B. WHEREAS, Landlord and Tenant desire to extend the Term of the Existing Lease; and

C. WHEREAS, Landlord and Tenant desire to modify and amend the Existing Lease only in the respects and on the conditions hereinafter stated.

AGREEMENT

NOW, THEREFORE, Landlord and Tenant, in consideration of the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, agree as follows:

1. Definitions . For purposes of this Amendment, capitalized terms shall have the meanings ascribed to them in the Existing Lease unless otherwise defined herein. The Existing Lease, as amended by this Amendment, is referred to collectively herein as the “ Lease .” From and after the date hereof, the term “ Lease ,” as used in the Existing Lease, shall mean the Existing Lease, as amended by this Amendment.

2. Extension Term . The Term of the Lease is hereby extended for sixty-five (65) months and, therefore, the Term Expiration Date is hereby amended to mean August 31, 2024. Notwithstanding that, prior to this Amendment, the Term of the Existing Lease was scheduled to expire on March 31, 2019, the period commencing on September 1, 2017 (the “ Extension Term Commencement Date ”) and ending on the Term Expiration Date shall be referred to herein as the “ Extension Term .”

3. Condition of Premises . Tenant acknowledges that (a) it is in possession of and is fully familiar with the condition of the Premises and, notwithstanding anything contained in the Lease to the contrary, agrees to take the same in its condition “as is” as of the Extension Term Commencement Date, and (b) Landlord shall have no obligation to alter, repair or otherwise prepare the Premises for Tenant’s continued occupancy for the Extension Term or to pay for any improvements to the Premises, except with respect to payment of the TI Allowance (as defined below) and completion of the Roof Work (as defined below).

4. Basic Annual Rent . Notwithstanding anything to the contrary in the Existing Lease, during the Extension Term, Basic Annual Rent for the Premises shall be as set forth in the following table:

5. Phase II Basic Annual Rent Abatement . Tenant’s obligations with respect to Basic Annual Rent as to the Premises shall be subject to abatement in the amount of One Hundred Eight Thousand Three Hundred Eighty-Three and 10/100 Dollars ($108,383.10) (the “ Phase II Basic Annual Rent Abatement ”), which Phase II Basic Annual Rent Abatement shall be amortized and applied in equal installments over months one (1) through six (6) of the Extension Term (i.e., September 1, 2017 through February 28, 2018); provided , however, that Tenant shall not be entitled to any portion of the Phase II Basic Annual Rent Abatement accruing during a period of time in which Tenant is in Default under the Lease. Tenant acknowledges and agrees that the Phase II Basic Annual Rent Abatement has been granted to Tenant as additional consideration for entering into this Amendment and for agreeing to pay the Rent and perform all of the obligations of Tenant under the Lease. The Phase II Basic Annual Rent Abatement shall not work to abate or reduce Tenant’s obligations under the Lease with respect to Additional Rent including (without limitation) Tenant’s obligations with respect to Insurance Costs, Taxes and the Property Management Fee. For avoidance of doubt, for the first six (6) months of the Extension Term, the Property Management Fee shall be calculated as if Tenant were paying One Hundred Thirty-Six Thousand One Hundred Ninety and 60/100 Dollars ($136,190.60) per month for Base Rent.

2

6. Phase III Basic Annual Rent Abatement . In addition to the Phase II Basic Annual Rent Abatement, Tenant’s obligations with respect to Basic Annual Rent as to the Premises shall be subject to abatement in the amount of One Hundred Sixty-Seven Thousand One Hundred Sixty-Eight and 40/100 Dollars ($167,168.40) (the “ Phase III Basic Annual Rent Abatement ”), which Phase III Basic Annual Rent Abatement shall be amortized and applied in equal installments over months one (1) through twelve (12) of the Extension Term (i.e., September 1, 2017 through August 31, 2018); provided , however, that Tenant shall not be entitled to any portion of the Phase III Basic Annual Rent Abatement accruing during a period of time in which Tenant is in Default under the Lease. Tenant acknowledges and agrees that the Phase III Basic Annual Rent Abatement has been granted to Tenant as additional consideration for entering into this Amendment and for agreeing to pay the Rent and perform all of the obligations of Tenant under the Lease. The Phase III Basic Annual Rent Abatement shall not work to abate or reduce Tenant’s obligations under the Lease with respect to Additional Rent including (without limitation) Tenant’s obligations with respect to Insurance Costs, Taxes and the Property Management Fee. For avoidance of doubt, for the first twelve (12) months of the Extension Term, the Property Management Fee shall be calculated as if Tenant were paying One Hundred Thirty-Six Thousand One Hundred Ninety and 60/100 Dollars ($136,190.60) per month for Base Rent.

