                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1997
                                   (UNAUDITED)



1.          CONSOLIDATED FINANCIAL STATEMENTS

            The  accompanying  consolidated  balance sheets as of March 31, 1997
            and December 31, 1996 and the accompanying  consolidated  statements
            of  operations  and cash flows for the three  months ended March 31,
            1997 and 1996 and for the period from  October 17, 1986  (inception)
            to  March  31,  1997,  have  been  prepared  by  Sheffield   Medical
            Technologies Inc. (the "Company"),  without audit. In the opinion of
            management,  all adjustments  (consisting  only of normal  recurring
            accruals)  necessary  to  present  fairly  the  financial  position,
            results of  operations,  and changes in cash flows at March 31, 1997
            and for all periods presented have been made.

            Certain  information and footnote  disclosures  normally included in
            financial  statements prepared in accordance with generally accepted
            accounting   principles  have  been  condensed  or  omitted.  It  is
            suggested that these  consolidated  financial  statements be read in
            conjunction with the financial statements and notes thereto included
            in the  Company's  annual  report on Form  10-KSB for the year ended
            December 31, 1996.  The results of  operations  for the three months
            ended March 31, 1997 and 1996 are not necessarily  indicative of the
            operating results for the full years.

            The Company was  incorporated on October 17, 1986,  under the Canada
            Business  Corporations Act. The Company's  wholly-owned  subsidiary,
            U-Tech Medical Corporation  ("U-Tech") was incorporated in the state
            of Texas on January 13, 1992 and is inactive at March 31,  1997.  On
            January 10, 1996, Ion Pharmaceuticals,  Inc., a Delaware corporation
            ("Ion"), was formed as a wholly-owned  subsidiary of the Company. At
            that time,  Ion  acquired the  Company's  rights with respect to its
            anti-proliferative   technology.   Unless   the   context   requires
            otherwise,  Sheffield,  U-Tech  and  Ion  are  referred  to as  "the
            Company". The Company commenced its biotechnology  operations in the
            United  States in January 1992 under new  management  and  Sheffield
            became  domesticated  as a Wyoming  corporation  in May 1992. At the
            Annual  Meeting of  shareholders  of the Company held on January 26,
            1995,   the   Company's   shareholders   approved  the  proposal  to
            reincorporate  the Company in  Delaware,  which was effected on June
            13, 1995. All significant  intercompany  transactions are eliminated
            in consolidation.

            The  Company  is in the  development  stage  and as  such  has  been
            principally  engaged in licensing and research efforts.  The Company
            has  generated  minimal  operating  revenue and requires  additional
            capital, which the Company intends to obtain through equity and debt
            offerings to continue to operate its business. The Company's ability
            to meet its  obligations  as they  become due and to  continue  as a
            going   concern  must  be  considered  in  light  of  the  expenses,
            difficulties  and delays  frequently  encountered  in starting a new
            business,  particularly  since the Company  will focus on  research,
            development  and  unproven  technology  which may  require a lengthy
            period of time and substantial expenditures to complete. Even if the
            Company  is  able  to   successfully   develop   new   products   or
            technologies,  there can be no assurance  the Company will  generate
            sufficient  revenues from the sale or licensing of such products and
            technologies  to  be  profitable.   Management   believes  that  the
            Company's  ability to meet its obligations as they become due and to
            continue as a going concern through December 1997 are dependent upon
            obtaining additional financing.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1997
                                   (UNAUDITED)


2.          NET LOSS PER COMMON SHARE

            Net loss  per  common  share  is based on net loss for the  relevant
            period  divided by the weighted  average number of shares issued and
            outstanding during the period. Stock options,  common stock issuable
            upon  conversion  of warrants  and common  stock  issuable  upon the
            conversion of cumulative  convertible redeemable preferred stock are
            not reflected as their effect would be antidilutive for both primary
            and fully diluted earnings per share computations.

            In February 1997, the Financial  Accounting  Standards  Board issued
            Statement  No.  128,  EARNINGS  PER SHARE,  which is  required to be
            adopted on December  31,  1997.  At that time,  the Company  will be
            required to change the method currently used to compute earnings per
            share and to restate all prior periods.  The impact of Statement 128
            on the  calculation of primary and fully diluted  earnings per share
            is not expected to be material.



3.          PRIVATE PLACEMENT

            On February  28, 1997, the Company completed a private  placement of
            35,700 shares of its 7% Series A Cumulative  Convertible  Redeemable
            Preferred Stock (the "Series A Preferred Stock"), which raised total
            gross  proceeds of $3.5  million.  The proceeds of this offering are
            being used to fund research and development,  patent prosecution and
            for working capital and general  corporate  purposes,  including the
            possible  acquisition of rights in new technologies in the Company's
            ordinary course of business.

            Dividends on the Series A Preferred  Stock are  cumulative  from the
            date of original  issue at an annual rate of 7% per share payable in
            common stock on the date of each  conversion at the then  applicable
            conversion  rate. The Series A Preferred  Stock is redeemable by the
            holders  under  certain  circumstances  through  February  28, 1999.
            Holders of Series A  Preferred  Stock also have the right to convert
            any or all shares of Series A Preferred  Stock into shares of common
            stock at a defined  conversion rate ending on February 28, 1999. The
            Series A Preferred  Stock had a  liquidation  value of $3,570,000 at
            March 31, 1997.



4.          SUPPLY AND LICENSE AGREEMENTS

            In March 1997,  the Company  exercised  its option and entered  into
            exclusive supply and license agreements for the world-wide rights to
            the  multi-dose   inhaler  technology  (MSI)  of  Siemens  A.G.  The
            agreements call for Siemens to be the exclusive  supplier of the MSI
            system, a hand-held, portable pulmonary deliverysystem.  The Company
            paid a license fee of $1.1 million in April 1997 to Siemens pursuant
            to its  agreements  and is required to make  additional  payments to
            Siemens of DM 2.0 million on January 1, 1998 and 1999.



5.          SUBSEQUENT EVENT

            On April 25, 1997, the Company acquired Camelot  Pharmacal,  L.L.C.,
            of St. Louis,  Missouri,  a privately  held emerging  pharmaceutical
            company.   The  members  of  Camelot's  management  team  have  been
            appointed officers of the Company and Loren G. Peterson, a principal
            of Camelot,  has been named Chief  Executive  Officer of the Company
            and has joined the Company's Board of Directors.  Consideration  for
            this  transaction  was 600,000  shares of Company  common stock.  In
            addition,  the  members  of the  Camelot  management  team have been
            granted options to acquire 1.2 million common shares  exercisable at
            market price as of the date of grant.

ITEM 2:

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



The Company,  being a development stage  enterprise,  has incurred a net loss in
each of the  fiscal  years  since its  inception  and has had to rely on outside
sources of funds to maintain its  liquidity.  Substantial  operating  losses are
expected to be incurred  for the next several  years as the Company  expends its
resources  for product  acquisition,  sponsored  research  and  development  and
preclinical and clinical testing.

As a development  stage company without  significant  revenues,  the Company has
financed its technology  development activities and operations primarily through
public  and  private  offerings  of  securities,  from  which it has  raised  an
aggregate of approximately $28.4 million through March 31, 1997. On February 28,
1997, the company completed a private offering of 35,000 shares of its 7% Series
A Cumulative  Convertible  Redeemable  Preferred Stock, which raised total gross
proceeds of $3.5  million.  The proceeds of this offering are being used to fund
research and development, patent prosecution and for working capital and general
corporate  purposes,  including  the  possible  acquisition  of  rights  in  new
technologies in the Company's ordinary course of business.  Management estimates
that  based on its  successful  history of  raising  capital,  its plans to seek
additional  funds through planned  offerings and the continued focus on selling,
licensing  and  commercialization  of its  technologies,  the Company  will have
sufficient resources to fund its activities for at least the next twelve months.
There can be no assurance  that planned  securities  offerings will be completed
or, if not  completed as planned,  that other sources of capital can be obtained
in amounts  and upon terms  acceptable  to the Company  during the twelve  month
period. In the event that such funds are not available when needed,  the Company
would be required to reduce or delay its  funding of current  research  projects
and delay  making  commitments  for  future  research  projects.  The  Company's
operating  results have fluctuated  significantly  during each quarter since its
reorganization,  and the Company  anticipates  that such  fluctuations,  largely
attributable  to varying  sponsored  research and  development  commitments  and
expenditures, will continue into the foreseeable future.

The  Company  continues  to  conduct  scientific   research,   clinical  trials,
development, and intellectual property protection. During the three months ended
March 31, 1997, the Company funded $1.9 million for research and  development on
its projects of which $1.1 million  represents the license fee for entering into
exclusive  supply and license  agreements for the world-wide  rights to Siemens'
multi-dose inhaler (MSI). During the succeeding  12-month period,  approximately
$6.3 million in  additional  funding is projected to be incurred on clinical and
laboratory research and development.  Of this estimated funding of $6.3 million,
approximately  $150,000  is  expected  to be applied to the  HIV/AIDS  Vaccines,
$150,000 to the UGIF Technology-Prostate Cancer, $250,000 to the Membrane Attack
Complex  (MAC)/Complement  Technology,   $950,000  to  the  Ion  Pharmaceuticals
Technologies and $4,800,000 to the MSI.

In addition to clinical and laboratory research development, the Company expects
to incur ongoing costs in connection with its intellectual  property  protection
and patent  prosecution,  which costs are expected to approximate  $100,000 over
the next 12 months.

REVENUES AND EXPENSES

Revenues:

From  inception  through the period ended March 31, 1997, the Company has earned
sub-license revenue of $510,000 primarily from the sub-license agreement for its
liposome-CD4 technology.

From  inception  through the period ended March 31, 1997, the Company has earned
interest  income  of  $415,138  and an  extraordinary  item  from  gain on early
extinguishment  of debt of $42,787.  The Company's  ability to generate material
revenues is contingent on the successful  commercialization its technologies and
other  technologies which it may acquire,  followed by the successful  marketing
and  commercialization of such technologies through licenses,  joint ventures or
other arrangements.

Interest  income for the three months ended March 31, 1997 was $18,225  compared
to $16,515 for the same period  ended March 31,  1996.  The increase in interest
earned is attributable to an increase of cash invested in short-term investments
Except for the sub-license revenue mentioned above,  interest income represented
all of the Company's income in each of the prior periods.

Operating Expenses:

From  inception  through the period ended March 31, 1997,  the Company  incurred
$30,224,665  of operating  expenses.  Of the total  operating  expenses for that
period,  $17,461,234  were costs of research and  development  for the Company's
technologies.  The  remainder  of expenses  for the same  period  were  incurred
principally  as  consulting  costs,   costs  of  management,   legal  and  other
professional fees and expenses relating to the Company's  technologies,  and for
its completed and proposed  financing plans.  Research and development costs are
expected to remain high as the Company implements  later-stage research projects
of its  technologies  and such costs will  continue to be expensed for financial
reporting purposes.

Operating  expenses for the three months ended March 31, 1997,  were  $2,686,313
compared to $1,672,168 for the same period ended March 31, 1996. The increase in
research  and  development  expenses  was  primarily  due to the payment of $1.1
million for the acquisition of an exclusive supply and license agreement for the
world-wide rights to Siemens'  multi-dose inhaler (MSI). The increase in general
and  administrative  expenses was primarily due to increased salary expense as a
result of the additions to the Company's management team and higher professional
fees.

LIQUIDITY AND CAPITAL RESOURCES

In  February  1993,  the Company  conducted  its initial  United  States  public
offering of 833,334  Units,  each Unit  consisting of two shares of Common Stock
and one Redeemable  Common Stock Purchase  Warrant  exercisable for one share of
Common  Stock  at  a  price  of  $3.75,   subject  to   adjustment   in  certain
circumstances,  at any time until February 10, 1998 (the "public offering"). The
net  proceeds  of  the  public  offering  to  the  Company,   after  payment  of
Underwriter's   discounts   and   commissions,   non-accountable   expenses  and
reimbursable  expenses,  and  other  expenses  of  the  public  offering,   were
approximately  $4,190,000.  Also,  during fiscal year 1993, the Company received
$762,833 in total proceeds from the exercise of warrants.  In March 1994 a total
of  $3,121,164  was  received  from the  exercise  of 832,324  of the  Company's
Redeemable  Stock Purchase  Warrants.  Each such warrant was exercisable for one
share of Sheffield's Common Stock at an exercise price of $3.75.

In April 1995,  the Company  completed a private  placement of 410,075  units to
accredited  investors  at a price  of  $8.00  per unit  for  gross  proceeds  of
$3,280,600. Each such unit consists of two shares of the Company's common


                                       7

                        (a development stage enterprise)


stock and a warrant to purchase one share of common stock at a price of $5.00 at
any time to and including  February 10, 2000. The warrants are redeemable by the
Company  under  certain  circumstances.  In July 1995,  the Company  completed a
second  private  placement of 1,375,000  units at $4.00 per unit,  which grossed
$5,500,000.  Each such unit consists of one share of the Company's  common stock
and one warrant to purchase one share of common stock at a price of $4.50 at any
time from March 1, 1996 to and  including  February 10,  2000.  The warrants are
subject to redemption under certain conditions.

On April 30, 1996,  the Company  completed a warrant  discount  program  through
which the  Company  offered  holders of  warrants  issued in private  placements
completed in 1995 the  opportunity  to exercise such warrants at up to a 12 1/2%
discount  from the  actual  exercise  prices of such  warrants.  A total of $5.6
million was received from the exercise of such warrants and the related issuance
of 1,373,250 shares of common stock.

On February 28, 1997, the Company  completed a private offering of 35,000 shares
of its 7% Series A Cumulative  Convertible  Redeemable  Preferred  Stock,  which
raised total gross  proceeds of $3.5 million.  The proceeds of this offering are
being used to fund research and development,  patent prosecution and for working
capital and general corporate  purposes,  including the possible  acquisition of
rights in new technologies in the Company's ordinary course of business.

In March 1997,  the Company  exercised  its option and  entered  into  exclusive
supply and license  agreements for the world-wide rights to Siemens'  multi-dose
inhaler (MSI).  The agreements call for Siemens to be the exclusive  supplier of
the MSI system, a hand-held,  portable  pulmonary  delivery system.  The Company
paid  Siemens  a license  fee of $1.1  million  in April  1997  pursuant  to its
agreements  and is  required  to make  additional  payments of DM 2.0 million on
January 1, 1998 and 1999.

