(B) Allowance for certain health plan expenses (i) In general Such term shall include amounts paid by the eligible employer to provide and maintain a group health plan (as defined in section 5000(b)(1)), but only to the extent that such amounts are excluded from the gross income of employees by reason of section 106(a).
