In this Agreement, any reference to a Party's "knowledge," unless otherwise qualified, means the knowledge such Party would have after reasonable inquiry of the Party's managers and officers.

As used in this Agreement, the word "Subsidiary" means, with respect to any Party, any corporation or other organization, whether incorporated or unincorporated, of which at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the Board of Directors or others performing similar functions with respect to such corporation or other organization is directly or indirectly owned or controlled by such Party or by any one or more of its Subsidiaries, or by such Party and one or more of its Subsidiaries.

Except as disclosed in a disclosure schedule, which references the specific representations and warranties as to which the exception is made (the "Disclosure Schedule"), Seller and the Founders jointly and severally represent and warrant to Kintera and Purchaser as of the date of this Agreement as follows:

Section 3.1 Organization, Standing and Power. Seller is a limited liability company duly formed, validly existing and in good standing under the laws of the jurisdiction of its formation, has all requisite power to own, lease and operate its properties and to carry on its business as currently being conducted and as currently proposed to be conducted, and is duly qualified to transact business and is in good standing in each jurisdiction in which the nature of its operations requires such qualification, except where failure to be so qualified or in good standing would not have a Material Adverse Effect on the Seller or the Assets. Seller has delivered to Kintera or Purchaser true and correct copies of its charter documents (including its operating agreement, any documents required to be filed with the jurisdiction of its formation to complete such formation and any other governing documents), as amended to date. Seller is not in violation of any of the provisions of its charter documents. Except as set forth on the Disclosure Schedule, Seller does not directly or indirectly own any equity or similar interest in, or any interest convertible or exchangeable or exercisable for any equity or similar interest in, any corporation, joint venture or other business association or entity. Seller has no Subsidiaries.

Section 3.2 Authority; Required Filings and Consents.

(a) Seller and each Founder have all requisite power and authority to enter into this Agreement and the Transaction Documents (as defined below) and to consummate the transactions contemplated hereby and thereby. The execution and delivery of this Agreement and all ancillary agreements referenced herein and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all necessary action on the part of Seller, its managers (or persons serving in a governing capacity or capacity similar to a corporation's board of directors) (the "Managers") and its members (or other owners of equity interests in Seller) ("Members"). This Agreement, the Securityholders Agreement in substantially the form attached hereto as Exhibit A (the "Securityholders Agreement"), the Vesting Agreement in substantially the form attached hereto as Exhibit D (the "Vesting Agreement") the Option Agreements in substantially the form of Exhibit E (the "Option Agreements") and all ancillary agreements executed and delivered by Seller and the Founders as required by this Agreement (collectively, the "Transaction Documents") have been or will be duly executed and delivered by Seller and/or the Founders, as applicable, and constitute or will constitute the valid and binding obligations of Seller and/or the Founders, as applicable, enforceable against Seller and/or the Founders, as applicable, in accordance with their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, moratorium or other similar laws affecting or relating to creditors' rights generally, and general principles of equity. The Managers of Seller have unanimously (i) approved this Agreement and the sale of the Assets, (ii) determined that in its opinion the sale of the Assets is in the best interests of the Members of Seller and is on terms that are fair to such Members and (iii) recommended that the Members of Seller approve this Agreement.

(b) The execution and delivery by Seller and the Founders of this Agreement and the other Transaction Documents to which Seller and the Founder is or will be a party does not, and the consummation of the transactions contemplated hereby and thereby will not, (i) conflict with, or

result in any violation or breach of any provision of, the charter documents of Seller, (ii) result in any violation or breach of or constitute (with or without notice or lapse of time, or both) a default under, or give rise to a right of termination, cancellation or acceleration of any obligation or loss of any benefit under, any note, mortgage, indenture, lease, contract or other agreement or obligation to which Seller or any Founder is a party or by which Seller, any Founder, or any of the Assets may be bound except where such violation, breach or right would not have a Material Adverse Effect on the Seller or the Assets, or (iii) conflict with or violate any permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Seller, any Founder, or any of the Assets except where such conflict or violation would not have a Material Adverse Effect on the Seller or the Assets.

