What this chapter covers

What exclusivity, no-shop and no-talk undertakings commit a seller to, how duration and milestones are negotiated, and which remedies apply when they are breached.

Key takeaways

  • No-shop, no-talk and exclusivity cover different behaviours and deserve to be distinguished.
  • Duration is the real negotiation: exclusivity removes the seller’s competitive tension.
  • Milestones keep exclusivity from becoming a free option for the buyer.
  • Remedies matter because time, unlike price, cannot be recovered.
  • Exclusivity should follow conviction rather than be used to create it.

Once a buyer has made a credible proposal and the parties are ready to move into detailed due diligence and documentation, a difficult question often arises:

should the seller stop talking to everyone else?

For the buyer, the request is understandable. An M&A process requires significant investment in legal, financial, tax and commercial due diligence. Financing may need to be arranged, management time committed and a definitive purchase agreement negotiated.

Few buyers want to incur those costs while knowing that the seller can continue negotiating with competitors and potentially use their offer to create a better auction.

For the seller, however, granting exclusivity means giving something valuable away: competitive tension.

That makes exclusivity one of the first points in an M&A transaction where legal drafting can materially change negotiating leverage.

What is an exclusivity agreement?

An exclusivity agreement — also referred to as a no-shop, lock-out or no-talk agreement — gives a prospective buyer a defined period during which the seller agrees not to pursue competing transactions.

It may appear as a binding provision of an LOI or term sheet or as a separate agreement entered into before the definitive acquisition agreement.

Its fundamental purpose is to create a protected period during which the buyer can conduct due diligence, obtain financing and negotiate the transaction without competing against another bidder.

Although the precise drafting varies, the seller may agree not to:

- solicit or encourage alternative acquisition proposals;

- initiate or continue negotiations with another potential buyer;

- provide confidential information to competing bidders;

- enter into an agreement concerning an alternative transaction; or

- in some cases, fail to notify the buyer if an unsolicited approach is received.

The restrictions may also extend to the seller’s shareholders, directors, employees and advisers so that the exclusivity undertaking cannot effectively be circumvented through another member of the transaction team.

No-shop, no-talk and exclusivity are not necessarily the same thing

The terminology is often used loosely, but the scope of the restriction can vary materially.

A no-shop provision generally prevents the seller from actively soliciting competing proposals.

A broader no-talk provision may also restrict the seller from entering into discussions with a third party that approaches it independently.

An exclusivity agreement can go further still, combining restrictions on solicitation, discussions, information sharing and entry into alternative transactions.

The distinction matters.

From a buyer’s perspective, preventing the seller from actively shopping the company may not be sufficient if the seller remains free to negotiate with any bidder that happens to approach it.

From the seller’s perspective, an absolute prohibition on responding to unsolicited proposals can be significantly more restrictive.

In public M&A, these questions can also interact with the fiduciary duties of the target’s board and with applicable takeover rules, so the contractual position cannot be considered in isolation. In private M&A, the parties generally have greater freedom to define their negotiating framework, subject to the applicable governing law.

Why buyers ask for exclusivity

The buyer’s argument is primarily one of execution risk.

Once serious due diligence begins, substantial resources are committed to a transaction that may still fail.

External lawyers review contracts and corporate records. Financial advisers analyse valuation and working capital. Tax advisers examine potential exposures. Financing providers conduct their own underwriting. Management teams spend significant time answering questions.

The buyer is therefore investing before it owns anything.

Exclusivity protects that investment by reducing the risk that another bidder can enter the process after much of that work has already been completed.

There is also a strategic consideration.

Without exclusivity, a buyer may be reluctant to reveal its strongest offer, invest in detailed structuring or commit financing resources if doing so merely helps the seller improve its position with other bidders.

A limited period of exclusivity can therefore help move a transaction from competitive exploration to execution.

Why sellers should be cautious

For the seller, exclusivity has a very different economic meaning.

Before exclusivity, the seller may have several alternatives. It may be talking to multiple buyers, testing valuation expectations or simply retaining the option to do so.

The moment exclusivity is granted, those alternatives are temporarily restricted.

That can change negotiating leverage.

Suppose a buyer offers EUR 100 million and receives six weeks of exclusivity. After four weeks of due diligence, it identifies several issues and reduces its offer to EUR 90 million.

The seller now faces a difficult choice.

It can reject the revised proposal, but the other interested buyers may have moved on. Management has already spent weeks on diligence, and restarting the process will take time.

This is one of the classic risks of exclusivity: a seller can move from a competitive process into bilateral negotiation before sufficient certainty has been achieved on price and terms.

The buyer has effectively obtained something resembling an option over the process — without yet being obliged to acquire the company.

That is why exclusivity should usually be granted in exchange for a meaningful degree of buyer commitment.

