You have just signed the agreement to sell the business you spent a decade building. The price is fair, the buyer seems serious, and your lawyer finally stops billing you for redlines. Then, two weeks later, a rival calls: they heard you are selling, and they will pay 15 percent more. Can you take the meeting? The answer is sitting in your merger agreement, in the cluster of clauses lawyers call deal protections — and whether you negotiated a no-shop or a go-shop decides if that phone call is the best thing that ever happened to you or a conversation you are contractually forbidden from having.
Why buyers demand a lock-up in the first place
Put yourself in the buyer's shoes for a moment. By the time a merger agreement is signed, the buyer has spent months on due diligence: accountants crawling through your books, lawyers reviewing every contract, bankers lining up financing. That work costs real money, and it is worthless if you take their signed offer down the street to start an auction.
Deal protections solve that problem. They are the set of promises you make, between signing and closing — a gap that typically runs three to six months — that limit your ability to find a better deal. The centerpiece is the no-shop clause, and its more seller-friendly cousin is the go-shop. Everything else in this article — fiduciary outs, superior proposals, matching rights, two-tier breakup fees — is machinery for deciding what happens when a better offer shows up anyway.
What a no-shop clause actually prohibits
A no-shop (sometimes called a no-solicitation) clause is an exclusivity promise. Once it is in effect, you agree not to shop the deal: no calling other potential buyers, no sharing confidential information with them, no soliciting competing proposals, and no negotiating with anyone who comes knocking on their own initiative.
Note how broad that is. A no-shop does not just ban you from starting an auction — it generally bars you from engaging with unsolicited interest in any meaningful way. You can usually acknowledge the call and say you are bound by an agreement, but you cannot open the data room, discuss price, or negotiate terms. The status quo in most merger agreements is a no-shop, and it typically runs from signing all the way to closing or termination.
Smaller deals often carry a lighter version much earlier. A letter of intent for a small-business sale commonly includes a no-shop lasting 30 to 90 days while the buyer does exclusivity-period due diligence. Same idea, smaller stage: the buyer wants a protected window to spend money investigating your company.
The Microsoft–LinkedIn deal is the textbook example of a no-shop at scale. When Microsoft agreed to buy LinkedIn for $26.2 billion in 2016, the agreement barred LinkedIn from soliciting competing bids — and if LinkedIn had walked away to accept a better offer, it would have owed Microsoft a $725 million breakup fee. That fee, roughly 2.8 percent of the deal value, is squarely in the normal range: termination fees commonly run 1 to 4 percent of a transaction's equity value.
The fiduciary out: the board's escape hatch
Here is the tension a no-shop creates. If you are selling a company with shareholders — or you owe duties to minority owners, partners, or investors — you cannot contractually promise to ignore a clearly better offer. Your obligation to get your owners the best deal reasonably available overrides the exclusivity you gave the buyer.
The fiduciary out is the clause that resolves this. It says: despite the no-shop, the board may engage with an unsolicited, bona fide offer if failing to do so would breach its duties to shareholders. In practice the out has a strict choreography:
- The rival bid must qualify as a superior proposal. Merger agreements define this term precisely — typically an unsolicited, credible offer for a majority of the company that the board determines, after consulting its bankers and lawyers, would deliver more value to shareholders than the signed deal. A vague expression of interest does not count.
- The board must notify the original buyer and usually share the rival's terms, giving the first bidder a chance to respond.
- The board may then change its recommendation — formally telling shareholders it no longer supports the original deal — and terminate the agreement to accept the better one.
- The seller still pays the breakup fee. The fiduciary out excuses the exclusivity promise; it does not excuse the termination payment. Walking through the escape hatch still costs the agreed fee.
So a no-shop with a fiduciary out is really a bet by the buyer that no better offer will appear on its own. The buyer is protected against an auction you run deliberately, but not against a rival who shows up uninvited with a bigger check.
What a go-shop window changes
A go-shop flips the default for a limited time. For a defined window after signing — commonly 30 to 60 days, with 45 days a frequent choice — you are affirmatively allowed to solicit competing bids. You and your bankers can call every logical buyer, open the data room, and negotiate rival proposals, all while holding a signed agreement that sets a floor under the price.
Think of the signed deal as insurance: if the market check turns up nothing better, you still close with the original buyer on the agreed terms. If it turns up something better, you switch — paying a termination fee, but a smaller one than usual (more on that below).
Go-shops show up most often where the seller never ran a real auction before signing. The classic setting is a private-equity buyout or a go-private transaction negotiated with a single bidder: the board signs first, then uses the window to demonstrate it tested the market. Investment banks typically run a structured solicitation during the window, contacting dozens of strategic and financial buyers.
One refinement worth knowing: the excluded-party tail. Bidders who surface during the go-shop window and are still negotiating when it closes are often designated as excluded parties and get a short extension — typically around two extra weeks — to finish their proposals under the go-shop's friendlier economics. The window closing does not execute a bidder mid-negotiation.
