WORK LETTER

[TENANT BUILD W/ALLOWANCE]

Tenant intends to complete the Tenant Improvements on or before December 1, 2019.

2. WORK SCHEDULE. Prior to commencing construction, Tenant will deliver to Landlord, for Landlord’s review and approval, a schedule (“Work Schedule”), which will set forth the timetable for the planning and completion of the installation of the Tenant Improvements.

Either party may change its representative under this Work Letter at any time by written notice to the other party in compliance with the notice provisions of the Original Lease.

4. TENANT IMPROVEMENT PLANS

(a) Preparation of Space Plans. In accordance with the Work Schedule, Landlord agrees to meet with Tenant’s architect and/or space planner for the purpose of promptly reviewing preliminary space plans for the layout of the Premises prepared by Tenant (“Space Plans”). Landlord shall provide Tenant and its design professionals with as-built plans and specifications for the base Building and Building systems promptly following the Effective Date (collectively, the “Base Building Plans”). The Space Plans are to be sufficient to convey the architectural design of the Premises and layout of the Tenant Improvements therein and are to be submitted to Landlord in accordance with the Work Schedule for Landlord’s approval, including as to floor space configuration and implementation of Building Standard improvements and finishes or better as utilized in Suite 150 of the Premises as to all lobby and common corridors, ceiling tiles, lights (based on the portion of Suite 150 with drop ceilings), doors, hardware, glass (sidelight or full glass) and kitchen finishes as the “Minimum Specifications and Finishes”. Attached hereto as Exhibit B-1 is a detailed specification sheet for the Minimum Specifications and Finishes. Landlord agrees not to withhold its approval as to elements of Tenant’s Space Plans to the extent conforming to or exceeding Landlord’s Minimum Specifications and Finishes. If Landlord reasonably disapproves any aspect of the Space Plans other than as to specifications and finishes which meet Landlord’s Minimum Specifications and Finishes, Landlord will advise Tenant in writing of such disapproval and the reasons therefor in accordance with the Work Schedule. Tenant will then submit to Landlord for Landlord’s approval, in accordance with the Work Schedule, a redesign of the Space Plans incorporating the revisions reasonably required by Landlord. Landlord shall advise Tenant within five (5) business days after Landlord's receipt of the Space Plans if the same are unsatisfactory or incomplete in any respect. Landlord’s notice of disapproval of the Space Plans, if any, shall describe the basis for Landlord’s disapproval (based upon a commercially reasonable standard) in reasonable detail, as well as the changes which Landlord requires in order to approve the Space Plans and the Space Plans shall not be disapproved where and to the extent conforming to or exceeding Landlord’s Minimum Specifications and Finishes. If Tenant is so advised, Tenant shall promptly cause the Space Plans to be revised to Landlord’s reasonable satisfaction. The foregoing Space Plans procedure, and the submissions/approvals related thereto, shall be followed until the Space Plans are approved by Landlord, however, after the initial review, Landlord shall respond within three (3) business days to any revisions, and any failure of Landlord to respond within the foregoing time periods shall constitute Landlord’s approval of the Space Plans in form most recently provided by Tenant to Landlord (collectively, the “Landlord Approval Process”).

(b) Preparation of Final Plans. Based on the approved Space Plans, and in accordance with the Work Schedule, Tenant’s architect will prepare complete architectural plans, drawings and specifications and complete engineered mechanical, structural and electrical working drawings for all of the Tenant Improvements for the Premises (collectively, the “Final Plans”). The Final

Plans will show (a) the subdivision (including partitions and walls), layout, lighting, finish and decoration work (including carpeting and other floor coverings) for the Third Floor Expansion Space; (b) all internal and external communications and utility facilities which will require conduiting or other improvements from the base Building shell work and/or within common areas; and (c) all other specifications for the Tenant Improvements. The Final Plans will be submitted to Landlord for signature to confirm that they are consistent with the Space Plans. If Landlord reasonably disapproves any aspect of the Final Plans based on any inconsistency with the Space Plans, Landlord agrees to advise Tenant in writing of such disapproval and the reasons therefor within the time frame set forth in the Work Schedule and, in all events, consistent with the Landlord Approval Process (as the same shall be applied to the approval of the Final Plans). In accordance with the Work Schedule and the Landlord Approval Process, as applicable, Tenant will then cause Tenant’s architect to redesign the Final Plans incorporating the revisions reasonably requested by Landlord so as to address any inconsistency with the Space Plans or other design issues.

