(a) Capacity; Authority. The Purchaser is a natural person who has the right, power and legal capacity to enter into and deliver the Agreement and the other Transaction Documents and to consummate the Contemplated Transactions and otherwise to carry out his obligations hereunder and thereunder. The execution and delivery of this Agreement and each of the other Transaction Documents by the Purchaser and the consummation by him of the Contemplated Transactions have been authorized by all necessary action. Each Transaction Document to which he is a party has been duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms hereof or thereof, will constitute the valid and legally binding obligation of the Purchaser, enforceable against him in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(b) Investment Intent; Understandings or Arrangements. The Purchaser is acquiring the Securities in compliance with applicable securities laws, and in the ordinary course of his business. The Purchaser further represents that he is purchasing the Securities solely for his own account (and not for the account of any other Person except as contemplated in Section 5.6) for investment and not with a view to or for sale in connection with any distribution of the Securities or any portion thereof, and, except as contemplated in Section 5.6, not with any present intention of selling, offering to sell or otherwise disposing of or distributing the Securities or any portion thereof in any transaction other than a transaction exempt from registration under the Securities Act and any applicable state securities laws. Prior to the First Closing, Purchaser does not beneficially own, director or indirectly, any shares of Common Stock, Common Stock Equivalents or other Company securities. The Purchaser also represents that the entire legal and beneficial interest of the Securities is being purchased, and will be held, for the Purchaser’s account only (and not for the account of any other Person except as contemplated in Section 5.6), and neither in whole or in part for any other person. The Purchaser understands and acknowledges that (i) the Securities are “restricted securities” as the sale of the Securities in the Investment has not been registered under the Securities Act or under any applicable state securities law or laws of any other jurisdiction and the Securities must be held indefinitely unless subsequently registered under the Securities Act or an exemption from such registration is available and the Company is under no obligation to register the Securities, (ii) the Securities whether held in book-entry form or certificated form will have transfer restrictions and include the legend as provided in Section 4.1; and (iii) the Company will make a notation in its records and that of its transfer agent of the aforementioned restrictions on transfer and legends. The Purchaser further acknowledges that he will have reporting and disclosure obligations under the Exchange Act as a result of his investment in the Securities, including becoming an “Insider” for purposes of the Exchange Act and will become subject to the Company’s insider trading policy.

19

(c) Purchaser Status. At the time the Purchaser was offered the Securities, he was, and as of the date hereof he is an “accredited investor” as defined in any of Rule 501 (a)(4), (a)(5), or (a)(6) under the Securities Act. In addition, if Purchaser has purchased the Securities pursuant to Regulation S, the Purchaser represents and warrants that: (i) at the time he was offered the Securities he was not, as of such date and he is not, and throughout the Closing Date for the Second Closing he will continue not to be, a “U.S. Person” as that term is defined in Rule 902 of Regulation S; (ii) he has, and will at all times have, executed all documents (including this Agreement and the other Transaction Documents) outside of the United States; (iii) he was outside of the United States when offered the Securities and will be outside of the United States when initiating any Closing and on any Closing Date; and (iv) the Purchaser is not acquiring the Securities for the account or benefit of any “U.S. Person” as that term is defined in Rule 902 of Regulation S.

The Purchaser realizes that the purchase of the Securities will be a highly speculative investment which involves a high degree of risk, and the Purchaser is able to bear, without impairing his financial condition, to hold the Securities for an indefinite period of time and to suffer the economic risk of the Investment in the Securities and is able to afford a complete loss of such Investment without impairing his financial condition.

20

(f) Access to Information. The Purchaser acknowledges that he has had the opportunity to review the Transaction Documents (including all exhibits and schedules thereto) and the SEC Reports and has been afforded, (i) the opportunity to ask such questions as he has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable him to evaluate the Investment, including information about the Company’s remaining assets; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the Investment. The Purchaser understands that no U.S. or non-U.S. securities regulator or other authority has made any determination or finding relating to the merits or fairness of an investment in the Securities.

