OPTION TO RENEW THE FOLLOWING IS HEREBY ADDED TO THE LEASE: Provided Tenant has complied with all the terms and conditions of the Lease and is not in default or breach of its obligations thereunder, Landlord grants to Tenant the option to renew the term of the Lease for two additional (5) year periods ("Renewal Term(s)") to commence at the end of the Lease Term or Renewal Term. Tenant must exercise its option to renew by delivering written notice of such election to Landlord at its place of business at least One Hundred Eighty (180) days prior to the expiration of the current Lease Term or the First Renewal Term, as the case may be. The terms and conditions of the Renewal Term shall be on the same terms set forth in the Lease except that all rent, including but not limited to, all Additional Rent and other charges payable during the Lease Term shall be at the then current prevailing market rate (the "Prevailing Market Rate") at the time the applicable Renewal Term commences and there shall be no additional Renewal Terms other than those provided above. Prevailing Market Rate shall be computed as of the date in question with consideration being given to then-current annual basic rental charges and other additional rent for new leases then currently, or within the preceding twelve (12) month period, being or that have been negotiated or executed in comparable space located in the Building, or if no new leases are then currently, or within the preceding twelve (12) month period, being or that have been negotiated or executed then the comparison shall be made based on comparable space located elsewhere in first-class office buildings comparably aged and equipped located in Coconut Grove 10 11 or, if no comparables are available, in Miami's Central Business District. Notwithstanding anything to the contrary herein contained, the parties hereby agree that, at the time Landlord gives its initial determination of any Prevailing Market Rate, Landlord shall have the right, exercisable by written notice to Tenant: (i) to change the base taxes to an amount equal to the actual amount of taxes for the immediately preceding tax year for which Landlord has actual tax data, and (ii) to change base operating expenses and/or building energy utility cost base from the respective amounts to an amount or amounts, as the case may be, equal to the actual amount of operating expenses and/or the actual amount of building energy/utility costs, as the case may be, for the immediately preceding operating year. In determining Prevailing Market Rate, the amount of base taxes, base operating expenses and/or building energy utility cost base and electricity shall be taken into account and given effect. Landlord shall initially designate a Prevailing Market Rate and shall furnish data in support of such designation to Tenant (the "Landlord's Designated Amount"). If Tenant disagrees with Landlord's Designated Amount, then Tenant shall have the right by written notice given within thirty (30) days after Tenant has been notified of Landlord's Designated Amount, to submit to Landlord the amount that Tenant considers to be the Prevailing Market Rate, together with data in support thereof (the "Tenant's Designated Amount"). Thereafter, the parties shall have a period of thirty (30) days to engage in discussions for purposes of arriving at a mutually acceptable amount. If the parties are unable to do so, then promptly following the expiration date of such thirty (30) day period, the parties shall submit Landlord's Designated Amount and Tenant's Designated Amount to the nearest local office of the American Arbitration Association (the "Association") so that either Landlord's Designated Amount or Tenant's Designated Amount is selected as the amount which will constitute the Prevailing Market Rate under the Lease. In that regard, it is understood and agreed that no amount other than the Landlord's Designated Amount or the Tenant's Designated Amount may be selected by the Association. Each party shall equally share the costs of arbitration hereunder. The decision of the Association shall be binding on the parties and shall be incorporated into the terms of the Lease. In the event the matter is submitted to the Association for resolution, then during the pendency of the dispute, Tenant shall pay rent under the Lease to the Landlord in an amount equal to Tenant's Designated Amount (the "Tenant's Rent Payment") and Tenant shall pay the difference, on the same due date as the rent is due under the Lease, between Tenant's Designated Amount and Landlord's Designated Amount into the trust account of Tenant's counsel ("Escrow Agent") to be held pending resolution of the dispute. Upon resolution of the dispute and determination of the Prevailing Market Rate by the Association and in the event the Prevailing Market Rate set by the 11 12 Association differs from the Tenant's Rent Payment, the Tenant shall pay and/or cause Escrow Agent to pay to Landlord any deficiency in unpaid rent or Landlord shall pay to Tenant any overpaid rent within five (5) business days of the Association's written decision and a failure to pay such amount during such time period shall be deemed a default of such party's obligations under the Lease. Furthermore, in the event either Landlord or Tenant fails to pay 1/2 of the arbitration costs within five (5) business days from the earlier of (i) any invoice due date or (ii) any request for payment made by the Association or any arbitrator, the same shall be a default of that party's obligations under the Lease. O. STORAGE SPACE: Tenant shall have the right to the use of that certain storage space located on the 7th floor of the building's garage hereby designated as Storage Space No 12 per the attached plan (Exhibit F) consisting of 911 rentable square feet at the rate of $10.00 square feet or Seven Hundred Fifty Nine and 16/100 Dollars ($759.16) per month plus applicable sales tax. Said rate shall increase annually by $0.50 per square foot. P. SIGNAGE Provided that Tenant is not in default of any term, condition or covenant of the Lease beyond all applicable notice and grace periods, Tenant shall have the right, at its sole cost and expense, to install rooftop signage on the building. Prior to installation, Tenant shall submit its proposed signage plans (including design, content, location and electrical plans) for Landlord's approval, which may be withheld in Landlord's sole and absolute discretion. Said signage must comply with Landlord's signage criteria and all relevant municipal codes and regulations. Tenant shall be responsible, at Tenant's sole cost and expense, for obtaining all permits and approvals required to erect and maintain said signage. Additionally, Tenant, at its sole cost and expense, shall maintain and remove signage, if necessary. Upon the expiration or earlier termination of this Lease, if requested by Landlord, Tenant shall, at Tenant's sole cost and expense, remove such signage.
