                  Any new business to be conducted at the annual meeting of the
         stockholders shall be stated in writing and filed with the Secretary of
         the corporation on or before thirty (30) days in advance of the first
         anniversary date (month and day) of the previous year's annual meeting,
         and all business so stated, proposed and filed shall, unless prior
         action thereon is required by the Board, be considered at the annual
         meeting. Any stockholder may make any other proposal at the annual

         thirty (30) days in advance of the first anniversary date (month or

         meeting at which it is presented. No other proposal may be acted upon
         at the annual meeting. This provision shall not prevent the
         consideration, approval or disapproval at the annual meeting of the
         reports of officers and committees, but in connection with such reports
         no business shall be acted upon at such annual meeting unless stated
         and filed as herein provided.

stockholders is called shall be given not less than ten (10) nor more than sixty
(60) days before the date of the meeting, either personally or by mail, to each
stockholder of record entitled to vote at such meeting. If mailed, such notice
shall be deemed to be given when deposited in the U.S. mail, postage prepaid,
and addressed to the stockholder at his or her address as it appears on the
records of the corporation as of the record date prescribed in Section 3.9.1 and
Section 11.1.1 of these Bylaws.

         Section 3.4       Nominations For Director. Nominations of candidates
for election as directors at any meeting of stockholders may be made: (a) by, or
at the direction of, a majority of the Corporate Governance and Nominating
Committee of the Board, or, if there is no Corporate Governance and Nominating
Committee of the Board at such time, by a majority of the Board; or (b) by any
stockholder of record entitled to vote at such meeting; provided that only
persons nominated in accordance with procedures set forth in this Section shall
be eligible for election as directors.

         Nominations, other than those made by, or at the direction of, the
Corporate Governance and Nominating Committee or the Board, may only be made
pursuant to timely notice in writing to the Secretary of the corporation as set
forth in this Section 3.4. To be timely, a stockholder's notice shall be
delivered to, or mailed and received by the Secretary of the corporation, for an
annual meeting, not less than sixty (60) days nor more than ninety (90) days in
advance of the first anniversary date (month and day) of the previous year's
annual meeting, and for a special meeting, not less than sixty (60) days nor
more than ninety (90) days in advance of the date (month and day) of the special
meeting, regardless of any postponement or adjournments of that meeting to a
later date. Such stockholder notice shall set forth: (a) as to each person whom
the stockholder proposes to nominate for election as a director: (i) the name,
age, business address and residential address of such person; (ii) the principal
occupation or employment of such person; (iii) the class and number of shares of
the corporation's stock which are beneficially owned by such person on the date
of such stockholder notice; and (iv) any other information relating to such
person that would be required to be disclosed on Schedule 13D pursuant to
Regulation 13D-G under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), in connection with the acquisition of stock, and pursuant to

                                       2

                                         Bylaws of Centrue Financial Corporation
                                                     As Amended on July 24, 2007



Regulation 14A under the Exchange Act, in connection with the solicitation of
proxies with respect to nominees for election as directors, regardless of
whether such person is subject to the provisions of such regulations, including,
but not limited to, information required to be disclosed by Items 4(b) and 6 of
Schedule 14A of Regulation 14A with the Securities and Exchange Commission; and
(b) as to the stockholder giving the notice: (a) the name and address, as they
appear on the corporation's books, of such stockholder and the name and
principal business or residential address of any other beneficial stockholders
known by such stockholder to support such nominees; and (b) the class and number
of shares of the corporation's stock which are beneficially owned by such
stockholder on the date of such stockholder notice and the number of shares
owned beneficially by any other record or beneficial stockholders known by such
stockholder to be supporting such nominees on the date of such stockholder
notice. At the request of the Corporate Governance and Nominating Committee or
the Board, any person nominated by, or at the request of, the Corporate
Governance and Nominating Committee or the Board for election as a director
shall furnish to the Secretary of the corporation that information required to
be set forth in a stockholder's notice of nomination which pertains to the
nominee.

