<PAGE>   3

Eligible Employee who elects to participate in the Q.S.P. Plan for an Offering
Period shall elect on such Authorization Card a whole percentage of Base Pay
(such percentage not to exceed 10% of Base Pay) to be withheld by payroll
deduction, which, upon the exercise of the Option granted to such Eligible
Employee with respect to such Offering Period, shall be contributed to the
Company as payment for shares of Stock purchased pursuant to the Option.

           (b) The Authorization Card must be submitted to the Administrator
during the two-week period commencing one month prior to the first day of the
Offering Period and ending two weeks prior to the first day of the Offering
Period in order to participate in the Q.S.P. Plan during such Offering Period.

           (c) Except as otherwise provided in subsection (b) and Section 11, an
Employee's Authorization Card shall operate with respect to each Offering Period
commencing after delivery of the Authorization Card to the Administrator for
which such Employee is an Eligible Employee.

        7. PAYROLL DEDUCTIONS.

           (a) Cash compensation payable to an Eligible Employee who elects to
participate in the Q.S.P. Plan for an Offering Period shall be reduced each
Payday through payroll deductions by an amount equal to the whole percentage of
Base Pay payable on such Payday elected by the Eligible Employee under Section
6.

           (b) The amount of each Eligible Employee's payroll deduction shall be
held by the Company and credited to an account established for such Eligible
Employee. Neither the Company nor any Subsidiary Corporation shall pay any
interest on the funds credited to an Eligible Employee's account under the
Q.S.P. Plan.

           (c) An Eligible Employee participating in the Q.S.P. Plan may change
his or her payroll deduction percentage for any Offering Period by submitting a
new Authorization Card to the Administrator during the Enrollment Period for
such Offering Period. Such change in payroll deduction percentage shall become
effective on the first day of the Offering Period.

           (d) During a leave of absence from the Company or a Subsidiary
Corporation which is approved by the Company or Subsidiary Corporation, as
applicable, and which meets the requirements of Treasury Regulation Section
1.421-7(h)(2), an Eligible Employee may continue to participate in the Q.S.P.
Plan by making cash payments to the Company on each Payday equal to the dollar
amount of the payroll deduction made for such Eligible Employee for the Payday
next preceding the first day of such Eligible Employee's leave of absence.

        8. GRANT OF OPTIONS; EXERCISE OF OPTIONS.

           (a) Each Eligible Employee participating in the Q.S.P. Plan shall be
granted an option on the first day of the Offering Period for each Offering
Period for which such Eligible Employee elects to participate. The term of each
Option shall end on the last day of the Offering Period for which the Option is
granted, and such Option shall expire immediately thereafter. The number of
shares of Stock subject to each Option shall be the quotient of the total
payroll deductions made for the Eligible Employee during the Offering Period,
divided by the Option Price, excluding fractional shares of Stock; provided,
however, that the number of shares of Stock subject to each Option shall not
exceed 5,000 shares.

           (b) Except as otherwise provided in subsection (c), each Eligible
Employee participating in the Q.S.P. Plan shall be deemed to have exercised his
or her Option on the last day of the Offering Period, to the extent that the
balance of payroll deductions credited to such Eligible Employee's account under
the Q.S.P. Plan is sufficient to purchase, at the Option Price, whole shares of
Stock. No fractional shares of Stock shall be purchased upon the exercise of the
Option and any funds credited to such Eligible Employee's account, remaining
after the purchase of whole shares of Stock upon exercise of an option, shall
remain credited to such Eligible Employee's account and carried forward for
purchase of shares of Stock pursuant to the Option, if any, granted to such
Eligible Employee for the next following offering Period.



                                       3

<PAGE>   4

           (c) An Eligible Employee's Option shall not be exercised on the last
day of the offering Period if such Eligible Employee instructs the Administrator
in writing at least two weeks prior to the last day of the Offering Period that
such Option is not to be exercised. As soon as practicable after receipt of such
instruction, the Administrator shall pay to such Eligible Employee in cash in
one lump sum the balance of payroll deductions credited to such Eligible
Employee's account under the Q.S.P. Plan, without the payment of any interest
thereon.

