GEE, Circuit Judge:
On this appeal we must decide which creditor of a mercantile chain enjoys priority to repayment from the proceeds of the sale of assets of three supermarkets, aggregating $86,672. One of these is the Small Business Administration (hereinafter SBA), an avatar of the United States, serving as the guarantor of a private loan to the debt- or. SBA claims the special priority enjoyed by the sovereign in collecting taxes and the debts owed it by insolvents. We conclude that the SBA lacks priority under either state or federal law.
The other parties are the debtor, 0. K. Supermarkets, Inc. (hereinafter O.K.), and a private lender, Kimbell Foods, Inc. (hereinafter Kimbell). O.K. is a Dallas supermarket chain. The bulk sale of fixtures, equipment and inventory of three of its stores forms the fund to which the parties seek priority. O.K. owed Kimbell because of weekly inventory sales to O.K. on open account. Much of the factual background from which the claims of the parties emerge is undisputed.
O.K. executed three security agreements and financing statements to Kimbell. The first was in August 1966, securing a $20,000 promissory note from Kimbell. The collateral listed included supermarket equipment and fixtures and “[a]ll goods, wares and merchandise and any and all additions or accessions thereto.” In April and November of 1968, O.K. executed the remaining security agreements and financing statements to secure a $27,000 promissory note from Kimbell. The collateral for these two agreements was again specifically identified equipment normally used in a supermarket and “[a]ll goods, wares, merchandise and stock in trade and accessions.” Each of the security agreements was duly filed, and no termination statement was filed on any of the agreements. It is of particular importance to this case that each of the security agreements included the provision that “said security interest also being given to secure the payment of all other indebtedness at any time hereafter owing by Debtor to Secured Party as well as the discharge of all obligations imposed upon Debtor hereunder.”
On February 2, 1969, O.K. borrowed $300,000 from Republic National Bank of Dallas (hereinafter Republic). The SBA guaranteed 90% of this loan. On February 18, 1969, Republic filed with the Secretary of State of the State of Texas a security agreement and financing statement exe[494]*494cuted by O.K. to Republic granting it a security interest in all of the debtor’s machinery, fixtures, equipment, inventory and all additions and accessions thereto.1 When 0. K. defaulted on this note the SBA paid Republic 90% of the outstanding indebtedness, some $252,313.93, and on January 21, 1971, Republic assigned the SBA 90% of the note and financing statement.
Events subsequent to the 1969 loan of $300,000 form perhaps the most important part of this tableau. When Republic made its loan, O.K. owed Kimbell $24,893.10 on the 1968 note for $27,000. O.K. paid off this note from the Republic loan proceeds. Thus, both the 1966 note2 and the 1968 note between O.K. and Kimbell had been satisfied. O.K. still, however, owed Kimbell $18,390.93 on open account for inventory purchases. After February 12, 1969, O.K. paid Kimbell $18,390.93 against that debt— payments Kimbell credited to O.K.’s oldest outstanding balances. O.K. kept on making inventory purchases from Kimbell on open account until January 15, 1971. By then the balance of O.K.’s account with Kimbell was $18,258.57. On January 15, 1971, Kim-bell filed suit in Texas courts to recover that amount and, on January 31, 1972, obtained a judgment for $24,445.37—$18,-258.57 principal, $1,186.80 interest and $5,000 attorneys’ fees.
Both the SBA and Kimbell claimed priority in the $86,672 proceeds of the sale of three O.K. Supermarkets. After hearing the evidence and considering the stipulations of the parties the court ruled that the SBA had priority superior to all inchoate liens by virtue of its special status as a federal lien creditor. The district court ruled Kimbell’s lien inchoate because Kim-bell had not reduced its lien to judgment before the SBA guaranteed Republic’s note or before the SBA made good on its guarantee. The court went on to rule that Kimbell did not have a good security interest in the goods sold at bulk sale, a fact that certainly rendered its lien inchoate. Kim-bell appeals.
