These By-Laws are the By-Laws of Entercom Boston 1 Trust, a trust with transferable shares established under the laws of The Commonwealth of Massachusetts (the “Trust”) pursuant to an Agreement and Declaration of Trust (the “Declaration”) made the 18th day of September, 1998.

SECTION 1.1. Meetings. The Annual Meeting of Shareholders shall be held within six (6) months of the end of each fiscal year, commencing with the end of the first full fiscal year. Annual Meetings of Shareholders shall be held at such time, on such day and at such place, as the Trustees may from time to time determine by resolution. Special meetings of Shareholders shall be held in accordance with Section 7.3 of the Declaration and shall be held at such time, on such day and at such place as provided for therein.

SECTION 1.2. Presiding Officer; Secretary. The Chairman of the Trustees, if there is one, and in the absence of the Chairman, if there is one, the President, if there is one, shall preside at each Shareholders’ meeting as chairman of the meeting, or in the absence of the Chairman and the President, the Trustees present at the meeting shall elect one of their number as chairman of the meeting. Unless otherwise provided for by the Trustees, the Secretary of the Trust shall be the secretary of all meetings of Shareholders and shall record the minutes thereof.

SECTION 1.3. Authority of Chairman of Meeting to Interpret Declaration and By-Laws. At any Shareholders’ meeting the chairman of the meeting shall be empowered to determine the construction or interpretation of the Declaration or these By-Laws, or any part thereof or hereof in respect of procedural matters relating to the meeting, and his ruling shall be final.

SECTION 1.4. Voting; Quorum. At each meeting of Shareholders, except as otherwise provided by the Declaration, every holder of record of Shares entitled to vote shall be entitled to a number of votes equal to the number of Shares standing in his name on the Share register of the Trust. Shareholders may vote by proxy and the form of any such proxy may be prescribed from time to time by the Trustees. A quorum shall exist if the holders of a majority of the outstanding Shares of the Trust entitled to vote are present in person or by proxy, but any lesser number shall be sufficient for adjournments. At all meetings of the Shareholders, votes of Shareholders need not be taken by ballot unless otherwise provided for by the Declaration or by vote of the Trustees, but the chairman of the meeting may in his discretion authorize any matter to be voted upon by ballot.

SECTION 1.5. Inspectors. At any meeting of Shareholders, the chairman of the meeting may appoint one or more Inspectors of Election or Balloting to supervise the voting at such meeting or any adjournment thereof. If Inspectors are not so appointed, the chairman of the meeting may, and on the request of any Shareholder present or represented and entitled to vote shall, appoint one or more Inspectors for such purpose. Each Inspector, before entering upon the discharge of his duties, shall take and sign an oath faithfully to execute the duties of Inspector of Election or Balloting, as the case may be, at such meeting with strict impartiality and according to the best of his ability. If appointed, Inspectors shall take charge of the polls and, when the vote is completed, shall make a certificate of the result of the vote taken and of such other facts as may be required by law.

SECTION 1.6. Shareholders’ Action in Writing. Nothing in this Article 1 shall limit the power of the Shareholders to take any action by means of written instruments without a meeting, as permitted by Section 7.7 of the Declaration.

SECTION 1.7. Lost, Stolen, etc., Certificates. If any certificate for certificated Shares shall be lost, stolen, destroyed or mutilated, the Trustees may authorize the issuance of a new certificate of the same tenor and for the same number of Shares in lieu thereof. The Trustees shall require the surrender of any mutilated certificate in respect of which a new certificate is issued, and may, in their discretion, before the issuance of a new certificate, require the owner of a lost, stolen or destroyed certificate, or the owner’s legal representative, to make an affidavit or affirmation setting forth such facts as to the loss, theft or destruction as they deem necessary, and to give the Trust a bond in such reasonable sum as the Trustees direct, in order to indemnify the Trust.
