ARTICLE 5 INDEMNIFICATION 5.1. Indemnification by the Shareholder. In addition to any other remedies available to Key and WellTech under this Agreement (including, without limitation, those remedies specified in Section 5.5 hereof), or at law or in equity, the Shareholder shall indemnify, defend and hold harmless each of Key and WellTech, and their respective officers, directors, employees, agents and stockholders, against and with respect to any and all claims, costs, damages, losses, expenses, obliga tions, liabilities, recoveries, suits, causes of action and deficiencies, including interest, penalties and reasonable attorneys' fees and expenses (collectively, the "Damages") that such indemnitees shall incur or suffer, which arise, result from or relate to (i) any breach of, or failure by the Shareholder to perform, his respective representations, warranties, covenants or agreements in this Agreement or in any schedule, certificate, exhibit or other instrument furnished or delivered to WellTech or Key by the Shareholder under this Agreement or (ii) Woodward's relationship with any Terminated Employee. 5.2. Indemnification by Key and WellTech. In addition to any other remedies available to the Shareholder under this Agreement, or at law or in equity, WellTech and Key shall jointly and severally indemnify, defend and hold harmless the Shareholder and his employees and agents against and with respect to any and all Damages that such indemnitees shall incur or suffer, which arise, result from or relate to any breach of, or failure by WellTech or Key to perform, any of its representations, warranties, covenants or agreements in this Agreement or in any schedule, certificate, exhibit or other instrument furnished or delivered to Woodward or the Shareholder by or on behalf of Key or WellTech under this Agreement. 5.3. Indemnification Procedure. In the event that any party hereto discovers or otherwise becomes aware of an indemnification claim arising under Section 5.1 or Section 5.2 of this Agreement, such indemnified party shall give written notice to the indemnifying party, specifying such claim, and may thereafter exercise any remedies available to such party under this Agreement; 20 provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of any obligations hereunder, to the extent the indemnifying party is not materially prejudiced thereby. Further, promptly after receipt by an indemnified party hereunder of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Article 5, such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party, give written notice to the latter of the commencement of such action; provided, however, that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of any obligations hereunder, to the extent the indemnifying party is not materially prejudiced thereby. In case any such action is brought against an indemnified party, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after such notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof unless the indemnifying party has failed to assume the defense of such claim and to employ counsel reasonably satisfactory to such indemnified person. An indemnifying party who elects not to assume the defense of a claim shall not be liable for the fees and expenses of more than one counsel in any single jurisdiction for all parties indemnified by such indemnifying party with respect to such claim or with respect to claims separate but similar or related in the same jurisdiction arising out of the same general allegations. Notwithstanding any of the foregoing to the contrary, the indemnified party will be entitled to select its own counsel and assume the defense of any action brought against it if the indemnifying party fails to select counsel reasonably satisfactory to the indemnified party, the expenses of such defense to be paid by the indemnifying party. No indemnifying party shall consent to entry of any judgment or enter into any settlement with respect to a claim without the consent of the indemnified party, which consent shall not be unreasonably withheld, or unless such judgment or settlement includes as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability with respect to such claim. No indemnified party shall consent to entry of any judgment or enter into any settlement of any such action, the defense of which has been assumed by an indemnifying party, without the consent of such indemnifying party, which consent shall not be unreasonably withheld. 5.4. Offset. The parties hereto agree that if WellTech or Key shall incur any Damages for which it is entitled to indemnification by the Shareholder pursuant to the terms of this Agreement, Key shall have the right to offset any payments due or to be due under the terms of this Agreement or any other agreement executed in connection herewith, by the amount of the Damages. Such right of offset shall not be considered an exclusive remedy, it being agreed that Key shall also be entitled to exercise any other remedies available to it at law or in equity, including, without limitation, the indemnification rights set forth in this Article 5. In the event of an offset by Key as a result of any account receivable of Woodward not being collected in breach of the representation of the Shareholder in Section 2.1.6 hereof, upon any such offset, Key shall assign to the Shareholder the account receivable subject to offset, and the Shareholder shall thereafter have the right to take any reasonable action to collect such account receivable. In the event of an offset by Key as a result of 21 any inventory of Woodward being unsalable in the normal course of business in breach of the representations of Woodward and the Shareholder in Section 2.1.6 hereof, upon any such offset, Key shall convey and transfer to the Shareholder title to such inventory subject to offset. 5.5. Self Insurance Agreement. Notwithstanding any provision of this Article 5 or elsewhere herein to the contrary, and notwithstanding the accuracy of the Shareholder's representation contained in Section 2.1.7, the Shareholder shall indemnify, defend and hold harmless each of Key and WellTech, and their respective officers, directors, employees, agents and stockholders against and with respect to any and all Damages arising during the one-year period beginning on the date hereof that such indemnitees shall incur or suffer, which arise or result from or relate to WellTech's assumption of Woodward's obligations under the self-insurance pooling agreement referred to in Schedule 2.1.7 hereto, but only to the extent that such Damages (the "Self Insurance Damages") exceed $25,000 in the aggregate during such one-year period. The Shareholder shall not be liable for any Self Insurance Damages arising on or after September 30, 1997. ARTICLE 6 MISCELLANEOUS 6.1. Survival of Representations, Warranties and Covenants. All representations and warranties made by the parties hereto shall survive for a period of 14 months from the date hereof, notwithstanding any investigation made by or on behalf of any of the parties hereto; provided, however, that the representations and warranties contained in Section 2.1.11 hereof shall survive until the expiration of the applicable statute of limitations associated with the taxes at issue.
