 2.1 Manner of Exercise. From and after the Closing Date, and until 5:00 P.M., New York time, on the Expiration Date (the “Exercise Period”), the Holder may exercise this Warrant,
on any Business Day, for all or any part of the number of shares of Warrant Stock purchasable hereunder, subject to the terms and conditions of this Warrant. 
 In order to exercise this Warrant, in whole or in part, the Holder shall deliver to the Company at its principal office or at the office or agency designated by the Company as provided herein,
(i) a written notice of Holder’s election to exercise this Warrant, which notice shall specify the number of shares of Warrant Stock to be purchased, (ii) payment of the Warrant Price as provided herein, and (iii) this Warrant.
Such notice shall be irrevocable and substantially in the form of the subscription form appearing at the end of this Warrant as Exhibit A, duly executed by the Holder or its agent or attorney. Upon receipt thereof, the Company shall, as promptly as
reasonably practicable, execute or cause to be executed and deliver or cause to be delivered to the Holder a certificate or certificates representing the aggregate number of full shares of Warrant Stock issuable upon such exercise, together with
cash in lieu of any fraction of a share, as hereinafter provided. The stock certificate or certificates so delivered shall be, to the extent possible, in such denomination or denominations as the Holder shall reasonably request in the notice and
shall be registered in the name of the Holder or if permitted pursuant to the terms of this Warrant such other name as shall be designated in the notice. This Warrant shall be deemed to have been exercised and such certificate or certificates shall
be deemed to have been issued, and the Holder or any other Person so designated to be named therein shall be deemed to have become a Holder of record of such shares for all purposes, as of the date when the notice, together with the payment of the
Warrant Price and this Warrant, is received by the Company as described above. If this Warrant shall 

  

 Page 4 of 17 








 
have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing Warrant Stock, deliver to the Holder
a new Warrant evidencing the rights of the Holder to purchase the unpurchased shares of Common Stock called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant, or at the request of the Holder,
appropriate notation may be made on this Warrant and the same returned to the Holder. 
 Payment of the
Warrant Price may be made at the option of the Holder by: (i) certified or official bank check payable to the order of the Company, or (ii) wire transfer of immediately available funds to the account of the Company. All shares of Common
Stock issuable upon the exercise of this Warrant pursuant to the terms hereof shall be validly issued and, upon payment of the Warrant Price, shall be fully paid and nonassessable and not subject to any preemptive rights. 
 2.2 Fractional Shares. The Company shall not be required to issue a fractional share of Common Stock upon exercise
of any Warrant. As to any fraction of a share which the Holder of one or more Warrants, the rights under which are exercised in the same transaction, would otherwise be entitled to purchase upon such exercise, the Company shall pay an amount in cash
equal to the Current Market Price per share of Common Stock on the date of exercise multiplied by such fraction. 
 2.3 Restrictions on Exercise Amount. Notwithstanding anything herein to the contrary, in no event shall the Holder be entitled to exercise any portion of this Warrant in excess of that portion of this Warrant upon exercise of which
the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its Affiliates (other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unexercised portion of the Warrant or
the unexercised or unconverted portion of any other security of the Holder subject to a limitation on conversion analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the exercise of the
portion of this Warrant with respect to which the determination of this proviso is being made, would result in beneficial ownership by the Holder and its Affiliates of more than 4.99% of the then outstanding shares of Common Stock. For purposes of
the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder, except as otherwise provided in
clause (1) of such proviso. The Holder may waive the limitations set forth herein by sixty-one (61) days written notice to the Corporation. 
 3. Transfer, Division and Combination. 
 3.1 Transfer. The
Warrants and the Warrant Stock shall be freely transferable, subject to compliance with this Section 3.1 and all applicable laws, including, but not limited to the Securities Act. If, at the time of the surrender of this Warrant in connection
with any transfer of this Warrant or the resale of the Warrant Stock, this Warrant or the Warrant Stock, as applicable, shall not be registered for resale under the Securities Act, the Company may require, as a condition of allowing such transfer
(i) that the Holder or 

  

