OPINION
In this case, an employee of a nonsub-scriber to workers’ compensation insurance voluntarily elected to participate in an employee benefit plan that provided specified benefits in lieu of a common law remedy. The employer, Silsbee Hospital, Inc. d/b/a Columbia Silsbee Doctors Hospital, contends that under the employee benefit plan the employee, Lonny George, waived his common law rights to sue for personal injuries. The Hospital raises additional errors regarding: (1) the trial court’s refusal to grant it additional strikes for certain veniremembers it challenged for cause, (2) the trial court’s evidentiary rulings to exclude evidence arguably relevant to its affirmative defenses of waiver, release and estoppel, (3) the trial court’s broad form damage submission and refusal to submit a damage charge with segregated elements of damage, (4) the jury’s arguably excessive damage award, and, (5) the refusal of the trial court to allow it to amend its pleadings to assert the affirmative defense of ratification.
While descending a ladder on February 29, 1996, George was injured when the ladder slipped and he fell. He received multiple fractures of the bones in his foot and, subsequently, had three surgeries as a result of his injuries. A jury awarded George $1,000,000 in his suit against the Hospital. The award consisted of $100,000 for past damages and $900,000 for future damages.
Applying the rules of contract construction, as further discussed below, we hold that the waiver George signed does not expressly apply to relieve the Hospital of its potential liability at common law. We find the trial court erred in failing to grant additional strikes in jury selection. We also find this error was harmful and requires us to reverse and remand.
The Waiver Agreement
Prior to his injury, George elected to participate in an employee benefit plan and, in doing so, waived certain rights to bring negligence suits for on-the-job injuries. On February 14, 1996, George signed a document titled “ELECTION TO PARTICIPATE IN THE EMPLOYEE HEALTH AND SAFETY PROGRAM BENEFIT PLAN OF COLUMBIA/HCA HEALTHCARE CORPORATION.” The document (hereafter referred to as the “waiver agreement”) states, in all capital letters, “EXECUTION OF THIS DOCUMENT INVOLVES THE WAIVER AND RELEASE OF VALUABLE LEGAL RIGHTS.” The waiver agreement further provides:
By execution of this document, I hereby voluntarily elect to participate in the Employee Health and Safety Program Benefit Plan of Columbia/HCA Healthcare Corporation (the “Plan”). AS REQUIRED BY THE TERMS OF THE PLAN, I, THE UNDERSIGNED, HEREBY FREELY, IRREVOCABLY AND UNCONDITIONALLY RELEASE,. WAIVE AND AGREE NOT TO SUE UPON, ANY AND ALL CLAIMS AND CAUSES OF ACTION, WHETHER NOW EXISTING OR ARISING IN THE FUTURE, THAT I MAY HAVE AGAINST COLUMBIA/HCA HEALTHCARE CORPORATION, ITS SUBSIDIARIES, ITS OFFICERS, DIRECTORS, SHAREHOLDERS, AGENTS AND EMPLOYEES, THAT ARISE OUT OF OR ARE RELATED TO INJURIES OR DEATH SUSTAINED BY ME IN THE COURSE AND SCOPE OF MY EMPLOYMENT *289 BY COLUMBIA/HCA HEALTHCARE CORPORATION AND ARE CAUSED BY THE SOLE NEGLIGENCE OF COLUMBIA/HCA HEALTHCARE CORPORATION OR THE NEGLIGENCE OF COLUMBIA/HCA HEALTHCARE CORPORATION CONCURRENT WITH THE NEGLIGENCE OF ANY OTHER PERSON OR ENTITY....
The Hospital maintains that by participating in the plan and accepting benefits 1 , George waived his right to sue the Hospital. George contends that his injury was sustained in the course and scope of his employment with the Hospital, and not in the course and scope of his employment with Columbia/HCA Healthcare Corporation, the parent corporation of the Hospital. George further contends that under the express terms of the plan he waived only his rights to sue the parent, but retained his rights to sue the Hospital, a subsidiary of Columbia/HCA.
In its first issue, the Hospital asks this Court to reverse the trial court and render judgment in the Hospital’s favor. Alternatively, the Hospital seeks reversal and remand. To support its rendition argument based on waiver, the Hospital relies on
Lawrence v. CDB Services, Inc.,
The Texas Supreme Court further determined that employers who enroll employees in non-subscriber benefit plans as allowed by
Lawrence
must satisfy both components of the fair notice requirements, namely, the express negligence doctrine and conspicuousness.

Id.
at 191. When the fair notice requirements apply, a contract must satisfy both requirements to avoid being unenforceable as a matter of law.
