Founder profile →People search for a management buyout agreement expecting one document. There is no such document. A UK management buyout is recorded in a suite of eight to fifteen agreements, drafted by three or four sets of solicitors, negotiated in parallel over a few intense weeks, and signed on the same afternoon. The share purchase agreement is the one everybody names, but it is the facility agreement and the shareholders agreement that will govern the team's life for the next five years.
Understanding the suite matters commercially, not just legally. Each document allocates a specific risk between the vendor, the management team and the funders, and the team is the only party sitting on both sides of several of those allocations. This guide works through the documents in the order they are signed, what each one does, which clauses genuinely bite, and who negotiates what.
Heads of terms is a short document, usually five to ten pages, that records the agreed commercial shape of the deal before anyone spends money on drafting. It states the price and how it is structured, what is being bought, the conditions to completion, the intended timetable and who bears which costs.
Almost all of it is expressed as not legally binding, which leads teams to treat it casually. That is the mistake. In practice heads of terms set the anchor for every negotiation that follows: a price mechanism agreed loosely at this stage is very hard to reopen at draft two of the share purchase agreement, and a vendor who has read a heads of terms saying the consideration is payable in cash on completion will resist a vendor loan note six weeks later. Get the funding structure into the heads of terms explicitly, including the deferred element, the interest rate on it, and the fact that it will rank behind the senior debt.
A small number of provisions are binding and they are the ones to read carefully: confidentiality, exclusivity, costs, and any obligation on the team to cease looking at other opportunities. Those bind from signature.
Exclusivity, sometimes documented as a separate lock-out letter, is the vendor's promise not to negotiate with anyone else for an agreed period, typically eight to twelve weeks. It is the single most valuable protection a management team can extract at the heads of terms stage, because everything the team is about to spend is unrecoverable if the business is sold to someone else.
The asymmetry is stark. Once heads of terms are signed the team commissions legal drafting, the funder commissions financial due diligence, and both are paid for by the buyer whether the deal completes or not. Meanwhile the team is negotiating against its own employer, which limits how hard it can push on anything. Without exclusivity, a competing approach mid-process leaves the team having funded a data room for a rival bidder.
Two refinements are worth asking for. Extend the period automatically if the delay is caused by the vendor or by information that is late arriving, since funder due diligence stalls on vendor information more often than on anything else. And make the exclusivity period long enough to cover credit approval as well as legals, because a period that expires the week the funder goes to credit committee is not much of a protection.
The share purchase agreement, universally the SPA, is the contract by which the vendor sells the shares to newco. It is the longest document in the suite and it does five distinct jobs.
The consideration clause splits the price into cash on completion, any deferred consideration or loan note, any earn-out, and any retention held back against warranty claims. Each element needs its own mechanics: dates, interest, security and set-off rights. A vendor loan note is usually created by a separate loan note instrument and cross-referred here.
Where signing and completion are not simultaneous, the conditions sit here: funder drawdown, third-party consents, landlord consents on leases, change of control waivers on key customer contracts. Completion mechanics then set out the choreography of the day, which on an MBO involves the funder releasing money to the team's solicitor, the solicitor paying the vendor, and stock transfer forms and share certificates changing hands, all in a fixed order.
The bulk of the page count. Covered in the next section.
The vendor agrees not to compete, not to poach staff and not to solicit customers for a period after completion, typically two to three years. On an MBO these matter more than teams assume, especially where the vendor remains a minority shareholder or takes a consultancy role. A retiring owner with thirty years of customer relationships is the most dangerous competitor the business could have.
Either a tax covenant inside the SPA or, more commonly on deals of any size, a separate tax deed under which the vendor indemnifies the buyer for pre-completion tax liabilities. Because the vendor is realising a capital gain, capital gains tax at 18% or 24%, with Business Asset Disposal Relief at 18% on a £1 million lifetime limit from 6 April 2026, the vendor's own tax position shapes how they want the price structured. Source: HMRC. Our management buyout tax implications guide covers the interaction.
Warranties are statements of fact about the target company given by the vendor. If a warranty turns out to be untrue and the buyer suffers loss, the buyer has a damages claim. Indemnities go further: a pound-for-pound promise to reimburse a specific identified liability, used for known risks such as an ongoing employment tribunal or a contaminated site.
On a management buyout the warranty negotiation has a character all of its own, because the buyers work in the business. A vendor will argue, often fairly, that the finance director sitting across the table prepared the accounts being warranted. That argument produces three practical outcomes teams should expect.
