This Sublease Agreement (this “Sublease”) is dated as of September 11, 2014, by and between Accesia, Inc., a Virginia corporation (hereinafter referred to as “Sublandlord”), and Atara Biotherapeutics, Inc., a Delaware corporation (hereinafter referred to as “Subtenant”).

All capitalized terms used but not defined herein shall have the meanings given to such terms in the Lease.

1.02 Subtenant has requested and proposed to Sublandlord, and Sublandlord has agreed, that Subtenant be permitted to sublease the Premises, as more particularly identified on Exhibit A attached hereto and incorporated by reference into this Sublease, on the mutual terms and conditions set forth in this Sublease.

NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Sublandlord and Subtenant hereby agree as follows:

(a) Sublandlord hereby subleases to Subtenant, and Subtenant hereby subleases from Sublandlord, the Premises for the period of time and otherwise on the terms and conditions set forth in this Sublease. Sublandlord and Subtenant hereby agree and stipulate that for all purposes of this Sublease, including but not limited to the calculation of Rent, the Premises shall be deemed to comprise seven thousand and thirty eight (7,038) square feet of Rentable Area.

(b) Subtenant shall have the exclusive right to utilize all existing filing cabinets, furniture, fixtures, cables, wiring, and equipment currently located within Premises which Sublandlord has left therein (collectively, “Sublandlord’s FF&E”) as set forth on Exhibit B hereto, at no cost during the Sublease Term (as defined below). Subtenant acknowledges and agrees that Sublandlord’s FF&E is owned by Sublandlord and is being provided solely for Subtenant’s use and enjoyment during the Sublease Term. Subtenant represents and warrants that it has examined Sublandlord’s FF&E and agrees to accept it in its then “as is” and “where-is” condition and that Sublandlord has no obligation to refinish, maintain, repair or replace any of Sublandlord’s FF&E. Sublandlord has not made and does not make any representations or warranties as to the condition, usability or any other matter or condition affecting Sublandlord’s FF&E and shall have no responsibility with respect thereto. Sublandlord and Subtenant acknowledge and agree that Subtenant will supply its own computers, servers, telephone equipment and printers. Subtenant shall purchase the

Sublandlord’s FF&E at the end of the Sublease Term at a cost of one dollar ($1.00) and agrees to remove all of Sublandlord’s FF&E from the Premises as required under Section 2.18 hereof. Notwithstanding anything to the contrary above, Subtenant hereby acknowledges and agrees that certain of the existing cabinets, furniture, fixtures, and equipment currently located within the conference room of the Premises are owned by the Landlord and shall not be subject to the rights granted to Subtenant or the obligations of Subtenant to remove such furniture, fixtures and equipment under this Section 2.01(b).

(c) Subtenant shall also be allowed to use any interior or exterior areas of the Building made available by Landlord from time to time for Subtenant’s use or for the use of all tenants (collectively, the “Common Areas”) on the terms and conditions set forth in the Lease.

(a) The term of this Sublease (the “Sublease Term”) shall commence on the the date that Landlord has issued its written consent to this Sublease (the “Commencement Date”), which consent Sublandlord shall use good faith commercially reasonable efforts to obtain from Landlord prior to September 15, 2014. Unless sooner terminated as provided in this Sublease, the Sublease Term shall run coterminous with the Lease and expire on January 31, 2017 (the “Expiration Date”).

(b) If for any reason Sublandlord cannot deliver possession of the Premises to Subtenant on or before September 15, 2014 as currently desired by the parties, Sublandlord shall not be subject to any liability therefor, nor shall Sublandlord be in default hereunder nor shall such failure affect the validity of this Sublease, and Subtenant agrees to accept possession of the Premises at such time as Sublandlord is able to deliver the same, which date shall then be deemed the Commencement Date provided that Landlord has issued its written consent to this Sublease. Notwithstanding the foregoing, in the event that the Commencement Date does not occur by October 31, 2014, then Subtenant shall be entitled by notice in writing to Sublandlord within ten (10) days thereafter to cancel this Sublease, in which event the parties shall be discharged from all obligations hereunder.

(a) Commencing on the Commencement Date and on the first (1st) day of each month thereafter and continuing for the first year of the Sublease Term, Subtenant shall pay to Sublandlord, for the use of Premises, annual “Base Rent” at a rate of Two Dollars and Seventeen Cents ($2.17) per square foot of Rentable Area, for a total monthly amount of Fifteen Thousand Two Hundred Seventy Two Dollars and Forty Six Cents ($15,272.46). Beginning on the first anniversary of the Commencement Date and continuing on each anniversary thereafter throughout the Sublease Term, the Base Rent shall increase annually at a rate equal to an additional ten cents ($0.10) per rentable square foot as follows: (i) Subtenant shall pay Two Dollars and Twenty Seven Cents ($2.27) per square foot of Rentable Area, for a total monthly amount of Fifteen Thousand Nine Hundred Seventy Six Dollars and Twenty Six Cents ($15,976.26), for the period beginning on the first anniversary of the Commencement Date up to and until the second anniversary of the Commencement Date; and (ii) Subtenant shall pay Two Dollars and Thirty Seven Cents ($2.37) per square foot of Rentable Area, for a total monthly

amount of Sixteen Thousand Six Hundred Eighty Dollars and Six Cents ($16,680.06), for the period beginning on the second anniversary of the Commencement Date up to and until the Expiration Date.

a. For purposes of this Section 2.03(b), the following terms shall have the following meanings:

“Base Operating Costs” shall have the meaning given to such term in the Lease; provided that the term “Base Year,” as used therein shall mean the 2015 calendar year.

“Base Year Costs” means Base Operating Costs and Base Taxes for the 2015 calendar year.

“Operating Costs” shall have the meaning given to such term in the Lease.

“Proportionate Share” shall mean 100% of the Sublandlord’s Proportionate Share under Section 1.13 of the Lease.

“Sublease Year” shall mean the calendar year, or portion thereof, following the Commencement Date and during the Sublease Term, the whole or any part of which period is included within the Sublease Term.

b. If the Operating Costs and Taxes for any Sublease Year, calculated on the basis of the greater of (i) actual Operating Costs and Taxes; or (ii) as if the Building were at least one hundred percent (100%) occupied and operational for the whole of such Sublease Year, are more than the applicable Base Year Costs for Base Operating Costs and Base Taxes as set forth in Section 2.03(a) above (which Base Year Costs shall be calculated separately for Operating Costs and Taxes), Subtenant shall pay to Sublandlord its Proportionate Share of any such increase in Operating Costs and/or Taxes, as the case may be, as “Additional Rent” as hereinafter provided.

c. If any Sublease Year of less than twelve (12) months is included within the Sublease Term, the amounts payable by Subtenant for such period shall be prorated on a per diem basis based on the actual number of days in the year.

d. Subtenant shall pay monthly installments of Subtenant’s Proportionate Share of any Additional Rent owed to Sublandlord under this Section 2.03 on the first day of each month, in amounts specified in good faith by Sublandlord from time to time (and based on the estimates received from

Landlord), which, by the end of each Sublease Year (or by the Expiration Date, if earlier), will total Sublandlord’s estimate of Subtenant’s Proportionate Share of any Additional Rent paid for such Sublease Year. As soon as is reasonably practicable after the end of each Sublease Year during which Subtenant paid any Additional Rent based on Sublandlord’s estimates as provided above, Sublandlord will furnish Subtenant with the Annual Statement Sublandlord receives from Landlord under Section 6.3(b) of the Lease. Subtenant acknowledges and agrees that the Additional Rent due each month is subject to change throughout the Sublease Term. The Additional Rent shall be adjusted pursuant to the procedure set forth in Section 6.3(c) of the Lease at the end of each Lease Year under the Lease, and Subtenant shall promptly pay its share of any Additional Rent owed or receive a credit or reimbursement for its share of any overage, as provided in Section 6.3(c) of the Lease.

(c) Base Rent, Additional Rent and all other amounts payable by Subtenant hereunder (collectively, “Rent”), shall be paid by Subtenant in United States legal tender, without any set-off or deduction whatsoever, to Sublandlord at the following address: Accesia, Inc. c/o The Phillips Organization, 3924 Cleveland Avenue NW, Canton, Ohio 44709, or to such other party or such other place as Sublandlord may from to time designate in writing to Subtenant.

(d) Base Rent for each month during the Sublease Term shall be due and payable in advance, on or before the first (1^st) day of each month, without demand and without any set-off or deduction whatsoever. If Base Rent, Additional Rent, or any other sums payable by Subtenant to Sublandlord hereunder are not paid by Subtenant when such payment is due, Subtenant shall pay Sublandlord interest and late charges on all overdue amounts as provided in Sections 33.8 and 33.9 of the Lease. Notwithstanding the foregoing, Sublandlord will not assess a late charge until Sublandlord has given written notice of such late payment for the first late payment in any twelve (12) month period and after Subtenant has not cured such late payment within three (3) business days from receipt of such notice. No other notices will be required during the following twelve (12) months for a late charge to be incurred. Rent for any partial month during the Sublease Term shall be prorated by dividing the number of days in such month that fall within the Sublease Term by the total number of calendar days in such month. Concurrently with the execution of this Sublease, Subtenant shall pay Sublandlord Base Rent for the first month of this Sublease.

(a) It is understood and agreed that the interest of Sublandlord under this Sublease and in the Premises is solely as tenant under the Lease, and that this Sublease and Subtenant’s rights and Sublandlord’s obligations hereunder are subject and subordinate to the Lease in all respects. Sublandlord shall not voluntarily terminate the Lease except pursuant to a right of termination arising out of casualty or condemnation expressly set forth in the Lease, and Sublandlord shall not amend the Lease in a manner adverse to Subtenant in any material respect. In the event that the Lease shall be terminated for any reason, this Sublease shall terminate and Sublandlord shall have no obligation or liability to Subtenant, whether for the corresponding termination of this Sublease, the dispossession of Subtenant from Premises, or otherwise, unless

such termination (a) shall have arisen out of a default under the Lease by Sublandlord not arising out of a default hereunder by Subtenant or (b) shall have been effected by Sublandlord in violation of this Section 2.04(a). Subtenant has received a copy of the Lease and hereby represents and warrants that it has read it and understands all of the provisions therein.

(b) If any term or provision of this Sublease conflicts with any term or provision of the Lease, the terms of this Sublease shall govern with respect to Sublandlord and Subtenant only. All of the terms and conditions contained in the Lease as they may apply to Premises and that constitute obligations of the tenant under the Lease are incorporated herein by this reference and shall be terms and conditions of this Sublease (with each reference therein to “Landlord” “Tenant”, “Leased Premises” and “Lease” to be deemed to refer to Sublandlord, Subtenant, the Premises and Sublease respectively, as appropriate), except for the following provisions of the Lease: Article 1 (except Sections 1.4, 1.5, 1.6 and 1.16 which shall continue to apply), Sections 4.2, 4.3, 4.4, 4.5, Article 5, Sections 6.2, Article 8, Sections 14.4. 19.3, 19.5, 28.1, 33.7, 33.21, 33.25 and Exhibits C, D, F and G. The foregoing incorporation of the Lease, along with all of the terms and conditions set forth in this Sublease, shall constitute the complete terms and conditions of this Sublease (the provisions of the Lease which Subtenant shall be responsible for performing pursuant to the provisions of this Sublease being herein referred to as the “Lease Provisions”). Sublandlord expressly reserves all remedies reserved to Sublandlord, as tenant under the Lease, including, without limitation, the Lease Provisions.

(c) Notwithstanding anything to the contrary in the Lease Provisions, Subtenant shall not be required to disclose any financial statements to Sublandlord or Landlord unless and until such party executes and delivers a commercially reasonable non-disclosure agreement.

(d) Notwithstanding anything to the contrary in the Lease Provisions, upon termination of this Sublease, Subtenant agrees that it shall not remove from the Premises any of Landlord’s furniture, fixtures or equipment, which shall remain the property of Landlord.

(e) Sublandlord shall afford Subtenant the benefit of the rights to the services and utilities which Landlord supplies to the Premises under the Lease (including, without limitation, the services contemplated by Sections 3.4 and 18.1 and Article 11); provided, however, that Sublandlord shall have no obligation or liability with respect to Landlord’s performance or non-performance of any of Landlord’s obligations under the Lease and the sole obligation of the Sublandlord shall be (i) to give notice to Landlord of any nonperformance by Landlord when Sublandlord receives written notice of such non-performance from Subtenant and (ii) to use commercially reasonable efforts to procure performance by Landlord; provided, further, however that Sublandlord shall have no obligation to Subtenant to threaten or commence any litigation or enforcement of formal remedies against Landlord. Notwithstanding the foregoing, if despite such commercially reasonable efforts by Sublandlord to procure the performance by Landlord, Landlord remains in default of its obligations under the Lease, upon the written request of Subtenant, Sublandlord shall assign to Subtenant the right on behalf of Sublandlord to pursue all claims at law or in equity against Landlord at Subtenant’s sole cost and expense.

(f) Subtenant agrees to assume, be bound by and to perform every term, provision, covenant and condition, imposed upon Sublandlord by the Lease Provisions that are incorporated herein pursuant to Section 2.04(b), in accordance with this Sublease. All such obligations of Subtenant shall be for the benefit of, and shall be enforceable by, Sublandlord and/or Landlord. Subtenant agrees not to take or omit (or to permit to be taken or omitted) any action in violation of the terms and conditions of the Lease Provisions as they relate to Premises or any Common Areas. Subtenant shall promptly deliver to Sublandlord copies of any notices received by Subtenant with reference to Premises. Notwithstanding the foregoing, Subtenant shall not be responsible for any obligation of Sublandlord pursuant to the Lease which was required to be performed by Sublandlord prior to the Commencement Date and Subtenant shall not be responsible to indemnify Sublandlord or Landlord for any claims occurring prior to the Commencement Date or to repair and damage or remove any alterations which may exist in the Premises prior to the Commencement Date (unless such claims, damage or obligations arise or relate to actions taken by Subtenant or any Subtenant Party during the Early Occupancy Period).

(g) Whenever in the Lease a time is specified for the giving of any notice or the making of any demand by the tenant thereunder, such time is hereby changed, for the purpose of this Sublease only, by adding two (2) business days thereto and whenever in the Lease a time is specified for the giving of any notice or the making of any demand by the Landlord, such time is hereby changed, for the purpose of this Sublease only, by subtracting two (2) business days therefrom; provided, however, in no event shall Subtenant have less than three (3) business days and at no time shall Subtenant have less than thirty (30) days to make a payment upon receipt of invoice unless such payment is due directly to Landlord and the Lease provides for a shorter period of time in which case such payment shall be due to Landlord in such time as provided in the Lease. It is the purpose and intent of the foregoing provisions to provide Sublandlord with time within which to transmit to Landlord any notices or demands received from Subtenant and to transmit to Subtenant any notices or demands received from Landlord.

(h) To the extent Sublandlord is required to subordinate the Lease and/or this Sublease to any present and future ground or underlying leases of the land on which the Building is located and to the lien of any mortgages or trust deeds now and hereafter in force against the land on which the Building is located or the Building and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security thereof, Subtenant agrees to cooperate with Sublandlord regarding such subordination and to subordinate this Sublease as and to the extent reasonably required by Landlord. Sublandlord agrees to request from any such ground lessor, mortgagee or beneficiary of any deed of trust a written recognition agreement (the “Non-Disturbance Agreement”) providing that Subtenant’s rights and interests shall not be disturbed in the event of any foreclosure on any such lease, mortgage or deed of trust and confirming that Subtenant shall receive all of its rights and services provided for under this Sublease; provided that receipt of such Non-Disturbance Agreement shall not be a condition to the subordination of Subtenant’s rights and interest under this Sublease.

(i) As an inducement to Subtenant to enter into this Sublease, Sublandlord represents and warrants that (i) a true and complete copy of the Lease, together with all supplements, amendments and other modifications thereto, (excluding redacted terms and conditions not relevant to Subtenant) is attached hereto as Exhibit C; (ii) the Lease is in full force

and effect; (iii) it has neither received nor delivered to Landlord a notice of default under the Lease; (iv) to Sublandlord’s knowledge, no uncured default by Sublandlord presently exists under the Lease and Sublandlord is not aware of any event or condition which, with the giving of notice or passage of time or both, could constitute such a default or event of default by Sublandlord under the Lease; (v) to Sublandlord’s knowledge, no uncured default by Landlord presently exists under the Lease and Sublandlord is not aware of any event or condition which, with the giving of notice or passage of time or both, could constitute such a default or event of default by Landlord under the Lease; (vi) to Sublandlord’s knowledge, Sublandlord has not caused or permitted any Hazardous Materials to be stored and/or released in, on or about the Premises or any part thereof, other than those contained in ordinary office products and janitorial supplies or otherwise permitted by Environmental Laws and permitted by the Lease; and (vii) the initial improvements to the Premises were completed by Landlord in accordance with the Lease and all conditions to Sublandlord’s acceptance of the Premises have been satisfied or waived. The phrase to “Sublandlord’s knowledge” shall mean the current, actual knowledge of Dana Kuhn, without any duty of investigation or inquiry. Sublandlord represents and warrants that Dana Kuhn is the person most knowledgeable about the Premises. Subtenant understands that Sublandlord has not occupied the Premises since in or around November, 2013.

(j) Notwithstanding Article 18 of the Lease, Sublandlord shall have no right to terminate this Sublease in the event of a casualty unless the Lease is terminated pursuant to Article 18 thereof.

a. Upon Subtenant’s request, to use reasonable efforts (excluding any legal proceedings), at Subtenant’s expense, to obtain Landlord’s consent or approval whenever required by the Lease (unless, in such instance, Sublandlord shall be entitled to withhold its consent or approval even if Landlord shall have granted its consent or approval).

b. That, if under the Lease any right or remedy of Sublandlord or any duty or obligation of Landlord is subject to or conditioned upon Sublandlord’s making any demand upon Landlord or giving any notice or request to Landlord, if Subtenant shall so request, Sublandlord, at Subtenant’s expense, shall make such demand or give such notice or request, except that Sublandlord shall not be required to request Landlord’s consent or approval with respect to any act or thing as to which Sublandlord shall have determined in accordance with this Sublease to withhold its consent or approval.

c. If Landlord is in default under the Lease, Subtenant may request that Sublandlord pursue litigation or other proceedings against Landlord to enforce, interpret or seek other relief from Landlord in respect of its obligations under the Lease. If Sublandlord fails to commence such action within ten (10) business days following such request (or notifies Subtenant within such time period that Sublandlord elects not to do so), or if following commencement thereof Sublandlord fails to prosecute such action with reasonable diligence, then Subtenant shall have the right (but not the obligation) to commence and/or pursue

such litigation or other proceedings and to obtain such relief as shall be available. If Subtenant elects to initiate such action, Sublandlord shall promptly assign to Subtenant all claims Sublandlord may have against Landlord arising out of the Lease to the extent they relate to the Premises and the Sublease Term, together with Sublandlord’s rights under the Lease with respect to such claims and proceedings. Sublandlord also agrees from time to time to take such other actions and to execute and deliver such assignments and/or other instruments as shall be reasonably necessary or appropriate to assign and/or confirm such rights in Subtenant and, at no cost or expense to Sublandlord, to reasonably cooperate with Subtenant in its efforts to pursue such litigation or other proceedings against Landlord. In the event Subtenant elects to initiate such action, Subtenant may dismiss or discontinue such proceedings at any time and without liability or obligation to Sublandlord; provided that in such event Subtenant shall reassign to Sublandlord the claims assigned to Subtenant pursuant to this Section 2.04(k)(c). In the event Subtenant elects to proceed under this Section 2.04(k)(c), Subtenant shall defend, indemnify, protect and hold Sublandlord harmless from and against any and all claims, damages, demands, causes of action, liabilities, losses, costs and expenses (including without limitation costs of suit and reasonable attorneys’ fees) (collectively, “Costs”) arising from or in connection with Subtenant’s exercise of such rights; provided that this indemnification and Subtenant’s obligation to defend shall not apply to any Costs arising out of (i) the Sublandlord’s default under the Lease, except to the extent that default results from a failure of Subtenant to perform its obligations under this Sublease, or (ii) any liabilities or claims that Landlord may have against Sublandlord not resulting solely and directly from Subtenant’s exercise of its rights under this Section 2.04(k)(c), except to the extent those liabilities or claims result from a failure of Subtenant to perform its obligations under this Sublease.

(l) Sublandlord agrees not to cause a default (or event which would become a default with the giving of notice or passage of time) under the Lease; provided, however, that the foregoing shall not obligate Sublandlord to perform any obligations to the extent the same is the obligation of Subtenant under this Sublease. Notwithstanding anything to the contrary contained in this Sublease, a breach by Sublandlord of the preceding sentence shall constitute a default under this Sublease unless the same is cured by Sublandlord within the applicable cure periods provided for in the Lease. Sublandlord shall defend, indemnify, protect and hold Subtenant harmless from and against any and all claims, damages, demands, causes of action, liabilities, losses, costs and expenses (including without limitation costs of suit and reasonable attorneys’ fees) arising from or in connection with any failure by Sublandlord to make any monthly rental payment to Landlord under the Lease or otherwise breach its obligations under this Section 2.04(l), unless the failure to make such monthly rental payment to Landlord is due to Subtenant’s failure to make payments of Base Rent or Additional Rent to Sublandlord as required under this Sublease.

(m) If Subtenant believes that the Additional Rent amounts payable by Subtenant under Section 2.03(b) of this Sublease in any year is greater than the amount Subtenant was actually obligated to pay in accordance with those provisions, Sublandlord agrees to exercise its audit rights under the Lease and to cooperate with Subtenant in the audit of

Landlord’s books and records in accordance with the Lease. In the event Sublandlord conducts any audit of the Landlord’s books and records under the Lease, Sublandlord shall provide Subtenant with copies of the results of that audit.

(n) Subtenant shall have no liability or obligation with respect to any Hazardous Materials, asbestos-containing materials or mold existing in the Premises prior to the Commencement Date.

2.05 Use of Premises. Subtenant shall use Premises only for general office and administrative purposes but for no other use (“Subtenant’s Use”), all in compliance with the terms and conditions of the Lease.

