2. Agreement Among the Investors and the Key Holders.

2.1 Right of First Refusal.

(a) Grant. Subject to the terms of Section 3 below, each Key Holder hereby unconditionally and irrevocably grants to the Investors a Right of First Refusal to purchase all or any portion of Transfer Stock that such Key Holder may propose to transfer in a Proposed Transfer, at the same price and on the same terms and conditions as those offered to the Prospective Transferee.

(b) Notice. Each Key Holder proposing to make a Proposed Transfer must deliver a Proposed Transfer Notice to the Company and each Investor not later than fifteen (15) days prior to the consummation of such Proposed Transfer. Such Proposed Transfer Notice shall contain the material terms and conditions (including price and form of consideration) of the Proposed Transfer and the identity of the Prospective Transferee. To exercise its Right of First Refusal under this Section 2, an Investor (in such capacity, an “Exercising Investor”) must deliver an Election Notice to the selling Key Holder within fifteen (15) days after delivery of the Proposed Transfer Notice specifying the number of shares of Transfer Stock to be purchased by such Investor. In the event that the number of shares of Transfer Stock elected to be purchased by Exercising Investors is greater than the number of shares of Transfer Stock available for purchase through a Right of First Refusal, then the shares of Transfer Stock shall be allocated among the Exercising Investors on a pro rata basis (based on their relative number of shares of Capital Stock) or in such other proportion as the Exercising Investors may agree. In the event of a conflict between this Agreement and any other agreement that may have been entered into by a Stockholder with the Company that contains a preexisting right of first refusal, the Company and such Stockholder acknowledge and agree that the terms of this Agreement shall control and the preexisting right of first refusal shall be deemed satisfied by compliance with Section 2.1(a) and this Section 2.1(b).

(c) Undersubscription of Transfer Stock. If options to purchase have been exercised by the Investors with respect to some but not all of the Transfer Stock by the end of the 15-day period specified in the first sentence of Section 2.1(b)) (the “Election Notice Period”), then the Company shall, immediately after the expiration of the Election Notice Period, send written notice (the “Undersubscription Notice”) to those Exercising Investors who exercised their Right of First Refusal within the Election Notice Period. Each Exercising Investor shall, subject to the provisions of this Section 2.1(c), have an additional option to purchase all or any part of the balance of any such remaining unsubscribed shares of Transfer Stock on the terms and conditions set forth in the Proposed Transfer Notice (the “Undersubscription Option”). To exercise the Undersubscription Option, an Exercising Investor must deliver an Undersubscription Notice to the selling Key Holder and the Company within ten (10) days after the expiration of the Election Notice Period. In the event there are two or more such Exercising Investors that choose to exercise the Undersubscription Option for a total number of remaining shares in excess of the number available, the remaining shares available for purchase under this Section 2.1(c) shall be allocated to such Exercising Investors pro rata based on the number of shares of Transfer Stock such Exercising Investors have elected to purchase pursuant to the Right of First Refusal (without giving effect to any shares of Transfer Stock that any such Exercising Investor has elected to purchase pursuant to the Undersubscription Notice). If the options to purchase the remaining shares are exercised in full by the Exercising Investors, the Company shall immediately notify all of the Exercising Investors and the selling Key Holder of that fact.

(e) Consideration; Closing. If the consideration proposed to be paid for the Transfer Stock is in property, services or other non-cash consideration, the fair market value of the consideration shall be as determined in good faith by the Company’s Board of Directors. If any Exercising Investor cannot for any reason pay for the Transfer Stock in the same form of non-cash consideration, such Exercising Investor may pay the cash value equivalent thereof, as determined in good faith by the Company’s Board of Directors. The closing of the purchase of Transfer Stock by the Exercising Investors shall take place, and all payments from the Exercising Investors shall have been delivered to the selling Key Holder, by the later of (i) the date specified in the Proposed Transfer Notice as the intended date of the Proposed Transfer and (ii) thirty (30) days after delivery of the Proposed Transfer Notice.

2.2 Right of Co-Sale.

(a) Exercise of Right. If any Transfer Stock subject to a Proposed Transfer by a Key Holder is not purchased pursuant to Section 2.1 above and thereafter is to be sold to a Prospective Transferee, each respective Investor may elect to exercise its Right of Co-Sale and participate on a pro rata basis in the Proposed Transfer as set forth in Section 2.2(b) below and otherwise on the same terms and conditions specified in the Proposed Transfer Notice (provided that if an Investor wishes to sell Series D Preferred Stock, the price set forth in the Proposed Transfer Notice shall be appropriately adjusted based on the conversion ratio of the Series D Preferred Stock into Common Stock). Each Investor who desires to exercise its Right of Co-Sale must give such selling Key Holder written notice to that effect within ten (10) days after the deadline for delivery of the Proposed Transfer Notice described above, and upon giving such notice such Investor shall be deemed to have effectively exercised the Right of Co-Sale.