         The Corporate Governance and Nominating Committee or the Board may
reject any nomination by a stockholder not timely made in accordance with the
requirements of this Section 3.4. If the Corporate Governance and Nominating
Committee or the Board determines that the information provided in a
stockholder's notice does not satisfy the informational requirements of this
Section 3.4 in any material respect, the Secretary of the corporation shall
promptly notify such stockholder of the deficiency in the notice. The
stockholder may cure the deficiency by providing additional information to the
Secretary within such period of time, not less than five days from the date such
deficiency notice is given to the stockholder, as the Corporate Governance and
Nominating Committee or the Board shall determine. If the deficiency is not
cured within such period, or if the Corporate Governance and Nominating
Committee or the Board determines that the additional information provided by
the stockholder, together with information previously provided, does not satisfy
the requirements of this Section 3.4 in any material respect, then the Corporate
Governance and Nominating Committee or the Board may reject such stockholder's
notice and the proposed nominations shall not be accepted if presented at the
stockholder meeting to which the notice relates. The Secretary of the
corporation shall notify a stockholder in writing whether his or her nomination
has been made in accordance with the time and informational requirements of this
Section 3.4. Notwithstanding the procedure set forth in this Section 3.4, if
neither the Corporate Governance and Nominating Committee nor the Board makes a
determination as to the validity of any nominations by a stockholder, the
presiding officer of the stockholder's meeting shall determine and declare at
the meeting whether a nomination was not made in accordance with the terms of
this Section 3.4. If the presiding officer determines that a nomination was not
made in accordance with the terms of this Section 3.4, he or she shall so
declare at the meeting and the defective nomination shall not be accepted.

         Section 3.5       Special Meetings. Special meetings of stockholders
for the purpose of taking any action permitted the stockholders by law and the
Certificate of Incorporation of this corporation may be called at any time by at
least 66 2/3% of directors then in office. Except in special cases where other
express provision is made by statute, notice of such special meetings shall be
given in the same manner as for annual meetings of stockholders.

                                                     As Amended on July 24, 2007


         Section 3.6       Voting Lists. The officer having charge of the stock
transfer books for shares of the capital stock of the corporation shall make at
least ten (10) days before each meeting of the stockholders a complete list of
the stockholders entitled to vote at such meeting, with the address of and the
number of shares registered in the name of, each stockholder. Such list shall be
subject to inspection by any stockholder, for any purpose germane to the
meeting, at any time during the meeting, either at a place within the city where
the meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified in the notice of the meeting, at the place
where the meeting is to be held. Such list shall also be produced and kept open
at the time and place of the meeting and shall be subject to the inspection of
any stockholder during the whole time of the meeting. The original stock
transfer books shall be prima facie evidence as to who are the stockholders
entitled to examine such list or transfer books or to vote at any meeting of
stockholders.

         Section 3.7       Quorum. A majority of the shares entitled to vote,
represented in person or by proxy, shall constitute a quorum for the transaction
of business at a meeting of the stockholders. The stockholders present at a duly
called or held meeting at which a quorum is present may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.

         Section 3.8       Adjourned Meeting and Notice Thereof. Any
stockholders' meeting, annual or special, whether or not a quorum is present,
may be adjourned from time to time by the vote of a majority of the shares
present, whether in person or represented by proxy, but in the absence of a
quorum no other business may be transacted at such meeting, except as provided
in Section 3.7 above. When any stockholders' meeting, either annual or special,
is adjourned for more than thirty (30) days, or if after the adjournment a new
record date is fixed for the adjourned meeting, notice of the adjourned meeting
shall be given to each stockholder of record entitled to vote at the meeting.
Except as provided above, it shall not be necessary to give any notice of the
adjourned meeting if the time and place thereof are announced at the meeting at
which such adjournment is taken.

         Section 3.9       Voting.

