|   |  | This Agreement shall terminate as to ACF or Molan when neither it nor any of its Affiliates (as that term is defined in the Partnership Agreement) is a limited partner in the Company. Following termination of this Agreement as to ACF or Molan, such
company shall have no further rights or obligations hereunder, other than rights or obligations that arose prior to the date of termination.                                                                                                                                                                                                                                                                                                                                        
|3. |  | In the event that SDI USA violates one of its aforementioned legal obligations, the limited partners Klaus-Jürgen Dittrich and Frank Dittrich are entitled to the same claims that would arise from the Partnership Agreement if SDI Germany violated
its obligations under the Partnership Agreement.                                                                                                                                                                                                                                                                                                                                                                                                                                       
|5. |  | In the event that ACF and / or Molan violate one of their aforementioned legal obligations, the limited partner SDI Germany is entitled to assert the same claims it would have if Klaus-Jürgen Dittrich and Frank Dittrich violated their
obligations arising from the Partnership Agreement.                                                                                                                                                                                                                                                                                                                                                                                                                                               
|6. |  | It is understood and agreed that the penalty imposed by Section 16(4) of the Partnership Agreement shall be imposed only once with respect to each violation. Such penalty shall not be imposed once against the limited partner pursuant to the
Partnership Agreement and a second time against its affiliate pursuant to this Agreement.                                                                                                                                                                                                                                                                                                                                                                                                   
|7. |  | § 17 of the Partnership Agreement shall be applied accordingly.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
|8. |  | SDI USA and the Dittrich Partners intend to consider and discuss from time to time opportunities for further cooperation between themselves and/or their affiliates with respect to business activities outside the Territory (as defined in the
Partnership Agreement), especially in Asia. These opportunities might involve expansion of the Territory to include countries currently outside the Territory (other than in North America), the establishment of a joint manufacturing plant in Asia or
elsewhere, opportunities for coordinated marketing, sales, distribution or fulfillment of customer orders, or any other opportunities to coordinate or combine the commercial capabilities of the parties for their mutual benefit.
