Rights Agreement (as defined below) and any other agreement entered into between the Subscriber and the Company relating to this subscription (collectively, the “Transaction Documents”) to be performed or discharged on or prior to
the Closing in which such Subscriber participates, the Subscriber shall be legally bound to purchase the Units pursuant to the terms and conditions set forth in this Agreement. For the avoidance of doubt, upon the occurrence of the failure by the
Company to fully, faithfully and punctually perform and discharge any of its duties, obligations and responsibilities as set forth in any of the Transaction Documents, which shall have been performed or otherwise discharged prior to the Closing (as
defined below), the Subscriber may, on or prior to the Closing, at its sole and absolute discretion, elect not to purchase the Units and provide instructions to the Company to receive the full and immediate refund of the Aggregate Purchase Price. In
the event the Closing does not take place because of (i) the election not to purchase the Units by the Subscriber or (ii) the failure to effectuate the Initial Closing (as defined below) on or prior to March 27, 2015 (unless extended
in the discretion of the Board of Directors) for any reason or no reason, this Agreement and any other Transaction Documents shall thereafter be terminated and have no force or effect, and the parties shall take all steps, including the execution of
instructions to the Company, to ensure that the Aggregate Purchase Price shall promptly be returned or caused to be returned to the Subscriber without interest thereon or deduction therefrom. 

(b) Closing. The closing of the purchase and sale of the Units hereunder (the “Closing”) shall take place at such time and
place as determined by the Company and may take place in one of more closings. Closings shall take place on a Business Day promptly following the satisfaction of the conditions set forth in Section 6 below, as determined by the Company (the
“Closing Date”). “Business Day” shall mean from the hours of 9:00 a.m. (Eastern Time) through 5:00 p.m. (Eastern Time) of a day other than a Saturday, Sunday or other day on which commercial banks in New York, New York are

“Initial Closing Date.” Subsequent closings (each a “Subsequent Closing”) will be held until the earlier to occur of: (i) the date on which the Maximum Offering Amount has been subscribed for and accepted by
the Company, and (ii) April 30, 2015. The Offering may be extended up to May 15, 2015 (the “Final Closing” and such date of the Final Closing, the “Final Closing Date”), without additional notice to
Subscribers. Officers, directors and affiliates of the Company and the placement agent, if any, may purchase Units in the Offering. 
 (c)
Following Acceptance or Rejection. The Subscriber acknowledges and agrees that this Agreement and any other documents delivered in connection herewith will be held by the Company. Prior to the Company’s execution, in the event that this
Agreement is not accepted by the Company for whatever reason, which the 

  
 - 3 - 








 
Company expressly reserves the right to do, this Agreement, the Aggregate Purchase Price received (without interest thereon) and any other documents delivered in connection herewith will be
returned to the Subscriber at the address of the Subscriber as set forth in this Agreement. If this Agreement is accepted by the Company, the Company is entitled to treat the Aggregate Purchase Price received as an interest free loan to the Company
until such time as the Subscription is accepted. 
 (d) Favored Nations Provision. For any Subscriber that elected to receive
Shares (and not Preferred Shares) in connection with its purchase of Units hereunder, for a period beginning on the Closing Date and ending on the date that is the earlier of (i) twenty-four (24) months from the Final Closing Date,
(ii) the date the Company consummates a financing (excluding proceeds from this Offering) in which the Company receives gross proceeds of at least Ten Million Dollars ($10,000,000) and (iii) the date the Company’s Common Stock is
listed for trading on a national securities exchange (which, for purposes hereof shall mean The New York Stock Exchange, the NYSE MKT, the Nasdaq Global Select Market, the Nasdaq Global Market or the Nadsaq Capital Market), other than in connection
with (i) the issuance of shares of Common Stock or options to purchase Common Stock issued to directors, officers, employees or consultants of the Company pursuant to any Approved Stock Plan, provided that (A) all such issuances (taking
into account the shares of Common Stock issuable upon exercise of such options) after the Final Closing Date pursuant to this clause (i) do not, in the aggregate, exceed more than 7,116,204 shares of Common Stock, in the aggregate (including
options) (as adjusted for stock splits, combinations and similar transactions) and (B) the exercise price of any such options is not lowered after issuance by subsequent amendment thereof, none of such options are amended subsequent to issuance
to increase the number of shares issuable thereunder and none of the terms or conditions of any such options are subsequent to issuance otherwise materially changed in any manner that adversely affects any of the Subscribers; (ii) the issuance
of shares of Common Stock issued upon the conversion or exercise of Convertible Securities or contractual agreements (other than options to purchase Common Stock or other equity incentive awards issued pursuant to an Approved Stock Plan that are
covered by clause (i) above) issued prior to the date hereof, provided that the conversion price of any such Convertible Securities (other than options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by
clause (i) above) is not lowered by subsequent amendment, none of such Convertible Securities (other than standard options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) are
subsequently amended to increase the number of shares issuable thereunder and none of the terms or conditions of any such Convertible Securities (other than options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered
by clause (i) above) are otherwise materially changed in any manner that adversely affects any of the Subscribers; (iii) the shares of Common Stock issuable upon conversion of the Preferred Shares or the Warrants and (iv) the
issuances set forth on Schedule 2(d) (collectively, the foregoing (i) through (iv) are “Excepted Issuances”), if at any time the Company shall issue any Common Stock or securities convertible into or
exercisable for shares of Common Stock (or modify any of the foregoing which may be outstanding) to any person or entity at a price per share or conversion or exercise price per share which shall be less than $0.75 per share, being the per share
price of the Shares hereunder (disregarding any value attributable to the Warrants) or as in effect at such time, without consent of Subscribers holding at least 60% of the then outstanding Units (the “Required Approval”) (the
“Lower Price Issuance”) and other than with regard to Excepted Issuances, then the Company shall issue the Subscriber such number of additional Shares to reflect such lower price for the Shares such that the Subscriber shall hold
such number of Shares, in total, had Subscriber paid a per Share price equal to the Lower Price Issuance (with any fractional Shares rounded down to the nearest whole number). Common Stock issued or issuable by the Company for no consideration
or for consideration that cannot be determined at the time of issue will be deemed issuable or to have been issued for $0.01 per share of Common Stock. All “Favored Nations” rights of a Subscriber who elected to purchase Preferred
Shares shall be governed by the Series E Certificate of Designation. Notwithstanding anything herein or in any other agreement to the contrary, the Company shall only be required to make a single adjustment with respect to any Lower Price
Issuance, regardless of the existence of multiple basis therefore. For purposes of this Section 2(d), “Approved Stock Plan” shall mean any employee benefit plan which has been approved by the board of directors of the Company
on or prior to the date hereof pursuant to which shares of Common Stock and standard options to purchase Common Stock may be issued to any employee, officer or director for services provided to the Company in their capacity as such (including,
without limitation, any adjustments to the number of shares reserved for issuance thereunder as a result of the operation of any evergreen provisions), “Convertible Securities” shall mean any stock or other security (other than

