                                    Placement A Units of Belmac Corporation
                                    ---------------------------------------
Gentlemen:

         This will acknowledge that the undersigned hereby agrees to irrevocably
purchase from Belmac  Corporation  (the  "Company" or  "Belmac"),  a corporation
organized under the laws of the State of Florida in February 1974, ___________ A
Unit(s)  (collectively  the "A Units") at a price of $60,000  per A Unit.  The A
Unit(s) to be purchased by the undersigned is (are) part of a private  placement
of securities (the "Private Placement") by the Company of up to 17 A Units which
is being effected on an best efforts basis by the Company. Accordingly, there is
no  minimum  number  of A Units  that  must be sold  in  order  for the  Private
Placement to become effective.  The Company reserves the right to sell fractions
of an A Unit.

         If all of the A Units are sold,  the Company  will receive an aggregate
of  $1,020,000  less the expenses of this  Private  Placement  which  management
estimates will  approximate  $130,000,  including the fee payable to Coleman and
Company Securities,  Inc. ("Coleman")  described below. Coleman, a member of the
New York Stock  Exchange,  is acting as the  placement  agent for the Company in
placing this Private  Placement.  Coleman will receive a fee equal to 10% of the
of the aggregate  purchase price of the A Units sold. The Private Placement will
terminate on the sooner to occur of the sale of all of the A Units or October 6,
1995,  unless  extended for an additional  15 days by the mutual  consent of the
Company and Coleman.  The undersigned  understands that the information provided
to him with  respect  to the  Company  has not been  independently  verified  by
Coleman.  Accordingly,   there  is  no  representation  by  Coleman  as  to  the
completeness or accuracy of such information.

         Payment  for the A Units  shall be made by check,  payable to  Citibank
N.A. - Belmac  Corporation  Escrow Account,  and delivered to Coleman,  together
with an executed  copy of this  




                                                                   Initial ____

Subscription  Agreement  and  Investment  Letter.  Payment  may be  made by wire
transfer pursuant to instructions available on request from Coleman.

         Each A Unit  consists  of a note  (collectively  the "A  Notes") in the
principal amount of $60,000,  bearing interest at the annual rate of 12% payable
quarterly,  and 7,500 shares (the "A Unit Shares") of the Company's common stock
(the  "Common  Stock").  The A  Notes  and A Unit  Shares  will  be  immediately
detachable.

         The  principal  of each A Note is due and  payable on the  closing of a
Public Offering (as defined  below).  In the event that a Public Offering is not
completed by September 30, 1996,  the principal of each A Note will be converted
automatically  into  Common  Stock at a price  per  share  equal to the  average
closing price for the Common Stock quoted on the American Stock Exchange for the
five trading days immediately preceding September 30, 1996. The Company will pay
all accrued but unpaid interest to the A Note holder on the conversion date.

         The A Notes will not be secured and will be subordinated to all "Senior
Debt" as that  term is  defined  therein.  The A Notes  will  not be  personally
guaranteed and there will be no sinking fund,  trustee or indenture with respect
thereto.

         The undersigned  understands that if a Public Offering is not completed
by September  30, 1996, he will be required to convert the principal of his Note
into Common Stock at a price per share based on the formula described above. The
conversion  price is subject to adjustment  in accordance  with the terms of the
anti-dilution provisions set forth in the Notes.

         The   undersigned   understands   that  the  Company  and  Coleman  are
contemplating  a public  offering  (the  "Public  Offering")  subsequent  to the
completion  of  this  Private   Placement.   Any  registration   statement  (the
"Registration   Statement")  to  be  filed  with  the  Securities  and  Exchange
Commission (the  "Commission")  will include  provisions for the registration of
the A Unit  Shares and the shares of Common  Stock  underlying  the Notes in the
event  that  the A Notes  are  converted  as  provided  above  (the  "Underlying
Shares").  The undersigned  acknowledges that no assurance can be given that the
Registration  Statement,  if filed, will be declared effective by the Commission
or, if it is,  that the Public  Offering  will ever be  successfully  completed.
Accordingly, he warrants and represents to the Company that he is purchasing the
A Units without relying on the occurrence of the Public Offering.