(c) Requirements of Tenant’s Final Plans. Tenant’s Final Plans will include locations and complete dimensions, and the Tenant Improvements, as shown on the Final Plans, will: (i) be compatible with the Building shell and with the design, construction and equipment of the Building; (ii) if not comprised of the Building standards set forth in the written description thereof (the “Standards”), then compatible with and of at least equal quality as the Standards and approved by Landlord; (iii) comply with all applicable laws, ordinances, rules and regulations of all governmental authorities having jurisdiction, and all applicable insurance regulations; (iv) not require Building service beyond the level normally provided to other tenants in the Building and will not overload the Building floors; and (v) be of a nature and quality consistent with the overall objectives of Landlord for the Building, as determined by Landlord in its reasonable but subjective discretion.

(d) Submittal of Final Plans. Once approved by Landlord and Tenant, Tenant’s architect will submit the Final Plans to the appropriate governmental agencies for plan checking and the issuance of a building permit. Tenant’s architect, with Landlord’s cooperation, will make any changes to the Final Plans which are requested by the applicable governmental authorities to obtain the building permit. After approval of the Final Plans no further changes may be made without the prior written approval of both Landlord and Tenant, and then only after agreement by Tenant to pay any excess costs resulting from the design and/or construction of such changes, if any. Notwithstanding the foregoing, the cost to make any changes to the Final Plans resulting from defects in the construction of the Building, or for pre-existing violations of applicable law applicable to the Building (collectively, “Existing Building Defects or Violations”) shall be borne solely by Landlord and shall not reduce the Allowance available to Tenant.

(e) Changes to Shell of Building. If the Final Plans or any amendment thereof or supplement thereto shall require changes in the Building shell, the increased cost of the Building shell work caused by such changes will be paid for by Tenant or charged against the “Allowance” described in Section 5 below, excluding any changes due to Existing Building Defects or Violations which shall be borne solely by Landlord and shall not reduce the Allowance available to Tenant.

(f) Work Cost Estimate and Statement. Prior to the commencement of construction of any of the Tenant Improvements shown on the Final Plans, Tenant will submit to Landlord a written estimate of the cost to complete the Tenant Improvement Work, which written estimate will be based on the Final Plans taking into account any modifications which may be required to reflect changes in the Final Plans required by the City or County in which the Premises are located (the “Work Cost Estimate”). Landlord will either approve the Work Cost Estimate or disapprove specific items that are inconsistent with the Final Plans and submit to Tenant revisions to the Final Plans to reflect deletions of and/or substitutions for such disapproved items. Submission and approval of the Work Cost Estimate will proceed in accordance with the Work Schedule and the Landlord Approval Process (as the same shall be applied to the approval of the Work Cost Estimate, provided that Landlord’s review shall be limited to identifying specific items in the Work Cost Estimate that are inconsistent with the Final Plans). Upon Landlord’s approval of the Work Cost Estimate (such approved Work Cost Estimate to be hereinafter known as the “Work Cost Statement”), Tenant will have the right to purchase materials and to commence the construction of the items included in the Work Cost Statement pursuant to Section 6 hereof. If the total costs reflected in the Work Cost Statement exceed the Allowance described in Section 5 below, Tenant agrees to pay such excess.

(g) Defects in Design Documents. Tenant and Tenant’s architect and space planner and other design professionals ( “Tenant’s Design Team”) shall be entitled to rely on the accuracy and correctness of the Base Building Plans to the extent and in the degree customary in the design and construction industry for projects in the same locality as the Project and similar in size and scope to the design of the Tenant Improvements. In the event the Space Plan or the Final Plan (collectively, the “Tenant Improvement Construction Documents”) become materially inaccurate as a result of Tenant’s Design Team’s reliance on the Base Building Plans, and such Base Building Plans are determined to be materially inconsistent with the Building as constructed, then, Landlord shall be responsible for the actual cost to Tenant to effect the correction to the Tenant Improvement Construction Documents to alleviate such deficiency and Landlord shall pay the actual cost to correct such Tenant Improvement Construction Documents (as such cost shall be verified to Landlord’s reasonable satisfaction), or to perform at Landlord’s expense in accordance with the corrected Tenant Improvement Construction Documents, the re-construction of the materially adversely affected portions of the Tenant Improvements.

