EMISPHERE TECHNOLOGIES ANNOUNCES 2004 SECOND QUARTER RESULTS

Tarrytown, NY - August 4, 2004 --- Emisphere Technologies, Inc. (NASDAQ: EMIS)
today announced results for the second quarter ended June 30, 2004. The Company
also highlighted its progress in development programs using its proprietary
eligen(R) drug delivery technology.

Emisphere reported a net loss of $8.8 million, or $0.48 per share, for the
quarter ended June 30, 2004, as compared to a net loss of $11.4 million, or
$0.63 per share for the quarter ended June 30, 2003.

Total operating expenses were $7.7 million for the 2004 second quarter, a
decrease of $3.0 million, or 28%, compared to the same period last year. Total
operating expenses include research and development costs of $3.7 million, a
decrease of $1.7 million or 31%, compared to last year's second quarter. General
and administrative expenses were $2.8 million, essentially equal to general and
administrative expenses for the same period last year.

Depreciation and amortization expenses were lower in the second quarter than
last year due to the surrender of a portion of the leased space at the Tarrytown
facility and the resultant reduction in the cost basis of leasehold
improvements.

For the quarter ended June 30, 2004, other expense, which includes investment
income, interest expense and loss on sale of fixed assets, was $1.2 million
compared to $0.9 million for the same period last year.

Weighted average shares outstanding for the quarter ended June 30, 2004 and June
30, 2003, were 18.4 million and 18.0 million, respectively.

As of June 30, 2004, Emisphere held cash, cash equivalents and investments
totaling $30.2 million.



Emisphere filed a shelf registration with the Securities and Exchange Commission
on July 8, 2004, to sell in one or more offerings up to five million shares of
its common stock. The Company plans to use the proceeds from the shelf offering
for general corporate purposes, including further development of its lead
clinical programs.

Michael M. Goldberg, M.D., Chairman and Chief Executive Officer of Emisphere
Technologies, Inc., commented, "We made significant progress during the second
quarter in our research and development efforts, both internally and in
collaboration with our partners. Our heparin program has advanced, and we are
now preparing to initiate discussions with the U.S. Food and Drug Administration
(FDA) for a new pivotal clinical trial comparing our soft gelatin capsule
formulation with the current injectable treatment. In addition, other research
programs we have undertaken, both with and without potential partners, have led
to licensing discussions and new relationships with other major pharmaceutical
companies. We consider these ongoing discussions and interest as validation of
our proprietary eligen(R) technology."

PRODUCT DEVELOPMENT UPDATE FOR SECOND QUARTER 2004

Oral Heparin

During the second quarter, Emisphere initiated a clinical trial in the United
States as part of its oral heparin program, with the purpose of selecting an
oral solid formulation of unfractionated heparin (UFH), an
antithrombotic/anticoagulant, for use in late-stage clinical trials. In a
separate release issued today, the Company announced that it has selected a soft
gelatin capsule formulation from the aforementioned trial to move forward into
broad clinical testing. With this formulation, Emisphere plans to initiate
discussions with the U.S. Food and Drug Administration (FDA) to outline an
aggressive clinical development program, comparing the selected formulation with
the currently marketed injectable low molecular weight heparin product.

Oral Insulin

On June 5th, Emisphere presented the results from a multiple-dose clinical study
of an oral insulin tablet using its eligen(R) technology at the 64th Scientific
Sessions of the American Diabetes Association. The study was conducted at PROFIL
institute, an internationally recognized diabetes research center in Germany.
The results from this study indicated that treatment with Emisphere's oral
insulin over a fourteen day period was well-tolerated, led to improvements in
post-prandial blood glucose concentrations and tended to improve fasting blood
glucose concentrations and insulin resistance with no hypoglycemic events, an
adverse complication that is often associated with injected insulin and other
anti-diabetic treatments. Emisphere continues discussions with several potential
partners for its oral insulin program while simultaneously continuing to advance
the program's development.

THE ELIGEN(R) TECHNOLOGY

Emisphere's broad-based oral drug delivery technology platform, known as the
eligen(R) technology, is based on the use of proprietary, synthetic chemical
compounds, known as EMISPHERE(R) delivery agents, or "carriers". These molecules
facilitate or enable the transport

                                        2


of the therapeutic macromolecules across biological membranes such as those of
the gastrointestinal tract, and exert their desired pharmacological effect.
Emisphere's eligen(R) technology makes it possible to orally deliver a
therapeutic molecule without altering its chemical form or biological integrity.

ABOUT EMISPHERE TECHNOLOGIES, INC.

Emisphere Technologies, Inc. (Nasdaq: EMIS) is a biopharmaceutical company
pioneering the oral delivery of otherwise injectable drugs. Emisphere's business
strategy is to develop oral forms of injectable drugs, either alone or with
