PORTFOLIO LEASEHOLD ACQUISITION AGREEMENT

        This PORTFOLIO  LEASEHOLD  ACQUISITION  AGREEMENT (the  "Agreement")  is
entered  into  this  10th day of July  2008  (this  "Agreement"),  by and  among
Implantable  Vision,  Inc., a Utah corporation  (the  "Company"),  Lariat Energy
Corporation,  a Nevada corporation "Lariat",  Pilgrim Petroleum  Corporation,  a
Delaware corporation  ("Pilgrim"),  and American Petroleum Corporation,  a Texas
corporation ("American" and, together with Pilgrim and Lariat, the "Seller").

                                    RECITALS

          WHEREAS,  the Company desires to purchase  certain  resource  property
assets of the Seller and the Seller  desires to sell such  assets to the Company
on the terms and conditions set forth in this Agreement;

         WHEREAS,  Seller owns an undivided one hundred  percent (100%) interest
(the "Subject Interest") in the oil and gas leases described on Exhibit A hereto
(the "Leases") and in the lands  described  therein (the "Lands") and desires to
sell its Subject Interest in the Leases;

         WHEREAS,  Seller  believes  the current  value of these assets is sixty
million  dollars  ($60,000,000),  based  upon  the  Resource  Evaluation  Report
prepared  according  to  National  Instrument  51-101 by  Gustavson  Associates,
Independent Qualified Reserves Evaluators, dated September 15, 2006. This report
reflected a Net Present  Value of Future Net  Revenues  (10%  discount  rate) of
$52,050,000  at the time of the  report.  Based upon the  increase in the market
value of the  underlying  price of a barrel of oil and billion cubic feet of gas
since this report, Seller believes that the value of the assets has increased to
$60,000,000.  However,  Seller can offer no assurances as to the increase in the
value of the assets;

         WHEREAS, American has the right to operate all oil and gas drilling and
other  activities  on  the  Leases  (the  "Operating   Rights")  under  Railroad
Commission of Texas; and

         WHEREAS,  Seller  has agreed  hereby to sell,  assign and convey to the
Company  and the Company  has agreed  hereby to purchase  and accept the Subject
Interest in the Leases subject to the terms and conditions of this Agreement.

          NOW,  THEREFORE,  in  consideration  of the  premises  and the  mutual
promises herein made, and in consideration of the  representations,  warranties,
and covenants  herein  contained and for other good and valuable  consideration,
the  receipt  and  sufficiency  of which are hereby  acknowledged,  the  parties
hereto, intending to be legally bound, agree as follows:

         third party,  but not later than twenty (20) days prior to the date any
         answer or responsive pleading is due, and with respect to other matters
         for which the Indemnified Party may seek  indemnification,  give prompt
         written notice to the  Indemnifying  Party of any liability which might
         give rise to a claim for indemnity; provided, however, that any failure
         to give such notice will not waive any rights of the Indemnified  Party
         except  to  the  extent  the  rights  of  the  Indemnifying  Party  are
         materially prejudiced.

                  (ii) The  Indemnifying  Party  shall  have the  right,  at its
         election,  to take over the  defense  or  settlement  of such  claim by
         giving  written notice to the  Indemnified  Party at least fifteen (15)
         days prior to the time when an answer or other  responsive  pleading or
         notice with respect  thereto is  required.  If the  Indemnifying  Party
         makes such  election,  it may conduct the defense of such claim through
         counsel of its choosing (subject to the Indemnified Party's approval of
         such counsel, which approval shall not be unreasonably withheld), shall
         be solely  responsible  for the  expenses of such  defense and shall be
         bound by the results of its  defense or  settlement  of the claim.  The
         Indemnifying Party shall not settle any such claim without prior notice
         to and consultation with the Indemnified  Party, and no such settlement
         involving any equitable relief or which might have an adverse effect on
         the  Indemnified  Party may be agreed to without the written consent of
         the  Indemnified   Party  (which  consent  shall  not  be  unreasonably
         withheld).  So long as the Indemnifying Party is diligently  contesting
         any such claim in good faith,  the Indemnified  Party may pay or settle
         such claim only at its own expense and the Indemnifying  Party will not
         be  responsible   for  the  fees  of  separate  legal  counsel  to  the
         Indemnified Party, unless the named parties to any

<PAGE>

         proceeding  include both parties and  representation of both parties by
         the same counsel would be inappropriate. If the Indemnifying Party does
         not make such  election,  or having made such election does not, in the
         reasonable  opinion of the  Indemnified  Party  proceed  diligently  to
         defend such claim, then the Indemnified Party may (after written notice
         to the Indemnifying  Party), at the expense of the Indemnifying  Party,
         elect to take over the  defense of and  proceed to handle such claim in
         its discretion and the Indemnifying Party shall be bound by any defense
         or settlement  that the  Indemnified  Party may make in good faith with
         respect to such claim. In connection therewith,  the Indemnifying Party
         will fully cooperate with the Indemnified  Party should the Indemnified
         Party elect to take over the defense of any such claim.

                  (iii) The parties  agree to cooperate in defending  such third
         party claims and the Indemnified  Party shall provide such  cooperation
         and  such  access  to  its  books,   records  and   properties  as  the
         Indemnifying  Party shall reasonably request with respect to any matter
         for which  indemnification is sought hereunder;  and the parties hereto
         agree to  cooperate  with each  other in order to ensure the proper and
         adequate defense thereof.

