ITEM 4.      DESCRIPTION OF SECURITIES.

                Not applicable.

ITEM 5.      INTERESTS OF NAMED EXPERTS AND COUNSEL.

                Not applicable.

ITEM 6.      INDEMNIFICATION OF DIRECTORS AND OFFICERS.

                As more fully described below, Section 145 of the General
Corporation Law of the State of Delaware (the "DGCL") permits Delaware
corporations to indemnify each of their present and former directors or officers
under certain circumstances, provided that such persons acted in good faith and
in a manner which they reasonably believed to be in, or not opposed to, the best
interests of the corporation. Article III of our Amended and Restated Bylaws
provides that we will indemnify, to the fullest extent permitted by Section 145
of the DGCL, as the same may be amended from time to time, all persons whom we
may indemnify pursuant thereto and in the manner prescribed thereby.

<PAGE>
                Specifically, Section 145 of the DGCL 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 the
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, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by the person in
connection with such action, suit or proceeding if the person acted in good
faith and in a manner the 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 the person's conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which the 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 reasonable cause to believe that the person's
conduct was unlawful.

                Section 145 of the DGCL also 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 or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that the
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 against expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense or settlement
of such action or suit if the person acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
corporation and 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 Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the 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.

                Any such indemnification (unless ordered by a court) shall be
made by the corporation only as authorized in the specific case upon a
determination that indemnification of the present or former director, officer,
employee or agent is proper in the circumstances because the person has met the
applicable standard of conduct set forth above.

                Section 145 of the DGCL permits a Delaware corporation to
purchase and maintain insurance on behalf of any person who 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 any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether or
not the corporation would have the power to indemnify such person against such
liability.

                Section 102(b) of the DGCL enables a Delaware corporation to
include a provision in its certificate of incorporation eliminating or limiting
the personal liability of a director to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director. Our certificate of
incorporation contains provisions that limit the personal liability of each of
our directors to us and our stockholders for monetary damages for breach of
fiduciary duty as a director. These provisions eliminate personal liability to
the fullest extent permitted by the DGCL.

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;

               (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


<PAGE>
                    Statement. Notwithstanding the foregoing, any increase or
                    decrease in the 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
                    end of the estimated maximum offering range may be 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 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 paragraph (a)(1)(i) and (a)(1)(ii) do not apply if
     the information required to be included in a post-effective amendment by
     the foregoing paragraphs is contained in periodic reports filed with or
     furnished to the Commission by the Registrant pursuant to Section 13 or
     Section 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.

(b)  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 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 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.

                As more fully described below, Section 145 of the General
Corporation Law of the State of Delaware (the "DGCL") permits Delaware
corporations to indemnify each of their present and former directors or officers
under certain circumstances, provided that such persons acted in good faith and
in a manner which they reasonably believed to be in, or not opposed to, the best
interests of the corporation. Article III of our Amended and Restated Bylaws
provides that we will indemnify, to the fullest extent permitted by Section 145
of the DGCL, as the same may be amended from time to time, all persons whom we
may indemnify pursuant thereto and in the manner prescribed thereby.
Specifically, Section 145 of the DGCL 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 the
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, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by the person in
connection with such action, suit or proceeding if the person acted in good
faith and in a manner the 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 the person's conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which the 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 reasonable cause to believe that the person's
conduct was unlawful.

                Section 145 of the DGCL also 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 or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that the
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 against expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense or settlement
of such action or suit if the person acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
corporation and 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 Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the 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.

                Any such indemnification (unless ordered by a court) shall be
made by the corporation only as authorized in the specific case upon a
determination that indemnification of the present or former director, officer,
employee or agent is proper in the circumstances because the person has met the
applicable standard of conduct set forth above.

                Section 145 of the DGCL permits a Delaware corporation to
purchase and maintain insurance on behalf of any person who 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 any liability asserted against such person and incurred by such person
in any such capacity, or arising out of such person's status as such, whether or
not the corporation would have the power to indemnify such person against such
liability.

                Section 102(b) of the DGCL enables a Delaware corporation to
include a provision in its certificate of incorporation eliminating or limiting
the personal liability of a director to the corporation or its stockholders for
monetary damages for breach of fiduciary duty as a director. Our certificate of
incorporation contains provisions that limit the personal liability of each of
our directors to us and our stockholders for monetary damages for breach of
fiduciary duty as a director. These provisions eliminate personal liability to
the fullest extent permitted by the DGCL.

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;

               (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 the 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
                    end of the estimated maximum offering range may be 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 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 paragraph (a)(1)(i) and (a)(1)(ii) do not apply if
     the information required to be included in a post-effective amendment by
     the foregoing paragraphs is contained in periodic reports filed with or
     furnished to the Commission by the Registrant pursuant to Section 13 or
     Section 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.

(b)  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 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 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.
