          by Lender to perfect and continue Lender's security interest in the
          Collateral. Upon request of Lender, Grantor will deliver to Lender any

          and Grantor will note Lender's interest upon any and all chattel paper
          if not delivered to Lender for possession by Lender. Grantor hereby

          security interest granted in this Agreement. Lender may at any time,
          and without further authorization from Grantor, file a carbon,
          photographic or other reproduction of any financing statement or of
          this Agreement for use as a financing statement. Grantor will

          Grantor. THIS IS A CONTINUING SECURITY AGREEMENT AND WILL CONTINUE IN
          EFFECT EVEN THOUGH ALL OR ANY PART OF THE INDEBTEDNESS IS PAID IN FULL
          AND EVEN THOUGH FOR A PERIOD OF TIME GRANTOR MAY NOT BE INDEBTED TO
          LENDER.

          ENFORCEABILITY OF COLLATERAL. To the extent the Collateral consists of
          accounts, contract rights, chattel paper, or general intangibles, the
          Collateral is enforceable in accordance with its terms,

                                        2

                          COMMERCIAL SECURITY AGREEMENT
                                    CONTINUED

          is genuine, and complies with applicable laws concerning content and
          manner of preparation and execution, and all persons appearing to be
          obligated on the Collateral have authority and capacity to contract
          and are in fact obligated as they appear to be on the Collateral.

          LOCATION OF THE COLLATERAL. Grantor, upon request of Lender, will
          deliver to Lender in form satisfactory to Lender a schedule of real
          properties and Collateral locations relating to Grantor's operations,
          including without limitation the following: (a) all real property
          owned or being purchased by Grantor; (b) all real property being
          rented or leased by Grantor; (c) all storage facilities owned, rented,
          leased, or being used by Grantor; and (d) all other properties where
          Collateral is or may be located. Except in the ordinary course of its
          business, Grantor shall not remove the Collateral from as existing
          locations without the prior written consent of Lender.

          REMOVAL OF COLLATERAL. Grantor shall keep the Collateral (or to the
          extent the Collateral consists of intangible property such as
          accounts, the records concerning the Collateral) at Grantor's address
          shown above, or at such other locations as are acceptable to Lender.
          Except in the ordinary course of its business, including the sales of
          inventory, Grantor shall not remove the Collateral from its existing
          locations without the prior written consent of Lender. To the extent
          that the Collateral consists of vehicles, or other titled property,
          Grantor shall not take or permit any action which would require
          application for certificates of title for the vehicles outside the
          Commonwealth of Massachusetts, without the prior written consent of
          Lender.

          TRANSACTIONS INVOLVING COLLATERAL. Except for inventory sold or
          accounts collected in the ordinary course of Grantor's business,
          Grantor shall not sell, offer to sell, or otherwise transfer or
          dispose of the Collateral. VVhile Grantor is not in default under this
          Agreement, Grantor may sell inventory, but only in the ordinary course
          of its business and only to buyers who qualify as a buyer in the
          ordinary course of business. A sale in the ordinary course of
          Grantor's business does not include a transfer in partial or total
          satisfaction of a debt or any bulk sale. Grantor shall not pledge,
          mortgage, encumber or otherwise permit the Collateral to be subject to
          any lien, security interest, encumbrance, or charge, other than the
          security interest provided for in this Agreement, without the prior
          written consent of Lender. This includes security interests even if
          junior in right to the security interests granted under this
          Agreement. Unless waived by Lender, all proceeds from any disposition
          of the Collateral (for whatever reason) shall be held in trust for
          Lender and shall not be commingled with any other funds; provided
          however, this requirement shall not constitute consent by Lender to
          any sale or other disposition. Upon receipt, Grantor shall immediately
          deliver any such proceeds to Lender.

          TITLE. Grantor represents and warrants to Lender that it holds good
          and marketable tale to the Collateral, free and clear of all liens and
          encumbrances except for the lien of this Agreement. No financing
          statement covering any of the Collateral is on file in any public
          office other than those which reflect the security interest created by
          this Agreement or to which Lender has specifically consented. Grantor
          shall defend Lenders rights in the Collateral against the claims and
          demands of all other persons.

          COLLATERAL SCHEDULES AND LOCATIONS. Insofar as the Collateral consists
          of inventory, Grantor shall deliver to Lender, as often as Lender
          shall require, such lists, descriptions, and designations of such
          Collateral as Lender may require to identify the nature, extent, and
          location of such

                                        3

                          COMMERCIAL SECURITY AGREEMENT
                                    CONTINUED

          Collateral. Such information shall be submitted Grantor and each of
          its subsidiaries or related companies.

          MAINTENANCE AND INSPECTION OF COLLATERAL. Grantor shall maintain all
          tangible Collateral in good condition and repair. Grantor will not
          commit or permit damage to or destruction of the Collateral or any
          part of the Collateral. Lender and its designated representatives and
          agents shall have the right at all reasonable times to examine,
          inspect, and audit the Collateral wherever located. Grantor shall
          immediately notify Lender of all cases involving the return,
          rejection, repossession, loss or damage of or to any Collateral; of
          any request for credit or adjustment or of any other dispute arising
          with respect to the Collateral; and generally of all happenings and
          events affecting the Collateral or the value or the amount of the
          Collateral.

          TAXES, ASSESSMENTS AND LIENS. Grantor will pay when due all taxes,
          assessments and liens upon the Collateral, its use or operation, upon
          this Agreement, upon any promissory note or notes evidencing the
          Indebtedness, or upon any of the other Related Documents. Grantor may
          withhold any such payment or may elect to contest any lien if Grantor
          is in good faith conducting an appropriate proceeding to contest the
          obligation to pay and so long as Lender's interest in the Collateral
          is not jeopardized in Lender's sole opinion. If the Collateral is
          subjected to a lien which is not discharged within fifteen (15) days,
          Grantor shall depose with Lender cash, a sufficient corporate surety
          bond or other security satisfactory to Lender in an amount adequate to
          provide for the discharge of the lien plus any interest, costs,
          attorneys' fees or other charges that could accrue as a result of
          foreclosure or sale of the Collateral. In any contest Grantor shall
          defend itself and Lender and shall satisfy any final adverse judgment
          before enforcement against the Collateral. Grantor shall name Lender
          as an additional obliges under any surety bond furnished in the
          contest proceedings.

          COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS. Grantor shall comply
          promptly with all laws, ordinances, rules and regulations of all
          governmental authorities, now or hereafter in effect, applicable to
          the ownership, production, disposition, or use of the Collateral.
          Grantor may contest in good faith any such law, ordinance or
          regulation and withhold compliance during any proceeding, including
          appropriate appeals, so long as Lender's interest in the Collateral,
          in Lender's opinion, is not jeopardized.

          HAZARDOUS SUBSTANCES. Grantor represents and warrants that the
          Collateral never has been, and never will be so long as this Agreement
          remains a lien on the Collateral, used for the generation,
          manufacture, storage, transportation, treatment, disposal, release or
          threatened release of any hazardous waste or substance, as those terms
          are defined in the Comprehensive Environmental Response, Compensation,
          and Liability Act of 1980, as amended, 42 U.S.C. Section 9601, et seq.
          ("CERCLA"), the Superfund Amendments and Reauthorization Act of 1986,
          Pub. L. No. 99-499 ("SARA"), the Hazardous Materials Transportation
          Act, 49 U.S.C. Section 1801, et seq., the Resource Conservation and
          Recovery Act, 49 U.S.C. Section 6901, et seq., or other applicable
          state or Federal laws, rules, or regulations adopted pursuant to any
          of the foregoing. The terms "hazardous waste" and "hazardous
          substance" shall also include, without limitation, petroleum and
          petroleum by-products or any fraction thereof and asbestos. The
          representations and warranties contained herein are based on Grantors
          due diligence in investigating the Collateral for hazardous wastes and
          substances. Grantor hereby (a) releases and waives any future claims
          against Lender for indemnity or contribution in the event Grantor
          becomes liable for cleanup or other costs

                                    CONTINUED

          under any such laws, and (b) agrees to indemnify and hold harmless
          Lender against any and ail claims and losses resulting from a breach
          of this provision of this Agreement. This obligation to indemnify
          shall survive the payment of the Indebtedness and the satisfaction of
          this Agreement.

          MAINTENANCE OF CASUALLY INSURANCE. Grantor shall procure and maintain
          all risks insurance, including without limitation fire, then and
          liability coverage together with such other insurance as Lender may
          require with respect to the Collateral, in form, amounts, coverages
          and basis reasonably acceptable to Lender and issued by a company or
          companies reasonably acceptable to Lender. Grantor, upon request of
          Lender, will deliver to Lender from time to time the policies or
          certificates of insurance in form satisfactory to Lender, including
          stipulations that coverages will not be cancelled or diminished
          without at least ten (10) days' prior written notice to Lender and not
          including any disclaimer of the insurer's liability for failure to
          give such a notice. Each insurance policy also shall include an
          endorsement providing that coverage in favor of Lender will not be
          impaired in any way by any act, omission or default of Grantor or any
          other person. In connection with all policies covering assets in which
          Lender holds or is offered a security interest, Grantor will provide
          Lender with such loss payable or other endorsements as Lender may
          require. If Grantor at any time fails to obtain or maintain any
          insurance as required under this Agreement, Lender may (but shall not
          be obligated to) obtain such insurance as Lender deems appropriate,
          including if it so chooses "single interest insurance", which will
          cover only Lender's interest in the Collateral.

          APPLICATION OF INSURANCE PROCEEDS. Grantor shall promptly notify
          Lender of any loss or damage to the Collateral. Lender may make proof
          of loss if Grantor fails to do so within fifteen (15) days of the
          casualty. All proceeds of any insurance on the Collateral, including
          accrued proceeds thereon, shall be held by Lender as part of the
          Collateral. If Lender consents to repair or replacement of the damaged
          or destroyed Collateral, Lender shall, upon satisfactory proof of
          expenditure, pay or reimburse Grantor from the proceeds for the
          reasonable cost of repair or restoration. If Lender does not consent
          to repair or replacement of the Collateral, Lender shall retain a
          sufficient amount of the proceeds to pay all of the Indebtedness, and
          shall pay the balance to Grantor. Any proceeds which have not been
          disbursed within six (6) months after their receipt and which Grantor
          has not commuted to the repair or restoration of the Collateral shall
          be used to prepay the Indebtedness.

          INSURANCE RESERVES. Lender may require Grantor to maintain with Lender
          reserves for payment of insurance premiums, which reserves shall be
          created by monthly payments from Grantor of a sum estimated by Lender
          to be sufficient to produce, at least fifteen (15) days before the
          premium due date, amounts at least equal to the insurance premiums to
          be paid. If fifteen (15) days before payment is due, the reserve funds
          are insufficient, Grantor shall upon demand pay any deficiency to
          Lender. The reserve funds shall be held by Lender as a general depose
          and shall constitute a non-interest-bearing account which Lender may
          satisfy by payment of the insurance premiums required to be paid by
          Grantor as they become due. Lender does not hold the reserve funds in
          trust for Grantor, and Lender is not the agent of Grantor for payment
          of the insurance premiums required to be paid by Grantor. The
          responsibility for the payment of premiums shall remain Grantor's sole
          responsibility.

          INSURANCE REPORTS. Grantor, upon request of Lender, shall furnish to
          Lender reports on each existing policy of insurance showing such
          information as Lender may reasonably request including

                                        5

                          COMMERCIAL SECURITY AGREEMENT
                                    CONTINUED

          the following: (a) the name of the insurer; (b) the risks insured; (c)
          the amount of the policy; (d) the property insured; (e) the then
          current value on the basis of which insurance has been obtained and
          the manner of determining that value; and (f) the expiration date of
          the policy. In addition, Grantor shall upon request by Lender (however
          not more often than annually) have an independent appraiser
          satisfactory to Lender determine, as applicable, the cash value or
          replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of the
tangible personal property and beneficial use of all the Collateral and may use
it in any lawful manner not inconsistent with this Agreement or the Related
Documents, provided that Grantor's right to possession and beneficial use shall
not apply to any Collateral where possession of the Collateral by Lender is
required by law to perfect Lender's security interest in such Collateral: If
Lender at any time has possession of any Collateral, whether before or after an
Event of Default, Lender shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral if Lender takes such action for
that purpose as Grantor shall request or as Lender, in Lender's sole discretion,
shall deem appropriate under the circumstances, but failure to honor any request
by Grantor shall not of Itself be deemed to be a failure to exercise reasonable
care. Lender shall not be required to take any steps necessary to preserve any
rights in the Collateral against prior parties, nor to protect, preserve or
maintain any security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral. Lender also may (but shall not be
obligated to) pay all costs for insuring, maintaining and preserving the
Collateral. All such expenditures incurred or paid by Lender for such purposes
will then bear interest at the rate charged under the Note from the date
incurred or paid by Lender to the date of repayment by Grantor. All such
expenses shall become a part of the Indebtedness and, at Lender's option, will
(a) be payable on demand, (b) be added to the balance of the Note and be
apportioned among and be payable with any installment payments to become due
during either (i) the term of any applicable insurance policy or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity. This Agreement also will secure payment
of these amounts. Such right shall be in addition to all other rights and
remedies to which Lender may be entitled upon the occurrence of an Event of
Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

          DEFAULT ON INDEBTEDNESS. Failure of Grantor to make any payment when
          due on the Indebtedness.

