the Company that (i) the Purchaser has full right, power, authority and capacity to enter into this Agreement and to consummate the transactions contemplated hereby and has taken all necessary action to authorize the execution, delivery and
performance of this Agreement, (ii) the making and performance of this Agreement by the Purchaser and the consummation of the transactions herein contemplated will not violate any provision of the organizational documents of the Purchaser or

other instrument to which the Purchaser is a party, or any statute or any authorization, judgment, decree, order, rule or regulation of any court or any regulatory body, administrative agency or other governmental body applicable to the Purchaser,

of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except to the extent enforcement of the indemnification provisions, set forth in Section 7.3 of this Agreement, may be limited by federal or
state securities laws or the public policy underlying such laws, and (v) there is not in effect any order enjoining or restraining the Purchaser from entering into or engaging in any of the transactions contemplated by this Agreement.

 SECTION 7. Registration of the Shares and Warrant Shares; Compliance with the Securities Act.

  
 7.1 Registration Procedures and
Expenses. The Company shall: 
  
 (a) as soon as
practicable, but in no event later than five business days following the Closing Date, prepare and file with the Commission the Registration Statement on Form S-3 relating to the sale of the Shares and the Warrant Shares by the Purchaser and the
Other Purchasers from time to time on the Nasdaq National Market or the facilities of any national securities exchange on which the Common Stock is then traded or in privately-negotiated transactions; 
  
 (b) use its best efforts, subject to receipt of necessary information from
the Purchasers, to cause the Commission to declare the Registration Statement effective within 5 business days of receipt by the Company of confirmation that the Commission will not review the Registration Statement and within 90 days after the
Closing Date if the Registration Statement is reviewed by the Commission; 
  
 (c) use its best efforts to promptly prepare and file with the Commission such amendments and supplements to the Registration Statement and the Prospectus as may be necessary to keep the Registration Statement
effective until the earliest of (i) two years after the effective date of the Registration Statement, or (ii) such time as the Shares and the Warrant Shares become eligible for resale by non-affiliates pursuant to Rule 144(k) under the Securities
Act; 
  
 (d) furnish to the Purchaser with respect to the Shares
and Warrant Shares registered under the Registration Statement (and to each underwriter, if any, of such Shares or Warrant Shares) such number of copies of prospectuses and such other documents as the Purchaser may reasonably request, in order to
facilitate the public sale or other disposition of all or any of the Shares and Warrant Shares by the Purchaser; 
  
 (e) file documents required of the Company for normal Blue Sky clearance in states specified in writing by the Purchaser; provided,
however, that the Company shall not be required to qualify to do business or consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented; 
  
 (f) bear all expenses in connection with the procedures in paragraphs (a)
through (e) of this Section 7.1 and the registration of the Shares and the Warrant Shares pursuant to the Registration Statement, other than fees and expenses, if any, of counsel or other advisers to the Purchaser or the Other Purchasers or
underwriting discounts, brokerage fees and commissions incurred by the Purchaser or the Other Purchasers, if any; 
  
 (g) file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof to the Purchaser promptly after filing;

  
 (h) issue a press release describing the transactions
contemplated by this Agreement on the Closing Date; and 
  

 13 

 (i) until the Closing Date, make available its Chief Executive Officer, Chief Financial Officer, and
Chief Administrative Officer for questions regarding information which the Purchaser may reasonably request in order to fulfill any due diligence obligation on its part. 
  
 The Company understands that the Purchaser disclaims being an underwriter, but the Purchaser being deemed an underwriter
shall not relieve the Company of any obligations it has hereunder. A draft of the proposed form of the Registration Statement is included in the Private Placement Memorandum and a questionnaire related thereto to be completed by the Purchaser is
attached hereto as Appendix I. 
  
 7.2
Transfer of Shares and Warrant Shares After Registration. The Purchaser agrees that it will not effect any disposition of the Securities or the Warrant Shares or its right to purchase the Securities or the Warrant Shares that would constitute
a sale within the meaning of the Securities Act or any applicable state securities laws, except as contemplated in the Registration Statement referred to in Section 7.1 or as otherwise permitted by law, and that it will promptly notify the Company
of any changes in the information set forth in the Registration Statement regarding the Purchaser or its plan of distribution. 
  
