the greatest volume of trading in Shares) on the last ten (10) market trading
days prior to the day of determination, as reported in the Wall Street Journal
or any other source the Company considers reliable.

               (b) If the Shares are quoted on the NASDAQ System (but not on the

        for any reason, with or without Cause, including as a result of death or
        disability, this Option shall cease vesting and shall be canceled to the
        extent of the number of Shares as to which this Option has not vested as
        of the date of termination.

               4.1.3 Notwithstanding the other provisions of this Section 4,
        this Option shall become immediately vested and exercisable in full upon

<PAGE>

               4.2.3 In the event of the termination of Optionee's Continuous
        Status as an Employee or Consultant, the exercisability of this Option
        is governed by this Section 4.2 and Section 7 below.

               4.2.4 In no event may this Option be exercised after the date of
        expiration of the term of this Option as set forth in Section 10 below.

        4.3 METHOD OF EXERCISE. This Option shall be exercisable by written
notice in the form attached hereto as EXHIBIT A which shall state the election
to exercise this Option, the number of Shares in respect of which this Option is
being exercised, and such other representations and agreements as to Optionee's
investment intent with respect to such Shares as may be required by the Company.
Such written notice shall be signed by Optionee (or by Optionee's beneficiary or
other person entitled to exercise this Option in the event of Optionee's death
or as a transferee of Optionee under Section 8) and shall be delivered in person
or by certified mail to the Secretary of the Company. The written notice shall
be accompanied by payment of the exercise price as provided in Section 6. This
Option shall be deemed exercised upon receipt by the Company of such written
notice accompanied by the exercise price.

5.      FREELY TRADEABLE SHARES TO BE ISSUED.

        It is contemplated that the Shares to be delivered to Optionee will,
upon transfer by the Company to the name of Optionee, be freely tradeable
without restriction under the Securities Act of 1933, as amended, other than
restrictions imposed under Rule 144 thereunder (or its then equivalent) to the
extent that Optionee may be deemed to be an affiliate of Charter. If for any
reason the Company is unable to deliver such freely tradeable shares to Optionee
promptly upon exercise of this option, the Company shall pay to Optionee upon
such exercise an amount in cash equal to the excess of the Fair Market Value of
the Shares covered by the exercised option (determined without regard to lack of
registration or other similar restrictions which might adversely affect such
value) on the date of exercise over the exercise price for such Shares.

6.      METHOD OF PAYMENT.

        Payment of the exercise price shall be in full at the time of exercise
at the election of Optionee (i) in cash or by check payable to the order of the
Company, (ii) by delivery of Shares already owned by, and in the possession of,
Optionee, having a Fair Market Value equal to the exercise price, (iii) by the
withholding by the Company from the Shares as to which the Option is exercised
of that number of Shares having a Fair Market Value equal to the exercise price
(i.e., a "cashless exercise"), in any case complying with all applicable laws
(including, without limitation, state and federal margin requirements), or any
combination thereof. Shares used to satisfy the exercise price of this Option
shall be valued at their Fair Market Value determined on the date of exercise.

7.      TERMINATION OF CONTINUOUS STATUS AS AN EMPLOYEE OR CONSULTANT.

        In the event of termination of Optionee's Continuous Status as an
Employee or Consultant, this Option shall continue to remain outstanding as to
vested Options (including Options that become vested under Section 4.3) and
shall be canceled as to unvested options

                                     - 4 -
<PAGE>

as provided in Sections 4.1 and 4.2. In the event this Option is partially or
wholly vested on the date of termination of Optionee's Continuous Status as an
Employee or Consultant, the following provisions shall apply:

        7.1 TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP. If Optionee
holds an exercisable portion of this Option on the date his Continuous Status as
an Employee or Consultant terminates (other than as provided in Section 7.2),
Optionee may exercise such portion of this Option until the earlier of (i) its
expiration as set forth in Section 10, and (ii) 90 days after the date of such
termination. If Optionee is not entitled to exercise the entire Option at the
date of such termination, the unexercisable portion of the Option will
automatically be canceled. If Optionee does not exercise the Option within the
time specified above after termination, the Option will expire.

        7.2 DEATH OR DISABILITY OF OPTIONEE. If Optionee holds an exercisable
portion of this Option on the date his death or Disability, Optionee's estate or
beneficiary or a person who acquired the right to exercise the Option by bequest
or inheritance in the event of Optionee's death, or Optionee or Optionee's
representative in the event of Optionee's Disability, may exercise such portion
of this Option until the earlier of (i) its expiration as set forth in Section
10, and (ii) one year after the date of death or Disability. If Optionee is not
entitled to exercise his entire Option at the date of death or Disability, the
unexercisable portion of the Option shall be automatically canceled. If
Optionee, Optionee's representative, Optionee's estate, beneficiary, or a person
who acquired the right to exercise the Option by bequest or inheritance does not
exercise the Option within the time specified above after death or Disability,
the Option will expire.

8.      NON-TRANSFERABILITY OF OPTION.

        8.1 NON-TRANSFERABILITY. This Option may not be transferred in any
manner otherwise than by will or by the laws of descent or distribution or to a
beneficiary designated under this Section 8, and may be exercised during the
lifetime of Optionee only by Optionee. 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 the 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 this Option pursuant
to the assignment. The terms applicable to the assigned portion shall be the
same as those in effect for this 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.

        8.2 DESIGNATION OF BENEFICIARY. Optionee may file a written designation
of a beneficiary who is to receive any portion of this Option that remains
unexercised in the event of the Optionee's death. If Optionee is married and the
designated beneficiary is not the spouse, spousal consent will be required for
the designation to be effective. Optionee may change such designation of
beneficiary at any time by written notice to the Company, subject to the above
spousal consent requirement.