(c) No consent, approval, order or authorization of, or registration, declaration or filing with, any court, administrative agency or commission or other governmental authority or instrumentality ("Governmental Entity") is required by or with respect to Seller or the Assets in connection with the execution and delivery of the Transaction Documents or the consummation of the transactions contemplated hereby, and thereby, except for (i) filings, if any, required under Regulation D of the Securities Act of 1933; (ii) such consents, approvals, orders, authorizations, registrations, declarations and filings as may be required under applicable state securities laws; and (iii) such other consents, authorizations, filings, approvals and registrations which, if not obtained or made, would not prevent or materially alter or delay any of the transactions contemplated by this Agreement.

Section 3.3 Capitalization. The authorized equity interests of Seller consist of membership interests ("Membership Interests"), all of which are issued and outstanding to the Founders in the percentages set forth on Schedule 3.3. All outstanding Membership Interests are duly authorized, validly issued, fully paid and non-assessable and are free of any liens or encumbrances, and are not subject to preemptive rights or rights of first refusal (in each case that have not been complied with or waived), the organizational documents of Seller or any agreement to which Seller is a party or by which it is bound. Other than the Membership Interests, Seller has no other equity interests. Except as disclosed in Schedule 3.3 of the Disclosure Schedule, there are no options, warrants, calls, rights, commitments or agreements of any character to which Seller is a party or by which it is bound obligating Seller to issue, deliver, sell, repurchase or redeem or cause to be issued, delivered, sold, repurchased or redeemed, any Membership Interests or any other class of equity or debt security of Seller or obligating Seller to grant, extend, accelerate the vesting of, change the price of, or otherwise amend or enter into any such option, warrant, call, right, commitment or agreement. Except as set forth in Schedule 3.3 of the Disclosure Schedule, there are no contracts, commitments or agreements relating to voting, purchase or sale of the Membership Interests between Seller and any of its Members.

All of the prices charged by Seller in connection with the marketing or sale of any of its services have been in compliance with all applicable laws and regulations, except for such noncompliance that would not have a Material Adverse Effect on Seller or the Assets. No claims have been asserted or, to the knowledge of Seller, threatened against Seller with respect to unfair competition, false advertising, or any other

violation of any laws or regulations relating to anti-competitive practices or unfair trade practices of any kind, and, to the knowledge of Seller, no specific situation, set of facts, or occurrence provides any basis for any such claim, except for such claims that would not have a Material Adverse Effect on Seller or the Assets.

Section 3.14 Environmental Matters.

(a) None of the properties or facilities of Seller is in violation of any federal state or local law, ordinance, regulation or order relating to the protection of public health and safety, the protection of worker health and safety or the environmental conditions on, under or about the properties or facilities, including, but not limited to, soil and ground water condition except where the violations would not constitute a Material Adverse Effect.

Section 3.15 Employee Benefit Plans.

(a) Schedule 3.15 of the Disclosure Schedule lists, with respect to Seller, any subsidiary of Seller and any trade or business (whether or not incorporated) which is treated as a single employer with Seller (an "ERISA Affiliate") within the meaning of Section 414(b), (c), (m) or (o) of the Code, each plan, program, policy, practice, contract, agreement or other arrangement providing for employment, compensation, severance, relocation, termination pay, deferred compensation, sabbatical, performance awards, bonus, stock or stock-related awards, fringe benefit, cafeteria benefit, dependent care, including without limitation, each "employee benefit plan" as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA") which is or has been maintained, contributed to, or required to be contributed by Seller or any ERISA Affiliate or with respect to which Seller or any ERISA Affiliate has or may have any liability or obligation (collectively, the "Seller Employee Plans"). None of the Seller Employee Plans promises or provides retiree medical or other retiree welfare benefits to any person. Seller does not have any plan or commitment to establish any new Seller Employee Plans or amend any Seller Employee Plan which would materially increase the expense of maintaining such Plan above the level of expense incurred with respect to that Plan for the most recent fiscal year included in Seller's financial statements.

