Subject to Section 5.2, in the event of any breach or non fulfillment by the Sellers’ guarantees or covenants contained in this Agreement, the Sellers shall be liable as partial debtors (Teilschuldner) for putting the Purchaser, or at the election of the Purchaser, the DYNA Group

37

5.5                               Mitigation

Sec. 254 of the German Civil Code shall remain unaffected, i.e., the Purchaser is in particular obliged to prevent the occurrence of any damages and to limit the scope of any damages incurred.  If any of the DYNA Group Companies has a monetary advantage (geldwerten Vorteil) in connection with a breach of a Guarantee this shall mitigate the remedies of the Purchaser under this Agreement or, if this mitigation is impossible, the respective assets (reflecting the monetary advantage) shall be provided to the Sellers.

5.6                               Limitation Periods and Notice of Claim

All of the guaranties of the Sellers in this Agreement shall survive the Closing hereunder (even if the Purchaser knew or had reason to know of any misrepresentation or breach of guaranties at the time of Closing).

Sec. 11.          

NON-COMPETITION CLAUSE

11.1                        Non-Compete Covenant

11.1.1.                     For a period of five (5) years after the Closing Date, the respective Sellers and Mr. Mertens shall not, either directly or indirectly, engage in the Geographical Markets in any competition to the Business as presently conducted (herein referred to as “Competitive Activities”), or directly or indirectly manage, assist or acquire any interest (equity or votes) in any companies conducting any Competitive Activities (except the acquisition of shares of the DMC Common Stock as outlined above and except any activity the Sellers or any of them will conduct for any of the DYNA Group Company in accord with the Purchaser). “Geographical Markets” herein shall mean the markets in which DYNA Group Companies are currently active in the Business or have been themselves directly (including via direct participations in consortiums or other co-operations) active in the Business in the last five (5) years before the Closing Date.  The obligations of this Section 11.1.1 shall terminate as to Mr. Mertens (i) in respect to certain regions, upon the termination of an agreement disclosed in Annex 11.1.1-1 relating to such region, in which ANKO Industry Service GmbH was obliged to provide services under the respective agreement terminated, and (ii) in respect to certain clients, upon the full or partly termination of the provision agreement disclosed

48

in Annex 11.1.1-2 relating to such clients, for which the payment of provisions according that provision agreement is terminated.

The Sellers specifically acknowledge and agree that the provisions of this Section 11.1 are commercially reasonable restraints in accordance with common market practice, which in light of the investment, effort and risk to acquire hereunder and thereafter operate the business of the DYNA Group Companies are reasonably necessary to protect the value of the DYNA Group Companies and their Business. The Sellers acknowledge and agree that the Purchaser could be irreparably damaged by a breach of this Section 11.1 and would not be adequately compensated by monetary damages for any such breach and thus shall also be entitled to injunctive relief.

11.2                        Non-Solicitation Covenant

11.2.1.                     For a period of five (5) years after the Closing Date, the respective Sellers shall not solicit or entice away from any of the DYNA Group Companies any person who presently or during such period is employed by any of the DYNA Group Companies.

11.2.2.                     For a period of five (5) years after the Closing Date, the respective Sellers shall not solicit any clients or customers of any of the DYNA Group Companies or endeavour to entice away from any DYNA Group Companies any person who is or has been a client or customer of any of the DYNA Group Companies.

11.3                        Minority Participation in Listed Companies

Any direct or indirect participations in listed companies shall be excluded from the non-compete provisions under Section 11.1, as long as the percentage of the participation of the Sellers and any current or future companies of the Sellers’ does not exceed five percent (5%) of the respective listed companies and the participation is for investment purposes only (i.e., the mere holding of shares).

11.4                        Liquidated Damages

If the Sellers do not comply with any of the provisions of this Section 11.1 through 11.3, such

49

Seller shall be liable to the Purchaser for payment of liquidated damages (pauschalierter Schadensersatz) in the amount of EUR 2,000,000 (Euro two million) for each case of non-compliance. The Purchaser is entitled to claim actual damages (Schadensersatzansprüche) that exceed the Liquidated Damages with respect to such non-compliance.  The Sellers are entitled to prove, that the actual damages of the Purchaser in respect to such non-compliance are less than EUR 2,000,000 (Euro two million).
