(a) Seller shall be liable for, and shall defend, indemnify and hold Buyer harmless against, (i) any Taxes incurred by any of the Subsidiaries for any taxable period ending on or before the Closing Date, (ii) a portion, determined in the manner set forth in this Section 6.15, of any Taxes incurred by any of the Subsidiaries for any taxable period that includes the Closing Date but ends after the Closing Date ("Straddle Period"), (iii) any income Taxes caused by, or arising from, the Section 338(h)(10) Election, (iv) any transfer or sales Taxes arising from the transactions contemplated in this Agreement, other than transfer or sales Taxes that are imposed because of the Section 338(h)(10) Election if such -39- Taxes are in excess of the transfer or sales Taxes that would have been imposed if the Section 338(h)(10) Election had not been made, and (v) any Taxes imposed with respect to any payment from Seller under this sentence. Any Tax refunds received by the Buyer relating to the Tax liability of a Subsidiary for a period ending on or before the Closing Date shall be the property of the Seller other than Tax refunds generated because of a Buyer tax attribute. Seller will ensure that with respect to any Tax partnership listed on the Tax Certificate, the appropriate party has made or will make a valid election under Section 754 of the Code with respect to each such Tax partnership in the time and in the manner provided in Regulation ss. 1.754-1(b) such that each such election is in effect for the taxable year of each such Tax partnership that includes the Closing Date. (b) If a Straddle Period exists for any of the Subsidiaries for any Tax purpose, the Buyer, Seller, and such Subsidiary, to the extent permitted by law, shall elect to treat such period for purposes of this Agreement as consisting of two periods: (i) a period beginning with the first day of the Straddle Period and ending on the Closing Date ("Pre- Closing Period") and (ii) a period beginning immediately after the Closing Date and ending with the last day of the Straddle Period ("Post-Closing Period"). If applicable law does not permit such an election to be made, Taxes for the entire Straddle Period shall be apportioned between the Pre-Closing Period and the Post-Closing Period under the interim-closing-of- the-books method applied on the Closing Date, except that exemptions, allowances, deductions, and credits calculated under Applicable Law on an annual basis shall be apportioned on a per diem basis between these two periods. Seller shall be liable for the Taxes apportioned to the Pre-Closing Period. -40- (c) Seller shall prepare, or cause the Subsidiaries to prepare, and submit to Buyer all Tax Returns of the Subsidiaries (and any Tax partnerships in which (i) a Subsidiary owns an interest and (ii) Seller or a Subsidiary has responsibility for preparing and filing partnership Tax Returns) for Taxes for any taxable period ending on or before the Closing Date and for which the due date of any such Tax Return is subsequent to the Closing Date. Any such Tax Return shall be prepared on a basis consistent with Tax Returns prepared with respect to the Subsidiaries for prior taxable periods, unless otherwise required by law, and shall be submitted to Buyer not later than (i) in the case of any United States federal income or Canadian income Tax Return, 60 days before the due date of such Tax Return, and (ii) in the case of any other Tax Return, 30 days before the due date of such Tax Return. Seller is responsible for filing any such Tax Return and for preparing and filing any other Tax Return of the Subsidiaries for Taxes for any taxable period ending on or before the Closing Date. (d) Buyer and its Affiliates, including the Subsidiaries, are responsible for preparing and filing with the appropriate taxing authorities all Tax Returns which relate to the Taxes of the Subsidiaries other than those described in Section 6.15(c), except that Tax Returns which relate to a Post-Closing Period shall be completed by the Buyer. Seller shall cooperate with the Buyer and shall make available all necessary records and timely take all action necessary to allow Buyer to file, or prepare and file, as the case may be, the Tax Returns described in this paragraph (including, without limitation, providing or causing to be provided to Buyer any powers of attorney which Buyer shall request for purposes of filing any such Tax Returns). Such Tax Returns shall be prepared on a basis consistent with those -41- prepared with respect to the Subsidiaries for taxable periods ending on or before the Closing Date, unless otherwise required by law. (e) Notwithstanding any provision in this Section 6.15 to the contrary, the Buyer shall reimburse the Seller for certain Taxes, if any, incurred by the Seller in connection with the liability of an affiliated, combined, or unitary group of corporations with respect to the income, if any, of the Subsidiaries from the period from August 31, 1996, through the Closing Date in an amount equal to 37% of the net taxable income, reduced by all appropriate expenses, deductions and credits, of the Subsidiaries for such period determined in accordance with United States federal income tax principles ("Reimbursable Taxes"). The Buyer has an obligation to reimburse the Seller for such Reimbursable Taxes only if (i) the Seller submits, on or after the date the Seller filed all Tax returns relating to the period from August 31, 1996 through the Closing