Various technologies and techniques are disclosed for handling exceptions in sequential statements that are executed in parallel. A transactional memory system is provided with a contention manager. The contention manager is responsible for managing exceptions that occur within statements that were designed to be executed in an original sequential order, and that were transformed into ordered transactions for speculative execution in parallel. The contention manager ensures that any exceptions that are thrown from one or more speculatively executed blocks while the statements are being executed speculatively in parallel are handled in the original sequential order.