2.06 Condition of Premises Upon Delivery. Sublandlord shall deliver the entirety of Premises to Subtenant in broom clean condition on the Commencement Date. Other than the foregoing, Subtenant has had the opportunity to inspect the Premises prior to the date of this Sublease and hereby accepts the Premises in its “As-Is” condition as of the Commencement Date of this Sublease, “with all faults” and subject to all reasonable wear, tear and other changes in condition that may occur between the execution of this Sublease and the Commencement Date. Sublandlord makes no representations or warranties whatsoever as to the condition, adequacy or sufficiency of Premises or the Building, any improvements or furnishings therein or on the real estate of which they constitute a part, or any part thereof, for Subtenant’s present or future operations. Sublandlord shall have no obligation to render or supply any work, labor, services, materials, fixtures, equipment, decorations or other items whatsoever to make Premises ready or suitable for Subtenant’s occupancy; nor shall Sublandlord be liable for any defect in Premises (whether latent or patent) or for any limitation on the use of Premises; provided, however, Sublandlord shall remain liable for its obligations under the Lease which have become the obligations of Subtenant under this Sublease up until the Commencement Date. Notwithstanding anything to the contrary, Sublandlord represents and warrants to Subtenant that, as of the Commencement Date, all improvements in the Premises and all building systems servicing the Premises shall be in good operating condition and repair. Such improvements and building systems shall include, without limitation, ceiling, walls, windows, doors, door locks, access systems, mechanical systems, electrical, plumbing, life safety systems, lighting and floor coverings. Pursuant to California Civil Code Section 1938, Sublandlord hereby notifies Subtenant that as of the date of this Sublease, the Premises have not undergone inspection by a “Certified Access Specialist” to determine whether the Premises meet all applicable construction-related accessibility standards under California Civil Code Section 55.53.

(a) Subtenant shall, as to Premises, at all times during the Sublease Term and at Subtenant’s own cost and expense, obtain and maintain the insurance required to be maintained by Sublandlord pursuant to Articles 15 and 16 of the Lease. Such policies of insurance shall name Sublandlord and Landlord as additional parties insured thereunder or additional payees (as applicable), and Subtenant shall deliver to Sublandlord certificates of such insurance as proof of coverage within thirty (30) days after the execution of this Sublease by all parties, and thereafter as may be reasonably required by Sublandlord or Landlord; provided however, Subtenant shall not be obligated to provide a certificate of insurance until at least ten (10) days prior to the expiration of such policy. Insurance maintained by Subtenant under this Sublease shall be primary to insurance carried by Sublandlord or Landlord.

(b) Each casualty, fire and extended coverage or all-perils insurance policy required under this Sublease shall contain a clause in which the underlying insurance carrier waives all rights of subrogation against Sublandlord and Landlord with respect to losses payable under such policies, provided such waiver of subrogation shall not affect the right of the insured to recover thereunder. Subtenant hereby waives all rights of subrogation against Sublandlord to the extent either this Sublease or the Lease provides such waivers by Sublandlord for the benefit of Landlord. Since the waiver of subrogation in the Lease is mutual, then this waiver is deemed mutual in this Sublease. By this paragraph, Sublandlord and Subtenant intend that the risk of loss or damage be borne by Subtenant’s insurance carriers and Subtenant shall look solely to and seek recovery from only its insurance carriers in the event a loss is sustained for which insurance is required under this Sublease.

(c) All personal property belonging to Subtenant or to any other person located in or about Premises shall be at the sole risk of Subtenant or such other person, and Subtenant acknowledges and agrees that neither Sublandlord nor its employees or agents shall be liable for any theft or misappropriation of, or damage or injury to, such property.

(d) Subtenant shall comply with all applicable laws (including, without limitation, all applicable fire codes and rules and regulations of Landlord’s and Sublandlord’s fire insurance underwriters) and all orders and decrees of court and all requirements of other governmental authorities to the extent required under the Lease, and shall not, directly or indirectly, make any use of the Premises which may be prohibited by law, may be dangerous to person or property, or may jeopardize any insurance coverage or may increase the cost of insurance or require additional insurance coverage. If by reason of the failure of Subtenant to comply with the provisions of this Section 2.07(d), any insurance coverage is jeopardized or insurance premiums are increased, Sublandlord shall have the option either to terminate this Sublease or to require Subtenant to make immediate payment of this increased insurance premium.

(e) If Subtenant fails to maintain any insurance which Subtenant is required to maintain pursuant to this Section 2.07, Subtenant shall be liable to Sublandlord for any loss or costs resulting from such failure to maintain. Subtenant may not self-insure against any risks required by this Sublease to be covered by insurance.

(f) Sublandlord makes no representation that the limits of liability specified to be carried by Subtenant under this Section 2.07 are adequate to protect Subtenant. In the event Subtenant believes that any insurance coverage required by this Sublease is insufficient, Subtenant shall provide, at its own expense, such additional insurance as Subtenant deems adequate.

(g) Subtenant shall require each of its contractors and trades people to carry insurance in amounts and standards specified in this Section 2.07 or as Sublandlord or Landlord may from time to time reasonably require, from insurance companies licensed to do business in the State of California.

(h) Subtenant shall immediately furnish Sublandlord with a copy of any written notice received, and a written summary of any oral notice received, from any governmental or quasi-governmental authority, insurance company, inspection bureau or any other third party as it relates to Premises.

(a) Subtenant shall be responsible for and shall pay all maintenance, replacements and repairs as to Premises to the extent Sublandlord is obligated to Landlord to perform such maintenance, replacements and repairs under the Lease. Sublandlord shall have no duty to perform any obligations of Landlord which are, by their nature, the obligations of an owner or manager of real property, provided however, that Sublandlord shall reasonably cooperate with Subtenant in the enforcement of such Landlord obligations under the Lease as required under Section 2.04(e) above. Sublandlord shall have no responsibility for or be liable to Subtenant for any default, failure or delay on the part of Landlord in the performance or observance by Landlord of any of its obligations under the Lease, nor shall such default by Landlord affect this Sublease or waive or defer the performance of any of Subtenant’s obligations under this Sublease except to the extent that such default by Landlord excuses performance by Sublandlord under the Lease.

2.09 Extra Services. Sublandlord hereby grants Subtenant the right to request any Special Cleaning Service, excess electrical current, or after hours HVAC directly from Landlord; provided, that Subtenant shall promptly inform Sublandlord on any such request and hereby agrees to pay any and all charges payable to Landlord and/or Sublandlord (as applicable) for such services under the Lease. In the event Landlord requires such request to be made by Sublandlord, promptly upon request of Subtenant forward such request to Landlord on Subtenant’s behalf.

2.10 Indemnity. Subtenant shall indemnify, defend and hold Sublandlord, Landlord, and their respective partners, affiliates, stockholders, directors, agents and employees (collectively, the “Indemnitees”) harmless from and against any and all costs, claims, demands, expenses, actions, judgments, penalties, fines, damages and liabilities (including reasonable attorneys’ fees), losses of every kind and nature to which any of the Indemnitees may be subject arising from or incurred in connection with (a) any damage to any property or any injury (including but not limited to death) to any person occurring in, on or about the Premises, Building and or Complex to the extent that such injury or damage shall be caused by or arise from any actual or alleged act, neglect, fault, or omission by or of Subtenant or any of Subtenant’s agents, contractors, employees, licensees or business invitees (collectively, the “Subtenant Parties”); (b) the conduct or management of any work or thing whatsoever done by the Subtenant in or about the Premises or from transactions of the Subtenant concerning the Premises; (c) Subtenant’s failure to comply with any and all governmental laws, ordinances and regulations applicable to the use of the Premises or its occupancy to the extent required under the Lease; (d) any violation or alleged violation by Subtenant or any Subtenant Party of any of the requirements, ordinances, statutes, regulations or other laws referenced in Article 10 of the Lease, including, without limitation, the Environmental Laws; (e) any breach of the provisions of Article 10 of the Lease by Subtenant or any of Subtenant’s Parties; (f) any Hazardous Use by Subtenant or any of Subtenant’s Parties on, about or from the Premises of any Hazardous

Material approved by Sublandlord under this Sublease; or (g) any other breach or default on the part of Subtenant in performance of any covenant or agreement on the part of the Subtenant to be performed pursuant to this Sublease; provided, however, the foregoing indemnity shall not be applicable to the extent any claims arise out of or are attributable to the gross negligence or willful misconduct of Sublandlord. Without limiting the foregoing, Subtenant’s obligations under this Section 2.10 shall cover any and all Losses (as such term is defined in Section 10.4 of the Lease) incurred by Sublandlord that are in any way related to any matter covered by the foregoing indemnity. Sublandlord shall defend, indemnify, protect and hold Subtenant harmless from and against any and all claims, damages, demands, causes of action, liabilities, losses, costs and expenses (including without limitation costs of suit and reasonable attorneys’ fees) arising from or in connection with the gross negligence or willful misconduct of Sublandlord. The provisions of this Section 2.10 shall survive the termination of this Sublease with respect to any claims or liability accruing prior to such termination.

(a) Payment on Sublease Execution. Subtenant shall pay Sublandlord upon execution hereof the sum of Thirty Three Thousand Three Hundred Sixty Dollars and Twelve Cents ($33,360.12) as a Security Deposit (the “Security Deposit”). Sublandlord shall not be required to (1) keep said deposit separate from its general accounts, or (2) pay interest, or other increment for its use. If Subtenant fails to pay Rent or other charges when due hereunder, or otherwise defaults with respect to any provision of this Sublease, including and not limited to Subtenant’s obligation to restore or clean the Premises following vacation thereof, and such failures or default continue beyond the applicable notice and cure period set forth herein (if any), Sublandlord may use or apply the Security deposit (or a portion thereof) for the payment of any rent or other charges in default, or for the payment of any other sum to which Sublandlord may become obligated by reason of Subtenant’s default, or to compensate Sublandlord for any loss or damage which Sublandlord may suffer thereby. Sublandlord may retain such portion of the Security Deposit as it reasonably deems necessary to restore or clean the Premises following vacation by Subtenant. The Security Deposit is not to be characterized as rent until and unless so applied in respect of a default by Subtenant. Subtenant hereby waives the provisions of Section 1950.7 (excluding subsection (b)) of the California Civil Code and all other provisions of law, now or hereafter in force, which provide that Sublandlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by Subtenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Sublandlord for any other loss or damage, foreseeable or unforeseeable, caused by the act or omission of Subtenant or any officer, employee, agent or invitee of Subtenant.

(b) Restoration of Deposit. If Sublandlord elects to use or apply all or any portion of the Security Deposit as provided in this Section 2.11, Subtenant shall within ten (10) days after written demand therefor deposit with Sublandlord in cash, an amount equal to that portion of the Security Deposit used or applied by Sublandlord, and Subtenant’s failure to so do shall be a an “Event of Default” under this Sublease. The ten (10) day notice specified in the preceding sentence shall insofar as not prohibited by law, constitute full satisfaction of notice of default provisions required by law or ordinance. Should Subtenant faithfully and fully comply with all of the terms, covenants and conditions of this Sublease, within thirty (30) days following

the expiration of the Sublease Term and Subtenant having vacated the Premises, the Security Deposit or any balance thereof shall be returned to Subtenant or, at the option of Sublandlord, to the last assignee of Subtenant’s interest in this Sublease.

2.12 Telecommunication Services. To the extent permitted in the Lease, Subtenant shall have the right to contract directly with telecommunications and media service providers (each a “Telecommunication Provider”) of Subtenant’s choice. Subtenant shall promptly pay and be solely responsible for the cost of such service. Sublandlord shall not be obligated to incur any expense, liability or costs in connection with any Telecommunication Provider proposed by Subtenant. Subtenant will have access and use of the existing cabling and wiring during the Sublease Term, all in accordance with the terms and provisions of this Sublease and the Lease.

2.13 Alterations and Additions. Notwithstanding any rights to make alterations or additions that Sublandlord may have under the Lease, Subtenant shall not make any alterations or additions to Premises, the electrical equipment or building systems in Premises or the Building without the prior written consent of Sublandlord, which consent shall not be unreasonably withheld, conditioned or delayed unless Sublandlord is unable to obtain Landlord’s consent to such alterations or additions, which consent Sublandlord shall use good faith commercially reasonable efforts to obtain as soon as possible upon request by Subtenant. Any alterations or additions to Premises permitted by Sublandlord shall be made in strict accordance with the terms of the Lease and, at the expiration or earlier termination of this Sublease, shall remain in Premises or be removed from Premises, at Subtenant’s sole cost and expense, as may be directed by Sublandlord or Landlord and in a manner consistent with the applicable provisions of the Lease.

2.14 Signage. Subject to the terms of the Lease, Sublandlord grants to Subtenant all rights to signage granted to Sublandlord under the Lease. On or prior to the Commencement Date, Sublandlord shall cooperate with Landlord and Subtenant to replace the existing signage for the Premises and to afford Subtenant the benefits conferred under Article 23 of the Lease.

2.15 Parking. Sublandlord hereby grants Subtenant the rights to use the Parking Spaces on the terms and conditions set forth in Section 3.4(c) of the Lease. Without limiting the foregoing, Subtenant shall furnish Sublandlord and Landlord with a list of employees’ vehicle license numbers within fifteen (15) days of the Commencement Date and thereafter shall notify Landlord and Sublandlord of any changes within fifteen (15) days of any such request.

2.16 Early Access. Commencing as soon as Landlord issues its written consent to this Sublease and ending on the Commencement Date (if any, the “Early Occupancy Period”), Subtenant shall have the right to enter the Premises for the sole purposes of installing Subtenant’s computer equipment, phone and cabling, furniture, fixtures and other equipment. During the Early Occupancy Period, Subtenant shall enter and occupy the Premises subject to all of the terms and provisions of this Sublease, except that during such period Subtenant shall not be required to pay Base Rent, Additional Rent or other amounts which are otherwise required to be paid by Subtenant to Sublandlord under this Sublease as long as Subtenant shall not open for business or conduct any operations from the Premises during this period.

2.17 Assignment or Subletting by Subtenant. Except for a Permitted Transfer described in Section 21.5 of the Lease, Subtenant shall not suffer a Transfer of the Leased Premises (as defined in the Lease) or any interest therein or any part thereof, or any right or privilege appurtenant thereto without the prior written consent of Sublandlord and in strict accordance with the terms and conditions of Article 21 of the Lease which is incorporated herein as if set forth in full, which consent shall not be unreasonably withheld, conditioned or delayed. For avoidance of doubt, it shall be reasonable for Sublandlord to withhold its consent to any Transfer if Sublandlord is unable to obtain the consent of Landlord to any such Transfer if required under Article 21 of the Lease. Without limiting the incorporation of Article 21 as set forth above, and for avoidance of doubt, Subtenant shall pay to Sublandlord on a monthly basis, fifty percent (50%) of all rent, additional rent or other consideration payable by any transferee and received by Subtenant in connection with any Transfer of the Premises in excess of the Rent payable by Subtenant under this Sublease, on a per rentable square foot basis if less than all of the Premises are transferred, after deducting reasonable expenses actually incurred by Subtenant in connection therewith for (i) improvements to the Premises made and paid for by Subtenant in connection with the transfer; (ii) reasonable brokerage commissions paid by Subtenant to unaffiliated third party licensed real estate brokers in connection with such transfer; and (iii) reasonable legal fees incurred in connection with any such transfer. The amount so derived shall be paid with Subtenant’s Rent payments due hereunder.

2.18 Surrender of Premises. Upon the expiration or early termination of this Sublease or Subtenant’s right to possession of Premises, Subtenant shall surrender the Premises to Sublandlord in the condition required by the Lease Provisions; provided, however, Subtenant shall not be required to surrender the Premises in better condition that as existed as of the Commencement Date, normal wear and tear, casualty or condemnation excepted, nor shall Subtenant be responsible to remove any alterations or improvements existing in the Premises prior to the Early Occupancy Period.

2.19 Default. If the Subtenant shall fail to perform or observe any of the terms, provisions, covenants or conditions of this Sublease or of the Lease Provisions, and such failure continues beyond the expiration of the notice and cure period provided in Article 24 of the Lease (an “Event of Default”), Sublandlord shall have all the rights of Landlord under the Lease and Subtenant shall be subject to all provisions with respect to a default by Tenant under the Lease. Without limiting the generality of the foregoing, Sublandlord shall have the remedy described in California Civil Code Section 1951.4 (Sublandlord may continue this Sublease in effect after Subtenant’s breach, even if Subtenant has abandoned Premises, and enforce all of Sublandlord’s rights and remedies under this Sublease, including the right to recover rent as it becomes due, if Subtenant has the right to sublet or assign, subject only to reasonable limitations). In addition to any right of Sublandlord under the Lease, upon an Event of Default by Subtenant, Sublandlord may thereafter at any time terminate this Sublease and reenter Premises, and/or require immediate payment by Subtenant of all monetary obligations of Subtenant under this Sublease based on Sublandlord’s reasonable estimation of those costs at such time. All rights and remedies of Sublandlord under this Sublease, the Lease, at law or in equity shall be cumulative, none shall be exclusive of any other, and pursuit of any one right or remedy shall not preclude pursuit of any additional rights or remedies.

In the event Sublandlord receives a notice of default from Landlord pursuant to the Lease, Sublandlord shall promptly forward such notice of default to Subtenant and if such default is not cured by Sublandlord by the day that is two (2) days prior to the date on which the grace or cure period under the Lease shall expire (excepting therefrom, grace periods of fewer than five (5) days, which shall expire on the day prior to the expiration date set forth in the Lease), Subtenant may, in addition to all other rights and remedies Subtenant may have hereunder, at law, or in equity, but shall have no obligation to do so whatsoever, perform such obligation directly in a commercially reasonable manner. If such notice of default is given by Landlord due to a default of Sublandlord under Section 24.1 of the Lease, then, provided that Subtenant is not in default of any of its obligations under this Sublease beyond any applicable notice and cure period, Sublandlord shall pay the actual and reasonable out-of-pocket costs incurred by Subtenant in connection with that cure to Subtenant upon demand, plus interest from the date of demand through and including the date of payment at 5% per annum. In the event Sublandlord fails to pay the amount demanded by Subtenant under this Paragraph 2.19 within ten (10) days after demand, Subtenant may offset that amount against future payments of rent becoming due under this Sublease until such amount is satisfied; provided, however, that such offset right shall not apply if Sublandlord shall have given Subtenant notice that Sublandlord is disputing the notice of default from Landlord that relates to the obligation performed by Subtenant and Sublandlord’s dispute is bona fide and made in good faith. If a default notice is given by Landlord, Subtenant may request that Sublandlord notify Subtenant as to whether Sublandlord disputes that default notice and Sublandlord shall respond to that request within three (3) business days after receipt of that request.

2.20 Landlord Notice. This Sublease, and the rights and obligations of Subtenant under this Sublease, are subject to the condition precedent that Landlord issue its written consent to this Sublease. Sublandlord shall deliver notice to Landlord promptly after the full execution of this Sublease.

2.21 Notices.

Except as otherwise set forth in this Sublease, Sublandlord makes no warranty, express or implied, regarding such services, facilities or equipment, nor does Sublandlord make any warranty that such services, facilities or equipment are fit for any particular purpose or merchantable; and Subtenant acknowledges that Subtenant has inspected such services, facilities and equipment and has relied only upon Subtenant’s own inspection regarding them and not on any representation made by Sublandlord concerning their performance or suitability.

Sublandlord and Subtenant represent and warrant to each other that they have not dealt with any real estate broker, agent or finder in connection with this Sublease other than Cassidy Turley who is acting as dual agent to Sublandlord and Subtenant in this transaction (“Broker”).

Subtenant will indemnify, defend and hold Sublandlord harmless from and against any and all costs, expenses or liability for commissions or other

compensation or charges claimed by any finder, broker or agent other than the Broker based on dealings with Subtenant with respect to this Sublease. Sublandlord will indemnify, defend and hold Subtenant harmless from and against any and all costs, expenses or liability for commissions or other compensation or charges claimed by any finder, broker or agent other than the Broker based on dealings with Sublandlord with respect to this Sublease. The provisions of this Section shall survive the expiration or earlier termination of this Sublease.

2.25 Attorneys’ Fees. Notwithstanding anything in this Sublease to the contrary, in the event of legal action between Sublandlord and Subtenant as a result of any alleged default by either party hereunder, the prevailing party shall be entitled to entry of judgment including reimbursement by the other party for reasonable attorneys’ fees and costs incurred by the prevailing party in connection with such action.

Notwithstanding the foregoing, Subtenant shall be entitled to receive, or prosecute a separate claim for an award for a temporary taking of Premises or a portion thereof by a condemnor where this Sublease is not terminated (to the extent such award relates to the unexpired Sublease Term), or an award separately designated for relocation expenses or the interruption of or damage to Subtenant’s business or as compensation for Subtenant’s personal property.

2.31 Covenant of Quiet Enjoyment. Sublandlord warrants and agrees that so long as Subtenant shall observe and perform the obligations imposed upon it in this Sublease, Subtenant shall at all times during the Sublease Term peacefully and quietly have and enjoy the possession and use of Premises free from interference from Sublandlord or anyone claiming by or through Sublandlord.

Sublandlord agrees to use commercially reasonable efforts to minimize any unreasonable interference with Subtenant’s access to or use of the Premises for Subtenant’s normal business operations as a result of Sublandlord’s exercise of its rights under this Section 2.32.

2.33 Captions and Headings. The titles or headings of the various sections and paragraphs of this Sublease are intended solely for convenience of reference and are not intended and shall not be deemed to or in any way be used to modify, explain or place any construction upon any of the provisions of this Sublease.

2.34 Counterparts. This Sublease may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto

IN WITNESS WHEREOF, Sublandlord and Subtenant have executed this Sublease Agreement effective as of the day and year first above written.

Exhibit B of the Lease (Floor Plan of Leased Premises) is incorporated as if fully set forth herein.

THIS OFFICE LEASE (“Lease”) is entered and dated for reference purposes only as November 13, 2012 (the “Lease Reference Date”), by and between “Landlord” and “Tenant” (as such terms are defined below).

In addition to the terms defined throughout this Lease, the following salient terms shall have the following meanings when referred to in this Lease:

The terms defined in this Article 2 shall, for all purposes of this Lease and all agreements supplemental hereto, have the meanings herein specified, unless expressly stated otherwise.

“Base Operating Costs” means the Operating Costs for the calendar year set forth in Section 1.10 hereof as such Operating Costs shall be increased to be what the Operating Costs would have been if the Building were one hundred percent (100%) leased and occupied during such calendar year. Additionally, if any new types of insurance coverage are obtained or effected by Landlord during any calendar year after the Base Year (but is not obtained or effected during the Base Year) then the cost of such new type of insurance shall be added to the Insurance Cost element of the Base Operating Costs (but at the rate which would have been in effect during the Base Year) for the year which such change in insurance is initially obtained or effected until such time as Landlord elects to no longer carry such new type of insurance.

