        5.1 OPTION AGREEMENT. Each Option granted pursuant to this Plan shall be
evidenced by an Option Agreement which shall specify the number of shares
subject thereto, the vesting provisions relating to such Option, and the

held by the Optionee for at least six (6) months, which surrendered shares shall
be valued at Fair Market Value as of the date of such exercise; (d) the
Optionee's promissory



                                       4

cancellation of indebtedness of the Company to the Optionee; (f) the waiver of
compensation due or accrued to the Optionee for services rendered; (g) provided
that a public market for the Common Stock exists, a "same day sale" commitment
from the Optionee and an NASD Dealer whereby the Optionee irrevocably elects to
exercise the Option and to sell a portion of the shares so purchased to pay for
the Exercise Price and whereby the NASD Dealer irrevocably commits upon receipt
of such shares to forward the Exercise Price directly to the Company; (h)
provided that a public market for the Common Stock exists, a "margin" commitment
from the Optionee and an NASD Dealer whereby the Optionee irrevocably elects to
exercise the Option and to pledge the shares so purchased to the NASD Dealer in
a margin account as security for a loan from the NASD Dealer in the amount of
the Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt
of such shares to forward the Exercise Price directly to the Company; or (i) any
combination of the foregoing methods of payment or any other consideration or
method of payment as shall be permitted by applicable corporate law.

        5.4 TERM AND TERMINATION OF OPTIONS. The term and provisions for
termination of each Option shall be as fixed by the Administrator, but no Option
may be exercisable more than ten (10) years after the date it is granted.

        5.5 VESTING AND EXERCISE OF OPTIONS. Each Option shall vest and become
exercisable in one or more installments at such time or times and subject to
such conditions, including without limitation the achievement of specified
performance goals or objectives, as shall be determined by the Administrator.

an Optionee or a transferee of an Optionee except (i) by will or the laws of
descent and distribution; or (ii) with the prior written consent of the Company,
which consent may be withheld by the Company in the Company's sole discretion.

        5.7 RIGHTS AS STOCKHOLDER. An Optionee or permitted transferee of an
Option shall have no rights or privileges as a stockholder with respect to any
shares covered by an Option until such Option has been duly exercised and
certificates representing shares purchased upon such exercise have been issued
to such person.

        5.8 RESTRICTIONS ON UNDERLYING SHARES OF COMMON STOCK. Shares of Common
Stock issued pursuant to the exercise of an Option may be sold, assigned,
transferred, pledged and otherwise encumbered or disposed of, except as
specifically provided in the Option Agreement.

                               RIGHTS TO PURCHASE

        6.1 NATURE OF RIGHT TO PURCHASE AND PURCHASE PRICE. A Right to Purchase
granted to an Offeree entitles the Offeree to purchase, for a Purchase Price
determined by the Administrator, shares of Common Stock subject to such terms,
restrictions and conditions as the Administrator may determine at the time of
grant ("Restricted Stock"). Such conditions may include, but are not limited to,
continued employment or the achievement of specified performance goals or
objectives. The

   6

Purchase Price per share of Common Stock covered by each Right to Purchase shall
be determined by the Administrator.

        6.2 ACCEPTANCE OF RIGHT TO PURCHASE. An Offeree shall have no rights
with respect to the Restricted Stock subject to a Right to Purchase unless the
Offeree shall have accepted the Right to Purchase within ten (10) days (or such
longer or shorter period as the Administrator may specify) following the grant
of the Right to Purchase by making payment of the full Purchase Price to the
Company in the manner set forth in Section 6.3 hereof and by executing and
delivering to the Company a Stock Purchase Agreement. Each Stock Purchase
Agreement shall be in such form, and shall set forth the Purchase Price and such
other terms, conditions and restrictions of the Restricted Stock, not
inconsistent with the provisions of this Plan, as the Administrator shall, from
time to time, deem desirable. Each Stock Purchase Agreement may be different
from each other Stock Purchase Agreement.

        6.3 PAYMENT OF PURCHASE PRICE. Subject to any legal restrictions,
payment of the Purchase Price upon acceptance of a Right to Purchase Restricted
Stock may be made, in the discretion of the Administrator, by: (a) cash; (b)
check; (c) the surrender of shares of Common Stock owned by the Offeree that
have been held by the Offeree for at least six (6) months, which surrendered
shares shall be valued at Fair Market Value as of the date of such exercise; (d)
the Offeree's promissory note in a form and on terms acceptable to the
Administrator; (e) the cancellation of indebtedness of the Company to the
Offeree; (f) the waiver of compensation due or accrued to the Offeree for
services rendered; or (g) any combination of the foregoing methods of payment or
any other consideration or method of payment as shall be permitted by applicable
corporate law.

        6.4 RIGHTS AS A STOCKHOLDER. Upon complying with the provisions of
Section 6.2 hereof, an Offeree shall have the rights of a stockholder with
respect to the Restricted Stock purchased pursuant to the Right to Purchase,
including voting and dividend rights, subject to the terms, restrictions and
conditions as are set forth in the Stock Purchase Agreement. Unless the
Administrator shall determine otherwise, certificates evidencing shares of
Restricted Stock shall remain in the possession of the Company until such shares
have vested in accordance with the terms of the Stock Purchase Agreement.

