(3)CONVERSION OF DEBENTURE.    This Debenture shall be convertible into shares of the Company’s Common Stock, on the terms and conditions set forth in this Section 3.

(a)Conversion Right. Subject to the provisions of this Section 3(c), upon and after an Event of Default, the Holder shall be entitled to convert any portion of the outstanding and

unpaid Conversion Amount into fully paid and nonassessable shares of Common Stock, at the Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to this Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up or down to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount.

(i)“Conversion Amount” means the portion of the Principal and accrued Interest to be converted or otherwise with respect to which this determination is being made.

(ii)“Conversion Price” means, as of any Conversion Date or other date of determination the lower of (i) $1.12 per share (the “Fixed Price”) or (ii) 90% of the lowest daily VWAP during the ten (10) consecutive Trading Days immediately preceding the Conversion Date (the “Variable Price”) or other date of determination (the “Variable Measurement Period”), which solely in the case of the Variable Price shall not be lower than the Floor Price. The Conversion Price shall be adjusted from time to time pursuant to the other terms and conditions of this Debenture.

(b)Mechanics of Conversion.

(i)Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”), the Holder shall (A) transmit by email or facsimile with confirmation of delivery (or otherwise deliver by method set forth in Section 7), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit A (the “Conversion Notice”) to the Company and (B) if required by Section 3(b)(iii), surrender this Debenture to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Debenture in the case of its loss, theft or destruction). On or before the third (3rd) Business Day following the date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (X) provided that the Transfer Agent is participating in the Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program, (I) if legends are not required to be placed on certificates of Common Stock credit such aggregate number of shares of Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system, or (II) if legends are required to be placed on certificates of Common Stock, credit such aggregate number of shares of Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account on the Company’s stock ledger as maintained by the Transfer Agent or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled which certificates shall not bear any restrictive legends unless required pursuant to rules and regulations of the Commission. If this Debenture is physically surrendered for conversion and the outstanding Principal of this Debenture is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Debenture and at its own expense, issue and deliver to the Holder a new Debenture representing the outstanding Principal not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Debenture shall be treated for all purposes as the record holder or holders of such shares of Common Stock upon the transmission of a Conversion Notice.

(ii)Company’s Failure to Timely Convert. If within three (3) Trading Days after the Company’s receipt of a copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC or the Transfer Agent, as applicable, for the number of shares of Common Stock to which the Holder is entitled upon such holder’s conversion of any Conversion Amount (a “Conversion Failure”), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated

receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid Price on the Conversion Date.

(iii)Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Debenture in accordance with the terms hereof, the Holder shall not be required to physically surrender this Debenture to the Company unless (A) the full Conversion Amount represented by this Debenture is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Debenture upon physical surrender of this Debenture. The Holder and the Company shall maintain records showing the Principal and Interest converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Debenture upon conversion.

(c)Limitations on Conversions.

(i)Beneficial Ownership. The Holder shall not have the right to convert any portion of this Debenture or receive shares of Common Stock as payment of Interest hereunder to the extent that after giving effect to such conversion or receipt of such Interest payment, the Holder, together with any affiliate thereof, would beneficially own (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to such conversion or receipt of shares as payment of interest. Since the Holder will not be obligated to report to the Company the number of shares of Common Stock it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of 4.99% of the then outstanding shares of Common Stock without regard to any other shares which may be beneficially owned by the Holder or an affiliate thereof, the Holder shall have the authority, responsibility and obligation to determine whether the restriction contained in this Section will limit any particular conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the Principal amount of this Debenture is convertible shall be the responsibility and obligation of the Holder. The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than 65 days prior notice to the Company. Other Holders shall be unaffected by any such waiver.

(d)Other Provisions.

(i)The Company shall at all times reserve and keep available out of its authorized Common Stock the full number of shares of Common Stock issuable upon conversion of all outstanding amounts under this Debenture; and within three (3) Business Days following the receipt by the Company of a Holder’s notice that such minimum number of Underlying Shares is not so reserved, the Company shall promptly reserve a sufficient number of shares of Common Stock to comply with such requirement.

