EMPLOYMENT AGREEMENT

EXHIBIT 10.29

EMPLOYMENT AGREEMENT

This Employment Agreement (the “Agreement”) is made and entered into effective as of October 5, 2005 (the “Effective Date”), by and between James F. Voelker (the “Employee”) and InfoSpace, Inc. (the “Company”). This Agreement serves as a renewal of the employment agreement entered into between Employee and the Company dated December 21, 2002 and replaces and supersedes any prior employment agreements that Employee may have entered into with the Company prior to the Effective Date.

In consideration of the mutual covenants herein contained, the continuing employment of the Employee by the Company, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows:

1. Duties and Scope of Employment. The Company shall employ Employee in the position of Chief Executive Officer. Employee will render such business and professional services in the performance of his duties, consistent with Employee’s position within the Company, as shall reasonably be assigned to him by the Company’s Board of Directors (the “Board”). Only the Board shall have the right to revise such responsibilities from time to time, as the Board deems necessary or appropriate. The Compensation Committee shall have the right to revise Employee’s compensation as provided for in Section 5 below, consistent with the provisions of this Agreement.

2. Obligations. While employed hereunder, Employee will perform his duties faithfully and to the best of his ability. Employee agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the prior approval of the Board; provided, however, that Employee may engage in non-competitive business or charitable activities so long as such activities do not materially interfere with Employee’s responsibilities to the Company. Outside board seats shall be subject to the prior approval of the Board.

3. Board Membership. While employed hereunder, Employee will serve as a member and Chairman of the Board, subject to any required Board and/or stockholder approval.

4. Employment Term. Employee’s employment with the Company pursuant to this Agreement shall commence on the Effective Date and shall continue, unless otherwise terminated earlier as provided in Section 6 hereof, until December 31, 2008 (the “Employment Term”); provided, however, that the Employment Term may be extended by mutual agreement of the Company and Employee on such terms as they may agree upon in writing. At least ninety (90) days prior to the end of the Employment Term, the Company shall notify the Employee as to whether or not the Company chooses to extend the Employment Term. If the Company chooses not to extend the Employment Term, following such notification by the Company and upon the Employment Term’s expiration, the Employee shall become an “at-will” employee of the Company. If the Employee terminates his employment while an at-will employee following the Employment Term’s expiration, and signs and does not revoke a Release, then, subject to Employee’s compliance with Section 9, the Employee shall be entitled to receive the following benefits:

(a) Continuing payments of severance pay (less applicable withholding taxes) at a rate equal to his base salary, as then in effect, for a period of six (6) months from the date of such termination, to be paid periodically in accordance with the Company’s normal payroll policies.

(b) The same level of health (i.e., medical, vision and dental) coverage and benefits as in effect for the Employee on the day immediately preceding the day of the Employee’s termination of employment; provided, however, that (a) the Employee constitutes a qualified beneficiary, as defined in Section 4980B(g)(1) of the Internal Revenue Code of 1986, as amended; and (b) Employee elects continuation coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), within the time period prescribed pursuant to COBRA. The Company shall continue to provide Employee with Company-paid health coverage until the earlier of (i) the date Employee is no longer eligible to receive continuation coverage pursuant to COBRA, or (ii) twelve (12) months from the termination date.

(c) One hundred percent (100%) of the Employee’s then unvested stock options shall immediately vest and become exercisable and Employee shall have twelve (12) months following the Termination Date to exercise such vested shares; provided, however, that in the event of a conflict between the terms and conditions of any such stock option agreement and this Agreement, the terms and conditions of this Agreement shall prevail unless the conflicting provision(s) in any such stock option agreement shall be more favorable to Employee in which case the provision(s) more favorable to Employee shall govern; provided further, however, that notwithstanding the foregoing in no event shall the extended twelve (12) month exercise period specified in this Section 4(c) modify or extend the Expiration Date of any stock option as set forth in such stock option agreement.

5. Compensation and Benefits.

(a) Base Compensation. The Company shall pay Employee as compensation for Employee’s services hereunder an annual base salary of $400,000. Such salary shall be subject to applicable tax withholding and shall be paid periodically in accordance with normal Company payroll practices. The base salary shall be subject to annual review by the Compensation Committee of the Board but in no event shall be less than $400,000.

(b) Incentive Bonus. In addition to the base salary, Employee may receive a performance bonus during each year of employment with the Company under this Agreement equal to an amount to be determined by the Compensation Committee of the Board. The amount of such annual performance bonus shall not be less than fifty percent (50%) of Employee’s then current base salary for the applicable fiscal year. Such performance bonus, if any, shall be based upon performance objectives to be mutually determined by the Compensation Committee of the Board and the Employee.

(c) Benefits. Employee shall be eligible to participate in the employee benefit plans which are available or which become available to other employees of the Company, with the adoption or maintenance of such plans to be in the discretion of the Company, subject in each case to the generally applicable terms and conditions of the plan or program in question and to the determination of any committee administering such plan or program. Such benefits shall include participation in the Company’s group medical, life, disability, and retirement plans, and any supplemental plans available to senior executives of the Company from time to time. Employee will also be entitled to paid vacation in accordance with the Company’s vacation policy for senior executives. The Company reserves the right to change or terminate its employee

2

benefit plans and programs at any time. Employee shall be entitled to business or first class air travel on any business travel outside of North America.

