Upon expiration or termination of the Lease, as it may be extended, Tenant shall not be required to remove any Improvements to the Existing Premises and/or the Expansion Premises to which Landlord has consented. Notwithstanding the

-4-


foregoing, however, upon the expiration or termination of the Lease, as it may be extended, Tenant shall at Tenant153s expense remove all cabling installed in any portion of the Existing Premises, the Expansion Premises and the New Building Premises, except to the extent Landlord in its discretion agrees in writing at the time of such expiration or termination that all or any specified portion of such cabling may be left in place.

6.2. Disbursement of Improvement Allowance. Landlord shall disburse the Improvement Allowance to Tenant in connection with the construction and completion of the Improvements, and in accordance with Landlord153s reasonable and customary disbursement procedures, as set forth herein. The funding of the Improvement Allowance shall be made on a monthly basis or at other convenient intervals mutually approved by Landlord and Tenant, and in all other respects shall be based on such commercially reasonable disbursement conditions and procedures as Landlord reasonably may prescribe (which conditions may include, without limitation, delivery of invoices, architect153s certificates and/or other evidence reasonably satisfactory to Landlord that expenses have been incurred for the design and construction of alterations and improvements to the Existing Premises and/or Expansion Premises, and delivery of conditional or unconditional lien releases from all parties performing the actual work). Notwithstanding the foregoing, any amount of the Improvement Allowance that has not been allocated or disbursed on or before December 31, 2012, shall revert to Landlord and Tenant shall have no further rights thereto. Landlord shall not charge a supervisory or construction management fee relating to the Improvements, but Landlord shall be permitted to recover from Tenant or deduct from the Improvement Allowance Landlord153s actual out-of-pocket fees paid by Landlord to third party consultants or service providers (including third party project managers) which Landlord determines reasonably necessary to facilitate its review and approval of the Improvements. The Improvement Allowance shall not be used by Tenant for moving or relocation expenses, furniture, fixtures or other personal property, or for exterior improvements or signage. Except as specifically set forth in this Section 6, Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Existing Premises or the Expansion Premises pursuant to this Amendment.

6.3. Delivery; "As-Is". Tenant shall accept the Expansion Premises from Landlord on the Expansion Commencement Date in its then existing, "as-is" condition, and, other than the Improvement Allowance and except as set forth in this Section 6.3, Landlord shall have no obligation to pay for or make any improvements to the Expansion Premises (subject, however, to Landlord153s obligations for maintenance and repair as set forth in the Lease). Landlord hereby represents and warrants to Tenant that in connection with the termination of the Microsemi Lease, Microsemi is required to surrender the Expansion Premises to Landlord clear of all hazardous materials, and with Microsemi153s hazardous materials closure plan approved and signed of on by all applicable governmental agencies.

6.3.1 Condition of Expansion Premises. Within thirty (30) days after the Expansion Commencement Date, Landlord, at no cost to Tenant, shall cause (i) the roof, roof membrane, foundations, structural elements and windows of the Expansion Premises, and (ii) the sprinkler and fire/life safety systems serving the Expansion Premises to be in good working condition. Thereafter, the repair and maintenance obligations of the respective parties with respect to the Expansion Premises shall be governed by the applicable provisions of the Lease, except that Tenant shall have until ninety (90) days after the Expansion Commencement Date to ascertain that all such elements and systems were in good working condition as of the date that was thirty (30) days after the Expansion Commencement Date, and to notify Landlord in writing of any respects in which such elements and systems were not in the required condition, in which event Landlord, at no cost to Tenant, shall be responsible for any maintenance, repair or replacement (as reasonably and mutually determined by Landlord and Tenant) necessary to put the applicable systems in the required condition. Landlord shall provide Tenant with any physical inspection reports in Landlord153s possession covering the Expansion Premises, including any such reports pertaining to the roof and/or mechanical (HVAC) systems. Except as otherwise specifically provided in this Amendment, Tenant shall be solely responsible, at Tenant153s own expense, for any and all tenant improvements and alterations required by Tenant for its occupancy and use of the Expansion Premises.

