This is not true!...

Export ciphers also use full-length keys (for ex. 128-bits for Exp_RC4)
and the most significant 88 bits of these keys are not equal to zero.

For export ciphers, only 40 bits of the randomness source used to generate
a 128-bit key is kept secret (see The SSL Protocol Version 3.0 by Netscape
Communications Corp. - Section 8.2.2.1 Export Key Geneartion Example)
