(c) The
Over-Allotment Option granted pursuant to this Section 2.2 may be exercised by the Representative as to all (at any time) or any part
(from time to time) of the Option Securities within 45 days after the Execution Date. An Underwriter will not be under any obligation
to purchase any Option Securities prior to the exercise of the Over-Allotment Option by the Representative. The Over-Allotment Option
granted hereby may be exercised by the giving of oral notice to the Company from the Representative, which must be confirmed in writing
by overnight mail or facsimile or other electronic transmission setting forth the number of Option Shares and/or Option Warrants to be
purchased and the date and time for delivery of and payment for the Option Securities (each, an “Option Closing Date”)
which will not be later than the earlier of (i) 45 days after the Execution Date and (ii) one (1) full Business Day after the date of
the notice or such other time as shall be agreed upon by the Company and the Representative, at the offices of Harter Secrest or at such
other place (including remotely by facsimile or other electronic transmission) as shall be agreed upon by the Company and the Representative.
If such delivery and payment for the Option Securities does not occur on the Closing Date, each Option Closing Date will be as set forth
in the notice. Upon exercise of the Over-Allotment Option, the Company will become obligated to convey to the Underwriters, and, subject
to the terms and conditions set forth herein, the Underwriters will become obligated to purchase, the number of Option Shares and/or Option
Warrants specified in such notice. The Representative may cancel the Over-Allotment Option at any time prior to the expiration of the
Over-Allotment Option by written notice to the Company.
