This affect the verion of Parm99 posted on the
Amber web page and the parm99.datfile (possibly)
distributed with Amber5.

Make the following substitions

536,538c536,538
< C -CT-N -C 1 0.50 180.0 -4. phi,psi,parm94
< C -CT-N -C 1 0.15 180.0 -3. phi,psi,parm94
< C -CT-N -C 1 0.53 0.0 1. phi,psi,parm94
