Until the Series C Preferred Stock are converted into Common Stock in accordance with Section 6 hereof, or except as otherwise provided by the DGCL, other applicable law or as provided in this Certificate of Designation, the holders of Series C Preferred Stock shall not be entitled to vote (or render written consents) on any matter submitted for a vote of (or written consents in lieu of a vote as permitted by the DGCL, the Certificate of Incorporation and the Bylaws) holders of Common Stock. Following the date on which the Series C Preferred Stock are convertible under Section 6 hereof, except as otherwise provided herein or as required by applicable law, Holders of the Series C Preferred Stock shall be entitled to vote with holders of the Common Stock on all matters that such holders of Common Stock are entitled to vote upon, in the same manner and with the same effect as the holders of Common Stock, voting together with the holders of Common Stock as a single class. Each share of Series C Preferred Stock shall entitle the Holder thereof to cast that number of votes per share of Series C Preferred Stock on an as converted to Common Stock basis. Notwithstanding the foregoing, to the extent that under the DGCL the vote of the holders of the Series C Preferred Stock, voting separately as a class or series, as applicable, is required to authorize a given action of the Corporation, the affirmative vote or consent of the Requisite Holders, voting together in the aggregate and not in separate series unless required under the DGCL, represented at a duly held meeting at which a quorum is present or by written consent of the Requisite Holders (except as otherwise may be required under the DGCL), shall constitute the approval of such action by the class or the series, as applicable. For the avoidance of doubt, following the date on which the Series C Preferred Stock are convertible under Section 6 hereof, for purposes of determining the presence of a quorum at any meeting of the stockholders of the Corporation at which the shares of Series C Preferred Stock are entitled to vote, the number of shares of Series C Preferred Stock and votes represented by such shares shall be counted on an as converted to Common Stock basis. Following the date on which the Series C Preferred Stock are convertible under Section 6 hereof, Holders of the Series C Preferred Stock shall be entitled to written notice of all stockholder meetings or written consents (and copies of proxy materials and other information sent to stockholders) with respect to which they would be entitled to vote, which notice would be provided pursuant to the Bylaws and the DGCL.

So long as any shares of Series C Preferred Stock are outstanding, the Corporation shall not, without first obtaining the approval of the Requisite Holders:

Section 4. Dividends

The shares of Series C Preferred Stock shall not have or confer, and the holders of the outstanding shares of Series C Preferred Stock shall not have, any right or entitlement to receive or otherwise participate in any dividend or distribution declared or paid by the Board of Directors or the Corporation, and no dividend shall accrue or be payable on any shares of Series C Preferred Stock or the Conversion Shares.

Section 5. Liquidation Preference

The Series C Preferred Stock shall rank (i) senior to all of the Common Stock; (ii) senior to any class or series of capital stock of the Corporation hereafter created specifically ranking by its terms junior to the Series C Preferred Stock (“Junior Securities”); and (iii) on parity with any other class or series of capital stock of the Corporation hereafter created specifically ranking by its terms on parity with the Series C Preferred Stock (“Parity Securities”), in each case, as to distributions of assets upon liquidation, dissolution or winding up of the Corporation, whether voluntarily or involuntarily (each, a “Dissolution”).

Upon a Dissolution, each Holder shall be entitled to receive, prior and in preference to any distributions of any of the assets or surplus funds of the Corporation (other than distributions that would otherwise constitute dividends) to the holders of the Common Stock and Junior Securities and pari passu with any distribution to the holders of Parity Securities, an amount per share of Series C Preferred Stock held by such Holder equal to the greater of (i) the Stated Value, or (ii) such amount per share as would have been payable had all shares of Series C Preferred Stock been converted into Common Stock pursuant to Section 6 at the then applicable Conversion Price immediately prior to such Dissolution. If, upon any such Dissolution, the assets of the Corporation shall be insufficient to pay the holders of shares of the Series C Preferred Stock the amount required under the preceding sentence, the holders of shares of Series C Preferred Stock and the holders of shares of Parity Securities shall share in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares of Series C Preferred Stock and any Parity Securities held by them upon such distribution if all amounts payable on or with respect to such shares of Series C Preferred Stock and Parity Securities were paid in full. For the avoidance of doubt, but without limiting the foregoing, neither a change in control of the Corporation, the merger or consolidation of the Corporation with or into any other entity, nor the sale, lease, exchange or other disposition of all or substantially all of the Corporation’s assets shall, in and of itself, be deemed to constitute a Dissolution.