“Base Taxes” means the Taxes for the calendar year set forth in Section 1.10 hereof.

“Commencement Date” shall mean the earlier of (a) the date by which the Tenant Improvements to be constructed by Landlord pursuant to Exhibit C, if any, have been “Substantially Completed,” subject to “Tenant Delays” and “Force Majeure Delays” (as such terms are defined in Exhibit C), or (b) the date Tenant takes possession of the Leased Premises for purposes of commencing business and not for early access under Section 4.3. However, if there is any delay in Substantially Completing the Tenant Improvements due to any Tenant Delay, then such delay shall thereupon effect a postponement of the date by which Landlord is obligated to substantially complete the Tenant Improvements; however, the Commencement Date shall be deemed the date the Tenant Improvements would have been Substantially Completed but for the Tenant Delays. Thus, the date for commencement of the free rent, Rent and all additional rent shall not be delayed by Tenant Delay.

“Common Areas” shall mean all areas and facilities outside the Leased Premises within the exterior boundaries of the parcel of land containing the Building of which the Leased Premises form a part, together with the parking and access areas within the Complex, all as provided and designated by Landlord from time to time for the general use and convenience of Tenant and of other tenants of Landlord having the common use of such areas, and their respective authorized representatives and invitees. As of the date of this Lease, Common Areas include, without limitation, corridors, stairways, elevator shafts, janitor rooms in the Building, the driveways, parking areas and landscaped areas in the Complex.

“Insurance Costs” shall mean all premiums and costs and expenses for all policies of insurance which may be obtained by Landlord in its discretion for (a) the Leased Premises, Building and the Common Areas of the Complex, or any blanket policies which include the Building or Complex, covering damage thereto and loss of rents caused by fire and other perils Landlord elects to cover, including, without limitation, coverage for earthquakes and floods, (b) commercial general liability insurance for the benefit of Landlord and its designees and (c) such other coverage Landlord elects to obtain for the Leased Premises, Building or Common Areas of the Complex, including, without limitation, coverage for environmental liability and losses.

“Lease Year” means the calendar year, or portion thereof, following the Commencement Date and during the Term, the whole or any part of which period is included within the Term.

“Operating Costs” means the total amounts paid or payable, whether by Landlord or others on behalf of Landlord, in connection with the ownership, maintenance, repair, replacement and operations of the Building and the Common Areas of the Complex in accordance with Landlord’s standard operating and accounting procedures. If the Complex consists of multiple buildings, certain Operating Costs may pertain to a particular building(s) and other Operating Costs to the Complex as a whole (such as Operating Costs for the Common Areas of the Complex). Operating Costs applicable to any particular building within the Complex shall be charged to the building in question whose tenants shall be responsible for payment of their respective proportionate shares in the pertinent building and other Operating Costs applicable to the Complex (such as the Common Areas of the Complex) shall be charged to each building in the Complex (including the Building) with the tenants in each such building being responsible for paying their respective proportionate shares in such building of such costs to the extent required under the applicable leases. Landlord shall in good faith attempt to equitably allocate such Operating Costs to the buildings (including the Building). Operating Costs shall include, but not be limited to, the aggregate of the amount paid for:

(1) all fuel used in heating and air conditioning of the Building and Common Areas of the Complex;

(2) the amount paid or payable for all electricity furnished by Landlord to the Common Areas of the Complex (other than electricity furnished to and paid for by other tenants by reason of their extraordinary consumption of electricity and that furnished to the other building in the Complex for which the tenants of such other building are responsible for such electrical costs);

(4) the amount paid or payable for all hot and cold water (other than that chargeable to Tenants by reason of their extraordinary consumption of water and that furnished to other buildings in the Complex for which the tenants of such other building are responsible for such water costs) and sewer costs;

(6) painting for exterior walls of the Building and the Common Areas of the Complex; managerial and administrative expenses; the total charges of any independent contractors employed in the repair, care, operation, maintenance, and cleaning of the Building and Common Areas of the Complex;

(7) the amount paid or payable for all supplies occasioned by everyday wear and tear;

(8) the costs of climate control, window and exterior wall cleaning, telephone and utility costs of the Building and Common Areas of the Complex;

(10) fees for management, including, without limitation, office rent, supplies, equipment, salaries, wages, bonuses and other compensation (including fringe benefits, vacation, holidays and other paid absence benefits) relating to employees of Landlord or its agents to the extent engaged in the management, operation, repair, or maintenance of the Building and/or Common Areas of the Complex;

(18) community association dues, assessments and charges and property owners’ association dues, assessments and charges which may be imposed upon Landlord by virtue of any recorded instrument affecting title to the Building, including without limitation, any reciprocal easement agreement and covenants, conditions, easements and restrictions of record, and the cost of any licenses, permits and inspection fees;

(19) all non-capital costs to upgrade, improve or change the utility, efficiency or capacity of any utility or telecommunication system serving the Building and the Common Areas of the Complex;

(20) the repair and replacement, resurfacing and/or repaving of any paved areas, curbs or gutters within the Building or Common Areas of the Complex;

(21) the repair and replacement of any equipment or facilities serving or located within the Complex;

(22) the cost of any capital repairs, improvements and replacements made by the Landlord to the Building or Common Areas of the Complex (“Capital Costs”) which are (a) required to be made in order to conform to changes subsequent to the Commencement Date in any applicable laws, ordinances, rules, regulations, or orders of any governmental authority having jurisdiction over the Building or Common Areas (“laws”), (b) incurred for the purpose of reducing other operating expenses or utility costs, but only to the extent of the anticipated reduction or actual reduction, whichever is greater. The Capital Costs shall be

includable in Operating Costs each year only to the extent of that fraction allocable to the year in question calculated by amortizing such Capital Cost over the reasonably useful life of the improvement resulting therefrom, as determined by Landlord in accordance with reasonable real estate accounting and management principles, consistently applied, with interest on the unamortized balance at the higher of (i) eight percent (8%) per annum; or (ii) the interest rate as may have been paid by Landlord for the funds borrowed for the purpose of performing the work for which the Capital Costs have been expended, but in no event to exceed the highest rate permissible by law; and

Operating Costs shall not include legal, accounting or other professional expenses incurred expressly for negotiating, preparing or enforcing a lease with a particular tenant, or as a result of a default of a specific tenant. Notwithstanding anything to the contrary above, Operating Costs shall further exclude the following:

(a) interest, principal, points and fees on debts or amortization on any mortgage or mortgages or any other debt instrument encumbering the Building or the Leased Premises;

(b) the amount of Operating Costs as are recovered from insurance proceeds or which were required by the Lease to be covered by insurance or which were paid for directly by Tenant or any third party other than as part of such party’s pro rata share of such costs;

(d) Brokers’ or other leasing commissions and costs incurred in connection with entering into new leases or disputes under existing leases;

(f) expenses for any item or service not provided, offered or available to Tenant, but provided exclusively to certain other tenants in the Building;

(i) marketing costs including leasing commissions, attorneys’ fees in connection with the negotiation and preparation of letters, deal memos, letters of intent, leases, subleases and/or assignments, space planning costs, and other costs and expenses incurred in connection with lease, sublease and/or assignment negotiations and transactions with present or prospective tenants or other occupants of the Building;

(j) costs for acquisition of sculpture, paintings or other objects of art, except to the extent to replace, when necessary, any sculpture, paintings or other objects of art existing at the Complex as of the date of this Lease so long as such item replaced is of like kind and quality;

(k) any costs, fines or penalties incurred due to violations by Landlord of any legal requirement which may have been in effect as of the Commencement Date of this Lease;

(l) costs for the removal or abatement of Hazardous Materials to the extent required by applicable law to be removed or abated; provided, however, that (A) the costs of routine monitoring of and testing for hazardous materials in, on, or about the Building, and (B) costs incurred in the cleanup or remediation of de minimis amounts of hazardous materials customarily used in office buildings or used to operate motor vehicles and customarily found in parking facilities shall be included as Operating Costs;

(m) expenses for tenant improvement work or allowances, inducements, and other concessions for any tenant;

(n) the cost of any repairs, improvements, or replacements made to remedy any structural defect in the original design or construction of the Building or other buildings in the Complex;

(o) any capital costs, including capital repairs, improvements and replacements made to the Building and capital repairs, improvements and replacements of Building equipment or systems, except as expressly provided in clause (22) of the definition of Operating Costs above.

Notwithstanding anything to the contrary contained in this Lease, there shall be no duplication of costs, charges or expenses required to be paid by Tenant pursuant to this Lease.

“Proportionate Share” or “Pro Rata Percent” shall be that fraction (converted to a percentage) the numerator of which is the Rentable Area (hereinafter defined) of the Leased Premises and the denominator of which is the Rentable Area of the Building, as each may exist from time to time. Tenant’s Proportionate Share as of the commencement of the Term hereof is specified in Section 1.13. Notwithstanding the preceding provisions of this Section, Tenant’s Proportionate Share as to certain expenses may be calculated differently to yield a higher percentage share for Tenant as to certain expenses in the event Landlord permits other tenants in the Building to directly incur such expenses rather than have Landlord incur the expense in common for the Building (such as, by way of illustration, wherein a tenant performs its own janitorial services). In such case Tenant’s proportionate share of the applicable expense shall be calculated as having as its denominator the Rentable Area of all floors rentable to tenants in the Building less the Rentable Area of tenants who have incurred such expense directly. In any case in which Tenant, with Landlord’s consent, incurs such expenses directly, Tenant’s proportionate share will be calculated specially so that expenses of the same character which are incurred by Landlord for the benefit of other tenants in the Building shall not be prorated to Tenant. Nothing herein shall imply that Landlord will permit Tenant or any other tenant of the Building to incur any Operating Costs. Any such permission shall be in the sole discretion of the Landlord, which Landlord may grant or withhold in its arbitrary judgment.

Notwithstanding anything to the contrary, there shall be excluded from Taxes all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income (as opposed to rents, receipts or income attributable to operations at the Building). With respect to any special assessments which may be levied as part of the Taxes and which may be payable in installments over a period of time, only the amount of the installments due each year shall be included in the Taxes charged to Tenant, whether or not Landlord elects to pay in installments, provided that Landlord has the option of paying said assessment in installments over a period of time (and if Landlord is not permitted to pay the same over time, only the amount which is equitable allocated to the Lease Year shall be passed through).

Such reservation in no way affects the maintenance obligations imposed herein. Landlord may change the shape, size, location, number and extent of the improvements to any portion of the Building or Common Areas of the Complex and/or the address or name of the Building without the consent of Tenant, provided the same do not materially impair Tenant’s ability to conduct its business at the Leased Premises.

This Lease is subordinate to the restrictions.

Under no circumstances shall the right herein granted to use the Common Areas be deemed to include the right to store any property, temporarily or permanently, in the Common Areas. Any such storage shall be permitted only by the prior written consent of Landlord or Landlord’s designated agent, which consent may be revoked at any time. In the event that any unauthorized storage shall occur then Landlord shall have the right, without notice, in addition to such other rights and remedies that it may have, to remove the property and charge the cost to Tenant, which cost shall be immediately payable upon demand by Landlord.

(a) Common Areas Changes. Landlord shall have the right, in Landlord’s sole discretion, from time to time, provided the same do not materially impair Tenant’s ability to conduct its business at the Leased Premises:

(1) To make changes and reductions to the Common Areas, including, without limitation, changes in 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;

(2) To close temporarily any of the Common Areas for maintenance purposes so long as reasonable access to the Leased Premises remains available;

(b) Common Area Maintenance. Landlord shall, in Landlord’s sole but reasonable discretion, maintain the Common Areas (subject to reimbursement pursuant to this Lease) in good working order and condition, establish and enforce reasonable rules and regulations concerning such areas, close any of the Common Areas to whatever extent required in the opinion of Landlord’s counsel to prevent a dedication of any of the Common Areas or the accrual of any rights of any person or of the public to the Common Areas, close temporarily any of the Common Areas for maintenance purposes, and make changes to the Common Areas including, without limitation, changes in the location of driveways, corridors, entrances, exits, the designation of areas for the exclusive use of others (provided such designation of exclusive use areas does not materially and adversely affect Tenant’s use of or access to the Leased Premises), the direction of the flow of traffic or construction of additional buildings thereupon. Landlord may provide security for the Common Areas, but is not obligated to do so. Under no circumstances shall Landlord be liable or responsible for any acts or omissions of any party providing any services to the Common Areas, Building or other improvements, including, without limitation, any security service, notwithstanding anything to the contrary contained in this Lease.

(c) Parking. Provided Tenant is not in default or breach of any term or provision of this Lease and has not vacated the Leased Premises, Tenant is allocated and shall have the non-exclusive and non-preferential right on an unassigned and unreserved basis to use not more than the number of parking spaces specified in Section 1.16 hereof (the “Parking Spaces”) for use by Tenant and Tenant’s Parties (hereinafter defined), while Tenant’s Parties are performing work or services for Tenant at the Leased Premises. The location of the Parking Spaces may be designated from time to time by Landlord. At no time, may Tenant or any of Tenant’s Parties use more than the number of Parking Spaces specified above.

(1) General Procedures. The Parking Spaces will not be separately identified; however Landlord reserves the right in its reasonable discretion to separately identify by signs or other markings the area where Tenant’s Parking Spaces will be located. Landlord shall have no obligation to monitor the use of the parking area, nor shall Landlord be responsible for any loss or damage to any vehicle or other property or for any injury to any person. Said Parking Spaces shall be used only for parking of automobiles no larger than full size passenger automobiles, sport utility vehicles or small pick-up trucks. Tenant shall comply with all rules and regulations which may be adopted by Landlord from time to time. Tenant shall not at any time use more parking spaces than the number allocated to Tenant or park vehicles or the vehicles of others in any portion of the Complex reasonably designated by Landlord as exclusive parking area for others. Tenant shall be responsible for and breach or violation by Tenant’s Parties of the parking regulations and requirements in this Lease. Tenant shall not have the exclusive right to use any specific parking space. If Landlord grants to any other tenant the exclusive right to use any particular parking space(s), Tenant shall not use such spaces. All trucks (other than pick-up trucks) and delivery vehicles shall be (i) temporarily parked for loading and unloading in a location designated by Landlord and otherwise in a manner which does not interfere with the businesses of other occupants of the Complex, and (ii) permitted to remain on the Complex only so long as is reasonably necessary to complete loading and unloading. In the event Landlord elects in its sole and absolute discretion or is required by any law to limit or control parking in the Complex, whether by validation of parking tickets or any other method of assessment, Tenant agrees to participate in such validation or assessment program under such reasonable rules and regulations as are from time to time established by Landlord. Notwithstanding the foregoing, Tenant shall not be required to pay for the use of parking spaces; provided, however the foregoing is not intended to limit Tenant’s obligations regarding Operating Costs. Landlord may temporarily

close off or restrict access to the parking areas from time to time as reasonably necessary to facilitate construction, alteration, or improvements, without incurring any liability to Tenant and without any abatement of Rent under this Lease. Tenant’s continued right to use the Parking Spaces is conditioned on Tenant’s abiding by all rules and regulations prescribed from time to time for the orderly operation and use of the parking facility. Tenant shall use all reasonable efforts to ensure that Tenant’s employees and visitors also comply with such rules and regulations.

(2) Identification. Tenant shall furnish Landlord with a list of its employees’ vehicle license numbers within fifteen (15) days after taking possession of the Leased Premises and thereafter shall notify Landlord of any changes within fifteen (15) days after request by Landlord. Landlord also reserves the right to implement a system requiring that all employees of Tenant attach a parking sticker or parking permit to their vehicles.

(3) Condition. Tenant’s right to use the number of allocated Parking Spaces under Section 3.4(c) and all subsections thereof are expressly conditioned upon Tenant being in occupancy of the Leased Premises.

(4) Remedies. Tenant acknowledges and agrees that a breach of the parking provisions by Tenant or any of Tenant’s Parties may seriously interfere with Landlord’s operation of the Complex and with the rights or occupancy by other tenants of the Complex. Accordingly, Landlord may suffer damages that are not readily ascertainable. Therefore, if Tenant or any of Tenant’s Parties use more than the number of allocated Parking Spaces, or park other than as designated by Landlord for the Parking Spaces, or otherwise fail to comply with any of the foregoing provisions, then Landlord, in addition to any other rights or remedies available at law or in equity or under the Lease, may charge Tenant, as liquidated damages, Twenty-Five Dollars ($25.00) per day during the continuance of each violation during a calendar year after Tenant has been previously notified on two or more occasions during such calendar of a violation, or for each violation that is not cured within one (1) business day’s notice of such violation, and Tenant shall pay such charge within thirty (30) days after request by Landlord. Each vehicle parked in violation of the foregoing provisions shall be deemed a separate violation. In addition, Landlord may immobilize and/or tow from the Complex any vehicle parked in violation hereof, and/or attach violation stickers or notices to such vehicle. The out of pocket cost to remove any such vehicle shall be paid by Tenant within thirty (30) days after request by Landlord. Landlord reserves the right in its sole and absolution discretion to have the parking areas operated by a third party and Tenant shall comply with the rules and regulations of such parking operator.

4.1 Commencement Date. The Term of this Lease shall commence on the Commencement Date and shall be for the Term specified in Section 1.8 hereof (which includes as set forth in Section 1.8 any partial month at the commencement of the Term if the Term commences other than on the first day of the calendar month).

4.2 Acknowledgment of Commencement. After delivery of the Leased Premises to Tenant, Tenant shall execute a written acknowledgment of the date of commencement in the form attached hereto as Exhibit D, and by this reference it shall be incorporated herein. The failure or delay by Landlord to request such acknowledgment or the failure or delay by Tenant in executing and delivery such acknowledgement shall not delay or extend the Commencement Date.

4.3 Pre-Term Possession. Landlord will endeavor to permit Tenant to have early access to the Leased Premises approximately four (4) weeks prior to the Commencement Date for Tenant to make arrangements for the move into the Leased Premises, to perform certain alterations, and to allow Tenant to install its furniture, fixtures and equipment, provided, however, that any such early access shall not interfere or delay with the construction of the Tenant Improvements. Such early access will be provided in a written notice from Landlord to Tenant. Such early access by Tenant, or any agent, employee or contractor of Tenant, to the

Leased Premises prior to the Commencement Date shall be subject to all the provisions of this Lease (other than the payment of Minimum Monthly Rent, Operating Cost and Taxes, and the start of the Minimum Rent Abatement Period), including, without limitation, Tenant’s compliance with the insurance and indemnity requirements of this Lease. Said early access shall not advance the termination date of this Lease. Tenant agrees that it shall not in any way interfere with the progress of the Tenant Improvements. Should such access prove an impediment to the progress of the Tenant Improvements, in Landlord’s reasonable judgment, Landlord may demand that Tenant forthwith vacate the Leased Premises until such time as Landlord’s work is complete, and Tenant shall immediately comply with this demand. Tenant shall comply with all terms and conditions of this Lease during the course of any pre-term possession, except as provided above.

4.4 Delay. If Landlord, for any reason whatsoever, cannot deliver possession of the Leased Premises to Tenant with the Tenant Improvements Substantially Completed at the Estimated Commencement Date, this Lease shall not be void or voidable, nor shall Landlord be liable for any loss or damage resulting therefrom, but in that event, there shall be no accrual of Rent for the period between the Estimated Commencement Date and the Commencement Date, except if the delay is due to a Tenant Delay. For each of day beyond the date which is sixty (60) days following the Estimated Commencement Date (the “Outside Delivery Date”) that the Commencement Date has not occurred (other than to the extent caused directly by any Tenant Delay or Force Majeure), then in addition to the delay of the Commencement Date Tenant shall receive a credit against Base Rent from and after the Commencement Date equal to one (1) day of Base Rent for each such day of delay beyond the Outside Delivery Date.

4.5 Condition and Acceptance of Work. Landlord agrees to deliver possession of the Leased Premises to Tenant in broom clean condition with the base Building HVAC, electrical and plumbing systems serving the Leased Premises in good operating condition. Within thirty (30) days following the date Tenant takes possession of the Leased Premises, Tenant may provide Landlord with a punch list which sets forth any corrective work to be performed by Landlord with respect to work performed by Landlord; provided, however, that Tenant’s obligation to pay Rent and other sums under this Lease shall not be affected thereby. If Tenant fails to submit a punch list to Landlord within such thirty (30) day period, Tenant agrees that by taking possession of the Leased Premises it will conclusively be deemed to have inspected the Leased Premises and found the Leased Premises in satisfactory condition, with all work required of Landlord completed. Tenant acknowledges that neither Landlord, nor any agent, employee or servant of Landlord, has made any representation or warranty, expressed or implied, with respect to the Leased Premises, Building or Common Areas of the Complex, except as specifically provided in this Lease or with respect to the suitability of them to the conduct of Tenant’s business, nor has Landlord agreed to undertake any modifications, alterations, or improvements of the Leased Premises, Building or Common Areas of the Complex, except as specifically provided in this Lease.

4.6 Failure to Take Possession. Tenant’s inability or failure to take possession of the Leased Premises when delivery is tendered by Landlord shall not delay the Commencement Date of the Lease or Tenant’s obligation to pay Rent.

5.1 Payment. Tenant shall pay to Landlord at the address specified in Section 1.1, or at such other place as Landlord may otherwise designate, as “Minimum Monthly Rent” for the Leased Premises the amount specified in Section 1.9 hereof, payable in advance on the first day of each month during the Term of the Lease. If the Term commences on other than the first day of a calendar month, the rent for the first partial month shall be prorated accordingly. All payments of Minimum Monthly Rent (including sums defined as rent in Section 2) shall be in lawful money of the United States, and payable without deduction, offset, counterclaim, prior notice or demand.

5.2 Advance Rent. The first full month’s rent shall be paid by Tenant to Landlord upon the execution of this Lease as advance rent, provided, however, that such amount shall be held by Landlord as an additional “Security Deposit” pursuant to this Lease until it is applied by Landlord to the first Minimum Monthly Rent due hereunder.

5.3 Late Payment. If during any twelve (12) month period, Tenant fails to pay Rent within five (5) business days after receipt of notice that payment is past due on more than three occasions, then Landlord may, by giving written notice to Tenant, require that Tenant pay the Minimum Monthly Rent and other Rent to Landlord quarterly in advance.

