Companys common stock, $.01 par value (the Stock) by granting Stock Purchase
Rights (each an SPR and collectively, SPRs) to such employees on July 1,
October 1, January 1 and April 1 of each year in which the Plan is in effect

Plan qualify as an employee stock purchase plan under Section 423 of the
Internal Revenue Code of 1986, as amended (the Code). The provisions of this
Plan shall be construed so as to extend
and limit participation in a manner consistent with the requirements of that
section of the Code. SECTION

would be a subsidiary corporation of the Company, as the term is defined in
Code Section 424(f) and (ii) is designated as a participant in the Plan by the
Compensation Committee of the Board of Directors of the Company (the
Compensation Committee).

2.2     Notwithstanding
the foregoing, an employee will not be granted an SPR under the Plan to the
extent the grant of such SPR would cause such employee: (i) immediately after
such SPR is granted, to own Stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Company or
any Subsidiary, (for purposes of determining stock ownership under this
Section, the rules of Code Section 424(d) shall apply); or (ii) to hold stock

include the Companys or a Subsidiarys stock option plans. For purposes hereof

defined in Section 5.4, a written payroll deduction authorization on a form
approved by the Compensation Committee (i) giving notice of the participants
election to have amounts deducted from such participants compensation from the
Company or a Subsidiary which will be used by the participant to purchase

participants compensation to be deducted by the Company or a Subsidiary from
such participants compensation during the SPR Period, which designation shall
equal no less than one percent (1%) and no more than seven and one-half percent
(7.5%) of that portion of the participants Annual Compensation actually paid
to the participant during the SPR Period;


provided, however, that in no event will the amount
deducted exceed seven and one-half percent (7.5%) of the participants Annual
Compensation (as defined below). Deductions shall commence, for each
participant, on the first payday during the SPR Period immediately following
the enrollment of such participant. The amount to be deducted each payday shall

purposes of Section 5.1, Annual Compensation means all cash compensation,
including without limitation, commissions, incentives and bonuses, overtime, or
other special payments, fees or allowances actually paid to an employee in any
one year period.

5.3     Except

forth in Section 5.1 or as otherwise may be required by law, payroll deduction
authorizations made pursuant to Section 5.1 shall not be changed.

5.4     The
enrollment period applicable to each Grant Date shall be no less than the one
month prior to such Grant Date and shall be determined by the Compensation
Committee, which shall announce such enrollment period in advance to the
eligible employees.

5.5     A
stock purchase account shall be established for each participant (the
Account), to which all payroll deductions made for that participant will be
credited. Amounts credited to Accounts will be under the control of the
Company, may be commingled with any other funds of the Company, may be
maintained or controlled as a single fund or account, and may be used for any
corporate purpose. Amounts credited to Accounts for participants who are
employees of a Subsidiary will be remitted to the Company from time to time. No
interest will be paid or credited to any participant or such participants
Account under the Plan.


5.6     In
the event that any law or regulation, in the opinion of counsel for the
Company, may prohibit the handling or use of all or any part of the funds in
the manner contemplated by the Plan, the Company may deal with such funds in
any lawful manner it may deem advisable, including (without limitation) the
deposit of any such funds in individual bank accounts opened for participants.

SECTION
6. EXERCISE OF SPRS

6.1     Except
as otherwise provided herein, on each Exercise Date shares of Stock will be
issued to each participant pursuant to SPRs granted to such participant on the
immediately preceding Grant Date in consideration for the funds credited to
such participants Account and the number of shares of Stock issued to each
participant on the Exercise Date pursuant to SPRs granted to such participant
hereunder shall equal the quotient obtained by dividing the total amount of
funds credited to such participants Account as of the close of business on the
Exercise Date by the Per Share Purchase Price (as determined in accordance with
Section 6.2). Upon each Exercise Date the funds credited to each Participants
Account used to purchase shares of Stock hereunder shall be credited to the
capital of the Company and become the property of the Company. Unless the
Companys Director of Human Resources (the DHR) is otherwise notified in
writing by a participant, any balance in each participants Account after
payment of the purchase price paid for the shares of Stock issued upon exercise
of an SPR (or, in the event the participant elects not to purchase shares
pursuant to this Section 6.1, the total amount in such Account) shall be
credited to the participants Account for the following SPR Period. Upon
receipt by the DHR of a written notice from a participant requesting the return
of any balance in a participants Account, such balance shall be promptly
refunded to the participant, without interest.


