ARTICLE VI
  STOCKHOLDER ACTION    
    

        1.     Action without Meeting. Except as otherwise provided herein, any action required or permitted to be taken by the
stockholders of the Corporation at any annual or special meeting of stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders and may not be taken or
effected by a written consent of stockholders in lieu thereof. 

        2.     Special Meetings. Except as otherwise required by statute, special meetings of the stockholders of the Corporation may be
called only by the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the Directors then in office. Only those matters set forth in the notice of the
special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation. 

 
 

ARTICLE VII
  DIRECTORS    
    

        1.     General. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors
except as otherwise provided herein or required by law. 

        2.     Election of Directors. Election of Directors need not be by written ballot unless the By-laws of the
Corporation (the "By-laws") shall so provide. 

        3.     Number of Directors; Term of Office. The number of Directors of the Corporation shall be fixed solely and exclusively by
resolution duly adopted from time to time by the Board of Directors. The Directors shall be classified, with respect to the term for which they severally hold office, into three classes, as nearly
equal in number as reasonably possible. The initial Class I Director of the Corporation shall be Norman Dann; the initial Class II Directors of the Corporation shall be William D.
Corneliuson and Timothy J. O'Malley; and the initial Class III Directors of the Corporation shall be Frank A. Katarow and John L. Miclot. The initial Class I Directors shall serve for a
term expiring at the annual meeting of stockholders to be held in 2006, the initial Class II Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2004,
and the initial Class III Directors shall serve for a term expiring at the annual meeting of stockholders to be held in 2005. At each annual meeting of stockholders, Directors elected to
succeed those Directors whose terms expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election. Notwithstanding the foregoing,
the Directors elected to each class shall hold office until their successors are duly elected and qualified or until their earlier resignation or removal. 

        4.     Vacancies. Any and all vacancies in the Board of Directors, however occurring, including, without limitation, by reason of
an increase in size of the Board of Directors, or the death, resignation, disqualification or removal of a Director, shall be filled solely and exclusively by the affirmative vote of a majority of the
remaining Directors then in office, even if less than a quorum of the Board of Directors, and not by the stockholders. Any Director appointed in accordance with the preceding sentence shall hold
office for the remainder of the full term of the class of Directors in which the new directorship was created or the vacancy occurred and until such Director's successor shall have been duly elected
and qualified or until his or her earlier resignation or removal. When the number of Directors is increased or decreased, the Board of Directors shall, subject to Article VII.3 hereof,
determine the class or classes to which the increased or decreased number of Directors shall be apportioned; provided,  however, that no decrease in the
number of Directors shall shorten the term of any incumbent Director. In the event of a vacancy in the Board of
Directors, the remaining Directors, except as otherwise provided by law, shall exercise the powers of the full Board of Directors until the vacancy is filled. 

        5.     Removal. Any Director (including persons elected by Directors to fill vacancies in the Board of Directors) may be removed
from office (i) only with cause and (ii) only by the affirmative vote of 

B-2

 

the
holders of 75% or more of the shares then entitled to vote at an election of Directors. At least forty-five (45) days prior to any meeting of stockholders at which it is
proposed that any Director be removed from office, written notice of such proposed removal and the alleged grounds thereof shall be sent to the Director whose removal will be considered at the
meeting. 

 
 

ARTICLE VIII
  LIMITATION OF LIABILITY    
    

        A Director of the Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a
Director, except for liability (a) for any breach of the Director's duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (c) under Section 174 of the DGCL or (d) for any transaction from which the Director derived an improper personal benefit. If
the DGCL is amended after the effective date of this Certificate 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 extent permitted by the DGCL, as so amended. 

        Any
repeal or modification of this Article VIII by either of (i) the stockholders of the Corporation or (ii) an amendment to the DGCL, shall not adversely affect any
right or protection existing at the time of such repeal or modification with respect to any acts or omissions occurring before such repeal or modification of a person serving as a Director at the time
of such repeal or modification. 

 
 

ARTICLE IX
  AMENDMENT OF BY-LAWS    
    

        1.     Amendment by Directors. Except as otherwise provided by law, the By-laws of the Corporation may be amended or
repealed by the Board of Directors by the affirmative vote of a majority of the Directors then in office. 

