To expedite your review, we are also sending you copies of the Registration Statement marked to show changes from the Amendment No. 1 to Form S-3 filing on July 6, 2010. For ease of reference, we reproduce below the comments and include under each comment the Company’s response.

General
Staff Comment:	1. We note your response to comment one of our letter dated June 25, 2010. We are unable to concur with your belief that the proposed transaction represents a valid secondary offering under Rule 415(a)(1)(i). Please revise the registration statement to identify the selling shareholders as underwriters.

Exhibit 5.1 - Opinion of Husch Blackwell Sanders LLP
Staff Comment:	2. We note that in response to our prior comment 7 you have substituted the phrase “Iowa Business Corporation Act” with “applicable Iowa Law.” Please understand that counsel must opine on the corporate laws of the jurisdiction of incorporation of the registrant. Please have counsel revise the opinion as appropriate.
Company Response:	The legal opinion of Husch Blackwell Sanders LLP has been revised as requested, which is in the form in which the opinion was filed in the original filing of this Registration Statement. Husch Blackwell Sanders LLP hereby confirms that the reference to the Iowa Business Corporation Act includes the statutory provisions and also all applicable provisions of the Iowa Constitution and the reported judicial cases interpreting those laws currently in effect.

Our request for acceleration will include the requested acknowledgements. If you have any questions or comments concerning the matters discussed above, please call me at (402) 315-1629.
