 SERIES K 18% CUMULATIVE CONVERTIBLE PREFERRED STOCK

of Series K Preferred Stock shall be 30,000. Each share of Series K Preferred Stock shall have a stated value equal to $100 (as adjusted for any stock dividends, combinations or splits with respect to such shares) (the “Stated Value”), and
$1.00 par value. The Corporation will not issue more than 30,000 shares of Series K Preferred Stock (“Original Issue”). 
 2.
Dividends. 
 (a) The Holders of outstanding shares of Series K Preferred Stock (“Holders”) shall be entitled to receive
preferential dividends in cash out of any funds of the Corporation before any dividend or other distribution will be paid or declared and set apart for payment on any shares of any Common Stock, or other class of stock presently authorized or to be
authorized, except for the Corporation’s Series A Preferred Stock, which has an aggregate stated value of $21,500 and pays an annual dividend aggregating to $2,150, (the Common Stock, and such other stock being hereinafter collectively the
“Junior Stock”) at the rate of 18% per annum on the Stated Value, payable in cash on the earlier of (i) quarterly in arrears commencing July 11, 2007 and quarterly thereafter in cash or (ii) upon redemption, as
hereinafter provided, following the closing of any subsequent financing (whether done in one or more financings of debt and/or equity) by the Company with gross proceeds equal to or greater than $6,000,000. To the extent not prohibited by law,
dividends must be paid to the Holders not later than five (5) business days after the end of each period for which dividends are payable. 

 (b) The dividends on the Series K Preferred Stock, at the rates provided above, shall be cumulative
whether or not declared so that, if at any time full cumulative dividends at the rate aforesaid on all shares of the Series K Preferred Stock then outstanding, from the date from and after which dividends thereon are cumulative to the end of the
annual dividend period next preceding such time shall not have been paid or declared and set apart for payment, or if the full dividend on all such outstanding Series K Preferred Stock for the then current dividend period shall not have been paid or
declared and set apart for payment, the amount of the deficiency shall be paid or declared and set apart for payment before any sum shall be set apart for or applied by the Corporation or a subsidiary of the Corporation to the purchase, redemption
or other acquisition of the Series K Preferred Stock or any shares of any other class of stock ranking on a parity with the Series K Preferred Stock and before any dividend or other distribution shall be paid or declared and set apart for payment on
any Junior Stock and before any sum shall be set aside for or applied to the purchase, redemption or other acquisition of Junior Stock. 
 (c) Dividends on all shares of the Series K Preferred Stock shall begin to accrue and be cumulative from and after the date of issuance thereof. A dividend period shall be deemed to commence on the day following a dividend payment date
herein specified and to end on the next succeeding dividend payment date herein specified. 
 3. Liquidation. 
 (a) Upon the dissolution, liquidation or winding-up of the Corporation, whether voluntary or involuntary, the Holders of the Series K Preferred Stock
shall be entitled to receive before any payment or distribution shall be made on Junior Stock, out of the assets of the Corporation available for distribution to stockholders, the Stated Value per share of Series K Preferred Stock and all accrued
and unpaid dividends to and including the year-end of the year of redemption. Upon the payment in full of all amounts due to Holders of the Series K Preferred Stock, the holders of the Common Stock of the Corporation and any other class of Junior
Stock shall receive all remaining assets of the Corporation legally available for distribution. If the assets of the Corporation available for distribution to the Holders of the Series K Preferred Stock shall be insufficient to permit payment in
full of the amounts payable as aforesaid to the Holders of Series K Preferred Stock upon such liquidation, dissolution or winding-up, whether voluntary or involuntary, then all such assets of the Corporation shall be distributed to the exclusion of
the holders of shares of Junior Stock ratably among the Holders of the Series K Preferred Stock. 
 (b) The purchase or the redemption by the
Corporation of shares of any class of stock, the merger or consolidation of the Corporation with or into any other corporation or entity, or the sale or transfer by the Corporation of substantially all of its assets shall be deemed to be a
liquidation, dissolution or winding-up of the Corporation for the purposes of this Section 3. 
 4. Conversion into Common Stock.
Holders of shares of Series K Preferred Stock shall have the following conversion rights and obligations: 
 (a) Subject to the further
provisions of this Section 4, each Holder of shares of Series K Preferred Stock shall have the right at any time commencing after the issuance to the Holder of Series K Preferred Stock, to convert such shares, accrued and unpaid dividends on
such shares, and any other sum owed by the Corporation arising from the Series K Preferred Stock or pursuant to a subscription agreement entered into by the Corporation and the Holder in connection with the issuance of Series K Preferred Stock
(“Subscription Agreement”) (collectively “Obligation Amount”) into fully paid and non-assessable shares of Common Stock of the Corporation determined in accordance with the Conversion Price provided in Section 4(b) below
(the “Conversion Price”). All issued or accrued but unpaid dividends may be converted at the election of the Holder simultaneously with the conversion of principal amount of Stated Value of Series K Preferred Stock being converted at $0.10
per share. 
  

