Lоnnie Brown, Nettie Brown, Jerry Brown, and Pat Brown (“the Browns”) appeal from an order staying proceedings and compelling arbitration of their claims against Citigroup Global Markets, Inc., formerly Smith Barney (“Smith Barney”), G.E. Life & Annuity Insurance Company (“GE”), and Pacific Life Insurance Company (“Pacific”) (collectively “Appellees”).
I
The Browns are investors in, and beneficiaries of, Smith Barney securities brokerage accounts. Smith Barney’s representative, Patrick Holt (“Holt”), managed these accounts, investing in variable annuities from GE and Pacific, as well as a variety of stocks.
Upset with Holt’s investment decisions, the Browns sued Smith Barney, GE, Pacific, and Holt in Louisiana state court (“the State Action”), alleging fraud, negligence, and breach of various common law and statutory duties. The defendants removed the State Action to federal district court. Soon thereafter, Smith Barney, with inter-venors GE and Pacific, filed two separate civil actions against the Browns in federal court (“the Federal Actions”): one against Lonnie and Nettie Brown, and one against Jerry and Pat Brown. Both lawsuits sought an order compelling arbitration of the Browns’ claims pursuant to the Federal Arbitration Act (“FAA”), 9 U.S.C. §§ 1-16, based on arbitration clauses that were included in Smith Barney’s client agreement with the Browns. Appellees also moved for a stay pending arbitration in the State Action рursuant to section 3 of the FAA. 1
*390 Soon thereafter, Smith Barney and Pacific moved to compel arbitration under the FAA in the Federal Actions. Around this time, the district court consolidated the State Action with the Federal Actions. Smith Barney, with Pacific joining, then filed a reply in support of the motions to compel arbitration and to stay the consolidated action, arguing for a stay based upon section 3.
Contemporaneously with this flurry of activity, the Browns moved to remand the State Action as untimely removed. They also moved to dismiss the Federal Actions and the complaints in intervention on jurisdictional grounds, asserting that Holt, a non-party to the Federal Actions, is an indispеnsable party under Federal Rule of Civil Procedure 19 whose joinder would destroy diversity of citizenship. They also argued that the court should abstain from exercising jurisdiction. The district court remanded the State Action but denied the motion to dismiss the Federal Actions. Rather than consider the issue of arbitra-bility, however, the court stayed the Federal Actions pending the outcome in the remanded State Action because “[i]t would be a waste of judicial resources and of the parties’ time and treasure if both federal and the state court were to proceed simultaneously in these cases.... ”
The Appellees moved in the Federal Actions to alter or amend the stay order, arguing that the policy favoring arbitration required lifting the stay and ordering arbitration despite the threat of piecemeal litigation in state and federal court. The district court agreed, vacating the stay as improvidently issued and ordering additional briefing addressing the issue of arbi-trability.
After receiving briefing, the district court addressed the “sole issue to be decided” in the Federal Actions — arbitrability of the Browns’ claims against the Appel-lees. The district court concluded that the Browns were bound by an arbitration clause in their client agreements and were compelled to arbitrate their claims against Smith Barney. It also concluded that the аctions of Smith Barney, intervenors GE and Pacific, and Holt were “inextricably intertwined” because “[tjhere is no way to bring actions against either [GE or Pacific] without considering the actions of Smith Barney and its employee, Patrick Holt.” Applying equitable estoppel, the court then ordered arbitration of the claims against Pacific and GE as well. Without offering a basis for its authority, the district court then “stay[ed] the Browns’ actions against all the defendants within its jurisdiction, to include Smith Barney, Pacific, and GE pending binding arbitration.”
II
The Browns appeal from the district court’s order compelling arbitration and staying proceedings. Appellees contend that this court does not have jurisdiction to hear the Browns’ appeal. As always, we have “jurisdiction to determine our own jurisdiction.”
Cerveceria Cuauhtemoc Moctezuma S.A. de C.V. v. Mont. Beverage Co.,
Section 16(b) of the FAA. forbids appeals of interlocutory orders granting a stay under section 3 or directing arbitration to proceed under section 4.

Howev
*391
er, “a final decision with respect to an arbitration” is appealable under section 16(a)(3). A decision is considered final under the FAA if it “ends the litigation on the merits and leaves nothing more for the court to do but execute the judgment.”
