ARTICLE III
RIGHT OF FIRST REFUSAL AND CO-SALE RIGHT
ON PROPOSED TRANSFERS OF SECURITIES

3.1 Right of First Refusal. Each Securityholder hereby grants to (a) each Preferred Stockholder and (b) the Corporation a right of first refusal (a “Right of First Refusal”) to purchase any or all Securities which such Securityholder (the “Selling Securityholder”) may, from time to time, propose to Transfer (other than with respect to a Transfer to a Permitted Transferee).

3.2 Procedure.

(a) In the event a Selling Securityholder wishes to make a Transfer of Securities (other than with respect to a Transfer to a Permitted Transferee), the Selling Securityholder shall deliver written notice (the “Transfer Notice”) to the Corporation specifying, in reasonable detail, (i) its bona fide intention to Transfer such Securities, (ii) the type of Securities to be Transferred, (iii) the number of such Securities to be Transferred, (iv) the proposed price per security therefor and material terms and conditions upon which the proposed Transfer is to be made, (v) the identity of each of the proposed Transferees and (vi) all other information reasonably necessary or requested by the Corporation to fully describe and confirm the bona fide nature of the proposed Transfer. As soon as practicable after the receipt of the Transfer Notice, the Corporation shall distribute such Transfer Notice to each Preferred Stockholder (or, in the case of a Selling Securityholder that is a Preferred Stockholder, to each other Preferred Stockholder) (the “Non-Selling Securityholders”). Each Non-Selling Securityholder shall have fifteen (15) days from the date of the receipt of the Transfer Notice (the “Right of First Refusal Election Period”) to exercise its Right of First Refusal to purchase such Non-Selling Securityholder’s respective Pro Rata Share (but not less than such Non-Selling Securityholder’s Pro Rata Share) of the Securities subject to the Transfer Notice (for the price and upon the terms specified therein). If any Non-Selling Securityholder elects to purchase its respective Pro Rata Share, such Non-Selling Securityholder shall notify the Corporation and the Selling Securityholder within the Right of First Refusal Election Period by written notice (the “Right of First Refusal Election Notice”).

(b) If, after the expiration of the Right of First Refusal Election Period, any Non-Selling Securityholder has not exercised its Right of First Refusal to purchase its respective Pro Rata Share, the Corporation shall, within five (5) days of the expiration of the Right of First Refusal Election Period, provide the other Non-Selling Securityholders with written notice (the “Over-Allotment Notice”) indicating the aggregate amount of Securities as to which all Non- Selling Securityholders shall not have exercised their Rights of First Refusal. Each Non-Selling Securityholder who shall have elected to purchase its full Pro Rata Share of the Securities proposed to be Transferred by the Selling Securityholder shall have ten (10) days upon receipt of the Over-Allotment Notice (the “Over-Allotment Election Period”) to give notice (the “Over-Allotment Election Notice”) to the Corporation and the Selling Securityholder whether it elects to exercise its Over-Allotment Option granted in Section 3.3.

(c) If, after expiration of the Over-Allotment Election Period, the Non-Selling Securityholders in the aggregate have elected not to purchase all of the Securities subject to the

-11-

Transfer Notice, then the Corporation shall have ten (10) days from the expiration of the Over-Allotment Election Period to purchase any or all of the Securities subject to the Transfer Notice and not purchased by the Non-Selling Securityholders by delivering written notice to the Selling Securityholder.

(d) If the Corporation or any Non-Selling Securityholder shall have failed to deliver to the Selling Securityholder or the Corporation written notice with respect to its Right of First Refusal within the time periods described in this Section 3.2, it shall be deemed to have waived the rights described herein.

(e) Settlement for the Securities to be purchased by either the Corporation or any Non-Selling Securityholder pursuant to this Section 3.2 shall be made in cash within fifty (50) days from the Corporation’s deemed date of receipt of the Transfer Notice; provided, however, that if the terms of payment for the Securities specified in the Transfer Notice were for other than cash against delivery, each of the Corporation and the Non-Selling Securityholders may pay to the Selling Securityholder the fair market value of such consideration (as determined in good faith by the Board) in cash.

3.3 Over-Allotment Option. In the event that the Non-Selling Securityholders, in the aggregate, do not purchase all of the Securities offered by the Selling Securityholder pursuant to the Right of First Refusal described in this Article III, then any Non-Selling Securityholder that shall have exercised its Right of First Refusal to purchase its full Pro Rata Share of such Securities shall also have the right (the “Over-Allotment Option”) to purchase up to all of its respective Pro Rata Share among such Non-Selling Securityholders (or such other proportion as may be agreed to by all of the Non-Selling Securityholders that have exercised their Rights of First Refusal) of the remaining Securities (the “Over-Allotment Option Securities”) offered in accordance with this Section 3.3, in addition to such Securities it has already elected to purchase, as provided in Section 3.2(b).