 2 

 (b) The number of shares of Common Stock issuable upon conversion of the Obligation Amount shall equal
(i) the sum of (A) the Stated Value per share being converted, (B) at the Holder’s election, accrued and unpaid dividends on such share, and (C) at the Holder’s election, any other sum owed by the Corporation to the
Holder arising from any source including, but not limited to, the Series K Preferred Stock or Subscription Agreement divided by (ii) the Conversion Price. The Conversion Price shall be $0.10, subject to adjustment as described herein and in the
Subscription Agreement. 
 (c) Holder will give notice of its decision to exercise its right to convert the Series K Preferred Stock or part
thereof by telecopying an executed and completed Notice of Conversion (a form of which is annexed as Exhibit A to the Certificate of Amendment) to the Corporation via confirmed telecopier transmission or otherwise pursuant to Section 12(a) of
the Subscription Agreement. The Holder will not be required to surrender the Series K Preferred Stock certificate until the Series K Preferred Stock has been fully converted. Each date on which a Notice of Conversion is telecopied to the Corporation
in accordance with the provisions hereof shall be deemed a Conversion Date. The Corporation will itself or cause the Corporation’s transfer agent to transmit the Corporation’s Common Stock certificates representing the Common Stock
issuable upon conversion of the Series K Preferred Stock to the Holder via express courier for receipt by such Holder within three (3) business days after receipt by the Corporation of the Notice of Conversion (the “Delivery Date”).
In the event the Common Stock is electronically transferable, then delivery of the Common Stock must be made by electronic transfer provided request for such electronic transfer has been made by the Holder. A Series K Preferred Stock
certificate representing the balance of the Series K Preferred Stock not so converted will be provided by the Corporation to the Holder if requested by Holder, provided the Holder has delivered the original Series K Preferred Stock certificate to
the Corporation. To the extent that a Holder elects not to surrender Series K Preferred Stock for reissuance upon partial payment or conversion, the Holder hereby indemnifies the Corporation against any and all loss or damage attributable to a
third-party claim in an amount in excess of the actual amount of the Stated Value of the Series K Preferred Stock then owned by the Holder. 
 In the case of the exercise of the conversion rights set forth in Section 4(a), the conversion privilege shall be deemed to have been exercised and the shares of Common Stock issuable upon such conversion shall be deemed to have been
issued upon the date of receipt by the Corporation of the Notice of Conversion. The person or entity entitled to receive Common Stock issuable upon such conversion shall, on the date such conversion privilege is deemed to have been exercised and
thereafter, be treated for all purposes as the record holder of such Common Stock and shall on the same date cease to be treated for any purpose as the record holder of such shares of Series K Preferred Stock so converted. 
 Upon the conversion of any shares of Series K Preferred Stock, no adjustment or payment shall be made with respect to such converted shares on account
of any dividend on the Common Stock, except that the holder of such converted shares shall be entitled to be paid any dividends declared on shares of Common Stock after conversion thereof. 
 The Corporation shall not be required, in connection with any conversion of Series K Preferred Stock, and payment of dividends on Series K Preferred
Stock to issue a fraction of a share of its Series K Preferred Stock or Common Stock and shall instead deliver a stock certificate representing the nearest whole number. 
  

