Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee is hereby authorized to make equitable adjustments in the terms and conditions of, and the criteria included in, all outstanding Awards in recognition of unusual or nonrecurring events (including, without limitation,
the events described in Section 4(b) hereof) affecting the Company, any Affiliate, or the financial statements of the Company or any Affiliate, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan; provided that no such adjustment shall be authorized to the extent that such authority or adjustment would cause an Award designated by the Committee as a Performance Compensation Award under Section 11 of the Plan to fail to qualify as performance-based compensation under Section 162(m) of the Code.
Section 13. Change of Control. In the event of a Change of Control, any outstanding Awards then held by Participants which are unexercisable or otherwise unvested shall automatically be deemed exercisable or otherwise vested, as the case may be, effective as of immediately prior to such Change of Control, unless the terms of the Award Agreement expressly provides to the contrary.
Section 14. General Provisions.
