                                                                   July   , 1996
 
Dear Stockholder:
 
   
    A  special meeting of stockholders of  DiviCom Inc. ("DiviCom") will be held
on August 20, 1996 at  9:00 a.m., local time,  at DiviCom's facility located  at
1585 Barber Lane, Milpitas, California 95035.
    
 
   
    At  this special meeting,  you will be  asked to consider  and vote upon the
approval and adoption of  an Agreement and Plan  of Reorganization, dated as  of
May  28, 1996 (the  "Reorganization Agreement"), among  C-Cube Microsystems Inc.
("C-Cube"), its  wholly  owned  subsidiary, C-Cube  Acquisition  Corp.  ("Merger
Sub"),  DiviCom and certain principal stockholders of DiviCom, providing for the
merger of DiviCom with Merger Sub (the "Merger"), as described in the Notice  of
Special  Meeting of  Stockholders following this  letter (the  "Notice") and the
accompanying Prospectus/Proxy Statement. In addition, as described in the Notice
and the Prospectus/Proxy Statement, you will be asked to consider and vote  upon
an  amendment  of  DiviCom's  Certificate  of  Incorporation  (the  "Certificate
Amendment").
    
 
   
    You are also requested to mark the  enclosed proxy card to elect whether  to
receive  solely C-Cube Common Stock  or a combination of  cash and C-Cube Common
Stock in  exchange for  your DiviCom  vested Common  Stock as  a result  of  the
Merger.  In the  event you make  no election,  you will receive  cash and C-Cube
Common Stock in exchange for your  DiviCom vested Common Stock. As described  in
detail  in the Prospectus/Proxy Statement, the  exact amounts of cash and C-Cube
Common Stock received by a stockholder that has not made a "stock only" election
will vary depending  on the  total number of  DiviCom stockholders  that make  a
"stock only" election.
    
 
   
    As  a result of the Merger, all  outstanding vested shares of DiviCom Common
Stock that have  not made a  "stock only" election  and all outstanding  DiviCom
Preferred  Stock will be converted  into the right to  receive an amount of cash
from C-Cube and a fraction  of a share of  C-Cube Common Stock, all  outstanding
unvested  shares of DiviCom Common  Stock or vested shares  as to which a "stock
only" election has  been made  will be  converted into  the right  to receive  a
fraction of a share of C-Cube Common Stock and all outstanding, unvested options
to  acquire  DiviCom Common  Stock will  be  assumed by  C-Cube and  will become
exercisable for shares of  C-Cube Common Stock. Upon  completion of the  Merger,
DiviCom will be a wholly owned subsidiary of C-Cube.
    
 
   
    DiviCom's  Board  of  Directors  has  unanimously  approved  the Certificate
Amendment,  the  Reorganization  Agreement  and  the  transactions  contemplated
thereby.  On the day before signing the Reorganization Agreement, C-Cube's stock
closed at $46.75. Since that date, C-Cube's stock has traded down to $       and
closed  at $      on the day before the printing of this proxy statement. If the
Merger were consummated when the Average  Price of C-Cube's stock was $        ,
the  DiviCom stockholders would receive,  in the aggregate, consideration valued
at $      . Although this is a marked decline from the $195 million value at the
time DiviCom signed the Reorganization Agreement, the Board has determined  that
the  Merger is  in the  best interests  of DiviCom  and its  stockholders. After
careful consideration, the Board of  Directors unanimously recommends a vote  in
favor   of  approval  and   adoption  of  the   Certificate  Amendment  and  the
Reorganization Agreement because of its continued belief in the long-term  value
of  the C-Cube stock and the potential synergies presented by the combination of
the two companies. If the Merger  is approved and consummated, you will  receive
detailed  information  on how  to transmit  your  DiviCom share  certificates to
obtain your cash (if applicable) and shares of C-Cube Common Stock  representing
the Merger consideration. Please note that certain major stockholders of DiviCom
beneficially  owning a total of 96% of the Series A Preferred Stock, 100% of the
Series B Preferred Stock and  47% of Common Stock  of DiviCom outstanding as  of
the  Record Date, have agreed  to vote in favor  of the Reorganization Agreement
and the Merger. As a result of  their agreement, DiviCom believes it is  assured
of  its ability to  obtain the necessary votes  for the Reorganization Agreement
and the Merger. Please  read the Prospectus/Proxy  Statement carefully prior  to
voting.
    
 
    TO ENSURE YOUR REPRESENTATION AT THE MEETING, PLEASE COMPLETE, SIGN AND DATE
THE  ACCOMPANYING PROXY CARD AND RETURN IT IN THE ENCLOSED PREPAID ENVELOPE. You
may revoke your proxy at  any time before it has  been voted, and if you  attend
the  meeting you may  vote in person  even if you  have previously returned your
proxy card. Your prompt cooperation will be greatly appreciated.
 
                                          Sincerely,

    receive  an amount of cash equal to  approximately $2.16 and a fraction of a
    share  of  C-Cube   Common  Stock  equal   to  between  0.063684065827   and

    Common Stock on the  twelve (12) trading days  prior to the DiviCom  Meeting
    and  (iii) all outstanding  unvested shares of DiviCom  Common Stock will be
    converted into the right to receive a  fraction of a share of C-Cube  Common
    Stock equal to between 0.103811571616 and 0.151017023831 per share depending

                     C-CUBE MICROSYSTEMS INC. COMMON STOCK
 
   
    This   Prospectus/Proxy  Statement  constitutes  the  Prospectus  of  C-Cube
Microsystems Inc.,  a Delaware  corporation ("C-Cube"),  with respect  to up  to
2,680,412  shares of its Common Stock, $0.001 par value ("C-Cube Common Stock"),
to be issued in  connection with the proposed  merger (the "Merger") of  DiviCom
Inc.,  a  Delaware corporation  ("DiviCom"),  with and  into  C-Cube Acquisition
Corp., a Delaware corporation and a  wholly owned subsidiary of C-Cube  ("Merger
Sub"),   pursuant  to  the  terms  set  forth  in  the  Agreement  and  Plan  of
Reorganization, dated as of May 28, 1996 (the "Reorganization Agreement"), among
C-Cube, Merger Sub, DiviCom and  certain principal stockholders of DiviCom.  The
Common Stock of DiviCom is herein referred to as "DiviCom Common Stock," and the
Series   A  Preferred  Stock  and  Series  B  Preferred  Stock  of  DiviCom  are
collectively herein referred  to as  "DiviCom Preferred  Stock." DiviCom  Common
Stock  and  DiviCom  Preferred  Stock are  collectively  herein  referred  to as
"DiviCom Capital Stock." As a result of  the Merger, (i) all of the  outstanding
vested  shares of DiviCom Common  Stock that have not  elected to receive "stock
only" consideration will  be converted into  the right to  receive an amount  of
cash  and  a number  of shares  of  C-Cube Common  Stock, (ii)  each outstanding
unvested share of DiviCom Common Stock (I.E., subject to repurchase by  DiviCom)
or  vested Shares  as to  which a "stock  only" election  has been  made will be
converted into a right to receive a  fraction of a share of C-Cube Common  Stock
(subject  to a  right of repurchase  by C-Cube), (iii)  all outstanding unvested
options to acquire shares of DiviCom Common Stock will be assumed by C-Cube  and
thereafter  be  exercisable for  shares  of C-Cube  Common  Stock, and  (iv) all
outstanding vested options  to acquire shares  of DiviCom Common  Stock will  be
canceled.  Assuming (w) that the capitalization of DiviCom at the Effective Time
is in all respects identical to the capitalization of DiviCom at July 31,  1996,
(x)  a closing  date of August  20, 1996, (y)  that no holders  of vested shares
elect to receive "stock  only" consideration and (z)  that the Average Price  is
between  $53.89  and  $25.75 (although  there  can  be no  assurance  as  to the
foregoing), each share of vested DiviCom  Capital Stock that has not elected  to
receive  "stock only"  consideration exchanged in  the Merger  will be converted
into the right to receive approximately $2.16  in cash and the right to  receive
approximately  between  0.063684065827 and  0.07076153211 of  a share  of C-Cube
Common Stock. Each unvested share of DiviCom Common Stock or vested Shares as to
which a "Stock  only" election has  been made  exchanged in the  Merger will  be
converted  into the  right to  receive approximately  between 0.103811571616 and
0.151017023831 of a share  of C-Cube Common Stock.  See "Approval of the  Merger
and  Related  Transactions  --  Manner  and  Basis  of  Converting  Shares."  In
connection with the Merger, 10% of  the shares of C-Cube Common Stock  otherwise
issuable  to  Significant Stockholders  (as defined  herein) of  DiviCom Capital
Stock by virtue of the Merger (the  "Escrow Shares") will be placed into  escrow
and  held as  security for  losses incurred  by C-Cube  in the  event of certain
breaches by  DiviCom  of the  representations  or warranties  contained  in  the
Reorganization  Agreement. See "Approval of  the Merger and Related Transactions
- -- Escrow Fund." Holders of  DiviCom Capital Stock who do  not vote in favor  of
the  Merger  may,  under  certain  circumstances  and  by  following  prescribed
statutory procedures, receive solely  cash for their shares.  See "Terms of  the
Merger -- Appraisal and Dissenters' Rights."
    
 
   
    This  Prospectus/Proxy  Statement also  constitutes  the Proxy  Statement of
DiviCom with respect to the Special Meeting of Stockholders of DiviCom scheduled
to be held at 9:00 a.m. on August  20, 1996 (the "DiviCom Meeting"), and at  any
adjournment  or postponement made  thereof. At the  DiviCom Meeting, the DiviCom
stockholders will  be  asked to  vote  on  (1) approval  of  the  Reorganization
Agreement  and the  Merger and (2)  approval of certain  amendments of DiviCom's
Certificate  of   Incorporation.  This   Prospectus/Proxy  Statement   and   the
accompanying form of proxy are first being mailed to the stockholders of DiviCom

SPECIAL MEETING OF DIVICOM STOCKHOLDERS
 
   
    TIME, DATE, PLACE AND  PURPOSE.  A special  meeting of DiviCom  stockholders
will  be held on August 20, 1996, at 9:00 a.m., local time at DiviCom's facility
located at 1585 Barber Lane,  Milpitas, California (the "DiviCom Meeting").  The
purpose  of the DiviCom Meeting  is (i) to consider and  vote upon a proposal to
approve and adopt the Reorganization Agreement and approve the Merger, and  (ii)
to  consider and vote  upon a proposal approving  an amendment (the "Certificate
Amendment") to DiviCom's  Certificate of  Incorporation (x) to  ensure that  the
Merger  is not treated as  a liquidation for which  holders of DiviCom Preferred
Stock will receive a liquidation preference, and (y) to delete the right of  the
holders  of Series A Preferred Stock to buy certain DiviCom technology for $1.00
upon a dissolution of  DiviCom, and (z) delete  the preemptive rights  provision
contained  in DiviCom's Certificate of Incorporation.  A copy of the Certificate
Amendment is attached as Annex C.
    
 
    RECORD DATE AND VOTE REQUIRED.   Only DiviCom stockholders of record at  the
close  of business on July   ,  1996 (the "DiviCom Record Date") are entitled to
notice of and to vote at the DiviCom Meeting. Under Delaware law and the charter
documents of DiviCom,  approval and  adoption of  the Reorganization  Agreement,
approval  of the  Merger and approval  of the Certificate  Amendment require the
affirmative vote  of (i)  holders of  a majority  of the  outstanding shares  of
DiviCom  Common Stock and  DiviCom Preferred Stock, voting  together as a single
class, and (ii) holders  of a two-thirds majority  of the outstanding shares  of
DiviCom    Preferred   Stock,    voting   separately   as    a   single   class.
 
                                       3

SAGEM S.A., SAGEM International and Tregor  Electronique S.A., each of which  is
organized  under  the laws  of  France, and  Iena  International S.A.,  which is
organized under the laws of Luxembourg (collectively, the "SAGEM Entities"), are
affiliated companies that own collectively as of the DiviCom Record Date 96%  of
the  Series A Preferred Stock, 100% of the Series B Preferred Stock and 18.5% of
the outstanding Common Stock of DiviCom. SAGEM S.A. is the parent or a  majority
shareholder  of each of the other SAGEM Entities. The SAGEM Entities have agreed
to vote their  shares in favor  of approval  of the Merger  and the  Certificate
Amendment,  as has the Chief Executive Officer of DiviCom (who beneficially owns
a total of 1,877,895 shares of  DiviCom Common Stock representing 16.98% of  the
Common  Stock  of DiviCom  as  of May  31, 1996).  In  addition, C-Cube  and its
affiliates hold 3.6% of  the Series A  Preferred Stock and  12.4% of the  Common
Stock  of DiviCom and intend to vote in  favor of the Merger and the Certificate
Amendment. Therefore, assuming that such  stockholders vote as described  above,
the  Merger  and  the Certificate  Amendment  will  be approved  at  the DiviCom
Meeting.
    
 
    As of  the DiviCom  Record Date,  there were     stockholders of  record  of
DiviCom Common Stock and five stockholders of record of DiviCom Preferred Stock.
 
    On  July    , 1996,  a notice meeting  the requirements of  Delaware law was
mailed to all DiviCom stockholders of record as of the DiviCom Record Date.
 
   
THE CERTIFICATE AMENDMENT
    
 
   
    Although three  provisions of  DiviCom's  Certificate of  Incorporation  are
being  amended, they  constitute only one  proposal which is  intended to ensure
that DiviCom's Certificate of Incorporation  not conflict with the actual  terms
of  the proposed Merger. The Certificate Amendment, if approved, would (a) amend
Article V(A)(1)(c) to  provide that  an acquisition shall  not be  treated as  a
liquidation  entitling  the  holders of  the  DiviCom Preferred  Stock  to their
liquidation preference; (b) delete Article IV(A)(4) that currently provides that
upon a dissolution of DiviCom,  the holders of the  Series A Preferred have  the
right  to purchase a  significant portion of DiviCom's  technology for $1.00 and
other DiviCom  assets  at fair  market  value; and  (c)  delete Article  V  that
currently  provides that holders of more than 5% of DiviCom's outstanding shares
have a  preemptive right  to acquire  a pro  rata share  of any  new  securities
offered  by DiviCom. Consistent with the  terms of the Reorganization Agreement,
the Certificate Amendment ensures that the  consideration is paid on a pro  rata
basis  between  the  DiviCom  stockholders,  that  DiviCom  retains  all  of its
technology rights and that  C-Cube receives all  of DiviCom's outstanding  stock
and  technology. As a result of approving the Certificate Amendment, the holders
of the DiviCom Preferred Stock will not receive their liquidation preference  on
the  Merger,  will  not  be  able  to  acquire  the  DiviCom  technology  on its
dissolution and will  no longer have  preemptive rights on  future offerings  of
DiviCom capital stock.
    
 
   
    Pursuant  to the Reorganization Agreement, the Certificate Amendment will be
filed with  the Delaware  Secretary of  State immediately  prior to  filing  the
Agreement  of Merger  effectuating the Merger  and ONLY  if the Merger  is to be
consummated. It  is intended  that if  the  Merger is  approved by  the  DiviCom
stockholders,  the  meeting  will  be adjourned  at  that  point  and reconvened
immediately prior to the closing, at  which time the Certificate Amendment  will
be  voted  on. Given  the Voting  Agreement  signed by  the SAGEM  Entities, the
Certificate Amendment will  be approved.  It is a  condition to  closing of  the
Merger  that the  Certificate Amendment be  approved and effective  prior to the
Effective Time of the Merger.
    
 
THE MERGER
 
   
    TERMS OF THE  MERGER.   As a  result of the  Merger, the  maximum number  of
shares  of C-Cube Common Stock to be issued (including C-Cube Common Stock to be
reserved for  issuance upon  exercise of  any of  DiviCom's options  assumed  by
C-Cube)  in exchange  for the acquisition  by C-Cube of  all outstanding DiviCom
Capital Stock  and  all then-outstanding  unvested  options to  acquire  DiviCom
Capital  Stock will  be 2,680,412,  and the minimum  number of  shares of C-Cube
Common Stock to be issued in the Merger will be 2,412,321. No adjustment will be
made in the number of  shares of C-Cube Common Stock  issued in the Merger as  a
result    of    any   cash    proceeds    received   by    DiviCom    from   the
    
 
                                       4
<PAGE>
   
date of execution  of the Reorganization  Agreement to the  closing date of  the
Merger pursuant to the exercise of options to acquire DiviCom Capital Stock. The
aggregate cash consideration to be paid in such exchange will be $70 million.
    
 
    Subject  to the terms and conditions  of the Reorganization Agreement, as of
the Effective Time, by virtue of the  Merger and without any action on the  part
of Merger Sub, DiviCom or the holder of any shares of DiviCom Capital Stock, the
following will occur:
 
   
    CONVERSION  OF DIVICOM CAPITAL  STOCK.  Each share  of DiviCom Capital Stock
issued and  outstanding immediately  prior to  the Effective  Time that  is  not
subject  to a right of repurchase at  original purchase price (a "vested share")
(other than shares  held by a  holder who  has elected to  receive "stock  only"
consideration  in  the Merger  or who  has  exercised and  perfected dissenters'
rights for  such shares  in accordance  with the  applicable provisions  of  the
Delaware  General Corporation Law (the "DGCL") and who has not withdrawn or lost
such rights  ("Dissenting Shares"))  will be  canceled and  extinguished and  be
converted automatically into the right to receive that fraction of a share of C-
Cube Common Stock equal to the Vested Exchange Ratio (as defined below), and the
Per-Share  Cash  Amount (as  defined below)  upon  surrender of  the certificate
representing such share  of DiviCom Capital  Stock in the  manner provided in  a
letter  of transmittal to be sent to each record holder of DiviCom Capital Stock
prior to the Effective Time (a  "Letter of Transmittal"). Each share of  DiviCom
Capital  Stock issued  and outstanding immediately  prior to  the Effective Time
that is  subject  to  a right  of  repurchase  at original  purchase  price  (an
"unvested  share") or each vested share as  to which a "stock only" election has
been made (other than any Dissenting  Shares) will be canceled and  extinguished
and  be converted  automatically into  the right to  receive that  fraction of a
share of C-Cube Common  Stock equal to the  Unvested Exchange Ratio (as  defined
below),  upon surrender  of the certificate  representing such  share of DiviCom
Capital Stock in  the manner provided  in the Letter  of Transmittal. Rights  to
receive  C-Cube Common Stock in respect of DiviCom Capital Stock pursuant to the
Reorganization Agreement  will  be  subject  to the  escrow  provisions  of  the
Reorganization  Agreement  described under  the section  entitled "Terms  of the
Merger -- Escrow Fund" below.
    
 
   
    Assuming (i) no change in DiviCom capitalization since July 31, 1996, (ii) a
closing date of August 20, 1996, (iii) that no holders of vested DiviCom  Common
Stock  elect to  receive "stock  only" consideration,  and (iv)  that the C-Cube
Average Price is between $53.89 and  $25.75, although there can be no  assurance
as  to these assumptions, all  vested DiviCom Capital Stock  on the Closing Date
that have not elected to  receive "stock only" in  the Merger will be  converted
into  C-Cube Common  Stock at  a rate  that will  be between  0.063684065827 and
0.070761532111 of a  share of  C-Cube stock for  each share  of DiviCom  Capital
Stock  (meaning that  each holder  would receive one  share of  C-Cube stock for
every approximately 15.7 to 14.9 shares  of such vested DiviCom Capital  Stock).
The  actual exchange ratio will depend on the number of vested shares of DiviCom
Capital Stock outstanding immediately prior to the Effective Time, the number of
vested shares that elect to receive  "stock only" consideration and the  Average
Price  of the C-Cube stock.  The lower exchange ratio  will apply if the average
closing price of  the C-Cube Common  Stock for the  12 trading days  immediately
preceding  the date of  the DiviCom Meeting  (the "Average Price")  is $53.89 or
above, with this exchange  ratio being adjusted progressively  up to the  higher
conversion  ratio until the Average Price is  $48.50 and then declining again as
the C-Cube Average Price  declines or as shares  of DiviCom vested Common  Stock
elect  to receive "stock  only" consideration. The  conversion ratio for DiviCom
Common Stock does not increase even if the C-Cube stock price for such period is
lower than $48.50.  On July  22, 1996,  the closing  price of  C-Cube stock  was
$25.75.  Since no adjustment to the aggregate number of shares is required under
the Reorganization Agreement, at  an Average Price of  $25.75, the value of  the
aggregate  value of the  consideration to be  delivered by C-Cube  in the Merger
would be $139 million.
    
 
   
    Each share of DiviCom Capital Stock issued and outstanding immediately prior
to the Effective Time that is not  subject to a right of repurchase at  original
purchase   price  whose  holder   has  not  elected   to  receive  "stock  only"
consideration will also be entitled to  receive a "Per-Share Cash Amount"  equal
to $70 million divided by the number of all such shares electing to receive both
cash  and stock in the merger.  See "Terms of the Merger  -- Manner and Basis of
Converting Shares."
    
 
                                       5
<PAGE>
   
Assuming the  Closing  occurs on  August  20, 1996  (although  there can  be  no
assurance  as to this  assumption) and that 32,370,372  Vested Shares of DiviCom
Capital Stock will be outstanding at the Effective Time by shareholders electing
to receive cash in the Merger, the  Per Share Cash Amount will be  approximately
$2.16.  If  holders  of DiviCom  vested  shares  elect to  receive  "stock only"
consideration, the Per-Share  Cash Amount  received by  those holders  receiving
both  cash and C-Cube stock  will increase and the  exchange ratio will decline,
resulting in such holders receiving  a larger proportion of their  consideration
in  cash and  a smaller  proportion in C-Cube  stock. Assuming  a C-Cube Average
Price of $25.75 (which assumption is  not assured), if only the SAGEM  Entities,
C-Cube  and Mr.  Daines were  to elect  to receive  both stock  and cash  in the
Merger,  it  could  result  in  them  receiving  a  Per-Share  Cash  Amount   of
approximately $2.63 in cash and an exchange ratio of 0.048689419327.
    
 
   
    All  unvested DiviCom  Capital Stock or  vested DiviCom Capital  Stock as to
which a "stock only" election has been made will be converted into C-Cube Common
Stock at a  rate that  will be between  0.103811571616 and  0.151017023831 of  a
share  of C-Cube stock for  each share of DiviCom  stock (the "Unvested Exchange
Ratio"). In other words, each holder of DiviCom Capital Stock would receive  one
share  of C-Cube  stock for  every approximately 9.6  to 6.6  shares of unvested
DiviCom Capital  Stock or  vested  DiviCom Capital  Stock  that has  elected  to
receive  "stock  only"  consideration.  Vesting will  continue  pursuant  to the
original DiviCom vesting schedule and C-Cube will continue to have the right  to
repurchase  unvested shares at  the original purchase  price upon termination of
employment.
    
 
   
    Assuming the Merger  closes on August  20, 1996, that  the Average Price  is
equal  to $25.75 (the closing price of C-Cube  stock on July 22, 1996), and that
no holders of DiviCom Vested Shares elect to receive "stock only" consideration,
although there can be no assurance  as to these assumptions, the Per-Share  Cash
Amount   will  be  approximately  $2.16,  the  Vested  Exchange  Ratio  will  be
0.067037556374 and the Unvested Exchange Ratio will be 0.151017023831.
    
 
    For a more  detailed discussion of  the calculation of  the Vested  Exchange
Ratio,  the Per-Share Cash Amount and the Unvested Exchange Ratio, see "Approval
of the Merger and Related Transaction -- Manner and Basis of Converting  Shares"
below.  The  Vested  Exchange Ratio  and  the  Unvested Exchange  Ratio  will be
adjusted to reflect fully  the effect of any  stock split, reverse split,  stock
dividend,  reorganization, recapitalization or other like change with respect to
C-Cube Common  Stock  or DiviCom  Capital  Stock  occurring after  the  date  of
execution of the Reorganization Agreement and prior to the Effective Time.
 
    No  fraction of a share  of C-Cube Common Stock will  be issued, but in lieu
thereof, each holder of  shares of DiviCom Common  Stock who would otherwise  be
entitled  to a fraction of a share of C-Cube Common Stock (after aggregating all
fractional shares of C-Cube Common Stock to be received by such holder) shall be
entitled to receive from C-Cube an amount of cash (rounded to the nearest  whole
cent) equal to the product of such fraction, multiplied by the Average Price.
 
    CONVERSION  OF OPTION  RIGHTS.  Upon  consummation of the  Merger, each then
outstanding option to purchase DiviCom  Common Stock (each, a "DiviCom  Option")
granted under DiviCom's 1993 Stock Option Plan or its 1996 Stock Option Plan, to
the  extent such DiviCom Option is unvested,  will be assumed by C-Cube and will
automatically be converted  into an  option to purchase  a number  of shares  of
C-Cube  Common Stock determined  by multiplying the number  of shares of DiviCom
Common Stock  subject to  the unvested  portion  of the  DiviCom Option  by  the
Unvested Exchange Ratio, at an exercise price equal to the exercise price of the
DiviCom Option at the time of the Merger divided by the Unvested Exchange Ratio,
rounded  down to the nearest whole cent.  To avoid fractional shares, the number
of shares of C-Cube Common  Stock subject to an  assumed DiviCom Option will  be
rounded  down to  the nearest  whole share. Subject  to the  treatment of vested
DiviCom Options  described  below,  the  other terms  of  the  DiviCom  Options,
including vesting schedules, will remain unchanged.
 
    TERMINATION  OF UNEXERCISED VESTED  OPTIONS.  The  vested portion of DiviCom
Options will not be  assumed by C-Cube, nor  is C-Cube substituting its  options
for such vested DiviCom Options. As a
 
                                       6
<PAGE>
result, each DiviCom Option, to the extent it is vested and not exercised by the
holder  thereof prior  to the  consummation of  the Merger,  shall terminate and
cease to be outstanding as of the consummation of the Merger.
 
   
    EFFECTIVE TIME OF  THE MERGER.   The Merger will  become effective upon  the
filing  of a Certificate of Merger with  the Secretary of State of Delaware (the
"Effective Time"). Assuming that the Reorganization Agreement is not  terminated
and  that all conditions  to the Merger are  met or waived  prior thereto, it is
anticipated that the Effective Time will be on or about August 20, 1996.
    
 
    FORM S-8 REGISTRATION STATEMENT.  C-Cube  has agreed to file a  Registration
Statement  on Form  S-8 with  the Commission,  with respect  to the  issuance of
shares of C-Cube Common Stock upon  exercise of the assumed DiviCom Options,  as
soon  as practicable after the  Merger. See "Approval of  the Merger and Related
Transactions -- Manner and Basis of Converting Shares -- Stock Options."
 
   
    STOCK OWNERSHIP FOLLOWING THE MERGER.  Based upon (i) the capitalization  of
DiviCom  as of the close of business on  July 31, 1996, (ii) the assumption that
no holder of DiviCom Capital Stock elects to receive "stock only"  consideration
or exercises appraisal or dissenters' rights, (iii) a closing date of August 20,
1996,  and (iv) an Average  Price of $25.75 (the  closing price of C-Cube Common
Stock on  July 22,  1996), an  aggregate of  approximately 2,386,443  shares  of
C-Cube  Common Stock will be issued to DiviCom stockholders in the Merger. Based
upon the number of shares  of C-Cube Common Stock  issued and outstanding as  of
May  31, 1996, and after giving effect to the issuance of C-Cube Common Stock as
described in the previous sentence, the former holders of DiviCom Capital  Stock
would  hold, and have  voting power with  respect to, approximately         % of
C-Cube's total  issued and  outstanding shares,  and holders  of former  DiviCom
Options  would hold options  exercisable for approximately         % of C-Cube's
total issued  and  outstanding  shares  (assuming  the  exercise  of  only  such
options). The foregoing numbers of shares and percentages will change subsequent
to  July 31,  1996 and  prior to  the Effective  Time, based  on changes  in the
capitalization of  DiviCom, and  there can  be  no assurance  as to  the  actual
capitalization of C-Cube or DiviCom at the Effective Time.
    
 
   
    ESCROW  FUND.  In connection with the  Merger, at the Effective Time, 10% of
the shares of  C-Cube Common  Stock issuable  by virtue  of the  Merger to  each
holder  of at least 1% of the  outstanding shares of DiviCom capital stock prior
to the Merger on a  fully diluted, as if converted  to Common Stock, basis  with
respect  to all options to acquire such stock (each a "Significant Stockholder")
will be registered in the name  of and deposited with Boston Equiserve  ("Boston
Equiserve"),  as escrow agent  (the "Escrow Agent"),  such deposit to constitute
the escrow fund (the "Escrow Fund"). Such shares (the "Escrow Shares") shall  be
contributed  to the Escrow Fund on behalf of each Significant Stockholder at the
Effective Time in proportion to the aggregate number of shares of C-Cube  Common
Stock  such holder would otherwise  receive by virtue of  the Merger (10% of the
shares otherwise deliverable to each Significant Stockholder). No portion of the
Escrow Fund will be contributed in respect  of any options to acquire shares  of
DiviCom  Capital Stock. The Escrow Shares will be held in escrow as security for
any losses that C-Cube incurs or  reasonably anticipates incurring by reason  of
willful  breaches by DiviCom  of representations or  warranties contained in the
Reorganization Agreement ("Losses"). Significant  Stockholders will have  voting
rights with respect to the Escrow Shares while in escrow. C-Cube may not receive
any  shares from the Escrow Fund unless and until Losses in excess of $2,000,000
have been suffered, in  which case C-Cube  may recover from  the Escrow Fund  an
amount  of Escrow Shares with  a value equal to such  Losses. For the purpose of
compensating C-Cube for  its losses, the  Escrow Shares shall  be valued at  the
average  of the closing prices  of C-Cube Common Stock  for the five consecutive
trading days ending two days prior to  the date such shares are delivered to  C-
Cube  out of  the Escrow  Fund. Subject to  resolution of  unsatisfied claims of
C-Cube, the Escrow Fund shall terminate  270 days following the closing date  of
the Merger. The rights of Significant Stockholders to receive Escrow Shares upon
the  termination of  the Escrow  Fund will  not be  evidenced other  than by the
Reorganization Agreement.  The shares  of  C-Cube Common  Stock subject  to  the
escrow  may be voted by the Significant  Stockholders and, subject to the effect
of  the  escrow  and  other  applicable  transfer  restrictions  (including  the
Affiliate Agreements), may be transferred by the Significant Stockholders.

    BY  APPROVING  THE REORGANIZATION  AGREEMENT,  DIVICOM STOCKHOLDERS  WILL BE
DEEMED TO HAVE CONSENTED TO THE APPOINTMENT OF NOLAN DAINES, PRESIDENT AND CHIEF
EXECUTIVE OFFICER OF DIVICOM, AND CAROLINE DE PUYSEGUR, A REPRESENTATIVE OF  THE
SAGEM  ENTITIES,  TO  ACT  AS  SECURITYHOLDER  AGENTS  ON  BEHALF  OF  DIVICOM'S
SIGNIFICANT STOCKHOLDERS  TO AUTHORIZE  DELIVERY  OF SHARES  HELD IN  ESCROW  TO
C-CUBE IN SATISFACTION OF CLAIMS BROUGHT BY C-CUBE FOR LOSSES, TO OBJECT TO SUCH
DELIVERIES,  AGREE TO, NEGOTIATE AND ENTER INTO SETTLEMENTS AND COMPROMISES WITH
RESPECT TO SUCH CLAIMS,  AND TAKE CERTAIN OTHER  ACTIONS ON BEHALF OF  DIVICOM'S
SIGNIFICANT  STOCKHOLDERS. SEE ARTICLE VII OF THE REORGANIZATION AGREEMENT FOR A
MORE DETAILED EXPLANATION OF THE ESCROW FUND AND RIGHTS WITH RESPECT THERETO.
    
 
   
    MARKET PRICE DATA.  C-Cube Common Stock has been traded on Nasdaq under  the
symbol  "CUBE" since C-Cube's initial public offering  in April 1994. On May 28,
1996, the last trading  day before the announcement  by C-Cube and DiviCom  that
they had signed the Reorganization Agreement, the closing price of C-Cube Common
Stock  as reported  on Nasdaq  was $46.75  per share.  Immediately following the
Merger, C-Cube  Common Stock  will continue  to be  traded on  Nasdaq under  the
symbol  "CUBE." On July  22, 1996, the  closing price of  C-Cube Common Stock as
reported on Nasdaq was  $25.75 per share.  There can be no  assurance as to  the
actual  price of C-Cube Common  Stock prior to, at or  at any time following the
Effective Time. See "Risk Factors" and "C-Cube -- C-Cube Stock Information."
    
 
    No established trading market exists for DiviCom Capital Stock.
 
   
    REASONS FOR THE MERGER.  In the  discussions that led to the signing of  the
Reorganization  Agreement,  C-Cube  and  DiviCom  each  identified  a  number of
potential benefits resulting from  the Merger. C-Cube's  reasons for the  Merger
include the ability to leverage DiviCom's expertise in areas related to C-Cube's
core  competency  in video  compression, the  potential  for increased  sales of
C-Cube decoder products and the  potential to enhance C-Cube's understanding  of
its  customers' systems requirements.  DiviCom's reasons for  the Merger include
leveraging C-Cube's marketing and efforts to promote standards-based  solutions,
increased   access  to  C-Cube's  video  compression  technology  and  increased
stockholder liquidity.  Joint reasons  for  the Merger  include the  ability  to
combine  the  expertise  of the  two  companies  to service  the  emerging video
networking market, to more effectively  enable and cost reduce end-to-end  video
networking  solutions  as well  as the  prospect for  joint development  of next
generation consumer  products  combining  storage-based  and  transmission-based
video  compression technologies.  DiviCom's Board  of Directors  also considered
potential  negative  factors  relating  to  the  Merger,  including   management
disruptions,  potential loss of revenue, the  volatility of C-Cube Common Stock,
and the risks that the desired benefits of the Merger might not be achieved. See
"Approval of the Merger and Related Transactions."
    
 
    RECOMMENDATION OF DIVICOM  BOARD OF DIRECTORS.   The Board  of Directors  of
DiviCom  (the  "DiviCom  Board")  has  unanimously  approved  the Reorganization
Agreement and believes that the Merger is in the best interests of, DiviCom  and
its  stockholders.  See  "Approval of  the  Merger and  Related  Transactions --
Material Contacts." The Board of Directors is comprised of Nolan Daines and four
employees of one of the SAGEM Entities.
 
    CONDUCT OF THE COMBINED COMPANIES FOLLOWING  THE MERGER.  C-Cube intends  to
combine  certain administrative  functions, such as  accounting, human resources
and information systems, following the closing  of the Merger, but to  otherwise
retain  DiviCom as  a separate,  wholly owned  subsidiary. See  "Approval of the
Merger and Related Transactions -- Legal Structure of the Merger."
 
   
    EXCHANGE OF  DIVICOM  STOCK CERTIFICATES.    Prior to  the  Effective  Time,
C-Cube,  acting through  Boston Equiserve as  its exchange  agent (the "Exchange
Agent"), will  deliver  to  each  DiviCom stockholder  of  record  a  letter  of
transmittal  with instructions  to be used  by such  stockholder in surrendering
certificates which, prior to the  Merger, represented shares of DiviCom  Capital
Stock.  CERTIFICATES SHOULD NOT BE SURRENDERED BY THE HOLDERS OF DIVICOM CAPITAL
STOCK UNTIL SUCH  HOLDERS RECEIVE THE  LETTER OF TRANSMITTAL  FROM THE  EXCHANGE
AGENT. At the Effective Time, each then outstanding, unvested option to purchase
DiviCom Common Stock will be assumed by C-Cube without any action on the part of
the holder
    
 
                                       8
<PAGE>
thereof. At the Effective Time, each then outstanding, vested option to purchase
DiviCom  Common  Stock  that  has  not  been  exercised  will  terminate. OPTION
AGREEMENTS NEED NOT  BE SURRENDERED.  See "Approval  of the  Merger and  Related
Transactions -- Manner and Basis of Converting Shares."
 
    CONDITIONS  TO THE  MERGER.   Consummation of the  Merger is  subject to the
satisfaction of  various conditions,  including approval  of the  Merger by  the
requisite vote of the stockholders of DiviCom.
 
   
    Consummation  of  the Merger  is  also subject  to  the satisfaction  of the
following conditions:  the  Registration  Statement filed  with  the  Commission
relating to the issuance of shares of C-Cube Common Stock in connection with the
Merger  shall be effective  and such shares  shall be authorized  for listing on
Nasdaq;  no  injunction,  court  order,  or  other  legal  restraint  preventing
consummation  of the Merger shall  be in effect; and  C-Cube shall be reasonably
satisfied that the Merger will qualify as a "reorganization" within the  meaning
of  the  Internal  Revenue Code.  In  addition,  the obligations  of  DiviCom to
consummate the Merger are subject to the following conditions, unless waived  by
DiviCom:  the representations and warranties of  C-Cube and Merger Sub contained
in the Reorganization Agreement  shall be accurate;  no material adverse  change
will  have occured as to  C-Cube; C-Cube and Merger  Sub shall have performed in
all material respects  the covenants required  by the Reorganization  Agreement;
and  DiviCom shall  have received  a legal  opinion from  counsel to  C-Cube. In
addition, the obligations of C-Cube to consummate the Merger are subject to  the
following   conditions,  unless  waived  by   C-Cube:  the  representations  and
warranties of  DiviCom  contained  in  the  Reorganization  Agreement  shall  be
accurate  except  where  any  breach  or breaches  did  not  have  or  would not
reasonably be expected to have a  material adverse effect on DiviCom or  C-Cube;
DiviCom  shall have performed in all material respects the covenants required by
the Reorganization Agreement;  and C-Cube  shall have received  a legal  opinion
from counsel to DiviCom. See "Approval of the Merger and Related Transactions --
Conditions to the Merger."
    