Id.
at 192 (citing
Dresser Indus., Inc. v. Page Petroleum, Inc.,
Relying on
Victoria Bank,
George maintains the document addresses only his right to pursue claims arising from injuries he received while working as an employee of Columbia/HCA, the parent, and not while working as an employee of the Hospital. See
Victoria Bank & Trust Co. v. Brady,
In our review of the waiver agreement, we utilize the rules of contract construction applicable to indemnity agreements and releases.
See Associated Indem. Corp. v. CAT Contracting, Inc.,
In addition to the express negligence rule, we also consider other rules of contract construction in construing non-subscriber agreements.
See Associated Indem. Corp.,
The agreement George signed is not ambiguous as it can be given a definite legal meaning. The clear and unambiguous language found within the fur corners of the document here addresses only injuries arising out of George’s
employment by Columbia/HCA Healthcare Corporation.
It is not disputed that George’s injuries arose out of his employment by the Hospital, which, although a subsidiary of Columbia/HCA, is a distinct legal entity under Texas law.
BMC Software Belgium, N.V. v. Marchand,
The Hospital argues that the agreement it drafted, if interpreted as limited to claims arising out of the employment by Columbia/HCA, would be absurd. However, we note that an employee under Texas law may move into, and out of, his employer/employee relationship with one entity and into an employer/employee relationship with another entity depending upon which entity controls the details of his work at the time of the injury.
See Producers Chem. Co. v. McKay,
We further note that in the Bill of Exceptions the Hospital presented affidavits of the Risk Manager for Silsbee Hospital, Inc., Alice O’Quin, and the Vice President — Legal & Corporate Secretary for Columbia/HCA Healthcare Corporation, John Franck II. However, there was no testimony from either of them explaining the reason the waiver agreement limited the waiver to injuries arising from employment by Columbia/HCA. We also note there was no testimony from any witness at trial, or testimony offered and excluded by the trial court, explaining why the waiver agreement limited the injuries released to those arising out of employment by Columbia/HCA, and did not expressly extend to include injuries arising out of employment by its subsidiaries. There was no explanation by any of the witnesses establishing who owned the premises where George’s accident occurred, who owned the ladder involved in George’s accident, or the degree to which Columbia/HCA controlled safety procedures in place on the premises.
The Hospital did introduce a document titled Columbia/HCA “Employee Guide to Health and Safety” containing a section on safety with ladders, indicating there may have been some direction by the parent over the subsidiary regarding ladder safety. Kenny Gibson, the Hospital’s maintenance supervisor, testified that management communicated to employees the safety concepts in the Columbia/HCA safety guide prior to the Hospital’s promulgating its own safety rules. In summary, based on the record in this case we cannot imply that there would be no purpose in Columbia/HCA’s desire to benefit from a waiver.
Therefore, under the facts of this case, and applying the express negligence rule as well as other rules of contract construction to the waiver agreement, we decline to imply that the drafters of the waiver agreement intended to include the Hospital as a party against whom George waived his common law remedies where the waiver agreement does not expressly so provide. Therefore, we decline the Hospital’s request that we reverse the trial court’s judgment and render judgment in favor of the Hospital. Issue one is overruled.
Ratification, Release, Waiver and Estoppel
Issues two, three, and seven concern the Hospital’s affirmative defenses. - In issues two and three, the Hospital complains that the trial court erred in denying its request to admit evidence it contends raises a fact issue regarding its affirmative defenses, namely, waiver, release, and estoppel. In issue seven, the Hospital complains that the trial court erred in refusing the Hospital’s requested trial amendment to assert ratification as an affirmative defense.
With respect to estoppel, the Hospital argues George’s acceptance of payments, totaling $78,167.24, requires the en- *292 foreement of an agreement (albeit not the one expressly agreed to in the written contract) that George would not sue the Hospital at common law. The Hospital contends that by accepting voluntary payments for medical expenses and lost wages, George ratified the waiver agreement. At the outset, we note that George signed the waiver agreement and never disputed that he was bound by the written terms' of the agreement.
Under Texas law, a tortfeasor may voluntarily pay the person it injures, and the payment cannot then be asserted as an admission that the tortfeasor was negligent.
See
Tex.R. Evid. 409. Therefore, the payments to George for medical and lost wages, and George’s acceptance of them, do not raise evidence sufficient to prohibit George from enforcing the terms of the written agreement. The only case the Hospital cites,
Miller v. Kennedy & Minskew, Prof'l Corp.,
The Hospital also asserts that George ratified the understanding that the Hospital was released. However, the Hospital did not plead its affirmative defense of ratification as required under Rule 94 of the Texas Rules of Civil Procedure. Thus, the Hospital waived its ratification defense.
