December 31, 2007 (the “Annual Report”) (collectively, the “Subsidiaries”). Each of the Subsidiaries has been duly organized and is validly existing as an entity in good standing under the laws of the
jurisdiction of its organization, with corporate power and authority to own or lease its properties and conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus. The Subsidiaries are the only
subsidiaries, direct or indirect, of the Company. The Company and each of the Subsidiaries are duly qualified to transact business in all jurisdictions in which the conduct of their business requires such qualification, except where the failure to
be so qualified would not reasonably be expected to (i) result in any material adverse change, or any development that would reasonably be expected to result in a material adverse change, in or affecting the business, results of operations, or
financial condition of the Company and of the Subsidiaries taken as a whole, whether or not occurring in the ordinary course of business, or (ii) prevent, burden or impair the consummation of the transactions contemplated by this Agreement
(collectively a “Material Adverse Effect”). The outstanding shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are owned by the Company or another
Subsidiary free and clear of all liens, encumbrances and equities and claims, except as described in the Registration Statement and the General Disclosure Package; and no options, warrants or other rights to purchase, agreements or other obligations
to issue or other rights to convert any obligations into shares of capital stock or ownership interests in the Subsidiaries are outstanding.

Instructions (as defined in Section 5(b)), and each of the other agreements entered into by the parties hereto in connection with the transactions contemplated by this Agreement (collectively, the “Transaction Documents”) and
to issue the Securities in accordance with the terms hereof and thereof. The execution and delivery of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby, including,
without limitation, the issuance of the Notes, the reservation for issuance and the issuance of the Conversion Shares issuable upon conversion of the Notes have been duly authorized by the Company’s Board of Directors, and no further filing,
consent, or authorization is required by the Company’s Board of Directors or its stockholders. This Agreement and the other Transaction Documents of even date herewith have been duly executed and delivered by the Company, and constitute the
legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies. 
 (c) Issuance of Securities. (i) The outstanding shares of Common Stock of the Company have been duly authorized and validly issued and are

Common Stock shall have been duly authorized and reserved for issuance which equals or exceeds 120% of the aggregate of the maximum number of shares of Common Stock issuable as of the Closing Date upon conversion of the Notes. The offering or sale
of the Securities as contemplated by this Agreement does not give rise to any rights, other than those which have been waived or satisfied, for or relating to the registration of any shares of Common Stock. Upon conversion in accordance with the
terms of the Notes, the Conversion Shares will be validly issued, fully paid and nonassessable and free from all preemptive or similar rights, taxes, liens and charges with respect to the issue thereof, with the holders being entitled to all rights
accorded to a holder of Common Stock. 
 (ii) Assuming the accuracy of the representations and warranties of Investor set forth in
Section 2 of this Agreement, the offer, issue, sale and delivery of Securities under the circumstances contemplated by this Agreement constitutes or will constitute an exempt transaction under the Securities Act of 1933 (the “1933
Act”), as now in effect, and registration of the Securities under the Securities Act, is not required. 
 (d) Equity
Capitalization. As of the date hereof and as of the Initial Closing Date, the Company has or will have, as the case may be, an authorized, issued and outstanding capitalization as is set forth in Schedule 3(d) hereto (subject to the

Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the Transaction Documents, an Investor shall have the right to make a public
disclosure, in the form of a press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company, 

  

 - 19 - 








 
its Subsidiaries, or any of its or their respective officers, directors, employees or agents. No Investor shall have any liability to the Company, its
Subsidiaries, or any of its or their respective officers, directors, employees, stockholders or agents for any such disclosure. Subject to the foregoing, neither the Company, its Subsidiaries nor any Investor shall issue any press releases or any
other public statements with respect to the transactions contemplated hereby; provided, however, that the Company shall be entitled, without the prior approval of any Investor, to make any press release or other public disclosure with respect to
such transactions (i) in substantial conformity with the 8-K Filing and contemporaneously therewith and (ii) as is required by applicable law, regulation or any Eligible Market on which the Company’s securities are then listed or
quoted (provided that in the case of clause (i) the Investor shall be consulted by the Company in connection with any such press release or other public disclosure prior to its release). Without the prior written consent of any applicable
Investor, neither the Company nor any of its Subsidiaries or affiliates shall disclose the name of such Investor in any filing, announcement, release or otherwise other than in connection with the Registration Statement unless such disclosure is

