1.                                      GENERAL RESTRICTIONS ON TRANSFER; PERMITTED TRANSFEREES

1.1                               General Restrictions on Transfer.

(a)                                 Each Shareholder understands and agrees that the Company Securities held by it on the date hereof have not been registered under the Securities Act and are restricted securities under the Securities Act.  No Shareholder shall Transfer any Company Securities (or solicit any offers in respect of any Transfer of any Company Securities), except in compliance with the Securities Act, any other applicable securities or “blue sky” laws and any restrictions on Transfer contained in this Agreement or any other provisions set forth in any other agreements or instruments pursuant to which such Company Securities were issued.  No Shareholder shall Transfer any Company Securities

16

if such Transfer would cause any class of Company Securities to be required to become subject to registration under the Exchange Act.

(b)                                 Each Shareholder hereby agrees that such Shareholder shall not Transfer any of its Company Securities at any time other than pursuant to a Transfer in accordance with Section 1, Section 2 and Section 3.  Any Transfer of Company Securities, other than according to the terms of this Agreement, shall be void and transfer no right, title or interest in or to any of such Company Securities to the purported transferee. The parties hereto acknowledge that the transfer restrictions contained herein are reasonable and in the best interests of the Company.

(c)                                  Except in connection with a Drag-Along Sale or a transaction that would constitute a Liquidity Event, no Shareholder shall Transfer any Company Securities to a Company Competitor.

(d)                                 Until the third anniversary of the date of this Agreement (the “Lock-Up Period”), each Existing Shareholder hereby agrees that such Existing Shareholder shall not Transfer any of its Company Securities (other than any Series C Shares, Series C-1 Shares, Series C-2 Shares and Series D Shares, except Series C Shares, Series C-1 Shares, Series C-2 Shares and Series D Shares held by Management Shareholders) at any time other than Transfers (i) to the Investors or Permitted Transferees, (ii) as a Participating Seller in a Tag-Along Sale, (iii) in a Drag-Along Sale, (iv) a transaction that would constitute a Liquidity Event.  Following the Lock-Up Period, a Shareholder may not transfer its Company Securities, except in accordance and compliance with this Section 1, Section 2 and Section 3.

(e)                                  Notwithstanding anything to the contrary herein (including in Section 1.1(d) and Section 2), Management Shareholders may only Transfer their Company Securities (i) to Permitted Transferees, (ii) as a Participating Seller in a Tag-Along Sale, (iii) in Drag-Along Sale, (iv) in a transaction that would constitute a Liquidity Event or (v) as provided in Section 1.1(f).

(f)                                   Following the Initial Public Offering, subject to Section 1.1(a) and applicable laws (including applicable securities laws), each Management Shareholder may Transfer Common Shares, but only to the extent that such Transfer would not result in the Relative Ownership Percentage of the Common Shares of such Management Shareholder immediately following the effective time of such Transfer (the “Determination Time”) being less than the Relative Ownership Percentage of the Common Shares owned by the Avista Investors immediately following the Determination Time.

(g)                                  Each Existing Shareholder agrees that, during the period of ninety (90) days (or, in the case of an underwritten offering, such lesser period as the managing underwriters may permit, it being understood that the Company shall request for the

17

benefit of the Existing Shareholders that such managing underwriter act in good faith in determining whether to permit a shorter period) following the effective date of a registration statement of the Company filed under the Securities Act in connection with an underwritten offering (and, in the case of the initial public offering of the Company’s securities, one hundred eighty (180) days), which periods may be extended upon the request of the managing underwriter, to the extent required by any rules of the Financial Industry Regulatory Authority, Inc. or any successor organization thereto, for an additional period of up to fifteen (15) days if the Company issues or proposes to issue an earnings or other public release within fifteen (15) days of the expiration of such lockup period (or, in the case of an underwritten offering, such lesser period as the managing underwriters may permit, it being understood that the Company shall request for the benefit of the Existing Shareholders that such managing underwriter act in good faith in determining whether to permit a shorter period), it shall not, if requested by such underwriter, sell or otherwise transfer or dispose of (other than to donees, Affiliates, partners or members who agree to be similarly bound) any Common Shares or any securities of the Company convertible into Common Shares held by it except Registrable Securities (as defined in that certain Second Amended and Restated Registration Rights Agreement dated as of March 24, 2017) included in such registration.  Each Shareholder further agrees to execute such agreements as may be reasonably requested by the underwriters in connection with such registration that are consistent with this Section 1.1(g) or that are necessary to give further effect thereto.

1.2                               Permitted Transferees.  Subject to Section 1.1, Transfers of Company Securities by any Shareholder to a Permitted Transferee shall be permitted and shall not be subject to the transfer restrictions in Section 2 (Right of First Refusal) or Section 3.1 (Tag-Along Rights), to the extent applicable, so long as such Permitted Transferee signs the Joinder Agreement or similar agreement whereby such transferee shall be subject to the terms and conditions of this Shareholders Agreement.  Each Shareholder must give prior written notice to the Company of any proposed Transfer to such Permitted Transferee, including the identity of such Permitted Transferee and such other documentation reasonably requested by the Company to ensure compliance with the terms of this Agreement.

1.3                               Legend.  At all times prior to an Initial Public Offering, in addition to any other legend that may be required, each certificate for Company Securities issued to any Shareholder shall bear a legend in substantially the following form with such changes as the Company determines advisable or necessary to qualify for notice, registration and other exemptions under “blue sky” laws:

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED WITHOUT REGISTRATION

18

UNDER THE SECURITIES ACT OR STATE SECURITIES LAWS OR AN OPINION OF COUNSEL, SATISFACTORY TO THE COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO THE TERMS AND CONDITIONS OF A SHAREHOLDERS AGREEMENT BY AND AMONG THE COMPANY AND THE HOLDERS SPECIFIED THEREIN, A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.  THE SALE, TRANSFER OR OTHER DISPOSITION OF THE SECURITIES IS SUBJECT TO THE TERMS OF SUCH AGREEMENT AND THE SECURITIES ARE TRANSFERABLE ONLY UPON PROOF OF COMPLIANCE THEREWITH.

