3. RIGHT OF PARTICIPATION.

3.1. Right of Participation.

3.1.1. Offer. Not fewer than ten business days prior to the consummation of an Issuance, a notice (the “Participation Notice”) shall be furnished by the Issuer to each holder of Participation Shares (the “Participation Offerees”). The Participation Notice shall include:

(i) the principal terms and conditions of the proposed Issuance, including (i) the amount, kind and terms of the Subject Securities to be included in the Issuance, (ii) the number of Equivalent Shares represented by such Subject Securities (if applicable), (iii) the percentage of the total Purchase Price Value of Shares outstanding as of immediately prior to giving effect to such Issuance which the Purchase Price Value of Participation Shares held by such Participation Offeree constitutes (the “Participation Portion”), (iv) the maximum and minimum price (including if applicable, the maximum and minimum Price Per Equivalent Share) per unit of the Subject Securities, including a description of any non-cash consideration sufficiently detailed to permit valuation thereof, (v) the proposed manner of disposition, (vi) the name and address of the Person to whom the Subject Securities will be issued (the “Prospective Subscriber”) and (vii) if known, the proposed Issuance date; and

-4-

(ii) an offer by the Issuer to issue, at the option of each Participation Offeree, to such Participation Offeree such portion of the Subject Securities to be included in the Issuance as may be requested by such Participation Offeree (not to exceed the Participation Portion of the total amount of Subject Securities to be included in the Issuance), on the same terms and conditions, with respect to each unit of Subject Securities issued to the Participation Offerees, as each of the Prospective Subscribers shall be issued units of Subject Securities.

3.1.2. Exercise.

(i) General. Each Participation Offeree desiring to accept the offer contained in the Participation Notice shall accept such offer by furnishing a written notice of such acceptance to the Issuer within eight business days after the date of delivery of the Participation Notice specifying the amount of Subject Securities (not in any event to exceed the Participation Portion of the total amount of Subject Securities to be included in the Issuance) which such Participation Offeree desires to be issued (each a “Participating Buyer”). Each Participation Offeree who does not accept such offer in compliance with the above requirements, including the applicable time periods, shall be deemed to have waived all of such holder’s rights to participate in such Issuance, and the Issuer shall thereafter be free to issue Subject Securities in such Issuance to the Prospective Subscriber and any Participating Buyers, at a price no less than the minimum price set forth in the Participation Notice and on other principal terms not substantially more favorable to the Prospective Subscriber than those set forth in the Participation Notice, without any further obligation to such non-accepting Participation Offerees pursuant to Section 3. If, prior to consummation, the terms of such proposed Issuance shall change with the result that the price shall be less than the minimum price set forth in the Participation Notice or the other principal terms shall be substantially more favorable to the Prospective Subscriber than those set forth in the Participation Notice, it shall be necessary for a separate Participation Notice to be furnished, and the terms and provisions of this Section 3.1 separately complied with, in order to consummate such Issuance pursuant to this Section 3.1; provided, however, that in such case of a separate Participation Notice, the applicable period to which reference is made in Section 3.1.1 and in the first sentence of this Section 3.1.2(i) shall be three business days and two business days, respectively.

(ii) Irrevocable Acceptance. The acceptance of each Participating Buyer shall be irrevocable except as hereinafter provided, and each such Participating Buyer shall be bound and obligated to acquire in the Issuance on the same terms and conditions, with respect to each unit of Subject Securities issued, as the Prospective Subscriber, such amount of Subject Securities as such Participating Buyer shall have specified in such Participating Buyer’s written commitment.

(iii) Time Limitation. If at the end of the 180th day after the date of the effectiveness of the Participation Notice the Issuer has not completed the Issuance, each Participating Buyer shall be released from such holder’s obligations under the written commitment, the Participation Notice shall be null and void, and it shall be necessary for a separate Participation

-5-

Notice to be furnished, and the terms and provisions of this Section 3.1 separately complied with, in order to consummate such Issuance pursuant to this Section 3.1; provided, however, that in such case of a separate Participation Notice on substantially the same terms and conditions, the applicable period to which reference is made in Section 3.1.1 and in the first sentence of Section 3.1.2(i) shall be three business days and two business days, respectively.