                  3.9.1    Record Date. Unless a record date for voting purposes
         is fixed as provided in Section 11.1.1 of these Bylaws then, subject to
         the provisions of Section 217 of the General Corporation Law of the
         State of Delaware (the "Delaware General Corporation Law") (relating to
         voting of shares held by fiduciaries, pledgors and joint owners), only
         persons in whose names shares entitled to vote stand on the stock
         records of the corporation at the close of business on the business day
         next preceding the day on which notice of the meeting is given or, if
         such notice is waived, at the close of business on the business day
         next preceding the day on which the meeting of stockholders is held,
         shall be entitled to vote at such meeting, and such day shall be the
         record date for such meeting.

                                         Bylaws of Centrue Financial Corporation
                                                     As Amended on July 24, 2007


                  3.9.2    Method; Vote Required. Unless otherwise required by
         law, voting may be oral or by written ballot; provided, however, that
         all elections for directors must be by ballot if demanded by a
         stockholder before such voting begins. Except as provided in Section
         3.7 and except with respect to election of directors, the affirmative
         vote of the majority of the shares represented and voting at a duly
         held meeting at which a quorum is present (which shares voting
         affirmatively also constitute at least a majority of the required
         quorum) shall be the act of the stockholders, unless the vote of a
         greater number or voting by classes is required by the Delaware General
         Corporation Law or the Certificate of Incorporation or these Bylaws.
         Directors shall be elected by a plurality of the votes of the shares
         present in person or represented by proxy at the meeting and entitled
         to vote on the election of directors.

                  3.9.3    Voting of Shares by Certain Holders. Shares standing
         in the name of another corporation may be voted by any officer, agent
         or proxy as the bylaws of such corporation may prescribe, or, in the
         absence of such provision, as the board of directors of such
         corporation may determine. Shares held by an administrator, executor,
         guardian or conservator may be voted by him or her, either in person or
         by proxy, without a transfer of such shares into his or her name.
         Shares standing in the name of a trustee may be voted by the trustee,
         either in person or by proxy, but no trustee shall be entitled to vote
         shares held by him or her without a transfer of such shares into the
         trustee's name.

                  Neither treasury shares of its own stock held by the
         corporation, nor shares held by another corporation, if a majority of
         the shares entitled to vote for the election of directors of such other
         corporation are held directly or indirectly by the corporation, shall
         be voted at any meeting or counted in determining the total number of
         outstanding shares at any given time for purposes of any meeting.

         Section 3.10      Conduct of Meeting. The presiding officer at any
meeting of stockholders, either annual or special, shall be the Chairman of the
Board or, in his or her absence, the President or, in the absence of both the
Chairman of the Board and the President, anyone selected by a majority of the
Board. The secretary at such meetings shall be the Secretary of the corporation
or, in his or her absence, anyone appointed by the presiding officer.

         Section 3.11      Proxies. At all meetings of the stockholders, every
stockholder having the right to vote shall be entitled to vote in person or by
proxy appointed by an instrument in writing and complying with the requirements
of the Delaware General Corporation Law. No proxy shall be valid after the
expiration of three (3) years from the date thereof unless otherwise provided in
the proxy. A duly executed proxy shall be irrevocable if it states that it is
irrevocable and if, and only so long as, it is coupled with an interest in the
stock of the corporation or in the corporation generally which is sufficient in
law to support an irrevocable power.

         Section 3.12      Inspectors of Election. In advance of any meeting of
stockholders, the Board may appoint any persons other than nominees for office
as inspectors of election to act at such meeting or any adjournment thereof. If
inspectors of election are not so appointed, or if any persons so appointed fail
to appear or refuse to act, the presiding officer of any such meeting may, and
on the request of any stockholder or a stockholder's proxy shall, make such

appointment at the meeting. The number of inspectors shall be either one or
three. If appointed at a meeting on the request of one or more stockholders or
proxies, the majority of shares represented in person or by proxy shall
determine whether one or three inspectors are to be appointed. The duties of
such inspectors shall include: (a) determining the number of shares of stock and
the voting power of each share, the shares of stock represented at the meeting,
the existence of a quorum, and the authenticity, validity and effect of the
proxies; (b) receiving votes, ballots or consents; (c) hearing and determining
all challenges and questions in any way arising in connection with the right to
vote; (d) counting and tabulating all votes or consents; (e) determining the
result; and (f) such acts as may be proper to conduct the election or vote with
fairness to all stockholders.

