indemnify and hold harmless the Purchaser and upon request of the Purchaser any DYNA Group Company from any Exercise Event claim as well as any costs and expenses incurred in connection with an Exercise Event. The indemnification pursuant to this Section 9.1 shall not apply if the claim exists solely due to the fact that the Company changed its operation compared to the operations as presently conducted. The burden of proof for the fact that the Company did not change its business is with the Purchaser if (i) an alleged Exercise Event claim is based on the facts that the Company changed its operations and (ii) in the event the Sellers 1 through 3 ceased to be managing director of the Company or DYNA GmbH.

9.4 Coverage of Indemnification

The indemnifications of Sections 9.1 and 9.3 shall also cover all Losses, including actual damages incurred by the Exercise Event and / or the satisfaction of the retransfer obligation pursuant to Section 9.3 and, in particular, any consequential damages (Folgeschäden) and any loss of profits (entgangener Gewinn); provided, however, the limitations pursuant to Sections 5.2.1, 5.4 and 5.5 shall apply accordingly.

9.5 Limitations

Any claims of the Purchaser under this Section 9 shall be time-barred (verjähren) on 30 June 2015.

Any payment to be made under this Section 9 by the Sellers shall become payable ten (10) Business Days after the Sellers have received from the Purchaser a notification in writing stating the amount of the Losses.

Any payments by the Sellers to the Purchaser under this Section 9 shall be regarded as a reduction of the Purchase Price. For the sake of clarity, the indemnifications pursuant to this Section 9 shall be satisfied (i) first by transfer of shares or cash, out of the Hold Back from the Sellers to the Purchaser, if possible, and (ii) next, in the event the claims of the Purchaser exceed the value of the Hold Back or the Hold Back has been released, by delivery of any of the Stock Consideration (not currently in the Hold Back) or cash.

Covenants

10.2 Dynamic Materials Covenants

Dynamic Materials will use its best efforts to ensure that the DMC Common Stock held by the Sellers will be registered with Nasdaq or a similar stock exchange where DMC stock is registered for trading by and including 31 December 2008. As soon as reasonably possible, but no later than 30 April 2008, Dynamic Materials shall file with the U.S. Securities and Exchange Commission (“SEC”) a registration statement to permit the Sellers to freely sell all of the shares of DMC Common Stock held by the Sellers following the date such shares are no longer subject to the transfer restrictions of Section 3.2. Dynamic Materials will provide Sellers with a copy of the registration statement and any amendments thereto. Dynamic Materials will use its best efforts and guarantees (by way of an independent guarantee pursuant to Sec. 311 German Civil Code) to Sellers that it will undertake all costs and expenses necessary to register such shares under the Securities Laws pursuant to standard terms and conditions to permit them to be freely tradeable by the Sellers. In the event Dynamic Materials becomes aware of any planned delisting of DMC Common Stock, Dynamic Materials will use its best efforts and guarantees (by way of an independent guarantee pursuant to Sec. 311 German Civil Code) to Sellers, that it will undertake all costs and expenses necessary to register such shares under the Securities Laws pursuant to standard terms and conditions to permit them to be freely tradeable by the Sellers immediately after such earlier date.

Sec. 11.

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.

11.1.2. The Sellers acknowledge and agree that the value to the Purchaser of the transactions contemplated by this Agreement would be substantially and materially diminished if any of the Sellers, directly or indirectly, were to breach any of the provisions of this Section 11.1, and the Sellers have therefore agreed to the provisions of this Section 11.1 as a material inducement to the Purchaser to enter into this Agreement. 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

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).