price of any such security cannot be less than the then applicable Conversion Price (as defined in the Notes) with respect to the Common Stock into which any Note is convertible. For so long as any Notes remain outstanding, the Company shall not, in
any manner, enter into or affect any Dilutive Issuances (as defined in the Notes) if the effect of such Dilutive Issuance is to cause, or but for the Securities Limitations (as defined below) would cause, the Company to be required to issue upon
conversion of any Note any shares of Common Stock in excess of that number of shares of Common Stock which the Company may issue upon conversion of the Notes without breaching the Company’s obligations under the rules or regulations of the
Principal Market, in each case without giving effect to (x) the limitations on conversion contained in the Notes and (y) the application of any Conversion Floor Price (as defined in the Notes), (the “Securities
Limitations”). For so long as any Notes are outstanding, unless or until the stockholder approval required by the Principal Market (as defined below) has been obtained, the Company shall not take any action if the effect of such action
would be to cause the Conversion Price to be reduced below the Conversion Floor Price without giving effect to any Securities Limitations.

Schedule of Investor attached hereto and ending at such time that all of the Securities can be sold without the requirement to be in compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, if a
registration statement is not available for the resale of all of the Securities and the Company shall fail for any reason to satisfy the current public information requirement under Rule 144(c)(1) (a “Public Information Failure”)
then, as partial relief for the damages to any holder of Securities by reason of any such delay in or reduction of its ability to sell the Securities (which remedy shall not be exclusive of any other remedies available at law or in equity), the
Company shall pay to each such holder an amount in cash equal to two percent (2.0%) of the aggregate Purchase Price of such holder’s Securities on the day of a Public Information Failure and on every thirtieth day (pro rated for periods
totaling less than thirty days) thereafter until the earlier of (i) the date such Public Information Failure is cured and (ii) such time that such public information is no longer required pursuant to Rule 144. The payments to which a
holder shall be entitled pursuant to this Section 4(l) are referred to herein as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of (I) the last day of the calendar

Notes and under the other Security Documents (in such capacity, the “Collateral Agent”), and (b) authorizes the Collateral Agent (and its officers, directors, employees and agents) to take such action on such Investor’s
behalf in accordance with the terms hereof and thereof. The Collateral Agent shall not have, by reason hereof or any of the other Transaction Documents, a fiduciary relationship in respect of any Investor. Neither the Collateral Agent nor any of its
officers, directors, employees and agents shall have any liability to any Investor for any action taken or omitted to be taken in connection hereof or any other Transaction Document except to the extent caused by its own gross negligence or willful
misconduct, and the Investor agrees to defend, protect, indemnify and hold harmless the Collateral Agent and all of its officers, directors, employees and agents (collectively, the “Collateral Agent Indemnitees”) from and against
any losses, damages, liabilities, obligations, penalties, actions, judgments, suits, fees, costs and expenses (including, without limitation, reasonable attorneys’ fees, costs and expenses) incurred by such Collateral