Date, to the Buyer a certificate (and such supporting documentation as the Buyer may reasonably request) prepared by the Seller setting forth the amount of such Reimbursable Taxes. If the Buyer disputes the amount of such Reimbursable Taxes set forth on such certificate, the parties shall submit the specific matters in dispute to the Auditors, or such independent accounting firm as may be approved by Seller and Buyer, which firm shall render its opinion as to such matters. Based on such opinion, such independent accounting firm will then send to Seller and Buyer its determination of the specified matters in dispute, which determination shall be final and binding on the parties hereto. The fees and expenses of the Auditors shall be borne one-half by Seller and one-half by Buyer. The Buyer shall make such reimbursement payment within 60 days of receiving the certificate and supporting documentation referred to in this Section 6.15(e), unless a dispute is submitted to the Auditors. If a dispute regarding the Reimbursable Taxes is -42- submitted to the Auditors, the payment, if any, shall be made within 15 days of the Auditors' decision. (f) Any payment made with respect to Taxes pursuant to this Section 6.15 shall be treated by Seller and Buyer as a nontaxable adjustment to the Purchase Price for the Shares. Section 6.16 Cooperation and Exchange of Information. The parties will provide each other with such cooperation and information as they may reasonably request of each other in preparing or filing any Tax Return, amended Tax Return or claim for refund, in determining a liability or a right to refund or in conducting any audit or other proceeding, in respect of Taxes imposed on the parties or their respective Affiliates. The Subsidiaries and each party will preserve and retain all Tax Returns, schedules, work papers and other documents relating to any such Tax Returns, claims, audits or other proceedings until the expiration of the statutory period of limitations (including extensions) of the taxable periods to which such documents relate and until the final determination of any payments which may be required with respect to such periods under this Agreement and shall make such documents available to representatives of Seller upon reasonable notice and at reasonable times, it being understood that such representatives shall be entitled to make copies of any such books and records as they shall deem necessary. Any information obtained pursuant to this Section 6.16 shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or claims for refund or in conducting any audit or other proceeding. Section 6.17 Conflict. In the event of a conflict between the provisions of Sections 6.13, 6.14, 6.15, or 6.16 and any other provision of this Agreement, the provisions of this Article VI shall control. -43- Section 6.18 Insurance. Buyer agrees to procure and maintain for three years after the Closing Date commercial general liability insurance and environmental liability insurance covering contractors' legal liability and professional/errors & omissions liability with no pollution exclusion with policy terms, conditions, exclusions, limits and deductibles not materially less favorable than such insurance maintained by Seller, as described in Schedule 6.18. ARTICLE VII Extent and Survival of Representations, Warranties, Covenants and Agreements; Indemnification Section 7.1 Indemnification of Buyer. Seller agrees to defend, indemnify and hold harmless Buyer (including its officers, directors, employees and agents and Affiliates) from and against, any and all claims, actions, causes of action, arbitrations, proceedings, losses, damages, liabilities, judgments and expenses (including, without limitation, reasonable attorneys' fees) ("Claim") incurred by Buyer, any Affiliate of Buyer, Seller or any Subsidiary as a result of (a) any error, inaccuracy, breach or misrepresentation in any of the representations and warranties made by or on behalf of Seller in this Agreement or in any certificate or other instrument delivered by or on behalf of Seller in connection with this Agreement (including the Schedules hereto), (b) any violation or breach by Seller of or default by Seller under the terms of this Agreement, (C) any act or omission occurring, or condition or circumstances existing, prior to the Closing, or any condition or circumstances caused by any act or omission occurring prior to the Closing, by Seller or any Subsidiary or otherwise with respect to Seller or any Subsidiary, (d) the past or present presence, release, remediation or clean-up of, or exposure to, Hazardous Material relating to or located on, -44- within or under any assets owned, leased or used by Seller or any Subsidiary, or (e) any product liability, strict liability or other claims concerning (i) products sold or services provided by Seller or any Subsidiary prior to the Closing or (ii) inventory owned by Seller or any Subsidiary at the Closing. Buyer shall be entitled to recover its reasonable and necessary attorneys' fees and litigation expenses incurred in connection with successful enforcement of its rights under this Section. Section 7.2 Survival; Threshold and Limits of Liability. (a) The representations, warranties and covenants in this Agreement and in any certificate or instrument delivered in connection herewith shall be continuing and shall survive the Closing until two years after the Closing Date (the period during which the representations and warranties