ITEM 4.  DESCRIPTION OF SECURITIES.

          Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

          Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          The Delaware General Corporation Law (the "DGCL") authorizes
corporations to limit or eliminate the personal liability of directors to the
corporation and its stockholders for monetary damages in connection with the
breach of a director's fiduciary duty of care.  The duty of care requires that,
when acting on behalf of the corporation, directors must exercise an informed
business judgment based on all material information reasonably available to
them. Absent the limitation authorized by the DGCL, directors could be
accountable to corporations and their stockholders for monetary damages for
conduct that does not satisfy such duty of care. Although the DGCL does not
change a director's duty of care, it enables corporations to limit available
relief to equitable remedies such as injunction or rescission.  The Registrant's
certificate of incorporation limits the liability of directors to the Registrant
or its stockholders to the fullest extent permitted by the DGCL as in effect
from time to time.  Specifically, directors of the Registrant will not be
personally liable for monetary damages for breach of a fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or to its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which
the director derives any improper personal benefit.

          The bylaws of the Registrant provide that the Registrant shall
indemnify its officers, directors and employees to the fullest extent permitted
by the DGCL.  The Registrant believes that indemnification under its bylaws
covers at least negligence and gross negligence on the part of the indemnified
parties.

          The Registrant has entered into an agreement with each of its
directors and certain of its officers indemnifying them to the fullest extent
permitted by the foregoing.  The Company has also purchased director and officer
liability insurance.

ITEM 9.   UNDERTAKINGS.

          (a) 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 of 1933;

                    (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.
               Notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the total dollar value of securities
               offered would not exceed that which was registered) and any
               deviation from the low or high and of the estimated maximum
               offering range may be 

                                       3
<PAGE>
 
               reflected in the form of prospectus filed with the Commission
               pursuant to Rule 424(b) if, in the aggregate, the changes in
               volume and price represent no more than 20 percent change in the
               maximum aggregate offering price set forth in the "Calculation of
               Registration Fee" table in the effective registration statement.

                    (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 (a)(1)(i) and (a)(1)(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 by the Registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference in the Registration Statement.

               (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, 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 undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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 of 1933 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 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.

ITEM 4.  DESCRIPTION OF SECURITIES.

          Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

          Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          The Delaware General Corporation Law (the "DGCL") authorizes
corporations to limit or eliminate the personal liability of directors to the
corporation and its stockholders for monetary damages in connection with the
breach of a director's fiduciary duty of care.  The duty of care requires that,
when acting on behalf of the corporation, directors must exercise an informed
business judgment based on all material information reasonably available to
them. Absent the limitation authorized by the DGCL, directors could be
accountable to corporations and their stockholders for monetary damages for
conduct that does not satisfy such duty of care. Although the DGCL does not
change a director's duty of care, it enables corporations to limit available
relief to equitable remedies such as injunction or rescission.  The Registrant's
certificate of incorporation limits the liability of directors to the Registrant
or its stockholders to the fullest extent permitted by the DGCL as in effect
from time to time.  Specifically, directors of the Registrant will not be
personally liable for monetary damages for breach of a fiduciary duty as a
director, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or to its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the DGCL or (iv) for any transaction from which
the director derives any improper personal benefit.

          The bylaws of the Registrant provide that the Registrant shall
indemnify its officers, directors and employees to the fullest extent permitted
by the DGCL.  The Registrant believes that indemnification under its bylaws
covers at least negligence and gross negligence on the part of the indemnified
parties.

          The Registrant has entered into an agreement with each of its
directors and certain of its officers indemnifying them to the fullest extent
permitted by the foregoing.  The Company has also purchased director and officer
liability insurance.

ITEM 9.   UNDERTAKINGS.

          (a) 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 of 1933;

                    (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.
               Notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the total dollar value of securities
               offered would not exceed that which was registered) and any
               deviation from the low or high and of the estimated maximum
               offering range may be 

                                       3
reflected in the form of prospectus filed with the Commission
               pursuant to Rule 424(b) if, in the aggregate, the changes in
               volume and price represent no more than 20 percent change in the
               maximum aggregate offering price set forth in the "Calculation of
               Registration Fee" table in the effective registration statement.

                    (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 (a)(1)(i) and (a)(1)(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 by the Registrant
     pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of
     1934 that are incorporated by reference in the Registration Statement.

               (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, 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 undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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 of 1933 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 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.
