COMMON STOCK PURCHASE WARRANT 
  

 
 No.
W-                     

THIS CERTIFIES that, for good and valuable consideration received,
[                                        ] or a
registered assignee (the “Holder”) is entitled, upon the terms and subject to the conditions hereinafter set forth, to acquire from ImmunoCellular Therapeutics, Ltd., a Delaware corporation (the “Corporation”), up
to [                    ] ([            ]) fully paid and nonassessable shares of common
stock, par value $0.0001, of the Corporation (“Common Stock”) at a purchase price per share (the “Exercise Price”) of One Dollar and Fifty Cents ($1.50) (the “Warrant”). 

 

	1.	Term of Warrant. 


Subject to the terms and conditions set forth herein, this Warrant shall be exercisable, in whole or in part, at any time on or after the
date hereof and at or prior to 11:59 p.m., Pacific Standard Time, on [                    ], 2013 (the “Expiration Time”).

  

	2.	Exercise of Warrant; 4.99% Exercise Limitation; Limited Net Cash Settlement Right 


(a) Exercise. The purchase rights represented by this Warrant are exercisable by the Holder, in whole or in
part, at any time and from time to time at or prior to the Expiration Time by the surrender of this Warrant and the Notice of Exercise form attached hereto duly executed to the office of the Corporation, ImmunoCellular Therapeutics, Ltd., Attention:
President, 21900 Burbank, 3rd Floor, Woodland Hills,
California 91367; facsimile: (818) 992-2908 (or such other office or agency of the Corporation as it may designate by notice in writing to the Holder at the address of the Holder appearing on the books of the Corporation), and upon payment of
the Exercise Price for the shares thereby purchased (by cash or by check or bank draft payable to the order of the Corporation); whereupon the Holder shall be entitled to receive from the Corporation a stock certificate in proper form representing
the number of shares of Common Stock so purchased. Section 2(c) below describes the limited right of the Holder under specified circumstances to exercise this Warrant by means of a “cashless exercise.” 

(b) 4.99% Exercise Limitation. 

The Corporation shall not effect any exercise of this Warrant, and the Holder shall not have the right to exercise any portion of this
Warrant, pursuant to Section 2(a) 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
person or entity acting as a group 







 
together with the Holder or any of the Holder’s affiliates), as set forth on the applicable Notice of Exercise, would beneficially own in excess of the Beneficial Ownership Limitation (as
defined below). For purposes of the preceding 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 (1) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any
of its affiliates and (2) exercise, conversion, or exchange of the unexercised, unconverted, or non-exchanged portion of any other securities of the Corporation (including, without limitation, any other warrants) subject to a limitation on
conversion, exercise, or exchange 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(b), beneficial
ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, and the determination of whether a
person or entity is an “affiliate” of the Holder shall also be made in accordance with the Exchange Act, the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations under such acts. To the
extent that the limitation contained in this Section 2(b) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any affiliates) and of which a 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 of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Corporation 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(b), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Corporation’s most recent Form 10-Q report or Form 10-K
report, as the case may be, (y) a more recent public announcement by the Corporation, or (z) any other notice by the Corporation or the Corporation’s transfer agent setting forth the number of shares of Common Stock
outstanding. Upon the written or oral request of the Holder, the Corporation 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 Corporation, 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 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon
exercise of this Warrant. 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(b) 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. 
 Notwithstanding the provisions of the immediately preceding paragraph, the Holder,
upon not less than sixty-one days’ prior written notice to the Corporation, may elect (1) to change the Beneficial Ownership Limitation to 9.9% of the number of shares of Common Stock outstanding immediately after giving effect to the
issuance of shares of Common Stock issuable upon exercise of this Warrant or (2) to eliminate the Beneficial Ownership Limitation in its entirety.

 (c) Limited Net Cash Settlement Right. 

If this Warrant is exercised on or after 90 days from the date hereof and if as of the date of such Warrant exercise there is no
effective registration statement under the Securities Act registering, or the prospectus contained therein is not available for, the issuance or resale of the shares of Common Stock upon the exercise of this Warrant, then this Warrant may instead be
exercised, upon the Holder’s election in the Notice of Exercise, by means of a “cashless exercise” in which the Holder shall be entitled to receive a certificate for the number of shares of Common Stock 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 Notice of
Exercise; provided that, for purposes of this Section 2(c), the date of such Warrant exercise shall be deemed to be the date on which the Corporation actually receives from the Holder the executed Notice of Exercise, either by facsimile
transmission or by mail;
			
	(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 on a national securities exchange, the daily volume-weighted average price of the Common Stock for such date (or the nearest preceding date) on the national
securities exchange on which the Common Stock is then listed as reported by Bloomberg L.P. (based on a trading day from 9:30 a.m. (New York City time) to 4:00 p.m. (New York City time), (b) if the Common Stock is not then listed on a national
securities exchange, 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 a national securities
exchange or 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 Corporation. 