Kimbell’s Lien
We must first determine whether the district court properly held that Kim-bell’s security agreements securing the 1966 and 1968 notes did not cover the advances Kimbell made to O.K. on open account.3 The security agreements provide that the security interest also secures the payment of future indebtedness between the parties. Texas law countenances such so-called “dragnet clauses.” See Tex.Bus. & Com. Code § 9.204(e) (Tex.U.C.C.).4 Acknowledging this apparent approval of future advance clauses, the district court ruled that [495]*495the future advance clause did not operate in this case. It relied on pre-Code Texas cases and U.C.C. cases from other jurisdictions to restrict the application of the future advance clause to future debts clearly contemplated by the parties. So reasoning, it ruled that in this case the parties meant the security agreements to cover only the notes for which they were executed, not later purchases on open account. We view the transactions differently.5
Although the district court correctly stated the law of Texas, it arrived at the wrong conclusion in light of Texas’ application of its law. Texas courts do not recognize the application of a future advance clause unless the future advance to be secured was “reasonably within the contemplation of the parties to the mortgage at the time it was made.” Wood v. Parker Square State Bank, 400 S.W.2d 898, 901 (Tex.1966). See also Moss v. Hipp, 387 S.W.2d 656 (Tex.1965); Wallenstein & St. Claire, Annual Survey of Texas Law— Property, 30 Southwestern L.J. 28, 53 n. 214 (1976).6 Consistent with this view, in Texas a future advance clause in a mortgage does not secure a subsequent debt from the debt- or to a third party acquired from the third party by the mortgagee. See Wood, supra. In circumstances similar to those at bar, however, Texas courts have hinted that future advance clauses will be effective. In Wood, for example, the Texas Supreme Court remarked that:
The more reasonable construction of this general language [a future advance clause] is that it referred to obligations directly arising between Lincoln Enterprises [the original debtor] and respondent bank [the original lender], i. e., where Lincoln became obligated to the bank as the maker of an obligation, or became liable in a secondary capacity in favor of the bank.
Supra at 902. See also Estes v. Republic National Bank, 462 S.W.2d 273 (Tex.1970); Wallenstein & St. Claire, supra at 53 n.214. In light of this evidence we conclude that in Texas a further extension of credit to the debtor by the lender is deemed future indebtedness reasonably contemplated by the parties when they execute a future advance clause.
The district court concluded that the parties did not intend the future advance clause to cover purchases on open account because the security agreements were intended to cover only the amounts loaned under a promissory note. In reaching this conclusion, however, the district court ignored two important factors: the parol evidence rule and Texas’ treatment of future advance clauses in analogous situations. The district court admitted testimony by Harold Kindle, the president of O.K., about the subjective intention of the parties when they executed the 1966 and 1968 notes, security agreements and financing statements. Although his testimony was equivocal,7 the district court understood him [496]*496to say that the parties intended each transaction to be separate and distinct. Admission of such testimony was error. The language of the contract, unless ambiguous, represents the intention of the parties. The intent deduced from this objective matter, not the parties’ subjective understandings, is controlling. See Western Oil Fields, Inc. v. Pennzoil United, Inc., 421 F.2d 387, 390 (5th Cir. 1970); City of Pinehurst v. Spooner Addition Water Co., 432 S.W.2d 515, 518 (Tex.1968); Wall v. Lower Colorado River Authority, 536 S.W.2d 688, 691 (Tex.Civ. App.—Austin 1976, writ ref’d n. r. e.). See also First National Bank v. Rozelle, 493 F.2d 1196, 1201 (10th Cir. 1974). Testimony as to O.K.’s subjective intent in receiving the future advance clause was a classic violation of the parol evidence rule and clearly inadmissible.
The district court compounded this error by failing to consider the truest test of the parties’ intention, the words of the contract clearly providing that the security agreement should cover future indebtedness. In Estes v. Republic National Bank, 462 S.W.2d 273 (Tex.1970), the Texas Supreme Court upheld the applicability of a future advance clause despite the debtor’s claim of an oral agreement that the deed of trust containing the future advance clause was intended as a separate transaction not to extend to other indebtedness between the parties. In the absence of some evidence that the “dragnet clause” was placed in the contract by mutual mistake, the court found that the clause clearly and unequivocally stated the intention of the parties for the land to secure the debtor’s other loans from the bank. See also Wood, supra. In light of the Estes and Wood cases, the district court improperly discarded these future advance clauses.
