                            Registrant's Current Report on Form 8-K filed with

Item 4.    Description of Securities

           Not Applicable.

Item 5.    Interests of Named Experts and Counsel

           Not Applicable.

Item 6.    Indemnification of Directors and Officers

           Section 145 of the Delaware General Corporation Law permits a
corporation to indemnify any of its directors or officers who was or is a party
or is threatened to be made a party to any third party proceeding by reason of
the fact that such person is or was a director or officer of the corporation
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, if 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 corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that such person's conduct was
unlawful. In a derivative action, i.e., one by or in the right of a corporation,
the corporation is permitted to indemnify any of its directors or officers
against expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection with the defense or settlement of such action or suit
if 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 corporation,
except that no indemnification shall be made if such person shall have been
adjudged liable to the corporation, unless and only to the extent that the court
in which such action or suit was brought shall determine upon application that
such person is fairly and reasonably entitled to indemnity for such expenses
despite such adjudication of liability.

           Article VII of the Registrant's currently effective Certificate of
Incorporation eliminates the personal liability of its directors 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 corporation 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. In addition, as permitted by
Section 145 of the Delaware General Corporation Law, the Bylaws of the
Registrant provide that: (a) the Registrant is required to indemnify its
directors and officers and persons serving in such capacities in other business
entities (including, for example, subsidiaries of the Registrant) at the
Registrant's request (such directors, officers and other persons are
collectively, "Covered Persons"), to the fullest extent permitted by Delaware
law, including those circumstances in which indemnification would otherwise be
discretionary; (b) the Registrant is required to advance expenses, as incurred
to such Covered Persons in connection with defending a proceeding; (c) the
indemnitee(s) of the Registrant have the right to bring suit, and to be paid the
expenses of prosecuting such suit if successful, to enforce the rights to
indemnification under the Bylaws or to advancement of expenses under the Bylaws;
(d) the rights conferred in the Bylaws are not exclusive and the Registrant is
authorized to enter into indemnification agreements with such directors,
officers and employees; (e) the Registrant is required to maintain director and
officer liability insurance to the extent reasonably available; and (f) the
Registrant may not retroactively amend the Bylaws indemnification provision in a
way that is adverse to such Covered Persons.

           The Registrant has entered into indemnity agreements with each of its
executive officers and directors that provide the maximum indemnity allowed to
officers and directors by Section 145 of the Delaware General Corporation Law
and the Bylaws, as well as certain additional procedural protections. The
Registrant also maintains a limited amount of director and officer insurance.
The indemnification provision in the Bylaws, and the indemnity agreements
entered into between the Registrant and its officers or directors, may be
sufficiently broad to permit indemnification of the Registrant's officers and
directors for liability arising under the Securities Act of 1933, as amended
(the "1933 Act").

Item 7.    Exemption from Registration Claimed

           Not Applicable.

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 1933 Act; (ii) to reflect in the prospectus any facts or events
arising after the effective date of this 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 this
Registration Statement; and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided however, that clauses (1)(i) and (l)(ii) shall
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 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 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, and
(3) to remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold upon the termination of the
offering under the Plans.

           B. Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnity provisions incorporated by reference in
Item 6, or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
1933 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 1933 Act and
will be governed by the final adjudication of such issue.

                     (a)    The Registrant's Annual Report on Form 10-K for the

                            Commission on August 29, 1990; and

                     (e)    The description of the Registrant's Preferred Share

                            Registrant's Current Report on Form 8-K filed with

Item 4.    Description of Securities

           Not Applicable.

Item 5.    Interests of Named Experts and Counsel

           Not Applicable.

Item 6.    Indemnification of Directors and Officers

           Section 145 of the Delaware General Corporation Law permits a
corporation to indemnify any of its directors or officers who was or is a party
or is threatened to be made a party to any third party proceeding by reason of
the fact that such person is or was a director or officer of the corporation
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding, if 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 corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that such person's conduct was
unlawful. In a derivative action, i.e., one by or in the right of a corporation,
the corporation is permitted to indemnify any of its directors or officers
against expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection with the defense or settlement of such action or suit
if 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 corporation,
except that no indemnification shall be made if such person shall have been
adjudged liable to the corporation, unless and only to the extent that the court
in which such action or suit was brought shall determine upon application that
such person is fairly and reasonably entitled to indemnity for such expenses
despite such adjudication of liability.

           Article VII of the Registrant's currently effective Certificate of
Incorporation eliminates the personal liability of its directors 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 corporation 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. In addition, as permitted by
Section 145 of the Delaware General Corporation Law, the Bylaws of the
Registrant provide that: (a) the Registrant is required to indemnify its
directors and officers and persons serving in such capacities in other business
entities (including, for example, subsidiaries of the Registrant) at the
Registrant's request (such directors, officers and other persons are
collectively, "Covered Persons"), to the fullest extent permitted by Delaware
law, including those circumstances in which indemnification would otherwise be
discretionary; (b) the Registrant is required to advance expenses, as incurred
to such Covered Persons in connection with defending a proceeding; (c) the
indemnitee(s) of the Registrant have the right to bring suit, and to be paid the
expenses of prosecuting such suit if successful, to enforce the rights to
indemnification under the Bylaws or to advancement of expenses under the Bylaws;
(d) the rights conferred in the Bylaws are not exclusive and the Registrant is
authorized to enter into indemnification agreements with such directors,
officers and employees; (e) the Registrant is required to maintain director and
officer liability insurance to the extent reasonably available; and (f) the
Registrant may not retroactively amend the Bylaws indemnification provision in a
way that is adverse to such Covered Persons.

           The Registrant has entered into indemnity agreements with each of its
executive officers and directors that provide the maximum indemnity allowed to
officers and directors by Section 145 of the Delaware General Corporation Law
and the Bylaws, as well as certain additional procedural protections. The
Registrant also maintains a limited amount of director and officer insurance.
The indemnification provision in the Bylaws, and the indemnity agreements
entered into between the Registrant and its officers or directors, may be
sufficiently broad to permit indemnification of the Registrant's officers and
directors for liability arising under the Securities Act of 1933, as amended
(the "1933 Act").

Item 7.    Exemption from Registration Claimed

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 1933 Act; (ii) to reflect in the prospectus any facts or events
arising after the effective date of this 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 this
Registration Statement; and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided however, that clauses (1)(i) and (l)(ii) shall
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 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 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, and
(3) to remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold upon the termination of the
offering under the Plans.

           B. Insofar as indemnification for liabilities arising under the 1933
Act may be permitted to directors, officers or controlling persons of the
Registrant pursuant to the indemnity provisions incorporated by reference in
Item 6, or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
1933 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 1933 Act and
will be governed by the final adjudication of such issue.
