The Dividends set forth in clause (a) shall be paid upon the Mandatory Conversion Date, to the extent accrued as of the Mandatory Conversion Date and not previously paid as of such date. Notwithstanding the foregoing, to the extent that a Holder’s right to participate in any dividend of PIK Shares or any stock dividend declared on the Common Stock to which such Holder is entitled to pursuant to clause (b) of this Section 3 (“Dividend Shares”) would result in such Holder exceeding the Beneficial Ownership Limitation or the Control Limitation, then such Holder shall not be entitled to participate in any such dividend to such extent (or in the beneficial ownership of any PIK Shares or Dividend Shares as a result of such dividend to such extent) and the portion of such PIK Shares and/or Dividend Shares that would cause such Holder to exceed the Beneficial Ownership Limitation or the Control Limitation shall be held in abeyance by the Company for the benefit of such Holder (which shall not give the Holder any power to vote or dispose of such Dividend Shares) until such time, if ever, as such Holder’s beneficial ownership thereof would not result in such Holder exceeding the Beneficial Ownership Limitation or the Control Limitation. For the avoidance of doubt, at any time during which there is no effective registration statement for the issuance or resale of the PIK Shares or Dividend Shares, the Company may pay such dividends with unregistered Common Stock.

Section 4. Voting Rights. On any matter presented to the stockholders of the Company for their action or consideration at any meeting of stockholders of the Company (or by written consent of stockholders in lieu of meeting), and subject to the Beneficial Ownership Limitation set forth in Section 6(e) and the Control Limitation set forth in Section 6(f), each Holder of outstanding shares of Series C-3 Preferred Stock shall be entitled to cast the number of votes equal to the number of whole shares of Common Stock into which the shares of Series C-3 Preferred Stock held by such holder are convertible, subject to the Beneficial Ownership Limitation set forth in Section 6(e) and the Control Limitation set forth in Section 6(f), as of the record date for determining stockholders entitled to vote on such matter. Except as provided by law or by the other provisions of the Certificate of Incorporation, Holders of Series C-3 Preferred Stock shall vote together with the holders of Common Stock as a single class. The Holders shall be entitled to the same notice of any regular or special meeting of the stockholders as may or shall be given to holders of Common Stock entitled to vote at such meetings. As long as any shares of Series C-3 Preferred Stock are outstanding, the Company may not, without the affirmative vote of the Holders of the majority of the then outstanding shares of the Series C-3 Preferred Stock voting as a separate class, (a) alter or change adversely the powers, preferences or rights given to the Series C-3 Preferred Stock or alter or amend this Certificate of Designation, (b) alter or change adversely the powers, preferences or rights given to the Series C-1 Preferred Stock or alter or amend the Certificate of Designation of the Series C-1 Preferred Stock to provide for greater rights than the Series C-3 Preferred Stock, (c) alter or change adversely the powers, preferences or rights given to the Series C-2 Preferred Stock or alter or amend the Certificate of Designation of the Series C-2 Preferred Stock to provide for greater rights than the Series C-3 Preferred Stock, (d) authorize or create any class of stock ranking as to dividends, redemption or distribution of assets upon a liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, that is senior to the Series C-3 Preferred Stock, (e) amend its certificate of incorporation or other charter documents in any manner that adversely affects any rights of the Holders, (f) increase the number of authorized shares of Series C-3 Preferred Stock, or (g) enter into any agreement with respect to any of the foregoing. Notwithstanding anything contained herein to the contrary, no holder of Series C-3 Preferred Stock shall be entitled to vote on any matter presented to the Company’s stockholders relating to approving the conversion of such holder’s Series C-3 Preferred Stock into an amount in excess of the Control Limitation.

Section 5. Liquidation.

