Warrant (and all securities issued in exchange therefor or substitution thereof, except any shares of Common Stock issued upon
exercise thereof) that bears, or that is required under this Section 2.04 to bear, the Restricted Warrants Legend, will be deemed
to be a “Restricted Warrant.” Each Restricted Warrant will be subject to the restrictions on transfer set forth
in this Warrant Agreement (including in the Restricted Warrants Legend) and will bear the restricted CUSIP number for the Warrants
unless such restrictions on transfer are eliminated or otherwise waived by written consent of the Company, and each Warrantholder

restrictions on transfer applicable to such Restricted Warrant.

 

    	 	10	 

     

    

 

(ii)         Until
the Resale Restriction Termination Date, the Warrants may not be reoffered, sold, assigned, transferred, pledged, encumbered or
otherwise disposed of by a Warrantholder except (A) pursuant to a registration statement that has become effective under the Securities
Act or (B) pursuant to an exemption from the registration requirements of the Securities Act, including Rule 144 under the Securities
Act.

 

(iii)        In
addition, until the Resale Restriction Termination Date, any Warrant that is purchased or owned by the Company or any “affiliate”
thereof (as defined under Rule 144 under the Securities Act) may not be resold by the Company or such affiliate unless registered
under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction
that results in such Warrants no longer being “restricted securities” (as defined in Rule 144 under the Securities
Act).

 

(iv)        On
and after the Resale Restriction Termination Date, any Warrant (or any security issued in exchange therefor or substitution thereof,
except any shares of Common Stock issued upon the exercise thereof) will bear the Restricted Warrants Legend at any time the Company
reasonably determinates that, to comply with law, such Warrant (or such securities issued in exchange for or substitution of a
Warrant) must bear the Restricted Warrants Legend.

Common Stock.

 

(i)          Every

to be “Restricted Stock.” Each share of Restricted Stock will be subject to the restrictions on transfer set
forth in this Warrant Agreement and will bear a restricted CUSIP number unless such restrictions on transfer are eliminated or
otherwise waived by written consent of the Company, and each Warrantholder of Restricted Stock, by such Warrantholder’s acceptance
of Restricted Stock, will be deemed to be bound by the restrictions on transfer applicable to such Restricted Stock.

 

(ii)         Until
the Resale Restriction Termination Date, the shares of Common Stock issued to a Warrantholder upon exercise of a Warrant may not
be reoffered, sold, assigned, transferred, pledged, encumbered or otherwise disposed of by such Warrantholder except (A) pursuant

Restricted Stock Legend at any time the Company reasonably determinates that, to comply with law, such share of Common Stock must
bear the Restricted Stock Legend, but shall not otherwise bear the Restricted Stock Legend; provided, however, that in connection
with any sale, assignment or transfer of any shares of Common Stock that are eligible to be sold, assigned or transferred under
Rule 144, it shall be sufficient for the Warrantholder of such Common Stock to provide the Company with reasonable assurances that
such Common Stock are eligible for sale, assignment or transfer under Rule 144 and will be resold prior to the filing of the earliest
of the Company’s next Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as applicable, and need not provide an
opinion of such Warrantholder’s counsel.

 

Section 2.05.         Registration
of Transfer, Exchange and Substitution. (a) The Company shall cause to be kept at the office of the Warrant Agent, and the
Warrant Agent shall maintain, a register (the “Warrant Register”) in which, subject to such reasonable regulations
as the Company may prescribe, the Company shall provide for the registration of Warrants and transfers, exchanges or substitutions
of Warrants as herein provided. The Warrant Agent his hereby appointed “Registrar” (the “Registrar”)
for the purpose of registering Warrants and transfers of Warrants as herein provided. All Warrants issued upon any registration
of transfer or exchange of or substitution for Warrants shall be valid obligations of the Company, evidencing the same obligations,
and entitled to the same benefits under this Warrant Agreement, as Warrants surrendered for such registration of transfer, exchange
or substitution.

 

(b)          A
Warrantholder may transfer a Warrant only upon surrender of such Warrant for registration of transfer. Warrants may be presented
for registration of transfer and exchange at the offices of the Warrant Agent with a written instruction of transfer in the form
annexed to Exhibit D hereto, duly executed by such Warrantholder or by such Warrantholder’s attorney, duly authorized in
writing. Such Warrantholder will also provide a written certificate (substantially in the form of Exhibit E hereto) to the effect
that such transfer will comply with the appropriate transfer restrictions applicable to such Warrants. The Warrant Agent shall
be entitled to conclusively rely upon any such certification in connection with the transfer of a Warrant hereunder and shall have
no responsibility to monitor or verify whether any such transfer complies with the requirements hereunder or otherwise complies
with the Securities Act. No such transfer shall be effected until, and the transferee shall succeed to the rights of a Warrantholder
only upon, final acceptance and registration of the transfer in the Warrant Register by the Warrant Agent. Prior to the registration
of any transfer of a Warrant by a Warrantholder as provided herein, the Company, the Warrant Agent, and any agent of the Company
or the Warrant Agent may treat the Person in whose name Warrants are registered as the owner thereof for all purposes and as the
Person entitled to exercise the rights represented thereby, any notice to the contrary notwithstanding.

 

(c)          Every
Warrant presented or surrendered for registration of transfer or for exchange or substitution shall (if so required by the Company
or the Warrant Agent) be duly endorsed, or be accompanied by a duly executed instrument of transfer in form satisfactory to the
Company and the Warrant Agent, by the holder thereof or such Warrantholder’s attorney duly authorized in writing.

 

    	 	12	 

     

    

 

(d)          When
Warrants are presented to the Warrant Agent with a request to register the transfer of, or to exchange or substitute, such Warrants,
the Warrant Agent shall register the transfer or make the exchange or substitution as requested if its requirements for such transactions
and any applicable requirements hereunder are satisfied. To permit registrations of transfers, exchanges and substitutions, the
Company shall execute Warrant Certificates at the Warrant Agent’s request and the Warrant Agent, upon receipt of an Authentication
Order, shall countersign and deliver such Warrant Certificates. No service charge shall be made for any registration of transfer
or exchange of or substitution for Warrants, but the Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of transfer of Warrants.

 

Section 2.06.         Global
Warrants.

 

(a)          Any
Global Warrant shall bear the legend substantially in the form set forth in Exhibit C hereto (the “Global Warrant Legend”).

 

(b)          So
long as a Global Warrant is registered in the name of the Depositary or its nominee, members of, or participants in, the Depositary
(“Agent Members”) shall have no rights under this Warrant Agreement with respect to the Global Warrant held
on their behalf by the Depositary or the Warrant Agent as its custodian, and the Depositary may be treated by the Company, the
Warrant Agent and any agent of the Company or the Warrant Agent as the absolute owner of such Global Warrant for all purposes.
Accordingly, any such owner’s beneficial interest in such Global Warrant will be shown only on, and the transfer of such
interest shall be effected only through, records maintained by the Depositary or its nominee or its Agent Members, and neither
the Company nor the Warrant Agent shall have any responsibility with respect to such records maintained by the Depositary or its
nominee or its Agent Members. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Warrant Agent or any
agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished
by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the
exercise of the rights of a Warrantholder.

 

(c)          Any
holder of a Global Warrant registered in the name of the Depositary or its nominee shall, by acceptance of such Global Warrant,
agree that transfers of beneficial interests in such Global Warrant may be effected only through a book-entry system maintained
by the holder of such Global Warrant (or its agent), and that ownership of a beneficial interest in Warrants represented thereby
shall be required to be reflected in book-entry form.

 

(d)          Transfers
of a Global Warrant registered in the name of the Depositary or its nominee shall be limited to transfers in whole, and not in
part, to the Company, the Depositary, their successors, and their respective nominees. Interests of beneficial owners in a Global
Warrant registered in the name of the Depositary or its nominee shall be transferred in accordance with the rules and procedures
of the Depositary.

 

(e)          The
holder of a Global Warrant registered in the name of the Depositary or its nominee may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Warrantholder
is entitled to take under this Warrant Agreement or the Warrant.

 

    	 	13	 

     

    

 

Section 2.07.         Expiration
of Restrictions. 

 

(a)          Any
Warrants as to which such restrictions on transfer shall no longer be applicable in accordance with their terms such that they
can be freely sold without limits under the Securities Act and any applicable state securities law may, upon surrender of the Warrant
Certificates representing such Warrants for exchange pursuant to Section 2.05 in accordance with the procedures of the Warrant
Agent (together with any legal opinions, certifications or other evidence as may reasonably be required by the Company or the Warrant
Agent in order to determine that the proposed transfer is being made in compliance with the Securities Act and applicable state
securities laws), be exchanged for a new Warrant Certificate for a like Number of Warrants, which shall not bear such Restricted
Warrants Legend.

 

(b)          Any
such shares of Common Stock as to which such restrictions on transfer shall no longer be applicable in accordance with their terms
such that the shares of Common Stock can be freely sold without limits under the Securities Act and any applicable state securities
law may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures
of the Transfer Agent (together with any legal opinions, certifications or other evidence as may reasonably be required by the
Company or the Transfer Agent in order to determine that the proposed transfer is being made in compliance with the Securities
Act and applicable state securities laws), be exchanged for a new certificate or certificates for a like number of shares of Common
Stock, which shall not bear such Restricted Stock Legend.

 

(c)          Global
Warrants; Resale Restriction Termination Date.

 

(i)          If,
on the Resale Restriction Termination Date, or the next succeeding Business Day if the Resale Restriction Termination Date is not
a Business Day, any Warrants are represented by a Global Warrant that is a Restricted Warrant (any such Global Warrant, a “Restricted
Global Warrant”), as promptly as practicable, the Company will automatically exchange every beneficial interest in each
Restricted Global Warrant for beneficial interests in Global Warrants that are not subject to the restrictions set forth in the
Restricted Warrants Legend and in Section 2.04 hereof.

 

(ii)         To
effect such automatic exchange, the Company will (A) deliver to the Depositary an instruction letter for the Depositary’s
exchange process at least 15 days immediately prior to the Resale Restriction Termination Date and (B) deliver to each of the Warrant
Agent and the Registrar a duly completed Free Transferability Certificate, promptly after the Resale Restriction Termination Date.

 

(A)         Immediately
upon receipt of the Free Transferability Certificate by each of the Warrant Agent and the Registrar the Restricted Warrants Legend
will be deemed removed from each of the Global Warrants specified in such Free Transferability Certificate and the restricted CUSIP
number will be deemed removed from each of such Global Warrants and deemed replaced with an unrestricted CUSIP number.

 

(B)         Promptly
after the Resale Restriction Termination Date, the Company will provide Bloomberg LLP with a copy of the Free Transferability Certificate
and will use reasonable efforts to cause Bloomberg LLP to adjust its screen page for the Warrants to indicate that the Warrants
are no longer Restricted Warrants and are now identified by an unrestricted CUSIP number.

 

    	 	14	 

     

    

 

(iii)        Prior
to the Company’s delivery of the Free Transferability Certificate and afterwards, the Company and the Warrant Agent will
comply with the Applicable Procedures and the Company will use reasonable efforts to cause each Global Warrant to be identified
by an unrestricted CUSIP number in the facilities of the Depositary by the date the Free Transferability Certificate is delivered
to the Warrant Agent and the Registrar or as promptly as possible thereafter (and the Warrant Agent will reasonably cooperate with
the Company in connection with such efforts).

 

(iv)        Notwithstanding
anything to the contrary in Sections 2.07(c)(i), (ii) and (iii), the Company will not be required to deliver the Free Transferability
Certificate if, in the written opinion of counsel, removal of the Restricted Warrants Legend or the changes to the CUSIP numbers
for the Warrants could result in or facilitate transfers of the Warrants in violation of applicable law.

and Exchange.

 

(a)          Provisions
Applicable to All Transfers and Exchanges.

 

(i)          Subject

or exchanged from time to time as desired, and each such transfer or exchange will be noted by the Registrar in the Warrant Register.

 

(ii)         All
Warrants issued upon any registration of transfer or exchange in accordance with this Warrant Agreement will be the valid obligations
of the Company, evidencing the same equity, and entitled to the same benefits under this Warrant Agreement as the Warrants surrendered
upon such registration of transfer or exchange.

 

(iii)        No
service charge will be imposed on any Warrantholder of a Certificated Warrant or any owner of a beneficial interest in a Global

the Company specifies otherwise, none of the Company, the Warrant Agent, the Registrar or any co-Registrar will be required to
exchange or register a transfer of any Warrant (i) that has been exercised and surrendered or (ii) as to which a notice has been
delivered in connection with a Fundamental Transaction pursuant to Section 4.09(c) and not withdrawn, in each case, except to the
extent any portion of such Warrant is not subject to the foregoing.

