(2) If the creditor does not have the right to exhaust the security or has not done so, upon the amount of the claim allowed less the value of the security determined by converting it into money according to the terms of the agreement pursuant to which the security was delivered to the creditor, or by the creditor and personal representative by agreement, arbitration, compromise, or litigation.
