 MERCK & CO., INC. 

Officers’ Certificate 

Pursuant to the resolutions (collectively, the “Resolutions”) of the Board of Directors of Merck & Co., Inc. (the
“Company”) adopted at meetings duly called and held on March 23, 2021 and November 30, 2021 (at which meetings a quorum was present and acting throughout), which authorized the Company to issue and sell its debt securities and
empowered an Authorized Officer (as defined in the Resolutions) to approve the form and terms of such debt securities, Aaron Rosenberg, Senior Vice President and Treasurer and Kelly E. W. Grez, Deputy Corporate Secretary, each hereby approves and
establishes under the Indenture, dated as of January 6, 2010 (the “Indenture”), between the Company and U.S. Bank Trust National Association, as Trustee (the “Trustee”), a series of debt securities the terms of which are as
follows: 
 1. The title of the debt securities of such series shall be 2.900% Notes due 2061 (the “2061 Notes”).

 2. The aggregate principal amount of the 2061 Notes which may be authenticated and delivered under the Indenture is
initially limited to $1,500,000,000, except for 2061 Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of, other 2061 Notes of the series pursuant to Section 304, 305, 306, 906 or 1107 of the
Indenture and except for any 2061 Notes which, pursuant to Section 303 of the Indenture, are deemed never to have been authenticated and delivered under the Indenture. 

3. The Company shall have the right from time to time, without the consent of the Holders of the 2061 Notes, to create and
issue additional notes with the same terms and conditions as the 2061 Notes except for the issue date, issue price and the first payment of interest thereon (“Additional Notes”), provided that if the Additional Notes are not fungible with
the previously outstanding 2061 Notes for U.S. federal income tax purposes, such Additional Notes will have a separate CUSIP. Additional Notes will be consolidated with and will form a single series with the previously outstanding 2061 Notes. Any
election by the Company to so increase such aggregate principal amount shall be evidenced by a certificate of an Authorized Officer or Authorized Officers. No Additional Notes may be issued if an Event of Default has occurred or is continuing with
respect to the 2061 Notes. 

 4. The 2061 Notes shall be issued in denominations of $2,000 and integral
multiples of $1,000 in excess thereof. 
 5. The proceeds to the Company (after deducting the underwriting discounts and
commissions but before deducting certain expenses payable by the Company in connection with the issuance of the 2061 Notes) shall be 98.918% of the aggregate principal amount of the 2061 Notes. 

6. The maturity date on which the principal of each of the 2061 Notes is payable shall be December 10, 2061. 

7. The 2061 Notes shall bear interest at the rate of 2.900% per annum from (and including) December 10, 2021. Interest
shall be payable on each Interest Payment Date and at the maturity date. Interest payments shall be in the amount of interest accrued to, but excluding, the relevant Interest Payment Date or the maturity date, as applicable. 

8. The Interest Payment Dates for the 2061 Notes shall be June 10 and December 10 of each year, commencing on
June 10, 2022, and the Regular Record Dates for the 2061 Notes shall be the preceding May 25 or November 25, as the case may be. 

If any payment date for the 2061 Notes is not a business day, the Company will make the payment on the next business day, but
the Company will not be liable for any additional interest as a result of the delay in payment. With respect to the 2061 Notes, business day means any Monday, Tuesday, Wednesday, Thursday or Friday which is not a day when banking institutions in the
place of payment are authorized or obligated by law or executive order to be closed. 
 9. The Company may, at its option,
redeem some or all of the 2061 Notes prior to the Par Call Date (as defined below) at any time or from time to time, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the 2061 Notes to be redeemed or (ii) the sum
of the present values of the Remaining Scheduled Payments (as defined below) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve
30-day months) at a rate equal to the Reinvestment Rate (as defined below) plus 20 basis points, plus, in each case, any interest accrued but not paid to the Redemption Date. 

On or after the Par Call Date, the Company may redeem the 2061 Notes in whole at any time or in part from time to time, at the
Company’s option, at a Redemption Price equal to 100% of the principal amount of the 2061 Notes being redeemed, plus any interest accrued but not paid to, but excluding, the Redemption Date. 

Notice of redemption will be provided on at least 10 days’, but no more than 60 days’, prior notice mailed to the
registered address of each Holder of the 2061 Notes. The principal amount of a 2061 Note remaining outstanding after a redemption in part shall be $2,000 or an integral multiple of $1,000 in excess thereof. 

  
 2 

 The term “Par Call Date” means June 10, 2061, the date that
is six months prior to the maturity of the 2061 Notes. 
 The “Reinvestment Rate” means, as determined on the
third business day preceding the date the notice of redemption is provided, the arithmetic mean of the yields under the respective heading “Week Ending” published in the most recent Statistical Release under the caption “Treasury
Constant Maturities” for the maturity, rounded to the nearest month, corresponding to the remaining life to the Par Call Date, as of the payment date of the principal being redeemed or paid. If no maturity exactly corresponds to such remaining
life to the Par Call Date, yields for the two published maturities most closely corresponding to such remaining life to the Par Call Date shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be
interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For the purpose of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the
date of determination shall be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the treasury yield in the above manner, then the treasury yield shall be determined in the manner that most
closely approximates the above manner, as reasonably determined by the Company in consultation with the Trustee. 

“Remaining Scheduled Payments” means, with respect to each 2061 Note to be redeemed, the remaining scheduled
payments of principal and interest that would be due after the related Redemption Date but for the redemption if the 2061 Notes matured on the Par Call Date. If the Redemption Date is not an Interest Payment Date, the amount of the next succeeding
scheduled interest payment on the 2061 Note will be reduced by the amount of interest accrued on the 2061 Note to the Redemption Date. 

“Statistical Release” means the statistical release designated “H.15 (519)” or any successor publication
which is published weekly by the Federal Reserve System and which reports yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any
determination, then such other reasonably comparable index which shall be designated by the Company. 
 If fewer than all of
the 2061 Notes are to be redeemed, the Trustee will select the particular 2061 Notes or portions thereof for redemption from the outstanding 2061 Notes not previously called, pro rata or by lot, or in such other manner as the Company shall direct.

 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to
accrue on the 2061 Notes or portions thereof called for redemption. 
 10. Payment of the principal and interest on the 2061
Notes will be made at the office or agency of the Company maintained for that purpose in New York, New York (initially, the Corporate Trust Office of the Trustee), provided that at the option of the Company payment of interest may be made by
check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 

  
 3 

 11. The provisions on defeasance and covenant defeasance in Article Thirteen
of the Indenture shall apply to the 2061 Notes. 
 12. The 2061 Notes shall be issued in the form of one or more Book-Entry
Securities and the Depository for such Book-Entry Securities shall be The Depository Trust Company, Clearstream Banking societé anonyme and Euroclear Bank S.A./N.V. 

13. The form of the 2061 Notes attached hereto as Annex A is hereby approved. 

Capitalized terms used herein and not otherwise defined herein have the meanings specified in the Indenture.

2.900% NOTES DUE 2061 

This Security is a Book-Entry Security within the meaning of the Indenture referred to on the reverse hereof and is registered in the name of
a Depository or a nominee of a Depository. This Security is exchangeable for Securities registered in the name of a Person other than the Depository or its nominee only in the limited circumstances described in the Indenture and this Security may
not be transferred except as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository. 

