Company or the Investor, has engaged in a transaction or conduct related to the Company or the Investor, as applicable, that has resulted in (i) a SEC enforcement action, or (ii) a civil judgment or criminal conviction for fraud or
misrepresentation, or for any other offense that, if prosecuted criminally, would constitute a felony under applicable law; 

(b) if the Company or the Common Stock or any Common Shares shall cease or fail to be listed for trading or quoted on a Trading
Market (a “Trading Market Event”) if such Trading Market event continues for five consecutive days or more; 

(c) if at any time the Company has filed for and/or is subject to any bankruptcy, insolvency, reorganization or liquidation
proceedings or other proceedings for relief under any bankruptcy law or any law for the relief of debtors instituted by or against the Company or any subsidiary of the Company; 
 (d) upon the occurrence of a Fundamental Transaction; 
 (e) so long
as any Preferred Shares are outstanding, the Company (i) creates or publicly announces its intention to create a class of stock senior to the Series B Preferred Stock with respect to dividend or liquidation rights or (ii) substantially

of the holders or a majority of the Preferred Shares then outstanding; and 

  
 18 









 (f) on the Termination Date. 

3.2 Company Termination. The Company may at any time in its sole discretion terminate (a “Company
Termination”) this Agreement by providing 30 days’ advance written notice (“Termination Notice”) to Investor; provided the Company shall not have the right to terminate this Agreement if the Company is in breach
or default of this Agreement. 
 3.3 Other Termination. The Investor may terminate this Agreement by providing
three days’ advance written notice to the Company, if the Company is in breach or default of any Material Agreement which has or would reasonably be expected to have a Material Adverse Effect, and such breach or default is not cured within 20
Trading Days after notice of such breach or default is delivered to the Company. The Company or the Investor may terminate this Agreement by providing three days’ advance written notice to the other, if the other party is in material breach or
default of this Agreement or any Transaction Document or such party has committed any material anticipatory breach, and such material breach or default is not cured within 10 Trading Days after notice of such material breach or default is delivered

Shares received pursuant to the Warrant) shall be irrevocably issued as of the date delivered (or, in the case of the Warrant Shares, at the time specified in the Warrant), whether or not any Tranche Closings shall occur hereunder, subject, with
respect to the Warrant, to any termination of the Warrant that may occur pursuant to Article 8 of the Warrant as a result of the termination of this Agreement.

Authority (the “FINRA”) and (v) such consents, waivers, authorizations, order, notices, filings or registrations, the failure of which to obtain, give or make would not, individually or in the aggregate, result in a Material

applicable to the Company, including without limitation all foreign, federal, state and local laws applicable to its business, except in each of the cases referenced in clauses (i), (ii) and (iii) above as would not have a Material Adverse
Effect. 
 (m) Regulatory Permits. The Company and the Subsidiaries possess all certificates, authorizations and
permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports, except where the failure to possess such permits would not, individually or
in the aggregate, have or reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any Subsidiary has received any written notice of proceedings relating to the revocation or
modification of any Material Permit. 
 (n) Title to Assets. The Company and the Subsidiaries have good and
marketable title in fee simple to all real property owned by them that is material to the business of the Company and the Subsidiaries and good and marketable title in all personal property owned by them that is material to the business of the
Company and the Subsidiaries, in each case free and 

  
 23 









 
clear of all Liens, except for Liens as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the
Company and the Subsidiaries and Liens for the payment of federal, state or other taxes, the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease by the Company and the Subsidiaries are
held by them under valid, subsisting and enforceable leases of which the Company and the Subsidiaries are in compliance. 

(o) Patents and Trademarks. The Company has, or has rights to use, all patents, patent applications, trademarks, trademark
applications, service marks, trade names, copyrights, licenses and other similar rights that are necessary or material for use in connection with their respective businesses as described in the SEC Reports and which the failure to so have would have
a Material Adverse Effect (collectively, the “Intellectual Property Rights”). The Company is not involved in any pending litigation based on any violation or infringement of the rights of any Person. To the knowledge of the Company,
all such Intellectual Property Rights are enforceable and there is no existing infringement by another Person of any of the Intellectual Property Rights of the Company. 
 (p) Insurance. The Company is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as are prudent and customary in the businesses in
which the Company is engaged. The Company has no 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 without a significant increase in cost. 
 (q) Transactions With Affiliates and Employees.
Except as set forth in the SEC Reports, none of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or any Subsidiary (other
than 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 knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case
in excess of $120,000 other than (i) for payment of salary or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf of the Company and (iii) for other employee benefits, including stock option
agreements under any equity incentive plan of the Company. 
 (r) Sarbanes-Oxley; Internal Accounting Controls.
The Company is in material compliance with all provisions of the Sarbanes-Oxley Act of 2002 that are applicable to it. 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 Exchange Act Rules 13a-15(e) and 

  
 24 









 
15d-15(e)) for the Company and designed such disclosure controls and procedures to ensure that material information relating to the Company, including its 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 Exchange 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 date prior to the filing date of the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company
presented in its most recently filed periodic report under the Exchange 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 307(b) of Regulation S-K under the Exchange Act) or, to the Company’s knowledge, in other factors that could
materially affect the Company’s internal controls. 
 (s) Certain Fees. Except for the payment of the
Placement Agent Fee, no brokerage or finder’s fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the
transactions contemplated by this Agreement and no broker, finder, financial advisor, placement agent or investment banker has been retained in connection with the transactions contemplated by this Agreement. Except as a result of any agreements or
arrangements made by the Investor or its representatives or Affiliates, to the Company’s knowledge, Investor shall have no obligation with respect to any such fees or commissions of a type contemplated in this Section 4.1(s) that
may be due in connection with the transactions contemplated by this Agreement. 
 (t) Private Placement;
Compliance. Assuming the accuracy of Investor representations and warranties set forth in Section 4.2, no registration under the Act is required for the offer and sale of the Securities by the Company to Investor as contemplated
hereby. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of the Trading Market. 

(u) Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the
Securities, will not be or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The Company shall conduct its business in a manner so that it will not become subject to the
Investment Company Act. 
 (v) Registration Rights. Except as set forth in the SEC Reports, no Person has any
right to cause the Company to effect the registration under the Act of any securities of the Company that have not been registered. 
 (w) Listing and Maintenance Requirements. The Common Stock is registered pursuant to Section 12 of the Exchange Act, and the Company has taken no action designed to, or which to its
knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act nor, to the Company’s knowledge, is the SEC contemplating terminating such registration. Except as to the bid price deficiency
disclosed in the SEC Reports, the Company has not in the 12 months preceding the Effective Date, received notice from any 

  
 25 









 
Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements of such Trading Market
and the Company is in compliance with all such listing and maintenance requirements. 
 (x) Application of Takeover
Protections. The Company and its Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement)
or other similar anti takeover provision under the Company’s Certificate of Incorporation or the laws of its state of incorporation that is or could become applicable to Investor as a result of Investor and the Company fulfilling their
obligations or exercising their rights under the Transaction Documents, including without limitation the Company’s issuance of the Securities and Investor’s ownership of the Securities. 

(y) Disclosure. Except with respect to (i) the transactions contemplated by the Transaction Documents and
(ii) the information that will be publicly disclosed by the Company pursuant to Section 2.2(b)(i)(H) and Section 5.4, the Company confirms that neither the Company nor any other Person acting on its behalf has provided
Investor or its agents or counsel with any information that constitutes material, non-public information. The Company understands and confirms that Investor will rely on the foregoing representations and covenants in effecting transactions in
securities of the Company. All disclosure provided to Investor regarding the Company, its business and the transactions contemplated hereby, furnished by or on behalf of the Company with respect to the representations and warranties made herein are
true and correct in all material respects and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made,
not misleading. Each press release issued by the Company or any of its Subsidiaries during the twelve (12) months immediately preceding the Effective Date did not at the time of release (or, if amended or superseded by a later dated press
release issued by the Company or any of its Subsidiaries prior to the Effective Date or by a later dated SEC Report filed with or furnished to the SEC by the Company prior to the Effective Date, at the time of issuance of such later dated press
release or filing or furnishing of such SEC Report, as applicable) contain any untrue statement of a material fact or omit 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 are made, not misleading. There is no adverse material information regarding the Company that has not been publicly disclosed prior to the Effective Date. 

(z) No Integrated Offering. Neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf
has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause the offering of any of the Securities in connection herewith to be integrated with prior
offerings by the Company for purposes of the Act or which could violate any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of the applicable Trading Market. 

(aa) Financial Condition. The financial condition of the Company is as disclosed in the SEC Reports and since the most
recent of such disclosures there has been no material adverse change to the financial condition of the Company. 

  
 26 









 (bb) Tax Status. The Company and each of its Subsidiaries has made or filed
all material federal, state and foreign income and all other tax returns, reports and declarations required by any jurisdiction to which it is subject (unless and only to the extent that the Company and each of its Subsidiaries has set aside on its
books provisions reasonably adequate for the payment of all unpaid and unreported taxes) and has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on such returns, reports and
declarations, except those being contested in good faith and has set aside on its books provisions reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There are
no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim. The Company has not executed a waiver with respect to the statute of
limitations relating to the assessment or collection of any foreign, federal, state or local tax. None of the Company’s tax returns is presently being audited by any taxing authority. 

(cc) Foreign Corrupt Practices. Neither the Company, nor to the knowledge of the Company, any agent or other person acting
on behalf of the Company, has (i) directly or indirectly, used any corrupt funds for unlawful contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity, (ii) made any unlawful payment
to foreign or domestic government officials or employees or to any foreign or domestic political parties or campaigns from corporate funds, (iii) failed to disclose fully any contribution made by the Company (or made by any person acting on its
behalf of which the Company is aware) which is in violation of law, or (iv) violated in any material respect any provision of the Foreign Corrupt Practices Act of 1977, as amended. 

(dd) Acknowledgment Regarding Investor’s Purchase of Securities. The Company acknowledges and agrees that Investor is
acting solely in the capacity of arm’s length purchaser with respect to this Agreement and the transactions contemplated hereby. The Company further acknowledges that Investor is not acting as a financial advisor or fiduciary of the Company (or
in any similar capacity) with respect to this Agreement and the transactions contemplated hereby and any statement made by Investor or any of its representatives or agents in connection with this Agreement and the transactions contemplated hereby is
not advice or a recommendation and is merely incidental to Investor’s purchase of the Securities. The Company further represents to Investor that the Company’s decision to enter into this Agreement has been based solely on the independent
evaluation of the Company and its representatives. 
 (ee) Accountants. The Company’s accountants are set
forth in the SEC Reports. To the Company’s knowledge, such accountants are an independent registered public accounting firm as required by the Act. 
 (ff) No Disagreements with Accountants and Lawyers. There are no material disagreements presently existing, or reasonably anticipated by the Company to arise, between the accountants and
lawyers formerly or presently employed by the Company. 
 (gg) Registration Statements and Prospectuses.

Common Shares covered thereby, will comply as to form, in all material respects, with the requirements of the Act. 

(iv) The Prospectus and any amendment or supplement thereto, as of its date, will not contain any untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that this representation and warranty does not apply to statements in or
omissions from the Prospectus or any amendment or supplement thereto made in reliance upon and in conformity with information relating to the Investor furnished to the Company in writing by or on behalf of the Investor expressly for use therein,

understands and acknowledges that the number of Warrant Shares will increase in certain circumstances. The Company further acknowledges that its obligation to issue the Warrant Shares upon exercise of the Warrant in accordance with the Warrant is
absolute and unconditional, regardless of the dilutive effect that such issuance may have on the ownership interests of other stockholders of the Company. 

  
 28 









 (ii) Manipulation of Price. Neither the Company nor any of its Subsidiaries
has, and, to the knowledge of the Company, no Person acting on their behalf has, directly or indirectly, (i) taken any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company or any
of its Subsidiaries to facilitate the sale or resale of any of the Securities, (ii) sold, bid for, purchased, or paid any compensation for soliciting purchases of, any of the Securities, or (iii) paid or agreed to pay to any Person any

U.S. Real Property Holding Corporation. Neither the Company nor any of its Subsidiaries is, or has ever been, a U.S. real property holding corporation within the meaning of Section 897 of the Internal Revenue Code of 1986, as amended,
and the Company and each Subsidiary shall so certify upon Investor’s request. The Company shall use reasonable best efforts not to become, and not cause any of its Subsidiaries to become, a U.S. real property holding corporation so long as any
of the Securities are held by Investor; provided, however, that in the event that the Company or any of its Subsidiaries shall become a U.S. real property holding corporation, the Company shall not deliver a Tranche Notice to Investor
and no Tranche Closings shall occur without the prior written consent of Investor.

