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.

Regulation S-K. Each Purchaser acknowledges that, as set forth in the SEC Reports, certain officers, directors and holder of greater than 5% of the Company’s outstanding shares of Common Stock are the beneficial owners of an aggregate principal
amount of $4,850,000 of outstanding Senior Notes and that each such person may be a party to this Agreement and surrender the Senior Notes held by them in consideration of the issuance of the Units hereunder. 

(m) 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. 
 (n) 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 are not reasonably be expected to result in, individually or in the aggregate, a Material Adverse Effect. 

  
 10 

 (o) 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. 

(p) 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. 
 (q) 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 to the effect that the Company is not in compliance with the listing or maintenance requirements of the Nasdaq Stock 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 have a Material Adverse Effect, the rules and regulations of the Nasdaq Stock 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 Nasdaq Stock
Market. 
 (r) 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. 

(s) 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 

  
 11 

 
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 most recent periodic report filed for a completed fiscal quarter in accordance with the Exchange Act, 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.

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

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 Series D Preferred Shares, the Conversion Shares, the Warrants and the Warrant Shares, in the ordinary course of business for his, her or its own 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 Series D Preferred Shares, the Conversion Shares, the Warrants and the Warrant Shares except pursuant to sales registered

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 Securities,
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 Series D Preferred Shares, the Conversion Shares, the Warrants and the Warrant Shares, 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 Series D Preferred Shares, the Conversion Shares, the Warrants and the Warrant Shares, if any, indefinitely and is able to bear such
risk and to afford a complete loss of such investment. 
 (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

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 Series D Preferred Shares and Warrants 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 

  
 15 

 
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 Series D Preferred Shares, the Conversion Shares, the Warrants and the Warrant Shares or the fairness or suitability of the prospective investment in the Series D Preferred Shares, the
Conversion Shares, the Warrants and the Warrant Shares. 
 (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. 
 (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 Series D
Preferred Shares, the Conversion Shares, the Warrants and the Warrant Shares, 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. 
 (p) Representations Regarding Senior Notes. Each Purchaser that is paying some or all of its Subscription Amount by surrendering and cancelling Senior Notes hereby further represents and warrants
to the Company as follows: (i) such Purchaser is the beneficial and record owner of, with good and valid title to, the Senior Notes originally issued to it, free and clear of any and all pledges, liens, security interests, mortgage, claims,
charges, restrictions, options, title defects or encumbrances; (ii) such Purchaser has not, in whole or in part, (x) assigned, transferred, hypothecated, pledged or otherwise disposed of the Senior Notes or its rights in such Senior Notes
or under the Security Agreements, or (y) given any person or entity any transfer order, power of attorney or other authority of any nature whatsoever with respect to such Senior Notes which would limit the Holder’s power to transfer the
Senior Notes hereunder; (iii) such Purchaser has the sole right and power to vote and dispose of the Senior

Notes, and none of such Senior Notes is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting or transfer of any of the Senior Notes, except for
this Agreement; (iv) no additional consideration for any purpose shall be due to such Purchaser at Closing, with respect to the Senior Notes, other than the Securities; (vi) upon delivery of the Senior Notes to the Company for cancellation
(as contemplated by this Agreement), the Company will receive good and marketable title to the Senior Notes, free and clear of all pledges, liens, security interests, mortgage, claims, charges, restrictions, options, title defects or encumbrances;

incurred any liability for any brokerage or investment banking fees, commissions, finders’ structuring fees, financial advisory fees or other similar fees in connection with any of the transactions contemplated by this Agreement.

Notwithstanding anything in this Purchase Agreement or any of the other agreements and instruments executed in accordance with this Purchase Agreement to 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 acquire or purchase (whether upon 

  
 19 

 
conversion of the Series D Preferred Shares, payment of dividends on the Series D Preferred Shares, or 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, without limitation, Nasdaq Listing Rule 5635) and such other Trading Market on which the Company’s shares of Common Stock are then listed or quoted for trading (the
“Exchange Cap”). Accordingly, if stockholder approval would be required under the applicable listing rules of the Nasdaq Stock Market or such other Trading Market on which the Company’s shares of Common Stock are then listed or
quoted for trading (the “Principal Market”), then 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
multiplied by a fraction, the numerator of which is the Units issued to the Purchaser hereunder on the Closing Date and the denominator of which is the total number of Units issued to all purchasers in the Offering on the Closing Date (with respect
to each purchaser, the “Exchange Cap Allocation”). In the event that Purchaser shall sell or otherwise transfer any of the securities comprising the Units, the transferee thereof shall be allocated a pro rata portion of
Purchaser’s Exchange Cap Allocation, and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. 

6.9 Stockholder Approval. Solely in the event that the Company determines that it is required in order to permit the full
conversion of the Series D Preferred Shares (including in connection with the payment of dividends on the Series D Preferred Shares) or the full exercise of the Warrants issued pursuant to this Agreement into shares of Common Stock in accordance
with applicable listing rules of the Principal Market (the “Stockholder Approval”), the Company shall, following its determination that such Stockholder Approval is required, at its next annual meeting of stockholders scheduled
subsequent to such determination, 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 Series D Preferred Shares and 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 conversion of the Series D Preferred Shares or 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 Series D Preferred Shares and Warrants in excess of 19.99% of the issued and outstanding Common Stock of the Company. 
 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 agents and their respective successors and assigns, from and against

(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, proceedings, claims, demands, judgments, costs and expenses (including

 20 

 (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. Solely in the event that the Closing has
not been consummated on or before June 30, 2013, 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; provided, however, that (a) any Purchaser may elect to extend the foregoing date solely with respect to its purchase of the Securities hereunder and (b) any 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. 

  
 21 

 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 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 that any amendment that would 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 other Transaction Agreements 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. 

  
 22 

 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 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
representations and warranties made by the Company and each of the Purchasers herein will survive the execution of this Agreement, the Closing and the delivery to the Purchasers of the Securities being purchased and the payment therefor until the
first anniversary of the Closing Date, except for those representations and warranties which speak as of a specific date. 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 first anniversary of the Closing Date. Notwithstanding anything to the contrary contained herein, Sections 7.1 and 8.4 shall survive for the applicable statute of limitations. 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 Replacement of Certificates. If any certificate evidencing the securities issued or issuable hereunder is mutilated, lost,
stolen or destroyed, the Company shall issue or cause to be issued in 

  
 23 

 
exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity or security, if requested. The applicant for a new certificate under such circumstances shall also pay any reasonable third-party costs (including
customary indemnity) associated with the issuance of such replacement certificates. 
 8.15 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”. 
 8.16 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.
