MAJORITY OPINION
SEARS, Justice.
This is an appeal from a judgment awarding appellees $2,500,000.00 in punitive damages in their worker’s compensation wrongful death action. Appellant raises eight points of eiTor. We affirm.
[463]*463Bun Meng Ung was struck and killed by a trailer that became disconnected from a truck as it traveled on Interstate 10. There was a large pothole in the road. When the track hit the hole, the trailer became disconnected and veered into the workmen. Appel-lees sued appellant, the State of Texas, and the Hammerblow Corporation (the manufacturer the trailer hitch). Appellees settled with all defendants except appellant and went to trial solely on the issue of punitive damages.
At the time of the accident, Ung was working for appellant as a member of a crew cleaning debris from the shoulder of the road. Ung’s crew was supervised by Lyle Strandlien. The area in which the crew was working was protected by a closed driving lane, marked by orange steel barrels filled with sand. Two one-ton buffer trucks and a dump truck were placed at the site to shield the workers from errant vehicles. There was conflicting testimony regarding the location of these trucks at the time of the accident. A lighted sign board on the back of each track directed traffic away from the shoulder and the closed driving lane. Appellant had also placed signs ahead of the work site advising motorists of sweepers. The workers themselves wore brightly colored vests supplied by appellant.
Appellant first complains that the damage award violates the United States and Texas Constitutions because the procedures provided the jury no guiding standard and encouraged unlimited discretion. Appellant cites Pacific Mutual Life Insurance Company v. Haslip, 499 U.S. 1, 22-24, 111 S.Ct. 1082, 1046, 113 L.Ed.2d 1 (1991), which sets out three factors for determining whether there were meaningful constraints upon the jury’s discretion in assessing exemplary damages. Those three factors are: (1) whether the jury instructions were adequate, (2) whether there was a post-trial review of the award, and (3) whether appellate review is based on a comparative analysis. 499 U.S. at 22-24, 111 S.Ct. at 1046. We turn first to the adequacy of the instruction given.
The instruction given the jury provided: “Exemplary damages” means an amount that you may in your discretion award as an example to others as a penalty or by way of punishment, (emphasis added).
The purpose of punitive damages in Texas is to punish the wrongdoer, to set an example to others, and to compensate the victim. See Hofer v. Lavender, 679 S.W.2d 470, 474 (Tex.1984). Instructions similar to the one submitted in this case have been upheld as not violative of the U.S. or Texas Constitutions. See, e.g., Missouri Pac. R.R. Co. v. Lemon, 861 S.W.2d 501 (Tex.App.—Houston [14th Dist.] 1993, writ requested). In Lemon, the jury was advised that “exemplary damages” means “an amount that you may in your discretion award as an example to others and as a penalty or by way of punishment, in addition to any amount that you may have found as actual damages.” Id. at 525. A panel of this court held that, although this instruction was not as lengthy as the one upheld in Haslip, it similarly “ ‘enlightened the jury as to the punitive damages’ nature and purpose, identified the damages as punishment for civil wrongdoing of the kind involved, and explained that their imposition was not compulsory’.” Haslip, 499 U.S. at 19, 111 S.Ct. at 1044. Thus, this court held that the Lemon instruction satisfied due process constraints. Lemon, 861 S.W.2d at 525.
Appellant attempts to distinguish Lemon by pointing to the final phrase in the Lemon instruction, “in addition to any amount that you may have found as actual damages,” which is not found in the instruction here. However, such a phrase was unwarranted in this case since no actual damages could be recovered due to the Worker’s Compensation Act. Furthermore, we do not find that phrase crucial to the question whether the jury was given adequate guidance in assessing “punitive” damages.
