    COURT OF APPEALS
    THIRTEENTH DISTRICT OF TEXAS
    CORPUS CHRISTI - EDINBURG
    NATIONAL UNION FIRE INSURANCE
    COMPANY OF PITTSBURGH, PA
    AND INDUSTRIAL RISK INSURERS,                                             Appellants,
    v.
    JOHN ZINK COMPANY; FISHER
    CONTROLS COMPANY, INC.; FISHER
    CONTROLS INTERNATIONAL, INC.;
    FISHER CONTROLS INSTALLATION AND
    SERVICE COMPANY; AND VALTEK, INC.,                                         Appellees.
    On appeal from the 117th District Court
    of Nueces County, Texas.
    MEMORANDUM OPINION
    Before Justices Yañez, Garza and Benavides
    Memorandum Opinion by Justice Benavides
    This litigation arises out of an explosion that occurred in 1984 and a fire that
    occurred in 1985 at a refinery operated by Valero Energy Corporation (“Valero”) in Corpus
    Christi, Texas. Appellants, National Union Fire Insurance Company of Pittsburgh, PA and
    Industrial Risk Insurers (collectively “the Insurers”), appeal the trial court’s order granting
    final summary judgment in favor of appellees, John Zink Company (“Zink”), Valtek, Inc.,
    and three entities we will collectively refer to as “Fisher”: Fisher Controls Company, Inc.,
    Fisher Controls International, Inc., and Fisher Controls Installation and Service Company
    (collectively the “Contractors”). By a single issue, which includes numerous subparts, the
    Insurers argue that the trial court erred in granting all the Contractors’ motions for
    traditional summary judgment on their affirmative defenses of release and waiver of liability
    arising from a contract between Valero and M.W. Kellogg Construction Company
    (“Kellogg”). The Insurers’ arguments can be generally summarized as follows: (1) the
    Contractors are not “subcontractors” as required by the release and waiver provisions; (2)
    if the Contractors are subcontractors, the release and waiver provisions are invalid under
    the express negligence doctrine; (3) the release and waiver provisions do not apply to
    claims based on the previously signed purchase orders and, in any event, are invalid under
    the Texas Deceptive Trade Practices Act (“DTPA”) provisions in effect at the time of the
    purchase orders; (4) if the release and waiver provisions are valid, they are limited, and
    therefore, the trial court erred by granting final summary judgment; and (5) various
    preclusion doctrines do not bind this Court to its prior rulings in related appellate decisions.
    We affirm.
    I. BACKGROUND
    This litigation, in various forms and fashions with different parties at times, has been
    reviewed by this Court on three different occasions. See generally Valero Energy Corp.
    v. M.W. Kellogg Constr. Co., 
    866 S.W.2d 252
    (Tex. App.–Corpus Christi 1993, writ denied)
    (Valero); Nat’l Union Fire Ins. Co. v. John Zink Co., 
    972 S.W.2d 839
    (Tex. App.–Corpus
    2
    Christi 1998, pet. denied) (Nat’l Union I); Nat’l Union Fire Ins. Co. v. John Zink Co., No. 13-
    02-00446-CV, 
    2005 WL 608229
    (Tex. App.–Corpus Christi Mar. 17, 2005, pet. denied)
    (mem. op.) (Nat’l Union II). We will begin by describing the relationship of the parties and
    the underlying events leading to litigation. We will then discuss the procedural history,
    including Valero, Nat’l Union I, and Nat’l Union II. Finally, we will discuss the proceedings
    leading to the instant appeal and the parties’ arguments.
    A.      Valero
    In July 1979, Saber Energy, Inc. (now Valero) began negotiating with Kellogg for
    construction, engineering, and design services related to a $500 million expansion of
    Valero’s Corpus Christi oil refinery. 
    Valero, 866 S.W.2d at 254
    .                     Kellogg engaged
    subcontractors and began construction on the project on October 15, 1980, but the final
    contract between Valero and Kellogg was not executed until May 28, 1982 (the
    “Valero/Kellogg contract”). 
    Id. The Valero/Kellogg
    contract was made retroactive to
    October 15, 1980, when construction began. 
    Id. at 257.
    The Valero/Kellogg contract provided for certain releases, waivers, and indemnity
    between the parties and for various types of insurance coverage:
    6.2     [Kellogg]1 shall provide the following insurance:
    ....
    (b).    Comprehensive General Liability Insurance (including
    Contractual Liability, Contractor’s Contingent Liability and
    Explosion, Collapse and Underground Damage) covering
    Bodily Injury and Property Damage with a Combined Single
    Limit of $2,000,000 per occurrence. . . . [Kellogg’s] liability with
    respect to [Valero’s] property so covered shall be limited to the
    amount of such insurance.
    1
    The contract refers to Kellogg as “Contractor” and Valero as “Owner.” The term “Contractor” does
    not include Kellogg’s subcontractors in its definition within the contract.
    3
    ....
    6.3    [Kellogg’s] subcontractors will be required to carry insurance of the
    types described in . . . paragraph 6.2 above, as appropriate, at limits
    considered adequate in accordance with [Kellogg’s] standard
    subcontract procedures.
    ....
    6.7    [Kellogg] agrees that it will defend, indemnify, and hold [Valero]
    harmless against all claims, liability, loss and expense including legal
    fees and court costs in connection therewith, arising out of this
    agreement or the work to be performed hereunder, to the extent
    [Kellogg] is compensated by insurance required by this Agreement.
    6.8    [Valero] shall release, defend, indemnify and hold harmless [Kellogg],
    its subcontractors and affiliates and their employees performing
    services under this Agreement against all claims, liabilities, loss or
    expense, including legal fees and court costs in connection therewith,
    arising out of or in connection with this Agreement or the Work to be
    performed hereunder, including losses attributable to [Kellogg’s]
    negligence, to the extent [Kellogg] is not compensated by insurance
    carried under this ARTICLE. [Valero] shall obtain for the benefit of
    [Kellogg], its subcontractors and affiliates and their employees, waiver
    of subrogation rights under all its applicable insurance policies.
    6.9    Neither [Kellogg] nor its affiliates nor its subcontractors or vendors,
    either individually or jointly shall be liable to [Valero] or its affiliates,
    irrespective of whether alleged to be due to negligence or otherwise,
    for loss of anticipated or non-operation of the Plant or other
    equipment, for loss of catalysts or chemicals or for any consequential
    or special loss or damage arising from any reason whatsoever.
    The Insurers allege that on July 13, 1984, a vertical air preheater exploded and
    caused damage to the plant. Nat’l Union 
    I, 972 S.W.2d at 841
    . On May 27, 1985, a fire
    occurred in a citrate scrubber stack at the Corpus Christi Valero plant. 
    Id. As noted
    above, part of the discussions prior to the Valero/Kellogg contract involved
    negotiations for mutual insurance coverage for events at the refinery. Nat’l Union 
    I, 972 S.W.2d at 841
    . Valero’s Insurers, appellants in this case, paid insurance benefits to Valero
    for the claims arising from the citrate scrubber stack fire. 
    Id. 4 Valero
    brought a lawsuit against Kellogg and Ingersoll-Rand. 
    Valero, 866 S.W.2d at 254
    . Additionally, the Insurers brought two lawsuits against the Contractors2 and also
    intervened in Valero’s lawsuit. Nat’l Union 
    I, 972 S.W.2d at 842
    . All of these cases were
    then consolidated. 
    Id. Against the
    Contractors, the Insurers alleged subrogation claims for products liability
    and negligence related to the manufacture and installation of the products, breach of
    contract, and breach of an agreement to indemnify Valero through insurance obtained to
    cover the alleged losses. See 
    id. Additionally, the
    Insurers alleged that the Contractors
    breached a fiduciary duty, breached a duty of good faith and fair dealing, and violated the
    Texas Insurance Code and the DTPA by failing to procure insurance. 
    Id. Kellogg and
    Ingersoll-Rand filed traditional motions for summary judgment based
    on the waiver and release provisions in the Valero/Kellogg contract quoted above. 
    Valero, 866 S.W.2d at 254
    . After the motions were filed, Valero amended its petition to assert
    various defenses to the waiver and release provisions, including fraud, unconscionability,
    duress, unenforceability, and public policy. 
    Id. Valero filed
    a motion for partial summary
    judgment based on this amended pleading, but as a sanction, the trial court struck all
    pleadings, affidavits, and exhibits with respect to the defenses of fraud, unconscionability,
    duress, and adhesion. 
    Id. The trial
    court then granted Kellogg and Ingersoll-Rand’s
    motions for summary judgment and denied Valero’s motion for partial summary judgment.
    
    Id. The Insurers’
    claims were severed into a separate lawsuit, which became the basis for
    Nat’l Union I, and the severed suit was abated pending Valero’s appeal of the summary
    judgments. Nat’l Union 
    I, 972 S.W.2d at 842
    .
    2
    The Insurers also sued Puffer Sweiven, Inc., Puffer-Sweiven Trading Corporation, and Puffer-
    Sweiven Texas, Inc., who are not parties to this appeal.
    5
    On appeal, we initially upheld the sanctions against Valero. See 
    Valero, 866 S.W.2d at 255-56
    . We then addressed the summary judgment rulings. 
    Id. at 256.
    First,
    we rejected Valero’s defenses to enforcement of the waiver and release provisions of the
    contract, holding that the provisions did not violate public policy and that the parties validly
    bargained for the provisions. 
    Id. at 257-58.
    Second, we held that Ingersoll-Rand was also entitled to protection under the waiver
    and release provisions as Kellogg’s subcontractor:
    Similarly, Ingersoll-Rand, as one of Kellogg’s subcontractors, is also
    addressed in the Valero/Kellogg contract as an entity entitled to protection
    under the waiver and hold-harmless clauses. As such, it, too is held
    harmless as [and] is indemnified under the contract fairly negotiated between
    Kellogg and Valero.
    
    Id. at 258.
    Finally, we rejected Valero’s argument that it did not validly waive its claims
    under the DTPA, which required us to determine which version of the Act applied to the
    claims. 
    Id. at 258-59.
    Because we rejected all of Valero’s arguments on appeal, we
    affirmed the summary judgment in favor of Kellogg and Ingersoll-Rand. 
    Id. at 259.
    B.     Nat’l Union I
    After Valero, the trial court allowed the Insurers to proceed against the Contractors.
    Nat’l Union 
    I, 972 S.W.2d at 842
    . The Contractors filed motions for summary judgment,
    claiming that the Insurers’ “wholly derivative claims had been eliminated when [this Court]
    found in Valero that, under the terms of the contract, Valero had waived all of its claims
    against Kellogg and its subcontractors.” 
    Id. Additionally, the
    Contractors argued that the
    Insurers were bound by Valero under the “law of the case” doctrine; specifically, the
    Contractors argued that, because we previously found that Valero waived all its claims
    against Kellogg’s subcontractors under the Valero/Kellogg contract, the Insurers had no
    claims against the Contractors. 
    Id. The trial
    court granted the motions for summary
    6
    judgment. 
    Id. at 841.
    On appeal, we agreed with the Contractors that the Insurers’ claims were wholly
    derivative of Valero’s claims. 
    Id. at 843.
    Thus, we concluded that we needed to “review
    our holding in Valero and the motions for summary judgment in that case” to “adequately
    assess [the Contractors’] wholly derivative argument.” 
    Id. at 844.
    We noted that in Valero,
    Kellogg and Ingersoll-Rand “moved for summary judgment on the ground that, under the
    terms of the contract, Valero had agreed to exculpate and indemnify Kellogg and its
    subcontractors for any liabilities.” 
    Id. (footnote omitted).
    We referred to sections 6.8 and
    6.9 of the Valero/Kellogg contract. 
    Id. We noted,
    however, that Kellogg’s motion for
    summary judgment in Valero also stated that “[u]nder the [Valero/Kellogg contract],
    insurance was established as the exclusive remedy for any liability.” 
    Id. Thus, we
    reviewed sections 6.2(b), 6.3, and 6.7 of the contract. 
    Id. We further
    noted that the
    Contractors did not assert in their motion for summary judgment that Valero waived its
    insurance claims or that Valero was asserting insurance claims in its lawsuit. 
    Id. Thus, we
    held that the Contractors read Valero too broadly:
    In [Valero], we were asked to consider whether Valero contractually
    waived its claims for gross negligence and products liability. Specifically,
    Valero argued that a waiver of gross negligence claims offended public
    policy and that a general waiver of liability was not sufficient to waive
    products liability causes of action. After setting forth section 6.8 of the
    contract, stating that Valero held harmless Kellogg and its subcontractors
    “against all claims . . . to the extent CONTRACTOR is not compensated by
    insurance[,]” we held that Kellogg and Ingersoll-Rand were absolved “of all
    liability sounding in products liability and gross negligence.”
    Nowhere in the opinion did we specifically hold that all of Valero’s
    liability claims were waived by the contract. Moreover, we could not so hold
    because Valero’s insurance claims were not expressly addressed by the
    motion for summary judgment and, therefore, were not before the trial court
    or this Court. To the extent that [Valero] may be interpreted to hold that all
    of Valero’s claims were waived by the contract, we hold that the waiver must
    be limited because of our reliance on sections 6.8 and 6.9 of the agreement.
    7
    In other words, Valero agreed to absolve Kellogg and its subcontractors of
    liability for claims to the extent the contractor was not compensated by
    insurance and for those losses specified in section 6.9.
    Although the Insurers’ claims are wholly derivative of Valero’s, they
    seek recovery for insurance claims Valero may have against [the
    Contractors]. As is evidenced from contract provisions 6.2, 6.3, and 6.7, the
    contract required liability insurance and regulated its applicability. Whether
    Valero has insurance claims against [the Contractors], subrogation rights,
    and [the Contractors’] status under the terms of the contract are some issues
    that have not been addressed by any motion for summary judgment. Thus,
    if the trial court granted summary judgment in favor of [the Contractors] on
    the ground that, pursuant to [Valero], all of the Insurers’ wholly derivative
    claims were waived by the terms of the contract, we conclude the court
    committed error.
    
    Id. at 845
    (citations omitted). Thus, we held that Valero did not preclude the Insurers from
    asserting insurance claims against the Contractors because that issue was not before us
    in Valero. 
    Id. Next, we
    addressed the Contractors’ argument that Valero was the law of the case,
    which we noted “essentially reassert[ed] the arguments expressed in the first ground.” 
    Id. We explained
    that the law-of-the-case doctrine “does not necessarily apply if the issues
    and facts are not substantially the same in the subsequent trial.” 
    Id. We then
    held that
    Nat’l Union I was not the “same case as or a subsequent stage of Valero, nor [were] the
    issues the same.” 
    Id. Thus, we
    held that if the trial court based its summary judgment on
    the law-of-the-case doctrine, it was in error. 
    Id. We further
    held that res judicata and collateral estoppel did not bar litigation of the
    issues involved in Nat’l Union I:
    The motion for summary judgment in [Valero] was filed by the
    defendants, Kellogg and Ingersoll-Rand, who agreed that the Insurers’
    claims were not a part of the motion. [The Contractors] apparently did not
    object to the agreement and were not parties to the motion. Thus, the
    present parties were not cast as adversaries in the previous summary
    judgment. In addition, the liability facts in this case have never been fully
    8
    litigated, nor were those facts essential to the summary judgment in [Valero].
    Moreover, the issue of whether insurance claims exist under the terms of the
    contract was not litigated. If the trial court granted summary judgment in
    favor of [the Contractors] on the grounds of res judicata or collateral
    estoppel, we conclude the court committed error.
    
    Id. at 846.
    After rejecting limitations and judicial estoppel arguments made by the Contractors,
    we turned to Zink’s arguments specific to the claims against it. 
    Id. at 847.
    Zink argued that
    it was entitled to summary judgment under a contract it had with Kellogg. 
    Id. We noted
    that Zink’s motion reiterated that the Insurers’ claims can be no greater than Valero’s, and
    that the motion stated: “Valero’s claims, which have been dismissed with prejudice as to
    John Zink, were for consequential damages, and the Kellogg/John Zink agreement
    expressly states that John Zink shall not be liable for such consequential damages.” 
    Id. We explained
    that Zink relied on a purchase order, bearing Zink’s “Standard Terms of
    Sale,” and that it appeared to exclude Zink’s liability for consequential damages. 
    Id. However, we
    found no evidence that Valero was bound to that agreement or that Valero’s
    claims against Zink were dismissed because of that agreement because “the motion for
    dismissal and the dismissal order [were] neither attached to nor referenced in the motion
    for summary judgment.” 
    Id. Thus, Zink
    failed to establish that the Insurers were bound by
    that agreement, and the trial court erred to the extent it granted summary judgment on that
    ground. 
    Id. Because we
    sustained the Insurers’ issues, we reversed the summary
    judgments and remanded. 
    Id. at 848.
    The Texas Supreme Court denied review.
    C. Nat’l Union II
    On remand after Nat’l Union I, the Contractors filed another round of traditional
    motions for summary judgment, which the trial court again granted. Nat’l Union II, 2005
    
    9 WL 608229
    , at *1. On appeal, we summarized the status of the litigation up to that point:
    The previous decision from this Court stemming from the same
    underlying litigation, [Nat’l Union I], held that because Valero’s insurance
    claims against [the Contractors] were not expressly addressed by [the
    Contractors]’ motions for summary judgment, the trial court erred by granting
    complete relief to [the Contractors]. In particular, [the Contractors] had failed
    to explain whether [the Insurers] had asserted any independent claims
    against them apart from their liability to Valero, whether they should be
    treated as sub-contractors under the Valero-Kellogg contract, and why the
    waiver of liability in the Valero-Kellogg contract should trump the individual
    waivers of liability in the Zink and Fisher purchase orders. In response, [the
    Contractors] amended and re-asserted their motions for summary judgment,
    this time addressing Valero’s insurance claims, subrogation rights and status
    under the terms of the contract. The trial court subsequently granted these
    motions.
    [The Insurers’] seventh amended petition does not assert independent
    claims that arise from [the Insurers’] own status, but rather only asserts that
    [the Contractors] breached duties owed to Valero, which they now assert on
    Valero’s behalf as its insurers. Therefore, we can appropriately apply the
    previous decisions from this Court that address the liability of Valero under
    its contract with Kellogg.
    
