It is further understood and agreed that in the event Landlord shall give its written consent to Tenant's making any such Alterations (as defined below) pursuant to Section 7 below, such written consent shall not be deemed to be an agreement or consent by Landlord to subject Landlord's interest in the Premises, the Complex or the land to any mechanic's or materialmen's liens which may be filed in respect of any such Alterations made by or on behalf of Tenant.

TENANT ALTERATIONS

A. Alterations. Landlord shall construct all of the Lease Improvements and Tenant Improvements, as defined in Exhibit “C”. Landlord shall pay an amount not to exceed Two Million Three Hundred and Sixty-Three Thousand Two Hundred Fifty and No/100 Dollars ($2,363,250.00) for the Tenant Improvements (the "Landlord Cap"). Tenant shall pay the cost of the Tenant Improvements in excess of the Landlord Cap, if any. Any costs of the Tenant Improvements over the Landlord Cap will, at the request of Tenant, up to One Million Five Hundred and Seventy-Five Thousand Five Hundred and No/100 Dollars ($1,575,500.00), be funded by Landlord and the amount shall be amortized over the Term at an interest rate of 0% per annum and such amortization amount shall be included by Tenant as a payment to Landlord along with the monthly Basic Rent payment (the "TI Deferred Payment"). The Lease Improvements and Tenant Improvements shall be performed by Landlord in accordance with Exhibit "C" attached hereto. Tenant will not make or permit anyone to make any material alterations, decorations, additions or improvements, structural or otherwise, in or to the Premises or the Complex, without the prior written consent of Landlord ("Alterations"), which shall not be unreasonably withheld, delayed, denied, or conditioned. All of such Alterations must conform to all applicable rules and regulations established from time to time by the Underwriters' Association of the local area and conform to all applicable requirements of the Federal, state and local governments, including any requirements or approvals set forth in Section 50 of this Lease. When granting its consent, Landlord may impose any conditions it deems reasonably appropriate, including, without limitation, approval of plans and specifications, selection of contractor and obtaining of specified insurance, provided the foregoing conditions are reasonable in nature.

B. Property of Landlord. All alterations, installations, changes, replacements, attached equipment, laboratory casework, built-in cabinet work sinks and related plumbing fixtures, laboratory benches, exterior venting fume hoods, additions to, or improvements in, including wall-to-wall carpet, upon the Premises (whether with or without the prior written consent of Landlord) shall, at the election of the Landlord (which election Landlord shall deliver in writing to Tenant at least 120 days prior to the expiration of the Term; and, if Landlord does not timely deliver such election to Tenant, Landlord will be deemed to have elected to waive its rights to designate property to be retained under this Section 7.B), remain upon the Premises, become property of the Landlord, and be surrendered with the Premises at the expiration or termination of this Lease or upon expiration of any renewal period hereof without disturbance, molestation or injury; provided, however, that if Tenant is not then in default in the performance of any of its obligations under this Lease, Tenant shall have the right (but not the obligation) to remove, during the 90-day period prior to the Lease Expiration Date, any of the foregoing items which Landlord does not wish to retain (or which Landlord is deemed to have waived its right to retain), together with all of Tenant's movable furniture, movable furnishings, or movable equipment, or trade fixtures purchased by Tenant at its sole cost and expense and within the Premises, at the expense of Tenant. If Tenant elects to so remove any such items from the Premises, Tenant agrees to repair all material damage to the Premises and the fixtures, appurtenances and equipment of the Landlord therein, and to the Complex caused by the Tenant's removal of its furniture, fixtures, equipment, machinery and the like and the removal of any improvements or alterations. Should the Tenant fail to repair all the above referred to damage, then, and in such event, the Landlord may repair the said damage at the Tenant's expense and the Tenant hereby agrees to reimburse the Landlord for such expense within 10 business days follow receipt of demand therefor.

Notwithstanding anything contained in this Lease to the contrary, Tenant shall have the exclusive use of the furniture, fixtures and equipment (“FF&E”) as more particularly described in the Donation Agreement; the FF&E shall not be removed or used in another location (but may be removed by Tenant from the Premises in the same manner as other property which Tenant is entitled to remove under this Section 7.B during the final 90 days of the Term).

C. Indemnification. Tenant will indemnify and hold Landlord, Landlord's mortgagees, and their respective employees, agents, tenants, invitees, licensees, affiliates, partners, members, shareholders, and principals (each a "Landlord Indemnified Party" and collectively, the "Landlord Indemnified Parties") harmless from and against any and all losses, liability, expenses, liens, claims or damages (each, a “Loss”) to person or property which occur during the Term of this Lease as a direct result of Tenant's alterations, decorations, additions or improvements, including without limitation, the Tenant Improvements or any Alteration, except to the extent any such Loss is caused by Landlord’s breach of its maintenance obligations under Section 5 of this Lease or Landlord’s willful misconduct. If any such alteration, decoration, addition or improvement is made without the prior written consent of Landlord and such Alteration is not permitted under this Lease, Landlord may correct or remove the same, and Tenant shall be liable for any and all reasonable expenses incurred by Landlord in the performance of this work.

SERVICES

Landlord shall furnish to Tenant during the Term of the Lease hot and cold water, electric current adequate for Tenant's proposed use of the Premises, and sanitary sewer services at those points of supply up to the demarcation of the Premises as set forth on Plans and Specifications (as hereinafter defined). Notwithstanding the foregoing, Landlord shall not be liable for failure to furnish or for suspension or delay in furnishing any of such services under this Section 8 caused by breakdown that is outside of Landlord's reasonable control, maintenance or repair work (to the extent outside of Landlord's reasonable control) or strike, riot, civil commotion, natural disaster, or pandemic. If, however, Tenant is prevented from using, and does not use, the Premises or access thereto because of the unavailability of any such service for a period of three (3) consecutive business days and such unavailability was within Landlord’s reasonable control, then Tenant shall, as its exclusive remedy be entitled to abatement of Basic Rent and Additional Rent for each day that Tenant is so prevented from using or accessing the Premises. Tenant shall be responsible for obtaining its own separately metered electricity, telephone, internet, and other desired services.

