Before POWERS, ABOUSSIE and B.A. SMITH, JJ.
BEA ANN SMITH, Justice.
Ricardo Lopez sued the Housing Authority of the City of Crystal City, Texas, alleging retaliatory discrimination in violation of the Whistleblower Act.[1] The trial court rendered judgment on a jury verdict, awarding Mr. Lopez $28,549.57 in past lost earnings, $10,000 in future lost earning capacity, $25,000 for mental anguish, and $100,000 in exemplary damages. The Housing Authority appeals, raising legal and factual sufficiency points of error. We will reverse and render in part, remand in part, modify the judgment in part, and affirm the judgment as modified.

BACKGROUND
Mr. Lopez was employed by the Housing Authority as Assistant Executive Director. Shortly after requesting a legal clarification from the United States Department of Housing and Urban Development (HUD) regarding a possible conflict of interest involving the Housing Authority, Mr. Lopez was downgraded in title and authority and given an extremely poor evaluation. Sometime later he reported to HUD three possible violations by the Housing Authority of federal and local rules. Within less than a week he was demoted to a position earning less than half of his previous salary. Mr. Lopez resigned shortly thereafter and remained unemployed for five and a half months. He sued the Housing Authority alleging a violation of the Whistleblower Act.

STANDARD OF REVIEW
In six points of error the Housing Authority contends the trial court erred because there was no evidence or, in the alternative, insufficient evidence to support the jury verdict. In deciding a no-evidence point, we consider only the evidence and inferences tending to support the finding of the trier of fact and disregard all evidence and inferences to the contrary. We will uphold the finding if more than a scintilla of evidence supports it. See Burroughs Wellcome Co. v. Crye, 907 S.W.2d 497, 499 (Tex. 1995). In deciding a factual-sufficiency point we consider and weigh all the evidence and should set aside the judgment and order a new trial only if the judgment is so contrary to the overwhelming weight of the evidence as to be clearly wrong and unjust. See Cain v. Bain, 709 S.W.2d 175, 176 (Tex.1986). Ultimately this appeal turns on whether the record supports the jury verdict in favor of Mr. Lopez.

DISCUSSION
Violation of the Whistleblower Act
In point of error one the Housing Authority contends the evidence is legally and factually insufficient to support the jury's finding that it retaliated against Mr. Lopez because of his reports to HUD. The Whistleblower Act provides for the recovery of damages and other relief when a governmental entity discriminates against a public employee who in good faith reports a violation of law to an appropriate law enforcement agency. Former Act §§ 554.002, .003. If the employer's discriminatory act occurs within ninety days of the employer's report it is presumed, subject to rebuttal, that the wrongful act was committed because the employee made the report. Id. § 554.004.
The relevant time period spans only four months, beginning in September 1993 and ending with Mr. Lopez's resignation in January 1994. Prior to this period Mr. Lopez had been employed by the Housing Authority for six years; for four of those years he held the position of Assistant Executive Director earning an annual salary of $22,800. By the time he resigned, his position had been downgraded to Clerk (Clerk of the Works) and his salary reduced to $10,400.
*155 On September 28, the Housing Authority Board voted to award a contract to a general contractor whose proposed subcontractor was the brother of the Chairperson of the Board. The following day Mr. Lopez called HUD, the agency which oversees and subsidizes the Housing Authority, informing HUD of a potential conflict of interest and requesting clarification. HUD's legal counsel responded that because the Chairperson had abstained from voting, there were no federal concerns but a legal opinion regarding state law and local regulations would be necessary. Mr. Lopez relayed this information to the Interim Executive Director, and reminded her again on October 22 to seek legal advice. On November 12, Maria Farias assumed the position of Executive Director. Less than a week later, the Chairperson wrote Ms. Farias requesting clarification regarding the possible conflict and noting Mr. Lopez's concerns. Ms. Farias gave Mr. Lopez a copy of this letter. On December 9, he again advised the Board that according to HUD a legal opinion was necessary to resolve any possible violation of state or local regulations; he sent a copy of this letter to HUD. On January 6, the Chairperson sent a letter to HUD, urging HUD to provide the legal clarification because the Housing Authority did not have the funds to seek local counsel. Expressing concern for her brother, the subcontractor who had not yet been paid, the Chairperson stated she saw no conflict of interest and suggested that prompt payment outweighed resolution of the conflicts issue.
