                           PROSPECTUS SUMMARY

     This summary highlights selected information that we present more
fully in other sections of this prospectus.  To understand this offering,
you should read the entire prospectus carefully, including the risk factors
and financial statements.

                                ENTROPIN

     Entropin, is a development stage pharmaceutical company that has
developed Esterom(R) solution, a topical formulation for the treatment of
conditions involving impaired range of motion.  Impaired range of motion
often accompanies injuries and disorders of the shoulder and lower back, as
well as other conditions of the joints.  Esterom(R) solution is derived
from a process involving the chemical breakdown of cocaine into new and
different molecules, three of which have been patented by us.   We have
completed four preclinical animal studies and Phase I and Phase II human
clinical trials for Esterom(R) solution. These trials indicated that
Esterom(R) solution was well tolerated at the dose used. Moreover, the
range of motion with patients suffering from shoulder and back conditions
was improved significantly when compared with patients receiving a placebo.
The trials also indicated that Esterom(R) solution did not appear to have
any potential for addiction or abuse.  We began Phase III trials for
treatment of impaired range of motion due to shoulder injuries and
functionality in November 1999.  We expect to complete our Phase III trials
and submit a new drug application to the FDA in early 2001.


OUR MARKET OPPORTUNITY

     If we obtain FDA approval, we believe that there will be a substantial
market for Esterom(R) solution based on the following:

*    40 million Americans suffer from lower back conditions, according to
     a 1999 report by the American Academy of Orthopedic Surgeons.

*    Over 7 million Americans suffer from shoulder injuries or disorders,
     according to a 1996 report by the Center for Disease Control, National
     Center for Health Statistics.

*    Nearly 17.5 million Americans seek prescriptive drug therapy annually
     for the treatment of painful shoulder, acute back strain or related
     conditions, according to the National Ambulatory Medical Care Survey
     1998 report by the National Center for Health Statistics.

*    In its most recent report on lower back pain issued in 1994, the U.S.
     Agency for Health Care Policy and Research indicated that back pain
     was the second most common reason, after the common cold, for seeing
     a doctor and costs associated with back pain, including lost
     productivity, exceeded  $50 billion a year.

*    Treatments for impaired range of motion for lower back and shoulder
     conditions include steroidal drugs, non-steroidal anti-inflammatory
     drugs such as ibuprofen and muscle relaxants, all of which reduce pain
     but do not necessarily improve impaired range of motion.

                                    1
<PAGE>
OUR STRATEGY

     Our initial goal is to complete the commercialization of Esterom(R)
solution.  If we succeed, we will seek to develop products for related
muscle and joint disorders.  In order to achieve our goals, we plan to:

*    Seek FDA approval to market Esterom(R) solution for the treatment of
     impaired range of motion associated with shoulder function;

*    Seek FDA approval to market Esterom(R) solution for the treatment of
     impaired range of motion associated with lower back sprain;

*    Identify and develop other related medical applications for Esterom(R)
     solution, such as the treatment of arthritis and other joint disorders;

*    Identify and develop international markets; and

*    Minimize our fixed costs by outsourcing clinical studies, regulatory
     activities, manufacturing and sales and marketing.


     Entropin is a Colorado corporation. Our corporate offices are located
at 45926 Oasis Street, Indio, California 92201, telephone number (760)

                              one warrant.  The common stock and warrants
                              will trade separately immediately after the

                              redeem the warrants for at least one year
                              after the date of this prospectus.  After
                              that date, if the closing bid price of our
                              common stock on each of the 10 consecutive
                              trading days preceding our notice of
                              redemption is greater than or equal to
                              $_____ (200% of the closing bid price of our
                              common stock on the effective date of the
                              offering), we may redeem some or all of the

                              redemption price will be $0.25 per warrant.
                              If we give notice of redemption, holders of
                              the warrants will have 30 days during which
                              they may elect to exercise the warrants,
                              sell the warrants or allow the warrants to
                              be redeemed for the redemption price.

                              outstanding.  Shares outstanding exclude up
                              to 3,851,682 shares of common stock issuable
                              on exercise of outstanding options, warrants
                              and convertible securities.


Risk Factors. . . . . . . .   An investment in the shares and warrants
                              involves a high degree of risk.  You should
                              not consider purchase of the shares and
                              warrants  unless you can afford to lose your
                              entire investment.

Use of proceeds . . . . . .   To fund costs associated with Phase III
                              clinical trials; the FDA approval process
                              for Esterom(R) solution; research and
                              development of additional applications of
                              Esterom(R) solution; general and
                              administrative expenses; and working capital.

                              RISK FACTORS

     The offering involves a high degree of risk.  You should carefully
consider the risks and uncertainties of this offering described below and
other information in this prospectus before investing in our common stock.
If any of these risks occur, our business, results of operation and
financial condition could be adversely affected.  This could cause the
trading price of our common stock to decline, and you might lose part or
all of your investment.

     Many of the statements in this prospectus constitute forward-looking
statements.  These statements involve known and unknown risks,
uncertainties, and other factors that may cause our results, levels of
activity, performance or achievements to be materially different from those
implied by these forward-looking statements.  In some cases, you can
identify forward-looking statements by terminology such as "may," "will,"
"should," "expects," "plans," "anticipates," "believes," "estimates,"
"predicts," "potential," "continue" or the negative of these terms or other
comparable terminology.

     Although we believe that the expectations reflected in the forward-
looking statements are reasonable, we cannot guarantee future results,
levels of activity, performance or achievements.  Moreover, neither we nor
any other person assumes responsibility for the accuracy and completeness
of these statements.  We are under no duty to update any of the forward-
looking statements after the date of this prospectus.


WE HAVE A LIMITED OPERATING HISTORY, A HISTORY OF LOSSES AND EXPECT FUTURE
LOSSES.

     We have no operating history upon which an investor can base an
evaluation of our company and our prospects.  Our auditor's report for year
end December 31, 1999 expressed doubt about our ability to continue as a
going concern.  We have had losses from operations since our inception in
1984 to December 31, 1999, totaling $12,518,064, and we expect to incur
future losses from operations.  At December 31, 1999 we had a total
stockholders deficit of $1,985,313.  We expect our operating expenses to
significantly increase over the next several years due to clinical testing
and other expenses related to seeking FDA approval.  Our ability to achieve
profitable operations is dependent on obtaining regulatory approval for
Esterom(R) solution, entering into agreements for product development and
commercialization, and expanding from development into successful
marketing, all of which require significant amounts of capital.  See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" beginning on page 14 and "Use of Proceeds" on page  10.



WE ARE DEPENDENT ON THE PROCEEDS OF THIS OFFERING AND MAY REQUIRE
ADDITIONAL CAPITAL.

     We have financed our business through the sale of securities and
advances from stockholders and have had no revenue from operations.  We are
dependent upon the proceeds of this offering to fund continuing operations
and management has broad discretion as to the application of the proceeds.
We may require additional capital to fund our operations.


                                    5
<PAGE>
WE WILL NOT BE ABLE TO MARKET ESTEROM(R) SOLUTION UNLESS WE OBTAIN REQUIRED
REGULATORY APPROVAL.

     The FDA approval process generally takes years and consumes
substantial capital resources with no assurance of ultimate success.  We
cannot apply for FDA approval to market Esterom(R) solution until the
product successfully completes the required Phase III clinical trials.
Several factors may prevent our  successful completion of the Phase III
clinical trials including:

     *    insufficient capital resources;
     *    inability to obtain the required number of patients to complete
          the trials; and,
     *    insufficient proof that Esterom(R) solution is safe and
          effective.


     The regulatory approval processes differ among foreign jurisdictions
and approval in one jurisdiction does not ensure other approvals.  As a
result, we may be required to undertake additional trials and incur
additional expense in order to obtain foreign approvals.  Even if we
complete the trials, we may be unable to obtain FDA approval of Esterom(R)
solution. Failure to obtain FDA or foreign jurisdictional approval would
negatively impact our business.  See "Our Business - Government Regulation"
beginning on page 19.


IF WE LOSE OUR ESTEROM(R) SOLUTION MANUFACTURER, WE WILL BE UNABLE TO BRING
ESTEROM(R) SOLUTION TO MARKET.


     We are dependent upon Mallinckrodt, Inc., our sole supplier, to
provide us with cocaine as a raw material from which the active ingredients
in Esterom(R) solution are derived.  If Mallinckrodt is unable or unwilling
to supply us, we may be unable to bring Esterom(R) solution to market.  See
"Our Business - Outsourcing" on page 18.



OUR SUCCESS DEPENDS UPON ESTEROM(R) SOLUTION'S ACCEPTANCE BY PHYSICIANS,
INSURANCE COMPANIES AND THE PUBLIC.

     Sales of Esterom(R)'s solution depend on acceptance of the product by
physicians, insurance companies who provide pharmaceutical coverage and the
public as an alternative to, or in combination with, other therapies for
the treatment of impaired range of motion associated with painful shoulder
and other conditions.


ESTEROM(R) SOLUTION'S CLASSIFICATION AS A CONTROLLED SUBSTANCE MAY LIMIT
SALES AND INCREASE COSTS.


     As a controlled substance, Esterom(R) solution will be subject to
expensive and burdensome administrative requirements which will increase
our costs.  Moreover, these administrative requirements may discourage
Esterom(R) solution's use and acceptance by the medical community.  See
"Our Business - DEA Status" on page 21.


WE WILL BE DEPENDENT UPON THIRD PARTIES TO MARKET ESTEROM(R) SOLUTION.


     We have no experience in the sale or marketing of pharmaceutical
products and will be dependent upon third parties to sell and market
Esterom(R) solution.  If we are unable to enter into satisfactory marketing
arrangements, our sales will be adversely affected.  See "Our Business -
Outsourcing" on page 18.


                                    6
<PAGE>
IF WE ARE UNABLE TO DEFEND OUR ESTEROM(R) SOLUTION PATENTS OR IF OTHERS
DEVELOP SUBSTANTIALLY EQUIVALENT PRODUCTS, OUR BUSINESS COULD BE IMPACTED.


     Our patents, trademarks and other intellectual property rights are
important to our success.  Patent litigation can be extremely expensive and
time consuming.  If we are unable to defend our existing patents or if
others develop similar products beyond the protection of our existing
patents, our business could be impaired.   See "Our Business - Patents" on
page 19.


WE WILL BE EXPOSED TO PRODUCT LIABILITY CLAIMS.


     We will be exposed to potential product liability claims which are
inherent in the testing, manufacturing, marketing and sale of
pharmaceutical products, and product liability claims may be asserted
against us.  Product liability insurance for the pharmaceutical industry is
expensive.  There can be no assurance that adequate insurance coverage will
be available to us at acceptable costs, or that a product liability claim
would not adversely affect our business or financial condition.    See "Our
Business - Product Liability Insurance" on page 21.



A LARGE NUMBER OF OUR SHARES OF COMMON STOCK ARE ELIGIBLE FOR FUTURE SALE
WHICH COULD LOWER OUR MARKET PRICE.

      Sales of common stock after the offering, or even the potential for
those sales, are likely to lower the market price of our common stock.  In
addition, these sales may negatively affect our ability to raise needed
capital through the sale of our common stock.  The table below indicates
the number of shares outstanding, the number of shares issuable upon
exercise of options, warrants and convertible securities and which of such
shares are free trading and restricted.


     NUMBER OF
     SHARES         DESCRIPTION

     7,382,280      Common stock currently outstanding

     6,028,082      Free trading common stock outstanding

     3,621,182      Common Stock issuable upon exercise of currently
                    outstanding options and warrants

     2,000,000      Common stock issuable upon exercise of warrants
                    outstanding upon completion of offering

       230,500      Common stock issuable upon conversion of Series B
                    convertible preferred stock

     1,354,198      Common stock available for sale under Rule 144 of the
                    Securities Act



     Other than 65,000 shares, all remaining 4,179,564 shares owned by our
directors, officers, and 5% or greater stockholders, and substantially all
of the shares underlying the outstanding options and warrants are subject
to lock-up agreements which expire one year after the date of this
prospectus unless released sooner upon the written consent of the
representatives.  When the lock-up period expires, the 4,179,564 shares
subject to lock-up and the shares issuable upon exercise of options and

                                    7
<PAGE>
warrants, and conversion of preferred stock will be eligible for sale which
will have a depressive effect on the market price of our common stock.  See
"Shares Eligible for Future Sale" on page 34 and "Description of Securities
- - Other Options, Warrants and Convertible Securities" on page 33.



INVESTORS WILL EXPERIENCE DILUTION OF BOOK VALUE OF SHARES PURCHASED IN THE
OFFERING.

     Net tangible book value per share at December 31, 1999 and prior to
the offering is $(.31) per share.  Upon the sale of 2,000,000 shares of
common stock at $_____ per share, net tangible book value per share after
the offering will be $_____ per share, resulting in dilution of $_____ or
____% to investors in the offering.  Current shareholders purchased their
shares at a price below the price of the shares being offered.



OUR CONTROL WILL NOT CHANGE AFTER THE OFFERING.

     After the completion of this offering, the officers, directors and
other principal shareholders will continue to own a majority of our common
stock, and have voting control over us.


OUR STOCK HAS BEEN THINLY TRADED AND IS SUBJECT TO PRICE VOLATILITY.

     Before this offering, our stock traded on the NASD OTC Bulletin Board.
Historically:

     *    our Company has not been covered by regular reports from
          financial analysts of established standing;

     *    the limited amount and distribution of our stock has exacerbated
          the effect of relatively small imbalances in supply and demand;
          and

     *    the number of stock brokerage firms trading our common stock has
          been limited.

     Due to these factors, the trading price of our common stock could be
subject to wide fluctuations in response to quarterly variations in
operating results, changes in financial estimates by securities analysts,
announcements of technological innovations or new products by us or our
competitors or other factors.  In addition, the stock market has
experienced extreme price and volume fluctuations that have particularly
affected the market prices for many biotechnology and small capitalization
companies.


OUR STOCK AND WARRANTS MAY BECOME SUBJECT TO "PENNY STOCK" RULES.

     If our common stock were to trade for less than $5.00 per share, then
our common stock and warrants would each be considered a "penny stock"
under federal securities law. Additional regulatory requirements apply to
trading of penny stocks by broker-dealers. This could adversely effect the
trading market for our common stock and warrants.


                                    8
<PAGE>
OUR WARRANTS CAN BE REDEEMED ON SHORT NOTICE.


     At any time after one year following the date of this prospectus, we
can redeem the warrants for $0.25 per warrant on 30 days' written notice,
provided that the closing price of our common stock has been at least $___
for the ten consecutive trading days immediately preceding the notice of
redemption.  If we give notice of redemption, a holder would be forced to
sell or exercise the warrants or accept the redemption price.  See
"Description of Securities - Warrants" on page 31.



WE CAN ISSUE PREFERRED STOCK WITHOUT THE CONSENT OF OUR SHAREHOLDERS.

     Our Board of Directors may issue shares of preferred stock without
stockholder approval on such terms as the Board may determine. The rights
of the holders of common stock will be subject to, and may be adversely
affected by, the rights of the holders of any preferred stock that we may
issue in the future.  See "Description of Securities - Preferred Stock" on
page 33.


A CURRENT PROSPECTUS AND STATE BLUE SKY REGISTRATION IS REQUIRED BEFORE
PURCHASERS MAY EXERCISE THE WARRANTS.


     Purchasers of our warrants will be able to exercise the warrants only
if a current prospectus relating to the common stock underlying the
warrants is then in effect, and only if our common stock is qualified for
sale or exempt from qualification under applicable state securities laws of
the states in which the holders of the warrants reside.  Although we have
undertaken to maintain the effectiveness of a current prospectus covering
the common stock underlying the warrants, there can be no assurance that we
will be able to do so.  The value of the warrants may be impaired if a
current prospectus covering the common stock issuable upon exercise of the
warrants is not kept effective, or if the common stock is not qualified or
exempt from qualification in the states in which the holders of warrants
reside.  See "Description of Securities - Warrants" on page 31.



WE HAVE NO AGREEMENTS WITH OUR MANAGEMENT WHICH SECURE THEIR CONTINUING
SERVICE.

     Our management members are employed at will.  Therefore, a management
member may terminate employment at any time.  See "Management" beginning on
page 23.



WE ENTERED TRANSACTIONS WITH RELATED PARTIES WHICH WERE NOT SUBJECT TO
INDEPENDENT DIRECTOR APPROVAL.

     Past transactions with related parties were ratified by disinterested
directors and believed to be on terms at least as favorable as obtainable
from third parties. However, until recently, we did not have independent
directors. Future related party transactions will be subject to independent
director ratification.  See "Related Party and Other Material Transactions"
beginning on page 30.

<PAGE>
                             USE OF PROCEEDS

     After payment of underwriting commissions and other expenses of the
offering, the net proceeds of the offering are estimated to be $________
million, or $______ million if the over allotment option is exercised.  We
expect to use the net proceeds approximately as follows:


*    Phase III clinical trials                    $              55%

*    New Drug Application for Esterom(R)          $              20%
     solution

*    Research and development of additional
     applications of Esterom(R) solution          $              10%

*    General office and administrative expenses
     and working capital (includes salaries,
     rent, travel, professional fees)             $              15%



     There may be changes in our proposed use of proceeds due to changes in
our business. Proceeds not immediately needed will be invested in treasury
bills, insured bank deposits or similar investments.  No proceeds will be
used to redeem preferred stock.



                             DIVIDEND POLICY


     We have never declared or paid dividends on our common stock and do
not intend to pay dividends on our common stock in the foreseeable future.
Instead, we will retain any earnings to finance the expansion of our
business and for general corporate purposes.  We are obligated to pay
dividends on our Series A and Series B preferred stock, although we may
elect to pay the dividends on the Series B preferred stock in shares of our
common stock.  We have paid no dividends on our Series A preferred stock.
As of December 31, 1999 we have issued 24,550 shares of common stock as
dividends on our Series B preferred stock.

                  MANAGEMENT'S DISCUSSION AND ANALYSIS
            OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW


     We were incorporated in California in 1984 as Entropin, Inc. ("old
Entropin"), and in 1998, completed an agreement and plan of merger with
Vanden Capital Group, Inc. to exchange all of the issued and outstanding
common shares of old Entropin for 5,220,000 shares of Vanden's common
stock. We were merged into Vanden, and Vanden changed its name to Entropin,
Inc.  For accounting purposes, the acquisition was treated as a
recapitalization of old Entropin based upon historical cost, with old
Entropin as the acquirer.  In conjunction with the merger, Entropin, Inc.
became a Colorado corporation.

     From our inception in August 1984, we have devoted our resources
primarily to funding our research and development efforts.  We have been
unprofitable since inception and have had no revenue from the sale of
products or other resources, and do not expect revenue for the next two
years, or until Esterom(R) solution has received FDA approval.  We expect
to continue to incur losses for the foreseeable future through the
completion of our Phase III clinical trials and the new drug application
process.  As of December 31, 1999, our accumulated deficit was
approximately $12.6 million.


PLAN OF OPERATION


     We have raised sufficient funds in 1999 to complete the first part of
a two part Phase III clinical trial program associated with the FDA
approval process for the treatment of acute painful shoulder.  The trials
began in November 1999 and the first part is scheduled for completion in
mid-2000.  We intend to use a substantial portion of the net proceeds of
our secondary offering to fund our Phase III  clinical trials through our
new drug application process related to the treatment of acute painful
shoulder and to provide funds for research and development and  working
capital.  In the future, we plan to seek FDA approval to market Esterom(R)
solution for the treatment of impaired range of motion associated with
lower back pain, and identify and develop other medical applications for
Esterom(R) solution such as applications for arthritis and other joint
disorders.  We intend to minimize our fixed costs by outsourcing clinical
studies, regulatory activities, manufacturing and sales and marketing.  We
have engaged the services of a full-time chief executive officer and
president beginning November 29, 1999 which will increase our general and
administrative expenses.


RESULTS OF OPERATIONS


     Year ended December 31, 1999 compared to year ended December 31, 1998.
Our research and development expenses were $1,743,837 for 1999, as compared
to $906,719 in 1998.  The increase in research and development resulted
primarily from initiation of Phase III clinical trials, and approximately
$200,000 from non-cash compensation expenses associated with stock options
granted to Western Center for Clinical Studies (Western).  Our general and
administrative expenses were $3,211,809 in 1999, as compared to $1,844,575
in 1998.  The increase in general and administrative expenses relates
primarily to our preparation costs for the start of Phase III clinical
trials and fund raising activities.  Moreover, the 1999 increase resulted
from an increase of approximately $1,200,000 in non-cash compensation
expense associated with stock options.

                                   14
<PAGE>
     Our interest income was $64,888 in 1999, as compared to $24,738 in
1998.  The increase was primarily a result of larger temporary cash
investment balances in 1999 from proceeds of private placements.


LIQUIDITY AND CAPITAL RESOURCES


     We have financed our operations since inception primarily through the
net proceeds generated from the sale of our common and preferred stock, and
through loans and advances from stockholders that were subsequently
converted into equity securities. From inception through December 31, 1999,
we have received net cash proceeds from financing activities aggregating
approximately $6.8 million from these transactions.  As of December 31,
1999, our working capital was $1,937,721.

     Our liquidity and capital needs relate primarily to working capital,
research and development of Esterom(R) solution, and other general
corporate requirements.  We have not received any cash from operations
since inception.  Based on our current plans, we believe the proceeds from
our secondary offering will provide sufficient capital resources to fund
our operations for at least the next 20 months.  Expectations about our
long-term liquidity may prove inaccurate if approval for Esterom(R)
solution is delayed or not obtained.  We will not generate revenue from
sales of Esterom(R) solution unless Esterom(R) solution is approved by the
FDA for marketing.

     Net cash used in operating activities was approximately $1,480,000 in
1998 and $1,617,000 in 1999.  The cash used in operations was primarily
related to funding expansion of research and development activities as well
as establishing an administrative infrastructure.  For the year ended
December 31, 1999, cash used in operating activities principally represents
the net loss for the period of $4,939,262 adjusted for non-cash stock
option compensation and an increase in accounts payable.

     As of December 31, 1999, our principal source of liquidity was
approximately $2.3 million in cash and cash equivalents.


     In April 1998, we entered into an agreement with Western to assist us
in obtaining FDA approval for Esterom(R) solution. We are required to pay
management fees of approximately $880,400 through January 5, 2001 and
$76,400 per quarter beginning January 2001 and continuing until a new drug
application is filed with the FDA. We also issued to Western stock options
to purchase 450,000 shares of our common stock at $1.50 per share.


     In August 1999, we entered into an agreement with Therapeutic
Management, Inc. to provide us clinical trial management services and
monitor all aspects of Esterom's Phase III A and B clinical studies.  In
November 1999, we entered into an agreement with Western to assume our
obligations under the Therapeutic Management Agreement.  We will pay
Western approximately $350,000 based upon completion of certain project
goals.


     In November 1999, we entered into an agreement with Western to assume
our obligations under our agreement with Therapeutic Management, Inc. to
perform tasks required to comply with FDA regulations applicable to the
conduct, coordination and management of the first Phase III trial.  Among
other things, WCCS is to select investigators, train clinical site
personnel, maintain the master file of

                                   15
<PAGE>
all pre-study and study documents, and prepare the Study Report to be
submitted to the FDA.  We will pay Western approximately $350,000 based on
completion of certain project goals.


     Our operating expenses will increase as we proceed with the two part
Phase III clinical trials through the new drug application and other
related FDA approval process.  We also expect that our general and
administrative expenses will increase significantly with the addition of
our full time chief executive officer and president.  The 20 month period
estimate for which we expect available sources of cash to be sufficient to
meet our funding needs is a forward looking statement that involves risks
and uncertainties as set forth under "Risk Factors" and elsewhere in this
prospectus.  In the event our capital requirements are greater than
estimated, we may need to raise additional capital to fund our research and
development activities.  Our future liquidity and capital funding
requirements will depend on numerous factors, including the timing of
regulatory actions for Esterom(R) solution, the cost and timing of sales,
marketing and manufacturing activities, the extent to which Esterom(R)
solution gains market acceptance, and the impact of competitors' products.
There can be no assurance that such additional capital will be available on
terms acceptable to us, if at all.  If adequate funds are not available, we
may be forced to significantly curtail our operations or to obtain funds
through entering into collaborative agreements or other arrangements that
may be on unfavorable terms.  Our failure to raise capital on favorable
terms could have a material adverse effect on our business, financial
condition or results of operations.


YEAR 2000 ISSUE


     To date we have not experienced any material difficulties or incurred
significant expenditures in connection with Year 2000 issues.  All of our
expenses have related to the opportunity cost of time spent by several of
our employees identifying and evaluating the Year 2000 compliance matters.
The agreements with Western and Therapeutic Management represent that their
software systems are Year 2000 compliant.  We contacted all other major
vendors, suppliers, financial institutions and service providers to ensure
they are Year 2000 compliant.  Key third party vendors provided a statement
in writing that their software or systems are Year 2000 compliant.

                              OUR BUSINESS

     Entropin is a development stage pharmaceutical company that has
developed Esterom(R) solution, a topical formulation for the treatment of
conditions involving impaired range of motion.  Impaired range of motion
often accompanies injuries and disorders of the shoulder and lower back, as
well as other conditions affecting body joints.  Esterom(R) solution is
derived from a process involving the chemical breakdown of cocaine into new
and different molecules, three of which have been patented by us.  We have
completed four preclinical animal studies and Phase I and Phase II human
clinical trials for Esterom(R) solution. These trials indicated that
Esterom(R) solution was well tolerated and did not appear to have any
potential for addiction or abuse.  Moreover, the range of motion with
patients in the Phase II trial suffering from shoulder and lower back
conditions was improved significantly when compared with patients receiving
a placebo.  We began Phase III trials for treatment of impaired range of
motion due to shoulder injuries and functionality  in November 1999.  We
expect to complete our Phase III trials and submit a new drug application
to the FDA in early 2001.

     Esterom(R) solution is derived through a manufacturing process
involving hydrolysis and solvolysis of cocaine in a propylene glycol and
water solution.  Hydrolysis and solvolysis are  chemical processes in which
a substance reacting with a solvent such as propylene glycol and water
solution, is changed into one or more other substances.  Through this
process, we have identified three new molecules, derivatives of
benzoylecgonine, ecgonine and ecgonidine, which form the basis of our
formulation of Esterom(R) solution and are claimed under two of our eight
United States patents.  A third United States patent claims a method for
preparing Esterom(R) solution.

REGULATORY HISTORY

     In March 1987, we filed an investigative new drug application with the
FDA which incorporated the results of our four pre-clinical animal safety
studies in which no significant toxicity was noted.  Our subsequent human
Phase I clinical safety trial for Esterom(R) solution was completed in
1991, and involved 24 healthy male subjects.  The results of this trial
indicated that Esterom(R) solution was well tolerated and showed no
significant toxicity.  Based on these results, the FDA allowed us to
initiate Phase II clinical efficacy and safety trials in 1992.

     Our Phase II clinical trial, completed in 1994, was designed to
determine the safety and  efficacy of Esterom(R) solution in patients who
had impaired range of motion due to acute lower back strain, acute painful
shoulder or the removal of a cast. The Phase II clinical trial involved 97
patients, each of whom received two topical applications of Esterom(R)
solution or placebo, with the second treatment applied 24 hours after the
first.  The results of the trial showed that Esterom(R) solution provided
statistically significant improved range of motion in both back and
shoulder conditions which was sustained for at least seven days.  There was
no clinically observed local anesthetic or analgesic effect.  The range of
motion for each condition was measured by the number of degrees to which
the subject could move the affected part in one direction or another. The
results for patients who had impaired range of motion resulting from cast
removal were inconclusive and we did not pursue this indication further.

     In 1996, we submitted our Phase III Protocol to the FDA, and a revised
Phase III Protocol in 1999.  Our Phase III studies will include two trials
in multiple clinical study centers in differing

                                   17
<PAGE>
geographic areas of the U.S.  The trials will be double-blind and placebo-
controlled in which neither patient nor doctor will know whether the
patient receives Esterom(R) solution or placebo.

     We began the first Phase III trial in November 1999 and we expect to
begin the second trial in several months.  In each of the two studies 300
patients will be enrolled for a total of 600 patients.  Of the 300 patients
in each study, 100 will receive single strength Esterom(R) solution, 100
double strength, and 100 placebo.  The second trial has a longer patient
follow-up period than the first trial.

     Our Phase III trials will test Esterom(R) solution for improved range
of motion and functionality associated solely with shoulder injuries.
Functionality involves a patient's ability to perform everyday functions,
such as hair combing  or removing a pullover sweater.  Subsequently, we
intend to seek FDA approval for treatment by Esterom(R) solution of lower
back sprain.

OUTSOURCING


     In January 1997, we entered into an agreement with Mallinckrodt, Inc.,
the only company authorized by the Drug Enforcement Agency (DEA) to provide
cocaine for medical and research purposes, and to supply and manufacture
Esterom(R) solution.  Due to federal restrictions, Esterom(R) solution
cannot be manufactured outside of the United States for sale in the United
States.  Due to DEA licensing requirements, Mallinckrodt is our sole source
for  cocaine and for producing Esterom(R) solution.  In addition, our
agreement with Mallinckrodt provides that it will comply with the Good
Manufacturing Practices  imposed by the FDA through its facilities
inspection program.  In exchange for the services, Mallinckrodt was granted
the right to be our exclusive supplier in North America and a right of
first refusal to be our exclusive world-wide supplier.


     In April 1998, we entered into an agreement with Western, to assist us
in administering the clinical trials necessary for obtaining FDA approval
of Esterom(R) solution.  Daniel L. Azarnoff, M.D., a director of Entropin,
is a director of Western.

     In August 1999, we entered into an agreement with Therapeutic
Management, Inc., a clinical research organization, to provide
comprehensive clinical trial management and monitor our first of two Phase
III clinical trials for Esterom(R) solution.

     In November 1999, we entered into an agreement with Western to perform
and assume our obligations under our agreement with Therapeutic Management
for compliance with FDA regulations.

     We do not intend to establish our own direct sales force to market
Esterom(R) solution.  Instead, we are actively pursuing strategic
relationships with pharmaceutical companies to whom we can outsource the
marketing of Esterom(R) solution.

                                   18

PATENTS

     We hold eight U. S. patents issued between 1984 and 1998 with
expiration dates ranging from September 2001 to June 2014.  These patents
include two material composition patents covering the molecules contained
in Esterom(R) solution that expire in 2012 and 2013.  Our three initial
patents were based on methods of treatment of rheumatoid arthritis using
benzoylecgonine and related compounds.  Our five subsequent patents include
compound, composition and method claims involving derivatives of the
compounds represented in the earlier patents.  Since the formula for
Esterom(R) solution contains the derivatives protected by certain of the
subsequent patents, the expiration of the earlier patents in 2001 and 2002
will not permit a replication of Esterom(R) solution by a competitor.   We
believe that some of the patents to which we have rights may be eligible
for extensions of up to five years.

