(9) such trustee owns, on May fifteenth in any calendar year, in the capacity of executor, administrator, testamentary or inter vivos trustee, guardian, committee or conservator, or in any other similar capacity, an aggregate of twenty-five per centum or more of the voting securities, or of any class of security, of any person, the beneficial ownership of a specified percentage of which would have constituted a conflicting interest under subparagraph (6), (7) or (8) of this paragraph. The indenture may provide, as to any such securities of which the trustee acquired ownership through becoming executor, administrator or testamentary trustee of an estate which included them, that the provisions of the preceding sentence shall not apply, for a period of not more than two years from the date of such acquisition, to the extent that such securities included in such estate do not exceed twenty-five per centum of such voting securities or twenty-five per centum of any such class of security.

(c) The indenture shall provide that the specification of percentages in subparagraphs (5) to (9), inclusive, of paragraph (b) shall not be construed as indicating that the ownership of such percentages of the securities of a person is or is not necessary or sufficient to constitute direct or indirect control for the purposes of subparagraph (3) or (7) of paragraph (b).
(d) For the purposes of subparagraphs (6), (7), (8) and (9) of paragraph (b), (A) the terms "security" and "securities" shall include only such securities as are generally known as corporate securities, but shall not include any note or other evidence of indebtedness issued to evidence an obligation to repay moneys lent to a person by one or more banks, trust companies, or banking firms, or any certificate of interest or participation in any such note or evidence of indebtedness; (B) an obligation shall be deemed to be in default when a default in payment of principal shall have continued for thirty days or more, and shall not have been cured; and (C) the trustee shall not be deemed the owner or holder of (i) any security which it holds as collateral security (as trustee or otherwise) for an obligation which is not in default as above defined, or (ii) any security which it holds as collateral security under the indenture, irrespective of any default thereunder, or (iii) any security which it holds as agent for collection, or as custodian, escrow agent, or depositary, or in any similar representative capacity.
