See id. Observing that, given the optional nature of the arbitration provision, the provision did not "take effect" until "one side . . . [made] an arbitration demand," the court held that in the absence of such a demand, "there is no basis to compel the parties to seek arbitration." Id.; see also Wachovia Bank, N.A. v. Bluffwalk Ctr. L.P., No. 08 Civ. 212, 2008 WL 2787399, at *2 (E.D. Va. July 15, 2008) (applying Marcus to deny as "premature" a motion to stay pending arbitration when the party seeking the stay had not yet exercised its option to arbitrate via written notice). Here, AMEX has not suggested that it ever sent a claim notice or selected an arbitrator, satisfying the arbitration clause's terms.