 
   
    VOTING  AGREEMENT.  The SAGEM Entities  own in aggregate 2,375,493 shares of
DiviCom  Common  Stock  and  20,723,855   shares  of  DiviCom  Preferred   Stock
representing  18.50% and 97.35% of  the votes entitled to  be cast by holders of
shares  of  DiviCom  Common  Stock  and  DiviCom  Preferred  Stock  issued   and
outstanding  as of the DiviCom  Record Date. Each of  these entities, as well as
DiviCom's Chief  Executive  Officer  and  C-Cube,  has  entered  into  a  Voting
Agreement  with C-Cube. Each of the  foregoing individuals and entities has been
identified by DiviCom as an "affiliate" (as that term is defined for purposes of
Rule 145  promulgated under  the Securities  Act) of  DiviCom. Pursuant  to  the
Voting  Agreement, each of the SAGEM Entities and such affiliates have agreed to
vote in favor of approval and adoption of the Reorganization and approval of the
Merger. The vote  of the shares  of DiviCom Common  Stock and DiviCom  Preferred
Stock  subject  to  the  Voting  Agreements  will  be  adequate  to  approve the
Reorganization Agreement and the Merger  by DiviCom stockholders. See  "Approval
of the Merger and Related Transactions -- Voting Agreements."
    
 
    TERMINATION; EXPENSES.  The Reorganization Agreement may be terminated under
certain  circumstances, including,  without limitation,  by C-Cube  if DiviCom's
stockholders have not approved the Merger within thirty days after the effective
date of the  Registration Statement, by  mutual written consent  of C-Cube,  the
SAGEM Entities and DiviCom and by either of C-Cube or DiviCom if the other party
commits  a material  breach or  breaches of  its representations,  warranties or
covenants contained in  the Reorganization  Agreement, or by  C-Cube, the  SAGEM
Entities  or DiviCom if  the Merger is  not consummated on  or before August 31,
1996. Whether or not the Merger  is consummated, all fees and expenses  incurred
in  connection  with  the  Merger  including,  without  limitation,  all  legal,
accounting, financial, advisory, consulting and  all other fees and expenses  of
third  parties  incurred  by a  party  in  connection with  the  negotiation and
effectuation of the terms and conditions of the Reorganization Agreement and the
transactions contemplated thereby,  are the obligation  of the respective  party
incurring such fees and expenses.
 
   
    CERTAIN  INCOME TAX CONSIDERATIONS.  The Merger  is intended to qualify as a
reorganization under Section 368(a) of the Internal Revenue Code of 1986. If the
Merger does so qualify (i) none of
    
 
                                       9
<PAGE>
   
C-Cube, DiviCom or Merger  Sub will recognize  gain or loss as  a result of  the
Merger, and (ii) holders of DiviCom Capital Stock that exchange their shares for
C-Cube  Common Stock and cash will recognize gain, if any, in the Merger but not
in excess of  the amount  of cash  received. However,  it is  possible that  the
Internal  Revenue  Service may  assert that  the  Merger does  not qualify  as a
tax-free reorganization.  See  "Risk  Factors --  Tax  Treatment."  All  DiviCom
stockholders  should consult their own tax advisors. See "The Merger and Related
Transactions -- Certain Federal Income Tax Considerations."
    
 
    ACCOUNTING TREATMENT.   The Merger will  be accounted for  as a purchase  of
DiviCom  by C-Cube for financial reporting purposes in accordance with generally
accepted  accounting  principles.  See  "Approval  of  the  Merger  and  Related
Transactions -- Accounting Treatment."
 
    AFFILIATE AGREEMENTS.  Certain persons identified by DiviCom as "affiliates"
(as  that  term  is defined  for  purposes  of Rule  145  promulgated  under the
Securities Act)  of  DiviCom have  entered  into agreements  restricting  sales,
dispositions  or other transactions reducing their risk of investment in respect
of the shares  of DiviCom Capital  Stock held by  them prior to  the Merger  and
two-thirds  of the shares of C-Cube Common Stock received by them in the Merger,
subject to a  de minimis exception,  so as  to comply with  the requirements  of
applicable  tax laws.  See "Approval of  the Merger and  Related Transactions --
Conditions to the Merger" and "-- Affiliate Agreements."
 
   
    TRANSITION AGREEMENT.   In  connection  with the  Reorganization  Agreement,
SAGEM  S.A., on  behalf of  certain SAGEM  Entities, DiviCom,  C-Cube, and Nolan
Daines, President  and  Chief  Executive  Officer of  DiviCom,  entered  into  a
Transition  Agreement pursuant to  which they agreed  to terminate five existing
agreements (the "Prior  Agreements") between  them (or  some of  them): (i)  the
Joint  Venture  and  Shareholders  Agreement, dated  April  20,  1993;  (ii) the
Business Agreement, dated as  of April 20, 1993;  (iii) the Registration  Rights
and  Buy-Out  Agreement,  dated as  of  April  20, 1993;  (iv)  the  1995 Rap-Up
Agreement, dated January 23, 1996; and (v) the ASIC Purchasing Agreement,  dated
January  23,  1996.  The Prior  Agreements  concerned, among  other  things, the
licensing and  allocation of  marketing  rights between  DiviCom and  the  SAGEM
Entities,  product development  and the supply  of products from  DiviCom to the
SAGEM Entities.
    
 
   
    The Transition  Agreement  assigns  to DiviCom  all  rights  (including  all
intellectual  property rights) that  any party thereto  (other than DiviCom) may
have in any technology related to  any products manufactured, designed, or  sold
by  DiviCom. Under the  Transition Agreement, DiviCom  grants the SAGEM Entities
certain nonexclusive, perpetual  licenses to  some of  its existing  technology,
subject  to royalties payable by the SAGEM  Entities for a three year period. In
addition,  the   Transition  Agreement   grants  the   SAGEM  Entities   certain
distribution  rights to DiviCom products in  Europe. See "Approval of the Merger
and Related Transactions -- Transition Agreement."
    
 
    REGISTRATION RIGHTS AGREEMENT.  C-Cube  and the SAGEM Entities have  entered
into  a Registration  Rights Agreement which  grants the  SAGEM Entities certain
rights to have their shares of C-Cube  Common Stock obtained as a result of  the
Merger  registered under the Securities Act. Pursuant to the Registration Rights
Agreement, the SAGEM  Entities may,  on up to  two occasions  beginning 90  days
after  the effective date of  the Merger and ending  on the third anniversary of
the Closing Date, require C-Cube to register on a Form S-3 not less than 10%  of
the  SAGEM Entities' shares  of C-Cube Common Stock.  Additionally, in the event
C-Cube proposes to  register shares of  C-Cube Common Stock  for the account  of
selling  stockholders, then  C-Cube must  generally include  the SAGEM Entities'
shares of C-Cube Common Stock in such registration on a PRO RATA basis to  those
of the other selling stockholders.
 
    APPRAISAL  AND DISSENTERS' RIGHTS.  Stockholders  of DiviCom who do not vote
in favor  of  the Merger  may,  under  certain circumstances  and  by  following
procedures   prescribed  by  the  Delaware  General  Corporation  Law,  exercise
appraisal rights and receive cash for  their shares of DiviCom Capital Stock.  A
dissenting  stockholder of DiviCom must  follow the appropriate procedures under
Delaware law or suffer the termination  or waiver of such rights. See  "Approval
of the Merger and Related Transactions -- Appraisal and Dissenters' Rights."
 
                                       10
<PAGE>
   
    REGULATORY  MATTERS.   C-Cube and  DiviCom are  aware of  no governmental or
regulatory approvals required  for consummation  of the Merger,  other than  the
filing  of  a Premerger  Notification  and Report  Form  with the  Federal Trade
Commission and the Antitrust Division of  the Department of Justice pursuant  to
the  Hart-Scott-Rodino Antitrust Improvements Act of 1976, as to which notice of
early termination of the waiting period with respect thereto has been  received,
and  compliance with federal securities laws  and the applicable securities laws
of the various states. See "Approval  of the Merger and Related Transactions  --
Governmental and Regulatory Approvals."
    
 
              UNAUDITED SELECTED PRO FORMA COMBINED FINANCIAL DATA
 
   
    The  following table  sets forth the  Unaudited Selected  Pro Forma Combined
Financial Data for the periods and as  of the dates indicated which are  derived
from  the Unaudited Pro Forma Condensed  Combined Financial Statements (the "Pro
Forma Financial  Statements") which  present the  pro forma  condensed  combined
financial  position of C-Cube Microsystems Inc. and  DiviCom Inc. as of June 30,
1996 and the results of operations for the year ended December 31, 1995 and  the
six   month   period  ended   June  30,   1996   contained  elsewhere   in  this
Prospectus/Proxy Statement. The unaudited pro  forma combined balance sheet  has
been  prepared as if  the Merger, which will  be accounted for  as a purchase by
C-Cube,  was  consummated  as  of  June  30,  1996.  The  unaudited  pro   forma
consolidated  combined statements of operations give  effect to the Merger as if
the acquisition were completed at the beginning of the fiscal period presented.
    
 
   
    The Unaudited Selected  Pro Forma  Combined Financial Data  is provided  for
illustrative  purposes only  and is not  necessarily indicative  of the combined
financial position  or  combined results  of  operations that  would  have  been
reported had the Merger occurred on the dates indicated, nor do they represent a
forecast  of the  combined financial position  or results of  operations for any
future period. No pro forma adjustments have been included herein which  reflect
potential  effects of (a) efficiencies which may be obtained by combining C-Cube
and  DiviCom  operations   or  (b)  costs   of  restructuring,  integrating   or
consolidating their operations. In addition, the Pro Forma Combined Statement of
Operations  Data do  not include the  effect of the  $105.4 million nonrecurring
charge  for  in-process   research  and   development  that   has  not   reached
technological  feasibility  and  does  not  have  alternative  future  uses. The
Unaudited  Selected  Pro  Forma  Combined  Financial  Data  should  be  read  in
conjunction with the Unaudited Pro Forma Condensed Combined Financial Statements
and  related notes, and the historical financial statements and related notes of
C-Cube and DiviCom which are included elsewhere herein or incorporated herein by
reference. All amounts are stated in thousands, except for per share amounts.

                                  RISK FACTORS
 
    THIS  PROSPECTUS/PROXY STATEMENT CONTAINS  FORWARD-LOOKING STATEMENTS WITHIN
THE MEANING OF SECTION 27A OF THE SECURITIES ACT OF 1933 AND SECTION 2IE OF  THE
SECURITIES  EXCHANGE ACT  OF 1934. ACTUAL  RESULTS COULD  DIFFER MATERIALLY FROM
THOSE PROJECTED  IN THE  FORWARD-LOOKING  STATEMENTS AS  A  RESULT OF  THE  RISK
FACTORS  SET FORTH BELOW  AND ELSEWHERE IN  THIS PROSPECTUS/PROXY STATEMENT. THE
FOLLOWING FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING THE PROPOSALS  TO
BE VOTED ON AT THE DIVICOM MEETING AND THE ACQUISITION OF THE SECURITIES OFFERED
HEREBY.  FOR PERIODS FOLLOWING THE MERGER, REFERENCES TO THE PRODUCTS, BUSINESS,
RESULTS OF OPERATIONS OR FINANCIAL CONDITION  OF C-CUBE OR, AFTER GIVING  EFFECT
TO THE MERGER, C-CUBE AND DIVICOM (THE "COMBINED COMPANY"), SHOULD BE CONSIDERED
TO  REFER TO C-CUBE AND ITS  SUBSIDIARIES, INCLUDING DIVICOM, UNLESS THE CONTEXT
OTHERWISE REQUIRES.
 
UNCERTAINTIES RELATING TO INTEGRATION OF OPERATIONS
 
    C-Cube and DiviCom have entered  into the Reorganization Agreement with  the
expectation  that the Merger will result  in synergies for the Combined Company.
See "Approval of the  Merger and Related Transactions  -- Joint Reasons for  the
Merger,"  "-- C-Cube's Reasons for the Merger" and "-- DiviCom's Reasons for the
Merger." Achieving the anticipated  benefits of the Merger  will depend in  part
upon  whether the integration of the two companies' businesses is achieved in an
efficient, effective and timely manner, and there can be no assurance that  this
will  occur.  The combination  of the  two companies  will require,  among other
things, successful integration  of DiviCom's digital  video networking  business
with  C-Cube's  current  focus  on digital  video  compression  technologies. To
C-Cube's  knowledge,  there  is  no  fabless  semiconductor  company  that   has
successfully  merged  with and  integrated a  video networking  systems company.
Furthermore,  certain  customers  of  C-Cube  may  perceive  DiviCom  to  be   a
competitor, and the Merger may affect such customers' willingness to do business
with C-Cube. Moreover, certain of DiviCom's suppliers may perceive themselves as
competitors  to C-Cube, and the Merger may affect such suppliers' willingness to
continue doing business on favorable terms or any terms with DiviCom.
 
    There can be no  assurance that integration  will be accomplished  smoothly,
successfully  or in  a timely manner.  The successful expansion  of the Combined
Company's  business  will  require  communication  and  cooperation  in  product
development  and  marketing  among  the  senior  executives  and  key  technical
personnel of C-Cube  and DiviCom.  Given the inherent  difficulties involved  in
completing  a major  business combination, there  can be no  assurance that such
cooperation will occur or that the integration of the respective businesses will
be successful and will not result in  disruptions in one or more sectors of  the
Combined  Company's business.  In addition, there  can be no  assurance that the
Combined Company will retain  its key technical  and management personnel,  that
the market will favorably view C-Cube's proposed entry into the field of digital
video  network systems or that C-Cube will  realize any of the other anticipated
benefits of the Merger. The difficulties of such integration may be increased by
the complexity  of  the  technologies  being integrated  and  the  necessity  of
coordinating  separate  organizations.  The  integration  of  certain operations
following the Merger will require  the dedication of management resources  which
may  temporarily distract attention from the day-to-day business of the Combined
Company. Failure to effectively accomplish the integration of the two companies'
operations  could  have  a  material  adverse  effect  on  C-Cube's  results  of
operations and financial condition.
 
POTENTIAL DILUTIVE EFFECT TO STOCKHOLDERS
 
    Although  C-Cube and  DiviCom believe  that synergies  will result  from the
Merger, there  can be  no assurance  that the  combining of  the two  companies'
businesses,  even if achieved in an efficient, effective and timely manner, will
result in combined  results of  operations and financial  condition superior  in
magnitude  or timeliness in achievement to what would have been achieved by each
company independently. The issuance  of C-Cube Common  Stock in connection  with
the  Merger will have the  effect of reducing C-Cube's  net income per share and
could reduce the market  price of C-Cube Common  Stock unless and until  revenue
growth  or cost  savings and other  business synergies sufficient  to offset the
effect of such issuance  can be achieved.  There can be  no assurance that  such
 
                                       13
<PAGE>
synergies  will  be  achieved.  In  addition, there  can  be  no  assurance that
stockholders of  DiviCom would  not  achieve greater  returns on  investment  if
DiviCom were to seek means to liquidity other than by being acquired.
 
   
VOLATILITY OF C-CUBE STOCK PRICE
    
 
   
    The market price of C-Cube's Common Stock has fluctuated significantly since
the  initial public offering in April 1994. The market price of the Common Stock
could be subject to significant fluctuations in the future based on factors such
as announcements  of  new  products  by C-Cube  or  its  competitors,  quarterly
fluctuations  in C-Cube's  financial results  or other  semiconductor companies'
financial  results,  changes  in  analysts'  estimates  of  C-Cube's   financial
performance,  general conditions in the semiconductor industry and conditions in
the financial markets. In addition, the stock market in general has  experienced
extreme  price  and volume  fluctuations, which  have particularly  affected the
market prices  for many  high technology  companies and  which have  often  been
unrelated   to  the  operating  performance  of  the  specific  companies.  Many
technology companies, including C-Cube, have recently experienced historic highs
in the market  price of their  equity securities. The  market price of  C-Cube's
Common  Stock recently has declined substantially  from such historic highs, and
may continue to experience significant fluctuations in the future.
    
 
   
LIMITED EFFECT ON EXCHANGE RATIO OF C-CUBE COMMON STOCK
    
 
   
    Under the  terms of  the  Reorganization Agreement,  the shares  of  DiviCom
Common Stock issued and outstanding at the Effective Time will be converted into
the right to receive shares of C-Cube Common Stock. In the event of fluctuations
in  the price  of C-Cube  Common Stock, the  adjustments to  the Vested Exchange
Ratio and  the  Unvested  Exchange  Ratio  are  limited  by  the  Reorganization
Agreement.  For example, no adjustment to the  number of shares of C-Cube Common
Stock to be issued in the Merger is required in the event that the Average Price
of  C-Cube  Common  Stock  is  below  $48.50.  Accordingly,  the  value  of  the
consideration  to be  received by stockholders  of DiviCom upon  the Merger will
depend on the market price of the C-Cube Common Stock at the Effective Time.  On
May  28, 1996,  the date  the Reorganization  Agreement was  signed, the closing
price of the C-Cube Common Stock  was $46.75 reflecting a transaction valued  at
$195 million, and on July 22, 1996, the closing price of the C-Cube Common Stock
was  $25.75 reflecting  a transaction  valued at $139  million. There  can be no
assurance that the  market price of  the C-Cube  Common Stock on  and after  the
Effective  Time will not be lower than  such price. See "-- Volatility of C-Cube
Stock Price."
    
 
ATTRACTION AND RETENTION OF KEY EMPLOYEES; DEPENDENCE ON KEY EMPLOYEES
 
    The  ability  of   the  Combined   Company  to   maintain  its   competitive
technological position will depend, in large part, on its ability to attract and
retain  highly qualified  development and managerial  personnel. Competition for
such personnel is intense, and there is a risk of departure of key employees due
to the combination process. As with many private companies that are acquired,  a
number of DiviCom employees who may have contemplated an initial public offering
in  the future will be disappointed  and consider alternative opportunities. The
announcement of the proposed Merger may impede the Combined Company's ability to
attract and retain personnel prior to and after these transactions. The loss  of
a  significant  group  of  key personnel  would  adversely  affect  the Combined
Company's prospects.  C-Cube's  future success  is  heavily dependent  upon  its
ability  to  hire  and  retain  qualified  technical,  marketing  and management
personnel. The  loss of  the services  of key  personnel could  have a  material
adverse  effect on C-Cube's business. C-Cube's success in the future will depend
in part  on the  successful  assimilation of  such  new personnel.  C-Cube  also
obtains  assistance from  customers whose  engineers participate  in development
programs at C-Cube.  The continuing  availability of such  support is  dependent
upon a number of factors, including relationships with customers and the ability
of  such engineers,  many of whom  are foreign residents,  to obtain immigration
visas.  The  competition  for  such  personnel,  particularly  for   engineering
personnel,  is intense  and the  loss of  such personnel  could have  a material
adverse effect on C-Cube. See "--  Dependence on New Product Development;  Rapid
Technological Change" and "C-Cube Business -- Employees."

DEPENDENCE ON EMERGING MARKETS
 
    To  date, C-Cube has derived substantially  all of its product revenues from
sales of  products  for linear  video  playback and  karaoke,  direct  broadcast
satellite applications and computer add-in cards, and from sales of products for
development,  trials and  early deployment  of broadcast  and other applications
that are not  yet commercially available  or are not  yet in volume  production.
C-Cube  expects that  Video CD  and digital  video networking  applications will
continue to account for a significant portion of C-Cube's revenues for the  near
future.  Over the longer  term, C-Cube's ability  to generate increased revenues
will be dependent on the development of new opportunities for compressed digital
video in  the consumer  electronics, communications  and computer  markets.  The
potential  size  of  these new  market  opportunities  and the  timing  of their
development is  uncertain. Substantially  all  of the  growth  in the  sales  of
C-Cube's  decoder products over  the last year has  occurred in the Asia-Pacific
region. There can be no assurance that  such growth will continue or that  other
markets  for C-Cube's  product will  emerge. Further,  C-Cube's success  in such
markets will depend upon whether  system manufacturers select C-Cube's  products
for  incorporation  into  the  system  manufacturers'  products,  and  upon  the
successful introduction of such products. There can be no assurance that  demand
for  Video CD players or  other existing applications will  be sustained or that
new markets  will develop  as expected  by C-Cube,  or at  all, or  that  system
manufacturers  developing  products for  any such  markets will  design C-Cube's
products into  their  system products  and  successfully introduce  such  system
products.  The failure  of existing  and new markets  to develop  as expected by
C-Cube or to  be receptive to  C-Cube's products would  have a material  adverse
effect on C-Cube's business and results of operations.
 
    The  emergence of  markets for  certain digital  video applications  will be
affected by  a variety  of  factors beyond  C-Cube's  or DiviCom's  control.  In
particular,  certain  sectors  of  the communications  market  will  require the
development  and   deployment  of   an  extensive   and  costly   communications
infrastructure.  There can  be no  assurance that  communications providers will
make the necessary  investment in such  infrastructure or that  the creation  of
this  infrastructure will occur in a  timely manner. In addition, the deployment
of such  infrastructure will  be subject  to governmental  regulatory  policies,
taxes  and  tariffs. For  example,  the U.S.  Federal  Communications Commission
currently restricts the number  of new frequencies  available for deployment  of
new digital video broadcast networks, such as wireless cable. In addition, other
countries  have  similar  governmental  restrictions.  The  development  of such
markets could be  delayed or  otherwise adversely affected  by new  governmental
regulations  or changes in  taxes, or tariffs,  or by the  failure of government
agencies to  adopt  changes to  existing  regulations necessary  to  permit  new
technologies  to enter the market.  The emergence of these  and other markets is
also dependent  in  part  upon  third party  content  providers  developing  and
marketing  content  for end-user  products  such as  video  CD and  DVD players,
interactive game consoles,  desktop computers  and settop decoders  in a  format
compatible  with C-Cube's products.  There can be no  assurance that these third
parties will develop and introduce such content in a timely fashion, or at  all,
or  that other  factors beyond  C-Cube's control  will not  adversely affect the
development of the digital  video applications for  which C-Cube's products  are
developed. See "C-Cube Business -- Markets and Applications."
 
FLUCTUATIONS IN OPERATING RESULTS
 
    C-Cube's  quarterly and annual operating results have been and will continue
to be affected by a wide variety  of factors that could have a material  adverse
effect on revenues and profitability during any particular period, including the
level  of  orders  which are  received  and can  be  shipped in  a  quarter, the
rescheduling or cancellation of orders  by its customers, competitive  pressures
on  selling prices, changes in product or customer mix, availability and cost of
foundry capacity and raw materials, fluctuations in yield, loss of any strategic
relationships, C-Cube's ability to introduce new products and technologies on  a
timely   basis,  new  product  introductions  by  C-Cube's  competitors,  market
acceptance of products of both C-Cube and its customers, supply constraints  for
other   components   incorporated   into  its   customers'   products,  currency
fluctuations, the level of expenditures for research and development and  sales,
general   and   administrative  functions   and   the  amount   and   timing  of
 
                                       15
<PAGE>
recognition of development contract revenues. In addition, many of the customers
for the MPEG 1 decoder products (the "CL480 Family") in the Asia-Pacific  region
have  been historically unable to accurately forecast their demand, resulting in
very short notice  of required  delivery by C-Cube,  which may,  in turn,  cause
periods  of product shortfall or surplus.  C-Cube has also recently become aware
that certain of its customers may be  selling some of their excess inventory  of
CL480 devices, which could have a material adverse effect on the market price of
such products. In the future, C-Cube customers may sell their excess inventories
of  other  products comprising  the CL480  Family, which  could have  a material
adverse effect  on  the market  prices  of such  products.  To the  extent  that
customers  cancel orders,  C-Cube's results  of operations  could be  subject to
fluctuations. Furthermore, to the  extent that C-Cube is  unable to fulfill  its
customers' purchase orders on a timely basis, such orders may be canceled due to
changes in demand in the markets for its customers' products.
 
   
    With  respect  to  the DiviCom  digital  video network  systems  business, a
substantial portion of revenues are derived from a limited number of  customers,
resulting  in fluctuations from  period to period that  are outside of DiviCom's
control. Orders from DiviCom's customers can typically be canceled on relatively
short  notice,  making  revenue  prediction  subject  to  uncertainty.  C-Cube's
operating  results are subject to fluctuations in the markets for its customers'
products, particularly the consumer electronics market, which has been extremely
volatile in the past, and the digital broadcast and cable markets, which are  in
an  early stage, creating uncertainty with respect to product volume and timing.
Historically, C-Cube  has  generally recognized  a  substantial portion  of  its
product  revenues in the last month of a given quarter. A significant portion of
C-Cube's expenses are fixed in  the short term, and  the timing of increases  in
expenses  is based in  large part on  C-Cube's and DiviCom's  forecast of future
revenues.  As  a  result,  if  revenues  do  not  meet  C-Cube's  or   DiviCom's
expectations,  the Combined Company may be  unable to quickly adjust expenses to
levels appropriate  to actual  revenues,  which could  have a  material  adverse
effect on the Combined Company's business and results of operations.
    
 
    C-Cube  currently  anticipates that  certain factors  may cause  its product
gross margins to  decline in  the future, including  increased competition,  the
maturation  of C-Cube's products  and the extent to  which revenues derived from
sales of C-Cube's lower margin MPEG 1 and MPEG 2 decoder products increase as  a
percentage   of  C-Cube's  overall  revenues.  See  "--  Changing  Product  Mix;
Increasing Dependence on  Decoder Products"  and "-- Dependence  on New  Product
Development; Rapid Technological Change."
 
    The  growth in revenues and operating income experienced by C-Cube in recent
quarters is not necessarily indicative of  future results. In addition, in  view
of the significant growth in recent years, C-Cube believes that period-to-period
comparisons  of its financial results should not be relied upon as an indication
of future performance. Due  to C-Cube's dependence  on the consumer  electronics
market,  the substantial  seasonality of sales  in such  market could materially
impact C-Cube's revenues  and net  income. In particular,  C-Cube believes  that
there  may be seasonality in the Asia-Pacific  region related to the Chinese New
Year, which  falls  within the  first  calendar quarter,  which  would  indicate
relatively  lower product demand in the second and third quarters. If the future
geographic mix of  C-Cube's sales  shifts towards  the U.S.  and Europe,  C-Cube
would anticipate higher revenues and net income in the third and fourth calendar
quarters,  as system manufacturers in these  areas make purchases in preparation
for the holiday season,  and comparatively less revenues  and net income in  the
first and second calendar quarters. C-Cube's significant growth in prior periods
makes it impossible to assess the effect of any such seasonal trends on C-Cube's
operating  results. There can be no  assurance, however, that C-Cube's operating
results will not exhibit such seasonal characteristics.
 
CHANGING PRODUCT MIX; INCREASING DEPENDENCE ON DECODER PRODUCTS
 
    C-Cube anticipates  that overall  product gross  margins may  decrease as  a
result of a number of factors, including a change in product mix to lower margin
CL480  Family products and anticipated declines in the average selling price for
these products over time. While C-Cube offers a number of products for a variety
of applications, beginning  in the  second quarter  of 1995,  sales of  C-Cube's
 
                                       16
<PAGE>
CL480 Family have represented an increasingly significant percentage of C-Cube's
total  net revenues and  accounted for a  substantial majority of  the growth of
C-Cube's total net revenues. C-Cube expects that revenues from its CL480  Family
will  account for a significant portion of  its product revenues in 1996. C-Cube
derives lower product  gross margins from  sales of the  CL480 Family than  from
sales  of its encoder products.  Therefore, as revenues from  sales of the CL480
Family increase as a percentage of  C-Cube's net revenue, C-Cube may  experience
an  adverse effect on its overall product gross margins. In addition, over time,
C-Cube expects that price competition  will result in declining average  selling
prices  for these products. C-Cube  may not be able  to continue to reduce costs
associated with the CL480  Family sufficiently to offset  the adverse effect  on
overall  product gross margins caused by  the increasing dependence on the CL480
Family. Although C-Cube has implemented several programs to further reduce costs
associated with the CL480 Family, in the event that increases in unit sales  and
other  manufacturing efficiencies of  the CL480 Family  do not offset decreasing
prices in  the future,  C-Cube's business  and results  of operations  would  be
materially  and adversely  affected. Moreover,  as C-Cube  makes changes  to its
CL480 Family in an effort to reduce  costs, its customers must qualify each  new
silicon  and/or microcode revision. Delays  in customers' ability or willingness
to qualify  revisions of  the CL480  products could  result in  higher costs  or
dislocations  in  production and  supply, which  could  have a  material adverse
effect on C-Cube's  operating results. The  timing of volume  shipments and  the
life  cycles of C-Cube's products are difficult  to predict due in large measure
to the emerging nature of the  markets for C-Cube's products, the future  effect
of  product enhancements by  C-Cube and its  competitors and future competition.
Declines in demand for C-Cube's products, particularly the CL480 Family, whether
as a result  of competition,  technological change  or otherwise,  would have  a
material adverse effect on C-Cube's business and results of operations.
 
DEPENDENCE ON NEW PRODUCT DEVELOPMENT; RAPID TECHNOLOGICAL CHANGE
 
    The  markets  for C-Cube's  products are  characterized by  rapidly changing
technology and evolving  industry standards. In  addition, markets for  C-Cube's
products  are characterized  by intense  price competition.  As the  markets for
C-Cube's products  develop and  competition increases,  C-Cube anticipates  that
product  life cycles  will shorten and  average selling prices  will decline. In
particular, average selling prices and product gross margin for each of C-Cube's
products will decline as such products mature and as per order unit volumes  for
such  products increase. C-Cube's operating results will depend to a significant
extent on its ability  to continue to successfully  introduce new products on  a
timely  basis  and to  reduce costs  of existing  products. C-Cube  has recently
announced several new products, including  additional versions of the CL480  and
next  generation MPEG  encoders. There can  be no assurance  that these products
will achieve market acceptance. However, the failure of any of these products to
be successfully introduced and achieve  market acceptance could have a  material
adverse  effect on C-Cube's  business and results of  operations. The success of
new product introductions is dependent on several factors, including proper  new
product  definition,  product cost,  timely completion  and introduction  of new
product designs, quality of new  products, differentiation of new products  from
those  of  C-Cube's  competitors  and  market  acceptance  of  C-Cube's  and its
customers' products.
 
    With respect to the DiviCom digital video network systems business,  DiviCom
will  have to  continue to  stay abreast of  and remain  compatible with various
emerging digital video networks and interoperability standards either adopted in
the industry at large or specified by one or more customers. As a result, C-Cube
and DiviCom believe  that continued  significant expenditures  for research  and
development  will be required in the future.  Because of the complexity of their
respective products, both C-Cube and  DiviCom have experienced delays from  time
to  time in completing development  and introduction of new  products, and, as a
result, have from  time to time  not achieved the  market share anticipated  for
such  products.  There  can  be  no  assurance  that  such  delays  will  not be
encountered in the development and introduction of future products. There can be
no assurance that the  Combined Company will  successfully identify new  product
opportunities  and develop and bring new products  to market in a timely manner,
that products or technologies developed by  others will not render the  Combined
Company's  products  or technologies  obsolete  or noncompetitive,  or  that the
Combined
 
                                       17
<PAGE>
Company's products will be selected for design into the products of its targeted
customers. The failure of any of the Combined Company's new product  development
efforts could have a material adverse effect on C-Cube's business and results of
operations.
 
POTENTIAL FOR PRODUCT RECALL
 
    As  a system designer  and provider, DiviCom may  be responsible for product
defects that have in the past and may in the future not be discovered until such
products have been deployed.  As a result, the  cost of correcting such  defects
could  be considerable, and could have a material adverse effect on the business
and  operating  results  of  the  Combined  Company.  Similarly,   semiconductor
suppliers  such as C-Cube have in the past had to replace substantial numbers of
products which, after  incorporation into  customers' products,  have proven  to
have  reliability  defects. While  C-Cube  has not  experienced  any significant
problems with its products to date, there can be no assurance that such an event
could occur, or  that were it  to occur, it  would not have  a material  adverse
effect on C-Cube's business or results of operations.
 
DEPENDENCE ON WAFER SUPPLIERS AND SUBCONTRACTORS
 
   
    C-Cube   procures  a  majority  of  its  integrated  circuit  products  from
Matsushita Electronics Corporation  ("MEC"), Taiwan Semiconductor  Manufacturing
Corporation  ("TSMC") and Yamaha Corporation.  In addition, DiviCom is dependent
on a sole  supplier of  application specific integrated  circuits ("ASICs")  for
inclusion  in certain of its decoder products. This dependence on a small number
of  foundries  subjects  C-Cube  and   DiviCom  to  risks  associated  with   an
interruption  in supply from these foundries. In connection with the manufacture
of its newer  products, C-Cube  needs to continue  to evaluate  and qualify  new
foundries that employ advanced manufacturing and process technologies, which are
currently  available from a limited number of foundries. For example, certain of
the new  products  that  C-Cube  intends  to  introduce  require  advanced  CMOS
processes  and in the past, C-Cube has experienced increased costs and delays in
connection with the qualification  of new foundries. There  can be no  assurance
that  any  delays,  cost  increases  or  quality  problems  resulting  from  the
qualification of  new foundries  will  not have  a  material adverse  effect  on
C-Cube's business and results of operations.
    
 
    C-Cube's  reliance on subcontractors  to manufacture, assemble  and test its
products involves significant  risks, including: reduced  control over  delivery
schedules,  quality assurance, manufacturing yields and cost; the potential lack
of adequate  capacity; and  potential  misappropriation of  C-Cube  intellectual
property.  C-Cube obtains foundry capacity  through forecasts that are generated
in advance  of expected  delivery  dates and  are  binding on  C-Cube.  C-Cube's
ability  to obtain the foundry capacity necessary  to meet the future demand for
its products is based on its ability to accurately forecast such future  demand.
Due  to cyclical limitations  on foundry capacity  in the semiconductor industry
and lengthy order lead times required  by many wafer suppliers, if C-Cube  fails
to accurately forecast such future demand, C-Cube may be unable to timely obtain
an  adequate supply  of wafers necessary  to manufacture the  number of products
required to satisfy  its actual demand.  There can be  no assurance that  C-Cube
will  accurately forecast future  demand for its  products and obtain sufficient
foundry capacity in the  future. C-Cube's obligation  to make binding  forecasts
far  in advance  of delivery subjects  C-Cube to inventory  risks, including the
risk of  obsolescence and  commitments  for surplus  capacity. With  respect  to
C-Cube's principal foundries, these forecasts are also binding on a foundry upon
acceptance by the foundry, subject to minor adjustments. C-Cube's subcontractors
generally do not have firm supply obligations to C-Cube.
 
    C-Cube  has from  time to time  experienced disruptions  in supply, although
none of those  disruptions has  had a materially  adverse effect  on results  to
date. There can be no assurance that manufacturing or assembly problems will not
occur  in  the future  or that  any such  disruptions will  not have  a material
adverse effect upon  C-Cube's results of  operations. Further, there  can be  no
assurance  that suppliers who have  committed to provide product  will do so, or
that C-Cube  will meet  all conditions  imposed by  such suppliers.  Failure  to
obtain  an adequate  supply of  products on a  timely basis  would delay product
delivery to C-Cube's customers,  which would have a  material adverse effect  on
C-Cube's
 
                                       18
<PAGE>
business and results of operations. In addition, C-Cube's business could also be
materially  and  adversely  affected  if  the  operations  of  any  supplier are
interrupted for a substantial  period of time,  or if C-Cube  is required, as  a
result  of capacity constraints  in the semiconductor  industry or otherwise, to
increase the proportion of wafers or  finished goods purchased from higher  cost
suppliers in order to obtain adequate product volumes.
 
    The  markets  into  which C-Cube  sells  its products  are  characterized by
extreme price competition, and C-Cube expects the selling price of its  products
will  decrease over the life of each product. In order to offset declines in the
selling price  of its  products, C-Cube  will need  to reduce  the cost  of  its
products   by  implementing  cost  reduction   design  changes,  obtaining  cost
reductions as and if volumes  increase, and successfully managing  manufacturing
and  subcontracting  relationships.  Since  C-Cube  does  not  operate  its  own
manufacturing facilities and must make binding commitments to purchase products,
it may not  be able to  reduce its costs  as rapidly as  companies that  operate
their  own  manufacturing  facilities.  The  failure  of  C-Cube  to  design and
introduce lower cost  versions of  C-Cube's products in  a timely  manner or  to
successfully  manage  its  manufacturing  relationships  would  have  a material
adverse effect  on C-Cube's  business  and results  of operations.  See  "C-Cube
Business -- Manufacturing."
 