          OTHER DEFAULTS. Failure of Grantor to comply with or to perform any
          other term, obligation, covenant or condition contained in this
          Agreement or in any of the Related Documents or in any other agreement
          between Lender and Grantor.

          INSOLVENCY. The dissolution or termination of Grantor's existence as a
          going business, the insolvency of Grantor, the appointment of a
          receiver for any part of Grantor's property, any assignment for the
          benefit of creditors, any type of creditor workout, or the

                          COMMERCIAL SECURITY AGREEMENT
                                    CONTINUED

          CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
          forfeiture proceedings, whether by judicial proceeding, self-help,
          repossession or any other method, by any creditor of Grantor or by any
          governmental agency against the Collateral or any other collateral
          securing the Indebtedness. This includes a garnishment of any of
          Grantor's depose accounts with Lender.

          EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with
          respect to any Guarantor of any of the Indebtedness or such Guarantor
          dies or becomes incompetent.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the Massachusetts Uniform Commercial Code. In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

          ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness,
          including any prepayment penalty which Grantor would be required to
          pay, immediately due and payable, without notice.

          ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender
          all or any portion of the Collateral and any and all certificates of
          tale and other documents relating to the Collateral. Lender may
          require Grantor to assemble the Collateral and make d available to
          Lender at a place to be designated by Lender. Lender also shall have
          full power to enter upon the property of Grantor to take possession of
          and remove the Collateral. If the Collateral contains other goods not
          covered by this Agreement at the time of repossession, Grantor agrees
          Lender may take such other goods, provided that Lender makes
          reasonable efforts to return them to Grantor after repossession.

          SELL THE COLLATERAL. Lender shall have full power to sell, lease,
          transfer, or otherwise deal with the Collateral or proceeds thereof in
          as own name or that of Grantor. Lender may sell the Collateral at
          public auction or private sale. Unless the Collateral threatens to
          decline speedily in value or is of a type customarily sold on a
          recognized market, Lender will give Grantor reasonable notice of the
          time after which any private sale or any other intended disposition of
          the Collateral is to be made. The requirements of reasonable notice
          shall be met if such notice is given at least ten (10) days before the
          time of the sale or disposition. All expenses relating to the
          disposition of the Collateral, including without limitation the
          expenses of retaking, holding, insuring, preparing for sale and
          selling the Collateral, shall become a part of the Indebtedness
          secured by this Agreement and shall be payable on demand, with
          interest at the Note rate from data of expenditure until repaid.

          APPOINT RECEIVER. To the extent permitted by applicable law, Lender
          shall have the following rights and remedies regarding the appointment
          of a receiver (a) Lender may have a receiver appointed as a matter of
          right, (b) the receiver may be an employee of Lender and may serve
          without bond, and (c) all fees of the receiver and his or her attorney
          shall become part of the Indebtedness secured by this Agreement and
          shall be payable on demand, with interest at the Note rate from date
          of expenditure until repaid.

          COLLECT REVENUES, APPLY ACCOUNTS. Lender, either itself or through a
          receiver, may collect the payments, rents, income, and revenues from
          the Collateral. Lender may at any time in its

                                        7

                          COMMERCIAL SECURITY AGREEMENT
                                    CONTINUED

          discretion transfer any Collateral into its own name or that of its
          nominee and receive the payments, rents, income, and revenues
          therefrom and hold the same as security for the Indebtedness or apply
          it to payment of the Indebtedness in such order of preference as
          Lender may determine. Insofar as the Collateral consists of accounts,
          general intangibles, insurance policies, instruments, chattel paper,
          choses in action, or similar property, Lender may demand, collect,
          receipt for, settle, compromise, adjust, sue for, foreclose, or
          realize on the Collateral as Lender may determine, whether or not
          Indebtedness or Collateral is then due. For these purposes, Lender
          may, on behalf of and in the name of Grantor, receive, open and
          dispose of mail addressed to Grantor; change any address to which mail
          and payments are to be sent; and endorse notes, checks, drafts, money
          orders, documents of title, instruments and items pertaining to
          payment, shipment, or storage of any Collateral. To facilitate
          collection, Lender may notify account debtors and obligors on any
          Collateral to make payments directly to Lender.

          OBTAIN DEFICIENCY. If Lender chooses to sell any or all of the
          Collateral, Lender may obtain a judgment against Grantor for any
          deficiency remaining on the Indebtedness due to Lender after
          application of all amounts received from the exercise of the rights
          provided in this Agreement. Grantor shall be liable for a deficiency
          even if the transaction described in this subsection is a sale of
          accounts or chattel paper.

          OTHER RIGHTS AND REMEDIES. Lender shall have all the rights and
          remedies of a secured creditor under the provisions of the Uniform
          Commercial Code, as may be amended from time to time. In addition,
          Lender shall have and may exercise any or all other rights and
          remedies it may have available at law, in equity, or otherwise.

          CUMULATIVE REMEDIES. All of Lender's rights and remedies, whether
          evidenced by this Agreement or the Related Documents or by any other
          writing, shall be cumulative and may be exercised singularly or
          concurrently. Election by Lender to pursue any remedy shall not
          exclude pursuit of any other remedy, and an election to make
          expenditures or to take action to perform an obligation of Grantor
          under this Agreement, after Grantor's failure to perform, shall not
          affect Lender's right to declare a default and to exercise its
          remedies.

          Costs and expenses include Lender's attorneys' fees and legal expenses
          whether or not there is a lawsuit, including attorneys' fees and legal
          expenses for bankruptcy proceedings (and including efforts to modify

          all court costs and such additional fees as may be directed by the
          court.

