(4) Special 3-year rule 
If an obligation which has been determined to be corporate acquisition indebtedness for any taxable year would not be such indebtedness for each of any 3 consecutive taxable years thereafter if subsection (b)(4) were applied as of the close of each of such 3 years, then such obligation shall not be corporate acquisition indebtedness for all taxable years after such 3 consecutive taxable years.
(5) 5 percent stock rule 
In the case of obligations issued to provide consideration for the acquisition of stock in another corporation, such obligations shall be corporate acquisition indebtedness for a taxable year only if at some time after October 9, 1969, and before the close of such year the issuing corporation owns 5 percent or more of the total combined voting power of all classes of stock entitled to vote of such other corporation.

(h) Changes in obligation 
For purposes of this section
(1) Any extension, renewal, or refinancing of an obligation evidencing a preexisting indebtedness shall not be deemed to be the issuance of a new obligation.

(i) Certain obligations issued after October 9, 1969 
For purposes of this section, an obligation shall not be corporate acquisition indebtedness if issued after October 9, 1969, to provide consideration for the acquisition of
(1) stock or assets pursuant to a binding written contract which was in effect on October 9, 1969, and at all times thereafter before such acquisition, or
(2) stock in any corporation where the issuing corporation, on October 9, 1969, and at all times thereafter before such acquisition, owned at least 50 percent of the total combined voting power of all classes of stock entitled to vote of the acquired corporation.