The district court also relied on the circumstances surrounding the 1966 and 1968 loans in finding that the parties treated each loan as a separate and distinct agreement for a specific, nonrecurring purpose and to determine that the later inventory purchases were unrelated. Examining the documents and the circumstances surrounding their execution, we find nothing that negates the parties’ statement that the security agreements cover the inventory purchases on account.
The 1966 promissory note was entered into to free O.K.’s current cash flow to purchase fixtures for a new store and to allow O.K. to buy opening inventory from Kimbell on credit. At least in part, then, the 1966 security agreement contemplated the purchase of inventory on credit. The security agreement states that it is given “to secure an advance of goods, wares and merchandise and does not include a preexisting debt.” Under these circumstances we cannot say that later inventory purchases on credit by O.K. were “unrelated” to the 1966 security agreement or involved future advances “not of the same class” só as to negate the applicability of the future advance clause, as the district court held. See 401 F.Supp. at 325-26.
Again in 1968, O.K.’s promissory note allowed it to delay payment on its open-account purchases so as to free current cash flow to pay off a debt owed Associated Grocers, Inc. The 1968 security agreement and financing statements were again related to KimbelPs inventory advances on open account to O.K.8 Although the notes, security agreements and financing statements were executed in response to special factual circumstances, those circumstances are not necessarily inconsistent with giving the future advance clauses in those agreements their plain meaning, see First Na[497]*497tional Bank v. Rozelle, supra at 1201, holding that Kimbell’s 1966 and 1968 security agreements and financing statements covered its later advances of inventory to O.K. on open account.
Priority Under State Law
We now consider whether Kimbell had priority under state law. If it did not, we need not consider the more pressing questions of the applicability of federal law and the relative priority of federal liens. See United States v. P. S. Hotel Corp., 527 F.2d 500, 501 (8th Cir. 1975). As the assignee of Republic’s 1969 note and security agreement, the SBA may assert whatever priority that note might command under state law. The district court did not directly address the question of Republic’s priority qua noteholder because of its view that Kimbell’s security agreements with O.K. did not secure future advances. We find that they did, but even so the security agreement of February 18, 1969, between Republic and O.K. might be thought prior for two reasons. First, Republic may have established a security interest superior to that of Kimbell. Second, the 1969 note might be thought prior to secured future advances made after February 18, 1969. After reviewing the Texas law, we conclude that neither of these theories accords the SBA, standing in the shoes of Republic, priority in the proceeds from the bulk sale.
Republic could obtain a superior security interest in the collateral, notwithstanding Kimbell’s previously filed security agreement, if Republic attained a purchase money security interest in the collateral. The Uniform Commercial Code, adopted in Texas, provides that a purchase-money security interest in collateral except inventory has priority over a conflicting security interest in the same collateral if the purchase money security interest is properly perfected. Tex.Bus. & Com.Code § 9.314(d) (1968) (Tex.U.C.C.). Unfortunately for Republic and the SBA, the record reflects no purchase of goods by O.K. with the proceeds of the $300,000 note that could give rise to a purchase-money security interest in any items sold at the bulk sale—except inventory.
O.K. used some of the funds from the $300,000 note to purchase inventory. Texas law affords Republic a purchase-money security interest in that inventory and grants Republic priority: if the security interest was perfected at the time the debtor received possession; if the holder of the purchase-money security interest notified the holders of prior security interests before the debtor received possession of the collateral; and if that notice stated that the person giving notice had or expected to acquire a purchase-money security interest in the specifically described goods. Tex. Bus. & Com.Code § 9.312(c) (1968) (Tex.U.C. C.). Republic did not give the required notice to Kimbell so as to establish priority in the inventory. See Borg Warner Acceptance Corp. v. Wolfe City National Bank, 544 S.W.2d 947, 951 (Tex.Civ.App.—Dallas 1976, no writ). Kimbell was vaguely aware that Republic was planning to loan O.K. funds and would expect to acquire a lien, but Republic never gave Kimbell the notification requisite for priority under the Code. Republic never notified Kimbell that it expected to acquire a lien on the inventory, nor did it describe the inventory by item or type. Republic thus forfeited whatever priority it could have attained. Republic had priority, therefore, only if its lien was prior in time to Kimbell’s.
