Titan
Pharmaceuticals, Inc.


 











	Warrant Shares: [_______	Issue
Date: January ___, 2021






 


THIS
COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, _____________ or its assigns
(the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter
set forth, at any time on or after the date hereof (the “Initial Exercise Date”) and on or prior to 5:00 p.m.
(New York City time) on July ___, 2026[1]
(the “Termination Date”) but not thereafter, to subscribe for and purchase from Titan Pharmaceuticals, Inc.,
a Delaware corporation (the “Company”), up to ______ shares (as subject to adjustment hereunder, the “Warrant
Shares”) of Common Stock. The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise
Price, as defined in Section 2(b).


 


Section
1.Definitions. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that
certain Securities Purchase Agreement (the “Purchase Agreement”), dated January 14, 2021, among the Company
and the purchasers signatory thereto.


 


Section
2.Exercise.


 


a)                 
Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part,
at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of
a duly executed PDF copy submitted by e-mail (or e-mail attachment) of the Notice of Exercise in the form annexed hereto (the
 “Notice of Exercise”). Within the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising
the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid, the Holder
shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer or cashier’s
check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the
applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other
type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the
Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant
Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant
to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to
the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available
hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal
to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing the number of
Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within
one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and
agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder,
the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face
hereof.

Exercise Price. The exercise price per share of Common Stock under this Warrant shall be $3.55, subject to
adjustment hereunder (the “Exercise Price”).


 


c)                 
Cashless Exercise. If at any time after the six month anniversary of the Closing Date, there is no effective registration
statement registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder, then this Warrant
may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall
be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


(A)
= as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice
of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both
executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours”
(as defined in Rule 600(b)(68) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the
option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise
or (z) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s
execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours”
on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular
trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice
of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered
pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;


 


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


 


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


 






    	2 



     


    

 


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


 


“Bid
Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common
Stock is then listed or quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest
preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based
on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b)  if OTCQB or OTCQX is not a
Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or
OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the
Common Stock are then reported on the Pink Open Market (or a similar organization or agency succeeding to its functions of reporting
prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market
value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority
in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall
be paid by the Company.


 


“VWAP”
means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then
listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest
preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based
on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b)  if OTCQB or OTCQX is not a
Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or
OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the
Common Stock are then reported on the Pink Open Market (or a similar organization or agency succeeding to its functions of reporting
prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market
value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Purchasers of a majority
in interest of the Securities then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall
be paid by the Company.

Notwithstanding
anything herein to the contrary, on the Termination Date, this Warrant shall be automatically exercised via cashless exercise
pursuant to this Section 2(c).


 


		d)	Mechanics
                                         of Exercise.



 


i.           
Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted
by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with
The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company
is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the
Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder
without volume or manner-of-sale limitations pursuant to Rule 144 (assuming cashless exercise of the Warrants), and otherwise
by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee,
for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder
in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company of the
Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company and (iii) the number
of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise (such date,
the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for
all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised,
irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other than
in the case of a cashless exercise) is received within the earlier of (i) two (2) Trading Days and (ii) the number of Trading
Days comprising the Standard Settlement Period following delivery of the Notice of Exercise. If the Company fails for any reason
to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall
pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise
(based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20
per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant
Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a
transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used
herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading
Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the
Notice of Exercise.


 






    	4 



     


    

 


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


 


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


 


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


 






    	5 



     


    

 


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


 


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


 


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


 






    	6 



     


    

 


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

Section
3.Certain Adjustments.


 


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


 


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


 


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


 






    	8 



     


    

 


d)                 
Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly,
in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of
the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is
effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in
one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without
limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons
whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares
of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons
making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”),
then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would
have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction, at the option of the
Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock
of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration
(the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of
shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard
to any limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the
Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received
in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon
any exercise of this Warrant following such Fundamental Transaction. Notwithstanding anything to the contrary, the Company or
any Successor Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within
30 days after, the consummation of the Fundamental Transaction (or, if later, the date of the public announcement of the applicable
Fundamental Transaction), purchase this Warrant from the Holder by paying to the Holder an amount in cash equal to the Black Scholes
Value (as defined below) of the remaining unexercised portion of this Warrant on the date of the consummation of such Fundamental
Transaction; provided, however, if the Fundamental Transaction is not within the Company’s control, including not approved
by the Company’s Board of Directors, the Holder shall only be entitled to receive from the Company or any Successor Entity
the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of
this Warrant, that is being offered and paid to the holders of Common Stock of the Company in connection with the Fundamental
Transaction, whether that consideration be in the form of cash, stock or any combination thereof, or whether the holders of Common
Stock are given the choice to receive from among alternative forms of consideration in connection with the Fundamental Transaction;
provided, further, that if holders of Common Stock are not offered or paid and consideration in such Fundamental Transaction,
such holders of Common Stock will be deemed to have received common stock of the Successor Entity (which entity may be the Company
following such Fundamental Transaction) in such Fundamental Transaction. “Black Scholes Value” means the value of
this Warrant based on the Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P.
(“Bloomberg”) determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes
and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the
date of the public announcement of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility
equal to the greater of (i) 100% and (ii) the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading
Day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share
used in such calculation shall be the greater of (i) the sum of the price per share being offered in cash, if any, plus the value
of any non-cash consideration, if any, being offered in such Fundamental Transaction and (ii) the greater of (x) the last VWAP
immediately prior to the public announcement of such Fundamental Transaction and (y) the last VWAP immediately prior to the consummation
of such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement
of the applicable Fundamental Transaction and the Termination Date. The payment of the Black Scholes Value will be made by wire
transfer of immediately available funds (or such other consideration) within five Business Days of the Holder’s election
(or, if later, on the effective date of the Fundamental Transaction). The Company shall cause any successor entity in a Fundamental
Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations
of the Company under this Warrant in accordance with the provisions of this Section 3(e) pursuant to written agreements in form
and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Fundamental
Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for
a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of
Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this
Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such
shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental
Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being
for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction),
and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction,
the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction,
the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise
every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with the same effect
as if such Successor Entity had been named as the Company herein.

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


 


f)                  
Notice to Holder.


 


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


 


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

Section
4.Transfer of Warrant.


 


a)                 
Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section
4(d) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including,
without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal
office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached
hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making
of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants
in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument
of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant
in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which
the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned
in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.


 


b)                 
New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid
office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued,
signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved
in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or
Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated
the original issue date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.


 


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


 






    	11 



     


    

 


d)                 
Transfer Restrictions. If, at
the time of the surrender of this Warrant in connection with any transfer of this Warrant,
the transfer of this Warrant shall not be either (i) registered pursuant to an effective registration statement
under the Securities Act and under applicable state securities or blue sky laws
or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information requirements pursuant
to Rule 144, the Company may require, as a condition of allowing such transfer, that the Holder or transferee of this Warrant,
as the case may be, comply with the provisions of Section 4.1 of the Purchase Agreement.


 


e)                 
Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring
this Warrant and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and
not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act
or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.


 


Section
5.Miscellaneous.


 


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


 


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


 


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


 






    	12 



     


    

 


d)                 
Authorized Shares.


 


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


 


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


 


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


 


e)                 
Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant
shall be determined in accordance with the provisions of the Purchase Agreement.


 


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


 






    	13 



     


    

 





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


 


h)                 
Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the
Company shall be delivered in accordance with the notice provisions of the Purchase Agreement.


 


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


 


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


 


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


 


l)                  
Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the
Company and the Holder.


 


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


 










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