Except as specifically set forth in the preceding portions of this Section 2(c), under no circumstances will the Corporation be
required to net cash settle this Warrant upon its exercise. 
  

	3.	Issuance of Shares; No Fractional Shares or Scrip. 


Certificates for shares purchased hereunder shall be delivered to the Holder by the Corporation’s transfer agent at the
Corporation’s expense within a reasonable time after the date on which this Warrant shall have been exercised in accordance with the terms hereof. Each certificate so delivered shall be in such denominations as may be requested by the Holder
and shall be registered in the name of the Holder or, subject to applicable laws, such other name as shall be requested by the Holder. If, upon exercise of this Warrant, fewer than all of the shares of Common Stock evidenced by this Warrant are
purchased prior to the Expiration Time, one or more new Warrants substantially in the form of, and on the terms in, this Warrant will be issued for the remaining number of shares of Common Stock not purchased upon exercise of this Warrant. The
Corporation hereby represents and warrants that all shares of Common Stock which may be issued upon the exercise of this Warrant will, upon such exercise, be duly and validly authorized and 

 

 3 








 
issued, fully paid, and nonassessable and free from all taxes, liens, and charges in respect of the issuance thereof (other than liens or charges created by or imposed upon the Holder). The
Corporation agrees that the shares so issued shall be and will be deemed to be issued to such Holder as the record owner of such shares as of the close of business on the date on which this Warrant shall have been surrendered for exercise in
accordance with the terms hereof. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. With respect to any fraction of a share called for upon the exercise of this Warrant, an amount equal
to such fraction multiplied by the then current price at which each share may be purchased hereunder shall be paid in cash to the Holder of this Warrant. 
  

	4.	Registration Rights. 


Pursuant to the terms of the Registration Rights Agreement between the Corporation and the Holder signed in connection with the issuance
of this Warrant, certain registration rights apply to the shares of Common Stock issuable upon exercise of this Warrant. See the Registration Rights Agreement for a full description of the registration rights applicable to such shares of Common
Stock and the limitations on such rights. 
  

	5.	Charges, Taxes, and Expenses. 


Issuance of certificates for shares of Common Stock upon the exercise of this Warrant 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 Corporation, 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 shares of Common Stock are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by an
Assignment Form to be provided by the Corporation duly executed by the Holder. 
  

	6.	No Rights as a Stockholder. 


This Warrant does not entitle the Holder to any voting rights or other rights as a stockholder of the Corporation prior to the exercise
of this Warrant. 
  

	7.	Exchange and Registry of Warrant. 


This Warrant is exchangeable, upon the surrender hereof by the Holder at the above-mentioned office or agency of the Corporation, for a
new Warrant of like tenor and dated as of such exchange. The Corporation shall maintain at the above-mentioned office or agency a registry showing the name and address of the registered Holder of this Warrant. This Warrant may be surrendered for
exchange, transfer, or exercise, in accordance with its terms, at such office or agency of the Corporation, and the Corporation shall be entitled to rely in all respects, prior to written notice to the contrary, upon such registry. 

 

	8.	Loss, Theft, Destruction, or Mutilation of Warrant. 


Upon receipt by the Corporation of evidence reasonably satisfactory to it of the loss, theft, destruction, or mutilation of this Warrant
and in case of loss, theft, or destruction of indemnity or security reasonably satisfactory to it, and upon reimbursement to the Corporation of all reasonable expenses incidental thereto, and upon surrender and cancellation of this Warrant, if
mutilated, the Corporation will make and deliver a new Warrant of like tenor and dated as of such cancellation, in lieu of this Warrant. 
  

 4 









	9.	Saturdays, Sundays and Holidays. 


If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday,
a Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday. 
  

