ARTICLE 3. TRANSFER OF SHARES 3.1. RESTRICTIONS ON TRANSFER. So long as this Agreement is in effect, no Stockholder shall sell, assign, transfer, give, encumber, pledge, hypothecate or in any other way dispose of any Shares or any Convertible Securities (any of which being a "TRANSFER"), except as provided in this Agreement. No Transfer in violation of this Agreement shall be made or recorded on the books of the Company and any such Transfer shall be void and of no force or effect. Subject to the terms of this Agreement, the Stockholders shall be entitled to exercise all rights of ownership of their Shares and Convertible Securities. 3.2. CERTAIN PERMITTED TRANSFERS. The Company and the Stockholders acknowledge and agree that any of the following Transfers shall be deemed to be in compliance with this Agreement, and shall not be governed by Section 3.3 or 3.4: (a) a Transfer made to the Company pursuant to Article 3 hereof or the redemption provisions applicable to the Preferred Stock as in effect from time to time; (b) a Transfer upon the death of a Stockholder to his executors, administrators and testamentary trustees; (c) a Transfer made by Sarnoff or Wave to any of their respective Affiliates or to any of their respective officers, directors, employees or consultants, or to any officer, director, employee or consultant of any of their respective Affiliates; and (d) a Transfer made for nominal consideration or as a gift in compliance with applicable federal and state securities laws to the Stockholder's spouse, parents or issue or to a trust, the beneficiaries of which, or to a corporation or partnership the stockholders or partners of which, include only the Stockholder and such Stockholder's spouse or issue. 3.3. RIGHTS OF FIRST REFUSAL AND FIRST OFFER. (a) Each Stockholder agrees that, subject to the restrictions on Transfers contained in Sections 3.4 and 3.5 hereof and subject to the -7- provisions of Section 3.3(g), if any Stockholder (for purposes of this Section 3.3, a "TRANSFERRING STOCKHOLDER") wishes to Transfer any or all of the Shares or Convertible Securities then owned by such Transferring Stockholder, other than as provided in Section 3.2, 3.5 or 3.6 hereof, then such Transferring Stockholder shall first give a written notice (the "TRANSFER NOTICE") to the Company (and to the other Founder if the Transferring Stockholder is a Founder) specifying the number of Shares or Convertible Securities such Transferring Stockholder wishes to Transfer (the "TRANSFER SECURITIES"), containing an irrevocable offer (open to acceptance for a period of 30 days after the date such Transfer Notice is received) to sell the Transfer Securities to the Company (and the other Founder, if applicable) at the price (and upon such other terms) stated in the Transfer Notice, which price and terms shall be the same as the price and terms offered to such Stockholder by a bona fide third party offeror whose identity has been disclosed by the Transferring Stockholder (the "TRANSFER PRICE"). (b) The Company shall have the right to purchase all, but not less than all, of the Transfer Securities at the Transfer Price and on terms identical to those set forth in the Transfer Notice. The Company shall have 20 days following receipt of the Transfer Notice (the "COMPANY PERIOD") to deliver written notice to the Transferring Stockholder that it wishes to purchase the Transfer Securities ("COMPANY ACCEPTANCE NOTICE"). If the Company shall not give a Company Acceptance Notice within the Company Period, the Company shall be deemed not to have elected to purchase the Transfer Securities. (c) If the Company has not elected (or has been deemed not to have elected) to purchase the Transferring Securities within the Company Period and the Transferring Stockholder is a Founder, the other Founder shall have the right to purchase all, but not less than all, of the Transfer Securities. Such other Founder shall have 20 days following the end of the Company Period to deliver a written notice to the Transferring Stockholder that it wishes to purchase the Transfer Securities ("FOUNDER ACCEPTANCE NOTICE"). If such Founder shall not give a Founder Acceptance Notice within 20 days following the end of the Company Period, such Founder shall be deemed not to have elected to purchase the Transfer Securities. (d) The closing of the purchase and sale of the Transfer Securities pursuant to clauses (b) or (c) of this Section 3.3 shall take place at the principal offices of the Company on the 15th business day after the Company Acceptance Notice or Founder Acceptance Notice, as applicable, is given. At such closing, the Company or