Unless this Certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation
(“DTC”), to the Company or its agent for registration of transfer, exchange or payment, and any Certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of
DTC (and any payment hereon is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
the registered owner hereof, Cede & Co., has an interest herein. 
  

	1 	 On December 10, 2021, the 2061 Notes will be issued in the form of three Book-Entry Securities in the
principal amounts of $500,000,000, $500,000,000 and $500,000,000. 

  
 A-1 

 Merck & Co., Inc., a New Jersey corporation (hereinafter called the
“Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., as nominee for The Depository Trust Company, or registered assigns,
the principal sum of [•] Hundred Million Dollars ($[•]) on December 10, 2061, and to pay interest thereon from and including December 10, 2021 or from the most recent Interest Payment Date to which interest has been paid or duly
provided for, semi-annually in arrears on June 10 and December 10 in each year and at Maturity, commencing on June 10, 2022, at a rate per annum of 2.900%, until the principal hereof is paid or made available for payment, and (to the
extent that the payment of such interest shall be legally enforceable) at the interest rate specified above on any overdue principal and premium and on any overdue installment of interest. The interest so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such
interest, which shall be the May 25 or November 25 (whether or not a Business Day in New York City), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. 

The Company will at all times appoint and maintain a Paying Agent (which may be the Trustee) authorized by the Company to pay the principal of
(and premium, if any) or interest on any Securities of this series on behalf of the Company and having an office or agency (the “Paying Agent Office”) in The City of New York, where Securities of this series may be presented or surrendered
for payment and where notices, designations or requests in respect of payments with respect to Securities of this series may be served. The Company has initially appointed U.S. Bank Trust National Association as such Paying Agent, with the Paying
Agent Office currently at 100 Wall Street, New York, New York 10005. The Company will give prompt written notice to the Trustee of any change in such appointment. 

Payment of the principal of (and premium, if any) and interest on this Security will be made in immediately available funds upon surrender of
such Security at the Corporate Trust Office of U.S. Bank Trust National Association, in the Borough of Manhattan, The City of New York in such coin or currency of the United States of America as at the time of payment is legal tender for payment of
public and private debts. Payments of interest on any Security of this series (other than at the Maturity of such Security) will be made by check mailed to the address of the Person entitled thereto as it appears in the Security Register or by wire
transfer to such account as may have been appropriately designated in writing no later than the relevant Regular Record Date to the Paying Agent by such Person. 

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

“Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. 

The terms of the Securities include those stated in the Indenture and in the Officers’ Certificate dated December 10, 2021 (the
“Officers’ Certificate”). This Security is subject to the terms in the Indenture and the Officers’ Certificate, and Holders are referred to the Indenture and the Officers’ Certificate for a statement of such terms. All terms
used but not defined in this Security which are defined in the Indenture or in the Officers’ Certificate shall have the meanings assigned to them in the Indenture or Officers’ Certificate, as applicable. 

This Security is one of the series designated on the face hereof. The aggregate principal amount of such series is $1,500,000,000 provided
that the Company may increase such aggregate principal amount at any time. 
 The Company shall have the right from time to time, without
the consent of the Holders of the 2061 Notes, to create and issue additional notes with the same terms and conditions as the 2061 Notes except for the issue date, issue price and the first payment of interest thereon (“Additional Notes”),
provided that if the Additional Notes are not fungible with the previously outstanding 2061 Notes for U.S. federal income tax purposes, such Additional Notes will have a separate CUSIP. Additional Notes will be consolidated with and will form a
single series with the previously outstanding 2061 Notes. Any election by the Company to so increase such aggregate principal amount shall be evidenced by a certificate of an Authorized Officer or Authorized Officers. No Additional Notes may be
issued if an Event of Default has occurred or is continuing with respect to the 2061 Notes. 
 Payments of interest hereon with respect to
any Interest Payment Date will include interest accrued to but excluding such Interest Payment Date. Interest hereon shall be computed on the basis of a 360-day year consisting of twelve 30-day months. 
 This Security is not subject to any sinking fund. 

The Company may, at its option, redeem some or all of the Securities prior to the Par Call Date (as defined below) at any time or from time to
time, at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments (as defined below) discounted to the Redemption Date
on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the Reinvestment Rate (as defined below) plus 20 basis points,
plus, in each case, any interest accrued but not paid to the Redemption Date; provided that the principal amount of a Security remaining outstanding after a redemption in part shall be $2,000 or an integral multiple of $1,000 in excess
thereof. 

  
 A-5 

 On or after June 10, 2061 (six months prior to the Stated Maturity of the Securities,
or the “Par Call Date”), the Company may redeem the Securities in whole at any time or in part from time to time, at the Company’s option, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed,
plus any interest accrued but not paid to, but excluding, the Redemption Date. 
 “Reinvestment Rate” means, as determined on the
third business day preceding the date the notice of redemption is provided, the arithmetic mean of the yields under the respective heading “Week Ending” published in the most recent Statistical Release under the caption “Treasury
Constant Maturities” for the maturity, rounded to the nearest month, corresponding to the remaining life to the Par Call Date, as of the payment date of the principal being redeemed or paid. If no maturity exactly corresponds to such remaining
life to the Par Call Date, yields for the two published maturities most closely corresponding to such remaining life to the Par Call Date shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be
interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For the purpose of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the
date of determination shall be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the treasury yield in the above manner, then the treasury yield shall be determined in the manner that most
closely approximates the above manner, as reasonably determined by the Company in consultation with the Trustee. 
 “Remaining
Scheduled Payments” means, with respect to each Security to be redeemed, the remaining scheduled payments of principal and interest on the Security that would be due after the related Redemption Date but for the redemption, if such Security
matured on the Par Call Date. If that Redemption Date is not an Interest Payment Date with respect to a Security, the amount of the next succeeding scheduled interest payment on the Security will be reduced by the amount of interest accrued on the
Security to the Redemption Date. 
 “Statistical Release” means the statistical release designated “H.15 (519)” or any
successor publication which is published weekly by the Federal Reserve System and which reports yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the
time of any determination, then such other reasonably comparable index which shall be designated by the Company. 
 Holders of Securities to
be redeemed will receive notice thereof by first-class mail at least 10 and not more than 60 days before the date fixed for redemption. If fewer than all of the Securities are to be redeemed, the Trustee will select the particular Securities or
portions thereof for redemption from the outstanding Securities not previously called, pro rata or by lot, or in such other manner as the Company shall direct. 

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the
Securities or portions thereof called for redemption. 
 If an Event of Default with respect to the Securities of this series shall occur
and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. 

  
 A-6 

 The Indenture contains provisions for defeasance at any time of (i) the entire
indebtedness of this Security or (ii) certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth therein. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the
time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all
Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange thereof or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair
the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the
Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000
in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Certificate, which shall be deposited with the Warrant Agent and registered in the name of Cede & Co., a nominee of The Depository
Trust Company (the “Depositary”), or as otherwise directed by the Depositary. Ownership of beneficial interests in
the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the Depositary
or its nominee for each Global Warrant or (ii) institutions that have accounts with the Depositary (such institution, with respect
to a Warrant in its account, a “Participant”).

