Exhibit 10.12

                           MICROFINANCIAL INCORPORATED
                    ACORN/AMPAC REGISTRATION RIGHTS AGREEMENT

         This Registration Rights Agreement (the "AGREEMENT") is made as of this
10th day of June, 2004 by and among MicroFinancial Incorporated (the "COMPANY"),
and each of the  holders  set forth on  Schedule A attached  hereto,  along with
their successors and assigns (the "HOLDERS").

                              W I T N E S S E T H:

         WHEREAS,  the Company,  TimePayment  Corp. LLC and Acorn Capital Group,
LLC ("ACORN") are parties to that certain Credit  Agreement dated as of the date
hereof  pursuant  to  which  the  Company  issued  Acorn  that  certain  warrant
certificate  to purchase  shares of Common Stock of the Company  dated as of the
date hereof (the "ACORN WARRANT");

         WHEREAS,   the  Company,   TimePayment  Corp.  LLC  and  Ampac  Capital
Solutions,  LLC ("AMPAC")  are parties to that certain Note  Purchase  Agreement
dated as of the date hereof  pursuant to which the  Company  issued  Ampac those
certain  warrant  certificates to purchase shares of Common Stock of the Company
dated as of the date hereof (the "AMPAC WARRANTS"); and

         WHEREAS,  the Company and the Holders wish to enter into a Registration
Rights  Agreement as set forth herein to provide for  registration of the shares
of Common Stock issuable upon exercise of the Acorn Warrant and Ampac Warrants.

         NOW  THEREFORE,  for good and valuable  consideration,  the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

         1.    Incidental Registration.

               1.1. If the Company at any time  proposes to register  any of its
equity  securities  under the  Securities  Act (other  than a  Registration  (i)
relating to shares of Common  Stock  issuable  upon  exercise of employee  stock
options or in  connection  with any  employee  benefit  or  similar  plan of the
Company or (ii) in  connection  with an  acquisition  by the  Company of another
company),  whether as a result of a primary or secondary offering or pursuant to
registration  rights granted to holders of other securities of the Company,  the
Company  shall,  each such time,  subject to the provisions of Section 1.2, give
prompt  written  notice to the  Holders  of its  intention  to do so and of such
Holders'  rights under this Section 1, at least 20 days prior to the anticipated
filing date of the Registration  Statement relating to such  Registration.  Such
notice  shall  offer all of the  Holders  the  opportunity  to  include  in such
Registration Statement such number of Registrable Securities as each such Holder
may  request.  Upon the  written  request of any such Holder made within 10 days
after the receipt of the  Company's  notice  (which  request  shall  specify the
number of Registrable Securities intended to be disposed of by such Holder), the
Company  shall  use its best  efforts  to  effect  the  Registration  under  the
Securities  Act of all  Registrable  Securities  which the  Company  has been so
requested  to  register  by the  Holders  thereof;  provided,  that  (x) if such
Registration  involves an underwritten  offering,  all Holders  requesting to be
included in the Company's Registration must sell their Registrable Securities to
the  underwriters  selected by the Company on the same terms and  conditions  as
apply to the Company; and (y) if, at any time after giving written notice of its
intention to register any  securities  pursuant to this Section 1.1 and prior to
the effective date of the  Registration  Statement filed in connection with such
Registration,  the Company  shall  determine for any reason not to register such
securities,  the  Company  shall give  written  notice to all  Holders and shall
thereupon be relieved of its obligation to register any  Registrable  Securities
in connection with such Registration. If a Registration pursuant to this Section
1.1  involves an  underwritten  public  offering,  any Holder  requesting  to be
included in such  Registration may elect, in writing prior to the effective date
of the Registration Statement filed in connection with such Registration, not to
register such Registrable  Securities in connection with such Registration.  The
Company shall pay all Registration Expenses in connection with each Registration
of Registrable Securities requested pursuant to this Section 1.

