BB&N 403(b) Special Schedule 2022

1 Schedule Buckingham Browne & Nichols School DC Retirement Plan This Schedule contains terms which supplement provisions in the Adoption Agreement and is effective as June 1, 2022 (the “Effective Date”) except where otherwise stated. It is an integral part of the Plan document. References (#) are to Sections in the Adoption Agreement (“AA”). #7(m). Excluded Employees. Elective Deferrals The Plan will no longer exclude employees who “normally work less than 20 hours per week” from making Elective Deferrals. All employees, regardless of work schedule or job class, may make Elective Deferrals. This provision goes into effect for the first payroll period ending in June, 2022. Employer Contributions (all types) The Plan will no longer exclude employees who “normally work less than 20 hours per week” from Employer Contributions. Employees in job categories with this expectation of limited hours are Limited Participation Employees who may be allocated Employer contributions, but only for Plan Years in which they qualify for Allocation Conditions. (See #14(i) for dfn. of Limited Participation Employees, and #28(b) for Allocation Conditions.) #10(j) Excluded Compensation For all purposes the Plan provides that compensation in excess of base salary or basic earnings is excluded, meaning bonuses, pay for overtime hours, and non-cash taxable items (such as for group insurance, if taxable). Stipends are also excluded, except that they are included for employees whose compensation consists solely or mostly in stipends. #14(i) Eligibility Rules for Full and Limited Participation Employer Contributions (all types) - Full Participation Employees An Employee is a Full Participation Employees for any Plan Year in which the Employee is not a Limited Participation Employee. - Limited Participation Employees are: - Seasonal Coaches (regardless of scheduled hours) - Summer Counsellors (regardless of scheduled hours) - Substitute Teachers paid on a per diem basis (regardless of scheduled hours) 386792

2 - Any other Temporary or Seasonal employee, if scheduled to work at a rate that would regularly be less than 20 hours per week with an expectation of less than 1,000 Hours of Service in an Eligibility Computation Period. #28(b) Allocation Conditions Full Participation Employees are eligible for Employer Contributions (Matching and Nonelective) with respect to Participating Compensation for periods when employed, regardless of hours worked. Limited Participation Employees are also eligible for Employer Contributions with respect to Participating Compensation, but only for Plan Years in which the Limited Participation Employee: - has completed one Year of Eligibility Service on or before January 1 or July 1 of the Plan Year (a one-time requirement), and - is credited with at least 1,000 hours in the Plan Year, and - is employed on December 31 of the Plan Year. If transferred from Limited Participation Status to Full Participation Status or vice versa, the above requirements will continue to apply, but only with respect to Compensation paid while in Limited Participation Status. #22(g), and #25(b)(6) Timing of Matching and Non-Elective Contributions Contributions for Full Participation Employees would typically be made at the time of, or reasonably following, the conclusion of each pay period. Contributions are on a payroll period basis (no “true-up). Contributions for Limited Participation Employees would be made after a Plan Year concludes, and generally within 2 & ½ months. Contributions are based on the Plan Year basis (called “true-up” in the AA). Employer Contributions will in no event be later than the time permitted by the Code. #14. Eligibility: New minimum age requirement for Employer Contributions A minimum age requirement is added for all Employees hired on or after the Effective Date, but only with respect to Employer Matching and Non-Elective Contributions: AGE 21. #15. Year of Eligibility Service (for Limited Participation Employees) A Year of Eligibility Service is as described in #15 of the Adoption Agreement. It is an Eligibility Computation Period in which 1,000 Hours of Service is credited. Eligibility Computation Periods are the 12 months following the first Hour of Service and Plan Years starting after the first Hour of Service. 386792

3 #16. Entry Date Entry Dates are immediate for Elective Deferrals. For Employer Contributions, they are January 1 and July 1, subject to the following: Entry Dates for Employer Contributions are immediate for Full Participation Employees, except that the Entry Date for those first hired after the Effective Date who are less than age 21, the Entry Date is the first January 1 or July 1 following age 21. Entry Dates for Limited Participation Employees are the first January 1 or July 1 following the later of one Year of Eligibility Service or, if later and if the minimum age requirement applies, age 21. 26 (g). Nonelective Contribution Allocation This Alternate allocation method, rather than pro-rata according to Compensation, will apply to some or all of a Year’s Supplemental Contributions if so designated by the Employer: A Supplemental Non-Elective Employer Contribution will be allocated after the conclusion of a Plan Year. Full Participants who are employed on September 30 (and Limited Participants who qualify for a contribution in the Plan Year due to 1,000 Hours of Service and employment on December 31) are eligible. The allocation will be on a per capita basis, so that the same amount is allocated to each eligible Participant. The Employer has full discretion whether to make a Supplemental Contribution. It also reserves the right to amend this provision to change the allocation method or the eligibility requirements, subject to Code qualification rules and ERISA. 36 (d) Vesting Schedule For any Employee whose first Hour of Service is on or after the Effective Date, a vesting schedule applies to the Accounts for Employer Matching and Nonelective Contributions. These Accounts will be forfeited if a one-Year Break in Service occurs prior to 15 months of employment, as determined under the Elapsed Time rules of the Plan. Forfeited amounts will be used to reduce Employer Contributions according to the timing rules of Section 5.07. Employees who return to Service at any time will have forfeited amounts restored and previous vesting service credited if required under Section 5.06 and the Rule of Parity. In witness whereof, this Schedule is executed and approved on this _ day of May, 2022.
