The Purchaser Class A Common Stock issuable upon conversion of the shares of Purchaser Series B Stock issuable pursuant to this Agreement has been duly reserved for issuance, and upon issuance in accordance with the terms of the Restated Certificate, will be validly issued, fully paid and nonassessable and free of restrictions on transfer other than restrictions on transfer under the Transaction Documents, applicable federal and state securities laws and liens or encumbrances created by or imposed by a Purchaser. Based in part upon the representations of the Company and the Initial Selling Stockholders in Article 2 and Article 3, and subject to Section 4.5(b) below, the Purchaser Class A Common Stock issuable upon conversion of the shares of Purchaser Series B Stock issuable pursuant to this Agreement will be issued in compliance with all applicable federal and state securities laws. For accounting purposes, the Purchaser Series B Stock is classified as equity and not as debt.

(b) No “bad actor” disqualifying event described in Rule 506(d)(1)(i)-(viii) of the Securities Act (a “Disqualification Event”) is applicable to Purchaser or, to Purchaser’s knowledge, any Company Covered Person, except for a Disqualification Event as to which Rule 506(d)(2)(ii–iv) or (d)(3), is applicable.

4.6 Governmental Consents and Filings. Assuming the accuracy of the representations made by the Company and the Initial Selling Stockholders in Article 2 and Article 3, no consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of Purchaser in connection with the consummation of the transactions contemplated by this Agreement, except for any filings that may be required pursuant to Regulation D of the Securities Act, and applicable state securities laws, which to the extent required have been made or will be made in a timely manner.

4.7 Litigation. There is no claim, action, suit, proceeding, arbitration, complaint, charge or investigation pending or to Purchaser’s knowledge, currently threatened in writing (i) against Purchaser or any officer or director of Purchaser arising out of such officer’s or director’s employment or board relationship with Purchaser; (ii) to Purchaser’s knowledge, that questions the validity of the Transaction Documents or the right of Purchaser to enter into them, or to consummate the transactions

contemplated by the Transaction Documents; or (iii) to Purchaser’s knowledge, that would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect with respect to Purchaser. Neither Purchaser nor, to Purchaser’s knowledge, any of its officers or directors is a party or is named as subject to the provisions of any order, writ, injunction, judgment or decree of any court or government agency or instrumentality (in the case of officers or directors, such as would affect Purchaser). There is no action, suit, proceeding or investigation by Purchaser pending or which Purchaser intends to initiate. The foregoing includes, without limitation, actions, suits, proceedings or investigations pending or threatened in writing (or any basis therefor known to Purchaser) involving the prior employment of any of Purchaser’s employees, their services provided in connection with Purchaser’s business, any information or techniques allegedly proprietary to any of their former employers or their obligations under any agreements with prior employers.

4.8 Intellectual Property. Purchaser owns or possesses or believes it can acquire on commercially reasonable terms sufficient legal rights to all Purchaser Intellectual Property without any known conflict with, or infringement of, the rights of others. To Purchaser’s knowledge, no product or service marketed or sold (or proposed to be marketed or sold) by Purchaser violates or will violate any license or infringes or will infringe any intellectual property rights of any other party. Other than with respect to generally commercially available software products under standard end-user object code license agreements, there are no outstanding options, licenses, agreements, claims, encumbrances or shared ownership interests of any kind relating to Purchaser Intellectual Property, nor is Purchaser bound by or a party to any options, licenses or agreements of any kind with respect to the patents, trademarks, service marks, trade names, copyrights, trade secrets, licenses, information, proprietary rights and processes of any other Person. Purchaser has not received any communications alleging that Purchaser has violated, or by conducting its business, would violate any of the patents, trademarks, service marks, tradenames, copyrights, trade secrets, mask works or other proprietary rights or processes of any other Person. Purchaser has obtained and possesses valid licenses to use all of the software programs present on the computers and other software- enabled electronic devices that it owns or leases or that it has otherwise provided to its employees for their use in connection with Purchaser’s business. To Purchaser’s knowledge, it will not be necessary to use any inventions of any of its employees or consultants (or Persons it currently intends to hire) made prior to their employment by Purchaser. Each current and former employee and consultant has assigned to Purchaser all intellectual property rights he or she owns that are related to Purchaser’s business as now conducted and as presently proposed to be conducted. Section 4.8 of the Purchaser Disclosure Letter lists all Purchaser Intellectual Property that is registered with a governmental entity. Purchaser has not embedded any open source, copyleft or community source code in any of its products generally available or in development, including but not limited to any libraries or code licensed under any General Public License, Lesser General Public License or similar license arrangement in a manner that would require (or purport to require) the distribution of the source code of such software or prohibit (or purport to prohibit) Purchaser from charging for the distribution or use of the software or otherwise limit such software’s use for commercial purposes. For purposes of this Section 4.8, Purchaser shall be deemed to have knowledge of a patent right if Purchaser has actual knowledge of the patent right or would be found to be on notice of such patent right as determined by reference to United States patent laws.

