8.7^th Floor TI Allowance; Construction of 7^th Floor Tenant Improvements.

(a) 7^th Floor TI Allowance. Following the Amendment Execution Date, Landlord shall make available to Tenant a tenant improvement allowance (the “7^th Floor TI Allowance”) in the amount of Two Million Four Hundred Seventy Two Thousand Nine Hundred Eighty and 15/100 Dollars ($2,472,980.15) (based upon One Hundred Thirty and 15/100 Dollars ($130.15) per square foot of Rentable Area of the 7^th Floor Premises) in order to fund tenant improvements (the “7^th Floor Tenant Improvements”) to the 7^th Floor Premises consistent with the 7^th Floor Permitted Use. Tenant shall cause the 7^th Floor Tenant Improvements to be constructed in the 7^th Floor Premises pursuant to the work letter attached hereto as Exhibit B (the “7^th Floor Work Letter”) at a cost to Landlord not to exceed the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right [defined below]), subject to Landlord’s obligations under Section 2.3(a) of the 7^th Floor Work Letter regarding costs incurred with respect to any Change (as defined in the 7^th Floor Work Letter) requested by Landlord. The 7^th Floor TI Allowance may be applied to the costs of (m) construction, (n) project review by Landlord (which fee, as set forth in Section 17.10 of the Existing Lease, shall equal two percent (2%) of the cost of the 7^th Floor Tenant Improvements, including the 7^th Floor TI Allowance, but shall not exceed Forty Thousand and No/100 Dollars ($40,000.00)), (o) commissioning of mechanical, electrical and plumbing systems by a licensed, qualified commissioning agent hired by Tenant, and review of such party’s commissioning report by a licensed, qualified commissioning agent hired by Landlord, (p) space planning, architect, engineering and other related services performed by third parties unaffiliated with Tenant, (q) building permits and other taxes, fees, charges and levies by Governmental Authorities for permits or for inspections of the 7^th Floor Tenant Improvements, and (r) costs and expenses for labor, material, equipment and fixtures, provided that no more than five percent (5%) of the 7^th Floor TI Allowance may be applied towards the cost of the purchase and installation of cabling and telecom improvements within the 7^th Floor Premises. In no event shall the 7^th Floor TI Allowance be used for (v) the cost of work that is not authorized by the Approved Plans (as defined in the 7^th Floor Work Letter) or otherwise approved in writing by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed), (w) payments to Tenant or any affiliates of Tenant, (x) except as otherwise provided in this Section, the purchase of any furniture, personal property or other non-building system equipment, (y) costs resulting from any default by Tenant of its obligations under the Lease or (z) costs that are recoverable by Tenant from a third party (e.g., insurers, warrantors, or tortfeasors). Notwithstanding anything to the contrary in this Amendment, Landlord shall not charge Tenant any plan or construction review, oversight, supervision, management or other similar fee in relation to the 7^th Floor Tenant Improvements other than the amount set forth in clause (n) above. In addition to the 7^th Floor TI Allowance, Landlord shall contribute up to Two Thousand Eight Hundred Fifty and 15/100 Dollars ($2,850.15) (based upon 15/100 Dollars ($0.15) per square foot of Rentable Area of the 7^th Floor Premises) to pay the cost of developing a test fit plan for the 7^th Floor Premises (the “7^th Floor Test Fit Allowance”), which shall be disbursed by Landlord directly to Tenant’s architect in accordance with the 7^th Floor Work Letter.

(b) 7^th Floor TI Deadline. Tenant shall have until the date that is one (1) year after the 7^th Floor Term Commencement Date (the “7^th Floor TI Deadline”), to expend the unused portion of the 7^th Floor TI Allowance and the 7^th Floor Test Fit Allowance, after which date Landlord’s obligation to fund such costs shall expire.