 (pp) Officers, Directors and Beneficial Owners. Schedule 4.1(pp) sets forth
the identities of all officers and directors of the Company, along with the number of shares of Common Stock beneficially owned by each such Person. 
 4.2 Representations and Warranties of Investor. Investor hereby represents and warrants to, and as applicable covenants with, the Company as follows: 

(a) Organization; Authority. Investor is an entity duly formed, validly existing and in good standing under the laws of the
jurisdiction of its organization, with the requisite power and authority to own and use its properties and assets and to carry on its business as currently conducted. Investor has the requisite company power and authority to enter into and to
consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder. The execution and delivery of the Transaction Documents to which Investor is a party and the consummation by it of the transactions
contemplated hereby and thereby have been duly authorized by all necessary company action on the part of Investor and no further consent or authorization of Investor or its members is required. Each Transaction Document to which Investor is a party
has been (or will be) duly executed by Investor, and when delivered by Investor in accordance with the terms hereof or thereof, will constitute the valid and legally binding obligation of Investor, enforceable against Investor in accordance with its
terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors’ rights and remedies. 
 (b) No Conflicts. The execution, delivery and performance of the Transaction Documents to which Investor is a party do not and will not conflict with or violate any provision of
Investor’s memorandum of association or by-laws (or similar organizational documents) as currently in effect. 
 (c)
Investor Status. At the time Investor was offered the Securities, it was, and it is: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Act or (ii) a “qualified
institutional buyer” as defined in Rule 144A(a) under the Act. 
 (d) Experience of Investor. Investor,
either alone or together with 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 the prospective investment in the Securities, and has so
evaluated the merits and risks of such investment. Investor is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment. 

(e) General Solicitation. Investor is not purchasing or acquiring the Securities as a result of any advertisement, article,
notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general solicitation or general advertisement.

 (f) No Public Sale or Distribution. Investor is acquiring the Securities for
its own account, and not as a nominee or agent, for investment purposes, and not with a view towards, or for resale in connection with, the public sale or distribution of any part thereof, all except pursuant to transactions registered under the Act
or exempt from such registration; provided, however, that the disposition of its property shall at all times be within its control. 
 (g) Acknowledgement of Private Placement. Investor understands that the offer and sale of the Securities provided for herein is being made without registration under the Act, in reliance
upon the provisions of Section 4(2) of the Act, Regulation D promulgated under the Act, and such other exemptions from the registration requirements of the Act as may be available with respect to any or all of the purchases of Securities to be
made hereunder, and that the Company is relying in part upon the truth and accuracy of, and such Investor’s compliance with, the representations, warranties, agreements, covenants, acknowledgments and understandings of such Investor set forth
herein in order to determine the availability of such exemptions and the eligibility of such Investor to acquire the Securities. 
 (h) Transfer or Resale. Investor understands that (i) the Preferred Shares, the Additional Investment Right and the Warrant have not been and are not being registered under the Act or
any state securities or “blue sky” laws and (ii) neither the Company nor any other Person is under any obligation to register the Preferred Shares, the Additional Investment Right or the Warrant under the Act or any state securities
or “blue sky” laws or to comply with the terms and conditions of any exemption thereunder with respect to the Preferred Shares, the Additional Investment Right or the Warrant. 

(i) Not an Affiliate. The Investor is not an officer, director or Affiliate of the Company. 

(j) No Governmental Review. Investor understands that no United States federal or state agency or any other government or
governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the
Securities. 
 (k) Trading Restrictions; Compliance with Securities Laws. Investor covenants and agrees that
during the period beginning on the Trading Day immediately preceding the Effective Date and ending on the Trading Day immediately following the termination of this Agreement, neither the Investor nor any of its Affiliates nor any entity managed or
controlled by the Investor will, directly or indirectly, enter into or execute or cause or assist any Person to enter into or execute any “short sale” (as such term is defined in Rule 200 of Regulation SHO, or any successor regulation,
promulgated by the SEC under the Exchange Act) of the Common Stock or trading derivative securities to the same effect. 
 The
Company acknowledges and agrees that Investor does not make or has not made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Section 4.2. 

  
 31 









 ARTICLE 5 
 OTHER AGREEMENTS OF THE PARTIES 
 5.1 Certain Transfer
Restrictions. 
 (a) The Securities constitute “restricted securities” as such term is defined in Rule
144(a)(3) and may only be disposed of in compliance with U.S. federal securities laws and applicable state securities or “Blue Sky” laws. Without limiting the generality of the foregoing, except for a transfer to an Affiliate of Investor
or a bona fide pledge of the Securities, the Securities may not be offered for sale, sold, transferred, assigned, pledged or otherwise distributed unless (i) such offer, sale, transfer, assignment, pledge or distribution is subsequently
registered under the Act, (ii) Investor shall have delivered to the Company an opinion of counsel reasonably acceptable to the Company (which may be SNR Denton), in a form generally acceptable to the Company, to the effect that such Securities
to be offered for sale, sold, transferred, assigned, pledged or otherwise distributed may be offered for sale, sold, transferred, assigned, pledged or otherwise distributed pursuant to an exemption from such registration, or (iii) such
Securities can be offered for sale, sold, transferred, assigned, pledged or otherwise distributed pursuant to Rule 144 or Rule 144A promulgated under the Act, as applicable. In furtherance of the foregoing, except as otherwise provided below and
elsewhere in this Agreement, certificates for the Preferred Shares and the Warrant shall bear the following restrictive legend: 
 THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION
NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE
COMPANY. THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES. 
 The
foregoing legend shall be removed if and when no longer required in the opinion of counsel to Investor or other holder of the Preferred Shares or Warrant in the form and substance reasonably satisfactory to the Company. Notwithstanding the foregoing
and for the avoidance of doubt, all Common Shares (including without limitation all Warrant Shares, all Additional Investment Shares, and all Placement Agent Fee Shares, if any) shall be DWAC Shares that are freely tradable by Investor, without
restrictive or other legend and without restriction on resale, and the Company shall not take any action or give instructions to any transfer agent of the Company otherwise. 

  
 32 









 (b) At the Closing, the Company shall issue irrevocable instructions to the Transfer
Agent in the form attached hereto as Exhibit C (the “Irrevocable Transfer Agent Instructions”) to issue certificates or credit shares to the applicable balance accounts at DTC, registered in the name of Investor or its
respective nominee(s), for the Securities in such amounts as specified from time to time by Investor to the Company upon delivery of the Common Shares or Preferred Shares (as the case may be). The Company represents, warrants and covenants that no
instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5.1(b) will be given by the Company to the 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 applicable, to the extent contemplated in this Agreement and the other Transaction Documents. The Company shall take all necessary action to give effect to the foregoing. The Company
acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to Investor. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5.1(b) will be
inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5.1(b), that 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. Any fees (with respect to the transfer agent, counsel to the Company or
otherwise) associated with the issuance of such opinion or the removal of any legends on any of the Securities shall be borne by the Company. 
 5.2 Furnishing of Information. As long as Investor owns Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period)
all reports required to be filed by the Company after the Effective Date pursuant to the Exchange Act. Upon the request of Investor, the Company shall deliver to Investor a written certification of a duly authorized officer as to whether it has
complied with the preceding sentence. As long as Investor owns Securities, if the Company is not required to file reports pursuant to such laws, it will prepare and furnish to Investor and make publicly available in accordance with Rule 144(c) such
information as is required for Investor to sell the Securities under Rule 144 until such time as Investor may sell all such Securities without restriction under Rule 144. The Company further covenants that it will take such further action as any
holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell Securities without registration under the Act within the limitation of the exemptions provided by Rule 144. 

5.3 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of
any security (as defined in Section 2 of the Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Act of the offer and sale of the Securities to Investor or in a manner
that could violate any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of the applicable Trading Market. 

5.4 Securities Laws Disclosure; Publicity. The Company shall (i) by 8:30 a.m., New York City time,
on the Trading Day immediately following the Effective Date, issue a press release and (ii) by 5:30 p.m., New York City time, on the fourth (4th) Trading Day immediately following the Effective Date, file a Current Report on Form 8-K describing the
transactions contemplated by, and attaching a complete copy of, the Transaction Documents. Such press release and Current Report on Form 8-K shall be reasonably acceptable to Investor. The Company and Investor shall consult with each other in
issuing any additional press releases with respect to the transactions contemplated hereby, and neither the Company nor Investor shall issue any such 

  
 33 









 
press release or otherwise make any such public statement without the prior consent of the Company, with respect to any such press release of Investor, or without the prior consent of Investor,
with respect to any such press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, Trading Market regulations or judicial process, in which case the disclosing party
shall promptly provide the other party with prior notice of such public statement or communication. The Company shall provide Investor with prior notice of any public disclosure of the name of Investor or contemplated inclusion of the name of
Investor in any filing with the SEC or any regulatory agency or Trading Market (it being hereby acknowledged and agreed by Investor that Investor’s name may be disclosed, to the extent required, in a supplemental listing application with the
Trading Market, any Current Report on Form 8-K of the Company describing the transactions contemplated by the Transaction Documents, in any Registration Statement and Prospectus covering any Common Shares, and in other reports of the Company
required to be filed by the Company under the Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof). 
 5.5 Shareholders Rights Plan. No claim will be made or enforced by the Company or, to the knowledge of the Company, any other Person that Investor is an “Acquiring Person”
under any shareholders rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that Investor could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the
Transaction Documents or under any other agreement between the Company and Investor. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act of 1940, as amended. 

5.6 Non-Public Information. The Company covenants and agrees that neither it nor any Person acting on its behalf will
provide Investor or its agents or counsel with any information that the Company believes constitutes material non-public information, unless after the Effective Date and prior thereto Investor shall have executed a written agreement regarding the
confidentiality and use of such information. The Company understands and confirms that Investor shall be relying on the foregoing covenant in effecting transactions in securities of the Company. In the event of a breach of the foregoing covenant by
the Company or any Person acting on its behalf (as determined in the reasonable good faith judgment by Investor), in addition to any other remedy provided herein or in the other Transaction Documents, the Company shall not deliver a Tranche Notice
to Investor and no Tranche Closings shall occur until such time as the Company makes a public disclosure, in the form of a press release or Current Report on Form 8-K, of such information so that such information shall no longer constitute material
non-public information. 
 5.7 Reserved. 
 5.8 Indemnification. 
 (a) Indemnification by Company.
Subject to the provisions of this Section 5.8(a), the Company will indemnify and hold Investor, its Affiliates and attorneys, and each of their directors, officers, shareholders, partners, employees, agents, and any Person who controls
Investor within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (collectively, the “Investor Parties” and each an “Investor Party”), harmless from any and all losses, liabilities,
obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of 

  
 34 









 
investigation (collectively, “Losses”) that any Investor Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties,
covenants or agreements made by the Company in this Agreement or in the other Transaction Documents, (b) any action instituted against any Investor Party, or any of them or their respective Affiliates, by any stockholder of the Company who is
not an Affiliate of an Investor Party, with respect to any of the transactions contemplated by the Transaction Documents including Investor’s acquisition of the Securities (unless such action is based upon a breach of Investor’s
representations, warranties or covenants or agreements under the Transaction Documents or any agreements or understandings Investor may have with any such stockholder or any violations by Investor of state or federal securities laws or any conduct
by Investor which constitutes fraud, gross negligence, willful misconduct or malfeasance), (c) any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement (or in a Registration Statement as amended
by any post-effective amendment thereof by the Company) or arising out of or based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and/or
(d) any untrue statement or alleged untrue statement of a material fact included in any Prospectus ( or any amendments or supplements to any Prospectus ), or arising out of or based upon any omission or alleged omission to state a material fact
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that (i) the Company shall not be obligated to indemnify any Investor Party for any Losses
finally adjudicated to have been caused-by an untrue statement of a material fact or an omission to state a material fact made in reliance upon and conformity with information furnished to the Company in writing by or on behalf of such Person
expressly for use in the Registration Statement or the Prospectus (or any amendment or supplement thereto) and (ii) the foregoing indemnity shall not inure to the benefit of any Investor Party from whom the Person asserting any Losses purchased
Securities, if a copy of the Prospectus (as then supplemented) was not sent or given by or on behalf of such Investor Party to such Person, if required by law to have been delivered, at or prior to the written confirmation of the sale of such
Securities to such person, and if delivery of the Prospectus (as then supplemented) would have cured the defect giving rise to such Losses. The parties intend that any Losses subject to indemnification under this Section 5.8(a) will be
net of insurance proceeds (which Investor agrees to use commercially reasonable efforts to recover or cause any Investor Party to recover). Accordingly, the amount which the Company is required to pay any Investor Party under this
Section 5.8(a) will be reduced by any insurance proceeds actually recovered by or on behalf of any Investor Party in reduction of the related Losses. In addition, if an Investor Party receives indemnification from the Company under this
Section 5.8(a) in respect of any Losses and subsequently receives any such insurance proceeds, then Investor will pay, or will cause such other Investor Party to pay, to the Company an amount equal to the indemnification payment received
under this Section 5.8(a) less the amount of the indemnification payment that would have been due if the insurance proceeds had been received, realized or recovered before such indemnification payment was made. However, no provision
herein regarding insurance proceeds shall delay payment by the Company to any Investor Party for any indemnified Losses. Notwithstanding anything to the contrary contained herein, the Company also agrees that neither Investor nor any such
Affiliates, partners, directors, agents, employees or controlling persons shall have any liability to the Company or any Person asserting claims on behalf of or in right of the Company solely as a result of acquiring the Securities under this
Agreement. 

