          (a)  This Plan shall be administered by the Board or by a committee

     administer this Plan. To the extent possible and advisable, the Committee

     rules and procedures relating to the administration of this Plan. All
     actions of the Committee in connection with the interpretation and
     administration of this Plan shall be binding upon all parties. Subject to
     the limitations set forth below, the Committee is expressly authorized to
     make such modifications to this Plan and the Options granted hereunder as
     are necessary to effectuate the intent of this Plan as a result of any
     changes in the tax,

                                      -2-


     accounting, or securities laws treatment of Participants and the Plan. The
     Committee may delegate its responsibilities to others under such conditions
     and limitations as it may prescribe.

          (c)  If the Company enters into a transaction that is intended to
     qualify for the pooling of interests method of accounting, but it is
     determined that one or more Options (or an aspect of an Option) could
     preclude such treatment, then the Committee may modify (to the minimum
     extent required) or revoke (if necessary) the Option or Options (or any
     provision or provisions thereof) to the extent necessary for the
     transaction to be subject to pooling of interests method of accounting.

     6.   Effective Date of this Plan.  This Plan shall be effective on
          ---------------------------
December 17, 1999, provided it is approved by the holders of a majority of the
Company's common stock, at the Company's 1999 Annual Meeting.  If the Plan is
not approved by the stockholders at that meeting, the Plan and all Options
issued under the Plan will terminate.  The approval by the stockholders must
relate to:

          (a)  The class of individuals who are entitled to receive Incentive
     Stock Options; and

          (b)  The maximum number of shares of Common Stock that may be issued
     under the Plan, except as adjusted pursuant to Section 12 of this Plan.

If either of those items is changed, the approval of the stockholders must again
be obtained.

      7.  Termination of Plan.  This Plan shall terminate on December 16, 2009,
          -------------------
except with respect to Options then outstanding. However, the Board may elect to
terminate the Plan on a prior date. The termination of this Plan shall not
adversely affect the rights of any Participant with respect to any Option
outstanding as of the time of such termination.

     8.   Shares Subject to this Plan.
          ---------------------------

          (a)  The maximum number of shares of Common Stock which may be issued
     pursuant to this Plan shall be three million (3,000,000).  Upon the
     expiration or termination of any Option granted under this Plan which shall
     not have been exercised in full, the shares of Common Stock remaining
     unissued under such Option shall again become available for granting under
     the Plan.

          (b)  The maximum number of shares of Common Stock which may be
     issuable pursuant to Options granted during any calendar year to any
     Participant is five hundred thousand (500,000) shares.  For purposes of
     determining the maximum number of shares that may be issued to a single
     Participant, shares subject to a terminated Option shall be considered
     outstanding.

                                      -3-


          (c)  In the event a Participant pays part or all of the exercise price
     of an Option by surrendering shares of Common Stock that the Participant
     previously acquired, only the number of shares issuable to the Participant
     in excess of those surrendered shall be taken into account for purposes of
     determining the maximum number of shares that may be issued under the Plan,
     both as to that Participant and in the aggregate (to all Participants).

     9.   Form of Options.
          ---------------

          (a)  Options shall be granted under this Plan on such terms and in
     such form as the Committee may approve, which shall not be inconsistent
     with the provisions of this Plan, but which need not be the same for each
     such grant. Options may be either Nonqualified Stock Options or Incentive
     Stock Options.

          (b)  The terms and conditions of each Option shall include, in
     addition to such other terms and conditions as may be established by the
     Committee, (i) the per share exercise price of such Option (ii) the
     termination date of such Option, which shall not be later than seven (7)
     years after the date of grant, and (iii) the effect on such Option of the
     termination of the Participant's employment.

          (c)  Any Option which is intended, as evidenced by its designation, as
     an Incentive Stock Option shall be made subject to such terms and
     conditions as may be required for such Option to qualify as an Incentive
     Stock Option.  Incentive Stock Options granted under this Plan shall also
     include a requirement that the Participant receiving such Incentive Stock
     Option must notify the Company if he or she disposes of Common Stock
     acquired pursuant to the exercise thereof prior to the expiration of the
     holding periods prescribed in Section 422(a)(1) of the Code.

          (d)  Any Option which is intended, as evidenced by its designation, as
     a Non-Qualified Stock Option shall have an exercise price that is not less
     than the fair market value of the Common Stock on the date of grant of such
     Option.

          (e)  If an Option is intended to be exempt from the million dollar
     compensation deduction limitation of Code Section 162(m), the option price
     must be at least equal to the Fair Market Value of the Common Stock on the
     date of the grant and the grant must be made by a committee composed
     exclusively of two (2) or more "outside directors" as that term is defined
     under Code Section 162(m).

     10.  Modification of Options.
          -----------------------

          (a)  The Committee may modify any outstanding Option as it deems
     appropriate.  Such authority shall include, without limitation, the right
     to accelerate the right to exercise any Option, extend or renew any Option,
     as well as to modify any

                                      -4-


     restrictions with respect to any Option.  However, in no event will the
     exercise price of any outstanding Option be reduced or repriced (as
     determined under applicable accounting standards), including any repricing
     effected by issuing replacement stock options for outstanding stock options
     that have an exercise price greater than the fair market value of the
     Common Stock, without first obtaining stockholder approval.

