(a) Ranking. The Series AA 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 AA Preferred Stock (“Junior Securities”); (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 AA 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 AA 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 AA 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 AA 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 AA Preferred Stock, or (ii) such amount per share as would have been payable had all shares of Series AA 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 AA Preferred Stock the amount required under the preceding sentence, the holders of Series AA 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 AA Preferred Stock and Parity Securities held by them upon such distribution if all amounts payable on or with respect to such shares of Series AA 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.

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 AA Preferred Stock and any Series AAA Preferred Stock, par value $0.001 per share (the “Series AAA Preferred Stock”), that is issued and outstanding and (B) the conversion of the Series AA Preferred Stock and any Series AAA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA Preferred Stock had been converted into Common Stock on the date of such event.

(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 AA Preferred Stock shall thereafter be entitled to receive upon conversion of the Series AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA 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 AA Preferred Stock converted. In the case of any certificate evidencing shares of Series AA 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 AA 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 AA Preferred Stock and mailed by the Corporation at its expense to all holders of Series AA 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 Approval 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 AA Preferred Stock, the full number of shares of Common Stock issuable upon the conversion of all outstanding shares of Series AA 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 AA 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.

(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 AA 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 AA Preferred Stock to be converted (nor shall the Corporation be responsible for any other taxes payable by the holders of the Series AA 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 AA Preferred Stock by the affirmative written consent or vote of the Requisite Holders.

IN WITNESS WHEREOF, the Corporation has caused this Certificate of Designations, Preferences and Rights to be duly executed by its Chief Financial Officer, this 24th day of November, 2025.

3.2 Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants as of the date of each Closing (unless such a representation is made as of a specific date therein, in which case, such representation shall be accurate as of that specific date):

(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.

(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 further represents that the Purchaser is not an “underwriter,” “distributor” or a “dealer” (each as defined in the Securities Act). Purchaser is presently a citizen of Israel and the E.U., a bona fide resident of the Republic of Panama, and has no present intention of becoming a resident of any other state, country or jurisdiction.

The Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or, to the knowledge of the Purchaser, any other general solicitation or general advertising. In addition, the Purchaser has not engaged, nor is he aware that any party has engaged, will not engage nor cause any third party to engage in, and is not purchasing the Securities as a result of any “directed selling efforts” (as defined in Rule 902(c) of Regulation S) in the United States.

(e) Experience of Purchaser. The Purchaser, either by reason of his extensive business and finance experience alone or together with the experience of the Purchaser’s professional advisors and representatives (who are unaffiliated with and who are not compensated by the Company or any of its Affiliates), has the requisite knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the Investment in the Securities and to protect the Purchaser’s own interests in connection with the Investment and the other Contemplated Transactions, and has so evaluated the merits and risks of such Investment and the other Contemplated Transactions. 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.

(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. In making its investment decision, the Purchaser has relied upon its review of the SEC Reports and other Company filings with the Commission and other documents and not any representation, oral or written, by the Company’s officers or directors.

(g) Certain Transactions and Confidentiality.

(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.

(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.

(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.

(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.

(i) Notwithstanding anything to the contrary in this Section 4.16 and unless otherwise agreed by the Purchaser, in the event the Company determines to abandon a proposed offering regarding which the Company or any underwriter have provided notice to the Purchaser pursuant to this Section 4.16, the Company shall, or shall cause the managing underwriter(s), to confirm such abandonment to the Purchaser in the same manner and on the same day as such abandonment is communicated to other potential investors. 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.

(iii) The rights of the Purchaser under this Section 4.16 to purchase securities in an offering will be conditioned upon the completion of such offering.

(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.

(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.

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.

(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.

(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.

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.

Exhibit 10.3

VOTING AGREEMENT

THIS VOTING AGREEMENT (this “Agreement”) is being signed on November 23, 2025 (the “Signature Date”) by and among (a) Kala Bio, Inc. a Delaware corporation whose Common Stock is listed for trading on the Nasdaq (the “Proxy” or the “Company”), (b) Mr. David Elliot Lazar, an individual (“Lazar”), and (c) OXFORD FINANCE LLC, a Delaware limited liability company (the “Stockholder”).

