                                   THE COMPANY

         The  Company   identifies  and  evaluates   promising   pharmaceutical,
biomedical  and  medical   technologies   and   selectively   invests  in  those
technologies  which the Company believes possess strong market potential.  Under
sponsored research agreements with independent companies, universities and other
institutions    ("Sponsored   Research    Agreements"),    the   Company   funds
pharmaceutical, biomedical and medical research and clinical testing in exchange
for license rights to commercialize  resulting  products and  technologies.  The
Company's  strategy  is to  bridge  the  resource  and  management  gap  between
late-stage  research  and   commercialization  of  any  resulting  products  and
technologies by assisting in the management of research, development, marketing,
commercialization  and patent  prosecution  of  technologies  and  products.  In
addition,   the  Company   manages  the  preparation  and  submission  of  IND's
(Investigational  New Drug  Applications) and NDA's (New Drug  Applications) and
protocols prepared for submission to the U.S. Food and Drug  Administration (the
"FDA").  If Company funded  research and clinical  testing are  successful,  the
Company intends to enter into sublicense,  joint venture or other  collaborative
agreements with one or more  pharmaceutical,  biomedical or medical companies to
pursue later phase clinical testing and product manufacturing and marketing.  By
utilizing  third  party  development  and  distribution  resources,  the Company
believes that it can effectively avoid the substantial fixed costs traditionally
associated with in-house research, development, production and distribution.

         The  Company  does not intend to  manufacture  or market its  products.
Instead,  the Company intends to finance research  projects in consideration for
license rights. Thereafter, the Company will attempt to enter into manufacturing
and  marketing   agreements   with  one  or  more   established   biomedical  or
pharmaceutical companies for any products which are developed.

         As of the date of this  Prospectus,  the Company has  acquired  certain
development and marketing rights in the following technologies:

         RBC-CD4  ELECTROINSERTION  TECHNOLOGY.  The  Company  is the  worldwide
licensee  of certain  technology  (the  "RBC-CD4  Electroinsertion  Technology")
relating to the  electroinsertion  of full-length CD4 protein into the red blood
cell membrane ("RBC-CD4") for use as a therapeutic in the treatment of the human
immunodeficiency virus ("HIV") that leads to Acquired Immune Deficiency Syndrome
("AIDS").  The electroinsertion  process inserts CD4, the protein that serves as
the binding  site of the HIV virus,  into red blood  cells.  This  altered  cell
complex  acts as a decoy and is designed to cleanse  the blood of  infection  by
binding  to and  removing  the HIV virus from  circulation  before it can infect
other cells in the human immune  system.  The related Phase I/IIA clinical trial
was conducted by The Johns Hopkins University Medical Center.

         LIPOSOME-CD4  TECHNOLOGY.  The  Company is the  worldwide  licensee  of
certain technology (the "Liposome-CD4 Technology") relating to the incorporation
of CD4 antigens into liposome  bilayers and their use as a therapeutic  agent in
the  treatment of HIV and AIDS.  While  RBC-CD4  Electroinsertion  Technology is
being  developed  by the  Company  to target HIV and  HIV-infected  cells in the
blood,  Liposome-CD4  Technology is being  developed by the Company's  exclusive
sublicensee, SEQUUS Pharmaceuticals, to target infections in the human lymphatic
system, a major reservoir for infection not reached by blood circulation.

         HIV/AIDS VACCINE. The Company holds an exclusive worldwide license to a
potential  HIV/AIDS  vaccine and diagnostic  developed by Professor  Jean-Claude
Chermann,  one of the original Pasteur Institute discoverers of HIV. The vaccine
concept  developed by  Professor  Chermann  utilizes a cellular  antigen that is
incorporated  into the HIV viral coating after the HIV virus has reproduced in a
human cell.  This  cellular  antigen  does not appear to vary across the various
strains of the virus and may provide a stable target to develop  antibodies that
can prevent infection. The Company believes this approach may also protect

                                       -6-

<PAGE>

against both blood-born and sexual transmission of HIV. The Company's goal is to
develop an oral formulation that would make the vaccine  potentially less costly
and easier to distribute to a broad  population.  The related  research is being
conducted  by  Professor   Chermann  and  a  team  of  scientific   and  medical
investigators  affiliated  with the  French  National  Institute  of Health  and
Medical Research.

         UGIF TECHNOLOGY.  The Company holds an exclusive worldwide license to a
potential  prostate  cancer  therapy.   The  related  technology  focuses  on  a
urogenital sinus derived growth inhibitory factor that may inhibit the growth of
transformed  cells and tumors in the human  prostate.  The  related  research is
being conducted by scientific and medical  investigators  affiliated with Baylor
College of Medicine and headed by Dr. David R. Rowley.

         MEMBRANE ATTACK COMPLEX (MAC)/COMPLEMENT  TECHNOLOGY. The Company holds
exclusive   worldwide   license  rights  to  certain   membrane  attack  complex
(MAC)/complement   technology   relating  to  the  loading  of  therapeutic  and
diagnostic molecules into cells. Through the use of certain complement proteins,
pores or channels  can be formed in various cell  membranes,  allowing a pathway
for the entry of molecules  of various  sizes into such cells.  This  technology
could provide for the selective  delivery of various  therapeutic and diagnostic
agents to target,  I.E., cancer cells or viruses.  The related research is being
conducted  by  scientific  and medical  investigators  affiliated  with  Harvard
Medical School and headed by Dr. Jose Halpern.

         ION  PHARMACEUTICALS,  INC.  TECHNOLOGIES.  The  Company,  through  Ion
Pharmaceuticals,  a Delaware  corporation  and a wholly-owned  subsidiary of the
Company ("Ion"),  holds exclusive  worldwide license rights to certain compounds
and their uses for the treatment of conditions characterized by unregulated cell
proliferation  or cell growth and sickle  cell  anemia,  and holds an  exclusive
option  to  license  certain  compounds  and  their  uses for the  treatment  of
gastrointestinal  disorders,  such as  secretory  diarrhea.  Ion's  intellectual
property  portfolio consists of clotrimazole,  its metabolites,  and a number of
proprietary new chemical entities  co-owned by Ion termed the Trifens(TM).  Such
compounds have demonstrated  promise in therapeutic  applications for treating a
number of conditions  characterized by unregulated cell  proliferation,  such as
cancer  (including  multiple drug resistant  cancer) and certain  dermatological
conditions, as well as sickle cell anemia and secretory diarrhea.

