Dear Mr. Dewar:

This letter confirms the terms of your employment by Activision, Inc.
("Employer").

1.         TERM

           (a)  The initial term of your employment under this agreement shall
commence on September 1, 1997 and shall expire on August 31, 1998, unless
earlier terminated as provided below (the "initial period").

           (b)  Employer shall have the irrevocable option to extend the term
of this agreement beyond the initial period for three additional successive
one year periods.

           (c)  The options granted to Employer in Paragraph 1(b) of this
agreement will be exercised by Employer by written notice given to you at
least six (6) months prior to the expiration of the initial period, the first
annual option period or the second annual option period, as applicable.

2.         COMPENSATION

           (a)  In full consideration for all rights and services provided by
you under this agreement, you shall receive an annual base salary of L135,000
during the initial period.  If Employer exercises its option pursuant to
Paragraph 1(b) with respect to the first annual option period, your annual
base salary shall be L142,500 during such first annual option period.  If
Employer exercises its option pursuant to Paragraph 1(b) with respect to the
second annual option period, your annual base salary shall be L150,000 during
such second annual option period.  If Employer exercises its option pursuant
to Paragraph 1(b) with respect to the third annual option period, your annual
base salary will be L157,500 during such third annual option period.

           (b)  Base salary payments shall be made in accordance with
Employer's then prevailing payroll policy.  Each base salary referred to in
Paragraph 2(a) shall constitute

                                  Page 1                                06/25/99


your minimum base salary during the applicable period, and your base salary
may be increased above the minimum at any time if Employer's Board of
Directors (or the Compensation Committee of such Board of Directors), in its
sole and absolute discretion, elects to do so.  In the event of an increase
in your base salary beyond the applicable minimum base salary for a
particular period, such increased base salary shall then constitute your
minimum base salary for all subsequent periods under this agreement.

           (c)  Notwithstanding anything to the contrary set forth above, but
subject to the right of termination granted to you pursuant to Paragraph
10(b), Employer shall not be required to actually use your services, and
payment of your base salary during the applicable period of your employment
under this agreement will discharge Employer's obligations to you hereunder.
Such payment, however, will not discharge your obligations to Employer
hereunder.

           (d)  In addition to your base salary, you may be entitled to
receive an annual performance based bonus of up to 60% of your annual base
salary, in compliance with the standard company plans and procedures which is
determined by Employer's senior management and Board of Directors (or the
Compensation Committee of such Board of Directors) based on a number of
factors including the achievement of specific corporate sales, profitability
and return on equity goals, as well as a discretionary component which will
based upon your performance, achievement of objectives, and contribution to
the success of the corporate goals and objectives.

           (e)  You also are being granted, under Employer's existing or
modified stock option plan, options to purchase 7,500 shares of Employer's
common stock. Such options are in addition to the stock options previously
issued to you by Employer.  The 7,500 options will be issued on the
commencement date of your employment under this agreement and will vest
ratably over five years, with one fifth (1/5) of the amount granted vesting
at the end of each such year.  Such options will have an exercise price that
will be the market price of such common stock on the date the options are
issued and will be governed in all other respects by Employer's stock option
plan in effect at the time of grant.  You also shall be eligible to receive
additional options under the company's existing or modified stock option
plan, if Employer's Board of Directors (or the Compensation Committee of such
Board of Directors), in its sole and absolute discretion, determines that the
grant to you of additional options is appropriate.

           (f)  Employer and you acknowledge that, as of the execution date
of this agreement, you have accrued but have not yet been paid bonus
compensation in the amount of L10,903 for services previously rendered by you
to Employer.  Employer and you agree that such L10,903 bonus shall not
actually be paid to you but instead shall be applied as a reduction of the
L50,000 loan previously made to you by Employer.  In addition, the
outstanding loan balance of L39,097 shall automatically be reduced by
L1,629.04 per month on the last day of each month, commencing on September
30, 1997,

                                  Page 2                                06/25/99


provided that you continue to be employed by Employer under this agreement on
the applicable reduction date.

position with Employer. You shall observe all reasonable rules and
regulations adopted by Employer in connection with the operation of its
business and carry out all instructions of Employer.  You will at all times
perform all of the duties and obligations required by you under this
agreement in a loyal and conscientious manner and to the best of your ability

           During the term of your employment by Employer, you will not
compete in any manner, whether directly or indirectly, as a principal,

agreement.

9.         SERVICES UNIQUE

           You recognize that the services being performed by you under this
agreement are of a special, unique, unusual, extraordinary and intellectual
character giving them a peculiar value, the loss of which cannot be

                                  Page 4                                06/25/99


and in the event of a breach of this agreement by you (particularly, but
without limitation, with respect to the provisions hereof relating to the
exclusivity of your services and the provisions of paragraph 8 of this
agreement), Employer shall, in addition to all other remedies available to
it, be entitled to equitable relief by way of injunction and any other legal

California law.

           (b)  You may terminate your employment under this agreement (i) if
Employer elects to not actually use your services and continues to pay your

otherwise, at any time during a period of one (1) year following such
expiration or termination, offer employment to, or solicit the employment or
engagement of, or otherwise entice away from the employment of Employer or
any affiliated entity, either for your own account or for any other person
firm or company, any person who was employed by Employer or any such
affiliated entity on the last day of your employment under this agreement,
whether or not such person would commit any breach of his or her contract of
employment by reason of his or her leaving the service of Employer or any
affiliated entity.