In addition to the potential commercialization of its technologies,  the Company
plans to seek  additional  funds  through  financings,  joint  ventures or other
commercial arrangements to obtain necessary working capital. It is not uncommon,
for  instance,  for a  third-party  commercial  partner  to enter into a license
agreement  with a  development  company,  on the merits of  successful  research
relating to a given  technology,  which would yield up-front royalty advances to
such company before market-ready products are developed. It is also not uncommon
for a  third-party  commercial  partner  to  enter  into  an  agreement  with  a
development  company whereby a third party will  contribute  funds in support of
the research and operating needs of such development  companies in consideration
for rights related to the technologies.

At March 31, 1997, the Company's  assets were $3.5 million of which $3.2 million
was cash and cash equivalents and marketable securities.

              Section  3.13  LEGAL  PROCEEDINGS,  CLAIMS,  INVESTIGATIONS,  ETC.
Except  as set  forth  on  Schedule  3.13,  there is no  legal,  administrative,
arbitration or other action or proceeding or governmental investigation pending,
or to the knowledge of Camelot,  threatened,  against  Camelot.  Camelot has not
been  informed  of any  violation  of or default  under,  any laws,  ordinances,
regulations,  judgments,  injunctions,  orders  or  decrees  (including  without
limitation,  any immigration  laws or  regulations)  of any court,  governmental
department,  commission, agency, instrumentality or arbitrator applicable to the
business of Camelot.  Camelot is not currently subject to any material judgment,
order,  injunction or decree of any court,  arbitral  authority,  administrative
agency or other governmental authority.

              Section 3.14  INSURANCE.  Camelot has  insurance  policies in such
amounts as the management of Camelot has  reasonably  determined to be necessary
in regard to its respective business properties, personnel or assets. Camelot is
not in default with respect to any provision  contained in any insurance policy,
and has not failed to give any notice or present any claim  under any  insurance
policy in due and timely  fashion.  Any such policies  shall have been delivered
prior to the  Closing  to the  Parent  and are in full  force  and  effect.  All
payments  with respect to such policies are current and Camelot has received any
notice threatening a suspension, revocation, modification or cancellation of any
such policy.

hereto is a description of each contract and commitment  (including contracts or
commitments pertaining to employment),  whether written or oral to which Camelot
is a party.  Each of the  contracts and  commitments  set forth in Schedule 3.15
hereto and each of the other material contracts and commitments to which Camelot
is a party,  is valid and existing,  in full force and effect and enforceable in
accordance  with its terms  (subject  to laws  affecting  creditors'  rights and
equitable  principles)  and there is no  material  default  or claim of  default
against Camelot or any notice of termination with respect thereto. To the extent
required thereby, Camelot has complied in all material respects


                                       9
<PAGE>
with all  requirements  of, and performed  all of its  obligations  under,  such
contracts and commitments.  In addition,  no other party to any such contract or
commitment is, to the best of Camelot's knowledge, in default under or in breach
of any  material  term or  provision  thereof,  and there exists no condition or
event which,  after notice or lapse of time or both, would constitute a material
default  by any  party to any such  contract  or  commitment.  Copies of all the
written documents and a synopsis of all oral contracts and commitments described
in Schedule 3.15 hereto have  heretofore  been made  available to the Parent and
are true and complete and include all  amendments  and  supplements  thereto and
modifications thereof to and including the date hereof.

              (b) Except as set forth in Schedule 3.15 hereto,  Camelot is not a
party to any oral or  written  (i)  agreement  with  any  consultant,  executive
officer or other key employee the benefits of which are contingent, or the terms
of which  are  materially  altered,  upon  the  occurrence  of the  transactions
contemplated by this Agreement,  or (ii) agreement or plan,  including any stock
option plan and the like, any of the benefits of which will be increased, or the
vesting of the benefits of which will be  accelerated,  by the occurrence of the
transactions contemplated by this Agreement.

              Section 3.16 CERTAIN TRANSACTIONS. Except as set forth in Schedule
3.16 hereto,  neither any Member nor any officer or any employee of Camelot, nor
any member of any such  person's  immediate  family is  presently a party to any
material  agreement or transaction with Camelot,  including without  limitation,
any contract, agreement or other arrangement (i) providing for the furnishing of
services by, (ii) providing for the rental of real or personal property from, or
(iii)  otherwise  requiring  payments to (other than for services as officers or
employees of Camelot), any such person or any corporation, partnership, trust or
other  entity  in  which  any  such  person  has  a  substantial  interest  as a
stockholder, officer, director, trustee or partner.

              Section 3.17 BROKER.  No broker,  finder or  investment  banker is
entitled to any brokerage or finder's fee or other commission in connection with
the transactions  contemplated  hereby based on the  arrangements  made by or on
behalf of Camelot or the Members.

              Section 3.18 ENVIRONMENTAL MATTERS. (a) Camelot is not the subject
of, or to the  knowledge of Camelot or the Members,  being  threatened to be the
subject of (i) any enforcement proceeding, or (ii) any investigation, brought in
either  case  under  any  Federal,  state  or  local  environmental  law,  rule,
regulation,  or  ordinance  at any time in effect or (iii) any third party claim
relating  to  environmental  conditions  on or off the  properties  of  Camelot.
Camelot has not been  notified  that it must obtain any permits and  licenses or
file documents for the operation of its


                                       10
<PAGE>
business under federal, state and local laws relating to pollution protection of
the  environment.  Except as set forth in Schedule 3.18 hereto,  Camelot has not
been notified of any  conditions  on or off the  properties of Camelot which may
give  rise to any  liabilities  of  Camelot  under any  Federal,  state or local
environmental  law, rule,  regulation or ordinance or as the result of any claim
of any third  party.  For the purposes of this Section  3.18,  an  investigation
shall  include,  but is not limited to, any written  notice  received by Camelot
that relates to the onsite or offsite disposal,  release,  discharge or spill of
any waste, waste water, pollutant or contaminants.

              (b) To  Camelot's  knowledge,  there are no toxic  wastes or other
toxic or hazardous  substances or materials,  pollutants  or  contaminants  that
Camelot  (or,  to  Camelot's  knowledge,  any  previous  occupant  of  Camelot's
facilities) has used, stored or otherwise held in or on any of the facilities of
Camelot.  Camelot has not  disposed of or arranged  (by  contract,  agreement or
otherwise)  for the disposal of any material or substance  that was generated or
used by Camelot at any off-site  location that has been or is listed or proposed
for  inclusion on any list  promulgated  by any  Governmental  Authority for the
purpose of  identifying  sites which pose a danger to health and safety.  To the
knowledge of Camelot and the Members there have been no  environmental  studies,
reports and analyses  made or prepared  relating to the  facilities  of Camelot.
Camelot has not installed any underground storage tanks in any of its facilities
and,  to the  best  of  Camelot's  and  the  Members'  knowledge,  none  of such
facilities contain any underground storage tanks.

              Section  3.19  COMPLIANCE  WITH LAW.  Camelot has  complied in all
material respects with all laws, rules,  regulations,  arbitral  determinations,
orders,  writs,  decrees and injunctions which are applicable to or binding upon
Camelot or its properties,  except where such failure would not cause an Camelot
Material Adverse Effect.

              Section 3.20 FULL  DISCLOSURE.  All  schedules and annexes to this
Agreement  (collectively,  "Documents")  delivered by or on behalf of Camelot or
any Member  pursuant to this  Agreement  are true and  complete in all  material
respects  and are  authentic.  No  representation  or warranty of Camelot or the
Members contained in this Agreement,  and no Document  furnished by or on behalf
of Camelot or the Members to the Parent pursuant to this Agreement,  contains an
untrue  statement of a material  fact or omits to state a material fact required
to be stated therein or necessary to make the statements made, in the context in
which made, not materially false or misleading.  The Members have advised Parent
that Camelot is a new,  development  stage entity,  without current  substantial
business operations or revenues in respect of its business.

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE MEMBERS

              Each Member hereby  represents  and warrants to the Parent and the
Acquisition Corp., as follows:

              Section 4.1 MEMBERS' INTERESTS. Such Member owns the percentage of
the  outstanding  Member  Interests of Camelot set forth opposite his name under
the column "Member Interests Held" on Schedule 1.7 hereto, free and clear of all
liens, claims or encumbrances.

              Section 4.2 AUTHORITY  RELATIVE TO AND VALIDITY OF THIS AGREEMENT.
This  Agreement  has  been  duly  executed  and  delivered  by such  Member  and
constitutes the legal, valid and binding  obligations of such Member enforceable
against  such  Member  in  accordance  with  its  terms,   except  (i)  as  such
enforceability  may  be  limited  by  or  subject  to  bankruptcy,   insolvency,
reorganization,  moratorium or other similar laws  affecting  creditors'  rights
generally,  (ii) as such obligations are subject to general principles of equity
and (iii) as rights to indemnity  may be limited by federal or state  securities
laws or by public  policy.  Neither the execution and delivery by this Agreement
nor the consummation of the transactions  contemplated  thereby will violate any
provision of law, any order of any court or other agency of  government,  or any
judgment, award or decree or any agreement or instrument to which such Member is
a party, or by which he or any of his properties or assets is bound or affected,
or  result  in a breach of or  constitute  (with due  notice or lapse of time or
both) a  default  under  any such  agreement  or  instrument,  or  result in the
creation  or  imposition  of any  lien,  charge  or  encumbrance  of any  nature
whatsoever upon any of the properties or assets of such Member.

              Section 4.3 BROKERS' OR FINDERS' FEES. All  negotiations  relative
to the this Agreement and the transactions contemplated hereby have been carried
out by such Member or the other Members  directly  with the Parent,  without the
intervention  of any person on behalf of the  Members,  in such manner as not to
give rise to any claim by any person against the Parent or Acquisition Corp. for
a finder's fee, brokerage commission or similar payment.

              Section 4.4 MEMBERS' ADDRESSES, ACCESS TO INFORMATION, EXPERIENCE,
ETC.

              (a)  The  address  set  forth  under  such  Member's  name  on the
signature  pages of this  Agreement is such Member's true and correct  business,
residence or domicile  address.  Such Member has received,  read and is familiar
with the  Parent's  Annual  Report on Form  10-KSB  for the  fiscal  year  ended
December 31, 1996 (the "1996 10-KSB"). Such Member has had an opportunity to ask
questions of


                                       12
<PAGE>

and receive answers from  representatives of the Parent concerning the terms and
conditions  of this  transaction.  Such Member has received  such  documentation
relating to Parent's business,  results of operations and financial condition as
such Member has deemed  necessary.  Such Member has  substantial  experience  in
evaluating  non-liquid  investments  such  as the  Merger  Consideration  and is
capable of evaluating the merits and risks of an investment in the Parent.

              (b) Such Member  acknowledges  that he has had an  opportunity  to
evaluate  all  information  regarding  the Parent as he has deemed  necessary or
desirable in connection  with the  transactions  contemplated by this Agreement,
has independently evaluated the transactions  contemplated by this Agreement and
has reached his own decision to enter into this Agreement.

              Section  4.5  ACCREDITED  INVESTOR;   PURCHASE  ENTIRELY  FOR  OWN
ACCOUNT.  Such  Member  is  an  "accredited  investor"  within  the  meaning  of
Regulation  D  promulgated  under the  Securities  Act of 1933,  as amended (the
"Securities  Act").  The Merger  Consideration  to be  received  by such  Member
pursuant to the terms hereof will be acquired for  investment  for such Member's
own  account,  not as a nominee  or agent,  and not with a view to the resale or
distribution of any part thereof. Such Member has no present plan or arrangement
to dispose of the Merger Consideration in any manner.

              Section 4.6 RESTRICTED  SECURITIES.  Such Member  understands that
the  Merger  Consideration  he is  receiving  is  characterized  as  "restricted
securities"  under the federal  securities  laws inasmuch as such securities are
being acquired in a transaction  not involving a public  offering and that under
such laws and  applicable  regulations  such  securities  may be resold  without
registration under the Securities Act only in certain limited circumstances.  In
this  regard,  Such  Member  represents  that  he  is  familiar  with  Rule  144
promulgated  under the Securities Act ("Rule 144"), as presently in effect,  and
understands the resale limitations imposed thereby and by the Securities Act.

              Section  4.7  LEGENDS.  It is  understood  that  the  certificates
evidencing  the shares of Parent Common  constituting  the Merger  Consideration
shall bear a legend substantially as follows:

              "THE  SECURITIES  REPRESENTED  BY THIS  CERTIFICATE  HAVE NOT BEEN
              REGISTERED  UNDER THE  SECURITIES  ACT OF 1933,  AS  AMENDED  (THE
              "ACT")  AND  MAY  NOT  BE  TRANSFERRED  UNTIL  (I) A  REGISTRATION
              STATEMENT  UNDER THE ACT SHALL HAVE BECOME  EFFECTIVE  WITH REGARD
              THERETO OR (II) IN THE OPINION OF COUNSEL REASONABLY  SATISFACTORY
              TO THE CORPORATION TO THE EFFECT THAT  REGISTRATION  UNDER THE ACT
              IS NOT REQUIRED IN CONNECTION WITH SUCH PROPOSED TRANSFER."


                                       13
<PAGE>
              The legend  referred  to above shall be removed by the Parent from
any  certificate  at such time as the  Parent  receives  an  opinion  of counsel
reasonably  satisfactory  to the  Parent to the effect  that such  legend is not
required in order to establish  compliance with any provisions of the Securities
Act, or at such time as the holder of such shares  satisfies the requirements of
Rule 144 under the Securities Act.

                                    ARTICLE V

                        REPRESENTATIONS AND WARRANTIES OF

standing under the laws of the State of Delaware. Each of Parent and Acquisition
Corp. have provided  Camelot with true and complete  copies of their  respective
certificate of  incorporation  (certified by the Secretary of State of Delaware)
and By-laws  (certified by the Secretary of the Parent) as in effect on the date
hereof.  Parent and Acquisition  Corp. have all corporate power and authority to
own,  operate  and  lease  their  properties  and to carry  on their  respective
businesses  as the same are now  being  conducted,  and are  duly  qualified  or
licensed to do business  and are in good  standing  as foreign  corporations  in
every  jurisdiction  in which the conduct of their  business or the ownership or
leasing of their  respective  properties  requires  them to be so  qualified  or
licensed, except where the failure to be so qualified or licensed,  individually
or in the  aggregate,  will not have a material  adverse effect on the business,
properties,  financial  condition or operations of Parent and Acquisition Corp.,
taken as a whole (a "Sheffield Material Adverse Effect"). Each of the Parent and
Acquisition Corp. has all necessary  corporate power and authority to enter into
this  Agreement,  to perform its  obligations  hereunder and to  consummate  the
transactions contemplated hereby.

