(4)         DELEGATION OF CERTAIN RESPONSIBILITIES. The Committee may, in its
            sole discretion, delegate to appropriate officers of the Company the
            administration of this Plan; provided, however, that no such
            delegation by the Committee shall be made (i) if such delegation
            would not be permitted under applicable law or (ii) with respect to
            the administration of this Plan as it affects executive officers or
            directors of the Company, and provided further that the Committee
            may not delegate its authority to correct errors, omissions or
            inconsistencies in this Plan. Subject to the above limitations, the
            Committee may delegate to the President or Chief Executive Officer
            of the Company its authority under this Section 3 to grant Awards to
            employees who are not executive officers or directors of the
            Company. All authority delegated by the Committee under this Section
            3(4) shall be exercised in accordance with the provisions of this
            Plan and any guidelines for, conditions on, or limitations to the
            exercise of such authority that may from time to time be established
            by the Committee.

(5)         AWARD AGREEMENTS. Each Award under this Plan shall be evidenced by
            an Award Agreement which shall be signed by an officer of the
            Company and by the Participant, and shall contain such terms and
            conditions as may be approved by the Committee, which need not be
            the same in all cases. Any Award Agreement may be supplemented or
            amended in writing from time to time as approved by the Committee,
            provided that the terms of such agreements as amended or
            supplemented, as well as the terms of the original Award Agreement,
            are not inconsistent with the provisions of this Plan. Nothing
            contained in this Plan or any resolutions adopted or to be adopted
            by the Board or by the shareholders of the Company shall constitute
            the granting of an Award under this Plan. A Service Provider who
            receives an Award under this Plan shall not, with respect to such
            Award, be deemed to have become a Participant, or to have any rights
            with respect to such Award, unless and until such Service Provider
            has executed an Award Agreement or other instrument evidencing the
            Award and shall have delivered an executed copy thereof to the
            Company, and has otherwise complied with the applicable terms and
            conditions of the Award.

(6)         AWARDS TO OFFICERS AND DIRECTORS. Awards to officers shall be
            granted by the Committee. If the Committee is not composed as
            prescribed in the definition of Committee above, the Board may take
            such action with respect to any Award to an officer as it deems
            necessary or advisable to comply with Rule 16b-3 of the Securities
            Exchange Act of 1934 and any related rules.

SECTION 4   SHARES AVAILABLE FOR AWARDS.

(1)         SHARES AVAILABLE. Subject to adjustment as provided in Section 4(3),
            the number of Shares with respect to which Awards may be granted
            under this Plan shall be 1,500,000.

(2)         TERMINATIONS AND CANCELLATIONS. If, after the effective date of this
            Plan, an Award otherwise terminates or is cancelled without the
            delivery of Shares or of other consideration, then the Shares
            covered by such Award, or to which such Award relates, or the number
            of Shares otherwise counted against the aggregate number of Shares
            with respect to which Awards may be granted, to the extent of any
            such termination or cancellation, shall again be Shares with respect
            to which Awards may be granted.

(3)         ADJUSTMENTS. In the event that the Committee determines that any
            dividend or other distribution (whether in the form of cash, Shares,
            other securities, or other property), recapitalization, stock split,
            reverse stock split, reorganization, merger, consolidation,
            split-up, spin-off, combination, repurchase, or exchange of Shares
            or other securities of the Company, issuance of warrants or other
            rights to purchase Shares or other securities of the Company, or
            other similar corporate transaction or event affects the Shares 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 this Plan,
            then the Committee shall, in such manner as it may deem equitable,
            adjust any or all of (i) the number of Shares or the kind of equity
            securities of the Company (or the number and kind of other
            securities or property) with respect to which Awards may be granted,
            (ii) the number of Shares or the kind of equity securities of the
            Company (or the number and kind of other securities or property)
            subject to outstanding Awards, and (iii) the grant or exercise price
            with respect to any Award or, if deemed appropriate, make provision
            for a cash payment to the holder of an outstanding Award; provided,
            however, that any adjustment of an Incentive Stock Option shall be
            made in such a manner so as not to constitute a "modification"
            within the meaning of Section 424(h)(3) of the Code; and provided
            further, that the number of Shares subject to any Award denominated
            in Shares shall always be a whole number.

(4)         SOURCES OF SHARES DELIVERABLE UNDER AWARDS. Any Shares delivered
            pursuant to an Award may consist, in whole or in part, of authorized
            and unissued Shares.

(5)         SINGLE PARTICIPANT LIMITATION. The aggregate number of Shares
            reserved for issuance to any one Participant upon the exercise of
            Options shall not exceed five percent (5%) of the total number of
            Shares outstanding from time to time, provided that any reduction in
            the number of outstanding Shares shall not affect any Option granted
            hereunder prior to the reduction.

SECTION 5   ELIGIBILITY.

Employees, Non-Employee Directors and Consultants of the Company or any
Affiliate shall be eligible to be designated as Participants.

SECTION 6   STOCK OPTIONS.

(1)         GRANT. Subject to the provisions of this Plan, the Committee shall
            have the authority to determine the Employees, Consultants and
            Non-Employee Directors to whom Options shall be granted, the number
            of Shares to be covered by each Option, the option price therefor
            and the conditions and limitations applicable to the exercise of the
            Option; provided, however, that the terms and conditions of any
            Incentive Stock Option granted hereunder shall be subject to, and
            shall comply in all respects with, the requirements of Section 422
            of the Code, as amended from time to time. The Committee shall have
            the authority to grant Incentive Stock Options, or to grant
            Non-Qualified Stock Options, or to grant both types of options;
            provided, however that Incentive Stock Options shall not be granted
            to Consultants, Non-Employee Directors, or any other persons who are
            not permitted to receive Incentive Stock Options under the Code.

(2)         NUMBER OF SHARES. Each Award Agreement covering Options shall state
            that it covers a specified number of Shares, as determined by the
            Committee.


                                       5

(3)         PRICE. The price at which each Share covered by an Option may be
            purchased shall be determined in each case by the Committee and set
            forth in the Award Agreement related to such Option, but in no event
            shall the option price for each Share covered by an Incentive Stock
            Option be less than the Fair Market Value of a Share on the date the
            Option is granted; provided, however, that the Option Price for each
            Share covered by an Incentive Stock Option granted to an Employee
            who then owns stock possessing more than 10% of the total combined
            voting power of all classes of stock of the Company or any parent or
            subsidiary corporation of the Company must be at least 110% of the
            Fair Market Value of the Shares subject to the Incentive Stock
            Option on the date the Option is granted.

(4)         DURATION OF OPTIONS. Each Award Agreement covering Options shall
            state the period of time, determined by the Committee, within which
            the Option may be exercised by the Participant (the "OPTION
            PERIOD"). The Option Period must expire, in all cases, not more than
            ten years from the date an Option is granted; provided, however,
            that the Option Period of an Incentive Stock Option granted to an
            Employee who then owns stock possessing more than 10% of the total
            combined voting power of all classes of stock of the Company or any
            parent or subsidiary corporation of the Company must expire not more
            than five years from the date such an Option is granted. Each Award
            Agreement shall also state the periods of time, if any, as
            determined by the Committee, when incremental portions of each
            Option shall vest. If any Option is not exercised during its Option
            Period, it shall be deemed to have been forfeited and or no further
            force or effect.