    Id. at *3.
    The Insurers first argued that the summary judgment failed to address claims
    against Zink and Fisher3 that were raised in their seventh amended petition, which was
    filed after the Contractors moved for summary judgment. 
    Id. at *2.
    Specifically, the
    Insurers added claims for breach of contract and breach of guarantees and warranties
    against Zink and claims for breach of guarantees and warranties and reformation against
    Fisher. 
    Id. We held
    that the trial court erred to the extent it granted summary judgment
    on the newly-filed claims, as those claims were not properly before it as part of the
    summary judgment proceeding. 
    Id. Thus, we
    reversed and remanded as to those claims.
    3
    W e noted that the late-added claim s were not asserted against Valtek. Nat’l Union Fire Ins. Co. v.
    John Zink Co., No. 13-02-00446-CV, 2005 W L 608229, at *2 n.2 (Tex. App.–Corpus Christi Mar. 17, 2005,
    pet. denied) (m em . op.) (Nat’l Union II).
    10
    
    Id. Next, we
    noted that the Insurers claimed negligence, products liability, and breach
    of contract. 
    Id. at *4.
    We addressed the Insurers’ argument that the Contractors never
    provided evidence that they were Kellogg’s “subcontractors” and, therefore, entitled to
    assert affirmative defenses arising from the Valero/Kellogg contract. 
    Id. We referred
    to
    sections 6.8 and 6.9 of the Valero/Kellogg contract, which we noted “on [their] face
    absolve[] Kellogg and its sub-contractors from all liability against ‘all claims’ beyond what
    is covered by Kellogg’s own insurance.” 
    Id. After quoting
    at length from Valero, we held
    that “the issue of sub-contractor liability under the Valero-Kellogg contract has been
    previously decided by this Court.” 
    Id. We held
    that because the Insurers’ claims were
    derivative of Valero’s claims against Kellogg’s subcontractors, the Insurers were estopped
    from asserting the claims that Valero validly waived in its contract with Kellogg. 
    Id. We held
    that the only remaining issue was whether the Contractors had proved that they were
    “subcontractors” entitled to the benefit of the release and waiver provisions. 
    Id. Initially, we
    defined “subcontractor” as “a party who takes and performs a portion of
    a contract from a principal contractor or who enters into a contract for the performance of
    an act with a person who has already contracted for its performance.” 
    Id. at *5.
    We then
    held that Zink provided substantial documentation establishing its subcontractor status,
    including “its bid to provide the air heater, and Kellogg’s subsequent acceptance of the bid
    in a purchase order.” 
    Id. We likewise
    found that Fisher provided substantial evidence,
    including: an “inquiry” from Kellogg regarding the computer control system, a bid from
    Fisher in response, and acceptance of the bid from Kellogg in the form of a purchase
    order. 
    Id. We opined
    that the evidence established that Zink and Fisher contracted with
    11
    Kellogg to perform work that Kellogg had already contracted to perform for Valero, bringing
    both within the definition of a subcontractor. 
    Id. Thus, we
    held that the trial court did not
    err by granting Zink and Fisher’s motion for summary judgment on these grounds. 
    Id. The Insurers
    rejoined by arguing that Zink and Fisher were liable to Kellogg and
    Valero for a breach of warranties and guarantees in their purchase orders, signed in June
    1981 before the Valero/Kellogg contract was finalized, which stated that they would
    “defend and hold [Kellogg and Valero] harmless . . . . for loss of and/or damage to property
    caused in whole or in party [sic] by the negligence or willful acts of [Zink and Fisher] in
    connection with the Materials furnished hereunder, including without limitation, the
    installation, erection, repair, adjustment or operation thereof.” 
    Id. We rejected
    this
    argument, stating that the later-signed Valero/Kellogg contract was a valid, integrated
    agreement which preempted the prior, inconsistent purchase orders under the parol
    evidence rule. 
    Id. We then
    turned to Valtek’s evidence. 
    Id. at *6.
    We held that Valtek had not raised
    its subcontractor status as a ground for summary judgment:
    The evidence Valtek produced in support of its motion for summary judgment
    focuses only on the testing and reliability of the valve involved in the refinery
    incidents. Valtek is seeking to absolve itself of liability by demonstrating not
    that it was a subcontractor but rather that it was not negligent and its valve
    was not defective. In all of Valtek’s summary judgment evidence, Kellogg is
    only mentioned in a reply to an interrogatory from [the Insurers]: “the valve
    met the requirements supplied by [Kellogg] for the designated service.” The
    other [Contractors] provided signed agreements, invoices and purchase
    orders demonstrating an offer and acceptance occurred between themselves
    and Kellogg. Valtek, beyond bare assertions in its motion for summary
    judgment, did not provide any evidence to indicate that it had a business
    relationship with Kellogg such that it could be considered Kellogg’s
    subcontractor for purposes of the Valero-Kellogg project.
    
    Id. Thus, we
    held that Valtek did not prove that it was entitled to rely on the waiver
    12
    provisions in the Valero/Kellogg contract, and we reversed the trial court’s summary
    judgment in Valtek’s favor. In sum, we affirmed the summary judgment as to Zink and
    Fisher, except with respect to the claims added after the motions for summary judgment
    were filed, and we reversed the summary judgment as to Valtek. 
    Id. The Texas
    Supreme
    Court again denied review.
    D.      On Remand After Nat’l Union II
    On remand, the Insurers filed their tenth amended petition, in which they alleged the
    following claims against the Contractors: (1) breach of the Fisher/Kellogg purchase order;
    (2) breach of contract-based warranties arising out of the Fisher/Kellogg purchase order;
    (3) breach of pre-sale implied warranties; (4) breach of the duty to adequately warn and
    instruct; (4) products liability; (5) post-sale negligent misrepresentation; (6) breach of post-
    sale implied warranties; (7) negligence; (8) gross negligence; (9) DTPA violations; and (10)
    breach of the Valero/Kellogg contract.
    The Contractors again moved for final summary judgment on the claims. Fisher
    moved for summary judgment, and filed an amended motion for summary judgment,
    arguing that all of the Insurers’ claims were barred by the waiver and release provisions in
    the Valero/Kellogg contract and by this Court’s prior decisions. Initially, Fisher argued that
    some of the claims pleaded in the Insurers’ tenth amended petition were previously
    adjudicated by this Court in Nat’l Union II but had nevertheless been repleaded by the
    Insurers.4 Nevertheless, Fisher argued that all of the Insurers’ claims failed as a matter of
    4
    Specifically, Fisher argued that this Court’s affirm ance of the sum m ary judgm ent in Nat’l Union II
    precluded the Insurers from re-asserting the following claim s: (1) negligence; (2) gross negligence; (3)
    products defect/liability; (4) m isrepresentations; (5) breach of im plied warranties; (6) breach of the duty to
    adequately warn and instruct; (7) breach of sections 6.2(b), 6.3, and 6.7 of the Valero/Kellogg contract; (8)
    breach of article 21.21 of the Texas Insurance Code; and (9) DTPA violations.
    13
    law under the law-of-the-case doctrine and Nat’l Union II because: (1) Valero expressly
    released and waived any and all claims against Kellogg’s subcontractors, including Fisher,
    when it executed the Valero/Kellogg contract; (2) Fisher was Kellogg’s subcontractor in the
    Valero refinery expansion project; (3) as Valero’s subrogees, the Insurers are bound by
    Valero’s release; (4) the liability provisions contained within the Fisher subcontract with
    Kellogg were preempted and waived by Valero when it subsequently executed the
    Valero/Kellogg contract; and (5) the trial court did not err when it granted Fisher’s summary
    judgment on the claims raised in the Insurers’ sixth amended petition, as decided by Nat’l
    Union II. Fisher again submitted the same evidence it presented in the prior, affirmed
    summary judgment proceeding and argued that, as in Nat’l Union II, this evidence
    conclusively established that Fisher was Kellogg’s subcontractor, entitling Fisher to rely on
    the release and waiver provision in the Valero/Kellogg contract as a defense to all the
    Insurers’ claims. Finally, Fisher argued that, as this Court held in Valero, Valero’s waiver
    of DTPA claims was valid. Zink also filed a new motion for summary judgment on remand,
    followed by an amended motion for summary judgment, making the same arguments as
    Fisher and also attaching the same evidence upon which it had previously relied to show
    its subcontractor status.
    Valtek also filed a motion for summary judgment, followed by a supplemental motion
    for summary judgment, arguing that it was a subcontractor entitled to the waiver and
    release provisions in the Valero/Kellogg contract. In support, Valtek submitted evidence
    showing that Kellogg submitted an inquiry to Valtek regarding expander bypass valves it
    manufactured. On August 14, 1981, Valtek submitted to Kellogg a proposal for the valves,
    noting that it was bidding in accordance with Kellogg’s specifications. On that same day,
    14
    Valtek also issued a bid and quote to Kellogg. On September 23, 1981, Valtek agreed to
    Kellogg’s terms and conditions and continued corresponding with Kellogg regarding the
    valve specifications. Kellogg then issued a purchase order to Valtek on November 16,
    1981. On December 4, 1981, Valtek prepared a certified valve order. Valtek argued that
    this evidence was identical to that submitted by Fisher and Zink, which was found by this
    Court in Nat’l Union II to conclusively establish subcontractor status and entitlement to the
    release and waiver provisions in the Valero/Kellogg contract.
    The Insurers responded to the Contractors’ motions for summary judgment and also
    filed a motion for partial summary judgment on the Contractors’ affirmative defenses,
    arguing that their claims were not barred by the law-of-the-case doctrine, res judicata, or
    collateral estoppel.    Next, the Insurers argued that the Contractors were not
    “subcontractors” entitled to rely on the release and waiver provisions in the Valero/Kellogg
    contract because: (1) the evidence established that the Contractors were merely sellers
    or vendors and did not perform services, as required by the contract to be considered
    subcontractors; (2) the Valero/Kellogg contract allowed Kellogg to hire subcontractors only
    with Valero’s consent, and there was no evidence that Valero consented; and (3) the
    Valero/Kellogg contract required subcontractors to purchase insurance, and there was no
    evidence that the Contractors purchased such insurance.
    In the alternative, the Insurers argued that, even if the Contractors could be
    considered “subcontractors,” the release and waiver was invalid because it did not satisfy
    the “express negligence” test. Furthermore, the Insurers argued that some of their claims
    were based on the Contractors’ purchase orders with Kellogg, which were independently
    viable and which required the Contractors to compensate Valero "for loss of and/or
    15
    damage to property caused in whole or in part by the negligence or willful acts of [the
    Contractors] in connection with the materials furnished hereunder, including without
    limitation, the installation, erection, repair, adjustment or operation thereof.” Additionally,
    the Insurers claimed that the DTPA in effect at the time of the purchase orders did not
    allow a consumer to waive its rights; thus, the DTPA claims arising from the purchase
    orders had not been validly waived. Finally, the Insurers argued that there was no
    evidence that the Insurers’ claims exceeded the limits of Kellogg’s insurance policies,
    which was a necessary precondition to the release and waiver provisions.
    The trial court again granted the Contractors’ motions for final summary judgment
    and denied the Insurers’ motion for partial summary judgment. This appeal ensued.
    II. STANDARD OF REVIEW
    The trial court’s order granting the Contractors’ motion for summary judgment did
    not state the grounds for its rulings. Under these circumstances, we must affirm the
    judgment if any of the grounds alleged in the motions were meritorious. W. Invs., Inc. v.
    Urena, 
    162 S.W.3d 547
    , 550 (Tex. 2005). We review the trial court’s grant of a traditional
    motion for summary judgment de novo. See Provident Life & Accident Ins. Co. v. Knott,
    
