When a Supply Contract's Exit Clause Finally Got Tested

The situation

Keisha and Simone had inherited their parents' Tillsonburg manufacturing company a few years earlier, a business that made custom packaging components for mid-size industrial customers, with annual revenue in the tens of millions. Neither sister worked in the business full time. Keisha managed a portfolio of commercial rental properties and Simone ran her own dental practice, but both sat on the company's board and had final say on anything that mattered, including the contracts their operations manager negotiated on the company's behalf.

Three years earlier, the company had signed a five-year supply agreement with a manufacturer that used its components as a subassembly in its own products. The agreement locked in fixed pricing for the full term in exchange for a minimum annual purchase volume from the customer, a trade-off that made sense for a company committing plant capacity and raw material contracts years in advance. The relationship had been steady until raw material and freight costs rose sharply, squeezing the customer's margins on a fixed price it had agreed to when input costs were much lower.

The problem

The customer's operations lead, Rejean, sent formal notice that the customer was terminating the agreement immediately, citing a batch of components delivered several months earlier that had failed a dimensional tolerance check. The batch had been remade at the company's cost after the original complaint, and no further issue had been raised since. Rejean's letter treated that old, already-resolved defect as grounds for termination for cause, which under the agreement allowed immediate termination without further payment obligations if the supplier failed to cure a material breach within a stated period.

Termination for cause and termination for convenience are different mechanisms in a supply agreement, and the difference is usually where the money is. A termination for cause, if it holds up, typically lets the terminating party walk away without paying for the remaining committed volume and without compensating the other side for costs incurred in reliance on the contract. A termination for convenience clause, by contrast, usually requires notice and some form of compensation, precisely because it lets a party leave a deal that is no longer convenient for it rather than because the other side did something wrong.

Keisha and Simone's operations manager had signed off on remaking the defective batch at the time without escalating it to the board, and the correspondence around that episode did not clearly establish that the issue had been treated as resolved and closed by both sides. That gap mattered once the same episode was recast, months later, as an unresolved material breach.

What we did

1. Read the termination clause against the correspondence file, not against either side's memory of events. The agreement defined a material breach as one that was not cured within a stated period after written notice, and it required that notice to specifically identify the breach and the cure required. No such notice had ever been sent for the tolerance issue; the company had simply remade the batch as a customer service matter, without either side invoking the contract's breach and cure process. That gap was the strongest fact in the case: a termination for cause generally cannot rest on a breach that was never formally noticed and never given a chance to be cured, because the clause's own procedure was not followed.
2. Assessed what a termination for convenience would actually cost the customer. The agreement's convenience clause, buried further down than the cause clause, required a defined notice period and payment for tooling and dedicated equipment the company had purchased specifically to serve this customer's specifications. We calculated that exposure, which ran to a meaningful six-figure sum once the remaining minimum volume commitments and unamortized tooling costs were added together, and used it as the anchor for negotiation rather than the customer's preferred narrative of a for-cause exit at no cost.
3. Sent a response that named the mechanism, not just the disagreement. Rather than simply disputing that a breach had occurred, the response set out why the termination for cause notice was procedurally defective under the agreement's own terms, and stated plainly that the company would treat any unilateral exit as a termination for convenience triggering the associated payment obligations, or as a breach of the agreement by the customer if it simply stopped placing orders.
4. Opened a negotiation once the legal footing was clear. Once it was apparent that a clean, cost-free exit for cause was not available to the customer, both sides had a reason to talk. The company did not want years of litigation with a long-standing customer, and the customer did not want to pay the full convenience termination cost on top of admitting there had been no valid cause. We negotiated from that shared incentive rather than treating the dispute as a fight to be won outright.
5. Documented the compromise as a formal amendment, not a side letter. The final terms were written into an amending agreement that superseded the original termination language for the remainder of the relationship, closing off any ambiguity about which version of events governed if a dispute arose again before the wind-down was complete.

The outcome

The parties settled on a phased wind-down rather than either an immediate exit or the full remaining term. The customer agreed to continue purchasing at a reduced but still meaningful volume for about eighteen months, roughly half of what remained on the original five-year term, after which the agreement would end without further obligation on either side. In exchange for the shortened term, the customer paid the company a partial contribution toward the unamortized tooling costs, covering a substantial share of that expense rather than the full amount the convenience clause would have required over the original timeline.

Neither side got everything it wanted. The company lost roughly half of the contracted revenue it had planned its capacity around, and had to find other customers to fill that capacity earlier than expected. The customer paid more than the cost-free exit it had originally claimed, and had to keep buying at fixed pricing for a further eighteen months despite the input cost pressure that had prompted the dispute in the first place. Both sides avoided a drawn-out commercial dispute in the Superior Court, where the outcome would have turned heavily on how a judge read the same notice-and-cure language, with legal costs on both sides likely exceeding what the compromise cost either party.

For Keisha and Simone, the practical lesson landed closer to home than the contract dispute itself. Their operations manager's decision to quietly remake a defective batch, made with good intentions and without any bad faith, had left the file without the paper trail that would have shut down the customer's termination claim immediately rather than after weeks of negotiation.
