Original Issue Date: September 6, 2016             
         


 Smith Micro Software, Inc., a Delaware corporation (the “Company”),
hereby certifies that, for value received, or its permitted registered assigns (the “Holder”), is entitled to purchase from the Company up to a total of 850,000 shares of common stock, $0.001 par value per share (the “Common
Stock”), of the Company (each such share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise price per share equal to $2.74 per share (as adjusted from time to time as provided in
Section 9 herein, the “Exercise Price”), at any time and from time to time on or after the date hereof (the “Original Issue Date”) and through and including 5:30 P.M., New York City time, on the five
(5) year anniversary of the Original Issue Date (the “Expiration Date”), and subject to the following terms and conditions: 
 This
Warrant is granted in connection with that certain Note and Warrant Purchase Agreement, dated September 2, 2016, by and among the Company and the Purchasers identified therein (the “Purchase Agreement”). This Warrant and the
Warrant Shares issuable pursuant to this Warrant shall be deemed Registrable Securities for purposes of the Registration Rights Agreement. 
 1.
Definitions. In addition to the terms defined elsewhere in this Warrant, capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. 

  
 - 1 - 








 2. Registration of Warrants. 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 (which shall include the initial Holder or, as the case may be, any registered assignee to which this Warrant is permissibly assigned hereunder)
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. 
 3. Registration of Transfers. Subject to compliance with all applicable securities laws, the Company shall register the transfer of all
or any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, with the Form of Assignment attached as Schedule 2 hereto duly completed and signed, to the Company at its address specified in the Purchase Agreement and
(x) delivery, at the request of the Company, of an opinion of counsel reasonably satisfactory to the Company to the effect that the transfer of such portion of this Warrant may be made pursuant to an available exemption from the registration
requirements of the Securities Act and all applicable state securities or blue sky laws and (y) delivery by the transferee of a written statement to the Company certifying that the transferee is an “accredited investor” as defined in
Rule 501(a) under the Securities Act, to the Company at its address specified in the Purchase Agreement. Upon any such registration or transfer, a new Warrant to purchase Common Stock in substantially the form of this Warrant (any such new Warrant,
a “New Warrant”) evidencing the portion of this Warrant so transferred shall be issued to the transferee, and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the
transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations in respect of the New Warrant that the Holder has in respect of this Warrant. The
Company shall prepare, issue and deliver at its own expense any New Warrant under this Section 3. 
 4. Exercise and Duration of Warrant. 

(a) All or any part of this Warrant shall be exercisable by the registered Holder in any manner permitted by Section 10 of this Warrant at
any time and from time to time on or after the Original Issue Date and through and including 5:30 P.M., New York City time, on the Expiration Date, subject to the conditions and restrictions contained in this Warrant. At 5:30 P.M., New York City
time, on the Expiration Date, the portion of this Warrant not exercised prior thereto shall be and become void and of no value and this Warrant shall be terminated and no longer outstanding. 

(b) The Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached as Schedule 1 hereto
(the “Exercise Notice”), completed and duly signed, and (ii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised (which may take the form of a “cashless exercise”
if so indicated in the Exercise Notice and if a “cashless exercise” may occur at such time pursuant to Section 10 below). The date on which the Exercise Notice is delivered to the Company (as determined in accordance with the notice
provisions hereof) is an “Exercise Date.” Within two (2) days on which the NASDAQ exchange is open for trading (a “Trading Day”) following the delivery of the Exercise Notice (the “Payment
Deadline”), the Holder shall make payment with respect to the Exercise Price for the number of Warrant Shares as to which this Warrant is being 