INSPECTION

Tenant will permit Landlord, or its agents or other representatives to enter the Premises with three (3) days written notice to Tenant except in the case of an emergency when Landlord may enter without notice and without charge therefor to Landlord and without diminution of the Rent payable by Tenant to examine, inspect and protect the Premises and the Complex and to make such alterations and/or repairs as in the judgment of the Landlord may be deemed reasonably necessary, or to exhibit the same to prospective tenants or purchasers during the Term of this Lease. Written notice shall include the names, employer, and purpose of the entry. Landlord acknowledges that the Premises must comply with various federal security requirements and that Tenant may prescribe additional requirements to comply with federal laws and maintain the integrity of the laboratory and other facilities within the Premises; Landlord shall comply with the foregoing at Tenant’s expense prior to entering the Premises.

10.

DAMAGE TO THE PREMISES OR COMPLEX

If a portion of the Premises or Complex shall be damaged by fire or other cause (a "Casualty"), Landlord shall, within 60 days after such Casualty, deliver to Tenant a good faith estimate (the "Damage Notice") of the time needed to repair the damage caused by such Casualty use best efforts to repair such damage at the expense of the Landlord.

A. Tenant’s Rights. If the Premises or the Complex are damaged by Casualty such that Tenant is prevented from conducting its business in the Premises in a manner reasonably comparable to that conducted immediately before such Casualty and Landlord reasonably estimates that the damage caused thereby for which Landlord is responsible to repair under this Lease pursuant to Section 10.C below cannot be repaired within 270 days after the commencement of repairs (the "Repair Period"), then Tenant may terminate this Lease by delivering written notice to Landlord of its election to terminate within 30 days after the Damage Notice has been delivered to Tenant.

B. Landlord’s Rights. If a Casualty occurs and (1) Landlord estimates that the damage cannot be repaired within the Repair Period, (2) the damage exceeds 50% of the replacement cost thereof (excluding foundations and footings), as estimated by Landlord, and such damage occurs during the last two years of the Term, (3) regardless of the extent of damage, the damage is not fully covered by Landlord’s insurance policies or Landlord makes a good faith determination, after considering the availability of insurance proceeds, that restoring the damage would be uneconomical, or (4) Landlord is required to pay any insurance proceeds arising out of the Casualty to Landlord’s mortgagee, then Landlord may terminate this Lease by giving written notice of its election to terminate within 30 days after the Damage Notice has been delivered to Tenant.

C. Repair Obligation. If neither party elects to terminate this Lease following a Casualty, then Landlord shall, within a reasonable time after such Casualty, begin to repair the Premises and shall proceed with reasonable diligence to restore the Premises to substantially the same condition as they existed immediately before such Casualty; however, except for the Landlord Work, Landlord shall not be required to repair or replace any improvements, alterations or betterments within the Premises (which shall be promptly and with due diligence repaired and restored by Tenant at Tenant’s sole cost and expense) or any furniture, equipment, trade fixtures or personal property of Tenant or others in the Premises or the Complex, and Landlord’s obligation to repair or restore the Premises shall be limited to the extent of the insurance proceeds actually received by Landlord for the Casualty in question. Landlord shall be entitled to the full proceeds of the insurance policies providing coverage for all alterations, improvements and betterments in the Premises (and, if Tenant has failed to maintain insurance on such items as required by this Lease, Tenant shall pay Landlord an amount equal to the proceeds Landlord would have received had Tenant maintained insurance on such items as required by this Lease); for the avoidance of doubt, notwithstanding anything contained herein to the contrary, Tenant shall be entitled to the full proceeds of the insurance policies that Tenant maintains under Section 11.D, below.

D. Abatement of Rent. If the Premises are damaged by Casualty, Basic Rent and Additional Rent for the portion of the Premises rendered untenantable by the damage shall be abated on a reasonable basis from the date of damage until the earlier of (1) completion of Landlord’s repairs, (2) the date upon which completion of Landlord’s repairs would have occurred but for delays caused by Tenant Parties, or (3) the date of termination of this Lease by Landlord or Tenant as provided above, as the case may be, unless a Tenant Party caused such damage, in which case, Tenant shall continue to pay Basic Rent and Additional Rent without abatement. In the event that damage to the Premises or to the Complex is caused by the negligence or willful misconduct of Tenant or its agents, employees or invitees, any cost or expense reasonably incurred by Landlord to repair or restore the Premises or the Complex which is not covered by insurance shall be paid by Tenant, in which event such cost and expense shall become Additional Rent payable with the installment of Rent next becoming due under the Terms of this Lease.

11.

INSURANCE

A. Insurance Rating. Except as permitted in Section 2, Tenant will not conduct or permit to be conducted, any activity, or place any equipment, material, chemical, fluid or substance outside of the Premises which will in any way increase the rate of fire insurance or other insurance on the Complex (unless the rate of fire insurance increases only with respect to the Premises and Tenant satisfies such increased premium); if any increase in the rate of fire insurance or other insurance is stated by any insurance company or by the applicable Insurance Rating Bureau to be due to any activity or equipment of Tenant in or about the Premises that is not permitted under this Lease (and the increase in the premium for such policy is not paid by Tenant under its policy), such statement shall be conclusive evidence that the increase in such rate is due to such activity or equipment and as a result thereof, Tenant shall be liable for such increase and shall reimburse Landlord therefor upon demand and any such sum shall be considered Additional Rent payable hereunder.

