CONFIDENTIAL

Mr. Ethan Jacks
c/o Avid Technology, Inc.
Avid Technology Park
One Park West
Tewksbury, MA 01876

Dear Ethan:

      Continuity of management of Avid Technology,  Inc.  ("Avid") is a critical
factor to the continued  growth and success of Avid. The Avid Board of Directors
believes  that it is in the  best  interest  of the  Company  to  reinforce  and
encourage the continued attention and dedication of key members of management to
their assigned duties.

      In  consideration of the mutual promises  contained in this letter,  it is
hereby  agreed that Avid shall  provide to you, and that you shall  receive from
Avid, the benefits set forth in this letter (the "Agreement") if your employment
with  Avid,  and  its  subsidiaries,  is  terminated  during  the  term  of this
Agreement.

1.    Purpose

      This Agreement  establishes certain special  arrangements  relating to the
      termination  of your  employment  with Avid for any reason other than: (i)
      your becoming  totally and  permanently  disabled under the Avid long-term
      disability plan or policy, or (ii) your death.

2.    Term of Agreement

      This Agreement  shall become  effective on the date hereof (the "Effective
      Date")  and  shall  terminate  one  year  thereafter.  The  term  shall be
      automatically  extended for  successive  one-year  periods after the first
      anniversary,  unless 30 days' advance written notice is given by you or by
      Avid terminating this Agreement as of any anniversary date.

3.    Termination of Employment

      Your  employment may be terminated in accordance with any of the following
      paragraphs,  but only upon one (1) month's  advance  written notice (which
      period shall be referred to in this Agreement as the "Notice Period"). The
      expiration of the Notice Period shall be your "Date of Termination."

      (a)  Involuntary  Termination  Without  Cause.  Avid  may  terminate  your
      employment  without Cause (as defined below).  In such an event, you shall
      continue to receive your full base salary during the Notice  Period.  Upon
      your Date of Termination, you shall be entitled to those benefits provided
      under Section 4.

      (b) Involuntary  Termination for Cause. Avid may terminate your employment
      for "Cause" by written  notice  setting  forth the Cause for  termination.
      "Cause"  means a  willful  engaging  in gross  misconduct  materially  and
      demonstrably injurious to Avid or the willful and continued failure by you
      substantially to perform your duties with the Company (other than any such
      failure  resulting from your incapacity due to physical or mental illness)
      after a written demand for substantial  performance is delivered to you by
      the Chief Executive  Officer which  specifically  identifies the manner in
      which the Chief Executive Officer believes that you have not substantially
      performed your duties. "Willful" means an act or omission in bad faith and
      without  reasonable belief that such act or omission was in or not opposed
      to the best interests of Avid. Upon your Date of Termination, you shall be
      entitled only to those benefits provided under Section 5.

      (c)  Voluntary  Termination  without  Good  Reason.  You  may  voluntarily
      terminate your employment  without Good Reason (as defined below). In such
      an event,  you shall  continue  to  receive  your  full  base  salary  and
      Employment  Benefits during the Notice Period provided you  satisfactorily
      perform your duties during the Notice  Period,  unless you are relieved of
      those duties by Avid. Upon your Date of Termination, you shall be entitled
      only to those benefits provided under Section 5.

      (d) Voluntary  Termination with Good Reason. You may voluntarily terminate
      your employment  with Good Reason.  "Good Reason" shall mean a significant
      diminution  in your  duties or  responsibilities  that  results in your no
      longer  serving as Vice  President,  Business  Development  & Chief  Legal
      Officer of the Company.  In such an event,  you shall  continue to receive
      your full base salary and  Employment  Benefits  during the Notice Period,
      provided you satisfactorily  perform your duties during the Notice Period,
      unless  you are  relieved  of those  duties  by Avid.  Upon  your  Date of
      Termination,  you  shall be  entitled  to those  benefits  provided  under
      Section 4.

