 2. Exercise of Warrant. 

(a) Manner of Exercise. 
 (i) Cash Exercise. This Warrant may be exercised, in whole or in part, at any time or from time to time, during the period commencing as of 9:30:01 a.m., New York time, on the Initial Exercise Date
and ending as of 5:30 p.m., New York time, on the Expiration Date (the “Exercise Period”), for                      fully paid and
non-assessable shares of Common Stock (the “Warrant Shares”), for an exercise price per share equal to the Exercise Price, by delivery to the Company at its headquarters, or at such other place as is designated in writing by the
Company, of: 
 (1) a duly executed Notice of Exercise, substantially in the form of Attachment I attached hereto and
incorporated by reference herein; 
 (2) this Warrant; and 

(3) subject to Section 2(a)(ii) below, payment of an amount in cash equal to the product of the Exercise Price multiplied by
the number of Warrant Shares being purchased upon such exercise, with such payment being in the form of a wire transfer of immediately available U.S. funds to an account designated in writing by the Company. 

The date on which the Company receives the Notice of Exercise, this Warrant, and the Exercise Price payable with respect to the Warrant
Shares being purchased shall be deemed to be the date of exercise (the “Date of Exercise”). 
 (ii) Cashless
Exercise. Notwithstanding the provisions of Section 2(a)(i)(3) above (requiring payment by wire transfer), the Company agrees that, unless otherwise prohibited by applicable law, the Holder shall have the right to exercise this
Warrant in full or in part on a cashless basis, computed using the following formula: 
  

			
	X = Y (A - B)
	        A

 Where: 
 X = The number of Warrant Shares to be issued to the Holder pursuant to this cashless exercise; 
 Y = The number of Warrant Shares in respect of which the net issue election is made; 
 A = The Fair Market Value (as defined below) of one Warrant Share at the time the cashless exercise election is made; and 
 B = The Exercise Price then in effect at the time of such exercise. 
 The term
“Fair Market Value” shall mean, on any given day: (A) if the class of Warrant Shares is exchange-traded, the average of the closing sales prices per share of the class of Warrant Shares for the ten (10) consecutive trading days
ending on the day that is two (2) trading days prior to the applicable 

  
 - 2 -

 
date of determination of Fair Market Value; or (B) if the class of Warrant Shares is not listed or admitted to trading on any securities exchange but is regularly traded in any
over-the-counter market, then the average of the bid and ask prices per share of the class of Warrant Shares for the ten (10) consecutive trading days ending on the day that is two (2) trading days prior to the applicable date of
determination of Fair Market Value; or (C) if the class of Warrant Shares is not traded as described in clauses (A) or (B), then the per share fair market value of the class of Warrant Shares as determined in good faith by the
Company’s Board of Directors. 
 (b) Delivery of Certificates. Certificates for Warrant Shares purchased hereunder
shall be transmitted by the transfer agent of the Company to the Holder by crediting the account of the Holder’s prime broker with the Depository Trust Company (“DTC”) through its Deposit Withdrawal Agent Commission system if
the Company is a participant in such system and such Warrant Shares are eligible for delivery in such a manner, and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise within three Business Days from the
delivery to the Company of the Notice of Exercise, surrender of this Warrant and payment of the aggregate Exercise Price as set forth above (the “Delivery Period”). This Warrant shall be deemed to have been exercised on the date on
which this Warrant is surrendered and payment of the Exercise Price is received by the Company. The Warrant Shares shall be deemed to have been issued, and 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 on which all of the criteria described in the immediately preceding sentence have occurred, irrespective of the date of delivery of such certificate or certificates, except that, if
the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock
transfer books are open. If fewer than all of the Warrant Shares purchasable under the Warrant are purchased, the Company will, upon such partial exercise, execute and deliver to the Holder a new Warrant (dated as of the Issue Date), in the same
form and tenor as this Warrant, evidencing that portion of the Warrant not exercised. 
 (c) Delivery of Electronic
Shares. In lieu of delivering physical certificates representing the Warrant Shares issuable upon exercise (provided that the transfer agent is participating in the DTC Fast Automated Securities Transfer program and provided further that the
Holder provides the transfer agent with information required in order to issue such Warrant Shares to the Holder electronically), upon the request of the Holder as set forth in the Notice of Exercise, but only if the Warrant Shares may be issued
without restrictive legends, the Company shall cause its transfer agent to electronically transmit, within the Delivery Period, the Warrant Shares issuable upon exercise to the Holder by crediting Holder’s account with DTC through its Deposit
Withdrawal Agent Commission system. Any delivery not effected by electronic transmission shall be effected by delivery of physical certificates. 
 (d) No Fractional Shares. If a fractional share of Warrant Shares would, but for the provisions of this Section 2(d), be issuable upon exercise of the rights represented by this
Warrant, the Company shall (i) round a half share or greater to be delivered to Holder up to the next whole share and (ii) round a less-than-half share to be delivered to Holder down to the nearest whole share. 

(e) Buy-In. Notwithstanding anything else to the contrary contained herein, in addition to any other rights available to the
Holder, if the Company fails to cause its transfer agent to transmit to the Holder a certificate or certificates representing the applicable Warrant Shares purchased upon exercise hereof or credit the Holder’s balance account with DTC, as
applicable, on or before the end of the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company hereunder), and if after such date the Holder purchases shares of Common Stock to
deliver in satisfaction of a sale by the Holder of Warrant Shares that the Holder anticipated receiving from the Company upon exercise of this Warrant (a “Buy-In”), then the Company shall, within three

  
 - 3 -

 
Business Days after the Holder’s request, (1) pay cash to the Holder the amount by which (x) the Holder’s total purchase price (including commissions, if any) for the shares
of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue, by (B) the price at which
the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored, or deliver to
the Holder the number of Warrant Shares that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. The Holder shall provide the Company written notice indicating the amounts payable to the
Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in
equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing the Securities as required pursuant to the terms hereof.

 (f) No Charge to Holder Upon Issuance. The issuance of Warrant Shares upon exercise of this Warrant shall be made
without charge to Holder for any issuance tax in respect thereof or other cost incurred by the Company in connection with such exercise and the related issuance of Warrant Shares (other than any transfer taxes resulting from the issuance of Warrant
Shares to any person other than Holder). 
 (g) Reservation of Shares. During the Exercise Period, the Company shall
reserve and keep available out of its authorized but unissued Common Stock such number of Warrant Shares issuable upon the full exercise of this Warrant. All Warrant Shares which are so issuable shall, when issued and upon the payment of the
applicable Exercise Price, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges and not subject to the pre-emptive rights of any holder of Common Stock or any other class or series of stock of the
Company. During the Exercise Period, the Company shall not take any action which would cause the number of authorized but unissued Common Stock to be less than the number of such shares required to be reserved hereunder for issuance upon exercise of
this Warrant. 
 (h) Limitations on Exercises. 
 (i) Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by the Holder hereof to the extent (but only to the extent) that the Holder or any of its
affiliates would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the Common Stock. To the extent the above limitation applies, the determination of whether this Warrant shall be exercisable (vis-à-vis other
convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of which such securities shall be exercisable (as among all such securities owned by the Holder) shall, subject to such Maximum Percentage
limitation, be determined on the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be). 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. For the purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation, with
respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the Exchange Act. The limitations contained in this paragraph shall apply to a successor Holder of this Warrant. 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 to the Holder the number of shares of Common Stock then outstanding, including by virtue of any prior conversion
or exercise of convertible or exercisable securities into Common Stock. The provisions of this Section 2(h)(i) may be waived by such Holder, at the election of such Holder, upon not less than 61 days’ prior

  
 - 4 -

 
notice to the Company, and the provisions of this Section 2(h)(i) shall continue to apply until such 61st day (or such later date, as determined by such Holder, as may be specified in
such notice of waiver). At 12:00 a.m., New York Time, on the 62nd day following the provision of the notice referred to in the preceding sentence, the exercise limitation set forth above shall expire. 