  
 - 2 - 








 
exercised; provided that the Company’s obligations to deliver such Warrant Shares shall be delayed on a day-for-day basis each day after the Payment Deadline such payment of the Exercise
Price is not paid. 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 Exercise Notice is delivered to the Company. Execution and delivery of the Exercise Notice shall have the same effect as
cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares, if any. 
 5.
Delivery of Warrant Shares. 
 (a) Subject to Section 4(b), upon exercise of this Warrant, the Company shall promptly (but in no
event later than 5:30 P.M., New York City time, on the second (2nd) Trading Day after the Exercise Date (or the third (3rd) Trading Day if the last of the Exercise Notice, the Exercise Price (if applicable) and opinion of counsel referred
to below in this Section 5(a) (if applicable) is delivered after 5:00 P.M., New York City time, on the Exercise Date) (such time, the “Delivery Deadline”) issue or cause to be issued and cause to be delivered to or upon the
written order of the Holder and in such name or names as the Holder may designate (provided that, if the Registration Statement is not effective and the Holder directs the Company to deliver a certificate for the Warrant Shares in a name other than
that of the Holder or an Affiliate of the Holder, it shall deliver to the Company on the Exercise Date an opinion of counsel reasonably satisfactory to the Company to the effect that the issuance of such Warrant Shares in such other name may be made
pursuant to an available exemption from the registration requirements of the Securities Act and all applicable state securities or blue sky laws), (i) a certificate for the Warrant Shares issuable upon such exercise, free of restrictive
legends, or (ii) an electronic delivery of the Warrant Shares to the Holder’s account at the Depository Trust Company (“DTC”) or a similar organization, unless in the case of clause (i) and (ii) a registration
statement covering the resale of the Warrant Shares and naming the Holder as a selling stockholder thereunder is not then effective or the Warrant Shares are not freely transferable without volume and manner of sale restrictions pursuant to Rule 144
under the Securities Act, in which case such Holder shall receive a certificate for the Warrant Shares issuable upon such exercise with appropriate restrictive legends. The Holder, or any Person permissibly so designated by the Holder to receive
Warrant Shares, shall be deemed to have become the holder of record of such Warrant Shares as of the Exercise Date with respect thereto. If the Warrant Shares can be issued without restrictive legends, the Company shall, upon the written request of
the Holder, use its best efforts to deliver, or cause to be delivered, Warrant Shares hereunder electronically through DTC or another established clearing corporation performing similar functions, if available. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed. 

(b) If by the Delivery Deadline, the Company has failed to comply with Section 5(a), and if after such Delivery Deadline and prior to the
receipt of such Warrant Shares, the Holder purchases (in an open market transaction) 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


  
 - 3 - 








 
exercise (a “Buy-In”), then the Company shall, within three (3) Trading Days after the Company receives the Holder’s written request and in the Holder’s sole
discretion, either: 
 (i) at the option of the Holder, 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; or 
 (ii) promptly honor its obligation to deliver to the Holder such Warrant Shares and pay cash to the Holder in
an amount equal to the excess (if any) of Holder’s total purchase price (including brokerage commissions, if any, that are reasonably documented in Holder’s written request) for the shares of Common Stock so purchased in the Buy-In over
the product of (A) the number of shares of Common Stock purchased in the Buy-In, times (B) the Closing Sale Price on the date the Warrant was exercised. 

(c) To the extent permitted by law, the Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are
absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same.
Nothing herein shall limit the 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 the Warrant Shares upon exercise of the Warrant as required pursuant to the terms hereof. 
 6. Charges, Taxes
and Expenses. Issuance and delivery of the Warrant Shares upon exercise of this Warrant shall be made without charge to the Holder for any issue or transfer tax, transfer agent fee or other incidental tax or expense in respect of the issuance of
the Warrant Shares, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the registration of Warrant Shares
or the Warrants in a name other than that of the Holder or an Affiliate thereof. The Holder shall be responsible for all other tax liabilities that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon
exercise hereof. 
 7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued
in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction (in such case)
and, in each case, a customary and reasonable indemnity and surety bond, if requested by the Company. 
 8. [Intentionally Omitted]. 

9. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant are subject to adjustment from time to
time as set forth in this Section 9. 

