Legal Question in Business Law in Pennsylvania

if the delivery of the old mold is a prerequisite of the Seller making a new mold then the obligation of the Seller cannot begin until the mold is delivered. What does the contract say if says must be delivered by a certain date and not delivered by that date that may void the contract if no date is specified then in a reasonable period is implied. if the mold was received in a reasonable amount of time obligation may still exist. All this depends on an interpretation of the terms of the contract or if not provided then under applicable rules of interpretation. I suggest you review the facts and contract with an attorney to get a more through opinion of how the facts apply to your situation.
