How Can You Close Down An Exe Launched With ShellExecute?

I launch an external program in the Form Create section of my app with:

ShellExecute(0, 'Open', PChar('Other.exe'), PChar(''), PChar(''), SW_Hide);

This works perfectly, but I just found out that there were approximately 30 instances of this program running when I looked in the task manager!  Obviously, each time I run my app, another copy of the external program is run. :)

Is there any way of closing down a program launched in this way when I close my app down?
