Agreement

NOW, THEREFORE, in consideration of the foregoing, and of the mutual covenants set forth herein and of other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

Scope of Amendment; Defined Terms. Except as expressly provided in this Amendment, the Existing Lease shall remain in full force and effect. Should any inconsistency arise between this Amendment and the Existing Lease as to the specific matters which are the subject of this Amendment, the terms and conditions of this Amendment shall control. All capitalized terms used in this Amendment and not defined herein shall have the meanings set forth in the Existing Lease unless the context clearly requires otherwise; provided, however, that the term “Lease” as used herein and, from and after the Execution Date, in the Existing Lease shall refer to the Existing Lease as modified by this Amendment.

Extension of Term. Lessor and Lessee acknowledge and agree that, notwithstanding any provisions of the Existing Lease to the contrary, the current Term pursuant to the Existing Lease will expire on August 31, 2024, and that the Term of the Lease of the Existing Premises is hereby further extended for the period of seventy two (72) months (the “Extended Term”) commencing on September 1, 2024 (the “Extension Commencement Date”) and expiring August 31, 2030 (hereafter, the “Termination Date”), unless sooner terminated pursuant to the terms of the Lease. This extension is with respect to the entire Premises. This extension is further conditioned upon and subject to the same conditions, terms, covenants and agreements contained in the Existing Lease except as otherwise provided in this Amendment. Lessor and Lessee acknowledge and agree that this Amendment provides all rights and obligations of the parties with respect to extension of the current Term, whether or not in accordance with any other provisions, if any, of the Existing Lease regarding renewal or extension, and any such provisions, options or rights for renewal or extension provided in the Existing Lease are hereby deleted as of the Execution Date.

Base Rent for Existing Premises. Lessee shall continue to pay monthly Base Rent with respect to the Existing Premises in the amount set forth in the Existing Lease up to and including the day immediately prior to the Extension Commencement Date. Effective on and after the Extension Commencement Date, the amount of monthly Base Rent due and payable by Lessee for the Existing Premises shall be as follows:


Period from/to	Monthly Base Rent
September 1, 2024 – August 31, 2025	$30,699.79
September 1, 2025 – August 31, 2026	$31,927.78
September 1, 2026 – August 31, 2027	$33,204.89
September 1, 2027 – August 31, 2028	$34,533.09
September 1, 2028 – August 31, 2029	$35,914.41
September 1, 2029 – August 31, 2030	$37,350.99

Abatement of Rent. Notwithstanding anything in this Amendment to the contrary, for so long as Lessee is not in Breach under the terms of the Lease, the Base Rent and Lessee’s

Share of Common Area Operating Expenses payable for the Existing Premises shall be fully abated for the moths of October, 2023 through February, 2024 for a total of five (5) months. The abatement set forth in this section shall be considered an Inducement Provision subject to the provisions of Paragraph 13.3 of the Original Lease.

Brokers. Notwithstanding any other provision of the Existing Lease to the contrary, Lessee represents and warrants to Lessor that Hughes Marino, Inc. (“Lessee’s Broker”) is the sole broker that negotiated and represented Lessee concerning this Amendment. Lessee hereby indemnifies and agrees to protect, defend and hold Lessor harmless from and against any claims of brokerage commissions arising out of any discussions or negotiations allegedly had by the Lessee with any other broker in connection with this Amendment. Notwithstanding any other provision of the Existing Lease to the contrary, Lessor represents and warrants to Lessee that RAF Pacifica Group (“Lessor’s Broker”) is the sole broker that negotiated and represented Lessor concerning this Amendment. Lessor hereby indemnifies and agrees to protect, defend and hold Lessee harmless from and against any claims of brokerage commissions arising out of any discussions or negotiations allegedly had by the Lessor with any other broker in connection with this Amendment. The foregoing obligations of Lessee and Lessor shall survive the expiration or sooner termination of the Lease.

Time of Essence. Without limiting the generality of any other provision of the Lease, time is of the essence to each and every term and condition of this Amendment.

Attorneys’ Fees. Each party to this Amendment shall bear its own attorneys’ fees and costs incurred in connection with the discussions preceding, negotiations for and documentation of this Amendment. In the event any party brings any suit or other proceeding with respect to the subject matter or enforcement of this Amendment or the Lease as amended, the parties acknowledge and agree that the provisions of Section 31 of the Lease shall apply.

Effect of Headings; Recitals: Exhibits. The titles or headings of the various parts or sections hereof are intended solely for convenience and are not intended and shall not be deemed to or in any way be used to modify, explain or place any construction upon any of the provisions of this Amendment. Any and all Recitals set forth at the beginning of this Amendment are true and correct and constitute a part of this Amendment as if they had been set forth as covenants herein. Exhibits, schedules, plats and riders hereto which are referred to herein are a part of this Amendment.

Entire Agreement; Amendment. This Amendment taken together with the Existing Lease, together with all exhibits, schedules, riders and addenda to each, constitutes the full and complete agreement and understanding between the parties hereto and shall supersede all prior communications, representations, understandings or agreements, if any, whether oral or written, concerning the subject matter contained in this Amendment and the Lease, as so amended, and no provision of the Lease as so amended may be modified, amended, waived or discharged, in whole or in part, except by a written instrument executed by all of the parties hereto.

Disclosure Regarding Certified Access Specialist. Pursuant to California Civil

Code Section 1938, Lessor hereby notifies Lessee that as of the date of this Amendment, neither the Existing Premises nor the Expansion Premises has undergone inspection by a “Certified Access Specialist” to determine whether the such premises meets all applicable construction-related accessibility standards under California Civil Code Section 55.53.

11.

Authority. Each party represents and warrants to the other that it has full authority and power to enter into and perform its obligations under this Amendment, that the person executing this Amendment is fully empowered to do so, and that no consent or authorization is necessary from any third party. Lessor may request that Lessee provide Lessor evidence of Lessee’s authority.

12.

Counterparts. This Amendment may be executed in two or more counterparts, which when taken together shall constitute one and the same instrument, and the signature of any party to any counterpart shall be deemed a signature to, and may be appended to, any other counterpart. Each counterpart shall be equally admissible in evidence, and each original shall fully bind each party who has executed it. The parties contemplate that they may be executing counterparts of this Amendment transmitted electronically and agree and intend that a signature delivered electronically shall bind the party so signing with the same effect as though the signature were an original signature.