(c) Application of Tenant Allowances. If the cost of the 7^th Floor Tenant Improvements to be performed by Tenant exceeds the amount of the 7^th Floor TI Allowance, then Tenant shall have the right (the “7^th Floor TI Allowance Reallocation Right”) to reallocate all or a portion of any unused TI Allowance for the Original Premises (the “Original Premises TI Allowance”) under the Lease (any such reallocated amount, the “7^th Floor Reallocated TI Allowance Amount”) to pay such excess cost of constructing the 7^th Floor Tenant Improvements (subject to the limitations set forth in the Lease), on the terms and conditions set forth in the 7^th Floor TI Allowance Reallocation Agreement attached as Exhibit C hereto (the “7^th Floor TI Allowance Reallocation Agreement”). In no event shall any unused 7^th Floor TI Allowance or 7^th Floor Test Fit Allowance entitle Tenant to a credit against Rent payable under the Lease. Upon Tenant’s exercise of the 7^th Floor TI Allowance Reallocation Right, the Original Premises TI Allowance shall be permanently reduced by the 7^th Floor Reallocated TI Allowance Amount, and Landlord shall have no further obligation to fund the 7^th Floor Reallocated TI Allowance Amount for the Tenant Improvements for the Original Premises.

(d) Excess Costs. Tenant shall be solely responsible for any costs related to the 7^th Floor Tenant Improvements in excess of the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right and subject to Landlord’s obligations under Section 2.3(a) of the 7^th Floor Work Letter regarding costs incurred with respect to any Change (as defined in the 7^th Floor Work Letter) requested by Landlord) (the “7^th Floor Excess Costs”). If the amount of the Approved Budget (as defined in the 7^th Floor Work Letter) is greater than the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right), but less than or equal to one hundred ten percent (110%) of the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right), then Landlord shall first pay the entire 7^th Floor TI Allowance, and after the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right) has been expended, Tenant shall pay the 7^th Floor Excess Costs. If the amount of the Approved Budget exceeds one hundred ten percent (110%) of the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right), then Tenant shall deposit an amount equal to the 7^th Floor Excess Costs with Landlord no less than ten (10) Business Days before commencing work on the 7^th Floor Tenant Improvements. In such case, Tenant’s funds shall be disbursed by Landlord on a pari pasu basis with the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right) as set forth in the 7^th Floor Work Letter. Following disbursement of the 7^th Floor TI Allowance (as the same may be adjusted pursuant to the 7^th Floor TI Allowance Reallocation Right) and any Tenant funds deposited with Landlord, Tenant shall pay for all remaining costs (excluding costs that are Landlord’s obligation under Section 2.3(a) of the 7^th Floor Work Letter) for the 7^th Floor Tenant Improvements within ten (10) Business Days after written notice from Landlord of the amount due from Tenant. At the option of Landlord, amounts payable by Tenant pursuant to this paragraph shall be paid directly to Tenant’s contractor or such other party as Landlord may reasonably designate in writing.

(e) Early Access. Tenant will be granted access to the 7^th Floor Premises for the purpose of constructing the 7^th Floor Tenant Improvements and the placement of personal property in the 7^th Floor Premises, provided that prior to entering upon the 7^th Floor Premises, Tenant shall furnish to Landlord evidence satisfactory to Landlord that insurance coverages required of Tenant under the provisions of Article 23 of the Existing Lease are in effect. Any such entry shall be subject to all the terms and conditions of this Lease, provided that Tenant’s obligation to pay Rent or utilities for the 7^th Floor Premises shall not commence until the 7th Floor Term Commencement Date.

(f) Selection of Laborers. With respect to the 7^th Floor Tenant Improvements, Landlord and Tenant shall mutually agree upon the selection of the architect, engineer, general contractor and major subcontractors, and Landlord and Tenant shall each participate in the review of the competitive bid process. Landlord shall not unreasonably withhold its consent, but may refuse to approve any architects, consultants, contractors, subcontractors or material suppliers that Landlord reasonably believes could cause labor disharmony or may not have sufficient experience, in Landlord’s reasonable opinion, to perform work in an occupied Class “A” laboratory research building. Landlord hereby consents to Tenant engaging Xxxxxx Construction Company as the general contractor and SABA Architects as the architect for the 7^th Floor Tenant Improvements, to the extent Tenant elects to engage such parties in such capacities.