(5)         CASH ELECTION. A Participant may, rather than exercise Options which
            he or she is entitled to exercise under Section 6(4), elect to
            require the Corporation to purchase for cancellation any such
            Options, in whole or in part, and, in lieu of receiving the Shares
            to which the purchased Options relate (the "DESIGNATED SHARES"), to
            receive (a) cash payment of an amount equal to the product of the
            number of Designated Shares multiplied by the difference between the
            Fair Market Value and the exercise price per share of the Designated
            Shares, less any amount withheld on account of income taxes, which
            withheld income taxes or will be remitted by the Corporation or (b)
            to receive that number of Common Shares, disregarding fractions,
            which have an aggregate Fair Market Value equal to the product of
            the number of Designated Shares multiplied by the difference between
            the Fair Market Value and the exercise price per share of the
            Designated Shares, less any amount withheld on account of income
            taxes, which withheld income taxes will be remitted by the
            Corporation. For the purposes of this section, the Fair Market Value
            per share shall be the weighted average trading price of the Shares
            during the five days immediately preceding the date of the
            Participant's election herein.

(6)         TERMINATION OF SERVICE, DEATH, DISABILITY, ETC. Except as otherwise
            determined by the Committee, each Award Agreement covering Options
            shall provide as follows with respect to the exercise of the
            Options:

            (a)         If the Participant is terminated as a Service Provider
                        within the Option Period "for cause," the Option shall
                        thereafter be void for all purposes. As used in this
                        Sectopm 6(6)(a), "cause" shall mean (y) the intentional
                        disregard of, or a gross violation of, the Company's
                        established policies and procedures, as determined by
                        the Company or the Committee, and (z) if applicable, as
                        set forth in any employment or similar agreement between
                        the Participant and the Company. The

   7


                        effect of this Section 6(6)(a) shall be limited to
                        determining the consequences of a termination, and
                        nothing in this Section 6(6)(a) shall restrict or
                        otherwise interfere with the Company's discretion with
                        respect to the termination of any Service Provider;

            (b)         If the Participant ceases to be a Service Provider due
                        to the Participant's Retirement, the Option may be
                        exercised by the Participant, within three months
                        following his or her Retirement if the Option is an
                        Incentive Stock Option or within twelve months following
                        his or her Retirement if the Option is a Non-Qualified
                        Stock Option (provided in each case that such exercise
                        must occur within the Option Period), but not
                        thereafter. In any such case, the Option may be
                        exercised only as to the Shares as to which the Option
                        had become exercisable on or before the date the
                        Participant ceases to be a Service Provider;

            (c)         If the Participant dies while he or she is a Service
                        Provider or within the three-month period following the
                        Participant's Retirement, the Option may be exercised by
                        those entitled to do so under the Participant's will or
                        by the laws of descent and distribution within twelve
                        months following the Participant's death (provided that
                        such exercise must occur within the Option Period), but
                        not thereafter. In any such case, the Option may be
                        exercised only as to the Shares as to which the Option
                        had become exercisable on or before the date of the
                        Participant's death or at such time as the Participant
                        ceased to be a Service Provider, whichever is earlier;

            (d)         If the Participant suffers a Disability while a Service
                        Provider, Options held by the Participant may be
                        exercised by the Participant within twelve months
                        following the date the Participant ceases to be a
                        Service Provider (provided that such exercise must occur
                        within the Option Period), but not thereafter. In any
                        such case, the Option may be exercised only as to the
                        Shares as to which the Option had become exercisable on
                        or before the date the Participant ceased to be a
                        Service Provider;

            (e)         If the Participant ceases to be a Service Provider
                        within the Option Period for any reason other than
                        cause, Retirement, Disability or the Participant's
                        death, the Option may be exercised by the Participant
                        within three months following the date of such cessation
                        (provided that such exercise must occur within the
                        Option Period), but not thereafter. In any such case,
                        the Option may be exercised only as to the Shares as to
                        which the Option had become exercisable on or before the
                        date that the Participant ceases to be a Service
                        Provider;

            (f)         Notwithstanding the provisions of this Section 6(6) or
                        any other provision of the plan, with respect to any
                        Options granted to an Employee in connection with the
                        commencement of employment as an Employee, the Committee
                        may provide for terms as to retirement, disability,
                        death or other termination of employment which are
                        different from the terms provided in this Section 6(6)
                        if such different terms are set forth in a written
                        employment agreement with the Employee, which agreement
                        shall have been approved by the Board, or are otherwise
                        provided by the Committee, subject to the approval by
                        the Board. Notwithstanding the foregoing, no Incentive
                        Stock Options may be granted pursuant to this Section
                        6(6)(f);


                                       7

            (g)         Whether an authorized leave of absence or absence due to
                        active military service shall constitute termination as
                        a Service Provider shall be determined by the Committee
                        at the time thereof. Notwithstanding the foregoing, in
                        the case of Incentive Stock Options, if the period of
                        leave exceeds ninety (90) days, unless the individual's
                        right to re-employment is guaranteed by statute or
                        contract, the employment relationship will be deemed to
                        have terminated on the ninety-first (91st) day of such
                        leave; and

            (h)         If a Participant's status as a particular type of
                        Service Provider changes to another type of Service
                        Provider, the Committee, in its discretion, may
                        determine that any Option previously granted shall
                        continue in full force and effect so long as the Option
                        is a Non-Qualified Stock Option. The Committee shall be
                        permitted, in its discretion, to grant Non-Qualified
                        Stock Options which provide that they shall continue in
                        full force and effect if the Participant's status with
                        the Company or any Affiliate changes, but such person
                        continues as a Service Provider.

(7)         LIMITATION ON AMOUNT OF INCENTIVE STOCK OPTIONS. The aggregate fair
            market value (determined as of the time the Option is granted) of
            Shares with respect to which Incentive Stock Options are exercisable
            for the first time by a Participant during any calendar year under
            this Plan (and all other incentive stock option plans of the
            Company, any subsidiary or parent corporation of the Company) shall
            not exceed US$100,000. In no event, however, shall an acceleration
            of exercisability pursuant to the terms of this Plan operate to
            reduce or limit the number of shares which may be exercised pursuant
            to such Incentive Stock Options. Shares in excess of the US$100,000
            limit described herein which become exercisable as a result of
            acceleration shall be treated as Shares subject to a Non-Qualified
            Stock Option.

SECTION 7   TERMS AND CONDITIONS.

(1)         AWARDS MAY BE GRANTED SEPARATELY OR TOGETHER. Awards may, in the
            discretion of the Committee, be granted either alone or in addition
            to, or in substitution for, any other Award granted under this Plan.
            Except as otherwise provided herein, Awards granted in addition to
            other Awards may be granted either at the same time as, or at a

            the Committee shall determine, including, without limitation, cash,
            other securities, other Awards or other property, or any combination
            thereof, and may be made in a single payment or transfer, in
            installments, or on a deferred basis, in each case in accordance
            with rules and procedures established by the Committee.

