     determined by the Committee, provided that, the exercise price per Share of
     any Incentive Stock Option shall not be less than 100% of the Fair Market
     Value of a Share as of the date the Option is granted (110% in the case of
     an Incentive Stock Option granted to a Ten-Percent Stockholder).

          (b) Term. Options shall be for such term as the Committee shall
     determine, provided that no Option shall be exercisable after the
     expiration of ten years from the date it is granted (five years in the case
     of an Incentive Stock Option granted to a Ten-Percent Stockholder).

          (c) Vesting. Options shall be exercisable in such installments (which
     need not be equal) and at such times as the Committee may designate, as set
     forth in an Option Agreement. To the extent not exercised, installments
     shall accumulate and may be exercised, in whole or in part, at any time
     after becoming exercisable, but not later than the date the Option
     expires. The Committee may accelerate the exercisability of an Option at
     any time. Notwithstanding the foregoing, any Options that are not
     exercisable prior to a Change in Control shall become exercisable on the
     date of such Change in Control and shall remain exercisable for the
     remainder of their Term.

          (d) Exercise of Option After Termination of Employment.

          Subject to the terms of any written employment agreement and reflected
     in an Option Agreement, an Option granted under the Plan is exercisable by
     an Optionee only while he is an Employee, provided that any Options that
     are exercisable preceding an Optionee's Termination of Employment for any
     reason other than Cause, shall remain exercisable for the following period:

                                       4
<PAGE>
                  (i) If the Optionee dies while an Employee, or if his
Termination of Employment is due to Permanent Disability or Retirement, the
Optionee (or his Designated Beneficiary or personal representative, as
applicable) may exercise the Option no later than twelve (12) months after such
death or determination;

                  (ii) If the Optionee's Termination of Employment is for any
reason other than those set forth in (i) above and is not for Cause, the
Optionee may exercise the Option within three months after such termination;

                  (iii) If the Optionee dies during a period described in (i) or
(ii) above, his Designated Beneficiary may exercise such Option no later than
the expiration of such extended period; or

                  (iv) Notwithstanding (i) through (iii) above or anything in an
Option Agreement or the Plan to the contrary, at any time after the grant of an
Option, the Committee, in its sole and absolute discretion and subject to
whatever terms and conditions it selects, may provide that an Option may be
exercised after the relevant extended period set forth above, but in no event
later than the date that it would have expired under the Option Agreement.

         4.2 NONTRANSFERABILITY.

                  No Option granted hereunder shall be transferable by the
Optionee to whom granted otherwise than by will or the laws of descent and
distribution, and an Option may be exercised during the lifetime of such
Optionee only by the Optionee or his guardian or legal representative; provided,
however that an Optionee may designate a beneficiary to exercise his Option or
other rights under the Plan after his death and, in the discretion of the
Committee, Options may be transferable pursuant to a Qualified Domestic
Relations Order ("QDRO"), as determined by the Committee or its designee.

         4.3 METHOD OF EXERCISE.

                  An Option shall be exercised by delivery of a written notice
(in person or by first class mail to the Secretary of the Company at the
Company's principal executive office) which specifies the number of Shares to be
purchased and is accompanied by full payment therefor and otherwise in
accordance with the Option Agreement pursuant to which the Option was granted.
The purchase price for any Shares purchased pursuant to the exercise of an
Option shall be paid in full upon such exercise in cash or by check made payable
to the Company. If requested by the Committee, the Optionee shall deliver the
Option Agreement evidencing the Option to the Secretary of the Company who shall
endorse thereon a notation of such exercise and return such Option Agreement to
the Optionee. Not less than one hundred (100) Shares may be purchased at any
time upon the exercise of an Option unless the number of Shares so purchased
constitutes the total number of Shares then purchasable under the Option or the
Committee determines otherwise, in its sole discretion.

5. ADMINISTRATION.

         5.1 COMPOSITION OF COMPENSATION COMMITTEE.

                  The Plan shall be administered by the Committee, which shall
consist of at least three individuals appointed by and serving at the pleasure
of the Board, provided that each Committee member must qualify as an "outside

determines otherwise, in its sole discretion. All Committee members shall be
members of the Board. Appointment of Committee members shall be effective upon
acceptance of appointment Committee members may resign at any time by delivering

granted options, the number of Shares to be covered by each Option, the exercise
price therefor and the terms and conditions applicable to the exercise of the

Options or both. In the case of Incentive Stock Options, the terms and
conditions of such grants shall be subject to and shall comply with Section 422

Company and any Subsidiary (and, if applicable, any parent corporation, within
the meaning of Section 424(e) of the Code) that become exercisable by an
Optionee during any calendar year shall not exceed $100,000. To the extent that
the limitation set forth in the preceding sentence is exceeded for any reason
(including the acceleration of the time for exercise of an Option), the Options
with respect to such excess amount shall be treated as Nonqualified Stock
Options.

                  (b) It shall be the duty of the Committee to conduct the
general administration of the Plan in accordance with its terms and provisions.
The Committee shall have the power to interpret the Plan and to adopt such rules
for the administration, interpretation and application of the Plan as are
consistent therewith and to interpret, amend or revoke any such rules. All
actions taken and all interpretations and determinations made by the Committee
shall be binding upon all persons, including, but not limited to, the Company,
stockholders, all Subsidiaries, Employees, Directors, Optionees and Designated
Beneficiaries.

         5.3 COMMITTEE ACTIONS.

         5.6 NO LIABILITY.

                  No member of the Board or the Committee, or Director, officer
of the Company or other Employee shall be liable, responsible or accountable in
damages or otherwise for any determination made or other action taken or any
failure to act by such person with respect to the Plan so long as such person is
not determined to be guilty by a final adjudication of willful misconduct with
respect to such determination, action or failure to act.

         5.7 INDEMNIFICATION.

                  To the fullest extent permitted by law, each member of the
Board and the Committee and each Director, officer of the Company or Employee
shall be held harmless and be indemnified by the Company for any liability, loss
(including amounts paid in settlement), damages or expenses (including
reasonable attorneys' fees) suffered by virtue of any determinations, acts or
failures to act, or alleged acts or failures to act, in connection with the
administration of the Plan so long as such person is not determined by a final
adjudication to be guilty of willful misconduct with respect to such
determination, action or failure to act.

6. SHARES SUBJECT TO THE PLAN.

         6.1 SHARES SUBJECT TO THE PLAN.

                  The maximum number of Shares that may be issued upon the
exercise of Options granted under the Plan is 1,000,000.* The Company shall
reserve such number of Shares for the purposes of the Plan, out of its
authorized but unissued Shares or out of Shares held in the Company's treasury,
or partly out of each. In the event that an Option expires or is terminated
unexercised as to any Shares covered thereby, or is canceled or forfeited for
any reason under the Plan without the delivery of Shares, such Shares shall
thereafter be again available for award pursuant to the Plan.

*  On January 6, 2005, the Board amended the Plan such that (1) the number of
   Shares that may be issued under the Plan is limited to the number of Shares
   subject to outstanding Options on that date, and (2) with respect to options
   under the Plan that expire or are terminated unexercised as to any Shares
   covered thereby, or canceled or forfeited for any reason under the Plan
   without the delivery of Shares, the Shares covered thereby shall not be
   available again for awards pursuant to the Plan, in each case to further the
   intent that the ability of the Company to make new awards pursuant to the
   Plan was thereby terminated as of that date.

<PAGE>

         6.2 EFFECT OF CHANGES IN COMPANY'S SHARES.

                  In the event that the Committee determines that any stock
dividend, extraordinary cash dividend, recapitalization, reorganization, merger,
consolidation, split-up, spin-off, combination, exchange of shares, warrants or
rights offering to purchase Shares at a price substantially below fair market
value, or other similar corporate event affects the Shares such that an
adjustment is required in order to preserve the benefits or potential benefits
intended to be made available under the Plan, the Committee shall, in its sole
discretion, and in such manner as the Committee may deem equitable, adjust any
or all of (a) the number and kind of shares subject to outstanding Options, and
(b) the exercise price with respect to any outstanding Option and/or, if deemed
appropriate, make provision for a cash payment to an Optionee, provided,
however, that the number of Shares subject to any Option shall always be a whole
number.

7. MISCELLANEOUS.

         7.1 EFFECTIVE DATE; TERM OF PLAN.

                  The Plan has been approved by the Board and by the Company's
stockholders, and shall be effective as of the date of Board approval (the
"Effective Date"). The Plan shall continue in effect until ten years after the
date it was approved by the Company's stockholders.

         7.2 AMENDMENT, SUSPENSION OR TERMINATION OF THE PLAN.

                  The Plan may be wholly or partially amended or otherwise
modified, suspended or terminated at any time or from time to time by the Board.
Neither the amendment, suspension nor termination of the Plan shall, without the
consent of an Optionee, alter or impair any rights or obligations under any
option theretofore granted. No Options may be granted during any period of
suspension nor after termination of the Plan, and in no event may any Options be
granted under the Plan after June 16, 2013.

         7.3 AMENDMENT OF OPTION.

                  The Committee may amend, modify or terminate any outstanding
Option with the Optionee's consent at any time prior to payment or exercise in
any manner not inconsistent with the terms of the Plan, including without
limitation, (a) to change the date or dates as of which an Option becomes
exercisable or Shares become vested, or (b) to cancel and reissue an Option
under such different terms and conditions as it determines appropriate.

