                                 SUMMARY
                                 -------

                WHAT INVESTORS SHOULD KNOW ABOUT ENTROPIN
                -----------------------------------------
      (JANUARY 16, 2002 WEBCAST CONFERENCE CALL SUMMARY AND UPDATE)
                            FEBRUARY 25, 2002

WHAT DO WE KNOW ABOUT ENTROPIN'S FIRST GENERATION DRUG, ESTEROM(R)?
Esterom(R) is a revolutionary new topical pharmaceutical product that is
currently being tested in Phase II/III clinical trials.  This study is
examining patients between the ages of 18 and 65 years who have a soft
tissue affliction resulting in impaired function of the shoulder.  In a
Phase II study, it was demonstrated that Esterom(R) provided statistically
significant improvement for soft tissue afflictions for both shoulders and
lower back.

It is management's opinion that Esterom(R) has the potential to replace
other current therapeutics for treating impaired physical function
resulting from soft tissue injuries and diseases - such as tendonitis,
impingement syndrome, bursitis and lower back sprain, and possibly, forms
of arthritis.  Esterom(R) is Entropin's (ETOP) investigational drug for
patients suffering from these painful and limiting range of motion medical
conditions.

Management believes that Esterom(R):
     *    is a topical solution applied directly to the injury and/or
          diseased site providing quick relief  (Results of our Phase II
          clinical study.)
     *    is safe (no significant adverse side effects observed in over 300
          patients)
     *    is fast acting (Esterom(R) demonstrated statistical significant
          effectiveness within 10 minutes of application - Phase II
          results.)
     *    is an analgesic with potential for providing long term pain
          relief (This is the result of animal research by Dr. Gary
          Strichartz, Professor at Harvard Medical School.)
     *    is manufactured by a simple and inexpensive one step process
     *    is protected by the strongest form of patents (composition-
          of-matter patents) in the US and selected foreign countries

WHY INVEST IN ENTROPIN?
Below are some valuable points of interest for past, present, and future
investors' consideration.  These points are expanded in the sections
following this summary.
     *    Entropin has built an exceptional and strong management, Board of
          Directors, and medical advisory team given the Company's size and
          stage of development.  It is a team with integrity, expertise,
          and experience.

                                    2

     *    Entropin's Board of Directors has made the decision NOT to
          develop Entropin as a fully integrated pharmaceutical company.
          Management has been authorized to seek a corporate partner for
          licensing the technology and acquiring or merging the company.
          If in the future the shareholder may receive greater benefit from
          another corporate strategy, the Board may reconsider this
          decision.
     *    Esterom(R) is a fast acting, unique analgesic investigational
          drug with no significant adverse side effects.  Management thinks
          that Esterom(R) has the potential to replace other current
          therapeutics for treating impaired physical function resulting
          from soft tissue injuries and diseases - such as tendonitis,
          impingement syndrome, bursitis and lower back sprain, and
          possibly, forms of arthritis.
     *    Independent laboratory research studies in animals have confirmed
          the potency of Esterom(R) adding intrinsic value and credibility
          for shareholders and negotiating value when dealing with
          potential corporate partners.
     *    The Esterom(R) market is currently served by products that may
          provide relief, but often have significant side effects.  In
          spite of the known side effects, sales in this market are
          estimated to be $4.8 billion per year.  A major market plus is
          that Esterom(R) could address the aches, pains, and joint
          restrictions of growing old.  A great market opportunity for
          Esterom(R) is the growing number of senior citizens, estimated to
          double over the next 25 years.
     *    Management is dedicated to securing U.S. Food and Drug
          Administration (FDA) approval for Esterom(R) in the shortest
          period of time, at the least cost, and with the lowest amount of
          shareholder dilution.
     *    The composition-of-matter patents in the US and foreign countries
          provide the strongest protection possible.  A new patent has been
          filed and several others are being developed to further extend
          the longevity of protection and add value for the shareholder's
          benefit.
     *    Entropin's scientific knowledge of the Esterom(R) solution
          provides a technology platform for the development of additional
          drugs.  Entropin is no longer a one-product company.
     *    Esterom(R) is manufactured in a straightforward inexpensive one
          step process; thereby, providing the potential to increasing
          profit for Entropin and its shareholders and/or a corporate
          partner. (Increased profit potential equates to greater value for
          shareholders.)

WHAT PROGRESS IS BEING MADE IN THE PHASE II/III CLINICAL TRIALS?
The Phase II/III clinical study is proceeding on schedule.  Entropin is
achieving success in its efforts to increase the number of patients in
Phase II/III clinical trials.  Entropin has added four new study sites to
the four already on board.  The new clinics, include Renstar Medical
Research sites in Ocala and Plantation, Florida and Physicians Research
Network sites in Farmington and Hartford, Connecticut.  These additional
sites  bring the total number of clinical sites to eight.  Staff hired by
Entropin monitors each of the sites daily.  Radio and newspaper
advertising, toll free numbers, and a website targeting people with
shoulder pain are proving to be very effective in attracting patients into
the Phase II/III study.

WHAT MAKES ESTEROM(R) WORK AND HOW IS THE TECHNOLOGY PROTECTED?
Esterom(R) is derived from pharmaceutical grade cocaine,
benzolymethylecgonine (BME). When BME is mixed with propylene glycol and
heated, Entropin's proprietary manufacturing process

                                    3

results in the formation of a series of new compounds.  Each of these
compounds has a corresponding hydroxypropyl ester.  The Company has
discovered that the most active molecules in Esterom(R) are the
hydroxyproply esters of benzoylecgonine (BE esters).