                                   ARTICLE IV
                                    DIRECTORS

         Section 4.1       Powers. Subject to any limitations imposed by law,
the Certificate of Incorporation and these Bylaws as to actions which shall be
authorized or approved by the stockholders, and subject to the duties of
directors as prescribed thereby, the business and affairs of the corporation
shall be managed and all corporate powers shall be exercised by or under the
direction of the Board.

         Section 4.2       Number and Qualifications. (a) The exact number of
directors shall be fixed from time to time by the Board pursuant to a resolution
adopted of not less than 66 2/3 % of the number of directors which immediately
prior to such change had been fixed, in the manner prescribed herein, by the
Board, subject to the provisions of the Certificate of Incorporation of the
corporation.

         (b)      Notwithstanding any other provisions of the Certificate of
Incorporation of the corporation or these bylaws (and notwithstanding the fact
that some lesser percentage may be specified by law, the certificate of
incorporation or these bylaws of the corporation), any director or the entire
board of directors of the corporation may be removed at any time, but only for
cause and only by the affirmative vote of the holders of not less than 66 2/3 %
of the outstanding shares of stock of the corporation entitled to vote generally
in the election of directors (considered for this purpose as one class) cast at
an annual meeting of stockholders or at a meeting of the stockholders called for
that purpose.

         Section 4.3       Election and Vacancies. Each class of directors to be
elected shall be elected at the annual meeting of the stockholders of the
corporation and shall hold office until their successors are elected and
qualified or until their earlier death, resignation or removal. Any director may
resign at any time upon written notice to the corporation. Thereafter, directors
who are elected at an annual meeting of stockholders, and directors who are
elected in the interim to fill vacancies and newly created directorships, shall
hold office until the next annual meeting of stockholders at which directors of
such class are to be elected and until their successors are elected and
qualified or until their earlier death, resignation or removal. In the interim
between annual meetings of stockholders or of special meetings of stockholders
called for the election of directors and/or for the removal of one or more
directors and for the filling of any vacancy in that connection, newly created
directorships and any vacancies in the board of directors, including vacancies

resulting from the removal of directors, may be filled by the vote of a majority
of the remaining directors then in office, although less than a quorum, or by
the sole remaining director.

         Section 4.4       Regular Meetings. The Board shall meet regularly at
the time and place designated in a resolution of the Board or by written consent
of all members of the Board, whether within or without the State of Delaware,
and no notice of such regular meetings need be given to the directors.

         Section 4.5       Organization Meeting. Following each annual meeting
of stockholders, the Board shall hold a regular meeting at the place of said
annual meeting or at such other place as shall be fixed by the Board, for the
purpose of organization, election of officers, and the transaction of other
business. Call and notice of such meetings are hereby dispensed with.

         Section 4.6       Special Meetings. Special meetings of the Board may
be called by the Chairman of the Board, the President, the Chief Executive
Officer, the Secretary, or any two directors. Notice of each such meeting shall
be given to each director by the Secretary or by the person or persons calling
the meeting. Such notice shall specify the time and place of the meeting, which
may be within or without the State of Delaware, and the general nature of the
business to be transacted, and no other business may be transacted at the
meeting. Such notice shall be deposited in the mail, postage prepaid, at least
four (4) days prior to the meeting, directed to the address of the director on
the records of the corporation, or delivered in person or by telephone or
telegram, telecopy or other means of electronic transmission to the director at
least 48 hours before the meeting. Notice of a meeting need not be given to any
director who signs a waiver of notice or a consent to holding the meeting, or an
approval of the minutes thereof, whether before or after such meeting, or who
attends the meeting without protesting, prior thereto or at its commencement,
the lack of notice to such director. All such waivers, consents and approvals
shall be filed with the corporate records or made a part of the minutes of the
meeting.