See Land Title Co. of Dallas, Inc. v. F.M. Stigler, Inc.,
In issue seven, the Hospital asserts the trial court erred in not granting leave for the Hospital to amend its pleadings to assert the ratification defense. A trial court’s order granting or denying a request for a trial amendment is reviewed under an abuse of discretion standard.
State Bar of Texas v. Kilpatrick,
The Hospital indicates that it argued ratification as a defense in support of its Motion for Summary Judgment when it filed its Supplemental Argument and Authority in Support of Its Motion for Summary Judgment on July 16, 2001. The jury trial in this case did not occur until 2004. It is clear from the record that the Hospital was aware of its contention that George’s conduct allegedly resulted in a ratification to waive his claims against the Hospital long before the trial.
When the trial court denies leave to file an amended pleading injecting a
*293
new substantive defense, the burden shifts to the party who offered the amended pleading to clearly demonstrate on appeal that the trial court abused its discretion.
Hardin v. Hardin,
With respect to its waiver and release defenses, the Hospital asserts that George had actual knowledge that by executing the waiver he was waiving negligence claims against the Hospital, and argues that George’s actual knowledge makes the waiver effective to protect the Hospital. For this proposition, the Hospital relies on Reyes, which states that “if both contracting parties have actual knowledge of the plan’s terms, an agreement can be enforced even if the fair notice requirements were not satisfied.”
Reyes,
As discussed above the Hospital’s Bill of Exceptions offered no testimony regarding the Hospital’s understanding of the plan’s terms; instead it offered only George’s testimony about his understanding. The affidavits of Mr. Franck II, and Ms. O’Quin, offered by the Hospital, contain no evidence regarding the Hospital’s understanding of how the waiver applied when the injury arose in the course and scope of an injury to a Hospital employee.
We have held that the contract was not ambiguous, and is therefore construed under the “foui' corners” rule. Although the Hospital attempted to offer George’s understanding of the waiver agreement into evidence, and this evidence was excluded, we note that George’s testimony of his understanding of the waiver agreement would have injected testimony inconsistent with the express terms of the written agreement in violation of the parol evidence rule, which is a rule of substantive law.
When the parties have made an unambiguous written agreement with respect to a particular subject matter, the parol evidence rule prohibits the presentation of extrinsic evidence to vary or contradict the terms of a written instrument.

*294 Error in Jury Selection
In Issue four, the Hospital complains the trial court erred in failing to strike four veniremembers for cause—Ms. Hazleton, Ms. Phillips, Mr. Stevenson, and Mr. Troup. During voir dire, Ms. Hazle-ton indicated that her feelings about all that Mr. George had been through would cause her to “give him money even in a situation where he did not carry the burden of proof that the Court [asked her] to look at.” Ms. Phillips indicated' “I would have trouble not giving him money—something, anyway,” even if George failed to carry his burden of proof. Mr. Stevenson stated that even if the evidence showed no negligence he would not be able to award no money. Mr. Troup stated that he knew Mr. George and Mr. George’s wife, Wendy, and that he did not think that knowing them would cause him to lean either way.
The Hospital’s attorney used four of his peremptory strikes on these venire-members, and used his other two peremptory strikes as well. The Hospital’s attorney requested the trial court allow the Hospital four additional strikes, but the trial court denied the request. At that point, the Hospital’s attorney made a record that had he been allowed four additional strikes, he would have stricken Mr. Richardson, Ms. Goins, Mr. Anders, and Mr. Dausel. Mr. Richardson, Ms. Goins, Mr. Anders and Mr. Dausel joined six of the other jurors in the issues found against the Hospital, resulting in the trial court’s rendering judgment against the Hospital.
The Hospital used all six of its peremptory strikes provided under the rules. Tex.R. Civ. P. 233. There is no requirement that a party identify the reasons the remaining veniremembers that it would have stricken were objectionable.
Cortez v. HCCI-San Antonio, Inc.,
Because the error was preserved, we analyze the information provided by the four veniremembers the trial court refused to strike for cause to evaluate whether any of the four were disqualified to serve as a matter of law. We consider the entire examination, and not just the answers of these four veniremembers that arguably reflect bias.
Cortez,
Under Texas law, a prospective juror who has a bias or prejudice in favor of or against a party is disqualified to serve on the jury.
See
Tex. Gov’t Code Ann. § 62.105(4) (Vernon 1998);
Shepherd v. Ledford,
The purpose of jury selection is “to provide a jury composed of persons who are not biased or prejudiced. The object is an impartial jury.”
Hallett,
689 5.W.2d at 889. Bias has been defined as “an inclination toward one side of an issue rather than to the other, but to disqualify, it must appear that the state of mind of the juror leads to the natural inference that he will not or did not act with impartiality.”
