If they are non-qual options, why not make them 10 years like other companies. Why the short expiration? I'd rather have ISOs and the chance to cut my tax burden in half. More importantly not having to pay taxes upfront to exercise the options. Doesn't seem employee friendly.
They are ISOs. The standard PTE for most companies is 90 days.
Because 90 days is the IRS rule for options to qualify as ISOs.
