RESTRICTIONS ON TRANSFER; INVESTOR PARTICIPATION IN SALES      3.1. Restrictions on Transfer. The Investors hereby agree to the following provisions with respect to any Transfer of Common Shares or Preferred Shares:

7

     (a) Non-Complying Transfers Prohibited. Each Investor understands and agrees that it may not Transfer any Common Shares or Preferred Shares, whether voluntarily or involuntarily, by operation of law or otherwise, except in accordance with this Agreement. Any such purported Transfer in violation of any provision of this Agreement and all actions by the purported transferor and transferee in connection therewith shall be of no force or effect and the Company shall not be required to recognize any such purported Transfer for any purpose, including without limitation for purposes of dividend and voting rights. If any Transfer of Common Shares or Preferred Shares is made or attempted contrary to the provisions of this Agreement or if any Common Shares or Preferred Shares are not offered as required by this Agreement, the Preferred Stockholders shall have the right to purchase such Common Shares or Preferred Shares, as the case may be, from each such transferring Investor or each such transferee at any time before or after each such purported Transfer in the manner hereinafter described. In addition to any other legal or equitable remedies the Company or the Preferred Stockholders may have, such Preferred Stockholders may enforce this right by actions for specific performance, to the extent permitted by law.      (b) Right of First Offer.      (i) Notice. In the event that an Investor (hereafter the “Selling Stockholder”) desires to Transfer in a single transaction or a series of transactions any Common Shares or Preferred Shares (“Offered Shares”), other than pursuant to a Transfer to a Permitted Transferee (as defined in Section 3.2 below), the Selling Stockholder shall give written prior notice (the “Selling Stockholder’s Notice”) of such desire to the Company and the Preferred Stockholders. The Selling Stockholder’s Notice shall specify (A) the name and address of the party to which the Selling Stockholder desires to sell or otherwise transfer the Offered Shares (the “Proposed Transferee”), (B) the number and denomination of the shares comprising the Offered Shares and, with respect to each denomination included among the Offered Shares, the consideration per share to be delivered to the Selling Stockholder therefor and (C) all other material terms and conditions of the proposed transaction, which must be bona fide.      (ii) Election. Not later than thirty (30) days after receipt of the Selling Stockholder’s Notice (the “Offer Period”), each Preferred Stockholder may deliver written notice (a “Purchasing Stockholder’s Notice”) to the Selling Stockholder stating that such Preferred Stockholder (a “Purchasing Stockholder”) has accepted the offer for its pro rata share (rounded to the nearest whole number, calculated on the basis of the number of shares of Underlying Common Stock held be each Preferred Stockholder other than the Selling Stockholder) of each denomination of shares included among the Offered Shares. Except as described below, each Preferred Stockholder may only accept the offer of the Selling Stockholder for its pro rata share in whole and may not accept such offer in part. Each Preferred Stockholder shall also have a right of oversubscription such that if any Preferred Stockholder fails to accept the offer of the Selling Stockholder as to its full pro rata share, the remaining Preferred Stockholders shall, among them, have the right to purchase up to the balance of such Offered Shares not so purchased. Each Preferred Stockholder may exercise such right of oversubscription by accepting the offer of the Selling Stockholder as to more than its pro rata share of any one or more of the denominations of shares included among the Offered Shares. If, as a result thereof, such

8

oversubscriptions exceed the total number of any one or more of the denominations of shares available in respect of such oversubscription privilege, the oversubscribing Preferred Stockholders shall be cut back with respect to oversubscriptions on a pro rata basis in accordance with their respective pro rata shares (as described above) or as they may otherwise agree among themselves. If any Preferred Stockholder accepts the offer of the Selling Stockholder, such Preferred Stockholder’s Notice shall fix a time, location and date for the closing of such purchase, which date shall be not less than ten (10) nor more than thirty (30) days after delivery of the Preferred Stockholder’s Notice.      (iii) Closing. The place for the closing of any purchase and sale described in Section 3.1(b)(ii) shall be the principal office of the Company or such other place as the parties shall agree. At the closing, the Selling Stockholder shall accept payment on the monetary terms contained in the Selling Stockholder’s Notice. At the closing, the Selling Stockholder shall deliver to the Preferred Stockholder(s) certificates for the portion of the Offered Shares being purchased by such Preferred Stockholder(s), accompanied by duly executed instruments of transfer.      (c) Transfer to Proposed Transferee.      If the Preferred Stockholders fail to elect to purchase all of the Offered Shares, or if such offer is accepted but the Preferred Stockholders fail to consummate the purchase at a closing as hereinabove provided, then the Selling Stockholder shall be free, subject to the provisions of Sections 3.1(d) and 4.2, to sell all, but not less than all, of the remaining Offered Shares (the “Residual Shares”) to the Proposed Transferee on the terms described in the Selling Stockholder’s Notice, provided, however, that such sale is consummated within ninety (90) days after the giving of the Selling Stockholder’s Notice to the Company and the Preferred Stockholders. As a condition precedent to the effectiveness of a Transfer pursuant to this Section 3.1(c), the Proposed Transferee, if the Proposed Transferee should purchase Common Shares not issued upon conversion of Preferred Shares, shall agree in writing prior to such Transfer to become a party to this Agreement as an Initial Stockholder, and, if the Proposed Transferee should purchase Preferred Shares or Common Shares issued on account or upon conversion of Preferred Shares, shall agree in writing prior to such Transfer to become a party to this Agreement as a Preferred Stockholder, and be bound by the terms of this Agreement as an Initial Stockholder or a Preferred Stockholder, as the case may be, and shall thereafter be permitted to Transfer Common Shares and Preferred Shares only in accordance with this Agreement. Notwithstanding anything to the contrary contained in this Section 3.1(c), in the event Ashton is the Selling Stockholder and the Preferred Stockholders do not elect to purchase all of the Common Offered Shares desired to be sold by Ashton, then Ashton shall be free, subject to the provisions of Section 4.2 hereof, to sell all, but not less than all, of its Offered Shares to a third party only if such third party is a reputable institutional investor approved by the Supermajority Preferred Stockholders, which approval shall not be unreasonably withheld at, a price and on terms no less favorable to Ashton than described in Ashton’s Selling Stockholder’s Notice; provided, however, that such sale is consummated within ninety (90) days after the giving of the Selling Stockholder’s Notice by Ashton to the Company and the Preferred Stockholders.