	10.	Merger, Sale of Assets and Similar Transactions. 


If at any time the Corporation proposes to merge or consolidate with or into any other corporation, effect any reorganization, or sell or
convey all or substantially all of its assets to any other entity, then, as a condition of such reorganization, consolidation, merger, sale or conveyance, the Corporation or its successor, as the case may be, shall enter into a supplemental
agreement to make lawful and adequate provision whereby the Holder shall have the right to receive, upon exercise of this Warrant, the kind and amount of equity securities which would have been received upon such reorganization, consolidation,
merger, sale or conveyance by a Holder of a number of shares of Common Stock equal to the number of shares issuable upon exercise of this Warrant immediately prior to such reorganization, consolidation, merger, sale, or conveyance. The Corporation
shall give the Holder of this Warrant ten business days’ prior written notice of the proposed effective date of any such merger, consolidation, reorganization, sale or conveyance, and the Corporation shall also give the Holder of this Warrant
ten business days’ prior written notice of the commencement of the Corporation’s voluntary or involuntary dissolution, liquidation or winding up. If the property to be received upon such merger, consolidation, reorganization, sale or
conveyance is not equity securities, and if this Warrant has not been exercised by or on the effective date of such transaction, it shall terminate. 
  

	11.	Subdivision, Combination, Reclassification, Conversion and Similar Events. 


If the Corporation at any time shall by subdivision, combination, reclassification of securities or otherwise, change the Common Stock
into the same or a different number of securities of any class or classes, this Warrant shall thereafter entitle the Holder to acquire such number and kind of securities as would have been issuable in respect of the Common Stock (or other securities
which were subject to the purchase rights under this Warrant immediately prior to such subdivision, combination, reclassification or other change) as the result of such change if this Warrant had been exercised in full for cash immediately prior to
such change. The Exercise Price hereunder shall be adjusted if and to the extent necessary to reflect such change. If the Common Stock or other securities issuable upon exercise hereof are subdivided or combined into a greater or smaller number of
shares of such security, the number of shares issuable hereunder shall be proportionately increased or decreased, as the case may be, and the Exercise Price shall be proportionately reduced or increased, as the case may be, in both cases according
to the ratio which the total number of shares of such security to be outstanding immediately after such event bears to the total number of shares of such security outstanding immediately prior to such event. The Corporation shall give the Holder
prompt written notice of any change in the type of securities issuable hereunder, any adjustment of the Exercise Price for the securities issuable hereunder, and any increase or decrease in the number of shares issuable hereunder. 

 

	12.	Subsequent Rights Offerings and Pro Rata Distributions. 


(a) If the Corporation, at any time while this Warrant is outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to the Holder) 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 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 
  

 5 








 
the number of shares of 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 Corporation 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. 

(b) If the Corporation, at any time while this Warrant is outstanding, shall distribute to all holders of Common Stock (and not to the
Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security other than Common Stock, 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
Common Stock as determined by the Board of Directors of the Corporation 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. 

(c) The Corporation shall give the Holder ten business days’ prior written notice of the proposed effective date of any such
transaction that is described in Section 12(a) or 12(b). 
  

	13.	Transferability; Compliance with Securities Laws. 


(a) This Warrant may not be transferred or assigned in whole or in part without compliance with all applicable United States, state, and
foreign securities laws by the transferor and transferee (including the delivery of investment representation letters and legal opinions reasonably satisfactory to the Corporation, if requested by the Corporation). Subject to such restrictions,
prior to the Expiration Time, this Warrant and all rights hereunder are transferable by the Holder hereof, in whole or in part, at the office or agency of the Corporation referred to in Section 2 above. Any such transfer shall be made in person
or by the Holder’s duly authorized attorney, upon surrender of this Warrant together with the Assignment Form attached hereto properly endorsed. 

(b) The Holder of this Warrant, by acceptance hereof, acknowledges that this Warrant and the Common Stock issuable upon exercise hereof
are being acquired solely for the Holder’s own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell, or otherwise dispose of this Warrant or any shares of Common Stock to be issued upon
exercise hereof except under circumstances that will not result in a violation of the Securities Act or any state or foreign securities laws. Upon exercise of this Warrant, the Holder shall, if requested by the Corporation, confirm in writing, in a
form satisfactory to the Corporation, that the shares of Common Stock so purchased are being acquired solely for Holder’s own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale.

 (c) The Common Stock has not been registered under the Securities Act, and this Warrant may not be exercised except by
(1) the original purchaser of this Warrant from the Corporation or (2) an “accredited investor” as defined in Rule 501(a) under the Securities Act. Each certificate representing shares of Common Stock issued on exercise of this
Warrant or other securities issued in respect of such Common Stock upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall be stamped or otherwise imprinted with a legend substantially in the following
form (in addition to any other legend required under applicable securities laws): 
 THE SHARES OF COMMON STOCK EVIDENCED HEREBY HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS COVERING ANY SUCH TRANSACTION OR UNLESS THE CORPORATION SHALL HAVE RECEIVED AN OPINION OF ITS COUNSEL THAT REGISTRATION OF SUCH SHARES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF
APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.