4.9 Compliance with Other Instruments. Purchaser is not in violation or default (i) of any provisions of its Restated Certificate or Bylaws, (ii) in any material respect, of any instrument, judgment, order, writ or decree, or (iii) in any material respect, under any lease, agreement, contract or purchase order to which it is a party or by which it is bound that is required to be listed on the Purchaser Disclosure Letter, or (iv) to its knowledge, of any provision of federal or state statute, rule or regulation applicable to Purchaser, the violation of which would have a Material Adverse Effect with respect to Purchaser. The execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated by the Transaction Documents will not result in any such

violation or be in conflict with or constitute, with or without the passage of time and giving of notice, either (i) a material default under any such provision, instrument, judgment, order, writ, decree, contract or agreement; or (ii) an event which results in the creation of any material lien, charge or encumbrance upon any assets of Purchaser or the suspension, revocation, forfeiture, or nonrenewal of any material permit or license applicable to Purchaser.

4.10 Agreements; Actions.

(a) Except for the Transaction Documents, there are no agreements, understandings, instruments, contracts or proposed transactions to which Purchaser is a party or by which it is bound that involve: (i) obligations (contingent or otherwise) of, or payments to, Purchaser in excess of $250,000, (ii) the license of any patent, copyright, trademark, trade secret or other proprietary right to or from Purchaser other than licenses with respect to widely commercially available software products under standard end-user object code license agreements or standard customer terms of service and privacy policies for Internet sites, (iii) the grant of rights to manufacture, produce, assemble, license, market, or sell its products to any other Person that limit Purchaser’s exclusive right to develop, manufacture, assemble, distribute, market or sell its products, or (iv) indemnification by Purchaser with respect to infringements of proprietary rights other than standard customer or channel agreements (each, a “Purchaser Material Agreement”). Purchaser is not in material breach of or default under any Purchaser Material Agreement and, to Purchaser’s knowledge, there is no current claim or threat that Purchaser is or has been in material breach of or default under any Purchaser Material Agreement. Each Purchaser Material Agreement is in full force and effect and is enforceable by Purchaser in accordance with its respective terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization or others laws of general application relating to or affecting the enforcement of creditors’ rights generally or (ii) the effect of rules of law governing the availability of equitable remedies. To Purchaser’s knowledge, no other party to a Purchaser Material Agreement is in material default thereunder or in actual or anticipated material breach thereof.

(b) Purchaser has not (i) declared or paid any dividends, or authorized or made any distribution upon or with respect to any class or series of its capital stock, (ii) incurred any indebtedness for money borrowed or incurred any other liabilities individually in excess of $150,000 or in excess of $300,000 in the aggregate, (iii) made any loans or advances to any Person, other than ordinary advances for travel expenses, or (iv) sold, exchanged or otherwise disposed of any of its assets or rights, other than the sale of its inventory in the ordinary course of business. For the purposes of (a) and (b) of this Section 4.10, all indebtedness, liabilities, agreements, understandings, instruments, contracts and proposed transactions involving the same Person (including Persons Purchaser has reason to believe are affiliated with each other) shall be aggregated for the purpose of meeting the individual minimum dollar amounts of such subsection.

(c) Purchaser is not a guarantor or indemnitor of any indebtedness of any other Person.

4.11 Certain Transactions.

(a) Other than (i) standard employee benefits generally made available to all employees, (ii) standard director and officer indemnification agreements approved by the Purchaser’s board of directors, and (iii) the purchase of shares of Purchaser’s capital stock and the issuance of options to purchase shares of Purchaser Common Stock, in each instance, approved in the written minutes of the Purchaser’s board of directors, there are no agreements, understandings or proposed transactions between Purchaser and any of its officers, directors or consultants, or any Affiliate thereof.

(b) Purchaser is not indebted, directly or indirectly, to any of its directors, officers or employees or to their respective spouses or children or to any Affiliate of any of the foregoing, other than in connection with expenses or advances of expenses incurred in the ordinary course of business or employee relocation expenses and for other customary employee benefits made generally available to all employees. None of Purchaser’s directors or officers, or any members of their immediate families, or any Affiliate of the foregoing are, directly or indirectly, indebted to Purchaser or, to Purchaser’s knowledge, have any (i) material commercial, industrial, banking, consulting, legal, accounting, charitable or familial relationship with any of Purchaser’s customers, suppliers, service providers, joint venture partners, licensees and competitors, (ii) direct or indirect ownership interest in any firm or corporation with which Purchaser is affiliated or with which Purchaser has a business relationship, or any firm or corporation which competes with Purchaser except that directors, officers, employees or stockholders of Purchaser may own stock in (but not exceeding two percent (2%) of the outstanding capital stock of) publicly traded companies that may compete with Purchaser; or (iii) material financial interest in any material contract with Purchaser.

4.12 Rights of Registration and Voting Rights. Except as provided in the Purchaser Investors’ Rights Agreement, Purchaser is not under any obligation to register under the Securities Act any of its currently outstanding securities or any securities issuable upon exercise or conversion of its currently outstanding securities. To Purchaser’s knowledge, except as contemplated in the Purchaser Voting Agreement, no stockholder of Purchaser has entered into any agreements with respect to the voting of capital shares of Purchaser.

4.13 Property. The property and assets that Purchaser owns are free and clear of all mortgages, deeds of trust, liens, loans and encumbrances, except for statutory liens for the payment of current Taxes that are not yet due and payable and encumbrances and liens that arise in the ordinary course of business and do not materially impair Purchaser’s ownership or use of such property or assets. With respect to the property and assets it leases, Purchaser is in compliance with such leases and, to its knowledge, holds a valid leasehold interest free of any liens, claims or encumbrances other than those of the lessors of such property or assets. Purchaser does not own any real property.