9

     (d) Right of Co-Sale.      Should the Offered Shares constitute at least one percent (1%) of the Stock, each Preferred Stockholder that is not a Purchasing Stockholder shall have an option, exercisable for a period of fifteen days from the date of expiration of the Offer Period (the “Co-sale Period”), to elect to participate in the sale of Residual Shares and to sell, on the terms as set forth in the Selling Stockholder’s Notice, including at the same price per share on a common-equivalent basis, up to an equivalent proportion of the shares of Stock owned by such Preferred Stockholder as the proposed sale of Offered Shares represents with respect to the shares of Stock owned by the Selling Stockholder on the date of the Notice. Such option shall be exercised by delivery of written notice to the Selling Stockholder. Any Preferred Stockholder submitting such a notice is hereinafter referred to as a “Participating Stockholder.” The Selling Stockholder shall use its best efforts to interest the Proposed Transferee in purchasing, in addition to the Residual Shares, the shares of stock the Participating Stockholders wish to sell. If the Proposed Transferee does not wish to purchase all of the shares of stock made available by the Selling Stockholder and the Participating Stockholders, then each Participating Stockholder and the Selling Stockholder shall be entitled to sell, on the terms and conditions set forth in the Notice, at the same price per share on a common-equivalent basis, and at the same time as the sale of the Residual Shares by the Selling Stockholder, a portion of the Shares being sold to the Proposed Transferee, in the same proportion as, (i) in a case where the Offered Shares are Common Shares, such Selling Stockholder’s ownership of Common Shares or such Participating Stockholder’s ownership of shares of Underlying Common Stock bears to the sum of (a) the Common Shares held by the Selling Stockholder and (b) the shares of Underlying Common Stock held by the Participating Stockholders, and (i) in a case where the Offered Shares are Preferred Shares, such Selling Stockholder’s or such Participating Stockholder’s ownership of shares of Underlying Common Stock bears to the shares of Underlying Common Stock held by the Selling Stockholder and the Participating Stockholders.      (e) Transfers of Common Shares and Preferred Shares. In the event that Offered Shares include both Common Shares and Preferred Shares, the proposed sale of Common Shares, on one hand, and Preferred Shares, on the other, shall be treated as separate transactions for the purposes of this Section 3.1.      (f) No Transfers of Rights or Interests. Each Investor understands and agrees that he may not Transfer any interest in or rights to any share of stock, whether voluntarily or involuntarily, by operation of law or otherwise, except pursuant to a Transfer of all rights and interests in such shares of stock made in accordance with this Agreement.      3.2. Transfers to Permitted Transferees. The restrictions on Transfer contained in Section 3.1 shall not apply to (a) Transfers by an Investor to an Affiliate of such Investor, (b) if the Transferring Investor is a partnership, Transfers to a partner or retired partner of such partnership, (c) if the Transferring Investor is a corporation or limited liability company or any equivalent thereof, Transfers to up to an aggregate of twenty-five of the stockholders or members (or their equivalents) of such corporation or limited liability company, (d) Transfers to any nominee of the Transferring Investor made solely for internal administrative purposes, (e) Transfers by an individual to such person’s spouse, children or other member of such person’s immediate family, or to a trust for the benefit of such persons, (f) Transfers by an individual to

