 4.26 Transactions with Affiliates. Except as disclosed in the SEC Filings and except
as would not be required to be disclosed in the SEC Filings, none of the officers or directors of the Company and, to the Company’s Knowledge, none of the employees of the Company is presently a party to any transaction with the Company or any
Subsidiary (other than as holders of stock options and/or warrants, and for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for
rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the Company’s Knowledge, any entity in which any officer, director, or any such employee has a substantial
interest or is an officer, director, trustee or partner. 
 4.27 Internal Controls. The Company is in material compliance
with the provisions of the Sarbanes-Oxley Act of 2002 currently applicable to the Company. The Company and the Subsidiaries maintain 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 GAAP and to maintain asset accountability,
(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 to any differences. The Company has established disclosure controls and procedures (as defined in 1934 Act Rules 13a-15(e) and 15d-15(e)) for the Company and designed such disclosure controls and procedures to ensure
that material information relating to the Company, including the Subsidiaries, is made known to the certifying officers by others within those entities, particularly during the period in which the Company’s most recently filed periodic report
under the 1934 Act, as the case may be, is being prepared. The Company’s certifying officers have evaluated the effectiveness of the Company’s controls and procedures as of the end of the period covered by the most recently filed periodic
report under the 1934 Act (such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the 1934 Act the conclusions of the certifying officers about the effectiveness of the disclosure
controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s internal controls (as such term is defined in Item 308 of Regulation S-K) or,
to the Company’s Knowledge, in other factors that could significantly affect the Company’s internal controls. The Company maintains and will continue to maintain a standard system of accounting established and administered in accordance
with GAAP and the applicable requirements of the 1934 Act. 
 4.28 Investment Company. The Company is not required to be
registered as, and is not an Affiliate of, and immediately following the Closing will not be required to register as, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 

Each of the Investors acknowledges and agrees that the Company has not made any representations or warranties with respect to the
transactions contemplated hereby other than those specifically set forth in this Section 4. Each of the Investors further acknowledges and agrees that neither the Company nor any other Person has made any representation or warranty,
expressed or implied, as to the accuracy or completeness of any information received by any such Investor which constitutes or may be deemed to constitute a projection, estimate or other forecast and certain business plan information, except that
such information was prepared in good faith and based upon assumptions that the Company believes to have been reasonable at the time such information, if any, was provided to the applicable Investor.

representations and warranties contained in this Agreement. 
 5.7 Restricted Securities. Such Investor understands that
the Securities are characterized as “restricted securities” under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and

as the Company and that each of the other Investors shall have an independent right to assert any claims against such Investor arising out of any breach or violation of the provisions of this Section 5.12.

together with its Affiliates, will not beneficially own or be deemed the beneficial owner of more than 19.999% of all such Common Stock and other voting securities of the

7. Covenants and Agreements. 
 7.1 Reservation of Common Stock. The Company shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of providing for the

 7.2 Reports. The Company will furnish to the Investors and/or their assignees such information relating to the Company and its Subsidiaries as from time to time may reasonably be requested by the
Investors and/or their assignees; provided, however, that the Company shall not disclose material nonpublic information to the Investors, or to advisors to or representatives of the Investors, unless prior to disclosure of such information the
Company identifies such information as being material nonpublic information and provides the Investors, such advisors and representatives with the opportunity to accept or refuse to accept such material nonpublic information for review and any
Investor wishing to obtain such information enters into an appropriate confidentiality agreement with the Company with respect thereto.

 -16-

 7.6 Listing of Underlying Shares and Related Matters. Promptly following the date
hereof, the Company shall take all necessary action to cause the Shares and the Warrant Shares to be listed on Nasdaq no later than the Closing Date. Further, if the Company applies to have its Common Stock or other securities traded on any other