 3 

 (d) The Conversion Price determined pursuant to Section 4(b) shall be subject to adjustment from
time to time as follows: 
 (i) In case the Corporation shall at any time (A) declare any dividend or distribution on its Common Stock
or other securities of the Corporation other than the Series K Preferred Stock, (B) split or subdivide the outstanding Common Stock, (C) combine the outstanding Common Stock into a smaller number of shares, or (D) issue by
reclassification of its Common Stock any shares or other securities of the Corporation, then in each such event the Conversion Price shall be adjusted proportionately so that the Holders of Series K Preferred Stock shall be entitled to receive the
kind and number of shares or other securities of the Corporation which such Holders would have owned or have been entitled to receive after the happening of any of the events described above had such shares of Series K Preferred Stock been converted
immediately prior to the happening of such event (or any record date with respect thereto). Such adjustment shall be made whenever any of the events listed above shall occur. An adjustment made to the Conversion Price pursuant to this
Section 4(d)(i) shall become effective immediately after the effective date of the event. 
 (ii) For so long as Series K Preferred
Stock is outstanding, the Holder is granted the anti-dilution and price protection rights set forth in the Subscription Agreement and herein. 
 (e) (i) In case of any merger of the Corporation with or into any other corporation or entity (other than a merger in which the Corporation is the surviving or continuing corporation and which does not result in any reclassification,
conversion, or change of the outstanding shares of Common Stock) then unless the right to convert shares of Series K Preferred Stock shall have terminated as part of such merger, lawful provision shall be made so that Holders of Series K Preferred
Stock shall thereafter have the right to convert each share of Series K Preferred Stock into the kind and amount of shares of stock and/or other securities or property receivable upon such merger by a Holder of the number of shares of Common Stock
into which such shares of Series K Preferred Stock might have been converted immediately prior to such consolidation or merger. Such provision shall also provide for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in sub-paragraph (d) of this Section 4. The foregoing provisions of this Section 4(e) shall similarly apply to successive mergers. 
 (ii) In case of any sale or conveyance to another person or entity of the property of the Corporation as an entirety, or substantially as an entirety,
in connection with which shares or other securities or cash or other property shall be issuable, distributable, payable, or deliverable for outstanding shares of Common Stock, then, unless the right to convert such shares shall have terminated,
lawful provision shall be made so that the Holders of Series K Preferred Stock shall thereafter have the right to convert each share of the Series K Preferred Stock into the kind and amount of shares of stock or other securities or property that
shall be issuable, distributable, payable, or deliverable upon such sale or conveyance with respect to each share of Common Stock immediately prior to such conveyance. 
 (f) Whenever the number of shares to be issued upon conversion of the Series K Preferred Stock is required to be adjusted as provided in this Section 4, the Corporation shall forthwith compute the adjusted number
of shares to be so issued and prepare a certificate setting forth such adjusted conversion amount and the facts upon which such adjustment is based, and such certificate shall forthwith be filed with the Transfer Agent for the Series K Preferred
Stock and the Common Stock; and the Corporation shall mail to each Holder of record of Series K Preferred Stock notice of such adjusted conversion price. 
 (g) In case at any time the Corporation shall propose: 
  

