I have a product on which i am willing to take an agreement with my company

Unfortunately, this is off-topic, but I can share a few thoughts and observations. Companies with good legal support have the mechanism providing exclusions from the usual non-disclosure agreement employees sign with the administration. When you prepare the documents related to your agreements, you can amend the standard company document with the exclusions, based on the fact that you have your very own works you wish to share with your company (if you don't share anything, it simply would not make any sense). If such procedure is not used in the company, I think you should insist that such document should be created and signed by both sides.

Essentially, you may wish to share your works with the company by licensing your works on non-exclusive basis. Only then you can secure your ownership for your own works. At the same time, the company would hardly agree to use your works if you want to impose some limited access to them. In reasonable settings, both sides should be interested in maximum freedom for both sides. However, forum on software legal issues are full of pathological cases where employees tend to effectively lose their asserts; this is the ugly fact of life, and it depends on legislation. I hope such cases are rare, but who knows what may happen when it comes to considerable money? :-(

Here, I'm touching the area where I am quite incompetent. The usual consensus on this topic is that you really need to talk to a competent lawyer.

Disclaimer: in this answer, I only express my own opinion and vision of the problem, the view of an incompetent person, so I cannot take any responsibility, in any form, for any part of my advice.
