Subject to and upon compliance with the provisions of this Section 4, the Series B Preferred Stock shall be convertible at the election of the Holder thereof into a number of fully paid and nonassessable shares of Common Stock determined in accordance with subparagraph (d) of this Section 4, at any time and from time to time.

(b) Automatic Conversion. Each outstanding share of Series B Preferred Stock shall automatically be converted, without any further act of the Corporation or its stockholders, into fully paid and nonassessable Common Stock at the Conversion Price then in effect (the “Automatic Conversion”) upon the earliest of:

(i) Automatic Conversion Date. The earlier of (x) the date on which the Company or a Subsidiary shall have consummated a merger with Serina Therapeutics, Inc., an Alabama corporation, or a subsidiary thereof; and (y) February 1, 2024, if such conversion is not limited by the 19.9% Cap or the 50% Cap in accordance with subparagraph (d) of this Section 4;

(ii) Alternate Automatic Conversion Date: If on the date specified in clause (i) of this paragraph (b) such conversion is limited by the 19.9% Cap or the 50% Cap in accordance with subparagraph (d) of this Section 4, then such conversion shall take place on the tenth day after such stockholder approvals have been obtained as may be required to permit such conversion without the limitations of the 19.9% Cap and the 50% Cap.

(iii) Vote. The Holders of at least a majority of the outstanding shares of the Series B Preferred Stock approve or consent to the Automatic Conversion, provided that such conversion is not then limited by the 19.9% Cap or the 50% Cap in accordance with subparagraph (d) of this Section 4.

(c) Valid Issuance. All Common Stock issued upon conversion of the Series B Preferred Stock will, upon issuance by the Corporation, be duly authorized and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof, and the Corporation shall take no action or fail to take any action which will cause a contrary result.

(d) Number of Shares Issuable Upon Conversion. Each share of Series B Preferred Stock shall be converted into the number of shares of Common Stock determined by dividing (x) a number equal to the number of dollars and cents comprising the Subscription Price, by (y) a number equal to the number of dollars and cents comprising the Conversion Price in effect on the Conversion Date. If under the rules of the Applicable Exchange, approval by the stockholders of the Corporation would be required in connection with the issuance of Common Stock in excess of the 19.9% Cap upon any conversion under this Section 4, then unless and until such stockholder approval has been obtained, the maximum number of shares of Common Stock that may be issued upon conversion of all shares of Series B Preferred Stock in the aggregate shall be an amount equal to the 19.9% Cap. If under the rules of the Applicable Exchange, approval by the stockholders of the Corporation would be required in connection with the issuance of Common Stock in excess of the 50% Cap upon any conversion under this Section 4, then unless and until such stockholder approval has been obtained, the maximum number of shares of Common Stock that may be issued to a Holder upon conversion of shares of Series B Preferred Stock shall be an amount that, when added to other shares of Common Stock owned by such Holder immediately prior to such conversion, would equal one share less than the 50% Cap.

(e) Mechanics of Conversion. The Holder of any Series B Preferred Stock may exercise the conversion right specified in paragraph (a) of this Section 4 by surrendering to the Secretary of the Corporation or any transfer agent of the Corporation the certificate or certificates for the shares to be converted, if such shares are certificated, accompanied by a Notice of Conversion. Upon the occurrence of the event specified in paragraph (b) of this Section 4, the outstanding Series B Preferred Stock shall be converted automatically without any further action by the Holder of such shares and whether or not the certificates representing such shares are surrendered to the Corporation or its transfer agent. Conversion shall be deemed to have been effected on the date when delivery of a Notice of Conversion and certificates for shares to be converted is made in the case of conversion under paragraph (a) of this Section 4 if Series B Preferred Stock is issued in certificated form, or on the date of the event specified in paragraph (b) of this Section 4, and such date is referred to herein as the “Conversion Date.” Subject to the provisions of subparagraph (g)(ii) of this Section 4, as promptly as practicable thereafter (and after surrender of the certificate or certificates evidencing Series B Preferred Stock to the Corporation or any transfer agent of the Corporation, if applicable) the Corporation shall issue and deliver to or upon the written order of such Holder a certificate or certificates for the number of shares of Common Stock to which such Holder is entitled and a check or cash with respect to any fractional interest in any share of Common Stock as provided in paragraph (f) of this Section 4. Subject to the provisions of subparagraph (g)(ii) of this Section 4, the person in whose name the certificate or certificates for Common Stock are to be issued shall be deemed to have become a holder of record of such Common Stock on the applicable Conversion Date. Upon conversion of only a portion of the number of shares covered by a certificate representing Series B Preferred Stock surrendered for conversion (in the case of conversion pursuant to paragraph (a) of this Section 4), as applicable, the Corporation shall issue and deliver to or upon the written order of the Holder of the certificate so surrendered for conversion, at the expense of the Corporation, a new certificate covering the number of shares of Series B Preferred Stock representing the unconverted portion of the certificate so surrendered, if such shares are to be held in certificated form. Notwithstanding the foregoing, the Corporation shall not be obligated to issue to any Holder of Series B Preferred Stock certificates evidencing the Common Stock issuable upon such conversion unless certificates evidencing the Series B Preferred Stock are delivered to either the Corporation or any transfer agent of the Corporation if such shares of Series B Preferred Stock are held in certificated form. No medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion shall be required.