         Section 4.7       Quorum; Majority Action. A majority of the authorized
number of directors shall constitute a quorum for the transaction of business at
any meeting of the Board, but if less than such majority is present at a
meeting, a majority of the directors present may adjourn the meeting from time
to time. Notice of any adjourned meeting shall be given in the same manner as
prescribed in Section 4.6 of these Bylaws. Every act or decision of a majority
of the directors present at a meeting at which a quorum is present, made or done
at a meeting duly held, shall be valid as the act of the Board, unless a greater
number is required by law or the Certificate of Incorporation or these Bylaws.

         Section 4.8       Action Without Meeting. Any action required or
permitted to be taken by the Board or a committee of the Board may be taken
without a meeting if all members of the Board or a committee of the Board shall
individually or collectively consent in writing to such action. Such written
consent or consents shall be filed with the minutes of the proceedings of the
Board and shall have the same force and effect as a unanimous vote of the Board.

         Section 4.9       Telephonic Meetings. Members of the Board may
participate in any regular or special meeting, including meetings of committees
of the Board, through use of conference telephone or similar communications

equipment, so long as all members participating in such meeting can hear one
another. Participation in a meeting pursuant to this section constitutes
presence in person at such meeting.

         Section 4.10      Fees and Compensation. Fees and compensation of
directors and members of committees for their services, and reimbursement for
expenses, shall be fixed or determined by a resolution of the Board after
considering recommendations of the Corporate Governance and Nominating
Committee. Nothing herein contained shall be construed to preclude any director
from serving the corporation in any other capacity as an officer, employee,
agent or otherwise, and receiving compensation therefor.

         Section 4.11      Removal. A director may be removed only for cause as
determined by the affirmative vote of the holders of at least 66 2/3% of the
shares then entitled to vote in an election of directors, which vote may only be
taken at an annual meeting or a special meeting. Cause for removal shall be
deemed to exist only if the director whose removal is proposed has been
convicted of a felony by a court of competent jurisdiction or has been adjudged
by a court of competent jurisdiction to be liable for gross negligence or
misconduct in the performance of such director's duty to the corporation and
such adjudication is no longer subject to direct appeal.

         Section 4.12      Directors Emeritus/Advisory Directors. The Board of
Directors may by resolution appoint directors emeritus or advisory directors who
shall have such authority and receive such compensation and reimbursement as the
Board of Directors shall provide. Directors emeritus or advisory directors shall

         Section 6.1       Committees of the Board. (1) The Board may designate
one or more committees, each consisting of three or more directors of the

by majority vote of the Independent Directors then in office.

         (3)      The Board may, by a resolution adopted by a majority of the
authorized number of directors, but shall not be required to, designate an
Executive Committee consisting of three or more directors, one of which shall be
the Chairman of the Board or the Chief Executive Officer, to serve at the
pleasure of the Board. If an Executive Committee is designated, it shall have,

         classes or any other series of the same or any other class or classes
         of stock of the corporation or fix the number of shares of any series
         of stock or authorize the increase or decrease of the shares of any
         series);

         under Sections 251 or 252 of the Delaware General Corporation Law;

                  (c)      Recommending to the stockholders the sale, lease or
         exchange of all or substantially all of the corporation's property and
         assets;

                  (d)      Recommending to the stockholders a dissolution of the

         stock or to adopt a certificate of ownership and merger pursuant to
         Section 253 of the Delaware General Corporation Law.

