Felix J. Campbell brought this action against Union Texas Petroleum Corporation ("UTP") and Sonat Offshore Drilling, Inc. ("Sonat")1 to recover for injuries allegedly sustained by Campbell as he attempted to transfer from the M/V TRUDY BRUCE, a vessel hired by UTP, to Sonat's drilling vessel, the OFFSHORE TAURUS. At the time he was injured, Campbell was employed by Frank's Casing Crew and Rental Tools, Inc. ("Frank's"), which was hired by UTP to perform casing services for an offshore drilling operation on the outer continental shelf.

Soon after Campbell brought this action against UTP and Sonat, UTP filed a Third Party Complaint against Frank's and its insurers, Certain Underwriters at Lloyd's and Companies ("Lloyd's"). UTP sought defense and indemnity for itself and Sonat pursuant to the terms of a contract between UTP and Frank's which governed the work Campbell was performing at the time he was injured. UTP then moved for summary judgment on this issue of Frank's duty to defend and indemnify; Frank's and Lloyd's (together "defendants") filed cross-motions for summary judgment on this same issue. Holding that Frank's must indemnify UTP and Sonat, the district court granted partial summary judgment in their favor. Defendants appeal, asserting that (1) Frank's never agreed to indemnify UTP or Sonat, (2) Louisiana law applies and invalidates any indemnity agreement between Frank's and UTP, (3) the Longshore and Harbor Workers Compensation Act (LHWCA), 33 U.S.C. § 901 et seq., prohibits any agreement by Frank's to indemnify Sonat, and, (4) if liable at all, Frank's is not liable to indemnify UTP and Sonat for more than $300,000. Finding that Frank's is obligated to indemnify UTP and Sonat pursuant to the terms of agreements between UTP and Frank's and UTP and Sonat, we affirm the district court's grant of partial summary judgment in favor of UTP and Sonat on this issue of indemnity.

This case arises out of UTP's efforts to drill a well in the outer continental shelf off the coast of Louisiana. To accomplish this, UTP hired a drilling vessel--the OFFSHORE TAURUS--from Sonat, and entered into a verbal agreement with Frank's to provide drive pipe, hammer work, and casing services2 on board the OFFSHORE TAURUS.

Campbell, a member of the casing crew provided by Frank's, was allegedly injured on December 10, 1988 while attempting to transfer from the M/V TRUDY BRUCE to the OFFSHORE TAURUS in adverse weather conditions on the high seas. Following Campbell's injury, Frank's continued to provide casing services for UTP and, on December 21, UTP issued a written purchase order to Frank's detailing the equipment and services provided. The back of this purchase order contains a provision for indemnification3 and another establishing insurance requirements.4 The purchase order also contains a provision which designates the laws of Texas as those governing the agreement.

Campbell brought this suit against UTP and Sonat to recover for the injuries he sustained on December 10, 1988. UTP, on its own behalf and on behalf of Sonat, then filed a Third Party Complaint against defendants for contractual defense and indemnity. All parties moved for summary judgment on this issue, UTP asserting that its purchase order constitutes a contract between the parties and that, in accordance with the indemnity provision on the back of the order, Frank's must indemnify. UTP also moved to strike the affidavit of Robert Gilbert, a Frank's employee, submitted by Frank's in opposition to UTP's Motion for Partial Summary Judgment on the grounds that this affidavit constitutes parol evidence intended to vary the terms of a written contract. The district court granted UTP's motions5 and denied those of defendants, holding that defendants must indemnify UTP and Sonat. Defendants appeal.

