(d)      The description of the Company's capital stock contained in the
         Company's Registration Statement on Form S-4 (File No. 33-64089),
         including any amendments or reports filed for the purpose of updating
         such description.

         All documents filed by the Company pursuant to Sections 13(a), 13(c),
14 and 15(d) of the Exchange Act, subsequent to the date hereof and prior to the
filing of a post-effective amendment which indicates that all securities offered
hereby have been sold or which deregisters all securities remaining unsold,

Item 4. DESCRIPTION OF SECURITIES.

         The Company's Common Stock is registered under Section 12 of the
Exchange Act.

Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

         William E. McDonald, Associate General Counsel and Deputy Secretary for
the Company, has provided an opinion as to the legality of the securities being
registered hereby. As a result of awards under stock-based compensation plans

Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law of the State of
Delaware ("DGCL") grants each corporation organized thereunder, such as the
Company, the power to indemnify its directors and officers against liability for
certain of their acts. Section 102(b)(7) of the DGCL permits a provision in the
certificate of incorporation of each corporation organized thereunder
eliminating or limiting, with certain exceptions, the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director. The Company's certificate of incorporation
contains such a provision. The foregoing statements are subject to the detailed
provisions of Sections 145 and 102(b)(7) of the DGCL.

         Article VI of the Company's Bylaws provides that the Company shall
indemnify its officers, directors and employees to the fullest extent permitted
by the DGCL in connection with proceedings with which any such person is
involved by virtue of his or her status as an officer, director or employee. The
Company has also by contract agreed to indemnify its directors against damages,
judgments, settlements and costs arising out of any actions


                                      II-1
<PAGE>

against the directors brought by reason of the fact that they are or were
directors. The Company maintains directors' and officers' liability insurance,
including a reimbursement policy in favor of the Company.

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 Securities Act of 1933;

                  (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 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 Securities and Exchange Commission
                           pursuant to Rule 424(b) 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(1)(i) and A(1)(ii) above will 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


                                      II-2
<PAGE>

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)      That, 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.

         (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 of 1933, 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 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
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 incurred or paid by a director, officer or other
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.

         such description.

         All documents filed by the Company pursuant to Sections 13(a), 13(c),

Item 4. DESCRIPTION OF SECURITIES.

Exchange Act.

Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

         William E. McDonald, Associate General Counsel and Deputy Secretary for
the Company, has provided an opinion as to the legality of the securities being
registered hereby. As a result of awards under stock-based compensation plans

Item 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 145 of the Delaware General Corporation Law of the State of
Delaware ("DGCL") grants each corporation organized thereunder, such as the
Company, the power to indemnify its directors and officers against liability for
certain of their acts. Section 102(b)(7) of the DGCL permits a provision in the
certificate of incorporation of each corporation organized thereunder
eliminating or limiting, with certain exceptions, the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director. The Company's certificate of incorporation
contains such a provision. The foregoing statements are subject to the detailed
provisions of Sections 145 and 102(b)(7) of the DGCL.

         Article VI of the Company's Bylaws provides that the Company shall
indemnify its officers, directors and employees to the fullest extent permitted
by the DGCL in connection with proceedings with which any such person is
involved by virtue of his or her status as an officer, director or employee. The
Company has also by contract agreed to indemnify its directors against damages,
judgments, settlements and costs arising out of any actions

                                      II-1
against the directors brought by reason of the fact that they are or were
directors. The Company maintains directors' and officers' liability insurance,
including a reimbursement policy in favor of the Company.

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 of 1933;

                  (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 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 Securities and Exchange Commission
                           pursuant to Rule 424(b) 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(1)(i) and A(1)(ii) above will 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

                                      II-2
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)      That, 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.

         (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 of 1933, 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 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
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 incurred or paid by a director, officer or other
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.

                                      II-3
