ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Subchapter D of Chapter 17 of the Pennsylvania Business Corporations
Law (the "PBCL") provides in general that a corporation may indemnify any
person, including its directors, officers and employees, 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
(including actions by or in the right of the corporation) by reason of the fact
that he or she is or was a representative of or serving at the request of the
corporation, against expenses (including legal fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with the action or proceeding if he or she is determined by the board
of directors, or in certain circumstances by independent legal counsel to the
shareholders, to have acted in good faith and in a manner he or she reasonably
believed to be in, or not opposed to, the best interests of the corporation and,
with respect to any criminal proceeding, had no reason to believe his or her
conduct was unlawful. In the case of actions by or in the right of the
corporation, indemnification is not permitted in respect of any claim, issue or
matter as to which the person has been adjudged to be liable to the corporation
except to the extent a court determines that the person is fairly and reasonably
entitled to indemnification. In any case, to the extent that the person has been
successful on the merits or otherwise in defense of any claim, issue or matter,
he or she shall be indemnified against expenses (including legal fees) actually
and reasonably incurred by him or her in connection therewith. Subchapter D of
Chapter 17 also provides that the indemnification permitted or required thereby
is not exclusive of any other rights to which a person seeking indemnification
may be entitled.

         The Company's Bylaws provide that the Company shall indemnify any
person who was or is made a party to, or threatened to be made a party to, or is
involved in, any action, suit, or proceeding (including actions by or in the
right of the Company) by reason of the fact that he or she is or was a director
or officer of the Company (or is or was serving at the request of the Company as
a director, officer, trustee, employee, or agent of a related enterprise
including service with respect to an employee benefit plan or is or was serving
at the specific written request of the Company as a director, officer, trustee,
employee, or agent of an unrelated enterprise) against all expenses and
liability he or she actually incurs, including, without limitation, judgments
and amounts paid or to be paid in settlement of or in actions brought by or in
the right of the Company, to the fullest extent permitted by law. Also,
directors and officers are entitled to payment in advance of expenses incurred
in defending any such action, suit or proceeding, upon receipt of an undertaking
to repay all amounts so advanced if it is ultimately determined that they are
not entitled to be indemnified or, in the case of criminal action, a majority of
the Board of Directors so determines. In addition, the Company has entered into
indemnification agreements with each of its directors which entitle the director
to indemnification for certain expenses to the fullest extent permitted by law.

         Article SIXTH, Section (D) of the Company's Amended and Restated
Articles of Incorporation also provides, pursuant to Section 1713 of the PBCL,
that a director of the Company shall not be personally liable for monetary
damages as such for any action taken, or any failure to take any action, unless:
(1) the director has breached or failed to perform the duties of his/her office
under Section 1712 of the PBCL (relating to standard of conduct and justifiable
reliance) and (2) the breach or failure to perform constitutes self-dealing,
willful misconduct or recklessness. This limitation on the personal liability of
directors of the Company does not apply to: (1) the responsibility or liability
of a director pursuant to any criminal statute or (2) the liability of a
director for the payment of taxes pursuant to local, state or federal law.

ITEM 9.  UNDERTAKINGS.

         The Company hereby undertakes:

(a)      To file, during any period in which offers or sales are being made, a
         post-effective amendment to this Registration Statement:

         (1)      to include any prospectus required by Section 10(a)(3) of the
                  Securities Act;

         (2)      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; and

         (3)      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 paragraphs (a)(1) and (a)(2) 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
         Company pursuant to Section 13 or Section 15(d) of the Exchange Act
         that are incorporated by reference in this Registration Statement.

(b)      That, for the purposes 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.

(c)      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.

(d)      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 Exchange Act 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.

(e)      Insofar as indemnification for liabilities arising under the Securities
         Act may be permitted to directors, officers and controlling persons of
         the Company pursuant to the foregoing provisions, or otherwise, the
         Company 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 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
         Securities Act and will be governed by the final adjudication of such
         issue.




