Item 5.  Interests of Named Experts and Counsel

         Not Applicable.

Item 6.  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

                                       -2-
<PAGE>

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, 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 Articles of Incorporation and By-Laws of the registrant provide
that, except as prohibited by law and as described below, the directors and
officers of the registrant shall be indemnified as of right in connection with
any actual or threatened claim, 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, except no right to
indemnification shall exist in any case where the act or failure to act giving
rise to the claim to indemnification is determined by a court to have
constituted willful misconduct or recklessness and no such indemnification shall
exist with respect to an action brought by such officer or director against 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 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 Articles of Incorporation and By-Laws of the registrant also
provide that the registrant may purchase and maintain insurance to protect
itself and any director or officer entitled to indemnification under the By-Laws
against any liability or expense asserted against such person and incurred by
such person in respect of the service of

                                       -3-
<PAGE>

such person to the registrant whether or not the registrant would have the power
to indemnify such person against such liability or expenses 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 provisions.

         As permitted by PBCL Section 1713, the Articles of Incorporation and
By-Laws of the registrant provide that no director shall be personally liable
for monetary damages for any action taken or any failure to take any action
unless such liability results from the director's breach of duty of performance
of duty or any failure of performance which occurred prior to January 27, 1987.
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 interests of the corporation and with such care, including
reasonable inquiry, skill and diligence, as a person or ordinary prudence would
use under similar circumstances.

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 offered
                           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) do 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 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.

                                       -5-
<PAGE>

         (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
Securities Exchange Act of 1934, as amended, 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.

         (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 registrant's Certificate of
Incorporation or by-laws, by contract, 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

         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

                                       -2-
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, 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 Articles of Incorporation and By-Laws of the registrant provide
that, except as prohibited by law and as described below, the directors and
officers of the registrant shall be indemnified as of right in connection with
any actual or threatened claim, 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, except no right to
indemnification shall exist in any case where the act or failure to act giving
rise to the claim to indemnification is determined by a court to have
constituted willful misconduct or recklessness and no such indemnification shall
exist with respect to an action brought by such officer or director against 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 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 Articles of Incorporation and By-Laws of the registrant also
provide that the registrant may purchase and maintain insurance to protect
itself and any director or officer entitled to indemnification under the By-Laws
against any liability or expense asserted against such person and incurred by
such person in respect of the service of

                                       -3-
such person to the registrant whether or not the registrant would have the power
to indemnify such person against such liability or expenses 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 provisions.

         As permitted by PBCL Section 1713, the Articles of Incorporation and
By-Laws of the registrant provide that no director shall be personally liable
for monetary damages for any action taken or any failure to take any action
unless such liability results from the director's breach of duty of performance
of duty or any failure of performance which occurred prior to January 27, 1987.
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 interests of the corporation and with such care, including
reasonable inquiry, skill and diligence, as a person or ordinary prudence would
use under similar circumstances.

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 offered
                           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) do 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 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.

                                       -5-
(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
Securities Exchange Act of 1934, as amended, 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.

         (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 registrant's Certificate of
Incorporation or by-laws, by contract, 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.

                                       -6-
SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, as amended,
the registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-8 and has duly caused this
registration statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Pittsburgh, Commonwealth of Pennsylvania, on May
