(2) This Regulation (Subpart E, §§ 41.42 through 41.49) does not apply to:

(i) Financial relations between a customer and a security futures intermediary to the extent that they comply with a portfolio margining system under rules that meet the criteria set forth in section 7(c)(2)(B) of the Exchange Act and that are effective in accordance with section 19(b)(2) of the Exchange Act and, as applicable, section 5c(c) of the Act;

(ii) Financial relations between a security futures intermediary and a foreign person involving security futures traded on or subject to the rules of a foreign board of trade;

(iv) Financial relations between a security futures intermediary and a person based on a good faith determination by the security futures intermediary that such person is an exempted person; and

(v) Financial relations between a security futures intermediary and, or arranged by a security futures intermediary for, a person relating to trading in security futures by such person for its own account, if such person:

(A) Is a member of a national securities exchange or national securities association registered pursuant to section 15A(a) of the Exchange Act; and

(B) Is registered with such exchange or such association as a security futures dealer pursuant to rules that are effective in accordance with section 19(b)(2) of the Exchange Act and, as applicable, section 5c(c) of the Act, that:

(1) Require such member to be registered as a floor trader or a floor broker with the Commission under section 4f(a)(1) of the Act, or as a dealer with the SEC under section 15(b) of the Exchange Act;

(2) Require such member to maintain records sufficient to prove compliance with this paragraph (c)(2)(v) and the rules of the exchange or association of which it is a member;

(3) Require such member to hold itself out as being willing to buy and sell security futures for its own account on a regular or continuous basis; and

(4) Provide for disciplinary action, including revocation of such member's registration as a security futures dealer, for such member's failure to comply with this Regulation (Subpart E, §§ 41.42 through 41.49) or the rules of the exchange or association.

(d) Exemption. The Commission may exempt, either unconditionally or on specified terms and conditions, financial relations involving any security futures intermediary, customer, position, or transaction, or any class of security futures intermediaries, customers, positions, or transactions, from one or more requirements of this Regulation (Subpart E, §§ 41.42 through 41.49), if the Commission determines that such exemption is necessary or appropriate in the public interest and consistent with the protection of customers. An exemption granted pursuant to this paragraph shall not operate as an exemption from any SEC rules. Any exemption that may be required from such rules must be obtained separately from the SEC.
