     Section 1.02. Other Offices. The Corporation also may have offices at such other places both within and without the State of Delaware as the Board of Directors may from time to time determine.

II. STOCKHOLDERS

     Section 2.01. Place of Meetings. Meetings of stockholders may be held at the principal executive offices of the Corporation or at such other place, either within or without the State of Delaware, as may be designated by the Board of Directors or the chief executive officer of the Corporation.

     Section 2.02. Annual Meetings and Advance-Notice of Business, Other than Director Nominations and Elections. An annual meeting of stockholders shall be held in each calendar year for the election of directors on such date and at such time as shall be designated from time to time by the Board of Directors. At any annual meeting of stockholders of the Corporation, the proposal of business (other than the nomination and election of directors, which shall be subject to Section 3.13) to be considered by the stockholders may be made (i) pursuant to the Corporation’s notice of the meeting (or any supplement thereto), (ii) by or at the direction of the Board of Directors, or (iii) by any stockholder of record of the Corporation entitled to vote on the business at the meeting who complies with the notice procedures hereinafter set forth in this Section.

     (a) Timing of Notice. For such business to be properly brought before any annual meeting by a stockholder, a stockholder’s notice of any such business to be conducted at such meeting must be delivered to the Secretary of the Corporation, or mailed to and received at the principal executive office of the Corporation, not less than one hundred twenty (120) days before the first anniversary of the date of the preceding year’s annual meeting of stockholders. If, however, the date of the annual meeting of stockholders is more than thirty (30) days before or sixty (60) days after such anniversary date, notice by a stockholder shall be timely only if so delivered or so mailed and received not less than one hundred twenty (120) days before such annual meeting or, if later, within ten (10) days after the first public announcement of the date of such annual meeting. Except to the extent otherwise required by law, the adjournment of an annual meeting of stockholders shall not commence a new time period for the giving of a stockholder’s notice as required above. Nothing in this Section shall reduce or otherwise affect the notice period required under Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) in order for a stockholder to have the right, under Rule 14a-8, to include or have disseminated or described in the Corporation’s proxy statement or on the proxy card of the Board of Directors for any annual meeting of stockholders any stockholder proposal.

     (b) Content of Notice. A stockholder’s notice to the Corporation for an annual meeting of stockholders shall set forth as to each matter the stockholder proposes to bring before the annual meeting (i) a brief description of the business desired to be brought before the meeting and the reasons for conducting such business at the meeting, (ii) the name and address, as they appear on the Corporation’s books, of the stockholder proposing such business and the name and address of any

beneficial owner on whose behalf the proposal is made, (iii) the information required by clause (b)(y)(ii) of Section 3.13 with respect to such stockholder and any such beneficial owner, (iv) any material interest in such business of the stockholder or any such beneficial owner, and (v) a representation and other appropriate evidence that the stockholder is a holder of record of shares of stock entitled to vote on such business at the meeting, will continue to be a holder of record of shares of stock entitled to vote on such business through the date of the meeting, and intends to appear in person or by proxy at the meeting to make the proposal.

     (c) Consequences of Failure to Give Proper Notice. Notwithstanding anything in these By-Laws to the contrary, no business (other than the nomination and election of directors, which shall be subject to Section 3.13) shall be conducted at any annual meeting except in accordance with the procedures set forth in this Section. The presiding Officer of the meeting shall, if the facts warrant, determine that business was not properly brought before the meeting in accordance with the procedures described in this Section and, if the presiding Officer should so determine, the presiding Officer shall so declare to the meeting, and any such business not properly brought before the meeting shall not be transacted. Nothing in this Section shall be deemed to preclude discussion by any stockholder of any business properly brought before the meeting in accordance with these By-Laws.

     (d) Public Announcement. For purposes of this Section and Section 3.13, “public announcement” means disclosure (i) when made in a press release reported by the Dow Jones News Service, Associated Press, or comparable national news service, (ii) when filed 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, or (iii) when mailed as the notice of the meeting (or any supplement) pursuant to Section 2.04 of the By-Laws.