         (4)      A committee may by resolution fix the regular meeting date of
such committee, and notice of any such regular meeting date shall be dispensed
with. Special meetings of a committee may be held at the principal office of the
corporation, or at any place which has been designated from time to time by
resolution of the committee or by written consent of all members thereof.
Committee meetings may be called by the Board, by the Chairman of the Board, by
the CEO of the corporation, by the chair of the committee or any two or more
members of such committee. Written notice to the members of a committee of the
time and place of such special meeting shall be given in the manner provided for
the giving of written notice to members of the Board of the time and place of
special meetings of the Board. Vacancies in the membership of a committee may be
filled by the Board. A majority of the authorized number of members of a
committee shall constitute a quorum for the transaction of business; and
transactions of any meeting of a committee, however called and noticed, or
wherever held, shall be as valid as though at a meeting duly held after regular
call and notice, if a quorum is present and if, either before or after the
meeting, each of the members not present signs a written waiver of notice or a
consent to holding such meeting or an approval of the minutes thereof. All such
waivers, consents or approvals shall be filed with the corporation's records or
made a part of the minutes of the meeting.

         Section 7.1       Indemnification.

                  7.1.1    Actions, Suits or Proceedings other than by or in the
         Right of the Corporation. The corporation shall 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

                                       11

         civil, criminal, administrative or investigative (other than an action
         by or in the right of the corporation) by reason of the fact that he or
         she is or was a director, officer, employee or agent of the
         corporation, or is or was serving at the request of the corporation as
         a director, officer, employee or agent of another corporation,
         partnership, joint venture, trust or other enterprise, or by reason of
         any action alleged to have been taken or omitted in such capacity,
         against expenses (including attorneys' fees), judgments, fines and
         amounts paid in settlement actually and reasonably incurred by him or
         her or on his or her behalf in connection with such action, suit or
         proceeding and any appeal therefrom, if he or she 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 action or proceeding, had no reasonable cause to believe his
         or her conduct was unlawful. The termination of any action, suit or
         proceeding by judgment, order, settlement, conviction, or upon a plea
         of nolo contendere or its equivalent, shall not, of itself, create a
         presumption that the person did not act in good faith and in a manner
         which he or she reasonably believed to be in, or not opposed to, the
         best interests of the corporation and, with respect to any criminal
         action or proceeding, had reasonable cause to believe that his or her
         conduct was unlawful.

                  7.1.2    Actions or Suits by or in the right of the
         Corporation. The corporation shall 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 by reason of the fact that he or she is
         or was a director, officer, employee or agent of the corporation or is
         or was serving or has agreed to serve at the request of the corporation
         as a director, officer, employee or agent of another corporation,
         partnership, joint venture, trust or other enterprise, or by reason of
         any action alleged to have been taken or omitted in such capacity,
         against expenses (including attorneys' fees) actually and reasonably
         incurred by him or her or on his or her behalf in connection with the
         defense or settlement of such action or suit and any appeal therefrom,
         if he or she 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, 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 of Delaware or the court in which such
         action or suit was brought shall determine upon application that,
         despite the adjudication of such liability but in view of all the
         circumstances of the case, such person is fairly and reasonably
         entitled to indemnity for such costs, charges and expenses which the
         Court of Chancery or such other court shall deem proper.

                  7.1.3    Indemnification for Costs, Charges and Expenses of
         Successful Party. Notwithstanding the other provisions of this Section
         7.1, to the extent that a director, officer, employee or agent has been
         successful, on the merits or otherwise, including, without limitation,
         to the extent permitted by applicable law, the dismissal of an action
         without prejudice, in defense of any action, suit or proceeding
         referred to in Sections 7.1.1 and 7.1.2, or in defense of any claim,
         issue or matter therein, he or she shall be indemnified against all
         costs, charges and expenses (including attorneys' fees) actually and
         reasonably incurred by him or her or on his or her behalf in connection
         therewith.

                                                     As Amended on July 24, 2007


                  7.1.4    Determination of Right to Indemnification. Any
         indemnification under Sections 7.1.1 and 7.1.2, (unless ordered by a
         court) shall be paid by the corporation, if a determination is made (a)
         by the board of directors by a majority vote of the directors who were
         not parties to such action, suit or proceeding, or (b) if such majority
         of disinterested directors so directs, by independent legal counsel in
         a written opinion, or (c) by the stockholders, that indemnification of
         the director or officer is proper in the circumstances because he or
         she has met the applicable standard of conduct set forth in Sections
         7.1.1 and 7.1.2.

