The foregoing obligations to indemnify NETsilicon will be determined without regard to any right to indemnification or reimbursement to which any Person may have in his or her capacity as an officer, director, employee, agent or any other capacity of Dimatech, and no Seller will be entitled to any indemnification or reimbursement from Dimatech or NETsilicon for amounts paid hereunder. There will be no right of contribution or subrogation from NETsilicon or Dimatech for indemnification payments made by or for the account of any Seller. 8.02. Third Party Claims. With respect to any claims or demands by third parties as to which NETsilicon may seek indemnification hereunder, whenever NETsilicon will have received a written notice that such a claim or demand has been asserted or threatened, NETsilicon will promptly notify the Seller of such claim or demand and of the facts within NETsilicon's 16 21 knowledge that relate thereto within a reasonable time after receiving such written notice. Seller will then have the right to defend, contest, negotiate or settle any such claim or demand through counsel of their or his own selection, reasonably satisfactory to NETsilicon, and solely at Seller's own cost and expense. Notwithstanding the preceding sentence, Seller will not settle, compromise, or offer to settle or compromise any such claim or demand without the prior written consent of NETsilicon, which consent will not be unreasonably withheld. Without limiting NETsilicon's rights to object for other reasons, NETsilicon may object to a settlement or compromise which includes any provision which in its reasonable judgment may have an adverse impact on or establish an adverse precedent for NETsilicon or any of its subsidiaries. If Seller gives notice to NETsilicon within twenty (20) calendar days after NETsilicon has notified Seller that any such claim or demand has been made in writing, that the Seller elect to have NETsilicon defend, contest, negotiate, or settle any such claim or demand, then NETsilicon will have the right to contest and/or settle any such claim or demand and seek indemnification pursuant to this Article VIII as to any Indemnifiable Amounts; provided, however, that NETsilicon will not settle, compromise, or offer to settle or compromise any such claim or demand without the prior written consent (which may include a general or limited consent) of the Seller, which consent will not be unreasonably withheld. If the Seller fails to give written notice to NETsilicon of Seller's intention to contest or settle any such claim or demand within twenty (20) calendar days after NETsilicon has notified Seller that any such claim or demand has been made in writing, or if any such notice is given but any such claim or demand is not contested by Seller within a reasonable time thereafter, NETsilicon will have the right to contest and/or settle any such claim or demand in its sole discretion and seek indemnification pursuant to this Article XI as to any Indemnifiable Amounts. 8.03. Tax Contests. NETsilicon shall have the right to conduct any Tax audit or other Tax contest relating to Dimatech. NETsilicon will conduct any such Tax audit or other Tax contest in good faith. 8.04. Limitations. Notwithstanding any other provision in this Article VIII, NETsilicon will be entitled to indemnification only to the extent that the aggregate Indemnifiable Amounts (which shall be determined for all purposes of this Article VIII disregarding any qualification in any representation or warranty as to "materially" or "material") exceed $25,000 (the "Threshold Amount"). 8.05. Time Limit. The representations, warranties, covenants and agreements of Dimatech and the Seller set forth in this Agreement will survive the Closing and the consummation of the transactions contemplated by this Agreement, but any claims with respect thereto may be made only on or before the twelve (12) month anniversary of the date of this Agreement; provided, however, that claims relating to Tax matters may be made only on or before the expiration of the applicable Tax statute of limitations (including extensions thereof). 8.06. Post-Closing Dimatech Operations. Without limiting the foregoing provisions of this Article VIII, NetSilicon hereby agrees to defend, indemnify and hold Seller harmless from and against, to reimburse Seller with respect to, and to assume the defense of, any and all losses, damages, liabilities, claims, judgments, settlements, fines, costs and expenses (including reasonable attorneys' fees) of every nature whatsoever incurred by Seller arising out of the post- 17 22 closing operations of Dimatech to the fullest extent permitted by the Massachusetts Business Corporation Law and the Articles of Organization and By-laws of NetSilicon.
