(l)                
The consolidated financial statements filed with the Commission and incorporated by reference into the Registration Statement,
the General Disclosure Package and the Final Prospectus, present fairly, in all material respects, the consolidated financial position
of the Company and its Subsidiaries as of the dates indicated and the results of their operations, changes in stockholders’
equity and cash flows for the periods specified. Such financial statements have been prepared in conformity with International
Financial Reporting Standards (“ IFRS ”) as issued by the International Accounting Standards Board (the “
IASB ”) and Interpretations of the International Financial Reporting Interpretations Committee (“ IFRIC
”), applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes

and the exclusion of certain footnotes. No other financial statements or supporting schedules are required to be included or incorporated
by reference in the Registration Statement, the General Disclosure Package and the Final Prospectus. To the Company’s knowledge,
no person who has been suspended or barred from being associated with a registered public accounting firm, or who has failed to

of, or audited, the financial statements, supporting schedules or other financial data filed with the Commission as a part of the
Registration Statement, the General Disclosure Package and the Final Prospectus.


(m)

in conformity with IFRS as issued by IASB and IFRIC and to maintain accountability for assets; (iii) access to assets is permitted
only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets
is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.


(n)               
The Company has established and maintains disclosure controls and procedures (as defined in Rules 13a-15 and 15d-15
under the Exchange Act), which are designed to ensure that material information relating to the Company, including its consolidated
Subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within
those entities and are effective in all material respects to perform the functions for which they were established. Since the end
of the Company’s most recent audited fiscal year, there has been no material weakness in the Company’s internal control
over financial reporting (whether or not remediated) and no change in the Company’s internal control over financial reporting
that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial
reporting. The Company is not aware of any change in its internal control over financial reporting that has occurred that has materially

(p)               
Each of the Company’s Subsidiaries has been duly incorporated or organized, as the case may be, and is validly existing

laws of the jurisdiction of its incorporation or organization and has the power and authority (corporate or other) to own, lease
and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package
and the Final Prospectus. Each of the Subsidiaries is duly qualified as a foreign corporation, partnership or limited liability
company, as applicable, to transact business and is in good standing in each jurisdiction in which such qualification is required,
whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to be so qualified
or in good standing (where such concept exists) would not, individually or in the aggregate, result in a Material Adverse Change.
All of the issued and outstanding capital stock or other equity or ownership interests of each of the Subsidiaries have been duly
authorized and validly issued, are fully paid and nonassessable and are owned by the Company, directly or through Subsidiaries,
and, except as described in the Registration Statement, the General Disclosure Package and the Final Prospectus, free and clear

are fully paid and nonassessable. Except as described in the Registration Statement, the General Disclosure Package and the Final
Prospectus, none of the outstanding Common Shares was issued in violation of any preemptive rights, rights of first refusal or
other similar rights to subscribe for or purchase securities of the Company. The Common Shares conform to the law of the jurisdiction
of the Company’s incorporation and to any requirements of the Company’s organizational documents. There are no authorized
or outstanding options, warrants, preemptive rights, rights of first refusal or other rights to purchase, or equity or debt securities
convertible into or exchangeable or exercisable for, any capital stock of the Company or any of its Subsidiaries other than those
described in the Registration Statement, the General Disclosure Package and the Final Prospectus. The descriptions of the Company’s
stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth
in the Registration Statement, the General Disclosure Package and the Final Prospectus accurately and fairly presents the information
required to be provided with respect to such plans, arrangements, options and rights.

