purposes of this Agreement all other voting           securities into which Shares may be
reclassified, sub-divided, consolidated or           converted and any rights and

and unconditionally agrees that from and after the date hereof and until the earliest to

accordance with its terms (the “Expiration Time”), at any meeting

hereof.  

        Section
2.3    Restrictions on Transfer, Etc. Except as provided for
herein, Shareholder agrees, from the date hereof until the Expiration Time, not to (i)

hereof (or an agreement that is substantively identical to this Agreement) and notice of
such Transfer, including the name and address of the Permitted Transferee, is delivered
to MergerCo pursuant to Section 6.1 hereof; provided that Transfers to minor children

attempted to be taken in violation of the preceding sentence will be null and void.

the Company’s transfer agent that there is a stop transfer order with respect to all
of the Owned Shares (other than in respect of Transfers expressly permitted by this

in the manner contemplated by, Section 2.1. The proxy granted by Shareholder pursuant to
this Section 2.4 is, subject to the last sentence of this Section 2.4, irrevocable and is
coupled with an interest, in accordance with Section 490.722(4) of the IBCA, and is
granted in order to secure Shareholder’s performance under this Agreement. If
Shareholder fails for any reason to be counted as present, consent or vote the Owned
Shares in accordance with the requirements of Section 2.1 above (or anticipatorily
breaches such section), then MergerCo shall have the right to cause to be present,

construed in accordance with, the Laws of the State of Iowa, without giving effect to any
applicable principles of conflict of laws that would cause the Laws of another State to
otherwise govern this Agreement.

severable and the invalidity or unenforceability of any provision will not affect the
validity or enforceability of the other provisions of this Agreement. If any provision of

interest or obligation hereunder may be assigned by any party hereto, in whole or part

and be binding upon the parties hereto and their respective successors and permitted

this Agreement. Any agreement on the part of a party to any extension or waiver will be
valid only if set forth in an instrument in writing signed by such party. The failure of
any party to assert any of its rights under this Agreement or otherwise will not
constitute a waiver of such rights.  

        Section

this Agreement, any and all remedies expressly conferred upon a party to this Agreement
will be cumulative with, and not exclusive of, any other remedy contained in this

remedy will not preclude the exercise by it of any other remedy.  

        Section

may be executed in any number of counterparts, all of which are one and the same
agreement. This Agreement may be executed by facsimile signature by any party and such

signature being thereafter required.  

        Section
6.15    Specific Performance. The parties to this Agreement
agree that irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the parties to this Agreement will be entitled to

specifically the terms and provisions of this Agreement in any court of the United States

        Section
6.16    Submission to Jurisdiction. Each of the parties hereto
irrevocably agrees that any legal action or proceeding with respect to this Agreement and
the rights and obligations arising hereunder, or for recognition and enforcement of any
judgment in respect of this Agreement and the rights and obligations arising hereunder
brought by the other party hereto or its successors or assigns shall be brought and
determined exclusively in the District Court of Iowa, Scott County, or in the event (but
only in the event) that such court does not have subject matter jurisdiction over such
action or proceeding, in the United States District Court for the Southern District of
Iowa. Each of the parties hereto agrees that mailing of process or other papers in
connection with any such action or proceeding in the manner provided in Section 6.1 or in
such other manner as may be permitted by applicable Laws, will be valid and sufficient
service thereof. Each of the parties hereto hereby irrevocably submits with regard to any
such action or proceeding for itself and in respect of its property, generally and
unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it
will not bring any action relating to this Agreement or any of the transactions
contemplated by this Agreement in any court or tribunal other than the aforesaid courts.
Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of
motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect
to this Agreement and the rights and obligations arising hereunder, or for recognition
and enforcement of any judgment in respect of this Agreement and the rights and
obligations arising hereunder (i) any claim that it is not personally subject to the
jurisdiction of the above named courts for any reason other than the failure to serve
process in accordance with this Section 6.16, (ii) any claim that it or its property is
exempt or immune from jurisdiction of any such court or from any legal process commenced
in such courts (whether through service of notice, attachment prior to judgment,
attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii)
to the fullest extent permitted by the applicable Law, any claim that (x) the suit,
action or proceeding in such court is brought in an inconvenient forum, (y) the venue of
such suit, action or proceeding is improper or (z) this Agreement, or the subject matter
hereof, may not be enforced in or by such courts.  

        Section
6.17    Waiver of Jury Trial. Each party acknowledges and
agrees that any controversy which may arise under this Agreement is likely to involve
complicated and difficult issues and, therefore, each such party irrevocably and
unconditionally waives any right it may have to a trial by jury in respect of any Legal
Action arising out of or relating to this Agreement or the transactions contemplated by
this Agreement. Each party to this Agreement certifies and acknowledges that (i) no
Representative of any other party has represented, expressly or otherwise, that such
other party would not seek to enforce the foregoing waiver in the event of a Legal
Action, (ii) such party has considered the implications of this waiver, (iii) such party
makes this waiver voluntarily and (iv) such party has been induced to enter into this
Agreement by, among other things, the mutual waivers and certifications in this Section
6.17.  

        Section
6.18    Action in Shareholder Capacity Only. Notwithstanding anything
to the contrary in this Agreement, the parties acknowledge and agree that this Agreement
is entered into by Shareholder solely in his capacity as the Beneficial Owner of the
Owned Shares and nothing in this Agreement shall in any way restrict, limit or otherwise
affect any action taken or to be taken (or failure to act) by Shareholder in his capacity
as a director, officer, employee or other agent of the Company or any of its Subsidiaries
(but not in his capacity as a shareholder of the Company) and the taking of any actions
(or failure to act) in his capacity as a director, officer, employee or other agent of
the Company or any of its Subsidiaries will not be deemed to constitute a breach of this
Agreement, regardless of the circumstances related thereto.
