hereto agree as follows:

       2.     ENGINE TYPE - The V-Twin engine to be supplied by Patrick Racing
              to Viper shall be the 128" V-Twin which will be developed by
              Patrick Racing. Promptly upon execution of this Agreement by both
              parties hereto, Patrick Racing shall ship one complete polished