 

(b) If the Depositary
subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding
other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have
the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant
Agent for cancellation each Global Warrant, and the Company shall instruct the Warrant Agent to deliver to each Holder a Warrant Certificate.

 

(c)  A Holder has the
right to elect at any time or from time to time a Warrant Exchange (as defined below) pursuant to a Warrant Certificate Request Notice
(as defined below). Upon written notice by a Holder to the Company and the Warrant Agent for the exchange of some or all of such Holder’s
Global Warrants for a separate certificate in the form attached hereto as Exhibit 1 (such separate certificate, a “Definitive
Certificate”) evidencing the same number of Warrants, which request shall be in the form attached hereto as Exhibit 2
(a “Warrant Certificate Request Notice” and the date of delivery of such Warrant Certificate Request Notice by the
Holder, the “Warrant Certificate Request Notice Date” and the surrender by the Holder to the Warrant Agent of a number
of Global Warrants for the same number of Warrants evidenced by a Warrant Certificate, a “Warrant Exchange”), the Company
and the Warrant Agent shall promptly effect the Warrant Exchange and the Company shall promptly issue and deliver to the Holder a Definitive
Certificate for such number of Warrants in the name set forth in the Warrant Certificate Request Notice. Such Definitive Certificate shall
be dated the original issue date of the Warrants, shall be manually executed by an authorized signatory of the Company, shall be in the
form attached hereto as Exhibit 1 and shall be reasonably acceptable in all respects to such Holder. In connection with a
Warrant Exchange, the Company agrees to deliver the Definitive Certificate to the Holder within ten (10) Business Days of the Warrant
Certificate Request Notice pursuant to the delivery instructions in the Warrant Certificate Request Notice (“Warrant Certificate
Delivery Date”). If the Company fails for any reason to deliver to the Holder the Definitive Certificate subject to the Warrant
Certificate Request Notice by the Warrant Certificate Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages
and not as a penalty, for each $1,000 of Warrant Shares evidenced by such Definitive Certificate (based on the VWAP (as defined in the
Warrants) of the Common Stock on the Warrant Certificate Request Notice Date), $10 per Business Day for each Business Day after such Warrant
Certificate Delivery Date until such Definitive Certificate is delivered or, prior to delivery of such Warrant Certificate, the Holder
rescinds such Warrant Exchange. The Company covenants and agrees that, upon the date of delivery of the Warrant Certificate Request Notice,
the Holder shall be deemed to be the holder of the Definitive Certificate and, notwithstanding anything to the contrary set forth herein,
the Definitive Certificate shall be deemed for all purposes to contain all of the terms and conditions of the Warrants evidenced by such
Warrant Certificate and the terms of this Agreement, other than Sections 3(c), 3(d) and 9 herein, shall not apply to the Warrants
evidenced by the Definitive Certificate. Notwithstanding anything herein to the contrary, the Company shall act as warrant agent with
respect to any Definitive Certificate requested and issued pursuant to this section. Notwithstanding anything to the contrary contained
in this Agreement, in the event of inconsistency between any provision in this Agreement and any provision in a Definitive Certificate,
as it may from time to time be amended, the terms of such Definitive Certificate shall control.

 

    3 

     

    

 

(d) A
Holder of a Definitive Certificate (pursuant to a Warrant Exchange or otherwise) has the right to elect at any time or from time to time
a Global Warrants Exchange (as defined below) pursuant to a Global Warrants Request Notice (as defined below). Upon written notice by
a Holder to the Company for the exchange of some or all of such Holder’s Warrants evidenced by a Definitive Certificate for a beneficial
interest in Global Warrants held in book-entry form through the Depositary evidencing the same number of Warrants, which request shall
be in the form attached hereto as Exhibit 3 (a “Global Warrants Request Notice” and the date of delivery
of such Global Warrants Request Notice by the Holder, the “Global Warrants Request Notice Date” and the surrender upon
delivery by the Holder of the Warrants evidenced by Definitive Certificates for the same number of Warrants evidenced by a beneficial
interest in Global Warrants held in book-entry form through the Depositary, a “Global Warrants Exchange”), the Company
shall promptly effect the Global Warrants Exchange and shall promptly direct the Warrant Agent to issue and deliver to the Holder Global
Warrants for such number of Warrants in the Global Warrants Request Notice, which beneficial interest in such Global Warrants shall be
delivered by the Depositary’s Deposit or Withdrawal at Custodian system to the Holder
pursuant to the instructions in the Global Warrants Request Notice. In connection with a Global Warrants Exchange, the Company shall direct
the Warrant Agent to deliver the beneficial interest in such Global Warrants to the Holder within ten (10) Business Days of the Global
Warrants Request Notice pursuant to the delivery instructions in the Global Warrant Request Notice (“Global Warrants Delivery
Date”). If the Company fails for any reason to deliver to the Holder Global Warrants subject to the Global Warrants Request
Notice by the Global Warrants Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty,
for each $1,000 of Warrant Shares evidenced by such Global Warrants (based on the VWAP (as defined in the Warrants) of the Common Stock
on the Global Warrants Request Notice Date), $10 per Business Day for each Business Day after such Global Warrants Delivery Date until
such Global Warrants are delivered or, prior to delivery of such Global Warrants, the Holder rescinds such Global Warrants Exchange. The
Company covenants and agrees that, upon the date of delivery of the Global Warrants Request Notice, the Holder shall be deemed to be the
beneficial holder of such Global Warrants.

 

Section 4. Form of
Warrant Certificates. The Warrant Certificate, together with the form of election to purchase Common Stock (“Notice of Exercise”)
and the form of assignment to be printed on the reverse thereof, shall be in the form of Exhibit 1 hereto.

 

Section 5. Countersignature
and Registration. The Global Warrant shall be executed on behalf of the Company by its Chief Executive Officer, Chief Financial Officer
or Vice President, by facsimile signature, and have affixed thereto the Company’s seal or a facsimile thereof which shall be attested
by the Secretary or an Assistant Secretary of the Company, by facsimile signature. The Global Warrant shall be countersigned by the Warrant
Agent by facsimile signature and shall not be valid for any purpose unless so countersigned. In case any officer of the Company who shall
have signed any of the Global Warrant shall cease to be such officer of the Company before countersignature by the Warrant Agent and issuance
and delivery by the Company, such Global Warrant, nevertheless, may be countersigned by the Warrant Agent, issued and delivered with the
same force and effect as though the person who signed such Global Warrant had not ceased to be such officer of the Company; and any Global
Warrant may be signed on behalf of the Company by any person who, at the actual date of the execution of such Global Warrant, shall be
a proper officer of the Company to sign such Global Warrant, although at the date of the execution of this Warrant Agreement any such
person was not such an officer.

 

The Warrant Agent will keep
or cause to be kept, at one of its offices, or at the office of one of its agents, books for registration and transfer of the Global Warrants
issued hereunder. Such books shall show the names and addresses of the respective Holders of the Global Warrant, the number of warrants
evidenced on the face of each of such Global Warrant and the date of each of such Global Warrant. The Warrant Agent will create a special
account for the issuance of Global Warrants. The Company will keep or cause to be kept at one of its offices, books for the registration
and transfer of any Definitive Certificates issued hereunder and the Warrant Agent shall not have any obligation to keep books and records
with respect to any Definitive Warrants. Such Company books shall show the names and addresses of the respective Holders of the Definitive
Certificates, the number of warrants evidenced on the face of each such Definitive Certificate and the date of each such Definitive Certificate.