 7.3 Indemnification. For the purpose of this Section 7.3: 
  
 (i) the term “Purchaser/Affiliate” shall mean any affiliate of the Purchaser, including a transferee who is an
affiliate of the Purchaser, and any person who controls the Purchaser or any affiliate of the Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and 
  
 (ii) the term “Registration Statement” shall include any
preliminary prospectus, final prospectus, exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Registration Statement referred to in Section 7.1. 
  
 (a) The Company agrees to indemnify and hold harmless each Purchaser and
each Purchaser/Affiliate against any losses, claims, damages, liabilities or expenses, joint or several, to which such Purchaser or Purchaser/Affiliate may become subject, under the Securities Act, the Exchange Act, or any other federal or state
statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the prior written consent of the Company), insofar as such losses, claims, damages, liabilities or expenses
(or actions in respect thereof as contemplated below) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, including the Prospectus, financial statements and
schedules, and all other documents filed as a part thereof, as amended at the time of effectiveness of the Registration Statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of
Rule 430A, or pursuant to Rule 434, of the Rules and Regulations, or the Prospectus, in the form first filed with the Commission pursuant to Rule 424(b) of the Regulations, or filed as part of the Registration Statement at the time of 
  

 14 

 effectiveness if no Rule 424(b) filing is required, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state in any of them a material fact required to be stated therein or necessary to make the statements in any of them, in light of the circumstances under which they were made, not misleading, or arise out of
or are based in whole or in part on any inaccuracy in the representations or warranties of the Company contained in this Agreement, or any failure of the Company to perform its obligations hereunder or under law, and will promptly reimburse each
such Purchaser and each such Purchaser/Affiliate for any legal and other expenses as such expenses are reasonably incurred by such Purchaser or such Purchaser/Affiliate in connection with investigating, defending or preparing to defend, settling,
compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable in any such case to the extent, but only to the extent, that any such loss, claim, damage,
liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein, or (ii) the failure of such Purchaser to comply with the covenants and agreements contained in Sections 5 or 7.2, or (iii) the
inaccuracy of any representation or warranty made by such Purchaser herein or (iv) any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Purchaser prior to the pertinent sale or sales by
the Purchaser. 
  
 (b) Each Purchaser will severally indemnify
and hold harmless the Company, each of its directors, each of its executive officers, including such officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act, against any losses, claims, damages, liabilities or expenses to which the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person may become subject,
under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such
Purchaser) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon (i) any failure to comply with the covenants and agreements contained in Sections 5 or
7.2 hereof, or (ii) the inaccuracy of any representation or warranty made by such Purchaser herein, or (iii) any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any Purchaser expressly for use therein, and will reimburse the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person for any legal
and other expense reasonably incurred by the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person in connection with investigating, defending, settling, compromising or paying any such
loss, claim, damage, liability, expense or action. 
  

 15 

 (c) Promptly after receipt by an indemnified party under this Section 7.3 of notice of the threat or
commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 7.3, promptly notify the indemnifying party in writing thereof; but the omission so to notify the
indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 7.3 to the extent it is not prejudiced in its ability to
defend such action as a result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to
participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if
the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded, based on an opinion of counsel reasonably satisfactory to the indemnifying party, that there
may be a conflict of interest between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on
behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 7.3 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed such
counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel,
reasonably satisfactory to such indemnifying party, representing all of the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to
represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. In no event shall any indemnifying
party be liable in respect of any amounts paid in settlement of any action unless the indemnifying party shall have approved in writing the terms of such settlement; provided that such consent shall not be unreasonably withheld. No
indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnification could
have been sought hereunder by such indemnified party from all liability on claims that are the subject matter of such proceeding. 
  
 (d) If the indemnification provided for in this Section 7.3 is required by its terms but is for any reason held to be unavailable to or otherwise
insufficient to hold harmless an indemnified party under paragraphs (a), (b) or (c) of this Section 7.3 in respect to any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying party shall contribute
to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to herein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the

  

