Section 4.  Shares Available for Awards

                  (a) Shares Available. Subject to adjustment as provided in
Section 4(c) of the Plan, the aggregate number of Shares that may be issued
under all Awards under the Plan shall be 3,000,000. Shares to be issued under
the Plan may be either authorized but unissued Shares or Shares acquired in the
open market or otherwise. Any Shares that are used by a Participant as full or
partial payment to the Company of the purchase price relating to an Award, or in
connection with the satisfaction of tax obligations relating to an Award, shall
again be available for granting Awards (other than Incentive Stock Options)
under the Plan. In addition, if any Shares covered by an Award or to which an
Award relates are not purchased or are forfeited, or if an Award otherwise
terminates without delivery of any Shares, then the number of Shares counted
against the aggregate number of Shares available under the Plan with respect to
such Award, to the extent of any such forfeiture or termination, shall again be
available for granting Awards under the Plan. Notwithstanding the foregoing, the
number of Shares available for granting Incentive Stock Options under the Plan
shall not exceed 3,000,000, subject to adjustment as provided in the Plan and
subject to the provisions of Section 422 or 424 of the Code or any successor
provision.

                  (b) Accounting for Awards. For purposes of this Section 4, if
an Award entitles the holder thereof to receive or purchase Shares, the number
of Shares covered by such Award or to which such Award relates shall be counted
on the date of grant of such Award against the aggregate number of Shares
available for granting Awards under the Plan.

                  (c) Adjustments. In the event that the Committee shall
determine that any dividend or other distribution (whether in the form of cash,
Shares, other securities or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee to be
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and type of Shares (or other securities or other property) that
thereafter may be made the subject of Awards, (ii) the number and type of Shares
(or other securities or other property) subject to outstanding Awards and (iii)
the purchase or exercise price with respect to any Award; provided, however,
that the number of Shares covered by any Award or to which such Award relates
shall always be a whole number.

                  (d) Award Limitations Under the Plan. No Eligible Person may
be granted any Award or Awards under the Plan, the value of which Award or
Awards is based solely on an increase in the value of the Shares after the date
of grant of such Award or Awards, for more than 1,000,000 Shares (subject to
adjustment as provided for in Section 4(c) of the Plan), in the aggregate in any
calendar year. The foregoing annual limitation specifically includes the grant
of any Award or Awards representing "qualified performance-based compensation"
within the meaning of Section 162(m) of the Code.

Section 5.  Eligibility

         Any Eligible Person shall be eligible to be designated a Participant.
In determining which Eligible Persons shall receive an Award and the terms of
any Award, the Committee may take into account the nature of the services
rendered by the respective Eligible Persons, their present and potential
contributions to the success of the Company or such other factors as the
Committee, in its discretion, shall deem relevant. Notwithstanding the
foregoing, an Incentive Stock Option may only be granted to full or part-time
employees (which term as used herein includes, without limitation, officers and
Directors who are also employees), and an Incentive Stock Option shall not be
granted to an employee of an Affiliate unless such Affiliate is also a
"subsidiary corporation" of the Company within the meaning of Section 424(f) of
the Code or any successor provision.

Section 6.  Awards

                  (a)      Options. The Committee is hereby authorized to grant
Options to Participants with the following terms and conditions and with such
additional terms and conditions not inconsistent with the provisions of the Plan
as the Committee shall determine:

                           (i)      Exercise Price. The purchase price per Share
purchasable under an Option shall be determined by the Committee; provided,
however, that such purchase price shall not be less than 100% of the Fair Market
Value of a Share on the date of grant of such Option.

                           (ii)     Option Term.  The term of each Option shall
be fixed by the Committee.

                           (iii)    Time and Method of Exercise.  The Committee
shall determine the time or times at which an Option may be exercised in whole
or in part and the method or methods by which, and the form or forms (including,
without limitation, cash, Shares, promissory notes, other securities, other
Awards or other property, or any combination thereof, having a Fair Market Value
on the exercise date equal to the relevant exercise price) in which, payment of
the exercise price with respect thereto may be made or deemed to have been made.

                           (iv)     Incentive Stock Options.  Notwithstanding
anything in the Plan to the contrary, the following additional provisions shall
apply to the grant of stock options which are intended to qualify as Incentive
Stock Options:

                                    (A) The aggregate Fair Market Value
                           (determined as of the time the option is granted) of
                           the Shares with respect to which Incentive Stock
                           Options are exercisable for the first time by any
                           participant during any calendar year (under this Plan
                           and all other plans of the Company and its
                           Affiliates) shall not exceed $100,000.