 (e) Extraordinary Events Regarding Common Stock. In the event that the Company shall
(a) issue additional shares of Common Stock as a dividend or other distribution on outstanding Common Stock, (b) subdivide its outstanding shares of Common Stock, or (c) combine its outstanding shares of the Common Stock into a
smaller number of shares of Common Stock, then, in each such event, the Purchase Price shall, simultaneously with the happening of such event, be adjusted by multiplying the then Purchase Price by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the
Purchase Price then in effect. The Purchase Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein. The number of Units that the Subscriber shall thereafter be entitled to
receive (including number of shares of Conversion Shares or Warrant Shares the Subscriber may thereafter be entitled to receive upon conversion of the Preferred Shares or exercise of the Warrants, as the case may be) shall be adjusted to a number
determined by multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section) be issuable on such conversion or exercise by a fraction of which (a) the numerator is the Purchase Price that would
otherwise (but for the provisions of this Section) be in effect, and (b) the denominator is the Purchase Price then in effect. 
 (f)
Certificate as to Adjustments. In each case of any adjustment or readjustment in (i) the Shares, (ii) the Preferred Shares, (iii) the number of Conversion Shares issuable upon conversion of the Preferred Shares (iii) the
number of Warrant Shares issuable upon the exercise of the Warrants, (iv) the exercise price of the Warrants and/or (v) the conversion price of the Preferred Shares, the Company, at its expense, will promptly cause its Chief Financial
Officer or other appropriate designee to compute such adjustment or readjustment in accordance with the terms hereof and of the Series E Certificate of Designation or the Warrant, as applicable, and prepare a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Company will forthwith mail a copy of each such certificate to the Subscriber. 

 

	3.	THE SUBSCRIBER’S REPRESENTATIONS, WARRANTIES AND COVENANTS 

 Each Subscriber,
severally and not jointly, hereby acknowledges, agrees with and represents, warrants and covenants to the Company, as follows: 
 (a) The
Subscriber has full power and authority to enter into this Agreement, the execution and delivery of which has been duly authorized, if applicable, and this Agreement constitutes a valid and legally binding obligation of the Subscriber, except as may
be limited by bankruptcy, reorganization, insolvency, moratorium and similar laws of general application relating to or affecting the enforcement of rights of creditors, and except as enforceability of the obligations hereunder are subject to
general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or law). 
 (b) The
Subscriber acknowledges its understanding that the Offering and sale of the Securities is intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) of the Securities Act and the provisions of Regulation D
promulgated thereunder (“Regulation D”). In furtherance thereof, the Subscriber represents and warrants to the Company and its affiliates as follows: 

(i) The Subscriber realizes that the basis for the exemption from registration may not be available if, notwithstanding the
Subscriber’s representations contained herein, the Subscriber is merely acquiring the Securities for a fixed or determinable period in the future, or for a market rise, or for sale if the market does not rise. The Subscriber does not have any
such intention. 
 (ii) The Subscriber realizes that the basis for exemption would not be available if the Offering is part
of a plan or scheme to evade registration provisions of the Securities Act or any applicable state or federal securities laws, except sales pursuant to a registration statement or sales that are exempted under the Securities Act. 

  
 - 5 - 








 (iii) The Subscriber is acquiring the Securities solely for the Subscriber’s
own beneficial account, for investment purposes, and not with a view towards, or resale in connection with, any distribution of the Securities. 

(iv) The Subscriber has the financial ability to bear the economic risk of the Subscriber’s investment, has adequate means
for providing for its current needs and contingencies, and has no need for liquidity with respect to an investment in the Company. 

(v) The Subscriber and the Subscriber’s attorney, accountant, purchaser representative and/or tax advisor, if any
(collectively, the “Advisors”) has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of a prospective investment in the Securities. If other than an individual, the
Subscriber also represents it has not been organized solely for the purpose of acquiring the Securities. 
 (vi) The
Subscriber (together with its Advisors, if any) has received all documents requested by the Subscriber, if any, and has carefully reviewed them and understands the information contained therein, prior to the execution of this Agreement. 

(c) The Subscriber is not relying on the Company or any of its employees, agents, sub-agents or advisors with respect to the legal, tax,
economic and related considerations involved in this investment. The Subscriber has relied on the advice of, or has consulted with, only its Advisors. Each Advisor, if any, has disclosed to the Subscriber in writing (a copy of which is annexed to
this Agreement) the specific details of any and all past, present or future relationships, actual or contemplated, between the Advisor and the Company or any affiliate or sub-agent thereof. 

(d) The Subscriber has carefully considered the potential risks relating to the Company and a purchase of the Securities, and fully
understands that the Securities are a speculative investment that involves a high degree of risk of loss of the Subscriber’s entire investment. Among other things, the Subscriber has carefully considered each of the risks described under the
heading “Risk Factors” in the Company’s SEC Documents (as defined below) and any additional disclosures in the nature of Risk Factors described herein. 

(e) The Subscriber will not sell or otherwise transfer any Securities without registration under the Securities Act or an exemption therefrom,
and fully understands and agrees that the Subscriber must bear the economic risk of its purchase because, among other reasons, the Securities have not been registered under the Securities Act or under the securities laws of any state and, therefore,
cannot be resold, pledged, assigned or otherwise disposed of unless they are subsequently registered under the Securities Act and under the applicable securities laws of such states, or an exemption from such registration is available. In
particular, the Subscriber is aware that the Securities are “restricted securities,” as such term is defined in Rule 144 promulgated under the Securities Act (“Rule 144”), and they may not be sold pursuant to Rule 144
unless all of the conditions of Rule 144 are met. The Subscriber also understands that the Company is under no obligation to register the Securities on behalf of the Subscriber or to assist the Subscriber in complying with any exemption from
registration under the Securities Act or applicable state securities laws. The Subscriber understands that any sales or transfers of the Securities are further restricted by state securities laws and the provisions of this Agreement. 