WHEREAS, the Company and Lazar are contemplating entering into a Securities Purchase Agreement (the “Securities Purchase Agreement”) that will provide for the sale and issuance of, inter alia, shares of newly designated series of Company preferred stock (“Preferred Stock”), which shares, among other rights, are expected to be convertible into shares of the Company’s common stock, par value $0.001 per share (“Common Stock”), subject to and in accordance with the terms of the Securities Purchase Agreement once finalized, and in connection with that Securities Purchase Agreement, the Stockholder desires to provide the Proxy with certain contractual rights as set forth below.

WHEREAS, the Stockholder hereby represents that it does not have any beneficial interest in capital stock of the Company and in any other shares or securities of the Company and/or any of its subsidiaries issued or issuable in respect thereof on and after the Signature Date, other than the 1,620,000 shares of common stock of the Company to be issued as described in the Loan Settlement Agreement of even date herewith.

NOW, THEREFORE, in consideration of the recitals set forth hereinabove and the mutual covenants and agreements herein contained, and other good and valuable consideration, the receipt and sufficiency of which are acknowledged hereby, each of the parties hereto, intending legally to be bound, hereby agrees as follows:

1. Incorporation of Recitals. The parties to this Agreement hereby agree and acknowledge that all of the Recitals set forth hereinabove are true, complete and correct in every respect and hereby incorporate said Recitals into this Agreement by this reference.

2. Representations of the Stockholder. The Stockholder hereby represents and warrants to the Proxy and Lazar that it: (a) has full power to enter into this Agreement and has not, prior to the Signature Date, executed and/or delivered any proxy or entered into any other voting agreement or similar arrangement and (b) will not take any action inconsistent with the purposes and provisions of this Agreement. Without limiting the above or anything otherwise in this Agreement, the Stockholder represents that neither it nor, any of its representatives or affiliates has (i) entered into (and, except with the prior written consent of the Proxy, agrees that it will not and will use reasonable efforts to ensure that its representatives and affiliates will not enter into) directly or indirectly, any agreement, arrangement or understanding with any person or firm as a principal, co-investor or co-bidder with respect to a possible transaction involving the Company or that would restrict the ability of any other person to provide debt, equity or other financing for a possible transaction involving the Company or (ii) engaged in any discussions which might lead to any agreement, arrangement or understanding with any such person or firm.

3. Escrow of Agreement. Upon execution of this Agreement, it shall be placed in escrow with counsel to Lazar, ABZ Law, until the complete execution and effectiveness of the Securities Purchase Agreement by the Company and Lazar, at which time this Agreement shall be released from such escrow to the benefit of the Proxy (the “Proxy Effective Date”).

4. Scope of Agreement. Upon and following the Proxy Effective Date, this Agreement pertains to the vote of the 1,620,000 shares of Common Stock, representing the aggregate voting interest of the Stockholder immediately following the Signature Date, as well as any additional shares of Common Stock which may be acquired by the Stockholder until the expiration of this Agreement (the “Proxy Shares”) by the Proxy with respect to any and all matters concerning a stockholder vote in respect of the Proxy Shares with respect to actions to be taken by the Company and recommended by the Board of Directors of the Company at its next special or annual meeting of stockholders.