Sale of the Company.      (a) If the Board and the Supermajority Preferred Stockholders approve a Sale of the Company (an “Approved Sale”), each holder of Equity Securities shall vote for, consent to and raise no objections against such Approved Sale. If an Approved Sale is structured as a (i) merger or consolidation, each holder of Equity Securities shall waive any dissenters rights, appraisal rights or similar rights in connection with such merger or consolidation or (ii) sale of stock, each holder of Equity Securities shall agree to sell all of his Equity Securities on the terms and conditions approved by the Board and the Supermajority Preferred Stockholders. Each holder of Equity Securities shall take all necessary or desirable actions in connection with the consummation of an Approved Sale as requested by the Board or the Supermajority Preferred Stockholders.      (b) The obligations of the holders of Equity Securities with respect to an Approved Sale of the Company are subject to the satisfaction of the following conditions: (i) upon the consummation of such Approved Sale, each holder of Common Stock shall receive the consideration specified in Section 3.3(c); (ii) if any holders of a class of Common Stock are given an option as to the form and amount of consideration to be received, each holder of such class of Common Stock shall be given the same option; and (iii) each holder of then currently. exercisable options or warrants for the purchase of shares of stock or securities then convertible into Common Shares shall be to (A) exercise such options or warrants or convert such securities, as the case may be, prior to or in connection with the consummation of such Approved Sale and participate in such sale as a holder of Common Stock of the class for which such options or warrants are exercisable or into which such convertible securities are convertible or (B) upon the consummation of such Approved Sale, receive in exchange for such options, warrants or convertible securities consideration equal to the amount determined by multiplying (1) the consideration per share of the class of Common Stock for which such options or warrants are exercisable or into which such convertible securities are convertible to be received by holders of such class of Common Stock in connection with such Approved Sale, less the mean exercise or conversion price per share, as the case may be, of such options, warrants or convertible securities, by (2) the number of shares of such class of Common Stock issuable upon exercise or conversion of such warrants, options or convertible securities.      (c) Upon the consummation of an Approved Sale, all of the Investors shall receive the same proportion (which need not be in the same form) of the aggregate consideration from such Approved Sale that such Investors would have received had such aggregate consideration been distributed by the Company in complete liquidation pursuant to the rights and preferences set forth in the Company’s Certificate of Incorporation as in effect immediately prior to such Approved Sale.

The fees of any other purchaser representative shall be paid by the Investors appointing such purchaser representative.      3.4. Termination.

SUCH SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO DISTRIBUTION OR RESALE. SUCH SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, DELIVERED AFTER SALE, TRANSFERRED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT COVERING SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933 AND ANY OTHER APPLICABLE SECURITIES LAWS, UNLESS THE HOLDER SHALL HAVE OBTAINED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER HEREOF

12

THAT SUCH REGISTRATION IS NOT REQUIRED OR THE TRANSFEREE IS AN AFFILIATE OF THE HOLDER” “THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A CERTAIN FOURTH AMENDED AND RESTATED INVESTOR RIGHTS . AGREEMENT, DATED AS OF SEPTEMBER _, 2003, AMONG THE ISSUER OF SUCH SECURITIES AND CERTAIN OF SAID ISSUER’S STOCKHOLDERS, AS AMENDED, RESTATED AND MODIFIED FROM TIME TO TIME.

OF THE ISSUER OF SUCH SECURITIES, AS AMENDED, RESTATED AND MODIFIED FROM TIME TO TIME. A COPY OF SUCH CERTIFICATE OF INCORPORATION SHALL BE FURNISHED WITHOUT CHARGE BY SAID ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”      Upon request of a holder of such a certificate, the Company shall remove the first legend above from the certificate or issue to such holder a new certificate therefor free of any transfer legend, if there is an effective registration statement covering the securities represented by such certificate or, with such request, the Company shall have received either an opinion in the form prescribed in Section 4.2(a) or a “no-action” letter of the type described to in Section 4.2(b).      4.2. Notice of Proposed Transfer.      Prior to any Transfer of Shares, the holder thereof shall give written notice to the Company of its intention to effect such Transfer. Each such notice shall be in the form prescribed in Section 3.1(b)(i) and, if requested by the Company, shall be accompanied by either. (a) an opinion of counsel reasonably satisfactory to the Company to the effect that the proposed Transfer may be effected without registration under the Securities Act or (b) a “no action” letter from the Commission to the effect that the distribution of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such stock shall be entitled to transfer such stock in accordance with the terms of its notice, but subject to Article 3; provided, however, that no such opinion of counsel shall be required for (i) a transfer by an Investor pursuant to Section 3.2 herein or (ii) a distribution to one or more partners of the transferor (in the case of a transferor that is a partnership) or to a stockholder or member (or equivalents) of the transferor (in the case of a transferor that is a corporation, a limited liability company or an equivalent) in each case in respect of the beneficial interest of such partner, member, stockholder (or equivalent stakeholder). Each certificate for Shares transferred as above provided shall bear the appropriate restrictive legend set forth in Section 4.1, except that such certificate shall not bear such legend if (y) such Transfer is in accordance with the provisions of Rule 144 (or any other rule permitting public sale without registration under the Securities Act) or (z) the opinion-of counsel or “no-action” letter referred to above is to the further effect that the transferee and any subsequent

13

transferee (other than an affiliate of the Company) would be entitled to transfer such securities in a public sale without registration under the Securities Act. Notwithstanding any other provision hereof, the restrictions provided for in this Section 4.2 shall not apply to securities which are not required to bear the legend prescribed by Section 4.1 in accordance with the provisions of that Section. Notwithstanding any other provision hereof, no Transfer to any person who is engaged in a business activity competitive with the Company (as reasonably determined by the Board) shall be permitted without the written authorization of the Board.      4.3. Required Registration.      (a) At any time and from time to time after the date hereof, the Supermajority Preferred Stockholders may request the Company to register for sale under the Securities Act all or any portion of the shares of the Preferred Stockholder Registrable Securities held by such requesting holder or holders for sale in the manner specified in such notice on Form S-1 or any similar long-form registration form.      (b) Following receipt of any notice under Section 4.3(a), the Company shall immediately notify all holders of Registrable Securities from whom notice has not been received and such holders shall then be entitled within thirty (30) days after receipt of such notice from the Company to request the Company to include in the requested registration all or any portion of their shares of Registrable Securities. The Company shall use reasonable best efforts to register under the Securities Act, for public sale in accordance with the method of disposition specified in the notice from requesting holders described in Section 4.3(a), the number of shares of Registrable Securities specified in such notice (and in all notices received by the Company from other holders within thirty (30) days after the receipt of such notice by such holders). The Company shall be obligated to register the Registrable Securities pursuant to this Section 4.3 on three (3) occasions only, provided, however, that such obligation shall be deemed satisfied only when a registration statement covering all shares of Registrable Securities specified in notices received as aforesaid (except to the extent reduced (but not by more than 25%) by the managing underwriter, if any, pursuant to Section 4.3(d)), for sale in accordance with the method of disposition specified by the requesting holders, shall have become effective and, if such method of disposition is a firm commitment underwritten public offering, all such shares shall have been sold pursuant thereto. Notwithstanding anything to the contrary contained herein, during the period between the effective date of a registration statement filed by the Company covering a firm commitment underwritten public offering and prior to the later to occur of the completion of the period of distribution for such offering or 180 days after the effective date of such registration statement, no request maybe made under this Section 4.3.      (c) If the holders requesting such registration intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to Section 4.3(a) and the Company shall include such information in the written notice referred to in Section 43(b). If such method of disposition is an underwritten public offering, the right of any holder to registration pursuant to this Section 4.3 shall be conditioned upon such holder’s agreeing to participate in such underwriting and to permit inclusion of such holder’s Registrable Securities in such underwriting. If such method of disposition is an underwritten public offering, the Supermajority Preferred Stockholders shall designate the managing underwriter of such offering,

14

which managing underwriter shall be reasonably acceptable to the Company. A holder may elect to include in such underwriting all or a part of the Registrable Securities it holds, provided, that the portion of such securities that shall be included in such underwriting shall be subject to reduction as set forth in Section 4.3(d).      (d) A registration statement filed pursuant to this Section 4.3 may, subject to the following provisions, include (i) shares of Common Stock for sale by the Company for its own account, (ii) shares of Common Stock held by officers or directors of the Company and (iii) shares of Common Stock held by other Persons who are entitled to include such shares in such registration (the “Other Shareholders”), in each case for sale in accordance with the method of disposition specified by the requesting holders. If such registration shall be underwritten, the Company, such officers and directors and the Other Shareholders proposing to distribute their shares through such underwriting shall join with the holders of Registrable Securities proposing to distribute their shares through such underwriting in entering into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting. The terms of such underwriting agreement shall be no less favorable to such officers, directors or Other Shareholders than the terms afforded the holders of Registrable Securities. If and to the extent that the managing underwriter determines that marketing factors require a limitation on the number of shares to be included in such registration, then, unless the Company, holders of a majority of the Class C Preferred and holders of a majority of the Junior Preferred shall have otherwise agreed in writing, shares shall be excluded from such registration to the extent so required by such managing underwriter and such exclusion shall be applied (A) first, to the shares held by the Other Shareholders, (B) second, to the shares held by the directors and officers of the Company, (C) third, to the shares to be included in the registration by the Company for its own account (D) fourth, to the Initial Registrable Securities, (E) fifth, to the Preferred Stockholder Registrable Securities relating to the Junior Preferred and (F) sixth, to the Preferred Stockholder Registrable Securities relating to the Class C Preferred. If the managing underwriter determines that marketing factors require a limitation of the number of shares of any of the categories described in clauses (A) — (D) above to be registered under this Section 4.3, then shares of such category shall be excluded in such manner that the shares of such category to be sold shall be allocated pro rata among the selling holders of such category of shares pro rata based on their ownership of such category of shares. No Registrable Securities or any other security excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. If any holder of Registrable Securities, officer, director or Other Shareholder who has requested inclusion in such registration as provided above, disapproves of the terms of the underwriting, such holder of securities may elect to withdraw therefrom by written notice to the Company and the managing underwriter. The securities so withdrawn shall also be withdrawn from registration. Except for registration statements on Form S-0, X-0 xr any comparable form or successor thereto, the Company will not file with the Commission any other registration statement, whether for its own account or that of other stockholders, from the date of receipt of a notice from requesting holders pursuant to this Section 4.3 until the completion of the period of distribution of the registration contemplated thereby or 180 days after the effective date of such registration, whichever is later.      (e) If at the time of any request to register Registrable Shares by holders pursuant to this Section 4.3, the Company is engaged or has plans to engage in a registered public offering or is engaged in any other activity which, in the good faith determination of the Board, would be