(a) The Series C-3 Preferred Stock shall, with respect to distributions of assets and rights upon the occurrence of any liquidation, dissolution or winding-up of the Company (“Liquidation”), rank: (i) junior to the Senior Securities, (ii) pari passu with the Parity Securities; and (iii) senior to the Junior Securities of the Company. Upon any Liquidation, after the satisfaction in full of the debts of the Company and payment of the liquidation preference to the Senior Securities, the Holders of shares of Series C-3 Preferred Stock shall be entitled to be paid, on a pari passu basis with the payment of any liquidation preference afforded to holders of any Parity Securities, for each share of Series C-3 Preferred Stock held thereby, out of (but only to the extent) the assets of the Company are legally available for distribution to its stockholders, an amount equal to the Stated Value per share (as adjusted for stock splits, stock dividends, combinations or other recapitalizations of the Series C-3 Preferred Stock), plus any accrued but unpaid dividends before any distribution or payment may be made to the holders of any Junior Securities. If the assets of the Company available for distribution to Holders of shares of Series C-3 Preferred Stock shall be insufficient to permit payment in full to such Holders of the sums which such Holders are entitled to receive in such case and of any liquidation preference afforded to holders of any Parity Securities, then all of the assets available for distribution to holders of the Series C-3 Preferred Stock and the Parity Securities shall be distributed among and paid to such holders ratably in proportion to the amounts that would be payable to such holders if such assets were sufficient to permit payment in full.

(b) After the Holders of all shares of Series C-3 Preferred Stock shall have been paid in full the amounts to which they are entitled pursuant to paragraph 5(a), the shares of Series C-3 Preferred Stock shall not be entitled to any further participation in any distribution of assets of the Company.

Section 6 Conversion.

(a) Conversions at Option of Holder. Each share of Series C-3 Preferred Stock (or fraction thereof) shall be convertible, at any time and from time to time, from and after the Original Issue Date at the option of the Holder thereof into that number of shares of Common Stock (subject to the Beneficial Ownership Limitation set forth in Section 6(e) and the Control Limitation set forth in Section 6(f)) determined by dividing the Stated Value by the Conversion Price then in effect. Holders shall effect conversions by providing the Company and the Transfer Agent, with the form of conversion notice attached hereto as Annex A (a “Notice of Conversion”). Each Notice of Conversion shall specify the number of shares of Series C-3 Preferred Stock to be converted, the number of shares of Series C-3 Preferred Stock owned prior to such conversion, the number of shares of Series C-3 Preferred Stock owned subsequent to such conversion and the date on which such conversion is to be effected, which date may not be prior to the date the applicable Holder delivers such Notice of Conversion to the Company pursuant to Section 6 and in accordance with Section 9 (such date, the “Optional Conversion Date”). Such Holder shall be deemed for all corporate purposes to have become the holder of record of the Conversion Shares with respect to which the shares of Series C-3 Preferred Stock have been converted as of the Optional Conversion Date. If no Optional Conversion Date is specified in a Notice of Conversion, the Optional Conversion Date shall be the date that such Notice of Conversion and Cancellation Request are deemed delivered to the Company in accordance with Section 9. The calculations and entries set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be required. To effect conversions of shares of Series C-3 Preferred Stock, a Holder shall not be required to surrender any Certificated Series C-3 Preferred Stock to the Company unless all of the shares of Series C-3 Preferred Stock represented by any such certificate are so converted, in which case such Holder shall deliver the Certificated Series C-3 Preferred Stock promptly following the Optional Conversion Date. To the extent that the Beneficial Ownership Limitation contained in Section 6(e) or the Control Limitation contained in Section 6(f) applies to the converting Holder, the determination of whether the Series C-3 Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Series C-3 Preferred Stock are convertible shall be in the sole discretion of such Holder, and the submission of a Notice of Conversion shall be deemed to be such Holder’s determination of whether the shares of Series C-3 Preferred Stock may be converted (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and how many shares of the Series C-3 Preferred Stock are convertible, in each case subject to the Beneficial Ownership Limitation or the Control Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this Section and the Company shall have no obligation to verify or confirm the accuracy of such determination.

