Warrant Shares: [_________]

 

THIS COMMON STOCK PURCHASE
WARRANT (the “Warrant”) certifies that, for value received, [_____________________] (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 November [__], 2014 the “Initial Exercise Date”) and on or prior to the close of business on November
[__], 2017 (the “Termination Date”) but not thereafter, to subscribe for and purchase from 3DICON Corporation,
an Oklahoma corporation (the “Company”), up to [_________] shares (the “Warrant Shares”)
of Common Stock.

 

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 November [__], 2013, among the Company and the purchaser 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 (or such other office or
agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing
on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto; and, within three
(3) Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the
aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank
or, if available, pursuant to the cashless exercise procedure specified in Section 2(c) below. 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 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 Form within
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.

b)         Exercise
Price. The exercise price per share of the Common Stock under this Warrant shall be $0.0055, which exercise price is subject
to adjustment hereunder (the “Exercise Price”).

 

c)         Cashless
Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained
therein is not available for the issuance of the Warrant Shares to the Holder and all of the Warrant Shares are not then registered
for resale by Holder into the market at market prices from time to time on an effective registration statement for use on a continuous
basis (or the prospectus contained therein is not available for use), then this Warrant shall 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 certificate for the
number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

 

		(A) = 	the VWAP on the Trading Day immediately preceding the
date on which Holder elects to exercise this Warrant by means of a “cashless exercise,” as set forth in the applicable
Notice of Exercise;

 

		(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.

 

“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 the OTC Bulletin Board is not a Trading Market,
the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board,
(c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are
then reported in the “Pink Sheets” published by Pink OTC Markets, Inc. (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
Holders 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.

d)           Mechanics
of Exercise.

 

i.            Delivery
of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the Transfer Agent to the
Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company through its Deposit or Withdrawal
at Custodian (“DWAC”) system if the Company is then a participant in such system and either (A) there is an
effective Registration Statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder or
(B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery to the address specified by the Holder
in the Notice of Exercise by the date that is five (5) Trading Days after the latest of (A) the delivery to the Company of the
Notice of Exercise Form, (B) surrender of this Warrant (if required) and (C) payment of the aggregate Exercise Price as set forth
above (including by cashless exercise, if permitted) (such date, the “Warrant Share Delivery Date”). This Warrant
shall be deemed to have been exercised on the first date on which all of the foregoing have been delivered to the Company. The
Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed
to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with payment
to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if
any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having been paid.

 

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 certificate or certificates representing Warrant
Shares, deliver to Holder a new Warrant evidencing the rights of 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 a certificate or the certificates representing
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.         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.

 

v.           Charges,
Taxes and Expenses. Issuance of certificates for 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 certificate, all of which taxes and expenses shall
be paid by the Company, and such certificates 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 certificates for 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.

 

    	3

    	 

    

 

vi.         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.

 

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), 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 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 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. 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. 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 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 two Trading Days 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 since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial
Ownership Limitation” shall be 4.9% 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 not less than 61 days’
prior 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 such increase or decrease 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. If the Company, at any time while the Warrant is outstanding, shall issue rights, options or warrants to
all holders of Common Stock (and not to the Holders) entitling them to subscribe for or purchase shares of Common Stock at a price
per share less than the VWAP on the record date mentioned below, then the Exercise Price shall be multiplied by a fraction, of
which the denominator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options
or warrants plus the number of additional shares of Common Stock offered for subscription or purchase, and of which the numerator
shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights, options or warrants plus
the number of shares which the aggregate offering price of the total number of shares so offered (assuming receipt by the Company
in full of all consideration payable upon exercise of such rights, options or warrants) would purchase at such VWAP. Such adjustment
shall be made whenever such rights, options or warrants are issued, and shall become effective immediately after the record date
for the determination of stockholders entitled to receive such rights, options or warrants.

 

c)         Pro
Rata Distributions. If the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common
Stock (and not to the Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants
to subscribe for or purchase any security, then in each such case the Exercise Price shall be adjusted by multiplying the Exercise
Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution
by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of which the numerator
shall be such VWAP on such record date less the then per share fair market value at such record date of the portion of such assets
or evidence of indebtedness so distributed applicable to one outstanding share of the Common Stock as determined by the Board of
Directors in good faith. In either case the adjustments shall be described in a statement provided to the Holder of the portion
of assets or evidences of indebtedness so distributed or such subscription rights applicable to one share of Common Stock. Such
adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned
above.

