                                  AMENDED NOTE

                                DECEMBER 28, 2007

1. BORROWER'S PROMISE TO PAY

     In consideration for the sale, assignment and transfer of certain assets to
the undersigned by Daycon Investors Associates, Inc. ("Holder") pursuant to that
certain  Amended  Asset  Purchase & Royalty  Agreement  dated as of December 28,
2007,  we  ("Maker")  promise  to pay U.S.  $250,000.00  (this  amount is called
"principal"),  without  interest,  to the order of the  Holder  pursuant  to the
following terms:

     (a) $25,000 on or before January 4, 2008, as a result of Cavit's  financing
commitment.

     (b) 20% of gross amount of additional  financing  received by Cavit,  until
this $250,000 Note is paid in full.

2. BORROWER'S RIGHT TO PREPAY

     We have the right to make payments of principal at any time before they are
due.  A payment of  principal  only is known as a  "prepayment."  When we make a
prepayment, we will tell the Holder in writing that we are doing so.

3. BORROWER'S FAILURE TO PAY AS REQUIRED

     (A) DEFAULT

     If we do not pay the principal  balance of this Note on the date it is due,
we will be in default.

     (B) NOTICE OF DEFAULT

     If we are in default,  the Holder may send us a written  notice  telling us
that if we do not pay the  overdue  amount by a certain  date,  the  Holder  may
require us to pay  immediately  the full amount of principal  which has not been
paid.

     (C) PAYMENT OF HOLDER'S COST AND EXPENSES

     If the Holder  has  required  us to pay  immediately  in full as  described
above,  the Note Holder will have the right to be paid back by us for all of its
costs and  expenses  in  enforcing  this Note to the  extent not  prohibited  by
applicable law. Those expenses include, for example, reasonable attorney's fees.
Notwithstanding the foregoing, in the event that Maker is unable to raise equity
capital in an amount  sufficient to pay this Note in full on the maturity  date,
and Maker has used its best  efforts to raise such  equity  capital,  then Maker
shall execute  appropriate  assignments,  bills of sale, etc. necessary to cause
the assets  acquired from Holder by Maker to become the sole property of Holder,
whereupon  this Note  shall be  cancelled  and no money  shall be due from Maker
hereunder.

ARTICLE 1

TERM

Term of Lease

ss. 1.01.  The term of this lease is one year,  beginning on January 1, 2008 and
ending on December 31, 2008 unless  terminated sooner or extended as provided in
this lease.

Option To Extend Term

ss. 1.02.  Tenant may extend this lease beyond the  expiration  date provided in
ss. 1.01 on the following conditions:

(a) Tenant may, if it fully and faithfully  complies with this lease, extend the
lease term for 1 year.  The extended  term will begin on the day  following  the
expiration  date of the lease term  specified in ss. 1.01,  and for 4 additional
periods of the same length,  each to begin on the day following  the  expiration
date of the  immediately  preceding  extended  term.  But if,  on the  date  the
original  term or any extended  term  expires,  Tenant is in default  beyond any
grace  period  provided  in this  lease in  performing  any of the terms of this
lease,  the remaining option or options are void. All the terms and covenants of
the original lease term apply to all extended lease terms.

(b) Tenant may  exercise  each  option to extend  this lease by giving  Landlord
notice of its  intention  to do so not later than 30 days  before the lease term
<PAGE>
expires,  in the case of the initial  option to extend,  or before the  extended
lease term expires,  in the case of successive  options to extend.  Notice of an
intention to exercise an option under this lease must, to be effective,  be sent
by certified or registered mail to Landlord at 400 Poinciana  Drive,  Hallandale
Beach, FL 33009 and be postmarked no later than the latest date provided in this
section for Tenant's exercising the option.

Holdover

ss. 1.03. If Tenant holds over and continues in possession of the premises after
the lease term (or any  extension of it) expires,  other than as provided in ss.
1.02, Tenant will be considered to be occupying the premises on a month-to-month
tenancy, subject to all of the terms of this lease.

ARTICLE 2

RENT

Basic Rent

ss. 2.011 Tenant will pay Landlord  $5,337.34  per month,  from the beginning of
the lease  term and  throughout  the  original  lease  term,  in  advance on the
fifteenth  (15th) day of each month.  This amount is the "basic  rent." Rent for
any fractional  month at the beginning or end of the lease term will be prorated
on a per-day basis.  This basic rent will increase by ten (10%) percent for each
extended lease term.

Leasehold Improvement Fee

ss. 2.012 In consideration of Landlord having expended  approximately $45,000 to
make premises  suitable for Tenant's  needs,  Tenant agrees to pay an additional
$14,000  for the first  month of this  lease and an  additional  $7,750  for the
second through fifth month of this lease, in addition to the basic rent above in
section 2.011.

