This appeal grows out of a diversity action brought by the plaintiff-appellant, Chase Manhattan Bank (Chase), against the defendant-appellee, E.B. Rood, to recover on a personal guaranty.
During the summer of 1979, Chase made a loan to Special Event Entertainment (SEE), a movie production company. Rood, a- Tampa, Florida attorney, participated in the financing. SEE collateralized the loan by obtaining letters of credit from a Tampa bank and then making an irrevocable assignment of those letters to Chase. The Tampa bank issued the letters based on a personal guaranty executed by Rood. Chase soon became concerned about unpaid interest on the loan. A Chase officer, Fred Solana, discussed the delinquency with Rood during a luncheon meeting in New York on August 23, 1979. The controversy here centers on the events that transpired during that meeting. According to Chase, Rood agreed to give an unconditional personal guaranty assuring payment of the *436 interest on the SEE loan. Chase further asserts that Rood requested the bank to forego the collection of the interest payments by way of set-off against SEE’s account. By contrast, Rood claims that he promised to direct SEE to deposit funds in its checking account at Chase, so that the bank could collect the interest via a set-off against those monies. He says that the parties understood the written guaranty to be conditioned upon his failure to obtain that transfer or the failure of SEE to maintain adequate funds to meet the interest obligations.
As a consequence of the meeting, Rood mailed Chase a one line letter containing an unconditional guaranty. About the same time, SEE made large deposits in its Chase checking accounts. The bank evidently used the funds to honor outstanding checks written against the account. When SEE failed to pay the interest in accordance with the loan agreement, Chase collected the approximately $8,000.00 remaining in the account and applied it to the interest due on the note. The bank then made a written demand on Rood for the balance of the interest. He refused payment and Chase filed this suit.
During the course of the trial, Rood attempted to give his version of the August 23, 1979 conversation with Solana. Chase promptly objected on the ground that the parol evidence rule barred such testimony. The district court summarily overruled the objection and the testimony became a part of the evidence before the jury. At the close of the case, the trial court submitted a special verdict to the jury, pursuant to Fed. R.Civ.P. 49(a). In response to the questions included in that verdict, the jury found that Rood’s letter constituted a guaranty, that the guaranty was supported by valid consideration, but that the parties orally agreed that Chase would first collect the interest from funds placed in SEE’s checking accounts. This third finding absolved Rood from liability, so the jury did not answer the remaining three questions pertaining to damages. The district court entered a judgment in accordance with the verdict and denied Chase’s motions for a judgment notwithstanding the verdict and for a new trial, which reasserted the parol evidence objections. Because the district court erred in admitting Rood’s testimony concerning his conversation with Solana, we reverse.
Under Florida law,
1
evidence of a prior or contemporaneous oral agreement is inadmissible to vary or contradict the unambiguous language of a valid contract.
E.g., Anderson v. Trade Winds Enterprises Corp.,
*437
In
Anderson,
the guarantors attempted to disclaim liability on a guaranty,
2
despite its categorical language. They alleged that they actually agreed only to guarantee payment in the event that the obligee, in the exercise of due diligence, could not collect from the maker of the note.
Similarly, in
Florida State Bank of Tallahassee v. Honey,
[t]he testimony here related only to the intent of the parties at the time the guaranty contract was executed. Such parole evidence of intent was not admissible. Parol evidence may not be used to create ambiguity in an unambiguous agreement.
Id.
(emphasis in original);
see also Taran v. Sea Coast Appliance Distributors, Inc.,
Anderson and Honey dictate the result in this case. Rood’s letter was unequivocal; it simply stated, “[t]his letter is to serve as my personal guarantee that I will pay the interest due your bank by Special Event Entertainment.” There is not even a suggestion that the obligation was contingent upon Chase’s inability to collect the interest from SEE’s bank accounts. The letter contained an unconditional guarantee and, in the absence of any ambiguity, Rood’s parol testimony about a disputed oral understanding between the parties was inadmissible. Like the agreement at issue in Anderson, the letter created an absolute, guaranty as a matter of law.
