     Inc. (the "Registrant" or the "Company") and The First National Bank of

     Stock. This Registration Statement also relates to any additional shares of
     Common Stock which become issuable under the Executive Employment Agreement
     with respect to the options by reason of any stock dividend, stock split,
     recapitalization or other similar transaction effected without the
     Registrant's receipt of consideration that results in an increase in the
     number of the outstanding shares of the Registrant's Common Stock.

     by Section 6(b) of the Securities Act of 1933, as amended (the "Securities

ITEM 4. DESCRIPTION OF SECURITIES.

          Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     The opinion as to the legality of the securities registered hereunder is
     being given by Kevin Bloomfield, Vice President, Secretary and General
     Counsel of the Registrant. Mr. Bloomfield owns shares of the Company's
     common stock, holds options to purchase shares of such common stock,
     restricted stock units and performance shares and participates in the
     Company's employee benefit plans.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 145(a) of the General Corporation Law of the State of Delaware
     ("Delaware Corporation Law") provides, in general, that a 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, suit or proceeding, whether civil, criminal, administrative or
     investigative (other than an action by or in the right of the corporation),
     because the person is or was a director or officer of the corporation. Such
     indemnity may be against expenses (including attorneys' fees), judgments,
     fines and amounts paid in settlement actually and reasonably incurred by
     the person in connection with such action, suit or proceeding, if the
     person acted in good faith and in a manner the person reasonably believed
     to be in or not opposed to the best interests of the corporation and if,
     with respect to any criminal action or proceeding, the person did not have
     reasonable cause to believe the person's conduct was unlawful.

          Section 145(b) of the Delaware Corporation Law provides, in general,
     that a 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 suit by or in the right of the corporation to
     procure a judgment in its favor because the person is or was a director or
     officer of the corporation, against any expenses (including attorneys'
     fees) actually and reasonably incurred by the person in connection with the
     defense or settlement of such action or suit if the person acted in good
     faith and in a manner the person reasonably believed to be in or not
     opposed to the best interests of the corporation, except that no
     indemnification shall be made in respect of any claim, issue or matter as
     to which such person shall have been adjudged to be liable to the
     corporation unless and only to the extent that the Court of Chancery or the
     court in which such action or suit was brought shall determine upon
     application that, despite the adjudication of liability but in view of all
     the circumstances of the case, such person is fairly and reasonably
     entitled to indemnity for such expenses which the Court of Chancery or such
     other court shall deem proper.

<PAGE>

          Section 145(g) of the Delaware Corporation Law provides, in general,
     that a corporation shall have the power to purchase and maintain insurance
     on behalf of any person who is or was a director or officer of the
     corporation against any liability asserted against the person in any such
     capacity, or arising out of the person's status as such, whether or not the
     corporation would have the power to indemnify the person against such
     liability under the provisions of the Delaware Corporation Law. The Company
     has obtained a directors' and officers' liability insurance policy, which
     insures the Company's directors and officers against certain liabilities,
     including liabilities for which the Company may not be able to indemnify
     such persons. The Company has also entered into indemnification agreements
     with certain of its directors and executive officers, which provide for
     indemnification against expenses, judgments, fines and settlements in
     connection with threatened or pending litigation, inquiries or
     investigations that arise out of the director's or officer's acts or
     omissions in his capacity as a director or officer of the Company to the
     extent permitted by Delaware law.

          Article Eight of the Registrant's Restated Certificate of
     Incorporation and Article V of the Registrant's Amended and Restated Bylaws
     provide for indemnification and/or exculpation to the fullest extent
     authorized by the Delaware Corporation Law for any person who is or was a
     director or officer of the Registrant who is or was involved or threatened
     to be made so involved in any proceeding, whether civil, criminal,
     administrative or investigative, by reason of the fact that such person is
     or was serving as a director or officer of the Registrant or was serving at
     the request of the Registrant as a director or officer of any other
     enterprise.

          The foregoing is only a general summary of certain aspects of Delaware
     law and the Registrant's organizational documents dealing with
     indemnification of directors and officers, and does not purport to be
     complete. It is qualified in its entirety by reference to the detailed
     provisions of Section 145 of the Delaware Corporation Law, Article Eight of
     the Registrant's Restated Certificate of Incorporation and Article V of the
     Registrant's Amended and Restated Bylaws.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

          Not applicable.

