Company (individually, an "RSU" and collectively, the "RSUs"), subject to the
terms and conditions set forth in this Agreement and in the Company's 2005 Stock
Incentive Plan (the "Plan"). Each RSU represents the right to receive one share
of the common stock, $0.01 par value per share, of the Company ("Common Stock")
as provided in this Agreement. The shares of Common Stock that are issuable upon
vesting of the RSUs are referred to in this Agreement as "Shares."

      2. Vesting; Forfeiture.

            (a) This award shall vest as to 25% of the original number of RSUs
on December 1, 2006 and thereafter, as to 25% on December 1, 2007, 25% on
December 1, 2008 and 25% on December 1, 2009.

            (b) For purposes of this Agreement, employment with the Company
shall include employment with a parent or subsidiary of the Company.

            (c) If the Participant, prior to the final vesting date, violates
the non-competition, non-solicitation, assignment of inventions or
confidentiality provisions of any employment contract, assignment of inventions,
confidentiality and nondisclosure agreement or other agreement between the
Participant and the Company, upon written notice to the Participant from the
Company describing such violation, the Participant, in the sole discretion of
the Company, will return or (if not received) forfeit, to the Company, the
economic value of any award which is realized or obtained (measured at the date
of exercise, vesting, or payment) by such Participant during such period as
determined by the Company. The Company shall be entitled to set-off against the
amount of any such gain any amount owed by the Participant to the Company.

      3. Distribution of Shares.

            (a) The Company will distribute to the Participant (or to the
Participant's estate in the event that his or her death occurs after a vesting
date but before distribution of the corresponding Shares), as soon as
administratively practicable after each vesting date (each such date of
distribution is hereinafter referred to as a "Settlement Date"), the Shares of
Common Stock represented by RSUs that vested on such vesting date.

            (b) The Company shall not be obligated to issue to the Participant
the Shares upon the vesting of any RSU (or otherwise) unless the issuance and
delivery of such Shares shall comply with all relevant provisions of law and
other legal requirements including, without

<PAGE>

limitation, any applicable federal or state securities laws and the requirements
of any stock exchange upon which shares of Common Stock may then be listed.

      4. Restrictions on Transfer.

      The Participant shall not sell, assign, transfer, pledge, hypothecate or
otherwise dispose of, by operation of law or otherwise (collectively "transfer")
any RSUs, or any interest therein, except by will, trust, or the laws of descent
and distribution.

      5. Dividend and Other Shareholder Rights.

      Except as set forth in the Plan, neither the Participant nor any person
claiming under or through the Participant shall be, or have any rights or
privileges of, a stockholder of the Company in respect of the Shares issuable
pursuant to the RSUs granted hereunder until the Shares have been delivered to
the Participant.

      6. Provisions of the Plan; Reorganization Event.

            (a) This Agreement is subject to the provisions of the Plan, a copy
of which is furnished to the Participant with this Agreement.

            (b) Upon the occurrence of a Reorganization Event and/or a Change in
Control (as defined in the Plan), each RSU shall be subject to the vesting as
defined in the Plan and shall thereafter become the right to receive the cash,
securities or other property that a Share was converted into or exchanged for
pursuant to such Reorganization Event. If, in connection with a Reorganization
Event, a portion of the cash, securities and/or other property received upon the
conversion or exchange of the Shares is to be placed into escrow to secure
indemnification or similar obligations, the mix between the vested and unvested
portion of such cash, securities and/or other property that is placed into
escrow shall be the same as the mix between the vested and unvested portion of
such cash, securities and/or other property that is not subject to escrow.

      7. Withholding Taxes; Section 83(b) Election.

            (a) At each vesting date the Company will withhold and deduct from
the Participant that number of RSUs which is required to pay the Participant's
withholding obligation as determined by the Company.

            (b) The Participant acknowledges that no election under Section
83(b) of the Internal Revenue Code of 1986 may be filed with respect to this
award.

      8. Miscellaneous.

            (a) No Rights to Employment. The Participant acknowledges and agrees
that the vesting of the RSUs pursuant to Section 2 hereof is earned only by
continuing service as an employee at the will of the Company (not through the
act of being hired or purchasing shares hereunder). The Participant further
acknowledges and agrees that the transactions contemplated hereunder and the
vesting schedule set forth herein do not constitute an express or implied
promise of continued engagement as an employee or consultant for the vesting
period, for any

                                     - 2 -
<PAGE>

period, or at all.

            (b) Severability. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, and each other provision of this
Agreement shall be severable and enforceable to the extent permitted by law.

            (c) Waiver. Any provision for the benefit of the Company contained
in this Agreement may be waived, either generally or in any particular instance,
by the Board of Directors of the Company.

            (d) Binding Effect. This Agreement shall be binding upon and inure
to the benefit of the Company and the Participant and their respective heirs,
executors, administrators, legal representatives, successors and assigns,
subject to the restrictions on transfer set forth in Section 4 of this
Agreement.

            (e) Notice. All notices required or permitted hereunder shall be in

            (f) Pronouns. Whenever the context may require, any pronouns used in
this Agreement shall include the corresponding masculine, feminine or neuter
forms, and the singular form of nouns and pronouns shall include the plural, and
vice versa.

            (g) Entire Agreement. This Agreement and the Plan constitute the
entire agreement between the parties, and supersedes all prior agreements and
understandings, relating to the subject matter of this Agreement.

            (h) Amendment. This Agreement may be amended or modified only by a
written instrument executed by both the Company and the Participant.

