2000 (i.e., 2.0833% of the Membership Interests covered by this Option shall
vest each month, with 2.0833% vesting on January 1, 2000 and 2.0833% vesting
   2

         The Option may be exercised from time to time after the Effective Date,
but no later than the Expiration Date, as to any Membership Interests covered by
this Option which have vested in accordance with the terms of this Option. In
each case the number of Membership Interests which may be purchased shall be
calculated to the nearest full Membership Interest.

fully vested and exercisable prior to the scheduled dates above if (i)

in cash or by certified, bank cashier's or teller's check or by Membership

been approved by the Company, including any approved cashless exercise
mechanism. In the event all or part of the Exercise Price is paid in Membership
Interests, any excess of the value of such Membership Interests over the

in kind, and may be represented by one or more Membership Interest certificates;

state or Federal income tax as a result of the exercise of an Option, as a
condition to the exercise thereof, Optionee may be required to make arrangements
satisfactory to the Company to enable it to satisfy such withholding
requirements. Payments of such withholding requirements may be made, in the
discretion of the Company, (i) in cash, (ii) by delivery of Membership Interests
registered in the name of Optionee as have a value (determined by multiplying
the Fair Market Value at the time of exercising by the Percentage Interest of
such Membership Interests) equal to the amount to be withheld, (iii) by the
Company not issuing such number of Membership Interests subject to the Option

                                       2

exercising by the Percentage Interest of such Membership Interests) equal to the
amount to be withheld, (iv) withholding from other compensation due to Optionee,
or (v) any combination of (i), (ii), (iii) and (iv) above.

following applicable conditions:

                  (a) The admission of such Membership Interests to listing on
all stock exchanges or markets on which the Membership Interests are then listed
to the extent such admission is necessary;

                  (b) The completion of any registration or other qualification
of such Membership Interests under any federal or state securities laws or under
the rulings or regulations of the Securities and Exchange Commission or any
other governmental regulatory body, which the Company shall in its sole
discretion deem necessary or advisable, or the determination by the Company in
its sole discretion that no such registration or qualification is required;

                  (c) The obtaining of any approval or other clearance from any
federal or state governmental agency which the Company shall, in its sole
discretion, determine to be necessary or advisable; and

                  (d) The lapse of such reasonable period of time following the
exercise of the Option as the Company from time to time may establish for
reasons of administrative convenience.

Notwithstanding the foregoing, the Company shall not be obligated to issue or
deliver any certificates for Membership Interests purchased upon the exercise of
this Option or any portion thereof, unless required by Federal, or state law.

         7. COMPLIANCE WITH SECURITIES AND OTHER LAWS. In no event shall the
Company be required to sell, issue or deliver Membership Interests pursuant to
this Option if in the opinion of the Company the issuance thereof would
constitute a violation by either Optionee or the Company of any provision of any
law or regulation of any governmental authority or any securities exchange. As a
condition of any sale or issuance of Membership Interests pursuant to this
Option, the Company may place legends on the certificates representing the
Membership Interests, issue stop-transfer orders and require such agreements or

                                       4
   5
undertakings from Optionee as the Company may deem necessary or advisable to
assure compliance with any such law or regulation, including, if the Company or
its counsel deems it appropriate, representations from Optionee that Optionee is
acquiring the Membership Interests solely for investment and not with a view to
distribution and that no distribution of the Membership Interests acquired by
Optionee will be made unless registered pursuant to applicable federal and state
securities laws or unless, in the opinion of counsel to the Company, such
registration is unnecessary.

         8. TRANSFERABILITY. This Option is non-transferable by Optionee, either
voluntarily or by operation of law, other than by will or the laws of descent
and distribution or pursuant to a qualified domestic relations order as defined
in the Code, and shall be exercisable during Optionee's lifetime only by
Optionee, Optionee's executor; or by the spouse of Optionee who obtained the
Option pursuant to such qualified domestic relations order described herein.
Notwithstanding the foregoing, this Option may be assigned, in connection with
Optionee's estate plan, in whole or in part, during Optionee's lifetime to one
or more members of Optionee's immediate family or to a trust established
exclusively for one or more of such immediate family members. Rights under the
assigned portion may be exercised by the person or persons who acquire a
proprietary interest in such Option pursuant to the assignment. The terms
applicable to the assigned portion shall be the same as those in effect for the
Option immediately before such assignment and shall be set forth in such
documents issued to the assignee as the Company deems appropriate. For purposes
of this Section 8, the term "immediate family" means an individual's spouse,
children, stepchildren, grandchildren and parents. Any attempt to so transfer,

right or privileges granted hereby contrary to the provisions hereof shall be
null and void ab initio and of no force or effect.

