unless sooner terminated pursuant to Section 12 hereof.
 
7.  DURATION OF OPTION
 
    (a) The proper officers of CCCISG shall execute and deliver to each Grantee
a written Stock Option Agreement which shall be executed by the Grantee and

                                      A-2

Stock Option Agreement. Notwithstanding the maximum 10-year term, all Options
granted under the Plan shall expire sooner as follows:
 
        (i) If the employment of a Grantee is terminated for any reason other
    than as specified in subparagraphs (ii), (iii) or (iv) hereof, then the
    Option will expire on the thirtieth (30th) day after the date of such
    termination.
 
        (ii) Subject to subparagraphs (iii) and (iv) hereof, if the Grantee
    retires from the CCCISG Companies at an age at which such Grantee would be
    eligible to receive benefits under the Federal Social Security Act or
    retires with the consent of the Board of Directors of CCCISG, the Option
    will expire three (3) months after the date of termination.
 
       (iii) Subject to subparagraph (iv) hereof, if a Grantee becomes Disabled
    while serving in his capacity as an Employee, the Option will expire twelve
    (12) months after the date of termination of the Employee's employment as
    the result of having become Disabled.
 
        (iv) If a Grantee dies while serving as an Employee, or if the Grantee
    dies within twelve (12) months after termination of service in accordance
    with subparagraph (iii) hereof, or if the Grantee shall die within three (3)
    months after termination of service in accordance with subparagraph (ii)
    hereof, the Option will expire twelve (12) months after the date of death.
 
    Following termination of employment for any reason, no Option shall become
exercisable except to the extent such Option was exercisable on the date of such
termination.
 
8.  EXERCISE OF OPTION
 
    (a) Options shall be exercised by delivering or mailing at the time of
exercise to the Secretary of CCCISG or his/her designee:
 
        (i) A notice, in the form and manner prescribed by the Committee,
    specifying the number of shares to be purchased under an Option, and
 
        (ii) Payment in full of the Exercise Price, and any associated
    withholding tax, for the Shares so purchased by (1) a money order, cashiers
    check or certified check payable to CCCISG, (2) shares of Common Stock owned
    by the Grantee (duly endorsed), or (3) such other form of payment as shall
    be determined by the Committee to be acceptable. Any shares delivered to
    CCCISG as payment for Shares upon exercise of the Option shall be valued at
    their fair market value as of the date of exercise of the Option as
    determined by (A) reference to prices quoted on NASDAQ National Market, or
    such other public exchange or market designated by the Committee, for the
    Common Stock or, (B) if no such quotation exists, as determined by the
    Committee in its sole discretion.
 
    (b) All Options granted under the Plan shall be subject to a vesting
schedule, which shall be determined in the discretion of the Committee.
 
    (c) No Option shall be exercisable in whole or in part and no certificates
representing Shares subject to the Option shall be delivered at any time that
CCCISG shall determine that the satisfaction of withholding tax or other
withholding liabilities is necessary or desirable, unless and until such
withholding shall have been effected.
 
    (d) Options shall be exercisable only with respect to whole Shares and shall
not be exercisable with respect to fractional Shares.
 
9.  ADJUSTMENT OF AND CHANGES IN THE STOCK
 
    (a) In the event that the shares of Common Stock of CCCISG shall be changed
into or exchanged for a different number or kind of shares of stock or other
securities of CCCISG or of another corporation (whether by reason of merger,
consolidation, recapitalization, reclassification, split-up, combination of
 
                                      A-3
<PAGE>
shares, or otherwise), or if the number of shares of Common Stock of CCCISG
shall be increased through a stock split or the payment of a stock dividend,
then there shall be substituted for or added to each share of Common Stock of
CCCISG theretofore appropriated or thereafter subject or which may become
subject to an Option under the Plan, the number and kind of shares of stock or
other securities into which each outstanding share of Common Stock of CCCISG
shall so be changed, or for which each such share shall be exchanged, or to
which each such share shall be entitled, as the case may be. Outstanding Options
shall also be amended as to price and other terms if necessary to reflect the
foregoing events. In the event there shall be any other change in the number or
kind of the outstanding shares of Common Stock of CCCISG or any stock or other
securities into which such Common Stock shall have been changed, or for which it
shall have been exchanged, then if the Committee shall, in its sole discretion,
determine that such change equitably requires an adjustment in any Option
theretofore granted or which may be granted under the Plan, such adjustment
shall be made in accordance with such determination.
 
