                           CONVERTIBLE PROMISSORY NOTE

$7,000,000.00                  Dallas, Texas                     July 10, 2008

         FOR VALUE RECEIVED,  the undersigned,  Implantable Vision, Inc., a Utah
corporation, and its successors and assigns ("Borrower"), promises to pay to the
order of Lariat Energy Corporation, a Nevada corporation, and its successors and
permitted  assigns  ("Holder"),  the  principal  sum of  Seven  Million  Dollars
($7,000,000.00),  together with simple  interest from the date of advancement on
the principal  balance hereof from time to time remaining  unpaid at an interest
rate equal to the U.S. prime rate as published in the Wall Street Journal Online
plus one  percent  (1%) per annum,  determined  on the date of this  Convertible
Promissory Note (the "Note"),  and adjusted on each  anniversary  until maturity
(subject to Section 2 of this Note),  both  principal and interest being payable
at the  address  designated  in Section 12, or at such other place as Holder may
from time to time designate in writing.

         The  principal of this Note shall mature and be due and payable on July
10, 2010. All accrued and unpaid  interest shall be due and payable  immediately
on maturity.

         All past due  principal  and  accrued  interest on this Note shall bear
interest  from  maturity  (whether  on demand,  upon  acceleration  of  maturity
following an Event of Default (as defined below) or otherwise) until paid at the
lesser of (i) the rate of  twelve  percent  (12%) per annum or (ii) the  highest
rate for which Borrower may legally  contract under applicable law. All payments
hereunder shall be payable in lawful money of the United States of America which
shall be legal tender for public and private debts at the time of payments.

1.       Conversion.

     (a) Conversion Option. This Note shall be convertible at the
option of Holder  hereof (the  "Optional  Conversion"),  in whole or in part, in
lieu of and in satisfaction of the unpaid principal hereunder,  into that number
of fully paid and nonassessable shares of Common Stock (as defined in Section 2)
as is equal to the quotient of the unpaid  principal  divided by the  applicable
Conversion  Price (as defined in Section 2). Upon any Optional  Conversion,  the
outstanding  principal due under this Note shall be reduced in full by an amount
equal to the  number  of  shares of Common  Stock  issued  upon such  conversion
multiplied by the applicable Conversion Price.

     (b) Conversion Procedures.  If Holder is entitled to and desires to convert
this Note into Common  Stock,  it shall  surrender  this Note to Borrower at its
principal  executive  offices,  accompanied by proper instruments of transfer to
Borrower or in blank, accompanied by irrevocable written notice to Borrower that
Holder  elects so to convert  this Note and the name or names (with  address) in
which a certificate or certificates for Common Stock are to be issued.  Borrower
shall, as soon as practicable  after such written notice and compliance with any
other  conditions   herein   contained,   deliver  at  such  office  to  Holder,
certificates  for the number of full shares of Common Stock to which it shall be
entitled.  Such  conversion  shall be deemed to have been made as of the date of
such  surrender  of this Note,  and the person or  persons  entitled  to receive
Common Stock or other  securities  deliverable  upon conversion shall be treated
for all purposes as the record holder or holders thereof on such date.

     (c) Certain Adjustments.  The applicable Conversion Price and the number of
securities  issuable upon conversion of this Note shall be subject to adjustment
from time to time as follows:

<PAGE>

                           (i) In case Borrower shall at any time after the date
         hereof (1) pay a dividend or make a  distribution  on its capital stock
         that is paid or made in shares of stock of Borrower,  (2) subdivide its
         outstanding  shares of Common Stock into a greater  number of shares or
         (3)  combine  its  outstanding  shares of Common  Stock  into a smaller
         number of  shares,  then in each such  case the  applicable  Conversion
         Price in effect  immediately prior thereto and the securities  issuable
         shall be  adjusted  retroactively  as  provided  below  so that  Holder
         thereafter  shall be entitled to receive the number of shares of Common
         Stock of  Borrower  and other  shares and rights to  purchase  stock or
         other securities which Holder would have owned or have been entitled to
         receive  after the happening of any of the events  described  above had
         this Note been  converted  immediately  prior to the  happening of such
         event or any  record  date with  respect  thereto.  In the event of the
         redemption of any shares  referred to in clause (1),  Holder shall have
         the right to receive,  in lieu of any such shares or rights,  any cash,
         property  or  securities  paid  in  respect  of  such  redemption.   An
         adjustment made pursuant to this subsection (i) shall become  effective
         immediately  after  the  record  date  in the  case  of a  dividend  or
         distribution and shall become effective immediately after the effective
         date in the case of a subdivision or combination.

                           (ii)  Whenever  the  Conversion  Price is adjusted as
         provided above, Borrower shall compute the adjusted Conversion Price in
         accordance  herewith  and  mail to  Holder a  notice  stating  that the
         Conversion  Price has been  adjusted  and  setting  forth the  adjusted
         Conversion Price.

