God-Father, in insurance speak, the duty to defend is broader than the duty to indemnify (pay any settlement or judgment), so technically speaking, Prosper may still be on the hook for paying any class action judgment, or contributing to any settlement. However, Prosper does have two very expensive law firms, and this order only goes to the payment of one of them -- the defense of the class action. Without giving Prosper any hints (its very expensive law firms know this), I would expect that any settlement of the coverage dispute will include at least a hefty contribution to coverage counsel's fees. Of course, Greenwich could appeal the coverage determination.
Gee, Moth, I'm an insurance attorney and I carpool with two bankers. I guess you don't want us at your Christmas party.

BTW, OK with me for lobby.
