   ITEM 5.           Interests of Named Experts and Counsel.

                     Not applicable.


   ITEM 6.           Indemnification of Directors and Officers.

         (a)  Limitation of Liability of Directors and Officers.  Section 102 of
         the Delaware  General  Corporation Law permits a corporation to provide
         in its  Certificate of  Incorporation  that a director or officer shall
         not be personally  liable to the  corporation or its  shareholders  for
         breach of any duty owed to the corporation or its shareholders,  except
         that such  provisions  shall not  relieve a director  or  officer  from
         liability  for any breach of duty based upon an action or omission  (a)
         in breach of such  person's duty of loyalty to the  corporation  or its
         shareholders, (b) not in good faith or involving intentional misconduct
         or a knowing  violation of law, (c)  involving  the payment of unlawful
         dividends  or  expenditure  of funds for  unlawful  stock  purchases or
         redemptions, or (d) resulting in receipt by such person of any improper
         personal  benefit.  Article  EIGHTH  of the  Company's  Certificate  of
         Incorporation  includes  limitation  on the  liability  of officers and
         directors to the fullest extent permitted by Delaware law.

         (b) Indemnification of Directors, Officers, Employees and Agents. Under
         Article TENTH of its  Certificate of  Incorporation,  the Company shall
         indemnify  and advance  expenses to its  directors  and officers to the
         fullest  extent  permitted  by the  Company's  Bylaws and the  Delaware
         General  Corporation Law. Article VIII of the Company's Bylaws provides
         that a director or officer shall be  indemnified  to the fullest extent
         permitted under the Delaware  General  Corporation  Law. Section 145 of
         the Delaware  General  Corporation  Law provides that a corporation may
         indemnify  its  directors,   officers,  employees  and  agents  against
         judgments,  fines, penalties,  amounts paid in settlement and expenses,
         including  attorneys'  fees,  resulting  from  various  types  of legal
         actions or  proceedings  if the actions of the party being  indemnified
         meet  the  standards  of  conduct  specified  therein.   Determinations
         concerning  whether or not the applicable  standard of conduct has been
         met  can be  made  by (a) a  disinterested  majority  of the  Board  of
         Directors, (b) independent legal counsel, or (c) an affirmative vote of
         a majority of shares held by the shareholders.  No  indemnification  is
         permitted to be made to or on behalf of a corporate director,  officer,
         employee or agent if a judgment or other final adjudication  adverse to
         such person  establishes  that his acts or omissions (a) were in breach
         of his duty of loyalty to the corporation or its shareholders, (b) were
         not in  good  faith  or  involved  a  knowing  violation  of law or (c)
         resulted in receipt by such person of an improper personal benefit.

                  Pursuant  to  Section   102(b)(7)  of  the  Delaware   General
         Corporation  Law,   Article  EIGHTH,   Paragraph  9  of  the  Company's
         Certificate of  Incorporation  provides that no director of the Company
         shall be liable to the Company or its stockholders for monetary damages
         for breach of fiduciary  duty as a director,  except for  liability (i)
         for any breach of the director's  duty of loyalty to the Company 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 Delaware General  Corporation Law, or (iv) for
         any transaction  from which the director  derived an improper  personal
         benefit.


   ITEM 7.           Exemption from Registration Claimed.

                     Not applicable.

   ITEM 8.           Exhibits.

        5      Opinion of Pitney,  Hardin,  Kipp & Szuch,  as to the legality of
               the securities being registered.

        23(a)  Consent of Arthur Andersen LLP.

        23(b)  Consent of Pitney,  Hardin,  Kipp & Szuch  (included in Exhibit 5
               hereto).

        24     Power of Attorney (included on signature page hereto).

        99     1999 Long-Term Incentive Plan.

   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 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.

            (b)      That, for purposes 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.

            (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 of 1933, each filing
         of the Registrant's annual report pursuant to Section 13(a) or 15(d) of
         the Securities  Exchange Act of 1934 that is  incorporated by reference
         in this 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 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 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 Act
         and will be governed by the final adjudication of such issue.

