The Company is authorized to issue 10,000,000 shares of preferred stock, 40,000 of which have been designated as Series A Participating Preferred Stock, par value $0.001 per share, and 5,000,000 of which have been designated as Series B Non-Voting Convertible Preferred Stock, par value $0.001 per share (the “Series B Preferred Stock”). No shares of the Company’s Series A Participating Preferred Stock were outstanding as of June 30, 2019 and December 31, 2018. During 2017, the Company’s board of directors (the “Board”) authorized the issuance of up to 5,000,000 shares of the Series B Preferred Stock, 5,000,000 of which were outstanding as of June 30, 2019 and December 31, 2018.

The Board may from time to time, without further action by the Company’s stockholders, direct the issuance of shares of preferred stock in other series and may, at the time of issuance, determine the rights, preferences and limitations of each series, including voting rights, dividend rights and redemption and liquidation preferences. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of the Company’s common stock. Holders of shares of preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of the Company before any payment is made to the holders of shares of the Company’s common stock. Upon the affirmative vote of the Board, without stockholder approval, the Company may issue shares of preferred stock with voting and conversion rights which could adversely affect the holders of shares of its common stock.

On December 20, 2017, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with each of 21 April Fund, Ltd. and 21 April Fund, LP (collectively, the “Purchasers”), pursuant to which the Company, in a private placement, agreed to issue and sell to the Purchasers an aggregate of up to 5,000,000 shares of the Series B Preferred Stock, (collectively referred to as the “Shares”). The Purchasers agreed to purchase an aggregate of 3,000,000 Shares (“Tranche 1”) at a price of $4.00 per share in cash at the initial closing of the transaction, and at the sole option of the Company, an additional 2,000,000 Shares at a price of $4.00 per share in cash at a second closing, if any (the “Private Placement”). The total purchase price payable to the Company was $20,000,000, of which $12,000,000 was paid at the initial closing. On May 30, 2018, the Company issued 2,000,000 Shares (“Tranche 2”), at a price of $4.00 per share in the second closing of the Private Placement. Gross proceeds to the Company from the second closing were approximately $8.0 million, before deducting fees and certain expenses payable by the Company. The proceeds from the issuance of the Shares are required to be used to pay off existing debt obligations of the Company and to fund future acquisitions of technology, business and other assets by the Company.

Each Share shall be convertible into the Company’s common stock (i) following the sixth (6th) anniversary of the initial closing of the Private Placement or (ii) if earlier, during the thirty (30) day period following the last trading day of any period of three (3) or more consecutive trading days that the closing market price of the Company’s common stock exceeds $10.00. Each Share is convertible at the option of the holder of shares of Series B Preferred Stock into such number of shares of the Company’s common stock determined by taking the accreted value of such Share (purchase price plus accrued but unpaid dividends) and dividing such value by the stated value of such Share ($4.00 per share, subject to adjustment for dilutive issuances, stock splits, stock dividends and the like); provided, however, that the Company shall not convert any Shares if doing so would cause the holder thereof, along with its affiliates, to beneficially own in excess of 19.9% of the outstanding common stock immediately after giving effect to the applicable conversion (the “Ownership Limitation”), unless waiver of this restriction has been effected by the holder requesting conversion of Shares.

Based on the current conversion price, the outstanding shares, including the accretion of dividends, of Series B Preferred Stock as of June 30, 2019 would be convertible into 5,337,500 shares of the Company’s common stock. However, the conversion rate will be subject to adjustment in the event of certain instances, such as if the Company issues shares of its common stock at a price less than $4.00 per common share, subject to a minimum conversion price of $3.27 per share. As of June 30, 2019, none of the contingent conditions to adjust the total common shares to convert the Shares had been met.

