Number of Shares of Common Stock:_____________


Date of Issuance: July 8, 2016 (“Issuance
Date”)


 


Sevcon, Inc., a corporation
organized under the laws of Delaware (the “Company”), hereby certifies that, for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, [HOLDER], the registered
holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to
purchase from the Company, at the Exercise Price (as defined below) then in effect, at any time or times on or after the Issuance
Date (the “Exercisability Date”), but not after 11:59 p.m., New York time, on the Expiration Date, (as defined
below), ______________ (_____________) fully paid and nonassessable shares of Common Stock (as defined below), subject to adjustment
as provided herein (the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this
Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof,
this “Warrant”), shall have the meanings set forth in Section 16. This Warrant is one of a series of substantially

therein.


 



    

     

    




EXERCISE OF WARRANT.


 


Mechanics of Exercise.


 


(i) Subject to the terms
and conditions hereof (including, without limitation, the limitations set forth in Section 1(f)), this Warrant may be exercised
by the Holder at any time or times on or after the Exercisability Date, in whole or in part (but not as to fractional shares),
by delivery (whether via facsimile, electronic mail or otherwise) of a written notice, in the form attached hereto as Exhibit
A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant. Within two (2) days
following the Exercise Notice, the Holder shall make payment to the Company of an amount equal to the Exercise Price in effect
on the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate
Exercise Price”) in cash by wire transfer of immediately available funds or, if the provisions of Section 1(d) are applicable,
by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section 1(d)). The
Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder unless this Warrant is being
exercised in full or for the remaining unexercised portion hereof, in which case the Holder shall deliver this Warrant to the Company
for cancellation within a reasonable time after such exercise. Execution and delivery of the Exercise Notice with respect to less
than all of the Warrant Shares 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.


 


(ii) On or before the first
(1st) Trading Day following the date on which the Company has received the applicable Exercise Notice, the Company shall
transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of the Exercise Notice, in the form attached
to the Exercise Notice, to the Holder and the Company’s transfer agent (the “Transfer Agent”). So long
as the Holder delivers the Aggregate Exercise Price (or notice of a Cashless Exercise) on or prior to the second (2nd)
Trading Day following the date on which the Exercise Notice has been delivered to the Company, then on or prior to the third (3rd)
Trading Day following the date on which the Exercise Notice has been delivered to the Company, or, if the Holder does not deliver
the Aggregate Exercise Price (or notice of a Cashless Exercise) on or prior to the second (2nd) Trading Day following
the date on which the Exercise Notice has been delivered to the Company, then on or prior to the second (2nd) Trading
Day following the date on which the Aggregate Exercise Price (or notice of a Cashless Exercise) is delivered (the “Share
Delivery Date”), the Company shall (x) provided that the Transfer Agent is participating in The Depository Trust Company
(“DTC”) Fast Automated Securities Transfer Program, and so long as the certificates therefor are not required
to bear a legend regarding restriction on transferability, upon the request of the Holder, credit such aggregate number of Warrant
Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account
with DTC through its Deposit / Withdrawal At Custodian system, or (y) if the Transfer Agent is not participating in the DTC Fast
Automated Securities Transfer Program or if the certificates are required to bear a legend regarding restriction on transferability,
issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant
to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with
respect to the issuance of Warrant Shares via DTC, if any, including without limitation for same day processing.


 



    

     

    




(iii) Upon Holder’s
delivery of the Exercise Notice and the Aggregate Exercise Price (or notice of a Cashless Exercise) to the Company, the Holder
shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this
Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the
date of delivery of the certificates evidencing such Warrant Shares, as the case may be.


 


(iv) If this Warrant is
physically delivered to the Company in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares
represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise,
then the Company shall as soon as practicable and in no event later than three (3) Trading Days after any exercise and at its own
expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right
to purchase the number of Warrant Shares for which this Warrant is exercisable immediately prior to such exercise under this Warrant,
less the number of Warrant Shares with respect to which this Warrant is exercised.


