Employee Stock Option Agreement Template

In plain language: Identifies the optionee, the number of shares covered, the option type (ISO or NSO), and the grant date.

Common mistake: Designating an option as an ISO for a non-employee or for a grant exceeding the $100,000 per-year ISO limit. The excess automatically converts to NSO treatment, and incorrect designation creates tax confusion for both parties.

In plain language: States the per-share exercise price and confirms it equals or exceeds fair market value on the grant date, referencing the 409A valuation that supports it.

Common mistake: Setting the exercise price below fair market value without a 409A valuation to support it. This creates a Section 409A violation resulting in immediate income inclusion, a 20% penalty tax, and interest charges for the employee.

In plain language: Defines exactly when options vest — typically 25% after 12 months of continuous service, then 1/48th per month for the following 36 months — and the conditions required for vesting to continue.

Common mistake: Using a vesting commencement date that differs from the grant date without documenting why. Backdating or forward-dating vesting commencement without clear documentation invites IRS scrutiny and cap table disputes.

In plain language: Describes how the optionee exercises vested options — the notice required, acceptable payment forms (cash, cashless, net exercise), and the mechanics of share delivery.

Common mistake: Omitting cashless or net exercise as a payment method for private-company options. Employees who cannot sell shares to cover the exercise price may be unable to exercise at all without this provision, effectively making the option worthless.

In plain language: Sets the maximum life of the option — typically 10 years from the grant date for ISOs — after which the option expires regardless of vesting status.

Common mistake: Setting an ISO term beyond 10 years. IRC Section 422 requires that ISOs expire no later than 10 years from grant (5 years for 10%+ shareholders). A term exceeding 10 years automatically disqualifies the ISO.

In plain language: Specifies how long the optionee has to exercise vested options after employment ends — typically 90 days for voluntary termination, 12 months for death or disability, and immediate forfeiture for cause.

Common mistake: Applying a post-termination exercise window of more than 90 days for ISOs. IRS rules require exercise within 3 months of termination (12 months for disability) to preserve ISO treatment; a longer window converts the option to NSO status.

In plain language: Defines whether unvested options accelerate upon a merger, acquisition, or other change of control — single trigger (acceleration on closing), double trigger (acceleration only if employment is also terminated), or no acceleration.

Common mistake: Granting single-trigger acceleration to all employees without considering the acquirer's perspective. Single-trigger acceleration inflates deal costs, can make the company less attractive in an M&A process, and is typically reserved for founders or C-suite executives.

In plain language: Requires the optionee to acknowledge their tax obligations, authorizes the company to withhold shares or cash to satisfy tax liabilities at exercise, and disclaims any company responsibility for tax advice.

Common mistake: Omitting withholding authorization for NSO exercises. When an employee exercises an NSO, the spread is ordinary income subject to payroll withholding — if the agreement doesn't authorize share withholding or cash collection, the company faces payroll tax liability with no mechanism to collect it.

In plain language: States that the grant agreement is subject to and governed by the company's equity incentive plan, and that together they constitute the entire agreement between the parties on equity compensation.

Common mistake: Issuing a grant agreement without an underlying plan document. Without a formally adopted plan, option grants may lack board authorization, violate state securities exemptions, and expose the company to rescission claims from employees.

In plain language: Requires the optionee to confirm they are acquiring shares for investment and not resale, and states the transfer restrictions and legend that will appear on any share certificates or book-entry records.

Common mistake: Skipping securities law representations for small private companies. Private company shares issued without registration must satisfy an exemption — typically Rule 701 or Section 4(a)(2) — and the representations in the agreement are part of the exemption conditions.

An employee stock option agreement is a legally binding contract between a company and an employee that grants the employee the right to purchase a set number of company shares at a fixed exercise price, subject to a vesting schedule. It documents the option type (ISO or NSO), grant date, exercise price, vesting terms, expiration, and what happens to the options when employment ends. It is the core document governing equity-based compensation for individual employees.

An Incentive Stock Option (ISO) qualifies for preferential US federal tax treatment under IRC Section 422 — the employee pays no ordinary income tax at exercise and may qualify for long-term capital gains rates if shares are held for the required periods. A Non-Qualified Stock Option (NSO) does not qualify for ISO treatment; the spread between exercise price and fair market value at exercise is taxed as ordinary income. ISOs are available only to employees, while NSOs can be granted to consultants, advisors, and directors as well.

A 409A valuation is an independent appraisal of a private company's common stock fair market value, required under IRC Section 409A to support the exercise price set in each option grant. If a company grants options at below-FMV prices without a qualified appraisal, employees face immediate income inclusion, a 20% excise tax, and interest charges — regardless of whether they have exercised or profited from the options. A current 409A valuation provides a safe harbor that protects both the company and employees from this exposure.

The most common vesting schedule in the US is 4 years with a 1-year cliff: no options vest during the first 12 months, 25% vest on the 1-year anniversary, and the remaining 75% vest monthly (1/48th per month) over the following 36 months. This structure aligns employee retention with a typical product or growth cycle and is the benchmark expected by most institutional investors.

Vested options typically remain exercisable for a post-termination window that depends on the reason for departure: 90 days for voluntary resignation or involuntary termination without cause, 12 months for death or disability, and immediate forfeiture in the event of termination for cause. Unvested options are forfeited on the termination date in all cases. Exercises after the post-termination window closes result in permanent expiration of the options regardless of their value.

No. An equity incentive plan is the company-level governing document adopted by the board and stockholders that establishes the option pool, defines eligible participants, sets plan-wide rules, and authorizes the types of grants permitted. A stock option agreement is the individual grant document issued to a specific employee under that plan, incorporating the plan by reference. You need both — the agreement has no legal standing without a valid underlying plan.

Not until they are exercised. A stock option is the right to purchase shares at a fixed price — the employee becomes a stockholder only when they exercise vested options by paying the exercise price and receiving shares. Until exercise, option holders have no voting rights, no dividend rights, and no direct ownership stake. The option agreement itself grants only the contractual right to buy shares in the future.

Yes, for most companies. Option agreements involve federal tax law (IRC Sections 422 and 409A), securities law exemptions (Rule 701), state corporate law, and potentially cross-border tax issues for international employees. Errors in grant date, exercise price, option type, or post-termination windows can have six-figure tax consequences for employees with no ability to correct them retroactively. A qualified startup or employment attorney typically charges $1,500–$5,000 to establish a plan and review template grant agreements, which is a fraction of the exposure of getting it wrong.

Double-trigger acceleration means unvested options vest only if two events both occur: a change of control (such as an acquisition) and an involuntary termination of the employee without cause within a defined period afterward (typically 12–18 months). Single-trigger acceleration vests options on the change of control alone, regardless of whether the employee loses their job. Most acquirers prefer double-trigger because it preserves employee retention incentives post-close and reduces the immediate cash cost of the deal.

ISOs cannot be granted to non-employees — they are limited to employees of the granting company. NSOs can be granted to independent contractors, advisors, and board members. However, grants to non-employees are subject to different securities law analysis and may require separate valuation treatment. Advisors often receive options under a separate advisor grant agreement with a shorter vesting schedule (typically 1–2 years) than employee grants.
