1.1 Place of Meeting. Every meeting of the stockholders (the “Stockholders”) of Community Bank System, Inc. (the “Corporation”) shall be held at the office of the Corporation or at such other place within or without the State of Delaware or solely by means of remote communication pursuant to Section 211(a)(2) of the Delaware General Corporation Law (the “General Corporation Law”), as shall be specified or fixed in the notice of such meeting or in the waiver or notice thereof.

1.2 Annual Meeting. A meeting of Stockholders shall be held annually for the election of Directors and the transaction of other business at such hour and on such day as may be determined by the Board of Directors (the “Board”) and designated in the notice of meeting.

1.3 Business at Annual Meeting. At an annual meeting of Stockholders, only such business or proposals (“Business”) shall be conducted as shall have been properly brought before an annual meeting. To be properly brought before an annual meeting, the Business must be: (a) specified in the notice of annual meeting (or any supplement thereto) given by or at the direction of the Board; (b) otherwise properly brought before an annual meeting by or at the direction of the Board; or (c) otherwise properly brought before an annual meeting in accordance with this Section of the Bylaws.

For Business to be properly brought before an annual meeting by a Stockholder, the Stockholder must give timely written notice of the Business to be brought before an annual meeting to the Secretary of the Corporation. To be timely, a Stockholder’s written notice must be delivered or mailed to and actually received at the Company’s principal headquarters at least 45 days prior to the date of the annual meeting, provided, however, that if less than 60 days notice of the annual meeting is given, then the Stockholder’s written notice of the Business to be brought before the annual meeting must be so received not later than the close of business on the 15^th day following the date on which such notice of the date of annual meeting was mailed. A Stockholder’s written notice to the Secretary of the Corporation of the Business to be brought before the annual meeting shall set forth as to each matter: (a) a brief description of the Business desired to be brought before the annual meeting; (b) name and address of the Stockholder proposing the Business to be brought before the annual meeting; (c) the class and number of shares of the Corporation held by the Stockholder proposing to bring Business before an annual meeting; (d) any material interest of the Stockholder making the written submission in the Business to be brought before the annual meeting; and (3) the same information required by clauses (b), (c), and (d) above with respect to any other Stockholder that, to the knowledge of the Stockholder proposing such Business, supports such proposal.

Notwithstanding anything in the Corporation’s Bylaws to the contrary, no Business shall be conducted at an annual meeting except in accordance with the provisions and procedures set forth in this Section of the Corporation’s Bylaws.

The presiding officer of an annual meeting shall, if the facts warrant, determine and declare to the annual meeting that the Business was not properly brought before the meeting, and, in accordance with the provisions of this Section of the Corporation’s Bylaws, the presiding officer of the meeting shall so declare to the annual meeting, and any such Business not properly brought before the meeting shall not be transacted.

1.4 Other Special Meetings. A special meeting of Stockholders unless otherwise prescribed by statute, may be called at any time by the Board or by the Chair of the Board or by the Executive Committee of the Board. At any special meeting of Stockholders, only such Business may be transacted as is related to the purpose or purposes of such meeting set forth in the notice thereof given pursuant to Section 1.6 of the Bylaws or in any waiver of notice thereof given pursuant to Section 1.7 of the Bylaws.

1.5 Fixing Record Date. For the purpose of determining the Stockholders entitled to notice of or to vote at any meeting of Stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, or for the purpose of determining Stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled 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 may fix, in advance, a date as the record date for any such determination of Stockholders. Such date shall not be more than sixty nor less than ten days before the date of such meeting, nor more than sixty days prior to any other action. If no such record date is fixed:

1.5.1 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;

1.5.2 The record date for determining Stockholders for any purpose other than those specified in Section 1.5.1 shall be at the close of business on the day on which the Board adopts the resolution relating thereto. When a determination of Stockholders entitled to notice of or to vote at any meeting of Stockholders has been made as provided in this Section 1.5, such determination shall apply to any adjournment thereof, unless the Board fixes a new record date for the adjourned meeting.