               1.2.  Priority in  Incidental  Registrations.  If a  Registration
pursuant to this  Section 1 involves an  underwritten  offering and the managing
underwriter  advises the Company that, in its good faith opinion,  the number of
equity securities (including all Registrable  Securities) which the Company, the
Holders and any other persons intend to include in such Registration exceeds the
largest number of securities  which can be sold without having an adverse effect
on such offering,  including the price at which such Registrable  Securities can
be sold,  the Company will include in such  Registration  (i) first,  securities
(the "2003  REGISTRABLE  SECURITIES")  that the Company proposes to sell for the
account of other Persons holding certain warrants (the "2003  Warrants")  having
registration  rights  pursuant to that certain  Registration  Rights  Agreement,
dated April 14, 2003 (the "2003  REGISTRATION  RIGHTS  AGREEMENT")  (ii) second,
Acorn Registrable  Securities  proposed to be registered by the Holders thereof,
pro rata  based on the number of Acorn  Registrable  Securities  proposed  to be
registered  by each such  Holder,  (iii)  third,  Ampac  Registrable  Securities
proposed to be registered by the Holders  thereof,  pro rata based on the number
of Ampac Registrable  Securities  proposed to be registered by each such Holder,
and (iv) fourth,  securities that the Company proposes to issue and sell for its
own account.

               1.3. Filing of Registration  Statement.  The Company shall file a
Registration  Statement with the Commission within 60 days after the date hereof
registering  (i) the shares of Common Stock issuable to the holders of the Ampac
Warrants  upon exercise of the Ampac  Warrants,  (ii) the shares of Common Stock
issuable to the holders of the 2003  Warrants upon exercise of the 2003 Warrants
(if such holders  desire such shares to be  registered)  and (iii) the shares of
Common Stock  issuable to the holders of the Acorn  Warrant upon exercise of the
Acorn Warrant (if such holders desire such shares to be registered),  subject to
the  provisions  of  Section  1.2.  Such   Registration  (i)  shall  not  be  an
underwritten  offering,  unless the Company  decides in its sole  discretion  to
engage an underwriter  in connection  with such  Registration  and (ii) shall be
subject to all  provisions  of this  Agreement,  including  without  limitation,
Sections  2.2 and 2.11.  The  Company  shall use its best  efforts  to have such
Registration  Statement  declared  Effective by the  Commission  within 180 days
after the date hereof.

         2.     Registration Procedures.

         In connection  with any offering of Registrable  Securities  registered
pursuant to this Agreement, the Company shall:

               2.1. Prepare and file with the Commission as soon as practicable,
and in any event within 120 days after receipt of a request for Registration,  a
Registration  Statement  on any form for which the Company  then  qualifies  and
which  counsel for the Company shall deem  appropriate,  and which form shall be
available for the sale of the  Registrable  Securities  in  accordance  with the
intended  methods  of  distribution  thereof,  and use  commercially  reasonable
efforts to cause such  Registration  Statement to become and remain Effective as
provided  herein,  provided that at least fifteen (15) days prior to filing with
the Commission a Registration Statement or disclosure document constituting part
of a  Registration  Statement or any  amendments  or  supplements  thereto,  the
Company  will (x) furnish to one  counsel  selected by the Holders of a Majority
covered by such Registration  Statement copies of all such documents proposed to
be filed for said  counsel's  review  and  comment  and (y) notify  each  Holder
covered by such Registration Statement of any stop order issued or threatened by
the Commission and take all reasonable  actions required to prevent the entry of
such stop order or to remove it if entered.

               2.2.  Prepare and file with the  Commission  such  amendments and
supplements  to  such  Registration   Statement  and  any  disclosure   document
constituting part of such Registration Statement used in connection therewith as
may be necessary to keep Effective such  Registration  Statement for a period of
not less than 180 days or such  shorter  period  which will  terminate  when all
Registrable  Securities  covered by such  Registration  Statement have been sold
(but not before the expiration of the 90 day period, if applicable,  referred to
in Section 4(3) of the Securities Act and Rule 174 under the Securities  Act, or
any successor  thereto,  if  applicable),  and comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
Registration  Statement  during  such  period in  accordance  with the  intended
methods of  disposition  by the sellers  thereof set forth in such  Registration
Statement.

               2.3.  Furnish to each  Holder and each  underwriter,  if any,  of
Registrable  Securities  covered by such  Registration  Statement such number of
copies of such Registration Statement, each amendment and supplement thereto (in
each case including all exhibits thereto),  and the disclosure document included
in such Registration Statement (including each preliminary disclosure document),
in  conformity  with the  requirements  of the  Securities  Act,  and such other
documents  as any  Holder may  reasonably  request  in order to  facilitate  the
disposition of the Registrable Securities owned by such Holder.