(3)         LIMITS ON TRANSFER OF AWARDS. An Award shall not be transferable
            other than by will or the laws of descent and distribution, and an
            Option subject to exercise may be exercised, during the lifetime of
            the Participant, only the Participant or in the event of death, the
            Participant's beneficiary as hereinafter provided, or in the event
            of disability, the Participant's personal representative.

(4)         TERM OF AWARDS. Unless otherwise provided herein, the term of each
            Award shall be for such period as may be determined by the
            Committee.

(5)         SHARE CERTIFICATES. All certificates for Shares or other securities
            of the Company or any Affiliate delivered under this Plan pursuant
            to any Award, or the exercise thereof, shall be subject to such stop
            transfer orders and other restrictions as the Committee may deem
            advisable under this Plan or the rules, regulations, and other
            requirements of the SEC, any stock exchange upon which such Shares
            or other securities are then listed, and any applicable Federal or
            state laws, and the Committee may cause a legend or legends to be
            put on any such certificates to make appropriate reference to such
            restrictions.

(6)         CONSIDERATION FOR GRANTS. Awards may be granted for no cash
            consideration or for such minimal cash consideration as may be
            required by applicable law.

(7)         DELIVERY OF SHARES OR OTHER SECURITIES AND PAYMENT BY PARTICIPANT OF
            CONSIDERATION. No Shares or other securities shall be delivered
            pursuant to any Award until payment in full of any amount required
            to be paid pursuant to this Plan or the applicable Award Agreement
            is, or is arranged to be (on terms acceptable to the Committee),
            received by the Company. Such payment may be made by such method or
            methods and in such form or forms as the Committee shall determine,
            including, without limitation, cash, Shares, other securities, other
            Awards or other property, or any combination thereof; provided that
            the combined value, as determined by the Committee, of all cash and
            cash equivalents and the Fair Market Value of any such Shares or
            other property so tendered, or arranged to be tendered, to the
            Company, as of the date of such tender, is at least equal to the
            full amount required to be paid pursuant to this Plan or the
            applicable Award Agreement to the Company.

(8)         CANCELLATION OR SUSPENSION OF AWARDS. The Committee shall have full
            power and authority to determine whether, to what extent and under
            what circumstances any Award shall be canceled or suspended. In
            particular, but without limitation, all outstanding Awards to any
            Participant shall be canceled if the Participant, without the
            consent of the Committee, while employed by or providing services
            for the Company or after termination of such employment or services,
            becomes associated with, employed by, renders services to, or owns
            any interest in (other than any nonsubstantial interest, as
            determined by the Committee), any business that is in competition
            with the Company or with any business in which the Company has a
            substantial interest as determined by the Committee.

(9)         CONDITIONS AND RESTRICTIONS ON AWARDS. At the time that an Award is
            granted, the Committee may provide for any conditions and/or
            restrictions which it intends to impose upon the Award and/or the
            Shares subject to the Award. The Committee may accelerate the
            vesting of any Participant's Option by giving written notice to the
            Participant. Upon receipt of such notice, the Participant and the
            Company shall amend the Award Agreement to reflect the new vesting
            schedule. The acceleration of the exercise period of an Option shall
            not affect the expiration date of that Option. Notwithstanding the
            Committee's discretion in determining a vesting schedule, if any,
            with respect to a particular Award, an Option shall become fully
            vested should the Board of Directors recommend acceptance of a
            take-over bid or issue-bid for Shares of the Company.


                                       9

(10)        OPTION EXERCISE. Options shall be exercised by the delivery of
            written notice to the Company, in such form and to be filed in such
            manner as the Committee shall in its sole discretion prescribe, not
            later than 5:00 p.m., Toronto time, on the last day on which the
            Option may be exercised. Any written notice of the exercise of an
            Option shall set forth the number of Shares with respect to which
            the Option is to be exercised, shall include any statement or
            representation required by the applicable Award Agreement, and shall
            be accompanied by paying in full the purchase price for the Shares.

(11)        REGISTRATION OF OPTION SHARES. The Options shall not be exercisable
            unless the purchase of the Shares is pursuant to an applicable
            effective registration statement under the Securities Act of 1933,
            as amended, or unless, in the opinion of counsel to the Company, the
            proposed purchase of the Shares would be exempt from the
            registration requirements of the Securities Act of 1933, as amended,
            and from the registration or qualification requirements of
            applicable state securities laws.

SECTION 8   CHANGE OF CONTROL.

(1)         For purposes of this Plan, a "Change of Control" shall be deemed to
            have taken place if the shareholders of the Company approve a
            definitive agreement for (i) the merger or other business
            combination of the Company with or into another corporation or
            entity pursuant to which the shareholders of the Company do not own,
            immediately after the transaction, more than 50% of the voting power
            of the corporation or entity that survives the merger or business
            combination, or (ii) the sale, exchange or other disposition of all
            or substantially all of the assets of the Company.

(2)         In the event of a Change of Control, the Committee may, in its
            discretion, determine that all outstanding Options granted under
            this Plan shall become exercisable in full whether or not otherwise
            exercisable at such time, and any such Option shall remain
            exercisable in full thereafter until it expires pursuant to its
            terms.

SECTION 9   AMENDMENT AND TERMINATION.

Except to the extent prohibited by applicable law and unless otherwise expressly
provided in an Award Agreement or in this Plan:

            (a)         AMENDMENTS TO THIS PLAN. The Board may amend, alter,
                        suspend, discontinue, or terminate this Plan at any time
                        without the consent of any shareholder, Participant,
                        other holder or beneficiary of an Award, or other
                        person; provided that notwithstanding any other
                        provision of this Plan or any Award Agreement, no such
                        amendment, alteration, suspension, discontinuation, or
                        termination shall be made without shareholder approval
                        if such approval is necessary to comply with, or to
                        obtain exemptive relief under, any tax or regulatory
                        requirement that the Board deems desirable to comply
                        with;

            (b)         AMENDMENTS TO AWARDS. The Committee may waive any
                        conditions or rights under, amend any terms of, or
                        accelerate or alter, any Award granted hereunder,
                        prospectively or retroactively, without the consent of
                        any relevant Participant or holder or beneficiary of an
                        Award, provided that such action does not (i) materially
                        impair the rights of any Participant or holder or
                        beneficiary of an Award without such person's consent,
                        or (ii) result in a decrease in the Fair

                                       10

   11


                        Market Value of an Award without such Participant's or
                        holder's or beneficiary's consent;

            (c)         ADJUSTMENTS OF AWARDS UPON CERTAIN ACQUISITIONS. In the
                        event the Company or any Affiliate shall assume
                        outstanding employee awards or the right or obligation
                        to make future employee awards in connection with the
                        acquisition of another business or another corporation
                        or business entity, the Committee may make such
                        adjustments, not inconsistent with the terms of this
                        Plan, in the terms of Awards as it shall deem
                        appropriate in order to achieve reasonable comparability
                        or an equitable relationship between the assumed awards
                        and the Awards as so adjusted;

            (d)         ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN
                        UNUSUAL OR NONRECURRING EVENTS. The Committee is hereby
                        authorized to make adjustments in the terms and
                        conditions of, and the criteria included in, Awards in
                        recognition of unusual or nonrecurring events
                        (including, without limitation, the events described in
                        Section 4(3) hereof) affecting the Company, any
                        Affiliate, or the financial statements of the Company or
                        any Affiliate, or of changes in applicable laws,
                        regulations, or accounting principles, whenever the
                        Committee determines that such adjustments are
                        appropriate in order to prevent dilution or enlargement
                        of the benefits or potential benefits intended to be
                        made available under this Plan; and

            (e)         CANCELLATION. Any provision of this Plan or any Award
                        Agreement to the contrary notwithstanding, the Committee
                        may cause any Award granted hereunder to be cancelled in
                        consideration of a cash payment or alternative Award
                        (equal to the Fair Market Value of the Award to be
                        cancelled) made to the holder of such cancelled Award.

