MEETINGS OF SHAREHOLDERS

Section 1. Place of Meetings. All annual meetings of the shareholders and all special meetings of the shareholders called by the president or the board of directors shall be held at such place within or without the State of Rhode Island as shall be stated in the notice of meeting. All other special meetings of the shareholders shall be held at an office of the Corporation in the State of Rhode Island.

Section 2. Annual Meetings. An annual meeting of the shareholders shall be held on the fourth Thursday in June of each year if not a legal holiday in the place where it is to be held, and if a legal holiday, then on the next day following which is not a legal holiday, beginning at 10:00 A.M. At each annual meeting, the shareholders shall elect a board of directors and shall transact such other business as may properly come before the meeting. In the event of the failure to hold said annual meeting at any time or for any cause, any and all business which might have been transacted at such meeting may be transacted at the next succeeding meeting, whether special or annual.

Section 3. Special Meetings. A special meeting of the shareholders, for any purpose or purposes, may be called by the president, the board of directors, or the holders of record of not less than one-tenth of the shares entitled to vote at such meeting. Any such call shall state the purpose or purposes of the proposed meeting.

Section 4. Notice of Meetings. Written notice of each annual or special meeting stating the place, day and hour of the meeting (and the purpose or purposes of any special meeting) shall be given by or at the direction of the president, the secretary, or the person or persons calling the meeting to each shareholder of record entitled to vote at such meeting not less than ten nor more than sixty days before the meeting. Business transacted at any special meeting of shareholders shall be limited to the purposes stated in the notice of the meeting or any written waiver thereof.

Section 5. Quorum. The holders of a majority of the capital shares issued, outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at all meetings of the shareholders for the transaction of business. If, however, such quorum shall not be present or represented at any meeting of the shareholders, the shareholders entitled to vote thereat, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present or represented. At such adjourned meeting at which a quorum shall be present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. If adjournment is for more than thirty days, a notice of the adjourned meeting shall be given to each shareholder entitled to vote at the meeting. When a quorum is present at any meeting, the vote of the holders of a majority of the capital

shares entitled to vote and present in person or represented by proxy, shall decide any question brought before such meeting, unless the vote of a greater number is required by law.

Section 6. Proxies. Every shareholder entitled to vote at a meeting or to express consent without a meeting may authorize another person or persons to act for him by proxy, executed in writing by the shareholder or by his duly authorized attorney-in-fact. No proxy shall be valid after eleven months from the date thereof, unless otherwise provided in the proxy.

Section 7. Consent Votes. Any action required or permitted to be taken at a meeting of shareholders may be taken without a meeting if all the shareholders entitled to vote thereon consent thereto in writing. In addition to the foregoing, except as otherwise provided by the Rhode Island Business Corporation Act (the “Act”), any action required or permitted to be taken at a meeting of the shareholders by the Act, the articles of incorporation or these by-laws, may be taken without a meeting upon the written consent of less than all the shareholders entitled to vote thereon if the shareholders who so consent would be entitled to cast at least the minimum number of votes which would be required to take such action at a meeting at which all shareholders entitled to vote thereon are present. Prompt notice of such action shall be given to all shareholders who would have been entitled to vote upon the action if such meeting were held.

At all meetings of the board of directors, a majority of the number of directors fixed pursuant to Section 2 of this Article shall constitute a quorum for the transaction of business, and the act of a majority of the directors present at a meeting at which a quorum is present shall be the act of the board of directors, unless the act of a greater number is required by the Act or by the articles of incorporation.

Section 7. Directors’ Consent Vote. Any action required or permitted to be taken at a meeting of the board of directors or of any committee thereof may be taken without a meeting if a consent in writing, setting forth the action so to be taken, shall be signed before or after such action by all of the directors, or all of the members of such committee, as the case may be.

Section 8. Committees of Directors. The board of directors may, by vote passed by a majority of the whole board, designate one or more committees, including an executive committee, each committee to consist of two or more of the directors of the Corporation. The board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Except as provided by the Act, any such committee, to the extent provided in the resolution, shall have and may exercise all the authority of the board of directors in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers

5

which may require it; provided, however, that in the absence or disqualification of any member of such committee or committees, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the board of directors to act at the meeting in the place of any such absent or disqualified member. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the board of directors. Each committee shall keep regular minutes of its proceedings and report the same to the board of directors when required.