3.1.3. Other Securities. The Issuer may condition the participation of the Participation Offerees in an Issuance upon the purchase by such Participation Offerees of any securities (including debt securities) other than Subject Securities (“Other Securities”) in the event that the participation of the Prospective Subscriber in such Issuance is so conditioned. In such case, each Participating Buyer shall acquire in the Issuance, together with the Subject Securities to be acquired by it, Other Securities in the same proportion to the Subject Securities to be acquired by it as the proportion of Other Securities to Subject Securities being acquired by the Prospective Subscriber in the Issuance, on the same terms and conditions, as to each unit of Subject Securities and Other Securities issued to the Participating Buyers, as the Prospective Subscriber shall be issued units of Subject Securities and Other Securities.

3.1.4. Certain Legal Requirements. In the event that the participation in the Issuance by a Participation Offeree as a Participating Buyer would require under applicable law (i) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities where such registration or qualification is not otherwise required for the Issuance or (ii) the provision to any participant in the Sale of any specified information regarding the Company or any of its subsidiaries or the securities that is not otherwise required to be provided for the Issuance, such Participation Offeree shall not have the right to participate in the Issuance. Without limiting the generality of the foregoing, it is understood and agreed that neither the Company nor the Issuer shall be under any obligation to effect a registration of such securities under the Securities Act or similar state statutes.

3.1.5. Further Assurances. Each Participating Buyer shall take or cause to be taken all such reasonable actions as may be necessary or reasonably desirable in order expeditiously to consummate each Issuance pursuant to this Section 3.1 and any related transactions, including executing, acknowledging and delivering consents, assignments, waivers and other documents or instruments; filing applications, reports, returns, filings and other documents or instruments with governmental authorities; and otherwise cooperating with the Issuer and the Prospective Subscriber. Without limiting the generality of the foregoing, each such Participating Buyer agrees to execute and deliver such subscription and other agreements specified by the Issuer to which the Prospective Subscriber will be party.

3.1.6. Expenses. All costs and expenses incurred by the Issuer in connection with any proposed Issuance of Subject Securities (whether or not consummated), including all attorney’s fees and charges, all accounting fees and charges and all finders, brokerage or investment banking fees, charges or commissions, shall be paid by the Company or the Issuer. The reasonable fees and charges of a single legal counsel for each Investor Group in connection with such proposed Issuance of Subject Securities (whether or not consummated) shall be paid by the Company or the

-6-

Issuer. Any other costs and expenses incurred by or on behalf of any holder of Shares in connection with such proposed Issuance of Subject Securities (whether or not consummated) shall be borne by such holder.

3.1.7. Closing. The closing of an Issuance pursuant to Section 3.1 shall take place on (i) the proposed date of Issuance, if any, set forth in the Participation Notice (provided, that consummation of any Transfer may be extended beyond such date to the extent necessary to obtain any applicable governmental approval or other required approval or to satisfy other conditions), (ii) if no proposed Transfer date was required to be specified in the Participation Notice, at such time as the Issuer shall specify by notice to each Participating Buyer (provided, that such closing with respect to a Participating Buyer shall not be prior to the date that is ten business days after the Company issues the applicable Participation Notice without the consent of such Participating Buyer) and (iii) at such place as the Issuer shall specify by notice to each Participating Buyer. At the closing of any Issuance under this Section 3.1.7, each Participating Buyer shall be delivered the notes, certificates or other instruments evidencing the Subject Securities (and, if applicable, Other Securities) to be issued to such Participating Buyer, registered in the name of such Participating Buyer or such holder’s designated nominee, free and clear of any liens or encumbrances, with any transfer tax stamps affixed, against delivery by such Participating Buyer of the applicable consideration.

3.2. Post-Issuance Notice. Notwithstanding the requirements of Section 3.1, the Issuer may proceed with any Issuance prior to having complied with the provisions of Section 3.1; provided, that the Issuer shall:

(i) provide to each holder of Shares who would have been a Participation Offeree in connection with such Issuance (i) prompt notice of such Issuance and (ii) the Participation Notice described in Section 3.1.1 in which the actual price per unit of Subject Securities (and, if applicable, actual Price Per Equivalent Share) shall be set forth;

(ii) offer to issue to such holder of Shares such number of securities of the type issued in the Issuance as may be requested by such holder of Shares (not to exceed the Participation Portion that such holder of Shares would have been entitled to pursuant to Section 3.1 multiplied by the sum of (a) the number of Subject Securities included in the Issuance and (b) the aggregate number of shares issued pursuant to this Section 3.2 with respect to such Issuance) on the same economic terms and conditions with respect to such securities as the subscribers in the Issuance received; and

(iii) keep such offer open for a period of ten business days, during which period, each such holder may accept such offer by sending a written acceptance to the Issuer committing to purchase an amount of such securities (not in any event to exceed the Participation Portion that such holder would have been entitled to pursuant to Section 3.1 multiplied by the sum of (a) the number of Subject Securities included in such issuance and (b) the aggregate number of shares issued pursuant to this Section 3.2 with respect to such Issuance).

