Setting Up an Employee Stock Option Plan (ESOP) for Your Delaware C Corporation

An Employee Stock Option Plan (ESOP), also commonly called an Equity Incentive Plan or Stock Option Plan, allows your Delaware C Corporation to grant stock options to employees, advisors, and consultants. It is one of the most powerful tools for attracting and retaining top talent at an early-stage startup.

Why Set Up a Stock Option Plan?

Cash compensation at early-stage startups is often limited. A well-structured stock option plan allows you to:

• Attract experienced talent who would otherwise demand higher salaries
• Align employees' interests with company growth
• Retain key team members through vesting schedules
• Offer potential upside when the company grows in value

How Stock Options Work

A stock option gives an employee the right to purchase shares in the company at a fixed price (the exercise price or strike price) at a future date. Options are not shares themselves — they are the right to buy shares at a predetermined price.

Example:

• Employee receives options to buy 10,000 shares at $0.10 per share
• Company later valued at $10 per share
• Employee exercises options: pays $1,000, receives shares worth $100,000

The Option Pool

Before granting options, your company must set aside a pool of shares reserved for future grants, known as the option pool or employee pool.

• Typical option pool size: 10% to 20% of fully diluted shares
• Investors often require a minimum option pool before closing a funding round
• The pool should be approved by the Board of Directors and reflected in your cap table

Vesting Schedules

Options vest over time to incentivize long-term commitment. The most common vesting schedule is:

• 4-year vesting with a 1-year cliff
• The cliff means no options vest until the employee has worked for 1 full year
• After the cliff, the remaining options vest monthly or quarterly over the next 3 years

Example: An employee with 48,000 options on a 4-year/1-year cliff schedule:

• After 1 year (cliff): 12,000 options vest
• Months 13-48: 1,000 options vest per month

Types of Stock Options

Incentive Stock Options (ISOs)

• Only available to employees (not advisors or contractors)
• Preferential tax treatment if holding requirements are met
• Subject to a $100,000 per year limit on vesting value

Non-Qualified Stock Options (NSOs or NQSOs)

• Can be granted to employees, advisors, consultants, and directors
• No special tax advantages
• More flexible than ISOs

Key Documents Required

To establish a stock option plan, you will need:

1. Equity Incentive Plan document — the legal plan governing all grants
2. Board resolution approving the plan and option pool
3. Stockholder approval (for ISOs)
4. Option Grant Agreement — individual agreement for each grantee
5. Exercise Agreement — used when an employee exercises their options

409A Valuation

Before granting stock options, the IRS requires that the exercise price be set at Fair Market Value (FMV) of the company's common stock. To establish FMV for a private company, you should obtain a 409A valuation — an independent appraisal of your company's common stock.

• Without a valid 409A valuation, options may be deemed below FMV
• This can result in significant adverse tax consequences for employees
• 409A valuations typically need to be refreshed every 12 months or after major financing events