     In December 1993 we filed an International Patent Application under
the Patent Cooperation Treaty claiming compounds present in the Esterom(R)
formulation from which eight separate patent applications were derived --
Australia, Canada, Europe, Hungary, Japan, New Zealand, Norway and Poland.
In addition, we have filed patent applications in China, Israel, Mexico,
South Africa and Taiwan.  From these foreign applications, nine patents
have been issued to date.

GOVERNMENT REGULATION

     The research, development, testing, manufacturing, promotion,
marketing and distribution of drug products are extensively regulated by
government authorities in the United States and other countries.  Drugs are
subject to rigorous regulation by the FDA in the United States and similar
regulatory bodies in other countries.  The steps ordinarily required before
a new drug may be marketed in the United States, which are similar to steps
required in most other countries, include:

     *    Preclinical safety studies in animals and formulation studies and
          the submission to the FDA of an Investigational New Drug (IND)
          application for a new drug;

     *    Adequate and well-controlled clinical trials to establish the
          safety and efficacy of the drug for each medical indication;

     *    The submission of a New Drug Application (NDA) to the FDA; and,

     *    FDA review and approval of the NDA.

     Preclinical animal tests include laboratory evaluation of product
chemistry, stability, pharmaceutical properties and formulation, as well as
studies to prove the product is safe in animals.  The results of
preclinical testing are submitted to the FDA as part of an NDA.   The FDA
may halt proposed or ongoing clinical trials until it  allows the trials to
continue under specified terms.

     Clinical trials to support new drug applications are typically
conducted in three sequential phases.  During Phase I safety studies, the
initial introduction of  the drug on healthy human subjects, the drug is
tested to assess how the drug is handled in the body and the level of drugs
in the body over time,  as well as side effects associated with increasing
doses.

                                   19
<PAGE>
     Phase II usually involves studies in a limited patient population to:

     - assess the efficacy of the drug in specific, targeted indications;

     - assess dosage tolerance and optimal dosage; and/or

     - identify possible adverse effects and safety risks.

     If a compound is found to be potentially effective and to have an
acceptable safety profile in Phase II evaluations, Phase III trials (also
called pivotal studies, major studies or advanced clinical trials) are
undertaken to further demonstrate clinical efficacy and to further test for
safety of the  product within an expanded patient population at
geographically dispersed clinical study sites.

     After successful completion of the required clinical testing, a NDA is
generally submitted.  The FDA may request additional information before
accepting a NDA for filing, in which case the application must be
resubmitted with the additional information.  Once the submission has been
accepted for filing, the FDA has 180 days to review the application and
respond to the applicant.  The review process is often significantly
extended by FDA requests for additional information or clarification.  The
FDA may refer the new drug application to an appropriate advisory committee
for review, evaluation and recommendation as to whether the application
should be approved, but the FDA is not bound by the recommendation of an
advisory committee.

     If FDA evaluations of the new drug application and the manufacturing
facilities are favorable, the FDA may issue either an approval letter or an
approvable letter.  An approvable letter will usually contain a number of
conditions that must be met in order to secure final approval of the new
drug application and authorization of commercial marketing of the drug for
certain indications.  The FDA may refuse to approve the new drug
application or issue a not approvable letter, outlining the deficiencies in
the submission and often requiring additional testing or information.

     The manufacturers of approved products and their manufacturing
facilities are subject to continual review and periodic inspections.
Because we intend to contract with third parties for manufacturing our
product, our control of compliance with FDA requirements will be more
complicated.  In addition, identification of certain side effects or the
occurrence of manufacturing problems after any of our drugs are on the
market could cause subsequent withdrawal of approval, reformulation of the
drug, additional clinical trials, and changes in labeling of the product.

     Outside the United States, our ability to market our products will
also be contingent upon receiving marketing authorizations from the
appropriate regulatory authorities.  The foreign regulatory approval
process includes all of the risks associated with the FDA approval set
forth above.  The requirements governing the conduct of clinical trials and
marketing authorization vary widely from country to country.  At present,
foreign marketing authorizations are applied at a national level, although
within Europe procedures are available to companies wishing to market a
product in more than one European Union, or EU, member state.

     Under a new regulatory system in the EU, marketing authorizations may
be submitted at either a centralized, a decentralized or a national level.
The centralized procedure is mandatory for the

                                   20
<PAGE>
approval of biotechnology products and high technology products and
available at the applicant's option for other products.  The centralized
procedure provides for the grant of a single marketing authorization that
is valid in all EU member states.  The decentralized procedure is available
for all medicinal products that are not subject to the centralized
procedure.  The decentralized procedure provides for mutual recognition of
national approval decisions, changes existing procedures for national
approval decisions and establishes procedures for coordinated EU actions on
products, suspensions and withdrawals.  Under this procedure, the holder of
a national marketing authorization for which mutual recognition is sought
may submit an application to one or more EU member states, certify that the
dossier is identical to that on which the first approval was based or
explain any differences and certify that identical dossiers are being
submitted to all member states for which recognition is sought.  Within 90
days of receiving the application and assessment report, each EU member
state must decide whether to recognize approval.  The procedure encourages
member states to work with applicants and other regulatory authorities to
resolve disputes concerning mutual recognition.  Lack of objection of a
given country within 90 days automatically results in approval of the EU
country.

     We will choose the appropriate route of European regulatory filing to
accomplish the most rapid regulatory approvals.  However, the regulatory
strategy may not secure regulatory approvals or approvals of the chosen
product indications.  We intend to contract with an experienced third party
to assist with our European clinical development and regulatory approvals.

DEA STATUS

     The DEA has designated Esterom(R) solution as a Schedule II controlled
substance.  The manufacture, storage, shipment and use of a Schedule II
controlled substance is subject to costly and burdensome regulations.  We
have submitted a petition to the DEA to delist Esterom(R) solution as a
Schedule II substance based on the data obtained in Phase I and II clinical
studies in human beings which indicated that Esterom(R) solution showed no
effects on the cardiovascular system and did not appear to cross the blood-
brain barrier.  The petition is currently under review by the U.S. Attorney
General's office and the FDA.  We do not expect a decision unless and until
Esterom(R) solution is approved for marketing by the FDA.

PRODUCT LIABILITY INSURANCE

     Sales of Esterom(R) solution entails risk of product liability claims.
Medical testing has historically been litigious, and we face financial
exposure to product liability claims in the event that use of Esterom(R)
solution results in personal injury.  We also face the possibility that
defects in the manufacture of Esterom(R) solution might necessitate a
product recall.  There can be no assurance that we will not experience
losses due to product liability claims or recalls in the future.  We
anticipate purchasing product liability insurance in reasonable and
customary amounts when we begin to sell Esterom(R) solution.  Such
insurance can be expensive, difficult to obtain and may not be available in
the future at a reasonable cost or in sufficient amounts to protect us
against losses due to liability.  An inability to maintain insurance at an
acceptable cost or to otherwise protect against potential product liability
could prevent or inhibit our commercialization of Esterom(R) solution.
Moreover, a product liability claim in excess of relevant insurance
coverage or product recall could have a material adverse effect on our
business, financial condition and results of operations.

                                   21

ROYALTY COMMITMENTS


     In connection with our acquisition of the rights to the three original
patents for Esterom(R) solution from non-affiliated parties, we agreed to
pay a royalty of approximately 1% of amounts paid to us from the sale of
Esterom(R) solution.  We have agreed to pay a minimum royalty from actual
sales consisting of a front end payment of $40,000 and quarterly payments
of $3,572 which is  accruing from December 1, 1989, less a credit to us for
50% of patent expenses we incur.


COMPETITION

     To our knowledge, there are no products on the market which treat
impaired range of motion associated with injuries and disorders of the
shoulder and lower back.  For these conditions,  physicians often prescribe
steroidal drugs, non-steroidal anti-inflammatory drugs, pain relievers, and
muscle relaxants.  While these products reduce discomfort, they generally
do not  address impaired range of motion.

     The pharmaceutical industry is characterized by intense competition
and is subject to rapid and significant technological change.  Rapid
technological development may cause Esterom(R) solution and any other
products we develop to become obsolete before we can recoup all or any
portion of our development expenses.  Our competitors include major
pharmaceutical companies, biotechnology firms, universities and other
research institutions, both in the United States and abroad, which are
actively engaged in research and development of products in the therapeutic
areas being pursued by us.  Most of our competitors have substantially
greater financial, technical, manufacturing, marketing and human resource
capabilities than us.  In addition, many of our competitors have
significantly greater experience in testing new or improved therapeutic
products and obtaining regulatory approvals of products.  Accordingly, our
competitors may succeed in obtaining regulatory approval for their products
more rapidly than we are able to obtain approval for Esterom(R) solution.
If we commence significant commercial sales of our products, we will also
be competing with respect to manufacturing efficiencies and marketing
capabilities, areas in which we have no experience.

EMPLOYEES

     We have one full time executive officer, Thomas G. Tachovsky, our
President and Chief Executive Officer and one full time administrative

options to purchase 120,000 shares of our common stock, exercisable at
$4.00 per share for a period of five years, as a bonus for services rendered.

(3) Dr. Bailey's employment agreement terminated January 15, 1999.  During
1999, Dr. Bailey received options to purchase 107,500 shares of our common
stock at $4.00 per share, exercisable for five years from date of grant, as
compensation for services performed for us during the period from January

Bailey options to purchase 120,000 shares of our common stock, exercisable
at $4.00 per share for a period of five years, as a bonus for services rendered.


OPTIONS GRANTED TO DIRECTORS AND EXECUTIVE MANAGEMENT

     In 1998 our directors were granted a total of 240,000 options to
purchase common stock at $3.00 per share for a period of ten years. In 1998
and 1999 our executive management was granted a total of 610,000 options to
purchase common stock at $4.00 per share for a period of five years. In
1999 our Chief Executive Officer and President was granted 400,000 options
to purchase common stock at $5.00 per share. The options are subject to
vesting on performance standards being met and are exercisable for a period
of five years.


                                   27

DIRECTOR COMPENSATION

     Our directors do not receive cash compensation for services as
directors, although they are reimbursed for out-of-pocket expenses in
attending board of directors' meetings.  Each non-salaried director
receives options to purchase 20,000 shares of our common stock for each
year of service as a director.

STOCK COMPENSATORY PLAN

     In September 1998 our board of directors authorized an employee
stock-based compensation plan, the 1998 Stock Compensatory Plan, which
provides for the grant of options intended to qualify as "incentive stock
options" or "nonqualified stock options" within the meaning of Section 422
of the United States Internal Revenue Code of 1986 (the "Code"), as well as
stock bonus shares.  Incentive stock options are issuable only to
employees.  The purposes of the plan are to attract and retain the best
available personnel, to provide additional incentives to our employees, and
to promote the success of our business.

     We have reserved 300,000 shares of common stock for issuance under the
plan, which is administered by the entire board of directors.  Under the
plan, the board of directors determines which individuals will receive
options or bonus shares, the time period during which options may be
partially or fully exercised, the number of shares of common stock that may
be purchased under each option and the option price. Options granted under
the plan are generally exercisable for a period of ten years from the date
of grant at an exercise price not less than the fair market value of the
shares at the date of grant.  Options granted under the plan generally vest
over a one to three year period from the date of the grant.  To date, we
have issued 8,031 bonus shares for services and granted no options under
the plan.


NON-QUALIFIED STOCK OPTIONS GRANTED TO EXECUTIVE OFFICERS DURING 1999

     The following table sets forth certain information regarding grants of
stock options to our Executive Officers who received stock options during
1999.  The fair value of the option grant was estimated on the date of the
grant utilizing the Black-Scholes option pricing model with the following
assumptions: 51% to 100% volatility, five year life, risk free rate of
return of 5.5% to 6.2% and a 0% dividend yield.  None of the following
options have been exercised.

Securities and Exchange Commission and generally includes voting or
investment power with respect to securities.  Shares of common stock
issuable on exercise of currently exercisable or convertible securities or
securities exercisable or convertible within 60 days after the date of this
prospectus are deemed beneficially owned and outstanding for computing the
percentage owned by the person holding such securities, but are not
considered outstanding for computing the percentage of any other person.

              RELATED PARTY AND OTHER MATERIAL TRANSACTIONS

     During 1996 and 1997, we were advanced an aggregate of $83,873 by
Higgins D. Bailey, our former President, current Chairman and a principal
stockholder.  These advances were paid in full January 1998.

     We sublease approximately 800 square feet of office space from Thomas
T. Anderson, one of our principal stockholders.  The rent on the sublease
is $800 per month.  We believe this is a competitive lease rate for similar
real estate in the area where the office is located.

     On January 15, 1998, we  converted $1,710,487 of long-term debt and
accrued interest incurred for cash advances and past services associated
with research and development into 1,710,487 shares of our redeemable 8%
non-voting, non-cumulative Series A Preferred Stock at $1.00 per share.
The debt was owed to Higgins D. Bailey, Thomas T. Anderson and Lowell Somers.


     We owed Dr. James E. Wynn $1,500,000 for research and development
services provided from 1984 through 1997 as evidenced by an 8% Note due
December 31, 2000.  In January 1998 we converted this obligation to
1,500,000 shares of our non-voting, non-cumulative redeemable 8% Series A
preferred stock, valued at $1.00 per share.  In addition, in December 1997,
certain of our stockholders contributed shares of our common stock to Dr.
Wynn for research and development services (259,042 shares valued at
$712,000, or $2.75 per share).  The expense and related capital
contributions were reflected at December 31, 1997.  Dr. Wynn was
subsequently appointed one of our directors in February 1998.

     In January 1998, we granted Dr. Wynn a non-exclusive right for three
years to develop both improved products and new products from our
proprietary and confidential information.  Improved products are those that
contain the same active ingredients as Esterom(R) solution, but that are
formulated differently.  New products are those which are developed from
cocaine or a derivative and are separately patentable.  We will have all
rights to the improved and new products.  Dr. Wynn will receive a two
percent royalty on the net commercial sales of any improved products he
develops.  The royalty percentage on any new products he develops is to be
determined through negotiation.  If agreement is not reached, the royalty
is to be determined by an arbitrator with pharmaceutical industry experience.

     In April 1998 we entered into an agreement, as amended July 21, 1999,
with Western to assist us in completing the Phase III study and new drug
application phase for FDA approval of Esterom(R) solution for limited range
of motion associated with shoulder injuries and disorders.  We are paying
$880,400 over the period from April 1998 through January 5, 2001, and
$76,400 per quarter commencing January 2001 and continuing until NDA
submission.  We also granted Western options to purchase an aggregate of
450,000 shares of our common stock at $1.50 per share for a term of five
years.  The options vest at various times based upon performance.   Daniel
L. Azarnoff, M.D.,  a director of  Entropin is also a director of Western.


                                   30

<PAGE>
     In November 1999, we entered into an agreement with Western to assume
our obligations under our agreement with Therapeutic Management, Inc. to
perform tasks required to comply with FDA regulations applicable to the
conduct, coordination and management of the first Phase III trial.  Among
other things, WCCS is to select investigators, train clinical site
personnel, maintain the master file of all pre-study and study documents,
and prepare the Study Report to be submitted to the FDA.  We will pay
Western approximately $350,000 based on completion of certain project goals.


     These transactions are believed to be as favorable as obtainable from
third parties and were approved by directors who did not have an interest
in the transactions. However, at the time of the transactions we did not
have any independent disinterested directors to ratify the transactions.
All future material related party transactions and loans will be made or
entered into on terms that are no less favorable than those that can be
obtained from non-related third parties. In addition, all future material
related party transactions and loans, and any forgiveness of loans, must be
approved by a majority of our independent directors who do not have an
interest in the transactions and who have access, at our expense, to our
legal counsel or to independent legal counsel.


                        DESCRIPTION OF SECURITIES

     Our authorized capital stock consists of 50,000,000 shares of common
stock, $.001 par value per share, and 10,000,000 shares of preferred stock,
$.001 par value per share.

COMMON STOCK


     At February 28, 2000 there were 7,382,280 shares of common stock
outstanding held of record by 406 stockholders.  Each share of common stock
is entitled to one vote on all matters submitted to a vote of the
stockholders, and cumulative voting is not permitted.  Upon issuance,
shares of common stock are not subject to further assessment or call.
Subject to the prior rights of any series of preferred stock that may be
issued by us, holders of common stock are entitled to receive ratably such
dividends that may be declared by the board of directors out of funds
legally available therefor and are entitled to share ratably in all assets
remaining after payment of liabilities in the event of our liquidation,
dissolution or winding up.  Holders of common stock have no preemptive
rights or rights to convert their common stock into any other securities.
All outstanding shares of common stock are, and all shares of common stock
to be outstanding upon completion of this offering will be, fully paid and
nonassessable.


WARRANTS

     Each warrant will entitle the holder to purchase one share of common
stock at an exercise price of $______ per share (150% of the initial public
offering price of the shares).  The warrants will generally be exercisable
at any time for five years after the date of this prospectus, unless
earlier redeemed.  The warrants are redeemable by us, at a price of $0.25
per warrant:

     *    upon 30 days' prior written notice;

                                   31
<PAGE>
     *    no earlier than one year from the date of this prospectus; and then

     *    only if the closing bid price of the common stock equals or
          exceeds $______ (200% of the initial public offering price of the
          shares), per share for the 10 consecutive trading days
          immediately preceding the date of notice of redemption.

     If we give notice of our intention to redeem, a holder must either:

     *    sell or exercise the warrants before the date specified in the
          redemption notice; or

     *    accept the redemption price.

     The warrants will be issued in registered form under a warrant
agreement between us and Corporate Stock Transfer, Inc., as warrant agent.
The shares of common stock underlying the warrants, when issued upon
exercise of a warrant, will be fully paid and nonassessable.  We will pay
any transfer tax incurred as a result of the issuance of common stock to
the holder upon its exercise.

     The warrants contain provisions that protect the holders against
dilution by adjustment of the exercise price.  These adjustments will occur
if there is a merger, stock split or reverse stock split, stock dividend or
recapitalization and they could occur in other situations.  We are not
required to issue fractional shares upon the exercise of a warrant.  The
holder of a warrant will not possess any rights as our shareholder until he
or she exercises the warrant.

     A warrant may be exercised by surrendering the warrant certificate

     *    on or before the expiration or redemption date of the warrant at
          the offices of the warrant agent; with

     *    the form of "Election to Purchase" on the reverse side of the
          warrant certificate completed and executed as indicated; and

     *    payment of the exercise price by certified or bank check payable
          to the order of Entropin, Inc. for the number of shares for to
          which the warrant is being exercised.

In order for a holder to exercise the warrants, there must be

     *    a current registration statement in effect with the Securities
          and Exchange Commission; and,

     *    qualification in effect under applicable state securities laws or
          applicable exemptions from state qualification requirements, with
          respect to the issuance of common stock or other securities
          underlying the warrants.

                                   32
<PAGE>
      We have agreed to use all commercially reasonable efforts to cause a
registration statement with respect to such securities under the Securities
Act to be filed and to become and remain effective in anticipation of and
before the exercise of the warrants and to take such other actions under
the laws of various states as may be required to cause the sale of common
stock or other securities upon exercise of warrants to be lawful.  We will
not be required to honor the exercise of warrants if, in the opinion of our
board of directors with the advice of counsel, the sale of securities upon
exercise would be unlawful.

     For the life of the warrants, the holders have the opportunity to
profit from a rise in the market price of the common stock without assuming
the risk of ownership of the shares of common stock underlying the
warrants.  The warrant holders may be expected to exercise their warrants
at a time when we would, in all likelihood, be able to obtain any needed
capital by an offering of common stock on terms more favorable than those
provided for by the warrants.  Furthermore, the terms on which we could
obtain additional capital during the life of the warrants may be adversely
affected.

OTHER OPTIONS, WARRANTS AND CONVERTIBLE SECURITIES

     We have outstanding options and warrants to purchase an aggregate of
3,621,182 shares of our common stock, at exercise prices ranging from $1.50
to $5.00 per share and expiration dates ranging from July 2004 to February
2008.  Additionally, there are 230,500 shares issuable upon conversion of
the Series B preferred stock.

PREFERRED STOCK

     Our Board of Directors has the authority, without further action by
the stockholders, to issue up to 10,000,000 shares of preferred stock in
one or more series and to fix the powers, designations, preferences and
relative, participation, option or other rights thereof, including dividend
rights, conversion rights, voting rights, redemption terms, liquidation
preferences, sinking fund terms and the number of shares constituting any
series.  The issuance of preferred stock in certain circumstances may have
the effect of delaying, deferring or preventing a change in control of our
company, may discourage bids for our common stock at a premium over the
market price of the common stock, and may adversely affect the market price
of, and the voting and other rights of the holders of the common stock.

     Our Board of Directors has designated 3,210,487 shares of preferred
stock as Series A redeemable non-voting preferred stock, of which all were
issued to four holders of record in exchange for our promissory notes and
deferred compensation.  Series A preferred stock is designated as
redeemable eight (8%) percent non-cumulative non-voting preferred stock and
redeemable only from 20% of annual "Earnings", but not to exceed "Net Cash
Flow from Operating Activities" as those terms are defined under GAAP.  The
Series A preferred stock will be automatically canceled on January 16,
2005, if not fully redeemed within that time period.

     Our Board of Directors has designated 400,000 shares of preferred
stock as convertible Series B redeemable non-voting preferred stock, of
which 245,500 shares were issued and 230,500 shares remain outstanding held
by 33 holders of record.  Series B preferred stock is designated as redeemable

                                   33
<PAGE>
ten (10%) percent cumulative non-voting preferred stock with $.001 par
value and convertible on a one for one basis into common stock.  At our
election, annual dividends may be paid in cash and/or in shares of our
common stock, at the rate of one share of common stock for each $5.00 in
accrued dividends.   We may redeem at any time, in whole or in part based
on a pro rata basis with other holders of the Series B preferred stock, the
outstanding Series B preferred stock  upon 30 days' notice at $5.00 per
share plus accrued and unpaid dividends from the date of issuance up to the
expiration date.  All issued and outstanding Series B preferred stock must
be redeemed in full on or before July 15, 2003.


     We will not offer preferred stock to officers, directors or holders of
5% or more of our securities except on the same terms as offered to all
other existing shareholders or new shareholders, or unless the issuance of
preferred stock is approved by a majority of our independent directors who
do not have an interest in the transaction and who have access, at our
expense, to our legal counsel or to independent legal counsel.


STOCK TRANSFER AGENT

     Corporate Stock Transfer, Inc., Denver, Colorado is our transfer
agent.  The transfer agent's address is 3200 Cherry Creek Drive South,
Suite 430, Denver, Colorado 8020, and its telephone number is (303) 282-4800.

LIMITATIONS ON DIRECTORS' AND OFFICERS' LIABILITY

     Our Amended Articles of Incorporation limit the liability of directors
to stockholders for monetary damages for breach of a fiduciary duty except
in the case of liability: (i) for any breach of their duty of loyalty to us
or our stockholders; (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law; (iii) for
unlawful distributions as provided in Section 7-108-403 of the Colorado
Business Corporation Act; or (iv) for any transaction from which the
director derived an improper personal benefit.

     Our Articles of Incorporation and Bylaws provide for the
indemnification of our directors and officers to the maximum extent
permitted by law, including Section 7-109-102 of the Colorado Business
Corporation Act, against all liability and expense (including attorneys'
fees) incurred by reason of the fact that the officer or director served in
such capacity, or in a certain capacity for another entity at our request.
Section 7-109-102 of the Colorado Business Corporation Act provides
generally for indemnification of directors against liability incurred as a
result of actions, suits or proceedings if they acted in good faith and in
a manner they reasonably believed to be in or not opposed to our best interests.

                     SHARES ELIGIBLE FOR FUTURE SALE


     We presently have outstanding 7,382,280 shares of common stock of
which 6,028,082 shares are free trading.  However, we entered into lock-up
agreements with our officers and directors and 5% stockholders which,
except for 65,000 shares, requires that all remaining 4,184,621 shares of
common stock owned by such persons may not be sold for a period of one year
following the date of this prospectus without the prior written consent of
the representatives.


                                   34
<PAGE>

     We have agreed to register 711,200 shares of common stock under the
Securities Act of 1933, on behalf of certain stockholders.  We may be
required to file a registration statement as soon as practicable from the
date of the closing of this offering, at our expense, under the Securities
Act, with respect to these shares of common stock, and to use our best
efforts to effect the registration, subject to some conditions and
limitations.  At such time as these shares may be registered, they will be
free trading.  If we propose to register any of our securities under the
Securities Act, either for our own account or for the account of other
security holders, the holders of registration rights will be entitled to
notice of the registration and will be entitled to include, at our expense,
their shares in the registration


     We have issued 1,354,198 shares of common stock which are "restricted"
shares subject to restrictions upon resale under Rule 144 under the
Securities Act.  In general, under Rule 144, as currently in effect, any
person (or persons whose shares are aggregated), including  persons deemed
to be affiliates, whose restricted securities have been fully paid for and
held for at least one year from the later of the date of payment therefor
to us or acquisition thereof from an affiliate, may sell such securities in
brokers' transactions or directly to market makers, provided that the
number of shares sold in any three month period may not exceed the greater
of 1% of the then outstanding common stock or the average weekly trading
volume of the common stock during the four calendar weeks preceding such
sale.  Sales under Rule 144 are also subject to certain notice requirements
and the availability of current public information about us.  After two
years have elapsed from the later of the issuance of restricted securities
by us or their acquisition from an affiliate, such securities may be sold
without limitation by persons who are not affiliates under Rule 144.  The
1,354,198 shares of restricted stock become eligible for sale at various
times during the period April through September 2000, with 35,500 shares
subject to the lock-up agreement described above.


     Sales of substantial amounts of common stock by our stockholders under
Rule 144 or otherwise, or even the potential for such sales, are likely to
have a depressive effect on the market price of the shares of common stock
and warrants and could impair our ability to raise capital through the sale
of our equity securities.

                              UNDERWRITING


     The underwriters named below for whom Neidiger, Tucker, Bruner, Inc.
and Westport Resources Investment Services, Inc. are acting as

this prospectus.

     If any shares and warrants are purchased, the underwriters are
committed to purchase all of the 2,000,000 shares and warrants offered by
this prospectus, but not the 300,000 shares and the 300,000 warrants
subject to the over-allotment option.  The underwriting agreement also
provides that if an underwriter defaults, the purchase commitments of  the
non-defaulting underwriters may be increased or this offering may be
terminated.


     Once the underwriters have purchased the shares and warrants at the
public offering prices of $______ per share and $______ per warrant less
the 8% underwriting discount, they will offer the  shares and warrants in
units consisting of one share and one warrant to the public at the public
offering prices and to other broker-dealers who are members of the selling
group at that price minus a concession of $______ per share and $______ per
warrant.  The underwriters and selling group members may allow a discount
of $______ per share and $______ per warrant on sales to other broker-
dealers, including the underwriters.  After the public offering of the
shares and warrants, the public offering price, the concessions to selling
group members and the discount to other broker-dealers may be changed by
the representatives.


     We have granted the underwriters an option, expiring at the close of
business 45 days after the date of this prospectus, to purchase up to
300,000 additional shares and 300,000 additional warrants from us on the
same terms as apply to the sale of the shares and warrants set forth above.
The underwriters may exercise the option only to cover over-allotments
incurred in the sale of the shares and warrants.


     The representatives have informed us that they do not expect the
underwriters to confirm sales of shares and warrants on a discretionary basis.


     The following table summarizes the discounts and estimated expenses
that we will pay to the underwriters:

200,000 shares at $______ per share.  The representatives' warrants may not
be exercised for at least one year and will be restricted from sale,
transfer, assignment, or hypothecation for a period of five years from the
effective date of the offering, except to officers or partners (not
directors) of the representatives and members of the selling group and/or
their officers or partners.  The representatives' warrants are not
redeemable by us.  We have agreed to maintain an effective registration
statement

                                   36
<PAGE>
with respect to the issuance of the securities underlying the
representatives' warrants, if necessary, to allow their public resale
without restriction, at all times during the period in which the
representatives' warrants are exercisable, beginning one year after the
date of this prospectus.  Such securities are being registered on the
registration statement of which this prospectus is a part.


     The underwriting agreement provides for indemnification between us and
the underwriters against some liabilities, including liabilities under the
Securities Act of 1933 and for contribution by us and the underwriters to
payments that may be required to be made in respect of those liabilities.
Insofar as indemnification for liabilities under the Securities Act may be
permitted to our directors, officers and controlling persons under the
agreement between us and the underwriters, or otherwise, we have been
advised that in the opinion of the SEC this indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable.


     We have agreed that, for a period of one year following the completion
of this offering, we generally will not offer, sell, contract to sell,
grant any option for the sale or otherwise dispose of any of our common
stock without the consent of the representatives.  Our officers, directors
and the holders of 5% or more of our outstanding common stock (aggregating
4,184,621 shares) have agreed that for a period of one year following the
date of this prospectus, they will not offer, sell, contract to sell, grant
any option for the sale or otherwise dispose of any of our common stock,
other than intra-family transfers or transfers to trusts for estate
planning purposes, without the consent of the representatives, which will
not be unreasonably withheld.


     We have applied for listing of our common stock and warrants on the
Nasdaq SmallCap Market.  If listing is approved, our common stock will
trade under the symbol "ETOP" and our warrants will trade under the symbol
"ETOPW".

     Prior to this offering, our common stock has traded on the NASD OTC
Bulletin Board and there has been no public market for our warrants.  Stock
that trades on the OTC Bulletin Board can experience a relatively inactive
trading market, or low trading volume, high volatility and/or trading
prices that may not bear any reasonable relationship to the financial
condition or book value of the company.

     We can offer no assurances that the public offering price will
correspond to the price at which the common stock and warrants will trade
in the public market subsequent to the offering or that an active trading
market for the common stock and warrants will develop and continue after
the offering.


     The representatives on behalf of the underwriters may engage in over-
allotment, stabilizing transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Securities Exchange
Act of 1934.


     *    Over-allotment involves syndicate sales in excess of the offering
          size, which creates a syndicate short position.

     *    Stabilizing transactions permit bids to purchase the underlying
          security so long as the stabilizing bids do not exceed a
          specified maximum.

                                   37
<PAGE>
     *    Syndicate covering transactions involve purchases of the common
          stock and warrants in the open market after the distribution has
          been completed in order to cover syndicate short positions.


     *    Penalty bids permit the representatives to reclaim a selling
          concession from a syndicate member when the shares and warrants
          originally sold by the syndicate member are purchased in a
          syndicate covering transaction to cover syndicate short
          positions.


     These stabilizing transactions, syndicate covering transactions and
penalty bids may cause the price of the common stock and warrants to be
higher than it would otherwise be in the absence of such transactions.
These transactions may be effected on the Nasdaq SmallCap Market or
otherwise and, if commenced, may be discontinued at any time.

                              LEGAL MATTERS


     Certain legal matters with respect to the validity of the common stock
and the warrants to purchase common stock offered hereby will be passed
upon for us by Brenman Bromberg & Tenenbaum, P.C., Denver, Colorado.
Members of the firm of Brenman Bromberg & Tenenbaum, P.C. own 59,855 shares
of our common stock.  A. Thomas Tenenbaum, a director of Brenman Bromberg
& Tenenbaum, P.C., was our CEO prior to our merger with old Entropin.  The
Law Office of Gary A. Agron, Englewood, Colorado has acted as counsel to
the representatives in connection with this offering.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



   The Board of Directors and Stockholders
   Entropin, Inc.


