Common Stock

2018 Public Offerings

On April 6, 2018, the Company entered into a securities purchase agreement with certain investors pursuant to which the Company agreed to issue and sell, in a registered offering by the Company directly to the investors, an aggregate of 900,000 shares of the Company’s common stock, par value $0.001 per share, at an offering price of $2.00 per share. In a concurrent private placement, the Company agreed to issue to the investors who participated in the registered offering, warrants exercisable for one share of common stock for each share purchased in the registered offering for an aggregate of warrants to purchase 900,000 shares of common stock at an exercise price of $2.00 per share. Each warrant is exercisable beginning on the six-month anniversary of the date of its issuance and will expire five years from the date of issuance.

On July 17, 2018, the Company announced the closing of an underwritten public offering (the “Public Offering”) of Class A Units, priced at a public offering price of $1.00 per unit, with each unit consisting of one share of common stock and a seven-year warrant to purchase one share of common stock with an exercise price of $1.00 per share, and Class B Units, priced at a public offering price of $1.00 per unit, with each unit comprised of one share of series D preferred stock (the “Series D Preferred Stock”), which is convertible into one share of common stock, and a warrant. The conversion price of the Series D Preferred Stock issued in the transaction as well as the exercise price of the Warrants are fixed and do not contain any variable pricing features or any price based anti-dilutive features. The securities comprising the units were immediately separable and have been issued separately.

The conversion price of the Series D Preferred Stock and exercise price of the warrants is subject to appropriate adjustment in the event of recapitalization events, stock dividends, dilutive issuances, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting the Company’s common stock.

A total of 4,436,000 shares of common stock, 9,364,000 shares of Series D Preferred Stock convertible into 9,364,000 shares of common stock, and total warrants to purchase 13,800,000 shares of common stock were issued in the Public Offering inclusive of the underwriters exercise of their over-allotment option to purchase 1,800,000 shares of common stock and warrants to purchase 1,800,000 shares of common stock at the Public Offering price per share less the underwriting discounts and commissions.

The Company’s non-employee directors, Frederick Telling and Alan Dunton participated in the Public Offering through the purchase of 100,000 shares and 20,000 shares, respectively, of the Company’s common stock and warrants to purchase 100,000 shares and 20,000 shares, respectively, of the Company’s common stock.

The net proceeds to the Company from the Public Offering, after deducting Underwriter fees and expenses and the Company’s Public Offering expenses, was approximately $12.4 million. The Company anticipates using the net proceeds from this Public Offering to continue funding development of AG013, our ongoing Phase 2 clinical trial for the treatment of Oral Mucositis, our pre-clinical development of our lantibiotics program and for general corporate purposes, including research and development activities, capital expenditures and working capital.

The proceeds received in the Public Offering were allocated to each instrument on a relative fair value basis. Total proceeds of $13.8 million were allocated to warrants issued, $6.5 million, common stock, $2.3 million and Series D Preferred Stock, $5.0 million. The allocation resulted in an effective conversion price for the Series D Preferred Stock that was below the quoted market price of the Company’s common stock on the closing date. As such, the Company recognized a beneficial conversion feature equal to the intrinsic value of the conversion feature on the closing date, resulting in a deemed dividend for the Series D Preferred Stock of approximately $1.4 million recognized on the closing date.

2019 Public Offering

On March 25, 2019, the Company announced the closing of an underwritten public offering for gross proceeds of approximately $12.5 million, which included the partial exercise of the underwriter’s over-allotment option to purchase additional shares and warrants, prior to deducting underwriting discounts and commissions and offering expenses payable by the Company.

Each short-term warrant has an exercise price of $0.75 per share of common stock, is immediately exercisable, and will expire on the earlier of (1) the eighteen-month anniversary of the date of issuance and (2) twenty-one trading days following the Company’s release of top-line data related to its Phase 2 double blind, placebo controlled clinical trial of AG013.

Preferred Stock

Issuance of Series A Convertible Preferred Stock Financing

On May 10, 2017 we entered into a securities purchase agreement with three accredited investors, to purchase up to $3,000,000 of Series A Convertible Preferred Stock (the “Series A Preferred Stock Financing”). The sale of the Preferred Stock took place in two separate closings and at the first closing which occurred on May 10, 2017, we received gross proceeds of approximately $1,302,000. The second closing occurred on July 25, 2017 and we received gross proceeds of approximately $1,698,000, which was the balance of the Preferred Stock Financing. The full $3,000,000 of Preferred Stock, and after giving effect to the reverse stock split and the previous conversion of 2,583,000 shares of Series A Preferred Stock into 258,300 shares of the Company’s common stock, is convertible into nine hundred, forty one thousand, seven hundred and one shares of our common stock, based on a fixed conversion price of $2.50 per share on an as-converted basis. In addition, and after giving effect to the reverse stock split, we issued warrants to purchase an aggregate of 462,106 shares of common stock at the first closing and we issued an aggregate of 602,414 shares of common stock at the second closing. The warrants have a term of seven years from the date of issuance are non-exercisable until 6 months after issuance, have an exercise price of $3.10 per share. Proceeds from the Series A Preferred Stock Financing (including the exercise of any warrants for cash) will be used for general corporate purposes, including working capital.