         MULTI-DOSE INHALER (MSI). The Company holds exclusive worldwide license
rights to a  multi-dose  inhaler  of  Siemens  AG (the "MSI  Inhaler").  The MSI
Inhaler is a drug delivery system that allows for the  administration of a range
of drugs to the lungs for  asthma,  chronic  obstructive  pulmonary  disease and
other respiratory diseases.  In addition,  the MSI Inhaler's delivery system may
find  application  in the  treatment of  non-respiratory  illnesses  that may be
treated by drug  deliveries  to the lungs.  The  Company  plans to develop  drug
formulations for use with the MSI Inhaler.

         The  Company  was  organized  under  Canadian  law in  October  1986 as
Sheffield Strategic Metals, Inc. The Company commenced  operations in the United
States in January  1992  through its  wholly-owned  subsidiary,  U-Tech  Medical
Corporation,  a Texas  corporation  ("U-Tech"),  with its  principal  offices in
Houston,  Texas.  Effective May 19, 1992,  Sheffield  Medical  Technologies Inc.
became domesticated as a Washington  corporation in the State of Wyoming without
reincorporation  pursuant to a "continuance" procedure under Wyoming corporation
law.  On June 13,  1995,  the  Company  changed  its state of  incorporation  to
Delaware by means of a merger with and into a newly-formed wholly-owned Delaware
subsidiary of the Company. Such merger and the resulting change of the Company's
state of incorporation to Delaware was approved by the Company's stockholders in
January  1995.  Unless the context  otherwise  indicates,  the "Company" as used
herein means  Sheffield  Medical  Technologies  Inc., its  predecessors  and its
wholly-owned subsidiaries, U-Tech and Ion and CP Pharmaceuticals, Inc.

                                  RISK FACTORS

         THE SECURITIES  OFFERED HEREBY ARE HIGHLY  SPECULATIVE  AND PROSPECTIVE
PURCHASERS SHOULD BE AWARE THAT THE PURCHASE OF SUCH SECURITIES  INVOLVES A HIGH
DEGREE  OF RISK.  IN  ADDITION  TO OTHER  INFORMATION  IN THIS  PROSPECTUS,  THE
FOLLOWING  FACTORS  SHOULD BE  CONSIDERED  CAREFULLY IN  EVALUATING  THE COMPANY
BEFORE  PURCHASING THE  SECURITIES  OFFERED  HEREBY.  THIS  PROSPECTUS  CONTAINS
FORWARD- LOOKING STATEMENTS WHICH INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S
ACTUAL  RESULTS  COULD  DIFFER   MATERIALLY  FROM  THOSE  ANTICIPATED  IN  THESE
FORWARD-LOOKING  STATEMENTS AS A RESULT OF CERTAIN FACTORS,  INCLUDING THOSE SET
FORTH IN THE FOLLOWING RISK FACTORS AND ELSEWHERE IN THIS PROSPECTUS.

DEVELOPMENT STAGE COMPANY; HISTORY OF OPERATING LOSSES AND ACCUMULATED DEFICIT;
GOING CONCERN OPINION

         The Company is in the  development  stage.  The Company  commenced  its
biotechnology  operations  in the United  States in  January  1992  through  its
wholly-owned  subsidiary,  U-Tech, a Texas corporation,  to acquire, develop and
commercialize what it believed to be promising medical technologies.  On January
10, 1996,  Ion was formed as a wholly-owned  subsidiary of the Company.  At that
time,  Ion acquired the  Company's  rights to the  Company's  anti-proliferative
technology. The Company has been principally engaged to date in research funding
and licensing efforts, has experienced  significant  operating losses and, as of
March 31, 1997,  had an  accumulated  deficit of  $29,256,740.  The  independent
auditors' report dated February 12, 1997, except for Note 9 as to which the date
is March 14, 1997, on the Company's  consolidated  financial  statements  stated
that the Company has  generated  only minimal  operating  revenue,  has incurred
recurring  operating  losses  and  requires  additional  capital  and that these
conditions  raise  substantial  doubt  about its  ability to continue as a going
concern.  The  Company  expects  that it will  continue  to have a high level of
operating   expenses  and  will  be  required  to  make   significant   up-front
expenditures in connection with Sponsored  Research  Agreements with independent
companies,  universities and other institutions for research and development and
product development activities. As a result, the Company anticipates significant
additional  operating  losses  for 1997  and  that  such  losses  will  continue
thereafter  until  such  time,  if  ever,  as the  Company  is able to  generate
sufficient revenues to sustain its operations.

         The Company's ability to achieve profitable  operations is dependent in
large part on regulatory  approvals of its products and  technologies and on its
ability  to  enter  into  manufacturing  and  marketing  agreements  with  other
pharmaceutical,  biomedical or medical companies. There can be no assurance that
the Company will ever achieve profitable operations.

SIGNIFICANT LIQUIDITY RESTRAINTS

         The Company's cash available for funding its operations as of March 31,
1997 was $3,027,503. As of such date, the Company had trade payables and accrued
liabilities  of  $332,565,   current   Sponsored   Research   Agreement  funding
obligations of $1,172,310 and other  liabilities  of $43,375.  In addition,  the
Company  is  obligated  to  fund  between  such  date  and  September  30,  1997
approximately  $850,000  in the  aggregate  under  existing  Sponsored  Research
Agreements.  The Company  will be required  to obtain  additional  funds for its
business  through  operations  or  equity  or  debt  financings,   collaborative
arrangements with corporate partners or from other sources.  No assurance can be
given  that these  funds  will be  available  for the  Company  to  finance  its
development on acceptable  terms, if at all. If adequate funds are not available
from operations or additional  sources of funding,  the Company's  business will
suffer a material adverse effect.


                                       -8-

<PAGE>
NEED FOR ADDITIONAL FINANCING

         Since the Company does not expect to generate substantial revenues from
the sale of any products or  technologies in the immediate  future,  the Company
will require  substantial  additional  funds from other  sources to complete its
research and development,  to conduct additional clinical tests and to establish
manufacturing and marketing  relationships  with  pharmaceutical,  biomedical or
medical companies.  The Company will attempt to acquire funds for these purposes
through  operations,   additional  equity  or  debt  financings,   collaborative
arrangements with corporate partners or from other sources.  No assurance can be
given  that these  funds  will be  available  for the  Company  to  finance  its
development on acceptable  terms, if at all. If adequate funds are not available
from operations or additional  sources of funding,  the Company's  business will
suffer a material adverse effect.

LONG TERM DEVELOPMENT OF TECHNOLOGIES; NO COMMERCIALIZATION OF PRODUCTS TO DATE

         The  Company has not yet begun to  generate  revenues  from the sale of
products or  technologies.  The Company is funding  research that began, in some
cases,  many years  before the Company  acquired  rights in such  projects.  The
Company's  products  and  technologies  will  require   significant   additional
development,   laboratory  and  clinical   testing  and   investment   prior  to
commercialization.   The  Company  does  not  expect  regulatory   approval  for
commercial sales of any of its products or technologies in the immediate future.
There  can  be  no  assurance  that  such  products  or  technologies   will  be
successfully  developed,  prove to be safe and  efficacious in clinical  trials,
meet applicable regulatory standards,  obtain required regulatory approvals,  be
capable of being  produced in commercial  quantities  at reasonable  costs or be
successfully commercialized and marketed.