(b) Documents. Seller has furnished to Kintera true and complete copies of documents relating to each Seller Employee Plan, including (without limitation) plan documents, trust documents, the most recent determination or opinion letter, group annuity contracts, plan amendments, insurance policies or contracts, individual participant agreements, employee booklets, administrative service agreements, summary plan descriptions, compliance and nondiscrimination tests for the last three plan years, Form 5500 reports filed for the last three plan years, standard Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA") forms and notices, all registration statements and prospectuses, and any material employee communications relating to any Seller Employee Plan.

under or violation of and have no knowledge of any default or violation by any other party to, any of the Seller Employee Plans except as would not have a Material Adverse Effect on Seller. Any Seller Employee Plan intended to be qualified under Section 401(a) of the Code has obtained from the Internal Revenue Service a favorable determination letter or opinion letter as to its qualified status under the Code and nothing has occurred since the issuance of each such letter which could reasonably be expected to cause the loss of the tax-qualified status of any Seller Employee Plan subject to Code Section 401(a). Seller and each of its subsidiaries have complied in all material respects with, and have no material unsatisfied obligations to any individual under, the health care continuation and notice provisions of COBRA, or any applicable state continuation coverage requirements, the Family and Medical Leave Act of 1993, the Health Insurance Portability and Accountability Act and the Cancer Rights Act of 1998. There are no suits, administrative proceedings, actions or other litigation which have been brought, or to the knowledge of Seller threatened, against or with respect to any such Seller Employee Plan, including specifically any audit or inquiry by the Internal Revenue Service or the Department of Labor. All contributions required to be made by Seller, any subsidiary or ERISA Affiliate, to any Seller Employee Plan have been made timely in accordance with applicable ERISA requirements and have either been made on or before their due dates or a reasonable amount has been paid or accrued, in accordance with Seller's ordinary business procedures for the current plan years.

(d) No Title IV or Multiemployer Plan. Seller does not now, nor has it ever, maintained, established, sponsored, participated in, or contributed to, any pension plan which is subject to Title IV of ERISA or Section 412 of the Code. Neither Seller nor any ERISA Affiliate is a party to, has made or is required to make any contribution to, or otherwise incurred any obligation or liability (including contingent liability) under, any "multiemployer plan" as defined in Section 3(37) of ERISA. Neither Seller nor any ERISA Affiliate has any actual or potential withdrawal liability (including contingent liability) for any complete or partial withdrawal from any multi-employer plan.

(e) Effect of Transaction. The consummation of the transactions contemplated by this Agreement will not (i) entitle any current or former employee or other service provider of Seller, to severance benefits or any other payment (including, without limitation, unemployment compensation, golden parachute or bonus), except as expressly provided in this Agreement or (ii) accelerate the time of payment or vesting of any such benefits, or increase the amount of compensation due any such employee or service provider. No benefit payable or which may become payable by Seller pursuant to any Seller Employee Plan or as a result of or arising under this Agreement shall constitute an "excess parachute payment" (as defined in Section 280G(b)(1) of the Code) which is subject to the imposition of an excise Tax under Section 4999 of the Code or the deduction for which would be disallowed by reason of Section 280G of the Code. Each Seller Employee Plan can be amended, terminated or otherwise discontinued after the Effective Time in accordance with its terms without material liability to Kintera.

Section 3.16 Compliance with Laws. Seller has complied with, is not in violation of, and has not received any notices of violation with respect to, any statute, law or regulation applicable to Seller, the ownership or operation of the Business, the Assets or the Founders except as such violation would not have a Material Adverse Effect on the Seller or the Assets.

Schedule 3.17 of the Disclosure Schedule contains a list of the names of all employees, independent contractors, consultants and advisors of Seller as of the date of this Agreement and their salaries or wages, other compensation (including any distributions to such employees, independent contractors, consultants and advisors of Seller in their capacity as members of Seller), dates of employment and positions and the date of the last increase in their compensation.

Section 3.18 Litigation. There is no action, suit, proceeding, claim, arbitration or known investigation pending before any agency, court or tribunal or, to the knowledge of Seller or the Founders, threatened against Seller, or Seller's properties or officers or Managers (in their capacities as such), the Founders or the Assets, or in which any of Seller, Seller's officers or Managers (in their capacities as such) or the Founders is a plaintiff. There is no judgment, decree or order against Seller, the Founders or, to the knowledge of Seller and the Founders, any of the Managers or officers (in their capacities as such).