Agent Indemnitee, whether direct, indirect or consequential, arising from or in connection with the performance by such Collateral Agent Indemnitee of the
duties and obligations of Collateral Agent pursuant hereto or any of the Transaction Documents. The Collateral Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and
shall be fully protected in so acting or refraining from acting) upon the instructions of the holders of a majority in principal amount of the Notes then outstanding, and such instructions shall be binding upon all holders of Notes; provided,
however, that the Collateral Agent shall not be required to take any action which, in the reasonable opinion of the Agent, exposes the Agent to liability or which is contrary to this Agreement or any other Transaction Document or applicable law. The
Collateral Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the
proper Person, and with respect to all matters pertaining to this Agreement or any of the other Transaction Documents and its duties hereunder or thereunder, upon advice of counsel selected by it. 
 (n) Successor Collateral Agent. 
 (i) The Collateral Agent may resign from the performance of all its functions and duties hereunder and under the other Transaction Documents at any time by giving at least thirty (30) Business Days’ prior
written notice to the Company and each holder of Notes. Such resignation shall take effect upon the acceptance by a successor Collateral Agent of appointment pursuant to clauses (ii) and (iii) below or as otherwise provided below. In
addition, at any time and from time to time following the repayment by Elitech of all “Guaranteed Obligations” as defined in the Elitech Guarantee in accordance with the terms of thereof, the holders of a majority in principal amount of
the Notes may, by giving at least ten (10) Business Days’ prior written notice to the Company and the Collateral Agent, remove the Collateral Agent as collateral agent and appoint a successor collateral agent. 
 (ii) Upon any such notice of resignation, the holders of a majority in principal amount of the Notes then outstanding shall appoint a
successor collateral agent. Upon the acceptance of any appointment as collateral agent hereunder by a successor collateral agent, such successor collateral agent shall thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the collateral agent, and the Collateral Agent shall be discharged from its duties and obligations under this Agreement and the other Transaction Documents. After the Collateral Agent’s resignation hereunder as the collateral
agent or the removal of the Collateral Agent and appointment of a successor collateral agent, the provisions of this Section 4(n) shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Collateral Agent
under this Agreement and the other Transaction Documents. 
 (iii) If a successor collateral agent shall not have been so
appointed within said thirty (30) Business Day period, the Collateral Agent shall then appoint a successor collateral agent who shall serve as the collateral agent until such time, if any, as the holders of a majority in principal amount of the
Notes then outstanding appoint a successor collateral agent as provided above. 
  

 - 22 - 








 (o) Appointment of Special Co-Collateral Agent. 
 (i) Notwithstanding any other provisions of this Agreement, for the purpose of holding and or liquidating any Collateral in a foreign
jurisdiction or following the occurrence of, and during the continuation of, an Event of Default under the Notes and any other actions permitted to be taken by the Collateral Agent pursuant to the Security Documents, if the Collateral Agent
reasonably believes that such action is either (A) required by applicable law, rule or regulation or (B) is otherwise in the best interests of the holders of the Notes, the Collateral Agent shall have the power and may execute and deliver
all instruments necessary to appoint one or more Persons to act as a co-collateral agent or co-collateral agents hereunder, or separate collateral agent or separate collateral agents hereunder (the “Special Co-Collateral Agent”), in
each case exclusively in such jurisdiction or jurisdictions, and to vest in such Special Co-Collateral Agent, in such capacity and for the benefit of the Investor, such title hereunder, or any part hereof, in each case exclusively in such
jurisdiction or jurisdictions, and subject to the other provisions of this Section 4(o), such powers, duties, obligations, rights and trusts in such jurisdiction or jurisdictions as the Collateral Agent, as applicable may reasonably consider
necessary or desirable. Each Special Co-Collateral Agent hereunder shall be authorized under applicable law to act as the Special Co-Collateral Agent. Any Special Co-Collateral Agent may be removed at any time by the written direction of either
(x) the Collateral Agent or (y) the Required Holders (as defined in the Notes). If at any time a Special Co-Collateral Agent shall cease to be eligible to perform its obligations as a Special Co-Collateral Agent in accordance with the
provisions of this Section, it shall resign immediately in the manner and with the effect specified in Section 4(n) above. If any Special Co-Collateral Agent shall cease to exist, become insolvent, resigns or is removed, all of its estates,
properties, rights, remedies and trusts grated hereunder shall vest in and be exercised by the Collateral Agent to the extent permitted by law, without the appointment of a new or successor Special Co-Collateral Agent. The Investor hereby consents
to the appointment of the Investor as the Special Co-Collateral Agent with respect to the assets of the NAD Sub. 
 (ii) Any
notice, request or other writing given to the Collateral Agent shall be deemed to have been given to each of the then Special Co-Collateral Agent as effectively as if given to each of them. Every instrument appointing any Special Co-Collateral Agent
shall refer to this Agreement or the Security Documents, if applicable, and the conditions of this Section 4(o). Each Special Co-Collateral Agent upon its acceptance of the trusts conferred, shall, subject to the provisions of this
Section 4(o) hereof, be vested with the estates or property specified in its instrument of appointment, either jointly with the Collateral Agent, or separately, as may be provided therein, subject to all the provisions of this Agreement or the
Security Documents, as applicable. Every such instrument shall be filed with the Collateral Agent. 
 (iii) The Special
Co-Collateral Agent shall not have, by reason hereof or any of the other Transaction Documents, a fiduciary relationship in respect of any Investor. Neither the Special Co-Collateral Agent nor any of its officers, directors, employees and agents
shall have any liability to any Investor for any action taken or omitted to be taken in connection hereof or any other Transaction Document except to the 

