ARTICLE II.

PURCHASE AND SALE

 

2.1 Closing.
On the Closing Date, upon the terms and subject to the conditions set forth herein, substantially concurrent with the execution and delivery
of this Agreement by the parties hereto, the Company agrees to sell, and the Purchasers, severally and not jointly, agree to purchase,
up to an aggregate of approximately $4.4 million of Shares and Warrants; provided, however, that, to the extent a Purchaser determines,
in its sole discretion, that such Purchaser (together with such Purchaser’s Affiliates) would beneficially own in excess of the
Beneficial Ownership Limitation, or as such Purchaser may otherwise choose, in lieu of purchasing Shares such Purchaser may elect to purchase
registered Pre-Funded Warrants in lieu of Shares in such manner to result in the same aggregate purchase price being paid by such Purchaser
to the Company. The “Beneficial Ownership Limitation” shall be 4.99% (or, at the election of the Purchaser at the Closing,
9.99%) of the number of the Common Shares outstanding immediately after giving effect to the issuance of the Securities on the Closing
Date. Each Purchaser’s Subscription Amount as set forth on the signature page hereto executed by such Purchaser shall be made available
for “Delivery Versus Payment” settlement with the Company or its designee. The Company shall deliver to each Purchaser its
respective Shares (or Pre-Funded Warrants) and a Warrant as determined pursuant to Section 2.2(a), and the Company and each Purchaser
shall deliver the other items set forth in Section 2.2 deliverable at the Closing. Upon satisfaction of the covenants and conditions set
forth in Sections 2.2 and 2.3, the Closing shall occur remotely via the exchange of documents and signatures or such other location as
the parties shall mutually agree. Notwithstanding anything herein to the contrary, if at any time on or after the time of execution of
this Agreement by the Company and an applicable Purchaser, through, and including the time immediately prior to the Closing (the “Pre-Settlement
Period”), such Purchaser sells to any Person all, or any portion, of the Shares to be issued hereunder to such Purchaser at
the Closing (collectively, the “Pre-Settlement Shares”), such Purchaser shall, automatically hereunder (without any
additional required actions by such Purchaser or the Company), be deemed to be unconditionally bound to purchase, such Pre-Settlement
Shares to such Purchaser at the Closing; provided, that the Company shall not be required to deliver any Pre-Settlement Shares to such
Purchaser prior to the Company’s receipt of the purchase price of such Pre-Settlement Shares hereunder; and provided further that
the Company hereby acknowledges and agrees that the forgoing shall not constitute a representation or covenant by such Purchaser as to
whether or not during the Pre-Settlement Period such Purchaser shall sell any Common Shares to any Person and that any such decision to
sell any Common Shares by such Purchaser shall solely be made at the time such Purchaser elects to effect any such sale, if any. Unless
otherwise directed by the Placement Agent, settlement of the Shares shall occur via “Delivery Versus Payment” (“DVP”)
(i.e., on the Closing Date, the Company shall issue the Shares registered in the Purchasers’ names and addresses and released by
the Transfer Agent directly to the account(s) at the Placement Agent identified by each Purchaser; upon receipt of such Shares, the Placement
Agent shall promptly electronically deliver such Shares to the applicable Purchaser, and payment therefor shall be made by the Placement
Agent (or its clearing firm) by wire transfer to the Company). Notwithstanding anything to the contrary herein and the Purchaser’s
Subscription Amount set forth on the signature pages attached hereto, the number of Shares purchased by a Purchaser (and its Affiliates)
hereunder shall not, when aggregated with all other Common Shares owned by such Purchaser (and its Affiliates) at such time, result in
such Purchaser beneficially owning (as determined in accordance with Section 13(d) of the Exchange Act) in excess of 9.99% of the then
issued and outstanding Common Shares outstanding at the Closing (the “Beneficial Ownership Maximum”), and such Purchaser’s
Subscription Amount, to the extent it would otherwise exceed the Beneficial Ownership Maximum immediately prior to the Closing, shall
be conditioned upon the issuance of Shares at the Closing to the other Purchasers signatory hereto. To the extent that a Purchaser’s
beneficial ownership of the Shares would otherwise be deemed to exceed the Beneficial Ownership Maximum, such Purchaser’s Subscription
Amount shall automatically be reduced as necessary in order to comply with this paragraph. Notwithstanding the foregoing, with respect
to any Notice(s) of Exercise (as defined in the Pre-Funded Warrants) delivered on or prior to 4:00 p.m. (New York City time) on the Trading
Day prior to the Closing Date, which may be delivered at any time after the time of execution of this Agreement, the Company agrees to
deliver the applicable Pre-Funded Warrant Shares subject to such notice(s) by 4:00 p.m. (New York City time) on the Closing Date and the
Closing Date shall be the Warrant Share Delivery Date (as defined in the Pre-Funded Warrants) for purposes hereunder.

All of the direct and indirect subsidiaries of the Company are set forth on Schedule 3.1(a). The Company owns, directly or indirectly,
all of the capital stock or other equity interests of each Subsidiary free and clear of any Liens, and all of the issued and outstanding

or charter documents. Each of the Company and the Subsidiaries is duly qualified to conduct business and is in good standing as a foreign

a change in the market price of trading volume of the Common Shares alone shall not be deemed, in and of itself, to constitute a Material
Adverse Effect. To the knowledge of the Company, no Proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing
or seeking to revoke, limit or curtail such power and authority or qualification.

 

(c) Authorization;

enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive

is a party, the issuance and sale of the Securities and the consummation by it of the transactions contemplated hereby and thereby do
not and will not (i) conflict with or violate any provision of the Company’s or any Subsidiary’s certificate or articles of
incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with

or asset of the Company or a Subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not
have or reasonably be expected to result in a Material Adverse Effect.

employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any
of the foregoing matters. The Company and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and
regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the
failure to be in compliance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(iii) are in compliance with all terms and conditions of any such permit, license or approval where in each clause (i), (ii) and (iii),

(n) Regulatory
Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal,
state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports, except
where the failure to possess such permits could not reasonably be expected to result in a Material Adverse Effect (“Material
Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation or modification
of any Material Permit.

rights of any Person, except as could not have or reasonably be expected to not have a Material Adverse Effect. To the knowledge of the
Company, all such Intellectual Property Rights are enforceable and there is no existing infringement by another Person of any of the Intellectual
Property Rights. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and
value of all of their intellectual properties, except where failure to do so could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

a significant increase in cost.