(ii) Notwithstanding anything else set forth herein, in no event shall this Warrant be exercisable by the Holder to the extent that the
Holder or any of its affiliates and any other Person whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), would beneficially own in excess of 19.99% of the number of shares of the Company’s Common Stock outstanding at the time of such issuance unless any issuances in excess of the foregoing limitation are approved by the
Company’s common stockholders. 
 3. Adjustments in Certain Events. The number, class, and price of Warrant Shares for which this
Warrant may be exercised are subject to adjustment from time to time upon the happening of certain events as follows: 
 (a)
Subdivisions, Combinations and Other Issuances. If the outstanding shares of the Company’s Common Stock are divided into a greater number of shares, by forward stock split or otherwise, or a dividend in stock is paid on the Common Stock,
then the number of shares of Warrant Shares for which the Warrant is then exercisable will be proportionately increased and the Exercise Price will be proportionately reduced. Conversely, if the outstanding shares of Common Stock are combined into a
smaller number of shares of Common Stock, by reverse stock split or otherwise, then the number of Warrant Shares for which the Warrant is then exercisable will be proportionately reduced and the Exercise Price will be proportionately increased. The
increases and reductions provided for in this Section 3(a) will be made with the intent and, as nearly as practicable, the effect that neither the percentage of the total equity of the Company obtainable on exercise of the Warrants nor
the price payable for such percentage upon such exercise will be affected by any event described in this Section 3(a). 
 (b) Merger, Consolidation, Reclassification, Reorganization, Etc. In case of any change in the Common Stock through merger, consolidation, reclassification, reorganization, partial or complete
liquidation, purchase of all or substantially all the assets of the Company, or other change in the capital structure of the Company, then, as a condition of such change, lawful and adequate provision will be made so that the Holder will have the
right thereafter to receive upon the exercise of the Warrant the kind and amount of shares of stock or other securities or property to which he would have been entitled if, immediately prior to such event, he had held the number of Warrant Shares
obtainable upon the exercise of the Warrant. In any such case, appropriate adjustment will be made in the application of the provisions set forth herein with respect to the rights and interest thereafter of the Holder, to the end that the provisions
set forth herein will thereafter be applicable, as nearly as reasonably may be, in relation to any shares of stock or other property thereafter deliverable upon the exercise of the Warrant. The Company will not permit any change in its capital
structure to occur unless the issuer of the shares of stock or other securities to be received by the Holder, if not the Company, agrees to be bound by and comply with the provisions of this Warrant. 

(c) Notice of Record Date, Etc. In the event the Company shall propose to take any action of the types requiring an adjustment
pursuant to this Section 3 or a dissolution, liquidation or winding up of the Company shall be proposed, the Company shall give notice to Holder as provided in Section 6 below, which notice shall specify the record date, if
any, with respect to any such action and the date on which such action is to take place. Such notice shall also set forth such facts with respect thereto as shall be reasonably necessary to indicate the effect of such action (to the extent such
effect may be known at the 

  
 - 5 -

 
date of such notice) on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable or purchasable upon the occurrence of such action or
deliverable upon the exercise of the Warrant. In the case of any action which will require the fixing of a record date, unless otherwise provided in this Warrant, such notice shall be given at least twenty (20) days prior to the date so fixed,
and in case of all other action, such notice shall be given at least thirty (30) days prior to the taking of such proposed action. 
 (d) If securities of the Company or securities of any subsidiary of the Company are distributed pro rata to holders of Common Stock, such number of securities will be distributed to the Holder or its
assignee upon exercise of its rights hereunder as such Holder or assignee would have been entitled to if this Warrant had been exercised prior to the record date for such distribution. The provisions with respect to adjustment of the Common Stock
provided in this Section 3 will also apply to the securities to which the Holder or its assignee is entitled under this Section 3(d). 
 4. No Rights as a Stockholder. Nothing contained in this Agreement shall be construed as conferring upon the Holder any rights whatsoever as a stockholder of the Company, either at law or in
equity, including without limitation, or Holders the right to vote or to consent or to receive notice as a stockholder in respect of any meetings of stockholders for the election of directors the right to receive dividends or any other matter.

 5. Restrictions on Transfer; Legends. 
 (a) Registration or Exemption Required. Assuming the accuracy of the representations and warranties of the Holder contained in herein, this Warrant has been issued in a transaction exempt from the
registration requirements of the Securities Act by virtue of Section 4(2) of the Securities Act and Regulation D promulgated thereunder and exempt from state registration or qualification under applicable state laws. The Holder acknowledges
that he has been advised by the Company that this Warrant and the Warrant Shares issuable upon exercise thereof have not been registered under the Securities Act. Neither this Warrant nor the Warrant Shares may be pledged, transferred, sold or
assigned except pursuant to an effective registration statement or an exemption to the registration requirements of the Securities Act and applicable state laws. If, at the time of the surrender of this Warrant in connection with any transfer of
this Warrant, the transfer of this Warrant shall not be registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing
such transfer (i) that the Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable
transactions) to the effect that such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the holder or transferee execute and deliver to the Company an investment
letter in form and substance acceptable to the Company and (iii) that the transferee be an “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act or a “qualified institutional buyer” as defined
in Rule 144A(a) under the Securities Act. 
 (b) Representations of Holder. The Holder represents and warrants that he
has acquired this Warrant and will acquire the Warrant Shares for his own account for investment and not with a view to the sale or distribution thereof or the granting of any participation therein, and that he has no present intention of
distributing or selling to others any of such interest or granting any participation therein. The Holder acknowledges that the Warrant and Warrant Shares must be held indefinitely unless a subsequent disposition thereof is registered under the
Securities Act or registered or qualified under any applicable state securities or “blue-sky” laws or is exempt from registration and/or qualification. The Holder has no need for liquidity in its investment in the Company, and is able to
bear the economic risk of such investment for an indefinite period and to afford a complete loss thereof. The Holder is an “accredited investor” as such term is defined in Rule 501 (the provisions of which are known to the Holder)
promulgated under the Act. 

