MEMORANDUM OPINION

THYNGE, United States Magistrate Judge.

INTRODUCTION

In this case, the court now considers defendants Formula Plus, Inc. and Does 1-10's ("Formula Plus") motion to dismiss pursuant to Fed.R.Civ.P. 12(b)(1), or, in the alternative, its motion to stay the proceedings pending arbitration.1 The parties completed briefing on these issues on September 8, 2010.2 For the reasons stated below, the motions are denied.3

BACKGROUND

On March 23, 2004, George Febish ("Febish") entered into a commission agreement with Formula Plus.4 The agreement was signed by Ronald Weber ("Weber"), President and CEO of Formula Plus. Weber is also an attorney.5 Under the terms of the agreement, Febish would be paid a "15% commission of the total purchase price ... for each gallon of the Formula Plus Fuel Treatment ("Treatment") sold to those clients secured by you or your assigns on behalf of the company."6 The duration of this agreement was 180 days in order to secure interest in the product in the country of Ghana.7

In April 2004, Paul Cohen ("Cohen") introduced Formula Plus to a "substantial oil refinery opportunity in the Republic of Ghana."8 Thereafter, Clark Esperance ("Esperance") and Cohen discussed using Formula Plus with the son of a regional Ghanaian king and negotiated a deal to sell the Formula Plus fuel treatment.9 Jan Gordon ("Gordon") and Febish assisted in finalizing the sale, and as a group, all four plaintiffs invested considerable time and effort into securing the deal between Formula Plus and Ghana.10

On July 20, 2004, Febish and Formula Plus signed a subsequent agreement that officially extended the term of appointment for Febish and his assigns (undesignated in the document) as the exclusive agent for Formula Plus in Ghana. The agreement contained the following provision: "[i]t is understood by the parties that this letter supercedes all previous agreements, written or oral, between the Company and the Agent relating to Ghana."11 Additionally, the agreement contained an arbitration clause providing, in part, "[a]ny dispute... shall be settled by final arbitration conducted in English in accordance with the American Arbitration Rules."12 This agreement was again signed by both Febish and Weber.

On October 1, 2005, an addendum to the commission agreement was executed again only by Febish and Weber. The first paragraph states, "[t]his Addendum to the Commission Agreement ("Agreement") of March 23, 2004 (as subsequently amended) between Mr. Ronald F. Weber, on behalf of Formula Plus and Mr. George Febish or his assigns shall become effective upon execution by the Parties." The addendum set forth the following commission distribution: 4.2% to BCP, Inc., 1.4% to George Febish, 1.4% to Jan Gordon, and 8.0% to Ghana In-Country Personnel.

Subsequently, on November 15, 2005, each plaintiff entered into a separate commission agreement with Formula Plus. Apparently, mistrust of Febish had developed regarding monetary distributions, and Cohen, Esperance, and Gordon requested separate commission agreements from Formula Plus to ensure their portion of the commission was fair and sent directly to them. The four individual documents are identical and begin with the following language:

The agreements note that the commission percentages changed so that each plaintiff was to receive 1% of the purchase price of each gallon of the Formula Plus fuel treatment.14 Plaintiffs signed their respective commission agreements. Weber executed each of the agreements as well. Above the signature lines is a statement that reflects the agreement was executed in Scottsdale, AZ and the respective city and state of each plaintiff: Marlton, N.J. for Febish; North Salem, N.Y. for Cohen; Los Angeles, CA for Gordon; and Willingboro, N.J. for Esperance.15

Subsequently, quantities of the Formula Plus fuel treatment were shipped to Ghana.16 In September 2009, Formula Plus, in writing, expressly repudiated all contractual obligations to plaintiffs under their individual commission agreements.17

STANDARDS OF REVIEW

Arbitration

When jurisdiction is challenged, the party asserting subject matter jurisdiction has the burden of proving its existence.18 Under Rule 12(b)(1), the court's jurisdiction may be challenged either facially, that is, based on the legal sufficiency of the claim, or factually, based on the sufficiency of jurisdictional facts.19 A motion to dismiss on the basis that the dispute must be arbitrated is a factual challenge.20

When there is a factual attack, the court is not "confine[d] to the allegations in the ... complaint, but [may] consider affidavits, depositions and testimony to resolve factual issues bearing on jurisdiction."21 Under that circumstance, "no presumptive truthfulness attaches to plaintiff's allegations, and the existence of disputed material facts will not preclude the trial court from evaluating for itself the merits of the jurisdictional claims."22

Arbitration disputes are governed by the Federal Arbitration Act ("FAA"), 9 U.S.C. §§ 1 et seq. Prior to compelling arbitration under the FAA, a court must first determine whether the parties have agreed to arbitrate.23 That determination is made by applying "ordinary state-law principles that govern the formation of contracts."24 Second, the dispute at issue must come within the scope of the arbitration agreement.25 Pursuant to the FAA and federal policy, there is a presumption in favor of arbitration "in determining whether the particular dispute falls within a valid arbitration agreement's scope."26

Choice of Law

This case involves parties from five states: Delaware, Arizona, New Jersey, New York, and California. Accordingly, the court must conduct a survey of the law of each state to determine which apply to this action. The first issue for resolution is which state law applies when a contract is silent on its face as to the choice of law.

