Exhibit 10.3

                              CONDITIONAL GUARANTY

                  THIS  CONDITIONAL  GUARANTY,  is  entered  into as of June 10,
2004, by MICROFINANCIAL  INCORPORATED,  a Massachusetts corporation ("MFI"), and
LEASECOMM CORPORATION,  a Massachusetts  corporation and wholly-owned subsidiary
of MFI  ("Leasecomm" and together with MFI,  collectively  referred to herein as
"Guarantor"),  in  favor of and for the  benefit  of ACORN  CAPITAL  GROUP,  LLC
("Lender").

                                    RECITALS

                  A.  Pursuant  to the  Credit  Agreement  dated  as of the date
hereof (as  amended,  supplemented  or modified  from time to time,  the "Credit
Agreement";  capitalized  terms  used  but not  defined  herein  shall  have the
meanings  given  such terms in the Credit  Agreement)  by and among  TimePayment
Corp. LLC, a Delaware limited liability  company and wholly-owned  subsidiary of
MFI ("Borrower"), certain guarantors named therein, including MFI and Leasecomm,
and Lender, Lender has agreed to make the Loan to Borrower; and

                  B. Guarantor, being affiliated with Borrower, acknowledges and
agrees that Guarantor has received and will receive direct and indirect benefits
from the extension of the Loan made to Borrower.

                  C. Guarantor  wishes to grant Lender security and assurance in
order to secure the  payment and  performance  by Borrower of all of its present
and future  Obligations  (as  hereinafter  defined),  and,  to that  effect,  to
guaranty Borrower's Obligations as set forth herein.

                  Accordingly, Guarantor hereby agrees as follows:

                  1. Conditional Guaranty.

                    (a)   Subject   to   Section    1(e),    Guarantor    hereby
unconditionally  and  irrevocably  guarantees  to Lender  the full and  punctual
payment by Borrower,  when due,  whether at the stated due date, by acceleration
or  otherwise  of all  Obligations  (as defined  below) of  Borrower,  howsoever
created,  arising or  evidenced,  voluntary or  involuntary,  whether  direct or
indirect,  absolute or contingent now or hereafter  existing or owing to Lender,
(collectively,  the  "Guaranteed  Obligations").  Except as  provided in Section
1(e),  this  Guaranty  is an  absolute,  unconditional,  continuing  guaranty of
payment  and  not of  collection  of the  Guaranteed  Obligations  and  includes
Guaranteed  Obligations arising from successive  transactions which shall either
continue such Guaranteed  Obligations or from time to time renew such Guaranteed
Obligations  after  the same  has been  satisfied.  This  Guaranty  is in no way
conditioned upon any attempt to collect from Borrower or upon any other event or
contingency, and shall be binding upon and enforceable against Guarantor without
regard  to the  validity  or  enforceability  of  any  document,  instrument  or
agreement  evidencing or governing  the  Obligations  or any other  agreement or
instrument executed in connection therewith (including, without limitation, this
Guaranty) or contemplated thereby (each, a "Credit Document" and,  collectively,
the "Credit Documents"). If for any reason Borrower shall fail or be unable duly
and  punctually to pay any of the  Guaranteed  Obligations  (including,  without
limitation, amounts that would become due but for the operation of the automatic
stay  under  Section  362(a) of the  Bankruptcy  Code,  11 U.S.C.  ss.  362(a)),
Guarantor  will  forthwith pay the same,  in cash. As used herein  "Obligations"
shall mean all  obligations,  liabilities and indebtedness of Borrower to Lender
under the Credit  Agreement and the "Credit  Documents"  referred to therein and
any  documents  relating  thereto,  whether now existing or  hereafter  created,
absolute or contingent, direct or indirect, due or not, whether created directly
or acquired by assignment or otherwise, including, without limitation, the Loans
and the payment  and  performance  of all other  obligations,  liabilities,  and
indebtedness of Borrower to Lender under the Credit Documents, including without
limitation all fees, costs, expenses and indemnity obligations thereunder.

                    (b) In the event any Credit  Document shall be terminated as
a result of the rejection thereof by any trustee,  receiver or liquidating agent
of  Borrower  or  any  of  its   properties  in  any   bankruptcy,   insolvency,
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or similar proceeding,  Guarantor's  obligations hereunder shall continue to the
same extent as if such Credit Document had not been so rejected.

