1. Voting Agreement And Irrevocable Proxy.

Contemporaneously with the execution and delivery hereof, Holder has executed the written consent attached hereto voting in favor of (i) the issuance of shares of First Avenue Common Shares pursuant to the Merger, (ii) the amendment to the certificate of incorporation of First Avenue in the form attached as Exhibit A to the written consent attached hereto, and the amendment to the First

Avenue Networks, Inc. Stock Option Plan in the form attached as Exhibit B to the written consent attached hereto, as contemplated by the Merger Agreement, and the other transactions contemplated by the Merger Agreement. In addition, Holder, solely in Holder’s capacity as a stockholder of First Avenue, hereby agrees that during the period commencing on the date hereof and continuing until the termination of this Agreement (such period, the “Voting Period”), at any meeting (or any adjournment or postponement thereof) of the holders of any class or classes of the capital stock of First Avenue, however called, or in connection with any written consent of the holders of any class or classes of the capital stock of First Avenue, Holder shall vote (or cause to be voted) Holder’s Subject Shares over which Holder then has voting power (or the power to direct the voting) (i) in favor of (A) the issuance of shares of Common Stock as provided in the Merger Agreement, (B) the amendment to the certificate of incorporation of First Avenue in the form attached as Exhibit A to the written consent attached hereto, and (C) the amendment to the First Avenue Networks, Inc. Stock Option Plan in the form attached as Exhibit B to the written consent attached hereto, as contemplated by the Merger Agreement, and each of the other transactions contemplated by the Merger Agreement (and any actions required in furtherance thereof) at every meeting of the stockholders of First Avenue (or in connection with any written consent) at which such matters are considered and at every adjournment thereof, (ii) against any action, proposal, transaction or agreement that would result in a breach in any respect of any covenant, representation or warranty or any other obligation or agreement of First Avenue or any of its Subsidiaries under the Merger Agreement or of Holder under this Agreement, and (iii) except as otherwise agreed to in writing in advance by FiberTower, against the following actions or proposals (other than the transactions contemplated by the Merger Agreement): (A) any extraordinary corporate transaction, such as a merger, consolidation or other business combination involving First Avenue or any of its Subsidiaries and any First Avenue Acquisition Proposal; (B) any sale, lease or transfer of a significant part of the assets (other than sales of current assets in the ordinary course of business) of First Avenue or any of its subsidiaries, or a reorganization, recapitalization, dissolution or liquidation of First Avenue or any of its subsidiaries (each of the actions in clauses (A) or (B), a “Business Combination”); (C) any change in the persons who constitute the board of directors of First Avenue that is not approved in advance by at least a majority of the persons who were directors of First Avenue as of the date of this Agreement (or their successors who were so approved); (D) any change in the present capitalization of First Avenue or any amendment of First Avenue’s certificate of incorporation or bylaws not otherwise permitted under the Merger Agreement; (E) any other material change in First Avenue’s corporate structure or business; or (F) any other action or proposal involving First Avenue or any of its subsidiaries that is intended, or could reasonably be expected, to prevent, impede, interfere with, delay, postpone, or adversely affect the transactions contemplated by the Merger Agreement. Any such vote shall be cast or consent shall be given in accordance with such procedures relating thereto as shall ensure that it is duly counted for purposes of determining that a quorum is present and for purposes of recording the results of such vote or consent. Holder agrees not to enter into any agreement, letter of intent, agreement in principle or understanding with any person that violates or conflicts with or could reasonably be expected to violate or conflict with the provisions and agreements contained in this Agreement or the Merger Agreement.
