| (a) | Qualified Nonelective Employer Contributions - The Employer may contribute an amount which it designates as a Qualified Nonelective Employer Contribution for any permissible purpose, as provided in Section 5.07 of the Basic Plan Document. If Option 1.07(a) or 1.08(a)(1) is checked, except as provided in Section 5.07 of the Basic Plan Document or as otherwise provided below, Qualified Nonelective Employer Contributions shall be allocated to all Participants who were eligible to participate in the Plan at any time during the Plan Year and are Non-Highly Compensated Employees (except as may be modified in the Nonelective Employer Contributions Addendum with regard to prevailing wage contributions) in the ratio which each such Participant’s “testing compensation”, as defined in Subsection 6.01(s) of the Basic Plan Document, for the Plan Year bears to the total of all such Participants’ “testing compensation” for the Plan Year.

| (1) þ | Qualified Nonelective Employer Contributions shall be allocated only among such Participants described above who are designated by the Employer as eligible to receive a Qualified Nonelective Employer Contribution for the Plan Year. The amount of the Qualified Nonelective Employer Contribution allocated to each such Participant shall be as designated by the Employer, but not in excess of the “regulatory maximum.” The “regulatory maximum” means the amount prescribed in Treasury Regulation Section 1.401(k)-2 which is 5% (10% for Qualified Nonelective Contributions made in connection with the Employer’s obligation to pay prevailing wages) of the “testing compensation” for such Participant for the Plan Year. The “regulatory maximum” shall apply separately with respect to Qualified Nonelective Contributions to be included in the “ADP” test and Qualified Nonelective Contributions to be included in the “ACP” test. (Cannot be selected if the Employer has elected prior year testing in Subsection 1.06(a)(2).)

The Employer may limit the eligible contributions taken into account under the allocation formula to contributions up to a specified percentage of Compensation or dollar amount or may provide for Matching Employer Contributions to be made in a different ratio for eligible contributions above and below a specified percentage of Compensation or dollar amount. The Matching Employer Contribution is allocated among “eligible” Participants so that each “eligible” Participant receives a rate or amount (which may be zero) that is identical to the rate or amount received by all other “eligible” Participants (or designated group of “eligible” Participants, if applicable) as determined by the Employer on or before the due date of the Employer’s tax return for the year of allocation.

Note: If the Matching Employer Contribution made in accordance with this Subsection 1.11(a)(2) matches different percentages of contributions for different groups of “eligible” Participants, the group of “eligible” Participants benefiting under each match rate must satisfy the nondiscriminatory coverage requirements of Code Section 410(b) and the group to whom the match rate is effectively available must not substantially favor HCEs. Each group of “eligible” Participants must also be clearly defined in a manner which will not violate the definite predetermined allocation formula requirement Section 1.401-l(b)(l)(ii) of Treasury Regulations. The Employer must notify the Trustee in writing of the amount of such Matching Employer Contributions being given to each such group.

Note: If the Matching Employer Contribution made in accordance with this Subsection 1.11(a)(2) is made to Participants who are receiving 401(k) Safe Harbor Nonelective Employer Contributions or 401(k) Safe Harbor Matching Contributions, in order to satisfy the safe harbor contribution requirement for the “ACP” Test, the dollar amount of the discretionary Matching Employer Contribution made on an “eligible” Participant’s behalf for the Plan Year may not exceed 4% of the “eligible” Participant’s Compensation for the Plan Year.

If the Employer selects (A) or (B) and does not elect Option 1.11(b), Additional Matching Employer Contributions, Matching Employer Contributions will automatically meet the safe harbor contribution requirements for deemed satisfaction of the “ACP” test. (Employee Contributions must still be tested.) 401(k) Safe Harbor Matching Employer Contributions will be made on behalf of all “eligible” Participants, unless (D) is selected below.

(C) ☐Enhanced Match:

______% of the first _____% of the “eligible” Participant’s Compensation contributed to the Plan,

______% of the next _____% of the “eligible” Participant’s Compensation contributed to the Plan,

______% of the next ______% of the “eligible” Participant’s Compensation contributed to the Plan.

| (D) ☐ | Allocation of Safe Harbor Matching Employer Contributions will only be made to certain “eligible” Participants in the amounts specified on the Matching Employer Contributions Addendum.