           (d) If the total number of shares of Stock for which options are to
be exercised on any date exceeds the number of shares remaining unsold under the
Q.S.P. Plan (after deduction of all shares for which Options have theretofore
been exercised), the Administrator shall make a pro rata allocation of the
available remaining shares in as nearly a uniform manner as shall be practicable
and any balance of payroll deductions credited to the accounts of Eligible
Employees which have not been applied to the purchase of shares of Stock shall
be paid to such Eligible Employees in cash in one lump sum as soon as
practicable, without payment of any interest thereon.

           (e) Notwithstanding any provision in this Section to the contrary, an
Eligible Employee shall not be granted an Option:

               (i) if, immediately after the Option is granted, such Employee
    would own stock possessing 5% or more of the total combined voting power or
    value of all classes of stock of the Company, any Parent Corporation or any
    Subsidiary Corporation. For purposes of determining stock ownership under
    this paragraph, the rules of Code Section 425(d) shall apply and stock which
    an Eligible Employee may purchase under outstanding options held by such
    Eligible Employee shall be treated as stock owned by such Eligible Employee;
    or

               (ii) which permits such Eligible Employee's rights to purchase
    stock under all employee stock purchase plans of the Company, any Parent
    Corporation or any Subsidiary Corporation, which qualify under Code Section
    423, to accrue at a rate which exceeds $25,000 of the fair market value of
    such stock (determined at the time such option is granted) for each calendar
    year in which such option is outstanding at any time. For purpose of the
    limitations imposed by this paragraph, the right to purchase stock under an
    option accrues when the option (or any portion thereof) first becomes
    exercisable during the calendar year, the right to purchase stock under an
    option accrues at the rate provided in the option (but in no case may such
    rate exceed $25,000 of fair market value of such stock determined at the
    time such option is granted for any one calendar year), and a right to
    purchase stock which has accrued under the option may not be carried over to
    any other option.

        9. OPTION PRICE.

           (a) The per share exercise price of each option (the "Option Price")
shall be an amount equal to the lesser of:

               (i) 85% of the fair market value of a share of Stock on the date
    the Option is granted (the first day of the Offering Period); or

               (ii) 85% of the fair market value of a share of the Stock on the
    date such option is exercised (the last day of the Offering Period).

           (b) For purposes of subsection (a), the fair market value of a share
of Stock as of a given date shall be:

               (i) the closing price of a share of Stock on the principal
    exchange on which shares of Stock are then trading, if any, on such date,
    or, if shares were not traded on such date, then on the next preceding
    trading day during which a sale occurred;

               (ii) if such Stock is not traded on an exchange but is quoted on
    NASDAQ or a successor quotation system, the last sales price (if the Stock
    is then listed as a National Market issue under the NASD National Market
    System) or the mean between the closing representative bid and asked prices
    (in all other cases) for the Stock of such date as reported by NASDAQ or a
    successor quotation system;



                                       4
<PAGE>   5

               (iii) if such Stock is not publicly traded on an exchange and not
    quoted on NASDAQ or a successor quotation system, the mean between the
    closing bid and asked prices for the Stock on such date as determined in
    good faith by the Committee; or

               (iv) if the Stock is not publicly traded, the fair market value
    established by the Administrator acting in good faith.

        10. ISSUANCE OF CERTIFICATES.

           (a) The Administrator shall, as soon as practicable after the
exercise of any Option, deliver to the Eligible Employee exercising the Option a
certificate evidencing the whole shares of Stock purchased by such Eligible
Employee under the Q.S.P. Plan from funds credited to such Eligible Employee's
account.