6.3.2 "Tenant Improvements". Solely for purposes of applying the insurance provisions in Section 10.1 of the Original Lease (specifically including, but not limited to, Section 10.1(e) and (f) and the final sentence of Section 10.1(d)), from and after the Expansion Commencement Date (i) the terms "Tenant Improvements" and "Tenant Improvements constructed by Tenant pursuant to the Workletter" as used in such Section 10.1 shall be construed to include any alterations, additions or improvements constructed in the Expansion Premises by Tenant pursuant to this Amendment, and (ii) the term "Tenant Improvement Allowance" as used therein shall be construed to include the Improvement Allowance. In addition, Tenant153s contractors and subcontractors (in connection with work contracted directly by Tenant and not by Landlord) shall be required to carry (1) Commercial General Liability Insurance in an amount not less than $1,000,000 per occurrence and otherwise in accordance with the requirements of Article 10 of this Lease and such commercial general liability insurance shall name Landlord as an additional insured, and (2) Workers compensation.

7.1. Section 4(b) of the Third Amendment is hereby amended to provide that Tenant shall have two (2) options to further extend the term of the Lease for a period of five (5) years each, and the terms "Extended Term", "Second Extended Term", and "Extended Term Expiration Date" shall be deemed to refer to the then applicable term of the Lease or prior term or option term, as the case may be. All other terms of the Lease relating to Tenant153s right to extend the term of the Lease (including, without limitation, Section 7 of the Fifth Amendment) are superseded by this Section 7.

7.2.

8. Brokers. Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Amendment other than CB Richard Ellis and Cornish & Carey Commercial Newmark Knight Frank (the "Brokers"), and

-6-


that they know of no other real estate broker or agent who is entitled to a commission in connection with this Amendment. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, and costs and expenses (including, without limitation, reasonable attorneys153 fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party153s dealings with any real estate broker or agent, other than the Brokers. Landlord shall be responsible for payment of any brokerage commission due in connection with the Existing Premises, the Expansion Premises and the New Building as set forth in a separate agreement or agreements. The terms of this Section 8 shall survive the expiration or earlier termination of this Amendment.

9. Security Deposit. In connection with Tenant153s lease of the New Building Premises, the security deposit held by Landlord under the Lease shall be increased by an amount equal to two (2) months of minimum monthly rental payable with respect to the last two (2) months of the Extended Term (i.e., $686,898.41 based on the estimated 70,000 rentable square feet in the New Building Premises) (the "New Building Security Deposit").

10. Parking. Tenant153s rights to use the unreserved surface parking areas in the Common Areas, as provided in Section 17.20 of the Original Lease, shall be increased as of the Expansion Premises Commencement Date to include 3.0 automobile parking stalls per 1,000 rentable square feet of the Expansion Premises.

Commencing (i) on the Expansion Commencement Date, Tenant shall have the right throughout the remainder of the Term, as extended, to designate up to ten (10) parking spaces for Tenant153s visitor parking for the Expansion Premises, and (ii) on the New Building Commencement Date, Tenant shall have the right through the remainder of the Term, as extended, to designate up to five (5) parking spaces for Tenant153s visitor parking for the New Building Premises, which designated spaces shall be located as mutually agreed upon by Landlord and Tenant, and may be changed by Tenant from time to time (at Tenant153s expense for any restriping or re-designation of spaces). As provided in Section 17.20 of the Original Lease, there shall be no cost or charge to Tenant for the nonexclusive use of parking spaces in the Center by Tenant and its employees and invitees.

11. Transportation Management. Tenant shall fully comply with all present or future programs mandated by the City of Mountain View intended to manage parking, transportation or traffic in and around the Project and/or the Building, and in connection therewith, Tenant shall take responsible action for the transportation planning and management of all employees located at the Premises by working directly with Landlord, any governmental transportation management organization or any other transportation-related committees or entities.

-7-


14. Signage. In connection with Tenant153s improvement and occupancy of the Expansion Premises and the New Building Premises, Tenant shall have the right to install building signage (including building "eyebrow" signage) and additional monument signage substantially consistent with the size, quality and nature of existing signage on buildings occupied by Tenant, subject to (i) Landlord153s prior approval as to location, size, design and composition of such signage (which approval shall not be unreasonably withheld, conditioned or delayed), (ii) Landlord153s established sign criteria or signage program for the Center, consistent with other tenant signage programs in the Center, (iii) all restrictions and requirements imposed by applicable law and/or by applicable governmental authorities, and (iv) any additional restrictions and requirements set forth in the Lease regarding signage.

