ARTICLE X

INDEMNIFICATION

Subject to the limitations set forth in Section 10.4, each of the Vendors shall indemnify and hold harmless the Purchaser from and against, and shall reimburse the Purchaser for, any Damages which may be sustained, suffered or incurred by them, whether as a result of any Third Party Claim or otherwise, and which arise from or in connection with or are attributable to the breach of any of the representations or warranties or covenants by

Sihitech, any Individual Shareholder or the Vendors contained in this Agreement. Indemnification pursuant to this Section 10.1 shall be the sole remedy of the Purchaser with respect to any breach of the representations and warranties or covenants by Sihitech, any Individual Shareholder or any Vendor contained in this Agreement. Each Vendor shall give prompt written notice to the Purchaser of any Third Party Claims or other facts and circumstances known to them which may entitle the Purchaser to indemnification under this Section 10.1.

10.2 Indemnification by the Purchaser. Subject to the limitations set forth in Section 10.4, the Purchaser shall indemnify and hold harmless each Vendor from and against, and shall reimburse each Vendor for, any Damages which may be sustained, suffered or incurred by such Vendor, whether as a result of Third Party Claims or otherwise, and which arise or result from or in connection with or are attributable to the breach of any of the Purchaser’s representations or warranties or covenants contained in this Agreement. The Purchaser shall give each Vendor prompt written notice of any Third Party Claims or other facts and circumstances known to it which may entitle them to indemnification under this Section 10.2.

10.3 Notice, Etc. A Party required to make an indemnification payment pursuant to this Agreement (Indemnifying Party) shall have no liability with respect to Third Party Claims or otherwise with respect to any covenant, representation, warranty, agreement, undertaking or obligation under this Agreement unless the Party entitled to receive such indemnification payment (Indemnified Party) gives notice to the Indemnifying Party specifying (i) the covenant, representation or warranty, agreement, undertaking or obligation contained herein which it asserts has been breached, (ii) in reasonable detail, the nature and dollar amount of any Claim the Indemnified Party may have against the Indemnifying Party by reason thereof under this Agreement, and (iii) whether or not the Claim is a Third Party Claim. With respect to Third Party Claims, an Indemnified Party (i) shall give the Indemnifying Party prompt notice of any Third Party Claim, (ii) prior to taking any action with respect to such Third Party Claim, shall consult with the Indemnifying Party as to the procedure to be followed in defending, settling, or compromising the Third Party Claim, (iii) shall not consent to any settlement or compromise of the Third Party Claim without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed), and (iv) shall permit the Indemnifying Party, if it so elects, to assume the exclusive defense of such Third Party Claim (including, except as provided in the penultimate sentence of this Section, the compromise or settlement thereof) at its own cost and expense. If the Indemnifying Party shall elect to assume the exclusive defense of any Third Party Claim pursuant to this Agreement, it shall notify the Indemnified Party in writing of such election, and the Indemnifying Party shall not be liable hereunder for any fees or expenses of the Indemnified Party’s counsel relating to such Third Party Claim after the date of delivery to the Indemnified Party of such notice of election. The Indemnifying Party will not compromise or settle any such Third Party Claim without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed) if the relief provided is other than monetary damages or such relief would have a material adverse effect on the Indemnified Party. Notwithstanding the foregoing, if the Indemnifying Party elects to assume the defense with respect to any Third Party Claim,

the Indemnifying Party shall have the right to compromise or settle for solely monetary damages such Third Party Claim, provided such settlement will not result in or have a Material Adverse Effect on the Indemnified Party. Notwithstanding the foregoing, the Party which defends any Third Party Claim shall, to the extent required by any insurance policies of the Indemnified Party, share or give control thereof to any insurer with respect to such Claim.

10.4 Limitations.

(a) No Vendor shall be required to indemnify the Purchaser under Section 10.1 unless the aggregate of all amounts for which indemnity would otherwise be due against them exceeds US$10,000. Claims may be asserted once the damages exceed US$10,000, and in no event the indemnification amount shall exceed the Purchase Price.

(b) The Purchaser shall not be required to indemnify any Vendor under Section 10.2 unless the aggregate of all amounts for which indemnity would otherwise be due against the Purchaser exceeds $10,000. Claims may be asserted once the damages exceed US$10,000, and in no event the indemnification amount shall exceed the Purchase Price.

(d) In no event shall a claim for indemnification be made after the second anniversary of the Closing Date.

10.5 Adjustment to Purchase Price; Setoff.

(a) Purchase Price. Any indemnification payments made pursuant to Sections 10.1 and 10.2 shall be deemed to be an adjustment to the Purchase Price. To the extent that any Vendor is obligated to indemnify the Purchaser under the provisions of the Article X for Damages reduced to a monetary amount, the Purchaser shall have the right to adjust any amount due and owing or to be due and owing under any agreement with the Vendors, whether under this Agreement or any other agreement between the Vendors and any of the Purchaser’s affiliates, subsidiaries or controlled persons or entities. To the extent that the Purchaser is obligated to indemnify Sihitech or any Vendor after Closing under the provisions of this Article X for Damages reduced to a monetary amount, Sihitech or any Vendor after Closing shall have the right to decrease any amount due and owing or to be due and owing under any agreement with the Purchaser, whether under this Agreement or any other agreement between the Sihitech or the Vendors and any of the Purchaser’s affiliates, subsidiaries or controlled persons or entities.

(b) Holdback Amount. Notwithstanding the foregoing, the Purchaser may apply all or a portion of the Holdback Amount to satisfy any Claim for indemnification pursuant to this Article X. The Purchaser will hold the Holdback Amount until final resolution of the Claim or dispute. The Holdback Amount is security for the indemnification obligations of the Vendors and is not a limitation on the Damages recoverable or liquidated damages and such security does not limit any other right of set off or recovery under this Agreement or at law, whether pursuant to this Agreement or any other agreement of the Vendors.