If increases in the cost of the Tenant Improvements as set forth in the Work Cost Statement are due to requirements of any governmental agency (excluding any changes due to Existing Building Defects or Violations which shall be borne solely by Landlord and shall not reduce the Allowance available to Tenant), Tenant shall be solely responsible for such additional costs including the Construction Administration Fee (as and when performance of such changes actually occurs), which fee shall be paid to Landlord within five (5) business days after invoice therefor; provided, however, that Landlord will first apply toward any such increase any remaining balance of the Allowance.

(e) Unused Allowance Amounts. Any unused portion of the Allowance upon completion of the Tenant Improvements will not be refunded to Tenant or be available to Tenant as a credit against any obligations of Tenant under the Lease.

(f) Disbursement of the Allowance. Provided Tenant is not in default following the giving of notice and passage of any applicable cure period under the Amended Lease or this Work Letter which is then continuing, Landlord shall disburse the Allowance to Tenant not less frequently than monthly to reimburse Tenant for the actual construction costs which Tenant incurs in connection with the construction of the Tenant Improvements upon completion of the Tenant Improvements included in such disbursement request and satisfaction of the following conditions:

(i) Tenant has delivered to Landlord a draw request (“Draw Request”) in the form attached as Exhibit B-1 with respect to the Improvements specifying that the requisite portion of Tenant’s Work has been completed, together with invoices, receipts and bills evidencing the costs and expenses set forth in such Draw Request and evidence of payment by Tenant for all costs which are payable in connection with such Tenant’s Work covered by the Draw Request. The Draw Request shall constitute a representation by Tenant that, to Tenant’s actual knowledge, the Tenant’s Work identified therein has been completed in a good and workmanlike manner and in accordance with the Final Plans and the Work Schedule;

(ii) The architect for the Tenant Improvements has certified to Landlord that the Tenant Improvements have been completed to the level indicated in the Draw Request in accordance with the Final Plans;

(iii) Tenant has delivered to Landlord properly executed mechanics lien releases from all of Tenant’s contractors, agents and suppliers in compliance with California Civil Code Sections 8120 through 8138, which lien releases shall be conditional with respect to the then-requested payment amounts and unconditional with respect to payment amounts previously disbursed by Landlord;

(iv) Landlord or Landlord’s architect or construction representative has inspected the Tenant Improvements and determined that the portion of Tenant’s Work covered by the Draw Request has been completed in a good and workmanlike manner;

(v) With respect to the final disbursement of the Allowance, which shall include all retention amounts owed to Tenant’s general contractor (“Final Disbursement”), not less than thirty-five (35) days shall have elapsed following the filing of a valid notice of completion by Tenant for the Tenant Improvements;

(vi) With respect to the Final Disbursement, Tenant has delivered to Landlord: (i) properly executed mechanics lien releases from all of Tenant’s contractors, agents and suppliers in compliance with both California Civil Code Sections 8120 through 8138, which lien releases shall be conditional with respect to the then-requested payment amounts and unconditional with respect to payment amounts previously disbursed by Landlord; (ii) an application and certificate for payment (AIA form G702-1992 or equivalent) signed by Tenant’s architect/space planner; (iii) original stamped building permit plans; (iv) copy of the building permit; (v) original stamped building permit inspection card with all final sign-offs; (vi) a reproducible copy (in a form approved by Landlord) of the “as-built” drawings of the Tenant Improvements; (vii) air balance reports; (viii) excess energy use calculations; (ix) one year warranty letters from Tenant’s general contractors; (x) manufacturer’s warranties and operating instructions; (xi) final punchlist completed and signed off by Tenant’s architect/space planner; and (xii) an acceptance of the Third Floor Expansion Space signed by Tenant; and

6. CONSTRUCTION OF TENANT IMPROVEMENTS. Following Landlord’s approval of the Final Plans and the Work Cost Statement described in Section 4(f) above, Tenant’s contractor (selected or pre-approved as provided in Section 8(n)) will commence and diligently proceed with the construction of the Tenant Improvements. Tenant shall use commercially reasonable efforts to cause its contractor to complete the Tenant Improvements in a good and workmanlike manner in accordance with the Final Plans and the Work Schedule. Tenant agrees to use commercially reasonable efforts to cause construction of the Tenant Improvements to commence promptly following the issuance of a building permit for the Tenant Improvements. Landlord shall

have the right to enter upon the Third Floor Expansion Space to inspect Tenant’s construction activities following reasonable advance notice Tenant.