  

 - 23 - 








 
extent caused by its own gross negligence or willful misconduct, and the Investor agrees to defend, protect, indemnify and hold harmless the Special
Co-Collateral Agent and all of its officers, directors, employees and agents (collectively, the “Special Co-Collateral Indemnitees”) from and against any losses, damages, liabilities, obligations, penalties, actions, judgments,
suits, fees, costs and expenses (including, without limitation, reasonable attorneys’ fees, costs and expenses) incurred by such Special Co-Collateral Indemnitee, whether direct, indirect or consequential, arising from or in connection with the
performance by such Special Co-Collateral Indemnitee of the duties and obligations of Special Co-Collateral Agent pursuant hereto or any of the Transaction Documents. The Special Co-Collateral Agent shall not be required to exercise any discretion
or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the holders of a majority in principal amount of the Notes then outstanding,
and such instructions shall be binding upon all holders of Notes; provided, however, that the Special Co-Collateral Agent shall not be required to take any action which, in the reasonable opinion of the Agent, exposes the Agent to liability or which
is contrary to this Agreement or any other Transaction Document or applicable law. The Special Co-Collateral Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any telephone message
believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect to all matters pertaining to this Agreement or any of the other Transaction Documents and its duties hereunder or
thereunder, upon advice of counsel selected by it. 
 (p) Intentionally Omitted 
 (q) Intentionally Omitted 
 (r)
Stockholder Approval. The Company shall provide each stockholder entitled to vote at the next meeting of stockholders of the Company (the “Stockholder Meeting”), which shall be promptly called and held not later than the
earlier of (i) the date of the special meeting of stockholders of the Company as set forth in the proxy statement to be filed in connection with the transactions contemplated under the Share Exchange Agreement, dated as of the date hereof
between the Company, Elitech and the stockholders of Elitech and (ii) March 31, 2009 (the “Stockholder Meeting Deadline”), a proxy statement, substantially in the form which has been previously reviewed by the Investor and
a counsel of its choice, soliciting each such stockholder’s affirmative vote at the Stockholder Meeting for approval of resolutions (the “Stockholder Resolutions”) providing for the Company’s issuance of all of the
Securities as described in the Transaction Documents in accordance with applicable law and the rules and regulations of the Principal Market (such affirmative approval being referred to herein as the “Stockholder Approval”), and the
Company shall use its best efforts to solicit its stockholders’ approval of such resolutions (which efforts shall include, without limitation, the requirement to hire a nationally recognized proxy solicitor) and to cause the Board of Directors
of the Company to recommend to the stockholders that they approve such resolutions. The Company shall be obligated to seek to obtain the Stockholder Approval by the Stockholder Meeting Deadline. 
 (s) Italian Security. As soon as reasonably practicable but in no event later than October 15, 2008, (i) the Company shall grant a
pledge in 100% of the capital stock of the 

  