In considering the defendants' appeal from the district court's grant of partial summary judgment in favor of UTP and Sonat, we review the record de novo. See Topalian v. Ehrman, 954 F.2d 1125, 1131 (5th Cir.), cert. denied, --- U.S. ----, 113 S. Ct. 82, 121 L. Ed. 2d 46 (1992); International Shortstop, Inc. v. Rally's, 939 F.2d 1257, 1263 (5th Cir.1991), cert. denied, --- U.S. ----, 112 S. Ct. 936, 117 L. Ed. 2d 107 (1992). Our standard is well settled: Summary judgment is proper if the party moving for such a judgment establishes that there is an absence of genuine issues of material fact. See FED.R.CIV.P. 56(c); Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S. Ct. 2548, 2552, 91 L. Ed. 2d 265 (1986); Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250, 106 S. Ct. 2505, 2511, 91 L. Ed. 2d 202 (1986); Matsushita Elec. Ind. Col. v. Zenith Radio Corp., 475 U.S. 574, 585-88, 106 S. Ct. 1348, 1355-57, 89 L. Ed. 2d 538 (1986). Once a movant has made such a showing, the nonmovant must establish each of the challenged essential elements of its case for which it will bear the burden of proof at trial. See Catrett, 477 U.S. at 322, 106 S.Ct. at 2552; Topalian, 954 F.2d at 1131. Although the nonmovant may satisfy this burden by tendering depositions, affidavits, and other competent evidence,6 "[m]ere conclusory allegations are not competent summary judgment evidence, and they are therefore insufficient to defeat or support a motion for summary judgment." Topalian, 954 F.2d at 1131 (citations omitted). In short, "the adverse party's response ... must set forth specific facts showing that there is a genuine issue for trial." FED.R.CIV.P. 56(e). Where the nonmoving party fails to make such a showing and the moving party has met its summary judgment burden, the latter is entitled to summary judgment as a matter of law. FED.R.CIV.P. 56(c).

Defendants raise the following contentions on appeal: (a) the UTP-Frank's purchase order does not constitute a contract in effect at the time of Campbell's injury; (b) even if this agreement does constitute a contract in effect at the time of Campbell's injury, it is not maritime in nature and, therefore, it is governed by Louisiana law; (c) the indemnity provision of the UTP-Frank's agreement falls within the LHWCA's proscription against such indemnity provisions; (d) if liable at all, Frank's is not liable to indemnify UTP for more than $300,000; and (e) the district court erred in striking the Gilbert affidavit.

According to defendants, "the purchase order issued to Frank's by [UTP] thirteen days after the accident occurred cannot obligate Frank's to defend and indemnify [UTP] or Sonat." However, in response to UTP's and Sonat's assertion in their Third Party Complaint that, "[a]t all times pertinent, there was in full force and effect between [Frank's] and [UTP] a contract pursuant to which [Frank's] was required to defend, protect, indemnify and hold harmless [UTP] and [Sonat] from and against the claims filed by [the Campbells]," Frank's admitted "that there exists between [Frank's] and [UTP] a contract, which contract being a written instrument is the best evidence of its terms and conditions all of which are pled herein...."

We have held repeatedly that "factual assertions in pleadings are ... judicial admissions conclusively binding on the party that made them." Davis v. A.G. Edwards & Sons, Inc., 823 F.2d 105, 108 (5th Cir.1987) (emphasis in original), quoting White v. ARCO/Polymers, Inc., 720 F.2d 1391, 1396 (5th Cir.1983); see Ferguson v. Neighborhood Housing Services, Inc., 780 F.2d 549, 551 (6th Cir.1986) (facts admitted in pleadings are no longer at issue). Moreover, our reliance on Frank's original response to UTP's assertion that a contract was in force at the time of Campbell's accident is buttressed by evidence that (1) UTP and Frank's have conducted business on a regular, continuous basis for years, (2) it is common practice between UTP and Frank's for individual purchase orders to postdate the services rendered, (3) the basic indemnity language in these UTP-Frank's contracts has remained constant, and, (4) as for the specific contract at issue, UTP paid Frank's in accordance with the contract's terms and Frank's accepted that payment without objection. Where parties share a history of business dealings and standardized provisions have become part of those dealings, such familiar provisions within purchase orders issued after performance are binding where they are accepted without objection. See Grillet v. Sears, Roebuck & Co., 927 F.2d 217, 220 (5th Cir.1991) ("A party cannot be permitted to retain the benefits received under a contract and at the same time escape the obligation imposed by the contract."), superseded by statute, Oberg v. Allied Van Lines, Inc., 1992 WL 186098 (N.D.Ill. July 24, 1992) (No. 91 C 6576); see also M/V American Queen v. San Diego Marine Constr. Corp., 708 F.2d 1483, 1488-89 (9th Cir.1983) (in holding that standardized form of ship repair contract was enforceable even though executed after work was performed, recognizing that "it is a practice in the ship repair industry to do repair work before sending an invoice containing the contract for repairs"); Hudson Waterways Corp. v. Coastal Marine Serv., Inc., 436 F. Supp. 597, 604-05 (E.D.Tex.1977) (past business dealings provided sufficient notice to vessel owner that clause was implied in every repair contract). Accordingly, we conclude that the UTP-Frank's purchase order constitutes a contract between the parties in force at the time of Campbell's accident.

