Lessee shall have the burden of proof in establishing that such latent defect is a breach of Lessor's warranty and otherwise meets the requirements of the preceding sentence."

        5.     Paragraph 2.6 is hereby added to the Lease:

        "Lessor shall allow Lessee to use the existing modular furniture, improvements, carpet, window coverings, file cabinets, computer room equipment, and kitchen appliances (collectively "Existing Equipment") for the Original Term of the tease and any Option Terms.

Prior to the Commencement Date, Lessee at its sole expense shall conduct an inventory of the Existing Equipment, which shall be subject to Lessor's reasonable approval. Upon approval of the Inventory, Lessee shall 'tag' each; item of the Existing Equipment in a manner sufficient to identify it as Existing Equipment. Lessee shall provide Lessor with a copy of the inventory list and identification information."

        6.     Paragraph 3.5 is hereby added to the Lease:

        "3.5 Option to Extend.

        Lessor hereby grants to Lessee the option (the "Option") to extend the term of this Lease for one (1) additional five (5) year period (the "Option Term"), commencing when the Original Term expires upon each and all of the following terms and conditions:

        (a)   Lessee gives to Lessor, and Lessor actually receives on a date which is prior to the date that the Option Term would commence (if exercised) by at least nine (9) months, but no more than twelve (12) months, a written notice of the exercise of the option to extend this Lease for the Option Term. If the notification of the exercise of the option is not so given and received, the option shall automatically expire;

        (b)   All of the provisions of Paragraph 39 of this Lease are conditions of this Option;

        (c)   All of the terms and conditions of this Lease shall apply, except that the monthly rent shall be increased to the fair market rental value for similar buildings in Westlake village at the time the Option Term commences. The fair market rental value for the first year of the Option Term shall be determined in accordance with the following procedures:

        (i)    Within fifteen (15) days of receipt by Landlord of Tenant's written exercise of the above-described (respective) option to extend the term of the Lease, Landlord shall advise Tenant in writing of Landlord's opinion of the fair market rental value of the Premises for such option Term (sometimes also referred to herein as the "Fair Market value").

        (ii)   If the proposed Fair Market Value is acceptable to Tenant, then Tenant shall so notify Landlord in writing within fifteen (15) days of receipt by Tenant of Landlord's notice of the proposed Fair Market Value. Tenant's failure to so notify Landlord, in writing, on or

2

---

before the expiration of such time period shall be deemed a waiver of its right to so challenge Landlord's determination of Fair Market Value.

        (iii)  In the event Tenant challenges Landlord's opinion of the Fair Market Value of the Premises, Tenant shall notify Landlord thereof in writing within fifteen (15) days of receipt by Tenant of Landlord's notice of the proposed Fair Market Value, and the Fair Market Value of the Premises shall be determined by appraisal in accordance with the provisions hereof. Within thirty (30) days following Tenant's notice to Landlord thereof, both Landlord and Tenant shall appoint a reputable licensed real estate broker and shall give written notice of the name and address of such broker to the other party to this Lease. The failure by either party to timely appoint a broker and notify the other party thereof as provided in the immediately preceding sentence shall be deemed a waiver by the failing party of the right to have the Fair Market Value determined by more than one broker. The two brokers thus appointed shall, within ten (10) days after such appointment, themselves appoint a third broker and serve written notice of the broker so appointed upon each of the parties. All brokers appointed hereunder must have at least five (5) years experience in leasing retail and commercial properties within Westlake Village and be qualified by education and experience to appraise properties. The broker(s) so appointed shall meet at the earliest time practicable, but in no event more than ten (10) days after the appointment of all of the required broker(s), for the purpose of determining the fair market rental value of the Premises. The decision of the majority of said broker(s) shall constitute the vote of the broker(s) and shall be binding on both of the parties hereto. In the event two of the brokers do not agree on the fair market rental value of the Premises, the average of the two closest appraisals of the fair market rental value of the Premises shall be the Fair Market Value of the Premises for purposes of this Paragraph 3.5. The brokers shall, to the extent possible, base their determination of Fair Market Value upon the then current fair market rental value of comparable buildings of similar size and improvements then, available for lease in Westlake Village. Tenant and Landlord shall each pay the cost and expense of its selected broker, with the cost of the third broker to be borne equally between Landlord and Tenant. During the period of time the parties are determining the Fair Market Value, Tenant shall continue to pay Landlord as a credit against rent due the monthly Base Rent payable the preceding Lease Year. The brokers' determination of the Fair Market Value shall be utilized as the basis for determining the monthly Base Rent for the first year of the Option Term.

        (iv)  if the Fair Market Value for the Premises as determined herein is greater than the monthly Base Rent paid by Tenant during the period of time following the end of the last Lease Year of the Original Term of the Lease, but before the Fair Market Value is determined, then Tenant shall, within thirty (30) days following the determination of the Fair Market Value, pay to Landlord the amount of underpaid sums during said period.

        (v)   Notwithstanding any terms herein to the contrary, in no event shall the monthly Base Rent for the first year of the Option Term be less than monthly Base Rent payable during the immediately preceding Lease Year.

        (d)   For the second Lease Year of the Option Term and each Lease Year thereafter, the monthly Base Rent shall be increased by one hundred three percent (103%) of the monthly Base Rent payable the preceding Lease Year."

Lessee shall be responsible, at its sole cost and expense, for the repair and maintenance of any such items installed by Lessee and for any damage to the roof, building or Common Area arising from the installation and maintenance of such items, and shall remove at the expiration or termination of the Lease, at Lessee's sole cost and expense, any items installed by Lessee (provided at Lessor's election, such fiber optics cable shall remain with the Premises) and shall restore the Premises to its original condition as of the Commencement Date of this Lease.

        " .. . . provided Lessor shall, when providing Lessee with written notice of its consent to Lessee Owned Alterations or Utility Installations, indicate whether it may require such removal; Lessor's failure to so advise Lessee shall be deemed Lessor's election not to require such removal."

        12.   Paragraph 7.5 is hereby added to the Lease:
