                             SECURITIES LAW LEGENDS

This presentation contains forward-looking statements, within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended, that involve a
number of known and unknown risks and uncertainties. These statements are only
predictions and actual events or results in future periods may differ materially
from what is currently anticipated. In particular, Endorex cannot assure you
that it will be able to successfully develop or commercialize products based on
Endorex's technology, particularly in light of the significant uncertainty
inherent in developing drug delivery products, conducting clinical trials and
obtaining regulatory approvals, that Endorex's technologies will prove to be
safe and effective, that Endorex's cash expenditures will be at projected
levels, that Endorex will be able to obtain future financing or funds, that
Endorex or its joint ventures or its collaborations with other companies in the
U.S. and abroad will successfully develop products or become profitable, that
Endorex's joint ventures or its collaborations with other companies will
continue, that Endorex's business strategy will be successful or that Endorex
will be able to carry out our plans for 2001 and beyond. This presentation also
contains forward-looking statements regarding Endorex's, Corporate Technology
Development, Inc.'s, or CTD, and the combined companies' plans, expectations,
intentions and strategies. These statements include forward-looking statements
about Endorex's, CTD's and the combined companies' products, product development
and product pipeline. These statements are not guarantees of future performance
or results and actual results could differ materially from current expectations.
Factors that could cause or contribute to such differences include, but are not
limited to, product integration risk, the possibility that the operations and
management of Endorex and CTD will not be successfully integrated, the
possibility that the merger might not be consummated, the effects of the public
announcement on the progress of certain drug development projects and that
benefits sought to be achieved by the transaction will not be achieved.
Furthermore, Endorex, CTD, and the combined companies cannot assure you that
they will be able to successfully develop or commercialize products based on
their technology, particularly in light of the significant uncertainty inherent
in developing drug and drug delivery products, conducting clinical trials and
obtaining regulatory approvals, that their technologies will prove to be safe
and effective, that their cash expenditures will be at projected levels, that
product development and commercialization efforts will not be reduced or
discontinued due to difficulties or delays in clinical trials or due to lack of
progress or positive results from research and development efforts, that they
will be able to successfully patent, register or protect their technology,
trademarks and products, or that the business strategies of Endorex, CTD, or the
combined companies will be successful. In addition to the matters described in
this presentation, risk factors as described from time to time in Endorex's
filings with the Securities and Exchange Commission, including, but not limited
to, our most recent reports on Form 10-QSB, Form 10-KSB, as amended, and our
Registration Statement on Form S-3, as amended, may affect our financial
results. We assume no obligation to update the information in this release.

Inc. and certain affiliates and employees of Paramount Capital, Inc. may be paid
to solicit proxies in connection with the merger and may have direct or indirect
interests in the merger due to their securities holdings of Endorex and CTD. In

by Endorex and will benefit from insurance coverage for liabilities that may
arise from their service as directors and officers of CTD prior to the merger.