Security Deposit

ss. 2.02 Tenant will  deposit with  Landlord  $5,337.34 as security for Tenant's
fully and faithfully  performing  the terms of this lease.  This deposit will be
made no later than Tenant's occupancy of the premises.

Security Deposit as Landlord's Remedy

ss. 2.03 Landlord may apply all or any part of the deposit  required in ss. 2.02
of this article to cure any default of Tenant  under this lease.  In that event,
Tenant  must  deposit  with  Landlord  the amount  applied  to cure its  default
immediately on notice from Landlord of the nature and amount of the application.

                                       2
<PAGE>
Effect of Transfer of Premises

ss. 2.04 If Landlord  transfers  its interest in the  premises  during the lease
term, it may either: (a) return the deposit to Tenant, plus interest at the rate
of five (5%) percent annually,  minus any deductions made under Section ss. 2.03
of this  article and not replaced by Tenant;  or (b) transfer the deposit,  plus
interest at the rate of five (5%) percent  annually,  minus any deductions  made
under Section ss. 2.03 of this article and not replaced by Tenant, to Landlord's
successor in interest.  If Landlord  transfers all or any portion of the deposit
under this  section,  on  transfer  Landlord  will be relieved of all rights and
obligations with regard to the deposit,  and all of these rights and obligations
will accrue to the  transferee.  Landlord  must give  Tenant  notice of any such
transfer,  including  the name and  address  of the  transferee  and the  amount
transferred.

Return of Security Deposit

ss. 2.05 Landlord  must return the deposit to Tenant,  with interest at the rate
of percent  annually,  minus any amounts deducted under ss. 2.03 of this article
that have not been  replaced  by  Tenant,  no later  than 30 days  after  Tenant
surrenders possession of the premises to Landlord.  The deposit must be returned
as provided in this section to the address left with Landlord by Tenant for this
purpose or, if no such address was left, at Tenant's last known address.

Increased Operating Costs

ss. 2.06 If Landlord's  costs,  as  determined  by its  auditors,  of owning and
maintaining  the  Building,  including the parking  garage and other  facilities
maintained  for the benefit of the Building or its tenants,  during any calendar
month of the lease term,  exceeds the average  monthly cost for the first twelve
(12) months of the term,  Tenant will pay to Landlord  each month  thereafter an
amount  representing  Tenant's  proportionate  share of the increased cost. This
amount is referred to as "additional rent" under this lease.

(a)  Landlord  must make written  demand of Tenant for the amount of  additional
rent due to effectuate  this section.  Landlord's  failing to demand  payment of
additional  rent to cover increased  operating  costs does not waive  Landlord's
right  to  claim  the  additional  rent  in the  future,  but no  assessment  of
additional rent under this paragraph may be made retroactive.

(b)  Tenant's   proportionate  share  of  the  increased  costs  of  owning  and
maintaining  the  Building is computed by  dividing  the total  rentable  square
footage of the Building by the total square  footage of the leased  premises and
multiplying  the  increase in the monthly  operating  expenses by the  resulting
percentage  figure.  The total rentable square footage is computed by taking the
total square footage of the Building and  subtracting  the square footage of all
common areas, storage areas, areas required for heating or air conditioning,  or
other  equipment  required to service or maintain the Building and the basement.
It includes any space occupied by Landlord as office space.

                                       3

Additional Real Estate Taxes

ss. 2.07 If the real estate taxes attributable to the premises and applicable to
the calendar year beginning  January 1, 2008 or to any calendar year  thereafter
during  which the  premises  are fully  assessed,  exceed the real estate  taxes
attributable  to the premises and  applicable  to the  calendar  year  beginning
January 1, 2007, Tenant must pay Landlord as additional rent the portion of such
excess attributable to the premises.  The additional rent must be paid in twelve
(12) equal monthly  installments  beginning on December 1st of the calendar year
immediately  succeeding the calendar year in which such excess occurs.  However,
any such additional rent is not due and payable beyond the term of this Lease or
its renewal.

Notice of Excess

ss. 2.08 On or before  December 31, 2008,  and on or before  December 31 of each
subsequent  calendar year, the Landlord must give the Tenant a written statement
showing the computation of such excess, if any, for the preceding  calendar year
and  showing  the amount of  additional  rent for which the Tenant is  obligated
under ss. 2.09.