The real negotiation is often about time

An exclusivity provision is only as important as its duration.

A buyer will normally ask for enough time to complete due diligence, secure financing, negotiate the definitive agreement and obtain any approvals necessary before signing.

A seller generally wants the shortest period reasonably capable of achieving those objectives.

There is no universal correct duration.

The appropriate period depends on the complexity of the business, the status of diligence, the financing structure, regulatory requirements and how much work has already been completed before exclusivity is granted.

From an advisory perspective, however, the duration should ideally be linked to a realistic transaction timetable, not simply to an arbitrary number of weeks.

If management presentations have already taken place, the data room is complete and financing is substantially arranged, a buyer may have less justification for requesting a lengthy exclusivity period.

Conversely, a complex cross-border acquisition requiring extensive diligence may legitimately require more time.

The question is not simply "How many days of exclusivity?"

It is:

"What does the buyer need to accomplish during those days?"

Milestones can prevent exclusivity from becoming a free option

One way to balance the parties’ interests is to make exclusivity conditional on progress.

Instead of granting the buyer an unconditional period during which the seller has no alternatives, the parties may establish milestones such as:

- completion of key due diligence workstreams by a specified date;

- delivery of financing evidence;

- circulation of the first draft SPA;

- submission of comments on definitive documentation;

- confirmation of the buyer’s valuation after diligence; or

- internal investment committee or board approval.

If the buyer fails to progress the transaction, exclusivity can expire or cease to apply.

This approach can be particularly valuable for the seller because it changes the commercial logic of the provision.

The buyer is not simply purchasing time. It is receiving protected negotiating space in exchange for progressing toward signing.

That is often a better alignment of incentives.

What happens if another buyer appears?

An exclusivity agreement should also address unsolicited approaches.

A seller may agree not to solicit other bids but still receive an unexpected proposal from another party.

The contract may require the seller to reject it immediately, or it may impose a notification obligation so that the existing buyer is informed of the approach.

More buyer-friendly provisions can require disclosure of certain information about the competing proposal.

The treatment of unsolicited approaches can become particularly sensitive in public-company transactions, where fiduciary duties and takeover regulation may require greater flexibility.

In private transactions, the issue is more contractual, but still commercially important: the seller needs to understand precisely how much freedom it is surrendering before signing the exclusivity arrangement.

Remedies matter because time cannot always be recovered

A breach of exclusivity creates an unusual problem.

If the seller secretly negotiates with another bidder and signs an alternative transaction, damages may not fully compensate the original buyer for losing the opportunity.

For that reason, exclusivity agreements may contemplate equitable remedies such as injunctions or specific performance, depending on the governing law, as well as contractual claims relating to transaction costs in certain structures.

Enforceability, however, remains jurisdiction-specific.

The duration of the restriction, the consideration supporting it and the precision with which the prohibited conduct is defined can all matter. An agreement that merely requires parties to "negotiate in good faith" indefinitely is legally different from a clearly defined obligation not to negotiate with third parties for a fixed period.

Again, the label "exclusivity" is less important than what the contract actually requires.

Exclusivity should follow conviction, not create it

From an advisory perspective, perhaps the most important question is when exclusivity should be granted.

A seller may weaken its position by granting exclusivity immediately after receiving an attractive headline valuation if important elements of the buyer’s proposal remain unclear.

Before removing competitive tension, it may be sensible to establish sufficient clarity around:

- valuation and purchase price mechanics;

- transaction structure;

- financing certainty;

- material conditions;

- required approvals;

- diligence scope;

- management rollover or retention, if relevant; and

- the expected path to signing.

A buyer asking for exclusivity should therefore normally be able to demonstrate more than interest.

It should demonstrate a credible route to completing the transaction.

This is particularly important in an auction process. The seller’s negotiating leverage is often strongest immediately before selecting a preferred bidder. Once the other bidders are released and exclusivity begins, recovering that competitive dynamic may be difficult.

A well-advised seller will therefore use the moment before exclusivity to resolve as many material commercial issues as reasonably possible.

Buying time — but not the company

Exclusivity is sometimes treated as a short procedural clause sitting at the end of an LOI.

Its economic significance can be much greater.

For the buyer, it protects the time, money and resources required to convert an indicative proposal into a signed transaction.

For the seller, it temporarily gives up the ability to test the market and use competing interest to strengthen its negotiating position.

Neither side is necessarily wrong.

The purpose of the provision is to create enough stability for a serious transaction to progress, without giving the buyer an unrestricted opportunity to control the process while remaining free to walk away.

That balance depends on scope, duration, milestones and the maturity of the buyer’s proposal.

The most effective exclusivity arrangement therefore does not merely stop the seller from talking to someone else.

It creates a protected period in which the buyer is expected to move the deal forward.