ITEM 8. EXHIBITS.

          Reference is made to the Exhibit Index filed herewith.

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 the 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 percent change in the

<PAGE>

     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 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 reports filed with or furnished to the
     Commission 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.

          (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 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.

          (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 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 of 1933 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 of 1933 and will be governed by the final adjudication of
     such issue.

     The opinion as to the legality of the securities registered hereunder is
     being given by Kevin Bloomfield, Vice President, Secretary and General
     Counsel of the Registrant. Mr. Bloomfield owns shares of the Company's
     common stock, holds options to purchase shares of such common stock,
     restricted stock units and performance shares and participates in the
     Company's employee benefit plans.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 145(a) of the General Corporation Law of the State of Delaware
     ("Delaware Corporation Law") provides, in general, that a 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, suit or proceeding, whether civil, criminal, administrative or
     investigative (other than an action by or in the right of the corporation),
     because the person is or was a director or officer of the corporation. Such
     indemnity may be against expenses (including attorneys' fees), judgments,
     fines and amounts paid in settlement actually and reasonably incurred by
     the person in connection with such action, suit or proceeding, if the
     person acted in good faith and in a manner the person reasonably believed
     to be in or not opposed to the best interests of the corporation and if,
     with respect to any criminal action or proceeding, the person did not have
     reasonable cause to believe the person's conduct was unlawful.

          Section 145(b) of the Delaware Corporation Law provides, in general,
     that a 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 suit by or in the right of the corporation to
     procure a judgment in its favor because the person is or was a director or
     officer of the corporation, against any expenses (including attorneys'
     fees) actually and reasonably incurred by the person in connection with the
     defense or settlement of such action or suit if the person acted in good
     faith and in a manner the person reasonably believed to be in or not
     opposed to the best interests of the corporation, except that no
     indemnification shall be made in respect of any claim, issue or matter as
     to which such person shall have been adjudged to be liable to the
     corporation unless and only to the extent that the Court of Chancery or the
     court in which such action or suit was brought shall determine upon
     application that, despite the adjudication of liability but in view of all
     the circumstances of the case, such person is fairly and reasonably
     entitled to indemnity for such expenses which the Court of Chancery or such
     other court shall deem proper.
Section 145(g) of the Delaware Corporation Law provides, in general,
     that a corporation shall have the power to purchase and maintain insurance
     on behalf of any person who is or was a director or officer of the
     corporation against any liability asserted against the person in any such
     capacity, or arising out of the person's status as such, whether or not the
     corporation would have the power to indemnify the person against such
     liability under the provisions of the Delaware Corporation Law. The Company
     has obtained a directors' and officers' liability insurance policy, which
     insures the Company's directors and officers against certain liabilities,
     including liabilities for which the Company may not be able to indemnify
     such persons. The Company has also entered into indemnification agreements
     with certain of its directors and executive officers, which provide for
     indemnification against expenses, judgments, fines and settlements in
     connection with threatened or pending litigation, inquiries or
     investigations that arise out of the director's or officer's acts or
     omissions in his capacity as a director or officer of the Company to the
     extent permitted by Delaware law.

          Article Eight of the Registrant's Restated Certificate of
     Incorporation and Article V of the Registrant's Amended and Restated Bylaws
     provide for indemnification and/or exculpation to the fullest extent
     authorized by the Delaware Corporation Law for any person who is or was a
     director or officer of the Registrant who is or was involved or threatened
     to be made so involved in any proceeding, whether civil, criminal,
     administrative or investigative, by reason of the fact that such person is
     or was serving as a director or officer of the Registrant or was serving at
     the request of the Registrant as a director or officer of any other
     enterprise.

          The foregoing is only a general summary of certain aspects of Delaware
     law and the Registrant's organizational documents dealing with
     indemnification of directors and officers, and does not purport to be
     complete. It is qualified in its entirety by reference to the detailed
     provisions of Section 145 of the Delaware Corporation Law, Article Eight of
     the Registrant's Restated Certificate of Incorporation and Article V of the
     Registrant's Amended and Restated Bylaws.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

          Not applicable.

ITEM 8. EXHIBITS.

          Reference is made to the Exhibit Index filed herewith.

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 the 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 percent 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 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 reports filed with or furnished to the
     Commission 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.

          (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 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.

          (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 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 of 1933 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 of 1933 and will be governed by the final adjudication of
     such issue.