               2.4. Use commercially  reasonable  efforts to register or qualify
such Registrable Securities under such other state securities or "blue sky" laws
of such  jurisdictions as any Holder,  and  underwriter,  if any, of Registrable
Securities covered by such Registration Statement reasonably requests and do any
and all other acts and things which may be reasonably  necessary or advisable to
enable such Holder and each  underwriter,  if any, to consummate the disposition
in such  jurisdictions  of the  Registrable  Securities  owned  by such  Holder;
provided  that the Company  will not be required to (x) qualify  generally to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this Section 2, (y) subject itself to taxation in any such  jurisdiction
or (z) consent to general service of process in any such jurisdiction.

               2.5.   Immediately   notify  each  Holder  of  such   Registrable
Securities at any time when a disclosure  document  relating thereto is required
to be delivered  under the  Securities  Act of the  happening of any event which
comes to the  Company's  attention  if as a result of such event the  disclosure
document included in such Registration Statement contains an untrue statement of
material fact or omits to state any material fact required to be stated  therein
or necessary to make the statements therein not misleading, and promptly prepare
and furnish to such Holder a supplement or amendment to such disclosure document
so that, as thereafter delivered to the Holders of such Registrable  Securities,
such disclosure document will not contain an untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading.

               2.6.  Use  commercially  reasonable  efforts  to  cause  all such
Registrable  Securities  to be listed on a national  securities  exchange or the
NASDAQ  national  market and on each  securities  exchange  upon  which  similar
securities  issued  by the  Company  may then be  listed,  and  enter  into such
customary   agreements  including  a  listing  application  and  indemnification
agreement in customary  form,  and to provide a transfer agent and registrar for
such Registrable Securities covered by such Registration Statement no later than
the effective date of such Registration Statement.

               2.7.   Enter  into  such  customary   agreements   (including  an
underwriting agreement in customary form) and take all such other actions as the
Holders of a Majority covered by such Registration Statement or the underwriters
retained by such  Holders,  if any,  reasonably  request in order to expedite or
facilitate the disposition of such Registrable  Securities,  including customary
representations, warranties, indemnities and agreements.

               2.8. Make  available for inspection by any Holder covered by such
Registration  Statement,  any  underwriter   participating  in  any  disposition
pursuant to such Registration Statement,  and any attorney,  accountant or other
agent   retained  by  any  such  Holder  or   underwriter   (collectively,   the
"INSPECTORS"),  all financial and other records,  pertinent  corporate documents
and  properties  of the Company,  and cause the  Company's  and its  Affiliates'
officers,  directors and employees to supply all  information and respond to all
inquiries  reasonably  requested by any such  Inspector in connection  with such
Registration Statement.

               2.9. Use  commercially  reasonable  efforts to obtain (a) a "cold
comfort" letter from the Company's  independent  public accountants in customary
form and covering such matters of the type customarily covered by "cold comfort"
letters as the Holders of a Majority  being sold  reasonably  request and (b) at
the time of any  underwritten  sale  pursuant  to a  Registration  Statement,  a
"bring-down  comfort  letter",  dated  as of the  date of such  sale,  from  the
Company's  independent certified public accountants covering such matters of the
type customarily covered by comfort letters as the Holders of a Majority covered
by such Registration Statement and the underwriters reasonably request.

               2.10.  Otherwise use  commercially  reasonable  efforts to comply
with all applicable rules and regulations of the Commission,  and make available
to the  Holders,  as soon  as  reasonably  practicable,  an  earnings  statement
covering a period of at least  twelve  months,  beginning  with the first  month
after the Registration  Statement is Effective,  which earnings  statement shall
satisfy the provisions of the Securities Act and Rule 158 thereunder.

               2.11.  In the event of the issuance of any stop order  suspending
the  effectiveness  of a Registration  Statement,  or of any order suspending or
preventing the use of any related  prospectus or suspending the qualification of
any Registrable  Securities included in such Registration  Statement for sale in
any  jurisdiction,  the Company will use its best efforts promptly to obtain the
withdrawal of such order.

