     5.   ELIGIBILITY AND AWARD.

          A.   Terms and Conditions of Options. The Board of Directors shall
determine, at any time and from time to time, (i) any Eligible Person to whom
the award of an Option or SAR may further the purposes of this Plan in the view
of the Board of Directors, (ii) whether any Option to be awarded to an Eligible
Person shall be intended as an ISO or as a NQSO, the number of shares of
Incentive Stock to be covered by such Option or a SAR, the Exercise Price of
such Option or SAR, whether such Option contains a SAR and all other terms and
conditions of such Option, (iii) the Fair Market Value on the date of grant of
the Option or SAR and (iv) the terms and conditions of the Stock Option
Agreement to evidence such Option or SAR, including the restrictions, if any,
applicable to the shares of Incentive Stock that may be acquired upon exercise
of any portion of such Option. The Board of Directors may delegate to the
appropriate officer or officers of the Corporation the authority to prepare,
execute and deliver any Stock Option Agreement evidencing any Option or SAR
granted under this Plan; provided, however, that any such Stock Option Agreement
shall be consistent with the terms and conditions of this Plan.

          B.   Terms and Conditions of ISO. For any Option intended to qualify
as an ISO, in whole or in part, (i) the Eligible Person shall then be an
employee of the Corporation or a Parent or Subsidiary, as provided in the Code,
(ii) the term during which such Option shall be in effect shall not be greater
than ten (10) years (provided, however, that the term shall not be greater than
five (5) years for any Option granted to a Controlling Participant), (iii) the
Exercise Price shall not be less than one hundred percent (100%) of the Fair
Market Value on the date that such Option is granted (provided, however, that,
if an ISO shall be granted to a Controlling Participant, the Exercise Price
shall not be less than one hundred ten percent (110%) of the Fair Market Value
on the date that such Option is granted) and (iv) such Option is exercisable
only by the Participant during his or her lifetime and shall be nontransferable
by the Participant unless the Stock Option Agreement permits such Option to be
transferred by will or the laws of descent and distribution.

          C.   Notice of Option Grant. As soon as practicable after the Board of
Directors determines to award an Option or SAR pursuant to 5A hereof, the
appropriate officer or officers of the Corporation shall give notice (written or
oral) to such effect to each Eligible Person designated to be awarded an Option
or SAR, which notice shall be accompanied by a copy or copies of the Stock
Option Agreement to be executed by such Eligible Person.

          D.   Execution of Stock Option Agreement. Upon receipt of the notice
specified in 5C hereof, an Eligible Person shall have an Option or SAR, and
shall thereby become and be a Participant, only after the due execution and
delivery by such Eligible Person and the Corporation of a Stock Option Agreement
(in such form and number as the officer or officers of the Corporation shall
direct) by such date and time as shall be specified in such notice (unless
waived by the Corporation).

          E.   Assumption of Option. In the event that the Corporation or any
Parent or Subsidiary assumes an option granted by another entity, which option
is to be covered by this Plan and upon the exercise of which shares of Incentive
Stock are to be issued, the terms and conditions of such option shall remain
unchanged (except the exercise price and the number and


                                      -4-

<PAGE>   5

nature of shares issuable upon exercise thereof, which shall be adjusted
appropriately in accordance with the Code, and references to such other entity,
which shall be deemed to refer to the Corporation). In the event that the Board
of Directors elects to grant an Option or SAR under this Plan to replace an
option or SAR granted by another entity (rather than assume such option or SAR),
the holder of such option or SAR shall be eligible to receive such replacement
Option or SAR, which may be granted with a similarly-adjusted Exercise Price.

     6.   Exercise and Termination of Options.

          A.   Exercise of Option. An Option of a Participant may be exercised
during the period such Option is in effect and as set forth herein and in the
Stock Option Agreement, and only if compliance with all applicable Federal and
state securities laws can be effected. An Option may be exercised only by (i)
the Participant's completion, execution and delivery to the Corporation of a
notice of such Participant's exercise of such Option and an "investment letter"
(if required by the Corporation) as supplied by the Corporation and (ii) the
payment to the Corporation of the aggregate Exercise Price, in accordance with
6B hereof and the Stock Option Agreement, for the shares of Incentive Stock to
be purchased pursuant to such exercise (as shall be specified by such
Participant in such notice). Except as specifically provided by a duly executed
Stock Option Agreement or unless waived by the Board of Directors, an Option or
any of the rights thereunder may be exercised by such Participant only, and may
not be transferred or assigned, voluntarily, involuntarily or by operation of
law (including, without limitation, the laws of bankruptcy, intestacy, descent
and distribution and succession).

          B.   Payment. Payment by each Participant for the shares of Incentive
Stock purchased hereunder upon the exercise of an Option shall be made by good
check or in accordance with the terms of any Stock Option Agreement executed by
such Participant.