Each Share is entitled to a cumulative annual dividend of 5% for the first six (6) years following the issuance of such Share and 3% for each year thereafter, with the Company retaining the option to settle each year’s dividend after the tenth (10^th) year in cash. The dividends accrue and are payable in kind upon such time as the Shares convert into the Company’s common stock. In general, the Shares are not entitled to vote except in certain limited cases, including in change of control transactions where the price per share distributable to the Company’s stockholders is expected to be less than $4.00 per share. The Certificate of Designation with respect to the Series B Preferred Stock further provides that in the event of, among other things, any change of control, liquidation or dissolution of the Company, the holders of the Series B Preferred Stock will be entitled to receive, on a pari passu basis with the holders of the common stock, the same amount and form of consideration that the holders of the Company’s common stock receive (on an as-if-converted-to-common-stock basis and without regard to the Ownership Limitation).

On August 13, 2014, in connection with the Company’s entry into a consulting agreement, the Company issued a consultant a warrant to purchase up to 85,000 shares of the Company’s common stock at a per share exercise price of $10.70 (the “2014 Consultant Warrant”). One fourth of the shares under the warrant are exercisable for cash three months from the date the 2014 Consultant Warrant was issued and quarterly thereafter. The 2014 Consultant Warrant expires on August 13, 2019. In the event of an acquisition of the Company, the 2014 Consultant Warrant shall terminate and no longer be exercisable as of the closing of the acquisition. As of June 30, 2019, the 2014 Consultant Warrant had not been exercised.

On February 8, 2017, the Company entered into Loan and Security Agreements (each, a “Loan and Security Agreement”) with each of EWB and VLL7 and VLL8 as discussed in Note 9, Financial Liabilities. The Loan and Security Agreement with EWB, as amended, provides for a $16.0 million Revolving Loan Facility, and the Loan and Security Agreement with VLL7 and VLL8 provides for a term loan (the “Term Loan”) in an aggregate principal amount of $10.0 million (the “Term Loan Facility”). In connection with the Revolving Loan Facility, the Company issued to EWB a warrant (the "EWB Warrant") to purchase up to 40,000 shares of the Company's common stock at a per share exercise price of $3.64, and in connection with the Company’s Term Loan Facility, issued to each of VLL7 and VLL8 a warrant to purchase 290,000 shares of the Company's common stock at a per share exercise price of $2.00 (the “VLL7 Warrant” and the “VLL8 Warrant,” respectively). The Company calculated the fair value of the EWB Warrant, the VLL7 Warrant and the VLL8 Warrant using the Black-Scholes pricing model using the following assumptions: estimated volatility of 78.8%, risk-free interest rate of 1.94%, no dividend yield, and an expected life of five years. The fair values of the EWB Warrant, the VLL7 Warrant and the VLL8 Warrant of $125,000, $1,037,500 and $1,037,500, respectively, were classified as equity as the settlement of the warrants will be in shares and is within the control of the Company. Each of the EWB Warrant, the VLL7 Warrant and the VLL8 Warrant is immediately exercisable for cash or by net exercise and will expire five years after its issuance, or on February 8, 2022. In connection with entering into the Loan and Security Agreements with EWB and VLL7 and VLL8, warrants to purchase an aggregate of 400,000 shares of common stock issued to the Company’s previous lender were cancelled.

In connection with securing of the new credit facilities and cancelling of all the warrants previously issued to the previous lender, the Company issued a warrant to a consultant to purchase 60,000 shares of its common stock at an exercise price of $4.60 per share (the “2017 Consultant Warrant”). The Company calculated the fair value of the 2017 Consultant Warrant using the Black Scholes pricing model using the following assumptions: estimated volatility of 78.8%, risk-free interest rate of 1.22%, no dividend yield, and an expected life of two years. The fair value of the 2017 Consultant Warrant of $119,000 was classified as equity as the settlement of the warrant would be in shares and within the control of the Company. The 2017 Consultant Warrant was immediately exercisable for cash or by net exercise and had an expiration date of February 8, 2019. On January 30, 2019, the Company issued 10,449 shares of its common stock upon the cashless net exercise of the entire 2017 Consultant Warrant.