7. Tenant Improvements . Tenant shall cause the work (the “ Tenant Improvements ”) described in the Work Letter attached hereto as Exhibit A (the “ Work Letter ”) to be constructed in that certain portion of the Premises consisting of approximately forty-two thousand five hundred twenty-nine (42,529) square feet of Rentable Area (as more particularly described on Exhibit B-1 attached hereto, the “ Phase I Premises ”) at a cost to Landlord not to exceed Nine Hundred Seventy-Five Thousand Dollars ($975,000) (the “ TI Allowance ”).

7.1 The TI Allowance may be applied to the costs of (a) construction, (b) project review by Landlord (which fee shall equal three percent (3%) of the cost of the Tenant Improvements, including the TI Allowance), (c) 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, (d) space planning, architect, engineering and other related services performed by third parties unaffiliated with Tenant, (e) building permits and other taxes, fees, charges and levies by Governmental Authorities for permits or for inspections of the Tenant Improvements, and (f) costs and expenses for labor, material, equipment and fixtures. In no event shall the TI Allowance be used for (u) the cost of any work to space located outside of the Phase I Premises, (v) the cost of work that is not authorized by the Approved Plans (as defined in the Work Letter) or otherwise approved in writing by Landlord, (w) payments to Tenant or any affiliates of Tenant, (x) the purchase of any furniture, personal property or other non-building system equipment, (y) costs arising 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).

3

7.2 Tenant shall have until the date that is twelve (12) months after the Seventh Amendment Execution Date (such date, the “ TI Deadline ”), to submit Fund Requests (as defined in the Work Letter) to Landlord for disbursement of the unused portion of the TI Allowance, after which date Landlord’s obligation to fund any such costs for which Tenant has not submitted a Fund Request to Landlord shall expire. In no event shall any unused TI Allowance entitle Tenant to a credit against Rent payable under the Lease.

7.3 Following substantial completion of the Tenant Improvements, Tenant shall deliver to Landlord a Certificate of Substantial Completion in the form of the American Institute of Architects document G704, executed by the project architect and the general contractor.

8. Option to Extend Term . Tenant shall have the option (“ Option ”) to extend the Term by sixty (60) months as to the entire Premises (and no less than the entire Premises) upon the following terms and conditions. Any extension of the Term pursuant to the Option shall be on all the same terms and conditions as the Lease, except as follows:

8.1 Base Rent at the commencement of the Option term shall equal the then-current fair market value for comparable office and laboratory space in the Newark/Fremont submarket of comparable age, quality, level of finish and proximity to amenities and public transit, and containing the systems and improvements present in the Premises as of the date that Tenant gives Landlord written notice of Tenant’s election to exercise the Option (“ FMV ”), and shall be further increased on each annual anniversary of the Option term commencement date by three percent (3%). Tenant may, no more than twelve (12) months prior to the date the Term is then scheduled to expire, request Landlord’s estimate of the FMV for the Option term. Landlord shall, within fifteen (15) days after receipt of such request, give Tenant a written proposal of such FMV. If Tenant gives written notice to exercise the Option, such notice shall specify whether Tenant accepts Landlord’s proposed estimate of FMV. If Tenant does not accept the FMV, then the parties shall endeavor to agree upon the FMV, taking into account all relevant factors, including (a) the size of the Premises, (b) the length of the Option term, (c) rent in comparable buildings in the relevant submarket, including concessions offered to new tenants, such as free rent, tenant improvement allowances and moving allowances, (d) Tenant’s creditworthiness and (e) the quality and location of the Building and the Property. In the event that the parties are unable to agree upon the FMV within thirty (30) days after Tenant notifies Landlord that Tenant is exercising the Option, then either party may request that the same be determined as follows: a senior officer of a nationally recognized leasing brokerage firm with local knowledge of the Newark/Fremont laboratory/research and development leasing submarket (the “ Baseball Arbitrator ”) shall be selected and paid for jointly by Landlord and Tenant. If Landlord and Tenant are unable to agree upon the Baseball Arbitrator, then the same shall be designated by the local chapter of the Judicial Arbitration and Mediation Services or any successor organization thereto (the “ JAMS ”). The Baseball Arbitrator selected by the parties or designated by JAMS shall (aa) have at least ten (10) years’ experience in the leasing of laboratory/research and development space in the Newark/Fremont submarket and (bb) not have been employed or retained by either Landlord or Tenant or any affiliate of either for a period of at least ten (10) years prior to appointment pursuant hereto. Each of Landlord and Tenant shall submit to the Baseball Arbitrator and to the other party its determination of the FMV. The Baseball