Note: To satisfy the 401(k) safe harbor contribution requirement for the “ADP” test, the percentages specified above for Matching Employer Contributions may not increase as the percentage of Compensation contributed increases, and the aggregate amount of Matching Employer Contributions at such rates must at least equal the aggregate amount of Matching Employer Contributions which would be made under the percentages described in Subsection (a)(1) of this Addendum.

Note: To satisfy the safe harbor contribution requirement for the “ACP” test, the Deferral Contributions and/or Employee Contributions matched cannot exceed 6% of an “eligible” Participant’s Compensation.

The additional Matching Employer Contribution may be limited to match only contributions up to a specified percentage of Compensation or dollar amount or may provide for the additional Matching Employer Contributions to be made in a different ratio for eligible contributions above and below a specified percentage of Compensation or dollar amount. The additional Matching Employer Contribution is allocated among “eligible” Participants so that each “eligible” Participant receives a rate or amount (which may be zero) that is identical to the rate or amount received by all other “eligible” Participants (or designated group of “eligible” Participants, if applicable) as determined by the Employer on or before the due date of the Employer’s tax return for the year of allocation.

Each group of “eligible” Participants must also be clearly defined in a manner which will not violate the definite predetermined allocation formula requirement Section 1.401-l(b)(l)(ii) of Treasury Regulations.

Superseding provisions which alter only provisions governed by Title I of ERISA and solely administered by the Department of Labor will not impact the ability of the Employer to rely upon the Pre-Approved Plan Provider’s opinion letter because they are outside the scope of such opinion letter.

If the Plan can be restructured to satisfy the nondiscriminatory benefits requirements, then the Plan will generally satisfy a design-based safe harbor pursuant to the regulations under Code Section 401(a)(4). If the Plan cannot be restructured to satisfy the nondiscriminatory benefits requirements, the Plan shall be required to satisfy the nondiscriminatory amount requirement by testing in accordance with Section 1.401(a)(4)-2(a) of the Treasury Regulations. If the Plan is required to pass cross-testing in accordance with Section 1.401(a)(4)-8 of the Treasury Regulations to satisfy the nondiscriminatory amount requirement and the Plan does not meet the exception found in Section 1.401(a)(4)-8(b)(1)(i)(B)(1) or (2), the Plan shall provide a minimum gateway contribution allocation to Participants who are not Highly Compensated Employees and who are required by Section 1.410(b)-3 of the Treasury Regulations to benefit under this allocation formula equal to at least 1/3rd of the allocation rate for the Highly

The Employer shall notify the Plan Administrator of the amount allocable to each group.

Note: The requirements of Treasury Regulations Section 1.401(k)-1(a)(6) (describing what constitutes a cash or deferred arrangement with respect to Self-Employed Individuals) applies to the allocation formula under this Option. Therefore, the allocation formula should be structured so that application of the formula does not create a cash or deferred arrangement with respect to a Self-Employed Individual (e.g., by permitting partners to directly or indirectly vary the amount of contribution made on their behalf).

| (5) ☐ | Age-Weighted Allocation Method – The Nonelective Employer Contribution is allocated among “eligible” Participants in the amount necessary so that the equivalent benefit accrual rate for each such “eligible” Participant is identical.

| (A) ☐ | Identification of Participant Groups - Each Contribution Period the Employer may make separate contributions to each Participant group identified below to be allocated among the “eligible” Participants in such group in accordance with the formula described above.

Note: The Participant groups identified below must be clearly defined in a manner that will not violate the definite predetermined allocation formula requirement of Treasury Regulation Section 1.401-1(b)(1)(ii) and cannot be subject to the discretion of the Employer. In addition, the design of the classifications cannot be such that the only Non-Highly Compensated Employees benefiting under the Plan are those with the lowest compensation and/or the shortest periods of service and who may represent the minimum number of such employees necessary to satisfy coverage under Code Section 410(b).