                           (iii) In the event  that at any time,  as a result of
         any  adjustment  made  pursuant to this  Section,  Holder  shall become
         entitled to receive any shares of Borrower  other than shares of Common
         Stock or to  receive  any other  securities,  the  number of such other
         shares or securities so receivable  upon  conversion of this Note shall
         be subject to adjustment  from time to time in a manner and on terms as
         nearly  equivalent as practicable to the provisions  contained in these
         provisions with respect to Common Stock.

                  (d) No  Fractional  Shares.  No  fractional  shares  or  scrip
representing  fractional  shares of Common Stock shall be issued upon conversion
of this Note.  All  calculations  of the number of shares of Common  Stock to be
issued upon conversion of this Note shall be rounded to the nearest whole share.

                  (e) Reclassification, Consolidation, Merger or Sale of Assets.
In case of any  reclassification  of Common Stock, any consolidation of Borrower
with, or merger of Borrower into, any other person, any merger of another person
into   Borrower   (other   than  a  merger   which   does  not   result  in  any
reclassification,  conversion, exchange or cancellation of outstanding shares of
Common Stock of Borrower),  any sale or transfer of all or substantially  all of
the assets of Borrower or any compulsory share exchange  pursuant to which share
exchange  the Common  Stock is converted  into other  securities,  cash or other
property,  then  lawful  provision  shall  be made as part of the  terms of such
transaction  whereby Holder shall have the right  thereafter,  during the period
this Note shall be  convertible  hereunder,  to convert  this Note only into the
kind and amount of  securities,  cash and other  property  receivable  upon such
reclassification,  consolidation,  merger, sale, transfer or share exchange by a
holder of the number of shares of Common Stock of Borrower  into which this Note
might  have  been  converted   immediately   prior  to  such   reclassification,
consolidation,  merger, sale, transfer or share exchange assuming such holder of
Common Stock of Borrower (i) is not a person with which Borrower consolidated or
into which Borrower merged or which merged into Borrower,  to which such sale or
transfer  was  made or a party  to  such  share  exchange,  as the  case  may be
("constituent  person"), or an affiliate of a constituent person and (ii) failed
to  exercise  his  rights  of  election,  if any,  as to the kind or  amount  of
securities,  cash and other  property  receivable  upon  such  reclassification,
consolidation,  merger,  sale,  transfer or share exchange (provided that if the
kind or  amount of  securities,  cash and other  property  receivable  upon such
reclassification, consolidation, merger, sale, transfer or share exchange is not
the same for each share of Common Stock of Borrower  held  immediately  prior to
such consolidation,  merger, sale or transfer by other than a constituent person
or an  affiliate  thereof and in respect of which such rights of election  shall
not have been  exercised  ("non-electing  share"),  then the kind and  amount of
securities,  cash and other  property  receivable  upon  such  reclassification,
consolidation,  merger,  sale,  transfer or share exchange by each  non-electing
share  shall be deemed to be the kind and  amount so  receivable  per share by a
plurality  of the  non-electing  shares).  Borrower,  the person  formed by such
consolidation  or resulting  from such merger or which  acquires  such assets or
which acquires  Borrower's  shares, as the case may be, shall make provisions in
its certificate or articles of  incorporation or other  constituent  document to
establish such right.  Such  certificate or articles of  incorporation  or other
constituent  document shall provide for adjustments which, for events subsequent
to the effective date of such  certificate or articles of incorporation or other
constituent document, shall be as nearly equivalent as may be practicable to the
adjustments  provided for herein.  The above provisions shall similarly apply to
successive reclassifications, consolidations, mergers, sales, transfers or share
exchanges.

<PAGE>

                  (f) Reservation of Shares; Transfer Taxes; Etc. Borrower shall
at all times  reserve and keep  available,  out of its  authorized  and unissued
stock,  solely for the purpose of effecting the  conversion  of this Note,  such
number of shares of its Common  Stock and other  securities  free of  preemptive
rights as shall from time to time be sufficient to effect the conversion of this
Note. Borrower shall from time to time, in accordance with the laws of the State
of Utah, increase the authorized number of shares of Common Stock if at any time
the number of shares of Common Stock not outstanding  shall not be sufficient to
permit  the  conversion  of this Note.  Borrower  shall pay any and all issue or
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock or other securities upon conversion of this Note by Holder.

     2.  Defined  Terms.  As used in this  Note,  the  following  terms have the
respective meanings set

forth below:

          (a) "Common  Stock"  shall mean the common  stock of Borrower  and any
     capital  stock into which such common stock shall have been changed and any
     other stock resulting from any  reclassification of such stock which is not
     preferred  as to  dividends  or assets  over any other class of stock which
     shall be in effect from time to time.

          (b) "Conversion  Price" shall mean,  subject to adjustment as provided
     in Section 1(c) hereof, $3.08.

