M The annual base rent as provided in Section J above does no! include any charge for use of approximately 3,272 square feet (including 4.7% common area) shown as the hatched area on the mutually agreed upon plan attached hereto (the “Hatched Area”) because LESSEE has represented that LESSEE (i) will not use the Hatched Area and (ii) intends only to use the approximately 3,890 square feet (including 4.7% common area) of unhatched area. LESSEE may, however, elect at any time to use the Hatched Area or any portion thereof, and if LESSEE does use the Hatched Area or any portion thereof in any way other than to occasionally pass through the Hatched Area, then the annual base rent shall be immediately increased by $111,084 for the balance of the lease term.

Alternatively, LESSOR may, at its election and expense, separate (the utilities serving the Hatched Area and the remainder of Suite B, in which case, LESSEE will not receive a reduction in base rent.

P. LESSOR may elect to cancel this lease for any reason or no reason at all, to be effective on or after December 30, 2016, by serving LESSEE with not less than 90 days’ prior written notice to that effect.

Paragraph M of the Rider to Lease is hereby deleted and the following shall not apply. The annual base rent as provided in Section 2 above does not include any charge for use of approximately 2,029 square feet (including 4.7% common area) shown as the hatched area on the attached plan (the “Hatched Area”) because LESSEE has represented that LESSEE (i) will not use the Hatched Area and (ii) intends only to use the approximately 3,890 square feet (including 4.7% common area) of unhatched area and the approximately 1,243 square feet (including 4.7% common area) shows as the cross-hatched area on the attached plan (the “Cross-Hatched Area). LESSEE may, however, elect at any time to use the Hatched Area or any portion thereof, and if LESSEE does use the Hatched Area or any portion thereof in any way other than to pass through the Hatched Area, then the annual based rent shall be immediately increased by $56,272 for the balance of the lease term.

Paragraph N of the Rider to Lease is hereby deleted and the following shall now apply. If LESSEE has not previously elected to use the Hatched Area or any portion thereof, LESSOR may, at LESSOR’s sole expense, remove the Hatched Area or portion(s) thereof from the premises from time to time during the lease term by serving LESSEE with at least five days’ prior written notice to that effect. LESSEE shall move its furniture, furnishings, equipment, inventory, and other property as requested by LESSOR to enable LESSOR to carry out any modifications required for such removal, and LESSEE shall indemnify and hold harmless LESSOR and LESSOR’s agents, employees and contractors from any and all injury or damage arising out of this work. In the event LESSOR removes the Hatched Area or portion(s) thereof from the premises, the size of the premises shall be decreased by the number of square feet so removed (including 4.7% common area) and the then-current annual base rent shall remain the same.

Paragraph O of the Rider to Lease is hereby deleted and the following shall now apply. The parties acknowledge and agree that the utilities serving the Hatched Area are not separated from the utilities serving the remainder of Suite B, and that LESSEE shall pay all utility charges for the entire suite. If LESSOR leases all or any portion of the Hatched Area to a third party for any use other than storage, LESSEE’s then-current annual rent shall be reduced by the product of the number of square feet so removed and $1.50 throughout the third party’s occupancy (to be apportioned on a monthly basis) in order to compensate LESSEE for such third party’s utility usage. Alternatively, LESSOR may, at its election and expense, separate the utilities serving the Hatched Area or the applicable portion thereof, as the case may be, and the remainder of Suite B, in which case, LESSEE will not receive a reduction in base rent.

If LESSEE has not elected to use the Hatched Area or any portion thereof as provided in Section 6 above, and LESSOR has not removed the Hatched Area or any portion thereof as provided in Section 7 above, LESSOR may elect to remove the Cross-Hatched Area or any portion thereof from the premises at any time during the lease term by serving LESSEE with at least 60 days’ prior written notice to that effect. LESSOR’s notice shall specify (i) the configuration of the Cross-Hatched Area to be removed, (ii) the effective date of such removal (the “Recapture Area”). The square footage of the Relocation Area shall not be less than the square footage of the Cross-Hatched Area removed by LESSOR. Effective on the Recapture Date, (a) the square footage of the Cross-Hatched Area shall be reduced in accordance with the reconfiguration in subsection (i) above, and (b) the square footage of the Hatched Area shall be reduced by the number of square feet in the Relocation Area, in accordance with subsection (iii) above without any increase or decrease in base rent. LESSEE shall move its furniture, furnishings, equipment, inventory, and other property as requested by LESSOR to enable LESSOR carry out any modifications required to remove the Cross-Hatched Area or the applicable portion thereof, as the case may be, from the premises, and LESSEE shall indemnify and hold harmless LESSOR and LESSOR’s agents, employees, and contractors from any and all injury or damage arising out of this work. LESSEE shall vacate the Cross-Hatched Area or the applicable portion thereof, as the case may be, on or before 12:00 PM on the Recapture Date, and any extended occupancy of the Cross-Hatched Area or the applicable portion thereof, as the case may be, shall be governed by Section 22 of the lease. All other terms of Section 6 above shall continue to apply. Time is of the essence.

This extension shall not bind any party in any manner whatsoever until it has been executed by all parties. All other terms of the lease shall continue to apply, and to the extent any inconsistency exists between this extension and the lease, including any prior amendments and extensions, the terms herein shall control and supersede any earlier provisions. In witness whereof, LESSOR and LESSEE, intending to be legally bound, have caused this extension to be executed this 28th day of February, 2017.