  
 - 6 -

 (c) Restrictive Legend. The Holder understands that until such time as the Warrant
Shares have been registered under the Securities Act, or otherwise may be sold pursuant to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a
particular date that can then be immediately sold, this Warrant and the Warrant Shares, as applicable, shall bear a restrictive legend in substantially the form set forth on the cover page of this Warrant (and a stop-transfer order may be placed
against transfer of the certificates for such securities). 
 (d) Disposition of Warrant or Warrant Shares. With
respect to any offer, sale or other disposition of this Warrant or any Warrant Shares prior to registration of such Warrant Shares, the Holder agrees to give written notice to the Company prior thereto, describing briefly the manner thereof,
together with evidence, reasonably satisfactory to the Company (which shall include such representation of the transferee regarding investment intent as the Company may request, to the effect that such offer, sale or other disposition may be
effected without registration or qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or such Warrant Shares and indicating whether or not under the Securities Act certificates for
this Warrant or Warrant Shares to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law. Upon receiving such written notice and reasonably
satisfactory evidence, the Company, as promptly as practicable but no later than seven (7) days after receipt of the written notice, shall notify the Holder that the Holder may sell or otherwise dispose of this Warrant or Warrant Shares, all in
accordance with the terms of the notice delivered to the Company. If the Company determines that the evidence is not reasonably satisfactory to the Company, the Company shall so notify the Holder promptly with details thereof after such
determination has been made. Notwithstanding the foregoing, any Warrant Shares may be offered, sold or otherwise disposed of in accordance with Rule 144 under the Act and in compliance with the applicable statutory resale restrictions
imposed by state securities laws, provided that the Company shall have been furnished with such information as the Company may reasonably request to provide a reasonable assurance that the provisions of Rule 144 and the applicable resale
restrictions imposed by state securities laws have been satisfied. Each certificate representing this Warrant or the Warrant Shares thus transferred shall bear a legend as to the applicable restrictions on transferability in order to ensure
compliance with such laws, unless pursuant to an opinion of counsel for the Holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop transfer instructions to its transfer agent in connection
with such restrictions. 
 (e) Removal of Restrictive Legends. The certificates evidencing the Warrant Shares shall not
contain any legend restricting the transfer thereof: (A) while a registration statement covering the sale or resale of the Warrant Shares is effective under the Securities Act and such legend removal is permitted under applicable securities
laws (including compliance with the prospectus delivery requirements of the Securities Act), or (B) following any sale of such Warrant Shares pursuant to Rule 144, or (C) if such Warrant Shares are eligible for sale under Rule 144(b)(1),
or (D) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) and the Company shall have received an opinion of counsel to
the Holder in form reasonably acceptable to the Company to such effect (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel to issue a legal opinion to its transfer agent if required by the transfer
agent to effect the issuance of the Warrant Shares, as applicable, without a restrictive legend or removal of the legend hereunder. The Company agrees that at such time as the Unrestricted Conditions are met, it will, no later than three
(3) Trading Days following the delivery by the Holder to the Company or the transfer agent of a certificate representing Warrant Shares, issued with a restrictive legend, deliver or cause to be delivered to such Holder a certificate (or
electronic transfer) representing such Warrant Shares that is free from all restrictive and other legends. 

  
 - 7 -

 6. Registration Rights. The Holder shall be entitled to all of the rights and subject to all of
the obligations regarding registration of the shares of Common Stock issuable upon the exercise of this Warrant as described in the Purchase Agreement. 
 7. Notices; Adjustments. 
 (i) All notices required or permitted hereunder
shall be in writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified; (ii) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not,
then on the next business day; (iii) two (2) Business Days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one (1) Business Day after deposit with a nationally recognized
overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company or to Holder, as applicable, at the respective addresses set forth on the signature page to the Purchase Agreement
or at such other address(es) as they may designate, respectively, by ten (10) days advance written notice to the other party hereto. 
 (ii) Upon the occurrence of any adjustments pursuant to Section 3 hereof, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter,
compute such adjustment in accordance with the terms hereof and furnish to Holder a certificate setting forth such adjustment and showing in detail the facts upon which such adjustment is based. 

8. Non-Circumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its certificate of incorporation, bylaws
or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other 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 the provisions of this Warrant and take all action as may be reasonably required to protect the rights of the Holder. 
 9. Governing Law. This Warrant shall be governed by and construed in accordance with the laws of the State of New York, without regard to conflict of law principles, and notwithstanding the fact
that one or more counterparts hereof may be executed outside of the state, or one or more of the obligations of the parties hereunder are to be performed outside of the state. 
 10. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant, and, in
the case of loss, theft, or destruction, of indemnity reasonably satisfactory to it, and, if mutilated, upon surrender and cancellation of this Warrant, the Company will execute and deliver a new Warrant, having terms and conditions identical to
this Warrant, in lieu hereof. 
 11. Modification and Waiver of Class A Warrants. Any term of this Warrant may be amended, waived,
discharged or terminated (either generally or in a particular instance and either retroactively or prospectively) with the written consent of the Company and the holders of the Class A Warrants representing at least 51% of the number of shares
of Common Stock then subject to outstanding Class A Warrants. Notwithstanding the foregoing, (a) this Warrant may be amended and the observance of any term hereunder may be waived without the written consent of the Holder only in a manner
which applies to all Class A Warrants in the same fashion and (b) the number of Warrant Shares subject to this Warrant and the Exercise Price of this Warrant may not be amended, and the right to exercise this Class A Warrant

  
 - 8 -

 
may not be waived, without the written consent of the Holder. The Company shall give prompt written notice to the Holder of any amendment hereof or waiver hereunder that was effected without the
Holder’s written consent. No waivers of any term, condition or provision of this Class A Warrant, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or
provision. 
 12. Successors. This Warrant shall be binding and inure to the benefit of the parties and their respective successors and
assigns hereunder; provided that this Warrant may be assigned by Holder only in compliance with the conditions specified in and in accordance with all of the terms of this Warrant. This Warrant does not create and shall not be construed as creating
any rights enforceable by any other person or corporation. 
 13. Headings. The headings used in this Warrant are used for convenience
only and are not to be considered in construing or interpreting this Warrant. 
 14. Saturdays, Sundays, Holidays. If the last or
appointed day for the taking of any action or the expiration of any right required or granted herein shall be a Saturday or a Sunday or shall be a legal holiday in the State of New York, then such action may be taken or such right may be
exercised on the next succeeding day not a legal holiday. 
 15. Severability. If any provision of this Warrant shall be held to be
invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions of this Warrant. 
 16. Execution and
Counterparts. This Warrant may be executed in any number of counterparts, each of which when so executed and delivered shall be deemed an original, and such counterparts together shall constitute only one instrument. Any one of such counterparts
shall be sufficient for the purpose of proving the existence and terms of this Warrant, and no party shall be required to produce an original or all of such counterparts in making such proof. 
 17. Acceptance. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.

the contrary, subject to receipt of the approval of the Company’s stockholders, the Company shall not issue, and no Purchaser shall be permitted to purchase (whether hereunder or upon exercise of the Warrants) any shares of Common Stock if and
to the extent that the purchase and issuance of such shares of Common Stock would cause the Company to exceed the aggregate number of shares of Common Stock which the Company may issue or be deemed to have issued without breaching the Company’s
obligations under the applicable rules and regulations of the Nasdaq Stock Market (including, 

  
 4 

 
without limitation, Nasdaq Listing Rules 5635(b)) and such other Trading Market on which the Company’s shares of Common Stock are then listed or quoted for trading (the “Exchange
Cap”). In the absence of such stockholder approval, in no event shall a Purchaser be permitted to acquire shares of Common Stock in an amount greater than the product of the Exchange Cap. 

2.4 Stockholder Approval. Solely in the event that it is required in order to permit the full exercise of the Warrants issued
pursuant to this Agreement into shares of Common Stock in accordance with applicable Nasdaq Listing Rules (the “Stockholder Approval”), the Company shall, following its determination that such Stockholder Approval is required
pursuant to the applicable rules of the Nasdaq Stock Market, at its next regularly scheduled annual meeting of stockholders and any subsequent special or annual meeting to the extent required, call a meeting of its stockholders for the purpose of
obtaining the Stockholder Approval, with the recommendation of the Board of Directors that such proposal be approved, and the Company shall solicit proxies from its stockholders in connection therewith in the same manner as all other management
proposals in such proxy statement and all management-appointed proxyholders shall vote their proxies in favor of such proposal. If the Company does not obtain Stockholder Approval at the first meeting, the Company shall call a meeting no less
frequently than every 180 days thereafter to seek Stockholder Approval until the earlier of the date that Stockholder Approval is obtained or the Warrants are no longer outstanding. Each Purchaser further agrees that it shall not be entitled to vote
the shares of Common Stock of the Company issuable to it pursuant to the terms of this Agreement, including pursuant to the exercise of any Warrants, at any meeting of the Company’s stockholders convened to vote on a proposal to enable the
Company to issue the shares of Common Stock underlying the Warrants in excess of 19.99% of the issued and outstanding Common Stock of the Company. 
 ARTICLE III 
 REPRESENTATIONS AND WARRANTIES 

