If stock may be considered as owned by a person under subsection (e)(1) and under any other paragraph of subsection (e), it shall be considered as owned by him under subsection (e)(1).
(B)
If stock is owned (within the meaning of subsection (d)) by two or more persons, such stock shall be considered as owned by the person whose ownership of such stock results in the corporation being a component member of a controlled group. If by reason of the preceding sentence, a corporation would (but for this sentence) become a component member of two controlled groups, it shall be treated as a component member of one controlled group. The determination as to the group of which such corporation is a component member shall be made under regulations prescribed by the Secretary which are consistent with the purposes of this part.
(C)
If stock is owned by a person within the meaning of subsection (d) and such ownership results in the corporation being a component member of a controlled group, such stock shall not be treated as excluded stock under subsection (c)(2), if by reason of treating such stock as excluded stock the result is that such corporation is not a component member of a controlled group of corporations.

(B)
such stock is to be sold to an employee (or employees) of such franchised corporation pursuant to a bona fide plan designed to eliminate the stock ownership of the parent corporation or of the common owner in the franchised corporation;
(C)
such plan—
(i)
provides a reasonable selling price for such stock, and
(ii)
requires that a portion of the employee’s share of the profits of such corporation (whether received as compensation or as a dividend) be applied to the purchase of such stock (or the purchase of notes, bonds, debentures or other similar evidence of indebtedness of such franchised corporation held by such parent corporation or common owner);
(D)
such employee (or employees) owns directly more than 20 percent of the total value of shares of all classes of stock in such franchised corporation;
