  A Banach space X with closed unit ball B is said to have property 2-beta,
repsectively 2-NUC if for every \ep > 0, there exists \delta > 0 such that for
every \ep-separated sequence (x_n) in the unit ball B, and every x in B, there
are distinct indices m and n such that ||x + x_m + x_n|| < 3(1 - \delta),
respectively, ||x_m + x_n|| < 2(1 - \delta). It is shown that a Banach space
constructed by Schachermayer has property 2-beta but cannot be renormed to have
property 2-NUC.
