Plaintiff-Appellant Pan American Company (Pan Am) filed suit in district court challenging the validity of an amended bingo ordinance enacted by the Sycuan Band of Mission Indians (Band) which imposed licensure and work permit requirements on Pan Am’s ongoing bingo operations. We affirm the district court’s dismissal of Pan Am’s complaint for jurisdictional defects based on failure to prove that the Band had waived tribal sovereign immunity.
*417 I.
The Sycuan Band of Mission Indians, a federally recognized Indian tribe, occupies a reservation in San Diego County. In November 1985, the Band and Pan Am entered into a federally-approved Management Agreement (“Bingo Agreement”) authorizing Pan Am to operate bingo games on the reservation. Under the terms of this Bingo Agreement, Pan Am agreed to construct and finance a Bingo facility on the Band’s land, and then manage, operate, and maintain the Band’s Tribal Bingo Enterprise (“Bingo Enterprise”) exclusively for fifteen years. As compensation for its operation of the Bingo Enterprise, Pan Am received a percentage of the net operating profits from the bingo games. The Bingo Agreement also contained an arbitration clause for resolving disputes between the parties.
For a little more than a year, both the Band and Pan Am enjoyed the fruits of the Bingo Enterprise. For the Band, it provided needed revenue for tribal government operations and services, as well as creating employment opportunities for members of the reservation community. Pan Am, for its part, also received substantial financial benefits from its operation of the Bingo Enterprise. Relations between the Band and Pan Am became strained, however, in April 1987 when the Band’s Tribal Council enacted an “Amended Ordinance Licensing and Permitting the Management of the Tribal Bingo Enterprise and Its Employees on the Sycuan Indian Reservation” (Amended Bingo Ordinance or Ordinance). Seeking to raise revenue for the support of tribal governmental services and protect the integrity of the Tribal Bingo Enterprise, the Amended Bingo Ordinance imposed licensure and work permit requirements on bingo game operators. For Pan Am, application and license fees under the Ordinance amounted to $80,000.
Pan Am deemed the Band’s enactment of the Amended Bingo Ordinance to be a breach of the Bingo Agreement and commenced a two-prong attack on the Band’s enforcement of the Ordinance. In addition to filing a demand for arbitration pursuant to the Bingo Agreement’s arbitration clause, Pan Am also filed a breach of contract action in the district court. 1
After an arbitrator dismissed Pan Am’s claims as nonarbitrable in late August 1987, Pan Am filed an amended complaint in the district court seeking declaratory, injunctive, and monetary relief for the Band’s enforcement of the Amended Bingo Ordinance which allegedly breached the Binge Agreement and deprived Pan Am of statutorily protected rights under 25 U.S.C. §§ 81 and 1302. Rather than answering Pan Am’s complaint, the Band filed a motion to dismiss for lack of personal and subject matter jurisdiction and failure to state a claim. See F.R.Civ.P. 12(b)(1), (2), and (6). The Band based its 12(b)(1) and (2) motion to dismiss for lack of jurisdiction on the ground that the Band, as a sovereign tribal entity, enjoyed immunity from suit which it had not waived. In the alternative, the Band asserted that Pan Am’s complaint should be dismissed pursuant to F. R.Civ.P. 12(b)(6) for failure to state a claim since the Ordinance was a valid exercise of the Band’s sovereign authority, the enactment of which could not have constituted a breach of the Bingo Agreement.
By two-page order dated December 2, 1987, the district court dismissed Pan Am’s breach of contract claim for lack of jurisdiction “because defendant Band has not expressly waived its sovereign immunity to unconsented suit.” The court also ruled, as an alternative ground for dismissal, that Pan Am had failed to state a claim for breach of contract because the Band’s *418 Amended Bingo Ordinance was a valid exercise of its sovereign authority “and thus ... [could not be] a breach of contract for which plaintiff [Pan Am] is entitled to damages or declaratory or injunctive relief.” Finally, the court dismissed Pan Am’s statutory causes of action for failure to state legally sufficient claims.

Haisten v. Grass Valley Medical Reimbursement Fund, Ltd.,
III.
Indian tribes have long been recognized as possessing common-law immunities from suit co-extensive with those enjoyed by other sovereign powers including the United States as a means of protecting tribal political autonomy and recognizing their tribal sovereignty which substantially predates our Constitution.