15. Environmental Conditions. Not later than thirty (30) days after the Reference Date, Landlord shall provide to Tenant copies of all third-party studies and reports, if any, in Landlord153s possession regarding the environmental condition of the Expansion Premises and that portion of the Project upon which the New Building shall be constructed, as set forth in Section 9.6(b)(xi) of the Original Lease. If Landlord does not have in its possession studies or reports for the Expansion Premises or that portion of the Project upon which the New Building will be constructed, Landlord shall so notify Tenant in writing within such thirty (30)- day period. Landlord acknowledges that its indemnification obligations under Section 9.6(c) of the Original Lease shall be effective (i) with respect to the Expansion Premises from and after the Expansion Commencement Date (but shall be inapplicable to matters arising as a result of Tenant153s actions in the Expansion Premises during the term of the LinkedIn Sublease); and (ii) with respect to New Building and that portion of the Project upon which the New Building will be constructed from and after the New Building Commencement Date.

16. Absence of Certain Encumbrances. Reaffirming and updating the representation contained in the final sentence of Section 15.1 of the Original Lease, Landlord represents and warrants to Tenant that as of the Reference Date, neither the Premises nor the Center nor the Expansion Premises nor that portion of the Project upon which the New Building will be constructed is subject to any existing ground lease, mortgage, deed of trust, sale/leaseback transaction or any other hypothecation for security.

17. Damage and Destruction. From and after the Reference Date, the provisions of Section 13.1(a) of the Original Lease hereby is revised to state in its entirety as follows:

(a) If the Premises or any portion of the Building or Common Areas of the Center reasonably necessary for Tenant153s access to or use and occupancy of the Premises is damaged or destroyed in whole or in any substantial part during the term of this Lease, Landlord shall obtain from Landlord153s architect, as soon as practicable (and in all events within forty-five (45) days) following the damage or destruction, (i) the architect153s reasonable, good faith estimate of the time within which repair and restoration of the Premises, Building and Common Areas (if applicable) can reasonably be expected to be completed to the extent necessary to enable Tenant to resume its full business operations in the Premises without material impairment, and (ii) the architect153s reasonable, good faith opinion as to whether repair and restoration to that extent will be permitted under applicable governmental laws, regulations and building codes then in effect (collectively, the "Architect153s Estimate"). If the damage or destruction materially impairs Tenant153s ability to conduct its business operations in the Premises, and if either (A) the estimated repair time specified in the Architect153s Estimate exceeds nine (9) months (or, in the case of an occurrence during the final year of the term of this Lease, ninety (90) days), or (B) the Architect153s Estimate states that repair and restoration of the affected areas to the extent necessary to enable Tenant to resume its full business operations in the Premises without material impairment will not

-8-


be permitted under applicable governmental laws, regulations and building codes then in effect, then in either such event either Landlord or Tenant may terminate this Lease as of the date of the occurrence by giving written notice to the other party within thirty (30) days after the date of the occurrence or fifteen (15) days after delivery of the Architect153s Estimate, whichever is later. In addition, Landlord shall have a similar termination right if the damage or destruction arises from a risk that is not required to be insured against (and is not actually insured against) by Landlord under this Lease and if Landlord153s architect reasonably estimates that the uninsured cost to restore the portions of the Premises and Building for which Landlord is responsible to the condition required above would exceed five percent (5%) of the then applicable replacement cost of the entire Premises; provided, however, that if, within thirty (30) days after the date of Landlord153s election to terminate, Tenant elects by written notice to Landlord to pay the cost of the restoration in excess of the five percent (5%) cap and provides Landlord with reasonable evidence of its ability to do so, Landlord153s termination election shall be deemed rescinded, the parties shall proceed as otherwise provided in this paragraph and this Lease shall continue in full force and effect. If the circumstances creating a termination right under the parties preceding two sentences do not exist, or if such circumstances exist but neither party timely exercises any applicable termination right, then this Lease shall remain in full force and effect and (x) Landlord, as to the Common Areas of the Center and as to the shell of the Building and the alterations, additions and improvements that Landlord is required to insure under Section 10.1(d) above, and (y) Tenant, as to the alterations, additions and improvements that Tenant is required to insure under Section 10.1 (e) above, shall respectively commence and complete, with all due diligence and as promptly as is reasonably practicable under the conditions then existing, the repair and restoration of such respective portions of the Property and Premises to a condition substantially comparable to that which existed immediately prior to the damage or destruction; provided, however, that Tenant in its discretion may elect not to repair, rebuild or replace any or all of the items which would otherwise be Tenant153s responsibility under clause (y) of this sentence to the extent such items were constructed or installed at Tenant153s sole expense and without any use of funds from the Tenant Improvement Allowance. Notwithstanding anything to the contrary contained in the foregoing provisions of this paragraph, if Landlord is required to repair and restore any part of the Premises, Building and/or Common Areas pursuant to this paragraph (a) and such repair and restoration has not been substantially completed (i.e., completed to the extent necessary to enable Tenant to resume its full business operations in the Premises without material impairment) within one (1) year after the date of the casualty or other event requiring such repair or restoration, then Tenant in its discretion may (but shall not be obligated to) terminate this Lease by giving written notice of such termination to Landlord at any time after expiration of such one- year period and prior to Landlord153s substantial completion of the required repair or restoration; provided, however, that such termination shall not be effective if Landlord thereafter substantially completes such repair and restoration within thirty (30) days after receipt of Tenant153s notice of termination.