SECTION 10  GENERAL PROVISIONS.

(1)         REPRESENTATIONS; LEGEND. The Committee may require each person
            purchasing Shares pursuant to an Option to represent to and agree
            with the Company in writing that the Participant is acquiring the
            Shares without a view to the distribution thereof. The certificates
            for such Shares may include any legend which the Committee deems
            appropriate to reflect any restrictions on transfer.

(2)         NO RIGHTS TO AWARDS. No Employee, Participant or other person shall
            have any claim to be granted any Award, and there is no obligation
            for uniformity of treatment of Employees, Participants, or holders
            or beneficiaries of Awards. The terms and conditions of Awards need
            not be the same with respect to each recipient.

(3)         WITHHOLDING. A Participant may be required to pay to the Company or
            any Affiliate, and the Company or any Affiliate shall have the right
            and is hereby authorized to withhold from any Award, from any
            payment due or transfer made under any Award or under this Plan or
            from any compensation or other amount owing to a Participant, the
            amount (in cash, Shares, other securities, other Awards or other
            property, as determined by the Committee) of any applicable
            withholding taxes in respect of an Award, its exercise, or any
            payment or transfer under an Award or under this Plan and to take
            such other action

                                       11

   12


            as may be necessary in the opinion of the Company to satisfy all
            obligations for the payment of such taxes. In the case of payments
            of Awards in the form of Shares, at the Committee's discretion, the
            Participant may be required to pay to the Company or an Affiliate
            the amount of any taxes required to be withheld with respect to such
            Shares or, in lieu thereof, the Company or an Affiliate shall have
            the right to retain (or the Participant may be offered the
            opportunity to elect to tender) the number of Shares whose Fair
            Market Value equals the amount required to be withheld. The
            Committee may provide for additional cash payments to holders of
            Awards to defray or offset any tax arising from the grant, vesting,
            exercise or payments of any Award. In the discretion of the
            Committee, the Company may offer loans to Participants to satisfy
            withholding requirements on such terms as the Committee may
            determine, which terms may in the discretion of the Committee be
            non-interest bearing.

(4)         NO LIMIT ON OTHER COMPENSATION ARRANGEMENTS. Nothing contained in
            this Plan shall prevent the Company or any Affiliate from adopting
            or continuing in effect other compensation arrangements, which may
            (but need not) provide for the grant of options, restricted stock
            and other types of security-based awards provided for hereunder
            (subject to shareholder approval if such approval is required), and
            such arrangements may be either generally applicable or applicable
            only in specific cases.

(5)         NO RIGHT TO EMPLOYMENT. The grant of an Award shall not be construed
            as giving a Participant the right to be retained in the employ of,
            or to continue to render services to, the Company or any Affiliate.
            Further, the Company or an Affiliate may at any time dismiss a
            Participant from employment, or otherwise terminate its relationship
            with a Service Provider, free from any liability or any claim under
            this Plan, except to the extent expressly provided otherwise in this
            Plan or in any Award Agreement.

(6)         NO RIGHTS AS SHAREHOLDER. Subject to the provisions of the
            applicable Award Agreement, no Participant or holder or beneficiary
            of any Award shall have any rights as a shareholder with respect to
            any Shares to be distributed under this Plan until he or she has
            become the holder of such Shares.

(7)         GOVERNING LAW. The validity, construction, and effect of this Plan
            and any rules and regulations relating to this Plan and any Award
            Agreement shall be determined in accordance with the laws of the
            State of Delaware and applicable United States law; provided,
            however, that, to the extent Canadian federal or Ontario provincial
            law is applicable to any aspect of this Plan, such law shall control
            to the extent that it does not conflict with application of any
            securities laws or tax laws of the United States upon the grant or
            exercise of an Award.

(8)         SEVERABILITY. If any provision of this Plan or any Award is or
            becomes or is deemed to be invalid, illegal, or unenforceable in any
            jurisdiction or as to any person or Award, or would disqualify this
            Plan or any Award under any law deemed applicable by the Committee,
            such provision shall be construed or deemed amended to conform to
            applicable laws, or if it cannot be construed or deemed amended
            without, in the determination of the Committee, materially altering
            the intent of this Plan or the Award, such provision shall be
            stricken as to such jurisdiction, person or Award and the remainder
            of this Plan and any such Award shall remain in full force and
            effect.

                                       12

   13




(9)         OTHER LAWS. The Committee may refuse to issue or transfer any Shares
            or other consideration under an Award if it determines that the
            issuance or transfer of such Shares or such other consideration
            might violate any applicable law or regulation, and any payment
            tendered to the Company by a Participant, other holder or
            beneficiary in connection with the exercise of such Award shall be
            promptly refunded to the relevant Participant, holder or
            beneficiary. Without limiting the generality of the foregoing, no
            Award granted hereunder shall be construed as an offer to sell
            securities of the Company, and no such offer shall be outstanding,
            unless and until the Committee has determined that any such offer,
            if made, would be in compliance with all applicable requirements of
            Federal securities laws.

(10)        NO TRUST OR FUND CREATED. Neither this Plan nor any Award shall
            create or be construed to create a trust or separate fund of any
            kind or a fiduciary relationship between the Company or any
            Affiliate and a Participant or any other person. To the extent that
            any person acquires a right to receive payments from the Company or
            any Affiliate pursuant to an Award, such right shall be no greater
            than the right of any unsecured general creditor of the Company or
            any Affiliate.

(11)        NO FRACTIONAL SHARES. No fractional Shares shall be issued or
            delivered pursuant to this Plan or any Award, and the Committee
            shall determine whether cash, other securities, or other property
            shall be paid or transferred in lieu of any fractional Shares or
            whether such fractional Shares or any rights thereto shall be
            cancelled, terminated, or otherwise eliminated.

(12)        HEADINGS. Headings are given to the Sections and subsections of this
            Plan solely as a convenience to facilitate reference. Such headings
            shall not be deemed in any way material or relevant to the
            construction or interpretation of this Plan or any provision
            thereof.

(13)        BROKERAGE ARRANGEMENTS. The Committee, in its discretion, may enter
            into arrangements with one or more banks, brokerages or other
            financial institutions to facilitate the disposition of Shares
            acquired upon exercise of Options, including, without limitation,
            the sale of the Shares acquired upon such exercise.