B. The Maritime Nature of the UTP-Frank's Agreement

Having determined that the UTP-Frank's purchase order constitutes a contract, we must consider defendants' challenge to the district court's conclusion that this contract is maritime in nature. According to defendants, "the Frank's [casing] crew was performing a task that was inherently non-maritime in nature, i.e. driving casing into the seabed of the Outer Continental Shelf. This fact alone is enough to invoke the application of Louisiana law pursuant to the mandates of the Outer Continental Shelf Lands Act."7 We disagree.

The Outer Continental Shelf Lands Act (OCSLA) provides, in pertinent part, that:

To the extent that they are applicable and not inconsistent with this subchapter or with other Federal laws and regulations of the Secretary now in effect or hereafter adopted, the civil and criminal laws of each adjacent State, now in effect or hereafter adopted, amended, or repealed are declared to be the law of the United States for that portion of the subsoil and seabed of the outer Continental Shelf, and artificial islands and fixed structures erected thereon, which would be within the area of the State if its boundaries were extended seaward to the outer margin of the outer Continental Shelf....

43 U.S.C. § 1333. To decide whether state law applies under the OCSLA, this court has set forth the following test:

[F]or adjacent state law to apply as surrogate federal law under OCSLA, three conditions are significant. (1) The controversy must arise on a situs covered by OCSLA (i.e. the subsoil, seabed, or artificial structures permanently or temporarily attached thereto). (2) Federal maritime law must not apply of its own force. (3) The state law must not be inconsistent with Federal law.

Smith v. Penrod Drilling Corp., 960 F.2d 456, 459 (5th Cir.1992), quoting Union Texas Petroleum Corp. v. PLT Eng'g, 895 F.2d 1043, 1047 (5th Cir.), cert. denied, --- U.S. ----, 111 S. Ct. 136, 112 L. Ed. 2d 103 (1990); see also Rodrigue v. Aetna Cas. & Surety Co., 395 U.S. 352, 355-66, 89 S. Ct. 1835, 1837-42, 23 L. Ed. 2d 360 (1969); Hollier v. Union Texas Petroleum Corp., 972 F.2d 662, 664 (5th Cir.1992).

The district court focused upon the second factor of this OCSLA test--the applicability of maritime law. Applying a two-part test introduced by this court in Davis & Sons, Inc., v. Gulf Oil Corp., 919 F.2d 313 (5th Cir.1990), to determine whether a contract is maritime, the district court found that Louisiana law under the OCSLA is inapplicable because the UTP-Frank's purchasing order constitutes a maritime contract.

In Davis, we addressed whether a blanket agreement and subsequent work orders linked to offshore oil and gas production constituted a maritime contract. In finding that they did, we held that:

Determination of the nature of a contract depends [A] in part on historical treatment in the jurisprudence and [B] in part on a fact-specific inquiry. We consider six factors in characterizing the contract: 1) what does the specific work order in effect at the time of injury provide? 2) what work did the crew assigned under the work order actually do? 3) was the crew assigned to work aboard a vessel in navigable waters; 4) to what extent did the work being done relate to the mission of that vessel? 5) what was the principal work of the injured worker? and 6) what work was the injured worker actually doing at the time of injury?

