International Underwater Contractors, Inc. (IUC), entered into a written contract with New England Telephone and Telegraph Company (NET) to assemble and install certain conduits under the Mystic River for a lump sum price of $149,680. Delays caused by NET forced IUC’s work to be performed in the winter months instead of during the summer as originally bid, and as a result, a major change had to be made in the system from that specified in the contract. NET repeatedly assured IUC that it would pay the cost if IUC would complete the work. The change cost IUC an additional $811,810.73; nevertheless, it signed a release settling the claim for a total sum of $575,000. IUC, which at the time was in financial trouble, now seeks to recover the balance due, arguing that the signed release is not binding because it was signed under economic duress. Is IUC correct?