 4 

 (i) to pay any dividend or distribution payable in shares upon its Common Stock or make any distribution
(other than cash dividends) to the holders of its Common Stock; or 
 (ii) to offer for subscription to the holders of its Common Stock any
additional shares of any class or any other rights; or 
 (iii) any capital reorganization or reclassification of its shares or the merger
of the Corporation with another corporation or entity (other than a merger in which the Corporation is the surviving or continuing corporation and which does not result in any reclassification, conversion, or change of the outstanding shares of
Common Stock); or 
 (iv) the voluntary dissolution, liquidation or winding-up of the Corporation; then, and in any one or more of said
cases, the Corporation shall cause at least fifteen (15) days prior notice of the date on which (A) the books of the Corporation shall close or a record be taken for such stock dividend, distribution, or subscription rights, or
(B) such capital reorganization, reclassification, merger, dissolution, liquidation or winding-up shall take place, as the case may be, to be mailed to the Transfer Agent for the Series K Preferred Stock and for the Common Stock and to the
Holders of record of the Series K Preferred Stock. 
 (h) So long as any shares of Series K Preferred Stock or any Obligation Amount shall
remain outstanding and the Holders thereof shall have the right to convert the same in accordance with provisions of this Section 4, the Corporation shall at all times reserve from the authorized and unissued shares of its Common Stock that
would be necessary to allow the conversion of the entire Obligation Amount. 
 (i) The term “Common Stock” as used in this
Certificate shall mean the $.01 par value Common Stock of the Corporation as such stock is constituted at the date of issuance thereof or as it may from time to time be changed, or shares of stock of any class or other securities and/or property
into which the shares of Series K Preferred Stock shall at any time become convertible pursuant to the provisions of this Section 4. 
 (j) The Corporation shall pay the amount of any and all issue taxes (but not income taxes) which may be imposed in respect of any issue or delivery of stock upon the conversion of any shares of Series K Preferred Stock, but all transfer
taxes and income taxes that may be payable in respect of any change of ownership of Series K Preferred Stock or any rights represented thereby or of stock receivable upon conversion thereof, shall be paid by the person or persons surrendering such
stock for conversion. 
 (k) In the event a Holder shall elect to convert any shares of Series K Preferred Stock as provided herein, the
Corporation may not refuse conversion based on any claim that such Holder or any one associated or affiliated with such Holder has been engaged in any violation of law, or for any other reason unless, an injunction from a court, on notice,
restraining and or enjoining conversion of all or part of said shares of Series K Preferred Stock shall have been issued and the Corporation posts a surety bond for the benefit of such Holder in the Obligation Amount sought to be converted, which is
subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable to such Holder in the event it obtains judgment. 
 (l) In addition to any other rights available to the Holder, if the Corporation fails to deliver to the Holder such certificate or certificates pursuant
to Section 4(c) by the Delivery Date and if within seven (7) business days after the Delivery Date the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by such Holder
of the Common Stock which the Holder anticipated receiving upon such conversion (a “Buy-In”), then the Corporation shall pay in cash 

  

 5 

 
to the Holder (in addition to any remedies available to or elected by the Holder) within five (5) business days after written notice from the Holder,
the amount by which (A) the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (B) the aggregate Stated Value of the shares of Series K Preferred Stock for which
such conversion was not timely honored, together with interest thereon at a rate of 15% per annum, accruing until such amount and any accrued interest thereon is paid in full (which amount shall be paid as liquidated damages and not as a
penalty). For example, if the Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of $10,000 of Stated Value of Series K Preferred Stock, the Corporation shall be
required to pay the Holder $1,000, plus interest. The Holder shall provide the Corporation written notice indicating the amounts payable to the Holder in respect of the Buy-In. 
 (m) Notwithstanding anything contained herein to the contrary, shares of Series K Preferred Stock shall not be convertible by a Holder, in whole or in
part, and the Corporation shall not give effect to any such conversion of Series K Preferred Stock, if, after giving effect to such conversion, the Holder, together with any affiliate of the Holder (including any person or company acting jointly or
in concert with the Holder) would in the aggregate beneficially own, or exercise control or direction over that number of voting securities of the Corporation which is 9.99% or greater of the total issued and outstanding voting securities of the
Corporation immediately after giving effect to such conversion; provided, however, that upon a Holder providing the Corporation with sixty-one (61) days notice (the “Waiver Notice”) that such Holder would like to waive
this Section 4(m) with regard to any or all shares of Common Stock issuable upon conversion of Series K Preferred Stock, this Section 4(m) will be of no force or effect with regard to all or a portion of the Series K Preferred Stock
referenced in the Waiver Notice. For purposes of this Section 4(m), beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended. 
 5. Voting Rights. The Holder of shares of Series K Preferred Stock shall not have voting rights except as described in Section 6 hereof.

 6. Amendments to Charter. The Corporation shall not amend its certificate of incorporation without the approval by the holders of
at least 70% of the then outstanding shares of Series K Preferred Stock if such amendment would: 
 (a) change the relative seniority rights
of the Holders of Series K Preferred Stock as to the payment of dividends in relation to the holders of any other capital stock of the Corporation, or create any other class or series of capital stock entitled to seniority as to the payment of
dividends in relation to the Holders of Series K Preferred Stock; 
 (b) reduce the amount payable to the Holders of Series K Preferred Stock
upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation, or change the relative seniority of the liquidation preferences of the Holders of Series K Preferred Stock to the rights upon liquidation of the holders of
other capital stock of the Corporation, or change the dividend rights of the Holders of Series K Preferred Stock; 
 (c) cancel or modify the
conversion rights of the Holders of Series K Preferred Stock provided for in Section 4 herein; or 
 (d) cancel or modify the rights of
the Holders of the Series K Preferred Stock provided for in this Section 6. 
  