 

    	 	15	 

     

    

 

(v)         The
Warrant Agent will have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Warrant Agreement or under applicable law with respect to any transfer of any interest in any Warrant (including
any transfers between or among Depositary participants or beneficial owners of interests in any Global Warrant) other than to require
delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly
required by the terms of, this Warrant Agreement, and to examine the same to determine substantial compliance as to form with the
express requirements hereof.

 

(b)          In

Warrants will be represented by one or more Global Warrants;

 

(ii)         every

(iii)        each
Global Warrant may be transferred only as a whole and only (A) by the Depositary to a nominee of the Depositary, (B) by a nominee
of the Depositary to the Depositary or to another nominee of the Depositary, or (C) by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.

 

(c)          Transfer

(i)          Notwithstanding
any other provision of this Warrant Agreement, each Global Warrant will be exchanged for Certificated Warrants if the Depositary

(A)         the
Depositary is unwilling or unable to continue to act as Depositary; or

 

(B)         the
Depositary is no longer registered as a clearing agency under the Exchange Act;

 

and, in each case, the Company promptly
delivers a copy of such notice to the Warrant Agent and the Company fails to appoint a successor Depositary within 90 days after

a written request to the Registrar.

beneficial interest to be exchanged, the aggregate amount of Warrants of such beneficial interest and the CUSIP of the relevant
Global Warrant; (B) the Company will, in accordance with Section 2.02, promptly execute, and, upon receipt of an Authentication

are required to bear under Section 2.04, and (C) the Registrar, in accordance with the Applicable Procedures, will cause the amount
of Warrants represented by such Global Warrant to be decreased by the aggregate amount of Warrants of the beneficial interest so
exchanged. If all of the beneficial interests in a Global Warrant are so exchanged, such Global Warrant will be deemed surrendered

the Applicable Procedures.

(iii)        If
Certificated Warrants are issued, a Warrantholder may transfer or exchange a Certificated Warrant for a beneficial interest in
a Global Warrant by (A) surrendering such Certificated Warrant for registration of transfer or exchange, together with any endorsements
or instruments of transfer required by any of the Company, the Warrant Agent or the Registrar, at any office or agency maintained
by the Company for such purposes; (B) if such Certificated Warrant is a Restricted Warrant, delivering any documentation the Company,
the Warrant Agent or the Registrar reasonably require to ensure that such transfer complies with Section 2.04 and any applicable
securities laws; (C) satisfying all other requirements for such transfer set forth in this Section 2.08 and Section 2.04; and (D)

such Global Warrant, which instructions will contain information regarding the Depositary account to be credited with such increase.
Upon the satisfaction of conditions (A), (B), (C) and (D), the Warrant Agent will cancel such Certificated Warrant and cause, or
direct the Registrar to cause, in accordance with the Applicable Procedures, the aggregate Number of Warrants represented by such
Global Warrant to be increased by the aggregate Number of Warrants of such Certificated Warrant, and will credit or cause to be
credited the account of the Person specified in the instructions provided by the exchanging Warrantholder in an amount equal to
the aggregate Number of Warrants of such Certificated Warrant. If no Global Warrants are then outstanding, the Company, in accordance
with Section 2.02, will promptly execute and deliver to the Warrant Agent, and the Warrant Agent, upon receipt of an Authentication
Order, will, in accordance with Section 2.02, authenticate, a new Global Warrant in the appropriate aggregate Number of Warrants.

Warrant Agent shall use “CUSIP” numbers in notices as a convenience to Warrantholders; provided that any such
notice may state that no representation is made as to the correctness of such numbers either as printed on the Warrants or as contained
in any notice and that reliance may be placed only on the other identification numbers printed on the Warrants, and any such notice
shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Warrant Agent of any change
in the “CUSIP” numbers.

Notice set forth on the reverse of the Warrant Certificate duly completed and executed, together with any applicable transfer taxes
as set forth in Section 6.01(b), or (ii) in the case of a Global Warrant, the Warrantholder must comply with the procedures established
by the Depositary for the exercise of Warrants.

 

(b)          The
date on which a Warrantholder complies with the requirements for exercise set forth in this Section 3.02 in respect of a Warrant
is the “Exercise Date” for such Warrant. However, if such date is not a Trading Day or the Warrantholder satisfies
such requirements after the Close of Business on a Trading Day, then the Exercise Date shall be the immediately succeeding Trading
Day, unless that Trading Day falls after the Expiration Date, in which case the Exercise Date shall be the immediately preceding
Trading Day.

 

Section 3.03.         Settlement
of Warrants. (a) Full Physical Settlement shall apply to each Warrant unless the Warrantholder elects for Net Share Settlement
to apply upon exercise of such Warrant. Such election shall be made (i) in the case of a Certificated Warrant, in the Exercise
Notice for such Warrant, or (ii) in the case of a Global Warrant, in accordance with the procedures established by the Depositary
for the exercise of Warrants.

 

(b)          If
Full Physical Settlement is applicable with respect to the exercise of a Warrant, then, for each Warrant exercised hereunder, (i)
the Warrantholder shall pay the Exercise Price (determined as of such Exercise Date) prior to 11:00 a.m., New York City time, on
the Settlement Date for such Warrant, by federal wire or other immediately available funds payable to the order of the Company
to the account maintained by the Warrant Agent (provided, however, that if the Warrantholder shall pay the Exercise
Price after 11:00., New York City time, on the scheduled Settlement Date, then the Settlement Date shall thereafter be deemed to
be, for purposes of clause (ii) of this Section 3.03(b), the first Trading Day following completion of such payment), and (ii)
on the Settlement Date, following receipt by the Warrant Agent of such Exercise Price, the Company shall cause to be delivered
to the Warrantholder one share of Common Stock (the “Full Physical Share Amount”), together with Cash in respect
of any fractional Warrant as provided in Section 3.05. All funds received by the Warrant Agent upon exercise of such Warrant shall
be deposited by the Warrant Agent for the account of the Company in accordance with the instructions set forth on Annex A to this
Warrant Agreement (which may be updated from time to time by mutual agreement between the Company and the Warrant Agent) or in
accordance with such other instructions as may be otherwise agreed in writing between the Company and the Warrant Agent (subject
to the Warrant Agent’s customary procedures).

 

    	 	19	 

     

    

 

(c)          If
Net Share Settlement is applicable with respect to the exercise of a Warrant, then, for each Warrant exercised hereunder, on the
Settlement Date for such Warrant, the Company shall cause to be delivered to the Warrantholder a number of shares of Common Stock
(which in no event will be less than zero) (the “Net Share Amount”) equal to (i) the Net Share Settlement Price
as of the relevant Exercise Date, minus the Exercise Price (determined as of such Exercise Date), divided by (ii) such Net Share
Settlement Price, together with Cash in respect of any fractional shares or fractional Warrants as provided in Section 3.05.

 

Section 3.04.         Delivery
of Common Stock. (a) In connection with the delivery of shares of Common Stock to an exercising Warrantholder pursuant to Section
3.03(b) or Section 3.03(c), as the case may be, the Warrant Agent shall:

 

(i)          (A)
inform the Company of the number of Warrants which the Warrantholder desires to exercise and (A) if such shares of Common Stock
are in book-entry form at the Depositary, the Company shall (or shall cause the Transfer Agent to) deliver Common Stock to which
the Warrantholder is entitled by electronic transfer (with the assistance of the Company and the Transfer Agent, if necessary)
to such Warrantholder’s account, or any other account as such Warrantholder may designate, at the Depositary or at an Agent
Member, or (B) if such shares of Common Stock are not in book-entry form at the Depositary, the Company shall (or cause the Transfer
Agent to) deliver to or upon the order of such Warrantholder a certificate or certificates, in each case with legends thereon as
appropriate (as determined by the Company) and for the number of full shares of Common Stock to which such Warrantholder is entitled,
registered in such name or names as may be directed by such Warrantholder;

 

(ii)         deliver
Cash from the Company to such Warrantholder in respect of any fractional shares as provided in Section 3.05; and

 

(iii)        if
the Number of Warrants represented by a Warrant Certificate shall not have been exercised in full, deliver a new Warrant Certificate,
including any applicable legends required by this Warrant Agreement, countersigned by the Warrant Agent, for the balance of the
number of Warrants represented by the surrendered Warrant Certificate.

 

(b)          Each
Person in whose name any shares of Common Stock are issued shall for all purposes be deemed to have become the holder of record
of such shares as of the Exercise Date or, in the case of a Warrant subject to Full Physical Settlement only, the date of payment
by the Warrantholder of the Exercise Price in accordance with Section 3.03(b), if later. However, if any such date is a date when
the stock transfer books of the Company are closed, such Person shall be deemed to have become the holder of such shares at the
Close of Business on the next succeeding date on which the stock transfer books are open.

 

    	 	20	 

     

    

 

(c)          Each
share certificate representing Common Stock issued upon conversion of the Warrants that are Restricted Warrants shall bear the
Restricted Stock Legend as set forth in Section 2.04.

 

(d)          Promptly
after the Warrant Agent shall have taken the action required above (or at such later time as may be mutually agreeable to the Company
and the Warrant Agent), the Warrant Agent shall account to the Company with respect to any Warrants exercised (including, without
limitation, with respect to any Exercise Price paid to the Warrant Agent). The Company shall reimburse the Warrant Agent for any
amounts paid by the Warrant Agent in respect of a fractional share or fractional Warrant upon such exercise in accordance with
Section 3.05 hereof.

 

(e)          The
Company shall, or shall cause the Transfer Agent to, deliver any shares of Common Stock required to be delivered by the Company
in accordance with Section 3.04(a)(i) or pursuant to a Net Share Settlement by no later than the third Trading Day following the
related Exercise Date. The Company acknowledges and agrees that the timely delivery of Common Stock in accordance with this Section
3.04(e) is a material term of this Warrant Agreement.

 

Section 3.05.         No
Fractional Shares to Be Issued. (a) Notwithstanding anything to the contrary in this Warrant Agreement, the Company shall not
be required to issue any fraction of a share of Common Stock upon exercise of any Warrants.

 

(b)          If
any fraction of a Warrant shall be exercised hereunder, the Company shall pay the relevant Warrantholder Cash in lieu of the corresponding
fraction of a share of Common Stock valued at the Net Share Settlement Price as of the Exercise Date. However, if more than one
Warrant shall be exercised hereunder at one time by the same Warrantholder, the number of full shares which shall be issuable upon
exercise thereof shall be computed on the basis of all Warrants (including any fractional Warrants) so exercised. If any fraction
of a share of Common Stock would, except for the provisions of this Section 3.05, be issuable on the exercise of any Warrant or
Warrants (including any fractional Warrants), the Company shall pay the Warrantholder Cash in lieu of such fractional shares valued
at the Net Share Settlement Price as of the Exercise Date.

 

(c)          Each
Warrantholder, by its acceptance of a Warrant Certificate, expressly waives its right to receive any fraction of a share of Common
Stock or a stock certificate representing a fraction of a share of Common Stock.

 

Section 3.06.         Acquisition
of Warrants by Company. The Company shall have the right, except as limited by law, to purchase or otherwise to acquire Warrants
at such times, in such manner and for such consideration as it may deem appropriate and shall have agreed with the holder of such
Warrants. The Company agrees that it will not, and will not permit its Subsidiaries to, resell any Warrants that they reacquire,
if any.

 

    	 	21	 

     

    

 

Section 3.07.         Direction
of Warrant Agent. (a) The Company shall be responsible for performing all calculations required in connection with the exercise
and settlement of the Warrants and the payment or delivery, as the case may be, of Cash and/or Common Stock as described in this
Article 3. In connection therewith, the Company shall provide prompt written notice to the Warrant Agent of the amount of Cash
and the number of shares of Common Stock payable or deliverable, as the case may be, upon exercise and settlement of the Warrants,
including, without limitation, the Net Share Amount and the Full Physical Share Amount.

 

(b)          Any
Cash to be paid, or Common Stock to be delivered, to the Warrantholders hereunder shall be delivered to the Warrant Agent no later
than the Business Day immediately preceding the date such consideration is required to be delivered to the Warrantholders.