4.14 Financial Statements. Purchaser has made available to each Company Securityholder its unaudited financial statements (including balance sheet, income statement and statement of cash flows) as of March 31, 2017 and for the three-month period then ended (collectively, the “Purchaser Financial Statements”). The Purchaser Financial Statements have been prepared in accordance with generally accepted accounting principles applied on a consistent basis throughout the periods indicated, except that the unaudited Purchaser Financial Statements may not contain all footnotes required by generally accepted accounting principles. The Purchaser Financial Statements fairly present in all material respects the financial condition and operating results of Purchaser as of the dates, and for the periods, indicated therein. Except as set forth in the Purchaser Financial Statements, Purchaser has no material liabilities or obligations, contingent or otherwise, other than (a) liabilities incurred in the ordinary course of business subsequent to March 31, 2017 that are not material, individually or in the aggregate, and in each case which liabilities and obligations do not exceed $150,000 individually or $300,000 in the aggregate, (b) obligations under contracts and commitments incurred in the ordinary course of business and (c) liabilities and obligations of a type or nature not required under generally accepted accounting principles to be reflected in the Purchaser Financial Statements.

4.15 Changes. Since March 31, 2017, there has not been:

(b) any damage, destruction or loss, whether or not covered by insurance, that would have a Material Adverse Effect with respect to Purchaser;

(c) any waiver or compromise by Purchaser of a valuable right or of a material debt owed to it;

(d) any satisfaction or discharge of any lien, claim, or encumbrance or payment of any obligation by Purchaser, except in the ordinary course of business and the satisfaction or discharge of which would not have a Material Adverse Effect with respect to Purchaser;

(f) any material change in any compensation arrangement or agreement with any employee, officer, director or stockholder;

(h) any mortgage, pledge, transfer of a security interest in, or lien, created by Purchaser, with respect to any of its material properties or assets, except liens for Taxes not yet due and payable and liens that arise in the ordinary course of business and do not materially impair Purchaser’s ownership or use of such property or assets;

(i) any loans or guarantees made by Purchaser to or for the benefit of its employees, officers or directors, or any members of their immediate families, other than travel advances and other advances made in the ordinary course of its business;

(l) receipt of notice that there has been a loss of, or material order cancellation by, any major customer of Purchaser;

(m) to Purchaser’s knowledge, any other event or condition of any character, other than events affecting the economy or Purchaser’s industry generally, that could reasonably be expected to result in a Material Adverse Effect with respect to Purchaser; or

(b) To Purchaser’s knowledge, none of its employees is obligated under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any

judgment, decree or order of any court or administrative agency, that would materially interfere with such employee’s ability to promote the interest of Purchaser or that would conflict with Purchaser’s business. Neither the execution or delivery of the Transaction Documents, nor the carrying on of Purchaser’s business by the employees of Purchaser, nor the conduct of Purchaser’s business as now conducted and as presently proposed to be conducted, will, to Purchaser’s knowledge, conflict with or result in a breach of the terms, conditions, or provisions of, or constitute a default under, any contract, covenant or instrument under which any such employee is now obligated.

(c) Purchaser is not delinquent in payments to any of its employees, consultants, or independent contractors for any wages, salaries, commissions, bonuses, or other direct compensation for any service performed for it to the date hereof or amounts required to be reimbursed to such employees, consultants or independent contractors. Purchaser has complied in all material respects with all applicable state and federal equal employment opportunity laws and with other laws related to employment, including those related to wages, hours, worker classification and collective bargaining.

(a) At the Closing, Purchaser shall withhold the Holdback Amount from the Contingent Consideration payable and/or issuable to the Selling Securityholders pursuant to Section 1.5(a) (the aggregate amount of cash so held by Purchaser from time to time, the “Holdback Fund”). The Holdback Fund shall constitute partial security for the benefit of Purchaser (on behalf of itself or any other Indemnified Person) with respect to any Indemnifiable Damages pursuant to the indemnification obligations of the Selling Securityholders under this Article IX. Subject to Section 9.4, Purchaser shall hold the Holdback Fund until 11:59 p.m. local time on the date (the “Holdback Release Date”) that is 12 months after the Closing (the “Holdback Period”). The Selling Securityholders shall not receive interest or other earnings on the cash in the Holdback Fund. Neither the Holdback Fund (including any portion thereof) nor any beneficial interest therein may be pledged, subjected to any Encumbrance, sold, assigned or transferred by any Selling Securityholder or be taken or reached by any legal or equitable process in satisfaction of any debt or other Liability of any Selling Securityholder, in each case prior to the distribution of the Holdback Fund to any Selling Securityholder in accordance with Section 9.1(b), except that each Selling Securityholder shall be entitled to assign such Selling Securityholder’s rights to such Selling Securityholder’s Pro Rata Share of the Holdback Fund by will, by the laws of intestacy or by other operation of law.