                                    (B) All Incentive Stock Options must be
                           granted within ten years from the earlier of the date
                           on which this Plan was adopted by Board of Directors
                           or the date this Plan was approved by the
                           shareholders of the Company.

<PAGE>

                                    (C) Unless sooner exercised, all Incentive
                           Stock Options shall expire and no longer be
                           exercisable no later than 10 years after the date of
                           grant; provided, however, that in the case of a grant
                           of an Incentive Stock Option to a participant who, at
                           the time such Option is granted, owns (within the
                           meaning of Section 422 of the Code) stock possessing
                           more than 10% of the total combined voting power of
                           all classes of stock of the Company or of its
                           Affiliate, such Incentive Stock Option shall expire
                           and no longer be exercisable no later than 5 years
                           from the date of grant.

                                    (D) The purchase price per Share for an
                           Incentive Stock Option shall be not less than 100% of
                           the Fair Market Value of a Share on the date of grant
                           of the Incentive Stock Option; provided, however,
                           that, in the case of the grant of an Incentive Stock
                           Option to a participant who, at the time such Option
                           is granted, owns (within the meaning of Section 422
                           of the Code) stock possessing more than 10% of the
                           total combined voting power of all classes of stock
                           of the Company or of its Affiliate, the purchase
                           price per Share purchasable under an Incentive Stock
                           Option shall be not less than 110% of the Fair Market
                           Value of a Share on the date of grant of the
                           Inventive Stock Option.

                                    (E) Any Incentive Stock Option authorized
                           under the Plan shall contain such other provisions as
                           the Committee shall deem advisable, but shall in all
                           events be consistent with and contain all provisions
                           required in order to qualify the Option as an
                           Incentive Stock Option.

                       (b) Stock Appreciation Rights. The Committee is hereby
authorized to grant Stock Appreciation Rights to Participants subject to the
terms of the Plan and any applicable Award Agreement. A Stock Appreciation Right

during a specified period before or after the date of exercise) over (ii) the
grant price of the Stock Appreciation Right as specified by the Committee, which
price shall not be less than 100% of the Fair Market Value of one Share on the
date of grant of the Stock Appreciation Right. Subject to the terms of the Plan
and any applicable Award Agreement, the grant price, term, methods of exercise,

any Stock Appreciation Right shall be as determined by the Committee. The
Committee may impose such conditions or restrictions on the exercise of any
Stock Appreciation Right as it may deem appropriate.

                       (c) Restricted Stock. The Committee is hereby authorized
to grant Restricted Stock to Participants with the following terms and
conditions and with such additional terms and conditions not inconsistent with
the provisions of the Plan as the Committee shall determine:

                           (i) Restrictions. Shares of Restricted Stock shall be
subject to such restrictions as the Committee may impose (including, without
limitation, a waiver by the Participant of the right to vote or to receive any
dividend or other right or property with respect thereto), which restrictions
may lapse separately or in combination at such time or times, in such
installments or otherwise as the Committee may deem appropriate.

                           (ii)   Stock Certificates. Any Restricted Stock
granted under the Plan shall be registered in the name of the Participant and
shall bear an appropriate legend referring to the terms, conditions and
restrictions applicable to such Restricted Stock.

                           (iii)  Forfeiture. Except as otherwise determined by
the Committee, upon termination of employment (as determined under criteria
established by the Committee) during the applicable restriction period, all
Shares of Restricted Stock subject to restriction at such time shall be
forfeited and reacquired by the Company; provided, however, that the Committee
may, when it finds that a waiver would be in the best interest of the Company,
waive in whole or in part any or all remaining restrictions with respect to
Shares of Restricted Stock.

                       (d) Performance Awards. The Committee is hereby
authorized to grant Performance Awards to Participants subject to the terms of
the Plan and any applicable Award Agreement. A Performance Award granted under
the Plan (i) may be denominated or payable in cash, Shares (including, without
limitation, Restricted Stock), other securities, other Awards or other property
and (ii) shall confer on the holder thereof the right to receive payments, in
whole or in part, upon the achievement of such performance goals during such
performance periods as the Committee shall establish. Subject to the terms of
the Plan and any applicable Award Agreement, the performance goals to be
achieved during any performance period, the length of any performance period,
the amount of any Performance Award granted, the amount of any payment or
transfer to be made pursuant to any Performance Award and any other terms and
conditions of any Performance Award shall be determined by the Committee.

                       (e) Other Stock Grants. The Committee is hereby
authorized, subject to the terms of the Plan and any applicable Award Agreement,
to grant to Participants Shares without restrictions thereon as are deemed by
the Committee to be consistent with the purpose of the Plan.

                       (f) Other Stock-Based Awards. The Committee is hereby
authorized to grant to Participants subject to the terms of the Plan and any
applicable Award Agreement, such other Awards that are denominated or payable
in, valued in whole or in part by reference to, or otherwise based on or related
to, Shares (including, without limitation, securities convertible into Shares),
as are deemed by the Committee to be consistent with the purpose of the Plan.
Shares or other securities delivered pursuant to a purchase right granted under
this Section 6(f) shall be purchased for such consideration, which may be paid
by such method or methods and in such form or forms (including, without
limitation, cash, Shares, promissory notes, other securities, other Awards or
other property or any combination thereof), as the Committee shall determine,
the value of which consideration, as established by the Committee, shall not be
less than 100% of the Fair Market Value of such Shares or other securities as of
the date such purchase right is granted.

                       (g) General

                           (i)    No Cash Consideration for Awards. Awards shall
be granted for no cash consideration or for such minimal cash consideration as
may be required by applicable law.

                           (ii)   Awards May Be Granted Separately or Together.
Awards may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with or in

                                       -7-

substitution for any other Award or any award granted under any plan of the
Company or any Affiliate other than the Plan. Awards granted in addition to or
in tandem with other Awards or in addition to or in tandem with awards granted
under any such other plan of the Company or any Affiliate may be granted either
at the same time as or at a different time from the grant of such other Awards
or awards.

                           (iii)  Forms of Payment under Awards. Subject to the
terms of the Plan and of any applicable Award Agreement, payments or transfers
to be made by the Company or an Affiliate upon the grant, exercise or payment of
an Award may be made in such form or forms as the Committee shall determine
(including, without limitation, cash, Shares, promissory notes, other
securities, other Awards or other property or any combination thereof), and may
be made in a single payment or transfer, in installments or on a deferred basis,
in each case in accordance with rules and procedures established by the
Committee. Such rules and procedures may include, without limitation, provisions
for the payment or crediting of reasonable interest on installment or deferred
payments or the grant or crediting of dividend equivalents with respect to
installment or deferred payments.

                           (iv)   Limits on Transfer of Awards. No Award (other
than Other Stock Grants) and no right under any such Award shall be transferable
by a Participant otherwise than by will or by the laws of descent and
distribution and the Company shall not be required to recognize any attempted
assignment of such rights by any participant. Each Award or right under any
Award shall be exercisable during the Participant's lifetime only by the
Participant or, if permissible under applicable law, by the Participant's
guardian or legal representative. No Award or right under any such Award may be
pledged, alienated, attached or otherwise encumbered, and any purported pledge,
alienation, attachment or encumbrance thereof shall be void and unenforceable
against the Company or any Affiliate.

                           (v)    Term of Awards. The term of each Award shall
be for such period as may be determined by the Committee; provided, however,
that in the case of an Incentive Stock Option such option shall not be
exercisable after the expiration of 10 years from the date such option is
granted.

                           (vi)   Restrictions; Securities Exchange Listing. All
Shares or other securities delivered under the Plan pursuant to any Award or the
exercise thereof shall be subject to such restrictions as the Committee may deem
advisable under the Plan, applicable federal or state securities laws and
regulatory requirements, and the Committee may cause appropriate entries to be
made or legends to be affixed to reflect such restrictions. If any securities of
the Company are traded on a securities exchange or system, the Company shall not
be required to deliver any Shares or other securities covered by an Award unless
and until such Shares or other securities have been admitted for trading on such
securities exchange or system.

Section 7.  Amendment and Termination; Adjustments

                    (a)    Amendments to the Plan. The Board may amend, alter,
suspend, discontinue or terminate the Plan at any time; provided, however, that,
notwithstanding any other provision of the Plan or any Award Agreement, without
the approval of the shareholders of the Company, no such amendment, alteration,
suspension, discontinuation or termination shall be made that, absent such
approval:

                                       -8-

<PAGE>

                           (i)    would violate the rules or regulations of the
NASDAQ National Market System or any securities exchange that are applicable to
the Company; or

                           (ii)   would cause the Company to be unable, under
the Code, to grant Incentive Stock Options under the Plan.

                      (b)  Amendments to Awards. The Committee may waive any
conditions of or rights of the Company under any outstanding Award,
prospectively or retroactively. Except as otherwise provided herein or in the
Award Agreement, the Committee may not amend, alter, suspend, discontinue or
terminate any outstanding Award, prospectively or retroactively, if such action
would adversely affect the rights of the holder of such Award, without the
consent of the Participant or holder or beneficiary thereof.

                      (c)  Correction of Defects, Omissions and Inconsistencies.
The Committee may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem desirable to carry the Plan into effect.

Section 8. Income Tax Withholding

         In order to comply with all applicable federal or state income tax laws
or regulations, the Company may take such action as it deems appropriate to
ensure that all applicable federal or state payroll, withholding, income or
other taxes, which are the sole and absolute responsibility of a Participant,
are withheld or collected from such Participant. In order to assist a
Participant in paying all or a portion of the federal and state taxes to be
withheld or collected upon exercise or receipt of (or the lapse of restrictions
relating to) an Award, the Committee, in its discretion and subject to such
additional terms and conditions as it may adopt, may permit the Participant to
satisfy such tax obligation by (i) electing to have the Company withhold a
portion of the Shares otherwise to be delivered upon exercise or receipt of (or
the lapse of restrictions relating to) such Award with a Fair Market Value equal
to the amount of such taxes or (ii) delivering to the Company Shares other than
Shares issuable upon exercise or receipt of (or the lapse of restrictions
relating to) such Award with a Fair Market Value equal to the amount of such
taxes. The election, if any, must be made on or before the date that the amount
of tax to be withheld is determined.

Section 9. General Provisions

                      (a)  No Rights to Awards. No Eligible Person, Participant
or other Person shall have any claim to be granted any Award under the Plan, and
there is no obligation for uniformity of treatment of Eligible Persons,
Participants or holders or beneficiaries of Awards under the Plan. The terms and
conditions of Awards need not be the same with respect to any Participant or
with respect to different Participants.

                      (b)  Award Agreements. No Participant will have rights
under an Award granted to such Participant unless and until an Award Agreement
shall have been duly executed on behalf of the Company and, if requested by the
Company, signed by the Participant.

                      (c)  Plan Provisions Control. In the event that any
provision of an Award Agreement conflicts with or is inconsistent in any respect
with the terms of the Plan as set forth herein or subsequently amended, the
terms of the Plan shall control.

                                       -9-

<PAGE>

                  (d) No Limit on Other Compensation Arrangements. Nothing
contained in the Plan shall prevent the Company or any Affiliate from adopting
or continuing in effect other or additional compensation arrangements, and such
arrangements may be either generally applicable or applicable only in specific
cases.

                  (e) No Right to Employment. The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Affiliate, nor will it affect in any way the right of the Company
or an Affiliate to terminate such employment at any time, with or without cause.
In addition, the Company or an Affiliate may at any time dismiss a Participant
from employment free from any liability or any claim under the Plan or any
Award, unless otherwise expressly provided in the Plan or in any Award
Agreement.

                  (f) Governing Law. The validity, construction and effect of
the Plan or any Award, and any rules and regulations relating to the Plan or any
Award, shall be determined in accordance with the laws of the State of Delaware.

                  (g) Severability. If any provision of the Plan or any Award is
or becomes or is deemed to be invalid, illegal or unenforceable in any
jurisdiction or would disqualify the Plan or any Award under any law deemed
applicable by the Committee, such provision shall be construed or deemed amended
to conform to applicable laws, or if it cannot be so construed or deemed amended
without, in the determination of the Committee, materially altering the purpose
or intent of the Plan or the Award, such provision shall be stricken as to such
jurisdiction or Award, and the remainder of the Plan or any such Award shall
remain in full force and effect.

                  (h) No Trust or Fund Created. Neither the Plan nor any Award
shall create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Affiliate and a Participant or
any other Person. To the extent that any Person acquires a right to receive
payments from the Company or any Affiliate pursuant to an Award, such right
shall be no greater than the right of any unsecured general creditor of the
Company or any Affiliate.

                  (i) No Fractional Shares. No fractional Shares shall be issued
or delivered pursuant to the Plan or any Award, and the Committee shall
determine whether cash shall be paid in lieu of any fractional Shares or whether
such fractional Shares or any rights thereto shall be canceled, terminated or
otherwise eliminated.

                  (j) Headings. Headings are given to the Sections and
subsections of the Plan solely as a convenience to facilitate reference. Such
headings shall not be deemed in any way material or relevant to the construction
or interpretation of the Plan or any provision thereof.

Section 10. Effective Date of the Plan

        The Plan shall be effective as of August 20, 2001, subject to approval
by the shareholders of the Company within one year thereafter.

Section 11. Term of the Plan

                                      -10-

<PAGE>

         No Award shall be granted under the Plan after ten years from the date
set forth in Section 10 or any earlier date of discontinuation or termination
established pursuant to Section 7(a) of the Plan. However, unless otherwise
expressly provided in the Plan or in an applicable Award Agreement, any Award
theretofore granted may extend beyond such date.
