Spouse – means a person who is legally married to a Participant under the laws of any domestic or foreign jurisdiction that has the legal authority to sanction marriages.

8.8. Applicable Law. The SERP and all rights hereunder shall be governed by and construed in accordance with the laws of the State of Florida (without regard to principles of conflicts of law) to the extent such laws have not been preempted by applicable federal law. Venue for any action arising under the SERP shall be in Brevard County, Florida.

4. Effective as of the date hereof, Article VIII hereby is amended to add the following new Section 8.10 thereto:

8.10. Legal Fees. Any award of legal fees in connection with an action involving the SERP shall be calculated pursuant to a method that results in the lowest amount of fees being paid, which amount shall be no more than the amount that is reasonable. In no event shall legal fees be awarded for work related to:

(a) administrative proceedings under the SERP;