2.                                      RIGHT OF FIRST REFUSAL

2.1                               Selling Series C/D Shareholder and Notice.  Subject to Section 1.1, if any holder of Series C Shares, Series C-1 Shares, Series C-2 Shares or Series D Shares desires to Transfer any of his Series C Shares, Series C-1 Shares, Series C-2 Shares or Series D Shares or any interest in such Shares to a Third Party, in any transaction other than pursuant to Section 1.2 or Section 3.2 of this Agreement, such holder (the “Selling Series C/D Shareholder”), shall first deliver written notice of his desire to sell such Series C Shares, Series C-1 Shares, Series C-2 Shares and/or such Series D Shares (the “Series C/D Offer Notice”), to the Company and each of the holders of Series C Shares, Series C-1 Shares, Series C-2 Shares or Series D Shares in the manner prescribed in Section 8.9 of this Agreement.  Each Series C/D Offer Notice must specify:  (i) the name and address of the Third Party to which the Selling Series C/D Shareholder proposes to sell or otherwise dispose of the Shares or an interest in the Shares, (ii) the number of Series C Shares, Series C-1 Shares, Series C-2 Shares or Series D Shares (the “Series C/D Offered Shares”) the Selling Shareholder proposes to sell or otherwise dispose of, (iii) the consideration per Share to be delivered to the Selling Series C/D Shareholder for the proposed Transfer, (iv) the proposed date of the Transfer, and (v) all agreements related to and other material terms and conditions of the proposed transaction.

2.2                               Series C/D Offer Period.  Each holder of Series C Shares, Series C-1 Shares, Series C-2 Shares and/or Series D Shares (the “Series C/D Offerees”) shall have the right, exercisable for a period of ten (10) Business Days from the date of delivery of the Series C/D Offer Notice (the “Series C/D Offer Period”) to purchase, pro rata based on the number of Series C Shares, Series C-1 Shares, Series C-2 Shares and Series D Shares then owned by such Series C/D Offerees of all of the outstanding Series C Shares,

2.4                               Selling Shareholder and Notice.  Subject to Section 1.1, if any Shareholder desires to Transfer any of his Shares (other than any Series C Shares, Series C-1 Shares, Series C-2 Shares or Series D Shares, except Series C Shares, Series C-1 Shares, Series C-2 Shares or Series D Shares held by Management Shareholders), or any interest in such Shares to a Third Party, in any transaction other than pursuant to Section 1.2 or Section 3.2 of this Agreement, such Shareholder (the “Selling Shareholder”) shall first deliver written notice of his desire to do so (the “First Offer Notice”) to the Company and each of the holders of Series C Shares, Series C-1 Shares, Series C-2 Shares and Series D Shares in the manner prescribed in Section 8.9 of this Agreement.  The First Offer Notice must specify:  (i) the name and address of the Third Party to which the Selling Shareholder proposes to sell or otherwise dispose of the Shares or an interest in the Shares, (ii) the number of Shares the Selling Shareholder proposes to sell or otherwise dispose of (the “Offered Shares”), (iii) the consideration per Share to be delivered to the Selling Shareholder for the proposed Transfer, (iv) the proposed date of the Transfer, and (v) all agreements related to and other material terms and conditions of the proposed transaction.

2.7                               Final Offer Period.  In the event that all Offered Shares have not been elected to be purchased by the First Round Offerees or the Second Round Offerees pursuant to Section 2.5 and Section 2.6 respectively, the Company shall deliver written notice (the “Final Offer Notice”) of this to the First Round Offerees and Second Round Offerees that irrevocably elected to purchase their full pro rata portion of the Offered Shares pursuant to Section 2.5 and Section 2.6 (the “Final Round Offerees”) (such notice to be given in the manner prescribed in Section 8.9).  For a period of five (5) days after receipt of the Final Offer Notice (the “Final Offer Period”), each Final Round Offeree shall have the right, which right may be exercised by delivering written notice (a “Final Purchase Notice”) to the Company, with a copy to the Selling Shareholder, prior

(a)                                 Subject to the requirement in Section 2.8(b) that all the Offered Shares have been elected to be purchased, immediately after the final determination of the number of Offered Shares to be purchased by each of the Shareholders pursuant to Sections 2.4 through 2.7, the Company shall immediately notify all of such purchasing Shareholders of such determination.  The closing of the purchase of the Offered Shares shall take place at the offices of the Company no later than thirty (30) days after the date of such notice by the Company (provided, that, if any such Transfer is subject to regulatory approval, such 30-day period shall be extended until the expiration of five Business Days after all such approvals have been received, but in no event later than 120 days following the expiration of the First Offer Period), or at such other time and place as the parties to the transaction may agree.  At such closing, the Selling Shareholder shall deliver the certificate and other applicable instruments representing the Offered Shares and wire transfer instructions for payment of the consideration therefor, along with one or more assignment agreements transferring the Offered Shares to the relevant purchasing Shareholders.  In connection with the Transfer of the Offered Shares, the Selling Shareholder shall only be required to represent and warrant that the Offered Shares to be transferred shall be free and clear of any liens, claims or encumbrances (other than restrictions imposed by this Agreement and pursuant to applicable federal, state and foreign securities laws), that it is the record and beneficial owner of such Offered Shares, that it has all necessary power and authorization to consummate the Transfer, and that it has obtained or made all necessary consents, approvals, filings and notices from governmental authorities or third parties to consummate the Transfer.  The holders of Shareholders purchasing the Offered Shares shall deliver at such closing by certified or official bank check or by wire transfer of immediately available funds, payment in full for such Offered Shares.

