6.  STOCK OPTIONS -- TERMS AND CONDITIONS

     All Stock Options granted under the Plan shall be evidenced by Agreements
which shall be subject to applicable provisions of the Plan, and such other
provisions as the Committee may adopt, including the following provisions:

          (a) Price:  The Exercise Price per share shall not be less than 100%
     of the Fair Market Value of a share of Common Stock on the date of Award
     provided that without shareholder approval no option shall be repriced or
     rescinded.

          (b) Period:  Except as provided in Paragraph 6(f) below, the Committee
     may establish the term of any Option awarded under the Plan, provided,
     however, that an Option shall expire no later than ten (10) years from the
     date of Award.

          (c) Time of Exercise:  Subject to the provisions of Paragraph 10
     below, the Committee shall establish installment exercise terms in Awards
     to Employees based on the Company's publicly traded share price, and may
     establish installment exercise terms based on the passage of time or
     otherwise, such that the Option becomes fully exercisable in a series of
     cumulating portions. The Committee may also establish other conditions of
     exercise as it shall determine and may accelerate the exercisability of any
     Option granted to an Employee under the Plan.

          (d) Exercise:  An Option, or portion thereof, shall be exercised by
     delivery of a written notice of exercise to the Corporation and payment of
     the full price of the shares being exercised. Payment may be made: (i) in
     United States dollars in cash or by check, bank draft or money order
     payable to the order of the Corporation, or (ii) through the delivery of
     shares of Common Stock which have been held by a
<PAGE>

     Participant for at least six months with a value equal to the Option Price,
     provided that the use by an Employee (but not a Non-Employee Director) of
     previously acquired shares shall be subject to the approval of the
     Committee, or (iii) by a combination of both (i) and (ii) above. The
     Committee shall determine acceptable methods for tendering Common Stock as
     payment upon exercise of an Option and may impose such limitations and
     prohibitions on the use of Common Stock to exercise an Option as it deems
     appropriate. A Participant shall not have any of the rights or privileges
     of a holder of Common Stock until such time as shares of Common Stock are
     issued or transferred to the Participant.

          (e) Special Rules for Incentive Stock Options:  Notwithstanding any
     other provision of the Plan, in the case of any Incentive Stock Option
     granted under the Plan, the following provisions will apply:

             (i) The aggregate Fair Market Value (determined at the time the
        Option is granted) of the shares of stock with respect to which
        Incentive Stock Options are exercisable for the first time by a
        Participant under the Plan or any other plan of the Corporation or any
        Subsidiary or any corporation which is a parent corporation (as defined
        in Section 424(e) of the Code) of the Corporation, in any calendar year,
        shall not exceed $100,000 (or such other individual employee maximum as
        may be in effect from time to time under the Code at the time the
        Incentive Stock Option is awarded).

             (ii) Any Participant who disposes of shares of Common Stock
        acquired on the exercise of an Incentive Stock Option by sale or
        exchange either (A) within two years after the date of the grant of the
        Option under which the stock was acquired or (B) within one year after
        the acquisition of such shares shall notify the Corporation of such
        disposition and of the amount realized upon such disposition.

     (f) Special Rules for Grants to Non-Employee Directors:  Notwithstanding
any other provision of the Plan, grants to Non-Employee Directors shall be made
pursuant to the following provisions:

             (i) On the date of the first meeting of the Board after each Annual
        Meeting of Stockholders of the Company occurring during the term of this
        Plan, each Non-Employee Director shall receive an award of Non-qualified
        Options to purchase 2,000 shares of Common Stock;

             (ii) All options granted to Non-Employee Directors pursuant to
        paragraph (i) shall have an exercise price equal to the fair market
        value of the Common Stock on the date of grant, a term of ten years, and
        shall become exercisable, subject to the provisions of the Plan, six
        months after the grant date provided that without shareholder approval
        no option shall be repriced or rescinded; and

             (iii) Non-Employee Directors shall not be eligible for any grants
        under the Plan other than those provided for in paragraph (i) above.

          (g) Proceeds on Exercise:  The proceeds of the sale of the Common
     Stock subject to Option are to be added to the general funds of the
     Corporation and used for its corporate purposes.

          (h) Deferral on Exercise:  If the Corporation maintains an appropriate
     deferred compensation plan available for such purpose, the Committee, in
     its discretion, may permit a Participant to elect to defer the receipt of
     Common Stock which would otherwise be issued upon the exercise of Options
     as provided in such deferred plan.