 

    4 

     

    

 

Section 6. Transfer,
Split Up, Combination and Exchange of Warrant Certificates; Mutilated, Destroyed, Lost or Stolen Warrant Certificates. With respect
to the Global Warrant, subject to the provisions of the Warrant Certificate and the last sentence of this first paragraph of Section 6
and subject to applicable law, rules or regulations, or any “stop transfer” instructions the Company may give to the
Warrant Agent, at any time after the closing date of the Offering, and at or prior to the Close of Business on the Termination Date (as
such term is defined in the Warrant Certificate), any Global Warrant or Global Warrants may be transferred, split up, combined or exchanged
for another Global Warrant or Global Warrants, entitling the Holder to purchase a like number of shares of Common Stock as the Global
Warrant or Global Warrants surrendered then entitled such Holder to purchase. Any Holder desiring to transfer, split up, combine or exchange
any Global Warrant shall make such request in writing delivered to the Warrant Agent, and shall surrender the Global Warrant to be transferred,
split up, combined or exchanged at the principal office of the Warrant Agent. Any requested transfer of Warrants, whether in book-entry
form or certificate form, shall be accompanied by reasonable evidence of authority of the party making such request that may be required
by the Warrant Agent. Thereupon the Warrant Agent shall, subject to the last sentence of this first paragraph of Section 6, countersign
and deliver to the Person entitled thereto a Global Warrant or Global Warrants, as the case may be, as so requested. The Company may require
payment from the Holder of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer,
split up, combination or exchange of Global Warrants. The Company shall compensate the Warrant Agent per the fee schedule mutually agreed
upon by the parties hereto and provided separately on the date hereof.

 

Upon receipt by the Warrant
Agent of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of a Warrant Certificate, which evidence
shall include an affidavit of loss, or in the case of mutilated certificates, the certificate or portion thereof remaining, and, in case
of loss, theft or destruction, of indemnity in customary form and amount (but, with respect to any Definitive Certificates, shall not
include the posting of any bond by the Holder), and satisfaction of any other reasonable requirements established by Section 8-405
of the Uniform Commercial Code as in effect in the State of Delaware, and reimbursement to the Company and the Warrant Agent of all reasonable
expenses incidental thereto, and upon surrender to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the Company
will make and deliver a new Warrant Certificate of like tenor to the Warrant Agent for delivery to the Holder in lieu of the Warrant Certificate
so lost, stolen, destroyed or mutilated.

 

Section 7. Exercise
of Warrants; Exercise Price; Termination Date.

 

(a) The Warrants shall
be exercisable commencing on the Initial Exercise Date. The Warrants shall cease to be exercisable and shall terminate and become void
as set forth in the Warrant Certificate. Subject to the foregoing and to Section 7(b) below, the Holder of a Warrant may exercise
the Warrant in whole or in part upon surrender of the Warrant Certificate, if required, with the executed Notice of Exercise and payment
of the Exercise Price, which may be made, at the option of the Holder, by wire transfer or by certified or official bank check in United
States dollars, to the Warrant Agent at the principal office of the Warrant Agent or to the office of one of its agents as may be designated
by the Warrant Agent from time to time. In the case of the Holder of a Global Warrant, the Holder shall deliver the executed Notice of
Exercise and the payment of the Exercise Price as described herein. Notwithstanding any other provision in this Agreement, a holder whose
interest in a Global Warrant is a beneficial interest in a Global Warrant held in book-entry form through the Depositary (or another established
clearing corporation performing similar functions), shall effect exercises by delivering to the Depositary (or such other clearing corporation,
as applicable) the appropriate instruction form for exercise, complying with the procedures to effect exercise that are required by the
Depositary (or such other clearing corporation, as applicable). The Company acknowledges that the bank accounts maintained by the Warrant
Agent in connection with the services provided under this Agreement will be in its name and that the Warrant Agent may receive investment
earnings in connection with the investment at Warrant Agent risk and for its benefit of funds held in those accounts from time to time.
Neither the Company nor the Holders will receive interest on any deposits or Exercise Price. 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 be required. The
Company hereby acknowledges and agrees that, with respect to a holder whose interest in a Global Warrant is a beneficial interest in a
Global Warrant held in book-entry form through the Depositary (or another established clearing corporation performing similar functions),
upon delivery of irrevocable instructions to such holder’s Participant to exercise such warrants, that solely for purposes of Regulation
SHO that such holder shall be deemed to have exercised such warrants.

 

    5 

     

    

 

(b) Upon receipt of a
Notice of Exercise for a Cashless Exercise the Company will promptly calculate and transmit to the Warrant Agent the number of Warrant
Shares issuable in connection with such Cashless Exercise and deliver a copy of the Notice of Exercise to the Warrant Agent, which shall
issue such number of Warrant Shares in connection with such Cashless Exercise.

 

(c) Upon the exercise
of the Warrant Certificate pursuant to the terms of Section 2 of the Warrant Certificate, the Warrant Agent shall cause the Warrant
Shares underlying such Warrant Certificate or Global Warrant to be delivered to or upon the order of the Holder of such Warrant Certificate
or Global Warrant, registered in such name or names as may be designated by such Holder, no later than the Warrant Share Delivery Date
(as such term is defined in the Warrant Certificate). If the Company is then a participant in the DWAC system of the Depositary and either
(A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares
by Holder or (B) the Warrant is being exercised via Cashless Exercise, then the certificates for Warrant Shares shall be transmitted
by the Warrant Agent to the Holder by crediting the account of the Holder’s broker with the Depositary through its DWAC system.
For the avoidance of doubt, if the Company becomes obligated to pay any amounts to any Holders pursuant to Section 2(d)(i) or
2(d)(iv) of the Warrant Certificate, such obligation shall be solely that of the Company and not that of the Warrant Agent. Notwithstanding
anything else to the contrary in this Agreement, except in the case of a Cashless Exercise, if any Holder fails to duly deliver payment
to the Warrant Agent of an amount equal to the aggregate Exercise Price of the Warrant Shares to be purchased upon exercise of such Holder’s
Warrant as set forth in Section 7(a) hereof by the Warrant Share Delivery Date, the Warrant Agent will not obligated to deliver
such Warrant Shares (via DWAC or otherwise) until following receipt of such payment, and the applicable Warrant Share Delivery Date shall
be deemed extended by one day for each day (or part thereof) until such payment is delivered to the Warrant Agent.

 

(d) The Warrant Agent
shall deposit all funds received by it in payment of the Exercise Price for all Warrants in the account of the Company maintained with
the Warrant Agent for such purpose (or to such other account as directed by the Company in writing) and shall advise the Company via email
at the end of each day on which notices of exercise are received or funds for the exercise of any Warrant are received of the amount so
deposited to its account.