DEPENDENCE ON CERTAIN CUSTOMERS
 
   
    DiviCom  has derived substantially all of its revenues from contracts with a
limited number of customers. During 1995, Bell Atlantic, EchoStar and certain of
the SAGEM Entities accounted  for over 42%, 25%  and 15% of DiviCom's  revenues,
respectively.  The loss  of any  one of  these customers  would have  a material
adverse effect on DiviCom's business and results of operations.
    
 
POSSIBLE TRANSACTIONS TO OBTAIN ADDITIONAL MANUFACTURING CAPACITY; FUTURE
CAPITAL NEEDS
 
    C-Cube believes that foundry capacity  may become increasingly limited  over
the  next several years, resulting in increased prices, increased lead times and
greater difficulty in obtaining  adequate capacity. Any  increase in the  demand
for  semiconductor  wafers over  currently expected  levels,  or any  failure of
foundry capacity in  the industry  to grow  at anticipated  rates would  magnify
these  shortages. C-Cube's future  operating results will  depend in substantial
part on its ability to increase the  capacity available to it from its  existing
or  new foundries. In order to secure such capacity, C-Cube has entered into and
may in the future enter into various possible transactions, which have or  could
include,   without   limitation,   equity   investments   in,   prepayments  to,
non-refundable deposits with or  loans to foundries  in exchange for  guaranteed
capacity,  "take  or pay"  contracts that  commit  C-Cube to  purchase specified
quantities  of  wafers  over  extended  periods,  or  joint  ventures  or  other
partnership  relationships with foundries. There can be no assurance that C-Cube
will be able to make any further such arrangement in a timely fashion or at all,
that C-Cube will not require additional issuances of equity or debt in order  to
raise  capital  for  such  arrangements  or that  any  such  financing  would be
available to C-Cube on acceptable terms or at all. If C-Cube were not able on  a
timely  basis to obtain additional foundry capacity, its business and results of
operations would be materially and  adversely affected. See "C-Cube Business  --
Manufacturing."
 
COMPETITION
 
    The  markets in which  C-Cube and DiviCom  compete are intensely competitive
and  are  characterized   by  declining   average  selling   prices  and   rapid
technological  change.  C-Cube  and  DiviCom  compete  with  major  domestic and
international companies, most of which have substantially greater financial  and
other  resources than  C-Cube with  which to  pursue engineering, manufacturing,
sales, marketing and distribution of their products. Some of these companies own
proprietary video compression technology competitive with C-Cube's and DiviCom's
standards-based  systems.  In   the  consumer   electronics  market,   principal
competitors  include Philips,  SGS-Thomson, Oak  Technology and  ESS Technology,
Inc., as  well  as  several  large,  integrated  Japanese  consumer  electronics
companies,   such  as  Sony,  Toshiba,  NEC,  and  MEI,  which  have  their  own
semiconductor design and manufacturing  capacity. In the communications  market,
C-Cube's principal competitors include SGS-Thomson, LSI Logic, Texas Instruments
and   IBM  Microelectronics.   In  its  compression   and  networking  business,
 
                                       19
<PAGE>
DiviCom competes with vertically  integrated system suppliers including  General
Instrument,  Scientific Atlanta, Philips and Thomson  Broadcast, as well as more
specialized suppliers including the  DMV division of News  Corp., Nuko, and  the
TV/COM division of Hyundai. In the computer market, principal C-Cube competitors
include  the  increasingly  powerful CPUs  that  are now  available  from, among
others, Intel and Motorola, as well  as specialized companies such as Zoran  and
8x8,  and  graphics  chip  manufacturers such  as  S3  Incorporated  and Trident
Microsystems, Inc. In DiviCom's settop box business, DiviCom competes  primarily
with  General Instruments, Scientific  Atlanta, as well  as consumer electronics
companies (which  may  choose to  license  DiviCom technology  or  compete  with
DiviCom  and its licensees) such as Thomson Consumer Electronics, Philips, Sony,
Matsushita, Mitsubishi, Zenith, Hyundai and Samsung.
 
    Recently,  competition   among   suppliers   of  encoder   chips   for   the
communications  market  has intensified  significantly. IBM  and LSI  Logic have
recently announced the  commercial availability  of their own  MPEG 2  encoders.
C-Cube  expects that other companies, such  as SGS-Thomson and Mitsubishi, among
others, will introduce competing encoder  products in the near future.  Although
the timing of the availability of such encoders is uncertain, their availability
would  likely have  an adverse impact  on C-Cube's encoder  product revenues and
margins. C-Cube  may also  face increased  competition in  the future  from  new
entrants  into its markets. In particular,  as the markets for C-Cube's products
develop, competition from  large semiconductor companies,  such as  SGS-Thomson,
and   from   fabless   semiconductor  companies   may   increase  significantly.
Furthermore, as  part  of C-Cube's  foundry  relationships, C-Cube  has  granted
certain  foundries  the rights  to develop  and manufacture  derivative products
based on its technology, subject to royalty obligations and certain limitations,
which  may  facilitate  direct  competition  from  these  larger   semiconductor
companies.  The ability  of C-Cube  and DiviCom  to compete  successfully in the
rapidly evolving  markets  for  high performance  video  compression  technology
depends  on factors both within and outside of its control, including success in
designing and subcontracting the manufacture of new products that implement  new
technologies,  adequate  sources  of  raw materials,  protection  of  C-Cube and
DiviCom products by effective utilization of intellectual property laws, product
quality, reliability, price and the efficiency of production, the pace at  which
customers  incorporate  C-Cube's  integrated  circuits  into  their  products or
incorporate DiviCom's products or technologies, success of competitors' products
and general  economic conditions.  There  can be  no  assurance that  C-Cube  or
DiviCom will be able to compete successfully in the future. See "C-Cube Business
- -- Competition."
 
    A  variety  of  other  approaches to  digital  video  compression  have been
introduced, including wavelets, fractals, proprietary compression algorithms and
software-only solutions, and other companies are designing products around these
or  alternative  approaches.  In  addition,  manufacturers  of  general  purpose
microprocessors  are  positioning  their  products  as  offering  digital  video
compression capability, and there can be no assurance that system  manufacturers
will  not use such  processors for video compression  applications. In the event
that any of these other approaches, individually or collectively, are adopted in
the emerging video compression market  on a widespread basis, C-Cube's  business
and  results  of  operations would  be  materially and  adversely  affected. See
"C-Cube Business -- Research and Development" and "-- Competition."
 
INTELLECTUAL PROPERTY PROTECTION AND DISPUTES
 
    C-Cube and DiviCom attempt to protect their technology through a combination
of patents,  copyright and  trade secret  laws, confidentiality  procedures  and
licensing arrangements. To that end, C-Cube has obtained and DiviCom has applied
for  certain patents and intend to continue  to seek patents on their respective
technology when appropriate. There can be  no assurance that patents will  issue
from  any of these pending applications or that any claims allowed from existing
or pending patents will be sufficiently  broad to protect C-Cube's or  DiviCom's
technology.  While  C-Cube  and  DiviCom  intend  to  protect  their  respective
intellectual property  rights vigorously,  there can  be no  assurance that  any
patents  held  by  or  issued  to C-Cube  or  DiviCom  will  not  be challenged,
invalidated or circumvented, or that the rights granted thereunder will  provide
competitive  advantages to C-Cube.  Moreover, while C-Cube  holds or has applied
for patents relating to the design of its products,
 
                                       20
<PAGE>
   
C-Cube's products are based in part on  standards, including MPEG 1, MPEG 2  and
JPEG, and C-Cube does not hold patents or other intellectual property rights for
such standards. C-Cube and DiviCom believe that there are outstanding patents in
this  area which may need to be licensed by C-Cube or DiviCom. The semiconductor
industry is  characterized by  frequent litigation  regarding patent  and  other
intellectual  property rights. While there  is currently no pending intellectual
property litigation against C-Cube or  DiviCom, C-Cube and DiviCom receive  from
time  to time notices of potential infringement  of third party rights and there
can be no assurance that third parties will not assert claims against C-Cube and
DiviCom with respect  to existing or  future products or  that licenses will  be
available  on  reasonable terms,  or  at all,  with  respect to  any third-party
technology including  third-party technology  which  is or  may be  embodied  in
standards.  In  the  event  of  litigation  to  determine  the  validity  of any
third-party claims,  such  litigation could  result  in significant  expense  to
C-Cube  and divert the efforts of C-Cube's or DiviCom's technical and management
personnel, whether or not such litigation  is determined in favor of C-Cube.  In
the  event of an adverse result in any such litigation, C-Cube could be required
to pay  substantial amounts  in  damages and  to  cease selling  the  infringing
product  unless and until C-Cube is able to develop non-infringing technology or
to obtain licenses to  the technology which was  the subject of the  litigation.
There can be no assurance that C-Cube would be successful in such development or
that such licenses would be available, and any such development or license could
require  expenditure of  substantial time  and other  resources. The protections
afforded C-Cube's  and  DiviCom's  respective intellectual  property  rights  by
foreign  legal  systems  may  vary  significantly,  based  on  multilateral  and
bilateral agreements, as well as  the legislative developments in each  country.
Neither C-Cube nor DiviCom can assure that the measures utilized by each of them
to  protect their intellectual property rights  from piracy in foreign countries
will be effective. See "C-Cube Business -- Intellectual Property and Licenses."
    
 
MANAGEMENT OF GROWTH
 
    C-Cube has recently experienced  a period of  significant growth, which  has
placed,  and could continue  to place, a significant  strain on C-Cube's limited
personnel and other resources.  C-Cube's ability to  manage any further  growth,
should  it  occur, would  require  significant expansion  of  its manufacturing,
research and development and marketing and sales capabilities and personnel.  In
particular,  C-Cube is in the process  of expanding its research and development
and sales and marketing organizations to increase coverage of the United  States
and  the Asia-Pacific region. There can be no assurance that C-Cube will be able
to find qualified  personnel to fill  such sales and  marketing positions or  be
able  to  successfully manage  a broader  sales  and marketing  organization. In
addition, the  sale  and  distribution  of products  to  numerous  large  system
manufacturers  in diverse markets and the requirements of such manufacturers for
design support would  also place  substantial demands on  C-Cube's research  and
development  and sales functions. C-Cube's ability to manage any further growth,
should it occur, would depend upon its ability to manage and potentially  expand
its  foundry relationships.  The failure  of C-Cube's  management to effectively
expand or manage  these functions  consistent with  any growth  which may  occur
could  have  a  material adverse  effect  on  C-Cube's business  and  results of
operations.
 
RISKS ASSOCIATED WITH INTERNATIONAL BUSINESS ACTIVITIES
 
   
    International revenues have accounted for a significant portion of  C-Cube's
net  revenues in the past, and  C-Cube believes that international revenues will
continue to account for a significant portion of net revenues. C-Cube's  success
will depend in part upon its ability to manage international marketing and sales
operations  and  manufacturing relationships.  In  addition, C-Cube  purchases a
substantial portion of  its assembly services  from foreign suppliers.  C-Cube's
international  manufacturing  and  sales  are  subject  to  changes  in  foreign
political and economic conditions and to other risks including currency exchange
rate fluctuations or export/import controls and changes in tax laws, tariffs and
freight rates. For example,  China and Taiwan  comprise substantial markets  for
consumer  electronics products utilizing C-Cube's CL480 Family, such as Video CD
players. As  a  consequence,  any  political or  economic  instability  in  such
countries  could  significantly  reduce  demand  for  products  from  certain of
C-Cube's  major  customers.  C-Cube  has  recently  secured  additional  foundry
capacity in
    
 
                                       21
<PAGE>
   
the  Republic of China (Taiwan) from  TSMC. Consequently, C-Cube will subject to
the risk of political  instability in Taiwan, including  but not limited to  the
potential  for conflict  between Taiwan and  the People's Republic  of China. In
addition, C-Cube sells certain of its products in international markets and buys
certain products from its  foundries in currencies other  than the U.S.  dollar,
and  C-Cube does not  currently hedge its exposure  to foreign currency exchange
rate fluctuations. As a result, currency exchange rate fluctuations could have a
material adverse effect  on C-Cube's  business and results  of operations.  With
respect  to international sales that are  denominated in U.S. dollars, increases
in the value of the U.S. dollar relative to foreign currencies can increase  the
effective  price  of  and  reduce  demand  for  C-Cube's  products  relative  to
competitive products  priced  in  the  local currency.  The  United  States  has
considered  trade  sanctions against  Japan and  is considering  trade sanctions
against China relating to trade and human rights issues. If trade sanctions were
imposed, Japan  or China  could enact  trade sanctions  in response.  Because  a
number  of C-Cube's current and prospective  customers and suppliers are located
in Japan and China, trade sanctions,  if imposed, could have a material  adverse
effect  on C-Cube's business and results of operations. Similarly, protectionist
trade legislation in either the United States or foreign countries could have  a
material  adverse  effect on  C-Cube's  ability to  manufacture  or to  sell its
products in foreign markets.
    
 
   
TAX TREATMENT
    
 
   
    It is possible that the Internal Revenue Service may assert that the  Merger
does  not qualify as a tax-free reorganization  because of a failure to meet the
"continuity of  interest" requirement  applicable  to reorganizations.  The  law
relating to the continuity of interest requirement and the effect of post-Merger
sales  of C-Cube  Common Stock,  if any, by  former DiviCom  stockholders is not
clear. A successful  Internal Revenue  Service challenge  to the  reorganization
status of the Merger would generally result in a DiviCom stockholder recognizing
gain  equal to  the difference  between the  stockholder's basis  in his  or her
DiviCom Capital Stock and the fair-market value, as of the Effective Time of the
Merger, of the C-Cube Common Stock  and cash received in exchange therefor.  See
"Terms of the Merger -- Certain Federal Income Tax Considerations."
    
 
LIMITED HISTORY OF C-CUBE PROFITABILITY
 
   
    C-Cube  was organized in 1988 and  first achieved profitability in the third
quarter of 1993. At June  30, 1996, C-Cube had  retained earnings of only  $29.8
million  and,  on a  pro forma  basis, the  Combined Company  would have  had an
accumulated deficit of $76.8 million at June 30, 1996. See "Unaudited Pro  Forma
Condensed  Combined Financial Statements." There can be no assurance that C-Cube
or the Combined Company will be able to sustain profitability in the future.
    
 
ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS
 
    Certain provisions of C-Cube's Certificate of Incorporation and Bylaws could
discourage potential acquisition proposals and  could delay or prevent a  change
in  control of  C-Cube. Such provisions  could diminish the  opportunities for a
stockholder to participate in tender offers, including tender offers at a  price
above  the then current  market value of  the Common Stock.  Such provisions may
also inhibit increases in the market price of the Common Stock that could result
from takeover attempts. In addition, the  Board of Directors of C-Cube,  without
further  stockholder approval, may issue Preferred Stock, with such terms as the
Board of Directors  may determine,  that could have  the effect  of delaying  or
preventing  a change in control of C-Cube. The issuance of Preferred Stock could
also adversely affect the voting power of the holders of Common Stock, including
the loss of voting control to others. C-Cube also has a classified board and  is
afforded the protections of Section 203 of the Delaware General Corporation Law,
either  of which could delay  or prevent a change in  control of C-Cube or could
impede a merger, consolidation, takeover or other business combination involving
C-Cube or  discourage  a  potential  acquiror from  making  a  tender  offer  or
otherwise attempting to obtain control of C-Cube.

proxy, will constitute a quorum for the transaction of business.
 
VOTING OF PROXIES
 
   
    This Prospectus/Proxy Statement  is being  furnished to  holders of  DiviCom
Capital Stock in connection with solicitation of proxies by and on behalf of the
Board of Directors of DiviCom for use at the DiviCom Meeting. In addition to the
consideration  of the  Reorganization Agreement and  the Merger,  the only other
matter to  be  brought before  the  DiviCom Meeting  will  be the  amendment  to
DiviCom's  Certificate of  Incorporation to  (i) ensure  that the  Merger is not
treated as a liquidation for which  the holders of DiviCom Preferred Stock  will
receive  a  liquidation preference,  (ii)  delete the  right  of the  holders of
DiviCom Series A Preferred Stock to buy certain DiviCom technology for $1.00  on
a  DiviCom dissolution and other DiviCom assets  at fair market value, and (iii)
delete the preemptive  rights provision  contained in  DiviCom's Certificate  of
Incorporation   (such  amendments   collectively  constitute   the  "Certificate
Amendment"). A copy  of the Certificate  Amendment is attached  as Annex C.  All
shares of DiviCom Capital Stock that are entitled to vote and are represented at
the  DiviCom Meeting either  in person or by  properly executed proxies received
prior to or at the DiviCom Meeting and not duly and timely revoked may be  voted
at the DiviCom Meeting by the holders thereof who are present at such meeting or
in  accordance with the instructions indicated on such proxies, respectively. If
no such instructions are indicated, such proxies will be voted for the  approval
and  adoption of  the Reorganization Agreement,  the Merger  and the Certificate
Amendment. As to any business other than that described herein that may properly
come before  the DiviCom  Meeting, it  is  intended that  proxies, in  the  form
enclosed,  will be voted in  respect thereof in accordance  with the judgment of
the persons voting such proxies. Any  proxy given pursuant to this  solicitation
may  be revoked by the person giving it  at any time before it is voted. Proxies
may be revoked  by (i) delivering  to the  Secretary of DiviCom  (by any  means,
including  facsimile) a written notice bearing a date later than the date of the
proxy, stating that the proxy is revoked, (ii) a subsequent proxy that is signed
by the person  who signed  the earlier  proxy and  is presented  at the  DiviCom
Meeting  or  (iii)  attendance  at  the DiviCom  Meeting  and  voting  in person
(although attendance  at the  DiviCom  Meeting will  not,  by itself,  revoke  a
proxy).
    
 
                                       23
<PAGE>
VOTE REQUIRED
 
   
    Approval  and adoption of  the Reorganization Agreement,  the Merger and the
Certificate Amendment requires  the affirmative  vote of  (i) the  holders of  a
majority  of the outstanding shares of  DiviCom Common Stock and Preferred Stock
entitled to vote thereon, voting together as a single class (with each share  of
DiviCom  Common Stock  entitled to  cast one  vote per  share and  each share of
Preferred Stock entitled  to a  number of  votes equal  to the  number of  whole
shares  of DiviCom Common Stock into which such share of DiviCom Preferred Stock
could be converted on the record date for the vote), and (ii) two-thirds of  the
outstanding  DiviCom Preferred Stock entitled to vote thereon, voting separately
as a single class. Each  record holder of DiviCom  Capital Stock on the  DiviCom
Record  Date is  entitled to  cast votes, exercisable  in person  or by properly
executed  proxy,  on  each  matter  properly  submitted  for  the  vote  of  the
stockholders  of DiviCom at  the DiviCom Meeting. The  SAGEM Entities, which own
collectively as of the DiviCom Record Date  96% of the Series A Preferred  Stock
of  DiviCom, 100% of  the Series B  Preferred Stock of DiviCom  and     % of the
outstanding Common Stock of DiviCom, have  agreed to vote their shares in  favor
of  approval of the Merger, as has DiviCom's Chief Executive Officer and C-Cube,
who own collectively as of the DiviCom  Record Date an additional 29.38% of  the
Common  Stock of  DiviCom. Therefore,  assuming that  such stockholders  vote as
agreed, the Merger will be approved at the DiviCom Meeting.
    
 
ABSTENTIONS
 
    Abstentions will be  included in determining  the presence of  a quorum  and
will  have  the  same  effect  as votes  against  the  proposal  to  approve the
Reorganization Agreement and the Merger at the DiviCom Meeting.
 
EXPENSES; SOLICITATION OF PROXIES
 
    The cost  of the  solicitation  of DiviCom  stockholders  will be  borne  by
DiviCom.  Proxies may  be solicited by  certain DiviCom  directors, officers and
employees personally or by telephone, telegram or other means of  communication.
Such persons will not receive additional compensation, but may be reimbursed for
reasonable out-of-pocket expenses incurred in connection with such solicitation.
 
APPRAISAL AND DISSENTERS' RIGHTS
 
   
    Stockholders  of DiviCom who do  not vote in favor  of the Merger may, under
certain circumstances and by following  procedures prescribed by Section 262  of
the DGCL, exercise appraisal rights and receive cash for their shares of DiviCom
Capital  Stock. A dissenting stockholder of  DiviCom must follow the appropriate
procedures under  Delaware law  or  suffer the  termination  or waiver  of  such
rights. See "Terms of the Merger -- Appraisal and Dissenters' Rights."
    
 
   
CERTIFICATE AMENDMENT
    
 
   
    Although  three  provisions of  DiviCom's  Certificate of  Incorporation are
being amended, they  constitute only one  proposal which is  intended to  ensure
that  DiviCom's Certificate of Incorporation not  conflict with the actual terms
of the proposed Merger. The Certificate Amendment, if approved, would (a)  amend
Article  V(A)(1)(c) to  provide that  an acquisition shall  not be  treated as a
liquidation entitling  the  holders of  the  DiviCom Preferred  Stock  to  their
liquidation preference; (b) delete Article IV(A)(4) that currently provides that
upon  a dissolution of DiviCom,  the holders of the  Series A Preferred have the
right to purchase a  significant portion of DiviCom's  technology for $1.00  and
other  DiviCom  assets at  fair  market value;  and  (c) delete  Article  V that
currently provides that holders of more than 5% of DiviCom's outstanding  shares
have  a  preemptive right  to acquire  a pro  rata share  of any  new securities
offered by DiviCom. Consistent with  the terms of the Reorganization  Agreement,
the  Certificate Amendment ensures that the consideration  is paid on a pro rata
basis between  the  DiviCom  stockholders,  that  DiviCom  retains  all  of  its
technology  rights and that  C-Cube receives all  of DiviCom's outstanding stock
and technology. As a result of approving the Certificate Amendment, the  holders
of  the DiviCom Preferred Stock will not receive their liquidation preference on
the Merger,  will  not  be  able  to  acquire  the  DiviCom  technology  on  its
dissolution,  and will no  longer have preemptive rights  on future offerings of
DiviCom capital stock.
    
 
                                       24
<PAGE>
   
    Pursuant to the Reorganization Agreement, the Certificate Amendment will  be
filed  with  the Delaware  Secretary of  State immediately  prior to  filing the
Agreement of Merger  effectuating the Merger  and ONLY  if the Merger  is to  be
consummated.  It  is intended  that if  the  Merger is  approved by  the DiviCom
stockholders, the  meeting  will  be  adjourned at  that  point  and  reconvened
immediately  prior to the closing, at  which time the Certificate Amendment will
be voted  on. Given  the Voting  Agreement  signed by  the SAGEM  Entities,  the
Certificate  Amendment will  be approved.  It is a  condition to  closing of the
Merger that the  Certificate Amendment be  approved and effective  prior to  the
Effective Time of the Merger.

                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS
 
JOINT REASONS FOR THE MERGER
 
    C-Cube  and DiviCom  have identified several  mutual benefits  of the Merger
that they believe will contribute to the success of the Combined Company.  These
potential benefits include:
 
   
    -COMPATIBLE  STRATEGIES.    DiviCom  and  C-Cube  have  compatible  business
     strategies based upon open standards, interoperability and diverse business
     relationships with partners and customers.  The adoption of open  standards
     is  critical  to allow  companies  such as  C-Cube  and DiviCom  to compete
     against entrenched  suppliers which  often  support their  own  proprietary
     standards  (e.g. MPEG 2  as an open standard  vs. Digicypher, a proprietary
     technology of  General Instruments).  The Merger  will allow  the  Combined
     Company  to more  effectively promote  standards-based solutions, including
     MPEG 2, ATM, DVB, etc., in their lines of business.
    
 
    -COMBINED EXPERTISE IN EMERGING DIGITAL VIDEO NETWORKING MARKET.  C-Cube has
     expertise in the video compression market, the core enabling technology for
     digital video networking.  DiviCom has expertise  in networking,  including
     video compression. The Combined Company will be able to deliver new product
     solutions  to a  wider range  of customers than  either company  on a stand
     alone basis.
 
    -ENABLE END-TO-END DIGITAL VIDEO  NETWORKING SOLUTIONS.  Delivering  digital
     video  networking systems solutions involves integrating numerous elements,
     including video and audio compression, transport multiplexing,  conditional
     access,  subscriber management,  transmission, diagnostics  and interactive
     services, among others.  The Combined  Company will be  better situated  to
     develop  and  deliver advanced  solutions  that incorporate  each company's
     expertise in these elements.
 
    -REDUCE COST  OF SETTOP  BOX BY  PRODUCT INTEGRATION.   Settop  boxes  today
     contain  separate subsystems for digital  video and audio decoding, network
     interface, system control and utilities such as electronic program  guides.
     By  understanding  all  these  disparate  elements,  the  Combined  Company
     believes  it  can  identify  areas  for  potential  integration  and   cost
     reduction,  potentially offering solutions which are superior to those that
     are based on discrete subsystems.
 
    -DEVELOP  NEXT  GENERATION  SYSTEMS  THAT  MERGE  STORAGE  AND  TRANSMISSION
     TECHNOLOGIES.   Today there are different systems sold to consumers for the
     consumption of  networked  digital  video  (E.G.,  settop  boxes)  and  the
     playback  of  storage  based media  (E.G.,  Video CD  players).  C-Cube and
     DiviCom believe that the combined expertise of C-Cube and DiviCom,  through
     their  understanding  of  storage-based  and  network-based  digital  video
     architectures respectively, could lead to  the development of a wide  range
     of platforms that include both technologies, helping to create new types of
     consumer products.
 
    -DIVERSIFICATION  OF C-CUBE PRODUCT LINE.  DiviCom currently markets certain
     semiconductor  ASIC  products  under  license.  In  the  past,  C-Cube  has
     licensed,  manufactured and sold one of these ASICs. As a Combined Company,
     there will  be  increased opportunity  to  jointly define  and  sell  these
     products,   diversifying   C-Cube's  product   portfolio   and  potentially
     generating more  revenue than  if these  products were  only sold  under  a
     royalty-bearing license.
 
    -BROADEN MARKETING AND SALES SUPPORT CHANNELS.  DiviCom customers are highly
     concentrated  in the  U.S. and Europe,  while the majority  of C-Cube sales
     currently come from the Asia-Pacific Region. The Combined Company will have
     the opportunity to realize efficiencies in managing customer sales activity
     and technical support worldwide.

<PAGE>
C-CUBE'S REASONS FOR THE MERGER
 
    In addition  to  the  anticipated joint  benefits  described  above,  C-Cube
believes  that the acquisition of DiviCom is a significant strategic opportunity
for C-Cube.  C-Cube believes  that the  acquisition of  DiviCom will  provide  a
variety of advantages to C-Cube, including the following:
 
    -TECHNOLOGY  LEVERAGE.  C-Cube will be  able to leverage DiviCom's expertise
     in transport multiplexing,  conditional access  encryption and  statistical
     multiplexing  and  other technologies  outside  its core  video compression
     business to enhance future product offerings.
 
    -POTENTIAL FOR  INCREASED SALES  OF C-CUBE  DECODER PRODUCTS.   Through  the
     anticipated  benefits  accruing  from  DiviCom's  technological  expertise,
     C-Cube believes that certain  of its decoder  products may be  increasingly
     attractive to its customers.
 
    -ENHANCE  UNDERSTANDING OF CUSTOMERS' SYSTEMS REQUIREMENTS.  C-Cube believes
     that, as issues  arise in the  development of end-to-end  solutions in  the
     video  networking  applications market,  it  will be  better  positioned to
     identify improvements in its products in  order to make them more  suitable
     to its video networking customers as a result of the Merger.
 
    -MEET    COMPETITIVE    CHALLENGE   FROM    OTHER    VERTICALLY   INTEGRATED
     SUPPLIERS.  Certain  of C-Cube's and  DiviCom's competitors are  integrated
     systems  and semiconductor suppliers.  The addition of  DiviCom will enable
     C-Cube to more effectively  compete with such companies  than if it were  a
     stand alone semiconductor supplier.
 
DIVICOM'S REASONS FOR THE MERGER
 
    The  Board of Directors of  DiviCom believes that the  Merger is in the best
interests of  DiviCom and  its stockholders  and therefore  recommends that  the
stockholders  of DiviCom  vote FOR approval  and adoption  of the Reorganization
Agreement and  approval of  the Merger.  Four of  the members  of the  Board  of
Directors  are  employees of  one  of the  SAGEM  Entities. In  addition  to the
benefits described above, the DiviCom Board considered the following factors  in
arriving at this decision:
 
   
    -STOCKHOLDER VALUE.  The Merger will enable DiviCom stockholders to exchange
     their  privately held  DiviCom Capital Stock  for cash  and publicly traded
     C-Cube Common  Stock and  enable  holders of  unvested DiviCom  options  to
     receive  unvested  options to  purchase C-Cube  Common  Stock that  will be
     registered with the Commission and thus publicly tradable once the  options
     are  exercised. In addition, certain other rights and privileges of DiviCom
     stockholders will also change as a result of the Merger. Upon completion of
     the Merger,  each  former DiviCom  stockholder  will have  a  substantially
     smaller  percentage  ownership of  C-Cube  than such  stockholder's current
     percentage ownership of DiviCom.  Accordingly, former DiviCom  stockholders
     will  have a significantly  smaller voting influence  on a percentage basis
     over the  affairs of  C-Cube than  currently enjoyed  over the  affairs  of
     DiviCom.
    
 
    -IMPROVED  ABILITY TO COMPETE.  DiviCom's competitors include companies that
     are  larger  than   DiviCom  and  have   longer  operating  histories   and
     significantly  greater  capital and  resources.  DiviCom believes  that its
     ability to compete for certain large sales against such companies has, from
     time to time, been adversely  affected by customer preferences for  larger,
     more  established suppliers. DiviCom  further believes that  the Merger has
     the potential to improve DiviCom's competitive position by making available
     the greater resources of the Combined  Company (such as access to  capital,
     marketing and research and development resources).
 
    -DISTRIBUTION  SYNERGIES.  The  Merger would provide  DiviCom with access to
     C-Cube  merchant  semiconductor  sales  channels  that  are  not  currently
     available  to DiviCom,  allowing DiviCom  to obtain  the higher  margins on
     sales  made  through  this  channel.  Moreover,  DiviCom  believes  it  can
     capitalize  upon  operating  and distribution  efficiencies  made available
     after the  Merger as  a  result of  more  uniform and  global  distribution
     capabilities provided by C-Cube.

    - ELIMINATION  OF PREFERENTIAL  RIGHTS.  The  SAGEM Entities  have agreed to
      waive all  preferential rights  to the  Merger consideration  in favor  of
      equal treatment with holders of DiviCom Common Stock by signing the Voting
      Agreement  in which they agreed to vote for the Certificate Amendment. The
      Certificate Amendment enables  a more favorable  allocation of the  Merger
      consideration to the DiviCom stockholders (other than the SAGEM Entities).
    
 
   
    - ELIMINATION  OF RESTRICTIONS ON  DOING BUSINESS.   The SAGEM Entities also
      have  agreed  to  eliminate  certain  business  restrictions  and   reduce
      obligations relating to the development and transfer of DiviCom technology
      as  embodied  in the  Transition Agreement.  This agreement  should enable
      DiviCom to compete more effectively in the future on a global basis.
    
 
    - CONSISTENT CORPORATE CULTURE.   C-Cube's corporate  culture, policies  and
      practices   in  retaining  employees  and   its  business  operations  are
      consistent with the expectations of DiviCom employees.
 
DIVICOM BOARD RECOMMENDATION OF APPROVAL OF THE MERGER
 
   
    In addition  to  the factors  listed  above, DiviCom's  Board  of  Directors
considered the following factors. DiviCom's Board of Directors determined not to
pursue  a stand-alone public offering as an alternative due to the greater risk,
delay and expense such a transaction entails, and to the lack of certainty  that
such  a transaction could  be completed or that  the price at  which it could be
completed would be  attractive. DiviCom's  management determined  in early  1996
that  DiviCom could benefit  from a business combination  with a strong industry
partner that would bring to the Combined Company increased financial  resources,
complementary   product  offerings,   enhanced  market   presence  and  expanded
distribution capabilities, as  well as  a release from  existing technology  and
market  arrangements with  the SAGEM  Entities. The  DiviCom Board  of Directors
believes that as larger, more vertically integrated companies increasingly enter
the digital video technology market, a  company such as that resulting from  the
Merger  has  substantially greater  chances to  compete  and grow.  In addition,
notwithstanding DiviCom's extensive contacts with leading electronics  companies
other  than C-Cube, no  comparable offers to the  transaction proposed by C-Cube
were received by the Board of Directors.
    
 
   
    In the course of its deliberations, the DiviCom Board of Directors  reviewed
a number of additional factors relevant to the Merger with DiviCom's management.
In  particular, the DiviCom Board  considered: (i) information concerning C-Cube
and DiviCom's  businesses, historical  financial  performance, product  mix  and
customer  mix; (ii) an evaluation  of the prospects of  DiviCom on a stand-alone
basis based  on internally  developed  projections of  its business;  (iii)  the
compatibility  of the management and businesses  of DiviCom and C-Cube; and (iv)
oral reports from  management and  legal advisors on  the results  of their  due
diligence  investigation  of  C-Cube. After  carefully  considering  DiviCom and
C-Cube's respective  businesses, historical  financial performance,  operations,
products  and prospects, C-Cube's financial resources, its complementary product
offerings and  strategy,  its substantial  market  presence and  its  sales  and
distribution  capabilities, as well  as the other factors  referred to above and
the potentially  negative  factors  referred  to below,  the  Board  of  DiviCom
concluded  that the relative  valuations of DiviCom and  C-Cube reflected in the
Vested Exchange Ratio, Unvested  Exchange Ratio and Per  Share Cash Amount  were
appropriate  and that the Merger would  have the substantial advantages referred
to above for the Combined Company.
    
 
   
    The Board of Directors of DiviCom also considered the following  potentially
negative factors in its deliberations concerning the Merger: (i) the possibility
of  management disruption associated with the  Merger and the risk that, despite
the efforts of the  Combined Company, the  Combined Company may  not be able  to
retain  key technical and  management personnel of DiviCom  and C-Cube; (ii) the
potential loss of revenues to the Combined  Company as a result of confusion  in
the  marketplace and the possible exploitation  of such confusion by competitors
of the Combined Company;  (iii) the substantial  accounting charges and  related
cash  requirements  expected to  be incurred  by C-Cube  in connection  with the
Merger and  the risk  that  the trading  price of  C-Cube  Common Stock  may  be
    
 
                                       28
<PAGE>
   
adversely  affected by these or  other factors; (iv) the  risk that the benefits
sought to be achieved by the Merger will not be achieved; (v) the volatility  of
C-Cube's stock price; and (vi) other risks described above under "Risk Factors."
    
 
   
    The  DiviCom  Board of  Directors met  on  July 25,  1996 to  reevaluate its
recommendation of  approval  of the  Merger  given the  substantial  decline  in
C-Cube's  stock price since the Reorganization  Agreement had been executed. The
Board noted that  C-Cube's financial  results for  its second  quarter had  been
strong  and  consistent with  analysts' published  reports and  concluded, after
discussion,  that  the  consideration   offered  by  C-Cube  still   represented
substantial  value to the DiviCom stockholders.  The Board also reconsidered the
factors discussed above,  given DiviCom's current  capital requirements and  the
current  unsettled security  markets, and  concluded that  the Merger represents
DiviCom's best alternative at this time.
    
 
   
    In view  of  the  wide  variety of  factors,  both  positive  and  negative,
considered  by  the  DiviCom Board  of  Directors,  the Board  did  not  find it
practical to, and did not, quantify or otherwise assign relative weights to  the
specific  factors considered. After taking into consideration all of the factors
set forth above, the  Board of Directors of  DiviCom determined that the  Merger
was  in the  best interests  of DiviCom  and its  stockholders and  that DiviCom
should proceed with the Merger at this time.
    
 
    THE BOARD OF DIRECTORS OF  DIVICOM BELIEVES THAT THE  MERGER IS IN THE  BEST
INTERESTS OF DIVICOM AND ITS STOCKHOLDERS AND THEREFORE UNANIMOUSLY RECOMMENDS A
VOTE FOR APPROVAL OF THE REORGANIZATION AGREEMENT AND THE MERGER.
 
MATERIAL CONTACTS
 
   
    In  December 1992, Dr. Alexandre Balkanski, then the Vice President of Sales
of C-Cube, asked Mr. Nolan Daines,  who would later become the President,  Chief
Executive Officer, Chief Financial Officer and a director of DiviCom, to discuss
the  subject of incorporation of DiviCom. Dr. Balkanski introduced Mr. Daines to
the SAGEM  Entities  and helped  in  the  initial organization  of  DiviCom.  At
inception, C-Cube was granted approximately 7% of the Common Stock of DiviCom in
exchange for certain technology and Dr. Balkanski was named to the DiviCom Board
of  Directors. In August 1994, C-Cube  provided approximately $220,000 in equity
investment for approximately 550,000 shares of DiviCom Preferred Stock.
    