     (e) Compliance with Laws. Notwithstanding the foregoing provisions of this Section, a stockholder shall also comply with all applicable requirements of Delaware law and the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section and in Section 3.13.

     Section 2.03. Special Meetings. Unless otherwise specifically provided by law or the Certificate of Incorporation, a special meeting of stockholders, for any purpose or purposes, may be called only by the Chairman or the President and shall be called by either such officer upon the written request of a majority of the Board of Directors or by a committee of the Board of Directors which has been duly designated by the Board of Directors, and whose powers and authority, as expressly provided in a resolution of the Board of Directors, include the power to call such meetings. Such request shall state the purpose or purposes of the proposed meeting. If the authorized officers fail to cause such meeting to be called within thirty (30) days after receipt of such request and held within ninety (90) days after receipt of such request, the directors making the request may call the meeting by giving notice as provided in these By-Laws at the expense of the Corporation. Business transacted at any special meeting shall be limited to the purposes stated in the notice of the meeting.

     Section 2.04. Notice of Meetings. A written notice stating the place, date and hour of the meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, or a separate written notice of the posing of such information on an electronic network (such as a website), shall be personally delivered or mailed, postage prepaid, not less than ten (10) nor more than sixty (60) days before the date of such meeting to each stockholder of record of the Corporation entitled to vote at such meeting at the stockholder’s mailing address shown upon the records of the Corporation. Service of notice is complete upon mailing.

     Section 2.05. Waiver of Notice. Notice of any annual or special meeting of stockholders may be waived either before, at or after such meeting in a writing signed by the person or persons entitled to the notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transacting of any business because the meeting is not lawfully called or convened.

     Section 2.06. Quorum. At each meeting of stockholders, except where otherwise provided by law or the Certificate of Incorporation or these By-Laws, the holders of a majority of the outstanding capital stock entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum. If a quorum is once present at the meeting, the stockholders may continue to transact business until adjournment notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

     Section 2.07. Adjourned Meetings. The stockholders present, though less than a quorum, may, by majority vote, adjourn the meeting from time to time to a later day or hour or to another place. If the adjournment is for more than thirty (30) days, or if after adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. Otherwise, notice of any adjourned meeting need not be given if the time and place thereof are announced at the meeting at which the adjournment is taken. At an adjourned meeting at which a quorum is present or represented by proxy, any business may be transacted which might have been transacted at the meeting as originally convened.

     Section 2.08. Voting. Unless otherwise provided in the Certificate of Incorporation, each stockholder entitled to vote at any meeting of stockholders shall have one vote for each share of stock having voting power upon the matter in question which is held by such stockholder and registered in the stockholder’s name on the books of the Corporation as of the applicable record date. All elections of directors shall be conducted by written ballot, unless the Certificate of Incorporation otherwise provides. The vote upon any other question before a meeting need not be by written ballot, and need not be conducted by inspectors, unless otherwise determined by the Board of Directors or the officer presiding at the meeting. At all meetings of stockholders for the election of directors a plurality of the votes cast shall be sufficient to elect such directors. All other elections and questions at a meeting shall be decided by a majority vote of the number of shares entitled to vote represented at the meeting at the time of the vote except where otherwise required by statute, the Certificate of Incorporation or these By-Laws.

     Section 2.09. Proxies. Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for him or her by proxy in any manner, including without limitation via telephone, Internet or such other manner as permitted by Section 212 of the Delaware General Corporation Law, as amended from time to time, provided that such authorization sets forth or contains information from which the Corporation can determine that the authorization was granted by the stockholder. If the authorization is granted in a manner other than in a written form, the proxy holder shall provide such reasonable verification as required by the Corporation. If any such authorization designates two or more persons to act as proxies, a majority of such persons present at the meeting, or, if only one shall be present, then that one, shall have and may exercise all of the powers conferred by such authorization upon all of the persons so designated unless such authorization shall otherwise provide.

     Section 2.10. Fixing Date for Determination of Stockholders of Record.

