4.2.  Purchase of Shares
      ------------------

      (a) On each Exercise Date on which he or she is employed, each Participant
will automatically and without any action on his or her part be deemed to have
exercised his or her option to purchase at the Option Price the largest number
of whole shares of Class A Common Stock which can be purchased with the amount
in the Participant's Plan Account. The balance, if any, remaining in the
Participant's Plan Account (after exercise of his or her option) as of an
Exercise Date shall be carried forward to the next Option Period, unless the
Participant has elected to withdraw from the Plan pursuant to Section 6.1
hereof.

      (b) As soon as practicable following each Exercise Date, the Company will
deliver to the Participant a certificate issued in his or her name for such
number of shares purchased by such Participant pursuant to subsection (a) above.
In the event the Company is required to obtain from any commission or agency
authority to issue any such certificate, the Company will seek to obtain such
authority. Inability of the Company to obtain from any such commission or agency
authority which counsel for the Company deems necessary for the lawful issuance
of any such certificate shall relieve the Company from liability to any
Participant except to refund to him or her the amount withheld.

4.3.  Limitations on Purchase
      -----------------------

      No Employee shall be granted an option under the Plan which permits his or
her rights to purchase Class A Common Stock under the Plan or any other employee
stock purchase plan of the Company or any of its Subsidiaries to accrue at a
rate which exceeds $25,000 (as measured by the Fair Market Value of such Class A
Common Stock at the time the option is granted) for each calendar year such
option is outstanding. For purposes of this Section 4.3, the right to purchase
Class A Common Stock under an option accrues when the option (or any portion
thereof) becomes exercisable, and the right to purchase Class A Common Stock
which has accrued under one option under the Plan may not be carried over to any
other option.

4.4.  Transferability of Rights
      -------------------------

      An option granted under the Plan shall not be transferable and is
exercisable only by the Participant. No option or interest or right therein or
part thereof shall be liable for the debts, contracts or engagements of the
Participant or his or her successors in interest or shall be subject to
disposition by alienation, anticipation, pledge, encumbrance, assignment or any
other means whether such disposition be voluntary or involuntary or by operation
of law by judgment, levy, attachment, garnishment or any other legal or
equitable proceedings (including bankruptcy), and any attempt at disposition
thereof shall be null and void and of no effect.

                                  ARTICLE V.
                  PROVISIONS RELATING TO CLASS A COMMON STOCK

5.1.  Class A Common Stock Reserved
      -----------------------------

      There shall be 500,000 authorized but unissued or reacquired shares of
Class A Common Stock reserved for issuance pursuant to this Plan, subject to
adjustment in accordance with Section 5.2 hereof.

5.2.  Adjustment for Changes in Class A Common Stock
      ----------------------------------------------

      In the event that adjustments are made in the number of outstanding shares
of Class A Common Stock or the shares are exchanged for a different class of
stock of the Company by reason of stock dividend, stock split or other
subdivision, the Committee shall make appropriate adjustments in (a) the number
and class of shares or other securities that may be reserved for purchase
hereunder and (b) the Option Price of outstanding options.

5.3.  Merger, Acquisition or Liquidation
      ----------------------------------

      In the event of the merger or consolidation of the Company into another
corporation, the acquisition by another corporation of all or substantially all
of the Company's assets or 80% or more of the Company's then outstanding voting
stock or the liquidation or dissolution of the Company, the date of exercise
with respect to outstanding options shall be the business day immediately
preceding the effective date of such merger, consolidation, acquisition,
liquidation or dissolution unless the Committee shall, in its sole discretion,
provide for the assumption or substitution of such options in a manner complying
with Section 424(a) of the Code.

5.4.  Insufficient Shares
      -------------------

      If the aggregate funds available for the purchase of Class A Common Stock
on any Exercise Date would cause an issuance of shares in excess of the number
provided for in Section 5.1 hereof, (a) the Committee shall proportionately
reduce the number of shares that would otherwise be purchased by each
Participant in order to eliminate such excess, and (b) the Plan shall
automatically terminate immediately after such Exercise Date.

5.5.  Rights as Stockholders
      ----------------------

      With respect to shares of Class A Common Stock subject to an option, a
Participant shall not be deemed to be a stockholder and shall not have any of
the rights or privileges of a stockholder. A Participant shall have the rights
and privileges of a stockholder when, but not until, a certificate for shares
has been issued to him or her following exercise of his or her option.

delivering written notice of such cessation to the Company. Upon any such
cessation, such Participant may elect either to withdraw from the Plan pursuant
to subsection (b) below or to have amounts credited to his or her Plan Account
held in the Plan for the purchase of Class A Common Stock pursuant to Section
4.2. A Participant who ceases contributions to the Plan during any Option Period
shall not be permitted to resume contributions to the Plan during such Option
Period.

      (b) A Participant may withdraw from the Plan at any time by written notice
to the Company prior to the close of business on an Exercise Date. Within 21
days after the notice of withdrawal is delivered, the Company shall refund the
entire amount, if any, in a Participant's Plan Account to him or her, and
thereupon, the Participant's payroll deduction authorization, his or her
interest in the Plan and his or her option under the Plan shall terminate. Any
Eligible Employee who withdraws from the Plan may again become a Participant in
accordance with Section 3.2 hereof.

6.2.  Termination of Eligibility
      --------------------------

      (a) If a Participant ceases to be eligible under Section 3.1 hereof for
any reason, the amount in such Participant's Plan Account will be refunded to
the Participant or his or her designated beneficiary or estate within 21 days of
his or her termination of employment or other cessation of eligibility.

      (b) Upon payment by the Company to the Participant or his or her
beneficiary or estate of the remaining balance, if any, in Participant's Plan
Account, the Participant's interest in the Plan and the Participant's option
under the Plan shall terminate.

7.1.  Condition of Employment
      -----------------------

      Neither the creation of the Plan nor an Employee's participation therein
shall be deemed to create any right of continued employment or in any way affect
the right of the Company or a Subsidiary to terminate an Employee at any time
with or without cause.

                                       6

of the Plan nor after termination of the Plan. The Plan will be submitted for
the approval of the Company's stockholders within 12 months after the date of
the Board's initial adoption of the Plan. Options may be granted prior to such
stockholder approval; provided, however, that such options shall not be
exercisable prior to the time when the Plan is approved by the stockholders;
provided further that if such approval has not been obtained by the end of said
12-month period, all options previously granted under the Plan shall thereupon