     3.  Prepayments.  Borrower shall have the right to prepay the principal and

     4.  Default Remedies.

                  (a)  Borrower  shall be in  default  under  this Note upon the
         happening of any condition or event set forth below (each, an "Event of
         Default"):

          (i)  Borrower shall fail to pay the principal and interest due on this

               accordance  with the terms hereof and Borrower fails to make such
               payment  within  twenty  (20)  days of the  date  which  Borrower
               receives written notice from the Holder that any such payment has
               not been received by Holder;

          (ii) default by  Borrower  in the  punctual  performance  of any other
               obligation,  covenant,  term or provision contained in this Note,
               and such default shall  continue  unremedied  for a period of ten
               (10) days or more  following  written notice of default by Holder
               to Borrower;

          (iii)The  commencement  of any  proceeding  under  any  bankruptcy  or
               insolvency laws by or against Borrower which results in the entry
               of an order for relief which remains undismissed, undischarged or
               unbonded for a period of 60 days or more.

                  (b) The entire unpaid  principal  balance of this Note and all
         accrued  interest  thereon shall  immediately be due and payable at the
         option of the holder  hereof upon the  occurrence of any one or more of
         the Events of Default and at any time thereafter.

         5. Cumulative  Rights.  No delay on the part of the holder of this Note
in the  exercise  of any  power or right  under  this  Note or under  any  other
instrument executed pursuant hereto shall operate as a waiver thereof, nor shall
a single or partial  exercise  of any power or right  preclude  other or further
exercise thereof or the exercise of any other power or right.

<PAGE>

         6. Waiver.  Borrower  waives demand,  presentment,  protest,  notice of
dishonor,  notice of nonpayment,  notice of intention to accelerate or notice of
acceleration  (other  than  notices of default  required  pursuant  to  Sections
4(a)(i) and (ii)),  notice of protest and any and all lack of diligence or delay
in  collection  or the filing of suit hereon  which may occur,  and agree to all
extensions and partial payments, before or after maturity,  without prejudice to
the holder hereof.

         7.  Attorneys' Fees and Costs. In the event that this Note is collected
in  whole or in part  through  suit,  arbitration,  mediation,  or  other  legal
proceeding of any nature,  then and in any such case there shall be added to the
unpaid  principal amount hereof all reasonable costs and expenses of collection,
including, without limitation, reasonable attorney's fees.

         8.  Governing  Law.  This Note shall be  governed by and  construed  in
accordance  with the internal laws of the State of Texas,  without giving effect
to  conflicts  of law  provision  or rule  (whether of the State of Texas or any
other  jurisdiction)  that would  result in the  application  of the laws of any
jurisdiction other than the State of Texas.

         9.       Headings.  The  headings  of the  sections of this Note are
inserted  for  convenience  only and shall not be deemed to constitute a part
hereof.

         10. Usury. All agreements between Borrower and the holder of this Note,
whether now  existing or  hereafter  arising  and whether  written or oral,  are
expressly  limited so that in no  contingency  or event  whatsoever,  whether by
acceleration  of the maturity of this Note or otherwise,  shall the amount paid,
or agreed to be paid, to the holder hereof for the use, forbearance or detention
of the money to be loaned  hereunder  or  otherwise,  exceed the maximum  amount
permissible  under  applicable  law.  If  from  any   circumstances   whatsoever
fulfillment of any provision of this Note or of any other  document  evidencing,
securing  or  pertaining  to the  indebtedness  evidenced  hereby,  at the  time
performance of such provision shall be due, shall involve exceeding the limit of
validity  prescribed  by law,  then ipso facto,  the  obligation to be fulfilled
shall  be  reduced  to the  limit  of  such  validity,  and  if  from  any  such
circumstances  the holder of this Note shall ever  receive  anything of value as
interest  or deemed  interest  by  applicable  law under  this Note or any other
document evidencing, securing or pertaining to the indebtedness evidenced hereby
or otherwise an amount that would  exceed the highest  lawful rate,  such amount
that  would be  excessive  interest  shall be applied  to the  reduction  of the
principal  amount owing under this Note or on account of any other  indebtedness
of Borrower to the holder hereof  relating to this Note,  and not to the payment
of  interest,  or if such  excessive  interest  exceeds  the  unpaid  balance of
principal  of this  Note and  such  other  indebtedness,  such  excess  shall be
refunded to Borrower. In determining whether or not the interest paid or payable
with respect to any  indebtedness  of Borrower to the holder  hereof,  under any
specific  contingency,  exceeds the highest lawful rate, Borrower and the holder
hereof  shall,   to  the  maximum  extent   permitted  by  applicable  law,  (a)
characterize any nonprincipal  payment as an expense, fee or premium rather than
as  interest,  (b)  amortize,  prorate,  allocate and spread the total amount of
interest  throughout the full term of such  indebtedness so that the actual rate
of  interest  on account of such  indebtedness  is uniform  throughout  the term
thereof, and/or (c) allocate interest between portions of such indebtedness,  to
the end that no such  portion  shall bear  interest at a rate  greater than that
permitted by law. The terms and provisions of this  paragraph  shall control and
supersede every other conflicting  provision of all agreements  between Borrower
and the holder hereof.

