plan for the fiscal year 2006  commencing  August 1. The  Revenue  Goal for 2006
will be agreed to by the entire senior management group by August 31, 2005.

CALCULATION OF COMMISSIONS

At  the  end  of  each  quarter,  the  commission  is  calculated  based  on the
achievement of the quarterly goals as per the tables below.  Commission  payable
is  expressed  as a percentage  of the base salary  earned in the  quarter.  The
Company  will  make an  assessment  of the  commissions  owing at the end of the
quarter,  and may at its discretion,  advance  commissions in lieu of payment by
the customer.

PAYMENT OF COMMISSIONS

Commissions  will be  calculated  at the end of each  quarter  -  October  31st,
January 31st, April 30th, and July 31st.

Although the  commission  is based on the sales earned in a particular  quarter,
the  commission is also subject to the Company  receiving the cash for the sales
earned in that  particular  quarter.  In order to not delay the  payment  of the
commission in a particular quarter, once the Accounting department has completed
their quarter-end reporting, the commission will be calculated and every attempt
will be made to pay 50% of it on the next payroll,  while the remaining 50% will
be held back to ensure that the Company  receives  the cash for sales  earned in
that quarter.  The Accounting  department will review the  outstanding  accounts
receivable at the end of each month, and when 90% of the accounts receivable has
been  received,  or at the  discretion of the CFO, the balance of the commission
will be paid on the next  payroll.  Any bad debts will be charged  against total
sales for the quarter.  If all of the cash is not received,  the commission will
be recalculated for the quarter and if repayment of commission is necessary,  it
will be deducted from the next commission and/or from the next payroll.

<PAGE>
                                       -2-

Commission payments will be subject to regular payroll deductions.

If an employee leaves the Company before the end of a quarter,  they will not be
entitled to any commission.

DURATION OF COMMISSION PLAN

This plan has been approved for Fiscal year 2006 only.

EXAMPLE

a)    Annual Salary = $100,000
      Q1 - Target revenue = $200,000
      Q1 - Actual revenue = $150,000

      Attainment of revenue goal = 150,000 / 200,000 x 100% = 75%
      Commission payable = 10% x $25,000 (Q1 salary) = $2,500

b)    Assuming (a) above, and:

      Q2 - Target revenue = $200,000
      Q2 - Actual revenue = $280,000

      Attainment of revenue goal = 280,000 / 200,000 x 100 = 140%
      Commission payable = 65% x $25,000 (Q2 salary) = $16,250

                                CONVERTIBLE NOTE

New York, New York
April 1, 2005                                                         $52,920.00

      FOR VALUE RECEIVED, CASTLE & MORGAN HOLDINGS, INC., a Delaware corporation
(hereinafter called the "Company"), hereby promises to pay to the order of the
holders listed on Schedule A attached hereto or registered assigns
(collectively, the "Holder") the sum of $52,290.00, on July 31, 2006 (the
"Maturity Date"), and to pay interest on the unpaid principal balance hereof at
the rate of three percent (3%) (the "Interest Rate") per annum from April 1,
2005 (the "Issue Date") until the same becomes due and payable, whether at
maturity or upon acceleration or by prepayment or otherwise.

      This Note evidences that certain obligation set forth in the Loan
Agreement dated as of February 26, 2005 by and between the Company and Internet
Finance International Corporation ("Loan Agreement"), which was assigned to the
Holder pursuant to an Allonge and Assignment of Promissory Note dated as of
March 10, 2005. The terms of this Note supercede in their entirety the terms of
the Loan Agreement.

      Interest shall commence accruing on the Issue Date, shall be computed on
the basis of a 365-day year and the actual number of days elapsed and shall be
payable at maturity. All payments due hereunder (to the extent not converted
into common stock, $.001 par value per share (the "Common Stock") in accordance
with the terms hereof) shall be made in lawful money of the United States of
America. All payments shall be made at such address as the Holder shall
hereafter give to the Company by written notice made in accordance with the
provisions of this Note. Whenever any amount expressed to be due by the terms of
this Note is due on any day which is not a business day, the same shall instead
be due on the next succeeding day which is a business day and, in the case of
any interest payment date which is not the date on which this Note is paid in
full, the extension of the due date thereof shall not be taken into account for
purposes of determining the amount of interest due on such date. As used in this
Note, the term "business day" shall mean any day other than a Saturday, Sunday
or a day on which commercial banks in the city of New York, New York are
authorized or required by law or executive order to remain closed.

