Creepy! I'm not at all clear on how this allows the business owner to save tax-free for retirement. If the business did collect, or even if they decided to surrender the policy at some future date, wouldn't they just have to pay the money out to the owner in some taxable fashion? Whether it's as regular income, a bonus, or a dividend, it's still taxed.
If I were you, I would want to figure out how it worked. Maybe she's willing to trade you something for this privilege? I'd also be very skeptical of any situation where someone else has a strong financial incentive for me to die.