-7-

3.5. Acquired Shares. Any Subject Securities constituting Stock acquired by any holder of Participation Shares pursuant to this Section 3 shall be deemed for all purposes hereof to be Shares hereunder.

(e) if applicable, in compliance with Section 6.

Except as required by Section 4.1.5(c), any Shares so Transferred to a Person other than a Stockholder or a Permitted Transferee shall conclusively be deemed thereafter not to be Shares under this Agreement.

4.3. Restrictions on Transfers to Strategic Investors. In addition to any other provision of this Agreement, no holder of Shares shall Transfer any Shares pursuant to Sections 4.1.1, 4.1.3 or 4.1.5 of this Agreement to a Strategic Investor without the approval of the holders of a majority of

the Common Stock on an As Converted Basis. If any Prospective Selling Stockholder proposes to Transfer any Shares pursuant to Section 4.1.1, 4.1.3 or 4.1.5 to any Prospective Buyer, the Prospective Selling Stockholder shall furnish a written notice (which notice may be the same notice as the Tag Along Notice, if any, delivered pursuant to Section 5.1 or the Sale Notice, if any, delivered pursuant to Section 5.4, in each case so long as such notice includes all of the information required by the next sentence) to the Company and each other Investor at least ten business days prior to such proposed Transfer. Such notice shall set forth the principal terms of the proposed Transfer, including (i) the number and class of the Shares to be Transferred, (ii) the per share purchase price or the formula by which such price is to be determined and (iii) the name and address of the Prospective Buyer. If the Prospective Buyer (or an Affiliate thereof) has previously been determined by the holders of a majority of the Common Stock on an As Converted Basis to be a Strategic Investor, or is presumed to be a Strategic Investor pursuant to the definition thereof, and such determination or presumption has not been reversed by written notice to all holders of Shares, the Prospective Selling Stockholder shall not Transfer any Shares to such Prospective Buyer without the written approval of the holders of a majority of the Common Stock on an As Converted Basis. If the Prospective Buyer (or an Affiliate thereof) has not previously been determined by the holders of a majority of the Common Stock on an As Converted Basis to be a Strategic Investor, or is not presumed to be a Strategic Investor pursuant to the definition thereof, the Prospective Selling Stockholder may Transfer Shares to such Prospective Buyer unless, within eight business days after the date of delivery of the notice required by the second preceding sentence, the holders of a majority of the Common Stock on an As Converted Basis deliver written notice to the Prospective Selling Stockholder that such Prospective Buyer has been designated a Strategic Investor. If, within such time period, a notice designating such Prospective Buyer a Strategic Investor is delivered, then the Prospective Selling Stockholder shall not Transfer any Shares to such Prospective Buyer. In the event any proposed Transfer to a Strategic Investor is approved in accordance with the foregoing, such approval shall also apply to Transfers made to such Prospective Buyer by any Tag Along Sellers. Notwithstanding anything in this Agreement to the contrary, the restrictions in this Section 4.3 shall not apply to any Transfers (i) to the Company or any of its subsidiaries, (ii) to any Investor, (iii) to any Affiliated Fund of any Investor, (iv) pursuant to Rule 144 effected as “brokers’ transactions” (as defined in Rule 144); or (v) pursuant to an underwritten Public Offering or, following the Initial Public Offering, pursuant to Rule 144 directly to a “market maker” (as defined in Rule 144) or pursuant to a block sale to a financial institution in the ordinary course of its trading business, in each case of this clause (v) in which, to the knowledge of the Prospective Selling Stockholder (after reasonable due inquiry), the underwriter(s), market maker(s) or block sale purchaser(s) are not acquiring such Shares for the intended purpose of reselling such Shares to any Person that, after giving effect to such resale, would own, directly or indirectly, more than five percent (5%) of then outstanding shares of the applicable class of Shares.

4.4. Impermissible Transfer. Any attempted Transfer of Shares not permitted under the terms of this Section 4 shall be null and void, and the Company shall not in any way give effect to any such impermissible Transfer.