  
 35 









 (b) Indemnification by Investor. Subject to the provisions of this
Section 5.8(b), the Investor will indemnify and hold the Company, its Affiliates and attorneys, and each of their directors, officers, shareholders, partners, employees, agents, and any Person who controls the Company within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act (collectively, the “Company Parties” and each a “Company Party”) harmless from all Losses that any Company Party may suffer or incur as a result
of or relating to any breach of the representations, warranties, covenants, or agreements made by the Investor in this Agreement or in other Transactional Documents. The parties intend that any Losses subject to indemnification under this
Section 5.8(b) will be net of insurance proceeds (which the Company agrees to use commercially reasonable efforts to recover or cause any Company Party to recover). Accordingly, the amount which the Investor is required to pay any
Company Party under this Section 5.8(b) will be reduced by any insurance proceeds actually recovered by or on behalf of any Company Party in reduction of the related Losses. In addition, if a Company Party receives indemnification from
the Investor under this Section 5.8(b) in respect of any Losses and subsequently receives any such insurance proceeds, then the Company will pay, or will cause such other Company Party to pay, to the Investor an amount equal to the
indemnification payment received under this Section 5.8(b) less the amount of the indemnification payment that would have been due if the insurance proceeds had been received, realized or recovered before such indemnification payment was
made. However, no provision herein regarding insurance proceeds shall delay payment by the Investor to any Company Party for any indemnified Losses. 
 (c) Procedure for Indemnification Claims. Promptly after a Person receives notice of a claim or the commencement of an action for which the Person intends to seek indemnification under this
Section 5.8, the Person will notify the indemnifying party in writing of the claim or commencement of the action, suit or proceeding; provided, however, that failure to notify the indemnifying party will not relieve the
indemnifying party from liability under this Section 5.8, except to the extent it has been materially prejudiced by the failure to give notice. The indemnifying party will be entitled to participate in the defense of any claim, action,
suit or proceeding as to which indemnification is being sought. No indemnifying party will be liable to any indemnified party under this Agreement for any settlement by such indemnified party of any action effected by such indemnified party without
the indemnifying party’s prior written consent, which shall not be unreasonably withheld or delayed. 
 5.9
Reservation of Securities. The Company shall maintain a reserve from its duly authorized shares of Common Stock for issuance pursuant to the Transaction Documents in such amount as may be required to fulfill its obligations in full under the
Transaction Documents. 
 5.10 Standstill Enforcement. The Company will use its commercially reasonable efforts to
honor and enforce the provisions of the Lock-Up Agreements with the Company’s executive officers and directors. 

5.11 Issuance of Additional Securities. The Company agrees that for the period commencing on each Tranche Notice Date and
ending on the Tranche Closing Date, neither the Company nor any of its Subsidiaries shall, without the prior written consent of the Investor, (i) directly or indirectly, issue, offer, pledge, sell, contract to sell, sell any option or contract
to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any share of Common Stock or any securities convertible into or


  
 36 









 
exercisable or exchangeable for Common Stock or file any registration statement under the Act (other than a Registration Statement on Form S-8, or any registration statement that is filed in
connection with registration rights that are outstanding on the Effective Date) with respect to any of the foregoing, or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or
indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash
or otherwise, provided that nothing in the foregoing clauses (i) and (ii) shall be construed as limiting the Company’s ability to negotiate and/or otherwise prepare to consummate a transaction following the expiration of such
restrictions, so long as such transaction is not consummated or otherwise announced (and an agreement with respect thereto is not executed) prior to the expiration of such restrictions. The provisions of this Section 5.11 shall not apply
to (A) the Securities to be issued and sold hereunder or issuable upon conversion or exercise of the Securities, (B) issuances of shares of Common Stock issuable upon conversion or exchange of currently outstanding convertible securities,
(C) granting options or other securities under the Company’s incentive compensation plans existing on the date hereof or issuances of shares of Common Stock issuable in connection with outstanding awards thereunder as of the date hereof,
(D) issuances of shares of Common Stock issuable pursuant to agreements in effect as of the date hereof or amendments related thereto, (E) issuances of shares of Common Stock in connection with strategic acquisitions, or (F) issuances
of shares of Common Stock in satisfaction of trade accounts payable and other outstanding obligations of the Company, or (G) issuances of shares of Common Stock subject to shareholder approval; provided, however, that in the case of clause
(B) above, no shares of Common Stock shall be issued as a result of an amendment to such securities after the date hereof and prior to the expiration of the restricted period. 

5.12 Registration Statement and Prospectus; Availability and Changes. The Company covenants that it will comply with the
matters set forth in Section 4.1(gg) without giving effect to any exceptions contained in or contemplated by this Agreement. The Company will make available to Investor upon request, and thereafter from time to time will furnish Investor, as
many copies of any Prospectus (or of the Prospectus as amended or supplemented if the Company shall have made any amendments or supplements thereto after the effective date of the applicable Registration Statement) as Investor may request for the
purposes contemplated by the Act; and in case Investor is required to deliver a prospectus after the nine-month period referred to in Section 10(a)(3) of the Act in connection with the sale of the Common Shares, or after the time a
post-effective amendment to the applicable Registration Statement is required pursuant to Item 512(a) of Regulation S-K under the Act, the Company will prepare, at its expense, promptly upon request such amendment or amendments to the
Registration Statement and the Prospectus as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Act or Item 512(a) of Regulation S-K under the Act, as the case may be. The Company will advise Investor
promptly of the happening of any event within the time during which a Prospectus is required to be delivered by Investor under the Act which, in the good faith judgment of the Company, following consultation with its independent legal counsel, would
require the making of any change in the Prospectus then being used so that the Prospectus would not include an untrue statement of material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the
circumstances under which they are made, not misleading, and to advise Investor promptly if, during such period, in the good faith judgment of the Company, following consultation with its independent legal counsel, it shall become necessary to amend
or supplement 

  
 37 









 
any Prospectus to cause such Prospectus to comply with the requirements of the Act, and in each case, during such time, to prepare and furnish, at the Company’s expense, to Investor promptly
such amendments or supplements to such Prospectus as may be necessary to reflect any such change or to effect such compliance. The Company shall take such other action as requested by Investor with respect to compliance with any applicable
securities laws (including, without limitation, “Blue-Sky” laws) in connection with the offer, sale and resale of the Common Shares or the Securities. Each Prospectus (including all prospectus supplements) shall be in the form and
substance satisfactory to Investor. 
 5.13 Required Approval. No transactions contemplated under this Agreement
or the Transaction Documents shall be consummated for an amount that would require approval by the Company’s stockholders under any approval provisions, rules or regulations of any Trading Market applicable to the Company, unless and until such
approval is obtained. Company shall use its reasonable best efforts to obtain any required approval as soon as possible. 

5.14 Activity Restrictions. For so long as Investor or any of its Affiliates holds any Securities, neither Investor nor any
Affiliate will: (i) vote any shares of Common Stock owned or controlled by it, solicit any proxies, or seek to advise or influence any Person with respect to any voting securities of the Company; (ii) engage or participate in any actions,
plans or proposals which relate to or would result in (a) acquiring additional securities of the Company, alone or together with any other Person, which would result in beneficially owning or controlling, or being deemed to beneficially own or
control, more than 9.99% of the total outstanding Common Stock or other voting securities of the Company, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving Company or any of its subsidiaries,
(c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries, (d) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term
of directors or to fill any existing vacancies on the board, (e) any material change in the present capitalization or dividend policy of the Company, (f) any other material change in the Company’s business or corporate structure,
including but not limited to, if the Company is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the Investment Company Act of 1940,
(g) changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any Person, (h) causing a class of securities of the Company to be
delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Company becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Act, or (j) any action, intention, plan or arrangement similar to any of those enumerated above; or (iii) request the Company or its directors, officers, employees,
agents or representatives to amend or waive any provision of this Section 5.14. 
 5.15 Investor
Information. The Company shall notify Investor in writing of the information that the Company requires from Investor with respect to the Registration Statement and/or Prospectus in connection with the transactions contemplated by this Agreement
and Investor shall, as soon as practicable after being so notified, furnish to the Company such information regarding itself, the Securities held by it and the intended method of disposition of the Securities held by it, as shall be reasonably
required to effect and/or maintain the effectiveness of the registration of such Securities.

waiver is sought. 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 either party to exercise any right hereunder in any manner impair the exercise of any such right. 

  
 39 









 6.4 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. 
 6.5 Successors

consent of Investor, which consent will not be unreasonably withheld or delayed. Investor may not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Company, which consent shall not be unreasonably

including a redemption by offset, exchange, and cancellation with the Company as set forth in the Certificate of Designations. 

6.6 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, except as otherwise expressly set forth in Section 5.8 hereof. 

6.7 Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction
Documents 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 that would require or permit the application of the laws of any other
jurisdiction. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (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. 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 (including with respect to the
enforcement of any of the Transaction Documents), 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 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 manner permitted by law. The parties hereby waive all rights to a trial by jury. If either party shall commence an action or proceeding to

 40 









 6.8 Survival. The representations, warranties, covenants and agreements of the
Company and the Investor contained in this Agreement shall survive the Closing and the delivery and/or exercise of the Securities, as applicable, until the termination of this Agreement; provided, however, that (i) the provisions of
Section 3.4 (Effect of Termination), Article 4 (Representations and Warranties), Section 5.8 (Indemnification), this Article 6 (Miscellaneous) and all fees and expenses provisions contained in this Agreement (including,
without limitation, provisions relating to the issuance of the Placement Agent Fee Shares and the payment of the fees and expenses in accordance with Section 6.1) shall remain in full force and effect indefinitely notwithstanding such
termination, and, (ii) so long as the Investor owns any Securities, the covenants and agreements of the Company contained in Article 5 (Other Agreements of the Parties) shall remain in full force and effect notwithstanding such termination.
Notwithstanding anything to the contrary herein, any Securities issued prior to any such termination shall remain outstanding thereafter and unaffected thereby and the Company shall comply with all terms and conditions thereof (including, without
limitation, the issuance of the Warrant Shares upon the due exercise of the Warrant and the issuance of the Additional Investment Shares upon the due exercise of the Additional Investment Right) shall not be affected by such termination. 

6.9 Execution. 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. In the event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable
document format (.pdf) file of an executed signature page, such signature page 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 signature
page were an original thereof. 
 6.10 Severability. 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. 

6.11 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or
destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs
associated with the issuance of such replacement Securities. 
 6.12 Remedies. In addition to being entitled to
exercise all rights provided herein or granted by law, including recovery of damages, each of Investor and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of obligations under the Transaction Documents and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be
adequate, the necessity of showing economic loss and without any bond or other security being required. Neither the Company nor Investor shall be liable for special, indirect, consequential or punitive damages suffered or alleged to be suffered by
the other party or any third party, whether arising from or related to the Transaction Documents or otherwise. 

  
 41 









 6.13 Payment Set Aside. To the extent that the Company makes a payment or
payments to Investor pursuant to any Transaction Document or Investor enforces or exercises its rights 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, 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. 
 6.14 Partial Damages. If the
Company’s obligations to pay any partial damages or other amounts owing under the Transaction Documents is a continuing obligation of the Company, then such obligation shall not terminate until all unpaid partial damages and other amounts have
been paid notwithstanding the fact that the instrument or security pursuant to which such partial damages or other amounts are due and payable shall have been canceled. 
 6.15 Time of the Essence. Time is of the essence with respect to all provisions of this Agreement that specify a time for performance. 

