Unreported / Non-Citable
Background
Lexicon Growth LP claimed that Deniz Tortop agreed to sell it shares of privately held Cerebras Systems. The written agreement named Cerebras as a party and stated that it would not become effective until every party, including Cerebras, signed it. Tortop withdrew before Cerebras supplied that approval, and Lexicon sued for breach of contract and breach of the implied covenant of good faith and fair dealing.
The court previously dismissed both claims, concluding that Cerebras’s signature was a condition to formation of any contract rather than merely a condition to later performance. Lexicon asked the court to reconsider, arguing that California law made Tortop’s offer irrevocable once Lexicon accepted, that the parties’ intent required factual development, and that Lexicon should at least be allowed to pursue promissory estoppel based on its alleged reliance. It alternatively requested permission to take an immediate interlocutory appeal.
The Court’s Holding
The court largely refused to reconsider the dismissal. The agreement’s statement that it would not be effective until Cerebras signed was unambiguous. California decisions recognize that when parties expressly condition effectiveness on a third party’s approval, no contract arises before that approval. Because the language was clear, Lexicon could not create an ambiguity merely by proposing a competing interpretation, and its cited post-agreement email did not establish a different shared intent at formation.
California Civil Code section 1586, which addresses revocation before acceptance is communicated, did not change the result. An offeror may define the conditions for acceptance, and nonoccurrence of an express condition can keep an apparent acceptance from producing a contract. Lexicon therefore could not revive its contract claim or amend around the missing Cerebras signature. The court also declined interlocutory certification because disagreement with application of settled contract principles did not establish the exceptional statutory requirements.
The court granted one limited form of relief. Because Lexicon had already received leave to amend another claim, it could add a separately pleaded promissory-estoppel cause of action if factually and legally supportable. That permission did not signal that the new theory would survive another motion to dismiss; it simply allowed the issue to be tested on an amended pleading.
Key Takeaways
- An express clause stating that an agreement is ineffective until a company or other third party signs can be a condition to contract formation, not simply a promise governing performance.
- Acceptance by the proposed buyer does not override an unmet condition that the offer itself makes necessary to create a binding agreement.
- Clear written language generally forecloses discovery into subjective intent; later communications are particularly weak evidence of intent at formation.
- Promissory estoppel may remain a distinct fallback theory, but leave to plead it is not a ruling that detrimental reliance or an enforceable promise actually exists.
Why It Matters
California deal lawyers should treat approval and signature provisions in private-company transactions as outcome-determinative drafting. A clause saying an agreement is not effective until all listed parties sign may permit a seller to withdraw before the final approval, even after the buyer communicates assent. Parties that intend approval only to delay performance should say so directly.
For litigators, the order also illustrates the narrow role of reconsideration. Repackaging interpretation arguments will rarely reopen a dismissal when the writing is facially clear. Any reliance-based alternative should be pleaded separately with concrete allegations about the promise, reasonable reliance, and resulting harm.