4.5. Notice of Transfer. To the extent any Stockholder or Permitted Transferee shall Transfer any Shares pursuant to Section 4.1.1 or 4.1.5, such Stockholder or Permitted Transferee shall, within three business days following consummation of such Transfer, deliver notice thereof to the Company and each Investor.

-11-

4.6. Other Restrictions on Transfer. The restrictions on Transfer contained in this Agreement are in addition to any other restrictions on Transfer to which a Stockholder may be subject, including, without limitation, any restrictions on transfer contained in a restricted stock agreement, stock option agreement or stock subscription agreement.

4.7. Period. Each of the foregoing provisions of this Section 4 shall expire upon a Change of Control.

5. “TAG ALONG” AND “DRAG ALONG” RIGHTS AND RIGHT OF FIRST OFFER.

5.1. Tag Along. Subject to prior compliance with Section 5.4, if applicable, if any Prospective Selling Stockholder proposes to Sell any Shares to any Prospective Buyer(s) (including a First Offer Purchaser pursuant to Section 5.4) prior to the Initial Public Offering in a Transfer that is subject to Section 4.1.5:

5.1.1. Notice. The Prospective Selling Stockholder shall, prior to any such proposed Transfer, furnish a written notice (the “Tag Along Notice”) to each of the other holders of Shares (each, a “Tag Along Holder”). The Tag Along Notice shall include:

(a) the principal terms and conditions of the proposed Sale, including (i) the number and class of the Shares to be purchased from the Prospective Selling Stockholder, (ii) the fraction(s) expressed as a percentage, determined by dividing the number of Shares of each class to be purchased from the Prospective Selling Stockholder by the total number of Vested Shares of each such class held by the Prospective Selling Stockholder (for each class, the “Tag Along Sale Percentage”) (it being understood that the Company shall reasonably cooperate with the Prospective Selling Stockholder in respect of the determination of each applicable Tag Along Sale Percentage), (iii) the per share purchase price or the formula by which such price is to be determined and the payment terms, including a description of any non-cash consideration sufficiently detailed to permit valuation thereof, (iv) the name and address of each Prospective Buyer and (v) the proposed Transfer date; and

(b) an invitation to each Tag Along Holder to make an offer to include in the proposed Sale to the applicable Prospective Buyer(s) Vested Shares of the same class or classes being sold by the Prospective Selling Stockholder held by such Tag Along Holder (not in any event to exceed the Tag Along Sale Percentage of the total number of Vested Shares of the applicable class held by such Tag Along Holder), on the same terms and conditions (subject to Section 5.3.4 in the case of Options, Warrants and Convertible Securities and subject to Section 5.3.1 under all circumstances), with respect to each Share Sold, as the Prospective Selling Stockholder shall Sell each of its Shares. For purposes of this Section 5.1, the Common Stock will be treated as a single class and, subject to Section 5.3.4, all Options and Warrants will be treated as the same class of Shares for which they may be exercised.

-12-

5.1.2. Exercise. Within five (ten, if the proposed Transfer is not also the subject of a currently effective Sale Notice under Section 5.4) business days after the date of delivery of the Tag Along Notice (such date the “Tag Along Deadline”), each Tag Along Holder desiring to make an offer to include Vested Shares in the proposed Sale (each a “Participating Seller” and, together with the Prospective Selling Stockholder, collectively, the “Tag Along Sellers”) shall furnish a written notice (the “Tag Along Offer”) to the Prospective Selling Stockholder indicating the number of Vested Shares which such Participating Seller desires to have included in the proposed Sale (subject to the limitation set forth in Section 5.1.1(b)). Each Tag Along Holder who does not make a Tag Along Offer in compliance with the above requirements, including the time period, shall be deemed to have waived all of such holder’s rights with respect to such Sale, and the Tag Along Sellers shall thereafter be free to Sell to the Prospective Buyer, at a per share price no greater than the per share price set forth in the Tag Along Notice and on other principal terms and conditions which are not materially more favorable to the Tag Along Sellers than those set forth in the Tag Along Notice, without any further obligation to such non-accepting Tag Along Holder pursuant to this Section 5.1.