                  7.1.5    Advance of Costs, Charges and Expenses. Expenses
         (including attorneys' fees) incurred by a person referred to in
         Sections 7.1.1 and 7.1.2 in defending a civil, criminal, administrative
         or investigative action, suit or proceeding shall be paid by the
         corporation in advance of the final disposition of such action, suit or
         proceeding; provided, however, that the payment of such costs, charges
         and expenses incurred by a director or officer in his or her capacity
         as a director or officer (and not in any other capacity in which
         service was or is rendered by such person while a director or officer)
         in advance of the final disposition of such action, suit or proceeding
         shall be made only upon receipt of an undertaking by or on behalf of
         the director or officer to repay all amounts so advanced in the event
         that it shall ultimately be determined that such director or officer is
         not entitled to be indemnified by the corporation as authorized in this
         Article VII. Such costs, charges and expenses incurred by other
         employees and agents may be so paid upon such terms and conditions, if
         any, as the majority of the directors deems appropriate. The majority
         of the directors may, in the manner set forth above, and upon approval
         of such director or officer of the corporation, authorize the
         corporation's counsel to represent such person, in any action, suit or
         proceeding, whether or not the corporation is a party to such action,
         suit or proceeding.

                  7.1.6    Procedure for Indemnification. Any indemnification
         under Sections 7.1.1, 7.1.2 and 7.1.3, or advance of costs, charges and
         expenses under Section 7.1.5, shall be made promptly, and in any event
         within 60 days, upon the written request of the director, officer,
         employee or agent. The right to indemnification or advances as granted
         by this Article VII shall be enforceable by the director, officer,
         employee or agent in any court of competent jurisdiction, if the
         corporation denies such request, in whole or in part, or if no
         disposition thereof is made within 60 days. Such person's costs and
         expenses incurred in connection with successfully establishing his or
         her right to indemnification, in whole or in part, in any such action
         shall also be indemnified by the corporation. It shall be a defense to
         any such action (other than an action brought to enforce a claim for
         the advance of costs, charges and expenses under Section 7.1.5, where
         the required undertaking, if any, has been received by the corporation)
         that the claimant has not met the standard of conduct set forth in
         Sections 7.1.1 and 7.1.2, but the burden of proving such defense shall
         be on the corporation. Neither the failure of the corporation
         (including its board of directors, its independent legal counsel and
         its stockholders) to have made a determination prior to the
         commencement of such action that indemnification of the claimant is
         proper in the circumstances because he or she has met the applicable
         standard of conduct set forth in Sections 7.1.1 and 7.1.2, nor the fact
         that there has been an actual determination by the corporation

                                                     As Amended on July 24, 2007


         (including its board of directors, its independent legal counsel and
         its stockholders) that the claimant has not met such applicable
         standard of conduct, shall be a defense to the action or create a
         presumption that the claimant has not met the applicable standard of
         conduct.

                  7.1.7    Settlement. The corporation shall not be obligated to
         reimburse the costs of any settlement to which it has not agreed. If in
         any action, suit or proceeding, including any appeal, within the scope
         of Sections 7.1.1 and 7.1.2, the person to be indemnified shall have
         unreasonably failed to enter into a settlement thereof offered or
         assented to by the opposing party or parties in such action, suit or
         proceeding, then, notwithstanding any other provision hereof, the
         indemnification obligation of the corporation to such person in
         connection with such action, suit or proceeding shall not exceed the
         total of the amount at which settlement could have been made and the
         expenses incurred by such person prior to the time such settlement
         could reasonably have been effected.

