                                 PROMISSORY NOTE

$552,312,000.00 (U.S.)            Houston, Texas                  March 31, 2001

         FOR VALUE RECEIVED, and intending to be legally bound, Continental
Express, Inc., a Delaware corporation ("Maker"), promises to pay to the order of
Continental Airlines, Inc. ("Holder") at its offices located at 1600 Smith,
HQSEO, Houston, Texas 77002, in lawful money of the United States of America and
in immediately available funds, FIVE HUNDRED FIFTY-TWO MILLION, THREE HUNDRED
TWELVE THOUSAND AND 00/100 DOLLARS ($552,312,000.00) together with interest on
the outstanding principal balance from day to day remaining at the annual rate
specified below and at the times specified below.

         The unpaid principal of this Note from time to time outstanding shall
bear interest from the date hereof through June 30, 2001 at a rate of 4.87625%
per annum. Beginning on the first day of the next calendar quarter, the interest
rate shall be automatically adjusted for such quarter to equal the sum of (i)
the three-month London Interbank Offer Rate as published at the close of the
second Business Day prior to the commencement of such quarter (or, if not
published on such day, the next preceding day on which it is published) on page
3750 of the Telerate Service ("LIBOR") plus (ii) 1.25 percent (1.25%), but in no
event to exceed the Highest Lawful Rate (as hereinafter defined). Thereafter,
the interest rate shall remain equal to LIBOR + 1.25%, but shall be
automatically adjusted for each successive calendar quarter during the term
hereof based on the immediately preceding three-month LIBOR rate as so reported,
but in no event to exceed the Highest Lawful Rate. All past due principal and,
to the fullest extent permitted by applicable law, interest shall bear interest
after the due date thereof at 18 percent (18%) per annum or, if lower, the
Highest Lawful Rate (as hereinafter defined). All interest accruing under this
Note shall be calculated on the basis of a 360-day year consisting of four
90-day quarters, unless such calculation would exceed the Highest Lawful Rate,
in which case interest will be calculated on the per annum basis of a year of
365 or 366 days, as the case may be.

         Subject to the following paragraph, the unpaid principal amount of this
Note shall be due and payable in quarterly installments of TWELVE MILLION FIVE
HUNDRED THOUSAND AND NO/100 DOLLARS ($12,500,000.00) commencing on the second
anniversary of the making of this Note, or the first Business Day thereafter,
and continuing on the first Business Day of each calendar quarter thereafter.
Interest on the unpaid principal balance of this Note shall be due and payable
on the same dates as, but in addition to, said installments of principal. On
September 30, 2005 (or, if such date is not a Business Day, the next preceding
Business Day), the entire unpaid principal balance of this Note, together with
all accrued unpaid interest, shall be due and payable in full. "Business Day"
means any day other than a Saturday or a Sunday or a day on which banking
institutions in New York, New York or Houston, Texas are authorized or required
by law or executive order to remain closed.

         At any time there remains an unpaid principal balance on this Note (or
if due to any prepayments by Maker under this paragraph or the next paragraph,
there remains only unpaid interest hereunder), if Maker's Cash and Cash
Equivalents as reflected on its balance sheet for the end of its fiscal quarter
or fiscal year exceeds $75 million (the "Threshold Amount"), then within 45 days
of the end of such fiscal quarter or fiscal year, Maker shall pay to Holder the
amount of such excess, but shall not be required to pay any accrued interest
therewith; provided, that (i) any such payment that would have the effect of
reducing Maker's Cash and Cash Equivalents as of the date of payment below the
Threshold Amount shall be reduced in the amount necessary so as not to have such
effect, (ii) any such payment shall not exceed the remaining unpaid principal
balance (or if due to any prepayments by Maker under this paragraph

                                  Page 1 of 3
<PAGE>   2

or the next paragraph, the remaining unpaid interest hereunder) at the date of
such payment, and (iii) any such payment that constitutes the final payment of
principal under this Note, shall, subject to clause (i) of this paragraph, be
accompanied by all remaining accrued and unpaid interest. In addition, if at any
time when there remains unpaid principal or interest on this Note, Maker, its
successor or any entity then controlling Maker (other than Holder) effects an
underwritten public offering of five percent (5%) or more of its then
outstanding equity securities, then, upon the closing of such offering, Maker
shall immediately pay to Holder an amount equal to the excess, if any, of (x)
the sum of (A) the net proceeds paid to Maker, its successor or such controlling
entity at such closing plus (B) Maker's Cash and Cash Equivalents on such date
over (y) the Threshold Amount; provided, that any such payment shall not exceed
the remaining unpaid principal and interest on this Note.