5.1.3. Irrevocable Offer. The offer of each Participating Seller contained in such holder’s Tag Along Offer shall be irrevocable, and, to the extent such offer is accepted, such Participating Seller shall be bound and obligated to Sell in the proposed Sale on the same terms and conditions, with respect to each Share Sold (subject to Section 5.3.4 in the case of Options, Warrants and Convertible Securities), as the Prospective Selling Stockholder, up to such number of Vested Shares as such Participating Seller shall have specified in such holder’s Tag Along Offer; provided, however, that if the principal terms of the proposed Sale change with the result that the per share price shall be less than the per share price set forth in the Tag Along Notice or the other principal terms and conditions shall be materially less favorable to the Tag Along Sellers than those set forth in the Tag Along Notice, the Prospective Seller shall provide written notice thereof to each Participating Seller and each Participating Seller shall be permitted to withdraw the offer contained in such holder’s Tag Along Offer by written notice to the Prospective Selling Stockholder and upon such withdrawal shall be released from such holder’s obligations thereunder.

5.1.4. Reduction of Shares Sold. The Prospective Selling Stockholder shall attempt to obtain the inclusion in the proposed Sale of the entire number of Vested Shares which each of the Tag Along Sellers requested to have included in the Sale (as evidenced in the case of the Prospective Selling Stockholder by the Tag Along Notice and in the case of each Participating Seller by such Participating Seller’s Tag Along Offer). In the event the Prospective Selling Stockholder shall be unable to obtain the inclusion of such entire number of Vested Shares in the proposed Sale, the number of Vested Shares to be sold in the proposed Sale shall be allocated among the Tag Along Sellers in proportion, as nearly as practicable, as follows:

(a) there shall be first allocated to each Tag Along Seller a number of Vested Shares equal to the lesser of (A) the number of Vested Shares offered (or proposed, in the case of the Prospective Selling Stockholder) to be included by such Tag Along Seller in the proposed Sale pursuant to this Section 5.1, and (B) a number of Vested Shares equal to such Tag Along Seller’s Pro Rata Portion; and

-13-

(b) the balance, if any, not allocated pursuant to clause (a) above shall be allocated to the Prospective Selling Stockholder, or in such other manner as the Prospective Selling Stockholder may otherwise agree (it being understood that no Tag Along Seller will be obligated to sell more Vested Shares than it offered to sell in the proposed Sale).

5.1.5. Additional Compliance. If prior to consummation, the terms of the proposed Sale shall change with the result that the per share price to be paid in such proposed Sale shall be greater than the per share price set forth in the Tag Along Notice or the other principal terms of such proposed Sale shall be materially more favorable to the Tag Along Sellers than those set forth in the Tag Along Notice, the Tag Along Notice shall be null and void, and it shall be necessary for a separate Tag Along Notice to be furnished, and the terms and provisions of this Section 5.1 separately complied with, in order to consummate such proposed Sale pursuant to this Section 5.1; provided, however, that in the case of such a separate Tag Along Notice, the period to which reference is made in Section 5.1.2 shall be three business days. In addition, if the Prospective Selling Stockholders have not completed the proposed Sale by the end of the 180th day after the date of delivery of: (i) if the proposed Transfer is also the subject of a currently effective Sale Notice under Section 5.4, such Sale Notice, and (ii) otherwise, the Tag Along Notice, each Participating Seller shall be released from such holder’s obligations under such holder’s Tag Along Offer, the Tag Along Notice shall be null and void, and it shall be necessary for a separate Tag Along Notice to be furnished, and the terms and provisions of this Section 5.1 separately complied with, in order to consummate such proposed Sale pursuant to this Section 5.1, unless the failure to complete such proposed Sale resulted from any failure by any Participating Seller to comply with the terms of this Section 5.

5.2. Drag Along. Each holder of Shares hereby agrees, if requested by the Requisite Drag Along Majority at any time prior to an Initial Public Offering, to Sell the same percentage (the “Drag Along Sale Percentage”) of each class of such Shares that is proposed to be sold by the Prospective Selling Stockholders to a Prospective Buyer in a Change of Control, in the manner and on the terms set forth in this Section 5.2; provided, however, that this Section 5.2 shall not apply to a Change of Control if such Prospective Buyer is a member of an Investor Group or an Affiliate of any such member. For purposes of this Section 5.2, subject to Section 5.3.4, all Options and Warrants will be the same class of Shares for which they may be exercised. All Shares to be sold pursuant to this Section 5.2 shall be included in determining whether or not a proposed transaction constitutes a Change of Control