9.Condition of 7^th Floor Premises. Tenant acknowledges that (a) it is fully familiar with the condition of the 7^th Floor Premises and agrees to take the same in its condition “as is” as of the Amendment Execution Date, subject only to Landlord’s obligations under the Lease (including but not limited to Landlord’s obligations under this Section 9), and (b) Landlord shall have no obligation to alter, repair or otherwise prepare the 7^th Floor Premises for Tenant’s occupancy for the 7^th Floor Premises Term or to pay for any improvements to the 7^th Floor Premises, except with respect to the 7^th Floor TI Allowance, the 7^th Floor Test Fit Allowance and as otherwise expressly stated in the Lease. Notwithstanding anything to the contrary, at Landlord’s sole cost and expense, Landlord shall deliver the 7^th Floor Premises to Tenant with the work to be performed by Landlord as described in the attached Exhibit D completed (the cost of which work shall not be deducted from the 7^th Floor TI Allowance or passed through as an Operating Expense, whether completed before or after Tenant takes possession of the 7^th Floor Premises) (such obligation, “Landlord’s Delivery Obligation”). Tenant’s taking possession of the 7^th Floor Premises shall, except as otherwise agreed to in writing by Landlord and Tenant, conclusively establish that the 7^th Floor Premises, the Building and the Project were at such time in good, sanitary and satisfactory condition and repair and that Landlord’s Delivery Obligation was satisfied; provided that, if Landlord fails to satisfy Landlord’s Delivery Obligation (a “Delivery Shortfall”), then Tenant may, as its sole and exclusive remedy, deliver notice of such failure to Landlord detailing the nature of such failure (a “Shortfall Notice”); provided, further, that any Shortfall Notice must be received by Landlord no later than the date (the “Shortfall Notice Deadline”) that is thirty (30) days after the Amendment Execution Date. In the event that Landlord receives a Shortfall Notice on or before the Shortfall Notice Deadline, Landlord shall, at Landlord’s expense, promptly remedy the Delivery Shortfall. Landlord shall not have any obligations or liabilities in connection with a failure to satisfy Landlord’s Delivery Obligation except to the extent such failure is identified by Tenant in a Shortfall Notice delivered to Landlord on or before the Shortfall Notice Deadline. Notwithstanding anything to the contrary, Landlord shall deliver the 7^th Floor Premises to Tenant free and clear of any Hazardous Materials in violation of Applicable Laws to the extent in effect and as interpreted and applied as of the Amendment Execution Date.

10.6^th Floor Right of First Offer. Tenant acknowledges that Landlord is in active negotiations to lease the premises comprising approximately 19,370 square feet of Rentable Area on the sixth (6^th) floor of the Building (the “Active Negotiation Premises”) to another prospective tenant. Upon the full execution and delivery of a lease for all of the Active Negotiation Premises with another prospective tenant, which is the first lease for all of the Active Negotiation Premises to be executed and delivered after the Amendment Effective Date (the “Active Negotiations Premises Lease”), then subject and subordinate to any rights of (a) the tenant under such Active Negotiations Premises Lease, and (b) any other parties’ pre-existing rights (based on written contracts executed prior to the Amendment Execution Date), for so long as Tenant continues to lease and occupy one hundred percent (100%) of both the Premises and the Adjacent Building Premises, Tenant shall have a continuing right of first offer (“ROFO”) as to any rentable premises on the sixth (6^th) floor of the Building for which Landlord is seeking a tenant (“Available ROFO Premises”); provided, however, that in no event shall Landlord be required to lease any Available ROFO Premises to Tenant for any period past the date on which the Lease expires or is terminated pursuant to its terms. Notwithstanding the foregoing, to the extent that Landlord renews or extends a then-existing lease with any then-existing tenant of any space or enters into a new lease with such then-existing tenant (including but not limited to the tenant under the Active Negotiations Premises Lease), the affected space shall not be deemed to be Available ROFO Premises. In the event Landlord intends to market Available ROFO Premises, Landlord shall provide written notice thereof to Tenant, which notice shall include the terms and conditions on which Landlord intends to offer the Available ROFO Premises (the “Notice of Marketing”).