(d) Expenses. The Company will reimburse Employee for reasonable business expenses incurred by Employee in the furtherance of or in connection with the performance of Employee’s duties hereunder, in accordance with the Company’s expense reimbursement policy as in effect from time to time.

As of January 3, 2006, Employee will be granted a non-qualified stock option to purchase 450,000 shares of the Company’s common stock at an exercise price equal to the per share equivalent of the fair market value of the Company’s common stock on the date of grant as determined by the closing price of the Company’s common stock on NASDAQ NMS on the date of grant, or, if there is no such reported price on the date of grant, the closing price on the trading day on NASDAQ NMS first preceding the date of grant (the “Option”). Subject to the accelerated vesting provisions set forth herein, 1/36 of the shares subject to the Option shall vest monthly beginning one month after the Effective Date subject to Employee signing this Agreement prior to January 1, 2006 and subject to Employee’s continued full-time employment by the Company on the relevant vesting dates.

The Option will be subject to the terms and conditions of the Company’s Restated 1996 Flexible Stock Incentive Plan (the “Option Plan”) and the applicable stock option agreement by and between Employee and the Company (the “Option Agreement”), which documents are incorporated herein by reference; provided, however, that to the extent the Option Agreement is inconsistent with this Agreement, this Agreement shall control.

These payments shall be made promptly upon termination and within the period of time mandated by applicable law. Employee shall retain all options that are vested as of the Termination Date and such options may be exercised in accordance with the provisions of the Option Plan and the Option Agreement(s). All unvested options will be immediately forfeited as of the Termination Date.

(b) Termination by Company without Cause. The Company may terminate Employee’s employment without Cause upon thirty (30) days written notice to Employee.

(i) Receive continuing payments of severance pay (less applicable withholding taxes) at a rate equal to his base salary and 100% of his annual bonus rate, as then in effect, for a period of twelve (12) months from the date of such termination, to be paid periodically in accordance with the Company’s normal payroll policies.

Notwithstanding the provisions of this Section 6, during the first six (6) months after termination, Employee’s severance benefits will accrue and be paid in a lump sum payment in the seventh month after termination with Employee receiving monthly payments thereafter for the remaining severance benefits, unless the Company reasonably determines that under Internal Revenue Service guidance, the tax under Internal Revenue Code Section 409A does not apply to such payments.

(e) Termination by Employee for Good Reason. If Employee terminates employment with the Company for “Good Reason” (as defined herein) within ninety (90) days following a Good Reason event, and Employee signs and does not revoke a Release, then, subject

4

to Employee’s compliance with Section 9, Employee shall be entitled to the same benefits that he would receive in Section 6(b) above, unless such termination by the Employee occurs under the Change of Control circumstances described in Section 7, in which case Employee shall be entitled to the benefits described in such Section 7.

7. Change of Control Benefits. If Employee (i) is terminated other than for Cause by the Company within ninety (90) days prior to a “Change of Control” (as defined herein) or in connection with a Change of Control or (ii) is terminated other than for Cause by the Company (or its successor corporation) or resigns for Good Reason within eighteen (18) months following a Change of Control, and Employee signs and does not revoke a Release, then, subject to Employee’s compliance with Section 9, Employee shall be entitled to the following benefits:

(d) One hundred percent (100%) of the Employee’s then unvested stock options shall immediately vest and become exercisable and Employee shall have twelve (12) months following the Termination Date to exercise such vested shares; provided, however, that in the event of a conflict between the terms and conditions of any such stock option agreement and this Agreement, the terms and conditions of this Agreement shall prevail unless the conflicting provision(s) in any such stock option agreement shall be more favorable to Employee in which case the provision(s) more favorable to Employee shall govern; provided further, however, that notwithstanding the foregoing in no event shall the extended twelve (12) month exercise period specified in this Section 7(d) modify or extend the Expiration Date of any stock option as set forth in the applicable stock option agreement

If Employee remains employed by the Company or its successor for twelve (12) months following a Change in Control, and Employee, if applicable, signs and does not revoke a Release, then, subject to Employee’s compliance with Section 9, one hundred percent (100%) of Employee’s then unvested stock options shall immediately vest and become exercisable.

Notwithstanding the provisions of this Section 7, during the first six (6) months after termination, Employee’s severance benefits will accrue and be paid in a lump sum payment in the seventh month after termination with Employee receiving monthly payments thereafter for

5

the remaining severance benefits, unless the Company reasonably determines that under Internal Revenue Service guidance, the tax under Internal Revenue Code Section 409A does not apply to such payments.

Notwithstanding the foregoing, in the event that the benefits provided for in this Section 7 (i) constitute “parachute payments” within the meaning of Section 280G of the Code, and (ii) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then Employee’s benefits otherwise payable under this Section 7 shall be reduced by the minimum extent necessary such that no portion of such benefits would be subject to the Excise Tax. Unless the Company and Employee otherwise agree in writing, any determination required under this Section 7 shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon Employee and the Company for all purposes. For purposes of making the calculations required by this Section 7, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Section 280G and 4999 of the Code.