7. DELIVERY OF POSSESSION; TERM AND RENT COMMENCEMENT DATE

(a) Delivery of Possession. Landlord agrees to deliver possession of the Third Floor Expansion Space (currently vacant) to Tenant promptly following execution of this Amendment by the parties in the condition required under the Amended Lease.

(b) Third Floor Expansion Space Commencement Date. The Third Floor Expansion Space Commencement Date and Tenant’s obligation to pay rent with respect to the Third Floor Expansion Space will commence upon the earlier of (i) substantial completion of the Tenant Improvements (as defined below in Section 7(c)) below or (ii) January 1, 2020 (the “TFESCD”).

(c) Substantial Completion; Punch-List. For purposes of Section 8(b) above, the Tenant Improvements will be deemed to be “substantially completed” when Tenant’s contractor certifies in writing to Landlord and Tenant that Tenant has substantially performed all of the Tenant Improvement Work required to be performed by Tenant under this Work Letter, other than decoration and minor “punch-list” type items and adjustments which do not materially interfere with Tenant’s use of the Third Floor Expansion Space; and Tenant has obtained a temporary certificate of occupancy or other required equivalent approval from the local governmental authority permitting occupancy of the Third Floor Expansion Space. Within ten (10) days after receipt of such certificates, Tenant and Landlord will conduct a walk-through inspection of the Third Floor Expansion Space and Landlord shall provide to Tenant a written punch-list specifying those decoration and other punch-list items which require completion in accordance with the Final Plans, which items Tenant will thereafter diligently complete.

8. MISCELLANEOUS CONSTRUCTION COVENANTS

(a) No Liens. Tenant shall not allow the Tenant Improvements or the Building or any portion thereof to be subjected to any mechanic’s, materialmen’s or other liens or encumbrances arising out of the construction of the Tenant Improvements.

(b) Diligent Construction. Tenant will promptly, diligently and continuously pursue construction of the Tenant Improvements to completion in compliance in all material respects with the Final Plans, the Work Schedule and this Work Letter. Landlord and Tenant shall cooperate with one another during the performance of Tenant’s Work to effectuate such work in a timely and compatible manner.

(c) Compliance with Laws. Tenant will construct the Tenant Improvements in a safe and lawful manner. Tenant shall, at its sole cost and expense, comply with all applicable laws and all regulations and requirements of, and all licenses and permits issued by, all municipal or other governmental bodies with jurisdiction which pertain to the installation of the Tenant Improvements. Copies of all filed documents and all permits and licenses shall be provided to Landlord. Any portion of the Tenant Improvements which is not acceptable to any applicable governmental body, agency or department, or is not in compliance with the Final Plans, shall be promptly repaired or replaced by Tenant at Tenant’s expense excluding any changes due to Existing Building Defects or Violations which shall be borne solely by Landlord and shall not reduce the Allowance available to Tenant. Notwithstanding any failure by Landlord to object to any such Tenant Improvements, Landlord shall have no responsibility therefor.

(d) Indemnification. Subject to the terms of the Original Lease regarding insurance and waiver of subrogation by the parties, Tenant hereby indemnifies and agrees to defend and hold Landlord, the Third Floor Expansion Space and the Building harmless from and against any and all suits, claims, actions, losses, costs or expenses of any nature whatsoever, together with reasonable attorneys’ fees for counsel of Landlord’s choice, arising out of or in connection with the Tenant Improvements or the performance of Tenant’s Work; provided however all such claims shall be limited to claims for worker’s compensation, personal injury or property damage, and any materialmen’s and mechanic’s liens and shall exclude any such claims arising out of the negligence or misconduct of Landlord or its agents, including Landlord’s Representative.

