The stock option price of incentive stock options granted was not permitted to be less than the fair market value on the effective date of the grant. Other types of options and awards under the 2012 Plan could be granted at any price approved by the administrator. Options, restricted stock, and restricted stock units generally vest over three or four years and expire ten years after grant. The 2012 Plan expired in June 2022.

In addition, the 2013 Plan was amended to reduce the number of shares reserved for issuance under the 2013 Plan to the number of shares that were then subject to outstanding awards under the 2013 Plan, leaving no shares available for future grant. The 2013 Plan provided for granting non-statutory stock options, stock appreciation rights, restricted stock, restricted stock and performance units, and stock grants solely to newly hired employees as a material inducement to accepting employment with the Company. Options were granted at market value on the grant date under the 2013 Plan, unless determined otherwise at the time of grant by the administrator.

PSUs are issued to a group of executives with vesting that is contingent on both market performance and continued service. The PSUs generally vest over periods ranging from one to three years based on Total Shareholder Return ("TSR"), as measured relative to specified market indices during the period from grant date through vesting date. A 2x multiplier will be applied for each percentage point of positive or negative relative TSR, such that the number of shares of common stock earned will increase or decrease by 2% of the target number of shares, subject to a maximum of 200% of the target number of shares. In the event that the Company’s relative TSR performance is less than negative 30%, relative to the specified index, no shares will be earned for the applicable performance period. All PSU awards vest at the end of the respective performance periods for those executives with continued service.

The Company's Amended and Restated 1996 Employee Stock Purchase Plan (the "Employee Stock Purchase Plan") was adopted in June 1996 and became effective upon the closing of the Company's initial public offering in July 1997. In May 2006, the Company's board of directors approved a ten-year extension of the Employee Stock Purchase Plan. Stockholders approved the ten-year extension of the Employee Stock Purchase Plan at the 2006 Annual Meeting of Stockholders held September 2006. The Company's board of directors then approved the Second Amended and Restated 1996 Stock Purchase Plan in May 2017 which (i) eliminated the expiration date of the plan and (ii) approved a ten-year “evergreen provision” which would increase annually the number of shares available for issuance by up to 500,000 on the first day of each fiscal year. Stockholders approved these changes in August 2017. In May 2020, the Company’s board of directors approved the Amended and Restated 1996 Employee Stock Purchase Plan which (i) eliminated the “evergreen provision” and (ii) reserved for issuance 3,000,000 additional shares. At the 2020 Annual Meeting of Stockholders in August 2020, these changes were approved. As a result of these

amendments, the Employee Stock Purchase Plan is effective until terminated by the Company's board of directors. In May 2022, the Company's board of directors approved amendments to the Employee Stock Purchase Plan, including an amendment that reserved for issuance of an additional 3,600,000 shares, which were approved by the stockholders in July 2022 at the 2022 Annual Meeting. During fiscal 2023, 2022 and 2021, approximately 1.1 million, 0.7 million, and 0.7 million shares, respectively, were issued under the Amended and Restated Employee Stock Purchase Plan.

The Employee Stock Purchase Plan permits eligible employees to purchase common stock through payroll deductions at a price equal to 85% of the fair market value of the common stock at the beginning of each one-year offering period or the end of each six-month purchase period, whichever is lower. When the Employee Stock Purchase Plan was reinstated in fiscal 2005, the offering period was reduced from two years to one year. Commencing with the purchase period beginning in August 2020, the contribution amount may not exceed 20% of an employee's base compensation, including commissions and standard incentive cash bonuses, but not including non-standard bonuses and overtime wages. Prior to the August 2020 purchase period, the contribution amount was limited to 10% of an employee's base compensation, including commissions, but not including bonuses and overtime wages. In the event of a merger of the Company with or into another corporation or the sale of all or substantially all of the assets of the Company, the Employee Stock Purchase Plan provides that a new exercise date will be set for each purchase right under the plan which exercise date will occur before the date of the merger or asset sale.

In May 2017, the Company's board of directors authorized the Company to purchase $25.0 million of its common stock from time to time under the 2017 Repurchase Plan (the "Repurchase Plan"). The Repurchase Plan expires when the maximum purchase amount is reached, or upon the earlier revocation or termination by the Company's board of directors. The remaining amount available under the Repurchase Plan as of March 31, 2023 was approximately $7.1 million.

In December 2021, in a private placement, the Company's board of directors authorized the Company to repurchase approximately $45.0 million of its common stock from certain qualified investors in connection with the issuance of $137.5 million in additional aggregate principal amount of the 2024 Notes.

In August 2022, the Company repurchased in privately negotiated transactions with a limited number of holders 10,695,000 shares of its common stock for approximately $60 million, in connection with the Exchange Transaction and negotiation of the Term Loan, as further described in Note 7, Convertible Senior Notes, Term Loan and Capped Calls.
