“Notwithstanding the foregoing, the Executive’s title, responsibilities, power and duties may be changed by the Company prior to the end of the Employment Period, consistent with the transition of his position to a successor.”

I am pleased to confirm our offer of employment to you for the position of Senior Advisor, Arch Capital Group Ltd. (the “Company”). Confirming our discussions, your new employment terms will commence on January 1, 2022 and continue through December 31, 2022, unless terminated earlier by the Company for Cause (as defined in your Employment Agreement with the Company dated February 1, 2018, as amended (the “Employment Agreement”)) or due to your permanent disability or death. The term of such employment may be extended if mutually agreed in writing by you and the Company.

During the term of your employment under this letter agreement, you are expected to provide services to the Company on a part time basis working approximately 25 to 30 percent of a normal work week, as reasonably requested by the Company. You will receive a base salary at an annual rate of

$150,000 payable in semi‐monthly installments on the 15th and last working day of each month. You will be eligible to receive an annual performance bonus based upon the Company’s and your individual performance, as determined by the Board of Directors of the Company in its discretion. Your target bonus for performance year 2022 (payable in March 2023) will be 100% of your annual base salary set forth above ($150,000). Provided you continue to be employed by the Company through the date of grant, during February of 2022 you will also receive a one‐time grant of restricted common shares of the Company and/or options to purchase common shares of the Company having an aggregate value, as determined by the Company, of $150,000 on the grant date. However, you will not otherwise be eligible to participate in the Company’s Long Term Incentive and Share Award Plans (or any similar plan adopted by the Company) under which share‐based awards may be granted. All amounts of compensation paid to you shall be paid subject to applicable taxes and deductions.

You will continue to be eligible for coverage under the Company’s group medical, life insurance and disability insurance programs (subject, in each case, to the applicable plan documents). You will also be entitled to benefits under any plan or arrangement available generally for the employees of the Company (subject to the applicable plan documents).

Articles 6 through 12 of the Employment Agreement shall remain in effect in accordance with their terms during the term of your employment under this letter agreement and following any termination of your employment, except that the Noncompetition Period in Section 9.01 of the Employment Agreement shall end on the date you are no longer employed by the Company.

This letter agreement will be governed by the laws of Bermuda without regard to principles of conflict of laws thereof, and it will bind and inure to the benefit of the successors and assigns of the

Company. You may not assign your rights or delegate your obligations hereunder without the written consent of the Company. This letter agreement and the surviving provisions of the Employment Agreement constitute the entire agreement among the parties hereto relating to the subject matter hereof and supersede any prior understandings, agreements or representations by or among the parties, written or oral, that may have related in any way to the subject matter hereof. For the avoidance of doubt, in the event the Employment Period under the Employment Agreement terminates following the provision of notice of termination as set forth in any of Section 5.01(b) through (f) thereof or due to your death, this letter agreement shall have no force or effect.

Please acknowledge your acceptance of this offer by signing and returning this letter agreement to Jennifer Centrone.
