Landlord shall approve or disapprove any requested transfer within thirty (30) days following delivery of Tenant's written request, the information set forth above, and the fee set forth below.

Tenant agrees that the subtenant may rely on that notice without any duty of further inquiry and notwithstanding any notice or claim by Tenant to the contrary. Tenant shall have no right or claim against the subtenant or Landlord for any rentals so paid to Landlord.

(c) In the event of the termination of this Lease for any reason, including without limitation as the result of an Event of Default by Tenant or by the mutual agreement of Landlord and Tenant, Landlord may, at its sole option, take over Tenant's entire interest in any sublease and, upon notice from Landlord, the subtenant shall attorn to Landlord. ln no event, however, shall Landlord be liable for any previous act or omission by Tenant under the sublease or for the return of any advance rental payments or deposits under the sublease that have not been actually delivered to Landlord, nor shall Landlord be bound by any sublease modification executed without Landlord's consent or for any advance rental payment by the subtenant in excess of one month's rent. The provisions of this Lease (other than with respect to the payment of rent), including without limitation those pertaining to insurance and indemnification, shall be deemed incorporated by reference into the sublease despite the termination of this Lease. In the event Landlord does not elect to take over Tenant's interest in a sublease in the event of any such termination of this Lease, such sublease shall terminate concurrently with the termination of this Lease and such subtenant shall have no further rights under such sublease and Landlord shall have no obligations to such subtenant.

SECTION 10.4. LANDLORD'S NONLIABILITY. Landlord, its agents, and any and all affiliates of Landlord, shall not be liable to Tenant, its employees, agents and/or invitees, and Tenant hereby waives all claims against Landlord, its agents, and any and all affiliates of Landlord, for and knowingly assumes the risk of loss of or damage to any property, or loss or interruption of business or income, or any other loss, cost, damage, injury or liability whatsoever (including without limitation any consequential damages and lost profit or opportunity costs), resulting from, but not limited to, Acts of God, acts of civil disobedience or insurrection, acts or omissions of third parties and/or of other tenants of the Premises or their agents, employees, contractors, guests or invitees, fire, explosion, falling plaster, steam, gas, electricity, water or rain which may leak or flow from or into any part of the Premises, mold, or from the breakage, leakage, obstruction or other defects of the pipes, sprinklers, wires, appliances, plumbing, air conditioning, electrical works, roof, windows or other fixtures in the Building (whether the damage or injury results from conditions arising in the Premises or in other portions of the Building), regardless of the negligence of Landlord, its agents or any and all affiliates of Landlord in connection with any of the foregoing. It is understood that any such condition may require the temporary evacuation or closure of all or a portion of the Building. Landlord shall have no liability whatsoever (including without limitation consequential damages and lost profit or opportunity costs) and, except as provided in Sections 11.1 and 12.1 below, there shall be no abatement of rent, by reason of any injury to or interference with Tenant's business arising from the making of any repairs, alterations or improvements to any portion of the Building, including repairs to the Premises, nor shall any related activity by Landlord constitute an actual or constructive eviction. In making repairs, alterations or improvements, however, Landlord shall interfere as little as reasonably practicable with the conduct of Tenant's business in the Premises. Should Tenant elect to receive any service or products from a concessionaire, licensee or third party tenant of Landlord, Landlord shall have no liability for any services or products so provided or for any breach of contract by such third party provider. Neither Landlord nor its agents shall be liable for interference with light or other similar intangible interests. Tenant shall immediately notify Landlord in case of fire or accident in the Premises or the Building and of defects in any improvements or equipment.

SECTION 10.5. WAIVER OF SUBROGATION. Landlord and Tenant each hereby waives all rights of recovery against the other and the other's agents on account of loss and damage occasioned to the property of such waiving party to the extent that the waiving party is entitled to proceeds for such loss or damage under any property insurance policies carried or required to be carried by the provisions of this Lease; provided however, that the foregoing waiver shall not apply to the extent of Tenant's obligations to pay deductibles under any such policies and this Lease. By this waiver it is the intent of the parties that neither Landlord nor Tenant shall be liable to any insurance company (by way of subrogation or otherwise) insuring the other party for any loss or damage insured against under any property insurance policies contemplated by this Lease, even though such loss or damage might be occasioned by the negligence of such party, its agents, employees, contractors, guests or invitees.

ARTICLE XI. DAMAGE OR DESTRUCTION

SECTION 11.1. RESTORATION.

(a) If the Premises or the Building or a part thereof are materially damaged by any fire, flood, earthquake or other casualty, Landlord shall have the right to terminate this Lease upon written notice to Tenant if: (i) Landlord reasonably determines that proceeds necessary to pay the full cost of repair are not available from Landlord's insurance, including without limitation earthquake insurance, plus such additional amounts Tenant elects, at its option, to contribute, excluding however the deductible (for which Tenant shall be responsible for Tenant's Share); (ii) Landlord reasonably determines that the Premises cannot, with reasonable diligence, be fully repaired by Landlord (or cannot be safely repaired because of the presence of hazardous factors, including without limitation Hazardous Materials, earthquake faults, and other similar dangers) within two hundred seventy (270) days after the date of the damage; (iii) an Event of Default by Tenant has occurred; or (iv) the material damage occurs during the final twelve (12) months of the Term. Landlord shall notify Tenant in writing ("Landlord's Notice") within sixty (60) days after the damage occurs as to (A) whether Landlord is terminating this Lease as a result of such material damage and (B) if Landlord is not terminating this Lease, the number of days within which Landlord estimates that the Premises, with reasonable diligence, are likely to be fully repaired. In the event Landlord elects to terminate this Lease, this Lease shall terminate as of the date specified for termination by Landlord’s Notice (which termination date shall in no event be later than sixty (60) days following the date of the damage, or, if no such date is specified, such termination shall be the date of Landlord's Notice).