a party or by which it or any of them may be bound, or to which any of their respective properties or assets are subject (each,
an “ Existing Instrument ”), except (i) for such Defaults as would not be expected, individually or in the aggregate,
to have a Material Adverse Change, and (ii) as disclosed in the Registration Statement, the General Disclosure Package and the

hereby and by the Registration Statement, the General Disclosure Package and the Final Prospectus and the issuance and sale of
the Shares (including the use of proceeds from the sale of the Shares as described in the Registration Statement, the General Disclosure
Package and the Final Prospectus under the caption “Use of Proceeds”) (i) have been duly authorized by all necessary
corporate action and will not result in any violation of the provisions of the articles of association or operating agreement or
similar organizational documents, as applicable, of the Company or any Subsidiary (ii) will not conflict with or constitute
a breach of, or Default or a Debt Repayment Triggering Event (as defined below) under, or result in the creation or imposition
of any lien, charge or encumbrance upon any property or assets of the Company or any of its Subsidiaries pursuant to, or require
the consent of any other party to, any Existing Instrument and (iii) will not result in any violation of any law, administrative
regulation or administrative or court decree applicable to the Company or any of its Subsidiaries except, as to clauses (ii) and
(iii), as would not be expected, individually or in the aggregate, to have a Material Adverse Change. No consent, approval, authorization
or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency, is required
for the Company’s execution, delivery and performance of this Agreement and consummation of the transactions contemplated

by the Company or any of its Subsidiaries.


(t)                
The Company and its Subsidiaries have been and are in compliance with all applicable laws, rules and regulations, except
where failure to be so in compliance would not be expected, individually or in the aggregate, to have a Material Adverse Change.
Each of the Company and its Subsidiaries is not in violation of any provision of its articles of incorporation or by-laws.


(u)               
Except as described in the Registration Statement, the General Disclosure Package and the Final Prospectus, there is no
action, suit, proceeding, inquiry or investigation brought by or before any governmental entity now pending or, to the knowledge
of the Company, threatened, against or affecting the Company or any of its Subsidiaries, which would be expected, individually
or in the aggregate, to have a Material Adverse Change or materially and adversely affect the consummation of the transactions

legal or governmental proceedings to which the Company or any such Subsidiary is a party or of which any of their respective properties
or assets is the subject, including ordinary routine litigation incidental to the business, if determined adversely to the Company,

data and information that are or could reasonably be expected to be material to its business as currently conducted or as currently

of the Company and are enforceable against the Company or such Subsidiary of the Company in accordance with the terms thereof,
except, in each case, where the failure to do so or where such default would not reasonably be expected to have a Material Adverse

of any event or development within the Prospectus Delivery Period as a result of which any Statutory Prospectus, the General Disclosure
Package, any Issuer Free Writing Prospectus, or Final Prospectus, as then amended or supplemented would include any untrue statement

existing when any Statutory Prospectus, the General Disclosure Package, any such Issuer Free Writing Prospectus or Final Prospectus
is delivered to a purchaser, not misleading, and (F) of the receipt by the Company of any notice with respect to any suspension
of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or, to the knowledge of the Company,

with the Representative in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representative

corporation, (y) file a general consent to service of process in any jurisdiction where it is not now so qualified or required
to file such a consent, or (z) subject itself to taxation in any such jurisdiction if it is not otherwise so subject. The Company

of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement
any Statutory Prospectus or the General Disclosure Package in order to make the statements therein, in the light of the circumstances
existing at the time the Statutory Prospectus or General Disclosure Package is delivered to a purchaser, not misleading in any
material respect, or, if it is necessary at any time to amend or supplement any Statutory Prospectus or the General Disclosure
Package to comply with any law, the Company promptly will either (i) prepare and file with the Commission an appropriate amendment
to the Registration Statement or supplement to any Statutory Prospectus or General Disclosure Package, or (ii) prepare and file
with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the Final Prospectus
so that the Final Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered,
be misleading in any material respect, or so that the Final Prospectus will comply with the law.


(g)       The Company will make
generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after
the effective date of the Registration Statement, an earning statement (which need not be audited) in reasonable detail, covering
a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earning statement
shall satisfy the requirements of Section 11(a) of the Act and Rule 158 under the Act and will advise you in writing when such
statement has been so made available.


(h)       Prior to the Closing
Date, the Company will furnish to the Underwriters, as soon as they have been prepared by or are available to the Company (in the
Company’s ordinary course of business), a copy of any unaudited interim financial statements of the Company for any period
subsequent to the period covered by the most recent financial statements appearing in the Registration Statement, the General Disclosure
Package and the Final Prospectus.


