At the request of Pax, Somes and Tabor became cosureties on a loan from Cox to Pax. At the time they agreed to become sureties, Somes placed a limit of $30,000 on his liability, and Tabor placed a limit of $20,000 on his; the loan was in the amount of $30,000. Somes and Tabor mutually intended to be cosureties, and each promised to pay the loan to the extent of the limit placed should Pax default on payment at maturity. Based on these facts, Insolvency of Somes would discharge Tabor. Bankruptcy of Tabor before maturity of the note would limit Somes' potential liability to $18,000. A release of Somes by Cox, reserving Cox's rights against Tabor, would not reduce Tabor's obligations. A release of Tabor by Cox would result in a complete discharge of Somes