 

(c)          The
Warrant Agent shall have no liability for any failure or delay in performing its duties hereunder caused by any failure or delay
of the Company in providing such calculations or items to the Warrant Agent. The Warrant Agent shall not be accountable with respect
to the validity or value (or the kind or amount) of any shares of Common Stock or other consideration that may at any time be issued
or delivered upon the exercise of any Warrant, and it makes no representation with respect thereto. The Warrant Agent shall not
be responsible for any failure of the Company to make any Cash payment or to issue, transfer or deliver any shares of Common Stock
or stock certificates or other consideration, or to comply with any of the covenants of the Company contained in this Article 3.

 

Section 3.08.         Exchange
Cap. (a) Notwithstanding anything to the contrary in this Warrant Agreement or in the Warrants, the Company shall not
be obligated to issue shares of Common Stock upon exercise of the Notes hereunder, and shall not be entitled to issue shares of
Common Stock in connection with any anti-dilution terms described hereunder, to the extent (and only to the extent) the issuance
of such shares of Common Stock, would exceed that aggregate number of shares of Common Stock which the Company may issue, in the
aggregate, pursuant to the terms of all Warrants and the Notes without breaching the Company’s obligations under the rules
or regulations of the Principal Market (the number of shares which may be issued without violating such rules and regulations,
including rules related to the aggregate of offerings under NASDAQ Listing Rule 5635(d), the “Exchange Cap”),
except that such limitation shall not apply in the event that the Company obtains and delivers written notice to the Warrant Agent
of (A) the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of shares of
Common Stock upon conversion or exercise (as the case may be) of the Notes and the Warrants or otherwise pursuant to the terms
of the Indenture and this Warrant Agreement in excess of such amount or (B) a written confirmation from the Principal Market that
such approval is not required. Until such approval or such written confirmation is obtained, no Warrantholder shall be issued in
the aggregate, upon conversion or exercise (as the case may be) of any Warrants or any of the Notes or otherwise pursuant to the
terms of the Note or this Warrant Agreement, shares of Common Stock in an amount greater than the product of (i) the Exchange Cap
multiplied by (ii) the quotient of (A) the aggregate number of shares of Common Stock underlying the Notes and Warrants initially
purchased by such Holder from the Initial Purchaser on, and determined as of, the Closing Date (for clarity, as if the Notes and
Warrants had been converted and exercised in full on the Closing Date, prior to any adjustments that may later occur with respect
to the applicable conversion or exercise price) divided by (B) the aggregate number of shares of Common Stock underlying the all
Notes and all Warrants initially purchased by all Holders from the Initial Purchaser on, and determined as of, the Closing Date
(for clarity, as if the Notes and Warrants had been converted and exercised in full on the Closing Date, prior to any adjustments
that may later occur with respect to the applicable conversion or exercise price) (with respect to each Warrantholder, the “Exchange
Cap Allocation”). In the event that any Warrantholder shall sell or otherwise transfer any of such Warrantholders Warrants,
the transferee shall be allocated a pro rata portion of such Warrantholder’s Exchange Cap Allocation based on the relative
number of underlying shares determined as of the Closing Date with respect to such portion of such Warrants and any Notes so transferred,
and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation
so allocated to such transferee. Upon conversion and exercise in full of a holder’s Notes and Warrants, the difference (if
any) between such holder’s Exchange Cap Allocation and the number of shares of Common Stock actually issued to such holder
upon such holder’s conversion in full of such holder’s Notes and exercise in full of such Warrants shall be allocated
to the respective Exchange Cap Allocations of the remaining holders of Notes and Warrants on a pro rata basis in proportion to
the shares of Common Stock then underlying the Notes and Warrants held by each such holders of Notes and Warrantholders at such
time.

 

    	 	22	 

     

    

 

(b)          In
the event that the Company is prohibited from issuing shares of Common Stock pursuant to Section 3.08(a) (the “Exchange
Cap Shares”), the Company shall pay cash in exchange for the cancellation of such shares of Common Stock at a price equal
to the sum of the product of (x) such number of Exchange Cap Shares and (y) the simple average of the Daily VWAP for Common Stock
for the ten consecutive VWAP Trading Days ending on and included the VWAP Trading Day immediately prior to the Exercise Date (the
“Exchange Cap Share Cancellation Amount”); provided, that no Exchange Cap Share Cancellation Amount shall be
due and payable to the Warrantholder to the extent that (x) on or prior to the applicable Warrant Share Delivery Date, the Exchange
Cap Allocation of a Warrantholder is increased (whether by assignment by a holder of Notes and/or Warrants or all, or any portion,
of such holder's Exchange Cap Allocation or otherwise) (an “Exchange Cap Allocation Increase”) and (y) after
giving effect to such Exchange Cap Allocation Increase, the Company delivers the applicable Exchange Cap Shares to the Warrantholder
(or its designee) on or prior to the applicable Warrant Share Delivery Date. For the avoidance of any doubt, the term Warrantholder
includes any beneficial interest holder in the case of any Notes represented by a Global Note and any Warrants represented by a
Global Warrant where such instruments are registered in the name of a Depositary or a nominee thereof. BY ITS ACQUISITION HEREOF
OR OF A BENEFICIAL INTEREST HEREIN, THE ACQUIRER AGREES IT WILL NOT CONVERT OR EXERCISE THE NOTES OR WARRANTS IN CONTRAVENTION
OF THIS PARAGRAPH.

 

Section 3.09.         Beneficial
Ownership Limitation on Exercises. (a) Notwithstanding anything to the contrary contained herein, the Company shall not effect
the exercise of any Warrant, and no Warrantholder shall have the right to exercise any Warrant, and any such exercise shall be
null and void and treated as if never made, and the Company shall not be entitled to issue shares of Common Stock in connection
with any anti-dilution terms described hereunder, to the extent that after giving effect to such exercise, the Warrantholder together
with the other Attribution Parties collectively would beneficially own in excess of 4.99% (the “Maximum Percentage”)
of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence,
the aggregate number of shares of Common Stock beneficially owned by such Warrantholder and the other Attribution Parties shall
include the number of shares of Common Stock held by the Warrantholder and all other Attribution Parties plus the number of shares
of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made,
but shall exclude shares of Common Stock which would be issuable upon (A) exercise of the remaining, unexercised portion of this
Warrant beneficially owned by the Warrantholder or any of the other Attribution Parties and (B) exercise or conversion of the unexercised
or unconverted portion of any Notes or any other securities of the Company (including, without limitation, any convertible notes
or convertible preferred stock or warrants, including other Warrants) beneficially owned by the Warrantholder or any other Attribution
Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section 3.09. For purposes
of this Section 3.09, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act.

 

    	 	23	 

     

    

 

(b)          For
purposes of determining the number of outstanding shares of Common Stock the Warrantholder may acquire upon the exercise of a Warrant
without exceeding the Maximum Percentage, such Warrantholder may rely on the number of outstanding shares of Common Stock as reflected
in (x) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or
other public filing with the SEC, as the case may be, or (y) any other written notice by the Company, if any, setting forth the
number of shares of Common Stock outstanding (the “Reported Outstanding Share Number”). If the Company receives
an Exercise Notice from a Warrantholder at a time when the actual number of outstanding shares of Common Stock is less than the
Reported Outstanding Share Number, the Company shall (i) notify the Warrantholder in writing of the number of shares of Common
Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Warrantholder’s beneficial
ownership, as determined pursuant to this Section 3.09, to exceed the Maximum Percentage, the Warrantholder must notify the Company
of a reduced number of shares of Common Stock to be acquired pursuant to such Exercise Notice (the number of shares by which such
purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company shall return
to the Warrantholder any exercise price paid by the Warrantholder for the Reduction Shares. For any reason at any time, upon the
written or oral request of a Warrantholder the Company shall within one (1) Business Day confirm orally and in writing or by electronic
mail to such Warrantholder 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 any
Warrants and Notes, by the Warrantholder and any other Attribution Party since the date as of which the Reported Outstanding Share
Number was reported. In the event that the issuance of shares of Common Stock to the Warrantholder upon exercise of a Warrant results
in the Warrantholder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the Maximum
Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the Exchange Act), the number
of shares so issued by which the Warrantholder’s and the other Attribution Parties’ aggregate beneficial ownership
exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab
initio, and the Warrantholder shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable
after the issuance of the Excess Shares has been deemed null and void, the Company shall return to the Warrantholder the Exercise
Price paid by the Warrantholder for the Excess Shares.

 

(c)          Upon
delivery of a written notice to the Company, a Warrantholder may from time to time increase (with such increase not effective until
the sixty-first (61st) day after delivery of such notice) or decrease the Maximum Percentage to any other percentage
not in excess of 9.99% as specified in such notice; provided that (i) any such increase in the Maximum Percentage will not be effective
until the sixty-first (61st) day after such notice is delivered to the Company and (ii) any such increase or decrease
will apply only to such Warrantholder and the other Attribution Parties and not to any other Warrantholder that is not an Attribution
Party of the Warrantholder delivering such notice.

 

    	 	24	 

     

    

 

(d)          For
purposes of clarity, the shares of Common Stock issuable pursuant to the terms of any Warrant in excess of the Maximum Percentage
shall not be deemed to be beneficially owned by the Warrantholder for any purpose including for purposes of Section 13(d) or Rule
16a-1(a)(1) of the Exchange Act. No prior inability to exercise this Warrant pursuant to this Section 3.09 shall have any effect
on the applicability of the provisions of Section 3.09 with respect to any subsequent determination of exercisability. The provisions
of Section 3.09 shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section
3.09 to the extent necessary to correct this Section 3.09 or any portion of Section 3.09 which may be defective or inconsistent
with the intended beneficial ownership limitation contained in this Section 3.09 or to make changes or supplements necessary or
desirable to properly give effect to such limitation.

 

(e)          For
the avoidance of any doubt, the term Warrantholder for the purposes of this Section 3.09 includes any beneficial interest holder
in the case of any Warrants represented by a Global Warrant where such instrument is registered in the name of a Depositary or
a nominee thereof.

 

(f)          The
limitation contained in Section 3.09 may not be waived and shall apply to any successor holders of each Warrant.

 

(g)          The
Warrant Agent shall have no obligation to monitor the Company and
each Warrantholder’s compliance with this Section 3.09.

 

ARTICLE 4

ADJUSTMENTS; FUNDAMENTAL TRANSACTION

 

Section 4.01.         Adjustments
to Exercise Price. The Exercise Price for the Warrants then remaining outstanding and unexercised shall be subject to adjustment
(without duplication) upon the occurrence of any of the following events; provided, in no case under this Section 4.01 will the
Exercise Price be reduced to a price that would result in shares of Common Stock being issued below the par value per share of
Common Stock thereof:

 

(a)          The
issuance of Common Stock as a dividend or distribution to all holders of Common Stock, or a subdivision or combination of Common
Stock, in which event the Exercise Price shall be adjusted based on the following formula:

 

	EP1 = EP0 x	OS0	 
	OS1	 

 

    	 	25	 

     

    

 

where:

 

		EP0 =	the Exercise Price in effect immediately prior to the Close
of Business on the Record Date for such dividend or distribution, or immediately prior to the Open of Business on the effective
date for such subdivision or combination, as the case may be;

 

		EP1 =	the Exercise Price in effect immediately after the Close
of Business on the Record Date for such dividend or distribution, or immediately after the Open of Business on the effective date
for such subdivision or combination, as the case may be;

 

		OS0=	the number of shares of Common Stock outstanding immediately
prior to the Close of Business on the Record Date for such dividend or distribution, or immediately prior to the Open of Business
on the effective date for such subdivision or combination, as the case may be; and

 

		OS1=	the number of shares of Common Stock that would be outstanding
immediately after, and solely as a result of, such dividend, distribution, subdivision or combination.

 

Such adjustment shall
become effective immediately after the Close of Business on the Record Date for such dividend or distribution, or immediately after
the Open of Business on the effective date for such subdivision or combination, as the case may be. If any dividend or distribution
or subdivision or combination of the type described in this Section 4.01(a) is declared or announced but not so paid or made, the
Exercise Price shall again be adjusted to the Exercise Price that would then be in effect if such dividend or distribution or subdivision
or combination had not been declared or announced, as the case may be.