9.2 Indemnification.

(a) Subject to the limitations set forth in this Article IX, from and after the Closing, each Selling Securityholder shall severally but not jointly, and in accordance with its Pro Rata Share, indemnify and hold harmless Purchaser and the Company and their respective officers, directors, agents

and employees and each Person, if any, who controls or may control Purchaser within the meaning of the Securities Act (each, an “Indemnified Person”) from and against, and shall compensate and reimburse each Indemnified Person for, any and all losses, Liabilities, damages, claims, fees, lost profits, Taxes, reductions in value, interest, costs and expenses, including costs of investigation, enforcement and defense and reasonable fees and expenses of counsel, experts and other professionals, directly or indirectly, whether or not due to a Third-Party Claim (collectively, “Indemnifiable Damages”), arising out of, resulting from or in connection with:

(i) any failure of any representation or warranty made by the Company in Article II (as modified by the Company Disclosure Letter (including any exhibit or schedule to the Company Disclosure Letter)) to be true and correct (A) as of the Agreement Date (except in the case of representations and warranties that by their terms speak only as of a specified date or dates, which representations and warranties shall be true and correct as of such date or dates) or (B) as of the Closing Date as though such representation or warranty were made as of the Closing Date (except in the case of representations and warranties that by their terms speak only as of a specific date or dates, which representations and warranties shall be true and correct as of such date or dates);

(ii) any failure of any certification, representation or warranty made by the Company in any certificate (other than the Spreadsheet) delivered to Purchaser pursuant to this Agreement to be true and correct as of the date such certificate is delivered to Purchaser;

(iii) any unpaid Pre-Closing Taxes;

(iv) any breach of, or default in connection with, any of the covenants, agreements or obligations made by the Company herein;

(v) any inaccuracies in the Spreadsheet and any unpaid Transaction Expenses;

(vi) any claims by (A) any then-current or former holder or alleged then- current or former holder of any Equity Interests of the Company (including any predecessors), arising out of, resulting from or in connection with (I) the Transactions or this Agreement, including the allocation of the Total Consideration or any portion thereof, or (II) such Person’s status or alleged status as a holder of Equity Interests of any Group Company (including any predecessors) at any time at or prior to the Closing, whether for breach of fiduciary duty or otherwise, (B) any Person to the effect that such Person is entitled to any Equity Interest of Purchaser or any Group Company or any payment in connection with the Transactions other than as specifically set forth on the Spreadsheet or (C) any Person with respect to any Company Option Plan or any other plan, policy or Contract providing for compensation to any Person in the form of Equity Interests; and

(vii) any Fraud, intentional misrepresentation or willful misconduct by or on behalf of the Company.

(b) From and after the Closing, each Selling Securityholder shall severally but not jointly, solely as to himself, herself or itself, indemnify and hold harmless the Indemnified Persons from and against any and all Indemnifiable Damages arising out of, resulting from or in connection with (i) any failure of any representation or warranty made by such Selling Securityholder in Article III or in a Joinder Agreement to be true and correct as of the Agreement Date or as of the Closing Date as though such representation or warranty were made as of the Closing Date (except in the case of representations and warranties that by their terms speak only as of a specific date or dates, which representations and warranties shall be true and correct as of such date or dates), (ii) any failure of any certification,

representation or warranty made by such Selling Securityholder in any certificate delivered to Purchaser pursuant to this Agreement to be true and correct as of the date such certificate is delivered to Purchaser, (iii) any breach of or default in connection with any of the covenants, agreements or obligations made by such Selling Securityholder herein and (iv) any Fraud, intentional misrepresentation or willful misconduct by such Selling Securityholder. The obligations of a Selling Securityholder under this Section 9.2(b) may be satisfied, at Purchaser’s sole discretion, from the amount otherwise distributable to such Selling Securityholder from the Holdback Fund or directly from such Selling Securityholder.

(c) Materiality standards and qualifications by reference to the defined term “Material Adverse Effect” in any representation, warranty, covenant, agreement or obligation shall not be taken into account in determining the amount of any Indemnifiable Damages with respect to an inaccuracy in such representation or warranty, or a breach of such covenant, agreement or obligation.

(d) From and after the Closing, the rights to indemnification, compensation and reimbursement set forth in Article IX shall be the sole and exclusive monetary remedy of the Indemnified Persons for claims regarding the subject matter of this Agreement.

9.3 Indemnifiable Damage Threshold; Other Limitations.

(a) Notwithstanding anything to the contrary contained herein, no Indemnified Person may make a claim against the Holdback Fund in respect of any claim for Indemnifiable Damages arising out of, resulting from or in connection with the matters listed in clauses (i), (ii) or (iii) of Section 9.2(a) (other than claims arising out of, resulting from or in connection with (i) Fraud, intentional misrepresentation or willful misconduct by or on behalf of the Company or by such Selling Stockholder, or (ii) any failure of any of the Special Representations to be true and correct as aforesaid) unless and until a Claim Certificate (together with any other delivered Claim Certificates) describing Indemnifiable Damages for claims other than those set forth in clauses (i) and (ii) in an aggregate amount greater than $300,000 (the “Basket”) has been delivered, in which case the Indemnified Person may make claims for indemnification, compensation and reimbursement and may receive cash from the Holdback Fund for all Indemnifiable Damages (including the amount of the Basket), subject to the limitations set forth in this Article IX. The Basket shall not apply to any other Indemnifiable Damages or claims therefor.

