                              AVID TECHNOLOGY, INC.
                      1998 PROFIT SHARING PLAN DESCRIPTION




PURPOSE OF THE PLAN

The  purpose of the Profit  Sharing  Plan is to reward  all Avid  employees  for
improving Company performance as measured by Return on Invested Capital (ROIC).


ELIGIBILITY TO PARTICIPATE IN THE PLAN

All regular Avid  employees  who are not already  covered by a sales  commission
plan or the Executive  Variable  Compensation  Plan are eligible to participate.
Employees hired after January 1, 1998 but before October 1, 1998 are eligible to
participate  on a prorated  basis.  Employees  hired on or after October 1, 1998
will be eligible to participate in the Plan beginning January 1, 1999. Temporary
employees are excluded from the Plan. However, if a temporary employee transfers
to a regular  position  prior to October 1, 1998,  he/she will  participate on a
prorated basis. Rehires will be treated as new employees under the Plan.


OPERATION OF THE PLAN

At target  performance  the Plan pays a percentage of the 1998 base salary which
has been paid to  participants  during the year while a Plan  participant.  This
includes vacation,  personal time, sick time, and holiday time BUT NOT overtime,
shift  differential,  or other  premium pay. The Plan pays more for  performance
above target.

Performance  is measured by Avid's  1998 ROIC.  In 1998 Avid's ROIC  performance
will be evaluated against a peer group of other  publicly-traded high technology
companies.  The Standard & Poor's High  Technology  Composite will comprise this
peer group.  The 1998 Plan target award is set at a percentile  ROIC of the peer
group selected by the Board of Directors.

WHAT IS ROIC?

ROIC is calculated as shown below:

                             OPERATING INCOME
          ROIC = --------------------------------------------------
                  Total Non-Cash Assets MINUS Interest-Bearing Debt

Operating Income (the numerator) is defined as profit from operations.

Invested  Capital  (the  denominator)  is defined as total  assets less cash and
debt.


CHANGES IN STATUS

Individual awards will be prorated under the following circumstances:

      1) Any salary changes throughout the year are automatically prorated since
      Profit Sharing is calculated on the actual base salary paid during 1998.

      2) If a participant  is hired after January 1, his/her Profit Sharing will
      be  automatically  prorated for that portion of the fiscal year worked for
      Avid since it will be  calculated  on actual base salary paid during 1998.
      For example,  if the  participant  is hired July 1, 1998,  his/her  Profit
      Sharing will be based on a half a year's base salary.

      3) If a  participant  transfers  from a  temporary  to a regular  position
      before  October 1, 1998,  his/her Profit Sharing will be calculated on the
      base salary paid after transferring to the regular position.

      4) If a  participant  is on an approved  leave of absence for a portion of
      1998,  his/her  Profit  Sharing will be calculated on the base salary paid
      during  the  year.  This has the  effect  of  prorating  the award for any
      portion of the leave which was unpaid.

      5) If a participant  becomes  disabled and  qualifies  for benefits  under
      Avid's  long-term  disability  plan,  his/her Profit Sharing award will be
      calculated  on the  base  salary  paid  while on the  Avid  payroll  as an
      employee.

      6) If a participant  is laid off by Avid, the Profit Sharing award will be
      calculated  on the base  salary  paid  through  the  effective  employment
      termination  date.  In this case,  the  payout may not exceed  100% of the
      prorated target award.

      7) If a  participant  dies while in Avid  employment,  the Profit  Sharing
      award will be  calculated  on the base salary paid prior to date of death.
      The award will be paid to the surviving spouse, or if none, to the estate.

TIMING OF PLAN PAYOUT

The Plan payout will be determined after audited  financial results for 1998 are
determined and publicly  released,  near the end of January 1999. Plan payout is
expected to occur in February. Employees must be employed by Avid at the time of
actual Plan payout to receive their Plan award,  unless  eligible for a prorated
award as described above.  Employees who are on approved leave of absence at the
time of actual Plan payout will be considered to be employed for this purpose.

CHANGES TO THE PLAN

The Company reserves the right at its sole discretion to modify,  amend, revoke,
or suspend the Plan at any time