 Page 5 of 17 








 
transferee of this Warrant or the Warrant Stock as the case may be, at the cost of Holder or transferee, furnish to the Company a written opinion of counsel
that is reasonably acceptable to the Company to the effect that such transfer may be made without registration under the Securities Act and any applicable state law, (ii) that the Holder or transferee execute and deliver to the Company an
investment representation letter in form and substance acceptable to the Company and substantially in the form attached as Exhibit C hereto and (iii) that the transferee be an “accredited investor” as defined in Rule 501
(a) promulgated under the Securities Act. Transfer of this Warrant and all rights hereunder, in whole or in part, in accordance with the foregoing provisions, shall be registered on the books of the Company to be maintained for such purpose,
upon surrender of this Warrant at the principal office of the Company referred to in Section 2.1 or the office or agency designated by the Company as provided herein, together with a written assignment of this Warrant substantially in the form
of Exhibit B hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute
and deliver a new Warrant or Warrants in the name of the assignee or assignees and in the denomination specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned,
and this Warrant shall promptly be cancelled. Following a transfer that complies with the requirements of this Section 3.1, the Warrant may be exercised by a new Holder for the purchase of shares of Common Stock regardless of whether the
Company issued or registered a new Warrant on the books of the Company. In connection with any transfer of this Warrant or the resale of the Warrant Stock pursuant to Rule 144 or other than pursuant to an effective registration statement, the Holder
or transferee shall compensate the Company for its reasonable expenses incurred in connection with effectuating such transfer or resale. 
 3.2 Restrictive Legends. Each certificate for Warrant Stock initially issued upon the exercise of this Warrant, and each certificate for Warrant Stock issued to any subsequent transferee of any such
certificate, unless, in each case, such Warrant Stock is eligible for resale without registration pursuant to Rule 144(k) or an effective registration statement under the Securities Act, shall bear the following legend: 
 “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED, AND MAY NOT BE
OFFERED OR SOLD IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT OR AN OPINION OF THE COMPANY’S COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.” 
 The legend set forth above shall be removed and the Company shall issue a certificate without such legend to the holder of the Shares upon which it is stamped or issue to such holder by
electronic delivery at the applicable balance account at DTC, if (i) such Shares are registered for resale under the Securities Act, (ii) such Shares are sold or transferred pursuant to Rule 144 (assuming the transferor is not an Affiliate
of the Company), (iii) such Shares are eligible for sale under Rule 144(k), or (iv) if such legend is not required under applicable requirements of the Securities Act (including controlling judicial 

  

 Page 6 of 17 








 
interpretations and pronouncements issued by the Commission). The Company shall cause its counsel to issue the legal opinion referred to in the Irrevocable
Transfer Agent Instructions to the Company’s transfer agent on the Effective Date. Any fees (with respect to the Transfer Agent, counsel to the Company or otherwise) associated with the issuance of such opinion or the removal of such legend
shall be borne by the Company. Following the Effective Date or at such earlier time as a legend is no longer required for certain Shares, the Company will no later than three (3) Trading Days following the delivery by a Purchaser to the Company
or the Transfer Agent (with notice to the Company) of a legended certificate representing such Shares (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer and an
opinion of counsel to the extent required by Section 4.1(a)), deliver or cause to be delivered to such Purchaser a certificate representing such Shares that is free from all restrictive and other legends. The Company may not make any notation
on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section. 
 The Company shall facilitate the timely preparation and delivery of certificates representing the Warrant Stock to be sold pursuant to an effective Registration Statement, which certificates shall be free, to the extent permitted by
applicable law and this Warrant, of all restrictive legends, and to enable such Warrant Stock to be in such denominations and registered in such names as the Holder may request at least five (5) business days prior to any sale of the Warrant
Stock. In connection therewith, the Company shall promptly after the effectiveness of the Registration Statement cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations,
certificates and directions required by the transfer agent, which authorize and direct the transfer agent to issue such Warrant Stock without legend upon sale by the holder of such Warrant Stock under the Registration Statement, for such time as the
Registration Statement is effective. 
 3.3 Division and Combination; Expenses; Books. This Warrant may
be divided or combined with other Warrants upon presentation hereof at the aforesaid office or agency of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder
or its agent or attorney. Subject to compliance with Section 3.1 as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
to be divided or combined in accordance with such notice. The Company shall prepare, issue and deliver at Holder’s expense the new Warrant or Warrants under this Section 3. The Company agrees to maintain, at its aforesaid office or agency,
books for the registration and the registration of transfer of the Warrants. 
 4. Adjustments. The number of shares
of Common Stock for which this Warrant is exercisable, and the price at which such shares may be purchased upon exercise of this Warrant, shall be subject to adjustment from time to time as set forth in this Section 4. 
  

 Page 7 of 17 








 4.1 Stock Dividends, Subdivisions and Combinations. If at any time
while this Warrant is outstanding the Company shall: 
 (i) declare a dividend or make a distribution on its
outstanding shares of Common Stock in shares of Common Stock; 
 (ii) subdivide its outstanding shares of
Common Stock into a larger number of shares of Common Stock; or 
 (iii) combine its outstanding shares of
Common Stock into a smaller number of shares of Common Stock, then: 
 (1) the number of shares of Common
Stock acquirable upon exercise of this Warrant immediately after the occurrence of any such event shall be adjusted to equal the number of shares of Common Stock which a record holder of the same number of shares of Common Stock that would have been
acquirable under this Warrant immediately prior to the record date for such dividend or distribution or the effective date of such subdivision or combination would own or be entitled to receive after such record date or the effective date of such
subdivision or combination, as applicable, and 
 (2) the Current Warrant Price shall be adjusted to equal:

 (A) the Current Warrant Price in effect at the time of the record date for such dividend or distribution
or of the effective date of such subdivision or combination, multiplied by the number of shares of Common Stock into which this Warrant is exercisable immediately prior to the adjustment, divided by 
 (B) the number of shares of Common Stock into which this Warrant is exercisable immediately after such adjustment.