(b) If the Stock Purchase is consummated, recovery from the Holdback Fund shall constitute the sole and exclusive remedy for the indemnity obligations of each Selling Securityholder under this Agreement for Indemnifiable Damages (and not specific performance or other equitable remedies) arising out of, resulting from or in connection with the matters listed in clauses (i), (ii) or (iii) of Section 9.2(a), except (i) in the case of Fraud, intentional misrepresentation or willful misconduct by or on behalf of the Company or such Selling Securityholder and (ii) any failure of any of the representations and warranties made by (A) the Company in Section 2.1(a)-(b) (Organization, Standing, Power and Subsidiaries), Section 2.2 (Capital Structure), or Section 2.3(a) and Section 2.3(b)(i) and (ii)(A) (Authority; Non-contravention) or (B) the Company in any certificate delivered to Purchaser pursuant to this Agreement that are within the scope of those covered by the foregoing Sections (collectively, the “Special Representations”) to be true and correct as aforesaid.

(c) In the case of any claims for Indemnifiable Damages arising out of, resulting from or in connection with (1) the failure of any of the Special Representations to be true and correct as aforesaid, (2) the matters listed in clauses (iv) through (vii) of Section 9.2(a) or (3) the matters listed in Section 9.2(b) (clauses (1), (2) and (3) collectively, “Special Claims”), after Indemnified Persons have exhausted or made claims upon all amounts of cash held in the Holdback Fund (after taking into account all other claims for indemnification, compensation and reimbursement from the Holdback Fund made by Indemnified Persons), or following the Holdback Release Date, each Selling Securityholder shall have

Liability for such Selling Securityholder’s Pro Rata Share of the amount of any Indemnifiable Damages resulting therefrom. Notwithstanding anything to the contrary contained herein, (i) the total Liability of a Selling Securityholder for Special Claims shall be limited to the aggregate amount of cash and the aggregate number of shares of Purchaser Series B Stock that has been paid or issued, respectively, to such Selling Securityholder pursuant to Sections 1.5(a)-(c) (the “Securityholder’s Consideration”) and (ii) any limitation of Liability in this Section 9.3(c) shall not apply in the case of a claim for Fraud, intentional misrepresentation or willful misconduct against a Selling Securityholder who commits such Fraud, intentional misrepresentation or willful misconduct. To the extent of any such Liability of a Selling Securityholder following exhaustion or release of all amounts of cash held in the Holdback Fund, such Selling Securityholder may elect to satisfy such Liability either (x) in cash or (y) to the extent applicable, with a combination of cash and Purchaser Series B Stock (which combination is proportionate to such Securityholder’s Consideration), with such Purchaser Series B Stock valued, for the purposes of this Article IX, at the Purchaser Series B Stock Price.

(d) Notwithstanding anything to the contrary contained herein, the amounts that an Indemnified Person recovers from the Holdback Fund pursuant to Special Claims shall not reduce the amount that an Indemnified Person may recover with respect to claims that are not Special Claims. By way of illustration and not limitation, assuming there are no other claims for indemnification, compensation or reimbursement, in the event that Indemnifiable Damages resulting from a Special Claim are first satisfied from the Holdback Fund and such recovery fully depletes the Holdback Fund, the maximum amount recoverable by an Indemnified Person pursuant to a subsequent claim that is not a Special Claim shall continue to be the full dollar value of the Holdback Fund irrespective of the fact that the Holdback Fund was used to satisfy such Special Claim, such that the amount recoverable for such two claims would be the same regardless of the chronological order in which they were made.

(e) Notwithstanding anything to the contrary contained herein, (i) no Selling Securityholder shall have any right of indemnification, compensation, reimbursement, contribution or right of advancement from Purchaser, the Company or any other Indemnified Person (based upon such Selling Securityholder’s position as an officer, director, employee or agent of the Company or otherwise) with respect to any Indemnifiable Damages claimed by any Indemnified Person or any right of subrogation against the Company with respect to any indemnification, compensation or reimbursement of an Indemnified Person by reason of any of the matters set forth in Section 9.2(a), (ii) the rights and remedies of the Indemnified Persons after the Closing shall not be limited by (x) any investigation by or on behalf of, or disclosure to (other than in the Company Disclosure Letter with respect to clauses (i) and (vi) of Section 9.2(a)), any Indemnified Person at or prior to the Closing regarding any failure, breach or other event or circumstance or (y) any waiver of any condition to the Closing related thereto, (iii) if an Indemnified Person’s claim under this Article IX may be properly characterized in multiple ways in accordance with this Article IX such that such claim may or may not be subject to different limitations depending on such characterization, then such Indemnified Person shall have the right to characterize such claim in a manner that maximizes the recovery and time to assert such claim permitted in accordance with this Article IX and (iv) no Selling Securityholder shall be liable for the breach of any representation, warranty or covenant of another Selling Securityholder or any Fraud, intentional misrepresentation or willful misconduct by or on behalf of any Person other than the Company or such Selling Securityholder; provided that nothing herein shall limit the Liability of a Selling Securityholder for any Fraud, intentional misrepresentation or willful misconduct by such Selling Securityholder.

