The amendments made by sections 521 through 523 of this
title shall apply only with respect to loans made in any State during
the period beginning on April 1, 1980, and ending on the date, on
or after April 1, 1980, on which such State adopts a law or certifies
that the voters of such State have voted in favor of any provision, constitutional or
otherwise, which states explicitly and by its terms that such State
does not want the amendments made by such sections to apply with respect
to loans made in such State, except that such amendments shall apply
to a loan made on or after the date such law is adopted or such certification
is made if such loan is made pursuant to a commitment to make such
loan which was entered into on or after April 1, 1980, and prior to
the date on which such law is adopted or such certification is made.