In addition, upon and following the Proxy Effective Date, the Stockholder hereby agrees that, for a period of four (4) months from the Proxy Effective Date, unless such shall have been specifically invited in advance in writing by Lazar, neither the Stockholder, nor any of its representatives acting on its behalf, will in any manner, directly or indirectly: (i) effect or seek, offer or propose (whether publicly or otherwise) to effect, or cause or participate in or in any way advise, assist or encourage any other person to effect or seek, offer or propose (whether publicly or otherwise) to effect or participate in, (a) any acquisition of any securities (or beneficial ownership thereof) or assets of the Company, or any rights to acquire any such securities (including derivative securities representing the right to vote or economic benefit of any such securities) or assets; (b) any tender or exchange offer, merger or other business combination involving the Company; (c) any recapitalization, restructuring, liquidation, dissolution or other extraordinary transaction with respect to the Company; or (d) any “solicitation” of “proxies” (as such terms are used in the proxy rules of the Securities and Exchange Commission) or consents to vote any voting securities of the Company; (ii) form, join or in any way participate in a “group” (as defined under the 1934 Act) with respect to any securities of the Company; (iii) otherwise act, alone or in concert with others, to seek to control or influence the management, board of directors or policies of the Company; (iv) take any action which might force the Company to make a public announcement regarding any of the types of matters set forth in (i) above; (v) enter into any discussions or arrangements with any third party with respect to any of the foregoing; or (vi) request that the Company (or its directors, officers, employees or agents) amend or waive any provision of this paragraph (including this clause (vi)). Notwithstanding anything to the contrary contained in this paragraph (the “Standstill Provision”) a Stockholder shall be permitted to: 1) make proposals to the Company’s Board of Directors or special committee, the chairman of the Board of Directors and/or chief executive officer of the Company on a confidential, nonpublic basis for either (A) a proposed transaction between the parties, so long as Stockholder reasonably believes in good faith, based on the written advice of its outside counsel, that neither it nor the Company nor the Proxy would reasonably be expected to be required by applicable law, regulation or stock exchange requirement to disclose publicly any such proposal or (B) a waiver of this Section 4 and 2) dispose of Stockholder’s shares in the Company, whenever acquired on the open market, provided Stockholder shall not dispose of any shares owned as of the Signature Date until after it has voted its 1,620,000 shares of Common Stock at the applicable stockholders meeting as recommended by the Board of Directors of the Company (the “Approval”).

5. Changes in Capital Stock. In the event that subsequent to the Signature Date, any shares of capital stock or other securities the Company are issued on, or in exchange for, any of the Proxy Shares by reason of any stock dividend, stock split, consolidation of shares, reclassification, exchange, merger or consolidation or otherwise involving the Company, such shares of capital stock or other securities shall be deemed to be Proxy Shares for purposes of this Agreement.

6. Voting of Proxy Shares. The Stockholder agrees and covenants that at any meeting of the stockholders of the Company and/or in connection with any corporate action by the stockholders of the Company from the Signature Date until the termination of this Agreement, all of his/its respective shares of the Proxy Shares shall be voted by the Stockholder in favor of all proposals recommended by the Board of Directors of the Company that are presented for stockholder approval as set forth in Section 4 above or otherwise, provided that such proposal does not create liability of any nature of Stockholder and is otherwise compliant with all applicable legal requirements. The Stockholder agrees to promptly vote their Proxy Shares within seven (7) days after the Company files a definitive proxy statement for a meeting of its stockholders. To the extent that such shares are not voted, then the Stockholder grants the Company an irrevocable proxy, as provided in Section 7, to vote all of the Proxy Shares in the manner and to the effect determined by said Proxy in his sole and absolute discretion with respect to actions proposed to be taken by the Company. Accordingly, during the term of this Agreement, no Stockholder shall vote or attempt to vote any of his/its respective shares of the Proxy Shares, or otherwise exercise or attempt to exercise any voting or other approval rights of any of his/its respective shares of the Proxy Shares except as provided in this Section 6, and any such prohibited exercise by any Stockholder of voting or approval rights shall be void and of no force and effect.

7. Irrevocable Proxy.

(a) In order to give effect to and in furtherance of the agreements and covenants set forth in this Agreement, the Stockholder hereby irrevocably constitutes and appoints Proxy as proxy for such Stockholder, with full power of substitution, for and in the name and on behalf of such Stockholder, to vote any and all of his/its respective shares of Proxy Shares with regard to any question, action, resolution, election or other matter presented to the stockholders of the Company in favor of and/or approval with respect to actions proposed to be taken by the Company. Proxy shall vote said Proxy Shares in such manner and to such effect as the Proxy may determine in his sole and absolute discretion with respect to actions proposed to be taken. The proxy granted hereby shall remain in effect for so long as and at all times that this Agreement shall remain in effect. The proxy granted hereby is irrevocable and is coupled with an interest sufficient in law to support an irrevocable proxy.

