until the earliest to occur of (i) the Effective Time and (ii) the termination
of the Merger Agreement in accordance with its terms (the “Expiration Time”), at
any meeting (whether annual or special, and at each adjourned or postponed
meeting) of the Company’s shareholders, however called, for the purpose of, or
in connection with any written consent of the Company’s shareholders with
respect to, seeking shareholder approval of the Merger Agreement (a “Shareholder
Meeting”), Shareholder will (x) appear at such meeting or otherwise cause the
Owned Shares to be counted as present thereat for purposes of calculating a
quorum, and respond to each request by the Company for written consent, if any
and (y) vote, or cause to be voted (including by written consent, if

Company (other than pursuant to or as expressly permitted by the Merger
Agreement).

        Section 2.2    Additional Shares. Shareholder hereby agrees, while this
Agreement is in effect, to promptly notify MergerCo of the number of any new

herein, Shareholder agrees, from the date hereof until the Expiration Time, not
to (i) directly or indirectly Transfer any Owned Shares other than any Transfer

to be bound by the terms 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 shall be to their legal

Permitted Transferees as described in subclause (i) above). Any action attempted
to be taken in violation of the preceding sentence will be null and void.
Shareholder further agrees to authorize and request MergerCo and the Company to
notify 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 Section 2.3) and that this Agreement places limits on the
voting of the Owned Shares.

in each case, solely on the matters set forth in, and in the manner contemplated

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

automatically revoked upon termination of this Agreement in accordance with its
terms.

any of the covenants or conditions contained in 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.

this Agreement, any and all remedies expressly conferred upon a party to this

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 seek an injunction or injunctions

        Section 6.16    Submission to Jurisdiction. Each of the parties hereto
irrevocably agrees that any legal action or proceeding with respect to this

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

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

(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

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

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.