the Founder, as applicable, shall deliver a certified check in the appropriate amount to the Transferring -8- Stockholder against delivery of duly endorsed certificates representing the Transfer Securities to be purchased. The Transfer Securities shall be delivered free and clear of all Encumbrances other than those imposed by this Agreement. (e) If the Company and, if applicable, the Founders, have not elected (or have been deemed not to have elected) to purchase the Transfer Securities pursuant to this Section 3.3, then the Transferring Stockholder shall have 90 days in which to Transfer all of the Transfer Securities, at a price not lower than the Transfer Price and on terms no more favorable to the transferee than those contained in the Transfer Notice, to any third party; PROVIDED, HOWEVER, that no Transfer may be made to any third party unless and until such third party delivers to the Company an executed consent in the form of EXHIBIT B hereto. Promptly after any Transfer pursuant to this Section 3.3, the Transferring Stockholder shall notify the Company of the consummation thereof and shall furnish such evidence of the completion and time of completion of such Transfer and of the terms thereof as the Company may request. If, at the end of such 90 day period, the Transferring Stockholder has not completed the Transfer of the Transfer Securities, the Transferring Stockholder shall no longer be permitted to Transfer such Securities pursuant to this Section 3.3(e) without again complying with this Section 3.3 in its entirety. If the Transferring Stockholder determines at any time within such 90 day period that the Transfer of such Transfer Securities at a price not lower than the Transfer Price and on terms no more favorable to the transferee than those contained in the Transfer Notice is impractical, such Stockholder may terminate all attempts to Transfer such Transfer Securities and recommence the procedures of this Section 3.3 in their entirety without waiting for the expiration of such 90 day period by delivering written notice of such decision to the Company. (f) Transfers of Shares or Convertible Securities for property other than cash are not permitted pursuant to this Section 3.3. 3.4. RESTRICTIONS IN CONNECTION WITH REGISTRATIONS. Each Stockholder agrees not to effect any sale or other transfer of Shares or Convertible Securities, during the seven days prior to the effective date of a registration statement effected pursuant to the terms of the Joint Venture Agreement and during such period of time beginning on such effective date as may be required by the underwriters of such offering and agreed to by the Company, but in no event exceeding 180 days (in each case except as part of such registration). Each Stockholder hereby acknowledges that such Stockholder shall have no right to include its Shares or Convertible Securities in any registration of Shares or Convertible Securities, except as expressly provided in Article 6 hereof. -9- 3.5. BRING ALONG. (a) BRING ALONG RIGHT. If, after complying with the right of first refusal procedures contained in Section 3.3, any Stockholder wishes to Transfer any Shares or Convertible Securities (other than any Transfer (i) pursuant to Section 3.2 or (ii) through a sale in a registered offering or through the right to sell securities provided by this Section 3.5), then such Stockholder must, as a condition to such Transfer, permit each Founder (or the other Founder if such selling Stockholder is a Founder) (for the purposes of this Section 3.5(a), individually a "REMAINING STOCKHOLDER" and collectively the "REMAINING STOCKHOLDERS") (or cause each such Remaining Stockholder to be permitted) to sell (either to the prospective purchaser of the selling Stockholder's Shares or to another financially reputable purchaser reasonably acceptable to such Remaining Stockholder) the same proportion of the Shares then owned by such Remaining Stockholder as the proportion that the number of Shares the selling Stockholder proposes to sell held by him on the date of the Transfer Notice bears to the total number of Shares held by him on such date, on substantially equivalent terms and at a substantially equivalent price to that offered by the third party offeror taking into account any difference in the type of securities (i.e., Preferred Stock, Common Stock or Convertible Securities) held by the selling Stockholder and the Remaining Stockholders who desire to sell Shares. All numbers of Shares under this Section 3.5 and Section 3.6 shall be determined on the basis of full conversion, exchange or exercise of all Convertible Securities. (b) NOTICE. Each