MEMORANDUM

Global Client Solutions and Rocky Mountain Bank & Trust (collectively Defendants) appeal from the district court’s denial of their motion to compel arbitration in a purported class action brought by Heather Newton.

1. We review a district court’s decision on the arbitrability of a dispute de novo. PowerAgent Inc. v. Electronic Data Systems Corp., 358 F.3d 1187, 1191-92 (9th Cir.2004). The district court properly decided the arbitrability of this dispute, because (1) the parties did not assign the issue of arbitrability to the arbitrator and (2) the crux of Newton’s complaint is not a challenge to the entire contract’s validity. Bridge Fund Capital v. Fastbucks Franchise, 622 F.3d 996, 1000 (9th Cir.2010); Buckeye Check Cashing, Inc. v. Cardegna, 546 U.S. 440, 444 , 126 S.Ct. 1204 , 163 L.Ed.2d 1038 (2006). Instead, Newton alleges in her complaint that Defendants charged illegal fees, provided negligent services, and made misrepresentations. Further, Buckeye’s “crux of the complaint” rule does not require the party opposing arbitration to have plead such opposition in its pleadings. Bridge Fund, 622 F.3d at 1001 .

2. The Federal Arbitration Act establishes that contractual arbitration agreements must be enforced “save upon such grounds as exist at law or in equity for the revocation of any contract.” 9 U.S.C. § 2 . These grounds include “generally applicable contract defenses,” AT&T Mobility LLC v. Concepcion, — U.S. -, 131 S.Ct. 1740 , 1746, 179 L.Ed.2d 742 (2011) (internal quotation marks omitted), like state law unconscionability, Circuit City Stores, Inc. v. Adams, 279 F.3d 889, 892 (9th Cir.2002), if “agnostic towards arbitration,” Chavarria v. Ralphs Grocery Co., 733 F.3d 916, 927 (9th Cir.2013). In California, a contract clause is unconscionable if both procedurally and substantively unconscionable. Armendariz v. Found. Health Psychcare Servs., Inc., 24 Cal.4th 83 , 99 Cal.Rptr.2d 745 , 6 P.3d 669, 689-90 (2000) (articulating “general principles” of unconscionability). We review a district court’s denial of a motion to compel arbitration de novo, Kilgore v. KeyBank, Nat. Ass’n, 718 F.3d 1052, 1057 (9th Cir.2013) (en banc), and its factual findings for clear error, Nagrampa v. MailCoups, Inc., 469 F.3d 1257, 1267-68 (9th Cir.2006) (en banc).

Whether an arbitration agreement is proeedurally unconscionable depends on ‘“the manner in which the contract was negotiated and the circumstances of the parties at that time.’ ” Ingle v. Circuit City Stores, Inc., 328 F.3d 1165, 1171 (9th Cir.2003) (quoting Kinney v. United, HealthCare Servs., Inc., 70 Cal.App.4th 1322 , 83 Cal.Rptr.2d 348, 352-53 (1999)). Elemental to this inquiry is whether the agreement “involves oppression or surprise.” Id. Defendants concede the arbitration agreement was an adhesion contract. As a result, it is oppressive (and therefore procedurally unconscionable). Flores v. Transamerica HomeFirst, Inc., 93 Cal. App.4th 846 , 113 Cal.Rptr.2d 376, 382 (2001). Surprise is also present, because (1) Newton did not sign the arbitration agreement (it was incorporated by reference); (2) the arbitration agreement was on the reverse side of a one-page document; and the arbitration agreement was in small print. Ingle, 328 F.3d at 1171 . Involving both oppression and surprise, the agreement is proeedurally unconscionable.

