            terms as the Committee deems appropriate, and shall be exercisable

            by any Optionee who is then subject to Section 16 of the Exchange
            Act within the period ending six months and one day after the date

            and conditions it selects, accelerate the period during which an
            Option vests.

      (b)   No portion of an Option which is unexercisable at Termination of
            Employment, shall thereafter become exercisable, except as may be
            otherwise provided by the Committee either in the Option Agreement

                            MISCELLANEOUS PROVISIONS

SECTION 7.1 -- NOT TRANSFERABLE

      (a)   Options granted under this Plan may not be sold, pledged, assigned,
            or transferred in any manner other than by will or the laws of
            descent and distribution or pursuant to a QDRO, unless and until
            such Options have been exercised, or the shares underlying such
            Options have been issued, and all restrictions applicable to such
            shares have lapsed. No Option or interest or right therein shall be
            liable for the debts, contracts, or engagements of the Optionee or
            his or her successors in interest or shall be subject to disposition
            by transfer, alienation, anticipation, pledge, encumbrance,
            assignment or any other means whether such disposition be voluntary
            or involuntary or by operation of law by judgment, levy, attachment,
            garnishment, or any other legal or equitable proceedings (including
<PAGE>

            bankruptcy), and any attempted disposition thereof shall be null and
            void and of no effect, except to the extent that such disposition is
            permitted by the preceding sentence.

      (b)   During the lifetime of the Optionee, only he or she may exercise an
            Option (or any portion thereof) granted to him or her under the
            Plan, unless it has been disposed of pursuant to a QDRO. After the
            death of the Optionee, any exercisable portion of an Option may,
            prior to the time when such portion becomes unexercisable under the
            Plan or the applicable Option Agreement or other agreement, be
            exercised by his or her personal representative or by any person
            empowered to do so under the deceased Optionee's will or under the
            then applicable laws of descent and distribution.

SECTION 7.2 -- AMENDMENT, SUSPENSION, OR TERMINATION OF THIS PLAN

      Except as otherwise provided in this Section 7.2, this Plan may be wholly
or partially amended or otherwise modified, suspended, or terminated at any time
or from time to time by the Board or the Committee. However, no action of the
Committee or Board that would require stockholder approval as a matter of
applicable law, regulation or rule shall be effective unless such stockholder
approval is obtained. No amendment, suspension or termination of this Plan
shall, without the consent of the holder of Options, alter or impair any rights
or obligations under any Options theretofore granted, unless the Option
Agreement itself otherwise expressly so provides. No Options may be granted
during any period of suspension or after termination of this Plan.

SECTION 7.3 -- CHANGES IN COMMON STOCK OR ASSETS OF THE COMPANY, ACQUISITION, OR
               LIQUIDATION OF THE COMPANY AND OTHER CORPORATE EVENTS

      (a)   Subject to Section 7.3(d), in the event that the Committee
            determines that any dividend or other distribution (whether in the
            form of cash, Common Stock, other securities, or other property),
            recapitalization, reclassification, stock split, reverse stock
            split, reorganization, merger, consolidation, split-up, spin-off,
            combination, repurchase, liquidation, dissolution, or sale,
            transfer, exchange or other disposition of all or substantially all
            of the assets of the Company (including, but not limited to a
            Company Sale), or exchange of Common Stock or other securities of
            the Company, issuance of warrants or other rights to purchase Common
            Stock or other securities of the Company, or other similar corporate
            transaction or event, in the Committee's sole discretion affects the
            Common Stock such that an adjustment is determined by the Committee
            to be appropriate in order to prevent dilution or enlargement of the
            benefits or potential benefits intended to be made available under
            the Plan or with respect to an Option, then the Committee shall, in
            such manner as it may deem equitable, adjust any or all of

                  (i)   The number and kind of shares of Common Stock (or other
                        securities or property) with respect to which Options
                        may be granted under the Plan (including, but not
                        limited to, adjustments of the limitations in Section
                        2.1 on the maximum number and kind of shares which may
                        be issued).

                        securities or property) subject to outstanding Options,

                  (iii) The exercise price with respect to any Option.

            nonrecurring transactions or events affecting the Company, any
            affiliate of the Company, or the financial statements of the Company

            accounting principles, the Committee, in its discretion, is hereby
            authorized to take any one or more of the following actions whenever
            the Committee determines that such action is appropriate in order to
            prevent dilution or enlargement of the benefits or potential
            benefits intended to be made available under the Plan or with
            respect to any Option, to facilitate such transactions or events or
            to give effect to such changes in laws, regulations, or principles:

                  (i)   In its sole discretion, and on such terms and conditions

                        taken prior to the occurrence of such transaction or
                        event and either automatically or upon the Optionee's
                        request, for either the purchase of any such Option for
                        an amount of cash equal to the amount that could have
                        been attained upon the exercise of such Option or
                        realization of the Optionee's rights had such Option
                        been currently exercisable or the replacement of such
                        Option with other rights or property selected by the
                        Committee in its sole discretion;