(s) Sarbanes-Oxley;
Internal Accounting Controls. The Company and the Subsidiaries are in compliance with any and all applicable requirements of the Sarbanes-Oxley
Act of 2002 that are effective as of the date hereof, and any and all applicable rules and regulations promulgated by the Commission thereunder
that are effective as of the date hereof and as of the Closing Date. The Company and the Subsidiaries maintain a system of internal accounting

GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific

established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and the Subsidiaries
and designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports
it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s
rules and forms. The Company’s certifying officers have evaluated the effectiveness of the disclosure controls and procedures of
the Company and the Subsidiaries as of the end of the period covered by the most recently filed Annual Report on Form 20-F under the Exchange
Act (such date, the “Evaluation Date”). The Company presented in its most recently filed Annual Report on Form 20-F
under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based
on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the internal control over financial

cause the Company or any Subsidiary to effect the registration under the Securities Act of any securities of the Company or any Subsidiary.

 

(w) Listing
and Maintenance Requirements. The Common Shares are registered pursuant to Section 12(b) or 12(g) of the Exchange Act, and the Company
has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration of the Common
Shares under the Exchange Act nor has the Company received any notification that the Commission is contemplating terminating such registration.
Other than as described in the SEC Reports, the Company has not, in the 12 months preceding the date hereof, received notice from any
Trading Market on which the Common Shares are or have been listed or quoted to the effect that the Company is not in compliance with the
listing or maintenance requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable
future continue to be, in compliance with all such listing and maintenance requirements. The Common Shares are currently eligible for
electronic transfer through the Depository Trust Company or another established clearing corporation and the Company is current in payment
of the fees to the Depository Trust Company (or such other established clearing corporation) in connection with such electronic transfer.

 

    18

     

    

 

(x) Application
of Takeover Protections. The Company and the Board of Directors have taken all necessary action, if any, in order to render inapplicable
any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar
anti-takeover provision under the Company’s certificate of incorporation (or similar charter documents) or the laws of its state
of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their obligations
or exercising their rights under the Transaction Documents, including without limitation as a result of the Company’s issuance of
the Securities and the Purchasers’ ownership of the Securities.

 

(y) Disclosure.
Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company confirms
that neither it nor any other Person acting on its behalf has provided any of the Purchasers or their agents or counsel with any information
that it believes constitutes or might constitute material, non-public information which is not otherwise disclosed in the Prospectus Supplement.
The Company understands and confirms that the Purchasers will rely on the foregoing representation in effecting transactions in securities
of the Company. All of the disclosure furnished by or on behalf of the Company to the Purchasers regarding the Company and its Subsidiaries,
their respective businesses and the transactions contemplated hereby, including the Disclosure Schedules to this Agreement, is true and
correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the
statements made therein, in the light of the circumstances under which they were made, not misleading. The press releases disseminated
by the Company during the twelve months preceding the date of this Agreement taken as a whole do not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in
the light of the circumstances under which they were made and when made, not misleading. The Company acknowledges and agrees that no Purchaser
makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically
set forth in Section 3.2 hereof.

 

(z) No
Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2, neither
the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers or sales
of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be
integrated with prior offerings by the Company for purposes of (i) the Securities Act which would require the registration of the Warrants
or Warrant Shares under the Securities Act, or (ii) any applicable shareholder approval provisions of any Trading Market on which any
of the securities of the Company are listed or designated.

 

    19

     

    

 

(aa) Solvency.
Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the Company
of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value of the Company’s assets exceeds the amount
that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent
liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as
now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the
business conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current
cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into
account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts
are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account
the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances
which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction
within one year from the Closing Date. Schedule 3.1(aa) sets forth as of the date hereof all outstanding secured and unsecured
Indebtedness of the Company or any Subsidiary, or for which the Company or any Subsidiary has commitments. For the purposes of this Agreement,
“Indebtedness” means (x) any liabilities for borrowed money or amounts owed in excess of $50,000 (other than trade
accounts payable incurred in the ordinary course of business), (y) all guaranties, endorsements and other contingent obligations in respect
of indebtedness of others, whether or not the same are or should be reflected in the Company’s consolidated balance sheet (or the
notes thereto), except guaranties by endorsement of negotiable instruments for deposit or collection or similar transactions in the ordinary
course of business; and (z) the present value of any lease payments in excess of $50,000 due under leases required to be capitalized in
accordance with GAAP. Neither the Company nor any Subsidiary is in default with respect to any Indebtedness.

 

(bb) Tax Status.
Except for matters that would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect,
the Company and its Subsidiaries each (i) has made or filed all federal, state and local income and all foreign income and franchise tax
returns, reports and declarations required by any jurisdiction to which it is subject, (ii) has paid all taxes and other governmental
assessments and charges that are material in amount, shown or determined to be due on such returns, reports and declarations and (iii)
has set aside on its books provision reasonably adequate for the payment of all material taxes for periods subsequent to the periods to
which such returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority

a security interest in some or all of the Warrants or Warrant Shares to a financial institution that is an “accredited investor”
as defined in Rule 501(a) under the Securities Act and, if required under the terms of such arrangement, such Purchaser may transfer pledged
or secured Warrants or Warrant Shares to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of
the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith.
Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver
such reasonable documentation as a pledgee or secured party of Warrants and Warrant Shares may reasonably request in connection with a
pledge or transfer of the Warrants or Warrant Shares.