Green Tree Fin. Corp.-Ala. v. Randolph,
In this case, the district court granted the sole remedy sought by the plaintiffs in the Federal Actions — an order compelling arbitration. Although the district court did not dismiss the ease, there was nothing left for the court to do but execute the judgment.
See Am. Heritage Life Ins. Co. v. Orr,
Appellees argue that the stay in this case rendered the order non-appealable under 9 U.S.C. § 16(b)(1). See 9 U.S.C. § 16(b)(1) (specifying that an appeal may not be taken from an interlocutory order granting a stay under 9 U.S.C. § 3). That it stayed the Browns’ actions within its jurisdiction is, however, of no moment unless the stay was of proceedings before the district court under 9 U.S.C. § 3. Here, the district court did not state the authority for its stay, and it is impossible to discern from the record whether the district court thought its stay was issued pursuant to section 3. Although the only authority cited in the parties’ motions was section 3, the сourt’s terse statement that it was staying “the Browns’ actions against all the defendants within its jurisdiction” is subject to multiple plausible interpretations. 3
*392
We must speculate upon the authority for the stay based upon brief language in the order, the numerous overlapping and multifarious motions of the parties, and our interpretation of the voluminous district court filings in three separate eases— cases that have been consolidated and separated, removed and remanded. Under such circumstances, remand to the district court for clarification is often required.
See, e.g., Joseph v. City of New Orleans,
Remand is unnecessary in this case. Based upon our independent review of the record, we conclude that the stay could not have been issued pursuant to 9 U.S.C. § 3.
See Gulf Guar. Life Ins. Co. v. Conn. Gen. Life Ins.,
*393 We hold that the district court did not issue a section 3 stay and, furthermore, that the arbitration order is a final decision under Green Tree and 9 U.S.C. § 16(a)(3). Accordingly, the order is appealable.
Ill
Having determined our jurisdiction on appeal, we turn to the Browns’ contention that the district court erred by: (A) exercising jurisdiction over the Federal Actions; (B) refusing to abstain from exercising jurisdiction; (C) ruling that the arbitration agreement is valid and binding; and (D) ruling that the Browns’ claims against Pacific and GE are arbi-trable.
A
The Browns assert that the district court erred in denying their motion to dismiss the Federal Actions because Holt is an indispensable party whose joinder would destroy diversity jurisdiction.
6
We review the denial of a motion to dismiss for failure to join an indispensable party for an abuse of discretion.
HS Res., Inc. v. Wingate,
Under Rule 19, a person subject to process and whose joinder will not deprive the court of subject-matter jurisdiction must be joined if:
(1) in the person’s absence complete relief cannot be accorded among those already parties, or (2) the person claims an interest relating to the subject of the action and is so situated that the disposition of the action in the person’s absence may (i) as a practical matter impair or impede the person’s ability to protect that interest or (ii) leave any of the persons already parties subject to a substantial risk of incurring double, multiple, or otherwise inconsistent obligations by reason оf the claimed interest.
Fed.R.Civ.P. 19(a). If a person who qualifies under Rule 19(a) cannot be made a party because, for example, joinder would destroy subject-matter jurisdiction, a federal court must determine whether that person is “indispensable.” In making this determination, the court should consider:
*394 first, to what extent a judgment rendered in the person’s absence might be prejudicial to the person or those already parties; second, the extent to which, by protective provisions in the judgment, by the shaping of relief, or other measures, the prejudice can be lessened or avoided; third, whether a judgment rendered in the person’s absence will be adequatе; fourth, whether the plaintiff will have an adequate remedy if the action is dismissed for nonjoin-der.
Fed.R.Civ.P. 19(b). When assessing these factors, the relevant inquiry is whether “in equity and good conscience the action shall proceed among the parties before it, or should be dismissed, the absent person being thus regarded as indispensable.”
Id.; see Pulitzer-Polster v. Pulitzer,
The district court did not abuse its discretion in finding that Holt is not an indispensable party under Rule 19(b). The threat of piecemeal, inconsistent litigation of claims and issues, the Browns’ primary concern, is insufficiently prejudicial to render a party indispensable under Rule 19 given the oft-stated preference for arbitration under the FAA.
