 RECITALS

Series B Participating Preferred Stock of the Company, par value $0.01 per share (the “Series B Preferred Stock”), and the Company are signatories to that certain Amended and Restated Shareholders Agreement, dated as of November 1,
2002 (the “Prior Agreement”). 
  
 B. The Company
wishes to issue and sell to certain investors (the “Series C Investors”) 5,573,770 shares of Series C Participating Preferred Stock of the Company, par value $0.01 per share (the “Series C Preferred Stock”, and,
together with Series B Preferred Stock, the “Preferred Stock”) pursuant to a that certain Stock Purchase Agreement by and among the Company and the Series C Investors, dated as of the date hereof (the “Stock Purchase

 C. In connection with the purchase of
Series C Preferred Stock by the Series C Investors, the parties wish to amend and restate the Prior Agreement effective upon consummation of the transactions contemplated by the Stock Purchase Agreement. 
  
 NOW, THEREFORE, in consideration of the mutual promises made herein and other
good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree that the Prior Agreement is hereby amended and restated in its entirety as follows: 

 
 1. Representations and Warranties. Each Shareholder represents and
warrants that (i) immediately after consummation of the transactions contemplated by the Stock Purchase Agreement, such Shareholder is the beneficial owner of that number and class of Restricted Securities set forth opposite its name on the
Schedule of Shareholders attached hereto and (ii) this Agreement has been duly authorized, executed and delivered by such Shareholder and constitutes the valid and binding obligation of such Shareholder, enforceable in accordance with its
terms. 

 2. Restrictions on Transfer of Restricted Securities. 
  
 (a) Retention of Restricted Securities. 
  
 No Shareholder shall Transfer (whether with or without consideration and
whether voluntarily or involuntarily or by operation of law) any interest in any Restricted Securities except pursuant to (A) an Exempt Transfer, (B) a Public Sale or (C) the provisions of Sections 2(b) and 2(c) or Section 4 hereof. 
  
 (b) Right of First Refusal. 
  
 (i) At least 30 days prior to any Transfer of Restricted Securities other
than Cisco Common Stock (except pursuant to (A) an Exempt Transfer, (B) a Public Sale or (C) Section 4 hereof), any Shareholder desiring to make such Transfer (the “Transferring Shareholder”) shall deliver a written notice (the
“Offer Notice”) to the Company and each other holder of Preferred Securities, specifying in reasonable detail the identity of the prospective Transferee(s), the number and type of Restricted Securities to be Transferred (the
“Offered Securities”) and the price and other material terms and conditions of the proposed Transfer. The Transferring Shareholder shall not consummate such proposed Transfer until at least forty (40) days after the delivery of the
Offer Notice, unless the parties to the Transfer have been finally determined pursuant to this Section 2 prior to the expiration of such 40-day period (the “Election Period”). 
  
 (ii) First, the Company may elect to purchase all or any portion of the
Offered Securities at the price and on the terms and conditions specified in the Offer Notice by delivering written notice of such election to the Transferring Shareholder and each other holder of Preferred Securities as soon as practical but in any
event within ten (10) days after the delivery of the Offer Notice. If the Company has not elected to purchase all of the Offered Securities within such ten-day period, each other holder of Preferred Securities may elect to purchase all of his, her
or its Pro Rata Share (as defined below) of the Restricted Securities specified in the Offer Notice that the Company has not elected to purchase at the price and on the terms and conditions specified therein by delivering written notice of such
election to the Transferring Shareholder and the Company as soon as practical but in any event within twenty (20) days after delivery of the Offer Notice. Any Offered Securities not elected to be purchased by the end of such 20-day period shall be
reoffered (and reoffered, until they are fully subscribed) for the ten-day period prior to the expiration of the Election Period by the Transferring Shareholder on a pro rata basis to the holders of Preferred Securities who have elected to purchase
their Pro Rata Share. The “Pro Rata Share” of each holder of Preferred Securities shall be based upon such holder’s proportionate ownership of all Restricted Securities owned by holders of Preferred Securities other than the
Transferring Shareholder. 
  
 (iii) If the Company and/or any
other holders of Preferred Securities have elected to purchase all of the Offered Securities from the Transferring Shareholder, the Transfer of such securities shall be consummated as soon as practical after the delivery of the election notice(s) to
the Transferring Shareholder, but in any event within fifteen (15) business days after the expiration of the Election Period; provided that the Company or any purchasing holder may elect to require such Transfer to be consummated effective as
of the first day of the next succeeding month. Notwithstanding any other provision hereof, in the event that the sale price, or any portion thereof, for the Offered Securities is not payable in the form of cash at 

  

 2 

 
closing or cash payable on a defined basis (such as pursuant to simple promissory notes issued by the prospective Transferee(s) described in the Offer
Notice), the Company and/or each holder of Preferred Securities electing to purchase Offered Securities pursuant to this subsection shall be required to pay only such portion, if any, of the sale price described in the Offer Notice that consists of
such cash consideration, and delivery of such consideration to the Transferring Shareholder shall be payment in full for such Offered Securities. 
  
 (iv) If the Company and the holders of Preferred Securities (collectively) have not elected to purchase all of the Offered Securities, all elections to
purchase such Offered Securities shall be null and void and the Transferring Shareholder shall have the right, within 90 days after the expiration of the Election Period and subject to the provisions of subsection (c) below, to Transfer all (but not
fewer than all) of the Offered Securities to the Transferee(s) specified in the Offer Notice in the amount(s) specified in the Offer Notice at a price not less than the price per security and on other terms and conditions specified in the Offer
Notice. Any Offered Securities not Transferred within such 90-day period shall be reoffered to the Company and the other holders of Preferred Securities under this Section 2(b) prior to any subsequent Transfer (other than an Exempt Transfer, a
Public Sale or pursuant to Section 4 hereof). 
  
 (c) Tag-Along
Rights. 
  
 (i) Except pursuant to (A) an Exempt Transfer,
(B) a Public Sale or (C) Section 4 hereof, any holder of Preferred Securities may elect to participate in any sale of Offered Securities by a holder of Restricted Securities (other than Cisco Common Stock) to one or more third parties or to any
other Shareholder (each a “Purchaser”) at the same price and on the same other terms and conditions applicable to the Transferring Shareholder by giving written notice of such election to the Transferring Shareholder within 30 days
after delivery of the Offer Notice. In the event that the number of Offered Securities proposed to be Transferred as described in the Offer Notice (or, if such transaction is part of a group of related transactions, the aggregate number of Offered
Securities to be Transferred to one or more Purchasers in all such related transactions) is equal to at least 30% of the aggregate number of the Common Stock then outstanding (on an as converted basis) and the price for the Offered Securities
specified in the Offer Notice is greater than the sum of the aggregate purchase price paid to the Company for such Offered Securities at their initial issuance plus the accrued and unpaid dividends thereon, if any (such a Transfer being a
“Common-Eligible Transfer”), then, (A) the Offer Notice shall promptly be delivered to the holders of Common Securities, and (B) each holder of Common Securities may elect to participate in such sale of Offered Securities to one or
more Purchasers by giving written notice of such election to the Transferring Shareholder within 30 days after such delivery of the Offer Notice. In any such sale to one or more Purchasers, each holder of Restricted Securities shall receive in
consideration of the Restricted Securities to be sold to such Purchaser(s) by such holder the same portion of the aggregate consideration from such transaction that such holder of Restricted Securities would have received in respect of such
Restricted Securities if such aggregate consideration had been distributed in a dissolution and liquidation of the Company in accordance with the Certificate of Incorporation. 
  
