Arbitration. 14.1 If a dispute arises out of or related to this Agreement and the dispute cannot be settled through direct discussions, Company and Employee agree that they shall first endeavor to settle the dispute in an amicable fashion. If such efforts fail to resolve the dispute, the dispute shall, except as otherwise provided in paragraph 18, be resolved as follows: 14.1.1 Except as provided in paragraph 14.1.2 below, any and all claims, demands, cause of action, disputes, controversies, and other matters in question arising out of or relating to this Agreement, any provision hereof, the alleged breach thereof, or in any way relating to the subject matter of this Agreement, involving Company, Employee, and/or their respective representatives, even though some or all of such claims allegedly are extracontractual in nature, whether such claims sound in contract, tort, or otherwise, at law or in equity, under state or federal law, whether provided by statute or the common law, for damages or any other relief, shall be resolved by binding arbitration pursuant to the Federal Arbitration Act in accordance with the Commercial Arbitration Rules then in effect with the American Arbitration Association (the "AAA"). The arbitration proceeding shall be conducted in Houston, Texas. The arbitration may be initiated by either party by providing to the other a written notice of arbitration specifying the claims, and the parties shall thereafter endeavor to agree on an arbitrator. If within thirty (30) days of the notice of initiation of the arbitration procedure, the parties are unable to agree on an arbitrator, the party requesting arbitration shall file a request with the AAA that the Houston, Texas office of the AAA provide a list of potential arbitrators to both parties. The parties shall thereafter have sixty (60) days to select an arbitrator from such list, with such selection to be by mutual agreement. If the parties fail to select an arbitrator within such time by mutual agreement, then either party may request that the Chief Judge of the U.S. District Court for the Southern District of Texas appoint an arbitrator, and any such appointment shall be binding. The arbitrator, utilizing the Commercial Arbitration Rules of the American Arbitration EMPLOYMENT AGREEMENT--CHRISTOPHER E. LINDSEY -8- 9 Association, shall within 120 days of his or her selection, resolve all disputes between the parties. There shall be no transcript of the hearings before the arbitrator. The arbitrator's decision shall be in writing, but shall be as brief as possible. The arbitrator shall not assign the reasons for his or her decision. The arbitrator's decision shall be final and non-appealable to the maximum extent permitted by law. Judgment upon any award rendered in any such arbitration proceeding may be entered by any federal or state court having jurisdiction. This agreement to arbitrate shall be enforceable in either federal or state court. The enforcement of this agreement to arbitrate and all procedural aspects of this agreement to arbitrate, including but not limited to, the construction and interpretation of this agreement to arbitrate, the issues subject to arbitration (i.e., arbitrability), the scope of the arbitrable issues, allegations of waiver, delay or defenses to arbitrability, and the rules governing the conduct of the arbitration, shall be governed by and construed pursuant to the Federal Arbitration Act and shall be decided by the arbitrator. In deciding the substance of any such claims, the arbitrator shall apply the substantive laws of the State of Texas (excluding Texas choice-of-law principles that might call for the application of some other State's law); provided, however, it is expressly agreed that the arbitrator shall have no authority to award treble, exemplary, or punitive damages under any circumstances regardless of whether such damages may be available under Texas law, the parties hereby waiving their right, if any, to recover treble, exemplary, or punitive damages in connection with any such claims. 14.1.2 Notwithstanding the agreement to arbitrate contained in paragraph 14.1.1 above, in the event that either party wishes to seek a temporary restraining order, a preliminary or temporary injunction, or other injunctive relief in connection with any or all such claims, demands, cause of action, disputes, controversies, and other matters in question arising out of or relating to this Agreement, any provision hereof, the alleged breach thereof, or in any way relating to the subject matter of this Agreement, involving Company, Employee, and/or their respective representatives, including disputes arising out of a breach or alleged breach of paragraph 4, even though some or all of such claims allegedly are extra-contractual in nature, whether such claims sound in contract, tort, or otherwise, at law or in equity, under state or federal law, whether provided by statute or the common law, for damages or any other relief, each party shall have the right to pursue such injunctive relief in court, rather than by arbitration. The parties agree that such action for a temporary restraining order, a preliminary EMPLOYMENT AGREEMENT--CHRISTOPHER E. LINDSEY -9- 10 or temporary injunction, or other injunctive relief will be brought in the State or federal courts residing in Houston, Harris County, Texas. 