Section 3.19 Restrictions on Business Activities. There is no agreement, judgment, injunction, order or decree binding upon Seller or the Founders which has or could reasonably be expected to have the effect of prohibiting or materially impairing any current business practice of Seller or the Founders or the operation of the Business as currently conducted.

Section 3.20 Governmental Authorization. Seller has obtained each governmental consent, license, permit, grant or other authorization of a Governmental Entity that is required for the operation of the Business (collectively, the "Seller Authorizations"), and all of such Seller Authorizations are in full force and effect except where failure to obtain such Seller Authorization would not have a Material Adverse Effect on the Seller or the Assets.

Section 3.21 Insurance. Schedule 3.21 of the Disclosure Schedule contains a list and description of all insurance policies in effect which are maintained by Seller or as to which Seller is an insured party. There is no claim pending under any of such policies as to which coverage has been questioned, denied or disputed by the underwriters of such policies.

The Seller's records, including the Seller's minute book, are complete and accurate in all material respects, and the signatures of all officers and Members and other persons appearing on all documents contained therein are the true signatures of the persons purporting to have signed the same. All actions reflected in such books and records were duly and validly taken in compliance with the laws of the applicable jurisdiction, except where non-compliance would not have a Material Adverse Effect, individually or in the aggregate, on Seller or the Assets.

Section 3.25 Accounts Receivable. The accounts receivable of Seller arising from the Business as set forth on the Seller Financial Statements or arising since the date thereof are valid and genuine, have arisen solely out of bona fide sales and deliveries of goods, performance of services and other business transactions in the ordinary course of business consistent with past practice, are not subject to

valid defenses, set-offs or counterclaims, and are fully collectible in the normal and ordinary course of business after billing at the full recorded amount thereof less, in the case of accounts receivable appearing on the Seller Financial Statements, the recorded allowance for collection losses on the Seller Financial Statements. Seller has no knowledge of any facts or circumstances generally (other than general economic conditions) which would result in any increase in the uncollectibility of such accounts receivable. The allowance for collection losses on the Seller Financial Statements has been determined in accordance with GAAP consistent with past practice. The accounts payable, accounts receivable and accrued expenses of Seller as of the day prior to Closing are set forth in Schedule 3.25.

Section 3.26 No Misrepresentation. No representation or warranty by Seller or the Founders in this Agreement, or any written statement, document, certificate or schedule furnished or to be furnished by or on behalf of Seller or Founders pursuant to this Agreement or in connection with the transactions contemplated hereby, when taken together, contains or shall contain any untrue statement of a material fact or omits or shall omit to state a material fact required to be stated therein or necessary in order to make such statements, in light of the circumstances under which they were made, not misleading. Seller has delivered to Kintera or Purchaser or its representatives true and complete copies of all documents which are referred to in this Article III or in the Disclosure Schedule.

Section 3.27 Use of Third Party Information. Seller complies with all applicable United States, and to the best of its knowledge, foreign privacy laws and regulations regarding the collection, retention, use and disclosure of personal information, and Seller takes all appropriate and industry standard measures to protect and maintain the confidential nature of the personal information provided to Seller by individuals. Seller has adequate technological and procedural measures in place to protect personal information collected from individuals against loss, theft and unauthorized access or disclosure. Seller does not knowingly collect information from or target children under the age of thirteen. Seller does not sell, rent or otherwise make available to third parties any personal information submitted by individuals. Seller has the full power and authority to use and to transfer all rights Seller has in any third party's personal information in Seller's possession and/or control to Kintera and Purchaser. Seller is not a party to any contract, nor is it subject to any other obligation that, following the Closing, would prevent Kintera and Purchaser and/or the affiliates of Kintera from using such information in a manner consistent with applicable privacy laws, customer privacy policies and industry standards regarding the disclosure and use of information.

Section 3.28 Investment Representations.

(a) Seller is obtaining the Shares solely for its own account and for investment and not with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act of 1933, as amended (the "Securities Act"). Seller further represents that it does not have any present intention of selling, offering to sell or otherwise disposing of or distributing its Shares or any portion thereof, other than as contemplated by Section 6.1; and that the entire legal and beneficial interest of the Shares it is receiving will be held for the account of, itself only and neither in whole nor in part for any other person.

