                                          A

         the net issue election is made pursuant to this Section.

the Business Day next preceding the date of such exercise;

                  (b) in case such exercise is in part only, a new Warrant or
Warrants of like tenor, for the number of shares of Common Stock in respect of
which this Warrant shall not have been exercised;

                  (c) each certificate representing shares of Common Stock

Company's securities):

                  THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                  "ACT"), AND HAVE BEEN TAKEN FOR INVESTMENT PURPOSES ONLY, AND
                  NOT WITH A VIEW TO THE DISTRIBUTION THEREOF, AND SUCH
                  SECURITIES MAY NOT BE SOLD, PLEDGED OR TRANSFERRED UNLESS
                  THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT
                  COVERING SUCH SECURITIES OR THE COMPANY RECEIVES AN OPINION OF
                  COUNSEL (WHICH MAY BE COUNSEL FOR THE COMPANY), REASONABLY
                  SATISFACTORY IN FORM AND CONTENT TO THE COMPANY, STATING THAT
                  SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND
                  PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT.

         SECTION 2. INVESTMENT REPRESENTATIONS.

issuable upon exercise of this Warrant) to be purchased by such Holder have not
been registered under the Securities Act of 1933, as amended, or any similar
Federal statute, and the rules and regulations of the Securities and Exchange
Commission, or any other Federal agency at the time administering the Securities
Act of 1933, as amended (the "SECURITIES ACT") by reason of a specific exemption
from the registration provisions of the Securities Act which depends upon, among
other things, the bona fide nature of the investment intent as expressed herein.
The

                                      - 4 -

<PAGE>

Holder further understands that neither this Warrant nor the Common Stock
issuable upon the exercise of this Warrant may be offered, sold or otherwise
transferred, pledged or hypothecated unless or until this Warrant or the Common
Stock issuable upon the exercise of this Warrant, as the case may be, is
registered under the Securities Act or an exemption form such registration is
available. The Holder hereof has had an opportunity to discuss the Company's
business, management and financial affairs with the Company's management and to
obtain any additional information necessary to verify the accuracy of the
information given to such Holder. The Holder hereof represents that such Holder
is an accredited investor under Rule 501(a) of Regulation D of the Securities
Act and that such Holder is able to bear the economic risk of such Holder's
investment in the Company contemplated hereby. The Holder is acquiring this
Warrant for its own account without a view to any distribution thereof in
violation of the Securities Act.

         SECTION 3. MAINTENANCE OF WARRANT REGISTER; ASSIGNMENT AND TRANSFER AND
REPLACEMENT.

         3.1      Registered Holders. The Company will maintain a register
containing the name and address of the Holder of this Warrant. The "REGISTERED
HOLDER" of this Warrant shall be the person in whose name such Warrant is
registered in said warrant register. Any registered Holder of this Warrant may
change such Holder's address as shown on the warrant register by written notice
to the Company requesting such change. Any notice or written communication
required or permitted to be given to the registered Holder of this Warrant shall
be mailed, by certified or registered mail, return receipt requested, postage
prepaid, or delivered to such registered Holder at its address as shown on the
warrant register.

         3.2      Assignment and Transfer of the Warrant. Subject to Section 9
and on the basis of the foregoing representations set forth in Section 2 above,
this Warrant has not been registered under the Securities Act, and neither this
Warrant nor the rights evidenced hereby shall be assigned, pledged, transferred
or otherwise disposed of unless either (a) this Warrant first shall have been
registered under the Securities Act, or (b) the Company first shall have been
furnished with an opinion of legal counsel reasonably satisfactory to the
Company stating that such sale or transfer is an exempted transaction under the
Securities Act and, unless such opinion states that such Warrant may be
transferred by the transferee immediately after acquisition without registration
under the Securities Act, a written agreement by the transferee thereof not to
sell or transfer such Warrant without complying with the requirements provided
for in this subsection 3.2. Upon surrender of this Warrant to the Company for
transfer as an entirety by the registered Holder (as permitted by this Section)
at the offices of the Company referred to in Section 1.1 hereof, with the form
of assignment attached hereto completed and duly executed by the registered
Holder, the Company shall, at the Company's expense, issue a new Warrant of the
same denomination to the assignee.