 (ii) In any Common-Eligible Transfer, “Eligible Securities” means all Preferred Securities and all Common
Securities then outstanding on an as converted basis and in 

  

 3 

 
the case of Common Securities subject to an Executive Purchase Agreement, then fully vested, and in any other sale pursuant to Section 2(c)(i),
“Eligible Securities” means all Preferred Securities then outstanding on an as converted basis. In any contemplated sale pursuant to Section 2(c)(i), the Transferring Shareholder and any holder that elects to participate in such sale will
be entitled to include in such sale that number of Eligible Securities equal to the product of (x) the quotient determined by dividing the percentage of Eligible Securities held by such Shareholder by the aggregate percentage of Eligible Securities
held by all participating Shareholders (including the Transferring Shareholder) times (y) the number of Offered Securities to be sold in such sale; provided that if any holder of Eligible Securities elects to include part, but not all, of such
holder’s pro rata share, then the number of Eligible Securities that any electing holder is eligible to include, but does not elect to include, in such sale may be sold in such sale by the Transferring Shareholder. 
  
 For example, if the Offer Notice contemplated a sale of 1,000 shares of
Preferred Stock by the Transferring Shareholder, and if the Transferring Shareholder at such time owns 55% of all Eligible Securities and if one other holder elects to participate and such holder owns 20% of all Eligible Securities, the Transferring
Shareholder would be entitled to sell 733 Eligible Securities (55% divided by 75% (i.e., .55 ÷ .75) x 1,000 securities) and the other holder would be entitled to sell 267 Eligible Securities (20% divided by 75% (i.e., .20 ÷ .75) x
1,000 securities). 
  
 If a Shareholder holds both Preferred Securities and Common
Securities and elects to participate in a Common-Eligible Transfer, then the ratio of the number of Common Securities included in such sale by such holder to the number of Preferred Securities included in such sale by such holder may not exceed the
ratio of the total number of Common Securities held by such holder to the total number of Preferred Securities on an as converted basis held by such holder. For example, if such holder holds 500 Preferred Securities and 250 Common Securities, then
no more than one-third (1/3) of the Eligible Securities to be included in such sale by such holder may be Common Securities. 
  
 (iii) Each Transferring Shareholder shall use best efforts to obtain the agreement of the prospective Transferee(s) to the participation of the electing
Shareholders in any contemplated sale and to the inclusion (if requested by any such holder) of any Restricted Securities held by such holder in the contemplated sale, and no Transferring Shareholder shall Transfer any of its Restricted Securities
to any prospective Transferee(s) unless (A) such prospective Transferee(s) agree to allow the participation of all electing Shareholders and to the inclusion of the Restricted Securities held by such holders, or (B) the Transferring Shareholder
purchases from each electing Shareholder the same number and type of securities (at the same price and on the same terms) that such participating Shareholder would have been entitled to sell had the prospective Transferee(s) so agreed. 

 
 (iv) Each Shareholder Transferring securities pursuant to this Section
2(c) shall pay its pro rata share (based on the aggregate amount of the purchase price received in respect of the Restricted Securities to be Transferred by such Shareholder) of the expenses incurred by all of the Shareholders in connection with
such Transfer and shall be obligated to participate severally on a pro rata basis (based on the aggregate amount of the purchase price 

  

 4 

 
received in respect of the Restricted Securities to be Transferred by such Shareholder) in any indemnification or other obligations that the Transferring
Shareholder agrees to provide in connection with such Transfer (other than any such obligations that relate solely to a particular Shareholder, such as indemnification with respect to representations and warranties given by a Shareholder regarding
such Shareholder’s title to and ownership of Restricted Securities, in respect of which only such Shareholder shall be liable); provided that no holder shall be obligated in connection with such Transfer to agree to indemnify or hold
harmless the Transferee(s) with respect to an amount in excess of the net cash proceeds paid to such holder in connection with such Transfer. 
  
 (d) Permitted Transfers. For purposes of this Agreement, a “Permitted Transfer” shall mean any Transfer of Restricted Securities
(i) to an Affiliate of the Transferor, (ii) to any Person acquiring all or substantially all of the Transferor’s portfolio investments, (iii) in the case of any Shareholder that is a partnership or a limited liability company, to such
Person’s partners or members or Affiliates of such partners or members, (iv) in the case of any Shareholder who is an individual, to such Shareholder’s Family Group, (v) to any Person whose association with the Company Parties would, in
the good faith judgment of the holders of a majority of the Preferred Securities then outstanding, be beneficial to the Company Parties by virtue of such Person’s experience, expertise, or knowledge in the telecommunications services industry
or related industries or (vi) to another Shareholder, but only of the Common Stock issued in the Merger and to the extent that such Common Stock does not exceed, in the aggregate during the term of this Agreement, 1% of the total Restricted
Securities held by all Shareholders on the date thereof; provided that in each case the restrictions, conditions, and obligations contained in this Agreement and the Stock Purchase Agreement shall continue to be applicable to such Restricted
Securities after any such Permitted Transfer, and the Transferee(s) of such Restricted Securities shall have agreed in writing to be bound by the provisions of such agreements; and provided further that the Restricted Securities Transferred
pursuant to clause (v) hereof shall not exceed, in the aggregate, 10% of the total Restricted Securities held by all Shareholders on the date hereof; and provided further that each Shareholder shall have the right to participate (subject to
the proviso set forth below) in any Transfer pursuant to clause (v) hereof pro rata, based on the number of Preferred Securities held by each such Preferred Shareholder on the date of such Transfer. For purposes of this Agreement, “Family
Group” means a Shareholder’s spouse, descendants (whether natural or adopted), parents, spouse’s parents, siblings, nieces and nephews, any spouse of the foregoing (collectively, the “Family”), any trust which at
the time of such Transfer and at all times thereafter is and remains solely for the benefit of such Shareholder and/or such Shareholder’s Family and any family partnership the partners of which consist solely of such Shareholder, such
Shareholder’s Family or such trusts. 
  
 (e) Termination
of Restrictions. The restrictions on the Transfer of Restricted Securities set forth in this Section 2 shall continue with respect to each such security (and shall survive any Transfer thereof) until the earliest to occur of (A) the completion
of a Sale of the Company, or (B) the consummation of a Public Offering. 
  