6.16 Construction. The parties agree that each of them and/or their respective counsel has reviewed and had an opportunity
to revise the Transaction Documents 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 the Transaction Documents or any
amendments hereto. 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. Each and every reference to share
prices, shares of Common Stock and any other numbers in this Agreement that relate to the Common Stock (excluding percentages) shall be automatically appropriately adjusted for stock splits, stock combinations and other similar transactions that
occur with respect to the Common Stock after the date of this Agreement. 
 6.17 Entire Agreement. The Transaction
Documents contain the entire agreement and understanding of the parties, and supersede all prior and contemporaneous agreements, term sheets, letters, discussions, communications and understandings, both oral and written, which the parties
acknowledge have been merged into the Transaction Documents. Neither party has relied upon any agreement, assurance, promise, understanding or representation not expressly set forth in the Transaction Documents and each party agrees that it may only
rely on the agreements, assurances, promises, understandings and representations set forth therein; provided, however, Investor shall be entitled to the protections with respect to, and to rely on statements contained in, the
Registration Statement and Prospectus in accordance with federal and state securities laws. 
 6.18 Further
Assurances. From and after the Effective Date, upon the request of Investor or the Company, each of the Company and Investor shall execute and deliver such instruments, documents and other writings as may be reasonably necessary or desirable to
confirm and carry out and to effectuate fully the intent and purposes of this Agreement.

of any Tranche Notice delivered by the Company from time to time, this Warrant shall automatically be exercised for that number of shares of Common Stock as set forth below. 







 This Warrant is issued pursuant to the Securities Purchase Agreement, dated as of
December 22, 2011, and among the Company and Socius CG II, Ltd. (the “Purchase Agreement”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in this Warrant or, if not
defined in this Warrant, in the Purchase Agreement. 
 This Warrant shall vest and become automatically exercisable in tranches
(each, a “Warrant Tranche”) upon each delivery of a Tranche Notice under the Purchase Agreement. Each Tranche Notice will obligate the Holder to exercise a portion of this Warrant and purchase that number of shares of Common Stock
that may be purchased by payment of an Aggregate Exercise Price equal to Thirty-five Percent (35%) of the Tranche Purchase Price specified in such Tranche Notice divided by the Exercise Price; provided, however, that the aggregate
number of Warrant Shares issued upon exercise of this Warrant shall not exceed the Warrant Share Amount. Attached to this Warrant is a schedule (the “Warrant Tranche Schedule”) that shall set forth the issuance date, the number of
Warrant Shares, and the Exercise Price for each Warrant Tranche. The Warrant Tranche Schedule shall be updated by the Company subject to approval by the Holder, with an updated copy provided to the Holder, promptly following each exercise of this
Warrant and any dispute with respect to the foregoing shall be resolved in accordance with ARTICLE 11. 
 In no event
shall the Company be permitted to deliver a Tranche Notice if the number of freely tradable (without restriction) registered shares underlying this Warrant is insufficient to cover the portion of the Warrant that will vest and become exercisable in
connection with such Tranche Notice. 
 ARTICLE 1 
 EXERCISE OF WARRANT; ADJUSTMENT TO EXERCISE 
 PRICE AND NUMBER OF SHARES.

 1.1 Mechanics of Exercise. 
 (a) Subject to the terms and conditions hereof, this Warrant shall be automatically exercised by the Holder on each Tranche Notice Date, in whole or in part. Within one (1) Trading Day following such
Tranche Notice Date and automatic exercise, Holder shall (i) deliver, for record keeping purposes, a written notice to the Company, in the form attached hereto as Appendix 1 (the “Exercise Notice”)(it being understood and
agreed that the delivery of an Exercise Notice shall not be a condition to the automatic exercise of this Warrant), and (ii) pay to the Company an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares as to
which this Warrant is being exercised (the “Aggregate Exercise Price”), which payment shall be made, at the option of the Holder, in cash or by wire transfer of immediately available funds, or by the issuance and delivery of a
recourse promissory note substantially in the form attached as Exhibit G to the Purchase Agreement (each, a “Recourse Note”). The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder.
Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original Warrant certificate and issuance of a new Warrant certificate evidencing the right to
purchase the remaining number of Warrant Shares. 

  
 2 








 (b) On the Trading Day immediately following the Exercise Delivery Date, the Company shall
transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Delivery Documents to the Holder and an electronic copy of its share issuance instructions to the Holder and the Company’s transfer agent (the “Transfer
Agent”) (which such electronic transmissions shall comply with the notice provisions of Section 6.2 of the Purchase Agreement), and shall instruct, authorize and cause the Transfer Agent to credit an aggregate number of freely tradable
Warrant Shares pursuant to such exercise to the Holder’s or its designee’s balance account with The Depository Trust Company (DTC) through the Fast Automated Securities Transfer (FAST) Program through its Deposit/Withdrawal at Custodian
(DWAC) system, with such credit to occur no later than 12:00 p.m. New York City time on the third Trading Day following the Exercise Delivery Date, time being of the essence; provided, however, that if the Warrant Shares are not
credited as DWAC Shares by 5:00 p.m. New York City time on the Trading Day following the Exercise Delivery Date, then the Tranche Closing Date applicable to the Exercise Notice shall be extended by one (1) Trading Day for each Trading Day that
timely credit of DWAC Shares is not made. Upon automatic exercise of any portion of this Warrant, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has
been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificate(s) evidencing the Warrant Shares (as the case may be). 

(c) If this Warrant is submitted in connection with any exercise pursuant to this Section 1.1 and the number of Warrant
Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then the Company, upon the request of the Holder, shall as soon as practicable and in no event later than three
(3) Trading Days after any exercise and return of the previously issued Warrant, at its own expense issue a new Warrant representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under this
Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall
be rounded up to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. 

1.2 Exercise Price. For purposes of this Warrant, “Exercise Price” means, subject to adjustment as provided
herein: (i) until the first Tranche Notice Date, the price per Warrant Share as set forth on the face of this Warrant, and (ii) on and after the first Tranche Notice Date and each subsequent Tranche Notice Date, an amount per Warrant Share
equal to the Closing Bid Price of a share of Common Stock on the most recently completed Trading Day prior to the time that the Tranche Notice was deemed delivered for the applicable Tranche Notice Date; provided, however, that the
exercise price per Warrant Share must equal or exceed the greater of (1) the Book Value (as defined in the Securities Purchase Agreement) of the Common Stock, and (2) the Closing Bid Price of the Common Stock, in each case, on the most
recently completed Trading Day prior to the Effective Date. 

  
 3 








 1.3 Number of Shares. At each time of delivery of a Tranche Notice, the number of
Warrant Shares underlying this Warrant shall be adjusted such that after such adjustment (and taking account of the adjustment to the Exercise Price in accordance with Section 1.2 above) the aggregate Exercise Price payable hereunder for
the adjusted number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustments (in each case, without regard to any limitations on exercise contained herein). Immediately following such
adjustment, the number of Warrant Shares underlying the applicable Warrant Tranche shall vest and become exercisable and such number of Warrant Shares in such Warrant Tranche shall be a number of shares equal to the Tranche Purchase Price set forth
in the applicable Tranche Notice multiplied by 35%, with the resulting product divided by the Exercise Price as adjusted in accordance with Section 1.2 above to give effect to the applicable Tranche Notice (in respect of any Warrant
Tranche, the “Warrant Tranche Shares”). For illustrative purposes only, assume that the Warrant is initially exercisable for 3,500,000 Warrant Shares at an initial Exercise Price of $0.50 (for a total aggregate Exercise Price of
$1,750,000). The Company then delivers a Tranche Notice with a Tranche Purchase Price of $1,000,000 and the Closing Bid Price of a share of Common Stock on the most recently completed Trading Day prior to the time that the Tranche Notice was deemed
delivered is $0.25. Immediately prior to the automatic exercise of the Warrant, the Exercise Price will be adjusted to $0.25 and the Warrant Shares will be increased to 7,000,000 (to maintain the pre-adjustment aggregate Exercise Price of
$1,750,000). The number of Warrant Shares underlying the Warrant that become vested and automatically exercised shall be $1,000,000 x 35% = $350,000 divided by $0.25 = 1,400,000 Warrant Shares. After such automatic exercise, the Warrant will be
exercisable for 5,600,000 Warrant Shares at an Exercise Price of $0.25 (with an aggregate Exercise Price of $1,400,000 ($1,750,000 minus $350,000)). The Company then delivers a second Tranche Notice with a Tranche Purchase Price of $2,000,000 and
the Closing Bid Price of a share of Common Stock on the most recently completed Trading Day prior to the time that the Tranche Notice was deemed delivered is $0.35. Immediately prior to the automatic exercise of the Warrant, the Exercise Price will
be adjusted to $0.35 and the Warrant Shares will be decreased to 4,000,000 (to maintain the pre-adjustment aggregate Exercise Price of $1,400,000). The number of Warrant Shares underlying the Warrant that become vested and automatically exercised
shall be $2,000,000 x 35% = $700,000 divided by $0.35 = 2,000,000 Warrant Shares. After such automatic exercise, the Warrant will be exercisable for 2,000,000 Warrant Shares at an Exercise Price of $0.35 (with an aggregate Exercise Price of $700,000
($1,400,000 minus $700,000)). For clarification purposes, both the Exercise Price and number of Warrant Shares underlying this Warrant and each Warrant Tranche shall each be deemed to be adjusted in accordance with Section 1.2 above and
this Section 1.3 immediately prior to the determination of the number of Warrant Tranche Shares and the automatic vesting and exercise of this Warrant in connection therewith. 

For clarification purposes, if a portion of the Warrant has been automatically exercised pursuant to the terms of this Warrant but the
related Tranche Closing fails to occur, the Warrant Share Amount shall be increased by the number of Warrant Shares that were issued in connection with such automatic exercise. Notwithstanding anything to the contrary herein, until the Purchase
Agreement has been terminated in accordance with its terms, the number of Warrant Shares underlying this Warrant shall be adjusted, as necessary, to permit the issuance of all Warrant Tranche Shares in connection with any Warrant Tranche.

 1.4 Reserved.

 1.5 Company’s Failure to Timely Deliver Securities. If the Company shall fail
for any reason or for no reason to credit, by 5:00 p.m. New York City time on the Trading Day following the Exercise Delivery Date, the Holder’s balance account with DTC for such number of Warrant Shares to which the Holder is entitled upon the
Holder’s automatic exercise of this Warrant (as the case may be), then, in addition to all other remedies available to the Holder, the Company shall pay in cash to the Holder on each day that the issuance of such Warrant Shares is not timely
effected an amount equal to 1.5% of the product of (A) the sum of the number of Warrant Shares not issued to the Holder on a timely basis and to which the Holder is entitled and (B) the Closing Sale Price of the shares of Common Stock on
the Trading Day immediately preceding the last possible date which the Company could have issued such Warrant Shares to the Holder without violating Section 1.1. In addition to the foregoing, if after the Company’s receipt of the
applicable Exercise Delivery Documents the Company shall fail to timely credit the Holder’s balance account with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s automatic exercise hereunder, and the
Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Warrant Shares issuable upon such exercise that the Holder anticipated receiving from the Company (a
“Buy-In”), then the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to credit such Holder’s balance account with DTC for the number of
Warrant Shares to which the Holder is entitled upon the Holder’s exercise hereunder and to issue such Warrant Shares shall terminate, or (ii) promptly honor its obligation to credit such Holder’s (or its designee’s) balance
account with DTC for the number of Warrant Shares to which the Holder is entitled upon the Holder’s exercise hereunder and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such
number of shares of Common Stock sold by Holder in satisfaction of its obligations, times (B) the Closing Bid Price on the date of exercise. 
 1.6 Exercise Limitations. 
 (a) Notwithstanding any other provisions herein
or in the Purchase Agreement to the contrary, at no time shall the delivery of a Tranche Notice be effective to the extent that the number of Warrant Shares to be received pursuant to the automatic exercise of this Warrant, aggregated with all other
shares of Common Stock and other voting securities then owned or deemed beneficially owned by the Holder and its Affiliates, would result in the Holder together with its Affiliates beneficially owning or being deemed the beneficial owner of more
than 9.99% of the Common Stock, with such ownership percentage determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder (the “Maximum Percentage”). The provisions of
this Section 1.6(a) shall be implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum
Percentage beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage limitation. The limitations contained in this paragraph shall apply to a
successor Holder of this Warrant. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of holders of a majority of its Common Stock. 