ThermoGenesis Holdings Inc. Lease

(b) If Landlord has the right to terminate this Lease pursuant to Section 11.l(a) and does not elect to so terminate this Lease, and provided that at the time of Landlord's Notice neither an Event of Default exists nor has Landlord delivered to Tenant a notice of any failure by Tenant to fulfill an obligation under this Lease which, unless cured by Tenant within the applicable grace period, would constitute an Event of Default, then within ten (10) days following delivery of Landlord's Notice pursuant to Section 11.1(a), Tenant may elect to terminate this Lease by written notice to Landlord, but only if (i) Landlord's Notice specifies that Landlord has determined that the Premises cannot be repaired, with reasonable diligence, within two hundred seventy (270) days after the date of damage or (ii) the casualty has occurred within the final twelve (12) months of the Term and such material damage has a materially adverse impact on Tenant's continued use of the Premises. If Tenant fails to provide such termination notice within such ten (10) day period, Tenant shall be deemed to have waived any termination right under this Section 11.1(b) or any other applicable law.

(c) In the event that neither Landlord nor Tenant terminates this Lease pursuant to this Section 11.1 as a result of material damage to the Building or Premises resulting from a casualty, Landlord shall repair all material damage to the Premises or the Building as soon as reasonably possible and this Lease shall continue in effect for the remainder of the Term. Subject to any provision to the contrary in the Work Letter, such repair by Landlord shall include repair of material damage to the Tenant Requested Improvements constructed pursuant to the Work Letter. Landlord's repair of material damage shall be at Landlord's sole cost and expense except for any insurance deductible (for which Tenant shall be responsible for Tenant's Share). Landlord shall have the right, but not the obligation, to repair or replace any other leasehold improvements made by Tenant or any Alterations (as defined in Section 7.3) constructed by Tenant as part of Landlord's repair of material damage, in which case Tenant shall make available to Landlord upon demand insurance proceeds from insurance required to be maintained by Tenant. If Landlord elects to repair or replace such leasehold improvements and/or Alterations, all insurance proceeds available for such repair or replacement shall be made available to Landlord. Landlord shall have no liability to Tenant in the event that the Premises or the Building has not been fully repaired within the time period specified by Landlord in Landlord's Notice to Tenant as described in Section 11.1(a). Notwithstanding the provisions of this Article Xl, the repair of damage to the Premises to the extent such damage is not material shall be governed by Sections 7.1 and 7.2.

(d) Commencing on the date of such material damage to the Building, and ending on the sooner of the date the damage is repaired or the date this Lease is terminated, the rental to be paid under this Lease shall be abated in the same proportion that the Floor Area of the Premises that is rendered unusable by the damage from time to time bears to the total Floor Area of the Premises, as determined by Landlord, but only to the extent that Landlord is entitled to reimbursement from the proceeds of the business interruption insurance required to be maintained by Tenant pursuant to Exhibit D.

(e) Landlord shall not be required to repair or replace any improvements or fixtures that Tenant is obligated to repair or replace pursuant to Section 7.1 or any other provision of this Lease and Tenant shall continue to be obligated to so repair or replace any such improvements or fixtures, notwithstanding any provisions to the contrary in this Article XI. In addition, but subject to the provisions of Section 10.5, in the event the damage or destruction to the Premises or Building are due in substantial part to the fault or neglect of Tenant or its employees, subtenants, invitees or representatives, the costs of such repairs or replacement to the Premises or Building shall be borne by Tenant, and in addition, Tenant shall not be entitled to terminate this Lease as a result, notwithstanding the provisions of Section 11.1(b).

(f) Tenant shall fully cooperate with Landlord in removing Tenant's personal property and any debris from the Premises to facilitate all inspections of the Premises and the making of any repairs. Notwithstanding anything to the contrary contained in this Lease, if Landlord in good faith believes there is a risk of injury to persons or damage to property from entry into the Building or Premises following any damage or destruction thereto, Landlord may restrict entry into the Building or the Premises by Tenant, its employees, agents and contractors in a non-discriminatory manner, without being deemed to have violated Tenant's rights of quiet enjoyment to, or made an unlawful detainer of, or evicted Tenant from, the Premises. Upon request, Landlord shall consult with Tenant to determine if there are safe methods of entry into the Building or the Premises solely in order to allow Tenant to retrieve files, data in computers, and necessary inventory, subject however to all indemnities and waivers of liability from Tenant to Landlord contained in this Lease and any additional indemnities and waivers of liability which Landlord may require.

ThermoGenesis Holdings Inc. Lease

SECTION 11.2. LEASE GOVERNS. Tenant agrees that the provisions of this Lease, including without limitation Section 11.1, shall govern any damage or destruction and shall, accordingly, supersede any contrary statute or rule of law.

ARTICLE XII. EMINENT DOMAIN

SECTION 12.1. TOTAL OR PARTIAL TAKING. If all or a material portion of the Premises is taken by any lawful authority by exercise of the right of eminent domain, or sold to prevent a taking, either Tenant or Landlord may terminate this Lease effective as of the date possession is required to be surrendered to the authority. In the event title to a portion of the Building, whether or not including a portion of the Premises, is taken or sold to prevent a taking, and if Landlord elects to restore the Building in such a way as to alter the Premises materially, either party may terminate this Lease, by written notice to the other party, effective on the date of vesting of title. In the event neither party has elected to terminate this Lease as provided above, then Landlord shall promptly, after receipt of a sufficient condemnation award, proceed to restore the Premises to substantially their condition prior to the taking, and a proportionate allowance shall be made to Tenant for the rent corresponding to the time during which, and to the part of the Premises of which, Tenant is deprived on account of the taking and restoration. In the event of a taking, Landlord shall be entitled to the entire amount of the condemnation award without deduction for any estate or interest of Tenant; provided that nothing in this Section shall be deemed to give Landlord any interest in, or prevent Tenant from seeking any award against the taking authority for, the taking of personal property and fixtures belonging to Tenant or for relocation or business interruption expenses recoverable from the taking authority.