Members of special or standing committees may be allowed like compensation for attending committee meetings.

INDEMNIFICATION

Section 1. Definitions. As used herein, the following terms will have the following respective meanings:

“Covered Act” means any act or omission of an Indemnified Person in the Indemnified Person’s official capacity with the Corporation and while serving as such or while serving at the request of the Corporation as a member of the governing body, officer, employee or agent of another corporation, including, but not limited to corporations which are subsidiaries or affiliates of the Corporation, partnership, joint venture, trust, other enterprise or employee benefit plan.

“Excluded Claim” has the meaning set forth in Section 4, hereof.

10

“Expenses” means any reasonable expenses incurred by the Indemnified Person in connection with the defense of any claim made against the Indemnified Person for Covered Acts including, without being limited to, legal, accounting or investigative fees and expenses, including the expense of bonds necessary to pursue an appeal of an adverse judgment.

“Indemnified Person” means any director or officer of the Corporation.

“Loss” means any amount which the Indemnified Person is legally obligated to pay as a result of any claim made against the Indemnified Person for Covered Acts including, without being limited to, judgments for, and awards of, damages, amounts paid in settlement of any claim, any fine or penalty or, with respect to an employee benefit plan, any excise tax or penalty.

“Proceeding” means any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative.

Section 2. Indemnification. Subject to the exclusions hereinafter set forth, by adoption of this Article the Corporation agrees that it will indemnify the Indemnified Person against and hold the Indemnified Person harmless from any Loss or Expenses.

Section 3. Advance Payment of Expenses. By the adoption of this Article, the Corporation agrees that it will pay the Expenses of the Indemnified Person in advance of the final disposition of any Proceeding except to the extent that the defense of a claim against the Indemnified Person is undertaken pursuant to any directors’ and officers’ liability insurance maintained by the Corporation. The advance payment of Expenses will be subject to the Indemnified Person’s first agreeing in writing with the Corporation to repay the sums paid by it

11

hereunder if it is thereafter determined that the Proceeding involved an Excluded Claim or that the Indemnified Person was otherwise not entitled to indemnity under this Article.

Section 4. Exclusions. The Corporation will not be liable to pay any Loss or Expenses (an “Excluded Claim”):

(a) For which payment is actually made to or on behalf of the Indemnified Person under such directors’ and officers’ liability insurance policy as may be maintained by the Corporation (except for any excess beyond the amount covered by such insurance);

(b) For which the Indemnified Person is otherwise indemnified or reimbursed;

(c) With respect to a Proceeding in which a final judgment or other final adjudication determines that the Indemnified Person is liable to the Corporation for: (i) a breach of the Indemnified Person’s duty of loyalty to the Corporation or its shareholders; (ii) acts or omissions not in good faith or which involve intentional misconduct or knowing violation of law; (iii) liability imposed pursuant to the provisions of Section 7-1.1-43 of the Act; or (iv) any transaction (other than a transaction approved in accordance with Section 7-1.1-37.1 of the Act) from which the Indemnified Person derived an improper personal benefit;

(d) For an accounting of profits in fact made from the purchase or sale by the Indemnified Person of securities of the Corporation within the meaning of Section 16 of the Securities Exchange Act of 1934 as amended; or

(e) If a final judgment or other final adjudication determines that such payment is unlawful.

Section 5. Notice to Corporation; Insurance. Promptly after receipt by the Indemnified Person of notice of the commencement of or the threat of commencement of any Proceeding, the Indemnified Person will, if indemnification with respect thereto may be sought

12

from the Corporation under these Articles, notify the Corporation of the commencement thereof. If, at the time of the receipt of such notice, the Corporation has any directors’ and officers’ liability insurance in effect, the Corporation will give prompt notice of the commencement of such Proceeding to the insurer in accordance with the procedures set forth in the policy or policies in favor of the Indemnified Person. The Corporation will thereafter take all necessary or desirable action to cause such insurer to pay, on behalf of the Indemnified Person, all Loss and Expenses payable as a result of such Proceeding in accordance with the terms of such policies.