In Transportation Insurance Company v. Moriel, 37 Tex.Sup.Ct.J. 450 (Feb. 2, 1994), the Texas Supreme Court discussed the constitutional issues surrounding awards of punitive damages. In Moñel, the court stated that Texas jury instructions are the only aspect of Texas procedure to meet or exceed the minimal requirements. Id. at 465 n. 25. In so stating, the court referred to the instructions given the Moriel jury which in-[464]*464eluded the factors set forth in Alamo National Bank v. Kraus, 616 S.W.2d 908, 910 (Tex.1981). By noting that “Texas jurors are instructed on the factors set forth in Kraus ..the court implied that constitutional requirements are met by inclusion of these factors in an instruction. See id. However, such an implication does not necessarily suggest that the court would hold unconstitutional an instruction without the Kraus factors. In any event, the court expressly provided that we may not retroactively apply procedural standards adopted in Moriel. See id. at 463. Besides the questionable implication in Moriel, we find no case law indicating that this instruction violates due process. Thus, we find that the instruction in this case was not error.
We further find that there was extensive post-trial review of the award. Appellant filed a motion for new trial, or in the alternative, a motion for remittitur which included a constitutional challenge to the instruction regarding exemplary damages. Appellants complain that the trial court conducted no meaningful review of the award; however, the entire hearing on this motion focused ~on the award of exemplary damages. Appellant also complains that the trial court did not state on the record its reasons for refusing to interfere with the award. Like the courts in Lemon and Haslip, we find no constitutional violation by the trial court in failing to articulate its basis for the denial of the motion.
Appellate review of awards of exemplary damages involves consideration of 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.
Kraus, 616 S.W.2d at 910. The jury found that appellant committed gross negligence resulting in the death of Ung. The jury heard evidence that the supervisor was aware of the potential danger to his crew because he had observed a prior accident involving a loose trailer in approximately the same location a year before. Furthermore, the evidence was conflicting as to the placement of buffer trucks to protect the crew members, but there was evidence that the placement provided the crew no protection. The trial judge allowed evidence of the possible negligence of parties other than appellant, including the driver of the truck, the owner of the trailer, and the State’s duties with respect to highway repair. The jury also learned that Ung left a wife and four children. We find this evidence sufficient to support the jury’s award under the Kraus factors.
Appellant also asks that we utilize another factor, not included in the Kraus case, to determine whether the award is excessive. This factor is a comparison of the award to the defendant’s net worth. In support of applying this test, appellant cites a number of California cases. Absent any Texas precedent for utilizing this analysis, we decline appellant’s invitation to do so.
Finally, appellant argues that there can be no meaningful comparison between actual damages and exemplary damages in this case because there is no award of actual damages. Indeed, because this is a worker’s compensation case, there can be no award of actual damages. Even so, it does not automatically follow that the award is excessive. Furthermore, an exact amount of actual damages is unnecessary to determine whether exemplary damages are reasonable. Wright v. Gifford-Hill & Co., 725 S.W.2d 712, 714 (Tex.1987). We hold that the award is not excessive under the U.S. or Texas Constitutions.
In addition to arguing that the award is excessive, appellant argues that, as an employer, it was denied equal protection because punitive damages may be awarded against it without any jury award of actual damages. Appellant claims there is no rational basis for drawing a distinction between employers and other plaintiffs. We disagree. A plaintiff in a worker’s compensation case cannot recover actual damages, but waives any common law or statutory rights of action [465]*465in exchange for the receipt of worker’s compensation benefits. Tex.Rev.Civ.Stat.Ann. art. 8306, §§ 3a, 5 (Vernon 1964) (repealed 1989). In actions for exemplary damages, it would be nonsensical to require a plaintiff to plead and submit issues on actual damages which cannot be recovered. Wright, 725 S.W.2d at 714. Furthermore, the lack of such a finding of actual damages does not necessarily result in excessive exemplary damages. Thus, we find a rational basis for allowing plaintiffs in worker’s compensation to recover exemplary damages without having to plead, prove, and obtain jury findings of actual damages. We overrule point of eiTor one.
