(xviii) committed to do any of the foregoing.
 
5.10 Insurance. The insurance policies taken out by STF are sufficient for
compliance by STF with all applicable Legal Requirements and all material
Contracts. None of the insurance carriers has indicated to STF an intention to
cancel any such policy or to materially increase any insurance premiums
(including, without limitation, workers’ compensation premiums), or that any
insurance required to be listed on Schedule 5.10 will not be available in the
future on substantially the same terms as currently in effect. STF has no claim
pending or anticipated against any of its insurance carriers under any of such
policies and, to the knowledge of STF, there has been no actual or alleged
occurrence of any kind which could reasonably be expected to give rise to any
such claim. During the prior three years, all notices required to have been
given by STF to any insurance STF have been timely and duly given, and no
insurance STF has asserted that any claim is not covered by the applicable
policy relating to such claim.

5.11, STF (x) has not received or entered into any citations, complaints,
consent orders, compliance schedules, or other similar enforcement orders or
received any written notice from any Governmental Authority or any other written

Legal Requirements, except for failures to so comply that would not have a
Material Adverse Effect, and (y) is not in default under, and no condition
exists (whether covered by insurance or not) that with or without notice or
lapse of time or both would constitute a default under, or breach or violation
of, any Legal Requirement or Permit applicable to STF, which default would have
a Material Adverse Effect. Without limiting the generality of the foregoing, STF
has not received notice of and there is no basis for, any claim, action, suit,
investigation or proceeding that might result in a finding that STF is not or
has not been in compliance with Legal Requirements relating to (a) the

effect (whether covered by insurance or not) on the business, operations,
prospects, Properties or financial condition of STF and/or AEP and there is no
basis for any such claim, action, suit, investigation or proceeding. Schedule

STF is not, and to its knowledge the other Party is not in default or breach
under any such Lease. No event has occurred which, with the passage of time or
the giving of notice or both, would cause a material breach of or default under
any of such Leases.

dividing (A) the amount of Damages, by (B) the Per Share Value (as defined
below). The “Per Share Value” shall be, (x) for STF Conversion Shares the per
share closing price of the STF Conversion Shares as at the date that the
liability of the Company Stockholders and the applicable amount of Damages shall
have been determined, and (y) for Exchange Shares the per share closing price of

9.3  Indemnified Party and Indemnifying Party. For purposes of this Section 9.3,
a Party making a claim for indemnity under Section 9.1 or Section 9.2 is
hereinafter referred to as an “Indemnified Party” and the Party against whom
such claim is asserted is hereinafter referred to as the “Indemnifying Party.”
All claims by any Indemnified Party shall be asserted and resolved in accordance
with the following provisions. If any claim or demand for which an Indemnifying
Party would be liable to an Indemnified Party is asserted against or sought to
be collected from such Indemnified Party by a third party, said Indemnified
Party shall with reasonable promptness notify in writing the Indemnifying Party
of such claim or demand stating with reasonable specificity the circumstances of
the Indemnified Party’s claim for indemnification; provided, however, that any
failure to give such notice will not waive any rights of the Indemnified Party
except to the extent the rights of the Indemnifying Party are actually
prejudiced or to the extent that any applicable period set forth in Section 9.1
and Section 9.2(b) has expired without such notice being given. After receipt by
the Indemnifying Party of such notice, then upon reasonable notice from the
Indemnifying Party to the Indemnified Party, or upon the request of the
Indemnified Party, the Indemnifying Party shall defend, manage and conduct any
proceedings, negotiations or communications involving any claimant whose claim
is the subject of the Indemnified Party’s notice to the Indemnifying Party as
set forth above, and shall take all actions necessary, including but not limited
to the posting of such bond or other security as may be required by any
Governmental Authority, so as to enable the claim to be defended against or
resolved without expense or other action by the Indemnified Party. Upon request
of the Indemnifying Party, the Indemnified Party shall, to the extent it may
legally do so and to the extent that it is compensated in advance by the
Indemnifying Party for any costs and expenses thereby incurred,
 
(i) take such action as the Indemnifying Party may reasonably request in
connection with such action,
 
(ii) allow the Indemnifying Party to dispute such action in the name of the
Indemnified Party and to conduct a defense to such action on behalf of the
Indemnified Party, and
 
(iii) render to the Indemnifying Party all such assistance as the Indemnifying
Party may reasonably request in connection with such dispute and defense.

the Management Holding Company accedes to this Agreement and assumes all
obligations of its shareholders hereunder, and (iii) the Management Stockholders
(or, if the Management Holding Company owned by the Company Stockholders, the
Company Stockholders) guarantee all obligations and liabilities of the
Management Holding Company under this Agreement.
 
9.5  Resolution of Disputes.
 
(a)  All disputes, claims or controversies arising out of or relating to this
Agreement, or any agreement executed and delivered pursuant hereto, or the
negotiation, breach, validity or performance hereof, or the transactions
contemplated hereby which cannot be resolved by good faith negotiations, shall
be exclusively submitted to final and binding arbitration in London England
before a panel of three arbitrators appointed by the International Chamber of
Commerce; provided, that if any Party has no adequate remedy at law he or it may
seek emergency injunctive relief or specific performance before any court of
competent jurisdiction in Germany or the United States. The decision and award
of the arbitrators shall be enforceable in any court of competent jurisdiction
in the United States and Germany.
 
(b)  The Parties covenant and agree that the arbitration shall commence within
ninety (90) days of the date on which a written demand for arbitration is filed
by any Party hereto. In connection with the arbitration proceeding, the
arbitrators shall have the power to order the production of documents by each
Party and any third-Party witnesses. In connection with any arbitration, each
Party shall provide to the other, no later than seven (7) business days before
the date of the arbitration, the identity of all persons that may testify at the
arbitration and a copy of all documents that may be introduced at the
arbitration or considered or used by a Party’s witness or expert. The
arbitrators’ decision and award shall be made and delivered within six (6)
months of the selection of the arbitrators. The arbitrators’ decision shall set
forth a reasoned basis for any award of damages or finding of liability. The
arbitrators shall not have power to award damages in excess of actual
compensatory damages and shall not multiply actual damages or award punitive
damages or any other damages that are specifically excluded under this
Agreement, and each Party hereby irrevocably waives any claim to such damages.
 
(c)  The Parties covenant and agree that they will participate in the
arbitration in good faith and that they will, except as provided below, (A) bear
their own attorneys’ fees, costs and expenses in connection with the
arbitration, and (B) share equally in the fees and expenses charged by the
arbitrators. The arbitrators may in their discretion assess costs and expenses
(including the reasonable legal fees and expenses of the prevailing Party)
against any Party to the proceeding. Any Party unsuccessfully refusing to comply
with an order of the arbitrators shall be liable for costs and expenses,
including attorneys’ fees, incurred by the other Party in enforcing the award.
This Section 9.4. applies equally to requests for temporary, preliminary or
permanent injunctive relief, except that in the case of temporary or preliminary
injunctive relief any Party may proceed in court without prior arbitration for
the purpose of avoiding immediate and irreparable harm or to enforce its rights
under any non-competition covenants.
