Well, to start IANAL :-)

So you're getting amateur legal opinions here.

Note the clause 3e:

These requirements must be reproduced intact in any source distribution and shall apply to anyone to whom you have granted a further right to modify the source code of your derived work.

So just by changing these things you don't remove the unacceptable part of the license. They basically are requiring you to propagate these terms regardless.
