The key provisions in long-term agreements are the clauses that keep a multi-year deal workable when prices move, performance slips, ownership changes, or something nobody planned for disrupts the relationship. At minimum, a contract running beyond one year needs to be in writing and should address price adjustment, performance standards, renewal, termination and exit costs, force majeure, assignment, dispute resolution, and how amendments get made. Each of these solves a problem that a shorter contract can afford to ignore.
Put It in Writing
Any contract that cannot possibly be completed within one year from the date it is made falls under the Statute of Frauds, which requires the agreement to be written down and signed by the party you would want to enforce it against.1Legal Information Institute. Statute of Frauds Without a signed writing containing the key terms, a court can refuse to enforce the deal at all.
Courts look at whether completion within a year is theoretically impossible, not whether it is unlikely. A three-year services contract cannot by its own terms wrap up in twelve months, so it must be written. The Statute of Frauds is an affirmative defense, meaning the other side has to raise it, but relying on an opponent’s oversight is not a strategy. For any agreement stretching beyond a year, put it on paper.
Price Escalation Clauses
A fixed price that looks fair today can become punishing three or four years in. Escalation clauses tie pricing to an external benchmark, most commonly the Consumer Price Index published by the Bureau of Labor Statistics.2Bureau of Labor Statistics. How to Use the CPI for Contract Escalation Federal procurement contracts use similar mechanisms, selecting a CPI variant or other broad-based index tracking the relevant industry’s cost movements.3Acquisition.gov. 852.216-71 Economic Price Adjustment of Contract Price(s) Based on a Price Index
Pair the escalator with a cap and often a floor. A cap limits the annual increase to a set percentage, keeping cost growth predictable for the buyer. A floor guarantees the provider a minimum adjustment even if the index drops.2Bureau of Labor Statistics. How to Use the CPI for Contract Escalation Caps in the 3% to 5% range are common in commercial service contracts. Without a cap, a provider can pass through the full effect of a high-inflation year. Without a floor, the provider absorbs the hit during deflationary periods. Negotiate both upfront.
Performance Standards and Service Levels
Price mechanics don’t tell you whether the other side is actually performing. Service-level provisions do. Define specific, measurable targets: uptime percentages for technology providers, production volumes for manufacturers, response times for service teams. Vague language like “best efforts” invites arguments. “99.5% system availability measured monthly” does not.
Spell out what happens when targets are missed. Graduated consequences work better than an all-or-nothing approach. A small shortfall might trigger a service credit on the next invoice. Repeated failures might allow the non-breaching party to withhold a percentage of payment or trigger a formal review. Monthly dashboards or quarterly reviews keep both sides honest and create a paper trail that matters if things eventually go sideways.
Renewal Mechanisms
When the term ends, what happens next depends entirely on how the renewal clause is drafted.
An evergreen clause automatically renews the deal for another period of the same length unless one side sends written notice before a specified deadline. A typical provision renews the agreement for another term unless either party gives written notice of non-renewal at least 30 days before expiration. Many states have consumer protection laws requiring sellers to remind buyers about upcoming automatic renewals, with notice windows commonly running between 30 and 60 days before the cancellation deadline.
The danger with evergreen clauses is forgetting the opt-out window. Miss the notice deadline by a single day and you could be locked in for another full term. Calendar the deadline with multiple reminders well in advance.
An option to renew works differently. It requires the party who wants to continue to say so affirmatively in writing before the deadline. Silence means the contract expires. That shifts the default from “we’re locked in” to “we’re done unless someone acts.”
A right of first refusal gives one party the chance to match any competing offer before the other side can sign with someone else. The party receiving a third-party offer must send written notice specifying the price and terms, and the right-holder gets a set window to decide whether to match.4U.S. Securities and Exchange Commission. Right of First Refusal Agreement It is common in commercial leases and joint ventures where one party has a strategic interest in blocking outside competitors.
Termination and Exit Costs
Not every multi-year relationship survives its full term. The contract should set the rules for ending early.
Termination for Cause
Termination for cause lets you end the contract when the other side has committed a serious breach: failing to deliver, missing payments, or violating a core obligation. The contract should define what counts as a breach serious enough to justify termination and distinguish it from minor hiccups. Most agreements include a cure period, typically 15 to 30 days, giving the breaching party a chance to fix the problem before termination becomes final. If the breach is cured within the window, the contract continues as if nothing happened.
Termination for Convenience
A termination for convenience clause lets a party walk away without pointing to any specific failure by the other side. In federal government contracts, this is a standard provision allowing the government to end a deal whenever it determines termination is in the public interest, with the contractor entitled to recover costs incurred plus a reasonable profit on completed work.5Acquisition.gov. FAR 52.249-2 Termination for Convenience of the Government (Fixed-Price) In private contracts, the same concept appears with a required notice period, often 90 to 180 days, and some form of payment to the other side for the lost deal.
Liquidated Damages vs. Penalties
Walking away from a five-year contract in year two means three years of expected revenue just evaporated for the other side. Contracts handle this through early termination fees or liquidated damages clauses, and the distinction matters.
