am I entitled to my employee termination package if the company I work for gets purchased by another company?

A complete and accurate answer to your question is not possible without futher information and documentation.  However, in general, unless you have some pre-exixsting right (contract, ee handbook) to a severance package, you are not entitled to any serverance or termination benefits (other than unemployment) if you are fired. In connection with many mergers or company sales, there is often a contract requirement that the selling company fire all of its employees and let the acquiring company offer jobs to as many of those terminated employees as it wishes.  If you received an offer letter rather than a termination package, it may mean that the acquiring company wants or needs your services.  If you decline that offer, that does not mean you are entitled to a severance package from your current employer - not to say you can't get it if you ask - just likely not entitled to it. Best to find out if you can be eligible for the termination package before you turn down the employment offer.
