The buyer wants us to carry a mezzanine seller note that converts into common equity at a discounted valuation if they execute a recapitalization event. Is a convertible seller note advantageous for an exiting founder, and how should we structure the conversion triggers?

A convertible seller note can be an effective vehicle to secure a second bite at the apple if you are selling to a high-growth platform or private equity firm, but only if you maintain control over the conversion mechanics. Without tight structural guardrails, a buyer can use a convertible note to leave you with unpaid debt if the business struggles, while diluting you into worthless minority equity right before an exit.

To make a convertible seller note genuinely advantageous, negotiate these critical terms:

- The conversion must be seller-optional, not buyer-mandatory. The buyer should never possess the unilateral right to force your debt into common equity. You must retain the exclusive option at a qualified recapitalization or sale event to either take your full remaining principal and accrued interest in cash, or convert into equity.
- Establish a valuation floor and discount cap. The agreement must explicitly define the valuation mechanics. If you convert, you should convert at a defined discount (typically 15 to 25 percent) to the enterprise value set by the new institutional investors, subject to a fixed valuation ceiling so your equity percentage is protected against runaway dilution.
- Set a minimum maturity deadline. The note must carry a standard maturity date (typically four to five years) with regular cash pay interest (eight to twelve percent) regardless of whether a liquidity event occurs. If the buyer never refinances or sells, your debt matures and must be settled in cash.
- Require pari passu equity rights upon conversion. If you exercise your conversion option, your shares must enter the capitalization table on the exact same class, voting rights, and liquidation preference terms as the lead institutional sponsors, not subordinated common units subject to management clawbacks.