The disclosure letter is where warranties meet reality. It is written by the vendor's solicitors and it qualifies the warranties by disclosing matters that would otherwise breach them, with a bundle of supporting documents attached. Anything properly disclosed cannot found a claim, which makes the letter as important as the warranties themselves. Read it as a risk register: it is the vendor telling you, on the record, everything they think might be wrong with the business.
Watch for general disclosure of everything in the data room and everything within the knowledge of the management buyers. Broad general disclosure on an MBO can hollow out the warranty protection almost completely, and it is negotiated rather than accepted.
An enterprise value agreed as a multiple of EBITDA has to be converted into a price for the shares, which means adjusting for cash, debt and whether working capital is at a normal level. Two mechanisms do that job and the choice has real consequences.
| Feature | Completion accounts | Locked box |
|---|---|---|
| When the balance sheet is measured | At completion, prepared afterwards | At a past date, already prepared and audited or reviewed |
| Price certainty at signing | Provisional, adjusted two to three months later | Fixed, plus interest on the equity value from the box date |
| Who carries trading risk before completion | The vendor | The buyer, from the box date |
| Post-completion work and dispute risk | Significant, an expert determination clause is standard | Minimal, no true-up |
| Typical fit on an MBO | Where the balance sheet is volatile or seasonal | Where the buyers produced the accounts and trust them |
MBOs lean towards a locked box more often than trade sales do, for the obvious reason: the buyers prepared the historical accounts and have no need for a post-completion audit of their own work. It also removes a fight the team does not want to have with a former boss two months after completion. What a locked box demands instead is leakage protection, a set of covenants stopping value leaving the company between the box date and completion, and those covenants deserve close reading if the vendor is still drawing dividends.
The shareholders agreement is the constitution of the newly owned company, signed by the management shareholders and any institutional investor, and read alongside new articles of association. The SPA governs one afternoon. This document governs the next five years.
Its core provisions are worth knowing before they are drafted around you:
Structural detail on how the layers of ownership fit together sits in our management buyout structure guide.
The facility agreement is the loan contract between the funder and newco. On a lower mid-market UK deal it is typically based on a bilateral form rather than a full syndicated document, but it carries the same architecture: the facilities and their purpose, drawdown conditions, interest and fees, repayment schedule, representations, covenants, events of default and the security to be granted.
Four parts of it decide how much freedom the team actually has after completion.
Usually a debt service cover ratio, a leverage covenant expressed as net debt to EBITDA, and sometimes an interest cover ratio and a capital expenditure limit. These are tested quarterly against management accounts and annually against audited figures. The headroom negotiated here, the difference between the covenant level and the forecast, is the most important number in the document. A 1.3 times cover covenant against a forecast of 1.35 times leaves no room for an ordinary bad quarter. Model it in the MBO debt capacity and DSCR calculator before agreeing the level.
The list of everything that must be delivered before money moves: signed security, board minutes, insurance, the completed independent legal advice certificates for every guarantor, evidence of the team's equity contribution. Late items here are the commonest cause of a completion date slipping by a week.
Restrictions on further borrowing, disposals, acquisitions, dividends and payments on the vendor loan note. That last one matters enormously: the facility agreement, not the loan note, usually determines whether the vendor can actually be paid on schedule.
What constitutes default, and whether the team has an equity cure right, the ability to fix a covenant breach by injecting cash rather than triggering enforcement. Cure rights are more commonly available on private equity backed deals where there is an investor able to write the cheque.
Security is granted by the borrower and its subsidiaries, and it is documented separately from the loan.
Three or four sets of solicitors are involved and the boundaries are not always obvious to a first-time buyer. The table below sets out the suite, what each document does and where the negotiation actually happens.
| Document | What it does | Who negotiates it |
|---|---|---|
| Non-disclosure agreement | Protects information shared before heads of terms | Vendor and management team |
| Heads of terms | Records the commercial deal, mostly non-binding | Vendor and management team, corporate finance adviser leads |
| Exclusivity or lock-out letter | Binding period in which the vendor cannot talk to others | Vendor and management team |
| Share purchase agreement | Sells the shares, sets the price, gives the warranties | Vendor solicitors and management team solicitors |
| Disclosure letter and bundle | Qualifies the warranties with disclosed facts | Drafted by vendor solicitors, scrutinised by the team |
| Tax deed or covenant | Indemnity for pre-completion tax liabilities | Tax advisers on both sides |
| Completion accounts or locked box schedule | Fixes the price for cash, debt and working capital | Accountants on both sides, lawyers document it |
| Vendor loan note instrument | Creates the deferred consideration as a debt instrument | Vendor solicitors, funder consents to the terms |
| Shareholders agreement and new articles | Governs control, information, leavers, drag, tag and exit | Management team, any investor, and their solicitors |
| Service agreements | Employment terms for the management shareholders | Management team and any investor |
| Facility agreement | The loan: facilities, covenants, defaults, drawdown | Funder solicitors draft, team solicitors negotiate |
| Debenture and share charge | Grants fixed and floating security to the funder | Funder solicitors, largely non-negotiable |
| Deed of priority or intercreditor | Ranks senior debt, asset based facilities and vendor debt | All funders plus the vendor |
| Personal guarantees and ILA certificates | Personal recourse against the team, with independent advice | Funder sets terms, each guarantor takes separate advice |
One practical consequence of that table: the team's corporate solicitors negotiate against two counterparties at once, the vendor and the funder, on different documents with different deadlines. Instructing a firm that has done buyouts before is worth more than a lower hourly rate, and the funder will in any event expect the team to be represented by a firm it recognises.