3.                                      TAG-ALONG RIGHTS; DRAG-ALONG RIGHTS; PREEMPTIVE RIGHTS; CALL RIGHTS

3.1                               Tag-Along Rights.

(a)                                 Subject to Section 1.1, if a Shareholder (the “Tag-Along Seller”) desires to Transfer (a “Tag-Along Sale”) all or a part of his Shares (other than Fidelity Investors) to any Third Party in a single transaction or in a series of related transactions and such Offered Shares, as applicable, have been offered to, but not purchased by, the Shareholders in accordance with Section 2, the Tag-Along Seller shall first, by written notice to the Company, which shall provide the other Shareholders (the “Tag-Along Offerees”) with a copy of such notice (“Tag-Along Notice”), offer the Tag-Along Offerees (“Tag-Along Offer”) the opportunity to participate in such Transfer on an as converted basis in accordance with this Section 3.1 and Section 3.3.  The Tag-Along Notice must specify:  (i) the name and address of the party to which the Tag-Along Seller proposes to sell or otherwise dispose of the Shares or an interest in the Shares, (ii) the number of Offered Shares the Tag-Along Seller proposes to sell or otherwise dispose of pursuant to this Section 3.1(a), (iii) the consideration per Share to be delivered to the Tag-Along Seller for the proposed Transfer, (iv) the proposed date of the Transfer, and (v) all other material terms and conditions of the proposed transaction.

(b)                                 Upon receipt of the Tag-Along Notice, each Tag-Along Offeree shall have a fifteen (15) Business Day period after receipt of such notice (the “Tag-Along Notice Period”) in which to elect to sell Shares in the transaction by sending a notice (“Tag-Along Response Notice”) in writing to the Company (each such electing Tag-Along Offeree, a “Participating Seller”).  The Company shall promptly, on expiration of the Tag-Along Notice Period, notify the Tag-Along Seller of the aggregate number of Shares the Participating Sellers wish to sell.  Each Participating Seller shall have the right to sell an amount of Shares equal to the Shares the Third Party proposes to purchase multiplied by a fraction, the numerator of which shall be the number of Shares held by such Participating Seller, and the denominator of which shall be the aggregate number of

24

Shares held by the Tag-Along Seller and each Participating Seller, in each case on an as-converted basis.  For the purposes of this Section 3.1(b), Shares of a Management Shareholder shall exclude any Incentive Securities underlying any options for Common Shares, whether or not such options are vested, unless such options are exercised prior to the end of the Tag-Along Notice Period (as defined below).  The pricing of the Shares to be sold in a Tag-Along Sale shall be as set forth in Section 3.3(a).

(c)                                  The Tag-Along Response Notice shall include wire transfer instructions for payment of the purchase price for the Offered Shares to be sold by the Participating Seller in the Tag-Along Sale.  The Participating Sellers shall, upon request, deliver to the Tag-Along Seller, with the Tag-Along Response Notice, the certificate or certificates representing the Shares of such Participating Seller to be included in the Tag-Along Sale, together with a limited power-of-attorney authorizing the Tag-Along Seller to Transfer such Shares on the terms set forth in the Tag-Along Notice.  Delivery of the Tag-Along Response Notice with such certificate or certificates and limited power-of-attorney shall constitute an irrevocable acceptance of the Tag-Along Offer by the Participating Sellers.  In order to participate in a Tag-Along Sale, subject to Section 3.3(b), the Participating Sellers must agree to enter into and execute substantially identical agreements and documents as the Tag-Along Seller enters into and executes in connection with the Tag-Along Sale.

(d)                                 If, at the end of a 90-day period after the date of receipt of the Tag-Along Notice (provided that if such Tag-Along Sale is subject to regulatory approval, such 90-day period shall be extended until the expiration of five (5) Business Days after all such approvals have been received, but in no event later than 120 days after the date of receipt of the Tag-Along Notice), the Tag-Along Seller has not completed the Transfer of all of the Offered Shares to be sold pursuant to this Section 3.1 on substantially the same terms and conditions set forth in the Tag-Along Notice (but as to price, the terms shall be exactly the same), the Tag-Along Seller shall (i) promptly return to the Participating Sellers the limited power-of-attorney (and all copies thereof) together with all certificates representing the Offered Shares that such Participating Sellers delivered for Transfer pursuant to Section 3.1(c) and any other documents in the possession of the Tag-Along Seller executed by the Participating Sellers in connection with the proposed Tag-Along Sale, and (ii) not conduct any Transfer of such shares of the specified class of Offered Shares without again complying with this Section 3.1.

(e)                                  Concurrently with the consummation of the Tag-Along Sale, the Tag-Along Seller shall (i) notify the Participating Sellers thereof, (ii) remit or cause to be remitted to the Participating Sellers the total consideration to be paid at the closing of the Tag-Along Sale for the Shares of the Participating Sellers Transferred pursuant thereto, with the cash portion of the purchase price paid by wire transfer of immediately available funds in accordance with the wire transfer instructions in the Tag-Along Response Notice, and (iii) promptly after the consummation of such Tag-Along Sale, furnish such

25

other evidence of the completion and the date of completion of such Transfer and the terms thereof as may be reasonably requested by the Participating Sellers.

(f)                                   If at the termination of the Tag-Along Notice Period, any Tag-Along Offeree has not elected to participate in the Tag-Along Sale, such Tag-Along Offeree shall be deemed to have waived its rights under Section 3.1(a) with respect to, and only with respect to, the Transfer of its Shares pursuant to such Tag-Along Sale.

(g)                                  This Section 3.1 shall not apply to any Transfer of Company Securities (i) to the Investors, (ii) in a Drag-Along Sale, or (iii) that are Series D Shares.

3.2                               Drag-Along Rights

(a)                                 Subject to the approval rights of the holders of Series C Shares, Series C-1 Shares, Series C-2 Shares and Series D Shares as set forth in the Charter, in the event that holders representing more than fifty percent (50%) of the then issued Shares on an as converted basis (the “Drag-Along Seller”) wish to Transfer in a bona fide arm’s length transaction or series of transactions all of the Shares then owned by the Drag-Along Seller to any Person who is not an Affiliate of any Shareholders (the “Proposed Transferee”), the Drag-Along Seller shall have the right (the “Drag-Along Right”) to require all of the other Shareholders (the “Other Shareholders”) to sell to the Proposed Transferee all, and not only part, of the Shares then owned by such Shareholders (such transaction referred to in this Agreement as a “Drag-Along Sale”) on the same terms and conditions as the Drag-Along Sale, except as provided in Section 3.3(a).

