, by its acceptance of the Notes, or any interest therein, each purchaser and holder of the Notes, or any interest therein, and each
subsequent transferee of the Notes, or any interest therein, will be deemed to have represented and warranted that either (i) such purchaser or subsequent transferee is not, and is not acting on behalf of or using the assets of, a Plan to
acquire or hold the Notes, or any interest therein, or (ii) the purchase, holding and subsequent disposition of the Notes, or any interest therein, by such purchaser or transferee does not, and will not, constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or a violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to be all-inclusive. Due to the
complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering
purchasing and/or holding of the Notes, or any interest therein, on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code or any Similar Law and whether
an exemption would be required. Neither this discussion nor anything provided in this prospectus supplement is, or is intended to be, investment advice directed at any potential Plan purchasers, or at Plan purchasers generally, and such purchasers
of the Notes, or any interest therein, should consult and rely on their own counsel and advisers as to whether an investment in the Notes, or any interest therein, is suitable for the Plan.
