reference into this Registration Statement the following documents previously
filed with the Securities and Exchange Commission (the "Commission"):

                           (a)      The Company's Annual Report on Form 10-K for
                                    the fiscal year ended July 31, 2001, filed

                                    Commission on September 5, 1996, pursuant to
                                    Section 12 of the Securities Act of 1934, as
                                    amended (the "1934 Act") and the Company's
                                    Registration Statement on Form 8-A12B, filed
                                    with the Commission on May 31, 2000,
                                    pursuant to Section 12 of the 1934 Act.

                  All documents filed by the Company or by the Plan pursuant to
Section 13(a), 13(c), 14 or 15(d) of the 1934 Act, after the date of this
Registration Statement 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 then remaining unsold, shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents. Any statement contained in a

deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any subsequently filed

not be deemed, except as so modified or superseded, to constitute a part of this
Registration Statement.

ITEM 4.           DESCRIPTION OF SECURITIES.

                  Not Applicable.

                  Not Applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

                  Section 1741 of the Associations Code of the Commonwealth of
Pennsylvania (the "Associations Code") provides that the Company may indemnify a
director or officer

<PAGE>   3
                                     - 3 -


against his or her expenses and, other than in an action by or in the right of
the Company, judgments, fines and amounts paid in settlement in connection with
any action or proceeding involving such person by reason of the fact that such
person is or was a director or officer, concerning actions taken in good faith
and in a manner reasonably believed to be in, or not opposed to, the best
interests of the Company, and, with respect to any criminal action or
proceeding, such person had no reason to believe his or her conduct was
unlawful. Section 1742 of the Associations Code provides that in a derivative
action, no indemnification shall be made with respect to any claim, issue or
matter as to which such director or officer shall have been adjudged to be
liable to the Company unless and only to the extent that the appropriate court
of the Commonwealth of Pennsylvania shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such director or officer is fairly and reasonably entitled to
indemnity for such expenses which the court shall deem proper. Additionally, the
Company is required, pursuant to Associations Code Section 1743, to indemnify
its directors and officers against expenses to the extent that such directors or
officers have been successful on the merits or otherwise in any third party or
derivative action or proceedings or in the defense of any claim, issue or matter
therein. Furthermore, Section 1747 of the Associations Code declares that a
corporation's purchase of indemnification insurance for officers or directors is
consistent with the public policy of the Commonwealth of Pennsylvania.

                  The Company's By-Laws and Articles of Incorporation relating
to the limitation of the personal liability of the Company's directors and
officers for monetary damages and to the indemnification of the Company's
directors and officers (1) limit the personal liability of a director or officer
for monetary damages for any act or omission unless the director or officer has
breached or failed to perform the duties of his office as required under
Pennsylvania law and the breach or failure to perform constitutes self-dealing,
willful misconduct or recklessness, and (2) require the Company to indemnify
directors, officers and employees for liability or expenses incurred in such
capacity, except if the person's conduct was determined to constitute
self-dealing, willful misconduct or recklessness.

                  Pursuant to policies of directors' and officers' liability and
corporation reimbursement insurance, the Company's officers and directors are
insured, subject to the limits, deductibles, exceptions and other items and
conditions of such policies, against liability for an actual or alleged breach
of duty, neglect, error, misstatement, misleading statement, omission, or other
act done or wrongfully attempted while acting in their capacities as directors
or officers of the Company.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED.

                  Not Applicable.

                  The Company has obtained from the Internal Revenue Service a
determination letter that the Plan is qualified under Section 401 of the
Internal Revenue Code of 1986, as amended, and hereby undertakes to submit any
amendments to the Plan to the IRS in a timely manner and to make any changes
required by the IRS to maintain the qualification of the Plan under Section 401.


ITEM 9.           UNDERTAKINGS.

                  A. The undersigned registrants hereby undertake: (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. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not

<PAGE>   5
                                     - 5 -


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 Commission pursuant to Rule 424(b)(Section 230.424(b) of this
chapter) 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,
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 (1)(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 a 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 at the termination of the offering.

