PART I.  INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

          The information required by Part I is included in documents sent or
given to participants in the Registrant's 1996 Employee Stock Purchase Plan, as
amended (the "Plan") pursuant to Rule 428(b)(1) of the Securities Act of 1933,
as amended (the "Securities Act").

PART II.  INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

     Item 3.  Incorporation of Documents by Reference
              ---------------------------------------

          The Registrant is subject to the informational and reporting
requirements of Sections 13(a), 14 and 15(d) of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and in accordance therewith files
reports, proxy statements and other information with the Securities and Exchange
Commission (the "Commission").  The following documents, which are on file with
the Commission, are incorporated in this Registration Statement by reference:

          (1) The Registrant's latest annual report filed pursuant to Section
     13(a) or 15(d) of the Exchange Act, or the latest prospectus filed pursuant
     to Rule 424(b) under the Securities Act that contains audited financial
     statements for the Registrant's latest fiscal year for which such
     statements have been filed.

          (2) All other reports filed pursuant to Section 13(a) or 15(d) of the
     Exchange Act since the end of the fiscal year covered by the document
     referred to in (1) above.

          (3) The description of the common stock of the Registrant, $.01 par
     value per share (the "Common Stock"), contained in the Registration
     Statement on Form 8-A filed by the Registrant with the Commission on May 3,
     1996, including any amendment or report filed for the purpose of updating
     such description.

          All documents subsequently filed by the Registrant pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of
a post-effective amendment which indicates that all shares of Common Stock
offered hereby have been sold or which deregisters all shares of Common Stock
then remaining unsold, shall be deemed to be incorporated by reference herein
and to be part hereof from the date of the filing of such documents.  Any
statement contained 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reference herein shall be deemed to be modified or superseded for purposes of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 legality of the Common Stock being offered hereby will be passed
upon for the Company by Hale and Dorr LLP, Boston, Massachusetts.

     Item 6.  Indemnification of Directors and Officers
              -----------------------------------------

          Article EIGHTH of the Registrant's Amended and Restated Certificate of
Incorporation, as amended (the "Certificate of Incorporation") provides that no
director of the Registrant shall be personally liable for any monetary damages
for any breach of fiduciary duty as a director, except to the extent that the
Delaware General Corporation Law prohibits the elimination of liability of
directors for breaches of fiduciary duty.

          Article NINTH of the Certificate of Incorporation provides that a
director or officer of the Registrant (a) shall be indemnified by the Registrant
against all expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred in connection with any
litigation or other legal proceeding (other than an action by or in the right of
the Registrant) brought against him by virtue of his position as a director or
officer of the Registrant if he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of the
Registrant, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful and (b) shall be
indemnified by the Registrant against all expenses (including attorneys' fees)
and amounts paid in settlement actually and reasonably incurred in connection
with any action by or in the right of the Registrant brought against him by
virtue of his position as a director or officer of the Registrant if he acted in
good faith and in a manner he reasonably believed to be in, or not opposed to,
the best interests of the Registrant, except that no indemnification shall be
made with respect to any matter as to which such person shall have been adjudged
to be liable to the Registrant, unless the Court of Chancery of Delaware
determines that, despite such adjudication but in view of all of the
circumstances, he is entitled to indemnification of such expenses.
Notwithstanding the foregoing, to the extent that a director or officer has been
successful, on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, he is required to be indemnified by
the Registrant against all expenses (including attorneys' fees) actually and
reasonably incurred in connection therewith. In the event the Registrant does
not assume the defense of an action in accordance with the Certificate of
Incorporation, expenses shall be advanced to a director or officer at his
request prior to the final disposition of the matter, provided that he
undertakes to repay the amount advanced if it is ultimately determined that he
is not entitled to indemnification for such expenses.

          Indemnification is required to be made unless the Registrant
determines that the applicable standard of conduct required for indemnification
has not been met and must be made if the director or officer was successful, on
the merits or otherwise,

                                      II-2
<PAGE>

in defense of the matter. In the event of a determination by the Registrant that
the director or officer did not meet the applicable standard of conduct required
for indemnification, or if the Registrant fails to make an indemnification
payment within 60 days after such payment is claimed by such person, such person
is permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification. As a condition precedent to
the right of indemnification, the director or officer must give the Registrant
notice of the action for which indemnity is sought, and the Registrant has the
right to participate in such action or assume the defense thereof.

          Article NINTH of the Certificate of Incorporation further provides
that the indemnification provided therein is not exclusive, and provides that in
the event that the Delaware General Corporation Law is amended to expand the
indemnification permitted to directors or officers the Registrant must indemnify
those persons to the fullest extent permitted by such law as so amended.

          Section 145 of the Delaware General Corporation Law, as amended,
provides that a corporation may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
Section 145 further provides that a corporation similarly may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Delaware Court of Chancery or the court
in which such action or suit was brought shall determine upon application that,
despite an adjudication of liability but in view of all the circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

     The Registrant has directors and officers liability insurance for the
benefit of its directors and officers.

     Item 7.  Exemption from Registration Claimed
              -----------------------------------

          Not applicable.

     Item 8.  Exhibits
              --------

          The Exhibit Index immediately preceding the exhibits is incorporated
herein by reference.

     Item 9.  Undertakings
              ------------

          1.   The undersigned 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;

                   (ii)   To reflect in the prospectus any facts or events
          arising after the effective date of the 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 the Registration Statement; and

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

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

               (2) That, 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.

          2.   The undersigned Registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the
Registrant's annual

                                      II-4
<PAGE>

report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
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.

          3.   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 foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the 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.