Stockholder's obligation under Section 3.5(a) to afford each of the Remaining Stockholders (or to cause each of them to be afforded) the rights referred to herein will be discharged if the Remaining Stockholders are given written notice hereof simultaneously with the giving of the Transfer Notice required by Section 3.3 and if such notice provides that each of the Remaining Stockholders may elect to avail himself of such rights by a written reply given on or before the expiration of the time period referred to in Section 3.3, addressed to such Person as may be designated in the Transfer Notice. ARTICLE 4. LIMITED FIRST REFUSAL RIGHTS 4.1 ANTI-DILUTION PROVISION. Except for the issuance of Shares and Convertible Securities (i) pursuant to any Public Sale, (ii) upon the conversion of Convertible Securities, (including, without limitation, the -10- Convertible Note and the Wave Warrant), (iii) to employees, directors or consultants of the Company in consideration for their service or continued service to the Company, (iv) as consideration for acquisitions by the Company of the assets or business of another Person or entity, (v) for the establishment of corporate relationships for purposes other than raising capital (including, without limitation, joint ventures and corporate partnerships), and (vi) as a dividend on the outstanding Shares, if the Company authorizes the issuance of any Shares or Convertible Securities (collectively, "FIRST REFUSAL SECURITIES"), the Company will first offer to sell to each Founder a portion of such First Refusal Securities equal to the percentage determined by dividing (A) the number of Common Stock Equivalents held by such Founder and such Founder's Affiliates and the employees, officers, directors and consultants of such Founder and such Founder's Affiliates, BY (B) the number of Common Stock Equivalents then outstanding. Each Founder will be entitled to purchase all or part of such First Refusal Securities at the same price and on the same terms as such stock or securities are to be offered to any other Persons. 4.2 FOUNDERS' EXERCISE OF RIGHT. Each Founder must exercise its purchase rights under this Article 4 within 15 days after receipt of a written notice from the Company describing in reasonable detail the First Refusal Securities being offered, the purchase price thereof, the payment terms and such Founders' percentage allotment. If all of the First Refusal Securities offered to the Founders are not fully subscribed by the Founders, the First Refusal Securities which are not so subscribed for will be reoffered to the Founders purchasing their full allotment upon the terms set forth in this paragraph, except that such Founders must exercise their purchase rights within five (5) days after receipt of such reoffer. 4.3 COMPANY'S EXERCISE OF RIGHT. Upon the expiration of the offering periods described above, the Company will be free to sell such First Refusal Securities which the Founders have not elected to purchase during the 60 days following such expiration on terms and conditions no more favorable to the purchasers thereof than those offered to the Founders. Any First Refusal Securities offered or sold by the Company after such 60-day period must be reoffered to the Founders pursuant to the terms of this Article 4. 4.4 ASSIGNMENT. The rights of any Founder under Section 4.2 may be assigned by such Founder to any Affiliate of such Founder or to any employee, officer, director or consultant to such Founder or to such Founder's Affiliates. -11- ARTICLE 5. TERMINATION 5.1. This Agreement will terminate upon the earlier to occur of (i) the completion of any voluntary or involuntary liquidation or dissolution of the Company, and (ii) the completion of a Qualified Public Offering and the expiration of all lock-up periods in such Qualified Public Offering. ARTICLE 6. MISCELLANEOUS 6.1. CERTIFICATE LEGEND. Upon execution of this Agreement, the certificates representing Shares and Convertible Securities held by the Stockholders shall contain substantially the following legend, in addition to any other legends deemed appropriate or necessary by the Company: This certificate is transferable only upon compliance with and subject to the provisions of a Stockholder Agreement among the Company, its stockholders and their respective spouses, a copy of which Agreement is on file in the office of the Secretary of the Company at its principal place of business. The Company will furnish a copy of such Agreement to the record holder of this Certificate, without charge, upon written request to the Company at its principal place of business or registered office. 6.2.