shall survive being referred to herein with respect to such representations and warranties as the "Survival Period"), but shall thereafter terminate and be of no further force and effect unless a written notice asserting a claim shall have been made pursuant to this Article VII within the Survival Period with respect to such matter. Any claim for indemnification of a Claim of the type set forth in Section 7.1(a)-(d) of this Agreement (a "Section 7.1 Claim") made during the Survival Period shall remain in effect for purposes of such indemnification notwithstanding such claim may not be resolved within the Survival Period. Seller shall indemnify Buyer for any Section 7.1 Claim in an aggregate amount up to $1,000,000 in excess of any estimated liabilities accrued therefore by the Subsidiaries and transferred to Buyer and any insurance proceeds realized by Buyer in respect of such Claims net of any insurance premiums that become due as a result of such Claims. (b) Any claim for indemnification of Buyer for a Claim of the type set forth in Section 7.1(e) (a "Section 7.1(e) Claim") must be made no later than three years after -45- the Closing Date. Any such Claim shall remain in effect for purposes of such indemnification even if the Claim is not resolved within three years after the Closing Date. Seller shall indemnify Buyer for any Section 7.1(e) Claim up to an aggregate amount of $1,250,000 in excess of $659,650, representing the estimated liabilities accrued therefore by the Subsidiaries to be transferred to Buyer, and in excess of any insurance proceeds realized by Buyer in respect of Section 7.1(e) Claims net of any insurance premiums that become due as a result of such Claim. Section 7.3 Indemnification Procedures. All claims for indemnification under this Agreement shall be asserted and resolved as follows: (a) A party claiming indemnification under this Agreement (an "Indemnified Party") shall with reasonable promptness (i) notify the party from whom indemnification is sought (the "Indemnifying Party") of any third-party claim or claims asserted against the Indemnified Party ("Third Party Claim") for which indemnification is sought and (ii) transmit to the Indemnifying Party a copy of all papers served with respect to such claim (if any) and a written notice ("Claim Notice") containing a description in reasonable detail of the nature of the Third Party Claim, an estimate of the amount of damages attributable to the Third Party Claim to the extent feasible (which estimate shall not be conclusive of the final amount of such claim) and the basis of the Indemnified Party's request for indemnification under this Agreement. Within 15 days after receipt of any Claim Notice (the "Election Period"), the Indemnifying Party shall notify the Indemnified Party whether the Indemnifying Party disputes its potential liability to the Indemnified Party with respect to such Third Party Claim and, if the Indemnifying Party does not dispute its potential liability to the Indemnified Party with respect to -46- such Third Party Claim, whether the Indemnifying Party elects to defend the Indemnified Party with respect to such Third Party Claim. If the Indemnifying Party does not dispute its potential liability to the Indemnified Party within the Election Period and notifies the Indemnified Party that it elects to defend such Third Party Claim, the Indemnified Party shall control negotiations toward resolution of such claim without the necessity of litigation, and if litigation ensues, to defend the same with counsel reasonably acceptable to both parties, at the Indemnifying Party's expense, and the Indemnified Party shall extend reasonable cooperation in connection with such defense. The Indemnified Party shall be entitled to elect to participate in, but not to control, the defense of any Third Party Claim resulting in litigation, at its own cost and expense; provided, however, that if the parties to any suit or proceeding shall include the Indemnifying Party as well as the Indemnified Party and the Indemnified Party shall have been advised by counsel that one or more legal defenses may be available to it that may not be available to the Indemnifying Party, then the Indemnified Party shall be entitled to elect to control such suit or proceeding, but the Indemnifying Party shall be obligated to bear the fees and expenses of counsel of the Indemnified Party, which shall be selected by the Indemnified Party in its complete and sole discretion. If the Indemnifying Party does not dispute its potential liability to the Indemnified Party within the Election Period and the Indemnified Party fails to assume control of the negotiations prior to litigation or to defend such action within a reasonable time, the Indemnifying Party shall be entitled, but not obligated, to assume control of such negotiations or defense of such action, and the Indemnifying Party shall be liable to the Indemnified Party for its expenses reasonably incurred or amounts paid in connection therewith. If the Indemnifying Party disputes its potential liability to the Indemnified Party within the Election Period or does not elect to defend such Third Party Claim, then the Indemnified Party shall be -47- entitled to assume control of such negotiations or defense of action and the liability for the expense thereof, as well as any liability with respect to such Third Party Claim, shall be determined as provided in Section 7.4 below. If the Indemnifying Party fails to notify