                  (ii)  In its sole discretion, the Committee may provide,

                        prior to the occurrence of such transaction or event
                        that it cannot be exercised after such event;

                        that for a specified period of time prior to such
                        transaction or event, such Option shall be exercisable
                        as to all shares covered thereby, notwithstanding
                        anything to the contrary in (i) Section 4.4 or (ii) the

      (d)   No adjustment or action described in this Section 7.3 or in any
            other provision of the Plan shall be authorized to the extent that
            such adjustment or action would result in short-swing profits
            liability under Section 16 of the Exchange Act or violate the
            exemptive conditions of Rule 16b-3, unless the Committee determines
            that the Option is not to comply with such exemptive conditions.

been obtained at the end of said twelve-month period, all Options previously
granted under this Plan shall thereupon be cancelled and become null and void.

      The Company shall be entitled to the required payment in cash or deduction
from other compensation payable to each Optionee of any sums required by
federal, state or local tax law to be withheld with respect to the issuance,

Common Stock otherwise issuable under such Option (or allow the return of shares
of Common Stock) having a Fair Market Value equal to the sums required to be
withheld.

provide, in the terms of Option Agreements made under the Plan, or to require
the recipient to agree by separate written instrument, that (a) any proceeds,
gains or other economic benefit actually or constructively received by the
recipient upon any receipt or exercise of an Option, or upon the receipt or
resale of any Common Stock underlying such Option, must be paid to the Company,
and (b) the Option shall terminate and any unexercised portion of such Option
(whether or not

<PAGE>

vested) shall be forfeited, if (i) a Termination of Employment occurs prior to a
specified date, or within a specified time period following receipt or exercise
of the Option, or (ii) the recipient at any time, or during a specified time
period, engages in any activity in competition with the Company, or which is
inimical, contrary, or harmful to the interests of the Company, as further
defined by the Committee.

SECTION 7.8 -- LIMITATIONS APPLICABLE TO SECTION 16 PERSONS

exemptive rule under Section 16 of the Exchange Act (including any amendment to
Rule 16b-3) that are requirements for the application of such exemptive rule,
and, to the extent permitted by applicable law, this Plan and Options granted
hereunder shall be deemed amended to the extent necessary to conform to such
applicable exemptive rule.

SECTION 7.9 -- EFFECT OF PLAN UPON OPTIONS AND COMPENSATION PLANS

      The adoption of this Plan shall not affect any other compensation or
incentive plans in effect for the Company or any Subsidiary. Nothing in this

other forms of incentives or compensation for Employees of the Company or any
Subsidiary or (ii) to grant or assume options or other rights otherwise than

not by way of limitation, the grant or assumption of options in connection with

regulations (including, but not limited to, state and federal securities law and
federal margin requirements) and to such approvals by any listing, regulatory,
or governmental authority as may, in the opinion of counsel for the Company, be
necessary or advisable in connection therewith. Any securities delivered under
this Plan shall be subject to such restrictions, and the person acquiring such
securities shall, if requested by the Company, provide such assurances and
representation to the Company as the Company may deem necessary or desirable to
assure compliance with all applicable legal requirements. To the extent
permitted by applicable law, the Plan and Options granted hereunder shall be

      (1)   Purpose. The CommVault Systems, Inc. 1996 Stock Option Plan (the
            "Plan") has been established by CommVault Systems, Inc. (the
            "Company") to (i) attract and retain persons eligible to participate

            incentives, to achieve long-range goals; (iii) provide incentive
            compensation opportunities that are competitive with those of other
            similar companies; and (iv) further align Participants' interests
            with those of the Company's other stockholders through compensation
            that is based on the Company's common stock; and thereby promote the
            long-term financial interest of the Company and the Subsidiaries,
            including the growth in value of the Company's equity and
            enhancement of long-term stockholder return.

      (2)   Participation. Subject to the terms and conditions of the Plan, the
            Committee shall determine and designate, from time to time, from

            "Optionees" in the Plan.

In addition, the following definition of Eligible Individuals shall be added to
Article I of the Plan, and the term "Employee" shall be replaced with the term
Eligible Individual wherever it is appropriate that such change be made, in
order to comply with the intent of this Amendment:

      Eligible Individual. The term "Eligible Individual" shall mean any
      employee of the Company or a Subsidiary and any consultant, director, or
      other person providing services to the Company or a Subsidiary. An Option
      may be granted to an individual, in connection with hiring, retention or
      otherwise, prior to the date the individual first performs services for
      the Company or the Subsidiaries, provided that such Options

<PAGE>

      shall not become vested prior to the date the individual first performs
      such services.

      Section 3. Effect. Except as amended by this Amendment, the Plan shall
remain in full force and effect and nothing herein shall affect, or be deemed to
be a waiver of, the other terms and provisions of the Plan.

