Assured Guaranty Ltd. Announces Agreement with WL Ross & Co. LLC to Purchase Up To Five Million Additional Common Shares of Assured

"We appreciate the continued support of WL Ross as it reflects confidence in the long term prospects of Assured and also recognizes the significant value in our stock and Company through these turbulent times," commented Dominic Frederico, President and Chief Executive Officer of Assured Guaranty Ltd. "We look forward to continuing to work with Wilbur Ross who is also a member of our Board in order to further develop Assured's financial guaranty franchise."

Pursuant to a previously executed investment agreement (the "Investment Agreement"), the WL Ross Funds purchased an aggregate of 10,651,896 common shares of Assured on April 8, 2008. Following this purchase, the WL Ross Funds beneficially owned approximately 13.4% of the Company's outstanding common shares. Any new common shares purchased will be subject to the voting limitations and transfer restrictions contained in the Investment Agreement. The WL Ross Funds are also subject to a standstill provision restricting their ability to acquire additional common shares of the Company. As noted above, this standstill provision was waived in order to permit the WL Ross Funds to purchase up to 5,000,000 additional shares.

Assured has also been advised by WL Ross that it or one or more of its affiliated private equity partnerships may at various times during 2008 and 2009 enter into transactions that provide risk protection to the counterparty in the form of credit default swaps ("CDS") with respect to credit exposures of certain bonds insured by a subsidiary of Assured. The timing and terms of any such transactions are in the sole discretion of WL Ross or its affiliated private equity partnerships and they are not obligated to enter into any such transactions. WL Ross has also advised the Company that they have adopted procedures intended to ensure that each CDS transaction is entered into in accordance with applicable securities laws and regulations and to avoid entering into any CDS transactions on the basis of material non-public information with respect to Assured.