ENFORCEMENT. No Shares or Convertible Securities shall be transferred on the books of the Company and no sale, assignment, transfer, pledge or other disposition thereof shall be effective unless and until the terms and provisions of this Agreement are complied with, and in cases of violation of this Agreement by the attempted transfer of the Shares or Convertible Securities without compliance with the terms and provisions thereof, such sale, assignment, transfer, pledge or other disposition shall be invalid and of no effect, and the Company and/or any of the Stockholders who are not attempting to transfer the Shares or Convertible Securities shall have the right to compel the Stockholder who is attempting to transfer the Shares -12- or Convertible Securities, and/or the purported transferee, to transfer and deliver the same in accordance with the applicable provisions of this Agreement. 6.4. SPECIFIC PERFORMANCE. The parties hereto recognize that the Company's Shares and Convertible Securities cannot be readily purchased or sold on the open market and that it is to the benefit of the Company and the Stockholders that this Agreement be carried out; and for those and other reasons, the parties hereto would be irreparably damaged if this Agreement is not specifically enforced in the event of a breach hereof. If any controversy concerning the rights or obligations to purchase or sell any Shares and Convertible Securities arises, or if this Agreement is breached, the parties hereto hereby agree that remedies at law might be inadequate and that, therefore, such rights and obligations, and this Agreement, shall be enforceable by specific performance. The remedy of specific performance shall not be an exclusive remedy, but shall be cumulative of all other rights and remedies of the parties hereto at law, in equity or under this Agreement. 6.5. TRANSFEREES AND FUTURE STOCKHOLDERS. The Company and the Stockholders shall cause any transferee of any Shares or Convertible Securities that is not already a party to this Agreement and any future Stockholder of the Company to execute a consent in the form attached as EXHIBIT B hereto, prior to or simultaneously with such transfer, to be bound by the terms and conditions of the Agreement. Upon execution thereof, provided such transfer shall not have been made in contravention of this Agreement, such Stockholder shall be entitled to the rights of an owner of the Shares or Convertible Securities held by such Stockholder hereunder, provided that the foregoing shall not apply to Shares or Convertible Securities that have been sold pursuant to an effective registration statement under the Securities Act or Rule 144 thereunder. 6.6.

If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term hereof, such provisions shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision never comprised a part hereof; and the remaining provisions hereof shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance here from. Furthermore, in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as part of this Agreement, a provision as similar in its terms to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable. 6.10. ENTIRE AGREEMENT. This Agreement embodies the entire agreement and understanding between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to the subject matter hereof. 6.11. COUNTERPARTS. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one instrument. -14- 6.12. AMENDMENTS. No modification, amendment of waiver of any provision of this Agreement will be effective against the Company or the Stockholders unless such modification, amendment or waiver is approved in writing by the holders of at least 80% of the total number of then outstanding Shares held by the Stockholders; PROVIDED, HOWEVER, that (i) no amendment, modification or waiver of any provision of this Agreement that could materially adversely affect the rights of the Founders hereunder in a manner different from the rights of the other Stockholders shall be effective against such Founders without their written consent, and (ii) no amendment, modification or waiver of any provision of this Agreement that could materially adversely affect the rights of the other Stockholders hereunder in a manner different from the rights of the Founders shall be effective against such other Stockholders unless approved in writing by the holders of a majority of the Shares held by such other Stockholders constituting Common Stock. The failure of any party to enforce any of the provisions of this Agreement will in no way be construed as a waiver of such provisions and will not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms. 6.13. CAPTIONS. The captions of this Agreement are for convenience of reference only and shall not limit or otherwise affect any of the terms or provisions hereof. 6.14. PRONOUNS.
