Orexigen cautions you that statements included in this report
that are not a description of historical facts are
forward-looking statements. Words such as believes, anticipates,
plans, expects, indicates, will, should, intends, potential,
suggests, assuming, designed and similar expressions are intended
to identify forward-looking statements. These statements are
based on Orexigens current beliefs and expectations. These
forward-looking statements include statements regarding: the
potential success of marketing and commercialization of Contrave
in the United States, including the recently-launched
patient-focused marketing campaign; the potential for Contrave
and Mysimba to achieve commercial success globally; the potential
for Orexigen and its partners to obtain regulatory approvals for
Contrave and Mysimba in additional markets outside the United
States; the potential for Orexigen to achieve commercial success
for Contrave in the United States without a partner; the sales
force capacity, effectiveness and efficiency for
commercialization of Contrave in the United States; the Companys
strategic plans and initiatives; Orexigens ability to manage its
expenses, including by implementing a CVOT that achieves
significant cost savings; the potential to acquire, develop and
market additional product candidates or approved products; and
Orexigens preclinical development plans and ability to perform
IND-enabling studies successfully. The inclusion of financial
modeling, forward-looking statements and potential transaction
plans and terms should not be regarded as a representation by
Orexigen that any of its plans will be achieved. Actual results
may differ materially from those expressed or implied in this
presentation due to the risk and uncertainties inherent in the
Orexigen business, including, without limitation: the potential
that the marketing and commercialization of Contrave/Mysimba will
not be successful, particularly, with respect to Contrave, in the
U.S. following the launch of the patient-focused marketing
campaign; the Companys ability to obtain and maintain
partnerships and marketing authorization globally; our ability to
adequately inform consumers about Contrave; our ability to
successfully commercialize Contrave with a specialty sales force
in the United States; our ability to successfully complete the
post-marketing requirement studies for Contrave; the capabilities
and performance of various third parties on which we rely for a
number of activities related to the manufacture, development and
commercialization of Contrave/Mysimba; the therapeutic and
commercial value of Contrave/Mysimba; competition in the global
obesity market, particularly from existing and generic therapies;
the Companys failure to successfully acquire, develop and market
additional product candidates or approved products; our ability
to obtain and maintain global intellectual property protection
for Contrave and Mysimba; legal or regulatory proceedings against
Orexigen, as well as potential reputational

harm, as a result of 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 Securities and Exchange Commission. You are cautioned
not to place undue reliance on these forward-looking statements,
which speak only as of the date hereof, and Orexigen undertakes
no obligation to revise or update this news release to reflect
events or circumstances after the date hereof. Further
information regarding these and other risks is included under the
heading Risk Factors in Orexigens Quarterly Report on Form 10-Q
filed with the Securities and Exchange Commission on November7,
