random number generator help - Electronic Circuits Projects Diagrams Free

i have successfully build this "random number generator" http://www.ljgroup.com/techsupport/c.../1403_ds11.pdf
it uses a 555 timer a 4029 ad 4511 ic. I want to add switch so instead of it choosing a number between 0 and 9 i can flick the switch and it will only pick a number between
0 and 4. The 4029 ic simply counts from 0 - 9 , so i basically want it reset when it hits 5. if it was a 4017 ic i would simply link output 5 to the reset leg. how can i do this with the 4029 ic ???.
