                                    PART II
                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Sections 1741 and 1742 of the Pennsylvania Business Corporation Law (the
"PBCL") provide that a business corporation shall have the power to indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or proceeding whether civil, criminal,
administrative or investigative, by reason of the fact that such person is or
was a director, officer, employee or agent of another domestic or foreign
corporation for profit or not-for-profit, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by such
person in connection with such proceeding, if such person acted in good faith
and in a manner he reasonably believed to be in, or not opposed to, the best
interests of the corporation, and, with respect to any criminal proceeding,
has no reasonable cause to believe his conduct was unlawful. In the case of an
action by or in the right of the corporation, such indemnification is limited
to expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection with the defense or settlement of such action,
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person has been adjudged to be liable to the
corporation unless, and only to the extent that, a court determines upon
application that, despite the adjudication of liability but in view of all the
circumstances, such person is fairly and reasonably entitled to indemnity for
the expenses that the court deems proper.
 
  PBCL Section 1744 provides that, unless ordered by a court, any
indemnification referred to above shall be made by the corporation only as
authorized in the specific case upon a determination that indemnification is
proper in the circumstances because the director, officer, employee or agent
of the corporation has met the applicable standard of conduct. Such
determination shall be made:
 
    (1) by the Board of Directors by a majority vote of a quorum consisting
  of directors who were not parties to the proceeding; or
 
    (2) if such a quorum is not obtainable or if obtainable and a majority
  vote of a quorum of disinterested directors so directs, by independent
  legal counsel in a written opinion; or
 
    (3) by the shareholders.
 
  Notwithstanding the above, PBCL Section 1743 provides that to the extent
that a director, officer, employee or agent of a business corporation is
successful on the merits or otherwise in defense of any proceeding referred to
above as contained in sections 1741 and 1742, or in defense of any claim
therein, such person shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
therewith.
 
  PBCL Section 1745 provides that expenses (including attorneys' fees)
incurred by an officer, director, employee or agent of a business corporation
in defending any such proceeding may be paid by the corporation in advance of
the final disposition of the action or proceeding upon receipt of an
undertaking to repay the amount advanced if it is ultimately determined that
the director, officer, employee or agent of the corporation is not entitled to
be indemnified by the corporation.
 
  PBCL Section 1746 provides that the indemnification and advancement of
expenses provided by, or granted pursuant to, the foregoing provisions is not
exclusive of any other rights to which a person seeking indemnification may be
entitled under any bylaw, agreement, vote of shareholders or disinterested
directors or otherwise both as to action in such person's official capacity
and as to action in another capacity while holding office, and that
indemnification may be granted under any bylaw, agreement, vote of
shareholders or directors or otherwise for any action taken whether or not the
corporation would have the power to indemnify the person under any other
provision of law and whether or not the indemnified liability arises or arose
from any threatened,
 
                                     II-1

 
pending or completed action by or in the right of the corporation, provided,
however, that no indemnification may be made in any case where the act or
failure to act giving rise to the claim for indemnification is determined by a
court to have constituted willful misconduct or recklessness.
 
  The By-Laws of the Registrant provide that the Directors, officers, agents
and employees of the Registrant shall be indemnified as of right to the
fullest extent now or hereafter not prohibited by law in connection with any
actual or threatened action, suit or proceeding, civil, criminal,
administrative, investigative or other (whether brought by or in the right of
the Registrant or otherwise) arising out of their service to the Registrant or
to another enterprise at the request of the Registrant.
 
  PBCL Section 1747 permits a Pennsylvania business corporation to purchase
and maintain insurance on behalf of any person who is or was a director,
officer, employee or agent of the corporation or is or was serving at the
request of the corporation as a director, officer, employee or agent of
another threatened, pending or completed action or other enterprise, against
any liability asserted against such person and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would have the power to indemnify the person against such liability under the
provisions described above.
 
  The By-Laws of the Registrant provide that the Registrant may purchase and
maintain insurance to protect itself and any Director, officer, agent or
employee entitled to indemnification under the By-Laws against any liability
asserted against such person and incurred by such person in respect of the
service of such person to the Registrant whether or not the Registrant would
have the power to indemnify such person against such liability by law or under
the provisions of the By-Laws.
 
  The Registrant maintains directors' and officers' liability insurance
covering its Directors and officers with respect to liabilities, including
liabilities under the Securities Act of 1933, as amended, which they may incur
in connection with their serving as such. Under this insurance, the Registrant
may receive reimbursement for amounts as to which the Directors and officers
are indemnified by the Registrant under the foregoing By-Law indemnification
provision. Such insurance also provides certain additional coverage for the
Directors and officers against certain liabilities even though such
liabilities may not be covered by the foregoing By-Law indemnification
provision.
 
  As permitted by PBCL Section 1713, the By-Laws of the Registrant provide
that no Director shall be personally liable for monetary damages for any
action taken, unless such Director's breach of duty or failure to perform
constituted self-dealing, willful misconduct or recklessness. The PBCL states
that this exculpation from liability does not apply to the responsibility or
liability of a Director pursuant to any criminal statute or the liability of a
Director for the payment of taxes pursuant to Federal, state or local law. It
may also not apply to liabilities imposed upon directors by the Federal
securities laws. PBCL Section 1715(d) creates a presumption, subject to
exceptions, that a Director acted in the best interests of the corporation.
PBCL Section 1712, in defining the standard of care a Director owes to the
corporation, provides that a Director stands in a fiduciary relation to the
corporation and must perform his duties as a Director or as a member of any
committee of the Board in good faith, in a manner he reasonably believes to be
in the best interest of the corporation and with such care, including
reasonable inquiry, skill and diligence, as a person of ordinary prudence
would use under similar circumstances.

ITEM 22. UNDERTAKINGS.
 
  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;
 
  (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.
 
  (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.
 
  (4) 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 Securities Exchange Act of 1934 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 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.
 
  (5) That prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this registration
statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus
will contain the information called for by the applicable registration form
with respect to reofferings by persons who may be deemed underwriters, in
addition to the information called for by the other Items of the applicable
form.
 
  (6) That every prospectus (i) that is filed pursuant to paragraph (5)
immediately preceding, or (ii) that purports to meet the requirements of
section 10(a)(3) of the Act and is used in connection with an offering of
securities subject to Rule 415, will be filed as a part of an amendment to the
registration statement and will not be used until such amendment is effective,
and 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.
 
  (7) To respond to requests for information that is incorporated by reference
into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within
one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means. This includes
information contained in documents filed subsequent to the effective date of
the registration statement through the date of responding to the request.
 
  (8) To supply by means of a post-effective amendment all required information
concerning a transaction, and the company being acquired involved therein, and
that was not the subject of and included in the registration statement when it
became effective.
 
 
                                      II-4

 
  Insofar as indemnification for liabilities raising 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 ha 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.

has duly caused this amendment to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Pittsburgh, Commonwealth of
Pennsylvania, on March 26, 1998.
