                  OPINION  OF  COUNSEL TO  MAKER, AN EXEMPTION 
                  THEREFROM IS AVAILABLE.


FOR VALUE RECEIVED, the undersigned,  BELMAC CORPORATION,  a Florida corporation
with offices at One Urban Centre, Suite 550, 4830 West Kennedy Boulevard, Tampa,
Florida 33609-2517 ("Maker"),  promises to pay to _____________________  with an
address  at  ______________________________  ("Payee"),  on the  closing  of the
Public  Offering (as defined in Section 3 below)  except as  otherwise  provided
herein  (the  "Maturity   Date"),   the  principal   amount  of  Sixty  Thousand
($60,000.00)  Dollars  in lawful  money of the  United  States of  America  (the
"Principal") together with all accrued interest.

This Note bears simple  interest (the  "Interest")  at the annual rate of twelve
percent (12%), which is payable,  in arrears,  on the Interest Payment Dates (as
defined  in  Section 1 below),  until the  Principal  and all  accrued  Interest
thereon shall be paid in full.  The Note is  subordinated  to certain of Maker's
indebtedness  and is convertible into Maker's common stock (the "Common Stock"),
all as set forth below.

This Note is one of a series of notes (the "Notes"), all with the same terms and
conditions  as those  set forth  herein,  which may be issued by Maker up to the
aggregate  principal  amount of Seven  Hundred  and Twenty  Thousand  ($720,000)
Dollars.  Each  Note is  included  in a unit  (the  "Unit")  which is part of an
offering of 12 Units (the "Offering") being conducted by Maker on a best efforts
basis. The Offering will terminate on the sooner of the sale of all of the Units
or September 30, 1995. Each Unit consists of one Note in the principal amount of
Sixty Thousand ($60,000) Dollars and 10,000 shares (the "Unit Shares") of Common
Stock.  Accordingly,  in connection with the acquisition of this Note, Payee has
also received 10,000 Unit Shares.

1.       INTEREST.

Maker  will pay  Interest  on the first  day of each  January,  April,  July and
October  commencing on January 1, 1996 (the "Interest Payment Dates").  Interest
on the Note will accrue from the most  recent  date to which  interest  has been
paid or, if no  interest  has been paid,  from the date of delivery of the Note.
Interest  will be  computed  on the  basis of a  360-day  year of  twelve 30 day
months.

2.       METHOD OF PAYMENT.

Maker will pay  Principal and Interest in money of the United States that at the
time of payment is legal  tender for the  payment of public and  private  debts.
However,  Maker may pay  Principal  and  Interest  by its check  payable in such
money.  It may mail an Interest check to Payee's  address as it first appears on
this Note or such other  address as Payee  shall give by notice to Maker.  Payee
must surrender this Note to Maker to collect Principal payments.

3.       PUBLIC OFFERING.

Maker currently plans to file a S-1  Registration  Statement (the  "Registration
Statement")  with the  Securities  and Exchange  Commission  (the  "Commission")
covering a public offering (the "Public Offering") of its securities.

4.       CONVERSION.

(a) Payee's right to Convert.  Payee shall have the right, at any time until the
Principal  is paid in full,  to cause the  conversion  of all or any portion (if
such  portion  is One  Thousand  [$1,000]  Dollars  or a whole  multiple  of One
Thousand  [$1,000]  Dollars)  of the  Principal  outstanding  at the  time  such
conversion  is effected into shares of Common Stock (the  "Underlying  Shares").
The price for  conversion,  subject to  adjustment as provided  below,  shall be
Three  ($3.00)  Dollars  per  share.  If the  Public  Offering  is  successfully
completed, the Payee must accept repayment of this Note at the closing unless he
has  previously  exercised  his right to convert.  On  conversion  no payment or
adjustment for interest will be made.  Maker will round to the nearest share for
any fractional share.

