Cornwall CapitalManagement LP believes CanyonCapital Advisors LLC should end its proxy campaign against Ambac Financial Group Inc.

The election of Cornwall Capital partner Ian Haft to Ambac'sboard on March 28, alongwith the voting and support agreements signed by a number of activist shareholdersthat day, showed Ambac's responsiveness to shareholder concerns, Cornwall Capitalsaid.