(b) The Proxy hereby accepts its appointment as proxy of the Stockholder, pursuant to Subsection 7(a) of this Agreement. Other than as specifically set forth herein, the Proxy shall have no other rights with respect to the Proxy Shares.

(c) In no way shall the terms of this Agreement be interpreted in a way to cause a violation of Section 160(c) of the Delaware General Corporate Law or to prohibit, limit or restrict Proxy from exercising any fiduciary duties as an officer and/or director to the Company at and from such time as the Proxy may be such.

(d) The voting of Proxy Shares pursuant to this Agreement may be effected in person, by proxy, by written consent or in any other manner permitted by applicable law. For the avoidance of doubt, voting of the Proxy Shares pursuant to the Agreement need not make explicit reference to the terms of this Agreement.

8. Limitation of Proxy’s Liability. Proxy shall not incur any liability or responsibility by reason of any error of judgment, mistake of law or other mistake, or for any act or omission of any agent or attorney, or for any misconstruction of this Agreement, or for any action of any kind taken or omitted hereunder or believed by him to be in accordance with the provisions and intents hereof.

9. Consideration. In exchange for the Irrevocable Proxy and the transfer of the voting rights of the Stockholder, Lazar and the Company shall use all commercially reasonable efforts to 1) execute the Securities Purchase Agreement and undertake the actions contemplated therein, including the investment by Lazar in the Company and 2) cause the Cash Settlement to be paid in accordance with the Settlement Agreement.

10. Term.

(a) This Agreement shall commence on the Signature Date and continue for a period of four (4) months from the Proxy Effective Date, unless terminated by Proxy, in Proxy’s sole discretion.

(b) The Company and the Stockholder confirms hereby that he/it understands and acknowledges that this Agreement will continue for a period of four (4) months from the Proxy Effective Date as set forth above, unless terminated by Proxy, in Proxy’s sole discretion, and that the preceding part of this Section 10(b) reflects his/its intention.

11. Successor Proxy. In the event that the Proxy is unable or unwilling to serve as the Proxy, a successor proxy (who will become the Proxy under this Agreement, if appointed in accordance with this Section 11) may be appointed by the Proxy at its discretion, or if the Proxy is unable to make such appointment by the consent of the successors to the Company’s individual shares of capital stock that hold a majority interest in such shares. A successor proxy shall be vested with all the rights, powers and authority as if originally named in this Agreement.

12. Legend; Subsequent Holders of Proxy Shares. The Stockholder hereby acknowledges and agrees that commencing on the Signature Date and continuing for the term of this Agreement all certificates for the shares of Proxy Shares may, but need not, be imprinted by the Company with notice of this Agreement and the irrevocable proxy set forth herein. The Stockholder agrees not to transfer any interest in his/its respective Proxy Shares during the term of this Agreement, unless the transferee executes and delivers a joinder and adoption agreement pursuant to which transferee or assignee of Proxy Shares shall continue to be subject to the terms hereof and, as a condition precedent to any such transfer(s) (and the Company’s recognizing such transfer(s)), each such transferee or assignee shall agree in writing to be subject to each of the terms of this Agreement by executing and delivering such joinder and adoption agreement to the satisfaction of the Proxy. Upon the execution and delivery of by any transferee joinder and adoption agreement, such transferee shall be deemed to be a party hereto as if such transferee were the transferor and such transferee’s signature appeared on the signature pages of this Agreement and shall be deemed to be a Stockholder. A Stockholder shall not make, and the Company shall not permit, the transfer of Proxy Shares on its books or issue a new certificate representing any such Proxy Shares unless and until such transferee (or group) shall have complied with the terms of this Section 12.

13. Governing Law; Jurisdiction and Venue. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to rules regarding choice of law. EACH PARTY HERETO AGREES TO SUBMIT TO THE PERSONAL JURISDICTION AND VENUE OF THE STATE AND/OR FEDERAL COURTS LOCATED IN WILMINGTON, DELAWARE FOR RESOLUTION OF ALL DISPUTES ARISING OUT OF, IN CONNECTION WITH, OR BY REASON OF THE INTERPRETATION, CONSTRUCTION, AND ENFORCEMENT OF THIS AGREEMENT AND/OR ANY ADOPTION AGREEMENT, AND HEREBY WAIVES THE CLAIM OR DEFENSE THEREIN THAT SUCH COURTS CONSTITUTE AN INCONVENIENT FORUM.

