STERIGENICS FLORIDA ACQUISITION CORP.

ARTICLE I. MEETINGS OF SHAREHOLDERS

Section 1. Annual Meeting. The annual meeting of the shareholders of the Corporation for the election of directors and the transaction of other business shall be held each year and on the date and at the time and place that the board of directors determines. If any annual meeting is not held, by oversight or otherwise, a special meeting shall be held as soon as practical, and any business transacted or election held at that meeting shall be as valid as if transacted or held at the annual meeting.

Section 2. Special Meetings. Special meetings of the shareholders for any purpose shall be held when called by the president or the board of directors, or when demanded in writing by the holders of not less than ten percent (unless a greater percentage not to exceed 50 percent is required by the articles of incorporation) of all the shares entitled to vote at the meeting. Such demand must be delivered to the Corporation’s secretary. A meeting demanded by shareholders shall be called for a date not less than ten nor more than 60 days after the request is made, unless the shareholders requesting the meeting designate a later date. The secretary shall issue the call for the meeting, unless the president, the board of directors, or shareholders requesting the meeting designate another person to do so. The shareholders at a special meeting may transact only business that is related to the purposes stated in the notice of the special meeting.

Section 3. Place. Meetings of shareholders may be held either within or outside the State of Florida.

Section 4. Shareholder Action. Any action required or permitted to be taken at any annual or special meeting of the shareholders of the Corporation may be taken (i) upon the vote of shareholders at a duly convened meeting of shareholders in accordance with the Articles of Incorporation and these By-Laws, or (ii) upon written consent of the shareholders as provided in Section 607.0704 of the Florida Business Corporation Act.

Section 5. Notice. A written notice of each meeting of shareholders, stating the place, day, and time of the meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered to each shareholder of record entitled to vote at the meeting, not less than ten nor more than sixty days before the date set for the meeting, either personally or by first-class mail, by or at the direction of the president, the secretary, or the officer or other persons calling the meeting. If mailed, the notice shall be considered delivered when it is deposited in the United States mail, postage prepaid, addressed to the shareholder at his address as it appears on the records of the Corporation.

Section 6. Waivers of Notice. Whenever any notice is required to be given to any shareholder of the Corporation under these bylaws, the articles of incorporation, or the Florida Business Corporation Act, a written waiver of notice, signed anytime by the person entitled to notice shall be equivalent to giving notice. Attendance by a shareholder entitled to vote at a meeting, in person or by proxy, shall constitute a waiver of (a) notice of the meeting, except when the shareholder attends a meeting solely for the purpose, expressed at the beginning of the meeting, of objecting to the transaction of any business because the meeting is not lawfully called or convened, and (b) an objection to consideration of a particular matter at the meeting that is not within the purpose of the meeting unless the shareholders object to considering the matter when it is presented.

Section 7. Shareholder Quorum and Voting. A majority of the shares entitled to vote, represented in person (whether by teleconference or telephone) or by proxy, constitutes a quorum at a meeting of shareholders. If a quorum is present, the affirmative vote of a majority of the shares entitled to vote on the matter is the act of the shareholders unless otherwise provided by law. A shareholder may vote either in person or by proxy executed in writing by the shareholder or shareholder’s duly authorized attorney-in-fact. After a quorum has been established at a shareholders’ meeting, a withdrawal of shareholders that reduces the number of shareholders entitled to vote at the meeting below the number required for a quorum does not affect the validity of an adjournment of the meeting or an action taken at the meeting prior to the shareholders’ withdrawal. Presence at a meeting for the purposes of determining a quorum and voting may be in person (which shall include presence by electronic means such as video conferencing, telephone or any other electronic media wherein all shareholders participating may simultaneously hear each other) or by proxy.

Authorized but unissued shares including those redeemed or otherwise reacquired by the corporation, and shares of stock of the Corporation owned by another corporation or other entity the majority of the voting stock of which is owned or controlled by the Corporation, directly or indirectly, at any meeting shall not be counted in determining the total number of outstanding shares at any time. The chairman of the board, the president, any vice president, the secretary, and the treasurer of a corporate shareholder are presumed to possess, in that order, authority to vote shares standing in the name of a corporate shareholder, absent a bylaw or other instrument of the corporate shareholder designating some other officer, agent, or proxy to vote the shares. Shares held by an administrator, executor, guardian, or conservator may be voted by that person without a transfer of the shares into his or her name. A trustee may vote shares standing in the trustee’s name, but no trustee may vote shares that are not transferred into the trustee’s name. If a receiver is authorized to do so by an appropriate order of the court by which he was appointed, the receiver may vote shares standing in his or her name or held by or under his control, without transferring the shares into his or her name. A shareholder whose shares are pledged may vote the shares until the shares have been transferred into the name of the pledgee, and thereafter the pledgee or his nominee shall be entitled to vote the shares unless the instrument creating the pledge provides otherwise.