(b) Mandatory Conversion. In the event that the Public Offering is not completed
by July 31, 1996 (the "Mandatory  Conversion Date"),  Payee shall be required to
convert the Principal into Common Stock at a price of Three ($3.00)  Dollars per
share unless Maker shall have repaid this Note,  together with accrued interest,
on or prior  thereto.  Maker shall pay all  accrued  but unpaid  interest on the
conversion  date to Payee on the date  upon  which  the  Underlying  Shares  are
delivered to Payee as provided in Paragraph 4(c) below.

(c) Manner of  Conversion.  Payee may  exercise his  conversion  right by giving
notice  thereof to Maker  setting forth the amount of Principal to be converted.
Within 15 days after the giving of such notice or the Mandatory Conversion Date,
as the case may be, Maker shall issue the number of Underlying Shares into which
the Principal is to be converted in  accordance  with the  conversion  price and
deliver to Payee a certificate or certificates therefor, registered in his name,
representing  such Shares against  delivery to Maker of this Note marked paid in
full. If only a portion of the Principal then  outstanding  is converted,  Maker
shall  deliver  to Payee,  together  with the  aforesaid  certificate(s),  a new
promissory note, in form and substance  identical to this Note,  except that the
principal  amount  thereof  shall  equal  that  portion  of the  Principal  then
outstanding  which has not been  converted.  Payee shall represent in writing to
Maker  prior to the  receipt of the  Underlying  Shares that such Shares will be
acquired  by him for  investment  only and not for  resale or with a view to the
distribution  thereof,  and shall agree that any  certificates  representing the
Shares may bear a

legend,  conspicuously  noting such restriction,  as Maker shall deem reasonably
necessary  or desirable  to enable it to comply with any  applicable  federal or
state laws or regulations.

5.       ADJUSTMENT IN CONVERSION PRICE.

(a) Adjustment  for Change in Capital  Stock.  Except as provided in Paragraph 5
(m) below, if Maker shall (i) declare a dividend on its outstanding Common Stock
in shares of its capital  stock,  (ii) subdivide its  outstanding  Common Stock,
(iii) combine its outstanding  Common Stock into a smaller number of shares,  or
(iv) issue any shares of its  capital  stock by  reclassification  of its Common
Stock (including any such reclassification in connection with a consolidation or
merger in which Maker is the continuing corporation), then in each such case the
conversion  privilege and the conversion  price in effect  immediately  prior to
such action shall be adjusted so that if the Note is thereafter  converted Payee
may receive the number and kind of shares which he would have owned  immediately
following  such action if he had  converted the Note  immediately  prior to such
action.  Such adjustment  shall be made  successively  whenever such event shall
occur. The adjustment shall become effective  immediately  after the record date
in the case of a dividend or distribution  and  immediately  after the effective
date in the case of a subdivision, combination or reclassification.  If after an
adjustment  Payee upon conversion of this Note may receive shares of two or more
classes of capital stock of Maker,  Maker's Board of Directors  shall  determine
the allocation of the adjusted  conversion  price between the classes of capital
stock. After such allocation,  the conversion  privilege and conversion price of
each class of capital  stock shall  thereafter be subject to adjustment on terms
comparable to those applicable to Common Stock in this Section 5.

(b) Adjustment for Certain Issuances of Common Stock. If Maker shall at any time
or from time to time issue any shares of Common Stock (other than shares  issued
as a dividend  or  distribution  as  provided  in  Paragraph  5 (a) above) for a
consideration  per share less than the conversion price in effect on the date of
such issue,  then,  forthwith upon such issue,  the  conversion  price in effect
immediately  prior to such action (the  "Existing  Conversion  Price")  shall be
reduced by dividing the number of shares so issued by the total number of shares
outstanding  after such  issuance,  multiplying  the quotient by the  difference
between the Existing  Conversion Price and the price of the shares so issued and
subtracting  the result from the Existing  Conversion  Price.  In the case of an
issue of additional shares of Common Stock for cash, the consideration  received
by Maker therefor shall be deemed to be the net cash proceeds  received for such
shares,  excluding  cash  received  on account of  accrued  interest  or accrued
dividends and after  deducting  therefrom any and all  commissions  and expenses
paid or incurred by Maker for any  underwriting  of, or otherwise in  connection
with, the issue of such shares.  The term "issue" shall be deemed to include the
sale or other  disposition  of shares  held in Maker's  treasury.  The number of
shares  outstanding  at any given  time  shall  not  include  shares in  Maker's
treasury.