3.4 Co-Sale Rights.

(a) If, after the expiration of the forty (40) day period beginning on the Corporation’s deemed receipt of the Transfer Notice (the “Offer Period”), the Corporation and the Non-Selling Securityholders have not elected to purchase, in aggregate, all of the Securities subject to the Transfer Notice, then each of the Non-Selling Securityholders shall have a co-sale right (a “Co-Sale Right”) to sell, upon the terms and conditions contained in the applicable Transfer Notice and in accordance with the procedures set forth in this Section 3.4 (it being understood that, if more than one class or type of Securities is to be sold, the relative prices of such Securities shall be determined as provided in Section 3.4(d))), to the proposed Transferee up to that number of Securities of the same class or type proposed to be Transferred equal to its Co-Sale Pro Rata Share (as defined below); provided, however, that if the Selling Securityholder is Transferring Common Stock, each of the Non-Selling Securityholders may sell shares of Preferred Stock (the number of which shall be determined on an as-converted basis) to the proposed Transferee; provided further that notwithstanding the immediately preceding proviso, in the event that a Non-Selling Securityholder that wishes to exercise its Co-Sale Right holds Securities of the same class or type proposed to be Transferred by the Selling Securityholder,

-12-

such Non-Selling Securityholder must sell such Securities to the proposed Transferee prior to selling Securities of any other class or type to the proposed Transferee.

(b) Each Non-Selling Securityholder shall have fifteen (15) days from the expiration of the Offer Period (the “Co-Sale Period”) to exercise its Co-Sale Right as provided in this Section 3.4 by delivering written notice (the “Co-Sale Election Notice”) to the Selling Securityholder, with a copy to the Corporation. The Co-Sale Election Notice shall specify the number of Securities that such Non-Selling Securityholder elects to sell (up to such Co-Sale Pro Rata Share). A Non-Selling Securityholder’s failure to deliver a Co-Sale Election Notice with respect to such Securities within the Co-Sale Period shall be deemed a waiver of its Co-Sale Right with respect to the proposed Transfer.

(c) If a prospective Transferee refuses to purchase Securities from a Non-Selling Securityholder exercising its Co-Sale Right hereunder, the Selling Securityholder shall not sell any Securities to such prospective Transferee unless and until, simultaneously with such sale, the Selling Securityholder shall purchase such Securities from the Non-Selling Securityholder for the same consideration (or cash equal to the fair market value thereof as determined in good faith by a majority of the Board) and on the same terms and conditions as the proposed Transfer described in the Transfer Notice.

(d) In the event that a Non-Selling Securityholder has delivered a Co-Sale Election Notice with respect to Securities that are of a class or type other than the class or type being sold by the Selling Securityholder to the proposed Transferee, the price per share to be paid by the proposed Transferee for such Non-Selling Securityholder’s Securities shall be determined in good faith by a majority of the Board and shall be equal on a relative basis to the price per share being paid by the proposed Transferee for the Selling Securityholder’s Securities, taking into account the relative rights and privileges of the respective classes of Securities.

(e) Each Non-Selling Securityholder’s “Co-Sale Pro Rata Share” with respect to any proposed Transfer is that number of Securities equal to the product obtained by multiplying (i) the aggregate number of shares of Common Stock (calculated on a Fully-Diluted Basis) subject to the Transfer Notice by (ii) a fraction, (x) the numerator of which is the number of shares of Common Stock (calculated on a Fully-Diluted Basis) then held by such Non-Selling Securityholder and (y) the denominator of which is the total number of shares of Common Stock then outstanding (calculated on a Fully-Diluted Basis).

3.5 Transfer of Securities upon Failure to Exercise Rights. The Selling Securityholder may, during the 60-day period following the expiration of the Co-Sale Period, conclude a Transfer of any or all of the Securities covered by the Transfer Notice and not otherwise subject to the Right of First Refusal or Co-Sale Right, on terms and conditions the same or the same in all material respects as those described in the Transfer Notice; provided, however, that if the Selling Securityholder fails to consummate the proposed Transfer described in the Transfer Notice during the 60-day period following the expiration of the Co-Sale Period, or if a proposed Transfer is to be consummated on terms that are not the same in all material respects as those disclosed in the Transfer Notice or with a proposed Transferee other than that identified in the Transfer Notice, then the Selling Securityholder shall be required to comply anew with the requirements of this Article III prior to consummating the proposed Transfer.