(ii)All calculations under this Section 3 shall be rounded to the nearest $0.0001 or whole share.

(iii)The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock solely for the purpose of issuance upon conversion of this Debenture and payment of Interest on this Debenture, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder, not less than such number of shares of the Common Stock as shall be issuable (taking into account the adjustments and restrictions set forth herein) upon the conversion of the outstanding Principal of this Debenture and payment of Interest hereunder. The Company covenants that all shares of Common

Stock that shall be so issuable shall, upon issue, be duly and validly authorized, issued and fully paid, nonassessable.

(iv)Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 2 herein for the Company’s failure to deliver certificates representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief, in each case without the need to post a bond or provide other security. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(v)Legal Opinions. The Company is obligated to cause its legal counsel to deliver legal opinions to the Company’s Transfer Agent in connection with any legend removal upon the expiration of any holding period or other requirement for which the Underlying Shares may bear legends restricting the transfer thereof. To the extent that are not provided (either timely or at all), then, in addition to being an Event of Default hereunder, the Company agrees to reimburse the Holder for all reasonable costs incurred by the Holder in connection with any legal opinions paid for by the Holder in connection with sale or transfer of Underlying Shares of Common Stock. The Holder shall notify the Company of any such costs and expenses it incurs that are referred to in this section from time to time and all amounts owed hereunder shall be paid by the Company with reasonable promptness.

(e)Adjustments to Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, (i) any Fixed Price in effect immediately prior to such subdivision will be proportionately decreased and the number of shares of Common Stock issuable upon conversion of this Debenture will be proportionately increased and (ii) to the extent any day within a an applicable Variable Measurement Period are on or prior to the ex-date of applicable Adjustment Effective Time, the daily WVAP for such day will be proportionately reduced such that the number of shares of Common Stock obtainable upon conversion of this Debenture if the VWAP on such day was lowest during the Variable Measurement Period will be proportionately increased. If the Company at any time after the Issuance Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, (i) any Conversion Price in effect immediately prior to such combination will be proportionately increased and the number of shares of Common Stock issuable upon conversion of this Debenture will be proportionately decreased and (ii) to the extent any day within a an applicable Variable Measurement Period are on or prior to the ex-date of the applicable Adjustment Effective Time, the daily WVAP for such day will be proportionately increased such that the number of shares of Common Stock obtainable upon conversion of this Debenture if the VWAP on such day was lowest during the Variable Measurement Period will be proportionately reduced, provided however, no such adjustment set out in part (i) or (ii) of this sentence shall be made in respect of any combination, reverse stock split or other combination effected without the prior express written consent of the Holder. Any adjustment under this Section 3(e) shall become effective at the close of business on the date the subdivision or combination becomes effective (the “Adjustment Effective Time”).

(f)Notification of Adjustment. Whenever the Conversion Price is adjusted pursuant to Section 3 hereof, the Company shall promptly send the Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(g)The Company hereby expressly acknowledges and agrees that (i) the SDPA and all Transaction Documents to which it is a party are ratified and confirmed and shall remain in full force and effect, (ii) it has no set off, counterclaim, defense or other claim or dispute with respect to any Transaction Document, (iii) notwithstanding anything to the contrary in any Transaction Document, the term “Obligations” as used and defined in the Guaranty and any Security Document executed by the Company shall include all obligations under this Agreement and the other Transaction Documents and (iv) all obligations under this Agreement are duly secured by the Security Documents.

(h)The Company hereby covenants and agrees that, upon the request of the Holder, the Company shall take all necessary action, at the Issuer's expense, to ensure the prompt registration of the securities associated with this Secured Convertible Debenture, in accordance with applicable securities laws and regulations.

(4)INDEMNIFICATION.

