                                UNICA CORPORATION

                            2005 STOCK INCENTIVE PLAN
                 (Amended and restated as of February 14, 2006)

1.    Purpose

      The purpose of this 2005 Stock Incentive Plan (the "Plan") of Unica
Corporation, a Delaware corporation (the "Company"), is to advance the interests
of the Company's stockholders by enhancing the Company's ability to attract,
retain and motivate persons who are expected to make important contributions to
the Company and by providing such persons with equity ownership opportunities
and performance-based incentives that are intended to align their interests with
those of the Company's stockholders. Except where the context otherwise
requires, the term "Company" shall include any of the Company's present or
future parent or subsidiary corporations as defined in Section 424(e) or (f) of
the Internal Revenue Code of 1986, as amended, and any regulations promulgated
thereunder (the "Code") and any other business venture (including any joint
venture or limited liability company) in which the Company has a controlling
interest, as determined by the Board of Directors of the Company (the "Board").

2.    Eligibility

      All of the Company's employees, officers, directors, consultants and
advisors are eligible to receive options, stock appreciation rights, restricted
stock and other stock-based awards (each, an "Award") under the Plan. Each
person who receives an Award under the Plan is deemed a "Participant."

3.    Administration and Delegation

      (a)   Administration by Board. The Plan will be administered by the Board.
The Board shall have authority to grant Awards and to adopt, amend and repeal
such administrative rules, guidelines and practices relating to the Plan as it
shall deem advisable. The Board may correct any defect, supply any omission or
reconcile any inconsistency in the Plan or any Award in the manner and to the
extent it shall deem expedient to carry the Plan into effect and it shall be the
sole and final judge of such expediency. All decisions by the Board shall be
made in the Board's sole discretion and shall be final and binding on all
persons having or claiming any interest in the Plan or in any Award. No director
or person acting pursuant to the authority delegated by the Board shall be
liable for any action or determination relating to or under the Plan made in
good faith.

      (b)   Appointment of Committees. To the extent permitted by applicable
law, the Board may delegate any or all of its powers under the Plan to one or
more committees or subcommittees of the Board (a "Committee"). All references in
the Plan to the "Board" shall mean the Board or a Committee of the Board or the
officers referred to in Section 3(c) to the extent that the Board's powers or
authority under the Plan have been delegated to such Committee or officers.

      (c)   Delegation to Officers. To the extent permitted by applicable law,
the Board may delegate to one or more officers of the Company the power to grant
Awards to employees or officers of the Company or any of its present or future
subsidiary corporations and to exercise such other powers under the Plan as the
Board may determine, provided that the Board shall fix the terms of the Awards
to be granted by such officers (including the exercise price of such Awards,
which may include a formula by which the exercise price will be determined) and
the maximum number of shares subject to Awards that the officers may grant;
provided further that no officer shall be authorized to grant Awards to any
"executive officer" of
<PAGE>
the Company (as defined by Rule 3b-7 under the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) or to any "officer" of the Company (as defined
by Rule 16a-1 under the Exchange Act).

4.    Stock Available for Awards

      (a)   Number of Shares. Subject to adjustment under Section 9, Awards may
be made under the Plan for up to the number of shares of common stock, $0.01 par
value per share, of the Company (the "Common Stock") that is equal to the sum
of:

            (i)   1,500,000 shares of Common Stock; plus

            (ii)  such additional number of shares of Common Stock (up to
                  4,000,000 shares) as is equal to the sum of (x) the number of
                  shares of Common Stock reserved for issuance under the
                  Company's 2003 Stock Option Plan (the "Existing Plan") that
                  remain available for grant under the Existing Plan immediately
                  prior to the closing of the Company's initial public offering
                  and (y) the number of shares of Common Stock subject to awards
                  granted under the Existing Plan which awards expire, terminate
                  or are otherwise surrendered, canceled, forfeited or
                  repurchased by the Company at their original issuance price
                  pursuant to a contractual repurchase right (subject, however,
                  in the case of Incentive Stock Options (as hereinafter
                  defined) to any limitations of the Code); plus

            (iii) an annual increase to be added on the first day of each of the
                  Company's fiscal years during the period beginning in fiscal
                  year 2006 and ending on the second day of fiscal year 2014
                  equal to the least of (A) 5,000,000 shares of Common Stock,
                  (B) 5% of the outstanding shares of Common Stock as of the
                  opening of business on such date or (C) an amount determined
                  by the Board.