In point of error two, appellant challenges the legal and factual sufficiency of the evidence supporting the jury’s finding of gross negligence. In determining the legal sufficiency of the evidence, we may consider only the evidence and inferences that tend to support the jury’s finding, disregarding all contrary evidence and inferences. Southern States Transp., Inc. v. State, 774 S.W.2d 639, 640 (Tex.1989). Where a party challenges the factual sufficiency of the evidence, we must consider all of the evidence and we may set aside the finding only if the evidence is so weak as to be clearly wrong and manifestly unjust. Cain v. Bain, 709 S.W.2d 175, 176 (Tex.1986).
The court’s charge defined gross negligence as “such an entire want of care as to indicate that the act or omission in question was the result of conscious indifference to the rights, welfare, or safety of the persons affected.” Gross negligence involves two components: (1) the act or omission, and (2) the defendant’s mental state. Moriel, 37 Tex.Sup.Ct.J. at 458. Thus, gross negligence “differs from ordinary negligence with respect to both elements — the defendant must be ‘consciously indifferent’ and his or her conduct must ‘create an extreme degree of risk’.” Id.
The test for gross negligence contains an objective and subjective component. Wal-Mart Stores, Inc. v. Alexander, 868 S.W.2d 322, 325 (1993). Objectively, the defendant’s conduct must involve an “entire want of care,” distinguishing it in degree or quantity from ordinary negligence. Id. Subjectively, the defendant must have acted with conscious indifference, which means he must have had actual knowledge that harm was a highly probable result. Id. By focusing on the defendant’s mental state, this element “stresses a qualitative distinction from ordinary negligence.” Id.
We turn next to the evidence supporting the finding of gross negligence. Lyle Strandlien, Ung’s supervisor, testified that he had seen an accident in the same area approximately one year earlier involving a disconnected trailer. Therefore, he was aware of the potential danger of working in that area without adequate “buffer” protection. Trucks were parked behind the workers and were not moved forward to protect the workers as they moved forward. Although the exact location of these trucks was disputed, the jury obviously resolved the dispute against appellant. Because the scheduled work in this area was to last only 30 minutes, “buffers” were not moved and concrete barriers were not erected to further shield the workers.
Other witnesses and former employees of appellant testified that they would never place workers in the location of a previous accident without adequate protection. Mr. Little, a former supervisor of safety for appellant, and Mr. Jasper, a former operations manager for appellant, testified that: (1) the accident was foreseeable, (2) they would not have put workmen near the pothole that had caused the first accident, (3) placing the workmen in that place, in that manner, was “unreasonably dangerous” and “ultrahazar-dous,” and (4) appellant should have put out advance warning signs and a flag person. Mr. Searcy, a former supervisor for appellant, testified that he was never given any safety manuals to read and that he would not have put workmen near the pothole. This evidence is sufficient for a jury to conclude that appellant acted with gross negligence. We overrule point of error two.
Appellant claims, in point of error three, that the evidence was “perhaps some evidence of ordinary negligence ...,” and [466]*466that, without a jury instruction on ordinary negligence, the jury had insufficient guidance in evaluating the evidence presented. Appellant requested an instruction on ordinary negligence, but the trial court denied it, finding it not relevant to the issue of gross negligence. Appellant believes the jury needed this instruction to understand the difference in nature and degree between ordinary and gross negligence.
The trial court must submit questions, instructions and definitions that are raised by the pleadings and the evidence. Tex. R.Civ.P. 278. In a worker’s compensation ease, the trial court should not submit questions on ordinary negligence or actual damages because worker’s compensation plaintiffs cannot recover for ordinary negligence. Otis Elevator Co. v. Joseph, 749 S.W.2d 920, 922 (Tex.App.—Houston [1st Dist.] 1988, no writ). We overrule point of error three.
In point of error four, appellant claims the trial court erred in instructing the jury that “gross negligence” does not mean “zero want of care.” This oral definition was given during voir dire and there was no objection. Furthermore, appellant does not discuss this particular point of error in the body of its argument. In point of error five, appellant challenges the trial court’s refusal to submit appellant’s requested question inquiring whether the negligence of the settling defendants proximately caused the occurrence in question. Appellant presents no argument or authority regarding this particular point of error.