     (a) In order that the Corporation may determine the stockholders entitled (i) to notice of or to vote at any meeting of stockholders or any adjournment thereof, or (ii) to express consent to corporate action in writing without a meeting, or (iii) to receive payment of any dividend or other distribution or allotment of any rights, or to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action, the Board of Directors may fix,

in advance, a record date, which shall be (X) not more than sixty (60) nor less than ten (10) days before the date of any such meeting; (Y) not more than ten (10) days after the date upon which the resolution fixing the record date for any written action is adopted by the Board of Directors; and (Z) not more than sixty (60) days prior to any other action.

     (b) If no record date is fixed:

     (i) The record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held.

     (ii) The record date for determining stockholders entitled to express consent to corporate action in writing without a meeting, (A) when no prior action by the Board of Directors is necessary, shall be the day on which the first signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation, and (B) when prior action by the Board of Directors is necessary, shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

     (iii) The record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

     (c) 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 of Directors may fix a new record date for the adjourned meeting.

     Section 2.11. Stockholder List. The officer of the Corporation who has charge of the stock ledger of the Corporation shall prepare and make, at least ten (10) days before every 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 any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to 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, at the place where the meeting is to be held. The list also shall be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. The stock ledger shall be the only evidence as to who are the stockholders entitled to examine the stock ledger, the list of stockholders or the books of the Corporation, or to vote in person or by proxy at any meeting of stockholders.

of such special meeting. Except to the extent otherwise required by law, the adjournment of a meeting of stockholders shall not commence a new time period for the giving of a stockholder’s notice as described above. Nothing in this Section shall reduce or otherwise affect the notice period required under Rule 14a-11 under the Exchange Act, if such Rule 14a-11 becomes effective, in order for a stockholder to have the right, under Rule 14a-11, to include or have disseminated or described in the Corporation’s proxy statement or on the proxy card of the Board of Directors for any meeting of stockholders any nomination by any stockholder or stockholders of a director or directors.

     (b) Content of Notice.

     (c) Consequences of Failure to Give Proper Notice. Notwithstanding anything in these By-Laws to the contrary, no stockholder-sponsored nominees shall be eligible for election as a director of the Corporation except in accordance with the procedures set forth in this Section. The presiding Officer of the meeting shall, if the facts warrant, determine that the nomination(s) were not properly brought before the meeting in accordance with the procedures described in this Section and, if the presiding Officer should so determine, the presiding Officer shall so declare to the meeting, and the defective nomination(s) shall be disregarded.

     (iii) the stockholders of the Corporation approve a definitive agreement or plan to (A) merge or consolidate the Corporation with or into another corporation (other than (1) a merger or consolidation with a subsidiary of the Corporation, or (2) a merger in which the Corporation is the surviving corporation and no outstanding voting stock of the Corporation (other than fractional shares) held by stockholders immediately prior to the merger is converted into cash, securities, or other property), (B) exchange, pursuant to a statutory exchange of shares of voting stock of the Corporation held by stockholders of the Corporation immediately prior to the exchange, shares of one or more classes or series of voting stock of the Corporation for shares of another corporation, (C) sell or otherwise dispose of all or substantially all of the assets of the Corporation (in one transaction or a series of transactions), or (D) liquidate or dissolve the Corporation, unless a majority of the voting stock (or the voting equity interest) of the surviving corporation or of any corporation (or other entity) acquiring all or substantially all of the assets of the Corporation (in the case of a merger, consolidation or disposition of assets) or the Corporation (in the case of a statutory share exchange) is, immediately following the merger, consolidation, statutory share exchange or disposition of assets, beneficially owned by the person seeking indemnification or a group of persons, including the person seeking indemnification, acting in concert; or

     (iv) the Corporation enters into an agreement in principle or a definitive agreement relating to an event described in clause (i), (ii) or (iii) above which ultimately results in an event described therein, or a tender or exchange offer or proxy contest is commenced which ultimately results in an event described therein.