 6 

 7. Redemption. 
 (a) At such time as the Corporation completes a subsequent financing, of either debt or equity, or a combination of debt or equity, in one or more tranches, resulting in the receipt of gross proceeds to the
Corporation of $6,000,000 or more (a “Subsequent Financing”), each Holder may require the Corporation to redeem, at the sole option of the Holder, all or a portion of each Holder’s Series K Preferred Stock outstanding at such time at
the Stated Value, including any accrued but unpaid dividend, rounded up to the quarter-end of the quarter of redemption, plus an amount equal to two additional quarters’ dividends. The Corporation shall provide notice to the Holders within 5
days of the completion of such subsequent financing offering, and the Holders shall have 10 days following the issuance of such notice in order to elect redemption. Payment of the redemption amount as aforesaid shall be made within 30 days of
receipt of such written election and against surrender of any stock certificates representing the shares of Series C Preferred Stock to be redeemed. 
 (b) The Corporation shall also have the right, at its sole option, (i) to require the Holders to convert their Series K Preferred Stock outstanding at such time, in their entirety, into Common Stock of the
Corporation at the conversion price hereinabove described, or (ii) to redeem the Series K Preferred Stock outstanding at such time, in their entirety, at the Stated Value, including any accrued but unpaid dividend, rounded up to the quarter-end
of the quarter of redemption, plus an amount equal to two additional quarters’ dividends, but in each such option, only in the event the Volume Weighted Average Price (“VWAP”) of the Common Stock of the Corporation trades at $0.25 per
share or higher for at least 15 consecutive trading days. In the case of (c)(ii) above, the Corporation shall provide written notice to the Holders of redemption within 10 days of such trading event, and the Holders shall have 10 days following
issuance of such notice to elect to convert their shares of Series K Preferred Stock into Common Stock of the Corporation or accept redemption, with payment by the Corporation to be made within 40 days of such written notice by the Corporation. The
Series K Preferred Stock shall be deemed automatically cancelled and no longer outstanding upon the Corporation’s payment of such redemption price in full. 
 (c) The Corporation shall also have the right, at its sole option, to redeem all or a portion of the Series K Preferred Stock, and any accrued and unpaid dividends, rounded up to the quarter-end of the quarter of
redemption, plus an amount equal to two additional quarters’ dividends, at any time after the third anniversary of initial issuance the Series K Preferred Stock. The Corporation shall provide written notice to the Holders of redemption at least
20 days’ prior to the date fixed for redemption, and the Holders shall have 10 days following issuance of such notice to elect to convert their shares of Series K Preferred Stock into Common Stock of the Corporation or accept redemption, with
payment by the Corporation to be made within 40 days of such written notice by the Corporation. The outstanding shares of Series C Preferred Stock shall be deemed automatically cancelled and no longer outstanding upon the Corporation’s payment
of such redemption price in full. 
  