                  B. The undersigned registrants hereby undertake that, for
purposes of determining any liability under the 1933 Act, each filing of the
registrants' annual reports pursuant to Section 13(a) or Section 15(d) of the
1934 Act (where applicable, each filing of an employee benefit plan's annual
report pursuant to section 15(d) of the 1934 Act) that is incorporated by
reference into 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 1933 Act may be permitted to directors, officers, or controlling persons of
the registrants pursuant to the foregoing provisions, or otherwise, the
registrants have 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 a registrant of expenses incurred or
paid by a director, officer, or controlling person of a registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer of registrant, or controlling person in connection with the
securities being registered, a 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 Company's Annual Report on Form 10-K for
                                    the fiscal year ended July 31, 2001, filed

                                    Commission on September 5, 1996, pursuant to
                                    Section 12 of the Securities Act of 1934, as
                                    amended (the "1934 Act") and the Company's
                                    Registration Statement on Form 8-A12B, filed
                                    with the Commission on May 31, 2000,
                                    pursuant to Section 12 of the 1934 Act.

                  All documents filed by the Company or by the Plan pursuant to
Section 13(a), 13(c), 14 or 15(d) of the 1934 Act, after the date of this

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 1741 of the Associations Code of the Commonwealth of
Pennsylvania (the "Associations Code") provides that the Company may indemnify a
director or officer
3
                                     - 3 -

against his or her expenses and, other than in an action by or in the right of
the Company, judgments, fines and amounts paid in settlement in connection with
any action or proceeding involving such person by reason of the fact that such
person is or was a director or officer, concerning actions taken in good faith
and in a manner reasonably believed to be in, or not opposed to, the best
interests of the Company, and, with respect to any criminal action or
proceeding, such person had no reason to believe his or her conduct was
unlawful. Section 1742 of the Associations Code provides that in a derivative
action, no indemnification shall be made with respect to any claim, issue or
matter as to which such director or officer shall have been adjudged to be
liable to the Company unless and only to the extent that the appropriate court
of the Commonwealth of Pennsylvania shall determine upon application that,
despite the adjudication of liability but in view of all the circumstances of
the case, such director or officer is fairly and reasonably entitled to
indemnity for such expenses which the court shall deem proper. Additionally, the
Company is required, pursuant to Associations Code Section 1743, to indemnify
its directors and officers against expenses to the extent that such directors or
officers have been successful on the merits or otherwise in any third party or
derivative action or proceedings or in the defense of any claim, issue or matter
therein. Furthermore, Section 1747 of the Associations Code declares that a
corporation's purchase of indemnification insurance for officers or directors is
consistent with the public policy of the Commonwealth of Pennsylvania.

                  The Company's By-Laws and Articles of Incorporation relating
to the limitation of the personal liability of the Company's directors and
officers for monetary damages and to the indemnification of the Company's
directors and officers (1) limit the personal liability of a director or officer
for monetary damages for any act or omission unless the director or officer has
breached or failed to perform the duties of his office as required under
Pennsylvania law and the breach or failure to perform constitutes self-dealing,
willful misconduct or recklessness, and (2) require the Company to indemnify
directors, officers and employees for liability or expenses incurred in such
capacity, except if the person's conduct was determined to constitute
self-dealing, willful misconduct or recklessness.

                  Pursuant to policies of directors' and officers' liability and
corporation reimbursement insurance, the Company's officers and directors are
insured, subject to the limits, deductibles, exceptions and other items and
conditions of such policies, against liability for an actual or alleged breach
of duty, neglect, error, misstatement, misleading statement, omission, or other
act done or wrongfully attempted while acting in their capacities as directors
or officers of the Company.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED.

                  Not Applicable.

                  The Company has obtained from the Internal Revenue Service a
determination letter that the Plan is qualified under Section 401 of the
Internal Revenue Code of 1986, as amended, and hereby undertakes to submit any
amendments to the Plan to the IRS in a timely manner and to make any changes
required by the IRS to maintain the qualification of the Plan under Section 401.

ITEM 9.           UNDERTAKINGS.

                  A. The undersigned registrants hereby undertake: (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. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not
5
                                     - 5 -

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 Commission pursuant to Rule 424(b)(Section 230.424(b) of this
chapter) 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,
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 (1)(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 a 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 at the termination of the offering.

                  B. The undersigned registrants hereby undertake that, for
purposes of determining any liability under the 1933 Act, each filing of the
registrants' annual reports pursuant to Section 13(a) or Section 15(d) of the
1934 Act (where applicable, each filing of an employee benefit plan's annual
report pursuant to section 15(d) of the 1934 Act) that is incorporated by
reference into 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 1933 Act may be permitted to directors, officers, or controlling persons of
the registrants pursuant to the foregoing provisions, or otherwise, the
registrants have 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 a registrant of expenses incurred or
paid by a director, officer, or controlling person of a registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
director, officer of registrant, or controlling person in connection with the
securities being registered, a 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.