(b)                                 As part of a Drag-Along Sale, the Drag-Along Seller shall also have the right to require that all of the Other Shareholders that hold warrants, options or other Company Securities that are convertible into or exchangeable or exercisable for Shares shall be exercised, exchanged or converted into Shares immediately prior to the consummation of the Drag-Along Sale and the Shares issued upon such exercise, exchange or conversion shall be included in the Drag-Along Sale.  Management Shareholders that hold options or warrants the exercise price per share of which is greater than the per share price at which the Shares are to be Transferred in connection with the Drag-Along Sale, if required by the Drag-Along Seller to exercise such options, may, in place of such exercise, submit to irrevocable cancellation thereof without any liability for payment of any exercise price with respect thereto.  If the Drag-Along Sale is not consummated with respect to any Shares acquired upon exercise of such options or warrants, such options or warrants shall be deemed not to have been exercised or canceled, as applicable.

(c)                                  The pricing of the Shares to be sold in a Drag-Along Sale shall be as set forth in Section 3.3(a).

26

(d)                                 Each Other Shareholder agrees with respect to all Company Securities that it holds or over which such Shareholder otherwise exercises dispositive power:

(1)                                 in the event such Drag-Along Sale requires the approval of shareholders (including in the case of a merger or sale or exclusive license of all or substantially of the all of the assets of the Company) and the matter is to be brought to a vote at a shareholder meeting, to be present, in person or by proxy, as a holder of Company Securities, at all such meetings and be counted for the purposes of determining the presence of a quorum at such meetings; and to vote or cause to be voted (or execute and deliver any written consents in lieu thereof) all Company Securities in favor of such Drag-Along Sale and in opposition of any and all other proposals that could reasonably be expected to delay or impair the ability of the Company to consummate such Drag-Along Sale if so requested by the Drag-Along Seller;

(2)                                 in the event that the Drag-Along Sale is to be effected by the sale of Shares held by the Drag-Along Seller without the need for shareholder approval, each Other Shareholder agrees to sell all Company Securities of the Company held by such Other Shareholder to the Proposed Transferee, for per-share consideration determined in accordance with the provisions of Section 3.3(a) and otherwise on the same terms and conditions as the Drag-Along Seller;

(3)                                 to the extent permitted by applicable law, to refrain from exercising any dissenters’ rights or rights of appraisal under applicable law at any time with respect to such Drag-Along Sale, provided it is conducted in accordance with this Section 3.2;

(4)                                 subject to Section 3.3(b), to execute and deliver all related documentation and take such other action in support of the Drag-Along Sale as shall be reasonably requested by the Company or the Drag-Along Seller and is required of all other Shareholders; and

(5)                                 not to deposit, and to cause their Affiliates not to deposit, any voting securities owned by such party in a voting trust or subject any such voting securities to any arrangement or agreement with respect to the voting of such shares of capital stock, unless specifically requested to do so by the acquiror in connection with a Drag-Along Sale.

(e)                                  If an Other Shareholder (other than any Fidelity Investor and their respective Affiliates) fails or refuses to vote or sell his, her or its Company Securities as required by, or votes his, her or its Company Securities in contravention of this Section 3.2, then such Other Shareholder (other than any Fidelity Investor and their respective Affiliates) hereby grants to the Drag-Along Seller a proxy coupled with an interest to vote such Shares in accordance with this Section 3.2, and hereby appoints the Drag-

27

Along Seller as his, her or its attorney in fact, to execute and deliver in the name and on behalf of such Other Shareholder all such agreements, instruments and other documentation (including any written consents of shareholders) as are required to Transfer the Company Securities held by such Other Shareholder to the Proposed Transferee in accordance with the terms of this Section 3.2.

(f)                                   To exercise a Drag-Along Right, the Drag-Along Seller shall give each Other Shareholder a written notice, whether before or after the consummation of the Drag-Along Sale and/or the approval of the Drag-Along Sale of the requisite stockholders of the Company (the “Drag-Along Notice”).  If the Drag-Along Notice is provided after the execution of definitive agreements with respect to the Drag-Along Sale and/or the approval of the Drag-Along Sale of the requisite stockholders of the Company, each Other Shareholder shall nonetheless comply with the provisions of this Section 3.2 and Section 3.3. The Drag-Along Notice shall identify (i) the name and address of the Proposed Transferee, and (ii) the proposed purchase price, terms of payment and other material terms and conditions of the Proposed Transferee’s offer.  Each Other Shareholder shall thereafter be obligated to sell its Company Securities subject to such Drag-Along Notice.

(g)                                  Not later than five (5) days after receipt of the Drag-Along Notice (the “Drag-Along Notice Period”), each of the Other Shareholders shall deliver to a representative of the Drag-Along Seller designated in the Drag-Along Notice the certificate and other applicable instruments representing the Company Securities of such Other Shareholder to be included in the Drag-Along Sale, together with wire transfer instructions for payment of the cash portion of the consideration to be received in such Drag-Along Sale, or, if such delivery is not permitted by applicable law, an unconditional agreement to deliver such Company Securities pursuant to this Section 3.2(g) at the closing for such Drag-Along Sale against delivery to such Other Shareholder of the consideration therefor.  If an Other Shareholder should fail to deliver such certificates to the representative of the Drag-Along Seller and the Drag-Along Sale is consummated, the Company shall cause the books and records of the Company to reflect that such Company Securities are bound by the provisions of this Section 3.2 and that such Company Securities shall be Transferred to the Proposed Transferee immediately upon surrender for Transfer by the holder thereof.

(h)                                 The Drag-Along Seller shall have a period of 120 days from the date of the Drag-Along Notice to consummate the Drag-Along Sale on the terms and conditions set forth in such Drag-Along Notice; provided, that if such Drag-Along Sale is subject to regulatory approval, such 120-day period shall be extended until the expiration of five (5) Business Days after all such approvals have been received, but in no event later than 180 days after the date of receipt of the Drag-Along Notice.  If the Drag-Along Sale shall not have been consummated during such period, the Drag-Along Seller shall promptly return to each of the Other Shareholders all certificates and other applicable instruments representing Company Securities that such Other Shareholders delivered for

28

Transfer pursuant hereto, together with any other documents in the possession of the Drag-Along Seller executed by the Other Shareholders in connection with such proposed Transfer, and all the restrictions on Transfer contained in this Agreement or otherwise applicable at such time with respect to such Company Securities owned by the Other Shareholders shall again be in effect.

