Exclusivity Clauses in a Business Sale LOI: What Ontario Sellers Give Up

Signing an exclusivity clause in a letter of intent means agreeing not to talk to other buyers. Here's what Ontario sellers should understand first.

Key takeaways
  • At its core, an exclusivity (or no-shop) clause commits the seller not to solicit, negotiate with, or accept offers from other prospective buyers for a defined period after signing the LOI.
  • A buyer doing due diligence on a private business commits real time and cost before knowing whether the deal will close.
  • For as long as exclusivity runs, you can't pursue or even respond meaningfully to other interested buyers — including ones who might offer more.

Most of a letter of intent isn't a binding contract. Price, structure, and most commercial terms in an LOI are typically framed as non-binding, subject to a definitive purchase agreement. An exclusivity clause — sometimes called a "no-shop" provision — is different. It's one of the handful of LOI terms commonly drafted to be binding from the moment you sign, even though the rest of the deal isn't locked in yet.

That distinction matters. Agreeing to exclusivity means giving up your ability to talk to other buyers while the current one does its due diligence, with no guarantee at that point that the deal will actually close.

This article explains what an exclusivity clause typically requires, why buyers ask for it, what it costs a seller, and what to negotiate instead of trying to pin down a "standard" length.

What an Exclusivity Clause Actually Requires

At its core, an exclusivity (or no-shop) clause commits the seller not to solicit, negotiate with, or accept offers from other prospective buyers for a defined period after signing the LOI. Depending on how it's drafted, it may also require the seller to stop actively marketing the business, and sometimes to disclose any unsolicited approaches that come in anyway.

Why Buyers Ask for It

A buyer doing due diligence on a private business commits real time and cost before knowing whether the deal will close. Exclusivity protects that investment by removing the risk that the seller uses the buyer's offer as leverage to shop for a better one, or simply keeps multiple conversations alive at once. From the buyer's side, it's a reasonable ask in exchange for taking the deal seriously.

What a Seller Gives Up

Binding vs. Non-Binding: Where Exclusivity Sits

LOI provisionTypically binding?
Purchase priceNo — subject to the definitive agreement
Deal structure (share vs. asset)No — subject to change through negotiation
ConfidentialityOften yes
Exclusivity / no-shopOften yes
Allocation of due diligence costsOften yes
Governing law for the LOI itselfOften yes

This mixed structure is exactly why an LOI needs a lawyer's review before signing — treating the whole document as "non-binding, so it doesn't matter" misses the provisions that genuinely do bind you.

What to Negotiate, Instead of Asking "How Long Is Typical?"

There's no fixed or standard exclusivity period — it's negotiated deal by deal, and any figure you see quoted elsewhere as "typical" should be treated with caution. What's more useful than chasing a number is negotiating the structure around it:

  1. A defined end date, rather than an open-ended commitment, so exclusivity doesn't quietly extend indefinitely.
  2. A mechanism to extend only by mutual written agreement, not unilaterally by the buyer.
  3. Clear termination triggers — for example, the right to walk if the buyer misses its own diligence milestones.
  4. A carve-out for unsolicited inbound approaches, even if you can't actively solicit them, so you're not contractually blind to a materially better offer that shows up on its own.
  5. Scope limits, so exclusivity applies to selling the business, not to unrelated activities like ordinary financing discussions.

Frequently asked questions

Can I still talk to a buyer who approaches me out of the blue during exclusivity?

It depends entirely on how the clause is drafted. Some exclusivity provisions only prohibit you from soliciting other buyers, while others go further and prohibit even discussing an unsolicited approach. Know which version you've signed before you take a single call.

What happens if I breach an exclusivity clause?

Consequences depend on the LOI's own terms — some include a specific remedy or cost-reimbursement provision, while others leave the buyer to pursue a breach-of-contract claim generally. Either way, breaching a binding provision you agreed to is a real legal risk, not a technicality.

Does exclusivity mean the deal will definitely close?

No. Exclusivity only restricts your ability to talk to others — it doesn't obligate the buyer to close, and most other LOI terms remain non-binding and subject to negotiation and due diligence. A deal can still fall apart after exclusivity is granted.

Should I ever refuse to grant exclusivity at all?

It's a legitimate negotiating position, especially if you have genuine competing interest from multiple buyers. Whether it's the right call depends on your specific situation and how much leverage you actually have — this is worth discussing with your lawyer before you respond to a buyer's request.
