lease than the March 1, 1994 agreement, Highland Industrial Park offers the following option renewals. Subject to the provisions hereof, Lessor expressly gives and grants to Lessee the right, option and privilege of extending the leasehold term
of this lease one (1) time for an additional period of ten (10) years and then four (4) times for an additional period of five (5) years each time (that is, one (1) ten (10) year extension and four (4) five
(5) year extensions in addition to the original leasehold term herein granted), upon the same terms and conditions as herein set out (except as hereinafter provided), all of which shall apply to such extended term to

---

the same extent and as fully as if this lease had been written for the period of time covering both the original term and the extended term or terms provided
in this option of extension, and in such event the word term in this agreement shall mean and refer to the original term as so extended. The option herewith granted by Lessor to Lessee to extend the term of this lease one (1) time for an
additional period of ten (10) years and four (4) times for an additional five (5) years each time shall expire, and be of no further force and effect, unless exercised by Lessee by written notice to Lessor on or before the date which
is ninety (90) days prior to the expiration of the term then in effect. In the event Lessee elects to exercise any such option of extension, then the giving of the above described notice by Lessee so notifying Lessor in writing, if given within
the time hereinabove provided, shall operate to automatically extend this lease for an additional term without further action on the part of either of the parties hereto; provided that failure on the part of Lessee to give such written notice to
Lessor within such time shall conclusively be deemed to be an election by Lessee to waive such option of renewal and such option shall then be null and void.

(b) Notwithstanding any of the above provisions, it is agreed that:

(1) Such option may be exercised only
if at the time of such exercise this lease is in full force and effect and Lessee is not in default in the performance of any of the terms or provisions of this lease.

(2) If such option is exercised to extend this lease one or more times for successive ten (10) year and five (5) year periods, this lease shall continue in effect in accordance with the terms and provisions
hereof except that during the ten (10) year extension and each successive five (5) year option, the monthly rental therefore, payable monthly in advance during said extended term, shall be escalated by 3% year over year per the attached
schedule.