(i)                                     Concurrently with the consummation of the Drag-Along Sale, the Drag-Along Seller shall give notice thereof to the Other Shareholders, shall remit or cause to be remitted to each of the Other Shareholders that has surrendered its certificates and other applicable instruments the total consideration to be paid at the closing of the Drag-Along Sale (the cash portion of which is to be paid by wire transfer of immediately available funds in accordance with such Other Shareholder’s wire transfer instructions) for the Company Securities Transferred by such Other Shareholder pursuant hereto, and shall furnish such other evidence of the completion and time of completion of such Transfer and the terms thereof as may be reasonably requested by such Other Shareholders.

(j)                                    Notwithstanding anything contained in this Section 3.2, there shall be no liability on the part of the Drag-Along Seller to the Other Shareholders (other than the obligation to return the certificates and other applicable instruments representing Company Securities received by the Drag-Along Seller) if the Transfer of Company Securities pursuant to this Section 3.2 is not consummated for whatever reason, regardless of whether the Drag-Along Seller has delivered a Drag-Along Notice.  The decision to effect a Transfer of Company Securities pursuant to this Section 3.2 by the Drag-Along Seller is in the sole and absolute discretion of the Drag-Along Seller.

3.3                               Additional Provisions Related to Tag-Along Sales and Drag-Along Sales.

Notwithstanding anything contained in Section 3.1 or Section 3.2 to the contrary, in connection with a Tag-Along Sale or a Drag-Along Sale:

(a)                                 Upon the consummation of such Tag-Along Sale or Drag-Along Sale, all Shareholders of the same series of Company Securities participating therein will receive the same form and amount of consideration per share, or, if any Shareholder of a specified series of Company Securities is given an option as to the form and amount of consideration to be received, all Shareholders of such specified series of Company Securities participating therein will be given the same option, and all holders of the Series C Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock and Series D Preferred Stock (or, in each case, Common Stock received upon conversion thereof) will receive the same form of consideration with respect to such Series C Preferred Stock, Series C-1 Preferred Stock, Series C-2 Preferred Stock and Series D Preferred Stock (or, in each case, Common Stock received upon conversion thereof); provided, however, that, in the case of a Drag-Along Sale or a Tag-Along Sale that constitutes a Liquidity Event,

29

the proceeds shall be allocated among the classes and series of Shares in accordance with the Charter.  If different classes or series of Shares are to be sold in a Tag-Along Sale and such sale does not constitute a Liquidity Event, the purchase price to be received by the Tag-Along Seller and the Participating Sellers shall be allocated after taking into account the relative value of the securities being transferred by each such Shareholder. The Board shall determine in good faith such relative value of each series and class of Shares to be sold in the Tag-Along Sale. For the avoidance of doubt, any fees paid to Avista Capital Holdings, LP or its affiliated investment funds in connection with any transaction constituting a Tag-Along Sale or Drag-Along Sale shall be considered in determining the amount of consideration per share referred to in the first sentence of this Section 3.3(a);

(b)                                 Each Shareholder shall (i) make such representations, warranties and covenants and enter into such definitive agreements as are customary for transactions of the nature of the proposed Transfer related to authority, ownership and the ability to convey title to such Company Securities, (ii) benefit from and be subject to all of the same provisions of the definitive agreements as are applicable to the Tag-Along Seller or Drag-Along Seller, as the case may be, (iii) subject to the provisions of the Company’s Certificate of Incorporation, be required to bear its proportionate share of any escrows, holdbacks or adjustments in respect of the purchase price or indemnification obligations; provided, that no Shareholder shall be obligated (A) to indemnify, other than severally indemnify, any Person in connection with such Tag-Along Sale or Drag-Along Sale, as the case may be, or (B) to incur liability to any Person in connection with such Tag-Along Sale or Drag-Along Sale, as the case may be, including, without limitation, under any indemnity, in excess of the lesser of (1) its pro rata share of such liability and (2) the proceeds realized by such Shareholder in such sale, and (iv) (other than any Fidelity Investor and their respective Affiliates) cooperate in obtaining all governmental and third-party consents and approvals reasonably necessary or desirable to consummate such Tag-Along Sale or Drag-Along Sale;

(c)                                  In the event the consideration to be paid in exchange for Shares in a Tag-Along Sale or a Drag-Along Sale includes any securities, and the receipt thereof by a Shareholder 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 Tag-Along Sale or a Drag-Along Sale or (b) the provision to any Tag-Along Seller or Drag-Along Seller of any specified information regarding such securities or the issuer thereof that is not otherwise required to be provided for the Tag-Along Sale or Drag-Along Sale, then such Shareholder may be paid cash in lieu of such securities in such proposed Tag-Along Sale or Drag-Along Sale.  In such event, the Tag-Along Seller or Drag-Along Seller, as the case may be, shall (i) in the case of a Tag-Along Sale, have the right, but not the obligation, and (ii) in the case of a Drag-Along Sale, have the obligation, to cause to be paid to such Shareholder in lieu thereof, against surrender of the Shares which would have otherwise been Transferred by such Shareholder to the prospective purchaser in the proposed Tag-Along Sale or a Drag-Along Sale, an amount in cash equal to the fair

30

market value (determined by the Board in good faith through a reasonable application of a reasonable valuation method) of such Shares as of the date such securities would have been issued in exchange for such Shares;

(d)                                 In connection with a Drag-Along Sale, if requested by a majority of the members of the Board, the Company will promptly engage, on customary terms (including customary indemnification from the Company), a nationally recognized investment banking firm selected by the Drag-Along Seller and reasonably acceptable to the Board to provide financial advisory services to the Company, the Drag-Along Seller and the Other Shareholders, and the Company shall pay the fees and expenses of such investment banking firm;