 

Section 8. Cancellation
and Destruction of Warrant Certificates. All Warrant Certificates surrendered for the purpose of exercise, transfer, split up, combination
or exchange shall, if surrendered to the Company or to any of its agents, be delivered to the Warrant Agent for cancellation or in canceled
form, or, if surrendered to the Warrant Agent, shall be canceled by it, and no Warrant Certificate shall be issued in lieu thereof except
as expressly permitted by any of the provisions of this Agreement. The Company shall deliver to the Warrant Agent for cancellation and
retirement, and the Warrant Agent shall so cancel and retire, any other Warrant Certificate purchased or acquired by the Company otherwise
than upon the exercise thereof. The Warrant Agent shall deliver all canceled Warrant Certificates to the Company, or shall, at the written
request of the Company, destroy such canceled Warrant Certificates, and in such case shall deliver a certificate of destruction thereof
to the Company, subject to any applicable law, rule or regulation requiring the Warrant Agent to retain such canceled certificates.

 

Section 9. Certain
Representations; Reservation and Availability of Shares of Common Stock or Cash.

 

(a) This Agreement has
been duly authorized, executed and delivered by the Company and, assuming due authorization, execution and delivery hereof by the Warrant
Agent, constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms,
and the Warrants have been duly authorized, executed and issued by the Company and, assuming due authentication thereof by the Warrant
Agent pursuant hereto and payment therefor by the Holders as provided in the Registration Statement, constitute valid and legally binding
obligations of the Company enforceable against the Company in accordance with their terms and entitled to the benefits hereof; in each
case except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to
or affecting creditors’ rights generally or by general equitable principles (regardless of whether such enforceability is considered
in a proceeding in equity or at law).

 

    6 

     

    

 

(b) As of the date hereof,
the authorized capital stock of the Company consists of (i) [ ] ([ ],000,000) shares of common stock, of which approximately [ ]
shares of Common Stock are issued and outstanding as of ____, 2021, and [ ] shares of Common Stock are reserved for issuance upon exercise
of the Warrants, and (ii) [ ] million ([ ],000,000) shares of preferred stock, par value $0.001 per share, of which no shares are
issued and outstanding. Except as disclosed in the Registration Statement, there are no other outstanding obligations, warrants, options
or other rights to subscribe for or purchase from the Company any class of capital stock of the Company.

 

(c) The Company covenants
and agrees that it will cause to be reserved and kept available out of its authorized and unissued shares of Common Stock or its authorized
and issued shares of Common Stock held in its treasury, free from preemptive rights, the number of shares of Common Stock that will be
sufficient to permit the exercise in full of all outstanding Warrants.

 

(d) The Warrant Agent
will create a special account for the issuance of Common Stock upon the exercise of Warrants.

 

(e) The Company further
covenants and agrees that it will pay when due and payable any and all federal and state transfer taxes and charges which may be payable
in respect of the original issuance or delivery of the Warrant Certificates or certificates evidencing Common Stock upon exercise of the
Warrants. The Company shall not, however, be required to pay any tax or governmental charge which may be payable in respect of any transfer
involved in the transfer or delivery of Warrant Certificates or the issuance or delivery of certificates for Common Stock in a name other
than that of the Holder of the Warrant Certificate evidencing Warrants surrendered for exercise or to issue or deliver any certificate
for shares of Common Stock upon the exercise of any Warrants until any such tax or governmental charge shall have been paid (any such
tax or governmental charge being payable by the Holder of such Warrant Certificate at the time of surrender) or until it has been established
to the Company’s reasonable satisfaction that no such tax or governmental charge is due.

 

Section 10. Common
Stock Record Date. Each Person in whose name any certificate for shares of Common Stock is issued (or to whose broker’s account
is credited shares of Common Stock through the DWAC system) upon the exercise of Warrants shall for all purposes be deemed to have become
the holder of record for the Common Stock represented thereby on, and such certificate shall be dated, the date on which submission of
the Notice of Exercise was made, provided that the Warrant Certificate evidencing such Warrant is duly surrendered (but only if required
herein) and payment of the Exercise Price (and any applicable transfer taxes) is received on or prior to the Warrant Share Delivery Date;
provided, however, that if the date of submission of the Notice of Exercise is a date upon which the Common Stock transfer
books of the Company are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate
shall be dated, the next succeeding day on which the Common Stock transfer books of the Company are open.

 

Section 11. Adjustment
of Exercise Price, Number of Shares of Common Stock or Number of the Company Warrants. The Exercise Price, the number of shares covered
by each Warrant and the number of Warrants outstanding are subject to adjustment from time to time as provided in Section 3 of the
Warrant Certificate. In the event that at any time, as a result of an adjustment made pursuant to Section 3 of the Warrant Certificate,
the Holder of any Warrant thereafter exercised shall become entitled to receive any shares of capital stock of the Company other than
shares of Common Stock, thereafter the number of such other shares so receivable upon exercise of any Warrant shall be subject to adjustment
from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the shares contained
in Section 3 of the Warrant Certificate and the provisions of Sections 7, 11 and 12 of this Agreement with respect to the shares
of Common Stock shall apply on like terms to any such other shares. All Warrants originally issued by the Company subsequent to any adjustment
made to the Exercise Price pursuant to the Warrant Certificate shall evidence the right to purchase, at the adjusted Exercise Price, the
number of shares of Common Stock purchasable from time to time hereunder upon exercise of the Warrants, all subject to further adjustment
as provided herein.

 

    7 

     

    

 

Section 12. Certification
of Adjusted Exercise Price or Number of Shares of Common Stock. Whenever the Exercise Price or the number of shares of Common Stock
issuable upon the exercise of each Warrant is adjusted as provided in Section 11 or 13, the Company shall (a) promptly prepare
a certificate setting forth the Exercise Price of each Warrant as so adjusted, and a brief statement of the facts accounting for such
adjustment, (b) promptly file with the Warrant Agent and with each transfer agent for the Common Stock a copy of such certificate
and (c) instruct the Warrant Agent to send a brief summary thereof to each Holder of a Warrant Certificate.

 

Section 13. Fractional
Shares of Common Stock.

 

(a) The Company shall
not issue fractions of Warrants or distribute Warrant Certificates which evidence fractional Warrants. Whenever any fractional Warrant
would otherwise be required to be issued or distributed, the actual issuance or distribution shall reflect a rounding of such fraction
to the nearest whole Warrant (rounded down).

 

(b) The Company shall
not issue fractions of shares of Common Stock upon exercise of Warrants or distribute stock certificates which evidence fractional shares
of Common Stock. Whenever any fraction of a share of Common Stock would otherwise be required to be issued or distributed, the actual
issuance or distribution in respect thereof shall be made in accordance with Section 2(d)(v) of the Warrant Certificate.