              Section 5.2 EXECUTION AND DELIVERY. Neither Parent nor Acquisition
Corp.  are  required  to submit  any  notice,  report or other  filing  with any
Governmental Authority in connection with the execution, delivery or performance
of this  Agreement,  other than the filing of the certificate of merger referred

of the Parent and Acquisition Corp. and constitutes the legal, valid and binding
obligations of Parent and Acquisition Corp.  enforceable  against the Parent and
Acquisition   Corp.   in  accordance   with  its  terms,   except  (i)  as  such
enforceability  may be  limited by or  subject  to any  bankruptcy,  insolvency,
reorganization, moratorium


                                       14
<PAGE>


or other  similar  laws  affecting  creditors'  rights  generally,  (ii) as such
obligations  are subject to general  principles of equity and (iii) as rights to
indemnity  may be  limited  by  federal  or state  securities  laws or by public
policy.

shares of Series A Cumulative  Convertible Redeemable Preferred Stock are issued
and outstanding as of the date of this Agreement.

              Section 5.4 SEC REPORT; ABSENCE OF MATERIAL ADVERSE EFFECT. Parent
has made available to Camelot and the Members copies of the 1996 10-KSB as filed
with the Securities  and Exchange  Commission  (the "SEC").  As of its date, the
1996 10-KSB (including without limitation, any financial statements or schedules
included  therein)  did not  contain  any untrue  statement  of a material  fact
required  to be stated  therein  or  necessary  in order to make the  statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  Each of the consolidated  financial  statements included in the SEC
Reports  has been  prepared  from,  and are in  accordance  with,  the books and
records  of  the  Parent,  comply  in  all  material  respects  with  applicable
accounting  requirements and with the published rules and regulations of the SEC

notes  thereto)  and fairly  present in all material  respects the  consolidated
financial  condition,  results of operations  and cash flows of the Parent as of
the dates thereof and for the periods presented therein.  Parent had at December
31, 1996 no  material  liability  or  obligation  of any kind or manner,  either
liquidated,  unliquidated,  direct, accrued, absolute,  contingent or otherwise,
whether  due or to become  due which was not  accurately  reflected  in the 1996
10-KSB.

              Section  5.5 BROKER.  No broker,  finder or  investment  banker is
entitled to any brokerage or finder's fee or other commission in connection with
the transactions  contemplated  hereby based upon the arrangements made by or on
behalf of the Parent or Acquisition Corp.

              Section 5.6 AUTHORITY  RELATIVE TO THIS AGREEMENT.  Each of Parent
and  Acquisition  Corp.  has full  corporate  power and authority to execute and
deliver  this  Agreement  and to  assume  and  perform  all  of its  obligations
hereunder.  The execution and delivery of the this  Agreement by each the Parent
and Acquisition  Corp. and the  performance by Parent and  Acquisition  Corp. of
their  respective  obligations  hereunder  have  been duly  authorized  by their
respective  Boards of  Directors  and no  further  authorization  on the part of
Parent or Acquisition Corp. or their shareholders is


                                       15
<PAGE>
necessary  to  authorize  the  execution  and  delivery  by  them  of,  and  the
performance of their respective obligations under, this Agreement.

              Section 5.7 REQUIRED  FILINGS AND CONSENTS;  NO CONFLICT.  Neither
Parent nor Acquisition  Corp. is required to submit any notice,  report or other
filing  with any  Governmental  Authority  in  connection  with  the  execution,
delivery  or  performance  of  this  Agreement.  The  execution,   delivery  and
performance  of  this  Agreement  by  Acquisition   Corp.  and  Parent  and  the
consummation  of the  transactions  contemplated  hereby do not and will not (a)
conflict with or violate any law, regulation,  judgment, order or decree binding
upon Acquisition Corp. or Parent,  (b) conflict with or violate any provision of
their  certificates of incorporation or by-laws,  or (c) conflict with or result
in a breach of any  condition  or provision  of, or  constitute a default (or an
event which with notice or lapse of time or both would become a default)  under,
or result in the creation or imposition of any lien, charge or encumbrance upon,
any  properties  or  assets  of  Parent or  Acquisition  Corp.  pursuant  to any
indenture,  loan agreement,  mortgage, deed of trust, lease, contract,  license,
franchise or other agreement or instrument to which Parent or Acquisition  Corp.
is a party or which is or  purports  to be binding  upon  Parent or  Acquisition
Corp. or by which either of their  properties  are bound,  except for conflicts,
breaches,  defaults,  events of  default  or  impositions  that would not have a
Sheffield Material Adverse Effect.

              Section  5.8  ABSENCE OF CERTAIN  CHANGES  AND  EVENTS.  Except as
disclosed in the 1996 10-KSB,  since December 31, 1996, there has not been, with

Material Adverse Effect, (ii) any material damage,  destruction or loss (whether
or not covered by  insurance)  with respect to any assets or properties or (iii)
any change in accounting  principles or methods (except insofar as may have been
required  by a change in GAAP).  Except as  disclosed  in the 1996  10-KSB or in
Schedule 5.8 or as contemplated  by this Agreement,  Parent has not incurred any

title or valid  leasehold  rights (in the case of leased  property)  to all real
property and all personal property purported to be owned or leased by it or used

material respects with all laws, rules,  regulations,  arbitral  determinations,
orders,  writs,  decrees and injunctions which are applicable to or binding upon
Parent or its properties,  except where such failure would not cause a Sheffield
Material Adverse Effect.

the appropriate  taxing  authorities all Tax Returns  required to be filed by or
with  respect to Parent or such Tax Returns are  properly on  extension  and all

respects,  and (ii) paid in full or made adequate provisions for all Taxes shown
to be due on such Tax  Returns.  There are no liens for Taxes upon the assets of

may incur or become  subject to arising out of or due to any  inaccuracy  of any
representation  or the  breach of any  warranty  or  covenant  of Camelot or any
Member contained in this Agreement.  Subject to the limitations set forth below,
Camelot and the Members  jointly and  severally  agree to reimburse  the Parent,

              Section  9.4  THIRD  PARTY  CLAIMS.  In  order  for a  party  (the
"indemnified  party") to be entitled to any  indemnification  provided for under
this  Agreement in respect of, arising out of, or involving a claim or demand or
written notice made by any third party against the  indemnified  party (a "Third
Party  Claim") after the Closing Date,  such  indemnified  party must notify the
indemnifying  party (the  "indemnifying  party")  in writing of the Third  Party
Claim within 30 business days after receipt by such indemnified party of written
notice of the Third Party Claim;  provided  that the failure of any  indemnified
party to give  timely  notice  shall not  affect  his  right of  indemnification

<PAGE>
except to the extent the  indemnifying  party has actually  been  prejudiced  or
damaged  thereby.  If a Third Party Claim is made against an indemnified  party,
the  indemnifying  party  shall be  entitled,  if it so  chooses,  to assume the
defense thereof with counsel selected by the  indemnifying  party (which counsel
shall  be  reasonably   satisfactory  to  the  indemnified  party),  unless  the
indemnified  party  reasonably  concludes  that the assumption of control by the
indemnifying  party  creates  a risk  of a  significant  adverse  effect  on the
indemnified  party's business  operations,  in which case the indemnifying party
shall not be entitled  to assume the  defense  thereof and shall be freed of any
responsibility for indemnification thereunder. If the indemnifying party assumes
the defense of a Third Party Claim, the indemnified  party will cooperate in all
reasonable respects with the indemnifying party in connection with such defense,
and shall have the right to participate in such defense with counsel selected by
it. The fees and disbursements of such counsel, however, shall be at the expense
of the indemnified party; PROVIDED, HOWEVER, that in the case of any Third Party
Claim of which the  indemnifying  party has not  employed  counsel to assume the
defense,  the fees and  disbursements of such counsel shall be at the expense of
the indemnifying party.

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

              WHEREAS, the Corporation desires to employ and retain Executive as
its Executive Vice President - Scientific Affairs, upon the terms and subject to
the conditions of this Agreement; and

              NOW,  THEREFORE,  in  consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto agree as follows:

              1.  EMPLOYMENT  OF  EXECUTIVE.   The  Corporation  hereby  employs
Executive as its Executive Vice President - Scientific  Affairs,  to perform the
duties and responsibilities  traditionally  incident to such office,  subject at
all  times  to the  control  and  direction  of the  Board of  Directors  of the
Corporation.

              2. ACCEPTANCE OF EMPLOYMENT; OFFICES; TIME AND ATTENTION, ETC. (a)
Executive  hereby accepts such  employment and agrees that throughout the period
of his employment hereunder,  except as hereinafter provided, he will devote his
full business and  professional  time in utilizing his business and professional
expertise,  with proper attention,  knowledge and skills faithfully,  diligently
and to the best of his ability in furtherance of the business of the Corporation
and its  subsidiaries  and will  perform the duties  assigned to him pursuant to
Paragraph 1 hereof. As Executive Vice President - Scientific Affairs,  Executive
shall also  perform  such  specific  duties  and shall  exercise  such  specific
authority  related  to  the  management  of  the  day-to-day  operations  of the
Corporation and its subsidiaries as may be reasonably assigned to Executive from
time to time by the Board of Directors of the Corporation.

              (b) Executive  shall at all times be subject to, observe and carry
out such rules, regulations,  policies, directions and restrictions as the Board
of Directors of the Corporation  shall from time to time  establish.  During the
period of his employment hereunder, Executive shall not, directly or indirectly,
accept  employment or compensation  from, or perform services of any nature for,
any  business  enterprise  other  than  the  Corporation  and its  subsidiaries.
Notwithstanding  the  foregoing  in this  Paragraph  2,  Executive  shall not be
precluded from engaging in  recreational,  eleemosynary,  educational  and other
activities  which do not materially  interfere with his duties  hereunder during
vacations,  holidays  and other  periods  outside of business  hours.  

              (c) It is anticipated that the Corporation's  principal  executive
office (now located in New York City) shall be relocated



<PAGE>
to St. Louis,  Missouri but that Executive may be required to spend  substantial
amounts of time at locations in and outside of St. Louis,  Missouri  relating to
the business of the  Corporation  and its  subsidiaries.  It is understood  that
Executive  shall  continue to reside in the vicinity of St. Louis,  Missouri and
that the Corporation shall maintain an office in St. Louis,  Missouri,  which is
where  Executive  shall  maintain his  principal  office  until the  Corporation
relocates from New York City to St. Louis,  Missouri.  The Corporation agrees to
reimburse  Executive for his  reasonable  expenses,  including  hotel and travel
costs, associated with the Corporation's business. In addition, until completion
of  such   relocation,   it  is  understood   that  Executive  shall  visit  the
Corporation's  executive office in New York City on a regular basis for meetings
and to conduct  Corporation  business that is more appropriately  conducted from
such executive office.

              3.  TERM.  Except  as  otherwise  provided  herein,  the  term  of
Executive's  employment hereunder shall commence on the date of the consummation
of the  merger of  Camelot  Pharmacal,  L.L.C.,  a  Missouri  limited  liability
company,  with and into a  subsidiary  of the Company (the  "Merger")  and shall
continue  to and  including  April 25,  2002.  Notwithstanding  anything  to the
contrary contained in the Agreement,  this Agreement shall terminate and have no
force and effect in the event that the  Merger is not  consummated  on or before
June 6, 1997.  Unless  terminated  earlier in accordance  with the terms hereof,
this  Agreement  shall  automatically  be  extended  for one or more  additional
consecutive  one year terms  unless  either  party  notifies  the other party in
writing at least six months  before the end of the then current term  (including
the initial term) of its or his desire to terminate this Agreement. The last day
of the term of this Agreement  pursuant to this Paragraph 3 (including any early
termination  pursuant  to  the  terms  hereof)  is  referred  to  herein  as the
"Termination Date."

              4. COMPENSATION.  (a) As compensation for his services  hereunder,
the  Corporation  shall pay to Executive (i) a base annual salary at the rate of
$160,000,  payable in equal  installments  in accordance with the normal payroll
practices of the Corporation but in no event less frequently than  semi-monthly,
and (ii)  such  incentive  compensation  and  bonuses,  if any,  as the Board of
Directors of the  Corporation in its absolute  discretion may determine to award
Executive  (it  being  understood  that  this  Agreement  shall  in no  event be
construed to require the payment to Executive of any incentive  compensation  or
bonuses),  it being  understood that Executive shall be entitled to receive such
incentive  compensation  and bonuses  determined  on a basis  comparable  to the
incentive compensation and/or bonuses awarded to other executive officers of the
Corporation.  All compensation paid to Executive shall be subject to withholding
and other employment taxes imposed by applicable law.

              (b)  During  the  period  of  Executive's   employment  hereunder,
Executive  shall not be entitled to any  additional  compensation  for rendering
employment services to subsidiaries of


                                       2
<PAGE>
the  Corporation  or for serving in any office of the  Corporation or any of its
subsidiaries to which he is elected or appointed.

              (c) In the event that  Executive  is elected to the  Corporation's
Board of  Directors,  Executive  will  receive  compensation  and  benefits as a
director  of the  Corporation  consistent  with the  compensation  and  benefits
received by the  Corporation's  other  directors  who are also  employees of the
Corporation.

              5. STOCK OPTIONS. (a) As additional  compensation for his services
hereunder,  the  Corporation  shall  grant to  Executive  an  option  under  the
Corporation's  1993 Stock Option Plan (the "Plan") to acquire a total of 400,000
shares of the Corporation's common stock at an exercise price per share equal to
the  closing  sale price of the  Corporation's  common  stock as reported by the
American Stock Exchange on the date hereof,  with the terms of such option to be
evidenced by (i) one option letter  agreement in the form annexed as Exhibit "A"
hereto  ("Option  Letter A-1") being  exercisable  for 100,000  shares of Common
Stock,  (ii) one option  letter  agreement in the form annexed as Exhibit  "A-2"
hereto  ("Option  Letter A-2") being  exercisable  for 150,000  shares of Common
Stock and (iii) one option  letter  agreement in the form annexed as Exhibit "B"
hereto ("Option Letter B") being  exercisable for 150,000 shares of Common Stock
(such option letters being referred to  collectively  herein as the "Plan Option
Letters").

              (b) The Company  represents and warrants that there are sufficient
shares of Common Stock currently available under the Company's 1993 Stock Option
Plan (the "1993 Plan") to cover the shares of Common Stock issuable to Executive
upon exercise of Option Letter A-1.

              (c) In the event that the Company's  stockholders fail at the next
annual  meeting  of  stockholders  of the  Corporation  to  approve  both (i) an
amendment  increasing the number of shares available for the issuance of options
under  the Plan to an  amount at least  sufficient  to cover  all the  shares of
Common Stock issuable upon exercise of Option Letter A-2 and Option Letter B and
(ii) appropriate amendments to the Plan specifically confirming the right of the
Corporation's  Board of  Directors,  in the issuance of stock  options under the
Plan,  to  determine  provisions  regarding  terms of the exercise of such stock
options  (including  without  limitation,  the period of exercisability of stock
options  under the Plan upon  termination  of  employment  for cause or  without
cause) and provisions  regarding forfeiture of stock options under the Plan upon
termination of employment,  the Company agrees, upon receipt of a written demand
from  Executive,  to promptly amend the Plan Option Letters to provide for three
non-qualified  options outside the Plan having  substantially the same terms and
provisions of the Plan Stock Options.