6.2     The
purchase price per share of Stock under this Plan shall be an amount equal to
85% of the reported last sale price of the Companys Stock as reported on
NASDAQ-NMS on the applicable Exercise Date (the Per Share Purchase Price).

6.3     The
Company will issue and deliver to each participant, in the participants name,
certificates representing the number of whole shares of Stock acquired on
account of the exercise of the SPR as soon as practicable following the
Exercise Date. Fractional shares will not be issued under the Plan and any
accumulated payroll deductions which would have been used to purchase
fractional shares will be applied to the participants Account for the
following SPR Period or upon written request of the participant, promptly
returned, without interest, to such participant following the applicable
Exercise Date. The participant shall be entitled to all rights as a holder of
the shares of Stock issued to such participant hereunder, including the right
to vote the shares and receive dividends thereon, as of the date such shares
are issued.

6.4     If
the Company is required to obtain any governmental authority to issue such
shares of Stock, including but not limited to, registration of the issuance of
shares of Stock under this Plan under the Securities Act of 1933, as amended
(the Securities Act), the Company will take all reasonable steps to obtain
that authority. The inability of the Company to obtain any governmental
authority considered necessary for the lawful issuance of such shares shall
relieve the Company from liability to any participant in the Plan except to
return the amount of the balance in the participants Account, without
interest.

SECTION
7. CHANGES IN ELECTION TO PURCHASE

At any time
during the SPR Period, a participant may give written notice to the DHR that
the participants payroll deductions shall cease and, in such notice, shall
designate whether the amounts in such participants Account shall be withdrawn
or left in the Account to permit such


participant to purchase shares of Stock on the
Exercise Date. Upon receipt of the notice, the participants payroll deductions
shall cease as soon as administratively practicable and the participant shall
not be eligible to resume payroll deductions during the SPR Period. If the
participant has specified in the notice required hereinabove that the amount in
such participants Account shall be withdrawn, the amount shall be paid to the
participant, without interest. In all other cases, the amount credited to the
participants account shall be applied in the manner specified in Section 6.1.

SECTION
8. CHANGE IN EMPLOYMENT STATUS

8.1     If
a participants status as an eligible employee (as defined in Section 2)
terminates for a reason other than death during the SPR Period and while the
participant has an election under Section 5 in effect, such participant shall
have the right, exercisable only by written notice to the DHR at any time after
the participants termination (but no later than the corresponding Exercise
Date), to withdraw all funds in such participants Account. If such notice is
given, all funds in the terminated participants Account shall be paid to the
participant, without interest. In all other cases, the amount credited to the participants
Account shall be applied in the manner specified in Section 6.1.

8.2     If
a participant commences an unpaid leave of absence while an election under
Section 5 is in effect with respect to the participant and such participant returns
to active service during the SPR Period, the participants payroll deductions
will be resumed if administratively practicable.
8.3     If a participant dies
  during the SPR Period when an election under Section 5 is in effect with
  respect to such participant, such participants beneficiary (as defined in
  Section 9.3) may, within 45 days after such participants death but not later
  than the corresponding Exercise Date, by written notice to the DHR elect to
  either:
(a)
  have the amount then credited to the participants
  Account applied in the manner specified in Section 6.1 and take the shares of
  Stock purchased, if any, subject to the same terms that would have applied to
  the participant had the participant survived; or(b)
  withdraw the entire amount in the participants
  Account, without interest, and terminate the participants election to
  purchase Stock.In
the event the beneficiary of such a participant shall fail to give notice
within the prescribed period, the amount then credited to the participants
Account shall be paid in cash to such beneficiary, without interest.

