In October 2010, the Board approved a share option plan (the “Plan”) for grants to Company employees, consultants, directors, and other service providers.

The grant of options to Israeli employees under the Plan is subject to the terms stipulated by Section 102 of the Israeli Income Tax Ordinance (“Section 102”). The option grants are subject to the track chosen by the Company, either the “regular income” track or the “capital gains” track, as set out in Section 102. The Company registered the Plan under the capital gains track, which offers more favorable tax rates to the employees. As a result, and pursuant to the terms of Section 102, the Company is not allowed to claim as an expense for tax purposes the amounts credited to the employees in respect of options granted to them under the Plan, including amounts recorded as salary benefits in the Company’s accounts, with the exception of the work-income benefit component, if any, determined on grant date. For non-employees and for non-Israeli employees, the Plan is subject to Section 3(i) of the Israeli Income Tax Ordinance.

Employees are typically granted stock options and/or restricted stock units, or RSUs, upon commencement of employment. Also, eligible employees may receive an annual grant of options or RSUs. Non-employee members of the Board typically receive a grant of RSUs and/or stock options annually. The term of any option granted under the Plan cannot exceed 10 years. Options shall not have an exercise price less than 100% of the fair market value of the Company’s ordinary shares on the grant date, and generally vest over a period of three years. If the individual possesses more than 10% of the combined voting power of all classes of equity of the Company, the exercise price shall not be less than 110% of the fair market value of an ordinary share of stock on the date of grant.

The Company’s RSU and option grants provide for accelerated or continued vesting in certain circumstances as defined in the plans and related grant agreements, including a termination in connection with a change in control. RSUs generally vest in a 33% increment upon the first anniversary of grant, and in either equal quarterly or annual amounts for the two years following the one-year anniversary of the grant date. Options generally vest in a 33% increment upon the first anniversary of the grant date, and in either equal quarterly or annual amounts for the two years following the one-year anniversary of the grant date.

The expected volatility is based on a mix of the Company’s historical volatility, and the historical volatility of comparable companies with similar attributes to the Company, including industry, stage of life cycle, size and financial leverage. The risk-free interest rate assumption is based on observed interest rates appropriate for the expected term of the options granted. The expected term is the length of time until the expected dates of exercising the options and is estimated for employees using the simplified method due to insufficient specific historical information of employees’ exercise behavior, and for non-employees, and directors using the contractual term.

In March 2017, the Board adopted the 2017 Equity Incentive Plan (the "2017 Plan"), which was approved by the shareholders in April 2017. The 2017 Plan provides for the grant of incentive stock options to the Company's employees and for the grant of

nonstatutory stock options, stock appreciation rights, restricted stock awards, RSU awards, performance share awards, performance cash awards, and other forms of share awards to the Company's employees, directors and consultants.

The maximum number of ordinary shares that may initially be issued under the 2017 Plan is 1,400,000. In addition, the number of ordinary shares reserved for issuance under the 2017 Plan will automatically increase on January 1st of each calendar year, from January 1, 2018 through January 1, 2026, so that the number of such shares reserved for issuance will equal 12% of the total number of ordinary shares outstanding on the last day of the calendar month prior to the date of each automatic increase, or a lesser number of shares determined by the Board. The maximum number of ordinary shares that may be issued upon the exercise of stock options under the 2017 Plan is 5,600,000. On January 1, 2018, the share reserve increased by 250,167 to 1,650,167. On October 12, 2018, the Company increased the amount of registered ordinary shares of the Company’s 2017 Plan by 1,900,000 to 3,550,167. On June 8, 2020 the Company increased the amount of registered ordinary shares of the Company’s 2017 Plan by 400,000 to 3,950,167. On March 17, 2021, the Board approved an increase to the amount of registered ordinary shares of the Company’s 2017 Plan by 400,000 to 4,350,167, subject to approval by the Company’s shareholders.

In May 2019, the Company adopted the UroGen Pharma Ltd. 2019 Inducement Plan (the “Inducement Plan”). Under the Inducement Plan, the Company is authorized to issue up to 900,000 ordinary shares pursuant to awards issued under the Inducement Plan. The only persons eligible to receive grants of Awards (as defined below) under the Inducement Plan are individuals who satisfy the standards for inducement grants under Nasdaq Marketplace Rule 5635(c)(4) or 5635(c)(3) and the related guidance under Nasdaq IM 5635-1, including individuals who were not previously an employee or director of the Company or are following a bona fide period of non-employment, in each case as an inducement material to such individual’s agreement to enter into employment with the Company. Under the Inducement Plan, an “Award” is a nonstatutory stock option, restricted stock unit or other right to receive ordinary shares pursuant to the Inducement Plan.