 Any adjustment 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 clauses (ii) or (iii) of this paragraph shall become effective immediately after the effective date of
such subdivision or combination. 
 4.2 Certain Other Distributions. If at any time while this Warrant
is outstanding the Company shall cause all of the holders of its Common Stock to be entitled to receive any dividend or other distribution of: 
 (i) cash, 
 (ii) any evidences of its indebtedness, any
shares of stock of any class or any other securities or property or assets of any nature whatsoever (other than cash or additional shares of Common Stock as provided in Section 4.1 hereof), or 
  

 Page 8 of 17 








 (iii) any warrants or other rights to subscribe for or purchase any
evidences of its indebtedness, any shares of stock of any class or any other securities or property or assets of any nature whatsoever (in each case set forth in subparagraphs 4.2(i), 4.2(ii) and 4.2(iii) hereof, the “Distributed
Property”), 
 then upon any exercise of this Warrant that occurs after the record date for such dividend or other distribution, the
holder of this Warrant shall be entitled to receive, in addition to the shares of Warrant Stock, 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 as of such record date. Such distribution shall be made whenever any such exercise is made. A reclassification of the Common Stock (other than a change in par value, or from par value to no par value or from no par
value to par value) into shares of Common Stock and shares of any other class of stock shall be deemed a distribution by the Corporation to the holders of its Common Stock of such shares of such other class of stock within the meaning of this
Section 4.2 and, if the outstanding shares of Common Stock shall be changed into a larger or smaller number of shares of Common Stock as a part of such reclassification, such change shall be deemed a subdivision or combination, as the case may
be, of the outstanding shares of Common Stock within the meaning of Section 4.1. 
 4.3 Other
Provisions Applicable to Adjustments. The following provisions shall be applicable to the making of adjustments of the number of shares of Common Stock into which this Warrant is exercisable and the Current Warrant Price provided for in
Section 4: 
 (a) When Adjustments to Be Made. The adjustments required by Section 4 shall be
made whenever and as often as any specified event requiring an adjustment shall occur, except that any that would otherwise be required may be postponed (except in the case of a subdivision or combination of shares of the Common Stock, as provided
for in Section 4.1) up to, but not beyond the date of exercise if such adjustment either by itself or with other adjustments not previously made adds or subtracts less than 1% of the shares of Common Stock into which this Warrant is exercisable
immediately prior to the making of such adjustment. Any adjustment representing a change of less than such minimum amount (except as aforesaid) which is postponed shall be carried forward and made as soon as such adjustment, together with other
adjustments required by this Section 4 and not previously made, would result in a minimum adjustment or on the date of exercise. For the purpose of any adjustment, any specified event shall be deemed to have occurred at the close of business on
the date of its occurrence. 
 (b) Fractional Interests. In computing adjustments under this
Section 4, fractional interests in Common Stock shall be taken into account to the nearest 1/100th of a share. 
 (c) When Adjustment Not Required. If the Company undertakes a transaction contemplated under this Section 4 and as a result takes a record of the holders of its Common Stock for the purpose of entitling them to receive a 

  

 Page 9 of 17 








 
dividend or distribution or subscription or purchase rights or other benefits contemplated under this Section 4 and shall, thereafter and before the
distribution to stockholders thereof, legally abandon its plan to pay or deliver such dividend, distribution, subscription or purchase rights or other benefits contemplated under this Section 4, then thereafter no adjustment shall be required
by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled. 
 (d) Escrow of Stock. If after any property becomes distributable pursuant to Section 4 by reason of the taking of any record of the holders of Common Stock, but prior to the occurrence of the event for
which such record is taken, a holder of this Warrant exercises the Warrant during such time, then such holder shall continue to be entitled to receive any shares of Common Stock issuable upon exercise hereunder by reason of such adjustment and such
shares or other property shall be held in escrow for the holder of this Warrant by the Company to be issued to holder of this Warrant upon and to the extent that the event actually takes place. Notwithstanding any other provision to the contrary
herein, if the event for which such record was taken fails to occur or is rescinded, then such escrowed shares shall be canceled by the Company and escrowed property returned to the Company. 
 4.4 Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets. 
 (a) If there shall occur a Change of Control and, pursuant to the terms of such Change of Control, shares of common stock
of the successor or acquiring corporation, or any cash, shares of stock or other securities or property of any nature whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common stock of the successor
or acquiring corporation (“Other Property”), are to be received by or distributed to the holders of Common Stock of the Company, then the Holder of this Warrant shall have the right thereafter for the Balance of the Exercise Period to
receive, upon the exercise of the 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 the Other Property receivable upon or as a result of such Change of
Control by a holder of the number of shares of Common Stock into which this Warrant is exercisable immediately prior to such event. 
 (b) In case of any such Change of Control described above, the resulting, successor or acquiring entity (if not the Company) and, if an entity different from the successor or acquiring entity, the entity whose capital
stock or assets the holders of the Common Stock are entitled to receive as a result of such Change of Control, shall assume by written instrument all of the obligations of this Warrant and the Transaction Documents (as defined in the Purchase
Agreement), subject to such modifications as may be deemed appropriate (as determined by resolution of the Board of Directors of the Company) in order to 