(h) Director Independence. A sufficient number of the Purchaser Nominees recommended by the Purchaser shall satisfy the criteria of “independence” under the rules and regulations of Nasdaq and applicable securities laws, so that the Company shall continue to be in compliance with such rules, regulations and laws following the appointment of the Purchaser Nominees.

(i) Purchaser Jurisdiction. The Purchaser has satisfied the full observance of the laws of the jurisdiction to which he is subject in connection with any invitation to subscribe for the Securities, including (i) the legal requirements within the Purchaser’s jurisdiction for the purchase of the Securities; (ii) any foreign exchange restrictions applicable to such purchase; (iii) any governmental or other consents that may need to be obtained; and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale, or transfer of the Securities. The Purchaser’s purchase and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of the Purchaser’s jurisdiction of citizenship, residency or domicile.

21

(j) Financial Sufficiency. The Purchaser shall at all times as of and after the Effective Date have sufficient cash on hand or other sources of immediately available funds (the “Purchaser Available Funds”) to enable him to timely fulfill and/or satisfy his payment and other financial obligations under this Agreement and the other Transaction Documents, including payment of the remaining Purchase Price at the Second Closing, his indemnification obligations. All of the Purchaser Available Funds shall not at any time be subject to any Lien. Purchaser represents that his assets comprising the Purchaser Available Funds, wherever located, whether in the U.S. or outside of the U.S., shall be available to satisfy his obligations under this Agreement regardless of where such assets are located and/or due to the Purchaser’s residency in the Republic of Panama or elsewhere.

The Company acknowledges and agrees that the representations contained in this Section 3.2 shall not modify, amend or affect the Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the Contemplated Transactions.

The indemnification required by this Section 4.12 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 are incurred. The indemnity agreements contained herein shall be in addition to any cause of action or similar right of any Company Party against the Purchaser or others and any liabilities the Purchaser may be subject to pursuant to law.

25

The indemnification required by this Section 4.13 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 are incurred.

27

(d) Following the First Closing, subject to obtaining Stockholder Approval on all matters as provided herein, and in reliance upon the Second Closing occurring as provided herein, the Purchaser shall have the right to recommend to the Company up to eight (8) individuals (collectively, the “Purchaser Nominees”) to be nominated for election at the Stockholders Meeting to serve as directors on the Board of Directors. The Purchaser and each Purchaser Nominee shall first be qualified and approved by the Company’s Nominating and Corporate Governance Committee, which shall include an assessment of each Purchaser Nominee’s qualifications and experience, personal and professional integrity, financial literacy and other factors and criteria customarily reviewed and assessed. The Purchaser shall recommend a sufficient number of Purchaser Nominees in order for the Company to satisfy the “independence” requirements as set forth in the Nasdaq Listing Rules and under the federal securities laws in order to be nominated to the Board of Directors. The Company shall coordinate the class in which the Purchaser and each Purchaser Nominee shall be nominated to serve on the Board of Directors in accordance with the Company’s certificate of incorporation and bylaws. The Purchaser and each Purchaser Nominee shall provide the requisite information for purposes of the evaluation of the Company’s Nominating and Corporate Governance Committee and required disclosure in the proxy statement for the Stockholders Meeting.

Notwithstanding the foregoing, the rights of the Purchaser provided in this Section 4.15(d) shall at all times be subject to, and in compliance with, Nasdaq Listing Rule 5640. In the event that Nasdaq informs the Company that it is not in compliance with Nasdaq listing requirements as a result of the Purchaser’s rights contained in this Agreement, the Purchaser shall cooperate with the Company to promptly remedy such non-compliance, including the possibility of proportionately reducing the Purchaser’s right to appoint the Purchaser Nominees hereunder.

4.16 Participation in Future Financing.

(a) Non-Underwritten Offerings.

(i) If, from the Effective Date until six (6) months after the Closing Date for the First Closing, (the “Participation Period”), the Company proposes to offer and sell any New Securities in an offering that is conducted pursuant to an exemption from registration under the Securities Act, or in an offering that is registered under the Securities Act that is not conducted as a firm-commitment underwritten offering, then, subject to compliance with all applicable securities laws and regulations, the Purchaser shall have the right to purchase, on the same terms, including the price per security, and subject to the same conditions, as are applicable to the other investors in such offering, that amount of New Securities being offered for sale in such offering equal to up to 25% of the total amount of New Securities offered for sale in such offering.

