What is an Exclusivity Period?

You have pitched your company for months. You finally receive a Term Sheet or a Letter of Intent. Inside that document there is a specific clause that changes the dynamic of your entire negotiation. This is the exclusivity period.

An exclusivity period is a defined timeframe during which a seller or founder agrees not to solicit, entertain, or negotiate offers from other potential buyers or investors. It is often referred to in legal circles as a no-shop clause.

The clock starts ticking the moment you sign the document. For the duration of this period you are effectively taken off the market. You cannot use this offer to create a bidding war with other investors. You must focus solely on closing the deal with the party sitting across the table.

It is vital to understand why this clause exists. Investors and acquirers are about to spend significant money on due diligence. They will hire lawyers, accountants, and technical experts to audit your business. They do not want to incur these costs if you are simply using their offer as a stalking horse to get a better price from someone else.

However, this creates a distinct shift in power. Before you sign, you have the leverage because you can walk away to a competitor. After you sign, the investor has the leverage.

They know you cannot go elsewhere. They also know that time is usually working against a startup. You are burning cash every day the deal does not close. If they drag their feet, your desperation might increase, which could lead to renegotiated terms that are less favorable to you.

Founders often confuse which parts of a Term Sheet are legally enforceable.

Most components of a Term Sheet are non-binding. The valuation, the investment amount, and the board seat composition are usually expressions of intent. If the investor wakes up tomorrow and decides not to invest based on those terms, they can usually walk away without legal penalty.

The exclusivity period is different. It is almost always a legally binding provision. If you sign the sheet and then secretly negotiate with another firm during the exclusivity window, you can be sued for breach of contract.

This distinction is critical. You are committing to a legal restriction in exchange for a non-binding promise to attempt to finalize a deal.

There are two main environments where you will face this constraint.

Venture Capital Funding In a Series A or B round, investors will typically ask for 30 to 45 days of exclusivity. This allows them to verify your metrics and customer contracts. If an investor asks for 60 or 90 days, you should ask why they need that much time. Long exclusivity periods can run a startup out of runway if the deal collapses.

Mergers and Acquisitions In M&A, the stakes are higher. The diligence is more invasive. Buyers may request 45 to 60 days. In this scenario, the risk of a broken deal is severe. If the market learns you were in talks to be acquired and the deal failed, it can signal that there is something wrong with your business.

When reviewing these terms, you must ask yourself a few questions.

Do I have enough cash to survive if this deal falls through after 45 days?

Is the investor asking for automatic renewal of the period?

Can I carve out exceptions for parties I am already in deep talks with?

Understanding the weight of this clause ensures you do not lock your company into a waiting game it cannot afford to lose.