4

Arbitrator shall grant to Landlord and Tenant a hearing and the right to submit evidence. The Baseball Arbitrator shall determine which of the two (2) FMV determinations more closely represents the actual FMV. The arbitrator may not select any other FMV for the Premises other than one submitted by Landlord or Tenant. The FMV selected by the Baseball Arbitrator shall be binding upon Landlord and Tenant and shall serve as the basis for determination of Base Rent payable for the Option term. If, as of the commencement date of the Option term, the amount of Base Rent payable during the Option term shall not have been determined, then, pending such determination, Tenant shall pay Base Rent equal to the Base Rent payable with respect to the last year of the then-current Term. After the final determination of Base Rent payable for the Option term, the parties shall promptly execute a written amendment to the Lease specifying the amount of Base Rent to be paid during the Option term. Any failure of the parties to execute such amendment shall not affect the validity of the FMV determined pursuant to this Section.

8.2 The Option is not assignable separate and apart from the Lease.

8.3 The Option is conditional upon Tenant giving Landlord written notice of its election to exercise the Option at least twelve (12) months prior to the end of the expiration of the then-current Term. Time shall be of the essence as to Tenant’s exercise of the Option. Tenant assumes full responsibility for maintaining a record of the deadlines to exercise the Option. Tenant acknowledges that it would be inequitable to require Landlord to accept any exercise of the Option after the date provided for in this Section.

8.4 Notwithstanding anything contained in this Article to the contrary, Tenant shall not have the right to exercise the Option:

(a) During the time commencing from the date Landlord delivers to Tenant a written notice that Tenant is in default under any provisions of the Lease and continuing until Tenant has cured the specified default to Landlord’s reasonable satisfaction; or

(b) At any time after any Default as described in Article 24 of the Original Lease ( provided , however, that, for purposes of this Section 8.4(b) , Landlord shall not be required to provide Tenant with notice of such Default) and continuing until Tenant cures any such Default, if such Default is susceptible to being cured; or

(c) In the event that Landlord has given Tenant written notice that Tenant has defaulted in the performance of its obligations under the Lease more than two (2) times during the twelve (12)-month period immediately prior to the date that Tenant intends to exercise the Option, whether or not Tenant has cured such defaults.

8.5 The period of time within which Tenant may exercise the Option shall not be extended or enlarged by reason of Tenant’s inability to exercise such Option because of the provisions of Section 8.4 .

8.6 All of Tenant’s rights under the provisions of the Option shall terminate and be of no further force or effect even after Tenant’s due and timely exercise of the Option if, after such exercise, but prior to the commencement date of the new term, (a) Tenant fails to pay

5

to Landlord a monetary obligation of Tenant for a period of twenty (20) days after written notice from Landlord to Tenant, (b) Tenant fails to commence to cure a default (other than a monetary default) within thirty (30) days after the date Landlord gives notice to Tenant of such default or (c) Tenant has defaulted under the Lease two (2) or more times and a service or late charge under Section 24.1 of the Original Lease has become payable for any such default, whether or not Tenant has cured such defaults.

9. Existing Lease Terms . Notwithstanding anything to the contrary in the Lease, Article 2 of the Sixth Amendment and Article 3 of the Fifth Amendment are hereby deleted in their entirety and shall no longer be of any further force or effect.