Shortly after Ms. Farias arrived on November 12, she proposed increasing her salary from $32,000 to $55,000. Mr. Lopez informed her that a comparability study was required by HUD before her salary could be increased. She replied that she would consider it, but to his knowledge the study was never done. On November 24, the Board voted to change Mr. Lopez's title from Assistant Executive Director to Financial Officer. Although his salary remained the same, the position was lower in the agency's managerial hierarchy and Mr. Lopez no longer exercised as much authority at the agency. Before obtaining HUD approval of the title change the new Director effectively removed him from his duties as Assistant Executive Director. Mr. Lopez was not even informed of the change until December 7, a week after she downgraded his position.
On December 12, less than a month after the new Director began and just forty-five days after Mr. Lopez first reported to HUD, Ms. Farias conducted a written evaluation that recommended demoting or dismissing Mr. Lopez because his work rated only "satisfactory," "below expectations," or "unsatisfactory." Copies were given to Mr. Lopez and the Board. At trial there was testimony that Mr. Lopez had consistently received outstanding evaluations in the past. In fact, he had been seriously considered for the position of Executive Director at least two times, including most recently when Ms. Farias was chosen instead.
The juncture occurred when Mr. Lopez called HUD on January 4, 1994, reporting several possible violations of federal and local rules, including: (1) the Director was living in the housing project in a rent-free unit which HUD had not approved; (2) the Board had voted to waive the usual probationary period for benefits for her without following the proper procedure; and (3) the Board had voted to increase her salary without conducting a comparability study. Mr. Lopez had discussed all three concerns with the Director, Ms. Farias, before he notified HUD. Coincidentally his report to her came just two weeks before he received the poor evaluation. On January 10, he was demoted to Clerk at an annual salary of $10,400. After his appeal to the grievance committee was unsuccessful, Mr. Lopez resigned on January 23.
At trial the jury charge, accompanied by proper instructions, asked, "[d]id the Housing Authority of the City of Crystal City, Texas retaliate against Ricardo Lopez for reporting in good faith to an appropriate law enforcement authority what he believed to be a violation of law?" The jury answered yes. Whether we look at all the evidence or only that evidence favorable to the jury finding, we find the jury could have concluded that the Housing Authority discriminated against Mr. Lopez because he reported agency violations to HUD. Mr. Lopez was given a *156 poor evaluation and his title changed less than two months after he reported the first violation to HUD. Less than a week after Mr. Lopez reported the other three violations, he was demoted to Clerk, incurring a substantial pay cut. Under the statute the jury was free to presume a causal link existed between the reports and the discriminatory acts. Although there was testimony that Mr. Lopez had neglected to take care of certain agency business, Mr. Lopez testified that some of the tasks were not performed because he was out of the office on approved leave and that obstacles imposed by Ms. Farias herself prevented him from completing other tasks. The jury could have chosen to believe Mr. Lopez and concluded that the basis given for his demotion was pretextual. A witness for the Housing Authority implied that Mr. Lopez was demoted because he was rude, refused to do his work, and had "an attitude" regarding Ms. Farias. On crossexamination the attorney for Mr. Lopez asked this witness:
Q: ... What did you witness, personally, that makes you testify that way?
A: In some of thesometimea few of the meetings we had in the office, staff meetings, he was always contradicting what [the Executive Director] had to say; what had to be done.
Q: Telling her that she wasn't doing it by the rules and regulations?
A: Yes.
The jury could have chosen to believe the actual testimony rather than the implication. We hold there is some evidence to support the jury's finding of retaliation and that finding is not so contrary to the overwhelming weight of the evidence as to be clearly unjust. We overrule point of error one because the evidence is both legally and factually sufficient to support the jury verdict.