the Indemnified Party within the Election Period that the Indemnifying Party elects to defend the Indemnified Party pursuant to the preceding paragraph, or if the Indemnifying Party elects to defend the Indemnified Party but fails to prosecute or settle the Third Party Claim as herein provided, then the Indemnified Party shall have the right to defend, at the sole cost and expense of the Indemnifying Party (if the Indemnified Party is entitled to indemnification hereunder), the Third Party Claim by all appropriate proceedings, which proceedings shall be promptly and vigorously prosecuted by the Indemnified Party to a final conclusion or settled. The Indemnified Party shall have full control of such defense and proceedings. Notwithstanding the foregoing, if the Indemnifying Party has delivered a written notice to the Indemnified Party to the effect that the Indemnifying Party disputes its potential liability to the Indemnified Party under this Article VII and if such dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party shall not be required to bear the costs and expenses of the Indemnified Party's defense pursuant to this Section or of the Indemnifying Party's participation therein at the Indemnified Party's request, and the Indemnified Party shall reimburse the Indemnifying Party in full for all costs and expenses of such litigation. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section, and the Indemnifying Party shall bear its own costs and expenses with respect to such participation. Neither the Indemnifying Party nor the Indemnified Party shall settle, compromise, or make any other disposition of any Third Party Claim which would or might result -48- in any liability to the Indemnified Party or the Indemnifying Party under this Article VII without the written consent of such other party. (b) In the event any Indemnified Party should have a claim against any Indemnifying Party hereunder that does not involve a Third Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a written notice (the "Indemnity Notice") describing in reasonable detail the nature of the claim, an estimate of the amount of damages attributable to such claim to the extent feasible (which estimate shall not be conclusive of the final amount of such claim) and the basis of the Indemnified Party's request for indemnification under this Agreement. If the Indemnifying Party does not notify the Indemnified Party within 15 days from its receipt of the Indemnity Notice that the Indemnifying Party disputes such claim, the claim specified by the Indemnified Party in the Indemnity Notice shall be deemed a liability of the Indemnifying Party hereunder. Section 7.4 Arbitration of Disputes. If the Indemnifying Party disputes, either as to the amount or liability, that any claim described in a Claim Notice or an Indemnity Notice, as the case may be, is covered by such Indemnifying Party's covenant to indemnify contained in this Article VII, then the Indemnifying Party and the Indemnified Party agree to promptly negotiate in good faith to resolve their differences and to mutually agree upon an amount, if any, owed to Indemnified Party by the Indemnifying Party hereunder. If Indemnifying Party and Indemnified Party fail to agree within 30 days thereafter, the dispute shall be resolved by binding and final arbitration of a single arbitrator mutually agreed to by Buyer and Seller conducted in Houston, Texas in accordance with the rules of commercial arbitration of the American Arbitration Association. The prevailing party in any such arbitration proceeding shall be entitled to attorneys' -49- fees and other out-of-pocket expenses reasonably and necessarily incurred in connection with such proceeding, the amounts of which shall be contained in the award of the arbitrator. Section 7.5 General. The covenants and agreements entered into pursuant to this Agreement to be performed after the Closing shall survive the Closing without limitation. The indemnification obligations under this Article VII shall apply regardless of whether any Claim results solely or in part from the active, passive or concurrent negligence of the Indemnified Party or a Subsidiary prior to the Closing Date. The parties agree that this Article VII does not entitle the Buyer to indemnification for the Buyer's or a Subsidiary's act or omission after the closing Date. The rights of the parties to indemnification under this Article VII shall not be limited due to any investigations heretofore or hereafter made by such parties or their representatives, regardless of negligence in the conduct of any such investigations. All representations, warranties and covenants and agreements made by the parties shall not be deemed merged into any instruments or agreements delivered in connection with the Closing or otherwise in connection with the transactions contemplated hereby. Section 7.6 Security. Seller agrees that it shall not effect its liquidation, dissolution, change of control, merger or sale of all or a substantial portion of its assets, or any event causing it to cease to exist, without assigning its obligations under this Section VII to a third party acceptable to Buyer and/or posting security for such indemnification obligations, in each case, to Buyer's reasonable satisfaction sufficient to cover Seller's obligations hereunder throughout the period of time such obligations exist. -50- ARTICLE VIII Conditions to Closing Section 8.1 Conditions Precedent to Obligations of Buyer.