14.2 The Company shall pay all costs and expenses of Company and Employee (including, but not limited to, attorneys' fees, the fees of the arbitrator and the AAA and any other related costs) for any arbitration proceeding or legal action; provided, however, that if in any such arbitration proceeding or legal action, the arbitrator or court, respectively, determines that Employee has prosecuted or defended any issue in such proceeding or action in bad faith, the arbitrator or court, respectively, may allocate the portion of such costs and expenses relating to such issue between the parties in any other manner deemed fair, equitable and reasonable by the arbitrator or court, respectively. 15. Foreign Corrupt Practices Act. Employee shall at all times comply with the United States Foreign Corrupt Practices Act, generally codified in 15 USC 78 (FCPA), as the FCPA may hereafter be amended, and/or its successor statutes. If Employee pleads guilty to or nolo contendere or admits civil or criminal liability under the FCPA, or if a court finds that Employee committed an action resulting in any Company entity having civil or criminal liability or responsibility under the FCPA with knowledge of the activities giving rise to such liability or knowledge of facts from which Employee should have reasonably inferred the activities giving rise to liability had occurred or were likely to occur, such action or finding shall constitute Cause for termination by Company under paragraph 3.3 of this Agreement unless Company's Board of Directors determines that the actions found to be in violation of the FCPA were taken in good faith and in compliance with all applicable policies of Company. 16. Survival. The provisions of paragraphs 4 and 20 shall survive any termination of the employment relationship and/or of this Agreement for the periods stated therein. The provisions of paragraph 14 relating to arbitration shall survive any termination of the employment relationship between Employee and Company and the termination of this Agreement. Amounts, compensation, rights and benefits which Employee is entitled to receive or have accrued to Employee under this Agreement or under any plan, program, arrangement, agreement or policy of or with Company or any of its affiliates before, at or subsequent to the termination of the employment relationship between Employee and Company or the termination of this Agreement shall not be superseded and shall survive any such termination. EMPLOYMENT AGREEMENT--CHRISTOPHER E. LINDSEY -10- 11 17. Certain Additional Payments by Company. 17.1 Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by Company or any of its affiliates to or for the benefit of Employee, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (any such payments or distributions being individually referred to herein as a "Payment," and any two or more of such payments or distributions being referred to herein as "Payments"), would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code") (such excise tax, together with any interest thereon, any penalties, additions to tax, or additional amounts with respect to such excise tax, and any interest in respect of such penalties, additions to tax or additional amounts, being collectively referred herein to as the "Excise Tax"), then Employee shall be entitled to receive an additional payment or payments (individually referred to herein as a "Gross-Up Payment" and any two or more of such additional payments being referred to herein as "Gross-Up Payments") in an amount such that after payment by Employee of all taxes (as defined in paragraph 17.11) imposed upon the Gross-Up Payment, Employee retains an amount of such Gross-Up Payment equal to the Excise Tax imposed upon the Payments. 17.2 Subject to the provisions of paragraph 17.3 through 17.11, any determination (individually, a "Determination") required to be made under this paragraph 17, including whether a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall initially be made, at Company's expense, by nationally recognized tax counsel mutually acceptable to Company and Employee ("Tax Counsel"). Tax Counsel shall provide detailed supporting legal authorities, calculations, and documentation both to Company and Employee within 15 business days of the termination of Employee's employment, if applicable, or such other time or times as is reasonably requested by Company or Employee. If Tax Counsel makes the initial Determination that no Excise Tax is payable by Employee with respect to a Payment or Payments, it shall furnish Employee with an opinion reasonably acceptable to Employee that no Excise Tax will be imposed with respect to any such Payment or Payments. Employee shall have the right