1. Duties and Scope of Employment.

(a) Position. The Company agrees to employ Executive in the position of Corporate Vice President, reporting to the Chief Executive Officer of the Company (the CEO).

(b) Obligations to the Company. Executive shall be permitted to serve as a member of the board of directors of the companies listed
on Exhibit BD attached hereto, which list may be supplemented with additional board memberships at the Executives request and the prior written consent of the Companys Board of Directors (the Board of Directors). Nothing
herein shall prohibit Executive from rendering commercial, charitable or professional services of any nature to any person or organization, whether or not for compensation provided such work does not adversely affect Executives obligations to
the Company hereunder. Executives employment will also be subject to the terms of the Employee Invention Assignment, Confidentiality and Arbitration Agreement executed by Executive concurrently with the execution of this Agreement.

(c) No Conflicting Obligations. During the time that this Agreement is in effect, Executive represents and warrants to the
Company that he is under no obligations or commitments, whether contractual or otherwise, that are inconsistent with his obligations under this Agreement. Executive represents and warrants that he will not use or disclose, in connection with his
employment by the Company, any trade secrets or other proprietary information or intellectual property in which Executive or any other person has any right, title or interest and that his employment by the Company as contemplated by this Agreement
will not infringe or violate the rights of any other person or entity.

(d) Effective Date. Executive shall commence
Employment under the terms of this Agreement upon the closing of the purchase transaction contemplated by that certain Membership Interest Purchase Agreement dated May 5, 2007 (the Purchase Agreement) between the Company, Executive
and the other parties thereto (the Effective Date).

annualized base salary of $225,000) and shall be payable in accordance with the Companys standard payroll schedule, currently bi-monthly. The compensation specified in this Section 2(a), together with any increases in such compensation

(b) 2007 Bonus. For the period from the Effective Date through
December 31, 2007, Executive shall have the opportunity to earn a performance bonus of $60,000.00 (the Annual Bonus). As a direct report to the Chief Executive Officer, Executive will participate in the K2 Executive bonus plan.
Based on such plan, Executive will receive payment of approved bonuses on both a quarterly and annualized basis, subject to approval by the Companys Compensation Committee. Except as otherwise provided in this Agreement, Executives
receipt of the Annual Bonus shall be contingent upon Executives continued employment through the end of the bonus period with respect to which it is payable; provided, Executive shall have the right to any pro rata portion of the Annual Bonus
in the event his employment is terminated by the Company Without Cause prior to the end of such bonus period. After 2007, the Annual Bonus shall be determined in good faith by the Company as soon as practicable after the end of the preceding bonus
period.

(c) Special Incentive Bonus. Executive shall be eligible to participate in the Special Incentive Bonus
program attached hereto as Exhibit A.

3. Executive Benefits. During the term of his employment, Executive shall be eligible to
participate in the employee benefit plans maintained by the Company for similarly situated employees, subject in each case to the generally applicable terms and conditions of the plan in question and to the determinations of any person or committee
administering such plan.

4. Paid Time Off. Direct reports to Companys Chief Executive Officer do not accrue and/or earn
personal time off (PTO). It is assumed that the executive knows when he/she should take time off. Given this policy, both Company and Executive confirm and agree that Executive may, at Executives election, take up to 3 weeks of
time off per year. Commencing on January 1, 2008 and for the remainder of the Term, Executive may, at Executives election, take up to 4 weeks time off per year in accordance with this Company policy, as it may be amended from time to
time.

5. Equity.

(a) Grant of Stock Options. Company will recommend that Executive be granted a stock option to purchase 100,000 shares of common stock of Kana. This grant recommendation is subject to approval by the Compensation
Committee after your employment begins. The option would vest over four years subject to a six-month cliff and will have an exercise price per share equal to the closing price of Kana common stock on the date of grant.

(b) Process. New hire stock grants are processed during the second full week of each month for those employees that commence
employment during the prior four weeks. For example, should Executive commence employment on May 2, 2007, the recommendation above would be processed during the week of May 14, 2007.

(c) Exercise of Options. The stock options granted pursuant to Section 5(a) above shall be subject to the Companys standard
form of stock option agreements, copies of which shall be executed by Executive as a condition of the grant and exercise.

applicable federal, state and local income taxes and the Excise Tax, results in the receipt by Executive on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under
Section 4999 of the Code. In the event Executives accelerated vesting, severance and other benefits is delivered in the manner described in (y) of this Paragraph 9(a), Executive agrees that such delivery is in full an final
satisfaction of the Termination Benefits set forth in Section 8 above.

determination, shall be made by the nationally recognized certified public accounting firm used by the Company immediately prior to the Change of Control Event or, if such firm declines to serve, such other nationally recognized certified public
accounting firm as may be designated by Executive (the Accountants). Such determination shall be made as soon as practicable following the Change of Control Event. The Accountants shall provide detailed supporting calculations both to
the Company and Executive at such time as is requested by the Company. For purpose of making the calculations required by this Section 9, the

Section 9. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations by this Section 9.
