(b)    If upon the occurrence of any Liquidation, the assets and funds thus
distributed among holders of the Series A Preferred Stock shall be insufficient
to permit the payment to such holders of the preferential amounts described in
subsection 2(a) above, then the entire assets and funds of the Corporation
legally available for distribution shall be distributed ratably among holders of
the Series A Preferred Stock in proportion to the amount of such Series A
Preferred Stock owned by each such holder.

distributed among holders of Series A Preferred Stock shall be sufficient to

of Series A Preferred Stock at least twenty (20) days prior to the effective
date of (i) any consolidation or merger of the Corporation with or into any
other corporation or corporations (other than a merger or consolidation in which
the holders of Series A Preferred Stock receive securities of the surviving
corporation having substantially similar rights to the Series A Preferred Stock
and in which the shareholders of the Corporation immediately prior to the
transaction will be the holders of at least a majority of the voting securities
of the surviving corporation immediately after the transaction); (ii) a sale,
conveyance or disposition of all or substantially all of the assets of the
Corporation; or (iii) the effectuation by the Corporation of a transaction or
series of related transactions in which more than 50% of the voting power of the
Corporation is disposed of. The holders of a majority of the Series A Preferred
Stock shall be entitled, by electing prior to the effective date of any of the
foregoing types of transactions, to require the Corporation to treat any such
transaction as if it were a Liquidation and to cause the proceeds of such
transaction, or any property deliverable from such transaction to be distributed
among the holders of Series A Preferred Stock as if such transaction were a
Liquidation.

--------------------------------------------------------------------------------

(4)Voting Provisions. Except as expressly provided herein or as otherwise
required by law, the holders of Series A Preferred Stock will vote together with
the holders of Common Stock, and not as a separate class, on all matters, with
each holder of Series A Preferred Stock entitles to one vote per share.

(5)Protective Provisions. So long as any shares of Series A Preferred Stock
shall remain outstanding, the Corporation shall not, without the affirmative
vote of the holders of at least a majority of the shares of Series A Preferred
Stock at the time outstanding, voting as a single class (i) alter or change the
rights, preferences or privileges of the shares of the Series A Preferred Stock
so as to affect adversely the shares of the Series A Preferred Stock, (ii)
increase the authorized number of shares of the Series A Preferred Stock, or
(iii) do any act or thing which would result in taxation of the holders of

the liquidation value of the Series A Preferred Stock.

(6)No Conversion. The Series A Preferred Stock shall not be convertible into
other shares of the capital stock of the Corporation.

(7)Board Seats. The holders of the Series A Preferred Stock shall have the right
to nominate, in the manner prescribed in the Corporation's bylaws, two (2) of
the candidates for election as director of the Corporation. The holders of the
Series A Preferred Stock, voting as a separate series, shall be entitled to
elect any candidates so nominated. The holders of the Common Stock, voting as a
separate class, shall be entitled to elect that number of directors as shall
equal the total number of director positions as the Board of Directors of the
Corporation shall consist of from time to time, less the number of directors, if
any, nominated and elected by the holders of the Series A Preferred Stock. At
any meeting (or in a written consent in lieu thereof) held for the purpose of
electing directors, the presence in person or by proxy (or the written consent)
of the holders of a majority of the shares of the Series A Preferred Stock then
outstanding shall constitute a quorum of the Series A Preferred Stock for the
election of directors to be elected solely by the holders of the Series A
Preferred Stock. A vacancy in any directorship elected by the holders of the
Series A Preferred Stock shall be filled only by vote or written consent of the
holders of the Series A Preferred Stock. A vacancy in any directorship elected
by the holders of the Common Stock shall be filled only by vote or written
consent of the holders of the Common Stock.

D.    Any or all classes and series of shares, or any part thereof, may be
certificated or uncertificated, as provided under Pennsylvania law, and this
Paragraph 5 shall not be interpreted to limit the authority of the Board of
Directors to issue some or all of any of the classes or series of shares of the
Corporation without certificates. To the extent certificates for shares are
issued, such certificates shall be in the form as set forth in the Corporation's
bylaws. In the case of shares issued without certificates, the Corporation will,
or cause its transfer agent to, within a reasonable time after such issuance,
send the holders of such shares a written statement containing the information
required to be set forth on certificates by the Corporation's bylaws, by these
Articles of Incorporation, or otherwise by applicable law or regulation.

6.Section 1715 of the Pennsylvania Business Corporation Law of 1988, as amended
(the “BCL”) and subchapters E, F, G and H of Chapter 25 of the BCL shall not be
applicable to this Corporation.

7.Except as provided in Section 5.C(7) of these Amended and Restated Articles of
Incorporation, each director of the Corporation shall be elected by a vote of
the majority of the votes cast with respect to that director at any meeting for
the election of directors at which a quorum is present, in accordance with
Section 2-5(d) of the Amended and Restated Bylaws of the Corporation; provided,
that if the number of nominees exceeds the number of directors to be elected,
the directors shall be elected by the vote of a plurality of the votes cast and
entitled to vote on the election of directors in person or by proxy at any such
meeting. For purposes of this Section 7, a vote of the majority of the votes
cast means that the number of shares voted 'for' a director must exceed 50% of
the votes cast with respect to that director.

8.Henceforth, these Amended and Restated Articles of Incorporation shall become
the Corporation's Articles of Incorporation and shall supersede the original
Articles of Incorporation of this Corporation and all amendments thereto.