5.2.1. Exercise. The Prospective Selling Stockholders shall furnish a written notice (the “Drag Along Notice”) to each other holder of Shares at least ten business days prior to the consummation of the Change of Control transaction. The Drag Along Notice shall set forth the principal terms and conditions of the proposed Sale, including (i) the number and class of Shares to be acquired from the Prospective Selling Stockholders, (ii) the Drag Along Sale Percentage for each class, (iii) the per share consideration to be received in the proposed Sale for each class, (iv) the name and address of the Prospective Buyer and (v) if known, the proposed Transfer date. If the Prospective Selling Stockholders consummate the proposed Sale to which reference is made in the Drag Along Notice, each other holder of Shares (each, a “Participating Seller,” and, together with

-14-

the Prospective Selling Stockholders, collectively, the “Drag Along Sellers”) shall: (i) be bound and obligated to Sell the Drag Along Sale Percentage of such holder’s Shares of each class in the proposed Sale on the same terms and conditions, with respect to each Share Sold (subject to Section 5.3.4 in the case of Options, Warrants and Convertible Securities) as the Prospective Selling Stockholders shall Sell each Share in the Sale (subject to Section 5.3.4 in the case of Options, Warrants and Convertible Securities and subject to Section 5.3.1 under all circumstances); and (ii) except as provided in Section 5.3.1, shall receive the same form and amount of consideration per Share to be received by the Prospective Selling Stockholders for the corresponding class of Shares (on an as converted basis, if applicable). Except as provided in Section 5.3.1, if any holders of Shares of any class are given an option as to the form and amount of consideration to be received (other than with respect to any roll-over option given to any or all members of Senior Management), all holders of Shares of such class will be given the same option. Unless otherwise agreed by each Drag Along Seller, any non-cash consideration shall be allocated among the Drag Along Sellers pro rata based upon the aggregate amount of consideration to be received by such Drag Along Sellers. If at the end of the 180th day after the date of delivery of the Drag Along Notice the Prospective Selling Stockholders have not completed the proposed Sale, the Drag Along Notice shall be null and void, each Participating Seller shall be released from such holder’s obligation under the Drag Along Notice and it shall be necessary for a separate Drag Along Notice to be furnished and the terms and provisions of this Section 5.2 separately complied with, in order to consummate such proposed Sale pursuant to this Section 5.2. The right of a holder of Unvested Shares to receive consideration for such Unvested Shares pursuant to this Section 5.2 shall be subject to the vesting and other terms of such Unvested Shares.

5.3. Miscellaneous. The following provisions shall be applied to any proposed Sale to which Section 5.1, 5.2 or 5.4 applies:

5.3.1. Certain Legal Requirements. In the event the consideration to be paid in exchange for Shares in a proposed Sale pursuant to Section 5.1 or Section 5.2 includes any securities, and the receipt thereof by a Participating Seller would require under applicable law (a) the registration or qualification of such securities or of any Person as a broker or dealer or agent with respect to such securities where such registration or qualification is not otherwise required for the Sale by the Prospective Selling Stockholders) or (b) the provision to any Tag Along Seller or Drag Along Seller of any specified information regarding the Company or any of its subsidiaries, such securities or the issuer thereof that is not otherwise required to be provided for the Sale by the Prospective Selling Stockholder(s), then such Participating Seller shall not have the right to Sell Shares in such proposed Sale. In such event, the Prospective Selling Stockholder(s) shall (i) in the case of a Sale pursuant to Section 5.1, have the right, but not the obligation, and (ii) in the case of a Sale pursuant to Section 5.2, have the obligation to cause to be paid to such Participating Seller in lieu thereof, against surrender of the Shares (in accordance with Section 5.3.6 hereof) which would have otherwise been Sold by such Participating Seller to the Prospective Buyer in the proposed Sale, an amount in cash equal to the Fair Market Value of such Shares as of the date such securities would have been issued in exchange for such Shares.