(b) Mandatory Conversion. On the earliest to occur of: (i) the effective date of such conversion set forth in the Company Conversion Notice, provided that the Company may not deliver the Company Conversion Notice unless Holders of at least 50.1% of all outstanding shares of Series C Preferred Stock consented to such conversion prior to the delivery of the Company Conversion Notice; or (ii) the Fourth Anniversary (the earlier to occur of the foregoing, the “Mandatory Conversion Date” and together with an Optional Conversion Date, the “Conversion Date”), each outstanding share of Series C-3 Preferred Stock will automatically convert (subject to the Beneficial Ownership Limitation set forth in Section 6(e) and the Control Limitation contained in Section 6(f)) into such number of fully paid and non-assessable shares of Common Stock as is determined by dividing the Stated Value by the Conversion Price in effect on the Mandatory Conversion Date (a “Mandatory Conversion”). Within two Trading Days of (x) the Mandatory Conversion Date, if the shares of Series C-3 Preferred Stock are held in book entry form, or (y) such Holder’s surrender of Certificated Series C-3 Preferred Stock (or, if such registered holder alleges that such certificate has been lost, stolen or destroyed, a lost certificate affidavit and an indemnity or security reasonably acceptable to the Company (which shall not include the posting of any bond) to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate), the Company shall deliver: (I) to each Holder, the Conversion Shares issuable upon conversion of such Holder’s Series C-3 Preferred Stock via the Certificated Preferred Stock, and (II) the PIK Shares issuable upon Mandatory Conversion under Section 3, to Holders as of the Mandatory Conversion Date; provided that, any failure by the Holder to return Certificated Series C-3 Preferred Stock, if any, will have no effect on the Mandatory Conversion pursuant to this Section 6(b), which Mandatory Conversion will be deemed to occur on the Mandatory Conversion Date. To the extent that the Beneficial Ownership Limitation contained in Section 6(e) or the Control Limitation contained in Section 6(f) applies to any Holder, such Holder shall within five Business Days of such Holder’s receipt of the Company Conversion Notice, provide the Company with a written determination (a “Mandatory Conversion Determination”), delivered in accordance with Section 9, of whether such Holder’s Series C-3 Preferred Stock is convertible (in relation to other securities owned by such Holder together with any Affiliates and Attribution Parties) and of how many shares of Series C-3 Preferred Stock are convertible, and the submission of a Mandatory Conversion Determination shall be deemed to be such Holder’s determination of the maximum number of shares of Series C-3 Preferred Stock that may be converted, subject to the Beneficial Ownership Limitation or the Control Limitation and the portion of the shares of Common Stock issuable upon such Mandatory Conversion hereunder that would cause such Holder to exceed the Beneficial Ownership Limitation or the Control Limitation shall be held in abeyance by the Company for the benefit of such Holder (which shall not give the Holder any power to vote or dispose of such shares during such abeyance period) until such time, if ever, as such Holder’s beneficial ownership thereof would not result in such Holder exceeding the Beneficial Ownership Limitation or the Control Limitation. To ensure compliance with this restriction, each Holder will be deemed to represent to the Company each time it delivers a Mandatory Conversion Determination that such determination has not violated the restrictions set forth in Section 6(e) or Section 6(f) and the Company shall have no obligation to verify or confirm the accuracy of such determination.

(c) Conversion Shares. The aggregate number of Conversion Shares which the Company shall issue upon conversion of the Series C-3 Preferred Stock (whether pursuant to Section 6(a) or 6(b)) will be equal to the number of shares of Series C-3 Preferred Stock to be converted, multiplied by the Stated Value, divided by the Conversion Price in effect at the time of the conversion. For the avoidance of doubt, at any time during which there is no effective registration statement for the issuance or resale of the Conversion Shares, the Company may settle a conversion of the Series C-3 Preferred Stock (whether pursuant to Section 6(a) or 6(b)) with unregistered Common Stock.

(d) Mechanics of Conversion.

(i) Delivery of Conversion Shares upon Conversion. Promptly after the applicable Conversion Date, but in any case within the earlier of (i) two (2) Trading Days and (ii) the Standard Settlement Period (as defined below) thereof (the “Share Delivery Date”), the Company shall deliver, or cause to be delivered, to the converting Holder the number of Conversion Shares being acquired upon the conversion of the Series C-3 Preferred Stock pursuant to Section 6(a) or 6(b), as applicable, any PIK Shares to which the Holder is entitled pursuant to Section 3 that have not been previously issued, if any, and a wire transfer of immediately available funds in the amount of accrued and unpaid cash dividends, if any. Conversion Shares issuable hereunder shall be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with DTC through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and otherwise by physical delivery of a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the number of Conversion Shares and PIK Shares, if any, to which the Holder is entitled pursuant to such conversion to the address specified by the Holder in the Notice of Conversion or the Company Conversion Notice, as the case may be. The Company shall (A) deliver (or cause to be delivered) to the converting Holder who has converted less than all of such Holder’s Certificated Series C-3 Preferred Stock (1) a certificate or certificates, of like tenor, for the number of shares of Series C-3 Preferred Stock evidenced by any surrendered certificate or certificates less the number of shares of Series C-3 Preferred Stock converted. The Company agrees to maintain a transfer agent that is a participant in the DTC’s FAST program so long as any shares of Series C-3 Preferred Stock remain outstanding. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of Conversion.