     11.  Successors  and  Assigns.  This Note may not be sold,  transferred  or
otherwise  assigned by Holder  without the prior  written  consent of  Borrower.
Borrower's  obligations  under  this Note may not be  transferred  or  otherwise
assigned by Borrower without the prior written consent of Holder.

     12. Severability.  In the event any one or more of the provisions contained
in  this  Note  shall  for  any  reason  be  held  to  be  invalid,  illegal  or
unenforceable in any respect,  such invalidity,  illegality or  unenforceability
shall not affect any other provision hereof, and this Note shall be construed as
if such invalid,  illegal or  unenforceable  provision had never been  contained
herein.

of relocating, including without

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    limitation,
(i) travel, transportation, meals, temporary lodging and similar related moving
expenses, and (ii) closing costs, real estate commissions, attorney’s fees and
other similar costs reasonably incurred by Executive in the
relocation.  All expenses subject to income tax shall be grossed up
such that the state and federal tax effect to Executive is zero.  The
Company and the Executive agree to work in good faith to minimize the potential
gross-up to the extent consistent with applicable laws and
regulations.  Executive shall not be required to relocate to the
vicinity of the Company’s Jacksonville headquarters until his home in Chicago,
Illinois is sold. If the Board in writing directs the Executive to move his
primary residence in accordance with the foregoing provisions, the Executive
covenants and agrees to use his best efforts to sell such primary
residence.

     

    (c) The
Executive shall devote his full business time, attention, skills and energies to
the performance of his duties hereunder and to the promotion of the business of
the Company.  The Executive may not, during the Employment Period, be
employed or engaged in any other business activity, whether or not such activity
is pursued for gain, profit or other pecuniary advantage, which would not allow
him to contribute his full business time, attention, skills and energies to the
performance of his duties hereunder and to the promotion of the business of the
Company without the written consent of the Chairman of the
Company.  Nothing in this paragraph will be construed as preventing
the Executive from investing his personal assets in businesses which do not
compete with the Company and engaging in not-for-profit and civic activities
that do not interfere with the Executive’s duties hereunder.

     

    3. COMPENSATION.

     

    (a) Salary.  For
services rendered by the Executive hereunder during the Employment Period, the
Company shall pay Executive a base salary (the “Salary”) at the annual gross
rate of Two Hundred Fifty Thousand Dollars ($250,000) in accordance with the
Company’s ordinary payroll practices.  An employment review will take
place on an annual basis.  Any increases in the Salary shall be
determined on an annual basis by the Board in its sole discretion.

     

    (b) Signing
Bonus.  Within ten (10) days after the beginning of the
Employment Period, the Company shall pay the Executive a signing bonus of Twenty
Five Thousand Dollars ($25,000) in accordance with its ordinary payroll
practices.

     

    (c) Bonus.  During
the Employment Period, the Executive will be eligible to receive a cash bonus
(the “Bonus”) based on
an EBITDA target for the Company (30% of total Bonus), a revenue target for the
Company (30% of total Bonus) and other management objectives (40% of total
Bonus) (the (“Targets”)).  Within
sixty (60) days after the beginning of each fiscal year beginning with the
fiscal year ending December 31, 2007, the Board shall establish the Targets such
that (i) upon achieving the first threshold for all of the Targets, the Company
will pay the Executive a Bonus equal to thirty percent (30%) of the Salary; (ii)
upon achieving the second threshold (which includes meeting the annual plan for
all of the Targets) for all of the Targets, the Company will pay the Executive a
Bonus equal to sixty percent (60%) of the Salary; and (iii) upon achieving the
third threshold for all of the Targets, the Company will pay the Executive a
Bonus equal to eighty percent (80%) of the Salary.  All Targets and
Bonus threshold levels will be determined by the Board in good faith after
consultation with the Executive.  Additional Bonuses, if any, shall be
determined on an annual basis or otherwise as determined by the Board in its
sole discretion.  All Bonuses are subject to the Company’s ordinary
payroll practices and payable within sixty (60) days after the end of each
fiscal year.  Notwithstanding the foregoing, for the fourth quarter of
2006, the Company shall pay the Executive a Bonus equal to (i) no less than
Thirty Seven Thousand Five Hundred Dollars

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    ($37,500),
multiplied by (ii) the quotient of the number of working days the Executive is
employed by the Company in the fourth quarter of 2006 divided by the number of
working days in the fourth quarter of 2006.