18. Conditions Precedent. This Amendment is conditioned upon the execution and delivery by the proper parties thereto of (i) a written agreement terminating the Microsemi Lease ("Microsemi Lease Termination Agreement"); (ii) a written agreement terminating the LinkedIn Sublease (including Landlord153s written consent thereto ("LinkedIn Sublease Termination Agreement"), and (iii) the Temporary Space Sublease (collectively the "Related Agreements"). If, for any reason whatsoever, each of the Related Agreements is not fully executed and delivered by all parties by December 31, 2011, then this Amendment with respect to both the Expansion Premises and the New Building Premises shall be deemed null and void and of no further force and effect, and the Existing Lease shall remain unmodified and in full force and effect.

At Landlord153s sole cost and expense, and without deduction from the Tenant Improvement Allowance, Landlord shall construct the base, shell, and core of the Building substantially in accordance with the plans and specifications referenced in Schedule B-2 to this Workletter (the "New Building Plans"). Landlord reserves the right to modify the New Building Plans as reasonably deemed necessary by Landlord (provided, however, that if any such modification causes any actual delay in the substantial completion [as defined below] of the Tenant Improvements beyond March 1, 2013, such modification shall be deemed a Landlord Delay), or as required to comply with applicable laws. Following the substantial completion of the Warm Shell Work (or, to the extent elected by Landlord, concurrent with the Warm Shell Work), Landlord shall construct the Tenant Improvements in the Building, at Tenant153s cost, subject to (but not limited by) the Tenant Improvement Allowance, and otherwise in accordance with the terms of this Workletter.

(b) Approved Plans and Working Drawings for Tenant Improvements. Not later than April 16, 2012, Landlord153s Architect shall prepare, in conjunction with Tenant, to the extent required, preliminary plans (the "Landlord153s Preliminary Plan") in order to allow for the construction by Landlord of the Tenant Improvements. Landlord shall submit the Landlord153s Preliminary Plan to Tenant for Tenant153s approval and information. Within seven (7) business days after Tenant has received Landlord153s Preliminary Plan, Tenant shall either approve Landlord153s Preliminary Plan or set forth in writing with particularity any changes necessary to bring the Preliminary Plan into a form which will be reasonably acceptable to Tenant. In the event the parties cannot reach agreement and resolve all disputed matters relating to the Landlord153s Preliminary Plan, representatives of both parties shall promptly make themselves available to discuss and resolve any such disputed matters, and Landlord153s Preliminary Plan shall promptly be revised by Landlord to incorporate any agreed upon changes. In the event the parties cannot reach agreement and resolve all disputed matters relating to the Landlord153s Preliminary Plan, any delay shall be an Unavoidable Delay. Within seven (7) days after the parties have approved Landlord153s Preliminary Plan, Landlord shall prepare or cause to be prepared (assuming timely delivery by Tenant of all information and decisions reasonably required to be furnished or made by Tenant in order to permit preparation of Landlord153s Final Working Drawings, and subject to Tenant Delays and Unavoidable Delays), final detailed working drawings and specifications for the Tenant Improvements constituting Tenant Improvements, including (as applicable) structural, fire protection, life safety, mechanical, electrical and plumbing working drawings, and final architectural drawings (collectively, "Landlord153s Final Working Drawings"). Landlord153s Final Working Drawings shall be based on and consistent with Landlord153s Preliminary Plan in all material respects (except as otherwise mutually approved by the parties in their respective discretion). Within seven (7) days after receipt of the Landlord153s Final Working Drawings, Tenant shall promptly and diligently either approve Landlord153s Final Working Drawings or set forth in writing with particularity any changes necessary to bring the aspects of such proposed plans and specifications or Landlord153s Final Working Drawings into a form which will be reasonably acceptable to Tenant. In the event the parties cannot reach agreement and resolve all disputed matters relating to the Landlord153s Final Working Drawings, representatives of both parties shall promptly make themselves available to discuss and resolve any such disputed matters, and the Landlord153s Final Working Drawings shall promptly be revised by Landlord to incorporate any agreed upon changes. In the event the parties