         Maker reserves the right to prepay this Note, in whole or in part, at
any time, without penalty or notice. All prepayments made pursuant to this
paragraph, whether designated as payments of principal or interest, shall be
applied first to accrued and unpaid interest, if any, and then to principal.

         If any payment provided herein, either of principal or interest, is not
paid when due, or in the event of the dissolution, insolvency or bankruptcy of
Maker, or if any proceedings in bankruptcy or for the relief of debtors or
readjustment of debts is filed by or against Maker, or if Holder in good faith
believes the prospect of repayment of this Note is impaired or otherwise deems
itself insecure, then in any such case Holder may, at its option and at any time
thereafter, declare this Note to be forthwith due and payable, upon which this
Note shall accelerate and be immediately due and payable in full.

         Maker, to the fullest extent permitted by applicable law, hereby
expressly and severally waives grace, and all notices, demands, presentments for
payment, notice of nonpayment, protest and notice of protest, notice of intent
to accelerate, notice of acceleration of the indebtedness due hereunder, and
diligence in collecting this Note.

         To the fullest extent permitted by applicable law, if this Note is
collected by suit or legal proceedings, including bankruptcy proceedings, Maker
agrees to pay Holder hereof the reasonable costs and reasonable attorney's fees
incurred in the collection hereof.

         No failure by Holder of this Note to exercise, and no delay in
exercising, any right or remedy hereunder shall constitute a waiver thereof on
the part of Holder; nor shall any single or partial exercise of any right or
remedy hereunder preclude any other or further exercise thereof or the exercise
of any other right or remedy.

         It is the intention of the parties hereto to conform strictly to
applicable usury laws regarding the use, forbearance or detention of the
indebtedness evidenced by this Note whether such laws are now or hereafter in
effect, including the laws of the United States of America or any other
jurisdiction whose laws are applicable, and including any subsequent revisions
to or judicial interpretations of those laws, in each case to the extent they
are applicable to this Note (the "Applicable Usury Laws"). Accordingly, if any
acceleration of the maturity of this Note or any payment by Maker or any other
person results in Maker or such other person having paid any interest in excess
of the Maximum Amount, as hereinafter defined, or if any transaction
contemplated hereby would otherwise be usurious under any Applicable Usury Laws,
then, in that event, it is agreed as follows: (i) the provisions of this
paragraph shall govern and control; (ii) the aggregate of all interest under
Applicable Usury Laws that is contracted for, charged or

                                  Page 2 of 3
<PAGE>   3

received under this Note shall under no circumstances exceed the Maximum Amount,
and any excess shall be promptly refunded to Maker by Holder hereof; (iii)
neither Maker nor any other person shall be obligated to pay the amount of such
interest to the extent that it is in excess of the Maximum Amount; and (iv) the
effective rate of interest on this Note shall be ipso facto reduced to the
Highest Lawful Rate, as hereinafter defined, and the provisions of this Note
immediately shall be deemed reformed, without the necessity of the execution of
any new document or instrument, so as to comply with all Applicable Usury Laws.
All sums paid, or agreed to be paid, to Holder hereof for the use, forbearance
or detention of the indebtedness of Maker to Holder hereof evidenced by this
Note shall, to the fullest extent permitted by the Applicable Usury Laws, be
amortized, pro rated, allocated and spread throughout the full term of the
indebtedness evidenced by this Note so that the actual rate of interest does not
exceed the Highest Lawful Rate in effect at any particular time during the full
term hereof. As used herein, the term "Maximum Amount" means the maximum
nonusurious amount of interest that may be lawfully contracted for, charged or
received by Holder hereof in connection with the indebtedness evidenced by this
Note under all Applicable Usury Laws, and the term "Highest Lawful Rate" means
the maximum rate of interest, if any, that may be charged Maker under all
Applicable Usury Laws on the principal balance of this Note from time to time
outstanding.

