(k) "Snyder Liabilities" shall mean all Liabilities known or unknown, absolute, accrued, contingent or otherwise, arising out of or associated with the affairs or operations of Snyder and any of its subsidiaries and which are not Patina Liabilities. -2- 2. Indemnification. (a) Patina shall defend, indemnify and hold harmless the Snyder Indemnified Parties against any and all Patina Liabilities, whether or not the result of the sole or partial negligence or otherwise culpable conduct or fault of one or more of the Snyder Indemnified Parties. (b) Snyder shall defend, indemnify and hold harmless the Patina Indemnified Parties against any and all Snyder Liabilities, whether or not the result of the sole or partial negligence or otherwise culpable conduct or fault of one or more of the Patina Indemnified Parties. 3. Indemnification Procedure. Each person to be indemnified pursuant to this Agreement (an "Indemnified Party") agrees to give prompt notice to the indemnifying party of the assertion of any claim, or the commencement of any suit, action or proceeding, brought against or sought to be collected from such Indemnified Party (each a "Third Party Claim"), in respect of which indemnity may be sought by such Indemnified Party under this Agreement; provided that the omission so to promptly notify the indemnifying party with respect to a Third Party Claim brought against or sought to be collected from such Indemnified Party will not relieve the indemnifying party from any Liability that it may have to such Indemnified Party under this Agreement except to the extent that such failure has materially prejudiced such indemnifying party with respect to the defense of such Third Party Claim. If any Indemnified Party shall seek indemnity under this Agreement with respect to a Third Party Claim brought against or sought to be collected from such Indemnified Party, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, to assume and direct the defense and settlement thereof with counsel satisfactory to such Indemnified Party. After notice from the indemnifying party to an Indemnified Party of its election to assume and direct the defense and settlement of a Third Party Claim brought against or sought to be collected from such Indemnified Party that such indemnifying party is entitled to assume and direct under the terms hereof, the indemnifying party shall not be liable to such Indemnified Party under this Agreement for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation, unless the Indemnifying Party and the Indemnified Party are both named parties to any such action, claim or demand and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest between them. Notwithstanding the foregoing provisions of this Section 3, the indemnifying party shall not (A) without the prior written consent of an Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which such Indemnified Party is, or with reasonable foreseeability, could have been a party and indemnity could have been sought hereunder by such Indemnified Party for a Third Party Claim brought against or sought to be collected from such Indemnified Party, unless such settlement includes an unconditional release, in form and substance satisfactory to the Indemnified Party, of such Indemnified Party from all Liability arising out of such proceeding (provided that, whether or not such a release is required to be obtained, the indemnifying party shall remain liable to such Indemnified Party in accordance with this Agreement in the event that a Third Party Claim is subsequently brought against or sought to be collected from such Indemnified Party) or (B) be liable for any settlement of any Third Party Claim brought against or sought to be -3- collected from an Indemnified Party effected without such indemnifying party's written consent (which shall not be unreasonably withheld), but if settled with such indemnifying party's written con sent, or if there is a final judgment for the plaintiff in any such Third Party Claim, such indemnifying party agrees (to the extent stated above) to indemnify the Indemnified Party from and against any loss, liability, claim, damage or expense by reason or such settlement or judgment. The indemnification required by this Agreement shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or loss, liability, claim, damage or expense is incurred. 4. Insurance. (a) Notwithstanding any provision to the contrary herein, an indemnifying party hereunder shall have no obligation for a liability or any part thereof sought to be indemnified by an Indemnified Party pursuant to this Agreement to the extent that the Indemnified Party has received payment from an insurer on account of such liability, which payment has not been offset through a matching deductible or premium adjustments made on account of such payment. (b) To the extent that an Indemnified Party may have insurance for a liability or any part thereof sought to be indemnified under this Agreement, until an insurer makes payment on account thereof, the parties shall proceed with indemnification under this Agreement as if the Indemnified Party is not covered by such insurance. An indemnifying party which has paid all or any part of an indemnification claim shall then be reimbursed by the Indemnified Party from insurance payment later received, if any, which payment has not been offset through a matching deductible or premium adjustments made on account of such payment. 5. Assignment. Except by operation of law or in connection with the sale of all or substantially all the assets of a party hereto, this Agreement shall not be assignable, in whole or in part, directly or indirectly, by any party hereto without the written consent of the other party; and any attempt to assign any rights or obligations arising under this Agreement without such consent shall be void; provided, however, that the provisions of this Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and permitted assigns. 6. Further Assurances. Subject to the provisions hereof, the parties hereto shall make, execute, acknowledge and deliver such other instruments and documents, and take all such other actions, as may be reasonably required in order to effectuate the purposes of this Agreement and to consummate the transactions contemplated hereby. Subject to the provisions hereof, each of the parties shall, in connection with entering into this Agreement, performing its obligations hereunder and taking any and all actions relating hereto, comply with all applicable laws, regulations, orders and decrees, obtain all required -4- consents and approvals and make all required filings with any governmental agency, other regulatory or administrative agency, commission or similar authority and promptly provide the other parties with all such information as they may reasonably request in order to be able to comply with the provisions of this sentence. 7. Parties in Interest. Except as herein otherwise specifically provided, nothing in this Agreement expressed or implied is intended to confer any right or benefit upon any person, firm or corporation other than the parties, the Snyder Indemnified Parties, the Patina Indemnified Parties and their respective successors and permitted assigns. 8. Waivers, Etc. No failure or delay on the part of the parties in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. No modification or waiver of any provision of this Agreement nor consent to any departure by the parties therefrom shall in any event be effective unless the same shall be in writing, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. 9. Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any thereof which may be hereafter declared invalid, void or unenforceable. In the event that any such term, provision, covenant or restriction is held to be invalid, void or unenforceable, the parties hereto shall use their reasonable efforts to find and employ an alternate means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. 10. Change of Law. If, due to any change in applicable law or regulations or the interpretation thereof by a court of law or other governing body having jurisdiction subsequent to the date of this Agreement, performance of any provision of this Agreement or any transaction contemplated hereby shall become impracticable or impossible, the parties hereto shall use their reasonable efforts to find and employ -5- an alternative means to achieve the same or substantially the same result as the contemplated by such provision. 11.