(f) No oral or written representations or warranties have been made, or information furnished, to the Subscriber or its Advisors, if any, by
the Company or any of its officers, employees, agents, sub-agents, affiliates, advisors or subsidiaries in connection with the Offering, other than any representations of the Company contained herein, and in subscribing for the Units the Subscriber
is not relying upon any representations other than those contained herein. 
 (g) The Subscriber’s overall commitment to investments
that are not readily marketable is not disproportionate to the Subscriber’s net worth, and an investment in the Securities will not cause such overall commitment to become excessive.

substantially the following legend: 
 “[NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE

REQUESTED BY THE COMPANY), IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING,
THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.”

(i) while a registration statement covering the resale of such Securities is effective under the Securities Act, (ii) following any sale of such Securities pursuant to Rule 144 (assuming the transferor is not an affiliate of the Company),
(iii) if such Securities are eligible to be sold, assigned or transferred under Rule 144 and the Subscriber is not an affiliate of the Company (provided that the Subscriber provides the Company with reasonable assurances that such Securities
are eligible for sale, assignment or transfer under Rule 144 which shall not include an opinion of the Subscriber’s counsel), (iv) in connection with a sale, assignment or other transfer (other than under Rule 144), provided that the
Subscriber provides the Company with an opinion of counsel (at the expense of the Company), in a form generally acceptable to the Company, to the effect that such sale, assignment or transfer of the Securities may be made without registration under
the applicable requirements of the Securities Act or (v) if such legend is not required under applicable requirements of the Securities Act (including, without limitation, controlling judicial interpretations and pronouncements issued by the
SEC). If a legend is not required pursuant to the foregoing, the Company shall no later than three (3) business days following the delivery by the Subscriber to the Company or the transfer agent (with notice to the Company) of a legended
certificate representing such Securities (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer, if applicable), together with any other deliveries from the Subscriber
as may be required above in this Section 3(i), as directed by the Subscriber, either: (A) provided that the Company’s transfer agent is participating in the DTC Fast Automated Securities Transfer Program and such Securities are shares
of Shares, Conversion Shares or Warrant Shares, credit the aggregate number of shares of Common Stock to which the Subscriber shall be entitled to the Subscriber’s or its designee’s balance account with DTC through its Deposit/Withdrawal
at Custodian system or (B) if the Company’s transfer agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver (via reputable overnight courier) to the Subscriber, a certificate representing such

approved the Securities or passed upon or endorsed the merits of the Offering. There is no government or other insurance covering any of the Securities. 

(k) The Subscriber and its Advisors, if any, have had a reasonable opportunity to ask questions of and receive answers from a person or
persons acting on behalf of the Company concerning the Offering and the business, financial condition, results of operations and prospects of the Company, and all such questions have been answered to the full satisfaction of the Subscriber and its
Advisors, if any. 
 (l) (i) In making the decision to invest in the Securities the Subscriber has relied solely upon the information
provided by the Company in the Transaction Documents. To the extent necessary, the Subscriber has 

  
 - 7 - 








 
retained, at its own expense, and relied upon appropriate professional advice regarding the investment, tax and legal merits and consequences of this Agreement and the purchase of the Securities
hereunder. The Subscriber disclaims reliance on any statements made or information provided by any person or entity in the course of Subscriber’s consideration of an investment in the Securities other than the Transaction Documents. 

(ii) The Subscriber represents and warrants that: (i) the Subscriber was contacted regarding the sale of the Securities by the Company
(or an authorized agent or representative thereof) with whom the Subscriber had a prior substantial pre-existing relationship and (ii) no Securities were offered or sold to it by means of any form of general solicitation or general advertising,

circuit, or generally available; or (B) attend any seminar meeting or industry investor conference whose attendees were invited by any general solicitation or general advertising; or (C) observe any website or filing of the Company with
the SEC in which any offering of securities by the Company was described and as a result learned of any offering of securities by the Company. 

(m) The Subscriber has taken no action that would give rise to any claim by any person for brokerage commissions, finders’ fees or the
like relating to this Agreement or the transactions contemplated hereby. 
 (n) The Subscriber is not relying on the Company or any of its
employees, agents, or advisors with respect to the legal, tax, economic and related considerations of an investment in the Securities, and the Subscriber has relied on the advice of, or has consulted with, only its own Advisors. 

(o) The Subscriber acknowledges that any estimates or forward-looking statements or projections furnished by the Company to the Subscriber
were prepared by the management of the Company in good faith, but that the attainment of any such projections, estimates or forward-looking statements cannot be guaranteed by the Company or its management and should not be relied upon. 

(p) No oral or written representations have been made, or oral or written information furnished, to the Subscriber or its Advisors, if any, in
connection with the Offering that are in any way inconsistent with the information contained herein. 
 (q) (For ERISA plans only) The
fiduciary of the ERISA plan (the “Plan”) represents that such fiduciary has been informed of and understands the Company’s investment objectives, policies and strategies, and that the decision to invest “plan assets” (as
such term is defined in ERISA) in the Company is consistent with the provisions of ERISA that require diversification of plan assets and impose other fiduciary responsibilities. The Subscriber or Plan fiduciary (i) is responsible for the
decision to invest in the Company; (ii) is independent of the Company and any of its affiliates; (iii) is qualified to make such investment decision; and (iv) in making such decision, the Subscriber or Plan fiduciary has not relied

Subscriber unless it has been accepted by the Company, and the Subscriber acknowledges and agrees that the Company reserves the right to reject any subscription for any reason. 