    128 S.W.3d 211
    , 215 (Tex. 2003); Branton v. Wood, 
    100 S.W.3d 645
    , 646 (Tex.
    App.–Corpus Christi 2003, no pet.). When reviewing a traditional summary judgment, we
    must determine whether the movant met its burden to establish that no genuine issue of
    material fact exists and that the movant is entitled to judgment as a matter of law. TEX . R.
    CIV. P. 166a(c); Sw. Elec. Power Co. v. Grant,

    Houston v. Clear Creek Basin Auth., 
    589 S.W.2d 671
    , 678 (Tex. 1979). The movant bears
    the burden of proof in a traditional motion for summary judgment, and all doubts about the
    16
    existence of a genuine issue of material fact are resolved against the movant. See Sw.
    Elec. Power 
    Co., 73 S.W.3d at 215
    . We take as true all evidence favorable to the
    nonmovant, and we indulge every reasonable inference and resolve any doubts in the
    nonmovant’s favor. Valence Operating Co. v. Dorsett, 
    164 S.W.3d 656
    , 661 (Tex. 2005).
    We will affirm a traditional summary judgment only if the record establishes that the
    movant has conclusively proved its defense as a matter of law or if the movant has
    negated at least one essential element of the plaintiff’s cause of action. IHS Cedars
    Treatment Ctr. of DeSoto, Tex., Inc. v. Mason, 
    143 S.W.3d 794

    , 425 (Tex. 1997); Clear Creek 
    Basin, 589 S.W.2d at 678

    conclusion to be drawn from the evidence. City of Keller v. Wilson, 
    168 S.W.3d 802
    , 816
    (Tex. 2005). Only when the movant has produced sufficient evidence to establish its right
    to summary judgment does the burden shift to the plaintiff to come forward with competent
    controverting evidence raising a genuine issue of material fact with regard to the element
    challenged by the defendant. Rhone-Poulenc, Inc. v. Steel,

    1999); see Centeq Realty, Inc. v. Siegler, 
    899 S.W.2d 195
    , 197 (Tex. 1995).
    III. SUBCONTRACTOR STATUS
    The Insurers argue that the Contractors do not qualify as “subcontractors” under the
    Valero/Kellogg contract and, therefore, are not entitled to rely on the release and waiver
    provisions, for the following reasons: (1) the “law of the case” doctrine does not preclude
    this Court from revisiting our prior holdings and, in any event, does not apply to the claims
    that survived Nat’l Union II and that were newly pleaded on remand; (2) Fisher’s evidence
    does not show a contract with Kellogg or distinguish between the three Fisher entities in
    17
    a manner that shows exactly which Fisher companies contracted with Kellogg, if any; (3)
    the evidence established that the Contractors were merely vendors or sellers and did not
    perform services, as required by the contract to be considered subcontractors; (4) the
    Valero/Kellogg contract allowed Kellogg to hire subcontractors only with Valero’s consent,
    and there was no evidence that Valero consented; and (5) the Valero/Kellogg contract
    required subcontractors to purchase insurance, and there was no evidence that the
    Contractors purchased such insurance. We address each argument in turn.
    A.        Law of the Case—Fisher and Zink
    In Nat’l Union II, we affirmed the summary judgment in favor of Fisher and Zink,
    holding that they established that they were Kellogg’s subcontractors as a matter of law.
    Nat’l Union II, 
    2005 WL 608229
    , at *5. We remanded, however, for consideration of claims
    the Insurers filed after the Contractors’ motions for summary judgment were filed. 
    Id. at *7.
    The parties appear to dispute what survived Nat’l Union II and what was newly pleaded
    on remand. Because of our disposition, which we explain below, we need not decide this
    issue.
    In Nat’l Union II, we defined “subcontractor” as “a party who takes and performs a
    portion of a contract from a principal contractor or who enters into a contract for the
    performance of an act with a person who has already contracted for its performance.” 
    Id. at *5.
    5        We then held that Zink provided substantial documentation establishing its
    subcontractor status, including “its bid to provide the air heater, and Kellogg’s subsequent
    acceptance of the bid in a purchase order.” 
    Id. We likewise
    found that Fisher provided
    substantial evidence, including an “inquiry” from Kellogg regarding the computer control
    5
    The Insurers do not dispute that this is the appropriate definition of a subcontractor.
    18
    system, a bid from Fisher in response, and acceptance of the bid from Kellogg in the form
    of a purchase order. 
    Id. We opined
    that the evidence established that Zink and Fisher
    contracted with Kellogg to perform work that Kellogg had already contracted to perform for
    Valero, bringing both within the definition of a subcontractor. 
    Id. Thus, we
    held that the
    trial court did not err by granting Zink and Fisher’s motion for summary judgment on these
    grounds. 
    Id. The Insurers
    argue that this Court is not bound to follow its prior decisions in Valero,
    Nat’l Union I, and Nat’l Union II and that we have discretion to reexamine Fisher and Zink’s
    status as Kellogg subcontractors with regard to all the Insurers’ claims, including those
    finally determined by Nat’l Union II.6 Specifically, the Insurers argue that the “law of the
    case” doctrine only binds intermediate courts to follow holdings of a court of last resort.
    Zink and Fisher argue that, at least as to the claims determined in Nat’l Union II, the trial
    court was not free to reexamine those claims and was bound to determine the newly-
    pleaded claims the same way because the defenses raised were the same as those
    decided in Nat’l Union II.
    “The ‘law of the case’ doctrine provides that a decision of a court of last resort on
    a question of law will govern a case throughout its subsequent stages.” City of Houston
    v. Jackson, 
    192 S.W.3d 764
    , 769 (Tex. 2006). Conclusions of law by an intermediate court
    of appeals do not bar reconsideration of the conclusions in a subsequent appeal, but
    rather, the court of appeals retains discretion to revisit the issues depending on the
    circumstances of the case. 
    Id. By narrowing
    the issues in successive stages of the
    6
    As Fisher points out, on rem and after Nat’l Union II, the Insurers am ended their petition and
    reasserted the previously adjudicated claim s; therefore, Fisher and Zink both m oved for sum m ary judgm ent
    on all the claim s, again.
    19
    litigation, the law-of-the-case doctrine is intended to achieve uniformity of decision as well
    as judicial economy and efficiency. Briscoe v. Goodmark Corp., 
    102 S.W.3d 714
    , 716
    (Tex. 2003). The doctrine is based on public policy and is aimed at putting an end to
    litigation. 
    Id. If the
    first appeal involves a summary judgment, it may not be appropriate
    to apply the law-of-the-case doctrine if the summary judgment evidence offered in support
    of the second motion materially differs from that offered in support of the first motion. See
    Hudson v. Wakefield, 
    711 S.W.2d 628
    , 630 (Tex. 1986); see also Kropp v. Prather, 
    526 S.W.2d 283
    , 286 (Tex. Civ. App.–Tyler 1975, writ ref’d n.r.e.) (“Further, the doctrine does
    not necessarily apply where the issues presented at successive appeals are not identical
    and applies only if it appears on the second appeal that the facts are substantially the
    same as those involved on the first trial.”).
    We agree that we are not “bound” by our prior decisions, but rather, we retain
    discretion to revisit issues we previously decided that have not been finally determined by
    the Texas Supreme Court. Having decided to revisit the issues, however, we find our prior
    holdings to be sound, and we choose to rule the same way again with respect to all the
    claims. Here, although the Insurers have asserted new claims against Fisher and Zink, like
    those addressed in Nat’l Union II, the new claims are all derivative of Valero’s claims
    against Fisher and Zink. Nat’l Union II, 
    2005 WL 608229
    , at *4. Thus, the affirmative
    defenses of release and waiver apply identically to these new claims. Fisher and Zink
    have submitted the same evidence submitted in support of the motions for summary
    judgment that we affirmed in Nat’l Union II. 
    Id. at *5.
    Again, we find that Fisher and Zink
    have established their status as Kelogg’s subcontractors as a matter of law. Whether the
    trial court erred by reviewing claims already affirmed by this Court is irrelevant, and we
    20
    need not parse through the numerous amended petitions to decipher exactly what claims
    have previously been decided, because Fisher and Zink moved for summary judgment on
    all the claims and because we find that the trial court again correctly determined that the
    evidence conclusively established that Fisher and Zink were Kellogg’s subcontractors.
    B.     Valtek’s Evidence of Subcontractor Status
    In Nat’l Union II, Valtek did not argue that it was a subcontractor entitled to rely on
    the release and waiver provisions of the Valero/Kellogg contract. 
    Id. Thus, we
    did not
    affirm any part of the summary judgment in Valtek’s favor. 
    Id. On remand,
    however,
    Valtek submitted evidence of the same sort submitted by Fisher, which we found sufficient
    in Nat’l Union II, showing that: (1) Kellogg made an inquiry regarding Valtek’s bypass
    valves; (2) Valtek submitted a bid in response; and (3) Kellogg accepted the bid in the form
    of a purchase order. 
    Id. As with
    Fisher, we hold this evidence conclusively established
    that Valtek contracted with Kellogg to perform a portion of Kellogg’s required performance
    under the Valero/Kellogg contract. 
    Id. We choose
    to follow our holding in Nat’l Union II, but nevertheless, we will next
    address the arguments made by the Insurers as to why this type of evidence is insufficient
    as to all Contractors.
    C.     Distinguishing Between the Fisher Entities
    The Insurers argue that the three Fisher companies have no evidence that any of
    them contracted with Kellogg. The Insurers claim that the “subcontract” upon which the
    Fisher companies rely is really one purchase order contract between Kellogg and “Fisher
    Controls c/o Puffer-Sweiven, Inc.,” which does not refer specifically to any of the Fisher
    companies. Thus, they argue that the three Fisher companies cannot claim subcontractor
    21
    status. We disagree with the Insurers’ interpretation of the purchase order, particularly in
    light of the Insurers’ consistent allegations that all three Fisher companies had a role in the
    design of the control card and cabinet, which the Insurers alleged caused the citrate
    scrubber stack fire and which is the subject of the purchase order.
    In their tenth amended petition, on which the Contractors’ summary judgment was
    based, the Insurers referred to all three Fisher companies collectively as “Fisher” and
    alleged the following:
    9.     Also as part of Kellogg's provision of procurement services for Valero,
    on or about June 16,1981, Kellogg issued Purchase Order Number
    6216-010 to "Fisher Controls c/o Puffer-Sweiven, Inc." (the
    "Fisher/Kellogg Purchase Order") for the sale and delivery of a
    Distributed Control System which included the computer control card
    and housing cabinet at issue herein ("Control Card and Cabinet") for
    installation as part of the Refinery expansion. A true and correct copy
    of the Fisher Kellogg Purchase Order is attached hereto as Exhibit "C"
    and incorporated by reference.
    ....
    90.    The [Citrate Scrubber Stack] Fire was caused by defects in the Valves
    and/or Control Card and Cabinet and resulted in covered claims for
    property damages in the amount of $550,345.67.
    ....
    133.   . . . At all material times, Fisher was involved in the business of
    designing, manufacturing, distributing, selling or otherwise placing into
    the stream of commerce computer control cards and housing cabinets
    such as the ones used at the Refinery.
    Referring to all three companies collectively, the Insurers alleged that “Fisher” defectively
    designed, manufactured, installed, and inspected the control card and cabinet, among
    numerous other allegations seeking to hold all three Fisher companies liable for the citrate
    stack scrubber fire.
    The purchase order on which the Insurers rely refers to “Fisher Controls,” and it
    22
    serves as the basis for the Insurers’ claims against all three Fisher companies. For
    example, in the Insurers’ tenth amended petition, the Insurers specifically relied on the
    purchase order when asserting claims for breach of contract and for breach of contract-
    based warranties and guarantees. It is axiomatic that, if one of the Fisher companies did
    not perform work required by the Kellogg purchase order, it would not be liable to Valero
    for any portion of its damages, nor would it be liable to the Insurers for their wholly-
    derivative claims.
    Here, the Insurers have pleaded that a contract existed in order to establish liability
    over all three Fisher companies, without pleading in the alternative, but now are seeking
    to avoid the existence of that very contract to deprive the Fisher companies of a
    contractually-based defense. When a party makes a clear, deliberate, and unequivocal
    statement of fact in a live pleading submitted to the court, that fact is conclusively
    established as against that party, and the introduction of other pleadings or evidence is
    unnecessary. Horizon/CMS Healthcare Corp. v. Auld, 
    34 S.W.3d 887
    , 905 (Tex. 2000).
    Judicial admissions relieve an adversary from making proof of the fact, and more
    importantly, bar the party from disputing it. 
    Id. For example,
    in Auld, the plaintiff consistently pleaded that the defendant nursing
    home was a “health care provider” as that term was defined in former article 4590i. 
    Id. at 904.
    When the defendant sought to apply the damage caps in article 4590i, the plaintiff
    objected and claimed that the defendant failed to prove it was licensed or chartered by the
    State of Texas to provide health care and, therefore, was not entitled to rely on the caps.
    