 - 24 - 








 
NAD Sub pursuant to the Pledge As Collateral On Share of a Limited Company Agreement, whereby the Company establishes a valid, effective and perfected
pledge, pursuant to Italian law, over the entire quota held by the Company, having a total face value of €50,000.00 and representing a 100% stake in the entire share capital of the NAD Sub, and over all the new quotas as may be issued from time
to time by the NAD Sub, the form and substance of which shall be reasonably satisfactory to the Investor (the “NAD Sub Pledge Agreement”), which shall be executed before a notary public in Italy and the Company shall carry out all
such other actions as are required by Italian law to perfect and ensure the effectiveness of such pledge no later than October 15, 2008, (ii) the Company shall cause the NAD Sub to grant a pledge pursuant to the Pledge over Bank Account
Agreement whereby the NAD Sub shall grant a pledge over the account, the amounts at any time credited on the account and the claims of the Company from the restitution of the balance from time to time existing on the account, jointly and pro
indiviso basis, the form and substance of which shall be reasonably satisfactory to the Investor (the “Bank Account Pledge Agreement”) in (x) the balance of bank account number 100000061933 at Intesa San Paolo, Agenzia 3,
Corso Sempione 65/A, Milan and (y) the balance of bank account number 000000005083 at Banca Popolare di Bergamo, Agenzia Via Foppa, Via Foppa 26, Milan, and the Company shall cause the NAD Sub to carry out all such other actions as are required
by Italian law to perfect and ensure the effectiveness of such pledges (collectively, the “Bank Account Pledge Agreements”) no later than October 15, 2008 and (iii) the Company shall cause Ughi e Nunziante, the
Company’s Italian law firm, to deliver an opinion to the Investor, dated as of the October 15, 2008, in form and substance acceptable to the Investor. 
 5. REGISTER; TRANSFER AGENT INSTRUCTIONS. 
 (a) Register. The Company shall maintain at its
principal executive offices (or such other office or agency of the Company as it may designate by notice to each holder of Securities), a register for the Notes in which the Company shall record the name and address of the Person in whose name the
Notes have been issued (including the name and address of each transferee), the principal amount of Notes held by such Person, the number of Conversion Shares issued and issuable upon conversion of the Notes held by such Person. The Company shall
keep the register open and available at all times during business hours for inspection of any Investor or its legal representatives. 
 (b)
Transfer Agent Instructions. The Company shall issue irrevocable instructions to the Transfer Agent, and any subsequent transfer agent, in the form of Exhibit G attached hereto (the “Irrevocable Transfer Agent
Instructions”). The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5 will be given by the Company to the Transfer Agent, and any subsequent
transfer agent with respect to the Securities, and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other Transaction Documents. The Company
acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to an Investor. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5 will be inadequate and
agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5, that the Investor shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and
requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required. 
  

 - 25 - 








 6. CONDITIONS TO THE COMPANY’S OBLIGATION TO SELL. 
 The obligation of the Company hereunder to issue and sell the Notes to the Investor at each Closing is subject to the satisfaction, at or before the
Closing Date, of each of the following conditions, provided that these conditions are for the Company’s sole benefit and may be waived by the Company at any time in its sole discretion by providing the Investor with prior written notice

 (i) The Investor shall have executed each of the Transaction Documents to which it is a party and delivered the
same to the Company.

and correct in all respects) as of the date when made and as of the Initial Closing Date as though made at that time (except for representations and warranties that speak as of a specific date, which shall be true and correct as of such specified
date), and such Investor shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by such Investor at or prior to the
Initial Closing Date.

 - 26 - 








 
respects) as of the Initial Closing Date (except for representations and warranties that speak as of a specific date, which shall be true and correct as of
such specified date) and the Company shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by the Transaction Documents to be performed, satisfied or complied with by the Company
at or prior to the Initial Closing Date. The Investor shall have received a certificate, executed by the Chief Executive Officer or Chief Financial Officer of the Company, dated as of the Initial Closing Date, to the foregoing effect in the form
attached hereto as Exhibit B. 
 (iv) The Collateral Agent and the Original Collateral Agent shall have executed
and delivered to such Investor the Intercreditor Agreement. 
 8. TERMINATION. In the event that the Closing shall not have occurred
with respect to the Investor on or before five (5) Business Days from the date hereof due to the Company’s or such Investor’s failure to satisfy the conditions set forth in Sections 6 and 7 above (and the nonbreaching party’s
failure to waive such unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this Agreement with respect to such breaching party at the close of business on such date without liability of any party to any other party;
provided, however, that if this Agreement is terminated pursuant to this Section 8, the Company shall remain obligated to reimburse the non-breaching Investor for the expenses described in Section 4(e) above. 
 9. MISCELLANEOUS. 
 (a) Governing
Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. 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 brought in an inconvenient forum or
that the venue of such suit, action or proceeding is improper. 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 to such party at
the address for such 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 manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY
TRANSACTION CONTEMPLATED HEREBY.  
  

 - 27 - 








 (b) Counterparts. This Agreement may be executed in two or more identical counterparts, all of
which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile signature shall be considered due execution and shall be
binding upon the signatory thereto with the same force and effect as if the signature were an original, not a facsimile signature. 
 (c)
Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement. 
 (d) Severability. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder
of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction. 
 (e)
Entire Agreement; Amendments. No provision of this Agreement may be amended other than by an instrument in writing signed by the Company, the Investor and each Other Investor, and any amendment to this Agreement made in conformity with the
provisions of this Section 9(e) shall be binding on the Company and the Investor. No provision hereof may be waived other than by an instrument in writing signed by the Company, the Investor and each Other Investor. No consideration shall be

The Company has not, directly or indirectly, made any agreements with the Investor relating to the terms or conditions of the transactions contemplated by the Transaction Documents except as set forth in the Transaction Documents. Without limiting
the foregoing, the Company confirms that, except as set forth in this Agreement, the Investor has not made any commitment or promise or has any other obligation to provide any financing to the Company or otherwise.