                    (c)  Guarantor  agrees  to  pay  all  reasonable  costs  and
expenses  (including,   without  limitation,   reasonable  attorneys'  fees  and
disbursements)  incurred in connection  with the  enforcement  of the Guaranteed
Obligations  of Borrower to the extent that such costs and expenses are not paid
by Borrower pursuant to the respective Credit Documents.

                    (d)  Guarantor  further  agrees that if any payment  made by
Borrower or  Guarantor  to Lender on any  Guaranteed  Obligation  is  rescinded,
recovered  from or repaid by  Lender,  in whole or in part,  in any  bankruptcy,
insolvency or similar proceeding instituted by or against Borrower or Guarantor,
this  Guaranty  shall  continue  to  be  fully  applicable  to  such  Guaranteed
Obligation  to the same extent as though the payment so  recovered or repaid had
never  originally  been made on such Guaranteed  Obligation  regardless of, and,
without  giving effect to, any discharge or release of  Guarantor's  obligations
hereunder granted by Lender after the date hereof.

                    (e)  Notwithstanding  the  execution  and  delivery  of this
Agreement on the date hereof,  the guaranty  pursuant hereto shall not be deemed
made,  and this Guaranty  shall not be  effective,  until the earlier of the day
that (A) all  obligations  under  the  Fleet  Loan  Agreement  shall  have  been
discharged in full, or (B) Fleet otherwise consents to this Guaranty.

                  2.  Guaranty  Continuing,   Absolute,  Unlimited.  Subject  to
Section  1(e),  the  obligations  of Guarantor  hereunder  shall be  continuing,
absolute, unlimited and unconditional, shall not be subject to any counterclaim,
setoff,  deduction or defense  based upon any claim  Guarantor  may have against
Lender or  Borrower  or any other  person,  and shall  remain in full  force and
effect  without  regard to, and, to the fullest  extent  permitted by applicable
law,  shall  not  be  released,  discharged  or in  any  way  affected  by,  any
circumstance or condition  (whether or not Guarantor shall have any knowledge or
notice thereof) whatsoever which might constitute a legal or equitable discharge
or defense.

                  3. Waiver.  Guarantor  unconditionally and irrevocably waives,
to the fullest  extent  permitted  by  applicable  law: (a) notice of any of the
matters  referred to in Section 2 hereof;  (b) all notices which may be required
by statute,  rule of law or otherwise to preserve any rights  against  Guarantor
hereunder,  including,  without  limitation,  notice of the  acceptance  of this
Guaranty, or the creation,  renewal,  extension,  modification or accrual of the
Guaranteed  Obligations  or notice of any other matters  relating  thereto,  any
presentment,  demand, notice of dishonor,  protest, nonpayment of any damages or
other amounts  payable under any Credit  Document;  (c) any  requirement for the
enforcement,  assertion  or exercise of any right,  remedy,  power or  privilege
under or in respect  of any  Credit  Document,  including,  without  limitation,
diligence in  collection or protection  of or  realization  upon the  Guaranteed
Obligations or any part thereof or any collateral therefor;  (d) any requirement
of  diligence;  (e) any  requirement  to mitigate the damages  resulting  from a
default by Borrower under any Credit Document; (f) the occurrence of every other
condition  precedent to which  Guarantor or Borrower may  otherwise be entitled;
(g) the right to require Lender to proceed against  Borrower or any other person
liable on the Guaranteed Obligations, to proceed against or exhaust any security
held by Borrower or any other person,  or to pursue any other remedy in Lender's
power  whatsoever;  (h) the right to have the property of Borrower first applied
to the discharge of the Guaranteed  Obligations and (i) until such time that all
Guaranteed  Obligations have been  indefeasibly paid in full, any and all rights
it may  now  or  hereafter  have  under  any  agreement  or at law or in  equity
(including,  without limitation,  any law subrogating Guarantor to the rights of
Lender) to assert any claim against or seek contribution, indemnification or any
other form of reimbursement  from Borrower or any other party liable for payment
of any or all of the  Guaranteed  Obligations  for any payment made by Guarantor
under or in connection with this Guaranty or otherwise.

                  Lender may, at its  election,  exercise any right or remedy it
may  have  against  Borrower  without  affecting  or  impairing  in any  way the
liability of Guarantor  hereunder and Guarantor  waives,  to the fullest  extent
permitted by applicable law, any defense arising out of the absence,  impairment
or loss of any right of reimbursement,  contribution or subrogation or any other
right or remedy of  Guarantor  against  Borrower,  whether  resulting  from such
election by Lender or otherwise.  Guarantor waives any defense arising by reason
of any disability or other defense of Borrower or by reason of the cessation for
any cause  whatsoever of the liability,  either in whole or in part, of Borrower
to Lender for the Guaranteed Obligations.