 3. Sale of the Company. 
  
 (a) Obligation of
Shareholders. If the holders of a majority of the Preferred Securities then outstanding approve a Sale of the Company (an “Approved Sale”), each holder of 

  

 5 

 
Restricted Securities shall vote for, consent to and raise no objections against such Approved Sale. If the Approved Sale is structured (i) as a merger or
consolidation, each holder of Restricted Securities (as applicable) shall waive any dissenters rights, appraisal rights or similar rights in connection with such merger or consolidation or (ii) as a sale of securities, each holder of Restricted
Securities (as applicable) shall agree to sell all of its shares of the Company’s capital stock on the terms and conditions approved by the holders of a majority of the Preferred Securities. Each holder of Restricted Securities shall take all
necessary or desirable actions in connection with the consummation of the Approved Sale as requested by the holders of a majority of Preferred Securities then outstanding. 
  
 (b) Conditions to Obligation. The obligations of the Shareholders with respect to an Approved Sale are subject to the
satisfaction of the following conditions: (i) upon the consummation of the Approved Sale, each holder of a class of securities shall receive the same form of consideration and the same amount of consideration for each security of such class to be
sold in such Approved Sale, (ii) if any holders of Restricted Securities are given an option as to the form and amount of consideration to be received, each holder of Restricted Securities shall be given the same option, (iii) no holder of
Restricted Securities shall be subject to any obligation or liabilities which adversely affect such holder relative to its effect on other holders of the same class or type of Restricted Securities without such holder’s consent and (iv) if the
Approved Sale consists of a transaction which would be a Liquidation Event (as defined in the Certificate of Incorporation), each holder of Restricted Securities shall receive the amounts and form of consideration required under the Certificate of
Incorporation. 
  
 (c) Public Offering. In the event that
holders of a majority of the Preferred Securities approve an initial Public Offering, the holders of the Restricted Securities shall take all reasonable actions in connection with the consummation of such Public Offering as requested by the Company.

  
 (d) Termination. The provisions of this Section 3 shall
terminate upon the earlier to occur of (i) the consummation of a Public Offering and (ii) the completion of a Sale of the Company. 
  
 4. Put Provisions. 
  
 (a) Put Right. 
  
 (i) At any time and from time to time on or after November 1, 2007 (so long as it is not prohibited by, or would not otherwise result in a default under,
the Amended Credit Agreement (as such term is defined in Section 2.12 of the Stock Purchase Agreement)) but not after the consummation of a Public Offering or a Sale of the Company, upon the affirmative vote or written consent of the holders of a
majority of the Preferred Securities then outstanding, the Company shall be required to repurchase all (but not less than all) of the outstanding Preferred Securities at the Repurchase Price (as defined below). Within 5 days following the
affirmative vote or written consent referenced above, the holders of a majority of the Preferred Stock then outstanding shall give written notice to the Company of the exercise of this right (an “Exercise Notice”) and promptly after
receipt of the Exercise Notice, the Company shall send written notice thereof to all other Shareholders holding Preferred Stock. 
  
  

 6 

 (ii) Within thirty (30) days after receipt of any Exercise Notice, the Company shall give written notice
(the “Repurchase Notice”) to the holders of Preferred Securities, setting forth a reasonable approximation of the Fair Market Value of the Company at the time of such Repurchase Notice. Each holder of Preferred Securities shall be
required to join in such repurchase on the same terms and conditions as set forth in the Exercise Notice. 
  
 (iii) Promptly (but in any event within five (5) business days after the end of this 30-day period), the Company and the holders of a majority of the
Preferred Securities to be repurchased shall determine the Repurchase Price as provided in Section 4(c) below, and (subject to the provisions hereof) within ten (10) days after the determination of the Repurchase Price, the Company shall purchase
and the holders of Preferred Securities shall sell all outstanding Preferred Securities at a mutually agreeable time and place; provided that the Company may, at its option, require that such purchase and sale of Preferred Securities occur
effective as of the first day of the next succeeding month. 
  
 (iv) Subject to applicable law, in the event the Company does not have adequate funds available to fully repurchase all of the Preferred Securities pursuant to this Section 4 at the time scheduled for the closing of such purchase, the
Company shall repurchase from each holder of Preferred Securities to be repurchased, their pro rata share of all Preferred Securities to be repurchased. The Company shall then use its best efforts (but subject to the fiduciary duties of the Board
and applicable law) to obtain adequate funds to satisfy the remainder of its repurchase obligation under this Section 4. 
  
 (b) Duties of the Company. Subject to applicable law and the fiduciary duties of the Board, the Company shall use its best efforts (including (i)
the Company assuming or refinancing debt, obtaining waivers or consents from its lenders, and (ii) causing a Public Offering, recapitalization, or Sale of the Company to occur) in order to satisfy its repurchase obligations under this Section 4.

  
 (c) Repurchase Price. 
  
 (i) The repurchase price for each Preferred Security repurchased by the
Company under this Section 4 (the “Repurchase Price”) shall be equal to the greater of the Original Cost of such security or the amount such Preferred Security would be entitled to receive under the Certificate of Incorporation in
the event the then Fair Market Value of the Company at the time of repurchase was distributed in a Liquidation Event. 
  
 (ii) The “Original Cost” of any Preferred Securities to be repurchased pursuant to this Section 4 shall be equal to the Liquidation
Value (as defined in the Certificate of Incorporation) of such Preferred Securities. 
  
 (iii) The “Fair Market Value” of the Company shall be determined as follows: 
  
 (A) The Company and the holders of a majority of the Preferred Securities shall attempt in good faith to agree on the Fair Market Value of the Company.
Any agreement reached by such Persons shall be final and binding on the Company and all holders of Preferred Securities. 
  

 7 

 (B) If such Persons are unable to reach agreement pursuant to Section 4(c)(iii)(A) within twenty (20)
days: 
  
 1) Each of the Company, on the one hand, and the
holders of a majority of the Preferred Securities, on the other hand, shall, within fifteen (15) days thereafter, choose one investment banker or other appraiser experienced in analyzing and making determinations concerning matters relating to the
telecommunications industry and in valuing entities like the Company, and the two investment bankers/appraisers so selected shall together select a third investment/banker appraiser similarly qualified. 
  
 2) The three investment bankers/appraisers so selected shall each appraise
the fair market value of the Company (based on the assumption of an orderly, arm’s length sale to a willing unaffiliated buyer). Each of the three investment bankers/appraisers shall, within thirty days of its retention, provide the written
results of such appraisals to the Company to each holder of Preferred Securities. 
  
 3) For purposes of this Section 4(c), the “Fair Market Value” of the Company shall be the amount agreed upon, as described in Section 4(iii)(A) or, if no such agreement was reached, the average of the
two appraisals thereof closest in amount to each other (or the appraisal which is neither the greatest nor the least in amount, if no two appraisals are closest in amount), and such determination shall be final and binding on the Company and all
holders of Preferred Securities. 
  
