thread with multiple parameters

Does anyone know how to pass multiple parameters into a Thread.Start routine?

I thought of extending the class, but the C# Thread class is sealed.

Here is what I think the code would look like:

...
    Thread standardTCPServerThread = new Thread(startSocketServerAsThread);

    standardServerThread.Start( orchestrator, initializeMemberBalance, arg, 60000);
...
}

static void startSocketServerAsThread(ServiceOrchestrator orchestrator, List<int> memberBalances, string arg, int port)
{
  startSocketServer(orchestrator, memberBalances, arg, port);
}

BTW, I start a number of threads with different orchestrators, balances and ports. Please consider thread safety also.