Here we again inquire into the nature of the future advance clause and the security interest it creates, a particularly important endeavor when, as here, the inquiry determines the status of the lien of an intervening secured creditor. The Texas U.C.C. provides in § 9.312(e)(1) that the first filed of conflicting security interests perfected by filing prevails. Tex.Bus. & Com.Code § 9.312(e)(1) (1968) (Tex.U.C.C.). In this case both Kimbell’s and Republic’s security interests were perfected by filing; Kimbell would normally have priority unless the future advance did not qualify because of the creation of an intervening security interest. The circumstance of a future advance after an intervening filed se[498]*498curity interest does not alter the scheme, however. When both interests are filed security interests, we interpret section 9.312(e) of the U.C.C. to adopt the relation-back position so that the first-to-file rule awards priority even to an advance made after an intervening security interest. See Tex.Bus. & Com.Code § 9.312(e)(1) and Example 4 (1968) (Tex.U.C.C.); Cohen, The Future Advance Interest Under the Uniform Commercial Code: Validity and Priority, 10 B.C.Ind. & Com.L.Rev. 1, 13 (1968); Comment, Priority of Future Advances Lending Under the Uniform Commercial Code, 35 U.Chi.L.Rev. 128, 133-34 (1967). The 1972 amendments to the U.C.C., adopted by Texas in 1973, effective in 1974, explicitly adopted the relation-back position for future advances. See Tex.Bus. & Com. Code § 9.312(g) (Supp.1976) (Tex.U.C.C.). Although no Texas cases confirmed the pri- or U.C.C. provisions’ adoption of the relation-back doctrine, the doctrine was consistently upheld in pre-Code Texas cases involving future advances. See Freiberg v. Magale, 70 Tex. 116, 7 S.W. 684, 685 (1888); Crabb v. William Cameron & Co., 63 S.W.2d 367, 368 (Tex.Com.App.1933, judgm’t adopted); Coke Lumber & Mfg. Co. v. First National Bank, 529 S.W.2d 612, 615 (Tex. Civ.App.—Dallas 1975, writ ref’d). See also Wallenstein & St. Claire, supra at 53-54 n.214. Under Texas law, Kimbell retained a superior lien to Republic, and the SBA, as Republic’s assignee, held an inferior state lien.
Priority Under Federal Law
The SBA asserts that, despite its poor showing under state law, under federal law it has a claim superior to Kimbell’s.9 The SBA asserts the federal common law priority rule of “first in time, first in right” and the peculiar patina that federal courts have placed on that rule specifying that only “choate” nonfederal liens may qualify as “first in time.” We conclude that the “choateness” rule of federal common law does not apply here.
Understanding the SBA’s argument requires a review of the development of the federal common law of priority. The source of much of federal priority law is the congressional declaration awarding the United States priority for the payment of its debts from certain insolvents.10 In 31 U.S.C. § 191 (1970) (or Revised Statutes § 3466 as it is more commonly known), Congress requires that in settling the affairs of certain insolvents “the debts due to [499]*499the United States shall be first satisfied.” Section 3466 had been read as only granting the United States, as an unsecured creditor, a priority against other unsecured creditors, see Kennedy, The Relative Priority of the Federal Government: The Pernicious Career of the Inchoate and General Lien, 63 Yale L.J. 905, 909-11 (1954), thus recognizing the integrity of pre-existing liens. But in Spokane County v. United States, 279 U.S. 80, 49 S.Ct. 321, 73 L.Ed. 621 (1929), the Supreme Court concluded that the priority granted the United States would defer only to specific and perfected (“choate”) liens prior in time. 279 U.S. at 93-95, 49 S.Ct. 321. To further protect the United States’ priority under section 3466, the Supreme Court ruled that whether a lien was choate involved a matter of federal law, see United States v. Waddill, Holland & Flinn, Inc., 323 U.S. 353, 65 S.Ct. 304, 89 L.Ed. 294 (1945), thus preventing states from divesting the United States of priority by adopting their own definitions of what constituted a choate state lien. Later the Supreme Court narrowly defined what could qualify ' as a choate lien,11 effectively assuring absolute priority to United States claims under section 3466. See Plumb, Federal Liens and Priorities—Agenda for the Next Decade, 77 Yale L.J. 228, 230 (1967); Kennedy, From Spokane County to Vermont: The Campaign of the Federal Government Against the Inchoate Lien, 50 Iowa L.Rev. 724, 736 (1965); Burroughs, The Choate Lien Doctrine, 1963 Duke L.J. 449, 452. See generally, Lacy, Effect of Federal Priority and Tax Lien Legislation on Creditors of Vendors and Purchasers, 50 Ore.L.Rev. 621, 625-31 (1971). Our case does not require the application of section 3466, since O.K. is not an insolvent, but the SBA invokes the choateness doctrine spawned by section 3466 to claim priority.