      Section 4. Reference to and Effect on the Plan. On and after the date
which this Amendment becomes effective, each reference in the Plan or this
Amendment to "this plan," "hereunder," "hereof" or words of like import

                                    Section 1
                                     GENERAL

1.1      Purpose. The CommVault Systems, Inc. Long-Term Stock Incentive Plan
         (the "Plan") has been established by CommVault Systems, Inc. (the
         "Company") to (i) attract and retain persons eligible to participate in
         the Plan; (ii) motivate Participants, by means of appropriate
         incentives, to achieve long-range goals; (iii) provide incentive
         compensation opportunities that are competitive with those of other
         similar companies; and (iv) further align Participants' interests with
         those of the Company's other stockholders through compensation that is
         based on the Company's common stock; and thereby promote the long-term
         financial interest of the Company and the Subsidiaries, including the
         growth in value of the Company's equity and enhancement of long-term
         stockholder return.

1.2      Participation. Subject to the terms and conditions of the Plan, the
         Committee shall determine and designate, from time to time, from among
         the Eligible Individuals (including transferees of Eligible Individuals
         to the extent the transfer is permitted by the Plan and the applicable
         Award Agreement), those persons who will be granted one or more Awards
         under the Plan, and thereby become "Participants" in the Plan.

1.3      Operation, Administration, and Definitions. The operation and
         administration of the Plan, including the Awards made under the Plan,
         shall be subject to the provisions of Section 4 (relating to operation
         and administration). Capitalized terms in the Plan shall be defined as
         set forth in the Plan (including the definition provisions of Section
         8).

                                    Section 2
                                OPTIONS AND SARS

2.1      Definitions.

         (a)      The grant of an "Option" entitles the Participant to purchase
                  shares of Stock at an Exercise Price established by the
                  Committee. Any Option granted under this Section 2 may be
                  either an incentive stock option (an "ISO") or a non-qualified
                  option (an "NQO"), as determined in the discretion of the
                  Committee. An "ISO" is an Option that is intended to satisfy
                  the requirements applicable to an "incentive stock option"
                  described in section 422(b) of the Code. An "NQO" is an Option
                  that is not intended to be an "incentive stock option" as that
                  term is described in section 422(b) of the Code.

         (b)      A stock appreciation right (an "SAR") entitles the Participant
                  to receive, in cash or Stock (as determined in accordance with
                  subsection 2.5), value equal to (or otherwise based on) the
                  excess of: (a) the Fair Market Value of a specified number of
                  shares of Stock at the time of exercise; over (b) an Exercise
                  Price established by the Committee.

<PAGE>

2.2      Exercise Price. The "Exercise Price" of each Option and SAR granted
         under this Section 2 shall be established by the Committee or shall be
         determined by a method established by the Committee at the time the
         Option or SAR is granted; provided that, the Exercise Price shall not
         be less than 100% of the Fair Market Value of a share of Stock on the
         date of grant; and further provided that the Exercise Price for an
         Option or SAR with respect to a share of Stock shall not be less than
         the par value of a share of Stock.

2.3      Exercise. An Option and an SAR shall be exercisable in accordance with
         such terms and conditions and during such periods as may be established
         by the Committee.

2.4      Payment of Option Exercise Price. The payment of the Exercise Price of
         an Option granted under this Section 2 shall be subject to the
         following:

         (a)      Subject to the following provisions of this subsection 2.4,
                  the full Exercise Price for shares of Stock purchased upon the
                  exercise of any Option shall be paid at the time of such
                  exercise (except that, in the case of an exercise arrangement
                  approved by the Committee and described in paragraph 2.4(c),
                  payment may be made as soon as practicable after the
                  exercise).

         (b)      The Exercise Price shall be payable in cash or by tendering,
                  by either actual delivery of shares or by attestation, shares
                  of Stock valued at Fair Market Value as of the day of
                  exercise, or in any combination thereof, as determined by the
                  Committee. Except as otherwise provided by the Committee,
                  payments made with shares of Stock shall be limited to shares
                  held by the Participant for not less than six months prior to
                  the payment date.

         (c)      The Committee may permit a Participant to elect to pay the
                  Exercise Price upon the exercise of an Option by irrevocably
                  authorizing a third party to sell shares of Stock (or a
                  sufficient portion of the shares) acquired upon exercise of
                  the Option and remit to the Company a sufficient portion of
                  the sale proceeds to pay the entire Exercise Price and any tax
                  withholding resulting from such exercise.

         (d)      The Committee may permit a Participant to elect to pay the
                  Exercise Price upon the exercise of an Option by delivery of a
                  promissory note containing such terms as the Committee shall
                  establish.

2.5      Settlement of Award. Settlement of Options and SARs is subject to
         subsection 4.7.

         (b)      A "Stock Unit" Award is the grant of a right to receive shares
                  of Stock in the future.