        2.     Amendment by Stockholders. The By-laws of the Corporation may be amended or repealed at any annual meeting of
stockholders, or special meeting of stockholders called for such purpose as provided in the By-laws, by the affirmative vote of at least 75% of the outstanding shares entitled to vote on
such amendment or repeal, voting together as a single class; provided, however, that if the Board of
Directors recommends that stockholders approve such amendment or repeal at such meeting of stockholders, such amendment or repeal shall only require the affirmative vote of the majority of the
outstanding shares entitled to vote on such amendment or repeal, voting together as a single class. 

 
 

ARTICLE X
  AMENDMENT OF CERTIFICATE OF INCORPORATION    
    

        The Corporation reserves the right to amend or repeal this Certificate in the manner now or hereafter prescribed by statute and this Certificate, and all rights
conferred upon stockholders herein are granted subject to this reservation. Whenever any vote of the holders of voting stock is required to amend or repeal any provision of this Certificate, and in
addition to any other vote of holders of voting stock that is required by this Certificate or by law, such amendment or repeal shall require the affirmative vote of the majority of the outstanding
shares entitled to vote on such amendment or repeal, and the affirmative vote of the majority of the outstanding shares of each class entitled to vote thereon as a class, at a duly constituted meeting
of stockholders called expressly for such purpose; provided, however, that the affirmative vote of not
less than 75% of the outstanding shares entitled to vote on such amendment or repeal, and the affirmative vote of not less than 75% of the outstanding shares of each class entitled to vote thereon as
a class, shall be required to amend or repeal any provision of Article VI, Article VII, Article VIII, Article IX or Article X of this Certificate.

  ARTICLE I
  Stockholders    
    

        SECTION 1. Annual Meeting. The annual meeting of stockholders (any such meeting being referred to in these
By-laws as an "Annual Meeting") shall be held at the hour, date and place within or without the United States which is fixed by the Board of Directors, which time, date and place may
subsequently be changed at any time by vote of the Board of Directors. If no Annual Meeting has been held for a period of thirteen months after the Corporation's last Annual Meeting, a special meeting
in lieu thereof may be held, and such special meeting shall have, for the purposes of these By-laws or otherwise, all the force and effect of an Annual Meeting. Any and all references
hereafter in these By-laws to an Annual Meeting or Annual Meetings also shall be deemed to refer to any special meeting(s) in lieu thereof. 

        SECTION
2. Notice of Stockholder Business and Nominations. 

	(a)
	Annual
Meetings of Stockholders. 

        (1)   Nominations
of persons for election to the Board of Directors of the Corporation and the proposal of business to be considered by the stockholders may be made at an
Annual Meeting (a) pursuant to the Corporation's notice of meeting, (b) by or at the direction of the Board of Directors or (c) by any stockholder of the Corporation who was a
stockholder of record at the time of giving of notice provided for in this By-law, who is entitled to vote at the meeting, who is present (in person or by proxy) at the meeting and who
complies with the notice procedures set forth in this By-law. In addition to the other requirements set forth in this By-law, for any proposal of business to be considered at
an Annual Meeting, it must be a proper subject for action by stockholders of the Corporation under Delaware law. 

        (2)   For
nominations or other business to be properly brought before an Annual Meeting by a stockholder pursuant to clause (c) of paragraph (a)(1) of this
By-law, the stockholder must have given timely notice thereof in writing to the Secretary of the Corporation. To be timely, a stockholder's notice shall be delivered to the Secretary at
the principal executive offices of the Corporation not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the
preceding year's Annual Meeting; provided, however, that in the event that the date of the Annual Meeting is advanced by more than 30 days before or delayed by more than 60 days after
such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to such Annual Meeting and not later than the close of
business on the later of the 90th day prior to such Annual Meeting or the 10th day following the day on which public announcement of the date of such meeting is first made. Such stockholder's notice
shall set forth (a) as to each person whom the stockholder proposes to nominate for election or reelection as a director, all information relating to such person that is required to be
disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of
1934, as amended (the "Exchange Act") (including such person's written consent to being named in the proxy statement 

C-1

 

as
a nominee and to serving as a director if elected); (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be
brought before the meeting, the reasons for conducting such business at the meeting, any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the
proposal is made, and the names and addresses of other stockholders known by the stockholder proposing such business to support such proposal, and the class and number of shares of the Corporation's
capital stock beneficially owned by such other stockholders; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made
(i) the name and address of such stockholder, as they appear on the Corporation's books, and of such beneficial owner, and (ii) the class and number of shares of the Corporation which
are owned beneficially and of record by such stockholder and such beneficial owner. 

