THE FULL AND COMPLETE PAYMENT OF FINAL PRINCIPAL OF, AND INTEREST ON, THIS NOTE
IS UNCONDITIONALLY AND IRREVOCABLY INSURED AT THE TIMES SPECIFIED IN, AND
SUBJECT TO THE TERMS OF, A FINANCIAL GUARANTY INSURANCE POLICY ISSUED BY AMBAC
ASSURANCE CORPORATION.

          Registered Owner: PRUCO LIFE INSURANCE COMPANY OF NEW JERSEY


DELIVERY DATE: March 21, 2000           STATED MATURITY DATE: September 16, 2005


         MFI Finance Corp. I, a corporation duly organized and existing under
the laws of the Commonwealth of Massachusetts (the "Issuer," which term includes
any successor entity under the Indenture referred to below), for value received,
hereby promises to pay to the Registered Owner, or its registered assigns, the
principal sum of ONE MILLION THREE HUNDRED THIRTEEN THOUSAND DOLLARS
($1,313,000.00) in monthly installments beginning on April 17, 2000, and to pay
interest monthly in arrears on the unpaid portion of said principal sum (and, to
the extent that the payment of such interest shall be legally enforceable, on
any overdue installment of interest on this Note) on the sixteenth day of each
calendar month or, if such sixteenth day is not a Business Day, the Business Day
immediately

following (each, a "Payment Date"), for the period from and including the
Delivery Date set forth above through April 15, 2000, and thereafter, monthly
from and including the most recent Payment Date through the day immediately
preceding the applicable Payment Date, until the last day preceding the Final
Payment Date, at the rate of 7.375% per annum (calculated on the basis of a
360-day year consisting of 12 months of 30 days each).

         The principal of this Note shall be payable in installments ending no
later than the Stated Maturity Date hereof unless this Note becomes due and
payable at an earlier date by declaration of acceleration, call for redemption
or otherwise. All reductions in the principal amount of a Note effected by
payments of installments of principal made on any Payment Date shall be binding
upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not such payment is noted on this Note. Each installment of principal
payable on this Note shall be in an amount equal to this Noteholder's pro-rata
share of the Principal Distribution Amount and the Additional Principal Amount,
if any, available to be paid to Noteholders of this Series in accordance with
the priorities of Section 12.02(d) of the Indenture. The principal payable on
this Note shall be paid on each Payment Date beginning on the Initial Payment
Date and ending on the applicable Final Payment Date. All payments of principal
with respect to all of the Notes shall be made on a pro rata basis based upon
the ratio that the Outstanding Principal Amount of a Note bears to the
Outstanding Principal Amount of all Notes; provided, however, that if as a
result of such proration a portion of such principal would be less than $.01,
then such payment shall be decreased to the nearest whole cent, and no
subsequent adjustment shall be made in respect thereof.

         The principal and interest on this Note are payable by wire transfer in
accordance with the terms of the Indenture.

         This Note is one of a duly authorized issue of Notes of the Issuer
designated as its 7.375% Contract-Backed Notes, Series 2000-1, Due September 16,
2005 (herein called the "Notes") issued and to be issued under the Indenture,

MicroFinancial Incorporated (formerly known as Boyle Leasing Technologies,
Inc.), as Servicer, and Norwest Bank Minnesota, National Association, as
Indenture Trustee (the "Indenture Trustee," which term includes any successor
Indenture Trustee under the Indenture), to which the Indenture, and all
indentures supplemental thereto, reference is hereby made for a statement of the
respective rights thereunder of the Issuer, the Indenture Trustee and the
Holders of the Notes, and the terms upon which the Notes are, and are to be,
authenticated and delivered. Each capitalized term used and not otherwise
defined herein has the meaning assigned thereto in the Indenture. This Note is
issued under and is subject to the terms, provisions and conditions of the
Indenture to which the Holder of this Note by virtue of the acceptance hereof
assents and by which such Holder is bound.

         The property of the Trust Estate includes certain Contract Assets and
certain other assets described in the Indenture. The Notes are payable out of
the Trust Estate pari passu among the Noteholders equally and ratably without
prejudice, priority or distinction between any Note by reason of time of issue
or otherwise.

         Unless earlier declared due and payable by reason of an Event of
Default, the Notes are payable only at the time and in the manner provided in
the Indenture and are not redeemable or prepayable at the option of the Issuer
before such time, except that the Notes shall be redeemable at the option of the
Issuer, and in the absence of the exercise thereof, by the Note Insurer in whole
but not in part at any time after the Outstanding Principal Amount of the Notes
declines below 10% of the Outstanding Principal Amount as of the Closing Date at
the applicable Redemption Price plus any fees due under the Indenture. If an





                                       2

Event of Default as defined in the Indenture shall occur and be continuing, the
principal of all the Notes may become or be declared due and payable in the
manner and with the effect provided in the Indenture.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Note may be registered on the Note Register of
the Issuer upon surrender of this Note for registration of transfer at the
office or agency of the Issuer in the United States of America maintained for
such purpose, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Issuer and the Indenture Trustee and duly
executed by the holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Notes of the same Stated Maturity of authorized

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor and the rights of the Holders of the Notes under the Indenture at any
time by the Issuer, the Trustee, the Back-up Servicer, the Servicer and the Note
Insurer without the consent of the Holders of the Notes. The Indenture also
contains provisions permitting the Note Insurer, on behalf of the Holders of all
Notes, to waive compliance by the Issuer with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver shall be conclusive and binding upon the Holder of
this Note and upon all future Holders of this Note and of any Note issued upon
the registration of transfer hereof or in exchange herefor or in lieu hereof
whether or not notation of such consent or waiver is made upon this Note.