The SBA bases its argument on judicial extension of the choateness doctrine to determine priority for other federal liens. Although the federal tax statute accorded the United States a lien for taxes only—making no mention of priority for federal tax liens, see 26 U.S.C. § 6321 (1970)—in United States v. Security Trust & Savings Bank, 340 U.S. 47, 71 S.Ct. 111, 95 L.Ed. 53 (1950), the Supreme Court held that the choateness principles of section 3466 were equally applicable when a federal tax lien was competing for priority with a state lien. The purpose of the tax lien statute was to assure prompt and certain collection of taxes from tax delinquents; this purpose required a rule similar to that prevailing with collections under section 3466. 340 U.S. at 51, 71 S.Ct. 111. Other federal courts, without questioning whether the reasons for extending the choateness doctrine of section 3466 to tax liens justified its extension to other liens, have applied the doctrine to bestow overriding priority on other federal liens. See, e. g., T. H. Rogers Lumber Co. v. Apel, 468 F.2d 14 (10th Cir. 1972) (FHA mortgage lien); United States v. Oswald & Hess Co., 345 F.2d 886 (3d Cir. 1965) (SBA mortgage lien); In re Lehigh Valley Mills, Inc., 341 F.2d 398 (3d Cir. 1965) (SBA security interest). See also, Plumb, Federal Liens & Priorities—Agenda for the Next Decade, 77 Yale L.J. 228, 286-87 (1967). The SBA asks us to accord it this superior status in this ordinary commercial transaction far removed from the doctrine’s origins by arguing that the choateness doctrine is an inevitable consequence of applying federal law; but as our study reveals, the choateness concept is a judicial creation distinguishable from the well-recognized federal rule of “first in time, first in right.” See Texas Oil & Gas Corp. v. United States, 466 F.2d 1040, 1045 (5th Cir. 1972); Plumb, [500]*500supra at 230. History in this area does not permit us to enshrine without analysis the status sought by the SBA. Viewing the choateness doctrine independently, strong policy reasons militate against its application in this context.
First, the interests supporting the Supreme Court’s extension of section 3466’s criteria to tax liens in Security Trust do not support a similar extension to liens arising from SBA garden-variety commercial loans or guaranties. The choateness doctrine reflects a judicial recognition of the self-preservation prerogative of the sovereign. Taxes are its lifeblood, and the choateness doctrine recognizes and protects that vital flow. Delinquent taxes make the United States an involuntary creditor of the taxpayer, often ranged against other substantial commercial creditors and state tax creditors. By the time the United States becomes aware of its status and files its tax lien, it may well—absent self-help—find itself standing at the end of the state priority line. The Supreme Court’s extension of the choateness doctrine protected the collection of taxes and gave the United States, a sovereign, a measure of relief from its involuntary-creditor status. When the United States, however, in its less-exalted capacity as SBA, serves as a surrogate commercial lender or guarantor, it enters the commercial credit scheme voluntarily. These circumstances afford it an opportunity to evaluate the credit risks, to examine the interests of other creditors, and to exact such security as the circumstances and policy of the program dictate. See Plumb, The Relative Priority of Federal and Business Claims: Yesterday, Today and Tomorrow, 27 Bus.Lawyer 1195, 1217 (1972); Comment, The Priority of Federal Claims: Selected Problems and Theoretical Considerations, 24 Case W.L.Rev. 521, 534-35 (1973); Comment, The Relative Priority of SBA Liens: An Unreasonable Extension of the Federal Preference, 64 Mich.L.Rev. 1107, 1128-29 (1966). As a quasi-commercial lender, SBA (U.S.A.) does not require, and should not be accorded, the special priority which it compels as sovereign, so long as it complies with Congress’ admonition that it make loans which are “of such sound value or so secured as reasonably to assure repayment.” 15 U.S.C. § 636(a)(7) (1970). See Comment, The Relative Priority of SBA Liens: An Unreasonable Extension of the Federal Preference, supra at 1119.
