What Is an Exclusivity Clause in a Contract?

An exclusivity clause says one party will deal only with the other for a certain product, service, territory or customer group — and not with anyone else — for a set time. It closes doors for the side giving it, so the end date and what it gets in return both matter.

Why it matters

Exclusivity has value, and it also closes doors. The side giving it should know what it gets in return and how long the door stays shut.

How common is it?

In the 510 public-company commercial contracts of the CUAD dataset (The Atticus Project, CC BY 4.0), 180 (35.3%) contain exclusivity.

Among contract types with at least 20 contracts in the set, it shows up most in distribution agreements (21 of 32), development agreements (17 of 29) and endorsement agreements (14 of 24).

These are larger-company deals, not a sample of every contract — a reference point, not a rule. Full method: /data/cuad.

What to watch for

Exclusivity with no end date, or one that renews automatically.
A broad definition of the “field” or “territory.”
No minimum performance from the side receiving exclusivity.

A realistic example

A regional distributor gets exclusive rights to a product line. Sales stay low for two years, and the manufacturer has no way to appoint anyone else in that region.

What to ask for

A time limit and a clear definition of the field or territory.
Minimum targets — if they are missed, exclusivity ends while the contract continues.
