The fact that you are paid on a salary basis does not, by itself, make you exempt from overtime requirements. The fact that you are paid a salary and it's level means that you *may* be exempt, if you otherwise meet the criteria for one of the exempt categories.
You are almost certainly not an exempt "learned" professional, since that is usually those like lawyeres, engineers, doctors, etc. with advanced educational degrees, who use that education in their job. Unless you manage at least 2 others and that's a significant part of your job, you would not qualify for the executive exemption. Depending on your job responsibilities, you might be an exempt computer professional or exempt administrative employee. Here's a link to DOL summaries of the exemptions--you should take a look and see if any apply: http://www.dol.gov/whd/regs/compliance/fairpay/fact_exemption.htm
If you are not exempt, you should be paid for all hours worked, including overtime.
NYS follows essentially the same rules as the federal exemptions.