         (c)      A "Performance Share" Award is a grant of a right to receive
                  shares of Stock or Stock Units which is contingent on the
                  achievement of performance or other objectives during a
                  specified period.

         (d)      A "Restricted Stock" Award is a grant of shares of Stock, and
                  a "Restricted Stock Unit" Award is the grant of a right to
                  receive shares of Stock in the future, with such shares of
                  Stock or right to future delivery of such shares of Stock
                  subject to a risk of forfeiture or other restrictions that
                  will lapse upon the achievement of one or more goals relating
                  to completion of service by the Participant, or achievement of
                  performance or other objectives, as determined by the
                  Committee.

3.2      Restrictions on Awards. Each Bonus Stock Award, Stock Unit Award,
         Performance Share Award, Restricted Stock Award and Restricted Stock
         Unit Award shall be subject to such conditions, restrictions and
         contingencies as the Committee shall be subject to the following:

         (a)      Any such Award shall be subject to such conditions,
                  restrictions and contingencies as the Committee shall
                  determine.

         (b)      The Committee may designate whether any such Award being
                  granted to any Participant is intended to be
                  "performance-based compensation" as that term is used in
                  section 162(m) of the Code. Any such Awards designated as
                  intended to be "performance-based compensation" shall be
                  conditioned on the achievement of one or more Performance
                  Measures, to the extent required by Code section 162(m). The
                  Performance Measures established by the Committee may be with
                  respect to corporate performance, operating group or sub-group
                  performance, individual company performance, other group or
                  individual performance, or division performance, may be
                  measured gross or net and may be on a total or per share
                  basis. The Performance Measures that may be used by the
                  Committee for such Awards shall be based on any one or more of
                  the following, as selected by the Committee: earnings (e.g.,
                  earnings before income taxes, or "EBIT"; earnings before
                  income taxes, depreciation and amortization, or "EBITDA";
                  earnings per share, or "EPS"), financial return ratios (e.g.,
                  return on investment, or "ROI"; return on invested capital, or
                  "ROIC"; return on equity, or "ROE"), revenue, operating or net
                  cash flows, total shareholder return, market share, operating
                  income or net income, debt load reduction, expense management,
                  stock price and strategic business objectives, consisting of
                  one or more objectives based on meeting specific cost targets,
                  business expansion goals and goals relating to acquisitions or
                  divestitures. For Awards under this Section 3 intended to be
                  "performance-based compensation," the grant of the Awards and
                  the establishment of the Performance Measures shall be made
                  during the period required under Code section 162(m).

                          OPERATION AND ADMINISTRATION

4.1      Effective Date. Subject to the approval of the stockholders of the
         Company, the Plan shall be effective as of the completion of an initial
         public offering of the Stock (the "Effective Date"); provided, however,
         that to the extent that Awards are granted under the Plan prior to its
         approval by stockholders, the Awards shall be contingent on approval of
         the Plan by the stockholders of the Company. The Plan shall be
         unlimited in duration and, in the event of Plan termination, shall
         remain in effect as long as any Awards under it are outstanding;
         provided, however, that no Awards may be granted under the Plan after
         the ten-year anniversary of the Effective Date (except for Awards
         granted pursuant to commitments entered into prior to such ten-year
         anniversary).

4.2      Shares Subject to Plan. The shares of Stock for which Awards may be
         granted under the Plan shall be subject to the following:

         (a)      The shares of Stock with respect to which Awards may be made
                  under the Plan shall be shares currently authorized but
                  unissued or currently held or, to the extent permitted by
                  applicable law, subsequently acquired by the Company as
                  treasury shares, including shares purchased in the open market
                  or in private transactions.

         (b)      Subject to the following provisions of this subsection 4.2,
                  the maximum number of shares of Stock that may be delivered to
                  Participants and their beneficiaries under the Plan shall be
                  equal to 6,000,000 shares of Stock, plus, if on April 1 of any
                  year in which the Plan is in effect the number of shares of
                  Stock with respect to which Awards may be granted is less than
                  five percent (5%) of the number of outstanding shares of Stock
                  on such date, an annual increase (determined as of April 1 of
                  each year) of an amount of shares such that the total number
                  of shares available for Awards under the Plan is equal to five
                  percent (5%) of the number of outstanding shares of Stock on
                  such date.

         (c)      To the extent provided by the Committee, any Award may be
                  settled in cash rather than Stock. To the extent any shares of
                  Stock covered by an Award are not delivered to a Participant
                  or beneficiary because the Award is forfeited or canceled, or
                  the shares of Stock are not delivered because the Award is
                  settled in cash or used to satisfy the applicable tax
                  withholding obligation, such shares shall not be deemed to
                  have been delivered for purposes of determining the maximum
                  number of shares of Stock available for delivery under the
                  Plan.