 

(c) Certificates
evidencing the Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while a registration
statement covering the resale of such security is effective under the Securities Act, or (ii) following any sale of such Warrant Shares
pursuant to Rule 144, or (iii) if such Warrant Shares are eligible for sale under Rule 144, or (iv) if such legend is not required under
applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission).
The Company shall cause its counsel to issue a legal opinion to the Transfer Agent or the Purchaser promptly if required by the Transfer
Agent to effect the removal of the legend hereunder, or if requested by a Purchaser, respectively. If all or any portion of a Warrant
is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or if such Warrant
Shares may be sold under Rule 144 or if such legend is not otherwise required under applicable requirements of the Securities Act (including
judicial interpretations and pronouncements issued by the staff of the Commission) then such Warrant Shares shall be issued free of all
legends. The Company agrees that following such time as such legend is no longer required under this Section 4.1(c), the Company will,
no later than the later of (i) five Business Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined
below) following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Warrant Shares, as applicable,
issued with a restrictive legend (such date, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser
a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its
records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4. Warrant Shares
subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by crediting the account of the Purchaser’s
prime broker with the Depository Trust Company System as directed by such Purchaser. As used herein, “Standard Settlement Period”
means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect
to the Common Shares as in effect on the date of delivery of a certificate representing Warrant Shares issued with a restrictive legend.

 

(d) In
addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial liquidated
damages and not as a penalty, for each $1,000 of Warrant Shares (based on the VWAP of the Common Shares on the date such Securities are
submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.1(c), $10 per Trading Day (increasing
to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each Trading Day after the Legend Removal Date
until such certificate is delivered without a legend and (ii) if the Company fails to (a) issue and deliver (or cause to be delivered)
to a Purchaser by the Legend Removal Date a certificate representing the Securities so delivered to the Company by such Purchaser that
is free from all restrictive and other legends and (b) if after the Legend Removal Date such Purchaser purchases (in an open market transaction
or otherwise) Common Shares to deliver in satisfaction of a sale by such Purchaser of all or any portion of the number of Common Shares,
or a sale of a number of Common Shares equal to all or any portion of the number of Common Shares, that such Purchaser anticipated receiving
from the Company without any restrictive legend, then an amount equal to the excess of such Purchaser’s total purchase price (including
brokerage commissions and other out-of-pocket expenses, if any) for the Common Shares so purchased (including brokerage commissions and
other out-of-pocket expenses, if any) (the “Buy-In Price”) over the product of (A) such number of Warrant Shares
that the Company was required to deliver to such Purchaser by the Legend Removal Date multiplied by (B) the lowest closing sale price
of the Common Shares on any Trading Day during the period commencing on the date of the delivery by such Purchaser to the Company of the
applicable Warrant Shares (as the case may be) and ending on the date of such delivery and payment under this Section 4.1(d).

 

    31

     

    

 

(e) The
Shares, Pre-Funded Warrants and Pre-Funded Warrant Shares, upon exercise, shall be issued free of legends.

 

4.2 Furnishing
of Information.

 

(a) Until
the earliest of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired, the Company covenants to timely file
(or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company
after the date hereof pursuant to the Exchange Act even if the Company is not then subject to the reporting requirements of the Exchange
Act.

 

(b) At
any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of the Warrant
Shares may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without restriction or
limitation pursuant to Rule 144, if the Company (i) shall fail for any reason to satisfy the current public information requirement under
Rule 144(c) or (ii) has ever been an issuer described in Rule 144(i)(1)(i) or becomes an issuer in the future, and the Company shall fail
to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”) then, in addition to such Purchaser’s
other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason
of any such delay in or reduction of its ability to sell the Warrant Shares, an amount in cash equal to two percent (2.0%) of the aggregate
Exercise Price of such Purchaser’s Warrants on the day of a Public Information Failure and on every thirtieth (30th)
day (pro rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information Failure
is cured and (b) such time that such public information is no longer required  for the Purchasers to transfer the Warrant Shares
pursuant to Rule 144.  The payments to which a Purchaser shall be entitled pursuant to this Section 4.2(b) are referred to herein
as “Public Information Failure Payments.”  Public Information Failure Payments shall be paid on the earlier of
(i) the last day of the calendar month during which such Public Information Failure Payments are incurred and (ii) the third (3rd)
Business Day after the event or failure giving rise to the Public Information Failure Payments is cured.  In the event the Company
fails to make Public Information Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at
the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit such Purchaser’s right to
pursue actual damages for the Public Information Failure, and such Purchaser shall have the right to pursue all remedies available to
it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

 

    32

     

    

 

4.3 Integration.
The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section
2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Warrants or Warrant Shares or that would be integrated with the offer or sale of the Securities
for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior to the closing of
such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

 

4.4 Securities
Laws Disclosure; Publicity. The Company shall (a) by the Disclosure Time, issue a press release disclosing the material terms of the
transactions contemplated hereby, and (b) file a Report on Form 6-K, including the Transaction Documents as exhibits thereto, with the
Commission within the time required by the Exchange Act. From and after the issuance of such press release, the Company represents to
the Purchasers that it shall have publicly disclosed all material, non-public information delivered to any of the Purchasers by the Company
or any of its Subsidiaries, or any of their respective officers, directors, employees, Affiliates or agents, including, without limitation,
the Placement Agent, in connection with the transactions contemplated by the Transaction Documents. In addition, effective upon the issuance
of such press release, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement,
whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, employees, Affiliates
or agents, including, without limitation, the Placement Agent, on the one hand, and any of the Purchasers or any of their Affiliates on
the other hand, shall terminate and be no further force or effect. The Company understands and confirms that each Purchaser shall be relying
on the foregoing covenant in effecting transactions in securities of the Company. The Company and each Purchaser shall consult with each
other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor any Purchaser
shall issue any such press release nor otherwise make any such public statement without the prior consent of the Company, with respect
to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release of the Company,
which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case the disclosing
party shall promptly provide the other party with prior notice of such public statement or communication. Notwithstanding the foregoing,
the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission
or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (a) as required by federal securities
law in connection with the filing of final Transaction Documents with the Commission and (b) to the extent such disclosure is required
by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted
under this clause (b) and reasonably cooperate with such Purchaser regarding such disclosure.

 

    33

     

    

 

4.5 Shareholder
Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Purchaser
is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including any distribution
under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company, or that any Purchaser
could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents
or under any other agreement between the Company and the Purchasers.