With respect to the Company’s obligations under this Debenture and the other Transaction Documents:

To the fullest extent permitted by law, the Company shall, and hereby does, indemnify, hold harmless and defend the Holder, its investment manager and their respective directors, officers, partners, employees, agents, representatives, and successors and assigns of, and each Person, if any, who controls Holder within the meaning of the Securities Act or the Exchange Act (each, an “Indemnified Person”), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or several (collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body or the Commission, whether pending or threatened, whether or not an Indemnified Person is or may be a party thereto (“Indemnified Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in any filing made in any public filing (including, without limitation, any Periodic Reports) made by the Company with the Commission, or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation, any state securities law (the matters in the foregoing clauses (i) through (iii) being, collectively, “Violations”). The Company shall reimburse the Indemnified Persons and each such controlling person promptly as such expenses are incurred and are due and payable, for any legal fees or disbursements or other reasonable expenses incurred by them in connection with investigating or defending any such Claim.

Promptly after receipt by an Indemnified Person under this Section 4 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 4, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person; provided, however, that an Indemnified Person shall have the right to retain its own counsel with the fees and expenses of not more than one (1) counsel for such Indemnified Person to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person and any other party represented by such counsel in such proceeding. The Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its prior written consent; provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the prior written consent of the Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to

the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person under this Section 4, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

The indemnification required by this Section 4 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred.

The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

(5)CONTRIBUTION. To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 4 to the fullest extent permitted by law.

(6)REISSUANCE OF THIS DEBENTURE.

(a)Transfer. If this Debenture is to be transferred, the Holder shall surrender this Debenture to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Debenture (in accordance with Section 6(d)), registered in the name of the registered transferee or assignee, representing the outstanding Principal being transferred by the Holder (along with any accrued and unpaid interest thereof) and, if less than the entire outstanding Principal is being transferred, a new Debenture (in accordance with Section 6(d)) to the Holder representing the outstanding Principal not being transferred. The Holder and any assignee, by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of Section 3(c)(iii) following conversion of any portion of this Debenture, the outstanding Principal represented by this Debenture may be less than the Principal stated on the Principal Amount of this Debenture.

(c)Debenture Exchangeable for Different Denominations. This Debenture is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Debenture or Debentures (in accordance with Section 6(d)) representing in the aggregate the outstanding Principal of this Debenture, and each such new Debenture will represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender.

Whenever the Company is required to issue a new Debenture pursuant to the terms of this Debenture, such new Debenture (i) shall be of like tenor with this Debenture, (ii) shall represent, as indicated on the Principal Amount of such new Debenture, the Principal remaining outstanding (or in the case of a new Debenture being issued pursuant to Section 6(a) or Section 6(c), the Principal designated by the Holder which, when added to the principal represented by the other new Debentures issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Debenture immediately prior to such issuance of new Debentures), (iii) shall have an issuance date, as indicated on the Principal Amount of such new Debenture, which is the same as the Issuance Date of this Debenture, (iv) shall have the same rights and conditions as this Debenture, and (v) shall represent accrued and unpaid Interest from the Issuance Date.

Written confirmation of receipt (i) given by the recipient of such notice, consent, waiver or other communication, (ii) electronically generated upon sending the e-mail or (iii) provided by a nationally recognized overnight delivery service, shall be rebuttable evidence of personal service, receipt by e-mail or receipt from a nationally recognized overnight delivery service in accordance with clause (i), (ii) or (iii) above, respectively.

This Debenture is a direct obligation of the Company.

(9)This Debenture shall not entitle the Holder to any of the rights of a stockholder of the Company, including without limitation, the right to vote, to receive dividends and other distributions, or to receive any notice of, or to attend, meetings of stockholders or any other proceedings of the Company, unless and to the extent converted into shares of Common Stock in accordance with the terms hereof.

(10)After the Issuance Date, without the Holder’s consent, the Company will not and will not permit any of its Subsidiaries to, directly or indirectly, enter into, create, incur, assume or suffer to exist any indebtedness or any security interests or liens of any kind, on or with respect to any of its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom.

(11)Choice of Law; Venue.

(a)    Governing Law.

(14)Any waiver by the Holder of a breach of any provision of this Debenture shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Debenture.