   We  have  audited  the  accompanying  balance  sheet  of  Entropin,  Inc.  (a
   development  stage company) as of December 31, 1998 and 1999, and the related
   statements of operations,  changes in stockholders' equity (deficit) and cash
   flows for the years  then  ended and for the  period  from  August  27,  1984
   (inception)  through  December 31, 1999.  These financial  statements are the
   responsibility of the Company's management.  Our responsibility is to express
   an opinion on these financial statements based on our audits.

   We  conducted  our audits in  accordance  with  generally  accepted  auditing
   standards.  Those  standards  require  that we plan and perform the audits to
   obtain reasonable  assurance about whether the financial  statements are free
   of  material  misstatement.  An audit  includes  examining,  on a test basis,
   evidence supporting the amounts and disclosures in the financial  statements.
   An  audit  also  includes  assessing  the  accounting   principles  used  and
   significant  estimates made by management,  as well as evaluating the overall
   financial  statement  presentation.  We  believe  that our  audits  provide a
   reasonable basis for our opinion.

   In our opinion, the financial statements referred to above present fairly, in
   all  material  respects,  the  financial  position  of  Entropin,  Inc. as of
   December  31,  1998 and 1999 and the results of its  operations  and its cash
   flows for the years  then  ended and for the  period  from  August  27,  1984
   (inception)  through December 31, 1999, in conformity with generally accepted
   accounting principles.

   The accompanying  financial  statements have been prepared  assuming that the
   Company  will  continue as a going  concern.  As  discussed  in Note 1 to the
   financial  statements,  the Company is in the development  stage and has been
   primarily  involved in research  and  development  activities,  resulting  in
   significant  losses  and an  accumulated  deficit  at  December  31,  1999 of
   $12,640,814  These  conditions raise  substantial  doubt about its ability to
   continue as a going concern.  Management's plans regarding those matters also
   are  described  in  Note 1.  The  financial  statements  do not  include  any
   adjustments that might result from the outcome of this uncertainty.

                           NOTES TO FINANCIAL STATEMENTS
                             December 31, 1998 and 1999




1. Organization and summary of significant accounting policies

   Organization:

   Entropin, Inc., a Colorado corporation, was organized in August 1984, to be a
   pharmaceutical  research company developing  Esterom(R) solution, a topically
   applied  compound for the  treatment of impaired  range of motion  associated
   with acute  lower back  sprain and acute  painful  shoulder.  The  Company is
   considered  to be a  development  stage  enterprise  as more fully defined in
   Statement No. 7 of the Financial Accounting Standards Board.  Activities from
   inception  include research and  development,  seeking the U.S. Food and Drug
   Administration  (FDA)  approval  for  Esterom(R)  solution,  as  well as fund
   raising.

   On January 15, 1998, the Company  consummated an agreement and plan of merger
   with Vanden Capital Group, Inc., a Colorado  corporation,  (Vanden), in which
   Vanden  acquired  all of the  issued  and  outstanding  common  shares of the
   Company (see Note 5). The Company was merged into Vanden,  and Vanden changed
   its name to Entropin,  Inc. For accounting purposes, the acquisition has been
   treated as a recapitalization of the Company, based upon historical cost, and
   a reverse acquisition with the Company as the acquirer.

   Basis of presentation and management's plans:

   The Company's  financial  statements  have been  presented on a going concern
   basis which  contemplates  the realization of assets and the  satisfaction of
   liabilities  in  the  normal  course  of  business.  The  Company  is in  the
   development stage and has been primarily involved in research and development
   activities.  This has  resulted  in  significant  losses  and an  accumulated
   deficit  at  December  31,  1999  of  $12,640,814.  The  Company's  continued
   existence  is  dependent  on its  ability  to obtain the  additional  funding
   necessary to complete the FDA approval  process for  Esterom(R)  solution and
   market the product.

   As described in Note 5, the Company successfully  completed  recapitalization
   of the Company in January  1998.  The Company also sold private  offerings of
   245,500 shares of Series B convertible  preferred stock for gross proceeds of
   $1,227,500  (Note 4),  $200,000 of convertible  notes payable,  and 1,508,700
   shares of common  stock for gross  proceeds  of  $4,664,800  (Note 5),  which
   offerings  provide  liquidity  to the  Company for  current  operations.  The
   Company raised  sufficient  funds in 1999 to complete the first part of a two
   part  Phase III  clinical  trial  program  associated  with the FDA  approval
   process for the  treatment  of acute  painful  shoulder.  The trials began in
   November  1999 and the first part is scheduled  for  completion  in mid 2000.
   Management  is  confident  that it will raise the added  funds  necessary  to
   complete the second part of the Phase III trials,  ancillary  studies and the
   New Drug Application (NDA) process,  as well as additional funds for research
   and development and working  capital via a secondary  securities  offering in
   early 2000. The Company estimates it will require additional funding of up to
   $10 million to successfully  complete the FDA approval process. The financial
   statements do not include any adjustment  relating to the  recoverability and
   classification of recorded asset amounts or the amount and  classification of
   liabilities or other  adjustments  that might be necessary should the Company
   be unable to continue as a going concern in its present form.

                           NOTES TO FINANCIAL STATEMENTS
                             December 31, 1998 and 1999




1. Organization and summary of significant accounting policies (continued)

   Use of estimates:

   The preparation of financial statements in conformity with generally accepted
   accounting  principles  requires management to make estimates and assumptions
   that affect the reported  amounts of assets and liabilities and disclosure of
   contingent assets and liabilities at the date of the financial statements and
   the reported  amounts of revenues and expenses  during the reporting  period.
   Actual results could differ from those estimates.

   Income Taxes:

   The Company provides for income taxes utilizing the liability  approach under
   which  deferred  income  taxes are  provided  based upon enacted tax laws and
   rates applicable to the periods in which the taxes become payable.

   Property and equipment:

   Office furniture and equipment is recorded at cost. Depreciation commences as
   items are placed in service and is computed  on a  straight-line  method over
   their estimated useful lives of three years.

   Leasehold  improvements are recorded at cost and amortized over the five-year
   term of the lease.

   Patents:

   Patents are stated at cost less accumulated  amortization which is calculated
   on a  straight-line  basis over the useful lives of the assets,  estimated by
   management to average 16 years.  Research and development costs and any costs
   associated  with  internally  developed  patents (with the exception of legal
   costs) are expensed in the year incurred.

   The  Company  holds  eight U.S.  patents  issued  between  1984 and 1998 with
   expiration  dates  ranging from  September  2001 to June 2014.  These patents
   include two material  composition patents covering the molecules contained in
   Esterom(R) solution that expire in 2012 and 2013. The Company's three initial
   patents  were based on methods of  treatment of  rheumatoid  arthritis  using
   benzoylecgonine  and  related  compounds,  and the  five  subsequent  patents
   include compound,  composition and method claims involving  derivative of the
   compounds  represented in the earlier patents. The Company believes that some
   of the patents may be eligible for extensions of up to five years.

   In December 1993, the Company filed an International Patent Application under
   the Patent  Cooperation  Treaty claiming  compounds present in the Esterom(R)
   solution  formulation  from which eight  separate  patent  applications  were
   derived - Australia,  Canada, Europe, Hungary, Japan, New Zealand, Norway and
   Poland. In addition,  the Company filed patent applications in China, Israel,
   Mexico,  South  Africa and  Taiwan.  From these  foreign  applications,  nine
   patents have been issued to date.

1. Organization and summary of significant accounting policies (continued)

   Impairment of long-lived assets:

   The Company  evaluates  the  potential  impairment  of  long-lived  assets in
   accordance  with  Statement  of  Financial   Accounting  Standards  No.  121,
   "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
   to be  Disposed  of".  The  Company  annually  reviews the amount of recorded
   long-lived assets for impairment.  If the sum of the expected cash flows from
   these assets is less than the carrying amount,  the Company will recognize an
   impairment loss in such period.

   Cash equivalents:

   For the purposes of the  statement of cash flows,  the Company  considers all
   highly liquid debt  instruments  purchased with a maturity of three months or
   less to be cash equivalents.

   Deferred stock offering costs:

   Deferred stock offering costs  represent costs incurred to December 31, 1999,
   in connection with the proposed offering of common stock (see Note 5). In the
   event that such  offering is  successful,  costs  incurred as of December 31,
   1999, and additional  costs incurred  subsequent to that date will be charged
   against the proceeds of the offering; if the offering is not successful,  the
   costs will be charged to operations.

   Concentrations of credit risk:

   Financial instruments which potentially subject the Company to concentrations
   of credit risk consist principally of cash and cash equivalents.  The Company
   places its cash with high quality financial institutions. At times during the
   periods, the balances at financial institutions exceeded FDIC limits.

   Stock-based compensation:

   The Company  has  adopted  Statement of Financial  Accounting  Standards  No.
   123, Accounting for  Stock-Based  Compensation.  Compensation costs for stock
   options is  measured as  the excess, if any, of the fair value of the options
   at date of grant over the exercise price.

2. Related party transactions

   Lease agreement:

   The Company  subleases  approximately  800 square feet of office space from a
   principal stockholder, at $800 per month.

2. Related party transactions (continued)

   Conversion of long-term debt - stockholders:

   On January 15, 1998, the Company  converted  $1,710,487 of long-term debt and
   accrued  interest,  incurred for cash advances and past  services  associated
   with  research  and  development,  into  1,710,487  shares of 8%  non-voting,
   non-cumulative  Series A preferred stock at $1.00 per share (see Note 4). The
   debt was owed to significant stockholders.

3. Income taxes

   The  consummation  of the stock  exchange  with  Vanden and the  issuance  of
   preferred  stock in January  1998 (see Note 5),  resulted  in a change in the
   Company's  tax status from an S  corporation  to a taxable  corporation.  The
   effect of the change is to provide for income tax based upon reported results
   of  operations,  and to  provide  deferred  tax  assets  and  liabilities  on
   temporary differences between reported earnings and taxable income.

   At December 31, 1999,  the Company has net operating  loss  carryforwards  of
   approximately $3,558,000 and future tax deductions of $6,946,000 which may be
   used to offset  future  taxable  income.  The  future tax  deductions  result
   primarily from utilizing the cash basis for income tax reporting purposes and
   unearned   stock   compensation.   The   difference   between  the  tax  loss
   carryforwards  and future  tax  deductions  and the  cumulative  losses  from
   inception  result from the losses  previously  incurred by the S corporation.
   The net operating loss carryforwards  expire in 2018 and 2019.  Approximately
   $250,000 of the net operating loss  carryforward  is limited as to the amount
   which may be used in any one  year.  At  December  31,  1998 and 1999,  total
   deferred tax assets and the valuation allowance are as follows:

                                                    1998         1999

   deferred tax assets cannot be reasonably assured.

4. Redeemable preferred stock

   In  December  1997,  the Board of  Directors  approved  an  amendment  to the
   Articles of Incorporation to authorize  10,000,000  shares of $.001 par value
   preferred  stock. On January 15, 1998, the Company issued 3,210,487 shares of
   its Series A redeemable,  non-voting,  non-cumulative  8% preferred  stock in
   exchange  for an  aggregate  $1,710,487  of notes  payable  to  shareholders,
   accrued  interest,  and a $1,500,000  compensation  agreement.  The annual 8%
   dividend is based upon a $1.00 per share  value,  and is only  payable out of
   earnings.

   The Series A preferred stock is subject to mandatory  redemption.  The shares
   are redeemable only from 20% of annual  earnings,  but not exceeding net cash
   flow from, operating activities, and will automatically cancel on January 16,
   2005, if not fully redeemed.  The Company may voluntarily  redeem outstanding
   shares of preferred stock at $1 per share.

   In July 1998, the Company  completed a private placement of 245,500 shares of
   Series B  preferred  stock at $5.00 per  share,  for total  net  proceeds  of
   $1,142,750.  The Series B preferred  stock is designated  as  redeemable  10%
   cumulative  non-voting  convertible preferred stock with $.001 par value. The
   shares  are  convertible  on a one for  one  basis  into  common  stock.  The
   dividends  accrue  at the  rate of $.50  per  share  per  annum  and are paid
   annually  commencing  July  15,  1999.  At  the  Company's  election,  annual
   dividends  were paid in shares of the Company's  common stock valued at $5.00
   per share at July 15, 1999.  Dividends  are added to net loss in  determining
   net loss per  common  share.  15,000  Series B  preferred  shares  have  been
   converted as of December 31, 1999. All unconverted shares will be redeemed at
   $5.00 per share on or before July 15, 2003.

5. Stockholders' equity

   Recapitalization:

   On December 9, 1997, the Company entered into an agreement and plan of merger
   with Vanden to exchange all of the issued and  outstanding  common  shares of
   the Company,  in exchange for  5,220,000  shares of Vanden's  $.001 par value
   common stock, in a reverse acquisition.

5. Stockholders' equity (continued)

   Pursuant to the  agreement,  Vanden  agreed to have cash of  $220,000  and no
   unpaid liabilities at the effective date of the transaction. The exchange was
   consummated  on January 15, 1998 and is presented on the statement of changes
   in stockholders'  equity as an issuance of 480,051 shares of common stock for
   cash proceeds of $220,100  pursuant to  recapitalization.  In connection with
   the  recapitalization,  the Company issued options to purchase 180,001 shares
   of its $.001 par value  common stock for cash of $100 and options to purchase
   an additional 180,001 shares of common stock for $2.80 per share, as required
   by a management  advisory services contract as compensation for arranging the
   merger. The difference between the fair value of the stock,  estimated by the
   Company to be $2.75 per share, and the purchase price for the initial 180,001
   shares was treated as  additional  cost of the merger and charged to capital,
   consistent with accounting for the reverse acquisition as a recapitalization.
   The net effect of this  transaction  was to record an  increase  and  related
   decrease to additional paid-in capital of $495,000.  The remaining options to
   acquire 180,001 shares are exercisable for a five-year period.

   Following the exchange, the Company's shareholders owned approximately 95% of
   the  outstanding  common stock of Vanden.  The reverse  acquisition  has been
   accounted  for as a  recapitalization  of the Company  based upon  historical
   cost.  Accordingly,  the number of authorized and issued common  shares,  par
   value of common stock and  additional  paid-in  capital have been restated on
   the  balance  sheet  and  the  statement  of  stockholders'  equity  to  give
   retroactive effect to the recapitalization.

   Private placements:

   In January 1998, the Company  completed a private placement of 300,000 shares
   of its $.001 par value common stock for gross proceeds of $825,000, $2.75 per
   share.

   In April 1999, the Company completed a private placement of 497,500 shares of
   its $.001 par value  common  stock at $2.00 per share for gross  proceeds  of
   $995,000.

   In June 1999,  the Company sold  304,750  shares of common stock at $4.00 per
   share for gross proceeds of $1,219,000 in a private placement.

   In September  1999,  the Company sold 406,450 shares of common stock at $4.00
   per share for gross proceeds of $1,625,800 in a private placement.

   Proposed public offering:

   In June 1999, the Company entered into a letter of intent with an underwriter
   to conduct a public offering of 2,000,000  units  (consisting of one share of
   common  stock and one  warrant to  purchase  one share of common  stock) with
   gross proceeds of approximately $12 to $14 million.  The per share price will
   be determined by mutual agreement between the Company and underwriter.

   Other issuances of common stock:

   In March 1999,  the  Company  received  cash  proceeds  aggregating  $200,000
   pursuant  to eight 10%  convertible  note  payable  agreements  with  various
   unrelated  individuals  and entities.  Each note was  unsecured,  and due the
   earlier of 90 days from the date of issue or upon the  receipt by the Company
   of certain  proceeds  from a private  offering of its  securities.  Each note
   agreement  also provided a warrant  granting the holder the right to purchase
   three and one half restricted  shares of the Company's  common stock for each
   dollar of  principal  received by the  Company,  for an  aggregate of 700,000
   shares. The warrants have certain  registration  rights, an exercise price of
   $3.00 per share and are  exercisable  for five years from the date the shares
   become freely tradable. To the extent that the shares underlying the warrants
   are not registered within two years of grant date, the holders have the right
   to exercise the warrants on a cashless  basis for a period of five years.  In
   April 1999, the Company amended the note agreements to allow the note holders
   to  convert  their  promissory  notes to shares of common  stock at $2.00 per
   share.  Upon issuing the amendment,  all note holders  converted their notes,
   including  accrued  interest,  to common stock  resulting in new issuances of
   common stock totaling 100,831 shares. Due to the immediate  conversion of the
   notes to common  stock,  none of the proceeds  received  upon issuance of the
   notes payable were  allocated to the  warrants.  The net effect of allocating
   proceeds  to the  warrants  would  be an  increase  and  corresponding  equal
   decrease in additional paid-in capital.

   Stock options and warrants:

   In April  1998,  the  Company  granted  stock  options to Western  Center for
   Clinical  Studies,  Inc. to purchase  450,000 shares of the Company's  common
   stock at $1.50 per share (see Note 7).

   In August 1998, the Company  granted to each director  options to purchase up
   to  60,000  shares  of the  Company's  common  stock  (300,000  shares in the
   aggregate), exercisable for ten years at $3.00 per share. Options to purchase
   20,000 shares each were fully vested February 1999, and the remaining  40,000
   vest on a pro rata basis monthly  through  February  2001.  Should any of the
   directors  cease to serve on the board of directors,  all non-vested  options
   shall be forfeited.  During 1999, a director resigned and options to purchase
   35,000 shares were canceled.

   In September  1998, the board of directors  approved a compensation  plan for
   three officers and directors,  to serve on a management  team, which included
   stock options in lieu of salary aggregating  295,000 shares,  exercisable for
   five years at $4.00 per share.  Options to purchase 125,000 shares were fully
   vested in December 1998 and January 1999, and the remaining 170,000 vested on
   a pro rata basis  monthly  through  June 30,  1999.  During  1999, a director
   resigned  and options to purchase  20,000  shares were  canceled.  During the
   period July through  October 1999, the Company  provided its management  team
   additional  stock  options  in lieu of salary to  purchase  an  aggregate  of
   430,000  shares of common  stock.  The options are  exercisable  at $4.00 per
   share, and were fully vested at December 31, 1999.

5. Stockholders' equity (continued)

   In October 1998, the Company  provided a 100,000 share stock option agreement
   to an organization,  with whom the Company entered into a one year consulting
   agreement.   The  consultant  provided  investor  relations  and  development
   services,  and  received  compensation  of $5,000 per month.  The options are
   exercisable  at $4.00 per share and vest 50,000  shares as of the date of the
   agreement,  25,000  shares on March 31,  1999 and  25,000  shares on June 30,
   1999.  During May and August 1999, the organization  exercised  options for a
   total of 20,000 shares of common stock. In July 1999, the Company also agreed
   to provide the  organization  with an additional  cash payment of $10,000,  a
   warrant to purchase up to an additional 23,500 shares of the Company's common
   stock,  as well as a  finder's  fee for all  funds  received  by the  Company
   related to fund raising  activities  attributable  to the  organization.  The
   warrant is exercisable for five years at $4.00 per share.

   In December  1998, the board of directors  approved a resolution  whereby the
   Company  granted to a company and an individual two stock options to purchase
   up to 17,500  shares of the  Company's  common  stock  (35,000  shares in the
   aggregate)  in exchange for services the Company  received  during 1998.  The
   options are exercisable at $4.00 per share for a period of five years and are
   fully vested as of the date of the resolution.

   On March 11,  1999,  the  Company  provided  a  175,000  share  stock  option
   agreement  to an  organization  with  whom  the  Company  entered  a one year
   consulting  agreement.  The Company may  terminate  the  agreement  after six
   months. The organization  provides  investment  community relations services,
   and receives  compensation of $3,000 per month.  The option is exercisable at
   $3.00 per  share.  The option  provides  certain  registration  rights to the
   holder,  and is exercisable the earlier of January 1, 2000 or when the shares
   become registered. The exercise period is five years from the date the shares
   become freely tradable.  To the extent that the shares underlying the options
   are not registered within two years of grant date, the holders have the right
   to exercise the options on a cashless basis for a period of five years.

   On March 15,  1999,  the  Company  provided  a 300,000  share  stock  warrant
   agreement  to an  organization,  with whom the Company  entered into an eight
   month consulting  agreement.  The organization was also to be paid a retainer
   of  $7,000  per  month.   The  organization  was  engaged  to  raise  capital
   aggregating $8 million and provide financial advisory services.  The warrants
   were exercisable at $4.50 per share. In July 1999, the Company terminated the
   consulting agreement. As final settlement,  the organization received $69,084
   for fees and expenses  earned in conjunction  with fund raising and a warrant
   to purchase 50,000 shares of the Company's common stock, exercisable for five
   years at $4.00 per share. The previous warrants to purchase 300,000 shares of
   the Company's common stock were canceled.

   extent that any of the funding is not attributable to the  organization.  The
   term of the  warrants  will be through  March 22,  2004.  The Company had not
   received  any  funding  during  1999  attributable  to the  organization  and
   warrants  to  purchase  200,000  shares  have been  canceled.  The  remaining

   a 12 month period from date of grant.

   In  June  and  July  1999,  the  Company  provided  stock  option  agreements
   aggregating 120,000 shares to an organization  providing financial consulting
   services.  The options are  exercisable  at $3.00 to $4.00 per share and vest
   25,400 shares as of June 30, 1999,  20,000 shares at August 5, 1999, with the

5. Stockholders' equity (continued)

   At December 31, 1999,  outstanding options and warrants aggregating 1,565,182
   shares have certain  registration rights and options and warrants aggregating
   2,295,181 shares contain certain cashless exercise provisions.

   4,114,564 shares of  the 4,179,564 shares owned  by  the Company's directors,
   officers, and 5% or greater stockholders, and substantially all of the shares
   underlying  the  outstanding  options  and  warrants  are  subject to lock-up
   agreements  which  expire one year after  the effective date of  the proposed
   public offering unless released sooner upon written consent.

   Unearned stock compensation:

   At December 31, 1999,  the Company had  outstanding an aggregate of 3,621,182
   options and warrants of which 2,436,000 were granted at purchase prices lower
   than fair value of the stock at date of grant,  including  the stock  options
   and warrants  disclosed  above and the 450,000  granted to the Western Center
   for Clinical Studies, Inc. (see Note 7).  The excess of the fair value at the
   grant date of the  options and  warrants,  over the  exercise  price has been
   recorded as  additional  paid-in  capital and  unearned  stock  compensation.
   Unearned  compensation  is being  amortized to research and  development  and
   general and administrative  expense over the term of the related  agreements,
   as follows:

                                        ==========  ==========   ==========


   The fair value of each option and warrant  grant is  estimated on the date of
   grant  using  the  Black-Scholes  option  pricing  model  with the  following
   assumptions used for grants in 1998 and 1999:  dividend yield of 0%, expected
   volatility  of 51% - 100%,  risk-free  interest  rate of 4.63% -  6.22%,  and
   expected life of five to nine years.

6. Basic and diluted net loss per share

   Basic net loss per share is based on the  weighted  average  number of shares
   outstanding during the periods.  Shares issued for nominal  consideration are
   considered  outstanding  since  inception.  Diluted  loss per share  excludes
   dilution from common stock equivalents,  as exercise of the outstanding stock
   options and warrants would have an anti-dilutive  effect.  The 10% cumulative
   dividends on Series B preferred stock have been accrued and added to net loss
   for the purpose of determining net loss and net loss per share  applicable to
   common shareholders.

7. Commitments and contingencies

   Compensation agreements:

   In 1993,  the Company  entered  into a 30 year  compensation  agreement  with
   I.B.C. limited partners owning 64.28% of the I.B.C. Limited Partnership.  The
   limited  partnership  participated  in the early  development  of  Esterom(R)
   solution (the  medicine) and owned the patent rights to three patents and all
   intellectual  property rights. Under the terms of the Agreement,  the Company
   acquired all of the patent and  intellectual  property rights in exchange for
   certain  compensation  to the limited  partners,  which is dependent upon the
   Company's  receipt  of a  marketing  partner's  technological  access fee and
   royalty  payments.  The  limited  partnership  was  subsequently   dissolved.
   Compensation  under the  agreement  includes a bonus payment of $96,420 to be
   paid at the  time  the  Company  is  reimbursed  by a drug  company  for past
   expenses  paid  for  development  of the  medicine,  as well as  64.28%  of a
   decreasing payment rate (3% to 1%) on cumulative annual royalties received by
   the Company.  As of December 31, 1999, no liabilities  have been accrued with
   respect to this agreement.

   In a separate  agreement with certain  former I.B.C.  limited  partners,  the
   Company has agreed to pay the partners 35.72% of a decreasing  earned payment
   (3% to 1% on  cumulative  annual  sales of  products  by the  Company)  until
   October 10, 2004.  From October 10, 2004 until October 10, 2014,  the Company
   will pay the partners  17.86% of the earned  payment.  In accordance with the
   agreement,  the Company has agreed to pay these former  limited  partners the
   amount of $40,000 and a minimum earned payment of $3,572 per calendar quarter
   beginning on December 1, 1989.  Such minimum  earned  payment is payable when
   the Company is either reimbursed for expenses paid for the development of the
   medicine or from the first  income  received by the Company from net sales of
   the  medicine.  The quarterly  payments are to be applied  against the earned
   payment to be received by the limited partners.  As of December 31, 1999, the
   liability  accrued  with  respect to this  agreement  totaled  $184,071.  The
   Company  will receive a credit  against the earned  payments of 50% of monies
   which are expended in  connection  with  preparing,  filing,  obtaining,  and
   maintaining patents involved with the sold rights.

   Development and Supply Agreements:

   On January 1, 1997, the Company entered into ten year  Development and Supply
   Agreements  with  Mallinckrodt,   Inc.  to  develop  all  of  the  chemistry,
   manufacturing  and  controls  to comply with the drug master file of the Food
   and Drug  Administration  as well as  supply  the  bulk  active  product  for
   marketing.  In exchange for these services,  Mallinckrodt  received exclusive
   rights as a  supplier  of the bulk  active  product  to the  Company in North
   America.  The price of the ingredient is based on the price of the components
   in the bulk active product.

   In addition, pursuant to the agreements, the Company has granted Mallinckrodt
   a right of first  refusal to supply the  Company's  requirements  of the bulk
   active product in all other parts of the world outside of North America.

7. Commitments and contingencies (continued)

   The Company is dependent upon Mallinckrodt,  Inc. to provide the raw material
   from which the active ingredients in Esterom(R) solution are derived.

   License Agreement:

   In January 1998, the Company entered into an agreement with a director of the
   Company,  whereby the Company granted the director a  non-exclusive  right to
   make, import and use the Company's product,  Esterom(R)  solution,  under the
   Company's licensed patents and to use the Company's confidential  information
   to  develop  new  products  that  contain  the  same  active  ingredients  as
   Esterom(R)  solution,  but are  formulated  differently.  All  rights  to the
   improved  products will remain the exclusive  property of the Company and the
   director will receive a two percent  royalty on the net sales of all improved
   products,  and a negotiated  royalty on new products.  The expiration date of
   this agreement is January 1, 2003.

   Management agreements:

   During  April  1998,  the  Company  entered  into  an agreement  with Western
   Center for Clinical  Studies,  Inc. (WCCS),  to provide  assistance in taking
   Esterom(R) solution through the clinical trials and New Drug Application(NDA)
   approval.  The  agreement was  subsequently  amended in July 1999 and October
   1999.  The  Company is required to pay  management  fees of $880,400  through
   January  5,  2001  and  $76,400  per  quarter  commencing  January  2001  and
   continuing  until NDA submission.  The Company also has granted stock options
   to WCCS to  purchase  450,000  shares of Entropin  common  stock at $1.50 per
   share.  The  options  will  expire  five  years  from  the date  they  become
   exercisable. The shares underlying the options are also provided with certain
   registration  rights. The difference between the fair value of the options at
   date of grant and the exercise price, totaling approximately $1,950,000 using
   the  Black-Scholes  option  pricing  model,  has been  recorded as additional
   paid-in  capital  and  unearned  stock   compensation.   The  unearned  stock
   compensation is being amortized to expense on a straight-line  basis over the
   initial 33 month term of the agreement.

   In August  1999,  the Company  entered  into an  agreement  with  Therapeutic
   Management,  Inc. to provide clinical trial  management  services and monitor
   all aspects of Esterom(R)  solution's Phase III clinical studies. In November
   1999, the Company entered into an agreement with WCCS to assume the Company's
   obligations under Therapeutic Management Agreement. The Company will pay WCCS
   approximately $350,000 based upon completion of certain project goals.

8. Financial instruments

   The  carrying  values  of cash and cash  equivalents,  accounts  payable  and
   accounts  payable  -  related  party  approximates  fair  value  due  to  the
   short-term maturities of these instruments.

   The Company believes that it is not practical to estimate a fair market value
   different  from  the  carrying  value  of  long-term  debt.  Long-term  debt,
   excluding  the deferred  royalty  agreement,  was converted  into  redeemable
   preferred stock on January 15, 1998. Both the redeemable  preferred stock and
   the  deferred  royalty  agreement  have  numerous  features  unique  to these
   securities and agreements as described in Notes 4 and 7.

                 INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

A.   The Colorado Business Corporation Act (the "Act") allows
indemnification of directors, officers, employees and agents of the Company
against liabilities and reasonable expenses, including attorneys' fees,
incurred in any proceeding in which an individual is made a party because
he was a director, officer, employee or agent of the Company if such person
conducted himself in good faith and reasonably believed his actions were
in, or not opposed to, the best interests of the Company, and with respect
to any criminal action or proceeding, had no reasonable cause to believe
his conduct was unlawful.  A person must be found to be entitled to
indemnification under this statutory standard by procedures designed to
assure that disinterested members of the Board of Directors have approved
indemnification or that, absent the ability to obtain sufficient numbers of
disinterested directors, independent counsel or shareholders have approved
the indemnification based on a finding that the person has met the
standard.  The Company's By-Laws provide that the Registrant shall have the
power to indemnify its officers, directors, employees and agents to the
extent permitted by the Act.

B.   Article VIII of the Registrant's Amended and Restated Articles of
Incorporation provides for the elimination of personal liability for
monetary damages for the breach of fiduciary duty as a director except for
liability (i) resulting from a breach of the director's duty of loyalty to
the Registrant or its shareholders; (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of the
law; (iii) for approving payment of  distributions to shareholders to the
extent that any such actions are illegal under the Act; or (iv) for any
transaction from which a director derives an improper personal benefit.
This Article further provides that the personal liability of the
Registrant's directors shall be eliminated or limited to the fullest extent
permitted by the Act.

C.   The Underwriting Agreement between the Registrant and the Underwriters
provides that the Underwriters will indemnify and hold harmless the
Registrant, the directors of the Registrant, and each person, if any, who
controls the Registrant within the meaning of Section 15 of the Securities
Act of 1933, as amended (the "1933 Act"), against any and all losses,
claims, demands, liabilities and expenses (including reasonable legal or
other expenses) to which it may become subject, arising out of or based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement or in any Blue Sky Application or
the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not
misleading, resulting from the use of written information furnished to the
Registrant by the Underwriters or any participating dealer for use in the
preparation of the Registration Statement or in any Blue Sky Application.