ROYALTY PAYMENT OBLIGATIONS

         The owners and  licensors  of the  technology  rights  acquired  by the
Company are entitled to receive up to 50% of all  royalties and payments in lieu
of royalties received by the Company from commercialization, if any, of products
in respect of which the Company holds licenses.  Accordingly, in addition to its
substantial investment in research and development of technologies,  the Company
will be  required to make  substantial  payments  to others in  connection  with
revenues derived from commercialization of products, if any, in respect of which
the Company holds licenses.  Consequently, the Company will not receive the full
amount of any revenues  that may be derived from  commercialization  of products
derived from the Company's technologies to fund ongoing operations.

POTENTIAL LOSS OF RIGHTS UPON DEFAULT

         Under  the terms of  Sponsored  Research  Agreements,  the  Company  is
obligated to make  periodic  installments  to finance  research and  development
activities  according  to  specified  budgets.  In the  event  that the  Company
defaults  in the  payment  of an  installment  under  the  terms of a  Sponsored
Research Agreement,  its rights thereunder could be forfeited. As a consequence,
the Company  could lose all rights under a Sponsored  Research  Agreement to the
related licensed  technology,  notwithstanding the total investment made through
the date of the default.  There can be no assurance that unforeseen  obligations
or  contingencies  will not  deplete  the  Company's  financial  resources  and,
accordingly,  the  Company's  resources  may not be  available  to  fulfill  the
Company's commitments.


DEPENDENCE ON PRINCIPAL INVESTIGATORS

         The Company is dependent upon the active participation of its principal
investigators in the advancement of the research and development associated with
their related projects.  The loss of a principal  investigator,  particularly in
the early  stages of the  development  of a  technology,  could  have a material
adverse effect on the related project and the Company's prospects.

                                       -9-

<PAGE>
RAPID TECHNOLOGICAL CHANGE; COMPETITION

         The medical research field is subject to rapid technological change and
innovation.  Pharmaceutical and biomedical  research and product development are
rapidly  evolving  fields in which  developments  are  expected to continue at a
rapid pace.  Reports of progress and potential  breakthroughs are occurring with
increasing  frequency.  There can be no  assurance  that the Company will have a
competitive  advantage in its fields of technology or in any of the other fields
in which the Company may concentrate its efforts.

         The  Company's  success  will  depend  upon its  ability to develop and
maintain   a   competitive   position   in   the   research,   development   and
commercialization   of  products  and   technologies  in  its  areas  of  focus.
Competition from  pharmaceutical,  chemical,  biomedical and medical  companies,
universities,  research  and other  institutions  is intense  and is expected to
increase.  All, or substantially  all, of these  competitors have  substantially
greater research and development  capabilities,  experience,  and manufacturing,
marketing,   financial  and  managerial  resources.   Further,  acquisitions  of
competing  companies by large  pharmaceutical  or other  companies could enhance
such competitors' financial,  marketing and other capabilities.  There can be no
assurance that developments by others will not render the Company's  products or
technologies  obsolete or not  commercially  viable or that the Company  will be
able to keep pace with technological developments.

GOVERNMENT REGULATION

         The Company's ongoing research and development  projects are subject to
rigorous  FDA  approval   procedures.   The  preclinical  and  clinical  testing
requirements to demonstrate safety and efficacy in each clinical indication (the
specific condition intended to be treated) and regulatory  approval processes of
the FDA can  take a  number  of  years  and  will  require  the  expenditure  of
substantial  resources by the Company.  Delays in obtaining  FDA approval  would
adversely  affect the  marketing of products to which the Company has rights and
the Company's ability to receive product revenues or royalties.  Moreover,  even
if FDA  approval is  obtained,  a marketed  product,  its  manufacturer  and its
manufacturing   facilities   are  subject  to  continual   review  and  periodic
inspections  by the FDA, and a later  discovery of previously  unknown  problems
with a product,  manufacturer  or facility  may result in  restrictions  on such
product  or  manufacturer.  Failure  to comply  with the  applicable  regulatory
requirements can, among other things, result in fines, suspensions of regulatory
approvals,  product recalls,  operating  restrictions and criminal  prosecution.
Additional government regulation may be established which could prevent or delay
regulatory approval of the Company's products.  Sales of pharmaceutical products
outside the United States are subject to foreign  regulatory  requirements  that
vary widely from country to country.  Even if FDA  approval  has been  obtained,
approval of a product by comparable regulatory  authorities of foreign countries
must be obtained  prior to the  commencement  of marketing  the product in those
countries.  The time  required to obtain such  approval may be longer or shorter
than  that  required  for  FDA  approval.  The  Company  has  no  experience  in
manufacturing or marketing in foreign  countries nor in matters such as currency
regulations, import-export controls or other trade laws.

RISKS INCIDENT TO PATENT APPLICATIONS AND RIGHTS

         The  Company's  success  will  depend in part on its  ability to obtain
patent  protection  for  products  and  processes  and to maintain  trade secret
protection and operate without  infringing the proprietary rights of others. The
degree of patent  protection  to be afforded to  pharmaceutical,  biomedical  or
medical  inventions is an uncertain  area of the law.  There can be no assurance
that the Company will develop or receive  sublicenses or other rights related to
proprietary  technology  which are  patentable,  that any patents  pending  will
issue,  or that any issued patents will provide the Company with any competitive
advantages or will not be challenged by third parties. Furthermore, there can

                                      -10-

<PAGE>
be no assurance that others will not independently  duplicate or develop similar
technologies to those developed by or licensed to the Company.

         The  Company  supports  and  collaborates  in  research   conducted  at
universities and other institutions.  There can be no assurance that the Company
will have or be able to acquire  exclusive  rights to  inventions  or  technical
information  derived from such collaborations or that disputes will not arise as
to such exclusive rights or any derivative or related research programs.  If the
Company is  required  to defend  against  charges of patent  infringement  or to
protect its own proprietary rights against third parties, substantial costs will
be  incurred  and  the  Company  could  lose  rights  to  certain  products  and
technologies.