 

4.6 Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents,
which shall be disclosed pursuant to Section 4.4, the Company covenants and agrees that neither it, nor any other Person acting on its
behalf will provide any Purchaser or its agents or counsel with any information that constitutes, or the Company reasonably believes constitutes,
material non-public information, unless prior thereto such Purchaser shall have consented in writing to the receipt of such information
and agreed in writing with the Company to keep such information confidential. The Company understands and confirms that each Purchaser
shall be relying on the foregoing covenant in effecting transactions in securities of the Company. To the extent that the Company, any
of its Subsidiaries, or any of their respective officers, directors, agents, employees or Affiliates delivers any material, non-public
information to a Purchaser without such Purchaser’s consent, the Company hereby covenants and agrees that such Purchaser shall not
have any duty of confidentiality to the Company, any of its Subsidiaries, or any of their respective officers, directors, employees, Affiliates
or agents, including, without limitation, the Placement Agent, or a duty to the Company, any of its Subsidiaries or any of their respective
officers, directors, employees, Affiliates or agents, including, without limitation, the Placement Agent, not to trade on the basis of,
such material, non-public information, provided that the Purchaser shall remain subject to applicable law. To the extent that any notice
provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding the Company or any
Subsidiaries, the Company shall simultaneously with the delivery of such notice file such notice with the Commission pursuant to a Report
on Form 6-K. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions
in securities of the Company.

 

4.7 Use
of Proceeds. Except as set forth on Schedule 4.7 attached hereto, the Company shall use the net proceeds from the sale of the
Securities hereunder for working capital purposes and shall not use such proceeds: (a) for the satisfaction of any portion of the Company’s
debt (other than payment of trade payables in the ordinary course of the Company’s business and prior practices), (b) for the redemption
of any Common Shares or Common Share Equivalents, (c) for the settlement of any outstanding litigation or (d) in violation of FCPA or
OFAC regulations.

 

    34

     

    

 

4.8 Indemnification
of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold each Purchaser and its directors,
officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person
holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners
or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such
title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any and all losses,
liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court
costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of
or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement
or in the other Transaction Documents or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their
respective Affiliates, by any stockholder of the Company who is not an Affiliate of such Purchaser Party, with respect to any of the transactions
contemplated by the Transaction Documents (unless such action is solely based upon a material breach of such Purchaser Party’s representations,
warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such
stockholder or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party which
is finally judicially determined to constitute fraud, gross negligence or willful misconduct) or (c) in connection with any registration
statement of the Company providing for the resale by the Purchasers of the Warrant Shares issued and issuable upon exercise of the Warrants,
the Company will indemnify each Purchaser Party, to the fullest extent permitted by applicable law, from and against any and all losses,
claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses, as incurred, arising
out of or relating to (i) any untrue or alleged untrue statement of a material fact contained in such registration statement, any prospectus
or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to
any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the
case of any prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading, except to
the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding such Purchaser
Party furnished in writing to the Company by such Purchaser Party expressly for use therein, or (ii) any violation or alleged violation
by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder in connection
therewith. If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement,
such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof
with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of
such Purchaser Party except to the extent that (x) the employment thereof has been specifically authorized by the Company in writing,
(y) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (z) in such action there
is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position
of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such
separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (1) for any settlement by a Purchaser Party
effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (2) to the extent,
but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations,
warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification
required by this Section 4.8 shall be made by periodic payments of the amount thereof during the course of the investigation or defense,
as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to any cause of action
or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to pursuant to law.

 

4.9 Reservation
of Common Shares. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available at
all times, free of preemptive rights, a sufficient number of Common Shares for the purpose of enabling the Company to issue Shares pursuant
to this Agreement, Pre-Funded Warrant Shares pursuant to any exercise of the Pre-Funded Warrants and Warrant Shares pursuant to any exercise
of the Warrants.

 

    35

     

    

 

4.10 Listing
of Common Shares. The Company hereby agrees to use best efforts to maintain the listing or quotation of the Common Shares on the Trading
Market on which it is currently listed, and prior to the Closing, the Company shall have applied to list or quote all of the Shares, Pre-Funded
Warrant Shares and Warrant Shares on such Trading Market and concurrently with the Closing, the Company shall have secured the listing
of all of the Shares, Pre-Funded Warrant Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company
applies to have the Common Shares traded on any other Trading Market, it will then include in such application all of the Shares, Pre-Funded
Warrant Shares and Warrant Shares, and will take such other action as is necessary to cause all of the Shares, Pre-Funded Warrant Shares
and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible. The Company will then take all action
reasonably necessary to continue the listing and trading of its Common Shares on a Trading Market and will comply in all material respects
with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market. The Company agrees to
maintain the eligibility of the Common Shares for electronic transfer through the Depository Trust Company or another established clearing
corporation, including, without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing
corporation in connection with such electronic transfer.

 

4.11 [RESERVED.]

 

4.12 Subsequent
Equity Sales.

 

(a) From
the date hereof until sixty (60) days after the Closing Date, neither the Company nor any Subsidiary shall (i) issue, enter into any agreement
to issue or announce the issuance or proposed issuance of any Common Shares or Common Share Equivalents or (ii) file a registration statement
or any amendment or supplement thereto, other than the Prospectus Supplement and the registration statement contemplated pursuant to Section
4.17.

 

(b) From
the date hereof until sixty (60) days after the Closing Date, the Company shall be prohibited from effecting or entering into an agreement
to effect any issuance by the Company or any of its Subsidiaries of Common Shares or Common Share Equivalents (or a combination of units
thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company
(i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to
receive additional Common Shares either (A) at a conversion price, exercise price or exchange rate or other price that is based upon and/or
varies with the trading prices of or quotations for the Common Shares at any time after the initial issuance of such debt or equity securities,
or (B) with a conversion, exercise or exchange price that is subject to being reset at some future date after the initial issuance of
such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of
the Company or the market for the Common Shares or (ii) enters into, or effects a transaction under, any agreement, including, but not
limited to, an equity line of credit, whereby the Company may issue securities at a future determined price. Any Purchaser shall be entitled
to obtain injunctive relief against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect
damages.

