(a) If at any time a Stockholder or any of his/its Affiliates, other than the Company, desires to Transfer all or any part of their Equity Securities (other than pursuant to Permitted Sales) to any Person (the "Proposed Transferee"), such Stockholder (the "Seller") shall, except as provided below, submit a written offer (the "Offer") to sell such Equity Securities (the "Offered Shares"), first to the Company, and second to the Holders, on the same terms and conditions on which the Seller proposes to sell such Offered Shares to the Proposed Transferee. The parties acknowledge and agree that any Transfer described in the last sentence of Sections 3.3(a) and 3.4(a) shall not be subject to the terms of this Section. The Offer shall disclose the identity of the Proposed Transferee, the Offered Shares proposed to be sold, the terms and conditions, including price, of the proposed sale, and any other material facts relating to the proposed sale. The Offer shall further state that the Company and the Holders may acquire, in accordance with the provisions of this Agreement, all or any portion of the Offered Shares for the price and upon the other terms and conditions, including deferred payment (if applicable), set forth therein. 10 (b) Upon receipt of the Offer, if the Company desires to purchase all or any part of the Offered Shares, the Company shall communicate in writing its election to purchase to the Seller, which communication shall state the number of Offered Shares the Company desires to purchase and shall be given to the Seller in accordance with Section 5.4 below within thirty (30) days of the date the Offer was made. Such notice shall, when taken in conjunction with the Offer, be deemed to constitute a valid, legally binding and enforceable agreement for the sale to, and purchase by, the Company of the number of Offered Shares specified by the Company in such notice and on the terms of the Offer. Sales of the Offered Shares to be sold to the Company pursuant to this Section 3.5(b) shall be made at the offices of the Company on the 45th day following the date the Offer was made (or if such 45th day is not a Business Day, then on the next succeeding Business Day). Such sales shall be effected by the Seller's delivery to the Company of a certificate or certificates evidencing the Offered Shares to be purchased by it, duly endorsed for transfer to the Company, against payment to the Seller of the purchase price therefor by the Company. (c) Each Holder shall, subject to the prior purchase right of the Company, have the absolute right to purchase that number of Offered Shares not purchased by the Company as shall be equal to the number of Offered Shares not purchased by the Company multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock (determined on an as converted basis) then owned by such Holder and the denominator of which shall be the aggregate number of shares of Common Stock (determined on an as converted basis) then owned by all of the Holders. The amount of Offered Shares that each Holder is entitled to purchase under this Section 3.5(c) shall be referred to as its "Pro Rata Fraction." The Holders shall have a right of oversubscription such that if any Holder fails to accept the Offer as to its Pro Rata Fraction, the other Holders shall, among them, have the right to purchase up to the balance of the Offered Shares not so purchased. Such right of oversubscription may be exercised by a Holder by accepting the Offer as to more than its Pro Rata Fraction. If, as a result thereof, such oversubscriptions exceed the total number of Offered Shares available in respect of such oversubscription privilege, the oversubscribing Holders shall be cut back with respect to their oversubscriptions on a pro rata basis in accordance with their respective Pro Rata Fractions or as they may otherwise agree among themselves. If a Holder desires to purchase all or any portion of the Offered Shares, said Holder shall communicate in writing its election to purchase to the Seller and the Company, which communication shall state the number of Offered Shares said Holder desires to purchase and shall be given to the Seller in accordance with Section 5.4 below within thirty (30) days of the date the Offer was made. Such communication shall, when taken in conjunction with the Offer, be deemed to constitute a valid, legally binding and enforceable agreement for the sale and purchase of such Offered Shares (subject to the aforesaid limitations as to a Holder's right to purchase more than its Pro Rata Fraction) and on the terms of the Offer. Sales of the Offered Shares to be sold to purchasing Holders pursuant to this Section 3.5(c) shall be made at the offices of the Company on the later of (i) the 45th day following the date the Offer was made (or if such later of (i) the 45th day is not a Business Day, then on the next succeeding Business Day) and (ii) the third Business Day following receipt of all material governmental or other consents in connection with such sale. Such sales shall be effected by the Seller's 11 delivery to each purchasing Holder of a certificate or certificates evidencing the Offered Shares to be purchased by it, duly endorsed for transfer to such purchasing Holder, against payment to the Seller of the purchase price therefor by such purchasing Holder. (d) If the Holders and the Company do not purchase in the aggregate all of the Offered Shares, the Offered Shares not so purchased may be sold by the Seller at any time within 90 days after the date the Offer was made, subject to the provisions of Section 3.6 hereof. Any such sale shall be to the Proposed Transferee, at the price and upon the other terms and conditions specified in the Offer. Any Offered Shares not sold within such 90-day period shall continue to be subject to the requirements of a prior offer pursuant to this Section 3.5. If Offered Shares are sold pursuant to this Section 3.5 to any purchaser who is not a party to this Agreement, the Offered Shares so sold shall no longer be subject to this Agreement. (e) The provisions of this Section 3.5 shall terminate upon the earlier of: (i) a Qualified Public Offering and (ii) the time at which the Investor Stockholders and the other Holders own less than 20% of the Common Stock (on an as converted basis) that the Investor Stockholders owned as of the Closing.

The parties acknowledge and agree that any Transfer described in the last sentence of Sections 3.3(a) and 3.4 (a) shall not be subject to the terms of this Section. (b) Each Investor Stockholder wishing to so participate in any sale under this Section 3.6 shall notify the Tag-Along Seller in writing of such intention within twenty (20) days after the date of their receipt of the Offer.
