TRANSITION AGREEMENT

This Transition Agreement made as of this 18th day of January 2010 between Unica Corporation (“Unica” or “Company”) and Richard Welch (“Mr. Welch”).

WHEREAS, Mr. Welch has been employed by the Company since May 2007, and has served as the Company’s Senior Vice President of Global Services since that time;

WHEREAS, the Company and Mr. Welch mutually desire to terminate Mr. Welch’s employment with the Company and Mr. Welch has indicated to the Company his desire to explore various professional opportunities which have been or may be presented to him; and

WHEREAS, the Company desires to secure his continued service for a minimum designated period of time to allow for the timely completion of his current assignments and to allow for an appropriate transition of his duties.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants contained herein, the parties agree as follows.

1. Contractual Status. The parties agree that Mr. Welch will remain employed as the Company’s Senior Vice President of Global Services from the date of this Transition Agreement until his resignation as Senior Vice President of Global Services on January 31, 2010 (the “Termination Date”). The parties further agree that Mr. Welch will continue to perform those duties and responsibilities customary and consistent with his position as Senior Vice President of Global Services until the Termination Date. Up to and including the Termination Date, Mr. Welch will continue to receive the same base salary, and fringe benefits to which he was entitled immediately prior to the execution date of this Transition Agreement. On the Termination Date, Mr. Welch will be paid all wages earned but unpaid and all accrued but unused vacation time up to and through the Termination Date.

2. Consideration.

(a) Release. Upon the cessation of Mr. Welch’s employment pursuant to Section 1 above, Mr. Welch shall execute the Release of Claims attached hereto as Exhibit A and, conditioned on the execution and nonrevocation by Mr. Welch of the Release of Claims, Mr. Welch or, in the event of Mr. Welch’s death, his estate, shall be entitled to the compensation and benefits set forth in subparagraphs 2(b)-(h) below.

(b) Continued Salary. In consideration for the promises made herein, the Company shall provide Mr. Welch bi-weekly payments commencing on the next regularly scheduled pay cycle following the date the Release of Claims referenced in paragraph 2 above becomes binding upon him in the amount of $9,200.00, less applicable taxes and withholdings, for a period of two (2) months. The total gross amount of these payments is $36,800.

(c) Executive Support Services. The Company will pay up to an aggregate amount of $5,000 for any third-party executive services fees (including fees for professional development or educational courses) incurred by Mr. Welch, provided that such services take place prior to September 30, 2010. Mr. Welch shall instruct any such third party to invoice the Company directly for such fees. Alternatively, Mr. Welch may submit receipts for such third party expenses via Unica Expense Report, to be approved by the Unica SVP of HR, and re-embursed by check.

(e) Computer. The Company will allow Mr. Welch to keep the laptop computer (and related peripherals) previously provided by the Company. However, this transfer of ownership is contingent upon Mr. Welch’s cooperation in allowing the Company to remove all Company programs, applications and information from the computer prior to his termination of employment. The Company transfers ownership of the computer (and related peripherals) in “as is” condition and makes no promises nor provides any warranties regarding the condition of the computer.

(f) Amended Equity Grants. The Company agrees to amend Mr. Welch’s outstanding equity awards to provide for continued vesting beyond the Termination Date through and including June 30, 2010 (the “End Vest Date”) as follows:

All vesting in Company equity (e.g. restricted stock units or options) will cease on the End Vest Date, and the period in which Mr. Welch may exercise any vested non-qualified stock options shall be extended to be the period ending 90 days after the End Vest Date.

Except as set forth above, all terms and conditions of any outstanding equity award to Mr. Welch shall remain unchanged and be governed by the 2005 Stock Incentive Plan, as amended (the “Plan”), and any other equity grant agreement with the Company (“Equity Agreements”). In addition, any amounts contributed by Mr. Welch under the Company’s Employee Stock Purchase Plan for the current offering period shall be refunded to Mr. Welch and included in the payment made to Mr. Welch on the Termination Date.

(g) Health and Dental Insurance. The Termination Date will serve as the “qualifying event” under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”). If Mr. Welch timely elects to continue medical and/or dental insurance coverage after the Termination Date in accordance with the provisions of COBRA, the Company will pay the Company portion of his monthly premium payments through June 30, 2010. Mr. Welch still will be responsible for the employee portion of the premium during the Payment Period (such amounts will be deducted from the salary continuation payments) and shall remit employee portion of the premium from April 1, 2010 until June 30, 2010 to the Company.

(h) Taxes. All amounts set forth in this Section 2 are subject to any applicable federal, state and local deductions, withholdings, payroll and other taxes.

(j) Termination of Benefits. With the exception of the benefits set forth in this Section 2, all other benefits under any Company provided benefit plan, program, contract or practice will end upon the Termination Date, except as provided by law.

(k) Cessation of Payments: The Company may terminate Mr. Welch’s employment prior to the Termination Date and cease making all further payments and benefits set forth in this section) in the event that Mr. Welch is in violation of his material obligations under this Agreement, including, without limitation, the obligations set forth in Sections 1, 3, 4 and 6. However, Unica shall not take any adverse action relating to such violation until it provides Mr. Welch with written notice of the alleged violation, setting forth its basis for claiming an alleged violation, and provides Mr. Welch with at least five (5) business days to respond to such notice and/or cease and desist from any conduct alleged to constitute a violation. The cessation of payments under this Agreement is in addition to, and not in limitation of, all other equitable and legal remedies available to the Company, including, without limitation, injunctive relief and specific performance.

(l) Section 409A. The benefits received under this Transition Agreement are not considered “nonqualified deferred compensation” within the meaning of Internal Revenue Code Section 409A (“Section 409A”). Accordingly, no reporting under Section 409A is required. However, if the Company determines in the future that a Section 409A reporting is required for the consideration paid to Mr. Welch herein, it will notify Mr. Welch, in writing, in advance of said reporting.

3. Non-Disclosure, Non-Competition and Non-Solicitation Obligations. Mr. Welch acknowledges and reaffirms all of his post-employment obligations, consistent with applicable law, including, without limitation, the obligation to keep confidential and not to disclose any and all non-public information concerning the Company that he acquired during the course of his employment with the Company, such as any non-public information concerning the Company’s business affairs, business prospects and financial condition, as is stated more fully in the Non-Competition, Nondisclosure and Developments Agreement, he executed in May 2007 (the “Non-Compete Agreement”), which remains in full force and effect.

4. Return of Company Property. Mr. Welch confirms that, as of January 31, 2010, he will return to the Company all keys, files, records (and copies thereof), equipment (including, but not limited to, software and printers, wireless handheld devices, cellular phones, pagers, but not his computer as set forth in paragraph 2 (e)), Company identification, and any other Company-owned property in his possession or control, and that he will leave intact all electronic Company documents, including, but not limited to, those which he developed or helped develop during his employment.
