Explanatory Note

This Current Report on Form 8-K/A (this “Amendment No. 1”) is being filed as an amendment to the Current Report on Form 8-K filed by BakerCorp International, Inc. (the “Company”), originally filed with the Securities and Exchange Commission on December 11, 2013 (the “Original 8-K”) to report the departure of Mr. James Leonetti, the Company’s Vice President, Chief Financial Officer and to announce the appointment of Mr. Raymond Aronoff as Chief Financial Officer and Chief Operating Officer of the Company. This Amendment No. 1 amends the Original 8-K to provide certain compensatory information in connection with such appointment that was not determined at the time of the filing of the Original 8-K.

On January 16, 2014, in connection with Mr. Raymond Aronoff’s appointment as Chief Financial Officer and Chief Operating Officer of the Company, the Compensation Committee of the Board of Directors of the Company approved a grant of stock options, pursuant to the BakerCorp International Holdings, Inc. 2011 Equity Incentive Plan (“Equity Plan”). A total of 12,000 options were granted to Mr. Aronoff, pursuant to an option agreement, consisting of the following: (i) 6,000 options with an exercise price equal to $110, (ii) 3,000 options with an exercise price equal to $200 and (iii) 3,000 options with an exercise price equal to $300. These stock options are scheduled to become vested in 5% installments on each of the first twenty quarterly anniversaries of the date of grant, provided that Mr. Aronoff continues to serve as an employee of the Company or one of its subsidiaries on each such date, and subject to accelerated vesting under certain circumstances. The stock options will become fully vested and exercisable in the event of a change in control (as defined in the Equity Plan). In addition, the portion of outstanding stock options that would have vested had Mr. Aronoff’s employment continued until one year following the effective date of certain termination or resignation events will become vested and exercisable in the event of those termination or resignation events, including a termination by reason of death, disability or retirement, a termination by the Company without cause or a resignation by Mr. Aronoff for good reason (each term is defined in the option agreement). Following a termination of employment, except as described above, unvested stock options terminate immediately and Mr. Aronoff has the following amount of time, if any, to exercise his vested stock options following his termination: (i) vested stock options immediately terminate upon Mr. Aronoff’s termination for cause or resignation without good reason; (ii) vested stock options must be exercised prior to the first anniversary of termination following termination by reason of death, disability or retirement; or (iii) vested stock options must be exercised prior to the 90th day following the date of termination upon Mr. Aronoff’s termination without cause or resignation for good reason.
