To be attached to and form part of Policy No. 8125-64-60E
Issued to: Richardson Electronics, Ltd.

It is agreed that:

     1.   The following is added to this coverage section:

     Investigative Costs Coverage
     Insuring Clause 4

     The Company shall pay on behalf of the Insured Organization
all Investigation Costs which such Insured Organization becomes
legally obligated to pay on account of any Shareholder Derivative
Demand first made during the Policy Period or, if exercised, the
Extended Reporting Period, for Wrongful Act committed or
attempted, by an Insured Person before or during the Policy
Period.

     2.   Subsection 5 Exclusions Applicable to Insuring Clauses 1 and
     2, is amended by deleting the subsection heading in its
     entirety and inserting the following:

     Exclusions Applicable to Insuring Clauses 1, 2 and 4

     3.   Subsection 8, Limit of Liability, Deductible and Coinsurance,
     is amended as follows:

               a.   The following is added to paragraph two:

                    The Company's maximum liability for all Investigative
          Costs covered under Insuring Clause 4 on account of all
          Shareholder Derivative Demands first made during the
          same Policy Period shall be $250,000.  This is a
          sublimit which further limits and does not increase the
          Company's maximum liability under this coverage section
          as set forth in Item 2(B) of the Declarations for this
          coverage section.

               b.   The following is added to paragraph three:

          Costs covered under Insuring Clause 4.

     4.   Subsection 11, Defense and Settlement, is amended for
     purposes of coverage under Insuring Clause 4 by deleting the
     first paragraph in its entirety and inserting the following:

          Subject to this subsection, it shall be the duty of the
     Insured Organization and not the duty of the Company to
     investigate and evaluate any Shareholder Derivative Demand.

     5.   Subsection 18, Definitions, is amended by adding the
     following:

          Investigation Costs means reasonable costs, charges, fees
     (including but not limited to attorneys' fees and experts'
     fees) and expenses (other than regular or overtime wages,
     salaries or fees of the directors, officers or employee of
     the Insured Organization) incurred by the Insured
     Organization (including its board of directors) in connection
     with the investigation or evaluation of any Shareholder
     Derivative Demand.

          Shareholder Derivative Demand means any written demand, by
     one or more shareholders of an Insured Organization, upon the
     board of the directors of such Insured Organization, to bring
     a civil proceeding in a court of law against any Insured
     Person for a Wrongful Act committed attempted or allegedly
     committed or attempted by an Insured Person before or during
     the Policy Period.

     6.   For purposes of coverage under Insuring Clause 4 only, 
               a.   all references in this coverage section to Loss or
          Defense Costs shall only mean Investigative Costs; and
               b.   all references in this coverage section to Claim or to
          Claim against any Insured Person shall only mean any
          Shareholder Derivative Demand.

All other terms and conditions remain unchanged.