 


(v) The Company’s
obligations to issue and deliver Warrant Shares in accordance with the terms and subject to the conditions 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 (except any consent or waiver pursuant to Section 8 hereof), the recovery of any judgment against any Person
or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination; provided, however,
that the Company shall not be required to deliver Warrant Shares with respect to an exercise prior to the Holder’s delivery
of the Aggregate Exercise Price or notice of a Cashless Exercise with respect to such exercise.


 


Exercise Price.
For purposes of this Warrant, “Exercise Price” means Ten Dollars ($10.00), subject to adjustment as provided
herein.


 


Company’s
Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to issue to the Holder within
three (3) Business Days of the Exercise Date a certificate for the number of shares of Common Stock to which the Holder is entitled
and register such shares of Common Stock on the Company’s share register or to credit the Holder’s balance account
with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant,
and if on or after such Trading Day the Holder purchases, or another Person purchases on the Holder’s behalf or for the Holder’s
account (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder
of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”),
then the Company shall, within three (3) Business Days after the Holder’s written request and in the Holder’s discretion,
either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions,
if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s
obligation to deliver such certificate (and to issue such Warrant Shares) shall terminate, or (ii) promptly honor its obligation
to deliver to the Holder a certificate or certificates representing such Warrant Shares and pay cash to the Holder in an amount
equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing
Sale Price on the date of exercise.


 



    

     

    




Cashless Exercise.
 Notwithstanding anything contained herein to the contrary, if a registration statement (which may be the Registration Statement)
covering the issuance or resale of the Exercise Notice Warrant Shares is not available for the issuance or resale, as applicable,
of such Exercise Notice Warrant Shares, the Holder may, in its sole discretion, exercise this Warrant in whole or in part and,
in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate
Exercise Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according
to the following formula (a “Cashless Exercise”):


 


Net Number = (A x B) - (A x C)


B


 


For purposes of the foregoing formula:


 


A= the
total number of shares with respect to which this Warrant is then being exercised.


 


B= the
arithmetic average of the Closing Sale Prices of the shares of Common Stock for the five (5) consecutive Trading Days ending on
the date immediately preceding the date of the respective Exercise Notice.


 


C= the
Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.


 


If Warrant Shares
are issued in such a cashless exercise, the Company acknowledges and agrees that, so long as consistent with SEC staff guidance
under Section 3(a)(9) of the Securities Act of 1933, as amended, for purposes of SEC Rule 144(d), the holding period of the Warrants
being exercised may be tacked on to the holding period of the Warrant Shares, and the Company will not take any contrary position.


 


Disputes. 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 and resolve such dispute in accordance with
Section 11.


 



    

     

    