10. Security Deposit . On or before the Seventh Amendment Execution Date, Tenant shall deposit with Landlord an amount equal to One Hundred Sixty Thousand Dollars ($160,000) to be held by Landlord as an additional Security Deposit under the Lease in accordance with all of the terms, conditions and provisions of Article 9 of the Original Lease. From and after the Seventh Amendment Execution Date, the required Security Deposit under the Lease shall be an amount equal to Three Hundred Thousand Dollars ($300,000).

11. Roof Work . On or before the date that is five ( 5) months after the Seventh Amendment Execution Date, Landlord shall perform certain repair and/or replacement work to the roof of the Building as deemed necessary by Landlord to put the roof in good watertight condition (such work, the “ Roof Work ”). Notwithstanding anything to the contrary in the Existing Lease, Tenant shall (as Additional Rent) reimburse Landlord for all costs and expenses paid or incurred by Landlord in connection with the Roof Work amortized over the Extension Term, with such reimbursement to be made by Tenant in equal monthly payments on the first day of each calendar month during the Extension Term.

12. Phase II Premises Sublease .

12.1 If (a) Tenant enters into a sublease with respect to all of that certain space containing approximately Seven Thousand Three Hundred Seventy-Three (7,373) square feet of Rentable Area (as more particularly described on Exhibit B-2 attached hereto, the “ Phase II Premises ”), and (b) Landlord consents to such sublease in accordance with the terms, conditions and provisions of the Existing Lease (any such sublease meeting the requirements of (a) and (b) above, an “ Approved Phase II Premises Sublease ”), then Section 25.4(d) of the Original Lease shall not apply to such Approved Phase II Premises Sublease.

12.2 In the event that (a) Tenant enters into an Approved Phase II Premises Sublease on or before the TI Deadline, (b) Landlord consents to such Approved Phase II Premises Sublease on or before the TI Deadline, and (c) such Approved Phase II Premises Sublease is an arms-length transaction with a subtenant that is not affiliated with Tenant in any respect, the TI Allowance (as defined in Article 7 ) shall automatically be increased by an amount equal to One Hundred Twenty-Five Thousand Dollars ($125,000) (such additional portion of the TI Allowance, the “ Phase II Premises TI Allowance ”); provided , however, that the Phase II Premises TI Allowance shall only be applied to the cost of Tenant Improvements performed in the Phase II Premises. For avoidance of doubt, the Phase II Premises TI Allowance shall be

6

subject to all of the terms, conditions and provisions of this Amendment (and the Work Letter) applicable to the TI Allowance (including, without limitation, the TI Deadline), except that the Phase II Premises TI Allowance shall only be applied to the cost of Tenant Improvements performed in the Phase II Premises.

13. Broker . Tenant represents and warrants that it has not dealt with any broker or agent in the negotiation for or the obtaining of this Amendment, other than Kidder Mathews (“ Broker ”), and agrees to reimburse, indemnify, save, defend (at Landlord’s option and with counsel reasonably acceptable to Landlord, at Tenant’s sole cost and expense) and hold harmless Landlord and its affiliates, and their respective employees, agents, contractors and lenders, 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 it or claiming to have been employed or engaged by it. 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.

14. 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.

WORK LETTER

This Work Letter (this “ Work Letter ”) is made and entered into as of the 30 ^th day of May, 2017, by and between BMR-34790 ARDENTECH COURT LP, a Delaware limited partnership (“ Landlord ”), and ZP OPCO, INC., a Delaware corporation (“ Tenant ”), and is attached to and made a part of that certain Seventh Amendment to Lease dated of even date herewith (as the same may be amended, amended and restated, supplemented or otherwise modified from time to time, the “ Amendment ”), by and between Landlord and Tenant for the Premises located at 34790 Ardentech Court in Fremont, California. All capitalized terms used but not otherwise defined herein shall have the meanings given them in the Amendment.

