Delivery shall be in book-entry or certificated form, or electronically through The Depository Trust Company or another established clearing corporation performing similar functions if available and permitted under applicable securities laws. Restrictive legends shall be retained or removed in accordance with applicable securities laws and the Transaction Agreement.

ii. Failure to Deliver Conversion Shares. 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, the Holder shall be entitled to elect by written notice to the Corporation at any time on or before its receipt of such Conversion Shares, to rescind such conversion, in which event the Corporation shall promptly return to the Holder any original Preferred Stock certificate delivered to the Corporation and the Holder shall promptly return to the Corporation the Conversion Shares issued to such Holder pursuant to the rescinded Notice of Conversion.

iii. Obligation to Deliver. Subject in all cases to Section 5(d), the Corporation shall issue and deliver the Conversion Shares upon conversion in accordance with this Certificate of Designation. No provision hereof shall require or permit issuance in violation of applicable law or the rules of the Trading Market. No liquidated damages, default interest, premium, cash settlement or enhanced conversion right shall arise under this Certificate of Designation by reason of a conversion being prohibited or delayed under Section 5(d).

iv. Reserved.

v. Reservation of Shares Issuable Upon Conversion. The Corporation covenants that, subject to receipt of the Stockholder Approval, it will reserve and keep available out of its authorized and unissued shares of Common Stock, for the sole purpose of issuance upon conversion of the Preferred Stock, not less than the aggregate number of shares of Common Stock issuable upon conversion of the then outstanding shares of Preferred Stock, taking into account adjustments under Section 7 and disregarding the conversion limitations solely for purposes of determining the required reserve; provided that nothing in this Section 5(c)(v) shall permit any issuance prohibited by Section 5(d). All shares of Common Stock so issued shall be duly authorized, validly issued, fully paid and nonassessable.

vi. Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon conversion of the Preferred Stock. The aggregate number of Conversion Shares issuable pursuant to Section 5(a) shall be rounded down to the nearest whole share. No cash settlement shall be payable in lieu of a fractional share.

vii. Transfer Taxes and Expenses. The issuance of Conversion Shares on conversion of the Preferred Stock shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such Conversion Shares, provided that the Corporation 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 Preferred Stock and the Corporation shall not be required to issue or deliver such Conversion Shares unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid. In the event that the Holder requests same-day processing for a Notice of Conversion, such Holder shall pay all Transfer Agent fees required for such same-day processing and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Conversion Shares.

d) Stockholder Approval; Absolute Blocker. Notwithstanding anything to the contrary in this Certificate of Designation or any Transaction Document, (i) no Common Stock or Preferred Stock shall be issued in excess of the amount authorized by the Corporation’s Certificate of Incorporation or the maximum amount permitted without the requisite stockholder approval under applicable Nasdaq Listing Rules, including Rules 5635(a), (b) and (d), as applicable, and (ii) no Preferred Stock shall be convertible into Common Stock, and no voting rights arising from such conversion may be exercised, unless and until Stockholder Approval has been obtained and the Stockholder Approval Effective Time has occurred. This blocker is absolute and applies to the Seller Parties (as defined in the Transaction Agreement), their Affiliates and all subsequent holders, including upon any upstream distribution, transfer or pledge. No cash settlement, waiver or other arrangement may circumvent this blocker, and any amendment of this Section 5(d) shall be effected only in accordance with the Delaware General Corporation Law and the rules of the Trading Market.

Section 6. Reserved.

Section 7. Certain Adjustments.

a) Stock Dividends and Stock Splits. If the Corporation, at any time while the Preferred Stock is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions that are payable in shares of Common Stock on shares of Common Stock (which, for the avoidance of doubt, shall not include any shares of Common Stock issued by the Corporation upon conversion of the Preferred Stock), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Corporation, then the number of Conversion Shares issuable pursuant to Section 5(a) shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately after such event, and of which the denominator shall be the number of shares of Common Stock outstanding immediately before such event. Any adjustment made pursuant to this Section 7(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification. Any distribution received or receivable by a Holder (including any distribution held in abeyance) pursuant to Section 2 or Section 7(d) shall not also give rise to an adjustment under this Section 7(a) with respect to the same Preferred Stock to the extent that would duplicate the economic benefit of that distribution.

b) Reserved.

c) Reserved.

d) Pro Rata Distributions. During such time as the Preferred Stock is outstanding, any dividend or other distribution on the Common Stock shall be governed by Section 2, without duplication. Any securities otherwise distributable in excess of the limitations in Section 5(d) shall be held in abeyance for the applicable Holder until, and only to the extent that, delivery is permitted under those provisions, without any cash substitute or preferential return.