        (3)   Notwithstanding
anything in the second sentence of paragraph (a)(2) of this By-law to the contrary, in the event that the number of directors to be
elected to the Board of Directors of the Corporation is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors
made by the Corporation at least 85 days prior to the first anniversary of the preceding year's Annual Meeting, a stockholder's notice required by this By-law shall also be
considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary at the principal executive offices of the Corporation not
later than the close of business on the 10th day following the day on which such public announcement is first made by the Corporation. 

	(b)
	General. 

        (1)   Only
such persons who are nominated in accordance with the provisions of this By-law shall be eligible for election and to serve as directors and only such
business shall be conducted at an Annual Meeting as shall have been brought before the meeting in accordance with the provisions of this By-law. The Board of Directors or a designated
committee thereof shall have the power to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the provisions of this
By-law. If neither the Board of Directors nor such designated committee makes a determination as to whether any stockholder proposal or nomination was made in accordance with the
provisions of this By-law, the presiding officer of the Annual Meeting shall have the power and duty to determine whether the stockholder proposal or nomination was made in accordance with
the provisions of this By-law. If the Board of Directors or a designated committee thereof or the presiding officer, as applicable, determines that any stockholder proposal or nomination
was not made in accordance with the provisions of this By-law, such proposal or nomination shall be disregarded and shall not be presented for action at the Annual Meeting. 

        (2)   For
purposes of this By-law, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or
comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act. 

        (3)   Notwithstanding
the foregoing provisions of this By-law, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules
and regulations thereunder with respect to the matters set forth in this By-law. Nothing in this By-law shall be deemed to affect any rights of stockholders to request
inclusion of proposals in the Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act. 

        SECTION
3. Special Meetings. Except as otherwise required by statute, special meetings of the stockholders of the Corporation may be
called only by the Board of Directors acting pursuant to a resolution approved by the affirmative vote of a majority of the Directors then in office. Only those 

C-2

 

matters
set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation. 

        SECTION
4. Notice of Meetings; Adjournments. A notice of each Annual Meeting stating the hour, date and place, if any, of such Annual
Meeting shall be given not less than ten (10) days nor more than sixty (60) days before the Annual Meeting, to each stockholder entitled to vote thereat by delivering such notice to such
stockholder or by mailing it, postage prepaid, addressed to such stockholder at the address of such stockholder as it appears on the Corporation's stock transfer books. 

        Notice
of all special meetings of stockholders shall be given in the same manner as provided for Annual Meetings, except that the notice of all special meetings shall state the purpose
or purposes for which the meeting has been called. 

        Notice
of an Annual Meeting or special meeting of stockholders need not be given to a stockholder if a waiver of notice is executed before or after such meeting by such stockholder or if
such stockholder attends such meeting, unless such attendance was for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting was not
lawfully called or convened. 

        The
Board of Directors may postpone and reschedule any previously scheduled Annual Meeting or special meeting of stockholders and any record date with respect thereto, regardless of
whether any notice or public disclosure with respect to any such meeting has been sent or made pursuant to Section 2 of this Article I of these By-laws or otherwise. In no
event shall the public announcement of an adjournment, postponement or rescheduling of any previously scheduled meeting of stockholders commence a new time period for the giving of a stockholder's
notice under Section 2 of this Article I of these By-laws. 