RELIANCE ON THIRD PARTIES; NO MARKETING OR MANUFACTURING CAPABILITIES

         The Company does not intend to  manufacture  or market  products it may
develop  using  its  technologies.  The  Company  will  attempt  to  enter  into
manufacturing   and   marketing   agreements   with  one  or  more   established
pharmaceutical,  biomedical  and medical  companies  for any  products  that are
developed.  There can be no assurance that other  pharmaceutical,  biomedical or
medical  companies will be interested in the Company's  products or technologies
or be willing to enter  into  manufacturing  or  marketing  agreements  on terms
acceptable   to  the  Company.   Further,   there  can  be  no  assurance   that
pharmaceutical,   biomedical  or  other  medical   companies   will  succeed  in
manufacturing  and marketing the Company's  products or technologies or that the
Company will derive revenues from its products or technologies.

DEPENDENCE UPON OBTAINING HEALTHCARE REIMBURSEMENT

         The Company's ability to commercialize human therapeutic and diagnostic
products  may  indirectly  depend in part on the extent to which  costs for such
products  and  technologies  are  reimbursed  by  private  health  insurance  or
government  health  programs.  The uncertainty  regarding  reimbursement  may be
especially  significant in the case of newly approved products.  There can be no
assurance  that  price  levels  will be  sufficient  to  provide a return to the
Company on its investment in new products and technologies.

ADEQUACY OF PRODUCT LIABILITY INSURANCE

         The  use  of the  Company's  proposed  products  and  processes  during
testing, and after approval,  may entail inherent risks of adverse effects which
could expose the Company to product liability  claims.  Product liability claims
could have a material adverse effect on the business and financial  condition of
the Company.  The Company plans to obtain, and plans to require its licensees to
obtain,   product  liability  insurance  at  an  appropriate  stage  of  product
development  and  commercialization.  There can be no assurance that the Company
and its licensees will be able to maintain or obtain adequate product  liability
insurance on  acceptable  terms or that such  insurance  will  provide  adequate
coverage against all potential claims.

VOLATILITY OF MARKET PRICE OF SECURITIES

         The market price of securities of firms in the  biotechnology  industry
has tended to be volatile.  Announcements  of  technological  innovations by the
Company  or its  competitors,  developments  concerning  proprietary  rights and
concerns  about safety and other factors may have a material  adverse  effect on
the Company's  business or financial  condition.  The market price of the Common
Stock may be  significantly  affected by  announcements  of  developments in the
medical field generally or the Company's research areas specifically.  The stock
market has experienced  volatility in market prices of companies  similar to the
Company  that  has  often  been  unrelated  to the  operating  results  of  such
companies.  This  volatility  may have a material  adverse  effect on the market
price of the Common Stock.

OUTSTANDING OPTIONS AND WARRANTS; DILUTION

         As of April 30, 1997, the Company had reserved approximately  4,400,000
shares of Common Stock for issuance  upon  exercise of  outstanding  options and
warrants, including shares of Common Stock issuable upon the exercise of options
and  warrants  held by officers and  directors  of the Company.  The Company has
filed  registration  statements  with the  Commission  covering  the  resale  of
substantially  all of the shares of Common  Stock  underlying  such  options and
warrants.  The exercise of options and outstanding  warrants and sales of Common
Stock issuable thereunder could have a significant dilutive effect on the market
price of shares  of Common  Stock and  could  materially  impair  the  Company's
ability to raise capital through the future sale of its equity securities.

NO DIVIDENDS

         Holders of Common Stock are  entitled to receive such  dividends as may
be declared by the Board of Directors of the Company.  To date,  the Company has
not declared or paid any dividends on its Common Stock, and the Company does not
anticipate paying cash dividends in the foreseeable future.  Rather, the Company
intends to apply any earnings to the expansion and development of its business.

AUTHORIZATION OF SERIES A PREFERRED STOCK

         The Company's  Certificate of Incorporation  authorizes the issuance of
"blank check" preferred stock with such designations,  rights and preferences as
may be  determined  from  time  to  time  by the  Board  of  Directors,  without
shareholder  approval.  In the event of issuance,  such preferred stock could be
utilized, under certain circumstances, as a method of discouraging,  delaying or
preventing a change in control of the Company and preventing  shareholders  from
receiving a premium  for their  shares in  connection  with a change of control.
Except for the issuance of shares of Series A Preferred  Stock that  occurred in
connection with the  consummation  of a private  placement in February 1997, the
Company has no present  intention  to issue any shares of its  preferred  stock;
however,  there can be no assurance  that the Company will not issue  additional
shares of its preferred stock in the future.

EXERCISE OF SERIES A WARRANTS AND CONVERSION OF SERIES A PREFERRED STOCK

         Certain of the Selling  Stockholders  hold Series A Warrants  entitling
such Selling  Stockholders  to acquire a total of 351,539 shares of Common Stock
at an  exercise  price  of $3.65  per  share,  subject  to  adjustment  upon the
occurrence  of certain  events.  Certain of the Selling  Stockholders  also hold
35,700 shares of Series A Preferred  Stock that are  convertible  into shares of
Common Stock. See "Selling Stockholders." Each share of Series A Preferred Stock
may be  converted  after  May 29,  1997 at  varying  rates  of  conversion.  The
conversion rate will be adjusted, and the number of shares beneficially owned by
the Selling Stockholder will vary, to reflect changes in the market price of the
Common Stock, stock dividends, stock splits and certain other circumstances. For
a further  description of the rights of holders of Series A Preferred Stock, see
the  Certificate of Designation  of Series A Cumulative  Convertible  Redeemable
Preferred  Stock  filed as an exhibit  to the  Company's  Annual  Report on Form
10-KSB for the fiscal year ended  December  31,  1996.  The exercise of Series A
Warrants, the conversion of such shares of Series A Preferred Stock and the sale
of such shares of Common Stock could have a significant  negative  effect on the
market  price of the Common  Stock and could  materially  impair  the  Company's
ability to raise capital through the future sale of equity securities.

                                 USE OF PROCEEDS

         The Company  will  receive the  exercise  price of options and warrants
pursuant to which certain  shares of Common Stock offered hereby will be issued.
The Company  intends to use such exercise price proceeds for working capital and
general corporate  purposes.  The Company will not receive any proceeds from the
offer and resale of the Common Stock offered hereby.


                                 DIVIDEND POLICY

         Holders of Common Stock are  entitled to receive such  dividends as may
be declared by the Board of  Directors  of the  Company.  The Company  presently
intends  to  retain  earnings,  if any,  for use in its  business  and  does not
anticipate  paying  dividends  (other than stock dividends  payable on shares of
Series A Preferred  Stock) on its  outstanding  capital stock in the foreseeable
future.  Future  payments  of cash  dividends  will  depend  upon the  financial
condition, results of operations and capital requirements of the Company as well
as other factors deemed relevant by the Board of Directors.