Second, in a related concern, the importance of taxes to the functioning of government merits the extraordinary priority accorded them by the judge-made “choateness” doctrine. The Supreme Court has long recognized that section 3466 is informed by the importance of securing adequate revenue to sustain the public burdens and discharge the public debts. See United States v. Moore, 423 U.S. 77, 81-82, 96 S.Ct. 310, 46 L.Ed.2d 219 (1975); United States v. Emory, 314 U.S. 423, 426, 62 S.Ct. 317, 86 L.Ed. 315 (1943); United States v. State Bank of North Carolina, 6 Pet. 29, 35, 8 L.Ed. 308, 310 (1832). Consequently it has transferred that respect for revenue-protecting measures to the tax-lien statute. See Security Trust, supra. On the other hand, the SBA program is a supplement to commercial loan operations, certainly less central to the proper functioning of the national government and less deserving of the extraordinary priority accorded by the choateness doctrine.
Third, granting the SBA an exceptional priority pursuant to the choateness doctrine is inconsistent with the congressional declaration of policy pursuant to its establishment of the SBA. In 15 U.S.C. § 631 (1970), Congress declares that the purpose of the SBA assistance program is “to assist in the establishment, preservation, and strengthening of small business concerns . .” If the SBA may belatedly buy into loans and so assert liens superior to those of prior secured creditors, every sane potential creditor of small business will shun potential debtors of the SBA as anathema or extract promises that the debtor will not seek SBA assistance. What secured creditor will extend credit on collateral that may only serve to increase the security of a future SBA loan? Such a legal posture scarcely assures a steady flow of capital into necessitous small business.
[501]*501Finally, logical symmetry urges rejection of the SBA’s effort to extend the choateness doctrine to this context. The primary thrust of the SBA’s argument is that because section 3466’s choateness doctrine was extended to tax liens it should be extended to SBA contractual liens. Yet in the Federal Tax Lien Act of 1966 Congress substantially pared the applicability of the choateness doctrine by recognizing that certain state lien interests, including security interests, could attain priority over tax liens. See 26 U.S.C. § 6323 (1970). See generally, Coogan, The Effect of the Federal Tax Lien Act of 1966 Upon Security Interests Created Under the Uniform Commercial Code, 81 Harv.L.Rev. 1369 (1968). Why should the choateness doctrine bestow priority on an SBA contractual lien when a United States tax lien, more in need of the protection of the choateness doctrine, commands no such priority? Connecticut Mutual Life Ins. Co. v. Carter, 446 F.2d 136, 139 (5th Cir.), cert. denied, 404 U.S. 857, 92 S.Ct. 104, 30 L.Ed.2d 98 (1971); Ault v. Harris, 317 F.Supp. 373, 375 (D. Alaska), aff’d and opinion adopted, 432 F.2d 441 (9th Cir. 1970). See Note, 3 Rutgers Camden L.Rev. 592, 597 (1972).12 In the absence of any congressional directive to extend the choateness doctrine13 and in our role as judicial custodians of the doctrine, we decline to extend it further in this Circuit.