1. General Requirements .

1.1. Authorized Representatives .

(a) Landlord designates, as Landlord’s authorized representative (“ Landlord’s Authorized Representative ”), (i) Ben Evans as the person authorized to initial plans, drawings, approvals and to sign change orders pursuant to this Work Letter and (ii) an officer of Landlord as the person authorized to sign any amendments to this Work Letter or the Lease. Tenant shall not be obligated to respond to or act upon any such item until such item has been initialed or signed (as applicable) by the appropriate Landlord’s Authorized Representative. Landlord may change either Landlord’s Authorized Representative upon one (1) business day’s prior written notice to Tenant.

(b) Tenant designates Georgia Erbez (“ Tenant’s Authorized Representative ”) as the person authorized to initial and sign all plans, drawings, change orders and approvals pursuant to this Work Letter. Landlord shall not be obligated to respond to or act upon any such item until such item has been initialed or signed (as applicable) by Tenant’s Authorized Representative. Tenant may change Tenant’s Authorized Representative upon one (1) business day’s prior written notice to Landlord.

1.2. Schedule . The schedule for design and development of the Tenant Improvements, including the time periods for preparation and review of construction documents, approvals and performance, shall be in accordance with a schedule to be prepared by Tenant (the “ Schedule ”). Tenant shall prepare the Schedule so that it is a reasonable schedule for the completion of the Tenant Improvements. The Schedule shall clearly identify all activities requiring Landlord participation, including specific dates and time periods when Tenant’s contractor will require access to areas of the Property outside of the Premises. 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.

1.3. Tenant’s Architects, Contractors and Consultants . The architect, engineering consultants, design team, general contractor and subcontractors responsible for the construction of the Tenant Improvements shall be selected by Tenant and approved by Landlord, which approval Landlord shall not unreasonably withhold, condition or delay. Landlord may refuse to use 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 and in tenant-occupied lab areas. All Tenant contracts related to the Tenant Improvements shall provide that Tenant may assign such contracts and any warranties with respect to the Tenant Improvements to Landlord at any time.

2. Tenant Improvements . All Tenant Improvements shall be performed by Tenant’s contractor, at Tenant’s sole cost and expense (subject to Landlord’s obligations with respect to any portion of the TI Allowance) and in accordance with the Approved Plans (as defined below), the Amendment and this Work Letter. To the extent that the total projected cost of the Tenant Improvements (as projected by Landlord) exceeds the TI Allowance (such excess, the “ Excess TI Costs ”), Tenant shall advance to Landlord any Excess TI Costs within ten (10) days after receipt of an invoice therefor, but in any case before Tenant commences the Tenant Improvements. If the actual Excess TI Costs are less than the Excess TI Costs paid by Tenant to Landlord, Landlord shall promptly return such excess to Tenant following completion of the Tenant Improvements. If the cost of the Tenant Improvements (as projected by Landlord) increases over Landlord’s initial projection, then Landlord may notify Tenant and Tenant shall deposit any additional Excess TI Costs with Landlord in the same way that Tenant deposited the initial Excess TI Costs. If Tenant fails to pay, or is late in paying, any sum due to Landlord under this Work Letter, then Landlord shall have all of the rights and remedies set forth in the Lease for nonpayment of Rent (including the right to interest and the right to assess a late charge), and for purposes of any litigation instituted with regard to such amounts the same shall be considered Rent. All material and equipment furnished by Tenant or its contractors as the Tenant Improvements shall be new or “like new;” the Tenant Improvements shall be performed in a first-class, workmanlike manner; and the quality of the Tenant Improvements shall be of a nature and character not less than the Building Standard. Tenant shall take, and shall require its contractors to take, commercially reasonable steps to protect the Premises during the performance of any Tenant Improvements, including covering or temporarily removing any window coverings so as to guard against dust, debris or damage. All Tenant Improvements shall be performed in accordance with Article 17 of the Original Lease; provided that, notwithstanding anything in the Lease or this Work Letter to the contrary, in the event of a conflict between this Work Letter and Article 17 of the Original Lease, the terms of this Work Letter shall govern.