 

(c) Notwithstanding
the foregoing, this Section 4.12 shall not apply in respect of an Exempt Issuance, except that no Variable Rate Transaction shall be an
Exempt Issuance.

 

    36

     

    

 

4.13 Equal
Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or paid to any
Person to amend or consent to a waiver or modification of any provision of the Transaction Documents unless the same consideration is
also offered to all of the parties to the Transaction Documents. For clarification purposes, this provision constitutes a separate right
granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers
as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition
or voting of Securities or otherwise.

 

4.14 Certain
Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither it nor
any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales
of any of the Company’s securities during the period commencing with the execution of this Agreement and ending at such time that
the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section
4.4.  Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated
by this Agreement are publicly disclosed by the Company pursuant to the initial press release as described in Section 4.4, such Purchaser
will maintain the confidentiality of the existence and terms of this transaction and the information included in the Disclosure Schedules. 
Notwithstanding the foregoing and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges
and agrees that (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions
in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced pursuant
to the initial press release as described in Section 4.4, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions
in any securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated
by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4 and (iii) no Purchaser
shall have any duty of confidentiality or duty not to trade in the securities of the Company to the Company or its Subsidiaries after
the issuance of the initial press release as described in Section 4.4.  Notwithstanding the foregoing, in the case of a Purchaser
that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets
and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions
of such Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio
manager that made the investment decision to purchase the Securities covered by this Agreement.

 

    37

     

    

 

4.15 Exercise
Procedures. The form of Notice of Exercise included in the Warrants and Pre-Funded Warrants set forth the totality of the procedures
required of the Purchasers in order to exercise the Warrants and Pre-Funded Warrants. No additional legal opinion, other information or
instructions shall be required of the Purchasers to exercise their Warrants or Pre-Funded Warrants. Without limiting the preceding sentences,
no ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of
any Notice of Exercise form be required in order to exercise the Warrants or Pre-Funded Warrants. The Company shall honor exercises of
the Warrants and Pre-Funded Warrants and shall deliver Warrant Shares and Pre-Funded Warrant Shares in accordance with the terms, conditions
and time periods set forth in the Transaction Documents. Notwithstanding anything contained in this Agreement to the contrary, in no event
shall the exercise price of any Warrant or any Pre-Funded Warrant be adjusted below the nominal value (or U.S. dollar equivalent) of the
Common Shares, which is CHF 0.02 as of the date of this Agreement.

 

4.16 Form
D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Warrant and Warrant Shares as required under Regulation
D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably
determine is necessary in order to obtain an exemption for, or to qualify the Warrant and Warrant Shares for, sale to the Purchasers at
the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence
of such actions promptly upon request of any Purchaser.

 

4.17 Registration
Statement. As soon as practicable (and in any event within 60 calendar days of the date of this Agreement), the Company shall file
a registration statement on Form F-1 (or Form F-3, if available) providing for the resale by the Purchasers of the Warrant Shares issued
and issuable upon exercise of the Warrants (the “Resale Registration Statement”). The Company shall use commercially
reasonable efforts to cause such Resale Registration Statement to become effective within ninety (90) calendar days following the Closing
Date and to keep such Resale Registration Statement effective at all times until no Purchaser owns any Warrants or Warrant Shares issuable
upon exercise thereof.

on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the Closing has not been consummated

breach by any other party (or parties).

 

5.2 Fees

the case of an amendment, by the Company and Purchasers which purchased at least 50.1% in interest of the Shares based on the initial
Subscription Amounts hereunder or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought,
provided that if any amendment, modification or waiver disproportionately and adversely impacts a Purchaser (or group of Purchasers),
the consent of such disproportionately impacted Purchaser (or group of Purchasers) shall also be required. No waiver of any default with
respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver
of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any
party to exercise any right hereunder in any manner impair the exercise of any such right. Any proposed amendment or waiver that disproportionately,
materially and adversely affects the rights and obligations of any Purchaser relative to the comparable rights and obligations of the
other Purchasers shall require the prior written consent of such adversely affected Purchaser. Any amendment effected in accordance with
this Section 5.5 shall be binding upon each Purchaser and holder of Securities and the Company.

and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns.
The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser (other

transfers any Securities, provided that such transferee agrees in writing to be bound, with respect to the transferred Securities, by
the provisions of the Transaction Documents that apply to the “Purchasers.”

enforced by, any other Person, except as otherwise set forth in Section 4.8 and this Section 5.8.

shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles
of conflicts of law thereof. Each party agrees that all legal Proceedings concerning the interpretations, enforcement and defense of the
transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective
affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and
federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or
with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents),
and hereby irrevocably waives, and agrees not to assert in any Action or Proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such Action or Proceeding is improper or is an inconvenient venue for such Proceeding. Each party
hereby irrevocably waives personal service of process and consents to process being served in any such Action or Proceeding by mailing
a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect
for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law.
If any party shall commence an Action or Proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations
of the Company under Section 4.8, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for
its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such
Action or Proceeding.

 

The Company hereby irrevocably
designates and appoints Puglisi & Associates (the “Process Agent”) as its authorized agent upon whom process may
be served in any claim brought against the Company, it being understood that the designation and appointment of the Process Agent as such
authorized agent shall become effective immediately without any further action on the part of the Company. The Company represents to each
Purchaser that it has notified the Process Agent of such designation and appointment and that the Process Agent has accepted the same.
The Company hereby irrevocably authorizes and directs the Process Agent to accept such service. The Company further agrees that service
of process upon the Process Agent and written notice of said service to the Company, mailed by first-class mail and delivered to the Process
Agent, shall be deemed in every respect effective service of process upon the Company in any such claim. Nothing herein shall affect the
right of each Purchaser, its partners, directors, officers and members, any person who controls any Purchaser within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act, or any “affiliate” (within the meaning of Rule 405 under the Securities
Act) of such Purchaser, or the successors and assigns of all of the foregoing persons, to serve process in any other manner permitted
by law. The provisions of this Section 5.9 shall survive any termination of this Agreement, in whole or in part.

 

5.10 Survival.
The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.

 

    40

     

    

 

5.11 Execution.
This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that
the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery
of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose
behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original
thereof.