           (b) In the event the Administrator is required to obtain authority to
issue certificates for any shares of Stock purchased by an Eligible Employee
under the Q.S.P. Plan from any commissioner or agency, the Administrator will
seek to obtain such authority. If the Administrator in unable, after reasonable
efforts, to obtain such authority, the Administrator, the Company and any
Subsidiary Corporations shall be relieved from all liability, and each such
Eligible Employee shall be paid the balance of payroll deductions credited to
such Eligible Employee's account under the Q.S.P. Plan in cash in one lump sum
as soon as practicable, without the payment of any interest thereon.

        11. CESSATION OF PARTICIPATION.

           (a) Except as otherwise provided in Subsection 7(d), an Eligible
Employee shall cease to participate in the Q.S.P. Plan in the event that:

               (i) the Administrator receives written instructions from the
    Eligible Employee to terminate such Eligible Employee's participation in the
    Q.S.P. Plan;

               (ii) the Eligible Employee resigns or is discharged from
    employment by the Company or a Subsidiary Corporation, or has a leave of
    absence from the Company or a Subsidiary Corporation which is not approved
    by the Company or a Subsidiary Corporation or which does not meet the
    requirements of Treasury Regulation Section 1.421-7(h)(2); or

               (iii) the Employee dies.

           (b) Upon cessation of participation by an Eligible Employee, such
Eligible Employee's payroll deductions shall cease. If such cessation of
participation occurs during the last two weeks of an Offering Period, such
Eligible Employee's Option shall be exercised on the last day of the Offering
Period in accordance with Section 8(b). Upon cessation of participation at any
other time, any balance of payroll deductions credited to such Eligible
Employee's account under the Q.S.P. Plan shall be paid to the Employee in cash
in one lump sum as soon as practicable after cessation of participation, without
payment of any interest thereon.

           (c) An Eligible Employee shall not be eligible to participate in the
Q.S.P. Plan during the Offering Period which immediately follows the Offering
Period during which such Employee voluntarily terminated participation in the
Q.S.P. Plan under paragraph (a)(i).

         12. TRANSFER OF OPTION. Options granted pursuant to the Q.S.P. Plan
shall not be transferable by an Eligible Employee, other than by will or the
laws of descent and distribution, and shall be exercisable during the Eligible
Employee's lifetime only by such Eligible Employee.

         13. BENEFICIARY.

           (a) Each Eligible Employee shall designate on his or her
Authorization Card a beneficiary or beneficiaries and may, without such
beneficiaries consent, change such designation. Any designation shall be
effective 



                                       5
<PAGE>   6

only after it is received by the Administrator and shall be controlling over any
disposition by will or otherwise. Upon the death of an Eligible Employee, the
balance of payroll deductions credited to such Eligible Employee's account shall
be paid or distributed to the designated beneficiary or beneficiaries or, in the
absence of such designation, to the executor or administrator of the Eligible
Employee's estate, and, in either event, neither the Administrator, the Company
nor any Subsidiary Corporation shall be under any further liability to anyone.

        14. RECAPITALIZATION. If there shall be any change in the Stock subject
to the Q.S.P. Plan or the Stock subject to any Option, through merger,
consolidation, reorganization, recapitalization, reincorporation, stock split,
stock dividend (in excess of 2% of the fair market value of the Stock) or other
change in the corporate structure of the Company, appropriate adjustments shall
be made by the Administrator to the aggregate number of shares subject to the
Q.S.P. Plan and the number of shares and the price per share subject to
outstanding Options in order to preserve, but not to increase, the benefits of
the Eligible Employees hereunder; provided, however, that subject to any
required action by the shareholders, if the Company shall not be the surviving
corporation in any such merger, consolidation or reorganization, every Option
outstanding shall terminate, unless the surviving corporation shall (subject to
applicable provisions of the Code) issue a new option therefor or assume (with
appropriate changes) the existing Option. If the Option shall terminate by
reason of such merger, consolidation, or reorganization, then any provision
herein to the contrary notwithstanding, any option held by an Eligible Employee
may be exercised, in whole or in part, by such Eligible Employee at any time
prior to or concurrently with consummation of such merger, consolidation or
reorganization.