(ii) If the Company proposes to conduct an offering with respect to which the Purchasers would have rights to purchase New Securities pursuant to this Section 4.16, the Company shall give written notice (the “Offer Notice”) to the Purchaser at least three (3) Business Days prior to the commencement of the offering of the New Securities, stating (i) its bona fide intention to offer such New Securities, (ii) the number, type and material terms of such New Securities to be offered, (iii) the price and terms, if any, upon which it proposes to offer such New Securities and (iv) the estimated date and time at which the Company expects to enter into a definitive agreement for the sale of the New Securities (the “Expected Sale Date”).

If the Company receives no such notice from such Purchaser within the time period set forth herein, such Purchaser shall be deemed to have notified the Company that it does not elect to purchase any New Securities in connection with such offering and the Company shall be free to sell such securities in the offering.

28

(b) Underwritten Offerings. If, during the Participation Period, the Company proposes to offer and sell any New Securities in a firm commitment underwritten offering registered under the Securities Act, then, subject to compliance with all applicable securities laws and regulations, the Company will use its commercially reasonable efforts to cause the managing underwriter(s) of such offering to contact the Purchasers about potentially participating in such offering and to provide to the Purchasers, on the same terms, including the price per security, and subject to the same conditions, as are applicable to the public in such offering, the opportunity to purchase that amount of New Securities being offered for sale in such offering equal to up to 25% of the total amount of New Securities offered for sale in such offering (excluding securities issuable to the underwriter(s) of the offering upon exercise of an overallotment or other option to purchase additional shares).

(c) General Terms Applicable to Participation Rights.

If, by the tenth (10th) Business Day following delivery of notice of the offering to the Purchasers pursuant to this Section 4.16, no public disclosure regarding a transaction with respect to the applicable offering has been made, such offering shall be deemed to have been abandoned and the Purchaser shall be deemed to not be in possession of any material non-public information (as defined under the applicable securities laws) with respect to the proposed offering, unless the Company advises the Purchaser that the offering has not been abandoned. The Company understands and confirms that the Purchaser may rely on this Section 4.16 when effecting transactions in securities of the Company.

(ii) Subject to compliance with all applicable securities laws and regulations, the Purchaser may apportion any New Securities to be purchased pursuant to its rights in this Section 4.16 in such proportion as they deem appropriate among themselves and any of their respective affiliates.

(iv) The Company and the Purchaser hereby acknowledge that nothing in this Section 4.16 constitutes an offer or the commitment by any Person to purchase any New Securities in any offering.

SECTION 5 Liquidation Preference.

(a) Ranking. The Series AAA 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 any Series AAA Preferred Stock (“Junior Securities”); (iii) on parity with the Series AA Preferred Stock or any other class or series of capital stock of the Corporation hereafter created specifically ranking by its terms on parity with the Series AAA Preferred Stock (“Parity Securities”); and (iv) junior to the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and any class or series of capital stock of the Corporation hereafter created specifically ranking by its terms senior to any Series AAA Preferred Stock (“Senior 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”).

(b) Distribution to Series AAA Preferred Stock and Parity Securities. Subject to the prior and superior rights of the holders of any Senior Securities of the Corporation, 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 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 AAA Preferred Stock held by such Holder equal to the greater of (i) the Stated Value, plus any dividends declared but unpaid on such share of Series AAA Preferred Stock, or (ii) such amount per share as would have been payable had all shares of Series AAA Preferred Stock been converted into Common Stock pursuant to Section 6 (without regard to any restrictions on conversion) 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 AAA Preferred Stock the amount required under the preceding sentence, the holders of Series AAA 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 AAA Preferred Stock and Parity Securities held by them upon such distribution if all amounts payable on or with respect to such shares of Series AAA Preferred Stock and Parity Securities were paid in full. For the avoidance of any 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.

B-4

SECTION 6 Conversion Rights.