On July 27, 2017, we entered into an agreement to amend the warrants issued in connection with the Series A Preferred Stock Financing to provide notification and objection requirements with respect to the change of control provisions. The change of control provisions in the warrants had previously caused the warrants to be treated as a derivative liability as opposed to being treated as equity on our balance sheet. The warrants have been replaced by amended and restated warrants containing such notification and objection requirements (the “Amended and Restated Common Stock Purchase Warrants”) so that the Amended and Restated Common Stock Purchase Warrants are now treated as equity on our balance sheet. All other terms of the original warrants remain unchanged by the Amended and Restated Common Stock Purchase Warrants.

In connection with the Series A Preferred Financing, we filed a Certificate of Designations of Preferences, Rights and Limitations of Series A Preferred Stock with the Secretary of State of the State of Florida, to be effective May 10, 2017. The number of shares of Preferred Stock designated as Series A Preferred Stock is 12,000,000.

In connection with the issuance and sale of the Series A Preferred Stock and warrants, we granted certain demand registration rights and piggyback registration rights with respect to the shares of our Common Stock issuable upon conversion of the Preferred Stock and exercise of the Warrants, pursuant to a Registration Rights Agreement.

Except as otherwise required by law, the Series A Preferred Stock shall have no voting rights. However, as long as any shares of Series A Preferred Stock are outstanding, we shall not, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series A Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series A Preferred Stock or alter or amend the Certificate of Designation, (b) amend its articles of incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series A Preferred Stock, (c) increase the number of authorized shares of Series A Preferred Stock, or (d) enter into any agreement with respect to any of the foregoing. Upon any liquidation, dissolution or winding-up by us, whether voluntary or involuntary that is not a Fundamental Transaction (as defined in the Certificate of Designation), the holders of Series A Preferred Stock shall be entitled to receive out of the assets, the greater of (i) the product of the number of shares of Series A Preferred Stock then held by such holder, multiplied by the Original Issue Price; and (ii) the amount that would be payable to such holder in the Liquidation in respect of Common Stock issuable upon conversion of such shares of Series A Preferred Stock if all outstanding shares of Series A Preferred Stock were converted into Common Stock immediately prior to the Liquidation. The Series A Preferred Stock is classified as permanent equity.

The Series B Non-Voting, Convertible Preferred Stock Financing

On November 8, 2017, we completed a private placement of $3,300,000 of Series B Non-Voting, Convertible Preferred Stock (the “Series B Convertible Preferred Stock”) pursuant to a Securities Purchase Agreement with four existing shareholders who are accredited investors including an entity affiliated with a director of the Company (the “Series B Preferred Stock Financing”).

The full $3,300,000 of Series B Convertible Preferred Stock is convertible, after giving effect to the reverse stock split into one million three hundred and twenty thousand and two shares of our Common Stock, based on a conversion of one share of Series B Preferred Stock into two shares of Common Stock. The purchase price per share of the Series B Preferred Stock is represented by $2.50 per share of the Common Stock on an as converted basis. In addition, and after giving effect to the reverse stock split, we issued to the investors in the private placement accompanying common stock purchase warrants to purchase an aggregate of 1,064,518 shares of Common Stock. The warrants have a term of seven years from the date of issuance, and are non-exercisable until six (6) months after issuance, and after giving effect to the reverse stock split, have an exercise price of $3.10 per share.

In connection with the Series B Preferred Financing, we filed a Certificate of Designation and Rights of Series B Convertible Preferred Stock with the Secretary of State of the State of Florida, to be effective November 8, 2017. The number of shares of Preferred Stock designated as Series B Preferred Stock is 6,600,000.

Except as otherwise required by law, the Series B Preferred Stock shall have no voting rights. However, as long as any shares of Series B Preferred Stock are outstanding, we shall not, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series B Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series B Preferred Stock or alter or amend the Certificate of Designation, (b) amend its articles of incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series B Preferred Stock, (c) increase the number of authorized shares of Series B Preferred Stock, or (d) enter into any agreement with respect to any of the foregoing.

The Series B Preferred Stock is classified as permanent equity.

The Series C Non-Voting, Non- Convertible Preferred Stock Financing Precigen Debt Conversion

Concurrently with the Series B Preferred Stock Financing, we also entered into a Debt Conversion Agreement (the “Precigen Debt Conversion Agreement”) with Precigen, Inc. (formerly Intrexon Corporation (“Intrexon”) pursuant to which Precigen exchanged the $2,400,000 unsecured non-convertible promissory note previously issued by us to Precigen (the “Precigen Note”), the accrued interest on the Precigen Note and trade payables owed by us (collectively the “Debt”) in the aggregate amount of approximately $3,400,000 for equity in the form of 100 shares of Series C, Non-Voting, Non-Convertible Preferred Stock (the “Series C Preferred Stock”) issued by us to Precigen pursuant to the Debt Conversion Agreement which 100 shares have a stated value equal to the amount of the Debt.