                                   SIGNATURES

Pursuant to the requirements of the Securities Act, the Company 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
Lancaster, Commonwealth of Pennsylvania, on the 10th day of October, 2006.

ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Subchapter D of Chapter 17 of the Pennsylvania Business Corporations
Law (the "PBCL") provides in general that a corporation may indemnify any
person, including its directors, officers and employees, 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
(including actions by or in the right of the corporation) by reason of the fact
that he or she is or was a representative of or serving at the request of the
corporation, against expenses (including legal fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him or her in
connection with the action or proceeding if he or she is determined by the board
of directors, or in certain circumstances by independent legal counsel to the
shareholders, to have acted in good faith and in a manner he or she reasonably
believed to be in, or not opposed to, the best interests of the corporation and,
with respect to any criminal proceeding, had no reason to believe his or her
conduct was unlawful. In the case of actions by or in the right of the
corporation, indemnification is not permitted in respect of any claim, issue or
matter as to which the person has been adjudged to be liable to the corporation
except to the extent a court determines that the person is fairly and reasonably
entitled to indemnification. In any case, to the extent that the person has been
successful on the merits or otherwise in defense of any claim, issue or matter,
he or she shall be indemnified against expenses (including legal fees) actually
and reasonably incurred by him or her in connection therewith. Subchapter D of
Chapter 17 also provides that the indemnification permitted or required thereby
is not exclusive of any other rights to which a person seeking indemnification
may be entitled.

         The Company's Bylaws provide that the Company shall indemnify any
person who was or is made a party to, or threatened to be made a party to, or is
involved in, any action, suit, or proceeding (including actions by or in the
right of the Company) by reason of the fact that he or she is or was a director
or officer of the Company (or is or was serving at the request of the Company as
a director, officer, trustee, employee, or agent of a related enterprise
including service with respect to an employee benefit plan or is or was serving
at the specific written request of the Company as a director, officer, trustee,
employee, or agent of an unrelated enterprise) against all expenses and
liability he or she actually incurs, including, without limitation, judgments
and amounts paid or to be paid in settlement of or in actions brought by or in
the right of the Company, to the fullest extent permitted by law. Also,
directors and officers are entitled to payment in advance of expenses incurred
in defending any such action, suit or proceeding, upon receipt of an undertaking
to repay all amounts so advanced if it is ultimately determined that they are
not entitled to be indemnified or, in the case of criminal action, a majority of
the Board of Directors so determines. In addition, the Company has entered into
indemnification agreements with each of its directors which entitle the director
to indemnification for certain expenses to the fullest extent permitted by law.

                                       3
Article SIXTH, Section (D) of the Company's Amended and Restated
Articles of Incorporation also provides, pursuant to Section 1713 of the PBCL,
that a director of the Company shall not be personally liable for monetary
damages as such for any action taken, or any failure to take any action, unless:
(1) the director has breached or failed to perform the duties of his/her office
under Section 1712 of the PBCL (relating to standard of conduct and justifiable
reliance) and (2) the breach or failure to perform constitutes self-dealing,
willful misconduct or recklessness. This limitation on the personal liability of
directors of the Company does not apply to: (1) the responsibility or liability
of a director pursuant to any criminal statute or (2) the liability of a
director for the payment of taxes pursuant to local, state or federal law.

ITEM 9.  UNDERTAKINGS.

         The Company hereby undertakes:

(a)      To file, during any period in which offers or sales are being made, a
         post-effective amendment to this Registration Statement:

         (1)      to include any prospectus required by Section 10(a)(3) of the
                  Securities Act;

         (2)      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; and

         (3)      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 paragraphs (a)(1) and (a)(2) 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
         Company pursuant to Section 13 or Section 15(d) of the Exchange Act
         that are incorporated by reference in this Registration Statement.

(b)      That, for the purposes 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.

(c)      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.

(d)      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 Exchange Act 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.

                                       5
(e)      Insofar as indemnification for liabilities arising under the Securities
         Act may be permitted to directors, officers and controlling persons of
         the Company pursuant to the foregoing provisions, or otherwise, the
         Company 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 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