         (d)      If the exercise price of any stock option granted under the
                  Plan is satisfied by tendering shares of Stock to the Company
                  (by either actual delivery or by attestation), only the number
                  of shares of Stock issued net of the shares of Stock tendered
                  shall be deemed delivered for purposes of determining the
                  maximum number of shares of Stock available for delivery under
                  the Plan.

         (e)      Subject to paragraph 4.2(f), the following additional maximums
                  are imposed under the Plan:

                                       4
<PAGE>

                  (i)      The maximum number of shares of Stock that may be
                           issued pursuant to Options intended to be ISOs shall
                           be 25,000,000 shares during the duration of the Plan.

                  (ii)     The maximum number of shares that may be covered by
                           Awards granted to any one individual pursuant to
                           Section 2 (relating to Options and SARs) shall be
                           25,000,000 shares during the duration of the Plan. If
                           an Option is in tandem with an SAR, such that the
                           exercise of the Option or SAR with respect to a share
                           of Stock cancels the tandem SAR or Option right,
                           respectively, with respect to such share, the tandem
                           Option and SAR rights with respect to each share of
                           Stock shall be counted as covering but one share of
                           Stock for purposes of applying the limitations of
                           this paragraph (ii).

                  (iii)    For Stock Unit Awards, Performance Share Awards,
                           Restricted Stock Awards or Restricted Unit Awards
                           that are intended to be "performance-based
                           compensation" (as that term is used for purposes of
                           Code section 162(m)), no more than 25,000,000 shares
                           of Stock may be subject to such Awards granted to any
                           one individual during duration of the Plan
                           (regardless of when such shares are deliverable) and
                           if such Awards are settable in cash, no more than
                           $1,000,000 may be subject to such Awards granted to
                           any individual during any one-calendar-year period
                           (regardless of when such amounts are deliverable.

         (f)      In the event of a corporate transaction involving the Company
                  (including, without limitation, any stock dividend, stock
                  split, extraordinary cash dividend, recapitalization,
                  reorganization, merger, consolidation, split-up, spin-off,
                  combination or exchange of shares), the Committee may adjust
                  Awards to preserve the benefits or potential benefits of the
                  Awards. Action by the Committee may include: (i) adjustment of
                  the number and kind of shares which may be delivered under the
                  Plan; (ii) adjustment of the number and kind of shares subject
                  to outstanding Awards; (iii) adjustment of the Exercise Price
                  of outstanding Options and SARs; and (iv) any other
                  adjustments that the Committee determines to be equitable.

4.3      General Restrictions. Delivery of shares of Stock or other amounts
         under the Plan shall be subject to the following:

         (a)      Notwithstanding any other provision of the Plan, the Company
                  shall have no liability to deliver any shares of Stock under
                  the Plan or make any other distribution of benefits under the
                  Plan unless such delivery or distribution would comply with
                  all applicable laws (including, without limitation, the
                  requirements of the Securities Act of 1933, and the applicable
                  requirements of any securities exchange or similar entity.

         (b)      To the extent that the Plan provides for issuance of stock
                  certificates to reflect the issuance of shares of Stock, the
                  issuance may be effected on a non-certificated

                                       5
<PAGE>

                  basis, to the extent not prohibited by applicable law or the
                  applicable rules of any stock exchange.

4.4      Tax Withholding. All distributions under the Plan are subject to
         withholding of all applicable taxes, and the Committee may condition
         the delivery of any shares or other benefits under the Plan on
         satisfaction of the applicable withholding obligations. The Committee,
         in its discretion, and subject to such requirements as the Committee
         may impose prior to the occurrence of such withholding, may permit such
         withholding obligations to be satisfied through (a) cash payment by the
         Participant, (b) through the surrender of shares of Stock which the
         Participant already owns (provided, however, that to the extent shares
         described in this paragraph (b) are used to satisfy more than the
         minimum statutory withholding obligation, as described below, then,
         except as otherwise provided by the Committee, payments made with
         shares of Stock in accordance with this paragraph (b) above shall be
         limited to shares held by the Participant for not less than six months
         prior to the payment date), or (c) through the surrender of shares of
         Stock to which the Participant is otherwise entitled under the Plan;
         provided, however, that such shares under this paragraph (c) may be
         used to satisfy not more than the Company's minimum statutory
         withholding obligation (based on minimum statutory withholding rates
         for Federal and state tax purposes, including payroll taxes, that are
         applicable to such supplemental taxable income).

4.5      Grant and Use of Awards. In the discretion of the Committee, a
         Participant may be granted any Award permitted under the provisions of
         the Plan, and more than one Award may be granted to a Participant.
         Awards may be granted as alternatives to or replacement of awards
         granted or outstanding under the Plan, or any other plan or arrangement
         of the Company or a Subsidiary (including a plan or arrangement of a
         business or entity, all or a portion of which is acquired by the
         Company or a Subsidiary). Subject to the overall limitation on the
         number of shares of Stock that may be delivered under the Plan, the
         Committee may use available shares of Stock as the form of payment for
         compensation, grants or rights earned or due under any other
         compensation plans or arrangements of the Company or a Subsidiary,
         including the plans and arrangements of the Company or a Subsidiary
         assumed in business combinations.