Id. at 316. In accordance with the first part of the Davis test, the district court looked to this court's established jurisprudence and found precedent that a contract to provide casing services is maritime. See Corbitt v. Diamond M. Drilling Co., 654 F.2d 329, 332 & n. 1 (5th Cir.1981) (holding that federal maritime law, rather than Louisiana law, controls construction of indemnity clause in purchase order for casing service), citing Transcontinental Gas Pipe Line Corp. v. Mobile Drilling Barge, 424 F.2d 684, 691 (5th Cir.) (contract for drilling work is maritime contract), cert. denied, 400 U.S. 832, 91 S. Ct. 65, 27 L. Ed. 2d 64 (1970); see also Davis, 919 F.2d at 315 & n. 5 (noting confusion as to whether contracts linked to offshore gas and oil production are governed by state or maritime law) (citations provided); Halliburton Co. v. Norton Drilling Co., 302 F.2d 431, 437 (5th Cir.1962) (maritime law controls drilling contract), cert. denied, 374 U.S. 829, 83 S. Ct. 1870, 10 L. Ed. 2d 1052 (1963). The district court then applied the fact-specific inquiry prescribed in Davis, and held that:

All six of the Davis factors support our finding that the contract was maritime. (1) The work contract between UTP and Frank's called for Frank's to deliver driver pipe and a hammer crew to the TAURUS, a vessel, to drive pipe into the seafloor. (2) The actual work, performed from December 10 to December 13, 1988 involved the driving or "hammering" of pipe into the seafloor, the welding of the next length of pipe to that already driven, and continued driving. (3) The work took place on a vessel, a special purpose watercraft, in navigable waters. (4) The labor the Frank's crew performed using the draw works and tackle of the vessel was "inextricably intertwined" with [the] mission of the TAURUS. Davis, 919 F.2d at 317. (5) The principal work of the injured party, Campbell, was welding which is also necessary for Frank's to complete its task. (6) Finally, Campbell was allegedly injured when attempting to board the TAURUS in rough seas from the M/V TRUDY BRUCE.

We agree with the district court. As we stated in Davis, "[t]he attempt to determine whether a contract, particularly one linked to offshore gas and oil production, is governed by state or maritime law has led to much confusion." 919 F.2d at 315. We also stated that this confusion, and what appear to be inconsistencies in our holdings, "can be traced to the highly fact-specific nature of the inquiry necessary to determine whether a contract is governed by maritime law." Id. Although the maritime/non-maritime line running through our jurisprudence concerning the nature of contracts linked to offshore gas and oil production is somewhat difficult to discern, we find that Corbitt and the authority undergirding this decision are enough to satisfy the threshold portion of the Davis test.8

We also agree with the district court's fact-specific inquiry under the second part of the Davis test. In challenging these Davis findings, defendants rely primarily upon our holdings in Domingue v. Ocean Drilling and Exploration Co., 923 F.2d 393 (5th Cir.1991), cert. denied, --- U.S. ----, 112 S. Ct. 874, 116 L. Ed. 2d 779 (1992), and Thurmond v. Delta Well Surveyors, 836 F.2d 952 (5th Cir.1988). In Domingue, the issue before this court was whether a contract to perform wireline services aboard a drilling vessel was governed by maritime or Louisiana law. This wireline work involved services to "partially drilled oil and gas wells and also [gathering] geophysical data relevant to production." 923 F.2d at 394 n. 3. Domingue was not employed by either party to the contract at issue, and his work--well testing--was unrelated to the wireline operations which were the subject of this contract. Id. at 395. In the absence of evidence that the vessel's equipment was in any way utilized to perform these wireline services or that these services were significantly related to the vessel's mission, we concluded that the vessel in Domingue merely served "as a work platform" upon which the wireline services were performed and that such services were only incidentally related to the vessel's mission. 923 F.2d at 397. Similarly, Thurmond involved wireline services and maintenance to a structure characterized as "a fixed platform" or "small ... island" located within Louisiana's territorial waters, and the plaintiff's injury resulted from a defect in this platform. 836 F.2d at 955. In short, Domingue is controlled by the nonmaritime nature of Domingue's work and the fact that he performed a service only remotely related to the mission of the vessel, and Thurmond is controlled by jurisprudence establishing that operations performed on fixed platforms in state waters are non-maritime in nature. See Herb's Welding, 470 U.S. at 422, 425, 105 S. Ct. at 1426, 1428; Rodrigue v. Aetna Cas. & Sur. Co., 395 U.S. 352, 361-66, 89 S. Ct. 1835, 1840-42, 23 L. Ed. 2d 360 (1969).