         If the  Registration  Statement  is not  filed,  or if filed and is not
declared  effective,  the  holders  of a majority  of the A Unit  shares and the
Underlying Shares will have the right, on one occasion only through December 31,
1997,  to  demand  that  the  Company   register  the  A  Unit  Shares  and  the
                                                                      

                                                                   Initial ____

Underlying  Shares  with the  Commission  and use its best  efforts to have such
registration statement declared effective.

         The  undersigned is aware that the Company will use the net proceeds of
this Private Placement,  which management estimates will approximate $890,000 if
all of the A Units are sold,  primarily  for  payment of general  administrative
expenses  and working  capital.  To the extent that less than all of the A Units
are sold,  less money will be  available  for these  purposes.  The  undersigned
understands  and  acknowledges  that the  Company  will be  required  to  obtain
additional financing, such as that contemplated by the Public Offering, in order
to continue to operate its business over the next 12 months.

         The undersigned is also aware that the Company has recently completed a
private  sale of 12 Units (the  "Prior  Units") for a gross  aggregate  price of
$720,000.  The Prior Units are  identical  to the A Units  except that the Prior
Unit notes are  convertible  at the option of the  holders  thereof  into Common
Stock at a price of $3.00 per share and each Prior Unit holder  received  10,000
shares  of Common  Stock per unit  instead  of the 7,500  shares  per unit to be
received by an A Unit Purchaser.

         The  undersigned  acknowledges  that  the  A Units and the underlying A
Notes and A Unit Shares (the "Underlying Securities") he is purchasing,  as well
as any  Underlying  Shares into which the Notes may be converted,  have not been
registered under the Act or qualified under applicable state securities laws and
that the transferability thereof is restricted by the registration provisions of
the  Act as  well as  such  state  laws.  Based  upon  the  representations  and
agreements being made by him herein,  the A Units and Underlying  Securities are
being sold to him pursuant to an exemption  from such  registration  provided by
Section 4(2) of the Act and Rule 506 promulgated thereunder and applicable state
securities law qualification  exemptions.  The undersigned further  acknowledges
that the basis for the exemption may not be available,  if notwithstanding  such
representations,  he intends merely  acquiring  these  securities for a fixed or
determinable  period in the  future,  or for a market  rise,  or for sale if the
market does not rise. The  undersigned  represents and warrants that he does not
have  any  such  intention.   The  undersigned  agrees  that  the  documentation
representing  the  Underlying  Securities  to be received by him, as well as the
certificates  representing  any  Underlying  Shares  into which the Notes may be
converted,  will bear a legend  indicating that transfer of these  securities is
restricted  by  reason of the fact  that  they  have not been so  registered  or
qualified.

         The  undersigned  represents  that  he is  acquiring  the A  Units  and
Underlying  Securities  solely  for his own  account as  principal  and not as a
nominee or agent, for investment  purposes only and not with a view to resale or
other distribution or fractionalization thereof, nor with the intention of sell-
ing,  transferring  or otherwise disposing of all or any part of such securities
for any  particular   event  or   circumstance,   except   selling, transferring
or  disposing  of them  upon  full  compliance  with  all  applicable provisions
of  the  Act,  the  Securities  Exchange  Act  of 1934 (the "Exchange Act"), the



                                                                   Initial ____

Rules  and  Regulations  promulgated  by  the  Commission  thereunder,  and  any
applicable state securities laws. The undersigned further understands and agrees
that the securities may be sold only if they are  subsequently  registered under
the Act and qualified  under any  applicable  state  securities  laws or, in the
opinion of the  Company's  counsel,  an  exemption  from such  registration  and
qualification  is available,  and that any routine  sales of securities  made in
reliance upon Rule 144  promulgated  by the  Commission  can be made only in the
amounts set forth in and pursuant to the other terms and  conditions,  including
applicable  holding periods,  of that Rule. He also understands  that, except as
otherwise set forth herein, the Company is under no obligation to register the A
Units or  UnderlyingSecurities  on his behalf or to assist him in complying with
any exemption from registration under the Act.

