ITEM 5.02 Departure of Directors or Certain Officers; Election of
Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(e) In December 2008, Arch Capital Group Ltd. ("ACGL") and its subsidiaries (together with ACGL, the "Company') merged two of its non-qualified tax deferred compensation plans into one plan and brought the terms of the combined plan into compliance with Section 409A of the Internal Revenue Code of 1986, as amended. Following that process, on December 11, 2008, the Company adopted a plan amendment pursuant to which ACGL will credit to an account in the plan $2,466,526 on behalf of Dinos Iordanou, President and Chief Executive Officer of ACGL. The Company authorized this contribution to Mr. Iordanou's account in connection with the renewal of his employment agreement to provide supplemental pension benefits for services performed by him prior to the contribution date and in recognition that certain pension benefits from his former employer were previously foregone by Mr. Iordanou. The credited amount will be fully vested on the contribution date. The credited amount, together with any notional earnings credited under the terms of the plan, will be distributed to Mr. Iordanou on or before December 31, 2017 in accordance with his distribution election and the provisions of the plan.