         9. OCCURRENCE OF INITIAL PUBLIC OFFERING. From and after the occurrence
of an Initial Public Offering, each Membership Interest held as a result of an
exercise of this Option will automatically be exchanged into that number of
shares of the common stock of the Public Company determined by multiplying the
Percentage Interest of such Membership Interests by the Fair Market Value, and
dividing by the Share Value. Any shares of the common stock of the Public
Company received by Optionee in exchange for Membership Interests shall be
subject to purchase by Allen or the Company in the same manner as Membership
Interests upon the termination of the employment relationship of the Optionee
for Cause as described in Sections 4(b) and 4(c). It is the intent of this
Section 9 that Optionee will receive that number of shares of common stock of
the Public Company necessary to provide Optionee with an aggregate economic
benefit equal to the value of Optionee's Options and Membership Interests.

         10. ADJUSTMENTS.

                  (a) Subject to any required action by the Board and/or the
Members, the number of Membership Interests covered by this Option and the
Exercise Price thereof shall be proportionately adjusted for any increase or
decrease in the number of issued Membership Interests resulting from a
subdivision or consolidation of Membership Interests or the distribution of

                                       5
   6
Membership Interests on Membership Interests without consideration.
Notwithstanding the foregoing, nothing herein shall be interpreted to provide
dilution protection with respect to this Option in the event, and to the extent
of, any additional equity contribution to the Company or the issuance of
Membership Interests for consideration.

                  (b) Subject to the provisions of Section 10(d), and subject to
any required action by the Board, and/or the Members, if the Company shall merge
with another entity and the Company is the surviving entity in such merger and
under the terms of such merger the Membership Interests outstanding immediately
prior to the merger remain outstanding and unchanged, this Option shall continue
to apply to the Membership Interests subject thereto and shall also pertain and
apply to any additional securities and other property, if any, to which a holder
of the number of Membership Interests subject to this Option would have been
entitled as a result of the merger.

                  (c) If the Company shall merge with another entity and the
Company is not the surviving entity in such merger, and such merger does not
constitute a Change in Control, the Company, may, in its discretion, do one or
more of the following: (i) shorten the period during which the Option is
exercisable (provided it remains exercisable for at least 30 days after the date
of notice such shortening is given to Optionee); (ii) accelerate any vesting
schedule to which this Option is subject; (iii) arrange to have the surviving or
successor entity assume the Option or grant a replacement option with
appropriate adjustments in the option price and adjustments in the number and
kind of securities issuable upon exercise or adjustments so that the Option or
its replacements represent the right to purchase the shares of stock, securities
or other property (including cash) as may be issuable or payable as a result of
such merger with respect to or in exchange for the number of Membership
Interests purchasable and receivable upon the exercise of this Option had such
exercise occurred in full prior to such merger, or (iv) with the prior written
consent of Optionee, cancel this Option upon the payment to Optionee in cash,
with respect to this Option to the extent then exercisable (including any Option
as to which the exercise has been accelerated as contemplated in clause (ii)
above), of any amount that is the equivalent of the Option Spread at the
effective time of the merger.

                  (d) Notwithstanding any other provision contained in this
Agreement, in the event of a Change of Control, any unvested portion of this
Option shall immediately vest; provided, however, that to the extent that the
acceleration of the exercisability of this Option would result in the
disallowance under Section 280G of the Code of tax deductions which would
otherwise be available to the Company or its Affiliates, or in liability of
Optionee or any person obtaining rights in the Option under Section 8 for any
excise tax under Section 4999 of the Code, such unvested portion of this Option
will not immediately vest unless the Company receives prior written consent from
Optionee at least thirty (30) days prior to the Change of Control. In the event
of a Change of Control, the Company may, in its discretion, do one or more of
the following: (i) shorten the period during which this Option is exercisable
(provided it remains exercisable for at least 30 days after the date on which
notice of such shortening is given to Optionee); (ii) arrange to have the
surviving or successor entity assume this Option or grant a replacement option
with appropriate adjustments in the option price and adjustments in the number
and kind of securities issuable upon exercise so that the Option or its

                                       6
   7
replacement represents the right to purchase the shares of stock, securities or
other property (including cash) as may be issuable or payable as a result of a
Change of Control with respect to or in exchange for the number of Membership
Interests purchasable and receivable upon the exercise of this Option had such
exercise occurred in full prior to such Change of Control; or (iii) cancel this
Option upon the payment to Optionee in cash, with respect to such portion of
this Option to the extent then exercisable (including any portion of this Option
as to which the exercise has been accelerated in accordance with this Section
10(d)), of an amount that is the equivalent of the Option Spread at the
effective time of the Change of Control.

         To the extent that the foregoing adjustments relate to securities of
the Company, such adjustments shall be made by the Company, whose determination
shall be conclusive and binding on all persons.
