Arduino Motor Driving Circuit.... What do you think?

I have one I/o pin going to a relay dpdt http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=843649 i then determines forwards or reverse. Then a second I/0 line to a NPN transitor to turn the motor of or on. This would have the capability of just forwards reverse and off. This is good because it takes on two i/o lines and is able to have just those parts because the coil would be able to run of the  40 mA the arduino pin can source