         Section 7.2       Subsequent Amendment. No amendment, termination or
repeal of this Article VII or of relevant provisions of the Delaware General
Corporation Law or any other applicable law shall affect or diminish in any way
the rights of any director or officer of the corporation to indemnification
under the provisions hereof with respect to any action, suit or proceeding
arising out of, or relating to, any actions, transactions or facts occurring
prior to the final adoption of such amendment, termination or repeal.

         Section 7.3       Other Rights; Continuation of Right to
Indemnification. The indemnification provided by this Article VII shall not be
deemed exclusive of any other rights to which a director, officer, employee or
agent seeking indemnification may be entitled under any law (common or
statutory), agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in his or her official capacity and as to action in
any other capacity while holding office or while employed by or acting as agent
for the corporation, and shall continue as to a person who has ceased to be a
director, officer, employee or agent, and shall inure to the benefit of the
estate, heirs, executors and administrators of such person. Nothing contained in
this Article VII shall be deemed to prohibit, and the corporation is
specifically authorized to enter into, agreements with officers and directors
providing indemnification rights and procedures different from those set forth
herein. All rights to indemnification under this Article VII shall be deemed to
be a contract between the corporation and each director or officer of the
corporation who serves or served in such capacity at any time while this Article
VII is in effect. The corporation shall not consent to any acquisition, merger,
consolidation or other similar transaction unless the successor corporation
assumes by operation of law or by agreement the obligations set forth in this
Article VII.

         Section 7.4       Insurance. The corporation shall have the power to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against any liability asserted against him or her and incurred by him or her in
any such capacity, or arising out of his or her status as such, whether or not

the corporation would have the power to indemnify him or her against such
liability under this Article VII.

         Section 7.5       Certain Definitions.  For purposes of this Article
VII:

                  (i)      references to "the corporation" shall include, in
         addition to the resulting corporation, any constituent corporation

Section 11.1      Record Date.

         11.1.1 Stockholders Meetings. In order that the corporation may
determine the stockholders entitled to notice of or to vote at any meeting of
stockholders or adjournment thereof, the Board may fix, in advance, a record
date, which shall not be more than sixty (60) nor less than ten (10) days before
the date of such meeting. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; provided, however, that the Board may fix a new record date for
the adjourned meeting.

         11.1.2 Other Actions. In order that the corporation may determine the
stockholders entitled to receive payment of any dividend or other distribution
or allotment of any rights or the stockholders entitled to exercise any rights
in respect of any change, conversion or exchange of stock, the Board may fix, in
advance, a record date, which shall not be more than sixty (60) days prior to
such action.

         11.1.3 Subsequent Transfers and Closing Transfer Books. When a record
date is fixed, only stockholders of record at the close of business on that date
are entitled to notice and to vote or to receive the dividend, distribution or
allotment of rights or to exercise the rights, as the case may be,
notwithstanding any transfer of any shares on the books of the corporation after
the record date, except as otherwise provided in the Certificate of
Incorporation or by agreement or in the Delaware General Corporation Law. The
Board may close the books of the corporation against transfers of shares during
the whole, or any part, of any such period.

Section 11.2      Inspection of Corporate Records.

         11.2.1 By Stockholders. Any stockholder, in person or by attorney or
other agent, shall, upon written demand under oath stating the purpose thereof,
have the right during the usual hours of business to inspect for any proper
purpose the corporation's stock ledger, a list of its stockholders, and its
other books and records, and to make copies or extracts therefrom. A proper
purpose shall mean a purpose reasonably related to such person's interest as a
stockholder. In every instance where an attorney or other agent shall be the
person who seeks the right to inspection, the demand under oath shall be
accompanied by a power of attorney or such other writing which authorizes the
attorney or other agent to so act on behalf of the stockholder.

         11.2.2 By Directors. Each director shall have the right at any
reasonable time to inspect all books, records, documents of every kind, and the
physical properties of the corporation. The inspection may be made in person or
by agent or attorney, and the right of inspection includes the right to make
extracts and copies thereof.

         Section 11.3      Corporate Seal. The corporate seal of the
corporation, if any, shall be in such form as the Board shall prescribe.
