USDA Pledge Account?

We have a cooperative that is working with the USDA t borrow funds. They want the bank to enter into the agreement with the cooperative and USDA. We have never done this and it seems to be like a pledge account that the bank is just agreeing to not have right of set off of funds and that we abide by the rules of USDA. Are there any questions we need to ask them before opening other than if it is an interest bearing account and if it is supervised with a USDA countersignature? Don't we need a distribution agreement from USDA? Are there any special requirements that the bank has to do involving the account?