 7 

 (d) The Corporation shall, to the extent permitted by applicable law, redeem the Series K Preferred
Stock, in their entirety, at the Stated Value, including any accrued but unpaid dividends, rounded up to the quarter-end of the quarter of redemption, upon the happening of any of the following events: (i) the Corporation shall be adjudicated
as bankrupt or makes an assignment for the benefit of creditors; or (ii) the Corporation shall apply for or consent to the appointment of a receiver, trustee, or similar officer for it or for all or any substantial part of its property; or such
receiver, trustee or similar officer shall be appointed without the application or consent of the Corporation and such appointment shall continue undischarged for a period of 60 days; or (iii) the Corporation shall institute any bankruptcy,
insolvency, reorganization, arrangement, readjustment of debt, dissolution, liquidation or similar proceeding relating to it under the laws of any jurisdiction; or (iv) any such proceeding shall be instituted against the Corporation and shall
remain undismissed for a period of 60 days; or (v) any judgment, writ, warrant of attachment or execution or similar process shall be issued or levied against a substantial part of the property of the Corporation and such judgment, writ, or
similar process shall not be released, vacated or fully bonded within 60 days after its issue or levy. The outstanding shares of Series K Preferred Stock shall be deemed automatically cancelled and no longer outstanding upon the Corporation’s
payment of such redemption price in full. 
 8. Restriction on Subsequent Financing. As long as the Series K Preferred Stock is
outstanding, the Corporation shall not consummate a financing of its Common Stock, in one or more tranches, at a price of less than $0.10 per share (or a debt financing, convertible into Common Stock at a conversion ratio of less than $0.10 per
share), for gross proceeds less than $6,000,000, without the prior written consent of the Holders, which consent will not be unreasonably withheld. 
 9. Status of Converted or Redeemed Stock. In case any shares of Series K Preferred Stock shall be redeemed or otherwise repurchased or reacquired, the shares so redeemed, converted, or reacquired shall resume the status of authorized
but unissued shares of Preferred Stock and shall no longer be designated as Series K Preferred Stock. 
 10. Authority to Amend. This
Certificate of Amendment was adopted by the Corporation’s Board of Directors on March 30, 2007, and no stockholder consent was required for the adoption thereof pursuant to the authority conferred upon the Board of Directors by the
Certificate of Incorporation of said Corporation. The Board of Directors shall be empowered to eliminate the Series K Preferred Stock at any time there are no shares of Series K Preferred Stock outstanding, and, except as otherwise provided herein,
the Board of Directors shall be empowered to modify the terms of and/or increase or decrease (but not below the number of then outstanding shares) the number of authorized shares of Series K Preferred Stock, all without stockholder approval.

distribution contemplated thereby (determined as herein provided), promptly provide to the holders of the Registrable Securities copies of all filings and Commission letters of comment and notify Subscribers (by telecopier or by email ) on or before
6:00 PM EST not later than the second business day after the Company receives notice that (i) the Commission has no comments or no further comments on the Registration Statement, and (ii) the registration statement has been declared
effective; 
  

 12 

 (b) prepare and file with the Commission such amendments and supplements to such registration statement
and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until such registration statement has been effective for a period of two (2) years, and comply with the provisions of the 1933 Act
with respect to the disposition of all of the Registrable Securities covered by such registration statement in accordance with the Sellers’ intended method of disposition set forth in such registration statement for such period; 
 (c) furnish to the Sellers, at the Company’s expense, such number of copies of the registration statement and the prospectus included therein
(including each preliminary prospectus) as such persons reasonably may request in order to facilitate the public sale or their disposition of the securities covered by such registration statement or make them electronically available; 
 (d) use its commercially reasonable best efforts to register or qualify the Registrable Securities covered by such registration statement under the
securities or “blue sky” laws of such jurisdictions as the Sellers shall reasonably request in writing, provided, however, that the Company shall not for any such purpose be required to qualify generally to transact business as a foreign
corporation in any jurisdiction where it is not so qualified or to consent to general service of process in any such jurisdiction; 
 (e) if
applicable, list the Registrable Securities covered by such registration statement with any securities exchange on which the Common Stock of the Company is then listed; and 
 (f) notify the Subscribers of the Company’s becoming aware that a prospectus relating thereto is required to be delivered under the 1933 Act, of the
happening of any event of which the Company has knowledge as a result of which the prospectus contained in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing or which becomes subject to a Commission, state or other governmental order suspending the effectiveness of the registration
statement covering any of the Shares. 
 12.3. Provision of Documents. In connection with each registration described in this
Section 12, each Seller will furnish to the Company in writing such information and representation letters with respect to itself and the proposed distribution by it as reasonably shall be necessary in order to assure compliance
with federal and applicable state securities laws. The Company’s obligation to register each Subscriber’s Registrable Securities is subject to 
 12.4. Non-Registration Events. The Company and the Subscribers agree that the Sellers will suffer damages if the Registration Statement is not filed by the Filing Date and not declared effective by the
Commission by the Effective Date, and maintained in the manner and within the time periods contemplated by Section 12 hereof, and it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if
(A) the Registration Statement is not filed on or before the Filing Date, (B) is not declared effective on or before the Effective Date, or (C) the Registration Statement is filed and declared effective but shall thereafter cease to
be effective without being succeeded within fifteen (15) business days by an effective replacement or amended registration statement or for a period of time which shall exceed 30 days in the aggregate per year (defined as a period of 365 days
commencing on the Actual Effective Date (each such event referred to in clauses (A) through (C) of this Section 12.4 is referred to herein as a “Non-Registration Event”), then the Company shall
deliver to the holder of Registrable Securities, as Liquidated Damages, an amount equal to one and one half percent (1.5%) for each thirty (30) days or part thereof of the Purchase Price of the Preferred Stock remaining unconverted and
purchase price of Shares issued upon conversion of the Obligation Amount (as defined in 

