incorporated in this Registration Statement by reference:

          (a) The  Registrant's  prospectus  filed under Rule  424(b)  under the
     Securities Act of 1933.

          (b) Not applicable.

          (c) The description of the Registrant's  Common Stock contained in the
     Registrant's  registration  statement on Form 8-A filed under Section 12 of
     the Exchange Act on October 11, 2000,  including any  amendments or reports
     filed for the purpose of updating such description.

     All  documents  filed with the  Commission  by the  Registrant  pursuant to
Sections  13(a),  13(c), 14 and 15(d) of the Exchange Act subsequent to the date
of this  Registration  Statement  and prior to the  filing  of a  post-effective
amendment  hereto which  indicates that all securities  offered hereby have been
sold or which deregisters all securities then remaining unsold,  shall be deemed
to be  incorporated  herein by reference and made a part hereof from the date of
filing of such documents. Any statement contained in this Registration Statement
or in a document  incorporated or deemed to be incorporated by reference  herein
shall be deemed to be modified or superseded  for purposes of this  Registration
Statement  to the  extent  that a  statement  contained  herein  or in any other
subsequently  filed  document which also is or is deemed to be  incorporated  by
reference  herein  modifies or  supersedes  such  statement.  Any  statement  so
modified or superseded shall not be deemed, except as so modified or superseded,
to constitute a part of this Registration Statement.


Item 4.  Description of Securities.

          Not applicable.

Item 5.  Interests of Named Experts and Counsel.

     The validity of the securities  offered under this  Registration  Statement
will be passed  upon by  Edwards & Angell,  LLP,  101  Federal  Street,  Boston,
Massachusetts  02110-1800.  Certain  partners and employees of Edwards & Angell,
LLP own shares of common  stock of the  Registrant  with a fair market  value in
excess of $50,000.

Item 6.  Indemnification of Directors and Officers.

     Section 145 of the Delaware  General  Corporation Law provides,  in effect,
that any  person  made a party to any action by reason of the fact that he is or
was serving as a director, officer, employee or other agent of a corporation, or
in such a capacity with another  entity at the request of the  corporation,  may
and, in certain cases,  must be indemnified  by the Registrant  against,  in the
case of a non-derivative  action,  judgments,  fines, amounts paid in settlement
and reasonable expenses (including  attorneys' fees) incurred by him as a result
of such  action,  and in the case of a  derivative  action,  against  reasonable
expenses  (including  attorneys'  fees), if in either type of action he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
Registrant's  best  interests.   This  indemnification  does  not  apply,  in  a
derivative  action,  to matters as to which it is  adjudged  that the  director,
officer, employee or other agent is liable to the Registrant,  unless upon court
order it is determined that,  despite such adjudication of liability but in view
of all the  circumstances  of the case, he is fairly and reasonably  entitled to
indemnity  for  expenses,  and,  in a  non-derivative  action,  to any  criminal
proceeding in which such person had reasonable  cause to believe his conduct was
unlawful.

     The  Registrant's  certificate of  incorporation  provides that none of its
directors  or  officers  or  other  parties  whom it has  requested  to serve as
directors, officers, trustees or in similar capacities with other entities shall
be liable to the Registrant or its  stockholders  for monetary  damages deriving
from an action to which such  persons  were party on account of them serving the
Registrant  or at its  request  to the  fullest  extent  not  prohibited  by the
Delaware General Corporation Law.

     The  Registrant  has  entered  into  indemnification  agreements  with  its
directors  and  officers.  Subject to certain  limited  exceptions,  under these
agreements,  the  Registrant  will  be  obligated,  to the  fullest  extent  not
prohibited by the Delaware General  Corporation Law, to indemnify such directors
and officers against all expenses,  judgments,  fines and penalties  incurred in
connection with the defense or settlement of any actions brought against them by
reason of the fact that they were directors or officers of the  Registrant.  The
Registrant also maintains  liability insurance for its directors and officers in
order to limit its exposure to liability  for  indemnification  of its directors
and officers.

Item 7.  Exemption From Registration Claimed.

     Not applicable.

Item 8.  Exhibits.

23.1      Consent of Deloitte & Touche LLP (independent accountants)

23.2      Consent of Edwards & Angell (included in Exhibit 5)

24        Power of Attorney  (included on signature  pages to this  Registration
          Statement)

Item 9.  Undertakings.

       (a)      The Registrant hereby undertakes:

                (1) To file,  during  any  period  in which  offers or sales are
being made, a post-effective amendment to this Registration Statement:

                    (i) To include any prospectus  required by Section  10(a)(3)
          of the Securities Act of 1933, as amended (the "Securities Act");

                    (ii) To  reflect  in the  prospectus  any  facts  or  events
          arising after the effective  date of this  Registration  Statement (or
          the most recent post-effective amendment thereof) which,  individually
          or in the aggregate, represent a fundamental change in the information
          set forth in this Registration Statement; and

                    (iii) To include any  material  information  with respect to
          the plan of distribution not previously disclosed in this Registration
          Statement  or  any  material  change  to  such   information  in  this
          Registration Statement;

          provided, however, that paragraphs (i) and (ii) shall not apply if the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs is contained in periodic reports filed by the Registrant  pursuant to
Section  13 or  Section  15(d) of the  Exchange  Act that  are  incorporated  by
reference in this Registration Statement;

