I'm not sure how to calculate the interest expense on bonds.

My question: on January 2, 2008 a company issued $500,000, 10 year bond for $574,540. The bonds pay interes on June 30 and December 31. The face rate is 8% and the market rate is 6%. The interest expense on the bonds at June 30 2008 is?

Can you get me started.
I feel like it pretty easy, but I can't figure it out...

Thanks in advance.