(ii) Failure to Deliver Conversion Shares upon an Optional Conversion. If, in the case of any Notice of Conversion, such Conversion Shares are not delivered to or as directed by the applicable Holder by the Share Delivery Date, in addition to any other rights herein, the Holder shall be entitled to elect by written notice to the Transfer Agent, on behalf of the Company, at any time on or before its receipt of such Conversion Shares, to rescind such Conversion, in which event the Company shall promptly return to the Holder any Certificated Series C-3 Preferred Stock delivered to the Company and the Holder shall promptly return to the Company the Conversion Shares issued to such Holder pursuant to the rescinded Notice of Conversion.

(iii) Obligation Absolute; Partial Liquidated Damages. The Company’s obligation to issue and deliver the Conversion Shares upon conversion of Series C-3 Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by such Holder or any other person, and irrespective of any other circumstance which might otherwise limit such obligation of the Company to such Holder in connection with the issuance of such Conversion Shares; provided, however, that such delivery shall not operate as a waiver by the Company of any such action that the Company may have against such Holder. In the event a Holder shall elect to convert any or all of its Series C-3 Preferred Stock, the Company 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, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining conversion of all or part of the Series C-3 Preferred Stock of such Holder shall have been sought and obtained, and the Company posts a surety bond for the benefit of such Holder in the amount of 150% of the Stated Value of Series C-3 Preferred Stock which is subject to the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the Company shall issue Conversion Shares upon a properly noticed conversion. If the Company fails to deliver to a Holder such Conversion Shares pursuant to Section 6(d)(i) on the Share Delivery Date applicable to such conversion, the Company shall pay to such Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Stated Value of the Series C-3 Preferred Stock being converted, $10 per Trading Day (increasing to $20 per Trading Day on the fifth Trading Day after such damages begin to accrue) for each Trading Day after the Share Delivery Date until such Conversion Shares are delivered or Holder rescinds such conversion. Nothing herein shall limit a Holder’s right to pursue actual damages for the Company’s failure to deliver Conversion Shares within the period specified herein and such Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit a Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(iv) Compensation for Buy-In on Failure to Timely Deliver Conversion Shares Upon Conversion. In addition to any other rights available to the Holder, if the Company fails for any reason to deliver to a Holder the applicable Conversion Shares by the Share Delivery Date pursuant to Section 6(d)(i), and if after such Share Delivery Date such Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a “Buy-In”), then the Company shall (A) pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount, if any, by which (x) such Holder’s total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate number of Conversion Shares that such Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) (I) in the case of an Optional Conversion either (a) reissue (if surrendered) the shares of Series C-3 Preferred Stock equal to the number of shares of Series C-3 Preferred Stock submitted for conversion (in which case, such conversion shall be deemed rescinded) or (b) deliver to such Holder the number of shares of Common Stock that would have been issued if the Company had timely complied with its delivery requirements under Section 6(d)(i) and (II) in the case of a Mandatory Conversion, deliver to such Holder the number of shares of Common Stock that would have been issued if the Company had timely complied with its delivery requirements under Section 6(d)(i). For example, if a 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 shares of Series C-3 Preferred Stock with respect to which the actual sale price of the Conversion Shares (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Company shall be required to pay such Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to such Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver the Conversion Shares upon conversion of the shares of Series C-3 Preferred Stock as required pursuant to the terms hereof.

(v) Reservation of Shares Issuable Upon Conversion. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holders of the Series C-3 Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable (i) upon the conversion of all outstanding shares of Series C-3 Preferred Stock (taking into account the adjustments and restrictions of Section 7) and (ii) in respect of the PIK Shares. The Company covenants that all Conversion Shares and PIK Shares shall, when issued, be duly authorized, validly issued, fully paid and nonassessable.