B. General Requirements. In all insurance policies carried by Tenant pursuant to the requirements of this Lease, Tenant shall name Landlord and Landlord's management agent, if any, as an additional insured, as their interests may appear, and shall contain an endorsement that such policy shall remain in full force and effect notwithstanding that the insured has waived his right of action against any party prior to the occurrence of a loss. Each policy shall contain an endorsement that will prohibit its cancellation prior to the expiration of thirty (30) days after notice of such proposed cancellation to Landlord. All such insurance policies shall be written as primary and non-contributory. Tenant shall provide Landlord with Certificates of Insurance evidencing the coverages required under this Lease prior to the occupancy and at least annually thereafter. Each policy shall be with a company or companies licensed to do business in the State of Texas and approved by Landlord and having a Best Rating of at least "A:VIII". Tenant shall promptly notify Landlord of the cancellation of any insurance required to be carried by Tenant hereunder. If Tenant fails to maintain any insurance required by this Section 11, Landlord may obtain such insurance, and any premium paid by Landlord shall be immediately payable by Tenant to Landlord as Additional Rent. Tenant shall require any permitted sublessee or assignee of the Premises pursuant to this Lease to comply with the requirements of this Section 11.

C. Liability Insurance. Throughout the term, Tenant shall carry commercial general liability insurance, including contractual liability, public liability and property injury, and products and completed operations liability, with limits of at least One Million Dollars ($1,000,000) per occurrence and Two Million Dollars ($2,000,000) aggregate for Tenant’s activities in the Premises, in a form providing occurrence basis coverage, in a form providing occurrence basis coverage.

Each policy shall include a waiver of the insurer's rights of subrogation against the party hereto who is not the insured under said policy.

F. Landlord’s Insurance.

12.

CONDEMNATION

If all or a substantial part of the Premises (or use or occupancy of the Premises) shall be taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including sale under threat of such a taking), then the Term of this Lease shall cease and terminate as of the date when title vests in such governmental or quasi-governmental authority, and the Rent shall be abated on the date when such title vests in such governmental or quasi-governmental authority. If less than a substantial part of the Premises is taken or condemned by any governmental or quasi-governmental authority for any public or quasi-public use or purpose (including sale under threat of such a taking), Tenant may terminate this Lease only if, in its commercially reasonable opinion, its use of the Premises will be materially adversely affected by such taking. If this Lease does not terminate pursuant to the terms of this Section 12, the Rent shall be equitably adjusted (on the basis of the number of square feet of the Premises (and, as applicable, in the Complex) subject to the Lease before and after such event) on the date when title vests in such governmental or quasi-governmental authority and the Lease shall otherwise continue in full force and effect. Tenant shall have no claim against Landlord (or otherwise) and hereby agrees to make no claim against the condemning authority for any portion of the amount that may be awarded as damage as a result of any governmental or quasi-governmental taking or condemnation (or sale under threat of such taking or condemnation) for the value of any expired or unexpired Term of the Lease except for the cost of the portion of the Tenant Improvements made by and paid for by Tenant (it being understood and agreed that the portion of Tenant Improvements paid for by Tenant, for the purpose of allocating condemnation proceeds hereunder, shall not include the portion paid for by Landlord as part of the “Landlord Cap” or that portion of the TI Deferred Payment that has not been repaid to Landlord by Tenant; provided, however, that any recovery by Landlord of condemnation proceeds for Lease Improvements or Tenant Improvements

that were paid for by Landlord as part of the “TI Deferred Payment” shall relieve Tenant from repaying Landlord for such amounts that would have otherwise been due from Tenant to Landlord under Section 7A hereof), together with any payments made by Tenant to Landlord in connection with any modular structures placed on the Premises. Tenant may, if allowed by statute, also seek such awards or damages for moving expenses, loss of profits (provided that, with respect to recovery of loss of profits, that Landlord’s recovery is not diminished thereby) and fixtures and other equipment installed by it which do not, under the Terms of this Lease, become the property of the Landlord at the termination hereof. Such awards or damages must be made by a condemnation court or other authority and must be separate and distinct from award to Landlord and shall not diminish any award of the Landlord. For purposes of this Section 12, a substantial part of the Premises shall be considered to have been taken if more than fifty percent (50%) of the Premises are unusable by Tenant as a direct result of such taking.

13.

SIGNS

Tenant has the right to erect signage on the Music Building and/or landscaped portion of the Common Area within or adjoining the Premises, subject to local ordinance, at Tenant’s sole cost and expense, and in accordance with those commercially reasonable specifications to be established by Landlord regarding signage within the Complex. If allowed by the Historic Design Review Commission, Tenant shall have the right to install a sign facing Houston Street and the plaza, provided that the design of same meets Landlord’s commercial reasonable sign specifications. Landlord shall have the right to prohibit any other advertisement of Tenant which in its reasonable opinion tends to impair the reputation of the Complex or its desirability as a high-quality Complex for offices, and upon written notice from Landlord, Tenant shall immediately refrain from and discontinue any such advertisement.

14.

HAZARDOUS MATERIALS

Tenant shall not cause or knowingly permit any Hazardous Materials (as defined below) to be brought upon, kept or used in or about the Premises or the Complex in violation of Applicable Laws by Tenant or its employees, agents, contractors or invitees (collectively, “Tenant Parties”). Tenant shall indemnify, save, defend (at Landlord's option and with counsel reasonably acceptable to Landlord) and hold the Landlord Indemnified Parties harmless from and against any and all losses, liability, claims, damages, expenses and causes of action ("Claims") that are a direct result of the presence of any Hazardous Materials in, on, under or about the Complex, any portion thereof, or any adjacent property, to the extent caused by Tenant Parties. This indemnification by Tenant includes reasonable costs incurred in connection with any investigation of site conditions or any clean-up, remedial, removal or restoration work required by any governmental or quasi-governmental authority because of the foregoing breach by Tenant which caused Hazardous Materials to be present in the air, soil or groundwater above, on or under or about the Complex in a manner that violates Applicable Laws and which was above levels that were present prior to the Effective Date hereof. Without limiting the foregoing, if the presence of any Hazardous Materials in, on, under or about the Complex, any portion thereof, or any adjacent property, which is caused or knowingly permitted by Tenant results in any contamination of the Complex, any portion thereof or any adjacent property, then Tenant shall promptly take all actions at its sole cost and expense as are reasonably necessary to return the Complex, any portion thereof or any adjacent property to its respective condition existing prior to the time of such contamination (or, if such mitigation is not practicable, then to such level as is in compliance with Applicable Laws); provided that Landlord's written approval of such action shall first be obtained, which approval Landlord shall not unreasonably withhold.