      This Note is free from all taxes, liens, claims and encumbrances with
respect to the issue thereof and shall not be subject to preemptive rights or
other similar rights of shareholders of the Company and will not impose personal
liability upon the holder thereof.

      The following terms shall apply to this Note:

                          ARTICLE I. CONVERSION RIGHTS

      1.1 Conversion Right. The Holder shall have the right from time to time,
and at any time on or prior to the Maturity Date to convert all or any part of
the outstanding and unpaid principal amount of this Note into fully paid and
non-assessable shares of Common Stock, as such Common Stock exists on the Issue
Date, or any shares of capital stock or other securities of the Company into
which such Common Stock shall hereafter be changed or reclassified at the
conversion price (the "Conversion Price") determined as provided herein (a
"Conversion"). The number of shares of Common Stock to be issued upon each
conversion of this Note shall be determined by dividing the Conversion Amount
(as defined below) by the Conversion Price specified in the notice of
conversion, in the form attached hereto as Exhibit A (the "Notice of
Conversion"), delivered to the Company by the Holder in accordance with Section
1.4 below; provided that the Notice of Conversion is submitted by facsimile (or
by other means resulting in, or reasonably expected to result in, notice) to the
Company before 6:00 p.m., New York, New York time on such conversion date (the
"Conversion Date"). The term "Conversion Amount" means, with respect to any
conversion of this Note, the sum of (1) the principal amount of this Note to be
converted in such conversion plus (2) accrued and unpaid interest, if any, on
such principal amount at the interest rates provided in this Note to the
Conversion Date.

<PAGE>

      1.2 Conversion Price. The Conversion Price shall be $0.025 per share.

      1.3 Authorized Shares. The Company covenants that during the period the
conversion right exists, the Company will reserve from its authorized and
unissued Common Stock a sufficient number of shares, free from preemptive
rights, to provide for the issuance of Common Stock upon the full conversion of
this Note. The Company is required at all times to have authorized and reserved
two times the number of shares that is actually issuable upon full conversion of
the Note based on the Conversion Price of the Note. The Company represents that
upon issuance, such shares will be duly and validly issued, fully paid and
non-assessable. In addition, if the Company shall issue any securities or make
any change to its capital structure which would change the number of shares of
Common Stock into which the Notes shall be convertible at the Conversion Price,
the Company shall at the same time make proper provision so that thereafter
there shall be a sufficient number of shares of Common Stock authorized and
reserved, free from preemptive rights, for conversion of the Note. The Company
(i) acknowledges that it has irrevocably instructed its transfer agent to issue
certificates for the Common Stock issuable upon conversion of this Note, and
(ii) agrees that its issuance of this Note shall constitute full authority to
its officers and agents who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for shares of
Common Stock in accordance with the terms and conditions of this Note.

      If, at any time a Holder of this Note submits a Notice of Conversion, and
the Company does not have sufficient authorized but unissued shares of Common
Stock available to effect such conversion in accordance with the provisions of
this Article I (a "Conversion Default"), subject to Section 4.8, the Company
shall issue to the Holder all of the shares of Common Stock which are then
available to effect such conversion. The portion of this Note which the Holder
included in its Conversion Notice and which exceeds the amount which is then
convertible into available shares of Common Stock (the "Excess Amount") shall,
notwithstanding anything to the contrary contained herein, not be convertible
into Common Stock in accordance with the terms hereof until (and at the Holder's
option at any time after) the date additional shares of Common Stock are
authorized by the Company to permit such conversion. The Company shall use its
best efforts to authorize a sufficient number of shares of Common Stock as soon
as practicable following the earlier of (i) such time that the Holder notifies
the Company or that the Company otherwise becomes aware that there are or likely
will be insufficient authorized and unissued shares to allow full conversion
thereof and (ii) a Conversion Default. The Company shall send notice to the
Holder of the authorization of additional shares of Common Stock and the
Authorization Date.