See, e.g., Santa Clara Pueblo v. Martinez,
Thus, since the issue of tribal sovereign immunity is jurisdictional in nature,
Puyallup III,
Pan Am’s waiver claim rests entirely on the Bingo Agreement’s arbitration clause. Whether or to what extent this arbitration clause constituted a waiver of the Band’s tribal sovereign immunity turns on the terms of that clause.
Santa Clara Pueblo
commands that waiver may only be found if the clause unequivocally and expressly indicates the Band’s consent to waive its sovereign immunity.
*419 [i]n the event a dispute arises between its parties ... either party may seek arbitration of said dispute and both parties do hereby subject themselves to the jurisdiction of the American Arbitration Association and do agree to be bound by and comply with its rules and regulations as promulgated from time to time.
Pan Am reads this clause as an explicit waiver of the Band’s sovereign immunity since “a submission to arbitration is a submission to judicial jurisdiction ... as a matter of definition.” Such a reading of the arbitration clause runs counter to not only the strong presumption against tribal waivers of immunity, but also generally accepted principles governing the interpretation of contractual arbitration provisions.
The Bingo Agreement’s arbitration clause simply does not contain that unequivocal expression of tribal consent to suit necessary to effect a waiver of the Band’s sovereign immunity. Absent an affirmative textual waiver in the terms of a contractual agreement or tribal constitution, federal courts have consistently declined to find tribal consent to federal jurisdiction.
Compare San Manuel Band,
Pan Am in essence asks this court to imply a waiver of tribal sovereign immunity from the text of the arbitration clause since this provision, Pan Am contends, would otherwise “merely be a trap for the unsuspecting” and leave Pan Am without judicially enforceable remedies for the Band’s alleged breach of contract. Yet Indian sovereignty, like that of other sovereigns, is not a discretionary principle subject to the vagaries of the commercial bargaining process or the equities of a given situation.
USF & G,
Our decision in
United States v. Oregon,
*420
The conservation agreement at issue in
Oregon
arose from a longstanding dispute between the United States government, several states in the Pacific Northwest, and the Yakima tribe, over fishing rights in the Columbia River Basin. In 1968, the United States initiated an action against Oregon to protect the treaty fishing rights of all Indian tribes in the Basin area; shortly thereafter, the Yakima tribe intervened as a party plaintiff.
Unlike the intervenors in
Oregon,
however, the Band’s participation in Pan Am’s action can in no way be construed as consensual.
2
The Band has steadfastly denied the jurisdiction of both the arbitrator and the federal court to rule on the validity of the Amended Bingo Ordinance. In contrast, the Yakima Tribe’s intervention into an ongoing federal suit constituted express consent in
Oregon
since, when entering into that action, the tribe explicitly agreed to be bound by whatever resolution ordered by the district court.
See
While Oregon’s finding of waiver probably tests the outer limits of
Santa Clara
Pueblo’s admonition against implied waivers,
see Standing Rock,
IV.
Accordingly, in deference to Santa Clara Pueblo’s strong presumption against waivers of tribal sovereign immunity, we affirm the district court’s dismissal of Pan Am’s complaint as the Band did not effect a waiver of its tribal sovereign immunity by entering into the Bingo Agreement’s arbitration clause.
AFFIRMED.
Notes
. While Pan Am pursued its challenges to the Amended Bingo Ordinance, the parties agreed that Pan Am could receive a management license pendente lite upon payment of the disputed application and license fees ($80,000) to the registry of the district court. Pan Am paid the required fees and was subsequently issued a license. Pan Am continued to operate the tribal Bingo Enterprise until revocation of its management license by the Band in December 1987 over a dispute concerning attorney fees. The disposition of this $80,000 escrow account is the subject of a separate appeal. See Pan American Co. v. Sycuan Band of Mission Indians, No. 87-5783 (9th Cir. filed Feb. 17, 1988).
. Pan Am contends that the Band submitted to the jurisdiction of the court by including materials outside the pleadings when it filed its 12(b) motion to dismiss. It is clear from the record that those materials were submitted solely to establish that the arbitration clause did not constitute a waiver of the Band's tribal sovereign immunity, and were not submitted on the merits of the controversy. Materials outside the pleadings which relate to jurisdiction can be considered on a motion to dismiss for lack of jurisdiction.