         The undersigned  represents and warrants that he has received a copy of
the A Note,  the Company's  Form 10-K for the year ended  December 31, 1994, the
Company's Form 10Qs for the quarters ended March 31, 1995 and June 30, 1995, the
Company's Proxy Statement for the Company's June 9, 1995 Annual Meeting, and the
Company's 1994 Annual Report,  (collectively  the  "Information  Documents") and
that he has read and understood these documents.

         The  undersigned  also represents and warrants that he (i) has reviewed
such other  documents as he deems necessary in order for him to make an informed
investment  decision;  and (ii) is fully aware of the Company's current business
prospects and weak financial condition as set forth below and in the Information
Documents.  Except  as  may be  provided  in  this  Subscription  Agreement  and
Investment  Letter  and  in the  Information  Documents,  he  warrants  that  no
representations,  statements or  inducements  were made to him to purchase the A
Units.

         Based on the foregoing,  the undersigned  acknowledges that he is aware
that Belmac is an international  pharmaceutical  and healthcare company based in
Tampa, Florida,  engaged primarily in the research,  development,  marketing and
distribution of pharmaceutical and healthcare products. The Company has chemical
and  pharmaceutical  operations  in  France  and  Spain as a result  of its 1991
acquisition  of Chimos S.A.  and the  establishment  of a French  pharmaceutical
subsidiary,  Laboratories Belmac S.A. (these two French entities have since been
merged into one entity named and  referred to herein as  "Chimos")  and the 1992
acquisition  of Rimafar  S.A.  (subsequently  renamed and  referred to herein as
"Laboratorios Belmac"), respectively. The Company's operations in France consist
of  the  brokerage  of  chemicals  and  the  marketing  of  the  drug  Ceredase,
manufactured by the Boston, Massachusetts-based Genzyne Corporation. Ceredase is
used in the  treatment  of Gaucher's  Disease.  The Company uses its facility in
Spain to  manufacture,  package and distribute  both its own and other companies
pharmaceutical  products.  The  Company  has  expanded  its  healthcare  product
distribution  business  into  the  United  States  through  the establishment of
Belmac   Healthcare   Corporation,  Belmac   Hygiene,  Inc.  and  Belmac  Health
Corp.  Belmac   Healthcare   Corporation   markets   disposable   linens

                                                              

                                                                   Initial ____

to emergency health services.  Research and development activities are conducted
both in the  United  States and  Europe.  The  undersigned  is also aware of the
following:

         1. HISTORY OF OPERATING  LOSSES;  ACCUMULATED  DEFICIT;  UNCERTAINTY OF
FUTURE  FINANCIAL  RESULTS.  As of June 30,  1995,  the Company had a cumulative
deficit of  approximately  $62,899,000.  The  Company has  realized  significant
losses in the past and could have quarterly and annual losses in the future. The
Company  has only  recently  begun to generate  significant  revenue and has not
generated  any  profits  from  operations.  The Company  experiences  quarter to
quarter  fluctuations in revenues and profits and/or losses, some of which could
be significant.  Consequently, the Company may continue to operate at a loss for
the foreseeable future and there can be no assurance that the Company's business
will ever operate on a profitable basis.

         2. NO ASSURANCE OF SUCCESSFUL  AND TIMELY  DEVELOPMENT OF NEW PRODUCTS.
Although the Company was founded in 1974, it his only recently begun to generate
meaningful revenue from product-related  sales. The Company has made significant
progress  toward  commercialization  of  specific  products  and  has  commenced
commercialization  of others. The Company is now generating  revenues from sales
of products of its subsidiaries  Chimos and Laboratorios  Belmac which, as noted
above,  were  acquired  by  the  Company  in  August  1991  and  February  1992,
respectively. Substantial amounts of time and financial and other resources will
be required to complete the  development  and chemical  testing of the Company's
products  currently  under  development  including  the  tablet  formulation  of
Biolid(R),  the Company's macrolide  antibiotic.  Although over the last several
months the Company has continued its existing  limited  research and development
program, due to its limited cash resources, it has suspended additional research
and  development  activities  during such period  pending  receipt of additional
financing.  There is no  assurance  that the  Company  will  receive  additional
funding  necessary to commence full research and development  activities or that
it  will  otherwise   succeed  in  developing   any  additional   products  with
commercially viable applications.