(14)        INDEMNIFICATION. Any person who was or is a party or is threatened
            to be made a party to any threatened, pending or completed action,
            suit or proceeding, whether civil, criminal, administrative or
            investigative (including any action or suit by or in the right of
            the Company to procure a judgment in its favor) by reason of the
            fact that he or she is or was a member of the Committee, shall be
            indemnified by the Company, if, as and to the extent authorized by
            the laws of the Provence of Ontario, against expenses (including
            attorneys' fees), judgments, fines and amounts paid in settlement
            (if the terms of such settlement have been consented to by the
            Company) actually and reasonably incurred by him or her in
            connection with the defense or settlement of such action, suit or
            proceeding. The indemnification expressly provided by statute in a
            specific case shall not be deemed exclusive of any other rights to
            which any person indemnified may be entitled under any lawful
            agreement, vote of shareholders or disinterested directors or
            otherwise, both as to action in his or her official capacity and as
            to action in any other capacity while holding such office, and shall
            continue as to a person who has ceased to be a director, officer,
            employee or agent and shall inure to the benefit of the heirs,
            personal representatives and

                                       13

   14


            administrators of such a person. No right of indemnification under
            the provisions set forth herein shall be available to or enforceable
            by any such person unless, within sixty (60) days after institution
            of any such action or proceeding, such person shall have offered the
            Company, in writing, notice of and the opportunity to handle and
            defend same at its own expense unless the Company shall have waived
            the requirement to provide such written notice and offer.

SECTION 11  EFFECTIVE DATE OF THIS PLAN.

This Plan shall be effective on January 1, 1999 (the "EFFECTIVE DATE");
provided, however, that if this Plan is not approved by the shareholders of the
Company within the period ending twelve (12) months after the Effective Date,
none of the Options granted hereunder shall constitute Incentive Stock Options.

SECTION 12  TERM OF THIS PLAN.

No Award shall be granted under this Plan after March 27, 2005; provided,
however, that any Award theretofore granted may, and the authority of the Board
or the Committee to amend, alter, adjust, suspend, discontinue, or terminate any
such Award or to waive any conditions or rights under any such Award shall,
extend beyond such date.

The Stock Options, granted under the 1995 Plan, entitling holders to purchase an
aggregate of 606,000 Shares as of April 12, 2001, shall continue to be governed

respect to which Awards may be granted under this Plan. Subject to the limits
set in Section 4(1) of this Plan, as may be amended and approved by Shareholders
from time to time; additional Shares, currently reserved for the 1995 Plan,
shall also be Shares with respect to which Awards may be granted. Upon expiry of
the final Stock Option under the 1995 Plan on or before January 15, 2005, the
latest expiry date of the Stock Options currently outstanding under the 1995
Plan, the 1995 Plan shall terminate and Schedule "A" shall be deleted from this
Plan.

                                STOCK OPTION PLAN

1.       PURPOSE

The Zemex Corporation 1995 Stock Option Plan (the "Plan") provides for the grant
of Stock Options and Supplemental Bonuses to Employees, Consultants and/or
Eligible Nonemployee Directors of Zemex Corporation (the "Corporation"), and
such of its subsidiaries (as defined in Section 424(f) of the Internal Revenue
Code of 1986, as amended (the "Code") as the Board of Directors of the

Subsidiaries"), in order to advance the interests of the Corporation and its
Participating Subsidiaries through the motivation, attraction and retention of
their respective Employees, Consultants and/or Eligible Nonemployee Directors.

2.       INCENTIVE STOCK OPTIONS AND NON-INCENTIVE STOCK OPTIONS

The Stock Options granted under the Plan may be either:

(a)      Incentive Stock Options ("ISOs") which are intended to be "Incentive
         Stock Options" as that term is defined in Section 422 of the Code; or

(b)      Nonstatutory Stock Options ("NSOs") which are intended to be options
         that do not qualify as "Incentive Stock Options" under Section 422 of
         the Code.

All Stock Options shall be NSOs unless the Option Agreement clearly designates
the Stock Options granted thereunder, or a specified portion thereof, as ISOs.
Subject to the other provisions of the Plan, a Participant may receive ISOs and
NSOs at the same time, provided that the ISOs and NSOs are clearly designated as
such.

Except as otherwise expressly provided herein, all of the provisions and
requirements of the Plan relating to Stock Options shall apply to ISOs and NSOs.

authority to interpret and construe any provision of the Plan and any Stock
Option or Supplemental Bonus granted thereunder, and to adopt such rules and
regulations for administering the Plan as it may deem necessary in order to
comply with the requirements of the Code, in order that Stock Options that are
intended to be ISOs will be classified as incentive stock options under the
Code, or in order to conform to any regulation or to any change in any law or
regulation applicable thereto. The Committee may delegate any of


                                       15

Stock Options, to determine whether the Supplemental Bonuses, if any, payable to
a Participant shall be paid in cash, in shares of Common Stock or a combination
thereof, or to interpret and construe the Plan. If the Board is composed
entirely of Disinterested Persons, the Board may reserve to itself any of the
authority granted to the Committee as set forth herein, and it may perform and
discharge all of the functions and responsibilities of the Committee at any time
that a duly constituted Committee is not appointed and serving. All references
in the Plan to the "Committee" shall be deemed to refer to the Board whenever
the Board is discharging the powers and responsibilities of the Committee, and
to any special committee appointed by the Board to administer particular aspects
of the Plan.

3.2      ACTIONS OF COMMITTEE. Meetings of the Committee shall be held at such
times and places as shall be determined by the Committee. A majority of the
members of the Committee shall constitute a quorum for the transaction of
business, and the vote of a majority of those members present at any meeting at
which a quorum is present shall decide any question brought before that meeting.
In addition, the Committee may take any action otherwise proper under the Plan
without a meeting by the unanimous written consent of its members. No member of
the Committee shall be liable for any act or omission of any other member of the
Committee or for any act, determination or omission made in good faith on his
own part, including but not limited to the exercise of any power or discretion
given to him under the Plan, with respect to the Plan or any award thereunder.

Committee in good faith (including determinations of Fair Market Value) shall be
final and binding upon all Participants, the Corporation and all other
interested persons. No member of the Committee shall be personally liable for
any action, determination or interpretation made in good faith with respect to
the Plan, and all members of the Committee shall, in addition to their rights as
directors, be fully protected by the Corporation with respect to any such
action, determination or interpretation.