A. Landlord acknowledges that it is not the intent of this Section to prohibit Tenant from operating its business for the use permitted by Section 2. Tenant may operate its business according to the custom of Tenant's industry, which includes the operation of a BSL-2 laboratory, so long as the use or presence of Hazardous Materials is strictly and properly monitored in accordance with Applicable Laws. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, attached Exhibit "E" illustrates the substances the Tenant intends to have in the space during the term of the lease. Tenant agrees (a) this list identifying each type of Hazardous Material is to be present at the Premises that is subject to regulations under any environmental Applicable Laws, and may be updated periodically by Tenant; (b) a list of any and all approvals or permits from governmental or quasi-governmental authorities required in connection with the presence of such Hazardous Material shall be kept at or be made accessible from the Premises, and (c) correct and complete copies of (i) notices of violations of Applicable Laws related to Hazardous Materials and (ii) plans relating to the installation of any storage tanks to be installed in, on, under or about the Complex (provided that installation of storage tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent Landlord may withhold in its sole and absolute discretion) and closure plans or any other documents required by any and all governmental or quasi-governmental authorities for any storage tanks installed in, on, under or above the Complex for the closure of any such storage tanks (collectively, "Hazardous Materials Documents") shall be provided to Landlord by Tenant pursuant to the following sentence. Tenant shall deliver to Landlord updated Hazardous Materials Documents (a) no later than thirty (30) days prior to the initial occupancy of any portion of the Premises or the initial placement of equipment anywhere at the Complex, (b) if there are any changes to the Hazardous Materials Documents, annually thereafter no later than December 31st of each year, and (c) thirty (30) days prior to the initiation by Tenant of any Alterations or changes in Tenant's business that involve any material increase in the types or amounts of Hazardous Materials. For each type of Hazardous Material listed, the Hazardous Materials Documents shall include (i) the chemical names, (ii) the material state (e.g., solid, liquid, gas or cryogen), (ii) the concentration, (iv) the storage amount and storage condition (e.g., in cabinets or not in cabinets), (v) the use amount and use condition (e.g., open use or closed use), (vi) the location (e.g., room number or other identification) and (vii) if known, the chemical abstract service number. Notwithstanding anything in this Section to the contrary, Tenant shall not be required to provide Landlord with any Hazardous Materials Documents containing information of a proprietary nature, which Hazardous Materials Documents, in and of themselves, do not contain a reference to any Hazardous Materials or activities related to Hazardous Materials. Landlord may, at Landlord's expense, cause the Hazardous Materials Documents to be reviewed by a person or firm qualified to analyze Hazardous Materials to confirm compliance with the provisions of this Lease and with Applicable Laws. In the event that a review of the Hazardous Materials Documents indicates non-compliance with this Lease or Applicable Laws, Tenant shall, at its expense, diligently take steps to bring its storage and use of Hazardous Materials into compliance.

B. Notwithstanding the provisions of this Section 14, if (a) Tenant or any proposed transferee, assignee, or sublessee of Tenant has been required by any prior landlord, lender, mortgagee, or governmental or quasi-governmental authority to take material remedial action in connection with Hazardous Materials contaminating a property if the contamination resulted from such party's action or omission or use of the property in question, or (b) Tenant or any proposed transferee, assignee or sublessee is subject to a material enforcement order issued by any governmental or quasi-governmental authority in connection with the use, disposal or storage of Hazardous Materials, then Landlord shall have the right to terminate this Lease in Landlord's sole and absolute discretion (with respect to any such matter involving Tenant), and it shall not be unreasonable for Landlord to withhold its consent to any proposed transfer, assignment, or subletting (with respect to any such matter involving a proposed transferee, assignee or sublessee).

C. At any time, and from time to time, prior to the expiration of the Term, Landlord shall have the right, at Landlord’s sole cost and expense, to conduct appropriate tests of the Complex or any portion thereof, including without limitation the Premises, to investigate whether Hazardous Materials are present or that contamination has occurred due to Tenant or Tenant's employees, agents, contractors or invitees. Notwithstanding the preceding sentence to the contrary, Tenant shall pay all reasonable cost of such test if such test reveals that Hazardous Materials exists at the Complex in violation of this Lease.

D. During the Term, Tenant shall promptly report to Landlord any actual or suspected presence of mold or water intrusion at the Premises of which Tenant obtains actual knowledge.

E. Tenant's indemnification obligations under this Section shall survive the expiration or earlier termination of the lease. During any period of time needed by Tenant or Landlord after the termination of this Lease to complete the removal from the Premises of any such Hazardous Materials, Tenant shall be deemed a holdover tenant and subject to the provisions of Section 17 below.

F. As used herein, the term "Hazardous Material" means any hazardous or toxic substance, material or waste that is or becomes regulated by any governmental or quasi-governmental authority.

15.

SURRENDER

A. At least ten (10) days prior to Tenant's surrender of possession of any part of the Premises, Tenant shall provide Landlord with (a) a facility decommissioning and Hazardous Materials closure plan for the Premises ("Exit Survey") prepared by an independent third party reasonably acceptable to Landlord, (b) written evidence of all appropriate governmental releases obtained by Tenant in accordance with Applicable Laws, including laws pertaining to the surrender of the Premises, and (c) proof that the Premises have been decommissioned in accordance with American National Standards Institute ("ANSI" Publication Z9.11-2008 (entitled "Laboratory Decommissioning") or any successor standard published by ANSI or any successor organization (or, if ANSI and it successors no longer exit, a similar entity publishing similar standards). In addition, Tenant agrees to remain responsible after the surrender of the Premises for the remediation of any recognized environmental conditions (including without limitation, Hazardous Materials) set forth in the Exit Survey. Tenant's obligations under this Section shall survive the expiration or earlier termination of the Lease.