        When
any meeting is convened, the presiding officer may adjourn the meeting if (a) no quorum is present for the transaction of business, (b) the Board of Directors
determines that adjournment is necessary or appropriate to enable the stockholders to consider fully information which the Board of Directors determines has not been made sufficiently or timely
available to stockholders, or (c) the Board of Directors determines that adjournment is otherwise in the best interests of the Corporation. When any Annual Meeting or special meeting of
stockholders is adjourned to another hour, date or place, notice need not be given of the adjourned meeting other than an announcement at the meeting at which the adjournment is taken of the hour,
date and place, if any, to which the meeting is adjourned and the means of remote communications, if any, by which stockholders and proxyholders
may be deemed to be present in person and vote at such adjourned meeting; provided, however, that if the adjournment is for more than 30 days, or if after the adjournment a new record date is
fixed for the adjourned meeting, notice of the adjourned meeting and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote
at such adjourned meeting shall be given to each stockholder of record entitled to vote thereat and each stockholder who, by law or under the Certificate of Incorporation of the Corporation (as the
same may hereafter be amended and/or restated, the "Certificate") or these By-laws, is entitled to such notice. 

        SECTION
5. Quorum. A majority of the shares entitled to vote, present in person or represented by proxy, shall constitute a quorum at any
meeting of stockholders. If less than a quorum is present at a meeting, the holders of voting stock representing a majority of the voting power present at the meeting or the presiding officer may
adjourn the meeting from time to time, and the meeting may be held as adjourned without further notice, except as provided in Section 5 of this Article I. At such adjourned meeting at
which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally noticed. The stockholders present at a duly constituted meeting may continue to
transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. 

C-3

 

        SECTION
6. Voting and Proxies. Stockholders shall have one vote for each share of stock entitled to vote owned by them of record according
to the stock ledger of the Corporation, unless otherwise provided by law or by the Certificate. Stockholders may vote either (i) in person, (ii) by written proxy or (iii) by a
transmission permitted by §212(c) of the Delaware General Corporation Law ("DGCL"). Any copy, facsimile telecommunication or other reliable reproduction of the writing or
transmission permitted by §212(c) of the DGCL may be substituted for or used in lieu of the original writing or transmission for any and all purposes for which the original writing or
transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission. Proxies shall be
filed in accordance with the procedures established for the meeting of stockholders. Except as otherwise limited therein or as otherwise provided by law, proxies authorizing a person to vote at a
specific meeting shall entitle the persons authorized thereby to vote at any adjournment of such meeting, but they shall not be valid after final adjournment of such meeting. A proxy with respect to
stock held in the name of two or more persons shall be valid if executed by or on behalf of any one of them unless at or prior to the exercise of the proxy the Corporation receives a specific written
notice to the contrary from any one of them. 

        SECTION
7. Action at Meeting. When a quorum is present at any meeting of stockholders, any matter before any such meeting (other than an
election of a director or directors) shall be decided by a majority of the votes properly cast for and against such matter, except where a larger vote is required by law, by the Certificate or by
these By-laws. Any election of directors by stockholders shall be determined by a plurality of the votes properly cast on the election of directors. The Corporation shall not directly or
indirectly vote any shares of its own stock; provided, however, that the Corporation may vote shares which it holds in a fiduciary capacity to the extent permitted by law. 

        SECTION
8. Stockholder Lists. The Secretary or an Assistant Secretary (or the Corporation's transfer agent or other person authorized by
these By-laws or by law) shall prepare and make, at least 10 days before every Annual Meeting or special meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the
examination of any stockholder, for a period of at least ten (10) days prior to the meeting in the manner provided by law. The list shall also be open to the examination of any stockholder
during the whole time of the meeting as provided by law. 

        SECTION
9. Presiding Officer. The Chairman of the Board, if one is elected, or if not elected or in his or her absence, the President,
shall preside at all Annual Meetings or special meetings of stockholders and shall have the power, among other things, to adjourn such meeting at any time and from time to time, subject to Sections 5
and 6 of this Article I. The order of business and all other matters of procedure at any meeting of the stockholders shall be determined by the presiding officer. 