              (d) In the event that (i) the Corporation is required to amend the
Plan Option Letters pursuant to Paragraph 5(c) or (ii) Executive's employment by
the Corporation is terminated (x) by the


                                       3
<PAGE>
Corporation for any reason other than for Cause, (y) by Executive as a result of
an  Employer  Breach or (z) by the  Corporation  by  reason  of the  Executive's
disability or death prior to the expiration of the options evidenced by the Plan
Option  Letters  and  Executive  is  required  after  such event to pay any U.S.
federal or state income and  withholding tax  (collectively,  "Income Taxes") on
any  income  recognized  by  Executive  arising  upon any  exercise  of  options
evidenced  by the Plan  Option  Letters,  the  Corporation  agrees to  reimburse
Executive the difference  between (A) the amount of Income Taxes Executive would
have been  required  to pay had the  income  recognized  on such  exercise  been
treated as a long term capital  gain and (B) the amount of Income Taxes  payable
by Executive in respect of such  exercise (the amount of such  difference  being
referred to as the "Tax  Difference" in respect of such exercise).  In computing
the Tax Difference, the amount of taxes payable by Executive shall be determined
by assuming that the income  recognized as a result of such exercise is taxed at
the highest  marginal  federal and state income tax rates applicable to ordinary
income. In addition,  the Corporation shall pay Executive an amount equal to the
Tax Difference arising in respect of such exercise multiplied by a fraction, the
numerator of which is 1 and the denominator of which is equal to 1 minus (i) the
highest marginal federal income tax rate (currently  39.6%) and (ii) the highest
marginal state income tax rate applicable to Executive,  in each case in respect
of ordinary income, in effect at the time of such exercise. Such amount shall be
paid by the  Corporation  within  ninety  (90)  days  after  any such  exercise.
Notwithstanding  anything to the  contrary in this  Agreement or the Plan Option
Letters, the Corporation shall have no obligation to pay Executive any amount in
excess of $250,000 in the  aggregate  in respect of its  obligations  under this
subparagraph.

              6.  ADDITIONAL  BENEFITS;  VACATION.  (a) In addition to such base
salary, Executive shall receive and be entitled to participate, to the extent he
is  eligible  under the terms and  conditions  thereof,  in any profit  sharing,
pension, retirement, hospitalization,  disability, medical service, insurance or
other employee benefit plan generally available to the executive officers of the
Corporation  that may be in  effect  from  time to time  during  the  period  of
Executive's  employment  hereunder.  The  Corporation  agrees to cover Executive
under  any  directors'  and  officers'   liability  policy   maintained  by  the
Corporation.

              (b)  Executive  shall be entitled to four (4) weeks' paid vacation
in respect of each 12-month period during the term of his employment  hereunder,
such vacation to be taken at times mutually agreeable to Executive and the Board
of Directors of the Corporation.

              (c) Executive  shall be entitled to recognize as holidays all days
recognized as such by the Corporation.

              7.  REIMBURSEMENT  OF EXPENSES.  The  Corporation  shall reimburse
Executive in accordance  with  applicable  policies of the  Corporation  for all
expenses reasonably incurred by him in


                                       4

connection with the performance of his duties  hereunder and the business of the
Corporation,  upon the submission to the Corporation of appropriate  receipts or
vouchers.

              8. RESTRICTIVE COVENANT. (a) In consideration of the Corporation's
entering  into this  Agreement,  Executive  agrees that during the period of his
employment  hereunder  and, in the event of termination of this Agreement (i) by
the  Corporation  upon Executive  becoming  Disabled (as that term is defined in
Paragraph 13 hereof), (ii) by the Corporation for Cause (as that term is defined
in Paragraph 14 hereof) or (iii) by Executive otherwise than for Employer Breach
(as that term is defined in  Paragraph 15 hereof),  for a further  period of six
months thereafter,  he will not (x) directly or indirectly own, manage, operate,
join,  control,  participate  in,  invest in,  whether as an officer,  director,
employee, partner, investor or otherwise, any business entity that is engaged in
a  directly  competitive  business  (as  hereinafter  defined)  to  that  of the
Corporation or any of its subsidiaries within the United States of America,  (y)
for  himself  or on behalf  of any other  person,  partnership,  corporation  or
entity,  call on any customer of the Corporation or any of its  subsidiaries for
the purpose of soliciting  away,  diverting or taking away any customer from the
Corporation  or its  subsidiaries,  or (z) solicit any person then engaged as an
employee,  representative,  agent,  independent  contractor  or otherwise by the
Corporation  or any of its  subsidiaries,  to terminate his or her  relationship
with the Corporation or any of its subsidiaries. For purposes of this Agreement,
the term "directly  competitive  business"  shall mean any business that is then
involved in the research, development, manufacturing or commercialization in any
way of any  product,  compound,  device or method  that  acts or  functions  by,
through or on the same active,  binding or receptor  site,  mechanism of action,
signaling pathway or channel as any product,  compound, device or method that is
or becomes a part of the  Corporation's  business or the  business of any of its
subsidiaries  during  Executive's  employment by the  Corporation  or any of its
subsidiaries.  Nothing  contained in this Agreement  shall be deemed to prohibit
Executive  from investing his funds in securities of an issuer if the securities
of such issuer are listed for trading on a national  securities  exchange or are
traded in the over-the-counter market and Executive's holdings therein represent
less  than  10% of the  total  number  of  shares  or  principal  amount  of the
securities of such issuer outstanding.

              (b) Executive acknowledges that the provisions of this Paragraph 8
are  reasonable and necessary for the  protection of the  Corporation,  and that
each provision,  and the period or periods of time,  geographic  areas and types
and scope of  restrictions  on the  activities  specified  herein  are,  and are
intended to be, divisible.  In the event that any provision of this Paragraph 8,
including any sentence,  clause or part hereof,  shall be deemed contrary to law
or invalid or unenforceable in any respect by a court of competent jurisdiction,
the  remaining  provisions  shall not be  affected,  but  shall,  subject to the
discretion of such court, remain in full force and effect.

              9. CONFIDENTIAL INFORMATION.

                 (a)  Executive  shall  hold  in a  fiduciary  capacity  for the
benefit of the Corporation and its subsidiaries  all  confidential  information,
knowledge and data relating to or concerned with its operations, sales, business
and affairs,  and he shall not, at any time during his employment  hereunder and
for two  years  thereafter,  use,  disclose  or  divulge  any such  information,
knowledge  or  data  to any  person,  firm  or  corporation  other  than  to the
Corporation and its subsidiaries or their respective  designees or except as may
otherwise be reasonably  required or desirable in  connection  with the business
and affairs of the Corporation and its subsidiaries.

                 (b) Notwithstanding  anything to the contrary contained herein,
Executive's  obligations  under  Paragraph  9(a)  hereof  shall not apply to any
information which:

              (i) becomes  rightfully known to Executive  subsequent or prior to
    his employment by the Corporation;

              (ii) is or becomes  available to the public other than as a result
    of wrongful disclosure by Executive;

              (iii) becomes available to Executive  subsequent to his employment
    by the Corporation on a  nonconfidential  basis from a source other than the
    Corporation  or its  agents  which  source  has a  right  to  disclose  such
    information; or

              (iv)  results  from  research and  development  and/or  commercial
    operations  at any time by or on  behalf  of any  person,  company  or other
    entity  with which or with whom  Executive  shall  become  associated  (in a
    manner  consistent  with the  terms  of this  Agreement)  subsequent  to his
    employment by the  Corporation  or its agents totally  independent  from any
    disclosure from the Corporation or its agents.

                   (c)  Notwithstanding   anything  to  the  contrary  contained
herein,  in the event that Executive  becomes legally  compelled to disclose any
confidential  information,  Executive will provide the  Corporation  with prompt
notice so that the Corporation may seek a protective order or other  appropriate
remedy. In the event that such protective order or other remedy is not obtained,
Executive  shall  furnish only such  confidential  information  which is legally
required to be disclosed.

              10. INTELLECTUAL  PROPERTY.  Any idea, invention,  design, written
material,  manual,  system,  procedure,  improvement,  development  or discovery
conceived,  developed, created or made by Executive alone or with others, during
the period of his  employment  hereunder  and  applicable to the business of the
Corporation  or  any  of  its   subsidiaries,   whether  or  not  patentable  or
registrable,  shall become the sole and exclusive property of the Corporation or
such  subsidiary.  Executive  shall disclose the same promptly and completely to
the Corporation and shall, during the period of his


                                       6
<PAGE>
employment  hereunder and at any time and from time to time hereafter at no cost
to Executive (i) execute all documents  reasonably  requested by the Corporation
for vesting in the  Corporation  or any of its  subsidiaries  the entire  right,
title and  interest in and to the same,  (ii) execute all  documents  reasonably
requested by the Corporation for filing and prosecuting  such  applications  for
patents, trademarks,  service marks and/or copyrights as the Corporation, in its
sole  discretion,  may desire to prosecute,  and (iii) give the  Corporation all
assistance  it  reasonably  requires,  including  the giving of testimony in any
suit,  action or  proceeding,  in order to  obtain,  maintain  and  protect  the
Corporation's right therein and thereto.

              11.  EQUITABLE  RELIEF.   The  parties  hereto   acknowledge  that
Executive's  services  are  unique  and  that,  in the  event of a  breach  or a
threatened  breach by Executive of any of his obligations  under Paragraphs 8, 9
or 10 this Agreement,  the Corporation shall not have an adequate remedy at law.
Accordingly,  in the event of any such breach or threatened breach by Executive,
the Corporation shall be entitled to such equitable and injunctive relief as may
be  available  to  restrain  Executive  and  any  business,  firm,  partnership,
individual,  corporation  or entity  participating  in such breach or threatened
breach from the  violation  of the  provisions  of  Paragraph 8, 9 or 10 hereof.
Nothing herein shall be construed as prohibiting the  Corporation  from pursuing
any other  remedies  available at law or in equity for such breach or threatened
breach,  including the recovery of damages and the immediate  termination of the
employment of Executive hereunder, if and to the extent permitted hereunder.

              12.   TERMINATION   OF  AGREEMENT;   TERMINATION   OF  EMPLOYMENT;
SEVERANCE;  SURVIVAL.  (a) This Agreement and Executive's  employment  hereunder
shall terminate upon the first to occur of the following: (i) Executive becoming
Disabled  (as that term is defined in  Paragraph  13 hereof);  (ii)  Executive's
death; (iii) termination of Executive's  employment by the Corporation for Cause
or pursuant to  subparagraph  (b) of this  Paragraph  12;  (iv)  termination  of
Executive's  employment  for  Employer  Breach and (v) the  termination  of this
Agreement  at the end of the  term of this  Agreement  on the  Termination  Date
pursuant to Paragraph 3.

                   (b)  Notwithstanding  anything to the  contrary  contained in
this Agreement, in the event of the termination of the Executive's employment by
the Corporation for any reason (other than for Cause), Executive shall be paid a
severance  payment equal to 75% of  Executive's  then current annual base salary
payable in nine equal monthly  installments,  with the first  installment  being
payable on the date  falling  two weeks after the date of such  termination  and
each  additional  installment  being paid every month after such date until such
severance is paid in full. In the event of such  termination of the  Executive's
employment by the Corporation (other than for Cause), the Corporation shall have
no further  obligation  to the  Executive  under this  Agreement  other than the
Corporation's  obligation  (i) to make such  severance  payment to the Executive
(ii) to pay Executive's COBRA premium payments for


                                       7
<PAGE>
hospitalization  and medical insurance  coverage provided by the Corporation and
to pay  Executive's  premiums on any death  and/or  disability  insurance  being
maintained by the Corporation for Executive at the time of such termination,  in
each case until the payment in full of such severance payments

                   (c)  Paragraph  5(c)  of this  Agreement  shall  survive  the
termination of Executive's  employment  hereunder  until the earlier to occur of
Executive's exercise of all of the stock options granted pursuant to paragraph 5
and the  expiration  of all such  stock  options  pursuant  to the Stock  Option
Letters.  Paragraphs 7, 8, 9, 10, 11 and 26 of this Agreement  shall survive the
termination  of  Executive's  employment  hereunder,   except  in  the  case  of
termination pursuant to Paragraph 15.

              13.  DISABILITY.  In  the  event  that  during  the  term  of  his
employment by the  Corporation  Executive shall become Disabled (as that term is
hereinafter  defined)  he shall  continue to receive the full amount of the base
salary to which he was theretofore  entitled for a period of six months after he
shall be deemed to have become Disabled (the "First Disability Payment Period").
If the First Disability  Payment Period shall end prior to the Termination Date,
Executive thereafter shall be entitled to receive salary at an annual rate equal
to 80% of his then  current  base  salary  for a  further  period  ending on the
earlier of (i) six months  thereafter or (ii) the Termination  Date (the "Second
Disability  Payment  Period").  Upon the  expiration  of the  Second  Disability
Payment Period,  Executive shall not be entitled to receive any further payments
on account of his base salary until he shall cease to be Disabled and shall have
resumed his duties  hereunder and provided that the  Corporation  shall not have
theretofore  terminated this Agreement as hereinafter provided.  The Corporation
may terminate  Executive's  employment  hereunder at any time after Executive is
Disabled, upon at least 10 days' prior written notice;  PROVIDED,  HOWEVER, that
such  termination  shall not relieve the Corporation from its obligation to make
the payments to Executive described above in this Paragraph 13. For the purposes
of this Agreement, Executive shall be deemed to have become Disabled when (x) by
reason of physical or mental  incapacity,  Executive  is not able to perform his
duties  hereunder  for a period  of 90  consecutive  days or for 120 days in any
consecutive  180-day  period or (y) when  Executive's  physician  or a physician
designated by the Corporation  shall have determined that Executive shall not be
able,  by reason of  physical  or mental  incapacity,  to perform a  substantial
portion of his duties  hereunder.  In the event that Executive shall dispute any
determination of his disability pursuant to clauses (x) or (y) above, the matter
shall be resolved by the determination of three physicians qualified to practice
medicine  in the United  States of  America,  one to be  selected by each of the
Corporation  and  Executive  and the  third  to be  selected  by the  designated
physicians.  If Executive  shall receive  benefits under any  disability  policy
maintained by the Corporation,  the Corporation  shall be entitled to deduct the
amount  equal to the  benefits  so received  from base salary that it  otherwise
would have been required to pay to Executive as provided above.