                               RECENT DEVELOPMENTS

         On April 25,  1997,  Camelot  Pharmacal,  L.L.C.,  a  Missouri  limited
liability company ("Camelot"), merged with and into CP Pharmaceuticals,  Inc., a
newly formed subsidiary of the Company. The principals of Camelot at the time of
the merger were Loren G. Peterson, Carl F. Siekmann and David A. Byron. Pursuant
to the related  agreement  and plan of merger,  Messrs.  Peterson,  Siekmann and
Byron each received  200,000 shares of Common Stock.  Following the consummation
of the  merger,  each of  Messrs.  Peterson,  Siekmann  and Byron  entered  into
employment  agreements with Sheffield and received stock options  providing each
individual  the right to  purchase  up to 400,000  shares of Common  Stock.  The
Company has agreed to reimburse  Messrs.  Peterson,  Siekmann and Byron upon the
occurrence  of certain  events for  certain  income  taxes  payable by them upon
exercise of their stock  options in an amount of up to $250,000  per person.  In
connection with the merger,  Anthony B. Alphin,  Jr., Bernard  Laurent,  Stephen
Sohn and Michael  Zeldin  resigned as Directors of the Company and Mr.  Peterson
was elected a Director of the Company.

         voting  and  investment  power  with  respect  to all  shares  shown as
         beneficially  owned by them,  subject to community  property laws where
         applicable and the information contained in the footnotes hereunder.

(2)      Determined in accordance with Rule 13-3(d) of the Exchange Act.

(3)      Assumes all shares of Common Stock offered  hereby are sold pursuant to
         the registration statement of which the prospectus constitutes a part.

(4)      The number of shares of Common Stock issuable upon conversion of Series
         A Preferred  Stock and in respect of stock dividends  issuable  thereon
         will vary based upon the market value of the Company's  publicly-traded
         Common Stock prior to the date of conversion.  For a description of the
         method of  determining  the number of shares of Common  Stock  issuable
         upon conversion of shares of Series A Preferred Stock, see "Description
         of  Securities - Series A Preferred  Stock."  Consequently,  due to the
         fluctuating conversion rate of the Series A Preferred Stock, the number
         of shares of Common Stock that a holder of Series A Preferred Stock may
         receive upon conversion and sale pursuant to this Prospectus may exceed
         the number of shares of Common Stock such holder  beneficially  owns as
         determined  pursuant  to  Section  13-3(d)  of the  Exchange  Act.  For
         purposes  of the  disclosure  of  Shares  Beneficially  Owned  Prior to
         Offering,  it has been assumed (i) that the applicable conversion price
         will be $3.31875 (calculated in accordance with the applicable terms of
         the Series A Preferred Stock as of the date of issuance of the Series A
         Preferred Stock on February 28, 1997), (ii) that all shares of Series A
         Preferred  Stock  beneficially  owned by the  Selling  Stockholder  are
         converted  into  shares of  Common  Stock at such  conversion  price in
         accordance with the applicable  terms of the Series A Preferred  Stock,
         (iii)  that all  Series A Warrants  beneficially  owned by the  Selling
         Stockholder  have been  exercised  for shares of Common  Stock and (iv)
         that all Common Stock dividends  accrued and payable in accordance with
         the terms of the Series A Preferred Stock as of May 29, 1997 (the first
         day  such  stock  dividends  may be  issuable  in  accordance  with the
         applicable terms of the Series A Preferred Stock) have been issued. For
         purposes  of the  disclosure  of Shares  Beneficially  Owned  After the
         Offering,  it has been assumed that the applicable Selling  Stockholder
         (x) has converted all shares of Series A Preferred  Stock  beneficially
         owned by it into  shares of Common  Stock and has  received  all Common
         Stock issuable as Common Stock dividends on such Series A Preferred

                            DESCRIPTION OF SECURITIES

         The  Company is  currently  authorized  to issue  30,000,000  shares of
Common Stock,  $.01 par value per share, of which 11,988,274  shares were issued
and  outstanding  on the  date of  this  Prospectus,  and  3,000,000  shares  of
preferred  stock,  $.01 par value per share,  of which 35,700 shares of Series A
Preferred Stock were issued and outstanding on the date of this Prospectus.

COMMON STOCK

         Holders of shares of Common Stock are entitled to one vote per share on
all matters to be voted on by  shareholders  and do not have  cumulative  voting
rights.  Subject  to the rights of  holders  of  outstanding  shares of Series A
Preferred Stock and other holders of preferred stock of the Company, if any, the
holders of Common Stock are entitled to receive such  dividends,  if any, as may
be declared from time to time by the Board of Directors in its  discretion  from
funds legally  available  therefor,  and upon  liquidation or  dissolution,  are
entitled to receive all assets available for  distribution to the  shareholders.
The Common Stock has no preemptive or other  subscription  rights, and there are
no conversion  rights of redemption or sinking fund  provisions  with respect to
such shares.  All of the  outstanding  shares of Common Stock are fully paid and
nonassessable.

PREFERRED STOCK

         The Board of Directors is authorized  to issue the  preferred  stock in
one  or  more  series  and  to  fix  the  rights,  preferences,  privileges  and
restrictions,  including the dividend rights,  conversion rights, voting rights,
rights  and  terms  of  redemption,  redemption  price  or  prices,  liquidation
preferences and the number of shares constituting any series

                                      -16-

<PAGE>

or the  designations  of such series,  without any further vote or action by the
stockholders.  The issuance of preferred  stock may have the effect of delaying,
deferring  or  preventing  a change in control of the  Company  without  further
actions of the  stockholders.  The issuance of  preferred  stock with voting and
conversion rights may adversely affect the voting power of the holders of Common
Stock,  including the loss of voting  control to others.  The Company has 35,700
shares  of its  Series  A  Preferred  Stock  outstanding  on the  date  of  this
Prospectus.

SERIES A PREFERRED STOCK

         THE  DESCRIPTION  OF THE SERIES A  PREFERRED  STOCK  PROVIDED  BELOW IS
QUALIFIED  IN ITS  ENTIRETY BY THE  RELATIVE  RIGHTS,  PREFERENCES,  PRIVILEGES,
POWERS AND RESTRICTIONS OF THE SERIES A PREFERRED STOCK SET FORTH IN THE FORM OF
CERTIFICATE OF DESIGNATION  FOR THE SERIES A PREFERRED STOCK INCLUDED IN EXHIBIT
4.2 TO THE  COMPANY'S  ANNUAL  REPORT ON FORM  10-KSB FOR THE FISCAL  YEAR ENDED
DECEMBER 31, 1996, WHICH IS INCORPORATED BY REFERENCE INTO THIS
PROSPECTUS.