15

adversely affected by the requested registration, then the Company may at its option direct that such request be delayed for a period not in excess of 90 days from the date of such request, such right to delay a request to be exercised by the Company not more than twice in any 12-month period and in no event before the 90th day following the last day of any previous period during which registration has been delayed.      4.4. Incidental Registration. If the Company at any time (other than pursuant to Section 4.3 or 4.5) proposes to register any of its securities under the Securities Act for sale to the public, whether for its own account or for the account of other security holders or both (except with respect to registration statements on Forms S-0, X-0 xr any successor to such forms or another form not available for registering the Registrable Securities for sale to the public), each such time it will promptly give written notice to all holders of the Registrable Securities of its intention so to do. Upon the written request of any such holder, received by the Company within thirty (30) days after the giving of any such notice by the Company, to register any or all of its Registrable Securities, the Company will use reasonable best efforts to cause the Registrable Securities as to which registration shall have been so requested to be included in the securities to be covered by the registration statement proposed to be filed by the Company, all to the extent requisite to permit the sale or other disposition by the holder (in accordance with its written request) of such Registrable Securities so registered. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the holders of Registrable Securities as a part of the written notice given pursuant to this Section 4.4. In such event the right of any holder of Registrable Securities to registration pursuant to this Section 4.4 shall be conditioned upon such holder’s participation in such underwriting to the extent provided herein. All holders of Registrable Securities proposing to distribute their securities through such underwriting shall (together with the Company and the Other Shareholders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for underwriting by the Company. Notwithstanding any other provision of this Section 4.4, if the underwriter determines that marketing factors require a limitation on the number of shares to be underwritten, the Company shall so advise all holders of securities requesting registration of any limitations on the number of shares to be underwritten, and the shares that are included in the registration and underwriting shall be (a) in a primary registration on behalf of the Company (i) first, the shares of Common Stock being sold by the Company for its own account (ii) second, . the Preferred Stockholder Registrable Securities relating to the Class C Preferred, (iii) third, the Preferred Stockholder Registrable Securities relating to the Junior Preferred, and (iv) fourth, the Initial Registrable Securities and all other securities held by Persons to which the Company has granted the right to participate in such primary registration, and (b) in a secondary registration on behalf of holders of the Company’s securities (i) first, the securities requested to be included therein by the holders requesting such registration; provided, that the agreement granting such holders registration rights expressly grants such holders the right to participate prior to the holders of Registrable Securities and other securities of the Company, (ii) second, the Preferred Stockholder Registrable Securities relating to the Class C Preferred, (iii) third, the Preferred Stockholder Registrable Securities relating to the Junior Preferred, and (iv) fourth, the initial Registrable Securities and all other securities requested to be included in such registration. If the managing underwriter determines that marketing factors require a limitation of the number of shares of any of the categories described in clauses (i) — (iv) of either part (a) or (b) above to be registered under this Section 4.4, then shares of such category shall be excluded in such manner

16

that the shares of such category to be sold shall be allocated among the selling holders of such category of shares pro rata based on their ownership of such category of shares. Notwithstanding the foregoing provisions, the Company may withdraw any registration statement referred to in this Section 4.4 without thereby incurring any liability to the holders of Registrable Securities. If any holder of Registrable Securities disapproves of the terms-of any such underwriting, it may elect to withdraw therefrom by written notice to the Company and the underwriter. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration.      4.5. Registration on Form S-2 or S-3.      (a) In addition to the rights provided in Sections 43 and 4.4, subject to a limit of one (1) registration hereunder in any twelve (12) month period, if at any time and from time to time after the date on which the Company is a registrant entitled to use Form S-2 or S-3 or any comparable or successor form thereto to register such shares, any holder or group of holders of Registrable Securities may request that the Company file a registration statement on Form S-2 or S-3 or any comparable or successor form thereto for a public offering of all or any portion of the shares of Registrable Securities held by such requesting holder or holders, then the Company shall use reasonable best efforts to register under the Securities Act on Form S-2 or S-3 or any comparable or successor form thereto, for public sale in accordance with the method of disposition specified in such request; provided, that the Company shall be obligated to so register Registrable Securities only in circumstances where the reasonably anticipated aggregate price to the public for the Registrable Securities to be registered equals or exceeds $1,000,000.00. Whenever the Company is required by this Section 4.5 to effect the registration of Registrable Securities, each of the procedures and requirements of Section 4.3, including but not limited to the requirement that the Company notify all holders of Registrable Securities from whom notice has not been received and provide them with the opportunity to participate in the offering as well as the procedures set forth therein regarding the exclusion of shares from an offering, shall apply to such registration, provided, however, that there shall be no limitation on the number of registrations on Form S-2 or S-3 which may be requested and obtained under this Section 4.5.      (b) The Company shall use reasonable best efforts to qualify for registration on Form S-0, X-0 xnd any comparable or successor form or forms; and to that end the Company shall register (whether or not required by law to do so) the Common Stock under the Exchange Act in accordance with the provisions of that Act following the effective date of the first registration of any securities of the Company on Form S-1 or any comparable or successor form.      4.6. Registration Procedures. If and whenever the Company is required by the provisions of Section 4.3, 4.4 or 4.5 to use reasonable best efforts to effect the registration of any Registrable Securities under the Securities Act, the Company will, as expeditiously as possible:      (a) prepare and file with the Commission a registration statement (which, in the case of an underwritten public offering pursuant to Section 4.3, shall be on Form S-1 or other form of general applicability satisfactory to the managing underwriter selected as therein provided) with respect to such securities including executing an undertaking to file post-effective amendments and use reasonable best efforts to cause such registration statement to become and remain effective for the period of the distribution contemplated thereby;

