            that 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 securities offered have been
sold or which deregisters all securities then remaining unsold, shall be deemed
to be incorporated by reference herein and to be a part hereof from the date of
filing of such documents. Any statement contained in a document incorporated or
deemed to be incorporated by

                                      II-1

<PAGE>

reference herein shall be deemed to be modified or superseded for purposes of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 incorporated or deemed to
be incorporated by reference herein modifies or supersedes such statement. Any
such statement so modified or superseded shall not be deemed, except as so
modified or superseded, to constitute a part of this registration statement.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

         None.

Item 6.           Indemnification of Directors and Officers

     Article 6 of the Registrant's Restated Certificate of Incorporation, in
accordance with Section 145 of the DGCL, provides that directors and officers
shall be indemnified against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement in connection with specified actions, suits
or proceedings, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation -- a "derivative action")
if they acted in good faith and in a manner they 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 their conduct
was unlawful. A similar standard of care is applicable in the case of derivative
actions, except that indemnification only extends to expenses (including
attorneys' fees) incurred in connection with the defense or settlement of such
an action. Moreover, the DGCL requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation.

         Article 6 of the Registrant's Restated Certificate of Incorporation
further provides that directors and officers are entitled to be paid by the
Registrant the expenses incurred in defending the proceedings specified above in
advance of their final disposition, provided that such payment will only be made
upon delivery to the Registrant by the indemnified party of an undertaking to
repay all amounts so advanced if it is ultimately determined that the person
receiving such payments is not entitled to be indemnified.

         Article 6 of the Registrant's Restated Certificate of Incorporation
provides that a person indemnified under Article 6 of the Certificate of
Incorporation may contest any determination that a director, officer, employee
or agent has not met the applicable standard of conduct set forth in the
Restated Certificate of Incorporation by petitioning a court of competent
jurisdiction.

         Article 6 of the Registrant's Restated Certificate of Incorporation

                                      II-2

<PAGE>

provides that the right to indemnification and the payment of expenses incurred
in defending a proceeding in advance of its final disposition conferred in the
Article will not be exclusive of any other right which any person may have or
acquire under the Restated Certificate of Incorporation, or any statute or
agreement, or otherwise.

         Finally, Article 6 of the Registrant's Restated Certificate of
Incorporation provides that the Registrant may maintain insurance, at its
expense, to reimburse itself and directors and officers of the Registrant and of
its direct and indirect subsidiaries against any expense, liability or loss,
whether or not the Registrant would have the power to indemnify such persons
against such expense, liability or loss under the provisions of Article 6 of the
Restated Certificate of Incorporation.

         Article 7 of the Registrant's Restated Certificate of Incorporation
eliminates the personal liability of the Registrant's directors to the
Registrant or its stockholders for monetary damages for breach of their
fiduciary duties as a director to the fullest extent provided by Delaware law.
Section 102(b)(7) of the DGCL provides for the elimination off such personal
liability, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or 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 derived any improper personal benefit.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is therefore unenforceable.

Item 7.           Exemption From Registration Claimed.

         Not applicable.

Item 9.           Undertakings.

         (a)      The undersigned Registrant hereby undertakes that it will:

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

                           (i) Include any prospectus required by Section 10 (a)
(3) of the Securities Act of 1933;

                           (ii) 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, represents a fundamental change in the information set forth in the
Registration Statement;

                           (iii) 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
Registration Statement is on Form S-3 or Form S-8 and 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) 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; and

                  (3) 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 or controlling
persons of the Registrant pursuant to any arrangement, provision 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 of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses

                                      II-4

<PAGE>

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 of 1933 and will be governed by the
final adjudication of such issue.

         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 securities offered have been

to be incorporated by reference herein and to be a part hereof from the date of
filing of such documents. Any statement contained in a document incorporated or
deemed to be incorporated by

                                      II-1
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 incorporated or deemed to
be incorporated by reference herein modifies or supersedes such statement. Any
such 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

         None.

Item 6.           Indemnification of Directors and Officers

     Article 6 of the Registrant's Restated Certificate of Incorporation, in
accordance with Section 145 of the DGCL, provides that directors and officers
shall be indemnified against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement in connection with specified actions, suits
or proceedings, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation -- a "derivative action")
if they acted in good faith and in a manner they 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 their conduct
was unlawful. A similar standard of care is applicable in the case of derivative
actions, except that indemnification only extends to expenses (including
attorneys' fees) incurred in connection with the defense or settlement of such
an action. Moreover, the DGCL requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation.

         Article 6 of the Registrant's Restated Certificate of Incorporation
further provides that directors and officers are entitled to be paid by the
Registrant the expenses incurred in defending the proceedings specified above in
advance of their final disposition, provided that such payment will only be made
upon delivery to the Registrant by the indemnified party of an undertaking to
repay all amounts so advanced if it is ultimately determined that the person
receiving such payments is not entitled to be indemnified.

         Article 6 of the Registrant's Restated Certificate of Incorporation
provides that a person indemnified under Article 6 of the Certificate of
Incorporation may contest any determination that a director, officer, employee
or agent has not met the applicable standard of conduct set forth in the
Restated Certificate of Incorporation by petitioning a court of competent
jurisdiction.

         Article 6 of the Registrant's Restated Certificate of Incorporation

                                      II-2
provides that the right to indemnification and the payment of expenses incurred
in defending a proceeding in advance of its final disposition conferred in the
Article will not be exclusive of any other right which any person may have or
acquire under the Restated Certificate of Incorporation, or any statute or
agreement, or otherwise.

         Finally, Article 6 of the Registrant's Restated Certificate of
Incorporation provides that the Registrant may maintain insurance, at its
expense, to reimburse itself and directors and officers of the Registrant and of
its direct and indirect subsidiaries against any expense, liability or loss,
whether or not the Registrant would have the power to indemnify such persons
against such expense, liability or loss under the provisions of Article 6 of the
Restated Certificate of Incorporation.

         Article 7 of the Registrant's Restated Certificate of Incorporation
eliminates the personal liability of the Registrant's directors to the
Registrant or its stockholders for monetary damages for breach of their
fiduciary duties as a director to the fullest extent provided by Delaware law.
Section 102(b)(7) of the DGCL provides for the elimination off such personal
liability, except for liability (i) for any breach of the director's duty of
loyalty to the Registrant or 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 derived any improper personal benefit.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or persons controlling the
Registrant pursuant to the foregoing provisions, the Registrant has been
informed that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is therefore unenforceable.

Item 7.           Exemption From Registration Claimed.

         Not applicable.

                           Exhibit 5.1 hereto).

Item 9.           Undertakings.

         (a)      The undersigned Registrant hereby undertakes that it will:

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

                           (i) Include any prospectus required by Section 10 (a)
(3) of the Securities Act of 1933;

                           (ii) 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, represents a fundamental change in the information set forth in the
Registration Statement;

                           (iii) 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
Registration Statement is on Form S-3 or Form S-8 and 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) 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; and

                  (3) 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 or controlling
persons of the Registrant pursuant to any arrangement, provision 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 of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses

                                      II-4
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 of 1933 and will be governed by the
final adjudication of such issue.