               It  shall  be a  condition  precedent  to the  obligation  of the
Company to take any action  with  respect to  securities  of a Holder  that such
Holder shall furnish to the Company such  information  regarding the  securities
held by such  Holder  and the  intended  method of  disposition  thereof  as the
Company shall reasonably request and as shall be required in connection with the
action taken by the Company.


               Each  Holder  agrees  that,  upon  receipt of any notice from the
Company of the happening of any event of the kind described in Section 2.5, such
Holder will forthwith  discontinue  disposition of Registrable  Securities until
such Holder's  receipt of the copies of the  supplemented or amended  disclosure
document contemplated by Section 2.5 hereof, and, if so directed by the Company,
such Holder will  deliver to the Company (at the  Company's  expense) all copies
(including,  without limitation,  any and all drafts), other than permanent file
copies,  then in such Holder's  possession,  of the disclosure document covering
such Registrable  Securities  current at the time of receipt of such notice.  In
the event the  Company  shall  give any such  notice,  the period  mentioned  in
Section  2.2 shall be  extended  by the  greater of (x) three  months or (y) the
number of days  during the period from and  including  the date of the giving of
such notice  pursuant to Section 2.5 hereof to and  including the date when each
Holder covered by such Registration  Statement shall have received the copies of
the supplemented or amended disclosure document contemplated by Section 5.6.

         3.       Indemnification.

                  3.1.  Indemnification  by the  Company.  In the  event  of any
Registration  of any securities of the Company under the Securities Act pursuant
to this  Agreement,  the Company will indemnify and hold  harmless,  to the full
extent  permitted  by law,  each of the  Holders of any  Registrable  Securities
covered by such Registration Statement, their respective directors and officers,
general  partners,  limited  partners  and managing  directors,  each person who
participates  as an underwriter  in the offering or sale of such  securities and
each other  person,  if any, who  controls,  is controlled by or is under common
control with any such Holder or any such  underwriter  within the meaning of the
Securities  Act (and  directors,  officers,  controlling  persons,  partners and
managing directors of any of the foregoing), against any and all losses, claims,
damages or liabilities,  joint or several,  and expenses  (including any amounts
paid in any settlement  effected with the Company's consent,  which consent will
not be unreasonably withheld) to which such Holder, any such director or officer
or general or limited  partner or managing  director or any such  underwriter or
controlling person may become subject under the Securities Act, state securities
or "blue sky" laws,  common law or  otherwise,  insofar as such losses,  claims,
damages or  liabilities  (or  actions or  proceedings  in  respect  thereof)  or
expenses  arise out of or are based  upon (i) any  untrue  statement  or alleged
untrue statement of any material fact contained,  on the effective date thereof,
in any Registration  Statement under which such securities were registered under
the  Securities  Act,  any  preliminary,  final or summary  disclosure  document
contained therein, or any amendment or supplement thereto,  (ii) any omission or
alleged  omission to state therein a material fact required to be stated therein
or  necessary  to make the  statements  therein  not  misleading,  or (iii)  any
violation or alleged  violation  by the Company of any federal,  state or common
law rule or regulation applicable to the Company and relating to action required
of or inaction  by the Company in  connection  with any such  Registration.  The
Company  shall  reimburse  each such  Holder  and each such  director,  officer,
general  partner,   limited  partner,   managing  director  or  underwriter  and
controlling  person for any legal or any other expenses  reasonably  incurred by
them in connection with investigating or defending such loss, claim,  liability,
action or proceeding, provided, that the Company shall not be liable in any such
case to the extent that any such loss,  claim,  damage,  liability (or action or
proceeding  in respect  thereof)  or expense  arises out of or is based upon any
untrue  statement or alleged  untrue  statement or omission or alleged  omission
made in such Registration Statement or amendment or supplement thereto or in any
such preliminary,  final or summary disclosure  document in reliance upon and in
conformity  with  written  information  furnished  to  the  Company  through  an
instrument  duly  executed  by such  Holder in its  capacity  as a Holder in the
Company or any such  director,  officer,  general or limited  partner,  managing
director  or  underwriter  specifically  stating  that  it is  for  use  in  the
preparation  thereof.  The  indemnity  provided  for herein shall remain in full
force and effect  regardless of any  investigation  made by or on behalf of such
Holder or any such director, officer, general partner, limited partner, managing
director,  underwriter or  controlling  person and shall survive the transfer of
such securities by such Holder.