SECTION 12.2. TEMPORARY TAKING. No temporary taking of the Premises shall terminate this Lease or give Tenant any right to abatement of rent, and any award specifically attributable to a temporary taking of the Premises shall belong entirely to Tenant. A temporary taking shall be deemed to be a taking of the use or occupancy of the Premises for a period of not to exceed ninety (90) days.

SECTION 12.3. TAKING OF PARKING AREA. In the event there shall be a taking of the parking area such that Landlord can no longer provide sufficient parking to comply with this Lease, Landlord may substitute reasonably equivalent parking in a location reasonably close to the Building; provided that if Landlord fails to make that substitution within ninety (90) days following the taking and if the taking materially impairs Tenant's use and enjoyment of the Premises, Tenant may, at its option, terminate this Lease by written notice to Landlord. If this Lease is not so terminated by Tenant, there shall be no abatement of rent and this Lease shall continue in effect.

ARTICLE XllI. SUBORDINATION; ESTOPPEL CERTIFICATE; FINANCIALS

SECTION 13.1. SUBORDINATION. At the option of Landlord or any lender of Landlord's that obtains a security interest in the Building, this Lease shall be either superior or subordinate to all ground or underlying leases, mortgages and deeds of trust; if any, which may hereafter affect the Building; and to all renewals, modifications, consolidations, replacements and extensions thereof; provided, that so long as no Event of Default exists under this Lease, Tenant's possession and quiet enjoyment of the Premises shall not be disturbed and this Lease shall not terminate in the event of termination of any such ground or underlying lease, or the foreclosure of any such mortgage or deed of trust, to which this Lease has been subordinated pursuant to this Section. Tenant shall execute and deliver any documents or agreements requested by Landlord or such lessor or lender which provide Tenant with the non-disturbance protections set forth in this Section. In the event of a termination or foreclosure, Tenant shall become a tenant of and attorn to the successor-in-interest to Landlord upon the same terms and conditions as are contained in this Lease, and shall execute any instrument reasonably required by Landlord's successor for that purpose. Tenant shall also, upon written request of Landlord, execute and deliver all instruments as may be required from time to time to subordinate the rights of Tenant under this Lease to any ground or underlying lease or to the lien of any mortgage or deed of trust (provided that such instruments include the non-disturbance and attornment provisions set forth above), or, if requested by Landlord, to subordinate, in whole or in part, any ground or underlying !ease or the lien of any mortgage or deed of trust to this Lease. Tenant agrees that any purchaser at a foreclosure sale or lender taking title under a deed-in-lieu of foreclosure shall not be responsible for any act or omission of a prior landlord, shall not be subject to any offsets or defenses Tenant may have against a prior landlord, and shall not be liable for the return of the security deposit to the extent it is not actually received by such purchaser or bound by any rent paid for more than the current month in which the foreclosure occurred.

ThermoGenesis Holdings Inc. Lease

SECTION 13.2. ESTOPPEL CERTIFICATE.

(a) Tenant shall within ten (10) days following written request from Landlord, execute, acknowledge and deliver to Landlord, in any form that Landlord may reasonably require, a statement in writing (i) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of the modification and certifying that this Lease, as modified, is in full force and effect) and the dates to which the rental, additional rent and other charges have been paid in advance, if any, and (ii) acknowledging that, to Tenant's knowledge, there are no uncured defaults on the part of Landlord, or specifying each default if any are claimed, and (iii) setting forth all further information that Landlord or any prospective purchaser or encumbrancer may reasonably require. Tenant's statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the Building.

(b) Notwithstanding any other rights and remedies of Landlord, Tenant's failure to deliver any estoppel statement within the provided time shall be conclusive upon Tenant that (i) this Lease is in full force and effect, without modification except as may be represented by Landlord, (ii) there are no uncured Events of Default in Landlord's performance, and (iii) not more than one month's rental has been paid in advance.

SECTION 13.3. FINANCIALS.

(a) Tenant shall deliver to Landlord, prior to the execution of this Lease and thereafter at any time and from time to time within ten (10) days following Landlord's written request, Tenant's current tax returns and financial state certified to be true, accurate and complete by the chief financial officer of Tenant, including a balance sheet and profit and loss statement for the most recent prior year, (collectively, the “Statements"), which Statements shall accurately and completely reflect the financial condition of Tenant; provided, however, that in the event and so long as Tenant is a publicly traded corporation on a nationally recognized stock exchange, the foregoing obligation-to-deliver the Statements shall be waived. If delivered to Landlord marked or otherwise designated as “confidential,” Landlord agrees that it will keep the Statements confidential except that Landlord shall have the right to deliver the same to any proposed purchaser of the Building, and to any encumbrancer or proposed encumbrancer of all or any portion of the Building.

(b) Tenant acknowledges that Landlord is relying on the Statements in its determination to enter into this Lease, and Tenant represents to Landlord, which representation shall be deemed made on the date of this Lease and again on the Commencement Date, that no material change in the financial condition of Tenant, as reflected in the Statements, has occurred since the date Tenant delivered the Statements to Landlord. The Statements are represented and warranted by Tenant to be correct and to accurately and fully reflect Tenant's true financial condition as of the date of submission of any Statements to Landlord.

