2.     Agreement Among the Company and the Holders.

2.1     Right of First Refusal.

(a)     Grant. Subject to the terms of Section 3 below, each Holder hereby unconditionally and irrevocably grants to the Company a Right of First Refusal to purchase all or any portion of Transfer Stock that such Holder may propose to transfer in a Proposed Holder

Transfer, at the same price and on the same terms and conditions as those offered to the Prospective Transferee.

(b)     Notice. Each Holder proposing to make a Proposed Holder Transfer must deliver a Proposed Transfer Notice to the Company and each Holder not later than thirty (30) days prior to the consummation of such Proposed Holder Transfer. Such Proposed Transfer Notice shall contain the material terms and conditions (including price and form of consideration) of the Proposed Holder Transfer and the identity of the Prospective Transferee and the intended date of the Proposed Holder Transfer. To exercise its Right of First Refusal under this Section 2, the Company must deliver a Company Notice to the selling Holder within ten (10) days after delivery of the Proposed Transfer Notice. In the event of a conflict between this Agreement and any other agreement that may have been entered into by a Holder with the Company that contains a preexisting right of first refusal, the Company and the Holder 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 Subsection 2.1(a) and this Subsection 2.1(b).

(c)     Grant of Secondary Refusal Right to Holders. Subject to the terms of Section 3 below, each Holder hereby unconditionally and irrevocably grants to the other Holders a Secondary Refusal Right to purchase all or any portion of the Transfer Stock not purchased by the Company pursuant to Subsection 2.1(b), as provided in this Subsection 2.1(c). If the Company does not intend to exercise its Right of First Refusal with respect to all Transfer Stock subject to a Proposed Holder Transfer, the Company must deliver a Secondary Notice to the selling Holder and to each Holder to that effect no later than ten (10) days after the selling Holder delivers the Proposed Transfer Notice to the Company. To exercise its Secondary Refusal Right, a Holder must deliver an Exercise Notice to the selling Holder and the Company within ten (10) days after the Holder’s receipt of the Secondary Notice.

(d)     Undersubscription of Transfer Stock. If the Right of First Refusal and the Secondary Refusal Right have been exercised by the Company and the Holders with respect to some but not all of the Transfer Stock by the end of the ten (10)-day period specified in the last sentence of Subsection 2.1(c)) (the “Holder Notice Period”), then the Company shall, immediately after the expiration of the Holder Notice Period, send written notice (the “Company Undersubscription Notice”) to those Holders who fully exercised their Secondary Refusal Right within the Holder Notice Period (the “Exercising Holders”). Each Exercising Holder shall, subject to the provisions of this Subsection 2.1(d), 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. To exercise such option, an Exercising Holder must deliver an Undersubscription Notice to the selling Holder and the Company within ten (10) days after the expiration of the Holder Notice Period. In the event there are two or more such Exercising Holders that choose to exercise the last-mentioned option for a total number of remaining shares in excess of the number available, the remaining shares available for purchase under this Subsection 2.1(d) shall be allocated to such Exercising Holders pro rata based on the number of shares of Transfer Stock such Exercising Holders have elected to purchase pursuant to the Secondary Refusal Right (without giving effect to any shares of Transfer Stock that any such Exercising Holder has elected to purchase pursuant to the Company Undersubscription Notice). If the options to purchase the remaining shares are exercised in full by the Exercising Holders, the Company shall immediately notify all of the Exercising Holders and the selling 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 and as set forth in the Company Notice. If the Company or any Holder cannot for any reason pay for the Transfer Stock in the same form of non-cash consideration, the Company or such Holder may pay the cash value equivalent thereof, as determined in good faith by the Company’s Board of Directors and as set forth in the Company Notice. The closing of the purchase of Transfer Stock by the Company and the Holders shall take place, and all payments from the Company and the Holders shall have been delivered to the selling Holder, by the later of (i) the date specified in the Proposed Transfer Notice as the intended date of the Proposed Holder Transfer and (ii) fifty (50) days after delivery of the Proposed Transfer Notice.

2.2     Effect of Failure to Comply.

(a)     Transfer Void; Equitable Relief. Any Proposed Holder 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 Holder becomes obligated to sell any Transfer Stock to the Company or any Holder under this Agreement and fails to deliver such Transfer Stock in accordance with the terms of this Agreement, the Company and/or such Holder may, at its option, in addition to all other remedies it may have, send to such Holder the purchase price for such Transfer Stock as is herein specified and transfer to the name of the Company or such Holder (or request that the Company effect such transfer in the name of an Holder) on the Company’s books any certificates, instruments, or book entry representing the Transfer Stock to be sold.

3.     Exempt Transfers.

3.1     Exempted Transfers. Notwithstanding the foregoing or anything to the contrary herein, the provisions of Subsection 2.1 shall not apply: (a) in the case of a Holder that is an entity, upon a transfer by such Holder to its shareholders, members, partners or other equity holders, (b) to a repurchase of Transfer Stock from a Holder by the Company at a price no greater than that originally paid by such 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 Holder that is a natural person, upon a transfer of Transfer Stock by such Holder made for bona fide estate planning purposes, either during his or her lifetime or on death by will or intestacy to his or her spouse, child (natural or adopted), or any other direct lineal descendant of such Holder (or his or her spouse) (all of the foregoing collectively referred to as “family members”), or any other person approved by the Board of Directors of the Company, 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 Holder or any such family members, (d) to a sale or transfer of less than 10,000 shares of Transfer Stock within thirty (30) days (unless such sale or transfer is part of a series of sales or transfers to a single purchaser), (e) to sales of Transfer Stock on a national securities exchange, (f) to the transfer of Transfer Stock as a result of foreclosure in a margin account or otherwise on such Transfer Stock, (g) to a gift or transfer of Transfer Stock to a 501(c)(3) or other charitable organization, or (h) to the sale or transfer of Transfer Stock at the direction of any regulatory agency with oversight of the Company or its Affiliates; provided that in the case of clause (a), (c) or (d), the Holder shall deliver prior written notice to the Holders 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 issuance, 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 Holder (but only with respect to the securities so transferred to the transferee), including the obligations of a Holder with respect to Proposed Holder Transfers of such Transfer Stock pursuant to Section 2; and provided, further, in the case of any transfer pursuant to clause (a) or (c) 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 to the public in an offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (a “Public Offering”).

3.3     Prohibited Transferees. Notwithstanding the foregoing, no 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, instrument or book entry representing shares of Transfer Stock held by the Holders or issued to any permitted transferee in connection with a transfer permitted by Subsection 3.1 hereof shall be endorsed with the following legend:

THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO, AND IN CERTAIN CASES PROHIBITED BY, THE TERMS AND CONDITIONS OF A CERTAIN RIGHT OF FIRST REFUSAL BY AND AMONG THE SHAREHOLDER, THE CORPORATION AND CERTAIN OTHER HOLDERS OF STOCK OF THE CORPORATION. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION.

Each Holder agrees that the Company may instruct its transfer agent to impose transfer restrictions on the shares notated with the legend referred to in this Section 4 above to enforce the provisions

Any amendment, modification, termination or waiver so effected shall be binding upon the Company, the Holders and all of their respective successors and permitted assigns whether or not such party, assignee or other shareholder entered into or approved such amendment, modification, termination or waiver.