A liquidated damages clause sets a predetermined amount the terminating party will pay. Courts enforce these when two conditions are met: the actual harm from early termination would be difficult to calculate at the time the contract was signed, and the amount specified is a reasonable estimate of the likely loss. Charging 50% of the remaining contract value might survive scrutiny if the non-breaching party can show lost revenue, redeployment costs, and idle capacity would roughly equal that figure.
Charging 100% of the remaining value when actual losses would clearly be far lower starts looking like a penalty. Courts in the U.S. generally refuse to enforce penalty clauses. If a judge concludes the amount is grossly out of proportion to the anticipated loss, the clause gets struck down and the non-breaching party is left trying to prove actual damages.
Force Majeure
Long-term agreements are uniquely vulnerable to events nobody saw coming. A force majeure clause excuses performance when extraordinary circumstances make it impossible or impractical to fulfill the contract. These clauses typically list covered events: natural disasters, war, government orders, epidemics, labor strikes, and infrastructure failures. Modern contracts often add cyberattacks, sanctions, and supply chain disruptions. The more specific the list, the better. Courts read force majeure clauses narrowly, so an event that isn’t listed or doesn’t clearly fall within a catch-all may not be covered.
Even without a force majeure clause, the Uniform Commercial Code provides a backstop for sale-of-goods contracts. Under the impracticability doctrine, a seller is excused from delivery when performance has been made impracticable by an event that neither party assumed would happen when the contract was signed, or by compliance with a government regulation.6Legal Information Institute. UCC 2-615 Excuse by Failure of Presupposed Conditions The bar is high. A price increase alone, even a steep one, rarely qualifies. And the seller still has to notify the buyer promptly about any delay or shortfall.
Don’t rely on a generic one-sentence clause. Negotiate a detailed list of triggering events, specify what each party must do when one occurs (notification deadlines, mitigation efforts, allocation of partially available supply), and include a termination right if the disruption lasts beyond a defined period.
Assignment and Change of Control
When a business is sold, merged, or restructured, its long-term contracts don’t automatically follow. Anti-assignment clauses restrict one party from transferring its rights or obligations to a third party without the other side’s consent. Under the UCC, a party can generally assign rights unless the assignment would materially change the other party’s obligations or significantly increase the burden or risk.7Legal Information Institute. UCC 2-210 Delegation of Performance Assignment of Rights Contract language can override this default and impose tighter restrictions.
Scope matters during acquisitions. Some anti-assignment provisions only block direct transfers of the contract itself. Others extend to equity sales, mergers, and reorganizations, meaning a change in who owns the company triggers the restriction. A buyer acquiring a business often discovers that the target’s most valuable contracts require the other party’s consent before the deal can close. Failing to get that consent can leave the contract unenforceable by the new owner.
If you’re the party whose ownership might change, build flexibility in early. Carve-outs for internal reorganizations and affiliate transfers are standard. Blanket prohibitions on any change of control create unnecessary friction when the time comes to sell. If you’re on the receiving end of a proposed assignment, the consent requirement gives you leverage to renegotiate pricing or update performance terms as a condition of approval.
Dispute Resolution, Governing Law, and Venue
Multi-year contracts produce disagreements. Decide how to resolve them before anyone is angry enough to call a lawyer.
Arbitration or Court
Many long-term agreements include mandatory arbitration clauses requiring the parties to resolve disputes through a private arbitrator rather than a court. Under federal law, a written arbitration provision in a contract involving interstate commerce is valid, binding, and enforceable.8Office of the Law Revision Counsel. 9 USC 2 – Validity, Irrevocability, and Enforcement of Agreements to Arbitrate Arbitration can be faster and more private, and decisions are final with very limited appeal rights.
That finality cuts both ways. If the arbitrator gets it wrong, you are largely stuck. Arbitration also typically eliminates jury trials and limits discovery, which can be an advantage (lower costs, faster resolution) or a disadvantage (less access to the other side’s documents and witnesses). In contracts where the power balance is uneven, the stronger party often prefers arbitration because the weaker party tends to recover less than they would before a jury.
Choice of Law and Venue
A choice-of-law clause determines which state’s legal rules apply to interpreting and enforcing the contract. A venue clause determines where any lawsuit or arbitration physically takes place. These are separate decisions, and both matter. You could agree that New York law governs while requiring any lawsuit be filed in a federal court in Texas. When parties are in different states, whoever gets to litigate on home turf has a real advantage in cost and logistics. A neutral venue, or one geographically reasonable for both sides, often makes the most sense in a long-term relationship where either party might eventually be the one filing a claim.
Amendments
Business conditions change over a multi-year deal. Most long-term agreements include a no-oral-modification clause requiring that any changes be made in a signed written amendment. Under the UCC, a signed agreement that excludes modification except by a signed writing cannot be modified any other way, though courts have sometimes found that a party’s conduct can waive the written-modification requirement through estoppel. Even if the contract says “no oral modifications,” behaving as though a verbal change is binding can undermine that protection.
A formal written amendment should identify the original agreement, describe the specific terms being changed, and state that all other provisions remain in effect. That last point matters more than it sounds. Without explicit language preserving the rest of the contract, an ambiguous amendment can create arguments that other terms were implicitly changed. Keep every signed amendment organized alongside the original so anyone reviewing the deal can trace the current terms without reconstructing a chain of emails.