      If any Award expires or is terminated, surrendered or canceled without
having been fully exercised or is forfeited in whole or in part (including as
the result of shares of Common Stock subject to such Award being repurchased by
the Company at the original issuance price pursuant to a contractual repurchase
right) or results in any Common Stock not being issued, the unused Common Stock
covered by such Award shall again be available for the grant of Awards under the
Plan. Further, shares of Common Stock tendered to the Company by a Participant
to exercise an Award shall be added to the number of shares of Common Stock
available for the grant of Awards under the Plan. In the case of Incentive Stock
Options, however, the foregoing provisions shall be subject to any limitations
under the Code. Shares issued under the Plan may consist in whole or in part of
authorized but unissued shares or treasury shares.

      (b)   Sub-Limits. Subject to adjustment under Section 9, the following
sub-limits on the number of shares subject to Awards shall apply:

            (i)   Section 162(m) Per-Participant Limit. For Awards granted after
                  the Common Stock is registered under the Securities Exchange
                  Act of 1934 (the "Exchange Act"), the maximum number of shares
                  of Common Stock with respect to which Awards may be granted to
                  any Participant under the Plan shall be 1,500,000 per calendar
                  year. For purposes of the foregoing limit, the combination of
                  an Option in tandem with an SAR (each as hereinafter defined)
                  shall be treated as a single Award. The per-Participant limit
                  described in this Section 4(b)(i) shall be construed and
                  applied consistently with Section 162(m) of the Code or any
                  successor provision thereto, and the regulations thereunder
                  ("Section 162(m)").

                                     - 2 -
<PAGE>
            (ii)  Limits on Awards other than Options and SARs. The maximum
                  number of shares with respect to Awards other than Options and
                  SARs that may be granted shall be equal to the sum of: (i)
                  750,000 plus (ii) a number of shares equal to 50% of the
                  aggregate increase effected from time to time pursuant to
                  Section 4(a)(iii).

5.    Stock Options

      (a)   General. The Board may grant options to purchase Common Stock (each,
an "Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option that is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option."

      (b)   Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company, any of the
Company's present or future parent or subsidiary corporations as defined in
Section 424(e) or (f) of the Code, and any other entities the employees of which
are eligible to receive Incentive Stock Options under the Code, and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) that is intended to be an
Incentive Stock Option is not an Incentive Stock Option or for any action taken
by the Board pursuant to Section 10(f), including the conversion of an Incentive
Stock Option to a Nonstatutory Stock Option.

      (c)   Exercise Price. The Board shall establish the exercise price of each
Option and specify such exercise price in the applicable option agreement.

      (d)   Duration of Options. Each Option shall be exercisable at such times
and subject to such terms and conditions as the Board may specify in the
applicable option agreement, provided that no Option shall be granted for a term
in excess of 10 years.

      (e)   Exercise of Option. Options may be exercised by delivery to the
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised. Shares of Common Stock subject to the
Option will be delivered by the Company following exercise either as soon as
practicable or, subject to such conditions as the Board shall specify, on a
deferred basis (with the Company's obligation to be evidenced by an instrument
providing for future delivery of the deferred shares at the time or times
specified by the Board).

      (f)   Payment Upon Exercise. Common Stock purchased upon the exercise of
an Option granted under the Plan shall be paid for as follows:

            (i)   in cash or by check, payable to the order of the Company;

            (ii)  except as the Board may otherwise provide in an option
                  agreement, by:

                  (A)   delivery of an irrevocable and unconditional undertaking
                        by a creditworthy broker to deliver promptly to the
                        Company sufficient funds to pay the exercise price and
                        any required tax withholding, or

                  (B)   delivery by the Participant to the Company of a copy of
                        irrevocable and unconditional instructions to a
                        creditworthy broker to deliver promptly to the

                                     - 3 -
<PAGE>
                        Company cash or a check sufficient to pay the exercise
                        price and any required tax withholding;

            (iii) when the Common Stock is registered under the Exchange Act, by
                  delivery of shares of Common Stock owned by the Participant
                  valued at their fair market value as determined by (or in a
                  manner approved by) the Board ("Fair Market Value"), provided:

                  (A)   such method of payment is then permitted under
                        applicable law,

                  (B)   such Common Stock, if acquired directly from the
                        Company, was owned by the Participant for the minimum
                        period of time, if any, as may be established by the
                        Board in its discretion, which minimum shall be, in the
                        absence of a determination by the Board to the contrary,
                        six months, and

                  (C)   such Common Stock is not subject to any repurchase,
                        forfeiture, unfulfilled vesting or other similar
                        requirements;

            (iv)  to the extent permitted by applicable law (including the
                  Sarbanes-Oxley Act of 2002) and by the Board, by:

                  (A)   delivery of a promissory note of the Participant to the
                        Company on terms determined by the Board, or

                  (B)   payment of such other lawful consideration as the Board
                        may determine; or

            (v)   by any combination of the above permitted forms of
                  payment.

      (g)   Substitute Options. In connection with a merger or consolidation of
an entity with the Company or the acquisition by the Company of property or
stock of an entity, the Board may grant Options in substitution for any options
or other stock or stock-based awards granted by such entity or an affiliate
thereof. Substitute Options may be granted on such terms as the Board deems
appropriate in the circumstances, notwithstanding any limitations on Options
contained in Section 2 or elsewhere in this Section 5.

      (h)   Repricing. The Board may, without stockholder approval, amend any
outstanding Option granted under the Plan to provide an exercise price per share
that is lower than the then-current exercise price per share of such outstanding
Option. The Board may also, without stockholder approval, cancel any outstanding
Option and grant in substitution therefor new Options covering the same or a
different number of shares of Common Stock and having an exercise price per
share lower than the then-current exercise price per share of the cancelled
Option.

6.    Stock Appreciation Rights

      (a)   Nature of Stock Appreciation Rights. A Stock Appreciation Right
("SAR") is an Award entitling the holder on exercise to receive an amount in
cash or Common Stock or a combination thereof (such form to be determined by the
Board) determined in whole or in part by reference to appreciation, from and
after the date of grant, in the fair market value of a share of Common Stock.
SARs may be based solely on appreciation in the fair market value of Common
Stock or on a comparison of such appreciation with some other measure of market
growth such as (but not limited to) appreciation in a recognized market index.
The date as of which such appreciation or other measure is determined shall be

Options granted under the Plan.

            (i)   Rules Applicable to Tandem Awards. When SARs are expressly
                  granted in tandem with Options:

                  (A)   the SAR will be exercisable only at such time or times,
                        and to the extent, that the related Option is
                        exercisable (except to the extent designated by the
                        Board in connection with a Reorganization Event or a
                        Change in Control Event) and will be exercisable in
                        accordance with the procedure required for exercise of
                        the related Option;

                  (B)   the SAR will terminate and no longer be exercisable upon
                        the termination or exercise of the related Option,
                        except to the extent designated by the Board in
                        connection with a Reorganization Event or a Change in
                        Control Event and except that a SAR granted with respect
                        to less than the full number of shares covered by an
                        Option will not be reduced until the number of shares as
                        to which the related Option has been exercised or has
                        terminated exceeds the number of shares not covered by
                        the SAR;

                  (C)   the Option will terminate and no longer be exercisable
                        upon the exercise of the related SAR; and

                  (D)   the SAR will be transferable only with the related
                        Option.

            (ii)  Exercise of Independent Stock Appreciation Rights. A SAR not
                  expressly granted in tandem with an Option will become
                  exercisable at such time or times, and on such conditions, as
                  the Board may specify in the SAR Award.

      (c)   Exercise. A SAR may be exercised only by delivery to the Company of

7.    Restricted Stock; Restricted Stock Units

      (a)   Grants. The Board may grant Awards entitling recipients to acquire
shares of Common Stock ("Restricted Stock"), subject to the right of the Company
to repurchase all or part of such shares at their issue price or other stated or
formula price (or to require forfeiture of such shares if issued at no cost)
from the recipient in the event that conditions specified by the Board in the
applicable Award are not satisfied prior to the end of the applicable
restriction period or periods established by the Board for such Award. Instead
of granting Awards for Restricted Stock, the Board may grant Awards entitling
the recipient to receive shares of Common Stock to be delivered in the future
("Restricted Stock Units") subject to such terms and conditions on the delivery
of the shares of Common Stock as the Board shall determine (each Award for
Restricted Stock or Restricted Stock Units, a "Restricted Stock Award"). The
Board may also permit an exchange of unvested shares of Common Stock that have
already been delivered to a Participant for an instrument evidencing the right
to future delivery of Common Stock at such time or times, and on such
conditions, as the Board shall specify.