         Although  the Company  has a number of  products  in various  stages of
development,  including pre-clinical testing and clinical trials, it has not yet
substantially marketed any of these products other than Biolid(R) in France, the
marketing  of  which  has  since  been   suspended   (see  "Risks   Inherent  in
Pharmaceutical  Development;  Dependence on Regulatory  Approvals" below). There
can be no  assurance  that  the  Company  will be able to  develop  large  scale
production of any particular product for clinical trials or eventual  commercial
production.  The  marketing  of  certain  of the  Company's  products  could  be
adversely  affected by delays in developing  large-scale  production  processes,
developing or acquiring  production  facilities or obtaining regulatory approval
for such processes or facilities.

         3. ADDITIONAL FINANCING REQUIREMENTS.  Belmac's pharmaceutical products
being  developed  and which may be  developed  will  require the  investment  of
substantial additional time as 


                                                                   Initial ____


                               Page 5 of 16 Pages




Subscription Agreement and Investment Letter for

well  as  financial  and  other  resources  in  order  to  become   commercially
successful.  Following  the  development  period,  the  Company's  products will
generally  be  required  to undergo  lengthy  governmental  approval  processes,
including  extensive  clinical  testing,  followed  by market  development.  The
Company's  operating  revenues and cash resources may not be sufficient over the
next several years for the commercialization by itself of all products currently
in development.  Consequently,  the Company may require additional  licensees or
partners  and/or  additional  financing.   The  Company  believes  that  careful
management  of its research and  development  activities,  together with the net
proceeds  from this  Offering and the  proposed  Public  Offering,  will provide
sufficient liquidity to enable it to conduct its existing operations through the
end of 1996. Belmac further believes,  however, that by controlling and managing
its expenses,  the funds on hand together with the proceeds of this Offering and
the proposed Public Offering, the sale or license of certain of its assets which
are no longer a part of its strategic  plan, or the entering into joint ventures
with other entities will be sufficient for it to continue its operations for the
foreseeable  future.  There can be no assurance,  however,  that the Company can
conclude such commercial  arrangements or obtain additional  capital when needed
on acceptable terms, if at all.

         4. INDEPENDENT  AUDITOR'S  REPORT.  Because Belmac continues to sustain
losses the opinion of its  independent  auditors  with respect to its  financial
statements,  will include an explanatory  paragraph as to the uncertainty of the
Company's  ability to continue as a going concern without  additional funds. The
ability  of  Belmac  to  continue  as a going  concern  is  dependent  upon  the
successful  completion of this Private  Placement and the Public Offering and/or
receiving sufficient revenue from its operations.

         5.  RISKS  INHERENT  IN  PHARMACEUTICAL   DEVELOPMENT;   DEPENDENCE  ON
REGULATORY  APPROVALS.  The process of creating,  scaling-up,  manufacturing and
marketing  any new human  pharmaceutical  is inherently  risky.  There can be no
assurance that any drug under development will be safe and effective.  Moreover,
pharmaceutical  products  are  subject  to  significant  regulation.  Any  human
pharmaceutical  product  developed by the Company  would require the approval of
the Food and Drug  Administration  ("FDA")  in the  United  States  and  similar
agencies in other countries.  The process of obtaining these approvals is costly
and  time-consuming,  and there can be no assurance  that such approvals will be
granted.  In general,  only a small  percentage of new  pharmaceutical  products
achieve  commercial  success.  Such  governmental   regulation  may  prevent  or
substantially delay the marketing of the Company's products and may cause Belmac
to undertake costly  procedures with respect to its research and development and
clinical testing  operations  which may furnish a competitive  advantage to more
substantially capitalized companies which compete with the Company. In addition,
the Company is  required,  in  connection  with a number of its  activities,  to
comply with  local,  state and federal  regulations.  Non-compliance  with these
regulations  could have a material  adverse effect on the Company and/or prevent
the commercialization of the Company's products.