<PAGE>

         7.4 NO RIGHTS AS STOCKHOLDER.

                  No holder of an Option shall be deemed to be or to have the
rights and privileges of an owner of Shares unless and until certificates
representing such Shares have been issued to such holder. As a condition to any
exercise of the Option by the Optionee, the Optionee shall be required to be a
party to, or to contemporaneously with such exercise become a party to, the
Stockholders Agreement

         7.5 EFFECT OF PLAN UPON OTHER COMPENSATION AND INCENTIVE PLANS.

                  The adoption of the Plan shall not affect any other
compensation or incentive plans in effect for the Company or any Subsidiary.
Nothing in the Plan shall be construed to limit the right of the Company or any
Subsidiary to establish any other forms of incentives or compensation for
Employees.

         7.6 REGULATIONS AND OTHER APPROVALS.

                  (a) The obligation of the Company to sell or deliver Shares

necessary or appropriate by the Committee.

                  (b) The Committee may make such changes as may be necessary or
appropriate to comply with the rules and regulations of any government authority
or to obtain the tax benefits under the applicable provisions of the Code and
regulations promulgated thereunder for Employees granted Incentive Stock
Options.

                  (c) Each Option is subject to the requirement that, if at any
time the Committee determines, in its sole discretion, that the listing,
registration or qualification of Shares issuable pursuant to the Plan is
required by any securities exchange or under any state or federal law, or the
consent or approval of any governmental regulatory body is necessary or
desirable as a condition of, or in connection with, the grant of an Option or
the issuance of Shares, no Options shall be granted or Shares issued, in whole
or in part, unless listing, registration, qualification, consent or approval has
been effected or obtained free of any conditions as acceptable to the Committee.

                  (d) In the event that the disposition of Shares acquired
pursuant to the Plan is not covered by a then current registration statement
under the Securities Act, and is not otherwise exempt from such registration,
such Shares shall be restricted against transfer to the extent required by the
Securities Act or regulations thereunder, and the Committee may require any
individual receiving Shares pursuant to the Plan, as a condition precedent to
receipt of such Shares, to represent to the Company in writing that the Shares
acquired by such individual are acquired for investment only and not with a view
to distribution. The certificate for any Shares acquired pursuant to the Plan
shall include any legend that the Committee deems appropriate to reflect any
restrictions on transfer.

holding of shares received upon exercise of an Option, to the extent required by
law, no later than the date as to which an amount first becomes includible in
the gross income of an Optionee for federal income tax purposes with respect to
any award granted under the Plan, the Optionee shall pay to the Company, or make
arrangements satisfactory to the Company regarding the minimum statutory payment
of, any federal, state, or local taxes of any kind required by law or the
Company to be withheld with respect to such amount. The obligations of the
Company under the Plan shall be conditional on such payment or arrangements and
the Company and its Subsidiaries shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
Optionee.

         7.9 NO RIGHT TO CONTINUED EMPLOYMENT.

terminate or discharge any Employee at any time for any reason whatsoever, with

                  (b) Adjustments in Option. In the event that the outstanding
Shares subject to the Option are changed into or exchanged for a different
number or kind of shares or securities of the Company, or of another
corporation, by reason of reorganization, merger or other subdivision,
consolidation, recapitalization, reclassification, stock split, issuance of
warrants, stock dividend or combination of shares or similar event, the
Committee shall make an appropriate and equitable adjustment in the Option so
that the Optionee's proportionate interest shall be maintained as before the
occurrence of such event, provided that any such adjustment shall be consistent
with the provisions of the Optionee's employment agreement, if applicable.

                  (c) Form of Option. Options are to be Incentive Stock Options.

                  (d) Term. The Option shall expire on the      anniversary
(     anniversary in the case of an Incentive Stock Option granted to a
ten-percent stockholder) of the Grant Date, unless terminated earlier by the
Committee.

                  (e) Vesting. Subject to the provisions of Section 4.1(c) of
the Plan, the Options are immediately vested on the Grant Date.

                  (f) Exercise. The Optionee may exercise an Option in whole or
in part at any time by delivering written notice of such exercise to the
Secretary of the Company of the number of Shares as to which the Option is being
exercised, and enclosing payment for the Shares with respect to which the Option
is being exercised. Such payment shall be in cash or by check, made payable to
the Company. Partial exercise shall be for whole Shares only and shall not be
for less than one hundred (100) Shares unless the number of Shares purchased
constitutes the total

                                       11
<PAGE>

number of Shares then remaining subject to the Option or the Committee permits
such smaller exercise in its sole discretion.

                  (g) Exercise Following Termination of Employment. In the event
the Optionee's Termination of Employment is for Cause, the Option, whether
exercisable or nonexercisable, at such time, shall be deemed to have terminated
as of the day preceding such Termination of Employment. If such Termination of
Employment is for any reason other than for Cause, any outstanding portion of
the Option that has become exercisable shall be exercisable for the following
periods:

                           (i)      If the Optionee dies while an Employee, or
                                    if his Termination of Employment is due to
                                    Permanent Disability or Retirement, the
                                    Optionee (or his Designated Beneficiary or
                                    personal representative, as applicable) may
                                    exercise the Option no later than twelve
                                    (12) months after such death or
                                    determination;

                           (ii)     If the Optionee's Termination of Employment
                                    is for any reason other than those set forth
                                    in (i) above and is not for Cause, the
                                    Optionee may exercise the Option within
                                    three months after such termination;

                           (iii)    If the Optionee dies during a period
                                    described in (i) or (ii) above, his
                                    Designated Beneficiary may exercise such
                                    Option no later than the expiration of such
                                    extended period; or

                           (iv)     Notwithstanding (i) through (iii) above or
                                    anything in an Option Agreement or the Plan
                                    to the contrary, at any time after the grant
                                    of an Option, the Committee, in its sole and
                                    absolute discretion and subject to whatever
                                    terms and conditions it selects, may provide
                                    that an Option may be exercised after the
                                    relevant extended period set forth above,
                                    but in no event later than the date that it
                                    would have expired under the Option
                                    Agreement.

                  (h) Nontransferability. The Option shall not be transferable
other than by will or the laws of descent and distribution, and no transfer so
effected shall be effective to bind the Company unless the Company has been
furnished with written notice thereof and a copy of the will and/or such other
evidence as the Committee may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions of the Option, provided, however, that, in the discretion of the
Committee, Options may be transferred pursuant to a Qualified Domestic Relations
Order (within the meaning of the Code).

                  (i) Conditions to Issuance of Stock Certificates.

                           (i)      The Shares deliverable upon the exercise of
                                    the Option, or any portion thereof, may be
                                    either previously authorized but unissued
                                    Shares or issued Shares which have been
                                    reacquired by the Company. Such Shares shall
                                    be fully

                                    certificates evidencing the Shares shall
                                    bear such legends restricting
                                    transferability as the Committee deems
                                    necessary or advisable.

                           (ii)     The Company shall not be required to issue
                                    or deliver any certificate or certificates
                                    for Shares deliverable upon any exercise of
                                    the Option prior to fulfillment of all of
                                    the following conditions:

                                    1)       The completion of any registration
                                             or other qualification of such
                                             Shares under any federal law or
                                             under rulings or regulations of the
                                             Securities and Exchange Commission
                                             or of any other governmental
                                             regulatory body, or the obtaining
                                             of approval or other clearance from
                                             any state or federal governmental
                                             agency which the Committee shall,
                                             in its sole discretion, deem
                                             necessary or advisable.

                                    2)       If, in its sole discretion, the
                                             Committee deems it necessary or
                                             advisable, the execution by the
                                             Optionee of a written
                                             representation and agreement, in a
                                             form satisfactory to the Committee,
                                             in which the Optionee represents
                                             that the Shares acquired by him
                                             upon exercise are being acquired
                                             for investment and not with a view
                                             to distribution thereof.

                  (j) Rights as Stockholder. The Optionee shall not be, nor have
any of the rights or privileges of, a stockholder of the Company in respect of
any Shares purchasable upon the exercise of the Option unless and until
certificates representing such Shares have been issued by the Company. As a
condition to any exercise of the Option by the Optionee, the Optionee shall be
required to be a party to, or to contemporaneously with such exercise become a
party to, the Stockholders Agreement.

3. MISCELLANEOUS.

an amount first becomes includible in the gross income of the Optionee for
federal income tax purposes with respect to the grant of the Option under this
Agreement, the Optionee shall pay to the Company, or the Optionee (or his
Designated Beneficiary) shall make arrangements satisfactory to the Company
regarding the minimum statutory payment of, any federal, state, or local taxes
of any kind required by law or the Company to be withheld with respect to such
amount. The obligations of the Company under this Agreement shall be conditioned

arrangements, and the Company shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
Optionee.

the employ of the Company or shall interfere with or restrict in any way the
rights of the Company, which are hereby expressly reserved, to discharge the
Optionee at any time for any reason whatsoever, with or without cause.