Contract provisions are substantively unconscionable if “unfairly one-sided.” Little v. Auto Stiegler, Inc., 29 Cal.4th 1064 , 130 Cal.Rptr.2d 892 , 63 P.3d 979, 984 (2003). Four aspects of this arbitration agreement render it substantively unconscionable. First, the arbitration forum provision requires Newton, who resides in California, to arbitrate in Tulsa, Oklahoma — Global Client Solutions’s headquarters. See Bolter v. Superior Court, 87 Cal.App.4th 900 , 104 Cal.Rptr.2d 888, 894 (2001) (finding substantive unconscionability when California litigants were required to arbitrate in Utah). Second, the arbitration agreement reserves the selection of an arbitrator solely to Defendants. See Sehulster Tunnels/Pre-Con v. Traylor Bros., Inc./Obayashi Corp., 111 Cal.App.4th 1328 , 4 Cal.Rptr.3d 655, 666 (2003) (“A single arbitrator unilaterally selected by a contracting party adverse to the other party is presumed to be biased.”). Third, the arbitration agreement limits damages otherwise available to Newton under statute. See Armendariz, 99 Cal.Rptr.2d 745 , 6 P.3d at 694 (“The unconscionable one-sid-edness of the arbitration agreement is compounded ... by the fact that it does not permit the full recovery of damages for employees, while placing no such restriction on the employer.”). Finally, the arbitration agreement increases Newton’s potential liability for attorney fees as compared to California’s codified fee shifting regime. See Ting v. AT&T, 319 F.3d 1126 , 1151 (9th Cir.2003) (“[Parties that agree to arbitrate statutory claims still are entitled to basic procedural and remedial protections so that they can effectively realize their statutory rights.”). These four provisions demonstrate substantive uncon-scionability.

In making this determination, we harmonize with Concepcion, because our decision is not founded on a policy “unfavorable to arbitration.” Mortensen v. Bresnan Commc’ns, LLC, 722 F.3d 1151, 1160 (9th Cir.2013) (citing Concepcion, 131 S.Ct. at 1748). Instead, our inquiry is based on general California law respecting unconscionable contracts. See Armendariz, 99 Cal.Rptr.2d 745 , 6 P.3d at 689 ; Chavarria, 733 F.3d at 927 .

3. In California, severance is preferred over “voiding the entire agreement.” Armendariz, 99 Cal.Rptr.2d 745 , 6 P.3d at 696 . The United States Supreme Court has an even stronger preference for severance in the context of arbitration agreements. See Concepcion, 131 S.Ct. at 1749 (recognizing “a liberal federal policy favoring arbitration” in the FAA). However, California law does not permit severing illegal provisions of an agreement if its “central purpose ... is tainted with illegality,” Marathon Entm’t, Inc. v. Blasi, 42 Cal.4th 974 , 70 Cal.Rptr.3d 727 , 174 P.3d 741, 754 (2008), and “a district court’s choice not to sever unconscionable portions of an arbitration agreement” is reviewed “for abuse of discretion,” Bridge Fund, 622 F.3d at 1000 .

The district court did not implausibly or illogieally decline to sever the unconscionable parts of this arbitration agreement, Forest Grove Sch. Dist. v. T.A., 638 F.3d 1234, 1238 (9th Cir.2011), despite Congress’s preference for arbitration. The arbitration agreement included four unconscionable provisions. To have severed all of them would have left a mere agreement to arbitrate, therefore requiring extensive reformation of the arbitration agreement. Armendariz, 99 Cal.Rptr.2d 745 , 6 P.3d at 696-97 .

The district court’s judgment is AFFIRMED.

This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3. . "California's procedural unconscionability rules do not disproportionately affect arbitration agreements, for they focus on the parties and the circumstances of the agreement and apply equally to the formation of all contracts.” Chav arria, 733 F.3d at 926 . . That the damages limitation and fee shifting provisions were located outside of the specific arbitration clause does not mean those provisions cannot be considered when determining unconscionability of the arbitration agreement. See Rent-A-Center, West Inc. v. Jack son, 561 U.S. 63 , 73, 130 S.Ct. 2772 , 2780, 177 L.Ed.2d 403 (2010) (noting that provisions outside the specific arbitration clause may be considered in determining whether an arbitration agreement is unconscionable if those provisions "as applied" to the arbitration clause render it unconscionable).