4.6      Dividends and Dividend Equivalents. An Award (including without
         limitation an Option or SAR Award) may provide the Participant with the
         right to receive dividend payments or dividend equivalent payments with
         respect to Stock subject to the Award (both before and after the Stock
         subject to the Award is earned, vested, or acquired), which payments
         may be either made currently or credited to an account for the
         Participant, and may be settled in cash or Stock, as determined by the
         Committee. Any such settlements, and any such crediting of dividends or
         dividend equivalents or reinvestment in shares of Stock, may be subject
         to such conditions, restrictions and contingencies as the Committee
         shall establish, including the reinvestment of such credited amounts in
         Stock equivalents.

4.7      Settlement of Awards. The obligation to make payments and distributions
         with respect to Awards may be satisfied through cash payments, the
         delivery of shares of Stock, the granting of replacement Awards, or
         combination thereof as the Committee shall determine. Satisfaction of
         any such obligations under an Award, which is sometimes

                                       6
<PAGE>

         referred to as "settlement" of the Award, may be subject to such
         conditions, restrictions and contingencies as the Committee shall
         determine. The Committee may permit or require the deferral of any
         Award payment, subject to such rules and procedures as it may
         establish, which may include provisions for the payment or crediting of
         interest or dividend equivalents, and may include converting such
         credits into deferred Stock equivalents. Each Subsidiary shall be
         liable for payment of cash due under the Plan with respect to any
         Participant to the extent that such benefits are attributable to the
         services rendered for that Subsidiary by the Participant. Any disputes
         relating to liability of a Subsidiary for cash payments shall be
         resolved by the Committee.

4.8      Transferability. Except as otherwise provided by the Committee, Awards
         under the Plan are not transferable except as designated by the
         Participant by will or by the laws of descent and distribution.

4.9      Form and Time of Elections. Unless otherwise specified herein, each
         election required or permitted to be made by any Participant or other
         person entitled to benefits under the Plan, and any permitted
         modification, or revocation thereof, shall be in writing filed with the
         Committee at such times, in such form, and subject to such restrictions
         and limitations, not inconsistent with the terms of the Plan, as the
         Committee shall require.

4.10     Agreement With Company. An Award under the Plan shall be subject to
         such terms and conditions, not inconsistent with the Plan, as the
         Committee shall, in its sole discretion, prescribe. The terms and
         conditions of any Award to any Participant shall be reflected in such
         form of written document as is determined by the Committee. A copy of
         such document shall be provided to the Participant, and the Committee
         may, but need not require that the Participant sign a copy of such
         document. Such document is referred to in the Plan as an "Award
         Agreement" regardless of whether any Participant signature is required.

4.11     Action by Company or Subsidiary. Any action required or permitted to be
         taken by the Company or any Subsidiary shall be by resolution of its
         board of directors, or by action of one or more members of the board
         (including a committee of the board) who are duly authorized to act for
         the board, or (except to the extent prohibited by applicable law or
         applicable rules of any stock exchange) by a duly authorized officer of
         such company.

4.12     Gender and Number. Where the context admits, words in any gender shall
         include any other gender, words in the singular shall include the

4.13     Limitation of Implied Rights.

         (a)      Neither a Participant nor any other person shall, by reason of
                  participation in the Plan, acquire any right in or title to
                  any assets, funds or property of the Company or any Subsidiary
                  whatsoever, including, without limitation, any specific funds,
                  assets, or other property which the Company or any Subsidiary,
                  in its sole discretion, may set aside in anticipation of a
                  liability under the Plan. A Participant shall have only a
                  contractual right to the Stock or amounts, if any,

                                       7
<PAGE>

                  payable under the Plan, unsecured by any assets of the Company
                  or any Subsidiary, and nothing contained in the Plan shall
                  constitute a guarantee that the assets of the Company or any
                  Subsidiary shall be sufficient to pay any benefits to any
                  person.

         (b)      The Plan does not constitute a contract of employment, and
                  selection as a Participant will not give any participating
                  employee or other individual the right to be retained in the
                  employ of the Company or any Subsidiary or the right to
                  continue to provide services to the Company or any Subsidiary,
                  nor any right or claim to any benefit under the Plan, unless
                  such right or claim has specifically accrued under the terms
                  of the Plan. Except as otherwise provided in the Plan, no
                  Award under the Plan shall confer upon the holder thereof any
                  rights as a stockholder of the Company prior to the date on
                  which the individual fulfills all conditions for receipt of
                  such rights.

4.14     Evidence. Evidence required of anyone under the Plan may be by
         certificate, affidavit, document or other information which the person
         acting on it considers pertinent and reliable, and signed, made or
         presented by the proper party or parties.