Section 6. Conversion Rights

Effective at 5:00 pm Eastern Time (the “Conversion Time”) on the first Trading Day following receipt of Stockholder Approval (the “Conversion Date”), subject to adjustment as provided in Section 6(d), each outstanding share of Series C Preferred Stock shall automatically convert into that number of fully paid and nonassessable shares of Common Stock equal to the number obtained by dividing (i) the Stated Value of such Series C Preferred Stock by (ii) the Conversion Price in effect at the Conversion Time (determined as provided in this Section 6) (any such shares, “Conversion Shares”). The shares of Series C Preferred Stock that are converted pursuant to this Section 6(a) are referred to as the “Converted Stock.” Upon receipt of Stockholder Approval, the Series C Blocker shall cease to apply. In no event shall the Series C Preferred Stock convert into shares of Common Stock prior to the Stockholder Approval or in excess of the Maximum Number of Conversion Shares.

Fractional shares of Common Stock may not be issued in connection with any conversion of the Series C Preferred Stock. As to any fraction of a share which a Holder would otherwise be entitled to receive upon such conversion, the Corporation shall, at its election, either (i) pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price or (ii) round up to the next whole share.

If the Corporation or any Subsidiary thereof, at any time while shares of Series C Preferred Stock are outstanding, shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents, at an effective price per share less than the Conversion Price then in effect (such lower price, the “Base Share Price”, and each such issuance, a “Dilutive Issuance”) (the foregoing shall not include any Exempt Issuance), then simultaneously with the consummation (or, if earlier, the announcement) of each Dilutive Issuance, the Conversion Price shall be adjusted pursuant to the following formula:

CP2 = CP1 × (A + B) ÷ (A + C)

where:

CP2 = the Conversion Price in effect immediately after such Dilutive Issuance;

CP1 = the Conversion Price in effect immediately prior to such Dilutive Issuance;

A = the number of shares of Common Stock outstanding immediately prior to such Dilutive Issuance (including shares of Common Stock issuable upon conversion or exercise of all then-outstanding convertible or exercisable securities, including the Series C Preferred Stock);

B = the number of additional shares of Common Stock which would have been issued if such shares of Common Stock or Common Stock Equivalents had been issued at a price per share equal to CP1 (i.e., the aggregate consideration received by the Corporation for such Dilutive Issuance divided by CP1); and

C = the number of additional shares of Common Stock actually issued or issuable in connection with such Dilutive Issuance.

Whenever the Conversion Price is adjusted pursuant to this Section 6, the Corporation shall promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment. In addition, if the Corporation shall at any time prior to the conversion of all of the Series C Preferred Stock propose (i) to declare any dividend or distribution on the Common Stock or to offer the holders of Common Stock any additional rights, (ii) to effect any reclassification or recapitalization of the Common Stock, or (iii) to merge or consolidate with or into any other corporation, or sell, lease or convey all or substantially all of its property or business, or to liquidate, dissolve or wind up, then, in connection with each such event, the Corporation shall deliver to each Holder at least twenty (20) days prior to the applicable record or effective date therefor, a notice stating (A) the date on which a record is to be taken for the purpose of such dividend, distribution, or rights, or, if a record is not to be taken, the date as of which the holders of record of Common Stock to be entitled to such dividend, distribution, or rights are to be determined, and (B) the date on which any such reclassification, recapitalization, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable upon such reclassification, recapitalization, reorganization, consolidation, merger, sale, transfer, dissolution, liquidation or winding up.

