         SECTION 1.  EXERCISE OF WARRANT.

         1.1 Time and Manner of  Exercise.  This Warrant may be exercised by the
Holder  hereof,  in whole or in part,  any time  during the  Exercise  Period by

stock splits, stock dividends,  subdivisions and the like) remain outstanding in
the aggregate.

         1.2  Payment.  Payment  in an amount  equal to the  product  of (a) the

of exercise.

         1.3 When  Exercise  Effective.  Each  exercise of this Warrant shall be
deemed to have been effected  immediately  prior to the close of business on the
Business Day on which this Warrant shall have been surrendered to the Company as
provided in subsection 1.1, and at such time the person or persons in whose name
or names any certificate or  certificates  for shares of Common Stock (or of the
other securities or property to which such Holder is entitled upon such exercise
in  accordance  with the terms  hereof)  shall be issuable upon such exercise as
provided in subsection 1.2, shall be deemed to have become the Holder or Holders
of record thereof.

         1.4 Delivery of Stock  Certificates,  etc. As soon as practicable after
the exercise of this  Warrant,  in whole or in part,  and in any event within 10
days thereafter,  the Company at its expense will cause to be issued in the name

                  (a) a  certificate  or  certificates  for the  number  of full
shares of Common Stock to which such Holder shall be entitled upon such exercise
plus, in lieu of any  fractional  share to which such Holder would  otherwise be
entitled,  cash in an amount equal to the same fraction of the Exercise Price of
one full share of Common  Stock,  which shall be paid to the Holders  thereof on
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

with a legend  substantially  in the  following  form  (in  addition  to,  or in
combination  with, any other legend required under  applicable  state securities
law  and  agreements  or  by-law  provisions  relating  to the  transfer  of the
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.

         The Holder hereof  understands  that this Warrant (and the Common Stock
issuable  upon exercise of this Warrant) to be purchased by such Holder have not
been  registered  under the Securities Act of 1933, as amended (the  "SECURITIES
ACT"),  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 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
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  for  investment  purposes  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 Adjustment  for  Subdivisions,  Combinations  or  Consolidation  of
Common Stock. If the outstanding  shares of Common Stock are subdivided by stock
split,  stock dividends or otherwise,  into a greater number of shares of Common
Stock,  concurrently with the  effectiveness of such  subdivision,  the Exercise
Price  then in  effect  shall be  proportionately  decreased  and the  number of
Warrant Shares shall be  proportionately  increased so that the number of shares
of Common Stock issuable upon the exercise of this Warrant shall be increased in
proportion  to such  increase  in  outstanding  shares of  Common  Stock and the
aggregate  consideration  payable upon the exercise of this Warrant with respect
to the Warrant Shares before giving effect to such subdivision shall not change.
If the outstanding shares of Common Stock shall be combined or consolidated,  by
reclassification  or otherwise,  into a lesser number of shares of Common Stock,
concurrently with the  effectiveness of such combination or  consolidation,  the
Exercise Price then in effect shall be proportionately  increased and the number
of  Warrant  Shares  shall be  proportionately  decreased  so that the number of
shares of Common  Stock  issuable  upon the  exercise of this  Warrant  shall be
decreased in proportion to such decrease in  outstanding  shares of Common Stock
and the aggregate  consideration  payable upon the exercise of this Warrant with
respect to the  Warrant  Shares  before  giving  effect to such  combination  or
consolidation shall not change.

         4.2  No  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
hereunder against 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  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.

         4.3 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 number of
Warrant  Shares  issuable upon  exercise of this  Warrant,  and (b) the Exercise
Price.  The Company will forthwith mail a copy of each such  certificate to each
Holder of a Warrant at the time outstanding.

         4.4. 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 any stock split,  stock dividend,  subdivision,
combination or consolidation, 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  any  stock  split,  stock  dividend,  subdivision,  combination  or
consolidation, 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 twenty (20) days prior to the date  specified in
the notice on which any such action is to be taken.

         4.5   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   4.5   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.

         4.6  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.

         4.7  Continuation  of Terms.  Upon any  reorganization,  consolidation,
merger or transfer (and any dissolution  following any transfer)  referred to in
this  Section 4, 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 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.

         4.8  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).

         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 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 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

                  (d) 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
twenty  (20)  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.

         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 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 or any Subsidiary on or after
the  date  hereof.  Notwithstanding  the  foregoing,  this  Warrant  may only be
assigned in part if the Holder is assigning the right to receive at least 25,000
Warrant Shares (as adjusted for stock splits, stock dividends,  subdivisions and
the like) or all Warrant Shares  represented by this Warrant if less than 25,000
Warrant Shares (as adjusted for stock splits, stock dividends,  subdivisions and
the like) remain outstanding in the aggregate.

         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 ____ day of
June, 2004.