         THIS NOTE SHALL BE SUBJECT TO AND CONSTRUED AND ENFORCED IN ACCORDANCE
WITH THE INTERNAL LAWS OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO ANY
CONFLICTS OF LAWS PRINCIPLES.

         IN WITNESS WHEREOF, the undersigned has caused this Note to be executed
at the place and as of the date first above appearing.

<PAGE>   3

                  when his authorization for a payroll deduction becomes
                  effective and shall end on the Exercise Date of the Offering
                  Period to which such authorization is applicable unless sooner
                  terminated by the participant as provided in Section 8(a) of
                  the Plan.

4.       Offering Periods. The Plan shall be implemented by consecutive six (6)
         month Offering Periods. The Board shall have the power to change the
         duration of Offering Periods (including the commencement dates thereof)
         with respect to future Offering Periods if such change is announced at
         least five (5) days prior to the scheduled beginning of the first
         Offering Period to be affected thereafter.

5.       Payroll Deductions.

         (a)      Amount of Deduction. At the time a participant files his or
                  her subscription agreement, he or she shall elect to have
                  payroll deductions made on each pay day during the time he is
                  a participant in an Offering Period in an amount equal to any
                  whole percentage of the Compensation that he or she receives
                  on each pay day during the Offering Period. A participant may
                  elect up to 10%.

         (b)      Participant's Account. All payroll deductions made for a
                  participant shall be credited to his or her account under the
                  Plan. A participant may not make any additional payments into
                  his or her account.

         (c)      Changes in Payroll Deduction. Changes to payroll deductions
                  can be made by the participant in accordance to the below
                  restrictions. Changes are to be made by completing a new
                  subscription agreement and submitting it to the third party
                  administrator. Changes shall be made by the Company the next
                  payroll period following the receipt of such change notice
                  from the administrator or as soon as administratively
                  feasible. A participant's contribution election shall remain
                  in effect for successive Offering Periods unless changed by
                  the participant as indicated below or unless terminated as
                  provided in Section 8 hereof.

                  1)       Increase Contributions. A participant may only
                           increase the amount they are contributing during the
                           enrollment period specified which is at the start of
                           any six-month Offering Period. The change in rate
                           will become effective with the first payroll of the
                           new Offering Period.

                  2)       Decrease Contributions. A participant may decrease
                           the amount they are contributing once during any
                           six-month Offering Period. Should the participant
                           decrease their contribution to 0%, their previous
                           contributions will be used to make a purchase at the
                           end of that Offering Period. The change shall become
                           effective with the first full payroll period
                           following the date the Company receives the new
                           contribution or as soon as administratively feasible.

6.       Grant of Option. On the Enrollment Date of each Offering Period, a
         participant shall be deemed to have received an option to purchase on
         each Exercise Date during such Offering Period at the applicable
         Purchase Price a maximum number of shares of Common Stock determined by
         dividing such participant's payroll deductions accumulated prior to
         such Exercise Date and retained in the participant's account as of the
         Exercise Date by the applicable Purchase Price.

7.       Purchase of Option.

         (a)      Automatic Purchase. Unless a participant withdraws all of the
                  payroll deductions credited to his or her account prior
                  thereto as provided in Section 8 of the Plan, his or her
                  option for the purchase of Common Stock with payroll
                  deductions made during an Offering Period shall be deemed to
                  have been purchased automatically on the Exercise

                                       3
<PAGE>   4

                  Date applicable to such Offering Period for the purchase of a
                  number of shares of Common Stock that the accumulated payroll
                  deductions in his or her account at that time will purchase at
                  the applicable option price (but not in excess of the number
                  of shares for which options have been granted to the
                  participant under Section 6 of the Plan). Whole and fractional
                  shares shall be purchased. During a participant's lifetime, a
                  participant's option to purchase shares hereunder is
                  exercisable only by him or her.

         (b)      Sale of Stock. Participants may sell their stock, transfer
                  shares to a broker, or take stock certificates of shares after
                  completing a 6-month holding period. The 6-month holding
                  period begins from the date the stock is purchased at the end
                  of the Offering Period. To initiate this process, the
                  participant must contact the third party administrator for
                  instructions.

