the event that, during the Restricted Period, the Representatives agree to an Exception (as defined below), the Representatives
shall be deemed to have also granted the same Exception with respect to the prohibitions set forth in this agreement that would
otherwise have applied to the undersigned with respect to the same percentage of the undersigned&rsquo;s shares of Common Stock as
the relative percentage of aggregate shares held by such party benefitting from the Exception that are being transferred pursuant to
such Exception. The provisions of this paragraph will not apply unless and until the Representatives have granted an Exception with
respect to more than 1.5%, in the aggregate (or more than 1% of outstanding shares of Common Stock with respect to any individual
holder), of outstanding shares of Common Stock subject to this agreement or a similar letter agreement, provided, however, that this
1.5% &ldquo;de minimis&rdquo; exception shall not apply to an Exception granted to a director or officer of the Company (and for the
avoidance of doubt, an Exception granted to a director or officer of the Company would cause an Exception to be automatically
granted with respect to the undersigned&rsquo;s shares of Common Stock in accordance </FONT>with the first sentence hereof) unless
such waiver is granted due to financial hardship as reasonably determined by the Representatives or if the Exception is effective
solely to permit a transfer not involving a disposition for value if the transferee agrees in writing to be bound by the same terms
described in this Agreement. Furthermore, if the release, in full or in part, of any shares of Common Stock from the restrictions of
this agreement is in connection with an underwritten follow-on offering that includes such released shares (a &ldquo;Follow-On
Offering&rdquo;), then the shares of Common Stock held by the undersigned shall be released only to the extent that the undersigned
has a contractual right to demand or require the registration of the undersigned&rsquo;s Common Stock or otherwise
&ldquo;piggyback&rdquo; on a registration statement filed by the Company in connection with the Follow-On Offering, and the
undersigned agrees to participate as a selling stockholder in the Follow-On Offering and to sell any of the shares of Common Stock
released from the restrictions of this agreement in such Follow-On Offering, provided that the undersigned enters into a new lock-up
letter with the underwriters with respect to the shares of Common Stock that are not being released, upon terms and conditions
reasonably satisfactory to the underwriters but with restrictions that will be no more restrictive than those set forth herein
(other than that the expiration of the new lock-up shall be until the later of the Restricted Period hereunder or 90 days from the
date of such Follow-On Offering). In the event that, as a result of this paragraph, any of the undersigned&rsquo;s shares of Common
Stock are released from the restrictions imposed by this agreement, the Company shall use its commercially reasonable efforts to
notify the undersigned within three business days after the Company has been advised by the Representatives of such release that the
same percentage of shares of Common Stock held by the undersigned has been released, provided that the failure to give such notice
shall not give rise to any claim or liability against the Company or the underwriters. For purposes of this Letter Agreement, an
&ldquo;Exception&rdquo; shall mean any release or waiver (no matter how effectuated, including through an amendment, a new agreement
or otherwise) by the Representatives during the Restricted Period of any prohibition set forth in this Letter Agreement or a similar
letter agreement on the disposition or transfer of Common Stock held by any person or entity that beneficially owns 1% or more of
the outstanding shares of Common Stock (each, a &ldquo;Significant Holder&rdquo;), any director of the Company or any officer of the
Company.</P>