(vi) Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of or as dividends on the Series C-3 Preferred Stock. As to any fraction of a share which a Holder would otherwise be entitled to upon such conversion or in respect of any such dividend, the Company shall round up to the next whole share of Common Stock.

(vii) Transfer Taxes and Expenses. The issuance of Conversion Shares on conversion of this Series C-3 Preferred Stock shall be made without charge to any Holder for any Transfer Agent fees, documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such Conversion Shares, provided that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such Conversion Shares upon conversion in a name other than that of the Holders of such shares of Series C-3 Preferred Stock and the Company shall not be required to issue or deliver such Conversion Shares and shall not be responsible for partial liquidated damages under Section 6(d)(iii) or penalties under Section 6(d)(iv) unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid.

(e) Beneficial Ownership Limitation. The Company shall not effect any conversion of the Series C-3 Preferred Stock, including, without limitation, a Mandatory Conversion, and a Holder shall not have the right to receive Dividend Shares hereunder or convert any portion of the Series C-3 Preferred Stock, to the extent that, after giving effect to the receipt of dividends hereunder or conversion set forth on the applicable Notice of Conversion, such Holder (together with such Holder’s Affiliates, and any Persons acting as a group together with such Holder or any of such Holder’s Affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock received as Dividend Shares or issuable upon conversion of the Series C-3 Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Series C-3 Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Series C-3 Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 6(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith (other than as it relates to a Holder relying on the number of shares issued and outstanding as provided by the Company pursuant to this Section). In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this Section 6(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company or (iii) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request (which may be via email) of a Holder, the Company shall within one Trading Day confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. The “Beneficial Ownership Limitation” shall be 4.99% (or, at the written election of any Holder delivered to the Company pursuant to the terms of Section 9 prior to the issuance of any shares of Series C-3 Preferred Stock, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of Series C-3 Preferred Stock held by the applicable Holder and/or the issuance of the Dividend Shares. A Holder, upon at least sixty-one (61) days advance written notice to the Company, may terminate, increase or decrease the Beneficial Ownership Limitation provisions of this Section 6(e); provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Series C-3 Preferred Stock held by the Holder and/or the issuance of the Dividend Shares, and the provisions of this Section 6(e) shall continue to apply. The limitations contained in this Section 6(e) shall apply to a successor holder of Series C-3 Preferred Stock. The limitations contained in this Section 6(e) and Section 7(b) shall terminate immediately at any time at which the Common Stock ceases to be an “equity security” as defined in Rule 13d-1(i) promulgated under the Exchange Act (or any successor rule).

(f) Control Limitation. Unless the Company obtains the approval of its stockholders for issuances of Common Stock in excess of such amount, the Company shall not effect any conversion of the Series C-3 Preferred Stock, including, without limitation, a Mandatory Conversion, and a Holder shall not have the right to receive dividends hereunder or convert any portion of the Series C-3 Preferred Stock, to the extent that, after giving effect to the receipt of dividends hereunder or conversion set forth on the applicable Notice of Conversion, the Holder, together with the Attribution Parties, would beneficially own in excess of the Control Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by such Holder and its Affiliates and Attribution Parties shall include the number of shares of Common Stock received as dividends or issuable upon conversion of the Series C-3 Preferred Stock with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted Series C-3 Preferred Stock beneficially owned by such Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, the Series C-3 Preferred Stock) beneficially owned by such Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 6(f), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith (other than as it relates to a Holder relying on the number of shares issued and outstanding as provided by the Company pursuant to this Section). For purposes of this Section 6(f), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company or (iii) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request (which may be via email) of a Holder, the Company shall within one Trading Day confirm orally and in writing to such Holder the number of shares of Common Stock then outstanding. The “Control Limitation” shall be 19.99% of the number of shares of the Common Stock outstanding immediately before giving effect to the issuance of shares of Common Stock issuable upon conversion of the Series C-3 Preferred Stock and/or the issuance of the Dividend Shares. The limitations contained in this paragraph shall apply to a successor holder of the Series C-3 Preferred Stock.

