Dear Razvan,

Blue Bird is pleased to confirm our offer of employment as outlined in this Letter Agreement.

Upon Board approval, you will be appointed Chief Financial Officer, effective October 1, 2021. You will report to the Chief Executive Officer. As you know, we have announced that Phil Horlock, our current CEO, will step down from that role on October 31. Matt Stevenson, who joined Blue Bird as President on July 1, will succeed Phil as CEO on November 1.

Your annual salary will be $450,000, payable on the 10th and 25th of each month.

You will be eligible to participate in the annual Blue Bird Management Incentive Bonus Plan (“MIP”) with a target of 75% of your base salary. Funding of the MIP is based on achievement of financial metrics approved by the Compensation Committee. The Compensation Committee has discretion to substantially increase the payout of the MIP bonus if the Company’s performance exceeds the target financial metrics.

You will be eligible to participate in Blue Bird’s annual Long-Term Incentive Equity Plan (“LTI”) with a target of 75% of your base salary. Since becoming a public company in 2015, the LTI Awards have included a mix of stock options and restricted stock units (“RSUs”). For FY2021, LTI Awards for C-Level officers reporting to the CEO included 25% stock options and 75% RSUs. The LTI Awards vest annually in equal tranches over three years and are subject to performance vesting requirements established by the Board. Details regarding FY2022 LTI Awards will be reviewed in October when the Board establishes the key financial objectives for FY2022.

On or before January 15, 2022, the Company will make a one-time incentive payment to you of $100,000 to partially offset incentive payments that you will forfeit upon resigning from your current position. You agree to reimburse the Company the full amount of this incentive payment if you resign on or before September 30, 2023 without the Company’s approval.

If you are terminated without cause, you will be eligible to receive up to 12 months of base salary and continued group health insurance. This severance benefit is subject to the terms of our standard severance agreement, a copy of which has been provided to you.