The SBA argues that circuit courts have already concluded that the choateness doctrine applies to mortgage liens, so it should apply here in the virtually identical situation of a federal contractual lien competing against state liens. It is true that a number of courts, including ours, have concluded that the federal “first in time, first in right” approach to priority applies to [502]*502federal mortgage liens. See United States v. Roessling, 280 F.2d 933 (5th Cir. 1960) (mortgage lien under Emergency Relief Appropriation Act of 1935); United States v. General Douglas MacArthur Senior Village, 470 F.2d 675 (2d Cir. 1972) (HUD mortgage lien); Director of Revenue v. United States, 392 F.2d 307 (10th Cir. 1968) (SBA mortgage lien); United States v. County of Iowa, 295 F.2d 257 (7th Cir. 1961) (Reconstruction Finance Corp. mortgage lien); Southwest Engine Co. v. United States, 275 F.2d 106 (10th Cir. 1960) (SBA chattel mortgage lien). Those cases are not necessarily authority for adoption of the choateness doctrine here, however, for in each case the application of the “first in time, first in right” doctrine, without using the concept of choateness, could have given priority to the federal liens because each competing state lien arose after the federal lien. See Roessling, supra at 935; General Douglas MacArthur Senior Village, supra at 677; Director of Revenue, supra at 313; County of Iowa, supra at 257-58; Southwest Engine Co., supra at 107. See also, Plumb, Federal Tax Liens & Priorities—Agenda for the Next Decade, 77 Yale L.J. 228, 287 n. 368 (1967); Comment, The Relative Priority of SBA Liens: An Unreasonable Extension of the Federal Preference, 64 Mich. L.Rev. 1107, 1128 (1966). Only the Third Circuit has applied the choateness doctrine to give priority to federal contractual liens when an unvarnished “first in time, first in right” approach would have given priority to the state claims. See United States v. Oswald & Hess Co., 345 F.2d 886 (3d Cir. 1965) (SBA mortgage lien); In re Lehigh Valley Mills, Inc., 341 F.2d 398 (3d Cir. 1965) (SBA mortgage lien). But there the Third Circuit assumed without analysis that “choateness” was part and parcel of the federal law. Our examination of the history of the choateness doctrine and the policy arguments against its extension to circumstances when the United States acts as lender persuade us to reject the Third Circuit’s approach and hold that the choateness doctrine does not apply to give priority to the SBA’s contractual lien in the absence of insolvency.14
Despite our decision that the choateness doctrine alone does not give the [503]*503SBA priority, the question the choateness doctrine addresses still remains: how does a federal court determine when a state lien has arisen so that it may decide whether the state or the federal lien is “first in time?” Whatever the answer to that question may be in other contexts,15 in the context of competing state security interests arising under the U.C.C., we conclude that liens perfected under the UCC qualify to compete against federal liens under the federal “first in time, first in right” priority rules.16 The UCC carefully prescribes the steps necessary to perfect a security interest. Perfection under the UCC provides many of the assurances of the existence of a lien required by the choateness doctrine— identity of the debtor, identity of the lien-holder, and identity of the property serving as collateral. Further, the UCC embodies rules of nationwide applicability—all states but Louisiana have adopted it—assuring that federal contractual liens will not be subject to the idiosyncracies of particular state laws. Cf. First National Bank v. SBA, 429 F.2d 280, 286 (5th Cir. 1970). The context provides our final reason: perfection under the UCC provides protection to the secured creditor against later-filed claims of other creditors; in the absence of congressional mandate or persuasive policy reasons to the contrary, it should similarly protect secured creditors against later arising federal contractual liens.
Even given our conclusions that the choateness doctrine does not apply here and that perfection under the UCC will qualify a lien as “first in time,” Kimbell must still establish that its lien was “first in time” under federal law. Its task is complicated because, although Kimbell had a perfected lien on the collateral, the indebtedness the lien secured results from future advances made after Republic made its loan to O.K. When the SBA bought into Republic’s loan in 1971, it bought Republic’s lien and for purposes of federal priority under “first in time, first in right,” the SBA’s lien “attached” when Republic’s lien arose in 1969. See United States v. Eklund, 369 F.Supp. 1052, 1054-55 (S.D.Ill.1972). Under Texas law, as we have seen, the lien securing future advances dates from Kimbell’s prior security interest. Does Kimbell’s lien retain that date under federal common law and thus remain prior in time to the Republic-SBA lien?