          CAPTION HEADINGS. Caption headings in this Agreement are for
          convenience purposes only and are not to be used to interpret or
          define the provisions of this Agreement.

          MULTIPLE PARTIES; CORPORATE AUTHORITY. All obligations of Grantor
          under this Agreement shall be joint and several, and all references to
          Grantor shall mean each and every Grantor. This means that each of the
          persons signing below is responsible for all obligations in this
          Agreement.

          NOTICES. All notices required to be given under this Agreement shall
          be given in writing and shall be effective when actually delivered or
          when deposited with a nationally recognized overnight courier or
          deposited in the United States mail, first class, postage prepaid,
          addressed to the party to whom the notice is to be given at the
          address shown above. Any party may change its address for notices
          under this Agreement by giving formal written notice to the other
          parties, specifying that the purpose of the notice is to change the
          party's address. To the extent permitted by applicable law, if there
          is more than one Grantor, notice to any Grantor will constitute notice
          to all Grantors. For notice purposes, Grantor agrees to keep Lender
          informed at all times of Grantor's current address(es).

          POWER OF ATTORNEY. Grantor hereby appoints Lender as its true and
          lawful attorney-in-fact, irrevocably, with full power of substitution
          to do the following, after the occurrence and continuation of an Event
          of Default: (a) to demand, collect, receive, receipt for, sue and
          recover all sums of money or other property which may now or hereafter
          become due, owing or payable from the Collateral; (b) to execute, sign
          and endorse any and all claims, instruments, receipts, checks, drafts
          or warrants issued in payment for the Collateral; (c) to settle or
          compromise any and all claims arising under the Collateral, and, in
          the place and stead of Grantor, to execute and deliver its release and
          settlement for the claim; and (d) to file any claim or claims or to
          take any action or institute or take part in any proceedings, either
          in its own name or in the name of Grantor, or otherwise, which in the
          discretion of Lender may seem to be necessary or advisable. This power
          is given as security for the Indebtedness, and the authority hereby
          conferred is and shall be irrevocable and shall remain in full force
          and effect until renounced by Lender.

          SEVERABILITY. If a court of competent Jurisdiction Ends any provision
          of this Agreement to be invalid or unenforceable as to any person or
          circumstance, such finding shall not render that provision invalid or
          unenforceable as to any other persons or circumstances. If feasible,
          any such offending provision shall be deemed to be modified to be
          within the limes of enforceability or validity; however, if the
          offending provision cannot be so modified, it shall be stricken and
          all other provisions of this Agreement In all other respects shall
          remain valid and enforceable.

          SUCCESSOR INTERESTS. Subject to the limitations set forth above on
          transfer of the Collateral, this

          Agreement shall be binding upon and inure to the benefit of the
          parties, their successors and assigns.

          WAIVER. Lender shall not be deemed to have waived any rights under
          this Agreement unless such waiver is given in writing and signed by
          Lender. No delay or omission on the part of Lender in exercising any
          right shall operate as a waiver of such right or any other right. A
          waiver by Lender of a provision of this Agreement shall not prejudice
          or constitute a waiver of Lender's right otherwise to demand strict
          compliance with that provision or any other provision of this
          Agreement. No prior waiver by Lender, nor any course of dealing
          between Lender and Grantor, shall constitute a waiver of any of
          Lender's rights or of any of Grantors obligations as to any future
          transactions. Whenever the consent of Lender is required under this
          Agreement, the granting of such consent by Lender in any instance
          shall not constitute continuing consent to subsequent instances where
          such consent is required and in all cases such consent may be granted
          or withheld in the sole discretion of Lender.

(b) the grant of options which do not qualify as ISOs ("Non-Qualified Options");
(c) awards of stock in the Company ("Awards"); and (d) opportunities to make
direct purchases of stock in the Company ("Purchases"). Both ISOs and
Non-Qualified Options are referred to hereafter individually as an "Option" and
collectively as "Options." Options, Awards and authorizations to make Purchases
are referred to hereafter collectively as "Stock Rights." As used herein, the
terms "parent" and "subsidiary" mean "parent corporation" and "subsidiary
corporation," respectively, as those terms are defined in Section 424 of the
Code.

         2. ADMINISTRATION OF THE PLAN.

                  A. BOARD OR COMMITTEE ADMINISTRATION. The Plan shall (be
            administered by the Board of Directors of the Company (the "Board")
            or, subject to paragraph 2(D) (relating to compliance with Section
            162(m) of the Code), by a committee appointed by the Board (the
            "Committee"). Hereinafter, all references in this Plan to the
            "Committee" shall mean the Board if no Committee has been appointed.
            Subject to ratification of the grant or authorization of each Stock
            Right by the Board (if so required by applicable state law), and
            subject to the terms of the Plan, the Committee shall have the
            authority to (i) determine to whom (from among the class of
            employees eligible under paragraph 3 to receive ISOs) ISOs shall be
            granted, and to whom (from among the class of individuals and
            entities eligible under paragraph 3 to receive Non-Qualified Options
            and Awards and to make Purchases) Non-Qualified Options, Awards and
            authorizations to make Purchases may be granted; (ii) determine the

            minimum price specified in paragraph 6; (iv) determine whether each
            Option granted shall be an ISO or a Non-Qualified Option; (v)
            determine (subject to paragraph 7) the time or times when each
            Option shall become exercisable and the duration of the exercise
            period; (vi) extend the period during which outstanding Options may
            be exercised; (vii) determine whether restrictions such as
            repurchase options are to be imposed on shares subject to Options,

            and (viii) interpret the Plan and
<PAGE>

                                      -2-

            prescribe and rescind rules and regulations relating to it. If the
            Committee determines to issue a Non-Qualified Option, it shall take
            whatever actions it deems necessary, under Section 422 of the Code
            and the regulations promulgated thereunder, to ensure that such
            Option is not treated as an ISO. The interpretation and construction
            by the Committee of any provisions of the Plan or of any Stock Right
            granted under it shall be final unless otherwise determined by the
            Board. The Committee may from time to time adopt such rules and
            regulations for carrying out the Plan as it may deem advisable. No
            member of the Board or the Committee shall be liable for any action
            or determination made in good faith with respect to the Plan or any
            Stock Right granted under it.