                  (d) Entire Agreement; Amendment. This Agreement, and the Plan,

                                     PURPOSE

      The purpose of this Sybari Software, Inc. 2005 Stock Incentive Plan (the

Affiliates for the benefit of its stockholders by enabling the Company to offer
stock-based incentives and other equity interests in the Company to selected
employees of the Company and its Affiliates, Non-Employee Directors and
Consultants, thereby creating a means to raise the level of stock ownership by
such individuals in order to attract, retain and reward such individuals and
strengthen the mutuality of interests between such individuals and the Company's
stockholders.

                                   Article 2.
                                   DEFINITIONS

      For purposes of the Plan, the following terms shall have the following

4.2(d).

(i) any Subsidiary; (ii) any Parent; (iii) any corporation, trade or business
(including, without limitation, a partnership or limited liability company) that

assets or an equivalent ownership interest or voting interest) by the Company;
or (iv) any other entity, approved by the Committee as an Affiliate under the
Plan, in which the Company directly or indirectly has a material equity
interest.

      2.3 "AWARD" shall mean any award under the Plan of any Stock Option,

similar agreement in effect between the Company or an Affiliate and the
Participant at the time of the relevant grant or Award, or where there is an
employment agreement, consulting agreement, change in control agreement or
similar agreement in effect at the time of the relevant grant or Award but such
agreement does not define "cause" (or words of like import), termination due to
a Participant's dishonesty, fraud, insubordination, willful misconduct, refusal
to perform services (for any reason other than illness or incapacity) or
materially unsatisfactory performance of his or her duties for the Company or an
Affiliate or (ii) in the case where there is an employment agreement, consulting
agreement, change in control agreement or similar agreement in effect between
the Company or an Affiliate and the Participant at the time of the relevant

like import) and a "cause" termination would be permitted under such agreement
at that time, termination that is or would be deemed to be for "cause" (or words
of like import) as defined under such agreement; provided, that with regard to
any agreement that conditions "cause" on occurrence of a change in control, such
definition of "cause" shall not apply until a change in control actually takes
place and then only with regard to a termination thereafter. For a Non-Employee
Director, "Cause" shall mean an act or failure to act that constitutes cause for

applicable registration, stock exchange, quotation system, listing or similar
rules or regulations or applicable accounting rules, a "non-employee director,"
"outside director" or "independent director" (or term of similar import);
provided, however, that if and to the extent that no Committee exists that has
the authority to administer the Plan, the functions of the Committee shall be
exercised by the Board and all references herein to the Committee shall be
deemed to be references to the Board; and (b) with respect to the application of
the Plan to Non-Employee Directors, the Board. If for any reason the appointed
Committee does not meet the requirements of Rule 16b-3, such noncompliance with
the requirements of Rule 16b-3 shall not affect the validity of the Awards,
grants, interpretations or other actions of the Committee.

otherwise supervise the administration of the Plan. The Committee may correct
any defect, supply any omission or reconcile any inconsistency in the Plan or in
any agreement or grant letter relating thereto in the manner and to the extent
it shall deem necessary to carry the Plan into effect but only to the extent any
such action would be permitted under the applicable provisions of Rule 16b-3.
The Committee may adopt special guidelines and provisions for persons who are
residing in, or subject to the taxes of, countries other than the United States
to comply with applicable tax and securities laws and may impose any limitations
and restrictions that they deem necessary to comply with the applicable tax and

      of the Company or member or former member of the Committee or of the Board
      shall be liable for any action or determination made in good faith with
      respect to the Plan or any Award granted under it. To the maximum extent
      permitted by applicable law and the Certificate of Incorporation and
      By-Laws of the Company and to the extent not covered by insurance, each
      officer, employee of the Company and member or former member of the
      Committee or of the Board shall be indemnified and held harmless by the

      in settlement of a claim with the approval of the Company), and advanced
      amounts necessary to pay the foregoing at the earliest time and to the
      fullest extent permitted, arising out of any act or omission to act in
      connection with the Plan, except to the extent arising out of such
      officer's, employee's, member's or former member's own fraud or bad faith;
      provided, however, that the payment of expenses in advance of the
      settlement or final disposition of a suit, action or proceeding shall be
      made only upon delivery to the Company of an undertaking by or on behalf
      of such person to repay all amounts so advanced if it is ultimately
      determined that such person is not entitled to be indemnified hereunder.
      The indemnification described in this Section shall be in addition to any
      rights of indemnification the person may have as a

<PAGE>

      director, officer or employee or under the Certificate of Incorporation of
      the Company or the By-Laws of the Company. Expenses incurred by the
      Committee or the Board of Directors in the engagement of any such counsel,
      consultant or agent shall be paid by the Company. Such indemnification
      shall be in addition to any rights of indemnification the officers,
      employees, directors or members or former officers, directors or members
      may have under applicable law or under the Certificate of Incorporation or
      By-Laws of the Company or Affiliates. Notwithstanding anything else
      herein, this indemnification will not apply to the actions or
      determinations made by an individual with regard to Awards granted to him
      or her under the Plan.

                                   Article 4.
                           SHARE AND OTHER LIMITATIONS

      4.1 Shares.

            (a) General Limitation. The aggregate number of shares of Common
      Stock that may be issued or used for reference purposes under the Plan or
      with respect to which all Awards may be granted shall not exceed 1,500,000
      shares (subject to any increase or decrease pursuant to Section 4.2);
      provided, however, that notwithstanding the foregoing, no more than
      1,125,000 shares (subject to any increase or decrease pursuant to Section
      4.2) shall be subject to Awards of Restricted Stock. If any Option or
      Stock Appreciation Right granted under the Plan expires, terminates or is
      canceled for any reason without having been exercised in full, the number
      of shares of Common Stock underlying any unexercised Stock Appreciation
      Right or Option shall again be available for the purposes of Awards under
      the Plan. If any shares of Restricted Stock awarded under the Plan to a
      Participant are forfeited for any reason, the number of forfeited shares
      of Restricted Stock shall again be available for the purposes of Awards
      under the Plan. If a Tandem Stock Appreciation Right or a Limited Stock
      Appreciation Right is granted in tandem with an Option, such grant shall
      only apply once against the maximum number of shares of Common Stock that
      may be issued under the Plan. In addition, to the extent consistent with
      applicable law and, in the case of Incentive Stock Options, with the
      treatment of an Incentive Stock Option as such, in determining the number
      of shares of Common Stock available for Awards, if Common Stock has been
      delivered or exchanged by a Participant as full or partial payment to the
      Company for payment of the exercise price or payment of withholding taxes,
      or if the number shares of Common Stock otherwise deliverable has been
      reduced for payment of the exercise price or payment of withholding taxes,
      the number of shares of Common Stock so exchanged or reduced shall again
      be available for purposes of Awards.

            (b) Individual Participant Limitations.

                  (i) The maximum number of shares of Common Stock subject to
            any Stock Appreciation Right, Non-Qualified Option, Incentive Stock
            Option, award of Restricted Stock or Other Stock-Based Award that
            may be granted under the Plan during any fiscal year of the Company
            to a Participant shall be 750,000 shares (subject to any increase or
            decrease pursuant to Section 4.2). If a Tandem Stock Appreciation
            Right or Limited Stock Appreciation Right is granted in

<PAGE>

            tandem with an Option it shall apply against the Participant's
            individual share limitations for both Stock Appreciation Rights and
            Options.

                  (ii) To the extent that shares of Common Stock for which
            Awards are permitted to be granted to a Participant pursuant to
            Section 4.1(b) during a fiscal year of the Company are not covered
            by an Award in the Company's fiscal year, such shares of Common
            Stock shall not be available for grant or issuance to the
            Participant in any subsequent fiscal year during the term of the
            Plan.

      4.2 Changes.

            (a) The existence of the Plan and the Awards granted hereunder shall
      not affect in any way the right or power of the Board or the stockholders
      of the Company to make or authorize any adjustment, recapitalization,
      reorganization or other change in the Company's capital structure or its
      business, any merger or consolidation of the Company or its Affiliates,
      any issue of bonds, debentures, preferred or prior preference stock ahead
      of or affecting Common Stock, the dissolution or liquidation of the
      Company or its Affiliates, any sale or transfer of all or part of its
      assets or business or any other corporate act or proceeding.

            (b) Subject to Section 4.2(d), in the event of any such change in
      the capital structure or business of the Company by reason of any stock
      dividend or distribution, stock split or reverse stock split,
      recapitalization, reorganization, merger, consolidation, split-up,
      combination or exchange of shares, distribution with respect to its
      outstanding Common Stock or capital stock other than Common Stock,
      reclassification of its capital stock, conversion of the Company's
      preferred stock, issuance of warrants or options to purchase any Common
      Stock or securities convertible into Common Stock, any sale or Transfer of
      all or part of the Company's assets or business, any complete or partial
      liquidation, or any similar change affecting the Company's capital
      structure or business, then the aggregate number and kind of shares that
      thereafter may be issued under the Plan, the number and kind of shares or
      other property (including cash) to be issued upon exercise of an
      outstanding Option or other Awards (collectively, "EXERCISABLE AWARDS")
      granted under the Plan and the purchase price thereof shall be
      appropriately adjusted consistent with such change in such manner as the
      Committee may deem equitable to prevent substantial dilution or
      enlargement of the rights granted to, or available for, Participants under
      the Plan, and any such adjustment determined by the Committee in good
      faith shall be binding and conclusive on the Company and all Company and
      Affiliate employees, directors, consultants (whether current or former)
      and their respective heirs, executors, administrators, successors and
      assigns.

