Quick answer: An exclusivity, or no-shop, provision in a letter of intent bars the seller from soliciting, negotiating with or sharing information with other buyers for an agreed period. It is usually the binding part of an otherwise non-binding letter, and it ends the seller’s competitive leverage. Sellers negotiate its length, the milestones the buyer must meet to keep it, what happens if the price changes, and how it extends, so that the period matches the buyer’s real diligence plan.
Key points
- Exclusivity is usually the part of a letter of intent that binds. Price and terms can change, but the seller’s promise not to talk to other buyers holds.
- Length is a trade. A longer period gives the buyer comfort to spend on diligence and lengthens the time the seller has no alternative if the price moves.
- The protections that matter are dated milestones, a right to end exclusivity if the price or key terms change, conditional extensions and a precise definition of what the seller may not do.
- A backup bidder can be kept warm only within the clause. Read what solicit, negotiate and discuss each cover before relying on any workaround, and ask counsel before any contact.
What a no-shop clause restricts
Exclusivity, often called a no-shop, is the seller’s promise in the letter of intent not to seek or entertain other deals for a stated period. It exists because the buyer is about to spend heavily on accountants, attorneys and other advisors for a company it does not own, and it will not do so if the seller can carry that work to a competing bidder. The cost to the seller is the end of the competition the process created. The price and structure in a letter are generally non-binding while exclusivity is generally written to bind, so the clause deserves the negotiating effort that the price gets. The guide to reading a letter of intent places it among the other terms.
The table lists the provisions that make up a typical clause and what a seller negotiates in each.
| Provision | What it does | What a seller negotiates |
|---|---|---|
| Restricted activity | Bars soliciting, negotiating with or giving information to other buyers or financing sources about a sale | A precise list of covered transactions, with carve-outs for ordinary dealings with lenders, customers and suppliers |
| Who is bound | The company, its owners and their representatives, including the sell-side advisor | Clarity on who must stop contact and how inbound inquiries are answered |
| Length | The period from signing to a stated end date | A period built from the buyer’s diligence plan, not from custom |
| Extensions | Automatic, or by agreement | A written request, a confirmed price and milestones met, with a limit on how many |
| Termination rights | Whether the seller may end exclusivity early | A right to end it if the price or key terms change or milestones are missed |
| Notice of inbound approaches | Whether the seller must tell the buyer about other proposals | A duty limited to saying an approach occurred, without the other party’s name or terms |
| Remedies | What the buyer may seek if the seller breaches | Review by counsel, so the exposure is proportionate |
What counts as a covered transaction deserves a close read. A clause that reaches any sale, merger, recapitalization or financing that could change control may also catch a minority investment or a refinancing the owner was planning. Counsel can carve those out when the letter is signed and usually cannot afterward.
Setting the length from the buyer’s plan
The right length is the time the buyer needs to finish a defined plan, plus a buffer. It is not a customary number. The seller asks the buyer to write out the steps: the financial review, legal and tax review, operational checks, any third-party reports, the financing and the approvals needed before it can sign. A step the buyer cannot date is a step it has not planned. The dependencies that stretch those steps are described in the guide to how long a sale takes.
The trade-off runs in both directions. A longer period lets the buyer spend with confidence and lowers the odds that it asks for an extension at the end, but it lengthens the time during which the seller has no alternative if the buyer lowers the price. A shorter period keeps pressure on the buyer and limits exposure, but it forces an extension request at a point when the buyer holds the leverage. The usual answer is a shorter initial period and an extension that is earned by performance.
Illustrative example: A milestone schedule that earns the extension
A buyer asks for 90 days of exclusivity. The owner proposes an initial period of 60 days and one extension of 30 days, available only if every milestone below was met and the buyer confirms in writing that the price and key terms are unchanged. The buyer can still have the 90 days it asked for, but only by performing.
| Day after signing | Milestone the buyer must meet | If missed |
|---|---|---|
| 10 | Delivers its full diligence request list and names its accounting, legal and tax advisors | Owner may end exclusivity by written notice |
| 30 | Delivers a first draft of the purchase agreement and a first set of financial findings | Owner may end exclusivity by written notice |
| 45 | Provides written evidence of committed financing | Owner may end exclusivity by written notice |
| 60 | Initial period ends | Extension to day 90 if all milestones were met and the price is confirmed |
Under this schedule the owner is bound to a buyer that has stopped performing for no more than a few weeks, not for the full period. The schedule, the days and the terms are invented to show the mechanics and are not benchmarks. Whether a buyer accepts such terms depends on its leverage and on how competitive the process was.
What a seller can ask for in return
Exclusivity costs the seller its alternatives, so it is a term to be paid for, not given away. How much a seller can ask depends on the process that came before. Close first-round offers and a runner-up that is still interested, the situation described in the guide to comparing indications of interest, make the requests credible.
