Road Biking Exercise

Biclycle way that I should buy a Trek 1.2 or Giant OCR 2 '08 models?
I'm looking to get into cycling for exercise and occaisonal (not competitive) race. I want a solid entry level road bike. I have reduced my choices to these two bikes and are very similar although I wondered if anyone had an opinion on the bike, it would be a better buy for me.
I just answer a similar question a few minutes ago. So I copy the answer hope that helps you too: More than one brand to buy a bike. Your bike! That means you have good options (and anyone could add others to its list). But most important is that one of them fit better and more responsive to the riding is going to do. Go to a good bike shop and let them te advise. Try the bikes, "feel", see what they "communicate" to you. Then ask all you need, then ask some more. After of counseling, testing and question, you will be able to answer the question yourself: What bike? Enjoy the process!