         3.3      Replacement. In case this Warrant shall be mutilated, lost,
stolen, or destroyed, the Company shall issue a new Warrant of like tenor and
denomination and deliver the same at the holder's expense (a) in exchange and
substitution for and upon surrender and cancellation of the mutilated Warrant,
or (b) in lieu of the Warrant lost, stolen or destroyed, upon receipt of (i) a
reasonably detailed affidavit with respect to the circumstances of any loss,
theft or destruction, and (ii) an indemnity reasonably satisfactory to the
Company.

         SECTION 4. ADJUSTMENT OF STOCK ISSUABLE UPON EXERCISE.

         4.1      Sale of Shares Below Fair Market Value.

                  (a) If at any time or from time to time the Company issues or
sells, or is deemed by the provisions of this Section 4.1 to have issued or
sold, Additional Shares of Common Stock (as hereinafter defined), other than as
a dividend or other distribution on any class of stock as provided in Section
4.2 and other than upon a subdivision or combination of shares of Common Stock
as provided in Section 4.3, for an Effective Price (as hereinafter defined) less
than the Fair Market Value then and in each such case:

         (i)      the number of shares of Common Stock to be received by the
                  Holder hereunder shall be adjusted to that number determined
                  by multiplying (a) the number of shares purchasable hereunder
                  immediately prior to such issuance by (b) a fraction, (i) the
                  numerator of which shall be equal to the number of shares of
                  Common Stock outstanding on a fully-diluted basis (but
                  exclusive of 1,675,000 shares of Common Stock of the Company
                  issuable upon exercise of options to purchase shares of the
                  Company, outstanding on the date hereof, with a strike price
                  above the fair market value of the stock of the Company on the
                  date hereof) immediately after the issuance of such Additional
                  Shares of Common Stock, and (ii) the denominator of which
                  shall be equal to the number of shares of Common Stock
                  outstanding on a fully-diluted basis (but exclusive of
                  1,675,000 shares of Common Stock of the Company issuable upon
                  exercise of options to purchase shares of the Company,
                  outstanding on the date hereof, with a strike price above the
                  fair market value of the stock of the Company on the date
                  hereof) immediately prior to the issuance of the Additional
                  Shares of Common Stock; and

         (ii)     the Exercise Price shall be correspondingly reduced so that
                  the aggregate Exercise Price for all shares of Common Stock
                  covered hereby shall remain unchanged.

                  (b) For the purpose of making any adjustment required under
this Section 4.1, the consideration received by the Company for any issue or
sale of securities shall (i) to the extent it consists of cash, be computed at
the amount of cash received by the Company, (ii) to the extent it consists of
property other than cash, be computed at the fair value of that property as
determined in good faith by the Board of Directors of the Company (the "BOARD")
or, at the request of Majority Investors, by an independent appraiser reasonably
acceptable to the Company and the Majority Investors, at the Company's expense,
and (iii) if Additional Shares of Common Stock, Convertible Securities (as
hereinafter defined) or rights or options to purchase either Additional Shares
of Common Stock or Convertible Securities are issued or sold together with other
stock or securities or other assets of the Company for a consideration which
covers both, be computed as the portion of the consideration so received that
may be reasonably determined in good faith by the Board to be allocable to such
Additional Shares of Common Stock, Convertible Securities or rights or options
or, at the request of the Majority Investors, by an independent appraiser
reasonably acceptable to the Company and the Majority Investors at the Company's
expense.