-15-


cannot reach agreement and resolve all disputed matters relating to the Landlord153s Final Working Drawings, any delay shall be an Unavoidable Delay. Notwithstanding any other provisions of this paragraph, if Tenant objects to any aspect of Landlord153s Final Working Drawings (including, but not limited to, any subsequently proposed changes therein from time to time) that is (i) materially consistent with the Landlord153s Preliminary Plan, (ii) necessitated by applicable law or as a condition of any governmental or other third-party approvals or consents that are required to be obtained in connection with Tenant Improvements, or (iii) that is required as a result of unanticipated conditions encountered in the course of construction of Tenant Improvements, then any delays in the completion of the Landlord TI Work resulting from such objection or Landlord153s Final Working Drawings resulting from such objection, shall be a Tenant Delay.

(c) Construction of Tenant Improvements. Following completion of Landlord153s Final Working Drawings as approved by Landlord and Tenant, and finalization of the Contract, Landlord shall apply for and use commercially reasonable, good faith efforts to obtain the necessary permits and approvals to allow construction of the Tenant Improvements. Upon receipt of such permits and approvals, Landlord shall construct and complete the Tenant Improvements in accordance with the Landlord153s Approved Plans, subject to Unavoidable Delays and Tenant Delays (if any). Such construction shall be performed in a neat, good and workmanlike manner and shall conform to all applicable laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto in force at the time such work is completed, using new materials and equipment of good quality. Landlord shall use good faith efforts to diligently prosecute the construction of the Tenant Improvements in accordance with the Schedule.

(d) Changes.

(i) If Landlord reasonably determines at any time that changes in any aspect of the Landlord153s Approved Plans are required as a result of applicable law or governmental requirements, or are required at the insistence of any other third party whose approval is required with respect to the Tenant Improvements, or are required as a result of unanticipated conditions encountered in the course of construction, then Landlord shall promptly (A) advise Tenant of such circumstances, and consult with Tenant with regard to the manner in which such changes are instituted, and (B) cause revised Landlord153s Final Working Drawings to be prepared by Landlord153s Architect and submitted to Tenant, for Tenant153s approval, which shall not be unreasonably withheld. Failure of Tenant to deliver to Landlord written notice of disapproval and specification of such required changes within five (5) business days after delivery thereof to Tenant, shall constitute and be deemed to be a Tenant Delay.

(ii) If Tenant at any time desires any changes, alterations or additions to the Landlord153s Approved Plans, Tenant shall submit a detailed written request to Landlord specifying such changes, alterations or additions (a "Tenant Change Request"). Upon receipt of any such request, Landlord shall notify Tenant of (A) whether the matters proposed in the Tenant Change Request are approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed by Landlord), (B) Landlord153s estimate of the number of days of delay, if any, which shall be caused in Tenant Improvements by such Tenant Change Request if implemented (including, without limitation, delays due to the need to obtain any revised plans or drawings and any governmental approvals), and (C) Landlord153s estimate of the change, if any, which shall occur in the cost of the Tenant Improvements affected by such Tenant Change Request if such Tenant Change Request is implemented (including, but not limited to, any costs of compliance with laws or governmental regulations that become applicable because of the implementation of the Tenant Change Request). Landlord shall so notify Tenant within five (5) business days of Landlord153s receipt of the Tenant Change Request, provided that such period shall

-16-


be extended by up to two (2) additional business days if because of the nature of the proposed changes, alterations or additions, Landlord cannot reasonably respond within a five (5) business day period. If Landlord approves the Tenant Change Request and Tenant notifies Landlord in writing, within five (5) business days after receipt of such notice from Landlord, of Tenant153s approval of the Tenant Change Request (including the estimated delays and cost increases, if any, described in Landlord153s notice), then Landlord shall cause such Tenant Change Request to be implemented, and any actual delays resulting therefrom shall be deemed to be a Tenant Delay, and any actual change in costs incurred shall be a part of the Total Project Cost. If Tenant fails to notify Landlord in writing of Tenant153s approval of such Tenant Change Request within said five (5) business day period, then such Tenant Change Request shall be deemed to be withdrawn and shall be of no further effect.

