(b) CTI Subject Shares. Stockholder is the record and beneficial owner of, and has good and marketable title to, 14,214,857 shares of CTI Common Stock, free and clear of any encumbrances, agreements, adverse claims, liens or other arrangements with respect to the ownership of or the right to vote or dispose of such shares of CTI Common Stock.

At any meeting of stockholders of CTI or at any adjournment thereof or in any other circumstances upon which Stockholder's vote, consent or other approval (including by written consent) is sought, Stockholder shall vote all of the CTI Subject Shares then beneficially owned by Stockholder (i) in favor of the Transaction and the adoption and approval of the Merger Agreement and each of the other transactions contemplated by the Merger Agreement and (ii) against any action or agreement that would result in a material breach of any covenant, representation or warranty or any other obligation or agreement of CTI under the Merger Agreement. Stockholder shall not hereafter, unless and until this Agreement terminates pursuant to Section 4 hereof, purport to grant any proxy or power of attorney with respect to any of the CTI Subject Shares, deposit any of the CTI Subject Shares into a voting trust or enter into any agreement (other than this Agreement), arrangement or understanding with any person, directly or indirectly, to vote, grant any proxy or give instructions with respect to the voting of any of the CTI Subject Shares. Stockholder further agrees not to commit or agree to take any action inconsistent with the foregoing. (b) Pre-Closing Transfer Restrictions. Except as contemplated by this Agreement or the Merger Agreement, Stockholder agrees not to (i) sell, hypothecate, transfer, pledge, encumber, assign or otherwise dispose of (including by gift) 2 3 (collectively, "Transfer"), or enter into any contract, option, put, call or other arrangement or understanding (including any profit sharing arrangement) with respect to the Transfer of, any of the CTI Subject Shares to any person, (ii) trade or take any position, hedge or otherwise, with respect to the CTI Subject Shares, (iii) enter into any voting arrangement or understanding, whether by proxy, voting agreement or otherwise, with respect to any of the CTI Subject Shares or (iv) take any action that would make any of its representations or warranties contained herein untrue or incorrect to a material extent or have the effect of preventing or materially impeding Stockholder from performing any of its obligations under this Agreement. Notwithstanding the foregoing, Stockholder may Transfer any of the CTI Subject Shares to any person who (x) is, at the time of such Transfer, already subject to an agreement with WAXS substantially identical in form and substance hereto (in which case, the CTI Subject Shares subject to the Transfer shall be governed by such substantially identical agreement) or (y) delivers to WAXS a counterpart of this Agreement duly executed by such person and otherwise agrees to be bound by all the terms and conditions hereof, and WAXS is otherwise reasonably satisfied that this Agreement is fully enforceable against such person; provided, however, that Stockholder shall not be entitled to Transfer any of the CTI Subject Shares unless immediately following such Transfer, the aggregate number of CTI Subject Shares subject to the terms and conditions hereof and/or to the terms and conditions of a substantially identical agreement or agreements with WAXS shall be at least equal to the aggregate number of CTI Subject Shares which are subject to the terms and conditions of this Agreement as of the date of the Merger Agreement. (c) Post-Closing Transfer Restrictions. Until six (6) months following the Effective Time, Stockholder agrees not to (i) Transfer or enter into any contract, option, put, call or other arrangement or understanding (including any profit sharing arrangement) with respect to the Transfer of any of the shares of WAXS Common Stock issued to Stockholder pursuant to the Merger Agreement to any person, or (ii) trade or take any position, hedge or otherwise, with respect to the shares of WAXS Common Stock issued to Stockholder pursuant to the Merger Agreement. Notwithstanding the foregoing, Stockholder shall be entitled to enter into one or more Qualifying Transactions (as defined below). If, on or prior to fifteen (15) days following the Effective Time (the "Sale Deadline"), (i) Stockholder shall have complied with its covenants set forth below in this Section 2(c), and (ii) Stockholder shall not have sold shares of WAXS Common Stock acquired by Stockholder pursuant to the Merger Agreement to a third party or third parties unrelated to WAXS (within the meaning of Treas. Reg. Sec. 1.368 3(e)(3)) for a per share price equal to at least the Resale Price (as defined below), in one or more transactions (each, a "Qualifying Transaction"), and (iii) the aggregate Gross Cash Proceeds (as defined below) to Stockholder of all such Qualifying Transactions are less than $30,000,000, then Stockholder shall have the right to sell, subject to compliance with the provisions below in this Section 2(c), WAXS Common Stock which yields Gross Cash Proceeds equal to not more than the Unsold Amount (as defined below). Stockholder shall give WAXS written notice promptly after the consummation of any Qualifying Transaction. Stockholder shall be obligated to accept any bona fide offer for, and use commercially reasonable efforts to consummate on or prior to the Sale Deadline, one or more Qualifying Transactions which provide for a per share price at least equal to 3 4 the Resale Price resulting in aggregate Gross Cash Proceeds to Stockholder of up to $30,000,000. If Stockholder shall be entitled to sell shares of WAXS Common Stock in respect of any Unsold Amount pursuant to this Section 2(c), Stockholder shall give written notice to WAXS so stating (and stating the number of shares of WAXS Common Stock that Stockholder is so entitled to sell) not less than five days prior to any such permitted sale of shares of WAXS Common Stock. As used herein, (i) the "Resale Price" equals (x) the market price of WAXS Common Stock as of the time a written commitment to purchase shares of WAXS Common Stock has been received by Stockholder (the "Commitment Price") or (y) a variable price equal to the market price of WAXS Common Stock at the time of the closing of the applicable Qualifying Transaction, provided that such price is between fifteen percent (15%) below or fifteen percent (15%) above the Commitment Price; (ii) the "Unsold Amount" means the difference between $30,000,000 and the Gross Cash Proceeds to Stockholder of all Qualifying Transactions competed prior to the Sale Deadline; and (iii) "Gross Cash Proceeds" means the gross cash proceeds to Stockholder from the consummation of any Qualifying Transaction hereunder, net of reasonable and customary expenses incurred by Stockholder in connection with such transaction (but not net of any taxes incurred by Stockholder in connection with any such Qualifying Transaction). 3. No Ownership Interest. Except as set forth in Section 2, nothing contained in this Agreement shall be deemed to vest in anyone other than Stockholder any direct or indirect ownership or incidents of ownership of or with respect to any of the CTI Subject Shares. All rights, ownership and economic benefits of and relating to the CTI Subject Shares shall remain and belong to Stockholder, and no one shall have any authority to manage, direct, restrict, regulate, govern, or administer any of the policies or operations of CTI or exercise any power or authority to direct the voting of any of the CTI Subject Shares as a result of this Agreement, except to the extent set forth in Section 2(a). 4.