 

5.12 Severability.
If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force
and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts
to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

 

5.13 Rescission
and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of
the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and
the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw,
in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part
without prejudice to its future actions and rights; provided, however, that in the case of a rescission of an exercise of a Warrant or
Pre-Funded Warrant, the applicable Purchaser shall be required to return any Common Shares subject to any such rescinded exercise notice
concurrently with the return to such Purchaser of the aggregate exercise price paid to the Company for such shares and the restoration
of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant or Pre-Funded Warrant (including, issuance
of a replacement warrant certificate evidencing such restored right).

 

5.14 Replacement
of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall
issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of
and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of
such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable
third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

 

5.15 Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers
and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may
not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby
agree to waive and not to assert in any Action for specific performance of any such obligation the defense that a remedy at law would
be adequate. Each party hereto agrees that it shall not have a remedy of punitive or consequential damages against the other and hereby
waives any right or claim to punitive or consequential damages it may now have or may arise in the future.

 

    41

     

    

 

5.16 Payment
Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser
enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required
to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without
limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration
the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred.

 

5.17 Independent
Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and
not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance
of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document,
and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association,
a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group
with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled to independently
protect and enforce its rights including, without limitation, the rights arising out of this Agreement or out of the other Transaction
Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose.
Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. For
reasons of administrative convenience only, each Purchaser and its respective counsel have chosen to communicate with the Company through
Blank Rome. Blank Rome does not represent any of the Purchasers and only represents the Placement Agent. The Company has elected to provide
all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested
to do so by any of the Purchasers. It is expressly understood and agreed that each provision contained in this Agreement and in each other
Transaction Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not
between and among the Purchasers.

 

5.18 Liquidated
Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction Documents
is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been
paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts are due
and payable shall have been canceled.

 

5.19 Saturdays, Sundays,
Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein
shall not be a Business Day, then such action may be taken or such right may be exercised on the next succeeding Business Day.

 

5.20 Construction.
The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction Documents
and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall
not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and every reference to
share prices and Common Shares in any Transaction Document shall be subject to adjustment for reverse and forward share splits, stock
dividends, share combinations and other similar transactions of the Common Shares that occur after the date of this Agreement.

 

5.21 WAIVER
OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES
EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY
AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.

Attention: Alexander Zwyer 

   Chief Executive
Officer

 

Dear Mr. Zwyer:

 

	Re:	Registered Direct Offering of Common Shares and Concurrent
	 	Private Placement of Common Share Purchase Warrants

 

This letter (the “Agreement”)
constitutes the agreement between A.G.P./Alliance Global Partners (the “Placement Agent”) and NLS Pharmaceutics
Ltd., a company organized under the laws of Switzerland (the “Company”), that the Placement Agent shall serve as the
placement agent for the Company, on a “reasonable best efforts” basis, in connection with the proposed placement (the “Placement”)
of common shares of the Company, par CHF 0.02 per share (the “Common Shares”), any pre-funded warrants to purchase
common shares (“Pre-Funded Warrants”), and the common share purchase warrants to purchase Common Shares (the “Investor
Warrants”, and together with the Common Shares and Pre-Funded Warrants, the “Securities”). The Securities
actually placed by the Placement Agent are referred to herein as the “Placement Agent Securities.” The
terms of the Placement shall be mutually agreed upon by the Company and the purchasers (each, a “Purchaser” and collectively,
the “Purchasers”), and nothing herein constitutes that the Placement Agent would have the power or authority to bind
the Company or any Purchaser, or an obligation for the Company will issue any Securities or complete the Placement. The Company expressly
acknowledges and agrees that the Placement Agent’s obligations hereunder are on a reasonable best efforts basis only and that the
execution of this Agreement does not constitute a commitment by the Placement Agent to purchase the Securities and does not ensure the
successful placement of the Securities or any portion thereof or the success of the Placement Agent with respect to securing any other
financing on behalf of the Company. Upon the written consent of the Company, the Placement Agent may retain other brokers or dealers to
act as sub-agents or selected-dealers on its behalf in connection with the Placement. Certain affiliates of the Placement Agent may participate
in the Placement by purchasing some of the Placement Agent Securities. The sale of Placement Agent Securities to any Purchaser will be
evidenced by a securities purchase agreement (the “Purchase Agreement”) between the Company and such Purchaser,
in a form reasonably acceptable to the Company and the Purchaser. Capitalized terms that are not otherwise defined herein have the meanings
given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, officers of the Company will be available
to answer inquiries from prospective Purchasers.

 

SECTION 1. REPRESENTATIONS
AND WARRANTIES OF THE COMPANY; COVENANTS OF THE COMPANY.

 

A. Representations of
the Company. Each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made
by the Company to the Purchasers in the Purchase Agreement in connection with the Placement is hereby incorporated herein by reference
into this Agreement (as though fully restated herein) and is, as of the date of this Agreement and as of the Closing Date, hereby made
to, and in favor of, the Placement Agent. In addition to the foregoing, the Company represents and warrants that:

 

    1

     

    

 

1. The Company has
prepared and filed with the Commission a registration statement on Form F-3 (Registration No. 333-262489), and amendments thereto,
and related preliminary prospectuses, for the registration under the Securities Act of 1933, as amended (the “Securities
Act”), of the applicable Securities, which registration statement, as so amended (including post-effective amendments, if
any) became effective on February 11, 2022. At the time of such filing, the Company met the requirements of Form F-3 under the
Securities Act. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and
complies with said Rule. The Company will file with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules
and regulations (the “Rules and Regulations”) of the Commission promulgated thereunder, a supplement to the form
of prospectus included in such registration statement relating to the placement of the Shares and the plan of distribution thereof
and has advised the Placement Agent of all further information (financial and other) with respect to the Company required to be set
forth therein. Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter
called the “Registration Statement”; such prospectus in the form in which it appears in the Registration
Statement is hereinafter called the “Base Prospectus”; and the supplemented form of prospectus, in the form in
which it will be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter
called the “Prospectus Supplement.” Any reference in this Agreement to the Registration Statement, the Base
Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by reference therein (the
“Incorporated Documents”) pursuant to Item 6 of Form F-3 which were filed under the Securities Exchange Act of
1934, as amended (the “Exchange Act”), on or before the date of this Agreement, or the issue date of the Base
Prospectus or the Prospectus Supplement, as the case may be; and any reference in this Agreement to the terms “amend,”
“amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus or the
Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of
this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated
therein by reference. All references in this Agreement to financial statements and schedules and other information which is
“contained,” “included,” “described,” “referenced,” “set forth” or
“stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of
like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is
deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case
may be. No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus
Supplement has been issued, and no proceeding for any such purpose is pending or has been initiated or, to the Company’s
knowledge, is threatened by the Commission. For purposes of this Agreement, “Free Writing Prospectus” has the
meaning set forth in Rule 405 under the Securities Act and the “Time of Sale Prospectus” means the preliminary
prospectus, if any, together with the Free Writing Prospectuses, if any, used in connection with the Placement, including any
documents incorporated by reference therein.