                  (c) For the purpose of the adjustment required under this
Section 4.1, if the Company issues or sells, or is deemed to have issued or
sold, any rights or options for the purchase of, or stock or other securities
convertible into or exchangeable for, whether directly or indirectly, Additional
Shares of Common Stock (such convertible or exchangeable stock or securities
being hereinafter referred to as "CONVERTIBLE SECURITIES") and if the Effective
Price (as hereinafter defined) of such Additional Shares of Common Stock is less
than Fair Market Value, then in each case the Company shall be deemed to have
issued at the time of the issuance of such rights or options or Convertible
Securities the maximum number of Additional Shares of Common Stock issuable upon
exercise, conversion or exchange thereof and to have received as consideration
for the issuance of such shares an amount equal to the total amount of the
consideration, if any, received by the Company for the issuance of such rights
or options or Convertible Securities, plus, in the case of such rights or
options, the minimum amounts of consideration, if any, payable to the Company
upon the exercise of such rights or options, plus, in the case of Convertible
Securities, the minimum amounts of consideration, if any, payable to the Company
(other than by cancellation of liabilities or obligations evidenced by such
Convertible Securities) upon the conversion or exchange thereof. No further
adjustment of the Exercise Price or new number of Warrant Shares, adjusted upon
the issuance of such rights, options or Convertible Securities, shall be made as
a result of the actual issuance of Additional Shares of Common Stock on the
exercise of any such rights or options or the conversion or exchange of any such
Convertible Securities. If any such rights or options or the conversion or
exchange privilege represented by any such Convertible Securities shall expire
without having been exercised, the Exercise Price or the new number of Warrant
Shares adjusted upon the issuance of such rights, options or Convertible
Securities shall be readjusted to the Exercise Price or, as applicable, the new
number of Warrant Shares which would have been in effect had an adjustment been
made on the basis that the only Additional Shares of Common Stock so issued were
the Additional Shares of Common Stock, if any, actually issued or sold on the
exercise of such rights or options or rights of conversion or exchange of such
Convertible Securities, and such Additional Shares of Common Stock, if any, were
issued or sold for the consideration actually received by the Company upon such
exercise, if any, plus the consideration, if any, actually received by the
Company for the granting of all such rights or options, whether or not
exercised, or, if applicable, the consideration actually received by the Company
for issuing or selling the Convertible Securities actually converted or
exchanged, plus the consideration, if any, actually received by the Company
(other than by cancellation of liabilities or obligations evidenced by such
Convertible Securities) on the conversion or exchange of such Convertible
Securities.

                  (d) For the purpose of the adjustment required under this
Section 4.1, if the Company issues or sells, or is deemed by the provisions of
this subsection to have issued or sold, any rights or options for the purchase
of Convertible Securities and if the Effective Price of the Additional Shares of
Common Stock underlying such Convertible Securities is less than Fair Market
Value, then in each such case the Company shall be deemed to have issued at the
time of the issuance of such rights or options the maximum number of Additional
Shares of Common Stock issuable upon conversion or exchange of the total amount
of Convertible Securities covered by such rights or options and to have received
as consideration for the issuance of such Additional Shares of Common Stock an
amount equal to the amount of consideration, if any, received by the Company for
the issuance of such rights or options, plus the minimum amounts

                                      - 7 -

<PAGE>

of consideration, if any, payable to the Company upon the exercise of such
rights or options and plus the minimum amount of consideration, if any, payable
to the Company (other than by cancellation of liabilities or obligations
evidenced by such Convertible Securities) upon the conversion or exchange of
such Convertible Securities. No further adjustment of the Exercise Price or new
number of Warrant Shares, adjusted upon the issuance of such rights or options,
shall be made as a result of the actual issuance of the Convertible Securities
upon the exercise of such rights or options or upon the actual issuance of
Additional Shares of Common Stock upon the conversion or exchange of such
Convertible Securities. The provisions of paragraph (c) above for the
readjustment of the Exercise Price or new number of Warrant Shares upon the
expiration of rights or options or the rights of conversion or exchange of
Convertible Securities shall apply mutatis mutandis to the rights, options and
Convertible Securities referred to in this paragraph (d).

                  (e) "ADDITIONAL SHARES OF COMMON STOCK" shall mean all shares
of Common Stock issued by the Company on or after the date of this Warrant,
including without limitation any and all shares of Common Stock issued to
holders of options granted under, the Company's existing stock plan entitled
MicroFinancial Incorporated 1998 Equity Incentive Plan (the "PLAN") or the
holders of any other options to purchase Common Stock of the Company, whether or
not subsequently reacquired or retired by the Company, whether such options are
outstanding on the date hereof or issued hereafter, other than shares of Common
Stock issued upon exercise of the Warrants.

