Forward Looking Statements
Forward Looking Statements
Certain statements in this presentation may constitute forward looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995. Although Tengion believes that
these statements are based upon reasonable assumptions within the bounds of its knowledge of
its business and operations, there are a number of factors that may cause actual results to differ
from these statements.
For instance there can be no assurance that: (i) the Company will be able to obtain the capital it
needs to develop its product candidates or continue as a going concern; (ii) the Company will be
able to successfully enroll patients in its clinical trials, including its Phase I clinical trial for the
Neo-Urinary Conduit; (iii) patients enrolled in the Company’s clinical trials will not experience
adverse events related to the Company’s product candidates, which could delay clinical trials or
cause the Company to terminate the development of a product candidate; (iv) the results of the
clinical trial for the Neo-Urinary Conduit will support further development of that product
candidate; (v) data from the Company’s ongoing preclinical studies will continue to be
supportive of advancing its preclinical product candidates; and (vi) the Company will be able to
progress its product candidates that are undergoing preclinical testing, including the Neo-
Kidney Augment, into clinical trials.
For additional factors which could cause actual results to differ from expectations, reference is
made to the reports filed by the Company with the Securities and Exchange Commission under
the Securities Exchange Act of 1934, as amended. The forward looking statements in this
presentation are made only as of the date hereof and the Company disclaims any intention or
responsibility for updating predictions or expectations in this presentation.

Conduit Commercial Assessment
Summary
Most of the 24,000 US / EU annual conduit procedures are for bladder cancer
Market uptake driven by elimination of bowel surgery
 § Market research with urologists is unambiguous
 § Potential for acute and chronic benefits
 § Potential for new standard of care by eliminating the use of bowel tissue
Intend to model offsets based on clinical trial experience including:
 § Length of OR procedure and hospital stay
 § Peri-op, post-op and long-term complications
 § Impact on QoL and activities of daily living
Payer preference for new products with narrow populations and well-defined
needs, strong clinical support and some direct costs offset