            (i) Governing Law. This Agreement shall be construed, interpreted

                              TRANSITION AGREEMENT

      This Transition Agreement made as of this 31st day of January 2006 by and
between Unica Corporation ("Unica" or "Company") and Richard M. Darer ("Mr.
Darer").

      WHEREAS, Mr. Darer has served as the Company's Vice President and Chief
Financial Officer since March 2002;

      WHEREAS, Mr. Darer 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 duties to a new Vice
President and Chief Financial Officer.

      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. Darer will remain
employed as the Company's Vice President and Chief Financial Officer from the
date of this Transition Agreement until his resignation as Vice President and
Chief Financial Officer on February 28, 2006, thereafter will remain an employee
until his employment resignation on March 15, 2006 ("Contractual Period"). The
parties further agree that Mr. Darer will continue to perform those duties and
responsibilities customary and consistent with his position as Vice President
and Chief Financial Officer until February 28, 2006. From March 1, 2006 until
March 15, 2006, Mr. Darer will remain an employee of the Company, but will no
longer be Vice President and Chief Financial Officer. During this Contractual
Period, Mr. Darer will continue to receive the same base salary, fringe
benefits, and stock options vesting (including the March 11,2006 vesting) to
which he was entitled immediately prior to the execution date of this Transition
Agreement. In the event that the Company chooses a successor to Mr. Darer as
Vice President and Chief Financial Officer prior to February 28, 2006, Mr. Darer
agrees to immediately resign his position as Vice President and Chief Financial
Officer, as well as other positions with any subsidiary or affiliate of the
Company and he will assist the new Vice President and Chief Financial Officer
for the remainder of the Contractual Period. In the event that the Company
wishes to retain Mr. Darer's services after March 15, 2006 to assist in the
transition process, Mr. Darer agrees to do so under a mutually acceptable
consulting agreement, at a mutually agreed upon hourly rate of pay.

      2.  CONSIDERATION.

      (a) RELEASE. Upon the cessation of Mr. Darer's employment pursuant to
Section 1 above, Mr. Darer shall, no later than March 23, 2006, execute the
Release of Claims attached hereto as Exhibit A and, conditioned on the execution
and nonrevocation by Mr. Darer of the Release of Claims, Mr. Darer or, in the
event of Mr. Darer's death, his estate, shall be entitled to the compensation
and benefits set forth in subparagraphs 2(b)-(g) below.
<PAGE>
      (b) PAYMENTS. In consideration for the promises made herein, the Company
shall provide Mr. Darer 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 $8,083.84, less applicable taxes and
withholdings for a period of nine (9) months. The total gross amount of these
payments is $145,000.

      (c) BONUS PAYMENT(s). In consideration for the promises made herein, in
accordance with the terms, conditions and payment schedule of the Company's FY06
Executive Bonus Plan, Mr. Darer will receive payment for the Q1 bonus, provided
the Company meets its financial targets or the Board at its discretion awards
the bonus to other participants in the Executive Bonus Plan. In addition, in
lieu of a Q2 bonus, Mr. Darer will be eligible to receive a performance bonus of
$7,500 provided he competently performs his duties pursuant to this Transition
Agreement and, if applicable, successfully transfers his duties to a successor
as assessed by Carol Dane, Vice-President, Human Resources, in her sole
discretion. If earned as determined by Ms. Dane, Mr. Darer will receive this
bonus payment on March 16, 2006.

      (d) EXECUTIVE TRANSITION SERVICES. In order to provide you with the
identification of your next professional opportunity, the Company will provide
you with up to $3,000 of executive services through Transition Solutions,
provided the services are completed and paid by December 1, 2006.

      (e) EDUCATIONAL REIMBURSEMENT. The Company will reimburse Mr. Darer for up
to $2,000 in tuition reimbursement for executive education coursework of his
choice, provided the coursework is completed and the expense reimbursement claim
received by the Company on or before September 30, 2006.

      (f) HOME COMPUTER. The Company will allow Mr. Darer to keep his current
home computer provided he allows the Company to remove all Company programs,
applications and information from the computer prior to his termination of
employment.

      (g) HEALTH AND DENTAL INSURANCE. The date Mr. Darer's employment with the
Company terminates pursuant to this Transition Agreement, March 15, 2006 (the
"Termination Date") will serve as the "qualifying event" under the Consolidated
Omnibus Budget Reconciliation Act of 1985 ("COBRA"). If he 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
other employment and completes any applicable insurance waiver or waiting
period, whichever occurs first. Mr. Darer still will be responsible for the
employee portion of the premium during the Payment Period and such amounts will
be deducted from the payments.

      (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.

and long term disability, will end upon the Termination Date.

      (j) 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.
Darer herein, it will notify Mr. Darer, in writing, in advance of said
reporting.

      3. NON-DISCLOSURE, NON-COMPETITION AND NON-SOLICITATION OBLIGATIONS. Mr.
Darer acknowledges and reaffirms all of his obligations, consistent with
applicable law, 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, including, but not limited to, 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 March 11, 2002 (the
"Non-Compete Agreement"), which remains in full force and effect.

      4. RETURN OF COMPANY PROPERTY. Mr. Darer confirms that, as of March 15,
2006, 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 (f)), Company identification, Company vehicles 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. Darer
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 Ms. Dane at the Company. Mr. Darer further confirms

Company's name, including, but not limited to, credit cards, telephone charge
cards, cellular phone and/or pager accounts and computer accounts.

not otherwise be entitled to receive, Mr. Darer hereby fully, forever,
irrevocably and unconditionally releases, remises and discharges the Company,
its officers, directors, stockholders, corporate affiliates, subsidiaries,