  

 13 

 
the Certificate of Designation) owned of record by such holder which are subject to such Non-Registration Event. The Company must pay the Liquidated Damages
in cash. The Liquidated Damages must be paid within ten (10) days after the end of each thirty (30) day period or shorter part thereof for which Liquidated Damages are payable. Notwithstanding the foregoing, the Company shall not be liable
to a Subscriber under this Section 12.4 for any events or delays occurring as a consequence of the acts or omissions of the Subscribers contrary to the obligations undertaken by Subscribers in this Agreement. Liquidated Damages
will not accrue nor be payable pursuant to this Section 12.4 nor will a Non-Registration Event be deemed to have occurred for times during which Registrable Securities are transferable by the holder of Registrable Securities
pursuant to Rule 144(k) under the 1933 Act. 
 12.5. Expenses. All expenses incurred by the Company in complying with Section 10,
including, without limitation, all registration and filing fees, printing expenses (if required), fees and disbursements of counsel and independent public accountants for the Company, fees and expenses (including reasonable counsel fees) incurred in
connection with complying with state securities or “blue sky” laws, fees of the National Association of Securities Dealers, Inc., transfer taxes, and fees of transfer agents and registrars, are called “Registration
Expenses.” All selling commissions applicable to the sale of Registrable Securities are called “Selling Expenses.” The Company will pay all Registration Expenses in connection with the registration statement
under Section 12. The Sellers shall be responsible for Selling Expenses attributable to the sale of their respective Securities. 
 12.6. Indemnification and Contribution. 
 (a) In the event of a registration of any Registrable Securities under the 1933 Act
pursuant to Section 12, the Company will, to the extent permitted by law, indemnify and hold harmless each Subscriber whose securities are included in the Registration Statement (each, a “Seller”), each
officer of the Seller, each director of the Seller, each underwriter of such Registrable Securities thereunder and each other person, if any, who controls such Seller or underwriter within the meaning of the 1933 Act, against any losses, claims,
damages or liabilities, joint or several, to which the Seller, or such underwriter or controlling person may become subject under the 1933 Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise
out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Registrable Securities was registered under the 1933 Act pursuant to
Section 12, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading in light of the circumstances when made, and will subject to the provisions of Section 12.6(c) reimburse the Seller, each such underwriter and each such
controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable to the Seller to
the extent that any such damages arise out of or are based upon an untrue statement or omission made in any preliminary prospectus if (i) the Seller failed to send or deliver a copy of the final prospectus delivered by the Company to the Seller
with or prior to the delivery of written confirmation of the sale by the Seller to the person asserting the claim from which such damages arise, (ii) the final prospectus would have corrected such untrue statement or alleged untrue statement or
such omission or alleged omission, or (iii) to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with
information furnished by any Seller, or any such controlling person in writing specifically for use in such registration statement or prospectus. 
  