Perhaps because of the pervasiveness of the choateness doctrine, we have found no federal case discussing the substantive content of the “first in time, first in right” rule with regard to future advances. Faced with the necessity of fashioning a federal common-law rule because of congressional silence on the subject, see Clearfield Trust Co. v. United States, 318 U.S. 363, 376, 63 S.Ct. 573, 87 L.Ed. 838 (1943), we grapple with the problem by first examining the approach taken by the states.
Prior to the Uniform Commercial Code, the states adopted diverse rules on whether an optional (as opposed to an obligatory) future advance would relate back to take priority from the date of the original security agreement. The majority rule was that optional advances made before the advanc[504]*504ing creditor received actual notice of an intervening lien related back to the date of the original security interest. See Cohen, The Future Advance Interest Under the UCC: Validity & Priority, 10 B.C.Ind. & Comm.L.Rev. 1, 12 (1968); 59 C.J.S. Mortgages § 230(1) (1949); 55 Am.Jur.2d Mortgages § 352 (1971). A minority of jurisdictions adopted what was known as the Michigan rule in which, although the prior lien was effective to secure the future advance, the lien was effective only from the date the future advance was made. Intervening encumbrances took priority over subsequent future advances. Cohen, supra at 12-13. Another minority view, based on older English precedent, .held that optional future advances related back regardless of actual notice of intervening liens “for it was the Folly of the second Mortgagee, with Notice, to take such security.” Gordon v. Graham, 22 Eng.Rep. 502, 2 Eq.Ca.Abr. 598 (1716). See Cohen, supra at 11. As we have seen, the ubiquitous U.C.C., at least with respect to competing security interests perfected by filing, adopted the third rule. See, e. g., Tex.Bus. & Com.Code § 9.312(e)(1) (1968) (Tex.U.C.C.).
Our brief survey of American jurisprudence evidences at least this: the trend of thought in American law rejects the Michigan rule and allows future advances secured by an earlier security agreement to take priority from the date of the earlier security agreement under some circumstances. We believe that federal common law should recognize this legal principle.17 Cf. United States v. State of Alabama, 313 U.S. 274, 61 S.Ct. 1011, 85 L.Ed. 1327 (1941) (inchoate tax lien that became choate after United States purchased property gave due notice of liability and, when amount of tax was certain, related back to day lien imposed). Given that, however, we need go no further in crafting federal common law for this' case18 because under either the actual notice rule or the U.C.C. rule Kim-bell’s lien related back to its prior security agreement and was prior in time to the SBA’s lien.
Kimbell’s future advances relate back to and have the priority of its original security agreements with O.K. because at the time of the future advances Kimbell had no notice of the SBA’s lien. Thus, under the stricter “actual notice” rule for relation back, Kimbell had no notice of the SBA’s intervening interest. It is true that Kim-bell was aware of Republic’s lien and—so the record suggests—the SBA’s guaranty of the loan the lien secured.19 Yet under Texas law—the U.C.C.—this notice could not affect Kimbell’s decision whether to ad[505]*505vanee funds because under state law its advances were secured by and took the priority of the 1966 and 1968 security agreements. It was only when the SBA bought into the note in February 1971 that Kimbell could have actual notice of the existence of a federal lien and the application of federal law. At oral argument the United States conceded that before it bought into Republic’s note it had no lien. Without actual notice of another lien that could supersede the priority of its future advances under state law, Kimbell’s advancements are secured by and take the priority of the 1966 and 1968 security agreements.
In summary, the SBA’s purchase of 90% of Republic’s loan to O.K. vested it with Republic’s lien, and, in measuring priority under federal law, the SBA’s lien attached when Republic’s lien arose in 1969. All of Kimbell’s future advances were made subsequent to Republic’s loan, but the future advances are secured by the 1966 and 1968 security agreements and take priority from those dates. Thus, Kimbell’s lien for inventory advances is prior in time to the SBA’s lien, and Kimbell has priority in the proceeds from the sale of the three O.K. Supermarkets.