(b) Knowledge of Kintera's Business. Seller is aware of Kintera's business affairs and financial condition and has acquired sufficient information about Kintera to reach an informed and knowledgeable decision to acquire the Shares. Seller further represents and warrants that it has discussed, or has had the opportunity to discuss, Kintera and its plans, operations and financial condition with its officers, has received all such information as it deems necessary and appropriate to enable it to evaluate the financial risk inherent in making an investment in the Shares and has received satisfactory and complete information concerning the business and financial condition of Kintera in response to all inquiries in respect thereof.

(c) Speculative Investment. Seller realizes that its purchase of the Shares will be a highly speculative investment, and it is able, without impairing its financial condition, to hold the Shares for an indefinite period of time and to suffer a complete loss on its investment.

(d) No Obligation to Register. Kintera has disclosed to Seller that:

(i) The sale of the Shares has not been registered under the Securities Act, and the Shares must be held indefinitely unless a transfer of it is subsequently registered under the Securities Act or an exemption from such registration is available, and that Kintera is under no obligation to register the Shares;

(ii) Kintera will make a notation in its records of the aforementioned restrictions on transfer and legends.

(e) Rule 144. Seller is aware of the provisions of Rule 144, promulgated under the Securities Act, which, in substance, permits limited public resale of "restricted securities" acquired, directly or indirectly, from the issuer thereof (or an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions, including among other things: the resale occurring not less than one year from the date Seller receives its Shares; the availability of certain public information concerning Kintera; the sale being through a broker in an unsolicited "broker's transaction" or in a transaction directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and that any sale of the Shares may be made by it only in limited amounts during any three-month period not exceeding specified limitations. Seller further represents that it understands that at the time it wishes to sell the Shares there may be no public market upon which to make such a sale, and that, even if such a public market then exists, Kintera may not be satisfying the current public information requirements of Rule 144, and that, in such event, it would be precluded from selling the Shares under Rule 144 even if the one-year minimum holding period had been satisfied. Seller represents that it understands that in the event all of the requirements of Rule 144 are not satisfied, registration under the Securities Act or compliance with an exemption from registration will be required; and that, notwithstanding the fact that Rule 144 is not exclusive, the staff of the Securities Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.

(f) Acknowledgement of Legends. Seller acknowledges that the certificate representing the Shares will bear the legends set forth in the Securityholders Agreement.

Section 3.29 Employee Matters. Seller is in compliance with all currently applicable laws and regulations respecting terms and conditions of employment including, without limitation, applicant and employee background checking, immigration laws, discrimination laws, verification of employment eligibility, employee leave laws, classification of workers as employees and independent contractors, wage and hour laws, and occupational safety and health laws, except where any failure to comply would not constitute a Material Adverse Effect. There are no proceedings pending or, to Seller's or the Founders' knowledge, reasonably expected or threatened, between Seller, on the one hand, and any or all of its current or former employees, on the other hand, including, but not limited to, any claims for actual or alleged harassment or discrimination based on race, national origin, age, sex, sexual orientation, religion, disability, or similar tortious conduct, breach of contract, wrongful termination, defamation, intentional or negligent infliction of emotional distress, interference with contract or interference with actual or prospective economic disadvantage. There are no claims pending, or, to Seller's or the Founders' knowledge, reasonably expected or threatened, against Seller under any workers' compensation or long term disability plan or policy. Seller has no unsatisfied obligations that would have a Material Adverse Effect on Seller to any employees, former employees, or qualified

beneficiaries pursuant to COBRA, HIPAA, or any state law governing health care coverage extension or continuation. Seller is not a party to any collective bargaining agreement or other labor union contract, nor does Seller know of any activities or proceedings of any labor union to organize its employees. Seller has provided all employees with all wages, benefits, relocation benefits, stock options, bonuses and incentives, and all other compensation which became due and payable through the date of this Agreement.

If the Closing occurs, all of the representations and warranties contained in Articles III and IV of this Agreement shall survive until *** from the Closing Date, at which time liability therefor shall cease, except as provided in the last sentence of this Section 8.1. Notwithstanding the foregoing, the representations and warranties contained in Sections *** shall survive indefinitely and the representations and warranties in Section *** shall survive until the lapsing of the appropriate statute of limitations, at which time liability therefor shall cease. The termination of any representation and warranty shall not affect any claim for breaches of representations or warranties (and the breaching Party shall continue to be liable therefor) if written notice thereof is given to the breaching Party or Parties on or prior to such termination date.

