Item 5.  Other Events.

         On September  21, 2001,  the Board of  Directors  of  California  Micro
Devices  Corporation  (the  "Company")  declared a dividend  distribution of one
"Right" for each  outstanding  share of common stock (the "Common Stock") of the
Company to  shareholders  of record at the close of business on October 12, 2001
(the "Record Date").  Except as set forth below,  each Right,  when exercisable,
entitles the registered  holder to purchase from the Company one  one-thousandth
of a  share  of a  new  series  of  preferred  stock,  designated  as  Series  A
Participating  Preferred  Stock  (the  "Preferred  Stock"),  at a price of Fifty
Dollars  ($50.00)  per one  one-thousandth  of a share (the  "Purchase  Price"),
subject to adjustment.  The description and terms of the Rights are set forth in
a Rights  Agreement  (the  "Rights  Agreement")  between  the Company and Mellon
Investor Services LLC, as "Rights Agent."

         Initially, the Rights will be attached to all Common Stock certificates
representing  shares then outstanding,  and no separate Rights certificates will
be  distributed.   The  Rights  will  separate  from  the  Common  Stock  and  a
"Distribution Date" will occur upon the earliest of the following:  (i) a public
announcement that a person,  entity or group of affiliated or associated persons
and/or entities (an "Acquiring  Person") has acquired,  or obtained the right to
acquire,   beneficial  ownership  of  fifteen  percent  (15%)  or  more  of  the
outstanding shares of Common Stock (other than (A) as a result of repurchases of
stock by the Company or certain  inadvertent actions by institutional or certain
other  shareholders,  (B) the  Company,  any  subsidiary  of the  Company or any
employee  benefit  plan of the  Company  or any  subsidiary,  (C)  Kern  Capital
Management,  LLC (with its affiliates and associates,  "Kern"),  which currently
owns in excess of fourteen  percent  (14%) of the  outstanding  shares of Common
Stock,  so long as Kern does not (x)  beneficially  own more than twenty percent
(20%) of the outstanding  shares of Common Stock or (y) state any intention,  or
reserve the right,  to control or influence  the  management  or policies of the
Company  (although  this  exception  will  pertain  only  until  Kern  first has
beneficial  ownership of less than  thirteen  percent  (13%) of the  outstanding
shares of Common Stock), (D) Chan Desaigoudar  (together with his affiliates and
associates,  "Chan"),  who currently owns in excess of fifteen  percent (15%) of
the  outstanding  shares  of  Common  Stock,  so long as the  percentage  of the
outstanding  shares of Common Stock beneficially owned by Chan does not increase
above  the  percentage  beneficially  owned  by Chan on the  date of the  Rights
Agreement  (other than as the result of a  reduction  in the number of shares of
outstanding  Common  Stock),  and (E) certain  other  instances set forth in the
Rights Agreement);  or (ii) ten (10) business days (unless such date is extended
by the Board of  Directors)  following  the  commencement  of a tender  offer or
exchange  offer which would result in any person,  entity or group of affiliated
or associated  persons and/or entities becoming an Acquiring Person (unless such
tender offer or exchange offer is a Permitted Offer (defined below)).

         Until the Distribution Date (or earlier redemption or expiration of the
Rights,  if applicable),  (i) the Rights will be evidenced by  certificates  for
Common Stock and will be transferred  only with such Common Stock  certificates,
(ii) new Common Stock  certificates  issued after the Record Date upon transfers
or new issuances of the Common Stock will contain a notation  incorporating  the
Rights  Agreement  by  reference  and (iii) the  surrender  for  transfer of any
certificates  for outstanding  Common Stock will also constitute the transfer of
the Rights  associated with such Common Stock. As soon as practicable  following
the  Distribution  Date,  separate  certificates  evidencing the Rights ("Rights
Certificates") will be mailed to holders of


                                       2



record of the Common Stock as of the close of business on the Distribution Date,
and the separate Rights Certificates alone will evidence the Rights.