                  (f) The "EFFECTIVE PRICE" of Additional Shares of Common Stock
shall mean the quotient determined by dividing the total number of Additional
Shares of Common Stock issued or sold, or deemed to have been issued or sold by
the Company under this Section 4.1, into the aggregate consideration received,
or deemed to have been received (including any consideration receivable or
payable upon exercise or conversion of such rights or option for the purchase of
Additional Shares of Common Stock), by the Company for such issue under this
Section 4.1, for such Additional Shares of Common Stock.

                  (g) Any reduction in the conversion price of any Convertible
Security, whether outstanding on the date of this Warrant or thereafter, or the
subscription price of any option, warrant or right to purchase Common Stock or
any Convertible Security (whether such option, warrant or right is outstanding
on the Issue Date or thereafter), to an Effective Price less than Fair Market
Value shall be deemed to be an issuance of such Convertible Security and the
issuance of all such options, warrants or subscription rights, and the
provisions of this Section 4.1 shall apply thereto mutatis mutandis.

                  (h) Record Date Deemed Date of Issuance. In case the Company
shall take a record of the Holders of shares of its stock of any class for the
purpose of entitling them (i) to receive a dividend or a distribution payable in
Common Stock or in Convertible Securities, or (ii) to subscribe for, purchase or
otherwise acquire Common Stock or Convertible Securities, then such record date
shall be deemed to be the date of the issue or sale of the Additional Shares of
Common Stock issued or sold or deemed to have been issued or sold upon the
declaration of such dividend or the making of such other distribution, or the
date of the granting of such rights of subscription, purchase or other
acquisition, as the case may be.

         4.2      Adjustment for Certain Dividends and Distributions. In case at
any time or from time to time, the holders of Common Stock shall have received,
or (on or after the record date fixed for the determination of shareholders
eligible to receive) shall have become entitled to receive, without payment
therefor other or additional stock, other securities, cash or property by way of
dividend; other than additional shares of Common Stock issued as a stock
dividend or in a stock-split (adjustments in respect of which are provided for
in Section 4.3 hereof), then and in each such case the holder of this Warrant,
on the date such payment is received by such holders of Common Stock or upon the
exercise hereof as provided in Section 1 hereof, shall be entitled to receive
the amount of other or additional stock, other securities, cash or property
which such holder would have received prior to or would have held on the date of
such exercise if on the date hereof it had been the holder of record of the
number of shares of Common Stock then exercisable pursuant to this Warrant and
had thereafter, during the period from the date hereof to and including the date
of such exercise, retained such shares and all such other or additional stock,
other securities, cash or property receivable by such holder as aforesaid during
such period, without interest, giving effect to all further adjustments called
for during such period by Section 4 hereof.

         4.3.     Stock Split and Reverse Stock Split. If at any time there
shall occur any stock split, stock dividend, reverse stock split or other
subdivision or combination of the Company's Common Stock ("STOCK EVENT"), then
the number of shares of Common Stock to be received by the holder of this
Warrant shall be appropriately adjusted such that the proportion of (a) the
number of shares of Common Stock issuable hereunder to (b) the total number of
shares of Common Stock of the Company (on a fully diluted basis, but exclusive
of 1,675,000 shares of Common Stock of the Company issuable upon exercise of
options to purchase shares of the Company, outstanding on the date hereof, with
a strike price above the fair market value of the stock of the Company on the
date hereof) prior to such Stock Event is equal to the proportion of (x) the
number of shares of Common Stock issuable hereunder to (y) the total number of
shares of Common Stock of the Company (on a fully-diluted basis but exclusive of
1,675,000 shares of Common Stock of the Company issuable upon exercise of
options to purchase shares of the Company, outstanding on the date hereof, with
a strike price above the fair market value of the stock of the Company on the
date hereof) after such Stock Event. No adjustment to the Exercise Price shall
be made in connection with any adjustment of the number of shares of Common
Stock receivable upon exercise of this Warrant, except that the Exercise Price
shall be proportionately decreased upon the occurrence of any stock split or
other subdivision of the Common Stock and shall be proportionately increased
upon the occurrence of any reverse stock split or other combination of Common
Stock

         4.4.     No Dilution or Impairment. The Company will not, by amendment
of its certificate of incorporation or through reorganization, consolidation,
merger, dissolution, issue or sale of securities, sale of assets or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of the Warrants, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holders of the
Warrants against dilution or other impairment. Without limiting the generality
of the foregoing, the Company (a) will not increase the par value of any share
of stock receivable upon the exercise of the Warrants

                                      - 9 -

<PAGE>

above the amount payable therefor upon such exercise, and (b) will take all such
action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and non-assessable shares upon the exercise of all
Warrants at the time outstanding.

