Instructions for Completing the Enrollment Form INSTRUCTIONS FOR THE EMPLOYER Before giving this enrollment form to the participant, you should enter the essential dates (Section I) for that participant. Under the terms of the plan, there are two participant dates or entry dates per year, unless otherwise specified on the participation agreement. They occur on the first day of the plan year and the first day of the seventh month of the plan year. For example, in calendar year plans the participation or entry dates are January 1 and July 1. The correct participation date is the first entry date after the participant satisfies the age and service eligibility requirements for participation in the plan. These requirements are indicated in Section III of the adoption agreement. For example, the participation date for an employee who was hired on July 17, 2022, and whose employer elected a one-year service requirement and no age requirement would be January 1, 2024 in a calendar year plan. If the above plan is a profit sharing plan with a 401(k) feature and the employer elected six months of service requirement for the 401(k) portion of the plan while keeping the one-year requirement for the profit sharing plan, this employee would enter the 401(k) plan on July 1, 2023. The employee is not eligible for the profit sharing plan until January 1, 2024. If your plan has different eligibility requirements, please contact a Retirement Plan Account Manager for further assistance with these multiple entry dates. If an employee is entering the plan under the long-term, part-time rule*, please indicate at top of form by writing “LTPT”. It is important that you provide this information as there are specific rules regarding eligibility and vesting that apply to long-term, part-time employees only. After your employee completes the enrollment form, it should be returned to you. You must certify (Section V) each employee’s enrollment form for accuracy. Retain a copy for your records and return the original forms to the Trustees at the address listed at the top of the form. This address should not be used for overnight or express mail. Please see the prospectus for overnight mailing address. Please attach a check for $25 per enrollment form, made payable to Equitable. INSTRUCTIONS FOR THE PARTICIPANT Complete all sections of the enrollment form. Please type or print clearly with a pen. If you participate in two plans, you should have received two enrollment forms. The plan number on each form should be different (001, 002, etc.). Ask your employer which number applies to which plan. The completed form should be returned to your employer. Section I – Essential Dates Your employer will enter the information in this section. Section II – Ownership Status Complete Section II only if you have ownership in the practice. Check whichever answer is appropriate for each line. An owner-employee is someone who owns more than 10% of the capital or profits interest in an unincorporated practice. A partner is someone who has ownership in an unincorporated practice, and who is not a sole-proprietor. Section III – Beneficiary Statement Check either A or B. If you wish to make a special designation, have your employer request a designation or change of beneficiary form from the Trustees. If you checked B but have not filed a designation or change of beneficiary form, or if the designation or change of beneficiary form was not properly completed, the default beneficiary provision of the Plan document will apply in the event of death.2015ENRL-ADA x03885_core 11/23

Section IV – Allocation of Contributions “Future contributions” are contributions received by us on or after the date we receive this form. Investment allocation elections will be applied only if this Form has been properly completed. If we do not have an election on file when a contribution is received, those amounts will be invested in the plan’s Qualified Default Investment Alternative (QDIA) until a change of investment allocation is requested by the participant. Please use only whole percentages and make certain that the Future Contributions column totals 100%. Decimals, fractions or dollar amounts are not acceptable. These elections will appear on your next confirmation notice and will remain in effect until changed by appropriate notice to the Trustees. Section V – Signatures Sign and date the enrollment form. Then return the completed form to your employer. Once certified by the employer, the form will be returned to the Trustees. Retain a copy for your records. Be sure to complete the investment allocation instructions in section V before returning to your employer. HOW TO MAKE CHANGES AND ACCESS ACCOUNT INFORMATION AFTER ENROLLMENT Website: adapar.equitable.com Automated Voice Response System: 800-223-5790 Change of Investment Allocation Form For website and automated voice response system transactions, changes to investment allocation for future contributions confirmed on a business day before 4 P.M.

As a result, many part-time workers, including long term part-time (LTPT) workers, never become eligible to participate in the plan. The SECURE Act changed that by mandating that employers also permit employees who have worked at least 500 hours in at least three consecutive years to participate in their 401(k) plan as well. Please note that SECURE 2.0 legislation changed the requirement to two years of service beginning with plan years after December 31, 2024. Below are additional items included with the LTPT employee legislation. No employer contributions are required to be given to these long- term part time eligible participants Plans can exclude the impacted part-time employees from coverage and nondiscrimination testing. Employees must still satisfy plan’s age requirements If a plan already permits part-time employees to participate in your retirement plan, this law change does not change currently elected plan provisions. Please see the program website for more details concerning Long-term, part-time employees. 2015ENRL-ADA x03885_core 11/23
