CONVERTIBLE PROMISSORY NOTE

$2,000,000                     Las Vegas, Nevada              September 23, 2004

         Crystalix Group International, Inc., a Nevada corporation ("BORROWER"),
promises to pay to the order of CMKXTREME.COM ("LENDER") at 30 Princeville Lane,
Las Vegas, Nevada 89113, Two Million Dollars ($2,000,000),  with interest on the
unpaid principal balance.

         1.   Interest Rate.

              (a)  Interest  on the unpaid  principal  balance  hereunder  shall
accrue at the rate of ten percent (10%) per annum (the "INTEREST RATE") from the
date hereof. Default interest shall be paid in accordance with Section 6.

              (b) The  Interest  Rate  shall be  calculated  on the basis of the
unpaid principal  balance hereunder and the actual number of days elapsed over a
365-day year.  Notwithstanding  anything contained in this Note to the contrary,
if  collection  from Borrower of interest at the Interest Rate would be contrary
to  applicable  laws,  then the Interest  Rate in effect on any day shall be the
highest interest rate which may be collected from Borrower under applicable laws
on such day.

         2.   Payment Schedule.

              (a)  Commencing on November 1, 2004,  and  continuing on the first
day of each month  thereafter,  Borrower  shall make a principal  payment in the
amount  of  $83,333,  with  all  accrued  and  unpaid  interest  on the  amounts
outstanding under this Note.

              (b) All outstanding principal and accrued unpaid interest shall be
due and payable on October 1, 2007 (the  "MATURITY  DATE"),  as such date may be
accelerated pursuant to Section 4.

         3.    Amounts  due  hereunder  shall  be  paid by Borrower to Lender as
               follows:

              (a)  Except  as  provided  below in  Section  3(b),  all  payments
(including  payment and  prepayments of principal of or other amounts in respect
of the Advances or fees or other amounts) required under this Note shall be made
by the  Borrower to the Lender in lawful  money of the United  States of America
and in immediately available funds.

              (b) From time to time,  Lender may  require  Borrower  to make any
payment of the Convertible Portion (as defined below) of Borrower's  obligations
under this Note in shares of Common Stock of Borrower  ("Common Shares") instead
of lawful money of the United  States of America and thereby  convert all or any
part of such  Convertible  Portion  into that  number of  Common  Shares,  as is
obtained by  dividing  the dollar  amount  that Lender  elects to convert by the
applicable Conversion Price (as defined below).

              (c)  Subject  to  adjustment  as  provided  in this  Section,  the
"CONVERSION  PRICE" shall be the lesser of (i) the average  closing price of the
Common  Shares for the five (5)  business  days  immediately  prior to  Lender's
delivery of notice of conversion, or (ii) $0.08. The

99999.9SBY\YOKENS\LAS\65107.3


"CONVERTIBLE  PORTION"  means (w) any payment of  principal,  interest,  and any
other amounts payable to Lender hereunder when due, (x) any prepayment  tendered
by Borrower  under Section 8 of this Note,  (y) all or any portion of the entire
amount of  Borrower's  obligations  under  this Note,  upon a sale of  fifty-one
percent (51%) or more of the  outstanding  Common Stock of Borrower or a sale of
all or substantially all of Borrower's assets, or (z) if an Event of Default (as
defined below) occurs, a portion of Borrower's  obligations  under this Note not
exceeding One Million Dollars  ($1,000,000);  PROVIDED,  HOWEVER,  that upon the
occurrence of a second Event of Default while the first Event of Default remains
uncured, the entire amount of principal,  interest and any other amounts payable
by Lender hereunder shall be the Convertible Portion.

              (d) Within ten (10) days after delivery to Borrower of a notice of
conversion with respect to that portion of the outstanding and unpaid  principal
or interest  that Lender  wishes to  convert,  Borrower  shall (i) denote in its
corporate records the ownership by Lender of the Common Shares so purchased, and
(ii)  unless  this Note has been fully  repaid or  converted  in full,  issue to
Lender a new Note,  in  identical  form hereto and duly  executed  by  Borrower,
representing the portion of the Debt that has not been converted or repaid.

              (e)  If   Borrower   shall  (i)  declare  a  dividend  or  make  a
distribution  payable  in  Common  Shares,  (ii)  subdivide  or  reclassify  its
outstanding  Common  Shares  into a greater  number of Common  Shares,  or (iii)
combine its  outstanding  Common Shares into a smaller  number of Common Shares,
the Conversion  Price in effect at the time of the record date for such dividend
or  distribution  or the effective  date of such  subdivision,  combination,  or
reclassification shall be proportionately reduced in the case of any increase in
the  number of  Common  Shares  outstanding,  and  increased  in the case of any
reduction in the number of Common  Shares  outstanding,  so that Lender shall be
entitled to receive the kind and amount of Common Shares which Lender would have
owned or have been entitled to receive had this Note been  converted into Common
Shares  immediately  prior to such time and had such Common Shares received such
dividend or other distribution or participated in such subdivision, combination,
or  reclassification.  Such adjustment  shall be effective as of the record date
for such dividend or  distribution  or the effective  date of such  combination,
subdivision  or  reclassification  and shall be made  successively  whenever any
event listed above shall occur.