            (c) Fractional shares of Common Stock resulting from any adjustment
      in Exercisable Awards pursuant to Section 4.2(a) or (b) shall be
      aggregated until, and eliminated at, the time of exercise by rounding down
      for fractions less than one-half (1/2) and rounding up for fractions equal
      to or greater than one-half (1/2). No cash settlements shall be made with
      respect to fractional shares eliminated by rounding. Notice of any
      adjustment shall be given by the Committee to each Participant whose
      Exercisable Award

<PAGE>

      has been adjusted and such adjustment (whether or not such notice is
      given) shall be effective and binding for all purposes of the Plan.

            (d) In the event of a merger or consolidation in which the Company
      is not the surviving entity or in the event of any transaction that
      results in the acquisition of substantially all of the Company's
      outstanding Common Stock by a single person or entity or by a group of
      persons and/or entities acting in concert, or in the event of the sale or
      transfer of all or substantially all of the Company's assets (all of the
      foregoing being referred to as "ACQUISITION EVENTS"), then the Committee
      may, in its sole discretion, terminate all outstanding Options, Stock
      Appreciation Rights and Other Stock-Based Awards of Participants,
      effective as of the date of the Acquisition Event, by delivering notice of
      termination to each such Participant at least twenty (20) days prior to
      the date of consummation of the Acquisition Event; provided, that during
      the period from the date on which such notice of termination is delivered
      to the consummation of the Acquisition Event, each such Participant shall
      have the right to exercise in full all of his or her Exercisable Awards
      that are then outstanding (unless otherwise provided in the agreement or
      grant letter associated with such Exercisable Award) but contingent on
      occurrence of the Acquisition Event, and, provided that, if the
      Acquisition Event does not take place within a specified period after
      giving such notice for any reason whatsoever, the notice and exercise
      shall be null and void. If an Acquisition Event occurs, to the extent the
      Committee has not terminated any outstanding Exercisable Awards pursuant
      to this Section 4.2(d), then the provisions of Section 4.2(b) shall apply.

      4.3 Minimum Purchase Price. Notwithstanding any provision of the Plan to
the contrary, if authorized but previously unissued shares of Common Stock are
issued under the Plan, such shares shall not be issued for a consideration that
is less than as permitted under applicable law.

Other Stock-Based Awards under the Plan. Eligibility under the Plan shall be
determined by the Committee in its sole and absolute discretion.

                                   Article 6.
                                  STOCK OPTIONS

      6.1 Options. Each Stock Option granted hereunder shall be one of two
types: (i) an Incentive Stock Option intended to satisfy the requirements of
Section 422 of the Code or (ii) a Non-Qualified Stock Option.

      6.2 Grants. The Committee shall have the authority to grant (x) to any
employee of the Company or an Affiliate described in Section 2.2(i) or (ii), one
or more Incentive Stock Options, Non-Qualified Stock Options or both types of
Stock Options (in each case, with or without Stock Appreciation Rights) and (y)
to any Eligible Employee, Non-Employee Director

<PAGE>

or Consultant, one or more Non-Qualified Stock Options (with or without Stock
Appreciation Rights). To the extent that any Stock Option does not qualify as an
Incentive Stock Option (whether because of its provisions or the time or manner
of its exercise or otherwise), such Stock Option or the portion thereof that
does not qualify shall constitute a separate Non-Qualified Stock Option.
Notwithstanding any other provision of the Plan to the contrary or any provision
in an agreement or grant letter evidencing the grant of an Option to the
contrary, any Option granted to a Participant who is not an employee of the
Company or an Affiliate described in Section 2.2(i) or (ii) shall be a
Non-Qualified Stock Option.

      6.3 Terms of Options. Options granted under Article 6 of the Plan shall be
subject to Article 11 and the following terms and conditions, and shall be in
such form and contain such additional terms and conditions, not inconsistent
with the terms of the Plan, as the Committee shall deem desirable:

            (a) Option Price. The option price per share of Common Stock
      purchasable under an Incentive Stock Option or a Non-Qualified Stock
      Option shall be determined by the Committee at the time of grant but shall
      not be less than 100% of the Fair Market Value of the share of Common
      Stock at the time of grant; provided, however, if an Incentive Stock
      Option is granted to a Ten Percent Stockholder, the purchase price shall
      not be less than 110% of the Fair Market Value of the share of Common
      Stock at the time of grant.

            (b) Option Term. The term of each Stock Option shall be fixed by the
      Committee, but no Stock Option shall be exercisable more than ten (10)
      years after the date the Option is granted; provided, however, that the
      term of an Incentive Stock Option granted to a Ten Percent Stockholder may
      not exceed five (5) years.

            (c) Exercisability. Stock Options shall be exercisable at such time
      or times and subject to such terms and conditions as shall be determined
      by the Committee at grant. If the Committee provides, in its discretion,
      that any Stock Option is exercisable subject to certain limitations
      (including, without limitation, that it is exercisable only in
      installments or within certain time periods), the Committee may waive such
      limitations on the exercisability at any time at or after grant in whole
      or in part (including, without limitation, that the Committee may waive
      the installment exercise provisions or accelerate the time at which
      Options may be exercised), based on such factors, if any, as the Committee
      shall determine, in its sole discretion. Unless otherwise determined by
      the Committee at grant, (i) in the event the Participant engages in a
      Detrimental Activity prior to any exercise of the Stock Option, all Stock
      Options held by the Participant shall thereupon terminate and expire, (ii)
      as a condition of the exercise of a Stock Option, the Participant shall be
      required to certify (or shall be deemed to have certified) at the time of
      exercise in a manner acceptable to the Company that the Participant is in
      compliance with the terms and conditions of the Plan and that the
      Participant has not engaged in, and does not intend to engage in, any
      Detrimental Activity, and (iii) in the event the Participant engages in a
      Detrimental Activity during the one-year period commencing on the date the
      Stock Option is exercised, the Company shall be entitled to recover from
      the Participant at any time within one year after such exercise or
      vesting, and the Participant shall pay

<PAGE>

      over to the Company, an amount equal to any gain realized as a result of
      the exercise (whether at the time of exercise or thereafter). The
      foregoing provisions described in subsections (i), (ii) and (iii) shall
      cease to apply upon a Change in Control.

            (d) Method of Exercise. Subject to whatever installment exercise and
      waiting period provisions apply under subsection (c) above, Stock Options
      may be exercised in whole or in part at any time during the Option term,
      by giving written notice of exercise to the Company specifying the number
      of shares to be purchased. Such notice shall be accompanied by payment in
      full of the purchase price as follows: (i) in cash or by check, bank draft
      or money order payable to the order of Company, (ii) solely to the extent
      authorized by the Committee at the time of exercise and consistent with
      applicable law, if the Common Stock is traded on a national securities
      exchange, the Nasdaq Stock Market or quoted on a national quotation system
      sponsored by the National Association of Securities Dealers, through the
      delivery of irrevocable instructions to a broker to deliver promptly to
      the Company an amount equal to the purchase price, (iii) by payment in
      full or part in the form of Common Stock owned by the Participant for a
      period of at least 6 months or such other period as may be required to
      avoid a charge to earnings (and for which the Participant has good title
      free and clear of any liens and encumbrances) based on the Fair Market
      Value of the Common Stock on the payment date as determined by the
      Committee or the Board or (iv) on such other terms and conditions as may
      be acceptable to the Committee or the Board, as applicable. No shares of
      Common Stock shall be issued until payment therefor, as provided herein,
      has been made or provided for.

            (e) Incentive Stock Option Limitations. To the extent that the
      aggregate Fair Market Value (determined as of the time of grant) of the
      Common Stock with respect to which Incentive Stock Options are exercisable
      for the first time by an Eligible Employee during any calendar year under
      the Plan and/or any other stock option plan of the Company or any
      Subsidiary or Parent exceeds $100,000, such Options shall be treated as
      Options that are not Incentive Stock Options. In addition, if an Eligible
      Employee does not remain employed by the Company, any Subsidiary or Parent
      at all times from the time the Option is granted until three (3) months
      prior to the date of exercise (or such other period as required by
      applicable law), such Option shall be treated as an Option that is not an
      Incentive Stock Option. Should the foregoing provision not be necessary in
      order for the Stock Options to qualify as Incentive Stock Options or
      should any additional provisions be required, the Committee may amend the
      Plan accordingly, without the necessity of obtaining the approval of the
      stockholders of the Company.

            (f) Form of Options. Subject to the terms and conditions and within
      the limitations of the Plan, an Option shall be evidenced by such form of
      agreement or grant letter as is approved by the Committee.

            (g) Form of Settlement. In its sole discretion, the Committee may
      provide, at the time of grant, that the shares to be issued upon the
      exercise of a Stock Option shall be in the form of Restricted Stock, or
      may, in the Option agreement or grant letter, reserve a right to so
      provide after the time of grant.

<PAGE>

            (h) Deferred Delivery of Common Shares. The Committee may in its
      discretion permit Participants to defer delivery of Common Stock acquired
      pursuant to a Participant's exercise of an Option in accordance with the
      terms and conditions established by the Committee.