If the Approved Sale is structured as a (x) merger or consolidation, each Securityholder covenants and agrees to waive any dissenters’ rights, appraisal rights or similar rights in connection with such merger or consolidation, (y) sale of Securities, each Securityholder covenants and agrees to sell all of his, her or its Securities and rights to acquire Securities on the terms and conditions so approved or (z) sale of all or substantially all of the assets of the Corporation, each Securityholder covenants and agrees to approve any subsequent liquidation of the Corporation in connection therewith. In addition, each Securityholder covenants and agrees to take all necessary or desirable actions in connection with the consummation of the Approved Sale as requested by the Board.

(b) Conditions to Drag-Along Obligations. The obligations of the Securityholders described in Section 4.1(a) with respect to an Approved Sale are subject to the satisfaction of the following conditions: (i) upon the consummation of the Approved Sale, each Securityholder shall receive the same portion of the aggregate consideration that such Securityholder would have received if such aggregate consideration had been distributed by the Corporation in complete liquidation pursuant to the rights and preferences set forth in the Certificate of Incorporation as in effect immediately prior to such Approved Sale (giving effect to applicable orders of priority); and (ii) upon the consummation of any such Approved Sale, all of the Securityholders of a particular class of Securities shall receive (or shall have the option to receive) the same form of consideration.

4.2 Indemnification in Approved Sale.

(a) In connection with any Approved Sale, the Securityholders shall be obligated to join on a pro rata basis (based on each such Securityholder’s share of the aggregate proceeds paid with respect to its equity interest in the Corporation) in any indemnification obligation agreed to in connection with such Approved Sale (other than any such obligations that relate specifically to a particular Securityholder such as indemnification with respect to representations and warranties given by a Securityholder regarding such Securityholder’s title to and ownership of Securities); provided, that (x) no such Securityholder shall be obligated in connection with such Approved Sale to indemnify the prospective Transferee or its Affiliates with respect to an amount in excess of the net cash proceeds paid to such Securityholder in connection with such Approved Sale; (y) any escrow of proceeds of any such transaction shall be withheld on a pro rata basis among all Securityholders; and (z) each such Securityholder shall

-14-

pay its Pro Rata Share of the expenses incurred by the Securityholders in connection with such Approved Sale.

(b) Notwithstanding anything contained in this Agreement, in no event will any Securityholder be required to make any representations or warranties in connection with an Approved Sale that are joint and several with any other Securityholder(s) or that pertain to matters other than title to the Common Stock or other securities held by such Securityholder, such Securityholder’s capacity, authority or power to consummate or participate in the transaction in question and other matters peculiar to such Securityholder and customary for the type of transaction being consummated.

ARTICLE V
PREEMPTIVE RIGHTS

5.1 Preemptive Rights.

(a) If the Corporation proposes to issue or sell any New Securities after the date hereof, the Corporation shall notify in writing each Preferred Stockholder (each a “Preemptive Right Holder”) of such proposed transaction (the “Preemptive Right Notice”). The Preemptive Right Notice shall describe the proposed issuance or sale, identify the proposed buyer and contain an offer to sell to each Preemptive Right Holder, at the same price and for the same consideration (subject to the last sentence of this paragraph) to be paid by the proposed buyer, additional New Securities of the same class and type being offered to the proposed buyer in an amount equal to the product obtained by multiplying (i) the number of New Securities being offered to the proposed buyer by (ii) a fraction, (x) the numerator of which is the number of shares of Preferred Stock and Conversion Common Shares held by such Preemptive Right Holder (calculated on a Fully-Diluted Basis) and (y) the denominator of which is the total number of shares of Preferred Stock and Conversion Common Shares then outstanding (on a Fully-Diluted Basis). If the purchase price for the New Securities to be paid by the proposed buyer is in some form other than cash, then a Preemptive Right Holder may pay for the additional New Securities it is entitled to purchase hereunder in cash (with the fair market value of any non-cash consideration to be paid by such buyer to be determined in good faith by the Board). A Preemptive Right Holder shall have fifteen (15) days from the receipt of a Preemptive Right Notice (the “Preemptive Rights Period”) to accept the offer contained in such Preemptive Right Notice, and any purchase of New Securities by a Preemptive Right Holder shall be made within 30 days of receipt of the Preemptive Right Notice by such Preemptive Right Holder.

(b) If any Preemptive Right Holder fails to accept the offer contained in the Preemptive Right Notice within the Preemptive Rights Period, the Corporation shall be entitled to sell such New Securities free of any right on the part of such Preemptive Right Holder under this Section 5.1 during the one hundred eighty (180) days following the expiration of the Preemptive Rights Period at a price not less than, and on other terms and conditions not more favorable than, that offered to such Preemptive Right Holder. Any New Securities offered or sold by the Corporation thereafter must be reoffered to all Preemptive Right Holders, in accordance with the terms of this Section 5.1.