  
 5 








 (b) In addition to the restrictions set forth in Section 1.6(a) above and
notwithstanding any provisions of the Purchase Agreement to the contrary, at no time may the Company deliver a Tranche Notice if the number of Common Shares to be issued upon the automatic exercise of this Warrant (together with all other shares of
Common Stock issued pursuant to previous Tranche Notices) would exceed the aggregate number of shares of Common Stock which the Company may issue without breaching the Company’s obligations under the rules or regulations of the applicable
Trading Market, except that such limitation shall not apply in the event that the Company obtains the approval of its stockholders as required by the applicable rules of the applicable Trading Market for issuances of Common Shares in excess of such
amount. 
 1.7 Restrictions. For so long as Holder holds this Warrant or any Warrant Shares, Holder will not:
(i) vote any shares of Common Stock owned or controlled by it, solicit any proxies, or seek to advise or influence any Person with respect to any voting securities of the Company; (ii) engage or participate in any actions, plans or
proposals which relate to or would result in (a) acquiring additional securities of the Company, alone or together with any other Person, which would result in beneficially owning or controlling, or being deemed to beneficially own or control,
more than 9.99% of the total outstanding Common Stock or other voting securities of the Company, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving Company or any of its subsidiaries,
(c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries, (d) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term
of directors or to fill any existing vacancies on the board, (e) any material change in the present capitalization or dividend policy of the Company, (f) any other material change in the Company’s business or corporate structure,
including but not limited to, if the Company is a registered closed-end investment company, any plans or proposals to make any changes in its investment policy for which a vote is required by Section 13 of the Investment Company Act of 1940,
(g) changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any Person, (h) causing a class of securities of the Company to be
delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Company becoming eligible for
termination of registration pursuant to Section 12(g)(4) of the Act, or (j) any action, intention, plan or arrangement similar to any of those enumerated above; or (iii) request the Company or its directors, officers, employees,
agents or representatives to amend or waive any provision of this Section 1.7. 
 1.8 Disputes. In the case
of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance
with ARTICLE 11. 
 1.9 Insufficient Authorized Shares. If at any time while this Warrant (or any portion thereof)
remains outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common Stock equal
to One Hundred Percent (100%) of the number of shares of Common Stock as shall from time to time be necessary to effect the 

  
 6 








 
exercise in full of any unexercised portion of this Warrant (the “Required Reserve Amount”) (an “Authorized Share Failure”), then the Company shall immediately
take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the unexercised portion of the Warrant then outstanding. Without
limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than ninety (90) days after the occurrence of such Authorized Share Failure, the
Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its
best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. 

ARTICLE 2 

ADJUSTMENT UPON SUBDIVISION OR COMBINATION OF COMMON STOCK 
 If the Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a
greater number of shares, the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares then subject hereto will be proportionately increased. If the Company at any time on or
after the Issuance Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination
will be proportionately increased and the number of Warrant Shares then subject hereto will be proportionately decreased. Any adjustment under this ARTICLE 2 shall become effective at the close of business on the date the subdivision or combination
becomes effective. 
 ARTICLE 3 
 FUNDAMENTAL TRANSACTIONS 
 3.1 Purchase Rights. In addition to any
adjustments pursuant to ARTICLE 2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares
of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the
number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) immediately before the date on which a record is taken for the grant, issuance or sale of such
Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights; provided, however, to the extent that the
Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such
shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the
Maximum Percentage. 

  
 7 








 3.2 Fundamental Transactions. The Company shall not enter into or be party to a
Fundamental Transaction unless the Successor Entity assumes in writing all of the obligations set forth in this Section 3 pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the
Holder prior to such Fundamental Transaction. Immediately prior to the consummation of a Fundamental Transaction, and notwithstanding anything contained herein to the contrary, this Warrant and the number of Warrant Shares underlying this Warrant
shall fully vest and the Company, or the Successor Entity if the Company shall for any reason fail to do so (but without reducing the Company’s obligations hereunder), shall automatically purchase this Warrant from the Holder on the date of
consummation of such Fundamental Transaction by paying to the Holder cash in an amount equal to the Black Scholes Value; provided, however, that this Section 3.2 shall not apply if the Company is the survivng entity in any
Fundamental Transaction. 
 ARTICLE 4 
 NONCIRCUMVENTION 
 The Company hereby covenants and agrees that the Company
will not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. Without
limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions
as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as the Warrant (or any portion thereof)
is outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the Warrant, 100% of the number of shares of Common Stock as shall
from time to time be necessary to effect the exercise of the unexercised portion of the Warrant then outstanding (without regard to any limitations on exercise). 
 ARTICLE 5 
 WARRANT HOLDER NOT DEEMED A STOCKHOLDER 

Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall
not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the
Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger,
conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder 

  
 8 








 
of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any
liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this ARTICLE
5, the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders. 

ARTICLE 6 

REISSUANCE OF WARRANTS 
 6.1 Transfer of Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the
Holder a new Warrant, registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less then the total number of Warrant Shares then underlying this Warrant is being
transferred, a new Warrant to the Holder representing the right to purchase the number of Warrant Shares not being transferred. Notwithstanding the foregoing, no transfer shall relieve the Holder of its obligations to exercise this Warrant if the
transferee fails to exercise this Warrant in accordance with its terms. 
 6.2 Lost, Stolen or Mutilated Warrant. Upon
receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company
in customary form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant representing the right to purchase the Warrant Shares then underlying this Warrant.

 6.3 Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the
principal office of the Company, for a new Warrant or Warrants representing in the aggregate the right to purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion
of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no Warrants for fractional shares of Common Stock shall be given. 
 6.4 Issuance of New Warrants. Whenever the Company is required to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant,
(ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 6.1 or
Section 6.3, the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares
then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions as this Warrant.

unless otherwise provided herein, such notice shall be given in accordance with Section 6.2 of the Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Warrant, including in
reasonable detail a description of such action and the reason therefore. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) as soon as practicable upon any adjustment of the Exercise Price,
setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or
distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property to holders of shares of Common Stock as
such or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation. In each case such information shall be made known to the public prior to or in conjunction with such notice being provided to
the Holder. 
 ARTICLE 8 
 AMENDMENT AND WAIVER; TERMINATION 
 Except as otherwise provided herein,
the provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder; provided that
except as provided herein, no such action may increase the exercise price of the Warrant or decrease the number of shares or class of stock obtainable upon exercise of the Warrant without the written consent of each Holder. No such amendment shall
be effective to the extent that it applies to less than all of the holders of the Warrants then outstanding. 
 This Warrant shall terminate at 11:59 p.m. New York City time on the earlier of (i) the second (2nd) anniversary of the Issuance Date, or (ii) the date that the Securities Purchase Agreement terminates.
Notwithstanding any such termination, (x) any Warrant Shares obtained by the Holder prior to termination shall remain outstanding and all rights of the Holder with respect thereto as set forth in this Warrant shall survive for the period of the
applicable statutes of limitation, and (y) the provisions of Article 1.7 (Restrictions), Article 9 (Governing Law), and Article 13 (Definitions) shall survive any such termination and shall survive for the period of the applicable statutes of
limitation. 
 ARTICLE 9 
 GOVERNING LAW 
 This Warrant shall be governed by and construed and
enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.

 ARTICLE 10 
 CONSTRUCTION; HEADINGS 
 This Warrant shall be deemed to be jointly drafted
by the Company and the Holder and shall not be construed against any person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. 

ARTICLE 11 

DISPUTE RESOLUTION 
 In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations
via facsimile within two (2) Trading Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise
Price or the Warrant Shares within three (3) Trading Days of such disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Trading Days submit via facsimile (a) the
disputed determination of the Exercise Price or arithmetic calculation to an independent, reputable investment bank or independent registered public accounting firm selected by Holder subject to Company’s approval, which may not be unreasonably
withheld or delayed, or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent registered public accounting firm. The Company shall cause at its expense the investment bank or the accountant, as the case
may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than three (3) Trading Days from the time it receives the disputed determinations or calculations. Such investment bank’s
or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error. 
 ARTICLE 12 
 REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF

 The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this
Warrant, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this
Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any
such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other
security being required.

 4. Protective Provision. So long as any shares of Series B Preferred Stock are

a. A “Deemed Liquidation Event” shall mean: (i) a merger or consolidation in which the Corporation is a constituent
party or a subsidiary of the Corporation is a constituent party and the Corporation issues shares of its capital stock pursuant to such merger or consolidation, except any such merger or consolidation involving the Corporation or a subsidiary in

substantially all of the assets of the Corporation and its subsidiaries taken as a whole are held by such subsidiary or subsidiaries, except where such sale, lease, transfer, exclusive license or other disposition is to a wholly owned subsidiary of
the Corporation. 
 b. The Corporation shall not have the power to effect a Deemed Liquidation Event referred to in
Section 4(a) unless the agreement or plan of merger or consolidation for such transaction provides that the consideration payable to the stockholders of the Corporation shall be allocated among the holders of capital stock of the
Corporation in accordance with Section 5. 
 5. Liquidation. 

a. Upon any liquidation, dissolution or winding up of the Corporation, whether voluntary or involuntary, after payment or provision for
payment of debts and other liabilities of the Corporation, before any distribution or payment shall be made to the holders of any Junior Shares by reason of their ownership thereof, but after any distribution or payment to be made to the holders of
any Senior Shares and simultaneous with any distribution or payment to be made to the holders of any pari passu shares, the Holders of Series B Preferred Stock shall be entitled to be paid out of the assets of the Corporation available for
distribution to its stockholders an amount with respect to each share of Series B Preferred Stock equal to $10,000.00 (as adjusted for any stock dividends, combinations, splits or the like with respect to such shares), plus any


  
 3 








 
accrued or declared but unpaid Dividends thereon (collectively, the “Series B Liquidation Value”). If, upon any liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, and after any distribution or payment to be made to the holders of any Senior Shares, the amounts payable with respect to the shares of Series B Preferred Stock are not paid in full, the holders of shares of Series B
Preferred Stock shall share equally and ratably in any distribution of assets of the Corporation in proportion to the liquidation preference and an amount equal to all accumulated and unpaid Dividends, if any, to which each such holder is entitled.

 b. After payment has been made to the Holders of the Series B Preferred Stock of the full amount of the Series B Liquidation
Value, any remaining assets of the Corporation shall be distributed among the holders of Junior Shares in accordance with the Corporation’s Articles of Incorporation. 
 c. If, upon any liquidation, dissolution or winding up of the Corporation, the assets of the Corporation shall be insufficient to make payment in full to all Holders, then such assets shall be distributed
among the Holders at the time outstanding, ratably in proportion to the full amounts to which they would otherwise be respectively entitled. 
 d. The value of any securities to be delivered to the Holders pursuant to this Section 5 shall be determined as follows: 
 (i) If listed on a national securities exchange, the value shall be deemed to be the average of the closing prices of the securities on such exchange over the thirty day period ending three days prior to
the date of the Deemed Liqudation Event (the “Deemed Liquidity Date”); 
 (ii) If actively traded over the
counter, the value shall be deemed to be the average of the closing bid prices over the thirty day period ending three days prior to the Deemed Liquidity Date; and 
 (iii) If there is no active public market, the value shall be the fair market value thereof as determined jointly in good faith by the Holder and the Corporation’s board of directors. 

6. Redemption. 
 a. Corporation’s Redemption Option. At any time after the initial Issuance Date, the Corporation shall have the right, at the Corporation’s option, to redeem all (but not less than all)
of the shares of Series B Preferred Stock, at a price per share of Series B Preferred Stock equal to the Series B Liquidation Value, which redemption may be effectuated in exchange for all (but not less than all) secured promissory notes (the
“Promissory Notes”) issued by the Holder to the Corporation as set forth further below. 
 b. Mandatory
Redemption. If the Corporation (a) enters into an agreement to or otherwise adopts or approves a plan or arrangement with respect to liquidation, dissolution or winding-up of its business and affairs, or (b) effects any Deemed
Liquidation Event, the Corporation shall redeem the Series B Preferred Stock at the price set forth in Section 6(a) and in the manner set forth in Section 6(c) and Section 6(d) below. 