  

 Page 10 of 17 








 
provide for adjustments of shares of the Common Stock into which this Warrant is exercisable which shall be as nearly equivalent as practicable to the
adjustments provided for in Section 4. For purposes of Section 4, common stock of the successor or acquiring corporation shall include stock of such corporation of any class which is not preferred as to dividends or assets on liquidation
over any other class of stock of such corporation and which is not subject to redemption and shall also include any evidences of indebtedness, shares of stock or other securities which are convertible into or exchangeable for any such stock, either
immediately or upon the arrival of a specified date or the happening of a specified event and any warrants or other rights to subscribe for or purchase any such stock. The foregoing provisions of this Section 4 shall similarly apply to
successive Change of Control transactions. 
 4.5 Stock Transfer Taxes. The issue of stock certificates
upon exercise of this Warrant shall be made without charge to the holder for any tax in respect of such issue. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and
delivery of shares in any name other than that of the holder of this Warrant, and the Company shall not be required to issue or deliver any such stock certificate unless and until the person or persons requesting the issue thereof shall have paid to
the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 
 5. No Rights as Stockholder. This Warrant does not entitle the Holder to any voting or other rights as a stockholder of the Company prior to exercise and payment for the Warrant Price in accordance with the terms hereof. 

6. Reservation and Authorization of Common Stock. From and after the Closing Date, the Company shall at all times reserve and
keep available for issue upon the exercise of Warrants such number of its authorized but unissued shares of Common Stock as will be sufficient to permit the exercise in full of all outstanding Warrants 
 7. Taking of Record; Stock and Warrant Transfer Books. In the case of all dividends or other distributions by the Company to the
holders of its Common Stock with respect to which any provision of Section 4 refers to the taking of a record of such holders, the Company will in each such case take such a record and will take such record as of the close of business on a
Business Day. The Company will not at any time, except upon dissolution, liquidation or winding up of the Company, close its stock transfer books or Warrant transfer books so as to result in preventing or delaying the exercise or transfer of any
Warrant. 
 8. Registration Rights. The resale of the Warrant Stock shall be registered in accordance with and subject
to the terms and conditions contained in the Purchase Agreement. The Holder acknowledges that pursuant to the Purchase Agreement, the Company has the right to request that the Holder furnish information regarding such Holder and the distribution of
the Warrant Stock as is required by law or the Commission to be disclosed in the Registration Statement (as such term is defined in the Purchase Agreement), and the Company may exclude from such registration the shares of Warrant Stock acquirable
hereunder if Holder fails to furnish 

  

 Page 11 of 17 








 
such information within a reasonable time prior to the filing of each Registration Statement, supplemented prospectus included therein and/or amended
Registration Statement. 
 9. Loss or Mutilation. Upon receipt by the Company from the Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of this Warrant and indemnity or security reasonably satisfactory to it and reimbursement to the Company of all reasonable expenses incidental thereto and in case
of mutilation upon surrender and cancellation hereof, the Company, at Holder’s cost, will execute and deliver in lieu hereof a new Warrant of like tenor to the Holder; provided, however, that in the case of mutilation, no indemnity shall be
required if this Warrant in identifiable form is surrendered to the Company for cancellation. 
 10. Office of the
Company. As long as any of the Warrants remain outstanding, the Company shall maintain an office or agency (which may be the principal executive offices of the Company) where the Warrants may be presented for exercise, registration of transfer,
division or combination as provided in this Warrant. 
 11. [Reserved] 
 12. Miscellaneous. 
 12.1 Nonwaiver. No course of dealing or any delay or failure to exercise any right or obligation hereunder on the part of the Holder or the Company shall operate as a waiver of such right or obligation, unless
the same shall be in writing signed by the Holder or the Company. 
 12.2 Notice Generally. All
notices, requests, demands or other communications provided for herein shall be in writing and shall be given in the manner and to the addresses set forth in the Purchase Agreement.

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