(e) Insurance. Construction of the Tenant Improvements shall not proceed without Tenant first requiring that its general contractor maintain workers’ compensation and commercial general liability insurance and property damage insurance as well as “All Risks” builders’ risk insurance, with minimum coverage of $2,000,000 or such other amount as may be approved by Landlord in writing and issued by an insurance company reasonably satisfactory to Landlord. Not less than ten (10) days before commencing the construction of the Tenant Improvements, certificates of such insurance shall be furnished to Landlord. All such policies shall provide that thirty (30) days prior notice must be given to Landlord before modification, termination or cancellation. All insurance policies maintained by Tenant’s contractor pursuant to this Work Letter shall name Tenant, Landlord and any lender with an interest in the Third Floor Expansion Space as additional insureds.

(f) Construction Defects. Landlord shall have no responsibility for the Tenant Improvements and Tenant will remedy, at Tenant’s own expense, and be responsible for any and all defects in the Tenant Improvements (excluding any Existing Building Defects or Violations, the cost of which shall be borne solely by Landlord) that may appear during or after the completion thereof whether the same shall affect the Tenant Improvements in particular or any parts of the Third Floor Expansion Space in general. Tenant shall be responsible for correcting any defect in any portion of the Tenant Improvements constructed by Tenant or Tenant’s contractor or subcontractors (other than arising due to any Existing Building Defects or Violations which shall remain Landlord’s responsibility at its sole cost), or by reason of inadequate cleanup due to, and following completion of, the Tenant Improvements.

(g) Additional Services. If the construction of the Tenant Improvements shall require that additional services or facilities (including, but not limited to, hoisting, cleanup or other cleaning services, trash removal, field supervision, or ordering of materials) be provided by Landlord, then Tenant shall pay Landlord for such items at Landlord’s actual cost without markup. Electrical power and heating, ventilation and air conditioning shall be available to Tenant during normal business hours for construction purposes at no charge to Tenant.

(h) Coordination of Labor. All of Tenant’s contractors, subcontractors, employees, servants and agents must work in harmony with and shall not interfere with any labor employed by Landlord, or Landlord’s contractors or by any other tenant or its contractors with respect to the any portion of the Property. Nothing in this Work Letter shall, however, require Tenant to use union labor.

(i) Work in Adjacent Areas. Any work to be performed in areas adjacent to the Third Floor Expansion Space shall be performed only after obtaining Landlord’s express written permission, which shall not be unreasonably withheld, conditioned or delayed, and shall be done only if an agent or employee of Landlord is present.

(j) HVAC Systems. Tenant agrees to be entirely responsible for the maintenance or the balancing of any heating, ventilating or air conditioning system installed by Tenant and/or maintenance of the electrical or plumbing work installed by Tenant and/or for maintenance of lighting fixtures, partitions, doors, hardware or any other installations made by Tenant.

(k) Coordination with Lease. Nothing herein contained shall be construed as (i) constituting Tenant as Landlord’s agent for any purpose whatsoever, or (ii) a waiver by Landlord or Tenant of any of the terms or provisions of the Amended Lease. Any default by Tenant following the giving of notice and the passage of any applicable cure period with respect to any portion of this Work Letter shall be deemed a breach of the Amended Lease for which Landlord shall have all the rights and remedies as in the case of a breach of said Lease.

(l) Approval of Plans. Landlord will not check Tenant drawings for building code compliance. Approval of the Final Plans by Landlord is not a representation that the drawings are in compliance with the requirements of governing authorities, and it shall be Tenant’s responsibility to meet and comply with all federal, state, and local code requirements. Approval of the Final Plans does not constitute assumption of responsibility by Landlord or its architect for their accuracy, sufficiency or efficiency, and Tenant shall be solely responsible for such matters. In all matters requiring the approval of Landlord under this Work Letter, such approval shall not be unreasonably withheld, conditioned, or delayed.