 4) The costs of the
appraisal shall be borne by the Company. 
  
 5. Covenants of
the Company. 
  
 (a) Financial Statements and Other

whether the Company has met its budgeted financial goals (including those specified in any business plan approved by the Board of Directors (an “Approved Business Plan”) and those delivered pursuant to subsection 5(a)(iv) below),
discussing the reasons for any variation from such goals, and describing what actions the Company and its Subsidiaries have taken and propose to take in order to meet budgeted financial targets in the future;

promptly upon preparation thereof any other significant budgets prepared by the Company and any revisions of such annual or other budgets (it being understood that any revisions of any Approved Budget must be approved by the Board); 
  

 9 

 (vi) promptly (but in any event within five (5) business days) after the discovery or
receipt of notice of any material default by the Company under any material agreement to which the Company or any of its Subsidiaries is a party, any condition or event which is reasonably likely to result in any material liability under any
federal, state or local statute or regulation relating to public health and safety, worker health and safety or pollution or protection of the environment or any other material adverse change, event or circumstance affecting the Company or any of
its Subsidiaries (including the filing of any material litigation against the Company or any of its Subsidiaries or the existence of any dispute with any Person which involves a reasonable likelihood of such litigation being commenced), an
Officer’s Certificate specifying the nature and period of existence thereof and what actions the Company and its Subsidiaries have taken and propose to take with respect thereto; 
  
 (vii) within ten days after transmission thereof, copies of all financial statements, proxy statements,

directors file with respect to the Company, with the Securities and Exchange Commission or with any securities exchange on which any of its securities are then listed, and copies of all press releases and other statements made available generally by
the Company to the public concerning material developments in the Company’s and its Subsidiaries’ businesses; and 
  
 (viii) with reasonable promptness, such other information and financial data concerning the Company and its Subsidiaries as any Qualified
Holder may reasonably request. 
  
 Each of the financial statements referred to in
Sections 5(a)(i), (ii) and (iii) shall fairly present the financial condition and operations of the Company and its Subsidiaries as of the dates and for the periods stated therein, subject in the case of the unaudited financial statements to changes
resulting from normal year-end adjustments for recurring accruals (none of which would, alone or in the aggregate, be materially adverse to the financial condition, operating results, value, assets, operations or business prospects of the Company
and its Subsidiaries taken as a whole). 
  
 Notwithstanding the foregoing, the
provisions of this Section 5(a) shall cease to be effective so long as the Company (a) is subject to the periodic reporting requirements of the Securities Exchange Act and continues to comply with such requirements and (b) promptly provides to each
Qualified Holder all reports and other materials filed by the Company with the Securities and Exchange Commission pursuant to the periodic reporting requirements of the Securities Exchange Act. 
  
 Except as otherwise required by law or judicial order or decree or requested by any
governmental agency or authority, or as specified in the immediately following proviso, each Person entitled to receive information regarding the Company and its Subsidiaries under Sections 5(a) or (b) shall not disclose any such information to any
third party (other than such Person’s advisors or representatives); provided that such a Person may disclose such information (i) in connection with the actual or proposed sale or transfer of any Investor Equity, Preferred Stock, 

  

 10 

 
or Underlying Common Stock if the Person to whom the information is so disclosed agrees in writing to be bound by the provisions hereof, (ii) if such Person
is a partnership, limited liability company or corporation, to such Person’s partners, members and shareholders, as the case may be, in the ordinary course of its business, but upon notice to such other Persons of the confidential nature
thereof, (iii) as required by applicable law or by subpoena or other legal process, (iv) if such information is available to the public other than by reason of such Person’s breach of this provision or (v) to a nationally recognized statistical
rating organization in the ordinary course of business provided that such rating organization is advised of the confidential nature of such information. 
  
 For purposes of this Agreement, the Stock Purchase Agreement and the Registration Rights Agreement, all holdings of Investor Equity, Preferred Stock and Underlying Common
Stock by Persons who are Affiliates shall be aggregated for purposes of meeting any threshold tests under this Agreement, the Stock Purchase Agreement or the Registration Rights Agreement. 
  
 (b) Inspection of Property. To the extent not otherwise prohibited by
law or regulation, the Company shall permit any representatives designated by any Qualified Holder upon reasonable notice and during normal business hours and at such other times as any such Qualified Holder may reasonably request to (A) visit and
inspect any of the properties of the Company and its Subsidiaries, (B) examine the corporate and financial records of the Company and its Subsidiaries and make copies thereof or extracts therefrom and (C) discuss the affairs, finances and accounts
of any such corporations with the directors, officers, key employees and independent accountants of the Company and its Subsidiaries. The presentation of an executed copy of this Agreement (or photocopy thereof) by any Qualified Holder or
representative thereof to the Company’s independent accountants shall constitute the Company’s permission to its independent accountants to participate in discussions with such Persons notwithstanding the fact that such Qualified Holder is
not a party hereto. 
  
 (c) Restrictions. Prior to the
consummation of a Public Offering, the Company shall not so long as at least twenty percent (20%) of the shares of Preferred Stock outstanding immediately after consummation of the transactions contemplated by the Stock Purchase Agreement (as
proportionally adjusted for stock splits, stock dividends, and similar events after the date hereof) are then outstanding, without the prior written consent of the holders of a majority of Preferred Stock then outstanding, voting together as a
single class: 
  
 (i) make, or permit any of its
Subsidiaries to make, any loans or advances to, guarantees for the benefit of, or Investments in, any Person (other than a Wholly-Owned Subsidiary established under the laws of a jurisdiction of the United States or any of its territorial

upon the Transfer of any Restricted Securities (if such securities remain Restricted Securities after such Transfer) shall be stamped or otherwise imprinted with a legend in substantially the following form: 
  
 “The securities represented by this certificate are subject to a Second
Amended and Restated Shareholders Agreement dated as of December     , 2004, among the issuer of such securities (the “Issuer”) and the Issuer’s Shareholders, as amended and modified from time to time. A
copy of such Shareholders Agreement shall be furnished without charge by the Issuer to the holder hereof upon written request.” 
  
 The Company shall imprint such legend on certificates (if any) evidencing Restricted Securities outstanding as of the date hereof. The legend set forth above shall be
removed from the certificates (if any) evidencing any securities which cease to be Restricted Securities in accordance with the definition of such term herein. 
  

(e) Legend Removal. If any Restricted Securities become eligible for sale pursuant to Rule 144(k), the Company shall, upon the request of the

 (a) The Company and the Shareholders shall be entitled to enforce their

be an adequate remedy for any breach of the provisions of this Agreement and that the Company and any Shareholder may in its sole discretion apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive

redemption of Preferred Stock pursuant to Article Five, Section 8 of the Third Restated Certificate of Incorporation of the Company. 
  
