NOTE I - Stock Holders Equity

Preferred Stock

In accordance with the Certificate of Incorporation, there are 10,000,000 authorized preferred shares at a par value of $ 0.001. In connection with the 2016 Private Placement, on July 26, 2016, the Company filed a Certificate of Designation (the “Certificate of Designations”) with the Secretary of State of the State of Delaware to designate the preferences, rights and limitations of the Series A Preferred Shares. Pursuant to the Certificate of Designations, the Company designated 1,600,000 shares of the Company’s previously undesignated preferred stock as Series A Preferred Stock.

Conversion:

Each Series A Preferred Share is convertible at the option of the holder into such number of shares of the Company’s common stock equal to the number of Series A Preferred Shares to be converted, multiplied by the stated value of $5.00 (the “Stated Value”), divided by the Conversion Price in effect at the time of the conversion (the initial conversion price will be $0.50, subject to adjustment in the event of stock splits, stock dividends, and fundamental transactions). Based on the current conversion price, the Series A Preferred Stock is convertible into 16,000,000 shares of common stock. A fundamental transaction means: (i) our merger or consolidation with or into another entity, (ii) any sale of all or substantially all of our assets in one transaction or a series of related transactions, or (iii) any reclassification of our Common Stock or any compulsory share exchange by which Common Stock is effectively converted into or exchanged for other securities, cash or property. Each Series A Preferred Share will automatically convert into common stock upon the earlier of (i) notice by the Company to the holders that the Company has elected to convert all outstanding Series A Preferred Shares; provided however that in the event the Company elects to force automatic conversion pursuant to this clause (i), the conversion date for purposes of calculating the accrued Dividend (as defined below) is deemed to be the July 29, 2019, which is third anniversary of the Initial Closing, (ii) three years from the Initial Closing, (iii) the approval of the Company’s MAT2203 product candidate by the U.S. Food and Drug Administration or the European Medicines Agency (the “Regulatory Approval”) or (iv) the Regulatory Approval of the Company’s MAT2501 product candidate.

Beneficial Conversion Feature- Series A Preferred Stock (deemed dividend):

Each share of Series A Preferred Stock is convertible into shares of common stock, at any time at the option of the holder at a conversion price of $0.50 per share. On July 29, 2016, August 16, 2016, and September 12, 2016, the date of issuances of the Series A, the publicly traded common stock prices were $0.67, $0.70, and $1.00 per share, respectively.

Based on the guidance in ASC 470-20-20, the Company determined that a beneficial conversion feature exists, as the effective conversion price for the Series A preferred shares at issuance was less than the fair value of the common stock into which the preferred shares are convertible. A beneficial conversion feature based on the intrinsic value of the date of issuances for the Series A was approximately $4.4 million. The beneficial conversion amount of approximately $4.4 million was then accreted back to the preferred stock as a deemed dividend and charged to accumulated deficit as the conversion rights were 100% effective at the time of issuance.

Liquidity Value and Dividends:

Pursuant to the Certificate of Designations, the Series A Preferred Shares accrue dividends at a rate of 8.0% once per year on the anniversary date of the Initial Closing, payable to the holders of such Series A Preferred Shares in shares of common stock upon conversion. Dividends of approximately $601 thousand have been accrued as paid-in-kind through December 31, 2017 and approximately $7 thousand has been earned and converted into common stock at the election of the holder. The Series A Preferred Shares vote on an as converted basis with the Company’s common stock. Upon any dissolution, liquidation or winding up, whether voluntary or involuntary, holders of Series A Preferred Shares are entitled to (i) first receive distributions out of our assets in an amount per share equal to the Stated Value plus all accrued and unpaid dividends, whether capital or surplus before any distributions shall be made on any shares of common stock and (ii) second, on an as-converted basis alongside the common stock.

Royalty:

The Series A Preferred Shares include the right, as a group, to receive: (i) 4.5% of the net sales of MAT2203 and MAT2501, in each case from and after the date, respectively, such candidate has received FDA or EMA approval, and (ii) 7.5% of the proceeds, if any, received by the Company in connection with the licensing or other disposition by the Company of MAT2203 and/or MAT2501 (“Royalty Payment Rights”). The royalty is payable so long as the Company has valid patents covering MAT2203 and MAT2501, as applicable. The Royalty Payment Rights are unsecured obligations of the Company. The royalty payment will be allocated to the holders based on their pro rata ownership of vested Series A Preferred Shares. The royalty rights that are part of the Series A Preferred Shares will vest, in equal thirds, upon each of the July 29, 2017, July 29, 2018, and July 29, 2019, which are the first, second and third anniversary dates of the Initial Closing, (each a “Vesting Date”); provided however, if the Series A Preferred Shares automatically convert into common stock prior to the 36 month anniversary of the initial closing, then the royalty rights that are part of the outstanding Series A Preferred Shares shall be deemed to be fully vested as of the date of conversion. Even if the Series A Preferred Shares are purchased after the initial closing, the vesting periods for the royalty rights that are part of the Series A Preferred Shares shall still be based on the Vesting Dates. During the first 36 months following the initial closing, the right to receive a royalty will follow the Series A Preferred Shares; after July 29, 2019 the royalty payment rights may be transferred separately from the Series A Preferred Stock subject to available exemption from registration under applicable securities laws. The Company believes that such rights are not separable free standing instruments requiring bifurcation at the date of transaction. The Company may recognize a deemed dividend for the estimated fair value of the vested portion of the royalty rights in future periods. As of December 31, 2017, no accrual has been recorded for royalty payments as it is not probable at this time that any amount will be paid.

Classification:

These Series A Preferred Shares are classified within permanent equity on the Company’s consolidated balance sheet as they do not meet the criteria that would require presentation outside of permanent equity under ASC 480 Distinguishing Liabilities from Equity.

Warrants

As of December 31, 2017, the Company had outstanding warrants to purchase an aggregate of 5,957,831 shares of common stock at exercise prices ranging from $0.50 to $2.00 per share.

The Warrants are exercisable immediately upon issuance and have a five-year term. The Warrants may be exercised at any time in whole or in part upon payment of the applicable exercise price until expiration of the Warrants. No fractional shares will be issued upon the exercise of the Warrants. The exercise price and the number of warrant shares purchasable upon the exercise of the Investor Warrants (as opposed to Placement Agent Warrants) are subject to adjustment upon the occurrence of certain events, which include stock dividends, stock splits, combinations and reclassifications of the Company capital stock or similar “organic changes” to the equity structure of the Company (see Warrant table below). Accordingly, pursuant to ASC 815, the warrants are classified as equity.

The Company may call the Warrants, other than the Placement Agent Warrants, at any time the common stock trades above $5.00 (for 13 million warrants issued in 2013) or above $ 3.00 (for 20 million warrants issued in 2015) for twenty (20) consecutive days following the effectiveness of the registration statement covering the resale of the shares of common stock underlying the Warrants, provided that the Warrants can only be called if such registration statement is current and remains effective at the time of the call and provided further that the Company can only call the Investor Warrants for redemption, if it also calls all other Warrants for redemption on the terms described above. The Placement Agent Warrants do not have a redemption feature. The Placement Agent Warrants may be exercised on a “cashless” basis. Such term is a contingent feature and within the control of the Company, therefore does not require liability classification

A summary of equity warrants outstanding (in thousands) as of December 31, 2017 is presented below, all of which are fully vested.