 
    On November  14, 1994,  DiviCom  and C-Cube  negotiated and  signed  license
rights  for C-Cube to purchase, manufacture and resell a chip subsequently known
as the CL9110 Transport Demultiplexer.
 
    Dr.  Balkanski  served  on   the  Board  of  Directors   of  DiviCom  as   a
representative  of C-Cube's  interests in DiviCom  until July 21,  1995. At that
time, Dr. Balkanski submitted his resignation from DiviCom's Board of  Directors
due  to his appointment as President and Chief Executive Officer of C-Cube as of
July 1, 1995.
 
   
    Informal discussion between Dr. Balkanski and Mr. Daines regarding a  closer
relationship  between C-Cube and DiviCom,  including potential synergies between
the video  network  systems business  and  the video  compression  semiconductor
business, occurred intermittently after that date. These discussions became more
focused upon a potential business combination in early 1996.
    
 
    On  February 16, 1996, Mr. Daines contacted  Gabriel Matter, who serves as a
director of DiviCom as a representative of one of the SAGEM Entities'  interests
in DiviCom. Mr. Daines explained that C-Cube might be interested in entering the
digital  video systems business by way of  a strategic combination and that, due
to the close relations  existing between C-Cube and  DiviCom, Dr. Balkanski  had
asked  him  whether  the SAGEM  Entities  would  be interested  in  receiving an
acquisition proposal. Mr. Daines  added that Dr. Balkanski  wished to meet  with
Michel Toussan, Vice President and Managing Director of the Electronics Division
of  SAGEM S.A.  and Chairman  of the  Board of  DiviCom, in  order to informally
discuss C-Cube's interest in a possible merger with DiviCom.
 
                                       29
<PAGE>
   
    From February 16, 1996 through March 31, 1996, C-Cube conducted  preliminary
due  diligence on DiviCom, and certain  members of management of C-Cube, DiviCom
and SAGEM met to discuss a  possible merger. Involved in those discussions  were
Mr.  Daines,  Dr. Lookabaugh,  Nai-Ting  Hsu and  Rick  Prime from  DiviCom, Dr.
Balkanski, Mr. Burke, Dr. LeGall, Mr. Daly  and Mr. Foreman from C-Cube and  Mr.
Matter  and Mr. Toussan of SAGEM. Matters concerning system versus semiconductor
business models,  complementary  product  strategies  as  well  as  early  views
regarding  structure  and  organizational  issues  were  all  discussed. General
business issues concerning customers,  key contracts and development  activities
were also reviewed.
    
 
   
    On  February 27, 1996, Dr. Balkanski met  with Mr. Michael Wishart of Lehman
Brothers to  outline  the possibility  of  a transaction  and  requested  Lehman
Brothers  to prepare analyses to establish possible metrics for the valuation of
DiviCom, with  a  focus on  finding  comparable valuations  of  publicly  traded
companies.
    
 
   
    On  March 12, 1996,  Dr. Balkanski met  in Paris with  Mr. Toussan, at which
meeting a potential business combination, and  the possible valuation of such  a
transaction based on initial data supplied by Lehman Brothers, was discussed.
    
 
   
    On  April  1,  1996,  DiviCom  and  C-Cube  entered  into  a confidentiality
agreement. Shortly thereafter  the companies  exchanged preliminary  information
and   conducted  preliminary  due  diligence   investigations  of  each  other's
businesses. This  due  diligence  featured presentations  given  by  the  senior
management  of DiviCom to Dr. Balkanski, outlining details of operations of each
of the major  functional units  of DiviCom  as well  as a  discussion of  future
product development plans.
    
 
   
    A  meeting was  held in  Paris, France,  on April  22, 1996.  Present at the
meeting were Dr.  Balkanski, Messrs.  Daines and Toussan  and Mario  Colaiacovo,
Vice  President and Chief Financial Officer  of SAGEM S.A. C-Cube then submitted
to the persons present a  merger proposal. On the afternoon  of the same day,  a
summary  of terms, after having  been negotiated and revised,  was signed by Dr.
Balkanski on  behalf of  C-Cube, Mr.  Daines  on behalf  of DiviCom  and  Pierre
Faurre, Chairman of the Board and Chief Executive Officer of SAGEM S.A.
    
 
   
    On  the afternoon of May 7, 1996, and during the day May 8, 1996, Mr. Daines
of DiviCom, Dr. Balkanski, Mr. Burke and  Mr. Foreman of C-Cube and Mr.  Matter,
Mr.  Toussan  and Mr.  Galliard  of SAGEM  met  at C-Cube's  offices  to discuss
definitive documentation for the Merger.  At those meetings, the parties  agreed
to  the limited "collar" provision and  negotiated other provisions, such as the
"no shop"  clause and  the various  closing conditions  and requirements  for  a
tax-free transaction.
    
 
   
    From  May  21, 1996  through May  23,  1996 Mr.  Daines, Dr.  Balkanski, Mr.
Toussan and Mr.  Gaillard met in  New York, New  York, with Mr.  Matter and  Mr.
Fallevoz  participating  from  time to  time  by telephone  conference  call, to
negotiate  the  remaining  unresolved  issues  concerning  formulation  of   the
allocation   of  the   Merger  consideration,   the  escrow   arrangements,  the
representations and warranties in the Reorganization Agreement, the drafting and
discussion of  the Transition  Agreement and  finalizing the  other  transaction
documents.
    
 
    On  May 23, 1996, the Board of Directors of DiviCom met with DiviCom's legal
counsel, considered  the  terms  of the  Reorganization  Agreement  and  related
agreements  as then  negotiated, as  well as  the results  of the  due diligence
review of C-Cube, and unanimously approved the Reorganization Agreement.
 
    On May 24, 1996  the Board of  Directors of C-Cube  met with C-Cube's  legal
counsel,  considered  the  terms  of the  Reorganization  Agreement  and related
agreements as  then negotiated,  the  results of  the  due diligence  review  of
DiviCom, and unanimously approved the Reorganization Agreement.
 
    On  May 28, 1996, officers of DiviCom  and C-Cube and representatives of the
SAGEM Entities executed  the Reorganization Agreement,  and the proposed  Merger
was publicly announced.

                              TERMS OF THE MERGER
 
    THE   FOLLOWING  DISCUSSION  SUMMARIZES  THE  PROPOSED  MERGER  AND  RELATED
TRANSACTIONS. THE  FOLLOWING  IS  NOT,  HOWEVER, A  COMPLETE  STATEMENT  OF  ALL
PROVISIONS  OF  THE REORGANIZATION  AGREEMENT  AND RELATED  AGREEMENTS. DETAILED
TERMS OF  AND CONDITIONS  TO THE  MERGER AND  CERTAIN RELATED  TRANSACTIONS  ARE
CONTAINED IN THE REORGANIZATION AGREEMENT, A CONFORMED COPY OF WHICH IS ATTACHED
TO  THIS  PROSPECTUS/ PROXY  STATEMENT AS  APPENDIX A.  STATEMENTS MADE  IN THIS
PROSPECTUS/PROXY STATEMENT WITH  RESPECT TO  THE TERMS  OF THE  MERGER AND  SUCH
RELATED  TRANSACTIONS ARE QUALIFIED IN  THEIR RESPECTIVE ENTIRETIES BY REFERENCE
TO THE MORE DETAILED INFORMATION SET FORTH IN THE REORGANIZATION AGREEMENT.
 
EFFECTIVE TIME
 
   
    The Reorganization Agreement provides that the Merger will become  effective
upon  the filing  of a Certificate  of Merger by  the Secretary of  State of the
State of Delaware  in accordance  with the DGCL  (the "Effective  Time"). It  is
anticipated  that if all conditions of the Merger have been fulfilled or waived,
the Effective Time will occur on or about August 20, 1996, or on a date as  soon
as practicable thereafter.
    
 
   
OVERVIEW OF MERGER CONSIDERATION AND EXCHANGE RATIOS
    
 
   
    Upon consummation of the Merger, C-Cube will pay the DiviCom stockholders up
to  $70  million  in cash  and  2,680,412  shares of  C-Cube  Common  Stock. The
allocation of consideration  between cash  and C-Cube  stock was  the result  of
negotiations between the parties. During the negotiations, the parties discussed
paying  either (i) all stock or (ii)  stock plus cash consideration for DiviCom.
The majority DiviCom stockholder preferred to have as large a cash component  as
possible. C-Cube was not willing to pay more than $70 million in cash and wanted
the  remainder of the consideration to be paid in C-Cube stock in order that the
Merger be characterized as "reorganization" within the meaning of Section 368 of
the Code. Similarly,  DiviCom wanted  its U.S. DiviCom  stockholders to  receive
C-Cube stock on a tax-deferred basis.
    
 
   
    Pursuant  to  the Reorganization  Agreement, the  amount of  consideration a
DiviCom stockholder receives is determined  pursuant to the exchange ratios  set
forth  below. The parties agreed that there would be two exchange ratios: one of
which converted  DiviCom  stock  solely  into C-Cube  stock,  and  another  that
converted  DiviCom  stock  into  C-Cube  stock and  a  certain  amount  of cash.
Permitting two forms of  payment was considered  desirable for several  reasons.
First,  DiviCom wanted to allow  the holders of vested  Common Stock to elect to
receive only stock consideration, rather than  partly stock and partly cash.  By
electing to receive "stock only" consideration, a DiviCom stockholder can obtain
tax  deferred treatment on all of the  consideration paid by C-Cube. Second, for
certain accounting  reasons, C-Cube  wanted to  require the  holders of  DiviCom
unvested Common Stock to receive only stock consideration. Although this results
in  two different exchange ratios  depending on the form  of consideration to be
received, the  formulas for  determining  each exchange  ratio are  designed  to
ensure  that whether a DiviCom stockholder is  to receive all stock or stock and
cash, each DiviCom stockholder will receive an equivalent value of consideration
based on the Average Price of the C-Cube stock.
    
 
   
    In addition to  the consideration being  paid in the  Merger by C-Cube,  the
holders  of the DiviCom  Preferred Stock have  agreed to give  up certain rights
that they  hold under  DiviCom's  Certificate of  Incorporation, and  the  SAGEM
Entities  have agreed to  give up certain  contractual rights that  they have to
DiviCom's technology. See "DiviCom Meeting" -- "The Certificate Amendment" for a
discussion of  amendments to  DiviCom's Certificate  of Incorporation  to  allow
equal  division of the  merger consideration and  "Terms of the  Merger" -- "The
Transition  Agreement"  for   a  discussion  of   the  elimination  of   certain
restrictions  on DiviCom's ability to  do business, intellectual property rights
assigned to  DiviCom and  marketing  and product  rights  granted to  the  SAGEM
Entities in connection with the Merger.

<PAGE>
MANNER AND BASIS OF CONVERTING SHARES
 
   
    As  a result of  the Merger, the  maximum number of  shares of C-Cube Common
Stock to be issued  (including C-Cube Common Stock  to be reserved for  issuance
upon  exercise of any of DiviCom's options  to be assumed by C-Cube) in exchange
for the acquisition by C-Cube of  all outstanding DiviCom Capital Stock and  all
then-outstanding  unvested  options to  acquire  DiviCom Capital  Stock  will be
2,680,412. No adjustment will be made in  the number of shares of C-Cube  Common
Stock  issued in the Merger as a result of any cash proceeds received by DiviCom
from the date of execution of  the Reorganization Agreement to the closing  date
of  the Merger  pursuant to  the exercise of  options to  acquire DiviCom Common
Stock.
    
 
    Subject to the terms and conditions  of the Reorganization Agreement, as  of
the  Effective Time, by virtue of the Merger  and without any action on the part
of Merger Sub, DiviCom or the holder of any shares of DiviCom Capital Stock, the
following will occur:
 
   
        CONVERSION OF  DIVICOM CAPITAL  STOCK.   Each share  of DiviCom  Capital
    Stock issued and outstanding immediately prior to the Effective Time that is
    not  subject to  a right of  repurchase at original  purchase price ("Vested
    Shares") (other than any Dissenting Shares) that has not elected to  receive
    "stock  only"  consideration  will  be  canceled  and  extinguished  and  be
    converted automatically into the right to  receive that fraction of a  share
    of  C-Cube  Common Stock  equal  to the  Vested  Exchange Ratio  (as defined
    below), and cash  in the  amount of the  Per-Share Cash  Amount (as  defined
    below)  upon surrender of the certificate representing such share of DiviCom
    Capital Stock in the manner provided in  a letter of transmittal to be  sent
    to  each record holder of DiviCom Capital  Stock prior to the Effective Time
    (a "Letter of Transmittal"). Each share of DiviCom Capital Stock issued  and
    outstanding  immediately prior  to the Effective  Time that is  subject to a
    right of repurchase  at original purchase  price ("Unvested Shares")  (other
    than any Dissenting Shares) and each Vested Share as to which a "stock only"
    election  has been made  will be canceled and  extinguished and be converted
    automatically into the right to receive  that fraction of a share of  C-Cube
    Common  Stock equal to the Unvested  Exchange Ratio (as defined below), upon
    surrender of  the certificate  representing such  share of  DiviCom  Capital
    Stock  in  the manner  provided  in the  Letter  of Transmittal.  Since cash
    received in the Merger is taxable upon receipt, holders of Vested Shares are
    being given the opportunity to elect to receive the Unvested Exchange  Ratio
    (consisting  of "stock only"  consideration, instead of  the Vested Exchange
    Ratio (consisting of stock and cash consideration). Rights to receive C-Cube
    Common  Stock  in  respect  of   DiviCom  Capital  Stock  pursuant  to   the
    Reorganization  Agreement will  be subject to  the escrow  provisions of the
    Reorganization Agreement described under the section entitled "Terms of  the
    Merger -- Escrow Fund" below.
    
 
   
        "Aggregate Cash Amount" means $70,000,000.
    
 
   
        "Aggregate  Share  Number" means  the quotient  (rounded to  the nearest
    share) obtained  by dividing  (i) $130,000,000  by (ii)  the lesser  of  (x)
    $53.89  (which would result in  a quotient of 2,412,321  shares) and (y) the
    average of the closing  prices of a  share of C-Cube's  Common Stock on  the
    Nasdaq  National  Market,  or  the  national  securities  exchange  on which
    C-Cube's Common  Stock is  then traded,  for the  twelve (12)  trading  days
    immediately  preceding the  date of  the Company's  stockholder meeting (the
    "Company  Meeting")  at  which  the   Merger  and  the  other   transactions
    contemplated  by  this Agreement  are submitted  for approval  (the "Average
    Price"); provided, however, that if the quotient obtained thereby is greater
    than  2,680,412,   the   quotient  shall   be   deemed  to   be   2,680,412.
    Notwithstanding anything herein to the contrary, additional shares of C-Cube
    Common  Stock shall  be issuable in  connection with payments  to holders of
    unvested DiviCom Options and unvested  DiviCom Common Stock pursuant to  the
    Unvested Exchange Ratio.
    
 
   
        "Per-Share  Cash  Amount" means  the quotient  obtained by  dividing the
    Aggregate Cash Amount  by the  number of  vested shares  of DiviCom  Capital
    Stock  outstanding immediately prior to the  Effective Time that are held by
    "Non-Electing Stockholders" (as defined below). To
    
 
                                       32
<PAGE>
   
    determine cash paid to a particular  stockholder, the Per Share Cash  Amount
    shall  be multiplied by the  number of Vested Shares  held by a Non-Electing
    Stockholder and then rounded to the nearest whole cent.
    
 
   
        "Price Per DiviCom Share"  means the quotient  obtained by dividing  (a)
    the  sum  of (i)  the  Aggregate Cash  Amount and  (ii)  the product  of the
    Aggregate Share Number multiplied by the Average Price, by (b) $35,750,000.
    
 
   
        "Stock Portion of Price"  means the amount  obtained by subtracting  the
    Per Share Cash Amount from the Price Per DiviCom Share.
    
 
   
        "Vested  Exchange  Ratio" means  the quotient  obtained by  dividing the
    Stock Portion of Price by the Average Price.
    
 
   
        "Unvested Exchange Ratio"  means the quotient  obtained by dividing  the
    Price Per DiviCom Share by the Average Price.
    
 
   
        "Non-Electing  Stockholders"  are  those  DiviCom  stockholders  holding
    vested shares of DiviCom stock who did  not submit to DiviCom, on or  before
    the DiviCom Meeting, their written election to receive the Unvested Exchange
    Ratio with respect to those Vested Shares.
    
 
        No  fraction of a  share of C-Cube  Common Stock will  be issued, but in
    lieu thereof,  each holder  of shares  of DiviCom  Capital Stock  who  would
    otherwise be entitled to a fraction of a share of C-Cube Common Stock (after
    aggregating  all fractional shares of C-Cube  Common Stock to be received by
    such holder) shall  be entitled  to receive from  C-Cube an  amount of  cash
    (rounded  to  the  nearest whole  cent)  equal  to the  product  obtained by
    multiplying such fraction by the Average Price.
 
        CONVERSION OF OPTION RIGHTS.  Upon consummation of the Merger, each then
    outstanding option  to  purchase  DiviCom Common  Stock  (each,  a  "DiviCom
    Option")  granted under DiviCom's  1993 Stock Option Plan  or its 1996 Stock
    Option Plan, to the extent such DiviCom Option is unvested, will be  assumed
    by  C-Cube and will automatically be converted  into an option to purchase a
    number of shares of C-Cube Common Stock determined by multiplying the number
    of shares of  DiviCom Common Stock  subject to the  unvested portion of  the
    DiviCom Option by the Unvested Exchange Ratio, at an exercise price equal to
    the  exercise price of the DiviCom Option  at the time of the Merger divided
    by the Unvested Exchange Ratio, rounded  down to the nearest whole cent.  To
    avoid fractional shares, the number of shares of C-Cube Common Stock subject
    to  an assumed  DiviCom Option  will be  rounded down  to the  nearest whole
    share. Subject to the treatment  of vested DiviCom Options described  below,
    the  other terms of  the DiviCom Options,  including vesting schedules, will
    remain unchanged. C-Cube has agreed to file a Registration Statement on Form
    S-8 with the Commission,  with respect to the  issuance of shares of  C-Cube
    Common  Stock  upon exercise  of  the assumed  DiviCom  Options, as  soon as
    practicable after the consummation of the Merger.
 
        THE VESTED PORTION OF DIVICOM OPTIONS WILL NOT BE ASSUMED BY C-CUBE, NOR
    IS C-CUBE SUBSTITUTING  ITS OPTIONS FOR  SUCH VESTED DIVICOM  OPTIONS. AS  A
    RESULT, EACH DIVICOM OPTION, TO THE EXTENT IT IS VESTED AND IS NOT EXERCISED
    ON OR BEFORE THE EFFECTIVE TIME, SHALL TERMINATE AND CEASE TO BE OUTSTANDING
    AS OF THE CONSUMMATION OF THE MERGER.
 
   
        As  of the DiviCom Record Date, there were [       ] outstanding DiviCom
    Options. Assuming that the vesting of such DiviCom Options is calculated  as
    of an assumed Merger consummation date of August 20, 1996, and assuming that
    as  of that date [         ] unvested DiviCom Options are assumed by C-Cube,
    between [          ] and [          ] shares of C-Cube Common Stock will  be
    subject  to such options, depending on the  Average Price and its effect, if
    any, on the Unvested Exchange Ratio.
    
 
                                       33

STOCK OWNERSHIP FOLLOWING THE MERGER
 
   
    Based upon (i) the capitalization of DiviCom as of the close of business  on
May  31,  1996, (ii)  the assumption  that  no holder  of DiviCom  Capital Stock
exercises appraisal or dissenters'  rights, (iii) a closing  date of August  20,
1996,  and (iv) an Average Price of $25.75, the closing price of C-Cube stock on
July 22, 1996, (the "Exchange Ratio Assumptions"), an aggregate of approximately
2,386,443 shares of C-Cube Common Stock  will be issued to DiviCom  stockholders
in the Merger. Based upon the number of shares of C-Cube Common Stock issued and
outstanding  as of  May 31,  1996, and  after giving  effect to  the issuance of
C-Cube Common Stock as described in the previous sentence, the former holders of
DiviCom Capital  Stock  would hold,  and  have  voting power  with  respect  to,
approximately     % of C-Cube's total issued and outstanding shares, and holders
of former DiviCom Options would hold options exercisable for approximately     %
of  C-Cube's total issued and outstanding  shares (assuming the exercise of only
such options). The foregoing  numbers of shares and  percentages are subject  to
change  in the event that the capitalization of either C-Cube or DiviCom changes
subsequent to May 31, 1996 and prior to the Effective Time, and there can be  no
assurance  as to the actual capitalization of C-Cube or DiviCom at the Effective
Time.
    
 
EMPLOYEE BENEFIT PLANS
 
    Representatives  of  C-Cube's  and  DiviCom's  respective  human   resources
departments  have met  and will  continue to  meet to  coordinate the  manner of
transition of the insurance and other benefit plans of DiviCom after the Merger.
C-Cube and  DiviCom intend  that the  continuing employees  of DiviCom  will  be
entitled  to  receive  employee  benefits  from C-Cube  that  will  be  at least
comparable to those being received by the employees of C-Cube, taken as a whole,
who occupy comparable positions and have comparable responsibilities.
 
    DIVICOM OPTIONS.    As  described  above,  pursuant  to  the  Reorganization
Agreement,  all unvested  DiviCom Options  outstanding immediately  prior to the
Effective Time will be assumed by  C-Cube and converted into options to  acquire
shares of C-Cube Common Stock. As of May 31, 1996, DiviCom Options to acquire an
aggregate   of  3,132,817  shares  of  DiviCom  Common  Stock  were  issued  and
outstanding of which 1,798,042 such options were unvested. Notice to the holders
of unvested DiviCom Options  as to the terms  of such assumption and  conversion
will  be sent by C-Cube  upon consummation of the  Merger. Each unvested DiviCom
Option so assumed by C-Cube shall continue to have, and be subject to, the  same
terms  and  conditions  set  forth  in the  related  option  plan  and/or option
agreement relating to such DiviCom Option. The vested portion of DiviCom Options
will be canceled and extinguished as of  the consummation of the Merger. At  the
Effective  Time, each  share will automatically  be converted into  the right to
receive that fraction of a  share of C-Cube Common  Stock equal to the  Unvested
Exchange Ratio. C-Cube will not assume DiviCom Options that are vested as of the
Effective  Time,  nor  will C-Cube  substitute  C-Cube options  for  such vested
DiviCom Options. To the extent that the vested DiviCom Options are not exercised
on or before the Effective Time, such options will terminate and cease to exist.
 
    C-Cube will take all  corporate and other actions  necessary to reserve  and
make  available  sufficient  shares of  C-Cube  Common Stock  for  issuance upon
exercise of the DiviCom Options assumed by  C-Cube and to prepare and file  with
the Commission a registration statement on Form S-8 (or any successor form) with
respect  to the underlying shares of  C-Cube Common Stock issuable upon exercise
of such DiviCom  Options. C-Cube will  use its reasonable  efforts to have  such
registration  statement declared effective as  soon as practicable following the
Effective Time and to maintain the effectiveness of such registration statement.
 
    SECTION 401(K) PLAN.   DiviCom has established  a tax-deferred savings  plan
(the "DiviCom Plan") qualified under Section 401(k) of the Internal Revenue Code
of 1986, as amended (the "Code"). Under the DiviCom Plan, eligible employees may
authorize voluntary payroll deductions of up to 15% of their base salaries to be
invested  in certain independently  managed, employee-selected investment funds.
DiviCom has the option  on an annual  or quarterly basis  to match or  partially
match any employee
 
                                       34
<PAGE>
contributions.  Following  the Merger,  DiviCom  employees will  be  eligible to
participate in  the  C-Cube  401(k)  Plan (the  "C-Cube  Plan")  by  making  new
contributions  to the C-Cube Plan.  It is presently intended  that the assets of
the DiviCom Plan will be transferred to the C-Cube Plan.
 
ESCROW FUND
 
   
    In connection with the Merger, at the  Effective Time, 10% of the shares  of
C-Cube  Common Stock (the "Escrow Shares")  otherwise issuable to each holder of
at least 1%  of the outstanding  shares of  DiviCom Capital Stock  prior to  the
Merger  on a fully diluted, as if  converted to Common Stock, basis with respect
to all options to acquire such stock (each a "Significant Stockholder") will  be
registered  in the name of and deposited  with the Escrow Agent, such deposit to
constitute the Escrow Fund. The Escrow Shares shall be contributed to the Escrow
Fund on behalf of  each Significant Stockholder in  proportion to the  aggregate
number  of  shares of  C-Cube Common  Stock  such Significant  Stockholder would
otherwise receive by virtue of the Merger. No portion of the Escrow Fund will be
contributed in  respect of  any options  to acquire  shares of  DiviCom  Capital
Stock.  The Escrow Shares will be held in escrow as security for any Losses that
C-Cube incurs. The Significant Stockholders will have voting rights with respect
to their respective Escrow Shares.  Resort to the Escrow  Fund will be the  sole
remedy  of C-Cube for  any Losses after the  Effective Time. Notwithstanding the
foregoing, C-Cube may  not receive any  shares from the  Escrow Fund unless  and
until  Losses in  excess of  $2,000,000 have been  suffered. For  the purpose of
compensating C-Cube for  its Losses, the  Escrow Shares shall  be valued at  the
average  of the closing prices  of C-Cube Common Stock  for the five consecutive
trading days ending  two days prior  to the  date such shares  are delivered  to
C-Cube  out of the Escrow  Fund. Subject to resolution  of unsatisfied claims of
C-Cube, the Escrow  Fund shall  terminate upon  on the  date which  is 270  days
following  the closing of the Merger.  The rights of Significant Stockholders to
receive Escrow  Shares upon  the termination  of  the Escrow  Fund will  not  be
evidenced  other than by  the Reorganization Agreement  and any escrow agreement
that may be  entered into with  the Escrow  Agent. The shares  of C-Cube  Common
Stock  subject to the escrow  may be voted by  the Significant Stockholders and,
subject to the effect of the  escrow and other applicable transfer  restrictions
(including  the  Affiliate Agreements),  may be  transferred by  the Significant
Stockholders.
    
 
    BY APPROVING THE REORGANIZATION AGREEMENT, THE SIGNIFICANT STOCKHOLDERS WILL
BE DEEMED TO HAVE  CONSENTED TO THE APPOINTMENT  OF NOLAN DAINES, PRESIDENT  AND
CHIEF  EXECUTIVE OFFICER OF DIVICOM, AND  CAROLINE DE PUYSEGUR, A REPRESENTATIVE
OF THE  SAGEM  ENTITIES,  TO ACT  AS  THE  SECURITYHOLDER AGENTS  ON  BEHALF  OF
DIVICOM'S  SIGNIFICANT  STOCKHOLDERS TO  AUTHORIZE  DELIVERY OF  SHARES  HELD IN
ESCROW TO C-CUBE  IN SATISFACTION  OF CLAIMS BROUGHT  BY C-CUBE  FOR LOSSES,  TO
OBJECT  TO  SUCH  DELIVERIES,  TO  AGREE TO,  TO  NEGOTIATE  AND  TO  ENTER INTO
SETTLEMENTS AND COMPROMISES  WITH RESPECT TO  SUCH CLAIMS, AND  TO TAKE  CERTAIN
OTHER  ACTIONS ON BEHALF OF DIVICOM'S  SIGNIFICANT STOCKHOLDERS. SEE ARTICLE VII
OF THE REORGANIZATION AGREEMENT  FOR A MORE DETAILED  EXPLANATION OF THE  ESCROW
FUND AND RIGHTS WITH RESPECT THERETO.
 
LEGAL STRUCTURE OF THE MERGER
 
    Under  the Reorganization Agreement, DiviCom will merge with and into Merger
Sub, a wholly owned  subsidiary of C-Cube formed  for this purpose, with  Merger
Sub being the surviving corporation of the Merger (the "Surviving Corporation").
The  Certificate of Incorporation and Bylaws of Merger Sub in effect immediately
prior to the  Effective Time will  remain the Certificate  of Incorporation  and
Bylaws  of the Surviving  Corporation and the  Board of Directors  of Merger Sub
will remain the Board of Directors of the Surviving Corporation. The officers of
DiviCom immediately prior to the Effective Time will be the initial officers  of
the  Surviving Corporation, each to hold office in accordance with the Bylaws of
the Surviving Corporation.
 
CONDUCT OF DIVICOM'S BUSINESS PRIOR TO THE MERGER
 
    Under the Reorganization  Agreement, DiviCom has  agreed, during the  period
from  the date of the Reorganization  Agreement and continuing until the earlier
of the termination of the Reorganization Agreement pursuant to its terms or  the
Effective  Time, except to the extent that C-Cube otherwise consents in writing,
that DiviCom  will carry  on its  business in  the usual,  regular and  ordinary
course  in substantially  the same  manner as  previously conducted,  to pay its
debts and taxes
 
                                       35

material portion of its capital stock  or assets, (iii) enter into an  agreement
with  any person,  other than C-Cube,  providing for the  acquisition of DiviCom

respect to their shares by  virtue of the Merger,  (i) the Commission shall  not
have  required as a condition to declaring this registration statement effective
any material change in C-Cube's proposed  accounting for the Merger, (j)  C-Cube
shall  be reasonably satisfied that the  Merger will constitute a reorganization
within the meaning of Section 368(a) of the Code.
 
TERMINATION OF REORGANIZATION AGREEMENT
 
    The Reorganization Agreement provides that it may be terminated at any  time
prior  to the Effective Time, whether before  or after approval of the Merger by
DiviCom's stockholders, (a) by mutual consent of DiviCom, the SAGEM Entities and
C-Cube, (b) by C-Cube, the SAGEM Entities or DiviCom if: (i) the Effective  Time
has  not occurred by August  31, 1996 (provided that  the right to terminate the
Reorganization Agreement under  this clause (b)  shall not be  available to  any
party  whose willful failure to fulfill  any obligation under the Reorganization
Agreement has been the cause  of, or resulted in,  the failure of the  Effective
Time to occur on or before such date); (ii) there shall be a final nonappealable
order  of a  federal or  state court  in effect  preventing consummation  of the
Merger; or (iii) there shall be any statute, rule, regulation or order  enacted,
promulgated  or issued  or deemed applicable  to the Merger  by any governmental
entity that would  make consummation  of the Merger  illegal, (c)  by C-Cube  if
there  shall be  any action  taken, or  any statute,  rule, regulation  or order
enacted, promulgated  or issued  or  deemed applicable  to  the Merger,  by  any
governmental  entity, which would: (i)  prohibit C-Cube's or DiviCom's ownership
or operation of any portion of the business of DiviCom or (ii) compel C-Cube  or
DiviCom  to dispose of or hold separate, as  a result of the Merger, any portion
of  the  business  or  assets  of  DiviCom  or  C-Cube;  in  either  case,   the
unavailability  of which assets or business would have a material adverse effect
on C-Cube's ability  to realize the  benefits expected from  the Merger; (d)  by
C-Cube   if  it  is  not  in  material  breach  of  its  obligations  under  the
 
                                       39
<PAGE>
Reorganization Agreement  and there  has been  a breach  of any  representation,
warranty, covenant or agreement contained in the Reorganization Agreement on the
part  of DiviCom and as a result of such breach certain conditions to the Merger
set forth above  would not then  be satisfied; provided,  however, that if  such
breach  is curable  by DiviCom  within thirty days  through the  exercise of its
reasonable best efforts, then for so long as DiviCom continues to exercise  such
reasonable  best efforts C-Cube  may not terminate  the Reorganization Agreement
under this clause (d) unless such breach is not cured within thirty days (but no
cure period shall be required for a breach which by its nature cannot be cured);
(e) by DiviCom  if it is  not in material  breach of its  obligations under  the
Reorganization  Agreement and  there has  been a  breach of  any representation,
warranty, covenant or agreement contained in the Reorganization Agreement on the
part of C-Cube or Merger Sub and  as a result of such breach certain  conditions
to  the Merger set forth  above would not then  be satisfied; provided, however,
that if  such breach  is curable  by C-Cube  or Merger  Sub within  thirty  days
through  the exercise of C-Cube's or  Merger Sub's reasonable best efforts, then
for so long as C-Cube or Merger  Sub continues to exercise such reasonable  best
efforts DiviCom may not terminate the Reorganization Agreement under this clause
(e) unless such breach is not cured within thirty days (but no cure period shall
be required for a breach which by its nature cannot be cured); and (f) by C-Cube
if  DiviCom shall  not have  obtained the  approval of  its stockholders  to the
Merger and the transactions contemplated by this Agreement by thirty days  after
the effective date of this registration statement.
 
TRANSITION AGREEMENT
 
   
    In  connection  with  the  Reorganization  Agreement,  the  SAGEM  Entities,
DiviCom, C-Cube and Nolan Daines entered into a Transition Agreement pursuant to
which they  agreed  to  terminate,  as of  the  Effective  Time,  five  existing
agreements  (the "Prior Agreements") to  which all or some  of them are parties:
(i) the Joint Venture and Shareholders Agreement, dated April 20, 1993; (ii) the
Business Agreement, dated as  of April 20, 1993;  (iii) the Registration  Rights
and  Buy-Out  Agreement,  dated as  of  April  20, 1993;  (iv)  the  1995 Rap-Up
Agreement, dated January 23, 1996; and (v) the ASIC Purchasing Agreement,  dated
January  23,  1996.  The Prior  Agreements  concerned, among  other  things, the
licensing and allocation of technology  ownership between DiviCom and the  SAGEM
Entities,  and  the supply  of products  to the  SAGEM Entities.  The Transition
Agreement assigns, as of  the Effective Time, to  DiviCom all rights  (including
all  intellectual property rights)  that any party  thereto (other than DiviCom)
may have in any  technology related to any  products manufactured, designed,  or
sold  by DiviCom.  Under the Transition  Agreement, DiviCom grants  to the SAGEM
Entities certain non-exclusive licenses under certain DiviCom technology.  These
licenses  are  perpetual, irrevocable,  non-transferable,  and non-sublicensable
(except to affiliates). In particular, the SAGEM Entities are granted a  license
under  the  DiviCom technology,  including  DiviCom's ASIC  designs,  to design,
manufacture, distribute, make derivative products from and sell certain  decoder
products,  consumer  decoders and  SAGEM-developed  decoders. These  licenses in
general continue  licensing arrangements  that  were in  place under  the  Prior
Agreements. None of these licenses entitle the SAGEM Entities to receive updated
versions  of DiviCom technology, and, in  most instances, the DiviCom technology
that is licensed is limited to the December 31, 1995 version thereof. Royalties,
on a  per unit  basis,  are payable  by the  SAGEM  Entities on  SAGEM  products
manufactured  and sold under these licenses for three years from the date of the
Transition Agreement. Thereafter, the licenses  continue in perpetuity as  fully
paid-up licenses.
    
 
    In  addition, the Transition Agreement provides  the SAGEM Entities with the
right to  distribute,  and  to  provide customer  support  for,  DiviCom  system
products  in Europe. This license is  non-exclusive; however during the two-year
term of such license, DiviCom will, to the extent permitted by law, not  license
any  third party  to sell  or lease or  otherwise distribute  DiviCom systems in
France. The SAGEM Entities  have the right to  purchase certain system  products
from  DiviCom, for  distribution and sale  by SAGEM,  on a most-favored-customer
basis. DiviCom also agrees to provide the SAGEM Entities' customers support on a
most-favored-customer basis with respect to  DiviCom products sold by the  SAGEM
Entities prior to the date of the Transition Agreement.
 
                                       40
<PAGE>
    In  addition to the foregoing  provisions, the Transition Agreement includes
terms regarding, among other things, the supply of ASICs to the SAGEM  Entities,
representations   and  warranties,  limitations   of  liability,  protection  of
confidential information  and  other terms  relevant  to an  agreement  for  the
transfer and licensing of technology.
 
REGISTRATION RIGHTS AGREEMENT
 
    Pursuant  to the terms  of the Reorganization  Agreement, the SAGEM Entities
entered into a Registration Rights Agreement with C-Cube which grants the  SAGEM
Entities  certain rights to have their shares of C-Cube Common Stock obtained as
a  result  of  the  Merger  registered  under  the  Securities  Act.  Under  the
Registration  Rights Agreement, the  SAGEM Entities may, on  up to two occasions
beginning 90 days after the effective date of the Merger and ending on the third
anniversary of the Closing Date,  require C-Cube to register  on a Form S-3  not
less  than 10% of the  SAGEM Entities' shares of  C-Cube Common Stock. C-Cube is
only obligated to effect such a registration once every 365 days, provided  that
such  period may be shortened to 180 days  in the event that the SAGEM Entities'
shares of  C-Cube  Common  Stock  exceed  the greater  of  (i)  1%  of  C-Cube's
outstanding  Common Stock and (ii) the  average weekly reported volume of public
trading in C-Cube Common  Stock during the preceding  four full calendar  weeks.
C-Cube  may delay the filing  or effectiveness of such  registration by up to 90
days  in  the  event  such  registration  would  interfere  with  a  significant
transaction   involving  C-Cube  or  in  the  event  C-Cube  is  working  on  an
underwritten public offering of C-Cube Common  Stock and the SAGEM Entities  are
afforded an opportunity to include at least 50% of their shares of C-Cube Common
Stock in such offering.
 