(f) All Indemnifiable Damages shall be calculated net of the amount of any actual recoveries actually received by an Indemnified Person prior to the Holdback Release Date under any existing insurance policies and contractual indemnification or contribution provisions (in each case, calculated net of any actual collection costs and reserves, expenses, deductibles or premium adjustments or retrospectively rated premiums (as determined in good faith by an Indemnified Person) incurred or

paid to procure such recoveries) in respect of any Indemnifiable Damages suffered, paid, sustained or incurred by any Indemnified Person; provided that no Indemnified Person shall have any obligation to seek to obtain or continue to pursue any such recoveries.

9.4 Period for Claims. Except as otherwise set forth in this Section 9.4, the period (the “Claims Period”) during which claims may be made (a) against the Holdback Fund for Indemnifiable Damages arising out of, resulting from or in connection with the matters listed in clauses (i), (ii) and (iii) of Section 9.2(a) (other than with respect to any of the Special Representations) shall commence at the Closing and terminate at 11:59 p.m. local time on the Holdback Release Date and (b) for Indemnifiable Damages arising out of, resulting from or in connection with all other matters, including Special Claims, shall commence at the Closing and terminate at 11:59 p.m. local time on the date that is the expiration of the applicable statute of limitations. Notwithstanding anything to the contrary contained herein, the Claims Period for claims for Indemnifiable Damages arising out of, resulting from or in connection with Fraud, intentional misrepresentation or willful misconduct shall not be limited.

9.5 Claims.

(a) From time to time during the Claims Period, Purchaser may deliver to the Equityholders’ Representative one or more certificates signed by any officer of Purchaser (each, a “Claim Certificate”):

(i) stating that an Indemnified Person has incurred, paid, reserved or accrued, or in good faith believes that it may incur, pay, reserve or accrue, Indemnifiable Damages (or that with respect to any Tax matters, that any Tax Authority may raise such matter in audit of Purchaser or its subsidiaries, that could give rise to Indemnifiable Damages);

(ii) stating the amount of such Indemnifiable Damages (which, in the case of Indemnifiable Damages not yet incurred, paid, reserved or accrued, may be the maximum amount believed by Purchaser in good faith to be incurred, paid, reserved, accrued or demanded by a third party); and

(iii) specifying in reasonable detail (based upon the information then possessed by Purchaser) the individual items of such Indemnifiable Damages included in the amount so stated and the nature of the claim to which such Indemnifiable Damages are related.

(b) Such Claim Certificate (i) need only specify such information to the knowledge of such officer of Purchaser as of the date thereof, (ii) shall not limit any of the rights or remedies of any Indemnified Person with respect to the underlying facts and circumstances specifically set forth in such Claim Certificate and (iii) may be updated and amended from time to time by Purchaser by delivering any updated or amended Claim Certificate, so long as the delivery of the original Claim Certificate is made within the applicable Claims Period and such update or amendment relates to the underlying facts and circumstances specifically set forth in such original Claims Certificate; provided that all claims for Indemnifiable Damages properly set forth in a Claim Certificate or any update or amendment thereto shall remain outstanding until such claims have been resolved or satisfied, notwithstanding the expiration of such Claims Period. No delay in providing such Claim Certificate within the applicable Claims Period shall affect an Indemnified Person’s rights hereunder, unless (and then only to the extent that) the Equityholders’ Representative or the Selling Securityholders are prejudiced thereby.

9.6 Resolution of Objections to Claims.

(a) If the Equityholders’ Representative does not contest, by written notice to

Purchaser, any claim or claims by Purchaser made in any Claim Certificate within the 30-day period following receipt of the Claim Certificate, then the Purchaser shall reclaim an amount of cash from the Holdback Fund having a total value equal to the amount of any Indemnifiable Damages corresponding to such claim or claims as set forth in such Claim Certificate.

(b) If the Equityholders’ Representative objects in writing to any claim or claims by Purchaser made in any Claim Certificate within the 30-day period set forth in Section 9.6(a), Purchaser and the Equityholders’ Representative shall attempt in good faith for 60 days after Purchaser’s receipt of such written objection to resolve such objection. If Purchaser and the Equityholders’ Representative shall so agree, a memorandum setting forth such agreement shall be prepared and signed by both Purchaser and the Equityholders’ Representative. Purchaser shall be entitled to conclusively rely on any such memorandum and Purchaser shall reclaim an amount of cash from the Holdback Fund in accordance with the terms of such memorandum.

(c) If no such agreement can be reached during the 60-day period for good faith negotiation set forth in Section 9.6(b), but in any event upon the expiration of such 60-day period, either Purchaser or the Equityholders’ Representative may bring an arbitration in accordance with the terms of Section 10.12 to resolve the matter. The decision of the arbitral tribunal as to the validity and amount of any claim in such Claim Certificate shall be non-appealable, binding and conclusive upon the parties hereto and the Selling Securityholders, and Purchaser shall be entitled to act in accordance with such decisions and Purchaser shall reclaim an amount of cash from the Holdback Fund in accordance therewith.

(d) Judgment upon any determination of an arbitral tribunal may be entered in any court having jurisdiction. For purposes of this Section 9.6(d), in any suit hereunder in which any claim or the amount thereof stated in the Claim Certificate is at issue, Purchaser shall be deemed to be the prevailing party unless the arbitral tribunal determines in favor of the Equityholders’ Representative (on behalf of the Selling Securityholders) with respect to more than one-half of the amount in dispute, in which case the Selling Securityholders shall be deemed to be the prevailing party. The non-prevailing party to an arbitration shall pay its own fees and expenses and the fees and expenses of the prevailing party, including attorneys’ fees and costs, reasonably incurred in connection with such suit.