          C.   Repurchase Right. The Board of Directors at any time or from time
to time may offer to buy out for a payment in cash or Incentive Stock all or a
portion of an outstanding Option held by a Participant, based on such terms and
conditions as the Board of Directors shall establish and communicate to the
Participant at the time that such offer is made. The Board of Directors may
provide for the surrender of all or any portion of an Option in satisfaction of
specified obligations of a Participant, including tax withholding obligations.

          D.   Tax Obligations. As a condition to the exercise of any Option or
SAR (for non-cash consideration), the Corporation shall have the right to
require that the Participant (or the recipient of any shares of Incentive Stock
or noncash consideration) remit to the Corporation or any Parent or Subsidiary
an amount calculated by the Corporation to be sufficient to satisfy applicable
Federal, state, foreign or local withholding tax requirements prior to the
delivery of any stock certificate evidencing shares of Incentive Stock or other
form of non-cash consideration; in lieu thereof, the Participant may satisfy
applicable withholding tax requirements by electing to have the Corporation
withhold from the Incentive Stock issuable upon exercise of an Option a number
of whole shares having a fair Market Value (determined on the date that the
amount of tax to be withheld is to be fixed) at least equal to the aggregate
amount required to be withheld. Whenever any payments are to be made in cash
(upon the exercise of a SAR or otherwise), the Corporation shall be entitled, in
its sole discretion, to deduct


                                      -5-

<PAGE>   6

from such payment such amount calculated by the Corporation to be sufficient to
satisfy applicable Federal, state, foreign or local withholding tax requirements
thereon.

     7.   COSTS AND EXPENSES. All costs and expenses with respect to the
adoption, implementation, interpretation and administration of this Plan shall
be borne by the Corporation; provided, however, that, except as otherwise
specifically provided in this Plan or the applicable Stock Option Agreement
between the Corporation and a Participant, the Corporation shall not be
obligated to pay any costs or expenses (including legal fees) incurred by any
Participant in connection with any Stock Option Agreement, this Plan or any
Option, SAR or Incentive Stock held by any Participant.

     8.   NO PRIOR RIGHT OF AWARD. Nothing in this Plan shall be deemed to give
any director, officer or employee of, or advisor or consultant to, the
Corporation or any Parent or Subsidiary, or such person's legal representatives
or assigns, or any other person or entity claiming under or through such person,
any contract or other right to participate in the benefits of this Plan. Nothing
in this Plan shall be construed as constituting a commitment, guarantee,
agreement or understanding of any kind or nature that the Corporation or any
Parent or Subsidiary shall continue to employ, retain or engage any individual
(whether or not a Participant). This Plan shall not affect in any way the right
of the Corporation and any Parent or Subsidiary to terminate the employment or
engagement of any individual (whether or not a Participant) at any time and for
any reason whatsoever and to remove any individual (whether or not a
Participant) from any position as a director or officer. No change of a
Participant's duties as an employee of the Corporation or any Parent or
Subsidiary shall result in a modification of the terms of any rights of such
Participant under this Plan or any Stock Option Agreement executed by such
Participant.

     9.   CHANGES IN CAPITAL STRUCTURE. Subject to any required action by the
stockholders of the Corporation and the provisions of the General Corporation
Law of the State of Delaware, the number of shares of Incentive Stock
represented by the unexercised portion of an Option or SAR and the number of
shares of Incentive Stock which has been authorized or reserved for issuance
hereunder (whether such shares are unissued, reacquired or subject to an Option
or SAR that expired, was cancelled, surrendered or terminated unexercised as to
such shares), as well as the Exercise Price under the unexercised portion of an
Option or SAR, shall be proportionately adjusted for (a) a division, combination
or reclassification of any of the shares of Common Stock of the Corporation or
(b) a dividend payable in shares of Common Stock of the Corporation.

     10.  AMENDMENT OR TERMINATION OF PLAN. Except as otherwise provided herein,
this Plan may be amended or terminated in whole or in part by the Board of
Directors (in its sole discretion), but no such action shall adversely affect or
alter any right or obligation with respect to any Option, SAR or Stock Option
Agreement then in effect, except to the extent that any such action shall be
required or desirable (in the opinion of the Corporation or its counsel) so that
any Option intended to qualify as an IS0 complies with the Code or any rule or
regulation promulgated or proposed thereunder.

     11.  BURDEN AND BENEFIT. The terms and provisions of this Plan shall be
binding upon, and shall inure to the benefit of, each Participant and such
Participant's executors and administrators, estate, heirs and personal and legal
representatives.

     12.  HEADINGS. The headings and other captions contained in this Plan are
for convenience and reference only and shall not be used in interpreting,

     13.  INTERPRETATION. Notwithstanding any provision of this Plan or any
provision of any Stock Option Agreement evidencing an Option that is intended,
in whole or in part, to qualify as an ISO, this Plan and each such Stock Option
Agreement are intended to comply with all requirements for qualification under
the Code and with any rule or regulation promulgated or proposed thereunder, and
shall be interpreted and construed in a manner which is consistent with this
Plan and each such Stock Option Agreement being so qualified. This Plan shall be
governed by, and construed in accordance with, the substantive laws of the State
of Delaware (other than rules of conflicts-of-law or choice-of-law).