Snap-On Tools Corp. v. Mason,
B
The Browns argue that the district court should have abstained from exercising jurisdiction over the Federal Actions. They assert that the district court misapplied the abstention doctrine set forth in
Coloradо River Water Conservation District v. United States,
Under the
Colorado River
doctrine, a court may abstain from a case under “exceptional circumstances.”
Kelly Inv., Inc. v. Cont’l Common Corp.,
315
*395
F.3d 494, 497 (5th Cir.2002).
7
There are six factors for determining whether “exceptional circumstances” exist: (1) assumption by either state or federal court over a res; (2) relative inconvenience of the fora; (3) avoidance of piecemeаl litigation; (4) order in which jurisdiction was obtained by the concurrent fora; (5) extent federal law provides the rules of decision on the merits; and (6) adequacy of the state proceedings in protecting the rights of the party invoking federal jurisdiction.
Stewart,
The Browns’ sole argument in favor of abstention is that the state court may decide that the case against Holt is not arbitrable after the district court decided that the claims against Smith Barney are arbitrable. They assert that the possibility of piecemeal litigation, the third factor in the abstention analysis, required the district court to abstain from the exercise of jurisdiction. We found a similar argument unconvincing in
Snap-On Tools.
In that case, the plaintiffs-appellants argued that abstention was appropriate where certain state defendants would not participate in the arbitration because they were neither parties to the federal actions nor the arbitration agreement. We expressed doubt that the state court would determine the issuе of arbitrability differently from the federal court and also found that “some piecemeal litigation” is sometimes “the inevitable result of a congressional policy strongly favoring arbitration.”
Snap-On Tools,
The Browns attempt to distinguish this case from Snap-On Tools. They argue that abstention is warranted where the state court’s arbitrability determination may affect a party to the arbitration agreement, not a non-party as in Snap-On Tools. They assert that “Moses H. Cone only condones piecemeal litigation where one of the parties to the underlying dispute is not a party the arbitration agreement” and that Snap-On Tools did not decide this issue differently.
“Abstention from the exercise of federal jurisdiction is the exception, not the rule.”
Colo. River,
C
Even if the district court properly exercised jurisdiction, the Browns assert that the district court erred by compelling arbitration of their claims. They contend that their consent to arbitrate was vitiated by fraud and error and, furthermore, that the arbitration clause itself is a contract of adhesion.
8
We review the grant of a motion to compel arbitration
de novo. Webb v. Investacorp, Inc.,
“In adjudicating a motion to compel arbitration under the [FAA], courts generally conduct a two-step inquiry.”
Webb,
On аppeal, the Browns challenge only the validity of their consent to arbitrate. “Challenges to the validity of arbitration agreements ‘upon such grounds as exist at law or in equity for the revocation of any contract’ can be divided into two types.”
Buckeye Check Cashing, Inc. v. Cardegna,
— U.S. -,
Although the Browns argue fraud and error, they do not distinguish between their attacks on the validity of the client agreements and the arbitration clauses themselves. They assert only that they would not have entered into the client agreements containing the arbitration clauses if Holt had not misrepresented the terms of their investments. Where claims of error, fraud, or unconscionability do not specifically address the arbitration agreement itself, they are properly addressed by the arbitrator, not a federal court.
Primerica Life Ins. Co. v. Brown,
We may, however, address the Browns’ argument that the arbitration clauses themselves are contracts of adhesion and, therefore, unenforceable. The Browns rely primarily upon
Sutton’s Steel & Supply, Inc. v. BellSouth Mobility, Inc.,
In summation, a contract is one of adhesion when either its form, print, or unequal terms call into question the consent of the non-drafting party and it is demonstrated that the contract is unenforceable, due to lack of consent or error which vitiates consent. Accordingly, even if а contract is standard in form and printed in small font, if it does not call into question the non-drafting party’s consent and if it is not demonstrated that the non-drafting party did not consent or his consent is vitiated by error, the contract is not a contract of adhesion.