18

meaning of the Securities Act and that, in the opinion of such accountants, the financial statements of the Company included in the registration statement or the prospectus, or any amendment or supplement thereof, comply as to form in all material respects with the applicable accounting requirements of the Securities Act, and such letter shall additionally cover such other financial matters (including information as to the period ending no more than five (5) business days prior to the date of such letter) with respect to such registration as such underwriters reasonably may request;      (i) make available for inspection by each seller of Registrable Securities, any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or other agent retained by any such seller or underwriter, reasonable access to all financial and other records, pertinent corporate documents and properties of the Company, as such parties may reasonably request, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement;      (j) cooperate with the selling holders of Registrable Securities and the managing underwriter, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, such certificates to be in such denominations and registered in such names as such holders or the managing underwriter may request at least two business days prior to any sale of Registrable Securities; and      (k) permit any holder of Registrable Securities which holder, in the sole and exclusive judgment, exercised in good faith, of such holder, might be deemed to be a controlling person of the Company, to participate in good faith in the preparation of such registration or comparable statement and to require the insertion therein of material, furnished to the Company in writing, which in the reasonable judgment of such holder and its counsel should be included.      For purposes of this Agreement, the period of distribution of Registrable Securities in a firm commitment underwritten public offering shall be deemed to extend until each underwriter has completed the distribution of all securities purchased by it, and the period of distribution of Registrable Securities in any other registration shall be deemed to extend until the earlier of the sale of all Registrable Securities covered thereby or 180 days after the effective date thereof, provided, however, in the case of any registration of Registrable Securities on Form S-3 or a comparable or successor form which are intended to be offered on a continuous or delayed basis, such 180 day-period shall be extended, if necessary, to keep the registration statement effective until all such Registrable Securities are sold, provided, that Rule 415, or any successor rule under the Securities Act, permits an offering on a continuous or delayed basis, and provided, further, that applicable rules under the Securities Act governing the obligation to file a post-effective amendment, permit, in lieu of filing a post-effective amendment which (y) includes any prospectus required by Section 10(a)(3) of the Securities Act or (z) reflects facts or events representing a material or fundamental change in the information set forth in the registration statement, the incorporation by reference of information required to be included in (y) and (z) above contained in periodic reports filed pursuant to Section 13 or 15(d) of the Exchange Act in the registration statement.

20

preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof) (any of the foregoing herein called an “Offering Document”), (ii) any blue sky application or other document executed by the Company specifically for that purpose or based upon written information furnished by the Company filed in any state or other jurisdiction in order to qualify any or all of the Registrable Securities under the securities laws thereof (any such application, document or information herein called a “Blue Sky Application”), (iii) any omission or alleged omission to state in any Offering Document or in any Blue Sky Applications executed or filed by the Company, a material fact required to be stated therein or necessary to make the statements therein not misleading, (iv) any violation by the Company or its agents of the Securities Act or any rule or regulation promulgated under the Securities Act applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration, or (v) any failure to register or qualify the Registrable Securities in any state where the Company or any of its agents has affirmatively undertaken or agreed in writing that the Company (the undertaking of any underwriter chosen by the Company being attributed to the Company) will undertake such registration or qualification (provided, that in such instance the Company shall not be so liable if it has used its reasonable best efforts to so register or qualify the Registrable Securities) and will reimburse each such seller, and each such officer, director and partner, each such underwriter and each such controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, promptly after being so incurred, provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with written information furnished by any such seller, any such underwriter or any such controlling person in writing specifically for use in such registration statement or prospectus.      (b) In the event of a registration of any of the Registrable Securities under the Securities Act pursuant to Section 4.3, 4.4 or 4.5, each seller of such Registrable Securities thereunder, severally and not jointly, will indemnify and hold harmless the Company, each officer of the Company who signs the registration statement, each director of the Company, each other seller of Registrable Securities and each such officer, director and partner thereof, each underwriter and each controlling person of any of the foregoing Persons, against all losses, claims, damages or liabilities, joint or several, to which any of the foregoing Persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Offering Document or any Blue Sky Application or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and each other seller, underwriter, officer, director, partner and controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action, promptly after being so incurred, provided, however, that such seller will be liable hereunder in any such case only to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information pertaining to such seller, as such, furnished in writing to the Company by such seller specifically for use in such registration statement or prospectus; and, provided, further, however, that the liability of each seller

21

hereunder shall be limited to the net proceeds received by such seller from the sale of Registrable Securities covered by such registration statement. Not in limitation of the foregoing, it is understood and agreed that the indemnification obligations of any seller hereunder pursuant to any underwriting agreement entered into in connection herewith shall be limited to the obligations contained in this Section 4.8(b).      (c) Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so. to notify the indemnifying party shall not relieve it from any liability which it may have to such indemnified party other than under this Section 4.8 and shall only relieve it from any liability which it may have to such indemnified party under this Section 4.8 if and to the extent the indemnifying party is prejudiced by such omission. In case any such action shall be brought against any indemnified party and the indemnified party shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in and, to the extent it shall wish, assume and undertake the defense thereof with counsel satisfactory to such indemnified party (provided, that the indemnifying party shall acknowledge in writing its undertaking of such defense), and, after notice from the indemnifying party to such indemnified party of its election to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 4.8 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected, provided, however, that, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be reasonable defenses available to it which are different from or additional to those available to the indemnifying party or that the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, the indemnified party shall have the right to select separate counsel and to assume such legal defenses and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the indemnifying party as incurred. No indemnifying party, in the defense of any such claim or action, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or action. Each indemnified party shall furnish such information regarding itself or the claim in question as an indemnifying party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.      (d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (i) any Person makes a claim for indemnification pursuant to this Section 4.8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 4.8 provides for indemnification in such case, or (ii) contribution under the Securities Act maybe required on the part of any Person in circumstances for which indemnification is provided under this Section 4.8, then, and in each such case, the Company and such Person shall contribute to the aggregate losses, claims, damages or liabilities

