Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Restricted stock units awarded pursuant to the Assured Guaranty Ltd. 2004 Long-Term Incentive Plan (the "Plan"). With limited exceptions, the restricted stock units vest on 2/7/2016, assuming that the holder remains employed at such time. Upon vesting, one Common Share will be delivered for each vested restricted stock unit.
(2)	Stock options awarded pursuant to the Plan. With limited exceptions, the options become exercisable on 2/7/2016, if at all, at the end of the performance period (1/1/2013 to 12/31/2015), assuming that the holder remains employed at such time, based on the Company's Common Share price using the highest 40-day average stock price during the performance period as follows: 100% if the share price reaches $30; 50% if the share price reaches $24; and 35% if the share price reaches $18 (with interpolation between those prices). If the share price does not reach $18, none of the options will vest.
(3)	Total includes options from other tranches with different exercise prices, vesting terms and expiration dates.
(4)	Performance share units awarded pursuant to the Plan. Each performance share unit represents a contingent right to receive one Common Share of the Company. With limited exceptions, the performance share units vest on 2/7/2016, if at all, at the end of the performance period (1/1/2013 to 12/31/2015), assuming that the holder remains employed at such time, based on the Company's Common Share price using the highest 40-day average stock price during the three year performance period as follows: 200% if the share price reaches $30; 100% if the share price reaches $24; and 35% if the share price reaches $18 (with interpolation between those prices). If the share price does not reach $18, none of the performance share units will vest.
(5)	To the extent unvested performance share units do not become vested units at the end of the applicable performance period as described above, such unvested performance share units will expire at the end of such performance period. Upon vesting, one Common Share will be delivered for each vested performance share unit.