B. No surrender of possession of any part of the Premises shall release Tenant from any of its obligations hereunder, unless such surrender is accepted in writing by Landlord.

C. The voluntary or other surrender of this Lease by Tenant shall not effect a merger with Landlord's fee title or leasehold interest in the Premises or the Complex, unless Landlord consents in writing, which shall not be unreasonably withheld, delayed, denied, or conditioned, and shall, at Landlord's option, operate as an assignment to Landlord of any or all subleases. The voluntary or other surrender of any ground or other underlying lease that now exists or may hereafter be executed affecting the Complex, or a mutual cancellation thereof or of Landlord's interest therein by Landlord and its lessor shall not effect a merger with Landlord's fee title or leasehold interest in the Premises or the Complex.

16.

DEFAULT OF TENANT

A. Events of Default. If Tenant shall (i) fail to pay any monthly installment of Rent (as required by Section 4 or any other provision of this Lease) as and when due or shall fail to timely make any other payment required by the terms and provisions hereof and such failure shall continue for a period of ten (10) days after Tenant receives written notice thereof from Landlord (provided that Landlord shall not be required to provide written notice thereof more than twice in any rolling 12-month period) or, if Landlord is not required to give such notice because it has already done so in a particular rolling 12-month period, and such failure continues for a period of ten (10) days after the due date thereof; (ii) violate or fail to perform any of the other terms, conditions, covenants or agreements herein made by Tenant (or in the Work Letter) and such other violation or failure shall continue for a period of ten (10) days after written notice thereof to Tenant by Landlord (or if such obligation is not reasonably capable of being performed within such 10-day period, if Tenant fails to commence the cure thereof and diligently pursue such cure); (iii) intentionally deleted; or (iv) make or consent to an assignment for the benefit of creditors or a common law composition of creditors, or a receiver of Tenant's assets is appointed, or Tenant files a voluntary petition in any bankruptcy or insolvency proceeding, or an involuntary petition in any bankruptcy or insolvency proceeding is filed against Tenant and not discharged by Tenant within one hundred twenty (120) days, or Tenant is adjudicated a bankrupt, then in any of the foregoing events (each, an "Event of Default"), Landlord shall be entitled to elect from the following remedies:

Landlord may terminate this Lease by giving Tenant written notice thereof, in which event this Lease and the leasehold estate hereby created and all interest of Tenant and all parties claiming by, through or under Tenant shall automatically terminate upon the effective date of such notice. If Landlord elects to so terminate this Lease, everything contained in this Lease on the part of Landlord to be done and performed shall cease without prejudice, however, to the right of Landlord to recover from Tenant all Rent and any other sums accrued up to the time of termination or the date on which Tenant actually vacates the Premises, whichever is later.

Should Landlord terminate this Lease due to an Event of Default, Landlord may elect, as its sole remedy: (i) to accelerate the Basic Rent due hereunder to the end of the Term hereof, discounted to present value at a per annum rate equal to eight percent (8%), minus the then-present fair rental value of the Premises for such period, similarly discounted; (ii) to recover possession of the Premises, by force, summary proceedings, or otherwise or (iii) to relet the Premises for such Rent and upon such terms as are not unreasonable under the circumstances and, Tenant shall be liable for all direct, out of pocket damages sustained by Landlord, including, without limitation, deficiency (if any) in Basic Rent between what Tenant was obligated to pay as Basic Rent under this Lease and the basic rent actually collected by Landlord, reasonable attorneys' fees incurred by Landlord against Tenant, brokerage fees, and expenses of removing Alterations that were not approved by Landlord and reasonable expenses of placing the Premises in rentable condition that comparable with that which existed on the Effective Date.

ii.

Landlord may terminate Tenant’s right to possession of the Premises and enjoyment of the rent, issues and profits therefrom without terminating this Lease or the leasehold estate created hereby, re-enter and take possession of the Premises and remove all persons and property therefrom with or without process of law, without being deemed guilty of any manner of trespass and without prejudice to any remedies for arrears of Rent or existing breaches hereof, and lease, manage and operate the Premises and collect the rents, issues and profits therefrom all for the account of Tenant, and credit to the satisfaction of Tenant’s obligations hereunder the net rental thus received (after deducting therefrom all reasonable costs and expenses of repossessing, leasing, managing and operating the Premises). Tenant shall continue to remain liable to Landlord for all obligations under this Lease, including without limitation, the Rent (subject to any offset for reletting). If the net rental so received by Landlord exceeds the amounts necessary to satisfy all of Tenant’s obligations under this Lease, nevertheless Landlord shall retain such excess. If Landlord elects to proceed under this Section, it may at any time thereafter elect to terminate this Lease as provided in Section 16Ai. Any damage or loss of Rent sustained by Landlord may be recovered by Landlord at the time of an Event of Default, or at Landlord's option, at the time of the reletting, or in separate actions, from time to time, as said damage shall have been made more easily ascertainable by successive relettings, or, at Landlord's option, may be deferred until the expiration of the Term of this Lease, in which event Tenant hereby agrees that the cause of action shall not be deemed to have occurred until the date of expiration of said Term. Landlord shall use commercially reasonable efforts to mitigate its damages resulting from an Event of Default. However, provided that Landlord uses commercially reasonable efforts to relet the Premises, in no event shall Landlord be liable for failure to so lease, manage or operate the Premises or collect the rentals due under any subleases and any such failure shall not reduce Tenant’s liability hereunder.

B. Waiver. If, under the provisions hereof, Landlord shall institute proceedings against Tenant and a compromise or settlement thereof shall be made, the same shall not constitute a waiver of any other covenant, condition or agreement herein contained, nor of any of Landlord's rights hereunder, except to the extent covered by such settlement. No waiver by Landlord of any breach of any covenant, condition or agreement herein contained shall operate as a waiver of such covenant, condition or agreement itself, or of any subsequent breach thereof. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly installment of Rent herein stipulated shall be deemed to be other than on account of the earliest stipulated Rent, nor shall any endorsement or statement on any check or letter accompanying a check for payment of Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such Rent or to pursue any other remedy provided in this Lease. No re-entry by Landlord, and no acceptance by Landlord of keys from Tenant, shall be considered an acceptance or a surrender of the Lease.

