modeling, forward-looking statements and potential transaction
plans and terms should not be regarded as a representation by

that the marketing and commercialization of Contrave/Mysimba will

misleading public claims about Orexigen; our ability to maintain
sufficient capital to fund our operations for the foreseeable
future; the potential for a Delaware court to determine that one
or more of the patents are not valid or that Actavis proposed
generic product is not infringing each of the patents at issue;
and other risks described in Orexigens filings with the