(i)       No offering, pledge,
sale, contract to sell, short sale or other disposition of any Common Shares of the Company or other securities convertible into
or exchangeable or exercisable for Common Shares or derivative of Common Shares (or agreement for such) will be made for a period
starting after the date of the Final Prospectus and extending to, but not including, September 24, 2019, directly or indirectly,
by the Company otherwise than hereunder or with the prior written consent of the Representative. Notwithstanding the foregoing,
the Company may (i) sell the Shares to the Underwriters, (ii) issue Common Shares upon exercise, conversion, or exchange of option
or other securities, (iii) file one or more registrations statements registering the secondary sale of Common Shares or securities
convertible into or exchangeable or exercisable for Common Shares, (iv) issue Common Shares, options to purchase Common Shares
or restricted stock units or similar equity securities pursuant to any stock option, stock bonus or other stock plan or arrangement
described in the Registration Statement or Final Prospectus or to be adopted by the Company and its shareholders, (v) issue Common
Shares, options, restricted stock units or similar equity securities to the Company’s directors as compensation for their
services as directors, (vi) enter into agreements providing for the issuance by the Company of Common Shares or any security convertible
into or exchangeable or exercisable for Common Shares in connection with the acquisition by the Company or any of its subsidiaries
of the securities, business, property or other assets of another person or entity (including pursuant to an employee benefit plan
assumed by the Company in connection with such acquisition), and issue any such securities pursuant to any such agreement, and
(vii) enter into agreements providing for the issuance of Common Shares or any security convertible into or exercisable for Common
Shares in connection with joint ventures, commercial relationships, debt financing or other strategic transactions, and issue any
such securities pursuant to any such agreements.


(j)       The Company shall maintain
the listing of the Shares, subject to notice of issuance, on the NYSE American.

(k)       Intentionally omitted.


(l)       The Company shall apply
the net proceeds of its sale of the Shares substantially in the manner described under the caption “Use of Proceeds”
in the Registration Statement, the General Disclosure Package and the Final Prospectus.


(m)       The Company shall not
invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the
Company or any of the Subsidiaries to register as an investment company under the Investment Company Act.


(n)       The Company will maintain
a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Shares.


(o)       The Company will not
take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected
to constitute, the stabilization or manipulation of the price of any securities of the Company.


5.

7.                  
Indemnification.


(a)               
The Company agrees:


(i)       to indemnify and
hold harmless each Underwriter, the directors and officers of each Underwriter and each person, if any, who controls any Underwriter
within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities
to which such Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement
or alleged untrue statement of any material fact contained in the Registration Statement, any Statutory Prospectus, any Issuer
Free Writing Prospectus, the Final Prospectus or any amendment or supplement thereto, (ii) with respect to the Registration Statement
or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading or (iii) with respect to any Statutory Prospectus, any Issuer
Free Writing Prospectus, the Final Prospectus or any amendment or supplement thereto, the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of
the circumstances under which they were made; provided, however, that the Company will not be liable in any such
case to the extent that any such loss, claim, damage or liability (or action or proceeding in respect thereof) arises out of or
is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement,
any Statutory Prospectus, any Issuer Free Writing Prospectus, the Final Prospectus, or such amendment or supplement, in reliance
upon and in conformity with written information furnished to the Company by or through the Representative specifically for use
therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information
described as such in Section 11 hereof; and






    	 	-22-	 



     


    

(ii)       to reimburse each
Underwriter, each Underwriters’ directors and officers, and each such controlling person upon demand for any documented legal
or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating
or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry
related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding.
In the event that it is finally judicially determined that any such Underwriter, any such director or officer or any such controlling
person was not entitled to receive payments for legal and other expenses pursuant to this subparagraph, then the Underwriters will
promptly return all sums that had been advanced pursuant hereto.