 16 

 Purchaser from the private placement of Common Stock hereunder or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but the relative fault of the Company and the Purchaser in connection with the statements or omissions or
inaccuracies in the representations and warranties in this Agreement and/or the Registration Statement which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The respective
relative benefits received by the Company on the one hand and each Purchaser on the other shall be deemed to be in the same proportion as the amount paid by such Purchaser to the Company pursuant to this Agreement for the Securities purchased by
such Purchaser that were sold pursuant to the Registration Statement bears to the difference (the “Difference”) between the amount such Purchaser paid for the Shares that were sold pursuant to the Registration Statement and the amount
received by such Purchaser from such sale. The relative fault of the Company, on the one hand, and each Purchaser on the other shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the
omission or alleged omission to state a material fact or the inaccurate or the alleged inaccurate representation and/or warranty relates to information supplied by the Company or by such Purchaser and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject
to the limitations set forth in paragraph (c) of this Section 7.3, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in paragraph (c) of
this Section 7.3 with respect to the notice of the threat or commencement of any threat or action shall apply if a claim for contribution is to be made under this paragraph (d); provided, however, that no additional notice shall be
required with respect to any threat or action for which notice has been given under paragraph (c) for purposes of indemnification. The Company and each Purchaser agree that it would not be just and equitable if contribution pursuant to this Section
7.3 were determined solely by pro rata allocation (even if the Purchaser were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this paragraph.
Notwithstanding the provisions of this Section 7.3, no Purchaser shall be required to contribute any amount in excess of the amount by which the Difference exceeds the amount of any damages that such Purchaser has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The Purchasers’ obligations to contribute pursuant to this Section 7.3 are several and not joint. 
  
 7.4 Termination of Conditions and Obligations. The restrictions imposed by Section 5 or this Section 7 upon the transferability of
the Securities and the Warrant Shares shall cease and terminate as to any particular number of the Shares or Warrant Shares upon the passage of two years from the effective date of the Registration Statement covering such Securities or Warrant
Shares to the extent such Shares or Warrant Shares are eligible for resale pursuant to Rule 144(k) under the Securities Act or at such time as an opinion of counsel satisfactory in form and substance to the Company shall have been rendered to the
effect that such conditions are not necessary in order to comply with the Securities Act. 
  

 17 

 7.5 Information Available. So long as the Registration Statement is effective
covering the resale of Shares and Warrant Shares owned by the Purchaser and the Purchaser continues to hold the Shares and Warrant Shares, the Company will furnish to the Purchaser: 
  
 (a) to the extent not available via EDGAR, as soon as practicable after available (but in the case of the Annual Report to
the Stockholders, within 150 days after the end of each fiscal year of the Company), one copy of (i) its Annual Report to Stockholders (which Annual Report shall contain financial statements audited in accordance with generally accepted accounting
principles by a national firm of certified public accountants), (ii) if not included in substance in the Annual Report to Stockholders, upon the request of Purchaser, its Annual Report on Form 10-K, (iii) upon request of Purchaser, its quarterly
reports on Form 10-Q, and (iv) a full copy of the particular Registration Statement covering the Shares and Warrant Shares (the foregoing, in each case, excluding exhibits) and 
  
 (b) upon the reasonable request of the Purchaser, a reasonable number of copies of the Prospectuses, and any supplements
thereto, to supply to any other party requiring such Prospectuses. 
  
 SECTION 8. Broker’s Fee. The Purchaser acknowledges that the Company intends to pay to the Placement Agent a fee in respect of the sale of the Securities to the Purchaser. The Purchaser and the Company hereby agree that the
Purchaser shall not be responsible for such fee and that the Company will indemnify and hold harmless the Purchaser and each Purchaser/Affiliate against any losses, claims, damages, liabilities or expenses, joint or several, to which such Purchaser
or Purchaser/Affiliate may become subject with respect to such fee. Each of the parties hereto hereby represents that, on the basis of any actions and agreements by it, there are no other brokers or finders entitled to compensation in connection
with the sale of the Securities to the Purchaser. 
  
 SECTION 9.
Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (i) upon delivery to the party to be notified; (ii) when received by confirmed facsimile or (iii) one (1) business day after
deposit with a nationally recognized overnight carrier, specifying next business day delivery, with written verification of receipt. All communications shall be sent to the Company and the Purchaser as follows or at such other addresses as the

holder and the Company are unable to agree upon the arithmetic calculation of the Warrant Shares within two (2) Business Days of such disputed arithmetic calculation being transmitted to the holder, then the Company shall within one (1) Business Day
transmit via facsimile the disputed arithmetic calculation of the Warrant Shares to its independent, outside accountant. The Company shall cause the accountant to perform the calculations and notify the Company and the holder of the results no later
than forty-eight (48) hours, but at least one Business Day, from the time it receives the disputed calculations. Such accountant’s calculation shall be deemed conclusive absent manifest error. 
  