3.1 Representations and Warranties of the Company. The Company hereby represents and warrants to the Purchasers as follows:

standing under the laws of the State of Delaware and has the requisite legal authority to own and use its properties and assets and to carry on its business as currently conducted. The Company is not in violation of any of the provisions of its
certificate of incorporation, bylaws or other organizational or charter documents. The Company is duly qualified to do business and is in good standing as a foreign corporation or other entity in each jurisdiction in which the nature of the
business conducted or property owned by the Company makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, would not, individually or in the aggregate, have, or reasonably be expected
to result in, a Material Adverse Effect (defined below). For purposes of this Agreement, “Material Adverse Effect” means (i) a material adverse effect on the results of operations, assets, business or financial condition
of the Company and its Subsidiaries, taken as a whole on a consolidated basis, or (ii) material and adverse impairment of the Company’s ability to perform its obligations under this Agreement, provided that none of the following alone
shall be deemed, in and of itself, to constitute a Material Adverse Effect: (A) a change in the market price or trading volume of the shares of Common Stock of the Company or (B) changes in general economic conditions or changes
affecting the industry in which the Company operates generally (as opposed to Company-specific changes) so long as such changes do not have a disproportionate effect on the Company and its Subsidiaries, taken as a whole. 

(b) Authorization; Enforcement. The Company has the requisite corporate authority to enter into this Agreement and to carry
out its obligations hereunder. The execution and delivery of this 

  
 5

Agreement and the Security Agreement has been duly executed and delivered by the Company and constitutes, and the certificates representing the Notes and Warrants, when executed and delivered in accordance with the terms hereof, will constitute, a
valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or
affecting the enforcement of creditors’ rights generally; (ii) the effect of rules of law governing the availability of specific performance and other equitable remedies; and (iii) insofar as indemnification and contribution
provisions may be limited by applicable law. 
 (c) Required Approvals; No Conflicts. The Company is not required to
obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person or entity in connection with the execution,
delivery and performance by the Company of this Agreement or the issuance, sale or delivery of the Securities other than the Required Approvals and if required, the Stockholder Approval contemplated by Section 2.4 of this Agreement.
Subject to the Required Approvals and if required, the Stockholder Approval contemplated by Section 2.4 of this Agreement, the execution and delivery by the Company of this Agreement and the certificates representing the Notes and the
Warrants, and the performance by the Company of its obligations hereunder and thereunder, do not and will not (i) conflict with or violate any provision of the Company’s certificate of incorporation, bylaws or other organizational or
charter documents, (ii) conflict with, or constitute a default under (or an event that, with notice or lapse of time or both, would become a default under), or give to others any rights of termination, amendment, acceleration or cancellation
under (with or without notice, lapse of time or both), any agreement, credit facility, debt or other instrument evidencing a debt of the Company or other understanding to which the Company is a party, or by which any of its properties or assets is
bound, except to the extent that such conflict or default or termination, amendment, acceleration or cancellation right would not reasonably be expected to have a Material Adverse Effect, or (iii) result in a violation of any law, rule,
regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company is subject, or by which any of its properties or assets is bound, except to the extent that such violation would not
reasonably be expected to have a Material Adverse Effect.

respects the information required by the Securities Act to be shown with respect to such plans, options and rights. 
 (e)

(f) Litigation. Except as described in the Company’s reports filed with the SEC pursuant to the Exchange Act (the
“SEC Reports”), there is no pending or, to the best knowledge of the Company, threatened action, suit, proceeding or investigation before any court, governmental agency or body, or arbitrator having jurisdiction over the Company, or
any of its Affiliates that would affect the execution by the Company or the performance by the Company of its obligations under this Agreement, and all other agreements entered into by the Company relating hereto. Except as disclosed in the SEC
Reports, there is no pending or, to the best knowledge of the Company, threatened action, suit, proceeding or investigation before any court, governmental agency or body, or arbitrator having jurisdiction over the Company, or any of its Affiliates
which litigation if adversely determined could have a Material Adverse Effect. 
 (g) Intellectual Property. Except as
disclosed in the SEC Reports, each of the Company and its subsidiaries owns or has the valid right to use all Intellectual Property (as defined below) necessary for the conduct of the businesses of the Company and its subsidiaries in the manner
described in the SEC Reports as now conducted or proposed to be conducted. Except as disclosed in the SEC Reports: (i) to the knowledge of the Company, no third party has infringed, misappropriated, diluted or otherwise violated in any material
respect any Intellectual Property rights of the Company or any of its subsidiaries, and no claims for any of the foregoing have been brought against any third party by the Company or any of its subsidiaries; (ii) the Intellectual Property owned
by the Company or its subsidiaries and, to the knowledge of the Company, the Intellectual Property licensed to the Company or its subsidiaries have not been adjudged invalid or unenforceable, in whole or in part, and there is no pending or, to the
knowledge of the Company, threatened action, suit, proceeding, investigation or claim challenging the validity, enforceability, scope, issuance/registration, use or ownership of any such Intellectual Property, and the Company is unaware of any facts
which would form a reasonable basis for any such claim; (iii) there is no pending or, to the knowledge of the Company, threatened action, suit, proceeding or claim by others that the Company or any of its subsidiaries infringes,
misappropriates, dilutes or otherwise violates any Intellectual Property of others; and (iv) each of the Company and its subsidiaries has taken commercially reasonable steps, consistent with industry standards, to maintain and protect all
Intellectual Property that is material to the conduct of its business. The term “Intellectual Property” as used herein means all patents, patent applications, trademarks, trademark applications, service marks, trade names, trade
dress, domain names, copyrights, licenses, inventions, trade secrets, technology, software, systems, know-how and other intellectual property and proprietary rights.

in each case free and clear of all Liens, except such as (i) are described in the SEC Reports; (ii) do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the

 7 

 
Any real property and buildings held under lease by the Company and its subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as do not interfere with
the use made and proposed to be made of such property and buildings by the Company and its subsidiaries. 
 (i) Permits.
The Company and its subsidiaries possess all licenses, certificates, clearances, authorizations or permits issued by the appropriate governmental or regulatory agencies or authorities (collectively, “Permits”) that are necessary to
enable them to own, lease and operate their respective properties and to carry on their respective businesses as presently conducted, except where the failure to possess such licenses, certificates, authorization or permits would not reasonably be
expected to have a Material Adverse Effect. The Company has not received notice of any revocation or modification of any such Permits and has no reason to believe that any such license, certificate, permit or authorization will not be renewed in the
ordinary course. The Company has not received any Form 483 notice of adverse finding from the U.S. Food and Drug Administration (“FDA”), warning letter, untitled letter or other correspondence or notice from FDA or any other governmental
or regulatory authority alleging or asserting noncompliance with any applicable laws or any Permits. The Company has filed, obtained, maintained or submitted all material reports, documents, forms, notices, applications, records, claims, submissions
and supplements or amendments as required by any applicable laws or Permits and that all such reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments were complete and correct on the date filed in
all material respects (or were corrected or supplemented by a subsequent submission). 
 (j) Financial Statements. The
financial statements of the Company, together with the related schedules and the notes thereto, included or incorporated by reference in the SEC Reports comply in all material respects with applicable accounting requirements and the applicable
requirements of the Securities Act and Exchange Act as in effect at the time of filing. Such financial statements have been prepared in accordance with generally accepted accounting principles applied on a consistent basis during the periods
involved (“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto, and fairly present in all material respects the financial position of the Company as of and for the dates thereof and the
results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments. EisnerAmper LLP, who has audited certain financial statements of the Company, are
independent registered public accountants as required by the Securities Act and Exchange Act and have been appointed by the Company’s audit committee (if so empowered by the Board of Directors) comprised only of independent directors, or by the
Board of Directors, as the case may be. 
 (k) Material Liabilities and Indebtedness. Since the date of the latest
audited financial statements included in the SEC Reports, except as disclosed in the SEC Reports: (i) there has been no event, occurrence or development that, individually or in the aggregate, has had or could result in a Material Adverse
Effect, (ii) the Company has not incurred any liabilities (contingent or otherwise) other than (A) trade payables and accrued expenses incurred in the ordinary course of business consistent with past practice and (B) liabilities not
required to be reflected in the Company’s financial statements pursuant to GAAP or required to be disclosed in filings made with the Commission, (iii) the Company has not altered its method of accounting or the identity of its auditors,
and (iv) other than with respect to the Company’s outstanding shares of Series B Convertible Preferred Stock and Series C Convertible Preferred Stock, the Company has not declared or made any dividend or distribution of cash or other
property to its shareholders or purchased, redeemed or made any agreements to purchase or redeem any shares of its capital stock. Except for the issuance of the Securities contemplated by this Agreement or as set forth in the SEC Reports or Proxy
Statement, no event, liability or development has occurred or exists with respect to the Company or its subsidiaries or their respective business, properties, operations or financial condition, that would be required to be disclosed by the Company
under applicable securities laws at the time this representation is made or deemed made that has not been publicly disclosed at least one Trading Day prior to the date that this representation is made. 

