I am not 100% sure why I was getting syntax errors based on @juergen d's answer, but I found this and it seems to work just as well.
Dim psInfo As New System.Diagnostics.ProcessStartInfo("path_to_exe", Arg2 + Arg3 + Arg4 + Arg5 + Arg6 + Arg7 + Arg8 + Arg9 + Arg10 + Arg11)
psInfo.WindowStyle = ProcessWindowStyle.Hidden
System.Diagnostics.Process.Start(psInfo)