      (b)   Terms and Conditions. The Board shall determine the terms and
conditions of a Restricted Stock Award, including the conditions for repurchase
(or forfeiture) and the issue price, if any.

      (c)   Stock Certificates. Any stock certificates issued in respect of a
Restricted Stock Award, if applicable, shall be registered in the name of the
Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or the Designated Beneficiary of such
Participant. For these purposes, a "Designated Beneficiary" of a Participant
shall be (1) a beneficiary designated by such Participant, in a manner
determined by the Board, to receive amounts due or exercise rights of such
Participant in the event of such Participant's death or (2) in the absence of
such a designation, the Participant's estate.

      (d)   Deferred Delivery of Shares. The Board may, at the time any
Restricted Stock Award is granted, provide that, at the time Common Stock would
otherwise be delivered pursuant to the Award, the Participant shall instead
receive an instrument evidencing the right to future delivery of Common Stock at
such time or times, and on such conditions, as the Board shall specify. The
Board may at any time accelerate the time at which delivery of all or any part
of the Common Stock shall take place. The Board may also permit an exchange of
unvested shares of Common Stock that have already been delivered to a
Participant for an instrument evidencing the right to future delivery of Common
Stock at such time or times, and on such conditions, as the Board shall specify.

8.    Other Stock-Based Awards

      Other Awards of shares of Common Stock, and other Awards that are valued
in whole or in part by reference to, or are otherwise based on, shares of Common
Stock or other property, may be granted hereunder to Participants ("Other Stock
Unit Awards"), including Awards entitling recipients to receive shares of Common
Stock to be delivered in the future. Such Other Stock Unit Awards shall also be
available as a form of payment in the settlement of other Awards granted under
the Plan or as payment in lieu of compensation to which a Participant is
otherwise entitled. Other Stock Unit Awards may be paid in shares of Common
Stock or cash, as the Board shall determine. Subject to the provisions of the
Plan, the Board shall determine the conditions of each Other Stock Unit Awards,
including any purchase price applicable thereto. At the time any Award is
granted, the Board may provide that, at the time Common Stock would otherwise be
delivered pursuant to the Award, the Participant will instead receive an
instrument evidencing the Participant's right to future delivery of the Common
Stock.

9.    Adjustments for Changes in Common Stock and Certain Other Events

      (a)   Changes in Capitalization. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than an ordinary
cash dividend:

            (i)   the number and class of securities available under this Plan;

            (ii)  the pre-Participant limit set forth in Section 4(b);

            (iii) the number and class of securities and exercise price per
                  share of each outstanding Option;

            (iv)  the share and per-share provisions of each SAR,

            (v)   the repurchase price per share subject to each outstanding
                  Restricted Stock Award; and

            (vi)  the share- and per-share-related provisions of each
                  outstanding SAR and Other Stock Unit Award,

shall be appropriately adjusted by the Company (or substituted Awards may be
made, if applicable) to the extent determined by the Board.

            (ii)  Effect on Options

                  (A)   Reorganization Event. Upon the occurrence of a
            Reorganization Event (regardless of whether such event also
            constitutes a Change in Control Event), or the execution by the
            Company of any agreement with respect to a Reorganization Event
            (regardless of whether such event will result in a Change in Control
            Event), the Board shall provide that all outstanding Options shall
            be assumed, or equivalent options shall be substituted, by the
            acquiring or succeeding corporation (or an affiliate thereof);
            provided that if such Reorganization Event also constitutes a Change
            in Control Event, except to the extent specifically provided to the

                                     - 8 -

            contrary in the instrument evidencing any Option or any other
            agreement between a Participant and the Company:

                        (1)   25% of the number of shares subject to the Option
                              that were not already vested shall be exercisable
                              upon the occurrence of such Reorganization Event
                              and, subject to the following clause (2), the
                              remaining 75% of such number of shares shall
                              continue to become vested in accordance with the
                              original vesting schedule set forth in such
                              option, with 75% of the number of shares that
                              would otherwise have become vested on each
                              subsequent vesting date in accordance with the
                              original schedule becoming vested on each
                              subsequent vesting date, and

                        (2)   25% of the number of shares subject to the Option
                              that were not already vested shall become
                              immediately exercisable if, on or prior to the
                              first anniversary of the date of the consummation
                              of the Reorganization Event, the Participant's
                              employment with the Company or the acquiring or
                              succeeding corporation is terminated for Good
                              Reason by the Participant or is terminated without
                              Cause by the Company or the acquiring or
                              succeeding corporation.

                  For purposes hereof, an Option shall be considered to be
            assumed if, following consummation of the Reorganization Event, the
            Option confers the right to purchase, for each share of Common Stock
            subject to the Option immediately prior to the consummation of the
            Reorganization Event, the consideration (whether cash, securities or
            other property) received as a result of the Reorganization Event by
            holders of Common Stock for each share of Common Stock held
            immediately prior to the consummation of the Reorganization Event
            (and if holders were offered a choice of consideration, the type of
            consideration chosen by the holders of a majority of the outstanding
            shares of Common Stock); provided that if the consideration received
            as a result of the Reorganization Event is not solely common stock
            of the acquiring or succeeding corporation (or an affiliate
            thereof), the Company may, with the consent of the acquiring or
            succeeding corporation, provide for the consideration to be received
            upon the exercise of Options to consist solely of common stock of
            the acquiring or succeeding corporation (or an affiliate thereof)
            equivalent in fair market value to the per share consideration
            received by holders of outstanding shares of Common Stock as a
            result of the Reorganization Event.

                  Notwithstanding the foregoing, if the acquiring or succeeding
            corporation (or an affiliate thereof) does not agree to assume, or
            substitute for, such Options, or in the event of a liquidation or
            dissolution of the Company, the Board shall, upon written notice to
            the Participants, provide that all then unexercised Options will
            become exercisable in full as of a specified time prior to the
            Reorganization Event and will terminate immediately prior to the
            consummation of such Reorganization Event, except to the extent
            exercised by the Participants before the consummation of such
            Reorganization Event; provided that in the event of a Reorganization
            Event under the terms of which holders of Common Stock will receive
            upon consummation thereof a cash payment for each share of Common
            Stock surrendered pursuant to such Reorganization Event (the
            "Acquisition Price"), then the Board may instead provide that all
            outstanding Options shall terminate upon consummation of such
            Reorganization Event and that each Participant shall receive, in
            exchange therefor, a cash payment equal to the amount (if any) by
            which (1) the Acquisition Price multiplied by the number of shares
            of Common Stock subject to such outstanding Options (whether or not
            then exercisable), exceeds (2) the aggregate exercise price of such
            Options. To the extent all or any portion of an Option becomes
            exercisable solely as a result of the first sentence of this
            paragraph, upon exercise of

                                     - 9 -
<PAGE>
            such Option the Participant shall receive shares subject to a right
            of repurchase by the Company or its successor at the Option exercise
            price. Such repurchase right (x) shall lapse at the same rate as the
            Option would have become exercisable under its terms and (y) shall
            not apply to any shares subject to the Option that were exercisable
            under the Option's terms without regard to the first sentence of
            this paragraph.