          (b)  No modification may be made to any Option that would adversely
     affect the rights of the Participant with respect to any outstanding Option
     without such Participant's consent.

          (c)  In the event that the Board amends the terms of an Option so that
     it no longer qualifies as an Incentive Stock Option, the limitations
     imposed upon the Option under the Code and the Plan by virtue of it
     (formerly) qualifying as an Incentive Stock Option shall no longer apply,
     to the extent specified in the amendment.

          (d)  Whether a modification of an existing Incentive Stock Option will
     be treated as the issuance of a new Incentive Stock Option will be
     determined in accordance with the rules of Code Section 424(h).  Whether a
     modification of an existing Option previously granted will be treated as a
     new grant for purposes of Section 16 of the Exchange Act will be determined
     in accordance with Rule 16b-3 under the Exchange Act.

     11.  Transfer Restrictions.  Options granted to such Participant under this
          ---------------------
Plan are exercisable only by the Participant and are not assignable or
transferable, except by will or the laws of descent and distribution.

     12.  Adjustments.  In the event of any stock split, reverse stock split,
          -----------
stock dividend, recapitalization, combination, reclassification, reorganization,
merger, combination, consolidation, exchange of Common Stock or spinoff or other
distribution of Company assets to stockholders (other than normal cash
dividends), the Committee may, in such manner and to such extent, if any, as it
deems appropriate and equitable, authorize such adjustments with respect to (a)
the aggregate number and kind of shares for which Options may be granted under
this Plan, (b) the number and kind of shares covered by outstanding Options, and
(c) the per share exercise price of outstanding Options.

     13.  Change in Control.  In connection with any merger or consolidation of
          -----------------
the Company with or into another entity in which the Company is not the
surviving corporation or as a result of which the Common Stock ceases or will
cease to be publicly traded, the Committee may, but shall not be required to,
authorize the termination of all outstanding Options upon the consummation of
such merger or consolidation. However, as a condition to such termination, all
restrictions on the exercisability of such Options (i.e., vesting provisions)
shall be eliminated and the holders thereof shall be given at least twenty (20)
days prior to such termination to exercise their Options without regard to any
such restrictions.

                                      -5-


     14.  Amendment of this Plan.  The Board may amend this Plan at any time.
          ----------------------
However, no such amendment may adversely affect the rights of any Participant
with respect to any outstanding Option without the Participant's consent.

     15.  Tax Withholding.  The Company shall have the right to take such
          ---------------
actions as may be necessary to satisfy its tax withholding obligations arising
because of the operation of this Plan.

     16.  No Additional Rights.
          --------------------

          (a)  Neither the adoption of this Plan nor the granting of any Option
     shall (i) affect or restrict in any way the power of the Company to
     undertake any corporate action otherwise permitted under applicable law,
     (ii) confer upon any Participant the right to continue performing services
     for the Company, or (iii) interfere in any way with the right of the
     Company to terminate the services of any Participant at any time, with or
     without cause, subject to such other contractual obligations which may
     exist.

          (b)  No Participant shall have any rights as a stockholder with
     respect to any shares covered by an Option granted to the Participant until
     the date a certificate for such shares has been issued to the Participant
     following the exercise of the Option.

     17.  Securities Law Restrictions.
          ---------------------------

          (a)  No shares of Common Stock shall be issued under this Plan unless
     the Committee shall be satisfied that the issuance will be in compliance
     with applicable federal and state securities laws, as well as the
     requirements of any stock exchange or quotation system upon which the
     Common Stock is listed or quoted.

          (b)  The Committee may require certain investment or other
     representations and undertakings by the person exercising an Option in
     order to comply with applicable law.

          (c)  Certificates for shares of Common Stock delivered under this Plan
     may be subject to such restrictions as the Committee may deem advisable.
     The Committee may cause a legend to be placed on the certificates to refer
     to these restrictions.

     18.  Indemnification.
          ---------------

          (a)  To the maximum extent permitted by law, the Company shall
     indemnify each member of the Committee and of the Board, as well as any
     other employee of the Company with duties under this Plan, against expenses
     and liabilities (including any amount paid in settlement) reasonably
     incurred by the individual in connection with any claims against the
     individual by reason of the performance of the individual's duties

                                      -6-


     under this Plan, unless the losses are due to the individual's gross
     negligence or lack of good faith.

          (b)  The Company will have the right to select counsel and to control
     the prosecution or defense of the suit.

          (c)  In the event that more than one person who is entitled to
     indemnification is subject to the same claim, all such persons shall be
     represented by a single counsel, unless such counsel advises the Company in
     writing that he or she cannot represent all such persons under applicable
     rules of professional responsibility.

          (d)  The Company will not be required to indemnify any person for any
     amount incurred through any settlement unless the Company consents in
     writing to the settlement.

     19.  Governing Law.  This Plan and all actions taken thereunder shall be
          -------------
governed by and construed in accordance with the laws of the State of Delaware.