        6.5 RESTRICTIONS AND REPURCHASE RIGHT. Vested Shares of Restricted Stock
may be sold, assigned, transferred, pledged and otherwise encumbered or disposed
of, except as specifically provided in the Stock Purchase Agreement. In the
event of termination of a Participant's employment, service as a director of the
Company or Service Provider status for any reason whatsoever (including death or
disability), the Stock Purchase Agreement may provide, in the discretion of the
Administrator, that the Company shall have the right, exercisable at the
discretion of the Administrator, to repurchase, at the original Purchase Price,
any shares of Restricted Stock which have not vested as of the date of
termination.

        6.6 VESTING OF RESTRICTED STOCK. The Stock Purchase Agreement shall
specify, if applicable as determined by the Administrator in its discretion, the
date or dates, the performance goals or objectives which must be achieved, and
any other conditions on which the Restricted Stock may vest.



                                       6

        6.7 DIVIDENDS. If payment for shares of Restricted Stock is made by
promissory note, any cash dividends paid with respect to the Restricted Stock
may be applied, in the discretion of the Administrator, to repayment of such
note.

        6.8 NONASSIGNABILITY OF RIGHTS. Rights to Purchase shall not be
transferable by a Participant or a transferee of a Participant except (i) by
will or the laws of descent and distribution; or (ii) with the prior written
consent of the Company, which consent may be withheld by the Company in the
Company's sole discretion.

                                   ARTICLE 8.

                                CHANGE IN CONTROL

        8.1 CHANGE IN CONTROL. In order to preserve a Participant's rights in

the exercise or realization of all outstanding Options, Rights to Purchase and
Restricted Stock shall automatically accelerate immediately prior to the
consummation of such Change in Control, and (ii) with respect to Options and
Rights to Purchase, the Administrator in its discretion may, at any time an
Option or Right to Purchase is granted, or at any time thereafter, take one or
more of the following actions: (A) provide for the purchase or exchange of each
Option or Right to Purchase for an amount of cash or other property having a
value equal to the difference, or spread, between (x) the value of the cash or
other property that the Participant would have received pursuant to such Change
in Control transaction in exchange for the shares issuable upon exercise of the
Option or Right to Purchase had the Option or Right to Purchase been exercised
immediately prior to such Change in Control transaction and (y) the Exercise

successor corporation, with appropriate adjustments as to the number and kind of
shares and Exercise Prices, in which event the Plan and such Options and Rights
to Purchase, or the new options and rights to purchase substituted therefor,
shall continue in the manner and under the terms so provided, or (D) make such
other provision as the Administrator may consider equitable. If the
Administrator does not take any of the forgoing actions, all Options and Rights
to Purchase shall terminate upon the consummation of the Change in Control and
the Administrator shall cause written notice of the proposed transaction to be
given to all Participants not less than thirty (30) days prior to the
anticipated effective date of the proposed transaction.

                      AMENDMENT AND TERMINATION OF THE PLAN

        9.1 AMENDMENTS. The Board may from time to time alter, amend, suspend or
terminate the Plan in such respects as the Board may deem advisable. No such
alteration, amendment, suspension or termination shall be made which shall
substantially affect or impair the rights of any Participant under an
outstanding Option Agreement or Stock Purchase Agreement without such
Participant's consent. The Board may alter or amend the Plan to comply with
requirements under the Code relating to Options which give Optionees more
favorable tax treatment than that applicable to Options granted under this Plan
as of the date of its adoption, or to comply with provisions under applicable
securities laws, including without limitation, Rule 16b-3 under the Securities
Exchange Act of 1934, as amended. Upon any such alteration or amendment, any
outstanding Option granted hereunder may, if the Administrator so determines and
if permitted by applicable law, be subject to the more favorable tax treatment
afforded to an Optionee pursuant to such terms and conditions.

        9.2 PLAN TERMINATION. Unless the Plan shall theretofore have been
terminated, the Plan shall terminate on the tenth (10th) anniversary of the
Effective Date and no Options or Rights to Purchase may be granted under the
Plan thereafter, but Option Agreements, Stock Purchase Agreements and Rights to
Purchase then outstanding shall continue in effect in accordance with their
respective terms.

                                 TAX WITHHOLDING

        10.1 WITHHOLDING. The Company shall have the power to withhold, or
require a Participant to remit to the Company, an amount sufficient to satisfy
any applicable Federal, state, and local tax withholding requirements with
respect to any Options exercised or Restricted Stock issued under the Plan. To
the extent permissible under applicable tax, securities and other laws, the
Administrator may, in its sole discretion and upon such terms and conditions as
it may deem appropriate, permit a Participant to satisfy his or her obligation
to pay any such tax, in whole or in part, up to an amount determined on the
basis of the highest marginal tax rate applicable to such Participant, by (a)
directing the Company to apply shares of Common Stock to which the Participant
is entitled as a result of the exercise of an Option or as a result of the
purchase of or lapse of restrictions on Restricted Stock or (b) delivering to
the Company shares of Common Stock owned by the Participant. The shares of
Common Stock so applied or delivered in satisfaction of the Participant's tax
withholding obligation shall be valued at their Fair Market Value as of the date
of measurement of the amount of income subject to withholding.

        11.2 NO ENLARGEMENT OF EMPLOYEE RIGHTS. This Plan is strictly a
voluntary undertaking on the part of the Company and shall not be deemed to
constitute a contract between the Company and any Participant to be
consideration for, or an inducement to, or a condition of, the employment of any
Participant. Nothing contained in the Plan shall be deemed to give the right to
any Participant to be retained as an employee of the Company or any Affiliated
Company or to limit the right of the Company or any Affiliated Company to
discharge any Participant at any time.

        11.3 APPLICATION OF FUNDS. The proceeds received by the Company from the
sale of Common Stock pursuant to Option Agreements and Stock Purchase