  
 - 4 - 








 (a) Stock Dividends and Splits. If the Company, at any time while this Warrant is
outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock, (ii) subdivides its outstanding shares of Common Stock into a larger
number of shares, or (iii) combines its outstanding shares of Common Stock into a smaller number of shares, then in each such case, the Exercise Price shall be multiplied by a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding immediately before such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustments made pursuant to clause (i) of this paragraph shall
become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall become effective
immediately after the effective date of such subdivision or combination. 
 (b) Pro Rata Distributions. If the Company, at any time
while this Warrant is outstanding, distributes to all holders of Common Stock for no consideration (i) evidences of its indebtedness, (ii) any security (other than a distribution of Common Stock covered by the preceding paragraph) or
(iii) rights or Warrants to subscribe for or purchase any security, or (iv) any other asset, including cash dividends (in each case, “Distributed Property”), then, upon any exercise of this Warrant that occurs after the
record date fixed for determination of stockholders entitled to receive such distribution, the Holder shall be entitled to receive, in addition to the Warrant Shares otherwise issuable upon such exercise (if applicable), the Distributed Property
that such Holder would have been entitled to receive in respect of such number of Warrant Shares had the Holder been the record holder of such Warrant Shares immediately prior to such record date without regard to any limitation on exercise
contained therein. 
 (c) Sales of Common Stock at less than the Exercise Price. From the date hereof until the end of the term
of this Warrant, if the Company sells or issues shares of Common Stock at a price, or warrants, options, convertible debt or equity securities, excluding shares of Common Stock issued in connection with a merger, acquisition or consolidation,
employee stock options, other stock awards pursuant to an employee benefit plan or arrangement, or equity securities issued in connection with standard non-convertible debt transactions, with an exercise price per share or a conversion price which
is less than the Exercise Price then in effect (such securities, the “Additional Securities”), the Exercise Price shall be adjusted immediately thereafter so that the Exercise Price shall be multiplied by a fraction: 

(i) the numerator of which shall be the number of shares of Common Stock outstanding immediately before such sale or issuance, plus the
number of shares of Common Stock which the aggregate consideration received by the Company for the total number of Additional Securities would purchase at a price per share equal to the Exercise Price; and 

(ii) the denominator of which shall be the number of shares of Common Stock outstanding immediately after such sale or issuance. 

Such adjustment shall be made successively whenever such an issuance is made. An adjustment pursuant to this Section 9(c) shall not result in any
change in the number of Common Stock issuable upon exercise of this Warrant. 

  
 - 5 - 








 (d) Fundamental Transactions. 

(i) In the case of any Fundamental Transaction, upon any exercise of this Warrant occurring simultaneously with or subsequent to the closing of
such Fundamental Transaction, 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, without regard to any limitation
in Section 13 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 13 on the exercise of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate
Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any
different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the
Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. The Company shall cause any Successor Entity in a Fundamental Transaction in which the Company is not the survivor to assume in writing all
of the obligations of the Company under this Warrant. 
 (ii) For purposes of this Section 9(d), the following definitions shall apply:

 “Fundamental Transaction” means that (A) the Company shall, directly or indirectly, in one or more related
transactions, (i) consolidate or merge with or into (whether or not the Company is the surviving corporation) another Person, or (ii) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or
assets of the Company to another Person, or (iii) another Person completes a purchase, tender or exchange offer that is accepted by the holders of more than the 50% of the outstanding shares of Common Stock (not including any shares of Common
Stock held by the Person or Persons making or party to, or associated or affiliated with the Persons making or party to, such purchase, tender or exchange offer), or (iv) consummate a stock purchase agreement or other business combination
(including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than the 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 purchase agreement or other business combination), or (v) reorganize, recapitalize or
reclassify its Common Stock (other than as a result of a subdivision or combination of shares of Common Stock covered by Section 9(a) above) or (B) any “person” or “group” (as these terms are used for purposes of
Sections 13(d) and 14(d) of the Exchange Act) is or shall become the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 50% of the aggregate ordinary voting power represented by issued and
outstanding shares of Common Stock. 