                  (iv)  With  regard  to  claims  of  third  parties  for  which
         indemnification is payable  hereunder,  such  indemnification  shall be
         paid by the  Indemnifying  Party upon the  earlier to occur of: (i) the
         entry of a judgment against the Indemnified Party and the expiration of
         any applicable appeal period, or if earlier, five (5) days prior to the
         date that the judgment  creditor has the right to execute the judgment;
         (ii) the entry of an unappeasable  judgment or final appellate decision
         against the  Indemnified  Party;  or (iii) a  settlement  of the claim.
         Notwithstanding the foregoing,  provided that there is no dispute as to
         the  applicability  of  indemnification,  the  reasonable  expenses  of
         counsel to the Indemnified Party shall be reimbursed on a current basis
         by the  Indemnifying  Party if such  expenses  are a  liability  of the
         Indemnifying   Party.   With   regard   to  other   claims   for  which
         indemnification is payable  hereunder,  such  indemnification  shall be
         paid promptly by the Indemnifying  Party upon demand by the Indemnified
         Party.

Company  or  Seller  if the  Exchange  has not  been or is  incapable  of  being

misrepresentation,  which may be asserted after the expiration of the applicable
survival period) and only if damages  resulting from such claim(s) exceed in the
aggregate  $25,000,  in which event  liability shall be for the entire amount of

THIS  CONVERTIBLE  PROMISSORY NOTE HAS NOT BEEN REGISTERED  UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR REGISTERED OR QUALIFIED UNDER
ANY STATE  SECURITIES  LAWS. THIS  CONVERTIBLE  PROMISSORY NOTE MAY NOT BE SOLD,
OFFERED  FOR  SALE,  PLEDGED  OR  HYPOTHECATED  WITHOUT  REGISTRATION  UNDER THE
SECURITIES ACT OR  REGISTRATION  OR  QUALIFICATION  UNDER SUCH STATE  SECURITIES
LAWS,  UNLESS THE PROPOSED  TRANSACTION  DOES NOT REQUIRE SUCH  REGISTRATION  OR

                           CONVERTIBLE PROMISSORY NOTE

$7,000,000.00              Dallas, Texas                     July ___, 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
__, 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.

<PAGE>

                  (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:

                           (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 any interest  outstanding under  this  Note in full or in part at
any time and from  time to time.  Any  prepayment  shall be  applied  first
against any accrued interest and then against principal.

         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 Note on the date which the same becomes due
                         and  payable in  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.

         13.  Notices.  All  notices  of  communication  required  or  permitted
hereunder  shall be in writing  and may be given by (a)  depositing  the same in
United States mail,  addressed to the party to be notified,  postage prepaid and
registered or certified with return receipt request,  (b) delivering the same in
person or by  overnight  express  to an  officer  or agent of such party or, (c)
telecopying the same with electronic confirmation of receipt:

                           CONVERTIBLE PROMISSORY NOTE

$3,000,000.00                Dallas, Texas                 July ___, 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  American  Petroleum  Corporation,  a  Texas  corporation,,   and  its
successors and permitted assigns ("Holder"),  the principal sum of Three Million
Dollars  ($3,000,000.00),  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
__, 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.

2.       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.

<PAGE>

     (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:

                           (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 any interest  outstanding under  this  Note in full or in part at
any time and from  time to time.  Any  prepayment  shall be  applied  first
against any accrued interest and then against principal.

         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"):

                    (iv) Borrower  shall fail to pay the  principal and interest
                         due on this Note on the date which the same becomes due
                         and  payable in  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;

                    (v)  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;

                    (vi) 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.

         13.  Notices.  All  notices  of  communication  required  or  permitted
hereunder  shall be in writing  and may be given by (a)  depositing  the same in
United States mail,  addressed to the party to be notified,  postage prepaid and
registered or certified with return receipt request,  (b) delivering the same in
person or by  overnight  express  to an  officer  or agent of such party or, (c)

                              Financial Statements

         The Company  plans to file an Amendment  No. 1 to its Annual  Report on
Form  10-KSB for the fiscal  year  ended  July 31,  2007 to amend the  financial
statements  included  therein to reflect the  removal of amounts  (approximately
$90,909) that were erroneously recorded as accumulated  depreciation relating to
the  amortization of the phakic  refractive lens that the Company  acquired from
CIBA Vision AG in June 2006. The  amortization of this asset is also erroneously
reflected in the Company's  Quarterly  Reports for the periods ended January 31,
2008 ($120,321), October 31, 2007 ($105,615) and April 30, 2007 ($14,706).American Note

                           CONVERTIBLE PROMISSORY NOTE

$3,000,000.00                     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  American  Petroleum  Corporation,  a  Texas  corporation,,   and  its
successors and permitted assigns ("Holder"),  the principal sum of Three Million
Dollars  ($3,000,000.00),  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

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
any interest outstanding under this Note in full or in part at any time and from
time to time. Any prepayment shall be applied first against any accrued interest
and then against principal.

         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 Note
          on the date which the same becomes due and payable in 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.