              14.  TERMINATION  FOR CAUSE.  The Corporation may at any time upon
written notice to Executive  terminate  Executive's  employment  for Cause.  For
purposes of this  Agreement,  the  following  shall  constitute  Cause:  (i) the
willful  and  repeated  failure of  Executive  to perform  any  material  duties
hereunder or gross  negligence of Executive in the  performance  of such duties,
and if such failure or gross negligence is susceptible to cure by Executive, the
failure to effect such cure within twenty (20) days after written notice of such
failure or gross  negligence  is given to  Executive;  (ii) except as  permitted
hereunder,  unexplained,  willful and regular  absences  of  Executive  from the
Corporation;  (iii) excessive use of alcohol or illegal drugs,  interfering with
the performance of Executives duties  hereunder;  (iv) indictment for a crime of
theft, embezzlement,  fraud, misappropriation of funds, other acts of dishonesty
or the violation of any law or ethical rule relating to Executive's  employment;
(v) indicted for any other felony or other crime  involving  moral  turpitude by
Executive;  or  (vi)  the  breach  by  Executive  of any of  the  provisions  of
paragraphs  8, 9 or 10 and if such breach is  susceptible  of cure by Executive,
the failure to effect such cure within twenty (20) days after written  notice of
such breach is given to  Executive.  For purposes of this  Agreement,  an action
shall  be  considered  "willful"  if  it is  done  intentionally,  purposely  or
knowingly,   distinguished  from  an  act  done  carelessly,   thoughtlessly  or
inadvertently.  In any such  event,  Executive  shall be entitled to receive his
base salary to and including the date of termination.

              15.  TERMINATION FOR EMPLOYER  BREACH.  Executive may upon written
notice to the Corporation  terminate this Agreement (including  paragraphs 8, 9,
10 and  11) in the  event  of the  breach  by the  Corporation  of any  material
provision of this  Agreement,  and if such breach is  susceptible  of cure,  the
failure to effect such cure within 20 days after  written  notice of such breach
is  given  to the  Corporation  (an  "Employer  Breach").  Executive's  right to
terminate  this  Agreement  under this  Paragraph 15 shall be in addition to any
other remedies  Executive may have under law or equity.  Paragraphs  2(d), 7 and
12(b) of this  Agreement  shall  survive the  termination  of this  Agreement by
Executive pursuant to this Paragraph 15.

              16. INSURANCE POLICIES.  The Corporation shall have the right from
time to time to purchase,  increase,  modify or terminate  insurance policies on
the life of Executive for the benefit of the Corporation, in such amounts as the
Corporation  shall determine in its sole  discretion.  In connection  therewith,
Executive  shall,  at such  time or times  and at such  place or  places  as the
Corporation may reasonably direct,  submit himself to such physical examinations
and execute and deliver such documents as the  Corporation  may reasonably  deem
necessary or desirable.

              17. ENTIRE AGREEMENT;  AMENDMENT.  This Agreement  constitutes the
entire  agreement of the parties  hereto,  and any prior  agreement  between the
Corporation  and  Executive  is  hereby  superseded  and  terminated   effective
immediately  and shall be without  further  force or  effect.  No  amendment  or
modification


                                       9
<PAGE>
himself shall be valid or binding unless made in writing and signed by the party
against whom enforcement thereof is sought.

              18. NOTICES. Any notice required, permitted or desired to be given
pursuant to any of the provisions of this Agreement shall be delivered in person
or sent by responsible  overnight  delivery  service or sent by certified  mail,
return receipt requested,  postage and fees prepaid,  if to the Corporation,  at
its  address  set  forth  above  to the  attention  of the  Corporation's  Chief
Financial Officer and, if to Executive,  at his address set forth above.  Either
of the  parties  hereto may at any time and from time to time change the address
to which notice shall be sent hereunder by notice to the other party given under
this Paragraph 18. Notices shall be deemed effective upon receipt.

              19. NO ASSIGNMENT; BINDING EFFECT. Neither this Agreement, nor the
right to receive any payments hereunder, may be assigned by either party without
the other party's prior written  consent.  This Agreement  shall be binding upon
Executive, his heirs, executors and administrators and upon the Corporation, its
successors and assigns.

              20.  WAIVERS.  No course of  dealing  nor any delay on the part of
either party in exercising any rights hereunder shall operate as a waiver of any
such  rights.  No waiver of any  default  or breach of this  Agreement  shall be
deemed a continuing waiver or a waiver of any other breach or default.

              21.  GOVERNING  LAW.  This  Agreement  shall  be  governed  by and
construed in accordance with the laws of the State of New York, except that body
of law relating to choice of laws.

              22. INVALIDITY. If any clause, paragraph,  section or part of this
Agreement  shall be held or  declared to be void,  invalid or  illegal,  for any
reason,  by any  court  of  competent  jurisdiction,  such  provision  shall  be
ineffective  but shall not in any way  invalidate  or affect  any other  clause,
paragraph, section or part of this Agreement.

              23.  FURTHER  ASSURANCES.  Each of the parties  shall execute such
documents  and take such other  actions as may be  reasonably  requested  by the

accordance with its terms.

              24. HEADINGS.  The headings  contained in this Agreement have been
inserted  for  convenience  only and shall not affect in any way the  meaning or
interpretation of this Agreement.

              25. PUBLICITY.  The Corporation and Executive agree that they will

execution  of this  Agreement  with  respect to the terms  contemplated  hereby,
except as required by applicable  law,  without the prior  approval of the other
party, which approval will not be unreasonably withheld.

                              EMPLOYMENT AGREEMENT

Sheffield Medical  Technologies Inc., a Delaware  corporation with its principal
offices at 30  Rockefeller  Plaza,  Suite  4515,  New York,  New York 10112 (the
"Corporation"), and Loren G. Peterson residing at 1776 Stifel Lane Drive, Town &
Country, Missiouri 63017 ("Executive").

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

              WHEREAS, the Corporation desires to employ and retain Executive as
its Chief  Executive  Officer,  upon the terms and subject to the  conditions of
this Agreement; and

              NOW,  THEREFORE,  in  consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto agree as follows:

              1.  EMPLOYMENT  OF  EXECUTIVE.   The  Corporation  hereby  employs
Executive  as  its  Chief   Executive   Officer,   to  perform  the  duties  and
responsibilities  traditionally incident to such office, subject at all times to
the control and direction of the Board of Directors of the Corporation.

              2. ACCEPTANCE OF EMPLOYMENT; OFFICES; TIME AND ATTENTION, ETC. (a)
Executive  hereby accepts such  employment and agrees that throughout the period
of his employment hereunder,  except as hereinafter provided, he will devote his
full business and  professional  time in utilizing his business and professional
expertise,  with proper attention,  knowledge and skills faithfully,  diligently
and to the best of his ability in furtherance of the business of the Corporation
and its  subsidiaries  and will  perform the duties  assigned to him pursuant to
Paragraph 1 hereof.  As Chief  Executive  Officer,  Executive shall also perform
such specific duties and shall exercise such specific  authority  related to the
management of the day-to-day  operations of the Corporation and its subsidiaries
as may be  reasonably  assigned to  Executive  from time to time by the Board of
Directors of the Corporation.

              (b) Executive  shall at all times be subject to, observe and carry
out such rules, regulations,  policies, directions and restrictions as the Board
of Directors of the Corporation  shall from time to time  establish.  During the
period of his employment hereunder, Executive shall not, directly or indirectly,
accept  employment or compensation  from, or perform services of any nature for,
any  business  enterprise  other  than  the  Corporation  and its  subsidiaries.
Notwithstanding  the  foregoing  in this  Paragraph  2,  Executive  shall not be
precluded from engaging in  recreational,  eleemosynary,  educational  and other
activities  which do not materially  interfere with his duties  hereunder during
vacations, holidays and other periods outside of business hours.

              (c) It is anticipated that the Corporation's  principal  executive
office (now located in New York City) shall be relocated


<PAGE>
to St. Louis,  Missouri but that Executive may be required to spend  substantial
amounts of time at locations in and outside of St. Louis,  Missouri  relating to
the business of the  Corporation  and its  subsidiaries.  It is understood  that
Executive  shall  continue to reside in the vicinity of St. Louis,  Missouri and
that the Corporation shall maintain an office in St. Louis,  Missouri,  which is
where  Executive  shall  maintain his  principal  office  until the  Corporation
relocates from New York City to St. Louis,  Missouri.  The Corporation agrees to
reimburse  Executive for his  reasonable  expenses,  including  hotel and travel
costs, associated with the Corporation's business. In addition, until completion
of  such   relocation,   it  is  understood   that  Executive  shall  visit  the
Corporation's  executive office in New York City on a regular basis for meetings
and to conduct  Corporation  business that is more appropriately  conducted from
such executive office.

              3.  TERM.  Except  as  otherwise  provided  herein,  the  term  of
Executive's  employment hereunder shall commence on the date of the consummation
of the  merger of  Camelot  Pharmacal,  L.L.C.,  a  Missouri  limited  liability
company,  with and into a  subsidiary  of the Company (the  "Merger")  and shall
continue  to and  including  April 25,  2002.  Notwithstanding  anything  to the
contrary contained in the Agreement,  this Agreement shall terminate and have no
force and effect in the event that the  Merger is not  consummated  on or before
June 6, 1997.  Unless  terminated  earlier in accordance  with the terms hereof,
this  Agreement  shall  automatically  be  extended  for one or more  additional
consecutive  one year terms  unless  either  party  notifies  the other party in
writing at least six months  before the end of the then current term  (including
the initial term) of its or his desire to terminate this Agreement. The last day
of the term of this Agreement  pursuant to this Paragraph 3 (including any early
termination  pursuant  to  the  terms  hereof)  is  referred  to  herein  as the
"Termination Date."

              4. COMPENSATION.  (a) As compensation for his services  hereunder,
the  Corporation  shall pay to Executive (i) a base annual salary at the rate of
$175,000,  payable in equal  installments  in accordance with the normal payroll
practices of the Corporation but in no event less frequently than  semi-monthly,
and (ii)  such  incentive  compensation  and  bonuses,  if any,  as the Board of
Directors of the  Corporation in its absolute  discretion may determine to award
Executive  (it  being  understood  that  this  Agreement  shall  in no  event be
construed to require the payment to Executive of any incentive  compensation  or
bonuses),  it being  understood that Executive shall be entitled to receive such
incentive  compensation  and bonuses  determined  on a basis  comparable  to the
incentive compensation and/or bonuses awarded to other executive officers of the
Corporation.  All compensation paid to Executive shall be subject to withholding
and other employment taxes imposed by applicable law.

              (b)  During  the  period  of  Executive's   employment  hereunder,
Executive  shall not be entitled to any  additional  compensation  for rendering
employment services to subsidiaries of


                                       2
<PAGE>
the  Corporation  or for serving in any office of the  Corporation or any of its
subsidiaries to which he is elected or appointed.

              (c) In the event that  Executive  is elected to the  Corporation's
Board of  Directors,  Executive  will  receive  compensation  and  benefits as a
director  of the  Corporation  consistent  with the  compensation  and  benefits
received by the  Corporation's  other  directors  who are also  employees of the
Corporation.

              5. STOCK OPTIONS. (a) As additional  compensation for his services
hereunder,  the  Corporation  shall  grant to  Executive  an  option  under  the
Corporation's  1993 Stock Option Plan (the "Plan") to acquire a total of 400,000
shares of the Corporation's common stock at an exercise price per share equal to
the  closing  sale price of the  Corporation's  common  stock as reported by the
American Stock Exchange on the date hereof,  with the terms of such option to be
evidenced by (i) one option letter  agreement in the form annexed as Exhibit "A"
hereto  ("Option  Letter A-1") being  exercisable  for 100,000  shares of Common
Stock,  (ii) one option  letter  agreement in the form annexed as Exhibit  "A-2"
hereto  ("Option  Letter A-2") being  exercisable  for 150,000  shares of Common
Stock and (iii) one option  letter  agreement in the form annexed as Exhibit "B"
hereto ("Option Letter B") being  exercisable for 150,000 shares of Common Stock
(such option letters being referred to  collectively  herein as the "Plan Option
Letters").

              (b) The Company  represents and warrants that there are sufficient
shares of Common Stock currently available under the Company's 1993 Stock Option
Plan (the "1993 Plan") to cover the shares of Common Stock issuable to Executive
upon exercise of Option Letter A-1.

              (c) In the event that the Company's  stockholders fail at the next
annual  meeting  of  stockholders  of the  Corporation  to  approve  both (i) an
amendment  increasing the number of shares available for the issuance of options
under  the Plan to an  amount at least  sufficient  to cover  all the  shares of
Common Stock issuable upon exercise of Option Letter A-2 and Option Letter B and
(ii) appropriate amendments to the Plan specifically confirming the right of the
Corporation's  Board of  Directors,  in the issuance of stock  options under the
Plan,  to  determine  provisions  regarding  terms of the exercise of such stock
options  (including  without  limitation,  the period of exercisability of stock
options  under the Plan upon  termination  of  employment  for cause or  without
cause) and provisions  regarding forfeiture of stock options under the Plan upon
termination of employment,  the Company agrees, upon receipt of a written demand
from  Executive,  to promptly amend the Plan Option Letters to provide for three
non-qualified  options outside the Plan having  substantially the same terms and
provisions of the Plan Stock Options.

              (d) In the event that (i) the Corporation is required to amend the
Plan Option Letters pursuant to Paragraph 5(c) or (ii) Executive's employment by
the Corporation is terminated (x) by the


                                       3
<PAGE>
Corporation for any reason other than for Cause, (y) by Executive as a result of
an  Employer  Breach or (z) by the  Corporation  by  reason  of the  Executive's
disability or death prior to the expiration of the options evidenced by the Plan
Option  Letters  and  Executive  is  required  after  such event to pay any U.S.
federal or state income and  withholding tax  (collectively,  "Income Taxes") on
any  income  recognized  by  Executive  arising  upon any  exercise  of  options
evidenced  by the Plan  Option  Letters,  the  Corporation  agrees to  reimburse
Executive the difference  between (A) the amount of Income Taxes Executive would
have been  required  to pay had the  income  recognized  on such  exercise  been
treated as a long term capital  gain and (B) the amount of Income Taxes  payable
by Executive in respect of such  exercise (the amount of such  difference  being
referred to as the "Tax  Difference" in respect of such exercise).  In computing
the Tax Difference, the amount of taxes payable by Executive shall be determined
by assuming that the income  recognized as a result of such exercise is taxed at
the highest  marginal  federal and state income tax rates applicable to ordinary
income. In addition,  the Corporation shall pay Executive an amount equal to the
Tax Difference arising in respect of such exercise multiplied by a fraction, the
numerator of which is 1 and the denominator of which is equal to 1 minus (i) the
highest marginal federal income tax rate (currently  39.6%) and (ii) the highest
marginal state income tax rate applicable to Executive,  in each case in respect
of ordinary income, in effect at the time of such exercise. Such amount shall be
paid by the  Corporation  within  ninety  (90)  days  after  any such  exercise.
Notwithstanding  anything to the  contrary in this  Agreement or the Plan Option
Letters, the Corporation shall have no obligation to pay Executive any amount in
excess of $250,000 in the  aggregate  in respect of its  obligations  under this
subparagraph.