Computation of Excess

ss. 2.09 To determine the  applicability  of real estate taxes for each calendar
year, real estate taxes levied on the basis of a tax year that does not coincide
with a calendar  year will be deemed to apply 1/12th to each  calendar  month in
the tax year. The portion of real estate taxes attributable to the premises will
be deemed to be equal to the product  obtained by multiplying the increased real
estate  taxes  assessed  against the Building  (including  the land on which the
Building  is  situated)]  by a  fraction,  the  numerator  of which is the gross
square-foot  area of the leased premises  (2301.56) and the denominator of which
is the gross  square  foot area of the  Building  as it existed at the time this
lease was executed.

Property Tax Notice and Revision

ss. 2.10 Landlord must notify Tenant  promptly on receipt of any real estate tax
assessment  notice received from the taxing  authorities.  On Tenant's  request,
Landlord must seek redress from the taxing  authority  following the  procedures
provided by law. If such redress is denied, Landlord must promptly notify Tenant
of  the   denial.   On   Tenant's   request,   Landlord   must  be  required  to
administratively appeal the denial following the procedures provided by law.

ARTICLE 3

USE OF PREMISES

Permitted Use

ss. 3.01.  Tenant represents and warrants to Landlord that Tenant intends to use
the premises only for a nutritional and surgical instrumentation  laboratory and
storage space, respectively. Tenant's use of the premises is restricted to those
purposes  specified in this section,  unless Landlord gives Tenant prior written
consent for a different use.

including Hazardous Materials Laws.

(b) Tenant,  at its sole cost, must comply with all Hazardous  Materials Laws in
connection with Tenant's use of the premises. If Tenant stores, uses or disposes
of any other Hazardous Materials on the premises, Tenant must notify Landlord in
writing at least five (5) days prior to their first  appearance on the premises,
and Tenant's failure to do so is a default under the lease.

ARTICLE 6

ALTERATIONS, ADDITIONS, IMPROVEMENTS, AND FIXTURES

Consent of Landlord

ss. 6.01. Tenant may not make any alterations, additions, or improvements to the
premises without Landlord's prior written consent. Landlord may not unreasonably
withhold consent for nonstructural alterations, additions, or improvements.

Property of Landlord

ss. 6.02. All alterations, additions, or improvements made by Tenant will become
Landlord's property when this lease terminates. But Tenant must promptly remove,
if Landlord so elects,  all alterations,  additions,  and improvements,  and any
other  property  placed in or on the premises by Tenant,  and Tenant must repair
any damage caused by the removal.

Trade Fixtures

ss. 6.03.  Tenant has the right at all times to erect or install  furniture  and
fixtures,  as long as Tenant  complies with all  applicable  governmental  laws,
ordinances,  and  regulations.  Tenant  may  remove  such  items when this lease
terminates,  if Tenant is not in  default at that time and the  fixtures  can be
removed without structural damage to the premises. Before this lease terminates,
Tenant must repair any damage caused by removing any fixtures.  Any furniture or
fixtures  not  removed  by Tenant  when this  lease  terminates  are  considered
abandoned by Tenant and automatically become Landlord's property.

Alterations Required by Accessibility Laws

ss. 6.04. (a) Tenant is responsible for making any  alterations,  additions,  or
improvements  to  the  premises  that  are  mandated  by   accessibility   legal
requirements ("accessibility alterations").  The allocation of responsibility to
Tenant for compliance with accessibility  legal requirements with respect to the
premises is a material inducement for the parties to enter this lease.

(b)  Landlord  will  reimburse  Tenant for all  reasonable  out-of-pocket  costs
incurred by Tenant in making the  accessibility  alterations  within thirty (30)
days after Tenant submits a written demand along with supporting  documentation.
The cost of these  accessibility  alterations  for  which  Tenant  has  received
reimbursement  from  Landlord  will  be  amortized  over  their  useful  life as
reasonably  agreed by the parties,  together  with  interest on the  unamortized
balance at the rate of three (3%)  percent per year,  and will be paid by Tenant
to Landlord as additional rent.

(c) Before  undertaking the  accessibility  alterations,  Tenant must deliver to
Landlord a detailed cost breakdown of the accessibility  alterations.  This cost
breakdown  is  subject  to  Landlord's  reasonable  approval.  Tenant  must  use
reasonable  efforts to minimize  the cost of the  accessibility  alterations  by
coordinating   them  with  Tenant's   undertaking  of  other   alterations   and
improvements on the premises. Unless Landlord otherwise agrees, Tenant must seek

the lease term, Landlord must, at its sole cost and risk, proceed immediately to

in part, the rent payable during the period in which they are untenantable  will
be adjusted  equitably.  If Landlord fails to complete the rebuilding or repairs
within 180  working  days after the date of  Tenant's  written  notification  to
Landlord of the  occurrence of the damage,  Tenant may  terminate  this lease by
written  notification  to  Landlord.  Upon  the  notification,  all  rights  and
obligations under this lease will cease.