efforts to continue the listing and trading of its Common Stock on Nasdaq and, in accordance, therewith, will use commercially reasonable efforts to comply in all respects with the Company’s reporting, filing and other obligations under the
bylaws or rules of such market or exchange, as applicable. 
 7.7 Termination of Covenants. The provisions of Sections
7.2 through 7.5 shall terminate and be of no further force and effect on the date on which the Company’s obligations under the Registration Rights Agreement to register or maintain the effectiveness of any registration covering the
Registrable Securities (as such term is defined in the Registration Rights Agreement) shall terminate. 
 7.8 Removal of
Legends. Upon the earlier of (i) the sale or disposition of any Securities by an Investor pursuant to Rule 144 or pursuant to any other exemption under the 1933 Act such that the purchaser acquires freely tradable securities or
(ii) any Securities of the Investor becoming eligible to be sold without restriction pursuant to Rule 144, upon the written request of such Investor, the Company shall or, in the case of Common Stock, shall cause the transfer agent for the
Common Stock (the “Transfer Agent”) to issue replacement certificates representing such Securities. From and after the earlier of such dates, upon an Investor’s written request, the Company shall promptly cause certificates
evidencing the Investor’s Securities to be replaced with certificates which do not bear such restrictive legends, and Warrant Shares subsequently issued upon due exercise of the Warrants shall not bear such restrictive legends provided the
provisions of either clauses (i) or (ii) above, as applicable, are satisfied with respect thereto. In addition, upon the earlier of (a) registration of the Shares and the Warrant Shares for resale pursuant to the
Registration Rights Agreement or (b) the Shares and/or the Warrant Shares becoming eligible to be sold without restriction pursuant to Rule 144, the Company shall (1) deliver to the Transfer Agent irrevocable instructions that the Transfer
Agent shall reissue a certificate representing shares of Common Stock without legends upon receipt by such Transfer Agent of the legended certificates for such shares, together with either (A) a customary representation by the Investor that
Rule 144 applies to the shares of Common Stock represented thereby or (B) a statement by the Investor that such Investor has sold the shares of Common Stock represented thereby in accordance with the Plan of Distribution contained in the
Registration Statement, and (2) cause its counsel to deliver to the Transfer Agent one or more blanket opinions to the effect that the removal of such legends in such circumstances may be effected under the 1933 Act. When the Company is
required to cause an unlegended certificate to replace a previously issued legended certificate, if: (x) the unlegended certificate is not delivered to an Investor within three (3) Business Days of submission by that Investor of a legended
certificate and supporting documentation to the Transfer Agent as provided above and (y) prior to the time such unlegended certificate is received by the Investor after such three (3) Business Day period, the Investor, or any third party
on behalf of such Investor or for the Investor’s account, purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Investor of shares represented by such certificate (a
“Buy-In”), then the Company shall pay in cash to the Investor (for costs incurred either directly by such Investor or on behalf of a third party) the amount by which the total purchase price paid for Common Stock as a result of the
Buy-In (including brokerage commissions, if any) exceeds the proceeds received by such Investor as a result of the sale to which such Buy-In relates. The Investor shall provide the Company written notice together with a reasonably detailed summary
indicating the amounts payable to the Investor in respect of the Buy-In. 
 7.9 Board of Directors. Promptly following
the Closing, the Company shall cause Joseph De Perio to be appointed as a member of the Board of Directors of the Company with 

  
 -17-

 
compensation at the same time and in the same manner as the existing members of the Board of Directors of the Company for so long as he serves as a director. The Company and the Investors
acknowledge and agree that Mr. De Perio is not a representative of any Investor other than the Clinton Group, Inc. 
 7.10
Subsequent Equity Sales. 
 (a) From the date hereof until six (6) months after the Closing Date, without the
consent of the Required Investors, neither the Company nor any Subsidiary shall issue shares of Common Stock or Common Stock Equivalents. Notwithstanding the foregoing, the provisions of this Section 7.10(a) shall not apply to
(i) the issuance of Common Stock or Common Stock Equivalents upon the conversion or exercise of any securities of the Company or a Subsidiary outstanding on the date hereof or issued pursuant to the Engagement Letter, provided that the terms of
such security are not amended after the date hereof to decrease the exercise price or increase the Common Stock or Common Stock Equivalents receivable upon the exercise, conversion or exchange thereof, (ii) the issuance of any Common Stock or
Common Stock Equivalents pursuant to any Company equity incentive plan approved by the Company’s shareholders and in place as of the date hereof, or (iii) the issuance of Common Stock or Common Stock Equivalents in a strategic transaction,
including, without limitation, joint ventures, manufacturing, marketing, licensing or distribution arrangements or technology transfer or development arrangements, in each case approved by a majority of the disinterested directors, provided any such
issuance shall only be to a Person which is, itself or through its subsidiaries, an operating company in a business synergistic with the business of the Company and in which the Company receives benefits in addition to the investment of funds, but
shall not include a transaction in which the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing in securities. 

(b) From the date hereof until the earlier of (i) three (3) years from the Closing Date or (ii) such time as no Investor
holds any of the Securities, the Company shall be prohibited from effecting or entering into an agreement to effect any “Variable Rate Transaction”. The term “Variable Rate Transaction” shall mean a transaction in which
the Company issues or sells (a) any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either (1) at a conversion, exercise or exchange
rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities, or (2) with a conversion, exercise or
exchange price that is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or
the market for the Common Stock or (b) enters into any agreement, including, but not limited to, an equity line of credit, whereby the Company may sell securities at a future determined price. For the avoidance of doubt, the issuance of a
security which is subject to customary anti-dilution protections, including where the conversion, exercise or exchange price is subject to adjustment as a result of stock splits, reverse stock splits and other similar recapitalization or
reclassification events, shall not be deemed to be a “Variable Rate Transaction.” 
 (c) The Company shall not, and
shall use its commercially reasonable efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the 1933 Act) that will
be integrated with the offer or sale of the Securities in a manner that would require the registration under the 1933 Act of the sale of the Securities to the Investors, or that will be integrated with the offer or sale of the Securities for
purposes of the rules and regulations of any trading market such that it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