         The Notes are issuable only in registered form without coupons in such
authorized denominations as provided in the Indenture and subject to certain
limitations therein set forth.

         This Note and the Indenture shall be governed by and construed in
accordance with the internal laws of the State of New York, without regard to
conflicts of laws principles.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and interest on this Note,
but solely from the assets of the Trust Estate pledged to the Indenture Trustee
under the Indenture and the Note Insurance Policy at the times, place and rate,
and in the coin or currency, herein prescribed.

         The Note Insurer, in consideration of the payment of the premium and
subject to the terms of a Note Insurance Policy to be issued by the Note Insurer
to the Indenture Trustee for the benefit of the holders of the Series 2000-1
Notes (the "Note Insurance Policy"), will unconditionally and irrevocably




                                       3

agree, for the benefit of the Holders (as defined below) that an amount equal to
each Insured Amount and Preference Amount (each as defined below) will be paid
by the Note Insurer to (i) in the case of an Insured Amount, the Indenture
Trustee, as trustee for the Holders, on behalf of the Holders, or (ii) in the
case of a Preference Amount, the receiver, conservator, debtor-in-possession or
trustee in bankruptcy, or the Indenture Trustee, as set forth below, in each
case after a claim by the Indenture Trustee for such Insured Payment is made to
the Note Insurer pursuant to a Notice (as defined below). The Note Insurer's
obligations under the Note Insurance Policy with respect to a particular Insured
Amount or Preference Amount shall be discharged to the extent funds equal to the
applicable Insured Amount or Preference Amount, as the case may be, are received
by the Indenture Trustee or, in the case of a Preference Amount, such other
entity described below, whether or not such funds are properly applied by the
Indenture Trustee or such other entity. Insured Payments shall be made only at
the time set forth in the Note Insurance Policy and no accelerated Insured
Payments shall be made regardless of any acceleration or early redemption of the
Series 2000-1 Notes, unless such acceleration is at the sole option of the Note
Insurer.

         The Note Insurance Policy does not cover (i) premiums, if any, payable
in respect of the Series 2000-1 Notes, (ii) shortfalls, if any, attributable to
any payment of withholding taxes (including penalties and interest in respect of
any such liability) or (iii) any risk other than nonpayment, including the
failure of the Indenture Trustee to make any disbursements of available funds
required under the Indenture to the Holders of the Series 2000-1 Notes.

         The Note Insurer will pay any Insured Amount (other than Preference
Amounts) payable under the Note Insurance Policy no later than 11:00 a.m., New
York City time, on the second Business Day following receipt in New York, New
York on a Business Day by the Note Insurer of a Notice; provided that if such
Notice is received after 12:00 noon, New York City time, on such Business Day,
it will be deemed to be received on the following Business Day. If any such
Notice received by the Note Insurer is not in proper form or is otherwise
insufficient for the purpose of making a claim under the Note Insurance Policy,
it shall be deemed not to have been received by the Note Insurer for purposes of
this paragraph, and the Note Insurer shall promptly so advise the Indenture
Trustee in writing and the Indenture Trustee may resubmit an amended or
corrected Notice. If such an amended or corrected Notice is in proper form and
is otherwise sufficient for the purpose of making a claim under the Note
Insurance Policy, it shall be deemed to have been timely received on the
Business Day of such resubmission subject to the proviso above.

         The Note Insurer will pay any Preference Amount, to or on behalf of a
Holder as provided below, on the third Business Day following receipt on a
Business Day by the Note Insurer of: (i) a certified copy of a final,
non-appealable order of a court or other body exercising jurisdiction in the
applicable Insolvency Proceeding to the effect that such Holder is required to
return such Preference Amount paid during the term of the Note Insurance Policy
because the payments of such amounts were avoided as a preferential transfer or
otherwise rescinded or required to be restored by such Holder (the "Order");
(ii) an assignment in such form as is reasonably required by the Note Insurer,
irrevocably assigning to the Note Insurer all rights and claims of such Holder
relating to or arising under the Indenture or otherwise with respect to such
Preference Amount; (iii) appropriate instruments to effect the appointment of
the Note Insurer as agent for such Holder in any legal proceeding related to
such Preference Amount, such instruments being in a form satisfactory to the
Note Insurer; and (iv) a Notice appropriately completed and executed by the
Indenture Trustee; provided that if such documents are received by the Note
Insurer after 12:00 noon New York City time on such Business Day, they will be
deemed to be received on the following Business Day. Such payment shall be
disbursed to the receiver, conservator, debtor-in-possession or trustee in
bankruptcy named in the Order, and not to the Indenture Trustee or any Holder
directly, unless the Indenture Trustee or such Holder has made a payment of the
Preference Amount to the court or such receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order, in




                                       4

delivery of (a) the items referred to in clauses (i), (ii), (iii) and (iv) above
to the Note Insurer and (b) evidence satisfactory to the Note Insurer that
payment has been made to such court or receiver, conservator,
debtor-in-possession or trustee in bankruptcy named in the Order.

available therefor.

         Solely the Indenture Trustee on behalf of the Holders shall have the
right to make a claim for an Insured Payment under the Note Insurance Policy.

         Subject to the terms of the Indenture, the Note Insurer shall be