 (g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and

 - 29 - 








 
number of Conversion Shares issued and issuable hereunder, including by way of a Fundamental Transaction (unless the Company is in compliance with the
applicable provisions governing Fundamental Transactions set forth in the Notes). 
 (h) No Third Party Beneficiaries. This Agreement
is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person. 
 (i) Survival. Unless this Agreement is terminated under Section 8, the representations and warranties of the Company and the Investor
contained in Sections 2 and 3, and the agreements and covenants set forth in Sections 4, 5 and 9 shall survive the Closing. The Investor shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

 (j) Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and
shall execute and deliver all such other agreements, certificates, instruments and documents, as are reasonably necessary in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions
contemplated hereby. 
 (k) Indemnification. (i) In consideration of the Investor’s execution and delivery of the
Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless the Investor and each other
holder of the Securities and all of their stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those
retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and
damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the
“Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or
any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate, instrument or document
contemplated hereby or thereby or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party that is not an Affiliate of such Indemnitee (including for these purposes a derivative action brought on behalf of
the Company) and arising out of or resulting from (i) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii) any transaction
financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, or (iii) the status of such Investor or holder of the Securities as an investor in the Company. To the extent that the
foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. 

 

 - 30 - 








 (ii) Promptly after receipt by an Indemnitee under this Section 9(k) of notice of the commencement
of any action or proceeding (including any governmental action or proceeding) involving an Indemnified Liability, such Indemnitee shall, if a claim for indemnification in respect thereof is to be made against any indemnifying party under this
Section 9(k), deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnitee; provided, however, that an Indemnitee shall have the right to retain its own counsel with
the fees and expenses of not more than one counsel for such Indemnitee to be paid by the indemnifying party, if, in the reasonable opinion of the Indemnitee, the representation by such counsel of the Indemnitee and the indemnifying party would be
inappropriate due to actual or potential differing interests between such Indemnitee and any other party represented by such counsel in such proceeding. Legal counsel referred to in the immediately preceding sentence shall be selected by the
Investor holding at least a majority of the Purchased Shares. The Indemnitee shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or Indemnified Liabilities by the indemnifying party and
shall furnish to the indemnifying party all information reasonably available to the Indemnitee that relates to such action or Indemnified Liabilities. The indemnifying party shall keep the Indemnitee fully apprised at all times as to the status of
the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent, provided, however, that the indemnifying party
shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld conditioned or delayed, consent to entry of any
judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee of a release from all liability in respect to such Indemnified Liabilities
or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnitee with respect to all third parties, firms or corporations relating to the matter for which indemnification
has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnitee under this Section 9(k),
except to the extent that the indemnifying party is prejudiced in its ability to defend such action. 
 (iii) The indemnification required
by this Section 9(k) shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Liabilities are incurred. 
 (iv) The indemnity agreements contained herein shall be in addition to (x) any cause of action or similar right of the Indemnitee against the
indemnifying party or others, and (y) any liabilities the indemnifying party may be subject to pursuant to the law. 
 (l) No Strict
Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 
  

 - 31 - 








 (m) Remedies. The Investor and each holder of the Securities shall have all rights and remedies
set forth in the Transaction Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having any rights under
any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted
by law. Furthermore, the Company recognizes that in the event that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the Investor. The
Company therefore agrees that the Investor shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security. 
 (n) Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the
Transaction Documents, whenever any Investor exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Investor may
rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights. 
 (o) Payment Set Aside. To the extent that the Company makes a payment or payments to the Investor hereunder or pursuant to any of the other
Transaction Documents or the Investor enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent
or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, foreign,
state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment
had not been made or such enforcement or setoff had not occurred. 
 (p) Independent Nature of Investor’s Obligations and Rights.