  
 8 

 (l) Nature of Company’s Obligation. The Company further acknowledges that its
obligations under the Transaction Agreements, including, without limitation, its obligation to issue the Warrant Shares, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the
effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company. 

(m) No Defaults. Except as disclosed in the Company’s SEC Reports, the Company and its Subsidiaries are not, nor have they
received notice that they would be with the passage of time, giving of notice, or both, in breach or violation of any of the terms and provisions of, or in default under (a) their charters and bylaws, (b) any statute, rule, regulation or
order of any governmental agency or body or any court, domestic or foreign, having jurisdiction over them, or any of their material assets or properties, or (c) any material agreement or instrument to which they are a party or by which they are
bound or to which any of their assets or properties are subject, except, in the case of clauses (b) and (c) only, for such conflicts, breaches or violations as have not and could not reasonably be expected to result in, individually or in
the aggregate, a Material Adverse Effect. 
 (n) Insurance. The Company, on behalf of itself and its subsidiaries,
carries, or is covered by, insurance from insurers of recognized financial responsibility in such amounts and covering such risks as is customary for companies engaged in similar businesses in similar industries. All policies of insurance of the
Company and its subsidiaries are in full force and effect; each of the Company and its subsidiaries is in compliance with the terms of such policies in all material respects; and none of the Company or its subsidiaries has received notice from any
insurer or agent of such insurer that capital improvements or other expenditures are required or necessary to be made in order to continue such insurance; there are no claims by the Company or any of its subsidiaries under any such policy or
instrument as to which any insurance company is denying liability or defending under a reservation of rights clause; and none of the Company or its subsidiaries has any reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that could not reasonably be expected to have a Material Adverse Effect. 

(o) Taxes. The Company has filed all federal, state, local and foreign income and franchise tax returns required to be filed
through the date hereof, subject to permitted extensions, and has paid all taxes due thereon, and no tax deficiency has been determined adversely to the Company, nor does the Company have any knowledge of any tax deficiencies that could, in the
aggregate, reasonably be expected to have a Material Adverse Effect. There is no pending dispute with any taxing authority relating to the Company’s payment of taxes in any material amount except which the Company is contesting in good faith
and the Company has no knowledge of any proposed liability for any tax to be imposed upon the properties or assets of the Company for which there is not an adequate reserve reflected in the Company’s financial statements included or
incorporated by reference in the SEC Reports. 
 (p) Trading Market. Except as disclosed in the SEC Reports, the Company
has not, in the twelve (12) months preceding the date hereof, received notice from the Nasdaq Stock Market (the “Principal Market”) to the effect that the Company is not in compliance with the listing or maintenance
requirements of the Principal Market. Except as described in the SEC Reports, the Company has no reason to believe that it will not in the foreseeable future continue to be in compliance or regain compliance in a timely manner, as the case may be,
with all such listing and maintenance requirements. The issuance and sale of the Securities hereunder does not contravene, in a manner which is expected to 

  
 9 

 
have a Material Adverse Effect, the rules and regulations of the Principal Market and no stockholder approval is required for the Company to fulfill its obligations under the Transaction
Agreements, other than as described in this Agreement. The Common Stock has been registered pursuant to Section 12(b) of the Exchange Act and is currently listed on the Principal Market. 

(q) SEC Reports. The Company has filed all SEC Reports required to be filed by it under the Exchange Act for the two years
preceding the date hereof on a timely basis or has received a valid extension of such time of filing and has filed any such SEC Reports prior to the expiration of any such extension. As of their respective dates, the SEC Reports filed for the two
years preceding the date hereof have complied in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder, and none of such SEC Reports, when filed, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(r) Sarbanes-Oxley Compliance. The Company is in compliance in all material respects with all provisions of the Sarbanes-Oxley Act
of 2002, as amended, applicable to it, and the applicable rules and regulations promulgated thereunder by all government and regulatory authorities and agencies. The Company maintains a system of internal accounting controls sufficient to provide
reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles in the United States and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect thereto. The Company has established and maintains and evaluates “disclosure controls and procedures” (as
such term is defined in Rule 13a-15 and Rule 15d-15 under the Exchange Act) and “internal control over financial reporting” (as such term is defined in Rule 13a-15 and Rule 15d-15 under the Exchange Act). The Company’s certifying
officers have evaluated the effectiveness of the Company’s disclosure controls and procedures and the Company presented in its Form 10-Q for the fiscal quarter ended December 31, 2011, the conclusions of the Company’s certifying
officers about the effectiveness of such disclosure controls and procedures. 
 The Purchaser acknowledges and agrees that the
Company does not make and has not made any representations or warranties with respect to the transactions contemplated hereby other than those representations and warranties specifically set forth in this Agreement.

and warrants with respect to only itself, as of the Closing Date, that:

 (b) No Conflicts. The execution, delivery and performance by the Purchaser of this
Agreement and each of the Transaction Agreements to which it is a party, and the consummation by the Purchaser of the transactions contemplated by this Agreement and each such Transaction Agreement, do not and will not (i) conflict with or

limited circumstances. Such Purchaser acknowledges that all certificates representing any of the Notes, the Warrants, and shares of Common Stock issuable upon exercise of the Warrants will bear a restrictive legend in a form as set forth below

registered thereunder, (B) such Purchaser shall have delivered to the Company an opinion of counsel, in a generally acceptable form, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred
pursuant to an exemption from such registration, or (C) such Purchaser provides the Company with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the Securities
Act (or a successor rule thereto) (collectively, “Rule 144”); (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any
resale of the Securities under circumstances in which the seller (or the Person (through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under
the Securities Act or the rules and regulations of the Commission thereunder; and (iii) neither the Company nor any other Person is under any obligation to register the Securities under the Securities Act or any state securities laws or to
comply with the terms and conditions of any exemption thereunder. 

