Depending on the volume of data going between offices, you might perhaps find some way to reduce the volume of data transfered between the offices.

Here is an example: if the vpn take 2/2 of the bandwidth, it will use 2/2 on both link and then on the link of office1, there will still be 28/3 but on link of office 2, that should only leave 8/0. As you might know tcp is a protocol that send and receive acknowledgment when sending or receiving data. So you need to have upload bandwidth to be able to use properly all your download one and if the link is saturated by the vpn the acknowledgment packets sent by computers of office2 doesn't reach the web servers they are browsing (as there were 0 upload bandwidth left).
To resolve this kind of problem, you need to use traffic shapping and QOS if you didn't manage to reduce the volume of data sent and received between offices.