        SECTION
10. Inspectors of Elections. The Corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors to
act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate
is able to act at a meeting of stockholders, the presiding officer shall appoint one or more inspectors to act at the meeting. Any inspector may, but need not, be an officer, employee or agent of the
Corporation. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according
to the best of his or her ability. The inspectors shall perform such duties as are required by the DGCL, including the counting of all votes and ballots. The inspectors may appoint or retain other
persons or entities to assist the inspectors in the performance of the duties of the inspectors. The presiding officer may review all determinations made by the inspectors, and in so doing the
presiding officer shall be entitled to exercise his or her sole judgment and discretion and he or she shall not be bound by any determinations made by the inspectors. All determinations by the
inspectors 

C-4

 

and,
if applicable, the presiding officer, shall be subject to further review by any court of competent jurisdiction. 

 
 

ARTICLE II
  Directors    
    

        SECTION 1. Powers. The business and affairs of the Corporation shall be managed by or under the direction of the
Board of Directors except as otherwise provided by the Certificate or required by law. 

        SECTION
2. Number and Terms. The number of directors of the Corporation shall be fixed solely and exclusively by resolution duly adopted
from time to time by the Board of Directors. The directors shall hold office in the manner provided in the Certificate. 

        SECTION
3. Qualification. No director need be a stockholder of the Corporation. 

        SECTION
4. Vacancies. Vacancies in the Board of Directors shall be filled in the manner provided in the Certificate. 

        SECTION
5. Removal. Directors may be removed from office in the manner provided in the Certificate. 

        SECTION

President or the Secretary. A resignation shall be effective upon receipt, unless the resignation otherwise provides. 

        SECTION
7. Regular Meetings. The regular annual meeting of the Board of Directors shall be held, without notice other than this
Section 7, on the same date and at the same place as the Annual Meeting following the close of such meeting of stockholders. Other regular meetings of the Board of Directors may be held at such
hour, date and place as the Board of Directors may by resolution from time to time determine and publicize by means of reasonable notice given to any director who is not present at the meeting at
which such resolution is adopted. 

        SECTION
8. Special Meetings. Special meetings of the Board of Directors may be called, orally or in writing, by or at the request of a
majority of the directors, the Chairman of the Board, if one is elected, or the President. The person calling any such special meeting of the Board of Directors may fix the hour, date and place
thereof. 

        SECTION
9. Notice of Meetings. Notice of the hour, date and place of all special meetings of the Board of Directors shall be given to each
director by the Secretary or an Assistant Secretary, or in case of the death, absence, incapacity or refusal of such persons, by the Chairman of the Board, if one is elected, or the President or such
other officer designated by the Chairman of the Board, if one is elected, or the President. Notice of any special meeting of the Board of Directors shall be given to each director in person, by
telephone, or by facsimile, electronic mail or other form of electronic communication, sent to his or her business or home address, at least 24 hours in advance of the meeting, or by written
notice mailed to his or her business or home address, at least 48 hours in advance of the meeting. Such notice shall be deemed to be delivered when hand delivered to such address, read to such
director by telephone, deposited in the mail so addressed, with postage thereon prepaid if mailed, dispatched or
transmitted if faxed, telexed or telecopied, or when delivered to the telegraph company if sent by telegram. 

        A
written waiver of notice signed before or after a meeting by a director and filed with the records of the meeting shall be deemed to be equivalent to notice of the meeting. The
attendance of a director at a meeting shall constitute a waiver of notice of such meeting, except where a director attends a meeting for the express purpose of objecting at the beginning of the
meeting to the transaction of any business because such meeting is not lawfully called or convened. Except as otherwise required by law, 

C-5

 

by
the Certificate or by these By-laws, neither the business to be transacted at, nor the purpose of, any meeting of the Board of Directors need be specified in the notice or waiver of
notice of such meeting. 

        SECTION
10. Quorum. At any meeting of the Board of Directors, a majority of the total number of directors shall constitute a quorum for
the transaction of business, but if less than a quorum is present at a meeting, a majority of the directors present may adjourn the meeting from time to time, and the meeting may be held as adjourned
without further notice, except as provided in Section 9 of this Article II. Any business which might have been transacted at the meeting as originally noticed may be transacted at such
adjourned meeting at which a quorum is present. For purposes of this section, the total number of directors includes any unfilled vacancies on the Board of Directors. 

        SECTION
11. Action at Meeting. At any meeting of the Board of Directors at which a quorum is present, the vote of a majority of the
directors present shall constitute action by the Board of Directors, unless otherwise required by law, by the Certificate or by these By-laws. 