Id. at 10-11. Applying these principles, the Louisiana Supreme Court found no evidence that the plaintiff did not consent. The plaintiff in Aguillard signed the document and, according to the court, “a party who signs a written instrument is presumed to know its contents.” Id. at 17. The court also found no evidence that inequality in the parties’ respective bargaining positions vitiated consent “because the plaintiff could have avoided аrbitration and the contractual provisions as a whole by simply not signing the agreement.” Id. Finally, the court examined the arbitration agreement itself and found that the lower court, in following Sutton’s Steel and Simpson, “erred as a matter of law in declaring the arbitration clause adhesion-ary” because, inter alia, the print was not unreasonably small, the contract was only two pages, and the contract was mutually burdensome. Id. at 16-18.
The arbitration clauses in the Browns’ client agreements are not unconscionable and the district court did not err in finding them valid. As in Aguillard, the Browns were not forced to agree to the terms of those clauses. They could have avoided *398 arbitration by not engaging Smith Barney’s servicеs. There is nothing exceptional or burdensome about these clauses, and there is no reason to believe that the Browns did not knowingly and willingly accept their terms.
D
Provided the agreements are valid, the Browns do not dispute the arbitrability of their claims against Smith Barney. They argue, however, that the district court erred by estopping the Browns from asserting that the lack of a written arbitration agreement precluded arbitration of their claims against GE and Pacific. We review for abuse of discretion the district court’s use of equitable estoppel.
Grigson v. Creative Artists Agency, LLC,
Although arbitration is a matter of contract that generally binds only signatories, a party to an arbitration agreement may be equitably estopped from litigating its claims against non-parties in court and may be ordered to arbitration.
Id.
at 526 (citing
MS Dealer Serv. Corp. v. Franklin,
Although close, we conclude that the district court did not abuse its discretion in determining that the Browns were estopped under
Grigson’s
second prong from asserting that a lack of a written arbitration agreement precluded arbitration. The district court’s finding that there was no way to bring actions against GE and Pacific without considering the actions of Smith Barney and Patrick Holt, is not patently incorrect.
10
Whether and
*399
how GE and Pacific defrauded or breached duties owed to the Browns depends, in some part, upon the nature of tortious acts allegedly committed by Holt and Smith Barney — acts that would be covered by the arbitration agreement — as well as any tor-tious acts by GE and Pacific.
See Hill v. GE Power Sys., Inc.,
IV
For the reasons stated, we AFFIRM the district court’s order staying proceedings and compelling arbitration of the Browns’ disputes against Smith Barney, Pacific, and GE.
Notes
. "The [FAA] provides two parallel devices for enforcing an arbitration agreement: a stay of litigation in any case raising a dispute referable to arbitration, 9 U.S.C. § 3, and an affirmative order to engage in arbitration, § 4.”
Moses H. Cone Mem'l. Hosp. v. Mercury Constr. Corp.,
If any suit or proceeding be brought in any of the courts of the United States upon any issue referable to arbitration under an agreement in writing for such arbitration, the court in which such suit is pending, upon being satisfied that the issue involved in such suit or proceeding is referable to arbitration under such an agreement, shall on application of one of the parties stay the trial of the action until such arbitration has been had in accordance with the terms of the agreemеnt, providing the applicant for the stay is not in default in proceeding with such arbitration.
9 U.S.C. § 3;
see Midwest Mech. Contractors, Inc. v. Commonwealth Constr. Co.,
A party aggrieved by the alleged failure, neglect, or refusal of another to arbitrate under a written agreement for arbitration may petition any United States district court which, save for such agreement, would have jurisdiction under Title 28, in a civil action or in admiralty of the subject matter of a suit arising out of the controversy between the parties, for an order directing that such arbitration proceed in the manner provided for in such agreement. *390 9 U.S.C. § 4; see Bhatia v. Johnston,818 F.2d 418 , 421 (5th Cir.1987) (noting that, under section 4, a district court must direct the parties to proceed to arbitration of issues covered by an arbitration agreement).
. 9 U.S.C. § 16 provides:
(a) An appeal may be taken from'—
(1) an order—
(A) refusing a stay of any action under section 3 of this title,
*391 (B) denying a petition under section 4 of this title to order arbitration to proceed,
(C) denying an application under section 206 of this title to compel arbitration,
(D) confirming or denying confirmation of an award or partial award, or
(E) modifying, correcting, or vacating an award;
(2) an interlocutory order granting, continuing, or modifying an injunction against an arbitration that is subject to this title; or
(3) a final decision with respect to an arbitration that is subject to this title.