  
 4 








 c. Mechanics of Redemption. Subject to Section 6(d) below, if the
Corporation elects to redeem or is required to redeem the Holders’ Series B Preferred Stock then outstanding, it shall deliver written notice thereof via facsimile and overnight courier (“Notice of Redemption”) to each Holder,
which Notice of Redemption shall indicate (A) the number of shares of Series B Preferred Stock that the Corporation is electing to redeem or is required to redeem (which shall not be less than all of the outstanding shares of Series B Preferred
Stock), (B) the redemption price calculated under Section 6(a) above, and (C) the manner and the place designated for the surrender of the certificate or certificates representing the shares to be redeemed. The aggregate price
of the Preferred Stock to be redeemed at the redemption price calculated under Section 6(a) above is referred to herein as the “Corporation Redemption Price”. 

d. Payment of Redemption Price. Upon receipt by any Holder of a Notice of Redemption, such Holder shall promptly submit to the
Corporation such Holder’s Series B Preferred Stock certificates in the manner and at the place designated in the Notice of Redemption. Upon receipt of such Holder’s Series B Preferred Stock certificates, the Corporation shall pay the
Corporation Redemption Price at the option of the Company either (i) in cash, or (ii) by offset against and in cancellation of all amounts due and owing under all outstanding promissory notes payable from Holder to the Corporation that
were issued by Holder in connection with the exercise of warrants or additional investment rights by such Holder (the “Promissory Notes”) (it being understood that following such offset and cancellation, no further amounts are or
shall be due or payable with respect to such shares of Series B Preferred Stock or such Promissory Notes and all of such shares of Series B Preferred Stock and Promissory Notes shall no longer be outstanding). For clarification purposes, in the
event that the Corporation elects to pay the Corporation Redemption Price in cash under clause (i) above, it shall so notify Holder and Holder may thereafter elect to instead effect such redemption in exchange for Promissory Notes in accordance
with clause (ii) above, in which case clause (ii) above shall apply. 
 Notwithstanding the foregoing, if, in the event of a mandatory
redemption under Section 6(b) above, the funds of the Corporation legally available for redemption of shares of Series B Preferred Stock on any redemption date are insufficient to redeem the total number of shares of Series B Preferred
Stock to be redeemed on such date, those funds that are legally available will be used to redeem shares from the Holders ratably in proportion to the aggregate Corporation Redemption Prices that would be payable to each Holder if all shares required
to be redeemed were being redeemed. If any Holder holds more than one series of Preferred Stock, the same proportion of each series of shares held by such holder will be redeemed. The shares of Series B Preferred Stock not redeemed shall remain
outstanding and be entitled to all the rights and preferences provided herein. If any time thereafter additional funds become legally available for the redemption, such funds will immediately be used to redeem the balance of the shares which the
Corporation has become obliged to redeem on any redemption date but which it has not redeemed. In the event that the limitations contained in this paragraph apply with respect to any mandatory redemption under Section 6(b) above and the
Company determines, or is required by the Holder, to redeem the shares of Series B Preferred Stock in accordance with clause (ii) of Section 6(d) above, then the percentage of the Series B Preferred Stock then being redeemed as a
result of the 

  
 5 








 
application of the limitations of this paragraph (in relation to all then outstanding shares Series B Preferred Stock) shall be redeemed in exchange for and in cancellation of the same percentage
of then outstanding Promissory Notes (in relation to all then outstanding Promissory Notes) and from and after such redemption, no amounts shall be due and owning as to such shares of Series B Preferred Stock or such Promissory Notes then redeemed
and exchanged and such shares of Series B Preferred Stock and such Promissory Notes then redeemed and exchanged shall no longer be outstanding. 
 7. Transferability. 
 a. The Series B Preferred Stock constitutes
“restricted securities” as such term is defined in Rule 144(a)(3) under the Act and may only be disposed of in compliance with U.S. federal securities laws and applicable state securities or “blue sky” laws. Without limiting the
generality of the foregoing, the Series B Preferred Stock may not be offered for sale, sold, transferred, assigned, pledged or otherwise distributed unless (A) subsequently registered thereunder, (B) Holder shall have delivered to the
Corporation an opinion of counsel reasonably acceptable to the Corporation, in a form generally acceptable to the Corporation, to the effect that such Series B Preferred Stock to be offered for sale, sold, transferred, assigned, pledged or otherwise
distributed may be offered for sale, sold, transferred, assigned, pledged or otherwise distributed pursuant to an exemption from such registration, or (C) Holder provides the Corporation and its legal counsel with assurance reasonably

 American
Stock Transfer & Trust Company, LLC 
 6201 15th Avenue 

Brooklyn, New York 11219 
 Attention: Paula
Caroppoli 
 Ladies and Gentlemen: 
 Reference is made to that certain Securities Purchase Agreement, dated as of December 22, 2011 (the “Purchase Agreement”), by and between Marina Biotech, Inc., a Delaware corporation
(the “Company”), and Socius CG II, Ltd. (the “Holder”), pursuant to which the Company is issuing to the Holder (i) the Warrant (as defined in the Purchase Agreement), which is exercisable for shares of common
stock of the Company, $0.006 par value per share (the “Common Stock”) and (ii) the Additional Investment Right (as defined in the Purchase Agreement), which is exercisable for shares of Common Stock. 

This letter shall serve as our irrevocable authorization and direction to you (provided that you are the transfer agent of the Company at
such time): 
 (i) to issue shares of Common Stock upon the exercise of the Warrant (the “Warrant
Shares”) to or upon the order of the Holder from time to time upon delivery to you of an Exercise Notice, in the form attached hereto as Exhibit I. 

(ii) to issue shares of Common Stock upon the exercise of the Additional Investment Right (the “Additional
Investment Shares”) to or upon the order of the Holder from time to time upon delivery to you of an Investment Right Exercise Notice, in the form attached hereto as Exhibit II. 

You acknowledge and agree that so long as you have previously received (a) written opinion from the Company’s legal counsel
that either (i) a registration statement covering resales of the Warrant Shares or the Additional Investment Shares has been declared effective by the Securities and Exchange Commission (the “SEC”) under the Securities Act of
1933, as amended (the “1933 Act”), or (ii) that sales of the Warrant Shares or the Additional Investment Shares may be made in conformity with Rule 144 under the 1933 Act, and (b) if applicable, a copy of such registration
statement, then, on the trading day immediately following the date of receipt of the notice of exercise, you will credit such aggregate number of Warrant Shares or Additional Investment Shares (as the case may be) to which the Holder is entitled to
the Holder’s or its designee’s balance account with The Depository Trust Company (DTC) through its Deposit Withdrawal At Custodian (DWAC) system provided the Holder causes its bank or broker to initiate the DWAC transaction, and such
Warrant Shares and Additional Investment Shares should not be subject to any stop-transfer restriction or legend of any kind and shall otherwise be freely transferable on the books and records of the Company. 







 A form of written opinion from the Company’s outside legal counsel that a registration
statement covering resales of the Warrant Shares and Additional Investment Shares has been declared effective by the SEC under the 1933 Act is attached hereto as Exhibit III. 

The Company hereby confirms that no instructions other than as contemplated herein will be given to you by the Company with respect to
Warrant Shares and the Additional Investment Shares. The Company hereby agrees that it shall not replace you as the Company’s transfer agent, until such time as the Company provides written notice to you and Holder that a suitable replacement
has agreed to serve as transfer agent and to be bound by the terms and conditions of these Transfer Agent Instructions. 
 The
Company and you hereby acknowledge and confirm that complying with the terms of this agreement does not and shall not prohibit you from satisfying any and all fiduciary responsibilities and duties you may owe to the Company. 

The Company and you acknowledge that the Holder is relying on the representations and covenants made by the Company and you hereunder and
are a material inducement to the Holder to enter into the Purchase Agreement. The Company and you further acknowledge that without such representations and covenants made hereunder, the Holder would not enter into the Purchase Agreement and purchase
Securities pursuant thereto. 
 You may at any time resign as transfer agent hereunder by giving thirty (30) days prior
written notice of resignation to the Company and the Holder. Prior to the effective date of the resignation as specified in such notice, the Company will issue to you instructions authorizing delivery of Warrant Shares and Additional Investment
Shares to a substitute transfer agent selected by, and in the sole discretion of, the Company. If no successor transfer agent is named by the Company, you may apply to a court of competent jurisdiction in the State of Delaware for appointment of a
successor transfer agent and for an order to deposit the Warrant Shares and Additional Investment Shares with the clerk of any such court. 
 Each party hereto specifically acknowledges and agrees that a breach or threatened breach of any provision hereof will cause irreparable damage and that damages at law would be an inadequate remedy if
these Irrevocable Transfer Agent Instructions were not specifically enforced. Therefore, in the event of a breach or threatened breach by a party hereto, including, without limitation, the attempted termination of the agency relationship
created by this instrument, in addition to all other rights or remedies, an injunction restraining such breach and granting specific performance of the provisions of these Irrevocable Transfer Agent Instructions should issue without any requirement
to show any actual damage or to post any bond or other security.

 Re:     Marina Biotech, Inc. 
 Ladies and Gentlemen: 

We are counsel to Marina Biotech, Inc., a Delaware corporation (the “Company”), and have represented the Company in
connection with that certain Securities Purchase Agreement (the “Securities Purchase Agreement”) entered into by and between the Company and the investor named therein (the “Holder”) pursuant to which the Company
issued to the Holder a warrant (the “Warrant”) and an additional investment right (the “Additional Investment Right”), in each case, exercisable for shares of the Company’s common stock, $0.006 par value per
share (the “Common Stock”). Pursuant to the Securities Purchase Agreement, the Company agreed, among other things, to register the Registrable Securities (as defined in the Securities Purchase Agreement), including the shares
of Common Stock issuable upon exercise of the Warrant and the Additional Investment Right, under the Securities Act of 1933, as amended (the “1933 Act”). In connection with the Company’s obligations under the Securities
Purchase Agreement, on             , 20    , the Company filed a Registration Statement on Form S-1 (File
No. 333-            ) (the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) relating to the Registrable Securities
which names the Holder as a selling stockholder thereunder. 
 In connection with the foregoing, we advise you that a member of
the SEC’s staff has advised us by telephone that the SEC has entered an order declaring the Registration Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC’s staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened by, the SEC and the Registrable Securities are
available for resale under the 1933 Act pursuant to the Registration Statement. 
 This letter shall serve as our standing
opinion to you that the shares of Common Stock underlying the Warrant and the Additional Investment Right are freely transferable by the Holder pursuant to the Registration Statement. You need not require further letters from us to effect any future
legend-free issuance or reissuance of such shares of Common Stock to the Holder as contemplated by the Company’s Irrevocable Transfer Agent Instructions dated             ,

the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the SEC promulgated thereunder (the “Exchange Act”) with respect to, any Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock, or warrants or other rights to purchase Common Stock or any such securities, or any securities substantially similar to the Common Stock, (b) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of ownership of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or any such securities, or warrants or other rights to

bona fide gift of up to 10,000 shares of Common Stock to a charity or other non-profit entity and such charity or entity shall not be required to be bound by the terms of this Lock-Up
Agreement. For purposes of this paragraph, “immediate family” shall mean the undersigned and the spouse, any lineal descendent, father, mother, brother or sister of the undersigned.

divorce proceedings or otherwise, the transferee of such Common Stock shall take such Common Stock subject to this Lock-Up Agreement.

to pay to the order of Marina Biotech, Inc., a Delaware corporation (the “Company”), at 3830 Monte Villa Parkway, Bothell, Washington 98021, or at such other place as the Company may from time to time designate in writing, the
principal sum of $[            ], with interest, as follows: 
 1.
Purpose; Defined Terms. This Secured Promissory Note (this “Note”) is a full recourse secured promissory note being issued and delivered by Maker to the Company pursuant to the terms of (i) that certain Securities
Purchase Agreement, dated as of December 22, 2011 (as amended, restated, supplemented and otherwise modified from time to time, the “Purchase Agreement”), by and between Maker and the Company and (ii) that certain Warrant
to Purchase Common Stock issued by the Company to Maker, dated December [            ], 2011 (as amended, restated, supplemented and otherwise modified from time to time, the
“Warrant”), as good and valuable consideration and payment in full of: (x) the exercise price of certain securities of the Company to be issued to Maker in connection with the Warrant and the Additional Investment Right
contained in the Purchase Agreement or (y) the Warrant Premium. On or prior to the date hereof, Maker has executed and delivered to the Company a Security Agreement (as amended, restated, supplemented and otherwise modified from time to time,
the “Security Agreement”) in the form attached to the Purchase Agreement as Exhibit H thereto. Capitalized terms not otherwise defined herein shall have the meanings ascribed to such terms in the Purchase Agreement. 