                                                                   Initial ____

         In 1994 the French regulatory authority requested further documentation
regarding the chemical process/characteristics of Belmac's sachet formulation of
Biolid(R). Until this additional information has been reviewed and approved, the
regulatory  authority has requested  that marketing of the product be suspended.
Although the Company regards this  administrative  action as unwarranted in view
of the  existing  safety  and  efficacy  experience  to date in  France,  it has
determined  not  to  challenge  the  administrative  decision  in  light  of its
previously  announced  decision to develop the tablet  formulation of Biolid(R).
The Company  believes  that the actions of the French  regulatory  agency should
have no bearing on the  development  of and  approval  process  for a  Biolid(R)
tablet  formulation  elsewhere,  of which  there  can be no  assurance.  Once it
receives  regulatory  clearance,  the  Company  intends  to again  evaluate  its
alternatives  regarding the sachet  formulation,  including the  possibility  of
seeking a licensee or buyer for the product's rights in France.

         6. DEPENDENCY AN OTHERS.  The  Company  relies  on  outside  sources to
supply certain raw materials such as erythromycin  ethyl succinate.  The Company
relies on outside  contractors for  manufacturing  of its products in France and
expects to rely at least  partially  on contract  manufacturing  in Spain and in
other  countries.  The  Company  may also  need to  utilize  third  parties  for
distribution of its products.

         7. UNCERTAINTY OF  PHARMACEUTICAL  PRICING,  PROFITABILITY  AND RELATED
MATTERS.  The levels of revenues and profitability of  pharmaceutical  companies
may be affected by the continuing efforts of governmental and third party payors
to  contain  or reduce  the costs of health  care  through  various  means.  For
example,  in certain foreign markets  pricing or  profitability  of prescription
pharmaceuticals  is subject to  government  control.  In the United States there
have been,  and the Company  expects that there will continue to be, a number of
federal and state  proposals  to implement  similar  government  control.  While
Belmac cannot predict whether any such legislative or regulatory  proposals will
be adopted,  the adoption of such proposals could have a material adverse effect
on the Company's business,  financial condition and profitability.  In addition,
in both the United States and elsewhere,  sales of prescription  pharmaceuticals
are dependent in part on the  availability of reimbursement to the consumer from
third party payors,  such as government and private insurance plans. Third party
payors are increasingly  challenging the prices charged for medical products and
services.  If the  Company  succeeds  in  bringing  one or more  products to the
market,  there can be no assurance that these  products will be considered  cost
effective  and that  reimbursement  to the consumer will be available or will be
sufficient to allow the Company to sell its products on a competitive basis.

         8.  ACCOUNTS  PAYABLE  DELINQUENCIES.   A  significant  number  of  the
Company's accounts payable have been or are delinquent. As of June 30, 1995, the
Company  had  total  accounts  payable  in the  amount of  $5,524,000,  of which
approximately 5% or $300,000 was overdue.  The Company will utilize a portion of
the proceeds of this Offering to make some of these payments.


                                                                   Initial ____

Subscription Agreement and Investment Letter for
investment in A Units of Belmac Corporation dated _________ __, ____.



         9.  UNPREDICTABILITY  OF  PATENT  PROTECTION;  PROPRIETARY  TECHNOLOGY.
Belmac has filed numerous patent  applications  and has been granted a number of
patents.  However,  there can be no assurance that its pending applications will
be issued as patents  or that any of its issued  patents  will  afford  adequate
protection to the Company or its  licensees.  Other private and public  entities
have also filed applications for, or have been issued,  patents and are expected
to obtain  patents  and other  proprietary  rights  to  technology  which may be
harmful to the  commercialization of the Company's products.  The ultimate scope
and  validity  of  patents  which  are now owned by or may be  granted  to third
parties in the  future,  the extent to which the Company may wish or be required
to acquire  rights  under such  patents,  and the cost or  availability  of such
rights cannot be  determined  by the Company at this time.  In addition,  Belmac
also  relies  on  unpatented  proprietary  technology  in  the  development  and
commercialization  of its  products.  There is no assurance  that others may not
independently  develop the same or similar  technology  or obtain  access to the
Company's proprietary technology.