Two-tier breakup fees: the price differs by when you leave
The termination fee is what makes the no-shop/go-shop distinction bite economically, and most go-shop deals use a two-tier structure:
- Tier one (during the go-shop window): a reduced fee, often around 1 percent of equity value, owed if you terminate to accept a superior proposal that emerged from the market check.
- Tier two (after the window closes): the full fee, often around 3 percent or more, once the agreement converts into a standard no-shop for the remaining months until closing.
The logic is straightforward. During the window, the original bidder agreed to be shopped — it signed up as the floor bid in a market test — so the penalty for losing is modest. After the window, the seller promised exclusivity, so walking away costs the full amount.
Real deals follow this pattern closely. When Apple REIT Ten agreed to merge with Apple Hospitality in a $1.3 billion deal, the agreement set a $5 million termination fee (plus up to $3 million in expenses) for a superior proposal arising during the 45-day go-shop, jumping to $25 million afterward. The step-up is the point: it prices the difference between leaving during an agreed market check and leaving after promising not to.
Matching rights: the first bidder's last word
Nearly every agreement with a fiduciary out or a go-shop also gives the original buyer matching rights: before you terminate for a superior proposal, you must show the first bidder the rival's terms and give it a short window — often measured in business days — to match or beat them.
Matching rights matter more than they look. A rival bidder knows that whatever price it offers, the incumbent gets a last look and can steal the deal by matching. That dampens the incentive to bid at all — why spend millions on due diligence just to set the price for someone else? When you evaluate how real your market check is, the length and structure of the match right is one of the first things to examine, because a long match right on top of a high breakup fee can make even a genuine go-shop window mostly theoretical.
Why go-shops rarely produce a topping bid
Here is the uncomfortable data point: topping bids during go-shop windows are rare. Critics argue the windows are too short for a new bidder to do real due diligence — 45 days is not much time to underwrite a multi-hundred-million-dollar acquisition from a standing start — and that the combination of matching rights and termination fees deters all but the most determined rivals. A widely cited Harvard Law Review study of go-shop outcomes found that very few initial bids are ever displaced during the window.
Does that make go-shops cosmetic? Not entirely. Their value is partly evidentiary: a board that actively solicited competing bids during a documented window is in a far stronger position to show it satisfied its duty to shareholders than one that signed a no-shop with a single bidder and hoped. And occasionally the window works exactly as designed — a second bidder that was circling before the announcement uses the window to formalize its offer. But go into one with clear eyes: the most likely outcome is that you close with the original buyer, having paid your bankers for a market check that confirmed the price.
What this means if you are selling a small business
You will probably never sign a 200-page public-company merger agreement, but the same concepts appear in small-business sales in miniature. Practical takeaways:
- Negotiate the exclusivity window at the LOI stage. A buyer will ask for 60 to 90 days of exclusivity for due diligence. Push for the shortest period you can get, tied to milestones — exclusivity that auto-extends only if financing is actually progressing, for example.
- Define what counts as a better offer. Even in a simple deal, write down what would let you walk: a higher price is obvious, but certainty of close, all-cash versus earnout, and liability terms matter too.
- Cap the walk-away cost. Small deals do not always have breakup fees, but buyers may ask for expense reimbursement if you walk. Cap it at a fixed dollar amount rather than signing an open-ended promise.
- Keep a paper trail of your market check. If you have partners, minority shareholders, or investors, document that you considered alternatives — even informally. The same duty that justifies a fiduciary out in a big deal applies to you in proportion to your company's ownership.
- Get counsel before you sign, not after the rival calls. Once the no-shop is signed, your options are whatever the fiduciary out allows. The negotiation that matters happens before exclusivity begins.
Booking it: deal costs and termination fees in your ledger
Whatever the outcome, a sale process generates costs that need clean books: legal fees, banker fees, due diligence expenses, and possibly a termination fee paid or received. Track deal spending in dedicated accounts from the day the process starts — if the deal closes, the buyer will ask for a schedule of transaction expenses, and if it falls apart, you need the number for your own planning. A plain-text ledger makes this trivial to audit later; the Beancount documentation covers account setup if you are starting from scratch.
A seller who pays outside counsel through signing and later pays a termination fee to accept a superior proposal might book it like this:

Assets:CheckingThe mirror image matters too: if you are the jilted first bidder and collect the fee, it is income, not a reduction of your deal expenses — book it to its own income account so your true transaction costs stay visible. Either way, keep deal accounts separate from operating expenses; a buyer, an auditor, or a future you will want transaction costs cleanly isolated from the cost of running the business.
The last useful step before you sign
Before you initial the deal-protection section of any sale agreement, answer four questions in writing: how long is the exclusivity, what exactly counts as a superior proposal, what does walking away cost at each stage, and how long does the first bidder get to match. If you can answer all four from the document in front of you — not from what someone told you it says — you understand your market check. If you cannot, that is your next call with your lawyer, and it is worth every billable minute.