              6.  ADDITIONAL  BENEFITS;  VACATION.  (a) In addition to such base
salary, Executive shall receive and be entitled to participate, to the extent he
is  eligible  under the terms and  conditions  thereof,  in any profit  sharing,
pension, retirement, hospitalization,  disability, medical service, insurance or
other employee benefit plan generally available to the executive officers of the
Corporation  that may be in  effect  from  time to time  during  the  period  of
Executive's  employment  hereunder.  The  Corporation  agrees to cover Executive
under  any  directors'  and  officers'   liability  policy   maintained  by  the
Corporation.

              (b)  Executive  shall be entitled to four (4) weeks' paid vacation
in respect of each 12-month period during the term of his employment  hereunder,
such vacation to be taken at times mutually agreeable to Executive and the Board
of Directors of the Corporation.

              (c) Executive  shall be entitled to recognize as holidays all days
recognized as such by the Corporation.

              7.  REIMBURSEMENT  OF EXPENSES.  The  Corporation  shall reimburse
Executive in accordance  with  applicable  policies of the  Corporation  for all
expenses reasonably incurred by him in


                                       4
<PAGE>
connection with the performance of his duties  hereunder and the business of the
Corporation,  upon the submission to the Corporation of appropriate  receipts or
vouchers.

              8. RESTRICTIVE COVENANT. (a) In consideration of the Corporation's
entering  into this  Agreement,  Executive  agrees that during the period of his
employment  hereunder  and, in the event of termination of this Agreement (i) by
the  Corporation  upon Executive  becoming  Disabled (as that term is defined in
Paragraph 13 hereof), (ii) by the Corporation for Cause (as that term is defined
in Paragraph 14 hereof) or (iii) by Executive otherwise than for Employer Breach
(as that term is defined in  Paragraph 15 hereof),  for a further  period of six
months thereafter,  he will not (x) directly or indirectly own, manage, operate,
join,  control,  participate  in,  invest in,  whether as an officer,  director,
employee, partner, investor or otherwise, any business entity that is engaged in
a  directly  competitive  business  (as  hereinafter  defined)  to  that  of the
Corporation or any of its subsidiaries within the United States of America,  (y)
for  himself  or on behalf  of any other  person,  partnership,  corporation  or
entity,  call on any customer of the Corporation or any of its  subsidiaries for
the purpose of soliciting  away,  diverting or taking away any customer from the
Corporation  or its  subsidiaries,  or (z) solicit any person then engaged as an
employee,  representative,  agent,  independent  contractor  or otherwise by the
Corporation  or any of its  subsidiaries,  to terminate his or her  relationship
with the Corporation or any of its subsidiaries. For purposes of this Agreement,
the term "directly  competitive  business"  shall mean any business that is then
involved in the research, development, manufacturing or commercialization in any
way of any  product,  compound,  device or method  that  acts or  functions  by,
through or on the same active,  binding or receptor  site,  mechanism of action,
signaling pathway or channel as any product,  compound, device or method that is
or becomes a part of the  Corporation's  business or the  business of any of its
subsidiaries  during  Executive's  employment by the  Corporation  or any of its
subsidiaries.  Nothing  contained in this Agreement  shall be deemed to prohibit
Executive  from investing his funds in securities of an issuer if the securities
of such issuer are listed for trading on a national  securities  exchange or are
traded in the over-the-counter market and Executive's holdings therein represent
less  than  10% of the  total  number  of  shares  or  principal  amount  of the
securities of such issuer outstanding.

              (b) Executive acknowledges that the provisions of this Paragraph 8
are  reasonable and necessary for the  protection of the  Corporation,  and that
each provision,  and the period or periods of time,  geographic  areas and types
and scope of  restrictions  on the  activities  specified  herein  are,  and are
intended to be, divisible.  In the event that any provision of this Paragraph 8,
including any sentence,  clause or part hereof,  shall be deemed contrary to law
or invalid or unenforceable in any respect by a court of competent jurisdiction,
the  remaining  provisions  shall not be  affected,  but  shall,  subject to the
discretion of such court, remain in full force and effect.

              9. CONFIDENTIAL INFORMATION.

                 (a)  Executive  shall  hold  in a  fiduciary  capacity  for the
benefit of the Corporation and its subsidiaries  all  confidential  information,
knowledge and data relating to or concerned with its operations, sales, business
and affairs,  and he shall not, at any time during his employment  hereunder and
for two  years  thereafter,  use,  disclose  or  divulge  any such  information,
knowledge  or  data  to any  person,  firm  or  corporation  other  than  to the
Corporation and its subsidiaries or their respective  designees or except as may
otherwise be reasonably  required or desirable in  connection  with the business
and affairs of the Corporation and its subsidiaries.

                 (b) Notwithstanding  anything to the contrary contained herein,
Executive's  obligations  under  Paragraph  9(a)  hereof  shall not apply to any
information which:

              (i) becomes  rightfully known to Executive  subsequent or prior to
     his employment by the Corporation;

              (ii) is or becomes  available to the public other than as a result
     of wrongful disclosure by Executive;

              (iii) becomes available to Executive  subsequent to his employment
     by the Corporation on a nonconfidential  basis from a source other than the
     Corporation  or its  agents  which  source  has a right  to  disclose  such
     information; or

              (iv)  results  from  research and  development  and/or  commercial
     operations  at any time by or on behalf  of any  person,  company  or other
     entity with which or with whom  Executive  shall  become  associated  (in a
     manner  consistent  with the  terms of this  Agreement)  subsequent  to his
     employment by the  Corporation or its agents totally  independent  from any
     disclosure from the Corporation or its agents.

                   (c)  Notwithstanding   anything  to  the  contrary  contained
herein,  in the event that Executive  becomes legally  compelled to disclose any
confidential  information,  Executive will provide the  Corporation  with prompt
notice so that the Corporation may seek a protective order or other  appropriate
remedy. In the event that such protective order or other remedy is not obtained,
Executive  shall  furnish only such  confidential  information  which is legally
required to be disclosed.

              10. INTELLECTUAL  PROPERTY.  Any idea, invention,  design, written
material,  manual,  system,  procedure,  improvement,  development  or discovery
conceived,  developed, created or made by Executive alone or with others, during
the period of his  employment  hereunder  and  applicable to the business of the
Corporation  or  any  of  its   subsidiaries,   whether  or  not  patentable  or
registrable,  shall become the sole and exclusive property of the Corporation or
such  subsidiary.  Executive  shall disclose the same promptly and completely to
the Corporation and shall, during the period of his


                                       6
<PAGE>
employment  hereunder and at any time and from time to time hereafter at no cost
to Executive (i) execute all documents  reasonably  requested by the Corporation
for vesting in the  Corporation  or any of its  subsidiaries  the entire  right,
title and  interest in and to the same,  (ii) execute all  documents  reasonably
requested by the Corporation for filing and prosecuting  such  applications  for
patents, trademarks,  service marks and/or copyrights as the Corporation, in its
sole  discretion,  may desire to prosecute,  and (iii) give the  Corporation all
assistance  it  reasonably  requires,  including  the giving of testimony in any
suit,  action or  proceeding,  in order to  obtain,  maintain  and  protect  the
Corporation's right therein and thereto.

              11.  EQUITABLE  RELIEF.   The  parties  hereto   acknowledge  that
Executive's  services  are  unique  and  that,  in the  event of a  breach  or a
threatened  breach by Executive of any of his obligations  under Paragraphs 8, 9
or 10 this Agreement,  the Corporation shall not have an adequate remedy at law.
Accordingly,  in the event of any such breach or threatened breach by Executive,
the Corporation shall be entitled to such equitable and injunctive relief as may
be  available  to  restrain  Executive  and  any  business,  firm,  partnership,
individual,  corporation  or entity  participating  in such breach or threatened
breach from the  violation  of the  provisions  of  Paragraph 8, 9 or 10 hereof.
Nothing herein shall be construed as prohibiting the  Corporation  from pursuing
any other  remedies  available at law or in equity for such breach or threatened
breach,  including the recovery of damages and the immediate  termination of the
employment of Executive hereunder, if and to the extent permitted hereunder.

              12.   TERMINATION   OF  AGREEMENT;   TERMINATION   OF  EMPLOYMENT;
SEVERANCE;  SURVIVAL.  (a) This Agreement and Executive's  employment  hereunder
shall terminate upon the first to occur of the following: (i) Executive becoming
Disabled  (as that term is defined in  Paragraph  13 hereof);  (ii)  Executive's
death; (iii) termination of Executive's  employment by the Corporation for Cause
or pursuant to  subparagraph  (b) of this  Paragraph  12;  (iv)  termination  of
Executive's  employment  for  Employer  Breach and (v) the  termination  of this
Agreement  at the end of the  term of this  Agreement  on the  Termination  Date
pursuant to Paragraph 3.

                   (b)  Notwithstanding  anything to the  contrary  contained in
this Agreement, in the event of the termination of the Executive's employment by
the Corporation for any reason (other than for Cause), Executive shall be paid a
severance  payment equal to 75% of  Executive's  then current annual base salary
payable in nine equal monthly  installments,  with the first  installment  being
payable on the date  falling  two weeks after the date of such  termination  and
each  additional  installment  being paid every month after such date until such
severance is paid in full. In the event of such  termination of the  Executive's
employment by the Corporation (other than for Cause), the Corporation shall have
no further  obligation  to the  Executive  under this  Agreement  other than the
Corporation's  obligation  (i) to make such  severance  payment to the Executive
(ii) to pay Executive's COBRA premium payments for


                                       7
<PAGE>
hospitalization  and medical insurance  coverage provided by the Corporation and
to pay  Executive's  premiums on any death  and/or  disability  insurance  being
maintained by the Corporation for Executive at the time of such termination,  in
each case until the payment in full of such severance payments

                   (c)  Paragraph  5(c)  of this  Agreement  shall  survive  the
termination of Executive's  employment  hereunder  until the earlier to occur of
Executive's exercise of all of the stock options granted pursuant to paragraph 5
and the  expiration  of all such  stock  options  pursuant  to the Stock  Option
Letters.  Paragraphs 7, 8, 9, 10, 11 and 26 of this Agreement  shall survive the
termination  of  Executive's  employment  hereunder,   except  in  the  case  of
termination pursuant to Paragraph 15.

              13.  DISABILITY.  In  the  event  that  during  the  term  of  his
employment by the  Corporation  Executive shall become Disabled (as that term is
hereinafter  defined)  he shall  continue to receive the full amount of the base
salary to which he was theretofore  entitled for a period of six months after he
shall be deemed to have become Disabled (the "First Disability Payment Period").
If the First Disability  Payment Period shall end prior to the Termination Date,
Executive thereafter shall be entitled to receive salary at an annual rate equal
to 80% of his then  current  base  salary  for a  further  period  ending on the
earlier of (i) six months  thereafter or (ii) the Termination  Date (the "Second
Disability  Payment  Period").  Upon the  expiration  of the  Second  Disability
Payment Period,  Executive shall not be entitled to receive any further payments
on account of his base salary until he shall cease to be Disabled and shall have
resumed his duties  hereunder and provided that the  Corporation  shall not have
theretofore  terminated this Agreement as hereinafter provided.  The Corporation
may terminate  Executive's  employment  hereunder at any time after Executive is
Disabled, upon at least 10 days' prior written notice;  PROVIDED,  HOWEVER, that
such  termination  shall not relieve the Corporation from its obligation to make
the payments to Executive described above in this Paragraph 13. For the purposes
of this Agreement, Executive shall be deemed to have become Disabled when (x) by
reason of physical or mental  incapacity,  Executive  is not able to perform his
duties  hereunder  for a period  of 90  consecutive  days or for 120 days in any
consecutive  180-day  period or (y) when  Executive's  physician  or a physician
designated by the Corporation  shall have determined that Executive shall not be
able,  by reason of  physical  or mental  incapacity,  to perform a  substantial
portion of his duties  hereunder.  In the event that Executive shall dispute any
determination of his disability pursuant to clauses (x) or (y) above, the matter
shall be resolved by the determination of three physicians qualified to practice
medicine  in the United  States of  America,  one to be  selected by each of the
Corporation  and  Executive  and the  third  to be  selected  by the  designated
physicians.  If Executive  shall receive  benefits under any  disability  policy
maintained by the Corporation,  the Corporation  shall be entitled to deduct the
amount  equal to the  benefits  so received  from base salary that it  otherwise
would have been required to pay to Executive as provided above.


                                       8
<PAGE>
              14.  TERMINATION  FOR CAUSE.  The Corporation may at any time upon
written notice to Executive  terminate  Executive's  employment  for Cause.  For
purposes of this  Agreement,  the  following  shall  constitute  Cause:  (i) the
willful  and  repeated  failure of  Executive  to perform  any  material  duties
hereunder or gross  negligence of Executive in the  performance  of such duties,
and if such failure or gross negligence is susceptible to cure by Executive, the
failure to effect such cure within twenty (20) days after written notice of such
failure or gross  negligence  is given to  Executive;  (ii) except as  permitted
hereunder,  unexplained,  willful and regular  absences  of  Executive  from the
Corporation;  (iii) excessive use of alcohol or illegal drugs,  interfering with
the performance of Executives duties  hereunder;  (iv) indictment for a crime of
theft, embezzlement,  fraud, misappropriation of funds, other acts of dishonesty
or the violation of any law or ethical rule relating to Executive's  employment;
(v) indicted for any other felony or other crime  involving  moral  turpitude by
Executive;  or  (vi)  the  breach  by  Executive  of any of  the  provisions  of
paragraphs  8, 9 or 10 and if such breach is  susceptible  of cure by Executive,
the failure to effect such cure within twenty (20) days after written  notice of
such breach is given to  Executive.  For purposes of this  Agreement,  an action
shall  be  considered  "willful"  if  it is  done  intentionally,  purposely  or
knowingly,   distinguished  from  an  act  done  carelessly,   thoughtlessly  or
inadvertently.  In any such  event,  Executive  shall be entitled to receive his
base salary to and including the date of termination.