ARTICLE XIV. EVENTS OF DEFAULT AND REMEDIES

SECTION 14.1. TENANT'S DEFAULTS. The occurrence of any one or more of the following events (following the expiration of any cure period set forth below, if any is provided) shall constitute an "Event of Default'' by Tenant:

(a) The failure by Tenant to make any payment of Basic Rent or additional rent required to be made by Tenant, as and when due, where the failure continues for a period of five (5) days after written notice from Landlord to Tenant; provided, however, that any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 and 1161(a) as amended. For purposes of these Events of Default and remedies provisions, the term "additional rent” shall be deemed to include all amounts of any type whatsoever other than Basic Rent to be paid by Tenant pursuant to the terms of this Lease and the Work Letter.

ThermoGenesis Holdings Inc. Lease

(b) The assignment, sublease, emcumbrance or other transfer of this Lease by Tenant, either voluntarily or by operation of law, whether by judgment, execution, transfer by intestacy or testacy, or other means, without the prior written consent of Landlord when consent is required by this Lease.

(c) The discovery by Landlord that any financial statement provided by Tenant, or by any affiliate, successor or guarantor of Tenant, was materially false.

(d) The failure of Tenant to timely and fully provide any subordination agreement, estoppel certificate or financial statements in accordance with the requirements of Article XIII.

(e) The abandonment of the Premises by Tenant.

(f) The failure or inability by Tenant to observe or perform any of the express or implied covenants or provisions of xx.xx Lease to be observed or performed by Tenant, other than as specified in this Section 14.1, where the failure continues for a period of thirty (30) days after written notice from Landlord to Tenant or such shorter period as is specified in any other provision of this Lease; provided, however, that any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 and 1161(a) as amended. However, if the nature of the failure is such that more than thirty (30) days are reasonably required for its cure, then an Event of Default shall not be deemed to have occurred if Tenant commences the cure within thirty (30) days, and thereafter diligently pursues the cure to completion.

(g) (i) The making by Tenant of any general assignment for the benefit of creditors; (ii) the filing by or against Tenant of a petition to have Tenant adjudged a Chapter 7 debtor under the Bankruptcy Code, to have debts discharged or for reorganization or arrangement under any law relating to bankruptcy (unless, in the case of a petition filed against Tenant, the same is dismissed within thirty (30) days); (iii) the appointment of a trustee or receiver to take possession of substantially all of Tenant's assets located at the Premises or of Tenant's interest in this Lease, if possession is not restored to Tenant within thirty (30) days; (iv) the attachment. execution or other judicial seizure of substantially all of Tenant's assets located at the Premises or of Tenant's interest in this Lease, where the seizure is not discharged within thirty (30) days; (v) Tenant's convening of a meeting of its creditors for the purpose of effecting a moratorium upon or composition of its debts; or (vi) the failure of Tenant to pay its material obligations to creditors as and when they become due and payable, other th.an as a result of a good faith dispute by Tenant as to the amount due to such creditors. Landlord shall not be deemed to have knowledge of any event described in this Section 14.1(g) unless notification in writing is received by Landlord, nor shall there be any presumption attributable to Landlord of Tenant's insolvency. In the event that any provision of this Section 14.1(g) is contrary to applicable law, the provision shall be of no force or effect.

(h) Any other breach of this Lease which this Lease provides is an Event of Default.

SECTION 14.2. LANDLORD'S REMEDIES.

(a) If an Event of Default by Tenant occurs, then in addition to any other remedies available to Landlord, Landlord may exercise the following remedies:

ThermoGenesis Holdings Inc. Lease

(i) Landlord may terminate Tenant's right to possession of the Premises by any lawful means, in which case this Lease shall terminate and Tenant shall immediately surrender possession of the Premises to Landlord. Such termination shall not affect any accrued obligations of Tenant under this Lease. Upon termination, Landlord shall have the right to reenter the Premises and remove all persons and property. Landlord shall also be entitled to recover from Tenant (and to retain, use or apply any Security Deposit held by Landlord towards amounts estimated by Landlord as):

(1) The worth at the time of award of the unpaid Basic Rent and additional rent which had been earned at the time of termination;

(2) The worth at the time of award of the amount by which the unpaid Basic Rent and additional rent which would have been earned after termination until the time of award exceeds the amount of such loss that Tenant proves could have been reasonably avoided;

(3) The worth at the time of award of the amount by which the unpaid Basic Rent and additional rent for the balance of the Term after the time of award exceeds the amount of which loss that Tenant proves could be reasonably avoided;

(4) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant's failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result from Tenant's Event of Default, including, but not limited to, the cost of recovering possession of the Premises, refurbishment of the Premises, marketing costs, commissions and other expenses of reletting, including necessary repair, the unamortized portion of any tenant improvements and brokerage commissions funded by Landlord in connection with this Lease, reasonable attorneys' fees, and any other reasonable costs; and

(5) At Landlord's election, all other amounts in addition to or in lieu of the foregoing as may be permitted by law. The term "rent" as used in the Lease shall be deemed to mean the Basic Rent, Tenant's Share of Operating Expenses and any other sums required to be paid by Tenant to Landlord pursuant to the terms of this lease whether or not designated as additional rent hereunder, including, without limitation, any sums that may be owing from Tenant pursuant to Section 4.3 of this Lease. Any sum, other than Basic Rent, shall be computed on the basis of the average monthly amount accruing during the twenty-four (24) month period immediately prior to the Event of Default, except that if it becomes necessary to compute such rental before the twenty-four (24) month period has occurred, then the computation shall be on the basis of the average monthly amount during the shorter period. As used in Sections 14.2(a)(i)(1), (2) and (3) above, the “worth at the time of award" shall be computed by allowing interest at the rate of ten percent (10%) per annum.

(6) In the event of a Tenant’s Default or earlier termination of the Lease during the initial 66 month term only, Tenant is responsible to immediately pay back, in full amount, the Landlord Contribution toward the Tenant Requested Improvements as described in Work Letter. The full amount of Landlord Contribution is due ten (10) days from the time a Tenant‘s Default or earlier termination occurs.