(m) Tenant’s Deliveries. Tenant shall deliver to Landlord, at least five (5) business days prior to the commencement of construction of Tenant’s Work, the following information:

(i) The names, addresses, telephone numbers, and primary contacts for the general, mechanical and electrical contractors Tenant intends to engage in the performance of Tenant’s Work; and

(ii) The date on which Tenant’s Work will commence, together with the estimated dates of completion of Tenant’s construction and fixturing work (which information may be included in the Work Schedule for purposes of compliance herewith).

(n) Qualification of Contractors. Once the Final Plans have been proposed and approved, Tenant shall select and retain a general contractor, major subcontractors and vendors (such as HVAC engineers) from a list of preferred contractors, subcontractors and vendors provided by Landlord in connection with all aspects of the design and construction of the Tenant Improvement Work in accordance with the Final Plans. All contractors, subcontractors and vendors engaged by Tenant shall be bondable and licensed, possessing good labor relations, capable of performing quality workmanship and working in harmony with Landlord’ s general contractor and other contractors on the job, if any, all as determined by Landlord. All Tenant Improvement Work shall be coordinated with any ongoing general construction work on the Site or in the Building, if any. Landlord hereby approves JB Pacific as Tenant’s general contractor, and Studio Xxxxxx Architecture as Tenant’s architect.

(o) Warranties. Tenant shall cause its general contractor to provide warranties for not less than one (1) year (or such shorter time as may be customary and available without additional expense to Tenant) against defects in workmanship, materials and equipment, which warranties shall run to the benefit of Landlord or shall be assignable to Landlord to the extent that Landlord is obligated to maintain any of the improvements covered by such warranties.

(p) Landlord’s Performance of Work. Within twenty (20) days after receipt of Landlord’s notice of Tenant’s failure to perform its obligations under this Work Letter, if Tenant shall fail to commence to cure such failure, Landlord shall have the right, but not the obligation, to perform, on behalf of and for the account of Tenant, subject to reimbursement of the cost thereof by Tenant, any and all of Tenant’s Work which Landlord determines, in its reasonable discretion, should be performed immediately and on an emergency basis for the best interest of the Third Floor Expansion Space including, without limitation, work which pertains to structural components, mechanical, sprinkler and general utility systems, roofing and removal of unduly accumulated construction material and debris; provided, however, Landlord shall give Tenant at least twenty (20) days prior notice to the performance of any of Tenant’s Work.

(q) As-Built Drawings. Tenant shall cause “As-Built Drawings” (excluding furniture, fixtures and equipment) to be delivered to Landlord and/or Landlord’s representative no later than sixty (60) days after the completion of Tenant’s Work. In the event these drawings are not received by such date, Landlord may, at its election, cause said drawings to be obtained and Tenant shall pay to Landlord, as additional rent, the cost of producing these drawings.

9. FREIGHT/CONSTRUCTION ELEVATOR. Landlord will, consistent with its obligation to other tenants in the Building, if appropriate and necessary, make the freight/construction elevator reasonably available to Tenant in connection with the construction of the Tenant Improvements. Tenant agrees to pay for any after-hours staffing of the freight/construction elevator, if needed.

RIDER NO. 1 TO AMENDMENT

RIGHT OF FIRST OFFER

This Rider No. 1 is made and entered into by and between TREA PACIFIC PLAZA, LLC, a Delaware limited liability company (“Landlord”), and TANDEM DIABETES CARE, INC., a Delaware corporation (“Tenant”), as of the day and year of the Amendment between Landlord and Tenant to which this Rider is attached. Landlord and Tenant hereby agree that, notwithstanding anything contained in the Original Lease to the contrary, the provisions set forth below shall be deemed to be part of the Amended Lease and shall supersede any inconsistent provisions of the Original Lease. All references in the Original Lease and in this Rider to the “Lease” shall be construed to mean the Amended Lease (and all exhibits and Riders attached thereto), as amended and supplemented by this Rider. All capitalized terms not defined in this Rider shall have the same meaning as set forth in the Amended Lease.