ARTICLE II. DIRECTORS

Section 1. Function. The business of the Corporation shall be managed and its corporate powers exercised by the board of directors.

Section 2. Number. The initial Board of Directors will consist of one (1) director. The number of directors may be increased or decreased from time to time by action of the shareholders, but no decrease shall have the effect of shortening the term of any incumbent director, unless the shareholders remove the director.

Section 3. Qualification. Each member of the board of directors must be a natural person who is eighteen years of age or older. A director need not be a resident of Florida or a shareholder of the Corporation.

Section 4. Election and Term. The incorporator, by written consent, shall elect the members of the initial board of directors who shall hold office until the first annual meeting of shareholders and until their successors have been elected and qualified or until their earlier resignation, removal from office, or death. At the first annual meeting of shareholders and at each annual meeting thereafter the shareholders shall elect directors to hold office until the next succeeding annual meeting. Each director shall hold office for the term for which he or she is elected and until his or her successor is elected and qualifies or until his or her earlier resignation, removal from office, or death.

Section 5. Compensation.

a. The board of directors has authority to fix the compensation of the directors, as directors and as officers. A director may receive a salary from the Corporation for his or her services to the Corporation. Such salary shall be deducted from income of the Corporation. The compensation shall be adjusted periodically as necessary to provide reasonable compensation. Such salary and adjustments shall be established by agreement of the shareholders, which agreement may include bonuses and commissions. If a director for any reason ceases to be a director of the Corporation, the party will no longer be entitled to receive a salary.

b. The board of directors may charge the Corporation for any direct expenses reasonably incurred by the board of directors in connection with the Corporation’s business if established by agreement of the shareholders.

Section 6. Duties of Directors. A director shall perform his or her duties as a director, including his duties as a member of any committee of the board upon which he or she serves, in good faith, in a manner he or she reasonably believes to be in the best interests of the Corporation.

Section 7. Presumption of Assent. A director of the Corporation who is present at a meeting of the board of directors or a committee of the board of directors when corporate action is taken is presumed to have assented to the action unless he votes against it or expressly abstains from voting on the action taken, or, the director objects at the beginning of the meeting to the holding of the meeting or transacting specific business at the meeting.

Section 8. Vacancies. Unless filled by the shareholders, any vacancy occurring in the board of directors, including any vacancy created because of an increase in the number of directors, may be filled by the affirmative vote of a majority of the remaining directors, even if the number of remaining directors does not constitute a quorum of the board of directors. A director elected to fill a vacancy shall hold office only until the next election of directors by the shareholders.

Section 9. Removal or Resignation of Directors. At a meeting of shareholders called for that purpose, the shareholders, by a vote of the holders of a majority of the shares entitled to vote at an election of directors, may remove any director, or the entire board of directors, with or without cause, and fill any vacancy or vacancies created by the removal.

A director may resign at any time by delivering written notice to the board of directors or its chairman or the corporation. A resignation is effective when the notice is delivered unless the notice specifies later effective date. If a resignation is made effective at a later date, the board of directors may fill the pending vacancy before the effective date if the board of directors provided that the successor does not take office until the effective date.

Section 10. Quorum and Voting. A majority of the board of directors constitutes a quorum for the transaction of business. The act of the majority of the directors at a meeting at which a quorum is present (whether by telephone or teleconference) is the act of the board of directors. Presence at a meeting for the purposes of determining a quorum and voting shall be in person (which shall include presence by electronic means such as video conferencing, telephone or any other electronic media wherein all directors participating may simultaneously hear each other).

Section 11. Place of Meetings. Regular and special meetings by the board of directors may be held within or outside the State of Florida.

Section 12. Regular Meetings. A regular meeting of the board of directors shall be held without notice, other than this bylaw, immediately after and at the same place as the annual meeting of shareholders. The board of directors may provide, by resolution, the time and place for the holding of additional regular meetings without notice other than the resolution.

Section 13. Special Meetings. Special meetings of the board of directors may be called by or at the request of the president or any directors.