1.6 Notice of Meetings of Stockholders. Except as otherwise provided in Sections 1.5 and 1.7 of the Bylaws, whenever under the General Corporation Law or the Certificate of Incorporation or the Bylaws, Stockholders are required or permitted to take any action at a meeting, written notice shall be given stating the place, date and hour of the meeting, the means of remote communications, if any, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. A copy of the notice of any meeting shall be given, personally or by mail, not less than ten nor more than sixty days before the date of the meeting, to each Stockholder entitled to notice of or to vote at such meeting. If mailed, such notice shall be deemed to be given when deposited in the United States mail, with postage prepaid, directed to the Stockholder at his or her address as it appears on the records of the Corporation. In addition, if given by electronic mail, then such notice by electronic mail shall be deemed to be given when directed to such Stockholder’s electronic mail address (unless such Stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notices by electronic mail or such notice is prohibited by the General Corporation Law to be given by electronic means). If such notice is transmitted by any other form of electronic transmission, such notice shall be deemed to be given when directed to the Stockholder. An affidavit of the Secretary or and Assistant Secretary or of the transfer agent of the Corporation that the notice required by this section has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken, and at the adjourned meeting any business may be transacted that might have been transacted at the meeting as originally called. If, however, the adjournment is for more than thirty days, or if after the 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.

1.7 Waivers of Notice. Notice of meeting need not be given to any Stockholder who submits a signed waiver of notice, in person or by proxy, or a waiver by electronic transmission, whether before or after the meeting. The attendance of any Stockholder at a meeting, in person or by proxy, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any Business because the meeting is not lawfully called or convened, shall constitute a waiver of notice by such Stockholder.

1.8 List of Stockholders. The Secretary shall prepare and make, or caused to be prepared and made, at least ten 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. Nothing in this Section shall require the Corporation to include electronic mail addresses or other electronic content information on such list. 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 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 shall also 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. If the meeting is to be held solely by means of remote communication, then such list shall also be open to the examination of any Stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation.

1.9 Quorum of Stockholders; Adjournment. The holders of one-third or more of the shares of stock entitled to vote at any meeting of Stockholders, present in person or represented by proxy, shall constitute a quorum for the transaction of any business at such meeting. When a quorum is once present to organize a meeting of the Stockholders, it is not broken by the subsequent withdrawal of any Stockholders and a quorum shall be deemed to exist for the remainder of the meeting and for any adjournment of that meeting unless a new record date is or must be set for the adjourned meeting. The holders of a majority of the shares of stock present in person or represented by proxy at any meeting of Stockholders, including an adjourned meeting, whether or not a quorum continues to be present, may adjourn such meeting to another time and place. At an adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the original meeting. If the adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each Stockholder entitled to vote at the meeting.

1.10 Voting; Proxies. Unless otherwise provided in the Certificate of Incorporation, every Stockholder of record shall be entitled at every meeting of Stockholders to one vote for each share of capital stock standing in his or her name on the record of Stockholders determined in accordance with Section 1.8 of the Bylaws. If the Certificate of Incorporation provides for more or less than one vote for any share, on any matter, every reference in the Bylaws or the General Corporation Law to a majority or other proportion of stock shall refer to such majority or other proportion of the votes of such stock.

The provisions of Sections 212 and 217 of the General Corporation Law shall apply in determining whether any shares of capital stock may be voted and the person, if any, entitled to vote such shares; but the Corporation shall be protected in treating the persons in whose names shares of capital stock stand on the record of Stockholders as owners thereof for all purposes. At any meeting of Stockholders (at which a quorum was present to organize the meeting), all matters, except as otherwise provided by law or by Certificate of Incorporation or by the Bylaws, shall be decided by a majority of the votes cast at such meeting by the holders of shares present in person or represented by proxy and entitled to vote thereon, whether or not a quorum is present when the vote is taken. All elections of Directors shall be written ballot unless otherwise provided in the Certificate of Incorporation or, if authorized by the Board, such requirement for a written ballot may be satisfied by a ballot submitted by electronic submission provided that such electronic submission meets the requirements of Section 211(e) of the General Corporate Law. In voting on any other question on which a vote by ballot is required by law or is demanded by any Stockholder entitled to vote, the voting shall be by ballot. Each ballot shall be signed by the Stockholders voting or by his or her proxy, and shall state the number of shares voted. On all other questions, the voting may be viva voce. Every Stockholder entitled to vote at a meeting of Stockholders may authorize another person or persons to act for him or her by proxy. The validity and enforceability of any proxy shall be determined in accordance with Section 212 of the General Corporation Law.