     There is no pending litigation or proceeding involving a director,
officer, employee or other agent of the Company as to which indemnification
is being or may be sought, and the

                                  II-1

<PAGE>

Company is not aware of any other pending or threatened litigation that may
result in claims for indemnification by any director, officer, employee or
other agent.

     The offers and sales were made in reliance upon the exemption from
registration provided by Section 4(2) of the 1933 Act and/or Regulation D
and Rule 506 adopted thereunder.  All of the purchasers are known by Old
Entropin's (now the Registrant's) Chairman, Higgins D. Bailey, or were
referred to him by other purchasers in this offering.  Based upon the
written representations made by the purchasers and other information known
to the Registrant, the Registrant believes all of the purchasers were
Accredited Investors as that term is defined in Rule 501 of Regulation D.
No broker/dealers were involved in the sales and no commissions were paid.
All purchasers represented that they purchased the securities for
investment, and all certificates issued to the purchasers were impressed
with a restrictive legend advising that the shares represented by
certificates may not be sold, transferred, pledged or hypothecated without
having first been registered or the availability of an exemption from
registration established.  Stop transfer instructions have been placed
against the transfer of these certificates by the Registrant's Transfer Agent.

                                   II.

     In November 1997, Old Entropin issued an 8% note in the principal
amount of $1,500,000 maturing December 31, 2000 payable to James E. Wynn as
compensation for research and development services provided since the
inception of the Company.  In January 1998, Old Entropin converted this
obligation to 1,500,000 shares of its redeemable 8% non-voting, non-
cumulative Series A preferred stock, at $1.00 per share.   The issuance of
the promissory note and the subsequent conversion into shares of Series A
preferred stock were made in reliance upon the exemption from registration
provided by Section 4(2) of the Act.   The purchaser represented that he
acquired the securities for investment, and all certificates issued to the
purchaser were impressed with a restrictive legend advising that the shares
represented by certificates may not be sold, transferred, pledged or
hypothecated without having first been registered or the availability

Old Entropin had accrued $1,710,487, including interest, in long-term debt
owed to the abovementioned stockholders at December 31, 1997.   On January
15, 1998, Old Entropin converted all of such long-term debt plus accrued
interest into 1,710,487 shares of Old Entropin's redeemable 8% non-voting,
non-cumulative Series A Preferred Stock at $1 per share.  The issuance of
the shares of Series A preferred stock was made in reliance upon the
exemption from registration provided by Section 4(2) of the Act.   The
purchasers represented that they acquired the securities for investment,
and all certificates issued to the purchasers were impressed with a

  In December, 1997, Old Entropin entered into an agreement with LMU &
Company ("LMU").  As partial consideration for LMU's services under the
agreement, Old Entropin issued an option to purchase 180,001 shares of Old
Entropin's common stock, exercisable for cash of $100.  The issuance of the
option to LMU was made in reliance upon the exemption from registration
provided by Section 4(2) of the Act.   LMU represented that LMU acquired
the option for investment and not with a view to distribution.  LMU
exercised its option in January 1998.  Stop transfer instructions have been
placed against the transfer of these certificates by the Registrant's
transfer agent.

  The exchange of Old Entropin shares for shares of the Registrant was
effected under the exemption from registration provided under Section 4(2)
of the Act and Rule 506 of Regulation D promulgated thereunder, for
transactions not involving a public offering.  Based upon the written
representations made by the investors and other information known to the
Registrant, the Registrant believes all of the investors were Accredited
Investors as that term is defined in Rule 501 of Regulation D.  All
investors represented that they purchased the securities for investment,
and all certificates issued to the investors were impressed with a
restrictive legend advising that the shares represented by certificates may
not be sold, transferred, pledged or hypothecated without having first been
registered or the availability of an exemption from registration
established.  No broker/dealers were involved with the exchange, and no
commissions were paid.  Stop transfer instructions have been placed against
the transfer of these certificates by the Registrant's Transfer Agent.

  In January 1998, the Registrant entered into an agreement with LMU &
Company (LMU).  As partial consideration for LMU's services under the
agreement, the Registrant granted an option to purchase 180,001 shares of
the Registrant's common stock for a period of five years at an exercise
price of $2.80 per share.  The shares are fully vested. The Registrant
claims the exemption from registration provided by Section 4(2) of the 1933
Act for this transaction.  No broker/dealers were involved in the sale and
no commissions were paid. The option certificate was impressed with a
restrictive legend advising that the shares represented by the certificate
may not be sold, transferred, pledged or hypothecated without having first
been registered or the availability of an exemption from registration
established.

In April 1998, the Registrant entered into an agreement with Western Center
for Clinical Studies (Western).  As partial consideration for Western's
services under the agreement, the Registrant granted an option to purchase
450,000 shares of the Registrant's common stock at an exercise price of
$1.50 per share, of which 75,000 are vested.  The remaining shares vest as
follows:  90,000 shares upon completion of the first Phase III trial,
110,000 upon completion of the second Phase III trial; and, 175,000 upon
the approval of a New Drug Application to the Food and Drug Administration.
The Registrant claims the exemption from registration provided by Section
4(2) of the 1933 Act for this transaction.  No broker/dealers were involved
in the sale and no commissions were paid. The option certificate was
impressed with a restrictive legend advising that the shares represented by
the certificate may not be sold, transferred, pledged or hypothecated
without having first been registered or the availability of an exemption
from registration established. The options expire five years from the dates
they become exercisable.

     The offers and sales were made in reliance upon the exemption from
registration provided by Section 4(2) of the 1933 Act and/or Regulation D
and Rule 506 adopted thereunder.  Based upon written representations made
by each of the purchasers, the Registrant believes that all were Accredited
Investors as that term is defined in Rule 501 of Regulation D.
Broker/dealers were involved in the sale of $797,500 of the Series B
Preferred Stock and approximately $79,750 were paid in commissions.  All
purchasers represented that they purchased the securities for investment,
and all certificates issued to the purchasers were impressed with a
restrictive legend advising that the shares represented by certificates may
not be sold, transferred, pledged or hypothecated without having first been
registered or the availability of an exemption from registration
established.  Stop transfer instructions have been placed against the
transfer of these certificates by the Registrant's Transfer Agent.

                                   IX.

     In August 1998, the Registrant granted options to each of its

first 100,000 shares represented by the Warrant will be adjusted down to
reflect a 25% discount from the average of the closing bid/ask price for
such period, exercisable as follows: 100,000 shares exercisable
immediately; an additional 100,000 shares shall become exercisable provided
that the Registrant has received $2 million in funding on or before May 15,

that the Registrant has received an additional $4 million in funding on or
before August 31, 1999, subject to ratable reductions to the extent that
any of the funding is not attributable to G&A.  The warrant expires March
22, 2004.  The issuance of the warrant to G&A was made in reliance upon the
exemption from registration provided by Section 4(2) of the 1933 Act.  No
broker/dealers were involved in the sale and no commissions were paid.  G&A
represented that G&A acquired the option for investment and not with a view
to distribution.  As of August 31, 1999, G&A has performed no services on
behalf of the Registrant and the Registrant disputes any obligation under

     The Company claims the exemption from registration provided by Section
4(2) of the Securities Act of 1933, as amended, and/or Rule 506 of
Regulation D adopted thereunder for the transactions described above.  All
of the purchasers were either known to the Registrant, or were referred to
the Registrant by a consultant to the Company. Based upon the written
representations made by the purchasers and other information known to the
Registrant, the Registrant believes all of the purchasers were Accredited
Investors as that term is defined in Rule 501 of Regulation D.  All
purchasers represented that they purchased the securities for investment,
and all certificates issued to the purchasers were impressed with a
restrictive legend advising that the shares represented by certificates may
not be sold, transferred, pledged or hypothecated without having first been
registered or the availability of an exemption from registration
established.  Stop transfer instructions have been placed against the
transfer of these certificates by the Registrant's Transfer Agent.  No
brokers or dealers received compensation in connection with the sale of
these shares.

                                  XXX.

     In September 1999, as partial consideration for consulting services
the Registrant issued Neidiger Tucker Bruner Inc. a warrant to purchase up
to 101,680 shares of the Registrant's common stock, exercisable at $4.00
per share for five years.  The Registrant claims the exemption from
registration provided by Section 4(2) of the 1933 Act for this transaction.
No broker/dealers were involved in the sale and no commissions were paid.
The warrant certificate was impressed with a restrictive legend advising
that the shares represented by the certificate may not be sold,
transferred, pledged or hypothecated without having first been registered
or the availability of an exemption from registration established.

                                  XXXI.

     In November 1999, as partial consideration for consulting services,
the Registrant issued ATO Ram 2, Ltd. a warrant to purchase up to 30,000
shares of the Registrant's common stock, exercisable at $4.00 per share for
five years.  The Registrant claims the exemption from registration provided
by Section 4(2) of the 1933 Act for this transaction. No broker/dealers
were involved in the sale and no commissions were paid.  The warrant
certificate was impressed with a restrictive legend advising that the
shares represented by the certificate may not be sold, transferred, pledged
or hypothecated without having first been registered or the availability of
an exemption from registration established.

                                 XXXII.

     In November 1999, the Registrant granted an option to purchase 400,000
shares of the Registrant's common stock to Thomas G. Tachovsky, a Director,
President and Chief Executive Officer of the Registrant at an exercise
price of $5.00 per share.  The shares vest as follows: 100,000 shares upon
completion of the first Phase III trial; 150,000 shares upon submission of
the NDA; and, 150,000 shares upon approval of the NDA.  The options expire
five years from the dates they become exercisable.  The Registrant claims
the exemption from registration provided by Section 4(2) of the 1933 Act
for this transaction.  No broker/dealers were involved in the sale and no
commissions were paid. The option certificate was impressed with a
restrictive legend advising that the shares represented by the certificate
may not be sold, transferred, pledged or hypothecated without having first
been registered or the availability of an exemption from registration
established.

                                 XXXIII.

     As of September 1999, the holders of 15,000 shares of the Registrant's
Series B Preferred Stock converted their shares into 15,000 shares of the
Registrant's common stock. The issuance of the shares of common stock upon
the conversion is exempt from registration in that there was no sale of the
shares by the Registrant. Each holder of the Registrant's Series B
Preferred Stock represented that he received the shares for investment and
not with a view to distribution. All certificates were endorsed with a
legend restricting the sale or transfer of the securities except in
accordance with federal securities laws.  Stop transfer instructions have
been placed against the transfer of these certificates by the Registrant's
Transfer Agent.

Item 28.  Undertakings
          ------------

The undersigned Registrant will:

    (a)(1)    File, during any period in which it offers or sells
securities, a post-effective amendment to this registration statement to:
(i) include any prospectus required by Section 10(a)(3) of the Securities
Act; (ii) reflect in the prospectus any facts or events which, individually
or together, represent a fundamental change in the information in the
registration statement; and (iii) include any additional or changed
material information on the plan of distribution.

    (2)  For determining liability under the Securities Act, treat each
post-effective amendment as a new registration statement of the securities
offered, and the offering of the securities at that time to be the initial
bona fide offering.

    (3)  File a post-effective amendment to remove from registration any
of the securities that remain unsold at the end of the offering.

                                  II-28

<PAGE>

    The undersigned Registrant will provide to the Underwriters at the
closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the Underwriters
to permit prompt delivery to each purchaser.

    Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to directors, officers
and controlling persons of the Registrant pursuant to the foregoing
provisions, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore,
unenforceable.  In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in
the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the
securities being registered, the Registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to
a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                 OFFICES

     SECTION 1.1   PRINCIPAL OFFICE.  The principal office of the
corporation of the corporation shall be designated from time to time by the
corporation and may be within or outside of Colorado.  The corporation may
have such other offices, either within or outside of the State of Colorado
as the Board of Directors may designate, or as the business of the
corporation may require from time to time.

     SECTION 1.2  REGISTERED OFFICE.  The registered office of the
corporation, required by the Colorado Business Corporation Act to be

                              SHAREHOLDERS

     SECTION 2.1  ANNUAL MEETING.  The annual meeting of the shareholders
shall be held at such time on such day as shall be fixed by the Board of
Directors for the purpose of electing directors and for the transaction of
such other business as may come before the meeting.  If the day fixed for
the annual meeting shall be a legal holiday in the State of Colorado, such
meeting shall be held on the next succeeding business day.  If the election
of directors shall not be held on the day designated herein for any annual
meeting of the shareholders, or at any adjournment thereof, the Board of
Directors shall cause the election to be held at a special meeting of the
shareholders as soon thereafter as may be convenient.

     SECTION 2.2  SPECIAL MEETINGS.  Special meetings of the shareholders,
for any purpose or purposes, unless otherwise prescribed by statute, may be
called by the Chief Executive Officer or by the Board of Directors, and
shall be called by the Chief Executive Officer upon the receipt of one or
more written demands for a special meeting, stating the purpose or purposes
for which it is to be held, signed and dated by the holders of shares
representing at least ten percent of all the votes entitled to be cast on
any issue proposed to be considered at the meeting.

     SECTION 2.3 COURT ORDERED MEETINGS.  A shareholder may apply to the
district court in the county in Colorado where the corporation's principal
office is located or, if

<PAGE>

the corporation has no principal office in Colorado, to the district court
of the county in which the corporation's registered office is located to
seek an order that a shareholder meeting be held (i) if an annual meeting
was not held within six months after the close of the corporation's most
recently ended fiscal year or fifteen months after its last annual meeting,
whichever is earlier, or (ii) if a shareholder participated in a proper
call of or demand for a special meeting and notice of the special meeting
was not given within thirty days after the date of the call or the date of
the last of the demands necessary to require the calling of the meeting was
received by the corporation pursuant to the Colorado Business Corporation
Act, or the special meeting was not held in accordance with the notice.

     SECTION 2.4 PLACE OF MEETINGS.  The Board of Directors may designate
any place, either within or outside of the State of Colorado, as the place
of meeting for any annual meeting or for any special meeting called by the
Board of Directors.  If no designation is made, or if a special meeting be
otherwise called, the place of meeting shall be the principal office of the
corporation.

     SECTION 2.5 NOTICE OF MEETING.  Written notice stating the place, day
and hour of the meeting of shareholders shall be delivered not less than
ten nor more than sixty days before the date of the meeting, except that
(i) if the number of authorized shares is to be increased, at least thirty
days' notice shall be given, or (ii) any other longer notice period is
required by the Colorado Business Corporation Act.  Notice of a special
meeting shall include a description of the purpose or purposes of the
meeting.  Notice of an annual meeting need not include a description of the
purpose or purposes of the meeting except the purpose or purposes shall be
stated with respect to (i) an amendment to the Articles of Incorporation of
the corporation, (ii) a merger or share exchange in which the corporation
is a party and, with respect to a share exchange, in which the
corporation's shares will be acquired, (iii) a sale, lease, exchange or
other disposition, other than in the usual and regular course of business,
of all or substantially all of the property of the corporation or of
another entity which this corporation controls, in each case with or
without the goodwill, (iv) a dissolution of the corporation, or (v) any
other purpose for which a statement of purpose is required by the Colorado
Business Corporation Act.  Notice shall be given personally or by mail,
private carrier, telegraph, teletype, electronically transmitted facsimile
or other form of wire or wireless communication, by or at the direction of
the Chief Executive Officer, or the Secretary, or the officer or other
persons calling the meeting, to each shareholder entitled to vote at such
meeting.  If mailed and in a comprehensible form, such notice shall be
deemed to be delivered when deposited in the United States mail, addressed
to the shareholder at his or her address as it appears on the stock
transfer books of the corporation, with postage thereon prepaid.  If notice
is given other than by mail, and provided such notice is in a
comprehensible form, the notice is given and effective on the date received
by the shareholder.

     No notice need be sent to any shareholder if three successive notices
mailed to the last known address of such shareholder have been returned as
undeliverable until such time as another address for such shareholder is
made known to the corporation by such shareholder.  In

                                   -2-

<PAGE>

order to be entitled to receive notice of any meeting, a shareholder shall
advise the corporation in writing of any change in such shareholder's
mailing address as shown on the corporation's books and records.

     When a meeting is adjourned to another date, time or place, notice
need not be given of the new date, time or place if the new date, time or
place of such meeting is announced before adjournment at the meeting at
which the adjournment is taken.  At the adjourned meeting the corporation
may transact any business which may have been transacted at the original
meeting.  If the adjournment is for more than 120 days, or if a new record
date is fixed for the adjourned meeting, a new notice of the adjourned
meeting shall be given to each shareholder of record entitled to vote at
the meeting as of the new record date.

     SECTION 2.6 MEETING OF ALL SHAREHOLDERS.  If all of the shareholders
shall meet at any time and place, either within or outside of the State of
Colorado, and consent in writing to the holding of a meeting at such time
and place, such meeting shall be valid without call or notice, and at such
meeting any shareholder action may be taken.

     SECTION 2.7 CLOSING OF TRANSFER BOOKS OR FIXING OF RECORD DATE.  For
the purpose of determining shareholders entitled to (i) notice of or to
vote at any meeting of shareholders or any adjournment thereof, (ii) to
receive distributions or share dividends, (iii) demand a special meeting,
or (iv) in order to make a determination of shareholders for any other
proper purpose, the Board of Directors of the corporation may provide that
the share transfer books shall be closed for a stated period but not to
exceed, in any case, seventy days.  If the share transfer books shall be
closed for the purpose of determining shareholders entitled to notice of or
to vote at a meeting of shareholders, such books shall be closed for at
least ten days immediately preceding such meeting.  In lieu of closing the
share transfer books, the Board of Directors may fix in advance a date as
the record date for any such determination of shareholders, such date in
any case to be not more than seventy days and, in case of a meeting of
shareholders, not less than ten days prior to the date on which the
particular action, requiring such determination of shareholders, is to be
taken.  If the share transfer books are not closed and no record date is
fixed for the determination of shareholders entitled to notice of or to
vote at a meeting of shareholders, or shareholders entitled to receive
payment of a distribution, the date on which notice of the meeting is
mailed or the date on which the resolution of the Board of Directors
declaring such distribution is adopted, as the case may be, shall be the
record date for such determination of shareholders.  When a determination
of shareholders entitled to vote at any meeting of shareholders has been
made as provided in this section, such determination shall apply to any
adjournment thereof, unless the meeting is adjourned to a date more than
one hundred twenty days after the date fixed for the original meeting, in
which case the Board of Directors shall make a new determination as
provided in this section.

     SECTION 2.8 VOTING LISTS.  The officer or agent having charge of the
stock transfer books for shares of the corporation shall make, at the
earlier of ten days before such

                                   -3-

<PAGE>

meeting of shareholders or two business days after notice of the meeting,
a complete list of the shareholders entitled to vote at each meeting of
shareholders or any adjournment thereof.  The list shall be arranged by
voting groups and within each voting group by class or series of shares,
shall be arranged in alphabetical order, within each class or series, and
shall show the address of and the number of shares of each class or series
held by each shareholder.  For the period beginning the earlier of ten days
prior to such meeting or two business days after notice of the meeting is
given and continuing through the meeting and any adjournment thereof, this
list shall be kept on file at the principal office of the corporation, or
at a place (which shall be identified in the notice) in the city where the
meeting will be held.  Such list shall be available for inspection on
written demand by any shareholder (including for the purpose of this
Section any holder of voting trust certificates) or his or her agent or
attorney during regular business hours and during the period available for
inspection.  The original stock transfer books shall be prima facie
evidence as to the shareholders entitled to examine such list or to vote at
any meeting of shareholders.

     Any shareholder, his or her agent or attorney, may copy the list
during regular business hours and during the period it is available for
inspection, provided (i) the shareholder has been a shareholder for at
least three months immediately preceding the demand or is a shareholder of
at least five percent of all of the outstanding shares of any class of
shares as of the date of the demand, (ii) the demand is made in good faith
and for a purpose reasonably related to the demanding shareholder's
interest as a shareholder, (iii) the shareholder describes with reasonable
particularity the purpose and the list the shareholder desires to inspect,
(iv) the list is directly connected with the described purpose; and (v) the
shareholder pays a reasonable charge covering the cost of labor and
material for such copies.

     SECTION 2.9 QUORUM.  One-third of the votes entitled to be cast on the
matter by a voting group, represented in person or by proxy, constitutes a
quorum of that voting group for the action on the matter.  If no specific
voting group is designated in the Articles of Incorporation or under the
Colorado Business Corporation Act for a particular matter, all outstanding
shares of the corporation entitled to vote, represented in person or by
proxy, shall constitute a voting group.  In the absence of a quorum at any
such meeting, a majority of the shares so represented may adjourn the
meeting from time to time for a period not to exceed one hundred twenty
days without further notice.  However, if the adjournment is for more than
one hundred twenty days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each shareholder of record entitled to vote at the meeting.

     At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been
transacted at the meeting as originally noticed.  The shareholders present
at a duly organized meeting may continue to transact business until
adjournment, notwithstanding the withdrawal during such meeting of that
number of shareholders whose absence would cause there to be less than a
quorum.

                                   -4-

<PAGE>

     SECTION 2.10 MANNER OF ACTING.  If a quorum is present, an action is
approved if the votes cast within the voting group favoring the action
exceeds the votes cast against the action, and the action so approved shall
be the act of the shareholders, unless the vote of a greater proportion or
number or voting by groups or classes is otherwise required by the Colorado
Business Corporation Act or by the Articles of Incorporation or these
Bylaws.

     SECTION 2.11 PROXIES.  At all meetings of shareholders, a shareholder
may vote by proxy by signing an appointment form or similar writing, either
personally or by his or her duly authorized attorney-in-fact.  A
shareholder may also appoint a proxy by transmitting or authorizing the
transmission of a telegram, teletype, or other electronic transmission
providing a written statement of the appointment to the proxy, a proxy
solicitor, proxy support service organization, or other person duly
authorized by the proxy to receive appointments as agent for the proxy, or
to the corporation.  The transmitted appointment shall set forth or be
transmitted with written evidence from which it can be determined that the
shareholder transmitted or authorized the transmission of the appointment.
The proxy appointment form or similar writing shall be filed with the
Secretary of the corporation before or at the time of the meeting.  The
appointment of a proxy is effective when received by the corporation and is
valid for eleven months unless a different period is expressly provided in
the appointment form or similar writing.

     Any complete copy, including an electronically transmitted facsimile,
of an appointment of a proxy may be substituted for or used in lieu of the
original appointment for any purpose for which the original appointment
could be used.

     Revocation of a proxy does not affect the right of the corporation to
accept the proxy's authority unless (i) the corporation had notice that the
appointment was coupled with an interest and notice that such interest is
extinguished is received by the Secretary or other officer or agent
authorized to tabulate votes before the proxy exercises his or her
authority under the appointment, or (ii) other notice of the revocation of
the appointment is received by the Secretary or other officer or agent
authorized to tabulate votes before the proxy exercises his or her
authority under the appointment.  Other notice of revocation may, in the
discretion of the corporation, be deemed to include the appearance at a
shareholders' meeting of the shareholder who granted the proxy and his or
her voting in person on any matter subject to a vote at such meeting.

     The death or incapacity of the shareholder appointing a proxy does not
affect the right of the corporation to accept the proxy's authority unless
notice of the death or incapacity is received by the Secretary or other
officer or agent authorized to tabulate votes before the proxy exercises
his or her authority under the appointment.

     The corporation shall not be required to recognize an appointment made
irrevocably if it has received a writing revoking the appointment signed by
the shareholder (including a shareholder who is a successor to the
shareholder who granted the proxy) either personally or by

                                   -5-

<PAGE>

his or her attorney-in-fact, notwithstanding that the revocation may be a
breach of an obligation of the shareholder to another person not to revoke
the appointment.

     SECTION 2.12 VOTING OF SHARES.  Unless otherwise provided by these
Bylaws or the Articles of Incorporation, each outstanding share entitled to
vote shall be entitled to one vote upon each matter submitted to a vote at
a meeting of shareholders, and each fractional share shall be entitled to
a corresponding fractional vote on each such matter.  Only shares are
entitled to vote.

     SECTION 2.13 VOTING OF SHARES BY CERTAIN SHAREHOLDERS.  If the name on
a vote, consent, waiver, proxy appointment, or proxy appointment revocation
corresponds to the name of a shareholder, the corporation, if acting in
good faith, is entitled to accept the vote, consent, waiver, proxy
appointment or proxy appointment revocation and give it effect as the act
of the shareholder.

     If the name signed on a vote, consent, waiver, proxy appointment or
proxy appointment revocation does not correspond to the name of a
shareholder, the corporation, if acting in good faith, is nevertheless
entitled to accept the vote, consent, waiver, proxy appointment or proxy
appointment revocation and to give it effect as the act of the shareholder
if:

     (i)  the shareholder is an entity and the name signed purports to be
that of an officer or agent of the entity;

     (ii) the name signed purports to be that of an administrator,
executor, guardian or conservator representing the shareholder and, if the
corporation requests, evidence of fiduciary status acceptable to the
corporation has been presented with respect to the vote, consent, waiver,
proxy appointment or proxy appointment revocation;

     (iii) the name signed purports to be that of a receiver or trustee in
bankruptcy of the shareholder and, if the corporation requests, evidence of
this status acceptable to the corporation has been presented with respect
to the vote, consent, waiver, proxy appointment or proxy appointment
revocation;

     (iv) the name signed purports to be that of a pledgee, beneficial
owner or attorney-in-fact of the shareholder and, if the corporation
requests, evidence acceptable to the corporation of the signatory's
authority to sign for the shareholder has been presented with respect to
the vote, consent, waiver, proxy appointment or proxy appointment
revocation;

     (v) two or more persons are the shareholder as co-tenants or
fiduciaries and the name signed purports to be the name of at least one of
the co-tenants or fiduciaries, and the person signing appears to be acting
on behalf of all the co-tenants or fiduciaries; or

                                   -6-

<PAGE>

     (vi) the acceptance of the vote, consent, waiver, proxy appointment or
proxy appointment revocation is otherwise proper under rules established by
the corporation that are not inconsistent with this Section 2.14.

     The corporation is entitled to reject a vote, consent, waiver, proxy
appointment or proxy appointment revocation if the Secretary or other
officer or agent authorized to tabulate votes, acting in good faith, has
reasonable basis for doubt about the validity of the signature on it or
about the signatory's authority to sign for the shareholder.

     Neither the corporation nor any of its directors, officers, employees
or agents who accepts or rejects a vote, consent, waiver, proxy appointment
or proxy appointment revocation in good faith and in accordance with the
standards of this Section is liable in damages for the consequences of the
acceptance or rejection.

     Redeemable shares are not entitled to be voted after notice of
redemption is mailed to the holders and a sum sufficient to redeem the
shares has been deposited with a bank, trust company or other financial
institution under an irrevocable obligation to pay the holders of the
redemption price on surrender of the shares.

     SECTION 2.14 ACTION BY SHAREHOLDERS WITHOUT A MEETING.  Unless the
Articles of Incorporation or these Bylaws provide otherwise, any action
required or permitted to be taken at a meeting of shareholders may be taken
without a meeting if the action is evidenced by one or more written
consents describing the action taken, signed by each shareholder entitled
to vote and delivered to the Secretary of the corporation for inclusion in
the minutes or for filing with the corporate records.  Action taken by
consent is effective as of the date the written consent is received by the
corporation unless the  writings specify a different effective date, in
which case such specified date shall be the effective date for such action.
If any shareholder revokes his or her consent as provided for herein prior
to what otherwise would be the effective date, the action proposed in the
consent shall be invalid.

     Any such writing may be received by the corporation by electronically
transmitted facsimile or other form of wire or wireless communication
providing the corporation with a complete copy thereof, including a copy of
the signature thereto.  The shareholder so transmitting such a writing
shall furnish an original of such writing to the corporation for the
permanent record of the corporation, but the failure of the corporation to
receive for record such original writing shall not affect the action so
taken.  In addition, such writings shall be deemed to be received by the
corporation if such writings are received by an officer or director of the
corporation, or an attorney representing the corporation, wherever such
persons may be found.

     The record date for determining shareholders entitled to take action
without a meeting shall be the date the corporation first receives a
writing upon which the action is taken.

                                   -7-

<PAGE>

     Any shareholder who has signed a writing describing and consenting to
action taken pursuant to this Section 2.14 may revoke such consent by a
writing signed and dated by the shareholder describing the action and
stating that the shareholder's prior consent thereto is revoked, if such
writing is received by the corporation prior to the date the last writing
necessary to effect the action is received by the corporation.

     SECTION 2.15 VOTING BY BALLOT.  Voting on any question or in any
election may be by voice vote unless the presiding officer shall order or
any shareholder shall demand that voting be by ballot.

     SECTION 2.16 NO CUMULATIVE VOTING.  No shareholder shall be permitted
to cumulate his or her votes in the election for directors or otherwise.

     SECTION 2.17 WAIVER OF NOTICE.  When any notice is required to be
given to any shareholder, a waiver thereof in writing signed by the person
entitled to such notice, whether before, at, or after the time stated
therein, shall be equivalent to the giving of such notice.  Such waiver
shall be delivered to the corporation for filing with the corporate
records.

     The attendance of a shareholder at any meeting shall constitute a
waiver of notice, waiver of objection to defective notice of such meeting,
or a waiver of objection to the consideration of a particular matter at the
shareholder meeting unless the shareholder, at the beginning of the
meeting, objects to the holding of the meeting, the transaction of business
at the meeting, or the consideration of a particular matter at the time it
is presented at the meeting.

                           BOARD OF DIRECTORS

shall perform his or her duties as a director, including his or her duties
as a member of any committee of the board upon which he or she may serve,

interests of the corporation, and with such care as an ordinarily prudent
person in a like position would use under similar circumstances.  In
performing his or her duties, a director shall be entitled to rely on
information, opinions, reports, or statements, including financial
statements and other financial data, in each case prepared or presented by
persons and groups listed in paragraphs (a), (b), and (c) of this Section

or she has knowledge concerning the matter in question

                                   -8-

that would cause such reliance to be unwarranted.  A person who so performs
his or her duties shall not have any liability by reason of being or having
been a director of the corporation.

     Those persons and groups on whose information, opinions, reports, and
statements a director is entitled to rely upon are:

     (a)  One or more officers or employees of the corporation whom the
director reasonably believes to be reliable and competent in the matters
presented;

     (b)  Counsel, public accountants, or other persons as to matters which
the director reasonably believes to be within such persons' professional or
expert competence; or

     (c)  A committee of the board upon which he or she does not serve,
duly designated in accordance with the provision of the Articles of
Incorporation or these Bylaws, as to matters within its designated
authority, which committee the director reasonably believes to merit
confidence.

     SECTION 3.3 NUMBER, TENURE AND QUALIFICATIONS.  The number of
directors of the corporation shall be not less than three (3) nor more than
seven (7) directors, and the number of directors shall be fixed within this

Directors need not be residents of the State of Colorado or shareholders of
the corporation.

     SECTION 3.4 REGULAR MEETINGS.  A regular meeting of the Board of
Directors shall be held without notice other than this bylaw immediately
after, and at the same place as, the annual meeting of shareholders.  The
Board of Directors may provide, by resolution, the time and place, either
within or without the State of Colorado, for the holding of additional
regular meetings without notice other than such resolution.