Section 14. Notice of Meetings. Written notice of the time and place of special meetings of the board of directors shall be given to each director by either personal delivery or by first class United States mail, telegram, or cablegram at least two days before the meeting. Notice of a meeting of the board of directors need not be given to any director who signs a waiver of notice either before or after the meeting. Attendance of a director at a meeting constitutes a waiver of notice of the meeting and all objections to the time and place of the meeting, or the manner in which it has been called or convened, except when the director states, at the beginning of the meeting, or promptly upon arrival at the meeting, any objection to the transaction of business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the board of directors need be specified in the notice or waiver of notice of the meeting.

A majority of the directors present, whether or not a quorum exists, may adjourn any meeting of the board of directors to another time and place. Notice of any adjourned meeting shall be given to the directors who were not present at the time of the adjournment and, unless the time and place of the adjourned meeting are announced at the time of the adjournment, to the other directors.

Section 15. Action Without a Meeting. Any action required or permitted to be taken at a Board of Directors’ meeting or a meeting of any committee of the Board of Directors may be taken without a meeting if: (a) each of the directors, or each of the members of the committee, as the case may be, consents in writing to the action; (b) the consent sets forth the action to be taken; and (c) the consent is filed in the minutes of the proceedings of the Board or of the committee. The consents may consist of one or more writings and such written consents of the Board of Directors shall have the same effect as a unanimous meeting vote.

ARTICLE III. OFFICERS

Section 1. Officers. The officers of the Corporation shall consist of a president, secretary and treasurer, and may include one or more vice presidents, one or more assistant secretaries, and one or more assistant treasurers. The officers shall be elected initially by the board of directors at the organizational meeting of board of directors and thereafter at the first meeting of the board following the annual meeting of the shareholders in each year. The board from time to time may elect or appoint other officers, assistant officers, and agents, who shall have the authority and perform the duties prescribed by the board. An elected or duly appointed officer may, in turn, appoint one or more officers or assistant officers, unless the board of directors disapproves or rejects the appointment. All officers shall hold office until their successors have been appointed and have qualified or until their earlier resignation, removal from office, or death. One person may simultaneously hold any two or more offices. The failure to elect a president, secretary, or treasurer shall not affect the existence of the Corporation.

Section 2. President. The president, subject to the directions of the board of directors, is responsible for the general and active management of the business and affairs of the Corporation, has the power to sign certificates of stock, bonds, deeds, and contracts for the Corporation, and shall preside at all meetings of the shareholders.

Section 3. Vice Presidents. Each vice president has the power to sign bonds, deeds, and contracts for the Corporation and shall have the other powers and perform the other duties prescribed by the board of directors or the president. Unless the board otherwise provides, if the president is absent or unable to act, the vice president who has served in that capacity for the longest time and who is present and able to act shall perform all the duties and may exercise any of the powers of the president. Any vice president may sign, with the secretary or assistant secretary, certificates for stock of the Corporation.

Section 4. Secretary. The secretary shall have the power to sign contracts and other instruments for the Corporation and shall (a) keep the minutes of the proceedings of the shareholders and the board of directors in one or more books provided for that purpose, (b) see that all notices are duly given in accordance with the provisions of these bylaws or as required by law, (c) maintain custody of the corporate records and the corporate seal, attest the signatures of officers who execute documents on behalf of the Corporation, authenticate records of the Corporation, and assure that the seal is affixed to all documents of which execution on behalf of the Corporation under its seal is duly authorized, (d) keep a register of the post office address of each shareholder that shall be furnished to the secretary by the shareholder, (e) sign with the president, or a vice president, certificates for shares of stock of the Corporation, the issuance of which have been authorized by resolution of the board of directors, (f) have general charge of the stock transfer books of the Corporation, and (g) in general perform all duties incident to the office of secretary and other duties as from time to time may be prescribed by the president or the board of directors.

Section 5. Treasurer. The treasurer shall (a) have charge and custody of and be responsible for all funds and securities of the Corporation, (b) receive and give receipts for monies due and payable to the Corporation from any source whatsoever, and deposit monies in the name of the Corporation in the banks, trust companies, or other depositaries as shall be selected by the board of directors, and (c) in general perform all the duties incident to the office of treasurer and other duties as from time to time may be assigned to him by the president or the board of directors. If required by the board of directors, the treasurer shall give a bond for the faithful discharge of his duties in the sum and with the surety or sureties that the board of directors determines.