 

Section 14. Conditions
of the Warrant Agent’s Obligations. The Warrant Agent accepts its obligations herein set forth upon the terms and conditions
hereof, including the following to all of which the Company agrees and to all of which the rights hereunder of the Holders from time to
time of the Warrant Certificates shall be subject:

 

		(a)	Compensation and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation
detailed on Exhibit 4 hereto for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable
out-of-pocket expenses (including reasonable counsel fees) incurred without gross negligence or willful misconduct finally adjudicated
to have been directly caused by the Warrant Agent in connection with the services rendered hereunder by the Warrant Agent. The Company
also agrees to indemnify the Warrant Agent for, and to hold it harmless against, any loss, liability or expense incurred without gross
negligence, or willful misconduct on the part of the Warrant Agent, finally adjudicated to have been directly caused by Warrant Agent
hereunder, including the reasonable costs and expenses of defending against any claim of such liability. The Warrant Agent shall be under
no obligation to institute or defend any action, suit, or legal proceeding in connection herewith or to take any other action likely to
involve the Warrant Agent in expense, unless first indemnified to the Warrant Agent’s satisfaction. The indemnities provided by
this paragraph shall survive the resignation or discharge of the Warrant Agent or the termination of this Agreement. Anything in this
Agreement to the contrary notwithstanding, in no event shall the Warrant Agent be liable under or in connection with the Agreement for
indirect, special, incidental, punitive or consequential losses or damages of any kind whatsoever, including but not limited to lost profits,
whether or not foreseeable, even if the Warrant Agent has been advised of the possibility thereof and regardless of the form of action
in which such damages are sought, and the Warrant Agent’s aggregate liability to the Company, or any of the Company’s representatives
or agents, under this Section 14(a) or under any other term or provision of this Agreement, whether in contract, tort, or otherwise,
is expressly limited to, and shall not exceed in any circumstances, one (1) year’s fees received by the Warrant Agent as fees
and charges under this Agreement, but not including reimbursable expenses previously reimbursed to the Warrant Agent by the Company hereunder.

 

		(b)	Agent for the Company. In acting under this Warrant Agreement and in connection with the Warrant
Certificates, the Warrant Agent is acting solely as agent of the Company and does not assume any obligations or relationship of agency
or trust for or with any of the Holders of Warrant Certificates or beneficial owners of Warrants.

 

    8 

     

    

 

		(c)	Counsel. The Warrant Agent may consult with counsel satisfactory to it, which may include counsel
for the Company, and the written advice of such counsel shall be full and complete authorization and protection in respect of any action
taken, suffered or omitted by it hereunder in good faith and in accordance with the advice of such counsel.

 

		(d)	Documents. The Warrant Agent shall be protected and shall incur no liability for or in respect
of any action taken or omitted by it in reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement
or other paper or document reasonably believed by it to be genuine and to have been presented or signed by the proper parties.

 

		(e)	Certain Transactions. The Warrant Agent, and its officers, directors and employees, may become
the owner of, or acquire any interest in, Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder,
and, to the extent permitted by applicable law, it or they may engage or be interested in any financial or other transaction with the
Company and may act on, or as depositary, trustee or agent for, any committee or body of Holders of Warrant Securities or other obligations
of the Company as freely as if it were not the Warrant Agent hereunder. Nothing in this Warrant Agreement shall be deemed to prevent the
Warrant Agent from acting as trustee under any indenture to which the Company is a party.

 

		(f)	No Liability for Interest. Unless otherwise agreed with the Company, the Warrant Agent shall have
no liability for interest on any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant
Certificates.

 

		(g)	No Liability for Invalidity. The Warrant Agent shall have no liability with respect to any invalidity
of this Agreement or the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon).

 

		(h)	No Responsibility for Representations. The Warrant Agent shall not be responsible for any of the
recitals or representations herein or in the Warrant Certificate (except as to the Warrant Agent’s countersignature thereon), all
of which are made solely by the Company.

 

		(i)	No Implied Obligations. The Warrant Agent shall be obligated to perform only such duties as are
herein and in the Warrant Certificates specifically set forth and no implied duties or obligations shall be read into this Agreement or
the Warrant Certificates against the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action hereunder which
may tend to involve it in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured
to it. The Warrant Agent shall not be accountable or under any duty or responsibility for the use by the Company of any of the Warrant
Certificates authenticated by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or for the application by
the Company of the proceeds of the Warrant Certificate. The Warrant Agent shall have no duty or responsibility in case of any default
by the Company in the performance of its covenants or agreements contained herein or in the Warrant Certificates or in the case of the
receipt of any written demand from a Holder of a Warrant Certificate with respect to such default, including, without limiting the generality
of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law.

 

Section 15. Purchase
or Consolidation or Change of Name of Warrant Agent. Any corporation into which the Warrant Agent or any successor Warrant Agent may
be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Warrant Agent
or any successor Warrant Agent shall be party, or any corporation succeeding to the corporate trust business of the Warrant Agent or any
successor Warrant Agent, shall be the successor to the Warrant Agent under this Agreement without the execution or filing of any paper
or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor
Warrant Agent under the provisions of Section 17. In case at the time such successor Warrant Agent shall succeed to the agency created
by this Agreement any of the Warrant Certificates shall have been countersigned but not delivered, any such successor Warrant Agent may
adopt the countersignature of the predecessor Warrant Agent and deliver such Warrant Certificates so countersigned; and in case at that
time any of the Warrant Certificates shall not have been countersigned, any successor Warrant Agent may countersign such Warrant Certificates
either in the name of the predecessor Warrant Agent or in the name of the successor Warrant Agent; and in all such cases such Warrant
Certificates shall have the full force provided in the Warrant Certificates and in this Agreement.

 

    9 

     

    

 

In case at any time the name
of the Warrant Agent shall be changed and at such time any of the Warrant Certificates shall have been countersigned but not delivered,
the Warrant Agent may adopt the countersignature under its prior name and deliver such Warrant Certificates so countersigned; and in case
at that time any of the Warrant Certificates shall not have been countersigned, the Warrant Agent may countersign such Warrant Certificates
either in its prior name or in its changed name; and in all such cases such Warrant Certificates shall have the full force provided in
the Warrant Certificates and in this Agreement.

 

Section 16. Duties
of Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions,
by all of which the Company, by its acceptance hereof, shall be bound:

 

(a) The Warrant Agent
may consult with legal counsel reasonably acceptable to the Company (who may be legal counsel for the Company), and the opinion of such
counsel shall be full and complete authorization and protection to the Warrant Agent as to any action taken or omitted by it in good faith
and in accordance with such opinion.

 

(b) Whenever in the performance
of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established
by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein
specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by the Chief Executive Officer,
Chief Financial Officer or Vice President of the Company; and such certificate shall be full authentication to the Warrant Agent for any
action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

 

(c) Subject to the limitation
set forth in Section 14, the Warrant Agent shall be liable hereunder only for its own gross negligence or willful misconduct, or
for a breach by it of this Agreement.

 

(d) The Warrant Agent
shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the Warrant Certificate
(except its countersignature thereof) by the Company or be required to verify the same, but all such statements and recitals are and shall
be deemed to have been made by the Company only.

 

(e) The Warrant Agent
shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due
execution hereof by the Warrant Agent) or in respect of the validity or execution of any Warrant Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any
Warrant Certificate; nor shall it be responsible for the adjustment of the Exercise Price or the making of any change in the number of
shares of Common Stock required under the provisions of Section 11 or 13 or responsible for the manner, method or amount of any such
change or the ascertaining of the existence of facts that would require any such adjustment or change (except with respect to the exercise
of Warrants evidenced by the Warrant Certificates after actual notice of any adjustment of the Exercise Price); nor shall it by any act
hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be
issued pursuant to this Agreement or any Warrant Certificate or as to whether any shares of Common Stock will, when issued, be duly authorized,
validly issued, fully paid and nonassessable.

 

(f) Each party hereto
agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such
further and other acts, instruments and assurances as may reasonably be required by the other party hereto for the carrying out or performing
by any party of the provisions of this Agreement.

