"Qualified distribution" means any payment or distribution:
provided, however, that a payment or distribution shall not be treated as a qualified distribution if it is made within the 5-taxable-year period beginning with the first taxable year for which the individual made a contribution to a Roth IRA (or such individual's spouse made a contribution to a Roth IRA) established for such individual, or in the case of a payment or distribution allocable to a qualified rollover contribution from an individual retirement plan other than a Roth IRA (or income allocable thereto), it is made within the 5-taxable year period beginning with the taxable year in which the rollover contribution was made.
