                             SECURED REVOLVING NOTE

      FOR VALUE RECEIVED, each of Thomas Equipment, INC. (f/k/a Maxim Mortgage

or, if different, the aggregate principal amount of all "Revolving Loans" (as
such term is defined in the Security Agreement referred to below), together with
any accrued and unpaid interest hereon, on November 9, 2007 (the "Maturity
Date")

      Capitalized terms used herein without definition shall have the meanings
ascribed to such terms in the Security and Purchase Agreement among the
Borrowers and the Holder dated as of November 9, 2004 (as amended, modified and
supplemented from time to time, the "Security Agreement").

The following terms shall apply to this Note:

                                   ARTICLE I
                           CONTRACT RATE & PREPAYMENTS

      1.1. Interest Rate. Subject to Sections 3.11, 4.1 and 5.7 hereof, interest
payable on this Note shall accrue at a rate per annum equal to the "prime rate"
published in The Wall Street Journal from time to time (the "Prime Rate"), plus
three percent (3%) (the "Contract Rate"). The Prime Rate shall be increased or
decreased as the case may be for each increase or decrease in the Prime Rate in
an amount equal to such increase or decrease in the Prime Rate; each change to
be effective as of the day of the change in such rate in accordance with the
terms of the Security Agreement. Subject to Section 1.2, the Contract Rate shall
not be less than seven and one-half percent (7.50%).

      1.2. Contract Rate Adjustments and Payments. The Contract Rate shall be
calculated on the last business day of each month hereafter until the Maturity
Date (each a "Determination Date") and shall be subject to adjustment as set
forth herein. If (i) Thomas Equipment shall have registered the shares of Thomas
Equipment's common stock delivered to the Holder on the Closing Date and the
shares of Thomas Equipment's Common underlying each of the conversion of the
Minimum Borrowing Notes, the Secured Convertible Term Note, the Options and that
certain warrant issued to Holder on a registration statement declared effective
by the Securities and Exchange Commission (the "SEC"), and (ii) the market price
(the "Market Price") of the Common Stock as reported by Bloomberg, L.P. on the
Principal Market (as defined below) for the five (5) trading days immediately
preceding a Determination Date exceeds the then applicable Fixed Conversion
Price by at least twenty five percent (25%), the Contract Rate for the
succeeding calendar month shall automatically be reduced by 200 basis points
(200 b.p.) (2.0%) for each incremental twenty five percent (25%) increase in the
Market Price of the Common Stock above the then applicable Fixed Conversion
Price. Notwithstanding the foregoing (and anything to the contrary contained in
herein), in no event shall the Contract Rate be less than zero percent (0%).
Interest shall be (i) calculated on the basis of a 360 day year, and (ii)
payable monthly, in arrears, commencing on December 1, 2004 and on the first
business day of each consecutive calendar month thereafter until the Maturity
Date (and on the Maturity Date), whether by acceleration or otherwise (each, a
"Contract Rate Payment Date").


                                       1
<PAGE>

      1.3. Allocation of Principal to Minimum Borrowing Note. In the event that
the amount due and payable hereunder should equal or exceed $8,000,000, to the
extent that the outstanding balance on the Minimum Borrowing Note shall be less
than $8,000,000 (the difference of $8,000,000 less the actual balance of the
Minimum Borrowing Note, the "Available Minimum Borrowing"), such portion of the
balance hereof as shall equal the Available Minimum Borrowing shall be deemed to
be simultaneously extinguished on this Note and transferred to, and evidenced
by, a Minimum Borrowing Note.

                                   ARTICLE II
                           HOLDER'S CONVERSION RIGHTS

      2.1. Optional Conversion. Subject to the terms of this Article II, the
Holder shall have the right, but not the obligation, at any time until the
Maturity Date, or during an Event of Default (as defined in Article IV), and to
convert all or any portion of the outstanding Principal Amount and/or accrued
interest and fees due and payable into fully paid and nonassessable restricted
shares of the Common Stock at the Fixed Conversion Price (defined below). For
purposes hereof, subject to Section 2.5 hereof, the "Fixed Conversion Price"
means an amount equal to $1.50.

      2.2. Conversion Limitation. Notwithstanding anything contained herein to
the contrary, the Holder shall not be entitled to convert pursuant to the terms
of this Note an amount that would be convertible into that number of Conversion
Shares which would exceed the difference between the number of shares of Common
Stock beneficially owned by such Holder or issuable upon exercise of the warrant
and the option held by such Holder and 9.99% of the outstanding shares of Common
Stock of Thomas Equipment. For the purposes of the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Exchange Act and Regulation 13d-3 thereunder. The Conversion Shares
limitation described in this Section 2.2 shall automatically become null and
void without any notice to any Borrower upon the occurrence and during the
continuance beyond any applicable grace period of an Event of Default, or upon
65 days prior notice to Thomas Equipment.