  
 - 6 - 








 “Parent Entity” of a Person means an entity that, directly or indirectly,
controls the applicable Person and whose common shares or common stock or equivalent equity security is quoted or listed on a trading market or stock exchange (a “Principal Trading Market”), or, if there is more than one such Person
or Parent Entity, the Person or Parent Entity with the largest public market capitalization as of the date of consummation of the Fundamental Transaction. 

“Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an
unincorporated organization, any other entity and a government or any department or agency thereof. 
 “Successor Entity”
means, if applicable, the Person formed by, resulting from or surviving any Fundamental Transaction or, for the purposes of Section 9(d)(ii), the Person with which such Fundamental Transaction shall have been entered into. 

(e) Number of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraph (a) of this
Section 9, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the increased or
decreased number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment. 
 (f)
Calculations. All calculations under this Section 9 shall be rounded down to the nearest whole cent or the nearest whole share, as applicable. 

(g) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section 9, the Company at its expense will, at
the written request of the Holder, promptly compute such adjustment, in good faith, in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and
adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based.
Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent. 

(h) Notice of Corporate Events. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other
distribution of cash, securities or other property in respect of its Common Stock, including, without limitation, any granting of rights or Warrants to subscribe for or purchase any capital stock of the Company, (ii) enters into any agreement
contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then, except if such notice and the contents thereof shall be
deemed to constitute material non-public information, the Company shall deliver to the Holder a notice of such transaction at least five (5) Trading Days prior to the applicable record or effective date on which a Person would need to hold
Common Stock in order to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such
notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of its 

  
 - 7 - 








 
subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. 

10. Payment of Exercise Price. The Holder may pay the Exercise Price in immediately available funds by wire transfer to an account designated by the
Company or, alternatively, in its sole discretion, satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company shall issue to the Holder the number of Warrant Shares determined as follows:

 X = Y [(A-B)/A] 
 where:

 “X” equals the number of Warrant Shares to be issued to the Holder; 

“Y” equals the total number of Warrant Shares with respect to which this Warrant is being exercised; 

“A” equals the arithmetic average of the Closing Sale Prices of the shares of Common Stock (as reported by Bloomberg Financial
Markets) for the five (5) consecutive Trading Days ending on the date immediately preceding the Exercise Date (the “Fair Market Value”); and 

“B” equals the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise. 

For purposes of this Warrant, “Closing Sale Price” means, for any security as of any date, the last trade price for such security on the
Principal Trading Market for such security, as reported by Bloomberg Financial Markets, or, if such Principal Trading Market begins to operate on an extended hours basis and does not designate the last trade price, then the last trade price of such
security prior to 4:00 P.M., New York City time, as reported by Bloomberg Financial Markets, or if the foregoing do not apply, the last trade price of such security in the over-the-counter market on the electronic bulletin board for such security as
reported by Bloomberg Financial Markets, or, if no last trade price is reported for such security by Bloomberg Financial Markets, the average of the bid prices, or the ask prices, respectively, of any market makers for such security as reported in
the “pink sheets” by Pink Sheets LLC. If the Closing Sale Price cannot be calculated for a security on a particular date on any of the foregoing bases, the Closing Sale Price of such security on such date shall be the fair market value as
determined in good faith by the Board of Directors of the Company. The Board of Directors’ determination shall be binding upon all parties absent demonstrable error. All such determinations shall be appropriately adjusted for any stock
dividend, stock split, stock combination or other similar transaction during the applicable calculation period. 
 11. Registration Rights. The
Holder of this Warrant is entitled to the benefit of certain registration rights with respect to the Warrant and the Warrant Shares issuable upon the exercise of this Warrant pursuant to the Registration Agreement, and the registration rights with
respect to the Warrants and the Warrant Shares issuable upon the exercise of this Warrant by any 

  
 - 8 - 








 
subsequent Holder may only be assigned in accordance with the terms and provisions of the Registration Agreement. 