6.1 Personal Property, Gross Receipts, Leasing Taxes. This section is intended to deal with impositions or taxes directly attributed to Tenant or this transaction, as distinct from taxes attributable to the Building or Common Areas of the Complex which are to be allocated among various tenants and others. Tenant shall pay before delinquency any and all taxes, assessments, license fees and public charges levied, assessed or imposed against Tenant or Tenant’s estate in this Lease or the property of Tenant situated within the Leased Premises which become due during the Term. On demand by Landlord, Tenant shall furnish Landlord with satisfactory evidence of these payments. If such taxes are included in the bill for the Real Estate Taxes for the Building or Complex, then Tenant shall pay to Landlord as additional rent the amount of such taxes within thirty (30) days after demand from Landlord.

(a) Base Year Increases. If the Operating Costs and Taxes for any Lease Year, calculated on the basis of the greater of (i) actual Operating Costs and Taxes; or (ii) as if the Building were at least one hundred percent (100%) occupied and operational for the whole of such Lease Year, are more than the applicable Base Year Costs for Base Operating Costs and Base Taxes as set forth in section 1.10 (which Base Year Costs shall be calculated separately Operating Costs and Taxes), Tenant shall pay to Landlord its Proportionate Share of any such increase in Operating Costs and/or Taxes, as the case may be, as additional Rent as hereinafter provided.

(b) Partial Year. If any Lease Year of less than twelve (12) months is included within the Term, the amount payable by Tenant for such period shall be prorated on a per diem basis based on the actual number of days in the year).

6.3 Method of Payment. Any additional Rent payable by Tenant under Sections 6.1 and 6.2 hereof shall be paid as follows, unless otherwise provided:

(a) Estimated Monthly. During the Term, Tenant shall pay to Landlord monthly in advance with its payment of Minimum Monthly Rent, one-twelfth (l/12th) of the amount of such additional Rent as estimated by Landlord in advance, in good faith, to be due from Tenant. If at any time during the course of the fiscal year, Landlord determines that Operating Costs and/or Taxes are projected to vary from the then estimated costs for such items by more than ten percent (10%), Landlord may, by written notice to Tenant, revise the estimated Operating Costs and/or Taxes for the balance of such fiscal year, and Tenant’s monthly installments for the remainder of such year shall be adjusted so that by the end of such fiscal year Tenant will have paid to Landlord Tenant’s Proportionate Share of the such revised expenses for such year.

(b) Annual Reconciliation. Annually, as soon as is reasonably possible after the expiration of each Lease Year, Landlord shall prepare in good faith and deliver to Tenant a comparative statement (the “Annual Statement”) setting forth (1) the Operating Costs, Taxes and Insurance Costs for such Lease Year, and (2) the amount of additional Rent as determined in accordance with the provisions of this Article 6.

(c) Adjustment. If the aggregate amount of such estimated additional Rent payments made by Tenant in any Lease Year should be less than the additional Rent due for such year, then Tenant shall pay to

Landlord as additional Rent upon demand the amount of such deficiency. If the aggregate amount of such additional Rent payments made by Tenant in any Lease Year of the Term should be greater than the additional Rent due for such year, then should Tenant not be otherwise in default hereunder, the amount of such excess will be applied by Landlord to the next succeeding installments of such additional Rent due hereunder; and if the Term has expired and there is any such excess for the last year of the Term, the amount thereof will be refunded by Landlord to Tenant within sixty (60) days of the last day of the Term, provided Tenant is not otherwise in default under the terms of this Lease.

(d) Inspection. Tenant shall have the right at its own expense to inspect the books and records of Landlord pertaining to Operating Costs, Insurance Costs and Taxes once in any calendar year by any employee of Tenant or by a certified public accountant mutually acceptable to Landlord and Tenant (provided such certified public accountant charges for its service on an hourly basis and not based on a percentage of any recovery or similar incentive method) at reasonable times, and upon reasonable written notice to Landlord as hereinafter provided. Tenant’s right to inspect such books and records is conditioned upon Tenant first paying Landlord the full amount billed by Landlord. Within ninety (90) days after receipt of Landlord’s annual reconciliation of Operating Costs, Insurance Costs and Taxes, Tenant shall have the right, after at least thirty (30) days prior written notice to Landlord, to inspect at the offices of Landlord or its property manager, the books and records of Landlord pertaining solely to the Operating Costs, Insurance Costs and Taxes for the immediately preceding calendar year covered in such annual reconciliation statement. All expenses of the inspection shall be borne by Tenant and must be completed within fifteen (15) days after commencement of such inspection. If Tenant’s inspection reveals a discrepancy in the comparative annual reconciliation statement, Tenant shall deliver a copy of the inspection report and supporting calculations to Landlord within thirty (30) days after completion of the inspection. If Tenant and Landlord are unable to resolve the discrepancy within thirty (30) days after Landlord’s receipt of the inspection report, either party may upon written notice to the other have the matter decided by an inspection by an independent certified public accounting firm approved by Tenant and Landlord (the “CPA Firm”), which approval shall not be unreasonably withheld or delayed. If the inspection by the CPA Firm shows that the actual aggregate amount of Operating Costs, Insurance Costs or Taxes payable by Tenant is greater than the amount previously paid by Tenant for such accounting period, Tenant shall pay Landlord the difference within thirty (30) days. If the inspection by the CPA Firm shows that the actual applicable amount is less than the amount paid by Tenant, then the difference shall be applied in payment of the next estimated monthly installments of Operating Costs, Insurance Costs and/or Taxes owing by Tenant, or in the event such accounting occurs following the expiration of the Term hereof, such difference shall be refunded to Tenant. Tenant shall pay for the cost of the inspection by the CPA Firm, unless such inspection shows that Landlord overstated the aggregate amount Operating Costs, Insurance Costs or Taxes by more than five percent (5%), in which case Landlord shall pay for the cost of the inspection by the CPA Firm. Tenant acknowledges and agrees that any information revealed in the above described inspection may contain proprietary and sensitive information and that significant damage could result to Landlord if such information were disclosed to any party other than Tenant’s auditors. Tenant shall not in any manner disclose, provide or make available any information revealed by the inspection to any person or entity without Landlord’s prior written consent, which consent may be withheld by Landlord in its sole and absolute discretion.

7.1 Acceptance of Payment. No payment by Tenant or receipt by Landlord of a lesser amount of Minimum Monthly Rent or any other sum due hereunder, shall be deemed to be other than on account of the earliest due rent or payment, nor shall any endorsement or statement on any check or any letter accompanying any such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such rent or payment or pursue any other remedy available in this Lease, at law or in equity. Landlord may accept any partial payment from Tenant without invalidation of any contractual notice required to be given herein (to the extent such contractual notice is required) and without invalidation of any notice required to be given pursuant to California Code of Civil Procedure Section 1161, et seq., or of any successor statute thereto.

8.1 Payment on Lease Execution. Tenant shall pay Landlord upon execution hereof the sum specified in the Salient Lease Terms as a Security Deposit. This sum is designated as a Security Deposit and shall remain the sole and separate property of Landlord until actually repaid to Tenant (or at Landlord’s option the last assignee, if any, of Tenant’s interest hereunder), said sum not being earned by Tenant until all conditions precedent for its payment to Tenant have been fulfilled. As this sum both in equity and at law is Landlord’s separate property, Landlord shall not be required to (1) keep said deposit separate from his general accounts, or (2) pay interest, or other increment for its use. If Tenant fails to pay rent or other charges when due hereunder, or otherwise defaults with respect to any provision of this Lease, including and not limited to Tenant’s obligation to restore or clean the Leased Premises following vacation thereof, Tenant, at Landlord’s election, shall be deemed not to have earned the right to repayment of the Security Deposit, or those portions thereof used or applied by Landlord for the payment of any rent or other charges in default, or for the payment of any other sum to which Landlord may become obligated by reason of Tenant’s default, or to compensate Landlord for any loss or damage which Landlord may suffer thereby. Landlord may retain such portion of the Security Deposit as it reasonably deems necessary to restore or clean the Leased Premises following vacation by Tenant. The Security Deposit is not to be characterized as rent until and unless so applied in respect of a default by Tenant. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, and all other provisions of law, now or hereafter in force, which provide that Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by Tenant or to clean the Leased Premises, it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or unforeseeable, caused by the act or omission of Tenant or any officer, employee, agent or invitee of Tenant.

8.2 Restoration of Deposit. If Landlord elects to use or apply all or any portion of the Security Deposit as provided in Section 8.1, Tenant shall within ten (10) days after written demand therefor pay to Landlord in cash, an amount equal to that portion of the Security Deposit used or applied by Landlord, and Tenant’s failure to so do shall be a material breach of this Lease. The ten (10) day notice specified in the preceding sentence shall insofar as not prohibited by law, constitute full satisfaction of notice of default provisions required by law or ordinance. Should Tenant faithfully and fully comply with all of the terms, covenants and conditions of this Lease, within thirty (30) days following the expiration of the Term and Tenant having vacated the Premises, the Security Deposit or any balance thereof shall be returned to Tenant or, at the option of Landlord, to the last assignee of Tenant’s interest in this Lease.

9.1 Permitted Use. The Leased Premises may be used and occupied only for the purposes specified in Section 1.12 hereof, and for no other purpose or purposes. Tenant shall promptly comply with all laws, ordinances, orders and regulations affecting the Leased Premises, their cleanliness, safety, occupation and use. Tenant shall not use, or permit to be used, the Leased Premises in any manner that will unreasonably disturb any other tenant in the Building or Complex, or obstruct or interfere with the rights of other tenant or occupants of the Building or Complex, or injure or annoy them or create any unreasonable smells, noise or vibrations (taking into account the nature and tenant-mix of the Building). Tenant shall not do, permit or suffer in, on, or about the Leased Premises the sale of any alcoholic liquor without the written consent of Landlord first obtained. Tenant shall not allow the Leased Premises to be used for any improper, unlawful or objectionable purpose.

9.2 Safes, Heavy Equipment. Tenant shall not place a load upon any floor of the Leased Premises which exceeds the lesser of fifty (50) pounds per square foot live load or such other amount specified in writing by Landlord from time to time. Landlord reserves the right to prescribe the weight and position of all safes and heavy installations which Tenant wishes to place in the Leased Premises so as properly to distribute the weight thereof, or to require plans prepared by a qualified structural engineer at Tenant’s sole cost and expense for such heavy objects. Notwithstanding the foregoing, Landlord shall have no liability for any damage caused by the installation of such heavy equipment or safes.

9.3 Machinery. Business machines and mechanical equipment belonging to Tenant which cause noise and/or vibration that may be transmitted to the structure of the Building or to any other leased space to such a degree as to be objectionable to Landlord or to any tenants in the Complex shall be placed and maintained by the party possessing the machines or equipment, at such party’s expense, in settings of cork, rubber or spring type noise and/or vibration eliminators, and Tenant shall take such other measures as needed to eliminate vibration and/or noise. If the noise or vibrations cannot be eliminated, Tenant must remove such equipment within ten (10) days following written notice from Landlord.

9.4 Waste or Nuisance. Tenant shall not commit, or suffer to be committed, any waste upon the Leased Premises, or any nuisance, or other act or thing which may disturb the quiet enjoyment of any other tenant or occupant of the Complex in which the Leased Premises are located.

The judgment of any court of competent jurisdiction, or the admission of Tenant in any action or proceeding against Tenant, whether Landlord be a party thereto or not, that any such requirement, ordinance, statute or regulation pertaining to the Leased Premises has been violated, shall be conclusive of that fact as between Landlord and Tenant. As of the Lease Reference Date, Landlord has not received any notification that the Premises, or any portion thereof, is in violation of the ADA, which alleged violation remains uncured.

(b) Landlord shall, as an Operating Cost, comply with all of the applicable requirements of all municipal, state and federal authorities now in force, or which may hereafter be in force, pertaining to the Common Areas of the Building, but only to the extent required by any governmental authority with jurisdiction thereof; provided, if any work is required to comply with any such law as a result of Tenant’s use of the Leased Premises or the operation of Tenant’s business, or any Alteration made by or on behalf of Tenant, then such work shall be performed by Landlord at the sole cost and expense of Tenant.

However, without the necessity of obtaining such prior written consent, Tenant shall be entitled to use and store only those Hazardous Materials which are (i) typically used in the ordinary course of business in an office for use in the manner for which they were designed and in such limited amounts as may be normal, customary and necessary for Tenant’s business in the Leased Premises, and (ii) in full compliance with Environmental Laws, and all judicial and administrative decisions pertaining thereto.

The cost of all such inspections, tests and investigations shall be borne by Tenant if Tenant is in breach of Section 10.3 of this Lease. Neither any action nor inaction on the part of Landlord pursuant to this Section 10.3(e) shall be deemed in any way to release Tenant from, or in any way modify or alter, Tenant’s responsibilities, obligations, and/or liabilities incurred pursuant to Section 10.3 hereof.

10.4 Indemnity. Tenant shall indemnify, hold harmless, and, at Landlord’s option (with such attorneys as Landlord may approve in advance and in writing), defend Landlord and Landlord’s officers, directors, shareholders, partners, members, managers, employees, contractors, property managers, agents and mortgagees and other lien holders, from and against any and all “Losses” (hereinafter defined) arising from or related to: (a) any violation or alleged violation by Tenant or any of Tenant’s Parties of any of the requirements, ordinances, statutes, regulations or other laws referred to in this Article 10, including, without limitation, the Environmental Laws; (b) any breach of the provisions of this Article 10 by Tenant or any of Tenant’s Parties; or (c) any Hazardous Use by Tenant or any Tenant Parties on, about or from the Leased Premises of any Hazardous Material approved by Landlord under this Lease.

So long as Tenant is not in default under any of the covenants of this Lease, Landlord shall provide climate control to the Leased Premises from 8:00 a.m. to 6:00 p.m. (the “Climate Control Hours”) on weekdays (Saturdays, Sundays and holidays excepted) to maintain a temperature adequate for comfortable occupancy, provided that Landlord shall have no responsibility or liability for failure to supply climate control service when making repairs, alterations or improvements or when prevented from so doing by strikes or any cause beyond Landlord’s reasonable control. Any climate control furnished for periods not within the Climate Control Hours pursuant to Tenant’s request shall be at Tenant’s sole cost and expense in accordance with rate schedules promulgated by Landlord from time to time. As of the Lease Reference Date, the rate for climate control at times other than the Climate Control Hours is Forty Dollars ($40.00) per hour, with a two (2) hour minimum. Upon request, Landlord shall advise Tenant of the then current rate schedule. Tenant acknowledges that Landlord has installed in the Building a system for the purpose of climate control. Any use of the Leased Premises not in accordance with the design standards or any arrangement of partitioning which interferes with the normal operation of such system may require changes or alterations in the system or ducts through which the climate control system operates. Any changes or alterations so occasioned, if such changes can be accommodated by Landlord’s equipment, shall be made by Tenant at its cost and expense but only with the written consent of Landlord first had and obtained, and in accordance with drawings and specifications and by a contractor first approved in writing by Landlord. If installation of partitions, equipment or fixtures by Tenant necessitates the re-balancing of the climate control equipment in the Leased Premises, the same will be performed by Landlord at Tenant’s expense. Any charges to be paid by Tenant hereunder shall be due within thirty (30) days of receipt of an invoice from Landlord.

11.2 Elevator Service. Landlord shall provide elevator service (which may be with or without operator at Landlord’s option) provided that Tenant, its employees, and all other persons using such services shall do so at their own risk.

11.3 Cleaning Public Areas. Landlord shall maintain and keep clean the street level lobbies, sidewalks, truck dock, public corridors and other public portions of the Building.

11.4 Refuse Disposal. Tenant shall pay Landlord, within thirty (30) days of being billed therefor, for the removal from the Leased Premises and the Building of such refuse and rubbish of Tenant as shall exceed that ordinarily accumulated daily in the routine of a reasonable office.

Landlord shall provide cleaning and janitorial service in and about the Complex and Leased Premises five days a week (which is currently scheduled for Monday through Friday, holidays excepted, subject to change by Landlord) in accordance with commercially reasonable standards in an office building in the city in which the Building is located.

11.6 Special Cleaning Service. To the extent that Tenant shall require special or more frequent cleaning and/or janitorial service (hereinafter referred to as “Special Cleaning Service”) Landlord may, upon reasonable advance notice from Tenant, elect to furnish such Special Cleaning Service and Tenant agrees to pay Landlord, within thirty (30) days of being billed therefor, Landlord’s charge for providing such additional service. Special Cleaning Service shall include but shall not be limited to the following to the extent such services are beyond those typically provided pursuant to section 11.5 above:

(a) The cleaning and maintenance of Tenant eating facilities other than the normal and ordinary cleaning and removal of garbage, which special cleaning service shall include, without limitation, the removal of dishes, utensils and excess garbage; it being acknowledged that normal and ordinary cleaning service does not involve placing dishes, glasses and utensils in the dishwasher, cleaning any coffee pot or other cooking mechanism or cleaning the refrigerator or any appliances;

(b) The cleaning and maintenance of Tenant computer centers, including peripheral areas other than the normal and ordinary cleaning and removal of garbage if Tenant so desires;

11.7 Electrical. During the Term of this Lease, there shall be available to the Leased Premises electrical facilities comparable to those supplied in other comparable office buildings in the vicinity of the Building to provide sufficient power for normal lighting and office machines of similar low electrical consumption, and one personal computer for each desk station, but not for any additional computers or extraordinary data processing equipment, special lighting and any other item of electrical equipment which requires a voltage other than one hundred ten (110) volts single phase and is not typically found in an office, as determined by Landlord in its sole, but reasonable discretion; and provided, however, that if the installation of such electrical equipment requires additional air conditioning capacity above that normally provided to tenants of the Building or above standard usage of existing capacity as determined by Landlord in its sole, but reasonable discretion, then the additional air conditioning installation and/or operating costs attributable thereto shall be paid by Tenant. Tenant agrees not to use any apparatus or device in, upon or about the Leased Premises which may in any way increase the amount of such electricity usually furnished or supplied to the Leased Premises, and Tenant further agrees not to connect any apparatus or device to the wires, conduits or pipes or other means by which such electricity is supplied, for the purpose of using additional or unusual amounts of electricity, without the prior written consent of Landlord. At all times, Tenant’s use of electric current shall never exceed Tenant’s share of the capacity of the feeders to the Building or the risers or wiring installation. Tenant shall not install or use or permit the installation or use in the Leased Premises of any computer or electronic data processing or ancillary equipment or any other electrical apparatus designed to operate on electrical current in excess of 110 volts and 5 amps per machine, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed. If Tenant shall require electrical current in excess of that usually furnished or supplied for use of the Leased Premises as general office space, Tenant shall first procure the written consent of Landlord (which consent shall not be unreasonably withheld, conditioned or delayed) to the use thereof and Landlord or Tenant may (i) cause a meter to be installed in or for the Leased Premises, or (ii) if Tenant elects not to install said meter, Landlord may reasonably estimate such excess electrical current. The cost of any meters (including, without limitation, the cost of any installation) or

surveys to estimate such excess electrical current shall be paid by Tenant. Landlord’s approval of any space plan, floor plan, construction plans, specifications, or other drawings or materials regarding the construction of the Tenant Improvements or any alterations shall not be deemed or construed as consent by Landlord under this paragraph to Tenant’s use of such excess electrical current as provided above. Tenant agrees to pay to Landlord, promptly upon demand therefor, all costs of such excess electrical current consumed as calculated by said meters (at the rates charged for such services to the Building by the municipality or the local public utility) or the excess amount specified in said estimate, as the case may be, plus any additional expense incurred in keeping account of the electrical current so consumed, which additional expense Landlord shall advise Tenant within a reasonable time after request by Tenant.

11.8 Water. During the Term of this Lease, if water is made available to the Leased Premises, then water shall be used for drinking, lavatory and office kitchen purposes only as applicable. If Tenant requires, uses or consumes water for any purpose in addition to ordinary drinking, lavatory, and office kitchen purposes (as determined by Landlord in its sole and absolute discretion), as applicable, Landlord may reasonably estimate such excess and Tenant shall pay for same.

11.9 Interruptions. It is understood that Landlord does not warrant that any of the services referred to above or any other services which Landlord may supply will be free from interruption. Tenant acknowledges that any one or more such services may be suspended or reduced by reason of repairs, alterations or improvements necessary to be made, by strikes or accidents, by any cause beyond the reasonable control of Landlord, or by orders or regulations of any federal, state, county or municipal authority. Any such interruption or suspension of services shall not be deemed an eviction (constructive or otherwise) or disturbance of Tenant’s use and possession of the Leased Premises or any part thereof, nor render Landlord liable to Tenant for damages by abatement of Rent or otherwise, nor relieve Tenant of performance of Tenant’s obligations under this Lease. Notwithstanding anything herein to the contrary, if the Premises is made untenantable, inaccessible or unsuitable for the ordinary conduct of Tenant’s business, as a result of an interruption in any of the services required to be provided by Landlord pursuant to this Article 11, then (i) Landlord shall use commercially reasonable good faith efforts to restore the same as soon as is reasonably possible, (ii) if, despite such commercially reasonable good faith efforts by Landlord, such interruption persists for a period in excess of three (3) consecutive business days, then Tenant, as its sole remedy, shall be entitled to receive an abatement of Minimum Monthly Rent and additional Rent payable hereunder during the period beginning on the fourth (4th) consecutive business day of such interruption and ending on the day the utility or service has been restored; provided, however, that in the event such interruption is not due to Landlord’s negligence or willful misconduct, then such abatement shall only apply to the extent Landlord collects proceeds (or would have collected had Landlord tendered such claim) under the policy of rental-loss insurance the cost of which has been included in Operating Expenses and the proceeds from which are allocable to the Premises.

11.10 Conservation. Tenant agrees to comply with the conservation, use and recycling policies and practices from time to time reasonably established by Landlord for the use of utilities and services supplied by Landlord. Landlord may reduce the utilities supplied to the Leased Premises and the Common Areas as required or permitted by any mandatory or voluntary water, energy or other conservation statute, regulation, order or allocation or other program, and the utility charges payable by Tenant hereunder may include excess usage penalties or surcharges as may, from time to time, be imposed on Landlord or the Premises as a result of Tenant’s failure to comply with any such conservation statute, regulation, or order.