The BE esters are new molecular entities and have been patented by Entropin
in the United States.  The Company also holds 38 foreign country patents.
The patents are composition-of-matter patents that provide the strongest
intellectual property protection possible.  A new patent application has
just been filed and, if approved, it will extend protection to 2020.  Other
patents are being prepared.

Dr. Gary Strichartz's animal research has shown that Esterom's(R) mechanism
of action (MOA) is such that the drug effectively blocks nerve impulse
conduction and has long-lasting analgesic, pain inhibitor, properties.
According to Dr. Strichartz, Esterom(R) is five times more potent than
lidocaine, a popular anesthetic.  (Dr. Strichartz is Professor of
Anesthesia and Director of the Anesthesia Research Laboratories at Harvard
Medical School and a world expert on analgesia, pain and pain control.)

When BME is broken down into its various compounds, using Entropin's
hydrolytic process, the resulting compounds do not pass the blood brain
barrier; therefore, Esterom(R) does not appear to be abusive or addictive.

Additional laboratory research is underway and being planned at Harvard and
the University of Kansas to further characterize the MOA of Esterom(R) and
its efficacy.

IS ENTROPIN A ONE-PRODUCT COMPANY?
Entropin has the potential for developing its technology platform and
expanding its product line.  The first generation drug is Esterom(R), a
topical solution used to treat soft tissue injuries and/or diseases.  A
potential second generation of Esterom(R) is a topical lotion or cream that
will be easier to apply, but just as effective as the original formulation.
Furthermore, the active esters form a scientific platform for the
development of additional generation drugs.

Entropin also has a covalent patent in which several of the components of
Esterom(R) have been chemically coupled with other popular drugs such as
aspirin, acetaminophen, ibuprofen, naproxen, etc.  The efficacy of these
new compounds will be explored in future clinical trials.

WHAT IS ENTROPIN'S FUTURE?
The Board of Directors has decided that Entropin will not strive to become
a fully integrated pharmaceutical company.  Management has been directed to
seek a corporate partnership with a major pharmaceutical company.  The
Board's decision may be reconsidered if in the future the shareholders may
receive greater benefit from another corporate strategy.

The outcome of corporate partnering could be one or a combination of the
following:

     1.   Technology and licensing agreement between Entropin and a
          corporate partner.

                                    4

     2.   Acquisition or merger of Entropin by or with a high caliber major
          pharmaceutical company to maximize the value of Entropin's
          technology.

An example of a possible combination of the above might be a licensing
agreement with a first right of refusal for a buy out or merger under
predetermined conditions.

Entropin has two primary goals: (1) developing Esterom(R) to help those who
suffer from soft tissue injuries and diseases and (2) MAXIMIZING
SHAREHOLDER RETURN.  Management will work to maximize shareholder financial
benefit when negotiating with a corporate partner.

HAVE MAJOR PHARMACEUTICAL COMPANIES EXPRESSED INTEREST IN ENTROPIN AND ITS
TECHNOLOGY?
The answer is yes.  Over 40 pharmaceutical companies have been contacted.
A number of these have expressed an interest in partnering with Entropin
and have met with Entropin's management.   Serious negotiations with these
companies will probably begin after the completion of the Phase II/III
clinical trial and will consider a number of criteria including market
potential, product mix, technology platform, corporate culture and deal
structure.  The current research expanding Esterom's(R) scientific base,
including further understanding of its mechanism of action, applications to
other indications, and developments in the manufacturing process, provide
added value in negotiations with prospective corporate partners.

IS ENTROPIN ADEQUATELY FINANCED?
Entropin is adequately financed to complete Phase II/III and the detail
planning of Phase III.  Given the anticipated success of the current Phase
II/III trial and the advances in expanding the science of the Esterom(R)
technology, management is confident that funding will be available as
required.

With the success of Phase II/III and the advances in the technology, it is
expected that one of the interested corporate partners will become a long-
term partner.  A licensing agreement is our FIRST choice of financing and
should provide the required funding for securing approval of Esterom(R)
without additional stock dilution.  Licensing is a common source of funding
for a company of Entropin's size and product development stage.  It is
advantageous that members of the management team have experience in
negotiating partnering contracts.

Management has also considered other financial sources.  These are listed
below in priority order:

     SECOND, Entropin's outstanding warrants could raise an additional $24
     million assuming the stock price allows the warrants to be exercised.

     THIRD, management has had promising discussions with private sources
     for equity lines of credit (PIPES).  With this option, shareholder
     dilution occurs only by the amount of funds used.

                                    5

     FOURTH, although the least desirable option, the Company could go to
     the public market with the possibility of drawing on funds in tranches
     to minimize shareholder dilution.

The Company continues its practice of spending shareholders' money
prudently and wisely. TO ILLUSTRATE, SINCE ENTROPIN'S INCEPTION IN AUGUST
OF 1984, WE HAVE SPENT APPROXIMATELY $11 MILLION ON RESEARCH AND
DEVELOPMENT.  AS OF DECEMBER 31, 2001, WE HAVE $8.7 MILLION IN CASH AND
SHORT-TERM INVESTMENTS. Provided that our Phase II/III clinical trial,
Phase III clinical trial and New Drug Application phase are successful and
within the time frame projected by management, we estimate that our total
cost of developing Esterom(R) for market will be under $50 million
including the funds we have already expended plus our cash on hand. This
compares to the average cost of developing a new prescription drug that is
$802 million according to Tufts Center for the Study of Drug Development.
As you can see, your company, Entropin, will spend only a fraction of the
average cost expended by other pharmaceutical companies.
