MEMORANDUM OPINION AND ORDER
NORDBERG, District Judge.
This case involves an age discrimination claim brought by Curtis Searight, Jr. against his former employer, Kaiser Aluminum and Chemical Corporation. Searight's motion to amend his complaint to include a breach of contract claim and Kaiser's motion for summary judgment are currently pending before the Court. For the reasons stated in the following opinion, the Court denies both motions.

Plaintiff's Motion for Leave to File an Amended Complaint
After examining plaintiff's proposed amendment based upon an alleged breach of contract, the Court denies plaintiff's motion. Although an amendment under rule 15(a) to state a new claim will generally be allowed, C. Wright & A. Miller, Federal Practice and Procedure § 1474 (1971), the trial court may properly deny leave to amend the pleadings when the amendment would not withstand a motion to dismiss. Massarsky v. General Motors Corp., 706 F.2d 111, (3d Cir.) cert. denied, 464 U.S. 937, 104 S.Ct. 348, 78 L.Ed.2d 314 (1983); see Shashoua v. Quern, 612 F.2d 282 (7th Cir.1979). Plaintiff's proposed breach of contract claim is clearly frivolous on its face and cannot withstand defendant's outstanding objections to the amendment or alternatively, its motion to dismiss.
The undisputed facts are that Searight was employed by Kaiser from September 1, 1956 to February 1, 1980. On March 1, 1960, during Searight's tenure, Searight and Kaiser entered into an agreement, ("Agreement"), attached hereto as Appendix A. Searight's proposed amendment is based upon the Agreement.
*19 Essentially, the Agreement provides: 1) that Kaiser would continue to employ Searight as long as both parties mutually agreed to the employment and; 2) that any and all trade secrets or inventions, etc., which Searight conceived or made during his employment would be Kaiser's property. The Agreement further provided that Searight would not disclose such secrets or inventions during or subsequent to his employment without Kaiser's consent. Searight contends that since the Agreement contemplates lifetime performance by him, i.e., not to disclose trade secrets or inventions, that the contract should also be construed to provide lifetime employment for him, unless it is "mutually agreed" that Searight be terminated. Searight argues that the following language of the Agreement also permits such a conclusion:
IT IS MUTUALLY AGREED AS FOLLOWS:
1. Employer employs and shall continue to employ Employee at such compensation and for such a length of time as shall be mutually agreeable to Employer and Employee.
The balance of the Agreement essentially provides for non-disclosure of trade secrets and inventions and makes the Agreement retroactive to the date on which Searight began his employment.
This language of the Agreement and Searight's lifetime promise not to disclose trade secrets cannot, as a matter of law, provide Searight with any breach of contract claim. In the first place, in Illinois an employment relationship is understood to be terminable at any time, with or without cause, by either party, unless a contract specifies a duration. Atwood v. Curtiss Candy Co., 22 Ill.App.2d 369, 161 N.E.2d 355 (1959). However, the Agreement in the instant case did not alter the terminable at will employment relationship.
Under general principles of contract law and Illinois law, which the parties seem to agree governs this case, questions as to the meaning of an unambiguous contract can be appropriately decided upon a motion to dismiss. Egger v. Phillips, 710 F.2d 292 (7th Cir.1983). The preliminary question of whether an ambiguity exists is a question for the court to determine as a matter of law. Joseph v. Lake Michigan Mortgage Co., 106 Ill.App.3d 988, 62 Ill.Dec. 637, 436 N.E.2d 663 (1982). The court must look to the works used in the contract to determine the intent of the parties. E.g., Western Illinois Oil Co. v. Thompson, 26 Ill.2d 287, 186 N.E.2d 285 (1962). Absent ambiguity, the words of the contract are generally the sole indicators of what the parties intended. Sunstream Jet Express, Inc. v. International Air Service Co., 734 F.2d 1258, 1266-1270 (7th Cir.1984); Ambarann Corp. v. Old Beu Coal Corp., 395 Ill. 154, 69 N.E.2d 835 (1946). In other words, a contract is ambiguous only if it is reasonably susceptible to different constructions when read in its plain and ordinary meaning. Susmano v. Associated Internists of Chicago, Ltd., 97 Ill.App.3d 215, 52 Ill.Dec. 670, 422 N.E.2d 879 (1981). These principles of contract construction are applicable to employment contracts as well as other types of contracts. Goodman v. Board of Trustees of Community College, Etc., 511 F.Supp. 602, 605 (N.D.Ill.1981).
Applying these principles to the case at bar, the Court finds that the Agreement can have only one meaning: If either party no longer desires the employment to continue, the employment would no longer be "mutually agreeable" and could be terminated by either party. The Court concurs with the well-reasoned opinion of Chief Judge Haden in Murray v. Kaiser Aluminum & Chemical Corp., 591 F.Supp. 1550 (S.D.W.Va., 1984), interpreting identical language, wherein the court held the contract to be terminable at will, finding that any other construction of the "mutually agreeable" language would be tortured, untenable and a reductio ad absurdum. Id. at 1553. (See Exhibit A to Defendant's Response to Plaintiff's Motion for Leave to File Amended Complaint).
Moreover, the Court does not find persuasive the authority cited by plaintiff wherein Illinois courts have implied a term of duration into an instrument to avoid the terminable at will doctrine. In the two *20 cases cited by plaintiff either the nature of the Agreement or particular language in the Agreement clarified the parties' intentions regarding duration. In Ricke v. Ricke, 83 Ill.App.3d 1115, 39 Ill.Dec. 598, 405 N.E.2d 351 (1980), the court found that the term of a lease could be implied from another provision in the agreement providing for exercise of an option. The option provision, the court found, made the parties' intent as to duration clear. Similarly, in Adkisson v. Ozment, 55 Ill.App.3d 108, 12 Ill.Dec. 790, 370 N.E.2d 594 (1977), the court found that absent a clear provision regarding duration in an agreement to supply water at certain rates, the supplying city could raise rates after furnishing water at the contractual rate for 18 years.
In the same vein, Martin v. Federal Life Insurance Co., 109 Ill.App.3d 596, 65 Ill. Dec. 143, 440 N.E.2d 998 (1982) and Smith v. Board of Education of Urbana School District No. 116 of Champaign, 708 F.2d 258 (7th Cir.1983), simply indicate that in certain circumstances courts will enforce lifetime oral employment agreements supported by consideration other than an employee's services. In the instant case, plaintiff does not allege the existence of a lifetime oral employment agreement based upon additional consideration so as to bring himself within the holding of such cases. Rao v. Rao, 718 F.2d 219 (7th Cir.1983) is also distinguishable from the facts of the instant case for it deals with the law surrounding restrictive covenants which are not alleged to be a part of this case.
For the foregoing reasons the Court finds that plaintiff's proposed breach of contract amendment could not withstand a motion to dismiss. Therefore, plaintiff's motion to amend his complaint to include such a claim is denied.

