When distribution agreements go awry: lessons from Westbase Technology Ltd v Vuzix Corporation

Distribution agreements are a key part of supply chains. These agreements seek to define roles, protect commercial interests, and allocate risk. Yet even well-drafted agreements can give rise to disputes, particularly where minimum purchase requirements, contract variation, and cross-border issues intersect in ways that challenge commercial expectations. The recent High Court judgment in Westbase Technology Ltd v Vuzix Corporation offers important insights for both suppliers and distributors.

The agreement

At the heart of the dispute was a written distribution agreement dated 15 June 2022, under which Westbase Technology Limited agreed to act as a distributor for Vuzix’s extended reality “smart glasses” and related products.

The agreement imposed a “minimum business volume” obligation - effectively a minimum purchase requirement - of US$1.3 million annually, measured by the amount paid to Vuzix. The agreement was intended to run for an initial three-year term, automatically renewing for further one-year periods unless terminated by notice.

Alongside the minimum business volume obligation, the agreement contained a suite of standard contractual provisions that would later prove central to the conflict — most notably, a choice of governing law and exclusive venue clause selecting the law of the State of New York and providing for the New York courts to exclusively determine disputes (unless Vuzix opted for another suitable forum). In addition there was an entire agreement clause and a formal amendment / waiver clause providing that any modification to the distribution agreement would be effective only if recorded in a signed writing.

In the Westbase case, the distributor achieved only about US$270,000 in sales in its first year — a small part of the US$1.3 million requirement.

Shortfall

Westbase achieved only about US$270,000 in sales in its first year — a small part of the US$1.3 million requirement.

This shortfall in performance was the precursor to escalating tensions between Westbase and Vuzix.

For Westbase, the failure to achieve the minimum volume crystallised the commercial disconnect between what was anticipated and what was realised in practice. It also raised questions about whether the distributor could meet its obligations over the life of the agreement without accumulating substantial unsold inventory. For Vuzix, the minimum volume clause provided a contractual basis to invoke termination rights when it became apparent that Westbase was not fulfilling its commercial commitments.

Minimum purchase requirements

Suppliers often insist on a minimum purchase requirement when appointing distributors. From a supplier’s perspective, such a clause serves to underpin forecast sales, incentivise the distributor to prioritise the supplier’s products, and justifies exclusive or preferential treatment within territories.

Distributors accept the obligation in exchange for territorial rights, pricing terms, marketing support, and exclusivity. But for distributors such clauses can become burdensome where market uptake fails to reach expectations, where the distributor’s understanding of demand is overly optimistic, or where external factors (economic cycles, competitive pressures) depress actual sales.

As such disputes over minimum purchase requirements resonate in supplier-distributor relationships because they bring to the fore differing commercial incentives.

When sales disappoint, the supplier may perceive that it is carrying undue risk, and the distributor may feel trapped by commitments it cannot honour without suffering losses on unsold stock. In Westbase, this dynamic was exacerbated by additional proprietary obligations and exclusivity provisions in the written agreement, which Westbase alleged were breached by Vuzix.

Negotiations

It was in this context that the parties turned, late in 2023 and early in 2024, to negotiations aimed at resolving their differences. Westbase claimed that a series of telephone calls between representatives of Westbase and those of Vuzix in December 2023 and January 2024 culminated in an oral resolution. The essence of that purported oral agreement was that Vuzix would buy back unsold stock from Westbase in five tranches over a year, at the original sale price. Westbase asserted that this arrangement was intended to be a legally binding contract that “replaced” the written distribution agreement in its entirety, effectively cancelling the original agreement and substituting the oral contract with its own governing terms — including, implicitly, a new set of rights and obligations unconstrained by the written agreement’s choice of law, court venue, or other formalities.

Vuzix took the opposing position. It contended that the telephone discussions expressly included terms indicating that the parties did not intend to create legal relations, that there was no meeting of minds sufficient to form a binding contract, and even if certain repurchase obligations arose, those obligations did not cancel or vary the distribution agreement itself. In other words, the written agreement remained the operative contract between the parties, including its governing law and court venue provisions.

When can it be said that the parties have agreed to vary?

The tension between the written agreement and alleged oral modifications highlights a perennial problem in commercial contracting: when, if at all, can parties be taken to have varied or supplanted their governing agreement outside the formal amendment procedures the agreement itself prescribes?

Many distribution agreements, such as the one in Westbase, include entire agreement clauses that declare the written document to contain the “sole and entire understanding” between the parties. They also include amendment clauses that require any modification to be in a signed writing. These clauses are intended to promote certainty and to guard against precisely the type of post-contractual informal arrangements that Westbase claimed had been reached.

For suppliers, the lessons from this are stark. If you wish to prevent the possibility of ad hoc, informal variations to a key commercial agreement, you must ensure that the contract’s formalities — including the requirement for signed written amendments — are both clear and enforceable. You should also be prepared to reinforce those formalities in practice; for example, by responding in writing to any informal proposals for variation that come up in negotiation, and ensuring that any agreed modifications are documented in a formal amendment before they are implemented.

For distributors, there are equally important lessons. Distributors often operate under considerable commercial pressure once they enter into a contract with minimum purchase commitments and exclusivity. When performance does not meet expectations, distributors may seek to re-negotiate terms or agree informal accommodations with suppliers. The Westbase decision underscores that, absent strict compliance with the formal modification procedures in the contract, distributors may find themselves unable to rely on such accommodations if they later seek to enforce them. An oral understanding, however commercially practical it seemed at the time, may prove legally ineffective if the original agreement requires formal amendments.

What law and where?

Underlying these substantive disagreements was the question of where any dispute ought to be resolved and under what law.

The written distribution agreement selected the law of New York and exclusive New York court venue (jurisdiction) for “any claim related to this Agreement,” while also permitting Vuzix, at its option, to elect another competent forum - in other words, another court or arbitration.

Once Westbase alleged that the distribution agreement was entirely supplanted by an oral agreement, it implicitly challenged the continuing relevance of the governing law and court venue clause.

If the oral contract was the true agreement between the parties, Westbase argued, then a different governing law (perhaps English or Dutch law) might apply, and the English courts might hear the dispute - and it is very likely that Westbase was advised that this would be to its advantage I respect of arguing that the written distribution agreement had been replaced.

As a result Westbase commenced a claim in the High Court against Vuzix. But given Vuzix’s location it was necessary to obtain the permission of the High Court to serve the claim form on Vuzix “out of the jurisdiction”.

Westbase was successful in obtaining permission and it was to try and reverse the granting of  permission that there was a hearing and eventually a decision by the Court.

For suppliers doing business with international partners, this aspect of the case should serve as a cautionary reminder that choice of law and jurisdiction clauses are among the most significant elements of any cross-border contract and should be carefully drafted if they are to be relied upon.