As stated above, Campbell was injured on the high seas when transferring from one vessel, the TRUDY BRUCE, to another,9 the OFFSHORE TAURUS--a jackup drilling rig, which is one of the special-purpose watercraft that this court has explicitly characterized as vessels.10 See Domingue, 923 F.2d at 394 n. 1; Lewis v. Glendel Drilling, 898 F.2d 1083, 1088 (5th Cir.1990) (commenting that en banc review would be necessary to treat special purpose vessels as artificial islands); Theriot v. Bay Drilling Corp., 783 F.2d 527, 538-39 (5th Cir.1986). Although it is conceivable that a vessel such as the OFFSHORE TAURUS may be used as a mere work platform to execute a particular service contract, see Domingue, 923 F.2d at 397, this is not the case before us.11 Campbell was a member of a casing crew which, using the OFFSHORE TAURUS's equipment--for example, the vessel's derrick and draw works--to accomplish their task, was contracted to travel upon the OFFSHORE TAURUS and perform their work from the vessel, the mission of which was to drill oil and gas wells over navigable waters. In other words, the work performed by Campbell and the rest of Frank's crew was "inextricably intertwined with maritime activities since it required the use of a vessel and its crew."12 Davis, 919 F.2d at 317; see also McDermott Intern., Inc. v. Wilander, 498 U.S. 337, ---- - ----, 111 S. Ct. 807, 817-18, 112 L. Ed. 2d 866 (1991) (the work of a paint foreman contributes to the function of a paint boat and the accomplishment of its mission); Offshore Co., 266 F.2d at 779 (the work of a roustabout contributes to the mission of a submersible drilling barge).

In sum, Campbell was injured while working as part of a crew contracted to travel upon and enable a special-purpose vessel to perform the function for which that vessel was designed. The vessel nature of THE OFFSHORE TAURUS is therefore controlling in this case, and we find that the underlying contract between Frank's and UTP, a contract for services to enable THE OFFSHORE TAURUS to complete its mission, is maritime in nature.

Section 905(b) of the LHWCA protects the employers of those engaged in shore-based maritime employment from indemnification claims brought by vessels in instances where the negligence of vessels causes injuries to these maritime employees. Specifically, section 905(b) provides, in pertinent part, that,

[i]n the event of injury to a person covered under this chapter caused by the negligence of a vessel, then such person, or anyone otherwise entitled to recover damages by reason thereof, may bring an action against such vessel as a third party in accordance with provisions of section 933 of this title, and the employer shall not be liable to the vessel for such damages directly or indirectly and any agreements or warranties to the contrary shall be void.

33 U.S.C. § 905(b). However, with the enactment of section 905(c) in the 1984 amendment to the LHWCA, Congress created the following exception to 905(b)'s proscription of indemnity for instances in which employers and vessels enter into reciprocal agreements to defend and indemnify each other:

Nothing contained in subsection (b) of this Section shall preclude the enforcement according to its terms of any reciprocal indemnity provision whereby the employer of a person entitled to receive benefits under this chapter by virtue of Section 1333 of Title 43 and the vessel agreed to defend and indemnify the other for cost of defense and loss or liability for damages arising out of or resulting from death or bodily injury to their employees.

33 U.S.C. § 905(c). Frank's asserts that Sonat's claim for indemnity is independent of UTP's claim and that, because Sonat was not a signatory to the UTP-Frank's purchase order and owes no indemnity under that contract, Sonat has failed to satisfy 905(c)'s reciprocity requirement.13 We disagree.