                  B. COMMITTEE ACTIONS. The Committee may select one of its
            members as its chairman, and shall hold meetings at such time and
            places as it may determine. A majority of the Committee shall
            constitute a quorum and acts of a majority of the members of the
            Committee at a meeting at which a quorum is present, or acts reduced
            to or approved in writing by all the members of the Committee (if
            consistent with applicable state law), shall be the valid acts of
            the Committee. From time to time the Board may increase the size of
            the Committee and appoint additional members thereof, remove members
            (with or without cause) and appoint new members in substitution
            therefor, fill vacancies however caused, or remove all members of
            the Committee and thereafter directly administer the Plan.

                  C. GRANT OF STOCK RIGHTS TO BOARD MEMBERS. Stock Rights may be
            granted to members of the Board. All grants of Stock Rights to
            members of the Board shall in all respects be made in accordance
            with the provisions of this Plan applicable to other eligible
            persons. Members of the Board who either (i) are eligible to receive
            grants of Stock Rights pursuant to the Plan or (ii) have been
            granted Stock Rights may vote on any matters affecting the
            administration of the Plan or the grant of any Stock Rights pursuant
            to the Plan, except that no such member shall act upon the granting
            to himself or herself of Stock Rights, but any such member may be
            counted in determining the existence of a quorum at any meeting of
            the Board during which action is taken with respect to the granting
            to such member of Stock Rights.

                  D. PERFORMANCE-BASED COMPENSATION. The Board, in its
            discretion, may take such action as may be necessary to ensure that
            Stock Rights granted under the Plan qualify as "qualified
            performance-based compensation" within the meaning of Section 162(m)
            of the Code and applicable regulations promulgated thereunder
            ("Performance-Based Compensation"). Such action may include, in the
            Board's discretion, some or all of the following (i) if the Board
            determines that Stock Rights granted under the Plan generally shall
            constitute Performance-Based Compensation, the Plan shall be
            administered, to the extent required for such Stock Rights to
            constitute Performance-Based Compensation, by a Committee consisting
            solely of two or more "outside directors" (as defined in
<PAGE>
                                      -3-

            applicable regulations promulgated under Section 162(m) of the
            Code), (ii) if any Non-Qualified Options with an exercise price less
            than the fair market value per share of Common Stock are granted
            under the Plan and the Board determines that such Options should
            constitute Performance-Based Compensation, such options shall be
            made exercisable only upon the attainment of a pre-established,
            objective performance goal established by the Committee, and such
            grant shall be submitted for, and shall be contingent upon
            shareholder approval and (iii) Stock Rights granted under the Plan
            may be subject to such other terms and conditions as are necessary
            for compensation recognized in connection with the exercise or
            disposition of such Stock Right or the disposition of Common Stock
            acquired pursuant to such Stock Right, to constitute
            Performance-Based Compensation.

         3. ELIGIBLE EMPLOYEES AND OTHERS. ISOs may be granted only to employees
of the Company or any Related Corporation. Non-Qualified Options, Awards and
authorizations to make Purchases may be granted to any employee, officer or
director (whether or not also an employee) or consultant of the Company or any
Related Corporation. The Committee may take into consideration a recipient's
individual circumstances in determining whether to grant a Stock Right. The
granting of any Stock Right to any individual or entity shall neither entitle
that individual or entity to, nor disqualify such individual or entity from,
participation in any other grant of Stock Rights.

         4. STOCK. The stock subject to Stock Rights shall be authorized but
unissued shares of Common Stock of the Company, par value $.01 per share (the
"Common Stock"), or shares of Common Stock reacquired by the Company in any
manner. The aggregate number of shares which may be issued pursuant to the Plan
is 1,250,0001, subject to adjustment as provided in paragraph 13. If any Option
granted under the Plan shall expire or terminate for any reason without having
been exercised in full or shall cease for any reason to be exercisable in whole
or in part or shall be repurchased by the Company, the unpurchased shares of
Common Stock subject to such Option shall again be available for grants of Stock
Rights under the Plan.

         No employee of the Company or any Related Corporation may be granted
Options to acquire, in the aggregate, more than 700,000 shares of Common Stock
under the Plan during any fiscal year of the Company. If any Option granted
under the Plan shall expire or terminate for any reason without having been
exercised in full or shall cease for any reason to be exercisable in whole or in
part or shall be repurchased by the Company, the shares subject to such Option
shall be included in the determination of the aggregate number of shares of
Common Stock deemed to have been granted to such employee under the Plan.

         5. GRANTING OF STOCK RIGHTS. Stock Rights may be granted under the Plan
at any time on or after December 10, 1996 and prior to December 10, 2006. The
date of grant of a Stock Right under the Plan will be the date specified by the
Committee at the time it grants the

1 An amendment increasing the number of shares from 1,000,000 to 1,250,000 was
approved by the Board of Directors pursuant to a Unanimous Written Consent of
Directors effective as of February 16, 2000 and was approved by the stockholders
at the Annual Meeting of Stockholders held on March 28, 2000.

Stock Right; provided, however, that such date shall not be prior to the date on
which the Committee acts to approve the grant.

         6. MINIMUM OPTION PRICE; ISO LIMITATIONS.

                  A. PRICE FOR NON-QUALIFIED OPTIONS, AWARDS AND PURCHASES.
            Subject to paragraph 2(D) (relating to compliance with Section
            162(m) of the Code), the exercise price per share specified in the
            agreement relating to each Non-Qualified Option granted, and the
            purchase price per share of stock granted in any Award or authorized
            as a Purchase, under the Plan may be less than the fair market value
            of the Common Stock of the Company on the date of grant; provided
            that, in no event shall such exercise price or such purchase price
            be less than the minimum legal consideration required therefor under
            the laws of any jurisdiction in which the Company or its successors
            in interest may be organized.

                  B. PRICE FOR ISOS. The exercise price per share specified in
            the agreement relating to each ISO granted under the Plan shall not
            be less than the fair market value per share of Common Stock on the
            date of such grant. In the case of an ISO to be granted to an
            employee owning stock possessing more than ten percent (10%) of the
            total combined voting power of all classes of stock of the Company
            or any Related Corporation, the price per share specified in the
            agreement relating to such ISO shall not be less than one hundred
            ten percent (110%) of the fair market value per share of Common
            Stock on the date of grant. For purposes of determining stock
            ownership under this paragraph, the rules of Section 424(d) of the
            Code shall apply.