12. Rule 144. For purposes of Rule 144 promulgated under the Securities Act, it is intended, understood and acknowledged that the Warrant Shares issued
in a “cashless exercise” transaction shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued pursuant to the
Purchase Agreement (provided that the Commission continues to take the position that such treatment is proper at the time of such exercise). 
 13.
[Intentionally Omitted]  
 [OR] 
 13.
Limitations on Exercise. Notwithstanding anything to the contrary contained herein, the number of Warrant Shares that may be acquired by the Holder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the
extent necessary to ensure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by the Holder and its Affiliates and any other Persons whose beneficial ownership of Common Stock would
be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act, does not exceed 9.99% (the “Maximum Percentage”) of the total number of then issued and outstanding shares of Common Stock (including for
such purpose the shares of Common Stock issuable upon such exercise) unless Holder gives 61 days’ notice to the Company of its intention to exceed this 9.99% limit. For purposes of the foregoing sentence, the aggregate 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 the determination of such sentence is being made, but shall exclude
shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted
portion of any other securities of the Company beneficially owned by the Holder and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or Warrants) subject to a limitation on conversion or exercise
analogous to the limitation contained herein; provided that in no event shall the aggregate number of shares beneficially owned by the Holder and its affiliates, calculated in accordance with Section 13(d) of the Exchange Act, exceed 9.99%.
Except as set forth in the preceding sentence (other than the proviso thereto), for purposes of this paragraph (including the proviso in the immediately preceding sentence), beneficial ownership shall be calculated in accordance with
Section 13(d) of the Exchange Act; it being acknowledged by the Holder that the Company is not representing to such Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and such Holder is solely responsible
for any schedules required to be filed in accordance therewith. To the extent that the limitation contained in this Section 13 applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by such
Holder) and of which a portion of this Warrant is exercisable shall be in the sole discretion of a 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 such Holder) and of which portion of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation to verify or confirm


  
 - 9 - 








 
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 13, 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
Company’s most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock
outstanding. Upon the written request of the Holder, the Company shall within one (1) Trading Day confirm in writing to such Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares Common
Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including the Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was
reported. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 13 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. 

14. No Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares
that would otherwise be issuable, the number of Warrant Shares to be issued shall be rounded down to the next whole number and the Company shall pay the Holder in cash the fair market value (based on the Closing Sale Price) for any such fractional
shares. 
 15. Notices. Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice)
shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in the Purchase Agreement prior to 5:30
P.M., New York City time, on a Trading Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number specified in the Purchase Agreement on a day that is not a
Trading Day or later than 5:30 P.M., New York City time, on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally recognized overnight courier service specifying next business day delivery, and
(iv) upon actual receipt by the Person to whom such notice is required to be given, if by hand delivery. The address and facsimile number of a Person for such notices or communications shall be as set forth in the Purchase Agreement unless
changed by such Person by three (3) Trading Days’ prior written notice to the other Persons in accordance with this Section 15. 
 16.
Warrant Agent. The Company shall serve as Warrant agent under this Warrant. Upon fifteen (15) days’ notice to the Holder, the Company may appoint a new Warrant agent. Any corporation into which the Company or any new Warrant agent
may be merged or any corporation resulting from any consolidation to which the Company or any new Warrant agent shall be a party or any corporation to which the Company or any new Warrant agent transfers substantially all of its corporate trust or
shareholders services business shall be a successor Warrant agent under this Warrant without any further act. Any such successor Warrant agent shall promptly cause notice of its succession as Warrant agent to be mailed (by first class mail, postage
prepaid) to the Holder at the Holder’s last address as shown on the Warrant Register. 

  
 - 10 - 








 17. Miscellaneous. 

(a) No Rights as a Stockholder. The Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or
receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any
of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, amalgamation, conveyance or
otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In
addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (except upon exercise of this Warrant) or as a stockholder of the Company, whether such liabilities are asserted by
the Company or by creditors of the Company. 
 (b) Authorized Shares. 

(i) 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 reasonable actions
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 in accordance herewith, be duly authorized, validly