(ii) Landlord may elect not to terminate Tenant's right to possession of the Premises and to continue to enforce all of its rights and remedies under this Lease, including the right to collect all rent as it becomes due as provided in Civil Code Section 1951.4. Efforts by the Landlord to maintain, preserve or relet the Premises, or the appointment of a receiver to protect the Landlord's interests under this Lease, shall not constitute a termination of the Tenant's right to possession of the Premises. ln the event that Landlord elects to avail itself of the remedy provided by this Section 14.2(a)(ii), Landlord shall not unreasonably withhold its consent to an assignment or subletting of the Premises subject to the reasonable standards for Landlord's consent as are contained in this Lease.

(b) Landlord shall be under no obligation to observe or perform any covenant of this Lease on its part to be observed or performed which accrues after the date of any Event of Default by Tenant unless and until the Event of Default is cured by Tenant, it being understood and agreed that the performance by Landlord of its obligations under this Lease are expressly conditioned upon Tenant's full and timely performance of its obligations under this Lease. The various rights and remedies reserved to Landlord in this Lease or otherwise shall be cumulative and, except as otherwise provided by California law, Landlord may pursue any or all of its rights and remedies at the same time.

(c) No delay or omission of Landlord to exercise any right or remedy shall be construed as a waiver of the right or remedy or of any breach or Event of Default by Tenant. The acceptance by Landlord of rent shall not be a (i) waiver of any preceding breach or Event of Default by Tenant of any provision of this Lease, other than the failure of Tenant to pay the particular rent accepted, regardless of Landlord's knowledge of the preceding breach or Event of Default at the time of acceptance of rent, or (ii) a waiver of Landlord's right to exercise any remedy available to Landlord by virtue of the breach or Event of Default. The acceptance of any payment from a debtor in possession, a trustee, a receiver or any other person acting on behalf of Tenant or Tenant's estate shall not waive or cure a breach or Event of Default under Section 14.1. No payment by Tenant or receipt by Landlord of a lesser amount than the rent required by this Lease shall be deemed to be other than a partial payment on account of the earliest due stipulated rent, nor shall any endorsement or statement on any check or letter be deemed an accord and satisfaction and Landlord shall accept the check or payment without prejudice to Landlord's right to recover the balance of the rent or pursue any other remedy available to it. No act or thing done by Landlord or Landlord's agents during the Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept a surrender shall be valid unless in writing and signed by Landlord. No employee of Landlord or of Landlord's agents shall have any power to accept the keys to the Premises prior to the termination of this Lease, and the delivery of the keys to any employee shall not operate as a termination of this Lease or a surrender of the Premises.

ThermoGenesis Holdings Inc. Lease

(d) Any agreement for free or abated rent or other charges, or for the giving or paying by Landlord to or for Tenant of any cash or other bonus, inducement or consideration for Tenant's entering into this Lease or any other concession agreed to by Landlord hereunder ("Inducement Provisions") shall be deemed conditioned upon Tenant's full and faithful performance of the terms, covenants and conditions of this Lease for the initial 66 month term. Upon an Event of Default under this Lease by Tenant, any such Inducement Provisions shall automatically be deemed deleted from this Lease and of no further force or effect and the amount of any rent reduction or abatement or other bonus, inducement or consideration or other concession already given by Landlord or received by Tenant as an inducement shall be immediately due and payable by Tenant to Landlord, notwithstanding any subsequent cure of said Event of Default by Tenant.

SECTION 14.3. LATE PAYMENTS.

(a) Any payment due to Landlord under this Lease, including without limitation Basic Rent, Tenant's Share of Operating Expenses or any other payment due to Landlord under this Lease whether or not designated as additional rent hereunder, that is not received by Landlord within ten (10) days following the date due shall bear interest at the maximum rate permitted by law from the date due until fully paid. The payment of interest shall not cure any breach or Event of Default by Tenant under this Lease. In addition, Tenant acknowledges that the late payment by Tenant to Landlord of Basic Rent and Tenant's Share of Operating Expenses will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult and impracticable to ascertain. Those cost may include, but are not limited to, administrative, processing and accounting charges, and late charges which may be imposed on Landlord by the terms of any ground lease, mortgage or trust deed covering the Premises. Accordingly, if any Basic Rent or Tenant's Share of Operating Expenses due from Tenant shall not be received by Landlord or Landlord's designee within ten (10) days following the date due, then Tenant shall pay to Landlord, in addition to the interest provided above, a late charge, which the Tenant agrees is reasonable, in a sum equal to five percent (5%) of the amount overdue for each delinquent payment Acceptance of a late charge by Landlord shall not constitute a waiver of Tenant's breach or Event of Default with respect to the overdue amount, nor shall it prevent Landlord from exercising any of its other rights and remedies.

(b) Following each second installment of Basic Rent within any twelve (12) month period that is not paid within ten (10) days following the date due, Landlord shall have the option (i) to require that beginning with the first payment of Basic Rent next due, Basic Rent no longer be paid in monthly installments but shall be payable quarterly three (3) months in advance and/or (ii) to require that Tenant increase the amount, if any, of the Security Deposit by one hundred percent (100%). Should Tenant deliver to Landlord, at any time during the Term, two (2) or more insufficient checks, the Landlord may require that all monies then and thereafter due from Tenant be paid to Landlord by cashier's check. If any check for any payment to Landlord hereunder is returned by the bank for any reason, such payment shall not be deemed to have been received by Landlord and Tenant shall be responsible for any applicable late charge, interest payment and the charge to Landlord by its bank for such returned check. Nothing in this Section shall be construed to compel Landlord to accept Basic Rent, Tenant's Share of Operating Expenses or any other payment from Tenant if there exists an Event of Default unless such payment fully cures any and all such Events of Default. Any acceptance of any such payment shall not be deemed to waive any other right of Landlord under this Lease. Any payment by Tenant to Landlord may be applied by Landlord, in its sole and absolute discretion, in any order determined by Landlord to any amounts then due to Landlord.