                  C. $100,000 ANNUAL LIMITATION ON ISO VESTING. Each eligible
            employee may be granted Options treated as ISOs only to the extent
            that, in the aggregate under this Plan and all incentive stock
            option plans of the Company and any Related Corporation, ISOs do not
            become exercisable for the first time by such employee during any
            calendar year with respect to stock having a fair market value
            (determined at the time the ISOs were granted) in excess of
            $100,000. The Company intends to designate any Options granted in
            excess of such limitation as Non-Qualified Options, and the Company
            shall issue separate certificates to the optionee with respect to
            Options that are Non-Qualified Options and Options that are ISOs.

                  D. DETERMINATION OF FAIR MARKET VALUE. If, at the time an
            Option is granted under the Plan, the Company's Common Stock is
            publicly traded, "fair market value" shall be determined as of the
            date of grant or, if the prices or quotes discussed in this sentence
            are unavailable for such date, the last business day for which such
            prices or quotes are available prior to the date of grant and shall
            mean (i) the average (on that date) of the high and low prices of
            the Common Stock on the principal national securities exchange on
            which the Common Stock is traded, if the Common Stock is then traded
            on a national securities exchange; or (ii) the
<PAGE>
                                      -5-

            last reported sale price (on that date) of the Common Stock on the
            Nasdaq National Market, if the Common Stock is not then traded on a
            national securities exchange; or (iii) the closing bid price (or
            average of bid prices) last quoted (on that date) by an established
            quotation service for over-the-counter securities, if the Common
            Stock is not reported on the Nasdaq National Market. If the Common
            Stock is not publicly traded at the time an Option is granted under
            the Plan, "fair market value" shall mean the fair value of the
            Common Stock as determined by the Committee after taking into
            consideration all factors which it deems appropriate, including,
            without limitation, recent sale and offer prices of the Common Stock
            in private transactions negotiated at arm's length.

         7. OPTION DURATION. Subject to earlier termination as provided in
paragraphs 9 and 10 or in the agreement relating to such Option, each Option
shall expire on the date specified by the Committee, but not more than (i) ten
years from the date of grant in the case of Options generally and (ii) five
years from the date of grant in the case of ISOs granted to an employee owning
stock possessing more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or any Related Corporation, as determined
under paragraph 6(B). Subject to earlier termination as provided in paragraphs 9
and 10, the term of each ISO shall be the term set forth in the original
instrument granting such ISO, except with respect to any part of such ISO that
is converted into a Non-Qualified Option pursuant to paragraph 16.

         8. EXERCISE OF OPTION.  Subject to the provisions of paragraphs 9
through 12, each Option granted under the Plan shall be exercisable as follows:

                  A. VESTING. The Option shall either be fully exercisable on
            the date of grant or shall become exercisable thereafter in such
            installments as the Committee may specify.

                  B. FULL VESTING OF INSTALLMENTS. Once an installment becomes
            exercisable, it shall remain exercisable until expiration or
            termination of the Option, unless otherwise specified by the
            Committee.

                  C. PARTIAL EXERCISE. Each Option or installment may be
            exercised at any time or from time to time, in whole or in part, for
            up to the total number of shares with respect to which it is then
            exercisable.

                  D. ACCELERATION OF VESTING. The Committee shall have the right
            to accelerate the date that any installment of any Option becomes
            exercisable; provided that the Committee shall not, without the
            consent of an optionee, accelerate the permitted exercise date of
            any installment of any Option granted to any employee as an ISO (and
            not previously converted into a Non-Qualified Option pursuant to
            paragraph 16) if such acceleration would violate the annual vesting
            limitation contained in Section 422(d) of the Code, as described in
            paragraph 6(C).
<PAGE>
                                      -6-

         9. TERMINATION OF EMPLOYMENT. Unless otherwise specified in the
agreement relating to such ISO, if an ISO optionee ceases to be employed by the
Company and all Related Corporations other than by reason of death or disability
as defined in paragraph 10, no further installments of his or her ISOs shall
become exercisable, and his or her ISOs shall terminate on the earlier of (a)
three months after the date of termination of his or her employment, or (b)
their specified expiration dates, except to the extent that such ISOs (or
unexercised installments thereof) have been converted into Non-Qualified Options
pursuant to paragraph 16. For purposes of this paragraph 9, employment shall be
considered as continuing uninterrupted during any bona fide leave of absence
(such as those attributable to illness, military obligations or governmental
service) provided that the period of such leave does not exceed 90 days or, if
longer, any period during which such optionee's right to reemployment is
guaranteed by statute or by contract. A bona fide leave of absence with the
written approval of the Committee shall not be considered an interruption of
employment under this paragraph 9, provided that such written approval
contractually obligates the Company or any Related Corporation to continue the
employment of the optionee after the approved period of absence. ISOs granted
under the Plan shall not be affected by any change of employment within or among
the Company and Related Corporations, so long as the optionee continues to be an
employee of the Company or any Related Corporation. Nothing in the Plan shall be
deemed to give any grantee of any Stock Right the right to be retained in
employment or other service by the Company or any Related Corporation for any
period of time.

         10. DEATH; DISABILITY.

                  A. DEATH. If an ISO optionee ceases to be employed by the
            Company and all Related Corporations by reason of his or her death,
            any ISO owned by such optionee may be exercised, to the extent
            otherwise exercisable on the date of death, by the estate, personal
            representative or beneficiary who has acquired the ISO by will or by
            the laws of descent and distribution, until the earlier of (i) the
            specified expiration date of the ISO or (ii) 180 days from the date
            of the optionee's death.

                  B. DISABILITY. If an ISO optionee ceases to be employed by the
            Company and all Related Corporations by reason of his or her
            disability, such optionee shall have the right to exercise any ISO
            held by him or her on the date of termination of employment, for the
            number of shares for which he or she could have exercised it on that
            date, until the earlier of (i) the specified expiration date of the
            ISO or (ii) 180 days from the date of the termination of the
            optionee's employment. For the purposes of the Plan, the term
            "disability" shall mean "permanent and total disability" as defined
            in Section 22(e)(3) of the Code or any successor statute.

         11. ASSIGNABILITY. No ISO shall be assignable or transferable by the
optionee except by will or by the laws of descent and distribution, and during
the lifetime of the optionee shall be
<PAGE>
                                      -7-

exercisable only by such optionee. Stock Rights other than ISOs shall be
transferable to the extent set forth in the agreement relating to such Stock
Right.

