Subject to Section 6, Consultant’s provision of the services specified under the terms of this Agreement shall commence on the first calendar day after the Retirement Date (such date, the “Effective Date”), and shall continue until the third anniversary of the Effective Date (the “Initial Term”) unless earlier terminated in accordance with the applicable provisions of this Agreement. Subject to Section 6, upon the expiration of the Initial Term, this Agreement shall automatically renew for successive one-year terms, unless and until either party provides written notice of non-renewal to the other party at least thirty (30) before the end of the then current Initial Term or renewal term.

In no event shall Consultant perform Services hereunder at a level that would require Consultant to devote to such Services twenty percent (20%) or more of the average level of bona fide services performed by Consultant while an employee of any member of the Company Group over the 36-month period immediately preceding the Retirement Date.