The legislative history behind section 905(c) is sparse,14 and the only guiding authority presented by the parties is found in a footnote to this court's opinion in Fontenot v. Mesa Petroleum Co., 791 F.2d 1207 (5th Cir.1986). In Fontenot, where the owner of a drilling vessel and a petroleum company entered into a reciprocal agreement to indemnify each other "for injuries sustained by [their own] personnel, contractors, and property[,]" we stated that "[t]his type of mutual provision is precisely the type envisioned in and sanctioned by the 1984 amendments to the Longshoremen's and Harbor Workers' Compensation Act." Id. at 1213 n. 3 (citations omitted).15

The Supreme Court has stated that, when interpreting statutory provisions, "[o]ur task is to give effect to the will of Congress, and where its will has been expressed in reasonably plain terms, 'that language must ordinarily be regarded as conclusive.' " Griffin v. Oceanic Contractors, Inc., 458 U.S. 564, 570, 102 S. Ct. 3245, 3250, 73 L. Ed. 2d 973 (1982) (citations omitted); see also United States v. Levy, 969 F.2d 136, 142 (5th Cir.1992) (refusing to restrict plain language of the aiding and abetting statute). The plain language of section 905(c) requires reciprocity between vessels and employers wishing to enter into agreements to indemnify, not privity. Although Sonat may not have agreed to directly indemnify Frank's pursuant to the UTP-Frank's agreement, it did agree to do so pursuant to the drilling contract entered into by Sonat and UTP. Specifically, just as Frank's expressly agreed to indemnify Sonat and UTP's other contractors for claims brought by Frank's employees, Sonat agreed to hold Frank's and UTP's other contractors

harmless from and against all claims, demands[,] and causes of action of every kind and character, without limit and without regard to the cause(s) thereof or the negligence of any party or parties (including [UTP] and its other contractors) arising in connection herewith, for injury to or illness or death of [Sonat's] employees and for all damage to, loss or destruction of property of [Sonat's] employees.

In sum, Sonat and Frank's were brought together by UTP solely for the purpose of carrying out UTP's oil-drilling operation.16 In contracting with UTP, Frank's and Sonat explicitly agreed to indemnify each other, and these agreements are unambiguous and completely reciprocal. See supra note 3 (quoting the indemnification provision of the UTP-Franks' agreement); see also Babcock v. Continental Oil Co., 792 F.2d 1346, 1351-53 (5th Cir.1986) (where contractor agreed to indemnify platform owner and its contractors for claims resulting from negligence of platform owner and/or its contractors, holding that negligent contractor who was not a signatory to the indemnity agreement was entitled to indemnity); Mills v. Zapata Drilling Co., 722 F.2d 1170, 1174 (5th Cir.1983) (where language similar to that contained in the instant contract was at issue, finding it "preposterous for [the contractor] to argue that the indemnity agreement is ambiguous."), overruled on other grounds, Kelly v. Lee's Old Fashioned Hamburgers, Inc., 908 F.2d 1218 (5th Cir.1990) (en banc). Accordingly, we conclude that the reciprocity requirement of section 905(c) has been satisfied and that the absolute privity requirement between vessels and employers which Frank's reads into section 905(c) is beyond the statute's plain language.17 Cf. Federal Marine Terminals v. Burnside Shipping Co., 394 U.S. 404, 418-21, 89 S. Ct. 1144, 1152-54, 22 L. Ed. 2d 371 (1969) (suggesting that reciprocity can exist without privity, so as to require indemnity).

D. Validity of the Amount of the Indemnity Provision

We have held that the UTP-Frank's agreement is maritime in nature, and, "under admiralty law, where the parties have included a choice of law clause, the state's law will govern unless the state has no substantial relationship to the parties or the transaction or the state's law conflicts with the fundamental purposes of maritime law." Stoot v. Fluor Drilling Serv., Inc., 851 F.2d 1514, 1517 (5th Cir.1988) (emphasis added). The UTP-Frank's agreement contains a choice of law provision stating that "[t]his order shall be governed by the laws of the State of Texas[,]" and a related insurance provision requiring the parties to carry $1,000,000 in general liability coverage. See supra note 4 (quoting this insurance provision). Because UTP is headquartered in Texas, we conclude that Texas has a substantial relationship to the contracting parties. We also conclude that the UTP-Frank's indemnity agreement is enforceable under Texas law,18 and that application of Texas law in the instant case would not conflict with "the fundamental purposes of maritime law." See Fontenot, 791 F.2d at 1214 (stating that, under maritime law, "[a] contract of indemnity should be construed to cover all losses, damages, or liabilities which reasonably appear to have been within the contemplation of the parties" ), quoting Corbitt, 654 F.2d at 333.