2. Interest. The principal balance outstanding hereunder, from time to time, shall bear interest from and after the date hereof at
the rate of two percent (2.0%) per year. Interest shall be calculated on a simple interest basis and the number of days elapsed during the period for which interest is being calculated. Interest shall be payable on the Maturity Date.


  
 1 








 3. Payments. If not sooner paid, the entire unpaid principal
balance, interest thereon and any other charges due and payable under this Note shall be due and payable on the fourth
(4th) anniversary of the date of this Note or if
sooner upon an Acceleration Event (as defined below) (“Maturity Date”); provided, however, that in no event shall this Note or any amount hereunder be due or payable, nor shall an Acceleration Event (as defined below) or default (as
defined below) be deemed to exist, at any time that (a) the Company is in default of any of its material obligations under the Purchase Agreement, or any Warrant or other security of the Issuer issued pursuant to the Purchase Agreement or the
Warrant, or any loan agreement or other material agreement between the Maker and the Company, or (b) there are any Preferred Shares issued or outstanding. Maker shall have the right to prepay all or any part of the principal balance of this
Note at any time without penalty or premium, in which case all payments shall be first applied to interest, then to reduce the outstanding principal. This Note shall be subject to exchange, offset and cancellation at the option of the Company or
Maker as more fully set forth in the Certificate of Designations notwithstanding any transfer or assignment of this Note by the Company or any subsequent holder of this Note. In the event that the Purchase Agreement is terminated pursuant to Article
3 thereof prior to the issuance of any Preferred Shares pursuant thereto, then this Note (to the extent, and only to the extent, that this Note is issued as payment of the Warrant Premium) shall automatically be cancelled upon such termination and
shall be of no further force or effect. 
 4. Full Recourse Note. THIS IS A FULL RECOURSE PROMISSORY NOTE. Accordingly,
notwithstanding that Maker’s obligations under this Note are secured by the Promissory Note Collateral (as defined in the Security Agreement), in the event of a material default hereunder, the Company shall have full recourse to all the other
assets of Maker. Moreover, the Company shall not be required to proceed against or exhaust any Promissory Note Collateral, or to pursue any Promissory Note Collateral in any particular order, before the Company pursues any other remedies against
Maker or against any of Maker’s assets. It is expressly understood and agreed that upon the occurrence of an Acceleration Event (as defined below), Maker shall be entitled to satisfy all of the obligations outstanding hereunder and under any
similar note of Maker by surrendering to the Company for cancellation all Preferred Shares owned by Maker as more fully set forth in the Certificate of Designation. 
 5. Default. Subject to the proviso in the first sentence of Section 1 above: any one or more of the following shall constitute a “default” under this Note: (i) a default in the
payment when due of any amount hereunder, (ii) Maker’s refusal to perform any material term, provision or covenant under this Note, (iii) the commencement of any liquidation, receivership, bankruptcy, assignment for the benefit of
creditors or other debtor-relief proceeding by or against Maker, (iv) any cessation of operations by Maker or Maker admits it is otherwise generally unable to pay its debts as such debts become due, and (v) subject to Sections 2 and 3 of
the Security Agreement, the Promissory Note Collateral is transferred by Maker without being replaced by Promissory Note Collateral of equal or greater fair market value within two (2) business days of the date of transfer. 

6. Default Rights. Subject to the proviso in the first sentence of Section 1 above: 

i. Upon the occurrence of a default specified in clauses (i) or (ii) of Section 5 above, the Company may, at its election,
declare the entire balance of principal and interest under this Note immediately due and payable or, upon the occurrence of a default specified in clause (iii) of Section 5 above, the entire balance of principal and interest under this
Note shall 

  
 2 








 
automatically become immediately due and payable without any action by the Company (each, an “Immediate Acceleration Event”). A delay by the Company in exercising any right of
acceleration after a default shall not constitute a waiver of the default or the right of acceleration or any other right or remedy for such default. The failure by the Company to exercise any right of acceleration as a result of a default shall not
constitute a waiver of the right of acceleration or any other right or remedy with respect to any other default, whenever occurring. 
 ii. Further, upon the occurrence a default specified in clauses (iv) or (v) of Section 5 above, following thirty (30) business days notice from the Company to Maker specifying the
default and demanded manner of cure for such default, if such default has not been cured by the expiration of such thirty (30) business day period, the Company may, at its election, declare the entire balance of principal and interest under
this Note immediately due and payable (a “Notice Acceleration Event” and, together with an Immediate Acceleration event, each an “Acceleration Event”). 

iii. Upon the occurrence of an Acceleration Event, the Company shall thereupon (and only thereupon) and thereafter have any and all of
the rights and remedies to which a secured party is entitled after a default under the Security Agreement and the applicable Uniform Commercial Code, as then in effect. 
 iv. The rights, privileges, powers and remedies of the Company shall be cumulative, and no single or partial exercise of any of them shall preclude the further or other exercise of any of them. Any
waiver, permit, consent or approval of any kind by the Company of any default hereunder, or any such waiver of any provisions or conditions hereof, must be in writing and shall be effective only to the extent set forth in writing. Any proceeds of
any disposition of the Promissory Note Collateral by the Company in accordance with this Section 6, or any part thereof, may be applied by the Company to the payment of expenses incurred by the Company in connection with the foregoing, and the
balance of such proceeds shall be applied by the Company toward the payment of the Obligations (as defined in the Security Agreement). Notwithstanding anything contained in this Note to the contrary, it is expressly understood and agreed that
neither the Company nor any other holder of this Note shall have the right to proceed against the Promissory Note Collateral or Maker in connection with the Promissory Note until the occurrence of an Acceleration Event. 

7. Security. This Note and the obligations hereunder are secured to the extent and in the manner set forth in the Security
Agreement. By delivery of this Note, Maker hereby certifies to Company its good faith belief that it has complied with Section 1(a) of the Security Agreement on the date hereof. 

8. Additional Terms. 
 a. No Waiver. The acceptance by the Company of payment of a portion of any installment when due or an entire installment but after it is due shall neither cure nor excuse the default caused by the
failure of Maker timely to pay the whole of such installment and shall not constitute a waiver of the Company’s right to require full payment when due of any future or succeeding installments. 

  
 3 








 b. No Oral Waivers or Modifications. No provision of this Note may be waived or
modified orally, but only in a writing signed by the Company and Maker. 
 c. Attorney Fees. The prevailing party in any
action by the Company to collect any amounts due under this Note shall be entitled to recover its reasonable attorneys fees and costs. 
 d. Governing Law. This Note has been executed and delivered in, and is to be construed, enforced, and governed according to the internal laws of, the State of New York without regard to its
principles of conflict of laws that would require or permit the application of the laws of any other jurisdiction. 
 e.
Severability. Whenever possible, each provision of this Note shall be interpreted in such manner as to be effective and valid under applicable law. However, if any provision of this Note shall be held to be prohibited by or invalid under
applicable law, it shall be ineffective only to the extent of such prohibition or invalidity without invalidating the remainder of that provision or the other provisions of this Note. 

f. Currency. Principal and interest due hereunder shall be payable in lawful money of the United States of America and shall be
payable to the Company at the address of Maker, or at such other address as may be specified in a written notice to Maker given by the Company. 
 g. Weekend; Holidays. If any payment on this Note shall become due on a Saturday, Sunday or a bank or legal holiday in the United States of America, such payment shall be made on the next
succeeding business day in the United States of America. 
 h. Usury. If interest payable under this Note is in excess of
the maximum permitted by law, the interest chargeable hereunder shall be reduced to the maximum amount permitted by law and any excess over the maximum amount permitted by law shall be credited to the principal balance of this Note and applied to
the same and not to the payment of interest. 
 i. Entire Agreement. This Note, the Warrant, the Security Agreement, the
Purchase Agreement and the other Transaction Documents contain the entire understanding of the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral or written, with respect to such matters.

 IN WITNESS WHEREOF, this Secured Promissory Note has been executed as of the date first written above.

 Exhibit H 
 Form of Security Agreement 







 SECURITY AGREEMENT 

This SECURITY AGREEMENT, dated as of [            ], 20[ ] (this
“Agreement”), is made by and between Socius CG II, Ltd., a Bermuda exempted company (“Grantor”), and Marina Biotech, Inc., a Delaware corporation (“Secured Party”). 

WHEREAS, pursuant to the terms of that certain Securities Purchase Agreement, dated as of December 22, 2011, by and between Secured
Party and Grantor (as amended, restated, supplemented and otherwise modified from time to time, the “Purchase Agreement”), Secured Party has issued to Grantor (i) that certain Warrant to Purchase Common Stock, dated December
[            ], 2011 (as amended, restated, supplemented and otherwise modified from time to time, the “Warrant”), which is exercisable for shares of common stock, $0.006
par value per share, of Secured Party (the “Common Stock”) and (ii) that certain additional investment right contained in the Purchase Agreement (the “Additional Investment Right”), which is exercisable for
shares of Common Stock; 
 WHEREAS, to the extent elected by Grantor, in its sole discretion, Secured Party has agreed to accept
one or more full recourse secured promissory notes (as amended, restated, supplemented and otherwise modified from time to time, collectively, the “Promissory Notes”) in lieu of cash paid in satisfaction of: (i) the exercise
price of any of the shares of Common Stock issuable upon exercise of the Warrant (the “Warrant Shares”) and/or the Additional Investment Right (the “Additional Investment Shares”), and/or (ii) the Warrant
Premium; 
 WHEREAS, in connection with the initial election by Grantor to pay the exercise price of the Warrant Shares and/or
the Additional Investment Shares, and/or to pay the Warrant Premium, through Grantor’s issuance of a Promissory Note to Secured Party, Grantor must execute and deliver to Secured Party a security agreement in substantially the form hereof
simultaneously with the issuance of such Promissory Note; and 
 WHEREAS, Grantor wishes to grant security interests in favor of
Secured Party as herein provided; 
 NOW, THEREFORE, in consideration of the promises contained herein and for other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 

1. Grant of Security Interest. Grantor hereby grants to Secured Party, to secure the payment and performance when due in
full of any indebtedness arising pursuant to the Promissory Notes (the “Obligations”), a security interest in all of Grantor’s right, title, and interest in and to all of the following (subject to Section 2 and
Section 3 below), now owned or hereafter acquired or arising (together the “Collateral” and, with respect to the portion of the Collateral that secures any given Promissory Note, the “Promissory Note
Collateral”): 







 (a) Publicly traded or otherwise free-trading shares of common stock, or
shares of preferred stock, or bonds, notes and/or debentures (collectively, “Pledged Securities”) with a fair market value at least equal to the principal amount of, and accrued interest on, the Promissory Notes then outstanding,
based upon the trading price of such securities on (i) the Pink Sheets, OTCQB, OTC Bulletin Board, the NASDAQ Capital Market, the NASDAQ Global Market, the NASDAQ Global Select Market, the NYSE Amex, or the New York Stock Exchange, if
applicable or (ii) otherwise, the fair market value of such Pledged Securities as set forth on the books and records of Grantor; 
 (b) all rights of Grantor with respect to or arising out of the Pledged Securities, including voting rights, and all equity and debt securities and other property distributed or distributable with respect
thereto as a result of merger, consolidation, dissolution, reorganization, recapitalization, stock split, stock dividend, reclassification, exchange, redemption, or other change in capital structure; and 

(c) all proceeds, replacements, substitutions, accessions and increases in any of the Collateral: 

provided, that (i) the Promissory Note Collateral shall not include the Warrant, the Additional Investment Right, the Warrant Shares, or the
Additional Investment Shares issued in exchange for or in connection with the Promissory Note. 
 Grantor shall provide to Secured Party, at the
written request made from time to time by the Secured Party, a schedule listing the Pledged Securities and the custodian thereof, including any changes arising under Section 3 hereof, which schedule shall be in form and substance reasonably
satisfactory to the Secured Party. Grantor shall maintain such lien as a lien and security interest in the Pledged Securities, provided that Grantor shall have no obligation to maintain such lien in such securities to the extent such fair market
value is greater than the principal amount of, and accrued interest on, the Promissory Notes then outstanding. 
 Notwithstanding anything to
the contrary herein, the fair market value of the Promissory Note Collateral (as determined in accordance with this Section 1) shall at all times equal or exceed the amount of the obligations secured thereby. 

