On Wednesday, the court of additional district and sessions judge delivered the verdict over the 2011 road crash with the defendant on the docks.
The court found the bus driver Jamir Hossain guilty and ordered life imprisonment.
He has been also fined Tk 5,000, failing to pay which will result in another three months in jail.
Over a separate charge pressed under penal code's Section 427 for mischief causing loss or damage, the convict has received a two-year prison term.
The convict has to pay a Tk 2,000 fine for the offence or else will have to spend a month in jail, said Prosecutor Islam.
Hossain, who was out on bail, has been taken to prison after the verdict was announced on Wednesday.
The accident occurred when the bus hit a car on the Dhaka-Aricha Highway at Manikganj's Ghior Upazila on Aug 13, 2011.
Mishuk Munier, a former journalism teacher and reputed cinematographer, was the then CEO of Dhaka-based TV channel ATN News.
They were on their way back to Dhaka from Manikganj after visiting a shooting location for the new film.
The three others killed in the crash were the car's driver 'Mustafiz', Tareque's production manager 'Wasim' and staffer 'Jamal'.
Tareque's wife Catherine, painter Dhali Al-Mamun and his wife Dilara Begum Jolly, and Tareque's production assistant Saidul Islam sustained injuries.
The local police started a case against the driver of the 'Deluxe Paribahan' bus and two days later, he was arrested from Meherpur.
Hossain had then claimed the other vehicle's driver was responsible for the accident.
A probe by the communication ministry found that both drivers have been negligent.
The trial started in September the same year after the court indicted Hossain, who secured bail in late 2011.
The prosecution produced 24 witnesses, including three policemen during the trial.
On Feb 19 this year, the trial concluded when the court fixed Wednesday for the verdict.