    Additionally,  pursuant to the  Registration Rights Agreement,  in the event
C-Cube proposes to  register shares of  C-Cube Common Stock  for the account  of
selling  securityholders, then C-Cube must generally include the SAGEM Entities'
shares of C-Cube Common Stock in such registration on a PRO RATA basis to  those
of the other selling securityholders.
 
    C-Cube  is  required to  pay all  expenses  of a  registration of  the SAGEM
Entities' shares  of C-Cube  Common Stock  pursuant to  the Registration  Rights
Agreement,  except for discounts, commissions  and fees of underwriters, selling
brokers and dealers relating to such shares, and any fees of the SAGEM Entities'
counsel.
 
    The Registration Rights  Agreement requires  C-Cube to  indemnify the  SAGEM
Entities   and  their  directors  and  officers  and  any  underwriter  for  any
liabilities or losses relating  to any untrue (or  alleged untrue) statement  or
misleading  (or alleged  misleading) omission  made by  C-Cube and  requires the
SAGEM Entities  to indemnify  C-Cube  and its  directors  and officers  and  any
underwriter under similar circumstances.
 
VOTING AGREEMENT
 
   
    The  SAGEM Entities own in the  aggregate 2,046,217 shares of DiviCom Common
Stock and 20,723,855 shares  of DiviCom Preferred  Stock representing 18.5%  and
97.3%  of the votes entitled  to be cast by holders  of shares of DiviCom Common
Stock and DiviCom Preferred  Stock, respectively, issued  and outstanding as  of
May  31, 1996. Each of these entities, as well as the CEO (who beneficially owns
a total of 1,877,895 shares  of DiviCom Common Stock representing  approximately
16.98% of the number of shares of DiviCom Common Stock outstanding as of May 31,
1996) of DiviCom, have entered into a Voting Agreement with C-Cube. In addition,
C-Cube and its affiliates hold 3.6% of the Series A Preferred Stock and 12.4% of
the  Common Stock of DiviCom and  intend to vote in favor  of the Merger and the
Certificate Amendment. Each of  the foregoing entities  and individual has  been
identified by DiviCom as an "affiliate" (as that term is defined for purposes of
Rule  145  promulgated under  the Securities  Act) of  DiviCom. Pursuant  to the
Voting Agreement, each of the foregoing DiviCom stockholders has agreed to  vote
in  favor of approval and adoption  of the Reorganization Agreement and approval
of the Merger.
    
 
    The vote  of the  shares of  DiviCom  Capital Stock  subject to  the  Voting
Agreement  will be adequate to approve  the Reorganization Agreement, the Merger
and the Certificate Amendment by DiviCom stockholders.
 
                                       41
<PAGE>
NONCOMPETITION AGREEMENTS
 
    Certain  officers  and  other  employees   of  DiviCom  have  entered   into
noncompetition agreements with C-Cube and DiviCom. The restrictions contained in
such  agreements cease  if the  restricted party's  employment is  terminated by
C-Cube or DiviCom and  C-Cube does not elect  to continue paying the  restricted
party's  salary during the  remainder of the  noncompetition period ending three
years after the Effective Time.
 
AFFILIATE AGREEMENTS
 
    The C-Cube Common Stock to be issued  pursuant to the Merger will be  freely
transferable  under the Securities  Act, except for shares  issued to any person
who is an "affiliate" of C-Cube or  DiviCom within the meaning of Rules 144  and
145  under the  Securities Act.  Rules 144  and 145  impose restrictions  on the
manner in which such affiliates may  resell securities and also on the  quantity
of  securities  that such  affiliates and  others  with whom  they might  act in
concert may resell within any three-month period.
 
    In connection with the parties  entering into the Reorganization  Agreement,
each  person who has  been identified by  DiviCom as an  affiliate of DiviCom is
required to  have entered  into an  agreement with  C-Cube providing  that  such
person  will not offer to  sell or otherwise dispose  of any C-Cube Common Stock
obtained as a result of the Merger except in compliance with the Securities  Act
and the rules and regulations thereunder. Generally, this will require that such
sales  be made in accordance with Rule 145(d) under the Securities Act, which in
turn requires that, for specified periods, such sales be made in compliance with
the volume  limitations,  manner  of sale  provisions  and  current  information
requirements of Rule 144 under the Securities Act. The volume limitations should
not  pose any material limitations on any  C-Cube stockholder who owns less than
one percent of  the outstanding  C-Cube Common  Stock after  the Merger  unless,
pursuant  to Rule 144,  such stockholder's shares are  required to be aggregated
with those  of another  stockholder and  together they  exceed the  one  percent
threshold.
 
    The  affiliate agreements  executed by each  affiliate of  DiviCom contain a
representation that such affiliate has no plan  or intention to sell any of  the
shares of C-Cube Common Stock received in the Merger (and will have no such plan
or intention at the Effective Time).
 
CERTAIN BENEFITS TO DIVICOM MANAGEMENT AND EMPLOYEES
 
   
    DiviCom has forgiven the non-interest bearing obligation of Nolan Daines and
Tom  Lookabaugh  to repay  $73,342.10 and  $48,671.05, respectively,  that would
otherwise be due from them under certain Executive Compensation Agreements as  a
result  of  the  Merger. These  amounts  had  been paid  to  Messrs.  Daines and
Lookabaugh as a bonus in 1995 by DiviCom. Although Messrs. Daines and Lookabaugh
recognized such amounts as taxable income, the Executive Compensation Agreements
required them to repay the bonuses if DiviCom were acquired. DiviCom's Board  of
Directors  has  decided to  waive this  obligation.  Options granted  to certain
DiviCom officers, including Nolan Daines,  Brian Johnson and Thomas  Lookabaugh,
contain   provisions  that  require  DiviCom   to  achieve  certain  development
milestones in order for such options  to vest. Furthermore, Eurodec, one of  the
SAGEM Entities, is to make the determination of whether the milestones have been
achieved  and  provide  written  notice to  that  effect.  DiviCom  achieved the
milestones in  October  1995, but  has  not  received the  written  notice  from
Eurodec. The Transition Agreement that will be effective upon the Closing of the
Merger  acknowledges the achievement  of such milestones.  Eurodec has agreed to
provide such  written  notice, which  will  have  the effect  of  ratifying  the
achievement  in  October  1995. The  SAGEM  Entities have  been  granted certain
licenses and  distribution  rights  under  the  Transition  Agreement.  See  "--
Transition Agreement."
    
 
CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
   
    The  following discussion summarizes certain of the principal federal income
tax considerations of  the Merger that  are generally applicable  to holders  of
DiviCom  Capital Stock and is based on  the opinions of counsel described below.
This discussion does  not deal with  all income tax  considerations that may  be
relevant  to  particular  DiviCom  stockholders  in  light  of  their particular
circumstances,
    
 
                                       42
<PAGE>
such  as  stockholders   who  are  dealers   in  securities,  foreign   persons,
stockholders  who  acquired their  shares  in connection  with  previous mergers
involving DiviCom or an affiliate, or stockholders who acquired their shares  in
connection  with stock option  or stock purchase plans  or in other compensatory
transactions. In addition,  the following  discussion does not  address the  tax
consequences  of transactions effectuated prior to  or after the Merger (whether
or not such transactions are in  connection with the Merger), including  without
limitation  transactions in  which shares of  DiviCom Capital Stock  were or are
acquired or shares of C-Cube Common Stock were or are disposed of.  Furthermore,
no foreign, state or local tax considerations are addressed herein. ACCORDINGLY,
DIVICOM  STOCKHOLDERS ARE  URGED TO  CONSULT THEIR  OWN TAX  ADVISORS AS  TO THE
SPECIFIC TAX  CONSEQUENCES  OF THE  MERGER,  INCLUDING THE  APPLICABLE  FEDERAL,
STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER.
 
    The  Merger  is intended  to  constitute a  "reorganization"  under Sections
368(a)(1)(A) and 368(a)(2)(D) of the Internal  Revenue Code of 1986, as  amended
(the  "Code"), with the result that, as  discussed more fully below, (i) none of
C-Cube, DiviCom or Merger Sub should recognize  gain or loss as a result of  the
Merger  and (ii) holders of DiviCom Capital Stock that exchange their shares for
Common Stock and cash should recognize any  realized gain (but not loss) in  the
Merger but not in excess of the amount of cash received.
 
    Assuming  that the Merger qualifies as a reorganization, that DiviCom is not
a "collapsible corporation" within  the meaning of Section  341 of the Code  and
that the DiviCom Capital Stock exchanged and the C-Cube Common Stock received by
each  DiviCom  stockholder are  held  as capital  assets  within the  meaning of
Section 1221 of the Code, the following tax consequences should result:
 
    GENERAL.  A DiviCom stockholder will not recognize any loss upon the receipt
of C-Cube Common  Stock and cash.  A DiviCom stockholder  receiving both  C-Cube
Common  Stock and cash in exchange for DiviCom Capital Stock will recognize gain
(measured by  the sum  of  the fair  market value  of  the C-Cube  Common  Stock
received  plus the amount of any cash received minus the tax basis of the shares
of DiviCom Capital  Stock exchanged),  if any,  but only  to the  extent of  the
amount of any cash received. Under applicable U.S. Supreme Court precedent, such
gain  should  generally  be capital  gain,  subject to  recharacterization  as a
dividend as  described  more fully  below,  and should  generally  be  long-term
capital gain if the shares of DiviCom Capital Stock exchanged for cash have been
held for more than one year.
 
    The  tax basis  of the  C-Cube Common  Stock received  (including the Escrow
Stock as defined herein -- see "Terms of the Merger -- Escrow Fund") will be the
same as the tax basis of the  DiviCom Capital Stock exchanged, decreased by  (i)
the  basis of any  fractional share interest  for which cash  is received in the
Merger and (ii) the amount  of cash received at  the Effective Time (other  than
cash  received for a fractional share interest),  and increased by the amount of
gain (or dividend income) recognized on the exchange.
 
    In certain  circumstances,  a  DiviCom stockholder  that  exchanges  DiviCom
Capital  Stock for C-Cube Common  Stock in the Merger  will be required to treat
any gain recognized as dividend income (rather than capital gain, if any) up  to
the  amount  of cash  received in  the Merger  if  the receipt  of cash  by such
stockholder has the effect of a distribution of a dividend. Whether the  receipt
of  cash has the effect of the distribution  of a dividend would depend upon the
stockholder's particular circumstances.
 
    In general, the determination of whether a stockholder who exchanges DiviCom
Capital Stock and receives C-Cube Common Stock and cash recognizes capital  gain
or  dividend income is made under Sections  356(a)(2) and 302 of the Code. Under
Section 356(a)(2) of the Code, each stockholder of DiviCom Capital Stock will be
treated for tax purposes as if such stockholder had received only C-Cube  Common
Stock  in the Merger, and immediately thereafter C-Cube had redeemed appropriate
portions of  such  C-Cube  Common  Stock  in  exchange  for  the  cash  actually
distributed  to such stockholder in  the Merger. Under Section  302 of the Code,
the gain recognized by a  stockholder on the exchange  will be taxed as  capital
gain  if the  deemed redemption  from such  stockholder (i)  is a "substantially
disproportionate redemption" of stock with respect to such stockholder, or  (ii)
is  "not essentially equivalent to a dividend" with respect to such stockholder.
In making this determination, stockholders should be
 
                                       43
<PAGE>
aware that, under Section 318  of the Code, a  stockholder may be considered  to
own,   after  the  Merger,  C-Cube  Common   Stock  owned  (and  in  some  cases
constructively owned) by  certain related  individuals and  entities and  C-Cube
Common Stock which the stockholder (or such related individuals or entities) has
the right to acquire upon the exercise or conversion of options.
 
    The deemed redemption of a DiviCom stockholder's C-Cube Common Stock will be
a  "substantially disproportionate  redemption" if,  as a  result of  the deemed
redemption, the ratio  determined by  dividing the  number of  shares of  C-Cube
Common Stock owned by such stockholder immediately after the Merger by the total
number of outstanding shares of C-Cube Common Stock is less than 80% of the same
ratio  calculated as if only  C-Cube Common Stock, and  not cash, were issued to
the DiviCom stockholder in the Merger.
 
    The deemed redemption of  a stockholder's C-Cube Common  Stock will be  "not
essentially   equivalent  to  a  dividend"  if  the  stockholder  experiences  a
"meaningful reduction" in his or her proportionate equity interest in C-Cube  by
reason  of  the  deemed  redemption.  Although  there  are  no  fixed  rules for
determining when  a  meaningful reduction  has  occurred, the  Internal  Revenue
Service (the "IRS") has indicated in a published ruling that the receipt of cash
in  the Merger  would not  be characterized as  a dividend  if the stockholder's
percentage ownership interest  in C-Cube  and DiviCom  prior to  the Merger  was
minimal,  the stockholder  exercises no  control over  the affairs  of C-Cube or
DiviCom, and  the  stockholder's  percentage ownership  interest  in  C-Cube  is
reduced  in the deemed  redemption by any  extent. If neither  of the redemption
tests set forth above are satisfied,  the stockholder will be treated as  having
received  a dividend equal to the  amount of such stockholder's recognized gain,
assuming that such stockholder's  ratable share of the  earnings and profits  of
DiviCom (and, possibly, C-Cube) equals or exceeds such recognized gain.
 
    RETURN  OF ESCROW  STOCK.  Upon  a return of  the Escrow Stock  to C-Cube, a
DiviCom stockholder may recognize gain or loss. If gain is recognized, the value
of any shares  of Escrow Stock  returned to C-Cube  should be added  to the  tax
basis of the C-Cube Common Stock held by such stockholder.
 
    DISSENTING   STOCKHOLDERS.    A  DiviCom  stockholder  that  exercises  such
stockholder's right to seek an appraisal of such stockholder's shares of DiviCom
Capital Stock generally  will recognize  capital gain  or loss  measured by  the
difference  between the amount of cash received  and the tax basis of the shares
of DiviCom Capital Stock exchanged therefor.  Such capital gain or loss will  be
long-term  capital gain or loss if the shares of DiviCom Capital Stock exchanged
by such  dissenting  stockholder have  been  held for  more  than one  year.  In
addition,  the amount of cash received may  be treated as dividend income if the
dissenting stockholder actually or constructively owns C-Cube Common Stock after
the Merger as discussed above.
 
    FRACTIONAL SHARES.  If a holder of shares of DiviCom Capital Stock  receives
cash  in lieu of a  fractional share of C-Cube Common  Stock in the Merger, such
cash amount will be treated as received in exchange for the fractional share  of
C-Cube  Common Stock. Gain or loss recognized  as a result of that exchange will
be equal to the cash amount received  for the fractional share of C-Cube  Common
Stock  reduced by the proportion of the  holder's tax basis in shares of DiviCom
Capital Stock exchanged and allocable to  the fractional share of C-Cube  Common
Stock. Such gain or loss will be long-term capital gain or loss if the shares of
DiviCom Capital Stock exchanged therefor have been held for more than one year.
 
   
    The  parties are not requesting a ruling from the IRS in connection with the
Merger. However, it is a condition to the consummation of the Merger that C-Cube
be reasonably satisfied  that the Merger  will qualify as  a reorganization  and
C-Cube does not intend to waive this condition. Accordingly, the consummation of
the  Merger is conditioned on the delivery of the opinions of Fenwick & West LLP
and Wilson, Sonsini, Goodrich & Rosati, Professional Corporation, to the  effect
that,   for  federal  income   tax  purposes,  the   Merger  will  constitute  a
"reorganization" within  the  meaning  of  Section 368(a)  of  the  Code.  These
opinions,  which  are collectively  referred to  herein  as the  "Tax Opinions,"
neither bind the IRS nor preclude the IRS from adopting a contrary position.  In
addition,  the Tax Opinions  are based upon (i)  representations made by C-Cube,
Merger Sub, DiviCom and certain stockholders of
    
 
                                       44
<PAGE>
   
DiviCom and (ii) the  assumption that the  "continuity of interest"  requirement
for  tax-free  reorganization  treatment  will  be  satisfied.  In  general, the
continuity of interest requirement  will be satisfied if  (i) the C-Cube  Common
Stock received in the Merger, in the aggregate, represents a substantial portion
of  the entire consideration received by  the DiviCom stockholders in the Merger
and (ii) the DiviCom stockholders do not  pursuant to a plan or intent  existing
at the time of the Merger dispose of so much of the C-Cube Common Stock received
in  the  Merger  that the  DiviCom  stockholders  no longer  have  a substantial
proprietary interest in the DiviCom business being conducted by C-Cube after the
Merger. DiviCom  stockholders should  be  aware that  the  law relating  to  the
continuity  of interest requirement is unclear  and the Internal Revenue Service
could argue that post-Merger sales, if any, by former DiviCom stockholders could
result in the Merger failing to qualify as a reorganization.
    
 
    A successful IRS challenge to the "reorganization" status of the Merger  (as
a  result of a failure of the "continuity of interest" requirement or otherwise)
would generally result in a DiviCom  stockholder recognizing the full amount  of
his  or her  gain or loss  with respect to  each share of  DiviCom Capital Stock
surrendered equal  to the  difference between  the stockholder's  basis in  such
share  and the fair market value, as of the Effective Time of the Merger, of the
C-Cube Common Stock received in exchange therefor plus the cash received.
 
   
    THE PRECEDING DISCUSSION  IS INTENDED ONLY  AS A SUMMARY  OF CERTAIN  UNITED
STATES  INCOME  TAX CONSEQUENCES  OF THE  MERGER AND  DOES NOT  PURPORT TO  BE A
COMPLETE ANALYSIS OR DISCUSSION OF  ALL POTENTIAL TAX EFFECTS RELEVANT  THERETO.
THUS, DIVICOM STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC  TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING TAX RETURN REPORTING
REQUIREMENTS, THE APPLICABILITY  AND EFFECT OF  FOREIGN, FEDERAL, STATE,  LOCAL,
AND  OTHER APPLICABLE TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX
LAWS.
    
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
    C-Cube and  DiviCom are  aware of  no governmental  or regulatory  approvals
required  for consummation of the  Merger, other than the  filing of a Premerger
Notification and Report Form with the Federal Trade Commission and the Antitrust
Division  of  the  Department  of  Justice  pursuant  to  the  Hart-Scott-Rodino
Antitrust  Improvements Act of 1976 and  compliance with federal securities laws
and the applicable securities laws of the various states.
 
ACCOUNTING TREATMENT
 
   
    The Merger  will be  accounted for  as a  purchase for  financial  reporting
purposes  in accordance  with generally  accepted accounting  principles. C-Cube
currently anticipates  expensing  approximately $105.4  million  for  in-process
research  and development expenses upon the  closing of the Merger. Consummation
of the Merger is conditioned on the  Commission not requiring as a condition  to
declaring  this Registration/Proxy  Statement effective  any material  change in
C-Cube's proposed accounting for the Merger.
    
 
APPRAISAL AND DISSENTERS' RIGHTS
 
   
    Stockholders of DiviCom who do  not vote in favor  of the Merger may,  under
certain  circumstances and  by following the  procedure prescribed  by the DGCL,
exercise appraisal rights and receive cash  for their shares of DiviCom  Capital
Stock. A dissenting stockholder must follow the appropriate procedures under the
DGCL  or  suffer the  termination or  waiver of  such rights.  The failure  of a
DiviCom stockholder to vote on the  Merger will not constitute a termination  or
waiver of such stockholder's appraisal and dissenter's rights under the DGCL.
    
 
   
    Each  holder of  DiviCom Capital Stock  who is entitled  to appraisal rights
shall have 120  days after the  Effective Time  of the Merger  to exercise  such
appraisal rights. Such stockholder must file a petition in the Delaware Court of
Chancery  demanding a determination  of the value of  its DiviCom Capital Stock.
Merger Sub will send  a statement setting forth  the aggregate number of  shares
not
    
 
                                       45
<PAGE>
   
voted  in favor of the  Merger to all stockholders  entitled to appraisal rights
who perfected such rights and submitted  written requests for such statement  to
Merger Sub within 120 days after the Effective Time of the Merger.
    
 
    If  a  holder  of  DiviCom  Capital  Stock  exercises  appraisal  rights  in
connection with the Merger  under Section 262 of  the DGCL ("Section 262"),  any
shares  of  DiviCom Capital  Stock in  respect  of which  such rights  have been
exercised and  perfected will  not be  converted into  C-Cube Common  Stock  but
instead will be converted into the right to receive such consideration as may be
determined  by  the Delaware  Court of  Chancery  (the "Court")  to be  due with
respect to such  shares pursuant  to the  laws of  the State  of Delaware.  This
Prospectus/Proxy  Statement is being sent by personal delivery or by mail to all
holders of record of shares of DiviCom Capital Stock on the DiviCom Record  Date
and  constitutes notice of the appraisal  rights available to such holders under
Section 262.
 
    The following summary of the provisions of Section 262 is not intended to be
a complete statement  of such  provisions and is  qualified in  its entirety  by
reference  to the full text of Section 262,  a copy of which is attached to this
Prospectus/Proxy Statement as Annex B and incorporated herein by reference.
 
    Holders of shares of DiviCom Capital Stock who object to the Merger and  who
follow  the procedures in Section  262 will be entitled  to have their shares of
DiviCom Capital Stock appraised by the Court and to receive payment of the "fair
value" of such shares as of the Effective Time of the Merger.
 
    A stockholder of DiviCom electing  to exercise appraisal rights must,  prior
to  the vote concerning the  Merger at the DiviCom  Meeting, perfect his, her or
its appraisal rights by demanding in writing from DiviCom the appraisal of  his,
her  or its shares of DiviCom Capital Stock.  A vote against the Merger will not
constitute a demand for  appraisal. A stockholder electing  to take such  action
must do so by a separate written demand as provided in Section 262. A holder who
elects  to exercise  appraisal rights  should mail  or deliver  his, her  or its
written demand  to  DiviCom at  1708  McCarthy Boulevard,  Milpitas,  California
95035.  The demand  should specify  the holder's  name and  mailing address, the
number of  shares  of  DiviCom Capital  Stock  owned  and that  such  holder  is
demanding  appraisal  of his,  her  or its  shares.  Within ten  days  after the
Effective Time of the Merger, DiviCom must provide notice of the Effective  Time
of  the Merger to all  stockholders who have complied  with Section 262 and have
not voted in favor of approval and adoption of the Reorganization Agreement  and
approval  of the Merger.  Only a holder  of record of  shares of DiviCom Capital
Stock (or his, her or its  duly appointed representative) is entitled to  assert
appraisal rights for the shares registered in that holder's name.
 
    Within  120 days after the Effective Time of the Merger, any stockholder who
has made a valid written demand and who  has not voted in favor of approval  and
adoption of the Reorganization Agreement and approval of the Merger may (i) file
a  petition in  the Court demanding  a determination  of the value  of shares of
DiviCom Capital Stock,  and (ii) upon  written request, receive  from DiviCom  a
statement  setting forth the aggregate number of shares of DiviCom Capital Stock
not voted in favor of approval and adoption of the Reorganization Agreement  and
approval of the Merger and with respect to which demands for appraisal have been
received and the aggregate number of holders of such shares. Such statement must
be  mailed within ten days after the  written request therefor has been received
by DiviCom.
 
    If a  petition for  an  appraisal is  timely filed,  at  a hearing  on  such
petition,  the Court is  required to determine the  holders of Dissenting Shares
entitled to appraisal rights and to determine the "fair value" of the Dissenting
Shares exclusive of  any element  of value  arising from  the accomplishment  or
expectation  of the Merger, together with a fair rate of interest, if any, to be
paid upon the value of the Dissenting Shares. In determining such "fair  value",
the  Court is required to take into  account all relevant factors, including the
market value of DiviCom Capital  Stock and the net  asset and earnings value  of
DiviCom,  and in determining the fair value  of interest, the Court may consider
the rate of interest which DiviCom would have had to pay to borrow money  during
the pendency of the proceeding. Upon application by a stockholder, the Court may
also order that all or a portion of the expenses
 
                                       46
<PAGE>
incurred  by  any  stockholder  in  connection  with  the  appraisal proceeding,
including, without  limitation,  reasonable attorneys'  fees  and the  fees  and
expenses  of experts utilized  in the appraisal proceeding,  be charged pro rata
against the  value  of all  the  shares of  DiviCom  Capital Stock  entitled  to
appraisal.
 
    Any  holder of  Dissenting Shares who  has duly demanded  an appraisal under
Section 262 will not,  after the Effective  Time of the  Merger, be entitled  to
vote  the shares subject  to such demand for  any purpose or  be entitled to the
payment of dividends or  other distributions on  such Dissenting Shares  (except
dividends  or other distributions payable to stockholders of record as of a date
prior to the Effective Time of the Merger).
 
    If any holder of shares of DiviCom Capital Stock who demands appraisal under
Section 262 effectively withdraws or loses, his, her or its right to  appraisal,
the  shares of such holder will be converted into a right to receive that number
of shares  of  C-Cube Common  Stock  as is  determined  in accordance  with  the
Reorganization  Agreement. A holder will effectively lose his right to appraisal
if he, she or it votes in  favor of approval and adoption of the  Reorganization
Agreement  and approval of the Merger, or  if no petition for appraisal is filed
within 120  days after  the  Effective Time  of the  Merger,  or if  the  holder
delivers  to  DiviCom  a  written  withdrawal of  such  holder's  demand  for an
appraisal and  an acceptance  of the  Merger, except  that any  such attempt  to
withdraw  made more than 60 days after the Effective Time of the Merger requires
the written approval of DiviCom. A  holder of stock represented by  certificates
may  also lose  his, her or  its right to  appraisal if  he, she or  it fails to
comply with the Court's  direction to submit such  certificates of stock to  the
Register  in  Chancery for  notation thereon  of the  pendency of  the appraisal
proceedings.

                               C-CUBE AND DIVICOM
          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
   
    The  following unaudited  pro forma condensed  combined financial statements
give effect to the proposed Merger of C-Cube and DiviCom. The Merger is  subject
to  stockholder and regulatory approval and  other conditions. The unaudited pro
forma condensed combined balance sheet has been prepared as if the  acquisition,
which  will be accounted for as a purchase of DiviCom by C-Cube, was consummated
as of  June  30,  1996. Such  pro  forma  balance sheet  combines  C-Cube's  and
DiviCom's balance sheets as of that date.
    
 
   
    The aggregate net purchase price of $133.9 million has been calculated based
on  the assumption that C-Cube's stock price is $25.75 (closing price as of July
22, 1996) and together with the fair  value of the liabilities assumed has  been
allocated  to the  DiviCom assets acquired.  Included in the  pro forma purchase
price are cash of  $66.2 million plus  the fair value  of the approximately  2.3
million  shares of C-Cube  to be issued  in exchange for  all of the outstanding
Preferred Stock  and Common  Stock of  DiviCom, the  fair value  of the  assumed
options to acquire DiviCom Common Stock of $7.8 million and the estimated direct
transaction  costs of  $1.3 million. The  DiviCom Common Stock  and options were
valued using a C-Cube  stock price of  $25.75 per share.  The allocation of  the
purchase  price was based  upon a preliminary independent  appraisal of the fair
value of the assets acquired  and liabilities assumed. Such appraisal  allocated
$116.8  million  to purchased  technology, $105.4  million of  which represented
in-process research and development, and $3.6 million to goodwill.
    
 
   
    The unaudited pro forma condensed combined statements of operations for  the
year  ended December 31,  1995 and for the  six months ended  June 30, 1996 give
effect to  the  proposed merger  as  if the  acquisition  was completed  at  the
beginning  of the year and six month period, respectively, and combines C-Cube's
and  DiviCom's  statements  of  operations  for  each  of  those  periods.  Such
statements  do not include the effect  of the $105.4 million nonrecurring charge
for in-process  research  and development  that  has not  reached  technological
feasibility  and does not have alternative  future uses. However such statements
do reflect adjustments for  the elimination of  transactions between C-Cube  and
DiviCom,  amortization  of  purchased  technology  and  goodwill,  adjustment of
interest income to effect  cash used in the  transaction and related income  tax
effects.
    
 
    This method of combining historical financial statements for the preparation
of  the pro forma condensed combined statements is for presentation only. Actual
statements of operations of the companies will be combined from the closing date
of the acquisition  with no  retroactive restatements. The  unaudited pro  forma
condensed  combined financial statements are  provided for illustrative purposes
only and are not  necessarily indicative of the  combined financial position  or
combined  results of  operations that  would have  been reported  had the Merger
occurred on  the  dates indicated,  nor  do they  represent  a forecast  of  the
combined  financial position or results of operations for any future period. The
unaudited pro forma condensed  combined financial statements  should be read  in
conjunction  with the historical financial statements and accompanying notes for
C-Cube and DiviCom.

    The  allocation of the  purchase price among  identifiable intangible assets
was based on  a preliminary  independent appraisal of  the fair  value of  those
assets. Such appraisal allocated $105.4 million to purchased in-process research
and  development.  The $105.4  million will  be expensed  in the  third calendar
quarter upon  closing  as  the  technology has  not  yet  reached  technological
feasibility  and does not have alternative  future uses. The unaudited pro forma
condensed combined statements of operations do not include this one-time  charge
for  purchased in-process  technology as  it represents  a material nonrecurring
charge in accordance with the rules  for the preparation of pro forma  financial
statements.
    
 
NOTE 2 -- PRO FORMA ADJUSTMENTS
    The  following pro  forma adjustments  have been  made to  the unaudited pro
forma condensed combined financial statements:
 
    (a) Eliminate intercompany sales, cost of sales and profit in inventory.
 
    (b) Reflects  the  value of  C-Cube  cash and  stock  issued to  effect  the
transaction and the fair value of options assumed by C-Cube.
 
    (c)  Reflects elimination  of DiviCom Common  Stock and  Preferred Stock and
shareholders' deficit.
 
    (d) Reflects allocation of purchase price to existing technology.
 
    (e) Reflects one-time charge for purchased in-process technology.
 
   
    (f) Reflects amortization  on a  straight-line basis  of purchased  existing
technology and goodwill over five and ten years, respectively.
    
 
    (g) Reflects accrual of direct transaction costs.
 
   
    (h)  Reflects the  issuance of  2,386,443 shares  of C-Cube  Common Stock to
effect the transaction and  the dilutive effects of  options to acquire  293,969
shares  of  C-Cube Common  Stock which  represent  the unvested  DiviCom options
assumed by C-Cube.
    
 
   
    (i) Reflects the  loss of interest  income due  to the cash  portion of  the
purchase price.
    
 
   
    (j)  Reflects the effect of the above adjustments on income tax expense. The
differences  between the actual and pro forma effective income tax rates are due
to the  tax accounting  for the  purchased technology  and due  to the  loss  of
interest income due to the cash portion of the purchase price.
    
 
    The  deferred tax  assets recorded  by DiviCom  are included  in the current
assets assumed.

                         INFORMATION CONCERNING C-CUBE
 
THE COMPANY
 
    C-Cube Microsystems Inc. (referred to herein as "C-Cube" or the  "Company"),
established  as a California corporation in  1988 and reincorporated in Delaware
in 1994, is a leading  provider of powerful, highly integrated,  standards-based
digital  video compression solutions. The  Company's innovative encoder, decoder
and codec products enable high quality video to be provided cost-effectively  by
a  broad range  of end  user systems.  Digital video  compression technology has
enabled the development of a significant number of new or enhanced  applications
in the consumer electronics, computer and communications markets including video
compact  disc  ("Video CD")  players, desktop  video production  systems, Direct
Broadcast Satellite  ("DBS") systems,  wireless  cable systems  and  distributed
video networks.
 
BACKGROUND
 
    Since  the  1930s,  video images  have  been transmitted  and  stored almost
exclusively using  analog formats.  Digital video  provides several  fundamental
benefits   over  analog  video.  Unlike  analog  video,  digital  video  can  be
compressed, providing significant storage and transmission efficiencies and  can
be  transmitted and  reproduced without  perceptible image  degradation. Digital
formats also  provide users  with the  benefits of  random access  and  superior
editing capabilities. In the 1980s, the benefits of digital formats led the U.S.
consumer  audio industry to convert from  analog long playing records to digital
CDs, resulting in growth in the market for CD players. In the 1990s, the ongoing
evolution from  analog to  digital is  transforming the  way in  which video  is
produced, stored, transmitted and viewed.
 
    A  significant barrier to the greater market acceptance of digital video has
been the  large volume  of data  required to  represent images  and video  in  a
digital  format, making  storage or  transmission economically  impractical. For
example, storage of  an hour  long video  program in  uncompressed digital  form
would  require  well  over  100 CD-ROMs.  Through  emerging  digital compression
techniques, a substantial number of the redundancies inherent in video data  can
be  detected and eliminated,  significantly reducing the  overall amount of data
which needs to  be retained,  without affecting perceived  image quality.  These
compression techniques allow the same hour long video program which required 100
CD-ROMs  for storage  in uncompressed  format to be  stored on  a single CD-ROM.
Similarly,  a  single  uncompressed  digital  video  program  requires  as  much
bandwidth  for effective  transmission as  50 compressed  video programs, making
uncompressed digital video impractical for markets such as broadcast and  cable.
As  a  result  of  these  limitations, C-Cube  believes  that  the  emergence of
cost-effective and practical  video compression  technology is  critical to  the
development of mass market digital video applications.
 
    Cost-effective  video compression solutions are  now becoming available, and
the benefits  provided  by the  combination  of digital  video  and  compression
technology are enabling the deployment of a large number of new applications and
improving   or   expanding   existing  applications.   Existing   and  potential
applications in the  consumer electronics, communications  and computer  markets
include  Video  CD  players,  digital  video  disk  players,  video conferencing
equipment, video editing  systems, and video  networks, including DBS,  wireless
cable and switched digital systems.
 
    Market  development  for  C-Cube's new  and  expanded  applications requires
communication of  shared  content among  various  products and  across  multiple
industries.   This   interoperability  requires   the  widespread   adoption  of
international compression  standards. In  response to  the need  for  standards,
industry leaders in consumer electronics, computers and communications including
AT&T,  IBM, JVC,  Matsushita, NTT, Philips,  Scientific Atlanta  and Sony joined
together with  C-Cube  in various  committees  sanctioned by  the  International
Standards  Organization (the "ISO")  to define standards  for the compression of
still  images  and  digital  video   for  consumer  electronics  and   broadcast
industries.  The first standard ISO adopted  was a recommendation from the Joint
Photographic Experts  Group  ("JPEG") committee  for  the compression  of  still
images.  C-Cube  believes that  in 1990  it introduced  the first  product which
complied   with    the   JPEG    standard.   The    Moving   Pictures    Experts
 
                                       53
<PAGE>
Group ("MPEG") committee made a recommendation for a standard for compression of
audio  and video to CD-ROM,  which was subsequently adopted  by the ISO, and the
first products complying with the MPEG  1 standard were introduced by C-Cube  in
1991.  MPEG 2, a compression standard used for audio and video broadcast systems
and high density disk players, was recommended by the MPEG committee and adopted
by the ISO in 1994, with initial compliant products introduced by C-Cube earlier
the same year. These ISO standards specify a data format or syntax in which  the
compressed  data  stream must  be presented  in order  to enable  equipment from
multiple vendors to be tied together into a single system that can transmit  and
display  image or  video content  in a  common format.  These standards  do not,
however, specify  the  actual compression  methodology  and, therefore,  do  not
determine   image  quality  or  compression   efficiency.  For  example,  poorly
compressed data  may  comply  with  the relevant  standard  but  contain  visual
artifacts such as blocking, ringing, pixelation and blurring which may result in
poor  image quality or loss  in efficiency, costing capacity  or play time. As a
result, there can be  significant differences in  overall image quality  between
two  solutions based on  the same standard.  Therefore, system manufacturers can
differentiate their products by  the quality of  the compression solution  which
they select.
 
    Applications  utilizing  compressed  digital video  require  an  encoder for
compression  and  a  decoder  for   decompression.  Encoding,  the  process   of
compressing  digital images  using complex mathematical  algorithms to eliminate
redundant information, determines the potential  quality of the resulting  image
and   the   achievable  degree   of  compression.   Decoding,  the   process  of
reconstructing compressed video,  restores a compressed  digital bitstream  back
into  an  uncompressed  and  viewable format.  The  design  and  architecture of
encoders and decoders  are extremely complex,  presenting significant  technical
challenges.
 
    In  the  past,  as  system  vendors  sought  compression  solutions, several
problems emerged. First, the  cost and complexity of  encoding and decoding  and
the  time required to compress digital video were significant limitations on the
use of digital compression. The implementation of the encoding process  required
multiple  circuit boards containing hundreds of expensive discrete digital logic
devices. The expense, power requirements and physical size of such systems  made
encoding  impractical  for  most  applications.  Many  of  these  solutions also
generally required 10 to more than 100 hours to compress a single hour of video,
eliminating their usefulness in applications where significant time delay cannot
be tolerated such as in news or sports broadcasting. The complexity in designing
decoders results from the need for decoders to be highly integrated to meet  the
demand  for low system cost and to be compatible with all applicable compression
standards in  order to  ensure interoperability  among products  from  different
system manufacturers.
 
