ITEM 5.  INTEREST OF NAMED EXPERTS AND COUNSEL.

         The legality of the Common Shares offered hereby has been passed upon
for the Company by Amy B. Haynes, Assistant General Counsel; Practice Group
Head-Securities and Corporate Governance of the Company. Ms. Haynes holds Common
Shares of the Company, as well as vested and unvested options to purchase Common
Shares of the Company, and unvested restricted Common Shares of the Company.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 1701.13(E) of the Ohio Revised Code sets forth conditions and
limitations governing the indemnification of officers, directors, and other
persons.

         Article 6 of the Company's Restated Code of Regulations ("Code of
Regulations"), as amended and restated, contains certain indemnification
provisions adopted pursuant to authority contained in Section 1701.13(E) of the
Ohio Revised Code. The Company's Code of Regulations provides for the
indemnification of its officers, directors, employees, and agents




                                      -2-
   3

against all expenses with respect to any judgments, fines, and amounts paid in
settlement, or with respect to any threatened, pending, or completed action,
suit, or proceeding to which they were or are parties or are threatened to be
made parties by reason of acting in such capacities, provided that it is
determined, either by a majority vote of a quorum of disinterested directors of
the Company or the shareholders of the Company or otherwise as provided in
Section 1701.13(E) of the Ohio Revised Code, that (a) they acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interest of the Company; (b) in any action, suit, or proceeding by or in the
right of the Company, they were not, and have not been adjudicated to have been,
negligent or guilty of misconduct in the performance of their duties to the
Company; and (c) with respect to any criminal action or proceeding, that they
had no reasonable cause to believe that their conduct was unlawful. Section
1701.13(E) provides that to the extent a director, officer, employee, or agent
has been successful on the merits or otherwise in defense of any such action,
suit, or proceeding, such individual shall be indemnified against expenses
reasonably incurred in connection therewith. At present there are no material
claims, actions, suits, or proceedings pending where indemnification would be
required under these provisions, and the Company does not know of any such
threatened claims, actions, suits, or proceedings which may result in a request
for such indemnification.

         The Company has entered into indemnification contracts with each of its
directors and executive officers. These contracts generally: (i) confirm the
existing indemnity provided to them under the Company's Code of Regulations and
assure that this indemnity will continue to be provided; (ii) provide that if
the Company does not maintain directors' and officers' liability insurance, the
Company will, in effect, become a self-insurer of the coverage; and (iii)
provide that, in addition, the directors and officers shall be indemnified to
the fullest extent permitted by law against all expenses (including legal fees),
judgments, fines, and settlement amounts incurred by them in any action or
proceeding on account of their service as a director, officer, employee, or
agent of the Company, or at the request of the Company as a director, officer,
employee, trustee, fiduciary, manager, member or agent of another corporation,
partnership, trust, limited liability company, employee benefit plan or other
enterprise and; (iv) provide for the mandatory advancement of expenses to the
executive officer or director in connection with the defense of any proceedings,
provided that the executive officer or director agrees to reimburse the Company
for that advancement if it is ultimately determined that the executive officer
or director is not entitled to the indemnification for that proceeding under the
agreement. Coverage under the contracts is excluded: (A) on account of conduct
which is finally adjudged to be knowingly fraudulent, deliberately dishonest, or
willful misconduct; or (B) if a final court of adjudication shall determine that
such indemnification is not lawful; or (C) in respect of any suit in which
judgment is rendered for violations of Section 16(b) of the Securities and
Exchange Act of 1934, as amended, or provisions of any federal, state, or local
statutory law; or (D) on account of any remuneration paid which is finally
adjudged to have been in violation of law; or (E) on account of conduct
occurring prior to the time the executive officer or director became an officer,
director, employee or agent of the Company or its subsidiaries (but in no event
earlier than the time such entity became a subsidiary of the Company); or (F)
with respect to proceedings initiated or brought voluntarily by the executive
officer or director and not by way of defense, except for proceedings brought to
enforce rights under the indemnification contract.

         The Company maintains a directors' and officers' insurance policy which
insures the officers and directors of the Company from any claim arising out of
an alleged wrongful act by such persons in their respective capacities as
officers and directors of the Company.

(1)      Included as an exhibit to the Company's Registration Statement on Form
         S-4 (No. 333-74761) and incorporated herein by reference.

(2)      Included as an exhibit to the Company's Current Report on Form 8-K
         filed on November 24, 1998 and incorporated herein by reference.

(3)      Included as an exhibit to the Company's Registration Statement on Form
         S-4 (No. 333-53394) and incorporated herein by reference.

         The Company hereby undertakes that the Allegiance Retirement Plan for
Union Employees of Hayward, California and any amendment thereto ("Plan") has
been or will be submitted to the Internal Revenue Service ("IRS") in a timely
manner and all changes required by the IRS in order to qualify the Plan will be
made.

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, as
amended (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



                                      -4-
   5

a fundamental change in the information set forth in the registration statement;
and (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 clauses (i) and (ii) do not apply if the information required to
be included in a post-effective amendment by those clauses is contained in
periodic reports filed with or furnished to the Commission by the Registrant
pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the registration statement;

         (2) 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 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 at the termination of
the offering.

B. 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 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
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 6 above or otherwise,
the Registrant has been advised that in the opinion of the 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.