         4.5.     Certificate as to Adjustment. In each case of an adjustment in
the number of shares of Common Stock or the number or type of other stock,
securities or property receivable on the exercise of the Warrants, the Company
at its expense shall cause its chief financial officer (who may be the
independent public accountants then auditing the books of the Company) to
compute such adjustment in accordance with the terms of the Warrants and prepare
a certificate setting forth such adjustment and showing in detail the facts upon
which such adjustment is based, including a statement of (a) the consideration
received or to be received by the Company for any Additional Shares of Common
Stock issued or sold or deemed to have been issued or sold, (b) the number of
shares of Common Stock outstanding or deemed to be outstanding, and (c) the
Exercise Price. The Company will forthwith mail a copy of each such certificate
to each Holder of a Warrant at the time outstanding.

         4.6.     Notices of Record Date:   In case:

                  (a) the Company shall take a record of the Holders of its
Common Stock (or other stock or securities at the time receivable upon the
exercise of the Warrants) for the purpose of entitling them to receive any
dividend or other distribution, or any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities, or
to receive any other right, or

                  (b) of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or
merger of the Company with or into another person, or any conveyance of all or
substantially all of the assets of the Company to another person, or

                  (c) of any voluntary dissolution, liquidation or winding-up of
the Company, then, and in each such case, the Company will mail or cause to be
mailed to each Holder of a Warrant at the time outstanding a notice specifying,
as the case may be, (i) the date on which a record is to be taken for the
purpose of such dividend, distribution or right, and stating the amount and
character of such dividend, distribution or right, or (ii) the date on which
such reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up is expected to take place, and the time,
if any is to be fixed, as of which the Holders of record of Common Stock (or
such stock or securities at the time receivable upon the exercise of the
Warrants) shall be entitled to exchange their shares of Common Stock (or such
other stock or securities) for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, conveyance,
dissolution, liquidation or winding-up. Such notice shall be mailed at least 30
days prior to the date specified in the notice on which any such action is to be
taken.

         4.7.     Stock Purchase Rights. If at any time or from time to time,
the Company grants or issues to the record holders of the Common Stock any
options, warrants or subscription rights other than pursuant to the Plan
(collectively, the "STOCK PURCHASE RIGHTS") entitling any such

                                     - 10 -

<PAGE>

holder to purchase Common Stock or any security convertible into or exchangeable
for Common Stock or to purchase any other stock or securities of the Company,
upon exercise hereof the Holder shall be entitled to acquire, upon the terms
applicable to such Stock Purchase Rights, the aggregate Stock Purchase Rights
which the Holder could have acquired if the Holder had been the record Holder of
the maximum number of shares of Common Stock issuable upon exercise of this
Warrant on the record date for such grant or issuance of such Stock Purchase
Rights.

         4.8.     Adjustments For Consolidation, Merger, Sale of Assets,
Reorganization, Etc. If the Company effects a capital reorganization or
reclassification of the stock of the Company (other than a change in par value
or as a result of a stock dividend or subdivision, split-up or combination of
shares), or the consolidation or merger of the Company with or into another
person (other than a consolidation or merger in which the Company is the
continuing corporation and which does not result in any change in the Common
Stock), or sells or otherwise disposes of all or substantially all the
properties and assets of the Company as an entirety to any other person, the
Holder of this Warrant, upon the exercise hereof at any time after the
consummation of such reorganization, reclassification, consolidation, merger,
sale or other disposition, shall be entitled to receive, in lieu of the Common
Stock issuable upon such exercise prior to such consummation, the kind and
number of shares of stock or other securities or property of the Company or of
the corporation resulting from such consolidation or surviving such merger or to
which such properties and assets shall have been sold or otherwise disposed to
which such Holder would have been entitled if immediately prior to such
reorganization, reclassification, consolidation, merger, sale or other
disposition such Holder had exercised this Warrant. The provisions of this
subsection 4.8 shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, sales or other dispositions. The
Company shall not effect any such merger, consolidation, or similar
reorganization in which the Company does not survive or in which its Common
Stock changes, unless prior to or simultaneously with the consummation thereof
the successor corporation shall assume by written instrument executed and mailed
or delivered to the Holder of this Warrant at the last address of such Holder
appearing on the books of the Company, the obligations to deliver to such Holder
such shares of stock, securities or assets as, in accordance with the foregoing
provisions, such Holder may be entitled to purchase. Notwithstanding anything to
the contrary set forth herein, in the event that the Asta Transaction is
consummated by August 31, 2003, the adjustments set forth herein shall not apply
and the Warrant shall terminate automatically in accordance with Section 1.1
above.