(e) Any portion of the Holdback Fund held following the Holdback Release Date with respect to a pending but unresolved claim for indemnification that is not awarded to Purchaser upon the resolution of such claim shall be distributed to the Selling Securityholders within five Business Days following resolution of such claim and in accordance with each such Selling Securityholder’s Pro Rata Share of such portion of the Holdback Fund.

(a) At the Closing, Shareholder Representative Services LLC shall be constituted and appointed as the Equityholders’ Representative. The Equityholders’ Representative shall be the representative, agent and attorney-in-fact for and on behalf of the Selling Securityholders for all purposes in connection with this Agreement and the agreements ancillary hereto, including to: (i) execute, as the Equityholders’ Representative, this Agreement and any agreement or instrument entered into or delivered in connection with the Transactions, (ii) give and receive notices, instructions and communications permitted or required under this Agreement, or any other agreement, document or instrument entered into or executed in connection herewith, for and on behalf of any Selling Securityholder, to or from Purchaser (on behalf of itself or any other Indemnified Person) relating to this Agreement or any of the Transactions and any other matters contemplated by this Agreement or by such other agreement, document or instrument (except to the extent that this Agreement expressly contemplates that any such notice or

communication shall be given or received by each Selling Securityholder individually), (iii) review, negotiate and agree to and authorize Purchaser to reclaim an amount of cash from the Holdback Fund in satisfaction of claims asserted by Purchaser (on behalf of itself or any other Indemnified Person, including by not objecting to such claims) pursuant to this Article IX, (iv) object to such claims pursuant to Section 9.6, (v) consent or agree to, negotiate, enter into, or, if applicable, contest, prosecute or defend, settlements and compromises of, and demand arbitration and comply with Orders of courts and awards of arbitrators with respect to, such claims, resolve any such claims, take any actions in connection with the resolution of any dispute relating hereto or to the Transactions by arbitration, settlement or otherwise, and take or forego any or all actions permitted or required of any Selling Securityholder or necessary in the judgment of the Equityholders’ Representative for the accomplishment of the foregoing and all of the other terms, conditions and limitations of this Agreement, (vi) consult with legal counsel, independent public accountants and other experts selected by it, solely at the cost and expense of the Selling Securityholders, (vii) consent or agree to any amendment to this Agreement or to waive any terms and conditions of this Agreement providing rights or benefits to the Selling Securityholders (other than with respect to the payment and issuance of the Total Consideration payable or issuable pursuant to Section 1.5(a) and Section 1.5(c) less the Holdback Amount) in accordance with the terms hereof and in the manner provided herein, (viii) take all actions necessary or appropriate in the judgment of the Equityholders’ Representative for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any Person under any circumstance and (ix) utilize the Expense Fund in connection with any of the foregoing. Purchaser and its Affiliates (including after the Closing, the Company) shall be entitled to rely on the appointment of Shareholder Representative Services LLC as the Equityholders’ Representative and treat such Equityholders’ Representative as the duly appointed attorney-in-fact of each Selling Securityholder and as having the duties, power and authority provided for in this Section 9.7. The Selling Securityholders shall be bound by all actions taken and documents executed by the Equityholders’ Representative in connection with this Article IX, and Purchaser and other Indemnified Persons shall be entitled to rely exclusively on any action or decision of the Equityholders’ Representative. The Person serving as the Equityholders’ Representative may be removed or replaced from time to time, or if such Person resigns from its position as the Equityholders’ Representative, then a successor may be appointed, by the holders of a majority in interest of the aggregate amount of cash then held in the Holdback Fund (or, in the event that there is no cash then held in the Holdback Fund by the Selling Securityholders collectively having a Pro Rata Share greater than 50%) upon not less than 30 days’ prior written notice to Purchaser. No bond shall be required of the Equityholders’ Representative.

(b) The Equityholders’ Representative shall not be liable to any Selling Securityholder for any act done or omitted hereunder as the Equityholders’ Representative while acting in good faith (and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith) and without gross negligence or willful misconduct provided, that notwithstanding the definition of “willful misconduct” set forth in Exhibit B, the term “willful misconduct” as used in each instance in this Section 9.7 (and in Section 1.6(c)) shall not have the meaning given to it in Exhibit B, but instead shall have the meaning given such term under the applicable laws of the State of Delaware without reference to the definition in Exhibit B. The Selling Securityholders shall severally (based on each Selling Securityholder’s Pro Rata Share compared to the aggregate of the Pro Rata Shares of all Selling Securityholders) but not jointly indemnify the Equityholders’ Representative and hold it harmless against any and all losses, liabilities, damages, claims, penalties, fines, forfeitures, actions, fees, costs and expenses (including the fees and expenses of counsel and experts and their staffs and all expense of document location, duplication and shipment) (collectively, “Representative Losses”) in an amount not to exceed the portion of the Total Consideration actually paid to each such Selling Securityholder arising out of or in connection with the Equityholders’ Representative’s execution and performance of this Agreement and any agreements ancillary hereto, in each case as such Representative Loss is suffered or incurred; provided, that in the event that any such Representative Loss is finally adjudicated to have been directly caused by the gross negligence or willful misconduct of the Equityholders’ Representative, the