 

    	5

    	 

    

 

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, (v) the Company, directly or indirectly, in one or more related transactions
consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization,
recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other Person or group
of Persons 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, in the event of a Fundamental Transaction that is (1) an all cash transaction,
(2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act, or (3) a Fundamental Transaction involving
a person or entity not traded on a national securities exchange, including, but not limited to, the Nasdaq Global Select Market,
the Nasdaq Global Market, or the Nasdaq Capital Market, the Company or any Successor Entity (as defined below) shall, at the Holder’s
option, exercisable at any time within 30 days after the consummation of the Fundamental Transaction, purchase this Warrant from
the Holder by paying to the Holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion of this
Warrant on the date of the consummation of 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 100% and 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 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 (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 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 and the other Transaction Documents 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 of this Warrant, 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 and the other Transaction Documents 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 and the other Transaction Documents with the same effect
as if such Successor Entity had been named as the Company herein.

 

    	6

    	 

    

 

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
mail to the Holder a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts
requiring such adjustment.

 

    	7

    	 

    

 

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 mailed to the Holder at its last
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 mail such notice or any defect therein or in the mailing thereof shall
not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice provided
hereunder 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.
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. 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.

 

    	8

    	 

    

 

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 initial
issuance date set forth on the first page of this Warrant and shall be identical with this Warrant except as to the number of Warrant
Shares issuable pursuant thereto.

 

c)         Warrant
Register. The 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.

 

Section 5.          Miscellaneous.

 

a)         No
Rights as Stockholder Until Exercise. 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).

 

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

 

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

 

d)         Authorized
Shares.

 

The Company
covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient
number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant.
The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged
with the duty of executing stock certificates to execute and issue the necessary certificates for the 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).

 

    	9

    	 

    

 

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.

 

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 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 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 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 Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of 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.

 

    	10

    	 

    

 

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.

is conducting a private placement offering of up to 500,000 shares of Series A Convertible Preferred Stock (as further described
herein below);

 

WHEREAS, the Company
intends to accept subscriptions from multiple investors without having to reach a minimum offering amount or a minimum investment
amount; and

 

WHEREAS, Investor desires
to purchase and receive from the Company and the Company desires to issue and sell to Investor, Series A Convertible Preferred
Stock (as further described herein below) in consideration of Investor’s payment of the Purchase Price to the Company pursuant
to the terms of this Agreement.

 

NOW, THEREFORE, based
upon the foregoing and the mutual promises in this Agreement, the parties agree as follows:

 

1.          Investment.
In exchange for Investor’s cash payment in the amount set forth on the signature page hereto (the “Purchase Price”),

preferences and limitations as set forth in the Certificate of Designation, in the form of Exhibit A hereto (“Certificate
of Designation”); and (ii) a warrant to purchase fifty (50) shares of the Company’s common stock, par value $0.0002

Price, the Company shall deliver to the Investor the certificates evidencing the shares of Series A Preferred issued pursuant
to this Agreement and a Common Stock Purchase Warrant, in the form of Exhibit B hereto (the “Warrant”),
evidencing the warrant to purchase shares of Common Stock issued pursuant to this Agreement. For purposes of this Agreement the

and the shares of Common Stock that may be purchased upon exercise of the Warrants shall be collectively known as the “Securities”.

 

2.          Termination.
In the event the sale of the Securities is not consummated for any reason, this Agreement and any other agreement entered into
between the Investor and the Company shall thereafter have no force or effect, and the Company shall promptly return or cause
to be returned to the Investor the Purchase Price remitted to the Company, without deduction therefrom.

 

3.          Representations
by Investor. In consideration of the Company’s issuance of The Securities, Investor makes the following representations
and warranties to the Company and to its principals, which warranties and representations shall survive the issuance of The Securities
by the Company:

 

    	 

    	 

    

 

(a)          Prior
to the time of purchase of any of The Securities, Investor has carefully reviewed this Agreement, and the Company’s filings
with the Securities and Exchange Commission (the foregoing materials, together with this Agreement and any documents which may
have been made available upon request as reflected therein, collectively referred to as the “Public Information”).
Investor has had the opportunity to ask questions and receive any additional information from persons acting on behalf of the Company
to verify Investor’s understanding of the terms thereof and of the Company’s business and status thereof.

 

(b)          Investor
acknowledges that Investor has not seen, received, been presented with, or been solicited by any leaflet, public promotional meeting,
newspaper or magazine article or advertisement, radio or television advertisement, or any other form of advertising or general
solicitation with respect to the Securities.

 

(c)          The
Securities are being purchased for Investor’s own account for long-term investment and not with a view to immediately re-sell
the Securities. No other person or entity will have any direct or indirect beneficial interest in, or right to, the Securities.
Investor or its agents or investment advisors have such knowledge and experience in financial and business matters that will enable
Investor to utilize the information made available to it in connection with the purchase of the Securities to evaluate the merits
and risks thereof and to make an informed investment decision.