         There are 37,500 shares of Series A Preferred  Stock  outstanding as of
the date of this Prospectus. Holders of Series A Preferred Stock have the right,
exercisable  commencing  May 29, 1997 and ending  February 28, 1999,  to convert
shares of Series A Preferred  Stock into shares of Common  Stock.  The number of
shares of Common Stock issuable upon conversion of Series A Preferred Stock will
equal  the  number of shares  of  Series A  Preferred  Stock to be so  converted
multiplied by a fraction,  the numerator of which is 100 and the  denominator of
which shall equal (a) $3.31875 in respect of conversions  occurring on or before
June 27,  1997,  (b) the lesser of (i)  $3.31875  and (ii) the  "current  market
price" per share of Common Stock as of the applicable conversion date in respect
of conversions occurring from June 28, 1997 to and including August 26, 1997 and
(c) the lesser of (i) $3.31875 and (ii) 85% of the  "current  market  price" per
share of  Common  Stock  as of the  applicable  conversion  date in  respect  of
conversions occurring after August 26, 1997, where "current market price" means,
with certain  exceptions,  the average of the closing bid prices of Common Stock
for the 10  consecutive  trading  days  ending the last  trading  day before the
applicable  conversion date.  Accrued stock dividends  payable in respect of the
Series A Preferred  Stock are payable at the time of  conversion.  Under certain
circumstances, cash is payable to holders of Series A Preferred Stock in lieu of
Common Stock.

TRANSFER AGENT

         The Company's  transfer agent for its currently  issued and outstanding
Common Stock is Harris Trust and Savings Bank, Houston, Texas.

                              PLAN OF DISTRIBUTION

         The Common Stock offered hereby may be offered from time to time on the
AMEX or on any other  securities  exchange on which Common Stock is listed or in
privately  negotiated  transactions,  at fixed  prices that may be  changed,  at
market  prices  prevailing  at the  time of  sale,  at  prices  related  to such
prevailing market prices or at privately negotiated prices. Selling Stockholders
may effect  such  transactions  by  selling  such  shares of Common  Stock to or
through  one or more  underwriters,  brokers,  dealers  or  agents  and all such
underwriters,  brokers,  dealers and agents may receive compensation in the form
of  discounts,   concessions,   or  commissions  from  stockholders  and/or  the
purchasers  of shares for whom such  broker-dealers  may act as agent or to whom
they  sell  as  principal,  or  both  (which  compensation  as  to a  particular
underwriter,   broker,   dealer  or  agent  might  be  in  excess  of  customary
commissions).

         Any  broker-dealer  acquiring Common Stock offered hereby may sell such
securities either directly, in its normal market-making  activities,  through or
to other  brokers on a principal or agency basis or to its  customers.  Any such
sales may be at prices then  prevailing on the AMEX,  at prices  related to such
prevailing  market  prices  or  at  negotiated  prices  to  its  customers  or a
combination  of such methods.  The Selling  Stockholders  and any  underwriters,
brokers,  dealers or agents that act in connection with the sale might be deemed
to be  "underwriters"  within the meaning of Section 2(11) of the Securities Act
and any commissions received by them and any profit on the resale

                                      -17-

<PAGE>
of  securities  as  principal  may be deemed to be  underwriting  discounts  and
commissions  under the  Securities  Act.  Any such  commissions,  as well as any
applicable transfer taxes, are payable by the applicable Selling Stockholder.

                                  LEGAL MATTERS

         The validity of the issuance of the securities being offered hereby has
been passed upon for the Company by Olshan  Grundman Frome & Rosenzweig LLP, New
York, New York. Daniel J. Gallagher,  an attorney at such firm, is the holder of

ITEM 15.          INDEMNIFICATION OF DIRECTORS AND OFFICERS.


                  Except as hereinafter set forth, there is no statute,  charter
provision,  by-law,  contract or other  arrangement  under which any controlling
person,  director or officer of the Corporation is insured or indemnified in any
manner against liability which he may incur in his capacity as such.

                  Article   TENTH   of   the   Corporation's    Certificate   of
Incorporation provides as follows:

                  The  Corporation  shall,  to the fullest  extent  permitted by
ss.145 of thE General Corporation Law of the State of Delaware,  as the same may
be amended and  supplemented,  indemnify  any and all persons whom it shall have
power to  indemnify  under  said  section  from and  against  any and all of the
expenses,  liabilities  or  other  matters  referred  to in or  covered  by said
section,  and the  indemnification  provided  for  herein  shall  not be  deemed
exclusive of any other rights to which those  indemnified  may be entitled under
any By-Law,  agreement,  vote of  stockholders  or  disinterested  directors  or
otherwise,  both as to  action  in his  official  capacity  and as to  action in
another  capacity  while holding such office,  and shall continue as to a person
who has ceased to be a director,  officer,  employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

                  Section  5.1 of the  By-laws of the  Corporation  provides  as
follows:

                  (a)  The   Corporation   shall   indemnify,   subject  to  the
requirements of subsection (d) of this Section, any person who was or is a party
or is  threatened  to be made a party to any  threatened,  pending or  completed
action,  suit  or  proceeding,   whether  civil,  criminal,   administrative  or
investigative  (other than an action by or in the right of the Corporation),  by
reason of the fact that he is or was a director,  officer,  employee or agent of
the  Corporation,  or is or was serving at the request of the  Corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by him in connection  with such action,  suit or proceeding if he acted
in good faith and in a manner he reasonably  believed to be in or not opposed to
the best interests of the  Corporation  and, with respect to any criminal action
or proceeding,  had no reasonable cause to believe his conduct was unlawful. The
termination of any action,  suit or proceeding by judgment,  order,  settlement,
conviction or upon a plea of nolo  contendere or its  equivalent,  shall not, of
itself, create a

                                      II-1

<PAGE>
presumption  that the person did not act in good faith and in a manner  which he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
Corporation  and,  with  respect  to any  criminal  action  or  proceeding,  had
reasonable cause to believe that his conduct was unlawful.

                  (b)  The   Corporation   shall   indemnify,   subject  to  the
requirements of subsection (d) of this Section, any person who was or is a party
or is  threatened  to be made a party to any  threatened,  pending or  completed
action or suit by or in the right of the  Corporation  to procure a judgment  in
its favor by reason of the fact that he is or was a director,  officer, employee
or  agent  of  the  Corporation  or is or was  serving  at  the  request  of the
Corporation as a director,  officer,  employee or agent of another  corporation,
partnership,   joint  venture,  trust  or  other  enterprise,  against  expenses
(including   attorneys'  fees)  actually  and  reasonably  incurred  by  him  in
connection  with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the  Corporation and except that no  indemnification  shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the Corporation unless and only to the extent that
the Court of Chancery of the State of Delaware or the court in which such action
or  suit  was  brought  shall  determine  upon  application  that,  despite  the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and  reasonably  entitled to indemnity for such expenses  which
the Court of  Chancery  of the State of  Delaware or such other court shall deem
proper.