     

    (d) Stock
Options.  Executive shall be entitled to receive, as soon as
practicable following October 9, 2006, nonqualified stock options in accordance
with the terms of the a21 stock incentive plan (the “Plan”) and the standard stock
option agreement thereunder; provided, however, that such options shall provide
the Executive with the right to purchase 500,000 shares of a21 common stock (the
“Stock”) at a purchase
price equal to the greater of (i) the mean of the highest and lowest bid prices
per share of the Stock on October 9, 2006, and (ii) the average closing price of
the Stock for the ten trading days prior to and including October 9,
2006.  Options to purchase 62,500 shares of Stock shall vest on the
six month anniversary of October 9, 2006 and the remainder shall vest in
forty-two (42) equal monthly shares on the first day of each month thereafter
such that all of such options will be vested by the forty-eighth (48th) month
anniversary of October 9, 2006.  The options shall be exercisable for
a period of five (5) years from the October 9, 2006.  All unvested
options shall immediately vest (i) upon a change in control, as defined in the
stock option agreement entered into pursuant to the Plan (a “Change in Control”), (ii) in
the event that the Company and the Executive negotiating in good faith are
unable to reach an agreement, by no later than the three year anniversary
of  October 9, 2006, regarding an extension of this Agreement or a new
employment agreement and this Agreement is not earlier terminated pursuant to
Sections 4(b)-(f) of this Agreement, or (iii) upon the Executive’s death or
Disability.

     

    (e) Restricted
Stock.  Executive shall be entitled to receive, as soon as
practicable following October 9, 2006, 500,000 shares of restricted Stock in
accordance with a restricted stock agreement provided by the
Company.  62,500 shares of such restricted Stock shall vest on the six
month anniversary of October 9, 2006 and the remainder shall vest in forty-two
(42) equal monthly shares on the first day of each month thereafter such that
all of such shares shall be vested by the forty-eighth (48th) month
anniversary of October 9, 2006.  All unvested shares of restricted
Stock shall immediately vest (i) upon a change in control, as defined in the
restricted stock agreement, (ii) in the event that the Company and the Executive
negotiating in good faith are unable to reach an agreement, by no later than the
three year anniversary  of October 9, 2006, regarding an extension of
this Agreement or a new employment agreement and this Agreement is not earlier
terminated pursuant to Sections 4(b)-(f) of this Agreement, or (iii) upon the
Executive’s death or Disability.

     

    (f) Benefits.  During
the Employment Period, the Company shall pay One Thousand Four Hundred Dollars
($1,400) per month (the “Benefit Amount”) of medical,
dental, life insurance, pension or other employee benefits for the Executive,
each as determined by the Executive, whether the Executive elects to use the
benefit plans provided by the Company from time to time or
otherwise.  The Company will increase the Benefit Amount by 5% in
January of each year beginning with January 2008.  The Company will
permit the Executive to make contributions to the Company’s 401(k) plan, subject
to the terms and conditions of such plan.  The Executive is entitled
to such amount of paid vacation as is in the best interests of the Company after
coordination with the Chairman of the Board, which in no event shall be less
than three (3) calendar weeks.

     

    (g) Expense
Reimbursement. The Executive is authorized to incur reasonable expenses
related to the performance of his duties under this Agreement in accordance with
budgets and guidelines established by the Company from time to time or otherwise
approved by the Board.  The Company shall promptly reimburse the
Executive for all

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    such
documented expenses in accordance with its expense reimbursement policy in
effect from time to time.

     

    (h) Residence/Moving
Expenses.  From October 9, 2006 until the date that the
Executive moves his primary residence to the vicinity of the Company’s then
headquarters in accordance with Section 2(a) of this Agreement, the Company
shall make available to the Executive a reasonably appropriate apartment in the
vicinity of the Company’s headquarters.  The Company agrees that it
will reimburse the Executive’s reasonable moving expenses to move from his
current home to a location referenced in Section 2(b) of this Agreement upon
submission of such reasonable evidence thereof as the Company shall
request.  The Executive covenants and agrees to minimize the aggregate
amount of the moving expenses to the extent reasonably practicable.

     

    (i) Special
Bonus.  If both a Change in Control and a greater than
$9,000,000 reduction in the amount of the Company’s outstanding promissory notes
occur after the Effective Date (collectively, the “Conditions”), then the Company
shall pay the Executive a special bonus (the “Special
Bonus”).  The Special Bonus shall be equal to the lesser of
(i)(a) 1.5% multiplied by the amount the Company’s outstanding promissory
notes are reduced below the amount of such notes in existence at the Effective
Date, plus (b) 1.5% multiplied by the amount of capital (whether in the form of
equity and/or debt) received by the Company within ninety (90) days after the
Effective Date, unless such capital is used to reduce the amount of the
Company’s outstanding promissory notes in existence at the Effective Date, and
(ii) One Hundred Twenty Five Thousand Dollars ($125,000).  The Company
shall pay the Special Bonus within ten (10) days after satisfaction of both of
the Conditions in accordance with its ordinary payroll practices.  The
Special Bonus shall only be paid once.  Debt forgiveness, conversion
or exchange of outstanding promissory notes into or for the Company’s equity
securities shall satisfy the Conditions.

     

    (j) Taxes.  All
payments and benefits provided to the Executive hereunder shall be reported as
taxable income to the extent required by law and shall be subject to applicable
income and payroll withholding taxes.