(g) The Warrant Agent
is hereby authorized to accept instructions with respect to the performance of its duties hereunder from the Chief Executive Officer,
Chief Financial Officer or Vice President of the Company, and to apply to such officers for advice or instructions in connection with
its duties, and it shall not be liable and shall be indemnified and held harmless for any action taken or suffered to be taken by it in
good faith in accordance with instructions of any such officer, provided Warrant Agent carries out such instructions without gross negligence
or willful misconduct.

 

(h) The Warrant Agent
and any shareholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrants or other securities
of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money
to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein shall preclude
the Warrant Agent from acting in any other capacity for the Company or for any other legal entity.

 

(i) The Warrant Agent
may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through
its attorney or agents, and the Warrant Agent shall not be answerable or accountable for any act, default, neglect or misconduct of any
such attorney or agents or for any loss to the Company resulting from any such act, default, neglect or misconduct, provided reasonable
care was exercised in the selection and continued employment thereof.

 

Section 17. Change
of Warrant Agent. The Warrant Agent may resign and be discharged from its duties under this Agreement upon 30 days’ notice in
writing sent to the Company and to each transfer agent of the Common Stock, and to the Holders of the Warrant Certificates. The Company
may remove the Warrant Agent or any successor Warrant Agent upon 30 days’ notice in writing, sent to the Warrant Agent or successor
Warrant Agent, as the case may be, and to each transfer agent of the Common Stock, and to the Holders of the Warrant Certificates. If
the Warrant Agent shall resign or be removed or shall otherwise become incapable of acting, the Company shall appoint a successor to the
Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after such removal or after it has been notified
in writing of such resignation or incapacity by the resigning or incapacitated Warrant Agent or by the Holder of a Warrant Certificate
(who shall, with such notice, submit his Warrant Certificate for inspection by the Company), then the Holder of any Warrant Certificate
may apply to any court of competent jurisdiction for the appointment of a new Warrant Agent, provided that, for purposes of this Agreement,
the Company shall be deemed to be the Warrant Agent until a new warrant agent is appointed. Any successor Warrant Agent, whether appointed
by the Company or by such a court, shall be a corporation organized and doing business under the laws of the United States or of a state
thereof, in good standing, which is authorized under such laws to exercise corporate trust powers and is subject to supervision or examination
by federal or state authority and which has at the time of its appointment as Warrant Agent a combined capital and surplus of at least
$50,000,000. After appointment, the successor Warrant Agent shall be vested with the same powers, rights, duties and responsibilities
as if it had been originally named as Warrant Agent without further act or deed; but the predecessor Warrant Agent shall deliver and transfer
to the successor Warrant Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance,
act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Company shall file notice thereof
in writing with the predecessor Warrant Agent and each transfer agent of the Common Stock, and mail a notice thereof in writing to the
Holders of the Warrant Certificates. However, failure to give any notice provided for in this Section 17, or any defect therein,
shall not affect the legality or validity of the resignation or removal of the Warrant Agent or the appointment of the successor Warrant
Agent, as the case may be.

 

Section 18. Issuance
of New Warrant Certificates. Notwithstanding any of the provisions of this Agreement or of the Warrants to the contrary, the Company
may, at its option, issue new Warrant Certificates evidencing Warrants in such form as may be approved by its Board of Directors to reflect
any adjustment or change in the Exercise Price per share and the number or kind or class of shares of stock or other securities or property
purchasable under the several Warrant Certificates made in accordance with the provisions of this Agreement.

 

Section 19. Notices.
Notices or demands authorized by this Agreement to be given or made (i) by the Warrant Agent or by the Holder of any Warrant Certificate

given if given to the Depositary (or its designee) pursuant to the procedures of the Depositary or its designee.

of Common Stock issuable thereunder, the Company and the Warrant Agent may modify this Agreement for the purpose of adding any provisions
to or changing in any manner or eliminating any of the provisions of this Warrant Agreement or modifying in any manner the rights of the
Holders of the Global Warrants; provided, however, that no modification of the terms (including but not limited to the adjustments
described in Section 11) upon which the Warrants are exercisable or the rights of holders of Warrants to receive liquidated damages
or other payments in cash from the Company or reducing the percentage required for consent to modification of this Agreement may be made
without the consent of the Holder of each outstanding Warrant Certificate affected thereby; provided further, however, that
no amendment hereunder shall affect any terms of any Warrant Certificate issued in a Warrant Exchange. As a condition precedent to the
Warrant Agent’s execution of any amendment, the Company shall deliver to the Warrant Agent a certificate from a duly authorized
officer of the Company that states that the proposed amendment complies with the terms of this Section 20.

or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of a duly executed facsimile copy
(or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”). Within the
earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined
in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price
for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank
unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of Exercise. 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 be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender
this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised
in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of
the date on which the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases of
a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant
Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall
maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection
to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of
this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant
Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on
the face hereof.

 

Notwithstanding the foregoing in this
Section 2(a), a holder whose interest in this Warrant is a beneficial interest in certificate(s) representing this Warrant held
in book-entry form through DTC (or another established clearing corporation performing similar functions), shall effect exercises made
pursuant to this Section 2(a) by delivering to DTC (or such other clearing corporation, as applicable) the appropriate instruction
form for exercise, complying with the procedures to effect exercise that are required by DTC (or such other clearing corporation, as applicable),
subject to a Holder’s right to elect to receive a Definitive Warrant pursuant to the terms of the Warrant Agency Agreement, in which
case this sentence shall not apply.

 

    2

     

    

 

b)       Exercise
Price. The exercise price per share of Common Stock under this Warrant shall be $_____1, subject to adjustment hereunder
(the “Exercise Price”).

 

c)        Cashless
Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained
therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may also be exercised, in whole or in
part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant
Shares equal to the quotient obtained by dividing ((A-B)(X)) by (A), where:

 

(A) = as applicable:
(i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is
(1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed
and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as
defined in Rule 600(b) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the
option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise
or (z) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s
execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a
Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular
trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable
Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered
pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;

 

(B) = the
Exercise Price of this Warrant, as adjusted hereunder; and

 

(X) =
the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such
exercise were by means of a cash exercise rather than a cashless exercise. 

If Warrant Shares
are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities
Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to take any
position contrary to this Section 2(c).

 

d)           Mechanics
of Exercise.

 

		i.	Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased
hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s
balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if
the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance
of the Warrant Shares to or resale of the Warrant Shares by Holder or (B) this Warrant is being exercised via cashless exercise,
and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its
designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder
in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company of
the Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company and (iii) the
number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise (such date,
the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate
purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective
of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless
exercise) is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the
Standard Settlement Period following delivery of the Notice of Exercise. If the Company fails for any reason to deliver to the Holder
the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as
liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock
on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading Day after
such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered
or Holder rescinds such exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as
this Warrant remains outstanding and exercisable. 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 Stock as in effect
on the date of delivery of the Notice of Exercise.

ii.            Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and
upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing
the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects
be identical with this Warrant.

 

iii.           Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by
the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

 

iv.           Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if
the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance with the provisions of Section 2(d)(i) above
pursuant to an exercise on or before the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase
(in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver
in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price
(including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying
(1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue
times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the
Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in
which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been
issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common
Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with
an aggregate sale price giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence
the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable
to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit
a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree
of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock
upon exercise of the Warrant as required pursuant to the terms hereof.

