However, section 408(b)(2) does not contain an exemption from acts described in section 406(b)(1) of the Act (relating to fiduciaries dealing with the assets of plans in their own interest or for their own account), section 406(b)(2) of the Act (relating to fiduciaries in their individual or in any other capacity acting in any transaction involving the plan on behalf of a party (or representing a party) whose interests are adverse to the interests of the plan or the interests of its participants or beneficiaries) or section 406(b)(3) of the Act (relating to fiduciaries receiving consideration for their own personal account from any party dealing with a plan in connection with a transaction involving the assets of the plan). Such acts are separate transactions not described in section 408(b)(2). See § 2250.408b-2 (e) and (f) for guidance as to whether transactions relating to the furnishing of office space or services by fiduciaries to plans involve acts described in section 406(b)(1) of the Act. Section 408(b)(2) of the Act does not contain an exemption from other provisions of the Act, such as section 404, or other provisions of law which may impose requirements or restrictions relating to the transactions which are exempt under section 408(b)(2). See, for example, section 401 of the Internal Revenue Code of 1954. The provisions of section 408(b)(2) of the Act are further limited by section 408(d) of the Act (relating to transactions with owner-employees and related persons).