                                     - 5 -
<PAGE>

        8.3 EFFECT OF NO DESIGNATION. If Optionee dies and there is no
beneficiary, validly designated under Section 8.2 and living at the time of the
Optionee's death, the Company will deliver this Option to the executor or
administrator of Optionee's estate, or if no such executor or administrator has
been appointed (to the knowledge of the Company), the Company, in its
discretion, may deliver this Option to the spouse or to any one or more
dependents or relatives of the Optionee, or if no spouse, dependent or relative
is known to the Company, then to such other person as the Company may designate.

        8.4 DEATH OF SPOUSE OR DISSOLUTION OF MARRIAGE. If Optionee designates
his spouse as beneficiary under Section 8.2, that designation will be deemed
automatically revoked if Optionee's marriage is later dissolved. Similarly, any
designation of a beneficiary under Section 8.2 will be deemed automatically
revoked upon the death of the beneficiary if the beneficiary predeceases
Optionee. Without limiting the generality of the preceding sentence, the
interest in this Option of a spouse who has predeceased Optionee or whose
marriage has been dissolved will automatically pass to Optionee, and will not be
transferable by such spouse in any manner, including but not limited to such
spouse's will, nor will any such interest pass under the laws of intestate
succession.

9.      ADJUSTMENT FOR REORGANIZATIONS, STOCK SPLITS, ETC.

        If the outstanding Shares are increased, decreased, changed into, or
exchanged for a different number or kind of shares or securities of Charter or a
successor entity, or for other property (including, without limitation, cash)
through reorganization, recapitalization, merger, reclassification, stock
dividend, stock split or reverse stock split, spin off, or other similar
transaction, an appropriate and proportionate adjustment shall be made in the
maximum number and kind of membership interests, shares, or other securities
covered by this Option. Any such adjustment in this Option will be made without
change in the aggregate purchase price under this Option but with a
corresponding adjustment in the price for each unit or share or any security
covered by this Option. Such adjustment will be made by the Company, whose
determination in that respect will be final, binding, and conclusive.

10.     TERM OF OPTION.

        This Option may not be exercised more than ten (10) years from the date
of grant of this Option, and may be exercised during such term only in
accordance with the terms of this Option.

11.     WITHHOLDING OF TAXES.

        The Company shall have the right to take whatever steps the Company
deems necessary or appropriate to comply with all applicable federal, state,
local, and employment tax withholding requirements, and the Company's
obligations to deliver Shares upon the exercise of this Option shall be
conditioned upon compliance with all such withholding tax requirements. Without
limiting the generality of the foregoing, the Company shall have the right to
withhold taxes from any other compensation or other amounts which it may owe to
Optionee, or to require Optionee to pay to the Company, the amount of any taxes
which the Company may be required to withhold with respect to such Shares.
Without limiting the generality of the foregoing, the Company in its discretion
may authorize Optionee to satisfy

                                     - 6 -
<PAGE>

all or part of any withholding tax liability by (a) having the Company withhold
from the Shares which would otherwise be issued on the exercise of this Option
that number of Shares having a fair market value as of the date the withholding
tax liability arises equal to or less than the amount of the withholding tax
liability, or (b) delivering to the Company previously-owned and unencumbered
shares of the Common Stock of the Company having a Fair Market Value as of the
date the withholding tax liability arises equal to or less than the amount of
the withholding tax liability.

12.     GOVERNING LAW.

        THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE
STATE OF DELAWARE APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY IN
DELAWARE, WITHOUT REGARD TO THE CONFLICTS OF LAW PROVISIONS OF DELAWARE OR ANY
OTHER JURISDICTION.

13.     NOTICES.

writing by express courier or by postage prepaid, United States registered or
certified mail, return receipt requested, to the address set forth below or to

agreement to sell, in a single or related series of transactions (other than in

        employee remains an Eligible Individual shall occur only when the
        Optionee is no longer an Eligible Individual and (y) or with respect to
        Optionee who is receiving severance payment shall occur when such
        payments cease, provided Optionee enters into a release in the form
        acceptable to the Company.

2. Section 5.4 of the Plan is amended in its entirety to read as follows:

        5.4 Vesting. Subject to Section 6.4, each Option shall entitle the
        Eligible Individual to purchase, in whole at any time or in part from
        time to time, 25% of the total number of Shares covered by the Option as
        of the first anniversary of the date of grant and an additional 25% of
        the total number of Shares covered by the Option after the expiration of
        each of the second, third and fourth anniversaries of the date of grant
        while the Optionee is an Eligible Individual; provided however, that
        Options (i) may vest in such other installments (which need not be
        equal) and at such times as may be designated by the Committee in its
        discretion and set forth in the Agreement, and (ii) unless the Committee
        provides otherwise in the Agreement, shall continue to vest only while
        the Optionee is an Eligible Individual. Notwithstanding the foregoing,
        the vesting of any Option shall continue during the period the Optionee
        is receiving severance payments provided Optionee enters into a release
        in the form acceptable to the Company. The Committee may, in its
        discretion, permit the continued vesting or accelerate the vesting of
        any Option or portion thereof at any time.

3. Section 6.1 is amended by replacing the first sentence thereof with the
following:

        Notwithstanding any other provision contained in this Plan, in the event
        of a Change in Control, any unvested Options issued under this Plan to
        an Optionee who is an employee of the Company or a Subsidiary or
        Affiliate of the Company shall vest and become fully exercisable,
        subject to the provisions of Section 12.2, upon (i) the termination by
        the Company, Subsidiary, or Affiliate of the Optionee's employment other
        than for Cause or (ii) the termination of the Optionee's employment for
        Good Reason, during the 12-month period following the Change in Control.

The terms of the Plan shall remain in full force and effect without modification
or amendment except as expressly set forth herein.