SECTION
9. NON-ASSIGNABILITY AND TRANSFER RESTRICTIONS;
DESIGNATION OF BENEFICIARY

9.1     No
SPR granted under the Plan shall be transferable by an employee. Except as
provided in Section 8.3, each SPR shall be exercisable only by the employee to
whom it has been granted. Any attempted voluntary assignment or transfer shall
be void. Except as provided in Section 8.3, any purported involuntary
assignment or transfer of an employees SPR granted under the Plan, whether by
operation of law or otherwise, shall have the effect of terminating such SPR,
and the amount then credited to the participants Account shall be paid in cash
to the participant or to such participants beneficiary, as the case may be,
without interest.

9.2     Shares
of Stock will not be issued pursuant to this Plan unless such issuance is
registered at the time thereof under an effective registration statement under
the Securities Act. If Stock is sold by a participant prior to the later of two
years after the Grant Date of the SPRs pursuant to which such Stock was issued
or one year after the issuance of such Stock to the participant, such sale will
disqualify the issuance of such Stock from treatment under Code Section 421(a).


9.3     A
participant may file a written designation of a beneficiary who is to receive
any Stock and/or cash. Such designation of a beneficiary may be changed by the
participant at any time by written notice to the DHR. Upon the death of a
participant and upon receipt by the Company of proof of identity and existence
at the participants death of a beneficiary validly designated by him under the
Plan, the Company shall deliver such Stock and/or cash to such beneficiary. In
the event of the death of a participant and in the absence of a beneficiary
validly designated under the Plan who is living at the time of such
participants death, the Company shall deliver such stock and/or cash to the
executor or administrator of the estate of the participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company),
the Company, in its discretion, may deliver such Stock and/or cash to the
spouse or to any one or more dependents of the participant as the Company may
designate. No beneficiary shall, prior to the death of the participant by whom
he has been designated, acquire any interest in the Stock or cash credited to
the participant under the Plan.

SECTION

10.1    The
Plan shall be administered by the Compensation Committee. The Compensation
Committee shall have the sole and absolute power and authority to construe and
interpret the Plan and adopt from time to time such rules and regulations as it
deems necessary to carry out the Plan. Determinations, interpretations or other
actions made or taken by the Compensation Committee pursuant to the provisions
of the Plan shall be final, binding and conclusive for all purposes and upon
all participants.

of Stock purchased by such participant under the Plan during the preceding
year.

11.1    The
Compensation Committee shall have the right to suspend, terminate, amend or
modify the Plan in any respect at any time without notice; provided, however,
that, except as otherwise explicitly set forth herein, no suspension,
termination, amendment or modification (collectively, a Change) may be made
more than once within a six month period, nor shall any such Change impair the
rights of an employee with respect to any outstanding SPR without the consent
of such employee, unless such Change is necessary to comply with any applicable
law. Furthermore, without the approval of the stockholders of the Company, the
Plan may not be amended in any manner that will (a) increase the number of
shares of Stock subject to the Plan, (b) cause SPRs issued under the Plan to

Code Section 423, (c) materially increase the benefits to participants under
the Plan or (d) materially modify the requirements as to eligibility for
participation in the Plan.

Plan shall terminate upon the earlier of the issuance of all of the shares of
Stock reserved for issuance under the Plan or July 1, 2009.

SECTION
12. NO RIGHT TO EMPLOYMENT

Neither
the adoption of the Plan nor the granting of an SPR under the Plan shall confer
upon any employee of the Company or any Subsidiary any right to continued
employment or participation in the Plan nor shall it interfere with the right
of the Company and any Subsidiary


to terminate the Plan or employment of any of their
employees at any time, with or without cause.

without regard to its conflicts of law principles. The provisions of the Plan

enforceability. The unenforceability of any provision of the Plan in a specific
situation shall not affect the enforceability of that provision in another
situation or the other provisions of the Plan.

disputes arising out of the interpretation or application of the Plan shall be
decided by the Compensation Committee. In the event of a dispute with a

any provision of the Plan or action by the

the Compensation Committee.