        SECTION
12. Action by Consent. Any action required or permitted to be taken at any meeting of the Board of Directors may be taken without
a meeting if all members of the Board of Directors consent thereto in writing or by electronic transmission and the writing or writings or electronic transmission or transmissions are filed with the
records of the meetings of the Board of Directors. Such filing shall be in paper form if the minutes are maintained in paper form and shall be in electronic form if the minutes are maintained in
electronic form. Such consent shall be treated as a resolution of the Board of Directors for all purposes. 

        SECTION
13. Manner of Participation. Directors may participate in meetings of the Board of Directors by means of conference telephone or
other communications equipment by means of which all directors participating in the meeting can hear each other, and participation in a meeting in accordance herewith shall constitute presence in
person at such meeting for purposes of these By-laws. 

        SECTION

By-laws, each Director and Officer shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended
(but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide
prior to such amendment) against any and all Expenses, judgments, penalties, fines and amounts reasonably paid in settlement that are incurred by such Director or Officer or on such Director's or
Officer's behalf in connection with any threatened, pending or completed Proceeding or any claim, issue or matter therein, which such Director or Officer is, or is threatened to be made, a party to or
participant in by reason of such Director's or Officer's Corporate Status, if such Director or Officer acted in good faith and in a manner such Director or Officer reasonably believed to be in or not
opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification
provided by this Section 2 shall continue as to a Director or Officer after he or she has ceased to be a Director or Officer and shall inure to the benefit of his or her heirs, executors,
administrators and personal representatives. Notwithstanding the foregoing, the Corporation shall indemnify any Director or Officer seeking indemnification in connection with a Proceeding initiated by

indemnification or, in the case of Directors, advancement of Expenses under these By-laws in accordance with the provisions set forth herein. 

        SECTION
3. Indemnification of Non-Officer Employees. Subject to the operation of Section 4 of this Article V of
these By-laws, each Non-Officer Employee may, in the discretion of the Board of Directors of the Corporation, be indemnified by the Corporation to the fullest extent authorized
by the DGCL, as the same exists or may hereafter be amended, against any or all Expenses, judgments, penalties, fines and amounts reasonably paid in settlement that are incurred by such
Non-Officer Employee or on such Non-Officer Employee's behalf in connection with any threatened, pending or completed Proceeding, or any claim, issue or matter therein, which
such Non-Officer Employee is, or is threatened to be made, a party to or participant in by reason of such Non-Officer Employee's Corporate Status, if such
Non-Officer Employee acted in good faith and in a manner such Non-Officer Employee reasonably believed to be in or not opposed to the best interests of the Corporation and,
with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 3 shall exist as to a
Non-Officer Employee after he or she has ceased to be a Non-Officer Employee and shall inure to the benefit of his or her heirs, personal representatives, executors and
administrators. Notwithstanding the foregoing, the Corporation may indemnify any Non-Officer Employee seeking indemnification in connection with a Proceeding initiated by such
Non-Officer Employee only if such Proceeding was authorized by the Board of Directors of the Corporation. 

        SECTION
4. Good Faith. Unless ordered by a court, no indemnification shall be provided pursuant to this Article V to a Director, to
an Officer or to a Non-Officer Employee unless a determination shall have been made that such person acted in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the Corporation and, with respect to any criminal Proceeding, such person had no reasonable cause to believe his or her conduct was unlawful. Such determination shall
be made by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board of Directors, (b) a committee comprised of Disinterested Directors, such
committee having been designated by a majority vote of the Disinterested Directors (even though less than a quorum), (c) if there are no such Disinterested Directors, or if a majority of
Disinterested 

C-11

 

Directors
so directs, by independent legal counsel in a written opinion, or (d) by the stockholders of the Corporation. 

        SECTION
5. Advancement of Expenses to Directors Prior to Final Disposition. 