1. Grant of Option; Conditions. Subject to the terms and conditions of this Rider No. 1, Tenant shall have a one-time right of first offer to lease (the “Right of First Offer”) Suite 100 on the first (1^st) floor in the Building (“ROFO Space”). Tenant’s Right of First Offer shall be exercised as follows: at any time after Landlord has determined that the existing tenant in the ROFO Space as of the Effective Date of the Amendment to which this Rider is attached (Cisco) will not extend or renew the term of its lease for such ROFO Space (but prior to leasing such ROFO Space to a party other than the existing tenant), Landlord shall deliver written notice to Tenant (the “ROFO Notice”) of the terms under which Landlord is prepared to lease the ROFO Space to Tenant including rental rate and length of term, which terms shall reflect the then fair market rental rate (hereinafter defined) for such ROFO Space. Tenant may lease such ROFO Space in its entirety only, under such terms, by delivering written notice of exercise to Landlord (the “Notice of Exercise”) within thirty (30) days after the date of the ROFO Notice, except that Tenant shall have no such Right of First Offer and Landlord need not provide Tenant with a ROFO Notice, if:

a. Tenant is in default under the Amended Lease beyond any applicable cure periods at the time that Landlord would otherwise deliver the ROFO Notice; or

b. the existing tenant in the ROFO Space has notified Landlord that they intend to renew or extend its lease for such ROFO Space.

2. Terms for ROFO Space.

a. The term for the ROFO Space shall commence upon the commencement date stated in the ROFO Notice and thereupon such ROFO Space shall be considered a part of the Premises, provided that all of the terms stated in the ROFO Notice shall govern Tenant’s leasing of the ROFO Space and only to the extent that they do not conflict with the ROFO Notice, the terms and conditions of this Lease shall apply to the ROFO Space. The term for the ROFO Space shall expire per the terms of the ROFO Notice, notwithstanding that the expiration date stated in the ROFO Notice may not be coterminous with the then expiration date for the Premises Term.

b. Tenant shall pay Base Rent and Additional Rent for the ROFO Space in accordance with the terms and conditions of the ROFO Notice or as otherwise agreed by Landlord and Tenant.

c. The ROFO Space (including improvements and personalty, if any) shall be accepted by Tenant in its condition and as-built configuration existing on the earlier of the date Tenant takes possession of the ROFO Space or as of the date the term for such ROFO Space commences, unless the ROFO Notice specifies any work to be performed by Landlord in the ROFO Space, in which case Landlord shall perform such work in the ROFO Space. If Landlord is delayed delivering possession of the ROFO Space due to the holdover or unlawful possession of such space by any party, Landlord shall use reasonable efforts to obtain possession of the space, and the commencement of the term for the ROFO Space shall be postponed until the date Landlord delivers possession of the ROFO Space to Tenant free from occupancy by any party subject to such outside date therefor as the parties shall agree upon.

3. Termination of Right of First Offer. The rights of Tenant hereunder with respect to the ROFO Space shall terminate on the earlier to occur of: (i) Tenant’s failure to exercise its Right of First Offer within the thirty (30) day period provided in Section 1 above; and (ii) the date Landlord would have provided Tenant a ROFO Notice if one or more of the conditions set forth in Section 1(a) and 1(b) above then exists; provided that (i) Landlord shall have contemporaneously provided written notice of the existence of such condition to Tenant, and (ii) if the condition described in Section 1(b) above is the basis for Landlord’s failure to send the ROFO Notice, and Landlord and the tenant described in Section 1(b) above do not enter into a binding extension, renewal, or lease of the ROFO Space, then Tenant’s Right of First Offer with respect to the ROFO Space shall again apply.

4. ROFO Amendment. If Tenant exercises its Right of First Offer, Landlord shall prepare an amendment (the “ROFO Amendment”) adding the ROFO Space to the Premises on the terms set forth in the ROFO Notice and reflecting the changes in the Base Rent, Rentable Square Footage of the Premises, Tenant’s Proportionate Share and other appropriate terms. A copy of the ROFO Amendment shall be sent to Tenant promptly after Landlord’s receipt of the Notice of Exercise executed by Tenant, and Tenant shall execute and return the ROFO Amendment to Landlord within fifteen (15) days thereafter provided such ROFO Amendment reflects the terms set forth in this Rider.

5. Subordination. Notwithstanding anything herein to the contrary, Tenant’s Right of First Offer is subject and subordinate to any renewal of Landlord’s lease with the existing tenant of the ROFO Space, Cisco, pursuant to any option or agreement between Landlord and Cisco to stay in the Building.