(a) General. Subject to and upon compliance with the provisions of this Section 6 and subject to the Corporation’s stockholders approving each of (A) an increase in the number of authorized shares of Common Stock to enable the Corporation to issue all of the shares of Common Stock that are issuable upon the conversion of the Series AAA Preferred Stock and any Series AA Preferred Stock that is issued and outstanding and (B) the conversion of the Series AAA Preferred Stock and any Series AA Preferred Stock that is issued and outstanding into shares of Common Stock in accordance with the listing rules of the Nasdaq Stock Market (the “Stockholder Approvals”), and subject to the Corporation filing an amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Charter Amendment”) evidencing such stockholder approval, each Holder shall be entitled, at its option, at any time and from time to time after the Stockholder Approvals and the filing of the Charter Amendment, to convert all or any such shares of Series AAA Preferred Stock into the number of fully paid and nonassessable shares of Common Stock equal to the number obtained by dividing (i) the Stated Value of such Series AAA Preferred Stock by (ii) the Conversion Price in effect at the Conversion Time (determined as provided in this Section 6).

(b) Fractions of Shares. Fractional shares of Common Stock may not be issued in connection with any conversion of the Series AAA Preferred Stock. As to any fraction of a share which a Holder would otherwise be entitled to receive upon such conversion, the Corporation shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price.

(c) Adjustments to Conversion Price.

(i) Upon Subdivisions. If, at any time after the date the first share of Series AAA Preferred Stock was issued, the number of shares of Common Stock outstanding is increased by a subdivision of shares of Common Stock, then, following the record date for the determination of holders of Common Stock affected by such subdivision, the Conversion Price in effect immediately before such subdivision shall be proportionately decreased so that the number of shares of Common Stock issuable on conversion of Series AAA Preferred Stock shall be increased in proportion to such increase in outstanding shares of Common Stock.

(ii) Upon Combinations. If, at any time after the date the first share of Series AAA Preferred Stock was issued, the number of shares of Common Stock outstanding is decreased by a combination of the outstanding shares of Common Stock into a smaller number of shares of Common Stock, then, following the record date to determine shares affected by such combination, the Conversion Price in effect immediately before such combination shall be proportionately increased so that the number of shares of Common Stock issuable on conversion of each share of Series AAA Preferred Stock shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

(iii) Stock Dividends. If, at any time after the date the first share of Series AAA Preferred Stock was issued, the Corporation shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable on the Common Stock in additional shares of Common Stock, then and in each such event the Conversion Price in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Conversion Price then in effect by a fraction: (1) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to the time of such issuance or the close of business on such record date, and (2) the denominator of which shall be the total number of shares of Common Stock outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution. Notwithstanding the foregoing, (a) if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Conversion Price shall be adjusted pursuant to this Section 6(c)(iii) as of the time of actual payment of such dividends or distributions; and (b) no such adjustment shall be made if the holders of Series AAA Preferred Stock simultaneously receive a dividend or other distribution of shares of Common Stock in a number equal to the number of shares of Common Stock as they would have received if all outstanding shares of Series AAA Preferred Stock had been converted into Common Stock on the date of such event.

B-5

(iv) Reorganization, Reclassification, Merger or Consolidation. If at any time or from time to time there shall be a reorganization, recapitalization, reclassification, merger or consolidation involving the Corporation in which the Common Stock is converted into or exchanged for securities, cash or property (other than a subdivision or combination provided for elsewhere in this Section 6), then, as a part of such reorganization, recapitalization, reclassification, merger, or consolidation, provision shall be made so that holders of Series AAA Preferred Stock shall thereafter be entitled to receive upon conversion of the Series AAA Preferred Stock, the kind and amount of shares of stock, cash or other property to which such holder would have been entitled if such holder had converted its shares of Series AAA Preferred Stock immediately prior to such reorganization, recapitalization, reclassification, merger or consolidation. In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 6 with respect to the rights of the holders of the Series AAA Preferred Stock after the reorganization, recapitalization, reclassification, merger or consolidation, to the end that the provisions of this Section 6 (including provisions with respect to changes in and other adjustments of the Conversion Price then in effect for the Series AAA Preferred Stock) shall be applicable after that event in as nearly equivalent a manner as may be practicable.