 

(b)          The
dividend or distribution to all holders of Common Stock of (i) shares of the Company’s Capital Stock (other than Common Stock),
(ii) evidences of the Company’s indebtedness, (iii) rights or warrants to purchase the Company’s securities or the
Company’s assets or (iv) property or Cash (excluding any ordinary cash dividends declared by the Board of Directors and excluding
any dividend, distribution or issuance covered by clauses (a) or (b) above), in which event the Exercise Price will be adjusted
based on the following formula:

 

	EP1 = EP0 x	SP0 - FMV	 
	 	SP0	 

 

where:

 

		EP0 =	the Exercise Price in effect immediately prior to the Close
of Business on the Record Date for such dividend or distribution;

 

		EP1 =	the Exercise Price in effect immediately after the Close
of Business on the Record Date for such dividend or distribution;

 

		SP0 =	the Current Market Price; and

 

    	 	26	 

     

    

 

		FMV =	the fair market value (as determined in good faith by the
Board of Directors), on the Record Date for such dividend or distribution, of the shares of Capital Stock, evidences of indebtedness
or property, rights or warrants so distributed or the amount of Cash (other than in the case of ordinary cash dividends declared
by the Board of Directors) expressed as an amount per share of outstanding Common Stock.

 

Such decrease shall
become effective immediately after the Close of Business on the Record Date for such dividend or distribution. In the event that
such dividend or distribution is declared or announced but not so paid or made, the Exercise Price shall again be adjusted to be
the Exercise Price which would then be in effect if such distribution had not been declared or announced.

 

However, if the transaction
that gives rise to an adjustment pursuant to this clause (b) is one pursuant to which the payment of a dividend or other distribution
on Common Stock consists of shares of capital stock of, or similar equity interests in, a Subsidiary of the Company or other business
unit of the Company (i.e., a spin-off) that are, or, when issued, will be, traded or quoted on the Nasdaq Capital Market or any
other national securities exchange or market, then the Exercise Price will instead be adjusted based on the following formula:

 

	EP1 = EP0 x	MP0	 
	MP0 + FMV0	 

 

where:

 

		EP0 =	the Exercise Price in effect immediately prior to the Close
of Business on the Record Date for such dividend or distribution;

 

		EP1 =	the Exercise Price in effect immediately after the Close
of Business on the Record Date for such dividend or distribution;

 

		FMV0=	the average of the Closing Sale Prices of the Capital Stock
or similar equity interests distributed to holders of Common Stock applicable to one share of Common Stock over the 10 consecutive
Trading Days commencing on, and including, the third Trading Day after the Ex-Date for such dividend or distribution; and

 

		MP0=	the average of the Closing Sale Prices of the Common Stock
over the 10 consecutive Trading Days commencing on, and including, the third Trading Day after the Ex-Date for such dividend or
distribution.

  

Such decrease shall
become effective immediately after the Ex-Date for such dividend or distribution. In the event that such dividend or distribution
is declared or announced but not so paid or made, the Exercise Price shall again be adjusted to be the Exercise Price which would
then be in effect if such distribution had not been declared or announced.

 

    	 	27	 

     

    

 

(c)          If
the Company issues or sells shares of Common Stock (including shares of Common Stock deemed to be issued pursuant to the fourth
paragraph of this Section 4.01(c)) in a Qualified Financing at a price per share less than the applicable Exercise Price on the
Trading Day immediately preceding such issuance or sale, the Exercise Price will be adjusted based on the following formula:

 

	EP1 = EP0 x	(OS0  + Y)
	(OS0  + X)

 

where,

 

		EP0=	the Exercise Price in effect immediately prior to the Open
of Business on the date of such issuance or sale (or deemed issuance);

 

		EP1=	the Exercise Price in effect immediately after the Open
of Business on the date of such issuance or sale (or deemed issuance);

 

		OS =	the number of shares of Common Stock outstanding immediately
prior to the Open of Business on the date of such issuance or sale (or deemed issuance);

 

		X =	the total number of shares of Common Stock issued or sold
(or deemed issued) on such date; and

 

		Y =	the number of shares of Common Stock equal to the quotient
of (A) the aggregate purchase price of the shares of Common Stock issued or sold (or deemed issued) and (B) the Exercise Price
of the Warrants on the Trading Day immediately preceding such issuance or sale (or deemed issuance).

 

For the purpose of
the above calculation, the number of shares of Common Stock outstanding immediately prior to the Open of Business on the date of
such issuance or sale shall be calculated on a fully diluted basis, as if all then outstanding options, warrants and other convertible
securities had been fully exercised or converted (and the resulting securities fully converted into shares of Common Stock, if
so convertible) as of such date.

 

Any adjustment made
pursuant to this Section 4.01(c) shall become effective immediately following the Open of Business on the date of such issuance
or sale. If Section 4.01(a) or (b) applies to any distribution of shares of Common Stock or Notes, this Section 4.01(c) shall not
apply to such distribution. In no event shall the Exercise Price be increased pursuant to this Section 4.01(c).

 

In the event the Company
at any time or from time to time after the Closing Date shall issue any options or convertible securities or shall fix a record
date for the determination of holders of any class of securities then entitled to receive any such options or convertible securities,
then the maximum number of shares (as set forth in the instrument relating thereto without regard to any provisions contained therein
designed to protect against dilution) of Common Stock issuable upon the exercise of such options or, in the case of convertible
securities and options therefor, the conversion or exchange of such convertible securities, shall be deemed to be shares of Common
Stock issued as of the time of such issuance or, in case such a record date shall have been fixed, as of the Close of Business
on such record date provided, however, that in any such case in which shares of Common Stock are deemed to be issued
no further adjustments to the Exercise Price shall be made upon the subsequent issue of shares of Common Stock upon the exercise
of such options or conversion or exchange of such convertible securities. The consideration per share received by the Company for
shares of Common Stock deemed to have been issued pursuant to this paragraph relating to options and convertible securities shall
be determined by dividing:

 

    	 	28	 

     

    

  

		(1)	the total amount, if any, received or receivable by the Company as consideration for the issuance
of such options or convertible securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments
relating thereto, without regard to any provision contained therein designed to protect against dilution) payable to the Company
upon the exercise of such options or the conversion or exchange of such convertible securities, or in the case of options for convertible
securities, the exercise of such options for convertible securities and the conversion or exchange of such convertible securities,
by

 

		(2)	the maximum number of shares of Common Stock (as set forth in the instruments relating thereto,
without regard to any provision contained therein designed to protect against the dilution) issuable upon the exercise of such
options or conversion or exchange of such convertible securities, or in the case of options for convertible securities, the exercise
of such options for convertible securities and the conversion or exchange of such convertible securities.

 

Notwithstanding the
foregoing, if the terms of any option or convertible security, the issuance of which resulted in an adjustment to the Exercise
Price of the Warrants pursuant to this subsection 4.01(c), are revised as a result of an amendment to such terms or any other adjustment
pursuant to the provisions of such option or convertible security (but excluding automatic adjustments to such terms pursuant to
anti-dilution or similar provisions of such option or convertible security) to provide for either (i) any increase or decrease
in the number of shares of Common Stock issuable upon the exercise, conversion and/or exchange of any such option or convertible
security or (ii) any increase or decrease in the consideration payable to the Company upon such exercise, conversion and/or exchange,
then effective upon such increase or decrease becoming effective, the Exercise Price of the Warrants computed upon the original
issue of such option or convertible security (or upon the occurrence of a record date with respect thereto) shall be readjusted
to such Exercise Price as would have obtained had such revised terms been in effect upon the original date of issuance of such
option or convertible security; provided, however, that any adjustments to the Exercise Price pursuant to this paragraph
shall not be effective with respect to any Warrants that have been exercised prior to the date of any of the actions described
in this paragraph.

 

(d)          For
the purposes of Section 4.01(a), (b) and (c), any dividend or distribution to which Section 4.01(b) is applicable that also includes
shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock (or both), shall be deemed instead
to be a dividend or distribution of the indebtedness, assets or shares of Capital Stock other than such shares of Common Stock
or rights or warrants (and any Exercise Price adjustment required by Section 4.01(b) with respect to such dividend or distribution
shall be made in respect of such dividend or distribution (without regard to the parenthetical in Section 4.01(b) that begins with
the word “excluding”)) immediately followed by a dividend or distribution of such shares of Common Stock or such rights
or warrants (and any further Exercise Price adjustment required by Section 4.01 with respect to such dividend or distribution shall
then be made), except, for purposes of such adjustment, any shares of Common Stock included in such dividend or distribution shall
not be deemed “outstanding immediately prior to the Close of Business on the Record Date.”

 

    	 	29	 

     

    

 

(e)          Prior
to September 28, 2017, the Company shall not in any manner issue or sell or enter into any agreement to issue or sell, any Common
Stock, options, warrants or convertible securities, after the Closing Date, that are issuable pursuant to such agreement or convertible
into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary with the market price of the
shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting
customary anti-dilution provisions (such as share splits, share combinations, share dividends and similar transactions) and also
exclusive of such formulations reflecting customary price-based anti-dilution provisions. For avoidance of doubt, the Company’s
obligations to adjust the Exercise Price pursuant to the terms of this Section 4.01 shall not be prohibited by this Section 4.01(e).

 

Section 4.02.         Adjustments
to Number of Warrants. Concurrently with any adjustment to the Exercise Price under Section 4.01, the Number of Warrants for
each Warrant Certificate will be adjusted such that the Number of Warrants for each such Warrant Certificate in effect immediately
following the effectiveness of such adjustment will be equal to the Number of Warrants for each such Warrant Certificate in effect
immediately prior to such adjustment, multiplied by a fraction, (i) the numerator of which is the Exercise Price in effect
immediately prior to such adjustment and (ii) the denominator of which is the Exercise Price in effect immediately following such
adjustment.

 

Section 4.03.         Certain
Distributions of Rights and Warrants; Stockholder Rights Plan. (a) Rights or warrants distributed by the Company to all holders
of Common Stock (including under any Stockholder Rights Plan in existence on the date hereof or hereafter put into effect) entitling
the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain
circumstances), which rights or warrants, until the occurrence of a specified event or events (a “Trigger Event”):

 

		(i)	are deemed to be transferred with such shares of Common Stock;

 

		(ii)	are not exercisable; and

 

		(iii)	are also issued in respect of future issuances of Common Stock,

 

shall be deemed not to have been distributed
for purposes of Article 4 (and no adjustment to the Exercise Price or the Number of Warrants under this Article 4 will be made)
until the occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed
and an appropriate adjustment (if any is required) to the Exercise Price and the Number of Warrants for each Warrant Certificate
shall be made under this Article 4 (subject in all respects to Section 4.03(d)).

    	 	30	 

     

    

 

(c)          If
any such right or warrant is subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase
different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall
be deemed to be the date of distribution and Record Date with respect to new rights or warrants with such rights (subject in all
respects to Section 4.03(d)).

 

(d)          In
addition, except as set forth in Section 4.03(d), in the event of any distribution (or deemed distribution) of rights or warrants,
or any Trigger Event or other event (of the type described in Section 4.03) with respect thereto that was counted for purposes
of calculating a distribution amount for which an adjustment to the Exercise Price and the Number of Warrants for each Warrant
Certificate under Article 4 was made (including any adjustment contemplated in Section 4.03(d)):

 

(i)          in
the case of any such rights or warrants that shall all have been redeemed or repurchased without exercise by the holders thereof,
the Exercise Price and the Number of Warrants for each Warrant Certificate shall be readjusted upon such final redemption or repurchase
to give effect to such distribution or Trigger Event, as the case may be, as though it were a Cash distribution, equal to the per
share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming
such holder had retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase;
and

 

(ii)         in
the case of such rights or warrants that shall have expired or been terminated without exercise by the holders thereof, the Exercise
Price and the Number of Warrants for each Warrant Certificate shall be readjusted as if such rights and warrants had not been issued.

 

(e)          If
a Company stockholders rights plan under which any rights are issued provides that each share of Common Stock issued upon exercise
of Warrants at any time prior to the distribution of separate certificates representing such rights shall be entitled to receive
such rights, prior to the separation of such rights from the Common Stock, the Exercise Price and the Number of Warrants for each
Warrant Certificate shall not be adjusted pursuant to Section 4.01. If, however, prior to any exercise of a Warrant, such rights
have separated from the Common Stock, the Exercise Price and the Number of Warrants for each Warrant Certificate shall be adjusted
at the time of separation as if the Company dividended or distributed to all holders of Common Stock, the Company’s Capital
Stock, evidences of the Company’s indebtedness, certain rights or warrants to purchase the Company’s securities or
other of the Company’s assets as described in Section 4.01(b), subject to readjustment in the event of the expiration, termination
or redemption of such rights.

 

Section 4.04.         No
Impairment. The Company will not, by amendment of 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 to be observed or performed hereunder by the Company, but will at all times in
good faith assist in the carrying out of all the provisions of this Warrant and in taking of all such action as may be necessary
or appropriate in order to protect the rights of the Warrantholder.

