(a) The Shareholder hereby irrevocably grants to and appoints [David M. Kirk] and [James P. Farley] or either of them in their respective capacities as officers of Merger Subsidiary, with full power of substitution (such individuals and their substitutes each being referred to herein as the “Proxy”), as attorneys and proxies to vote all Subject Shares or to express consent or dissent to corporate action in writing without a meeting, all as the Shareholder is obligated to do pursuant to Section 2 hereof, in the Proxy’s absolute, sole and binding discretion.

Other than as contemplated by Section 2 hereof, with respect to any matter regarding the Merger and each of the other transactions contemplated by the Merger Agreement and this Agreement (and any actions required in furtherance thereof and hereof) or any Alternate Proposal, the Shareholder agrees to refrain from (A) voting at any annual or special meeting of shareholders of Cirronet, (B) executing any written consent in lieu of a meeting of shareholders of Cirronet, (C) exercising any rights of dissent with respect to the Subject Shares, and (D) granting any proxy or authorization to any Person with respect to the voting of the Subject Shares, except pursuant to this Agreement, or taking any action contrary to or in any manner that violates the terms of this Agreement.

(b) The Shareholder hereby represents that any proxies heretofore given in respect of the Subject Shares are not irrevocable, and that any such proxies are hereby revoked.

(c) The Shareholder understands and acknowledges that Parent, Merger Subsidiary and Cirronet have entered into the Merger Agreement in reliance upon the Shareholder’s execution and delivery of this Agreement.

Each Option shall expire if such Option is not exercised prior to the close of business on the 180th day following termination of the Merger Agreement (“Option Expiration Date”).

(b) Parent may exercise any or all of the Options at any time (i) following the earlier of (A) the termination of the Merger Agreement and (B) Cirronet’s first receipt of an Acquisition Proposal following the date hereof and (ii) until the Option Expiration Date. In the event that Parent wishes to exercise an Option, Parent shall give written notice (the date of such notice being herein called the “Notice Date”), to Shareholder specifying a place and date (not later than ten Business Days and not earlier than three Business Days following the Notice Date) for closing such purchase (the “Option Closing”). Parent agrees to exercise all Options granted by Shareholders pro rata according to the number of shares Cirronet Common Stock subject to each Option.

(c) If Parent shall exercise any Option in accordance with the terms of this Agreement, Shareholder shall execute and deliver further transfers, assignments, endorsements, consents and other instruments as Parent may reasonably request for the purpose of effectively carrying out the transactions contemplated by this Agreement and the Merger Agreement, including the transfer of any and all of Shareholder’s Shares Parent and the release of any and all liens, claims and encumbrances covering such Shares, without additional consideration.

(d) At the Option Closing, (i) Parent shall pay the aggregate Purchase Price for the Subject Shares being purchased from each Shareholder by wire transfer in immediately available funds of the total amount of the Purchase Price for such Subject Shares to an account designated by Shareholder by written notice to Parent and (ii) Shareholder shall deliver to Parent a certificate or certificates evidencing the Subject Shares (provided that if any such certificate is lost, then such Shareholder shall deliver a lost certificate affidavit and indemnity in customary form in lieu of such lost certificate), and Shareholder agrees that such Subject Shares shall be transferred free and clear of all liens. All such certificates representing the Subject Shares shall be duly endorsed in blank, or with appropriate stock powers, duly executed in blank, attached thereto, in proper form for transfer, and with all applicable taxes paid or provided for.

(a) Restriction on Transfers. Except as contemplated hereby or by the Merger Agreement and as may otherwise be agreed to by Parent and Merger Subsidiary in writing, the Shareholder shall not (i) transfer (which term shall include, without limitation, any sale, gift,

4

pledge, hypothecation or other disposition), or consent to any transfer of, any or all of the Subject Shares, or any interest therein if such transfer would result in the Shareholder no longer having the power to vote, or cause to be voted, the Subject Shares or (ii) enter into any contract, option or other agreement or understanding with respect to any such transfer of any or all of the Subject Shares, or any interest therein; provided, however, that the Shareholder may (X) transfer Subject Shares to the Shareholder’s family members or a trust for any of their direct or indirect benefit, (Y) transfer Subject Shares in a transaction involving the distribution without consideration of such Subject Shares to the Shareholder’s partners, members or shareholders, or the estate of any of them, and (Z) transfer Subject Shares to any affiliate or subsidiary of the Shareholder; provided, further, that in each such case of (X), (Y) or (Z) above, each Person to which any of the Subject Shares are transferred shall have (v) executed a counterpart of this Agreement and (w) agreed to hold such Subject Shares subject to the terms and provisions of this Agreement to the same extent as the Shareholder.

(b) Restrictions on Proxies and Voting Arrangements. Except as otherwise provided herein, the Shareholder shall not (i) grant any proxy, power-of-attorney or other authorization in or with respect to the Subject Shares or (ii) deposit any of the Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to any of the Subject Shares.

(c) Stop Transfer. The Shareholder shall not request that Cirronet register any transfer (book-entry or otherwise) of any certificate or uncertificated interest representing any of the Shareholder’s Existing Securities, unless such transfer is made in compliance with this Agreement.

(d) Waiver of Appraisal Rights. The Shareholder hereby irrevocably and unconditionally waives, and agrees to prevent the exercise of, any rights of appraisal or rights to dissent in connection with the Merger that the Shareholder may have with respect to the Subject Shares.

(e) No Solicitation. The Shareholder, solely in its capacity as a shareholder of Cirronet, will not and will cause its affiliates, directors, officers, employees, agents and representatives not to, directly or indirectly, (i) solicit, initiate, facilitate or encourage the submission of any Acquisition Proposal, (ii) enter into any agreement, arrangement or understanding with respect to any Acquisition Proposal, or (iii) explore or otherwise participate in any discussions or negotiations regarding, or furnish to any Person (other than Parent and its Representatives) any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or leads to, an Acquisition Proposal. Notwithstanding the foregoing, if Cirronet pursuant to Section 8.1(b) of the Merger Agreement is permitted to furnish information to and engage in discussions and negotiations with a third party, then the Shareholder may also furnish information to, and participate in discussions and negotiations with, such third party to the same extent, but subject to the same limitations, as Cirronet as set forth in the Merger Agreement.

(f) No Inconsistent Arrangements. The Shareholder shall not take any other action that would in any material way restrict, limit or interfere with the performance of any of the Shareholder’s obligations hereunder or the transactions contemplated hereby or by the Merger Agreement.