                  3.2.  Indemnification  by the  Holders and  Underwriters.  Any
 Holder of the Registrable  Securities of which are included in any Registration
 Statement shall,  severally (and not jointly with any other Holder),  indemnify
 and hold  harmless  (in the same  manner and to the same extent as set forth in
 paragraph  (a) above) the  Company  and its  directors,  officers,  controlling
 persons from such  Registration  Statement,  any preliminary,  final or summary
 disclosure document contained therein, or any amendment or supplement,  if such
 statement  or alleged  statement  or omission or alleged  omission  was made in
 reliance  upon and in  conformity  with  written  information  furnished to the
 Company or its  representatives  through an  instrument  duly executed by or on
 behalf  of  such  Holder  specifically  stating  that  it is  for  use  in  the
 preparation  of such  Registration  Statement,  preliminary,  final or  summary
 disclosure document or amendment or supplement,  or a document  incorporated by
 reference  into  any of the  foregoing.  No  Holders  shall  be  liable  in the
 aggregate  for  any  amounts  exceeding  the  product  of the  sale  price  per
 Registrable Security (after deduction of applicable  underwriting discounts and
 commissions and transfer  taxes) and the number of Registrable  Securities sold
 pursuant to such Registration Statement or disclosure document by such Holder.

                  3.3.  Notices of Claims,  etc.  Promptly  after  receipt by an
 indemnified party hereunder of written notice of the commencement of any action
 or proceeding  with respect to which a claim for  indemnification  may be, made
 pursuant to this Section 3, such indemnified  party will, if a claim in respect
 thereof is to be made  against an  indemnifying  party,  promptly  give written
 notice to the indemnifying  party of the commencement of such action,  provided
 that the failure of any  indemnified  party to give  notice as provided  herein
 shall not relieve the indemnifying party of its obligations under the preceding
 subsections of this Section,  except to the extent that the indemnifying  party
 is actually  materially  prejudiced by such failure to give notice. In case any
 such action is brought against an indemnified party, unless in such indemnified
 party's reasonable judgment a conflict of interest between such indemnified and
 indemnifying parties may exist in respect of such claim, the indemnifying party
 will be entitled to  participate  in and,  jointly with any other  indemnifying
 party similarly notified,  to assume the defense thereof, to the extent that it
 may wish, with counsel  reasonably  satisfactory to such indemnified party, and
 after  notice  from the  indemnifying  party to such  indemnified  party of its
 election  to assume the defense  thereof,  the  indemnifying  party will not be
 liable to such indemnified  party for any legal or other expenses  subsequently
 incurred by the latter in connection with the defense  thereof,  unless in such
 indemnified  party's  reasonable  judgment a conflict of interest  between such
 indemnified and parties arises in respect of such claim after the assumption of
 the  defense  thereof,  and the  indemnifying  party will not be subject to any
 liability for any settlement  made without its consent (which consent shall not
 be unreasonably  withheld).  No indemnifying party will consent of any judgment
 or enter into any settlement  which does not include as an  unconditional  term
 thereof the giving by the claimant or plaintiff to such indemnified  party of a
 release  from  all  liability  in  respect  to such  claim  or  litigation.  An
 indemnifying party who is not entitled to, or elects not to, assume the defense
 of a claim will not be  obligated to pay the fees and expenses of more than one
 counsel  in any  single  jurisdiction  for  all  parties  indemnified  by  such
 indemnifying  party  with  respect  to such  claim,  unless  in the  reasonable
 judgment of any indemnified party a conflict of interest may exist between such
 indemnified  party and any other of such  indemnified  parties  with respect to
 such claim, in which event the indemnifying party shall be obligated to pay the
 fees and expenses of such  additional  counsel or counsels as may be reasonably
 necessary.  Notwithstanding  anything to the  contrary  set forth  herein,  and
 without limiting any of the rights set forth above, in any event any party will
 have the right to  retain,  at its own  expense,  counsel  with  respect to the
 defense of a claim.