11.11 Excess Usage. In addition to Tenant’s Proportionate Share of Operating Costs, Tenant shall pay for (the “Excess Utility Costs”) (i) all utility costs (including, without limitation, electricity, water and/or natural gas) attributable to any HVAC or other cooling system located in the Leased Premises or elsewhere that provides service to Tenant’s server room, data center or other areas with special equipment or for special use, and (ii) all utility costs consumed at the Leased Premises in excess of normal office use (such as by way of example only, extended hours of operation, heavier use of duplicating, computer, telecommunications or other equipment in excess of the normal use for general office uses, or a density of workers in excess of the normal density for general office uses). Tenant shall pay for such Excess Utility Costs within thirty (30) days after

receipt of a billing from Landlord. Such billing shall be determined in good faith by Landlord based on separate meters, submeters or other measuring devices (such as an eamon demon device) to measure consumption of such utilities at the Leased Premises or otherwise based on a commercially reasonable allocation given Tenant’s use of the Leased Premises. The charge for such excess use may include a commercially reasonable charge for increased wear and tear on existing mechanical equipment caused by Tenant’s excess consumption. Tenant shall pay, as additional rent, for the Excess Utility Costs within thirty (30) days after receipt of a billing from Landlord, and if requested by Landlord, Tenant shall pay for Excess Utility Costs, as additional rent, on an estimated basis in advance on the first day of each month, subject to an annual reconciliation of such Excess Utility Costs.

12.1 Consent of Landlord; Ownership. Tenant shall not make, or suffer to be made, any alterations, additions or improvements, including, without limitation, any alterations, additions or improvements that result in increased telecommunication demands or require the addition of new communication or computer wires, cables and related devises or expand the number of telephone or communication lines dedicated to the Leased Premises by the Building’s telecommunication design (individually, an “alteration” and collectively, “alterations”) to the Leased Premises, or any part thereof, without the written consent of Landlord first had and obtained, which consent shall not be unreasonably withheld, conditioned or delayed. Subject to Section 12.4 below, any alterations, except trade fixtures, shall upon expiration or termination of this Lease become a part of the realty and belong to Landlord. Except as otherwise provided in this Lease, Tenant shall have the right to remove its trade fixtures placed upon the Leased Premises provided that Tenant restores the Leased Premises as indicated below. Notwithstanding the foregoing, Landlord’s consent shall not be required for any alteration to the interior of the Premises that complies with the following requirements: (1) is cosmetic in nature such as painting, (2) does not affect the roof or any area outside of the Premises or require work inside the walls or above the ceiling of the Premises; (3) does not affect the Structural parts of the Building or materially affect electrical, plumbing, HVAC or mechanical systems in the Building or servicing the Premises, or the sprinkler or other life safety system; and (4) costs less than $10,000.00 in the aggregate for all of such Alterations during a calendar year (herein referred to as “Minor Alteration”). Tenant shall provide Landlord with prior written notice of any Minor Alteration that requires a building permit.

12.2 Requirements. Any alteration performed by Tenant shall be subject to strict conformity with the following requirements:

(f) Tenant must obtain the prior written approval (which approval shall not be unreasonably withheld, conditioned or delayed) from Landlord for Tenant’s contractors before the commencement of any work. Tenant’s contractor for any work shall maintain all of the insurance reasonably required by Landlord, including, without limitation, commercial general liability and workers’ compensation.

(g) As a condition of approval of an alteration (but not the Tenant Improvements to be installed pursuant to Exhibit C), the cost of which is reasonably expected to exceed $40,000.00, Landlord may require performance and labor and materialmen’s payment bonds issued by a surety approved by Landlord, in a sum equal to the cost of the alterations guarantying the completion of the alteration free and clear of all liens and other charges in accordance with the Plans. Such bonds shall name Landlord as beneficiary;

(h) The alteration must be performed in a manner such that they will not interfere with the quiet enjoyment of the other tenants in the Complex.

12.3 Liens. Tenant shall keep the Leased Premises and the Complex in which the Leased Premises are situated free from any liens arising out of any work performed, materials furnished or obligations incurred by Tenant. In the event a mechanic’s or other lien is filed against the Leased Premises, Building or the Complex as a result of a claim arising through Tenant, Landlord may demand that Tenant furnish to Landlord a surety bond satisfactory to Landlord in an amount equal to at least one hundred fifty percent (150%) of the amount of the contested lien claim or demand, indemnifying Landlord against liability for the same and holding the Leased Premises free from the effect of such lien or claim. Such bond must be posted within twenty (20) days following notice from Landlord. In addition, Landlord may require Tenant to pay Landlord’s reasonable attorneys’ fees and costs in participating in any action to foreclose such lien if Landlord shall decide it is to its best interest to do so. If Tenant fails to post such bond within said time period, Landlord, after five (5) business days prior written notice to Tenant, may pay the claim prior to the enforcement thereof, in which event Tenant shall reimburse Landlord in full, including attorneys’ fees, for any such expense, as additional rent, with the next due rental.

12.4 Server Room Improvements. Tenant has notified Landlord that Tenant desires to construct and operate a server room within the Leased Premises which may include supplemental cooling equipment (collectively, the “Server Improvements”). Landlord has conceptually approved the Server Improvements and Tenant shall have the right to make the Server Improvements within the Leased Premises, at Tenant’s sole cost and expense, provided that Tenant fully complies with the terms and conditions of this Article 12, including, without limitation, the review and approval by Landlord of detailed plans and specifications and the approval by Landlord of Tenant’s contractor, and provided further that (i) Tenant pays any excess electrical charges attributable to same, (ii) the installation, construction and maintenance thereof is performed by Tenant at Tenant’s sole cost and expense and in compliance with all applicable laws, (iii) the Building and Building systems have sufficient capacity and space to accommodate those facilities, (iv) the area occupied by servers and server rooms does not exceed five percent (5%) of the rentable area of the Leased Premises, and (v) the area occupied by servers and server rooms are served by adequate supplemental HVAC systems installed by Tenant in accordance with this Lease at Tenant’s sole cost and expense, and Tenant pays the cost of all utilities serving those supplemental HVAC systems and servers.

However, Tenant shall ascertain from Landlord at least thirty (30) days prior to the termination of this Lease, whether Landlord desires the Leased Premises, or any part thereof, restored to its condition prior to the making of any alterations, installations and improvements (whether or not permitted hereunder), and if Landlord shall so desire, then Tenant shall forthwith restore said Leased Premises or the designated portions thereof as the case may be, to its original condition, entirely at its own expense, excepting normal wear and tear; provided, however, Tenant shall not be obligated to remove any alterations, installations or improvements if, at the time Tenant requested Landlord’s approval (or notified Landlord of the same), Tenant requested of Landlord in writing that Landlord inform Tenant of whether or not Landlord would

require Tenant to remove the same, and at the time Landlord granted its approval, it did not inform Tenant that Landlord would require Tenant to remove such alteration, installation or improvement at the expiration of this Lease. All damage to the Leased Premises caused by the removal of such trade fixtures and other personal property that Tenant is permitted to remove under the terms of this Lease and/or such restoration shall be repaired by Tenant at its sole cost and expense prior to termination.

13.1 Use of Leased Premises. No use shall be made or permitted to be made on the Leased Premises, nor acts done, which will increase the existing rate of insurance upon the building in which the Leased Premises are located or upon any other Building in the Complex or cause the cancellation of any insurance policy covering the Building, or any part thereof, nor shall Tenant sell, or permit to be kept, used or sold, in or about the Leased Premises, any article which may be prohibited by the standard form of “All Risk” fire insurance policies. Tenant shall, at its sole cost and expense, comply with any and all requirements pertaining to the Leased Premises, of any insurance organization or company, necessary for the maintenance of reasonable property damage and commercial general liability insurance, covering the Leased Premises, the Building, or the Complex.

13.2 Increase in Premiums. Tenant agrees to pay Landlord, as additional Rent, within ten (10) days after receipt by Tenant of Landlord’s billing therefor, any increase in premiums for insurance policies which may be carried by Landlord on the Leased Premises, Building or Complex to the extent resulting from the negligence or willful misconduct of Tenant or any of its contractors, partners, officers, employees or agents.

13.3 Personal Property Insurance. Tenant shall maintain in full force and effect on alterations, additions, improvements, carpeting, floor coverings, panelings, decorations, fixtures, inventory and other business personal property situated in or about the Leased Premises a policy or policies providing protection against any peril included within the classification “All Risk” to the extent of one hundred percent (100%) of their replacement cost, or that percentage of the replacement cost required to negate the effect of a co-insurance provision, whichever is greater. No such policy shall have a deductible in a greater amount than FIFTEEN THOUSAND DOLLARS ($15,000.00). Tenant shall also insure in the same manner the physical value of all its leasehold improvements and alterations in the Leased Premises. During the term of this Lease, the proceeds from any such policy or policies of insurance shall be used for the repair or replacement of the fixtures, equipment, and leasehold improvements so insured. Landlord shall have no interest in said insurance (except as a joint loss payee, as its interests may appear, with respect to any alterations or other leasehold improvements made to the Premises), and will sign all documents necessary or proper in connection with the settlement of any claim or loss by Tenant. Tenant shall also maintain business interruption insurance and insurance for all plate glass upon the Leased Premises. All insurance specified in this Section 13.3 to be maintained by Tenant shall be maintained by Tenant at its sole cost.

14.1 Intent and Purpose. This Article 14 is written and agreed to in respect of the intent of the parties to assign the risk of loss, whether resulting from negligence of the parties or otherwise, to the party who is obligated hereunder to cover the risk of such loss with insurance. Thus, the indemnity and waiver of claims provisions of this Lease have as their object, so long as such object is not in violation of public policy, the assignment of risk for a particular casualty to the party carrying the insurance for such risk, without respect to the causation thereof.

14.2 Waiver of Subrogation. So long as their respective insurers so permit, Tenant and Landlord hereby mutually waive their respective rights of recovery against each other for any loss insured by fire, extended coverage, All Risks or other insurance now or hereafter existing for the benefit of the respective party but only to the extent of the net insurance proceeds payable under such policies.

The provisions of this Article shall survive the termination of this Lease with respect to any claims or liability accruing prior to such termination.

(b) Landlord shall protect, indemnify and hold Tenant harmless from and against any and all loss, claims, liability or costs (including court costs and attorney’s fees) incurred by reason of the gross negligence or willful misconduct of Landlord; provided, however, the foregoing indemnity shall not be applicable to the extent any claims arise out of or are attributable to the negligence or willful misconduct of Tenant or Tenant Entities.

The obligations of Tenant under this Section arising by reason of any occurrence taking place during the Lease term shall survive any termination of this Lease.

14.6 Waiver of Claims. Tenant, as a material part of the consideration to be rendered to Landlord, hereby waives all claims against Landlord for damages to goods, wares, merchandise and loss of business in, upon or about the Leased Premises and injury to Tenant, its agents, employees, invitees or third persons, in, upon or about the Leased Premises, Building or Complex from any cause arising at any time, including the failure to provide security or Landlord’s negligence in connection therewith, or the negligence of the parties hereto, except to the extent such damages or injury are caused by the gross negligence or willful actions of Landlord, its agents, officers and employees; provided, however, the foregoing does not waive any direct claims by Tenant’s agents, employees, invitees or other third persons.

Wherever in this Article the term Landlord or Tenant is used and such party is to receive the benefit of a provision contained in this Article, such term shall refer not only to that party but also to its shareholders, officers, directors, employees, partners, members, managers, mortgagees and agents.

15.1 Tenant’s Insurance. Tenant shall, at Tenant’s expense, obtain and keep in force during the term of this Lease, a commercial general liability insurance policy, written on an occurrence basis, insuring Tenant and protecting Landlord and the Landlord Entities against any liability to the public or to any invitee of Tenant or a Landlord Entity against the risks of, bodily injury and property damage, personal injury, contractual liability, completed operations, products liability, host liquor liability, owned and non-owned automobile liability arising out of the use, occupancy or maintenance of the Leased Premises and all areas appurtenant thereto. Such insurance shall be a combined single limit policy in an amount not less than ONE MILLION DOLLARS ($1,000,000.00) per occurrence with a TWO MILLION DOLLARS ($2,000,000.00) annual aggregate. Landlord, the Landlord Entities and any lender and any other party in interest designated by Landlord shall be named as additional insured(s). The policy shall contain cross liability endorsements with coverage for Landlord for the negligence of Tenant even though Landlord is named as an additional insured; shall insure performance by Tenant of the indemnity provisions of this Lease (subject to standard policy exceptions and exclusions); shall be primary, not contributing with, and not in excess of coverage which Landlord may carry; shall provide for severability of interest; shall provide that an act or omission of one of the insured or additional insureds which would void or otherwise reduce coverage shall not void or reduce coverages as to the other insured or additional insureds. The limits of said insurance shall not limit any liability of Tenant hereunder. Not more frequently than every year, if, in the reasonable opinion of Landlord, the amount of liability insurance required hereunder is not adequate, Tenant shall promptly increase said insurance coverage as reasonably required by Landlord.

15.2 Workers’ Compensation Insurance. Tenant shall carry Workers’ Compensation insurance as required by law, including an employers’ liability endorsement.

15.3 Other Insurance. Tenant shall keep in force throughout the Term: (a) Business Auto Liability covering owned, non-owned and hired vehicles with a limit of not less than $1,000,000 per accident; (b) Employers Liability with limits of $1,000,000 each accident, $1,000,000 disease policy limit, $1,000,000 disease—each employee; (c) Business Interruption Insurance for 100% of the 12 months actual loss sustained, and (d) Excess Liability in the amount of $5,000,000. In addition, whenever Tenant shall undertake any alterations, additions or improvements in, to or about the Leased Premises (“Work”) the aforesaid insurance protection must extend to and include injuries to persons and damage to property arising in connection with such Work, without limitation including liability under any applicable structural work act, and such other insurance as Landlord shall require; and the policies of or certificates evidencing such insurance must be delivered to Landlord prior to the commencement of any such Work.

(b) The insurer shall be qualified or authorized to do business in the state in which the Leased Premises are located;

(d) Certificates of insurance shall be delivered to Landlord at commencement of the term and certificates of renewal at least thirty (30) days prior to the expiration of each policy; and

16.2 Tenant’s Insurance Defaults. If Tenant fails to obtain any insurance required of it under the terms of this Lease, and such failure continues for three (3) business days following notice from Landlord, Landlord may, at its option, but is not obligated to, obtain such insurance on behalf of Tenant and bill Tenant, as additional rent, for the cost thereof. Payment shall be due within thirty (30) days of receipt of the billing therefor by Tenant.

18.1 Landlord’s Obligations. Subject to the other provisions of this Lease imposing obligations in this respect upon Tenant, Landlord shall repair, replace and maintain the external and Structural parts of the Building and Common Areas of the Complex, janitor and equipment closets and shafts within the Leased Premises designated by Landlord for use by it in connection with the operation and maintenance of the Complex, the heating, air conditioning and ventilation system, the plumbing and electrical systems, the lights, and all Common Areas. Landlord shall perform such repairs, replacements and maintenance with reasonable dispatch, in a good and workmanlike manner; but Landlord shall not be liable for any damages, direct, indirect or consequential, or for damages for personal discomfort, illness or inconvenience of Tenant by reason of failure of such equipment, facilities or systems or reasonable delays in the performance of such repairs, replacements and maintenance, unless caused by the gross negligence or deliberate act or omission of Landlord. The cost for such repairs, maintenance and replacement shall be included, to the extent permitted under the Lease, in Operating Costs.

18.2 Negligence of Tenant. Subject to Section 14.2, if the Building, the elevators, boilers, engines, pipes or apparatus used for the purpose of climate control of the Building or operating the elevators, or if the water pipes, drainage pipes, electric lighting or other equipment of the Building, or the roof or the outside walls of the Building, fall into a state of disrepair or become damaged or destroyed through the negligence or intentional act of Tenant, its agents, officers, partners, employees or servants, the cost of the necessary repairs, replacements or alterations shall be borne by Tenant who shall pay the same to Landlord as additional charges forthwith on demand.

18.3 Tenant’s Obligations. Tenant shall repair the Leased Premises, including without limiting the generality of the foregoing, all interior partitions and walls, fixtures, Tenant Improvements and alterations in the Leased Premises, fixtures and shelving, and special mechanical and electrical equipment which equipment is not a normal part of the Leased Premises installed by or for Tenant, reasonable wear and tear, damage with respect to which Landlord has an obligation to repair as provided in Section 18.1 and Section 19 hereof only excepted. Landlord may enter and view the state of repair and Tenant will repair in a good and workmanlike manner according to notice in writing.

18.4 Cleaning. Tenant agrees at the end of each business day to leave the Leased Premises in a reasonably clean condition for the purpose of the performance of Landlord’s cleaning services referred to herein.

18.5 Waiver. Tenant waives all rights it may have under law to make repairs at Landlord’s expense.

18.6 Acceptance. Except as to the construction obligations of Landlord, if any, stated in Exhibit C to this Lease and as otherwise provided herein, Tenant shall accept the Leased Premises in “as is” condition as of the date of execution of this Lease by Tenant, and subject to the punch list items referenced in section 4.5, Tenant acknowledges that the Leased Premises in such condition are in good and sanitary order, condition and repair.

19.1 Rights of Termination. In the event the Leased Premises suffers (a) an “uninsured property loss” (as hereinafter defined) or (b) a property loss which cannot be repaired within one hundred eighty (180) days from the date of destruction under the laws and regulations of state, federal, county or municipal authorities, or other authorities with jurisdiction, Landlord may terminate this Lease as of the date of the damage within twenty (20) days of written notice from Landlord to Tenant that the damage from the casualty was an uninsured property loss or that time to restore will exceed such one hundred eighty (180) day period. In the event of a property loss to the Leased Premises which cannot be repaired within one hundred eighty (180) days of the occurrence thereof, Tenant shall also have the right to terminate the Lease by written notice to Landlord within twenty (20) days following notice from Landlord that the time for restoration will exceed such time period. Notwithstanding anything to the contrary contained in this Lease, Tenant shall not have the right to terminate this Lease if the casualty or other loss or damage was caused by the negligence or intentional misconduct of Tenant or any Tenant Entity or a party related to Tenant. For purposes of this Lease, the term “uninsured property loss” shall mean any loss arising from a peril not covered by the standard form of “All Risk” property insurance policy and which costs in excess of $150,000.00 to repair.

19.2 Repairs. In the event of a property loss which may be repaired within one hundred eighty (180) days from the date of the damage, or, in the alternative, in the event the parties do not elect to terminate this Lease under the terms of Section 19.1 above, then this Lease shall continue in full force and effect and Landlord shall forthwith undertake to make such repairs to reconstitute the Leased Premises to as near the condition as existed prior to the property loss as practicable. Landlord shall not be required to repair or replace any damage or loss by or from fire or other cause to any panelings, decorations, partitions, additions, railings, ceilings, floor coverings, office fixtures or any other property or improvements installed on the Leased Premises by, or belonging to, Tenant. Such partial destruction shall in no way annul or void this Lease except that Tenant shall be entitled to a proportionate reduction of Minimum Monthly Rent and Additional Rent following the property loss and until the time the Leased Premises are restored. Such reduction shall be based on the degree of impairment of Tenant’s ability to conduct business at the Leased Premises in the same manner as it conducted its business before the casualty. So long as Tenant conducts its business in the Leased Premises, there shall be no abatement until the parties agree on the amount thereof. If the parties cannot agree within forty-five (45) days of the property loss, the matter shall be submitted to arbitration under the rules of the American Arbitration Association. Upon the resolution of the dispute, the settlement shall be retroactive and Landlord shall within ten (10) days thereafter refund to Tenant any sums due in respect of the reduced rental from the date of the property loss. Landlord’s obligations to restore shall in no way include any construction originally performed by Tenant or subsequently undertaken by Tenant, but shall include solely that property constructed by Landlord prior to commencement of the Term hereof. Notwithstanding anything to the contrary contained in this Lease, in the event the holder of any indebtedness secured by a mortgage or deed of trust covering the Leased Premises, Building and/or Complex requires that any insurance proceeds be applied to such indebtedness, then Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within fifteen (15) days after such requirement is made by any such holder, whereupon this Lease shall end on the date of such damage as if the date of such damage were the date originally fixed in this Lease for the expiration of the Term.

19.3 Repair Costs. The cost of any repairs to be made by Landlord, pursuant to Section 19.2 of this Lease, shall be paid by Landlord utilizing available insurance proceeds. Any deductible for which no insurance proceeds will be obtained under Landlord’s insurance policy shall be included within Operating Costs; provided, however, in no event shall Tenant’s Proportionate Share of any individual casualty deductible exceed an amount equivalent to two (2) months of Minimum Monthly Rent.

19.4 Waiver. Tenant hereby waives all statutory or common law rights of termination in respect to any partial destruction or property loss which Landlord is obligated to repair or may elect to repair under the terms of this Article.

19.5 Landlord’s Election. In the event that the Complex or Building is destroyed to the extent of not less than twenty-five percent (25%) of the replacement cost thereof, Landlord may elect to terminate this Lease, whether the Leased Premises be injured or not, in the same manner as in Section 19.1 above. In all events, a total destruction of the Complex or Building shall terminate this Lease.

19.6 Damage Near End of Term. If at any time during the last twelve (12) months of the term of this Lease there is, in Landlord’s sole opinion, substantial damage to the Premises or the Building, whether or not such casualty is covered in whole or in part by insurance, Landlord, and, if such damage materially interferes with Tenant’s ability to conduct business within the Premise then also Tenant, may cancel and terminate this Lease as of the date of occurrence of such damage by giving written notice to the other within thirty (30) days after the date of occurrence of such damage and Landlord shall have no further liability hereunder. Substantial damage shall be defined as damage that will cost over $50,000.00 to repair.

(a) “Condemnation” means (i) the exercise of any governmental power, whether by legal proceedings or otherwise, by a condemnor and/or (ii) a voluntary sale or transfer by Landlord to any condemnor, either under threat of condemnation or while legal proceedings for condemnation are pending.

(b) “Date of taking” means the date the condemnor has the right to possession of the property being condemned.

(c) “Award” means all compensation, sums or anything of value awarded, paid or received on a total or partial condemnation.

(d) “Condemnor” means any public or quasi-public authority, or private corporation or individual, having the power of condemnation.

20.2 Total Taking. If the Leased Premises are totally taken by condemnation, this Lease shall terminate on the date of taking.

(a) If any portion of the Leased Premises is taken by condemnation, this Lease shall remain in effect, except that Tenant can elect to terminate this Lease if 33-1/3% or more of the total number of square feet in the Leased Premises is taken.

(b) If any part of the Common Areas of the Complex is taken by condemnation, this Lease shall remain in full force and effect so long as there is no material interference with the access to the Leased Premises, except that if thirty percent (30%) or more of the Common Areas is taken by condemnation, Landlord or Tenant shall have the election to terminate this Lease pursuant to this Section.