 14. Amendment and Waiver. Except as otherwise set forth in this Section, the provisions of this Agreement may be amended, modified, or waived only
with the affirmative vote or prior written consent of a holders of a majority of the Underlying Common Stock then outstanding; provided that if any such amendment, modification, or waiver would materially and adversely affect any holder of
Common Stock (on an as converted basis) relative to its effect on the holders of the Common Stock (on an as converted basis) voting in favor of such amendment, modification, or waiver, such amendment, modification, or waiver shall also require the
written consent of the holders of a majority of such securities held by all holders so adversely affected. In addition to the foregoing: (v) Sections 4 and 14, and any definitions used directly or indirectly in such Sections may not be amended,
modified or waived without the affirmative vote or prior written consent of holders of each of a majority of the MDCP Equity then outstanding, the holders of a majority of the BV Equity then outstanding, and the holders of a majority of the VPVP
Equity then outstanding; (w) Sections 7(a)(ii)(B) and 7(a)(viii), and any definitions used directly or indirectly in such Sections may not be amended, modified or waived without the prior written consent of holders of a majority of the MDCP Equity

 28 

 
majority of the Preferred Stock outstanding at the time such action is taken, which majority shall include (i) the holders of a majority of the MDCP Equity,
(ii) the holders of a majority of the BV Equity, and (iii) the holders of a majority of the VPVP Equity. No course of dealing or the failure of any party to enforce any of the provisions of this Agreement shall be construed as a waiver of such
provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

interpretation of this Agreement and the exhibits and schedules hereto shall be governed by, and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters by

jurisdiction. In furtherance of the foregoing, the General Corporation Law of the State of Delaware or, if applicable, internal law of the State of California shall control the interpretation and construction of this Agreement (and all schedules and
exhibits hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply. 
  
 20. Counterparts. This Agreement may be executed in multiple counterparts, none of which need contain the signature

hereto or to any such agreement or instrument, each other party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a

party forever waives any such defense.

 EXHIBIT 10.2 
  
 THIRD AMENDED AND RESTATED 
 REGISTRATION RIGHTS AGREEMENT 
  
 THIS THIRD AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT (this “Agreement”) dated and effective as of December 29, 2004, is entered into by and among Cbeyond Communications, Inc., a Delaware
corporation (the “Company”) and the other signatories hereto. Capitalized terms used but not otherwise defined herein have the meanings set forth in Section 8 hereof. 
  
 R E C I T A L S 
  
 A. The Company has previously entered into an agreement to merge (the
“Merger”) with Cbeyond Investors, LLC (“Investors LLC”) pursuant to which Investors LLC merged with and into the Company immediately prior to the consummation of the initial closing under that certain Stock Purchase
Agreement, dated November 1, 2002, pursuant to which the Company issued shares of its Series B Participating Preferred Stock, par value $.01 per share (the “Series B Preferred Stock”). 
  
 B. In connection with the Merger, the Company and certain of its stockholders
entered into a Registration Rights Agreement, dated as of November 1, 2002 (as amended as of the date hereof, the “Existing Agreement”). 
  
 C. In connection with the issuance and sale of shares of Series C Participating Preferred Stock of the Company, par value $0.01 per share (the
“Series C Preferred Stock”, and, together with the Series B Preferred Stock, the “Preferred Stock”) pursuant to a that certain Stock Purchase Agreement by and among the Company and certain investors named therein
(the “Series C Investors”), dated as of the date hereof (the “Series C Stock Purchase Agreement”), the undersigned wish to, pursuant to Section 9.4 of the Existing Agreement, amend and restate the Existing Agreement
in its entirety as set forth herein effective upon the consummation of the closing of the purchase of Series C Preferred Stock under the Series C Stock Purchase Agreement. 
  
 NOW, THEREFORE, in consideration of the mutual promises made herein and other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree that the Existing Agreement is hereby amended and restated in its entirety as follows: 
  
 Section 1. Demand Registrations. 
  
 1.1 Requests for Registration. At any time prior to the
Company’s Initial Public Offering, (i) the holders of a majority of the Preferred Registrable Securities then outstanding may request registration under the Securities Act of all or any portion of their Registrable Securities on Form S-1 or any
similar long-form registration (a “Long-Form Registration”). After the Company’s Initial Public Offering, (i) the holders of a majority of the MDCP Registrable Securities then outstanding may request up to two (2) Long-Form
Registrations, (ii) the holders of a majority of the MSCP Registrable Securities then outstanding may request up to one (1) Long-Form Registration, (iii) the holders of a majority of the BV Registrable Securities then outstanding may request up to
two (2) Long-Form Registrations, (iv) 

 
the holders of a majority of the VPVP Registrable Securities then outstanding may request up to two (2) Long-Form Registrations, (v) the holders of a
majority of the Series C Registrable Securities then outstanding may request up to one (1) Long-Form Registration, and (vi) the holders of at least 10% of the Registrable Securities then outstanding may request registration under the Securities Act
of all or any portion of their Registrable Securities on Form S-3 or any similar short-form registration (“Short-Form Registrations”) if available; provided that the aggregate offering value of the Registrable Securities
requested to be registered in any registration under this Section 1.1 (any “Demand Registration”) must equal at least $50 million if the registration is the Company’s Initial Public Offering, at least $20 million in any other
Long-Form Registration, and at least $10 million in any Short-Form Registration. No Demand Registration shall be counted as a request for a Long-Form Registration by any holder pursuant to the previous sentence unless all shares requested to be
registered pursuant to the Demand Notice (as defined below) are actually registered. 
  
 All requests for Demand Registrations shall be made by giving written notice to the Company (the “Demand Notice”). Each Demand Notice shall specify the approximate number of Registrable Securities
requested to be registered and the anticipated per share price range for such offering. Within ten (10) days after receipt of any Demand Notice, the Company shall give written notice of such requested registration to all other holders of Registrable
Securities and, subject to the provisions of Section 1.4 below, shall include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within 15 days after the receipt of
the Company’s notice. 
  
 1.2 Expenses; Withdrawal.
The Company shall pay all Registration Expenses of all holders of Registrable Securities in all Demand Registrations. A registration shall not count as one of the permitted Long-Form Registrations until it has become effective; provided that
the Company shall in any event pay all Registration Expenses in connection with any registration initiated as a Demand Registration whether or not it has become effective and whether or not such registration has counted as one of the permitted
Long-Form Registrations. All Long-Form Registrations shall be underwritten registrations unless otherwise requested by the holders of a majority of the Registrable Securities requested to be included in the applicable Long-Form Registration.

  
 1.3 Short-Form Registrations. Demand Registrations
shall be Short-Form Registrations whenever the Company is permitted to use any applicable short form. After the Company has become subject to the reporting requirements of the Securities Exchange Act, the Company shall use its best efforts to make
Short-Form Registrations on Form S-3 (or any successor form) available for the sale of Registrable Securities. 
  