      1.4 Method of Conversion.

      (a) Mechanics of Conversion. Subject to Section 1.1, this Note may be
converted by the Holder in whole or in part at any time from time to time after
the Issue Date, by (A) submitting to the Company a Notice of Conversion (by
facsimile or other reasonable means of communication dispatched on the
Conversion Date prior to 6:00 p.m., New York, New York time) and (B) subject to
Section 1.4(b), surrendering this Note at the principal office of the Company.

      (b) Surrender of Note Upon Conversion. Notwithstanding anything to the
contrary set forth herein, upon conversion of this Note in accordance with the
terms hereof, the Holder shall not be required to physically surrender this Note
to the Company unless the entire unpaid principal amount of this Note is so
converted. The Holder and the Company shall maintain records showing the
principal amount so converted and the dates of such conversions or shall use
such other method, reasonably satisfactory to the Holder and the Company, so as
not to require physical surrender of this Note upon each such conversion. In the
event of any dispute or discrepancy, such records of the Company shall be
controlling and determinative in the absence of manifest error. Notwithstanding
the foregoing, if any portion of this Note is converted as aforesaid, the Holder
may not transfer this Note unless the Holder first physically surrenders this
Note to the Company, whereupon the Company will forthwith issue and deliver upon
the order of the Holder a new Note of like tenor, registered as the Holder (upon
payment by the Holder of any applicable transfer taxes) may request,
representing in the aggregate the remaining unpaid principal amount of this
Note. The Holder and any assignee, by acceptance of this Note, acknowledge and
agree that, by reason of the provisions of this paragraph, following conversion
of a portion of this Note, the unpaid and unconverted principal amount of this
Note represented by this Note may be less than the amount stated on the face
hereof.

      (c) Payment of Taxes. The Company shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issue and
delivery of shares of Common Stock or other securities or property on conversion
of this Note in a name other than that of the Holder (or in street name), and
the Company shall not be required to issue or deliver any such shares or other
securities or property unless and until the person or persons (other than the
Holder or the custodian in whose street name such shares are to be held for the
Holder's account) requesting the issuance thereof shall have paid to the Company
the amount of any such tax or shall have established to the satisfaction of the
Company that such tax has been paid.

<PAGE>

      (d) Delivery of Common Stock Upon Conversion. Upon receipt by the Company
from the Holder of a facsimile transmission (or other reasonable means of
communication) of a Notice of Conversion meeting the requirements for conversion
as provided in this Section 1.4, the Company shall issue and deliver or cause to
be issued and delivered to or upon the order of the Holder certificates for the
Common Stock issuable upon such conversion within two (2) business days after
such receipt (and, solely in the case of conversion of the entire unpaid
principal amount hereof, surrender of this Note) (such second business day being
hereinafter referred to as the "Deadline") in accordance with the terms hereof.

      (e) Obligation of Company to Deliver Common Stock. Upon receipt by the
Company of a Notice of Conversion, the Holder shall be deemed to be the holder
of record of the Common Stock issuable upon such conversion, the outstanding
principal amount and the amount of accrued and unpaid interest on this Note
shall be reduced to reflect such conversion, and, unless the Company defaults on
its obligations under this Article I, all rights with respect to the portion of
this Note being so converted shall forthwith terminate except the right to
receive the Common Stock or other securities, cash or other assets, as herein
provided, on such conversion. If the Holder shall have given a Notice of
Conversion as provided herein, the Company's obligation to issue and deliver the
certificates for Common Stock shall be absolute and unconditional, irrespective
of the absence of any action by the Holder to enforce the same, any waiver or
consent with respect to any provision thereof, the recovery of any judgment
against any person or any action to enforce the same, any failure or delay in
the enforcement of any other obligation of the Company to the holder of record,
or any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the Holder of any obligation to the Company, and
irrespective of any other circumstance which might otherwise limit such
obligation of the Company to the Holder in connection with such conversion. The
Conversion Date specified in the Notice of Conversion shall be the Conversion
Date so long as the Notice of Conversion is received by the Company before 6:00
p.m., New York, New York time, on such date.

