Share Exchange Agreement

On October 7, 2024, the Company entered into a Share Exchange Agreement (the “Exchange Agreement”) with Sealbond Limited, a British Virgin Islands corporation (“Sealbond”), pursuant to which the Company acquired 100% of the issued and outstanding common shares of Pharmagesic (Holdings) Inc., a Canadian corporation (“Pharmagesic”) (such transaction, the “Combination”). Prior to the Combination, Pharmagesic was a wholly-owned subsidiary of Sealbond and an indirect wholly-owned subsidiary of CK Life Sciences Int’l., (Holdings) Inc. (“CKLS”), a listed entity on the Main Board of the Hong Kong Stock Exchange.

Under the terms of the Exchange Agreement, on October 7, 2024 (the “Closing”), in exchange for all of the outstanding common shares of Pharmagesic immediately prior to the Effective Time, the Company issued to Sealbond, as sole shareholder of Pharmagesic, an aggregate of (A) 211,383 shares of the Company’s unregistered Common Stock, which shares shall represent a number of shares equal to no more than 19.99% of the outstanding shares of Common Stock as of immediately before the Effective Time and (B) 2,108.3854 shares of the Company’s unregistered Series A Non-Voting Convertible Preferred Stock, par value $0.0001 per share (“Series A Preferred Stock”) (as described below). The issuance of the shares of Common Stock and Series A Preferred Stock to Sealbond occurred on October 9, 2024. Each share of Series A Preferred Stock is convertible into 10,000 shares of Common Stock, subject to certain conditions described in the Exchange Agreement. The Combination was intended to be treated as a taxable exchange for U.S. federal income tax purposes. As of the issuance date of these financial statements, the initial accounting for the Combination is not complete.

The Board of Directors of the Company (the “Board”) approved the Exchange Agreement and the related transactions, and the consummation of the Combination was not subject to approval of Company stockholders. Pursuant to the Exchange Agreement, the Company agreed to hold a stockholders’ meeting to submit the certain matters to its stockholders for their consideration, including: (i) the approval of the conversion of shares of Series A Preferred Stock into shares of Common Stock in accordance with the rules of the Nasdaq Stock Market LLC (the “Conversion Proposal”) and (ii) the approval of a “change of control” under Nasdaq Listing Rules 5110 and 5635(b) (the “Change of Control Proposal”); and together with the Conversion Proposal, the “Meeting Proposals”). In connection with these matters, the Company agreed to file a proxy statement on Schedule 14A with the SEC at any time between the interim analysis readout of the Phase 2b study for Halneruon^® and June 30, 2026, or earlier, if mutually agreed upon by both parties.

Series A Preferred Stock

Holders of Series A Preferred Stock are entitled to receive dividends on shares of Series A Preferred Stock (on an as-if-converted-to-Common-Stock basis, without regard to the Beneficial Ownership Limitation (as defined in the Certificate of Designation), equal to and in the same form, and in the same manner, as dividends (other than dividends on shares of the Common Stock payable in the form of Common Stock) actually paid on shares of the Common Stock when, as if such dividends (other than dividends payable in the form of Common Stock) are paid on the shares of the Common Stock; provided, however, in no event shall Holders of Series A Preferred Stock be entitled to receive the “rights” distributed pursuant to the CVR Agreement, or any amounts paid under the CVR Agreement. In addition, holders of Series A Preferred Stock shall be entitled to receive, and the Company shall pay, payment-in-kind dividends on each share of Series A Preferred Stock, accruing at a rate equal to five percent (5.0%) per annum payable in shares of Series A Preferred Stock on the date that is 180 days after the date of the original issuance of such Series A Preferred Stock or such earlier date that that such holder may convert any portion of the Series A Preferred Stock to Common Stock.

Except as otherwise required by law, the Series A Preferred Stock does not have voting rights. However, as long as any shares of Series A Preferred Stock are outstanding, the Company may not, without the affirmative vote of the holders of a majority of the then-outstanding shares of the Series A Preferred Stock, (i) alter or change adversely the powers, preferences or rights given to the Series A Preferred Stock or alter or amend the Certificate of Designation, amend or repeal any provision of, or add any provision to, the Charter or Amended and Restated Bylaws of the Company, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of Preferred Stock, if such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series A Preferred Stock, regardless of whether any of the foregoing actions shall be by means of amendment to the Charter or by merger, consolidation, recapitalization, reclassification, conversion or otherwise, (ii) issue further shares of Series A Preferred Stock, or increase or decrease (other than by conversion) the number of authorized shares of Series A Preferred Stock (iii) prior to the Stockholder Approval (as defined in the Certificate of Designation) or at any time while at least 30% of the originally issued Series A Preferred Stock remains issued and outstanding, consummate either: (A) any Fundamental Transaction (as defined in the Certificate of Designation) or (B) any merger or consolidation of the Company with or into another entity or any stock sale to, or other business combination in which the stockholders of the Company immediately before such transaction do not hold at least a majority of the capital stock of the Company immediately after such transaction, or (iv) enter into any agreement with respect to any of the foregoing.

