What is a heads of agreement?

A heads of agreement is a short summary of the main commercial terms of a deal, signed before lawyers draft the full contract. It fixes price, structure, timing and conditions in a page or two, so the long document is written from an agreed base rather than negotiated from scratch.

In Australia and the United Kingdom this is the document that stops a transaction dying in the drafting. It exists because agreeing the shape of a deal and agreeing its two hundred clauses are different jobs, and doing them at once takes twice as long.

What belongs on the page

Keep it to the terms that would make somebody walk away. The parties, named as the legal entities that will actually contract. What is being bought or done, described precisely enough that nobody can substitute something cheaper. The price, and if the price moves, the mechanism that moves it. The conditions that must be satisfied before completion, such as finance, a landlord's consent to assign a lease, a licence transfer or a satisfactory inspection. The timetable, with a date for the long form document and a date for completion. And any restraint, retention or earn out, because those are the provisions most likely to blow up later and the ones a seller least expects. Everything else, indemnities, warranties, boilerplate, belongs in the contract and only slows this document down.

The binding core

A heads of agreement is a statement of intention with a small hard centre. Confidentiality protects what each side sees during due diligence, and matters most to the seller, whose customer list and margins are about to be opened up. Exclusivity stops the seller running a parallel process while the buyer spends money on advisers, and it should carry a stated end date rather than a period counted from a vague event. A costs clause says who pays if talks collapse, which is usually each their own. Governing law and jurisdiction round it out. State in one clause which numbered paragraphs bind, and put those paragraphs together so a reader can see the boundary at a glance rather than inferring it from tone.

Why it is worth the two days it takes

Long form drafting is expensive and slow, and the expensive slow part is discovering that the parties never agreed on something fundamental. A seller who assumed stock was included, a buyer who assumed the lease transfers automatically, a founder who assumed the restraint applied only to the same suburb: each of those surfaces in week five of drafting, when both sides have already spent money and neither wants to be the one who walks. Bringing the disagreement forward to week one, onto a page short enough that everybody actually reads it, is the whole return. The document also gives advisers a brief, which is the difference between a first draft that needs comment and a first draft that needs rewriting.

Where these documents go wrong

Precision creep is the usual failure. A page grows into eleven, acquires operational detail, and starts to look enforceable, at which point the parties are negotiating the contract twice. The opposite failure is vagueness dressed as flexibility, where price is described as around, timing as promptly and scope as to be agreed, leaving a document that records nothing anybody can rely on. Between them sits the exclusivity clause with no end date, which quietly runs forever, and the version that never says which paragraphs bind. Each of these is a drafting decision made in an hour that costs weeks later, and each is visible on a careful read before anybody signs.

Handing over to the real contract

Say expressly what happens to this document when the long form agreement is executed: that it ceases to have effect, except for the clauses expressed to survive, and name them. Without that sentence, two documents describing the same transaction sit in the file, and in a dispute each side quotes whichever one helps. It is also worth naming who drafts the long form, since the party holding the pen sets the starting position on everything the summary did not cover, and that advantage is worth more than most of the points argued over in the summary itself. One last practical point: circulate the summary to the people who will run the business afterwards, not only to the people negotiating it. An operations manager reads a stock count method differently from a corporate adviser, and the objection worth hearing usually comes from whoever has to do the counting on the day of completion.

Questions people ask

Is a heads of agreement the same as a term sheet?

Close enough that the choice is regional habit. Heads of agreement and heads of terms are the Australian and British phrasings, and term sheet is the American one that has followed venture funding everywhere. The content and the binding carve outs are the same. Where they differ is format, since a term sheet is often a table of headings and a heads of agreement usually reads as short prose.

Who prepares it, the buyer or the seller?

Usually the buyer, because the buyer is the one proposing terms and wants them recorded in their own words. A seller running a competitive process sometimes issues a template instead, which keeps every bidder on comparable terms and is a considerable advantage. Whoever drafts it sets the anchor, so a party who cedes the pen should read what comes back very carefully.

Can a party walk away after signing one?

Yes, on the non binding parts, and that is the point of the form. What they cannot walk away from is confidentiality, any costs undertaking, and exclusivity for the period it runs. Walking away also has a commercial cost that no clause captures, since the market notices, and in small industries the market is a dozen people.

Should it mention due diligence?

It should say how long due diligence runs, what access will be given and what happens if it turns something up. The last part is the useful one: a right to renegotiate, a right to walk, or a price adjustment mechanism. A document that grants sixty days of access without saying what a bad finding entitles the buyer to do has recorded a courtesy rather than a right.

Does it need to be witnessed?

No, not unless it is being executed as a deed, which would be unusual for a summary of this kind. Ordinary signature by an authorised person for each party is sufficient. Where the binding clauses matter a great deal and there is doubt about consideration, some parties execute a short separate confidentiality and exclusivity deed alongside it.

How long should it stay open before it lapses?

Give it an expiry, typically the same date as the exclusivity period, and say that the document lapses unless extended in writing. An open ended summary sitting in a file is a nuisance, because a party who lost interest six months ago can point to it as evidence of what was agreed if circumstances change in their favour.