2.1. Work Plans . Tenant shall prepare and submit to Landlord for approval schematics covering the Tenant Improvements prepared in conformity with the applicable provisions of this Work Letter (the “ Draft Schematic Plans ”). The Draft Schematic Plans shall contain sufficient information and detail to accurately describe the proposed design to Landlord and such other information as Landlord may reasonably request. Landlord shall not

unreasonably object to, or otherwise unreasonably withhold its approval of, the Draft Schematic Plans; provided , however, if the Draft Schematic Plans adversely affect (a) any structural portions of the Building, including exterior walls, the roof, the foundation or slab, foundation or slab systems (including barriers and subslab systems) or the core of the Building, (b) the exterior of the Building or (c) any Building systems, including elevator, plumbing, HVAC, electrical, security, life safety and power, then Landlord may raise objections to, and otherwise withhold its approval of, the Draft Schematic Plans in Landlord’s sole and absolute discretion. Landlord shall notify Tenant in writing within ten (10) business days after receipt of the Draft Schematic Plans whether Landlord approves or objects to the Draft Schematic Plans and of the manner, if any, in which the Draft Schematic Plans are unacceptable. Landlord’s failure to respond within such ten (10) business day period shall be deemed approval by Landlord. If Landlord objects to the Draft Schematic Plans, then Tenant shall revise the Draft Schematic Plans and cause Landlord’s objections to be remedied in the revised Draft Schematic Plans. Tenant shall then resubmit the revised Draft Schematic Plans to Landlord for approval. Landlord’s approval of or objection to revised Draft Schematic Plans and Tenant’s correction of the same shall be in accordance with this Section until Landlord has approved the Draft Schematic Plans in writing or been deemed to have approved them. The iteration of the Draft Schematic Plans that is approved or deemed approved by Landlord without objection shall be referred to herein as the “ Approved Schematic Plans .”

2.2. Construction Plans . Tenant shall prepare final plans and specifications for the Tenant Improvements that (a) are consistent with and are logical evolutions of the Approved Schematic Plans and (b) incorporate any other Tenant-requested (and Landlord-approved) Changes (as defined below). As soon as such final plans and specifications (“ Construction Plans ”) are completed, Tenant shall deliver the same to Landlord for Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. All such Construction Plans shall be submitted by Tenant to Landlord in electronic .pdf, CADD and full-size hard copy formats, and 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 the Construction Plans are disapproved by Landlord, then Landlord shall notify Tenant in writing of its objections to such Construction Plans, and the parties shall confer and negotiate in good faith to reach agreement on the Construction Plans. Promptly after the Construction Plans are approved by Landlord and Tenant, two (2) copies of such Construction Plans shall be initialed and dated by Landlord and Tenant, and Tenant shall promptly submit such Construction Plans to all appropriate Governmental Authorities for approval. The Construction Plans so approved, and all change orders specifically permitted by this Work Letter, are referred to herein as the “ Approved Plans .”

2.3. Changes to the Tenant Improvements . Any changes to the Approved Plans (each, a “ Change ”) shall be requested and instituted in accordance with the provisions of this Article 2 and shall be subject to the written approval of the non-requesting party in accordance with this Work Letter.

(a) Change Request . Either Landlord or Tenant may request Changes after Landlord approves the Approved Plans by notifying the other party thereof in writing in substantially the same form as the AIA standard change order form (a “ Change Request ”), which Change Request shall detail the nature and extent of any requested Changes, including (a) the Change, (b) the party required to perform the Change and (c) any modification of the Approved Plans and the Schedule, as applicable, necessitated by the Change. If the nature of a Change requires revisions to the Approved Plans or increases the cost of the Tenant Improvements, then the requesting party shall be solely responsible for the cost and expense of such revisions and any increases in the cost of the Tenant Improvements as a result of such Change. Change Requests shall be signed by the requesting party’s Authorized Representative. In the event that Tenant’s completion of the Tenant Improvements is actually delayed as a result of a Change Request submitted by Landlord in accordance with this Section, the Tl Deadline shall be extended by one (I) day for each day of any such delay(s).

(b) Approval of Changes . All Change Requests shall be subject to the other patty’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed. Subject to Section 2.4 below, the non-requesting party shall have five (5) business days after receipt of a Change Request to notify the requesting party in writing of the non-requesting party’s decision either to approve or object to the Change Request. 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 five (5) 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 of 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.

2.5. Quality Control Program; Coordination .