  
 -18-

 7.11 Equal Treatment of Investors. No consideration shall be offered or paid to any
Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same consideration is also offered to all of the parties to the Transaction Documents. For clarification purposes, this provision
constitutes a separate right granted to each Investor by the Company and negotiated separately by each Investor, and is intended for the Company to treat the Investors as a class and shall not in any way be construed as the Investors acting in
concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise. 
 8. Survival and
Indemnification. 
 8.1 Survival. The representations, warranties, covenants and agreements contained in this
Agreement shall survive the Closing of the transactions contemplated by this Agreement until the expiration of the applicable statute of limitations. 
 8.2 Indemnification. The Company agrees to indemnify and hold harmless each Investor and its Affiliates and their respective directors, officers, trustees, members, managers, employees and agents,
and their respective successors and assigns, from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorney fees and disbursements (subject to Section 8.3 below) and
other expenses incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) (collectively, “Losses”) to which such Person may become
subject as a result of any breach of any representation, warranty, covenant or agreement made by or to be performed on the part of the Company under the Transaction Documents, and will reimburse any such Person for all such amounts as they are
incurred by such Person. 
 8.3 Conduct of Indemnification Proceedings. Any person entitled to
indemnification hereunder shall (i) give prompt notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of
such counsel shall be at the expense of such person unless (a) the indemnifying party has agreed to pay such fees or expenses, (b) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably
satisfactory to such person or (c) in the reasonable judgment of any such person, based upon written advice of its counsel, a conflict of interest exists between such person and the indemnifying party with respect to such claims (in which case,
if the person notifies the indemnifying party in writing that such person elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such claim on behalf of
such person); and provided, further, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations hereunder, except to the extent that such failure to give
notice shall materially adversely affect the indemnifying party in the defense of any such claim or litigation. It is understood that the indemnifying party shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or
expenses of more than one separate firm of attorneys at any time for all such indemnified parties. No indemnifying party will, except with the consent of the indemnified party, consent to entry of any judgment or enter into any settlement that does
not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation. The Company will not be liable to any indemnified party under this
Agreement (x) for any settlement by such indemnified party effected without the Company’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed, or (y) for any Losses incurred by such indemnified
party which a court of competent jurisdiction determines in a final judgment which is not subject to further appeal are solely attributable to (A) a breach of any of the representations, warranties, covenants

  
 -19-

 
or agreements made by such indemnified party under this Agreement or in any other Transaction Document or (B) the fraud, gross negligence or willful misconduct of such indemnified party.

 9. Miscellaneous. 
 9.1 Successors and Assigns. This Agreement may not be assigned by a party hereto without the prior written consent of the Company or the Investors, as applicable, provided, however, that an
Investor may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to a third party acquiring some or all of its Securities in a transaction complying with applicable securities laws without the prior written
consent of the Company or the other Investors. The provisions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties. Without limiting the generality of the foregoing, in
the event that the Company is a party to a merger, consolidation, share exchange or similar business combination transaction in which the Common Stock is converted into the equity securities of another Person, from and after the effective time of
such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Common Stock” shall
be deemed to refer to the securities received by the Investors in connection with such transaction. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and
assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 
 9.2 Counterparts; Faxes. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same

9.7 Publicity. Except as set forth below, no public release or announcement concerning the transactions
contemplated hereby shall be issued by the Company or the Investors without the prior consent of the Company (in the case of a release or announcement by the Investors) or the Investors (in the case of a release or announcement by the Company)
(which consents shall not be unreasonably withheld), except as such release or announcement may be required by law or the applicable rules or regulations of any securities exchange or securities market, in which case the Company or the Investors, as
the case may be, shall allow the Investors or the Company, as applicable, to the extent reasonably practicable in the circumstances, reasonable time to comment on such release or announcement in advance of such issuance. By 8:30 a.m. (New York City

or Nasdaq. 
 9.8 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be enforceable to the maximum extent
permitted by applicable 

  
 -21-

 
law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by applicable
law, the parties hereby waive any provision of law which renders any provision hereof prohibited or unenforceable in any respect. 
 9.9 Entire Agreement. This Agreement, including the Exhibits and the Disclosure Schedules, and the other Transaction Documents constitute the entire agreement among the parties hereof with respect
to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof. 

9.10 Further Assurances. The parties shall execute and deliver all such further instruments and documents and take all such other
actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained. 
 9.11 Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York applicable to
agreements made and to be performed entirely within the State of New York (except to the extent the provisions of the California Corporations Code would be mandatorily applicable to the issuance of the Shares, the Warrants or the Warrant Shares).
Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York County and the United States District Court for the Southern District of New York for the purpose of any suit,
action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world
by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such
court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum. TO THE EXTENT ALLOWABLE UNDER APPLICABLE LAW, EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS AGREEMENT AND REPRESENTS THAT COUNSEL HAS BEEN
CONSULTED SPECIFICALLY AS TO THIS WAIVER. 
 9.12 Independent Nature of Investors’ Obligations and Rights. The
obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any
Transaction Document. The decision of each Investor to purchase Securities pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein or in any Transaction Document, and no
action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or
as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and
that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Investor 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 Documents, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such
purpose. Each Investor has been represented by its own separate legal counsel in their review and negotiation of the Transaction Documents. Each Investor acknowledges that Morrison & 

  
 -22-

 
Foerster LLP is legal counsel solely to the Placement Agent and not any Investor. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the
purpose of closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor.
