Correct me if I am wrong, the contract should really be a non-issue. The way I think about it is as follows:

1-I would be at a regional for more than 2 years anyway, maybe longer.
2-I believe the agreements with Jet Blue and Spirit make Cape Air the
fastest way to a wide body jet.
3-from all the research I have done on their website making Capt is
assured as soon as you have your ATP mins. And I believe the
Capt's are making decent money.
4-I am excited about the fleet replacement! You can really tell the
state of a company when they are willing to replace the entire fleet of airplanes.

I believe the contract is worth it! I plan on staying there longer than the 15 months they are obligating me to. Heck maybe much longer if I get to fly out of San Juan!