                  3.4. Other  Indemnification.  Indemnification  similar to that
 specified in the  preceding  subsections  of this  Section 3 (with  appropriate
 modifications)  shall be given by the Company  and each Holder with  respect to
 any  required  Registration  or other  qualification  of  securities  under any
 federal or state law or regulation  or  governmental  authority  other than the
 Securities Act.

                  3.5. Contribution.  In order to provide for just and equitable
 contribution in circumstances in which the indemnity  agreement provided for in
 this Section is for any reason held to be unenforceable  although applicable in
 accordance with its terms, the Company,  the Holders and the underwriters shall
 contribute to the aggregate losses,  liabilities,  claims, damages and expenses
 of the nature contemplated by such indemnity agreement incurred by the Company,
 the Holders and the underwriters, in such proportions that the underwriters are
 responsible   for  that  portion   represented  by  the  percentage   that  the
 underwriting  discount appearing in the disclosure document bears to the public
 offering  price  appearing   therein  and  the  Company  and  the  Holders  are
 responsible  for the  balance;  provided,  however,  that no  person  guilty of
 fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f) of the
 Securities Act) shall be entitled to  contribution  from any Person who was not
 guilty of such  fraudulent  misrepresentation.  As between  the Company and the
 Holders,  such parties shall contribute to the aggregate  losses,  liabilities,
 claims,  damages and  expenses  of the nature  contemplated  by such  indemnity
 agreement  in such  proportion  as  shall be  appropriate  to  reflect  (x) the
 relative benefits received by the Company,  on the one hand, and the Holders of
 the Registrable Securities included in the offering on the other hand, from the
 offering of the Registrable  Securities and any other securities  included such
 offering,  and (y) the relative fault of the Company,  on the one hand, and the
 Holders of the Registrable  Securities included in the offering,  on the other,
 with  respect to the  statements  or  omissions  which  resulted  in such loss,
 liability,  claim,  damage or expense,  or action in respect thereof as well as
 any other relevant equitable considerations.  The relative benefits received by
 the Company, on the one hand, and the Holders of the Registrable  Securities on
 the  other,  with  respect to such  offering  shall be deemed to be in the same
 proportion  as the sum of the  total  purchase  price  paid to the  Company  in
 respect of the  Registrable  Securities  plus the total net  proceeds  from the
 offering  of  any  securities  included  in  such  offering  (before  deducting
 expenses)  received by the  Company  bears to the amount by which the total net
 proceeds from the offering of Registrable Securities (before deducting expenses
 but after  deducting  applicable  underwriting  discounts and  commissions  and
 transfer  taxes)  received by the Holders of the  Registrable  Securities  with
 respect to such  offering  exceeds  the  purchase  price paid to the Company in
 respect  of the  Registrable  Securities,  and in each  case  the net  proceeds
 received from such offering  shall be determined as set forth in the disclosure
 document.  The relative  fault shall be determined by reference to, among other
 things,  whether the untrue or alleged  untrue  statement of a material fact or
 omission or alleged  omission to state a material  fact relates to  information
 supplied  by the  Company or the  Holders of the  Registrable  Securities,  the
 intent of the parties and their relative  knowledge,  access to information and
 opportunity to correct or prevent such  statement or omission.  The Company and
 the Holders of the Registrable  Securities  agree that it would not be just and
 equitable if contribution pursuant to this Section were to be determined by pro
 rata  allocation or by any other method of allocation  which does not take into
 account  the  equitable  considerations  referred  to  herein.  Notwithstanding
 anything to the contrary  contained  herein,  the Company and the Holders agree
 that any  contribution  required  to be made by such  Holder  pursuant  to this
 Section 3.5 shall not exceed the net proceeds from the offering of  Registrable
 Securities   (before   deducting   expenses  but  after  deducting   applicable
 underwriting  discounts and  commissions  and transfer  taxes) received by such
 Holder  with  respect to such  offering.  For  purposes of this  Section,  each
 Person,  if any, who controls a Holder or an underwriter  within the meaning of
 Section 15 of the Securities Act shall have the same rights to  contribution as
 such Holder or Underwriter,  and each director of the Company,  each officer of
 the Company who signed the Registration Statement, and each person, if any, who
 controls  the Company  within the meaning of Section 15 of the  Securities  Act
 shall have the same rights to contribution as the Company.