(b)               
Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of
its officers who have signed the Registration Statement, and each person, if any, who controls the Company within the meaning of
the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, or controlling
person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement, any Statutory Prospectus, any Issuer Free Writing Prospectus, the Final Prospectus or any amendment
or supplement thereto, (ii) with respect to the Registration Statement or any amendment or supplement thereto, the omission or
alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not
misleading or (iii) with respect to any Statutory Prospectus, any Issuer Free Writing Prospectus, the Final Prospectus or any amendment
or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary
to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse
any legal or other expenses reasonably incurred by the Company or any such director, officer, or controlling person in connection
with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however,
that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission has been made in the Registration Statement, any Statutory Prospectus, any Issuer
Free Writing Prospectus, the Final Prospectus or such amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by or through the Representative specifically for use therein, it being understood and agreed
that the only such information furnished by any Underwriter consists of the information described as such in Section 11
hereof. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.






    	 	-23-	 



     


    

(c)               
In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of
which indemnity may be sought pursuant to this Section 7, such person (the “indemnified party”) shall
promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing.
No indemnification provided for in Section 7(a) or (b) hereof shall be available to any party who shall fail to give
notice as provided in this Section 7(c) if the indemnifying party was materially prejudiced by the failure to give such
notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or
they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 7(a) or
(b) hereof. In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying
party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory
to such indemnified party and shall pay as incurred the reasonable and documented fees and disbursements of such counsel related
to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense.
Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses
of separate counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have
mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties)
include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate
due to actual or potential conflicts of interests between them or (iii) the indemnifying party shall have failed to assume the
defense and employ counsel reasonably acceptable to the indemnified party within a reasonable period of time after notice of commencement
of the action. Such separate counsel shall be designated in writing by you in the case of parties indemnified pursuant to Section
7(a) hereof and by the Company in the case of parties indemnified pursuant to Section 7(b) hereof. The indemnifying
party shall not be liable for any compromise or settlement of any pending or threatened claim, action or proceeding, or for any
consent to the entry of any judgment in any pending or threatened claim, action or proceeding, in each case effected without its
written consent but if settled or compromised with such written consent of the indemnifying party or if there be a final judgment
for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason
of such settlement, compromise or judgment. In addition, the indemnifying party will not, without the prior written consent of
the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action
or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential
party to such claim, action or proceeding) unless such settlement, compromise or consent (i) includes an unconditional release
of each indemnified party from all liability arising out of such claim, action or proceeding 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 any indemnified party. If at any time an indemnified
party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel to which it
is entitled to be reimbursed under this Section 7, such indemnifying party agrees that it shall be liable for any settlement
of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by
such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such
settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed
such indemnified party in accordance with such request and the other provisions of this Section 7 prior to the date of such
settlement.


(d)               
To the extent the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless
an indemnified party under Section 7(a) or (b) hereof in respect of any losses, claims, damages or liabilities (or
actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid
or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence
is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified
party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company
on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions or proceedings 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 shall be deemed to be in the same
proportion as the net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Final Prospectus.
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 on the
one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.






    	 	-24-	 



     


    

(e)               
The Company, and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section
7(e) were determined by pro rata allocation (even if the Underwriters 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 above in this Section 7(e).
The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) referred to above in this Section 7(e) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions
of this Section 7(e), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts
and commissions applicable to the Shares purchased by such Underwriter, and (ii) 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 Underwriters’ obligations in this Section 7(e) to contribute are several in proportion to their
respective underwriting obligations and not joint.


(f)                
In any proceeding relating to the Registration Statement, any Statutory Prospectus, any Issuer Free Writing Prospectus,
the Final Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section
7 hereby consents to the exclusive jurisdiction of (i) the federal courts of the United States of America located in the City
and County of New York, Borough of Manhattan and (ii) the courts of the State of New York located in the City and County of New
York, Borough of Manhattan.