The Series A Preferred Stock shall rank on parity with the Common Stock as to distributions of assets upon liquidation, dissolution or winding-up of the Company, whether voluntarily or involuntarily.

Following stockholder approval of the Conversion Proposal, each share of Series A Preferred Stock will automatically convert into 10,000 shares of Common Stock, subject to certain limitations provided in the Certificate of Designation, including that the Company shall not affect any conversion of Series A Preferred Stock into shares of Common Stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than a specified percentage of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such conversion (the “Beneficial Ownership Limitation”);

provided, however, that the Beneficial Ownership Limitation will not apply after the stockholder approval of the Change of Control Proposal and upon the occurrence of certain other events as set forth in the Certificate of Designation. If at any time following the earliest of (a) Stockholder Approval (as defined in the Certificate of Designation), (b) the interim analysis of the Phase 2b study for Halneuron^® proves futile, (c) Dogwood is delisted from Nasdaq, (d) the interim analysis of the Phase 2b study for Halneuron^® is not completed by December 31, 2025, or (e) June 30, 2026, the Company fails to deliver to a Holder certificates representing shares of Common Stock or electronically deliver such shares, the Series A Preferred Stock is redeemable for cash at the option of the holder thereof at a price per share equal to the then-current Fair Value (as defined and described in the Certificate of Designation) of the Series A Preferred Stock for any undeliverable shares.

Form of Repurchase Agreement

The terms of the Exchange Agreement provides that Sealbond has the right to exercise an option, but not an obligation, after the Closing and upon the occurrence of certain conditional events including continued listing requirements, to acquire all of the Company’s and its direct and indirect subsidiaries’ intellectual property, rights, title, regulatory submissions, assignment of contracts, data and interests, as of the time of such acquisition, in and to tetrodotoxin and Halneuron®, in accordance with the terms and conditions of the form of Repurchase Agreement for a cash settlement value as defined in the agreement.

Contingent Value Rights Agreement

Concurrently with the Closing of the Combination, the Company entered into a contingent value rights agreement (the “CVR Agreement”) with a rights agent (the “Rights Agent”), pursuant to which each holder of Common Stock as of October 17, 2024, including those holders receiving shares of Common Stock in connection with the Combination, was entitled to one contractual contingent value right (each, a “CVR”) issued by the Company, subject to and in accordance with the terms and conditions of the CVR Agreement, for each share of Common Stock held by such holder as of 5:00 p.m. Eastern Daylight Time on October 17, 2024. The CVR Agreement has a term of seven years.

Each contingent value right entitles the holders (the “Holders”) thereof, in the aggregate, to 87.75% of any Upfront Payment (as defined in the CVR Agreement) or Milestone Payment (as defined in the CVR Agreement) received by the Company in a given calendar quarter.

The distributions in respect of the CVRs that become payable will be made on a quarterly basis and will be subject to a number of deductions, subject to certain exceptions or limitations, including but not limited to for certain taxes and certain out-of-pocket expenses incurred by the Company.

Under the CVR Agreement, the Rights Agent has, and Holders of at least 30% of the CVRs then-outstanding have, certain rights to audit and enforcement on behalf of all Holders of the CVRs. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than as permitted pursuant to the CVR Agreement. The Holders of the CVRs do not have the rights of a shareholder and do not have the ability to vote, rights to dividends, or other interests. The CVRs also establish certain restrictions of mergers and change in control activities, as defined in the agreement.  

Loan Agreement

On October 7, 2024, in connection with the Exchange Agreement, the Company entered into a Loan Agreement (the “Loan Agreement”) with Conjoint Inc., a Delaware corporation (“Lender”) and an affiliate of CKLS. Pursuant to the Loan Agreement, Lender agreed to make a loan to the Company in the aggregate principal amount of $19,500,000, of which (i) $16,500,000 was disbursed on October 7, 2024 and (ii) $3,000,000 will be disbursed on February 18, 2025, subject in each case to certain conditions described in the Loan Agreement. Pursuant to the terms of the Loan Agreement, the proceeds are to be used for the purpose of (1) funding operations and (2) performing clinical and research & development activities related to Halneuron^®. The Loan Agreement bears interest at the Secured Overnight Financing Rate (“SOFR”) plus

2.00%, that increases by 1.00% in the event of default that resets on an annual basis on October 1^st. The Loan Agreement is payable in full with principal and accrued interest on October 7, 2027.  

Registration Rights Agreement

On October 7, 2024, in connection with the Exchange Agreement, the Company and Sealbond entered into a Registration Rights Agreement (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, if, at any time after April 30, 2025, the Company receives a request from holders of at least forty percent (40%) of the Registrable Securities (as defined in the Registration Rights Agreement) then outstanding that the Company file a Form S-1 registration statement with respect to at least forty percent (40%) of the Registrable Securities then outstanding; provided, that, if at the time of such request, the only holder of Registrable Securities is Sealbond, there shall be no threshold percent to make such request and such threshold percent that must be covered by such request shall be thirty percent (30%) (or, in each case, a lesser percent if the anticipated aggregate offering price, net of Selling Expenses (as defined in the Registration Rights Agreement), would exceed $10,000,000), then the Company shall  as soon as practicable, and in any event within sixty (60) days after the date of such request, file a Form S-1 registration statement with the SEC.

