necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it
is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company
will promptly notify the Representative of such event so that any use of the General Disclosure Package may cease until it is amended
or supplemented and will promptly prepare and file with the Commission and furnish, at its own expense, to the Placement Agents
and the dealers and any other dealers in such quantities as the Representative may reasonably request, an amendment or supplement
which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representative&rsquo;s

earnings results during the 16-day period beginning on the last day of the initial Lock-Up Period, then in each case the Lock-Up
Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the
occurrence of the materials news or material event, as applicable, unless the Representative waives, in writing, such extension.
The Company will provide the Representative with notice of any announcement described in clause (2) of the preceding sentence that
gives rise to an extension of the Lock-Up Period. <FONT STYLE="font: 10pt Times New Roman, Times, Serif">Notwithstanding the foregoing,
during the Lock-Up Period, the Company may close any offering or offerings of its securities</FONT> (the &ldquo;<B>Subsequent Offering</B>&rdquo;)

</FONT><I>Actions against Parties; Notification</I>. Promptly after receipt by an indemnified party under this Section of notice
of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying
party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the
indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent
that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided
further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified
party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it
notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and,
to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to
the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other
expenses subsequently incurred by such indemnified party in connection with the defense thereof except as set forth below. Notwithstanding
the indemnifying party&rsquo;s election to appoint counsel to represent the indemnified party in an action, the indemnified party
shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable
fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified
party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such
action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those
available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified
party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying
party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. No indemnifying
party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action
in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on
any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability
or a failure to act by or on behalf of an indemnified party.</P>

</FONT><I>Contribution</I>. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless
an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable
by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above
in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Placement
Agents on the other from the offering of the Securities; provided, however, that in no case shall any Placement Agent be responsible
for any contribution in an amount in excess of the placement agent fees and commissions applicable to the Securities purchased
by the Purchasers hereunder. If the allocation provided above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to above but also the relative fault of the Company on the one hand and the
Placement Agents on the other in connection with the statements or omissions which resulted in such losses, claims, damages or
liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand
and the Placement Agents on the other shall be deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Company bear to the total placement agent fees and commissions received by the Placement
Agents. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company
or the Placement Agents and the parties&rsquo; relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or
liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this
subsection (d). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled
to contribution from any person who was not guilty of such fraudulent misrepresentation. The Placement Agents&rsquo; obligations
in this subsection (d) to contribute are several in proportion to their respective placement agent obligations and not joint. The
Company and the Placement Agents agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were
determined by pro rata allocation (even if the Placement Agents were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations referred to in this Section 8(d).</P>