        15. RIGHTS AS A SHAREHOLDER. An Eligible Employee shall have no rights
as a shareholder of the Company with respect to any shares of Stock covered by
Options until the date of the issuance of a certificate for such shares of
Stock. No adjustments shall be made for dividends (ordinary or extraordinary,
whether in cash, securities or other property) or distributions or other rights
for which the record date is prior to the date such certificate is issued,
except as otherwise expressly provided herein.

        16. COSTS; INDEMNIFICATIONS.

           (a) All costs and expenses incurred in administering the Q.S.P. Plan
shall be paid by the Company.

           (b) In addition to such other rights of indemnification as the
Administrator may have as a director or officer of the Company, the Company
shall indemnify and hold the Administrator harmless against any and all
liability, loss, costs, damages, attorneys' fees and other expenses the
Administrator may sustain or incur in connection with administration of the
Q.S.P. Plan, except for liability, loss, costs, damages, attorneys' fees and
other expenses caused by the negligence of the Administrator or his agent;
provided, that within 60 days after the institution of any action, suit or
proceeding the Administrator shall in writing offer the Company the opportunity
to handle, prosecute or defend the same, at the Company's own expense. The
Administrator shall have the right, but not the obligation, to adjust, settle,
or compromise any claim, obligation, debt, demand, suit or judgment against the
Administrator, and if such settlement is approved by independent legal counsel
selected by the Company then the Company shall reimburse the Administrator for
all sums of money the Administrator may pay or become liable to pay against
which the Administrator is indemnified hereunder.

        17. AMENDMENT OR TERMINATION OF THE Q.S.P. PLAN. The Board of Directors
may at any time, with respect to any shares of Stock not then subject to Options
suspend or terminate the Q.S.P. Plan, and may amend the Q.S.P. Plan from time to
time as the Board of Directors may deem advisable; provided, however, that
except as provided in Section 14 hereof, the Board of Directors shall not amend
the Q.S.P. Plan in the following respects without the affirmative vote of
approval by a majority of the outstanding shares of Stock of the Company:

           (a) To increase the maximum number of shares of Stock subject to the
Q.S.P. Plan;

           (b) To change the designation or class of employees eligible to
receive Options under the Q.S.P. Plan; or

           (c) In any manner which would cause the Q.S.P. Plan to no longer be
an employee stock purchase plan under Code Section 423.



                                       6
<PAGE>   7

        18. APPLICATION OF FUNDS. The proceeds received by the Company from the
sale of Stock pursuant to the exercise of Options shall be deposited in the
account of the general corporate funds of the Company.

        19. APPROVAL OF SHAREHOLDERS. The Q.S.P. Plan shall become effective on
the date of the affirmative vote by a majority of the outstanding shares of
Stock of the Company approving the Q.S.P. Plan (which approval must occur within
12 months before or after the date the Q.S.P. Plan is adopted by the Board of
Directors).

        20. NO RIGHTS AS AN EMPLOYEE. Nothing in the Q.S.P. Plan shall be
construed to give any person the right to remain in the employ of the Company or
to affect the right of the Company to terminate the employment of any person at
any time with or without cause.

        21. TITLES. Titles are provided herein for convenience only and are not
to serve as a basis for interpretation or construction of the Q.S.P. Plan.

        22. CONFORMITY TO SECURITIES LAWS. The Plan is intended to conform to
the extent necessary with all provisions of the Securities Act of 1933, as
amended, and the Securities Exchange Act of 1934, as amended, and any and all
regulations and rules promulgated by the Securities and Exchange Commission
thereunder, including without limitation Rule 16b-3. Notwithstanding anything
herein to the contrary, the Plan shall be administered, and Options shall be
granted and may be exercised, only in such a manner as to conform to such laws,
rules and regulations. To the extent permitted by applicable law, the Q.S.P.
Plan and Options granted hereunder shall be deemed amended to the extent
necessary to conform to such laws, rules and regulations.
