The purchase agreement, clause by clause

A business purchase agreement is built from a consistent set of parts regardless of the deal’s size — the parties and what’s being sold, the purchase price and how it can be adjusted, conditions that must be met before closing, representations and warranties about the business, covenants governing conduct before and after closing, indemnification for what goes wrong, and the mechanics of closing itself.

Reviewed

A business purchase agreement can run to dozens of pages, and to a first-time buyer or seller it can read like an undifferentiated wall of legal language. It isn’t. Every agreement, however long, is built from a fairly consistent set of components, each doing a specific job, and once you know what each section is actually for, the document stops being intimidating and starts being something you can negotiate intelligently, clause by clause, instead of accepting wholesale.

Parties, recitals and what’s actually being sold

The opening sections identify who’s buying, who’s selling, and precisely what’s changing hands, whether that’s the shares of a corporation or a defined list of assets and assumed liabilities. This section sounds like boilerplate, but it’s where the fundamental structure of the deal, asset sale or share sale, gets locked into the document, and where any related entities, like a separate holding company retaining certain assets, get named explicitly rather than left to assumption.

Purchase price and how it can move

Beyond the headline number, this section sets out how the price is actually calculated and paid, cash at closing, any vendor take-back or holdback, and, often, a mechanism for adjusting the final price based on the business’s working capital or net assets measured as of the closing date rather than as of whenever the deal was first negotiated. This adjustment mechanism matters more than it looks like on a first read, since it’s frequently the source of a post-closing dispute if it isn’t drafted precisely. Buyers and sellers who agree on exactly how that calculation works, and who resolves a disagreement over it, early in negotiations, rather than leaving the mechanics vague, avoid one of the more common and most avoidable disputes that surfaces after closing.

Conditions precedent: what has to happen before closing

This section lists the things that must occur, or be confirmed, before either side is obligated to close, financing being secured, a landlord’s consent to assign a lease, third-party contract consents, due diligence being satisfactory, and, particularly on larger deals, a clause confirming nothing has materially harmed the business between signing and closing. Conditions give both sides an orderly way to walk away, or renegotiate, if something material doesn’t come together, rather than being forced to close on a deal that’s changed in some important way since it was first agreed.

Representations, warranties and covenants

Representations and warranties are the seller’s statements of fact about the business, that the financial statements are accurate, that there’s no undisclosed litigation, that the business owns what it claims to own, and covenants are promises about conduct, both before closing, like running the business normally and not making major changes, and after, like a non-compete. These sections carry real legal weight and deserve their own careful review, which is why they’re covered in depth in a dedicated guide rather than compressed into a paragraph here.

Indemnification and disclosure schedules

Indemnification sets out what happens if a representation turns out to be false, or a covenant is breached, who pays, how much, and within what limits, and it works hand in hand with disclosure schedules, where the seller lists specific exceptions to the representations being made. A representation that the business has no pending litigation, qualified by a disclosure schedule listing one specific claim, is a very different, and more honest, statement than the same representation made with no schedule at all.

Non-competition and other restrictive covenants

Many purchase agreements include a covenant restricting the seller from competing with the business, soliciting its customers or employees, or using its confidential information for a period after closing. These restrictive covenants protect the goodwill the buyer is paying for — a buyer who pays for customer relationships and then watches the seller open a competing business next door, drawing on those same relationships, hasn’t really received what it paid for. How broad and how long a restrictive covenant can reasonably be, and how enforceable it actually is if challenged, depends heavily on the specific facts and on the province, which is why this clause needs careful, individualized drafting rather than a boilerplate paragraph copied from an unrelated deal.

Closing mechanics and what follows

The final sections set out exactly how closing actually happens, what documents get delivered, how funds move, and what deliverables each side owes the other on the day itself, along with anything that survives closing, like ongoing covenants, indemnification obligations, or a transition period the seller has agreed to. This is mechanical in a literal sense, and getting it wrong causes real delays, which is why it also gets its own dedicated treatment.