(g)               
The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the
Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made
by or on behalf of any Underwriter, its directors or officers or any person controlling any Underwriter, the Company, its directors
or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any
termination of this Agreement. A successor to any Underwriter, its directors or officers or any person controlling any Underwriter,
or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.


8.                  
Notices.


All notices, consents, approvals, waivers or other communications
(each, a “Notice”) required or permitted hereunder, except as herein otherwise specifically provided, shall
be in writing and shall be (i) delivered personally or by commercial messenger, (ii) sent via a recognized overnight courier service,
(iii) sent by registered or certified mail, postage pre-paid and return receipt requested, or (iv) sent by e-mail or facsimile
transmission, provided confirmation of receipt is received by sender and the original Notice is sent or delivered contemporaneously
by an additional method provided in this Section 8; in each case so long as such Notice is addressed to the intended recipient
thereof as set forth below. Any party may change its address specified below by giving each party Notice of such change in accordance
with this Section 8. Any Notice shall be deemed given upon actual receipt (or refusal of receipt).

(a)               
This Agreement may be terminated by the Representative by notice to the Company (a) at any time prior to the Closing Date
if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement,
the General Disclosure Package and the Final Prospectus, any material adverse change or any development, that individually or in
the aggregate, would reasonably be expected to have a material adverse change in the earnings, business, management, properties,

whether or not arising in the ordinary course of business, except as set forth in the General Disclosure Package and the Final
Prospectus; (ii) any outbreak or escalation of hostilities or declaration of war or national emergency or other national or international
calamity or crisis (including, without limitation, an act of terrorism) or change in economic or political conditions if the effect

would, in your judgment, materially impair the investment quality of the Shares; (iii) suspension of trading in securities generally
on the New York Stock Exchange or the NASDAQ Global Market or limitation on prices (other than limitations on hours or numbers
of days of trading) for securities on any such exchange; (iv) the enactment, publication, decree or other promulgation of any statute,
regulation, rule or order of any court or other governmental authority which in your opinion materially and adversely affects or
may materially and adversely affect the business or operations of the Company; (v) the declaration of a banking moratorium by the
United States or New York State authorities; (vi) any downgrading, or placement on any watch list for possible downgrading, in

10.              
Successors.


This Agreement has been and is made solely for the benefit of the
Underwriters, the Company and their respective successors, executors, administrators, heirs and assigns, and the officers, directors
and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any
of the Shares from any Underwriter shall be deemed a successor or assign merely because of such purchase.


11.              
Information Provided by Underwriters.



The Company and the Underwriters acknowledge
and agree that the only information furnished or to be furnished by any Underwriter to the Company for inclusion in the Registration
Statement, any Statutory Prospectus, any Issuer Free Writing Prospectus, or the Final Prospectus consists of the information set
forth in the eighth paragraph under the caption “Underwriting” in the Final Prospectus.


 





12.              
Miscellaneous.


The reimbursement, indemnification and contribution agreements contained
in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless

or by or on behalf of the Company or its directors or officers, and (c) delivery of and payment for the Shares under this Agreement.


The Company acknowledges and agrees that each Underwriter in providing
investment banking services to the Company in connection with the offering, including in acting pursuant to the terms of this Agreement,
has acted and is acting as an independent contractor and not as a fiduciary and the Company and does not intend such Underwriter
to act in any capacity other than as an independent contractor, including as a fiduciary or in any other position of higher trust.
Additionally, neither the Representative nor any other Underwriter is advising the Company or any other person as to any legal,
tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with their own advisors concerning
such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated
hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters
of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for
the benefit of the Underwriters and shall not be on behalf of the Company.


This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute one and the same instrument.


This Agreement shall be governed by, and construed in accordance
with, the law of the State of New York, including, without limitation, Section 5-1401 of the New York General Obligations Law.

action, claim, suit or proceeding with respect to your engagement as underwriter or your role in connection herewith.


If the foregoing is in accordance with your understanding of our
agreement, please sign and return to us the enclosed duplicates hereof, whereupon it will become a binding agreement among the
Company and the several Underwriters in accordance with its terms.