(e)                                  In connection with a Drag-Along Sale, the Company will, if applicable, enter into a definitive agreement with the proposed transferee(s) providing for such Transfer and make and agree to representations, warranties, covenants and indemnities and other similar agreements that are reasonable and customary for negotiated transactions of the type contemplated by such Transfer;

(f)                                   The Company agrees to cooperate with any Shareholder and any proposed transferee (other than a Company Competitor in the case of a Tag-Along Sale), and their respective advisors, to facilitate and effect any Tag-Along Sale or Drag-Along Sale and, upon the request of any Shareholder that proposes to make a Tag-Along Sale or Drag-Along Sale, subject to any proposed transferee (other than a Company Competitor in the case of a Tag-Along Sale) executing a reasonably satisfactory confidentiality agreement with the Company, the Company will, and will cause its and its Subsidiaries’ employees and personnel to, use its and their reasonable best efforts to facilitate and support any due diligence process being undertaken in connection with such proposed Tag-Along Sale or Drag-Along Sale;

(g)                                  The Company and the Shareholders (other than any Fidelity Investor and their respective Affiliates) will cooperate in the obtaining of all governmental and third-party approvals and consents reasonably necessary or desirable to consummate such Transfer;

(h)                                 All reasonable costs and expenses incurred by the Shareholders or the Company in connection with any proposed Drag-Along Sale (whether or not consummated), including all attorneys 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.  The Drag-Along Seller may retain, and the Company will pay the reasonable fees and expenses of, a single legal counsel (and such local counsel as may be appropriate) in connection with any proposed Drag-Along Sale (whether or not consummated). All reasonable costs and expenses incurred by the Shareholders in connection with any proposed Tag-Along Sale (whether or not consummated), including all attorneys fees and charges, all accounting fees and charges and all finders, brokerage

31

or investment banking fees, charges or commissions, shall be borne by each transferor of Shares;

(i)                                     No Fidelity Investor shall be bound by any restrictive covenant (such as any non-compete or other business limitation); and

(j)                                    All notices to be issued as part of the procedures relating to a Tag-Along Sale and a Drag-Along Sale set forth in Section 3.1 and Section 3.2 shall, as applicable, be made pursuant to Section 8.9.

3.4                               Preemptive Rights

(a)                                 Prior to the consummation of an Initial Public Offering, the Company shall give each of the Shareholders that is (i) an “accredited investor” (as such term is defined in Rule 501(a) of the Securities Act) or (ii) located outside the United States and is not a “U.S. Person” as such term is defined in Regulation S under the Securities Act (“Regulation S”) and that such Shareholder is obtaining the Company Securities in an “offshore transaction” (as such term is defined in Regulation S under the Securities Act) outside of the United States, each as of the time of any proposed issuance by the Company of shares of a specified class of Company Securities, written notice pursuant to Section 8.9 (an “Issuance Notice”) of such proposed issuance at least ten (10) days prior to the proposed issuance date.  The Issuance Notice shall specify the number of shares of the specified class of Company Securities and the price at which such Company Securities are proposed to be issued and the other material terms and conditions of the issuance, including, without limitation, the proposed closing date.  Subject to Section 3.4(f), each Shareholder shall be entitled to purchase, at the price and on the other terms and conditions specified in the Issuance Notice, its pro rata amount of such newly issued Company Securities equal to (x) the number of shares of the specified class of Company Securities proposed to be issued by the Company multiplied by (y) a fraction, the numerator of which is the aggregate number of Shares owned by such Shareholder and the denominator of which is the aggregate number of Shares owned by all Shareholders, in each case on an as-converted basis.

(b)                                 Each Shareholder may exercise its rights under this Section 3.4 by delivering written notice to the Company of its election to purchase such Company Securities within ten (10) days after receipt of the Issuance Notice.  A delivery of such notice (which notice shall specify the number of shares of the specified class of Company Securities requested to be purchased by the Shareholder submitting such notice) by such Shareholder shall constitute a binding agreement of such Shareholder to purchase, at the price and on the terms and conditions specified in the Issuance Notice, the number of shares of the specified class of Company Securities specified in such Shareholder’s notice.  If, at the termination of such 10-day period, any Shareholder has not exercised its right to purchase any of its pro rata share of such Company Securities, such Shareholder shall be deemed to have waived all of its rights under this Section 3.4 with respect to, and

32

only with respect to, the purchase of such Company Securities specified in the Issuance Notice.

(c)                                  The Company shall have 120 days after the date of the Issuance Notice to consummate the proposed issuance of any or all of such Company Securities that the Shareholders have elected not to purchase at the price and upon terms and conditions that are not materially less favorable to the Company than those specified in the Issuance Notice; provided, that if such issuance is subject to regulatory approval, such 120-day period shall be extended until the expiration of five (5) Business Days after all such approvals have been received, but in no event later than 180 days after the date of the Issuance Notice.  At the consummation of such issuance, the Company shall issue certificates representing the Company Securities to be purchased by each Shareholder exercising preemptive rights pursuant to this Section 3.4 registered in the name of such Shareholder, against payment by such Shareholder of the purchase price for such Company Securities.  If the Company proposes to issue any class of Company Securities after such 120-day period or on other terms materially less favorable to the issuer, it shall again comply with the procedures set forth in this Section 3.4.

(d)                                 The closing of any issuance of Company Securities to the Shareholders pursuant to this Section 3.4, shall take place at the time and in the manner provided in the Issuance Notice.  The Company shall be under no obligation to consummate any proposed issuance of Company Securities, nor shall there be any liability on the part of such entity to any Shareholder, if the Company has not consummated any proposed issuance of Company Securities pursuant to this Section 3.4 for whatever reason, regardless of whether it shall have delivered an Issuance Notice in respect of such proposed issuance.