Past Lost Earnings
The Housing Authority claims in point of error two that the trial court erred in rendering judgment for past lost earnings in the amount of $28,549.57 because the evidence did not support such a finding. Past lost earnings are the actual lost income due to the retaliation minus any benefits received, such as unemployment or income from a new job; the amount is calculated from the time of retaliation to the date of trial. Mr. Lopez introduced in evidence a chart listing his past lost earnings as (1) lost salary ($5,687.43); (2) unpaid compensation time ($396.06); (3) unpaid vacation time ($1,618.40); and (4) lost benefits ($20,847.68). Mr. Lopez calculated his lost salary based on the week he worked at the Housing Authority at a decreased salary plus income lost during his five and a half months of unemployment, less unemployment benefits. Mr. Lopez did not testify as to his new salary and, therefore was unable to calculate any dollar amount lost between the time he began his new job and the date of trial. He also submitted evidence which revealed that the agency calculated his accumulated compensation and vacation time using his reduced salary after the demotion rather than his former salary as Assistant Director. Mr. Lopez also testified that he lost $1100 in medical and life insurance benefits, as part of lost benefits, the amount he would have received had he not been demoted. Those amounts for which Mr. Lopez introduced sufficient evidence total $8801.89.
While Mr. Lopez' testimony was sufficient to support the monetary awards for lost salary, unpaid compensation time, unpaid vacation time, and insurance benefits, we find little evidence to uphold the entire award of $20,847.68 for lost benefits. Under lost benefits, Mr. Lopez sought damages for retirement, medical and life insurance, social security, vacation, sick leave, holidays, and annual salary adjustment. Mr. Lopez did not provide a monetary breakdown of these elements and, thus, failed to provide a sufficient basis for arriving at this total for lost benefits. Furthermore, we decline to uphold any damages for loss of an "annual salary adjustment," which is a bonus given at the discretion of the Housing Authority. We find the evidence both legally and factually insufficient to support an award of $20,847.68 for lost benefits with the exception of $1,100 in insurance. While we uphold $8801.89 in damages for lost salary, underpaid compensation and vacation time, and lost health and life insurance benefits, we sustain the second *157 point of error as to the balance of $19,747.68 in lost benefits.
Future Lost Earning Capacity
In point of error three the Housing Authority claims the trial court erred in rendering judgment for future lost earning capacity in the amount of $10,000 because the evidence does not support such a finding. Recovery for future lost earning capacity is available under the Whistleblower Act. See City of Ingleside v. Kneuper, 768 S.W.2d 451, 457 (Tex.App.Austin 1989, writ denied). However, the amount awarded must be based on something more than mere conjecture and must be "proved with that degree of certainty of which the case is susceptible." Id. at 458-59 (quoting McIver v. Gloria, 140 Tex. 566, 169 S.W.2d 710, 712 (1943); see also Bonney v. San Antonio Transit Co., 160 Tex. 11, 325 S.W.2d 117, 121 (1959). After his demotion Mr. Lopez's salary was reduced to $10,400. The jury may have surmised that such a demotion placed Mr. Lopez at a disadvantage in the job market, thereby subjecting him to future losses. On the other hand, Mr. Lopez had every opportunity to present evidence illustrating the exact disadvantage he suffered in lost future earnings as a result of his demotion. He testified that, after his resignation, five and half months passed before he became employed again, but conspicuously failed to testify as to his new salary. Without any evidence that his earning capacity had in fact been diminished, the jury was left to merely speculate about Mr. Lopez's future loss of earning capacity. Facts existed but were not revealed which could have provided the jury a basis for an intelligent answer. Because Mr. Lopez failed to testify as to any basis for loss of future income, we hold there was legally and factually insufficient evidence to support the jury award for future lost earning capacity.
Mr. Lopez's claim that the $10,000 represents the salary decrease from Assistant Director (later Financial Officer) to Clerk is inapplicable here. Lost earning capacity addresses that which he will be unable to make in the future due to the retaliatory demotion. Under his theory, the $10,000 represents lost wages; these are an element of past lost earnings. Mr. Lopez has already received damages for the lost salary caused by his pay cut and unemployment under his claim for past lost earnings. We sustain point of error three.