22

to which they may be subject in such proportion so that such Person shall be responsible for the portion represented by the percentage that the public offering price of such Person’s Registrable Securities offered by the registration statement bears to the public offering price of all securities offered by such registration statement, and the Company shall be responsible for the remaining portion; provided, however, that, in any such case, (A) no such holder of Registrable Securities will be required to contribute any amount in excess of the proceeds received from the sale of all such Registrable Securities offered by it pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.      (e) The indemnities and obligations provided in this Section 4.8 shall survive the transfer of any Registrable Securities.      4.9. Changes in Common Stock. If, and as often as, there is any change in the Common Stock by way of a stock split, stock dividend, combination or reclassification, or through a merger, consolidation, reorganization or recapitalization, or by any other means, appropriate adjustment shall be made in the provisions hereof so that the rights and privileges granted hereby shall continue with respect to the Common Stock as so changed.      4.10. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, at all times after ninety (90) days after any registration statement covering a public offering of securities of the Company under the Securities Act shall have become effective, the Company shall:      (a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act (or any successor rule);      (b) use reasonable best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and      (c) furnish to each holder of Registrable Securities forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of such Rule 144 (or any successor rule) and, at any time after it has become subject to such reporting requirements, of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as such holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such holder to sell any Registrable Securities without registration.      4.11. “Market Stand-Off” Agreement. Each of the Investors agrees, severally and not jointly, if requested by the Company and an underwriter of Common Stock (or other securities) of the Company not to sell or otherwise transfer or dispose of any Common Stock (or other securities) of the Company held by such Investor during a period not to exceed one hundred and eighty (180) days following the effective date of the first registration statement of the Company filed under the Securities Act, and to enter into an agreement to such effect;

23

provided, that (i) all officers and directors of the Company, and all Persons known by the Company to own 1% or more of the Company’s outstanding capital stock, shall enter into similar agreements and (ii) this restriction shall not apply to shares of Common Stock being sold by any Investor under any such registration statement. The Company may impose stop-transfer instructions with respect to the shares (or securities) subject to the foregoing restriction until the end of said period.      4.12. Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Article 4 may be assigned (but only with all related obligations under this Agreement) by a holder of Registrable Securities to a transferee or assignee of such securities (a) who is not engaged in a business activity competitive with the Company (as reasonably determined by the Board) and who after such assignment or transfer, holds at least 50,000 shares of Registrable Securities (subject to appropriate adjustment for stock splits, stock dividends, combinations and similar recapitalization events) or (b) who is an Affiliate, constituent partner or member (or its equivalent) of such holder; provided, the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and provided, further, that such assignment shall be effective only if (i) immediately following such transfer the further disposition of such securities by the transferee or assignee is restricted under the Act and (ii) the transferee or assignee shall acknowledge in writing that the transferred or assigned Registrable Securities shall remain subject to this Agreement. For the purposes of determining the number of shares of Registrable Securities held by a transferee or assignee, the holdings of transferees and assignees of a partnership who are partners or retired partners of such partnership or members (or their equivalents) or limited liability companies (or their equivalents) (including spouses and ancestors, lineal descendants and siblings of such partners or members (or their equivalents) or spouses who acquire Registrable Securities by gift, will or intestate succession) shall be aggregated together and with the partnership or limited liability company (or its equivalent); provided, that all assignees and transferees who would not qualify individually for assignment of registration rights shall have a single attorney-in-fact for the purpose of exercising any rights, receiving notices or taking any action under this Article 4.           5. BOARD      5.1. Election of Directors; Supermajority Requirement for Expansion of Board. Each Investor shall take or cause to be taken such actions as may be required from time to time to establish and maintain the number of persons comprising the Board at seven (7) or at such other number (subject to Section 5.2 and the last sentence of this Section 5.1) as the Board may determine from time to time in accordance with this Section, and to elect as directors: (a) the chief executive officer of the Company; (b) two individuals designated by Dolphin Communications Fund L.P., who initially shall be Xxxx Xxxxx and Xxxxxxxxx Xxxxxxxxx; (c) one individual designated by Xxxxxxx Xxxxxx, who initially shall be Xxxx Xxxxxxx; (d) one individual designated by Deutsche Bank, who initially shall be Xxxxxx Xxxxxxx; (e) one individual designated by AdAstra, who initially shall be Xx. Xxxx Xxxxxxxxx; and (f) one individual who is not an employee of the Company or an Affiliate of any Investor, who has expertise in the Company’s industry and who is acceptable to a majority of the other directors.