to dispute any Determination (a "Dispute") within 15 business days after delivery of Tax Counsel's opinion with respect to such Determination. The Gross-Up Payment, if any, as determined pursuant to such Determination shall be paid by Company to Employee within five business days of Employee's receipt of such Determination. The existence of a Dispute shall not in any way affect Employee's right to receive the Gross-Up Payment in accordance with such Determination. If there is no Dispute, such Determination shall be binding, final and conclusive upon Company and Employee, subject in all respects, EMPLOYMENT AGREEMENT--CHRISTOPHER E. LINDSEY -11- 12 however, to the provisions of paragraph 17.3 through 17.11 below. As a result of the uncertainty in the application of Sections 4999 and 280G of the Code, it is possible that Gross-Up Payments (or portions thereof) which will not have been made by Company should have been made ("Underpayment"), and if upon any reasonable written request from Employee or Company to Tax Counsel, or upon Tax Counsel's own initiative, Tax Counsel, at Company's expense, thereafter determines that Employee is required to make a payment of any Excise Tax or any additional Excise Tax, as the case may be, Tax Counsel shall, at Company's expense, determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by Company to Employee. 17.3 Company shall defend, hold harmless, and indemnify Employee on a fully grossed-up after tax basis from and against any and all claims, losses, liabilities, obligations, damages, impositions, assessments, demands, judgements, settlements, costs and expenses (including reasonable attorneys', accountants', and experts' fees and expenses) with respect to any tax liability of Employee resulting from any Final Determination (as defined in paragraph 17.10) that any Payment is subject to the Excise Tax. 17.4 If a party hereto receives any written or oral communication with respect to any question, adjustment, assessment or pending or threatened audit, examination, investigation or administrative, court or other proceeding which, if pursued successfully, could result in or give rise to a claim by Employee against Company under this paragraph 17 ("Claim"), including, but not limited to, a claim for indemnification of Employee by Company under paragraph 17.3, then such party shall promptly notify the other party hereto in writing of such Claim ("Tax Claim Notice"). 17.5 If a Claim is asserted against Employee ("Employee Claim"), Employee shall take or cause to be taken such action in connection with contesting such Employee Claim as Company shall reasonably request in writing from time to time, including the retention of counsel and experts as are reasonably designated by Company (it being understood and agreed by the parties hereto that the terms of any such retention shall expressly provide that Company shall be solely responsible for the payment of any and all fees and disbursements of such counsel and any experts) and the execution of powers of attorney, provided that: 17.5.1 within 30 calendar days after Company receives or delivers, as the case may be, the Tax Claim Notice relating to such Employee Claim (or such earlier date that any payment of the taxes claimed is due from Employee, but in no event sooner than five calendar days after Company receives or delivers such Tax Claim Notice), Company EMPLOYMENT AGREEMENT--CHRISTOPHER E. LINDSEY -12- 13 shall have notified Employee in writing ("Election Notice") that Company does not dispute its obligations (including, but not limited to, its indemnity obligations) under this Agreement and that Company elects to contest, and to control the defense or prosecution of, such Employee Claim at Company's sole risk and sole cost and expense; and 17.5.2 Company shall have advanced to Employee on an interest-free basis, the total amount of the tax claimed in order for Employee, at Company's request, to pay or cause to be paid the tax claimed, file a claim for refund of such tax and, subject to the provisions of the last sentence of paragraph 17.7, sue for a refund of such tax if such claim for refund is disallowed by the appropriate taxing authority (it being understood and agreed by the parties hereto that Company shall only be entitled to sue for a refund and Company shall not be entitled to initiate any proceeding in, for example, United States Tax Court) and shall indemnify and hold Employee harmless, on a fully grossed-up after tax basis, from any tax imposed with respect to such advance or with respect to any imputed income with respect to such advance; and 17.5.3 Company shall reimburse Employee for any and all costs and expenses resulting from any such request by Company and shall indemnify and hold Employee harmless, on fully grossed-up after-tax basis, from any tax imposed as a result of such reimbursement. 