(s) The Subscriber is an “Accredited Investor” as defined in Rule 501(a) under the Securities Act. In general, an “Accredited
Investor” is deemed to be an institution with assets in excess of $5,000,000 or individuals with a net worth in excess of $1,000,000 (excluding such person’s residence) or annual income exceeding $200,000 or $300,000 jointly with his or
her spouse. 
 (t) The Subscriber, 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 Offering, and has so evaluated the merits and risks of such investment. The Subscriber has not authorized any person or entity to act as its Purchaser
Representative (as that term is defined in Regulation D of the General Rules and Regulations under the Securities Act) in connection with the Offering. The Subscriber 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.

qualified as a foreign entity to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to
be so qualified or be in good standing would not have a Material Adverse Effect. As used in this Agreement, “Material Adverse Effect” means any material adverse effect on (i) the business, properties, assets, liabilities,
operations (including results thereof), condition (financial or otherwise) or prospects of the Company or any Subsidiary, either individually or taken as a whole, (ii) the transactions contemplated hereby or in any of the other Transaction
Documents or (iii) the authority or ability of the Company or any of its Subsidiaries to perform any of their respective obligations under any of the Transaction Documents. Other than as set forth on Schedule 4(a), the Company has no

or any part of the business, operations or administration of such Person, and each of the foregoing, is individually referred to herein as a “Subsidiary.” 

(b) Authorization; Enforcement; Validity 

The Company has the requisite power and authority to enter into and perform its obligations under this Agreement and the other Transaction
Documents and to issue the Securities in accordance with the terms hereof and thereof. Each Subsidiary has the requisite power and authority to enter into and perform its obligations under the Transaction Documents to which it is a party. The
execution and delivery of this Agreement and the other Transaction Documents by the Company, and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Shares, the
Preferred Shares, the Warrants and the reservation for issuance and issuance of the Conversion Shares and Warrant Shares issuable upon conversion and exercise of the Preferred Shares and Warrants, respectively) have been duly authorized by the
Company’s board of directors and each of its Subsidiaries’ board of directors or other governing body, as applicable, and (other than (i) the filing with the SEC of a Form D under Regulation D of the Securities Act (ii) the
8-K Filing (as defined below), (iii) any action necessary in order to qualify the Securities, and any other filings as may be required by any state securities agencies or “Blue Sky” laws of the states of the United States, and
(iv) if applicable, the listing of the Shares, the Conversion Shares and the Warrant Shares on the Principal Market (as defined below)) no further filing, consent or authorization is required by the Company, its Subsidiaries, their respective
boards of directors or their stockholders or other governing body. This Agreement has been, and the other Transaction Documents will be, prior to the Closing, duly executed and delivered by the Company, and each constitutes the legal, valid and
binding obligations of the Company, enforceable against the Company in accordance with its respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization,

law.

authorized capital stock not less than 125% of the maximum number of shares of Common Stock issuable upon conversion of the Preferred Shares (assuming for purposes hereof that the Preferred Shares are convertible at the initial Conversion Price (as
defined in the Certificate of Designations) and upon exercise of the Warrants and without taking into account any limitations on the conversion of such Preferred

Shares set forth in the Certificate of Designations or the Warrants). The issuance of the Securities are duly authorized, and upon issuance in accordance with the applicable Transaction
Documents, will be validly issued, fully paid and non-assessable and free from all preemptive or similar rights, taxes, liens, charges and other encumbrances with respect to the issue thereof, with the holders being entitled to all rights accorded
to a holder of Common Stock. Subject to the accuracy of the representations and warranties of the Subscribers in this Agreement, the offer and issuance by the Company of the Securities is exempt from registration under the Securities Act. 

(d) No Conflicts 
 The
execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Shares, the Preferred Shares,

to the Company or any of its Subsidiaries or by which any property or asset of the Company or any of its Subsidiaries is bound or affected other than, in the case of clause (ii) above, such conflicts, defaults or rights that could not
reasonably be expected to have a Material Adverse Effect. 
 (e) Consents 

Neither the Company nor any Subsidiary is required to obtain any consent from authorization or order of, or make any filing or registration
with (other than the filing with the SEC of a Form D and any other filings as may be required by any state securities agencies) any court, governmental agency or any regulatory or self-regulatory agency or any other Person in order for it to
execute, deliver or perform any of its respective obligations under, or contemplated by, the Transaction Documents, in each case, in accordance with the terms hereof or thereof. All consents, authorizations, orders, filings and registrations which
the Company is required to obtain at or prior to the Closing have been obtained or effected on or prior to each Closing Date, and neither the Company nor any of its Subsidiaries are aware of any facts or circumstances which might prevent the Company
from obtaining or effecting any of the registration, application or filings contemplated by the Transaction Documents. The Company is not in violation of the requirements of the Principal Market and has no knowledge of any facts or circumstances
which could reasonably lead to delisting or suspension of the Common Stock in the foreseeable future.

 (g) No General Solicitation; Placement Agent’s Fees 

Neither the Company, nor any of its Subsidiaries or affiliates, nor any Person acting on its or their behalf, has engaged in any form of
general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale of the Securities. The Company shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or
brokers’ commissions (other than for Persons engaged by any Subscriber or its investment advisor) relating to or arising out of the transactions contemplated hereby. Other than the Placement Agent or other than as set forth on Schedule
4(g), neither the Company nor any of its Subsidiaries has engaged any placement agent or other agent in connection with the offer or sale of the Securities. 

(h) No Integrated Offering 

None of the Company, its Subsidiaries or any of their affiliates, nor any Person acting on 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 require registration of the issuance of any of the Securities under the Securities Act, whether through integration with prior offerings or
otherwise, or cause this offering of the Securities to require approval of stockholders of the Company under any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated
quotation system on which any of the securities of the Company are listed or designated for quotation. None of the Company, its Subsidiaries, their affiliates nor any Person acting on their behalf will take any action or steps that would require

Company understands and acknowledges that the number of Shares, Conversion Shares and Warrant Shares will increase in certain circumstances. The Company further acknowledges that its obligation to issue the Securities in accordance with this
Agreement, the Conversion Shares upon conversion of the Preferred Shares in accordance with the Certificate of Designations and the Warrant Shares in accordance with the terms of 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.