    In the past, most compression solutions have been hard-wired implementations
developed for a single application which could not be optimized for use in other
applications.  In addition, the cost, size, image quality, compression ratio and
architectural requirements vary widely among system manufacturers. These factors
have made  economies  of  scale  and associated  cost  reductions  difficult  to
achieve. In addition, the limited programmability of such systems has restricted
their  ability to take advantage of improvements in algorithms or to be modified
to address  changes  in  standards  or new  applications.  As  a  result,  these
solutions  have not fully  addressed the needs of  system manufacturers to bring
new  applications  to  market  quickly  or  to  differentiate  their   products.
Furthermore,  the rapid  pace of change  in digital  compression technology, the
ongoing  implementation  of  standards  and  the  continuing  emergence  of  new
applications  necessitate that  emerging compression  technology be  flexible in
order to respond to changing market requirements.
 
MARKETS AND APPLICATIONS
 
    Products enabled by digital video compression technology can be divided into
three broad markets: consumer electronics, communications and computers.

CONSUMER ELECTRONICS
 
    Using MPEG, video can be distributed on the same 5-inch (12 cm) CDs that are
commonly used for  audio. Potential  future applications  for video  compression
technology in the consumer electronics market include the new digital video disk
(DVD)  formats currently being  finalized, digital video  camcorders and digital
video cassette machines.
 
    VIDEO CD PLAYERS.  A Video CD  player is essentially a CD audio player  with
an  MPEG 1 decoder and  a video output. Adding  this functionality increases the
retail price  of a  typical CD  audio player  by $100  to $200  and gives  these
machines  the ability to play movies, music  videos and other titles from MPEG 1
encoded CDs. The physical Video CD disk format is identical to a standard 12  cm
audio  CD and is  limited to 72  minutes play time  with video quality generally
perceived to be  comparable to  an analog VHS  tape. Several  thousand Video  CD
titles  are now available,  including movies, music  videos, and karaoke titles.
China, Japan, Korea,  Taiwan and  other Asian  countries are  known markets  for
Video CDs.
 
    DIGITAL  VIDEO DISK ("DVD") PLAYERS.  Unlike  the Video CD standard which is
an adaptation of the audio CD, next generation Digital Video Disks have recently
been defined specifically for the very  high quality playback of feature  length
movies.  This new format, which is  not yet commercially available, provides 135
minutes average  play time  (270 minutes  for  a double-sided  disk) on  a  high
density  CD-ROM at four times  the image resolution of  a standard Video CD. The
Company believes that this format, which uses MPEG 2 variable bit rate  encoding
and playback, will achieve widespread use in the United States, Europe and Asia.
 
    CONSUMER DIGITAL VIDEO CAMERAS.  Digital video cameras (camcorders) designed
as an alternative to today's analog-based home equipment could potentially offer
advantages  in areas such as image quality, cost, size and interoperability with
other digital  home consumer  appliances such  a DVD  players and  home  editing
equipment. The first tape-based, consumer-grade products using DCT-based formats
called  DV and DVCpro were recently  introduced by companies including Sony, JVC
and Matsushita.  Other formats  which support  recordable disk-based  media  are
currently  being defined.  C-Cube does  not currently  offer products supporting
these formats but may choose to do so in the future.
 
COMMUNICATIONS
 
    Digital video  compression has  the  potential to  enable  a number  of  new
applications  and capabilities in the communications market, including expanding
the  capacity  and  services  of  DBS  systems,  wireless  cable  and  telephone
distribution systems.
 
    DIRECT  BROADCAST SATELLITE  ("DBS") NETWORKS.   By  combining digital video
compression technology with high-power Ku-band satellites, DBS systems have  the
potential  to broadcast over  150 channels directly to  an 18-inch dish antenna.
The increased channel capacity could be used for new services such as near video
on demand, movie  delivery, pay-per-view  and programming  directed to  specific
segments  of  the viewing  audience. Furthermore,  in these  new DBS  systems, a
single satellite can cover a geographical area the size of the contiguous United
States, making reception  possible throughout  rural areas.  DirecTV, the  first
U.S.  deployment of a digital DBS system,  was been introduced by Hughes in 1994
using the Company's encoder products.
 
    MULTICHANNEL MULTIPOINT DISTRIBUTION SERVICE ("MMDS").  MMDS, more  commonly
referred to as wireless cable, is a relatively new method for distributing video
programming.  The service relies  on super high  frequencies ("SHF") to transmit
over the air instead of through overhead or underground wires, requiring a small
receiving antenna to be placed in each  home. It is initially being deployed  in
areas  where there may not  be an existing cable system  or as an alternative to
existing cable  services  in high-density  urban  centers. The  use  of  digital
compression and modulation in MMDS systems provides increased signal range, more
channels and higher reliability than that of older analog MMDS systems.
 
                                       55
<PAGE>
    SWITCHED  DIGITAL NETWORKS.  A number of  new systems are in development and
are expected to  allow telephone  companies to deliver  new services,  including
digital  video, to the  home. These include audio  and video encoders, transport
multiplexers and  sophisticated modulation  technologies to  provide video  over
twisted  pair copper  phone lines  (ADSL), fiber to  the curb  (FTTC) and hybrid
fiber  coax   (HFC)   networks.   Since  telephone   networks   are   inherently
bidirectional,  these new systems  have the potential to  allow for such two-way
services as video on demand, videophones  and interactive services such as  home
shopping.  Each of these systems would typically require a settop decoder in the
home to decode the transmitted  digital signal. IBM, DiviCom, Compression  Labs,
Apple  and  Scientific Atlanta  are providing  equipment which  incorporates the
Company's encoder and decoder products for use in trials and deployments.
 
    AD INSERTION EQUIPMENT.   Ad insertion  equipment enables local  advertising
and program segments to be compressed for storage and retrieval by cable systems
and  local television  stations using high  capacity random  access disks. These
digital-based systems are typically more reliable and cost effective than  older
systems  which were based  on racks of  analog tapes. The  Company's encoder and
decoder products are being incorporated into ad insertion products in the  early
stages  of deployment by  Scientific Atlanta, Digital  Equipment Corporation and
Optibase.
 
    VIDEO CONFERENCING EQUIPMENT.  Standards for high quality video conferencing
such as H.320 and "low delay" MPEG  have met with limited acceptance due to  the
lack  of  appropriate high  speed  digital switched  services  such as  ISDN. As
digital video  networks  become  increasingly available,  the  market  for  such
products  could represent a significant  opportunity. Video conferencing systems
require both an encoder and decoder as well as an appropriate network interface.
 
COMPUTER
 
    Digital video compression technology is currently being used for a number of
computer applications including add-in  cards for games  and Video CD  playback,
content  encoding equipment, non-linear video editing products and desktop video
conferencing systems.
 
    ADD-IN CARDS FOR GAMES AND VIDEO CD PLAYBACK.  Low cost, MPEG 1-based  video
compression  solutions  can substantially  improve  the quality  of  video games
played on a desktop computer. Consequently, support for MPEG 1 video is  growing
among  operating  system providers,  with  both Apple  and  Microsoft announcing
support for MPEG 1. Boards have  been introduced by several companies which  use
C-Cube  MPEG 1 decoders. However, more powerful  CPUs can decode MPEG 1 video in
software and as a result the  Company anticipates that the market for  dedicated
decoding hardware will decrease over time.
 
    ADD-IN  CARDS  FOR  DVD PLAYBACK    The  newly defined  DVD  is  a potential
high-density media format with over seven  times the data storage capacity of  a
standard  CD-ROM. So called Super Density  ROM ("SD-ROM") drives are expected to
replace high-speed CD-ROM  drives as  standard PC peripherals  starting in  late
1996  or early  in 1997. The  addition of an  add-in card which  provides MPEG 2
video decode, Dolby AC3 audio decode and other DVD-specific functions will allow
these drives to play back disks with  material encoded in the DVD, Video CD  and
other video formats. However, it is anticipated that over time, CPUs will become
powerful enough to decode MPEG 2 video in software.
 
    CONTENT  ENCODING  EQUIPMENT.    Interactive  game  consoles  and MPEG-based
hardware and software playback solutions for desktop computers, content To  keep
pace  with the  growth in  Video CD  player markets,  interactive game consoles,
MPEG-based hardware  and  software  playback solutions  for  desktop  computers,
content  providers must efficiently and  cost-effectively compress video content
into MPEG 1 syntax. For example, to support the sales of video karaoke  systems,
thousands  of  titles  must be  compressed  into MPEG  syntax.  This compression
capability is also needed to prepare  digital video for video games,  multimedia
presentations  and storage for  video on demand  services. Several manufacturers
have introduced MPEG 1 content encoding equipment in the form of PC or Macintosh
add-in boards or complete systems based on C-Cube solutions. As DVD formats gain
wider useage, it is anticipated that  desktop encoder solutions for MPEG 2  will
also become available.
 
                                       56

    VIDEO  EDITING  SYSTEMS.    Non-linear  video  editing  is  a computer-based
authoring application that allows editors to quickly and flexibly cut and  paste
video  sequences, reducing the  time and cost of  video post production. Several
companies utilize the Company's products in their professional editing  systems.
In  the future, lower price points and  user interfaces targeted toward home use
may open  up  a  new  market  for editing  equipment.  To  date  most  of  these
applications  have been  JPEG based but  C-Cube recently  introduced the CLM4100
family which supports MPEG-based editing.
 
DEPENDENCE ON EMERGING MARKETS
 
    To date, C-Cube has derived substantially  all of its product revenues  from
sales  of products for  linear video playback (E.G.  movies) and karaoke, direct
broadcast satellite applications and  computer add-in cards,  and from sales  of
products  for development,  trials and early  deployment of  broadcast and other
applications that are not  yet commercially available or  are not yet in  volume
production.  The  Company expects  that Video  CD  and digital  video networking
applications will  continue to  account for  a significant  portion of  C-Cube's
revenues  for the near  future. Over the  longer term, the  Company's ability to
generate increased  revenues  will  be  dependent  on  the  development  of  new
opportunities   for  compressed  digital  video  in  the  consumer  electronics,
communications and  computer markets.  The potential  size of  these new  market
opportunities  and the timing  of their development  is uncertain. Substantially
all of the growth in the sales  of C-Cube's decoder products over the last  year
has  occurred in the  Asia-Pacific region. There  can be no  assurance that such
growth will continue  or that other  markets for C-Cube's  product will  emerge.
Further,  C-Cube's  success  in such  markets  will depend  upon  whether system
manufacturers select the  Company's products for  incorporation into the  system
manufacturers'  products, and upon the successful introduction of such products.
There can be no  assurance that demand  for Video CD  players or other  existing
applications  will be sustained or that new  markets will develop as expected by
the Company, or at all, or that system manufacturers developing products for any
such markets  will  design C-Cube's  products  into their  system  products  and
successfully  introduce such  system products. The  failure of  existing and new
markets to develop as  expected by the  Company or to  be receptive to  C-Cube's
products  would have  a material  adverse effect  on the  Company's business and
results of operations.
 
    The emergence  of markets  for certain  digital video  applications will  be
affected by a variety of factors beyond C-Cube's control. In particular, certain
sectors of the communications market will require the development and deployment
of  an extensive  and expensive communications  infrastructure. There  can be no
assurance that communications  providers will make  the necessary investment  in
such  infrastructure or that the creation of this infrastructure will occur in a
timely manner.  In  addition, the  deployment  of such  infrastructure  will  be
subject to governmental regulatory policies, taxes and tariffs. For example, the
U.S.  Federal Communications  Commission currently  restricts the  number of new
frequencies available for  deployment of new  digital video broadcast  networks,
such  as wireless cable. In addition,  other countries have similar governmental
restrictions. The  development of  such markets  could be  delayed or  otherwise
adversely  affected  by new  governmental regulations  or  changes in  taxes, or
tariffs, or by the failure of  government agencies to adopt changes to  existing
regulations  necessary  to  permit new  technologies  to enter  the  market. The
emergence of these and other markets is also dependent in part upon third  party
content providers developing and marketing content for end user products such as
Video  CD  and DVD  players, interactive  game  consoles, desktop  computers and
settop decoders in a format compatible with the Company's products. There can be
no assurance that these third parties will develop and introduce such content in
a timely fashion, or at all, or that other factors beyond C-Cube's control  will
not adversely affect the development of the digital video applications for which
the Company's products are developed.

    The CL480PC is a microcode-based variant of the CL480VCD, specially intended
for the efficient playback of MPEG 1 titles on the PC. Features contained in the
product  allow it to interface  easily to ISA and PCI  busses as well as popular
scaler/overlay and graphics chips. The lower power requirement of the CL480PC is
well-suited for power sensitive applications  such as notebook computers,  Green
PCs and PCMCIA add-in cards.
 
    CL550 AND CL560 ADVANCED JPEG CODECS
 
    The  CL550 was the first commercially  available codec implementing the JPEG
image compression standard. The  CL550 is highly  integrated and compresses  and
decompresses  high resolution still images  as well as quarter-screen resolution
video at 30 frames per second. The CL550 is used in a variety of products  where
a  low-cost codec is required, including digital cameras, security and LAN-based
video conferencing. The CL560  is a second  generation product which  compresses
and  decompresses video at  full broadcast resolution  and is being incorporated
into digital  video editing  systems  and designed  into color  laser  printers,
facsimiles and copiers.
 
    MVM121 AND MVP131 MULTIMEDIA VIDEO PROCESSORS
 
    The  MVM121 and MVP131 are high-quality scaler/overlay chips that were added
to the C-Cube product line with  the acquisition of Media Computer  Technologies
("MCT")  in November 1995.  These chips allow  the integration of  a video input
from an MPEG decoder, NTSC decoder, TV tuner or other source into ISA-based PCs.
The resultant video  can then be  placed into  a window (overlayed)  on the  VGA
screen and optionally "scaled" in both the horizontal and vertical directions.
 
    CLM4100 MULTISTANDARD CODEC
 
    The CLM4100 provides the capabilities of capturing quarter-screen resolution
video  in real time and storing it to  disk. The user can then edit the material
and once complete,  recode into full  MPEG format at  only slightly slower  than
real  time.  The  Company  believes  that  this  single  chip  solution provides
affordable  MPEG  1  encoding  solutions  for  applications  such  as  Video  CD
production,  video editing  for desktop computers  and high  quality encoding of
video for the Internet.
 
REFERENCE DESIGNS AND DEMONSTRATION SYSTEMS
 
    In addition to its encoder, decoder  and codec VLSI products, C-Cube  offers
board   and  system-level  products   which  serve  as   reference  designs  and
demonstration systems  for  C-Cube  customers that  wish  to  bring  stand-alone
products  into production  quickly or  plan to  incorporate C-Cube's compression
 
                                       60
<PAGE>
solutions in their own products. C-Cube believes these products promote the  use
of  C-Cube's  compression  solutions by  assisting  customers in  the  design of
systems and by reducing the customer's time to market.
 
    REFERENCE  DESIGNS.    For   the  Video  CD   market,  C-Cube  offers   full
manufacturing kits which include all the information required for a manufacturer
to  immediately begin  production of  a CL480  Family-based design  with minimal
engineering required. These kits are designed to allow customers their choice of
several popular CD front-ends, including CD drives and system  microcontrollers.
In  addition, C-Cube offers boards that plug directly into an audio CD player to
upgrade its functionality to include Video CD playback.
 
    For other products, C-Cube  offers reference designs  which are intended  to
give   customers  sufficient  information  such  that  they  can  design  C-Cube
components into their own  system-level solutions. Generally,  these are ISA  or
PCI add-in cards together with software drivers and applications.
 
    C-Cube  believes  that such  manufacturing  kits and  reference  designs are
important because they allow customers to bring C-Cube products into  production
in  a shorter  time and with  less effort  than would otherwise  be possible. In
addition, C-Cube  believes  that the  application  knowledge gained  during  the
development  of these designs  is directly applicable  toward the development of
new, more highly integrated products.
 
    DEMONSTRATION SYSTEMS PRODUCTS.  The  MPEG Encoder Development Station is  a
real  time consumer and broadcast  resolution MPEG 1 and  MPEG 2 video and audio
encoder system  that  is  based  on  the  Company's  VideoRISC  processor.  This
desk-side  system incorporates a SPARC  microprocessor-based board together with
four C-Cube designed boards  for video capture,  video encoding, audio  encoding
and  compressed bitstream transmission. It is designed as a prototyping tool for
customers developing MPEG-based systems. The  Development Station has also  been
used  by  certain  customers to  encode  music  videos, karaoke  and  movies for
distribution on Video CD or via video on demand systems.
 
CHANGING PRODUCT MIX; INCREASING DEPENDENCE ON DECODER PRODUCTS
 
    C-Cube anticipates  that overall  product gross  margins may  decrease as  a
result of a number of factors, including a change in product mix to lower margin
CL480  Family products and anticipated declines in the average selling price for
these products over time. While C-Cube offers a number of products for a variety
of applications, beginning in the second quarter of 1995, sales of the Company's
CL480 Family  have represented  an increasingly  significant percentage  of  the
Company's  total net  revenues and accounted  for a substantial  majority in the
growth of the Company's  total net revenues. The  Company expects that  revenues
from  its CL480  Family will  account for a  significant portion  of its product
revenues in 1996. The Company derives  lower product gross margin from sales  of
the CL480 Family than from sales of its encoder products. Therefore, as revenues
from  sales of the  CL480 Family increase  as a percentage  of the Company's net
revenue, the Company  may experience an  adverse effect on  its overall  product
gross  margins. In  addition, over time,  C-Cube expects  that price competition
will result in declining average selling  prices for these products. C-Cube  may
not  be  able to  continue  to reduce  costs  associated with  the  CL480 Family
sufficiently to  offset the  adverse  effect on  overall product  gross  margins
caused  by the increasing  dependence on the CL480  Family. Although the Company
has implemented several  programs to  further reduce costs  associated with  the
CL480  Family, in the event that increases in unit sales and other manufacturing
efficiencies of the CL480 Family do not offset decreasing prices in the  future,
the  Company's  business  and  results of  operations  would  be  materially and
adversely affected. Moreover, as C-Cube makes changes to its CL480 Family in  an
effort  to  reduce costs,  its customers  must qualify  each new  silicon and/or
microcode revision.  Delays  in customers'  ability  or willingness  to  qualify
revisions  of the CL480 Family  could result in higher  costs or dislocations in
production and supply, which  could have a material  adverse effect on  C-Cube's
operating  results. The timing  of volume shipments  and the life  cycles of the
Company's products are difficult to predict due in large measure to the emerging
nature of  the markets  for  C-Cube's products,  the  future effect  of  product
enhancements by the Company and its
 
                                       61
<PAGE>
competitors  and  future  competition.  Declines  in  demand  for  the Company's
products, particularly the  CL480 Family,  whether as a  result of  competition,
technological  change  or otherwise,  would have  a  material adverse  effect on
C-Cube's business and results of operations.

    For the  first quarter  of  1996, three  divisions of  Samsung  collectively
accounted  for  22%  of  net  revenues and  sales  to  Kanematsu  Corporation, a
distributor, accounted for 12% of the Company's net revenues. During 1995, three
divisions of Samsung collectively accounted for  14% of net revenues, and  sales
to  Serial Systems, a distributor selling to six customers, accounted for 10% of
the Company's net revenues. There can  be no assurance that such customers  will
continue  to account for  a significant percentage of  the Company's revenues in
the future. The  loss of any  of such  customers could have  a material  adverse
effect on the Company's business and results of operations. During 1994 and 1993
no individual customer represented 10% or more of net revenues.
 
RESEARCH AND DEVELOPMENT
 
   
    C-Cube  believes  that the  continued introduction  of  new products  in its
target markets is essential to its growth. As of June 30, 1996, the Company  had
216  full-time employees engaged  in research and  development. Expenditures for
research and development  for the  first six months  of 1996  and during  fiscal
years  1995, 1994 and 1993 were approximately $16.2 million, $14.3 million, $9.8
million and $7.4 million, respectively.
    
 
    The markets for the Company's products are characterized by rapidly changing
technology and evolving  industry standards. In  addition, markets for  C-Cube's
products  are characterized by intense price competition. As the markets for the
Company's products develop  and competition increases,  C-Cube anticipates  that
product  life cycles  will shorten and  average selling prices  will decline. In
particular, average selling  prices and  product gross  margin for  each of  the
Company's  products will decline as  such products mature and  as per order unit
volumes for such products increase. The Company's operating results will  depend
to a significant extent on its ability to continue to successfully introduce new
products  on a timely basis and to reduce costs of existing products. C-Cube has
recently announced several  new products, including  additional versions of  the
CL480  and next generation MPEG  encoders. There can be  no assurance that these
products will  be  successfully developed  or  will achieve  market  acceptance.
However,  the failure of any of these products to be successfully introduced and
achieve market acceptance could have a material adverse effect on the  Company's
business  and results of operations. The success of new product introductions is
dependent on several factors, including  proper new product definition,  product
cost,  timely completion and introduction of new product designs, quality of new
products,  differentiation  of  new  products   from  those  of  the   Company's
competitors  and market acceptance of C-Cube's and its customers' products. As a
result,  the  Company  believes  that  continued  significant  expenditures  for
research and development will be
 
                                       62
<PAGE>
required  in the future. Because  of the complexity of  its products, C-Cube has
experienced  delays  from  time  to  time  in  completing  the  development  and
introduction  of  new products,  and, as  a result,  has from  time to  time not
achieved the  market  share anticipated  for  such  products. There  can  be  no
assurance  that  such delays  will  not be  encountered  in the  development and
introduction of future products. There can be no assurance that the Company will
successfully identify  new  product  opportunities and  develop  and  bring  new
products  to market in a timely  manner, that products or technologies developed
by others  will  not  render  C-Cube's  products  or  technologies  obsolete  or
noncompetitive,  or that the Company's products will be selected for design into
the products of its targeted customers. The failure of any of the Company's  new
product  development efforts  could have a  material adverse  effect on C-Cube's
business and results of operations.
 
SALES AND MARKETING
 
    C-Cube's sales  and marketing  strategy targets  markets for  which  digital
video  compression is an enabling technology in order to achieve key design wins
with industry leaders as well as early adopters of digital video technology.  To
implement  its strategy, the Company has established  a direct sales force and a
worldwide network  of independent  sales  representatives and  distributors.  In
addition,  C-Cube  has a  team  of application  engineers  deployed both  in the
factory and  the  field who  assist  customers in  incorporating  the  Company's
products.
 
    In  the  United States,  the  Company sells  its  products to  key customers
through its direct sales channel. Sales  to other accounts in the United  States
are  made through independent representatives. The Company records revenues from
product sales to customers at the time of shipment. Generally, the Company  pays
its  independent  sales  representatives  on a  fixed  commission  basis.  As of
December 1995,  C-Cube had  North American  regional sales  offices in  northern
California,  Georgia, Texas  and Quebec and  international sales  offices in the
United Kingdom, China, Korea, Hong Kong, Singapore and Taiwan and is considering
opening additional  offices  in Asia,  Europe  and  the U.S.  In  Japan,  C-Cube
distributes  products through the  direct sales force  of Kubota C-Cube ("KCC").
KCC was formed by the Company and Kubota in 1988 and is owned 65% by C-Cube  and
35%  by Kubota. The primary business of  KCC is the marketing, sales and support
of the Company's products in Japan.
 
    Internationally, the  Company  has  commissioned  sales  representatives  or
distributors  in Australia, Canada, China,  France, Germany, Great Britain, Hong
Kong, India, Italy, Korea, Malaysia, Scandinavia, Singapore, and Taiwan. Certain
of the Company's agreements with its distributors permit limited stock  rotation
and  provide for  price protection. Allowances  for returns  and adjustments are
provided at the  time revenues  from product sales  are recorded  and for  price
protection when the Company reduces its published list prices.
 
INTERNATIONAL BUSINESS ACTIVITIES
 
   
    During  the first six months of 1996  and during fiscal years 1995, 1994 and
1993, international revenues accounted for  approximately 79%, 70%, 38% and  37%
of   the  Company's  net  revenues,   respectively,  and  C-Cube  believes  that
international revenues will continue to account for a significant portion of net
revenues. The  significant increase  in international  revenues in  1995 is  due
primarily  to the increase in the sales of  MPEG 1 decoder products in Asia. The
Company's success will depend in part  upon its ability to manage  international
marketing  and sales  operations and  manufacturing relationships.  In addition,
C-Cube purchases a  substantial portion  of its assembly  services from  foreign
suppliers. C-Cube's international manufacturing and sales are subject to changes
in  foreign  political  and economic  conditions  and to  other  risks including
currency exchange rate fluctuations or export/import controls and changes in tax
laws, tariffs  and  freight  rates.  For  example,  China  and  Taiwan  comprise
substantial  markets for  consumer electronics products  utilizing the Company's
CL480 Family,  such as  Video CD  players. As  a consequence,  any political  or
economic  instability in  such countries  could significantly  reduce demand for
products from certain of  the Company's major customers.  The Company is in  the
process  of  securing  additional  foundry capacity  in  the  Republic  of China
(Taiwan). Consequently, the  Company will be  subject to the  risk of  political
instability  in Taiwan, including but not  limited to the potential for conflict
between Taiwan and the People's
    
 
                                       63
<PAGE>
Republic of China.  In addition, the  Company sells certain  of its products  in
international markets and buys certain products from its foundries in currencies
other  than  the U.S.  dollar,  and the  Company  does not  currently  hedge its
exposure to foreign currency fluctuations.  As a result, currency exchange  rate
fluctuations  could have a material adverse effect on the Company's business and
results of operations. With respect to international sales that are  denominated
in  U.S. dollars, increases in the value  of the U.S. dollar relative to foreign
currencies can  increase  the effective  price  of  and reduce  demand  for  the
Company's  products  relative  to  competitive  products  priced  in  the  local
currency. The United States has considered trade sanctions against Japan and  is
considering  trade sanctions  against China relating  to trade  and human rights
issues. If  trade sanctions  were  imposed, Japan  or  China could  enact  trade
sanctions in response. Because a number of the Company's current and prospective
customers  and suppliers  are located  in Japan  and China,  trade sanctions, if
imposed, could have a material adverse  effect on C-Cube's business and  results
of  operations. Similarly, protectionist trade  legislation in either the United
States or  foreign  countries  could  have a  material  adverse  effect  on  the
Company's ability to manufacture or to sell its products in foreign markets.
 
MANUFACTURING
 
    C-Cube  has chosen  to use  independent silicon  foundries to  fabricate its
integrated circuits, and assembly, test and packaging are subcontracted to third
parties. This  approach enables  the  Company to  concentrate its  resources  on
product design and development, where C-Cube believes it has greater competitive
advantages.  The Company, however, continues to evaluate other sources for wafer
capacity in 1997 and beyond.
 
    The Company's  devices are  currently fabricated  using complementary  metal
oxide semiconductor ("CMOS") process technology with 0.8 micron, 0.65 micron and
0.5   micron  feature  sizes,  using  either   two  or  three  layers  of  metal
interconnect. Certain of C-Cube's  new products are  being prototyped with  0.35
micron  feature  sizes. Certain  products are  received  as fully  assembled and
tested units. For other  products the Company takes  receipt of untested  wafers
and  works  with  subcontract  testing facilities.  Once  the  fully  tested and
accepted wafers are received by C-Cube,  the die are assembled into packages  by
subcontractors,  primarily located in the United States, Japan and Korea. C-Cube
then  performs  final  test  and  quality  assurance  checking  at  its  testing
subcontractor before shipping product to its customers.
 
    The  Company established a  strategic foundry relationship  with TI in 1994,
and TI made an equity  investment of $3.0 million in  C-Cube at the time.  Under
the  TI agreement,  TI received  the right  to manufacture  derivatives based on
C-Cube decoders,  including the  CL450 and  CL9100. C-Cube  has entered  into  a
binding   memorandum  of  understanding   with  AMD  providing   for  a  similar
arrangement. The AMD agreement relates to all C-Cube compression products.  Both
the  TI and the  AMD agreements apply  to current and  future generations of the
products subject to such agreements. Under these agreements, and subject to  the
requirement for product differentiation, TI and AMD may introduce products which
compete  with  existing or  future C-Cube  products.  TI has  introduced certain
products which may  compete with present  or future C-Cube  products in  certain
applications.  AMD is not presently manufacturing  products for C-Cube. In April
1996, TI and C-Cube agreed to  discontinue any additional product or  derivative
product  transfers. Otherwise  the balance  of the  agreement remains  in effect
until its expiration in December 1997. The AMD agreement expires December 2002.
 
    The Company believes that foundry  capacity may become increasingly  limited
over the next several years, resulting in increased prices, increased lead times
and  greater  difficulty in  obtaining adequate  capacity.  Any increase  in the
demand for semiconductor wafers over  currently expected levels, or any  failure
of  foundry capacity in the industry to  grow at anticipated rates would magnify
these shortages. C-Cube's  future operating results  will depend in  substantial
part  on its ability to increase the  capacity available to it from its existing
or new foundries. In  order to secure such  capacity, C-Cube has considered  and
will  continue to consider  various possible transactions,  which could include,
without  limitation,  equity  investments  in,  prepayments  to,  non-refundable
deposits  with or loans to foundries  in exchange for guaranteed capacity, "take
or pay" contracts that commit C-Cube to
 
                                       64
<PAGE>
purchase specified quantities of wafers over extended periods or joint  ventures
or  other partnership  relationships with foundries.  There can  be no assurance
that C-Cube will be able to make any such arrangement in a timely fashion or  at
all,  that C-Cube  will not  require additional issuances  of equity  or debt in
order to raise  capital for  any such arrangements  or that  any such  financing
would  be available to C-Cube on acceptable terms  or at all. If C-Cube were not
able on a timely basis to  obtain additional foundry capacity, its business  and
results of operations would be materially and adversely affected.
 
    C-Cube has entered into an agreement with Matsushita Electronics Corporation
("MEC"), JVC and Sharp whereby they provide assistance in the development of the
CL480  and the CL9100 and their derivatives and provide C-Cube with preferential
access to MEC's  0.5 and  0.35 micron manufacturing  processes. As  part of  the
agreement  C-Cube  provides MEC  the right  to  sell the  CL480 to  its internal
divisions and to a limited group of Video CD manufacturers. MEC's right to  sell
the  CL480 has certain volume limitations and  is subject to royalty payments to
C-Cube.
 
    C-Cube procures its integrated  circuit products from  MEC, TSMC and  Yamaha
Corporation  and is in the process  of qualifying additional foundries including
Samsung Semiconductor  Inc.  This dependence  on  a small  number  of  foundries
subjects  C-Cube to risks  associated with an interruption  in supply from these
foundries. In  connection with  the manufacture  of its  newer products,  C-Cube
needs  to continue  to evaluate and  qualify new foundries  that employ advanced
manufacturing and process  technologies, which  are currently  available from  a
limited  number  of foundries.  For example,  certain of  the new  products that
C-Cube intends to  introduce require  advanced CMOS  processes and  in the  past
C-Cube  has  experienced  increased  costs and  delays  in  connection  with the
qualification of new foundries. There can be no assurance that any delays,  cost
increases  or quality problems resulting from the qualification of new foundries
will not have  a material  adverse effect on  C-Cube's business  and results  of
operations.
 
    C-Cube's  reliance on subcontractors  to manufacture, assemble  and test its
products involves significant  risks, including: reduced  control over  delivery
schedules,  quality assurance, manufacturing yields and cost; the potential lack
of adequate  capacity; and  potential  misappropriation of  C-Cube  intellectual
property.  C-Cube obtains foundry capacity  through forecasts that are generated
in advance  of expected  delivery  dates and  are  binding on  C-Cube.  C-Cube's
ability  to obtain the foundry capacity necessary  to meet the future demand for
its products is based on its ability to accurately forecast such future  demand.
Due  to cyclical limitations  on foundry capacity  in the semiconductor industry
and lengthy order lead times required  by many wafer suppliers, if C-Cube  fails
to accurately forecast such future demand, C-Cube may be unable to timely obtain
an  adequate supply  of wafers necessary  to manufacture the  number of products
required to satisfy  its actual demand.  There can be  no assurance that  C-Cube
will  accurately forecast future  demand for its  products and obtain sufficient
foundry capacity in the  future. C-Cube's obligation  to make binding  forecasts
far  in advance  of delivery subjects  C-Cube to inventory  risks, including the
risk of  obsolescence and  commitments  for surplus  capacity. With  respect  to
C-Cube's  principal foundries, these forecasts are also binding on the foundries
upon  acceptance  by  the  foundry,  subject  to  minor  adjustments.   C-Cube's
subcontractors generally do not have firm supply obligations to C-Cube.
 
    C-Cube  has from  time to time  experienced disruptions  in supply, although
none of those disruptions  have to date  materially adversely affected  results.
There can be no assurance that manufacturing or assembly problems will not occur
in  the future  or that any  such disruptions  will not have  a material adverse
effect upon C-Cube's results of operations.  Further, there can be no  assurance
that  suppliers who have committed to provide product will do so, or that C-Cube
will meet  all  conditions imposed  by  such  suppliers. Failure  to  obtain  an
adequate  supply of products on  a timely basis would  delay product delivery to
C-Cube's customers,  which would  have  a material  adverse effect  on  C-Cube's
business and results of operations. In addition, C-Cube's business could also be
materially  and  adversely  affected  if  the  operations  of  any  supplier are
interrupted for a substantial  period of time,  or if C-Cube  is required, as  a
result  of capacity constraints  in the semiconductor  industry or otherwise, to
increase the proportion of wafers or  finished goods purchased from higher  cost
suppliers in order to obtain adequate product volumes.

    The  markets  into  which C-Cube  sells  its products  are  characterized by
extreme price competition, and C-Cube expects the average selling prices of  its
products  will decrease  over the  life of each  product. In  order to partially
offset declines in the selling price of its products, C-Cube will need to reduce
the cost  of  its  products  by  implementing  cost  reduction  design  changes,
obtaining  costs reductions as and if volumes increase and successfully managing
manufacturing and subcontracting  relationships. Since C-Cube  does not  operate
its  own manufacturing facilities and must  make binding commitments to purchase
products, it may not be  able to reduce its costs  as rapidly as companies  that
operate  their own manufacturing facilities. The failure of C-Cube to design and
introduce lower cost  versions of  C-Cube's products in  a timely  manner or  to
successfully  manage  its  manufacturing  relationships  would  have  a material
adverse effect on C-Cube's business and results of operations.
 
COMPETITION
 
   
    The markets  in which  C-Cube  competes are  intensely competitive  and  are
characterized  by declining average selling  prices and rapid technology change.
C-Cube believes that it competes favorably  in the areas of product  definition,
system  cost, functionality, time-to-market,  reliability and reputation. C-Cube
competes with major  domestic and  international companies, most  of which  have
substantially  greater financial and  other resources than  C-Cube with which to
pursue engineering, manufacturing, marketing and distribution of their products.
Some of these companies own proprietary video compression technology competitive
with C-Cube's  standards-based  systems.  In the  consumer  electronics  market,
principal  competitors  include Philips,  SGS-Thompson,  Oak Technology  and ESS
Technology, Inc.,  as  well  as  several  large,  integrated  Japanese  consumer
electronics companies, such as Sony, Toshiba, NEC, and MEI, which have their own
semiconductor  design  and  manufacturing  capacity.  In  the  computer  market,
principal C-Cube competitors include the increasingly powerful CPUs that are now
available from,  among  others,  Intel  and Motorola,  as  well  as  specialized
companies  such as  Zoran and  8x8, and graphics  chip manufacturers  such as S3
Incorporated and  Trident  Microsystems,  Inc.  In  the  communications  market,
C-Cube's principal competitors include SGS-Thomson, LSI Logic, Texas Instruments
and IBM Microelectronics.
    
 
    Recently,   competition   among   suppliers  of   decoder   chips   for  the
communications  market  has  intensified  significantly.  C-Cube  believes   the
scale-up  from limited trials  to wide deployment of  settop decoders will occur
only gradually over time, if  at all. Therefore, success  in this market may  be
dependent  upon future design  wins rather than  upon design wins  for trials or
early deployment.  IBM and  LSI  Logic have  recently announced  the  commercial
availability  of their own MPEG 2 encoders. C-Cube expects that other companies,
such as  SGS-Thomson  and Mitsubishi,  among  others, will  introduce  competing
encoder  products  in the  near future.  Although the  timing of  the production
availability of such encoders is uncertain, their availability would likely have
an adverse impact on C-Cube's encoder  product revenues and margins. C-Cube  may
also  face  increased  competition in  the  future  from new  entrants  into its
markets.  In  particular,  as  the   markets  for  C-Cube's  products   develop,
competition  from large semiconductor  companies, such as  SGS-Thomson, and from
fabless semiconductor companies may increase significantly. Furthermore, as part
of C-Cube's  foundry relationships,  C-Cube has  granted certain  foundries  the
rights  to develop and manufacture derivative  products based on its technology,
subject to royalty  obligations and  certain limitations,  which may  facilitate
direct  competition from  those larger  semiconductor companies.  The ability of
C-Cube to  compete  successfully  in  the  rapidly  evolving  markets  for  high
performance  video  compression technology  depends on  factors both  within and
outside of its control,  including success in  designing and subcontracting  the
manufacture of new products that implement new technologies, adequate sources of
raw  materials,  protection  of  Company products  by  effective  utilization of
intellectual  property  laws,  product  quality,  reliability,  price  and   the
efficiency  of  production, the  pace  at which  customers  incorporate C-Cube's
integrated circuits into their products or technologies, success of competitors'
products and general economic conditions. There can be no assurance that  C-Cube
will be able to compete successfully in the future.