  
 11

(i) Such Purchaser understands that the Securities are “restricted securities” and that the certificates or other instruments
representing the Notes and Warrants shall bear any applicable legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of
such certificates):

REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE
STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT, OR APPLICABLE STATE
SECURITIES LAWS OR PURSUANT TO AN AVAILABLE EXEMPTION THEREFROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF
COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. 
 (ii) In the
event that the Warrants are exercised for shares of Common Stock, such Warrant Shares shall bear any applicable legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a
stop-transfer order may be placed against transfer of such stock certificates): 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF
(A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT, OR (B) AN OPINION OF COUNSEL, IN A GENERALLY ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT (II) UNLESS SOLD OR TRANSFERRED TO A
“QUALIFIED INSTITUTIONAL BUYER” WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT OR (III) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. 
 (iii) The Company may at any time place a stop transfer order on its transfer books against the shares of Common Stock underlying the Warrants. Such stop order will be removed, and further transfer of
such shares of Common Stock will be permitted, upon an effective registration of the respective shares of Common Stock, or the receipt by the Company of an opinion of counsel satisfactory to the Company that such further transfer may be effected
pursuant to an applicable exemption from registration. 
 (f) Reliance on Representations. Such Purchaser understands
that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and
such Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein and in the applicable schedules 

  
 12 

 
and exhibits in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the Securities. The Purchaser undertakes to immediately notify the Company
of any change in any statement or other information relating to the Purchaser set forth in such applicable schedules and exhibits which takes place prior to the Closing time. No Person has made any written or oral representations to the Purchaser
that (i) any Person will resell or repurchase the Notes, the Warrants or the shares of Common Stock underlying the Warrants, (ii) that any Person will refund all or any part of the Purchase Price, or (iii) as to the future price or
value of the shares of Common Stock of the Company. 
 (g) Schedules. Each Purchaser acknowledges that this Agreement and
Schedule A attached hereto require the Purchaser to provide certain personal information to the Company. Such information is being collected by the Company for the purposes of completing the transactions contemplated by this Agreement, which
includes, without limitation, determining the Purchaser’s eligibility to purchase the Securities under the securities laws applicable in the United States and other applicable securities laws, preparing and registering certificates representing
the Notes and completing filings required by any stock exchange or securities regulatory authority. The Purchaser’s personal information may be disclosed by the Company to: (a) stock exchanges or securities regulatory authorities, and
(b) any of the other parties involved in the Offering, including legal counsel and may be included in record books in connection with the Offering. By executing this Agreement, the Purchaser is deemed to be consenting to the foregoing
collection, use and disclosure of the Purchaser’s personal information; provided, that in the event of a disclosure pursuant to clause (a) of the preceding sentence, the Company shall (to the extent it is legally permitted), use
commercially reasonable efforts to give such Purchaser advance notice of any required disclosure. The Purchaser also consents to the filing of copies or originals of any of the Purchaser’s documents as may be required to be filed with any stock
exchange or securities regulatory authority in connection with the transactions contemplated hereby.
 (h) No Public Sale or
Distribution. Each Purchaser will be acquiring the Notes, the Warrants and the shares of the Common Stock issuable upon exercise of the Warrants, in the ordinary course of business for his, her or its account and not for the benefit of any
other Person and not with a view towards, or for resale in connection with, the public sale or distribution thereof, and the Purchaser covenants that it will not resell the Notes the Warrants, or shares of Common Stock except pursuant to sales
registered under the Securities Act or under an exemption from such registration and in compliance with applicable U.S. federal and state securities laws, and such Purchaser does not have a present arrangement to effect any distribution of Notes,
the Warrants and the shares of the Common Stock issuable upon exercise of such Warrants to or through any Person or entity. 

(i) Investor Status. On the date such Purchaser was offered the Notes and on the date hereof and such Purchaser is and will
be either an “accredited investor” as defined in Rule 501(a) promulgated under Regulation D of the Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act. The
Purchaser has properly completed, executed and delivered to the Company the applicable “accredited investor” certificate set forth in the Schedules hereto and the information contained therein is true and correct. Such Purchaser is not
required to be registered as a broker-dealer under Section 15 of the Exchange Act. 
 (j) Experience of
Purchaser. There are risks associated with the purchase of and investment in the Notes, the Warrants, and shares of Common Stock of the Company, and the Purchaser, either alone or together with his, her or its representatives, has such
knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of entering into this Agreement and making his, her or its Purchase Price and the merits and risks of the prospective
investment in the Notes, the Warrants, and shares of Common Stock of the Company, and such Purchaser has so evaluated such merits and risks. Such Purchaser understands that he, she or it must bear the economic risk of an investment in the
Notes, the Warrants, and shares of Common Stock of the Company, if any, indefinitely and is able to bear such risk and to afford a complete loss of such investment. 

  
 13 

 (k) Access to Information. Such Purchaser acknowledges that he, she or it has
reviewed the SEC Reports and has been afforded (i) the opportunity to ask such questions as he, she or it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of this Agreement
and the merits and risks of the prospective investment in the Notes and Warrants, (ii) access to information about the Company and its Subsidiaries and their respective financial condition, results of operations, business, properties,
management and prospects sufficient to enable him, her or it to evaluate the terms and conditions of this Agreement and the merits and risks of the prospective investment in the Securities and (iii) the opportunity to obtain such additional
information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed decision. The Purchaser is not purchasing the Notes based on knowledge of material information concerning the Company
that has not been generally disclosed. Such Purchaser and its advisors, if any, in acquiring the Securities, have relied solely on their independent investigation of the Company and have been afforded the opportunity to ask questions of the Company.
Neither such inquiries nor any other due diligence investigations conducted by such Purchaser or its advisors, if any, or its representatives shall modify, amend or affect such Purchaser’s right to rely on the Company’s representations and
warranties contained herein. Such Purchaser understands that its investment in the Securities involves a high degree of risk. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed
investment decision with respect to its acquisition of the Securities. 
 (l) No Governmental Review. Each Purchaser
understands that no United States federal or state agency, or any other government or governmental agency has reviewed or passed on or made, or will pass on or make, any recommendation or endorsement of the Notes, the Warrants, or shares of Common
Stock of the Company or the fairness or suitability of the prospective investment in the Notes, the Warrants, or shares of Common Stock of the Company. 
 (m) Aggregate Investment. Each Purchaser understands that his, her or its subscription for the Securities forms part of a larger offering of Securities by the Company as described herein. Each
Purchaser understands that there is no minimum aggregate subscription required to close the Offering.
 (n) Securities and
Other Transactions. Other than consummating the transactions contemplated hereunder, the Purchaser has not, nor has any Person acting on behalf of or pursuant to any understanding with the Purchaser, directly or indirectly executed any
purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that the Purchaser first became aware of the proposed transactions contemplated hereunder and ending immediately prior to the
execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of the Purchaser’s assets and the portfolio managers have no
direct knowledge of the investment decisions made by the portfolio managers managing other portions of the Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio
manager that made the investment decision to purchase the Units covered by this Agreement. Other than to other Persons party to this Agreement and its Affiliates and their respective investment advisors, agents, counsel and other advisors, the
Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Such Purchaser has no present intent to effect a “change of control” of
the Company as such term is understood under the rules promulgated pursuant to Section 13(d) of the Exchange Act. 

  
 14 

 (o) No Legal, Tax or Investment Advice. Each Purchaser understands that nothing
in this Agreement or any other materials presented by or on behalf of the Company to him, her or it in connection with this Agreement and the transactions contemplated herein, including the prospective investment in the Notes, the Warrants, and
shares of Common Stock, constitutes legal, tax or investment advice. Each Purchaser has consulted such legal, tax and investment advisors as he, she or it, in his, her or its sole discretion, has deemed necessary or appropriate in the
circumstances. The Purchaser is not relying on the Company or its counsel in this regard. 
 The Company acknowledges and
agrees that the Purchaser does not make or has not made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Section 3.2. 