Section 8.2 Indemnification. Subject to the terms and conditions contained herein, holders of Shares (the "Indemnifying Parties") shall jointly and severally indemnify, defend and hold harmless Purchaser and Kintera, their officers, directors, employees and attorneys, all Subsidiaries and affiliates of Purchaser, and the respective officers, directors, employees and attorneys of such entities (all such persons and entities being collectively referred to as the "Purchaser Group") from, against, for and in respect of those losses, damages, costs and expenses (including reasonable legal fees and expenses) that any member of the Purchaser Group may sustain or incur to the extent caused by or arising out of (i) any breach of any of the representations, warranties or covenants made by Seller or the Founders in this Agreement or (ii) any claims described in Schedule 3.18 of the Disclosure Schedule (together with any Adjustment Amount, "Losses"), and that are subject to reimbursement as provided in this Section 8.2 ("Reimbursable Losses").

Subject to compliance with this Section 8, the indemnification obligations of the Indemnifying Parties may be satisfied *** Kintera *** Escrow Securities *** Stated Price *** Escrow Securities *** Reimbursable Losses (*** Escrow Securities ***). ***, Kintera *** Reimbursable Losses *** Kintera *** Purchaser *** Reimbursable Losses *** Reimbursable Losses. ***. "Stated Price" shall mean *** per share (subject to adjustment to reflect stock splits, combinations and other similar events affecting the shares of Kintera common stock). The obligations of the Indemnifying Parties in this Section 8 represent the Indemnifying Parties' *** and the Purchaser Group's *** for any breach of any of the representations, warranties or covenants made by Seller or the Founders in this Agreement, as well as any Adjustment Amount.

Section 8.3 Escrow Fund.

(a) At the Closing, the Escrow Securities shall be issued in the name of the Seller and be deposited with the Escrow Agent. *** shall constitute the "Escrow Fund" and shall be governed by the terms set forth herein and in the Securityholders Agreement. The Escrow Fund shall be available to compensate Purchaser or Kintera pursuant to the indemnification obligations of the Indemnifying Parties pursuant to Section 8.2. In the event Kintera issues any Additional Escrow Shares (as defined below) or declares a stock split, such shares will be issued in the name of the Seller and held by the Escrow Agent for the benefit of Seller and delivered to the Escrow Agent in the same manner as the Escrow Securities delivered at the Closing.

(b) Except for dividends paid in stock declared with respect to the Escrow Securities ("Additional Escrow Shares"), which shall be treated as Escrow Securities, any cash dividends paid with respect to the Shares will be delivered to Seller. Seller will have voting rights for the Escrow Securities deposited in the Escrow Fund so long as such Escrow Securities are held in Escrow.

Section 8.4 Indemnification Period. The indemnification period shall terminate *** from the Closing Date (the "Termination Date"); provided, however, that if any of the Escrow Securities subject to cancellation as set forth in this Section 8 are necessary to satisfy any unsatisfied claims specified in any Officer's Certificate delivered to Xxxxx Xxxxxx Xxxxxx, Jr. as agent for the Seller and the Founders (the "Securityholders' Agent") prior to the Termination Date with respect to facts and circumstances existing prior to the Termination Date, such Escrow Securities shall remain subject to this Section 8 until the resolution of such claims.

Section 8.5 Claims for Indemnification. If Kintera or the Purchaser becomes aware of any Losses for which Kintera or the Purchaser will seek indemnification, Kintera or the Purchaser shall deliver to the Escrow Agent, with a copy to the Securityholders' Agent, on or before the Termination Date, a certificate signed by any officer of Kintera or the Purchaser (an "Officer's Certificate") stating that with respect to the indemnification obligations set forth in Section 8.2, Losses exist and specifying in reasonable detail the individual items of such Losses included in the amount so stated, the date each such item was paid, or properly accrued or arose, the nature of the misrepresentation, breach of warranty, covenant or claim to which such item is related and an estimate of attorney's fees and expenses necessary to conclude the matter. If the Securityholders' Agent does not object to such claims within thirty (30) calendar days of the delivery of the Officer's Certificate to the Securityholders' Agent, after delivery of a written notice of cancellation (the "Cancellation Notice") to the Securityholders' Agent Kintera shall be entitled to receive from the Escrow Agent shares of Escrow Securities on a pro rata basis as among all holders of Shares, with all such Shares to be received from Escrow having an aggregate Stated Price equal to the Reimbursable Losses, and in such event the Escrow Agent shall deliver to Kintera the foregoing number of Escrow Securities. Kintera shall notify each of the Indemnifying Parties of the number of Shares that are subject to cancellation.