(c)  Subscription  Offerings.  In case Maker shall  issue  rights,  options,  or
warrants to all  holders of Common  Stock  entitling  them to  subscribe  for or
purchase Common Stock (or securities convertible into or exchangeable for Common
Stock) at a price per share (or having a conversion price per share, in the case
of a security  convertible  into or exchangeable for Common Stock) less than the
Current  Market  Price  per  share of Common  Stock on the  record  date for the
determination of stockholders entitled to receive such rights, then in each such
case   the   conversion   price   shall   be   adjusted   by   multiplying   the
conversion    price   in   effect   immediately    prior   to    such

record date by a fraction,  of which the numerator shall be the number of shares
of Common  Stock  outstanding  on such  record date plus the number of shares of
Common Stock which the aggregate offering price of the total number of shares of
Common Stock so to be offered (or the aggregate initial  conversion price of the
convertible  securities so to be offered) would purchase at such "current market
price"  and of which  the  denominator  shall be the  number of shares of Common
Stock  outstanding  on such record date plus the number of additional  shares of
Common  Stock to be offered  for  subscription  or  purchase  (or into which the
convertible  or   exchangeable   securities  so  to  be  offered  are  initially
convertible or  exchangeable).  Such  adjustment  shall become  effective at the
close of business on such record date;  provided,  however,  that, to the extent
the shares of Common Stock (or securities  convertible  into or exchangeable for
shares of  Common  Stock)  are not  delivered,  the  conversion  price  shall be
readjusted after the expiration of such one of such rights, options, or warrants
(but only to the extent that this Note is not converted after such  expiration),
to the conversion  price which would then be in effect had the adjustments  made
upon the  issuance  of such  rights  or  warrants  been  made  upon the basis of
delivery of only the number of shares of Common Stock (or securities convertible
into or exchangeable  for shares of Common Stock) actually  issued.  In case any
subscription  price may be paid in a consideration part or all of which shall be
in a form  other  than  cash,  the  value  of  such  consideration  shall  be as
determined in good faith by Maker's  Board of Directors.  Shares of Common Stock
owned by or held for the account of Maker or any majority-owned subsidiary shall
not be deemed outstanding for the purpose of any such computation.

(d) Other Rights to Acquire Common Stock. In case Maker shall  distribute to all
holders  of  Common  Stock  (including  any  such   distribution   made  to  the
stockholders  of Maker in  connection  with a  consolidation  or merger in which
Maker is the continuing  corporation)  evidences of its  indebtedness  or assets
(other than cash dividends or distributions  and dividends  payable in shares of
Common Stock), or options or warrants or convertible or exchangeable  securities
containing  the right to  subscribe  for or  purchase  shares  of  Common  Stock
(excluding  those referred to in Paragraph 5 (c) above),  then in each such case
the conversion  price shall be adjusted by multiplying  the conversion  price in
effect   immediately   prior  to  the  record  date  for  the  determination  of
stockholders  entitled to receive such distribution by a fraction,  of which the
numerator  shall be the Current  Market  Price per share of Common Stock on such
record date,  less the fair market value (as determined in good faith by Maker's
Board of Directors) of the portion of the evidences of indebtedness or assets so
to be  distributed,  or of such  subscription  rights,  options,  or warrants or
convertible or exchangeable  securities containing the right to subscribe for or
purchase  shares of Common  Stock,  applicable  to one  share,  and of which the
denominator  shall be such Current Market Price per share of Common Stock.  Such
adjustment  shall be made  whenever  any such  distribution  is made,  and shall
become effective on the date of such distribution retroactive to the record date
for the determination of stockholders entitled to receive such distribution.