(b) Except as otherwise provided in section 1292(b) of title 28, an appeal may not be taken from an interlocutory order—
(1)granting a stay of any action under section 3 of this title;
(2) directing arbitration to proceed under section 4 of this title;
(3) compelling arbitration under section 206 of this title; or
(4) refusing to enjoin an arbitration that is subject to this title.
. For example, Appellees suggest that the pri- or consolidation of the Federal Actions and State Action placed the entire litigation within the scope of the district court's federal jurisdiction:
Here the Smith Barney Actions were actually consolidated with thе removed State proceeding, and thus the district court had jurisdiction' over the State Proceeding at one time. As a result, when the district court stayed the State Proceeding, it was staying the underlying litigation that was at one time consolidated before the district *392 court. Therefore, the district court's Arbitration Order staying the State Proceeding was not a final decision under the Green Tree line of cases.
By contrast, the district court could have stayed proceedings pursuant to 28 U.S.C. § 2283. Under section 2283, a district court has the authority to stay proceedings in state court where necessary to protect or effectuate its judgment. Here, such a stay may have been needed to proteсt the district court's determination that the Browns’ claims against the Appellees be arbitrated rather than adjudicated in state court. The Browns have not challenged on appeal the district court’s stay of the state court proceeding.
. This situation is similar to that addressed by Judge Dennis in his concurrence in American Heritage:
[T]he stay of the state-court proceedings does not impact our jurisdictional analysis. Although section 3 of the FAA allows courts to stay litigation brought before them, the statute does not authorize federal courts to enjoin ongoing state proceedings. Consequently, the district court did not grant "a stay of any action under section 3 of this title....” More impоrtantly, because the district court reached final decisions with respect to arbitration, the stay component of its orders did not transform them into unappealable "interlocutory order[sj” under section 16(b). "There is nothing interlocutory about an order compelling arbitration that does all that the court has to do.” Accordingly, the stay does not prevent us from exercising appellate jurisdiction.
. "Through Section 16, Congress intended to promote arbitration by 'permitting interlocutory appeals of orders favoring litigation over arbitration and precluding review of interlocutory orders that favor arbitration.' "
Adams
v.
Ga. Gulf Corp.,
[T]he pro-arbitration aims of the statute’s advocates have been achieved in the "embedded” [where the litigation and arbitration proceedings are in the federal court together] proceeding. They have not been, however, in the independent proceeding [where the arbitration proceeding is separate from the underlying litigation]. There, a decision in favor of arbitration can be appealed forthwith, tying the parties down in continued litigation of the issue and swelling the cost — in time, effort, and money — of resolving the dispute, which is wholly at war with the purpose of arbitration and wholly inconsistent with what the sponsors of § 16 wanted to accomplish.
David D. Siegel, Practice Commentary, 9 U.S.C.A. § 16, at 494 (West Supp.1999). Despite these concerns, the courts have viewed the question of reviewability as purely an issue of statutory language and have refused to read congressional intent to overcome this apparent inconsistency.
See Great Earth Companies, Inc. v. Simons,
. Without diversity jurisdiction, Appellees lack an independent basis for the district court's jurisdiction over the Federal Actions as the FAA does not confer federal question jurisdiction.
. This doctrine only applies when there are parallel proceedings pending in federal and state court.
RepublicBank Dallas, Nat. Ass’n v. McIntosh,
. "[A]s a matter of federal law, arbitration agreements and clauses are to be enforced unless they are invalid under principles of state law that govern all contracts.”
Iberia Credit Bureau, Inc. v. Cingular Wireless LLC,
. This circuit does not stаnd alone in approving the use of equitable estoppel against a non-party to an arbitration agreement.
See, e.g., Dominium Austin Partners, L.L.C. v. Emerson,
. The Browns’ claims against Pacific and GE sound in fraud, negligence, and breach of various common law and statutory duties. They allege that, through Holt as their agent, those entities: (1) misrepresented facts and insurance policy provisions to obtain an unjust advantage; (2) failed to disclose that the Browns were purchasing a variable annuity; and (3) misrepresented that the investment plan met the needs of Lonnie and Netty Brown. They also allege that GE and Pacific negligently conferred powers of agency and failed to properly train and supervise Holt.