(a) Within ten (10) Business Days following its receipt of a Notice of Marketing, Tenant shall advise Landlord in writing whether Tenant elects to lease all (not just a portion) of the Available ROFO Premises on the terms and conditions set forth in the Notice of Marketing. If Tenant fails to notify Landlord of Tenant’s election within such ten (10) Business Day period, then Tenant shall be deemed to have elected not to lease the Available ROFO Premises.

(b) If Tenant timely notifies Landlord that Tenant elects to lease all of the Available ROFO Premises on the terms and conditions set forth in the Notice of Marketing, then Landlord shall lease the Available ROFO Premises to Tenant upon the terms and conditions set forth in the Notice of Marketing.

(c) If (i) Tenant notifies Landlord that Tenant elects not to lease the Available ROFO Premises, or (ii) Tenant fails to notify Landlord of Tenant’s election within the ten (10) Business Day period described above, then Landlord shall have the right to consummate a lease of the Available ROFO Premises at base rent and concessions (including without limitation tenant allowances and brokerage commissions) not less than ninety-five percent (95%) of that stated in the Notice of Marketing, if applicable. If Landlord fails to so consummate a lease of the Available ROFO Premises within six (6) months after the date of the Notice of Marketing, then Landlord must again offer the Available ROFO Premises to Tenant pursuant to the terms of this Article prior to leasing the Available ROFO Premises to a third party.

(d) Notwithstanding anything in this Section to the contrary, Tenant may not exercise the ROFO during such period of time that Tenant is in default under any provision of the Lease beyond applicable notice and cure periods. Any attempted exercise of the ROFO during a period of time in which Tenant is so in default beyond applicable notice and cure periods shall be void and of no effect. In addition, Tenant shall not be entitled to exercise the ROFO if Tenant has defaulted (beyond applicable notice and cure periods) in the performance of either a material monetary obligation or material non-monetary obligation under the Lease two (2) or more times during the Term or Option Term (as applicable).

(e) Notwithstanding anything in this Amendment or the Lease to the contrary, Tenant shall not assign or transfer the ROFO to a party other than a Tenant’s Affiliate, either separately or in conjunction with an assignment or transfer of Tenant’s interest in the Lease, without Landlord’s prior written consent, which consent Landlord may withhold in its sole and absolute discretion.

(f) If Tenant exercises the ROFO, Landlord does not guarantee that the Available ROFO Premises will be available on the anticipated commencement date for the Lease as to such Premises due to a holdover by the then-existing occupants of the Available ROFO Premises or for any other reason beyond Landlord’s reasonable control.

(g) This ROFO shall remain in effect until the Available ROFO Premises has been leased by Tenant or a third party, or until the Lease has expired, at which time this ROFO shall terminate and be of no force and effect. If the Available ROFO Premises (or any portion thereof) is leased to a third party, and such third party lease subsequently expires or is otherwise terminated, Tenant’s ROFO shall be reinstituted.

11.State Tax Incentives. Upon Tenant’s written request, Landlord agrees to reasonably cooperate with Tenant, at no cost or liability to Landlord, with respect to Tenant’s application to the Revenue Department for certain tax benefits pursuant to the Sales Tax Deferral and the application of such benefits to the construction of the 7^th Floor Tenant Improvements, all in accordance with Article 45 of the Existing Lease.

12.Broker. Each party represents and warrants to the other party that it has not dealt with any broker or agent in the negotiation for or the obtaining of this Amendment, other than Xxxxx Xxxxxxxx (“Broker”). Each party agrees to reimburse, indemnify, save, defend (at the other party’s option and with counsel reasonably acceptable to the other party) and hold harmless the other party for, from and against any and all cost or liability for compensation claimed by any such broker or agent, other than Broker, employed or engaged by the party or claiming to have been employed or engaged as a result the party’s own acts. Broker is entitled to a leasing commission in connection with the making of this Amendment, and Landlord shall pay such commission to Broker pursuant to a separate agreement between Landlord and Broker.