                  (B)   Change in Control Event that is not a Reorganization
            Event. Upon the occurrence of a Change in Control Event that does
            not also constitute a Reorganization Event, except to the extent
            specifically provided to the contrary in the instrument evidencing
            any Option or any other agreement between a Participant and the
            Company, the vesting schedule of such Option shall be accelerated in
            part so that 25% of the number of shares that would otherwise have
            first become vested on any date after the date of the Change in
            Control Event shall immediately become exercisable. The remaining
            shares subject to such Option shall continue to become vested in
            accordance with the original vesting schedule set forth in such
            Option, such that 75% of the number of shares that would otherwise
            have become vested on any subsequent vesting date in accordance with
            the original schedule shall become vested on such subsequent vesting
            date. Notwithstanding the foregoing, if, on or prior to the first
            anniversary of the date of the consummation of a Change in Control
            Event that does not also constitute a Reorganization Event, the
            Participant's employment with the Company or the acquiring or
            succeeding corporation is terminated for Good Reason by the
            Participant or is terminated without Cause by the Company or the
            acquiring or succeeding corporation, then additional shares subject
            to each Option held by the Participant shall immediately become
            exercisable in a number equal to the lesser of (i) the aggregate
            number of shares that became immediately exercisable under such
            Option upon the occurrence of the Change in Control Event (that is,
            a number of shares equal to 25% of the aggregate number of shares
            that were not vested under such Option as of the time immediately
            prior to the Change in Control Event) and (ii) the aggregate number
            of shares that are not vested under such Option as of the time
            immediately prior to such termination.

            (iii) Effect on Restricted Stock Awards

                  (A)   Reorganization Event that is not a Change in Control
            Event. Upon the occurrence of a Reorganization Event that is not a
            Change in Control Event, the repurchase and other rights of the
            Company under each outstanding Restricted Stock Award shall inure to
            the benefit of the Company's successor and shall apply to the cash,
            securities or other property that the Common Stock was converted
            into or exchanged for pursuant to such Reorganization Event in the
            same manner and to the same extent as they applied to the Common
            Stock subject to such Restricted Stock Award.

                  (B)   Change in Control Event. Upon the occurrence of a Change
            in Control Event (regardless of whether such event also constitutes
            a Reorganization Event), except to the extent specifically provided
            to the contrary in the instrument evidencing any Restricted Stock
            Award or any other agreement between a Participant and the Company,
            the vesting schedule of all Restricted Stock Awards shall be
            accelerated in part so that 25% of the number of shares that would
            otherwise have first become free from conditions or restrictions on
            any date after the date of the Change in Control Event shall
            immediately become free from conditions or restrictions. The
            remaining shares subject to such Restricted Stock Award shall
            continue to become free from conditions or restrictions in
            accordance with the original schedule set forth in such Restricted
            Stock Award, such that 75% of the number of shares that would
            otherwise have become free from conditions or restrictions on any
            subsequent vesting date in accordance with the original schedule
            shall become free from conditions or restrictions on such subsequent

                                     - 10 -
<PAGE>
            vesting date. Notwithstanding the foregoing, if, on or prior to the
            first anniversary of the date of the consummation of a Change in
            Control Event, the Participant's employment with the Company or the
            acquiring or succeeding corporation is terminated for Good Reason by
            the Participant or is terminated without Cause by the Company or the
            acquiring or succeeding corporation, then additional shares subject
            to each Restricted Stock Award held by the Participant shall become
            free from all conditions and restrictions in a number equal to the
            lesser of (i) the aggregate number of shares that became free of
            conditions and restrictions under such Restricted Stock Award upon
            the occurrence of the Change in Control Event (that is, a number of
            shares equal to 25% of the aggregate number of shares that were not
            free of conditions and restrictions as of the time immediately prior
            to the Change in Control Event) and (ii) the aggregate number of
            shares that are not free of conditions and restrictions under such
            Restricted Stock Award as of the time immediately prior to such
            termination.

            (iv)  Effect on Other Stock Unit Awards. The Board may specify in an
      Award at the time of the grant the effect of a Reorganization Event and
      Change in Control Event on any Other Stock Unit Award.

10.   General Provisions Applicable to Awards

      (a)   Transferability of Awards. Except as the Board may otherwise
determine or provide in an Award, Awards shall not be sold, assigned,
transferred, pledged or otherwise encumbered by the person to whom they are
granted, either voluntarily or by operation of law, except by will or the laws
of descent and distribution or, other than in the case of an Incentive Stock
Option, pursuant to a qualified domestic relations order, and, during the life
of the Participant, shall be exercisable only by the Participant. References to
a Participant, to the extent relevant in the context, shall include references
to authorized transferees.

      (b)   Documentation. Each Award shall be evidenced in such form (written,
electronic or otherwise) as the Board shall determine. Each Award may contain
terms and conditions in addition to those set forth in the Plan.

