You can learn things better and gain experience. But I suggest do not continue to stay longer as they do not pay you at par with industry standards. Your job will be a secured one . But over a period of time you will feel the frustration when you see your salary hike at the year end. This will continue year on year. You can expect promotions as per your performance based on that your roles & responsibilities will increase, but not your salary. They will give you what ever position you need, what ever roles , designation you need , but not the salary you need.