A point of error must be supported by argument and authorities to be properly before the court on appeal. Hunter v. NCNB Texas Nat’l Bank, 857 S.W.2d 722, 725 (Tex.App.—Houston [14th Dist.] 1993, writ denied). If a point of error is not supported by argument and authorities, it is waived. Trenholm v. Ratcliff, 646 S.W.2d 927, 934 (Tex.1983). We hold that appellant has waived points of error four and five.
In point of error six, appellant challenges the trial court’s refusal to allow cross-examination of plaintiffs, regarding claims against other parties, because the testimony was “inadmissible [sic] as a prior inconsistent statement and an admission against interest.” The only argument appellant presents, besides restating this point of error, is the statement that appellant, “in its Bill of Exceptions No. 2, established that plaintiffs had previously contended that [the other defendants] were grossly negligent.” Appellant also cites to Tex.R.Civ.Evid. 613(a), 803(24). We agree with appellees that the jury was advised of other negligent acts and the parties responsible for those acts. Because those other defendants had settled with ap-pellees, and the settlement monies were paid for actual damages only, any testimony regarding appellees’ prior causes of action against these defendants for “gross negligence” was also not relevant. We overrule point of error six.
In point of error seven, appellant asserts error in the trial court’s refusal to allow a dollar’ for dollar credit for the prior monies received by plaintiffs from the settling defendants. Under the “one satisfaction rule,” appellant contends it is entitled to a credit for amounts previously received by appellees in settlements with other defendants. Appellant requested such a credit in its Written Election of Settlement Credit, which the trial court denied.
In Stewart Title Guaranty Co. v. Sterling, 822 S.W.2d 1 (Tex.1991), the supreme court offered the following definition of the “one satisfaction rule:”
The one satisfaction rule applies to prevent a plaintiff from obtaining more than one recovery for the same injury. Appellate courts have applied the one satisfaction rule when the defendants commit the same acts as well as when defendants commit technically differing acts which result in a single injury.
Id. at 7. See also First Title Co. of Waco v. Garrett, 860 S.W.2d 74, 78 (Tex.1993) (reaffirming “one satisfaction rule” and allowing credit for amounts received by plaintiff in settlement of separate lawsuit, involving common indivisible injury). Appellees argue that this rule applies only to actual damages that are awarded in satisfaction for the injuries sustained. Appellant contends, however, that because the Sterling court credited set[467]*467tlement proceeds against damages after trebling (claims brought under Tex.Ins.Code Ann. art. 21.21 (Vernon 1981)), credit for the settlement monies in this case should be allowed against the exemplary damage award.
Treble damages are punitive damages. See Pace v. State, 650 S.W.2d 64, 65 (Tex.1983). The “one satisfaction rule” is usually inapplicable to punitive damage awards because punitive damages do not concern compensation; they are, instead, intended to punish the wrongdoer and to deter future similar acts. Ratner v. Sioux Natural Gas Corp., 719 F.2d 801, 804 (5th Cir.1983). Consequently, Texas courts historically allowed credits of settlement monies received as payment for compensatory damages only against actual damages. See Providence Hosp. v. Truly, 611 S.W.2d 127, 135 (Tex.Civ.App.—Waco 1980, writ dism’d). In cases brought under the Deceptive Trade Practices Act, the courts, however, allowed credit after the actual damages award was trebled. See, e.g., id. at 136.
In Truly, the court reasoned that deduction before trebling (where such statutory trebling is authorized) would frustrate the legislature’s purposes for the trebling provisions, would discourage settlement, and prevent the plaintiff from recovering the full award required by statute. Id. Because the judgment in Truly expressly found that the settlement monies were paid “as actual compensatory damages,” the court upheld the trial court’s initial trebling of the award of $15,000.00 in actual damages and the trial court’s credit of the settlement proceeds against only that part of the judgment representing compensatory damages (i.e., $15,-000.00). Id. at 137.
