Narrative:

Upon landing at bos, runway 4R, tower controller advised us if we couldn't make the runway 33R turnoff to expedite to the end to exit runway. Copilot landed the aircraft, and made a maximum effort to slow the aircraft enough to make the runway 33R 90 degree turn. I advised tower that we had turnoff assured, at which point he hurriedly advised us to hold short of runway 4L and monitor 128.8. I hurriedly acknowledged. A small cpr jet was taxiing in front of us and taxied across runway 4L. Copilot missed the hold short runway 4L instructions and missed frequency change, so I looked down as I put 128.8 in other head of VHF #1 radio. When I looked up, I had already passed the runway markings for runway 4L and could not stop in time to hold short of runway, so added power to cross as fast as possible. Once past runway 4L, tower controller on runway 4L told us to monitor ground control. Nothing further was said. Fatigue was a definite factor. WX in northeast corridor was bad. Radio chatter at the time was excessive on both approach and tower frequencys. I had to check in a number of times on approach, after landing clearance from tower, chatter continued. This was third day of 4 day trip with many WX delays, late arrs, etc. We were both extremely tired.