4.    Special Severance Benefits

      If your employment with Avid is  involuntarily  terminated by Avid without
      Cause  pursuant  to Section  3(a) or by you for Good  Reason  pursuant  to
      Section 3(d), then you shall receive the following benefits as long as you
      continue to comply with your obligations under Section 8 of this Agreement
      and any  Invention  and  Nondisclosure  Agreement  (or similar  agreement)
      between you and the Company:

      (a) Your base salary  shall be  continued in effect for a period of twelve
      (12)  months  from  your  Date of  Termination  (hereinafter  called  your
      "Severance  Pay Period").  Avid will also pay you,  during the  thirteenth
      through  twenty-fourth  months  following  termination,  on a semi-monthly
      basis,  the  amount  by which  your  monthly  base  salary  at the Date of
      Termination exceeds your monthly compensation from your new employer;

      (b) You will  receive  incentive  compensation  payments  in an  aggregate
      amount  equal to your  target  award  for the  calendar  year  immediately
      preceding  the  calendar  year in which your Date of  Termination  occurs,
      payable in equal semi-monthly  installments during the 12 months following
      the  Date of  Termination.  You  shall  have  no  right  to any  pro-rated
      incentive compensation in respect of the year of termination;

      (c) Notwithstanding any provision to the contrary in any Avid stock plan,
      or under the terms of any grant,  award  agreement or form for  exercising
      any right  under any such  plan,  any stock  options or  restricted  stock
      awards held by you as of the Date of Termination shall become  exercisable
      or vested,  as the case may be, as to an additional number of shares equal
      to the number that would have been  exercisable or vested as of the end of
      the 12 month period immediately following the Date of Termination. Nothing
      in this  Agreement  shall be  construed  to extend the time period  within
      which any option may be  exercised  beyond  the  period  specified  in the
      applicable stock plan or under the terms of any grant,  award agreement or
      form for exercising any right under any such plan;

      (d) During the Severance Pay Period, in the event you elect to continue to
      participate  in the  Company's  medical  and  dental  plans to the  extent
      permitted   under  COBRA,   the  Company   shall  pay  the  cost  of  such
      participation; and

      (e) You shall be entitled to full executive  outplacement  assistance with
      an agency selected by Avid.

5.    Benefits Upon Voluntary Termination without Good Reason or Termination
      for Cause.

      Upon your  termination  for Cause in accordance  with Section 3(b) or your
      termination  without  Good Reason in  accordance  with Section  3(c),  all
      benefits under this Agreement will be void. In such an event, you shall be
      eligible for the benefits (if any) provided in  accordance  with the plans
      and  policies  of Avid  which are then  applicable  to  employees  of Avid
      generally.

6.    Confidentiality.

      The  provisions  of the Employee  Invention and  Non-Disclosure  Agreement
      between you and Avid shall continue in full force and effect following any
      termination of employment.

7.    Relationship to Change-in-Control Agreement, Etc.

      (a)  In  the  event  you  become   entitled  to  any  benefits  under  any
      Change-in-Control   Employment   Agreement  between  you  and  Avid,  such
      Change-in-Control  Employment  Agreement  shall control and this Agreement
      shall be void and of no further force or effect.

      (b)  Except  as  expressly  set  forth in  Section  7(a),  this  Agreement
      supersedes  all prior  agreements  with Avid related to the subject matter
      hereof and the special  severance  benefits  provided under this Agreement
      are to be  provided  instead  of any other  Avid  severance  arrangements.
      Avid's  severance  policies and  practices  are  superseded  except to the
      extent  incorporated  herein.   Notwithstanding  the  foregoing,   nothing
      contained in this  Agreement  shall have any affect upon your rights under
      any tax qualified  "pension  benefit plan", as such term is defined in the
      Employee  Retirement  Income Security Act of 1974, as amended (ERISA);  or
      any other "welfare benefit plan" as defined in ERISA,  including by way of
      illustration and not limitation,  any medical surgical or  hospitalization
      benefit coverage or long-term  disability  benefit coverage;  or under any
      deferred compensation or equity incentive arrangement, including by way of
      illustration and not limitation,  any stock incentive plan,  non-qualified
      pension plan, or phantom stock plan.