            (i) Early Exercise. The Committee may provide that a Stock Option
      include a provision whereby the Participant may elect at any time before
      the Participant's Termination to exercise the Stock Option as to any part
      or all of the shares of Common Stock subject to the Stock Option prior to
      the full vesting of the Stock Option and such shares shall be subject to
      the provisions of Article 7 and treated as Restricted Stock. Any unvested
      shares of Common Stock so purchased may be subject to a repurchase option
      in favor of the Company or to any other restriction the Committee
      determines to be appropriate.

            (j) Other Terms and Conditions. Options may contain such other
      provisions, which shall not be inconsistent with any of the foregoing
      terms of the Plan, as the Committee shall deem appropriate, including,
      without limitation, permitting "reloads." With regard to such "reloads,"
      the Committee shall have the authority (but not an obligation) to include
      within any Option agreement or grant letter a provision entitling the
      Participant to a further Option (a "RELOAD OPTION") if the Participant
      exercises the Option evidenced by the Option agreement or grant letter, in
      whole or in part, by surrendering other shares of the Company held by the
      Participant for at least six (6) months prior to such date of surrender in
      accordance with the Plan and the terms and conditions of the Option
      agreement or grant letter. Any Reload Option shall not be an Incentive
      Stock Option, shall be for a number of shares equal to the number of
      surrendered shares, the exercise price thereof shall be equal to the Fair
      Market Value of the Common Stock on the date of exercise of such original
      Option, shall become exercisable if the purchased shares are held for a
      minimum period of time established by the Committee, and shall be subject
      to such other terms and conditions as the Committee may determine.

                                   Article 7.
                             RESTRICTED STOCK AWARDS

      7.1 Awards of Restricted Stock. Shares of Restricted Stock may be issued
to Eligible Employees, Non-Employee Directors or Consultants either alone or in
addition to other Awards granted under the Plan. The Committee shall determine
the eligible persons to whom, and the time or times at which, grants of
Restricted Stock will be made, the number of shares to be awarded, the price (if
any) to be paid by the recipient (subject to Section 7.2), the time or times
within which such Awards may be subject to forfeiture, the vesting schedule and
rights to acceleration thereof, and all other terms and conditions of the
Awards. In addition, unless otherwise determined by the Committee at grant, in
the event the Participant engages in a Detrimental Activity prior to, or during
the one-year period after, any vesting of Restricted Stock, the Committee may
direct that all unvested Restricted Stock shall be immediately forfeited to the
Company and that the Participant shall pay over to the Company an amount equal
to the Fair Market Value at the time of vesting of any Restricted Stock that had
vested in the period referred to above. The foregoing provision shall cease to
apply upon a Change in Control.

<PAGE>

      7.2 Awards and Certificates. An Eligible Employee, Non-Employee Director
or Consultant selected to receive Restricted Stock shall not have any rights
with respect to such Award, unless and until such Participant has delivered a
fully executed copy of the Restricted Stock Award agreement or grant letter
evidencing the Award to the Company and has otherwise complied with the
applicable terms and conditions of such Award. Further, such Award shall be
subject to the following conditions:

            (a) Purchase Price. The purchase price of Restricted Stock shall be
      fixed by the Committee. Subject to Section 4.3, the purchase price for
      shares of Restricted Stock may be the minimum permitted by applicable law.

            (b) Acceptance. Awards of Restricted Stock must be accepted within a
      period of ninety (90) days (or such shorter period as the Committee may
      specify at grant) after the Award date, by executing a Restricted Stock
      Award agreement or grant letter and by paying whatever price (if any) the
      Committee has designated thereunder.

            (c) Legend. Each Participant receiving a Restricted Stock Award
      shall be issued a stock certificate in respect of such shares of
      Restricted Stock, unless the Committee elects to use another system, such
      as book entries by the transfer agent, as evidencing ownership of a
      Restricted Stock Award. Such certificate shall be registered in the name
      of such Participant, and shall bear an appropriate legend referring to the
      terms, conditions, and restrictions applicable to such Award,
      substantially in the following form:

            "The anticipation, alienation, attachment, sale, transfer,
            assignment, pledge, encumbrance or charge of the shares of stock
            represented hereby are subject to the terms and conditions
            (including forfeiture) of the Sybari Software, Inc. (the "Company")
            2005 Stock Incentive Plan, and an associated agreement or a grant
            letter dated ________. Copies of such Plan and agreement or grant
            letter are on file at the principal office of the Company."

            (d) Custody. The Committee may require that any stock certificates
      evidencing such shares be held in custody by the Company until the
      restrictions thereon shall have lapsed, and that, as a condition of any
      Restricted Stock Award, the Participant shall have delivered a duly signed
      stock power, endorsed in blank, relating to the Common Stock covered by
      such Award.

      7.3 Restrictions and Conditions on Restricted Stock Awards. The shares of
Restricted Stock awarded pursuant to the Plan shall be subject to Article 11 and
the following restrictions and conditions:

            (a) Restriction Period; Vesting and Acceleration of Vesting. The
      Participant shall not be permitted to Transfer shares of Restricted Stock
      awarded under the Plan during a period set by the Committee (the
      "RESTRICTION PERIOD") commencing with the date of such Award, as set forth
      in the Restricted Stock Award agreement or grant letter, and such
      agreement or grant letter shall set forth a vesting schedule and any
      events that

<PAGE>

      would accelerate vesting of the shares of Restricted Stock. Within these
      limits, based on service and/or such other factors or criteria as the
      Committee may determine in its sole discretion, the Committee may provide
      for the lapse of such restrictions in installments in whole or in part, or
      may accelerate the vesting of all or any part of any Restricted Stock
      Award and/or waive the deferral limitations for all or any part of any
      Restricted Stock Award.

            (b) Rights as Stockholder. Except as provided in this subsection (b)
      and subsection (a) above and as otherwise determined by the Committee, the
      Participant shall have, with respect to the shares of Restricted Stock,
      all of the rights of a holder of shares of Common Stock of the Company,
      including, without limitation, the right to receive any dividends, the
      right to vote such shares and, subject to and conditioned upon the full
      vesting of shares of Restricted Stock, the right to tender such shares.
      Notwithstanding the foregoing, the payment of dividends shall be deferred
      until, and conditioned upon, the expiration of the applicable Restriction
      Period, unless the Committee, in its sole discretion, specifies otherwise
      at the time of the Award.

            (c) Lapse of Restrictions. If and when the Restriction Period
      expires without a prior forfeiture of the Restricted Stock subject to such
      Restriction Period, the certificates for such shares shall be delivered to
      the Participant. All legends shall be removed from said certificates at
      the time of delivery to the Participant except as otherwise required by
      applicable law.

                                   Article 8.
                            STOCK APPRECIATION RIGHTS

      8.1 Tandem Stock Appreciation Rights. Stock Appreciation Rights may be
granted in conjunction with all or part of any Stock Option (a "REFERENCE STOCK
OPTION") granted under the Plan ("TANDEM STOCK APPRECIATION RIGHTS"). In the
case of a Non-Qualified Stock Option, such rights may be granted either at or
after the time of the grant of such Reference Stock Option. In the case of an
Incentive Stock Option, such rights may be granted only at the time of the grant
of such Reference Stock Option.

      8.2 Terms and Conditions of Tandem Stock Appreciation Rights. Tandem Stock
Appreciation Rights granted hereunder shall be subject to such terms and
conditions, not inconsistent with the provisions of the Plan, as shall be
determined from time to time by the Committee, including Article 11 and the
following:

            (a) Term. A Tandem Stock Appreciation Right or applicable portion
      thereof granted with respect to a Reference Stock Option shall terminate
      and no longer be exercisable upon the termination or exercise of the
      Reference Stock Option, except that, unless otherwise determined by the
      Committee, in its sole discretion, at the time of grant, a Tandem Stock
      Appreciation Right granted with respect to less than the full number of
      shares covered by the Reference Stock Option shall not be reduced until,
      and then only to the extent that, the exercise or termination of the
      Reference Stock Option causes the number of shares covered by the Tandem
      Stock Appreciation Right to exceed the number of shares remaining
      available and unexercised under the Reference Stock Option.

<PAGE>

            (b) Exercisability. Tandem Stock Appreciation Rights shall be
      exercisable only at such time or times and to the extent that the
      Reference Stock Options to which they relate shall be exercisable in
      accordance with the provisions of Article 6 and Article 8.

            (c) Method of Exercise. A Tandem Stock Appreciation Right may be
      exercised by a Participant by surrendering the applicable portion of the
      Reference Stock Option. Upon such exercise and surrender, the Participant
      shall be entitled to receive an amount determined in the manner prescribed
      in this Section 8.2. Stock Options that have been so surrendered, in whole
      or in part, shall no longer be exercisable to the extent the related
      Tandem Stock Appreciation Rights have been exercised.

            (d) Payment. Upon the exercise of a Tandem Stock Appreciation Right
      a Participant shall be entitled to receive up to, but no more than, an
      amount in cash and/or Common Stock (as chosen by the Committee in its sole
      discretion) equal in value to the excess of the Fair Market Value of one
      share of Common Stock over the Option price per share specified in the
      Reference Stock Option multiplied by the number of shares in respect of
      which the Tandem Stock Appreciation Right shall have been exercised, with
      the Committee having the right to determine the form of payment.