Beneficial Ownership.
Notwithstanding anything to the contrary contained herein, the Company shall not effect the exercise of any portion of this Warrant,
and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the terms and conditions of this Warrant
and any such exercise shall be null and void and treated as if never made, to the extent that after giving effect to such exercise,
the Holder together with the other Attribution Parties collectively would beneficially own in excess of 4.99% (the “Maximum
Percentage”) of the number of shares of Common Stock outstanding immediately after giving effect to such exercise. For
purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by the Holder and the other
Attribution Parties shall include the number of shares of Common Stock held by the Holder and all other Attribution Parties plus
the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence
is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining,
unexercised portion of this Warrant beneficially owned by the Holder or any of the other Attribution Parties and (B) exercise or
conversion of the unexercised or unconverted portion of any other securities of the Company (including, without limitation, any
convertible notes or convertible preferred stock or warrants, including the other Warrants) beneficially owned by the Holder or
any other Attribution Party subject to a limitation on conversion or exercise analogous to the limitation contained in this Section
1(f). For purposes of this Section 1(f), beneficial ownership shall be calculated in accordance with Section 13(d) of the 1934
Act. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock the Holder may acquire upon
the exercise of this Warrant without exceeding the Maximum Percentage, the Holder may rely on the number of outstanding shares
of Common Stock as reflected in (x) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and
Current Reports on Form 8-K or other public filing with the SEC, as the case may be, (y) a more recent public announcement by the
Company or (3) any other written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock
outstanding (the “Reported Outstanding Share Number”). If the Company receives an Exercise Notice from the Holder
at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the
Company shall (i) notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that
such Exercise Notice would otherwise cause the Holder’s beneficial ownership, as determined pursuant to this Section 1(f),
to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of Warrant Shares to be purchased pursuant
to such Exercise Notice (the number of shares by which such purchase is reduced, the “Reduction Shares”) and
(ii) as soon as reasonably practicable, the Company shall return to the Holder any exercise price paid by the Holder for the Reduction
Shares. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day
confirm orally and in writing or by electronic mail 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 and any other Attribution Party since the date as of which the
Reported Outstanding Share Number was reported. In the event that the issuance of Common Stock to the Holder upon exercise of this
Warrant results in the Holder and the other Attribution Parties being deemed to beneficially own, in the aggregate, more than the
Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the 1934 Act), the
number of shares so issued by which the Holder’s and the other Attribution Parties’ aggregate beneficial ownership
exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab
initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable after
the issuance of the Excess Shares has been deemed null and void, the Company shall return to the Holder the exercise price paid
by the Holder for the Excess Shares. Upon delivery of a written notice to the Company, the Holder may from time to time increase
or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified in such notice; provided that (i)
any such increase in the Maximum Percentage will not be effective until the sixty-first (61st) day after such notice is delivered
to the Company and (ii) any such increase or decrease will apply only to the Holder and the other Attribution Parties and not to
any other holder of Warrants that is not an Attribution Party of the Holder. For purposes of clarity, the shares of Common Stock
issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned
by the Holder for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the 1934 Act. No prior inability to
exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph
with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented
in a manner otherwise than in strict conformity with the terms of this Section 1(f) to the extent necessary to correct this paragraph
or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation contained
in this Section 1(f) or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation
contained in this paragraph may not be waived and shall apply to a successor holder of this Warrant.


 



    

     

    




Required Reserve Amount. 
So long as this Warrant remains outstanding, the Company shall at all times keep reserved for issuance under this Warrant a number
of shares of Common Stock at least equal to 100% of the maximum number of shares of Common Stock as shall be necessary to satisfy
the Company’s obligation to issue shares of Common Stock under the Warrants then outstanding (without regard to any limitations
on exercise) (the “Required Reserve Amount”); provided that at no time shall the number of shares of
Common Stock reserved pursuant to this Section 1(g) be reduced other than in connection with any exercise of Warrants or such other
event covered by Section 2(b) below. 


 


Insufficient Authorized
Shares. If at any time while this Warrant remains outstanding the Company does not have a sufficient number of authorized and
unreserved shares of Common Stock to satisfy its obligation to reserve for issuance the Required Reserve Amount (an “Authorized
Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized
shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for this Warrant then
outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence
of an Authorized Share Failure, but in no event later than seventy-five (75) days after the occurrence of such Authorized Share
Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares
of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use
its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause
its board of directors to recommend to the stockholders that they approve such proposal.


 



    

     

    




ADJUSTMENT OF EXERCISE
PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares shall be adjusted from time to time
as follows:


 


(a)                                                                                 
Voluntary Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise
Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.


 


Adjustment Upon Subdivision
or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides (by any stock split, stock
dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of
shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant
Shares will be proportionately increased. If the Company at any time on or after the Subscription Date combines (by combination,
reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares,
the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant
Shares will be proportionately decreased. Any adjustment under this Section 2(b) shall become effective at the close of business
on the date the subdivision or combination becomes effective.