     

    4. TERM AND
TERMINATION.

     

    (a) The term

commence on October 9, 2006 and continue for thirty-six (36) months unless
terminated earlier in accordance with this Paragraph 4.

     

    (b) Termination Without
Cause.  Either party hereto may terminate this Agreement and

Executive’s resignation from all positions (including any directorships) with
the Company or its Affiliates (as defined below) and the execution and delivery
by the Executive of a separation agreement and general release, in a form
reasonably acceptable to the Company, of all claims related to his employment or
termination thereof through and including the date Executive signs such release,
pay to the Executive (i) any unpaid Salary accrued as of the date of
termination, (ii) Salary at the annual rate in effect on the date of termination
for a period of six (6) months (twelve (12) months if, following a Change in
Control, the Company terminates this Agreement or the Executive’s employment
without Cause after the Effective Date) in installments in accordance with the
Company’s ordinary payroll practices, (iii) a pro rata portion

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    of any
Bonus payable in respect of the fiscal year in which the date of termination
occurs, and (iv) reimbursement of any outstanding business expenses for which
Executive is entitled to be reimbursed in accordance with this Agreement up to
and including the date of termination.  The Executive shall not be
entitled to any further payments or benefits from the Company or any of its
Affiliates, except as required by any federal or state law requiring
continuation of benefits and except as may be provided in any other agreement
with the Company.

     

    (c) Termination for
Cause.  The Company may terminate this Agreement and the
Executive’s employment for Cause (as hereinafter defined) at any time, effective
immediately upon giving the Executive written notice of such
termination.  As used herein, the term “Cause” shall mean any of the
following events:

     

    (i) the
Executive’s conviction of or plea of guilty, nolo contendere, or no contest to a
misdemeanor involving moral turpitude or a felony which may result in a term of
imprisonment;

     

    (ii) the
Executive’s material breach of this Agreement or willful failure to carry out
the lawful directives of the Board consistent with Paragraph 2(a) hereof
(provided the Company has given the Employee advance written notice specifying
the nature of such breach or failure to carry out the lawful directives of the
Board and the Executive has not cured such breach within thirty (30) days of
having received such notice); or

     

    (iii) the
Executive’s (A) willful gross misconduct, including, without limitation,
dishonesty, fraud or theft, or (B) willful bad faith act or failure to act that
is in the sole discretion of the Board injurious to the business or reputation
of the Company.

     

    In the
event of termination for Cause, the Company shall pay to the Executive (i) any
unpaid Salary accrued as of the date of termination, (ii) an amount equal to
three months of the Salary, paid over a period of six (6) months in installments
in accordance with the Company’s ordinary payroll practices, and (iii)
reimbursement of any outstanding business expenses for which Executive is
entitled to be reimbursed in accordance with this Agreement up to and including
the date of termination.  The Executive shall not be entitled to any
further payments or benefits except as required by any federal or state law
requiring continuation of benefits and except as may be provided in any other
agreement with the Company.

     

    (d) Death.  If
the Executive dies during the Employment Period, this Agreement and the
Executive’s employment shall terminate as of the date of his
death.  The Company shall pay to the Executive’s estate any unpaid
Salary and the Executive’s estate shall not be entitled to any further payments
or benefits from the Company or any of its Affiliates except as required by any
federal or state law requiring continuation of benefits and except as may be
provided in any other agreement with the Company.

     

    (e) Disability.  If
the Executive is incapacitated by accident, sickness or otherwise so as to
render him mentally or physically incapable of performing the services required
of him under this Agreement (referred to herein as a “Disability”) for (i) a period
of ninety (90) consecutive days or (ii) for an aggregate of one hundred twenty
(120) business days during any twelve (12) month period, the Company may
terminate this Agreement and the Executive’s employment effective immediately
after the expiration of either of such periods, upon giving the Executive
written notice of such termination.  Notwithstanding the foregoing
provision, if it is determined by the Company that the Executive has a
“disability” as defined under the Americans with Disabilities Act, the
Executive’s employment shall not be terminated on the basis of such disability
unless it is first determined by the Company, after
consultation

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    with the
Executive, that there is no reasonable accommodation which would permit the
Executive to perform the essential functions of his position without imposing an
undue hardship on the Company.

     

    In the
event the Executive is determined to have a Disability hereunder and receives
payments under any disability plan maintained by the Company for its employees
or under any other arrangement maintained by the Company for the Executive or by
the Executive, such payments shall reduce and offset any Salary payable to the
Executive pursuant to Paragraph 3 hereof, to extent permitted under such plan or
arrangement.  In the event of termination pursuant to this
Subparagraph 4(e), the Company shall pay to the Executive any unpaid Salary
accrued as of the date of termination and the Executive shall not be entitled to
any further payments or benefits from the Company or any of its Affiliates
except as required by any federal or state law requiring continuation of
benefits and except as may be provided in any other agreement with the
Company.