7.  TERMINATION OF EMPLOYMENT

     (a) In the event a Participant (other than a Non-Employee Director) shall
cease to be employed by the Corporation or any Subsidiary while he is holding
one or more Options, each outstanding Option, or any portion thereof, which is
exercisable on the date of such termination shall expire at the earlier of the
expiration of its term or the following:

          (i) one year, in the case of a "non-qualified" Stock Option, and three
     months, in the case of an Incentive Stock Option, after termination due to
     normal retirement, late retirement or earlier retirement with Committee
     consent, under a formal plan or policy of the Corporation;

          (ii) one year after termination due to disability within the meaning
     of Section 22(e)(3) of the Code as determined by the Committee;
<PAGE>

          (iii) one year after the Participant's death; or

          (iv) coincident with the date of termination if due to any other
     reason, except as and to the extent that the Committee may determine
     otherwise. In the event of death within the up to three month or one year
     period set forth in clause (i) above, as appropriate, after normal or early
     retirement while any portion of the Option remains exercisable, the
     Committee in its discretion may provide for an extension of the exercise
     period of up to one year after the Participant's death but not beyond the
     expiration of the term of the Option.

     (b) For the purposes of this paragraph 7, it shall not be considered a
termination of employment when a Participant is placed by the Corporation or any
Subsidiary on a military or sick leave or such other type of leave of absence
which is considered as continuing intact the employment relationship of the
Participant. In the case of such leave of absence the employment relationship
shall be continued until the later of the date when such leave equals ninety
(90) days or the date when the Participant's right to reemployment with the
Corporation or such Subsidiary shall no longer be guaranteed either by statute
or contract.

     Unless otherwise determined by the Committee, any portion of an Option held
by a Participant (other than a Non-Employee Director) that is not exercisable on
the date such Participant's employment terminates shall expire as of such
termination date.

8.  TERMINATION OF SERVICE AS DIRECTOR

     (a) In the event a Director shall cease to serve as a Director of the
Corporation while he or she is holding one or more Options, each outstanding
Option which is exercisable as of the date of such termination shall expire at
the earlier of the expiration of its term or the following:

          (i) one year after termination of service due to retirement under a
     mandatory retirement policy of the Board as may be in effect on the date of
     such termination of service;

          (ii) one year after termination of service due to disability within
     the meaning of Section 22(e)(3) of the Code;

          (iii) one year after termination of service due to the Director's
     death; or

          (iv) coincident with the date service terminates for any other reason.

     (b) Any Options which have not become exercisable as of the date a Director
ceases to serve as a Director of the Corporation shall terminate as of such
date.

9.  ADJUSTMENTS

     In the event that a stock dividend, stock split or other subdivision,
recapitalization, reorganization, merger, consolidation or change in the shares
of Common Stock, extraordinary cash dividend, spin-off or other similar event
affects the Common Stock, then if the Committee shall determine in its sole
discretion that such change equitably requires an adjustment in the number or
kind of shares which may be awarded under the Plan or in the number or kind of
shares covered by any outstanding Options, and/or in such Option's Exercise
Price, such adjustments shall be made by the Committee and shall be conclusive
and binding upon eligible Participants and for all purposes of the Plan.

10.  CHANGE IN CONTROL

     (a) Accelerated Vesting and Payment.  Subject to the provisions of
Paragraph 10(b) below, in the event of a Change in Control, each Option
(including an Option held by a Non-Employee Director) whether or not currently
exercisable shall promptly be canceled in exchange for a payment in cash of an
amount equal to the excess of the Change of Control Price over the Exercise
Price for such Option.

     (b) Alternative Awards.  Notwithstanding Paragraph 10(a), no cancellation
and cash settlement shall occur with respect to any Award or class of Awards if
the Committee reasonably determines in good faith prior to the occurrence of a
Change of Control that such Award or class of Awards shall be honored or
assumed, or new rights substituted therefor (such honored, assumed or
substituted award hereinafter called an
<PAGE>

"Alternative Award") by a Participant's employer (or the parent or a subsidiary
of such employer) immediately following the Change of Control, provided that any
such Alternative Award must:

          (i) be based on stock which is traded on an established securities
     market, or which will be so traded within 60 days following the Change of
     Control;

          (ii) provide such Participant (or each Participant in a class of
     Participants) with rights and entitlements substantially equivalent to or
     better than the rights and entitlements applicable under such Award;

          (iii) have substantially equivalent economic value to such Award
     (determined by the Committee as constituted immediately prior to the Change
     in Control, in its sole discretion, promptly after a Change in Control);
     and

          (iv) have terms and conditions which provide that following a Change
     of Control, any conditions on a Participant's rights under, or any
     restrictions or conditions on transfer or exercisability applicable to each
     such Award, shall be waived or lapse as the case may be.

11.  AMENDMENT AND TERMINATION OF PLAN

     (a) The Board, without further approval of the Stockholders, may at any
time, and from time to time, suspend or terminate the Plan in whole or in part
or amend it from time to time in such respects as the Board may deem appropriate
and in the best interests of the Corporation; provided, however, that no such
amendment shall be made, without approval of the Stockholders, which would:

          (i) materially modify the eligibility requirements for Participants;

          (ii) increase the total number of shares of Common Stock which may be
     issued pursuant to Stock Options, except as is provided for in accordance
     with Paragraph 9 under the Plan;

          (iii) decrease the minimum Exercise Price per share;

          (iv) extend the period for granting Stock Options;

the Plan relating to Options granted to or held by Non-Employee Directors within
six months of the last date on which any such provision was amended.