(b) Shares Includable. Each Investor who timely exercises such Investor’s Right of Co-Sale by delivering the written notice provided for above in Section 2.2(a) may include in the Proposed Transfer all or any part of such Investor’s Capital Stock equal to the product obtained by multiplying (i) the aggregate number of shares of Transfer Stock subject to the Proposed Transfer by (ii) a fraction, the numerator of which is the number of shares of Capital Stock owned by such Investor immediately before consummation of the Proposed Transfer and the denominator of which is the total number of shares of Capital Stock owned, in the aggregate, by all Investors immediately prior to the consummation of the Proposed Transfer, plus the number of shares of Transfer Stock held by such selling Key Holder. To the extent one or more of the Investors exercise such right of participation in accordance with the terms and conditions set forth herein, the number of shares of Transfer Stock that such selling Key Holder may sell in the Proposed Transfer shall be correspondingly reduced.

(c) Delivery of Certificates. Each Investor shall effect its participation in the Proposed Transfer by delivering to such transferring Key Holder, no later than fifteen (15) days after such Investor’s exercise of the Right of Co-Sale, one or more stock certificates, properly endorsed for transfer to the Prospective Transferee, representing:

(i) the number of shares of Common Stock that such Investor elects to include in the Proposed Transfer; or

(ii) the number of shares of Series D Preferred Stock that is at such time convertible into the number of shares of Common Stock that such Investor elects to include in the Proposed Transfer; provided, however, that if the Prospective Transferee objects to the delivery of Series D Preferred Stock in lieu of Common Stock, such Investor shall first convert the Series D Preferred Stock into Common Stock and deliver Common Stock as provided above. The Company agrees to make any such conversion concurrent with and contingent upon the actual transfer of such shares to the Prospective Transferee.

(d) Purchase Agreement. The parties hereby agree that the terms and conditions of any sale pursuant to this Section 2.2 will be memorialized in, and governed by, a written purchase and sale agreement with customary terms and provisions for such a transaction and the parties further covenant and agree to enter into such an agreement as a condition precedent to any sale or other transfer pursuant to this Section 2.2.

(e) Deliveries. Each stock certificate an Investor delivers to such selling Key Holder pursuant to Section 2.2(c) above will be transferred to the Prospective Transferee against payment therefor in consummation of the sale of the Transfer Stock pursuant to the terms and conditions specified in the Proposed Transfer Notice and the purchase and sale agreement, and such selling Key Holder shall concurrently therewith remit or direct payment to each Investor the portion of the sale proceeds to which such Investor is entitled by reason of its participation in such sale. If any Prospective Transferee or Transferees refuse(s) to purchase securities subject to the Right of Co-Sale from any Investor exercising its Right of Co-Sale hereunder, such Key Holder may not sell any Transfer Stock to such Prospective Transferee or Transferees unless and until, simultaneously with such sale, such Key Holder purchases all securities subject to the Right of Co-Sale from such Investor on the same terms and conditions (including the proposed purchase price) as set forth in the Proposed Transfer Notice.

(f) Additional Compliance. If any Proposed Transfer is not consummated within sixty (60) days after receipt of the Proposed Transfer Notice by the Company, the Stockholder proposing the Proposed Transfer may not sell any Transfer Stock unless they first comply in full with each provision of this Section 2. The exercise or election not to exercise any right by any Stockholder hereunder shall not adversely affect its right to participate in any other sales of Transfer Stock subject to this Section 2.2.

2.3 Effect of Failure to Comply.

(a) Transfer Void; Equitable Relief. Any Proposed Transfer not made in compliance with the requirements of this Agreement shall be null and void ab initio, shall not be recorded on the books of the Company or its transfer agent and shall not be recognized by the Company. Each party hereto acknowledges and agrees that any breach of this Agreement would result in substantial harm to the other parties hereto for which monetary damages alone could not adequately compensate. Therefore, the parties hereto unconditionally and irrevocably agree that any non-breaching party hereto shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity (including, without limitation, seeking specific performance or the rescission of purchases, sales and other transfers of Transfer Stock not made in strict compliance with this Agreement).

