In February 1968, plaintiff Harold N. Holt commenced an action against defendant Seversky Electronatom Corporation in the United States District Court for the Southern District of New York. Holt alleged a breach of his employment agreement by Sevеrsky and sought $81,666.67 damages for unpaid and lost salary and $1,200,000 damages for the deprivation of certain stock option rights. On March 1, 1971, on motion of defendant, Richard H. Levet, J., granted summary judgment in favor of plaintiff in the limited amount of $1,833.33 on the claim for lost sаlary. Later that day, after plaintiff had rested during the jury trial of the case, the judge dismissed the claim based on the stock option. Plaintiff appeals from the judgment entered pursuant to these rulings. We affirm.
I
The facts may be stated briefly. Following somе months of negotiations, Holt began employment with Seversky in late August 1967, pursuant to an informal agreement which both parties agree contemplated a “trial” period of four to six months. A month later the agreement was reduced to a fоrmal contract of employment for three years. The monthly salary was $1,667.67 until February 1, 1968, and $2,500 thereafter. The agreement granted Holt an option under the corporation’s “Qualified Stock Option Plan” to purchase 20,000 shares of the corporation’s stock, at $2.50 per share. A key provision of the contract incorporated the parties’ understanding of the “trial” period in the following language:
It is understood that the Corporation may terminate this agreement as of February 1, 1968, by giving [Holt] at least thirty days’ written notice prior thereto of its intention of such termination.
In early January 1968, a parting of the ways began. From January 3 to January 15, Holt considered requests by Seversky’s president to extend the trial period at the lоwer salary for an additional six months. Holt finally refused and on January 24 he received written notice that his employment “has been terminated.” One month later, the present action was commenced. The parties agree that New York law applies, and we accept that law as controlling in this diversity action.
II
We agree with the district court’s conclusion that under the “trial” period provision of the employment agreement Seversky’s notice of termination was untimely. Written notice was first given to plaintiff on January 24, rather than on January 2, thirty days prior to February 1. At first blush, then, the question presented by the claim for lost salary 1 appears simple: What are the legal consequences of Seversky’s untimely notice? This quеstion is complicated, however, by the lack of controlling New York authority on the precise point.
Holt contends that Seversky’s failure to give timely notice resulted in the complete loss of its right to terminate the agreement. From this рremise, Holt argues that his discharge was wrongful and, under settled New York law, the proper measure of his damages is prima facie the salary that would be payable to *34 him for the period from the wrongful discharge to the end of the term of employment 2 — in ■ this case, about $80,000. Plaintiff cites no New York authоrity, 3 however, in support of his basic argument that Seversky lost its right to terminate the agreement because of the untimely notice. Plaintiff does call our attention to the statement by Professor Corbin:
The time and manner of exercising a powеr of termination may be specified in the contract; in such case an attempt to exercise it otherwise will be ineffective. * * * A provision that a contract may be terminated at one or more specified dates by giving 30 days notice requires that the notice be given 30 days before one of those dates; and time is of the essence. [Footnotes omitted.]
6 Corbin, On Contracts § 1266, at 65-66 (2d ed. 1962) [Corbin].
Defendant maintains that there was no wrongful discharge here but only a violation by an employer of a notice requirement in exercising an otherwise valid right to terminate. Defendant cites Williston as follows:
In general, where a contract of ordinary employment stipulates for * * * a certain period of notice, the employment may be cancelled on shorter notice or with none at all upon payment of wages or salary for the period of notice.
9 Williston, A Treatise on the Law of Contracts § 1017, at 136 (3d ed. 1967). Under this rule, Seversky would only be liable tо Holt for one month’s pay rather than for the salary due for the remaining contract period of two years and nine months. The rule has been adopted by New York courts, 4 but thus far it has apparently only been applied in situations in which the сontract provided for termination at any time upon the giving of a specified period of notice. In the present situation, the option to terminate was limited to one date — -February 1. Nonetheless, the district court concluded thаt the New York courts would apply their broad rule to the present case, and accordingly the court limited Holt’s recovery to $1,833.33. 5
Since there is an absence of controlling state authority on the proper measure of Holt’s rеcovery, we are forced, as a federal court vested with diversity jurisdiction, to do the best we can in estimating “what the state court would rule to be its law.” Bernhardt v. Polygraphic Co. of America, Inc.,
We do not suggest that this is an open and shut case, but we believe that the trial court was correct in holding that:
[T]he contract provision here was merely indicative of the parties’ intention, when contracting, that plaintiff be given ample notice if defendant did not wish to retain him after the six month trial period of employment was over.
By awarding plaintiff his sаlary for a full notice period, see note 1 supra, the district judge carried out this intention. Plaintiff’s construction of the agreement actually cuts down the trial period from February 1 to January 2, since notice after that date would be ineffectivе. This is inconsistent with the use of February 1 as the date for a 50 per cent increase in salary, obviously coinciding with the end of a trial period. We realize that when a contract contains a specified termination date, if notice is delayed an employee may act to his detriment in reliance thereon, e. g., by buying a house which can later be sold only at a loss. Possibly, the New York courts would then regard the limited measure of recovery (salary for the notice period) as inadequate and would not impose it. But this does not seem to be such a case and we need not speculate about what we should do if it were. We therefore conclude that the measure of recovery adoptеd by the district court was a good estimate of New York law and affirm the order insofar as it granted summary judgment on the issue of lost wages.
Ill
The second argument Holt raises on appeal is that he is entitled to recover the value of certain stock option rights allegedly lost when Seversky discharged him.
The “Qualified Stock Option Plan” under which Holt’s option rights were granted required that an employee whose employment had been “terminated for any cause, other than death” must еxercise his right to purchase the company’s stock within three months of the termination or forfeit his option. Holt concedes that he made no attempt to exercise his option rights by tendering the purchase price. Nonethelеss, he seeks to avoid the impact of the plan’s requirement on two grounds. First, relying on the principle that a party may not profit from his own wrong, Holt maintains that Seversky’s wrongful discharge may not be permitted to accelerate the time рeriod in which he would otherwise have been able to exercise his option. We have held, however, that although the discharge did not conform to the contract’s notice requirement, it was not “wrongful” in the sense Holt urges. The cases сited, 8 therefore, are not persuasive.
Second, Holt asserts that failure to tender the purchase price must be excused because Seversky would have refused the tender, if made. See Strasbourger v. Leerburger,
Accordingly, the district court properly dismissed the cause of action based upon the alleged deprivation of stoсk option rights.
Judgment affirmed.
Notes
. The complaint contained two claims for salary: one for unpaid salary for the period January 1 to 21, 1968, and the other for lost salary after that date. The former was settled by a pre-trial order directing payment for thаt period. For the latter period, the judge awarded $1,-833.33, apparently representing the salary due for one month. The precise manner in which this figure was computed is not clear from the record but, in any event, is not the subject of aрpeal.