Mental Anguish
The Housing Authority contends the trial court erred in awarding damages in the amount of $25,000 for past mental anguish because the evidence did not support such a finding. We agree. The trial court properly defined mental anguish as a "relatively high degree of mental strain and distress ... more than mere disappointment, anger, resentment, or embarrassment, although it may include all of these. It includes mental sensation of pain resulting from such painful emotions such as grief, severe disappointment, indignation, wounded pride, shame, despair, or public humiliation." See Saenz v. Fidelity & Guar. Ins. Underwriters, 925 S.W.2d 607, 614 (Tex.1996); Wichita County v. Hart, 892 S.W.2d 912, 926 (Tex.App. Austin 1994) (citing Kneuper, 768 S.W.2d at 460), rev'd on other grounds, 917 S.W.2d 779 (Tex.1996). However, mental anguish damages may not be awarded without "direct evidence of the nature, duration, severity of [plaintiff's] anguish, thus establishing a substantial disruption in his daily routine" or other evidence of a high degree of mental pain and distress. Saenz, 925 S.W.2d at 614 (quoting Parkway Co. v. Woodruff, 901 S.W.2d 434, 444 (Tex.1995)); see Hart, 892 S.W.2d at 926 (requiring plaintiff to show mental anguish beyond mere worry, disappointment or anger) (emphasis added).
In the present case we find that Mr. Lopez offered no evidence to support the jury's finding that he suffered past mental anguish. In an attempt to support the finding he offers the following testimony:
Q: Why did you resign?
A: The cut in payI wouldn't be able to make my ends meet with the proposed salary. And I felt that the position was inappropriate, you know, for the education that I had; the Clerk of Works position.
. . . . .

*158 Q: Was [Mr. Lopez] a good candidate [for Executive Director]?
A: I believe he was one of the top candidates.
. . . . .
Q: Did she tell you what subordinates or fellow workers you were not working well with?
A: No, she didn't.
In essence, Mr. Lopez attempts to present testimony regarding his reputation and market potential as evidence that he suffered mental anguish without offering any testimony as to whether he even felt any emotion. No other portion of the testimony even arguably relates to mental anguish.
In both Hart and Kneuper the plaintiffs put forward some showing of mental anguish in order to recover damages. One testified that he felt "angered and embarrassed," that the termination caused marital problems and that he suffered from lack of sleep. Hart, 892 S.W.2d at 926-27. In Kneuper, the plaintiff stated that he felt "total panic" and "great fear," while his wife stated that he was nervous and irritable and short with the children. Kneuper, 768 S.W.2d at 460. Here, there is no such testimony. Because Mr. Lopez did not offer any testimony relating to his emotional state or its consequences, we find there was neither legally nor factually sufficient evidence to support the jury's award of damages for past mental anguish. We sustain point of error four.
Malice
In point of error five the Housing Authority claims the trial court erred because the evidence was legally and factually insufficient to support the finding of malice necessary to award exemplary damages. See Kneuper, 768 S.W.2d. at 457. The jury charge asked whether the Housing Authority acted "willfully and maliciously" in its conduct and included the following definition:
`Willfully and Maliciously' means an intentional doing of a wrongful act without just cause or excuse; that is, if a wrongful act is done intentionally without just cause or excuse for believing it to be right or legal, or done with conscious disregard to the rights of others, then such an act is willfully or maliciously done. Willfulness and intent may be inferred by the actions and conduct of the wrongdoer.
The Housing Authority claims the jury instruction was incorrect in that it failed to ask the jury to find a "specific intent by defendant to cause substantial injury."[2] The supreme court recently discussed the level of proof required to support an award of punitive damages in a suit under the Texas Anti-Retaliation law. See Continental Coffee Prods. v. Cazarez, 937 S.W.2d 444 (Tex.1996). The court held that actual malice, as evidenced by ill-will, spite, or specific intent to cause injury, was required before punitive damages could be assessed against an employer for violating the statute. Id. at 454. Although the Housing Authority proposes that we review the evidence under a Cazarez definition of malice, this case was tried and the verdict handed down before Cazarez was issued. Furthermore, the agency neither objected to nor requested a different instruction regarding malice when the trial judge specifically asked for objections. See Tex.R. Civ. P. 272. Consequently, it failed to preserve any complaint regarding the jury charge. See Tex.R.App. P. 33.1 (former Rule 52(a)). On appeal, parties are restricted to the theory on which the case was tried. See City of San Antonio v. Heim, 932 S.W.2d 287, 291 (Tex.App.Austin 1996, writ denied) (citing Davis v. Campbell, 572 S.W.2d 660, 662 (Tex.1978)). We will therefore summarize and review the sufficiency of the evidence under the definition of malice submitted to the jury. See id.
