Item 5.  Interests of Named Experts and Counsel

Item 6.  Indemnification of Directors and Officers

     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its Directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act of 1933, as amended (the "Securities Act").

     The Registrant's Certificate of Incorporation and Bylaws include provisions
to (i) eliminate the personal liability of its directors for monetary damages
resulting from breaches of their fiduciary duty to the extent permitted by
Section 102(b)(7) of the General Corporation Law of Delaware (the "Delaware
Law") and (ii) require the Registrant to indemnify its Directors and officers to
the fullest extent permitted by Section 145 of the Delaware Law, including
circumstances in which indemnification is otherwise discretionary. Pursuant to
Section 145 of the Delaware Law, a corporation generally has the power to
indemnify its present and former directors, officers, employees and agents
against expenses incurred by them in connection with any suit to which they are,
or are threatened to be made, a party by reason of their serving in such
positions so long as 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, they had no reasonable cause to believe
their conduct was unlawful. The Registrant believes that these provisions are
necessary to attract and retain qualified persons as Directors and officers.
These provisions do not eliminate the Directors' duty of care, and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Delaware Law. In addition,
each Director will continue to be subject to liability for breach of the
Director's duty of loyalty to the Registrant, for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
acts or omissions that the Director believes to be contrary to the best
interests of the Registrant or its stockholders, for any transaction from which
the Director derived an improper personal benefit, for acts or omissions
involving a reckless disregard for the Director's duty to the Registrant or its
stockholders when the Director was aware or should have been aware of a risk of
serious injury to the Registrant or its stockholders, for acts or omissions that
constitute an unexcused pattern of inattention that amounts to an abdication of
the Director's duty to the Registrant or its stockholders, for improper
transactions between the Director and the Registrant and for improper
distributions to stockholders and loans to Directors and officers. The provision
also does not affect a Director's responsibilities under any other law, such as
the federal securities law or state or federal environmental laws.

     The Registrant has entered into indemnity agreements with each of its
Directors and certain executive officers that require the Registrant to
indemnify such persons against expenses, judgments, fines, settlements and other
amounts incurred (including expenses of a derivative action) in connection with
any proceeding, whether actual or threatened, to which any such person may be
made a party by reason of the fact that such person is or was a Director or an
executive officer of the Registrant or any of its affiliated enterprises,
provided that 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
Registrant and, with respect to any criminal proceeding, had no reasonable cause
to believe his conduct was unlawful. The indemnification agreements also set
forth certain procedures that will apply in the event of a claim for
indemnification thereunder.

     At present, there is no pending litigation or proceeding involving a
Director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or Director.

     The Registrant has an insurance policy covering the officers and Directors
of the Registrant with respect to certain liabilities, including liabilities
arising under the Securities Act or otherwise.

Item 9.  Undertakings

1.   The undersigned 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:

          (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 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) (ss. 230.424(b) of this chapter) if, in the
     aggregate, the changes in volume and price represent no more than a 20%
     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)(i) and (a)(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 issuer pursuant to
section 13 or section 15(d) of the Exchange Act that are incorporated by
reference herein.
<PAGE>

     (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 herein, 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.

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 Section 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 herein,
     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 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

     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its Directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act of 1933, as amended (the "Securities Act").

     The Registrant's Certificate of Incorporation and Bylaws include provisions
to (i) eliminate the personal liability of its directors for monetary damages
resulting from breaches of their fiduciary duty to the extent permitted by
Section 102(b)(7) of the General Corporation Law of Delaware (the "Delaware
Law") and (ii) require the Registrant to indemnify its Directors and officers to
the fullest extent permitted by Section 145 of the Delaware Law, including
circumstances in which indemnification is otherwise discretionary. Pursuant to
Section 145 of the Delaware Law, a corporation generally has the power to
indemnify its present and former directors, officers, employees and agents
against expenses incurred by them in connection with any suit to which they are,
or are threatened to be made, a party by reason of their serving in such
positions so long as 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, they had no reasonable cause to believe
their conduct was unlawful. The Registrant believes that these provisions are
necessary to attract and retain qualified persons as Directors and officers.
These provisions do not eliminate the Directors' duty of care, and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of non-monetary relief will remain available under Delaware Law. In addition,
each Director will continue to be subject to liability for breach of the
Director's duty of loyalty to the Registrant, for acts or omissions not in good
faith or involving intentional misconduct, for knowing violations of law, for
acts or omissions that the Director believes to be contrary to the best
interests of the Registrant or its stockholders, for any transaction from which
the Director derived an improper personal benefit, for acts or omissions
involving a reckless disregard for the Director's duty to the Registrant or its
stockholders when the Director was aware or should have been aware of a risk of
serious injury to the Registrant or its stockholders, for acts or omissions that
constitute an unexcused pattern of inattention that amounts to an abdication of
the Director's duty to the Registrant or its stockholders, for improper
transactions between the Director and the Registrant and for improper
distributions to stockholders and loans to Directors and officers. The provision
also does not affect a Director's responsibilities under any other law, such as
the federal securities law or state or federal environmental laws.

     The Registrant has entered into indemnity agreements with each of its
Directors and certain executive officers that require the Registrant to
indemnify such persons against expenses, judgments, fines, settlements and other
amounts incurred (including expenses of a derivative action) in connection with
any proceeding, whether actual or threatened, to which any such person may be
made a party by reason of the fact that such person is or was a Director or an
executive officer of the Registrant or any of its affiliated enterprises,
provided that 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
Registrant and, with respect to any criminal proceeding, had no reasonable cause
to believe his conduct was unlawful. The indemnification agreements also set
forth certain procedures that will apply in the event of a claim for
indemnification thereunder.

     At present, there is no pending litigation or proceeding involving a
Director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or Director.

     The Registrant has an insurance policy covering the officers and Directors
of the Registrant with respect to certain liabilities, including liabilities
arising under the Securities Act or otherwise.

     pursuant to Rule 424(b) (ss. 230.424(b) of this chapter) if, in the
     aggregate, the changes in volume and price represent no more than a 20%
     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)(i) and (a)(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 issuer pursuant to
section 13 or section 15(d) of the Exchange Act that are incorporated by
reference herein.
(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 herein, 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.

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 Section 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 herein,
     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 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.
