2. Rights of Participants. Nothing in the Agreement or in any grant thereunder shall confer any right on a participant to continue in the service or employ as a director or officer of or in the performance of services for the Company or a Subsidiary or shall interfere in any way with the right of the Company or a Subsidiary to terminate the employment or performance of services or to reduce the compensation or responsibilities of a participant at any time.

3. Remedies. The parties hereto shall be entitled to enforce their rights under this Agreement specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights existing in their favor.
