Justee's AI-powered stock option agreement review tool analyzes incentive stock options (ISO), non-qualified stock options (NSO), restricted stock units (RSU), and SARs for IRC § 422 compliance, post-termination exercise windows, vesting cliffs, acceleration on change-of-control, and 83(b) election triggers. The tool flags ISO grants exceeding the $100,000 annual limit (recharacterized as NSO), post-termination exercise windows shorter than market (90 days is common but punitive), single-trigger vs. double-trigger acceleration imbalances, and exercise prices below current 409A fair-market value. Justee evaluates clawback provisions, transfer restrictions, and right-of-first-refusal terms. Stock options are the most common form of startup compensation and the most commonly misunderstood. Common option-agreement issues include under-priced grants creating 409A penalties, exercise periods so short employees forfeit vested options at termination, and acceleration provisions that benefit the company at the employee's expense. Professional option review preserves equity value.

Justee recently analyzed a 320,000 ISO grant vesting over 4 years with 1-year cliff for a senior engineer joining a Series B AI startup in Seattle, WA.
Issue Found: The post-termination exercise window was 30 days — meaning at any termination the employee had 30 days to come up with potentially $200k+ in cash to exercise vested options or forfeit them entirely. Acceleration on change-of-control was single-trigger only on involuntary termination, but the definition of "for cause" included "any failure to perform satisfactorily."
Justee Recommendation: We negotiated to a 10-year post-termination exercise period (early-exercisable to NSO conversion automatic), tightened "cause" to specific enumerated grounds, and added double-trigger acceleration on a change of control followed by termination without cause within 12 months.
"Optionee shall have thirty (30) days following termination of service to exercise vested Options. Unexercised Options shall be forfeited."
"Optionee shall have ninety (90) days following termination of service to exercise vested Options if termination is voluntary, and ten (10) years from the original grant date to exercise vested Options if termination is involuntary without Cause. Options that lose ISO treatment due to extended exercise period shall convert to NSOs."
Why it matters: Standard 30-day windows force employees to forfeit valuable equity at the worst possible time. Extended windows are increasingly common at top companies and don't materially harm the issuer when paired with proper disclosure.