 


RIGHTS UPON DISTRIBUTION
OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if, on or after the Subscription Date and on or prior
to the Expiration Date, the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire
its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any
distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets by way of a dividend,
spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”),
at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution
to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock
acquirable upon complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant,
including without limitation, the Maximum Percentage) immediately before the date of which a record is taken for such Distribution,
or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the
participation in such Distribution (provided, however, that to the extent that the Holder’s right to participate in any such
Distribution would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall
not be entitled to participate in such Distribution to such extent (and shall not be entitled to beneficial ownership of such shares
of Common Stock as a result of such Distribution (and beneficial ownership) to such extent) and the portion of such Distribution
shall be held in abeyance for the benefit of the Holder until such time or times as its right thereto would not result in the Holder
and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such Distribution
(and any Distributions declared or made on such initial Distribution or on any subsequent Distribution held similarly in abeyance)
to the same extent as if there had been no such limitation).


 



    

     

    




PURCHASE RIGHTS;
FUNDAMENTAL TRANSACTIONS.


 


(a)                                                                                 
Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time while this Warrant is
outstanding the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities
or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), the Holder
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder
could have acquired if the Holder had held the number of shares of Common Stock acquirable upon exercise of the unexercised portion
of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the
Maximum Percentage) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights,
or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issuance
or sale of such Purchase Rights (provided, however, that to the extent that the Holder’s right to participate in any such
Purchase Right would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall
not be entitled to participate in such Purchase Right to such extent (and shall not be entitled to beneficial ownership of such
Common Stock as a result of such Purchase Right (and beneficial ownership) to such extent) and such Purchase Right to such extent
shall be held in abeyance for the benefit of the Holder until such time or times as its right thereto would not result in the Holder
and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such right
(and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right to be held similarly
in abeyance) to the same extent as if there had been no such limitation).


 


(b)                                                                             
The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity (if not the Company)
assumes in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 4(b),
including agreements to 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, including, without limitation, a warrant which is exercisable
for a corresponding number of shares of capital stock 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 adjustments to the 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). Upon the consummation of each Fundamental
Transaction, the Successor Entity shall succeed to, and be substituted for the Company (so that from and after the date of the
applicable Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to
the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company
under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of
each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise
of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the shares of Common Stock
(or other securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall
continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction,
such shares of common stock (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have
been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately
prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted
in accordance with the provisions of this Warrant. Notwithstanding the foregoing and without limiting Section 1(f) hereof, the
Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 4(b) to permit the Fundamental
Transaction without the assumption of this Warrant. In addition to and not in substitution for any other rights hereunder, prior
to the consummation of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive
securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company
shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant
at any time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares
of the Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and
4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental
Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase
or subscription rights) (collectively, the “Corporate Event Consideration”) which the Holder would have been entitled
to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior to the
applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant). The provision made pursuant
to the preceding sentence shall be in a form and substance reasonably satisfactory to the Holder.


 



    

     

    




NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation or Bylaws,
or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issuance 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, and will at all times in good faith carry out all of the provisions of this Warrant and take all action as may be required
to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase
the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect,
(ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as this Warrant
is outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock,
solely for the purpose of effecting the exercise of the Warrants, the number of shares of Common Stock as shall from time to time
be necessary to effect the exercise of the Warrants then outstanding (without regard to any limitations on exercise).


 


WARRANT HOLDER NOT DEEMED
A STOCKHOLDER. Except as otherwise specifically provided herein, 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 capital stock 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,
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 (upon
exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company
or by creditors of the Company.


 



    

     

    




REISSUANCE OF WARRANTS.


 


(a)                                                                              
Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company,
whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)),
registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the
Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in
accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.


 


Lost, Stolen or Mutilated
Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to
the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall
execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right to purchase the Warrant
Shares then underlying this Warrant.


 


Exchangeable for Multiple
Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for
a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to purchase the number of Warrant
Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant
Shares as is designated by the Holder at the time of such surrender.


 


Issuance of New Warrants.
Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of
like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant
Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 7(a) or Section 7(c), the
Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants
issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall

operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to

shall submit the disputed determinations or arithmetic calculations via facsimile or electronic mail within two (2) Business Days
of receipt of the Exercise Notice or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder
and the Company are unable to agree upon such determination or calculation within three (3) Business Days of such disputed determination

binding upon all parties absent demonstrable error. The prevailing party in any dispute resolved pursuant to this Section 11 shall
be entitled to payment by the other party of the full amount of all reasonable expenses, including all costs and fees paid or incurred
in good faith, in relation to the resolution of such dispute.

BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be cumulative and in addition to all other remedies
available under this Warrant and any other Transaction Documents, at law or in equity (including a decree of specific performance
and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for any failure

TRANSFER.The
issuance of this Warrant and of the Warrant Shares have not been registered with the SEC in reliance upon an exemption from registration
under the Securities Act of 1933, as amended, and, accordingly, such securities may not be transferred unless (i) pursuant to an
effective registration statement under the Securities Act of 1933, as amended, (ii) pursuant to Rule 144, or (iii) the Company
has received an opinion of counsel reasonably satisfactory to it that such transfer may lawfully be made without registration under
the Securities Act of 1933, as amended.


 


SEVERABILITY; CONSTRUCTION;
HEADINGS. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a
court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended
to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision
shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express,
without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity
or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations
of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will
endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s),
the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). This Warrant shall
be deemed to be jointly drafted by the Company and all the Buyers and shall not be construed against any Person as the drafter
hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation
of, this Warrant.

Warrant
To Purchase Common Stock


 


Warrant No.: _____________


Number of Shares of Common Stock:_____________


Date of Issuance: July 8, 2016 (“Issuance
Date”)


 


Sevcon, Inc., a corporation
organized under the laws of Delaware (the “Company”), hereby certifies that, for good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, [HOLDER], the registered
holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set forth below, to
purchase from the Company, at the Exercise Price (as defined below) then in effect, at any time or times on or after the Issuance
Date (the “Exercisability Date”), but not after 11:59 p.m., New York time, on the Expiration Date, (as defined
below), ______________ (_____________) fully paid and nonassessable shares of Common Stock (as defined below), subject to adjustment
as provided herein (the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this
Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof,
this “Warrant”), shall have the meanings set forth in Section 16. This Warrant is one of a series of substantially

1.                 
EXERCISE OF WARRANT.


 


(c)                                                                                 
Mechanics of Exercise.


 


(i) Subject to the terms
and conditions hereof, this Warrant may be exercised by the Holder at any time or times on or after the Exercisability Date, in
whole or in part (but not as to fractional shares), by delivery (whether via facsimile, electronic mail or otherwise) of a written
notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election
to exercise this Warrant. Within two (2) days following the Exercise Notice, the Holder shall make payment to the Company of an
amount equal to the Exercise Price in effect on the date of such exercise multiplied by the number of Warrant Shares as to which
this Warrant is being exercised (the “Aggregate Exercise Price”) in cash by wire transfer of immediately available
funds or, if the provisions of Section 1(d) are applicable, by notifying the Company that this Warrant is being exercised pursuant
to a Cashless Exercise (as defined in Section 1(d)). The Holder shall not be required to deliver the original Warrant in order
to effect an exercise hereunder unless this Warrant is being exercised in full or for the remaining unexercised portion hereof,
in which case the Holder shall deliver this Warrant to the Company for cancellation within a reasonable time after such exercise.
Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares 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.


 


(ii) On or before the first
(1st) Trading Day following the date on which the Company has received the applicable Exercise Notice, the Company shall
transmit by facsimile or electronic mail an acknowledgment of confirmation of receipt of the Exercise Notice, in the form attached
to the Exercise Notice, to the Holder and the Company’s transfer agent (the “Transfer Agent”). So long
as the Holder delivers the Aggregate Exercise Price (or notice of a Cashless Exercise) on or prior to the second (2nd)
Trading Day following the date on which the Exercise Notice has been delivered to the Company, then on or prior to the third (3rd)
Trading Day following the date on which the Exercise Notice has been delivered to the Company, or, if the Holder does not deliver
the Aggregate Exercise Price (or notice of a Cashless Exercise) on or prior to the second (2nd) Trading Day following
the date on which the Exercise Notice has been delivered to the Company, then on or prior to the second (2nd) Trading
Day following the date on which the Aggregate Exercise Price (or notice of a Cashless Exercise) is delivered (the “Share
Delivery Date”), the Company shall (x) provided that the Transfer Agent is participating in The Depository Trust Company
(“DTC”) Fast Automated Securities Transfer Program, and so long as the certificates therefor are not required
to bear a legend regarding restriction on transferability, upon the request of the Holder, credit such aggregate number of Warrant
Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account
with DTC through its Deposit / Withdrawal At Custodian system, or (y) if the Transfer Agent is not participating in the DTC Fast
Automated Securities Transfer Program or if the certificates are required to bear a legend regarding restriction on transferability,
issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant
to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with
respect to the issuance of Warrant Shares via DTC, if any, including without limitation for same day processing.


