) vertical clearance
between sprinkler heads and all items stored in the Storage Area, and, without limiting any other obligation of Tenant hereunder or under the Lease, Tenant hereby agrees to comply with this requirement, as it may be modified from time to time.

  
 SECTION 6 
 DEFAULTS 
  
 Breach of any of its covenants hereunder by Tenant shall, at the option of Landlord, also constitute a default under the Lease. A default under the Lease
by Tenant shall, at the option of Landlord, immediately constitute a default hereunder.

 Any nonce required or permitted to be given hereunder by Tenant or Landlord shall be given pursuant to the terms of
Section/Article      of the Lease, except that notices to Landlord shall be addressed to Gateway Center LLC, the address of which is c/o Boston Properties L. P., Suite One—Lobby Level, Four Embarcadero Center, San
Francisco, CA 94111. 
  
 SECTION 8 
 RELOCATION OF STORAGE AREA 
  
 Landlord reserves the right, upon not less than thirty (30) days’ prior written notice to Tenant, to substitute for the Storage Area comparable
storage area within the Building having substantially equivalent usable area as the Storage Area, provided that Landlord shall pay all expenses reasonably incurred in moving Tenant’s property to such new location; and upon the expiration of
such 30-day written notice, the new storage area shall be deemed to be the Storage Area covered by this Agreement. If the new storage area is less than the Storage Area as it existed before the substitution, monthly Storage Rent shall be reduced by
a sum computed by multiplying the monthly Storage Rent by a fraction, the numerator of which shall be total number of usable square feet in the new storage area and the denominator of which shall be the total number of usable square feet in the
Storage Area before substitution. 
  

 -3- 









 SECTION 9 
 INCORPORATION OF LEASE PROVISIONS 
  
 All applicable provisions of the Lease shall be deemed to apply to the Storage Area as though Landlord were the landlord under the Lease and the Storage Area were part of the Premises, and as though the, Storage Rent
were part of base rent, and such provisions are hereby incorporated into this Agreement by this reference as though fully set forth herein. In no event shall any damage to or destruction of the Storage Area cause a termination of the Lease under
Section/Article              thereof. In the event of any conflict between the provisions of this Agreement and the provisions of the Lease, the terms of this Agreement shall govern.

  
 IN WITNESS WHEREOF, the parties have entered into this
Agreement as of the date first written above.

 R E C I T A L S: 
  
 A. Reference is hereby made to that certain Office Lease dated June 1, 1999,

 B. Pursuant to the terms of Section 20 of the Office Lease, Tenant has requested Landlord’s consent to that certain Sublease dated March 21, 2003,
between Tenant and Subtenant (the “Sublease”), with respect to a subletting by Subtenant of a portion of the Premises known as Suite 980 located on the ninth (9th) floor of the Building, as more particularly described in the Sublease (the
“Sublet Premises”). A copy of the Sublease is attached hereto as Exhibit A. Landlord is willing to consent to the Sublease on the terms and conditions contained herein. 
  
 C. All defined terms not otherwise expressly defined herein shall have the respective meanings given in the Lease.

  
 A G R E E M E N T: 
  
 1. Landlord’s Consent. Landlord hereby consents to the Sublease;
provided however, notwithstanding anything contained in the Sublease to the contrary, such consent is granted by Landlord only upon the terms and conditions set forth in this Agreement. The Sublease is subject and subordinate to the Lease. Landlord
shall not be bound by any of the terms, covenants, conditions, provisions or agreements of the Sublease. 
  
 2. Non-Release of Tenant; Further Transfers. Neither the Sublease nor this consent thereto shall release or discharge Tenant from any liability,
whether past, present or future, under the Lease or alter the primary liability of Tenant to pay the rent and perform and comply with all of the obligations of Tenant to be performed under the Lease: (including the payment of all bills rendered by
Landlord for charges incurred by Subtenant for services and materials supplied to the Sublet Premises). Neither the Sublease nor this consent thereto shall be construed as a waiver of Landlord’s right to consent to any further subletting either
by Tenant or by Subtenant or to any assignment by Tenant of the Lease or assignment by Subtenant of the Sublease, or as a consent to any portion of the Sublet Premises being used or occupied by any other party. Landlord may consent to subsequent
sublettings and assignments of the Lease or the Sublease or any amendments or modifications thereto without notifying Tenant nor anyone else liable under the Lease and without 
  

 -1- 









 obtaining their consent. No such action by Landlord shall relieve such persons from any liability to Landlord or
otherwise with regard to the Sublet Premises. 
  
