Re: Amendment to Letter of Assignment

Dear Stephen:

On behalf of the XL Group plc and XL Services (Bermuda) Ltd (collectively, the
“Company”), I am writing pursuant to Section 13 of the Letter of Assignment
between you and the Company, which became effective on 1 May 2015 (“Letter of
Assignment”), to confirm our mutual agreement to several amendments which will
be effective as of the date hereof, to wit:
    
1.
Section 2(a) of the Letter of Assignment is amended to remove “USD $1,000,000”
and replace it with “USD $1,300,000” with effect from 1 September 2015.

2.
Section 2(b) of the Letter of Assignment is amended to remove the final sentence
of that sub-section in its entirety and replace it with the following sentence:
“Your target bonus opportunity shall be USD $2,000,000.”

This amendment letter is final and binding on all parties with respect to its
subject matter. All other provisions contained in the Letter of Assignment
remain in full force and effect as if fully set forth in this letter of
amendment.

If you are in agreement with these amendments to the Letter of Assignment,
please sign the agreement below and return a copy to me. We will return a fully
executed copy to you for your records.

    

Thank you for your thoughtful attention to this matter.