         Belmac also relies upon trade secrets,  unpatented proprietary know-how
and continuing  technological  innovations to develop its competitive  position.
All of  the  Company's  employees  with  access  to  the  Company's  proprietary
information  have entered  into  confidentiality  agreements  and have agreed to
assign  to the Company any inventions relating to the Company's business made by
them while in the  Company's  employ.  However,  there can be no assurance  that
others may not  acquire  of  independently  develop  similar  technology  or, if
patents in all major  countries  are not issued  with  respect to the  Company's
products,  that the Company  will be able to maintain  information  pertinent to
such research as proprietary technology or trade secrets.

         10. TECHNOLOGICAL CHANGE AND COMPETITION.  The pharmaceutical  industry
has undergone rapid and significant  technological  change.  The Company expects
the technology to continue to develop  rapidly,  and the Company's  success will
depend  significantly on its ability to maintain a competitive  position.  Rapid
technological  development  may  result  in  actual  and  proposed  products  or
processes becoming obsolete before the Company recoups a significant  portion of
related research and development and commercialization expenses.

         Belmac competes with other pharmaceutical companies, biotechnology firm
and chemical companies which have substantially greater financial, marketing and
human  resources  than  those  of  the  Company   (including,   in  some  cases,
substantially  greater experience in clinical testing,  production and marketing
of  pharmaceutical  products).  The Company also experiences  competition in the
development of its products and processes from individual scientists, hospitals,
universities and other research  institutions  and, in some instances,  competes
with others in acquiring technology from these sources.

         11.  ATTRACTION  AND RETENTION OF KEY PERSONNEL.  The Company  believes
that   it   has   been   successful  in   attracting   skilled  and  experienced
management  and  scientific  personnel.  There can be

                                                                   Initial ____

no assurance, however, that Belmac will continue to attract and retain personnel
of high  caliber.  Since  January 1994 two  individuals  who have each served as
chief executive officer and a member of its board of directors and an additional
member of its board have resigned from their respective  positions.  The loss of
key  management  or  scientific  personnel  could have an adverse  impact on the
Company.  The Company has not entered into non  competition  agreements with its
key employees and such  employees  would  therefore be able to leave and compete
with the Company.

         12. RISK OF PRODUCT  LIABILITY.  The Company faces an inherent business
risk of  exposure to product  liability  claims in the event that the use of its
technology  or  prospective  products  is  alleged to have  resulted  in adverse
effects.  While it has taken,  and will  continue to take,  what it believes are
appropriate  precautions,   there  can  be  no  assurance  that  it  will  avoid
significant liability exposure. Belmac maintains product liability in the amount
of $5  million.  However,  there is no  assurance  that  this  coverage  will be
adequate  in terms and scope to  protect  the  Company in the event of a product
liability claim. In connection with the Company's  clinical testing  activities,
the Company may, in the ordinary  course of business,  be subject to substantial
claims by, and liability to, subjects who participate in its studies.

         13. VOLATILITY OF SHARE PRICE. The market price of the Company's shares
since  Belmac's  initial  public  offering in February  1988 has been  volatile.
Factors such as  announcements  of  technological  innovations or new commercial
products by the  Company or its  competitors,  the results of clinical  testing,
patent  or  proprietary  rights,  developments  or  other  matters  may  have  a
significant impact on the market price of the Common Stock.

