You can do DR Site with OSPF.At site 1, the 2 internet links are of unequal capacity & diference in BW is also more. If u do load-balancing, 1Mbps may be choked throughout the day whereas 5Mbps may not have much on it. It is better to use the 2 links in active /backup configuration using either static routes with AD in case of single ISP, or BGP if multihoming.