    Id. The Texas
    Supreme Court held that the plaintiff’s allegations in her petition precluded
    her from disputing that the defendant was a health care provider entitled to rely on the
    23
    defenses provided in article 4590i. 
    Id. at 904-05.
    We likewise hold that the Insurers’ pleadings constitute judicial admissions that
    preclude them from disputing that any one of the Fisher companies was covered by the
    purchase order. See 
    id. Accordingly, we
    reject the Insurers’ argument that the Fisher
    companies were not subcontractors for this reason.
    D.     Sellers, Vendors, or Subcontractors?
    The Insurers claim that the Valero/Kellogg contract contemplated that Kellogg would
    deal with at least four different types of entities: subcontractors, vendors, suppliers, and
    third-party licensors. The Insurers contend that the contract treated each one of these
    categories differently for liability purposes. For example, vendors were not released from
    all liability but only for liability for consequential damages, and suppliers and third-party
    licensors were not subject to any liability at all. The Insurers argue that there are fact
    issues that preclude a finding that the Contractors are “subcontractors” because the
    alleged subcontracts repeatedly refer to the Contractors as “sellers” or “vendors,” which are
    distinct categories in the Valero/Kellogg contract. Specifically, the Insurers allege that the
    Contractors contracted to sell components—not to perform any of the services that Kellogg
    had contracted to perform. In other words, the Insurers argue that Kellogg was still
    performing its procurement role, and the Contractors were merely selling Kellogg
    component parts. We disagree.
    First, we disagree that the labels used by the purchase orders create fact issues on
    subcontractor status. As we held in Nat’l Union II, a “subcontractor” is “a party who takes
    and performs a portion of a contract from a principal contractor or who enters into a
    contract for the performance of an act with a person who has already contracted for its
    24
    performance.” Nat’l Union II, 
    2005 WL 608229
    , at *5. The Insurers point to no cases that
    hold that the label used in a purchase order determines the seller’s status under a
    completely separate contract, nor are we aware of any.
    Second, the Insurers’ argument is again contradicted by the purchase orders and
    their pleadings, in which they alleged that the Contractors did much more than merely “sell”
    the products that allegedly caused damages to the Valero plant.               See 
    id. The Valero/Kellogg
    contract required Kellogg to “design, engineer, provide procurement
    services together with certain construction coordination functions and furnish materials in
    connection with additions and modifications to its existing refining unit at Corpus Christi,
    Texas . . . .” The allegations in the Insurers’ tenth amended petition and the various
    purchase orders demonstrate that the Contractors assisted Kellogg in its “design” services
    by designing and manufacturing the items purchased to Kellogg’s and Valero’s
    specifications.
    1.     Zink
    In their tenth amended petition, the Insurers alleged that Zink manufactured a
    “vertical air preheater” that exploded on July 13, 1984. The Insurers, however, did not
    allege that Zink merely “sold” the heater to Kellogg. Rather, the Insurers alleged that Zink:
    (1) failed to comply with the specifications for the heater; (2) defectively designed the
    heater; (3) omitted an air-control mechanism; and (4) defectively manufactured the heater.
    All of these allegations demonstrate that Zink was not only “selling” the heater but was
    performing part of Kellogg’s obligation to “design” components of the plant. The Insurers
    cannot now claim that Zink was a mere seller. 
    Id. Furthermore, the
    Zink purchase order expressly states that Zink would receive
    25
    fifteen percent of its payment upon supplying Kellogg with “drawings” for its approval, which
    further demonstrates that Zink was not just “selling” the heater to Kellogg but was assisting
    Kellogg with design duties.
    2.     Fisher
    The Insurers alleged that on May 28, 1985, a citrate scrubber stack fire occurred
    that was caused by defects in the control card and cabinet Fisher manufactured. Again,
    the Insurers alleged that Fisher not only sold these items but also: (1) failed to properly
    design, construct, and inspect the items; (2) failed to manufacture the items according to
    Kellogg’s specifications; and (3) negligently advised Valero as to the use of the items.
    Again, these allegations claim that Fisher was assisting Kellogg with its design duties and
    attempt to hold Fisher liable for these services. The Insurers cannot now claim that Fisher
    was a mere seller of the control card and cabinet. 
    Id. Moreover, the
    Fisher purchase order expressly states that the pricing is based on
    hardware; “Dedicated Project Management and Engineering”; “Staging, Integration and
    Testing”; and freight costs. The terms and conditions further state that the items must be
    manufactured in “strict accordance with . . . Kellogg specifications and drawings except
    where noted otherwise in this Purchase Order.” Thus, Fisher was not merely “selling”
    items for Kellogg to incorporate into the Valero plant; it was also designing, testing, and
    staging these particular items on Kellogg’s behalf.
    3.     Valtek
    The Insurers alleged in their tenth amended petition that Valtek manufactured
    defective expander bypass valves that caused the citrate scrubber stack fire. The Insurers
    alleged that Valtek not only sold the valves but also:           (1) improperly designed,
    26
    manufactured, and inspected the valves; (2) failed to properly construct the valves; and (3)
    failed to comply with Kellogg’s specifications. Furthermore, the Valtek purchase order
    provides that Valtek was to supply the valves in accordance with Kellogg’s specifications
    and that Valtek was not entitled to final payment of its invoices until it completed the order
    and submitted data, documentation, and drawings as required by Kellogg. The purchase
    order also expressly refers to “engineering” and “manufacturing” to be performed by Valtek:
    “All questions of a technical nature that may arise during the Engineering and/or
    Fabrication or manufacturing stage of this order should be directed, in writing by either
    telex or letter, to the Inspection Department, Pullman Kellogg . . . .” Again, both the
    Insurers’ pleadings and the purchase orders demonstrate that Valtek was not a mere seller
    but also performed design functions on Kellogg’s behalf.
    In sum, the Insurers cannot claim that the Contractors defectively designed and
    manufactured these products and, at the same time, claim that the Contractors did not
    engage in any design or engineering services on behalf of Kellogg. See 
    Auld, 34 S.W.3d at 905
    . Moreover, the purchase orders establish that the Contractors did much more than
    merely sell a product. We overrule this argument.
    E.     Valero’s Lack of Consent
    Next, the Insurers argue that, although Kellogg was entitled to hire subcontractors,
    it could not do so without Valero’s consent. The Insurers point to the following provision
    in the Valero/Kellogg contract:
    15.2   Notwithstanding the foregoing, [Kellogg] may subcontract parts of its
    work to be performed under this Agreement upon obtaining the
    consent of [Valero] as provided in Exhibit “A”; providing, however, that
    in such event [Kellogg] shall not be relieved or released from any of
    27
    its obligations and responsibilities under this Agreement.7
    The Insurers argue that the Contractors did not present any evidence that Valero
    consented under this provision; therefore, they are not entitled to rely on the waiver and
    release provisions in the Valero/Kellogg contract. In support of their argument, the Insurers
    point to an affidavit by the plant’s project director, John Cotterell. Cotterell’s affidavit stated
    that “[a]t no time did I, or anyone else at or on behalf of Valero to my knowledge, ever
    receive a request from Kellogg, Zink, Fisher, Valtek or anyone else that Valero consent to
    Zink, Fisher, or Valtek performing any of the work or obligations that Kellogg had agreed
    to undertake for Valero under the Valero/Kellogg Contract.” The trial court sustained the
    Contractors’ objections to this affidavit, which the Insurers claim constituted error. We
    need not address the Contractors’ objections because we disagree that the affidavit raised
    a fact issue.
    It is undisputed that Kellogg began work on the expansion project before a formal
    contract had been negotiated or signed. It is also undisputed that the Valero/Kellogg
    contract had not yet been signed at the time of Kellogg’s purchase orders with the
    Contractors. Accordingly, at the time that Kellogg subcontracted with the Contractors,
    Valero had no right of prior approval. The contract, however, was made retroactive to the
    time that construction began. Thus, the Insurers argue that the Contractors had to obtain
    Valero’s consent. The resolution of these arguments depends on whether prior approval
    was a “condition precedent” to enforcement of the release and waiver provisions in the
    Valero/Kellogg contract. We hold it was not.
    7
    Exhibit A states that “Kellogg did not subcontract engineering work for this project.” W e hold this
    does not raise a fact issue, however, because as we noted above, the Insurers’ pleadings conclusively
    established that the Contractors engaged in design services on Kellogg’s behalf.
    28
    Conditions precedent in a contract are events that must occur or acts that must be
    performed before rights can accrue to enforce an obligation. See Centex Corp. v. Dalton,
    
