(b)           Arbitrator.  The arbitrator shall be a retired superior or appellate court judge of the State of Texas affiliated with JAMS.

4

(c)           Provisional Remedies and Appeals.  Each of the parties reserves the right to file with a court of competent jurisdiction an application for temporary or preliminary injunctive relief, writ of attachment, writ of possession, temporary protective order and/or appointment of a receiver on the grounds that the arbitration award to which the applicant may be entitled may be rendered ineffectual in the absence of such relief.  The award of the arbitrator shall be binding, final, and nonappealable.

(d)           Enforcement of Judgment.  Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.  The award of the arbitrator shall be binding, final, and nonappealable.

(e)           Discovery.  The parties may obtain discovery in aid of the arbitration to the fullest extent permitted under law.  All discovery disputes shall be resolved by the arbitrator.

(f)            Consolidation.  Any arbitration hereunder may be consolidated by JAMS with the arbitration of any other dispute arising out of or relating to the same subject matter when the arbitrator determines that there is a common issue of law or fact creating the possibility of conflicting rulings by more than one arbitrator.  Any disputes over which arbitrator shall hear any consolidated matter shall be resolved by JAMS.

(g)           Power and Authority of Arbitrator.  The arbitrator shall not have any power to alter, amend, modify or change any of the terms of this Agreement nor to grant any remedy which is either prohibited by the terms of this Agreement, or not available in a court of law.

(h)           Governing Law.  All questions in respect of procedure to be followed in conducting the arbitration as well as the enforceability of this Agreement to arbitrate which may be resolved by state law shall be resolved according to the law of the state of Delaware.  Any action brought to enforce the provisions of this Section shall be brought in the Harris County Superior Court.  All other questions in respect to this Agreement, including but not limited to the interpretation, enforcement of this Agreement (other than the right to arbitrate), and the rights, duties and liabilities of the parties to this Agreement shall be governed by Delaware law.

(i)            Costs.  The costs of the arbitration, including any JAMS administration fee, and arbitrator’s fee, and costs of the use of facilities during the hearings, shall be borne equally by the parties in the first instance.  Upon issuance of an award, costs shall be awarded to the prevailing party.

3.8           Attorneys’ Fees.  If a party to this Agreement shall bring any action, suit, counterclaim, appeal, arbitration, or mediation for any relief against the other parties, declaratory or otherwise, to enforce the terms hereof or to declare rights hereunder (referred to herein as an “Action”), the non-prevailing party in such Action shall pay to the prevailing party in such Action a reasonable sum for the prevailing party’s attorneys’ fees and expenses (at the prevailing party’s attorneys’ then-current rates, as increased from time to time by the giving of advance written notice by such counsel to such party) incurred in prosecuting or defending such Action and/or enforcing any judgment, order, ruling or award (referred to herein as a “Decision”), granted therein, all of which shall be deemed to have accrued from the commencement of such Action, and shall be paid whether or not such Action is prosecuted to a Decision.  Any Decision entered into in such Action shall contain a specific provision providing for the recovery of attorneys’ fees and expenses incurred in enforcing such Decision.  The court or arbitrator may fix the amount of reasonable attorneys’ fees and expenses upon the request of any party.  For purposes of this Section, attorneys’ fees shall include, without limitation, fees incurred in connection with (1) postjudgment motions and collection actions, (2) contempt proceedings, (3) garnishment, levy and debtor and third party examination, (4) discovery and (5) bankruptcy litigation.

3.9           Submission to Jurisdiction.  Subject to the provisions of Section 3.7 above, each of the Parties submits to the exclusive jurisdiction of any federal court sitting in the State of Texas, County of Harris, in any action or proceeding arising out of or relating to this Agreement and agrees that all claims in respect of the action or proceeding may be heard and determined in any such court.  Each Party also agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court.  Each of the parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety, or other security that might be required of the other Party with respect thereto.  Either Party may make service on the other Party by sending or delivering a copy of the process to the Party to be served at the address and in the manner provided for the giving of notices in Section 9.7 of the Purchase Agreement.  Nothing in this Section 3.9, however, shall affect the right of either Party to serve legal process in any other manner permitted by law or at equity.  Each party agrees that a final judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law or at equity.

3.10         No Waiver.  No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.  The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

3.11         Counterparts.  This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

3.12         Purchase Agreement.  All references to the Purchase Agreement herein shall be to such agreement as may be amended by the parties thereto from time to time.

6

3.13         Certain Events.  The Stockholders agree that this Agreement and the obligations hereunder shall attach to the Shares and shall be binding upon any person to which legal or beneficial ownership of such Shares shall pass, whether by operation of law or otherwise, including without limitation, any such Stockholders’ spouses, trustees, beneficiaries, heirs, guardians, administrators or successors.  Notwithstanding any such transfer of Shares, the transferor shall remain liable for the performance of all obligations under this Agreement.  This Agreement and the obligations hereunder, so long as any Stockholder is an individual, will survive the death, incompetency and disability of such Stockholder or any other individual holder of the Shares, so long as any Stockholder is an entity, will survive the merger or reorganization of such Stockholder, so long as any Stockholder is a trust, will survive the dissolution of such Stockholder.