The Texas Supreme Court subsequently overruled Truly ⅛ credit only against actual damages in Sterling. Instead, the supreme court approved the reasoning in Schering Corp. v. Giesecke, 589 S.W.2d 516 (Tex.Civ.App.—Eastland 1979, writ ref'd n.r.e.), a case involving only actual damages and no exemplary damages or trebling. Sterling, 822 S.W.2d at 10. Thus, in cases where actual damages awards may be trebled by statute, the supreme court allows credits of settlement proceeds against the trebled sum, even though this involves crediting the settlement proceeds against the punitive portion of the award. See id.
Despite appellant’s contention that Sterling authorizes credits of settlement proceeds against awards of exemplary damages, we are not persuaded that the supreme court intended Sterling to extend to cases not involving statutory trebling. The policy reasons for crediting settlement monies against a trebled sum of damages are not present in cases that involve no statutory trebling. Furthermore, the courts have consistently held that non-settling defendants are entitled to credit against all sums paid by the settling defendants for the “damages resulting from the common acts of all tortfeasors.” Hill v. Budget Finance & Thrift Co., 383 S.W.2d 79, 82 (Tex.Civ.App.—Dallas 1964, no writ). See also Paschall v. Peevey, 813 S.W.2d 710, 712 (Tex.App.—Austin 1991, writ denied); Schering Corp. v. Giesecke, 589 S.W.2d 516, 519 (Tex.Civ.App.—Eastland 1979, writ ref'd n.r.e.).
In the instant case, the interlocutory order approving the settlement indicated that the settlement monies were paid for “actual compensatory damages only.” Appellant is only entitled to credit for sums paid for damages resulting from common acts and the settling defendants paid no sums representing exemplary damages for gross negligence. Thus, we hold that appellant alone is responsible for its liability for gross negligence, and is not entitled to credit of the settlement monies received by appellees. We overrule point of error seven.
In point of error eight, appellant challenges the trial court’s refusal to disqualify appellees’ attorneys for conflict of interest in having previously represented appellant in litigation. Because the firm representing ap-pellees, Hirsch, Glover, Robinson, <& Sheiness (“Hirsch Glover”), had represented appellant in prior litigation somewhat similar to the present case, appellant brought a motion to disqualify, which the trial court denied. Appellant then brought a motion for leave to file petition for writ of mandamus on this issue in [468]*468the First Court of Appeals, which the court denied in an unpublished opinion.
When presented with a motion to disqualify counsel, a trial court must determine whether the matters involved in the pending suit are substantially related to the factual matters involved in the prior suit. NCNB Texas Nat’l Bank v. Coker, 765 S.W.2d 398, 399-400 (Tex.1989) (orig. proceeding) (emphasis in original). The movant must establish a preponderance of the facts indicating this substantial relation between the two representations. Id. at 400. “Substantially related” means that the two matters are so related that it “creates a genuine threat that confidences revealed to his former counsel will be divulged to his present adversary.” Id. To sustain this burden, the movant must cite evidence of specific similarities capable of being recited in the disqualification order. Id. If the movant meets this burden, the moving party is entitled to a conclusive presumption that confidences and secrets were imparted to the former attorney. Id.
In its motion to disqualify, appellant stated the following facts: appellees are represented by Marietta Maxfield and by the law firm of Hirseh Glover; appellant was represented by Paul Anderson of Hirseh Glover in litigation involving an incident on a highway, raising issues of highway safety and appellant’s safety program; this prior litigation resulted in a settlement payment by appellant of $250,000.00; the incident upon which this prior suit was based occurred in 1984 and the incident upon which the instant case is based occurred in 1985; Hirseh Glover gained substantial knowledge during the prior representation regarding appellant’s operations and safety procedures; and the insurance carrier for appellant in the prior suit is also the worker’s compensation carrier for appellant.
Although appellant’s description of the pri- or matter tends to show similarities, we do not find that appellant met its burden of showing such a substantial relation that it creates a genuine threat of Hirseh Glover’s revelation of appellant’s confidences to appel-lee. Further, appellant does not show that any specific fact brought out in the trial was learned by appellees’ attorneys while they represented appellant. Therefore, we overrule point of error eight.
We affirm the trial court’s judgment.