 (b) Unless the rights represented by this Warrant shall have expired or shall
have been fully exercised, the Company shall, as soon as practicable and in no event later than five (5) Business Days after receipt of the Exercise Delivery Documents and at its own expense, issue a new Warrant identical in all respects to this
Warrant except it shall represent rights to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant exercised, less the number of Warrant Shares with respect to which this Warrant is exercised.

  
 (c) No fractional shares of Common Stock are to be issued upon
the exercise of this Warrant, but rather the number of shares of Common Stock issued upon exercise of this Warrant shall be rounded up or down to the nearest whole number. 
  
 Section 3. Covenants as to Common Stock. The Company hereby covenants and agrees as follows: 
  
 (a) This Warrant is, and any Warrants issued in substitution for or
replacement of this Warrant upon issuance will be, duly authorized and validly issued. 
  

 -3- 

 (b) All Warrant Shares which may be issued upon the exercise of the rights represented by this Warrant
upon issuance will be validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof. 
  
 (c) During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized and reserved at
least 100% of the number of shares of Common Stock needed to provide for the exercise of the rights then represented by this Warrant and the par value of said shares will at all times be less than or equal to the applicable Exercise Price.

  
 (d) The Company shall promptly secure the listing of the
shares of Common Stock issuable upon exercise of this Warrant upon each national securities exchange or automated quotation system, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance upon exercise of
this Warrant) and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all shares of Common Stock from time to time issuable upon the exercise of this Warrant; and the Company shall so list on each national
securities exchange or automated quotation system, as the case may be, and shall maintain such listing of, any other shares of capital stock of the Company issuable upon the exercise of this Warrant if and so long as any shares of the same class
shall be listed on such national securities exchange or automated quotation system. 
  
 (e) The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities, or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of
all such action as may reasonably be requested by the holder of this Warrant in order to protect the exercise privilege of the holder of this Warrant against dilution or other impairment, consistent with the tenor and purpose of this Warrant.
Without limiting the generality of the foregoing, the Company (i) will 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, and (ii) will 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. 
  
 Section 4. Taxes. The Company shall pay any and all taxes which may be payable with respect to the issuance and
delivery of Warrant Shares upon exercise of this Warrant. 
  
 Section 5. Warrant Holder Not Deemed a Stockholder. Except as otherwise specifically provided herein, no holder, as such, of this Warrant shall be entitled to vote or receive dividends or be deemed the holder of shares of the Company
for any purpose, nor shall anything contained in this Warrant be construed to confer upon the holder hereof, as such, 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 this Warrant
of the Warrant Shares which he or she 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 such holder to purchase any securities or as a
stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. 
  

 -4- 

 Section 6. Representations of Holder. The holder of this Warrant, by the acceptance hereof,
represents that it is acquiring this Warrant and the Warrant Shares for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution of this Warrant or the Warrant Shares, except
pursuant to sales registered or exempted under the 1933 Act. The holder of this Warrant further represents, by acceptance hereof, that, as of this date, such holder is an “accredited investor” as such term is defined in Rule 501(a)(1) of
Regulation D promulgated by the Securities and Exchange Commission under the 1933 Act (an “Accredited Investor”). Upon exercise of this Warrant, the holder shall, if requested by the Company, confirm in writing, in a form
satisfactory to the Company, that the Warrant Shares so purchased are being acquired solely for the holder’s own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale and that such
holder is an Accredited Investor. If such holder cannot make such representations because they would be factually incorrect, it shall be a condition to such holder’s exercise of this Warrant that the Company receive such other representations
as the Company considers reasonably necessary to assure the Company that the issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws. The Company shall not be penalized or disadvantaged
by a holder’s inability to exercise this Warrant due to such holder’s inability to make the required representations in connection with the exercise of this Warrant. 
  
 Section 7. Ownership and Transfer. 
  
 (a) The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may
designate by notice to the holder hereof), a register for this Warrant, in which the Company shall record the name and address of the Person in whose name this Warrant has been issued, as well as the name and address of each transferee. The Company
may treat the Person in whose name any Warrant is registered on the register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms
of this Warrant. 
  
 (b) This Warrant may be offered for sale,
sold, transferred or assigned without the consent of the Company, except as may otherwise be required by the Purchase Agreement. 
  