                  Guarantor  assumes  the  responsibility  for being and keeping
informed of the financial  condition of Borrower and of all other  circumstances
bearing upon the risk of nonpayment  of the  Guaranteed  Obligations  and agrees
that Lender shall not have any duty to advise Guarantor of information regarding
any condition or circumstance  or any change in such condition or  circumstance.
Guarantor acknowledges that Lender has not made any representations to Guarantor
concerning the financial condition of Borrower.

                  4. Security.  Subject to Permitted Encumbrances (and the other
Liens  permitted by Section 6.7 of the Credit  Agreement)  and Section 1(e), the
Guaranteed  Obligations  are secured by collateral  more fully  described in the
Credit Documents and the Credit Agreement.

                  5. Miscellaneous.

                    (a) Notices.  Any notice delivered under this Guaranty shall
be given in the  manner,  to the  addresses  and with the  effect  set  forth in
Section 8.1 of the Credit Agreement.

                    (b)  Amendments.  Any term of this  Guaranty may be amended,
waived, discharged or terminated only by an instrument in writing signed by each
party to this Guaranty.  No notice to or demand on Guarantor  shall be deemed to
be a waiver of the  Obligations or of the right of Lender to take further action
without  notice or demand as  provided  in this  Guaranty.  No course of dealing
between Guarantor and Lender shall change,  modify or discharge,  in whole or in
part,  this  Guaranty  or any  Obligations.  No waiver of any term,  covenant or
provision of this Guaranty shall be effective  unless given in writing by Lender
and if so given shall only be effective in the specific instance in which given.

                    (c) Successors and Assigns.  The provisions of this Guaranty
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective  successors  and  assigns,  except that  Guarantor  may not assign or
otherwise transfer any of its rights or Obligations  hereunder without the prior
written consent of Lender (and any attempted assignment or transfer by Guarantor
without such consent shall be null and void).

                    (d) Severability.  Any provision of this Guaranty held to be
invalid,  illegal  or  unenforceable  in  any  jurisdiction  shall,  as to  such
jurisdiction,  be  ineffective to the extent of such  invalidity,  illegality or
unenforceability without effecting the validity,  legality and enforceability of
the remaining  provisions thereof;  and the invalidity of a particular provision
in a particular  jurisdiction  shall not invalidate  such provision in any other
jurisdiction.

                    (e) Right to Deal with  Borrower.  At any time and from time
to time,  without  terminating,  affecting  or  impairing  the  validity of this
Guaranty  or the  obligations  of  Guarantor  hereunder,  Lender  may deal  with
Borrower in the same manner and as fully as if this  Guaranty  did not exist and
shall be entitled,  among other things,  to grant  Borrower,  without  notice or
demand and without affecting Guarantor's liability hereunder,  such extension or
extensions of time to perform, renew, compromise, accelerate or otherwise change
the time for payment of or  otherwise  change the terms of  indebtedness  or any
part  thereof  contained  in or arising  under any Credit  Document or any other
document  evidencing  Obligations  of  Borrower  to  Lender,  or  to  waive  any
obligation of Borrower to perform any act or acts, as Lender may deem advisable.