 1.4 Priority on Demand Registrations. The Company shall not include in any Demand Registration any securities which are not Registrable Securities
without the prior written consent of the holders of a majority of the Registrable Securities requested to be included in such registration. If a Demand Registration is an underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold
in an orderly manner in such offering within a price range acceptable to the holders of a majority of the Registrable Securities initially requesting registration, the Company shall include in such 

  

 2 

 
registration the number which can be so sold in the following order of priorities: (i) first, the Preferred Registrable Securities and the CISCO Warrant
Registrable Securities, pro rata among the holders of Preferred Registrable Securities and CISCO Warrant Registrable Securities on the basis of the number of such securities owned by each such holder, (ii) second, the Common Registrable Securities,
pro rata among the holders of Common Registrable Securities on the basis of the number of Common Registrable Securities owned by each such holder and (iii) third, other securities requested to be included in such registration; provided that,
to the extent (but only to the extent) the managing underwriters advise the Company in writing that in their opinion Registrable Securities held by holders who are also employees of the Company or any of its Subsidiaries cannot be included in such
offering without adversely effecting such offering, such Registrable Securities shall not be included in such offering. 
  
 1.5 Restrictions on Long-Form Registrations. The Company shall not be obligated to effect any Demand Registration which is a Long-Form Registration
within 180 days after the effective date of a previous Demand Registration which was a Long-Form Registration or a previous registration in which the holders of Registrable Securities were given piggyback rights pursuant to Section 2 and in which
there was no reduction in the number of Registrable Securities requested to be included. The Company may postpone for up to 180 days the filing or the effectiveness of a registration statement for a Demand Registration if the Company’s board of
directors (the “Board”) determines in its reasonable good faith judgment that such Demand Registration would reasonably be expected to have a material adverse effect on any proposal or plan by the Company or any of its Subsidiaries
to engage in any acquisition of assets (other than in the ordinary course of business) or any merger, consolidation, tender offer, reorganization or similar transaction or any other material offering or material transaction; provided that in
such event, the holders of Registrable Securities initially requesting such Demand Registration shall be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand
Registrations hereunder and the Company shall pay all Registration Expenses in connection with such withdrawn registration. The Company may delay a Demand Registration hereunder only once in any twelve-month period. 
  
 1.6 Selection of Underwriters. The Board shall select the investment
banker(s) and manager(s) to administer the offering. 
  
 1.7
Other Registration Rights. Except as provided in this Agreement, the Company shall not grant to any Persons the right to request the Company to register any equity securities of the Company, or any securities convertible or exchangeable into
or exercisable for such securities, without the prior written consent of the holders of a majority of the Preferred Registrable Securities then outstanding; provided that the Company may grant rights to other Persons to participate in
Piggyback Registrations so long as such rights are pari passu or subordinate to the rights of the holders of Registrable Securities with respect to such Piggyback Registrations. 
  
 Section 2. Piggyback Registrations. 
  
 2.1 Right to Piggyback. Whenever the Company proposes to register any of its securities under the Securities Act
(other than pursuant to a Demand Registration, an Initial Public Offering, a registration on Form S-4 or Form S-8 or any successor form thereto) and the 

  

 3 

 
registration form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”), the Company shall give
prompt written notice (in any event within three (3) business days after its receipt of notice of any exercise of demand registration rights other than under this Agreement) to all holders of Registrable Securities of its intention to effect such a
registration and shall include in such registration (subject to the exclusions pursuant to the priority provisions of Sections 2.3 and 2.4 below) all Registrable Securities with respect to which the Company has received written requests for
inclusion therein within twenty (20) days after the receipt of the Company’s notice. 
  
 2.2 Piggyback Expenses. The Registration Expenses of the holders of Registrable Securities shall be paid by the Company in all Piggyback Registrations. 
  
 2.3 Priority on Primary Registrations. If a Piggyback Registration is
an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be
sold in an orderly manner in such offering within a price range acceptable to the Company, the Company shall include in such registration (i) first, the securities the Company proposes to sell, (ii) second, the Preferred Registrable Securities and
the CISCO Warrant Registrable Securities, pro rata among the holders of Preferred Registrable Securities and CISCO Warrant Registrable Securities on the basis of the number of such securities owned by each such holder, (iii) third, the Common
Registrable Securities, pro rata among the holders of Common Registrable Securities on the basis of the number of Common Registrable Securities owned by each such holder and (iv) fourth, other securities requested to be included in such
registration; provided that, to the extent (but only to the extent) the managing underwriters advise the Company in writing that in their opinion Registrable Securities held by holders who are also employees of the Company or any of its
Subsidiaries cannot be included in such offering without adversely effecting such offering, such Registrable Securities shall not be included in such offering. 
  

2.4 Priority on Secondary Registrations. If a Piggyback Registration is an underwritten secondary registration on behalf of holders of the
Company’s securities, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number which can be sold in an orderly manner in such
offering within a price range acceptable to the holders initially requesting such registration, the Company shall include in such registration (i) first, the securities requested to be included therein by the holders requesting such registration,
the Preferred Registrable Securities and the CISCO Warrant Registrable Securities requested to be included in such registration, pro rata among the holders of any such securities on the basis of the number of securities so requested to be included
therein owned by each such holder, (ii) second, the Common Registrable Securities, pro rata among the holders of Common Registrable Securities on the basis of the number of Common Registrable Securities owned by each such holder and (iii) third,
other securities requested to be included in such registration; provided that, to the extent (but only to the extent) the managing underwriters advise the Company in writing that in their opinion Registrable Securities held by holders who are
also employees of the Company or any of its Subsidiaries cannot be included in such offering without adversely effecting such offering, such Registrable Securities shall not be included in such offering. 
  

 4 

 2.5 Selection of Underwriters. If any Piggyback Registration is an underwritten offering, the
selection of the investment banker(s) and manager(s) to administer such offering shall be approved by the Board. 
  
 2.6 Other Registrations. If the Company has previously filed a registration statement with respect to Registrable Securities pursuant to Section 1
or pursuant to this Section 2, and if such previous registration has not been withdrawn or abandoned, the Company shall not file or cause to be effected any other registration of any of its equity securities or securities convertible or exchangeable
into or exercisable for its equity securities under the Securities Act (except on Form S-8 or any successor form), whether on its own behalf or at the request of any holder or holders of such securities, until a period of at least 180 days has
elapsed from the effective date of such previous registration. 
  
 Section 2A. Registrations on Form S-3. 
  