(c) If fifty percent (50%) or more of the Building in which the Leased Premises are located is taken, Landlord shall have the election to terminate this Lease in the manner prescribed herein.

20.4 Termination or Abatement. If either party elects to terminate this Lease under the provisions of Section 20.3 (such party is hereinafter referred to as the “Terminating Party”), it must terminate by giving notice to the other party (the “Nonterminating Party”) within thirty (30) days after the nature and extent of the taking have been finally determined (the “Decision Period”). The Terminating Party shall notify the Nonterminating Party of the date of termination, which date shall not be earlier than one hundred twenty (120) days after the Terminating Party has notified the Nonterminating Party of its election to terminate nor later than the date of taking. If Notice of Termination is not given within the Decision Period, the Lease shall continue in full force and effect except that Minimum Monthly Rent shall be reduced by subtracting therefrom an amount calculated by multiplying the Minimum Monthly Rent in effect prior to the taking by a fraction the numerator of which is the number of square feet taken from the Leased Premises and the denominator of which is the number of square feet in the Leased Premises prior to the taking.

20.5 Restoration. If there is a partial taking of the Leased Premises and this Lease remains in full force and effect pursuant to this Article, Landlord, at its cost, shall accomplish all necessary restoration so that the Leased Premises is returned as near as practical to its condition immediately prior to the date of the taking, but in no event shall Landlord be obligated to expend more for such restoration than the extent of funds actually paid to Landlord by the condemnor.

20.6 Award. Any award arising from the condemnation or the settlement thereof shall belong to and be paid to Landlord except that Tenant shall receive from the award compensation for the following if specified in the award by the condemning authority, so long as it does not reduce Landlord’s award in respect of the real property: Tenant’s trade fixtures, tangible personal property, goodwill, loss of business and relocation expenses. At all events, Landlord shall be solely entitled to all award in respect of the real property, including the bonus value of the leasehold. Tenant shall not be entitled to any award until Landlord has received the above sum in full.

21.1 Lease is Personal. The purpose of this Lease is to transfer possession of the Leased Premises to Tenant for Tenant’s personal use in return for certain benefits, including rent, to be transferred to the Landlord. Tenant acknowledges and agrees that it has entered into this Lease in order to occupy the Leased Premises for its own personal use and not for the purpose of obtaining the right to assign or sublet the leasehold to others.

21.2 “Transfer of the Leased Premises” Defined. Except for a Permitted Transfer described in section 21.5 hereof, the terms “Transfer of the Leased Premises” or “Transfer” as used herein shall include any of the following, whether voluntary or involuntary and whether effected by death, operation of law or otherwise:

(a) An assignment of all or any part this Lease or subletting of all or any part the Leased Premises or transfer of possession, or right of possession or contingent right of possession of all or any portion of the Leased Premises including, without limitation, concession, mortgage, deed of trust, devise, hypothecation, agency, license, franchise or management agreement, or the occupancy or use by any other person (the agents and servants of Tenant excepted) of any portion of the Leased Premises.

(b) If Tenant is a partnership, limited liability company or other entity other than a corporation described in Section 21.1(c) below:

(1) A change in ownership effected voluntarily, involuntarily, or by operation of law of fifty percent (50%) or more of the partners or members or fifty percent (50%) or more in the aggregate of the partnership or membership interests, whether in a single transaction or series of transactions over a period of time; or

(1) The sale or other transfer of more than an aggregate of fifty percent (50%) of the voting shares of Tenant or more in the aggregate, whether in a single transaction or series of transactions over a period of time;

21.3 No Transfer Without Consent. Except for a Permitted Transfer described in Section 21.5 hereof, Tenant shall not suffer a Transfer of the Leased Premises or any interest therein, or any part thereof, or any right or privilege appurtenant thereto without the prior written consent of Landlord, and a consent to one Transfer of the Leased Premises shall not be deemed to be a consent to any subsequent Transfer of the Leased Premises. Any Transfer of the Leased Premises without such consent in violation hereof shall (i) be voidable, and (ii) terminate this Lease, in either case, at the option of Landlord. The consent by Landlord to any Transfer shall not include consent to the assignment or transferring of any lease renewal option rights or space option rights of the Leased Premises, special privileges or extra services granted to Tenant by this Lease, or addendum or amendment thereto or letter of agreement (and such options, rights, privileges or services shall terminate upon such assignment), unless Landlord specifically grants in writing such options, rights, privileges or services to such assignee or subtenant.

21.4 When Consent Granted. The consent of Landlord to a Transfer may not be unreasonably withheld, conditioned or delayed, provided that it is agreed to be reasonable for Landlord to consider any of the following reasons, which list is not exclusive, in electing to deny consent:

(a) The financial strength of the proposed transferee at the time of the proposed Transfer is not at least equal to that of Tenant at the time of execution of this Lease;

(b) A proposed transferee whose occupation of the Leased Premises would cause a diminution in the reputation of the Complex or the other businesses located therein;

(c) A proposed transferee whose impact or affect on the common facilities or the utility, efficiency or effectiveness of any utility or telecommunication system serving the Building or the Complex or the other occupants of the Complex would be materially adverse, disadvantageous or require improvements or changes in any utility or telecommunication capacity currently serving the Building or the Complex;

(d) A proposed transferee whose occupancy will require a variation in the terms of this Lease (including, without limitation, a variation in the use clause) or which otherwise adversely affects any interest of Landlord;

(f) Either the proposed transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed transferee or an affiliate of the proposed transferee, is negotiating with Landlord to lease space in the Building or in the Complex at such time;

(g) the proposed Transferee is a governmental agency or unit, a non-profit or charitable entity or organization;

(h) Landlord otherwise determines that the proposed Transfer would have the effect of decreasing the value of the Building or the Complex, or materially increasing the expenses associated with operating, maintaining and repairing the Building or the Complex;

(i) the proposed Transferee will use, store or handle Hazardous Materials (defined below) in or about the Leased Premises of a type, nature or quantity not then reasonably acceptable to Landlord; or

(m) the portion of the Leased Premises to be sublet or assigned is irregular in shape with inadequate means of ingress and egress.

21.5 Permitted Transfer. Notwithstanding the foregoing, Landlord’s consent is not required for any Permitted Transfer (as hereinafter defined), provided the following conditions are met.

(a) At least ten (10) business days before the Transfer, Landlord receives written notice of the Transfer (as well as any documents or information reasonably necessary to show the consummation of the Permitted Transfer);

(b) The Permitted Transfer is not a subterfuge by Tenant to avoid its obligations under this Lease;

For purposes hereof, the term “Permitted Transfer” shall mean any Transfer to an entity that (i) is an Affiliate of Tenant, (ii) purchases substantially all of Tenant’s assets, or (iii) is the surviving entity in the event of any merger or consolidation of Tenant with such surviving entity. For purposes hereef “Affiliate” means any entity that controls, is controlled by, or is under common control with Tenant. “Control” means the direct or indirect ownership of more than fifty percent (50%) of the voting securities of an entity or possession of the right to vote more than fifty percent (50%) of the voting interest in the ordinary direction of the entity’s affairs.

21.6 Procedure for Obtaining Consent. In the event Tenant desires to sublet, or permit such occupancy of, the Leased Premises, or any portion thereof, or assign this Lease, Tenant shall give written notice thereof to Landlord at least sixty (60) days but no more than one hundred twenty (120) days prior to the proposed commencement date of such subletting or assignment requiring consent, which notice shall set forth the name of the proposed subtenant or assignee, the relevant terms of any sublease or assignment and copies of financial reports and other relevant financial information of the proposed subtenant or assignee. With respect to a Transfer requiring Landlord’s consent, Landlord need not commence its review of any proposed Transfer, or respond to any request by Tenant with respect to such, unless and until it has received from Tenant adequate

descriptive information concerning the business to be conducted by the proposed transferee, the transferee’s financial capacity, and such other information as may reasonably be required in order to form a prudent judgment as to the acceptability of the proposed Transfer, including, without limitation, the following:

(a) The past two years’ Federal Income Tax returns of the proposed transferee (or in the alternative the past two years’ audited annual Balance Sheets and Profit and Loss statements, certified correct by a Certified Public Accountant);

(b) A resume of the business background and experience of the proposed transferee; and

21.7 Recapture. By written notice to Tenant (the “Termination Notice”) within thirty (30) days following submission to Landlord by Tenant of the information specified in section 21.6, Landlord may (1) terminate this Lease in the event of an assignment of this Lease or sublet of the entire Leased Premises, or (2) terminate this Lease as to the portion of the Leased Premises to be sublet, if the sublet is to be of less than the entire Leased Premises. If Landlord elects to terminate under the provisions hereof, and the area to be terminated is less than the entire Leased Premises, an amendment to this Lease shall be executed in which Tenant’s obligations for rent and other charges shall be reduced in proportion to the reduction in the size of the Leased Premises caused thereby by restating the description of the Leased Premises, and its monetary obligations hereunder shall be reduced by multiplying such obligations by a fraction, the numerator of which is the Rentable Area of the Leased Premises offered for sublease and the denominator of which is the Rentable Area of the Leased Premises immediately prior to such termination, as determined by Landlord in its sole and absolute discretion. In the event Landlord exercises its termination right pursuant to this Section 21.7, Tenant shall have fifteen (15) days following Landlord’s election to terminate to withdraw its Termination Notice and request to the transfer, and in which case, the Lease shall remain in full force and effect.

21.8 Reasonable Restriction. The restrictions on Transfer described in this Lease are acknowledged by Tenant to be reasonable for all purposes, including, without limitation, the provisions of California Civil Code (the “Code”) Section 1951.4(b)(2). Tenant expressly waives any rights which it might otherwise be deemed to possess pursuant to applicable law, including, without limitation, Section 1997.040 of the Code, to limit any remedy of Landlord pursuant to Section 1951.2 or 1951.4 of the Code by means of proof that enforcement of a restriction on use of the Leased Premises would be unreasonable.

21.9 Effect of Transfer. If Landlord consents to a Transfer and does not elect to recapture as provided in section 21.7, the following conditions shall apply:

(a) Each and every covenant, condition or obligation imposed upon Tenant by this Lease and each and every right, remedy or benefit afforded Landlord by this Lease shall not be impaired or diminished as a result of such Transfer.

(b) Tenant shall pay to Landlord on a monthly basis, fifty percent (50%) of all rent, additional rent or other consideration payable by such transferee in connection with the Transfer in excess of the Rent payable by Tenant under this Lease during the term of the Transfer, on a per rentable square foot basis if less than all of the Leased Premises is transferred, after deducting all reasonable expenses actually incurred by Tenant in connection therewith for (i) improvements to the Leased Premises made and paid for by Tenant in connection with the Transfer, (ii) reasonable brokerage commissions in connection with the Transfer paid by Tenant to unaffiliated third party licensed real estate brokers, and (iii) reasonable legal fees incurred in connection with the Transfer. The amount so derived shall be paid with Tenant’s payment of Minimum Monthly Rent. The amount so derived shall be paid with Tenant’s payment of Minimum Monthly Rent.

(c) No Transfer, whether or not consent of Landlord is required hereunder, shall relieve Tenant of its primary obligation to pay the rent and to perform all other obligations to be performed by Tenant hereunder. The acceptance of rent by Landlord from any person shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any Transfer of the Leased Premises.

(d) If Landlord consents to a sublease, such sublease shall not extend beyond the expiration of the Term of this Lease.

(e) No Transfer shall be valid and no transferee shall take possession of the Leased Premises or any part thereof unless, Tenant shall deliver to Landlord, at least ten (10) days prior to the effective date of such Transfer, a duly executed duplicate original of the Transfer instrument in form satisfactory to Landlord which provides that (i) the transferee assumes Tenant’s obligations for the payment of rent and for the full and faithful observance and performance of the covenants, terms and conditions contained herein, (ii) such transferee will, at Landlord’s election, attorn directly to Landlord in the event Tenant’s Lease is terminated for any reason on the terms set forth in the instrument of transfer and (iii) such instrument of transfer contains such other assurances as Landlord reasonably deems necessary.

21.10 Costs. Tenant shall reimburse Landlord as additional rent for Landlord’s reasonable costs and attorneys’ fees incurred in conjunction with the processing and documentation of any proposed Transfer of the Leased Premises, whether or not consent is granted, not to exceed $1,500.00 unless Tenant or its Transferee requests material changes to this Lease or significant changes to Landlord’s form of consent, in which case such monetary limitation shall not apply. The reference to changes in this Lease or Landlord’s form of consent shall not be deemed or constructed as an agreement, commitment or assurance by Landlord that any changes will be made.

22.1 Rights of Landlord. Tenant shall permit Landlord and Landlord’s agents and any mortgagee under a mortgage or beneficiary under a deed of trust encumbering the Building containing the Leased Premises and such party’s agents to enter the Leased Premises upon not less than twenty-four (24) hours’ prior written notice (except in case of emergency in which case Landlord shall endeavor to give such notice as the circumstances may permit, which may be telephonic notice) for the purpose of (a) inspecting the same, (b) maintaining the Building, (c) making repairs, replacements, alterations or additions to any portion of the Building, including the erection and maintenance of such scaffolding, canopies, fences and props as may be required, (d) posting notices of non-responsibility for alterations, additions or repairs, (e) placing upon the Building any usual or ordinary “for sale” signs and showing the space to prospective purchasers, investors and lenders, without any rebate of rent and without any liability to Tenant for any loss of occupation or quiet enjoyment of the Leased Premises thereby occasioned, and (f) during the last twelve (12) months of the Term, placing on the Leased Premises any “to let” or “to lease” signs and marketing and showing the Leased Premises to prospective tenants. This Section in no way affects the maintenance obligations of the parties hereto.

23.1 Approval, Installation and Maintenance. Tenant shall not place on the Leased Premises or on the Building or Common Areas of the Complex, any exterior signs or advertisements nor any interior signs or advertisements that are visible from the exterior of the Leased Premises, without Landlord’s prior written consent, which Landlord reserves the right to withhold for any aesthetic or other reason in its sole and absolute discretion. The cost of installation and regular maintenance of any such signs approved by Landlord shall be at the sole expense of Tenant. At the termination of this Lease, or any extension thereof, Tenant shall remove all its signs, and all damage caused by such removal shall be repaired at Tenant’s expense.

23.2 Lobby and Suite Signage. Landlord will include Tenant’s name in the directory of the lobby in the Building containing the Leased Premises, and Landlord will pay for the initial cost to include Tenant’s name in such directory to the extent a directory exists. Any changes to Tenant’s name or its listing in such directory shall be at Tenant’s expense. At Tenant’s expense, Landlord will also install a sign identifying Tenant’s name next to the main entrance door to the Lease Premises, which sign will be consistent with the Landlord’s standard Building signage for such purposes. Any change to such sign shall be at Tenant’s sole cost and expense.

24.1 Definition. The occurrence of any of the following shall constitute a material default and breach of this Lease by Tenant:

(a) Payment. Any failure by Tenant to pay the rent or to make any other payment required to be made by Tenant hereunder when due; provided, however, that not more frequently than twice each calendar year, Tenant shall not be in default for failure to pay Rent or any other sum unless Tenant fails to make such payment within five (5) business days after receipt of written notice of such failure from Landlord. The foregoing notice and cure period shall not be deemed a waiver or release of the obligation to pay late charges and interest for payments not made when due.

(b) Other Covenants. A failure by Tenant to observe and perform any other provision of this Lease to be observed or performed by Tenant, where such failure continues for thirty (30) days after written notice thereof by Landlord to Tenant; provided, however, that if the nature of the default is such that the same cannot reasonably be cured within the thirty (30) day period allowed, Tenant shall not be deemed to be in default if Tenant shall, within such thirty (30) day period, commence to cure and thereafter diligently prosecute the same to completion. Notwithstanding the foregoing, any failure by Tenant to comply with the terms and conditions contained in Article 15 (Liability Insurance), Article 16 (Insurance Policy Requirements and Insurance Defaults), Article 32 (Estoppel Certificates) and/or Section 33.25 (Financial Statements and Credit Reports) within the time period for performance set forth in such provisions, where such failure continues for five (5) days after written notice of such failure by Landlord to Tenant; or

(c) Receivership. Either (1) the appointment of a receiver (except a receiver appointed at the instance or request of Landlord) to take possession of all or substantially all of the assets of Tenant, or (2) a general assignment by Tenant for the benefit of creditors, or (3) any action taken or suffered by Tenant under any insolvency or bankruptcy act shall constitute a breach of this Lease by Tenant. In such event, Landlord may, at its option, declare this Lease terminated and forfeited by Tenant, and Landlord shall be entitled to immediate possession of the Leased Premises. Upon such notice of termination, this Lease shall terminate immediately and automatically by its own limitation; or

(d) Multiple Defaults. Any three (3) failures by Tenant to observe and perform any provision of this Lease following written notice and the expiration of any applicable cure period during any twelve (12) month period of the term, as such may be extended, shall constitute, at the option of Landlord, a separate and non-curable default.

25.1 Termination and Damages. In the event of any material default and breach of this Lease by Tenant, then in addition to any other remedies available to Landlord herein or at law or in equity, Landlord shall have the immediate option to terminate this Lease and all rights of Tenant hereunder by giving written notice of such intention to terminate. In the event that Landlord shall elect to so terminate this Lease, then Landlord may recover from Tenant:

(a) The worth at the time of award of any unpaid rent which had been earned at the time of such termination; plus

(b) The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss Tenant proves could have been reasonably avoided; plus

(c) 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

(d) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of events would be likely to result therefrom; and

(e) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by the applicable law in the state in which the Leased Premises are located.

25.2 Definition. As used in subsections 25.1(a) and (b) above, the “worth at the time of award” is computed by allowing interest at the rate of ten percent (10%) per annum. As used in subsection 25.1(c) above, the “worth at the time of award” is computed by discounting such amount at the discount rate of the Federal Reserve Bank for the region in which the Complex is located at the time of award plus one percent (1%).

25.3 Personal Property. In the event of any default by Tenant, Landlord shall also have the right and option, with or without terminating this Lease, to do any one or combination of the following:

(a) to reenter the Leased Premises and remove all persons and property from the Leased Premises;

(b) to have all of Tenant’s fixtures, furniture, equipment, improvements, additions, alterations and other personal property remain upon the Leased Premises during the length of any default by Tenant or a lesser period; or

Landlord shall have the sole right to take exclusive possession of such property and to use it, rent, or charge free, until all defaults are cured. If Landlord shall remove property from the Leased Premises, Landlord may, in its sole and absolute discretion, store such property in the Complex, in a public warehouse or elsewhere. All reasonable costs incurred by Landlord under this section, including, without limitation, those for removal and storage (including, without limitation, charges imposed by Landlord for storage within the Complex), shall be at the sole cost of and for the account of Tenant. The rights stated herein are in addition to Landlord’s rights described in Article 17.

(a) In the event of the abandonment of the Leased Premises by Tenant or in the event that Landlord shall elect to reenter as provided in Section 25.3 above, or shall take possession of the Leased Premises pursuant to legal proceeding or pursuant to any notice provided by law, then if Landlord does not elect to terminate this Lease as provided in Section 25.1 above, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession, and Landlord may enforce all its rights and remedies under this Lease, including, without limitation, Landlord’s right from time to time, without terminating this Lease, to either recover all rental as it becomes due or relet the Leased Premises or any part thereof for such term or terms and at such rental or rentals and upon such other terms and conditions as Landlord, in its sole but reasonable discretion, may deem advisable with the right to make alterations and repairs to the Leased Premises. Acts of maintenance or preservation or efforts to relet the Leased Premises or the appointment of a receiver upon initiation of Landlord or other legal proceeding granting Landlord or its agent possession to protect Landlord’s interest under this Lease shall not constitute a termination of Tenant’s right to possession.

(b) In the event that Landlord shall elect to so relet, then rentals received by Landlord from such reletting shall be applied: first, to the payment of any indebtedness other than rent due hereunder from

Tenant to Landlord; second, to the payment of any cost of such reletting; third, to the payment of the cost of any alterations and repairs to the Leased Premises; fourth, to the payment of rent due and unpaid hereunder; and the residue, if any, shall be held by Landlord and applied in payment of future rent as the same may become due and payable hereunder. Should that portion of such rentals received from such reletting during any month, which is applied by the payment of rent hereunder, be less than the rent payable during that month by Tenant hereunder, then Tenant shall pay such deficiency to Landlord immediately upon demand therefor by Landlord. Such deficiency shall be calculated and paid monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs and expenses incurred by Landlord in such reletting or in making such alterations and repairs not covered by the rentals received from such reletting.

(c) No reentry or taking possession of the Leased Premises or any other action under this Section shall be construed as an election to terminate this Lease unless a written notice of such intention be given to Tenant or unless the termination thereof be decreed by a court of competent jurisdiction. Notwithstanding any reletting without termination by Landlord because of any default by Tenant, Landlord may at any time after such reletting elect to terminate this Lease for any such default.

(d) Landlord has 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 right to sublet or assign, subject only to reasonable limitations).

25.5 No Waiver. Efforts by Landlord to mitigate the damages caused by Tenant’s default in this Lease shall not constitute a waiver of Landlord’s right to recover damages hereunder, nor shall Landlord have any obligation to mitigate damages hereunder.

25.6 Curing Defaults. Should Tenant fail to repair, maintain, and/or service the Leased Premises, or any part or contents thereof at any time or times, or perform any other obligations imposed by this Lease or otherwise, then after having given Tenant reasonable notice of the failure or failures and a reasonable opportunity which in no case shall exceed thirty (30) days, to remedy the failure (unless Tenant commenced such remedy within the thirty (30) day period and is diligently proceeding to cure), Landlord may perform or contract for the performance of the repair, maintenance, or other Tenant obligation, and Tenant shall pay Landlord for all out of pocket costs incurred in connection therewith within ten (10) business days of receiving a bill therefor from Landlord.

25.7 Cumulative Remedies. The various rights, options, election powers, and remedies of Landlord contained in this Article and elsewhere in this Lease shall be construed as cumulative and no one of them exclusive of any others or of any legal or equitable remedy which Landlord might otherwise have in the event of breach or default, and the exercise of one right or remedy by Landlord shall not in any way impair its right to any other right or remedy.