     Section 5.04. Good Faith Defined, Etc. For purposes of any determination of whether a person is entitled to indemnification, such person shall be deemed to have 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, or, with respect to any criminal action or proceeding, to have had no reasonable cause to believe his or her conduct was unlawful, if such person relied on the records or books of account of the Corporation or other enterprise, or on information supplied to him or her by the officers of the Corporation or other enterprise, or on information or records given or reports made to the Corporation or other enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Corporation or other enterprise. The term “other enterprise” as used in this Section 5.04 shall mean any enterprise other than the Corporation, including any corporation, partnership, joint venture, trust, employee benefit plan or other enterprise as to which such person is or was serving at the request of the Corporation as a director, officer, employee, agent or trustee. The provisions of this Section 5.04 shall not be deemed to be exclusive or to limit in any way the circumstances in which a person may be deemed to have met the applicable standard of conduct set forth in Section 145 of the Delaware General Corporation Law, as amended from time to time.

     Section 5.05. Right to Indemnification Upon Application; Procedure Upon Application; Etc.

     (a) Any indemnification under these By-Laws shall be made no later than forty-five (45) days after receipt by the Corporation of the written request of the director or officer, or former director or officer, unless a determination is made within said 45-day period in accordance with Section 5.03 that such person has not met the applicable standard of conduct.

     (b) The right to indemnification or expense advances under these By-Laws shall be enforceable by the director or officer, or former director or officer, in any court of competent jurisdiction. Following a Change in Control (as defined in Section 5.03(c)), the burden of proving that indemnification is not appropriate shall be on the Corporation. Neither the absence of any prior determination that indemnification is proper in the circumstances, nor a prior determination that indemnification is not proper in the circumstances, shall be a defense to the action or create a presumption that the director or officer, or former director or officer, has not met the applicable standard of conduct. The expenses (including attorneys’ fees and expenses) incurred by the director or officer, or former director or officer, in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action (or in any action or claim brought by him or her to recover under any insurance policy or policies referred to in Section 5.02) also shall be indemnified by the Corporation.

     (c) If any person is entitled under any provision of these By-Laws to indemnification by the Corporation for some or a portion of expenses, judgments, fines, penalties or amounts paid in settlement incurred by him or her, but not, however, for the total amount thereof, the Corporation shall nevertheless indemnify such person for the portion of such expenses, judgments, fines, penalties and amounts to which he or she is entitled.

     Section 5.06. Certain Persons Not Entitled to Indemnification. Notwithstanding any other provision of these By-Laws, no person shall be entitled to indemnification or expense advances under these By-Laws with respect to any action, suit, proceeding or claim brought or made by him or her against the Corporation, other than an action, suit, proceeding or claim seeking, or defending such person’s right to, indemnification and/or expense advances pursuant to these By-Laws or otherwise.

     Section 5.07. Non-Exclusivity and Survival of Indemnification. Except as otherwise provided in Section 5.06, but notwithstanding any other provision of these By-Laws, it is the policy of the Corporation that indemnification and expense advances shall be made to the fullest extent permitted by law, and, accordingly, in the event of any change in law, by legislation or otherwise, permitting greater indemnification and/or expense advances, the provisions of these By-Laws shall be construed so as to

require such greater indemnification and/or expense advances. The provisions of these By-Laws shall not be deemed to preclude the indemnification of any person whom the Corporation has the power to indemnify under the provisions of the General Corporation Law of the State of Delaware or otherwise. All rights to indemnification and advancement of expenses under these By-Laws shall be deemed to be provided by a contract between the Corporation and the director or officer who serves in such capacity at any time while these By-Laws are in effect. Any repeal or modification of the indemnification provisions of these By-Laws shall not affect any rights or obligations then existing. The Corporation may provide additional indemnification rights to a director or officer of the Corporation by separate agreement.

