August 18, 2009

Mr. Todd Spartz

158 Tillman Avenue

San Jose, CA 95126

Dear Todd:

On behalf of Selectica, Inc. (the “Company”), I am pleased to offer you employment on the following terms and conditions:

1. Position: Your initial title will be Chief Financial Officer and you will be employed as a regular, full-time employee reporting directly to the Office of the CEO. While you render services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company. By signing this letter agreement, you confirm to the Company that you have no contractual commitments or other legal obligations that would prohibit you from performing your duties for the Company.

2. Salary: The Company will pay you a starting salary at the rate of $220,000 per year, payable in accordance with the Company’s standard payroll schedule. This salary will be subject to adjustment pursuant to the Company’s employee compensation policies in effect from time to time. In addition, you will be eligible to be considered for an incentive bonus for each fiscal year of the Company. The bonus (if any) will be awarded based on objective or subjective criteria established by the Company’s Office of the CEO and approved by the Company’s Board of Directors. Your target bonus will be equal to 30% of your annual base salary. Any bonus for the fiscal year in which your employment begins will be prorated, based on the number of days you are employed by the Company during that fiscal year. Any bonus for a given fiscal year will be paid within 2 ¹/2 months after the close of that fiscal year, but only if you are still employed by the Company at the time of payment. The determinations of the Company’s Board of Directors with respect to your bonus will be final and binding. With respect to the current fiscal year (FY10), you can expect to be paid at least 50% of your bonus, but only if you are still employed by the Company at the time of payment.

3. Restricted Stock Units: You will receive 200,000 restricted stock units representing shares of the Company’s Common Stock (the “Units”). You will vest in 25% of the Units after completing 12 months of continuous service, and the remaining balance will vest in quarterly installments over the next 36 months of continuous service. The Units will be settled on the earliest Permissible Trading Day after they vest. In addition, 100% of the Units will vest and be settled immediately if the Company is subject to a Change in Control, as defined in Company’s 1999 Equity Incentive Plan (the “EIP”). The grant of the Units will be subject to the other terms and conditions set forth in the EIP and the Company’s form of Stock Unit Agreement. A

“Permissible Trading Day” is a day on which you are able to sell shares of the Company’s Common Stock in a public market without violating applicable laws or Company policies, as defined more specifically in your Stock Unit Agreement. Additionally, based upon certain Performance based criterion subject to the approval of the Company’s Board of Directors or its Compensation Committee, you will receive 200,000 restricted stock units representing shares of the Company’s Common Stock (the “Units”) subject to the identical terms (except for 4 year vesting) as described above.

4. Benefits: You will be entitled to receive employee benefits, including PTO and holidays, under the Company’s standard employee benefits program, as it may be amended from time to time. Your eligibility to receive employee benefits will be subject in each case to the generally applicable terms and conditions of the benefit plan in question and to the determinations of any person or committee administering such plan.

5. Severance Benefits:

General. If the Company terminates your employment for any reason other than Cause or Permanent Disability and a Separation occurs, then you will be entitled to the benefits described in this Section 5.¹ However, this Section 5 will not apply unless you (i) have returned all Company property in your possession, (ii) have resigned as a member of the Boards of Directors of the Company and all of its subsidiaries, to the extent applicable, and (iii) have executed a general release of all claims that you may have against the Company or persons affiliated with the Company. The release must be in the form prescribed by the Company, without alterations. You must execute and return the release on or before the date specified by the Company in the prescribed form (the “Release Deadline”). The Release Deadline will in no event be later than 60 days after your Separation. If you fail to return the release on or before the Release Deadline, or if you revoke the release, then you will not be entitled to the benefits described in this Section 5.

Salary Continuation. If the Company terminates your employment for any reason other than Cause or Permanent Disability and a Separation occurs, then the Company will continue to pay your base salary for a period of three (3) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures. The salary continuation payments will commence within 30 days after the Release Deadline and, once they commence, will be retroactive to the date of your Separation. This Agreement also provides for continuation of your base salary and health benefits for nine (9) months should your employment terminate for any reason within twelve (12) months after the Company is subject to a Change in Control.

COBRA. If the Company terminates your employment for any reason other than Cause or Permanent Disability, a Separation occurs, and you elect to continue your health insurance coverage under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) following your Separation, then the Company will pay the same portion of your monthly premium under COBRA as it pays for active employees until the earliest of (i) the close of the three-month period following your Separation, (ii) the expiration of your continuation coverage under COBRA or (iii) the date when you become eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment.

Accelerated Vesting. If the Company is subject to a Change in Control, then 100% of the Restricted Shares, regardless of the vesting schedule will become vested, provided you remain employed by the Company at the time of the Change in Control.

6. Tax Matters:

(a) Withholding. All forms of compensation referred to in this letter agreement are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law.

(b) Section 409A. For purposes of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), each salary continuation payment under Section 5(b) is hereby designated as a separate payment. If the Company determines that you are a “specified employee” under Section 409A(a)(2)(B)(i) of the Code at the time of your Separation, then (i) the salary continuation payments under Section 5(b), to the extent that they are subject to Section 409A of the Code, will commence during the seventh month after your Separation and (ii) the installments that otherwise would have been paid during the first six months after your Separation will be paid in a lump sum when the salary continuation payments commence.

(c) Tax Advice. You are encouraged to obtain your own tax advice regarding your compensation from the Company. You agree that the Company does not have a duty to design its compensation policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or its Board of Directors related to tax liabilities arising from your compensation.

7. Interpretation, Amendment and Enforcement: This letter agreement and Exhibit A constitute the complete agreement between you and the Company, contain all of the terms of your employment with the Company and supersede any prior agreements, representations or understandings (whether written, oral or implied) between you and the Company. This letter agreement may not be amended or modified, except by an express written agreement signed by both you and a duly authorized officer of the Company. The terms of this letter agreement and the resolution of any disputes as to the meaning, effect, performance or validity of this letter agreement or arising out of, related to, or in any way connected with, this letter agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”) will be governed by California law, excluding laws relating to conflicts or choice of law. You and the Company submit to the exclusive personal jurisdiction of the federal and state courts located in California in connection with any Dispute or any claim related to any Dispute.