 

    	 	31	 

     

    

 

 

Section 4.05.         Discretionary
Adjustments. The Company may from time to time, to the extent permitted by law and subject to applicable rules of the Nasdaq
Capital Market, decrease the Exercise Price and/or increase the Number of Warrants for each Warrant Certificate by any amount for
any period of at least 20 days. In that case, the Company shall give the Warrantholders at least 15 days’ prior notice of
such increase or decrease, and such notice shall state the decreased Exercise Price and/or increased Number of Warrants for each
Warrant Certificate and the period during which the decrease and/or increase will be in effect. The Company may make such decreases
in the Exercise Price and/or increases in the Number of Warrants for each Warrant Certificate, in addition to those set forth in
this Article 4, as the Company’s Board of Directors deems advisable, including to avoid or diminish any income tax to holders
of the Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated
as such for income tax purposes.

 

Section 4.06.         Restrictions
on Adjustments. (a) Except in accordance with Section 4.01, the Exercise Price and the Number of Warrants for any Warrant Certificate
will not be adjusted for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or carrying
the right to purchase any of the foregoing.

 

(b)          Neither
the Exercise Price nor the Number of Warrants for any Warrant Certificate will be adjusted:

 

(i)          upon
the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock
under any plan;

 

(ii)         for
a change in the par value of the Common Stock.

 

(c)          In
no event will the Company adjust the Exercise Price or make a corresponding adjustment to the Number of Warrants for any Warrant
Certificate to the extent that the adjustment would reduce the Exercise Price below the par value per share of Common Stock.

 

(d)          No
adjustment shall be made to the Exercise Price or the Number of Warrants for any Warrant Certificate for any of the transactions
described in Section 4.01 if the Company makes provisions for Warrantholders to participate in any such transaction without exercising
their Warrants on the same basis as holders of Common Stock and with notice that the Board of Directors determines in good faith
to be fair and appropriate.

 

(e)          No
adjustment shall be made to the Exercise Price, nor will any corresponding adjustment be made to the Number of Warrants for any
Warrant Certificate, unless the adjustment would result in a change of at least 1% of the Exercise Price; provided that,
any adjustments that are less than 1% of the Exercise Price shall be carried forward and such carried forward adjustments, regardless
of whether the aggregate adjustment is less than 1% of the Exercise Price, shall be made (i) annually, on each anniversary of the
Closing Date, (ii) immediately prior to the time of any exercise, and (iii) five Business Days prior to the Expiration Date, unless,
in each case, such adjustment has already been made.

 

    	 	32	 

     

    

 

(f)          If
the Company takes a record of the holders of Common Stock for the purpose of entitling them to receive a dividend or other distribution,
and thereafter (and before the dividend or distribution has been paid or delivered to stockholders) legally abandons its plan to
pay or deliver such dividend or distribution, then thereafter no adjustment to the Exercise Price or the Number of Warrants for
any Warrant Certificate then in effect shall be required by reason of the taking of such record.

 

Section 4.07.         Deferral
of Adjustments. In any case in which Section 4.01 provides that an adjustment shall become effective immediately after (a)
a Record Date for an event or (b) the effective date (in the case of a subdivision or combination of the Common Stock) (each a
“Determination Date”), the Company may elect to defer, until the later of the date the adjustment to the Exercise
Price and Number of Warrants for each Warrant Certificate can be definitively determined and the occurrence of the applicable Adjustment
Event (as hereinafter defined), (i) issuing to the Warrantholder of any Warrant exercised after such Determination Date and before
the occurrence of such Adjustment Event, the additional shares of Common Stock or other securities or assets issuable upon such
exercise by reason of the adjustment required by such Adjustment Event over and above the Common Stock issuable upon such exercise
before giving effect to such adjustment and (ii) paying to such Warrantholder any amount in Cash in lieu of any fractional share
of Common Stock or fractional Warrant pursuant to Section 3.05. For the purposes of this Section 4.07, the term “Adjustment
Event” shall mean in any case referred to in clause (a) or clause (b) hereof, the occurrence of such event.

 

Section 4.08.         Consolidation,
Merger and Sale of Assets.

 

(b)          Subject
to Section 4.09, the Company may, without the consent of the Warrantholders, consolidate with, merge into or sell, lease or otherwise
transfer in one transaction or a series of related transactions the consolidated assets of the Company and its Subsidiaries substantially
as an entirety to any corporation, limited liability company, partnership or trust organized under the laws of the United States
or any of its political subdivisions so long as:

 

(i)          the
Company complies with, or the Company causing the successor to assume all of the Company’s obligations under this Warrant
Agreement and the Warrants; and

 

(ii)         the
Company provides written notice of such assumption to the Warrant Agent.

 

(c)          In
case of any such consolidation, merger, sale, lease or other transfer that does not constitute a Fundamental Transaction and upon
any such assumption by the successor corporation, limited liability company, partnership or trust, such successor entity (the “Successor
Entity”) shall succeed to and be substituted for the Company with the same effect as if it had been named herein as the
Company. Such Successor Entity thereupon may cause to be signed, and may issue any or all of the Warrants issuable pursuant to
this Warrant Agreement which theretofore shall not have been signed by the Company; and, upon the order of such Successor Entity,
instead of the Company, and subject to all the terms, conditions and limitations in this Warrant Agreement prescribed, the Warrant
Agent shall authenticate and deliver, as applicable, any Warrants that previously shall have been signed and delivered by the Officers
of the Company to the Warrant Agent for authentication, and any Warrants which such Successor Entity thereafter shall cause to
be signed and delivered to the Warrant Agent for such purpose.

 

    	 	33	 

     

    

  

Section 4.09.         Fundamental
Transaction. (a) If, at any time while any Warrants remain outstanding and unexercised any of the following occur: (i) a “person”
or “group” within the meaning of Section 13(d) of the Exchange Act other than the Company, the Company’s Subsidiaries
or the Company’s or the Company’s Subsidiaries’ employee benefit plans files a Schedule TO or any schedule, form
or report under the Exchange Act disclosing that such person or group has become the direct or indirect “beneficial owner,”
as defined in Rule 13d-3 under the Exchange Act, of the Company’s common equity representing more than 50% of the voting
power of all outstanding classes of the Company’s common equity entitled to vote generally in the election of the Company’s
directors; (ii) the consummation of (A) any share exchange, consolidation or merger involving the Company pursuant to which the
Common Stock will be converted into cash, securities or other property or (B) any sale, lease or other transfer in one transaction
or a series of transactions of all or substantially all of the consolidated assets of the Company and the Company’s Subsidiaries,
taken as a whole, to any person other than one or more of the Company’s Subsidiaries; provided, however, that
a share exchange, consolidation or merger transaction described in clause (A) above in which the holders of more than 50% of all
shares of Common Stock entitled to vote generally in the election of the Company’s directors immediately prior to such transaction
own, directly or indirectly, more than 50% of all shares of Common Stock entitled to vote generally in the election of the directors
of the continuing or surviving entity or the parent entity thereof immediately after such transaction in substantially the same
proportions (relative to each other) as such ownership immediately prior to such transaction will not, in either case, be a Fundamental
Transaction (provided, however, that if a transaction occurs that constitutes a Fundamental Transaction under both clause
(i) and clause (ii) above, such transaction will be treated solely as a Fundamental Transaction under clause (ii) above) or (iii)
the Company’s stockholders approve any plan or proposal for the liquidation or dissolution of the Company (each under clause
(i) through (iii), a “Fundamental Transaction”), then, and in such event only if such Fundamental Transaction
is consummated and in full satisfaction of any and all amounts otherwise payable upon exercise of such unexercised Warrant, the
Company or the Successor Entity (as the case may be) shall be obligated to redeem, and the Warrantholder shall have the right to
receive, an amount equal to the Black Scholes Value of such unexercised Warrant less the Exercise Price. Payment of such amounts
shall be made by the Company or such Successor Entity (or at their direction) to the Warrantholder on or prior to the third Business
Day after the later to occur of (x) the date of the consummation of such Fundamental Transaction or (y) the date that the Black
Scholes Value has been determined in accordance with the terms of this Warrant Agreement (but in no event later than ten Business
Days after the date of the consummation of such Fundamental Transaction.

 

(b)          Nothing
in Section 3.09(a) shall limit the right of a Warrantholder to exercise (together with the payment of the Exercise Price or by
means of a Net Share Settlement) any Warrant in connection with, and contingent upon, such Fundamental Transaction and to receive
the consideration payable to holders of the Common Stock in lieu of not exercising such Warrant and receiving the Black Scholes
Value for such Warrant. In furtherance of the foregoing, the Company shall ensure that 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 Warrantholder, if such Warrantholder does timely exercise a Warrant on or prior to the closing of such Fundamental Transaction
shall be given the same choice as to the consideration available to holders of Common Stock, subject to the same terms and conditions,
if any, otherwise applicable to holders of Common Stock.

 

    	 	34	 

     

    

  

(c)          The
Company shall provide each Warrantholder and the Warrant Agent with written notice of any Fundamental Transaction no later than
20 days prior to the anticipated closing date of such Fundamental Transaction.

 

(d)          The
Company shall cause any Successor Entity in a Fundamental Transaction in which the Company is not the survivor to assume in writing
all of the obligations of the Company under this Section 4.09.

 

Section 4.10.         Common
Stock Outstanding. For the purposes of this Article 4, the number of shares of Common Stock at any time outstanding shall not
include shares held, directly or indirectly, by the Company, but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock.

 

Section 4.11.         Covenant
to Reserve Shares for Issuance on Exercise. (a) So long as any Warrants remain outstanding, the Company shall at all times
keep reserved for issuance under such Warrant a number of shares of Common Stock at least equal to 100% of the maximum number of
shares of Common Stock as shall be necessary to satisfy the Company’s obligation to issue shares of Common Stock under such
Warrants then outstanding (without regard to any limitations on exercise) (the “Required Reserve Amount”); provided
that at no time shall the number of shares of Common Stock reserved pursuant to this Section 4.11 be reduced other than proportionally
in connection with any exercise or redemption of any Warrants or such other event covered by Section 4.01. The Required Reserve
Amount (including, without limitation, each increase in the number of shares so reserved) shall be allocated pro rata among the
Warrantholders of the Warrants based on number of shares of Common Stock issuable upon exercise of Warrants held by each Warrantholder
on the Closing Date (without regard to any limitations on exercise) or increase in the number of reserved shares, as the case may
be (the “Authorized Share Allocation”). In the event that a Warrantholder shall sell or otherwise transfer any
of such Warrantholder’s Warrants, each transferee shall be allocated a pro rata portion of such Warrantholder’s Authorized
Share Allocation.

 

(b)          If,
notwithstanding Section 4.11(a), and not in limitation thereof, at any time while any Warrants remain outstanding, the Company
does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve the
Required Reserve Amount (an “Authorized Share Failure”), then (i) the Company shall immediately take all action
necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve
the Required Reserve Amount for all the Warrants then outstanding and (ii), without limiting clause (i), upon any exercise of a
Warrant to the extent as would be limited as to the issuance of Common Stock due to the Authorized Share Failure, the Company shall,
in addition to a settlement of the Warrant in Common Stock to the extent not limited by an Authorized Share Failure, pay, within
three (3) Business Days of the Exercise Date, an amount of Cash in exchange for the cancellation of such Warrants for shares of
Common Stock that cannot be issued to the Warrantholder due to the Authorized Share Failure at a price equal to the sum of the
product of (x) such number of Common Stock that cannot be issued due to the Authorized Share Failure and (y) the simple average
of the Daily VWAP for Common Stock for the ten consecutive VWAP Trading Days ending on and included the VWAP Trading Day immediately
prior to the Exercise Date net of the related Exercise Price for such related shares of Common Stock that would have otherwise
been issued (as may be adjusted to give effect for any related Net Share Settlement in lieu of a full exercise of such Warrant).
Without limiting the generality of the foregoing clause (i), as soon as practicable after the date of the occurrence of an Authorized
Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall
hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection
with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit
its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend
to the stockholder that they approve such proposal.

 

    	 	35	 

     

    

  

(c)          The
Company agrees to authorize and direct its Transfer Agent to reserve for issuance the number of shares of Common Stock specified
in this Section 4.11. The Company shall instruct the Transfer Agent to deliver to the Warrant Agent, upon written request from
the Warrant Agent substantially in the form of Exhibit F (or as separately agreed between the Warrant Agent and the Transfer Agent),
stock certificates (or beneficial interests therein) required to honor outstanding Warrants upon exercise thereof in accordance
with the terms of this Warrant Agreement. The Company shall pay to the Warrant Agent, as agent for the Warrantholders, any Cash
that may be payable as provided in this Article 4. Promptly after the date of expiration of Warrants and upon written request of
the Company, the Warrant Agent shall certify to the Company the aggregate Number of Warrants then outstanding, and thereafter no
shares shall be required to be reserved in respect of such Warrants.