                                       2
<PAGE>

      2.3. Mechanics of Holder's Conversion. In the event that the Holder elects
to convert this Note into Common Stock, the Holder shall give notice of such
election by delivering an executed and completed notice of conversion ("Notice
of Conversion") to Thomas Equipment and such Notice of Conversion shall provide
a breakdown in reasonable detail of the Principal Amount, accrued interest and
fees that are being converted. On each Conversion Date (as hereinafter defined)
and in accordance with its Notice of Conversion, the Holder shall make the
appropriate reduction to the Principal Amount, accrued interest and fees as
entered in its records and shall provide written notice thereof to Thomas
Equipment on the Conversion Date. Each date on which a Notice of Conversion is
delivered or telecopied to Thomas Equipment in accordance with the provisions
hereof shall be deemed a Conversion Date (the "Conversion Date"). A form of
Notice of Conversion to be employed by the Holder is annexed hereto as Exhibit
A. Pursuant to the terms of the Notice of Conversion, Thomas Equipment will
issue instructions to the transfer agent accompanied by an opinion of counsel
within two (2) business days of the date of the delivery to Thomas Equipment of
the Notice of Conversion and shall cause the transfer agent to transmit the
certificates representing the Conversion Shares to the Holder by crediting the
account of the Holder's designated broker with the Depository Trust Corporation
("DTC") through its Deposit Withdrawal Agent Commission ("DWAC") system within
three (3) business days after receipt by Thomas Equipment of the Notice of
Conversion (the "Delivery Date"). In the case of the exercise of the conversion
rights set forth herein the conversion privilege shall be deemed to have been
exercised and the Conversion Shares issuable upon such conversion shall be
deemed to have been issued upon the date of receipt by Thomas Equipment of the
Notice of Conversion. The Holder shall be treated for all purposes as the record
holder of such Common Stock, unless the Holder provides Thomas Equipment written
instructions to the contrary.

      2.4. Late Payments. Each Borrower understands that a delay in the delivery
of the shares of Common Stock in the form required pursuant to this Article
beyond the Delivery Date could result in economic loss to the Holder. As
compensation to the Holder for such loss, each Borrower agrees to jointly and
severally pay late payments to the Holder for late issuance of such shares in
the form required pursuant to this Article III upon conversion of the Note, in
the amount equal to $500 per business day after the Delivery Date. Each Borrower
shall pay any payments incurred under this Section in immediately available
funds upon demand.

      2.5. Adjustment Provisions. The Fixed Conversion Price and number and kind
of shares or other securities to be issued upon conversion determined pursuant
to Section 2.1 shall be subject to adjustment from time to time upon the
happening of certain events while this conversion right remains outstanding, as
follows:

            A. Reclassification. If Thomas Equipment at any time shall, by
reclassification or otherwise, change the Common Stock into the same or a
different number of securities of any class or classes, this Note, as to the
unpaid Principal Amount and accrued interest thereon, shall thereafter be deemed
to evidence the right to purchase an adjusted number of such securities and kind
of securities as would have been issuable as the result of such change with
respect to the Common Stock (i) immediately prior to or (ii) immediately after,
such reclassification or other change at the sole election of the Holder.


                                       3
<PAGE>

            B. Stock Splits, Combinations and Dividends. If the shares of Common
Stock are subdivided or combined into a greater or smaller number of shares of
Common Stock, or if a dividend is paid on the Common Stock or any preferred
stock issued by Thomas Equipment in shares of Common Stock, the Fixed Conversion
Price shall be proportionately reduced in case of subdivision of shares or stock
dividend or proportionately increased in the case of combination of shares, in
each such case by the ratio which the total number of shares of Common Stock
outstanding immediately after such event bears to the total number of shares of
Common Stock outstanding immediately prior to such event.

            C. Share Issuances. Subject to the provisions of this Section 2.5,
if Thomas Equipment shall at any time prior to the conversion or repayment in
full of the Principal Amount issue any shares of Common Stock or securities
convertible into Common Stock to a person other than the Holder (except (i)
pursuant to Subsections A or B above; (ii) pursuant to options, warrants, or
other obligations to issue shares outstanding on the date hereof as disclosed to
Holder in writing; (iii) pursuant to options that may be issued under any
employee incentive stock option and/or any qualified stock option plan adopted
by Thomas Equipment or (iv) pursuant to an acquisition by Borrower permitted
under the terms of the Security Agreement) for a consideration per share (the
"Offer Price") less than the Fixed Conversion Price in effect at the time of
such issuance, then the Fixed Conversion Price shall be immediately reset to
such lower Offer Price. For purposes hereof, the issuance of any security of
Thomas Equipment convertible into or exercisable or exchangeable for Common
Stock shall result in an adjustment to the Fixed Conversion Price upon the
issuance of such securities.

            D. Computation of Consideration. For purposes of any computation
respecting consideration received pursuant to Subsection C above, the following
shall apply:

                  (a) in the case of the issuance of shares of Common Stock for
cash, the consideration shall be the amount of such cash, provided that in no
case shall any deduction be made for any commissions, discounts or other
expenses incurred by Thomas Equipment for any underwriting of the issue or
otherwise in connection therewith;

                  (b) in the case of the issuance of shares of Common Stock for
a consideration in whole or in part other than cash, the consideration other
than cash shall be deemed to be the fair market value thereof as determined in
good faith by the Board of Directors of Thomas Equipment (irrespective of the
accounting treatment thereof); and

                  (c) Upon any such exercise, the aggregate consideration
received for such securities shall be deemed to be the consideration received by
Thomas Equipment for the issuance of such securities plus the additional minimum
consideration, if any, to be received by Thomas Equipment upon the conversion or
exchange thereof (the consideration in each case to be determined in the same
manner as provided in clauses (a) and (b) of this Subsection (D)).

      2.6. Reservation of Shares. During the period the conversion right exists,
Thomas Equipment will reserve from its authorized and unissued Common Stock a
sufficient number of shares to provide for the issuance of Common Stock upon the
full conversion of this Note. Thomas Equipment represents that upon issuance,
such shares will be duly and validly issued, fully paid and non-assessable.
Thomas Equipment agrees that its issuance of this Note shall constitute full
authority to its officers, agents, and transfer agents who are charged with the
duty of executing and issuing stock certificates to execute and issue the
necessary certificates for shares of Common Stock upon the conversion of this
Note.

the Holder hereof in the exercise of any power, right or privilege hereunder

law. Any such provision which may prove invalid or unenforceable under any law
shall not affect the validity or unenforceability of any other provision of this
Note. Nothing contained herein shall be deemed or operate to preclude the Holder