Equityholders’ Representative will reimburse the Selling Securityholders the amount of such indemnified Representative Loss to the extent attributable to such gross negligence or willful misconduct. If not paid directly to the Equityholders’ Representative by the Selling Securityholders, any such Representative Losses may be recovered by the Equityholders’ Representative from (i) the funds in the Expense Fund, (ii) the amounts in the Holdback Fund at such time as remaining amounts would otherwise be distributable to the Selling Securityholders, and (iii) from any other future amounts that become payable to the Selling Securityholders under the terms of this Agreement at such time as any such amounts would otherwise be distributable to the Selling Securityholders; provided, that while this section allows the Equityholders’ Representative to be paid from the aforementioned sources of funds, this does not relieve the Selling Securityholders from their obligation to promptly pay such Representative Losses as they are suffered or incurred, nor does it prevent the Equityholders’ Representative from seeking any remedies available to it at law or otherwise. In no event will the Equityholders’ Representative be required to advance its own funds on behalf of the Selling Securityholders or otherwise. Notwithstanding anything in this Agreement to the contrary, any restrictions or limitations on liability or indemnification obligations of the Selling Securityholders set forth elsewhere in this Agreement are not intended to be applicable to the indemnities provided to the Equityholders’ Representative under this section. The foregoing indemnities will survive the Closing, the resignation or removal of the Equityholders’ Representative or the termination of this Agreement.

(c) After the Closing, any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Equityholders’ Representative that is within the scope of the Equityholders’ Representative’s authority under Section 9.7(a) shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of all the Selling Securityholders and shall be final, binding and conclusive upon each such Selling Securityholder; and each Indemnified Person shall be entitled to rely exclusively upon any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction as being a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, each and every such Selling Securityholder. Purchaser, the Company and the Indemnified Persons are hereby relieved from any Liability to any Person for any acts done by them in accordance with such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of the Equityholders’ Representative.

9.8 Third-Party Claims. In the event that Purchaser becomes aware of a claim by a third party that would result in Indemnifiable Damages under Section 9.2 if it were assumed that such claim was ultimately determined in favor of such third party (a “Third-Party Claim”), Purchaser shall have the right in its sole discretion to conduct the defense of and to settle or resolve such Third-Party Claim. The Equityholders’ Representative shall have the right to receive copies of all pleadings, notices and communications with respect to such Third-Party Claim to the extent that receipt of such documents does not adversely affect any privilege relating to any Indemnified Person (and in such event, Purchaser shall cooperate in good faith with the Equityholders’ Representative to provide such information to the Equityholders’ Representative in a manner that does not adversely affect such applicable privilege, including by entering into joint defense agreements or similar arrangements). However, Purchaser shall have the right in its sole discretion to determine and conduct the defense of any Third-Party Claim and the settlement, adjustment or compromise of such Third-Party Claim. Unless otherwise consented to in writing in advance by Purchaser in its sole discretion, the Equityholders’ Representative and its Affiliates may not participate in any Third-Party Claim or any action related to such Third-Party Claim (including any discussions or negotiations in connection with the settlement, adjustment or compromise thereof). In the event that the Equityholders’ Representative has consented to the amount of any settlement or

resolution by Purchaser of any such claim (which consent shall not be unreasonably withheld, conditioned or delayed and which consent shall be deemed to have been given unless the Equityholders’ Representative shall have objected within 30 days after a written request therefor by Purchaser), or if the Equityholders’ Representative shall have been judicially determined to have unreasonably withheld, conditioned or delayed its consent to the amount of any such settlement or resolution, neither the Equityholders’ Representative nor any Selling Securityholder shall have any power or authority to object under this Article IX to the amount of any claim by or on behalf of any Indemnified Person against the Holdback Fund for indemnity with respect to such settlement or resolution. Notwithstanding anything to the contrary contained herein, the Equityholders’ Representative shall not be entitled to object to a claim for Indemnifiable Damages incurred by an Indemnified Person in connection with the defense, enforcement, settlement or resolution (including reasonable attorneys’ fees, other professionals’ and experts’ fees and court or arbitration costs) of a Third-Party Claim on the basis that there has been no ultimate determination (including a judgment of a court or a finding of an arbitral body) with respect to such Third-Party Claim. Notwithstanding the foregoing, to the extent that this Section 9.8 conflicts with the provisions of Section 6.12(e) with respect to Tax Claims, Section 6.12(e) will apply to the conduct of Tax Claims.

9.9 Treatment of Indemnification Payments. Purchaser, the Equityholders’ Representative and the Selling Securityholders agree to treat (and cause their respective Affiliates to treat) any payment received by the Indemnified Persons pursuant to this Article IX as adjustments to the Total Consideration payable or issuable for the Purchased Shares for all Tax purposes, to the maximum extent permitted by Applicable Law.

10.1 Survival of Representations, Warranties and Covenants.

If the Stock Purchase is consummated, all covenants, agreements and obligations of the parties hereto shall expire and be of no further force or effect as of the Closing, except to the extent such covenants, agreements and obligations provide that they are to be performed after the Closing; provided that no right to indemnification pursuant to Article IX in respect of any claim based upon any breach of a covenant, agreement or obligation shall be affected by the expiration of such covenant, agreement or obligation.