Defendant's Motion For Summary Judgment
After reviewing the affidavits and deposition testimony, the Court finds that there are genuine issues of material fact precluding summary judgment.
The standard for granting summary judgment in an age discrimination case is clear:
1. The plaintiff must set forth a prima facie case to raise an inference of discrimination, Huhn v. Koehring Co., 718 F.2d 239 (1983); Kephart v. Institute of Gas Technology, 630 F.2d 1217 (7th Cir.1980). To set forth a prima facie case, plaintiff must show: (a) that he belongs to the protected class; (b) that he was qualified for the position; (c) that he suffered an adverse employment decision, and (d) that the employer sought to replace him. Huhn, 718 F.2d at 239.
2. Once the plaintiff sets forth a prima facie case, the burden shifts to the employer to articulate a justification for the adverse employment decision. Id.[1]
3. Once the employer articulates a justification for his decision, the employee must then prove that the justification was merely a pretext  that, but for his age, he would not have been terminated. The employer need only articulate justification for his decision, thus the ultimate burden of proof remains at all times with the employee. Id.
Applying the standards set forth in Kephart and Huhn to the instant case, the Court finds that summary judgment must be denied. Plaintiff has pled an employment history of 23 years and a recent history of satisfactory performance appraisals sufficient to establish a prima facie case. The employer, through the affidavit of C. Jerry Bills, articulated a host of reasons for its adverse employment decision, for example, that plaintiff continually arrived late and left early, that plaintiff caused disruption in Region 6, that the vice president *21 of Inland Steel, a customer of Kaiser, had been highly critical of plaintiff, and that plaintiff failed to monitor the "Detrick Company problem." Although many of the facts underlying these reasons are in dispute, a more significant fact forces the Court to deny summary judgment. It is uncontested that Bills, plaintiff's supervisor, referred to Searight and older employees as "old farts" or "O.F.'s" (Def. Reply Memorandum pp. 10-11). Such a categorization suffices to show that plaintiff's supervisor may have had an age-related animus hostile to older individuals, thereby supporting a pretext theory, i.e., that the employer's termination of plaintiff was due not to dissatisfaction with plaintiff but to an age-related animus. See Scofield v. Bolts & Bolts Retail Stores, 21 FEP 1478, 1480 (S.D.N.Y.1979) (discharged employee made out a prima facie case of age discrimination in view of testimony that employer's store manager referred to her and another employee as "the old women"); see also Mistretta v. Sandia Corp., 15 FEP 1690 (D.N.M.1977), aff'd in relevant part, 639 F.2d 600 (10th Cir.1980). The foregoing evidence thus raises a genuine issue of material fact.

Conclusion
In accordance with the foregoing opinion, Plaintiff's Motion to Amend the Complaint is denied. Defendant's Motion for Summary Judgment is denied.

NOTES
[1]  In Kephart v. Institute of Gas Technology, 630 F.2d 1217 (7th Cir.1980), the Seventh Circuit noted that the soundness of the employer's expectations should not be scrutinized by the court. The ultimate issue is whether the employee was discriminated against because of age. Therefore, the court found that an inquiry into whether the employment decision reflected proper business judgment was in error.
