this Agreement shall be Robert T. Hoffman Sr. (the &ldquo;<U>Initial Designee</U>&rdquo;), whom the Company agrees is a
Qualified Investor Designee.&nbsp; On or prior to the Closing Date, the Company shall take all actions necessary (including,
if necessary, by approving an enlargement of its Board of Directors to create a vacancy thereon) to cause the appointment to
the Board of Directors of the Initial Designee effective as of the Closing Date, and thereafter, for so long as the
Investor&rsquo;s board nomination right under this Section&nbsp;2 continues, the Company will use its commercially
reasonable efforts to cause the election and reelection of such individual to the Board of Directors for so long as he or she
is a Qualified Investor Designee (including recommending that the Company&rsquo;s stockholders vote in favor of the election
of such an individual and otherwise supporting him for election in a manner no less rigorous and favorable than the manner in
which the Company supports its other nominees), provided that if the Investor determines to designate a different individual
(&ldquo;<U>Replacement Designee</U>&rdquo;) as its Investor Designee, and such Replacement Designee is a Qualified Investor
Designee, such obligation shall instead apply to the Replacement Designee.&nbsp; If any Investor Designee vacates the Board
of Directors, the Company shall take all actions necessary to cause the appointment to the Board of Directors of a Qualified
Investor Designee nominated by the Investor to fill the vacancy and thereafter the Company will use its commercially
reasonable efforts to cause the election of such an individual to the Board of Directors, subject to the same conditions and
limitations as set forth in the foregoing sentence.&nbsp; For avoidance of doubt, the Investor shall be limited to only one
designee serving on the Board at any time pursuant to this Section&nbsp;2.&nbsp; Such designee shall be entitled to the same
level of directors&rsquo; and officers&rsquo; indemnity insurance coverage and indemnity and exculpation protection
(including under any indemnification agreement) as the other members of the Board of Directors.&nbsp; For so long as an
Investor Designee serves on the Board of Directors, the Company shall maintain in place directors&rsquo; and officers&rsquo;
indemnity insurance coverage in an amount deemed appropriate by the Board of Directors.&nbsp; Any Investor Designee shall be
subject to the same Company policies and procedures as the other directors on the Board of Directors, including with
respect to conflicts of interest and recusal from deliberations and voting.</P>

on historical fact are &quot;forward-looking statements.&quot; You can find many (but not all) of these statements by looking