If, at any time after April 30, 2025, the Company receives a request from holders of at least thirty percent (30%) of the Registrable Securities then outstanding that the Company file a Form S-3 registration statement with respect to outstanding Registrable Securities of such holders having an anticipated aggregate offering price, net of Selling Expenses, of at least $7,500,000; provided, that, if at the time of such request, the only holder of Registrable Securities is Sealbond, there shall be no threshold percent to make such request and the anticipated aggregate offering price, net of Selling Expenses, must be at least $1,000,000, then the Company shall as soon as practicable, and in any event within thirty (30) days after the date of such request, file a Form S-3 registration statement with the SEC.

Name Change

On October 7, 2024, the Company filed the Charter Amendment pursuant to which, effective October 9, 2024, the Company (i) effectuated the Name Change and (ii) effectuated the Reverse Stock Split described below. Pursuant to the Delaware General Corporation Law, a stockholder vote was not necessary to effectuate the Name Change and it does not affect the rights of the Company’s stockholders.

In addition, effective at the open of market trading on October 9, 2024, the Company’s Common Stock ceased trading under the ticker symbol “VIRI” and began trading on the Nasdaq Stock Market under the ticker symbol “DWTX”.

Support Agreements

In connection with the execution of the Exchange Agreement, the Company entered into stockholder support agreements (the “Company Stockholder Support Agreements”) with certain of the Company’s directors and executive officers (solely in their capacity as stockholders of the Company). Pursuant to the Company Stockholder Support Agreements, among other things, each of the Company stockholder parties thereto has agreed to vote or cause to be voted all of the shares of Common Stock owned by such stockholder in favor of the Meeting Proposals including the Conversion Proposal and the Change of Control Proposal discussed above.

Reverse Stock Split

On October 7, 2024, the Company filed the Charter Amendment to effect the Reverse Stock Split, resulting in outstanding shares of Common Stock of 1,110,317 prior to the issuance of shares pursuant to the Exchange Agreement. The Reverse Stock Split was effective in accordance with the terms of the Charter Amendment at Reverse Split Effective Time, prior to the issuance of shares of Common Stock pursuant to the Exchange

Agreement. At the Reverse Split Effective Time, every 25 shares of the Company’s issued and outstanding Common Stock converted automatically into one issued and outstanding share of Common Stock.

The Reverse Stock Split affected all stockholders uniformly and did not by itself alter any stockholder’s percentage interest in the Company’s equity, except to the extent that the Reverse Stock Split would result in a stockholder owning a fractional share. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to receive a fractional share received a cash payment equal to the fair market value of such fractional share as of the Reverse Split Effective Time, as determined in good faith by the Board.

As described in Note 2, all share and per share amounts in the financial statements and footnotes have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split.

Transaction Costs

​In connection with the Combination, the Company incurred transaction costs, not including financial advisory fees, of approximately $1,033,000 during the three and nine months ended September 30, 2024 that are included as general and administrative expenses in the statement of operations for the three and nine months ended September 30, 2024.

Tungsten Advisors (through its Broker-Dealer, Finalis Securities LLC) (“Tungsten”) acted as the financial advisor to the Company in connection with the Combination. As partial compensation for services rendered by Tungsten, the Company issued to Tungsten and its affiliates and designees an aggregate of 10,568 shares of Common Stock and 105.4190 shares of Series A Preferred Stock and paid $1,155,000 of cash in October 2024. All of the compensation to Tungsten was contingent on the closing of the Combination.

​Additional general and administrative costs will continue to be incurred as Dogwood seeks to satisfy the obligations under the Exchange Agreement, Loan Agreement and related agreements.

Stock Options Modifications

In connection with the Combination, the Company changed its composition of the Board resulting in the resignation of one of its directors. In connection with this change, the Company agreed to accelerate the vesting of 116 stock options and extend the exercise period of all of the outstanding options issued under the Company’s Plan of 851 stock options to the one year anniversary date of the director’s resignation.

Amended and Restated Incentive Plan

In connection with the Combination, the Company’s Board approved a Second Amended and Restated 2020 Equity Incentive Plan that authorizes 2,278,233 shares, after adjusting for the effects of the Reverse Stock Split, and sets annual limits of 20,000 shares for individuals and 8,000 shares for non-employee directors. The plan terminates on the tenth anniversary of its effective date. The effectiveness of the Second Amended and Restated 2020 Equity Incentive Plan remains subject to stockholder approval. Dogwood does not anticipate putting the Second Amended and Restated 2020 Equity Incentive Plan up for stockholder approval by vote at this time.