8.       Withdrawal.

         (a)      General. A participant may withdraw from the plan and receive
                  all of the payroll deductions credited to his or her account
                  and not yet used to exercise his or her option under the Plan
                  at any time during an Offering Period up to 15 days prior to
                  the close of the Offering Period by submitting the proper
                  paperwork to the third party administrator. All of the
                  participant's payroll deductions contributed during that
                  Offering Period shall be paid to such participant, such
                  participant's option for the Offering Period shall be
                  automatically terminated, and no further payroll deductions
                  for the purchase of shares shall be made for such Offering
                  Period.

         (b)      Effect on Subsequent Participation. A participant's withdrawal
                  from the Plan and the receipt of the payroll deductions
                  credited to his or her account shall not have any effect upon
                  his or her eligibility to participate in any similar plan that
                  may hereafter be adopted by the Company or in succeeding
                  Offering Periods that commence after the termination of the
                  Offering Period from which the participant withdraws. If,
                  however, a participant withdraws from the Plan during an
                  Offering Period, payroll deductions shall not resume at the
                  beginning of the succeeding Offering Period unless the
                  participant delivers to the third party administrator a new
                  subscription agreement prior to the commencement of such
                  succeeding Offering Period.

         (c)      Termination of Employment. Upon a participant's ceasing to be
                  an Employee, for any reason, he or she shall be deemed to have
                  elected to withdraw from the Plan and the payroll deductions
                  credited to such participant's account during the Offering
                  Period but not yet used to exercise the option shall be
                  returned to such participant or, in the case of his or her
                  death, to the person or persons entitled thereto under Section
                  12 of the Plan, and such participant's option shall be
                  automatically terminated. Notwithstanding the preceding
                  sentence, a participant who receives payment in lieu of notice
                  of employment shall be treated as continuing to be an Employee
                  for the participant's customary number of hours per week of
                  employment during the period in which the participant is
                  subject to such payment in lieu of notice.

         9.       Interest. No interest shall accrue on the payroll deductions
                  of a participant in the Plan.

10.      Stock.

         (a)      Maximum Shares of Kforce Common Stock. The maximum number of
                  shares of the Company's Common Stock that shall be made
                  available for sale under the Plan shall be six million
                  (6,000,000) shares, subject to adjustment upon changes in
                  capitalization of the Company as provided in Section 16 of the
                  Plan. If, on a given Exercise Date, the number of shares with
                  respect to which options are to be exercised exceeds the
                  number of shares available under the Plan, the Company shall
                  make a pro rata allocation of the shares remaining available
                  for purchase in as uniform a manner as shall be practicable
                  and as it

                                       4
<PAGE>   5

                  shall determine to be equitable, and the balance of payroll
                  deductions credited to the account of each participant shall
                  be returned to him or her as promptly as possible.

         (b)      Participant's Interest in Option Stock. The participant shall
                  have no interest or voting right in shares covered by his or
                  her option until such option has been exercised.

         (c)      Registration of Stock. Shares of Kforce Common Stock to be
                  delivered to a participant under the Plan shall be registered
                  in the name of the participant or in the name of the
                  participant and his or her spouse as joint tenants with right
                  of survivorship.

11.      Administration. The Plan shall be administered by the Board or a
         committee of members of the Board appointed by the Board. The Board or
         its committee shall have full and exclusive discretionary authority to
         construe, interpret and apply the terms of the Plan, to determine
         eligibility and to adjudicate all disputed claims filed under the Plan.
         Every finding, decision and determination made by the Board or its
         committee shall, to the full extent permitted by law, be final and
         binding upon all parties.

12.      Designation of Beneficiary. A participant may file a written
         designation of a beneficiary who is to receive any shares and cash, if
         any, from the participant's account under the Plan in the event of such
         participant's death subsequent to an Exercise Date on which the option
         is exercised but prior to delivery to such participant of such shares
         and cash. In addition, a participant may file a written designation of
         a beneficiary who is to receive any cash from the participant's account
         under the Plan in the event of such participant's death prior to
         exercise of the option. If a participant is married and the designated
         beneficiary is not the spouse, spousal consent shall be required for
         such designation to be effective. Such designation of beneficiary may
         be changed by the participant at any time by written notice. In the
         event of the death of the 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 shares
         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 shares and/or cash to the spouse or to any one or more
         dependents or relatives of such participant, or, if no spouse,
         dependent or relative is known to the Company, then to such other
         person as the Company may designate.

