     WHEREAS, Husker Ag was formed for the purpose of constructing and operating
an ethanol plant near Plainview, in Pierce County, Nebraska;

     WHEREAS, Husker Ag is, or will be, conducting a public offering of its
membership units and pursuant to the terms and conditions of its prospectus,
Husker Ag has committed to escrow the proceeds of the membership units sold to
investors;

     WHEREAS, Husker Ag wishes to establish an escrow account to hold the
proceeds of subscriptions for the membership units for a minimum of 13,000
membership units and a maximum of 15,000 membership units, until written
instructions from Husker Ag have been received;

     WHEREAS, Midwest Bank N.A. d/b/a Plainview National Bank is willing to hold
the escrow account and serve as Escrow Agent, in accordance with the terms and
conditions provided in this Escrow Agreement.

be entitled to withdraw funds from the Escrow Account as provided herein. Husker

or judgments or creditors' claims against Husker Ag unless and until released to
Husker Ag as hereinafter provided. The pro rata amount of interest to be