C. Right of Landlord to Cure Tenant's Default. Upon the occurrence of an Event of Default, Landlord may, but shall not be required to, make such payment or do such act, and charge the amount of the expense thereof, if made or done by Landlord, with interest thereon at the rate of five percent (5%) per annum from the date paid by Landlord to the date of payment thereof by Tenant; provided, however, that nothing herein contained shall be construed or implemented in such a manner as to allow Landlord to charge or receive interest in excess of the maximum legal rate then allowed by law. Such payment and interest shall constitute Additional Rent hereunder due and payable with the next monthly installment of Rent; but the making of such payment or the taking of such action by Landlord shall not operate to cure such Event of Default or to estop Landlord from the pursuit of any remedy to which Landlord would otherwise be entitled unless and until Tenant so performs such obligation.

D. Tenant Remedies Upon Landlord’s Default. If Landlord fails to perform any of its obligations under this Lease, and such failure continues for a period of thirty (30) days after written notice thereof to Landlord by Tenant (or if such obligation, but only if non-monetary in nature, is not reasonably capable of being performed within such 30-day period, if Landlord fails to commence the cure thereof and diligently pursue such cure), Tenant may, in its sole discretion, as its sole and exclusive remedy, either: (1) cure such failure and receive a credit toward future Rent for the cost incurred by Tenant to cure such failure; or (2) terminate this Lease, upon which termination neither Landlord nor Tenant will have any further obligations of any kind to each other under this Lease.

17.

HOLDOVER

In the event that Tenant does not immediately surrender the Premises on the date of expiration of the Term hereof, Tenant shall, by virtue of the provisions hereof, become a month to month tenant at one hundred fifty percent (150%) the monthly Rent (including all Additional Rent) in effect during the last month of the Term of this Lease, which said monthly tenancy shall commence with the first day next after the expiration of the Term of this Lease. Tenant, a month to month tenant, shall be subject to all of the terms, conditions, covenants and agreements of this Lease. Tenant shall give to Landlord at least thirty (30) days written notice of any intention to quit the Premises, and Tenant shall be entitled to thirty (30) days written notice to quit the Premises, unless and Event of Default has occurred and is continuing, in which event Tenant shall not be entitled to any notice to quit, the usual thirty (30) days' notice to quit being hereby expressly waived.

19.

ASSIGNMENT AND SUBLETTING

A. Landlord's Consent Requirement. Tenant will not assign, transfer, mortgage, or otherwise encumber this Lease or sublet or rent the Premises (or permit the occupancy or use thereof by a person other than Tenant, its employees, licensees, invitees, or affiliates), or any part thereof, without obtaining the prior written consent of Landlord, which shall not be unreasonably withheld, denied, delayed, or conditioned. Tenant shall give Landlord written notice of Tenant's desire to assign, or sublet the Premises. Within thirty (30) days following such request, Landlord shall either consent to such request on such terms and conditions as Landlord may reasonably require or provide written comments regarding its rejection of same. If Tenant requests Landlord's consent to an assignment or sublet of all or any portion of the Premises, Tenant shall reimburse Landlord for reasonable legal fees and expenses, and costs incurred in connection with the preparation and review of the documents to effectuate the assignment or sublet (and Tenant shall be responsible for such legal fees and expenses even if Landlord rejects such proposed assignment or sublet, if such rejection is in accordance with the terms of this Lease). The consent by Landlord to any assignment or subletting shall not be construed as a waiver or release of Tenant from the terms of any covenant or obligation under this Lease, nor shall the collection or acceptance of rent from any such assignee, subtenant or occupant constitute a waiver or release of Tenant of any covenant or obligation contained in this Lease, nor shall any such assignment or subletting be construed to relieve Tenant from obtaining the consent in writing of Landlord to any further assignment or subletting. If an Event of Default has occurred and is continuing, Tenant hereby assigns to Landlord the rent due from any subtenant of Tenant and hereby authorizes each such subtenant to pay said rent directly to Landlord.

If the rent agreed upon between Tenant and its proposed subtenant under any permitted subletting (other than to a Tenant Affiliate) is greater than the sum of the Basic Rent then payable by Tenant under this Lease for the portion of the Premises that is subject to such permitted subletting, then the excess shall be paid to Landlord as Additional Rent when received by Tenant in the same manner that Tenant pays Basic Rent under this Lease. In addition, any lump sum payment to Tenant in connection with any permitted assignment or subletting (other than to a Tenant Affiliate) shall be paid by Tenant to Landlord as Additional Rent.

B. Intra-Tenant Transfer. Notwithstanding the provision of Section 19.A, above, Tenant may assign this Lease or sublet the Premises or any portion thereof, with Landlord's reasonable consent, to any limited liability company, partnership, corporation or entity owned or controlled by Tenant or owned or controlled by any entity owning one hundred percent (100%) of ownership interests in Tenant (a "Tenant Affiliate"), provided that (i) the Tenant Affiliate has the same or better financial position as the Tenant on the Lease Commencement Date; (ii) there is no change in the permitted use of the Premises; and (iii) Tenant remains fully liable for the obligations of the Tenant under this Lease and that regardless of Tenant remaining liable under the Lease in the event of an assignment, such entity assumes jointly and severally the obligations of Tenant hereunder. Tenant shall immediately notify Landlord of any such assignment or subletting under the terms of this Section 19.B. Unless permitted under the terms of this Section 19.B., any sale of ownership interests in Tenant shall be deemed a transfer of this Lease subject to the terms of Section 19.A. above.

20.

QUIET ENJOYMENT

Landlord covenants that it has the right to make this Lease for the Term aforesaid, and that if Tenant shall pay the Rent and perform all of the covenants, terms, conditions and agreements of this Lease to be performed by Tenant, Tenant shall, during the Term hereby created, freely, peaceably and quietly occupy and enjoy the full possession of the Premises without molestation, disturbance, or hindrance by Landlord or any party claiming through or under Landlord, subject to the provisions of this Lease.