17.6 Subject to the provisions of paragraph 17.5 hereof, Company shall have the right to defend or prosecute, at the sole cost, expense and risk of Company, such Employee Claim by all appropriate proceedings, which proceedings shall be defended or prosecuted diligently by Company to a Final Determination; provided, however, that (i) Company shall not, without Employee's prior written consent, enter into any compromise or settlement of such Employee Claim that would adversely affect Employee, (ii) any request from Company to Employee regarding any extension of the statute of limitations relating to assessment, payment, or collection of taxes for the taxable year of Employee with respect to which the contested issues involved in, and amount of, the Employee Claim relate is limited solely to such contested issues and amount, and (iii) Company's control of any contest or proceeding shall be limited to issues with respect to the Employee Claim and Employee shall be entitled to settle or contest, in his sole and absolute discretion, any other issue raised by the Internal Revenue Service or any other taxing authority. So long as Company is diligently defending or prosecuting such Employee Claim, Employee shall provide or cause to be provided to Company any information reasonably requested by Company that relates to such Employee Claim, and shall otherwise cooperate with Company and its EMPLOYMENT AGREEMENT--CHRISTOPHER E. LINDSEY -13- 14 representatives in good faith in order to contest effectively such Employee Claim. Company shall keep Employee informed of all developments and events relating to any such Employee Claim (including, without limitation, providing to Employee copies of all written materials pertaining to any such Employee Claim), and Employee or his authorized representatives shall be entitled, at Employee's expense, to participate in all conferences, meetings and proceedings relating to any such Employee Claim. 17.7 If, after actual receipt by Employee of an amount of a tax claimed (pursuant to an Employee Claim) that has been advanced by Company pursuant to paragraph 17.5.2 hereof, the extent of the liability of Company hereunder with respect to such tax claimed has been established by a Final Determination, Employee shall promptly pay or cause to be paid to Company any refund actually received by, or actually credited to, Employee with respect to such tax (together with any interest paid or credited thereon by the taxing authority and any recovery of legal fees from such taxing authority related thereto), except to the extent that any amounts are then due and payable by Company to Employee, whether under the provisions of this Agreement or otherwise. If, after the receipt by Employee of an amount advanced by Company pursuant to paragraph 17.5.2, a determination is made by the Internal Revenue Service or other appropriate taxing authority that Employee shall not be entitled to any refund with respect to such tax claimed and Company does not notify Employee in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of any Gross-Up Payments and other payments required to be paid hereunder. 17.8 With respect to any Employee Claim, if Company fails to deliver an Election Notice to Employee within the period provided in paragraph 17.5.1 hereof or, after delivery of such Election Notice, Company fails to comply with the provisions of paragraph 17.5.2, 17.5.3 or 17.6 hereof, then Employee shall at any time thereafter have the right (but not the obligation), at his election and in his sole and absolute discretion, to defend or prosecute, at the sole cost, expense and risk of Company, such Employee Claim. Employee shall have full control of such defense or prosecution and such proceedings, including any settlement or compromise thereof. If requested by Employee, Company shall cooperate, and shall cause its affiliates to cooperate, in good faith with Employee and his authorized representatives in order to contest effectively such Employee Claim. Company may attend, but not participate in or control, any defense, prosecution, settlement or compromise of any Employee Claim controlled by Employee pursuant to this paragraph 17.8 and shall bear its own costs and expenses with respect thereto. In the case of any Employee EMPLOYMENT AGREEMENT--CHRISTOPHER E. LINDSEY -14- 15 Claim that is defended or prosecuted by Employee, Employee shall, from time to time, be entitled to current payment, on a fully grossed-up after tax basis, from Company with respect to costs and expenses incurred by Employee in connection with such defense or prosecution. 17.9 In the case of any Employee Claim that is defended or prosecuted to a Final Determination pursuant to the terms of this paragraph 17.9, Company shall pay, on a fully grossed-up after tax basis, to Employee in immediately available funds the full amount of any taxes arising or resulting from or incurred in connection with such Employee Claim that have not theretofore been paid by Company to Employee, together with the costs and expenses, on a fully grossed-up after tax basis, incurred in connection therewith that have not theretofore been paid by Company to Employee, within ten calendar days after such Final Determination.