     SECTION 3.5 SPECIAL MEETINGS.  Special meetings of the Board of
Directors may be called by or at the request of the Chairman of the Board,

<PAGE>

     By personal delivery, facsimile or telegram at least twenty-four hours
prior to the meeting to the business address of each director, or in the
event such notice is given on a Saturday, Sunday or holiday, to the
residence address of each director.

     If mailed, such notice shall be deemed to be delivered when deposited
in the United States mail, so addressed, with postage thereon prepaid.  If
notice is given by facsimile, such notice shall be deemed to be delivered
when a confirmation of the transmission of the facsimile has been received
by the sender.  If notice is given by telegram, such notice shall be deemed
to be delivered when the telegram is delivered to the telegraph company.

     Any director may waive notice of any meeting before or after the time
and date of the meeting stated in the notice.  The waiver shall be in
writing and signed by the director entitled to the notice.  The attendance
of a director at any meeting shall constitute a waiver of notice of such
meeting, except where a director attends a meeting for the express purpose
of objecting to the transaction of any business because the meeting is not
lawfully called or convened.  Neither the business to be transacted at, nor
the purpose of, any regular or special meeting of the Board of Directors
need be specified in the notice or waiver of notice of such meeting.

     SECTION 3.7 QUORUM.  A majority of the number of directors fixed by or
pursuant to Section 3.3 of this Article III, or if no such number is fixed,
a majority of the number of directors in office immediately before the

present at a meeting, a majority of the directors present may adjourn the
meeting from time to time without further notice.

     SECTION 3.8 MANNER OF ACTING.  Except as otherwise required by the
Colorado Business Corporation Act or by the Articles of Incorporation, the
act of the majority of the directors present at a meeting at which a quorum
is present when a vote is taken shall be the act of the Board of Directors.

the Articles of Incorporation or these Bylaws provide otherwise, any action
required or permitted to be taken at a meeting of the Board of Directors or
any committee designated by said board may be taken without a meeting if
the action is evidenced by one or more written consents describing the
action taken, signed by each director or committee member, and delivered to
the Secretary for inclusion in the minutes or for filing with the corporate
records.  Action taken under this section is effective when all directors
or committee members have signed the consent, unless the consent specifies
a different effective date.  Such consent has the same force and effect as
an unanimous vote of the directors or committee members and may be stated
as such in any document.

Board of Directors or any committee designated by such Board may
participate in a meeting of the Board of Directors or committee by means of
telephone conference or similar communications equipment by which all
persons participating in the meeting can hear each other at the same time.
Such participation shall constitute presence in person at the meeting.

     SECTION 3.11 VACANCIES.  Any vacancy occurring in the Board of
Directors may be filled by the affirmative vote of a majority of the
shareholders or the Board of Directors.  If the directors remaining in
office constitute fewer than a quorum of the board, the directors may fill
the vacancy by the affirmative vote of a majority of all the directors
remaining in office.

     If elected by the directors, the director filling the vacancy shall
hold office until the next annual shareholders' meeting at which directors
are elected.  If elected by the shareholders, the director filling the
vacancy shall hold office for the unexpired term of his or her predecessor
in office; except that, if the director's predecessor was elected by the
directors to fill a vacancy, the director elected by the shareholders shall
hold the office for the unexpired term of the last predecessor elected by
the shareholders.

     If the vacant office was held by a director elected by a voting group
of shareholders, only the holders of shares of that voting group are
entitled to vote to fill the vacancy if it is filled by the shareholders,
and, if one or more of the remaining directors were elected by the same
voting group, only such directors so elected by the same voting group are
entitled to vote to fill the vacancy if it is filled by the directors.

     SECTION 3.12 RESIGNATION.  Any director of the corporation may resign
at any time by giving written notice to the Secretary of the corporation.
The resignation of any director shall take effect upon receipt of notice
thereof or at such later time as shall be specified in such notice; and,
unless otherwise specified therein, the acceptance of such resignation
shall not be necessary to make it effective.  When one or more directors
shall resign from the board, effective at a future date, a majority of the
directors then in office, including those who have so resigned, shall have
power to fill such vacancy or vacancies, the vote thereon to take effect
when such resignation or resignations shall become effective.

     SECTION 3.15 COMPENSATION.  By resolution of the Board of Directors
and irrespective of any personal interest of any of the directors, each
director may be paid his or her expenses, if any, of attendance at each
meeting of the Board of Directors, and may be paid a stated salary as
director or a fixed sum for attendance at each meeting of the Board of
Directors or both.  No such payment shall preclude any director from
serving the corporation in any other capacity and receiving compensation
therefor.

     SECTION 3.16 PRESUMPTION OF ASSENT.  A director of the corporation who
is present at a meeting of the Board of Directors or committee of the board
at which action on any corporate matter is taken shall be presumed to have
assented to the action taken unless (i) the director objects at the
beginning of the meeting, or promptly upon his or her arrival, to the
holding of the meeting or the transaction of business at the meeting and
does not thereafter vote for or assent to any action taken at the meeting,
(ii) the director contemporaneously requests that his or her dissent or
abstention as to any specific action taken be entered in the minutes of the
meeting, or (iii) the director causes written notice of his or her dissent
or abstention as to any specific action to be received by the presiding
officer or the meeting before its adjournment or by the corporation
promptly after the adjournment of the meeting.  A director may dissent to
a specific action at a meeting, while assenting to others.  The right to
dissent to a specific action taken at a meeting of the Board of Directors
or a committee of the board shall not be available to a director who voted
in favor of such action.

     SECTION 6.1 REGULATION.  The Board of Directors may make such rules
and regulations as it may deem appropriate concerning the issuance,
transfer and registration of certificates for shares of the corporation,
including the appointment of transfer agents and registrars.

     SECTION 6.2 SHARES WITHOUT CERTIFICATES.  Unless otherwise provided by
the Articles of Incorporation or these Bylaws, the Board of Directors may
authorize the issuance of any of its classes or series of shares without
certificates.  Such authorization shall not affect shares already

     Within a reasonable time following the issue or transfer of shares
without certificates, the corporation shall send the shareholder a complete
written statement of the information required on certificates by the
Colorado Business Corporation Act.

     SECTION 6.3 CERTIFICATES FOR SHARES.  If shares of the corporation are
represented by certificates, the certificates shall be respectively
numbered serially for each class of shares, or series thereof, as they are
issued, and shall be signed by an officer of the corporation authorized by
these Bylaws or a resolution of the Board of Directors; provided that such
signatures may be facsimile.  Each certificate shall state the name of the
corporation, the fact that the corporation is organized or incorporated
under the laws of the State of Colorado, the name of the person to whom
issued, the date of issue, the class (or series of any class), the number
of shares represented thereby.  A statement of the designations,
preferences, qualifications, limitations, restrictions and special or
relative rights of the shares of each class shall be set forth in full or
summarized on the face or back of the certificates which the corporation
shall issue, or in lieu

                                  -16-

<PAGE>

scrip to have terms and conditions specified by the Board of Directors.

except as herein provided with respect to lost, stolen or destroyed
certificates.

shares shall not be issued until the shares represented thereby are fully
paid.  The Board of Directors may authorize the issuance of shares for
consideration consisting of any tangible or intangible property or benefit
to the corporation, including cash, promissory notes, services performed or
other securities of the corporation.  Future services shall not constitute
payment or partial payment for shares of the corporation.  The promissory
note of a subscriber or an affiliate of a subscriber shall not constitute
payment or partial payment for shares of the corporation unless the note is
negotiable, recourse and is secured by collateral, other than the shares
being purchased, having a fair market value of at least equal to the
principal amount of the note.

     SECTION 6.6 LOST, STOLEN OR DESTROYED CERTIFICATES.  Any shareholder
claiming that his or her certificate for shares is lost, stolen or

same with the Secretary of the corporation, accompanied by a signed
application for a new certificate.  Thereupon, and upon the giving of a
satisfactory bond of indemnity to the corporation not exceeding an amount
double the value of the shares as represented by such certificate (the
necessity for such bond and the amount required to be determined by the
President and Treasurer of the corporation), a new certificate may be
issued of the same tenor and representing the same number, class and series
of shares as were represented by the certificate alleged to be lost, stolen
or destroyed.

     SECTION 6.7 TRANSFER OF SHARES.  Subject to the terms of any
shareholder agreement relating to the transfer of shares or other transfer
restrictions contained in the Articles of Incorporation or authorized
therein, shares of the corporation shall be transferable on the books of

authorized attorney, upon the surrender and cancellation of a certificate
or certificates for a like number of shares.  Upon presentation and
surrender of a certificate for shares properly endorsed and payment of all
taxes

                                  -17-

therefor, the transferee shall be entitled to a new certificate or
certificates in lieu thereof.  As against the corporation, a transfer of
shares can be made only on the books of the corporation and in the manner
hereinabove provided, and the corporation shall be entitled to treat the
holder of record of any share as the owner thereof and shall not be bound
to recognize any equitable or other claim to or interest in such share on
the part of any other person, whether or not it shall have express or other
notice thereof, except as expressly provided by the Colorado Business
Corporation Act.

                      UNIFORMITY OF INTERPRETATION
                            AND SEVERABILITY


     These Bylaws shall be so interpreted and construed as to conform to
the Articles of Incorporation, as amended, and the statutes of the State of
Colorado or of any other state in which conformity may become necessary by
reason of the qualification of the corporation to do business in such
foreign state, and where conflict between these Bylaws and the Articles of
Incorporation, as amended, or a statute has arisen or shall arise, the
Bylaws shall be considered to be modified to the extent, but only to the
extent, conformity shall require.  If any Bylaw provision or its
application shall be deemed invalid by reason of the said nonconformity,
the remainder of the Bylaws shall remain operable in that the provisions
set forth in the Bylaws are severable.

                               ARTICLE XII

                            EMERGENCY BYLAWS

     The Emergency Bylaws provided in this Article XII shall be operative

resulting from a catastrophic event causing a quorum of directors to be not
readily obtained as a result thereof, notwithstanding any different
provision in the preceding articles of the Bylaws or in the Articles of

     This Warrant Certificate certifies that ___________________, or
registered assigns ("the Warrant Holder"), is the registered owner of the
above indicated number of  Common Stock Purchase Warrants (the "Warrants")
expiring on __________________, 2005 (the "Expiration Date").  One Warrant

from Entropin, Inc., a Colorado corporation (the "Company"), at a purchase
price of $___________ (the "Exercise Price"), commencing on ____________,
2000, and terminating on the Expiration Date ("Exercise Period"), upon
surrender of this Warrant Certificate with the exercise form hereon duly
completed and executed with payment of the Exercise Price at the office of
Corporate Stock Transfer, Inc. (the "Warrant Agent"), but only subject to
the conditions set forth herein and in a Warrant Agreement dated as of
___________, 2000 (the "Warrant Agreement") between the Company and the
Warrant Agent.  The Exercise Price, the number of shares purchasable upon
exercise of each Warrant, the number of Warrants outstanding and the
Expiration Date are subject to adjustments upon the occurrence of certain
events.  The Warrant Holder may exercise all or any number of Warrants.
Reference hereby is made to the provisions on the reverse side of this
Warrant Certificate and to the provisions of the Warrant Agreement, all of
which are incorporated by reference in and made a part of this Warrant
Certificate and shall for all purposes have the same effect as though fully
set forth at this place.

     Upon due presentment for transfer of this Warrant Certificate at the
office of the Warrant Agent, a new Warrant Certificate or Warrant
Certificates of like tenor and evidencing in the aggregate a like number of
Warrants, subject to any adjustments made in accordance with the provisions
of the Warrant Agreement, shall be issued to the transferee in exchange for
this Warrant Certificate, subject to the limitations provided in the
Warrant Agreement, upon payment of $_________ per Warrant Certificate and
any tax or governmental charge imposed in connection with such transfer.

     The Warrant Holder of the Warrants evidenced by this Warrant
Certificate may exercise all or any whole number of such Warrants during
the period and in the manner stated hereon.  The Exercise Price shall be
payable in lawful money of the United States of America and in cash or by
certified or bank cashier's check or bank draft payable to the order of the
Company.  If upon exercise

<PAGE>

of any Warrants evidenced by this Warrant Certificate the number of
Warrants exercised shall be less than the total number of Warrants so
evidenced, there shall be issued to the Warrant Holder a new Warrant
Certificate evidencing the number of Warrants not so exercised.

     Subject to the following paragraph, no Warrant may be exercised after
5:00 p.m. Mountain Time on the Expiration Date and any Warrant not
exercised by such time shall become void, unless extended by the Company.

     The Warrants are subject to redemption by the Company at $.25 per
Warrant, no earlier than ____________, 2001, at any time prior to their
expiration, or not less than 30 days' prior written notice to the holders
of Warrants, provided that the daily trading price per share of Common
Stock has been at least $___________ (200% of the Warrant exercise price)
for a period of at least 10 consecutive trading days ending within 5 days
prior to the date upon which the notice of redemption is given.  The
Warrant Holders shall have the right to exercise the Warrants held by them
before the date specified in the redemption notice.  Upon expiration of
such period, all rights of the Warrant Holders shall terminate, other than
the rights to receive the redemption price, without interest, and the right
to receive the redemption price shall itself expire on the Warrant
Expiration Date.

     This Warrant Certificate shall not be valid unless countersigned by
the Warrant Agent.

     IN WITNESS WHEREOF, the Company has caused this Warrant to be signed
by its President and by its Secretary, each by a facsimile of his/her
signature, and has caused a facsimile of its corporate seal to be imprinted

                     FORM OF REVERSE SIDE OF WARRANT

     This Warrant Certificate, when surrendered to the Warrant Agent at its
principal office by the Warrant Holder, in person or by attorney duly
authorized in writing, may be exchanged in the manner and subject to the
limitations provided in the Warrant Agreement, upon the payment of any tax
or other governmental charge imposed in connection with such exchange, for
another Warrant Certificate or Warrant Certificates of like tenor and
evidencing a like number of Warrants, subject to any adjustments made in
accordance with the provisions of the Warrant Agreement.

     The Company and the Warrant Agent may deem and treat the registered
holder hereof as the absolute owner of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by
anyone) for all proposes and neither the Company nor the Warrant Agent
shall be affected by any notice to the contrary.  No Warrant Holder, as
such, shall have any rights of a holder of the Common Stock of the Company,
either at law or at equity, and the rights of the Warrant holder, as such,
are limited to those rights expressly provided in the Warrant Agreement and
in the Warrant Certificate.

     Under the Warrant Agreement the Exercise Price is subject to
adjustment if the Company shall effect any stock split or stock combination
with respect to the Common Stock.  Any such adjustment of the Exercise
Price will also result in an adjustment of the number of shares of Common
Stock purchasable upon exercise of a Warrant or, if the Company should
elect, an adjustment of each outstanding Warrant into a different number of
Warrants.

     The Company shall not be required to issue fractions of Warrants upon
any such adjustment or to issue fractions of shares upon the exercise of
any Warrants upon any such adjustment, in accordance with the Warrant
Agreement.

     The Warrant Agreement is subject to amendment upon the approval of
holders of at least two-thirds of the outstanding Warrants as a group,
except that no such approval is required for the reduction of the Exercise
Price or extension of the Expiration Date.  No amendment shall accelerate
the Expiration Date or increase the Exercise Price without the approval of
all the holders of all outstanding Warrants.  A copy of the Warrant
Agreement will be available at all reasonable times at the office of the
Warrant Agent for inspection by any Warrant Holder.  As a condition of such
inspection, the Warrant Agent may require any Warrant Holder to submit the
Warrant Holder's Warrant Certificate for inspection.

IMPORTANT:  The Warrants represented by this Certificate may not be
exercised by a Warrant Holder unless at the time of exercise the underlying
shares of Common Stock are qualified for sale by registration or otherwise
in the state where the Warrant Holder resides or unless the issuance of the
shares of Common Stock would be exempt under the applicable state
securities laws.  Further, a registration statement under the Securities
Act of 1933, as amended, covering the issuance of shares of Common Stock
upon the exercise of this Warrant must be in effect and current at the time
of exercise unless the issuance of shares of Common Stock upon any exercise
is exempt from the registration requirements of the Securities Act of 1933.
Unless such registration statement is in effect and current at the time of
exercise, or unless such an exemption is available the Company may decline
to permit the exercise of this Warrant.

RE:  ENTROPIN, INC.
     REGISTRATION STATEMENT ON FORM SB-2

Gentlemen:

     We have acted as counsel to Entropin, Inc., a Colorado corporation
(the "Company"), in connection with the preparation and filing with the
U.S. Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Act"), the Company's registration
statement on Form SB-2 (the "Registration Statement").  The Registration
Statement relates to the registration under the Act of:  (i) 2,500,000
shares of Common Stock (the "Shares"); (ii) 2,500,000 Warrants each to
purchase one share of Common Stock (the "Warrants"); and, (iii) and the
2,500,000 shares of Common Stock underlying the Warrants (the "Underlying
Shares").

     In rendering this opinion, we have reviewed the Registration
Statement, as well as a copy of the Company's articles of incorporation and
bylaws, each as amended to date.  We have also reviewed such documents and
such statutes, rules and judicial precedents as we have deemed necessary
for the opinions expressed herein.

     In rendering this opinion, we have assumed the genuineness of all
signatures, the legal capacity of natural persons, the authenticity of
documents submitted to us as originals, the conformity to original
documents of documents submitted to us as certified or photostatic copies,
and the authenticity of originals of such photostatic copies.

     Based upon and in reliance upon the foregoing, and subject to the
qualifications and limitations herein set forth, we are of the opinion that
the Shares and Warrants have been duly and validly authorized and issued,
and that the Underlying Shares, when issued for the consideration and in
the manner contemplated by the Registration Statement, will be validly
issued, fully paid and nonassessable.



Board of Directors
Entropin, Inc.
March 7, 2000

     The opinion set forth in this letter is limited by, subject to and
based on the following:

     1.   We are admitted to practice before the Bar of the State
          of Colorado and are not admitted to practice in any
          other jurisdiction.

     2.   The foregoing opinion is limited in all respects to the
          laws of the State of Colorado and applicable federal
          securities laws of the United States.

     We consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement.

     This opinion may not be used, circulated, quoted or otherwise referred
to for any other purpose without prior written consent and may not be
relied upon by any person or entity other than the Company and its
successors and assigns.  This opinion is based upon our knowledge of law
and facts as of this date.  We assume no duty to communicate to you with
respect to any matter which comes to our attention hereafter.

                              Very truly yours,



                              /s/ Brenman Bromberg & Tenenbaum, P.C.

Board of Directors
Entropin, Inc.

Dear Sirs:

This letter is being delivered to you in connection with further financing
obligations undertaken subsequent to the filing of the Form SB-2
Registration Statement (the "Registration Statement") filed by Entropin,
Inc., (the "Company") with the United States Securities and Exchange
Commission (the "SEC").  Since the Registration Statement was declared
effective by the SEC on August 18, 1998 (the "Effective Date"), the
Company's Common Stock shares registered thereby (including those of the
undersigned) have been free-trading without restriction or limitation.


The Company has advised the undersigned that securities underwriters and
other sources of potential future funding of the Company may require that
the undersigned and other shareholders set forth below agree to extend the
term of the previous Agreement Among Shareholders dated June 29, 1998.
The Company has requested the undersigned to agree thereto.

Therefore, in consideration of each of the shareholders set forth below
entering into this Agreement, the undersigned agrees not to offer, sell or
contract to sell or otherwise dispose of, directly or indirectly, or
announce an offering of, any shares of the Company's Common Stock owned by
the undersigned (or any securities convertible into, or exchangeable for,
shares of the Company's Common Stock) during the period ending March 15, 2000.

In the event that, during the term of this Agreement, the Company permits
the sale or other disposition of a portion of shares (a "Permitted
Disposition") by the undersigned shareholders, it shall do so on a PRO RATA
basis.  Since the shares are being registered in the Registration
Statement, the shares are free-trading upon a Permitted Disposition
during the term of this Agreement, or a disposition after the expiration of
this Agreement, provided that the Registration Statement is current at the
time of a disposition.  The Company hereby undertakes to use its best
efforts to keep the Registration Statement current.

Yours very truly,

provisions contained within the Agreement, as it relates to his work and
responsibilities on behalf of  DMR for Entropin.

     4.   SERVICES AND PAYMENT.  Services to be performed by DMR to
Entropin shall be on a project-by-project basis.  With respect to each
project, Entropin and DMR shall execute a written work order detailing the
work to be performed and the milestones therefor, up to and including a
completion date.  The work order shall specify the compensation to be paid
for the project and the payment terms therefor; which terms shall include
payment net 30 days from invoice subject to acceptance, and shall otherwise
be commercially reasonable, and usual and customary for transactions of
this type.

     5.   ARBITRATION.  Although Section 12.3 of the Agreement states that
arbitration shall be conducted in Los Angeles, California, and Section 13.4
of the Agreement states that arbitration shall be conducted in Las Vegas,
Nevada, any and all disputes arising under this Agreement shall be subject
to arbitration pursuant to the rules of the American Arbitration
Association and shall be conducted in Denver, Colorado.

     6.   RELATED PARTY TRANSACTION.  Subsequent to execution of the
Agreement, Wynn was appointed to the Board of Directors of Entropin.  He
has become the Scientific Advisor to Entropin and is acting as liaison to
the Board on behalf of the Scientific Advisory Board.  As a result of
serving in these capacities, the Agreement has subsequently become a
related party transaction between Entropin and Wynn.  Accordingly, the
Board has considered the fairness of the terms and conditions of the
Agreement and this Amendment thereto.  The Board has determined that the
terms and conditions are fair and reasonable, and at least as favorable as
obtainable from a third-party capable of performing the services under the
Agreement.

          involving moral turpitude, WCCS' habitual neglect of WCCS' duties
          under this Agreement or theft of Entropin property. Upon

          monies due for work actually performed and/or expenses actually

2.6  TERMINATION BY WCCS

     A.   MATERIAL BREACH.   WCCS shall have the right to immediately

("Suspension of the Term").  The Term may be suspended by WCCS pursuant to
Article 3.1.  If there is a Suspension of the Term, Entropin agrees WCCS

2.9  SURVIVAL.   Neither the expiration or termination of this Agreement

                               ARTICLE III
                              COMPENSATION

3.1  TOTAL STUDY COST.  The estimated total cost for the Services (the
"Total Study Cost") is detailed in APPENDIX D attached hereto and made a
part hereof.  Notwithstanding Article 3.3, the Total Study Cost shall not
exceed the estimate for any reason without the prior written approval of
Entropin.  Cost increases greater than 10% of the Total Study Cost will
require an amendment to this Agreement.  In the event the prior written
consent of Entropin is not obtained or an amendment to the Agreement has
not been executed, WCCS will suspend all Services prior to exceeding the
estimated Total Study Cost, unless such suspension would result in risks to
the Study Subjects.

3.2  TOTAL STUDY COST PAYMENT SCHEDULE.   The Total Study Cost shall be
payable in accordance with the terms of this Agreement and APPENDICES D AND
E attached hereto and made a part hereof.

3.3  ENTROPIN-REQUESTED CHANGES TO THE PROTOCOL AND/OR STUDY.     Entropin
reserves the right to request WCCS to perform reasonable, related services
("Additional Services") in addition to the services set forth in APPENDICES
A, C AND D.  Subject to the last sentence of this Article 3.3, in the event
Entropin does request WCCS in writing to perform Additional Services,
Entropin and WCCS shall mutually agree on the cost for such Additional
Services prior to WCCS being obligated to undertake such Additional
Services.  Any costs incurred by WCCS under this Article 3.3, which cause
the Total Study Cost to be exceeded without Entropin's prior written
approval, shall not be reimbursed.  Notwithstanding anything to the
contrary set forth in this Article 3.3, WCCS shall perform without any
increase in the Total Study Cost, Addional Services including, without
limitation, those services necessitated as a result of changes to the Study
and/or Protocol, provided that such Additional Services are, or would have
been, reasonably expected to be within the scope of the Study as determined
by industry standards.

                                    5

<PAGE>

3.4  REDUCTION IN THE TOTAL STUDY COST.     In the event any agreed upon
reduction in either the scope of the Study or amount of Services requested
by Entropin reduces the Total Study Cost such that the total amount
previously paid exceeds the reduced Total Study Cost, the difference shall
be returned to Entropin by WCCS in full at the end of the Term.

3.5  MONITORING/MEETING EXPENSE.  Entropin shall reimburse WCCS for all
monitoring/meeting expenses actually incurred by WCCS in accordance with
Entropin's Reimbursement Policy attached hereto as Appendix F and made part
hereof.  As a prerequisite to reimbursement under this Article, WCCS shall
maintain and have readily available appropriate documentation on file in
accordance with Entropin's Reimbursement Policy which may be audited at any
time upon request by Entropin.

3.6  ADDITIONAL POSTAGE.   Entropin shall be invoiced on a monthly basis
and at WCCS's net costs for all necessary next day mail and/or courier
services related to the administration of the Study.  For expedited
shipments, economy two-day delivery is the preferred method.  WCCS will use
discretion when shipping by Standard Overnight delivery and will use
Priority Overnight delivery only when absolutely necessary.

                               ARTICLE IV
                             CONFIDENTIALITY

Entropin, attached hereto as Appendix H and incorporated by reference
herein ("Non-Disclosure Agreement").  Pursuant to the terms of the Non-
Disclosure Agreement, WCCS will not disclose the confidential information

information directly or indirectly for the benefit of WCCS.

7.4  ADVERSE EVENT REPORTING.

     A.   WCCS AGREEMENTS.   WCCS will enter into an agreement with the CRO
          that the following adverse events will be reported to WCCS
          immediately by telephone from the investigator: (i) those events
          which are defined by the Protocol as "serious", including events
          which (a) result in death, severe or permanent disability,
          cancer, congenital anomaly, or overdose; (b) are considered life-
          threatening; and/or (c) which result in hospitalization or
          prolongs an existing hospitalization; and, (ii) those events
          which are defined by Protocol as "unexpected," meaning any event
          which is not identified in nature, severity, or frequency in the

          unfavorable and unintended sign (including an abnormal laboratory
          finding), symptom, or disease temporally associated with the use
          of the medicinal (investigational) product, whether or not
          related to the medicinal (investigational) product.

     C.   PATIENT TREATMENT BY INVESTIGATOR(S).   Any investigator, if
          properly qualified, shall have the right to provide reasonable
          and customary treatment to any Study Subject who exhibits
          symptoms of an adverse reaction.  Such properly qualified
          investigator shall advise WCCS in advance of such treatment,
          whenever reasonably possible, or as soon thereafter if prior
          notice is not possible.

     D.   PAYMENT OF COSTS.   If in the opinion of the investigator and
          WCCS, the Study Subject's reaction directly resulted from the use
          of the Study Drug, placebo provided in conjunction with the
          Study, if applicable, or other required procedures involved in
          the Study, then Entropin shall reimburse patients for all
          reasonable and customary costs associated with the diagnosis and
          treatment provided, to the extent such costs are not reimbursed
          by medical insurance of Study Subjects.  In the event that a
          suspected adverse reaction is not, in the opinion of the
          investigator and WCCS, Study related, Entropin shall provide
          reimbursement for diagnostic work-up costs only.  Entropin's
          obligation to pay the foregoing costs is limited to incidents when

                                    8

          law, accepted medical practice, the Protocol and any other
          written instructions, precautions, and/or indications furnished
          by or on behalf of Entropin; and (b) without negligence,
          recklessness, or willful misconduct or omission of the
          investigator or the Study Subjects.

          indemnify, defend and hold harmless WCCS, WCCS Agents, WCCS'
          affiliates and their respective officers, directors and employees

          actions or demands, including but not limited to reasonable
          attorneys' fees, costs of suit, judgments and settlements, which
          Indemnitee becomes legally obligated to pay on a claim made
          against Indemnitee by any party ("Loss") to the extent that such
          Loss (i) is a result of administration of the Study Drug; (ii)
          arises out of the activities or procedures carried out in the
          Services; or (iii) arises out any material violation of this

          governmental requirements.

     B.   CONDITIONS OF INDEMNITY OBLIGATIONS.  As condition precedent to
          indemnification under Article 12.1 (A), Indemnitee agrees to
          notify Entropin in writing within ten (10) days of Indemnitee
          becoming aware of any claim threatened, asserted, made, brought
          or instituted against it that could or may result in a Loss.
          Whenever the Indemnitee has information from which it may
          reasonably conclude that any incident of bodily injury, sickness,
          disease or death has occurred or will occur (an "Incident") to a
          Study Subject during the Study, Indemnitee shall immediately
          notify Entropin of all pertinent data

          assisting Entropin with respect to gathering information

          demands, including but not limited to reasonable attorneys' fees,

          omissions, and/or performance under this Agreement, to the extent
          such Loss is not indemnified by Entropin pursuant to Article
          12.1.  Notwithstanding anything to the contrary set forth in this

          directed WCCS and/or the CRO to engage certain investigator(s) to
          perform Services, WCCS shall be relieved of its indemnification
          obligations under this Article 12.2 (A) but only to the extent
          such Loss is a result of the acts and/or omissions of such
          investigator(s).

          defend and hold harmless Indemnitee from and against any loss,

          and settlements which Indemnitee becomes legally obligated to pay
          on a claim made against Indemnitee by any party ("Loss") to the
          extent such Loss results either directly or indirectly from any
          bodily injury, damage to or loss of any property incurred due to
          WCCS', its officers', directors', agents', or employees' or WCCS'
          Agent's (i) negligence or gross negligence or willful malfeasance
          or nonfeasance; (ii) willful malfeasance or nonfeasance; (iii)

Neidiger Tucker Brunner, Inc.
1675 Larimer Street, Suite 300
Denver, CO 80202

Gentlemen:

     Entropin, Inc., a Colorado corporation (the "Company"), hereby
confirms its agreement with Neidiger Tucker Brunner, Inc. ("NTB"), as
representative (the "Representative") of the several underwriters listed on
Schedule 1 annexed hereto (the "Underwriters"), as set forth below.

     The Company proposes to issue and sell to the Underwriters _________
shares of the Company's $.001 par value common stock (the "Common Stock").
The shares of Common Stock being sold by the Company are referred to as the
"Firm Shares."

     In addition, for the sole purpose of covering over-allotments from the
sale of the Firm Shares the Company proposes to grant to the Underwriters
an option to purchase an additional ______ shares of Common Stock (the
"Firm Option Shares" or the "Option Shares"), all as provided in Section
2(c) of this agreement (the "Agreement") and to issue to you the
Representative's Warrant (as defined in Section 2 hereof) to purchase
certain further additional shares of Common Stock.  The Firm Shares and the
Option Shares are collectively referred to herein as either the "Shares" or
the "Securities."