     Section 5.08. Successors; Meaning of “Corporation”. The indemnification provisions of these By-Laws shall be binding upon and enforceable against any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Corporation. For purposes of these By-Laws, but subject to the provisions of any agreement relating to any merger or consolidation of the kind referred to in clause (a) below or of any agreement relating to the acquisition of any corporation of the kind referred to in clause (b) below, references to “the Corporation” shall include (a) any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger with the Corporation which, if its separate existence had continued, would have had power and authority to indemnify its directors and officers, so that any person who is or was a director or officer of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or trustee of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, shall stand in the same position under the provisions of these By-Laws with respect to the Corporation as he or she would have with respect to such constituent corporation if its separate existence had continued; and (b) any corporation of which at least a majority of the voting power (as represented by its outstanding stock having voting power generally in the election of directors) is owned directly or indirectly by the Corporation.

     Section 5.09. Severability. The indemnification provisions of these By-Laws shall be severable in the event that any provision hereof (including any provision within a single section, subsection, clause, paragraph or sentence) is held invalid, void or otherwise unenforceable on any ground by any court of competent jurisdiction. In the event of any such holding, the remaining indemnification provisions of these By-Laws shall continue in effect and be enforceable to the fullest extent permitted by law.

VI. STOCK

     Section 6.01. Certificated and Uncertificated Shares. Shares of stock of the Corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution or resolutions that some or all of any or all classes or series of stock may be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Corporation. Certificates representing shares shall be in such form as shall be prescribed by the Board of Directors, certifying the number of shares owned by the holder. Shares represented by certificates shall be numbered in the order in which they shall be issued and shall be signed in the name of the Corporation by the Chairman, the President or a Vice-President, and by the Treasurer or an Assistant Treasurer, or the Secretary or an Assistant Secretary, and the seal of the Corporation, if any, shall be affixed thereto.

     Section 6.02. Issuance of Stock. The Board of Directors is authorized to cause to be issued stock of the Corporation up to the full amount authorized by the Certificate of Incorporation in such amounts and for such consideration as may be determined by the Board of Directors. No shares shall be allotted except in consideration of cash, labor, personal property, or real property, or leases thereof, or of an amount transferred from surplus to stated capital upon a stock dividend. At the time of such allotment of stock, the Board of Directors shall state its determination of the fair value to the Corporation in monetary terms of any consideration other than cash for which shares are allotted. The amount of consideration to be

received in cash or otherwise shall not be less than the par value of the shares so allotted. Stock so issued shall be fully paid and nonassessable. Treasury shares may be disposed of by the Corporation for such consideration as may be fixed by the Board of Directors.

     Section 6.03. Partly Paid Stock. The Corporation may issue the whole or any part of its stock as partly paid and subject to call for the remainder of the consideration to be paid therefor. Upon the face or back of each certificate issued to represent any such partly paid stock, or upon the stock ledger in the case of uncertificated shares, the total amount of the consideration to be paid therefor and the amount paid thereon shall be stated. The Board of Directors may, from time to time, demand payment in respect of each share of stock not fully paid, of such sum of money as the necessities of the business may, in the judgment of the Board of Directors, require, not exceeding in the whole the balance remaining unpaid on such stock, and such sum so demanded shall be paid to the Corporation at such times and by such installments as the Board of Directors shall direct.

     Section 6.04. Registered Stockholders. The Corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of Delaware.

     Section 6.05. Transfers of Stock. Transfers of stock shall be made on the books of the Corporation only by the record holder of such stock, or such holder’s legal representative or duly authorized attorney-in-fact, and, in the case of stock represented by a certificate, upon surrender of the certificate or the certificates for such stock. Upon surrender to the Corporation or the transfer agent of the Corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignation or authority to transfer, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. No new certificate or certificates shall be issued in exchange for any existing certificate until such certificate shall have been so cancelled, except in cases provided for in Section 6.06.

     Section 6.06. Lost, Stolen or Destroyed Certificates. Any stockholder claiming a certificate for stock to be lost, stolen or destroyed shall make an affidavit of that fact in such form as the Corporation may require and shall, if the Corporation so requires, give the Corporation a bond of indemnity in form, in an amount, and with one or more sureties satisfactory to the Corporation, to indemnify the Corporation against any claims which may be made against it on account of the alleged loss, theft or destruction of the certificate or issuance of such new certificate. A new certificate may then be issued in the same tenor and for the same number of shares as the one claimed to have been lost, stolen or destroyed.