 2A.1 If, at anytime on or after the date the Company first becomes eligible for use of Form S-3, (i) the Company shall receive a written request (specifying that it is being made pursuant to this Section 2A.1 from any holder or holders of
then outstanding Registrable Securities that the Company file a registration statement on Form S-3 (or any successor form to Form S-3 regardless of its designation) for a public offering of shares of the Registrable Securities the reasonably
anticipated aggregate price to the public of which would exceed Ten Million Dollars ($10,000,000), and (ii) the Company is a registrant entitled to use Form S-3 to register such shares, then the Company shall use its best efforts to cause such
shares to be registered on Form S-3 (or any successor form to Form S-3). The foregoing notwithstanding, if the Company shall furnish to the holders a certificate signed by the President of the Company stating that in the good faith judgment of the
Board of Directors it would be seriously detrimental to the Company or its stockholders for a registration statement to be filed in the near future and setting forth the reasons for such judgment, then the Company’s obligation to use its best
efforts to file a registration statement shall be deferred for a period not to exceed 90 days, provided, however, that the Company may not obtain a deferral pursuant to this clause more than once in any twelve month period. The Company shall not be
obligated to effect any such registration, pursuant to this Section 2A, if the Company has, within the twelve (12) month period preceding the date of such request, (i) already effected two registrations on Form S-3 for the holders pursuant to this
Section 2A or (ii) had a registration statement effective for at least one hundred eighty (180) days pursuant to this Section 2A. 
  
 2A.2 All expenses (excluding underwriters’ discounts and commissions) incurred in connection with a registration requested pursuant to Section 2A.1,
including, without limitation, all registration, qualification, printing and accounting fees, and fees and disbursements not to exceed Fifty Thousand Dollars ($50,000) of one counsel for the selling holder or holders and counsel to the Company shall
be borne by the Company. The holders’ rights to registration under this Section 2A are in addition to, and not in lieu of, their rights to registration under Sections 1 and 2 of this Agreement. Subject to the provision in Section 2A.1, the
holder’s right to request registration under this Section 2A shall be unlimited. 
  

 5 

 Section 3. Holdback Agreements. 
  
 3.1 Holders of Registrable Securities. Each holder of Registrable
Securities shall not effect any public sale or distribution (including sales pursuant to Rule 144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, during the seven days
prior to and (i) the 180-day period beginning on the effective date of the Initial Public Offering in the case of the Initial Public Offering and (ii) the 90-day period beginning on the effective date of any other underwritten Demand Registration or
any underwritten Piggyback Registration in which Registrable Securities of such holder are included (in each case, except as part of such underwritten registration), unless in each case the underwriters managing the registered public offering
otherwise agree, and, upon the request of the underwriters, each holder of Registrable Securities shall sign customary lock-up agreements for the benefit of the underwriters acknowledging their obligation to refrain from such action; provided, that
(i) all officers of the Company, directors of the Company and holders of at least 1% of the outstanding Registrable Securities of the Company enter into similar agreements and (ii) any exception to this Section shall be made available to all holders
of Registrable Securities. 
  
 3.2 The Company. The Company
(i) shall not effect any public sale or distribution of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the seven days prior to and during the 180-day period beginning on the
effective date of any underwritten Demand Registration or, except in the case of an underwritten primary registration, any underwritten Piggyback Registration (except as part of such underwritten registration or pursuant to registrations on Form S-8
or any successor form), unless the underwriters managing the registered public offering otherwise agree, and (ii) shall cause each holder of its Common Stock, or any securities convertible into or exchangeable or exercisable for Common Stock,
purchased from the Company at any time after November 1, 2002 (other than in a registered public offering or pursuant to Rule 144) to agree not to effect any public sale or distribution (including sales pursuant to Rule 144) of any such securities
during such period (except as part of such underwritten registration, if otherwise permitted), unless the underwriters managing the registered public offering otherwise agree. 
  
 Section 4. Registration Procedures. Whenever the holders of Registrable Securities have requested that any
Registrable Securities be registered pursuant to this Agreement, the Company shall use its best efforts to effect the registration and the sale of such Registrable Securities in accordance with the intended method of disposition thereof, and
pursuant thereto the Company shall as expeditiously as possible: 
  
 4.1 prepare and file with the Securities and Exchange Commission a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective (provided that before
filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall furnish to the counsel selected by the holders of a majority of the Registrable Securities covered by such registration statement copies of all
such documents proposed to be filed, which documents shall be subject to the review and comment of such counsel); 
  
 4.2 notify each holder of Registrable Securities of the effectiveness of each registration statement filed hereunder and prepare and file with the
Securities and Exchange Commission such amendments and supplements to such registration statement and the 

  

 6 

 
prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not more than 180 days (in the case
of a non-underwritten registration statement utilizing Rule 415 under the Securities Act) and otherwise so as to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such registration statement; 
  
 4.3 furnish to each seller of Registrable Securities such number of copies of such registration statement, each amendment and supplement thereto, the
prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

  
 4.4 use its best efforts to register or qualify such
Registrable Securities under such other securities or blue sky laws of such jurisdictions as any seller reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate
the disposition in such jurisdictions of the Registrable Securities owned by such seller (provided that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify
but for this Section 4.4, (ii) subject itself to taxation in any such jurisdiction or (iii) consent to general service of process in any such jurisdiction); 
  
 4.5 notify each seller of such Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities
Act, of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading, and, at the
request of any such seller, the Company shall prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not contain an untrue statement of a material
fact or omit to state any fact necessary to make the statements therein not misleading; 
  
 4.6 cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Company are then listed and, if not so listed, to be listed on the Nasdaq and, if listed on
the Nasdaq, use its best efforts to secure designation of all such Registrable Securities covered by such registration statement as a Nasdaq “national market system security” within the meaning of Rule 11Aa2-1 of the Securities and
Exchange Commission or, failing that, to secure Nasdaq authorization for such Registrable Securities and, without limiting the generality of the foregoing, to arrange for at least two market makers to register as such with respect to such
Registrable Securities with the NASD; 
  
 4.7 provide a transfer
agent and registrar for all such Registrable Securities not later than the effective date of such registration statement; 
  
 4.8 enter into such customary agreements (including underwriting agreements in customary form) and take all such other actions as the holders of a
majority of the Registrable Securities being sold or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including effecting a stock split or a combination of shares);

  

 7 

 4.9 make available for inspection by any seller of Registrable Securities, any underwriter participating
in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such seller or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and
cause the Company’s officers, directors, employees and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant or agent in connection with such registration statement;

  
 4.10 otherwise use its best efforts to comply with all
applicable rules and regulations of the Securities and Exchange Commission, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve months beginning with the first
day of the Company’s first full calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder; 
  
 4.11 permit any holder of Registrable Securities which holder, in its sole
and exclusive judgment, might be deemed to be an underwriter or a controlling person of the Company, to participate in the preparation of such registration or comparable statement and to require the insertion therein of material, furnished to the
Company in writing, which in the reasonable judgment of such holder and its counsel should be included; 
  
 4.12 in the event of the issuance of any stop order suspending the effectiveness of a registration statement, or of any order suspending or preventing the
use of any related prospectus or suspending the qualification of any common stock included in such registration statement for sale in any jurisdiction, the Company shall use its best efforts promptly to obtain the withdrawal of such order; and

  
 4.13 in an underwritten offering, obtain a cold comfort letter
from the Company’s independent public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the managing underwriter of such offering may reasonably request. 
  
 Section 5. Registration Expenses. 
  
