The Architecture of a Business Sale: LOI vs. OREA APS vs. SPA

When you are selling a business, the document you choose to initiate the transaction is not just paperwork; it is a tactical decision that determines your leverage, your legal exposure, and the speed of your exit.

In Ontario, we often see a “tug-of-war” between three different vehicles: the Letter of Intent (LOI), the OREA Agreement of Purchase and Sale (APS), and the Share Purchase Agreement (SPA). Understanding when to use which is the difference between a smooth transition and a deal that falls apart after months of wasted effort.

1. The Letter of Intent (LOI): The “Open-Book” Approach

The LOI serves as a preliminary expression of interest. While it is a common starting point, it is important to understand the strategic implication for a seller: choosing this route is a decision to grant a prospective buyer access to your internal financials and operations before they have made a financial commitment via a deposit. 

In practice, most LOIs are ineffective at setting the foundation for the final deal because they rarely address the granular, deal-making terms—such as holdbacks, working capital adjustments, or specific asset exclusions. Beyond the intended purchase price and the exclusivity period, the substantive terms remain unnegotiated, leaving significant gaps that will inevitably arise later.

This leads to two major drawbacks for the seller:

• The Inefficiency Trap: Because only the high-level points are agreed upon, you essentially enter a “dead period.” You are forced to wait until the end of the due diligence process to see if the buyer will agree to the actual terms that matter, such as payment structures or legal protections. If you reach an impasse on these later, you have wasted weeks or months of exclusivity.  
• The Exclusivity Lock: By signing an LOI with an exclusivity (“no-shop”) clause, you are effectively locking your business away. You cannot entertain other offers or even engage in meaningful discussions with other potential buyers while this party performs their review.

From a seller’s perspective, this is a strategic trade-off. It can be a practical path if the business is underperforming or requires a turnaround, where you have limited leverage and are motivated to provide a “look under the hood” to attract a buyer willing to take on that risk. However, you must be comfortable with the fact that you are providing this transparency without the buyer having any “skin in the game” via a deposit.

2. The OREA Agreement of Purchase and Sale (APS): The “Binding Blueprint”

Often introduced by real estate professionals, the OREA APS transforms a speculative negotiation into a structured, binding commitment.

Unlike an LOI, the OREA APS creates a binding contract from the outset. Crucially, it mandates a deposit. While this deposit is typically refundable if the buyer fails to satisfy conditions such as due diligence or financing, the act of placing funds in trust acts as a necessary filter for serious intent. Furthermore, the presence of a deposit incentivizes the buyer to complete due diligence in a timely, disciplined manner, as opposed to the open-ended, slow-paced review often seen when no deposit is involved.

The “Pre-Negotiation” Philosophy:

The primary utility of the OREA APS lies in the ability to pre-negotiate “deal-breakers” before the heavy legal lifting begins. A well-structured OREA APS establishes a concrete, actionable timeline. While timelines remain negotiable based on the complexity of the transaction, once set, they ensure all parties adhere to a specific roadmap. For instance, a structure mandating 30 days for due diligence, 30 days to finalize the Share Purchase Agreement, and 30 days to closing creates a transparent schedule that keeps both the buyer and seller accountable.

Eliminating Ambiguity:

By negotiating critical terms – such as working capital adjustments, non-compete clauses, and holdbacks – within the OREA form, the parties avoid the “lock-in trap”. In an LOI-driven process, the buyer and seller often enter an exclusivity period without having reached an agreement on these fundamental mechanics. This leaves the seller in a “dark period,” potentially tied to a buyer who may not share the same vision for the deal.  On the other hand, the OREA APS approach ensures that if a buyer demands a 20% holdback that the seller finds unacceptable, this fundamental issue is resolved at the start rather than after the due diligence phase. This disciplined approach prevents both buyer and seller from burning through significant legal fees on an SPA that was never destined to be signed.

3. The Share Purchase Agreement (SPA): The “Final Authority”

The SPA serves as the definitive legal document governing the transaction. It is the repository for the “Representations and Warranties” (R&Ws) – the binding clauses where the seller legally affirms the accuracy of the financials, the compliance of tax obligations, and the proper classification of employees.

The Efficient Sequence: A frequent misstep in transaction structuring is initiating the process directly with the SPA negotiation. As the SPA is a comprehensive document heavily laden with complex legal mechanics, attempting to draft it while simultaneously negotiating foundational commercial terms (such as purchase price, net working capital, training, payment schedules, or holdbacks) results in a highly inefficient use of time and capital.

The “Formalization” Approach: The most strategic path is to leverage the OREA APS to secure the commercial deal points first. Under this workflow, the SPA is only drafted after the buyer has successfully completed due diligence and secured financing. At this advanced stage, the SPA functions merely as a legal “translation” of the terms already ratified in the APS. Treating the SPA as a formalization of a pre-existing agreement – rather than a primary negotiation tool – drastically reduces legal back-and-forth, minimizes advisory fees for both the buyer and the seller, and keeps the closing timeline strictly on schedule.