     Section 6.07. Facsimile Signatures. Whenever any certificate is countersigned by a transfer agent or by a registrar other than the Corporation or one of its employees, then the signatures of the officers or agents of the Corporation may be facsimiles. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed on any such certificate shall cease to be such officer, transfer agent or registrar before such certificate is issued, it nevertheless may be issued by the Corporation as though the person who signed such certificate or whose facsimile signature or signatures had been placed thereon were such officer, transfer agent or registrar at the date of issue.

VII. MISCELLANEOUS

     Section 7.01. Dividends. The Board of Directors may declare at any regular or special meeting dividends from the Corporation’s surplus, or if there be none, out of its net profits for the current fiscal year and/or the preceding fiscal year, in such amounts as in their opinion the condition of the affairs of the

Corporation shall render it advisable unless otherwise restricted by law. Dividends may be paid in cash, in property or in shares of capital stock of the Corporation, subject to the provisions of the Certificate of Incorporation.

     Section 7.02. Interested Directors and Officers. No contract or transaction between the Corporation and one or more of its directors or officers, or between the Corporation and any other corporation, partnership, association or other organization in which one or more of its directors or officers are directors or officers, or have a financial interest, shall be void or voidable solely for that reason, or solely because the director or officer is present at or participates in the meeting of the Board of Directors or committee thereof which authorizes the contract or transaction, or solely because his, her or their votes are counted for such purpose, if: (a) the material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the Board of Directors or the committee, and the Board of Directors or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (b) the material facts as to his or her relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (c) the contract or transaction is fair as to the Corporation as of the time it is authorized, approved or ratified, by the Board of Directors, a committee thereof, or the stockholders. Common or interested directors may be counted in determining the presence of a quorum at a meeting of the Board of Directors or of a committee which authorizes the contract or transaction.

     Section 7.03. Voting Securities Held by the Corporation. Unless otherwise ordered by the Board of Directors, powers of attorney, proxies, waivers of notice of meeting, consents and other instruments relating to securities owned by the Corporation may be executed in the name of and on behalf of the Corporation by the Chairman or the President, and either such officer may, in the name of and on behalf of the Corporation, take all such action as such officer may deem advisable to vote in person or by proxy at any meeting of security holders of other corporations in which the Corporation may hold securities, and at any such meeting such officer shall possess and may exercise any and all rights and powers incident to the ownership of such securities that the Corporation might have possessed and exercised if it had been present. The Board of Directors may from time to time confer like powers upon any other person or persons.

     Section 7.04. Execution of Instruments.

     (a) All deeds, mortgages, bonds, checks, contracts and other instruments pertaining to the business and affairs of the Corporation shall be signed on behalf of the Corporation by the Chairman, the President or any Vice President, or by such other person or persons as may be designated from time to time by the Board of Directors.

     (b) If a document must be executed by persons holding different offices or functions and one person holds such offices or exercises such functions, that person may execute the document in more than one capacity if the document indicates each such capacity.

     Section 7.05. Advances. The Corporation may, without a vote of the directors, advance money to its directors, officers or employees to cover expenses that can reasonably be anticipated to be incurred by them in the performance of their duties and for which they would be entitled to reimbursement in the absence of an advance.

     Section 7.06. Fiscal Year. The fiscal year end of the Corporation shall be September 30 or such other date as may be fixed from time to time by resolution of the Board of Directors.

     Section 7.07. Corporate Seal. The corporate seal, if one is adopted by the Board of Directors, shall be circular in form and shall have inscribed thereon the name of the Corporation, the word “Delaware” and the words “Corporate Seal.” The seal may be used by causing it or a facsimile thereof to be impressed or affixed or reproduced or otherwise placed on any document requiring it.

     Section 7.08. Power to Amend. These By-Laws may be altered, amended or repealed or new By-Laws may be adopted as provided in the Certificate of Incorporation of the Corporation.