 14 

 (b) In the event of a registration of any of the Registrable Securities under the 1933 Act pursuant to
Section 12, each Seller severally but not jointly will, to the extent permitted by law, indemnify and hold harmless the Company, and each person, if any, who controls the Company within the meaning of the 1933 Act, each officer of
the Company who signs the registration statement, each director of the Company, each underwriter and each person who controls any underwriter within the meaning of the 1933 Act, against all losses, damages or liabilities, joint or several, to which
the Company or such officer, director, underwriter or controlling person may become subject under the 1933 Act or otherwise, insofar as such losses, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in the registration statement under which such Registrable Securities were registered under the 1933 Act pursuant to Section 12, any preliminary prospectus or final prospectus contained
therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will
reimburse the Company and each such officer, director, underwriter and controlling person after a non-appealable judgment or determination for any legal or other expenses reasonably incurred by them in connection with investigating or defending any
such loss, damage, liability or action, provided, however, that the Seller will be liable hereunder in any such case if and only to the extent that any such loss, damage or liability arises out of or is based solely upon an untrue
statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such Seller, as such, furnished in writing to the Company by such Seller specifically for use in such
registration statement or prospectus, and provided, further, however, that the liability of the Seller hereunder shall be limited to the net proceeds actually received by the Seller from the sale of Registrable Securities covered by such
registration statement. 
 (c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any
liability which it may have to such indemnified party other than under this Section 12.6(c) and shall only relieve it from any liability which it may have to such indemnified party under this Section 12.6(c),
except and only if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to
such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 12.6(c) for any legal expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected, provided, however, that, if the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or if the interests of the
indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified parties, as a group, shall have the right to select one separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. 
 13. Prohibition Against Conversion Right. Notwithstanding anything to the contrary in Section 7(b) of the Certificate of Designation, the
Company agrees and acknowledges that it shall not require the Subscriber or any assignee, purchaser or other transferee of Preferred Stock to convert their Preferred Stock into Common Stock in accordance with Section 7(b)(i) of the Certificate
of Designation. Any notice of or action to effect conversion of such Preferred Stock pursuant to Section 7(b)(i) of the Certificate of Designation shall be null and void. 
  

 15

The Company may change
its address for notices but only to an address and fax number located in the United States. 
 (b) Entire Agreement; Assignment. This
Agreement and other documents delivered in connection herewith represent the entire agreement between the parties hereto with respect to the subject matter hereof and may be amended only by a writing executed by both parties. Neither the Company nor

 (d) Law Governing this Agreement. This Agreement shall be governed by and construed in
accordance with the laws of the State of Florida without regard to conflicts of laws principles that would result in the application of the substantive laws of another jurisdiction. Any action brought by either party against the other concerning the

inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid or unenforceable under any law shall not affect the validity or
enforceability of any other provision of any agreement. 
  

 16 

 (e) Specific Enforcement, Consent to Jurisdiction. The Company and Subscriber acknowledge and
agree that irreparable damage may occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to
seek one or more preliminary and final injunctions to prevent or cure breaches of the provisions of this Agreement and to enforce specifically the terms and provisions hereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity. Subject to Section 14(d) hereof, each of the Company, Subscriber and any signatory hereto in his personal capacity hereby waives, and agrees not to assert in any such suit, action or proceeding, any
claim that it is not personally subject to the jurisdiction in Florida of such court, that the suit, action or proceeding is brought in an inconvenient forum or that the venue of the suit, action or proceeding is improper. Nothing in this Section
shall affect or limit any right to serve process in any other manner permitted by law. 
 (f) Independent Nature of Subscribers. The
Company acknowledges that the obligations of each Subscriber under the Transaction Documents are several and not joint with the obligations of any other Subscriber, and no Subscriber shall be responsible in any way for the performance of the
obligations of any other Subscriber under the Transaction Documents. The Company acknowledges that each Subscriber has represented that the decision of each Subscriber to purchase Securities has been made by such Subscriber independently of any
other Subscriber and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company
which may have been made or given by any other Subscriber or by any agent or employee of any other Subscriber, and no Subscriber or any of its agents or employees shall have any liability to any Subscriber (or any other person) relating to or
arising from any such information, materials, statements or opinions. The Company acknowledges that nothing contained in any Transaction Document, and no action taken by any Subscriber pursuant hereto or thereto (including, but not limited to,
the (i) inclusion of a Subscriber in the Registration Statement and (ii) review by, and consent to, such Registration Statement by a Subscriber) shall be deemed to constitute the Subscribers as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Subscribers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Company
acknowledges that each Subscriber shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of the Transaction Documents, and it shall not be necessary for any other Subscriber
to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that it has elected to provide all Subscribers with the same terms and Transaction Documents for the convenience of the Company and not because
Company was required or requested to do so by the Subscribers. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption that the Subscribers are in any way acting in concert or as a
group with respect to the Transaction Documents or the transactions contemplated thereby. 
 (g) As used in the Agreement, “consent
of the Subscribers” or similar language means the consent of holders of not less than 70% of the total of the Shares issued and issuable upon conversion of outstanding Preferred Stock owned by Subscribers on the date consent is requested.

 (h) No consideration shall be offered or paid to any person to amend or consent to a waiver or modification of any provision of the
Transaction Documents unless the same consideration is also offered to all the parties to the Transaction Documents.