The parties disagree as to which version of Texas law governs the UTP-Frank's indemnity agreement. Specifically, at the time Campbell was injured (December 10, 1988), Texas law provided that Frank's was required to secure underlying liability insurance coverage for the indemnity obligation it assumed under the UTP-Frank's contract, but also that the amount of insurance required in a contract could not exceed $300,000. See TEX.CIV.PRAC. & REM.CODE ANN. § 127.005 (Vernon 1986 & Supp.1992). Effective September 1989, this latter provision was modified to permit mutual insurance requirements of any amount. A comment to this amendment provides that "[t]his act applies to an indemnity obligation without regard to whether the obligation was entered into before, on, or after the effective date of this Act." Id. comment (Supp.1992).

Relying upon an unpublished district court opinion in Meche v. Kerr McGee, CA 86-3678 (W.D.La.1990), Frank's asserts that the modified act is retroactive for agreements entered into before its effective date, but not to accidents occurring before this date.19 We do not reach the merits of Frank's assertion for Frank's procured $10,000,000 in excess insurance and, even under the unamended version of section 127.005 which Frank's relies upon, UTP is entitled to collect indemnity up to the amount of insurance Frank's actually obtained. See Lirette v. Union Texas Petroleum Corp., 467 So. 2d 29, 34 (La.App. 4th Cir.1985) (holding that Texas' $300,000 limit on insurance pursuant to indemnity contract did not place an absolute $300,000 limit on each claim where the contractor voluntarily provided more insurance); see also Maxus Exploration Co. v. Moran Bros., 773 S.W.2d 358, 361 (Tex.App.--Dallas 1989) (where indemnification was limited by statute, requiring party to indemnify up to the amount of insurance actually obtained on grounds that "[t]he purpose of the section 4(c) limit is to protect a weaker party from being coerced by a stronger party into providing high indemnity protection"), aff'd on other grounds, 817 S.W.2d 50 (Tex.1991). Accordingly, we affirm the district court's determination that Frank's must indemnify for the full amount of the UTP-Frank's agreement.

Defendants also reassert20 their challenge to the district court's decision to strike the Gilbert affidavit, which defendants submitted in opposition to UTP's Motion for Summary Judgment. According to defendants,

Judge Scott struck Gilbert's affidavit concluding that it was extrinsic evidence intended to vary the terms of the [UTP-Frank's] purchase order number 86-0806.... [T]his affidavit was not submitted to vary the terms of purchase order number 86-0806, but was rather submitted to show that purchase order 86-0806 (which was post-dated and thus ambiguous), did not apply to the present situation.

Gilbert's affidavit testimony indicates that Frank's had no intent to indemnify UTP and Sonat. This is parol evidence and, because the UTP-Frank's purchase order is unambiguous, it is not admissible.21 See Jack H. Brown & Co. v. Toys R Us, Inc., 906 F.2d 169, 173-74 (5th Cir.1990) (parol evidence is inadmissible "to vary or contradict" the terms of an unambiguously written contract.").22

As for defendants' assertion that their purpose for introducing this affidavit was to show that the UTP-Frank's purchase order does not apply to Campbell's injury, we have already addressed this issue. See supra Part III.A. In sum, we have found that (1) Frank's admission as to the binding effect of the UTP-Frank's purchase order and (2) the fact that it is common practice between UTP and Frank's for individual purchase orders--purchase orders which have consistently contained the basic indemnity language at issue--to postdate the services rendered remove any ambiguity arising from the fact that the purchase order was postdated. Gilbert's affidavit does not shake this finding, and, therefore, it does not create a genuine issue of material fact pursuant to Rule 56 of the Federal Rules of Civil Procedure.

For the foregoing reasons, we AFFIRM the district court's grant of partial summary judgment in favor of UTP and Sonat and its denial of summary judgment in favor of Frank's and Lloyd's.