 



    

     

    




(iii) Upon Holder’s
delivery of the Exercise Notice and the Aggregate Exercise Price (or notice of a Cashless Exercise) to the Company, the Holder
shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this
Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the
date of delivery of the certificates evidencing such Warrant Shares, as the case may be.


 


(iv) If this Warrant is
physically delivered to the Company in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares
represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise,
then the Company shall as soon as practicable and in no event later than three (3) Trading Days after any exercise and at its own
expense, issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right
to purchase the number of Warrant Shares for which this Warrant is exercisable immediately prior to such exercise under this Warrant,
less the number of Warrant Shares with respect to which this Warrant is exercised.


 


(v) The Company’s
obligations to issue and deliver Warrant Shares in accordance with the terms and subject to the conditions 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 (except any consent or waiver pursuant to Section 8 hereof), the recovery of any judgment against any Person
or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination; provided, however,
that the Company shall not be required to deliver Warrant Shares with respect to an exercise prior to the Holder’s delivery
of the Aggregate Exercise Price or notice of a Cashless Exercise with respect to such exercise.


 


(d)                                                                                
Exercise Price. For purposes of this Warrant, “Exercise Price” means Ten Dollars ($10.00), subject
to adjustment as provided herein.


 


(e)                                                                                 
Company’s Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to
issue to the Holder within three (3) Business Days of the Exercise Date a certificate for the number of shares of Common Stock
to which the Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit the
Holder’s balance account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s
exercise of this Warrant, and if on or after such Trading Day the Holder purchases, or another Person purchases on the Holder’s
behalf or for the Holder’s account (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction
of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company
(a “Buy-In”), then the Company shall, within three (3) Business Days after the Holder’s written request
and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”),
at which point the Company’s obligation to deliver such certificate (and to issue such Warrant Shares) shall terminate, or
(ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Warrant Shares and
pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares
of Common Stock, times (B) the Closing Sale Price on the date of exercise.


 



    

     

    




(f)                                                                                 
Cashless Exercise.  Notwithstanding anything contained herein to the contrary, if a registration statement
(which may be the Registration Statement) covering the issuance or resale of the Exercise Notice Warrant Shares is not available
for the issuance or resale, as applicable, of such Exercise Notice Warrant Shares, the Holder may, in its sole discretion, exercise
this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon
such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number”
of shares of Common Stock determined according to the following formula (a “Cashless Exercise”):


 


Net Number = (A x B) - (A x C)


B


 


For purposes of the foregoing formula:


 


A= the
total number of shares with respect to which this Warrant is then being exercised.


 


B= the
arithmetic average of the Closing Sale Prices of the shares of Common Stock for the five (5) consecutive Trading Days ending on
the date immediately preceding the date of the respective Exercise Notice.


 


C= the
Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.


 


If Warrant Shares
are issued in such a cashless exercise, the Company acknowledges and agrees that, so long as consistent with SEC staff guidance
under Section 3(a)(9) of the Securities Act of 1933, as amended, for purposes of SEC Rule 144(d), the holding period of the Warrants
being exercised may be tacked on to the holding period of the Warrant Shares, and the Company will not take any contrary position.


 


(g)              
Disputes. 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 and resolve
such dispute in accordance with Section 11.