SECTION 14.4. RIGHT OF LANDLORD TO PERFORM. All covenants and agreements to be performed by Tenant under this Lease shall be performed at Tenant's sole cost and expense and without any abatement of rent or right of set-off. If Tenant fails to pay any sum of money, other than rent payable to Landlord, or fails to perform any other act on its part to be performed under this Lease, and the failure continues beyond any applicable grace period set forth in Section 14.1, then in addition to any other available remedies, Landlord may, at its election make the payment or perform the other act on Tenant's part and Tenant hereby grants Landlord the right to enter onto the Premises in order to carry out such performance. Landlord's election to make the payment or perform the act on Tenant's part shall not give rise to any responsibility of Landlord to continue making the same or similar payments or performing the same or similar acts nor shall Landlord be responsible to Tenant for any damage caused to Tenant as the result of such performance by Landlord. Tenant shall, promptly upon demand by Landlord, reimburse Landlord for all sums paid by Landlord and all necessary incidental costs, together with interest at the maximum rate permitted by law from the date of the payment by Landlord.

SECTION 14.5. DEFAULT BY LANDLORD. Landlord shall not be deemed to be in default in the performance of any obligation under this Lease, and Tenant shall have no rights to take any action against Landlord, unless and until Landlord has failed to perform the obligation within thirty (30) days after written notice by Tenant to Landlord specifying in reasonable detail the nature and extent of the failure; provided, however, that if the nature of Landlord's obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be deemed to be in default if it commences performance within the thirty (30) day period and thereafter diligently pursues the cure to completion. In the event of Landlord's default under this Lease, Tenant's sole remedies shall be to seek damages or specific performance from Landlord, provided that any damages shall be limited to Tenant's actual out-of-pocket expenses and shall in no event include any consequential damages, lost profits or opportunity costs. Landlord shall be deemed to be in default if the Tenant Requested Improvements are not completed within twelve (12) months from the Commencement of the Lease. Under such event, Tenant has the option to terminate the lease without any penalty.

SECTION 14.6. EXPENSES AND LEGAL FEES. All sums reasonably incurred by Landlord in connection with any Event of Default by Tenant under this Lease or holding over of possession by Tenant after the expiration or earlier termination of this Lease, or any action related to a filing for bankruptcy or reorganization by Tenant, including without limitation all costs, expenses and actual accountants, appraisers, attorneys and other professional fees, and any collection agency or other collection charges, shall be due and payable to Landlord on demand, and shall bear interest at the rate often percent (10%) per annum. Should either Landlord or Tenant bring any action in connection with this Lease, the prevailing party shall be entitled to recover as a part of the action its reasonable attorneys' fees, and all other costs. The prevailing party for the purpose of this Section shall be determined by the tier of the facts.

SECTION 15.1. HOLDING OVER. This Lease shall terminate without further notice upon the expiration of the Term, as may be extended for the Extension of the Terms et firth in Article I, Section 18, and any holding over by Tenant after the expiration shall not constitute a renewal or extension of this Lease, or give Tenant any rights under this Lease, except when in writing signed by both parties. Any period of time following the Expiration Date or early termination of this Lease required for Tenant to remove its property or to place the Premises in the condition required pursuant to Section 15.3 (or for Landlord to do so if Tenant fails to do so) shall be deemed a holding over by Tenant. If Tenant holds over for any period after the Expiration Date (or earlier termination) of the Term without the prior written consent of Landlord, such possession shall constitute a tenancy at sufferance only and an Event of Default under this Lease; such holding over with the prior written consent of Landlord shall constitute a month-to-month tenancy commencing on the first (1st) day following the termination of this Lease and terminating thirty (30) days following delivery of written notice of termination by either Landlord or Tenant to the other. In either of such events, possession shall be subject to all of the terms of this Lease, except that the monthly Basic Rent shall be two hundred percent (200%) of the greater of (a) the Basic Rent for the month immediately preceding the date of termination or (b) the then currently scheduled Basic Rent for comparable space in the Project. The acceptance by Landlord of monthly holdover rental in a lesser amount shall not constitute a waiver of Landlord's right to recover the full amount due for any holdover by Tenant, unless otherwise agreed in writing by Landlord. If Tenant fails to surrender the Premises upon the expiration of this Lease despite demand to do so by Landlord, Tenant shall indemnify and bold Landlord harmless from all loss or liability, including without limitation, any claims made by any succeeding tenant relating to such failure to surrender. The foregoing provisions of this Section are in addition to and do not affect Landlord's right of re-entry or any other rights of Landlord under this Lease or at law.

SECTION 15.2. MERGER ON TERMINATION. The voluntary or other surrender of this Lease by Tenant, or a mutual termination of this Lease, shall terminate any or all existing subleases unless Landlord, at its option, elects in writing to treat the surrender or termination as an assignment to it of any or all subleases affecting the Premises.