(f) Fractional Shares. No fractional share of Common Stock or scrip shall be issued upon conversion of Series B Preferred Stock. If more than one share of Series B Preferred Stock shall be surrendered for conversion at any one time by the same holder, the number of shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of Series B Preferred Stock so surrendered. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of any Series B Preferred Stock, the Corporation shall pay a cash adjustment in respect of such fractional interest in an amount equal to that fractional interest at the then Fair Value.

(g) Conversion Price and Subscription Price Adjustments. If the Corporation shall (A) declare a dividend or make a distribution on its Common Stock in shares of Common Stock, (B) subdivide or reclassify the outstanding Common Stock into a greater number of shares, or (C) combine or reclassify the outstanding Common Stock into a smaller number of shares, the Conversion Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be proportionately adjusted. Successive adjustments in the Conversion Price shall be made whenever any event specified above shall occur. If the Corporation shall (i) declare a dividend or make a distribution on the Series B Preferred Stock in shares of Series B Preferred Stock, (ii) subdivide or reclassify the outstanding Series B Preferred Stock into a greater number of shares, or (iii) combine or reclassify the outstanding Series B Preferred Stock into a smaller number of shares, the Subscription Price in effect at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be proportionately adjusted. Successive adjustments in the Conversion Price or Subscription Price shall be made whenever any event specified above shall occur.

(i) Rounding of Calculations; Minimum Adjustment. All calculations under this Section 4(g) shall be made to the nearest cent or to the nearest one hundredth (1/100th) of a share, as the case may be. Any provision of this Section 4 to the contrary notwithstanding, no adjustment in the Conversion Price shall be made if the amount of such adjustment would be less than one percent (1%) of the Conversion Price, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate one percent (1%) of the Conversion Price or more. Notwithstanding the foregoing, the Board of Directors may elect at any time to make an adjustment otherwise required under this Section 4(g) of less than one percent (1%).

(ii) Timing of Issuance of Additional Common Stock Upon Certain Adjustments. In any case in which the provisions of this Section 4(g) require that an adjustment shall become effective immediately after a record date for an event, the Corporation may defer until the occurrence of such event (A) issuing to the Holder of any Series B Preferred Stock converted after such record date and before the occurrence of such event the additional Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment, and (B) paying to such Holder any amount of cash in lieu of a fractional share of Common Stock pursuant to paragraph (h) of this Section 4; provided that the Corporation upon request shall deliver to such Holder a due bill or other appropriate instrument evidencing such Holder’s right to receive such additional shares, and such cash, upon the occurrence of the event requiring such adjustment.

(h) Fair Value. The “Fair Value” per share of Common Stock for any date shall be determined by the Board of Directors as follows:

(i) If the Common Stock is listed on a national securities exchange, the Fair Value shall be the average of the last reported sale price of the Common Stock on such exchange, for the last twenty consecutive trading days prior to such date; or

(ii) If the Common Stock is not listed on a national securities exchange but prices for the Common Stock are reported on an interdealer automated quotation system, the Fair Value shall be the average of the daily high and low sales prices reported on such system during the last twenty consecutive trading days prior to such date; or

(iii) If the prices for the Common Stock cannot be determined under Section 4(h)(i) or Section 4(h)(ii), the Fair Value shall be an amount determined in such reasonable manner as may be prescribed by the Board of Directors in good faith, irrespective of any accounting treatment.

(i) Statement Regarding Adjustments. Whenever the Conversion Price or Subscription Price shall be adjusted as provided in paragraph (g) of this Section 4, the Corporation shall forthwith file, at the principal office of the Corporation, a statement showing in detail the facts requiring such adjustment and the Conversion Price or Subscription Price that shall be in effect after such adjustment, and the Corporation shall also cause a copy of such statement to be sent to each Holder in the manner for giving notices as provided herein. Where appropriate, such copy may be given in advance and may be included as part of a notice required to be mailed under the provisions of paragraph (j) of this Section 4.

