Any purported Transfer in violation of any provision of this Agreement shall be void and ineffectual and shall not operate to Transfer any interest or title to the purported Transferee. The Company shall not (i) transfer on its books any Common Stock that has been Transferred in violation of this Agreement or (ii) treat as the owner of such Common Stock, or accord the right to vote or pay dividends to, any such Transferee.

(b) Provided that the Transferee complies with the terms of Section 3, the restrictions contained in this Section 1 shall not apply to:

(i) any Transfer of Common Stock by a Common Holder to such Common Holder’s spouse, parents, siblings or lineal descendants (by blood, marriage or adoption);

(ii) any Transfer of Common Stock by a Common Holder to a trust, partnership, corporation, limited liability company or other similar entity solely for the benefit of such Common Holder or such Common Holder’s spouse, parents, siblings or lineal descendants (by blood, marriage or adoption);

(iii) any Transfer of Common Stock by a Common Holder, upon such Common Holder’s death, to the executors, administrators, testamentary trustees, legatees or beneficiaries of such Common Holder; or

(iv) any Transfer of Common Stock by a Common Holder to the Company pursuant to a stock restriction agreement or other agreement under which the Company has the right to repurchase such Common Stock upon the occurrence of certain events, including termination of employment by or service to the Company or any subsidiary of the Company;

provided that in each of clauses (i) and (ii) the Transferee grants to a Common Holder an irrevocable proxy coupled with an interest to vote all of the Common Stock so Transferred. The exemptions set forth in Section 1.1(b) from the Transfer restrictions contained in this Section 1 shall also be available to any permitted Transferee of a Common Holder as if such permitted Transferee was a Common Holder for the purposes of such Section 1.1(b).

(c) Notwithstanding any other terms of this Agreement, shares of Common Stock acquired pursuant to that certain Common Stock Purchase Agreement dated on or about the date hereof (the “Selected Common Stock”) shall not be subject to any restrictions under this Agreement, and the holders of Selected Common Stock shall not be Common Holders hereunder as a result of the ownership of shares of Selected Common Stock.

1.2 Notice of Proposed Transfer. Except as otherwise permitted in Section 1.1(b) of this Agreement, before a Common Holder or permitted Transferee of a Common Holder (each, a “Seller”) may effect any Transfer of Common Stock, the Seller shall deliver to the Company and the Investors a written notice signed by the Seller (the “Seller’s Notice”) stating (a) the Seller’s bona fide intention to Transfer such Common Stock; (b) the name and address of each proposed Transferee; (c) the number of shares of the Common Stock to be Transferred to each Transferee (the “Transfer Shares”); and (d) the bona fide cash price or other consideration for which the Seller proposes to Transfer such Common Stock (the “Offered Price”). A copy of any written offer, if available, shall be attached to the Seller’s Notice. If a copy of a written offer is not available, a statement of the terms of the offer and any material facts shall be attached to the Seller’s Notice. Upon the request of the Company or an Investor, the Seller will promptly furnish such information to the Company and to the Investor as may be reasonably requested to establish that the offer and proposed Transferee are bona fide.

1.3 Right of First Refusal.

(a) Upon receipt of a Seller’s Notice, the Company shall have the irrevocable and exclusive option to purchase all or any portion of the Transfer Shares. The Company shall deliver a written notice (the “Company Notice”) to the Seller and each Investor of its election to purchase all or any part of such Transfer Shares within thirty (30) days of the receipt of the Seller’s Notice. The delivery of the Company Notice under this Section shall constitute an irrevocable commitment to purchase such Transfer Shares unless there is a legal prohibition as to a party’s consummation thereof.

(b) To the extent that the Company does not elect to purchase all of the Transfer Shares or fails to deliver the Company Notice within the applicable period, each Investor shall have the irrevocable and exclusive option to purchase up to that number of the Transfer Shares equal to the product of (i) the number of Transfer Shares not elected to be purchased by the Company multiplied by (ii) a fraction (the “Proportionate Share”), the numerator of which shall be the number of shares of Senior Preferred Stock and Selected Common Stock owned by such Investor and the denominator of which shall be the number of shares of Senior Preferred Stock and Selected Common Stock owned by all of the Investors. Within thirty (30) days after delivery of the Company Notice, each Investor desiring to participate in the purchase of the Transfer Shares shall deliver a written notice to the Seller, the Company and each other Investor of its election to purchase such Transfer Shares. To the extent

any Investor does not elect to purchase its full Proportionate Share of such remaining Transfer Shares or fails to deliver a notice within the applicable period, each Investor that has elected to purchase its full Proportionate Share shall be entitled, by delivering written notice to the Seller within forty-five (45) days following the delivery of the Company Notice, to purchase up to all of the remaining Transfer Shares. If there is an oversubscription, the oversubscribed amount shall be allocated among the fully electing Investors pro rata based on the number of shares of Senior Preferred Stock owned by each of them. The delivery of a notice of election under this Section shall constitute an irrevocable commitment to purchase such Transfer Shares (unless there is a legal prohibition as to a party’s consummation thereof).

(c) For the purposes of calculating an Investor’s Proportionate Share pursuant to Section 1.3(b), all Common Stock and Senior Preferred Stock held by an Investor and its partners, officers, employees and affiliates shall be aggregated and such persons may allocate such Proportionate Share in any manner among them.