The bulk of evidence showing malice involves the Director's December 12 evaluation *159 of Mr. Lopez. She completed an extensive questionnaire regarding his productivity, quality of work, punctuality, degree of supervision required, response to supervision, attempts to improve, ability to work with others, interest in work, persistence, flexibility, ability to express self verbally and in writing, response to crisis, and overall job performance. Ms. Farias found Mr. Lopez's performance "below expectations" or "unsatisfactory" in most of the categories; she also commented that he needed to follow her and the Board's directives and policies, and to learn to work with supervisors, subordinates, and fellow workers. We first note that Ms. Farias made this evaluation only one month after she took the position of Executive Director. During that month, Ms. Farias and Mr. Lopez had worked together only eleven days. Mr. Lopez testified that before the evaluation, there had been no mention of dissatisfaction with his job performance; on occasion the Director told him that he was doing a good job. Second, on December 12, Ms. Farias listed his failure to purchase computer software as one of two reasons for the poor evaluation, although she had given him until the end of December to complete that job. When he reminded her of this time table, she refused to reconsider the poor evaluation. Third, although Ms. Farias placed Mr. Lopez on probation for six months, she did not outline a plan of what he needed to do to improve his performance. She did not list any of the policies he had failed to follow or name any of the coworkers who found him uncooperative. This poor evaluation was then relied on to demote Mr. Lopez.
Additionally, the Director demanded in a memo that Mr. Lopez train employees on computer software within seventy-two hours. She then issued conflicting orders, telling him the training could be done later. Nonetheless, Mr. Lopez's demotion was, in large part, based on his failure to train the employees within the time period requested. From mid-December to the first week of January, several events occurred which also evince that the Housing Authority acted with malice. It claimed Mr. Lopez was demoted because of his failure to purchase computer software and to train employees. Ms. Farias sent him several memos addressing these failures on the days when he was out of the office on approved leave due to a death in his family and personal illness. Insensitive to Mr. Lopez's personal difficulties, the Housing Authority faulted him for not responding immediately to the memos even though he was out of the office during most of that time period. The agency also claimed that rent checks and cash were found in Mr. Lopez's file cabinet rather than on deposit in the bank or safety vault. Mr. Lopez had a reasonable excuse for not getting to the bank and, in fact, he was prevented from leaving the checks and cash in the office vault because Ms. Farias had changed the combination without telling Mr. Lopez, despite his financial duties.
The trial court instructed the jury to find malice if a wrongful act was done "intentionally without just cause or excuse of believing it to be right or legal, or done with conscious disregard to the rights of others." Under this definition we believe the jury could have found malice. The jury's finding must be upheld unless it is so against the great weight and preponderance of the evidence as to be manifestly unjust or erroneous. See Pool v. Ford Motor Company, 715 S.W.2d 629, 635 (Tex. 1986). In light of the whole record we conclude the evidence is both legally and factually sufficient to support the jury's finding of malice.
Exemplary Damages
In its sixth point of error the Housing Authority claims the trial court erred in rendering an award of exemplary damages in the amount of $100,000 because it was excessive and there was legally and factually insufficient evidence to support the award. An appellate court reviews an exemplary damages award to ensure that it is reasonable in its amount and rational in light of its purpose to punish malicious conduct and deter repetition. See Heim, 932 S.W.2d at 294. We may reverse an exemplary damages award or suggest a remittitur only if we determine that the evidence supporting the award is so factually insufficient or the verdict is against the great weight and preponderance of the evidence as to be manifestly *160 unjust. See id. (citing Moriel, 879 S.W.2d at 30). In reviewing the award, we consider the following factors: (1) the nature of the wrong; (2) the character of the conduct involved; (3) the degree of culpability of the wrongdoer; (4) the situation and sensibilities of the parties concerned; and (5) the extent to which such conduct offends a public sense of justice and propriety. See Heim, 932 S.W.2d at 294 (citing Alamo Nat'l Bank v. Kraus, 616 S.W.2d 908, 910 (Tex.1981)). To determine whether the award is excessive, we must detail the relevant evidence and explain why, in light of the Kraus factors, the evidence either supports or does not support the exemplary damages awarded. See Heim, 932 S.W.2d at 294 (citing Ellis County State Bank v. Keever, 888 S.W.2d 790, 798 (Tex. 1994)).