 

2. The Registration Statement
(and any further documents to be filed with the Commission) contains all exhibits and schedules as required by the Securities Act. Each
of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects
with the Securities Act and the Exchange Act and the applicable Rules and Regulations and did not and, as amended or supplemented, if
applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. The Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement,
each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable Rules
and Regulations. Each of the Base Prospectus, the Time of Sale Prospectus and the Prospectus Supplement, as amended or supplemented, did
not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Incorporated Documents,
when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange Act and the applicable
Rules and Regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material
fact or omitted to state a material fact necessary to make the statements therein (with respect to Incorporated Documents incorporated
by reference in the Base Prospectus or Prospectus Supplement), in the light of the circumstances under which they were made not misleading;
and any further documents so filed and incorporated by reference in the Base Prospectus, the Time of Sale Prospectus or Prospectus Supplement,
when such documents are filed with the Commission, will conform in all material respects to the requirements of the Exchange Act and the
applicable Rules and Regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a material
fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. No post-effective
amendment to the Registration Statement reflecting any facts or events arising after the date thereof which represent, individually or
in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission. There are no
documents required to be filed with the Commission in connection with the transaction contemplated hereby that (x) have not been filed
as required pursuant to the Securities Act or (y) will not be filed within the requisite time period. There are no contracts or other
documents required to be described in the Base Prospectus, the Time of Sale Prospectus or Prospectus Supplement, or to be filed as exhibits
or schedules to the Registration Statement, which (x) have not been described or filed as required or (y) will not be filed within the
requisite time period.

 

    2

     

    

 

3. There are no affiliations
with any FINRA member firm among the Company’s officers, directors or, to the knowledge of the Company, any five percent (5.0%)
or greater securityholder of the Company, except as set forth in the Purchase Agreement.

  

B. Covenants of the
Company. The Company covenants and agrees to continue to retain (i) a firm of independent PCAOB registered public accountants for
a period of at least five (5) years after the Closing Date and (ii) a competent transfer agent with respect to the Common Shares for a
period of five (5) years after the Closing Date. In addition, from the date hereof until sixty (60) days after the Closing Date, neither
the Company nor any Subsidiary shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any Common
Shares or Common Share Equivalents, except that such restriction shall not apply with respect to an Exempt Issuance.

 

SECTION 2. REPRESENTATIONS
OF THE PLACEMENT AGENT. The Placement Agent represents and warrants that it (i) is a member in good standing of FINRA, (ii) is
registered as a broker/dealer under the Exchange Act, (iii) is licensed as a broker/dealer under the laws of the United States of
America, applicable to the offers and sales of the Placement Agent Securities by the Placement Agent, (iv) is and will be a
corporate body validly existing under the laws of its place of incorporation, and (v) has full power and authority to enter into and
perform its obligations under this Agreement. The Placement Agent will immediately notify the Company in writing of any change in
its status with respect to subsections (i) through (v) above. The Placement Agent covenants that it will use its reasonable best
efforts to conduct the Placement hereunder in compliance with the provisions of this Agreement and the requirements of applicable
law.

 

SECTION 3.
COMPENSATION/EXPENSES. In consideration of the services to be provided for hereunder, the Company shall pay to the Placement
Agent and/or its respective designees a cash fee of 7.0% of the aggregate gross proceeds raised from the sale of the Placement Agent
Securities (the “Cash Fee”) and a cash fee of up to $5,000 for non-accountable expenses (the “NAE
Expenses”), provided, however that no Cash Fee shall be owed for any Placement Agent Securities sold to a Company
introduced party (a “Company Introduced Party”). The Cash Fee and the NAE Expenses shall be paid on the Closing
Date from the gross proceeds of Placement Agent Securities sold. The Company shall not be required to pay the Placement Agent any
fees or expenses except for the Cash Fee, the NAE Expenses and the reimbursement of up to $50,000 in legal expenses, provided,
however, that this sentence in no way limits or impairs the indemnification or contribution provisions contained herein, and
provided further that such fees are payable only if the sale of securities pursuant to the Purchase Agreement is consummated. The
Placement Agent reserves the right to reduce any item of compensation or adjust the terms thereof as specified herein in the event
that a determination shall be made by FINRA to the effect that the Placement Agent’s aggregate compensation is in excess of
FINRA Rules or that the terms thereof require adjustment. In addition, The Company shall bear the cost of any escrow agent with whom
an escrow agreement with respect to the Placement is entered into and the cost of any clearing agent, if any, in connection with the
offering and settlement of the Securities up to $10,000.

  

    3

     

    

 

SECTION 4.
INDEMNIFICATION.

 

A. To the extent permitted
by law, with respect to the Placement Agent Securities, the Company will indemnify the Placement Agent and its affiliates, stockholders,
directors, officers, employees, members and controlling persons (within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act) against all losses, claims, damages, expenses and liabilities, as the same are incurred (including the reasonable
fees and expenses of counsel), relating to or arising out of its activities hereunder or pursuant to this Agreement, except to the extent
that any losses, claims, damages, expenses or liabilities (or actions in respect thereof) are found in a final judgment (not subject to
appeal) by a court of law to have resulted primarily and directly from the Placement Agent’s fraud, bad faith, willful misconduct
or gross negligence in performing the services described herein.

