(2) The intrinsic value of stock options exercised is the amount by which the market price of the stock on the date of exercise exceeded the market price of the stock on the date of grant.

Restricted Stock Units

The Company issues restricted stock units (“RSUs”) to acquire shares of Biolase common stock as approved by Biolase’s board of directors (the “Board”).

As of June 30, 2015, 37,000 shares of Biolase common stock have been reserved for RSUs that are outstanding.

Effective July 13, 2015, the Compensation Committee of the Board awarded 870,000 stock-settled restricted stock units of Biolase common stock to its President and Chief Executive Officer in connection with his employment agreement with the Company.

Warrants

The Company issues warrants to acquire shares of Biolase common stock underlying such warrants as approved by the Board.

Other Stock-Based Awards

Effective March 9, 2015, the Compensation Committee of the Board granted non-qualified stock options to purchase up to 871,710 shares of Biolase common stock to its Chief Financial Officer in connection with his employment agreement with Biolase. These options were granted at an exercise price of $1.99 per share, the closing price of Biolase common stock on the grant date. These options expire ten years from the grant date and vest in two tranches as follows: (i) as to options to purchase 523,026 shares (the “First Tranche”), options to purchase 130,757 shares vest and become exercisable on March 9, 2016, and options to purchase 10,896 shares vest and become exercisable each month following March 9, 2016 for a period of 35 consecutive months, and options to purchase 10,909 shares vest and become exercisable on March 9, 2019, and (ii) as to options to purchase 348,684 shares (the “Second Tranche”), 248,684 of such shares vest and become exercisable on March 9, 2025. In June 2015, the Compensation Committee accelerated the vesting of 100,000 of the Second Tranche options that had previously been scheduled to vest on March 9, 2025, such that such options vested and became exercisable as of June 23, 2015. The fair value of the First Tranche of $1.48 per share was estimated using the Black-Scholes option-pricing model with assumptions of 6.1 years for expected term, 88.79% volatility and 1.83% risk-free interest rate. The fair value of the Second Tranche of $1.70 per share was estimated using the Black-Scholes option-pricing model with assumptions of 10.0 years for expected term, 87.87% volatility and 2.19% risk-free interest rate.

Effective July 13, 2015, the Compensation Committee of the Board granted non-qualified stock options to purchase up to 870,000 shares of Biolase common stock to its President and Chief Executive Officer in connection with his employment agreement with Biolase. These options were granted at an exercise price of $1.65 per share, the closing price of Biolase common stock on the grant date. These options expire ten years from the grant date and vest over four years, with options to purchase 217,500 shares vesting and becoming exercisable on July 13, 2016 and options to purchase 18,125 shares vesting and becoming exercisable each month following July 13, 2016 for a period of 36 consecutive months.    

Net Loss Per Share – Basic and Diluted

Basic net loss per share is computed by dividing loss available to common stockholders by the weighted-average number of shares outstanding for the period. In computing diluted net loss per share, the weighted average number of shares of Biolase common stock outstanding is adjusted to reflect the effect of potentially dilutive securities.

Outstanding stock options and warrants to purchase 16,251,000 shares (including 9,206,000 shares underlying warrants issued in connection with the private placement completed by the Company on November 7, 2014) were not included in the computation of diluted loss per share for the three and six months ended June 30, 2015 as a result of their anti-dilutive effect. For the same 2014 period, anti-dilutive outstanding stock options and warrants to purchase 4,942,000 shares were not included in the computation of diluted loss per share.

Stock Dividend

In February 2014, the Board declared a one-half percent stock dividend payable March 28, 2014, to stockholders of record on March 14, 2014. During 2015, the Board has not declared any stock dividends. There is no assurance, with respect to the amount or frequency, that any stock dividend will be declared in the future.