      (f) Delivery of Common Stock by Electronic Transfer. In lieu of delivering
physical certificates representing the Common Stock issuable upon conversion,
provided the Company's transfer agent is participating in the Depository Trust
Company ("DTC") Fast Automated Securities Transfer ("FAST") program, upon
request of the Holder and its compliance with the provisions contained in
Section 1.1 and in this Section 1.4, the Company shall use its best efforts to
cause its transfer agent to electronically transmit the Common Stock issuable
upon conversion to the Holder by crediting the account of Holder's Prime Broker
with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system.

      1.5 Concerning the Shares. The shares of Common Stock issuable upon
conversion of this Note may not be sold or transferred unless (i) such shares
are sold pursuant to an effective registration statement under the Act or (ii)
the Company or its transfer agent shall have been furnished with an opinion of
counsel (which opinion shall be in form, substance and scope customary for
opinions of counsel in comparable transactions) to the effect that the shares to
be sold or transferred may be sold or transferred pursuant to an exemption from
such registration or (iii) such shares are sold or transferred pursuant to Rule
144 under the Act (or a successor rule) ("Rule 144") or (iv) such shares are
transferred to an "affiliate" (as defined in Rule 144) of the Company who agrees
to sell or otherwise transfer the shares only in accordance with this Section
1.5 and who is an Accredited Investor (as defined in the applicable Federal
Securities laws, rules and regulations). Until such time as the shares of Common
Stock issuable upon conversion of this Note have been registered under the Act
or otherwise may be sold pursuant to Rule 144 without any restriction as to the
number of securities as of a particular date that can then be immediately sold,
each certificate for shares of Common Stock issuable upon conversion of this
Note that has not been so included in an effective registration statement or
that has not been sold pursuant to an effective registration statement or an
exemption that permits removal of the legend, shall bear a legend substantially
in the following form, as appropriate:

      1.6 Effect of Certain Events.

            (a) Effect of Merger, Consolidation, Etc. At the option of the
Holder, the sale, conveyance or disposition of all or substantially all of the
assets of the Company, the effectuation by the Company of a transaction or
series of related transactions in which more than 50% of the voting power of the
Company is disposed of, or the consolidation, merger or other business
combination of the Company with or into any other Person (as defined below) or
Persons when the Company is not the survivor shall either: (i) be deemed to be
an Event of Default (as defined in Article III) or (ii) be treated pursuant to
Section 1.6(b) hereof. "Person" shall mean any individual, corporation, limited
liability company, partnership, association, trust or other entity or
organization.

            (b) Adjustment Due to Merger, Consolidation, Etc. If, at any time
when this Note is issued and outstanding and prior to conversion of all of the
Notes, there shall be any merger, consolidation, exchange of shares,
recapitalization (including a forward or reverse stock split), reorganization,
or other similar event, as a result of which shares of Common Stock of the
Company shall be changed into the same or a different number of shares of
another class or classes of stock or securities of the Company or another
entity, or in case of any sale or conveyance of all or substantially all of the
assets of the Company other than in connection with aplan of complete
liquidation of the Company, then the Holder of this Note shall thereafter have
the right to receive upon conversion of this Note, upon the basis and upon the
terms and conditions specified herein and in lieu of the shares of Common Stock
immediately theretofore issuable upon conversion, such stock, securities or
assets which the Holder would have been entitled to receive in such transaction
had this Note been converted in full immediately prior to such transaction
(without regard to any limitations on conversion set forth herein), and in any
such case appropriate provisions shall be made with respect to the rights and
interests of the Holder of this Note to the end that the provisions hereof shall
thereafter be applicable, as nearly as may be practicable in relation to any
securities or assets thereafter deliverable upon the conversion hereof. The
Company shall not effect any transaction described in this Section 1.6(b) unless
(a) it first gives, to the extent practicable, thirty (30) days prior written
notice (but in any event at least fifteen (15) days prior written notice) of the
record date of the special meeting of shareholders to approve, or if there is no
such record date, the consummation of, such merger, consolidation, exchange of
shares, recapitalization, reorganization or other similar event or sale of
assets (during which time the Holder shall be entitled to convert this Note) and
(b) the resulting successor or acquiring entity (if not the Company) assumes by
written instrument the obligations of this Section 1.6(b). The above provisions
shall similarly apply to successive consolidations, mergers, sales, transfers or
share exchanges.