 3.
Relationship With Landlord. Tenant hereby assigns and transfers to Landlord all of Tenant’s interest in the Sublease and all rentals and income arising therefrom, subject to the terms of this Section 3. If an Event of Default (as defined

terminate the Sublease; (ii) to keep the Lease in full force and effect (provided that the Lease has not been terminated by Landlord or otherwise), and to receive and collect (or to continue to receive and collect, as the case may be) directly from
Subtenant all rent and other sums owing and to be owed under the Sublease, as further set forth in Section 3.1, below, it being understood that, notwithstanding anything to the contrary contained in the Lease, and in addition to Landlord’s
other rights and remedies contained in the Lease, upon the occurrence of an Event of Default under the Lease, Landlord shall have the remedy described in California Civil Code Section 1951.4 (Landlord may continue lease in effect after Tenant’s
breach and abandonment and recover rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations); or (iii) to terminate the Lease and to succeed to Tenant’s interest in the Sublease and cause
Subtenant to attorn to Landlord, as further set forth in Section 3.2, below.

and/or other sums due or to become due under the Sublease, and Tenant hereby agrees that Subtenant shall have the right to rely upon any such written notice from Landlord, and that Subtenant shall pay any such rents and/or other sums directly to
Landlord without any obligation or right of inquiry and notwithstanding any notice from or claim of Tenant to the contrary. Until such time as Landlord shall deliver written notice to Tenant and Subtenant in accordance with the foregoing sentence,
Landlord agrees that Tenant may receive, collect and enjoy the rents accruing under the Sublease. Landlord shall not, by reason of the Sublease, nor by reason of the collection of any rents or any other sums from Subtenant pursuant to this Section
3.1, be deemed liable to Subtenant for any failure of Tenant to perform and comply with any obligation of Tenant. Tenant shall not have any right or claim against Subtenant for any such rents or other sums so paid by Subtenant to Landlord. Neither
Landlord’s acceptance of any payment on account of rent or any other sums from Subtenant (regardless of the circumstances therefor and whether or not any Event of Default has occurred under the lease) nor Landlord’s acceptance of
performance by Subtenant of any obligations of Tenant under the Lease shall in any manner whatsoever (i) be deemed an attornment by Landlord to Subtenant or by Subtenant to Landlord in the absence of a specific written agreement signed by Landlord
to such effect, (ii be deemed a waiver by Landlord of any provision of the Lease, or (iii) serve to release Tenant from any liability under the terms, covenants, conditions, provisions or agreements under the Lease. Notwithstanding the foregoing,
within thirty (30) days following collection by Landlord of any rents or other sums from Subtenant pursuant to this Section 3.1, Landlord shall credit the amount thereof 
  

 -2- 









 against Tenant’s rental obligations under the Lease (including any Sublease profit calculated pursuant to the
provisions of Section 20 of the Office Lease) next coming after the date of such credit. Notwithstanding anything to the contrary contained herein, in no event shall Landlord be liable to Tenant in any manner whatsoever or under any circumstances
whatsoever for any failure by Landlord to collect any rents or any other sums from Subtenant under the Sublease.

or any security deposit paid by Subtenant, (ii) be liable for any previous act or omission of Tenant under the Lease or for any other defaults of Tenant under the Sublease, (iii) be subject to any defenses or offsets previously accrued which
Subtenant may have against Tenant, or (iv) be bound by any changes or modifications made to the Sublease without the written consent of Landlord.

of any type payable by Subtenant to Tenant with regard to the Sublet Premises other than as disclosed in the Sublease.

fees) incurred by Landlord in resisting any claim for any such brokerage commission.