     1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company
represents and warrants to, and agrees with, the Underwriter that:

          (a)  A registration statement on Form SB-2  (File No. 333-_____),
with respect to the Securities and the Representative's Warrant Securities
(as hereinafter defined), including a prospectus subject to completion, has
been filed by the Company with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Act "),
and one or more amendments to that registration statement may have been so
filed. Copies of such registration statement and of each amendment
heretofore filed by the Company with the Commission have been delivered to
the Underwriters. After the execution of this Agreement, the Company will
file with the Commission either (i) if the registration statement, as it
may have been amended, has been declared

<PAGE>

by the Commission to be effective under the Act, a prospectus in the form
most recently included in that registration statement (or, if an amendment
thereto shall have been filed, in such amendment), with such changes or
insertions as are required by Rule 430A under the Act or permitted by Rule
424(b) under the Act and as have been provided to and approved by the
Underwriters prior to the execution of this Agreement, or (ii) if that
registration statement, as it may have been amended, has not been declared
by the Commission to be effective under the Act, an amendment to that
registration statement, including a form of prospectus, a copy of which
amendment has been furnished to and approved by the Underwriters prior to
the execution of this Agreement. The Company also may file a related
registration statement with the Commission pursuant to Rule 462(b) under
the Act for purposes of registering certain additional Securities, which
registration statement shall become effective upon filing with the
Commission (the "Rule 462(b) Registration Statement").  As used in this
Agreement, the term "Registration Statement" means that registration
statement, as amended at the time it was or is declared effective, and any
amendment thereto that was or is thereafter declared effective, including
all financial schedules and exhibits thereto and any information omitted
therefrom pursuant to Rule 430A under the Act and included in the
Prospectus (as hereinafter defined), together with any Rule 462(b)
Registration Statement; the term "Preliminary Prospectus" means each
prospectus subject to completion filed with the Registration Statement
(including the prospectus subject to completion, if any, included in the
Registration Statement at the time it was or is declared effective); and
the term "Prospectus" means the prospectus first filed with the Commission
pursuant to Rule 424(b) under the Act or, if no prospectus is so filed
pursuant to Rule 424(b), the prospectus included in the Registration
Statement. The Company has caused to be delivered to the Underwriters
copies of each Preliminary Prospectus and has consented to the use of those
copies for the purposes permitted by the Act.  If the Company has elected
to rely on Rule 462(b) and the Rule 462(b) Registration Statement has not
been declared effective, then (i) the Company has filed a Rule 462(b)
Registration Statement in compliance with and that is effective upon filing
pursuant to Rule 462(b) and has received confirmation of its receipt and
(ii) the Company has given irrevocable instructions for transmission of the
applicable filing fee in connection with the filing of the Rule 462(b)
Registration Statement, in compliance with Rule 111 promulgated under the
Act or the Commission has received payment of such filing fee.

          (b)  The Commission has not issued any order preventing or
suspending the use of any Preliminary Prospectus. When each Preliminary
Prospectus and each amendment and each supplement thereto was filed with
the Commission it (i) contained all statements required to be stated
therein, in accordance with, and complied with the requirements of, the Act
and the rules and regulations of the Commission thereunder and (ii) did not
include any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading. When
the Registration Statement was or is declared effective, it (i) contained
or will contain all statements required to be stated therein in accordance
with, and complied or will comply with the requirements of, the Act and the
rules and regulations of the Commission thereunder and (ii) did not or will
not include any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein not misleading. When
the Prospectus and each amendment or supplement thereto is filed with the
Commission pursuant to Rule 424(b) (or, if the Prospectus or such amendment
or supplement is not required so to be filed, when the Registration
Statement containing such Prospectus or amendment

                                    2

<PAGE>

or supplement thereto was or is declared effective) and on the Firm Closing
Date and any Option Closing Date (as each such term is hereinafter
defined), the Prospectus, as amended or supplemented at any such time, (i)
contained or will contain all statements required to be stated therein in
accordance with, and complied or will comply with the requirements of, the
Act and the rules and regulations of the Commission thereunder and (ii) did
not or will not include any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements therein,
in light of the circumstances under which they were made, not misleading.
The foregoing provisions of this paragraph (b) do not apply to statements
or omissions made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any amendment or supplement thereto in reliance upon
and in conformity with written information furnished to the Company by the
Underwriters specifically for use therein.

          (c)  The Company is duly incorporated, validly existing and in
good standing under the laws of its jurisdiction of incorporation, and is
duly qualified or authorized to transact business as a foreign corporation
and is in good standing in each jurisdiction where the ownership or leasing
of its properties or the conduct of its businesses require such
qualification or authorization. The Company has no subsidiaries.

          (d)  The Company has full corporate power and authority, and all
necessary material authorizations, approvals, orders, licenses,
certificates and permits of and from all governmental regulatory
authorities, to own or lease its property and conduct its business as now
being conducted and as proposed to be conducted as described in the
Registration Statement and the Prospectus (and, if the Prospectus is not in
existence, the most recent Preliminary Prospectus).

          (e)  The Company does not own, directly or indirectly, an
interest in any corporation, partnership, limited liability company, joint
venture, trust or other business entity.

          (f)  The Company has an authorized, issued and outstanding
capitalization as set forth in the Prospectus (and, if the Prospectus is
not in existence, the most recent Preliminary Prospectus). All of the
issued shares of capital stock of the Company, have been duly authorized
and validly issued and are fully paid, nonassessable and free of preemptive
rights. There are no outstanding options, warrants or other rights granted
by the Company to purchase shares of its Common Stock or other securities,
other than as described in the Prospectus (and, if the Prospectus is not in
existence, the most recent Preliminary Prospectus).  The Firm Shares have
been duly authorized, by all necessary corporate action on the part of the
Company and, when the Firm Shares are issued and delivered to and paid for
by the Underwriter pursuant to this Agreement, the Firm Shares will be
validly issued, fully paid, nonassessable and free of preemptive rights and
will conform to the description thereof in the Prospectus (and, if the
Prospectus is not in existence, the most recent Preliminary Prospectus).
No holder of outstanding securities of the Company is entitled as such to
any preemptive or other right to subscribe for any of the Securities, and
no person is entitled to have securities registered by the Company under
the Registration Statement or otherwise under the Act other than as
described in the Prospectus (and, if the Prospectus is not in existence,
the most recent Preliminary Prospectus).

existence, the most recent Preliminary Prospectus).

          (h)  All issuances of securities of the Company have been
effected pursuant to an exemption from the registration requirements of the
Act.  Except as previously disclosed in writing to the Representative, no

statements have been prepared in accordance with generally accepted
accounting principles in effect in the United States of America,
consistently applied, except to the extent that certain footnote
disclosures regarding unaudited interim periods may have been omitted in
accordance with the applicable rules of the Commission under the Securities
Exchange Act of 1934, as amended (the "1934 Act"). The financial data set
forth under the caption "Summary Financial Information" in the Prospectus
(and, if the Prospectus is not in existence, the most recent Preliminary
Prospectus) fairly present, on the basis stated in the Prospectus (or such
Preliminary Prospectus), the information included therein.

          (j)  Causey Demgen & Moore Inc., Certified Public Accountants,
which has audited certain financial statements of the Company and delivered
its report with respect to the financial statements included in the
Registration Statement and the Prospectus (and, if the Prospectus is not in

public accountant with respect to the Company as required by the Act and
the applicable rules and regulations thereunder.

          (k)  Since the respective dates as of which information is given

in the business, operations, condition (financial or otherwise), earnings
or prospects of the Company, whether or not arising in the ordinary course
of business, (ii) except as otherwise stated therein, there have been no
transactions entered into by the Company and no commitments made by the
Company that, individually or in the aggregate, are material with respect
to the Company, (iii) there has not been any change in the capital stock or
indebtedness of the Company, and (iv) there has been no dividend or
distribution of any kind declared, paid or made by the Company in respect

          (l)  The Company has full corporate power and authority to enter
into and perform its obligations under this Agreement and the
Representative's Warrant Agreement (as hereinafter defined). The execution
and delivery of this Agreement and the Representative's Warrant Agreement
have been duly authorized by all necessary corporate action on the part of
the Company and this Agreement and the Representative's Warrant Agreement
have each been duly executed and delivered

                                    4

by the Company and each is a valid and binding agreement of the Company,
enforceable against the Company in accordance with its terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency,
reorganization, fraudulent conveyance, moratorium and other similar laws
affecting creditors' rights generally and by general principles of equity
(regardless of whether enforcement is considered in a proceeding in equity
or at law), and except as rights to indemnity and contribution under this
Agreement may be limited by applicable law.  The issuance, offering and
sale by the Company to the Underwriters of the Securities pursuant to this
Agreement or the Representative's Securities pursuant to the
Representative's Warrant Agreement, the compliance by the Company with the
provisions of this Agreement and the Representative's Warrant Agreement,
and the consummation of the other transactions contemplated by this
Agreement and the Representative's Warrant Agreement do not (i) require the
consent, approval, authorization, registration or qualification of or with
any court or governmental or regulatory authority, except such as have been
obtained or may be required under state securities or blue sky laws and, if
the Registration Statement filed with respect to the Securities (as
amended) is not effective under the Act as of the time of execution hereof,
such as may be required (and shall be obtained as provided in this
Agreement) under the Act, or (ii) conflict with or result in a breach or
violation of, or constitute a default under, any material contract,
indenture, mortgage, deed of trust, loan agreement, note, lease or other
material agreement or instrument to which the Company is a party or by
which the Company or any of its property is bound or subject, or the
certificate of incorporation or by-laws of the Company, or any statute or

the Company is a party or to which the property of the Company is subject,
and no such proceedings have been threatened against the Company or with
respect to any of its property, except such as are described in the
Prospectus (and, if the Prospectus is not in existence, the most recent
Preliminary Prospectus). No contract or other document is required to be
described in the Registration Statement or the Prospectus or to be filed as
an exhibit to the Registration Statement that is not described therein
(and, if the Prospectus is not in existence, in the most recent Preliminary
Prospectus) or filed as required.

          (n)  The Company is not in (i) violation of its certificate of
incorporation, by-laws or other governing documents, (ii) violation in any
material respect of any law, statute, regulation, ordinance, rule, order,
judgment or decree of any court or any governmental or regulatory authority
applicable to it, or (iii) default in any material respect in the
performance or observance of any obligation, agreement, covenant or
condition contained in any material contract, indenture, mortgage, deed of
trust, loan agreement, note, lease or other material agreement or
instrument to which it is a party or by which it or any of its property may
be bound or subject, and no event has occurred which with notice or lapse
of time or both would constitute such a default.

          (o)  The Company currently owns or possesses adequate rights to
use all intellectual property, including all trademarks, service marks,
trade names, copyrights, inventions, know-how, trade secrets, proprietary
technologies, processes and substances, or applications or licenses
therefor, that are described in the Prospectus (and if the Prospectus is
not in existence, the most recent Preliminary Prospectus), and any other
rights or interests in items of intellectual property

                                    5

<PAGE>

as are necessary for the conduct of the business now conducted or proposed
to be conducted by them as described in the Prospectus (or, such
Preliminary Prospectus), and, except as disclosed in the Prospectus (and
such Preliminary Prospectus), the Company is not aware of the granting of
any patent rights to, or the filing of applications therefor by, others,
nor is the Company aware of, nor has the Company received notice of,
infringement of or conflict with asserted rights of others with respect to
any of the foregoing. All such intellectual property rights and interests
are (i) valid and enforceable and (ii) to the best knowledge of the
Company, not being infringed by any third parties.

          (p)  The Company possesses adequate licenses, orders,
authorizations, approvals, certificates or permits issued by the
appropriate federal, state or foreign regulatory agencies or bodies
necessary to conduct its business as described in the Registration
Statement and the Prospectus (and, if the Prospectus is not in existence,
the most recent Preliminary Prospectus), and, except as disclosed in the
Prospectus (and, if the Prospectus is not in existence, the most recent
Preliminary Prospectus), there are no pending or, to the best knowledge of
the Company, threatened, proceedings relating to the revocation or
modification of any such license, order, authorization, approval,
certificate or permit.

          (q)  The Company has good and marketable title to all of the
properties and assets reflected in the Company's financial statements or as
described in the Registration Statement and the Prospectus (and, if the
Prospectus is not in existence, the most recent Preliminary Prospectus),
subject to no lien, mortgage, pledge, charge or encumbrance of any kind,
except those reflected in such financial statements or as described in the
Registration Statement and the Prospectus (and such Preliminary
Prospectus). Except as disclosed in the Prospectus, the Company occupies
its leased properties under valid and enforceable leases conforming to the
description thereof set forth in the Registration Statement and the
Prospectus (and such Preliminary Prospectus).

          (r)  The Company is not and does not intend to conduct its
business in a manner in which it would be an "investment company" as
defined in Section 3(a) of the Investment Company Act of 1940 (the
"Investment Company Act").

          (s)  The Company has obtained and delivered to the Representative
the agreements (the "Lock-up Agreements") with the officers, directors and
certain other security holders owning shares of Common Stock substantially
to the effect that, among other things, each such person will not,
commencing on the date that the Registration Statement is declared
effective by the Commission (the "Effective Date") and continuing until
March 15, 2000, without the prior written consent of the Representative,
directly or indirectly, publicly sell, offer or contract to sell or grant
any option to purchase, transfer, assign or pledge, or otherwise encumber,
or dispose of any shares of Common Stock now or hereafter owned by such
person and that the purchaser or transferee in any private sale agrees to
be bound by the Lock-up Agreement.

          (t)  No labor dispute with the employees of the Company exists,
is threatened or, to the best of the Company's knowledge, is imminent that
could result in a material adverse change in the condition (financial or
otherwise), business, prospects, net worth or results of operations of the
Company, except as described in or contemplated by the Prospectus (and, if
the Prospectus is not in

                                    6

<PAGE>

existence, the most recent Preliminary Prospectus).

          (u)  The Company is insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are
prudent and customary in the businesses in which it is engaged; the Company
has not been refused any insurance coverage sought or applied for; and the
Company has no reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not materially and adversely affect the
condition (financial or otherwise), business, prospects, net worth or
results of operations of the Company, except as described in or
contemplated by the Prospectus (and, if the Prospectus is not in existence,
the most recent Preliminary Prospectus).

          (v)  The Representative's Warrant (as hereinafter defined) will
conform to the description thereof in the Registration Statement and in the
Prospectus (and, if the Prospectus is not in existence, the most recent
Preliminary Prospectus) and, when sold to and paid for by the
Representative in accordance with the Representative's Warrant Agreement,
will have been duly authorized and validly issued and will constitute valid
and binding obligations of the Company entitled to the benefits of the
Representative's Warrant Agreement. The shares of Common Stock issuable
upon exercise of the Representative's Warrant  (the "Representative's
Warrant Shares") have been duly authorized and reserved for issuance upon
exercise of the Representative's Warrant by all necessary corporate action
on the part of the Company and, when issued and delivered and paid for upon
such exercise in accordance with the terms of the Representative's Warrant
Agreement and the Representative's Warrant, respectively, will be validly
issued, fully paid, nonassessable and free of preemptive rights and will
conform to the description thereof in the Prospectus (and, if the
Prospectus is not in existence, the most recent Preliminary Prospectus).

          (w)  No person has acted as a finder in connection with, or is
entitled to any commission, fee or other compensation or payment for
services as a finder for or for originating, or introducing the parties to,
the transactions contemplated herein and the Company will indemnify the
Underwriter with respect to any claim for finder's fees in connection
herewith. Except as set forth in the Registration Statement and the
Prospectus (and, if the Prospectus is not in existence, the most recent
Preliminary Prospectus), the Company has no management or financial
consulting agreement with anyone except __________. No promoter, officer,
director or stockholder of the Company is, directly or indirectly,
affiliated or associated with an NASD member and no securities of the
Company have been acquired by an NASD member, except as previously
disclosed in writing to the Representative.

          (x)  The Company has filed all federal, state, local and foreign
tax returns which are required to be filed through the date hereof, or has
received extensions thereof, and has paid all taxes shown on such returns
and all assessments received by it to the extent that the same are material
and have become due.

          (y)  Neither the Company nor any director, officer, agent,
employee or other person associated with or acting on behalf of the Company
has, directly or indirectly; used any

                                    7

<PAGE>

corporate funds for unlawful contributions, gifts, entertainment, or other
unlawful expenses relating to political activity; made any unlawful payment
to foreign or domestic government officials or employees or to foreign or
domestic political parties or campaigns from corporate funds; violated any
provision of the Foreign Corrupt Practices Act of 1977, as amended; or made
any bribe, rebate, payoff, influence payment, kickback, or other unlawful
payment.  No transaction has occurred between or among the Company and any
of its officers or directors or any affiliates of any such officer or
director, that is required to be described in and is not described in the
Registration Statement and the Prospectus.

          (z)  Neither the Company nor any of its officers, directors or
affiliates (as defined in the Regulations), has taken or will take,
directly or indirectly, prior to the completion of the Offering, any action
designed to stabilize or manipulate the price of any security of the
Company, or which has caused or resulted in, or which might in the future
reasonably be expected to cause or result in, stabilization or manipulation
of the price of any security of the Company, to facilitate the sale or
resale of any of the Securities or the Option Securities.

     2.   PURCHASE, SALE AND DELIVERY OF THE SECURITIES AND THE
REPRESENTATIVE'S WARRANTS.

          (a)  On the basis of the representations, warranties, agreements
and covenants herein contained and subject to the terms and conditions
herein set forth, the Company agrees to issue and sell to each Underwriter,
and each Underwriter agrees, severally and not jointly, to purchase from
the Company, the number of Firm Shares as set forth opposite its name on
Schedule 1 annexed hereto, at the purchase price indicated in the
Prospectus.

          (b)  Certificates in definitive form for the Firm Securities that
the Underwriters have agreed to purchase hereunder, and in such
denomination or denominations and registered in such name or names as the
Underwriters request upon notice to the Company at least 48 hours prior to
the Firm Closing Date, shall be delivered by or on behalf of the Company to
the Underwriters, against payment by or on behalf of the Underwriters of
the purchase prices therefor by wire transfer of immediately available
funds to a bank account specified by the Company.  Such delivery of the
Firm Securities shall be made at the offices of Counsel for the
Underwriters, 5445 DTC Parkway, Suite 520, Englewood, Colorado 80111 at
7:30 A.M., Denver  time within five days from the Effective Date of the
Offering, or at such other place, time or date as the Underwriters and the
Company may agree upon, such time and date of delivery against payment
being herein referred to as the "Firm Closing Date."  The Company will make
such certificates for the Firm Securities available for checking and
packaging by the Underwriters, at such offices as may be designated by the
Representative, at least 24 hours prior to the Firm Closing Date.  In lieu
of physical delivery, the closing may occur by "DTC" delivery.

          (c)  For the purpose of covering any over-allotments in
connection with the distribution and sale of the Firm Securities as
contemplated by the Prospectus, the Company hereby grants to the
Underwriter an option to purchase any or all of the Option Shares, which
options are exercisable by the Representative on behalf of and for the
account of the Underwriters. The purchase price to be paid for any of the
Option Shares shall be the same price per share for the Firm Securities

                                    8

<PAGE>

set forth above in paragraph (a) of this Section 2. The option granted
hereby may be exercised as to all or any part of the Option Shares from
time to time within 45 calendar days after the Firm Closing Date. The
Underwriters shall not be under any obligation to purchase any of the
Option Shares prior to the exercise of such option. The Representative may
from time to time exercise the option granted hereby on behalf of the
Underwriters by giving notice in writing or by telephone (confirmed in
writing) to the Company setting forth the aggregate number of Option Shares
as to which the Underwriters are then exercising the option and the date
and time for delivery of and payment for such Option Shares. Any such date
of delivery shall be determined by the Underwriters but shall not be
earlier than two business days or later than three business days after such
exercise of the option and, in any event, shall not be earlier than the
Firm Closing Date. The time and date set forth in such notice, or such
other time on such other date as the Representative and the Company may
agree upon, is herein called the "Option Closing Date" with respect to such
Option Shares. Upon exercise of the option as provided herein, the Company
shall become obligated to sell to the Underwriters, and, subject to the
terms and conditions herein set forth, each Underwriter shall become
obligated to purchase from the Company, the  Option Shares as to which the
Underwriter is then exercising its option. If the option is exercised as to
all or any portion of the Option Shares, certificates in definitive form
for such Option Shares, and payment therefor, shall be delivered on the
related Option Closing Date in the manner, and upon the terms and
conditions, set forth in paragraph (b) of this Section 2, except that
reference therein to the Firm Securities and the Firm Closing Date shall be
deemed, for purposes of this paragraph (c), to refer to such Option Shares
and Option Closing Date, respectively.

          (d)  On the Firm Closing Date, the Company will further issue and
sell to the Representative or, at the direction of the Representative, to
bona fide officers of the Underwriters, for an aggregate purchase price of
$100, warrants to purchase Common Stock (the "Representative's Warrant")
entitling the holders thereof to purchase an aggregate of ______ shares of
Common Stock  for a period of four years, such period to commence on the
first anniversary of the Effective Date. The Representative's Warrant shall
be exercisable at the price indicated in the Prospectus, and shall contain
terms and provisions more fully described herein below and as set forth
more particularly in the warrant agreement relating to the Representative's
Warrant to be executed by the Company on the Effective Date (the
"Representative's Warrant Agreement"), including, but not limited to, (i)
customary anti-dilution provisions in the event of stock dividends, split
mergers, sales of all or substantially all of the Company's assets, sales
of stock below then prevailing market or exercise prices and other events,
and (ii) prohibitions of mergers, consolidations or other reorganizations
of or by the Company or the taking by the Company of other action during
the five-year period following the Effective Date unless adequate provision
is made to preserve, in substance, the rights and powers incidental to the
Representative's Warrant.  As provided in the Representative's Warrant
Agreement, the Representative may designate that the Representative's
Warrant be issued in varying amounts directly to bona fide officers of the
Underwriters. As further provided, no sale, transfer, assignment, pledge or
hypothecation of the Representative's Warrant shall be made for a period of
12 months from the Effective Date, except (i) by operation of law or
reorganization of the Company, or (ii) to the Underwriters and bona fide
partners, officers of the Underwriters and selling group members.

     3.   OFFERING BY THE UNDERWRITERS. The Underwriters propose to offer
the Firm Securities for sale to the public upon the terms set forth in the
Prospectus (the "Offering").

     4.   COVENANTS OF THE COMPANY. The Company covenants and agrees with
the Underwriters that:

          (a)  The Company will use its best efforts to cause the
Registration Statement, if not effective at the time of execution of this
Agreement, to become effective as promptly as possible.  If required, the
Company will file the Prospectus and any amendment or supplement thereto
with the Commission in the manner and within the time period required by
Rule 424(b) under the Act. During any time when a prospectus relating to
the Securities is required to be delivered under the Act, the Company (i)
will comply with all requirements imposed upon it by the Act and the rules
and regulations of the Commission thereunder to the extent necessary to
permit the continuance of sales of or dealings in the Securities in
accordance with the provisions hereof and of the Prospectus, as then
amended or supplemented, and (ii) will not file with the Commission any
prospectus or amendment referred to in the first sentence of section  (a)
(i) hereof, any amendment or supplement to such prospectus or any amendment
to the Registration Statement as to which the Underwriters shall not
previously have been advised and furnished with a copy for a reasonable
period of time prior to the proposed filing and as to which filing the
Underwriters shall not have given their consent. The Company will prepare
and file with the Commission, in accordance with the rules and regulations
of the Commission, promptly upon request by the Underwriters or counsel to
the Underwriters, any amendments to the Registration Statement or
amendments or supplements to the Prospectus that may be necessary or
advisable in connection with the distribution of the Securities by the
Underwriters, and will use its best efforts to cause any such amendment to
the Registration Statement to be declared effective by the Commission as
promptly as possible. The Company will advise the Underwriters, promptly
after receiving notice thereof, of the time when the Registration Statement
or any amendment thereto has been filed or declared effective or the
Prospectus or any amendment or supplement thereto has been filed and will
provide evidence satisfactory to the Underwriters of each such filing or
effectiveness.

          (b)  The Company will advise the Underwriters, promptly after
receiving notice or obtaining knowledge thereof, of (i) the issuance by the
Commission of any stop order suspending the effectiveness of the
Registration Statement or any order preventing or suspending the use of any
Preliminary Prospectus or the Prospectus or any amendment or supplement
thereto, (ii) the suspension of the qualification of any Securities for
offering or sale in any jurisdiction, (iii) the institution, threat or
contemplation of any proceeding for any such purpose, or (iv) any request
made by the Commission for amending the Registration Statement, for
amending or supplementing the Prospectus or for additional information. The
Company will use its best efforts to prevent the issuance of any such stop
order and, if any such stop order is issued, to obtain the withdrawal
thereof as promptly as possible.

          (c)  The Company will, in cooperation with counsel to the
Underwriters, arrange for the qualification of the Securities for offering
and sale under the blue sky or securities laws of such jurisdictions as the
Underwriters may designate and will continue such qualifications in effect
for as

                                   10

<PAGE>

long as may be necessary to complete the distribution of the Securities.

          (d)  If, at any time when a prospectus relating to the Securities
is required to be delivered under the Act, any event occurs as a result of
which the Prospectus, as then amended or supplemented, would include any
untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, or if for any
other reason it is necessary at any time to amend or supplement the
Prospectus to comply with the Act or the rules or regulations of the
Commission thereunder, the Company will promptly notify the Underwriters
thereof and, subject to Section 4(a) hereof, will prepare and file with the
Commission, at the Company's expense, an amendment to the Registration
Statement or an amendment or supplement to the Prospectus that corrects
such statement or omission or effects such compliance.

          (e)  Intentionally left blank.

          (f)  The Company will, without charge, provide to the
Underwriters and to counsel for the Underwriters (i) as many signed copies
of the Registration Statement originally filed with respect to the
Securities and each amendment thereto (in each case including exhibits
thereto) as the Underwriters may reasonably request, (ii) as many conformed
copies of such Registration Statement and each amendment thereto (in each
case without exhibits thereto) as the Underwriters may reasonably request,
and (iii) so long as a prospectus relating to the Securities is required to
be delivered under the Act, as many copies of each Preliminary Prospectus
or the Prospectus or any amendment or supplement thereto as the
Underwriters may reasonably request.

          (g)  The Company, as soon as practicable, will make generally
available to its security holders and to the Underwriters an earnings
statement of the Company that satisfies the provisions of Section 11 (a) of
the Act and Rule 158 thereunder.

          (h)  The Company will reserve and keep available for issuance
that maximum number of authorized but unissued shares of Common Stock which
are issuable upon exercise of any outstanding warrants and the
Representative's Warrant (including the underlying securities) outstanding
from time to time.

          (i)  The Company will apply the net proceeds from the sale of the
Securities being sold by it as set forth under "Use of Proceeds" in the
Prospectus.

          (j)  Intentionally left blank.

          (k)  Prior to the Closing Date or the Option Closing Date (if
any), the Company will not, directly or indirectly, without prior written
consent of the Representative, issue any press release or other public
announcement or hold any press conference with respect to the Company or
its activities with respect to the Offering (other than trade releases
issued in the ordinary course of the Company's business consistent with
past practices with respect to the Company's operations).

                                   11

          (l)  If, at the time that the Registration Statement becomes
effective, any information shall have been omitted therefrom in reliance
upon Rule 430A under the Act, then immediately following the execution of
this Agreement, the Company will prepare, and file or transmit for filing
with the Commission in accordance with Rule 430A and Rule 424(b) under the
Act, copies of the Prospectus including the information omitted in reliance
on Rule 430A, or, if required by such Rule 430A, a post-effective amendment
to the Registration Statement (including an amended Prospectus), containing
all information so omitted.

          (m)  The Company will cause the Securities to be included in The
Nasdaq SmallCap Market on the Effective Date and to maintain such listing
thereafter. The Company will file with The Nasdaq SmallCap Market all
documents and notices that are required by companies with securities that
are traded on The Nasdaq SmallCap Market.

          (n)  During the period of five years from the Firm Closing Date,
the Company will, as promptly as possible, not to exceed 135 days, after
each annual fiscal period render and distribute reports to its stockholders
which will include audited statements of its operations and changes of
financial position during such period and its audited balance sheet as of
the end of such period, as to which statements the Company's independent
certified public accountants shall have rendered an opinion and shall
timely file all reports  required to be filed under the securities laws.

          (o)  During a period of three years commencing with the Firm
Closing Date, the Company will furnish to the Representative, at the
Company's expense, copies of all periodic and special reports furnished to
stockholders of the Company and of all information, documents and reports
filed with the Commission.

          (p)  The Company has appointed Corporate Stock Transfer, Inc. as
transfer agent for the Common Stock, subject to the Closing. The Company
will not change or terminate such appointment for a period of three years
from the Firm Closing Date without first obtaining the written consent of
the Representative. For a period of three years after the Effective Date,
the Company shall cause the transfer agent to deliver promptly to the
Underwriters a duplicate copy of the daily transfer sheets relating to
trading of the Securities. The Company shall also provide to the
Representative, on a weekly basis, copies of the DTC special securities
positions listing report.

          (q)  During the period of 180 days after the date of this
Agreement, the Company will not at any time, directly or indirectly, take
any action designed to or that will constitute, or that might reasonably be
expected to cause or result in, the stabilization of the price of the
Common Stock to facilitate the sale or resale of any of the Securities.

          (r)  The Company will not take any action to facilitate the sale
of any shares of Common Stock pursuant to Rule 144 under the Act if any
such sale would violate any of the terms of the Lock-up Agreements.

          (s)  Prior to the 120th day after the Firm Closing Date, the
Company will provide the Underwriters and their designees with three bound
volumes of the transaction documents relating

the Company's securities. Copies of all documents that the Company or its
public relations firm intend to distribute will be provided to the
Representative for review prior to such distribution.

          (u)  The Company and the Underwriters will advise each other
immediately in writing as to any investigation, proceeding, order, event or
other circumstance, or any threat thereof, by or relating to the Commission
or any other governmental authority, that could impair or prevent the
Offering. Except as required by law or as otherwise mutually agreed in
writing, neither the Company nor the Underwriters will acquiesce in such
circumstances and each will actively defend any proceedings or orders in
that connection.

          (v)  The Company shall first submit to the Representative
certificates representing the Securities for approval prior to printing,
and shall, as promptly as possible, after filing the Registration Statement
with the Commission, obtain CUSIP numbers for the Securities.

          (w)  The Company will prepare and file a registration statement
with the Commission pursuant to section 12 of the 1934 Act, and will use
its best efforts to have such registration statement declared effective by
the Commission on the Effective Date. For this purpose the Company shall
prepare and file with the Commission a General Form of Registration of
Securities (Form 8-A).

          (x)  For so long as the Securities are registered under the 1934
Act, the Company will hold an annual meeting of stockholders for the
election of directors within 180 days after the end of each of the
Company's fiscal years and within 135 days after the end of each of the
Company's fiscal years will provide the Company's stockholders with the
audited financial statements of the Company as of the end of the fiscal
year just completed prior thereto. Such financial statements shall be those
required by Rule 14a-3 under the 1934 Act and shall be included in an
annual report pursuant to the requirements of such Rule.

          (y)  The Company will engage a financial public relations firm
reasonably satisfactory to the Representative on or before the Firm Closing
Date, and continuously engage such firm, or a substitute firm reasonably
acceptable to the Representative, for a period of twelve (12) months
following the Firm Closing Date.