Section 8.6 Challenge of Third Party Claims. The Securityholders' Agent may elect to participate with Kintera to challenge any claims that are asserted by a third party for which Kintera has delivered an Officer's Certificate to the Escrow Agent (with a copy to the Securityholders' Agent). The Indemnifying Parties shall be liable for all costs incurred by the Securityholders' Agent in connection with any such challenge. In addition, the Indemnifying Parties must use counsel reasonably acceptable to Kintera. If the Securityholders' Agent elects to participate, the Securityholders' Agent must deliver a notice to Kintera within twenty (20) calendar days of the receipt of the Officers' Certificate. The Securityholders' Agent shall not, without Kintera's written consent, settle or compromise any third party claims or consent to entry of any judgment. Kintera shall consult with the Securityholders' Agent with respect to any claims asserted by a third party, and will inform the Securityholders' Agent of all material developments with respect to such claims, but Kintera shall have the right in its sole discretion to settle any claim.

Section 8.7 Objections to Claims. The Securityholders' Agent may object to the claim on the Officer's Certificate by delivery to Kintera (with a copy to the Escrow Agent) of such objection in writing within thirty (30) calendar days of the delivery of the Officer's Certificate to the Securityholders' Agent. In case the Securityholders' Agent shall so object in writing to any claim or claims by Kintera or Purchaser made in any Officer's Certificate, Kintera or Purchaser shall have thirty (30) days to respond in a written statement to the objection of the Securityholders' Agent. If after such thirty (30) calendar day period there remains a dispute as to any claims, the Securityholders' Agent and Kintera or Purchaser shall attempt in good faith for sixty (60) days to agree upon the rights of the respective parties with respect to each of such claims. If the Securityholders' Agent and Kintera or Purchaser should so agree, a memorandum setting forth such agreement shall be prepared and signed by both and the distribution or cancellation, if any, of Escrow Securities shall be made in connection therewith in accordance with Section 8.2 and 8.5.

Section 8.8 Resolution of Conflicts and Arbitration. If no agreement can be reached after negotiation between the parties pursuant to Section 8.7, either Kintera or the Purchaser or the Securityholders' Agent may, by written notice to the other, demand binding arbitration of the matter unless the amount of the Losses is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until a judgment has been entered or both parties agree to arbitration. Any conflicts arbitrated pursuant to this Section 8.8 shall be arbitrated in accordance with the provisions of Section 10.1 of this Agreement. In the event that a claim is resolved adversely to the Indemnifying Parties by arbitration pursuant to this Section 8.8, Kintera shall deliver to the Escrow Agent a copy of the award and the distribution or cancellation, if any, of Escrow Securities shall be made in connection therewith in accordance with Section 8.2 and 8.5.

Section 8.9 Maximum Payments. The maximum aggregate Losses recoverable by Kintera or the Purchaser from any Indemnifying Party under this Article VIII shall not exceed the number of Escrow Securities allocable to such Indemnifying Party hereunder, except in the case of any claim for indemnification under the provisions of this Article VIII which arises out of or results from *** of Seller or the Founders for which Kintera or the Purchaser shall be entitled to recover the number of Escrow Securities allocable to such Indemnifying Party hereunder plus its reasonable legal fees and expenses

Section 10.6 Entire Agreement. This Agreement (including the schedules and exhibits hereto and the other documents delivered pursuant hereto) and the other Transaction Documents constitute the entire agreement among the Parties concerning the subject matter hereof and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof, other than the Mutual Nondisclosure Agreement previously executed by Kintera and Seller.