    840 S.W.2d 952
    , 956 (Tex. 1992). Ordinarily, terms such as “if,” “provided that,” “on
    condition that,” or similar conditional language indicate the intent to create a condition
    precedent. Criswell v. European Crossroads Shopping Ctr., 
    792 S.W.2d 945
    , 948 (Tex.
    1990). Conditions precedent, which can cause forfeiture, are not favored under the law,
    and we will not construe a contract provision as a condition precedent unless we are
    compelled to do so by language that may be construed in no other way. See Reilly v.
    Rangers Mgmt., Inc., 
    727 S.W.2d 527
    , 530 (Tex. 1987). “If a contract contains a condition
    precedent, it must either have been met or excused before the other party's obligation can
    be enforced.” Cal-Tex Lumber Co. v. Owens Handle Co., 
    989 S.W.2d 802
    , 809 (Tex.
    App.–Tyler 1999, no pet.).
    There is no conditional language associated with this provision that would make
    Valero’s consent a prerequisite to its subcontractors’ reliance on the waiver and release
    provisions. In fact, the conditional language that is included relates to Kellogg’s continuing
    obligations under the contract despite a failure to obtain prior approval, which is evidence
    that Valero intended to look to Kellogg as its sole indemnitor for problems arising with a
    subcontractor’s work. We hold that the consent provision was a mere covenant and not
    a condition precedent.
    In any event, even if we were to construe the consent provision as a condition
    precedent, we would hold that the condition was excused or waived by Valero. The failure
    of a condition in a contract is excused when the party for whom the condition was intended
    to benefit, with knowledge of the failure of the condition, accepts performance of the
    29
    contract without insisting on satisfaction of the condition. See RESTATEMENT (SECOND ) OF
    CONTRACTS §§ 224, 225, 246 (1981); see also Abraxas Petroleum Corp. v. Hornburg, 
    20 S.W.3d 741
    , 751-52 (Tex. App.–El Paso 2000, no pet.); Purvis Oil Corp. v. Hillin, 
    890 S.W.2d 931
    , 937 (Tex. App.–El Paso 1994, no writ) (holding that parties to a joint operating
    agreement waived their right to insist that an operator own an interest in the properties at
    the time of the operator’s election, as required by a condition precedent in the joint
    operating agreement, where the parties accepted the operator’s services without
    objection).
    Valero allowed the Contractors’ products to be installed at the refinery, and now the
    Insurers rely on the purchase orders, which we have held demonstrate that the Contractors
    were acting as subcontractors, to argue that the Contractors owed duties to Valero.
    Specifically, the Insurers’ tenth amended petition alleged that after the sale, delivery, and
    installation of the Contractors’ products, Valero requested assistance from each of the
    Contractors to achieve proper operation of the products, and these requests occurred prior
    to the explosion and citrate scrubber stack fire. What all this shows is that Valero was
    aware that Kellogg had engaged the Contractors as subcontractors, yet it did not insist on
    the condition in the contract requiring Kellogg to obtain approval for these subcontractors.
    Accordingly, the condition was excused or waived by Valero’s acceptance of Kellogg’s
    performance, utilizing subcontractors, and the Contractors’ performance of the
    subcontracts, without requiring Kellogg to obtain Valero’s consent. See RESTATEMENT
    (SECOND ) OF CONTRACTS §§ 224, 225, 246; see also Abraxas Petroleum 
    Corp., 20 S.W.3d at 751-52
    ; Purvis Oil 
    Corp., 890 S.W.2d at 937
    . Thus, we reject the Insurers’ arguments
    that the failure by Kellogg to obtain Valero’s approval of the subcontracts precludes the
    30
    Contractors’ reliance on the release and waiver provisions.
    F.     Subcontractors’ Insurance Requirement
    Next, the Insurers argue that the Valero/Kellogg contract required Kellogg’s
    subcontractors to carry insurance, but the Contractors did not present evidence that they
    did so. Thus, the Insurers argue that the Contractors cannot invoke the waiver and release
    provisions in the Valero/Kellogg contract. In contrast, the Contractors argue that the
    subcontractor insurance provisions are irrelevant because there is nothing in the contract
    that requires the Contractors to make a claim under their own policies in order to be
    entitled to the benefit of the release and waiver provisions. We agree with the Contractors.
    The Valero/Kellogg contract requires in section 6.2(a), (b), and (c) that Kellogg
    obtain certain insurance policies for Valero’s benefit. Section 6.2, subparts (a) and (c),
    require Kellogg to obtain workers’ compensation insurance and automobile insurance for
    Kellogg’s employees, and those provisions are not relevant here. Section 6.2(b), however,
    requires Kellogg to obtain a comprehensive general liability insurance policy benefitting
    Valero and limits Kellogg’s liability to the amount of that policy, as follows:
    6.2    [Kellogg] shall provide the following insurance:
    ....
    (b).    Comprehensive General Liability Insurance (including
    Contractual Liability, Contractor’s Contingent Liability
    and Explosion, Collapse, and Underground damage)
    covering Bodily Injury and Property Damage with a
    Combined Single Limit of $2,000,000 per occurrence.
    It is understood and agreed that for the purposes of this
    agreement, [Kellogg] will be self-insured up to a
    Combined Single Limit of $2,000,000 per occurrence for
    bodily injury and damage to property (other than the
    work) arising out of [Kellogg’s] rendering of professional
    services under this agreement.
    31
    [Kellogg’s] liability with respect to [Valero’s] property so
    covered shall be limited to the amount of such
    insurance provided that in the event of a loss
    aggregating more than the amount of insurance in
    effect at the time of such loss [Kellogg’s] liability with
    respect to [Valero’s] property shall be limited to an
    amount equal to the ratio of [Valero’s] loss to the total
    amount of the loss multiplied by the total amount paid
    out by the insurance company with respect to such loss.
    [Valero] shall obtain for [Kellogg’s] benefit a waiver of
    subrogation rights consistent with that limitation under
    its insurance policies, if any, covering the property. In
    no event shall this provision or payments made in
    accordance herewith be viewed as limiting [Valero’s]
    rights to insurance coverage as an insured pursuant to
    paragraph 6.5(c) below.
    Then, in section 6.3, the contract provides that subcontractors will be required to carry
    insurance of the same “types,” but the amounts are to be set by Kellogg’s standard
    subcontract procedures. There is no suggestion that those insurance policies were to
    benefit Valero instead of Kellogg:
    6.3    [Kellogg’s] subcontractors will be required to carry insurance of the
    types described in subparagraphs (a), (b), and (c) of paragraph 6.2
    above, as appropriate, at limits considered adequate in accordance
    with [Kellogg’s] standard subcontract procedures.
    The release and waiver provisions, on which the Contractors rely, expressly state
    that Valero would release, defend, indemnify, and hold harmless Kellogg’s subcontractors
    to the extent that Kellogg, not the subcontractors, was compensated by insurance. Thus,
    we agree that the subcontractors insurance provision is irrelevant to a determination of the
    subcontractors’ ability to rely on the release and waiver provisions. Nat’l Union II, 
    2005 WL 608229
    , at *5.
    Having rejected all of the Insurers’ arguments, we find that the trial court did not err
    by holding that the Contractors qualified as “subcontractors” under the Valero/Kellogg
    contract.
    32
    IV. EXPRESS NEGLIGENCE
    The Insurers next argue that even if we conclude that the Contractors are
    “subcontractors” under the contract, the Valero/Kellogg contract does not validly waive or
    release Valero’s claims based on the subcontractors’ negligence because the contract
    does not satisfy the “express negligence” test. We disagree.
    “The express negligence requirement provides that when a party is seeking
    indemnity from the consequences of that party's own future negligence, that intent must
    be expressed in unambiguous terms within the four corners of the contract.” Oxy USA, Inc.
    v. Sw. Energy Prod. Co., 
    161 S.W.3d 277
    , 283 (Tex. App.–Corpus Christi 2005, pet.
    denied).   The express negligence doctrine applies both to indemnity and release
    agreements when “the effect of both is to relieve a party in advance of responsibility for its
    own negligence.” Dresser Indus., Inc. v. Page Petroleum, Inc., 
    853 S.W.2d 505
    , 509 (Tex.
    1993) (emphasis added). The reason for requiring a clear intent to relieve a party of future
    negligence is that these clauses seek to shift risk in an extraordinary way. Id.; see also
    Green Int’l, Inc. v. Solis, 
    951 S.W.2d 384
    , 387 (Tex. 1997). The express negligence
    doctrine, however, does not apply to indemnity or release agreements entered into after
    the transaction or occurrence giving rise to liability has already taken place. See Oxy USA,
    