          (z)  The Company will take all necessary and appropriate actions
to be included in Standard and Poor's Corporation Descriptions or other
equivalent manual and to maintain its listing therein for a period of five
(5) years from the Effective Date.  Such application shall be made on an
accelerated basis no more than two days following the Effective Date.

          (aa) On or prior to the Effective Date, the Company will give
written instructions to the transfer agent for the Common Stock directing
said transfer agent to place stop-order restrictions against, and
appropriate legends advising of the Lock-up Agreements on, the certificates
representing the securities of the Company owned by the persons who have
entered into the Lock-up Agreements.

          (bb) During the twelve-month period commencing on the later of
the Effective Date and the Closing Date, and provided that the
Representative agrees to a complete or partial release of the restrictions
contained in a Lock-up Agreement, the Company shall grant the
Representative the right to sell, within seven business days of the
effective date of such release, for the account of any person who was a
shareholder of the Company prior to the Offering and who owns at least five
percent (5%) of the Company's Common Stock after the Offering, any
securities sold pursuant to Rule 144 under the Act, provided that such sale
is made in accordance with the applicable shareholder's instructions.

          (cc) [???] During the twelve-month period commencing on the later
of the Effective Date or the Firm Closing Date, the Company and each of the
shareholders owning 5% or more of the Company's Common Stock immediately
preceding the Effective Date, shall grant the Representative the right of
first offer to act as lead manager, placement agent, or investment banker
with respect to any proposed underwritten public distribution or private
placement of the Company's securities having an aggregate value of
$5,000,000 or more, or any merger, acquisition or disposition of assets of
the Company and any fairness opinions or valuations.  Accordingly, if
during such period, the Company intends to make such a transaction, the
Company shall notify the Representative in writing of such intention and of
the proposed terms of the transaction.  The Representative shall notify the
Company within seven (7) days of the receipt of such notice of intention,
of the Representative's election to exercise its right to act as lead
manager, placement agent or investment banker, with respect to such
transaction.  If such right is not exercised by the Representative and the
terms of the applicable transaction are subsequently modified, the Company
shall resubmit such modified transaction to the Representative.  The
Representative's election not to exercise its rights in any particular
instance shall not affect in any way such right with respect to any
subsequent transaction by the Company.

          (dd) Prior to the Effective Date, the Company will have taken all
necessary and appropriate action to have at least two persons be elected to
the Company's Board of Directors who are deemed to be independent of the
Company's management.

and the descriptions of the consequences to the Company under such statutes
and regulations are fair summaries of the information set forth therein and
are accurate in all material respects; to the knowledge of such counsel,

court or governmental authority known to us, except such as have been
obtained and such as may be required under state blue sky or securities
laws as to which we express no opinion or (2) conflicts with or results in
a breach or violation of, or constitutes a default under, any material
contract, indenture, mortgage, deed of trust, loan agreement, note, lease
or other material agreement or instrument known to such counsel to which
the Company is a party or by which the Company or any of its property is
bound or subject, or the certificate of incorporation or by-laws of the
Company, or any material statute or any judgment, decree, order, rule or
regulation of any court or other governmental or regulatory authority known
to us applicable to the Company;

               (8)  to the knowledge of such counsel, (A) no legal or
governmental proceedings are pending to which the Company is a party or to
which the property of the Company is subject except those arising in the
ordinary course of business and fully covered by insurance and (B) no
contract or other document is required to be described in the Registration
Statement or the Prospectus or to be filed as an exhibit to the
Registration Statement that is not described therein or filed as required;

               (9)  to the knowledge of such counsel, the Company possesses
adequate licenses, orders, authorizations, approvals, certificates or
permits issued by the appropriate federal, state or local regulatory
agencies or bodies necessary to conduct its business as described in the
Registration Statement and the Prospectus, and, there are no pending or
threatened proceedings relating to the revocation or modification of any
such license, order, authorization, approval, certificate or permit, except
as disclosed in the Registration Statement and the Prospectus, which would
have a material adverse effect on the Company;

               (10) The Company is not in violation or breach of, or in
default with respect to, any term of its certificate of incorporation or
by-laws, and to the knowledge of such counsel, the Company is not in (i)

respect in the performance or observance of any obligation, agreement,
covenant or condition contained in any material contract, indenture,
mortgage, deed of trust, loan agreement, note, lease or other material
agreement or instrument to which it is a party or by which it or any of its
property may be bound or subject, and no event has occurred which with
notice, lapse of time or both would constitute such a default.

               (11) The Shares have been approved for inclusion on The
Nasdaq SmallCap Market;

               (12) The Registration Statement is effective under the Act;
any required filing of the Prospectus pursuant to Rule 424(b) has been made
in the manner and within the time period required by Rule 424(b); and to
our knowledge, no stop order suspending the effectiveness of the
Registration Statement or any amendment thereto has been issued, and no
proceedings for that purpose have been instituted or threatened or, to the
best knowledge of such counsel, are contemplated by the Commission;

                                   18

<PAGE>

               (13) The Registration Statement originally filed with
respect to the Securities and each amendment thereto and the Prospectus (in
each case, other than the financial statements, the notes, schedules and
other financial and statistical information contained therein, as to which
such counsel need express no opinion) comply as to form in all material
respects with the applicable requirements of the Act and the rules and
regulations of the Commission thereunder; and

               (14) the Company is not an "investment company" as defined
in Section 3(a) of the Investment Company Act of 1940 and, if the Company
conducts its business as set forth in the Prospectus, it will not become an
"investment company" and will not be required to register under the
Investment Company.

          Such counsel also shall state in its opinion that it has
participated in the preparation of the Registration Statement and the
Prospectus and that nothing has come to its attention that has caused it to
believe that the Registration Statement, at the time it became effective
(including the information deemed to be a part of the Registration
Statement at the time of effectiveness pursuant to Rule 430A(b), if
applicable), contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make
the statements therein not misleading or that the Prospectus, as of its
date or as of the Firm Closing Date, contained an untrue statement of
material fact or omitted to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which
they were made, not misleading.

     In rendering any such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deems proper, on certificates of
responsible officers of the Company and public officials, copies of which
certificates will be provided to the Underwriters, and, as to matters of
the laws of certain jurisdictions, on the opinions of other counsel to the
Company, which opinions shall also be delivered to the Underwriters, in
form and substance acceptable to the Underwriters, if such other counsel
expressly authorize such reliance and counsel to the Company expressly
states in their opinion that such counsel's and the Underwriters' reliance
upon such opinion is justified.

          (d)  A.   At the time this Agreement is executed, the
Representative shall have received a letter, dated such date, addressed to
the Underwriters in form and substance satisfactory (including the non-
material nature of the changes or decreases, if any, referred to in clause
(iii) below) in all respects to the Representative and Representative's
counsel, from Causey Demgen & Moore Inc., Certified Public Accountants:

               (i)  confirming that it is a independent certified public

the applicable Rules and Regulations;

               (ii) stating that it is their opinion that the financial
statements of the Company included in the Registration Statement comply as
to form in all material respects with the applicable accounting
requirements of the Act and the Rules and Regulations thereunder and that
the Representative may rely upon the opinion of the Certified Public

Registration Statement;

                                   19

<PAGE>

               (iii)     stating that, on the basis of a limited review
which included a reading of the latest available unaudited interim
financial statements of the Company, a reading of the latest available
minutes of the stockholders and board of directors and the various
committees of the boards of directors of the Company, consultations with
officers and other employees of the Company responsible for financial and
accounting matters and other specified procedures and inquiries (which, as
to the interim financial statements included in the Registration Statement,
shall constitute a review as described in SAS No. 71, Interim Financial
Statements), nothing has come to the Certified Public Accountants'
attention which would lead them to believe that (A) the unaudited financial
statements of the Company included in the Registration Statement do not
comply as to form in all material respects with the applicable accounting
requirements of the Act and the Rules and Regulations or are not fairly
presented in conformity with generally accepted accounting principles
applied on a basis substantially consistent with that of the audited
financial statements of the Company included in the Registration Statement,
or (B) at a specified date not more than five (5) days prior to the
Effective Date, there has been any change in the capital stock or long-term

Statement, other than as set forth in or contemplated by the Registration

31, 1998 to a specified date not more than five (5) days prior to the
Effective Date, there was any decrease (increase) in net revenues, net
income (loss) or in net earnings (loss) per common share of the Company, in
each case as compared with the corresponding period in December 31, 1998,
other than as set forth in or contemplated by the Registration Statement,
or, if there was any such decrease, setting forth the amount of such
decrease (increase);

               (iv) setting forth, at a date not later than five (5) days

numbers, percentages, statements and information may be derived from the
general accounting records, including work sheets, of the Company and
excluding any questions requiring an interpretation by legal counsel, with
the results obtained from the application of specified readings, inquiries
and other appropriate procedures (which procedures do not constitute an
examination in accordance with generally accepted auditing standards) set
forth in the letter and found them to be in agreement; and

               (vi) statements as to such other matters incident to the
transaction contemplated hereby as the Representative may request.

          B.   At the Firm Closing Date and the Option Closing Date, if
any, the Representative shall have received from the Certified Public
Accountants, a letter, dated as of the Firm Closing Date or the Option
Closing Date, as the case may be, to the effect that it reaffirms that

430A(b) and have found such amounts, percentages and financial information

each case as described in or contemplated by the Prospectus (exclusive of
any amendment or supplement thereto).

PROVIDED, HOWEVER, that the Company will not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or
is based upon any untrue statement or alleged untrue statement or omission
or alleged omission made in such Registration Statement or any amendment
thereto, any Preliminary Prospectus, the Prospectus or any amendment or
supplement thereto, or any Application in reliance upon and in conformity
with written information furnished to the Company by the Underwriters,
specifically for use therein.  This indemnity agreement will be in addition
to any liability which the Company may otherwise have. The Company will
not, without the prior written consent of the Underwriters, or controlling
person, settle

                                   22

<PAGE>

or compromise or consent to the entry of any judgment in any pending or
threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not the Underwriters or
any person who controls the Underwriters or within the meaning of Section
15 of the Act or Section 20 of the 1934 Act is a party to such claim,
action, suit or proceeding), unless such settlement, compromise or consent
includes an unconditional release of the Underwriters and each such
controlling person from all liability arising out of such claim, action,
suit or proceeding.

          (b)  The Underwriters will indemnify and hold harmless the
Company, each of its directors, each of its officers who signed the
Registration Statement, and each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20 of the 1934 Act
against, any losses, claims, damages or liabilities to which the Company or
any such director, officer, or controlling person may become subject under
the Act or otherwise, but only insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement or any amendment thereto, any
Preliminary Prospectus or the Prospectus or any amendment or supplement
thereto, or any Application, or (ii) the omission or the alleged omission
to state therein a material fact required to be stated in the Registration
Statement or any amendment thereto, any Preliminary Prospectus or the
Prospectus or any amendment or supplement thereto, or any Application, or
necessary to make the statements therein not misleading, in each case to
the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in reliance upon
and in conformity with written information furnished to the Company by the
Underwriters specifically for use therein; and, subject to the limitation
set forth immediately preceding this clause, will reimburse, as incurred,
any legal or other expenses reasonably incurred by the Company or any such
director, officer, or controlling person in connection with investigating
or defending against any such loss, claim, damage, liability, action
investigation, litigation or proceedings, in respect thereof. This
indemnity agreement will be in addition to any liability which the
Underwriters may otherwise have.

          (c)  Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified
party will, if a claim in respect thereof is to be made against the
indemnifying party under this Section 7, notify the indemnifying party of
the commencement thereof; but the omission so to notify the indemnifying
party will not relieve it from any liability which it may have to any
indemnified party otherwise than under this Section 7. In case any such
action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will
be entitled to participate therein and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, to assume the
defense thereof, with counsel satisfactory to such indemnified party;
PROVIDED, HOWEVER, that if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party
shall have reasonably concluded that there may be one or more legal
defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party,
the indemnifying party shall not have the right to direct the defense of
such action on behalf of such indemnified party or parties and such
indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or
parties. After notice from the indemnifying party to such indemnified party
of its election so to assume the

                                   23

<PAGE>

defense thereof and approval by such indemnified party of counsel appointed
to defend such action, the indemnifying party will not be liable to such
indemnified party under this Section 7 for any legal or other expenses,
other than reasonable costs of investigation, subsequently incurred by such
indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with
the proviso to the next preceding sentence or (ii) the indemnifying party
has authorized the employment of counsel for the indemnified party at the
expense of the indemnifying party. After such notice from the indemnifying
party to such indemnified party, the indemnifying party will not be liable
for the costs and expenses of any settlement of such action effected by
such indemnified party without the consent of the indemnifying party.

          (d)  In circumstances in which the indemnity obligation provided
for in the preceding paragraphs of this Section 7 is unavailable or
insufficient to hold harmless an indemnified party in respect of any
losses, claims, damages or liabilities (or actions in respect thereof),
each indemnifying party, in order to provide for just and equitable
contribution, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect (i) the relative benefits received by the
indemnifying party or parties on the one hand and the indemnified party on
the other from the offering of the Securities, or (ii) if the allocation
provided by the foregoing clause (i) is not permitted by applicable law,
not only such relative benefits but also the relative fault of the
indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions or alleged
statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof). The relative benefits received
by the Company on the one hand and the Underwriters on the other shall be
deemed to be in the same proportion as the total proceeds from the Offering
(net of underwriting discounts and commissions but before deducting
expenses) received by the Company bear to the total underwriting discounts
and commissions received by the Underwriters. The relative fault of the
parties shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission
or alleged omission to state a material fact relates to information
supplied by the Company or the Underwriters, the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission, and the other equitable considerations appropriate
in the circumstances. The Company and the Underwriters agree that it would
not be equitable if the amount of such contribution were determined by pro
rata or per capita allocation or by any other method of allocation that
does not take into account the equitable considerations referred to in the
first sentence of this paragraph (d). Notwithstanding any other provision
of this paragraph (d), the Underwriters shall not be obligated to make
contributions hereunder that in the aggregate exceeding the total public
offering price of the Securities purchased by the Underwriters under this
Agreement, less the aggregate amount of any damages that the Underwriters
have otherwise been required to pay in respect of the same or any
substantially similar claim, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11 (f) of the Act) shall
be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation. For purposes of this paragraph (d), each
person, if any, who controls an Underwriter within the meaning of Section
15 of the Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Underwriters, and each director of the Company, each
officer of the Company who signed the Registration Statement and each
person, if any, who controls the Company within the meaning of

                                   24

<PAGE>

Section 15 of the Act or Section 20 of the 1934 Act, shall have the same
rights to contribution as the Company.

     8.   SUBSTITUTION OF UNDERWRITERS.

     If any Underwriter shall for any reason not permitted hereunder cancel
its obligations to purchase the Firm Securities hereunder, or shall fail to
take up and pay for the number of Firm Securities set forth opposite names
in Schedule 1 hereto upon tender of such Firm Securities in accordance with
the terms hereof, then:

          (a)  If the aggregate number of Firm Securities which such
Underwriter or Underwriters agreed but failed to purchase does not exceed
10% of the total number of Firm Securities, the other Underwriters shall be
obligated to purchase the Firm Securities which such defaulting Underwriter
agreed but failed to purchase.

          (b)  If any Underwriter so defaults and the agreed number of Firm
Securities with respect to which such default or defaults occurs is more
than 10% of the total number of Firm Securities, the remaining Underwriters
shall have the right to take up and pay for the Firm Securities which the
defaulting Underwriter agreed but failed to purchase. If such remaining
Underwriters do not, at the Firm Closing Date, take up and pay for the Firm
Securities which the defaulting Underwriter agreed but failed to purchase,
the time for delivery of the Firm Securities shall be extended to the next
business day to allow the remaining Underwriters the privilege of
substituting within twenty-four hours (including nonbusiness hours) another
underwriter or underwriters satisfactory to the Company. If no such
underwriter or underwriters shall have been substituted as aforesaid,
within such twenty-four hour period, the time of delivery of the Firm
Securities may, at the option of the Company, be again extended to the next
following business day, if necessary, to allow the Company the privilege of
finding within twenty-four hours (including nonbusiness hours) another
underwriter or underwriters to purchase the Firm Securities which the
defaulting Underwriter or Underwriters agreed but failed to purchase. If it
shall be arranged for the remaining Underwriter or substituted Underwriters
to take up the Firm Securities of the defaulting Underwriter as provided in
this section, (i) the Company or the Underwriters shall have the right to
postpone the time of delivery for a period of not more than seven business
days, in order to effect whatever changes may thereby be made necessary in
the Registration Statement or the Prospectus, or in any other document or
arrangements, and the Company agrees promptly to file any amendments to the
Registration Statement or supplements to the Prospectus which may thereby
be made necessary, and (ii) the respective numbers of Firm Securities to be
purchased by the remaining Underwriters or substituted Underwriters shall
be taken as the basis of the underwriting obligation for all purposes of
this agreement.

     If in the event of a default by any Underwriter and the remaining
Underwriters shall not take up and pay for all the Firm Securities agreed
to be purchased by the defaulting Underwriter or substitute another
underwriter or underwriters as aforesaid, the Company shall not find or
shall not elect to seek another underwriter or underwriters for such Firm
Securities as aforesaid, then this Agreement shall terminate.

                                   25

<PAGE>

     If, following exercise of the option provided in Section 2(c) hereof,
any Underwriter or Underwriters shall for any reason not permitted
hereunder cancel their obligations to purchase Option Shares at the Option
Closing Date, or shall fail to take up and pay for the number of Option
Shares, which it became obligated to purchase at the Option Closing Date
upon tender of such Option Shares in accordance with the terms hereof, then
the remaining Underwriters or substituted Underwriters may take up and pay
for the Option Shares of the defaulting Underwriters in the manner provided
in Section 8(b) hereof. If the remaining Underwriters or substituted
Underwriters shall not take up and pay for all such Option Shares, the
Underwriters shall be entitled to purchase the number of Option Shares for
which there is no default or, at their election, the option shall
terminate, the exercise thereof shall be of no effect.

     As used in this Agreement, the term "Underwriter" includes any person
substituted for an Underwriter under this Section. In the event of
termination, there shall be no liability on the part of any non-defaulting
Underwriter to the Company, provided that the provisions of this Section 8
shall not in any event affect the liability of any defaulting Underwriter
to the Company arising out of such default.

     9.   SURVIVAL. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, any of its
officers or directors and the Underwriter set forth in this Agreement or
made by or on behalf of them, respectively, pursuant to this Agreement
shall remain in full force and effect, regardless of (i) any investigation
made by or on behalf of the Company, any of its officers or directors, the
Underwriter or any controlling person referred to in Section 7 hereof, and
(ii) delivery of and payment for the Securities. The respective agreements,
covenants, indemnities and other statements set forth in Sections 4 and 7
hereof shall remain in full force and effect, regardless of any termination
or cancellation of this Agreement.

     10.  TERMINATION.

          (a)  This Agreement may be terminated with respect to the Firm
Securities or any Option Shares in the sole discretion of the
Representative by notice to the Company given prior to the Firm Closing
Date or the related Option Closing Date, respectively, in the event that
the Company shall have failed, refused or been unable to perform all
obligations and satisfy all conditions on its part to be performed or
satisfied under Section 6 hereunder at or prior thereto or if at or prior
to the Firm Closing Date or such Option Closing Date, respectively:

               (1)  the Company sustains a loss by reason of explosion,
fire, flood, accident or other calamity, which, in the opinion of the
Underwriter, substantially affects the value of the properties of the
Company or which materially interferes with the operation of the business
of the Company regardless of whether such loss shall have been insured;
there shall have been any material adverse change, or any development
involving a prospective material adverse change (including, without
limitation, a change in management or control of the Company), in the
business, operations, condition (financial or otherwise), earnings or
prospects of the Company, except in each case as described in or
contemplated by the Prospectus (exclusive of any amendment or supplement
thereto);

                                   26

<PAGE>

               (2)  any action, suit or proceeding shall be threatened,
instituted or pending, at law or in equity, against the Company, by any
person or by any federal, state, foreign or other governmental or
regulatory commission, board or agency wherein any unfavorable result or
decision could materially adversely affect the business, operations,
condition (financial or otherwise), earnings or prospects of the Company;

               (3)  trading in the Common Stock shall have been suspended
by the Commission, the NASD or on Nasdaq, or trading in securities
generally on the New York Stock Exchange shall have been suspended or
minimum or maximum prices shall have been established on either such
exchange or quotation system;

               (4)  a banking moratorium shall have been declared by New
York or United States authorities;

               (5)  there shall have been (A) an outbreak of hostilities
between the United States and any foreign power (or, in the case of any
ongoing hostilities, a material escalation thereof), (B) an outbreak of any
other insurrection or armed conflict involving the United States or (C) any
other calamity or crisis or material change in financial, political or
economic conditions, having an effect on the financial markets that, in any
case referred to in this clause (5), in the sole judgment of the
Underwriter makes it impracticable or inadvisable to proceed with the
public offering or the delivery of the Securities as contemplated by the
Registration Statement; and

               (6)  termination of this Agreement pursuant to this Section
10 shall be without liability of any party to any other party, except as
provided in Section 5(b) and Section 7 hereof.

     11.  INFORMATION SUPPLIED BY THE UNDERWRITER.  The statements set
forth in the "Underwriting Section" in any Preliminary Prospectus or the
Prospectus constitute the only information furnished by the Underwriter to
the Company for the purposes of Section 7(b) hereof. The Underwriter
confirms that such statements (to such extent) are correct.

     12.  NOTICES.  All notice hereunder to or upon either party hereto
shall be deemed to have been duly given for all purposes if in writing and
(i) delivered in person or by messenger or an overnight courier service
against receipt, or (ii) send by certified or registered mail, postage

right hereunder shall constitute or operate as a waiver of any such right.
No waiver of any provision hereof shall be effective, unless in writing and
signed by or on behalf of the party to be charged therewith. No waiver
shall be deemed a continuing waiver or waiver in respect of any other or
subsequent breach or default, unless expressly so stated in writing.

prospective breach or default by either party hereto, the other party shall
be entitled to equitable relief, including remedies in the nature of

default, including the recovery of damages.

          REPRESENTATIVE'S WARRANT AGREEMENT dated as of ____________, 1999
by and between ENTROPIN, INC., (the "Company") and NEIDIGER TUCKER BRUNNER,
INC. ("Representative").

                          W I T N E S S E T H:
                           -------------------


     WHEREAS, the Company proposes to issue to the Representative _______
warrants (each a "Representative's Warrant") each to purchase one share of
the Company's $.001 par value common stock, (the "Common Stock").

     WHEREAS, the Representative has agreed, pursuant to the underwriting
agreement (the "Underwriting Agreement") dated _________, 1999 by and
between the Representative and the Company, to act as the Representative in
connection with the Company's proposed public offering (the "Public
Offering") of _________ shares of Common Stock (the "Offering Securities");
and

     WHEREAS, the Representative's Stock Warrants to be issued pursuant to
this Agreement will be issued on the Firm Closing Date (as such term is
defined in the Underwriting Agreement) by the Company to the Representative
in consideration for, and as part of, the Representative's compensation in
connection with the Representative's acting as the Representative pursuant
to the Underwriting Agreement;

     NOW, THEREFORE, in consideration of the premises, the payment by the
Representative to the Company of One Hundred Dollars ($100.00), the
agreements herein set forth and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties
hereto agree as follows:

     1.   GRANT.  The Holder (as defined in Section 3 below) is hereby
granted the right to purchase, at any time from ____________, 2000 until
5:00 p.m., New York time, __________, 2004, up to ________  shares of
Common Stock, at an initial purchase price (subject to adjustment as
provided in Section 8 hereof) of $______ per share of Common Stock subject
to the terms and conditions of this Agreement.  The securities issuable
upon exercise of the Representative's Warrant are sometimes referred to
herein as the "Representative's Securities."

<PAGE>

     2.   WARRANT CERTIFICATES.  The warrant certificate (the
"Representative's Warrant Certificate") to be delivered pursuant to this
Agreement shall be in the form set forth in Exhibit A attached hereto and
made a part hereof, with such appropriate insertions, omissions,
substitutions, and other variations as required or permitted by this Agreement.

     3.   EXERCISE OF REPRESENTATIVE'S WARRANT.

          (a)  The Representative's Warrant is exercisable during the term
set forth in Section 1 hereof payable by certified or cashier's check or
money order in lawful money of the United States.  Upon surrender of
Representative's Warrant Certificate with the annexed Form of Election to
Purchase duly executed, together with payment of the Purchase Price (as
hereinafter defined) for the Representative's Securities (and such other
amounts, if any, arising pursuant to Section 4 hereof) at the Company's
principal office, the registered holder of a Representative's Warrant
Certificate ("Holder" or "Holders") shall be entitled to receive a
certificate or certificates for the Representative's Securities so
purchased.  The purchase rights represented by each Representative's
Warrant Certificate are exercisable at the option of the Holder or Holders
thereof, in whole or in part as to Representative's Securities.  The
Representative's Warrant may be exercised to purchase all or any part of
the Representative's Securities represented thereby.  In the case of the
purchase of less than all the Representative's Securities purchasable on
the exercise of the Representative's Warrant represented by a
Representative's Warrant Certificate, the Company shall cancel the
Representative's Warrant Certificate represented thereby upon the surrender
thereof and shall execute and deliver a new Representative's Warrant
Certificate of like tenor for the balance of the Representative's
Securities purchasable thereunder.

          (b)  In lieu of the payment of cash upon exercise of the
Representative's Warrant as provided in Section 3(a), the Holder may
exercise the Representative's Warrant by surrendering the Representative's
Warrant Certificate at the principal office of the Company, accompanied by
a notice stating (i) the Holder's intent to effect such exercise by an
exchange, (ii) the Common Stock to be issued upon the exchange, (iii)
whether Representative's Warrants are to be surrendered in connection with
the exchange, and (iv) the date on which the Holder requests that such
exchange is to occur.  The Purchase Price for the Representative's
Securities to be acquired in the exchange shall be paid by the surrender as
indicated in the notice, of Representative's Warrants, having a "Value", as
defined below, equal to the Purchase Price.  "Value" as to each
Representative's Warrant shall mean the difference between the "Market
Price", as hereinafter defined, of a share of Common Stock and the then
Purchase Price for a share of Common Stock.

          By way of example of the application of the formula, assume that
the Market Price of the Common Stock is $8.00, the Purchase Price of the
Representative's Warrant is $6.00.  On such assumptions, the Value of a
Representative's Warrant is $2.00 ($8.00-$6.00) and therefore for each
three (3) Representative's Warrants surrendered, the Holder could acquire
one (1) share of Common Stock in the exchange.  Notwithstanding the
example, the Holder shall not be limited to exchanging Representative's
Warrants for Common Stock.

                                    2

<PAGE>

     The Warrant Exchange shall take place on the date specified in the
notice or if the date the notice is received by the Company is later than
the date specified in the notice, on the date the notice is received by the
Company.

     4.   ISSUANCE OF CERTIFICATES.  Upon the exercise of the
Representative's Warrant and payment of the Purchase Price therefor, the
issuance of certificates representing the Representative's Securities or
other securities, properties or rights underlying such Representative's
Warrant, shall be made forthwith (and in any event within five (5) business
days thereafter) without further charge to the Holder thereof, and such
certificates shall (subject to the provisions of Sections 5 and 7 hereof)
be issued in the name of, or in such names as may be directed by, the
Holder thereof; provided, however, that the Company shall not be required
to pay any tax which may be payable in respect of any transfer involved in
the issuance and delivery of any such certificates in a name other than
that of the Holder, and the Company shall not be required to issue or
deliver such certificates unless or until the person or persons requesting
the issuance thereof shall have paid to the Company the amount of such tax
or shall have established to the satisfaction of the Company that such tax
has been paid.  The Representative's Warrant Certificates and the
certificates representing the Representative's Securities or other
securities, property or rights (if such property or rights are represented
by certificates) shall be executed on behalf of the Company by the manual
or facsimile signature of the then present Chairman or Vice Chairman of the
Board of Directors or President or Vice President of the Company, attested
to by the manual or facsimile signature of the then present Secretary or
Assistant Secretary or Treasurer or Assistant Treasurer of the Company.
The Representative's Warrant Certificates shall be dated the date of
issuance thereof by the Company upon initial issuance, transfer or exchange.

     5.   RESTRICTION ON TRANSFER OF REPRESENTATIVE'S WARRANT. The Holder
of a Representative's Warrant Certificate (and its Permitted Transferee, as
defined below), by its acceptance thereof, covenants and agrees that until
____________, 2000 (one year following the effective date of the Public
Offering), the Representative's Warrant may not be sold, transferred,
assigned, hypothecated or otherwise disposed of, in whole or in part,
except to officers and partners of the Representatives, or any Public
Offering selling group member and their respective officers and partners,
("Permitted Transferees").  Thereafter the Representative's Warrant may be
transferred, assigned, hypothecated or otherwise disposed of in compliance
with applicable law.

     6.   PURCHASE PRICE.

          (a)  INITIAL AND ADJUSTED PURCHASE PRICE. Except as otherwise
provided in Section 8 hereof, the initial purchase price of the
Representative's Securities is set forth in Section 1.  The adjusted
purchase price shall be the price which shall result from time to time from
any and all adjustments of the initial purchase price in accordance with
the provisions of Section 8 hereof.

          (b)  PURCHASE PRICE. The term "Purchase Price" herein shall mean
the initial purchase price or the adjusted purchase price, depending upon
the context.

                                    3

     7.   REGISTRATION RIGHTS.

          (a)  REGISTRATION UNDER THE SECURITIES ACT OF 1933 AS AMENDED
("ACT"). The Representative's Warrant may have not been registered under
the Act.  The Representative's Warrant Certificates may bear the following
legend:

          "The securities represented by this certificate have not been
registered under the Securities Act of 1933 (the "Act"), and may not be
offered for sale or sold except pursuant to (i) an effective registration
statement under the Act, or (ii) an opinion of counsel, if such opinion and
counsel shall be reasonably satisfactory to counsel to the issuer, that an
exemption from registration under the Act is available."

          (b)  DEMAND REGISTRATION.   (1) At any time commencing on the
first anniversary of and expiring on the fifth anniversary of the effective
date of the Company's Registration Statement relating to the Public
Offering (the "Effective Date"), the Holders of a Majority (as hereinafter
defined) in interest of the Representative's Warrant, or the Majority in
interest of the Representative's Securities (assuming the exercise of all
of the Representative's Warrant) shall have the right, exercisable by
written notice to the Company, to have the Company prepare and file with
the U.S. Securities and Exchange Commission (the "Commission"), on one (1)
occasion, a registration statement on Form S-1 or  SB-2 or other
appropriate form, and such other documents, including a prospectus, as may
be necessary in the opinion of both counsel for the Company and counsel for
the Holders, in order to comply with the provisions of the Act, so as to
permit a public offering and sale, of the Representative's Securities by
such Holders and any other Holders of the Representative's Warrant and/or
the Representative's Securities who notify the Company within fifteen (15)
business days after receipt of the notice described in Section 7(b)(2).