                  3.6.  Rule 144. The Company  will furnish to any Holder,  upon
 request  made by such  Holder at any time,  a written  statement  signed by the
 Company,  addressed to such Holder,  describing  briefly the action the Company
 has taken or proposes to take to comply  with the  current  public  information
 requirements  of Rule 144 or Rule 144A. The Company will, at the request of any
 Holder,  remove  from the  stock  certificates  representing  such  Registrable
 Securities  that  portion  of  any  restrictive  legend  which  relates  to the
 registration provisions of the Securities Act on the second anniversary date of
 this  Agreement,  provided  that the  Holder is not at this time (or within the
 previous 90 days) and affiliate of the Company.

          4. DEFERRAL; BLACK-OUT.  Notwithstanding anything in this Agreement to
the  contrary,  if the  Company  shall  furnish  to  the  Holders  named  in any
registration  statement filed hereunder a certificate signed by the President or
Chief  Executive  Officer of the Company  stating that the Board of Directors of
the  Company  has made the good faith  determination  (after  consultation  with
counsel) (i) that continued use by the Holders of the Registration Statement for
purposes of effecting offers or sales of Registrable Securities pursuant thereto
would  require,   under  the  Securities  Act,  premature   disclosure  in  such
registration  statement  (or  the  prospectus  relating  thereto)  of  material,
nonpublic information (the "NON-PUBLIC INFORMATION") concerning the Company, its
business  or  prospects  or any  proposed  material  transaction  involving  the
Company,  (ii) that such premature disclosure would be materially adverse to the
Company or any such proposed  material  transaction or would make the successful
consummation by the Company of any such material transaction  significantly less
likely  and (iii)  that it is  therefore  essential  to  suspend  the use by the
Holders of such registration statement (and the prospectus relating thereto) for
purposes  of  effecting  offers  or sales  of  Registrable  Securities  pursuant
thereto,  then the right of the Holders to use the  registration  statement (and
the prospectus  relating  thereto) for purposes of effecting  offers or sales of
Registrable  Shares  pursuant  thereto  shall be  suspended  for a  period  (the
"SUSPENSION  PERIOD") of not more than 120 days after delivery by the Company of
the  certificate  referred  to above in this  Section 4.  During the  Suspension
Period,  none of the  Holders  shall  offer or sell any  Registrable  Securities
pursuant to or in reliance upon the  registration  statement (or the  prospectus
relating  thereto).  Notwithstanding  the  foregoing  (a) if  disclosure  of the
Non-Public  Information  is made during a  Suspension  Period,  then the Company
shall  promptly  terminate  the  Suspension  Period and  immediately  notify the
Holders of such  termination  and (b) the Company may not implement the right to
initiate a Suspension  Period more than twice in any twelve month period. To the
extent that the Company initiates one or more Suspension Periods hereunder,  the
Company shall maintain the  effectiveness of the  Registration  Statement for an
additional number of days equal to the aggregate amount of days that the Company
implemented such Suspension Periods.

         5.    Miscellaneous.

               5.1 No Waiver;  Cumulative  Remedies.  No failure or delay on the
part of any party to this  Agreement in  exercising  any right,  power or remedy
hereunder  shall  operate as a waiver  thereof;  nor shall any single or partial
exercise of any such right,  power or remedy preclude any other further exercise
thereof or the exercise of any other right, power or remedy hereunder.

               5.2  Notices.  All  notices  and  other  communications  from the
Company to the Holders  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  Holders who has so
furnished an address to the Company.

               5.3 Modification,  etc. This Agreement and any term hereof may be

Holders of a Majority of the Acorn Registrable Securities, and the Company. This

after the effective date of this Agreement, enter into any agreement or contract
(whether  written  or  oral)  with  respect  to any of its  securities  which is
inconsistent in any respect with the registration  rights granted by the Company
to the Holders  pursuant  to this  Agreement  or  otherwise  conflicts  with the
provisions hereof.

               5.5 Assignment.  This Agreement shall inure to the benefit and be
binding upon each Holder and its heirs,  successors  and assigns.  The Company's
obligations  under this  Agreement  shall not be assigned,  and its duties under
this Agreement shall not be delegated.

               5.6 Legend.  Any shares issued in connection with the exercise of
the Warrants shall bear the following legend:
