Section 5.    Stock Available for Awards
              --------------------------

       (a)  Subject to adjustment under subsection (b) below, Awards may be made
under the Plan for up to 1,200,000 shares of Common Stock. If any Award in
respect of shares of Common Stock expires or is terminated unexercised or is
forfeited for any reason or settled in a manner that results in fewer shares
outstanding than were initially awarded, the shares subject to such Award or so
surrendered, as the case may be, to the extent of such expiration, termination,
forfeiture or decrease, shall again be available for award under the Plan,
subject, however, in the case of Incentive Stock Options, to any limitation
required under the Code. Shares issued under the Plan may consist in whole or in
part of authorized but unissued shares or treasury shares.

       (b)  In the event that the Board, in its sole discretion, determines that
any stock dividend, extraordinary cash dividend, recapitalization,
reorganization, merger, consolidation, split-up, spin-off, combination or other
similar transaction affects the Common Stock such that an adjustment is required
in order to preserve the benefits or potential benefits intended to be made
available under the Plan, then the Board, subject, in the case of Incentive
Stock Options, to any limitation required under the Code, shall equitably adjust
any or all of (i) the number and kind of shares in respect of which Awards may
be made under the Plan, (ii) the number and kind of shares subject to
outstanding Awards, and (iii) the award, exercise or conversion price with
respect to any of the foregoing, and if considered appropriate, the Board may
make provision for a cash payment with respect to an outstanding Award, provided
that the number of shares subject to any Award shall always be a whole number.

       (c)  The Board may grant Awards under the Plan in substitution for stock
and stock based awards held by employees of another corporation who concurrently
become employees of the Company as a result of a merger or consolidation of the
employing corporation with the Company or a Subsidiary or the acquisition by the
Company or a subsidiary of property or stock of the employing corporation. The
substitute Awards shall be granted on such terms and conditions as the Board
considers appropriate in the circumstances, notwithstanding any limitations on
Options set forth in Section 6.

Section 6.    Stock Options
              -------------

       (a)  General.
            -------

            (i)    Subject to the provisions of the Plan, the Board may award
       Incentive Stock Options and Nonstatutory Stock Options, and determine the
       number of shares to be covered by each Option, the option price therefor
       and the conditions and limitations applicable to the exercise of the
       Option. The terms and conditions of Incentive Stock Options shall be
       subject to and comply with Section 422 of the Code, or any successor
       provision, and any regulations thereunder. Subject to adjustment as
       provided in Subsection 5(b) above, the maximum number of shares with
       respect to which Options may be granted to any employee under the Plan
       shall not exceed 800,000 shares of Common Stock during any two
       consecutive calendar year period. For purposes of calculating such
       maximum number, (a) an Option shall continue to be treated as outstanding
       notwithstanding its repricing, cancellation or expiration and (b) the
       repricing of an outstanding Option or the issuance of a new Option in
       substitution for a cancelled Option shall be deemed to constitute the
       grant of a new additional Option separate from the original grant of the
       Option that is repriced or cancelled.

                                       3
<PAGE>

            (ii)   The Board shall establish the exercise price at the time each
       option is awarded. In the case of Incentive Stock options, such price
       shall not be less than 100% of the Fair Market Value of the Common Stock
       on the date of award.

            (iii)  Each Option shall be exercisable at such times and subject to
       such terms and conditions as the Board may specify in the applicable
       Award or thereafter. The Board may impose such conditions with respect to
       the exercise of options, including conditions relating to applicable
       federal or state securities laws, as it considers necessary or advisable.

            (iv)   Options granted under the Plan may provide for the payment of
       the exercise price by delivery of cash or check in an amount equal to the
       exercise price of such options or, to the extent permitted by the Board
       at or after the award of the option, by (A) delivery of vested shares of
       Common Stock owned by the optionee for at least six months (or such
       shorter period as is approved by the Board), valued at their Fair Market
       Value, (B) delivery of a promissory note of the optionee to the Company
       on terms determined by the Board, (C) delivery of an irrevocable
       undertaking by a broker to deliver promptly to the Company sufficient
       funds to pay the exercise price or delivery of irrevocable instructions
       to a broker to deliver promptly to the Company cash or a check sufficient
       to pay the exercise price, (D) payment of such other lawful consideration
       as the Board may determine, or (E) any combination of the foregoing.

            (v)    The Board may provide for the automatic award of an option
       upon the delivery of shares to the Company in payment of the exercise
       price of an option for up to the number of shares so delivered.

            (vi)   The Board may at any time accelerate the time at which all or
       any part of an Option may be exercised.

       (b)  Incentive Stock Options.
            -----------------------

            Options granted under the Plan which are intended to be Incentive
       Stock options shall be subject to the following additional terms and
       conditions:

            (i)    All Incentive Stock Options granted under the Plan shall, at
       the time of grant, be specifically designated as such in the option
       agreement covering such Incentive Stock Options. The option exercise
       period shall not exceed ten years from the date of grant.

            (ii)   If any employee to whom an Incentive Stock Option is to be
       granted under the Plan is, at the time of the grant of such option, the
       owner of stock possessing more than 10% of the total combined voting
       power of all classes of stock of the Company (after taking into account
       the attribution of stock ownership rule of Section 424(b) and of the
       Code), then the following special provisions shall be applicable to the
       Incentive Stock Option granted to such individual:

                   (x) The purchase price per share of the Common Stock subject
            to such Incentive Stock Option shall not be less than 110% of the
            Fair Market Value of one share of Common Stock at the time of grant;
            and

                                       4
<PAGE>

                   (y) The option exercise period shall not exceed five years
            from the date of grant.

            (iii)  For so long as the Code shall so provide, options granted to
       any employee under the Plan (and any other incentive stock option plans
       of the Company) which are intended to constitute Incentive Stock Options
       shall not constitute Incentive Stock Options to the extent that such
       options, in the aggregate, become exercisable for the first time in any
       one calendar year for shares of Common Stock with an aggregate Fair
       Market Value (determined as of the respective date or dates of grant) of
       more than $100,000.

            (iv)   No Incentive Stock Option may be exercised unless, at the
       time of such exercise, the Participant is, and has been continuously
       since the date of grant of his or her option, employed by the Company,
       except that:

                   (x) an Incentive Stock Option may be exercised within the
            period of 90 days after the date the Participant ceases to be an
            employee of the Company (or within such lesser period as may be
            specified in the applicable option agreement), provided, that the
            agreement with respect to such Option may designate a longer
            exercise period and that the exercise after such 90-day period shall
            be treated as the exercise of a Nonstatutory Stock option under the
            Plan;

                   (y) if the Participant dies while in the employ of the
            Company, or within 90 days after the Participant ceases to be such
            an employee, the Incentive Stock Option may be exercised by the
            Participant's Designated Beneficiary within the period of one year
            after the date of death (or within such lesser period as may be
            specified in the applicable Option agreement); and

                   (z) if the Participant becomes disabled (within the meaning
            of Section 22(e)(3) of the Code or any successor provision thereto)
            while in the employ of the Company, the Incentive Stock option may
            be exercised within the period of one year after the date of
            disability (or within such lesser period as may be specified in the
            option agreement).

For all purposes of the Plan and any Option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Income Tax Regulations (or any successor regulations).  Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.

Section 7.    Stock Appreciation Rights
              -------------------------

       (a)  The Board may grant Stock Appreciation Rights entitling recipients
on exercise of the SAR to receive an amount, in cash or Stock or a combination
thereof (such form to be determined by the Board), determined in whole or in
part by reference to appreciation in the Fair Market Value of the Stock between
the date of the Award and the exercise of the Award. A Stock Appreciation Right
shall entitle the Participant to receive, with respect to each share of Stock as
to which the SAR is exercised, the excess of the share's Fair Market Value on
the date of exercise over its Fair Market Value on the date the SAR was granted.
The Board may also grant Stock Appreciation Rights that provide that, following
a change in control of the Company

                                       5
<PAGE>

(as defined by the Board at the time of the Award), the holder of such SAR will
be entitled to receive, with respect to each share of Stock subject to the SAR,
an amount equal to the excess of a specified value (which may include an average
of values) for a share of Stock during a period preceding such change in control
over the Fair Market Value of a share of Stock on the date the SAR was granted.

       (b)  Stock Appreciation Rights may be granted in tandem with, or
independently of, options granted under the Plan. A Stock Appreciation Right
granted in tandem with an option which is not an Incentive Stock option may be
granted either at or after the time the Option is granted. A Stock Appreciation
Right granted in tandem with an Incentive Stock option may be granted only at
the time the Option is granted.

       (c)  When Stock Appreciation Rights are granted in tandem with Options,
the following provisions will apply:

            (i)    The Stock Appreciation Right will be exercisable only at such
       time or times, and to the extent, that the related option is exercisable
       and will be exercisable in accordance with the procedure required for
       exercise of the related Option.

            (ii)   The Stock Appreciation Right will terminate and no longer be
       exercisable upon the termination or exercise of the related Option,
       except that a Stock Appreciation Right granted with respect to less than
       the full number of shares covered by an option will not be reduced until
       the number of shares as to which the related option has been exercised or
       has terminated exceeds the number of shares not covered by the Stock
       Appreciation Right.

            (iii)  The Option will terminate and no longer be exercisable upon
       the exercise of the related Stock Appreciation Right.

            (iv)   The Stock Appreciation Right will be transferable only with
       the related Option.

            (v)    A Stock Appreciation Right granted in tandem with an
       Incentive Stock Option may be exercised only when the market price of the
       Stock subject to the option exceeds the exercise price of such option.

       (d)  A Stock Appreciation Right not granted in tandem with an option will
become exercisable at such time or times, and on such conditions, as the Board
may specify.

       (e)  The Board may at any time accelerate the time at which all or any
part of the SAR may be exercised.

Section 8.    Performance Shares
              ------------------

       (a)  The Board may make Performance Share Awards entitling recipients to
acquire shares of Stock upon the attainment of specified performance goals. The
Board may make Performance Share Awards independent of or in connection with the
granting of any other Award under the Plan. The Board in its sole discretion
shall determine the performance goals applicable under each such Award, the
periods during which performance is to be measured, and

                                       6
<PAGE>

all other limitations and conditions applicable to the awarded Performance
Shares; provided, however, that the Board may rely on the performance goals and
other standards applicable to other performance plans of the Company in setting
the standards for Performance Share Awards under the Plan.

       (b)  Performance Share Awards and all rights with respect to such Awards
may not be sold, assigned, transferred, pledged or otherwise encumbered.

       (c)  A Participant receiving a Performance Share Award shall have the
rights of a stockholder only as to shares actually received by the Participant
under the Plan and not with respect to shares subject to an Award but not
actually received by the Participant. A Participant shall be entitled to receive
a stock certificate evidencing the acquisition of shares of Stock under a
Performance Share Award only upon satisfaction of all conditions specified in
the agreement evidencing the Performance Share Award.

       (d)  The Board may at any time accelerate or waive any or all of the
goals, restrictions or conditions imposed under any Performance Share Award.

Section 9.    Restricted and Unrestricted Stock
              ---------------------------------

       (a)  The Board may grant Restricted Stock Awards entitling recipients to
acquire shares of Stock, subject to the right of the Company to repurchase all
or part of such shares at their purchase price (or to require forfeiture of such
shares if purchased at no cost) from the recipient in the event that conditions
specified by the Board in the applicable Award are not satisfied prior to the
end of the applicable Restricted Period or Restricted Periods established by the
Board for such Award. Conditions for repurchase (or forfeiture) may be based on
continuing employment or service or achievement of pre-established performance
or other goals and objectives.

       (b)  Shares of Restricted Stock may not be sold, assigned, transferred,
pledged or otherwise encumbered, except as permitted by the Board, during the
applicable Restricted Period. Shares of Restricted Stock shall be evidenced in
such manner as the Board may determine. Any certificates issued in respect of
shares of Restricted Stock shall be registered in the name of the Participant
and, unless otherwise determined by the Board, deposited by the Participant,
together with a stock power endorsed in blank, with the Company (or its
designee). At the expiration of the Restricted Period, the Company (or such
designee) shall deliver such certificates to the Participant or if the
Participant has died, to the Participant's Designated Beneficiary.

       (c)  The Board may, in its sole discretion, grant (or sell at a purchase
price determined by the Board, which shall not be lower than 85% of Fair Market
Value on the date of sale) to Participants shares of Stock free of any
restrictions under the Plan ("Unrestricted Stock").

       (d)  The purchase price for each share of Restricted Stock and
Unrestricted Stock shall be determined by the Board of Directors and may not be
less than the par value of the Common Stock. Such purchase price may be paid in
the form of past services or such other lawful consideration as is determined by
the Board.

                                       7
<PAGE>

       (e)  The Board may at any time accelerate the expiration of the
Restricted Period applicable to all, or any particular, outstanding shares of
Restricted Stock.

Section 10.    General Provisions Applicable to Awards
               ---------------------------------------

       (a)  Applicability of Rule 16b-3. Those provisions of the Plan which make
an express reference to Rule 16b-3 shall apply to the Company only at such time
as the Company's Common Stock is registered under the Securities Exchange Act of
1934, or any successor provision, and then only to Reporting Persons.

       (b)  Documentation.  Each Award under the Plan shall be evidenced by an
instrument delivered to the Participant specifying the terms and conditions
thereof and containing such other terms and conditions not inconsistent with the
provisions of the Plan as the Board considers necessary or advisable. Such
instruments may be in the form of agreements to be executed by both the Company
and the Participant, or certificates, letters or similar documents, acceptance
of which will evidence agreement to the terms thereof and of this Plan.