 (c) The Company is obligated to register the Warrant Shares for resale under the 1933 Act pursuant to the Purchase Agreement and the initial holder of
this Warrant (and certain assignees thereof) is entitled to the registration rights in respect of the Warrant Shares as set forth in the Purchase Agreement. 
  
 Section 8. Adjustment of Warrant Exercise Price and Number of Shares. The Warrant Exercise Price and the number of shares of Common Stock issuable
upon exercise of this Warrant shall be adjusted from time to time as follows: 
  
 (a) Adjustment of Warrant Exercise Price upon Subdivision or Combination of Common Stock. If the Company at any time after the date of issuance of this Warrant 
  

 -5- 

 subdivides (by any stock split, 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 shares of Common Stock obtainable upon exercise of this Warrant will be proportionately
increased. If the Company at any time after the date of issuance of this Warrant 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 shares of Common Stock obtainable upon exercise of this Warrant will be proportionately decreased. Any adjustment under this Section 8(a) shall
become effective at the close of business on the date the subdivision or combination becomes effective. 
  
 (b) Adjustment of Warrant Exercise Price upon a Stock Dividend. If the Company at any time after the date of issuance of this Warrant, shall
declare a dividend or any other distribution upon the Common Stock which is payable in shares of Common Stock or securities convertible into shares of Common Stock, the Exercise Price in effect immediately prior to the declaration of such dividend
or distribution will be reduced to the quotient obtained by dividing (i) the number of shares of Common outstanding immediately prior to such declaration multiplied by the then effective Exercise Price by (ii) the total number of shares of Common
Stock outstanding immediately after such declaration. 
  
 (c)
Notices. Immediately upon any adjustment of the Exercise Price, the Company will give written notice thereof to the holder of this Warrant, setting forth in reasonable detail, and certifying, the calculation of such adjustment. 
  
 Section 9. Purchase Rights; Reorganization, Reclassification,
Consolidation, Merger or Sale. 
  
 (a) Any recapitalization,
reorganization, reclassification, consolidation, merger, sale of all or substantially all of the Company’s assets to another Person or other transaction in each case which is effected in such a way that holders of Common Stock are entitled to
receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock is referred to herein as an “Organic Change.” Prior to the consummation of any (i) sale of
all or substantially all of the Company’s assets to an acquiring Person or (ii) other Organic Change following which the Company is not a surviving entity, the Company will secure from the Person purchasing such assets or the successor
resulting from such Organic Change (in each case, the “Acquiring Entity”) a written agreement to deliver to each holder of Warrants in exchange for such Warrants, a security of the Acquiring Entity evidenced by a written instrument
substantially similar in form and substance to this Warrant and satisfactory to the holders of the Warrants. Prior to the consummation of any other Organic Change, the Company shall make appropriate provision to insure that each of the holders of
the Warrants will thereafter have the right to acquire and receive in lieu of or in addition to (as the case may be) the shares of Common Stock immediately theretofore acquirable and receivable upon the exercise of such holder’s Warrants
(without regard to any limitations on the exercise of this Warrant), such shares of stock, securities or assets that would have been issued or payable in such Organic Change with respect to or in exchange for the number of shares of Common Stock
which would have been acquirable and receivable upon the exercise of such holder’s Warrant as of the date of such Organic Change (without regard to any limitations on the exercise of this Warrant).

 Section 10. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen,
mutilated or destroyed, the Company shall promptly, on receipt of an indemnification undertaking (or, in the case of a mutilated Warrant, the Warrant), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or
destroyed. 
  
 Section 11. Notice. Any notices, consents,
waivers or other communications required or permitted to be given under the terms of this Warrant must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile
(provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one Business Day after deposit with a nationally recognized overnight delivery service, in each case properly
addressed to the party to receive the same. The addresses and facsimile numbers for such communications shall be:

 Section 12. Remedies, Other Obligations, 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 the Purchase Agreement, 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 of this Warrant right to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable
harm to the holder of this Warrant and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition
to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 
  
 Section 13. Amendment and Waiver. Except as otherwise provided herein, this Warrant may not be modified or amended
except pursuant to an instrument in writing signed by the Company and the holder of the Warrant. No provision hereunder may be waived other than in a written instrument executed by the waiving party. 
  
 Section 14. Governing Law. This Warrant shall be 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 any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. 
  
 Section 15. Construction; Headings. This Warrant shall be deemed to be
jointly drafted by the Company and the Purchaser (as defined in the Purchase Agreement) 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.
