A promise by the seller to stop talking to other buyers for an agreed period, so the one buyer can spend money on diligence without being outbid mid-way. Also called a no-shop. It is the point where a seller loses competitive leverage, which is why its length is negotiated carefully.
Why it matters
Due diligence is expensive, both in money and in the time a buyer's team spends on it, and no
buyer wants to spend that while the seller is still shopping the deal to someone else. Exclusivity
— sometimes called a no-shop — is the seller's promise to stop talking to other buyers for an
agreed period so the one buyer can do that work without the risk of being outbid mid-way through.
For a founder, this is the moment real competitive leverage disappears, at least temporarily. Up
to this point, the existence of other interested buyers is what keeps a single buyer honest on
price and terms; once exclusivity is signed, that pressure is gone until it either closes or
expires.
How it works
An exclusivity clause names a period — the parties negotiate how long — during which the seller
agrees not to solicit, entertain, or negotiate with any other buyer. It is one of the few clauses
in a Letter of Intent that is drafted to be binding even though most of the rest
of the document is not, precisely because the whole point is to be enforceable while the buyer
spends money relying on it.
The period is usually matched to how long due diligence is expected to take. A shorter period
gives the seller a faster route back to the market if the deal stalls; a longer one gives the
buyer more room but leaves the seller exposed for longer if the buyer is slow, or not acting in
good faith. Extensions are common when diligence genuinely runs over, but a seller should decide
in advance what would justify granting one.
Questions people ask
- What happens if a seller breaks exclusivity?
- It depends on what the clause says, but because exclusivity is usually one of the genuinely binding parts of a letter of intent, breaking it can expose the seller to a claim for damages or the buyer’s costs, even if the rest of the letter was non-binding. It is treated far more seriously than most of the surrounding document.
- How long should an exclusivity period last?
- Long enough for the buyer to realistically complete due diligence, and no longer, since every extra week is a week the seller cannot talk to anyone else. Matching the period to the actual scope of the diligence being planned, rather than accepting a buyer’s default request, is the more defensible approach.
- Does exclusivity mean the deal will definitely close?
- No. Exclusivity only restricts who the seller can talk to during the period; it does not obligate the buyer to complete the purchase, and diligence can still reveal problems that cause the buyer to walk away or renegotiate. It removes competing pressure, not the risk that the deal falls through.