     

    (f) Good
Reason.  The Executive may, upon thirty (30) days’ written
notice to the Company, terminate this Agreement and the Executive’s employment
for Good Reason (as hereinafter defined).  Upon a termination of
Executive’s employment for Good Reason, subject to Executive’s compliance with
Sections 5, 6 and 7 hereof, the Executive’s resignation from all positions
(including any directorships) with the Company or its Affiliates and the
execution and delivery by the Executive of a separation agreement and general
release, in a form reasonably acceptable to the Company, of all claims related
to his employment or termination thereof through and including the date
Executive signs such release, the Executive shall be entitled to the benefits
specified in Paragraph 4(b) of this Agreement (including Salary at the annual
rate in effect on the date of termination for a period of twelve (12) months if,
following a Change of Control, the Executive terminates this Agreement and the
Executive’s employment for Good Reason after the Effective Date).  As
used herein, the phrase “Good Reason” shall mean (i) the reduction of the
Executive’s title and/or responsibilities to below those of a senior executive
of the Company (except in connection with the termination of Executive’s
employment for Cause or Disability or as a result of the Executive’s death, or
temporarily as a result of the Executive’s illness or other absence), (ii) a
material breach of this Agreement by the Company; provided the Executive has
given the Company advance written notice specifying the nature of such reduction
or breach and a period of at least thirty (30) days to cure such reduction or
breach, (iii) the Company requires Executive to relocate his primary residence
more than one time during the Employment Period of this Agreement, (iv) any
reduction in Salary or Bonus opportunity, or (v) the failure by the Company to
grant the Stock options and restricted Stock under Sections 3(d) and (e) of this
Agreement within sixty (60) days after October 9, 2006.

     

    5. NON-SOLICITATION.

     

    (a) Non-Solicitation of
Employees and Consultants.  The Executive hereby agrees that
during the Employment Period and for a period equal to six (6) months, or twelve
(12) months if the Executive is entitled to Salary for such longer period of
time in accordance with the provisions of Paragraph 4(b) or 4(f) of this
Agreement, after the Employment Period (the “Survival Period”), he shall
not, directly or indirectly through any other individual, person or entity,
employ, solicit or induce any individual, who is or was at any time during the
last twelve (12) months of the Executive’s employment by the Company, an
employee or consultant of the Company, to terminate or refrain from renewing or
extending his or her employment or relationship with the Company, or to become
employed by or enter into a contractual relationship with the Executive or any
other individual, person or entity.  For the purposes of Paragraphs 5,
6 and 7 of this Agreement the term “Company” shall be deemed to
include the Company and each of its Affiliates.  For the purposes of
this Agreement, the term “Affiliate”

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    shall
mean, with respect to any person, any person directly or indirectly controlling,
controlled by, or under common control with, such other person at any time
during the period for which the determination of affiliation is being
made.

     

    (b) Non-Solicitation of
Suppliers or Vendors.  The Executive hereby agrees that during
the Employment Period and the Survival Period he may not, directly or indirectly
through any other individual, person or entity, solicit, persuade or induce any
individual, person or entity which is, or at any time during the Employment
Period was, a supplier of any product or service to the Company, or vendor of
the Company (whether as a distributor, agent, commission agent, employee or
otherwise), to terminate, reduce or refrain from renewing or extending his, her
or its contractual or other relationship with the Company.

     

    (c) Non-Solicitation of
Customers.  The Executive hereby agrees that during the
Employment Period and the Survival Period he may not, directly or indirectly
through any other individual, person or entity, solicit, persuade or induce any
individual, person or entity which is, or at any time during the Employment
Period was, a customer of the Company to terminate, reduce or refrain from
renewing or extending its contractual or other relationship with the Company in
regard to the purchase of products or services manufactured, marketed or sold by
the Company, or to become a customer of or enter into any contractual or other
relationship with the Executive or any other individual, person or entity in
regard to the purchase of products or services similar or identical to those
manufactured, marketed or sold by the Company.

     

    6. CONFIDENTIALITY.  The
Executive agrees that, during the Employment Period and thereafter, the
Executive shall not divulge to anyone, other than as necessary in the
performance of his duties hereunder or as required by law or legal process,
confidential information of the Company, its Affiliates or its customers,
including, without limitation, know-how, trade secrets, customer lists, costs,
profits or margin information, markets, sales, pricing policies, operational
methods, plans for future development, data, drawings, samples, processes or
products and other information disclosed to the Executive or known by him as a
result of or through his employment by the Company, which is not generally known
in the businesses in which the Company is engaged and which relates directly or
indirectly to the Company’s products or services or which is directly or
indirectly useful in any aspect of the Company’s business.  In the
event the Company is bound by a confidentiality agreement with a customer,
supplier or other party regarding the confidential information of such customer,
supplier or other party, which provides greater protection than specified above
in this Paragraph 6, the provisions of such other confidentiality agreement
shall be binding upon the Executive and shall not be superseded by this
Paragraph 6.  Upon the termination of the Executive’s employment
hereunder or at any other time upon the Company’s request, the Executive shall
deliver forthwith to the Company all memoranda, notes, records, reports,
computer disks and other documents (including all copies thereof) containing
such confidential information.