            (e) Deemed Exercise of Reference Stock Option. Upon the exercise of
      a Tandem Stock Appreciation Right, the Reference Stock Option or part
      thereof to which such Stock Appreciation Right is related shall be deemed
      to have been exercised for the purpose of the limitation set forth in
      Article 4 of the Plan on the number of shares of Common Stock to be issued
      under the Plan.

      8.3 Non-Tandem Stock Appreciation Rights. Non-Tandem Stock Appreciation
Rights may also be granted without reference to any Stock Options granted under
the Plan.

      8.4 Terms and Conditions of Non-Tandem Stock Appreciation Rights.
Non-Tandem Stock Appreciation Rights granted hereunder shall be subject to such
terms and conditions, not inconsistent with the provisions of the Plan, as shall
be determined from time to time by the Committee, including Article 11 and the
following:

            (a) Term. The term of each Non-Tandem Stock Appreciation Right shall
      be fixed by the Committee, but shall not be greater than ten (10) years
      after the date the right is granted.

            (b) Exercisability. Non-Tandem Stock Appreciation Rights shall be
      exercisable at such time or times and subject to such terms and conditions
      as shall be determined by the Committee at grant. If the Committee
      provides, in its discretion, that any such right is exercisable subject to
      certain limitations (including, without limitation, that it is exercisable
      only in installments or within certain time periods), the Committee may
      waive such limitation on the exercisability at any time at or after grant
      in whole or in part (including, without limitation, that the Committee may
      waive the installment

<PAGE>

      exercise provisions or accelerate the time at which rights may be
      exercised), based on such factors, if any, as the Committee shall
      determine, in its sole discretion. Unless otherwise determined by the
      Committee at grant, (i) in the event the Participant engages in a
      Detrimental Activity prior to any exercise of the Non-Tandem Stock
      Appreciation Right, all Non-Tandem Stock Appreciation Rights held by the
      Participant shall thereupon terminate and expire, (ii) as a condition of
      the exercise of a Non-Tandem Stock Appreciation Right, the Participant
      shall be required to certify (or shall be deemed to have certified) at the
      time of exercise in a manner acceptable to the Company that the
      Participant is in compliance with the terms and conditions of the Plan and
      that the Participant has not engaged in, and does not intend to engage in,
      any Detrimental Activity, and (iii) in the event the Participant engages
      in a Detrimental Activity during the one-year period commencing on the
      date the Non-Tandem Stock Appreciation Right is exercised, the Company
      shall be entitled to recover from the Participant at any time within one
      year after such exercise or vesting, and the Participant shall pay over to
      the Company, an amount equal to any gain realized as a result of the
      exercise (whether at the time of exercise or thereafter). The foregoing
      provisions described in subsections (i), (ii) and (iii) shall cease to
      apply upon a Change in Control.

            (c) Method of Exercise. Subject to whatever installment exercise and
      waiting period provisions apply under subsection (b) above, Non-Tandem
      Stock Appreciation Rights may be exercised in whole or in part in
      accordance with the terms provided by the Committee at grant, by giving
      written notice of exercise to the Company specifying the number of
      Non-Tandem Stock Appreciation Rights to be exercised.

            (d) Payment. Upon the exercise of a Non-Tandem Stock Appreciation
      Right a Participant shall be entitled to receive, for each right
      exercised, up to, but no more than, an amount in cash and/or Common Stock
      (as chosen by the Committee in its sole discretion) equal in value to the
      excess of the Fair Market Value of one share of Common Stock on the date
      the right is exercised over the Fair Market Value of one (1) share of
      Common Stock on the date the right was awarded to the Participant.

      8.5 Limited Stock Appreciation Rights. The Committee may, in its sole
discretion, grant Tandem and Non-Tandem Stock Appreciation Rights either as a
general Stock Appreciation Right or as a Limited Stock Appreciation Right.
Limited Stock Appreciation Rights may be exercised only upon the occurrence of a
Change in Control or such other event as the Committee may, in its sole
discretion, designate at the time of grant or thereafter. Upon the exercise of
Limited Stock Appreciation Rights, except as otherwise provided in an Award
agreement or grant letter, the Participant shall receive in cash or Common
Stock, as determined by the Committee, an amount equal to the amount (i) set
forth in Section 8.2(d) with respect to Tandem Stock Appreciation Rights or (ii)
set forth in Section 8.4(d) with respect to Non-Tandem Stock Appreciation
Rights.

                                    RESERVED

                                  Article 10.
                            OTHER STOCK-BASED AWARDS

      10.1 Other Awards. Other Stock-Based Awards (including, without
limitation, restricted stock units) may be granted either alone or in addition
to or in tandem with Stock Options, Stock Appreciation Rights and Restricted
Stock.

      10.2 Committee. Subject to the provisions of the Plan, the Committee shall
have authority to determine the persons to whom and the time or times at which
such Awards shall be made, the number of shares of Common Stock to be awarded
pursuant to such Awards, and all other conditions of the Awards.

      10.3 Terms and Conditions. Other Stock-Based Awards made pursuant to this
Article 10 shall be subject to the following terms and conditions:

            (a) Non-Transferability. Subject to the applicable provisions of the
      Award agreement or grant letter and the Plan, shares of Common Stock
      subject to Awards made under this Article 10 may not be Transferred prior
      to the date on which the shares are issued, or, if later, the date on
      which any applicable restriction or deferral period lapses.

            (b) Dividends. Unless otherwise determined by the Committee at the
      time of award, subject to the provisions of the Award agreement or grant
      letter and the Plan, the recipient of an Award under this Article 10 shall
      be entitled to receive, currently or on a deferred basis, dividends or
      dividend equivalents with respect to the number of shares of Common Stock
      covered by the Award, as determined at the time of the Award by the
      Committee, in its sole discretion.

            (c) Vesting. Any Award under this Article 10 and any Common Stock
      covered by any such Award shall vest or be forfeited to the extent so
      provided in the Award agreement or grant letter, as determined by the
      Committee, in its sole discretion.

            (d) Waiver of Limitation. The Committee may, in its sole discretion,
      waive in whole or in part any or all of the limitations imposed hereunder
      (if any) with respect to all or any portion of an Award under this Article
      10.

            (e) Price. Common Stock or Other Stock-Based Awards issued on a
      bonus basis under this Article 10 may be issued for no cash consideration;
      Common Stock or Other Stock-Based Awards purchased pursuant to a purchase
      right awarded under this Article 10 shall be priced as determined by the
      Committee. Subject to Section 4.3, the purchase price of shares of Common
      Stock or Other Stock-Based Awards may be zero to the extent permitted by
      applicable law, and, to the extent not so permitted, such purchase price
      may not be less than par value. The purchase of shares of Common Stock or
      Other Stock-Based Awards may be made on either an after-tax or pre-tax
      basis, as determined by the Committee; provided, however, that if the
      purchase is made on a pre-tax basis,

      such purchase shall be made pursuant to a deferred compensation program
      established by the Committee, which will be deemed a part of the Plan.

                                  Article 11.
                 NON-TRANSFERABILITY AND TERMINATION PROVISIONS

      The terms and conditions of this Article 11 shall apply to Awards under
the Plan as follows:

      11.1 Nontransferability. No Stock Option or Stock Appreciation Right shall
be Transferable by the Participant otherwise than by will or by the laws of
descent and distribution. All Stock Options and all Stock Appreciation Rights
shall be exercisable, during the Participant's lifetime, only by the Participant
or his or her legal guardian or representative. Tandem Stock Appreciation Rights
shall be Transferable, solely to the extent permitted above, only with the
underlying Stock Option. In addition, except as provided above, no Stock Option
shall be Transferred (whether by operation of law or otherwise), and no Stock
Option shall be subject to execution, attachment or similar process. Upon any
attempt to Transfer any Stock Option, or in the event of any levy upon any Stock
Option by reason of any execution, attachment or similar process contrary to the
provisions hereof, such Stock Option shall immediately terminate and become null
and void. Notwithstanding the foregoing, the Committee may determine at the time
of grant or thereafter that a Non-Qualified Stock Option that is otherwise not
Transferable pursuant to this Article 11 is Transferable to a Family Member in
whole or in part and in such circumstances, and under such conditions, as
specified by the Committee. A Non-Qualified Stock Option that is Transferred to
a Family Member pursuant to the preceding sentence may not be subsequently
Transferred by such Family Member. Shares of Restricted Stock under Article 7
may not be Transferred prior to the date on which shares are issued, or, if
later, the date on which any applicable restriction or deferral period lapses.
No Award shall, except as otherwise specifically provided by law or herein, be
Transferable in any manner, and any attempt to Transfer any such Award shall be
void, and no such Award shall in any manner be liable for or subject to the
debts, contracts, liabilities, engagements or torts of any person who shall be
entitled to such Award, nor shall it be subject to attachment or legal process
for or against such person. Notwithstanding the foregoing, the Committee may
determine at grant or thereafter that, to the extent consistent with treatment
as an Incentive Stock Option, an Incentive Stock Option may be Transferred by a
Participant to a trust if, under Section 671 of the Code and applicable State
law, the Participant is considered the sole beneficial owner of such Option
while it is held in the trust.