26.1 Bankruptcy Events. If at any time during the term of this Lease there shall be filed by or against Tenant in any court pursuant to any statute either of the United States or of any state a petition in bankruptcy or insolvency or for reorganization or for the appointment of a receiver or trustee of all or a portion of Tenant’s property, or if a receiver or trustee takes possession of any of the assets of Tenant, or if the leasehold interest herein passes to a receiver, or if Tenant makes an assignment for the benefit of creditors or petitions for or enters into an arrangement (any of which are referred to herein as “a bankruptcy event”), then the following provisions shall apply:

(a) Assume or Reject. At all events any receiver or trustee in bankruptcy or Tenant as debtor in possession (“debtor”) shall either expressly assume or reject this Lease within the earlier of one hundred twenty (120) days following the filing of a petition in bankruptcy or entry of an “Order for Relief” or such earlier period of time provided by law.

(b) Cure. In the event of an assumption of the Lease by a debtor, receiver or trustee, such debtor, receiver or trustee shall immediately after such assumption (1) cure any default or provide adequate assurances that defaults will be promptly cured; and (2) compensate Landlord for actual pecuniary loss or provide adequate assurances that compensation will be made for actual pecuniary loss; and (3) provide adequate assurance of future performance.

(c) Adequate Assurance. For the purposes of paragraph 26.1(b), adequate assurance of future performance of all obligations under this Lease shall include, but is not limited to:

(1) written assurance that rent and any other consideration due under the Lease shall first be paid before any other of Tenant’s costs of operation of its business in the Leased Premises is paid;

(2) written agreement that assumption of this Lease will not cause a breach of any provision hereof including, but not limited to, any provision relating to use or exclusivity in this or any other Lease, or agreement relating to the Leased Premises, or if such a breach is caused, the debtor, receiver or trustee will indemnify Landlord against such loss (including costs of suit and attorneys’ fees), occasioned by such breach;

(d) Landlord’s Obligation. Where a default exists under the Lease, the party assuming the Lease may not require Landlord to provide services or supplies incidental to the Lease before its assumption by such trustee or debtor, unless Landlord is compensated under the terms of the Lease for such services and supplies provided before the assumption of such Lease.

(e) Assignment. The debtor, receiver, or trustee may assign this Lease only if adequate assurance of future performance by the assignee is provided, whether or not there has been a default under the Lease. Any consideration paid by any assignee in excess of the rental reserved in the Lease shall be the sole property of, and paid to, Landlord. Upon assignment by the debtor or trustee, the obligations of the Lease shall be deemed to have been assumed, and the assignee shall execute an assignment agreement on request of Landlord.

(f) Fair Value. Landlord shall be entitled to the fair market value for the Leased Premises and the services provided by Landlord (but in no event less than the rental reserved in the Lease) subsequent to the commencement of a bankruptcy event.

(g) Reservation of Rights. Landlord specifically reserves any and all remedies available to Landlord in Article 25 hereof or at law or in equity in respect of a bankruptcy event by Tenant to the extent such remedies are permitted by law.

27.1 No Merger. The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work as a merger, and shall, at the option of Landlord, terminate all or any existing subleases or subtenancies, or may, at the option of Landlord, operate as an assignment to it of any or all such subleases or subtenancies.

28.1 Limited Liability. Redress for any claim against Landlord under this Lease shall be limited to and enforceable only against and to the extent of Landlord’s interest in the Building, which interest shall include all rents and profits, and all proceeds from a sale, insurance awards, and condemnation awards. The obligations of Landlord shall not be personally binding on, nor shall any resort be had to the private properties of, any of its or its investment manager’s trustees, directors, officers, partners, beneficiaries, members, stockholders, employees, or agents. In no case shall Landlord or Tenant be liable to the other hereunder for any lost profits, damage to business, or any form of special, indirect or consequential damages.

29.1 Attorneys’ Fees. In the event of any litigation or arbitration (if each party in its sole and absolute discretion elects to use arbitration) proceeding between the parties with respect to this Lease, then all costs and expenses, including without limitation, all reasonable professional fees such as appraisers’, accountants’ and attorneys’ fees, incurred by the prevailing party therein shall be paid or reimbursed by the other party. The “prevailing party” means the party determined by the court or arbitrator (if the parties elected to use arbitration) to have most nearly prevailed, even if such party did not prevail in all matters, not necessarily the one in whose favor a judgment is rendered. If, on account of any breach or default by Tenant in Tenant’s obligations under the terms and conditions of this Lease, it shall become necessary or appropriate for Landlord to employ or consult with an attorney or collection agency concerning or to enforce or defend any of Landlord’s rights or remedies arising under this Lease or to collect any sums due from Tenant, Tenant agrees to pay all reasonable costs and fees so incurred by Landlord, including, without limitation, reasonable attorneys’ fees and costs. Should Landlord be named as a defendant or requested or required to appear as a witness or produce any documents in any suit brought by Tenant against any other party or against Tenant in connection with or arising out of Tenant’s occupancy hereunder, Tenant shall pay to Landlord its reasonable costs and expenses incurred in such suit, including without limitation, all reasonable professional fees such as appraisers’, accountants’ and attorneys’ fees. The provisions of this section shall survive the expiration or termination of this Lease.

30.1 Writing. All notices, demands and requests required or permitted to be given or made under any provision of this Lease shall be in writing and shall be given or made by personal service or by mailing same by registered or certified mail, return receipt requested, postage prepaid, or overnight by Fed Ex or reputable courier which provides written evidence of delivery or other means of confirmation of delivery (such as computer confirmation by Fed Ex), addressed to the respective party at the address set forth in Section 1.2 of this Lease or at such other address as the party may from time to time designate, by a written notice sent to the other in the manner aforesaid.

30.2 Effective Date. Any such notice, demand or request (“notice”) shall be deemed given or made on the third day after the date so mailed. Notwithstanding the foregoing, notice given by personal delivery to the party at its address as aforesaid shall be deemed given on the day on which delivery is made or the fax is sent, respectively. Notice given overnight by a reputable courier service which provides written evidence of delivery shall be deemed given on the business day immediately following deposit with the courier service.

30.3 Authorization to Receive. Each person and/or entity whose signature is affixed to this Lease as Tenant or as guarantor of Tenant’s obligations (“obligor”) designates such other obligor its agent for the purpose of receiving any notice pertaining to this Lease or service of process in the event of any litigation or dispute arising from any obligation imposed by this Lease.

31.1 Priority of Encumbrances. This Lease is subordinate to any ground lease, mortgage, deed of trust or any other hypothecation for security now or hereafter placed upon the real property of which the Leased Premises are a part and to any and all advances made on the security thereof and to all renewals, modifications, consolidations, replacements and extensions thereof. If any mortgagee, trustee or ground lessor shall elect to have this Lease prior to the lien of its mortgage, deed of trust or ground lease, and shall give written notice thereof to Tenant, this Lease shall be deemed prior to such mortgage, deed of trust or ground lease, whether this Lease is dated prior or subsequent to the date of said mortgage, deed of trust or ground lease or the date of recording thereof.

31.2 Execution of Documents. Tenant agrees to execute any commercially reasonable documents required to further effectuate such subordination or to make this Lease prior to the lien of any mortgage, deed of trust or ground lease, as the case may be, if requested by Landlord or any lender. It is understood by all parties that Tenant’s failure to execute the subordination documents referred to above may cause Landlord serious financial damage by causing the failure of a financing or sale transaction.

31.3 Attornment. If the holder of any ground lease, mortgage, deed of trust or security described above (or its successor-in-interest), enforces its remedies provided by law or under the pertinent mortgage, deed of trust or security instrument and succeeds to Landlord’s interest in the Leased Premises, Tenant shall, upon request of any person succeeding to the interest of such lender as result of such enforcement, attorn to and recognize as its landlord and become the Tenant of said successor-in-interest without change in the terms or other provisions of this Lease or without the execution of any further instrument by Tenant, provided, however, that said successor-in-interest shall not be (i) bound by any payment of rent for more than thirty (30) days in advance, except prepayment in the nature of security for the performance by Tenant of its obligations under this Lease, (ii) liable for any act or omission of any previous landlord (including Landlord), provided that as successor landlord it shall be obligated to cure any continuing default of the prior landlord of which it has received prior written notice and shall be liable for acts or omissions accruing or arising after such successor’s succession to the position of landlord and commencement of control and management of the Property, (iii) subject to any offset, defense, recoupment or counterclaim that Tenant may have given to any previous landlord (including Landlord), or (iv) liable for any deposit that Tenant may have given to any previous landlord (including Landlord) that has not, as such, been transferred to said successor-in-interest. Within ten (10) days after receipt of request by said successor-in-interest, Tenant shall execute and deliver an instrument or instruments confirming such attornment, including a non-disturbance, attornment and subordination agreement in a form reasonably required by any such successor-in-interest.

31.4 Notice and Right to Cure Default. Tenant agrees to give any mortgagee(s) and/or trust deed holders, by registered mail, a copy of any notice of default served upon Landlord, provided that prior to such notice Tenant has been notified, in writing (by way of Notice of Assignment of Rents and Leases, or otherwise), of the address of such mortgagees and/or trust deed holders. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided for in this Lease or within a reasonable period of time after Landlord’s receipt of such notice of such failure if no specific period of time is provided in this Lease, then the mortgagees and/or trust deed holders shall have an additional thirty (30) days within which to cure such default or, if such default cannot be cured within that time, then such additional time as may be necessary if, within such thirty (30) days, any mortgagee and/or trust deed holder has commenced and is diligently pursuing the remedies necessary to cure such default (including but not limited to commencement of foreclosure proceedings, if necessary to effect such cure), in which event this Lease shall not be terminated while such remedies are being so diligently pursued.

31.5 Non-Disturbance. Landlord has informed Tenant that the Project is currently encumbered by a deed of trust (the “Security Instrument”). At Tenant’s sole cost and expense, Landlord shall request the beneficiary (or its servicer) of the existing Security Instrument that encumbers the Project as of the date hereof to issue its standard subordination, non-disturbance and attornment agreement (“SNDA”), pursuant to which such beneficiary agrees to recognize this Lease in the event of default under such Security Instrument or sale under such Security Instrument, so long as Tenant is not in default hereunder. Additionally, in connection with any future mortgage, deed of trust or ground lease, Landlord shall request the holder of any such instrument that encumbers the Project to issue its standard SNDA, pursuant to which such party agrees to recognize this Lease in the event of any foreclosure of sale under such instrument, so long as Tenant is not in default hereunder. Landlord’s sole obligation under this section is to request such SNDA(s). Tenant is responsible for paying all costs and expenses for such SNDA, including, without limitation, the lender’s or ground lessor’s attorneys’ fees and disbursements. Obtaining any such SNDA is not a condition precedent or subsequent to the Lease, and the failure of such party to issue its SNDA shall not relieve Tenant of any of its obligations under the Lease or constitute a breach or default by Landlord.

32.1 Execution by Tenant. Within ten (10) business days after receipt of written request by Landlord, Tenant shall execute and deliver to Landlord an estoppel certificate acknowledging such facts regarding this Lease as Landlord may reasonably require and to the extent true, including without limitation, that to the extent of Tenant’s current, actual knowledge (i) this Lease is in full force and effect, binding and enforceable in accordance with its terms and unmodified (or if modified, specifying the written modification documents); (ii) no default exists on the part of Landlord or Tenant under this Lease; (iii) there are no events which with the passage of time, or the giving of notice, or both, would create a default under this Lease; (iv) no rent in excess of one month’s rent has been paid in advance; (v) Tenant has not received any written notice of any other sale, assignment, transfer, mortgage or pledge of this Lease or the rent due hereunder; and (vi) Tenant has no defense, setoff, recoupment or counterclaim against Landlord. Any such estoppel certificate may be relied upon by Landlord, any lender and any prospective purchaser of the Building or Complex or any interest therein.

32.2 Financial Statements and Credit Reports. At Landlord’s request, Tenant shall deliver to Landlord a copy, certified by an officer of Tenant as being a true and correct copy, of Tenant’s most recent audited financial statement, or, if unaudited, certified by Tenant’s chief financial officer as being true, complete and correct in all material respects. Tenant hereby authorizes Landlord to obtain one or more credit reports on Tenant at any time, and shall execute such further authorizations as Landlord may reasonably require in order to obtain a credit report.

33.1 Effect of Waiver. The waiver by Landlord or Tenant of any breach of any Lease provision by the other party shall not be deemed to be a waiver of such Lease provision or any subsequent breach of the same or any other term, covenant or condition therein contained. The subsequent acceptance of rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any provision of this Lease, other than the failure of Tenant to pay the particular rental so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such rent. Any failure by Landlord or Tenant to insist upon strict performance by the other of this Lease of any of the terms and provisions of the Lease or any guaranty of this Lease shall not be deemed to be a waiver of any of the terms or provisions of the Lease or such guaranty, and Landlord or Tenant, as the case may be, shall have the right thereafter to insist upon strict performance by the other of any and all of them.

33.2 Holding Over. Tenant shall pay Landlord for each day Tenant retains possession of the Leased Premises or part of them after termination of this Lease by lapse of time or otherwise at the rate (“Holdover Rate”) which shall be One Hundred Fifty Percent (150%) of the greater of (a) the amount of the Minimum Monthly Rent for the last period prior to the date of such termination plus Tenant’s Proportionate Share of Operating Costs, Real Estate Taxes and Insurance; and (b) the then market rental value of the Leased Premises as determined by Landlord assuming a new lease of the Leased Premises of the then usual duration and other terms, in either case, prorated on a daily basis, and also pay all damages sustained by Landlord by reason of such retention. If Landlord gives notice to Tenant of Landlord’s election to such effect, such holding over shall constitute renewal of this Lease for a period from month to month at the Holdover Rate, but if the Landlord does not so elect, no such renewal shall result notwithstanding acceptance by Landlord of any sums due hereunder after such termination; and instead, a tenancy at sufferance at the Holdover Rate shall be deemed to have been created. In any event, no provision of this Section 33.2 shall be deemed to waive Landlord’s right of reentry or any other right under this Lease or at law. Additionally, in the event that upon termination of the Lease, Tenant has not fulfilled its obligation with respect to repairs and cleanup of the Leased Premises or any other Tenant obligations as set forth in this Lease, then Landlord shall have the right to perform any such obligations as it deems necessary at Tenant’s sole cost and expense, and any time required by Landlord to complete such obligations shall be considered a period of holding over and the terms of this section shall apply.

33.3 Binding Effect. The covenants and conditions herein contained shall, subject to the provisions as to assignment, apply to and bind the heirs, successors, executors, administrators and assigns of all of the parties hereto; and all of the parties hereto shall be jointly and severally liable hereunder.

33.4 Time of the Essence. Time is of the essence of this Lease with respect to each and every article, section and subsection hereof.

33.5 Release of Landlord. If, during the term of this Lease, Landlord shall sell its interest in the Building or Complex of which the Leased Premises form a part, or the Leased Premises, then from and after the effective date of the sale or conveyance, Landlord shall be released and discharged from any and all obligations and responsibilities under this Lease, except those already accrued.

33.6 Rules and Regulations. Landlord or such other person(s) as Landlord may appoint shall have the exclusive control and management of the Common Areas and Building and shall have the right, from time to time, to establish, modify, amend and enforce reasonable rules and regulations with respect thereto; provided, however if any future modification, amendment or supplement to the Rules or Regulations are in conflict with any term, covenant or condition of this Lease, then this Lease shall prevail. Tenant agrees to abide by and conform to all such rules and regulations, and to cause its employees, suppliers, shippers, customers, and invitees to so abide and conform. Landlord shall not be responsible to Tenant for the non-compliance with said rules and regulations by other tenants of the Building or Complex.

33.7 Transfer to Purchaser. If any security be given by Tenant to secure the faithful performance of all or any of the covenants of this Lease on the part of Tenant, Landlord may transfer and/or deliver the security, as such, to the purchaser of the reversion, in the event that the reversion be sold, and thereupon Landlord shall be discharged from any further liability in reference thereto.

33.8 Late Charges. Tenant acknowledges that late payment by Tenant to Landlord of rent or any other payment due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such costs being extremely difficult and impractical to fix. Such costs include, without limitation, processing and accounting charges, and late charges that may be imposed on Landlord by the terms of any encumbrance and note secured by any encumbrance covering the Leased Premises. Therefore, if any installment of rent, or any other payment due hereunder from Tenant is not received by Landlord when due, Tenant shall pay to Landlord an additional sum of five percent (5%) of such rent or other charge as a late charge; provided, however, that Tenant shall be entitled to one notice of late payment and a five (5) business day cure period in each twelve (12) month period before any such late charge accrues. The parties agree that this late charge represents a fair and reasonable estimate of the cost that Landlord will incur by reason of late payment by Tenant. Acceptance of any late charge shall not constitute a waiver of Tenant default with respect to the overdue amount, or prevent Landlord from exercising any other rights or remedies available to Landlord

33.9 Interest. Any amount owed by Tenant to Landlord which is not paid within ten (10) days when due shall bear interest at the lesser of ten percent (10%) per annum or the maximum rate of interest permitted to be contracted for by law. However, interest shall not be payable on late charges to be paid by Tenant under this Lease. The payment of interest on such amounts shall not excuse or cure any default by Tenant under this Lease.

33.10 Authorization to Execute. If Tenant is a corporation, limited liability company, partnership or other entity, each individual executing this Lease on behalf of said organization represents and warrants that he is duly authorized to execute and deliver this Lease on behalf of said organization in accordance with a duly adopted resolution or other applicable authorization of said organization, and that this Lease is binding upon said organization in accordance with its terms. Further, if requested by Landlord, Tenant shall, within thirty (30) days after such request, deliver to Landlord a certified copy of a resolution or other applicable authorization of said organization authorizing or ratifying the execution of this Lease.

33.11 Captions. The captions of this Lease are for convenience only and are not a part of this Lease and do not in any way limit or amplify the terms and provisions of this Lease.

33.12 Number and Gender. Whenever the singular number is used in this Lease and when required by the context, the same shall include the plural, the plural shall include the singular, and the masculine gender shall include the feminine and neuter genders, and the word “person” shall include corporation, firm or association. If there be more than one Tenant, the obligations imposed under this Lease upon Tenant shall be joint and several.

33.13 Modifications. This instrument contains all of the agreements, conditions and representations made between the parties to this Lease and may not be modified orally or in any other manner than by an agreement in writing signed by all of the parties to this Lease.

33.14 Payments. Except as otherwise expressly stated, each payment required to be made by Tenant shall be in addition to and not in substitution for other payments to be made by Tenant.

33.15 Severability. The invalidity of any provision of this Lease, as determined by a court of competent jurisdiction, shall in no way affect the validity of any other provision hereof.

33.16 No Offer. The preparation and submission of a draft of this Lease by either party to the other shall not constitute an offer, nor shall either party be bound to any terms of this Lease or the entirety of the Lease itself until both parties have fully executed a final document and an original signature document has been received by both parties. Until such time as described in the previous sentence, either party is free to terminate negotiations with no obligation to the other.

33.17 Light, Air and View. No diminution of light, air, or view by any structure which may hereafter be erected (whether or not by Landlord) shall entitle Tenant to any reduction of Rent, result in any liability of Landlord to Tenant, or in any other way affect this Lease or Tenant’s obligations hereunder.

33.18 Public Transportation Information. If and to the extent required by applicable law, Tenant shall establish and maintain during the Term hereof a program to encourage maximum use of public transportation by personnel of Tenant employed on the Leased Premises, including without limitation the distribution to such employees of written materials explaining the convenience and availability of public transportation facilities adjacent or proximate to the Complex, staggering working hours of employees, and encouraging use of such facilities, all at Tenant’s sole reasonable cost and expense. Tenant shall comply with all requirements of any local transportation management ordinance.

33.19 Joint and Several Liability. Should Tenant consist of more than one person or entity, they shall be jointly and severally liable on this Lease.

33.20 Survival of Obligations. All obligations of Tenant which may accrue or arise during the term of this Lease or as a result of any act or omission of Tenant during said term shall, to the extent they have not been fully performed, satisfied or discharged, survive the expiration or termination of this Lease.

33.21 Real Estate Brokers. Landlord and Tenant each represents and warrants to the other party that it has not authorized, retained or employed, or acted by implication to authorize, retain or employ, any real estate broker or salesman to act for it or on its behalf in connection with this Lease so as to cause the other party to be responsible for the payment of a brokerage commission, except for the Broker(s) identified in Article 1. Landlord and Tenant shall each indemnify, defend and hold the other party harmless from and against any and all claims by any real estate broker or salesman (other than the Brokers) whom the indemnifying party authorized, retained or employed, or acted by implication to authorize, retain or employ, to act for the indemnifying party in connection with this Lease.

33.22 Waiver of California Code Sections. In this Lease, numerous provisions have been negotiated by the parties, some of which provisions are covered by statute. Whenever a provision of this Lease and a provision of any statute or other law cover the same matter, the provisions of this Lease shall control. Therefore, Tenant waives (for itself and all persons claiming under Tenant) the provisions of Civil Code Sections 1932(2) and 1933(4) with respect to the destruction of the Leased Premises; Civil Code Sections 1941 and 1942 with respect to Landlord’s repair duties and Tenant’s right to repair; Code of Civil Procedure Section 1265.130, allowing either party to petition the Superior Court to terminate this Lease in the event of a partial taking of the Leased Premises by condemnation as herein defined; and any right of redemption or reinstatement of Tenant under any present or future case law or statutory provision (including Code of Civil Procedure Sections 473 and 1179 and Civil Code Section 3275) in the event Tenant is dispossessed from the Leased Premises for any reason. This waiver applies to future statutes enacted in addition to or in substitution for the statutes specified herein.

33.23 Quiet Enjoyment. So long as Tenant pays all of the Minimum Monthly Rent, all additional rent and other sums and charges under the Lease and otherwise performs all of its obligations in the Lease, Tenant shall have the right to possession and quiet enjoyment of the Leased Premises free from any unreasonable disturbance or interference, subject to the terms and provisions of the Lease. Landlord represents and warrants that it has the full right and power to execute and perform this Lease and to grant the estate demised herein.

33.24 Representation. Neither Tenant nor any of its constituent partners, managers, members or shareholders, nor any beneficial owner of Tenant or of any such partner, manager, member or shareholder (a) is listed on the Specially Designated Nationals and Blocked Persons List maintained by the Office of Foreign Asset Control, Department of the Treasury (“OFAC”) pursuant to the Executive Order No. 13224, 66 Fed. Reg. 49079 (Sept. 25, 2001) (“Order”); (b) is listed on any other list of terrorists or terrorist organizations maintained pursuant to the Order, the rules and regulations of OFAC or any other applicable requirements contained in any enabling legislation or other Executive Orders in respect of the Order (the Order and such other rules, regulations, legislation or orders are collectively called the “Orders”); (c) is engaged in activities prohibited in the Orders; or (d) has been convicted, pleaded nolo contendere, indicted, arraigned or custodially detained on charges involving money laundering or predicate crimes to money laundering.