ARTICLE IV 

REGISTRATION RIGHTS 
 4.1 Piggyback Registration Rights. Each Purchaser and the Company agree that the Purchasers shall be entitled to the registration rights with respect to the Securities as set forth in this
Section 4.1 
 (a) Definition of Registrable Securities. As used in this Section 4.1, the term
“Registrable Security” means each of the shares of Common Stock which may be issued upon the exercise of the Warrants; provided, however, that with respect to any particular Registrable Security, such security shall cease to be a
Registrable Security when, as of the date of determination; (A) it has been and remains effectively registered under the Securities Act and disposed of pursuant thereto; (B) in the opinion of counsel to the Company, registration under the
Securities Act is no longer required for subsequent public distribution of such security without volume limitations pursuant to Rule 144 promulgated under the Securities Act, or otherwise; or (C) it has ceased to be outstanding. The term
“Registrable Securities” means any and all of the securities falling within the foregoing definition of “Registrable Security.” In the event of any merger, reorganization, consolidation, recapitalization or other
change in corporate structure affecting the Common Stock, such adjustment shall be made in the definition of “Registrable Security” as is appropriate to prevent any dilution or increase of the rights granted pursuant to this clause
(a) as determined in good faith by the Board of Directors. 
 (b) Piggyback Registration Rights. As used herein, a
“Registration Statement” shall mean any registration statement filed by the Company with the Commission under the Securities Act at any time or from time to time while any Registrable Securities remain outstanding; provided,
however, that a Registration Statement for the purposes hereof shall not include: (A) any registration statement (or amendment thereto) filed by the Company which has not been declared effective on or before the date hereof; (B) any
registration statement on Form S-3 (or any successor form) filed by the Company for the purpose of effecting offers and sales of securities on a continuous or delayed basis pursuant to Rule 415(a)(ix) or (x) under the Securities Act; (C) a
registration relating to employee benefit plans (whether effected on Form S-8 or its successor); or (D) a registration effected on Form S-4 (or its successor). If at any time or from time to time while any Registrable Securities
remain outstanding, the Company shall determine to register or shall be required to register any of its Common Stock, whether or not for its own account, the Company shall: 
 (i) provide to each Purchaser written notice thereof at least seven days prior to the filing of the Registration Statement by the Company in connection with such registration; 

(ii) include in such registration, and in any underwriting involved therein, all those Registrable Securities specified in a written
request by each Purchaser received by the Company 

  
 15 

 
within five days after the Company mails the written notice referred to above. The Company may withdraw the registration at any time. If a registration covered by this Section 4.1 is an
underwritten registration on behalf of the Company, and the underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in such offering
without adversely affecting the marketability of the offering, the Company shall include in such registration: (1) first, the securities the Company proposes to sell, (2) second, the Registrable Securities and other securities requested to
be included in such registration, pro rata among the selling Purchasers and any other selling security holders on the basis of the number of Registrable Securities owned by each such Purchaser and other selling security holders. The Purchasers’
right to have Registrable Securities included in the first registration statement filed by the Company may be deferred to the second registration statement filed by the Company, which deferral may be continued to the third or subsequent registration
statement so long as the registration statements are pursuant to underwritten offerings and the underwriter determines in good faith that marketing factors require exclusion of some or all of the Registrable Securities held by the Purchasers, but
such deferral shall be only to the extent of such required exclusion as determined by the underwriter; and 
 (iii) if the
registration is an underwritten registration, each Purchaser of Registrable Securities shall enter into an underwriting agreement in customary form with the underwriter and provide such information regarding Purchaser that the underwriter shall
reasonably request in connection with the preparation of the prospectus describing such offering, including completion of FINRA Questionnaires. 
 (c) Covenants with Respect to Registration. In connection with the registration in which the Registrable Securities are included, the Company and Purchaser covenant and agree as follows:

 (i) The foregoing registration rights shall be contingent on the Purchasers furnishing the Company with such appropriate
information as the Company shall reasonably request, including (A) such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it, as shall be reasonably
required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably request. At least seven days prior to the first anticipated filing date of any
Registration Statement, the Company shall notify each Purchaser of the information the Company requires from such Purchaser if such Purchaser elects to have any of the Registrable Securities included in the Registration Statement. A Purchaser shall
provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of such Registration Statement if it elects to have any of the Registrable Securities included in the Registration Statement. Each
Purchaser agrees to furnish to the Company a completed selling security holder questionnaire (a “Questionnaire”) in the form provided to it by the Company not less than two Business Days prior to the filing date of such Registration
Statement. The Company shall not be required to include the Registrable Securities of a Purchaser in a Registration Statement and shall not be required to pay any damages to such Purchaser who fails to furnish to the Company a fully completed
Questionnaire at least two Business Days prior to the filing date. The Company may require each selling Purchaser to furnish to the Company a certified statement as to the number of shares of Common Stock beneficially owned by it and, if required by
the Commission, the natural persons thereof that have voting and dispositive control over its shares of Common Stock. 
 (ii)
Each Purchaser, by its acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of a Registration Statement hereunder, unless such Purchaser
has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement. Each Holder agrees that, upon receipt of any notice from the Company that it must suspend sales of Common

  
 16 

 
Stock pursuant to the Registration Statement, it will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities,
until the Purchaser is advised by the Company that such dispositions may again be made. 
 (iii) Each Purchaser covenants and
agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it in connection with sales of Registrable Securities pursuant to a Registration Statement. 

(iv) The Company shall indemnify each Purchaser of Registrable Securities to be sold pursuant to the registration statement and each
person, if any, who controls such Purchaser within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against all loss, claim, damage, expense or liability (including reasonable expenses reasonably
incurred in investigating, preparing or defending against any claim) to which any of them may become subject under the Securities Act, the Exchange Act or otherwise, arising from such registration statement, except to the extent arising under
paragraph (v) below. 
 (v) Each Purchaser owning Registrable Securities to be sold pursuant to a registration statement,
and their successors and assigns, shall severally, and not jointly, indemnify the Company, its officers and directors and any underwriter, and each person, if any, who controls the Company or such underwriter within the meaning of Section 15 of
the Act or Section 20(a) of the Exchange Act, against all loss, claim, damage or reasonable expense or liability (including expenses reasonably incurred in investigating, preparing or defending against any claim) to which they may become
subject under the Securities Act, the Exchange Act or otherwise, arising (A) from information furnished by or on behalf of such Purchaser, or their successors or assigns, for inclusion in such registration statement, or (B) as a result of
use by the Purchaser of a registration statement that the Purchaser was advised to discontinue.

Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would no longer require or
otherwise permit such termination. 
 6.5 Certain Transactions and Confidentiality. Each Purchaser covenants that neither
it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales, of any of the Company’s securities during the period commencing with the execution of this Agreement
and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to Section 6.2. Each Purchaser covenants that until such time as the transactions contemplated by this Agreement are
publicly disclosed by the Company pursuant to Section 6.2, such Purchaser will maintain the confidentiality of the existence and terms of this transaction. Notwithstanding the foregoing and notwithstanding anything contained in this
Agreement to the contrary, the Company expressly acknowledges and agrees that unless a Purchaser possesses material, non-public information with respect to the Company, has entered into a confidentiality agreement with the Company, or otherwise is
restricted in its trading activities with respect to the Company’s Common Stock, (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company
after the time that the transactions contemplated by this Agreement are first publicly announced; (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of the Company in accordance with applicable
securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced; and (iii) no Purchaser shall have any duty of confidentiality to the Company or its Subsidiaries relating to this
Agreement after the initial disclosure of the transactions contemplated by this Agreement. 
 6.6 Integration. The
Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities to the
Purchasers in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers. 
 6.7 Transfer Restrictions. The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an
effective registration statement, to the Company or to an affiliate of a Purchaser or to an entity managed by a Purchaser (provided, in such case the prospective transferee agrees in all such instances in writing to be subject to the terms hereof to
the same extent as if he or she were an original Purchaser hereunder), the Company may require the transferor thereof to provide to the Company an opinion of counsel, the form and substance of which opinion shall be reasonably satisfactory to the
Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement.