SUBORDINATION

Subject to the delivery of an SNDA (as hereinafter defined), this Lease is subject and subordinate to all ground or underlying leases and to all mortgages and/or deeds of trust which may now or hereafter affect such leases or the real property of which the Premises form a part, and to all renewals, modifications, consolidations, replacements and extensions thereof. In confirmation of such subordination, Tenant shall execute promptly any certificate that the Landlord, or the holder of such deed of trust, may reasonably request, provided that such certificate contains commercially reasonable non-disturbance and attornment provisions. Notwithstanding the foregoing, in the event of any foreclosure sale under such deed of trust, this Lease shall continue in full force and effect, and the Tenant hereby attorns to the party secured by such deed of trust or the purchaser under any such foreclosure sale, which attornment is self-operative and requires no further instrument or agreement. Tenant covenants and agrees that, notwithstanding the self-operative nature of the attornment contained herein, Tenant will, at the written request of the party secured by any such deed of trust, execute, acknowledge and deliver any commercially reasonable instrument that has for its purpose and effect the confirmation of the subordination, non-disturbance, and attornment provisions contained herein (the "SNDA").

22.

RULES AND REGULATIONS

Tenant, its agents, employees, invitees, licensees, customers, clients, family members and guests shall at all times abide by and observe the rules and regulations attached hereto as Exhibit "D".

Landlord agrees to use commercially reasonable efforts to enforce the rules and regulations of the complex fairly. If there is any inconsistency between this Lease and the rules and regulations as set forth in Exhibit "D", as may be updated from time to time, this Lease shall govern. The Landlord may, upon request by any tenant, waive the compliance by such Tenant of any of the rules and regulations provided that (i) no waiver shall be effective unless signed by Landlord or Landlord's authorized agent, (ii) any such waiver shall not relieve such Tenant from the obligation to comply with such rule or regulation in the future unless expressly consented to by Landlord, and (iii) no waiver granted to any tenant shall relieve any other tenant from the obligation of complying with the following rules and regulations unless such other tenant has received a similar waiver in writing from Landlord.

23.

Such efforts may include admission of an HTC investor as a member of Landlord or lease (the “Master Lease”) of the Premises by Landlord to an entity (the “Master Tenant”) jointly owned by an affiliate of Landlord and an HTC investor. In the event of a Master Lease of the Premises, Landlord shall assign its rights under this Lease to the Master Tenant and Tenant shall consent to any such assignment.

BASIC WORK LETTER INFORMATION

Tenant’s Representative: Xxxx Xxxxxxxxx

Landlord’s Representative: XX Xxxxx

Architect: Xxxxxxx Architects

This Work Letter shall set forth the terms and conditions relating to the construction of the Premises. This Work Letter is essentially organized chronologically and addresses the issues of the construction of the Premises, in sequence, as such issues will arise during the actual construction of the Premises. All references in this Work Letter to Sections of the "Lease" shall mean the relevant portions of the Lease to which this Work Letter is attached as Exhibit C, and all references in this Work Letter to Sections of "this Work Letter" shall mean the relevant portions of this Work Letter. All capitalized terms in this Work Letter that are not defined in this Work Letter shall have the meanings given them in the Lease.

SECTION 1

LANDLORD'S INITIAL CONSTRUCTION IN THE PREMISES

1.1

Landlord is constructing all of the improvements necessary for Tenant’s use of the Premises, as more fully set forth in the standards described or referenced on Schedule 1.1 to this Work Letter. Out of the improvements, the base, shell, and core of the Premises shall be completed by Landlord at Landlord’s sole expense and shall be referred to as the “Lease Improvements”. All other improvements necessary for Tenant’s use shall be referred to as the Tenant Improvements and shall be at the sole expense of Tenant, save and except the Landlord Cap. Landlord agrees not to amend the Lease Improvements Construction Contract without Tenant’s prior written consent, which shall not be unreasonably withheld, delayed, denied, or conditioned. Notwithstanding the previous sentence, Landlord may make such changes to the Lease Improvements as required by applicable governmental authorities, along with non-material “field” changes to the Lease Improvements, provided Landlord provides written notice to Tenant of such changes.

SECTION 2

TENANT IMPROVEMENTS

2.1 Landlord approves the plans for Tenant’s improvements (the “Tenant Improvements”) within the Premises, described or referenced on Schedules 1.1 and 2.1, which Landlord shall construct or cause to be constructed in the Premises after the Lease Improvements are complete or in conjunction with the Lease Improvements, subject to the terms of the Lease (including Section 7.A). Tenant agrees not to amend the Plans and Specifications (as hereinafter defined) without Tenant’s prior written consent, which shall not be unreasonably withheld, delayed, denied, or conditioned. Notwithstanding the previous sentence, Tenant may make such changes to the Plans and Specifications as required by applicable governmental authorities, along with non-material “field” changes to the Plans and Specifications, provided Tenant provides written notice to Landlord of such changes.

SECTION 3

CONSTRUCTION OF THE LEASE IMPROVEMENTS

3.1

Contractors. One or more contractors retained by Landlord (the "Contractors") shall construct the Lease Improvements and Tenant Improvements.

3.2

Contractors' Warranties and Guaranties. As a condition of Substantial Completion, Landlord shall assign to Tenant, at Landlord’s cost, all warranties and guaranties by the Contractors relating to the Lease Improvements, Tenant Improvements and relating to the FF&E, and provide evidence of each Contractors’ or warrantor’s consent to same (including, without limitation, that certain warranty of Landlord’s General Contractor, covering the Lease Improvements and Tenant Improvements) pursuant to the Lease Improvements Construction Contract (collectively, the “Warranties”). Landlord shall cooperate reasonably with Tenant in requesting performance of the applicable contractor’s obligations under the Warranties and in enforcing Tenant’s rights thereunder.