         4.10     Dissolution. In the event of any dissolution of the Company
following the transfer of all or substantially all of its properties or assets,
the Company, prior to such dissolution, shall at its expense deliver or cause to
be delivered the stock and other securities and property (including cash, where
applicable) receivable by the holders of this Warrant after the effective date
of such dissolution pursuant to this Section 4 to a bank or trust company as a
trustee for the holders of this Warrant.

         4.11     Continuation of Terms. Upon any reorganization, consolidation,
merger or transfer (and any dissolution following any transfer) referred to in
this Section 4, (excluding the Asta Transaction, if consummated by August 31,
2003, which shall then be governed by Section 1.1) this Warrant shall continue
in full force and effect and the terms hereof shall be applicable to the shares
of stock and other securities and property receivable on the exercise of this
Warrant

                                     - 11 -

<PAGE>

after the consummation of such reorganization, consolidation, or merger or the
effective date of dissolution following any such transfer, as the case may be,
and shall be binding upon the issuer of any stock or other securities, including
in the case of any such transfer, the person acquiring all or substantially all
of the properties or assets of the Company, whether or not such person shall
have expressly assumed the terms of this Warrant.

         4.12     Calculations Made to Nearest Cent or Full Share. All
calculations under this Section 4 shall be made to the nearest cent or to the
nearest full share, as the case may be (with one-half of a cent or a share being
rounded to the next highest full cent or share).

         4.13     No Duplicate Adjustments. Notwithstanding any provision in
this Section 4 to the contrary, no adjustment in the number of shares of Common
Stock which the Holder of this Warrant shall be entitled to receive upon the
exercise hereof shall be made if, as a result of the antidilution provisions
contained in the Company's Articles of Organization, if any, the Holder of this
Warrant shall have obtained substantially the same protections against dilution
resulting from the sale of the Company's capital stock at a price below the
exercise price of this Warrant which are intended to be provided by the
provisions of this Section 4.

         SECTION 5. OTHER NOTICES. In case at any time:

                  (a) the Company shall declare any dividend or other
distribution upon its Common Stock payable in stock; or make any special
dividend or other distribution (other than regular cash dividends) to the
Holders of its Common Stock; or

                  (b) the Company shall propose a subdivision of its outstanding
Common Stock into a greater number of shares of Common Stock or propose a
combination of its outstanding Common Stock into a smaller number of shares of
Common Stock; or

                  (c) the Company shall offer for subscription pro rata to the
Holders of its Common Stock or Common Stock any additional shares of stock of
any class or other rights; or

                  (d) the Company shall propose any capital reorganization or
any reclassification of capital stock of the Company or any consolidation,
merger or sale of all or substantially all of its properties and assets; or

                  (e) there shall be a voluntary or involuntary dissolution,
liquidation or winding-up of the Company;

then, and in each of said cases, the Company shall cause notice thereof to be
mailed to the Holder of this Warrant at the last address appearing on the books
of the Company or given by such Holder to the Company for the purpose of notice.
Such notices shall be mailed at least thirty (30) days prior to the date on
which the books of the Company shall close, or a record date shall be taken for
such dividend, distribution, stock split or combination or issue of rights or to
vote upon such capital reorganization, reclassification, consolidation, merger
or sale of properties and assets, as the case may be, and shall specify such
record date or date for the closing of the transfer books.