(b) If the premises are partially destroyed in the final three (3) months of the
lease term, Landlord need not rebuild or repair the premises. If Landlord elects
not to rebuild or repair,  and the damage rendered the premises  untenantable in
whole or in part,  Tenant may  terminate the lease or continue it, with the rent
for the remainder of the lease period adjusted equitably.

demands, damages, costs, and expenses, including reasonable attorney's fees, for
defending  claims and demands arising from the conduct or management of Tenant's
business  on the  premises  or its use of the  premises,  or from any  breach on
Tenant's part of any conditions of this lease,  or from any act or negligence of
Tenant, its officers, agents, contractors, employees, subtenants, or invitees in
or about the  premises.  In case of any  action or  proceeding  brought  against
Landlord by reason of any such claim,  Tenant,  on notice  from  Landlord,  will
defend the action or proceeding by counsel acceptable to Landlord.

Tenant's Environmental Indemnity

ss. 12.02. (a) Tenant is responsible only for the payment of that portion of any
cleanup costs for the premises necessary for compliance with Hazardous Materials
Laws that arise as a result of Tenant's discharge of Hazardous  Materials on the
premises during Tenant's occupancy of the premises.  Landlord is responsible for
all other  cleanup  costs and for  ensuring  that any  other  responsible  party
participate in the cleanup to the extent of its responsibility for a release.

(b) Tenant must indemnify,  defend,  and hold harmless Landlord from and against
all claims,  liabilities,  losses,  damages, and costs,  foreseen or unforeseen,

Insurance

ss. 12.03.  Tenant  agrees to obtain an insurance  policy issued in the names of
the  Landlord and Tenant for any  negligence  or  intentional  acts by Tenant or
Tenant's  employees  or guests  while on or in the  premises  and the  adjoining

hazard that is not covered by the aforementioned  coverage obtained above caused
by Tenant, Tenant's employees or guests.

ss. 12.04.  Landlord  agrees to promptly pay Tenant for any loss of inventory or
product  or  business  interruption  that  Tenant  may  incur,  as a  result  of
Landlord's  negligence in failing to provide the services  specified in ss. 4.01
above, that are not covered by Tenant's insurance company. If default in payment
of the loss  continues for 20 days after  Tenant's  written  notice to Landlord,
Tenant may, at its option, pay the loss or any portion of it, or deduct the loss
or any portion of it from future  Basic Rent or Leasehold  Improvement  Fees due
Landlord as  specified  in ss. 2.011 and ss.  2.022,  respectively.  Any amounts

DEFAULT

ss.14.01.  The following events are considered events of default by Tenant under
this lease:

(a) Tenant fails to pay any  installment  of rent due under this lease,  and the
failure continues for 10 days.

(b) Tenant  fails to comply with any term or covenant of this lease,  other than
the payment of rent,  and does not cure the failure within 20 days after written
notice of the failure to Tenant.

(c) Tenant makes an assignment for the benefit of creditors.

(d) Tenant deserts or vacates any  substantial  portion of the premises for five
or more days.

Landlord's Remedies

ss.14.02. If any default specified inss.14.01 occurs, Landlord may pursue one or
more of the following remedies:

(a) Without notice to Tenant,  Landlord may terminate this lease, in which event
Tenant must  immediately  surrender  the premises to Landlord.  Tenant will,  on
demand,  pay Landlord the amount of all loss and damage that Landlord suffers by
reason of the  termination,  whether through  inability to relet the premises on
satisfactory terms or otherwise.

(b)  Landlord  may  enter on and take  possession  of the  premises;  relet  the
premises on the terms Landlord considers advisable; and receive the rent for the
reletting. Tenant will, on demand, pay Landlord any deficiency that may arise by
reason of reletting.

                                       13
<PAGE>
(c) Landlord  may enter the  premises and do whatever  Tenant is obligated to do
under the terms of this lease to correct the default.  Tenant  will,  on demand,
reimburse Landlord for any expenses that Landlord incurs in effecting compliance
with Tenant's  obligations  under this lease in this manner,  and Tenant further
releases  Landlord from liability for any damages  resulting to Tenant from such
an action.

No reentry or taking  possession of the premises by Landlord may be construed as
an election on its part to terminate this lease,  unless a written notice of the
intention is given to Tenant. Notwithstanding any reletting or reentry or taking
possession,  Landlord  may at any time  thereafter  terminate  this  lease for a
previous  default.  The loss or damage that  Landlord may suffer in  terminating
this lease, or the deficiency from any reletting as provided above, includes the
expense of repossession.