8.    Covenant Not to Compete and Not to Solicit.

      (a) During the term of this  Agreement,  and for a period of two (2) years
      following the termination of your employment for any reason, you agree you
      will not engage in any business  (whether as an owner,  partner,  officer,
      director,  employee,  consultant or otherwise, except as the holder of not
      more than 1% of the  outstanding  stock of a  publicly-held  company) that
      competes or plans to compete with Avid in the business of the development,
      manufacture,  promotion,  distribution  or sale of digital film,  video or
      audio editing,  special effects or newsroom automation systems or products
      or any other  business  in which Avid is engaged or plans to engage at the
      time of your  termination.  Without  limiting the  foregoing,  during such
      period you shall not be employed by or otherwise  serve as a consultant to
      Accom/Abekas/Scitex Digital Video, Adobe, Autodesk/Discreet Logic/DVision,
      Carlton Communications/Quantel,  FAST Technology, Media 100, MGI, Pinnacle
      Systems/Truevision,  Play Systems, SADIE, Sonic Solutions, Tektronix Video
      and Networking  Division/Grass Valley Group, or any of the subsidiaries or
      affiliates of the foregoing companies.

      (b) You also  agree  that,  for a period of two (2) years from the date of
      your termination,  you will not, either directly or indirectly  through an
      agency,  new employer or otherwise,  solicit the employment of (or solicit
      to engage as an independent  contractor or  consultant)  any person who at
      any time during the one year preceding such  solicitation  was an employee
      or independent contractor of Avid or any Avid affiliate.

      (c) If any  restriction  in  this  Section  8 is  found  by any  court  of
      competent jurisdiction to be unenforceable because it extends for too long
      a period of time or over too great a range of activities or in too broad a
      geographic  area, it shall be  interpreted to extend only over the maximum
      period of time,  range of activities or geographic area as to which it may
      be enforceable.

      (d) The  restrictions  contained in this Section 8 are  necessary  for the
      protection of the business and good will of Avid and are considered by you
      to be  reasonable  for such  purpose.  You agree  that any  breach of this
      Section  8  will  cause  Avid  substantial  and  irrevocable  damage  and,
      therefore,  in the event of any such  breach,  in  addition  to such other
      remedies  which  may be  available,  Avid  shall  have  the  right to seek
      specific performance and injunctive relief.

9.    Notice.

      Notice  required or permitted under this Agreement shall be in writing and
      shall be deemed to have been given when  delivered or mailed by the United
      States certified mail,  return receipt  requested,  postage prepaid,  in a
      properly  addressed  envelope.  Notices to Avid shall be  addressed to the
      Corporate Secretary.

10.   Modification; Successors.

      No provision of this  Agreement  may be waived,  modified,  or  discharged
      except  pursuant  to a written  instrument  signed  by you and Avid.  This
      agreement  is  binding  upon any  successor  to all or  substantially  all
      business or assets of Avid.

11.   Indemnification.

      The Company will indemnify you to the extent set forth in the  Certificate
      of  Incorporation  and By-laws of the  Company  for all acts or  omissions
      occurring during the period of your employment.

12.   Miscellaneous.

      This  agreement  shall be governed by and construed  under the laws of the
      Commonwealth  of  Massachusetts.  The  validity or  enforceability  of any
      provision  hereof shall not affect the validity or  enforceability  of any
      other  provision  hereof.  This  Agreement  may be executed in one or more
      counterparts,  each of which  together  will  constitute  one and the same
      instrument.

Accepted and Agreed                       Sincerely,
to this date of

January 24, 2000                          Avid Technology, Inc.