5.3.2. Further Assurances. Each Participating Seller and First Offer Purchaser shall take or cause to be taken all such actions as may be necessary or reasonably desirable in order expeditiously to consummate each Sale pursuant to Section 5.1, Section 5.2 or Section 5.4 and any related transactions, including executing, acknowledging and delivering consents, assignments, waivers and other documents or instruments; furnishing information and copies of documents; filing applications, reports, returns, filings and other documents or instruments with governmental authorities; and otherwise cooperating with the Prospective Selling Stockholders) and the Prospective Buyer; provided, however, that Participating Sellers shall be obligated to become liable in respect of any representations, warranties, covenants, indemnities or otherwise to the Prospective Buyer solely to the extent provided in the immediately following sentence. Without limiting the generality of the foregoing, each Participating Seller agrees to execute and deliver such agreements as may be reasonably specified by the Prospective Selling Stockholder(s) to which such Prospective Selling Stockholder(s) will also be party, including agreements to (a) (i) make individual representations, warranties, covenants and other agreements as to the unencumbered title to its Shares and the power, authority and legal right to Transfer such Shares and the absence of any Adverse Claim with respect to such Shares and (ii) be liable as to such representations, warranties, covenants and other agreements, in each case to the same extent (on a pro rata basis) as the Prospective Selling Stockholders), and (b) in the case of a Sale pursuant to Section 5.1 or Section 5.2, be liable (whether by purchase price adjustment, indemnity payments or otherwise) in respect of representations, warranties, covenants and agreements in respect of the Company and its subsidiaries; provided, however, that the aggregate amount of liability described in this clause (b) in connection with any Sale of Shares shall not exceed the lesser of (i) such Participating Seller’s pro rata portion of any such liability, to be determined in accordance with such Participating Seller’s portion of the aggregate proceeds to all Participating Sellers and Prospective Selling Stockholder(s) in connection with such Sale or (ii) the proceeds to such Participating Seller in connection with such Sale.

No holder of Shares nor any Affiliate of any such holder shall have any liability to any other holder of Shares or the Company arising from, relating to or in connection with the pursuit, consummation, postponement, abandonment or terms and conditions of any proposed Sale except to the extent such holder shall have failed to comply with the provisions of this Section 5.

5.3.4. Treatment of Options, Warrants and Convertible Securities. If any Participating Seller shall Sell Options, Warrants or Convertible Securities in any Sale pursuant to Section 5, such Participating Seller shall receive in exchange for such Options, Warrants or Convertible Securities consideration in the amount (if greater than zero) equal to the purchase price received by the Prospective Selling Stockholder(s) in such Sale for the number of shares of each class of Stock that would be issued upon exercise, conversion or exchange of such Options, Warrants or Convertible Securities less the exercise price, if any, of such Options, Warrants or Convertible Securities (to the extent exercisable, convertible or exchangeable at the time of such Sale), subject to reduction for any tax or other amounts required to be withheld under applicable law.

5.4.2. Exercise.

(a) Within ten business days after the date of delivery of the Sale Notice (the “Company Offer Deadline”), the Company may make an offer to purchase any number of the Subject Shares at the price set forth in the Sale Notice by furnishing a written notice (the “Company Offer Notice”) to the Prospective Selling Stockholder and each First Offer Holder of such offer specifying a number of Subject Shares offered to be purchased from the Prospective Selling Stockholder. In the event that the Company has not elected to purchase all of the Subject Shares, within ten business days after the date of delivery of the Company Offer Notice (the “First Offer Deadline”), each First Offer Holder may make an offer to purchase any number of the remaining Subject Shares at the price set forth in the Sale Notice by furnishing a written notice (the “First Offer Notice”) of such offer specifying a number of remaining Subject Shares offered to be purchased from the Prospective Selling Stockholder (each such Person delivering such notice, a “First Offer Purchaser”). The receipt of consideration by any Prospective Selling Stockholder selling Shares in payment for the transfer of such Shares pursuant to this Section 5.4.2 shall be deemed a representation and warranty by such Prospective Selling Stockholder that: (i) such Prospective Selling Stockholder has full right, title and interest in and to such Shares; (ii) such Prospective Selling Stockholder has all necessary power and authority and has taken all necessary action to sell such Shares as contemplated by this Section 5.4.2; and (iii) such Shares are free and clear of any and all liens or encumbrances.

(b) Each Person not furnishing a First Offer Notice that complies with the above requirements, including the applicable time periods, shall be deemed to have waived all of such Person’s rights to purchase such Shares under this Section 5.4.2 and the Prospective Selling Stockholder shall thereafter be free to Sell the Subject Shares to the Company, the First Offer Purchasers and/or any Prospective Buyer, at a per share purchase price no less than the price set forth in the Sale Notice, without any further obligation to such Person pursuant to this Section 5.4.

5.4.3. Irrevocable Offer. The offer of the Company contained in the Company Offer Notice and the offer of each First Offer Purchaser contained in a First Offer Notice shall be irrevocable, and, subject to Section 5.4.6 below, to the extent such offer is accepted, the Company and/or such First Offer Purchaser shall be bound and obligated to purchase the number of Subject Shares set forth in the Company Offer Notice or such First Offer Purchaser’s First Offer Notice, as applicable.