(j) Notice to Holders of Series B Preferred Stock. If (i) the Corporation shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (ii) the Corporation shall declare a redemption of the Common Stock, (iii) the Corporation shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (iv) the approval of any stockholders of the Corporation shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Corporation is a party, any sale or transfer of all or substantially all of the assets of the Corporation (and all of its Subsidiaries, taken as a whole), or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (v) a voluntary or involuntary liquidation, dissolution or other winding up of the affairs of the Corporation shall be authorized, in each case, the Corporation shall cause to be sent to each Holder of Series B Preferred Stock at the last address of such Holder as it shall appear upon the stock books of the Corporation, at least twenty (20) calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (A) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined, or (B) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange, and (C) the amount of such dividend, distribution, redemption, rights or warrants per share to be distributed to holders of Common Stock; provided that the failure to deliver such notice or any defect therein or in the content, sending, or delivery of such notice shall not affect the validity of the corporate action required to be specified in such notice.

(k) Costs. The Corporation shall pay all documentary, stamp, transfer or other transaction taxes, if any, attributable to the issuance or delivery of Common Stock upon conversion of, any Series B Preferred Stock; provided that the Corporation shall not be required to pay any taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificate for such shares in a name other than that of the Holder of the Preferred Stock in respect of which such shares are being issued.

(l) Reservation of Shares. So long as any Series B Preferred Stock remain outstanding, the Corporation shall reserve at all times free from preemptive rights, out of its authorized but unissued Common Stock, solely for the purpose of effecting the conversion of the Series B Preferred Stock, sufficient Common Stock to provide for the conversion of all outstanding Series B Preferred Stock; and 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 Series B Preferred Stock, the Corporation will take such corporate action as may, in the opinion of counsel, 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, as applicable, this Certificate of Designation or the Corporation’s Certificate of Incorporation.

5. Voting Rights. The following matters shall require the approval of the holders of a majority of the Series B Preferred Stock then outstanding, voting as a separate class: (i) creation of any Preferred Stock ranking as Senior Stock to the Series B Preferred Stock with respect to liquidation preferences; (ii) repurchase of any shares of Junior Stock except shares issued pursuant to or in connection with a compensation or incentive plan or agreement approved by the Board of Directors for any officers, directors, employees or consultants of the Corporation; (iii) any sale, conveyance, or other disposition of all or substantially all the Corporation’s property or business, or any liquidation or dissolution of the Corporation, or a merger into or consolidation with any other corporation (other than a wholly-owned Subsidiary corporation) but only to the extent that the Delaware General Corporation Law, as the same may be amended from time to time, requires that such transaction be approved by each class or series of Preferred Stock; (iv) any adverse change in the powers, preferences and rights of, and the qualifications, limitations or restrictions on, the Series B Preferred Stock; or (v) any amendment of the Corporation’s Certificate of Incorporation or Bylaws that results in any adverse change in the powers, preferences and rights of, and the qualifications, limitations or restrictions on, the Series B Preferred Stock; provided, that nothing in this paragraph shall restrict or limit the rights and powers of the Board of Directors to fix by resolution the rights, preferences, and privileges of, and restrictions and limitations on, stock ranking as Parity Stock or Junior Stock to Series B Preferred Stock. Except as may otherwise be required by the Delaware General Corporation Law, as the same may be amended from time to time, the Series B Preferred Stock shall have no other voting rights.

8. Lost or Mutilated Stock Certificate.

The Corporation and each Holder irrevocably submits to the exclusive jurisdiction of the Delaware Courts for the adjudication of any Proceeding, and hereby irrevocably waives, and agrees not to assert in any Proceeding any claim that they are not personally subject to the jurisdiction of such Delaware Courts, or such Delaware Courts are an improper or inconvenient venue for such Proceeding. The Corporation and each Holder irrevocably waives personal service of process and consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to such party hereunder and agrees that such service shall constitute good and sufficient service of process and notice. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by applicable law. If the Corporation or any Holder shall commence a Proceeding, the prevailing party in such Proceeding shall be reimbursed by the other party for its attorneys’ fees and other costs and expenses incurred in the investigation, preparation and prosecution of such Proceeding.

10. Waivers. Any waiver of a breach of any term or provision hereof shall not operate as or be construed to be a waiver of any other breach of such term or provision or of any breach of any other provision hereof or a waiver by any other Holder. The failure of the Corporation or a Holder to insist upon strict adherence to any term or provision hereof on one or more occasions shall not be considered a waiver or deprive that party (or any other Holder) of the right thereafter to insist upon strict adherence to that term or provision or any other term or provision hereof on any other occasion. Any waiver by the Corporation or a Holder must be in writing.

11. Next Business Day. Whenever any notice, payment, action, or performance of any other obligation hereunder shall be due or required on a day other than a Business Day, such notice, payment, action, or performance shall be given, paid, taken, or performed, as applicable, on the next succeeding Business Day.

14. Status of Reacquired Shares. Shares of Series B Preferred Stock which have been issued and reacquired in any manner or which shall have been converted into Common Stock shall (upon compliance with any applicable provisions of the laws of the State of Delaware) have the status of authorized and unissued Preferred Stock of the Corporation undesignated as to series and may be redesignated as to series and reissued.