 

Section 4.12.         Calculations
Final. The Company shall be responsible for making all calculations called for under this Warrant Agreement. These calculations
include, but are not limited to, the Exercise Date, the Current Market Price, the Closing Sale Price, the Net Share Settlement
Price, the Exercise Price, the Number of Warrants for each Warrant Certificate and the number of shares of Common Stock or other
consideration, if any, to be issued upon exercise of any Warrants. The Company shall make the foregoing calculations in good faith
and, absent manifest error, the Company’s calculations shall be final and binding on Warrantholders. The Company shall provide
a schedule of the Company’s calculations to the Warrant Agent, and the Warrant Agent is entitled to rely upon the accuracy
of the Company’s calculations without independent verification.

 

Section 4.13.         Notice
of Adjustments. Whenever the Exercise Price or the Number of Warrants for each Warrant Certificate is adjusted, the Company
shall promptly mail to Warrantholders in accordance with Section 6.15 a notice of the adjustment. The Company shall file with the
Warrant Agent such notice and an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner
of computing it. The certificate shall be conclusive evidence that the adjustment is correct, and the Warrant Agent shall not be
deemed to have any knowledge of any adjustments unless and until it has received such certificate. The Warrant Agent shall not
be under any duty or responsibility with respect to any such certificate except to exhibit the same to any Warrantholder desiring
inspection thereof.

 

    	 	36	 

     

    

 

Section 4.14.         Warrant
Agent Not Responsible for Adjustments or Validity. The Warrant Agent shall at no time be under any duty or responsibility to
any Warrantholder to determine whether any facts exist that may require an adjustment of the Exercise Price and the Number of Warrants
for each Warrant Certificate, or with respect to the nature or extent of any such adjustment when made, or with respect to the
method employed, herein or in any supplemental agreement provided to be employed, in making the same. The Warrant Agent shall have
no duty to verify or confirm any calculation called for hereunder. The Warrant Agent shall have no liability for any failure or
delay in performing its duties hereunder caused by any failure or delay of the Company in providing such calculations to the Warrant
Agent. The Warrant Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of
Common Stock or of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant or
upon any adjustment pursuant to this Article 4, and it makes no representation with respect thereto. The Warrant Agent shall not
be responsible for any failure of the Company to make any Cash payment or to issue, transfer or deliver any shares of Common Stock
or stock certificates or other securities or property or scrip upon the surrender of any Warrant for the purpose of exercise or
upon any adjustment pursuant to this Article 4, or to comply with any of the covenants of the Company contained in this Article
4.

 

Section 4.15.         Statements
on Warrants. The form of Warrant Certificate need not be changed because of any adjustment made pursuant to this Article 4,
and Warrant Certificates issued after such adjustment may state the same information (other than the adjusted Exercise Price and
the adjusted Number of Warrants for such Warrant Certificates) as are stated in the Warrant Certificates initially issued pursuant
to this Warrant Agreement. However, the Company may at any time in its sole discretion (which shall be conclusive) make any change
in the form of Warrant Certificate that it may deem appropriate and that does not materially adversely affect the interest of the
Warrantholders; and any Warrant Certificates thereafter issued or countersigned, whether in exchange or substitution for an outstanding
Warrant Certificate or otherwise, may be in the form as so changed.

 

ARTICLE 5

OTHER PROVISIONS RELATING TO RIGHTS OF WARRANTHOLDERS

 

Section 5.01.         No
Rights as Stockholders. Warrantholders shall not be entitled, by virtue of holding Warrants, to vote, to consent, to receive
dividends, to receive notice as stockholders with respect to any meeting of stockholders for the election of the Company’s
directors or any other matter, or to exercise any rights whatsoever as the Company’s stockholders unless, until and only
to the extent such holders become holders of record of shares of Common Stock issued upon settlement of the Warrants.

 

    	 	37	 

     

    

 

Section 5.02.         Mutilated
or Missing Warrant Certificates. If any Warrant at any time is mutilated, defaced, lost, destroyed or stolen, then on the terms
set forth in this Warrant Agreement, such Warrant may be replaced at the cost of the applicant (including legal fees of the Company
and the Warrant Agent) at the office of the Warrant Agent. The applicant for a new Warrant shall, in the case of any mutilated
or defaced Warrant, surrender such Warrant to the Warrant Agent and, in the case of any lost, destroyed or stolen Warrant, furnish
evidence satisfactory to the Company of such loss, destruction or theft, and, in each case, furnish evidence satisfactory to the
Company of the ownership and authenticity of the Warrant together with such indemnity as the Company and the Warrant Agent may
require. Any such new Warrant Certificate shall constitute an original contractual obligation of the Company, whether or not the
allegedly lost, stolen, mutilated or destroyed Warrant Certificate shall be at any time enforceable by anyone. An applicant for
such a substitute Warrant Certificate shall also comply with such other reasonable regulations and pay such other reasonable charges
as the Company or the Warrant Agent may prescribe. All Warrant Certificates shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the substitution for lost, stolen, mutilated or destroyed Warrant Certificates,
and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the
contrary with respect to the substitution for and replacement of negotiable instruments or other securities without their surrender.

 

Section 5.03.         Modification,
Waiver and Meetings. (a) This Warrant Agreement may be modified or amended by the Company and the Warrant Agent, without the
consent of the holder of any Warrant, for the purposes of curing any ambiguity or correcting or supplementing any defective provision
contained in this Warrant Agreement; provided that such modification or amendment does not adversely affect the interests of the
Warrantholders in any respect.

 

(b)          Modifications
and amendments to this Warrant Agreement or to the terms and conditions of Warrants may also be made by the Company and the Warrant
Agent, and noncompliance with any provision of the Warrant Agreement or Warrants may be waived, with the written consent of the
Warrantholders of Warrants representing at least two-thirds of the aggregate Number of Warrants at the time outstanding.

 

(c)          However,
no such modification, amendment or waiver may, without the written consent or the affirmative vote of each Warrantholder affected:

 

(i)          change
the Expiration Date;

 

(ii)         increase
the Exercise Price or decrease the Number of Warrants (except as explicitly set forth in Article 4);

 

(iii)        impair
the right to institute suit for the enforcement of any payment or delivery with respect to the exercise and settlement of any Warrant;

 

(iv)        impair
or adversely affect the exercise rights of Warrantholders, including any change to the calculation or payment of the Full Physical

ARTICLE 6

CONCERNING THE WARRANT AGENT AND OTHER MATTERS

 

Section 6.01.         Payment
of Certain Taxes. (a) The Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable
upon the initial issuance of the Warrants hereunder.

 

(b)          The
Company shall pay any and all documentary, stamp or similar issue or transfer taxes that may be payable upon the issuance of Common
Stock upon the exercise of Warrants hereunder and the issuance of stock certificates in respect thereof in the respective names
of, or in such names as may be directed by, the exercising Warrantholders; provided, however, that the Company shall not
be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such stock
certificate, any Warrant Certificates or other securities in a name other than that of the registered holder of the Warrant Certificate
surrendered upon exercise of the Warrant, and the Company shall not be required to issue or deliver such certificates or other
securities unless and until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of
such tax or shall have established to the satisfaction of the Company that such tax has been paid.

 

Section 6.02.         Change
of Warrant Agent. (a) The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged
from all further duties and liabilities hereunder after giving 60 days’ notice in writing to the Company, except that such
shorter notice may be given as the Company shall, in writing, accept as sufficient. If the office of the Warrant Agent becomes
vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor warrant agent in place
of the Warrant Agent. If the Company shall fail to make such appointment within a period of 60 days after it has been notified
in writing of such resignation or incapacity by the resigning or incapacitated warrant agent or by any holder of Warrants (who
shall, with such notice, submit his Warrant Certificate for inspection by the Company), then the holder of any Warrants may apply
to any court of competent jurisdiction for the appointment of a successor warrant agent.

 

    	 	39	 

     

    

  

(b)          The
Warrant Agent may be removed by the Company at any time upon 30 days’ written notice to the Warrant Agent; provided,
however, that the Company shall not remove the Warrant Agent until a successor warrant agent meeting the qualifications
hereof shall have been appointed.

 

(c)          Any
successor warrant agent, whether appointed by the Company or by such a court, shall be a corporation or banking association organized,
in good standing and doing business under the laws of the United States of America or any state thereof or the District of Columbia,
and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by Federal or state
authority and having a combined capital and surplus of not less than $50,000,000. The combined capital and surplus of any such
successor warrant agent shall be deemed to be the combined capital and surplus as set forth in the most recent report of its condition
published prior to its appointment; provided that such reports are published at least annually pursuant to law or to the
requirements of a Federal or state supervising or examining authority. After appointment, any successor warrant agent shall be
vested with all the authority, powers, rights, immunities, duties and obligations of its predecessor warrant agent with like effect
as if originally named as warrant agent hereunder, without any further act or deed; but if for any reason it becomes necessary
or appropriate, the predecessor warrant agent shall execute and deliver, at the expense of the Company, an instrument transferring
to such successor warrant agent all the authority, powers and rights of such predecessor warrant agent hereunder; and upon request
of any successor warrant agent, the Company shall make, execute, acknowledge and deliver any and all instruments in writing to
more fully and effectually vest in and conform to such successor warrant agent all such authority, powers, rights, immunities,
duties and obligations. Upon assumption by a successor warrant agent of the duties and responsibilities hereunder, the predecessor
warrant agent shall deliver and transfer, at the expense of the Company, to the successor warrant agent any property at the time
held by it hereunder. As soon as practicable after such appointment, the Company shall give notice thereof to the predecessor warrant
agent, the Warrantholders and the Transfer Agent. Failure to give such notice, or any defect therein, shall not affect the validity
of the appointment of the successor warrant agent.

 

(d)          Any
entity into which the 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 shall be a party, shall be the successor Warrant Agent under this Warrant Agreement
without any further act. In case at the time such successor to the Warrant Agent shall succeed to the agency created by this Warrant
Agreement, any of the Warrant Certificates shall have been countersigned but not delivered, any such successor to the Warrant Agent
may adopt the countersignature of the original 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 to the 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 Warrant Certificates shall have the full force provided in the Warrant Certificates and in this Warrant Agreement.

 

(e)          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 countersignatures 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 Warrant Agreement.

 

    	 	40	 

     

    

  

Section 6.03.         Compensation;
Further Assurances. The Company agrees that it will (a) pay the Warrant Agent reasonable compensation for its services as Warrant
Agent hereunder and, except as otherwise expressly provided, will pay or reimburse the Warrant Agent upon demand for all reasonable
expenses, disbursements and advances incurred or made by the Warrant Agent in accordance with any of the provisions of this Warrant
Agreement (including the reasonable compensation, expenses and disbursements of its agents and counsel) except any such expense,
disbursement or advance as may arise from its or any of their negligence or bad faith, and (b) 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 Warrant Agent for the carrying out or performing of the provisions of this Warrant Agreement.
The agreements of the Company in this Section 6.03 shall survive any termination of this Warrant Agreement or the earlier resignation
or removal of the Warrant Agent.

 

Section 6.04.         Reliance
on Counsel. The Warrant Agent may consult with legal counsel (who may be legal counsel for the Company), and the written opinion
of such counsel or any advice of legal counsel subsequently confirmed by a written 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 written opinion or advice.

 

Section 6.05.         Proof
of Actions Taken. Whenever in the performance of its duties under this Warrant Agreement the Warrant Agent shall deem it necessary
or desirable that any matter be proved or established by the Company prior to taking or suffering or omitting any action hereunder,
such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of bad faith on the
part of the Warrant Agent, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the
Warrant Agent; and such Officers’ Certificate shall, in the absence of bad faith on the part of the Warrant Agent, be full
warrant to the Warrant Agent for any action taken, suffered or omitted in good faith by it under the provisions of this Warrant
Agreement in reliance upon such certificate; but in its discretion the Warrant Agent may in lieu thereof accept other evidence
of such fact or matter or may require such further or additional evidence as to it may seem reasonable.

 

Section 6.06.         Correctness
of Statements. The Warrant Agent shall not be liable for or by reason of any of the statements of fact or recitals contained
in this Warrant Agreement or in the Warrant Certificates (except its countersignature thereof) or be required to verify the same,
and all such statements and recitals are and shall be deemed to have been made by the Company only.