13.      Transferability. Neither payroll deductions credited to a participant's
         account nor any rights with regard to the exercise of an option or to
         receive shares under the Plan may be assigned, transferred, pledged or
         otherwise disposed of in any way (other than by will, the laws of
         descent and distribution) by the participant. Any such attempt at
         assignment, transfer, pledge or other disposition shall be without
         effect, except that the Company may treat such act as an election to
         withdraw funds from an Offering Period in accordance with Section 8 of
         the Plan.

14.      Use of Funds. All payroll deductions received or held by the Company
         under the Plan may be used by the Company for any corporate purpose,
         and the Company shall not be obligated to segregate such payroll
         deductions.

15.      Reports. Individual accounts shall be maintained for each participant
         in the Plan. Statements of account shall be given to participating
         Employees at least annually, which statements shall set forth the
         amounts of payroll deductions, the Purchase Price, the number of shares
         purchased and the remaining cash balance, if any.

16.      Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
         Merger or Asset Sale.

         (a)      Changes in Capitalization. Subject to any required action by
                  the shareholders of the Company, (i) the Reserves, (ii) the
                  maximum number of shares each participant may purchase during
                  each Offering Period, (iii) the Purchase Price per share, and
                  (iv) the

                                       5
<PAGE>   6

                  number of shares of Common Stock covered by each option under
                  the Plan that has not yet been exercised shall be
                  proportionately adjusted for any increase or decrease in the
                  number of issued shares of Common Stock resulting from a stock
                  split, reverse stock split, stock dividend, combination or
                  reclassification of the Common Stock, or any other increase or
                  decrease in the number of shares of Common Stock effected
                  without receipt of consideration by the Company; provided,
                  however, that conversion of any convertible securities of the
                  Company shall not be deemed to have been "effected without
                  receipt of consideration." Such adjustment shall be made by
                  the Board, whose determination in that respect shall be final,
                  binding and conclusive. Except as expressly provided herein,
                  no issuance by the Company of shares of stock of any class, or
                  securities convertible into shares of stock of any class,
                  shall affect, and no adjustment by reason thereof shall be
                  made with respect to, the number or price of shares of Common
                  Stock subject to an option.

         (b)      Dissolution or Liquidation. In the event of the proposed
                  dissolution or liquidation of the Company, the Offering Period
                  then in progress shall be shortened by setting a new Exercise
                  Date (the "New Exercise Date"), and shall terminate
                  immediately prior to the consummation of such proposed
                  dissolution or liquidation, unless provided otherwise by the
                  Board. The New Exercise Date shall be before the date of the
                  Company's proposed dissolution or liquidation. The Board shall
                  notify each participant in writing, at least ten (10) business
                  days prior to the New Exercise Date, that the Exercise Date
                  for the participant's option has been changed to the New
                  Exercise Date and that the participant's option shall be
                  exercised automatically on the New Exercise Date, unless prior
                  to such date the participant has withdrawn the payroll
                  deductions credited to his or her account as provided in
                  Section 8 of the Plan.

         (c)      Merger or Asset Sale. In the event of a proposed sale of all
                  or substantially all of the assets of the Company, or the
                  merger of the Company with or into another corporation, the
                  Company shall use its best efforts to have each outstanding
                  option assumed or an equivalent option substituted by the
                  successor corporation or a parent or Subsidiary of the
                  successor corporation. In the event that the successor
                  corporation refuses to assume or substitute for the option,
                  the Company shall set a New Exercise Date and any Offering
                  Periods then in progress shall end on the New Exercise Date.
                  The New Exercise Date shall be the date immediately prior to
                  the date of the Company's proposed sale or merger. The Board
                  shall notify each participant in writing, at least ten (10)
                  business days prior to the New Exercise Date, that the
                  Exercise Date for the participant's option has been changed to
                  the New Exercise Date and that the participant's option shall
                  be exercised automatically on the New Exercise Date, unless
                  prior to such date the participant has withdrawn the payroll
                  deductions credited to his or her account as provided in
                  Section 8 of the Plan.