      11.2 Termination of Service. Unless otherwise determined by the Committee
at grant or, if no rights are reduced, thereafter, the following rules apply
with regard to the Termination of Service of a Participant:

            (a) Termination by Reason of Death, Retirement or Disability. If a
      Participant's Termination of Service is by reason of death, Retirement or
      Disability, any Stock Option or Stock Appreciation Right held by such
      Participant, unless otherwise determined by the Committee at grant or, if
      no rights of the Participant (or his estate) are reduced, thereafter, may
      be exercised, to the extent exercisable at the time of such

<PAGE>

      termination, by the Participant or, if applicable, the Participant's or
      the estate's legal representative, at any time within a period of one (1)
      year from the date of such Termination of Service, but in no event beyond
      the expiration of the stated term of such Stock Option or Stock
      Appreciation Right; provided, however, that, if the Participant's
      Termination of Service is due to Disability or Retirement and the
      Participant dies within one year after such termination, any unexercised
      Stock Option or Stock Appreciation Right held by such Participant shall
      thereafter be exercisable, to the extent to which it was exercisable at
      the time of death, for a period of one (1) year (or such other period as
      the Committee may specify at grant or, if no rights of the Participant's
      estate are reduced, thereafter) from the date of such death, but in no
      event beyond the expiration of the stated term of such Stock Option or
      Stock Appreciation Right.

            (b) Voluntary Resignation or Involuntary Termination Without Cause.
      If a Participant's Termination of Service is due to a voluntary
      resignation or by involuntary termination without Cause and such
      termination occurs prior to, or more than ninety (90) days after, the
      occurrence of an event that would be grounds for Termination of Service by
      the Company for Cause (without regard to any notice or cure period
      requirements), any Stock Option or Stock Appreciation Right held by such
      Participant, unless otherwise determined by the Committee at grant or, if
      no rights of the Participant are reduced, thereafter, may be exercised, to
      the extent exercisable at termination, by the Participant at any time
      within a period of ninety (90) days after the date of a Termination of
      Service without Cause or a voluntary resignation, but in no event beyond
      the expiration of the stated term of such Stock Option or Stock
      Appreciation Right.

            (c) Termination for Cause. Unless otherwise determined by the
      Committee at grant or, if no rights of the Participant are reduced,
      thereafter, if a Participant's Termination of Service is for Cause for any
      reason, any Stock Option or Stock Appreciation Right held by such
      Participant shall thereupon terminate and expire as of the date of
      termination. In the event the termination is an involuntary termination
      without Cause or is a voluntary resignation within ninety (90) days after
      occurrence of an event that would be grounds for Termination of Service by
      the Company for Cause (without regard to any notice or cure period
      requirement), any Stock Option or Stock Appreciation Right held by the
      Participant at the time of occurrence of the event that would be grounds
      for Termination of Service by the Company for Cause shall be deemed to
      have terminated and expired upon occurrence of the event that would be
      grounds for Termination of Service by the Company for Cause.

            (d) Termination of Service and Restricted Stock. Subject to the
      applicable provisions of the Restricted Stock Award agreement or grant
      letter and the Plan, upon a Participant's Termination of Service for any
      reason during the relevant Restriction Period, all Restricted Stock still
      subject to restriction will vest or be forfeited in accordance with the
      terms and conditions established by the Committee at grant or thereafter.

            (e) Termination of Service and Other Stock-Based Awards. Subject to
      the applicable provisions of the Award agreement or grant letter and the
      Plan, upon a

<PAGE>

      Participant's Termination of Service for any reason, the Award in question
      will vest or be forfeited or be payable in accordance with the terms and
      conditions established by the Committee at grant or thereafter.

            (f) Unvested Stock Options. Unless otherwise determined by the
      Committee at grant, or if no rights of the Participant are reduced,
      thereafter, Stock Options that are not vested as of the date of a
      Participant's Termination for any reason shall terminate and expire as of
      the date of such Termination.

                                  Article 12.
                          CHANGE IN CONTROL PROVISIONS

      12.1 Benefits. In the event of a Change in Control of the Company (as
defined below), and except as otherwise provided by the Committee in an Award
agreement, a Participant's unvested Award shall not vest and a Participant's
Award shall be treated in accordance with one or more of the following methods
as determined by the Committee:

            (a) All unvested Stock Options, Stock Appreciation Rights,
      Restricted Stock and Other Stock-Based Awards shall become fully vested
      upon a Change in Control, including, without limitation, the restrictions
      to which any shares of Restricted Stock of a Participant granted prior to
      the Change in Control are subject shall lapse as if the applicable
      Restriction Period had ended upon such Change in Control.

            (b) Awards, whether or not then vested, shall be continued, assumed,
      have new rights substituted therefor or be treated in accordance with
      Section 4.2(d) hereof, as determined by the Committee, and restrictions to
      which any shares of Restricted Stock or any other Award granted prior to
      the Change in Control are subject shall not lapse upon a Change in Control
      and the Restricted Stock or other Award shall, where appropriate in the
      sole discretion of the Committee, receive the same distribution as other
      Common Stock on such terms as determined by the Committee; provided that,
      the Committee may decide to award additional Restricted Stock or other
      Award in lieu of any cash distribution. Notwithstanding anything to the
      contrary herein, for purposes of Incentive Stock Options, any assumed or
      substituted Stock Option shall comply with the requirements of Treasury
      Regulation Section 1.425-1 (and any amendments thereto).

            (c) The Committee, in its sole discretion, may provide for the
      purchase of any Awards by the Company or an Affiliate for an amount of
      cash equal to the excess of the Change in Control Price (as defined below)
      of the shares of Common Stock covered by such Awards, over the aggregate
      exercise price of such Awards. For purposes of this Section 12.1, "CHANGE
      IN CONTROL PRICE" shall mean the highest price per share of Common Stock
      paid in any transaction related to a Change in Control of the Company. All
      Exercisable Awards of such Participant, if any, granted prior to the
      Change in Control shall be fully vested and immediately exercisable in
      their entirety immediately prior to such Change in Control.

<PAGE>

      12.2 Change in Control. A "CHANGE IN CONTROL" shall mean the occurrence of
any of the following:

            (a) any person (as defined in Section 3(a)(9) of the Exchange Act
      and as used in Sections 13(d) and 14(d) thereof), excluding the Company,
      any Affiliate and any employee benefit plan sponsored or maintained by the
      Company or any Affiliate of the Company (including any trustee of any such
      plan acting in his capacity as trustee), becoming the "beneficial owner"
      (as defined in Rule 13d-3 under the Exchange Act) of securities of the
      Company representing thirty-five percent (35%) of the total combined
      voting power of the Company's then outstanding securities;

            (b) the merger, consolidation or other business combination of the
      Company (a "TRANSACTION"), other than (A) a Transaction involving only the
      Company and one or more of its Affiliates, or (B) a Transaction
      immediately following which the stockholders of the Company immediately
      prior to the Transaction continue to have a majority of the voting power
      in the resulting entity and no person (other than those covered by the
      exceptions in (a) above) becomes the beneficial owner of securities of the
      resulting entity representing more than fifty percent (50%) of the voting
      power in the resulting entity;

            (c) during any period of two (2) consecutive years beginning on or
      after the Effective Date, the persons who were members of the Board
      immediately before the beginning of such period (the "INCUMBENT
      DIRECTORS") ceasing (for any reason other than death) to constitute at
      least a majority of the Board or the board of directors of any successor
      to the Company, provided that, any director who was not a director as of
      the Effective Date shall be deemed to be an Incumbent Director if such
      director was elected to the board of directors by, or on the
      recommendation of or with the approval of, at least two-thirds of the
      directors who then qualified as Incumbent Directors either actually or by
      prior operation of the foregoing unless such election, recommendation or
      approval occurs as a result of an actual or threatened election contest
      (as such terms are used in Rule 14a-11 of Regulation 14A promulgated under
      the Exchange Act or any successor provision) or other actual or threatened
      solicitation of proxies or contests by or on behalf of a person other than
      a member of the Board; or

            (d) the approval by the stockholders of the Company of any plan of
      complete liquidation of the Company or an agreement for the sale of all or
      substantially all of the Company's assets other than the sale of all or
      substantially all of the assets of the Company to a person or persons who
      beneficially own, directly or indirectly, at least fifty percent (50%) or
      more of the combined voting power of the outstanding voting securities of
      the Company at the time of such sale.

Notwithstanding the foregoing, for purposes of the Plan the Registration Date
shall not be considered a Change in Control.