                  (c) To the extent that a director,  officer, employee or agent
of the  Corporation,  or a person serving in any other enterprise at the request
of the Corporation, has been successful on the merits or otherwise in defense of
any action,  suit or proceeding  referred to in  subsection  (a) and (b) of this
Section,  or in defense of any claim,  issue or matter therein,  the Corporation
shall indemnify him against  expenses  (including  attorneys' fees) actually and
reasonably incurred by him in connection therewith.

                  (d) Any indemnification  under subsections (a) and (b) of this
Section  (unless  ordered by a court) shall be made by the  Corporation  only as
authorized in the specific case upon a determination that indemnification of the
director,  officer,  employee or agent is proper in the circumstances because he
has met the applicable  standard of conduct set forth in subsections (a) and (b)
of this Section.  Such determination shall be made (1) by the Board of Directors
by a majority  vote of a quorum  consisting of directors who were not parties to
such action, suit or proceeding, or (2) if such a quorum is not obtainable,  or,
even if obtainable a quorum of  disinterested  directors,  or (3) by independent
legal counsel in a written opinion, or (4) by the stockholders.

                  (e)  Expenses  incurred  by a director,  officer,  employee or
agent in defending a civil or criminal action, suit or proceeding may be paid by
the  Corporation  in advance of the final  disposition  of such action,  suit or
proceeding  as  authorized  by  the  Board  of  Directors  upon  receipt  of  an
undertaking by or on behalf of the director, officer, employee or agent to repay
such amount if it shall  ultimately be determined  that he is not entitled to be
indemnified by the Corporation as authorized in this Section.

                  (f) The  indemnification  and advancement of expenses provided
by or granted pursuant to, the other subsections of this Section shall not limit
the  Corporation  from  providing any other  indemnification  or  advancement of
expenses  permitted by law nor shall it be deemed  exclusive of any other rights
to which  those  seeking  indemnification  may be  entitled  under  any  by-law,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his official  capacity and as to action in another  capacity  while
holding such office.

                  (g) The  Corporation  may purchase  and maintain  insurance on
behalf of any person who is or was a director, officer, employee or agent of the
Corporation,  or who is or was  serving at the request of the  Corporation  as a
director, officer, employee or agent of another corporation, partnership, joint

                                      II-2

<PAGE>
venture,  trust or other enterprise  against any liability  asserted against him
and incurred by him in any such capacity,  or arising out of his status as such,
whether or not the  Corporation  would have the power to  indemnify  him against
such liability under the provisions of this Section.

                  (h) The  indemnification  and advancement of expenses provided
by, or granted pursuant to this section shall,  unless  otherwise  provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer,  employee  or agent  and  shall  inure  to the  benefit  of the  heirs,
executors and administrators of such a person.

                  (i)  For the  purposes  of this  Section,  references  to "the
Corporation"  shall  include,  in addition  to the  resulting  corporation,  any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued,  would
have had power and authority to indemnify its directors,  officers, employees or
agents, so that any person who is or was a director,  officer, employee or agent
of such  constituent  corporation,  or is or was  serving at the request of such
constituent  corporation  as a director,  officer,  employee or agent of another
corporation,  partnership, joint venture, trust or other enterprise, shall stand
in the same  position  under the  provisions of this Section with respect to the
resulting  or  surviving  corporation  as he would  have  with  respect  to such
constituent corporation if its separate existence had continued.

                  (j)  This   Section  5.1  shall  be   construed  to  give  the
Corporation the broadest power  permissible by the Delaware General  Corporation
Law, as it now stands and as heretofore amended.

                  Section  145 of the  General  Corporation  Law of the State of
Delaware provides as follows:


                  (a) A  corporation  may  indemnify  any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative  (other than an action by or in the right of the  corporation)  by
reason of the fact that he is or was a director,  officer,  employee or agent of
the  corporation,  or is or was serving at the request of the  corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by him in connection  with such action,  suit or proceeding if he acted
in good faith and in a manner he reasonably  believed to be in or not opposed to
the best interests of the corporation,  and, with respect to any criminal action
or proceeding,  had no reasonable cause to believe his conduct was unlawful. The
termination of any action,  suit or proceeding by judgment,  order,  settlement,
conviction,  or upon a plea of nolo contendere or its equivalent,  shall not, of
itself,  create a presumption that the person did not act in good faith and in a
manner  which  he  reasonably  believed  to be in or not  opposed  to  the  best
interests  of the  corporation,  and,  with  respect to any  criminal  action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

                  (b) A  corporation  may  indemnify  any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed  action or suit by or in the  right of the  corporation  to  procure a
judgment  in its  favor  by  reason  of the fact  that he is or was a  director,
officer,  employee  or agent of the  corporation,  or is or was  serving  at the
request of the corporation as a director,  officer, employee or agent of another
corporation,  partnership,  joint  venture,  trust or other  enterprise  against
expenses (including  attorneys' fees) actually and reasonably incurred by him in
connection  with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the  corporation and except that no  indemnification  shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be

                                      II-3

<PAGE>

liable  to the  corporation  unless  and only to the  extent  that the  Court of
Chancery or the court in which such action or suit was brought  shall  determine
upon application that,  despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably  entitled to
indemnity  for such  expenses  which the Court of  Chancery  or such other court
shall deem proper.

                  (c) To the extent that a director,  officer, employee or agent
of a  corporation  has been  successful on the merits or otherwise in defense of
any action,  suit or proceeding  referred to in subsections  (a) and (b) of this
section,  or in  defense  of any  claim,  issue or matter  therein,  he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

                  (d) Any indemnification  under subsections (a) and (b) of this
section  (unless  ordered by a court) shall be made by the  corporation  only as
authorized in the specific case upon a determination that indemnification of the
director,  officer,  employee or agent is proper in the circumstances because he
has met the applicable  standard of conduct set forth in subsections (a) and (b)
of this section.  Such determination shall be made (1) by the board of directors
by a majority  vote of a quorum  consisting of directors who were not parties to
such action, suit or proceeding, or (2) if such a quorum is not obtainable,  or,
even  if  obtainable  a  quorum  of  disinterested   directors  so  directs,  by
independent legal counsel in a written opinion, or (3) by the stockholders.

                  (e)  Expenses  (including  attorneys'  fees)  incurred  by  an
officer  or  director  in  defending  any  civil  criminal   administrative   or
investigative  action,  suit or  proceeding  may be paid by the  corporation  in
advance of the final disposition of such action, suit or proceeding upon receipt
of an  undertaking  by or on behalf of such  director  or  officer to repay such
amount  if it shall  ultimately  be  determined  that he is not  entitled  to be
indemnified  by the  corporation  as authorized  in this section.  Such expenses
(including  attorneys'  fees)  incurred by other  employees and agents may be so
paid upon such terms and  conditions,  if any, as the board of  directors  deems
appropriate.