2. Margin Regulations. Notwithstanding the foregoing, with respect to any Pledged Securities that consist of “Margin
Stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System of the United States (“Regulation U”)), such portion of the fair market value of such Pledged Securities included as Collateral
hereunder shall not exceed the maximum amount permitted by applicable law to be pledged as Collateral hereunder, including, without limitation, under Regulation U. 
 3. Replacement Securities. It is expressly understood and agreed that Grantor shall at all times prior to an Acceleration Event (as defined in the Promissory Notes) have the right to sell,
dispose of, replace or substitute any securities or other assets that constitute Collateral hereunder. So long as any Obligations remain outstanding, in the event that Grantor sells or disposes of any Pledged Securities or to the extent any
securities or other assets that were Collateral hereunder cease to be Collateral pursuant to Section 2 above, Grantor shall within the time period set forth in the Promissory Notes, provide replacement securities of equal or greater fair
market value determined in accordance with Section 1(a) above. 

  
 -- 2 --









 4. Rights With Respect to Distributions. Until the occurrence of an
Acceleration Event under any given Promissory Note, Grantor shall be entitled to receive any and all dividends and distributions made with respect to the Pledged Securities and any other Collateral. However, upon the occurrence of any such
Acceleration Event, Secured Party shall have the sole right (unless otherwise expressly agreed by Secured Party in writing) to receive and retain dividends and distributions and apply them to the outstanding balance of the Promissory Note under
which such Acceleration Event has occurred or hold them as Promissory Note Collateral, at Secured Party’s election. 

5. Voting Rights. Until the occurrence of an Acceleration Event under any given Promissory Note, Grantor shall be entitled
to exercise all voting rights pertaining to the Pledged Securities and any other Promissory Note Collateral. However, upon the occurrence of any such Acceleration Event, all rights of Grantor to exercise the voting rights that Grantor would
otherwise be entitled to exercise with respect to the Promissory Note Collateral shall cease and (unless otherwise agreed by Secured Party) all such rights shall thereupon become vested in Secured Party, which shall thereupon have the sole right to
exercise such rights. 
 6. Financing Statement; Further Assurances. Grantor agrees, concurrently with
executing this Agreement, that Secured Party (and to the extent authorized by Secured Party, its counsel and other representatives) is authorized, at any time and from time to time, to execute, deliver and file or record UCC-1 financing statements,
amendments and continuations to financing statements, and instructions relating to the Promissory Note Collateral in favor of Secured Party, and any similar financing statements in any jurisdiction in which Secured Party reasonably determines such
filing or delivery to be necessary or advisable. Grantor further agrees to provide Secured Party with written notice of any change in its name, form of organization, jurisdiction of organization or location of its chief executive office or principal
place of business within thirty (30) business days of such change. Grantor further agrees that upon the occurrence of an Acceleration Event under any given Promissory Note, and at any time and from time to time thereafter until the cause of
such Acceleration Event has been cured, Grantor shall, at the reasonable request of the Secured Party and at the Grantor’s expense promptly execute and deliver all further instruments and documents including, without limitation, collateral
assignments, Form UCC-1 financing statements or amendments or continuations thereof, and consents to the exercise by Secured Party of all of Secured Party’s rights and remedies hereunder, under any supplement hereto or applicable law with
respect to the Collateral, and do or cause to be done such further acts as may be reasonably necessary or proper in Secured Party’s opinion to evidence, maintain and enforce Secured Party’s security interest in the Collateral and to
otherwise effectuate the provisions or purposes of this Agreement or any supplement hereto including, without limitation, requiring delivery of the Promissory Note Collateral to Secured Party to hold as secured party. 

7. Powers of Secured Party. Grantor agrees that upon the occurrence of an Acceleration Event under any given Promissory
Note, it shall appoint Secured Party as Grantor’s true and lawful attorney-in-fact to perform any and all of the following acts, which power shall be coupled with an interest, shall be irrevocable until the Obligations are paid and performed in
full, and may be exercised from time to time by Secured Party in its discretion to take any action which 

  
 -- 3 --









 
shall be required for Secured Party (i) to exercise voting and consent rights with respect to Promissory Note Collateral in accordance with this Agreement, (ii) to receive, endorse and
collect all instruments or other forms of payment made payable to Grantor in respect of the Promissory Note Collateral or any part thereof and to give full discharge for the same, (iii) to perform or cause the performance of any obligation of
Grantor hereunder in Grantor’s name or otherwise, (iv) to liquidate any Promissory Note Collateral pledged to Secured Party hereunder and to apply proceeds thereof to the payment of the Obligations or to place such proceeds into a cash
Promissory Note Collateral account or to transfer the Promissory Note Collateral into the name of Secured Party, all at Secured Party’s sole discretion, (v) to enter into any extension, reorganization or other agreement relating to or
affecting the Promissory Note Collateral, and, in connection therewith, to deposit or surrender control of the Promissory Note Collateral, (vi) to accept other property in exchange for the Promissory Note Collateral, (vii) to make any
compromise or settlement Secured Party deems desirable or proper in respect of the Promissory Note Collateral or the Obligations, and (viii) to execute on Grantor’s behalf and in Grantor’s name any documents required in order to give
Secured Party a continuing first lien upon the Promissory Note Collateral or any part thereof. 
 8. No Waiver.
The acceptance by Secured Party of payment of a portion of any installment when due or an entire installment but after it is due shall neither cure nor excuse the Acceleration Event caused by the failure of Grantor timely to pay the whole of such
installment and shall not constitute a waiver of Secured Party’s right to require full payment when due of any future or succeeding installments. 
 9. Default. Upon the occurrence of an Acceleration Event under any given Promissory Note, Secured Party shall have the rights set forth in Section 10 below. 

10. Default Rights. 
 (a) Upon the occurrence of an Acceleration Event under any given Promissory Note, Secured Party shall thereupon and thereafter have any and all of the rights and remedies to which a secured party is
entitled after a default under the applicable Uniform Commercial Code, as then in effect. It is expressly understood and agreed that prior to such time, Secured Party shall not take any action in respect of the Collateral. 

(b) In addition to its other rights and remedies, Grantor agrees that, upon the occurrence of an Acceleration Event under
any given Promissory Note, Secured Party may in its sole discretion do or cause to be done any one or more of the following (all to the extent reasonable): 
 (i) proceed to realize upon the Promissory Note Collateral or any portion thereof as provided by law, and without liability for any diminution in price which may have occurred, sell the Promissory Note
Collateral or any part thereof, in such manner, whether at any public or private sale, and whether in one lot as an entirety, or in separate portions, and for such price and other terms and conditions as is commercially reasonable given the nature
of the Promissory Note Collateral; 

  
 -- 4 --









 (ii) if notice to Grantor is required, give written notice to Grantor at
least ten days before the date of sale of the Promissory Note Collateral or any portion thereof; 
 (iii)
transfer all or any part of the Promissory Note Collateral into Secured Party’s name or in the name of its nominee or nominees; or 
 (iv) vote all or any part of the Promissory Note Collateral (whether or not transferred into the name of Secured Party) and give all consents, waivers and ratifications in respect of the Promissory Note
Collateral and otherwise act with respect thereto, as though Secured Party were the outright owner thereof. 

(c) Grantor acknowledges that all or part of foreclosure of the Promissory Note Collateral may be restricted by state or
federal securities laws, Secured Party may be unable to effect a public sale of all or part of the Promissory Note Collateral, that a public sale is or may be impractical and inappropriate and that, in the event of such restrictions, Secured Party
thus may be compelled to resort to one or more private sales to a restricted group of purchasers who will be obliged to agree, among other things, to acquire the Promissory Note Collateral for their own account, for investment and not with a view to
its distribution or resale. Grantor agrees that if reasonably necessary Secured Party may resort to one or more sales to a single purchaser or a restricted or limited group of purchasers. Secured Party shall not be obligated to make any sale or
other disposition, unless the terms thereof shall be satisfactory to it. 
 (d) If, in the opinion of Secured
Party based upon written advice of counsel, any consent, approval or authorization of any federal, state or other governmental agency or authority should be necessary to effectuate any sale or other disposition of any Promissory Note Collateral,
Grantor shall execute all such applications and other instruments as may reasonably be required in connection with securing any such consent, approval or authorization, and will otherwise use its commercially reasonable efforts to secure the same.

 (e) The rights, privileges, powers and remedies of Secured Party shall be cumulative, and no single or partial
exercise of any of them shall preclude the further or other exercise of any of them. Any waiver, permit, consent or approval of any kind by Secured Party of any Acceleration Event, or any such waiver of any provisions or conditions hereof, must be
in writing and shall be effective only to the extent set forth in writing. Any proceeds of any disposition of the Promissory Note Collateral by the Secured Party in accordance with this Section 10, or any part thereof, may be applied by Secured
Party to the payment of expenses incurred by Secured Party in connection with the foregoing, and the balance of such proceeds shall be applied by Secured Party toward the payment of the Obligations. Notwithstanding anything contained herein to the
contrary, it is expressly understood and agreed that the Company shall have no rights to proceed against the Collateral until the occurrence of an Acceleration Event under any given Promissory Note. 

  
 -- 5 --









 11. Attorney Fees. The prevailing party in any action by Secured Party
to collect any amounts due under this Agreement and/or the Promissory Notes shall be entitled to recover its reasonable attorneys fees and costs. 
 12. Entire Agreement, Amendments; Etc. THIS AGREEMENT, TOGETHER WITH THE PROMISSORY NOTES, THE PURCHASE AGREEMENT, THE WARRANT, AND THE OTHER TRANSACTION DOCUMENTS (AS DEFINED IN THE
PURCHASE AGREEMENT), REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES SOLELY WITH RESPECT TO THE SUBJECT MATTER HEREOF AND THEREOF AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
THERE ARE NO UNWRITTEN AGREEMENTS BETWEEN THE PARTIES. No waiver of any provision of this Agreement, and no consent to any departure by Grantor herefrom, shall in any event be effective unless the same shall be in writing and signed by Secured
Party, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given, provided that any party may give a waiver in writing as to itself. No amendment of any provision of this Agreement
shall be effective unless the same shall be in writing and signed by both Grantor and Secured Party. 
 13.
Governing Law; Jurisdiction; Service of Process; 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 TO, 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. 
 14. Addresses for
Notices. All notices and other communications provided for hereunder (a) shall be given in the form and manner set forth in the Warrant and (b) shall be delivered, (i) in the case of notice to Grantor, by delivery of such
notice to Grantor at its address specified in the Warrant or at such other address as shall be designated by Grantor in a written notice to Secured Party in accordance with the provisions thereof, and (ii) in the case of notice to Secured
Party, by delivery of such notice to Secured Party at its address specified in the Warrant or at such other address as shall be designated by Secured Party in a written notice to Grantor in accordance with the provisions thereof.

the date the Obligations are paid and performed in full and no Promissory Notes remain outstanding (the “Termination Date”), it being understood and agreed that the Obligations shall be deemed to be paid and performed in full upon a
redemption of the Series B Preferred Stock by the Secured Party as contemplated by clause (ii) of Section 6(d) of the Certificate of Designations of Preferences, Rights and Limitations of the Series B Preferred Stock. Secured Party agrees
that from and after the Termination Date, Secured Party will, from time to time, at the expense and at the request of Grantor, promptly following any such request of Grantor: (i) deliver to Grantor such termination statements, releases,
assignments or other agreements or instruments, in form and substance reasonably satisfactory to Grantor, as Grantor may reasonably request to evidence the termination of this Agreement, the payment or other satisfaction in full of all the
Obligations and to evidence, effect or confirm the release and termination of any and all security interests and other liens created hereunder or pursuant to the Promissory Notes or otherwise securing the Obligations, and (ii) deliver any
Collateral held by Secured Party to Grantor or, as applicable, instruct the relevant custodian to deliver such Collateral to Grantor. Except as provided in Sections 12 through 16, which shall survive the Termination Date, from and

 16.

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. In the event that any signature is delivered by facsimile transmission or by an
e-mail which contains a portable document format (.pdf) file of an executed signature page, such signature page 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 signature page were an original thereof. Any party delivering an executed counterpart of this Agreement by facsimile or other electronic method of transmission also shall deliver an original executed counterpart of this
Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. 
 (b) Any provision of this Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in
that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction.

upon and inure to the benefit of the parties and their successors and permitted assigns. The Secured Party may not assign this Agreement or any rights or obligations hereunder without the prior written consent of Grantor, which consent will not be
