         7.       The Corporation is for profit.

         8.       Simultaneously with the effective date of this Amended and
Restated Certificate of Incorporation (the "Effective Date") all issued and
outstanding shares of Common Stock ("Old Common Stock") shall automatically,
without further action on the part of the Corporation or any holder of Old
Common Stock, be and hereby are automatically combined and reclassified (the
"Reverse Split") as follows: each 34,445 shares of Old Common Stock shall be
combined and reclassified as one share of issued and outstanding Common Stock

account of the Reverse Split. Instead, the



Corporation will redeem any fractional shares which results from the Reverse
Split at a price per shares equal to $3.43.

                  Each holder of a certificate or certificates which immediately
prior to the Effective Date represented outstanding shares of Old Common Stock
shall be entitled to receive upon surrender of such Old Common Stock
certificates to the Corporation for cancellation, a certificate or certificates
representing the number of whole shares of New Common Stock into which such
former shares of Old Common Stock formerly represented by such old certificates
so surrendered, are reclassified under the terms hereof. From and after the
Effective Date, certificates representing shares of Old Common Stock are hereby
canceled and shall represent only the right of holders thereof to receive New
Common Stock.

                  The total number of shares of all classes of capital stock
which the Corporation shall have authority to issue is 1,000 shares, all of
which shares, no par value per share, are to be Common Stock.

the Corporation shall have the authority to issue is one thousand (1,000) shares
of New Common Stock, without par value, which shares may be issued from time to
time and (1) may have such voting powers, full or limited, or no voting powers;
(2) may be subject to redemption at such time or times and at such price or
prices; (3) may be entitled to receive dividends (which may be cumulative or
noncumulative) at such rate, or such conditions, and at such times; (4) entitled

other special rights, qualifications, limitations or restrictions thereof; all
as shall hereafter be stated and expressed in the resolution or resolutions
providing for the issuance of New Common Stock from time to time adopted by the
Board of Directors pursuant to authority to do so which is hereby vested in the

         10.      A director of the Corporation shall not be personally liable

fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its shareholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, and (iii) under Section 174 of the General Corporation
Law of Delaware. If the General Corporation Law of Delaware is amended to
authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extend permitted by the General
Corporation Law of Delaware, as so amended. Any repeal or modification of the
foregoing by the shareholders shall not adversely affect any right or protection
of a director of the Corporation existing at the time of such repeal or
modification.

         11.      The Corporation shall indemnify, and upon request shall
advance expenses to, in the manner and to the full extent permitted by law, any
officer or director (or the estate of any such person) who was or is a party to,
or is threatened to be made a party to, any threatened,



pending or complete action, suit or proceeding, whether civil, criminal,
administrative, investigative or otherwise, by reason of the fact that such
person is or was a director or officer of the Corporation, or is or was serving
at the request of the Corporation as a director, officer, partner, trustee or
employee of another corporation, partnership, joint venture, trust or other
enterprise (an "indemnitee). The Corporation may, to the full extent permitted
by law, purchase and maintain insurance on behalf of any such person against any
liability which may be asserted against him or her. To the full extent permitted
by law, the indemnification and advances provided for herein shall include
expenses (including attorneys' fees), judgments, fines and amount paid in
settlement. The indemnification provided herein shall not be deemed to limit the
right of the Corporation to indemnify any other person for any such expenses
(including attorneys' fees), judgments, fines and amounts paid is settlement to
the full extent permitted by law, nor shall it be deemed exclusive of any other
rights to which any person seeking indemnification from the Corporation may be
entitled under any agreement, vote of shareholders or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office. Notwithstanding the foregoing, the
Corporation shall not indemnify any such indemnitee (1) in any proceeding by the
Corporation against such indemnitee; (2) in the event the board of directors
determines that indemnification is not available under the circumstances because
the officer or director has not met the standard of conduct set for the in the
General Corporation Law of Delaware; or (3) if a judgment or other final
adjudication adverse to the indemnitee establishes his liability (i) for any
breach of the duty of loyalty to the Corporation or its shareholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, or (iii) under Section 174 of the General
Corporation Law of Delaware.

         12.      This Amended and Restated Certificate of Incorporation was
duly adopted by written consent of the Board of Directors on September 16, 2002

accordance with the applicable provisions of Sections 141, 228, 242 and 245 of
the General Corporation Law of the State of Delaware.

         IN WITNESS WHEREOF, the undersigned has executed this Amended and
Restated Certificate of Incorporation this 16th day of September, 2002.