Section 7. Certain Adjustments.

(a) Stock Dividends and Stock Splits. If the Company, at any time while the Series C-3 Preferred Stock is outstanding: (A) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any other Common Stock Equivalents (which, for avoidance of doubt, will not include any shares of Common Stock issued by the Company upon conversion of this Series C-3 Preferred Stock or payment of a dividend on this Series C-3 Preferred Stock); (B) subdivides outstanding shares of Common Stock into a larger number of shares; (C) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares; or (D) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Company, then the Conversion Price will be multiplied by a fraction of which the numerator will be the number of shares of Common Stock (excluding any treasury shares of the Company) outstanding immediately before such event and of which the denominator will be the number of shares of Common Stock, or in the event that clause (D) of this Section 7(a) will apply shares of reclassified capital stock, outstanding immediately after such event. Any adjustment made pursuant to this Section 7(a) will become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and will become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b) Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 7(a) above, if at any time the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of such Holder’s Series C-3 Preferred Stock (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation or the Control Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance by the Company for the Holder (which shall not give the Holder any power to vote or dispose of such Purchase Rights) until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation or the Control Limitation).

(c) Pro Rata Distributions. During such time as this Series C-3 Preferred Stock is outstanding, if the Company declares or makes any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Series C-3 Preferred Stock, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Series C-3 Preferred Stock (without regard to any limitations on conversion hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation or the Control Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance by the Company for the benefit of the Holder (which shall not give the Holder any power to vote or dispose of such shares) until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation or the Control Limitation).

(d) Fundamental Transaction. If, at any time while the Series C-3 Preferred Stock is outstanding, (A) the Company effects any merger or consolidation of the Company with or into another Person, (B) the Company effects any sale of all or substantially all of its assets in one transaction or a series of related transactions, or (C) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (in any such case, a “Fundamental Transaction”), then, upon any subsequent conversion of the Series C-3 Preferred Stock, the Holders shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the “Alternate Consideration”). For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall adjust the Conversion Price in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holders shall be given the same choice as to the Alternate Consideration they receive upon any conversion of the Series C-3 Preferred Stock following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity in such Fundamental Transaction shall file a new Certificate of Designation with the same terms and conditions and issue to the Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders’ right to convert such preferred stock into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 7(d) and insuring that the Series C-3 Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

(e) Calculations. All calculations under this Section 7 will be made to the nearest cent or the nearest 1/100th of a share, as the case may be.

(f) Notice to the Holders.

Section 8. Miscellaneous.

(a) Notices. Any and all notices or other communications or deliveries to be provided to the Holders, the Company or the Transfer Agent hereunder, including, without limitation, any Notice of Conversion or Company Conversion Notice, shall be in writing and delivered personally, by facsimile, by e-mail, or sent by a nationally recognized overnight courier service (i) if to the Holders, at the Holder’s address set forth in the book and records of the Company or to another address of such Holder as may be specified by such Holder to the Company in a written notice delivered in accordance with this Section, or (ii) if to the Company, at 12707 High Bluff Dr., Suite 200, San Diego, CA 92130, email: spraill@delmarpharma.com or to another address as the Company may specify for such purposes by written notice to the Holders delivered in accordance with this Section.

(b) Absolute Obligation.

(c) Lost or Mutilated Series C-3 Preferred Stock Certificate. If a Holder alleges that such Holder’s Series C-3 Preferred Stock certificate has been lost, stolen or destroyed, the Company will only be obligated to issue a replacement certificate if the Holder delivers to the transfer agent, or the Company, as applicable: (i) a lost certificate affidavit; (ii) an indemnity bond in a form acceptable to the Company’s transfer agent, or if the Company acts as its own transfer agent, an agreement reasonably acceptable to the Company to indemnify the Company against any claim that may be made against the Company on account of the alleged loss, theft or destruction of such certificate; and (iii) any other documentation that the transfer agent or the Company, if the Company acts as its own transfer agent, may reasonably require.

All questions concerning the construction, validity, enforcement and interpretation of this Certificate of Designations shall be governed by and construed and enforced in accordance with the internal laws of the State of Nevada, without regard to the principles of conflict of laws thereof.