The Corporation shall at all times when the Series C Preferred Stock shall be outstanding reserve and keep available out of its authorized but unissued shares of Common Stock, for the purpose of effecting the conversion of the Series C Preferred Stock, such number of its duly authorized shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Series C Preferred Stock. If at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Series C Preferred Stock, the Corporation shall take such corporate action as may be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to the Certificate of Incorporation. Before taking any action which would cause an adjustment reducing the Conversion Price below the then par value of the shares of Common Stock issuable upon conversion of the Series C Preferred Stock, the Corporation shall take any corporate action which may, in the opinion of its counsel, be necessary in order that the Corporation may validly and legally issue fully paid and nonassessable shares of Common Stock at such adjusted Conversion Price.

Section 7. Waiver

Notwithstanding anything to the contrary herein, any provisions of this Certificate of Designation may be waived on behalf of all of the holders of Series C Preferred Stock by the affirmative written consent or vote of the Requisite Holders.

Section 8. Director Nomination Rights

BladeRanger shall have the right, but not the obligation, to designate one (1) individual (the “Preferred Investor Designee”) to be nominated, elected, or appointed to the Board of Directors as provided below in Section 8(b). The Board of Directors shall consist of seven (7) directors, of which four (4) shall be “independent” as defined under Nasdaq listing standards. The Corporation shall take all necessary action to cause the Preferred Investor Designee to be nominated for election or appointed, as applicable, to the Board of Directors promptly following the Closing (as defined in the SPA).

Any Preferred Investor Designee designated by BladeRanger must (i) satisfy all qualifications, legal requirements and policies applicable to members of the Board of Directors generally, including any requirements under the DGCL, applicable securities laws and stock exchange rules, (ii) to the extent required by applicable Nasdaq listing standards for committee membership, qualify as an “independent” director under such standards, and (iii) not be a Person who has been involved in any of the events enumerated in Item 2(d) or Item 2(e) of Schedule 13D under the Exchange Act or Item 401(f) of Regulation S-K under the Securities Act, or is subject to any order, judgment, or decree of any court of competent jurisdiction or governmental authority permanently or temporarily enjoining or otherwise limiting such Person from acting as an investment adviser, underwriter, broker, dealer, entity, or in any other capacity in the securities industry. The Corporation and BladeRanger shall cooperate in good faith to ensure that the Preferred Investor Designee meets all applicable qualifications and that the nomination and appointment process complies with applicable law and the Corporation’s organizational documents.

Any Preferred Investor Designee (or any successor or replacement thereof) designated by BladeRanger pursuant to this Section 8 may be removed (with or without cause) only by BladeRanger. In the event of any vacancy in a directorship held by a Preferred Investor Designee (whether by reason of death, resignation, removal, or otherwise), BladeRanger shall have the exclusive right to designate a replacement director, subject to the qualification requirements of Section 8(b), to fill such vacancy, and the Corporation shall take all necessary action to cause such replacement director to be appointed promptly.

The rights set forth in this Section 8 shall continue during the Designation Period (as defined in Section 4.7(a) of the SPA) and shall terminate upon the expiration of such Designation Period. For the avoidance of doubt, conversion of the Series C Preferred Stock into Common Stock shall not, in and of itself, terminate such rights.

Section 9. Anti-Dilution Covenant

From and after the Closing (as defined in the SPA) until such time as all outstanding shares of Series C Preferred Stock are convertible into shares of Common Stock (whether by reason of Stockholder Approval or otherwise), the Corporation shall not issue, or enter into any agreement, arrangement or understanding to issue, any equity securities or equity-linked securities (including, without limitation, convertible notes, warrants, options, or other rights to acquire equity securities) without the prior written consent of the Requisite Holders; provided, however, that the foregoing restriction shall not apply to any Exempt Issuance; provided, further, that nothing in this Section 9 shall limit or modify any consent or other rights of BladeRanger under the SPA, including with respect to any issuance requiring BladeRanger’s prior written consent pursuant thereto.

Section 10. Amendments

This Certificate of Designation may be amended only by the affirmative written consent of the Requisite Holders and the Corporation.

Section 11. Notices