     (c) No amendment, suspension or termination of this Plan shall, without the
Participant's consent, alter or impair any of the rights or obligations under
any Award theretofore granted to her or him under the Plan.

     (d) The Board may amend the Plan, subject to the limitations cited above,
in such manner as it deems necessary to permit the granting of Stock Options
meeting the requirements of future amendments or issued regulations, if any, to
the Code.

12.  GOVERNMENT AND OTHER REGULATIONS

     The granting of Stock Options under the Plan and the obligation of the
Corporation to issue, or transfer and deliver shares for Stock Options exercised
under the Plan shall be subject to all applicable laws, regulations, rules and
orders which shall then be in effect.

13.  UNFUNDED PLAN

     The Plan, insofar as it provides for payments, shall be unfunded and the
Corporation shall not be required to segregate any assets which may at any time
be subject to Awards under the Plan. Any liability of the Corporation to any
person with respect to any Award under this Plan shall be based solely upon any
contractual obligations which may be created by Agreements reflecting grants or
Awards under this Plan.
<PAGE>

14.  MISCELLANEOUS PROVISIONS

     (a) Rights to Continued Employment:  No person shall have any claim or
right to be granted an Award under the Plan, and the grant of an Award under the
Plan shall not be construed as giving any Participant the right to be retained
in the employ of the Corporation or any Subsidiary corporation of the
Corporation and the Corporation expressly reserves the right at any time to
dismiss a Participant with or without cause, free from any liability, or any
claim under the Plan, except as provided herein or in an Agreement.

     (b) Rights to Serve as a Director:  This Plan shall not impose any
obligation on the Company to retain any individual as a Non-Employee Director
nor shall it impose any obligation on the part of any Non-Employee Director to
remain as a director of the Company, provided that each Non-Employee Director by
accepting each award under the Plan shall represent to the Company that it is
his good faith intention to continue to serve as a director of the Company until
its next annual meeting of stockholders and that he agrees to do so unless a
change in circumstances arises.

     (c) No Obligation to Exercise Option:  The granting of an Option shall
impose no obligation upon the Participant to exercise such Option.

     (d) Who Shall Exercise:  During a Participant's lifetime, Options may be
exercised only by the Participant except as provided by the Plan or as otherwise
specified by the Committee in the case of Options which are not Incentive Stock
Options.

     (e) Non-Transferability:  An award may be transferred to a member of the
Participant's immediate family or to a trust or similar vehicle for the benefit
of such immediate family members or to a charitable trust (collectively, the
"Permitted Transferees"), provided that except as permitted by this section no
award shall be assignable or transferable except by will or the laws of descent
and distribution, and except to the extent required by law, no right or interest
of any Participant shall be subject to any lien, obligation or liability of the
Participant. All rights with respect to awards granted to a Participant under
the Plan shall be exercisable during his lifetime only by such Participant or,
if applicable, the Permitted Transferees. The rights of a Permitted Transferee
shall be limited to the rights conveyed to such Transferee, who shall be subject
to and bound by the terms of the agreement or agreements between the Participant
and the Corporation."

     (f) Withholding Taxes:  The Corporation may require a payment to cover
applicable withholding for income and employment taxes in the event of the
exercise of a Stock Option. At any time when a Participant is required to pay to
the Corporation an amount required to be withheld under applicable income tax
laws in connection with the exercise of a Stock Option, the Participant may
satisfy this obligation in whole or in part by electing (the "Election") to have
the Corporation withhold shares of Common Stock having a value equal to the
amount required to be withheld. The value of the shares to be withheld shall be
equal to the Fair Market Value of the Common Stock, as determined on the date
that the amount of tax to be withheld shall be determined (the "Tax Date"). Each
Election must be made prior to the Tax Date pursuant to such rules as the
Committee shall establish. The Committee may disapprove of any Election or may
suspend or terminate the right to make Elections. An Election is irrevocable.

     (g) Plan Expenses:  Any expenses of administering this Plan shall be borne
by the Corporation.

     (h) Legal Considerations:  The Corporation shall not be required to issue
shares of Common Stock under the Plan until all applicable legal, listing or
registration requirements, as determined by legal counsel, have been satisfied,
including, if necessary, appropriate written representations from Participants.

     (i) Other Plans:  Nothing contained herein shall prevent the Corporation
from establishing other incentive and benefit plans in which Participants in the
Plan may also participate.

     (j) No Warranty of Tax Effect:  Except as may be contained in any
Agreement, no opinion shall be deemed to be expressed or warranties made as to
the effect for foreign, federal, state or local tax purposes of any Awards.

     (k) Construction of Plan:  The validity, construction, interpretation,
administration and effect of the Plan and of its rules and regulations, and
rights relating to the Plan, shall be determined in accordance with the laws of
the State of Delaware.
