Exclusivity (the "no-shop period") is a binding commitment by a seller — almost always granted in the letter of intent — not to solicit, negotiate or accept competing offers for a defined window while the chosen buyer completes confirmatory diligence and negotiates the definitive agreement. It is typically 30 to 90 days and is one of the few genuinely binding provisions in an otherwise non-binding LOI.

Why each side wants or resists it

  • The buyer needs it. Confirmatory diligence and a buy-side QoE cost real money — often well into six figures — plus legal and advisory fees. No buyer will spend that against the risk of being outbid at the last minute. Exclusivity protects that investment.
  • The seller gives up leverage. The moment exclusivity begins, the auction ends and the seller's competitive tension collapses. The seller is now negotiating with a single counterparty who knows there is no immediate alternative — which is precisely the condition under which a buyer may attempt to re-trade (cut the price) on diligence findings.

This trade-off is why advisers fight to delay exclusivity (keeping multiple bidders live as long as possible) and to limit it when granted.

Negotiating the terms

Sellers reduce the downside of exclusivity by tightening it:

  • Short and milestone-tied. A shorter period — with extensions only if the buyer hits agreed milestones (financing commitment, diligence progress).
  • Hard expiry. Automatic termination if the deal is not signed by a date certain, restoring the seller's freedom.
  • Conduct conditions. Exclusivity may lapse if the buyer materially lowers price or worsens terms from the LOI — a guard against bad-faith re-trades.
  • Reverse break protections. In larger deals, a buyer that walks may owe a fee.

Exclusivity, no-shop and go-shop

The terms are related but distinct:

  • Exclusivity / no-shop — the seller cannot shop the deal during the window. Exclusivity in an LOI is the lower-middle-market form of the no-shop clause.
  • Go-shop — the opposite: a negotiated exception (common in PE-led public deals) that lets the seller actively solicit better offers for a short period after signing.

Practical significance

Granting exclusivity is the single biggest inflection point in a sell-side process — the seller's leverage peaks the instant before it is signed and falls sharply after. A seasoned seller therefore treats exclusivity as something the buyer must earn with a strong, well-supported LOI, not as a routine courtesy.