<PAGE>

         SECTION 6. RESERVATION OF STOCK ISSUABLE UPON EXERCISE.

         The Company shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for issuance and delivery
upon the exercise of this Warrant, such number of its shares of Common Stock as
shall from time to time be issuable upon the exercise of this Warrant; and if at
any time the number of authorized but unissued shares of its Common Stock shall
not be sufficient for such purpose, the Company will take such corporate actions
as may, in the opinion of its counsel, be necessary to increase its authorized
but unissued shares of its Common Stock to such number of shares as shall be
sufficient for such purpose.

         SECTION 7. RIGHTS AS STOCKHOLDER.

         The registered Holder of this Warrant, as such, shall not be entitled
to vote or receive dividends or be deemed the Holder of shares of Common Stock
for any purpose, nor shall anything contained in this Warrant be construed to
confer upon the registered Holder of this Warrant, as such, any of the rights of
a stockholder of the Company or any right to vote, give or withhold consent to
any action by the Company (whether upon any recapitalization, issue of shares,
reclassification of shares, consolidation, merger, conveyance or otherwise),
receive notice of meetings or other action affecting stockholders (except for
notices provided for in this Warrant), receive dividends or subscription rights,
or otherwise until this Warrant shall have been exercised and the shares of
Common Stock purchasable upon the exercise hereof shall have become deliverable
as provided in Section 1 hereof, at which time the person or persons in whose
name or names the certificate or certificates for the shares of Common Stock
being purchased are to be issued shall be deemed the holder or holders of record
of shares of Common Stock for all purposes.

         SECTION 8. REMEDIES.

         The Company stipulates that the remedies at law of the Holder of this
Warrant in the event of any default or threatened default by the Company in the
performance of or compliance with any of the terms of this Warrant are not and
will not be adequate, and that such terms may be specifically enforced by a
decree for the specific performance of any agreement contained herein or by an
injunction against a violation of any of the terms hereof or otherwise.

         SECTION 9. TRANSFERABILITY.

         This Warrant may be transferred or assigned in whole or in part by the
Holder either to an affiliate (as that term is defined in the Securities Act) of
the Holder or to anyone else except for a competitor if the Holder has complied
with the terms and conditions of (i) this Warrant and (ii) all applicable
federal and state securities laws; provided however that (other than in the case
of a transfer or assignment of this Warrant to an affiliate of the Holder), such
compliance shall include, without limitation, the delivery of investment
representation letters and legal opinions reasonably satisfactory to the
Company. Subject to the provisions of this Warrant with respect to compliance
with the Securities Act, title to this Warrant may be transferred by endorsement
(by the Holder executing the Form of Assignment annexed hereto) and delivery in
the same manner

                                      - 13 -

<PAGE>

as a negotiable instrument transferable by endorsement and delivery. For
purposes of this Agreement, "competitor" shall mean any company that is
primarily engaged in the business of manufacturing, selling, licensing or
developing products that are competitive with products being manufactured, sold,
leased, developed or licensed by the Company on the date hereof.

         SECTION 10. NOTICES, ETC.

         All notices and other communications from the Company to the Holder of
this Warrant shall be mailed by recognized overnight courier first class
registered or certified air mail, postage prepaid, at such address as may have
been furnished to the Company in writing by such Holder, or, until an address is
so furnished, to and at the address of the last Holder of this Warrant who has
so furnished an address to the Company.

         SECTION 11. MISCELLANEOUS.

         This Warrant and any term hereof may be changed, waived, discharged or
terminated only by an instrument in writing signed by the party against which
enforcement of such change, waiver, discharge or termination is sought. This
Warrant is being delivered in The Commonwealth of Massachusetts and shall be
construed and enforced in accordance with and governed by the laws of such
commonwealth. All section headings herein are for purposes of reference only and
shall not limit or otherwise affect the meaning hereof. The invalidity or
unenforceability of any provision hereof shall in no way affect the validity or
unenforceability of any other provision.

         IN WITNESS WHEREOF, MICROFINANCIAL INCORPORATED has caused this
instrument to be duly executed by its duly authorized officer this 14th day of
April, 2003.