Protections; Rights Agreement 
 The Company and its board of directors have taken all necessary action, if any, in order to render
inapplicable any control share acquisition, interested stockholder, business combination, poison pill (including, without limitation, any distribution under a rights agreement), stockholder rights plan or other similar anti-takeover provision under
the Charter, Bylaws or other organizational documents or the laws of the jurisdiction of its incorporation or otherwise which is or could become applicable to any Subscriber as a result of the transactions contemplated by this Agreement, including,
without limitation, the Company’s issuance of the Securities and any Subscriber’s ownership of the Securities. The Company and its board of directors have taken all necessary action, if any, in order to render inapplicable any stockholder

Except as disclosed on Schedule 4(k), true, correct and complete copies of each of the SEC Documents are available on the EDGAR system. As of their respective dates, except as described on Schedule 4(k), the SEC Documents complied in
all material respects with the requirements of the Exchange Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC 

  
 - 11 - 








 
Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company included in the SEC Documents complied in all material respects with
applicable accounting requirements and the published rules and regulations of the SEC with respect thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with generally accepted accounting
principles, consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in
the case of unaudited statements, to normal year-end audit adjustments which will not be material, either individually or in the aggregate). No other information provided by or on behalf of the Company by its authorized agents to any of the
Subscribers which is not included in the SEC Documents contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein not misleading, in the light of the circumstance under
which they are or were made. 
 (l) Absence of Certain Changes 

Since the date of the Company’s most recent audited financial statements contained in the Current Report on Form 8-K/A filed on

operations (including results thereof), condition (financial or otherwise) or prospects of the Company or any of its Subsidiaries. Since the date of the Company’s most recent audited financial statements contained in the September 8-K,
neither the Company nor any of its Subsidiaries has (i) declared or paid any dividends, (ii) sold any assets, individually or in the aggregate, outside of the ordinary course of business or (iii) made any material capital
expenditures, individually or in the aggregate, outside of the ordinary course of business. Neither the Company nor any of its Subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency,
reorganization, receivership, liquidation or winding up, nor does the Company or any Subsidiary have any knowledge or reason to believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual
knowledge of any fact which would reasonably lead a creditor to do so. The Company and its Subsidiaries, individually and on a consolidated basis, are not as of the date hereof, and after giving effect to the transactions contemplated hereby to
occur at the Closing will not be, Insolvent (as defined below), subject to the qualifications and assumptions set forth in the going concern disclosure in the SEC Documents. For purposes of this Section, “Insolvent” means, as of the
date of Closing (I) with respect to the Company and its Subsidiaries, on a consolidated basis, (i) the present fair saleable value of the Company’s and its Subsidiaries’ assets is less than the amount required to pay the
Company’s and its Subsidiaries’ total Indebtedness (as defined below), (ii) the Company and its Subsidiaries are unable to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become
absolute and matured or (iii) the Company and its Subsidiaries intend to incur or believe that they will incur debts that would be beyond their ability to pay as such debts mature; and (II) with respect to the Company and each Subsidiary,
individually, (i) the present fair saleable value of the Company’s or such Subsidiary’s (as the case may be) assets is less than the amount required to pay its respective total Indebtedness, (ii) the Company or such Subsidiary
(as the case may be) is unable to pay its respective debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured or (iii) the Company or such Subsidiary (as the case may be) intends to
incur or believes that it will incur debts that would be beyond its respective ability to pay as such debts mature. Neither the Company nor any of its Subsidiaries has engaged in any business or in any transaction, and is not about to engage in any
business or in any transaction, for which the Company’s or such Subsidiary’s remaining assets constitute unreasonably small capital. 

(m) No Undisclosed Events, Liabilities, Developments or Circumstances 

Other than the transactions contemplated hereby, no event, liability, development or circumstance has occurred or exists, or is reasonably
expected to occur or exist, with respect to the Company, any of its Subsidiaries or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition (financial or otherwise) that
(i) would be required to be disclosed by the Company under applicable securities laws on a registration statement on Form S-1 filed with the SEC relating to an issuance and sale by the Company of its Common Stock and which has not been publicly
announced, (ii) would reasonably be expected have a material adverse effect on any Subscriber’s investment hereunder or (iii) could have a Material Adverse Effect.

respectively. Neither the Company nor any of its Subsidiaries is in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to the Company or any of its Subsidiaries, and neither the Company nor any of its
Subsidiaries will conduct its business in violation of any of the foregoing, except in all cases for possible violations which could not, individually or in the aggregate, have a Material Adverse Effect. Without limiting the generality of the
foregoing, the Company is not in violation of any of the rules, regulations or requirements of the Principal Market and has no knowledge of any facts or circumstances that could reasonably lead to delisting or suspension of the Common Stock by the
Principal Market in the foreseeable future. Except as set forth on Schedule 4(n), since 2010, (i) the Common Stock has been listed or designated for quotation on the Principal Market, (ii) trading in the Common Stock has not been
suspended by the SEC or the Principal Market and (iii) the Company has received no communication, written or oral, from the SEC or the Principal Market regarding the suspension or delisting of the Common Stock from the Principal Market. The
Company and each of its Subsidiaries possess all certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates,
authorizations or permits would not have, individually or in the aggregate, a Material Adverse Effect, and neither the Company nor any such Subsidiary has received any notice of proceedings relating to the revocation or modification of any such
certificate, authorization or permit.

Neither the Company nor any of its Subsidiaries nor any director, officer, agent, employee or other Person acting on behalf of the Company or

suspending the effectiveness of any registration statement filed by the Company under the Securities Act or the Exchange Act. 
 (u)
Insurance 
 The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such
losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any
insurance coverage sought or applied for, and neither the Company nor any such Subsidiary has any reason to believe that it will be unable to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

of its Subsidiaries has notified the Company or any such Subsidiary that such officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s employment with 

  
 - 15 - 








 
the Company or any such Subsidiary. No executive officer or other key employee of the Company or any of its Subsidiaries is, or is now expected to be, in violation of any material term of any
employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer or other
key employee (as the case may be) does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all federal, state, local and foreign
laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably
be expected to result in a Material Adverse Effect. 
 (w) Title

personal property, owned by them which is material to the business of the Company and its Subsidiaries, in each case, free and clear of all liens, encumbrances and defects except such as do not materially affect the value of such property and do not
interfere with the use made of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company or any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with
such exceptions as are not material and do not interfere with the use made of such property and buildings by the Company or any of its Subsidiaries. 