(e) Current Market Price. For the purpose of any computation  under Paragraphs 5
(c) and (d) above,  the "Current  Market Price" per share of Common Stock on any
date shall be deemed to be the  average of the daily  closing  prices for the 30
consecutive  trading  days  commencing  45 trading  days before  such date.  The
closing  price for each day shall be the last  reported  sales price regular way
or, in case no such reported sale takes place on such day, the closing bid price
regular way, in either case on the  principal  national  securities  exchange on
which the Common  Stock is listed or admitted to trading or, if the Common Stock
is not listed or admitted to trading on any national  securities  exchange,  the
highest  reported  bid  price  as  furnished  by  the  National  Association  of
Securities Dealers,  Inc. through NASDAQ or similar organization if NASDAQ is no
longer

reporting such information, or by the National Daily Quotation Bureau or similar
organization if the Common Stock is not then quoted on an inter-dealer quotation
system.  If on any  such  date  the  Common  Stock  is not  quoted  by any  such
organization,  the fair value of the Common Stock on such date, as determined by
Maker's Board of Directors, shall be used.

(f) Minimum Adjustment.  No adjustment in the conversion price shall be required
if such adjustment is less than $0.10;  provided,  however, that any adjustments
which by reason of this  Paragraph  5(f) are not  required  to be made  shall be
carried  forward  and taken  into  account  in any  subsequent  adjustment.  All
calculations  under this  Section 5 shall be made to the nearest  cent or to the
nearest one-hundredth of a share, as the case may be.

(g) Referral of  Adjustment.  In any case in which this Section 5 shall  require
that an adjustment in the conversion price be made effective as of a record date
for a specified  event,  if the Note shall have been converted after such record
date Maker may elect to defer  until the  occurrence  of such  event  issuing to
Payee the  shares,  if any,  issuable  upon such  conversion  over and above the
shares,  if any,  issuable upon such  conversion on the basis of the  conversion
price in effect prior to such adjustment;  provided,  however,  that Maker shall
deliver to Payee a due bill or other appropriate  instrument  evidencing Payee's
right to  receive  such  additional  shares  upon the  occurrence  of the  event
requiring such adjustment.

(h) Number of Shares.  Upon each adjustment of the conversion  price as a result
of the  calculations  made in Paragraphs 5(a) through (d) above,  the Note shall
thereafter  evidence the right to purchase,  at the adjusted  conversion  price,
that  number  of shares  (calculated  to the  nearest  thousandth)  obtained  by
dividing  (i)  the  product   obtained  by  multiplying  the  number  of  shares
purchasable  upon  conversion  of the Note prior to  adjustment of the number of
shares by the  conversion  price in effect prior to adjustment of the conversion
price by (ii) the  conversion  price in  effect  after  such  adjustment  of the
conversion price.

(i) When No Adjustment  Required.  No adjustment  need be made for a transaction
referred  to in  Paragraphs  5(a)  through  (d) above if Payee is  permitted  to
participate in the transaction on a basis no less favorable than any other party
and at a level which would preserve Payee's  percentage equity  participation in
the Common Stock upon  conversion of the Note.  No  adjustment  need be made for
sales of Common Stock pursuant to a Company plan for  reinvestment  of dividends
or interest,  the granting of options  and/or the exercise  options  outstanding
under any of Maker's  currently  existing stock option plans, or the exercise of
any other of Maker's currently  outstanding  options. No adjustment need be made
for a change in the par value or no par value of the Common  Stock.  If the Note
becomes  convertible  solely into cash, no adjustment  need be made  thereafter.
Interest will not accrue on the cash.

(j) Notice of Adjustment. Whenever the conversion price is adjusted, Maker shall
promptly  mail to Payee a notice of the  adjustment  together with a certificate
from Maker's independent public accountants briefly /stating the facts requiring
the adjustment and the manner of computing it. The certificate shall be evidence
that the adjustment is correct.