 

    	 	41	 

     

    

 

Section 6.07.         Validity
of Agreement. The Warrant Agent shall not be under any responsibility in respect of the validity of this Warrant Agreement
or the execution and delivery hereof or in respect of the validity or execution of any Warrant Certificates (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Warrant Agreement
or in any Warrant Certificate; 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 Warrant Agreement or any Warrants or as to whether any
shares of Common Stock will, when issued, be validly issued and fully paid and nonassessable.

 

Section 6.08.         Use
of Agents. 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 attorneys or agents and the Warrant Agent shall not be responsible for the misconduct or negligence
of any agent or attorney, provided due care had been exercised in the appointment and continued employment thereof.

 

Section 6.09.         Liability
of Warrant Agent. The Warrant Agent shall incur no liability or responsibility to the Company or to any holder of Warrants
for any action taken in reliance on any notice, resolution, waiver, consent, order, certificate, or other paper, document or instrument
believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. The Company agrees to indemnify
the Warrant Agent and save it harmless against any and all losses, expenses and liabilities, including judgments, costs and reasonable
counsel fees, for anything done or omitted in good faith by the Warrant Agent in the execution of this Warrant Agreement or otherwise
arising in connection with this Warrant Agreement, except as a result of the Warrant Agent’s gross negligence or willful
misconduct, as determined by a final, nonappealable order of a court of competent jurisdiction. The Warrant Agent is entering into
this Warrant Agreement solely as an agent to the Company, and nothing herein shall create a fiduciary duty of the Warrant Agent
to either the Company or the Warrantholders. The agreements of the Company in this Section 6.09 shall survive termination of this
Warrant Agreement or the earlier resignation or removal of the Warrant Agent.

 

Section 6.10.         Legal
Proceedings. The Warrant Agent shall be under no obligation to institute any action, suit or legal proceeding or to take any
other action likely to involve expense unless the Company or one or more Warrantholders shall furnish the Warrant Agent with security
and indemnity satisfactory to the Warrant Agent for any costs and expenses which may be incurred, but this provision shall not
affect the power of the Warrant Agent to take such action as the Warrant Agent may consider proper, whether with or without any
such security or indemnity.

 

Section 6.11.         Other
Transactions in Securities of the Company. The Warrant Agent in its individual or any other capacity may become the owner of
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
Warrant Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any
other legal entity.

 

    	 	42	 

     

    

 

Section 6.12.         Actions
as Agent. The Warrant Agent shall act hereunder solely as agent and not in a ministerial or fiduciary capacity, and its duties
shall be determined solely by the provisions hereof. The duties and obligations of the Warrant Agent shall be determined solely
by the express provisions of the Warrant Agreement, and the Warrant Agent shall not be liable except for the performance of such
duties and obligations as are specifically set forth in the Warrant Agreement. No implied covenants or obligations shall be read
into the Warrant Agreement against the Warrant Agent. No provision of the Warrant Agreement shall require the Warrant Agent to
expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in
the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to it. The Warrant Agent shall not be liable for anything
that it may do or refrain from doing in good faith in connection with this Warrant Agreement except for its own gross negligence
or willful misconduct, as determined by a final, non-appealable order of a court of competent jurisdiction. In no event shall the
Warrant Agent be liable for any consequential loss or damage of any kind whatsoever (including but not limited to lost profits),
even if the Warrant Agent has been advised of the likelihood of such loss or damage and regardless of the form of action.

 

Section 6.13.         Force
Majeure. In no event shall the Warrant Agent be responsible or liable for any failure or delay in the performance of its obligations
hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes,
work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of
God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being
understood that the Warrant Agent shall use reasonable efforts that are consistent with accepted practices in the banking industry
to resume performance as soon as practicable under the circumstances.

 

Section 6.14.         Appointment
and Acceptance of Agency. The Company hereby appoints the Warrant Agent to act as agent for the Company in accordance with
the instructions set forth in this Warrant Agreement, and the Warrant Agent hereby accepts the agency established by this Warrant
Agreement and agrees to perform the same upon the terms and conditions herein set forth.

 

Section 6.15.         Successors
and Assigns. All the covenants and provisions of this Warrant Agreement by or for the benefit of the Company or the Warrant
Agent shall bind and inure to the benefit of their respective successors and assigns hereunder.

 

Section 6.16.         Notices.

    	 	3	 

     

    

 

(e)          Subject
to applicable law, the Company shall mail a Prospectus and a Notice and Questionnaire announcing the anticipated effective date
of the Shelf Registration Statement to each holder of Registrable Securities at least 30 days prior to the date on which the Company
anticipates in good faith that the Shelf Registration Statement will become effective. Each Holder of Registrable Securities agrees
that if it wishes to be named as a selling securityholder (“Selling Securityholder”) in the Prospectus and use
the Prospectus for resales of the Registrable Securities, it must in connection with naming such Holder as a Selling Securityholder
in the Shelf Registration Statement deliver a completed Notice and Questionnaire and such other information as the Company may
reasonably request in writing, if any, in connection with naming such Holder as a Selling Securityholder in the Shelf Registration
Statement to the Company at least ten Business Days prior to the anticipated effective date of the Shelf Registration Statement.
From and after the effective date of the Shelf Registration Statement, the Company and the Guarantors shall use reasonable best
efforts, as promptly as is practicable after the date a Notice and Questionnaire is delivered, and in any event within 15 Business
Days after such date, (i) if required by applicable law, to file with the Commission a post-effective amendment to the Shelf Registration
Statement or to prepare and, if permitted or required by applicable law, to file a supplement to the related Prospectus or an amendment
or supplement to any document incorporated therein by reference or file any other required document (including a report filed under
the Exchange Act, if permitted by applicable law) so that the Holder delivering such Notice and Questionnaire is named as a Selling
Securityholder in the Shelf Registration Statement and the related Prospectus, and so that such Holder is permitted to deliver
such Prospectus to purchasers of the Registrable Securities in accordance with applicable law and, if the Company and the Guarantors
shall file a post-effective amendment to the Shelf Registration Statement, use commercially reasonable efforts to cause such post-effective
amendment to be declared effective under the Act as promptly as is practicable; and (ii) notify such Holder as promptly as practicable
after the effectiveness under the Act of any post-effective amendment filed pursuant to Section 2(e)(i) hereof; provided,
however, that if such Notice and Questionnaire is delivered during a Deferral Period, the Company shall so inform the Holder
delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i) and (ii) above upon
expiration of the Deferral Period in accordance with Section 3(g) hereof. The Company shall be under no obligation to name
any Holder that is not a Notice Holder as a Selling Securityholder in the Shelf Registration Statement or related Prospectus; provided,
however, that any Holder that becomes a Notice Holder pursuant to the provisions of this Section 2(e) (whether or not
such Holder was a Notice Holder at the effective date of the Shelf Registration Statement) shall be named as a Selling Securityholder
in the Shelf Registration Statement or related Prospectus in accordance with the requirements of this Section 2(e). Notwithstanding
the foregoing, if the Notes are called for redemption, then the Company shall use reasonable best efforts to file the post-effective
amendment or supplement within five Business Days after the redemption date, or if such Notice and Questionnaire is delivered during
a Deferral Period, upon expiration of the Deferral Period.

 

(f)          the
Company shall mail an additional Notice and Questionnaire upon request to any Holder.

3.           Registration
Procedures. The following provisions shall apply in connection with the Shelf Registration Statement.

Company and the Guarantors shall:

(ii)         include
information regarding the Notice Holders and the methods of distribution for the Registrable Securities provided to the Company

(b)          The
Company shall advise the Initial Purchaser and the Notice Holders that have provided in writing to the Company an email address,
telephone or facsimile number and/or address for notices, and confirm such advice in writing, if requested (which notice pursuant
to clauses (ii) through (v) hereof shall be accompanied by an instruction to suspend the use of the Prospectus until
the Company shall have remedied the basis for such suspension):

 

(i)          within
one day after the Shelf Registration Statement and any amendment thereto (other than an incorporated document or as a result of

or threatening of any proceeding for that purpose;

 

(iv)        of
the receipt by the Company or any of the Guarantors of any notification with respect to the suspension of the qualification of
the Registrable Securities included therein for sale in any jurisdiction or the institution or threatening of any proceeding for
such purpose; and

 

(v)         of
the happening of any event that requires any change in the Shelf Registration Statement or the Prospectus so that, as of such date,
they (A) do not contain any untrue statement of a material fact, and (B) do not omit to state a material fact required to be stated
therein or necessary to make the statements therein (in the case of the Prospectus, in the light of the circumstances under which
they were made) not misleading.

 

    	 	5	 

     

    

 

(c)          The
Company and the Guarantors shall use commercially reasonable efforts to prevent the issuance of any order suspending the effectiveness
of the Shelf Registration Statement or the qualification of the securities therein for sale in any jurisdiction and, if issued,
to obtain as soon as possible the withdrawal thereof.

 

(d)          During
the Shelf Registration Period, the Company shall promptly deliver to each Notice Holder, without charge, as many copies of the
Prospectus (including the preliminary Prospectus, if any) included in the Shelf Registration Statement and any amendment or supplement
thereto as any such person may reasonably request. The Company and the Guarantors consent to the use of the Prospectus or any amendment
or supplement thereto by each of the foregoing in connection with the offering and sale of the Registrable Securities.

 

(e)          Prior
to any offering of the Registrable Securities pursuant to the Shelf Registration Statement, the Company and the Guarantors shall
arrange for the qualification of the Registrable Securities for sale under the laws of such U.S. jurisdictions as any Notice Holder
shall reasonably request and shall maintain such qualification in effect so long as required for such Registrable Securities; provided,
however, that in no event shall the Company or the Guarantors be obligated pursuant to this Section 3(e) to qualify
to do business in any jurisdiction where it is not then so qualified or to take any action that would subject it to service of
process in suits in any jurisdiction it is not then so subject.

 

(f)          Upon
the occurrence of any event contemplated by Section 3(b)(ii) through (v) above, the Company shall promptly (or within
the time period provided for by Section 3(h) hereof, if applicable) prepare a post-effective amendment to the Shelf Registration
Statement or an amendment or supplement to the related Prospectus or file any other required document so that, as thereafter delivered
to subsequent purchasers of the securities included therein, the Prospectus will not include an untrue statement of a material
fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading.

 

(g)          For
prescribed periods of time during which the Company or the Guarantors possess material non-public information, the disclosure of
which would have a material adverse effect on the Company, and during which it is appropriate to suspend the availability of the
Shelf Registration Statement and the related Prospectus in order to comply with applicable law, the Company shall give notice (without
notice of the nature or details of such events) to the Notice Holders that the availability of the Shelf Registration Statement
is suspended and, upon receipt of any such notice, each Notice Holder agrees (i) not to sell any Registrable Securities pursuant
to the Shelf Registration Statement until such Notice Holder’s receipt of copies of the supplemented or amended Prospectus
provided for in Section 3(f) hereof, or until it is advised in writing by the Company that the Prospectus may be used, and
has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such
Prospectus, and (ii) to hold such notice in confidence. Except in the case of a suspension of the availability of the Shelf Registration
Statement and the related Prospectus solely as the result of the filing of a post-effective amendment or supplement to the Prospectus
to add additional Selling Securityholders therein, the period during which the availability of the Shelf Registration Statement
and any Prospectus is suspended (the “Deferral Period”) shall not exceed 20 consecutive days or more than 60,
in aggregate, during any 360-day period.

 

    	 	6	 

     

    

 

(h)          The
Company and the Guarantors shall comply with all applicable rules and regulations of the Commission and shall make generally available
to their respective securityholders an earnings statement satisfying the provisions of Section 11(a) of the Act as soon as practicable
after the effective date of the Shelf Registration Statement and in any event no later than 45 days after the end of a twelve-month
period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter
commencing after the effective date of the Shelf Registration Statement.

 

(i)          The
Company may require each Holder of Registrable Securities to be sold pursuant to the Shelf Registration Statement to furnish to
the Company such information regarding the Holder and the distribution of such Registrable Securities as the Company may from time
to time reasonably require for inclusion in the Shelf Registration Statement. The Company may exclude from the Shelf Registration
Statement the Registrable Securities of any Holder that fails to furnish such information within a reasonable time after receiving
such request.

 

(j)          The
Company and the Guarantors agree to take reasonable customary actions in connection with a Holder’s sale or transfer of Registrable
Securities pursuant to the Shelf Registration Statement to the extent consistent with this Agreement.