                                    Section 5
                                CHANGE IN CONTROL

         Subject to the provisions of paragraph 4.2(f) (relating to the
adjustment of shares), and except as otherwise provided in the Plan or the Award
Agreement reflecting the applicable Award, (a) upon a Change in Control that is
a merger or consolidation pursuant to which the Company is the surviving
corporation (other than a merger or consolidation pursuant to which the Company
survives but pursuant to which a majority of its outstanding shares of Stock are
converted into securities of another corporation or entity or are exchanged for
other consideration), any Option granted hereunder shall pertain and apply to
the securities which a holder of the number of shares of Stock then subject to
the Option would have been entitled to receive, and (b) upon a Change in Control
that is a dissolution or liquidation of the Company or a merger or consolidation
pursuant to which the Company is not the surviving corporation or pursuant to
which a majority of its outstanding shares of Stock are so converted or
exchanged, every Option hereunder shall terminate; provided, however, that if
any dissolution, liquidation, merger or consolidation described in paragraph (b)
is contemplated, the Company shall either arrange for any corporation succeeding
to the business or assets of the Company to issue to the Participant replacement
awards (which, in the case of ISOs, shall satisfy the requirements of the
Section 424 of the Code) on such corporation's stock or shall make the
outstanding Options fully exercisable (even if they would not otherwise then be
exercisable) at least 20 days before the effective date of any such dissolution,
liquidation, merger or consolidation.

                                    Section 6
                                    COMMITTEE

6.1      Administration. The authority to control and manage the operation and
         administration of the Plan shall be vested in a committee (the
         "Committee") in accordance with this Section 6. The Committee shall be
         the Committee appointed by the Board. If the

                                       8
<PAGE>

         Committee does not exist, or for any other reason determined by the
         Board, the Board may take any action under the Plan that would
         otherwise be the responsibility of the Committee.

6.2      Powers of Committee. The Committee's administration of the Plan shall
         be subject to the following:

         (a)      Subject to the provisions of the Plan, the Committee will have
                  the authority and discretion to select from among the Eligible
                  Individuals those persons who shall receive Awards, to
                  determine the time or times of receipt, to determine the types
                  of Awards and the number of shares covered by the Awards, to
                  establish the terms, conditions, performance criteria,
                  restrictions, and other provisions of such Awards, to make
                  adjustments to Awards to reflect changes in the Participant's
                  relationship with the Company and (subject to the restrictions
                  imposed by Section 7) to cancel or suspend Awards.

         (b)      To the extent that the Committee determines that the
                  restrictions imposed by the Plan preclude the achievement of
                  the material purposes of the Awards in jurisdictions outside
                  the United States, the Committee will have the authority and
                  discretion to modify those restrictions as the Committee
                  determines to be necessary or appropriate to conform to
                  applicable requirements or practices of jurisdictions outside
                  of the United States.

         (c)      The Committee will have the authority and discretion to
                  interpret the Plan, to establish, amend, and rescind any rules
                  and regulations relating to the Plan, to determine the terms
                  and provisions of any Award Agreement made pursuant to the
                  Plan, and to make all other determinations that may be
                  necessary or advisable for the administration of the Plan.

         (d)      Any interpretation of the Plan by the Committee and any
                  decision made by it under the Plan is final and binding on all
                  persons.

         (e)      In controlling and managing the operation and administration
                  of the Plan, the Committee shall take action in a manner that
                  conforms to the articles and by-laws of the Company, and
                  applicable state corporate law.

6.3      Delegation by Committee. Except to the extent prohibited by applicable
         law or the applicable rules of a stock exchange, the Committee may
         allocate all or any portion of its responsibilities and powers to any
         one or more of its members and may delegate all or any part of its
         responsibilities and powers to any person or persons selected by it.
         Any such allocation or delegation may be revoked by the Committee at
         any time.

6.4      Information to be Furnished to Committee. The Company and Subsidiaries
         shall furnish the Committee with such data and information as it
         determines may be required for it to discharge its duties. The records
         of the Company and Subsidiaries as to an employee's or Participant's
         employment (or other provision of services), termination of employment
         (or cessation of the provision of services), leave of absence,
         reemployment and compensation shall be conclusive on all persons unless
         determined to be incorrect.

                                       9
<PAGE>

         Participants and other persons entitled to benefits under the Plan must
         furnish the Committee such evidence, data or information as the
         Committee considers desirable to carry out the terms of the Plan.