(b) Violation of First Refusal Right. If any Key Holder becomes obligated to sell any Transfer Stock to any Investor under this Agreement and fails to deliver such Transfer Stock in accordance with the terms of this Agreement, the Investor may, at its option, in addition to all other remedies it may have, send to such Key Holder the purchase price for such Transfer Stock as is herein specified and transfer to the name of such Investor (or request that the Company effect such transfer in the name of such Investor) on the Company’s books the certificate or certificates representing the Transfer Stock to be sold.

(c) Violation of Co-Sale Right. If Key Holder purports to sell any Transfer Stock in contravention of the Right of Co-Sale (a “Prohibited Transfer”), each Investor who desires to exercise its Right of Co-Sale under Section 2.2 may, in addition to such remedies as may be available by law, in equity or hereunder, require such Key Holder to purchase from such Investor the type and number of shares of Capital Stock that such Investor would have been entitled to sell to the Prospective Transferee under Section 2.2 had the Prohibited Transfer been effected pursuant to and in compliance with the terms of Section 2.2. The sale will be made on the same terms and subject to the same conditions as would have applied had the Key Holder not made the Prohibited Transfer, except that the sale (including, without limitation, the delivery of the purchase price) must be made within ninety (90) days after the Investor learns of the Prohibited Transfer, as opposed to the timeframe proscribed in Section 2.2. Such Key Holder shall also reimburse each Investor for any and all reasonable and documented out-of-pocket fees and expenses, including reasonable legal fees and expenses, incurred pursuant to the exercise or the attempted exercise of the Investor’s rights under Section 2.2.

3. Exempt Transfers.

3.1 Exempted Transfers. Notwithstanding the foregoing or anything to the contrary herein, the provisions of Sections 2.1 and 2.2 shall not apply: (a) in the case of a Key Holder that is an entity, upon a transfer by such Key Holder to its stockholders, members, managers, managing members, partners or other equity holders, (b) to a repurchase of Transfer Stock from a Key Holder by the Company at a price no greater than that originally paid by such Key Holder for such Transfer Stock and pursuant to an agreement containing vesting and/or repurchase provisions approved by a majority of the Company’s Board of Directors, (c) in the case of a Key Holder that is a natural person, upon a transfer of Transfer Stock by such Key Holder made for bona fide estate planning purposes, either during his or her lifetime or on death by will or intestacy to an Immediate Family Member, or any other direct lineal descendant of such Key Holder (or his or her spouse) (all of the foregoing collectively referred to as “family members”), or any other person approved by the Company’s Board of Directors or any custodian or trustee of any trust, partnership or limited liability company for the benefit of, or the ownership interests of which are owned wholly by, such Key Holder or any such family members or (d) solely with respect each Investor, to an Affiliate of such Investor; provided that in the case of clauses (a) and (c), the Key Holder shall deliver prior written notice to the Investors of such pledge, gift or transfer and such shares of Transfer Stock shall at all times remain subject to the terms and restrictions set forth in this Agreement and such transferee shall, as a condition to such transfer, deliver a counterpart signature page to this Agreement as confirmation that such transferee shall be bound by all the terms and conditions of this Agreement as a Key Holder (but only with respect to the securities so transferred to the transferee), including the obligations of a Key Holder with respect to Proposed Transfers of such Transfer Stock pursuant to Section 2; and provided, further, in the case of any transfer pursuant to clauses (a), (c) and (d) above, that such transfer is made pursuant to a transaction in which there is no consideration actually paid for such transfer.

3.2 Exempted Offerings. Notwithstanding the foregoing or anything to the contrary herein, the provisions of Section 2 shall not apply to the sale of any Transfer Stock (a) to the public in an offering pursuant to an effective registration statement under the Securities Act of 1933, as amended or (b) pursuant to a Deemed Liquidation Event (as defined in the Series D Certificate of Designation).

3.3 Prohibited Transferees. Notwithstanding the foregoing, no Key Holder shall transfer any Transfer Stock to (a) any entity which, in the determination of the Company’s Board of Directors, directly or indirectly competes with the Company or (b) any customer, distributor or supplier of the Company, if the Company’s Board of Directors should determine that such transfer would result in such customer, distributor or supplier receiving information that would place the Company at a competitive disadvantage with respect to such customer, distributor or supplier.

4. Legend. Each certificate representing shares of Transfer Stock held by the Stockholders or issued to any permitted transferee in connection with a transfer permitted by Section 3.1 hereof shall be endorsed with the following legend:
