Register Eventhandler`1 via late binding

Hello,

I need help in late binding.

I have a simple assembly Option.dll, which defines only two classes:

public class Option
{
    public event EventHandler<OptionEventArgs> OnBought;

    public void Buy()
    {
        Console.WriteLine("Buying option...");

        if (OnBought != null)
            OnBought(this, new OptionEventArgs("Successfully bought!", 120.50));
    }
}

public class OptionEventArgs : EventArgs
{
    public string Message { get; set; }
    public double Lots { get; set; }

    public OptionEventArgs() { }
    public OptionEventArgs(string message, double lots)
    {
        Message = message;
        Lots = lots;
    }
}

In the client app, I load an assembly dynamically and use late binding to activate the Option type, but I don't know how to register the OnBought event.

Is there any way to register it ?
Here is the client app's Main method:

static void Main(string[] args)
{
    Assembly asm = null;

    try
    {
        asm = Assembly.Load("Option");

        Type option = asm.GetType("Option.Option");
        dynamic opt = Activator.CreateInstance(option);

        //now i want to register OnBought event...
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }

    Console.ReadLine();
}

Thank you