(e) Project Management. Unless and until revoked by Landlord by written notice delivered to Tenant, Landlord hereby (i) delegates to Project Manager the authority to exercise all approval rights, supervisory rights and other rights or powers of Landlord under this Workletter with respect to the design and construction of the Tenant Improvements, and (ii) requests that Tenant work with Project Manager with respect to any logistical or other coordination matters arising in the course of construction of the Tenant Improvements, including monitoring Tenant153s compliance with its obligations under this Workletter and under the Lease with respect to the design and construction of the Tenant Improvements. Tenant acknowledges the foregoing delegation and request, and agrees to cooperate reasonably with Project Manager as Landlord153s representative pursuant to such delegation and request.

3. Completion.

(a) When Landlord receives written certification from Architect that construction of the Warm Shell Work and Tenant Improvements in the Building has been completed in accordance with the Landlord153s Approved Plans (except for Punch List Work), Project Manager or other representatives of Landlord shall conduct one or more "walkthroughs" of the Building with Tenant and Tenant153s representatives, to mutually identify any items of Punch List Work that may require correction and to prepare a joint punch list reflecting any such items. Landlord shall prepare and deliver to Tenant a certificate signed by both Landlord and Architect (the "Substantial Completion Certificate"), in accordance with the AIA standard form, (i) certifying that the construction of the Warm Shell Work and the Tenant Improvements in the Building has been substantially completed in a good and workmanlike manner in accordance with the Landlord153s Approved Plans in all material respects, subject only to completion of Punch List Work, and that all governmental approvals necessary for Tenant153s legal occupancy of the Building have been issued, and specifying the date upon which both of those conditions have been satisfied, (ii) certifying that the Warm Shell Work and Tenant Improvements comply with all laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto at the time of such delivery, and setting forth the Punch List Work. Upon receipt by Tenant of the Substantial Completion Certificate and tender of possession of the Premises by Landlord to Tenant, Tenant Improvements in the Building will be deemed delivered to Tenant and the New Building Commencement Date for all purposes of the Lease (subject to Landlord153s continuing obligations with respect to any Punch List Work, and to any other express obligations of Landlord under the Lease or this Workletter with respect to such Tenant Improvements) shall be deemed to have occurred.

(b) Promptly following delivery of the Substantial Completion Certificate for the Warm Shell Work and Tenant Improvements in the Building, Landlord shall diligently complete the Punch List Work reflected in such joint punch list within thirty (30) days. Tenant acknowledges that depending on the nature and scope of the punch list items, certain work may extend beyond such 30-day period. Promptly after Landlord provides Tenant with the Substantial Completion Certificate and completes all applicable Punch List Work for the Building, Landlord shall cause the recordation of a

-17-


Notice of Completion (as defined in Section 3093 of the California Civil Code) with respect to the Warm Shell Work and Tenant Improvements in the Building. Landlord shall conduct at least one (1) additional "walkthrough" with Tenant and Tenant153s representatives after the date which is ten (10) months following the delivery of the Substantial Completion Certificate to identify any defects in construction or required repairs that might be covered by a warranty or guaranty obtained in connection with the construction of the Warm Shell Work and Tenant Improvements.

(c) All construction, product and equipment warranties and guaranties obtained by Landlord with respect to the Warm Shell Work and Tenant Improvements shall, to the extent reasonably obtainable, include a provision that such warranties and guaranties shall also run to the benefit of Tenant, and Landlord shall cooperate with Tenant in a commercially reasonable manner to assist in enforcing all such warranties and guaranties for the benefit of Tenant, whether or not such warranties and guaranties expressly run to the benefit of Tenant.

(d) Notwithstanding any other provisions of this Workletter or of the Lease, if Landlord is delayed in substantially completing any of Tenant Improvements as a result of any Tenant Delay, then notwithstanding any other provisions of the Lease to the contrary, the Tenant Improvements shall be deemed to have been substantially complete on the date the Tenant Improvements would have been substantially complete absent such Tenant Delay. The number of days of any Landlord Delays or Unavoidable Delays shall be credited against the number of days of any Tenant Delays, however.