SECTION 15.3. SURRENDER OF PREMISES; REMOVAL OF PROPERTY. Subject to the provisions of Section 7.3 of this Lease and of the Work Letter, if any, attached hereto, upon the Expiration Date or upon any earlier termination of this Lease, Tenant shall quit and surrender possession of the Premises to Landlord in as good order, condition and repair as when received or as hereafter may be improved by Landlord or Tenant, reasonable wear and tear and repairs; which are Landlord's obligation excepted, and shall, without expense to Landlord, remove or cause to be removed from the Premises all personal property, removable trade fixtures, and equipment and debris and perform all work required under Section 7.3 of this Lease and/or the Work Letter, if any, attached hereto, as to Replacements of Non-Standard Improvements and removal of Alterations, except for any items that Landlord may by written authorization allow to remain. Tenant shall repair all damage to the Premises resulting from the removal, which repair shall include the patching and filling of holes and repair of structural damage, provided that Landlord may instead elect to repair any structural damage at Tenant's expense. If Tenant shall fail to comply with the provisions of this Section, Landlord may affect the removal and/or make any repairs, and the cost to Landlord shall be additional rent payable by Tenant upon demand. If Tenant fails to remove Tenant's personal property from the Premises upon the expiration of the Term, Landlord may remove, store, dispose of and/or retain such personal property, at Landlord's option, in accordance with then applicable laws, all at the expense of Tenant If requested by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an instrument in writing releasing and quitclaiming to Landlord all right, title and interest of Tenant in the Premises.

SECTION 22.1. NONDISCLOSURE OF LEASE TERMS. Tenant acknowledges and agrees that the terms of this Lease are confidential and constitute proprietary information of Landlord.

EXHIBIT X. WORK LETTER

BUILD TO SUIT

The Tenant Requested Improvement work (the "Tenant Requested Improvements") shall consist of the work, including work in place as of the date hereof, required to complete the improvements to the Premises as shown in the GMP renovation space plan (the "Plan") prepared by CleanAir Solution, Inc., dated February 24, 2022. The Tenant Requested Improvements shall be performed by a contractor selected and approved by both Landlord and Tenant in accordance with the requirements and procedures set forth below.

I. ARCHITECTURAL AND CONSTRUCTION PROCEDURES.

A. Landlord shall pay up to the full amount towards the cost of the Tenant Requested Improvements as outlined in the Plan dated February 24, 2022. Any additional cost exceeding the total amount of the Plan, including but not limited to, equipment and costs resulting from Changes (as hereinafter defined) requested by Tenant shall be borne solely by Tenant. Unless otherwise specified in the Plan, all materials, specifications and finishes utilized in constructing the Tenant Requested Improvements shall be Landlord's building standard tenant improvement materials and specifications for the Plan as set forth in Schedule I attached hereto. Should Landlord submit any additional plans, equipment specification sheets, or other matters to Tenant for approval or completion in connection with the Tenant Requested Improvements, Tenant shall respond in writing, as appropriate, within five (5) days unless a shorter period is provided herein. Tenant shall not unreasonably withhold its approval of any matter, and any disapproval shall be limited to items not previously approved by Tenant in the Plan or otherwise.

B. In the event that Tenant requests in writing a revision to the Plan ("Change"), and Landlord so approves such Change as provided in Section I.C below, Landlord shall advise Tenant by written change order as soon as is practical of any increase in the cost to complete the Tenant Requested Improvements and/or any Tenant Delay that such Change would cause. Tenant shall approve or disapprove such change order and Tenant Delay, if any, in writing within two (2) days following Tenant's receipt of such change order. If Tenant approves any such change order, Landlord, at its election, may either (i) require as a condition to the effectiveness of such change order that Tenant pay the increase in the cost to complete attributable to such change order concurrently with delivery of Tenant's approval of the change order, or (ii) increase Tenant's rent payment. If Tenant disapproves any such change order, Tenant shall nonetheless be responsible for the reasonable architectural and/or planning fees incurred in preparing such change. Landlord shall have no obligation to interrupt or modify the Tenant Requested Improvements pending Tenant's approval of a change order, but if Tenant fails to timely approve a change order, Landlord may (but shall not be required to) suspend the applicable Tenant Requested Improvements, in which event any related critical path delays because of such suspension shall constitute Tenant Delays hereunder.

C. Landlord may consent in writing, in its sole and absolute discretion, to Tenant's request for a Change, including any modification of the Tenant Requested Improvements, if requested in writing by Tenant. In addition, Landlord agrees that it shall not unreasonably withhold its consent to Tenant's requested Changes to previously approved Tenant Requested Improvements, unless Landlord determines, in its sole and absolute discretion, that such requested Change (i) is of a lesser quality than the Plan previously approved by Landlord, (ii) fails to conform to applicable governmental requirements, (iii) would result in the Premises requiring building services beyond the level normally provided to other tenants, (iv) would delay construction of the Tenant Requested Improvements beyond the Estimated Commencement Date and Tenant declines to accept such delay in writing as a Tenant Delay, (v) interferes in any manner with the proper functioning of, or Landlord's access to, any mechanical, electrical, plumbing or HVAC systems, facilities or equipment in or serving the Building, or (vi) would have an adverse aesthetic impact to the Premises or cause additional expenses to Landlord in reletting the Premises. The cost to complete the Tenant Requested Improvements shall be borne by Landlord, provided it is within the budget outlined in the Plan dated February 24, 2022. All Improvements shall become the property of Landlord and shall be surrendered with the Premises at the end of the Term; except that Landlord may, by notice to Tenant given either prior to or following the expiration or termination of the Lease, require Tenant either to remove all or any of the Improvements. Any such removals, repairs and replacements by Tenant shall be completed by the Expiration Date, or sooner termination of this Lease, or within ten (10) days following notice to Tenant if such notice is given following the Expiration Date or sooner termination.

