The following documents, which previously have been filed by the Registrant with the Commission, are incorporated herein by reference and made a part hereof:

All other reports and other documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) prior to the filing of a post-effective amendment which indicates that all securities offered have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be a part of this Registration Statement from the date of the filing of such reports and documents.

Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Section 490.202 of the Iowa Business Corporation Act (“IBCA”) allows each corporation organized thereunder, such as the Registrant, to include a provision in the articles of incorporation permitting or making obligatory the indemnification of a director for liability to any person for any action taken, or any failure to take any action, as a director, except liability for (i) the receipt of a financial benefit to which the person is not entitled, (ii) an intentional infliction of harm on the corporation or its shareholders, (iii) unlawful distributions to shareholders, or (iv) an intentional violation of criminal law. Section B of Article X of the Second Restatement of the Restated and Amended Articles of Incorporation, as Amended, of the Registrant requires the Registrant to provide indemnification to directors and officers of the Registrant to the fullest extent permitted by the IBCA, as it exists or may be amended, subject to certain limited exceptions including that no such indemnification shall be provided for any proceeding wherein it shall be determined by final judicial decision that such director or officer is liable (i) for a breach of the director’s duty of loyalty to the Registrant or its shareholders, (ii) for acts or omissions not in good faith or which involve any intentional misconduct or knowing violation of the law, (iii) for a transaction from which the director derives an improper personal benefit or (iv) under former Section 496A.44 (comparable to current Section 490.833) of the IBCA related to liability for unlawful distributions.

Section 490.202 of the IBCA also permits corporations to include a provision in the articles of incorporation of each corporation organized thereunder, such as the Registrant, eliminating or limiting, with certain exceptions, the personal liability of a director of the corporation to the corporation or its shareholders for monetary damages for any action taken, or failure to take any action, as a director, except liability for (i) the amount of a financial benefit received by a director to which the director is not entitled, (ii) an intentional infliction of harm on the corporation or its shareholders, (iii) unlawful distributions to shareholders, or (iv) an intentional violation of criminal law.

Section A of Article X of the Second Restatement of the Restated and Amended Articles of Incorporation, as Amended, of the Registrant eliminates the personal liability of each director for monetary damages for breach of fiduciary duty as a director, except for liability (i) for a breach of the director’s duty of loyalty to the Registrant or its shareholders, (ii) for acts or omissions not in good faith or which involve any intentional misconduct or knowing violation of the law, (iii) for a transaction from which the director derives an improper personal benefit or (iv) under former Section 496A.44 (comparable to current Section 490.833) of the IBCA related to liability for unlawful distributions.

Said Section A, however, also contains a provision providing that if the IBCA is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Registrant shall be eliminated or limited to the further extension permitted by the IBCA, as so amended. The Registrant’s “liability shield”, therefore, is as extensive as that now allowed under Section 490.202 of the IBCA.

Section B of Article X further provides that the Registrant may, but is not required to, maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Registrant against any expense, liability or loss whether or not the Registrant would have the power to indemnify such person against such expense, liability or loss under the IBCA. The Registrant carries standard directors’ and officers’ liability coverage for its directors and officers. Subject to certain limitations, the policy reimburses the Registrant for liabilities indemnified under Article X and indemnifies directors and officers against additional liabilities not indemnified under Article X.

The foregoing statements are subject to the detailed provisions of Section 490.202 of the IBCA and Article X of the Second Restatement of the Restated and Amended Articles of Incorporation, as Amended, of the Registrant, as applicable.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

* Filed herewith.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