(x) Intellectual Property Rights 

The Company and its Subsidiaries own or possess adequate rights or licenses to use all trademarks, trade names, service marks, service mark

Subscriber 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 date hereof pursuant to the Exchange
Act. As long as any Subscriber owns Securities, if the Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Subscribers and make publicly available in accordance with Rule 144(c) under the
Securities Act such information as is required for the Subscribers to sell the Securities under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, at the sole cost and
expense of the Company including transfer agent and legal opinion fees and expenses, all to the extent required from time to time to enable such person to sell such Securities without registration under the Securities Act within the limitation of
the exemptions proved by Rule 144 under the Securities Act. 
 (b) Shareholder Rights Plan. No claim will be made or enforced by the
Company or, to the knowledge of the Company, any other person that any Subscriber is an “Acquiring Person” under any shareholder rights plan or similar plan or arrangement in effect or hereafter adopted by the Company, or that any
Subscriber 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 the Subscribers. 

(c) Securities Laws Disclosure; Publicity. The Company shall by 8:30 a.m. (New York City time) (a) on the first Business Day after
this Agreement has been executed, issue a press release disclosing the material terms of the transactions contemplated hereby and (b) within four (4) Business Days after this Agreement has been executed, file a Current Report on Form 8-K
with the SEC (the “8-K Filing”), including the Transaction Documents as exhibits thereto. From and after the issuance of such press release and the 8-K Filing, the Company shall have publicly disclosed all material, non-public
information delivered to any of the Subscribers by the Company or any of its Subsidiaries, or any of their respective officers, directors, employees or agents. The Company and each Subscriber shall consult with each other in issuing any press
releases with respect to the transactions contemplated hereby, and no Subscriber shall issue any such press release or otherwise make any such public statement without the prior consent of the Company, which consent shall not unreasonably be
withheld. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Subscriber, or include the name of any 

  
 - 20 - 








 
Subscriber in any filing with the SEC or any regulatory agency, without the prior written consent of such Subscriber, except to the extent such disclosure is required by law or in connection with
the Registration Rights of the Company set forth in Section 7 herein, in which case the Company shall provide the Subscribers with prior notice of such disclosure. The Company understands that any such disclosure shall cause irreparable harm
and each Subscriber shall be entitled to injunctive relief and liquidated damages in connection therewith. 
 (d) Integration. The
Company shall not, and shall use its best efforts to ensure that no affiliate of the Company shall, after the date hereof, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security that would be integrated with
the offer or sale of the Units in a manner that would require the registration under the Securities Act of the sale of the Units to the Subscribers. 

(e) Reservation of Securities. 

(i) 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 then be required to fulfill its obligations in full under the Transaction Documents, but not less than 125% of the maximum number of shares of Common Stock issuable pursuant to the Transaction Documents (the “Required
Minimum”). 
 (ii) If, on any date, the number of authorized but unissued (and otherwise unreserved) shares of Common Stock is less
than the Required Minimum on such date, then the Board of Directors shall approve the amendment of the Company’s Charter to increase the number of authorized but unissued shares of Common Stock to at least the Required Minimum and submit such
amendment to the Company’s stockholders for approval, as soon as possible and in any event not later than the 60th day after such date. 

(iii) The Company shall, if applicable: (i) in the time and manner required by the Principal Market, prepare and file with such Principal
Market an additional shares listing application covering a number of shares of Common Stock at least equal to the Required Minimum on the date of such application, (ii) take all steps necessary to cause such shares of Common Stock to be
approved for listing or quotation on such Principal Market as soon as possible thereafter, (iii) provide to the Subscribers evidence of such listing or quotation and (iv) maintain the listing or quotation of such Common Stock on any date
at least equal to the Required Minimum on such date on such Principal Market or another Principal Market. The Company will then take all commercially reasonable action necessary to continue the listing or quotation and trading of its Common Stock on
a Principal Market for as long as any Subscriber holds Securities, and will comply in all material respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Principal Market at least until five years
after the Closing Date. In the event the aforedescribed listing is not continuously maintained for five years after the Closing Date (a “Listing Default”), then in addition to any other rights the Subscribers may have hereunder or
under applicable law, on the first day of a Listing Default and on each monthly anniversary of each such Listing Default date (if the applicable Listing Default shall not have been cured by such date) until the applicable Listing Default is cured,
the Company shall pay to each Subscriber an amount in cash, as partial liquidated damages and not as a penalty, equal to 1% of (x) aggregate Subscription Amount of Shares or Conversion Shares calculated on an “as converted” basis, as
the case may be held by such Subscriber on the date of a Listing Default and (y) the aggregate purchase price of Warrant Shares held by such Subscriber on the day of a Listing Default and on every thirtieth day (pro-rated for periods less than
thirty days) thereafter with respect to Shares (or “as converted” Conversion Shares”) and Warrant Shares held as of each such date until the date such Listing Default is cured or Subscriber no longer holds any Shares, Preferred
Shares, Conversion Shares or Warrant Shares. 
 (f) Use of Proceeds. The Company anticipates using the gross proceeds from the
Offering as set forth on Exhibit D or for such other purposes as may be approved in writing by Subscribers representing the Required Approval. 

(g) Non-Public Information. Except with respect to the material terms and conditions of the transactions contemplated by the
Transaction Documents, the Company covenants and agrees that neither it, nor any other Person acting on its behalf will provide any Subscriber or its agents or counsel with any information that the Company believes constitutes or could constitute
material non-public information, and each Subscriber agrees, and shall direct its agents and counsel not to, request any material non-public information from the Company or any Person acting on its behalf, unless prior thereto such Subscriber shall
have executed a written agreement with the 

  
 - 21 - 








 
Company regarding the willingness to accept receipt of such material non-public information and acknowledges the confidentiality and use of such information and the Company’s covenant to
file a further SEC filing or report and the period in which such information shall remain confidential or be required to not be disclosed. The Company understands and confirms that each Subscriber shall be relying on the foregoing covenant in
effecting transactions in securities of the Company. In addition, effective upon the filing of the 8-K Filing, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral,
between the Company and any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents, on the one hand, and the Subscriber or any of its affiliates on the other hand, shall terminate. 