      (c)   Board Discretion. Except as otherwise provided by the Plan, each
Award may be made alone or in addition or in relation to any other Award. The
terms of each Award need not be identical, and the Board need not treat
Participants uniformly.

      (d)   Termination of Status. The Board shall determine the effect on an
            Award of the disability, death, retirement, authorized leave of
absence or other change in the employment or other status of a Participant and
the extent to which, and the period during which, the Participant, or the
Participant's legal representative, conservator, guardian or Designated
Beneficiary, may exercise rights under the Award.

      (e)   Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Company for payment of, any taxes required by law
to be withheld in connection with an Award to such Participant. Except as the
Board may otherwise provide in an Award, for so long as the Common Stock is
registered under the Exchange Act, Participants may satisfy such tax obligations
in whole or in part by delivery of shares of Common Stock, including shares
retained from the Award creating the tax obligation, valued at their Fair Market
Value; provided that, except as otherwise provided by the Board, the total tax
withholding where stock is being used to satisfy such tax obligations cannot
exceed the Company's minimum statutory withholding obligations (based on minimum
statutory withholding rates for federal and state tax purposes, including
payroll taxes, that are applicable to such supplemental taxable income). Shares
surrendered to satisfy tax withholding requirements cannot be subject to any
repurchase, forfeiture, unfulfilled vesting or other similar requirements. The
Company may, to the extent

                                     - 11 -
<PAGE>
permitted by law, deduct any such tax obligations from any payment of any kind
otherwise due to a Participant.

      (f)   Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including substituting therefor another Award of the same or
a different type, changing the date of exercise or realization, and converting
an Incentive Stock Option to a Nonstatutory Stock Option, provided that the
Participant's consent to such action shall be required unless the Board
determines that the action, taking into account any related action, would not
materially and adversely affect the Participant.

      (g)   Conditions on Delivery of Stock. The Company will not be obligated
to deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until:

            (i)   all conditions of the Award have been met or removed to the
                  satisfaction of the Company,

            (ii)  in the opinion of the Company's counsel, all other legal
                  matters in connection with the issuance and delivery of such
                  shares have been satisfied, including any applicable
                  securities laws and any applicable stock exchange or stock
                  market rules and regulations, and

            (iii) the Participant has executed and delivered to the Company such
                  representations or agreements as the Company may consider
                  appropriate to satisfy the requirements of any applicable
                  laws, rules or regulations.

      (h)   Acceleration. The Board may at any time provide that any Award shall
become immediately exercisable in full or in part, free of some or all
restrictions or conditions, or otherwise realizable in full or in part, as the
case may be.

      (i)   Performance Conditions.

            (i)   This Section 10(i) shall be administered by a Committee
      approved by the Board, all of the members of which are "outside directors"
      as defined by Section 162(m) (the "Section 162(m) Committee").

            (ii)  Notwithstanding any other provision of the Plan, if the
      Section 162(m) Committee determines at the time an Award is granted to a
      Participant who is then an officer, that such Participant is, or is likely
      to be as of the end of the tax year in which the Company would claim a tax
      deduction in connection with such Award, a Covered Employee (as defined in
      Section 162(m)), then the Section 162(m) Committee may provide that this
      Section 9(i) is applicable to such Award.

            (iii) If an Award is subject to this Section 10(i), than the lapsing
      of restrictions thereon and the distribution of cash or Shares pursuant
      thereto, as applicable, shall be subject to the achievement of one or more
      objective performance goals established by the Section 162(m) Committee,
      which:

                  (A)   shall be set by the Section 162(m) Committee within the
                        time period prescribed by, and shall otherwise comply
                        with the requirements of, Section 162(m);

                  (B)   shall be based on the attainment of specified levels of
                        one or any combination of the following: (i) new
                        bookings, (ii) revenue, (iii) revenue growth, (iv)
                        expenses, (v) operating or gross margin, (vi) net
                        operating profit after tax, (vii) pre-tax or

                                     - 12 -
<PAGE>
                        after-tax earnings, (viii) earnings growth, (ix)
                        earnings per share, (x) total shareholder return, (xi)
                        return on sales, assets, equity or investment, (xii)
                        return on average equity or average assets with respect
                        to a pre-determined peer group, (xiii) achievement of
                        balance sheet or income statement objectives, (xiv) cash
                        flow, (xv) operating cash flow, (xvi) stock price,
                        (xvii) market share, (xviii) regulatory compliance,
                        (xix) improvement of financial ratings or (xx) such
                        other objective goals as are established by the Board;