 



    

     

    




(h)                                                                                
Required Reserve Amount.  So long as this Warrant remains outstanding, the Company shall at all times keep reserved
for issuance under this Warrant a number of shares of Common Stock at least equal to 100% of the maximum number of shares of Common
Stock as shall be necessary to satisfy the Company’s obligation to issue shares of Common Stock under the Warrants then outstanding
(without regard to any limitations on exercise) (the “Required Reserve Amount”); provided that at no
time shall the number of shares of Common Stock reserved pursuant to this Section 1(f) be reduced other than in connection with
any exercise of Warrants or such other event covered by Section 2(b) below. 


 


(i)                                                                                  
Insufficient Authorized Shares. If at any time while this Warrant remains outstanding the Company does not have a
sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance the Required
Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary
to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required
Reserve Amount for this Warrant then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable
after the date of the occurrence of an Authorized Share Failure, but in no event later than seventy-five (75) days after the occurrence
of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number
of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy
statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common
Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal.


 


2.                 
ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares
shall be adjusted from time to time as follows:


 


(a)                                                                                 
Voluntary Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise
Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.


 


(b)                                                                                
Adjustment Upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date
subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately
reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription
Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock
into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased
and the number of Warrant Shares will be proportionately decreased. Any adjustment under this Section 2(b) shall become effective
at the close of business on the date the subdivision or combination becomes effective.


 



    

     

    




3.                 
RIGHTS UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if, on or after the
Subscription Date and on or prior to the Expiration Date, the Company shall declare or make any dividend or other distribution
of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise
(including, without limitation, any distribution of cash, stock or other securities, property, options, evidence of indebtedness
or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar
transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the
Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein
if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to
any limitations or restrictions on exercise of this Warrant) immediately before the date of which a record is taken for such Distribution,
or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the
participation in such Distribution.


 


4.                 
PURCHASE RIGHTS; FUNDAMENTAL
TRANSACTIONS.


 


(c)                                                                                 
Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time while this Warrant is
outstanding the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities
or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), the Holder
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder
could have acquired if the Holder had held the number of shares of Common Stock acquirable upon exercise of the unexercised portion
of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant) immediately before the date on
which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of
which the record holders of Common Stock are to be determined for the grant, issuance or sale of such Purchase Rights.


 



    

     

    




(d)                                                                                
The Company shall not enter into or be party to a Fundamental Transaction unless the Successor Entity (if not the Company)
assumes in writing all of the obligations of the Company under this Warrant in accordance with the provisions of this Section 4(b),
including agreements to 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, including, without limitation, a warrant which is exercisable
for a corresponding number of shares of capital stock 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 adjustments to the 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). Upon the consummation of each Fundamental
Transaction, the Successor Entity shall succeed to, and be substituted for the Company (so that from and after the date of the
applicable Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to
the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company
under this Warrant with the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of
each Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon exercise
of this Warrant at any time after the consummation of the applicable Fundamental Transaction, in lieu of the shares of Common Stock
(or other securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall
continue to be receivable thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction,
such shares of common stock (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have
been entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately
prior to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted
in accordance with the provisions of this Warrant. Notwithstanding the foregoing, the Holder may elect, at its sole option, by
delivery of written notice to the Company to waive this Section 4(b) to permit the Fundamental Transaction without the assumption
of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation of each Fundamental
Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect
to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to
insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation
of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of the Common Stock (or other
securities, cash, assets or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue
to be receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental Transaction, such shares of stock,
securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) (collectively,
the “Corporate Event Consideration”) which the Holder would have been entitled to receive upon the happening of the
applicable Fundamental Transaction had this Warrant been exercised immediately prior to the applicable Fundamental Transaction
(without regard to any limitations on the exercise of this Warrant). The provision made pursuant to the preceding sentence shall
be in a form and substance reasonably satisfactory to the Holder.