          (2) For the purpose of determining  any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

     (b)  The  Registrant  hereby  further  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  Annual  Report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act that is  incorporated  by reference in the  Registration  Statement
shall be deemed to be a new  registration  statement  relating to the securities
offered  therein,  and the  offering  of such  securities  at that time shall be
deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the Registrant's bylaws, or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange  Commission such
indemnification  is against public policy as expressed in the Securities Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

     All  documents  filed with the  Commission  by the  Registrant  pursuant to
Sections  13(a),  13(c), 14 and 15(d) of the Exchange Act subsequent to the date
of this  Registration  Statement  and prior to the  filing  of a  post-effective
amendment  hereto which  indicates that all securities  offered hereby have been

subsequently  filed  document which also is or is deemed to be  incorporated  by
reference  herein  modifies or  supersedes  such  statement.  Any  statement  so
modified or superseded shall not be deemed, except as so modified or superseded,
to constitute a part of this Registration Statement.

Item 4.  Description of Securities.

          Not applicable.

Item 5.  Interests of Named Experts and Counsel.

     The validity of the securities  offered under this  Registration  Statement
will be passed  upon by  Edwards & Angell,  LLP,  101  Federal  Street,  Boston,
Massachusetts  02110-1800.  Certain  partners and employees of Edwards & Angell,
LLP own shares of common  stock of the  Registrant  with a fair market  value in
excess of $50,000.

Item 6.  Indemnification of Directors and Officers.

     Section 145 of the Delaware  General  Corporation Law provides,  in effect,
that any  person  made a party to any action by reason of the fact that he is or
was serving as a director, officer, employee or other agent of a corporation, or
in such a capacity with another  entity at the request of the  corporation,  may
and, in certain cases,  must be indemnified  by the Registrant  against,  in the
case of a non-derivative  action,  judgments,  fines, amounts paid in settlement
and reasonable expenses (including  attorneys' fees) incurred by him as a result
of such  action,  and in the case of a  derivative  action,  against  reasonable
expenses  (including  attorneys'  fees), if in either type of action he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
Registrant's  best  interests.   This  indemnification  does  not  apply,  in  a
derivative  action,  to matters as to which it is  adjudged  that the  director,
officer, employee or other agent is liable to the Registrant,  unless upon court
order it is determined that,  despite such adjudication of liability but in view
of all the  circumstances  of the case, he is fairly and reasonably  entitled to
indemnity  for  expenses,  and,  in a  non-derivative  action,  to any  criminal
proceeding in which such person had reasonable  cause to believe his conduct was
unlawful.

     The  Registrant's  certificate of  incorporation  provides that none of its
directors  or  officers  or  other  parties  whom it has  requested  to serve as
directors, officers, trustees or in similar capacities with other entities shall
be liable to the Registrant or its  stockholders  for monetary  damages deriving
from an action to which such  persons  were party on account of them serving the
Registrant  or at its  request  to the  fullest  extent  not  prohibited  by the
Delaware General Corporation Law.

     The  Registrant  has  entered  into  indemnification  agreements  with  its
directors  and  officers.  Subject to certain  limited  exceptions,  under these
agreements,  the  Registrant  will  be  obligated,  to the  fullest  extent  not
prohibited by the Delaware General  Corporation Law, to indemnify such directors
and officers against all expenses,  judgments,  fines and penalties  incurred in
connection with the defense or settlement of any actions brought against them by
reason of the fact that they were directors or officers of the  Registrant.  The
Registrant also maintains  liability insurance for its directors and officers in
order to limit its exposure to liability  for  indemnification  of its directors
and officers.

Item 7.  Exemption From Registration Claimed.

     Not applicable.

24        Power of Attorney  (included on signature  pages to this  Registration
          Statement)

Item 9.  Undertakings.

       (a)      The Registrant hereby undertakes:

                (1) To file,  during  any  period  in which  offers or sales are
being made, a post-effective amendment to this Registration Statement:

                    (i) To include any prospectus  required by Section  10(a)(3)
          of the Securities Act of 1933, as amended (the "Securities Act");

                    (ii) To  reflect  in the  prospectus  any  facts  or  events
          arising after the effective  date of this  Registration  Statement (or
          the most recent post-effective amendment thereof) which,  individually
          or in the aggregate, represent a fundamental change in the information
          set forth in this Registration Statement; and

                    (iii) To include any  material  information  with respect to
          the plan of distribution not previously disclosed in this Registration
          Statement  or  any  material  change  to  such   information  in  this
          Registration Statement;

          provided, however, that paragraphs (i) and (ii) shall not apply if the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs is contained in periodic reports filed by the Registrant  pursuant to
Section  13 or  Section  15(d) of the  Exchange  Act that  are  incorporated  by
reference in this Registration Statement;

          (2) For the purpose of determining  any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

     (b)  The  Registrant  hereby  further  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  Annual  Report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act that is  incorporated  by reference in the  Registration  Statement
shall be deemed to be a new  registration  statement  relating to the securities
offered  therein,  and the  offering  of such  securities  at that time shall be
deemed to be the initial bona fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the Registrant's bylaws, or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange  Commission such
indemnification  is against public policy as expressed in the Securities Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.