   ITEM 5.           Interests of Named Experts and Counsel.

                     Not applicable.

   ITEM 6.           Indemnification of Directors and Officers.

         (a)  Limitation of Liability of Directors and Officers.  Section 102 of
         the Delaware  General  Corporation Law permits a corporation to provide
         in its  Certificate of  Incorporation  that a director or officer shall
         not be personally  liable to the  corporation or its  shareholders  for
         breach of any duty owed to the corporation or its shareholders,  except
         that such  provisions  shall not  relieve a director  or  officer  from
         liability  for any breach of duty based upon an action or omission  (a)
         in breach of such  person's duty of loyalty to the  corporation  or its
         shareholders, (b) not in good faith or involving intentional misconduct
         or a knowing  violation of law, (c)  involving  the payment of unlawful
         dividends  or  expenditure  of funds for  unlawful  stock  purchases or
         redemptions, or (d) resulting in receipt by such person of any improper
         personal  benefit.  Article  EIGHTH  of the  Company's  Certificate  of
         Incorporation  includes  limitation  on the  liability  of officers and
         directors to the fullest extent permitted by Delaware law.

         (b) Indemnification of Directors, Officers, Employees and Agents. Under
         Article TENTH of its  Certificate of  Incorporation,  the Company shall
         indemnify  and advance  expenses to its  directors  and officers to the
         fullest  extent  permitted  by the  Company's  Bylaws and the  Delaware
         General  Corporation Law. Article VIII of the Company's Bylaws provides
         that a director or officer shall be  indemnified  to the fullest extent
         permitted under the Delaware  General  Corporation  Law. Section 145 of
         the Delaware  General  Corporation  Law provides that a corporation may
         indemnify  its  directors,   officers,  employees  and  agents  against
         judgments,  fines, penalties,  amounts paid in settlement and expenses,
         including  attorneys'  fees,  resulting  from  various  types  of legal
         actions or  proceedings  if the actions of the party being  indemnified
         meet  the  standards  of  conduct  specified  therein.   Determinations
         concerning  whether or not the applicable  standard of conduct has been
         met  can be  made  by (a) a  disinterested  majority  of the  Board  of
         Directors, (b) independent legal counsel, or (c) an affirmative vote of
         a majority of shares held by the shareholders.  No  indemnification  is
         permitted to be made to or on behalf of a corporate director,  officer,
         employee or agent if a judgment or other final adjudication  adverse to
         such person  establishes  that his acts or omissions (a) were in breach
         of his duty of loyalty to the corporation or its shareholders, (b) were
         not in  good  faith  or  involved  a  knowing  violation  of law or (c)
         resulted in receipt by such person of an improper personal benefit.

                  Pursuant  to  Section   102(b)(7)  of  the  Delaware   General
         Corporation  Law,   Article  EIGHTH,   Paragraph  9  of  the  Company's
         Certificate of  Incorporation  provides that no director of the Company
         shall be liable to the Company or its stockholders for monetary damages
         for breach of fiduciary  duty as a director,  except for  liability (i)
         for any breach of the director's  duty of loyalty to the Company 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 Delaware General  Corporation Law, or (iv) for
         any transaction  from which the director  derived an improper  personal
         benefit.

   ITEM 7.           Exemption from Registration Claimed.

                     Not applicable.

   ITEM 8.           Exhibits.

        5      Opinion of Pitney,  Hardin,  Kipp & Szuch,  as to the legality of
               the securities being registered.

        23(a)  Consent of Arthur Andersen LLP.

        23(b)  Consent of Pitney,  Hardin,  Kipp & Szuch  (included in Exhibit 5
               hereto).

        24     Power of Attorney (included on signature page hereto).

        99     1999 Long-Term Incentive Plan.

   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 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.

            (b)      That, for purposes 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.

            (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 of 1933, each filing
         of the Registrant's annual report pursuant to Section 13(a) or 15(d) of
         the Securities  Exchange Act of 1934 that is  incorporated by reference
         in this 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 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 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 Act
         and will be governed by the final adjudication of such issue.