              15.  TERMINATION FOR EMPLOYER  BREACH.  Executive may upon written
notice to the Corporation  terminate this Agreement (including  paragraphs 8, 9,
10 and  11) in the  event  of the  breach  by the  Corporation  of any  material
provision of this  Agreement,  and if such breach is  susceptible  of cure,  the
failure to effect such cure within 20 days after  written  notice of such breach
is  given  to the  Corporation  (an  "Employer  Breach").  Executive's  right to
terminate  this  Agreement  under this  Paragraph 15 shall be in addition to any
other remedies  Executive may have under law or equity.  Paragraphs  2(d), 7 and
12(b) of this  Agreement  shall  survive the  termination  of this  Agreement by
Executive pursuant to this Paragraph 15.

              16. INSURANCE POLICIES.  The Corporation shall have the right from
time to time to purchase,  increase,  modify or terminate  insurance policies on
the life of Executive for the benefit of the Corporation, in such amounts as the
Corporation  shall determine in its sole  discretion.  In connection  therewith,
Executive  shall,  at such  time or times  and at such  place or  places  as the
Corporation may reasonably direct,  submit himself to such physical examinations
and execute and deliver such documents as the  Corporation  may reasonably  deem
necessary or desirable.

              17. ENTIRE AGREEMENT;  AMENDMENT.  This Agreement  constitutes the
entire  agreement of the parties  hereto,  and any prior  agreement  between the
Corporation  and  Executive  is  hereby  superseded  and  terminated   effective
immediately  and shall be without  further  force or  effect.  No  amendment  or
modification


                                       9
<PAGE>
himself shall be valid or binding unless made in writing and signed by the party
against whom enforcement thereof is sought.

              18. NOTICES. Any notice required, permitted or desired to be given
pursuant to any of the provisions of this Agreement shall be delivered in person
or sent by responsible  overnight  delivery  service or sent by certified  mail,
return receipt requested,  postage and fees prepaid,  if to the Corporation,  at
its  address  set  forth  above  to the  attention  of the  Corporation's  Chief
Financial Officer and, if to Executive,  at his address set forth above.  Either
of the  parties  hereto may at any time and from time to time change the address
to which notice shall be sent hereunder by notice to the other party given under
this Paragraph 18. Notices shall be deemed effective upon receipt.

              19. NO ASSIGNMENT; BINDING EFFECT. Neither this Agreement, nor the
right to receive any payments hereunder, may be assigned by either party without
the other party's prior written  consent.  This Agreement  shall be binding upon
Executive, his heirs, executors and administrators and upon the Corporation, its
successors and assigns.

              20.  WAIVERS.  No course of  dealing  nor any delay on the part of
either party in exercising any rights hereunder shall operate as a waiver of any
such  rights.  No waiver of any  default  or breach of this  Agreement  shall be
deemed a continuing waiver or a waiver of any other breach or default.

              21.  GOVERNING  LAW.  This  Agreement  shall  be  governed  by and
construed in accordance with the laws of the State of New York, except that body
of law relating to choice of laws.

              22. INVALIDITY. If any clause, paragraph,  section or part of this
Agreement  shall be held or  declared to be void,  invalid or  illegal,  for any
reason,  by any  court  of  competent  jurisdiction,  such  provision  shall  be
ineffective  but shall not in any way  invalidate  or affect  any other  clause,
paragraph, section or part of this Agreement.

              23.  FURTHER  ASSURANCES.  Each of the parties  shall execute such
documents  and take such other  actions as may be  reasonably  requested  by the
other  party to carry out the  provisions  and  purposes  of this  Agreement  in
accordance with its terms.

              24. HEADINGS.  The headings  contained in this Agreement have been
inserted  for  convenience  only and shall not affect in any way the  meaning or
interpretation of this Agreement.

              25. PUBLICITY.  The Corporation and Executive agree that they will
not make any press  releases or other  announcements  prior to or at the time of
execution  of this  Agreement  with  respect to the terms  contemplated  hereby,
except as required by applicable  law,  without the prior  approval of the other
party, which approval will not be unreasonably withheld.

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

              WHEREAS, the Corporation desires to employ and retain Executive as
its Executive Vice President - Corporate Development, upon the terms and subject
to the conditions of this Agreement; and

              NOW,  THEREFORE,  in  consideration of the premises and the mutual
covenants hereinafter set forth, the parties hereto agree as follows:

              1.  EMPLOYMENT  OF  EXECUTIVE.   The  Corporation  hereby  employs
Executive as its Executive  Vice President - Corporate  Development,  to perform
the duties and responsibilities  traditionally  incident to such office, subject
at all times to the  control  and  direction  of the Board of  Directors  of the
Corporation.


              2. ACCEPTANCE OF EMPLOYMENT; OFFICES; TIME AND ATTENTION, ETC. (a)
Executive  hereby accepts such  employment and agrees that throughout the period
of his employment hereunder,  except as hereinafter provided, he will devote his
full business and  professional  time in utilizing his business and professional
expertise,  with proper attention,  knowledge and skills faithfully,  diligently
and to the best of his ability in furtherance of the business of the Corporation
and its  subsidiaries  and will  perform the duties  assigned to him pursuant to
Paragraph  1 hereof.  As  Executive  Vice  President  -  Corporate  Development,
Executive  shall also  perform  such  specific  duties and shall  exercise  such
specific authority related to the management of the day-to-day operations of the
Corporation and its subsidiaries as may be reasonably assigned to Executive from
time to time by the Board of Directors of the Corporation.

                  (b)  Executive  shall at all times be subject to,  observe and
carry out such rules, regulations,  policies, directions and restrictions as the
Board of Directors of the Corporation shall from time to time establish.  During
the  period of his  employment  hereunder,  Executive  shall  not,  directly  or
indirectly,  accept employment or compensation  from, or perform services of any
nature  for,  any  business  enterprise  other  than  the  Corporation  and  its
subsidiaries. Notwithstanding the foregoing in this Paragraph 2, Executive shall
not be precluded from engaging in  recreational,  eleemosynary,  educational and
other  activities  which do not materially  interfere with his duties  hereunder
during vacations, holidays and other periods outside of business hours.

<PAGE>
              (c) It is anticipated that the Corporation's  principal  executive
office (now located in New York City) shall be relocated to St. Louis,  Missouri
but that  Executive  may be  required  to spend  substantial  amounts of time at
locations in and outside of St. Louis,  Missouri relating to the business of the
Corporation and its subsidiaries. It is understood that Executive shall continue
to reside in the vicinity of St. Louis,  Missouri and that the Corporation shall
maintain  an office  in St.  Louis,  Missouri,  which is where  Executive  shall
maintain his principal office until the Corporation relocates from New York City
to St. Louis,  Missouri.  The Corporation agrees to reimburse  Executive for his
reasonable  expenses,  including  hotel and travel  costs,  associated  with the
Corporation's business. In addition, until completion of such relocation,  it is
understood that Executive shall visit the Corporation's  executive office in New
York City on a regular  basis for meetings and to conduct  Corporation  business
that is more appropriately conducted from such executive office.

              3.  TERM.  Except  as  otherwise  provided  herein,  the  term  of
Executive's  employment hereunder shall commence on the date of the consummation
of the  merger of  Camelot  Pharmacal,  L.L.C.,  a  Missouri  limited  liability
company,  with and into a  subsidiary  of the Company (the  "Merger")  and shall
continue  to and  including  April 25,  2002.  Notwithstanding  anything  to the
contrary contained in the Agreement,  this Agreement shall terminate and have no
force and effect in the event that the  Merger is not  consummated  on or before
June 6, 1997.  Unless  terminated  earlier in accordance  with the terms hereof,
this  Agreement  shall  automatically  be  extended  for one or more  additional
consecutive  one year terms  unless  either  party  notifies  the other party in
writing at least six months  before the end of the then current term  (including
the initial term) of its or his desire to terminate this Agreement. The last day
of the term of this Agreement  pursuant to this Paragraph 3 (including any early
termination  pursuant  to  the  terms  hereof)  is  referred  to  herein  as the
"Termination Date."

              4. COMPENSATION.  (a) As compensation for his services  hereunder,
the  Corporation  shall pay to Executive (i) a base annual salary at the rate of
$160,000,  payable in equal  installments  in accordance with the normal payroll
practices of the Corporation but in no event less frequently than  semi-monthly,
and (ii)  such  incentive  compensation  and  bonuses,  if any,  as the Board of
Directors of the  Corporation in its absolute  discretion may determine to award
Executive  (it  being  understood  that  this  Agreement  shall  in no  event be
construed to require the payment to Executive of any incentive  compensation  or
bonuses),  it being  understood that Executive shall be entitled to receive such
incentive  compensation  and bonuses  determined  on a basis  comparable  to the
incentive compensation and/or bonuses awarded to other executive officers of the
Corporation.  All compensation paid to Executive shall be subject to withholding
and other employment taxes imposed by applicable law.

              (b)  During  the  period  of  Executive's   employment  hereunder,
Executive shall not be entitled to any additional


                                       2
<PAGE>
compensation   for  rendering   employment   services  to  subsidiaries  of  the
Corporation  or for  serving  in any  office  of the  Corporation  or any of its
subsidiaries to which he is elected or appointed.

              (c) In the event that  Executive  is elected to the  Corporation's
Board of  Directors,  Executive  will  receive  compensation  and  benefits as a
director  of the  Corporation  consistent  with the  compensation  and  benefits
received by the  Corporation's  other  directors  who are also  employees of the
Corporation.

              5. STOCK OPTIONS. (a) As additional  compensation for his services
hereunder,  the  Corporation  shall  grant to  Executive  an  option  under  the
Corporation's  1993 Stock Option Plan (the "Plan") to acquire a total of 400,000
shares of the Corporation's common stock at an exercise price per share equal to
the  closing  sale price of the  Corporation's  common  stock as reported by the
American Stock Exchange on the date hereof,  with the terms of such option to be
evidenced by (i) one option letter  agreement in the form annexed as Exhibit "A"
hereto  ("Option  Letter A-1") being  exercisable  for 100,000  shares of Common
Stock,  (ii) one option  letter  agreement in the form annexed as Exhibit  "A-2"
hereto  ("Option  Letter A-2") being  exercisable  for 150,000  shares of Common
Stock and (iii) one option  letter  agreement in the form annexed as Exhibit "B"
hereto ("Option Letter B") being  exercisable for 150,000 shares of Common Stock
(such option letters being referred to  collectively  herein as the "Plan Option
Letters").

              (b) The Company  represents and warrants that there are sufficient
shares of Common Stock currently available under the Company's 1993 Stock Option
Plan (the "1993 Plan") to cover the shares of Common Stock issuable to Executive
upon exercise of Option Letter A-1.

              (c) In the event that the Company's  stockholders fail at the next
annual  meeting  of  stockholders  of the  Corporation  to  approve  both (i) an
amendment  increasing the number of shares available for the issuance of options
under  the Plan to an  amount at least  sufficient  to cover  all the  shares of
Common Stock issuable upon exercise of Option Letter A-2 and Option Letter B and
(ii) appropriate amendments to the Plan specifically confirming the right of the
Corporation's  Board of  Directors,  in the issuance of stock  options under the
Plan,  to  determine  provisions  regarding  terms of the exercise of such stock
options  (including  without  limitation,  the period of exercisability of stock
options  under the Plan upon  termination  of  employment  for cause or  without
cause) and provisions  regarding forfeiture of stock options under the Plan upon
termination of employment,  the Company agrees, upon receipt of a written demand
from  Executive,  to promptly amend the Plan Option Letters to provide for three
non-qualified  options outside the Plan having  substantially the same terms and
provisions of the Plan Stock Options.

              (d) In the event that (i) the Corporation is required to amend the
Plan Option Letters pursuant to Paragraph 5(c) or (ii)



                                       3
<PAGE>
Executive's  employment by the  Corporation is terminated (x) by the Corporation
for any reason other than for Cause, (y) by Executive as a result of an Employer
Breach or (z) by the  Corporation  by reason of the  Executive's  disability  or
death  prior to the  expiration  of the  options  evidenced  by the Plan  Option
Letters and  Executive is required  after such event to pay any U.S.  federal or
state income and  withholding tax  (collectively,  "Income Taxes") on any income
recognized  by Executive  arising upon any exercise of options  evidenced by the
Plan  Option  Letters,   the  Corporation  agrees  to  reimburse  Executive  the
difference  between  (A) the amount of Income  Taxes  Executive  would have been
required to pay had the income  recognized  on such  exercise  been treated as a
long term capital  gain and (B) the amount of Income Taxes  payable by Executive
in respect of such exercise (the amount of such difference  being referred to as
the  "Tax  Difference"  in  respect  of such  exercise).  In  computing  the Tax
Difference,  the amount of taxes  payable by Executive  shall be  determined  by
assuming that the income recognized as a result of such exercise is taxed at the
highest  marginal  federal  and state  income tax rates  applicable  to ordinary
income. In addition,  the Corporation shall pay Executive an amount equal to the
Tax Difference arising in respect of such exercise multiplied by a fraction, the
numerator of which is 1 and the denominator of which is equal to 1 minus (i) the
highest marginal federal income tax rate (currently  39.6%) and (ii) the highest
marginal state income tax rate applicable to Executive,  in each case in respect
of ordinary income, in effect at the time of such exercise. Such amount shall be
paid by the  Corporation  within  ninety  (90)  days  after  any such  exercise.
Notwithstanding  anything to the  contrary in this  Agreement or the Plan Option
Letters, the Corporation shall have no obligation to pay Executive any amount in
excess of $250,000 in the  aggregate  in respect of its  obligations  under this
subparagraph.

              6.  ADDITIONAL  BENEFITS;  VACATION.  (a) In addition to such base
salary, Executive shall receive and be entitled to participate, to the extent he
is  eligible  under the terms and  conditions  thereof,  in any profit  sharing,
pension, retirement, hospitalization,  disability, medical service, insurance or
other employee benefit plan generally available to the executive officers of the
Corporation  that may be in  effect  from  time to time  during  the  period  of
Executive's  employment  hereunder.  The  Corporation  agrees to cover Executive
under  any  directors'  and  officers'   liability  policy   maintained  by  the
Corporation.

              (b)  Executive  shall be entitled to four (4) weeks' paid vacation
in respect of each 12-month period during the term of his employment  hereunder,
such vacation to be taken at times mutually agreeable to Executive and the Board
of Directors of the Corporation.

              (c) Executive  shall be entitled to recognize as holidays all days
recognized as such by the Corporation.