         The Rights are not exercisable until the Distribution  Date. The Rights
will expire on the earliest of (i) September 24, 2011,  (ii)  consummation  of a
merger transaction with a person,  entity or group who (x) acquired Common Stock
pursuant  to a  Permitted  Offer (as  defined  below) and (y) is offering in the
merger the same price per share and form of consideration  paid in the Permitted
Offer or (iii)  redemption or exchange of the Rights by the Company as described
below.

         The number of Rights  associated  with each share of Common Stock shall
be proportionately adjusted to prevent dilution in the event of a stock dividend
on, or a subdivision,  combination or reclassification of, the Common Stock. The
Purchase  Price  payable,  and the number of one  one-thousandths  of a share of
Preferred Stock or other securities or property  issuable,  upon exercise of the
Rights are subject to  adjustment  from time to time to prevent  dilution (i) in
the  event  of  a  stock   dividend  on,  or  a   subdivision,   combination  or
reclassification  of the Preferred Stock,  (ii) upon the grant to holders of the
Preferred  Stock of  certain  rights,  options  or  warrants  to  subscribe  for
Preferred Stock, certain convertible securities or securities having the same or
more favorable rights, privileges and preferences as the Preferred Stock at less
than  the  current  market  price  of the  Preferred  Stock  or  (iii)  upon the
distribution  to holders of the Preferred  Stock of evidences of indebtedness or
assets  (excluding  regular quarterly cash dividends out of earnings or retained
earnings)  or of  subscription  rights,  options or  warrants  (other than those
referred to above).  With certain  exceptions,  no  adjustments  in the Purchase
Price will be required until cumulative  adjustments require an adjustment of at
least one percent (1%) in such Purchase Price.

         In the event that,  after the first date of public  announcement by the
Company or an  Acquiring  Person that an Acquiring  Person has become such,  the
Company  is  involved  in a merger  or other  business  combination  transaction
(whether or not the Company is the surviving corporation) or fifty percent (50%)
or more of the Company's assets or earning power are sold (in one transaction or
a series of transactions), proper provision shall be made so that each holder of
a Right  (other than an Acquiring  Person)  shall  thereafter  have the right to
receive,  upon the exercise  thereof at the then current  Purchase  Price,  that
number of shares of common stock of either the Company,  in the event that it is
the surviving corporation of a merger or consolidation, or the acquiring company
(or,  in the  event  there is more than one  acquiring  company,  the  acquiring
company   receiving  the  greatest  portion  of  the  assets  or  earning  power
transferred)  which at the time of such transaction would have a market value of
two (2) times the Purchase  Price (such right being called the "Merger  Right").
In the event that a person,  entity or group becomes an Acquiring Person (unless
pursuant  to a tender  offer or  exchange  offer for all  outstanding  shares of
Common Stock at a price and on terms  determined  prior to the date of the first
acceptance  of  payment  for any of such  shares by at least a  majority  of the
members of the Board of  Directors  who are not  officers of the Company and are
not  Acquiring  Persons (or  affiliated or associated  persons  and/or  entities
thereof)  to be  fair  to and in the  best  interests  of the  Company  and  its
shareholders (a "Permitted Offer")), then proper provision shall be made so that
each holder of a Right will,  for a sixty (60) day period  (subject to extension
under certain circumstances) thereafter, have the right to receive upon exercise
that number of shares of Common Stock (or, at the election of the Company, which
election may be obligatory if


                                       3



sufficient authorized shares of Common Stock are not available, a combination of
Common Stock,  property,  other securities  (e.g.,  Preferred Stock) and/or cash
(including by way of a reduction in the Purchase  Price))  having a market value
of two (2) times the Purchase  Price (such right being called the  "Subscription
Right"). The holder of a Right will continue to have the Merger Right whether or
not such holder exercises the Subscription Right. Notwithstanding the foregoing,
upon the  occurrence of any of the events giving rise to the  exercisability  of
the Merger Right or the  Subscription  Right, any Rights that are or were at any
time after the Distribution  Date owned by an Acquiring Person (or affiliated or
associated  persons and/or entities thereof) shall  immediately  become null and
void.