        (a)   The
Corporation shall advance all Expenses incurred by or on behalf of any Director in connection with any Proceeding in which such Director is involved by reason of
such Director's Corporate Status within ten (10) days after the receipt by the Corporation of a written statement from such Director requesting such advance or advances from time to time,
whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Director and shall be preceded or accompanied by an
undertaking by or on behalf of such Director to repay any Expenses so advanced if it shall ultimately be determined that such Director is not entitled to be indemnified against such Expenses.
Notwithstanding the foregoing, the Corporation shall advance all Expenses incurred by or on behalf of any Director seeking advancement of expenses hereunder in connection with a Proceeding initiated
by such Director only if such Proceeding was (i) authorized by the Board of Directors of the Corporation, or (ii) brought to enforce Director's rights to indemnification or advancement
of Expenses under these By-laws. 

        (b)   If
a claim for advancement of Expenses hereunder by a Director is not paid in full by the Corporation within 10 days after receipt by the Corporation of
documentation of Expenses and the required undertaking, such Director may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and if successful in whole
or in part, such Director shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof,
independent legal counsel, or stockholders) to make a determination concerning the permissibility of such advancement of Expenses under this Article V shall not be a defense to the action and
shall not create a presumption that such advancement is not permissible. The burden of proving that a Director is not entitled to an advancement of expenses shall be on the Corporation. 

        (c)   In
any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such
expenses upon a final adjudication that the Director has not met any applicable standard for indemnification set forth in the DGCL. 

        SECTION
6. Advancement of Expenses to Officers and Non-Officer Employees Prior to Final Disposition. 

        (a)   The
Corporation may, at the discretion of the Board of Directors of the Corporation, advance any or all Expenses incurred by or on behalf of any Officer and
Non-Officer Employee in connection with any Proceeding in which such is involved by reason of the Corporate Status of such Officer or Non-Officer Employee upon the receipt by
the Corporation of a statement or statements from such Officer or Non-Officer Employee requesting such advance or advances from time to time, whether prior to or after final disposition of
such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer and Non-Officer Employee and shall be preceded or accompanied by an
undertaking by or on behalf of such to repay any Expenses so advanced if it shall ultimately be determined that such Officer or Non-Officer Employee is not entitled to be indemnified
against such Expenses. 

        (b)   In
any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such
expenses upon a final adjudication that the Officer or Non-Officer Employee has not met any applicable standard for indemnification set forth in the DGCL. 

C-12

 

        SECTION
7. Contractual Nature of Rights. 

        (a)   The
foregoing provisions of this Article V shall be deemed to be a contract between the Corporation and each Director and Officer entitled to the benefits hereof
at any time while this Article V is in effect, and any repeal or modification thereof shall not affect any rights or obligations then existing with respect to any state of facts then or
theretofore existing or any Proceeding theretofore or thereafter brought based in whole or in part upon any such state of facts. 

        (b)   If
a claim for indemnification hereunder by a Director or Officer is not paid in full by the Corporation within 60 days after receipt by the Corporation of a
written claim for indemnification, such Director or Officer may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in
part, such Director or Officer shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof,
independent legal counsel, or stockholders) to make a determination concerning the permissibility of such indemnification under this Article V shall not be a defense to the action and shall not
create a presumption that such indemnification is not permissible. The burden of proving that a Director or Officer is not entitled to indemnification shall be on the Corporation. 

        (c)   In
any suit brought by a Director or Officer to enforce a right to indemnification hereunder, it shall be a defense that such Director or Officer has not met any
applicable standard for indemnification set forth in the DGCL. 

        SECTION
8. Non-Exclusivity of Rights. The rights to indemnification and advancement of Expenses set forth in this
Article V shall not be exclusive of any other right which any Director, Officer, or Non-Officer Employee may have or hereafter acquire under any statute, provision of the
Certificate or these By-laws, agreement, vote of stockholders or Disinterested Directors or otherwise. 

        SECTION
9. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer or
Non-Officer Employee against any liability of any character asserted against or incurred by the Corporation or any such Director, Officer or Non-Officer Employee, or arising
out of any such person's Corporate Status, whether or not the Corporation would have the power to indemnify such person against such liability under the DGCL or the provisions of this
Article V. 

        SECTION
10. Other Indemnification. The Corporation's obligation, if any, to indemnify any person under this Article V as a result
of such person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust, employee benefit plan or enterprise.