(h) Right of Participation. The Company acknowledges and agrees that the right set forth in this Section 5(h) is a right granted
by the Company, separately, to each Subscriber. 
 (i) At least five (5) trading days prior to any proposed or intended sale by the
Company of its Common Stock or other securities or equity linked debt obligations (each, a “Subsequent Placement”), the Company shall deliver to each Subscriber a written notice of its proposal or intention to effect a Subsequent
Placement (each such notice, a “Pre-Notice”), which Pre-Notice shall not contain any information (including, without limitation, material, non-public information) other than: (A) a statement that the Company proposes or intends
to effect a Subsequent Placement, (B) a statement that the statement in clause (A) above does not constitute material, non-public information and (C) a statement informing such Subscriber that it is entitled to receive an Offer Notice
(as defined below) with respect to such Subsequent Placement upon its written request. Upon the written request of a Subscriber within five (5) business days after the Company’s delivery to such Subscriber of such Pre-Notice, and only upon
a written request by such Subscriber, the Company shall promptly, but no later than one (1) business day after such request, deliver to such Subscriber an irrevocable written notice (the “Offer Notice”) of any proposed or
intended issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered Securities”) in a Subsequent Placement, which Offer Notice shall (I) identify and describe the Offered
Securities, (II) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (III) identify the persons (if known) to which or with which
the Offered Securities are to be offered, issued, sold or exchanged and (IV) offer to issue and sell to or exchange with such Subscriber in accordance with the terms of the Offer such Subscriber’s pro rata portion of 100% of the Offered
Securities, provided that the number of Offered Securities which such Subscriber shall have the right to subscribe for under this Section 5(h) shall be (x) based on such Subscriber’s pro rata portion of the aggregate original amount
of the Units purchased hereunder by all Subscribers (the “Basic Amount”), and (y) with respect to each Subscriber that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the
Basic Amounts of other Subscribers as such Subscribers shall indicate it will purchase or acquire should the other Subscribers subscribe for less than their Basic Amounts (the “Undersubscription Amount”). 

(ii) To accept an Offer, in whole or in part, such Subscriber must deliver a written notice to the Company prior to the end of the fifth (5th) Business Day after such Subscriber’s receipt of the Offer Notice (the “Offer Period”), setting forth the portion of such Subscriber’s Basic Amount that such
Subscriber elects to purchase and, if such Subscriber shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Subscriber elects to purchase (in either case, the “Notice of Acceptance”). If
the Basic Amounts subscribed for by all Subscribers are less than the total of all of the Basic Amounts, then such Subscriber who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the
Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed
for (the “Available Undersubscription Amount”), such Subscriber who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of
such Subscriber bears to the total Basic Amounts of all Subscribers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent it deems reasonably necessary. Notwithstanding the foregoing, if the Company
desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company may deliver to each Subscriber a new Offer Notice and the Offer Period shall expire on the fifth (5th) Business Day after such Subscriber’s receipt of such new Offer Notice. 

(iii) The Company shall have five (5) Business Days from the expiration of the Offer Period above (A) to offer, issue, sell or
exchange all or any part of such Offered Securities as to which a Notice of 

  
 - 22 - 








 
Acceptance has not been given by a Subscriber (the “Refused Securities”) pursuant to a definitive agreement(s) (the “Subsequent Placement Agreement”), but only
to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less
favorable to the Company than those set forth in the Offer Notice and (B) to publicly announce (I) the execution of such Subsequent Placement Agreement, and (II) either (x) the consummation of the transactions contemplated by such
Subsequent Placement Agreement or (y) the termination of such Subsequent Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated therein
filed as exhibits thereto. 
 (iv) In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be
in the manner and on the terms specified in Section 5(h)(iii) above), then such Subscriber may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an
amount that shall be not less than the number or amount of the Offered Securities that such Subscriber elected to purchase pursuant to Section 5(h)(ii)1(a)(ii) above multiplied by a fraction, (A) the numerator of which shall be the number
or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Subscribers pursuant to this Section 5(h) prior to such reduction) and (B) the denominator of
which shall be the original amount of the Offered Securities. In the event that any Subscriber so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more
than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Subscribers in accordance with Section 5(h)(i) above. 

(v) Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Subscriber shall acquire from
the Company, and the Company shall issue to such Subscriber, the number or amount of Offered Securities specified in its Notice of Acceptance. The purchase by such Subscriber of any Offered Securities is subject in all cases to the preparation,
execution and delivery by the Company and such Subscriber of a separate purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to such Subscriber and its counsel. 

(vi) Any Offered Securities not acquired by a Subscriber or other persons in accordance with this Section 5(h) may not be issued, sold or
exchanged until they are again offered to such Subscriber under the procedures specified in this Agreement. 
 (vii) The Company and each
Subscriber agree that if any Subscriber elects to participate in the Offer, neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction documents related thereto (collectively, the “Subsequent Placement
Documents”) shall include any term or provision in addition to any terms or conditions contained in this Agreement whereby such Subscriber shall be required to agree to any restrictions on trading as to any securities of the Company or be
required to consent to any amendment to or termination of, or grant any waiver, release or the like under or in connection with, any agreement previously entered into with the Company or any instrument received from the Company. 

(viii) Notwithstanding anything to the contrary in this Section 5(h) and unless otherwise agreed to by such Subscriber, the Company shall
either confirm in writing to such Subscriber that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case, in such a manner such that such
Subscriber will not be in possession of any material, non-public information, by the fifth (5th) business day following delivery of the Offer Notice. If by such fifth (5th) business day, no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such transaction has been received
by such Subscriber, such transaction shall be deemed to have been abandoned and such Subscriber shall not be in possession of any material, non-public information with respect to the Company or any of its subsidiaries. Should the Company decide to
pursue such transaction with respect to the Offered Securities, the Company shall provide such Subscriber with another Offer Notice in accordance with, and subject to, the terms of this Section 5(h) and such Subscriber will again have the right
of participation set forth in this Section 5(h) The Company shall not be permitted to deliver more than one such Offer Notice to such Subscriber in any sixty (60) day period, except as expressly contemplated by the last sentence of
Section 5(h)(ii).

month anniversary of the Closing Date. 
 (k) Capital Changes. Until the one year anniversary of the Final Closing Date, the Company

securities exchange or maintaining compliance with such listing. 
 (l) DTC Program. From the Closing Date until such time as no
Subscriber holds any of the Securities (such date, the “Release Date”), the Company shall use its best efforts to employ as the transfer agent for the Common Stock, the Conversion Shares and Warrant Shares a participant in the
Depository Trust Company Automated Securities Transfer Program (FAST) and cause the Common Stock to be transferable pursuant to such program. 

