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

     The following documents, which are filed with the Securities and Exchange
Commission (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 Securities Exchange Act of 1934, as amended (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 by the Registrant pursuant to Section
     13(a) or 15(d) of the Exchange Act since the end of the fiscal year covered
     by the annual report or the prospectus referred to in (1) above.

Item 4.  Description of Securities
         -------------------------

         Not applicable.

Item 5.  Interests of Named Experts and Counsel
         --------------------------------------

     The validity of the shares of Common Stock offered hereby will be
passed upon for the Company by Hale and Dorr LLP, Boston, Massachusetts.  A
partner of Hale and Dorr LLP owns 7,500 shares of the Company's Common Stock.

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

     Section 145 of the Delaware General Corporation Law ("DGCL"), empowers a
Delaware corporation to indemnify any persons who are or are threatened to be
made, parties 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 such
person 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. The indemnity may include expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding if
such person acted in good faith and in a manner such person 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. A Delaware corporation may indemnify directors,
officers, employees or agents of the corporation, in an action by or in the
right of the corporation under the same conditions, except that no
indemnification is permitted without judicial approval if a director, officer,
employee or agent of the corporation is adjudged to be liable to the corporation
in the performance of such person's duty. Where a director, officer, employee or
agent of the corporation is successful on the merits or otherwise in the defense
of any action referred to above, the corporation must indemnify such person
against the expenses actually and reasonably incurred by such person.

     The Registrant's Certificate of Incorporation, as amended (the
"Certificate"), provides that no director of the Registrant shall be personally
liable to the Registrant or its stockholders for monetary damages for any breach
of fiduciary duty as a director, except to the extent the DGCL prohibits such
indemnification.  The Certificate also provides for indemnification of 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 (including an action by or in the
right of the Registrant), by reason of such person's position, or by reason of
any action alleged to have been taken or omitted in such person's capacity, if
such person acted in good faith and in a manner he or she reasonably believed to

                                       3
<PAGE>
 
be in, or not opposed to, the best interests of the Registrant.  In addition,
the Registrant maintains insurance policies which provide coverage for its
officers and directors in certain situations where the Registrant cannot
directly indemnify such officers or directors.

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

         Not applicable.
 
Item 8.  Exhibits
         ---------------

     The following exhibits are filed as part of this Registration Statement:

     4.1  Certificate of Incorporation of the Registrant, as amended.
          Incorporated by reference to Exhibit 3.1 to the Registrant's
          Registration Statement on Form S-1 (File No. 333-64233).

     4.2  By-Laws of the Registrant, as amended.  Incorporated by
          reference to Exhibit 3.2 to the Registrant's Registration
          Statement on Form S-1 (File No. 333-64233).

     5.1  Opinion of Hale and Dorr LLP.

    23.1  Consent of Hale and Dorr LLP (included in Exhibit 5.1).

    23.2  Consent of PricewaterhouseCoopers LLP.

    24    Power of Attorney (included in the signature page of this
          Registration Statement).

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

     1.  The Registrant hereby undertakes (a) to file, during any period in
which offers or sales are being made, a post-effective amendment to this
Registration Statement 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; (b)
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; (c) 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.

                                       4
<PAGE>
 
     2. The undersigned Registrant hereby 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 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.
