      INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE

     The following documents filed by the Registrant with the
Securities and Exchange Commission are incorporated herein by
reference.

     (a)  Annual Report on Form 10-K for the fiscal year ended

     (c)  The description of the Registrant's Common Stock set
forth in the Registrant's Registration Statement filed pursuant
to Section 12 of the Securities Exchange Act of 1934, as
amended (the "Exchange Act") and any amendments or reports
filed for the purpose of updating such description.

ITEM 4.  DESCRIPTION OF SECURITIES

     Not Applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

     The legality of the securities to which this Registration
Statement relates has been passed upon by Thomas F. Seligson,
Counsel of the Company.  Mr. Seligson is eligible to
participate in the Plan.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article V of the By-laws of the Company provides that the
Company shall indemnify, under specified circumstances, persons
who were or are directors, officers or employees of the Company
or who served or serve other business entities at the request
of the Company.  Under these By-law provisions, a person who is
wholly successful in defending a claim will be indemnified for
any reasonable expenses.  To the extent a person is not
successful in defending a claim, reasonable expenses of the
defense and any liability incurred are to be indemnified under
these provisions only where independent legal counsel or other
disinterested person selected by the Board of Directors
determines that such person acted in good faith and in a manner
such person reasonably believed to be in, or not opposed to,
the best interests of the Company, and in addition with respect
to any criminal action or proceeding, had no reasonable cause
to believe the conduct of such person was unlawful.  Any
expense incurred with respect to any claim may be advanced by
the Company if the recipient agrees to repay such amount if it
is ultimately determined that such recipient is not to be
indemnified pursuant to Article V.

     The foregoing By-law provisions generally parallel
Sections 1741 and 1745 of the Pennsylvania Business Corporation
Law ("BCL").  Section 1746 and the By-laws both also provide
that the indemnification provided for therein shall not be
deemed exclusive of any other rights to which those seeking
indemnification may otherwise be entitled.

     Section 1746 of the BCL and the By-laws provide for
increased
indemnification protections for directors, officers and others.
Indemnification may be provided by Pennsylvania corporations in
any case except 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.

     Section 1713 of the BCL also sets forth a framework
whereby Pennsylvania corporations, with the approval of the
shareholders, may limit the personal liability of directors for
monetary damages except where the act or omission giving rise
to a claim constitutes self-dealing, willful misconduct or
recklessness.  The section does not apply to a director's
responsibility or liability under a criminal or tax statute and
may not apply to liability under Federal statutes, such as the
Federal securities laws.

     The Company's Articles and By-laws were amended by the
shareholders to implement the increased protections made
available to directors under the BCL as described in the
preceding paragraph. Article VIII of the By-laws provides that,
except as prohibited by law, every director of the Company
shall be entitled as of right to be indemnified by the Company
for expenses and any and all liability paid or incurred by such
person by reason of such person being or having been a director
of the Company.  Expenses incurred with respect to any claim
may be advanced by the Company, subject to certain exceptions.
The shareholders have also approved a form of indemnity
agreement.  The Company has entered into such an indemnity
agreement with each of its current directors.

    The Company has purchased a one year liability insurance
policy with an aggregate limit of $75 million, with certain
specified deductible amounts, for liability of directors and
officers and reimbursement to the Company for indemnification
provided to directors and officers.  The policy has an
expiration date of October 1, 1997 and provides liability
insurance and reimbursement coverage for the Company, and its
directors and officers, which is permitted by the laws of
Pennsylvania referred to above.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED

ITEM 8.  EXHIBITS

Exhibit
Number                          Description


(5)      Opinion of Thomas F. Seligson, Counsel of the Company.

(15)     Letter from Independent Public Accountants regarding
         unaudited financial information.

(23)(a)  Consent of Coopers & Lybrand L.L.P.

(23)(b)  Consent of Counsel (included as part of Exhibit 5).

(24)     Powers of Attorney of certain officers and directors
         of the Company.

ITEM 9.  UNDERTAKINGS

     The Company 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 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) of this section do not apply if the information
required to be included in a post-effective amendment by those
paragraphs 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 this 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; and

     (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
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.

     Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the Company pursuant to the
foregoing provisions described in Item 6 above, the Company has
been informed 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 Company
of expenses incurred or paid by a director, officer or
controlling person of the Company 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 Company 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.

     The legality of the securities to which this Registration
Statement relates has been passed upon by Thomas F. Seligson,
Counsel of the Company.  Mr. Seligson is eligible to

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article V of the By-laws of the Company provides that the
Company shall indemnify, under specified circumstances, persons
who were or are directors, officers or employees of the Company
or who served or serve other business entities at the request
of the Company.  Under these By-law provisions, a person who is
wholly successful in defending a claim will be indemnified for
any reasonable expenses.  To the extent a person is not
successful in defending a claim, reasonable expenses of the
defense and any liability incurred are to be indemnified under
these provisions only where independent legal counsel or other
disinterested person selected by the Board of Directors
determines that such person acted in good faith and in a manner
such person reasonably believed to be in, or not opposed to,
the best interests of the Company, and in addition with respect
to any criminal action or proceeding, had no reasonable cause
to believe the conduct of such person was unlawful.  Any
expense incurred with respect to any claim may be advanced by
the Company if the recipient agrees to repay such amount if it
is ultimately determined that such recipient is not to be
indemnified pursuant to Article V.

     The foregoing By-law provisions generally parallel
Sections 1741 and 1745 of the Pennsylvania Business Corporation
Law ("BCL").  Section 1746 and the By-laws both also provide
that the indemnification provided for therein shall not be
deemed exclusive of any other rights to which those seeking
indemnification may otherwise be entitled.

     Section 1746 of the BCL and the By-laws provide for
increased
indemnification protections for directors, officers and others.
Indemnification may be provided by Pennsylvania corporations in
any case except 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.

     Section 1713 of the BCL also sets forth a framework
whereby Pennsylvania corporations, with the approval of the
shareholders, may limit the personal liability of directors for
monetary damages except where the act or omission giving rise
to a claim constitutes self-dealing, willful misconduct or
recklessness.  The section does not apply to a director's
responsibility or liability under a criminal or tax statute and
may not apply to liability under Federal statutes, such as the
Federal securities laws.

     The Company's Articles and By-laws were amended by the
shareholders to implement the increased protections made
available to directors under the BCL as described in the
preceding paragraph. Article VIII of the By-laws provides that,
except as prohibited by law, every director of the Company
shall be entitled as of right to be indemnified by the Company
for expenses and any and all liability paid or incurred by such
person by reason of such person being or having been a director
of the Company.  Expenses incurred with respect to any claim
may be advanced by the Company, subject to certain exceptions.
The shareholders have also approved a form of indemnity
agreement.  The Company has entered into such an indemnity
agreement with each of its current directors.

    The Company has purchased a one year liability insurance
policy with an aggregate limit of $75 million, with certain
specified deductible amounts, for liability of directors and
officers and reimbursement to the Company for indemnification
provided to directors and officers.  The policy has an
expiration date of October 1, 1997 and provides liability
insurance and reimbursement coverage for the Company, and its
directors and officers, which is permitted by the laws of
Pennsylvania referred to above.

ITEM 9.  UNDERTAKINGS

     The Company 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 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) of this section do not apply if the information
required to be included in a post-effective amendment by those
paragraphs 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 this 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; and

     (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
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.

     Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors,
officers and controlling persons of the Company pursuant to the
foregoing provisions described in Item 6 above, the Company has
been informed 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 Company
of expenses incurred or paid by a director, officer or
controlling person of the Company 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 Company 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.