In Delaware, when there is no reference to the choice of law in a contract, courts apply the "most significant relationship" test articulated in the RESTATEMENT (SECOND) OF CONFLICT OF LAWS to resolve conflict issues arising out of the interpretation and validity of contracts.27 The "most significant relationship" test is defined in § 188 of the Restatement:

The principles stated in § 6 of the Restatement are as follows:

Arizona takes an identical approach: "[i]n the absence of an explicit choice of law by the parties, the contractual rights and duties of the parties are determined by the local law of the state having the most significant relationship to the parties and the transaction."30 New York follows the same course: "[t]he Second Restatement, in addition to ... the place of contracting, offers four other factors to be considered in establishing this most significant relationship: the places of negotiation and performance; the location of the subject matter; and the domicile or place of business of the contracting parties."31 Additionally, New Jersey follows the Restatements conflict-of-law standard in contract actions whereby "the `most significant relationship' test ... focuses upon that state which has the most meaningful connections with the transaction and the parties in issue ... [and] [t]hese important contacts become relevant in the assessment of those basic considerations which determine ultimately the choice of law."32

California has a slightly different approach that does not invoke the Restatement's "most significant relationship test." Instead, California resolves the issue by statute. "Civil Code section 1646 determines the law governing contract interpretation notwithstanding the application of the governmental interest analysis to other choice-of-law issues."33 The statute provides: "[a] contract is to be interpreted according to the law and usage of the place where it is to be performed; or, if it does not indicate a place of performance, according to the law and usage of the place where it is made."34 Although California does not apply the Restatement, its statutory factors are similar.

Parol Evidence

In Delaware, "[i]f a contract is unambiguous, extrinsic evidence may not be used to interpret the intent of the parties, to vary the terms of the contract or to create an ambiguity."35 If the instrument is clear and unambiguous on its face, parol evidence may not be considered "to interpret it or search for the parties' intent...."36 The parol evidence rule provides that "[w]hen two parties have made a contract and have expressed it in a writing to which they have both assented as to the complete and accurate integration of that contract, evidence ... of antecedent understandings and negotiations will not be admitted for the purpose of varying or contradicting the writing."37

To ensure compliance with the parol evidence rule, the court first must determine whether the terms of the contract to be construed clearly state the parties' agreement.38 However, a contract is not rendered ambiguous simply because the parties disagree as to the meaning of its terms.39 "Rather, a contract is ambiguous only when the provisions in controversy are reasonably or fairly susceptible of different interpretations or may have two or more different meanings."40 Upon concluding that the contract clearly and unambiguously reflects the parties' intent, the court's interpretation of the contract must be confined to the "four comers" of the document.41

California law states: "[t]he parol evidence rule generally prohibits the introduction of extrinsic evidence—oral or written—to vary or contradict the terms of an integrated written instrument."42 According to this substantive rule of law, "when the parties intend a written agreement to be the final and complete expression of their understanding, that writing becomes the final contract between the parties, which may not be contradicted by even the most persuasive evidence of collateral agreements. Such evidence is legally irrelevant."43

New York and New Jersey follow a similar analysis of parol evidence. In New York, "[w]hen parties set down their agreement in a clear, complete document, their writing should as a rule be enforced according to its terms. Evidence outside the four comers of the document as to what was really intended but unstated... is generally inadmissible to add to or vary the writing."44 It is well settled that "extrinsic and parol evidence is not admissible to create an ambiguity in a written agreement which is complete and clear and unambiguous upon its face."45 In New Jersey, "admission of evidence of extrinsic facts is not for the purpose of changing the writing ... [such] evidence is ... only for the purpose of interpreting the writing to aid in determining the meaning of what has been said, not for the purpose of modifying or enlarging or curtailing its terms."46 "Extrinsic evidence of one party's alleged contractual intent is not admissible to alter or contradict express and unambiguous terms of a written agreement."47

Arizona law differs slightly from the other four states as it generally looks to the contracting parties intentions when interpreting a contract.48 "The court must decide what evidence, other than the writing, is admissible in the interpretation process, bearing in mind that the parol evidence rule prohibits extrinsic evidence to vary or contradict, but not to interpret, the agreement."49 First, the court considers evidence to determine the extent of integration, illuminate the meaning of the contract language, or demonstrate the parties' intent.50 The second step involves "finalizing" the court's understanding of the contract, and here "the parol evidence rule applies and precludes admission of the extrinsic evidence that would vary or contradict the meaning of the written words."51

Most notably, Arizona lacks the prerequisite of ambiguity that the other four states share in common. The Arizona Supreme Court states: "[w]e are hesitant to endorse ... the often repeated and usually over-simplified construct that ambiguity must exist before parol evidence is admissible."52 The proffered policy is that "the ambiguity determination distracts the court from its primary objective—to enforce the contract as intended by the parties."53 The rule in Arizona "is that the judge first considers the offered evidence and, if he or she finds that the contract language is `reasonably susceptible' to the interpretation asserted by its proponent, the evidence is admissible to determine the meaning intended by the parties."54

DISCUSSION

Formula Plus argues that this dispute is governed by the FAA because the parties entered into a valid arbitration agreement, embodied in a commission agreement, which specifically provides that "[a]ny dispute ... shall be settled by final arbitration conducted in English in accordance with the American Arbitration Rules." Plaintiffs counter that the arbitration agreement does not operate because it is not embodied in the latest commission agreements signed by Weber and each plaintiff individually.