                  (f) The  indemnification  and advancement of expenses provided
by, or granted  pursuant to, the other  subsections of this section shall not be
deemed exclusive of any other rights to which those seeking  indemnification  or
advancement  of expenses  may be entitled  under any bylaw,  agreement,  vote of
stockholders or disinterested  directors or otherwise,  both as to action in his
official  capacity  and as to action in  another  capacity  while  holding  such
office.

                  (g) A  corporation  shall have power to purchase  and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director.  officer, employee or agent of another corporation,  partnership,
joint venture,  trust or other enterprise against any liability asserted against
him and  incurred by him in any such  capacity,  or arising out of his status as
such,  whether  or not the  corporation  would have the power to  indemnify  him
against such liability under this section.

                  (h)  For  purposes  of  this   section,   references  to  "the
corporation"  shall  include,  in addition  to the  resulting  corporation,  any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued,  would
have had power and authority to indemnify its directors, officers, and employees
or agents,  so that any person who is or was a  director,  officer,  employee or
agent of such  constituent  corporation,  or is or was serving at the request of
such  constituent  corporation  as a  director,  officer,  employee  or agent of
another  corporation,  partnership,  joint venture,  trust or other  enterprise,
shall  stand in the  same  position  under  this  section  with  respect  to the
resulting  or  surviving  corporation  as he would  have  with  respect  to such
constituent corporation if its separate existence had continued.

                  (i)  For  purposes  of  this  section,  references  to  "other
enterprises"  shall include employee benefit plans;  references to "fines" shall
include  any excise  taxes  assessed on a person  with  respect to any  employee
benefit  plan;  and  references  to "serving at the request of the  corporation"
shall  include  any  service as a  director,  officer,  employee or agent of the
corporation  which imposes  duties on, or involves  services by, such  director.
officer,  employee,  or agent with  respect to an  employee  benefit  plan,  its
participants  or  beneficiaries;  and a person  who acted in good faith and in a
manner he  reasonably  believed to be in the  interest of the  participants  and
beneficiaries  of an  employee  benefit  plan shall be deemed to have acted in a
manner "not opposed to the best interests of the  corporation" as referred to in
this section.

                  (j) The  indemnification  and advancement of expenses provided
by, or granted pursuant to, this section shall,  unless otherwise  provided when
authorized or ratified, continue as to a person who has ceased to be a director,
officer,  employee  or agent  and  shall  inure  to the  benefit  of the  heirs,
executors and administrators of such a person.

                  The  Company  maintains  a directors  and  officers  liability
insurance policy for coverage of up to $5,000,000.

ITEM 17.          UNDERTAKINGS.

         (a)      Rule 415

                  The undersigned registrant will:

                  (1)  File,  during  any  period  in which it  offers  or sells
securities, a post-effective amendment to this Registration Statement to include
any additional or changed material information on the plan of distribution.

                  (2) For determining  liability under the Securities Act, treat
each  such  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  to remove from  registration any of
the securities that remain unsold at the end of the offering.

(h)      Request for Acceleration of Effective Date

         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 small business  issuer pursuant to the foregoing  provisions,  or
otherwise, the small business issuer 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 small business issuer of expenses incurred or paid by a director, officer or
controlling person of the small business issuer 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.

         The undersigned registrant hereby undertakes that:

                  (1) For  purposes  of  determining  any  liability  under  the
         Securities  Act, the  information  omitted from the form of  prospectus
         filed as part of a  registration  statement in reliance  upon Rule 430A
         and  contained  in a form of  prospectus  filed by the  small  business
         issuer pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities
         Act shall be deemed to be part of this registration statement as of the
         time it was declared effective.

                  (2) For the purpose of  determining  any  liability  under the
         Securities Act, each  post-effective  amendment that contains a form of
         prospectus shall be deemed to be a new  registration  statement for the
         securities offered in the registration  statement,  and the offering of
         such  securities  at that time shall be deemed to be the  initial  bona
         fide offering thereof.

Ladies and Gentlemen:

                  Reference  is made to the  Registration  Statement on Form S-3
dated the date hereof (the  "Registration  Statement") filed with the Securities
and Exchange  Commission  by  Sheffield  Medical  Technologies  Inc., a Delaware
corporation (the "Company"). The Registration Statement relates to the resale of
an aggregate of 3,797,483  shares of Common  Stock,  $.01 par value (the "Common

dividends  payable on such  shares of Series A  Preferred  Stock;  (ii)  351,539

Common Stock  issuable upon exercise of a common stock warrant  granted to Brean
Murray & Co. (the "Brean Murray  Warrants");  (v) 222,922 shares of Common Stock
issuable  upon exercise of certain  common stock options  granted by the Company
(collectively, the "Stock Options").

                  We  advise  you  that we have  examined  originals  or  copies
certified or otherwise  identified to our  satisfaction  of the  Certificate  of
Incorporation and By-laws of the Company and minutes of meetings of the Board of
Directors of the Company and such other documents,  instruments and certificates
of officers and representatives of the Company and public officials, and we have
made such examination of the law, as we have deemed appropriate as the basis for
the opinion hereinafter expressed.  In making such examination,  we have assumed
the genuineness of all signatures,  the authenticity of all documents  submitted
to us as  originals,  and the  conformity  to original  documents  of  documents
submitted to us as certified or photostatic copies.

                  Based  upon  the  foregoing,  we are of the  opinion  that the
Shares,  when  issued  in  accordance  with  the  terms  and  conditions  of the
respective agreements or instruments  governing such issuance,  will be duly and
validly issued, fully paid and non-assessable.

                  We are members of the Bar of the State of New York and, except
as stated below, we express no opinion as to the laws of any jurisdiction  other
than the State of New York and the federal laws of the United States of America.

                  We consent  to the  reference  to this firm under the  caption
"Legal  Matters" in the prospectus that  constitutes a part of the  Registration
Statement.

                  We advise  you that  Daniel J.  Gallagher,  a partner  of this
firm, holds options to purchase 15,000 shares of Common Stock.

                                  Very truly yours,

The Board of Directors
Sheffield Medical Technologies Inc.:


We consent to incorporation by reference in the Registration Statement (Form S-3

11, 1994, relating to the consolidated financial statements of Sheffield Medical
Technologies Inc. and subsidiary included in the Annual Report (Form 10-KSB) for
the year ended December 31, 1996.

Our report dated  February  11, 1994,  contains an  explanatory  paragraph  that
states  that the  Company's  recurring  losses and net  deficit  position  raise
substantial  doubt  about  its  ability  to  continue  as a going  concern.  The
consolidated  financial  statements  do not include any  adjustments  that might
result from the outcome of this uncertainty.