 

(d)          Investor
hereby acknowledges that the issuance of the Securities has not been reviewed by the United States Securities and Exchange Commission
(the “SEC”) nor any state regulatory authority since the issuance of the Securities is intended to be exempt
from the registration requirements of Section 5 of the Securities Act, pursuant to Regulation D. Investor acknowledges that the
Securities have not been registered under the Securities Act or qualified under the under the securities laws of any state or other
jurisdiction or any other regulatory authority, or any other applicable blue sky laws, in reliance, in part, on Investor’s
representations, warranties and agreements made herein.

 

(e)          Investor
represents, warrants and agrees that the Company and the officers of the Company (the “Company’s Officers”)
are under no obligation to register or qualify the Securities under the Securities Act or under any state securities law, or to
assist the undersigned in complying with any exemption from registration and qualification.

 

(f)           Investor
represents that Investor meets the criteria for participation because: (i) Investor has a preexisting personal or business relationship
with the Company or one or more of its partners, officers, directors or controlling persons; or (ii) by reason of Investor’s
business or financial experience, or by reason of the business or financial experience of its financial advisors who are unaffiliated
with, and are not compensated, directly or indirectly, by the Company or any affiliate or selling agent of the Company, Investor
is capable of evaluating the risk and merits of an investment in the Securities and of protecting its own interests.

 

    	2

    	 

    

 

(g)          Investor
represents that Investor is an “accredited investor” within the meaning of Rule 501 of Regulation D under the Securities
Act as indicated by the Investor’s responses to the questions contained in the Certificate of Accredited Investor Status
attached hereto as Exhibit C, and that the Investor is able to bear the economic risk of an investment in the Securities.

 

(h)          Investor
understands that the Securities are illiquid, and until registered with the SEC, or an exemption from registration becomes available,
cannot be readily sold as there will not be a public market for them, and that Investor may not be able to sell or dispose of the
Securities, or to utilize the Securities as collateral for a loan. Investor must not purchase the Securities unless Investor has
liquid assets sufficient to assure Investor that such purchase will cause it no undue financial difficulties, and that Investor
can still provide for current and possible personal contingencies, and that the commitment herein for the Securities, combined
with other investments of Investor, is reasonable in relation to its net worth.

 

(i)           Investor
understands that the right to transfer the Securities will be restricted unless the transfer is not in violation of the Securities
Act, and any other applicable state securities laws (including investment suitability standards), that the Company will not consent
to a transfer of any of The Securities unless the transferee represents that such transferee meets the financial suitability standards
required of an initial participant, and that the Company has the right, in its absolute discretion, to refuse to consent to such
transfer.

 

(j)           Investor
has been advised to consult with its own attorney or attorneys regarding all legal matters concerning an investment in the Company
and the tax consequences of purchasing the Securities, and has done so, to the extent Investor considers necessary.

 

(k)          Investor
acknowledges that the tax consequences of investing in the Company will depend on particular circumstances, and neither the Company,
the Company’s Officers, any other investors, nor the partners, shareholders, members, managers, agents, officers, directors,
employees, affiliates or consultants of any of them, will be responsible or liable for the tax consequences to Investor of an investment
in the Company. Investor will look solely to and rely upon its own advisers with respect to the tax consequences of this investment.

 

(l)           Investor
acknowledges that some of the information provided by the Company in connection with the purchase of the Securities constitutes
“material non-public information” within the meaning of Rule 10b-5 of the Exchange Act. Investor acknowledges and agrees
that Investor is prohibited from any buying or selling of the Company’s securities on the basis of this material non-public
information until after the information either becomes publicly available by the Company (such as in a Current Report on Form 8-K
or in the Company’s Form 10-K or Form 10-Q) or ceases to be material, and in no event for at least thirty (30) days from
the date hereof. Investor acknowledges that it is aware of the restrictions of applicable securities laws, including Regulation
FD and Sections 9 and 10 of the Exchange Act and Rule 10b-5 under the Exchange Act, relating to the trading in securities of an
issuer, including while in possession of material non public information regarding that issuer.

 

    	3

    	 

    

 

(m)         All
information which Investor has provided to the Company concerning Investor, including but not limited to, its financial position
and its knowledge of financial and business matters, is truthful, accurate, correct, and complete as of the date set forth herein.

IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

Investor hereby represents that the address of the Investor furnished by Investor on the signature page hereof is the Investor’s
principal residence if Investor is an individual or its principal business address if it is a corporation or other entity.