(d) Exercise of Conversion Privilege. In order to exercise the conversion privilege, the holder of any share of Series AAA Preferred Stock shall, (i) provide written notice in the form attached hereto as Annex A (a “Conversion Notice”) to the Corporation at any office or agency of the Corporation maintained for such purpose, that the Holder elects to convert all such shares of Series AAA Preferred Stock or, if less than the entire amount thereof is to be converted, the portion thereof to be converted and (ii) if such Holder’s shares are certificated, surrender the certificate evidencing such shares of Series AAA Preferred Stock, duly endorsed or assigned to the Corporation in blank, at such office or agency. The Conversion Notice shall state such Holder’s name or the names of the nominees in which such Holder wishes the shares of Common Stock to be issued. Series AAA Preferred Stock shall be deemed to have been converted immediately prior to the close of business on the date of surrender of such shares of Series AAA Preferred Stock for conversion in accordance with the foregoing provisions or such later time as specified in the Conversion Notice (the “Conversion Time”), and the shares of Common Stock issuable upon conversion of the specified shares shall be deemed to be outstanding of record as of such Conversion Time. As promptly as practicable on or after the Conversion Time, the Corporation shall (i) issue and shall deliver a certificate or certificates for the number of full shares of Common Stock issuable upon conversion (or a notice of such issuance if uncertificated shares are issued) and (ii) pay all declared but unpaid dividends on the shares of Series AAA Preferred Stock converted. In the case of any certificate evidencing shares of Series AAA Preferred Stock that is converted in part only, upon such conversion the Corporation shall also execute and deliver a new certificate evidencing the number of shares of Series AAA Preferred Stock that are not converted (or a notice of such issuance if uncertificated shares are issued).

(e) Notice of Adjustment of Conversion Price. Whenever the provisions of Section 6(c) require that the Conversion Price be adjusted as herein provided, the Corporation shall compute the adjusted Conversion Price in accordance with Section 6(c) and shall prepare a certificate signed by the Corporation’s principal executive officer or principal financial officer setting forth the adjusted Conversion Price and showing in reasonable detail the facts upon which such adjustment is based, and such certificate shall forthwith be filed at each office or agency maintained for such purpose for conversion of shares of Series AAA Preferred Stock and mailed by the Corporation at its expense to all holders of Series AAA Preferred Stock at their last addresses as they shall appear in the stock register.

(g) Corporation to Reserve Common Stock. Following the receipt of Stockholder Approvals and the filing of the Charter Amendment, the Corporation shall at all times reserve and keep available, free from preemptive rights, out of the authorized but unissued Common Stock or out of the Common Stock held in treasury, for the purpose of effecting the conversion of Series AAA Preferred Stock, the full number of shares of Common Stock issuable upon the conversion of all outstanding shares of Series AAA Preferred Stock. Before taking any action that would cause an adjustment reducing the Conversion Price below the then par value (if any) of the shares of Common Stock deliverable upon conversion of the Series AAA Preferred Stock, the Corporation will take any corporate action that, in the opinion of its counsel, is necessary in order that the Corporation may validly and legally issue fully paid and non-assessable shares of Common Stock at such adjusted Conversion Price.

B-6

(h) Taxes on Conversions. The Corporation will pay any and all original issuance, transfer, stamp and other similar taxes that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Series AAA Preferred Stock pursuant hereto. The Corporation shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock in a name other than that of the holder of the share(s) of Series AAA Preferred Stock to be converted (nor shall the Corporation be responsible for any other taxes payable by the holders of the Series AAA Preferred Stock), and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Corporation the amount of any such tax or has established to the satisfaction of the Corporation that such tax has been paid.

SECTION 7 Waiver. Notwithstanding anything to the contrary herein, any provisions of this Certificate of Designations may be waived on behalf of all of the holders of Series AAA Preferred Stock by the affirmative written consent or vote of the Requisite Holders.

B-7

IN WITNESS WHEREOF, the Corporation has caused this Certificate of Designations, Preferences and Rights to be duly executed by its Chief Financial Officer, this [__] day of [________], 2025.