 

    4

     

    

 

v.            No
Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall,
at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the
Exercise Price or round up to the next whole share.

 

vi.            Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant
Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require, as
a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all
Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another
established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

 

vii.          Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

 

    5

     

    

 

e)        Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise
any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise
as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other Persons acting
as a group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would
beneficially own in excess of the Beneficial Ownership Limitation (as defined below).  For purposes of the foregoing sentence, the
number of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number
of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude
the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant
beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised
or nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject
to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its
Affiliates or Attribution Parties.  Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial
ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance
with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance
therewith. To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant
is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution Parties) and of which
portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall
be deemed to be the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the
Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case subject
to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of such determination.
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 2(e), in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the
Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement
by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common
Stock outstanding.  Upon the written or oral request of a Holder, the Company shall within one Trading Day confirm orally and in
writing to the Holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares of Common
Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the
Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported.
The “Beneficial Ownership Limitation” shall be 4.99% (or, upon election by a Holder prior to the issuance of any Warrants,
9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock
issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation
provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares
of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant
held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership
Limitation will not be effective until the 61st day after such notice is delivered to the Company. The provisions of this paragraph
shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct
this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein
contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained
in this paragraph shall apply to a successor holder of this Warrant.

Section 3.          Certain
Adjustments.

 

a)     Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes
a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of
Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this
Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way
of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification of
shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before
such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the
number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this
Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the
record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately
after the effective date in the case of a subdivision, combination or re-classification.

 

b)     Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders
of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon
the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held
the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise
hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for
the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares
of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the
Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation,
then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of
Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for
the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

 

c)     Pro
Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution
of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a "Distribution"), at any time after the
issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent
that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete
exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership
Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as
of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided,
however, to the extent that the Holder's right to participate in any such Distribution would result in the Holder exceeding the
Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the
beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution
shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder
exceeding the Beneficial Ownership Limitation).

 

    7

     

    

 

d)     Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more
related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or
indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its
assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer
(whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange
their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common Stock,
(iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization
of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for
other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions consummates a
stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off
or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding
shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated
or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each a
 “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to
receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental
Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant),
the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation,
and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction
by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction
(without regard to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination
of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among
the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration.
If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then
the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such
Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor
(the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant in accordance
with the provisions of this Section 3(e) pursuant to written agreements in form and substance reasonably satisfactory to the
Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder,
deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor
Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without
regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies
the exercise price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock
pursuant to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such
exercise price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental
Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions
of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and
power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect as if such Successor
Entity had been named as the Company herein.

 

    8

     

    

 

e)     Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For
purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be
the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

 

f)     Notice
to Holder.

 

i.            Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment
to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

 

ii.            Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the
Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of
capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all
or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities,
cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs
of the Company, then, in each case, the Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile
number or email address as it shall appear upon the Warrant Register of the Company, at least 20 calendar days prior to the applicable
record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the
Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the
date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close,
and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common
Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange;
provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the
corporate action required to be specified in such notice. To the extent that any notice provided in this Warrant constitutes, or contains,
material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with
the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period
commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set
forth herein.

 

    9

     

    

 

Section 4.         Transfer
of Warrant.

 

a)    Transferability.
This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part,
upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute
and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations
specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so
assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required
to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall
surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers an assignment form to
the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder
for the purchase of Warrant Shares without having a new Warrant issued.

 

b)    New
Warrants. If this Warrant is not held in global form through DTC (or any successor depositary), this Warrant may be divided or combined
with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names
and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a),
as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants
in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or
exchanges shall be dated the initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of
Warrant Shares issuable pursuant thereto.

 

c)    Warrant
Register. The Warrant Agent (or, in the event a Holder elects to receive a Definitive Certificate (as defined in the Warrant Agency
Agreement), the Company) shall register this Warrant, upon records to be maintained by the Warrant Agent (or, in the event a Holder elects
to receive a Definitive Certificate, the Company) for that purpose (the “Warrant Register”), in the name of the record
Holder hereof from time to time. The Company and the Warrant Agent may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice
to the contrary.

 

Section 5.          Miscellaneous.

 

a)    No
Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly
set forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares on a “cashless exercise” pursuant
to Section 2(c) or to receive cash payments pursuant to Section 2(d)(i) and Section 2(d)(iv) herein, in
no event shall the Company be required to net cash settle an exercise of this Warrant.

 

    10

     

    

 

b)    Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include
the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make
and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

 

c)     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.

 

d)    Authorized
Shares.

 

The Company covenants
that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number
of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further
covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the
necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action
as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation,
or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented
by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable
and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any
transfer occurring contemporaneously with such issue).

 

Except and to the
extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate
of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate
to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the
Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately
prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable
efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may
be, necessary to enable the Company to perform its obligations under this Warrant.

 

Before taking any
action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price,
the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

 

    11

     

    

 

e)     Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant 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 Warrant (whether brought against a party hereto or their 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, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of any such court, that such suit, 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 suit, 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 Warrant 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 either party shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing
party in such action, suit or proceeding shall be reimbursed by the other party for their reasonable attorneys’ fees and other
costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding.

 

f)     Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does not
utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

 

g)    Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver
of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant,
if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the
Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs and expenses including, but not limited
to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due
pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

 

h)    Notices.
Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without limitation, any Notice
of Exercise, shall be in writing and delivered personally, or e-mail, or sent by a nationally recognized overnight courier service, addressed
to the Company, at 2150 Cabot Boulevard West, Suite B, Langhorne, Pennsylvania 19067, Attention: Adam Levy, email address: alevy@nexgel.com,
or such other facsimile number, email address or address as the Company may specify for such purposes by notice to the Holders. Any and
all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally,
by facsimile or e-mail, or sent by a nationally recognized overnight courier service addressed to each Holder at the facsimile number,
e-mail address or address of such Holder appearing on the books of the Company. Any notice or other communication or deliveries hereunder
shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section prior to 5:30 p.m. (New
York City time) on any date, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile number or via e-mail at the e-mail address set forth in this Section on a day that is not a Trading
Day or later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing,
if sent by U.S. nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom such notice is
required to be given. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding
the Company or any subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on
Form 8-K.

 

    12

     

    

 

i)     Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the
Company.

 

j)     Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific
performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any
action for specific performance that a remedy at law would be adequate.

 

k)     Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder.
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable
by the Holder or holder of Warrant Shares.

 

l)     Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company, on the one hand, and
the Holder or the beneficial owner of this Warrant, on the other hand.

 

m)   Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the
extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

 

n)    Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

 

o)    Warrant
Agency Agreement. If this Warrant is held in global form through DTC (or any successor depositary), this Warrant is issued subject to
the Warrant Agency Agreement. To the extent any provision of this Warrant conflicts with the express provisions of the Warrant Agency
Agreement, the provisions of this Warrant shall govern and be controlling.

 

IN WITNESS WHEREOF, the Company
has caused this Warrant to be executed by its officer thereunto duly authorized as of the date first above indicated.