Section 6. Indemnification Procedures. (a) Payments on account of the Corporation’s indemnity against Loss will be subject to the Corporation’s first determining that the Loss results from a claim which is not an Excluded Claim. Such a determination will be made:

(i) By the board of directors by a majority vote of a quorum consisting of directors not at the time parties to the Proceeding; or

(ii) If a quorum cannot be obtained for purposes of clause (i) of this subparagraph (a), then by a majority vote of a committee of the Board duly designated to act in the matter by a majority vote of the full Board (in which designation directors who are parties to the Proceeding may participate) consisting solely of two or more directors not at the time parties to the Proceeding; or

(iii) By independent legal counsel designated: (A) by the board of directors in the manner described in clause (i) of this subparagraph (a), or by a committee of the Board established in the manner described in clause (ii) of this subparagraph (a), or (B) if the requisite quorum of the full Board cannot be obtained therefor and a committee cannot be so established, by a majority vote of the full Board (in which designation directors who are parties to the Proceeding may participate); or

13

(iv) By the shareholders.

The determination required by this subparagraph (a) will be made within 60 days of the Indemnified Person’s written request for payment of a Loss, and if it is determined that the Loss is not an Excluded Claim payment will be made forthwith thereafter.

(b) Payment of an Indemnified Person’s Expenses in advance of the final disposition of any Proceeding will be made within 20 days of the Indemnified Person’s written request therefor. From time to time prior to the payment of Expenses the Corporation may, but is not required to, determine (in accordance with subparagraph (a), above) whether the Expenses claimed may reasonably be expected, upon final disposition of the Proceeding, to constitute an Excluded Claim. If such a determination is pending, payment of the Indemnified Person’s Expenses may be delayed up to 60 days after the Indemnified Person’s written request therefor, and if it is determined that the Expenses are not an Excluded Claim, payment will be made forthwith thereafter.

Section 7. Settlement. The Corporation will have no obligation to indemnify the Indemnified Person under these Articles for any amounts paid in settlement of any Proceeding effected without the Corporation’s prior written consent. The Corporation will not unreasonably withhold or delay its consent to any proposed settlement. The Corporation may consent to a settlement subject to the requirement that a determination thereafter will be made as to whether the Proceeding involved an Excluded Claim or not.

Section 8. Rights Not Exclusive. The rights provided hereunder will not be deemed exclusive of any other rights to which the Indemnified Person may be entitled under the Act, any by-law, agreement, vote of shareholders or of disinterested directors or otherwise, both as to action in the Indemnified Person’s official capacity and as to action in any other capacity while

14

holding such office, and shall continue after the Indemnified Person ceases to serve the Corporation in an official capacity.

Section 9. Enforcement. (a) The Indemnified Person’s right to indemnification hereunder will be enforceable by the Indemnified Person in any court of competent jurisdiction and will be enforceable notwithstanding that an adverse determination has been made as provided in Section 6 hereof.

(b) In the event that any action is instituted by the Indemnified Person under these Articles to enforce or interpret any of the terms of these Articles, the Indemnified Person will be entitled to be paid all court costs and expenses, including reasonable attorneys’ fees, incurred by the Indemnified Person with respect to such action, unless the court determines that each of the material assertions made by the Indemnified Person as a basis for such action was not made in good faith or was frivolous.

Section 10. Severability. If any provision of this Article is determined by a court to require the Corporation to perform or to fail to perform an act which is in violation of applicable law, this Article shall be limited or modified in its application to the minimum extent necessary to avoid a violation of law, and, as so limited or modified, this Article shall be enforceable in accordance with its terms.

Section 11. Successor and Assigns. This Article will be (a) binding upon all successors and assigns of the Corporation (including any transferee of all or substantially all of its assets) and (b) binding on and inure to the benefit of the heirs, executors, administrators, and other personal representatives of the Indemnified Person. If the Corporation sells or otherwise transfers all or substantially all of its assets to a third party, the Corporation will, as a condition

15

of such sale or other transfer, require such third party to assume and perform the obligations of the Corporation under this Article.

Section 12. Amendment. No amendment of this Article will be effective as to an Indemnified Person without his or her written consent.