We assess the nature of the wrong in light of the purposes underlying the Whistleblower Act: (1) to protect public employees from retaliation by their employers for reporting violations of law in good faith, and (2) to secure in consequence lawful conduct on the part of those who direct and conduct the affairs of public bodies. See Travis County v. Colunga, 753 S.W.2d 716, 718 (Tex.App. Austin 1988, writ denied). Although Mr. Lopez was not reporting a violation of a health or safety code, he was in good faith reporting a violation by a public agency of its governing regulations. The short period between his report and his demotion suggests a retaliatory animus. The Director's conduct, her friendship with the Chairperson, and the surrounding evidence indicate Ms. Farias harassed Mr. Lopez in a personal manner by making it difficult, almost impossible, for him to do his job well. The Housing Authority cannot avoid responsibility for the caustic behavior of its Director.
In this employment context, the relative situations of the Housing Authority and Mr. Lopez were unequal. While Mr. Lopez could and did point out possible violations, he could not force Ms. Farias or the Board to follow the regulations. Only the Director and the Board were in the position to ensure that regulations were followed or to retaliate against employees who prodded them to comply with regulations and then reported seeming violations. Although Mr. Lopez was not obligated to report violations or to persist in informing HUD and the Housing Authority that regulations were being broken, he did so, regardless of the obvious consequences. The Housing Authority apparently assumed that by demoting Mr. Lopez his persistence would disappear, his reports would stop, or perhaps, he would just quit. Such actions should not be condoned. The Housing Authority is a public agency whose business is to administer affordable housing to families in Crystal City. The Whistleblower Act was designed to protect employees who urge public agencies to conduct their affairs honestly and correct their mistakes. The Act provides for exemplary damages when such an employee is harassed or treated in a punitive manner. We cannot say that the jury acted unreasonably by awarding exemplary damages in the amount of $100,000. Because the evidence is both legally and factually sufficient to support the award, we overrule point six.
Prejudgment Interest
In point of error seven, the Housing Authority claims the trial court erred in awarding prejudgment interest on exemplary damages because Mr. Lopez is not entitled to such interest under Texas law. See Tex. Civ. Prac. & Rem.Code Ann. § 41.007 (West Supp.1997). Mr. Lopez concedes he is not entitled to prejudgment interest on exemplary damages. We sustain point of error seven.

CONCLUSION
Finding no evidence to support the jury's award for future lost earning capacity or mental anguish, we reverse the trial court and render judgment that Mr. Lopez take nothing on those claims. We modify the trial court's judgment to reduce the award for past lost earnings from $28,549.57 to $8801.89 because we find no basis for $19,747.68 of the award for lost benefits. We reverse the trial court's award of prejudgment interest and remand that portion of the cause for recalculation consistent with this *161 opinion. In all other respects, the judgment of the trial court is affirmed.
NOTES
[1]  Because the 1995 amendments govern conduct occurring after June 15, 1995, the 1993 version of the Whistleblower Act applies in this case. See Act of May 4, 1993, 73d Leg., R.S., ch. 268, § 1, 1993 Tex. Gen. Laws 583, 609-11. (Tex. Gov't Code Ann § 554.001-.009 (West 1994), since amended) ("Former Act").
[2]  The Housing Authority also claims the instruction failed to require a finding that "the act or omission viewed objectively involved an extreme degree of risk of which [d]efendant had actual subjective awareness of the risk involved." This definition has been used only in personal injury cases in which exemplary damages are awarded for gross negligence. See, e.g., Transportation Ins. Co. v. Moriel, 879 S.W.2d 10, 23 (Tex.1994). We find that definition inapposite in the present case.