               (2)  The Company covenants and agrees to give written notice
of any registration request under this Section 7(b) by any Holders to all
other registered Holders of the Representative's Warrant and the
Representative's Securities within ten (10) calendar days from the date of
the receipt of any such registration request.

               (3)  For purposes of this Agreement, the term "Majority" in
reference to the Holders of the Representative's Warrant or
Representative's Securities, shall mean in excess of fifty percent (50%) of
the then outstanding Representative's Warrant or Representative's
Securities that (i) are not held by the Company, an affiliate, officer,
creditor, employee or agent thereof or any of their respective affiliates,
members of their family, persons acting as nominees or in conjunction
therewith, or (ii) have not been resold to the public pursuant to a
registration statement filed with the Commission under the Act.

               (4)  The Company shall have no obligation to prepare and
file a registration statement pursuant to this Section 7(b) if, within
twenty (20) days after the Company  receives such a demand for
registration, the Company agrees, or insiders who own individually more
than 5% of the Company's outstanding Common Stock agree, to purchase the
Holder's Warrants and/or Warrant Shares from the requesting Holders at a
price equal to the difference between the Exercise Price then

                                    4

<PAGE>

in effect and the then current market price of the Company's Common Stock.
The market price of the Company's Common Stock shall be the average of the
closing asked prices for the Company's Common Stock during the ten (10)
business days period preceding such request.

          (c)  PIGGYBACK REGISTRATION.  (1) If, at any time within the
period commencing on the first anniversary and expiring on the sixth
anniversary of the Effective Date, the Company should file a registration
statement with the Commission under the Act (other than in connection with
a merger or other business combination transaction or pursuant to Form
S-8), it will give written notice at least twenty (20) calendar days prior
to the filing of each such registration statement to the Representative and
to all other Holders of the Representative's Warrant and/or the
Representative's Securities of its intention to do so.  If a Representative
or other Holders of the Representative's Warrant and/or the
Representative's Securities notify the Company within fifteen (15) calendar
days after receipt of any such notice of its or their desire to include any
Representative's Securities in such proposed registration statement, the
Company shall afford the Representative and such Holders of the
Representative's Warrant and/or Representative's Securities the opportunity
to have any such Representative's Securities registered under such
registration statement.  Notwithstanding the provisions of this Section
7(c)(1) and the provisions of Section 7(d), the Company shall have the
right at any time after it shall have given written notice pursuant to this
Section 7(c)(1) (irrespective of whether a written request for inclusion of
any such securities shall have been made) to elect not to file any such
proposed registration statement, or to withdraw the same after the filing
but prior to the effective date thereof.

               (2)  If the managing underwriter of an offering to which the
above piggyback rights apply, in good faith and for valid business reasons,
objects to such rights, such objection shall preclude such inclusion.

          (d)  COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.  In
connection with any registrations under Sections 7(b) and 7(c) hereof, the
Company covenants and agrees as follows:

               (1)  The Company shall use its best efforts to file a
registration statement within thirty (30) calendar days of receipt of any
demand therefor pursuant to Section 7(b); provided, however, that the
Company shall not be required to produce audited or unaudited financial
statements for any period prior to the date such financial statements are
required to be filed in a report on Form 10-K or Form 10-Q (or Form 10-KSB
or Form 10-QSB), as the case may be.  The Company shall use its best
efforts to have any registration statement declared effective at the
earliest possible time, and shall furnish each Holder desiring to sell
Representative's Securities such number of prospectuses as shall reasonably
be requested.

               (2)  The Company shall maintain the effectiveness of the
registration statement for a period of time equal to the lesser of 9 months
or until such time as all of the Warrant Shares have been sold pursuant to
the registration statement.

               (3)  The Company shall pay all costs (excluding fees and
expenses of Holders' counsel and any underwriting discounts or selling
fees, expenses or commissions), fees and

                                    5

<PAGE>

expenses in connection with any registration statement filed pursuant to
Sections 7(b) and 7(c) hereof including, without limitation, the Company's
legal and accounting fees, printing expenses, blue sky fees and expenses.

               (4)  The Company will use its best efforts to qualify or
register the Representative's Securities included in a registration
statement for offering and sale under the securities or blue sky laws of
such states as reasonably are requested by the Holders, provided that the
Company shall not be obligated to execute or file any general consent to
service of process or to qualify as a foreign corporation to do business
under the laws of any such jurisdiction.

               (5)  The Company shall indemnify the Holders of the
Representative's Securities to be sold pursuant to any registration
statement and each person, if any, who controls such Holders within the
meaning of Section 15 of the Act or Section 20(a) of the Securities
Exchange Act of 1934 (the "Exchange Act"), against all loss, claim, damage,
expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to
which any of them may become subject under the Act, the Exchange Act or
otherwise, arising from such registration statement, but only to the same
extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify the Representative contained in Section 8
of the Underwriting Agreement.

               (6)  The Holders of the Representative's Securities to be
sold pursuant to a registration statement, and their successors and
assigns, shall indemnify the Company, its officers and directors and each
person, if any, who controls the Company within the meaning of Section 15
of the Act or Section 20(a) of the Exchange Act, against all loss, claim,
damage or expense or liability to which they may become subject under the
Act, the Exchange Act or otherwise, arising from information furnished by
or on behalf of such Holders, or their successors or assigns, for specific
inclusion in such registration statement to the same extent and with the
same effect as the provisions contained in Section 8 of the Underwriting
Agreement pursuant to which the Representative has agreed to indemnify the
Company.

               (7)  Nothing contained in this Agreement shall be construed
as requiring the Holders to exercise their Representative's Warrant prior
to the initial filing of any registration statement or the effectiveness
thereof, provided that such Holders have made arrangements reasonably
satisfactory to the Company to pay the exercise price from the proceeds of
such offering.

               (8)  The Company shall furnish to each Representative for
the offering, if any, such documents as such Representative may reasonably
require.

               (9)  The Company shall as soon as practicable after the
effective date of the registration statement, and in any event within 15
months thereafter, make "generally available to its security holders"
(within the meaning of Rule 158 under the Act) an earnings statement (which
need not be audited) complying with Section 11(a) of the Act and covering
a period of at least 12 consecutive months beginning after the effective
date of the registration statement.

                                    6

<PAGE>

               (10) The Company shall deliver promptly to each Holder
participating in the offering requesting the correspondence described below
and any managing Representative copies of all correspondence between the
Commission and the Company, its counsel or auditors with respect to the
registration statement and permit each Holder and Representative to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems
reasonably necessary to comply with applicable securities laws or rules of
the National Association of Securities Dealers, Inc. ("NASD"). Such
investigation shall include access to books, records and properties and
opportunities to discuss the business of the Company with its officers and
independent auditors, all to such reasonable extent and at such reasonable
times and as often as any such Holder shall reasonably request.

               (11) The Company shall enter into an underwriting agreement
with the managing underwriter selected for such underwriting by Holders
holding a Majority of the Representative's Securities requested to be
included in such underwriting, provided, however that such managing
underwriter shall be reasonably acceptable to the Company, except that in
connection with an offering for which the Holders have piggyback rights,
the Company shall have the sole right to select the managing underwriter or
underwriters.  Such underwriting agreement shall be satisfactory in form
and substance to the Company, a Majority of such Holders (in respect of a
registration under Section 7(b) only) and such managing underwriter, and
shall contain such representations, warranties and covenants by the Company
and such other terms as are customarily contained in agreements of that
type.  The Holders shall be parties to any underwriting agreement relating
to an underwritten sale of their Representative's Securities.  Such Holders
shall not be required to make any representations or warranties to or
agreements with the Company or the underwriters except as they may relate
to such Holders and their intended methods of distribution.

     8.   ADJUSTMENTS TO PURCHASE PRICE AND NUMBER OF SECURITIES.

          (a)  COMPUTATION OF ADJUSTED PURCHASE PRICE.  Except as
hereinafter provided, in case the Company shall at any time after the date
hereof issue or sell any shares of Common Stock (other than the issuances
referred to in Section 8(g) hereof), including shares held in the Company's
treasury, for a consideration per share less than the "Market Price" (as
defined in Section 8(a)(6) hereof) per share of Common Stock on the date
immediately prior to the issuance or sale of such shares, or without
consideration, then forthwith upon any such issuance or sale, the Purchase
Price of the Common Stock shall (until another such issuance or sale) be
reduced to the price (calculated to the nearest full cent) determined by
dividing (1) the product of (a) the Purchase Price in effect immediately
before such issuance or sale and (b) the sum of (i) the total number of
shares of Common Stock outstanding immediately prior to such issuance or
sale, and (ii) the number of shares determined by dividing (A) the
aggregate consideration, if any, received by the Company upon such sale or
issuance, by (B) the Market Price, and by (2) the total number of shares of
Common Stock outstanding immediately after such issuance or sale provided,
however, that in no event shall the Purchase Price be adjusted pursuant to
this computation to an amount in excess of the Purchase Price in effect
immediately prior to such computation, except in the case of a combination
of outstanding shares of Common Stock, as provided by Section 8(c) hereof.

                                    7

<PAGE>

          For the purposes of this Section 8, the term "Purchase Price"
shall mean the Purchase Price of the Common Stock forming a part of the
Representative's Securities set forth in Section 6 hereof, as adjusted from
time to time pursuant to the provisions of this Section 8.

          For the purposes of any computation to be made in accordance with
this Section 8(a), the following provisions shall be applicable:

               (1)  In case of the issuance or sale of shares of Common
Stock (or of other securities deemed hereunder to involve the issuance or
sale of shares of Common Stock) for a consideration part or all of which
shall be cash, the amount of the cash consideration therefor shall be
deemed to be the amount of cash received by the Company for such shares
(or, if shares of Common Stock are offered by the Company for subscription,
the subscription price, or, if such securities shall be sold to
Representatives or dealers for public offering without a subscription
offering, the initial public offering price) before deducting therefrom any
compensation paid or discount allowed in the sale, underwriting or purchase
thereof by Representatives or dealers or others performing similar
services, or any expenses incurred in connection therewith.

               (2)  In case of the issuance or sale (otherwise than as a
dividend or other distribution on any stock of the Company, and otherwise
than on the exercise of options, rights or warrants or the conversion or
exchange of convertible or exchangeable securities) of shares of Common
Stock (or of other securities deemed hereunder to involve the issuance or
sale of shares of Common Stock) for a consideration part or all of which
shall be other than cash, the amount of the consideration therefor other
than cash shall be deemed to be the value of such consideration as
determined in good faith by the Board of Directors of the Company.

               (3)  Shares of Common Stock issuable by way of dividend or
other distribution on any stock of the Company shall be deemed to have been
issued immediately after the opening of business on the day following the
record date for the determination of stockholders entitled to receive such
dividend or other distribution and shall be deemed to have been issued
without consideration.

               (4)  The reclassification of securities of the Company other
than shares of Common Stock into securities including shares of Common
Stock shall be deemed to involve the issuance of such shares of Common
Stock for a consideration other than cash immediately prior to the close of
business on the date fixed for the determination of security holders
entitled to receive such shares, and the value of the consideration
allocable to such shares of Common Stock shall be determined as provided in
Section 8(a)(2).

               (5)  The number of shares of Common Stock at any one time
outstanding shall include the aggregate number of shares of Common Stock
issued or issuable (subject to readjustment upon the actual issuance
thereof) upon the exercise of options, rights or warrants and upon the
conversion or exchange of convertible or exchangeable securities.

                                    8

<PAGE>

               (6)  As used herein in the phrase "Market Price" at any date
shall be deemed to be the last reported sale price, or, in the case no such
reported sale takes place on such day, the average of the last reported
sales prices for the last three (3) trading days, in either case as
officially reported by the principal securities exchange on which the
Common Stock is listed or admitted to trading, or, if the Common Stock is
not listed or admitted to trading on any national securities exchange, the
average closing bid price as furnished by the NASD through the NASD
Automated Quotation System ("NASDAQ") or similar organization if NASDAQ is
no longer reporting such information, or if the Common Stock is not quoted
on NASDAQ, as determined in good faith by resolution of the Board of
Directors of the Company, based on the best information available to it.

          (b)  OPTIONS, RIGHTS, WARRANT AND CONVERTIBLE AND EXCHANGEABLE
SECURITIES. Except in the case of the Company issuing rights to subscribe
for shares of Common Stock distributed to all the stockholders of the
Company and Holders of Representative's Warrant pursuant to Section 8(i)
hereof, if the Company shall at any time after the date hereof issue
options, rights or warrants to purchase shares of Common Stock, or issue
any securities convertible into or exchangeable for shares of Common Stock
(other than the issuances referred to in Section 8(g) hereof), (i) for a
consideration per share less than the Market Price (including the issuance
thereof without consideration such as by way of dividend or other
distribution), or (ii) without consideration, the Purchase Price in effect
immediately prior to the issuance of such options, rights or warrants, or
such convertible or exchangeable securities, as the case may be, shall be
reduced to a price determined by making a computation in accordance with
the provisions of Section 8(a) hereof, provided that:

               (1)  The aggregate maximum number of shares of Common Stock
issuable or that may become issuable under such options, rights or warrants
(assuming exercise in full even if not then currently exercisable or
currently exercisable in full) shall be deemed to be issued and outstanding
at the time such options, rights or warrants were issued, and for a
consideration equal to the minimum purchase price per share provided for in
such options, rights or warrants at the time of issuance, plus the
consideration (determined in the same manner as consideration received on
the issue or sale of shares in accordance with the terms of the
Representative's Warrant), if any, received by the Company for such
options, rights or warrants; provided, however, that upon the expiration or
other termination of such options, rights or warrants, if any thereof shall
not have been exercised, the number of shares of Common Stock deemed to be
issued and outstanding pursuant to this Section 8(b)(1) (and for the
purposes of Section 8(a)(5) hereof) shall be reduced by such number of
shares as to which options, warrants and/or rights shall have expired or
terminated unexercised, and such number of shares shall no longer be deemed
to be issued and outstanding, and the Purchase Price then in effect shall
forthwith be readjusted and thereafter be the price which it would have
been had adjustment been made on the basis of the issuance only of shares
actually issued or issuable upon the exercise of those options, rights or
warrants as to which the exercise rights shall not be expired or terminated
unexercised.

               (2)  The aggregate maximum number of shares of Common Stock
issuable upon conversion or exchange of any convertible or exchangeable
securities (assuming conversion or exchange in full even if not then
currently convertible or exchangeable in full) shall be deemed to be issued
and outstanding at the time of issuance of such securities, and for a
consideration equal to the

                                    9

<PAGE>

consideration (determined in the same manner as consideration received on
the issue or sale of shares of Common Stock in accordance with the terms of
the Representative's Warrant) received by the Company for such securities,
plus the minimum consideration, if any, receivable by the Company upon the
conversion or exchange thereof; provided, however, that upon the expiration
or other termination of the right to convert or exchange such convertible
or exchangeable securities (whether by reason or redemption or otherwise),
the number of shares deemed to be issued and outstanding pursuant to this
Section 8(b)(2) (and for the purpose of Section 8(a)(5) hereof) shall be
reduced by such number of shares as to which the conversion or exchange
rights shall have expired or terminated unexercised, and such number of
shares shall no longer be deemed to be issued and outstanding and the
Purchase Price then in effect shall forthwith be readjusted and thereafter
be the price which it would have been had adjustment been made on the basis
of the issuance only of the shares actually issued or issuable upon the
conversion or exchange of those convertible or exchangeable securities as
to which the conversion or exchange rights shall not have expired or
terminated unexercised.

               (3)  If any change shall occur in the price per share
provided for in any of the options, rights or warrants referred to in
Section 8(b)(1), or in the price per share at which the securities referred
to in Section 8(b)(2) are convertible or exchangeable, and if a change in
the Purchase Price has not occurred by reason of the event giving rise to
the change in the price per share of such other options, rights, warrants,
or convertible or exchangeable securities, such options, rights or warrants
or conversion or exchange rights, as the case may be, to the extent not
theretofore exercised,  the  shall be deemed to have expired or terminated
on the date when such price change became effective in respect of shares
not theretofore issued pursuant to the exercise or conversion or exchange
thereof, and the Company shall be deemed to have issued upon such date new
options, rights or warrants or convertible or exchangeable securities at
the new price in respect of the number of shares issuable upon the exercise
of such options, rights or warrants or the conversion or exchange of such
convertible or exchangeable securities.

          (c)  SUBDIVISION AND COMBINATION. In case the Company shall at
any time issue any shares of Common Stock in connection with a stock
dividend in shares of Common Stock or subdivide or combine the outstanding
shares of Common Stock, the Purchase Price shall forthwith be
proportionately decreased in the case of a stock dividend or a subdivision
or increased in the case of combination.

          (d)  ADJUSTMENT IN NUMBER OF SECURITIES. Upon each adjustment of
the Purchase Price pursuant to the provisions of this Section 8, the number
of Representative's Securities issuable upon the exercise of the
Representative's Warrant shall be adjusted to the nearest whole share by
multiplying a number equal to the Purchase Price in effect immediately
prior to such adjustment by the number of Representative's Securities
issuable upon exercise of the Representative's Warrant immediately prior to
such adjustment and dividing the product so obtained by the adjusted
Purchase Price.

          (e)  DEFINITION OF COMMON STOCK. For the purpose of this
Agreement, the term "Common Stock" shall mean the class of stock designated
as Common Stock in the Certificate of Incorporation, of the Company as it
may be amended as of the date hereof.

                                   10

<PAGE>

          (f)  RECLASSIFICATION, MERGER OR CONSOLIDATION.  The Company will
not merge, reorganize or take any other action which would terminate the
Representative's Warrant without first making adequate provision for the
Representative's Warrant.  In case of any reclassification or change of the
outstanding shares of Common Stock issuable upon exercise of the
outstanding warrants (other than a change in par value to no par value, or
from nor par value to par value, or as a result of a subdivision or
combination), or in case of any consolidation of the Company with, or
merger of the Company with, or merger of the Company into, another
corporation (other than a consolidation or merger in which the Company is
the continuing corporation and which does not result in any
reclassification or change of the outstanding Common Stock except a change
as a result of a subdivision or combination of such shares or a change in
par value, as aforesaid), or in the case of a sale or conveyance to another
corporation or other entity of the property of the Company as an entirety
or substantially as an entirety, the Holders of each Representative's
Warrant then outstanding or to be outstanding shall have the right
thereafter (until the expiration of such Representative's Warrant) to
purchase, upon exercise of such Representative's Warrant, the kind and
number of shares of stock and other securities and property receivable upon
such reclassification, change, consolidation, merger, sale or conveyance as
if the Holders were the owner of the shares of Common Stock underlying the
Representative's Warrant immediately prior to any such events at a price
equal to the product of (x) the number of shares issuable upon exercise of
the Representative's Warrant and (y) the Purchase Price in effect
immediately prior to the record date for such reclassification, change,
consolidation, merger, sale or conveyance, as if such Holders had exercised
the Representative's Warrant.  In the event of a consolidation, merger,
sale or conveyance of property, the corporation formed by such
consolidation or merger, or acquiring such property, shall execute and
deliver to the Holders a supplemental Representative's warrant agreement to
such effect.  Such supplemental Representative's warrant agreement shall
provide for adjustments which shall be identical to the adjustment provided
for in this Section 8.  The provisions of this Section 8(f) shall similarly
apply to successive consolidations or mergers.

          (g)  NO ADJUSTMENT OF PURCHASE PRICE IN CERTAIN CASES.  No
adjustment of the Purchase Price shall be made:

               (1)  Upon the issuance or sale of (i) the Representative's
Warrant or the securities underlying the Representative's Warrant, (ii) the
securities sold pursuant to the Public Offering (including those sold upon
exercise of the Representative's over-allotment option), or (iii) the
shares issuable pursuant to the options, warrants, rights, stock purchase
agreements or convertible or exchangeable securities outstanding or in
effect on the date hereof as described in the prospectus relating to the
Public Offering.

               (2)  If the amount of said adjustments shall aggregate less
than two ($.02) cents for one (1) share of Common Stock; provided, however,
that in such case any adjustment that would otherwise be required then to
be made shall be carried forward and shall be made at the time of and
together with the next subsequent adjustment which, together with any
adjustment so carried forward, shall aggregate at least two ($.02) cents
for one (1) share of Common Stock.  In addition, Registered Holders shall
not be entitled to cash dividends paid by the Company prior to the exercise
of any warrant or warrants held by them.

                                   11

     9.   EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.  Each
Representative's Warrant Certificate is exchangeable without expense, upon
the surrender thereof by the registered Holders at the principal executive
office of the Company, for a new Representative's Warrant Certificate of
like tenor and date representing in the aggregate the right to purchase the
same number of Representative's Securities in such denominations as shall
be designated by the Holders thereof at the time of such surrender.

     10.  LOSS, THEFT, ETC. OF CERTIFICATES  Upon receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft, destruction or
mutilation of any Representative's Warrant Certificate, and, in case of
loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable
expenses incidental thereto, and upon surrender and cancellation of the
Representative's Warrant Certificates, if mutilated, the Company will make
and deliver a new Representative's Warrant Certificate of like tenor, in
lieu thereof.

     11.  ELIMINATION OF FRACTIONAL INTERESTS. The Company shall not be
required to issue certificates representing fractions of shares of Common
Stock upon the exercise of the Representative's Warrant, nor shall it be
required to issue scrip or pay cash in lieu of fractional interests;
provided, however, that if a Holder exercises all Representative's Warrant
held of record by such Holder the fractional interests shall be eliminated
by rounding any fraction to the nearest whole number of shares of Common
Stock or other securities, properties or rights.

     12.  RESERVATION AND LISTING OF SECURITIES. The Company shall at all
times reserve and keep available out of its authorized shares of Common
Stock, solely for the purpose of issuance upon the exercise of the
Representative's Warrant, such number of shares of Common Stock or other
securities and properties or rights as shall be issuable upon the exercise
thereof.  The Company covenants and agrees that, upon exercise of
Representative's Warrant and payment of the Purchase Price therefor, all
the shares of Common Stock issuable upon such exercise shall be duly and
validly issued, fully paid, non-assessable and not subject to the
preemptive rights of any stockholder.  As long as the Representative's
Warrant shall be outstanding, the Company shall use its best efforts to
cause the Common Stock to be listed (subject to official notice of
issuance) on all securities exchanges on which the Common Stock issued to
the public in connection herewith may then be listed or quoted.

     13.  NOTICES TO REPRESENTATIVE'S WARRANT HOLDERS. Nothing contained in
this Agreement shall be construed as conferring upon the Holders the right
to vote or to consent or to receive notice as a stockholder in respect of
any meetings of stockholders for the election of directors or any other
matter, or as having any rights whatsoever as a stockholder of the Company.
If, however, at any time prior to the expiration of the Representative's
Warrant and their exercise, any of the following events shall occur:

          (a)  the Company shall take a record of the holders of its shares
of Common Stock for the purpose of entitling them to receive a dividend or
distribution payable otherwise than in cash, or a cash dividend or
distribution payable otherwise than out of current or retained earnings, as
indicated by the accounting treatment of such dividend or distribution on
the books of the Company; or

                                   12

<PAGE>

          (b)  the Company shall offer to all the holders of its Common
Stock any additional shares of capital stock of the Company or securities
convertible into or exchangeable for shares of capital stock of the
Company, or any option, right or warrant to subscribe therefor; or

          (c)  a dissolution, liquidation or winding up of the Company
(other than in connection with a consolidation or merger) or a sale of all
or substantially all of its property, assets and business as an entirety
shall be proposed; then, in any one or more of said events, the Company
shall give written notice of such event at least fifteen (15) calendar days
prior to the date fixed as a record date or the date of closing the
transfer books for the determination of the stockholders entitled to such
dividend, distribution, convertible or exchangeable securities or
subscription rights, or entitled to vote on such proposed dissolution,
liquidation, winding up or sale. Such notice shall specify such record date
or the date of closing the transfer books, as the case may be.  Failure to
give such notice or any defect therein shall not affect the validity of any
action taken in connection with the declaration or payment of any such
dividend, or the issuance of any convertible or exchangeable securities, or
subscription rights, options or warrants, or any proposed dissolution,
liquidation, winding up or sale.

     14.  NOTICES.  All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed to have
been duly made when delivered, or five days after being mailed by
registered or certified mail, return receipt requested:

          (a)  If to the registered Holders of the Representative's
Warrant, to the address of such Holders as shown on the books of the
Company; or

          (b)  If to the Company to the address shown in the Underwriting
Agreement or to such other address as the Company may designate by notice
to the Holders.

     15.  SUPPLEMENTS AND AMENDMENTS.  The Company and the Representative
may from time to time supplement or amend this Agreement without the
approval of any Holders of Representative's Warrant Certificates (other
than the Representative) in order to cure any ambiguity, to correct or
supplement any provision contained herein which may be defective or
inconsistent with any provisions herein, or to make any other provision in
regard to matters or questions arising hereunder which the Company and the
Representative may deem necessary or desirable and which the Company and
the Representative deem shall not adversely affect the interests of the
Holders of Representative's Warrant Certificates.

     16.  SUCCESSORS.  All the covenants and provisions of this Agreement
shall be binding upon and inure to the benefit of the Company, the
Representative, the Holders and their respective successors and assigns
hereunder.

     17.  TERMINATION.  This Agreement shall terminate at the close of
business on _____________, 2005.  Notwithstanding the foregoing, the
indemnification provisions of Section 7 shall survive such termination
until the close of business on the expiration of any applicable statue of
limitations.

                                   13

<PAGE>

     18.  GOVERNING LAW; SUBMISSION TO JURISDICTION. This Agreement and
each Representative's Warrant Certificate issued hereunder shall be deemed
to be a contract made under the laws of the State of Colorado and for all
purposes shall be construed in accordance with the laws of said state
without giving effect to the rules of said state governing the conflicts of
laws.

     19.  ENTIRE AGREEMENT; MODIFICATION.  This Agreement (including the
Underwriting Agreement, to the extent portions thereof are referred to
herein) contains the entire understanding between the parties hereto with
respect to the subject matter hereof and thereof.  This Agreement may not
be modified or amended except by a writing duly signed by the Company and
the Holders of a Majority in Interest of the Representative's Securities
(for this purpose, treating all then outstanding Representative's Warrants
as if they had been exercised).

     20.  SEVERABILITY.  If any provision of this Agreement shall be held
to be invalid or unenforceable, such invalidity or unenforceability shall
not affect any other provision of this Agreement.

     21.  CAPTIONS.  The caption headings of the Sections of this Agreement
are for convenience of reference only and are not intended, nor should they
be construed as, a part of this Agreement and shall be given no substantive
effect.

     22.  BENEFITS OF THIS AGREEMENT.  Nothing in this Agreement shall be
construed to give to any person or corporation other than the Company and
the Representative and any other registered Holders of the Representative's
Warrant Certificates or Representative's Securities any legal or equitable
right, remedy or claim under this Agreement; and this Agreement shall be
for the sole and exclusive benefit of the Company and the Representative
and any other Holders of the Representative's Warrant Certificates or
Representative's Securities.

     23.  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts and each of such counterparts shall for all purposes be deemed
to be an original, and such counterparts shall together constitute but one
and the same instrument.

     24.  BINDING EFFECT.  This Agreement shall be binding upon and inure
to the benefit of the Company, the Representative and their respective
successors and assigns and the Holders from time to time of the
Representative's Warrant Certificates or any of them.

                           WARRANT CERTIFICATE

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933 (THE "ACT"), AND MAY NOT BE OFFERED FOR
SALE OR SOLD EXCEPT PURSUANT TO (i) AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE ACT, OR (ii) AN OPINION OF COUNSEL, IF SUCH OPINION AND COUNSEL
SHALL BE REASONABLY SATISFACTORY TO COUNSEL TO THE ISSUER, THAT AN
EXEMPTION FROM REGISTRATION UNDER THE ACT IS AVAILABLE.

THE TRANSFER OR EXCHANGE OF THE WARRANTS REPRESENTED BY THIS CERTIFICATE IS
RESTRICTED IN ACCORDANCE WITH THE WARRANT AGREEMENT REFERRED TO HEREIN.

             EXERCISABLE COMMENCING _________, 2000 THROUGH
              5:00 P.M., NEW YORK TIME ON ___________, 2005


                                        Warrant covering 110,000 shares of
                                        Common Stock
No. UW-1

          This Warrant Certificate certifies that Neidiger Tucker Brunner,
Inc. or registered assigns, is the registered holder of this Warrant to
purchase initially, at any time from ___________, 2000, until 5:00 p.m.,
New York time on __________, 2005 (the "Expiration Date"), up to 110,000
shares of Common Stock, $[___] par value (the "Common Stock") of Entropin,
Inc. ("Company") exercisable to purchase one share of Common Stock at a
purchase price of $_____ per share (the "Purchase Price"), upon the
surrender of this Warrant Certificate and payment of the applicable
Purchase Price at an office or agency of the Company, but subject to the
conditions set forth herein and in the Representative's Warrant Agreement,
dated as of _______, 1999, by and between the Company and Neidiger Tucker
Brunner, Inc. (the "Warrant Agreement").  Payment of the Purchase Price
shall be made by certified or cashier's check or money order payable to the
order of the Company.

          No Warrant may be exercised after 5:00 p.m., New York time, on
the Expiration Date, at which time all Warrant evidenced hereby, unless
exercised prior thereto, shall thereafter be void.

          The Warrant evidenced by this Warrant Certificate is part of a
duly authorized issue of Warrants issued pursuant to the Warrant Agreement
between the Company and the Representative, which Warrant Agreement is
hereby incorporated by reference in and made a part of this instrument

                                   17

<PAGE>

and is hereby referred to for a description of the rights, limitation of
rights, obligations, duties and immunities thereunder of the Company and
the holders (the words "holders" or "holder" meaning the registered holders
or registered holder) of the Warrant.

          The Warrant Agreement provides that upon the occurrence of
certain events the Purchase Price and the type and/or number of the
Company's securities issuable upon the exercise of this Warrant, may,
subject to certain conditions, be adjusted.  In such event, the Company
will, at the request of the holder, issue a new Warrant Certificate
evidencing the adjustment in the Purchase Price and the number and/or type
of securities issuable upon the exercise of the Warrant; provided, however,
that the failure of the Company to issue such new Warrant Certificates
shall not in any way change, alter, or otherwise impair, the rights of the
holder as set forth in the Warrant Agreement.

          Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrant shall be issued to the transferee(s) in
exchange as provided herein, without any charge except for any tax or other
governmental charge imposed in connection with such transfer.

          Upon the exercise of less than all of the Warrants evidenced by
this Certificate, the Company shall forthwith issue to the holder hereof a
new Warrant Certificate representing such number of unexercised Warrants.

          The Company may deem and treat the registered holder(s) hereof as
the absolute owner(s) of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone), for the
purpose of any exercise hereof, and of any distribution to the holder(s)
hereof, and for all other purposes, and the Company shall not be affected
by any notice to the contrary.

          All terms used in this Warrant Certificate which are defined in
the Warrant Agreement shall have the meanings assigned to them in the
Warrant Agreement.

          IN WITNESS WHEREOF, the undersigned has executed this certificate
this ____day of ________________, 1999.
