Item 9B. Other Information

On February 15, 2022, we entered into a letter agreement with Mr. Smith, our Corporate Executive Vice President and Chief Financial Officer, that amends our existing Service Agreement with him and that establishes parameters regarding a gradual and well-planned transition of his responsibilities. The letter agreement sets forth that in the event that Charles River appoints a successor to Mr. Smith’s role prior to September 30, 2022, Mr. Smith’s job title will change to Senior Financial Advisor though February 28, 2023, as he transitions his responsibilities to his successor. Throughout this transition period, Mr. Smith will remain available to answer questions related to his role and to consult with his successor or our CEO about matters where Mr. Smith’s skill, expertise or insight is considered necessary. Mr. Smith’s base compensation effective as of April 1, 2022 and through September 30, 2022 will be £479,981 per year. Mr. Smith will be eligible to receive a bonus of up to 70% of his base annual salary for the 2022 fiscal year, such bonus to be reduced on a pro-rata basis to reflect time worked within the fiscal year up to and including September 30, 2022. In lieu of a traditional annual equity grant made in May, Mr. Smith will receive a grant of restricted stock units on February 28, 2022 with a value of $1.5 million with a 12-month vesting period, such grant to be conditional upon Mr. Smith providing a smooth, structured handover of his responsibilities to his successor. The vesting of any previously granted equity awards will be unaffected and continue through February 28, 2023, with any equity that remains unvested at that date to be forfeited. The terms and conditions of any previously granted stock award agreements will be unaffected through February 28, 2023. The letter agreement provides that, notwithstanding termination of his employment, Charles River will continue to procure accountant services to Mr. Smith to complete his US and UK annual tax returns until the 2025-2026 tax year. In the event that a successor CFO is not appointed prior to September 30, 2022, Mr. Smith’s employment will continue as normal, and the terms of the letter agreement will no longer apply. In consideration for the benefits provided under the letter agreement, Mr. Smith has agreed he is not entitled to other severance or compensation benefits.