ThermoGenesis Holdings Inc. Lease

D. Notwithstanding any provision in the Lease to the contrary, and not by way of limitation of any other rights or remedies of Landlord, if Tenant fails to comply with any of the time periods specified in this Work Letter, fails otherwise to approve or reasonably disapprove any submittal within the time period specified herein for such response (or if no time period is so specified, within five (5) days following Tenant's receipt thereof), requests any Changes, furnishes inaccurate or erroneous specifications or other information, or otherwise delays in any manner the completion of the Tenant Requested Improvements (including without limitation by specifying materials that are not readily available) or the issuance of an occupancy certificate (any of the foregoing being referred to in this Lease as a "Tenant Delay"), then Tenant shall bear any resulting additional construction cost or other expenses above the budget as in the Plan, and the Commencement Date of this Lease shall be deemed to have occurred for all purposes, including without limitation Tenant's obligation to pay rent, as of the date Landlord reasonably determines that it would have been able to deliver the Premises to Tenant but for the collective Tenant Delays. Should Landlord determine that the Commencement Date should be advanced in accordance with the foregoing, it shall so notify Tenant in writing. Landlord's determination shall be conclusive unless Tenant notifies Landlord in writing, within five (5) days thereafter, of Tenant's election to contest same by arbitration pursuant to the provisions of Section II below. Pending the outcome of such arbitration proceedings, Tenant shall make timely payment of all rent due under this Lease based upon the Commencement Date set forth in the aforesaid notice from Landlord.

E. Landlord shall permit Tenant and its agents to enter the Premises prior to the Commencement Date of the Lease in order that Tenant may install fixtures, furniture and cabling through Tenant's own contractors. Any such work shall be subject to Landlord's prior written approval, and shall be performed in a manner and upon terms and conditions and at times satisfactory to Landlord's representative.

F. Landlord hereby designates Xxxxx Xxxxxxxxx ("Tenant Requested Improvements Construction Representative"), Telephone No. 000-000-0000 Ext. 101, as its representative for all construction matters related to the Tenant Requested Improvements, including but not by way of limitation, for purposes of applying permits, developing construction plans.

Landlord agrees to provide funds towards the constructing the Tenant Requested Improvements in the amount of no more than Three Million Dollars ($3,000,000) (the "Landlord Contribution"), based on $35.00 per rentable square foot of the Premises upon completion of the Tenant Requested Improvements, with any excess cost of the Tenant Requested Improvements to be borne solely by Tenant. If the actual cost of completion of the Tenant Requested Improvements is less than the maximum amount provided for the Landlord's Contribution, such savings shall inure to the benefit of Landlord and Tenant shall not be entitled to any credit or payment.

B. Landlord agrees to pay the Landlord Contribution, excluding any Changes requested by the Tenant, any costs attributable to Tenant Delays and the amount, if any, by which aggregate Landlord Contribution of the Tenant Requested Improvements exceeds Three Million Dollars. The amounts to be paid by Tenant for the Tenant Requested Improvements pursuant to this Section II.C. are sometimes cumulatively referred to herein as the "Tenant's Contribution".

Unless expressly authorized in writing by Landlord, the Completion Cost shall not include (and no portion of the Landlord Contribution shall be paid for) any costs incurred by Tenant, including without limitation, any costs for space planners, managers, advisors or consultants retained by Tenant in connection with the Tenant Requested Improvements.

ThermoGenesis Holdings Inc. Lease

D. In the event that there is a balance to be paid by Tenant as Tenant’s Contribution, Tenant shall pay to Landlord in full the amount of the Tenant's Contribution. The balance of all sums due and owing and not otherwise paid by Tenant shall be due and payable on or before the rent due in the following month. If Tenant defaults in the payment of any sums due under this Work Letter, Landlord shall (in addition to all other remedies) have the same rights as in the case of Tenant's failure to pay rent under the Lease, including, without limitation, the right to terminate this Lease and recover damages from Tenant and/or to charge a late payment fee and to collect interest on delinquent payments, and Landlord may (but shall not be required to) suspend the Tenant Requested Improvements following such default, in which event any delays because of such suspension shall constitute Tenant Delays hereunder.

III. RATE ADJUST AND EARLY TERMINATION

A. In the event that there is a Tenant’s Default or earlier termination of the Lease during the initial 66 month term, Tenant is responsible to pay back, in full amount, the Landlord Contribution toward the Tenant Requested Improvements.

III. DISPUTE RESOLUTION

A. All claims or disputes between Landlord and Tenant arising out of, or relating to, this Work Letter shall be decided by the JAMS/ENDISPUTE ("JAMS"), or its successor, with such arbitration to be held in Orange County, California, unless the parties mutually agree otherwise. Within ten (10) business days following submission to JAMS, JAMS shall designate three arbitrators and each party may, within five (5) business days thereafter, veto one of the three persons so designated. If two different designated arbitrators have been vetoed, the third arbitrator shall hear and decide the matter. If less than two (2) arbitrators are timely vetoed, JAMS shall select a single arbitrator from the non-vetoed arbitrators originally designated by JAMS, who shall hear and decide the matter. Any arbitration pursuant to this section shall be decided within thirty (30) days of submission to JAMS. The decision of the arbitrator shall be final and binding on the parties. All costs associated with the arbitration shall be awarded to the prevailing party as determined by the arbitrator.

B. Notice of the demand for arbitration by either party to the Work Letter shall be filed in writing with the other party to the Work Letter and with JAMS and shall be made within a reasonable time after the dispute has arisen. The award rendered by the arbitrator shall be final, and judgment may be entered upon it in accordance with applicable law in any court having jurisdiction thereof. Except by written consent of the person or entity sought to be joined, no arbitration arising out of or relating to this Work Letter shall include, by consolidation, joinder or in any other manner, any person or entity not a party to the Work Letter unless (1) such person or entity is substantially involved in a common question of fact or law, (2) the presence of such person or entity is required if complete relief is to be accorded in the arbitration, or (3) the interest or responsibility of such person or entity in the matter is not insubstantial.

C. The agreement herein among the parties to arbitrate shall be specifically enforceable under prevailing law. The agreement to arbitrate hereunder shall apply only to disputes arising out of, or relating to, this Work Letter, and shall not apply to other matters of dispute under the Lease except as may be expressly provided in the Lease.
