The Amended Charter authorizes the issuance of (i) 1,000,000,000 shares of common stock, par value $0.0001 per share (the “Common Stock”), and (ii) 20,000,000 shares of preferred stock, par value $0.0001 per share (the “Preferred Stock”).

Such shares of Series A Convertible Preferred Stock shall have all of the rights, preferences and privileges set forth in the Certificate of Designations as more fully described below.

Rank

The Series A Convertible Preferred Stock ranks senior to all shares of ECD Common Stock, and to all other classes or series of capital stock of ECD (such junior stock is referred to herein collectively as “Junior Stock”) with respect to the preferences as to dividends, distributions and payments upon the liquidation, dissolution and winding up of ECD.

Dividend Rights

From and after the first date of issuance of any initial shares of Series A Convertible Preferred Stock (the “Initial Issuance Date”) and prior to the date of the initial exercise of the Preferred Warrants (the “Initial Preferred Warrant Exercise Date”), unless a triggering event has occurred and is continuing, holders of Series A Convertible Preferred Stock shall not be entitled to dividends. From and after the Initial Preferred Warrant Exercise Date, dividends on the Series A Convertible Preferred Stock shall commence accruing and shall be computed on the basis of a 360-day year and twelve 30-day months and shall be payable in arrears for on the first trading day of each fiscal quarter (each, an “Dividend Date”). Dividends shall be payable on each Dividend Date, to each record holder of Series A Convertible Preferred Stock on the applicable Dividend Date, in shares of ECD Common Stock (“Dividend Shares”) so long as there has been no Equity Conditions Failure; provided however, that ECD may, at its option following notice to each holder, pay dividend on any Dividend Date in cash (“Cash Dividend”) or in a combination of Cash Dividend and Dividend Shares.

Liquidation Preference

In the event of a liquidation, dissolution or winding-up of ECD, whether voluntary or involuntary, the stockholders of Series A Convertible Preferred Stock shall be entitled to receive in cash out of the assets of ECD, whether from capital or from earnings available for distribution to its stockholders (the “Liquidation Funds”), before any amount shall be paid to the holders of any of shares of Junior Stock, but pari passu with any parity stock then outstanding, an amount per share of Series A Convertible Preferred Stock equal to the sum of (i) the Black Scholes Value (as defined in the Common Warrants) with respect to the outstanding portion of all Common Warrants held by such holder (without regard to any limitations on the exercise thereof) as of the date of such event and (ii) the greater of (A) 125% of the Conversion Amount (as defined below) of such Series A Convertible Preferred Stock on the date of such payment and (B) the amount per share such holder would receive if such holder converted such Series A Convertible Preferred Stock into ECD Common Stock immediately prior to the date of such payment, provided that if the Liquidation Funds are insufficient to pay the full amount due to the holders and holders of shares of parity stock, then each holder and each holder of parity stock shall receive a percentage of the Liquidation Funds equal to the full amount of Liquidation Funds payable to such holder and such holder of parity stock as a liquidation preference, in accordance with their respective certificate of designations (or equivalent), as a percentage of the full amount of Liquidation Funds payable to all holders of Series A Convertible Preferred Stock and all holders of shares of parity stock.

Conversion and Redemption Rights

At any time after the Business Combination, each stockholder shall be entitled to convert any portion of the outstanding Series A Convertible Preferred Stock held by such stockholder into validly issued, fully paid and non-assessable shares of ECD Common Stock.