 

4.           Registration
Expenses. The Company shall bear all expenses incurred in connection with the performance of its obligations under Sections
2 and 3 hereof and shall reimburse the Holders for the reasonable fees and disbursements of a single counsel to the
Holders, which counsel shall be selected by the Majority Holders. Each Holder shall be responsible for its respective share of
any underwriting discounts and commissions (or similar costs) and transfer taxes, if any.

 

5.           Indemnity
and Contribution.

 

(a)          The
Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Holder covered by the Shelf Registration
Statement, the Initial Purchaser, and the directors, officers and, employees of each such Holder or Initial Purchaser, each person,
if any, who controls any such Holder or the Initial Purchaser within the meaning of either Section 15 of the Act or Section 20
of the Exchange Act, and each Affiliate of each Holder and of the Initial Purchaser, from and against any and all losses, claims,
damages and liabilities (including, without limitation, reasonable attorneys’ fees and other expenses reasonably incurred
in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement
of a material fact contained in the Shelf Registration Statement as originally filed or in any amendment thereof, or in any preliminary
prospectus or the Prospectus, or in any amendment or supplement thereto, or caused by any omission or alleged omission to state
therein a material fact necessary to make the statements therein (in the case of any preliminary prospectus or the Prospectus,
in the light of the circumstances under which they were made) not misleading, and agrees to reimburse each such indemnified party,
as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Company and the Guarantors will not be liable in any such
case to the extent that such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omission based upon information relating to the party claiming indemnification and furnished to the Company
or any of the Guarantors in writing by such party claiming indemnification expressly for use therein.

 

    	 	7	 

     

    

 

(b)          Each
Holder of securities covered by the Shelf Registration Statement (including the Initial Purchaser in its capacity as a Holder)
severally and not jointly agrees to indemnify and hold harmless the Company and the Guarantors, their directors and officers who
sign the Shelf Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15
of the Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company and the Guarantors
to each such Holder, but only with reference to information relating to such Holder furnished to the Company or the Guarantors
in writing by or on behalf of such Holder expressly for use in the documents referred to in the foregoing indemnity; provided,
however, that the liability of any Holder pursuant to the indemnity in this Section 5(b) shall not be greater than the
proceeds received by such Holder upon sale of the Registrable Securities giving rise to the indemnity. This indemnity agreement
shall be acknowledged by each Notice Holder that is not an Initial Purchaser in such Notice Holder’s Notice and Questionnaire
and shall be in addition to any liability that any such Notice Holder may otherwise have.

 

(c)          In
case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity
may be sought pursuant to Section 5(a) or 5(b), such person (the “indemnified party”) shall promptly
notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying
party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent
the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements
of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying
party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the actual or potential defendants
in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different
from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory
to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action
or (iv) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel shall have been reasonably concluded (based on the advice
of counsel) to be inappropriate due to conflicts between them. It is understood that the indemnifying party shall not, in respect
of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified
parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing
by the relevant indemnified party. The indemnifying party shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party
agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified
party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party
agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement
is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying
party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No
indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder
by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.

 

    	 	8	 

     

    

 

(d)          To
the extent the indemnification provided for in Section 5(a) or 5(b) of is unavailable to an indemnified party or
insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such
paragraph shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or defending loss, claim, liability, damage or action)
(collectively “Losses”) to which such indemnified party may be subject in such proportion as is appropriate
to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other
hand, from the initial offering of the Registrable Securities and the Shelf Registration Statement which resulted in such Losses;
provided, however, that in no event shall the Initial Purchaser be responsible, in the aggregate, for any amount in excess
of the purchase discount or commission applicable to the Registrable Securities, as set forth in the Final Memorandum, nor shall
any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities
purchased by such underwriter under the Shelf Registration Statement which resulted in such Losses. If the allocation provided
by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute
in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying
party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which resulted
in such Losses as well as any other relevant equitable considerations; provided, however, that (A) in no event shall
the benefits received by any Holder be deemed to exceed, and no Holder shall be required to contribute, in the aggregate, any amount
in excess of, the amount by which the net proceeds actually received by such Holder from the sale of the Registrable Securities
exceeds the amount of any damages that such Holder has otherwise been required to pay, (B) in no event shall the benefits received
by the Initial Purchaser be deemed to exceed, and the Initial Purchaser shall not be required to contribute, in the aggregate,
any amount in excess of, the amount by which the total discounts and commissions received by the Initial Purchaser as set forth
in the Final Memorandum exceeds the amount of any damages that the Initial Purchaser has otherwise been required to pay, and (C)
in no event shall the benefits received by any underwriter be deemed to exceed, and such underwriter shall not be required to contribute,
in the aggregate, any amount in excess of, the amount by which the total underwriting discounts and commissions, as set forth on
the cover page of the Prospectus (including any related prospectus supplement) forming a part of the Shelf Registration Statement
Prospectus (including any related prospectus supplement) related to such Losses exceeds the amount of any damages that such underwriter
has otherwise been required to pay. Relative fault shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

 

    	 	9	 

     

    

 

(e)          The
parties agree that it would not be just or equitable if contribution pursuant to this Section 5 were determined by pro
rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation that
does not take account of the equitable considerations referred to in Section 5(d). Notwithstanding the provisions of this
Section 5, the Initial Purchaser shall not be required to contribute any amount in excess of the amount by which the
total price at which the Registrable Securities resold by it in the initial placement of such Registrable Securities were offered
to investors exceeds the amount of any damages that the Initial Purchaser has otherwise been required to pay by reason of such
untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or
remedies which may otherwise be available to any indemnified party at law or in equity. For purposes of this Section 5,
each person who controls the Initial Purchaser within the meaning of either Section 15 of the Act or Section 20 of the Exchange
Act and each director, officer and employee of Initial Purchaser shall have the same rights to contribution as the Initial Purchaser;
each person who controls a Holder within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each
director, officer and employee of such Holder shall have the same rights to contribution as such Holder; and each person who controls
the Company within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act and each director, officer and
employee of the Company who shall have signed the Shelf Registration Statement shall have the same rights to contribution as the
Company.

 

(f)          The
indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless
of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Holder or the Company or of any of
the indemnified persons referred to in this Section 5 and (iii) the sale by a Holder of securities covered by the Shelf
Registration Statement.

 

6.           Registration
Defaults. Each of the following events shall constitute a Registration Default:

 

(a)          if
the Shelf Registration Statement is not filed with the Commission within 30 days following the Closing Date;

 

    	 	10	 

     

    

 

(b)          if
the Shelf Registration Statement is not declared effective by the Commission within 60 days following the Closing Date, or within
90 days following the Closing Date if such Shelf Registration Statement is reviewed by the Commission;

 

(c)          if
the Shelf Registration Statement has been declared or becomes effective but ceases to be effective or usable for the offer and
sale of the Registrable Securities (other than in connection with (A) a Deferral Period or (B) as a result of a requirement to
file a post-effective amendment or supplement to the Prospectus to make changes to the information regarding Selling Securityholders
or the plan of distribution provided for therein at any time during the Shelf Registration Period) and the Company and the Guarantors
do not cure the lapse of effectiveness or usability within ten Business Days;

 

(d)          if,
at any time during the six-month period beginning on, and including, the date which is six months after the Closing Date, the Company
or the Guarantors fail to timely file any document or report that is required to be filed with the Commission pursuant to Section
13 or 15(d) of the Exchange Act, as applicable, after giving effect to all applicable grace periods thereunder and other than reports
to be filed on Form 8-K; or

 

(e)          if
the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such period pursuant
to Section 3(g) hereof; 

 

provided, however, that a Registration Default will be
deemed to end upon the day before the earlier of (i) the day on which such Registration Default has been cured or waived, and (ii)
the date the Shelf Registration Statement is no longer required to be kept effective for the Registrable Securities.

 

If a Registration Default occurs, subject
to the provisions of the Indenture, the Company will pay additional interest on the Notes to those entitled to interest payments
semi-annually in arrears on each interest payment date (“Additional Interest”), which Additional Interest will
accrue at a rate equal to 1.00% per annum of the principal amount of Notes outstanding for each day during such period that such
Registration Default has occurred and is continuing. In no event will any Additional Interest payable pursuant to a Registration
Default exceed 1.00% per year. The Company shall notify the Trustee in writing of any Additional Interest due prior to the applicable
interest payment date. If a Note ceases to be outstanding during any period for which Additional Interest is accruing, the Additional
Interest to be paid with respect to that Note will be prorated.

 

The occurrence and continuance of a Registration
Default shall not have any effect on the Company’s and Guarantors’ rights under the Indenture in respect to the right
to redeem the Notes and Guarantee.

 

7.          No
Resale of Reacquired Registrable Securities. The Company and the Guarantors agree that they will not, and will not permit their
respective subsidiaries to, resell any Notes or Warrants that they reacquire, if any.

 

    	 	11	 

     

    

 

8.           No
Inconsistent Agreements. The Company and the Guarantors have not entered into, and agree not to enter into, any agreement with
respect to securities that is inconsistent with the registration rights granted to the Holders herein.

 

9.           Rule
144A and Rule 144. So long as any Registrable Securities remain outstanding, the Company and the Guarantors shall file the
reports required to be filed by them under Rule 144A(d)(4) under the Act and the Exchange Act in a timely manner and, if at any
time the Company is not required to file such reports, it will, upon the written request of any Holder of Registrable Securities,
make available other information so long as necessary to permit sales of such Holder’s Registrable Securities pursuant to
Rule 144A of the Act. The Company covenants that it will take such further action as any Holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration
under the Act within the exemptions provided by Rules 144 and 144A of the Act (including, without limitation, the requirements
of Rule 144A(d)(4)). Upon the written request of any Holder of Registrable Securities, the Company shall deliver to such Holder
a written statement as to whether the Company and the Guarantors have complied with such requirements.

 

10.          Listing.
The Company shall use best efforts to maintain the approval of the Underlying Shares for listing on NASDAQ.

 

11.          Amendments
and Waivers. The provisions of this Agreement may not be amended, qualified, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of the Majority
Holders; provided, however, that, with respect to any matter that directly or indirectly affects the rights of the Initial
Purchaser hereunder, the Company shall obtain the written consent of the Initial Purchaser; provided, further, that no amendment,
qualification, modification, supplement, waiver or consent with respect to Section 6 hereof shall be effective as against
any Holder unless consented to in writing by such Holder; and provided, further, that the provisions of this Section
11 may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Company has obtained the written consent of the Initial Purchaser and each Holder.

 

12.          Notices.
All notices and other communications provided for or permitted hereunder shall be made in writing:

 

(a)          if
to a Holder, at the most current address given by such Holder to the Company in accordance with the provisions of the Notice and
Questionnaire or, if no Notice and Questionnaire has been provided by such Holder, to the address on file for such Holder in the
register of ownership of the Notes;

 

(b)          if
to the Initial Purchaser, initially at the addresses set forth in the Initial Purchaser Agreement; and

 

(c)          if
to the Company or any of the Guarantors, initially at the addresses set forth in the Initial Purchaser Agreement.

 

    	 	12	 

     

    

 

All such notices and communications shall
be deemed to have been duly given when received. The Initial Purchaser and the Company, on behalf of itself and of the Guarantors,
by notice to the other parties may designate additional or different addresses for subsequent notices or communications.

 

Notwithstanding the foregoing, notices given
to Holders holding Notes in book-entry form may be given through the facilities of DTC or any successor depository.

 

13.          Remedies.
The Initial Purchaser and each Holder, in addition to being entitled to exercise all rights provided to them in this Agreement,
the Indenture, the Warrant Agreement or the Initial Purchaser Agreement or granted by law, will be entitled to specific performance
of their respective rights under this Agreement. The Company and the Guarantors agree that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by them of the provisions of this Agreement and hereby agree to waive
in any action for specific performance the defense that a remedy at law would be adequate.

 

14.          Successors.
This Agreement shall inure to the benefit of and be binding upon the parties hereto, their respective successors and assigns, including,
without the need for an express assignment or any consent by the Company or the Guarantors thereto, subsequent Holders of Registrable
Securities, and the indemnified persons referred to in Section 5 hereof. The Company and the Guarantors hereby agree to
extend the benefits of this Agreement to any Holder of Registrable Securities, and any such Holder may specifically enforce the
provisions of this Agreement as if an original party hereto.

 

15.          Counterparts.
This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together
shall constitute one and the same agreement.

 

16.          Headings.
The section headings used herein are for convenience only and shall not affect the construction hereof.

 

17.          Applicable
Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York. The parties hereto
each hereby waive any right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

 

18.          Severability.
In the event that any one of more of the provisions contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision
in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended
that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law.
