There is no benefit to exercising an option if you have non material info unless you are goign to sell the shares after the event. If there is plenty of time until expiration of the options - its actually not a good move to exercise with no intention of realizing some gains as it destroys any "time value" left in the options and also triggers a taxable event.
The only reason to exercise is due to expiration of in the money options, or to exercise and sell. Many brokers will help insiders hedge ESO positions via short sale or doign some sort of forward buyback arrangement, but I beleive recently some transactions which were classified as a LOAN have been under scrutiny by the IRS because they unlock the $$$ in options without actually selling them.