1.4 Closing of Right of First Refusal. The purchase price for the Transferred Shares to be purchased by the Company or an Investor shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the non cash consideration shall be determined by the Board of Directors of the Company in good faith, which determination shall be binding upon the Company, each Stockholder, and the Seller, absent fraud or material error. Payment of the purchase price shall be made within five (5) days after expiration of all applicable periods set forth above. Payment of the purchase price shall be made, at the option of the Company or the exercising Investor, as the case may be, (a) in cash (by wire transfer or check), (b) by cancellation of all or a portion of any outstanding indebtedness of the Seller to the Company or the Investor, as the case may be, or (c) by any combination of the foregoing. Upon delivery of the purchase price, the Seller shall have no further rights as a holder of the Transfer Shares, and the Seller shall immediately cause all certificate(s) evidencing such Transfer Shares to be surrendered for transfer to the Company or the purchasing Investor, as the case may be.

1.5 Seller’s Right To Transfer. If the Company and the Investors have not elected to purchase all of the Transfer Shares, then, subject to the Investors’ right of co-sale set forth in Section 1.6, the Seller may transfer the remaining Transfer Shares to any person named as a Transferee in the Seller’s Notice, at the Offered Price or a higher price, provided that such Transfer (a) is consummated within ninety (90) days after the expiration of all applicable periods set forth above in Section 1.3(b), (b) is on terms no more favorable than the terms proposed in the Seller’s Notice, and (c) is in accordance with all the terms of this Agreement. If the Transfer Shares are not so Transferred during such period, then the Seller may not Transfer any of such Transfer Shares without complying again in full with the provisions of this Agreement.

1.6 Right of Co-Sale. If all of the Transfer Shares proposed to be sold by a Seller are not purchased by the Company or the Investors as provided in Section 1.3, the Seller shall deliver a notice to each non-purchasing Investor informing it of the number of Transfer Shares not elected to be purchased by the purchasing Investors and the number of Transfer Shares still held by the Seller (the “Co-Sale Shares”) and proposed to be Transferred to the Transferee. Each such non-purchasing Investor shall have the right, exercisable upon written

notice to the Seller within five (5) days after the receipt of such notice from the Seller, to elect to sell all or any part of the Senior Preferred Stock, Common Stock, other capital stock of the Company or any securities convertible into, exchangeable for or exercisable for capital stock of the Company (collectively, “Stock”) held by such Investor with the Seller to the Transferee. The delivery of the notice of election under this Section shall constitute an irrevocable commitment to sell the indicated Stock unless there is a legal prohibition as to a party’s consummation hereof. The Seller shall use all commercially reasonable efforts to arrange for the sale to the Transferee of all Stock requested by such Investors to be sold in such Transfer; provided that if the Transferee is unwilling to purchase all such Stock, then the number of shares of Stock that may be sold by the Seller and each such Investor in such Transfer shall be reduced to the product obtained by multiplying (a) the aggregate number of shares of Stock that the Transferee is willing to acquire by (b) a fraction the numerator of which is the number of shares of Stock requested to be Transferred by the Seller in the Seller’s Notice or by such Investor in the notice delivered under this Section, as applicable, and the denominator of which is the combined number of shares of Stock of the Company so requested be Transferred by the Seller and all participating Investors. The Stock to be sold shall be transferred by the Seller and the participating Investors to the Transferee in consummation of the sale of the Stock pursuant to the terms and conditions specified in the Seller’s Notice, and after such transfer the Seller shall promptly remit to each participating Investor that portion of the sale proceeds to which such Investor is entitled by reason of its participation in such sale. To the extent that any prospective Transferee prohibits such assignment or otherwise refuses to purchase shares or other securities from any participating Investor, the Seller shall not sell to such prospective Transferee any Stock unless and until, simultaneously with such sale, the Seller shall have complied with Section 2.

1.7 Multiple Series or Classes of Stock. If the Transfer Shares consists of more than one series, class, or type of Stock, the Seller has the right to Transfer under this Agreement each such series, class, or type; provided that if, as to the right of co-sale set forth in Section 1.6 an Investor does not hold the requisite number of shares of such series, class, or type, and the proposed Transferee is not willing to purchase the series, class, or type of Stock held by such Investor, then such Investor shall have the put right set forth in Section 2.

1.8 Additional Transactions. The exercise or non-exercise of the rights of a Stockholder under this Agreement to participate in one or more sales of Stock made by the Seller shall not adversely affect their rights to participate in subsequent sales by a Seller.

SECTION 2. PUT RIGHT.

If a Seller Transfers any Stock in contravention of the Company’s and the Investors’ right of co-sale under Section 1.6 (a “Prohibited Transfer”), or if the proposed Transferee of Transfer Shares desires to purchase a class, series, or type of stock offered by the Seller and not held by an Investor, or is unwilling to purchase any Stock from an Investor, such Investor may, by delivery of written notice to such Seller (a “Put Notice”) within ten (10) days after the later of (a) the consummation of the Transfer pursuant to Section 1.6 or (b) the date on which an Investor becomes aware of the Prohibited Transfer or the terms of such Prohibited Transfer, require such Seller to purchase from the Investor, for cash or such other consideration as the Seller received in the Prohibited Transfer, a number of shares of Stock (of the same class or type as transferred in

the Prohibited Transfer if such Investor then owns Stock of such class or type; otherwise of Stock having as close to the same economic consequences of ownership as is possible) having a purchase price equal to the aggregate purchase price the Investor would have received in the closing of such Prohibited Transfer if such Investor had been able to exercise its right of co-sale with respect to such Prohibited Transfer. The closing of such sale to the Seller shall occur within thirty (30) days after the date of such Investor’s Put Notice to such Seller. If a Seller Transfers any Stock in contravention of the Company’s and the Investor’s right of co-sale undo this Section 1.6, the Seller shall reimburse each Investor exercising or attempting to exercise this put right for reasonable fees and expenses, including legal fees and expenses, incurred in connection with the exercise or the attempted exercise of such Investor’s rights under this Section 2.1.