(e)                                  Notwithstanding the requirements of this Section 3.4, the Company may offer and sell shares of a specified class of Company Securities without first offering such Company Securities to each of the other Shareholders or complying with the procedures of this Section 3.4, so long as (i) each of the other Shareholders receives prompt written notice of the consummation of such sales, (ii) either the Company or the initial purchaser of such Company Securities commits (at the time of such initial sale) to make available for sale to such Shareholders a number of shares of the specified class of Company Securities equal to (x) the number of shares of the specified class of Company Securities issued by the Company (including all shares of the specified class of Company Securities issued or sold to Shareholders with respect to this provision) multiplied by (y) a fraction, the numerator of which is the aggregate number of Shares owned by such Shareholder and the denominator of which is the aggregate number of Shares owned by all Shareholders, each determined on an as-converted basis, within 45 days after the close of such sale on the same terms and conditions as such prior sale, and (iii) the price per share of such specified class of Company Securities shall be identical to the price per share paid in such prior sale.

33

(f)                                   The preemptive rights under this Section 3.4 shall not apply to (i) issuances or sales of Company Securities to employees, officers, directors, consultants, customers or suppliers (including in connection with bona fide licensing, commercial or other strategic arrangements) of the Company or any Subsidiary pursuant to employee benefit, incentive or similar plans or agreements or arrangements of the Company, (ii) issuances or sales of Company Securities upon exercise, conversion or exchange of Company Securities outstanding as of the date hereof, (iii) Common Shares issued pursuant to conversion of preferred shares pursuant to Section 4.7 of the Charter, securities issued in connection with a stock split or stock dividend of the Company, (iv) the issuance of Company Securities to banks, equipment lessors or other financial institutions, or to real property lessors, pursuant to a debt financing, equipment leasing or real property leasing transaction, (v) the issuance of Company Securities contemplated by the Subscription Agreement (including any Series D Shares issued pursuant to Sections 1.2 through 1.3 of the Subscription Agreement), (vi) issuances or sales in an Initial Public Offering, or as consideration for a merger of the Company with or into another Person or an acquisition by the Company of another Person or substantially all the assets of another Person, (vii) issuances as consideration for sponsored research, collaboration, technology license, development, OEM, marketing or other similar agreements or strategic partnerships approved or (viii) any Series C-2 Shares issued pursuant to the Note Conversion Agreement, in each case of (i) — (vii) as approved in accordance with the Charter.

3.5                               Call Right.

(a)                                 Upon any Management Shareholder ceasing to be employed by, or providing services to, the Company or one of its Subsidiaries (a “Terminated Shareholder”) for any reason (a “Termination Event”), subject to the provisions of this Section 3.5, the Company shall have the option to purchase (the “Call Right”), and if such option is exercised, such Terminated Shareholder shall sell, and shall cause any Permitted Transferees of such Terminated Shareholder to sell, to the Company all or any portion of the Company Securities (A) that are Purchased Securities acquired, prior to and as of the date of the occurrence of such Termination Event (the “Termination Date”), or (B) that are Incentive Securities acquired prior to and as of the Termination Date, or acquired after such Termination Date pursuant to the exercise of Common Shares options in accordance with the terms of such Common Shares options (together with all Purchased Securities, the “Termination Securities”), at a price per Termination Security equal to the applicable Termination Price (as determined pursuant to Section 3.5(d) below) of the Termination Securities. The Company may assign all or a portion of the Call Right to the Avista Investors or Fidelity Investors on a pro rata basis (based on their respective ownership on an as-converted basis of Shares).  If the Call Right is assigned, the Avista Investors and Fidelity Investors shall have the rights and benefits granted to the Company in this Section 3.5.

34

(b)                                 With respect to each Termination Security, the Company shall notify a Terminated Shareholder in writing, within the Call Period with respect to such Termination Security, whether the Company will exercise its right to purchase such Termination Security (the date on which a Terminated Shareholder is so notified, the “Call Notice Date”).

(c)                                  The closing of the purchase by the Company of Termination Securities pursuant to this Section 3.5 shall take place at the principal office of the Company on the date chosen by the Company, which date shall, except as may be reasonably necessary to determine the Termination Price, in no event be more than forty-five (45) days after the Call Notice Date.  At such closing, (i) the Company shall pay the Terminated Shareholder and/or such Terminated Shareholder’s Permitted Transferees, as applicable, against delivery of duly endorsed certificates described below representing such Termination Securities, the aggregate Termination Price by wire transfer of immediately available federal funds and (ii) the Terminated Shareholder and/or such Terminated Shareholder’s Permitted Transferees, as applicable, shall deliver to the Company a certificate or certificates representing the Termination Securities to be purchased by the Company duly endorsed, or with stock powers duly endorsed, for transfer with signature guaranteed, free and clear of any lien or encumbrance, with any necessary stock transfer tax stamps affixed.  The delivery of a certificate or certificates for the Termination Securities by any Person selling such Termination Securities pursuant to this Section 3.5 shall be deemed a representation and warranty by such Person that: (A) such Person has full right, title and interest in and to such Termination Securities; (B) such Person has all necessary power and authority and has taken all necessary action to sell such Termination Securities as contemplated; (C) such Termination Securities are free and clear of any and all liens or encumbrances; and (D) there is no adverse claim with respect to such Termination Securities.

(d)                                 Termination Price.  For purposes of this Section 3.5, if the employment or other service arrangement of a Management Shareholder is terminated, the “Termination Price” per Termination Security purchased by the Company pursuant to the Call Right shall equal the value as set forth below:

35

For purposes of this Section 3.5(d), “Fair Market Value” shall be the Fair Market Value on the FMV Calculation Date.

(e)                                  Payment.  The Company shall pay the Termination Price in cash, by wire transfer of immediately available federal funds.

(f)                                   Termination of Call Right.  The Call Rights under this Section 3.5 shall terminate one (1) year after the consummation of the Initial Public Offering.

4.                                      BOARD OF DIRECTORS

4.2                               Removal of Directors.  The Shareholders agree that each party who has the right to designate member(s) of the Board pursuant to Section 4.1 shall also have the right to remove such designee from the Board at any time.  Each of the Shareholders agrees to take whatever action is necessary to effect any removal requested by such party.  No Shareholder shall, at any time it is then entitled to vote for the removal of directors from the Board, vote any of its Company Securities in favor of the removal of any director designated pursuant to Section 4.1, unless the designating party shall have requested such removal in writing.