6.       SHARES OF COMMON STOCK SUBJECT TO THE PLAN

6.1      MAXIMUM NUMBER.

(a)      The stock subject to Stock Options that may be granted under the Plan
         shall be shares of the Common Stock as constituted on the date the Plan
         becomes effective, and any other shares into which such Common Stock
         shall thereafter be changed by reason of a stock dividend,
         recapitalization, merger, consolidation, amalgamation, split-up,
         combination, reverse stock split, exchange of shares, rights offering,
         or the like as determined by the Committee in its discretion pursuant
         to the provisions of Section 6.2 of the Plan. The maximum number of
         shares of Common Stock with respect to which Stock Options may be
         granted under the Plan shall not exceed in the aggregate ten percent of
         the number of shares of Common Stock outstanding from time to time;
         provided, however, that

         (i)      shares of Common Stock issued pursuant to the Plan or any
                  other employee benefit plan or arrangement shall not be
                  included in the number of shares outstanding for purposes of
                  calculating under this sentence the number of shares as to
                  which Stock Options may be granted under the Plan;

         (ii)     any increase in the number of shares of Common Stock
                  outstanding in connection with an event which results in an
                  adjustment pursuant to Section 6.2 shall not be included in
                  the number of shares outstanding for purposes of calculating
                  under this sentence the number of shares as to which Stock
                  Options may be granted under the Plan;

         (iii)    any reduction in the number of outstanding shares of Common
                  Stock shall not affect any Stock Options granted under the
                  Plan prior to such reduction;

         (iv)     the class and aggregate number of shares of Common Stock which
                  may be subject to Stock Options granted under the Plan shall
                  be subject to adjustment in accordance with the provisions of
                  Section 6.2 of the Plan; and

         (v)      the Committee may grant Stock Options the exercisability of
                  which is conditioned upon an increase in the number of shares
                  of Common Stock outstanding from time to time and, until such
                  condition is satisfied, such Stock Options shall not be taken
                  into account in computing the number of shares of Common Stock
                  with respect to which Stock Options have been granted under
                  the Plan.

(b)      In the event that any outstanding Stock Option for any reason shall
         expire or is terminated or cancelled, the shares of Common Stock
         allocable to the unexercised portion of such Stock Option may again be
         subject to a Stock Option under the Plan. There shall be reserved and
         kept available, free from preemptive rights, out of the Corporation's
         authorized but unissued shares of Common Stock or its authorized and
         issued Common Stock held in its treasury, or any combination thereof,
         for sale under the Plan a number of shares of Common Stock equal to the
         maximum number of shares that may be purchased pursuant to Stock
         Options granted or that may be granted under the Plan.

                                       18

   19




(c)      The Committee may, with the consent of the holder of any Stock Option
         granted under the Plan, cancel such Stock Option and grant a new Stock
         Option in substitution therefor, provided that the Stock Option as so
         substituted shall satisfy all of the requirements of the Plan as of the
         date such new Stock Option is granted.

(d)      The aggregate Fair Market Value (determined as of the time the ISO is
         granted) if the Common Stock as to which all ISOs granted to an
         Employee may first become exercisable in a particular calendar year may
         not exceed $100,000.

(e)      No Stock Option may be granted under the Plan after March 27, 2005.

6.2      CAPITAL CHANGES. In the event any changes are made to the shares of
Common Stock, (whether by reason of merger, consolidation, reorganization,
recapitalization, stock dividend in excess of ten percent (10%) at any single
time, stock split, combination of shares, exchange of shares, change in
corporate structure or otherwise), appropriate adjustments shall be made in: (i)
the number of shares of Common Stock theretofore made subject to Stock Options,
and in the purchase price of said shares and (ii) the aggregate number of shares
which may be made subject to Stock Options. If any of the foregoing adjustments
shall result in a fractional share, the fraction shall be disregarded, and the
Corporation shall have no obligation to make any cash or other payment with
respect to such a fractional share.

7.       EXERCISE OF STOCK OPTIONS

7.1      TIME OF EXERCISE.

(a)      Subject to the provisions of the Plan, including without limitation
         Section 7.5, the Committee, in its discretion, shall determine the time
         when a Stock Option, or a portion of a Stock Option, shall become
         exercisable, and the time when a stock Option, or a portion of a Stock
         Option, shall expire. Such time or times shall be set forth in the
         Option Agreement evidencing such Stock Option. Subject to the
         provisions of Article V, an ISO shall expire, to the extent not
         exercised, no later than the tenth anniversary of the date on which it
         was granted, and an NSO shall expire, to the extent not exercised, no
         later than 10 years after the date on which it was granted. No Stock
         Option may be exercised prior to one year from the date of grant. The
         Committee may accelerate the vesting of any Participant's Stock Option
         by giving written notice to the Participant. Upon receipt of such
         notice, the Participant and the Corporation shall amend the Option
         Agreement to reflect the new vesting schedule. The acceleration of the
         exercise period of a Stock Option shall not affect the expiration date
         of that Stock Option.

(b)      Stock Options shall be exercised by the delivery of written notice to
         the Corporation, in such form and to be filed in such manner as the
         Committee shall in its sole discretion prescribe, not later than 5:00
         p.m., New York City time, on the last day on which such Stock Option
         may be exercised. Any written notice of the exercise of a Stock Option
         shall set forth the number of shares of Common Stock with respect to
         which the Stock Option is to be exercised, shall include any statement
         or representation required by the applicable Option Agreement, sand
         shall be accompanied by paying in full of the purchase price of such
         shares of Common Stock.

                                       19

   20


7.2      EXCHANGE OF OUTSTANDING STOCK. Each Stock Option shall provide that the
purchase price of the shares of Common Stock as to which a Stock Option shall be
exercised shall be paid to the Corporation at the time of exercise either in
cash or in such other consideration as the Committee in its discretion deems
appropriate, including, but not limited to, shares of Common Stock already owned
by the optionee having total Fair Market Value, as determined by the Committee,
equal to the purchase price, or a combination of cash and Common Stock having a
total Fair Market Value, as so determined, equal to the amount of the purchase
price not paid in cash. As soon as practicable after receipt of such payment,
the Corporation shall;, subject to the provisions of Sections 7.4 and 14 of the
Plan, deliver, to the grantee a certificate or certificates for the shares of
Common Stock so purchased.

7.3      USE OF PROMISSORY NOTE; EXERCISE LOANS. The Committee may, in its sole
discretion, impose terms and conditions, including condition relating to the
manner and timing of payments, on the exercise of Stock Options. Such terms and
conditions may include, but are not limited to permitting a Participant to
deliver to the Corporation his promissory note as full or partial payment of the
exercise of a Stock Option; provided that, with respect to any promissory note
given a payment or partial payment for the exercise of an ISO, all terms of such
note shall be determined at the time a Stock Option is granted and set forth in
the Option Agreement. The Committee, in its sole discretion, may authorize the
Corporation to make a loan to a Participant in connection with the exercise of
Stock Options, or authorize the Corporation to arrange or guaranty loans to a
Participant by a third party.

7.4      STOCK RESTRICTION AGREEMENT. The Committee may provide that shares of
Common Stock issuable upon the exercise of a Stock Option shall, under certain
conditions, be subject to restrictions whereby the Corporation has a right of
first refusal with respect to such shares or a right or obligation to repurchase
all or a portion of such shares, which restrictions may survive a Participant's
term of employment with the Corporation. The acceleration of time or times at
which a Stock Option becomes exercisable may be conditioned upon the
Participant's agreement to such restrictions.