              (f)  Whenever  the  Conversion  Price is  adjusted  as provided in
Section 3(d),  Borrower shall promptly  deliver to Lender written notice setting
forth the  Conversion  Price after such  adjustment  and  setting  forth a brief
statement of the facts requiring such adjustment and the computation thereof.

              (g) In the event of any  consolidation  or merger of Borrower with
or into any other  Person  (other  than a merger  which  does not  result in any
reclassification,  conversion,  exchange or cancellation  of outstanding  Common
Shares),  or in the event of any sale or transfer of all or substantially all of
the assets of Borrower or the reclassification of the Common Shares into another
form of capital stock of Borrower,  whether in whole or in part, this Note shall
thereafter be convertible,  in lieu of the Common Shares  otherwise  purchasable
and receivable  upon  conversion of this Note, into the kind and amount of stock
and other  securities and property or cash which Lender would have been entitled
to receive upon such consolidation,  merger,  sale, transfer or reclassification
if Lender had held the Common Shares  issuable upon the  conversion of this Note
immediately   prior  to  such   consolidation,   merger,   sale,   transfer   or
reclassification.

99999.9SBY\YOKENS\LAS\65107.3



The  provisions  of  this  Section  3  shall   similarly   apply  to  successive
reclassification  and  changes of Common  Shares of capital of  Borrower  and to
successive consolidations, mergers, sales, transfers or reclassifications.

              (h) Borrower shall at all times reserve and keep  available,  free
from  pre-emptive  rights,  out of its authorized but unissued  shares of common
stock,  solely for the purpose of issue upon  conversion  of this Note as herein
provided,  such  number of  Common  Shares as shall  then be  issuable  upon the
conversion of this Note.  Borrower  covenants that all Common Shares which shall
be so issuable shall,  upon issuance,  be duly and validly issued and fully paid
and  non-assessable.  Borrower  shall  from  time to time,  in  accordance  with
applicable  law,  increase the authorized  amount of its Common Shares if at any
time the authorized amount of its Common Shares remaining  unissued shall not be
sufficient to permit the conversion of all Notes at the time outstanding.

         4.    Upon  any  Event of  Default,  as such  term is  defined  in this
Section 5, Lender may accelerate the loan evidenced by this Note and declare the
entire principal balance of the Note immediately due and payable, and shall have
the rights  provided  herein and by applicable law. The occurrence of any of the
following events shall constitute an "EVENT OF DEFAULT" under this Note:

              (a)  Borrower  fails to make any payment of interest or  principal
within five (5) days after the date when due under this Note.

              (b)  The  dissolution  of  Borrower,   whether   pursuant  to  any
applicable laws, or otherwise,  or the sale,  transfer or conveyance by Borrower
of fifty percent (50%) or more of the outstanding  voting  interests of stock of
Borrower or the equity interest in Borrower to any person or entity.

              (c)  Borrower  commences  a case  or  other  proceeding,  or if an
involuntary case or other proceeding shall be commenced against Borrower seeking
liquidation,  reorganization or other relief with respect to its debts under any
bankruptcy,  insolvency or other  similar  debtor relief law now or hereafter in
effect or seeking the appointment of a trustee, receiver, liquidator,  custodian
or other similar official of it or any substantial part of its property, and any
such involuntary case or other proceeding shall remain  undismissed and unstayed
for a period of sixty (60) days.

              (d)  Borrower   shall  make  an  assignment  for  the  benefit  of
creditors,  or admit in writing its inability to pay its debts generally as they
become due.

              (e) A notice  of lien,  levy or  assessment  is filed of record or
given to Borrower  with  respect to all or any of the  Borrower's  assets by any
federal, state, local department or agency, and such lien, levy or assessment is
not released or paid within a  reasonable  period of time but in no event longer
than twenty (20) days from the date such lien, levy or assessment is filed.

              (f) Lender,  in good faith,  believes  the  prospect of payment or
performance by Borrower under this Note is impaired and if Borrower is unable or
unwilling to provide  adequate

                                       3
99999.9SBY\YOKENS\LAS\65107.3



written  assurances  to Lender of its ability to fully  perform  under this Note
within thirty (30) days following delivery of written notice.

              (g) Any  representation  or warranty of Borrower is not materially
true, correct and complete, or if any material statement,  report or certificate
made or delivered by Borrower or its officers,  employees or agents is not true,
correct and complete when made.

         5.   If  any Event of  Default  shall  occur,  the total of the  unpaid
balance of principal and the accrued  unpaid  interest  (past due interest being
compounded)  shall then begin accruing  interest at the rate stated in the first
paragraph above plus eight percent (8.00%) per annum (the "DEFAULT RATE"), until
such time as all past due  payments  and  accrued  interest  are paid.  Borrower
acknowledges  that the effect of this Default Rate  provision  could  operate to
compound some of the interest  obligations  due, and Borrower  hereby  expressly
assents to such compounding should it occur.

         6.    Borrower:

              (a) waives demand, diligence, presentment for payment, protest and
demand, notice of extension,  dishonor,  protest, demand and non-payment of this
Note; and

              (b) agrees that Borrower will pay any collection  expenses,  court
costs  and  actual  attorney's  fees  which  may be  incurred  by  Lender in the
collection or enforcement of this Note.


         8.   This Note shall be construed according to the laws of the State of
Nevada.

         9.   All notices,  requests and other communications  hereunder must be