- Dated milestones. Each is a deliverable from the buyer, such as the request list, a first draft of the agreement or evidence of funding. Missing one lets the seller end exclusivity.
- An exit on a price change. The seller may end exclusivity if the buyer proposes a lower price or materially different terms that are not tied to a specific diligence finding explained in writing. The guide to retrades explains why this clause matters.
- Evidence of funding. A committed equity source or a lender’s commitment early in the period, so the seller is not bound while the buyer is still looking for money.
- Earned extensions. A shorter initial period, with extensions available only on milestones met.
- A deposit or expense reimbursement. Money the buyer forfeits or pays if it withdraws without cause, which tests its seriousness. Whether a buyer agrees depends on its size and leverage, and counsel drafts the conditions.
- Narrow scope. Carve-outs for ordinary-course dealings and for activity unrelated to a sale.
- Progress reports. A regular status report on diligence, so the seller sees problems before the end date.
Expiry, extension requests and price changes
When the period ends, the seller’s freedom returns unless both sides extend. Buyers often ask for an extension when diligence is nearly finished, which is the moment the seller has the fewest alternatives, because other bidders have moved on. The seller has three responses. It can extend on conditions: price and key terms confirmed in writing, the remaining milestones dated, perhaps a deposit. It can decline and resume talks with other bidders, which is credible only if a runner-up was kept interested. Or it can let the period lapse and see whether the buyer speeds up, which carries the risk that the buyer walks.
A price reduction during exclusivity puts the same choice earlier. The seller can ask which finding justifies the change, what documents support it and whether a narrower fix, such as an escrow or a specific indemnity, answers the same concern at lower cost. If the answers do not hold, a right to end exclusivity returns the leverage. Without that right, the seller can only refuse and wait for expiry. The reasons buyers reduce price are covered in the guide to retrades after the letter of intent, and the causes that end a sale altogether are collected in the guide to why business sales fall apart. Counsel should raise an extension request with the owner well before the end date, not on the last day.
Keeping a backup bidder warm without breaching
The work is done within the clause, not around it. A breach can give the buyer a legal claim and will end its trust, and the seller’s advisor is bound along with the seller. The seller’s attorney should read the clause before any contact with another buyer.
- Read the verbs. Solicit, negotiate, discuss and provide information are different acts. A clause that bars only solicitation and negotiation leaves more room than one that bars any discussion about the company.
- Negotiate the carve-out at signing. Ask for the right to answer an unsolicited inquiry by saying the company is not available, and to continue ordinary relationships with customers, suppliers and lenders.
- Preserve the record before the clause starts. While the runner-up is still in the process, ask whether it will keep its indication of interest open if the process pauses, and file its written answer.
- Close courteously. Tell other bidders, in one standard message, that the process has moved to its next phase. Name no buyer and state no terms.
- Keep the file current. Hold the buyer list, the signed confidentiality agreements and an updated information memorandum ready, so a restart after a lapse or a termination does not begin from nothing.
- Use no informal channels. If the buyer retrades or the period ends, counsel decides how and when contact resumes.
The overview of the sale process shows where exclusivity sits among the stages, and the guide to how to sell a business covers the decisions on either side of it.
Frequently asked questions
What is an exclusivity period in a letter of intent?
A stated period during which the seller agrees not to solicit, negotiate with or give information to other potential buyers or financing sources for the company. It gives the buyer time to complete diligence without being outbid midway. The price terms in the letter may be non-binding, but the exclusivity clause is usually written to bind, so an attorney should read it before signing.
How long should exclusivity last?
Long enough for the buyer to finish diligence and the purchase agreement under a realistic plan, and no longer. Ask the buyer to list the steps, who performs each and what must be done before it can sign, then size the period to that plan. A period shorter than the plan forces an extension request, and a much longer one removes the buyer’s reason to move quickly.
What happens when exclusivity expires?
The seller is free to talk to other buyers again unless both sides agree to extend. A buyer that is nearly finished often asks for an extension, and the seller can condition it on milestones met, a confirmed price or a deposit. If the buyer has lowered the price, the seller can decline and reopen the process, which is easier if a runner-up was kept interested.
Can the seller talk to other buyers during exclusivity?
Not about a sale of the company, if the clause bars solicitation, negotiation and discussion. Some clauses let the seller answer an unsolicited approach by saying it is bound. Whether and how a backup bidder can be kept informed depends on the exact wording, so ask the seller’s attorney before any contact.
Can a seller ask for anything in return for exclusivity?
Yes, because exclusivity costs the seller its alternatives. Common requests are dated milestones, a right to end exclusivity if the price or key terms change, evidence of financing, a deposit or expense reimbursement if the buyer withdraws without cause, and a shorter initial period with extensions earned by progress. What is realistic depends on the buyer and on how competitive the process was.