7.5      TERMINATION OF EMPLOYMENT BEFORE EXERCISE.

(a)      If at any time prior to the expiration of a Stock Option granted to an
         Employee of the Corporation or a Participating Subsidiary, such
         optionee shall not be an Employee of the Corporation or a Participating
         Subsidiary, then:

         (i)      if such employment is terminated by retirement of or after the
                  earliest date on which an immediate retirement benefit is
                  payable in accordance with the terms of a tax-qualified
                  retirement plan of the Corporation or a Participating
                  Subsidiary or by reason of disability as determined by the
                  Committee in its discretion, such Stock Option may be
                  exercised, to the same extent it was exercisable at the date
                  of such termination of employment, during the three-month
                  period following the date of such termination (but in no event
                  after the expiration of such Stock Option as provided in the
                  Option Agreement and, in the case of an ISO, in no event
                  beyond ten years from the date of grant of the ISO);

         (ii)     if such employment is terminated by death, such Stock Option
                  may be exercised by the person or persons entitled to do so
                  under the optionee's will or, if the optionee shall have
                  failed to make testamentary disposition of such Stock Option
                  or shall have died intestate, by the optionee's legal
                  representative, to the same extent is was exercisable on the
                  date of

                                       20

   21


                  such optionee's death, during the twelve-month period
                  following the date of such optionee's death (but in no event
                  after the expiration of such Stock Option as provided in the
                  Option Agreement and, in the case of an ISO, in no event
                  beyond ten years from the date of grant of the ISO): and

         (iii)    if such employment is terminated voluntarily or involuntary
                  for any reason other than retirement, disability or death,
                  such Stock Option shall terminate and cease to be exercisable
                  immediately upon such termination of employment; provided,
                  however, that if the Board of Directors shall determine that

                  (A)      due to special and unusual circumstances, the Stock
                           Option should be permitted to be exercised after
                           termination of employment; and

                  (B)      taking in account the optionee's record of service
                           and performance during his employment and all of the
                           circumstances surrounding the termination of
                           employment, the optionee has not acted in a manner
                           detrimental to the Corporation or Participating
                           Subsidiary by which the optionee was employed,

                  such Stock Option may be exercised during the three-month
                  period following such termination of employment (but in no
                  event following the expiration of such Stock Option as
                  provided in the Option Agreement and, in the case of an ISO,
                  in no event beyond ten years from the date of grant of the
                  ISO) with respect to a number of shares as the Board of
                  Directors shall approve, but in no event with respect to a
                  number of shares of Common Stock greater than the number of
                  shares as to which such Stock Option remains unexercised at
                  the date of termination of the optionee's employment.

         (iv)     for purposes of the foregoing, if the 10% ownership
                  limitations of Article V apply to the Participant, five years
                  shall be substituted for ten years each place it appears in
                  the preceding paragraphs.

(b)      If at any time prior to the expiration of a Stock Option granted to a
         person who at the time of grant is a Consultant or an Eligible
         Nonemployee Director, such optionee shall not be a Consultant or a
         director, as the case may be, then such Stock Option may be exercised,
         to the extent it was exercisable on the date the optionee ceased to be
         a Consultant or a director, as the case may be, during the seven-month
         period following the termination of such consultancy or directorship,
         as the case may be (but in no event after the expiration of such Stock
         Option as provided in the Option Agreement); provided, however, that
         the Corporation may wave the Stock Option termination date otherwise
         applicable under this paragraph (b) if the optionee will become an
         Employee following the termination of such consultancy or directorship.

(c)      Notwithstanding the provisions of this Section 7.5 or any other
         provision of the Plan, with respect to any Stock Options granted to an
         Employee in connection with the commencement of employment as an
         Employee, the Committee may provide for terms as to retirement,
         disability, death or other termination of employment which are
         different from the terms provided in paragraph (a) of this Section 11
         if such different terms are set forth in a written employment agreement
         with such Employee, which agreement shall have been approved by the
         Board, or are otherwise provided by the Committee, subject to approval
         by the Board.

                                       21

   22


         Notwithstanding the foregoing, no Stock Options which are ISOs may be
         granted pursuant to this subparagraph.

(d)      Whether authorized leave of absence or absence on military service
         shall constitute severance of the employment relationship between the
         Corporation or a Participating Subsidiary and the optionee shall be
         determined by the Committee at the time thereof. Notwithstanding the
         foregoing, in the case of Stock Options which are ISOs , if the period
         of leave exceeds 90 days, unless the individual's right to reemployment
         is guaranteed by statue or contract, the employment relationship will
         be deemed to have terminated on the 91st day of such leave.

(e)      If an optionee's status with the Corporation or a Participating
         Subsidiary changes, but such optionee continues as a Consultant to the
         Corporation, then the Committee in its discretion may elect that the
         Stock Option previously granted shall continue in full force and effect
         so long as such Stock Option is an NSO. The Committee shall be
         permitted in its discretion, to grant NSOs, which provide that the
         Stock Option shall continue in full force and effect if the optionee's
         status with the Corporation or a Participating Subsidiary changes, but
         such person continues as a Consultant to the Corporation.

7.6      DISPOSITION OF FORFEITED STOCK OPTIONS. If the Stock Option is not
exercised during the applicable period, it shall be deemed to have been
forfeited and of no further force or effect. Any shares of Common Stock subject
to Stock Options forfeited by a Participant shall not thereafter be eligible for
purchase by the Participant but may be made subject to Stock Options granted to
other Participants.

7.7      GRANT OF SUPPLEMENTAL BONUSES. The Committee, either at the time of
grant or at any time prior to exercise of any Stock Option, may provide for a
Supplemental Bonus from the Corporation or Participating Subsidiary in
connection with a specified number of shares of Common Stock then purchasable,
or which may become purchasable, under a Stock Option. Such Supplemental Bonus
shall be payable upon the exercise of the Stock Option with regard to which such
Supplemental Bonus was granted. A Supplemental Bonus shall not exceed the amount
necessary to reimburse the Participant for the income tax liability incurred by
him upon the exercise of the Stock Option calculated using the maximum combined
federal and applicable state income tax rates then in effect and taking into
account the tax liability arising from the Participant's receipt of the
Supplemental Bonus. Payment of a Participant's Supplemental Bonus shall be made
on or before the 90th day after the exercise of the Stock Option with regard to
which such Supplemental Bonus was granted. The Committee may, in its discretion,
elect to pay any part or all of the Supplemental Bonus in: (i) cash; (ii) shares
of Common Stock; or (iii) any combination of cash and shares of Common Stock.
The Committee's election pursuant to this Section 7.7 shall be made by giving
written notice to the Participant within 90-day payment period, which notice
shall specify the portion which the committee elects to pay in cash, shares or
Common Stock or a combination thereof. In the event any portion is to be paid in
shares of Common Stock, the number of shares to be delivered shall be determined
by dividing the amount which the Committee elects to pay in shares of Common
Stock by the Fair Market Value of the share of Common Stock on the date of
exercise of the Stock Option with regard to which the Supplemental Bonus was
granted. Any fractional share resulting from any such calculation shall be
disregarded. Said shares, together with any cash payable to the Participant,
shall be delivered within said 90-day payment period. Shares of Common Stock
issued pursuant to this Section 7.7 shall not be deemed to have been issued upon
the exercise of a Stock Option for purposes of the limitations imposed by
Section 6.1 of the Plan.

                                       22

   23


8.       NO CONTRACT OF EMPLOYMENT

Nothing in this Plan shall confer upon the Participant the right to continue in
the employ of the Corporation, or any Participating Subsidiary, nor shall it
interfere in any way with the right of the Corporation, or any such
Participating Subsidiary, to discharge the Participant at any time for any
reason whatsoever, with or without cause. Nothing in this Article VIII shall
affect any rights or obligations of the Corporation or any Participant under any
written contract of employment.

