(d) The issuance of an administrative exemption by the Department under these procedural rules does not relieve a fiduciary or other party in interest or disqualified person with respect to a plan from the obligation to comply with certain other provisions of ERISA, the Code, or FERSA, including any prohibited transaction provisions to which the exemption does not apply, and the general fiduciary responsibility provisions of ERISA which require, among other things, that a fiduciary discharge his or her duties respecting the plan solely in the interests of the participants and beneficiaries of the plan and in a prudent fashion; nor does it affect the requirement of
section 401(a) of the Code that the plan must operate for the exclusive benefit of the employees of the employer maintaining the plan and their beneficiaries.