     

    7. NON-COMPETITION.  The
Executive acknowledges that he has substantial experience and expertise, that in
the course of providing services to the Company he will become familiar with the
Company’s trade secrets and with other confidential information concerning the
Company and that Executive’s services have been and will be of special, unique
and extraordinary value to the Company.  The Executive hereby agrees
that during the Employment Period and the Survival Period, the Executive shall
not, directly or indirectly, anywhere in the entire United States and Europe,
own, manage, operate, control or participate in the ownership, management,
operation or control of, or be connected as an officer, employee, partner,
director, independent contractor or in any other capacity with, or have any
financial interest in, or aid or assist anyone else in the manufacture, sale or
representation of products or the provision of services identical or similar to
the products and services manufactured, sold, represented or provided by the
Company, and which products or services

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    are
marketed to the same customer base as the products or services offered by the
Company, at any time during the Employment Period or the Survival Period, or
which are included in any business plans of the Company in existence and under
consideration during the Employment Period and of which Executive was
aware.

     

    8. REASONABLE
RESTRICTIONS.  The parties acknowledge that (i) the type and
periods of restriction imposed in this Agreement are fair and reasonable and are
reasonably required in order to protect and maintain the proprietary interests
of the Company described above, other legitimate business interests of Company
and the goodwill associated with the business of the Company, and (ii) that the
time, scope, geographic area and other provisions of this Agreement have been
specifically negotiated by sophisticated commercial parties, represented by
legal counsel, and are given as an integral part of the transactions
contemplated by this Agreement.  Accordingly, you agree not to contest
the validity or enforceability of any provision of this Agreement and agree that
if any court should hold any provision of this Agreement to be unenforceable,
the remaining provisions will nonetheless be enforceable according to their
terms.

     

    9. REMEDIES.  The
Executive acknowledges and agrees that the Company’s remedy at law for a breach
or threatened breach of any of the provisions of Paragraphs 5, 6 or 7 of this
Agreement would be inadequate and, in recognition of that fact, in the event of
a breach or threatened breach by the Executive of any of the provisions of
Paragraphs 5, 6 or 7 of this Agreement, it is agreed that in addition to its
remedy at law, the Company shall be entitled to appropriate equitable relief in
the form of specific performance, preliminary or permanent injunction, temporary
restraining order or any other appropriate equitable remedy which may then be
available.  Notwithstanding any provision of this Agreement to the
contrary, it is expressly understood and agreed that, although the Executive and
the Company consider the restrictions contained in Paragraphs 5, 6 and 7 to be
reasonable for the purpose of preserving the Company’s goodwill and other
proprietary rights, if a final judicial determination is made by a court having
jurisdiction that the time and scope of the restrictions in such Paragraphs is
an unreasonable or otherwise unenforceable restriction against the Executive,
the provisions of such Paragraphs shall not be rendered void but shall be deemed
amended to apply as to the maximum time and scope permitted and to such other
extent as the court may determine to be reasonable.  Notwithstanding
the foregoing, in the event the Company breaches any of its payment obligations
under Section 4 of this Agreement (provided the Executive has given the Company
written notice specifying the nature of such breach and a period of at least
thirty (30) days to cure such breach), Executives obligations under Sections 5
and 7 of this Agreement shall terminate and be of no further force and effect
after the expiration of such thirty (30) day period if the Company has not cured
such breach.

     

    10. SECTION
409A COMPLIANCE.  All payments of “nonqualified deferred
compensation” (within the meaning of Section 409A of the Internal Revenue Code
of 1986, as amended (“Code”)) are intended to comply
with the requirements of Code Section 409A, and shall be interpreted in
accordance therewith.  Neither party individually or in combination
may accelerate any such deferred payment, except in compliance with Code Section
409A, and no amount shall be paid prior to the earliest date on which it is
permitted to be paid under Code Section 409A.  In the event that the
Executive is determined to be a “key employee” (as defined in Code Section
416(i) (without regard to paragraph (5) thereof)) of the Company at a time when
its stock is deemed to be publicly traded on an established securities market,
payments determined to be “nonqualified deferred compensation” payable following
termination of employment shall be made no earlier than the earlier of (i) the
last day of the sixth (6th) complete calendar month following such termination
of employment, or (ii) the Executive’s death, consistent with the provisions of
Code Section 409A.  Unless otherwise expressly provided, any payment
of compensation by Company to the Executive, whether pursuant to
this

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    Agreement
or otherwise, shall be made within two and one-half months (21⁄2 months) after the
end of the calendar year in which the Executive’s right to such payment vests
(i.e., is not subject
to a substantial risk of forfeiture for purposes of Code Section
409A).  Notwithstanding anything herein to the contrary, no amendment
may be made to this Agreement if it would cause the Agreement or any payment