         At any time prior to the  earlier  to occur of (i) a person,  entity or
group  becoming an Acquiring  Person or (ii) the  expiration of the Rights,  the
Company  may redeem the Rights in whole,  but not in part,  at a price of $0.001
per Right (the "Redemption Price"), which redemption shall be effective upon the
action of the Board of  Directors.  Additionally,  the Company may,  following a
person,   entity  or  group  becoming  an  Acquiring  Person,  redeem  the  then
outstanding  Rights in whole,  but not in part, at the  Redemption  Price (i) if
such  redemption  is  incidental  to a  merger  or  other  business  combination
transaction or series of transactions involving the Company but not involving an
Acquiring  Person (or certain related persons and/or entities) or (ii) following
an event  giving rise to, and the  expiration  of the  exercise  period for, the
Subscription  Right if and for as long as the Acquiring  Person  triggering  the
Subscription Right  beneficially owns securities  representing less than fifteen
percent  (15%) of the  outstanding  shares  of  Common  Stock and at the time of
redemption  there  are no other  Acquiring  Persons.  The  redemption  of Rights
described in the preceding sentence shall be effective only as of such time when
the  Subscription  Right  is not  exercisable.  Upon the  effective  date of the
redemption  of the Rights,  the right to exercise the Rights will  terminate and
the only right of the holders of Rights will be to receive the Redemption Price.

         Subject to applicable law, the Board of Directors,  at its option,  may
at any time after a person, group or entity becomes an Acquiring Person (but not
after the acquisition by such Acquiring Person of fifty percent (50%) or more of
the  outstanding  shares  of  Common  Stock),  exchange  all or part of the then
outstanding  and  exercisable  Rights (except for Rights which have become void)
for  shares  of Common  Stock at a rate of one  share of Common  Stock per Right
(subject  to  adjustment)  or,  alternatively,   for  substitute   consideration
consisting  of  cash,  securities  of  the  Company  or  other  assets  (or  any
combination thereof).

         The  Preferred  Stock  purchasable  upon exercise of the Rights will be
nonredeemable  and junior to any other series of preferred stock the Company may
issue  (unless  otherwise  provided in the terms of such  stock).  Each share of
Preferred Stock will have a preferential  quarterly  dividend in an amount equal
to 1,000 times the dividend  declared on each share of Common  Stock,  but in no
event less than $25.00.  In the event of  liquidation,  the holders of shares of
Preferred Stock will receive a preferred  liquidation  payment equal, per share,
to the greater of  $1,000.00 or 1,000 times the payment made per share of Common
Stock. Each share of Preferred Stock will have 1,000 votes, voting together with
the shares of Common Stock. In the event of any merger,  consolidation  or other
transaction  in which  shares  of  Common  Stock are  exchanged,  each  share of
Preferred  Stock will be entitled to receive  1,000 times the amount and type of
consideration  received per share of Common  Stock.  The rights of the Preferred
Stock as to dividends,  liquidation and voting,  and in the event of mergers and
consolidations,  are


                                       4



protected by customary antidilution  provisions.  Fractional shares of Preferred
Stock  will be  issuable;  however,  the  Company  may  elect to (i)  distribute
depositary  receipts  in  lieu  of  such  fractional  shares  and  (ii)  make an
adjustment in cash, in lieu of fractional  shares other than  fractions that are
multiples  of one  one-thousandth  of a share,  based on the market price of the
Preferred Stock prior to the date of exercise.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights should not
be taxable to shareholders or to the Company,  holders of Rights may,  depending
upon the  circumstances,  recognize  taxable  income  in the  event (i) that the
Rights  become  exercisable  for (x) Common Stock or  Preferred  Stock (or other
consideration)  or (y) common stock of an  acquiring  company in the instance of
the Merger Right as set forth above or (ii) of any redemption or exchange of the
Rights as set forth above.

         The Company and the Rights Agent  retain  broad  authority to amend the
Rights Agreement; however, following any Distribution Date any amendment may not
adversely affect the interests of holders of Rights.

         The foregoing  description is qualified in its entirety by reference to
the description of the Rights and their terms set forth in the Rights Agreement,
a copy of which is filed herewith and incorporated  herein by reference.  A copy
of the press release issued on September 24, 2001, announcing the declaration of
the  dividend  of Rights,  also is filed  herewith  and  incorporated  herein by
reference.