1.11 Selection and Duties of Inspectors at Meetings of Stockholders. The Board, in advance of any meeting of Stockholders, may appoint one or more inspectors to act at the meeting or any adjournment thereof. If inspectors are not so appointed, the person presiding at such meeting may, and on the request of any Stockholder entitled to vote thereat shall, appoint one or more inspectors.

In case any person appointed fails to appear or act, the vacancy may be filled by appointment made by the Board in advance of the meeting or at the meeting by the person presiding thereat. 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 at such meeting with strict impartiality and according to the best of his or her ability. The inspector of inspectors shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the validity and effect of proxies, and shall receive votes, ballots or consents, hear and determine all challenges and questions arising in connection with the right to vote, count and tabulate all votes, ballots or consents, determine the result, and do such acts as are proper to conduct the election or vote with fairness to all Stockholders. On request of the person presiding at the meeting or any Stockholder entitled to vote thereat, the inspector or inspectors shall make a report in writing of any challenge, question or matter determined by him, her, or them and execute a certificate of any fact found by him, her or them. Any report or certificate made by the inspector or inspectors shall be prima facie evidence of the facts stated and of the vote as certified by him or them.

1.12 Organization. At every meeting of Stockholders, the Chair, or in the absence of the Chair, the Vice Chair, or in the absence of the Vice Chair, the President, or in the absence of the President, a Vice President, and in case more than one Vice President shall be present, that Vice President designated by the Board (or in the absence of any such designation, the most senior Vice President, based on age, present), shall act as chair of the meeting. The Secretary, or in his or her absence one of the Assistant Secretaries, shall act as secretary of the meeting.

In case none of the officers above designated to act as chair or secretary of the meeting, respectively, shall be present, a chair or a secretary of the meeting, as the case may be, shall be chosen by a majority of the votes cast at such meeting by the holders of shares of capital stock present in person or represented by proxy and entitled to vote at the meeting.

1.13 Order of Business. The order of business at all meetings of Stockholders shall be as determined by the chair of the meeting, but the order of business to be followed at any meeting at which a quorum is present may be changed by a majority of the votes cast at such meeting by the holders of shares of capital stock present in person or represented by proxy and entitled to vote at the meeting.

1.14 Postponement of Meeting. Any annual meeting of Stockholders or any special meeting of Stockholders called by the Chair, the Board, or the Executive Committee of the Board, may be postponed at any time or from time to time after written notice of the meeting has been delivered to Stockholders by action of the Board or a duly authorized committee thereof. Any such postponement or postponements shall be disclosed in any public filing with the Securities and Exchange Commission or by means of a press release to Dow Jones & Company, Associated Press, or any similar service promptly following such postponement, and promptly thereafter written notice of such postponement stating the place, day, and hour to which the meeting was postponed shall be delivered to each Stockholder of record entitled to vote at such meeting.

2.1 General Powers. Except as otherwise provided in the Certificate of Incorporation, the business and affairs of the Corporation shall be managed by or under the direction of the Board. The Board may adopt such rules and regulations, not inconsistent with the Certificate of Incorporation or the Bylaws or applicable laws, as it may deem proper for the conduct of its meetings and the management of the Corporation. In addition to the powers expressly conferred by the Bylaws, the Board may exercise all powers and perform all acts which are not required, by the Bylaws or the Certificate of Incorporation or by law, to be exercised and performed by the Stockholders.

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 transaction of any 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 Directors, or members of a committee of Directors, need be specified in any written waiver of notice.

The Board shall establish an audit committee, a compensation committee, a nominating and corporate governance committee (“Governance Committee”), and an executive committee. The same rules that govern meetings and voting requirements of the Board shall apply to the conduct of committee meetings, and a majority of the appointed committee members shall represent a quorum. The functions and responsibilities of such committees shall be determined by the Board from time to time and reflected in committee charters for standing committees or authorizing resolutions of the Board.

The President may, with the Chair of the Board, any Vice President, the Secretary or the Treasurer or an Assistant Secretary or an Assistant Treasurer, sign certificates for shares of capital stock of the Corporation. The President may sign and execute in the name of the Corporation deeds, mortgages, bonds, contracts and other instruments, except in cases where the signing and execution thereof shall be expressly delegated by the Board or by the Bylaws to some other officer or agent of the Corporation, or shall be required by law otherwise to be signed or executed; and, in general, he or she shall perform all duties incident to the office of President and such other duties as from time to time may be assigned to him or her by the Board.
