This Transition Agreement made as of this 8th day of April 2009 by and between
Unica Corporation (“Unica” or “Company”) and Eric Schnadig (“Mr. Schnadig”).

WHEREAS, Mr. Schnadig has been employed by the Company since August 1999, and
has served as the Company’s Senior Vice President of Worldwide Sales since
February 2006;

WHEREAS, the Company and Mr. Schnadig mutually desire to terminate
Mr. Schnadig’s employment with the Company and Mr. Schnadig 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. Schnadig will remain employed
as the Company’s Senior Vice President of Worldwide Sales from the date of this
Transition Agreement until his resignation as Senior Vice President of Worldwide
Sales on April 30, 2009 (the “Termination Date”). The parties further agree that
Mr. Schnadig will continue to perform those duties and responsibilities
customary and consistent with his position as Senior Vice President of Worldwide
Sales until the Termination Date. Up to and including the Termination Date,
Mr. Schnadig 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. Schnadig 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. Schnadig’s employment pursuant to
Section 1 above, Mr. Schnadig shall execute the Release of Claims attached
hereto as Exhibit A and, conditioned on the execution and nonrevocation by
Mr. Schnadig of the Release of Claims, Mr. Schnadig or, in the event of
Mr. Schnadig’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. Schnadig 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 $8,538.46, less
applicable taxes and withholdings, for a period of twelve (12) months. The total
gross amount of these payments is $220,000.

(c) Bonus Payment. In consideration for the promises made herein, Mr. Schnadig
will be eligible to receive incentive compensation for the fiscal year ending
September 30, 2009 in accordance with Mr. Schnadig’s previously executed fiscal
year 2009 Incentive Compensation Plan. Any incentive compensation paid to
Mr. Schnadig will be made in accordance with the Company’s normal bonus payment
practices, but in any event all incentive payments will be made prior to
December 31, 2009.

(d) 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. Schnadig,
provided that such services take place prior to April 30, 2010. Mr. Schnadig
shall instruct any such third party to invoice the Company directly for such
fees.

(e) Computer. The Company will allow Mr. Schnadig to keep the laptop computer
(and related peripherals) and BlackBerry device previously provided by the
Company. However, this transfer of ownership is contingent upon Mr. Schnadig’s
cooperation in allowing the Company to remove all Company programs, applications
and information from the computer and BlackBerry device prior to his termination
of employment. The Company transfers ownership of the computer (and related
peripherals) and BlackBerry device in “as is” condition and makes no promises
nor provides any warranties regarding the condition of the computer or
BlackBerry device. Mr. Schnadig will be responsible for obtaining cellular phone
and/or data service for the BlackBerry device after the Termination Date.

(f) Amended Equity Grants. The Company agrees to amend Mr. Schnadig’s
outstanding equity awards to provide for continued vesting beyond the
Termination Date in a pro rata amount up to and including September 30, 2009
(the “Vesting Date”) as follows:

  (i)   The award of 20,000 restricted stock units (“RSUs”) granted on
February 14, 2006 shall vest as to 20.83%, or 4,166 shares, on the Vesting Date;

  (ii)   The award of 20,000 RSUs granted on March 6, 2007 shall vest as to
20.83%, or 4,166 shares, on the Vesting Date;

  (iii)   The award of 12,500 RSUs granted on March 7, 2008 shall vest as to
20.83%, or 2,604 shares, on the Vesting Date;

  (iv)   The award of 30,000 RSUs granted on December 11, 2008 shall vest as to
20.83%, or 6,249 shares, on the Vesting Date;

  (v)   The award of 12,500 non-qualified stock options (“Stock Options”)
granted on March 7, 2008 shall vest as to 20.83%, or 2,604 shares, on the
Vesting Date;

  (vi)   The award of 10,500 Stock Options granted on December 11, 2008 shall
vest as to 20.83%, or 2,187 shares, on the Vesting Date;

  (vii)   The award of 26,666 Stock Options granted on February 26, 2009 shall
vest as to 29.16%, or 7,776 shares, on the Vesting Date;

  (viii)   The award of 53,333 Stock Options granted on February 26, 2009 shall
vest as to 19.44%, or 10,367 shares, on the Vesting Date; and

  (ix)   In addition, the period in which Mr. Schnadig may exercise any vested
non-qualified stock options shall be extended to be the period ending twelve
(12) months after the Termination Date.