 5.1 Expenses. All expenses incident to the Company’s performance
of or compliance with this Agreement, including without limitation all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, printing expenses, messenger and delivery expenses, fees and disbursements of
custodians, and fees and disbursements of counsel for the Company and the Company’s independent certified public accountants, underwriters (excluding discounts and commissions) and other Persons retained by the Company (all such expenses being
herein called “Registration Expenses”), shall be borne as provided in this Agreement, except that the Company shall, in any event, pay its internal expenses (including, without limitation, all salaries and expenses of its officers
and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on
which similar securities issued by the Company are then listed or on the Nasdaq. 
  

 8 

 5.2 Reimbursement of Counsel. In connection with each Demand Registration and each Piggyback
Registration, the Company shall reimburse the holders of Registrable Securities included in such registration for the reasonable fees and disbursements of one counsel chosen by the holders of a majority of the Preferred Registrable Securities
included in such registration. 
  
 5.3 Payment of Certain
Expenses by Holders of Registrable Securities. Underwriting discounts and commissions and transfer taxes relating to the Registrable Securities included in any registration hereunder, and all fees and expenses of counsel for any holder of
Registrable Securities (other than fees and expenses to be reimbursed by the Company as set forth in Section 5.2 above) shall be borne and paid by the holders of such Registrable Securities. 
  
 Section 6. Indemnification. 
  
 6.1 The Company agrees to indemnify, to the extent permitted by law, each
holder of Registrable Securities, its officers, directors, partners, managers (and, in the case of any holder that is a mutual fund, its investment advisor) and each Person that controls such holder (within the meaning of the Securities Act) against
all losses, claims, damages, liabilities and expenses caused by any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or
any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the
Company by such holder expressly for use therein or by such holder’s failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such holder with a sufficient
number of copies of the same. In connection with an underwritten offering, the Company shall indemnify such underwriters, their officers and directors and each Person who controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to the indemnification of the holders of Registrable Securities. 
  
 6.2 In connection with any registration statement in which a holder of Registrable Securities is participating, each such holder shall furnish to the
Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such registration statement or prospectus and, to the extent permitted by law, shall indemnify the Company, its directors and
officers and each Person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact contained in the
registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not
misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such holder; provided that the obligation to indemnify shall be individual, not joint and
several, for each holder and shall be limited to the net amount of proceeds received by such holder from the sale of Registrable Securities pursuant to such registration statement. 
  
 6.3 Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any
claim with respect to which it seeks 

  

 9 

 
indemnification (provided that the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder to the extent such
failure has not prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such
indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified
party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified
parties with respect to such claim. 
  
 6.4 The indemnification
provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, partner, manager or controlling Person of such indemnified party and
shall survive the transfer of securities. The Company also agrees to make such provisions, as are reasonably requested by any indemnified party, for contribution to such party in the event the Company’s indemnification is unavailable for any
reason. 
  
 Section 7. Participation in Underwritten
Registrations. No Person may participate in any registration hereunder which is underwritten unless such Person (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or
Persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements;
provided that no holder of Registrable Securities included in any underwritten registration shall be required to make any representations or warranties to the Company or the underwriters (other than representations and warranties regarding such
holder, its ownership of such Registrable Securities and such holder’s intended method of distribution) or to undertake any indemnification obligations to the Company with respect thereto, except as otherwise provided in Section 6.2 hereof, or
to the underwriters with respect thereto, except to the extent of the indemnification being given to the Company and its controlling persons in Section 6.2 hereof.

 9.2 Adjustments Affecting Registrable Securities. The Company shall not take any action, or permit any change to

 9.3 Remedies. Any Person having rights under any provision of this
Agreement shall be entitled to enforce such rights specifically, to recover damages caused by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. The parties hereto agree and acknowledge that
money damages may not be an adequate remedy for any breach of the provisions of this Agreement and that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction (without posting any 

  

 12 

 
bond or other security) for specific performance and for other injunctive relief in order to enforce or prevent violation of the provisions of this
Agreement. 
  
 9.4 Amendments and Waivers. Subject to the
provisions of Section 5A of the Shareholders Agreement, the provisions of this Agreement may be amended or waived only upon the prior written consent of the Company and the holders of a majority of Registrable Securities then outstanding; provided
that if any such amendment, modification or waiver would materially and adversely affect any holder of Registrable Securities relative to its effect on the holders of the Registrable Securities voting in favor of such amendment, modification or

 9.5 Successors and Assigns. All covenants and agreements in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the

Strict Construction. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a substantive part of this Agreement. Whenever required by the context, any pronoun used in this Agreement shall include the
corresponding masculine, feminine or neuter forms, and the singular forms of nouns, pronouns, and verbs shall include the plural and vice versa. Reference to any agreement, document, or instrument means such agreement, document, or instrument as
amended or otherwise modified from time to time in accordance with the terms thereof, and if applicable hereof. The use of the words “include” or “including” in this Agreement shall be by way of example rather than by limitation.
The use of the words “or,” “either” or “any” shall not be exclusive. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or
interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or 

  

 13 

 
burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement.

or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given when (a) delivered personally to the recipient, (b) telecopied to the recipient (with hard copy sent to the recipient by

Company’s records, or at such address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party. The Company’s address is:

the state in which the Company’s chief-executive office is located, the time period shall automatically be extended to the business day immediately following such Saturday, Sunday or legal holiday. 
  
 9.10 Governing Law. All issues and questions concerning the
construction, validity, enforcement and interpretation of this Agreement and the exhibits and schedules hereto shall be governed by, and construed in accordance with the General Corporation Law of the State of Delaware as to matters within the scope
thereof, and as to all other matters by the internal laws of the State of California, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of California or any other jurisdiction) that would cause
the application of the laws of any other jurisdiction. In furtherance of the foregoing, the General Corporation Law of the State of Delaware or, if applicable, internal law of the State of California shall control the interpretation and construction
of this Agreement (and all schedules and exhibits hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply. 
  
 9.11 Counterparts. This Agreement may be executed simultaneously in
two or more counterparts, any one of which need not contain the signatures of more than one party, but all such counterparts taken together shall constitute one and the same Agreement. 
  
 9.12 Delivery by Facsimile. This Agreement, the agreements referred to herein, and each other agreement or instrument
entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine, shall be treated in all manner and respects as an original
agreement or instrument and shall be considered to have the same binding legal effect as 

  

 14 

 
if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other
party hereto or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine to deliver a signature or the fact that any
signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the formation or enforceability of a contract and each such party forever waives any such defense. 
  
 9.13 Amendment and Restatement; Effectiveness. This Agreement amends
and restates in its entirety the Existing Agreement and shall be effective with respect to all parties to the Existing Agreement when executed and delivered by those parties required under Section 9.4 of the Existing Agreement even if this Agreement
is not executed and delivered by other Persons whose signature blocks appear on the signature pages hereto.