Landlord's Lien

ss. 14.03.  (a) Landlord has, at all times, a valid security  interest to secure
payment of all  rentals  and other sums of money  becoming  due under this lease
from  Tenant and to secure  payment of any  damages  or loss that  Landlord  may
suffer by reason of Tenant's  breaching  any covenant,  agreement,  or condition
contained  in this  lease.  This  security  interest  covers all  goods,  wares,
equipment,  fixtures,  furniture,  and other personal property of Tenant that is
now on the  premises  or placed on the  premises  at some  later  date,  and all
proceeds from them.  This property may not be removed from the premises  without
Landlord's consent until all arrearages in rent and all other sums of money then
due  Landlord  under  this  lease  have  been paid and  discharged,  and all the
covenants,  agreements,  and  conditions of this lease have been fully  complied
with and performed by Tenant.

(b) If Tenant is in default,  Landlord  may,  in addition to any other  remedies
provided in this lease or by law, after giving  reasonable  notice of the intent
to take possession and giving an opportunity  for a hearing on the issue,  enter
on the premises and take possession of any goods,  wares,  equipment,  fixtures,
furniture,  and other  personal  property of Tenant  situated  on the  premises,
without liability for trespass or conversion.  Landlord may sell the property at
public or private sale,  with or without having the property at the sale,  after
giving Tenant  reasonable  notice of the time and place of any public sale or of
the time after which any private sale is to be made. Landlord or its assigns may
buy any items to be sold at the sale unless they are prohibited from doing so by
law. Unless otherwise provided by law, and without excluding any other manner of
giving Tenant reasonable  notice,  the  reasonable-notice  requirement is met if
notice is given at least fifteen (15) days before the time of sale. The proceeds
from any such disposition,  less any expenses  connected with taking possession,
holding,  and selling the property  (including  reasonable  attorney's  fees and
other expenses), will be applied as a credit against the indebtedness secured by
the  security  interest  granted in this  section.  Any surplus  will be paid to
Tenant or as  otherwise  required by law,  and Tenant will pay any  deficiencies
immediately.

(c) When  Landlord  requests,  Tenant  will  execute  and  deliver to Landlord a
financing  statement in sufficient form to perfect Landlord's  security interest
in the property and proceeds  under the Uniform  Commercial  Code. The statutory
lien for rent is not waived as the contractual security interest granted in this
article supplements the statutory lien.

                                       14
<PAGE>
Landlord's Default

ss.14.04.  (a) If Landlord  defaults  in  performing  any term or covenant  that
Landlord  must  perform  under  this  agreement,  Tenant  may do  either  of the
following:

(i) After not fewer than seven (7) days' notice to  Landlord,  Tenant may remedy
the default by any necessary action and, in connection with this remedy, may pay
expenses  and employ  counsel.  Landlord  must,  on demand,  pay Tenant all sums
expended  or  obligations  incurred  by  Tenant  in  connection  with  remedying
Landlord's  default.  Tenant  may, if not  reimbursed,  in addition to any other
right or remedy that it may have,  deduct these costs from rent subsequently due
under this lease.

(ii) Tenant may  terminate  this lease by giving at least seven (7) days' notice
to Landlord of its  intention.  If Tenant  chooses this  option,  the lease will
terminate on the date designated in Tenant's  notice,  unless Landlord has cured
the default before the seven-day period expires.

(b)  Landlord's  default  does not give Tenant the right to withhold  payment of
rent during the lease term.

Cumulative Remedies

ss. 14.05. By pursuing any remedy provided in this lease,  neither  Landlord nor
Tenant is precluded  from  pursuing  any other remedy  provided in this lease or
provided by law. Either party's pursuing any remedy provided in this lease or by
law is not a  forfeiture  or waiver of any damages  accruing to either  party by
reason of  violating  any term or covenant of this  lease.  Nor will  Landlord's
pursuing any remedies  provided in this lease  constitute a waiver or forfeiture
of any rent due under this lease.

Waiver of Default

ss. 14.06. Either party's waiving any default or violation or breach of any term
or  covenant of this lease does not waive any other  violation  or breach of any
term or covenant of the lease. Nor does either party's forbearing to enforce one
or more of the  remedies  provided in this lease or by law upon a default  waive
the default.  Landlord's  accepting rent following default under this lease does
not waive the default.

Surrender of Premises

ss.  14.07 No act done by  Landlord  or its agents  during the lease term may be
considered an  acceptance  of a surrender of the  premises,  and no agreement to
accept a surrender of the premises is valid unless in writing and  subscribed by
Landlord.