       (c)  Board Discretion.  Each type of Award may be made alone, in addition
to or in relation to any other type of Award. The terms of each type of Award
need not be identical, and the Board need not treat Participants uniformly.
Except as otherwise provided by the Plan or a particular Award, any
determination with respect to an Award may be made by the Board at the time of
award or at any time thereafter.

       (d)  Termination of Status.  Subject to the provisions of Section
6(b)(iv), the Committee shall determine the effect on an Award of the
disability, death, retirement, authorized leave of absence or other termination
of employment or other status of a Participant and the extent to which, and the
period during which, the Participant's legal representative, guardian or
Designated Beneficiary may exercise rights under such Award.

       (e)  Mergers, Etc.  In the event of a consolidation, merger or other
reorganization in which all of the outstanding shares of Common Stock are
exchanged for securities, cash or other property of any other corporation or
business entity (an "Acquisition") or in the event of a liquidation of the
Company, the Board of Directors of the Company, or the board of directors of any
corporation assuming the obligations of the Company, may, in its discretion,
take any one or more of the following actions as to outstanding Awards: (i)
provide that such Awards shall be assumed, or substantially equivalent Awards
shall be substituted, by the acquiring or succeeding corporation (or an
affiliate thereof) on such terms as the Board determines to be appropriate, (ii)
upon written notice to Participants, provide that all unexercised Options or
SARs will terminate immediately prior to the consummation of such transaction
unless exercised by the Participant within a specified period following the date
of such notice, (iii) in the event of an Acquisition under the terms of which
holders of the Common Stock of the Company will receive upon consummation
thereof a cash payment for each share surrendered in the Acquisition (the
"Acquisition Price"), make or provide for a cash payment to Participants equal
to the difference between (A) the Acquisition Price times the number of shares
of Common Stock subject to outstanding Options or SARs (to the extent then
exercisable and to the extent the exercise price does not exceed the Acquisition
Price) and (B) the aggregate exercise price of all such outstanding options or
SARs in exchange for the termination of such Options and SARs, and

                                       8
<PAGE>

(iv) provide that all or any outstanding Awards shall become exercisable or
realizable in full prior to the effective date of such Acquisition.

       (f)  Withholding.  The Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in respect of Awards under the Plan no later than the date of the
event creating the tax liability. In the Board's discretion, and subject to such
conditions as the Board may establish, such tax obligations may be paid in whole
or in part in vested shares of Common Stock, including vested shares retained
from the Award creating the tax obligation, valued at their Fair Market Value;
provided, however, that the total tax withholding where shares are being used to
satisfy such tax obligations cannot exceed the Company's minimum statutory
withholding obligations (based on minimum statutory withholding rates for
federal and state tax purposes, including payroll taxes, that are applicable to
such supplemental taxable income). The Company may, to the extent permitted by
law, deduct any such tax obligations from any payment of any kind otherwise due
to the Participant.

       (g)  Foreign Nationals.  Awards may be made to Participants who are
foreign nationals or employed outside the United States on such terms and
conditions different from those specified in the Plan as the Board considers
necessary or advisable to achieve the purposes of the Plan or comply with
applicable laws.

       (h)  Amendment of Award.  The Board may amend, modify or terminate any
outstanding Award, including substituting therefor another Award of the same or
a different type, changing the date of exercise or realization and converting an
Incentive Stock Option to a Nonstatutory Stock Option, provided that the
Participant's consent to such action shall be required unless the Board
determines that the action, taking into account any related action, would not
materially and adversely affect the Participant.

       (i)  Conditions on Delivery of Stock.  The Company will not be obligated
to deliver any shares of Stock pursuant to the Plan or to remove restrictions
from shares previously delivered under the Plan (i) until all conditions of the
Award have been satisfied or removed, (ii) until, in the opinion of the
Company's counsel, all applicable federal and state laws and regulations have
been complied with, (iii) if the outstanding Stock is at the time listed on any
stock exchange, until the shares to be delivered have been listed or authorized
to be listed on such exchange upon official notice of notice of issuance, and
(iv) until all other legal matters in connection with the issuance and delivery
of such shares have been approved by the Company's counsel. If the sale of Stock
has not been registered under the Securities Act of 1933, as amended, the
Company may require, as a condition to exercise of the Award, such
representations or agreements as the Company may consider appropriate to avoid
violation of such Act and may require that the certificates evidencing such
Stock bear an appropriate legend restricting transfer.

Section 11.    Miscellaneous
               -------------