                    (f)  Governing  Law;  Jurisdiction;  Consent  to  Service of
Process. This Guaranty shall be governed by and construed in accordance with the
laws of the State of New  York.  Guarantor  HEREBY  IRREVOCABLY  SUBMITS  TO THE
JURISDICTION  OF ANY  FEDERAL  OR STATE  COURT  IN THE  STATE OF NEW YORK IN ANY
ACTION,  SUIT OR PROCEEDING  BROUGHT  AGAINST IT AND RELATED TO OR IN CONNECTION
WITH THIS GUARANTY OR ANY OF THE TRANSACTIONS  CONTEMPLATED  HEREBY AND CONSENTS
TO THE PLACING OF VENUE IN NEW YORK COUNTY OR OTHER COUNTY  PERMITTED BY LAW. TO
THE EXTENT  PERMITTED BY APPLICABLE LAW,  GUARANTOR HEREBY WAIVES AND AGREES NOT
TO ASSERT BY WAY OF MOTION, AS A DEFENSE OR OTHERWISE,  IN ANY SUCH SUIT, ACTION
OR PROCEEDING ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF
SUCH COURTS,  THAT THE SUIT,  ACTION OR PROCEEDING IS BROUGHT IN AN INCONVENIENT
FORUM, THAT THE VENUE OF THE SUIT, ACTION OR PROCEEDING IS IMPROPER, OR THAT ANY
CREDIT  DOCUMENT OR INSTRUMENT  REFERRED TO HEREIN MAY NOT BE LITIGATED IN OR BY
SUCH COURTS. TO THE EXTENT PERMITTED BY APPLICABLE LAW,  GUARANTOR AGREES NOT TO
SEEK AND HEREBY WAIVES THE RIGHT TO ANY REVIEW OF THE JUDGMENT OF ANY SUCH COURT
BY ANY COURT OF ANY OTHER  NATION OR  JURISDICTION  WHICH MAY BE CALLED  UPON TO
GRANT AN ENFORCEMENT OF SUCH  JUDGMENT.  EXCEPT AS PROHIBITED BY LAW,  GUARANTOR
HEREBY  WAIVES  ANY  RIGHT  IT MAY  HAVE TO A TRIAL  BY JURY IN  RESPECT  OF ANY
LITIGATION  DIRECTLY OR INDIRECTLY  ARISING OUT OF, UNDER OR IN CONNECTION  WITH
ANY CREDIT DOCUMENT. Each party to this GUARANTY irrevocably consents to service
of process  in the  manner  provided  for  notices in Section  8.1 of the Credit
Agreement.  Nothing in this  Guaranty will affect the right of any party to this
Guaranty to serve process in any other manner permitted by law.

                    (g) Headings; Counterparts. Article and Section headings and
the table of  contents  (if  applicable)  used  herein  are for  convenience  of
reference  only,  are  not  part of this  Guaranty  and  shall  not  affect  the
construction of, or be taken into consideration in interpreting,  this Guaranty.
This Guaranty may be executed in counterparts  (and by different  parties hereto
on different counterparts),  each of which shall constitute an original, but all
of which when taken together shall constitute a single contract.  Delivery of an
executed counterpart of a signature page of this Guaranty or of any other Credit
Document  by telecopy  shall be  effective  as  delivery of a manually  executed
counterpart of this Guaranty or of such other Credit Document.

                    (h) No  Waiver;  Rights  Cumulative.  No course  of  dealing
between  Guarantor  and  Lender,  or  Lender's  failure to  exercise or delay in
exercising  any right,  power or privilege  hereunder  shall operate as a waiver
thereof.  Any  single or  partial  exercise  of any  right,  power or  privilege
hereunder  shall not  preclude  any other or  further  exercise  thereof  or the
exercise of any other  right,  power or  privilege.  All of Lender's  rights and
remedies  hereunder,  whether  established  hereby or by any  other  agreements,
instruments  or documents or by law,  shall be  cumulative  and may be exercised
singly or concurrently.

                    (i) No  Partnership.  The  relationship  between  Lender and
Guarantor  shall  be only of  creditor-debtor  and no  relationship  of  agency,
partner  or joint- or  co-venturer  shall be created  by or  inferred  from this
Guaranty or the other Credit Documents.  Guarantor shall indemnify,  defend, and
save Lender  harmless from any and all claims  asserted  against Lender as being
the agent, partner, or joint-venturer of Guarantor.

                    (j) Entire  Agreement.  This  Guaranty  and the other Credit
Documents embody the entire agreement and  understanding  between  Guarantor and
Secured  Party with respect to the subject  matter  hereunder  and supersede all
prior  conflicting  or  inconsistent  agreements,  consents  and  understandings
relating to such subject matter. Guarantor acknowledges and agrees that there is
no oral agreement  between  Guarantor and Lender which has not been incorporated
in this Guaranty or another Credit Document.

                    (k) Other  Guaranties.  The  execution  and delivery of this
Guaranty shall not supersede,  terminate, modify or supplement in any manner any
other guaranty  previously  executed and delivered to Lender by Guarantor and no
release or  termination  of any  guaranty  shall be  construed  to  terminate or
release any other guaranty unless such guaranty is  specifically  referred to in
any such termination.

                  6. Joint and Several Obligations. All Obligations,  agreements
and liabilities of Guarantor under this Guaranty shall be joint and several.

                  7.  Covenant of  Guarantor.  Guarantor  hereby  covenants  and
agrees that, from and after the date hereof, it will not originate any new lease
financing business other than new leases financed by Borrower.