    (b) No right to purchase fractional shares shall result from any adjustment
in Options pursuant to this Section 9. In case of any such adjustment, the
shares subject to the option shall be rounded down to the nearest whole share.
Notice of any adjustment shall be given by CCCISG to each Grantee which shall
have been so adjusted and such adjustment (whether or not notice is given) shall
be effective and binding for all purposes of the Plan.
 
    (c) In the event CCCISG is a party to a merger or other reorganization,
outstanding options shall not be affected if CCCISG is the surviving
corporation. If CCCISG is not the surviving corporation, outstanding options
subject to the agreement of merger or reorganization shall either be continued
by the surviving corporation at a comparable economic value, or a cash
settlement shall be provided to optionholders for all vested and unvested
options.
 
10. ISSUANCE OF SHARES OF COMMON STOCK
 
    Upon receipt of the notice of exercise and payment of the Exercise Price,
CCCISG shall, subject to the provisions of Section 8(c), issue to the Grantee a
certificate or certificates for the Shares purchased, without charge to him for
issue or transfer tax. Until the issuance of such certificates, no right to vote
or receive dividends or other distributions nor any other rights as a
stockholder of CCCISG shall exist with respect to Shares receivable
notwithstanding the exercise of the Option. Except as provided in Section 9, no
adjustment shall be made for distribution or other rights for which the record
date is prior to the date a Common Stock certificate is issued.
 
11. TRANSFERABILITY OF OPTION
 
    Each Option shall be transferable only by will or the laws of descent and
distribution and shall only be exercisable by the Grantee during his or her
lifetime.
 
12. AMENDMENT OR TERMINATION OF THE PLAN
 
    (a) The Committee may amend the Plan from time to time in such respects as
the Committee may deem advisable. Any such amendment may apply to any Options
that were granted before the date such amendment is adopted, but that have not
been exercised as of the date such amendment is adopted, provided that no such
amendment shall change the number of Shares subject to, or the Exercise Price
of, any such Option. No such amendment shall affect any Option that has been
exercised before the date such amendment is adopted.
 
    (b) The Committee may at any time terminate the Plan. Any such termination
of the Plan shall not affect Options previously granted and such Options shall
remain in full force and effect as if the Plan had not been terminated.
 
                                      A-4
<PAGE>
13. AGREEMENT AND REPRESENTATIONS OF GRANTEE
 
    As a condition to the exercise of any portion of an Option, CCCISG 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 otherwise distribute such Shares. The
Shares shall not be offered, sold, transferred, pledged or otherwise disposed of
by the person exercising the Option in the absence of registration, or the
availability of an exemption from registration, under the Securities Act of
1933. No such offer, sale, transfer, pledge or other disposition may be made
without prior written opinion of counsel for CCCISG that such offer, sale,
transfer, pledge or other disposition will not violate the Securities Act of
1933 or other applicable securities law, rule or regulation of any jurisdiction.
 
14. TAX CONSIDERATIONS
 
    All options granted under the Plan are not intended to qualify, and shall
not be treated as, "incentive stock options" as such term is defined in Section
422 of the Internal Revenue Code of 1986.
 
15. RESERVATION OF SHARES
 
    CCCISG, during the term of this Plan, shall at all times reserve and keep
available, and shall seek or obtain from any regulatory body having jurisdiction
any requisite authority in order to sell, such number of Shares as shall be
sufficient to satisfy the requirements of the Plan. Inability of CCCISG to
obtain from any regulatory body having jurisdiction the authority deemed by
CCCISG's counsel to be necessary for the lawful sale of any Shares hereunder
shall relieve CCCISG of any liability in respect of the failure to sell such
Shares as to which such requisite authority shall not have been obtained.
 
16. NOTICE
 
    All notices delivered pursuant to the Plan shall be in writing, delivered by
hand or by first class certified mail, return receipt requested, postage prepaid
as specified in the Stock Option Agreement.
 
17. GOVERNING LAW
 
    The Plan shall be construed and its provisions enforced and administered in
accordance with the laws of the State of Delaware, except to the extent that
such laws may be superseded by any Federal law.