(j) Equity Incentive Plan. Within thirty (30) days of the Closing Date, the Company’s Board of Directors will approve amend
and restate the Company’s existing stock option plan such that there will be resrved for issuance thereunder 7,116,204 shares of Common Stock. The Company will use its reasonable best efforts to cause its stockholders to ratify the amendment

requirement. The Company shall, on or before the Closing Date, take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to, qualify the Securities for sale to the Subscribers at the Closing

costs and expenses whatsoever reasonably incurred in investigating, preparing or defending against any claim, lawsuit, administrative proceeding or investigation whether commenced or threatened) (the “Indemnified Liabilities”), incurred by

each of the Indemnified Liabilities which is permissible under applicable law. 
 (t) Fees. The Company shall reimburse Sichenzia Ross

 - 25 - 








 (i) As of the Closing, no legal action, suit or proceeding shall be pending against the Company
that seeks to restrain or prohibit the transactions contemplated by this Agreement. 
 (ii) The representations and warranties of the
Company and the Subscribers contained in this Agreement shall have been true and correct in all material respects on the date of this Agreement and shall be true and correct as of the Closing as if made on the Closing Date. 

7. REGISTRATION RIGHTS. The Company shall file a “resale” registration statement with the SEC covering 25% of the Shares (or
Conversion Shares) purchased by the Subscriber, so that such shares of Common Stock will be registered under the Securities Act. The Company will maintain the effectiveness of the “resale” registration statement from the effective date of
the registration statement until all Registrable Securities (as defined in the Registration Rights Agreement) covered by such registration statement have been sold, or may be sold without the requirement to be in compliance with Rule 144(c)(1) and
otherwise without restriction or limitation pursuant to Rule 144. The Company will use its reasonable best efforts to have such “resale” registration statement filed by the Filing Date (as defined in the Registration Rights Agreement) and
declared effective by the SEC as soon as possible and, in any event, by the Effectiveness Date (as defined in the Registration Rights Agreement), unless extended by Subscribers representing the Required Approval. 

The Company is obligated to pay to the Subscribers a fee of 1% per month of the investors’ investment, payable in cash, up to a
maximum of twelve (12%) percent, on the Filing Date and the Effectiveness Date if the registration obligations set forth herein have not been met, and pro- rata for each month, or partial month, in excess of the Filing Date and/or the
Effectiveness Date that the registration statement has not been declared effective; provided, however, that the Company shall not be obligated to pay any such liquidated damages if the Company is unable to fulfill its registration obligations as a
result of rules, regulations, positions or releases issued or actions taken by the SEC pursuant to its authority with respect to “Rule 415”, provided the Company registers at such time the maximum number of shares of Common Stock
permissible upon consultation with the staff of the SEC. 
 The description of registration rights is qualified in its entirety by reference
to Registration Rights Agreement annexed hereto as Exhibit E (the “Registration Rights Agreement”). 
  

	8.	MISCELLANEOUS PROVISIONS 

 (a) All parties hereto have been represented by counsel, and
no inference shall be drawn in favor of or against any party by virtue of the fact that such party’s counsel was or was not the principal draftsman of this Agreement. 

(b) Each of the parties hereto shall be responsible to pay the costs and expenses of its own legal counsel in connection with the preparation

communication hereunder to the Subscriber at the address set forth on the signature page of this Agreement or to the Company at its primary office (including personal delivery, expedited courier, messenger service, fax, ordinary mail or electronic

claims and other communications hereunder are to be delivered by giving the other parties written notice in the manner herein set forth. 

(f) Except as otherwise provided herein, this Agreement shall be binding upon, and inure to the benefit of, the parties to this Agreement and
their heirs, executors, administrators, successors, legal representatives

and assigns. If any Subscriber is more than one person or entity, the obligation of any Subscriber shall be joint and several and the agreements, representations, warranties and acknowledgments
contained herein shall be deemed to be made by, and be binding upon, each such person or entity and its heirs, executors, administrators, successors, legal representatives and assigns. This Agreement sets forth the entire agreement and understanding
between the parties as to the subject matter hereof and merges and supersedes all prior discussions, agreements and understandings of any and every nature among them. 

(g) This Agreement is not transferable or assignable by the Company. 

(h) The Company hereby represents and warrants as of the date hereof and as of any Closing Date that none of the terms offered to any Person
with respect to any offer, sale or subscription of Securities (each a “Subscription Document”), is or will be more favorable to such Person than those of the Subscriber and this Agreement shall be, without any further action by the
Subscriber or the Company, deemed amended and modified in an economically and legally equivalent manner such that the Subscriber shall receive the benefit of the more favorable terms contained in such Subscription Document. Notwithstanding the
foregoing, the Company agrees, at its expense, to take such other actions (such as entering into amendments to the Transaction Documents) as the Subscriber may reasonably request to further effectuate the foregoing. 

(i) Except as otherwise provided herein, this Agreement shall not be changed, modified or amended and no right hereunder shall be waived,
except in writing signed by both (a) the Company and (b) Subscribers representing the Required Approval. The Company shall be prohibited from offering any additional consideration to any Subscriber in this Offering (or such original
Subscriber’s transferee) for the purposes of inducing such person to change, modify, waive or amend any term of this Agreement or any other Transaction Document without making the same offer on a pro-rata basis to all other Subscribers (and
those transferees) in this Offering allocable to the securities acquired by such transferee(s). 
 (j) This Agreement shall be governed by
and construed in accordance with the laws of the State of New York, without giving effect to conflicts of law principles. 
 (k) The Company

to the sale of the securities hereunder, and consent to the service of process in any such action or legal proceeding by means of registered or certified mail, return receipt requested, postage prepaid, in care of the address set forth herein or
such other address as either party shall furnish in writing to the other. 
 (l) WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING
IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY
JURY. 
 (m) This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.