                                                                 
                               Page 5 of 11 Pages




Belmac Corporation
12% Convertible Subordinated
Promissory Note

(k) Voluntary Reduction. Maker from time to time may reduce the conversion price
by any  amount  for any  period of time if the period is at least 20 days and if
the reduction is irrevocable during the period. Whenever the conversion price is
reduced,  Maker shall mail to Payee a notice of the reduction.  Maker shall mail
the notice at least 15 days before the date the reduced  conversion  price takes
effect.  The notice shall state the reduced conversion price after the period it
will be in effect. A reduction of the conversion price does not change or adjust
the  conversion  price  otherwise  in effect for  purposes of  Paragraphs  5 (a)
through (d) above.

(l) Notice of Certain  Transactions.  If (i) Maker  takes any action  that would
require an adjustment  in the  conversion  price  pursuant to this Section 5; or
(ii) there is a liquidation or dissolution of Maker, Maker shall mail to Payee a
notice stating the proposed  record date for a distribution or effective date of
a  reclassification,  consolidation,  merger,  transfer,  lease,  liquidation or
dissolution.  Maker  shall  mail the notice at least 15 days  before  such date.
Failure to mail the notice or any defect in it shall not affect the  validity of
the transaction.

(m) Reorganization of Company. If Maker is a party to a merger, consolidation or
a transaction  in which it transfers or leases  substantially  all of its assets
which reclassifies or changes its outstanding Common Stock, the person obligated
to deliver  securities,  cash or other assets upon  conversion of the Note shall
assume the terms of this  Note.  If the issuer of  securities  deliverable  upon
conversion  of the Note is an affiliate of the  surviving,  transferee or lessee
corporation, that issuer shall join in such assumption. The assumption agreement
shall  provide  that the Payee may convert this Note into the kind and amount of
securities, cash or other assets which he would have owned immediately after the
consolidation,   merger,  transfer  or  lease  if  he  had  converted  the  Note
immediately  before  the  effective  date  of the  transaction.  The  assumption
agreement shall provide for adjustments  which shall be as nearly  equivalent as
may be  practical  to the  adjustments  provided  for in  this  Section  5.  The
successor company shall mail to Payee a notice briefly describing the assumption
agreement. If this Paragraph applies, Paragraph 5 (a) above does not apply.

(n) Maker  Determination  Final.   Any  determination that Maker or its Board of
Directors  must  make  pursuant  to  this  Section 5 shall be conclusive, absent
manifest error.

6.    INCLUSION OF SECURITIES IN REGISTRATION STATEMENT; RIGHT TO REGISTRATION.

(a) Payee's Right to Include  Securities in Registration  Statement.  Maker will
include  the Unit  Shares  owned  by  Payee  and the  Underlying  Shares  in the
Registration  Statement  on the  condition  that  Payee  provides  Maker and its
counsel,  in  a  timely  fashion,  with  all  information  Maker's  counsel  may
reasonably  require in order to effect such  inclusion.  Maker will use its best
efforts to have the Registration  Statement declared effective by the Commission
but no assurance to this effect can be given or, if the  Registration  Statement
is  declared  effective,  that the  Public  Offering  will ever be  successfully
completed.

(b) Payee's Right to Registration.  If the  Registration  Statement shall not be
declared  effective  by  December  31,  1995,  then upon  receipt of notice (the
"Registration  Request  Notice")  requesting  registration  of Unit  Shares  and
Underlying  Shares from the holders of the majority of such Shares,  on only one
occasion, after December 31, 1995 and before December 31, 1997, Maker will offer
to Payee the  opportunity  to include his Unit Shares and  Underlying  Shares in
such  registration.  Maker will use its best efforts to file with the Commission
as promptly 
                                            
                               Page 6 of 11 Pages




Belmac Corporation

as practicable,  a registration statement (the "Demand Registration Statement"),
utilizing year end audited financial  statements,  and will use its best efforts
to  have  the  Demand  Registration  Statement  declared  effective  and  remain
effective  until the  earlier  of nine  months or the date all Unit  Shares  and
Underlying  Shares  registered  thereby have been sold.  Maker will also use its
best  efforts  to  qualify  the Unit  Shares  and  Underlying  Shares  under the
securities  laws of the state where Payee resides.  This offer to Payee shall be
made within 20 days after Maker receives the Registration  Request Notice.  This
demand  registration  right may be exercised  one time only.  If Payee elects to
include  his Unit  Shares  and  Underlying  Shares  in the  Demand  Registration
Statement, he will, in a timely fashion, provide Maker and its counsel with such
information and execute such documents as Maker's counsel may reasonably require
to prepare and process the registration statement.