5.4.4. Acceptance of Offers. Within five business days after the First Offer Deadline, the Prospective Selling Stockholder shall inform the Company, if applicable, and each First Offer Purchaser, by written notice (the “Acceptance Notice”), of whether or not the Prospective Selling Stockholder will accept all (but not less than all) offers of the Company and/or the First Offer Purchasers. In the event the Prospective Selling Stockholder fails to furnish the Acceptance Notice within the specified time period, the Prospective Selling Stockholder shall be deemed to have decided not to Sell the Subject Shares to the Company and/or the First Offer Purchasers. If the Prospective Selling Stockholder decides not to Sell the Subject Shares to the Company and/or the First Offer Purchasers, each of the Company and/or each First Offer Purchaser shall be released from

-18-

its obligations under its irrevocable offer. Acceptance of such offers by the Prospective Selling Stockholder is without prejudice to the Prospective Selling Stockholder’s discretion under Section 5.3.3 to determine whether or not to consummate any Sale.

If at the end of the 180th day after the date of delivery of the Sale Notice, the Prospective Selling Stockholder, the Company, if applicable, and First Offer Purchasers or Prospective Buyer (if not a First Offer Purchaser), if any, have not completed the Sale of the Subject Shares (other than due to the failure of the Company or any First Offer Purchaser to perform its obligations under this Section 5.4), each of the Company and/or each First Offer Purchaser shall be released from its obligations under its irrevocable offer, the Sale Notice shall be null and void, and it shall be necessary for a separate Sale Notice to be furnished, and the terms and provisions of this Section 5.4 separately complied with, in order to consummate a Transfer of such Subject Shares; provided, however, that in the case of such a separate Sale Notice in which the classes of Subject Shares and the per share price are unchanged and the number of Subject Shares is substantially the same, the period to which reference is made in Section 5.4.2(a) shall be three business days.

5.4.6. Determination of the Number of Subject Shares to be Sold.

(a) In the event that the number of Shares offered to be purchased by the Company and the First Offer Purchasers is less than the number of Subject Shares, (i) the Prospective Selling Stockholder may accept the offers of the Company and the First Offer Purchasers and, at the option of the Prospective Selling Stockholder, sell any remaining Subject Shares which the First Offer Purchasers did not elect to purchase to one or more Prospective Buyers at a price per share that is no less than the price set forth in the Sale Notice or (ii) if a single Prospective Buyer or group of Prospective Buyers is unwilling to purchase less than all of the Subject Shares, the Prospective Selling Stockholder may Sell all (but not less than all) of the Subject Shares to such Prospective Buyer or group of Prospective Buyers at a price per share that is no less than the price set forth in the Sale Notice rather than Sell the Subject Shares to the Company and the First Offer Purchasers. Such sales, if any, to Prospective Buyer(s) other than the Company and the First Offer Purchasers in accordance with clause (a) above shall be consummated together with the sale to the Company and the First Offer Purchasers.

(b) In the event that the Prospective Selling Stockholder has accepted the offers of the First Offer Purchasers and the aggregate number of Subject Shares offered to be purchased by (and to be sold to) the First Offer Purchasers is equal to or exceeds the aggregate number of Subject Shares then available for purchase, the Subject Shares shall be sold to the First Offer Purchasers as follows:

(i) there shall be first allocated to each First Offer Purchaser a number of Shares of each applicable class equal to the lesser of (A) the number of Shares of such class offered to be purchased by such First Offer Purchaser pursuant such holder’s First Offer Notice, and (B) a number of Shares of such class equal to such First Offer Purchaser’s Pro Rata Portion; and

(ii) the balance, if any, not allocated pursuant to clause (i) above shall be allocated to those First Offer Purchasers which offered to purchase a number of Shares of the applicable class in excess of such Person’s Pro Rata Portion pro rata to each such First Offer Purchaser based upon the amount of such excess, or in such other manner as the First Offer Purchasers may otherwise agree.

In the event any holders of Shares exercise such holders’ rights under Section 5.1 to sell Shares in connection with a Sale to the Company and/or First Offer Purchasers pursuant to this Section 5.4, such Shares (as the case may be, reduced in accordance with Section 5.1.5) shall be deemed to be Subject Shares for purposes of this Section 5.4 and shall be allocated among the First Offer Purchasers in accordance with this Section 5.4.6.

5.5. Period. The provisions of this Section 5 shall expire as to any Share on the earlier of (a) a Change of Control or (b) the Initial Public Offering.