    Inc., 161 S.W.3d at 283
    .
    The Insurers agree that the express negligence doctrine does not apply to contracts
    releasing parties from liability for negligence that has already occurred. However, they
    dispute that at the time the Valero/Kellogg contract was executed, the negligent acts had
    already occurred. The Insurers do not dispute that the purchase orders were filled and that
    the products were installed at the Valero facility prior to the execution of the Valero/Kellogg
    33
    contract in 1982. The Insurers, however, point out that the explosion allegedly caused by
    Zink’s defective preheater occurred in 1984, and the explosion allegedly caused by Fisher
    and Valtek’s products occurred in 1985. The Insurers claim that negligence does not
    become actionable until there is an injury; therefore, the express negligence rule must look
    to the dates giving rise to liability, including when an injury occurred. We disagree with this
    interpretation of the express negligence doctrine.
    In Lexington Insurance Co. v. W.M. Kellogg Co., the First Court of Appeals
    addressed a nearly identical situation. See generally 
    976 S.W.2d 807
    (Tex. App.–Houston
    [1st Dist.] 1998, no writ). There, Kellogg agreed to “design, engineer, and construct an
    ethylene manufacturing facility in Louisiana for Westlake Petrochemical Corporation.” 
    Id. at 808.
    A dispute arose about the work that Kellogg performed; therefore, after Kellogg
    completed the project, the parties executed the following release:
    For and in consideration of the cash, invoice cancellations, credit, benefits,
    mutual promises, and terms and conditions provided for in this Agreement,
    the receipt and adequacy of which are hereby expressly acknowledged by
    Westlake Polymers and Westlake . . . each individually and on behalf of its
    respective successors and assigns, do hereby and forever RELEASE,
    ACQUIT and DISCHARGE Kellogg . . . their officers, employees,
    shareholders, affiliates, subsidiaries, directors, attorneys, agents, legal
    representatives, successors and assigns of and from any and all claims,
    actions or causes of action, known or unknown, accrued or which may
    accrue in the future, for damages, injury, losses, costs, charges, expenses
    or liability of whatsoever kind or character, known or unknown, accrued or
    which may accrue in the future, arising out of or relating, directly or indirectly,
    to any of the Released Transactions.
    ....
    The term “Released Transactions[”]: means and includes any and all acts,
    omissions, promises, events, occurrences, warranties, representations,
    transactions, dealings, inducements or agreements of every kind or
    character relating directly or indirectly (i) to the negotiation, execution,
    performance, warranties, terms, conditions, rights and obligations, or any
    other aspect of the subject matter of the Project Agreement, (ii) to the Plant;
    34
    or (iii) to any engineering services, design work or other services of any kind
    or character performed directly or indirectly by Kellogg for Westlake
    Polymers and/or Westlake in connection with the Project Agreement for the
    Plant.
    
    Id. Two years
    later, there was an explosion at the plant, and Westlake sought insurance
    payments from its insurer, Lexington. 
    Id. Lexington, as
    Westlake’s subrogee, threatened
    to sue Kellogg and to claim that the release did not apply to claims of negligence or gross
    negligence, so Kellogg filed a declaratory judgment action. 
    Id. at 808-09.
    The trial court
    declared that the release was effective as to any claims arising from Kellogg’s services at
    the Westlake facility. 
    Id. at 809.
    On appeal, the First Court of Appeals held that the express negligence doctrine did
    not apply to the release because it was executed after the negligent acts—Kellogg’s
    provision of services at the Westlake facility—even though the explosion and resulting
    damages did not occur until after the release was signed:
    In the present case, the Agreement releasing Kellogg from liability, supported
    by consideration worth more than one million dollars, was drafted and signed
    after the acts which could give rise to liability were completed. The
    Agreement was signed after the construction of the plant had been
    completed, and it is uncontested a disagreement had arisen regarding
    Kellogg's performance. This case involves only claims for alleged negligence
    committed before the release was signed. Accordingly, the “fair notice
    doctrine” under Dresser does not apply.
    
    Id. We choose
    to follow Lexington because of the similarity of the facts. See 
    id. Valero and
    Kellogg began work on the plant before finalizing their contract, and Kellogg engaged
    subcontractors, who began designing and providing components before the Valero/Kellogg
    contract was signed.     Valero and Kellogg were aware of the risks that were being
    addressed in the contract. As we noted in Valero,
    35
    Valero and Kellogg are sophisticated entities, replete with learned counsel
    and familiarity with the oil refinery industry. They negotiated their working
    relationship over the course of almost three years, with Kellogg submitting
    several proposals for Valero’s review. . . . Valero, having bargaining power
    equal to Kellogg’s, agreed to the exculpatory clause in this contract. Valero
    possessed the resources necessary to ascertain and understand the rights
    it held on the date of the signing of the contract, and those it would hold in
    the future. Nevertheless, Valero, of its own accord, negotiated those rights
    away.
    
    Valero, 866 S.W.2d at 257-58
    . Accordingly, there was no “extraordinary shifting of the
    risks” in this case, and the express negligence rule does not apply. We overrule the
    Insurers’ argument.
    V. PURCHASE ORDER CLAIMS
    The Insurers argue that their claims under the purchase orders are independently
    viable and require the Contractors to compensate them for the losses at the Valero plant.
    The Contractors argue that the release and waiver provisions of the Valero/Kellogg
    contract bar these claims and that the parol evidence rule operates to exclude evidence
    of the indemnity language in the purchase orders.
    The Insurers further argue that their DTPA claims arising from the purchase orders
    could not be waived because the governing version of the statute at the time of the
    purchase orders deems them non-waivable. The Contractors argue that the controlling
    version of the DTPA is the version that was in effect when the Valero/Kellogg contract was
    signed, and under that version, the waiver was valid.
    A.     Parol Evidence Rule
    First, the Insurers argue that they have alleged claims based on the purchase
    orders, which they assert are “independently viable” and have not been ruled upon by this
    Court in our prior decisions. Specifically, the Insurers argue that the Contractors’ purchase
    36
    orders with Kellogg required the Contractors to compensate Valero "for loss of and/or
    damage to property caused in whole or in part by the negligence or willful acts of [the
    Contractors] in connection with the materials furnished hereunder, including without
    limitation, the installation, erection, repair, adjustment or operation thereof.” Thus, the
    Insurers argue that the waiver and release provisions in the later-signed Kellogg/Valero
    contract do not apply. We disagree.
    As we held in Nat’l Union II, the purchase orders were signed prior to the formation
    of the Valero/Kellogg contract. Nat’l Union II, 
    2005 WL 608229
    , at *5. We held that the
    Valero/Kellogg contract was a valid, integrated agreement with respect to the parties’
    liability, and that therefore, the parol evidence rule prohibited enforcement of an
    inconsistent prior or contemporaneous agreement. 
    Id. “As there
    was no subrogation by
    Kellogg to [the Insurers] of any claim it could pursue against its subcontractors, we find the
    provisions for liability discussed in the Zink and Fisher purchase orders were pre-empted
    by the express waiver of liability for Kellogg’s subcontractors in the later-signed Valero-
    Kellogg contract.” 
    Id. The Insurers
    argue that this holding was in error because the purchase orders and
    the Valero/Kellogg contract were contracts between different parties, and accordingly,
    neither the parol evidence rule nor the merger doctrine can allow one contract to trump,
    supersede, or “preempt” the other. In other words, there must be an identity of parties for
    these doctrines to apply. We disagree that the parol evidence rule does not apply under
    the circumstances of this case.
    Under the parol evidence rule, extrinsic evidence that contradicts, varies, or adds
    to the terms of an unambiguous written agreement is incompetent and inadmissible.
    37
    Zapata County Appraisal Dist. v. Coastal Oil & Gas Corp., 
    90 S.W.3d 847
    , 852 (Tex.
    App.–San Antonio 2002, pet. denied). It is true that the parol evidence rule does not apply
    to “strangers” to the contract; however, a third-party beneficiary of the contract may
    enforce the rule as against a party to the contract. Id.; see also Morrison Supply Co. v.
    M.W. Hamilton & Co., 
    411 S.W.2d 790
    , 793-94 (Tex. Civ. App.–Amarillo 1967, no writ)
    (“We also hold that the fact appellant was not a party to the contract did not preclude the
    parol evidence rule as being applicable to it. Its cause of action asserted against Hamilton
    and Hartford is based on the contract and bond. Since Morrison was in such privity with
    those instruments the parol evidence rule would be applicable to it.”).
    The Insurers’ claims are derivative of Valero’s claims. Valero was a party to the
    Valero/Kellogg contract, which expressly stated that it constituted the “entire understanding
    of the parties and supersedes any and all previous agreements and representations made
    prior to the date of execution of this Agreement.” Because Valero was bound to this
    provision, so are the Insurers.
    Valero does not dispute that Kellogg could have sought a release from claims
    already existing against its subcontractors, and that is what it did in section 6.8 of the
    Valero/Kellogg contract. The Contractors, therefore, are third-party beneficiaries of the
    release provision. The parol evidence rule prohibits Valero’s insurers from attempting to
    escape the plain language of the release provision by pointing to a separate, earlier,
    contradictory agreement between the Contractors and Kellogg. We adhere to our decision
    in Nat’l Union II, and we hold that the parol evidence rule prohibits the Insurers from relying
    on the purchase orders to escape the effect of the release and waiver provision in the
    Valero/Kellogg contract as to all claims.
    38
    B.     DTPA Claims
    The Insurers argue that they have pleaded new claims arising under the purchase
    orders, not addressed by Nat’l Union II, for DTPA violations. See TEX . BUS. & COMM . CODE
    ANN . §§ 17.46, 17.50. They assert that under the 1979 version of the DTPA, a consumer
    could not validly waive its claims because that version stated that “[a]ny waiver by a
    consumer of the provisions of this subchapter is contrary to public policy and is
    unenforceable and void.” See Act of May 21, 1973, 63rd Leg., R.S., ch. 143, § 1, 1973
    Tex. Gen. Laws 322 (the “1979 version”), amended by Act of June 8, 1981, 67th Leg.,
    R.S., ch. 307, § 1, 1981 Tex. Gen. Laws 863 ( the “1981 version”). In contrast, the
    Contractors argue that the 1981 version applies, which provided:
    Any waiver by a consumer of the provisions of this subchapter is contrary to
    public policy and is unenforceable and void; provided, however, that a
    consumer, other than the State of Texas or any political subdivision thereof,
    with assets of at least $25,000,000 or more at the time of such transactions,
    acts, or practices, may by written contract waive the provisions of this
    subchapter . . . .
    Act of June 8, 1981, 67th Leg., R.S., ch. 307, § 1, 1981 Tex. Gen. Laws 863 ( the “1981
    version”).8
    8
    This statute has been am ended m any tim es since 1981. The current version reads:
    (a)       Any waiver by a consum er of the provisions of this subchapter is contrary to public
    policy and is unenforceable and void; provided, however, that a waiver is valid and
    enforceable if:
    (1)     the waiver is in writing and is signed by the consum er;
    (2)     the consum er is not in a significantly disparate bargaining position; and
    (3)     the consum er is represented by legal counsel in seeking or acquiring the
    goods or services.
    (b)       A waiver under Subsection (a) is not effective if the consum er's legal counsel was
    directly or indirectly identified, suggested, or selected by a defendant or an agent of
    the defendant.
    (c)       A waiver under this section m ust be:
    (1)     conspicuous and in bold-face type of at least 10 points in size;
    39
    The Insurers claim that because the purchase orders were signed before the 1981
    version was enacted, the 1979 version applies, and Valero could not have waived its rights
    under the DTPA. The Contractors claim that the relevant contract is the Valero/Kellogg
    contract, which contains the release and waiver provisions, and therefore, the 1981 version
    applies. We agree with the Contractors.
    We addressed this issue in Valero, as it was asserted against Ingersoll-Rand,
    another of Kellogg’s subcontractors. There, we held:
    [Valero] contends that the 1977 version [of the DTPA] applies, the one
    in effect at the time the parties began negotiating this contract (1979) and at
    the time Kellogg began performing under it (1980). [Kellogg and Ingersoll-
    Rand] allege that the 1981 version, the one in effect at the time the
    [Valero/Kellogg] contract was signed (1982), is the applicable provision.
    The crux of this dispute remains whether the waiver and hold-
    harmless provisions in the contract are valid under the DTPA. Prior to
    August 31, 1981, the DTPA mandated that “any waiver by a consumer of the
    provisions of this subchapter is contrary to public policy and is void.” On
    August 31, 1981, section 17.42 was amended to allow that “a consumer . . .
    with assets of $25,000,000 or more at the time of such transactions, acts, or
    practices, may by written contract waive the provisions of this subchapter.”
    [Valero] argues that the 1981 amendment to the DTPA is to be
    applied prospectively only and that any cause of action arising in whole or in
    part prior to August 31, 1981, will not be affected by the provision allowing
    waivers by sophisticated corporations. Valero asserts that because it began