 

B. Promptly after receipt
by the Placement Agent of notice of any claim or the commencement of any action or proceeding with respect to which the Placement Agent
is entitled to indemnity hereunder, the Placement Agent will notify the Company in writing of such claim or of the commencement of such
action or proceeding, but failure to so notify the Company shall not relieve the Company from any obligation it may have hereunder, except
and only to the extent such failure results in the forfeiture by the Company of substantial rights and defenses. If the Company so elects
or is requested by the Placement Agent, the Company will assume the defense of such action or proceeding and will employ counsel reasonably
satisfactory to the Placement Agent and will pay the fees and expenses of such counsel. Notwithstanding the preceding sentence, the Placement
Agent will be entitled to employ counsel separate from counsel for the Company and from any other party in such action if counsel for
the Placement Agent reasonably determines that it would be inappropriate under the applicable rules of professional responsibility for
the same counsel to represent both the Company and the Placement Agent. In such event, the reasonable fees and disbursements of no more
than one such separate counsel will be paid by the Company, in addition to fees of local counsel. The Company will have the right to settle
the claim or proceeding provided that the Company will not settle any such claim, action or proceeding without the prior written consent
of the Placement Agent, which will not be unreasonably withheld. The Company shall not be liable for any settlement of any action effected
without its written consent, which will not be unreasonably withheld.

 

C. The Company agrees to notify
the Placement Agent promptly of the assertion against it or any other person of any claim or the commencement of any action or proceeding
relating to a transaction contemplated by this Agreement.

 

D. If for any reason the foregoing
indemnity is unavailable to the Placement Agent or insufficient to hold the Placement Agent harmless, then the Company shall contribute
to the amount paid or payable by the Placement Agent as a result of such losses, claims, damages or liabilities in such proportion as
is appropriate to reflect not only the relative benefits received by the Company, on the one hand, and the Placement Agent, on the other,
but also the relative fault of the Company, on the one hand, and the Placement Agent, on the other, that resulted in such losses, claims,
damages or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses,
claims, damages and liabilities referred to above shall be deemed to include any legal or other fees and expenses incurred in defending
any litigation, proceeding or other action or claim. Notwithstanding the provisions hereof, the Placement Agent’s share of the liability
hereunder shall not be in excess of the amount of fees actually received, or to be received, by the Placement Agent under this Agreement
(excluding any amounts received as reimbursement of expenses incurred by the Placement Agent).

  

    4

     

    

 

E. These indemnification provisions
shall remain in full force and effect whether or not the transaction contemplated by this Agreement is completed and shall survive the
termination of this Agreement, and shall be in addition to any liability that the Company might otherwise have to any indemnified party
under this Agreement or otherwise.

 

SECTION 5. ENGAGEMENT
TERM. The Placement Agent’s engagement hereunder will be until the earlier of (i) May 6, 2022 and (ii) the Closing Date. The
date of termination of this Agreement is referred to herein as the “Termination Date.” In the event, however, in the
course of the Placement Agent’s performance of due diligence it deems it necessary to terminate the engagement, the Placement Agent
may do so prior to the Termination Date. The Company may elect to terminate the engagement hereunder for any reason prior to the Termination
Date but will remain responsible for fees and expenses pursuant to Section 3 hereof and fees with respect to the Placement Agent Securities
if sold in the Placement. Notwithstanding anything to the contrary contained herein, the provisions concerning the Company’s obligation
to pay any fees actually earned pursuant to Section 3 hereof, to pay expenses pursuant to Section 3 hereof, and the provisions concerning
confidentiality, indemnification and contribution contained herein will survive any expiration or termination of this Agreement. If this
Agreement is terminated prior to the completion of the Placement, all fees and expenses due to the Placement Agent shall be paid by the
Company to the Placement Agent on or before the Termination Date (in the event such fees are earned or owed as of the Termination Date).
The Placement Agent agrees not to use any confidential information concerning the Company provided to the Placement Agent by the Company
for any purposes other than those contemplated under this Agreement.

 

SECTION 6. PLACEMENT
AGENT INFORMATION. The Company agrees that any information or advice rendered by the Placement Agent in connection with this engagement
is for the confidential use of the Company only in their evaluation of the Placement and, except as otherwise required by law, the Company
will not disclose or otherwise refer to the advice or information in any manner without the Placement Agent’s prior written consent.

 

SECTION 7. NO
FIDUCIARY RELATIONSHIP. This Agreement does not create, and shall not be construed as creating rights enforceable by any person or
entity not a party hereto, except those entitled hereto by virtue of the indemnification provisions hereof. The Company acknowledges and
agrees that the Placement Agent is not and shall not be construed as a fiduciary of the Company and shall have no duties or liabilities
to the equity holders or the creditors of the Company or any other person by virtue of this Agreement or the retention of the Placement
Agent hereunder, all of which are hereby expressly waived.

 

SECTION 8. CLOSING.
The obligations of the Placement Agent, and the closing of the sale of the Placement Agent Securities hereunder are subject to the accuracy,
when made and on the Closing Date, of the representations and warranties on the part of the Company contained herein and in the Purchase
Agreement, to the performance by the Company of its obligations hereunder and in the Purchase Agreement, and to each of the following
additional terms and conditions, except as otherwise disclosed to and acknowledged and waived by the Placement Agent:

 

A. All corporate proceedings

written consent of the other party. This Agreement shall be binding upon and inure to the benefit of the parties hereto, and their
respective successors and permitted assigns. Any right to trial by jury with respect to any dispute arising under this Agreement or
any transaction or conduct in connection herewith is waived. Any dispute arising under this Agreement may be brought into the courts

the Company hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of aforesaid
courts. Each party hereto hereby irrevocably waives personal service of process and consents to process being served in any such
suit, action or proceeding by delivering a copy thereof via overnight delivery (with evidence of delivery) to such party at the

warranties, agreements and covenants contained herein shall survive the Closing Date of the Placement and delivery of the Placement
Agent Securities. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other
party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by

original thereof.