 


5.                 
NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate
of Incorporation or Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution,
issuance 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, and will at all times in good faith carry out all of the provisions of this Warrant and take all action
as may be required to protect the rights of the Holder. Without limiting the generality of the foregoing, the Company (i) shall
not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price
then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long
as this Warrant is outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares
of Common Stock, solely for the purpose of effecting the exercise of the Warrants, the number of shares of Common Stock as shall
from time to time be necessary to effect the exercise of the Warrants then outstanding (without regard to any limitations on exercise).


 



    

     

    




6.                 
WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, 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 capital stock 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, 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 (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such
liabilities are asserted by the Company or by creditors of the Company.


 


7.                 
REISSUANCE OF WARRANTS.


 


(e)                                                                              
Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company,
whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)),
registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the
Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in
accordance with Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred.


 


(f)                                                                                 
Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification
undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this
Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 7(d)) representing the right
to purchase the Warrant Shares then underlying this Warrant.


 


(g)                                                                                
Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the
principal office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate
the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right
to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender.


 



    

     

    




(h)                                                                                
Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant,
such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant,
the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to
Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock
underlying the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying
this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance
Date, and (iv) shall have the same rights and conditions as this Warrant.

GOVERNING LAW; JURISDICTION;
JURY TRIAL. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning
the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State
of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York

or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction
to collect on the Company’s obligations to the Holder, to realize on any collateral or any other security for such obligations,
or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY

as applicable, the Company shall submit the disputed determinations or arithmetic calculations via facsimile or electronic mail
within two (2) Business Days of receipt of the Exercise Notice or other event giving rise to such dispute, as the case may be,
to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation within three (3) Business
Days of such disputed determination or calculation being submitted to the Holder, then the Company shall, within two (2) Business
Days, submit via facsimile or electronic mail (a) the disputed determination of the Exercise Price, fair market value of the Common
Stock, Weighted Average Price or Corporate Event Consideration, as applicable, to an independent, reputable investment bank selected
by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s
independent, outside accountant. The Company shall cause the investment bank or the accountant, as the case may be, to perform
the determinations or calculations and notify the Company and the Holder of the results no later than ten (10) Business Days from
the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination
or calculation, as the case may be, shall be binding upon all parties absent demonstrable error. The prevailing party in any dispute
resolved pursuant to this Section 11 shall be entitled to payment by the other party of the full amount of all reasonable expenses,
including all costs and fees paid or incurred in good faith, in relation to the resolution of such dispute.


 



    

     

    




12.

and in addition to all other remedies available under this Warrant and any other Transaction Documents, at law or in equity (including
a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue
actual damages for any failure by the Company to comply with the terms of this Warrant.


 


13.             
TRANSFER.The issuance of this Warrant and of the Warrant Shares have not been registered with the SEC in reliance
upon an exemption from registration under the Securities Act of 1933, as amended, and, accordingly, such securities may not be
transferred unless (i) pursuant to an effective registration statement under the Securities Act of 1933, as amended, (ii) pursuant
to Rule 144, or (iii) the Company has received an opinion of counsel reasonably satisfactory to it that such transfer may lawfully
be made without registration under the Securities Act of 1933, as amended.


 


14.             
SEVERABILITY; CONSTRUCTION;
HEADINGS. If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by
a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed
amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such
provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues
to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited
nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations
or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the
parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s)
with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable
provision(s). This Warrant shall be deemed to be jointly drafted by the Company and all the Buyers and shall not be construed
against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part
of, or affect the interpretation of, this Warrant.


 


15.             
DISCLOSURE. Upon receipt or delivery by the Company of any notice in accordance with the terms of this Warrant, unless
the Company has in good faith determined that the matters relating to such notice do not constitute material, nonpublic information
relating to the Company or its subsidiaries, the Company shall contemporaneously with any such receipt or delivery publicly disclose
such material, nonpublic information on a Current Report on Form 8-K or otherwise. In the event that the Company believes that
a notice contains material, nonpublic information relating to the Company or its subsidiaries, the Company so shall indicate to
such Holder contemporaneously with delivery of such notice, and in the absence of any such indication, the Holder shall be allowed
to presume that all matters relating to such notice do not constitute material, nonpublic information relating to the Company or
its subsidiaries.