         12. TERMS AND CONDITIONS OF OPTIONS. Options shall be evidenced by
instruments (which need not be identical) in such forms as the Committee may
from time to time approve. Such instruments shall conform to the terms and
conditions set forth in paragraphs 6 through 11 hereof and may contain such
other provisions as the Committee deems advisable which are not inconsistent
with the Plan, including restrictions applicable to shares of Common Stock
issuable upon exercise of Options. The Committee may specify that any
Non-Qualified Option shall be subject to the restrictions set forth herein with
respect to ISOs, or to such other termination and cancellation provisions as the
Committee may determine. The Committee may from time to time confer authority
and responsibility on one or more of its own members and/or one or more officers
of the Company to execute and deliver such instruments. The proper officers of
the Company are authorized and directed to take any and all action necessary or
advisable from time to time to carry out the terms of such instruments.

         13. ADJUSTMENTS. Upon the occurrence of any of the following events, an
optionee's rights with respect to Options granted to such optionee hereunder
shall be adjusted as hereinafter provided, unless otherwise specifically
provided in the written agreement between the optionee and the Company relating
to such Option:

                  A. STOCK DIVIDENDS AND STOCK SPLITS. If the shares of Common
            Stock shall be subdivided or combined into a greater or smaller
            number of shares or if the Company shall issue any shares of Common
            Stock as a stock dividend on its outstanding Common Stock, the
            number of shares of Common Stock deliverable upon the exercise of
            Options shall be appropriately increased or decreased
            proportionately, and appropriate adjustments shall be made in the
            purchase price per share to reflect such subdivision, combination or
            stock dividend.

                  B. CONSOLIDATIONS OR MERGERS. If the Company is to be
            consolidated with or acquired by another entity in a merger or other
            reorganization in which the holders of the outstanding voting stock
            of the Company immediately preceding the consummation of such event,
            shall, immediately following such event, hold, as a group, less than
            a majority of the voting securities of the surviving or successor
            entity, or in the event of a sale of all or substantially all of the
            Company's assets or otherwise (each, an "Acquisition"), the
            Committee or the board of directors of any entity assuming the
            obligations of the Company hereunder (the "Successor Board"), shall,
            as to outstanding Options, either (i) make appropriate provision for
            the continuation of such Options by substituting on an equitable
            basis for the shares then subject to such Options either (a) the
            consideration payable with respect to the outstanding shares of
            Common Stock in connection with the Acquisition, (b) shares of stock
            of the surviving or successor corporation or (c) such other
            securities as the Successor Board deems appropriate, the fair market
            value of which shall not materially exceed the fair
<PAGE>
                                      -8-

            market value of the shares of Common Stock subject to such Options
            immediately preceding the Acquisition; or (ii) upon written notice
            to the optionees, provide that all Options must be exercised, to the
            extent then exercisable or to be exercisable as a result of the
            Acquisition, within a specified number of days of the date of such
            notice, at the end of which period the Options shall terminate; or
            (iii) terminate all Options in exchange for a cash payment equal to
            the excess of the fair market value of the shares subject to such
            Options (to the extent then exercisable or to be exercisable as a
            result of the Acquisition) over the exercise price thereof.

                  C. RECAPITALIZATION OR REORGANIZATION. In the event of a
            recapitalization or reorganization of the Company (other than a
            transaction described in subparagraph B above) pursuant to which
            securities of the Company or of another corporation are issued with
            respect to the outstanding shares of Common Stock, an optionee upon
            exercising an Option shall be entitled to receive for the purchase
            price paid upon such exercise the securities he or she would have
            received if he or she had exercised such Option prior to such
            recapitalization or reorganization.

                  D. MODIFICATION OF ISOS. Notwithstanding the foregoing, any
            adjustments made pursuant to subparagraphs A, B or C with respect to
            ISOs shall be made only after the Committee, after consulting with
            counsel for the Company, determines whether such adjustments would
            constitute a "modification" of such ISOs (as that term is defined in
            Section 424 of the Code) or would cause any adverse tax consequences
            for the holders of such ISOs. If the Committee determines that such
            adjustments made with respect to ISOs would constitute a
            modification of such ISOs or would cause adverse tax consequences to
            the holders, it may refrain from making such adjustments.

                  E. DISSOLUTION OR LIQUIDATION. In the event of the proposed
            dissolution or liquidation of the Company, each Option will
            terminate immediately prior to the consummation of such proposed
            action or at such other time and subject to such other conditions as
            shall be determined by the Committee.

                  F. ISSUANCES OF SECURITIES. Except as expressly provided
            herein, no issuance by the Company of shares of stock of any class,
            or securities convertible into shares of stock of any class, shall
            affect, and no adjustment by reason thereof shall be made with
            respect to, the number or price of shares subject to Options. No
            adjustments shall be made for dividends paid in cash or in property
            other than securities of the Company.

                  G. FRACTIONAL SHARES. No fractional shares shall be issued
            under the Plan and the optionee shall receive from the Company cash
            in lieu of such fractional shares.
<PAGE>
                                      -9-

                  H. ADJUSTMENTS. Upon the happening of any of the events
            described in subparagraphs A, B or C above, the class and aggregate
            number of shares set forth in paragraph 4 hereof that are subject to
            Stock Rights which previously have been or subsequently may be
            granted under the Plan shall also be appropriately adjusted to
            reflect the events described in such subparagraphs. The Committee or
            the Successor Board shall determine the specific adjustments to be
            made under this paragraph 13 and, subject to paragraph 2, its
            determination shall be conclusive.

         14. MEANS OF EXERCISING OPTIONS. An Option (or any part or installment
thereof) shall be exercised by giving written notice to the Company at its
principal office address, or to such transfer agent as the Company shall
designate. Such notice shall identify the Option being exercised and specify the
number of shares as to which such Option is being exercised, accompanied by full
payment of the purchase price therefor either (a) in United States dollars in
cash or by check, (b) at the discretion of the Committee, through delivery of
shares of Common Stock having a fair market value equal as of the date of the
exercise to the cash exercise price of the Option, (c) at the discretion of the
Committee, by delivery of the grantee's personal recourse note bearing interest
payable not less than annually at no less than 100% of the lowest applicable
Federal rate, as defined in Section 1274(d) of the Code, (d) at the discretion
of the Committee and consistent with applicable law, through the delivery of an
assignment to the Company of a sufficient amount of the proceeds from the sale
of the Common Stock acquired upon exercise of the Option and an authorization to
the broker or selling agent to pay that amount to the Company, which sale shall
be at the participant's direction at the time of exercise, or (e) at the
discretion of the Committee, by any combination of (a), (b), (c) and (d) above.
If the Committee exercises its discretion to permit payment of the exercise
price of an ISO by means of the methods set forth in clauses (b), (c), (d) or
(e) of the preceding sentence, such discretion shall be exercised in writing at
the time of the grant of the ISO in question. The holder of an Option shall not
have the rights of a shareholder with respect to the shares covered by such
Option until the date of issuance of a stock certificate to such holder for such
shares. Except as expressly provided above in paragraph 13 with respect to
changes in capitalization and stock dividends, no adjustment shall be made for
dividends or similar rights for which the record date is before the date such
stock certificate is issued.