Notwithstanding the provisions of this Section 5.4, if any holder(s) fails to designate an individual to fill a directorship pursuant to the terms of this Section 5.4, the individual previously holding such directorship shall be elected to such position, or if such individual fails or declines to serve, the election of an individual to such directorship shall be accomplished in accordance with the Company’s By-laws and applicable law; provided that the Investors shall vote to remove such individual if the holder(s) which failed to designate such directorship so direct(s) (and, if such holder(s) so direct(s), will elect in the removed individual’s place any other individual designated by such holder(s)).      5.5.

     8.2. 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 oral or written agreements and understandings relating to the subject matter hereof, including the Prior Agreement. No statement, representation, warranty, covenant or agreement, of any kind not expressly set forth in this Agreement shall affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement. Nothing contained herein shall prohibit the Company from granting additional registration rights to other present or future holders of securities of the Company, on terms and conditions to be determined by the Board.      8.3. Modifications and Amendments. Except as otherwise provided herein, this Agreement may only be amended or modified, and provision hereof may only be waived, with the prior written consent of the Company, and the Supermajority Preferred Stockholders, and (a) with respect to any amendment, modification or waiver that adversely and prejudicially affects the Initial Stockholders vis-à-vis the Preferred Stockholders, holders of a majority of the Initial Stockholder Shares, and (b) with respect to any amendment, modification or waiver that adversely and prejudicially affects the Class C Preferred, holders of a majority of the Class C Preferred. For the avoidance of doubt, an amendment to add another party to this Agreement is not an action which, in and of itself affects any Initial Stockholder adversely and prejudicially vis-à-vis the Preferred Stockholders. Notwithstanding the foregoing, without the consent of any Investor, the Company may restate any schedule to this Agreement so that it more accurately reflects the holders of securities of the type in question and/or to change the addresses for notice

30

to any Investor at such Investor’s request. Any waiver or consent hereunder shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent      8.4. Assignment. The rights and obligations under this Agreement may not be assigned by the Company without the prior written consent of the Supermajority Preferred Stockholders, unless specifically permitted by the terms hereof, except that the Company may assign this Agreement and its rights and obligations hereunder to any purchaser of all or substantially all of its assets or to any successor corporation resulting from any merger or consolidation of the Company.      8.5. Benefit. All statements, representations, warranties, covenants and agreements in this Agreement shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Except with respect to Section 4.8, pursuant to which each indemnified party described therein is an intended third party beneficiary hereof, nothing in this Agreement shall be construed to create any rights or obligations except among the parties hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement.      8.6. Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed by the law of The Commonwealth of Massachusetts, without giving effect to the conflict of law principles thereof.      8.7. Jurisdiction and Service of Process. Any legal action or proceeding with respect to this Agreement shall be brought in the courts of The Commonwealth of Massachusetts or of the United States of America for the District of Massachusetts. By execution and delivery of this Agreement, each of the parties hereto accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. Each of the parties hereto irrevocably consents to the service of process of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by certified mail, postage prepaid, to the party at its address set forth in Section 8.1 hereof.      8.8. Severability. In the event that any court of competent jurisdiction shall determine that any provision, or any portion thereof, contained in this Agreement shall be unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it enforceable, and as so limited shall remain in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect.      8.9. Interpretation. The parties hereto acknowledge and agree that: (a) each party and its counsel reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision; (b) the rule of construction to the effect that any ambiguities are resolved against the drafting party shall not be employed in the interpretation of this Agreement; and (c) the terms and provisions of this Agreement shall be construed fairly as to all parties hereto and not in favor of or against any party, regardless of which party was generally responsible for the preparation of this Agreement.

31

     8.10. Headings and Captions. The headings and captions of the various subdivisions of this Agreement are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof.      8.11. Enforcement. Each of the parties hereto acknowledges and agrees that the rights acquired by each party hereunder are unique and that irreparable damage would occur in the event that any of the provisions of this Agreement to be performed by the other parties were not performed in accordance with their specific terms or were otherwise breached. Accordingly, in addition to any other remedy to which the parties hereto are entitled at law or in equity, each party hereto shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by any other party and to enforce specifically the terms and provisions hereof in any federal or state court to which the parties have agreed hereunder to submit to jurisdiction.      8.12. No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under this Agreement, and no course of dealing among the parties hereto, shall operate as a waiver of any such right, power or remedy of the party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.      8.13. Counterparts. This Agreement may be executed in one or more counterparts, and by different parties hereto on separate counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.      8.14. Certain Terms. The term Preferred Stockholder as used herein refers to any such Preferred Stockholder in its capacity as a holder of Preferred Shares, Preferred Stockholder Registrable Securities and Underlying Common Stock and as a subscriber for Preferred Stock pursuant to the Exchange Agreement or Class C Purchase Agreement and not in its capacity as a holder of Initial Stockholder Shares or Initial Registrable Securities or as an Initial Stockholder. The term Initial Stockholder refers to any such Initial Stockholder in its capacity as a holder of Initial Stockholder Shares and Initial Registrable Securities and as an Initial Stockholder and not in its capacity as a holder of Preferred Shares, Preferred Stockholder Registrable Securities or Underlying Common Stock or as a subscriber for Preferred Stock pursuant to the Exchange Agreement or the Class C Purchase Agreement.      8.15. Non-cash Consideration. In the event the consideration to be paid for Shares includes non-cash consideration, the dollar value of such non-cash consideration shall be its fair market value as determined, in good faith, by the Supermajority Preferred Stockholders.