                                  Article 13.
                      TERMINATION OR AMENDMENT OF THE PLAN

      13.1 Notwithstanding any other provision of the Plan, the Board may at any
time, and from time to time, amend, in whole or in part, any or all of the
provisions of the Plan, or suspend or terminate it entirely, retroactively or
otherwise; provided, however, that, unless otherwise required by law or
specifically provided herein, the rights of a Participant with respect to Awards
granted prior to such amendment, suspension or termination may not be impaired
without the consent of such Participant and, provided further, without the
approval of the stockholders of the Company (in accordance with the laws of the
state under which the Company is then organized), to the extent required by
applicable law, listing, registration, quotation system, exchange or other
similar rules, including the applicable provisions of Rule 16b-3, or, with
regard to Incentive Stock Options, Section 422 of the Code, no amendment may be
made that would (i) increase the aggregate number of shares of Common Stock that
may be issued under the Plan or the maximum individual Participant limitations
under Section 4.1(b), (ii) change the classification of employees eligible to
receive Awards under the Plan, (iii) decrease the minimum option price of any
Stock Option, (iv) extend the maximum option period under Section 6.3, (v)
require stockholder approval in order for the Plan to continue to comply with
the applicable provisions of Rule 16b-3 or, with regard to Incentive Stock
Options, Section 422 of the Code or (vi) increase the aggregate number of shares
of Common Stock that may be issued under the Plan, decrease the minimum option
price of any Stock Option or otherwise violate any such law or rule.

      13.2 The Committee may amend the terms of any Award theretofore granted,
prospectively or retroactively, but, subject to Article 4 above or as otherwise
specifically provided herein, no such amendment or other action by the Committee
shall impair the rights of any holder without the holder's consent.

                                  Article 14.
                             UNFUNDED STATUS OF PLAN

      The Plan is intended to constitute an "unfunded" plan for incentive
compensation. With respect to any payments as to which a Participant has a fixed
and vested interest but which are not yet made to a Participant by the Company,
nothing contained herein shall give any such Participant any rights that are
greater than those of a general creditor of the Company.

                                  Article 15.
                               GENERAL PROVISIONS

      15.1 Legend. The Committee may require each person receiving shares of
Common Stock pursuant to an Award under the Plan to represent to and agree with
the Company in writing that the Participant is acquiring the shares without a
view to distribution thereof, and that any subsequent offer for sale or sale of
any such shares of Common Stock shall be made either pursuant to (i) a
registration statement on an appropriate form under the Securities Act of 1933,
which registration statement shall have become effective and shall be current
with respect to the shares of Common Stock being offered and sold, or (ii) a
specific exemption from the registration requirements of the Securities Act of
1933, and that in claiming such exemption the

<PAGE>

Participant will, prior to any offer for sale or sale of shares of Common Stock,
obtain a favorable written opinion, satisfactory in form and substance to the
Company, from counsel acceptable to the Company as to the availability of such
exception. In addition to any legend required by the Plan, the certificates for
such shares may include any legend that the Committee deems appropriate to
reflect any restrictions on Transfer. All certificates for shares of Common
Stock delivered under the Plan shall be subject to such stock transfer orders
and other restrictions as the Committee may deem advisable under the rules,
regulations and other requirements of the Securities and Exchange Commission,
any stock exchange upon which the Common Stock is then listed or any national
securities association system upon whose system the Common Stock is then quoted,
any applicable Federal or state securities law and any applicable corporate law,
and the Committee may cause a legend or legends to be put on any such
certificates to make appropriate reference to such restrictions.

      15.2 Other Plans. Nothing contained in the Plan shall prevent the Board
from adopting other or additional compensation arrangements, subject to
stockholder approval if such approval is required; and such arrangements may be
either generally applicable or applicable only in specific cases.

      15.3 No Right to Employment. Neither the Plan nor the grant of any Award
hereunder shall give any Participant or other employee any right with respect to
continuance of employment by the Company or any Affiliate, nor shall there be a
limitation in any way on the right of the Company or any Affiliate by which an
employee is employed to terminate his employment at any time.

      15.4 Withholding of Taxes. The Company shall have the right to deduct from
any payment to be made to a Participant, or to otherwise require, prior to the
issuance or delivery of any shares of Common Stock or the payment of any cash
hereunder, payment by the Participant of, any Federal, state or local taxes
required by law to be withheld. Upon the vesting of Restricted Stock, or upon
making an election under Section 83(b) of the Code, a Participant shall pay all
required withholding to the Company. At the discretion of the Committee, any
such withholding obligation with regard to any Participant may be satisfied by
reducing the number of shares of Common Stock otherwise deliverable or by
delivering shares of Common Stock already owned. Any fraction of a share of
Common Stock required to satisfy such tax obligations shall be disregarded and
the amount due shall be paid instead in cash by the Participant.

      15.5 Listing and Other Conditions.

            (a) As long as the Common Stock is listed on a national securities
      exchange or system sponsored by a national securities association, the
      issue of any shares of Common Stock pursuant to an Award shall be
      conditioned upon such shares being listed on such exchange or system. The
      Company shall have no obligation to issue such shares unless and until
      such shares are so listed, and the right to exercise any Option with
      respect to such shares shall be suspended until such listing has been
      effected.

<PAGE>

            (b) If at any time counsel to the Company shall be of the opinion
      that any sale or delivery of shares of Common Stock pursuant to an Award
      is or may in the circumstances be unlawful or result in the imposition of
      excise taxes on the Company under the statutes, rules or regulations of
      any applicable jurisdiction, the Company shall have no obligation to make
      such sale or delivery, or to make any application or to effect or to
      maintain any qualification or registration under the Securities Act of
      1933, as amended, or otherwise with respect to shares of Common Stock or
      Awards, and the right to exercise any Option shall be suspended until, in
      the opinion of said counsel, such sale or delivery shall be lawful or will
      not result in the imposition of excise taxes on the Company.

            (c) Upon termination of any period of suspension under this Section
      15.5, any Award affected by such suspension that shall not then have
      expired or terminated shall be reinstated as to all shares available
      before such suspension and as to shares that would otherwise have become
      available during the period of such suspension, but no such suspension
      shall extend the term of any Option.

            (d) A Participant shall be required to supply the Company with any
      certificates, representations and information that the Company requests
      and otherwise cooperate with the Company in obtaining any listing,
      registration, qualification, exemption, consent or approval the Company
      deems necessary or appropriate.

      15.6 Governing Law. The Plan shall be governed and construed in accordance
with the laws of the state under which the Company is then organized (regardless
of the law that might otherwise govern under such state's principles of
conflicts of laws).

      15.7 Construction. Wherever any words are used in the Plan in the
masculine gender, they shall be construed as though they were also used in the
feminine gender in all cases where they would so apply, and wherever any words
are used herein in the singular form, they shall be construed as though they
were also used in the plural form in all cases where they would so apply. Unless
otherwise noted, any determination to be made by the Committee under the Plan
shall be understood to be made by the Committee in its sole and absolute
discretion.

      15.8 Other Benefits. No Award payment under the Plan shall be deemed
compensation for purposes of computing benefits under any retirement plan of the
Company or its Affiliates nor affect any benefits under any other benefit plan
now or subsequently in effect under which the availability or amount of benefits
is related to the level of compensation.

      15.9 Costs. The Company shall bear all expenses included in administering
the Plan, including expenses of issuing Common Stock pursuant to any Awards
hereunder.

      15.10 No Right to Same Benefits. The provisions of Awards need not be the
same with respect to each Participant, and such Awards to individual
Participants need not be the same in subsequent years.

      15.11 Death/Disability. The Committee may in its discretion require the
transferee of a Participant to supply it with written notice of the
Participant's death or Disability and to supply it

<PAGE>

with a copy of the will (in the case of the Participant's death) or such other
evidence as the Committee deems necessary to establish the validity of the
transfer of an Award. The Committee may also require the agreement of the
transferee to be bound by all of the terms and conditions of the Plan. If the
Committee shall find, without any obligation or responsibility of any kind to do
so, that any person to whom payment is payable under the Plan is unable to care
for his or her affairs because of disability, illness or accident, any payment
due may be paid to such person's duly appointed legal representative in such
manner and proportions as the Committee may determine, in it sole discretion.
Any such payment shall be a complete discharge of the liabilities of the
Committee and the Board under the Plan.

      15.12 Section 16(b) of the Exchange Act. All elections and transactions
under the Plan by persons subject to Section 16 of the Exchange Act involving
shares of Common Stock are intended to comply with any applicable exemptive
condition under Rule 16b-3. The Committee may establish and adopt written
administrative guidelines, designed to facilitate compliance with Section 16(b)
of the Exchange Act, as it may deem necessary or proper for the administration
and operation of the Plan and the transaction of business thereunder.

      15.13 Severability of Provisions. If any provision of the Plan shall be
held invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provisions hereof, and the Plan shall be construed and enforced
as if such provisions had not been included.

      15.14 Headings and Captions. The headings and captions herein are provided
for reference and convenience only, shall not be considered part of the Plan,
and shall not be employed in the construction of the Plan.

                                  Article 16.
                       APPROVAL OF BOARD AND STOCKHOLDERS

      The Plan shall not be effective unless and until approved by the Board
and, solely to the extent required by any applicable law (including without
limitation, approval required under Rule 16b-3 or Section 422 of the Code) or
applicable registration, stock exchange, quotation system, listing or similar
rule or regulation, approved by the stockholders of the Company in the manner
set forth in such law, regulation or rule.

                                  Article 17.
                                  TERM OF PLAN

      No Award shall be granted pursuant to the Plan on or after the tenth
anniversary of the earlier of the date the Plan was initially adopted or the
date of stockholder approval (if applicable), but Awards granted prior to such
tenth anniversary may extend beyond that date.

                                  Article 18.