            (c) Adjustment Due to Distribution. If the Company shall declare or
make any distribution of its assets (or rights to acquire its assets) to holders
of Common Stock as a dividend, stock repurchase, by way of return of capital or
otherwise (including any dividend or distribution to the Company's shareholders
in cash or shares (or rights to acquire shares) of capital stock of a subsidiary
(i.e., a spin-off)) (a "Distribution"), then the Holder of this Note shall be
entitled, upon any conversion of this Note after the date of record for
determining shareholders entitled to such Distribution, to receive the amount of
such assets which would have been payable to the Holder with respect to the
shares of Common Stock issuable upon such conversion had such Holder been the
holder of such shares of Common Stock on the record date for the determination
of shareholders entitled to such Distribution.

            (d) Notice of Adjustments. Upon the occurrence of each adjustment or
readjustment of the Conversion Price as a result of the events described in this
Section 1.6, the Company, at its expense, shall promptly compute such adjustment
or readjustment and prepare and furnish to the Holder of a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. The Company shall, upon the written
request at any time of the Holder, furnish to such Holder a like certificate
setting forth (i) such adjustment or readjustment, (ii) the Conversion Price at
the time in effect and (iii) the number of shares of Common Stock and the
amount, if any, of other securities or property which at the time would be
received upon conversion of the Note.

      1.7 Status as Shareholder. Upon submission of a Notice of Conversion by a
Holder, (i) the shares covered thereby shall be deemed converted into shares of
Common Stock and (ii) the Holder's rights as a Holder of such converted portion
of this Note shall cease and terminate, excepting only the right to receive
certificates for such shares of Common Stock and to any remedies provided herein
or otherwise available at law or in equity to such Holder because of a failure
by the Company to comply with the terms of this Note. Notwithstanding the
foregoing, if a Holder has not received certificates for all shares of Common
Stock prior to the tenth (10th) business day after the expiration of the
Deadline with respect to a conversion of any portion of this Note for any
reason, then (unless the Holder otherwise elects to retain its status as a
holder of Common Stock by so notifying the Company) the Holder shall regain the
rights of a Holder of this Note with respect to such unconverted portions of
this Note and the Company shall, as soon as practicable, return such unconverted
Note to the Holder or, if the Note has not been surrendered, adjust its records
to reflect that such portion of this Note has not been converted. In all cases,
the Holder shall retain all of its rights and remedies.

then, upon the occurrence and during the continuation of any Event of Default
specified in Section 2.1, 2.2, 2.3, 2.4, 2.5 or 2.7, at the option of the

shall become immediately due and payable and the Company shall pay to the
Holder, in full satisfaction of its obligations hereunder, an amount equal to
the then outstanding principal amount of this Note plus accrued and unpaid
interest on the unpaid principal amount of this Note to the date of payment. If
the Company fails to pay the amount within five (5) business days of written
notice that such amount is due and payable, then the Holder shall have the right
at any time, so long as the Company remains in default (and so long and to the
extent that there are sufficient authorized shares), to require the Company,

of shares of Common Stock of the Company equal to such amount divided by the
Conversion Price then in effect.

entitled to exercise all rights and remedies available at law or in equity

that the remedy at law for a breach of its obligations under this Note will be
inadequate and agrees, in the event of a breach or threatened breach by the
Company of the provisions of this Note, that the Holder shall be entitled, in

      3.1 Failure or Indulgence Not Waiver. No failure or delay on the part of
the Holder in the exercise of any power, right or privilege hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such power, right or privilege preclude other or further exercise thereof or of
any other right, power or privileges. All rights and remedies existing hereunder
are cumulative to, and not exclusive of, any rights or remedies otherwise
available.