17.      Amendment or Termination. The Board of Directors of the Company may at
         any time and for any reason terminate or amend the Plan. Except as
         provided in Section 16 of the Plan, no such termination can affect
         options previously granted; provided, that an Offering Period may be
         shortened by the Board of Directors to an earlier Exercise Date and the
         Plan may be terminated immediately thereafter if the Board determines
         that the termination of the Plan is in the best interests of the
         Company and its shareholders. Except as provided in Section 16 of the
         Plan, no amendment may make any change in any option theretofore
         granted that adversely affects the rights of any participant. To the
         extent necessary to comply with Section 423 of the Code (or any
         successor rule or provision or any other applicable law, regulation or
         stock exchange rule), the Company shall obtain shareholder approval for
         any amendment to the Plan in such a manner and to such a degree as
         required. Without shareholder consent and without regard to whether any
         participant rights may be considered to have been "adversely affected,"
         the Board (or its committee) shall be entitled to change Offering
         Periods, limit the frequency and/or number of changes in the amount
         withheld during an Offering Period, establish the exchange ratio
         applicable to amounts designated by a participant in order to adjust
         for delays or mistakes in the Company's

                                       6
<PAGE>   7

         processing of properly completed withholding elections, establish
         reasonable waiting and adjustment periods and/or accounting and
         crediting procedures to ensure that amounts applied toward purchase of
         Common Stock for each participant properly correspond with amounts
         withheld from the participant's Compensation, and establish such other
         limitations or procedures as the Board (or its committee) determines in
         its sole discretion advisable that are consistent with the Plan.

18.      Notices. All notices or other communications by a participant to the
         Company under or in connection with the Plan shall be deemed to have
         been duly given when received in the form specified by the Company at
         the location, or by the person, designated by the Company for the
         receipt thereof.

19.      Conditions Upon Issuance of Shares of Kforce Common Stock. Shares of
         Kforce Common Stock shall not be issued with respect to an option
         unless the exercise of such option and the issuance and delivery of
         such shares pursuant thereto shall comply with all applicable
         provisions of law, domestic or foreign, including, without limitation,
         the Securities Act of 1933, as amended, the Securities Exchange Act of
         1934, as amended (the "Exchange Act"), the rules and regulations
         promulgated thereunder, and the requirements of any stock exchange upon
         which the shares may be listed, and shall be further subject to the
         approval of counsel for the Company with respect to such compliance. As
         a condition to the exercise of an option, the Company may require the
         person exercising such option to represent and warrant at the time of
         any such exercise that the shares are being purchased only for
         investment and without any present intention to sell or distribute such
         shares if, in the opinion of counsel for the Company, such a
         representation is required by any of the aforementioned applicable
         provisions of law. The terms and conditions of options granted under
         the Plan to, and the purchase of shares by, persons subject to Section
         16 of the Exchange Act shall comply with the applicable provisions of
         Rule 16b-3 under the Exchange Act. This Plan shall be deemed to
         contain, and such options shall contain, and the shares issued upon
         exercise thereof shall be subject to, such additional conditions and
         restrictions as may be required by Rule 16b-3 under the Exchange Act to
         qualify for the maximum exemption from Section 16 of the Exchange Act
         with respect to Plan transactions.

         In addition to the restriction described in the first paragraph of this
         Section 19, the shares of the Company's Common Stock received by any
         person upon the exercise of an option may not be sold, assigned,
         transferred, pledged or otherwise disposed of for a period of six
         months from the date of such exercise. The shares of Company's Common
         Stock received upon the exercise of an option may bear a legend to such
         effect or the Company may require the person receiving such shares to
         execute an agreement to such effect.

20.      Tax Withholding. At the time the option is exercised, in whole or in
         part, or at the time some or all of the Company's Common Stock issued
         under the Plan is disposed of, the participant must make adequate
         provision for the Company's federal, state or other tax withholding
         obligations, if any, that arise upon the exercise of the option or the
         disposition of the Common Stock. At any time, the Company may, but
         shall not be obligated to, withhold from the participant's compensation
         the amount necessary for the Company to meet applicable withholding
         obligations, including any withholding required to make available to
         the Company any tax deductions attributable to sale or early
         disposition of Common Stock by the Employee.

21.      Term of Plan. The Plan shall become effective upon the earlier to occur
         of its adoption by the Board of Directors or its approval by the
         shareholders of the Company. It shall continue in effect for a term of
         ten (10) years unless terminated under Section 17 of the Plan.