    A  variety  of  other  approaches to  digital  video  compression  have been
introduced, including wavelets, fractal, proprietary compression algorithms  and
software only solutions, and other companies are designing products around these
or  alternative  approaches.  In  addition,  manufacturers  of  general  purpose
microprocessors,  such  as  Intel  and  graphics  chip  manufacturers  such   as
Chromatics, are positioning their products as offering digital video compression
capability, and there can be no assurance that system manufacturers will not use
such  processors for  video compression applications.  In the event  that any of
these other  approaches,  individually  or  collectively,  are  adopted  in  the
emerging  video compression market on a  widespread basis, C-Cube's business and
results of operations would be materially and adversely affected.
 
INTELLECTUAL PROPERTY AND LICENSES
 
   
    C-Cube attempts to protect its technology through a combination of  patents,
copyrights,   trade  secret  laws,   confidentiality  procedures  and  licensing
arrangements. As of June 30, 1996, C-Cube has 9 issued United States patents and
36 U.S. patent applications pending and has filed corresponding applications  in
certain  foreign jurisdictions. These patents expire  at various times from 2010
to 2013. Notwithstanding its patent position,  C-Cube believes that, in view  of
the  rapid  pace  of technological  change  in the  semiconductor  industry, the
technical experience and creative  skills of its  engineers and other  personnel
are  the  most important  factors in  determining C-Cube's  future technological
success.
    
 
    There can  be  no  assurance  that  patents  will  issue  from  any  pending
applications or that any claims allowed from existing or pending patents will be
sufficiently  broad  to protect  C-Cube's  technology. While  C-Cube  intends to
protect its intellectual property rights  vigorously, there can be no  assurance
that  any  patents  held  by  C-Cube  will  not  be  challenged,  invalidated or
circumvented, or that  the rights  granted thereunder  will provide  competitive
advantages  to C-Cube. Moreover,  while C-Cube holds or  has applied for patents
relating to the design of its products,  C-Cube's products are based in part  on
standards,  including MPEG 1, MPEG 2 and  JPEG, and C-Cube does not hold patents
or other intellectual property rights  for such standards. C-Cube believes  that
there  are outstanding  patents in this  area which  may need to  be licensed by
C-Cube or  DiviCom.  The semiconductor  industry  is characterized  by  frequent
litigation  regarding patent and other intellectual property rights. While there
is currently no pending intellectual property litigation against C-Cube,  C-Cube
receives  from time  to time  notices of  potential infringement  of third party
rights and there can be no assurance  that third parties will not assert  claims
against  C-Cube with  respect to existing  or further products  or that licenses
will be  available  on  reasonable  terms,  or  at  all,  with  respect  to  any
third-party  technology  including third-party  technology  which is  or  may be
embodied in standards. In the event  of litigation to determine the validity  of
any  third-party claims, such litigation could  result in significant expense to
C-Cube and divert the  efforts of C-Cube's  technical and management  personnel,
whether or not such litigation is determined in favor of C-Cube. In the event of
an  adverse  result in  any such  litigation,  C-Cube could  be required  to pay
substantial amounts  in damages  and  to cease  selling the  infringing  product
unless  and  until C-Cube  is able  to develop  non-infringing technology  or to
obtain licenses to the technology which was the subject of the litigation. There
can be no assurance that C-Cube would be successful in such development or  that
such  licenses would  be available,  and any  such development  or license could
require expenditure of substantial time and other resources.
 
    C-Cube has entered into certain  technology exchange agreements with TI  and
AMD.  The purpose of these licenses has, in general, been to exchange certain of
C-Cube's core cells  for preferential  wafer fabrication rights.  To the  extent
C-Cube  develops  products  that  are based  on  or  incorporate  the technology
licensed from TI or AMD, C-Cube will  be obligated to pay royalties on sales  of
such  products.  C-Cube  has  also  entered  into  a  development  and licensing
agreement with MEC.
 
    In  1992,  certain  license  agreements  between  C-Cube,  Kubota  and   KCC
originally  entered into in 1988  were amended to provide  in part that Kubota's
license to technology would be limited  to a perpetual, royalty-free license  to
sell  derivatives of C-Cube's  CL550 product provided  that such derivatives are
not pin-compatible or competitive with C-Cube's or KCC's products. In  addition,
 
                                       67
<PAGE>
Kubota  has a  right to  develop system level  products based  on C-Cube's board
designs provided  those products  are not  competitive with  C-Cube's  products.
Kubota  also has the right to purchase certain products at most favored customer
pricing for use in Kubota's products.
 
    In February 1992, C-Cube entered into  an agreement providing that it  would
deposit  into escrow certain technology relating to the CL450, CL950, and CL4000
to be  released  to  JVC in  the  event  of bankruptcy  or  failure  to  perform
development  obligations. In the event of such release, JVC may manufacture such
products for its  own use, subject  to certain royalties.  In June 1993,  C-Cube
entered into a joint development agreement with JVC regarding the development of
the CL480 pursuant to which JVC paid C-Cube a development fee and which provides
for payment of royalties to JVC based on sales of the product.
 
    In  order  to defray  the cost  of  developing its  products and  to develop
products with specifications meeting  customer requirements, C-Cube  established
development  relationships with  JVC, Philips and  Thomson Consumer Electronics.
Under these arrangements, customers provided C-Cube with significant development
funding and development assistance for the CL450, CL950, CLM4500 and CLM4600. In
addition,  these  customers   participated  with  C-Cube   in  determining   the
specifications  for the performance requirements of  these products. As a result
of these  relationships,  C-Cube believes  it  has  been able  to  more  rapidly
introduce  products meeting the demands of these  as well as other customers for
similar applications.  As  consideration  for development  funding,  C-Cube  has
agreed  to pay  certain royalties  to such  customers while  generally retaining
ownership of such products.
 
EMPLOYEES
 
   
    As of May 31, 1996, C-Cube had approximately 395 employees, 216 of whom  are
engaged  in, or directly support, C-Cube's research and development, 105 of whom
are in sales and marketing, 35 of whom  are in manufacturing and 39 of whom  are
in  administration.  C-Cube's employees  are not  represented by  any collective
bargaining agreement, and C-Cube has  never experienced a work stoppage.  C-Cube
believes its employee relations are good.
    
 
    C-Cube's  future success is  heavily dependent upon its  ability to hire and
retain qualified technical, marketing and management personnel. The loss of  the
services  of  key personnel  could have  a material  adverse effect  on C-Cube's
business. C-Cube has recently added a number of new key people to its management
team and  is currently  seeking certain  additional engineering,  marketing  and
management  personnel. C-Cube's success in the future will depend in part on the
successful assimilation of  such new personnel.  C-Cube also obtains  assistance
from  customers whose engineers  participate in development  programs at C-Cube.
The continuing  availability of  such  support is  dependent  upon a  number  of
factors,  including  relationships  with  customers  and  the  ability  of  such
engineers, many of whom are foreign residents, to obtain immigration visas.  The
competition  for  such  personnel, particularly  for  engineering  personnel, is
intense and the loss of such personnel  could have a material adverse effect  on
C-Cube.
 
   
FACILITIES
    
 
   
    C-Cube's  principal facilities consist of  approximately 149,000 square feet
of space  in three  buildings located  in Milpitas,  California. This  space  is
leased  pursuant to two agreements that expire  on January 1, 1998 and April 14,
2005, respectively. C-Cube believes its existing facilities and other  available
facilities  will be adequate to  meet its requirements for  at least the next 12
months.
    
 
   
LEGAL PROCEEDINGS
    
 
   
    C-Cube is not involved in any material pending legal proceedings but may  be
involved  from time to time  as a plaintiff in  routine litigation incidental to
its business.
    
 
ACQUISITIONS
 
    On November 17,  1995, C-Cube  completed the acquisition  of Media  Computer
Technologies,   Inc.  ("MCT"),  a  privately-held   supplier  of  digital  video
processing and video windowing technology for the personal computer market based
in  Santa   Clara,   CA.  The   primary   motivation  behind   the   acquisition
 
                                       68
<PAGE>
was  to  have MCT  personnel  supplement C-Cube's  capabilities  in the  area of
reference designs, application software and the development of highly integrated
video solutions that optimize C-Cube's existing product lines.

    The market price of C-Cube's Common Stock has fluctuated significantly since
the initial public offering in April 1994. The market price of the Common  Stock
could be subject to significant fluctuations in the future based on factors such
as  announcements  of  new  products by  C-Cube  or  its  competitors, quarterly
fluctuations in  C-Cube's financial  results or  other semiconductor  companies'
financial   results,  changes  in  analysts'  estimates  of  C-Cube's  financial
performance, general conditions in the semiconductor industry and conditions  in
the  financial markets. In addition, the stock market in general has experienced
extreme price  and volume  fluctuations, which  have particularly  affected  the
market  prices  for many  high technology  companies and  which have  often been
unrelated  to  the  operating  performance  of  the  specific  companies.   Many
technology companies, including C-Cube, have recently experienced historic highs
in  the market price of their equity  securities. There can be no assurance that
the market price of  the Common stock will  not decline substantially from  such
historic  highs, or otherwise continue to experience significant fluctuations in
the future.
    
 
   
DIVIDEND POLICY
    
 
   
    C-Cube has never paid cash dividends  on its Common Stock. C-Cube  presently
intends  to retain all cash  for use in the  operation and expansion of C-Cube's
business and does not anticipate paying  any cash dividends in the near  future.
In  addition,  the  Company's  existing  bank  credit  agreement  prohibits  the
declaration or payment of cash dividends on its Common Stock.

    NET REVENUES
    
 
   
    Product  revenues increased 193% to $123.2 million in 1995 compared to $42.0
million in 1994. The  increase in product revenues  was primarily due to  volume
shipments  of  the CL480  and CL450  MPEG  1 decoder  products, C-Cube's  MPEG 2
encoder products and the  CL9100 and CL9110 MPEG  2 decoder products. The  CL480
began shipping at the end of 1994, but began significant volume shipments in the
first  quarter of 1995. The CLM4700 MPEG 2 encoders began volume shipping in the
second half of 1994. The  CL9100 and CL9110 began shipping  at the end of  1994,
but  began  to ship  in  significant volume  in the  second  half of  1995. 1994
revenues increased 106% to $42.0 million compared to $20.4 million in 1993.  The
increase  in 1994 product revenues was  primarily due to volume shipments, which
commenced in the second half  of 1993, of the  CLM4500 and CLM4600 encoders  and
the CL560 codec products and increased unit sales of the CL450 decoder product.
    
 
   
    C-Cube's  revenues from development  contracts decreased to  $1.4 million in
1995 as  compared to  $3.0 million  in  1994 and  $3.3 million  in 1993  due  to
C-Cube's focus on product sales.
    
 
   
    During  1995, three divisions  of Samsung collectively  accounted for 14% of
net revenues  and  sales  to  Serial  Systems,  a  distributor  selling  to  six
customers, accounted for 10% of C-Cube's net revenues. There can be no assurance
that  such customers  will continue to  account for a  significant percentage of
C-Cube's revenues in the future. The loss of any of such customers could have  a
material  adverse effect on C-Cube's business  and results of operations. During
1994 and 1993 no individual customer represented 10% or more of net revenues.
    
 
                                       71
<PAGE>
   
    International revenues accounted for  70%, 38%, and 37%  of net revenues  in
1995,  1994, and 1993,  respectively. The significant  increase in international
revenues is due primarily to volume shipments of the CL480 in Asia for Video  CD
players  in the consumer market. C-Cube sells products and supports customers in
Japan primarily through Kubota  C-Cube, Inc. ("KCC"),  C-Cube's 65% owned  joint
venture with Kubota Corporation. C-Cube expects that international revenues will
continue   to  represent  a  significant   portion  of  net  revenues.  C-Cube's
international  sales  and  manufacturing  are  subject  to  changes  in  foreign
political  and economical conditions and  to other risks, including fluctuations
in foreign  exchange rates,  export/import  controls and  changes in  tax  laws,
tariffs and freight rates.
    
 
   
    PRODUCT GROSS MARGIN
    
 
   
    C-Cube's  product gross  margin percentage decreased  to 51.9%  in 1995 from
53.4% in 1994 primarily due to a  shift in product mix whereby the lower  margin
MPEG  1 and  MPEG 2  decoder products  made up  a larger  portion of  sales. The
decline in product  gross margin  was partially  offset by  cost reductions  and
lower  scrap costs in  1995 as compared  to 1994. C-Cube's  product gross margin
percentage decreased to  53.4% in 1994  from 59.3%  in 1993 primarily  due to  a
shift  in product mix whereby  the lower margin CL450  products made up a larger
portion of sales and a decline in average selling prices. Additionally,  product
gross  margins were reduced by  higher scrap costs in  1994 as compared to 1993.
These factors  were  partially  offset  by  increased  sales  of  higher  margin
products, including the CLM4500 and CLM4600 encoders.
    
 
   
    The  markets  into  which C-Cube  sells  its products  are  characterized by
extreme price competition, and C-Cube expects the average selling prices of  its
products  and the gross margin for such  products will decrease over the life of
each product.  In particular,  C-Cube expects  to experience  significant  price
competition  over  the  next  year  with  respect  to  decoder  products. C-Cube
anticipates that  its product  gross margin  may decrease  due to  a  continuing
change  in product mix  toward lower margin  MPEG 1 decoder  products (CL450 and
CL480) and to decreases in average selling prices of certain products. In  order
to  partially offset  declines in  the average  selling prices  of its products,
C-Cube will need  to reduce  the cost of  its products  through design  changes,
obtaining cost reductions from its manufacturers as and if volumes increase, and
successfully   managing  manufacturing  and   subcontracting  relationships.  In
addition, capacity constraints  in the  semiconductor industry  could result  in
higher costs to C-Cube. The failure of C-Cube to design and introduce lower-cost
versions  of its products  in a timely  manner, to take  advantage of lower-cost
processes, or  to  successfully  manage manufacturing  relations  could  have  a
material adverse effect on C-Cube's business and results of operations.
    
 
   
    RESEARCH AND DEVELOPMENT EXPENSES
    
 
   
    In  1995, research and development expenses, which include development costs
associated with customer development contracts,  were $14.3 million or 11.5%  of
net  revenues, compared to $9.8  million or 21.7% of  net revenues, in 1994. The
increase in research and development expenses  from the prior year is  primarily
related  to an  increase in  employee-related costs  as well  as an  increase in
product start-up costs.  In 1994,  research and development  expenses were  $9.8
million  or 21.7%  of net  revenues, compared  to $7.4  million or  31.0% of net
revenues in 1993. The  increase in research and  development expenses from  1993
reflects  higher staffing levels including  outside consultants. The increase in
research and development expenses reflects C-Cube's continued efforts to develop
and bring  to  market innovative  and  cost-effective digital  video  solutions.
C-Cube  anticipates that  absolute levels  of research  and development expenses
will increase in future periods.
    
 
   
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
    
 
   
    Selling, general and administrative expenses  increased to $19.2 million  or
15.4% of net revenues in 1995 compared to $11.3 million or 25.1% of net revenues
for  1994.  The increase  in  absolute dollars  was  primarily due  to increased
staffing and related expenses, increased commissions on higher sales levels  and
a  higher provision for  doubtful accounts. Selling,  general and administrative
expenses increased to $11.3 million or 25.1% of net revenues in 1994 compared to
$8.2 million or  34.6% of  net revenues  for 1993.  The increase  from 1993  was
primarily  due  to  increased commissions  on  higher  sales levels  as  well as
increased headcount and related expenses, partially offset by a lower  provision
    
 
                                       72
<PAGE>
   
for  doubtful  accounts. The  decrease  in selling,  general  and administrative
expenses as a percentage of net revenues over the past three years is  primarily
due  to the significant  increase in net  revenues over the  same period. C-Cube
expects that absolute  levels of  selling, general  and administrative  expenses
will continue to increase in future periods.
    
 
   
    INTEREST INCOME (EXPENSE)
    
 
   
    Interest  income increased to $3.6 million  in 1995 compared to $1.6 million
in 1994 primarily due to the  significant increase in cash and investments  from
cash  provided by operations  as well as the  proceeds from C-Cube's convertible
subordinated note  offering  in the  fourth  quarter of  1995.  Interest  income
increased to $1.6 million in 1994 compared to $0.3 million in 1993 primarily due
to  the  significant  increase in  cash  and  investments from  the  proceeds of
C-Cube's initial public offering. Interest  expense and other increased to  $1.6
million  in 1995 from $1.0 million in 1994 due primarily to interest paid on the
$86.3 million principal on convertible  subordinated notes issued in the  fourth
quarter  of 1995. Interest expense  and other increased to  $1.0 million in 1994
from $0.6 million in 1993.
    
 
   
    INCOME TAX EXPENSE
    
 
   
    C-Cube's effective tax  rate for  1995 of 16.5%  is lower  than the  federal
statutory  rate  as  C-Cube  has reduced  its  valuation  allowance  against its
deferred tax assets in order to recognize the earned benefit from operating loss
carryforwards. As  the benefits  from operating  loss carryforwards  were  fully
utilized  during  the second  half of  1995, C-Cube  expects that  its effective
income tax rate will increase in 1996.  C-Cube's effective tax rate for 1994  of
1% primarily represents the federal alternative minimum tax rate.

    NET REVENUES
    
 
   
    Product  revenues  in the  second  quarter of  1996  were $73.0  million, an
increase of 247%  from the  corresponding quarter a  year ago.  The increase  in
product  revenues  was  primarily  due  to  significantly  increased  volume  of
shipments for  the  CL480 MPEG  1  system decoder  product,  the CL9100  MPEG  2
    
 
                                       73
<PAGE>
   
video  decoder product, the  MPEG 2 encoder  family of products,  and the CL9110
MPEG 2 transport demultiplexer product. In addition, the CL484VCD advanced  MPEG
1  system decoder was  introduced and began significant  volume shipments in the
first quarter  of  1996. The  increase  in  product revenues  noted  above  were
partially  offset  by  a decline  in  the  CL450 MPEG  1  video  decoder product
shipments.
    
 
   
    The Company's  had no  revenues  from development  contracts in  the  second
quarter of 1996 as compared to $0.6 million in the second quarter of 1995.
    
 
   
    During  the  second  quarter  of  1996, Samsung  accounted  for  17%  of net
revenues, and  sales  to  Kanematsu  Semiconductor  Corporation,  a  distributor
selling to seventeen customers, accounted for 14% of the Company's net revenues.
During the same period last year, no individual customer represented 10% or more
of  net revenues. There can be no assurance that such customers will continue to
account for a significant  percentage of the Company's  revenues in the  future.
The  loss of any of  such customers could have a  material adverse effect on the
Company's business and results of operations.
    
 
   
    International revenues  accounted for  82% of  net revenues  for the  second
quarter, compared to 47% for the same period last year. The significant increase
in  international sales is  primarily due to  volume shipments of  the CL480 and
CL484 MPEG 1 system decoders in Asia for video CD players in the consumer market
and the CL9100  MPEG 2 video  decoder product  and the CL9110  MPEG 2  transport
demultiplexer   product  primarily  for   international  deployments  of  direct
broadcast satellite.  The  Company  expects  that  international  revenues  will
continue   to  represent  a  significant   portion  of  net  revenues.  C-Cube's
international  sales  and  manufacturing  are  subject  to  changes  in  foreign
political  and economic conditions and to  other risks including fluctuations in
foreign exchange rates, export/import controls and changes in tax laws,  tariffs
and  freight rates. For  example, China and  Taiwan comprise substantial markets
for  consumer  electronics  products  utilizing  the  Company's  MPEG  1  system
decoders,  such as Video CD players. As a consequence, any political or economic
instability in such  countries could  significantly reduce  demand for  products
from certain of the Company's major customers.

</TABLE>
    
 
   
    C-Cube's product gross margin  percentage increased to  54.0% in the  second
quarter  of 1996  from 50.2%  in the  prior year  quarter primarily  due to cost
reductions over the same  period, partially offset by  a decline in the  average
selling  prices of several of the Company's products, an increased provision for
inventory reserves  and a  shift in  product  mix to  the lower  margin  decoder
products.
    
 
   
    The  markets  into  which C-Cube  sells  its products  are  characterized by
extreme price competition, and the Company expects the average selling prices of
its products and the gross margin for such products will decrease over the  life
of  each product. In order to partially  offset declines in the selling price of
its  products,  C-Cube  will  need  to  reduce  the  cost  of  its  products  by
implementing cost reduction design changes, obtaining costs reductions as and if
volumes  increase  and  successfully managing  manufacturing  and subcontracting
relationships.  Since  the  Company  does  not  operate  its  own  manufacturing
facilities  and must make long-term binding commitments to purchase products, it
    
 
                                       74
<PAGE>
   
may not be able to reduce its  costs as rapidly as companies that operate  their
own manufacturing facilities. The failure of the Company to design and introduce
lower  cost  versions  of  the  Company's products  in  a  timely  manner  or to
successfully manage  its  manufacturing  relationships  would  have  a  material
adverse effect on C-Cube's business and results of operations.
    
 
   
    RESEARCH AND DEVELOPMENT EXPENSES
    
 
   
    In  the second quarter of 1996,  research and development expenses were $9.4
million, or 13%  of net revenues,  as compared to  $3.0 million, or  14% of  net
revenues,  in the  comparable prior  year period.  The decrease  in research and
development expenses  as a  percent of  net  revenues is  primarily due  to  the
significant  increase  in net  revenues over  the same  period. The  increase in
research and  development  spending from  the  prior year  quarter  reflects  an
increase  in employee-related costs as well  as the Company's continuing efforts
to develop  and bring  to  market innovative  and cost-effective  digital  video
solutions.  The Company expects that absolute levels of research and development
expenses will continue to increase in future periods.
    
 
   
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
    
 
   
    Selling, general and administrative expenses  increased to $8.3 million,  or
11% of net revenues, in the second quarter of 1996, as compared to $4.2 million,
or 20% of net revenues, for the same quarter last year. The decrease in selling,
general  and administrative expenses  as a percent of  net revenues is primarily
due to  the significant  increase in  net  revenues over  the same  period.  The
increase  in  spending  was primarily  due  to increased  headcount  and related
expenses and increased commissions on  higher sales levels. The Company  expects
that  absolute  levels  of  selling, general  and  administrative  expenses will
continue to increase in future periods.
    
 
   
    INTEREST INCOME (EXPENSE)
    
 
   
    Interest income, net of interest expense  decreased to $2.4 million for  the
second  quarter  of  1996 from  $5.3  million  for the  second  quarter  of 1995
primarily due to  interest accrued  for the  Company's convertible  subordinated
notes which were issued in the fourth quarter of 1995. The decline was partially
offset  by  the  increased  interest  income from  the  proceeds  of  a  sale of
convertible subordinated  notes in  November 1995.  See "Liquidity  and  Capital
Resources."
    
 
   
    INCOME TAX EXPENSE
    
 
   
    The Company's effective tax rate for the second quarter of 1996 was 37%. The
Company's  effective tax rate increased  from that of 1995  as the benefits from
operating loss carryforwards were fully utilized.

    NET REVENUES
    
 
   
    Product revenues for  the first  half of 1996  were $140.9  million, a  275%
increase  from $37.5 million in product revenues during the corresponding period
in 1995. The  increase in product  revenues was primarily  due to  significantly
increased  volume of shipments for the CL480  MPEG 1 system decoder product, the
CL9100 MPEG 2 video decoder product, the MPEG 2 encoder family of products,  and
the  CL9110 MPEG  2 transport demultiplexer  product. In  addition, the CL484VCD
advanced MPEG  1 system  decoder  was introduced  and began  significant  volume
shipments  in the first quarter of 1996.  The increase in product revenues noted
above were partially  offset by  a decline  in the  CL450 MPEG  1 video  decoder
product shipments.
    
 
   
    The  Company's revenues from development contracts decreased to $0.2 million
in the first half of 1996 from $1.2 million in the first half of 1995.

    C-Cube's product gross  margin percentage  increased to 53.5%  in the  first
half  of  1995  from  51.3% in  the  prior  year period  primarily  due  to cost
reductions over the same  period, partially offset by  a decline in the  average
selling  prices of several of the Company's products, an increased provision for
inventory reserves  and a  shift in  product  mix to  the lower  margin  decoder
products.

    RESEARCH AND DEVELOPMENT EXPENSES
    
 
   
    In  the first half of 1996, research and development expenses, which include
development costs  associated with  customer development  contracts, were  $16.2
million  or 11%  of net  revenues, as compared  to $5.8  million, or  15% of net
revenues, in the  comparable prior  year period.  The increase  in research  and
development  expenses  from  the  prior  year  period  reflects  an  increase in
employee-related costs as well as an increase in product start-up costs.
    
 
   
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
    
 
   
    Selling, general and administrative expenses increased to $16.1 million,  or
11%  of net revenues in the first half  of 1996, as compared to $8.0 million, or
21% of net revenues for  the same period last  year. The increase was  primarily
due  to  increased  commissions on  higher  sales  levels as  well  as increased
headcount and  related  expenses, partially  offset  by a  lower  provision  for
doubtful accounts.
    
 
   
    INTEREST INCOME (EXPENSE)
    
 
   
    Interest  income net of  interest expense decreased to  $0.7 million for the
first half of 1996 from $1.0 million for the first half of 1995 primarily due to
interest accrued for  the Company's  convertible subordinated  notes which  were
issued  in the fourth quarter  of 1995. The decline  was partially offset by the
increased  interest  income  from  the   proceeds  of  a  sale  of   convertible
subordinated notes in November 1995. See "Liquidity and Capital Resources."
    
 
   
    INCOME TAX EXPENSE
    
 
   
    The  Company's effective tax  rate for the  first half of  1996 was 36%. The
Company's effective tax rate  increased from that of  1995 as the benefits  from
operating loss carryforwards were fully utilized.
    
 
   
FACTORS THAT MAY AFFECT FUTURE RESULTS
    
 
   
    C-Cube's quarterly and annual operating results have been, and will continue
to  be, affected by a wide variety of factors that could have a material adverse
effect on revenues and profitability during any particular period, including the
level of  orders  which are  received  and can  be  shipped in  a  quarter,  the
rescheduling  or cancellation of orders  by its customers, competitive pressures
on selling prices, changes in product or customer mix, availability and cost  of
foundry capacity and raw materials, fluctuations in yield, loss of any strategic
relationships,  C-Cube's ability to introduce new products and technologies on a
timely  basis,  new  product  introductions  by  C-Cube's  competitors,   market
acceptance  of products of both C-Cube and its customers, supply constraints for
other  components   incorporated   into  its   customers'   products,   currency
fluctuations,  and the  level of  expenditures in  research and  development and
sales, general and administrative functions.
    
 
   
    In addition, C-Cube's operating  results are subject  to fluctuation in  the
markets  for  its  customers' products,  particularly  the  consumer electronics
market, which has  been extremely volatile  in the past,  and the broadcast  and
cable  markets, which are in an early stage creating uncertainty with respect to
product volume  and timing.  Furthermore,  to the  extent  C-Cube is  unable  to
fulfill  its customers' purchase orders  on a timely basis,  these orders may be
cancelled due to changes in demand  in the markets for its customers'  products.
Historically,  C-Cube  has generally  recognized  a substantial  portion  of its
product revenues in the last month of a given quarter. A significant portion  of
C-Cube's  expenses is relatively fixed, and  the timing of increases in expenses
is based in large part on C-Cube's forecast of future revenues. As a result,  if
revenues  do not meet C-Cube's expectations, it  may be unable to quickly adjust
expenses to levels appropriate to actual  revenues, which could have a  material
adverse effect on C-Cube's business and results of operations.
    
 
   
    The  growth in revenues and operating income experienced by C-Cube in recent
quarters is not necessarily indicative of  future results. In addition, in  view
of the significant growth in recent years, C-Cube believes that period-to-period
comparisons  of its financial results should not be relied upon as an indication
of future performance. Due  to C-Cube's dependence  on the consumer  electronics
and  home computer markets, the substantial seasonality of sales in such markets
could  impact  C-Cube's  revenues  and  net  income,  with  the  highest  levels
experienced in the third and fourth calendar
    
 
                                       77
<PAGE>
   
quarters  as system manufacturers make purchases  in preparation for the holiday
season, and  relatively less  strong demand  in the  first and  second  calendar
quarters.  C-Cube's significant growth  in prior periods  makes it impossible to
assess the effect  of any such  seasonal trends on  C-Cube's operating  results.
There  can be  no assurance, however,  that C-Cube's operating  results will not
exhibit such seasonal characteristics in the future.
    
 
   
    As a result of the foregoing, C-Cube's operating results and stock price may
be subject to  significant volatility,  particularly on a  quarterly basis.  Any
shortfall  in  net revenues  or net  income from  levels expected  by securities
analysts could have an immediate and  significant adverse effect on the  trading
price of C-Cube's common stock.
    
 
   
    C-Cube  has recently experienced  a period of  significant growth, which has
placed, and could continue  to place, a significant  strain on C-Cube's  limited
personnel  and other resources.  C-Cube's ability to  manage any further growth,
should it  occur,  would  require  significant expansion  of  its  research  and
development  and marketing and sales  capabilities and personnel. In particular,
C-Cube is in the  process of expanding its  sales and marketing organization  to
increase coverage of the United States and the Asia-Pacific region. There can be
no  assurance that C-Cube will be able  to find qualified personnel to fill such
sales and marketing positions or be able to successfully manage a broader  sales
and  marketing organization. In addition, the  sale and distribution of products
to numerous large system manufacturers  in diverse markets and the  requirements
of such manufacturers for design support would also place substantial demands on
C-Cube's  research  and development  and  sales functions.  C-Cube's  ability to
manage any further  growth, should it  occur, would depend  upon its ability  to
manage and potentially expand its foundry relationships. The failure of C-Cube's
management  to effectively expand or manage  these functions consistent with any
growth which may occur could have a material adverse effect on C-Cube's business
and results of operations.
    
 
   
LIQUIDITY AND CAPITAL RESOURCES
AT DECEMBER 31, 1995
    
 
   
    Cash, cash  equivalents  and  short-term  investments  increased  to  $144.1
million at December 31, 1995 from the $43.8 million at the end of 1994 primarily
due  to  the  $83.7  million  net  proceeds  from  the  issuance  of convertible
subordinated notes  in the  fourth  quarter of  1995 (see  Note  2 of  Notes  to
Consolidated  Financial Statements). Working capital increased to $158.6 million
at December 31, 1995 from $48.8 million at the end of 1994.
    
 
   
    C-Cube's operating  activities  provided  cash  of  $30.7  million  in  1995
primarily  from net income and higher  accounts payable and accrued liabilities,
partially offset by an  increase in the accounts  receivable and inventory.  The
increase in receivables from December 31, 1994 reflects the significant increase
in  revenues over the same period. The increase in accounts payable is primarily
due to a significant increase in production activities near the end of 1995.
    
 
   
    C-Cube's investing activities, exclusive of the maturities and purchases  of
short-term  investments of $49.7  million and $29.8  million, respectively, used
cash  of  $12.3  million,  primarily  for  the  acquisition  of  Media  Computer
Technologies, Inc. ("MCT") and capital expenditures.
    
 
   
    Cash  provided by financing activities was  $81.1 million, consisting of the
proceeds of  the  convertible subordinated  note  offering and  sales  of  stock
pursuant to employee stock plans partially offset by payments of debt.
    
 
   
    C-Cube  had an aggregate  outstanding balance of  $1.6 million under capital
lease lines at December  31, 1995. C-Cube's 65%-owned  subsidiary, KCC, has  yen
denominated  credit lines with  a group of Japanese  banks guaranteed by Kubota,
the 35% minority shareholder  of KCC, the outstanding  balance of which was  200
million  yen (or approximately $1.9 million) at December 31, 1995. In the fourth
quarter  of  1995,  C-Cube  and  Kubota  recapitalized  KCC  by  making  capital
contributions  of 162.5 million  yen (or approximately  $1.6 million at December
31, 1995) and  87.5 million yen  (or approximately $.8  million at December  31,
1995), respectively.
    
 
                                       78
<PAGE>
   
AT JUNE 30, 1996
    
 
   
    Cash,  cash equivalents  and short-term  investments were  $142.1 million at
June 30, 1996 as compared to $144.1 million at the end of 1995. Working  capital
decreased  to $143.7 million at June 31, 1996  from $158.6 million at the end of
1995.
    
 
   
    The Company's  operating activities  provided cash  of $7.0  million in  the
first  half  of 1996  primarily  from net  income  and higher  accounts payable,
accrued liabilities and  income taxes  payable, partially offset  by an  advance
payment  for wafer production  capacity and an  increase in accounts receivable,
inventory, deferred taxes  and other  assets. The increase  in receivables  from
December  31, 1995 reflects an increase in  the volume of sales of the Company's
key products. The increase in accounts payable is primarily due to a significant
increase in production activities near the end of the second quarter.
    
 
   
    C-Cube's investing activities, exclusive of the maturities and purchases  of
short-term  investments of $24.3  million and $48.3  million, respectively, used
cash of $9.3 million, primarily for capital expenditures.
    
 
   
    Cash used in financing activities  was $0.1 million, consisting of  payments
of  debt partially offset by  proceeds from sales of  stock pursuant to employee
stock plans.
    
 
   
    C-Cube had an aggregate  outstanding balance of  $1.2 million under  capital
lease  lines at June 30, 1996. The  Company's 65%-owned subsidiary, KCC, has yen
denominated credit lines with a group of Japanese banks. At June 30, 1996  there
were no borrowings under this line.
    
 
   
    In  January 1996,  the Company increased  its available bank  line of credit
from $8.5 million to $20 million. The  line of credit expires November 1,  1996.
The  line is  collateralized by the  Company's receivables,  inventory and fixed
assets. The line of credit agreement  requires the Company, among other  things,
to  maintain  a tangible  net worth  (as defined)  of $140  million, 80%  of its
tangible consolidated  assets  within the  U.S.  parent company,  quarterly  net
income  (no more than one quarterly loss per fiscal year), a quick ratio of 1.75
to 1, and a maximum debt to tangible net worth (as defined) ratio of 0.75 to  1.
In  addition, this agreement prohibits the payment of cash dividends. Borrowings
bear interest at the  bank's prime rate.  At June 30, 1996,  the Company was  in
compliance with these covenants, and there were no borrowings under this line.
    
 
   
    In  the second quarter the Company  expanded and formalized its relationship
with Taiwan Semiconductor Manufacturing Corporation (TSMC) to provide additional
wafer production capacity over  the 1996 to 2001  timeframe. The agreement  with
TSMC  requires C-Cube  to make  two advance  payments totaling  $49 million. The
first advance payment  of $24.5 million  was made  in June 1996,  and the  final
payment  is due June  1997, which is secured  by a promissory  note. At June 30,
1996, $1.4 million of the $49 million production capacity rights is included  in
deferred taxes and other current assets.
    
 
   
    Based  on current  plans and  business conditions,  C-Cube expects  that its
cash, cash  equivalents and  short-term investments  together with  any  amounts
generated  from operations and available borrowings,  if any, will be sufficient
to meet  the  Company's cash  requirements  for at  least  the next  12  months.
However, there can be no assurance that the Company will not be required to seek
other financing sooner or that such financing, if required, will be available on
terms  satisfactory to the Company. In  addition, the Company has considered and
will continue to  consider various  possible transactions  to secure  additional
foundry  capacity, which  could include, without  limitation, equity investments
in, prepayments  to,  deposits  with  or loans  to  foundries  in  exchange  for
guaranteed capacity, "take or pay" contracts that commit the Company to purchase
specified  quantities of wafers over extended periods or joint ventures or other
partnership relationships with foundries.

CERTAIN RELATIONSHIPS AND TRANSACTIONS OF C-CUBE
    
 
   
    During  December 1992, certain agreements  originally entered into in August
1988 between C-Cube  and Kubota Corporation  ("Kubota"), a holder  of record  of
more  than 5%  of outstanding  shares of  C-Cube, were  amended to  provide that
Kubota will continue to guarantee  through March 31, 1996 a  bank debt of up  to
Y700,000,000  of  Kubota C-Cube,  Inc. ("KCC"),  a joint  venture formed  by the
C-Cube and Kubota. Pursuant to a subsequent amendment to such agreements, Kubota
agreed to continue to guarantee decreasing amounts during the following periods:
up to Y450,000,000,  Y250,000,000 and Y125,000,000  following the first,  second
and  third anniversaries  of such closing  of C-Cube's  initial public offering,
respectively, with such guarantee expiring in  its entirety three years and  six
months  after such closing. C-Cube  also agreed to issue  to Kubota a warrant to
acquire up to 350,000 shares of its Common  Stock at a per share price of  $0.70
only  in the event that Kubota is required to make payments under such guarantee
and is not reimbursed by the C-Cube.
    