14. Benefits; Binding Effect. This Agreement shall be for the benefit of and binding upon the parties hereto and their respective heirs, personal representatives, legal representatives, successors, assigns and transferees.

15. Counterparts. This Agreement may be executed in several counterparts, and all so executed shall constitute one Agreement, binding on all the parties hereto, notwithstanding that all the parties are not signatories to the original or same counterpart.

16. Amendment or Modification. This Agreement may be altered, modified or amended only by the unanimous consent, in writing, of the parties hereto, either now or hereafter. Any such modification must be signed by each party to this Agreement.

17. Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

19. Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default previously or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.

20. Further Assurances. At any time or from time to time after the date hereof, the parties agree to cooperate with each other, and at the request of any other party, to execute and deliver any further instruments or documents and to take all such further action as the other party may reasonably request in order to evidence or effectuate the consummation of the transactions contemplated hereby and to otherwise carry out the intent of the parties hereunder.

21. Specific Enforcement. The Stockholder acknowledges and agrees that irreparable harm will result in the event any of the provisions of this Agreement are not performed by the Stockholder in accordance with their specific terms or are otherwise breached. Accordingly, it is agreed that the Company shall be entitled to an injunction to prevent breaches of this Agreement, and to specific enforcement of this Agreement and its terms and provisions in any action instituted in any court of the United States or any state having subject matter jurisdiction, as further provided in Section 23.

22. Entire Agreement. This Agreement constitutes the entire agreement among the parties hereto with respect to the subject matter hereof and supersedes all prior agreements, understandings and arrangements, both oral and written, among the parties hereto with respect to such subject matter.

23. Enforceability. The parties expressly agree that this Agreement shall be specifically enforceable in any court of competent jurisdiction in the United States in accordance with its terms against each of the parties hereto. If any provision of this Agreement shall be declared void or unenforceable by any court or administrative board of competent jurisdiction, such provision shall be deemed to have been severed from the remainder of this Agreement and this Agreement shall continue in all respects to be valid and enforceable and shall be construed so as to best give effect to the intention of the voided or unenforceable term or provision.

Exhibit 10.4

SETTLEMENT AGREEMENT AND GENERAL AND MUTUAL RELEASE

This Settlement Agreement and General and Mutual Release (the “Agreement”) is entered into as of the date set forth in the signature block of this Agreement by and between KALA BIO Inc. (the “Company”) and _____________, the __________ of the Company (“Officer”), collectively known herein as the “Parties.”

WHEREAS, Officer was and appointed as _____________ of the Company to provide the services commensurate with such position(s) in other public companies of similar sizes and industries (the “Services”).

WHEREAS, Officer has provided the Services above and beyond such as commonly performed by an officer of a company in a similar position.

WHEREAS, there is no dispute as to the provision of the Services nor any disagreements with the Company.

WHEREAS, the Parties desire and intend that this Agreement supplement and modify all prior contracts, agreements and understandings between the Parties related to Officer’s terms of employment with and separation from the Company, including Officer’s eligibility to receive severance benefits.

NOW, THEREFORE, the Parties, intending to be legally bound, and in consideration of the mutual promises, covenants and agreements contained herein and other good and valuable consideration, the sufficiency of which is hereby acknowledged, agree as follows:

1. Settlement Payment Due to Officer from the Company.

Upon Shareholder Meeting, the Company shall pay to Officer a cash settlement payment of $_______ (the “Settlement Payment”), less all applicable taxes and withholdings. The Settlement Payment is equal to five percent (5%) of Officer’s current contractual severance pay eligibility of $_________ (the “Prior Severance”), and shall be in lieu of Officer’s eligibility to receive the Prior Severance. Officer acknowledges and agrees that following execution hereof, Officer will not be eligible for, nor shall Officer have a right to receive Prior Severance or any payments or benefits from the Company other than the Settlement Payment [and any wages accrued through Officer’s last day of employment with the Company].

2. Resignation and Release.