In an effort to circumvent the clear import of these cases, Rood advances two arguments. First, he urges the admissibility of his testimony under an exception to the parol evidence.rule. In
Mallard v. Ewing,
Predictably, Rood characterizes his testimony at the trial as evidence of a contemporaneous oral agreement that induced the execution of the written guaranty. For that reason, he claims, the parol evidence rule did not bar its introduction.
3
We do not believe, however, that his testimony falls within the contours of the exception. In
Mallard,
the court emphasized that the inducement exception “requires the agreement to be shown by evidence that is clear, precise, and indubitable; that is it shall be found that the witnesses are credible, that they distinctly remember the facts to which they testify, and that they narrate the details exactly and that their statements are true.”
Rood also claims that, by failing to object to his testimony about the alleged oral agreement and later introducing testimony on the issue itself, Chase waived its right to assert the error on appeal. This contention is refuted by the record. At Rood’s first mention of an oral agreement different from that contained in the letter, Chase promptly objected on the ground that parol testimony was inadmissible to vary the terms of the unambiguous guaranty. Trial Transcript at 35. After the lunch recess, the bank renewed its objection, this time in the form of a motion to strike. Id. at 109. Chase again reiterated its position in its motion for a directed verdict made at the close of the evidence. Id. at 175-176, 179. During the charge conference the plaintiff reminded the court of the objection. Id. at 200. Chase also specifically objected to the submission of the third in- *439 terrogatory dealing with an oral agreement. Id. at 264. Finally, the bank relied primarily on this point in its motion for a judgment notwithstanding the verdict and motion for a new trial.
In spite of this diligent effort, Rood insists that the plaintiffs eventual submission of testimony on the issue, as well as its acknowledgment that if the issue was properly in the case, it should be decided by the jury, essentially amounted to a consent to admit the testimony. It would be unfair to place the plaintiff in the untenable predicament of foregoing any rebuttal of Rood’s defense after failing in its vigorous attempts to exclude that evidence. “Otherwise, a party would unfairly be required to give up its opportunity to convince the jury to find in its favor in order to preserve its right to raise evidentiary issues on appeal.”
Clark v. City of Los Angeles,
In summary, we conclude that Rood’s challenges to the application of Florida’s parol evidence rule are without merit. That rule precludes the use of parol testimony to contradict the unconditional guaranty contained in his letter to Chase.1 ***

Accordingly, we REVERSE the judgment of the district court and REMAND the case with instructions to enter a judgment in favor of the plaintiff on the issue of liability and such further proceedings not inconsistent with this opinion.
See, e.g., United States v. Crawford,
REVERSED and REMANDED.
Notes
. Although federal law ordinarily governs the admissibility of evidence in a diversity action, the parol evidence rule is treated as a rule of substantive law. See,
e.g., Southern Stone Co., Inc. v. Singer,
See Southern Stone Co.,
. The agreement at issue in that case read,
[i]n the event of failure on the part of The Trade Winds Enterprises Corporation to meet the conditions of the above note, payment of this note is further guaranteed by The Four Saints, Walter A. Bouillet, Douglas E. Evans, John R. Howell, Gerald L. DuChene and Robert W. Erickson.
. To some extent, the two lines of authority relied upon by the parties appear to be contradictory. On the one hand, the facts in
Healy
resemble those in this appeal, in that the owners claimed that a facially unconditional agreement was subject to an exception orally agreed upon.
. We do not mean to imply that Rood’s testimony necessarily lacked credibility. Rather, we do not believe that, when the existence of the contemporaneous oral agreement rests solely on a credibility choice between two witnesses, the proof of that accord is “clear, precise, and indubitable.”
See Mallard,
. In view of our conclusion that the parol testimony was inadmissible, we need not reach Chase’s other contention that Rood was foreclosed from presenting his defense since it was not disclosed either in the pleadings or his pre-trial submission.