                  (C)   may be absolute in their terms or measured against or in
                        relationship to other companies comparably, similarly or
                        otherwise situated;

                  (D)   may be adjusted to exclude any one or more of (i)
                        extraordinary items, (ii) gains or losses on the
                        dispositions of discontinued operations, (iii) the
                        cumulative effects of changes in accounting principles,
                        (iv) the writedown of any asset and (v) charges for
                        restructuring and rationalization programs; and

                  (E)   may vary by Participant and may be different for
                        different Awards.

            (iv)  Notwithstanding any provision of the Plan, with respect to any
      Award that is subject to this Section 10(i), the Section 162(m) Committee:

                  (A)   may adjust downwards, but not upwards, the cash or
                        number of Shares payable pursuant to such Award; and

                  (B)   may not waive the achievement of the applicable
                        performance goals except in the case of the death or
                        disability of the Participant.

            (v)   The Section 162(m) Committee shall have the power to impose
      such other restrictions on Awards subject to this Section 10(i) as it may
      deem necessary or appropriate to ensure that such Awards satisfy all
      requirements for "performance-based compensation" within the meaning of
      Section 162(m)(4)(C) of the Code, or any successor provision thereto.

11.   General

      (a)   No Right To Employment or Other Status. No person shall have any
claim or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

      (b)   No Rights As Stockholder. Subject to the provisions of the
applicable Award, no Participant or Designated Beneficiary shall have any rights
as a stockholder with respect to any shares of Common Stock to be distributed
with respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

                                     - 13 -
<PAGE>
      (c)   Effective Date and Term of Plan. The Plan shall take effect upon the
execution and delivery of an underwriting agreement for the initial public
offering of shares of Common Stock in a firm commitment underwriting, subject to
approval by the stockholders of the Company as required by the Code, which
approval must occur within twelve months of the adoption of the Plan by the
Board. No Awards shall be granted under the Plan after the tenth anniversary of
the date on which the Plan was adopted by the Board, but Awards previously
granted may extend beyond that date.

      (d)   Amendment of Plan. The Board may amend, suspend or terminate the
Plan or any portion thereof at any time; provided that, to the extent determined
by the Board, no amendment requiring stockholder approval under any applicable
legal, regulatory or listing requirement shall become effective until such
stockholder approval is obtained. No Award shall be made that is conditioned
upon stockholder approval of any amendment to the Plan.

      (e)   Authorization of Sub-Plans. The Board may from time to time
establish one or more sub-plans under the Plan for purposes of satisfying
applicable blue sky, securities or tax laws of various jurisdictions. The Board
shall establish such sub-plans by adopting supplements to this Plan containing
(i) such limitations on the Board's discretion under the Plan as the Board deems
necessary or desirable or (ii) such additional terms and conditions not
otherwise inconsistent with the Plan as the Board shall deem necessary or
desirable. All supplements adopted by the Board shall be deemed to be part of
the Plan, but each supplement shall apply only to Participants within the
affected jurisdiction and the Company shall not be required to provide copies of
any supplement to Participants in any jurisdiction which is not the subject of
such supplement.

      (f)   Provisions for Foreign Participants. The Board may modify Awards or
Options granted to Participants who are foreign nationals or employed outside
the United States or establish subplans or procedures under the Plan to
recognize differences in laws, rules, regulations or customs of such foreign
jurisdictions with respect to tax, securities, currency, employee benefit or
other matters.

      (g)   Governing Law. The provisions of the Plan and all Awards made
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware (without reference to the conflicts of laws provisions
thereof).

      (h)   Construction. The headings of the Sections of this Plan are included
only for convenience and shall not affect the meaning or interpretation of this
Plan. References herein to Sections shall mean such Sections of this Agreement,
except as otherwise specified. The words "herein" and "hereof" and other words
of similar import refer to this Plan as a whole and not to any particular part
of this Plan. The word "including" as used herein shall not be construed so as
to exclude any other thing not referred to or described.

             Amended by the Board of Directors and Shareholders on July 20, 2006