         14.  POSSIBLE  DELISTING OF COMMON STOCK FROM AMERICAN STOCK  EXCHANGE.
The Company  currently  does not satisfy some of the American  Stock  Exchange's
financial  guidelines for continued listing of its Common Stock. While there can
be no assurance  that listing on the American  Stock Exchange will be continued,
management of the Company  believes that the  Company's  business  prospects are
improving and that it will be able to maintain continued listing.  If the Common
Stock were  delisted,  an investor could find it more difficult to dispose of or
to obtain accurate quotations as to the price of the Common Stock.

         15. LACK OF DIVIDENDS;  INABILITY TO FUND DIVIDEND PAYMENTS. Belmac has
not paid  dividends on its Common Stock since its  inception and does not intend
to pay any dividends on its Common Stock in the foreseeable  future. The holders
of the  Company's  outstanding  Series A Preferred  Stock have been  entitled to
receive cumulative dividends, payable annually on October 15, since 1992, out of
funds legally available  therefor at the rate of $2.25 per year on each share of
Series A  Preferred  Stock.  The Company  has not paid  dividends  to holders of
Series A Preferred  Stock due on October 15, 1994.  These  arrearages  currently
have the effect of limiting  the payment of cash 

                                                                   Initial ____

investment in A Units of Belmac Corporation dated _________ __, ____.


dividends to holders of Common Stock.  There can be no assurance  that cash flow
from Belmac's future operations will be sufficient to meet these obligations.

         16.  BROAD DISCRETION IN APPLICATION OF PROCEEDS.  Approximately all of
the  estimated  net proceeds  from this  Offering has been  allocated to working
capital.  Accordingly, the Company's management will have broad discretion as to
the application of such funds.

         17.  CERTAIN  FLORIDA  LEGISLATION.  The State of Florida  has  enacted
legislation that may deter or frustrate takeovers of Florida  corporations.  The
Florida  Control Share Act generally  provides that shares acquired in excess of
certain  specified  thresholds  will not possess any voting  rights  unless such
voting rights are approved by a majority vote of a  corporation's  disinterested
shareholders.   The  Florida  Affiliated  Transactions  Act  generally  requires
supermajority  approval  by  disinterested  shareholders  of  certain  specified
transactions  between a public  corporation  and holders of more than 10% of the
outstanding voting shares of the corporation (or their affiliates).  Florida law
also  authorizes  the  Company to indemnify  the Company's  directors,  officers
employees and agents.

         18. UNCERTAINTY OF ORPHAN DRUG DESIGNATION.  Under the Orphan Drug Act,
the FDA may  designate  a product or  products  as having  Orphan Drug status to
treat a rare disease or condition,  which is a disease or condition that affects
populations of less than 200,000 individuals in the United States or, if victims
of a disease number more than 200,000,  the sponsor establishes that it does not
realistically  anticipate  its product  sales will be  sufficient to recover its
costs.  If a product is designated an Orphan Drug,  then the sponsor is entitled
to recover its costs and receive certain incentives to undertake the development
and marketing of the product,  including  limited tax credits and  high-priority
FDA review of a New Drug  Application  ("NDA").  In  addition,  the sponsor that
obtains the first  marketing  approval for a designated  Orphan Drug for a given
indication is eligible to receive  marketing  exclusivity  for a period of seven
years. There may be multiple designations of Orphan Drug status for a given drug
and for different  indications.  However, only the sponsor of the first approved
NDA for a given drug for its use in  treating a given rare  disease  may receive
marketing exclusivity. While it may be advantageous to obtain Orphan Drug status
for  eligible  products,  there can be no  assurance  that the precise  scope of
protection that is currently afforded by Orphan Drug status will be available in
the future or that the current level of exclusivity  and tax credits will remain
in effect.  Currently,  Congress is considering legislation that would amend the
Orphan  Drug Act and may limit the scope of  marketing  exclusivity  granted  to
Orphan Drug products.  Moreover, the Orphan Drug Act tax credits expired on June
30, 1992. Although  legislation has been introduced to renew these tax benefits,
there can be no assurance that they will be renewed.

         The undersigned  understands that,  because of the Company's  financial
condition  and acute working  capital  problem as well as the other risk factors
referred to herein and in the  Information  Documents,  he could lose his entire
investment.
