Employee Stock Purchase Plan

The Company has an employee stock purchase plan pursuant to which employees of the Company may participate to purchase shares of common stock at a discount. During the three-months ended March 31, 2020 and 2019, the Company issued 156,845 and 31,618 shares of common stock, respectively, to employees under the employee stock purchase plan for proceeds of $6,666 and $1,581, respectively. As of March 31, 2020, 318,316 shares of common stock remain available for issuance under the employee stock purchase plan.

Stock-Based Compensation Plans

2015 Incentive Plan - In April 2015, the Company’s Board of Directors approved the International Isotopes Inc. 2015 Incentive Plan (as amended, the 2015 Plan), which was subsequently approved by the Company’s shareholders in July 2015. The 2015 Plan was amended and restated in July 2018 to increase the number of shares authorized for issuance under the 2015 Plan by an additional 20,000,000 shares. The 2015 Plan provides for the grant of incentive and non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and units, and other stock or cash-based awards.  The 2015 Plan amended and restated the Company’s Amended and Restated 2006 Equity Incentive Plan (2006 Plan). The 2015 Plan authorizes the issuance of up to 80,000,000 shares of common stock, plus 11,089,967 shares authorized, but not issued under the 2006 Plan. At March 31, 2020, there were 34,135,593 shares available for issuance under the 2015 Plan.

Employee/Director Grants - The Company accounts for issuances of stock-based compensation to employees by recognizing, as compensation expense, the cost of employee services received in exchange for equity awards. The compensation expense is based on the grant date fair value of the award. Stock option compensation expense is recognized over the period during which an employee is required to provide service in exchange for the award (the vesting period).

Non-Employee Grants - The Company accounts for its issuances of stock-based compensation to non-employees by measuring the value of any awards that were vested and non-forfeitable at their date of issuance based on the grant date fair value of the award. The non-vested portion of awards that are subject to the future performance of the counterparty are adjusted at each reporting date to their fair values based upon the then current market value of the Company’s stock and other assumptions that management believes are reasonable.

Option awards outstanding as of March 31, 2020, and changes during the three-months ended March 31, 2020, were as follows:

Fixed Options	Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Life		Aggregate Intrinsic Value

The intrinsic value of outstanding and exercisable shares is based on the closing price of the Company’s common stock on the OTCQB of $0.06 per share on March 31, 2020, the last trading day of the quarter.

As of March 31, 2020, there was $59,808 of unrecognized compensation expense related to stock options that will be recognized over a weighted-average period of 1.76 years.

Total stock-based compensation expense for the three-months ended March 31, 2020 and 2019 was $51,522 and $63,737 respectively.

Pursuant to an employment agreement with its Chief Executive Officer, the Company awarded 500,000 fully vested shares of common stock to its Chief Executive Officer in February 2020 under the 2015 Plan. The number of shares awarded was based on a $28,000 stock award using a price of $0.056 per share. The employment agreement provides that the number of shares issued will be based on the average closing price of common stock for the 20 trading days prior to issue date but not less than $0.05 per share. Compensation expense recorded pursuant to this stock grant was $18,128, which was determined by multiplying the number of shares awarded by the closing price of the common stock on February 28, 2020, which was $0.06 per share. The Company withheld 197,875 shares of common stock to satisfy the employee’s payroll tax obligations in connection with this issuance. The net shares issued on February 28, 2020 totaled 302,125.