Section 6. Removal of Officers. An officer or agent elected or appointed by the board of directors or appointed by another officer may be removed by the board whenever in its judgment the removal of the officer or agent will serve the best interests of the Corporation. Any officer or assistant officer, if appointed by another officer, may likewise be removed by such officer. Removal shall be without prejudice to any contract rights of the person removed. The appointment of any person as an officer, agent, or employee of the Corporation does not create any contract rights. The board of directors may fill a vacancy, however occurring, in any office.

An officer may resign at any time by delivering notice to the corporation. A resignation is effective when the notice is delivered unless the notice specifies a later effective date. If a resignation is made effective at a later date, its board of directors may fill the pending vacancy before the effective date if the board of directors provides that the successor does not take office until the effective date. An officer’s resignation does not affect the officer’s contract rights, if any, with the corporation.

Section 7. Salaries. The board of directors from time to time shall fix the compensation of the officers, and no officer shall be prevented from receiving his or her compensation merely because he is also a director of the Corporation.

ARTICLE IV. INDEMNIFICATION

Any person, his or her heirs, or personal representative, made, or threatened to be made, a party to any threatened, pending, or completed action or proceeding, whether civil, criminal, administrative, or investigative, because he or she is or was a director, officer, employee, or agent of the Corporation or serves or served any other corporation or other enterprise in any capacity at the request of the Corporation, shall be indemnified by the Corporation, and the Corporation may advance his or her related expenses to the full extent permitted by Florida law. In discharging his or her duty, any director, officer, employee, or agent, when acting in good faith, may rely upon information, opinions, reports, or statements, including financial statements and other financial data, in each case prepared or presented by (i) more officers or employees of the Corporation whom the director, officer, employee, or agent reasonably believes to be reliable and competent in the matters presented, (ii) counsel, public accountants, or other persons as to matters that the director, officer, employee, or agent believes

to be within that person’s professional or expert competence, or (iii) in the case of the director, a committee of the board of directors upon which the director does not serve, duly designated according to law, as to matters within its designated authority, if the director reasonably believes that the committee is competent. The foregoing right of indemnification or reimbursement shall not be exclusive of other rights to which the person, his or her heirs, or personal representatives may be entitled. The Corporation may, upon the affirmative vote of a majority of its board of directors, purchase insurance for the purpose of indemnifying these persons. The insurance may be for the benefit of all directors, officers, or employees.

ARTICLE V. STOCK CERTIFICATES

Section 1. Issuance. Shares may but need not be represented by certificates.

If certificates are to be issued, the share must first be fully paid.

Section 2. Form. Certificates evidencing shares in this Corporation shall be signed by the president or a vice president and the secretary, assistant secretary or any other officer authorized by the board of directors, and may be sealed with the seal of the Corporation or a facsimile of the seal. Unless the offer and sale of the Corporation’s shares are registered pursuant to every applicable securities law, each certificate shall bear an appropriate legend restricting the transfer of the shares evidenced by that certificate.

Section 3. Lost, Stolen, or Destroyed Certificates. The Corporation may issue a new certificate in the place of any certificate previously issued if the shareholder of record (a) makes proof in affidavit form that the certificate has been lost, destroyed, or wrongfully taken, (b) requests the issue of a new certificate before the Corporation has notice that the certificate has been acquired by the purchaser for value in good faith and without notice of any adverse claim, (c) if requested by the Corporation, gives bond in the form that the Corporation directs, to indemnify the Corporation, the transfer agent, and the registrar against any claim that may be made concerning the alleged loss, destruction, or theft of a certificate, and (d) satisfies any other reasonable requirements imposed by the Corporation.

Section 4. Restrictive Legend. Every certificate evidencing shares that are restricted as to sale, disposition, or other transfer shall bear a legend summarizing the restriction or stating that the Corporation will furnish to any shareholder, upon request and without charge, a full statement of the restriction.

ARTICLE VI. DIVIDENDS

The shareholders from time to time may declare, and the Corporation may pay, dividends on its outstanding shares in the manner and upon the terms and conditions provided by law.

ARTICLE VII. SHAREHOLDERS’ AGREEMENT

In the event of any conflict between the provisions of these bylaws and any shareholders’ agreement entered into by the owners of all of the issued and outstanding shares of the Corporation’s capital stock or their predecessors in ownership, as among the shareholders, the provisions of such shareholders’ agreement shall take precedence. This article may only be amended or repealed by a vote of the shareholders.

ARTICLE VIII. COUNTERPART AND FACSIMILE SIGNATURES