13.No Default. Tenant represents, warrants and covenants that, to the best of Tenant’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the Existing Lease and no event has occurred that, with the passage of time or the giving of notice (or both) would constitute a default by either Landlord or Tenant thereunder. Landlord represents, warrants and covenants that, to the best of Landlord’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the Existing Lease and no event has occurred that, with the passage of time or the giving of notice (or both) would constitute a default by either Landlord or Tenant thereunder.

14.Effect of Amendment. Except as modified by this Amendment, the Existing Lease and all the covenants, agreements, terms, provisions and conditions thereof shall remain in full force and effect and are hereby ratified and affirmed. In the event of any conflict between the terms contained in this Amendment and the Existing Lease, the terms herein contained shall supersede and control the obligations and liabilities of the parties.

15.Successors and Assigns. Each of the covenants, conditions and agreements contained in this Amendment shall inure to the benefit of and shall apply to and be binding upon the parties hereto and their respective heirs, legatees, devisees, executors, administrators and permitted successors and assigns and sublessees. Nothing in this section shall in any way alter the provisions of the Lease restricting assignment or subletting.

16.Miscellaneous. This Amendment becomes effective only upon execution and delivery hereof by Landlord and Tenant. The captions of the paragraphs and subparagraphs in this Amendment are inserted and included solely for convenience and shall not be considered or given any effect in construing the provisions hereof. All exhibits hereto are incorporated herein by reference. Submission of this instrument for examination or signature by Tenant does not constitute a reservation of or option for a lease, and shall not be effective as a lease, lease amendment or otherwise until execution by and delivery to both Landlord and Tenant.

17.Authority. Each party guarantees, warrants and represents to the other that the individual or individuals signing this Amendment on its behalf have the power, authority and legal capacity to sign this Amendment on behalf of and to bind all entities, corporations, partnerships, limited liability companies, joint venturers or other organizations and entities on whose behalf such individual or individuals have signed.

18.Counterparts; Facsimile and PDF Signatures. This Amendment may be executed in one or more counterparts, each of which, when taken together, shall constitute one and the same document. A facsimile or portable document format (PDF) signature on this Amendment shall be equivalent to, and have the same force and effect as, an original signature.

Tenant shall prepare the Schedule so that it is a reasonable schedule for the completion of the 7^th Floor Tenant Improvements. As soon as the Schedule is completed, Tenant shall deliver the same to Landlord for Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Such Schedule shall be approved or disapproved by Landlord within ten (10) Business Days after delivery to Landlord. Landlord’s failure to respond within such ten (10) Business Day period shall be deemed approval by Landlord. If Landlord disapproves the Schedule, then Landlord shall notify Tenant in writing of its objections to such Schedule, and the parties shall confer and negotiate in good faith to reach agreement on the Schedule. The Schedule shall be subject to adjustment as mutually agreed upon in writing by the parties, or as provided in this Work Letter.

The non-requesting party’s failure to respond within such five (5) Business Day period shall be deemed approval by the non-requesting party.

2.4 Preparation of Estimates. Tenant shall, before proceeding with any Change, using its best efforts, prepare as soon as is reasonably practicable (but in no event more than seven (7) Business Days after delivering a Change Request to Landlord or receipt of a Change Request) an estimate of the increased costs or savings that would result from such Change, as well as an estimate on such Change’s effects on the Schedule. Landlord shall have five (5) Business Days after receipt of such information from Tenant to (a) in the case of a Tenant-initiated Change Request, approve or reject such Change Request in writing, or (b) in the case of a Landlord-initiated Change Request, notify Tenant in writing of Landlord’s decision either to proceed with or abandon the Landlord-initiated Change Request.

Tenant agrees to pay any deductible, and Landlord is not responsible for any deductible, for a claim under such insurance, except to the extent caused by Landlord’s negligence or intentional misconduct.

(a)Tenant shall have expended all of the 7^th Floor TI Allowance;

(b)No later than the TI Deadline for the Original Premises TI Allowance, Tenant shall have delivered to Landlord a written request to reallocate a portion of the unused Original Premises TI Allowance to pay the remaining cost to complete the construction of the 7^th Floor Tenant Improvements, setting forth the amount of the Original Premises TI Allowance that Tenant desires to reallocate (the “7^th Floor Reallocated TI Allowance Amount”); and
