be either generally applicable or applicable only in specific cases.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(d) | The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ or service of the Company or any Affiliate. Further, the
Company or any Affiliate may at any time dismiss a Participant from employment free from any liability, or any claim under the Plan, unless otherwise expressly provided in the Plan or in any Award Agreement or in any other agreement binding the
parties.

|(e) | If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction, or as to any person or Award, or
would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws, or if it cannot be so construed or deemed amended without, in the

Affiliate and a Participant or any other person. To the extent that any person acquires a right to receive payments from the Company or an Affiliate pursuant to an Award, such right shall be no greater than the right of any unsecured general
creditor of the Company.
