As used in this Plan, "Company" shall mean the Company as hereinbefore defined and any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by operation of law, or otherwise. (b) Concurrently with any merger, consolidation, share exchange or sale, lease or transfer of all or substantially all of its assets, the Company will cause any successor or transferee unconditionally to assume all of the obligations of the Company hereunder.

Governing Law; Validity. (a) The interpretation, construction and performance of this Plan, unless pre-empted by the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), shall be governed by and construed and enforced in accordance with the laws of the State of Colorado without regard to the principle of conflicts of laws.

Miscellaneous. (a) This Plan is an unfunded plan maintained by the Company primarily for the purpose of providing deferred compensation to the Participant, a member of a select group of management or highly compensated employees. To the extent that any person acquires a right to receive payments from the Company under this Plan, such right shall be no greater than the right of any unsecured general creditor of the Company. The Company shall not be required to fund or otherwise segregate assets to be used for the payment of any benefits under the Plan. The Company shall make such payments only out of its general corporate funds, and therefore its obligation to make such payments shall be subject to any claims of its other creditors having priority as to its assets. (b) This Plan does not constitute a contract of employment or impose on the Company any obligation to retain such Participant as an employee, to change the status of such Participant's employment, or to change the policies of the Company regarding termination of employment. (c) No rights of any Participant (or Beneficiary) to payments of any amounts under the Plan shall be sold, exchanged, transferred, assigned, pledged, hypothecated or otherwise disposed of other than by will or by the laws of descent and distribution, and any such purported sale, exchange, transfer, assignment, pledge, hypothecation or disposition shall be void. The Company shall not recognize any purported sale, exchange, transfer, assignment, pledge, hypothecation, or disposition by any Participant of all or part of his interest hereunder, and such interest shall not be subject in any manner to transfer by operation of law, and shall be exempt from the claims of creditors or other claimants from all orders, decrees, levies, garnishment and/or executions and other legal or equitable process or proceedings against the Participant to the fullest extent which may be permitted by law. (d) Unless the Company specifically provides otherwise, any benefits payable under this Plan shall not be taken into account for purposes of determining benefits payable to the Participant under any other benefit plan or program.
