ITEM 4.           DESCRIPTION OF SECURITIES.

         Not Applicable.

<PAGE>

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

              Sections 1741 to 1743 of the Pennsylvania Business Corporation Law
("BCL") provide that a corporation may indemnify its representatives (including
directors and officers) against liabilities that they incur in such capacities
provided certain standards are met, including good faith and the reasonable
belief that the particular action is in, or not opposed to, the best interests
of the corporation. In general, this power to indemnify does not exist in the
case of actions against a director or officer by or in the right of the
corporation if the person seeking indemnification is adjudged liable to the
corporation. A corporation is required to indemnify directors and officers
against expenses they may incur in defending actions to which they are made a
party by reason of their status as directors or officers if they are successful
on the merits or otherwise in the defense of such actions.

              Section 1746 of the BCL provides that the foregoing provisions
shall not be deemed exclusive of any other rights to which a person seeking
indemnification may be entitled under, among other things, any provision in the
corporation's articles of incorporation or bylaws, provided 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. Article 11 of the Company's
Amended and Restated Articles of Incorporation and Article IV of the Company's
Bylaws provide for the mandatory indemnification of directors and officers in
accordance with and to the full extent permitted by the laws of Pennsylvania as
in effect at the time of such indemnification.

              Section 1713 of the BCL provides that a corporation may provide in
its bylaws that, subject to certain exceptions, a director shall not be
personally liable for monetary damages for any action taken unless the director
has breached or failed to perform the duties of his office under the BCL and the
breach or failure to perform constitutes self-dealing, willful misconduct or
recklessness. The Company has adopted such a provision in Article IV of its
Bylaws, and the provision eliminates the personal monetary liability of
directors to the full extent permitted by Section 1713 of the BCL.

         The Company has obtained and maintains insurance policies covering its
officers and directors and indemnifying them against loss on account of certain
claims made against them.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED

         Not Applicable.

ITEM 8.           EXHIBITS

         The exhibits listed on the Exhibit Index on page II-9 of this
Registration Statement are filed herewith or are incorporated herein by
reference to other filings.

ITEM 9.           UNDERTAKINGS

The 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 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 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 (i) and (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 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;

<PAGE>

         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, each filing of the Company'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 new securities at that time
                  shall be deemed to be the initial bona fide offering thereof.

         5.       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
                  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 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.

        (b) The Company's Transition Report on Form 10-Q for the transition

        (c) The Company's Quarterly Reports on Form 10-Q for the quarters ended
            January 31, 2000, June 30, 2000 and September 30, 2000;

        (d) The Company's Current Reports on Form 8-K as filed with the
            Commission on May 12, 2000 and August 1, 2000; and

        (e) The description of the Company's Common Stock contained in the
            Company's Registration Statement on Form S-1 filed with the
            Commission on February 28, 1995 and all amendments or reports filed
            for the purpose of updating such description.

         All documents filed by the Registrant after the date of this

Exchange Act, prior to the filing of a post-effective amendment which indicates
that all Common Stock offered hereby has been sold or which deregisters such
Common Stock then remaining unsold, shall be deemed to be incorporated in this
Registration Statement by reference and shall be a part hereof from the date of
filing of such documents. Any statement contained in a document incorporated or
deemed to be incorporated by reference in this Registration Statement shall be
deemed to be modified or superseded for purposes of this Registration Statement
to the extent that a statement contained herein or in any other subsequently
filed document which also is or is deemed to be incorporated by reference in
this Registration Statement modifies or supersedes such statement. Any such
statement so modified or superseded shall not be deemed, except as so modified
or so superseded, to constitute a part of this Registration Statement.

ITEM 4.           DESCRIPTION OF SECURITIES.

         Not Applicable.
ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

              Sections 1741 to 1743 of the Pennsylvania Business Corporation Law
("BCL") provide that a corporation may indemnify its representatives (including
directors and officers) against liabilities that they incur in such capacities
provided certain standards are met, including good faith and the reasonable
belief that the particular action is in, or not opposed to, the best interests
of the corporation. In general, this power to indemnify does not exist in the
case of actions against a director or officer by or in the right of the
corporation if the person seeking indemnification is adjudged liable to the
corporation. A corporation is required to indemnify directors and officers
against expenses they may incur in defending actions to which they are made a
party by reason of their status as directors or officers if they are successful
on the merits or otherwise in the defense of such actions.

              Section 1746 of the BCL provides that the foregoing provisions
shall not be deemed exclusive of any other rights to which a person seeking
indemnification may be entitled under, among other things, any provision in the
corporation's articles of incorporation or bylaws, provided 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. Article 11 of the Company's
Amended and Restated Articles of Incorporation and Article IV of the Company's
Bylaws provide for the mandatory indemnification of directors and officers in
accordance with and to the full extent permitted by the laws of Pennsylvania as
in effect at the time of such indemnification.

              Section 1713 of the BCL provides that a corporation may provide in
its bylaws that, subject to certain exceptions, a director shall not be
personally liable for monetary damages for any action taken unless the director
has breached or failed to perform the duties of his office under the BCL and the
breach or failure to perform constitutes self-dealing, willful misconduct or
recklessness. The Company has adopted such a provision in Article IV of its
Bylaws, and the provision eliminates the personal monetary liability of
directors to the full extent permitted by Section 1713 of the BCL.

         The Company has obtained and maintains insurance policies covering its
officers and directors and indemnifying them against loss on account of certain
claims made against them.

ITEM 7.           EXEMPTION FROM REGISTRATION CLAIMED

         Not Applicable.
ITEM 8.           EXHIBITS

         The exhibits listed on the Exhibit Index on page II-9 of this
Registration Statement are filed herewith or are incorporated herein by
reference to other filings.

ITEM 9.           UNDERTAKINGS

The 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 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 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 (i) and (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 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;
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, each filing of the Company'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 new securities at that time
                  shall be deemed to be the initial bona fide offering thereof.

         5.       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
                  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 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.