 ARTICLE VII 
 INDEMNIFICATION 
 7.1 Indemnification. 

(a) The Company agrees to indemnify and hold harmless each Purchaser, its Affiliates, each of their officers, directors, employees and

Company in the this Agreement or in the other Transaction Agreements; (B) any breach of warranty or representation made by the Company in this Agreement or in the other Transaction Agreements; and (C) any and all actions, suits,

 19 

 (b) Each Purchaser agrees to indemnify and hold harmless the Company, its Affiliates, each
of their officers, directors, employees and agents and their respective successors and assigns, from and against any losses, damages, or expenses which are caused by or arise out of: (A) any breach or default in the performance by such
Purchaser of any covenant or agreement made by such Purchaser in this Agreement or in the other Transaction Agreements; (B) any breach of warranty or representation made by such Purchaser in this Agreement or in the other Transaction
Agreements; and (C) any and all actions, suits, proceedings, claims, demands, judgments, costs and expenses (including reasonable legal fees and expenses) incident to any of the foregoing. 

ARTICLE VIII 
 GENERAL 
 8.1 Termination. This Agreement may be terminated by any
Purchaser, as to such Purchaser’s obligations hereunder only and without any effect whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the Closing has not been consummated on
or before March 14, 2012; provided, however, that such termination will not affect the right of any party to sue for any breach by the other party (or parties). 
 8.2 Confidentiality. The Purchasers acknowledge that due to certain of the covenants contained herein or in the other Transaction Agreements, from time to time the Purchasers may come into
possession of confidential information of the Company, including material, non-public information relating to the Company. The Purchasers hereby agree that (i) they shall keep all such information strictly confidential, applying, at a minimum,
the same degree of care as it does to protect its own confidential information of a similar nature; (ii) shall only use such information in connection with the transactions contemplated by this Agreement; and (iii) shall not disclose any
of such information other than: (a) to the Purchaser’s employees, representatives, directors, attorneys, auditors, or Affiliates who are advised of the confidential nature of such information (so long as any of the foregoing persons agree
to be bound by the provisions of this Section), (b) to the extent such information presently is or hereafter becomes available on a non-confidential basis from any source of such information that is in the public domain at the time of
disclosure, (c) to the extent disclosure is required by law (including applicable securities law), regulation, subpoena or judicial order or any administrative body or commission to whose jurisdiction the Purchasers are subject (provided
that notice of such requirement or order shall be promptly furnished to the Company in advance of such disclosure), (d) to assignees or participants or prospective assignees or participants who agree to be bound by the provisions of this
Section, or (e) with the Company’s prior written consent. The Purchasers agree to be responsible for any breach of this agreement by any of the persons identified in Section 8.2(iii). The Purchasers are aware that, under certain
circumstances, the United States securities laws may prohibit a Person who has received material, non-public information from an issuer from purchasing or selling securities of such issuer or from communicating such information to any other Person
under circumstances in which it is reasonably foreseeable that such other Person is likely to purchase or sell such securities. 

8.3 Fees and Expenses. Except as expressly set forth in this Agreement to the contrary, each party shall pay the fees and expenses
of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. 

8.4 Amendments; Waivers. No provision of this Agreement may be amended or waived except in a written instrument signed,
(i) in the case of an amendment, by the Company and Purchasers 

  
 20 

 
representing a Majority in Interest, or (ii) in the case of a waiver, by the party against whom enforcement of any such waiver is sought; provided that, in the case of waiver by or on
behalf of all of the Purchasers, such written instrument shall be signed by Purchasers representing a Majority in Interest; and provided, further that any amendment that would (a) reduce the principal amount of any Note, (b) reduce the
percentage in aggregate principal amount of Notes outstanding necessary to modify or amend the Notes; or (c) modify this Section 8.4 shall, in each case, require the approval of each Purchaser to which such amendment shall apply. No
waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or
requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. 
 8.5 Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the
earliest of (a) the date of transmission, if such notice or communication is delivered via facsimile or e-mail at the facsimile number or e-mail address referred to in this Section 8.5 prior to 5:00 p.m. (Eastern time) on a Business Day,
(b) the next Business Day after the date of transmission, if such notice or communication is delivered via facsimile or e-mail at the facsimile number or e-mail address referred to in this Section 8.5 on a day that is not a Business Day or
later than 5:00 p.m. (Eastern time) on any Business Day, (c) the Business Day following the date of deposit with a nationally recognized overnight courier service or (d) upon actual receipt by the party to whom such notice is required to
be given. The addresses, facsimile numbers and e-mail addresses for such notices and communications are those set forth on the signature pages hereof, or such other address, facsimile number or e-mail address as may be designated in writing
hereafter, in the same manner, by the relevant party hereto. 
 8.6 Headings. The headings herein are for
convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. 
 8.7 Entire Agreement. This Agreement, together with the Notes and Warrants contain the entire understanding of the parties with respect to the subject matter hereof and supersede all prior
agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such agreements and exhibits. At or after the Closing, and without further consideration, the parties hereto will
make, do and execute and deliver, or cause to be made, done and executed and delivered, such further acts, deeds, assurances, documents and things as may be reasonably requested by any of the other parties hereto in order to give practical effect to
the intention of the parties hereunder. 
 8.8 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties and their respective successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of Purchasers representing a Majority in
Interest (other than by merger, consolidation or sale of all or substantially all of the Company’s assets). A Purchaser may assign any or all of its rights under this Agreement to any Person to whom the Purchaser assigns or transfers any
Securities, provided that such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions of this Agreement that apply to the “Purchasers.” 

8.9 No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective
successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person or entity. 
 8.10 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the

  
 21 

 
internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and
defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts
sitting in the City of New York, Borough of Manhattan. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of any dispute
hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit,
action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action or
proceeding to enforce any provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such action or proceeding. 
 8.11 Remedies. In addition to being entitled
to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under this Agreement. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of obligations contained in this Agreement and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law
would be adequate. 
 8.12 Execution. This Agreement may be executed by one or more of the parties hereto on
any number of separate counterparts (including by facsimile or e-mail transmission), all of which when taken together shall be considered one and the same agreement. In the event that any signature is delivered by facsimile transmission or
e-mail attachment, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or e-mail-attached signature page were an
original thereof. 
 8.13 Survival; Severability. All covenants and other agreements set forth in this
Agreement shall survive the Closing for the respective periods set forth therein and if no such period is specified until the maturity date of the Notes. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the
validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute
therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement. 
 8.14 Interpretation.
The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity to revise this Agreement and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the
drafting party shall not be employed in the interpretation of this Agreement or any amendments hereto. In addition, each and every reference to share prices and shares of capital stock in this Agreement shall be subject to adjustment for reverse and
forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the date of this Agreement. The word “including”, whenever used in this Agreement, shall be deemed to be followed
by the phrase “without limitation”. 

  
 22 

 8.15 Independent Nature of Purchasers’ Obligations and Rights. The obligations
of each Purchaser under any Transaction Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other
Purchaser under any Transaction Agreement. Nothing contained herein or in any other Transaction Agreement, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Agreements. Each Purchaser shall be
entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Agreements, and it shall not be necessary for any other Purchaser to be joined as an
additional party in any proceeding for such purpose. Each Purchaser has been advised to retain its own representation, including its own separate legal counsel, in their review and negotiation of the Transaction Agreements.