(c)      Copies of Registration Statements and Prospectuses.  Maker will provide
Payee  with a copy of the  Registration  Statement  or the  Demand  Registration
Statement,  as the case may be,  and any  amendment  thereto,  and copies of the
final  prospectus  included  therein in such  quantities  as may  reasonably  be
required  to  permit  Payee to sell his Unit and  Underlying  Shares  after  the
Registration Statement or Demand Registration Statement is declared effective by
the Commission.

(d) Maker's  Obligation  to Bear Expenses of  Registration.  Maker will bear all
expenses (except  underwriting  discounts and commission,  if any, and the legal
fees and expenses, if any, of counsel to Payee,) necessary and incidental to the
performance of its obligations under this Section 6.

7.       SUBORDINATION; PARI PASSU WITH OTHER NOTES.

The Note is subordinated to Senior Debt,  which is the principal of and premium,
if any,  and interest  (including  post-petition  interest,  if any) on, and any
other  payment due pursuant to the terms of  instruments  creating or evidencing
Indebtedness  of  Maker  outstanding  on the date of this  Note or  Indebtedness
thereafter created,  incurred,  assumed or guaranteed by Maker and all renewals,
extensions and refunding thereof, which is payable to banks or other traditional
long-term  institutional  lenders such as insurance companies and pension funds,
unless in the instrument  creating or evidencing  such  Indebtedness,  it is not
provided  that such  Indebtedness  is senior in right of  payment  to this Note.
Notwithstanding  the  foregoing,  Senior  Debt  with  respect  to  Maker  or any
subsidiary  thereof shall not include (i) any  Indebtedness of Maker to any such
subsidiary  for money  borrowed or advanced  from such  subsidiary  and (ii) any
Indebtedness   representing   the  redemption  price  of  any  preferred  stock.
"Indebtedness",  as applied to any entity means any indebtedness,  contingent or
otherwise,  in respect of borrowed  money  (whether  or not the  recourse of the
lender  is to the  whole  of the  assets  of such  entity  or only to a  portion
thereof),  or evidenced by bonds,  notes,  debentures or similar  instruments or
letters  of credit,  or  representing  the  balance  deferred  and unpaid of the
purchase price of any property or interest therein, except any such balance that
constitutes a trade payable,  if and to the extent that such indebtedness  would
appear  as a  liability  upon a  balance  sheet  of such  entity  prepared  on a
consolidated basis in accordance with generally accepted accounting  principles.
Senior Debt must be paid before the Note may be paid. This Note shall be paid on
a pari passu  basis with all other  Notes.  Upon  request of Maker  Payee  shall
execute such  subordination  agreements  with holders of Senior Debt as shall be
reasonably requested.

8.       COVENANTS OF MAKER.

Maker  covenants  and agrees  that from and after the date  hereof and until the
date of repayment in full of the Principal  and  Interest,  it shall comply with
the following conditions:

(a)  Maintenance  of Existence and Conduct of Business.  Maker shall,  and shall
cause  each  of its  subsidiaries  to (i) do or  cause  to be  done  all  things
necessary to preserve and keep in full force and effect its corporate  existence
and  rights;  and (ii)  continue to conduct  its  business so that the  business
carried on in connection therewith may be properly and advantageously  conducted
at all times.

(b) Books and Records.  Maker shall, and shall cause each of its subsidiaries to
use its  reasonable  efforts to keep adequate  books and records of account with
respect to its business activities.

(c) Insurance.  Maker  shall use its reasonable  efforts  to  maintain insurance
