go - Terminating a Process Started with os/exec in Golang

Question

Is there a way to terminate a process started with os.exec in Golang? For example (from http://golang.org/pkg/os/exec/#example_Cmd_Start),

cmd := exec.Command("sleep", "5")
err := cmd.Start()
if err != nil {
    log.Fatal(err)
}
log.Printf("Waiting for command to finish...")
err = cmd.Wait()
log.Printf("Command finished with error: %v", err)

Is there a way to terminate that process ahead of time, perhaps after 3 seconds?

Thanks in advance