The order of work is what keeps a buyout on schedule. Agree the funding structure before the heads of terms are signed, because the heads set the anchor. Get exclusivity long enough to cover credit approval as well as drafting. Read the disclosure letter as a risk register rather than a formality. Negotiate covenant headroom rather than the interest rate, since headroom is what protects the business in a bad year. And book the independent legal advice appointments the day the offer is issued.

There is no single buyout agreement. A UK management buyout is documented by a suite, and the share purchase agreement is only the centrepiece. Expect heads of terms setting the commercial deal and an exclusivity period; a share purchase agreement carrying the price, the completion mechanics, the warranties and the limitations on them; a disclosure letter qualifying those warranties; a tax deed or covenant; a shareholders agreement and new articles governing how the team runs and eventually sells the company; and, on the funding side, a facility agreement, a debenture, a deed of priority and any vendor loan note instrument. A single document promising to cover all of that is a template, not an agreement.
Commercially, the managers who run a company buy it from its owner, usually through a new holding company funded by a mix of senior debt, asset based facilities, a vendor loan note, institutional equity and cash from the team. Legally, newco signs a share purchase agreement with the vendor, the funders sign a facility agreement with newco, security is granted by debenture over the trading company, and the shares transfer at completion against payment of the day-one consideration. Our guide to how a management buyout works sets out the sequence, and the process guide covers the four to nine month timeline.
The vendor gives the warranties, as in any share sale, but the position is materially complicated by the fact that the buyers already run the business. A vendor who has been at arm's length from operations for years will argue that the management team knows the trading position better than they do, and will push for a narrow warranty set, tight caps and a general disclosure of everything within the buyers' knowledge. Management often gives its own warranties too, to the funders rather than to the vendor, confirming the accuracy of the business plan and forecasts in the facility agreement. That is where a careless forecast becomes a legal problem.
Both fix the price for cash, debt and working capital, but at different dates. Completion accounts value the balance sheet at completion, so the price is provisional on the day and adjusted once accounts are prepared and agreed two or three months later. A locked box fixes the price by reference to a historical balance sheet already prepared, so the economic risk passes to the buyer from that earlier date and the price is certain at signing, usually with a daily interest charge on the equity value for the intervening period. Locked box gives certainty and speed, completion accounts give accuracy, and on MBOs a locked box is often preferred because the buyers already trust the numbers they produce themselves.
A leveraged buyout is defined by how it is funded; a management buyout is defined by who buys. An LBO is any acquisition where debt provides most of the price, whoever the buyer is, and is usually driven by a private equity house. An MBO is an acquisition led by the incumbent management team, and because teams rarely have the cash, most MBOs are also leveraged. The documents overlap almost entirely, though an LBO run by an institutional sponsor typically carries heavier covenants, a longer intercreditor agreement and more prescriptive governance. Our MBO versus LBO guide compares the two.
Each side pays its own advisers, and the company usually ends up funding a large share of it. Newco pays for the team's corporate solicitors, the funders' legal fees and the financial and legal due diligence the funder commissions, all of which sit in the sources and uses table as transaction costs. The vendor pays their own solicitors and tax advisers. Budget for the total to be a meaningful percentage of a lower mid-market deal, and make sure the funding raised includes it, because a structure that funds the price and forgets the fees is short on day one.
On a straightforward UK lower mid-market MBO, four to eight weeks from heads of terms to completion is realistic where due diligence has already started and the funding is credit-approved. The share purchase agreement, facility agreement and shareholders agreement are negotiated in parallel rather than in sequence, which is what makes the compression possible. Deals slip for three predictable reasons: due diligence surfaces something the disclosure letter has to deal with, the security package needs a deed of priority nobody scheduled, or the personal guarantee independent legal advice appointments are booked too late.