SECTION 4

COMPLETION OF THE LEASE IMPROVEMENTS: LEASE COMMENCEMENT DATE

4.1 Substantial Completion. For purposes of this Lease, "Substantial Completion" of the Lease Improvements and Tenant Improvements shall occur upon: (a) completion of construction of the Lease Improvements and Tenant Improvements in the Premises, as certified in writing by the Architect (with such certification delivered to Landlord and Tenant), with the exception of any punch-list items (together with Landlord’s agreement for the timing of completion of such punch-list items) and any Tenant fixtures, workstations, built-in furniture, or equipment to be installed by Tenant or under the supervision of the Contractors, all as verified by Tenant and Tenant’s project management consultant, which verification shall occur as soon as reasonably practicable in a commercially reasonable manner following Tenant’s receipt of written notice from Landlord that the Premises are ready for a final walk-through in order to confirm completion and the content of the punch-list; (b) Landlord’s assignment of warranties and guaranties described in Section 3.2 of this Work Letter and delivery of same to Tenant; and (c) evidence that the costs of the Leasehold Improvements have been paid.

4.2 Delay of Substantial Completion of the Premises. Except as provided in this Section 4, the Lease Commencement Date shall occur as set forth in the Lease. If there shall be a delay or there are delays in the Substantial Completion of the Premises (based upon the anticipated date of the occurrence of the Lease Commencement Date as set forth in the Lease) or in the occurrence of any of the other conditions precedent to the Lease Commencement Date, as set forth in the Lease, as a direct, result of any of the following (collectively, "Tenant Delays"):

4.2.1

Tenant's failure to timely approve any matter requiring Tenant's approval, provided that Landlord has requested such approval from Tenant’s Representative in writing;

4.2.2

A breach by Tenant of the terms of this Work Letter or this Lease;

4.2.3

Tenant' s requirement for materials, components, finishes, or improvements that are not available in a reasonable time (based upon the anticipated date of the Lease Commencement Date), provided that Landlord has so notified Tenant and provided Tenant with an opportunity to modify Tenant’s requirements;

then, notwithstanding anything to the contrary set forth in this Lease and regardless of the actual date of the Substantial Completion of the Premises, the date of Substantial Completion (for purposes of determining the Lease Commencement Date) shall be deemed to be the date on which Substantial Completion of the Premises would have occurred if no Tenant Delays, as set forth above, had occurred.

SECTION 5

MISCELLANEOUS

5.1 Tenant' s Entry into the Premises Prior to Substantial Completion. Provided that Tenant and its agents do not interfere with, or delay, the Contractors' work in the Complex and the Premises, the Contractors shall allow Tenant access to the Premises prior to the Substantial Completion of the Premises for the purpose of Tenant installing Tenant's data and telephone equipment and cabling in the Premises. The installation of the telephone and data cabling will be coordinated with the Contractors to cause such work to be performed at a time reasonably designated by the Contractors. Prior to Tenant's entry into the Premises as permitted by the terms of this Section 5.1, Tenant shall submit a schedule to Landlord and the Contractors, for their approval, which schedule shall detail the timing and purpose of Tenant's entry. Tenant shall hold Landlord harmless from and indemnify, protect, and defend Landlord against any loss or damage to the Building or Premises and against injury to any persons caused by Tenant's actions pursuant to this Section 5.1.

5.2 Tenant's Representative. Tenant has designated Tenant's Representative, as set forth above, as its sole representative with respect to the matters set forth in this Work Letter, who shall have full authority and responsibility to act on behalf of Tenant as required in this Work Letter.

5.3 Landlord's Representative. Landlord has designated Landlord's Representative, as set forth above, as its sole representative with respect to the matters set forth in this Work Letter, who, until further notice to Tenant, shall have full authority and responsibility to act on behalf of Landlord as required in this Work Letter.

5.4 Time of the Essence in This Work Letter. Unless otherwise indicated, all references herein to a "number of days" shall mean and refer to calendar days. In all instances where Tenant is required to approve or deliver an item, if no written notice of approval is given or the item is not delivered within the stated time period, at Landlord's sole option, at the end of said period the item shall automatically be deemed approved or delivered by Tenant and the next succeeding time period shall commence.

5.5 Tenant's Lease Default. Notwithstanding any provision to the contrary contained in this Lease, if an Event of Default (as defined in Section 16A of the Lease) at any time on or before the Substantial Completion of the Premises, then (i) in addition to all other rights and remedies granted to Landlord pursuant to this Lease, Landlord may cause the Contractors to cease the construction of the Lease Improvements and Tenant Improvements (in which case Tenant shall be responsible for any delay in the Substantial Completion of the Premises caused by such work stoppage as set forth in Section 4.2 of this Work Letter), and all other obligations of Landlord under the terms of this Work Letter shall be suspended until such time as such Event of Default is cured pursuant to the terms of this Lease.

Schedule 1.1 to Work Letter

The Lease Improvements and the Tenant Improvements shall be the work referenced in that certain AIA Document A102-2017, Standard Form of Agreement Between Owner and Contractor between Texas Research and Technology Foundation on behalf of Owner and Metropolitan Contracting Company, LLC dated August 17, 2020 and as further described the Bid and Permitting Plans and Specifications and Addendum 1 dated June 29, 2020, along with the addendum, amendments, additional work, and change orders listed in the 20037 TRTF Music PCO Log dated August 31, 2020 attached hereto as Schedule 2.1 (collectively, the “Plans and Specifications”). The parties agree that the percentage of each line item on Schedule 2.1 that is considered “Tenant Improvements” and therefore subject to the Landlord Cap consist of those line items for which a percentage is listed in the column denoted “Finish-Out %” in Schedule 2.1. The “Lease Improvements” consist of those line items for which “0%” is listed and the remainder of the percentage not assigned to Tenant as “Finish-Out %”. By way of example, the line item marked PCO # 044 is listed as 70% in the Finish-Out % column. Therefore, PCO #044 shall consist of 70% Tenant Improvements and 30% Lease Improvements. The parties stipulate and agree to the percentages shown in Schedule 2.1.