33.25 Guaranty. Notwithstanding anything to the contrary contained herein, this Lease is expressly conditioned upon the full execution and delivery of the a guaranty in the form attached hereto as Exhibit G by the entity identified as the Guarantor therein.

33.26 Counterparts. This Lease may be executed in one or more counterparts, including any facsimile or other electronic version of same, each of which shall be deemed an original, but all of which when taken together shall constitute one agreement. Any facsimile or other electronic signature shall constitute a valid and binding method for executing this Lease. Executed counterparts of this Lease exchanged by facsimile transmission or other electronic means shall be fully enforceable.

1. Definitions and Conflict. All capitalized terms referred to in this Exhibit shall have the same meaning as provided in the Lease, except as expressly provided to the contrary in this Exhibit. In case of any conflict between any term or provision of the Lease and any exhibits attached thereto and this Exhibit, this Exhibit shall control.

2. Option to Extend and Rent During the Extended Period: Tenant shall have one option to extend the initial Term of the Lease for a period of five (5) years (the period shall be referred to as the “Extension Period”) by giving written notice of exercise of such option (“Extension Option Notice”) at least three hundred sixty-five (365) days, but not more one year and ninety days prior to the expiration of the initial Term of the Lease. If Tenant is in default under any term or provision of the Lease (following written notice and the expiration of any applicable cure period) on the date of giving an Extension Option Notice, or if Tenant is in default under any term or provision of the Lease (following written notice and the expiration of any applicable cure period) on the date of the applicable Extension Period is to commence, the Extension Period at the option of Landlord shall not commence and the Lease shall expire at the end of initial Term. The Extension Period shall be upon all of the terms and provisions of the Lease, except that (i) the Minimum Monthly Rent during such Extension Period shall be one hundred percent (100%) of then Fair Market Rent (as defined below) (ii) any work, allowance, free rent, or concession provided by Landlord in connection with the commencement of the initial Term shall not apply; and (iii) Tenant shall not have any additional option to extend.

2.1 Fair Market Rent. The term “Fair Market Rent” for purposes of determining Minimum Monthly Rent during the Extension Period shall mean the minimum monthly rent generally applicable to full service office leases at first class buildings of comparable size, age, quality of the Building and Leased Premises in the South San Francisco, California area projected as of the first day of the Extension Period by giving due consideration for the quality of the Building and improvements therein (including the quality of the then existing improvements in the Leased Premises), the quality of the credit of the tenants, tenant improvement allowance, rent credits, or abated rent then being offered, for a term comparable to the Extension Period at the time the commencement of the Extension Period is scheduled to commence, without any deduction for commissions whether or not incurred by Landlord, and otherwise subject to the terms and conditions of this Lease that will be applicable during the Extension Period.

2.2 Procedure to Determine Fair Market Rent. Landlord shall notify Tenant in writing of Landlord’s determination of the Fair Market Rent (“Landlord’s FMR”) within thirty (30) days after receipt of the Extension Option Notice. Within thirty (30) days after receipt of such written notice of Landlord’s FMR, Tenant shall have the right either to: (i) accept Landlord’s FMR, or (ii) elect to have the Fair Market Rent determined in accordance with the appraisal procedure set forth below. The failure of Tenant to provide written notice of its election under the preceding sentence shall be deemed an acceptance of Landlord’s FMR. The election (or deemed election ) by Tenant under this section shall be non-revocable and binding on the parties.

2.3 Appraisers. If Tenant has elected to have the Fair Market Rent determined by an appraisal, then within ten (10) business days after receipt of Tenant’s written notice of such an election, each party, by giving written notice to the other party, shall appoint a broker to render a written opinion of the Fair Market Rent for the Extension Period. Each broker must be a real estate broker licensed in the State where the Building is located for at least five years and with at least five years experience in the appraisal of rental rates of leases or in the leasing of space in office buildings in the area in which the Building is located and otherwise unaffiliated with either Landlord or Tenant. The two brokers shall render their written opinion of the Fair Market Rent for the Extension Period to Landlord and Tenant within thirty (30) days after the appointment of

the second broker. If the Fair Market Rent of each broker is within three percent (3%) of each other, then the average of the two appraisals of Fair Market Rent shall be the Fair Market Rent for the Extension Period. If one party does not appoint its broker as provided above, then the one appointed shall determine the Fair Market Rent. The Fair Market Rent so determined under this section shall be binding on Landlord and Tenant.

2.4 Third Appraiser. If the Fair Market Rent determined by the brokers is more than three percent (3%) apart, then the two brokers shall pick a third broker within ten (10) business days after the two brokers have rendered their opinions of Fair Market Rent as provided above. If the two brokers are unable to agree on the third broker within said ten (10) business day period, Landlord and Tenant shall mutually agree on the third broker within ten (10) business days thereafter. If the parties do not agree on a third qualified broker within ten (10) business days, then at the request of either Landlord or Tenant, such third broker shall be promptly appointed by the then Presiding Judge of the Superior Court of the State of California for the County where the Building is located. The third broker shall be a person who has not previously acted in such capacity for either party and must meet the qualifications stated above.

2.5 Impartial Appraisal. Within thirty (30) days after its appointment, the third broker (the “Third Party”), shall render its written opinion by selecting the Fair Market Rent made Landlord’s or Tenant’s broker to be the Fair Market Rent for the Extension Period. The Third Party may not offer any different opinion or recommendation of Fair Market Rent. The Fair Market Rent determined in accordance with the foregoing procedure shall be binding on the parties.

2.6 Appraisal Costs. Each party shall bear the cost of its own appraiser and one-half (1/2) the cost of the third appraiser.

2.7 Acknowledgment of Rent. After the Fair Market Rent for the Extension Period has been established in accordance with the foregoing procedure, Landlord and Tenant shall promptly execute an amendment to the Lease to reflect the minimum monthly rent for the Extension Period.

3. Right of First Offer Expansion. If Tenant is not in default of any term or provision of the Lease (following written notice and the expiration of any applicable cure period) and has not assigned the Lease or sublet any space covered thereby or agreed to do so in the future (other than pursuant to a Permitted Transfer), and is occupying and actively conducting business in not less than 90 % of the Rentable Area of the Leased Premises, Tenant shall have the one time right only during the Term (the “First Offer Period”), unless Tenant does not exercise its option to extend the Term as provided in Section 2 above in which case the First Offer Period shall expire one year prior to the expiration of the initial Term, not any extended term, of the Lease to expand into the suite shown on Schedule 1 hereto (the “Expansion Space”) solely in accordance with the terms of this Section 3 and its subsections. The Expansion Space contains approximately 5,275 square feet of Rentable Area. Tenant’s right of first offer to lease the Expansion Space may be referred to as the “First Offer Right.”; The First Offer Right shall not be applicable to (i) a renewal, expansion, assignment or sublease of any lease or any new lease with any existing tenant or any partner, attorney, employee, agent or affiliate of any existing tenant for space in any portion of the Expansion Space, or (ii) any expansion options or similar rights granted to any other existing tenant as of the date of this Lease in the Building pursuant to its lease.

3.1 Process. During First Offer Period, if Tenant wants to lease additional space in the Expansion Space, Tenant shall notify Landlord of Tenant desire to lease all of the Expansion Space (“Tenant’s Expansion Request”). If Tenant does not provide Tenant’s Expansion Request during the First Offer Period or if Landlord determines in its good faith discretion that space is not available or will not be available during the First Offer Period, then First Offer Right under Section 3 and its subsections automatically will terminate and be of no further force or effect. If Landlord determines in its good faith discretion that the Expansion Space is available for lease or will be available for lease within the following six months after Landlord’s receipt of Tenant’s Expansion Request, Landlord will propose such space to Tenant for lease at a rental rate and other terms and conditions acceptable to Landlord in its sole and absolute discretion (“Landlord’s Expansion

Proposal”). No court, arbitrator, mediator, appraiser or other third party shall have the right to determine the terms and conditions for any lease terms in Landlord’s Expansion Proposal. Tenant shall have five (5) business days within which to agree to lease such Expansion Space on the terms set forth in Landlord’s Expansion Proposal or to reject such proposal. The failure of Tenant to provide unconditional and irrevocable written notice of acceptance shall be deemed a rejection. If Tenant provides written notice of acceptance of Landlord’s Expansion Proposal but makes any change in the terms for the lease of the Expansion Space contained in the Landlord’s Expansion Proposal, then it shall be deemed a rejection of Landlord’s Expansion Proposal.

3.2 Effect of Non-Acceptance. If Tenant does not accept the offer to lease all of the Expansion Space pursuant to Landlord’s Expansion Proposal, Landlord shall be free to lease all or any portion of the Expansion Space to any other party on such terms proposed in Landlord’s Expansion Proposal, or on any other terms which may be different than the terms in Landlord’s Expansion Proposal, in which case Tenant’s First Offer shall automatically lapse and be of no further force and effect, notwithstanding that Landlord may or may not actually lease all or any portion of the Expansion Space to other parties. Tenant acknowledge that Landlord shall have the right to lease portions of the Expansion Space to different parties, but that Tenant’s expansion right under Section 3 and its subsections only pertains to all of the Expansion Space.

3.3 Election to Expand. If Tenant accepts Landlord Expansion Proposal as provided above, then the parties shall enter into an amendment of the Lease to include such Expansion Space on the terms set forth in Landlord’s Proposal Notice within fifteen (15) days after Landlord’s receipt of Tenant’s acceptance; however, the failure of Tenant to execute such amendment within said time period shall not relieve Tenant of its obligation to lease the Expansion Space on the terms set forth in Landlord’s Proposal Notice.

3.4 Personal Option. The Right of First Offer to lease the Expansion Space is personal to the original Tenant signing the Lease and any successor pursuant to a Permitted Transfer, but may not be assigned or transferred to or exercised by any assignee, sublessee or transferee under a Transfer.

This Guaranty of Lease is made by Patient Services, Inc., a Virginia corporation (“Guarantor”) for the benefit of DWF III Gateway, LLC, a Delaware limited liability company (“Landlord”), and its successors and assigns, with respect to the following facts:

A. Landlord and Accesia, Inc., a Virginia corporation (the “Tenant”), entered into that certain Office Lease dated as of November 13, 2012 (the “Lease”) for the lease by Tenant of space located at 701 Gateway Boulevard, Suite 200, South San Francisco, California, California, as more particularly described in the Lease.

B. As a material inducement for Landlord to enter into the Lease with Tenant, Guarantor has agreed to provide this Guaranty of Lease to Landlord.

NOW, THEREFORE, for in consideration of the foregoing and the mutual covenants hereinafter contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Guaranty. Guarantor hereby unconditionally and without limitation guarantees payment and performance by Tenant of its obligations under the Lease following notice and any applicable cure period. Guarantor hereby covenants and agrees with Landlord, notwithstanding any modification or alteration of the Lease, (i) to make the due and punctual payment of all rent, additional rent, reimbursements, late charges, interest and other sums and charges expressed to be payable under the Lease during the term thereof and all renewals thereof, (ii) to effect prompt and complete performance of each and every term, covenant, condition and provision in the Lease on the part of Tenant to be kept, observed and performed during the period of the term and any renewals thereof; and (iii) to protect, defend, indemnify and save harmless Landlord from any loss, costs or damages (including legal fees and expenses for counsel of Landlord’s choice) arising out of any failure to pay the aforesaid rent, monies, charges or indebtedness or the failure to perform any of the terms, covenants, conditions and provisions in the Lease or this Guaranty of Lease. Guarantor hereby acknowledges that it has a copy of and is familiar with each and every document executed and delivered to Landlord by Tenant including, without limitation, the Lease.

2. Rights. In the event of any breach, default or failure of Tenant to pay any sum or perform any obligation under the Lease, Guarantor shall immediately pay to Landlord any and all such amounts as may be due and owing from Tenant to Landlord by reason of Tenant’s failure to perform. Landlord shall have the right to enforce this indemnity regardless of the acceptance of additional security from Tenant and regardless of the release or discharge of Tenant by Landlord or by others, or by operation of any law. In addition to the obligations of Guarantor set forth above, Guarantor agrees to pay to Landlord any and all damages and expenses incurred by Landlord as a direct and proximate result of Tenant’s failure to perform. Guarantor further agrees to pay to Landlord interest on any and all sums due and owing Landlord, by reason of Tenant’s failure to pay same, at the rate per annum provided in the Lease.

3. Waivers. Guarantor hereby expressly waives any right of setoff or compensation against amounts due under this Guaranty of Lease and waives notice of the acceptance of this indemnity and all notice of nonperformance, nonpayment or non-observance on the part of Tenant of the terms, covenants, conditions and provisions of the Lease. In addition, Guarantor hereby waives all rights and defenses to:

(a) All defenses by reason of any disability of Tenant, or based on the termination of Tenant’s liability from any cause, or on any statute of limitations respecting obligations accruing under the Lease or this Guaranty of Lease;

(b) Any and all rights it may have now or in the future to require or demand that Landlord pursue any right or remedy Landlord may have against Tenant or any other third party;

(c) Any and all rights it may have to enforce any remedies available to the Landlord now or in the future, against Tenant;

(d) Any and all rights to participate in any security held by Landlord now or in the future;

(e) The right to require Landlord to (i) proceed against Tenant, (ii) proceed against or exhaust any security which Landlord now holds or may hold in the future from Tenant, (iii) pursue any other right or remedy available to Landlord, or (iv) have the property of Tenant first applied to the discharge of any of the obligations under this Guaranty of Lease;

(f) Until all of Tenant’s obligations under the Lease to Landlord have been discharged in full, any right of subrogation it now has, or may hereafter have, against Tenant;

(g) Any defense as a surety, including, without limitation, Guarantor waives the benefits of the provisions of sections 2809, 2810, 2819, 2825, 2845, 2846, 2849, and 2850 of the California Civil Code and any similar or analogous statutes of California or any other jurisdiction;

(h) Any duty or obligation of Landlord to disclose to Guarantor any facts Landlord may now or hereafter know about Tenant, regardless or whether Landlord has reason to believe that any such facts materially increase the risk beyond that which Guarantor intends to assume or has reason to believe that such facts are unknown to Guarantor or has a reasonable opportunity to communicate such facts to Guarantor, it being understood and agreed that Guarantor is fully responsible for being and keeping informed of the financial condition of Tenant and of any and all circumstances bearing on the risk of nonperformance of any obligation guaranteed under this Guaranty of Lease; and

(i) Any defense based upon an election of remedies by Landlord, including any election which destroys or impairs any right of subrogation, reimbursement or contribution which Guarantor may have, or any rights or benefits under any provisions of California law in any way qualifying, conditioning or limiting the obligations of Guarantor based on any steps or procedures that Landlord should take before proceeding against Guarantor.

4. Effect of Modifications, Extensions or Alterations of the Lease. Without limiting the generality of the foregoing, the liability of Guarantor under this Guaranty of Lease shall not be deemed to have been waived, released, discharged, impaired or affected by reason of (a) any waiver or failure to enforce any of the obligations of the Tenant under the Lease, or (b) assignment of the Lease, or the subletting of the leased premises by the Tenant (with or without in each case the consent of the Landlord), or (c) the expiration or other termination of the term, or (d) the release or discharge of the Tenant in any receivership, bankruptcy, winding-up or other creditors’ proceedings or the rejection, disaffirmance or disclaimer of the Lease by any party in any action or proceeding, and shall continue with respect to the periods prior thereto and thereafter, for and with respect to the term originally contemplated and expressed in the Lease or any renewals or extensions thereof. Guarantor further understands and agrees that the obligations of Guarantor under this Guaranty of Lease shall in no way be affected by any extension, modification or alteration of the Lease, or Tenant’s obligation under the Lease and each of its provisions, and any such extension, modification or alteration of the Lease, any and all of which may be done without the prior consent or approval of Guarantor and shall in no way release or discharge Guarantor from any obligations accruing under this Guaranty of Lease. The term “Lease” shall include all amendments, modifications, alterations and extensions of the Lease. The liability of the Guarantor shall not be affected by any repossession of the leased premises by Landlord.

5. Payment and Performance. This Guaranty of Lease shall be one of payment and performance and not of collection.

6. Nature of Guaranty. The liability of any Guarantor hereunder is direct, immediate, absolute, continuing, unconditional, primary and unlimited. Notwithstanding the use of the word “indemnity” or “guaranty” in this Guaranty of Lease and without limiting the foregoing, each Guarantor shall be bound by this Guaranty of Lease in the same manner as though a Guarantor were the Tenant named in the Lease.

7. Successors and Assigns. All of the terms, agreements and conditions of this Guaranty of Lease shall extend to and be binding upon each Guarantor, his heirs, executors, administrators, successors, and assigns, and shall inure to the benefit of and may be enforced by Landlord, its successors and assigns, and the holder of any mortgage to which the Lease may be subject and subordinate from time to time.

8. Assignment by Landlord. Landlord may, without notice, assign this Guaranty of Lease in whole or in part and no assignment or transfer of the Lease shall operate to extinguish or diminish the liability of the any Guarantor hereunder.

9. Subordination. Any indebtedness of the Tenant now or hereafter held by a Guarantor is hereby subordinated to the indebtedness of the Tenant to the Landlord; and any indebtedness of the Tenant to any Guarantor, if the Landlord so requests, shall be collected, enforced and received by Guarantor as trustee for the Landlord on account of the indebtedness of the Tenant to the Landlord without affecting the liability of Guarantor under this Guaranty of Lease.

10. Authority. It is not necessary for the Landlord to inquire into the powers of the Tenant or of the partners or agents acting or purporting to act on its behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder. Guarantor represents and warrants to Landlord that the individual(s) executing this Guaranty of Lease on behalf of Guarantor is duly authorized to execute and deliver this Guaranty of Lease on behalf of such Guarantor in accordance with the governing documents of such Guarantor, and that this Guaranty of Lease is binding upon Guarantor in accordance with its terms.

11. Waiver of Jury Trial. As a further inducement of Landlord to enter into the Lease and in consideration thereof, Landlord and each Guarantor hereby express waive the right to a trial by jury for any action or proceeding brought by either Landlord or any Guarantor against the other on any matter whatsoever arising out of, under, or by virtue of any of the terms, covenants, conditions, provisions or arrangements of the Lease or of this Guaranty of Lease.

12. Bankruptcy. Guarantor shall not, without the prior written consent of Landlord, commence, or join with any other person in commencing, any bankruptcy, reorganization, or insolvency proceeding against Tenant.

Guarantor shall file in any bankruptcy or other proceeding in which the filing of claims is required or permitted by law all claims that Guarantor may have against Tenant relating to any indebtedness of Tenant to Guarantor, and shall will assign to Landlord all rights of Guarantor under these claims. Landlord shall have the sole right to accept or reject any plan proposed in such proceeding and to take any other action that a party filing a claim is entitled to take. In all such cases, whether in administration, bankruptcy, or otherwise, the person or persons authorized to pay such claim shall pay to Landlord the amount payable on such claim and, to the full extent necessary for that purpose, each Guarantor assigns to Landlord all of Guarantor’s rights to any such payments or distributions to which such Guarantor would otherwise be entitled; provided, however, that Guarantor’s obligations under this Guaranty of Lease shall not be satisfied except to the extent that Landlord receives cash by reason of any such payment or distribution. If Landlord receives anything other than cash, the same shall be held as collateral for amounts due under this Guaranty of Lease.

If a claim (“Claim”) is made on Landlord at any time (whether before or after payment or performance in full of any obligation of Guarantor, and whether such claim is asserted in a bankruptcy proceeding or otherwise) for repayment or recovery of any amount or other value received by Landlord (from any source) in payment of, or on account of, any obligation of Guarantor under this Guaranty of Lease, and if Landlord repays such amount, returns value, or otherwise becomes liable for all or part of such Claim by reason of (a) any judgment, decree, or order of any court or administrative body or (b) any settlement or compromise of such Claim, Guarantor shall remain severally liable to Landlord for the amount so repaid or returned or for which Landlord is liable to the same extent as if such payments or value had never been received by Landlord, despite any termination of this Guaranty of Lease or the termination of the Lease or cancellation of any document evidencing any obligation of any Guarantor under this Guaranty of Lease.

13. Attorneys’ Fees and Costs. In the event of any action or proceeding at law or in equity between Landlord and Guarantor (including an action or proceeding between Landlord and the trustee debtor in possession while Guarantor is a debtor in a proceeding under the Bankruptcy Code (Title 11 of the United States Code) or any successor statute to such Code) to enforce any provision of this Guaranty of Lease or to protect or establish any right or remedy of either Landlord or Guarantor hereunder, the unsuccessful party to such action or proceeding shall pay to the prevailing party all costs and expenses, including, without limitation, attorneys’ fees and expenses, incurred in such action or proceeding and in any appeal in connection therewith by such prevailing party, whether or not such action, proceeding or appeal is prosecuted to judgment or other final determination, together with all costs of enforcement and/or collection of any judgment or other relief.

Except as provided in Section 13 above, Guarantor hereby agrees to be responsible for and to pay all costs and expenses, including, without limitation, reasonable attorneys’ fees and expenses incurred by Landlord in connection with the collection of all sums guarantied hereunder and the defense or enforcement of any of Landlord’s rights hereunder, whether or not suit is filed, and whether such collection be from Tenant or from Guarantor.

15. Miscellaneous. Each provision of this Guaranty of Lease shall be enforceable to the extent not prohibited by law. If any provision or its application to any person or circumstance shall be invalid or unenforceable, the remaining provisions, or the application of such provision to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected. This Guaranty of Lease may not be modified or terminated except as expressly provided herein or except by a writing signed by Landlord and a Guarantor. Any such modification or termination made otherwise than as expressly permitted by this paragraph

shall be void. This Guaranty of Lease shall be governed by and interpreted in accordance with the laws of the State of California.

The term “Tenant” whenever used in this Guaranty of Lease refers to and means Tenant under the Lease and also any assignee of the interest of Tenant in the Lease or any subtenant of all or any part of the Premises and their respective successors in interest.

16. Time of the Essence. Time is strictly of the essence under this Guaranty of Lease and any amendment, modification, or revision of this Guaranty of Lease.

17. Cumulative Rights and Remedies. The extent of a Guarantor’s liability and all rights, powers and remedies of Landlord hereunder shall be cumulative and not alternative and such rights, powers and remedies shall be in addition to all rights, powers and remedies given to Landlord by law.