Compton v. Henrie,
In this case, as is true in most trials, many of the jurors expressed their views in response to the lawyers’ questions during voir dire. The trial judge heard the responses of the individual veniremembers and the requests of the lawyers, and disqualified a number of veniremembers who expressed bias. In fact, the trial judge struck fourteen of the veniremembers for cause, and we note that the vast majority of these strikes were at the request of the attorney for the Hospital.
With respect to the venire-members the trial court refused to strike, we imply that the trial court ruled that they were not biased or prejudiced.
Swap Shop v. Fortune,
However, the trial court’s rulings and implicit finding of no disqualification regarding the biases expressed by jurors Hazleton, Phillips, and Stevenson are more troublesome. Hazleton and Stevenson indicated without equivocation that they would favor George in this case with an award even if he failed to prove his case. Hazleton stated in voir dire that she would give Mr. George money even if plaintiff failed to carry his burden of proof. Stevenson acknowledged that if at the end the evidence showed no negligence, he would still not be able to award no money. Ha-zleton and Stevenson’s statements are unequivocal, and there is nothing in the record indicating that either would try to follow the instructions of the trial court.
Phillips, on the other hand, indicated an equivocal bias regarding awarding money despite George’s failure to carry his burden of proof when she acknowledged that she “might have trouble”, and then went further and stated that she “would have trouble not giving him money — something, anyway.” We observe that Phillips’s statements, although subjecting her to the trial court’s discretion to disqualify her for cause, remain susceptible to the interpretation that although she would have trouble reaching a verdict that awarded no mon *296 ey to George, she still had the capacity to follow the instructions and do so if required by the court’s instructions. Phillips’s statements about having “trouble,” although a close question, are not in the same category as the unequivocal statements of Hazleton and Stevenson.
We hold that Hazleton and Stevenson expressed an unequivocal bias in George’s favor because both tacitly indicated they would disregard instructions by the trial court on the burden of proof, and there was no indication that they would try to follow the trial court’s instructions. The trial court had no discretion to refuse to strike them for cause.
See Shepherd,
With respect to veniremember Phillips, it was within the trial court’s discretion to leave her on the jury on the record made of her potential bias in this case. The trial court did not err in denying the Hospital’s request to strike her. '
See Glenn v. Abrams/Williams Bros.,
Our holding under the voir dire conducted in this case is distinguished from those conducted in Cortez, Goode, and Swap Shop in that the veniremembers in these cases stated they could set their views aside and decide the cases based upon the evidence presented them. No similar inquiry occurred in the voir dire under review here.
Harm is presumed where other objectionable jurors made the jury by virtue of the failure to strike the disqualified jurors.
Cortez,
Damages Submission
In issue five and six, the Hospital complains that the trial court gave the jury a global charge that segregated only the past from the future damages, and failed to segregate certain future damages such as future medical expenses from other future damages such as future pain and suffering. In addition, the Hospital complains that the damage award was excessive. In light of our ruling on issue four, we need not reach issues five or six. 5
Accordingly, we reverse the trial court’s judgment and remand this cause for proceedings consistent with this opinion.
REVERSED AND REMANDED.
Notes
. Approximately $78,000 in plan benefits were paid to George as a result of his injuries.
. The conspicuousness requirement is not an issue in this case.
. We observe that, in the trial court and on appeal, George never denied or disputed that he signed the written agreement or that he was bound by its terms. Rather, the dispute at trial and on appeal is whether the waiver George signed protects both the Hospital and Columbia/HCA.
. We further note that
Reyes
is distinguishable from this case. In
Reyes,
the employer contested the application of the fair notice requirements, but also conceded that if the conspicuousness requirement applied, then the waiver signed by the employee was inconspicuous. The appellate court remanded the cause for a fact determination of whether the employee had actual knowledge of the terms of the plan.
Reyes,
. Nevertheless, we note that Texas Rule of Appellate Procedure 44.1(a)(2) allows an appellate court to reverse where the trial court's error "probably prevented the appellant from properly presenting the case to the court of appeals.” Id. The Texas Pattern Jury Charge states:
Broad-form submission of multiple elements of damages may lead to harmful error if there is a proper objection raising insufficiency of the evidence to support one or more of the elements submitted. Harris County v. Smith,96 S.W.3d 230 (Tex.2002). If there is any question about the sufficiency of the evidence to support one or more of the elements, the Committee recommends that the elements of damages be separately submitted....
Comm. On Pattern Jury Charges, State Bar Of Tex., Texas Pattern Jury Charges-General Negligence PJC 8.2 cmt. (2003) (emphasis added). “[Ajsking the jury to record its verdict as to each element of damages when there is doubt as to the legal sufficiency of the evidence will permit the losing party to preserve error without complicating the charge or the jury’s deliberations.”