9.       NO RIGHTS AS A STOCKHOLDER

A Participant shall have no rights as a stockholder with respect to any shares
of Common Stock subject to a Stock Option. Except as provided in Section 6.2, no
adjustment shall be made in the number of shares of Common Stock issued to a
Participant, or in any other rights of the Participant upon exercise of a Stock
Option by reason of any dividend, distribution or other right granted to
stockholders for which the record date is prior to the date of exercise of the
Participant's Stock Option.

10.      ASSIGNABILITY

No Stock Option or Supplemental Bonus right granted under this Plan, nor any
other rights acquired by a Participant under this Plan, shall be assignable or
transferable by a Participant, other than by will or the laws of descent and
distribution or, in the case of an NSO, pursuant to a qualified domestic
relations order as defined by the Code, Title I of the Employee Retirement
Income Security Act, or the rules thereunder. Notwithstanding the preceding
sentence, the Committee may, in its sole discretion, permit the assignment or
transfer of an NSO by a Participant other than an officer or director, and the
exercise thereof by a person other than such Participant, on such terms and
conditions as the Committee in its sole discretion may determine. Any such terms
shall be determine at the time the NSO is granted, and shall be set forth in the
Option Agreement. In the event of his death, the Stock Option or Supplemental
Bonus rights which are exercisable pursuant to the terms of the Plan may be
exercised by the Personal Representative of the Participant's estate or. Or if
no Personal Representative has been appointed, by the successor or successors in
interest determined under the Participant's will or under the applicable laws of
descent and distribution.

11.      MERGER OR LIQUIDATION OF THE CORPORATION

(a)      The existence of outstanding Stock Options shall not affect in any way
         the right or power of the Corporation or its stockholders to make or
         authorize any or all adjustments, recapitalizations, reorganizations or
         other changes in the Corporation's capital structure or its business,
         or any merger or consolidation of the Corporation, or any issue of
         bonds, debentures, preferred or prior preference stock ahead of or
         affecting the Common Stock or the rights thereof, or the dissolution or
         liquidation of the Corporation, or any sale or transfer of all or any
         part of its assets or business, or any other corporate act or
         proceeding, whether of a similar character or otherwise.

(b)      If the Corporation is to be merged or amalgamated with or into another
         corporation, or if the Corporation is to be reorganized, liquidated or
         dissolved, or if all or substantially all of the assets or all of the
         outstanding Common Stock of the Corporation is to be acquired by
         another corporation (individually, a "Transaction" and collectively,
         the "Transactions"), in


                                       23

   24


         lieu of any outstanding Stock Options remaining exercisable for shares
         of Common Stock following the effective time of the Transaction, the
         Board of the Corporation may make appropriate provision, by resolution
         or by the terms of the Transaction as set out in a written agreement
         relating to the Transaction which has been approved by the Board and
         duly executed and delivered on behalf of the Corporation to the other
         party or parties to the Transaction, or otherwise, for any of the
         following: (1) after the Transaction, an optionee holding an
         outstanding Stock Option shall be entitled upon exercise of such Stock
         Option to receive (subject to any required action by stockholders) in
         lieu of the number and class of shares of stock or other securities to
         which such Stock Option would have been entitled pursuant to the terms
         of the Transaction if, immediately prior to the effective time of the
         Transaction, such holder had been the holder of record of the number
         and class of shares equal to the number and class of shares (as
         constituted prior to the Transaction) as to which such Stock Option
         shall be so exercised; or (2) an outstanding Stock Option (other than
         any Stock Option held by an optionee who is subject to Section 16(b) of
         the Securities Exchange Act of 1934, as amended, which Stock Options
         will not have been granted more than six months prior to the effective
         time of the Transaction) may be cancelled by the Committee as of the
         effective time of the Transaction provided that (x) notice of such
         cancellation shall be given to the holder of the Stock Option and (y)
         the Committee shall have waived any limitations on exercise imposed
         pursuant to provisions of the Plan or the Options Agreement with
         respect to such Stock Option and the holder of such Stock Option shall
         have the right to exercise such Stock Option in full (without regard to
         any limitations on exercise imposed pursuant to provisions of the Plan
         or the Option Agreement) during a 25-day period preceding the effective
         time of the Transaction; or (3) at the effective time of the
         Transaction the holder of an outstanding Stock Option shall be entitled
         to receive cash with respect to each share as to which the Stock Option
         remains unexercised at the effective time of the Transaction (without
         regard to any limitations on exercise imposed pursuant to provisions of
         the Plan or the Option Agreement) considering having a Fair Market
         Value, as determined by the Committee, equal to the amount by which the
         value (as determined by the Committee in its discretion) of the
         consideration to be paid per outstanding share of Common Stock pursuant
         to the terms of the Transaction exceeds the per share exercise price of
         the shares of Common Stock subject to such Stock Options; or (4) there
         shall be substituted for a Stock Option outstanding at the effective
         time of the Transaction a stock option to purchase appropriate stock of
         the Corporation or stock of the surviving consolidated or continuing
         corporation in such Transaction or an affiliate of the Corporation or
         such corporation, provided that the excess of the aggregate Fair Market
         Value of the shares subject to the substitute stock option immediately
         after such substitution over the aggregate purchase price of such
         shares pursuant to such pursuant to such substitute stock option is
         approximately equal to the excess of the Fair Market Value of the
         shares of Common Stock subject to such Stock Option immediately before
         such substitution over the aggregate purchase price of such shares of
         Common Stock pursuant to such Stock Option. In connection with a
         particular Transaction, the Committee may in its discretion make
         provision of one of the preceding alternatives for all Stock Options or
         for different of the preceding alternatives for different Stock
         Options, including different Stock Options held by the same optionee.

(c)      Except as hereinbefore expressly provided or as provided by the
         Committee in its discretion in any particular Stock Option, the issue
         by the Corporation of shares of stock of any class, or securities
         convertible into shares of stock of any class, for cash or property, or
         for labor or services either upon the exercise of rights or warrants to
         subscribe therefor, or upon

                                       24

   25


         conversion of shares or obligations of the Corporation convertible into
         such shares or other securities, shall not affect, and no adjustment by
         reason thereof shall be made with respect to, the number, class or
         price of shares of Stock then subject to outstanding Stock Options.

12.      AMENDMENT

The Board may from time to time alter, amend, suspend or discontinue the Plan,
including, where applicable, any modifications or amendments as it shall deem
advisable in order that ISOs will be classified as incentive stock options under
the Code, or in order to conform to any regulation or to any change in any law
or regulation applicable thereto; provided, however, that no such actions shall
adversely affect the rights and obligations with respect to Stock Options at any
time outstanding under the Plan; and provided further that no such action shall,
without the approval of the stockholders of the Corporation, (i) increase the
maximum number of shares of Common Stock that may be made subject to Stock
Options (unless necessary to effect the adjustments required by Section 6.2),
(ii) materially increase the benefits accruing to Participants under the Plan,
or (iii) materially modify the requirements as to eligibility for participation
in the Plan.

13.      REGISTRATION OF OPTIONED SHARES

The Stock Options shall not be exercisable unless the purchase of such optioned