4.3                               Replacement Directors.  If any director is unable to serve, or is removed or withdraws from the Board, such withdrawing director’s replacement will be designated by the party which designated such director in accordance with Section 4.1 and each Shareholder then entitled to vote for the election of directors to the Board shall vote all of its Company Securities that are entitled to vote or execute proxies or written consents, as the case may be, in order to ensure that the such replacement designee is elected to the Board (or to take whatever action is necessary to effect any replacement requested by such party).  If such designating party is no longer a Shareholder, or is no longer entitled to designate a replacement director, the withdrawing director’s replacement will be elected by the then-current shareholders by majority vote of all Shares on an as-converted basis.

4.4                               Unfilled Vacancy.  Any parties entitled to appoint director(s) in accordance with Section 4.1 may, in their sole discretion, decide not to elect one or more such directors, and during any period when there is a vacancy on the Board as a result of such decision not to appoint one or more directors, the Board shall not be deemed unduly constituted solely as a result of such vacancy.

4.5                               Observers.  Observers may participate in board meetings from time to time subject to Board approval; provided, however, that as long as the Fidelity Investors collectively own not less than twenty-five percent (25%) of the Series D Shares they are

37

purchasing under the Subscription Agreement (or an equivalent amount of Common Shares issued upon conversion thereof), in the aggregate, the Company shall invite a representative of the Fidelity Investors to attend all meetings of its Board of Directors and any committees thereof in a nonvoting observer capacity and, in this respect, shall give such representative (and the Fidelity Investors) copies of all notices, minutes, consents, and other materials that it provides to its directors at the same time and in the same manner as provided to such directors. Observers are not entitled to vote; provided, however, that the Fidelity Investors shall cause such observer to hold in confidence and trust all information so provided to the extent required by Section 5.4; and provided further, that the Company reserves the right to withhold any information and to exclude such observer from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest, or if such representative is associated with a Company Competitor (but not solely by virtue of any investments that any Fidelity Investor may have in a Competitor).

4.6                               Actions by the Board of Directors.  Except as otherwise set forth herein or required by law, all decisions of the Board shall require the affirmative vote of a majority of its members.

4.7                               Quorum.  A quorum of the Board shall consist of a majority of the members of the Board being present in person or by telephone, which majority shall include at least two Series C Directors, provided, however, that if all Series C Directors have failed to attend three consecutive Board meetings (in person or telephonic) without a bona fide reason and after notice has been duly provided in accordance with the Bylaws, a Series C Director shall not be required for a quorum at the next such Board meeting.

4.8                               Committees.  In addition to any committees formed by the Board in accordance with its Charter and Bylaws from time to time, the Board shall establish a compensation committee and an audit committee which shall at all times include at least one Series C Director.

4.9                               Subsidiaries.  The board of directors (and any committees thereof) of all Subsidiaries of the Company will consist of such persons as the Company shall direct; provided, that the holders of Series C Shares shall have the right to appoint members to such board of directors (or committees) in the same proportions as set forth in Section 4.1.

4.10                        Expenses.  The Company shall reimburse the members of the Board and the representative designated pursuant to Section 4.5 for all reasonable out-of-pocket travel expenses and attendant costs related to attending Board meetings and otherwise providing services on behalf of the Company or its Subsidiaries in their capacity as directors.

(a)                                 Each Shareholder that (collectively with its Affiliates) is a beneficial owner of 20% or more of the Company or has the right to designate a director of the Company pursuant to the provisions of Section 4.1 hereby represents and warrants that:

(1)                                 neither it nor any related party described in Rule 506(d)(1) of the Securities Act (“Beneficial Owner”) is subject to any of the “bad actor” disqualifications described in Rule 506(d)(1)(i) through (viii) under the Securities Act (“Disqualification Events”), included as Schedule 4.11(a) attached hereto, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act and disclosed in writing in reasonable detail to the Company and the other Shareholders;

(5)                                 no Director designated by it under Section 4.1 is subject to a Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act and disclosed in writing in reasonable detail to the Company and the other Shareholders.

(b)                                 Each Shareholder that (collectively with its Affiliates) is a beneficial owner of 20% or more of the Company or has the right to designate a director of the Company pursuant to the provisions of Section 4.1 agrees to exercise reasonable care to determine whether any of its designated or potential Directors or any Beneficial Owner is subject to any Disqualification Event, and shall promptly provide the Company and the other Shareholders to this Agreement with any and all information reasonably requested by the Company or otherwise necessary for the Company to determine, in the exercise of reasonable care, whether any designated or potential Director or Beneficial Owner is subject to any Disqualification Event.  Each Shareholder that has the right to designate a director of the Company pursuant to the provisions of Section 4.1 agrees that it will not designate a Director that is subject to any Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the

39

Securities Act. With respect to any such Disqualification Event covered by Rule 506(d)(2)(ii) or (iii) or (d)(3), the relevant Shareholder will promptly disclose in writing to the Company and the other Shareholders any and all information necessary for the Company to determine whether Rule 506(d)(2)(ii) or (iii) or (d)(3) applies.  Each Shareholder that (collectively with its Affiliates) is a beneficial owner of 20% or more of the Company or has the right to designate a director of the Company pursuant to the provisions of Section 4.1 will promptly notify the Company and each other Shareholder in writing if it, any Beneficial Owner or, to its knowledge, any of its designated or potential Directors is subject to any Disqualification Event.

(c)                                  Notwithstanding any other provision in this Agreement to the contrary, no Shareholder shall be required to vote to elect (or maintain in office) any person that is subject to a Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act.

(d)                                 From time to time during the term of this Agreement, any Shareholder may request the removal of a director that is subject to any Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act, by written notice to the Company and the other Shareholders specifying, in reasonable detail, the Disqualification Event.  If the Company reasonably determines that a Director is subject to a Disqualification Event, except for Disqualification Events covered by Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act:

(1)                                 the Company shall promptly notify each Shareholder to this Agreement and take such reasonable actions as are necessary to facilitate such removal, including, without limitation, soliciting the votes of the appropriate shareholders; and

(2)                                 the Shareholders shall vote their Company Securities to cause the removal from the Company’s Board of the Director.