              7.  REIMBURSEMENT  OF EXPENSES.  The  Corporation  shall reimburse
Executive in accordance with applicable policies of the


                                       4
<PAGE>
Corporation for all expenses  reasonably  incurred by him in connection with the
performance of his duties  hereunder and the business of the  Corporation,  upon
the submission to the Corporation of appropriate receipts or vouchers.

              8. RESTRICTIVE COVENANT. (a) In consideration of the Corporation's
entering  into this  Agreement,  Executive  agrees that during the period of his
employment  hereunder  and, in the event of termination of this Agreement (i) by
the  Corporation  upon Executive  becoming  Disabled (as that term is defined in
Paragraph 13 hereof), (ii) by the Corporation for Cause (as that term is defined
in Paragraph 14 hereof) or (iii) by Executive otherwise than for Employer Breach
(as that term is defined in  Paragraph 15 hereof),  for a further  period of six
months thereafter,  he will not (x) directly or indirectly own, manage, operate,
join,  control,  participate  in,  invest in,  whether as an officer,  director,
employee, partner, investor or otherwise, any business entity that is engaged in
a  directly  competitive  business  (as  hereinafter  defined)  to  that  of the
Corporation or any of its subsidiaries within the United States of America,  (y)
for  himself  or on behalf  of any other  person,  partnership,  corporation  or
entity,  call on any customer of the Corporation or any of its  subsidiaries for
the purpose of soliciting  away,  diverting or taking away any customer from the
Corporation  or its  subsidiaries,  or (z) solicit any person then engaged as an
employee,  representative,  agent,  independent  contractor  or otherwise by the
Corporation  or any of its  subsidiaries,  to terminate his or her  relationship
with the Corporation or any of its subsidiaries. For purposes of this Agreement,
the term "directly  competitive  business"  shall mean any business that is then
involved in the research, development, manufacturing or commercialization in any
way of any  product,  compound,  device or method  that  acts or  functions  by,
through or on the same active,  binding or receptor  site,  mechanism of action,
signaling pathway or channel as any product,  compound, device or method that is
or becomes a part of the  Corporation's  business or the  business of any of its
subsidiaries  during  Executive's  employment by the  Corporation  or any of its
subsidiaries.  Nothing  contained in this Agreement  shall be deemed to prohibit
Executive  from investing his funds in securities of an issuer if the securities
of such issuer are listed for trading on a national  securities  exchange or are
traded in the over-the-counter market and Executive's holdings therein represent
less  than  10% of the  total  number  of  shares  or  principal  amount  of the
securities of such issuer outstanding.

              (b) Executive acknowledges that the provisions of this Paragraph 8
are  reasonable and necessary for the  protection of the  Corporation,  and that
each provision,  and the period or periods of time,  geographic  areas and types
and scope of  restrictions  on the  activities  specified  herein  are,  and are
intended to be, divisible.  In the event that any provision of this Paragraph 8,
including any sentence,  clause or part hereof,  shall be deemed contrary to law
or invalid or unenforceable in any respect by a court of competent jurisdiction,
the remaining provisions shall not be affected, but


                                       5
<PAGE>
shall, subject to the discretion of such court, remain in full force and effect.

              9. CONFIDENTIAL INFORMATION.

                   (a)  Executive  shall hold in a  fiduciary  capacity  for the
benefit of the Corporation and its subsidiaries  all  confidential  information,
knowledge and data relating to or concerned with its operations, sales, business
and affairs,  and he shall not, at any time during his employment  hereunder and
for two  years  thereafter,  use,  disclose  or  divulge  any such  information,
knowledge  or  data  to any  person,  firm  or  corporation  other  than  to the
Corporation and its subsidiaries or their respective  designees or except as may
otherwise be reasonably  required or desirable in  connection  with the business
and affairs of the Corporation and its subsidiaries.

                   (b)  Notwithstanding   anything  to  the  contrary  contained
herein,  Executive's  obligations under Paragraph 9(a) hereof shall not apply to
any information which:

              (i) becomes  rightfully known to Executive  subsequent or prior to
         his employment by the Corporation;

              (ii) is or becomes  available to the public other than as a result
         of wrongful disclosure by Executive;

              (iii) becomes available to Executive  subsequent to his employment
         by the Corporation on a nonconfidential  basis from a source other than
         the Corporation or its agents which source has a right to disclose such
         information; or

              (iv)  results  from  research and  development  and/or  commercial
         operations at any time by or on behalf of any person,  company or other
         entity with which or with whom Executive shall become  associated (in a
         manner  consistent with the terms of this Agreement)  subsequent to his
         employment by the  Corporation or its agents totally  independent  from
         any disclosure from the Corporation or its agents.

                   (c)  Notwithstanding   anything  to  the  contrary  contained
herein,  in the event that Executive  becomes legally  compelled to disclose any
confidential  information,  Executive will provide the  Corporation  with prompt
notice so that the Corporation may seek a protective order or other  appropriate
remedy. In the event that such protective order or other remedy is not obtained,
Executive  shall  furnish only such  confidential  information  which is legally
required to be disclosed.

              10. INTELLECTUAL  PROPERTY.  Any idea, invention,  design, written
material,  manual,  system,  procedure,  improvement,  development  or discovery
conceived,  developed, created or made by Executive alone or with others, during
the period of his  employment  hereunder  and  applicable to the business of the
Corporation  or  any  of  its   subsidiaries,   whether  or  not  patentable  or
registrable,


                                       6
<PAGE>
shall  become  the  sole  and  exclusive  property  of the  Corporation  or such
subsidiary.  Executive  shall  disclose the same promptly and  completely to the
Corporation and shall, during the period of his employment  hereunder and at any
time and from time to time  hereafter  at no cost to  Executive  (i) execute all
documents reasonably requested by the Corporation for vesting in the Corporation
or any of its  subsidiaries  the entire right,  title and interest in and to the
same,  (ii) execute all documents  reasonably  requested by the  Corporation for
filing and prosecuting such applications for patents, trademarks,  service marks
and/or  copyrights as the  Corporation,  in its sole  discretion,  may desire to
prosecute, and (iii) give the Corporation all assistance it reasonably requires,
including the giving of testimony in any suit, action or proceeding, in order to
obtain, maintain and protect the Corporation's right therein and thereto.

              11.  EQUITABLE  RELIEF.   The  parties  hereto   acknowledge  that
Executive's  services  are  unique  and  that,  in the  event of a  breach  or a
threatened  breach by Executive of any of his obligations  under Paragraphs 8, 9
or 10 this Agreement,  the Corporation shall not have an adequate remedy at law.
Accordingly,  in the event of any such breach or threatened breach by Executive,
the Corporation shall be entitled to such equitable and injunctive relief as may
be  available  to  restrain  Executive  and  any  business,  firm,  partnership,
individual,  corporation  or entity  participating  in such breach or threatened
breach from the  violation  of the  provisions  of  Paragraph 8, 9 or 10 hereof.
Nothing herein shall be construed as prohibiting the  Corporation  from pursuing
any other  remedies  available at law or in equity for such breach or threatened
breach,  including the recovery of damages and the immediate  termination of the
employment of Executive hereunder, if and to the extent permitted hereunder.

              12.   TERMINATION   OF  AGREEMENT;   TERMINATION   OF  EMPLOYMENT;
SEVERANCE;  SURVIVAL.  (a) This Agreement and Executive's  employment  hereunder
shall terminate upon the first to occur of the following: (i) Executive becoming
Disabled  (as that term is defined in  Paragraph  13 hereof);  (ii)  Executive's
death; (iii) termination of Executive's  employment by the Corporation for Cause
or pursuant to  subparagraph  (b) of this  Paragraph  12;  (iv)  termination  of
Executive's  employment  for  Employer  Breach and (v) the  termination  of this
Agreement  at the end of the  term of this  Agreement  on the  Termination  Date
pursuant to Paragraph 3.

                   (b)  Notwithstanding  anything to the  contrary  contained in
this Agreement, in the event of the termination of the Executive's employment by
the Corporation for any reason (other than for Cause), Executive shall be paid a
severance  payment equal to 75% of  Executive's  then current annual base salary
payable in nine equal monthly  installments,  with the first  installment  being
payable on the date  falling  two weeks after the date of such  termination  and
each  additional  installment  being paid every month after such date until such
severance is paid in full. In the event of such  termination of the  Executive's
employment by the Corporation (other than for Cause), the Corporation shall have
no


                                       7
<PAGE>
further  obligation  to the  Executive  under  this  Agreement  other  than  the
Corporation's  obligation  (i) to make such  severance  payment to the Executive
(ii) to pay Executive's COBRA premium payments for  hospitalization  and medical
insurance  coverage provided by the Corporation and to pay Executive's  premiums
on any death and/or disability insurance being maintained by the Corporation for
Executive  at the time of such  termination,  in each case until the  payment in
full of such severance payments

                   (c)  Paragraph  5(c)  of this  Agreement  shall  survive  the
termination of Executive's  employment  hereunder  until the earlier to occur of
Executive's exercise of all of the stock options granted pursuant to paragraph 5
and the  expiration  of all such  stock  options  pursuant  to the Stock  Option
Letters.  Paragraphs 7, 8, 9, 10, 11 and 26 of this Agreement  shall survive the
termination  of  Executive's  employment  hereunder,   except  in  the  case  of
termination pursuant to Paragraph 15.

              13.  DISABILITY.  In  the  event  that  during  the  term  of  his
employment by the  Corporation  Executive shall become Disabled (as that term is
hereinafter  defined)  he shall  continue to receive the full amount of the base
salary to which he was theretofore  entitled for a period of six months after he
shall be deemed to have become Disabled (the "First Disability Payment Period").
If the First Disability  Payment Period shall end prior to the Termination Date,
Executive thereafter shall be entitled to receive salary at an annual rate equal
to 80% of his then  current  base  salary  for a  further  period  ending on the
earlier of (i) six months  thereafter or (ii) the Termination  Date (the "Second
Disability  Payment  Period").  Upon the  expiration  of the  Second  Disability
Payment Period,  Executive shall not be entitled to receive any further payments
on account of his base salary until he shall cease to be Disabled and shall have
resumed his duties  hereunder and provided that the  Corporation  shall not have
theretofore  terminated this Agreement as hereinafter provided.  The Corporation
may terminate  Executive's  employment  hereunder at any time after Executive is
Disabled, upon at least 10 days' prior written notice;  PROVIDED,  HOWEVER, that
such  termination  shall not relieve the Corporation from its obligation to make
the payments to Executive described above in this Paragraph 13. For the purposes
of this Agreement, Executive shall be deemed to have become Disabled when (x) by
reason of physical or mental  incapacity,  Executive  is not able to perform his
duties  hereunder  for a period  of 90  consecutive  days or for 120 days in any
consecutive  180-day  period or (y) when  Executive's  physician  or a physician
designated by the Corporation  shall have determined that Executive shall not be
able,  by reason of  physical  or mental  incapacity,  to perform a  substantial
portion of his duties  hereunder.  In the event that Executive shall dispute any
determination of his disability pursuant to clauses (x) or (y) above, the matter
shall be resolved by the determination of three physicians qualified to practice
medicine  in the United  States of  America,  one to be  selected by each of the
Corporation  and  Executive  and the  third  to be  selected  by the  designated
physicians.  If Executive  shall receive  benefits under any  disability  policy
maintained by the Corporation, the Corporation


                                       8
<PAGE>
shall be entitled to deduct the amount  equal to the  benefits so received  from
base salary that it  otherwise  would have been  required to pay to Executive as
provided above.

              14.  TERMINATION  FOR CAUSE.  The Corporation may at any time upon
written notice to Executive  terminate  Executive's  employment  for Cause.  For
purposes of this  Agreement,  the  following  shall  constitute  Cause:  (i) the
willful  and  repeated  failure of  Executive  to perform  any  material  duties
hereunder or gross  negligence of Executive in the  performance  of such duties,
and if such failure or gross negligence is susceptible to cure by Executive, the
failure to effect such cure within twenty (20) days after written notice of such
failure or gross  negligence  is given to  Executive;  (ii) except as  permitted
hereunder,  unexplained,  willful and regular  absences  of  Executive  from the
Corporation;  (iii) excessive use of alcohol or illegal drugs,  interfering with
the performance of Executives duties  hereunder;  (iv) indictment for a crime of
theft, embezzlement,  fraud, misappropriation of funds, other acts of dishonesty
or the violation of any law or ethical rule relating to Executive's  employment;
(v) indicted for any other felony or other crime  involving  moral  turpitude by
Executive;  or  (vi)  the  breach  by  Executive  of any of  the  provisions  of
paragraphs  8, 9 or 10 and if such breach is  susceptible  of cure by Executive,
the failure to effect such cure within twenty (20) days after written  notice of
such breach is given to  Executive.  For purposes of this  Agreement,  an action
shall  be  considered  "willful"  if  it is  done  intentionally,  purposely  or
knowingly,   distinguished  from  an  act  done  carelessly,   thoughtlessly  or
inadvertently.  In any such  event,  Executive  shall be entitled to receive his

provision of this  Agreement,  and if such breach is  susceptible  of cure,  the

entire  agreement of the parties  hereto,  and any prior  agreement  between the
Corporation  and  Executive  is  hereby  superseded  and  terminated   effective
immediately  and shall be without  further  force or  effect.  No  amendment  or
modification himself shall be valid or binding unless made in writing and signed

Executive, his heirs, executors and administrators and upon the Corporation, its
successors and assigns.

              20.  WAIVERS.  No course of  dealing  nor any delay on the part of
either party in exercising any rights hereunder shall operate as a waiver of any
such  rights.  No waiver of any  default  or breach of this  Agreement  shall be
deemed a continuing waiver or a waiver of any other breach or default.

              21.  GOVERNING  LAW.  This  Agreement  shall  be  governed  by and

Agreement  shall be held or  declared to be void,  invalid or  illegal,  for any
reason,  by any  court  of  competent  jurisdiction,  such  provision  shall  be
ineffective  but shall not in any way  invalidate  or affect  any other  clause,
paragraph, section or part of this Agreement.

              23.  FURTHER  ASSURANCES.  Each of the parties  shall execute such
documents  and take such other  actions as may be  reasonably  requested  by the

accordance with its terms.

              24. HEADINGS.  The headings  contained in this Agreement have been

to or at the time of  execution  of this  Agreement  with  respect  to the terms
contemplated  hereby,  except as required by applicable  law,  without the prior
approval of the other party, which approval will not be unreasonably withheld.

              26.  ARBITRATION.  Any disputes arising under this Agreement shall
be  submitted  to and  determined  by  arbitration  in New York City,  New York;
PROVIDED, HOWEVER, that such arbitration shall be held in St. Louis, Missouri in
the event that the Company's  principal executive offices is located at the time