         15. TERM AND AMENDMENT OF PLAN. This Plan was adopted by the Board on
December 10, 1996, subject, with respect to the validation of ISOs granted under
the Plan, to approval of the Plan by the stockholders of the Company at the next
Meeting of Stockholders or, in lieu thereof, by written consent. If the approval
of stockholders is not obtained prior to December 10, 1997, any grants of ISOs
under the Plan made prior to that date will be rescinded. The Plan shall expire
at the end of the day on December 9, 2006 (except as to Options outstanding on
that date). Subject to the provisions of paragraph 5 above, Options may be
granted under the Plan prior to the date of stockholder approval of the Plan.
The Board may terminate or amend the Plan in any respect at any time, except
that, without the approval of the stockholders obtained within 12 months before
or after the Board adopts a resolution authorizing any of the following actions:
(a) the total number of shares that may be issued under the Plan
<PAGE>
                                      -10-

may not be increased (except by adjustment pursuant to paragraph 13); (b) the
provisions of paragraph 3 regarding eligibility for grants of ISOs may not be
modified; (c) the provisions of paragraph 6(B) regarding the exercise price at
which shares may be offered pursuant to ISOs may not be modified (except by
adjustment pursuant to paragraph 13); and (d) the expiration date of the Plan
may not be extended. Except as otherwise provided in this paragraph 15, in no
event may action of the Board or stockholders alter or impair the rights of a
grantee, without such grantee's consent, under any Stock Right previously
granted to such grantee.

         16. MODIFICATIONS OF ISOS; CONVERSION OF ISOS INTO NON-QUALIFIED
OPTIONS. Subject to paragraph 13(D), without the prior written consent of the
holder of an ISO, the Committee shall not alter the terms of such ISO (including
the means of exercising such ISO) if such alteration would constitute a
modification (within the meaning of Section 424(h)(3) of the Code). The
Committee, at the written request or with the written consent of any optionee,
may in its discretion take such actions as may be necessary to convert such
optionee's ISOs (or any installments or portions of installments thereof) that
have not been exercised on the date of conversion into Non-Qualified Options at
any time prior to the expiration of such ISOs, regardless of whether the
optionee is an employee of the Company or a Related Corporation at the time of
such conversion. Such actions may include, but shall not be limited to,
extending the exercise period or reducing the exercise price of the appropriate
installments of such ISOs. At the time of such conversion, the Committee (with
the consent of the optionee) may impose such conditions on the exercise of the
resulting Non-Qualified Options as the Committee in its discretion may
determine, provided that such conditions shall not be inconsistent with this
Plan. Nothing in the Plan shall be deemed to give any optionee the right to have
such optionee's ISOs converted into Non-Qualified Options, and no such
conversion shall occur until and unless the Committee takes appropriate action.
Upon the taking of such action, the Company shall issue separate certificates to
the optionee with respect to Options that are Non-Qualified Options and Options
that are ISOs.

         17. APPLICATION OF FUNDS. The proceeds received by the Company from the
sale of shares pursuant to Options granted and Purchases authorized under the
Plan shall be used for general corporate purposes.

         18. NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION. By accepting an ISO
granted under the Plan, each optionee agrees to notify the Company in writing
immediately after such optionee makes a Disqualifying Disposition (as described
in Sections 421, 422 and 424 of the Code and regulations thereunder) of any
stock acquired pursuant to the exercise of ISOs granted under the Plan. A
Disqualifying Disposition is generally any disposition occurring on or before
the later of (a) the date two years following the date the ISO was granted or
(b) the date one year following the date the ISO was exercised.

         19. WITHHOLDING OF ADDITIONAL INCOME TAXES. Upon the exercise of a
Non-Qualified Option, the transfer of a Non-Qualified Stock Option pursuant to
an arm's-length transaction, the grant of an Award, the making of a Purchase of
Common Stock for less than its fair market value, the making of a Disqualifying
Disposition (as defined in paragraph 18), the vesting or transfer of restricted
stock or securities acquired on the exercise of an Option
<PAGE>
                                      -11-

hereunder, or the making of a distribution or other payment with respect to such
stock or securities, the Company may withhold taxes in respect of amounts that
constitute compensation includible in gross income. The Committee in its
discretion may condition (i) the exercise of an Option, (ii) the transfer of a
Non-Qualified Stock Option, (iii) the grant of an Award, (iv) the making of a
Purchase of Common Stock for less than its fair market value, or (v) the vesting
or transferability of restricted stock or securities acquired by exercising an
Option, on the grantee's making satisfactory arrangement for such withholding.
Such arrangement may include payment by the grantee in cash or by check of the
amount of the withholding taxes or, at the discretion of the Committee, by the
grantee's delivery of previously held shares of Common Stock or the withholding
from the shares of Common Stock otherwise deliverable upon exercise of a Option
shares having an aggregate fair market value equal to the amount of such
withholding taxes.

         20. GOVERNMENTAL REGULATION. The Company's obligation to sell and
deliver shares of the Common Stock under this Plan is subject to the approval of
any governmental authority required in connection with the authorization,
issuance or sale of such shares.

         Government regulations may impose reporting or other obligations on the
Company with respect to the Plan. For example, the Company may be required to
send tax information statements to employees and former employees that exercise
ISOs under the Plan, and the Company may be required to file tax information
returns reporting the income received by grantees of Options in connection with
the Plan.

         21. GOVERNING LAW. The validity and construction of the Plan and the
instruments evidencing Stock Rights shall be governed by the laws of the State
of Delaware, or the laws of any jurisdiction in which the Company or its
successors in interest may be organized.
