Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the
question of whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication
of such issue.</FONT></P>

Prospectus, the Prospectus or any Issuer Free Writing Prospectus (as from time to time each may be amended and supplemented);
(ii) any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing

untrue statement or omission made in the Pricing Disclosure Package, the indemnity agreement contained in this Section 5.1.1 shall
not inure to the benefit of any Underwriter Indemnified Party to the extent that any loss, liability, claim, damage or expense
of such Underwriter Indemnified Party results from the fact that a copy of the Prospectus was not given or sent to the person
asserting any such loss, liability, claim or damage at or prior to the written confirmation of sale of the Public Securities to
such person as required by the Securities Act and the Securities Act Regulations, and if the untrue statement or omission has
been corrected in the Prospectus, unless such failure to deliver the Prospectus was a result of non-compliance by the Company
with its obligations under Section 3.3 hereof.</FONT></P>

<U>Procedure</U>. If any action is brought against an Underwriter Indemnified Party in respect of which indemnity may be sought
against the Company pursuant to Section 5.1.1, such Underwriter Indemnified Party shall promptly notify the Company in writing
of the institution of such action and the Company shall be entitled to participate therein and, to the extent that it wishes,
jointly with any other similarly notified indemnifying party, to assume the defense of such action, including the employment and
fees of counsel (subject to the reasonable approval of such Underwriter Indemnified Party) and payment of actual expenses. Such
Underwriter Indemnified Party shall have the right to employ its or their own counsel in any such case, but the fees and expenses
of such counsel shall be at the expense of such Underwriter Indemnified Party unless (i) the employment of such counsel at the
expense of the Company shall have been authorized in writing by the Company in connection with the defense of such action, or
(ii) the Company shall not have employed counsel to have charge of the defense of such action, or (iii) such indemnified party
or parties shall have been advised by its counsel that there may be defenses available to it or them which are different from
or additional to those available to the Company (in which case the Company shall not have the right to direct the defense of such
action on behalf of the indemnified party or parties), in any of which events the reasonable fees and expenses of not more than
one additional firm of attorneys selected by the Underwriter Indemnified Parties who are party to such action (in addition to
local counsel) shall be borne by the Company. Notwithstanding anything to the contrary contained herein, if any Underwriter Indemnified
Party shall assume the defense of such action as provided above, the Company shall have the right to approve the terms of any
settlement of such action, which approval shall not be unreasonably withheld.</FONT></P>

<U>Indemnification of the Company</U>. Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company,
its directors, its officers who signed the Registration Statement and persons who control the Company within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, damage and expense described
in the foregoing indemnity from the Company to the several Underwriters, as incurred, but only with respect to such losses, liabilities,
claims, damages and expenses (or actions in respect thereof) which arise out of or are based upon untrue statements or omissions
made in the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package or Prospectus or any amendment
or supplement thereto or in any application, in reliance upon, and in strict conformity with, the Underwriters&rsquo; Information.
In case any action shall be brought against the Company or any other person so indemnified based on any Preliminary Prospectus,
the Registration Statement, the Pricing Disclosure Package or Prospectus or any amendment or supplement thereto or any application,
and in respect of which indemnity may be sought against any Underwriter, such Underwriter shall have the rights and duties given
to the Company, and the Company and each other person so indemnified shall have the rights and duties given to the several Underwriters
by the provisions of Section 5.1.2. The Company agrees promptly to notify the Representative of the commencement of any litigation
or proceedings against the Company or any of its officers, directors or any person, if any, who controls the Company within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, in connection with the issuance and sale of the
Public Securities or in connection with the Registration Statement, the Pricing Disclosure Package, the Prospectus or any Issuer
Free Writing Prospectus.</FONT></P>

<U>Contribution Rights</U>. If the indemnification provided for in this Section 5 shall for any reason be unavailable to or insufficient
to hold harmless an indemnified party under Section 5.1 or 5.2 in respect of any loss, claim, damage or liability, or any action
in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute
to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect
thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, on the one hand,
and each of the Underwriters, on the other hand, from the Offering, or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in
clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, with respect
to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as
any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters,
on the other, with respect to such Offering shall be deemed to be in the same proportion as the total proceeds from the Offering
purchased under this Agreement (before deducting expenses) received by the Company bear to the total underwriting discount and
commissions received by the Underwriters in connection with the Offering, in each case as set forth in the table on the cover
page of the Prospectus. The relative fault of the Company, on the one hand, and the Underwriters, on the other, 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, on the one hand, or the Underwriters, on the
other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such
untrue statement, omission, act or failure to act; provided that the parties hereto agree that the written information furnished
to the Company through the Representative by or on behalf of any Underwriter for use in any Preliminary Prospectus, any Registration
Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Underwriters&rsquo; Information.
The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 5.3.1
were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable
considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage,
expense, liability, action, investigation or proceeding referred to above in this Section 5.3.1 shall be deemed to include, for
purposes of this Section 5.3.1, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating,
preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection
with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. Notwithstanding the provisions of
this Section 5.3.1 no Underwriter shall be required to contribute any amount in excess of the total discount and commission received
by such Underwriter in connection with the Offering less the amount of any damages which such Underwriter has otherwise paid or
becomes liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or
failure to act or alleged failure to act. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.</FONT></P>

<U>Contribution Procedure</U>. Within fifteen (15) days after receipt by any party to this Agreement (or its representative) of
notice of the commencement of any action, suit or proceeding, such party will, if a claim for contribution in respect thereof
is to be made against another party (&ldquo;contributing party&rdquo;), notify the contributing party of the commencement thereof,
but the failure to so notify the contributing party will not relieve it from any liability which it may have to any other party
other than for contribution hereunder. In case any such action, suit or proceeding is brought against any party, and such party
notifies a contributing party or its representative of the commencement thereof within the aforesaid 15 days, the contributing
party will be entitled to participate therein with the notifying party and any other contributing party similarly notified. Any
such contributing party shall not be liable to any party seeking contribution on account of any settlement of any claim, action
or proceeding affected by such party seeking contribution without the written consent of such contributing party. The contribution
provisions contained in this Section 5.3.2 are intended to supersede, to the extent permitted by law, any right to contribution
under the Securities Act, the Exchange Act or otherwise available. The Underwriters&rsquo; obligations to contribute as provided
in this Section 5.3 are several and in proportion to their respective underwriting obligation, and not joint.</FONT></P>