4. Payment of Costs. Subject to Landlord153s provision of the Tenant Improvement Allowance, Tenant shall pay all of the Total Project Cost, as defined in Section 4(b), below.

(a) Tenant Improvement Allowance. Tenant shall be entitled to a one-time improvement allowance (the "Tenant Improvement Allowance") in the amount of $50.00 per rentable square foot of the Premises (i.e., $3,500,000.00) for the costs relating to the initial design and construction of the Tenant Improvements.

(b) Cost Proposal; Contract; Allowance Election. After Landlord and Tenant have approved the Landlord153s Final Working Drawings, Landlord shall cause General Contractor to solicit subcontractor bids based on Landlord153s Final Working Drawings. Landlord, Tenant and the General Contractor shall mutually review the bids and discuss the same with the bidding subcontractors, and shall mutually agree upon the subcontractors. After the subcontractors have been selected based on such bidding process, Landlord shall cause the General Contractor to enter into a construction contract (the "Contract"). In connection with the foregoing, if Tenant shall fail to respond to any request by Landlord with respect to approvals of the cost proposal or final Contract price within seven (7) business days after Landlord153s request (provided that, if the dates upon which such approvals are requested deviate significantly from the dates for such actions as set forth in the Schedule for any reason other than a Landlord Delay or an Unavoidable Delay,, such time period shall be extended to be ten (10) business days), any delay as a result of such failure shall be deemed to be a Tenant Delay. As used herein the "Total Project Cost" shall be equal to the sum of (i) the cost of the preparation of all of the plans and specifications for the Tenant Improvements (including the Preliminary Plan and the Landlord153s Final Working Drawings, and Landlord153s Approved Plans), and (ii) all other amounts to be expended in connection with the construction of the Tenant Improvements, as included in project budget documentation provided by Landlord to Tenant from time to time for which Landlord will be holding the contracts or making payments (e.g., design costs and permit fees). Total Project Cost shall not include items or work for which Tenant contracts directly.

-18-


(c) Over Allowance Amount. The amount by which the Total Project Cost exceeds the amount of the Tenant Improvement Allowance remaining as of the commencement of construction of the Tenant Improvements is referred to herein as the "Over Allowance Amount". During the course of construction of the Tenant Improvements, Tenant shall pay a fraction of each amount to be disbursed by Landlord or otherwise paid pursuant to the terms of this Tenant Work Letter (the "Over Allowance Payments"), the numerator of which fraction shall equal the projected Over Allowance Amount, and the denominator of which fraction shall equal the projected Total Project Cost, and such payment by Tenant shall be a condition to Landlord153s obligation to pay any amounts of the Tenant Improvement Allowance. To the extent the projected Total Project Cost changes during the course of design and construction of the Tenant Improvements, including as the result of any Tenant Change Requests, the Over Allowance Payments shall be appropriately adjusted. Any delays in the construction of the Tenant Improvements resulting from Tenant153s failure to make any Over Allowance Payments shall be a Tenant Delay.

(d) Disbursement. Except as otherwise set forth in this Work Letter, the Tenant Improvement Allowance shall be disbursed by Landlord (each of which disbursements shall be made pursuant to Landlord153s disbursement process, including, without limitation, Landlord153s receipt of invoices for all costs and fees described herein) for costs related to the design, permitting, supervision and construction of the Tenant Improvements, including any changes to the existing Building condition required in connection therewith. Landlord shall provide Tenant with a copy of each applicable draw request. Tenant shall approve such draw request (which approval shall not be unreasonably withheld, and shall not be withheld if the draw request is within the approved budget, or is otherwise within the previously approved Total Project Cost), and provide Landlord with any required Over Allowance Payments within thirty (30) days after Tenant153s receipt of such draw request. Tenant153s failure to respond to a request for approval within such 30-day period shall be deemed to constitute Tenant153s approval of such request (but such deemed approval shall not be deemed to be Tenant153s agreement that the work to which such payment relates has been performed satisfactorily in accordance with the Landlord153s Approved Plans, or to waive Tenant153s ability to require any deficiencies in such work to be corrected at a later date). In addition, Landlord shall submit to Tenant monthly during the performance of the Tenant Improvements a report setting forth in detail: (i) a computation of the Total Project Costs incurred during the prior month (including all requested and approved Change Orders); and (ii) the cumulative Total Project Costs incurred through the end of such month. Such report shall be submitted by the fifteenth (15th) day of each month and shall be accompanied by invoice back-ups and conditional or unconditional lien releases as received by Landlord. All Total Project Costs and Tenant153s share (if any) thereof shall be subject to audit, verification, and correction, if necessary, by Tenant and/or its authorized representatives (who shall have access to the relevant portions of the Landlord153s books and records for such purpose) without either party being prejudiced by any payment thereunder.