The FAA does not require arbitration unless the parties have contractually agreed to arbitrate. The court is convinced that in the present matter, the parties entered into valid separate commission agreements, but did not agree to arbitrate their claims due to the absence of an arbitration provision in the commission agreements signed on November 14, 2005.

The evidence shows that, unlike prior commission agreements, in the last commission agreement Formula Plus and plaintiffs were direct parties.55 Further, each plaintiff was offered "a commission equal to 1% of the purchase price of each gallon of the Formula Plus Fuel Treatment ("Treatment") sold by Formula Plus."56 Their signatures at the end of the agreement confirm their acceptance. Directly above the signature line, the commission agreement reads: "[t]he Parties do hereby agree to the provisions contained in this Agreement."57 Both Weber and plaintiffs' respective signatures appear on the same page of the newly drafted individual commission agreements. The necessary elements of offer, acceptance, and consideration are therefore established for the creation of a valid contract between Formula Plus and each plaintiff.

The court, having concluded that the parties entered into a valid contract (i.e., the individual commission agreements of November 14, 2005), must now decide whether to allow extrinsic evidence to determine if the parties intended to arbitrate any disputes as contained in the previous agreements and the addendum. Plaintiffs correctly note that the separate commission agreements do not contain any choice of law provision.58 Formula Plus asserts that Arizona law applies, but that language does not appear in the individual commission agreements.59 Neither party claims that the laws of the Republic of Ghana should operate. Furthermore, it is reasonable to infer that the majority of the work necessary to secure the sale of the fuel treatment is performed in the home state of each plaintiff.60 In the end, however, the result remains the same regardless of which state law would apply to the consideration of parol evidence related to the individual commission agreements.

Except for Arizona, the other jurisdictions strictly adhere to the parol evidence rule that, absent ambiguity, extrinsic evidence is not considered in determining the meaning of a written contract.61 Here, the November 14 commission agreements are not ambiguous. Therefore, extrinsic evidence cannot be used to construe their meaning. The provision in the final commission agreements, "shall supersede all previous Agreements," is not open for interpretation by parol evidence because it would contradict, alter, expand, or distort the plain meaning of the written words. The meaning of supersede, "[t]o annul, make void, or repeal by taking the place of,"62 is similarly not subject to interpretation. There is no arbitration provision in the individual commission agreements. There is no incorporation of preceding agreements including the July 20, 2004 agreement, which originally contained an arbitration provision. When Formula Plus wanted to incorporate prior agreements, as considered in the first paragraph of the Addendum of October 1, 2005, it did so by clear, precise language.63 Accordingly, the parties did not agree to arbitrate in the November 14 commission agreements.

Applying Arizona's parol evidence rule results in the same conclusion. In that jurisdiction, the introduction of parol evidence is only allowed to determine the intent of the parties when there exists a dispute as to the meanings of words in the contract.64 Similar to the other jurisdictions, parole evidence cannot be used to vary or contradict the clear meaning of the written terms. Here, there is a complete absence of any mention of arbitration. There is no language requiring court interpretation to find the parties' intent. There are no contract terms "reasonably susceptible" to the interpretation proposed by Formula Plus. Moreover, the language "shall supersede all previous Agreements" is not subject to nor requires interpretation with the aid of parol evidence. Formula Plus' argument would require the court to add terms that would modify "the meaning of the written words" which is inconsistent with Arizona law.65 Finally, the separate November 14 agreements are contracts directly between Formula Plus and plaintiffs, rather than through Febish; provide specific and different commission rates for each plaintiff than previously allotted; and require the commission payment to flow directly from Formula Plus to each plaintiff. These modifications materially alter the previous agreements and serve as a clear indication that the parties entered into entirely new contracts without incorporation of any preceding agreements.

Because the parties did not contract to arbitrate, this matter is not subject to the FAA and this court has subject matter jurisdiction. In so finding, the court need not address Formula Plus' alternative motion to stay the proceedings pending arbitration.

CONCLUSION

Based upon the foregoing analysis, Formula Plus' motion to dismiss (D.I. 12) for lack of subject matter jurisdiction pursuant to Fed.R.Civ.P. 12(b)(1) is DENIED. Formula Plus' alternative motion to stay proceedings pending arbitration is DENIED as MOOT.