Except as set forth above, all terms and conditions of any outstanding equity
award to Mr. Schnadig 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”), and all vesting in Company equity (e.g.
restricted stock units or options) will cease on the Vesting Date. In addition,
any amounts contributed by Mr. Schnadig under the Company’s Employee Stock
Purchase Plan for the current offering period shall be refunded to Mr. Schnadig
and included in the payment made to Mr. Schnadig 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. Schnadig 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 for the same period he is receiving payments under paragraph 2
(b) above (the “Payment Period”) or until he obtains comparable coverage from
other employment and completes any applicable insurance waiver or waiting
period, whichever occurs first. Mr. Schnadig still will be responsible for the
employee portion of the premium during the Payment Period and such amounts will
be deducted from the salary continuation payments.

(h) Leased Automobile. Effective upon the Termination Date, the Company will
assign to Mr. Schnadig the automobile lease related to Mr. Schnadig’s current
automobile and will pay Mr. Schnadig an additional amount equal to the aggregate
lease payments for the remainder of the lease term, which expires on August 22,
2009 (such amount referred to as the “Lease Amount”). If the Company is not
permitted to assign the automobile lease, then Mr. Schnadig will return the
automobile to the Company and the Company will pay Mr. Schnadig the Lease
Amount.

(i) 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. Schnadig’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. Schnadig is in violation of his
material obligations under this Agreement, including, without limitation, the
obligations set forth in Sections 1, 3, 4 and 6. 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. Schnadig
herein, it will notify Mr. Schnadig, in writing, in advance of said reporting.

3. Non-Disclosure, Non-Competition and Non-Solicitation Obligations.
Mr. Schnadig 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 on November 22, 1999 (the “Non-Compete Agreement”), which remains in
full force and effect.

4. Return of Company Property. Mr. Schnadig confirms that, as of April 30, 2009,
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 or BlackBerry
device as set forth in paragraph 2 (f)), 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. Mr. Schnadig agrees
that in the event that he discovers any other Company or proprietary materials
in his possession after the Termination Date, he will immediately return such
materials to the Company. Mr. Schnadig further agrees to cooperate with the
Company in cancelling all accounts for his benefit, if any, in the Company’s
name, including, but not limited to, credit cards, telephone charge cards,
cellular phone and/or pager accounts and computer accounts.

5. Mr. Schnadig’s Release of Claims. In consideration of the benefits provided
for in this Transition Agreement, which Mr. Schnadig acknowledges he would not
otherwise be entitled to receive, Mr. Schnadig hereby fully, forever,
irrevocably and unconditionally releases, remises and discharges the Company,
its officers, directors, stockholders, corporate affiliates, subsidiaries,
parent companies, agents and employees (each in their individual and corporate
capacities) (hereinafter, the “Released Parties”) from any and all claims,
charges, complaints, demands, actions, causes of action, suits, rights, debts,
sums of money, costs, accounts, reckonings, covenants, contracts, agreements,
promises, doings, omissions, damages, executions, obligations, liabilities, and
expenses (including attorneys’ fees and costs), of every kind and nature which
he ever had or now has against the Released Parties up to and including the date
of this Agreement, including, but not limited to, any claims arising out of his
employment with and/or separation from the Company, including, but not limited
to, all employment discrimination claims under Title VII of the Civil Rights Act
of 1964, 42 U.S.C. Section 2000 et seq., the Age Discrimination in Employment
Act, 29 U.S.C. Section 621 et seq., the Americans With Disabilities Act of 1990,

Income Security Act of 1974 (“ERISA”), 29 U.S.C. Section 1001 et seq., the
Massachusetts Fair Employment Practices Act., M.G.L. c. 151B, Section 1 et seq.,
the Massachusetts Civil Rights Act, M.G.L. c. 12, Sections 11H and 11I, the