(e) Project Manager Fees. Landlord shall receive a reimbursement of fees payable to its Project Manager in the amount of $2.06 per rentable square foot of the Premises (the "PMA Fee"), which shall be deducted from the Tenant Improvement Allowance. If the Total Project Cost exceeds $100.00 per rentable square foot of the Premises (i.e., $7,000,000), then the PMA Fee shall be increased by an amount equal to 2.9% of such overage.

(f) Unused Portion of Tenant Improvement Allowance. Any amounts of the Tenant Improvement Allowance not disbursed or allocated by the date that is one (1) year after the substantial completion of the Tenant Improvements shall revert to Landlord and Tenant shall have no further rights with respect thereto; provided, however, that the one (1)- year deadline shall be extended if the Tenant Improvement Allowance has not been disbursed for allocated as a result of the failure of the Contractor or any subcontractor, materialman or other party providing equipment, materials or services in connection with the construction of the Tenant Improvements to timely submit invoices therefor.

-19-


(g) Notwithstanding the foregoing or anything to the contrary in this Workletter, the Total Project Costs shall not include, the Tenant Improvement Allowance shall not be used for, and Landlord shall bear all costs with respect to: (i) any work to the Building, or Premises or Center other than the Tenant Improvements (other than work contracted by or on behalf of Tenant directly, and not as a part of the Tenant Improvements); (ii) premiums or the incremental portion thereof for insurance policies required under the Lease to be procured by Landlord (other than Builder153s All Risk or similar insurance reasonably procured with respect to the construction of the Tenant Improvements); (iii) charges and expenses for changes to the Approved Plans that have not been approved by Tenant, have not been required by applicable law; (iv) wages, labor and overhead for over-time and premium time (unless approved in writing by Tenant); (v) additional costs and expenses incurred by Landlord on account of any contractor153s or subcontractor153s default or construction defects; (vi) principal, interest and fees for construction and permanent financing; (vii) except for the PMA Fee or other costs as expressly set forth in this Workletter, fees or charges for construction management, supervision, profit, overhead or general conditions by Landlord or any third party other than the contractors who are performing the Tenant Improvements; (viii) costs for which Landlord receives reimbursement from others, including, without limitation, insurers and warrantors (Landlord shall use commercially reasonable efforts to maximize the amount of all reimbursements to which it is entitled); (ix) restoration costs in excess of insurance proceeds as a consequence of casualties; (x) penalties and late charges attributable to Landlord153s failure to pay the Total Project Costs; (xi) attorneys153, experts153 and other fees and costs in connection with contracts and disputes; and (xii) costs arising from or in connection with the presence of Hazardous Substances on the Premises or Center not introduced by Tenant.

5. No Agency. Nothing contained in this Workletter shall make or constitute Tenant as the agent of Landlord.

6. Miscellaneous. All references in this Workletter to a number of days shall be construed to refer to calendar days, unless otherwise specified herein. If any item requiring approval is disapproved by Landlord or Tenant (as applicable) in a timely manner, the procedure for preparation of that item and approval shall be repeated.

7. Delays in Warm Shell Work, Tenant Improvements. Notwithstanding anything to the contrary contained in this Workletter or the 6th Amendment, if (i) substantial completion of the Warm Shell Work is not completed by the date set forth in the Schedule due to any Landlord Delay or Unavoidable Delay, and as a result of such Landlord Delay or Unavoidable Delay substantial completion of the Tenant Improvements is delayed beyond March 1, 2013, or (ii) if substantial completion of the Tenant Improvements is delayed beyond March 1, 2013, due to any Landlord Delay or Unavoidable Delay, then, subject to any Tenant Delay, the New Building Commencement Date shall be delayed day for day by the same number of days of Landlord Delay and Unavoidable Delays.