                                    Section 7
                            AMENDMENT AND TERMINATION

         The Board may, at any time, amend or terminate the Plan, provided that
no amendment or termination may, in the absence of written consent to the change
by the affected Participant (or, if the Participant is not then living, the
affected beneficiary), adversely affect the rights of any Participant or
beneficiary under any Award granted under the Plan prior to the date such
amendment is adopted by the Board; and further provided that adjustments
pursuant to paragraph 4.2(f) shall not be subject to the foregoing limitations
of this Section 7. Notwithstanding the foregoing, it is the intent of the
Company that the Plan and Awards made hereunder comply with the requirements of
section 409A of the Code. The Board retains the right to amend the Plan, and the
Committee retains the right to amend any Awards made under the Plan, to the
extent it deems necessary or desirable to conform to the requirements of section
409A and applicable guidance issued thereunder.

                                    Section 8

                           agreement to merge the Company into or consolidate
                           the Company with another entity, sell or otherwise
                           dispose of all or substantially all of its assets or
                           adopt a plan of liquidation, provided that if the
                           merger, consolidation, sale of assets or liquidation
                           is not consummated for any reason, then no Change in

                           in Control shall be deemed to have occurred as of the
                           date of the consummation of the transaction;
                           provided, however, that a Change in Control shall not

                           transaction, or a substantially concurrent or
                           otherwise related series of transactions, upon the

                           in the same proportion) as held the beneficial
                           ownership of the voting power of the Company
                           immediately prior to the transaction or the
                           substantially concurrent or otherwise related series
                           of transactions, except that upon the completion
                           thereof, employees or employee benefit plans of the
                           Company may be a new holder of such beneficial
                           ownership; provided, further, that a transaction with
                           an "Affiliate" of the Company (as defined in the
                           Exchange Act) shall not be treated as a Change in
                           Control; or

                  (ii)     the "beneficial ownership" (as defined in Rule 13d-3
                           under the Exchange Act) of securities representing
                           50% or more of the combined voting power of the
                           Company is acquired, other than from the Company, by
                           any "person" as defined in Sections 13(d) and 14(d)
                           of the Exchange Act (other than by an Affiliate or
                           any trustee or other fiduciary holding securities
                           under an employee benefit or other similar stock plan
                           of the Company); or

                  (iii)    at any time during any period of two consecutive
                           years, individuals who at the beginning of such

                           to constitute at least a majority thereof (unless the
                           election, or the nomination for election by the

                           election or nomination who were directors at the
                           beginning of such period).

                  Notwithstanding the foregoing, Change in Control shall not be
                  deemed any change due to a public offering of Stock or any
                  other securities of the Company.

         (d)      Code. The term "Code" means the Internal Revenue Code of 1986,
                  as amended. A reference to any provision of the Code shall
                  include reference to any successor provision of the Code.

         (e)      Eligible Individual. The term "Eligible Individual" shall mean
                  any employee of the Company or a Subsidiary and any
                  consultant, director, or other person providing services to
                  the Company or a Subsidiary; provided however, that an ISO may
                  only be granted to an employee of the Company or a Subsidiary.
                  An Award may be granted to an individual, in connection with
                  hiring, retention or otherwise, prior to the date the
                  individual first performs services for the Company or the
                  Subsidiaries, provided that such Awards shall not become
                  vested prior to the date the individual first performs such
                  services.

         (f)      Fair Market Value. For purposes of determining the "Fair
                  Market Value" of a share of Stock as of any date, the
                  following rules shall apply:

                  (i)      If, as of the date for which a determination is to be
                           made, the principal market for the Stock is a
                           national securities exchange or the Nasdaq stock
                           market, then the "Fair Market Value" shall be the

<PAGE>

                           Stock on the principal exchange or market on which
                           the Stock is then listed or admitted to trading
                           determined as of the business day preceding the date
                           for which the determination is to be made.

                  (ii)     If, as of the date for which a determination is to be
                           made, the sale prices are not available or the
                           principal market for the Stock is not a national
                           securities exchange and the Stock is not quoted on
                           the Nasdaq stock market, then the "Fair Market Value"
                           shall be the closing price for the Stock as reported
                           on the Nasdaq OTC Bulletin Board Service or by the
                           National Quotation Bureau, Incorporated or a
                           comparable service determined as of the business day
                           preceding the date for which the determination is to
                           be made.

                  (iii)    If, in accordance with rules established by the
                           Committee, a determination of "Fair Market Value" is
                           required as of any date and, as of that date,
                           paragraphs (i) and (ii) next above are inapplicable,
                           then the "Fair Market Value" as of that date shall be
                           determined by a nationally-recognized appraisal or
                           investment banking firm experienced in appraising
                           businesses, or by such other person, employee or
                           entity as shall be determined by the Committee from
                           time to time or such other method as the Committee
                           may decide in its sole discretion, with such
                           valuation to be performed in accordance with such
                           rules and considerations as are established by the
                           Committee. The Company shall bear the fees and
                           expenses of such valuation.

         (g)      Stock. The term "Stock" shall mean shares of common stock of
                  the Company.

         (h)      Subsidiaries. The term "Subsidiary" means any company during
                  any period in which it is a "subsidiary corporation" (as that
                  term is defined in Code section 424(f)) with respect to the
                  Company.