The number of shares of Preferred Stock designated as Series C Preferred Stock is 1,000.

Each issued and outstanding share of Series C Preferred Stock entitles the holder of record to receive dividends at the annual rate of twelve percent (12%) (the “Initial Rate”) of its Stated Value, payable by issuing additional shares of Series C Preferred Stock within thirty days after the end of each calendar year pro-rata for partial years. The Initial Rate shall be subject to increase to twenty percent (20%) automatically after May 10, 2019.

The Series C Preferred Stock shall rank senior to the Common Stock, Series A Preferred Stock, Series B Preferred Stock and to any other equity securities issued by us (the “Junior Securities”) as to rights upon liquidation, dissolution or winding-up by us, whether voluntary or involuntary.

Upon any liquidation, dissolution or winding-up by us, whether voluntary or involuntary, the holders of Series C Preferred Stock shall be entitled to receive, in preference to the Junior Securities, an amount of cash equal to the product of (i) sum of (a) the number of shares of Series C Preferred Stock then held by such holder plus, (b) the number of shares of Series C Preferred Stock issuable to such holder in connection with any accrued but unpaid dividends, multiplied by (ii) the Stated Value, of $33,847.9874 per share, of Series C Preferred Stock (“the Series C Liquidation Amount”) and no distribution or payments shall be made in respect of any Junior Securities unless all Series C Liquidation Amounts, if any, are first paid in full.

As a result of the recent sale by Precigen of its equity interest in Oragenics to TS Biotechnology LLC, future dividend payments would be paid to TS Biotechnology.

Series D Non-Voting, Convertible Preferred Stock Financing

On July 17, 2018, we announced the closing of an underwritten public offering (the “Public Offering”) of units for gross proceeds of approximately $13.8 million, which included the full exercise of the underwriter’s over-allotment option to purchase additional shares and warrants, prior to deducting underwriting discounts and commissions and offering expenses.

The securities comprising the units were immediately separable and were issued separately.

The conversion price of the Series D Preferred Stock and exercise price of the warrants is subject to appropriate adjustment in the event of recapitalization events, stock dividends, dilutive issuances, stock splits, stock combinations, reclassifications, reorganizations or similar events affecting the Company’s common stock.

In connection with the Public Offering, the Company filed a Certificate of Designation of Preferences, Rights and Limitations of the Series D Preferred Stock on July 13, 2018, with the Secretary of State of the State of Florida which became effective upon filing. The Certificate of Designation provides for the issuance of the shares of Series D Preferred Stock. With certain exceptions, the shares of Series D Preferred Stock rank on par with the shares of the Common Stock, in each case, as to dividend rights and distributions of assets upon liquidation, dissolution or winding up of the Company.

With certain exceptions, as described in the Certificate of Designation, the shares of Series D Preferred Stock have no voting rights. However, as long as any shares of Series D Preferred Stock remain outstanding, the Certificate of Designation provides that the Company shall not, without the affirmative vote of holders of a majority of the then outstanding shares of Series D Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Preferred Stock or alter or amend this Certificate of Designation, (b) amend its certificate of incorporation or other charter documents in any manner that adversely affects any rights of the Holders, (c) increase the number of authorized shares of Preferred Stock, or (d) enter into any agreement with respect to any of the foregoing.

The “Conversion Price” is initially $1.00, subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions as specified in the Certificate of Designation. Notwithstanding the foregoing, the Certificate of Designation further provides that the Company shall not effect any conversion of the shares of Series D Preferred Stock, with certain exceptions, to the extent that, after giving effect to an attempted conversion, the holder of shares of Series D Preferred (together with such holder’s affiliates and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of Common Stock in excess of 4.99% of the shares of Common Stock then outstanding (or, upon election by a Holder prior to the issuance of the Warrants, 9.99%). At the holder’s option, upon notice to the Company, the holder may increase or decrease this beneficial ownership limitation not to exceed 9.99% of the shares of Common Stock then outstanding, with any such increase becoming effective upon 61 days’ prior notice to the Company.

Additionally, subject to certain exceptions and limitations, at any time prior to the three year anniversary of the issuance of the Series D Preferred Stock, the Company will have the right to cause each holder of the Series D Preferred Stock to convert all or part of such holder’s Series D Preferred Stock in the event that (i) the volume weighted average price of our common stock for each of 30 consecutive trading days exceeds $3.00 (subject to adjustment for stock splits, recapitalizations, stock dividends and similar transactions), (ii) the average daily trading volume for such measurement period exceeds $175,000 per trading day and (iii) the holder is not in possession of any information that constitutes or might constitute, material non-public information which was provided by the Company.