    sim ilar m eaning; and
    (3)       in substantially the following form : “I waive m y rights under the
    Deceptive Trade Practices-Consum er Protection Act, Section 17.41

    negotiations with Kellogg in July, 1979, and with Ingersoll-Rand in early
    1981, the pre-1981 version of the DTPA must apply.
    Valero maintains that Kellogg and Ingersoll-Rand made false
    representations during their respective negotiating periods . . . . These
    allegedly false representations having been made during the negotiating
    periods, Valero asserts that its DTPA cause of action arose at least in part
    at those times, and therefore the pre-1981 version of the Act must apply to
    Kellogg and Ingersoll-Rand.
    Kellogg counters that the version of the DTPA in effect at the time the
    relevant contract is signed provides the controlling law. It quotes, “a contract
    signed before the effective date of this Act is governed by the law in effect
    when the contract was executed.” Ingersoll-Rand contends that the provision
    in effect on the date the product at issue was delivered is the appropriate
    directive.
    We hold that the date that Valero signed the contract, which it now
    wishes to repudiate on the grounds of unconscionability and economic
    duress, is the relevant date of inquiry. Kellogg and Valero negotiated this
    contract for almost three years. . . .
    At the time of the signing of the contract, both parties were presumed
    to know the laws affecting their contract. They were presumed to know their
    rights, duties, and obligations under that contract.
    On May 28, 1982, the date Valero and Kellogg signed this agreement,
    Valero waived any claims that may have vested against Kellogg and against
    Ingersoll-Rand, its subcontractor, for deceptive trade practices. At that time,
    the August 31, 1981, DTPA amendment allowing large corporations to waive
    their rights under the Act had been in effect for almost a year. Valero, a
    sophisticated corporation, is charged with knowing the law affecting the
    contract on the date that it was signed. Notwithstanding when the causes of
    action at issue here accrued, whether in 1979, early 1981, or much later, in
    1982, the law allowed large corporations to waive their DTPA causes of
    action. This Valero did when it signed this contract.

    (citations omitted).
    Contrary to the Insurers’ arguments, we hold that the relevant contract is the
    Valero/Kellogg contract, signed in 1982, which contains the release and waiver provisions
    that the Insurers now seek to avoid. See 
    id. As we
    held with respect to Ingersoll-Rand,
    it does not matter that the claims the Insurers make now arise from purchase orders issued
    41
    prior to the effective date of the 1981 amendments. 
    Id. We hold
    that Valero, and
    derivatively the Insurers, validly waived all their DTPA claims in 1982.
    VI. LIMITATION OF THE RELEASE/WAIVER
    Finally, assuming the release and waiver provisions are valid and apply to the
    Contractors, the Insurers argue that it is a limited waiver and release that only released the
    Contractors from damages in excess of Kellogg’s insurance. The Insurers argue that the
    Contractors have not provided any evidence of the amount that Kellogg was compensated
    by insurance. The Insurers point to a statement by this Court in Nat’l Union I:
    To the extent that [Valero] may be interpreted to hold that all of
    Valero’s claims were waived by the contract, we hold that the waiver must be
    limited because of our reliance on sections 6.8 and 6.9 of the agreement.
    In other words, Valero agreed to absolve Kellogg and its subcontractors of
    liability for claims to the extent the contractor was not compensated by
    insurance and for those losses specified in section 6.9.
    Nat’l Union 
    I, 972 S.W.2d at 845
    . The Insurers argue that because there was no evidence
    of where the release begins to limit damages, the trial court erred in rendering a final
    summary judgment. We disagree.
    A fair reading of the release and waiver provision requires us to conclude that, in
    order to recover under the contract, the Insurers were required to look only to Kellogg for
    claims against both Kellogg and its subcontractors. Section 6.8 of the contract provided:
    [Valero] shall release, defend, indemnify and hold harmless [Kellogg], its
    subcontractors and affiliates and their employees performing services under
    this Agreement against all claims, liabilities, loss or expense, including legal
    fees and court costs in connection therewith, arising out of or in connection
    with this Agreement or the Work to be performed hereunder, including losses
    attributable to [Kellogg’s] negligence, to the extent [Kellogg] is not
    compensated by insurance carried under this ARTICLE. [Valero] shall obtain
    for the benefit of [Kellogg], its subcontractors and affiliates and their
    employees, waiver of subrogation rights under all its applicable insurance
    policies.
    42
    (Emphasis added). The contract does not say that Valero could recover from Kellogg the
    amount Kellogg was compensated by insurance and recover from Kellogg’s subcontractors
    the amount that Kellogg was compensated by insurance—such a construction would allow
    Valero to be compensated twice. As we noted in Nat’l Union II, the Valero/Kellogg contract
    did not provide for “subrogation by Kellogg to [the Insurers] of any claim it could pursue
    against its subcontractors,” and that is the reason that we affirmed final summary judgment
    on the claims then pending by the Insurers against the Contractors without regard to the
    amount that Kellogg was compensated by insurance. 
    2005 WL 608229
    , at *5.
    Accordingly, we hold that the lack of evidence of the amount that Kellogg was
    compensated by insurance does not preclude final summary judgment in the Contractors’
    favor. The Insurers’ recourse under the contract was limited to a suit against Kellogg for
    those amounts.
    VII. CONCLUSION
    Having overruled all subparts of the Insurers’ issue, we affirm the trial court’s final
    summary judgment.9

    The Insurers m ake additional argum ents regarding the applicability of other preclusion theories that
    would require us to adhere to our prior decisions. Having revisited all the issues raised by the Insurers against
    the sum m ary judgm ent, we conclude that these argum ents are not necessary to the disposition, and we do
    not address them . T EX . R. A PP . P. 47.4. Additionally, we need not address the Insurers’ argum ent that the
    trial court erred by denying their m otion for partial sum m ary judgm ent. The Insurers’ m otion did not seek a
    final judgm ent and, in any event, raised all the issues that we have addressed in this opinion that the Insurers
    also raised in defense to the Contractors’ m otion for sum m ary judgm ent. See Nat’l Union II, 2005 W L 608229,

    judgm ent at this tim e.”).