 
   
    In June 1993, C-Cube granted  an option to Pierre  Lamond to purchase up  to
50,000  shares of its Common  Stock at a price per  share of $1.00, which option
was subsequently exercised. The option was granted in connection with Mr. Lamond
providing certain engineering management services and assistance to C-Cube.  The
shares issued upon exercise of the option vest over a period for four years, and
unvested  shares are  subject to repurchase  by C-Cube at  the original purchase
price in the event of  the termination of Mr.  Lamond's services to C-Cube.  Mr.
Lamond is a general partner of Sequoia Capital. Entities affiliated with Sequoia
Capital hold of record more than 5% of outstanding shares of C-Cube.
    
 
   
    In  payment of  the exercise  price of  options to  purchase C-Cube's Common
Stock exercised in  February 1993  and October 1993  by William  J. O'Meara  and
James  G. Burke, respectively, C-Cube accepted promissory notes from Mr. O'Meara
and Mr. Burke in  the principal amounts of  $525,000 and $70,000,  respectively,
with interest payable at rates of 6.22% and 5.00% per annum, respectively. As of
December 31, 1995, the balances due on such loans were approximately $44,390 and
$17,000,  respectively.  Such loans  are payable  in full  in February  1997 and
October 1997, respectively. Mr. O'Meara is a director of C-Cube and Mr. Burke is
an officer of C-Cube.
    
 
   
    C-Cube granted  a  nonqualified  stock  option to  Donald  T.  Valentine  in
February  1993, but  through an  oversight failed to  deliver the  option to Mr.
Valentine in a timely manner. As a result, Mr. Valentine incurred less favorable
tax consequences when he  exercised the option than  he would have incurred  had
the  option been timely issued by C-Cube and exercised immediately thereafter by
Mr. Valentine. C-Cube, however,  gained from this oversight  by receiving a  tax
benefit.  To  rectify  this matter,  in  June  1994 C-Cube  entered  into  a tax
agreement with Mr. Valentine pursuant to  which C-Cube (i) made payments to  Mr.
Valentine  of $192,267, the  amount necessary to compensate  him for the adverse
tax consequences, (ii) guaranteed  a loan from  a bank to  Mr. Valentine in  the
amount  of  $279,647 and  (iii)  made payments  to  Mr. Valentine  in  an amount
sufficient to compensate Mr. Valentine for the interest thereon. The results  of
this  arrangement have  not adversely  affected C-Cube's  cash flow,  and C-Cube
believes that  the overall  consequences of  this arrangement  to its  financial
performance in any period were not significant.

BACKGROUND
 
    Historically, video  and audio  have  been transmitted  in analog  form  via
terrestrial  broadcast, satellite and  microwave transmissions as  well as cable
distribution  systems.  This   same  information  is   now  increasingly   being
transmitted in digital form. Transmission of information in digital form is more
efficient,  achieves better  quality and is  more reliable  than transmission in
analog form. The greater efficiency of digital transmission is primarily due  to
the fact that the digital information can be compressed by using algorithms that
maintain  perceived visual and  audio quality, while reducing  the volume of the
data transmitted.
 
    Companies engaged in  the business  of transmitting digital  video data  are
increasingly   searching  for  products  and  tools  that  afford  ever  greater
compression capabilities. The  ability to compress  large quantities of  digital
data  is emerging  as a  key competitive factor  for these  companies because it
allows them to deliver  more information to end  users without increasing  their
investment  in additional  transmission media  (E.G., cable,  telephone lines or
satellite transponders).
 
    In order  to  compress,  transmit  and receive  digital  video  data,  these
companies  must acquire, integrate  and use a wide  variety of sophisticated new
system and network technologies. Because these new technologies are diverse  and
complex,  many of these companies can benefit from integration services provided
by companies that are experienced with these technologies.
 
    To meet the  often conflicting goals  of interoperablility, reliability  and
efficiency,  nearly all new systems for broadcasting digital video implement new
standards such  as  MPEG 2,  DVB  and (where  applicable)  ATM. In  some  cases,
companies  that have previously provided proprietary analog-based solutions have
developed their own proprietary digital-based solutions (or created  proprietary
solutions   where  there  are   no  standards,  such   as  conditional  access).
Increasingly, companies that broadcast  video realize that  they need to  foster
interoperability  and  competition among  their equipment  vendors. Accordingly,
adherence to common standards is a key requirement for suppliers in this market.
 
    DiviCom offers open  systems based  on industry standards  that allow  these
companies  to compress, transmit  and receive large  quantities of digital video
information. DiviCom provides  "end-to-end," standards-based  solutions for  its
customers.  This means  that DiviCom's systems  products allow  its customers to
compress information,  scramble  the  transmission and  remultiplex  (I.E.,  add
portions  such as  advertisements as  well as  delete portions),  then assist in
transmitting the  information. When  the  information reaches  its  destination,
DiviCom's  decoder products assist in  receiving, descrambling and decompressing
the information so that the information can be viewed.

BUSINESS MODEL
 
    DiviCom designs, manufactures and sells digital video networking systems, as
well as integration, maintenance and support services. DiviCom also manufactures
complete receiving units referred to as decoders for low-volume professional and
private network applications as  well as license its  settop decoder designs  to
large consumer settop box manufacturers for high volume production.
 
MARKETS AND APPLICATIONS
 
    DiviCom  currently  sells  its  products and  services  into  several market
segments, including direct  broadcast satellite, broadcast  over wireless  cable
systems and wired digital video networks, such as SDV, HFC and twisted pair.
 
    DIRECT BROADCAST SATELLITE
 
    The   first  full-scale  digital  video  transmission  systems  were  direct
broadcast satellites  ("DBS")  (often  called  Direct  to  Home)  networks.  The
advantages  of DBS are  that it provides a  low cost per  home and also requires
little  or  no  investment  or  upgrading  of  infrastructure  (rewiring).   The
disadvantages  are the high initial fixed cost  of launching a satellite as well
as the lack of interactivity and unavailability of local programming content.
 
    WIRELESS CABLE OR MMDS
 
    Multichannel Multipoint Distribution Systems  are beginning conversion  from
analog  to digital at this time. Such  systems are based upon local transmitters
with direct line of  sight transmission to a  small receiving antenna placed  on
each home. MMDS have low fixed costs and a moderate cost per home. MMDS supports
local  content  and has  a  moderate level  of  interactivity, such  as Internet
support.
 
    WIRED DIGITAL VIDEO NETWORKS
 
    Wired digital video networks, which include deployments in architecture such
as SDV,  HFC and  twisted pair  schemes such  as ADSL,  are currently  in  early
trials. Each of these are being evaluated and may be deployed by leading telecom
suppliers  as well  as digital  cable providers.  These services  provide a much
higher level of interactivity  as compared to either  DBS or MMDS including  the
potential for full two-way video communication. However, cost per home is high.
 
    In  addition  to  providing  products  and  services  in  support  of  large
deployments such as DBS, wireless cable and SDV, DiviCom products are used in  a
variety  of other video applications.  Such applications include equipment which
enables digital transmission from remote sites to a studio (contribution),  from
studios to cable head ends (distribution) and the use of digital video and audio
within businesses, educational facilities and institutions (private networks).
 
RELEVANT STANDARDS
 
    DiviCom believes that customers strongly prefer solutions built on standards
in  order to achieve interoperability. DiviCom  focused its efforts on three key
standards: MPEG 2, ATM and DVB.
 
    MPEG 2  is a  standard  for audio  and  video compression  and  multiplexing
developed  under  the  auspices of  the  Moving  Pictures Experts  Group  of the
International Standards Organization.  MPEG 2  was adopted  at an  international
conference  in Singapore in 1994 with 32 nations participating in the definition
of  standards  for  three  elements   of  compression:  video,  audio  and   the
synchronization  of audio  and video. Equipment  must meet the  standards of all
three  elements  in  order  to   be  MPEG  compliant  (International   Standards
Organization (ISO) Document Number IEC 11172).
 
    Asynchronous  Transfer Mode ("ATM")  is a specification  for the routing and
transmission of data  over high-speed switched  digital lines, typically  fiber.
The  protocol  is  being  specified  in  many  switched  digital  video  network
deployments.
 
    DVB is a group of government and industry representatives, based in  Europe,
who  have assembled a specification which is intended to promote standardization
and interoperability among the
 
                                       89
<PAGE>
components required to build digital video networks. The specification calls for
the use of MPEG 2 transport  streams and also specifies modulation, elements  of
access control, on-screen display and other system level requirements.

management and insertion  products. Encoders  compress video  and audio  signals
into  MPEG  2  "transport"  streams  to  be  sent  out  over  various  networks.
Multiplexers provide  for the  manipulation of  compressed audio/video  streams,
including  adding  and  dropping  streams,  ensuring  the  timing  fidelity  and
synchronization  of  streams,  extracting  and  inserting  control  information,
scrambling for conditional access, inserting related and unrelated data streams,
and  monitoring signal fidelity. Management systems  consist of a Simple Network
Management  Protocol  ("SNMP")  based  software  system  which  is  capable   of
configuring   and  monitoring  a  network  of  components  ranging  from  analog
audio/video switching to multiplexing. Insertion products are designed to insert
local and/or  commercial  programming material  for  local distribution  into  a
stream  from a wider  network broadcast. DiviCom's  systems products encompass a
range of  products developed  by  DiviCom as  well  as integration  services  to
combine  these products  with third party  products to  deliver complete digital
video networking systems.
 
    MEDIAVIEW MV20:  DiviCom's MediaView MV20  encoder offers a flexible MPEG  2
compression  system in a very compact form factor. The MediaView MV20 compresses
one video signal and two or more stereo audio channels, and outputs a compressed
transport stream  which  is  fully  compliant  with  the  MPEG  2  international
standards. The MediaView MV20 supports numerous digital and analog audio inputs,
multiple  video  input formats,  data  inputs, multiplexing,  conditional access
support and output formats, including ATM. Due to its plug-and-play flexibility,
the MediaView  MV20 is  suited for  a wide  variety of  applications,  including
Direct-to-Home  (DTH)/Direct  Broadcast  Satellite  (DBS),  business television/
private networks, cable  & telco --  MMDS, switched digital  and digital  cable,
contribution and back-haul links, and satellite distribution to cable head-ends.
 
    MEDIANODE  MN20:    The  MediaNode  MN20  remultiplexes  and  grooms  MPEG 2
transport streams generated by DiviCom and other system components into the form
of a final MPEG 2 transport  stream. The MediaNode MN20 is especially  effective
at  handling  compression  applications  where multiple  video,  audio  and data
signals are required, or complex multichannel  audio needs must be met. It  also
acts as a gateway to and from ATM networks. The MediaNode MN20 can be configured
to  support  a wide  range of  requirements including  statistical multiplexing,
redundant switching, audio only encoding,  scrambling for access control of  the
combined  MPEG  2  transport stream  as  well  as ATM  inputs  and  outputs. The
MediaView   MV20    is    used    for   remultiplexing    MPEG    2    transport
 
                                       90
<PAGE>
streams,    dynamic   rate   optimization,   add/drop   multiplexing,   cascaded
multiplexing, redundant switching, audio-only encoding, data-only  multiplexing,
conditional  access, scrambling  and data  insertion into  the MPEG  2 transport
stream, ATM input, dejittering, formatting and output.
 
    MEDIAVIEW SYSTEM  CONTROLLER SC20:   The  MediaView System  Controller  SC20
utilizes  Windows  NT-TM-  and  HP OpenView-TM-  SNMP  management  software with
DiviCom's applications  to  configure  and monitor  any  collection  of  DiviCom
networked  components. The SC20  offers an easy-to-use  graphical user interface
which includes status,  interconnection maps,  and context  sensitive help.  The
MediaView  SC20  is used  for  system configuration,  encoding  and multiplexing
control, system backup control, monitoring and control at system, component, and
module levels and detection, display, and logging of system faults.
 
    MEDIANODE PLATFORM  MP100:    The  MediaNode Platform  MP100  is  a  Windows
NT-based,  real-time insertion and decoding system.  It allows a user to decode,
record and playback MPEG 2 transport streams through a graphical interface.  The
MP100  comes pre-installed with an MPEG 2 decoder card and media spooler control
software.

    DiviCom has developed a number of extensions and enhancements to Microware's
DAVID OS/9  environment that  DiviCom plans  to augment  and market  as  DiviCom
software.  The type  of software DiviCom  would market would  include FLASH trap
handle,  smartcard   access,  conditional   access  control   query   interface,
application  downloading support and certain  DVB extensions. In addition, there
are many application modules and  unique driver features which DiviCom  provides
that do not involve an API for other applications.
 
    PROFESSIONAL SERVICES AND CUSTOMER SUPPORT
 
    DIVISYS-TM-.   In order to provide its  customers the help they need piecing
together complex digital broadcast television systems, DiviCom launched DiviSys,
a technology  integration group  whose mission  is to  provide a  whole  product
solution  to  DiviCom  customers  for applications  such  as  satellite uplinks,
satellite downlinks, MMDS, ATM networks for content distribution and  automation

program. The  DiviTec  Service Agreement  is  a cost  effective  combination  of
services,  training  and software  designed to  meet each  customer's particular
maintenance  and  upgrade  needs.  There  are  three  distinct  service  options
available  to DiviCom customers through the DiviTec plan. Each plan provides the
customer with varying levels of service  and support designed to match the  size
and scope of the customer's operation.
 
CUSTOMERS
 
   
    DiviCom  sells  the  majority  of its  products  under  contracts  to large,
established  telecommunications,  entertainment,  and  direct-to-home  satellite
companies,  consortia  and  joint ventures  in  North America  and  Europe. Bell
Atlantic, EchoStar and certain SAGEM  Entities, which are two DiviCom  customers
and  one of  its distributor  accounted for  42%, 25%  and 15%  of net revenues,
respectively, in 1995  and 39%, 31%  and 13% of  net revenues, respectively,  in
1994.  During  1993,  no individual  customer  represented  10% or  more  of net
revenues. The following table includes a representative list of customers  based
on revenues and market segment:

    There can be no assurance that such customers will continue to account for a
significant percentage of revenues in the future. The loss of any such customers
could have a material adverse effect on business and results of operations.
 
MARKETING & SALES
 
    DiviCom markets and sells its products in the United States through a direct
sales force with sales and support offices in several cities around the country.
In  Europe, DiviCom  has traditionally sold  its products  through Groupe SAGEM,
which is  based  in France.  DiviCom  is establishing  distributors  in  Norway,
Germany  and  South Africa.  In Asia-Pacific,  DiviCom  sells its  products both
through a direct sales force and through distributors based in Korea, Hong Kong,
Taiwan, Australia, New Zealand and India.
 
    DiviCom promotes its products  to potential customers through  participation
in  major industry trade  shows, through articles  in key industry publications,
through other public relations programs and through advertising.
 
    During 1995  international  revenues  accounted  for  approximately  18%  of
Divicom's  net revenues  and DiviCom  believes that  international revenues will
continue to account for a significant portion of net revenues. DiviCom's success
will depend in part upon its ability to manage international marketing and sales
operations and  manufacturing relationships.  In addition,  DiviCom purchases  a
substantial  proportion of  its raw  materials and  certain key  components from
foreign suppliers. DiviCom's international  manufacturing and sales are  subject
to  changes  in foreign  political and  economic conditions  and to  other risks
including currency  exchange rate  fluctuations  or export/import  controls  and
changes  in  tax  laws, tariffs  and  freight rates.  Certain  foreign countries
comprise  substantial  markets  for  consumer  electronics  products  and  as  a
consequence, any political or economic instability in such
 
                                       92
<PAGE>
countries  could significantly  reduce demand for  products from  certain of the
DiviCom's  major  customers.  DiviCom's  purchases   and  sales  of  goods   are
denominated  in U.S. dollars. Increases in the value of the U.S. dollar relative
to foreign currencies can increase the effective price of and reduce demand  for
DiviCom's  products  relative  to  competitive  products  priced  in  the  local
currency.
 
MANUFACTURING
 
    DiviCom's manufacturing  strategy  is focused  on  the rapid  transition  of
products from engineering development to production. DiviCom makes extensive use
of  the services of electronic component suppliers, referred to as manufacturing
distributors, and subcontract  assembly houses  in order  to minimize  inventory
risks, gain competitive pricing and increase supply flexibility.
 
    DiviCom's  manufacturing group establishes relationships with key supply and
subcontract partners. Electronic component distributors are responsible for  the
procurement and "kitting" of components in preparation for contract assembly.
 
    Once  a  product  or  subsystem has  demonstrated  design  stability,  it is
transitioned from the  DiviCom engineering  group to full  turnkey assembly  and
managed   by  the  manufacturing   distributor.  The  manufacturing  distributor
purchases components  to DiviCom  specifications,  contracts with  the  assembly
facility  to perform product  builds and ships  completed subsystems to DiviCom.
DiviCom conducts  final integration,  system  testing, reliability  and  quality
assurance testing and configuration per customer requirements.
 
    DiviCom's  reliance on subcontractors to  manufacture, assemble and test its
products involves significant  risks, including: reduced  control over  delivery
schedules,  quality assurance, manufacturing yields and cost; the potential lack
of adequate capacity; and  potential misappropriation of DiviCom's  intellectual
property.  DiviCom  obtains manufacturing  capacity  through forecasts  that are
generated in advance of expected delivery dates and are binding on DiviCom.
 
    Although DiviCom has not experienced material disruptions in supply to date,
there can be no assurance that manufacturing or assembly problems will not occur
in the future  or that any  such disruptions  will not have  a material  adverse
effect  upon DiviCom's results of operations. Further, there can be no assurance
that suppliers who have committed to provide product will do so, or that DiviCom
will meet  all  conditions imposed  by  such  suppliers. Failure  to  obtain  an
adequate  supply of products on  a timely basis would  delay product delivery to
DiviCom's customers, which  would have  a material adverse  effect on  DiviCom's
business  and results of operations. In  addition, DiviCom's business could also
be materially  and adversely  affected if  the operations  of any  supplier  are
interrupted  for a substantial period  of time, or if  DiviCom is required, as a
result of capacity  constraints in its  industry or otherwise,  to increase  the
proportion  of goods  purchased from  higher cost  suppliers in  order to obtain
adequate product volumes.
 
    The markets  into which  DiviCom  sells its  products are  characterized  by
extreme price competition, and DiviCom expects the average selling prices of its
products  will decrease  over the  life of each  product. In  order to partially
offset declines  in the  selling price  of its  products, DiviCom  will need  to
reduce  the cost of its products  by implementing cost reduction design changes,
obtaining cost reductions as and  if volumes increase and successfully  managing
manufacturing  and subcontracting relationships. Since  DiviCom does not operate
its own manufacturing facilities and  must make binding commitments to  purchase
products,  it may not be  able to reduce its costs  as rapidly as companies that
operate their own manufacturing facilities. The failure of DiviCom to design and
introduce lower cost  versions of DiviCom's  products in a  timely manner or  to
successfully  manage  its  manufacturing  relationships  would  have  a material
adverse effect on DiviCom's business and results of operations.
 
RESEARCH AND DEVELOPMENT
 
   
    During fiscal 1993, 1994, and  1995, research and development expenses  were
$1.4  million, $8.5 million and $13.5 million, respectively. DiviCom anticipates
that  it  will  continue  to  commit  substantial  resources  to  research   and
development  in the future. As  of June 30, 1996,  DiviCom had over 89 employees
engaged in research and development.
    
 
                                       93
<PAGE>
    DiviCom's current  research  and  development  efforts  focus  on  continued
development  of its MPEG 2 encoders,  MPEG 2 digital networking products, system
control and management software, and settop  box design. The goal is to  provide
essential building blocks to address key market segment needs.
 
    DiviCom's  encoder  system  is  based  on a  C-Cube  encoder  chip  set with
DiviCom's pre-processing capability. DiviCom expects to continue to enhance  the
video  quality and compression efficiency of its  encoder system. For the MPEG 2
digital networking products, DiviCom plans to enhance its capability to  support
multiple  broadcasting  networks such  as DBS,  SDV, HFC,  and ADSL.  For system
control and management software, the focus is on ease of management,  redundancy
support and integration with multiple conditional access systems. The settop box
designs include ASIC designs and interactive TV software development.
 
COMPETITION
 
   
    In its compression and networking business, DiviCom competes with vertically
integrated system suppliers including General Instrument, Scientific Atlanta and
Philips,  as well  as more specialized  suppliers including the  DMV division of
News Corp., Nuko and the TV/COM subsidiary of Hyundai. DiviCom believes that  it
competes favorably based on its expertise and focus in the area of digital video
network   systems  and  its   constituent  components  such   as  digital  video
compression, digital network and  transmission technology. In addition,  DiviCom
possesses   the  practical   knowledge  and   experience  required   to  design,
manufacture, integrate and support such systems in real-world deployments.
    
 
    Several of  these  competitors, including  General  Instruments,  Scientific
Atlanta,  TV/COM, DMV (formerly NTL), Philips  and Wegener have been established
in the analog  technology market  for many  years. Others,  such as  Compression
Labs,  Nuko, Tadiran/Scopus,  and Tiernan, have  come into the  market in recent
years as the early stages of digital technology emerged. The only competitor  to
emerge early with an MPEG 2 product with a discrete design was DMV.
 
    DiviCom  and DiviCom's consumer settop box technology licensees compete with
traditional cable industry settop box suppliers, such as General Instrument  and
Scientific  Atlanta, as well as consumer electronics companies (which may choose
to license DiviCom technology or compete with DiviCom and its licensees) such as
Thomson Consumer  Electronics, Philips,  Sony, Matsushita,  Mitsubishi,  Zenith,
Hyundai,  and Samsung. DiviCom competes by providing chips, software, and system
designs that provide more advanced features more economically than are typically
available elsewhere.
 
    DiviCom expects that  successful companies  in this industry  will be  those
that  provide  the  deployable,  affordable  end-to-end  solutions  that support
open-standard, industry-accepted architectures.  Delivering a  low cost  digital
settop or other highly integrated solution as well as the broadcast video, audio
and  data systems, is a  key factor for successful  participation in the digital
television revolution.
 
    The markets  in which  DiviCom competes  are intensely  competitive and  are
characterized  by declining average selling  prices and rapid technology change.
DiviCom believes that the  principal factors of competition  in its markets  are
product  definition, product design, system cost, functionality, time-to-market,
reliability and reputation. DiviCom believes it competes favorably with  respect
to most of these factors. DiviCom competes with major domestic and international
companies,  most  of  which  have  substantially  greater  financial  and  other
resources  than  DiviCom  with  which  to  pursue  engineering,   manufacturing,
marketing  and  distribution  of their  products.  Some of  these  companies own
proprietary   video   compression   technology   competitive   with    DiviCom's
standards-based  systems.  DiviCom may  also face  increased competition  in the
future from new  entrants into its  markets. In particular,  as the markets  for
DiviCom's  products  develop,  competition  from  large  companies  may increase
significantly. The ability  of DiviCom  to compete successfully  in the  rapidly
evolving markets for high performance audio/video compression technology depends
on  factors  both  within  and  outside of  its  control,  including  success in
designing and subcontracting the manufacture of new products that implement  new
technologies,  adequate sources of raw materials, protection of DiviCom products
by  effective  utilization  of  intellectual  property  laws,  product  quality,
reliability, price and the efficiency of
 
                                       94
<PAGE>
production,  the  pace at  which customers  incorporate DiviCom's  products into
their  products,  success   of  competitors'  products   and  general   economic
conditions.  There can  be no  assurance that  DiviCom will  be able  to compete
successfully in the future.
 
PROPRIETARY RIGHTS
 
    DiviCom uses  various  means to  protect  its proprietary  and  intellectual
property  including non-disclosure agreements,  patents, trademarks, copyrights,
license agreements, contractual agreements and trade secrets.
 
    The DiviCom encoder products are complex custom programmed devices, embedded
software and multi-layer boards, which makes reverse engineering difficult.  The
decoder products contain ASICs which are even more difficult to copy. There are,
however,  no assurances that  they will not  be copied. The  encoder and decoder
products also  incorporate  technology  that  is the  subject  of  seven  patent
applications  filed  in the  United States.  DiviCom has  not filed  for patents
outside the United States. DiviCom's  software, documentation and other  written
materials have only limited protection under copyright and trademark laws. These
products  contain  licensed third  party  content. These  products  also contain
technology (such as required to meet  MPEG standards) for which licenses may  be
needed under terms yet to be determined.
 
    There can be no assurance that DiviCom's means of protecting its proprietary
rights  will be  adequate or that  DiviCom's competitors  will not independently
develop similar technology. There  can be no assurance  that third parties  will
not assert claims against DiviCom with respect to existing or future products or
that  licenses will be available on reasonable terms, or at all, with respect to
any third-party technology including third-party  technology which is or may  be
embodied  in standards. In the event of  litigation to determine the validity of
any third-party claims, such litigation  could result in significant expense  to
DiviCom  and divert the efforts of DiviCom's technical and management personnel,
whether or not such litigation is determined  in favor of DiviCom. In the  event
of  an adverse result in  any such litigation, DiviCom  could be required to pay
substantial amounts  in damages  and  to cease  selling the  infringing  product
unless  and until  DiviCom is  able to  develop non-infringing  technology or to
obtain licenses to the technology which was the subject of the litigation. There
can be no assurance that DiviCom would be successful in such development or that
such licenses would  be available,  and any  such development  or license  could
require expenditure of substantial time and other resources.
 
    DiviCom  believes that the rapid pace  of innovation within its industry and
the skills of  its personnel afford  more protection of  its proprietary  rights
than the various legal means.
 
EMPLOYEES
 
   
    As  of June 30, 1996, DiviCom had a  total of 184 employees, of whom 89 were
engaged  in  research  and  development,  22  in  sales  and  marketing,  22  in
professional  services  and  technical  support,  30  in  operations  and  21 in
administration, finance, MIS and facilities. DiviCom's future success depends in
significant part upon  the continued  service of  its key  technical and  senior
management  personnel and  its continuing ability  to attract,  train and retain
highly qualified  technical  and  managerial  personnel.  Competition  for  such
personnel  in  the video  networking industry  is  intense and  there can  be no
assurance that  DiviCom can  attract,  train or  retain other  highly  qualified
technical  and managerial personnel  in the future.  None of DiviCom's employees
are represented by a labor union. DiviCom has not experienced any work stoppages
and considers its relations with its employees to be good.

           DIVICOM MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
   
    DiviCom  was founded on April 20, 1993. Through December 1994, DiviCom was a
development-stage  company,  principally  engaged  in  developing  MPEG  2-based
systems,  subsystems and  components intended  to enable  the emerging worldwide
digital video infrastructure. Beginning in  January 1995 and continuing  through
the first six months of 1996, DiviCom generated revenues primarily from the sale
of  MPEG 2 real time encoder systems. Product shipments comprise the majority of
DiviCom's revenues, however  DiviCom also earns  maintenance contract and  other
services revenues, and royalty revenues on technology, including advanced MPEG 2
technology  for settop box  and consumer product  applications. In January 1996,
DiviCom  launched  DiviSys,  a   technology  integration  group  that   provides
installation   and  integration  services  for  customer  applications  such  as
satellite up links, satellite  down links, Multichannel Multipoint  Distribution
Systems,  ATM  networks for  content  distribution, and  automation  and control
systems.

YEAR TO YEAR COMPARISONS
 
    NET REVENUES
 
    Net  revenues increased to $34.1 million in 1995 compared to $0.3 million in
1994. Revenues in 1994  consisted primarily of MPEG  digital settop revenue  and
ASIC  design  royalty revenue.  Revenues in  1995 expanded  to include  sales of
DiviCom's family  of  digital video  networking  products including  MPEG  2/DVB
encoders,  MediaNode MN20  remultiplexers and  MediaView System  Controllers. In
1993, DiviCom  generated no  revenues  from operations.  International  revenues
accounted  for 18% of net revenue in  1995. During 1995, Bell Atlantic, Echostar
Communications and the  SAGEM Entities  accounted for 42%,  25% and  15% of  net
revenues,  respectively. During 1994, C-Cube, Bell Atlantic and one of the SAGEM
Entities accounted for 39%, 31% and 13% of net revenues, respectively.
 
    GROSS MARGIN
 
    Gross margin as a percentage of net revenues was 51.8% and 51.1% in 1995 and
1994, respectively.  In the  event that  DiviCom  is not  able to  reduce  costs
sufficiently,  gross margin as a  percentage of net revenues  may decline in the
future as a result of lower average  selling prices on new or existing  products
in  response to potential competitive pressures, and increases in the proportion
of  net  revenues  derived  from   indirect  sales  channels  and   lower-margin
professional services.
 
                                       98
<PAGE>
    RESEARCH AND DEVELOPMENT
 
    Research  and development expenses  were $13.6 million  in 1995, compared to
$8.5 million  in 1994  and $1.4  million  in 1993.  The increase  was  primarily
attributable  to increased staffing  and related expenses  over the same periods
and engineering  charges, such  as  non-recurring engineering  charges,  project
materials  and consulting services, of $5.4 million  in 1995 and $4.1 million in
1994.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
    Selling, general  and administrative  expenses were  $5.3 million  in  1995,
compared  to $2.6 million in 1994 and $0.5 million in 1993. Selling, general and
administrative expenses  increased  each  year due  to  increased  staffing  and
related  expenses,  participation  in domestic  and  international  trade shows,
higher sales commissions associated with increased net revenues and  advertising
and public relations expenses.
 
    INTEREST INCOME (EXPENSE), NET
 
    Interest  income was $163,000, $104,000 and  $39,000 in 1995, 1994 and 1993,
respectively. The increase is primarily due to a corresponding increase in  cash
and  investments  over the  same period,  partially offset  in 1995  by interest
expense on a bank line of credit.
 
    INCOME TAX EXPENSE (BENEFIT)
 
    DiviCom recognized an income tax benefit in 1995 and no income tax provision
or benefit in 1994 and 1993, as DiviCom was in a loss position through 1995.
 
    DiviCom expects to  pay taxes  at or  above the  statutory tax  rate in  the
future  due to  permanent differences relating  to the  treatment of development
funding. Due to these differences, DiviCom does not have any loss carryforwards.
 
   
COMPARISON OF SIX MONTHS ENDED JUNE 30, 1995 AND JUNE 30, 1996
    
 
    NET REVENUES
 
   
    Net Revenues increased 71% to $22.5 million for the first six months of 1996
as compared to $13.2 million for the  first six months of 1995 due to  increased
shipments  of DiviCom's  encoder products.  For the  six months  ending June 30,
1996, Thomson/Tele-TV and Echostar  accounted for 38% and  19% of net  revenues,
respectively.
    
 
    GROSS MARGIN
 
   
    Gross  margin as a  percentage of net revenues  was 56% and  45% for the six
months ending June 30,  1996 and June 30,  1995, respectively. The increase  was
due  to increased sales without a corresponding increase in expenses and greater
manufacturing efficiencies.
    
 
    RESEARCH AND DEVELOPMENT EXPENSES
 
   
    Research and development expenses  decreased to $6.8  million for the  first
six  months of 1996 as compared to $7 million for the same period last year. The
level  of  expenditures  decreased  slightly  over  these  two  periods  despite
increased  staffing  required  to  develop  new  products  and  enhance existing
products, due to  the inclusion  in research and  development costs  in 1995  of
certain  costs related to the use of a number of MPEG 2 encoders in development,
as well as costs of relocating to new development facilities.
    
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
   
    Selling, general and administrative expenses were $4.6 million in the  first
six  months of 1996  compared to $2.1 million  in the first  six months of 1995.
Selling, general and administrative expenses increased due to increased staffing
and related expenses and higher sales commissions associated with increased  net
revenues and an increase in professional services fees.

<PAGE>
    INTEREST INCOME (EXPENSE), NET
 
   
    Interest  income  increased to  $149,000 for  the first  six months  of 1996
compared to $48,000 for the first six months of 1995. The increase is  primarily
due to a corresponding increase in cash and investments over the same period.
    
 
    INCOME TAX EXPENSE (BENEFIT)
 
   
    DiviCom's  effective tax  rate for  the first  six months  of 1996  was 46%.
DiviCom's provision  for  taxes  was  higher than  the  statutory  rate  due  to
permanent differences relating to the treatment of development expenses. DiviCom
expects  to pay  taxes at or  above the statutory  tax rate through  1996 due to
permanent differences relating to the treatment of development funding.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    Since its inception, DiviCom has financed its operations and met its capital
expenditure requirements  primarily  from  development funding  from  the  SAGEM
Entities  and from the  proceeds of private sales  of equity securities. Through
June 30, 1996, DiviCom had received  $17.1 million from development funding  and
$12.1  million from the sale  of equity securities. At  June 30, 1996, DiviCom's
current sources of liquidity included cash and cash equivalents of $10.8 million
and a  bank  line of  credit  in the  amount  of $15  million.  Working  capital
increased  to $11.2 million at June 30,  1996 from $10.6 million at December 31,
1995 principally as a result of the  first six months cash from operations,  and
second quarter cash drawn from the bank line of credit.
    
 
   
    DiviCom's  operating  activities used  cash of  $6.6  million in  1995, $6.1
million in 1994, and $1.3 million in 1993. The use of cash in 1995 was primarily
from higher accounts receivable, deferred taxes and inventory, partially  offset
by  an increase in  deferred revenue, inventory  reserves, and depreciation. The
use of cash from operating activities in 1994 was due to the large net loss  and
increased  inventory  levels, partially  offset by  higher accounts  payable and
deferred revenue. DiviCom's operating  activities used cash  of $1.2 million  in
the  first six months  of 1996 primarily from  increased accounts receivable and
inventory partially offset by increased accounts payable and deferred revenue.
    
 
   
    DiviCom's investing  activities used  cash  of $2.3  million in  1995,  $2.4
million  in 1994, and $0.9  million in 1993, primarily  to purchase property and
equipment. The use  of cash in  1993 was  principally due to  investment in  the
development  of its technology. DiviCom's investing activities used cash of $2.5
million in  the first  six months  of 1996  primarily to  purchase property  and
equipment.   DiviCom's  financing  activities  provided  cash  of  $7.1  million
primarily from bank line of credit and development funds from a stockholder.
    
 
   
    In February 1996, DiviCom  increased its line of  credit from $5 million  to
$15 million. The line will expire in February 1997, and currently bears interest
at  the lender's published prime rate plus 1%, which rate will be reduced to the
prime rate upon DiviCom's  obtaining $8 million  in additional equity.  Advances
under  the line of credit are limited to 80% of eligible accounts receivable and
50% of  inventory. Under  the line  of  credit, DiviCom  is subject  to  various
financial  and other covenants.  The line is  collateralized by DiviCom accounts
receivable and inventory. As of June 30, 1996 DiviCom had utilized $6 million of
its line of credit for working capital purposes.

(1) These options vest  over a  period of  four years  with one  quarter of  the
    original  grant  vesting after  one year  and 1/48th  of the  original grant
    vesting each month thereafter for the next three years. The total number  of
    options  granted to all employees during  the fiscal year ended December 31,
    1995 was 2,612,438.
 
(2) The potential realizable value  is based on  the term of  the option at  its
    time  of grant. The value is calculated  by assuming that the stock price on
    the date  of grant  appreciates  at the  indicated annual  rates  compounded
    annually  for the entire term of the option and that the option is exercised
    and the underlying  shares are sold  on the last  day of its  term for  such
    appreciated  stock price. The assumed 5%  and 10% rates of annual compounded
    stock appreciation over the full ten-year  term of the options are  mandated
    by  the rules of the  Commission and do not  represent DiviCom's estimate or
    projection of future Common  Stock prices. Using  this specified method,  no
    gain  to the optionee is possible unless  the stock price increases over the
    option term, which will benefit all stockholders.

(2) At  December 31, 1995, stock options granted to employees could be exercised
    prior to  vesting  in  exchange  for  shares  of  Common  Stock  subject  to
    repurchase  at original cost by DiviCom until vested under the same schedule
    of terms and restrictions imposed on the original option grants.

    The authorized capital  stock of  C-Cube consists of  150,000,000 shares  of
Common  Stock, $0.001 par value, and 5,000,000 shares of Preferred Stock, $0.001
par value.
 
    COMMON STOCK.   As  of May  31, 1996,  there were  approximately  33,086,488
shares  of C-Cube Common  Stock outstanding and held  of record by approximately
622 stockholders.  C-Cube Common  Stock is  listed on  Nasdaq under  the  symbol
"CUBE". Holders of C-Cube Common Stock are entitled to one vote per share on all
matters  to be voted  upon by the  stockholders. The stockholders  do not have a
right to  take  action  by  written  consent nor  may  they  cumulate  votes  in
connection  with the election of Directors. Special meetings of stockholders may
be called only by a majority of the Board of Directors or by holders of not less
than ten percent of the shares entitled  to cast votes at such special  meeting.
Any  amendment by the stockholders of the  Bylaws of C-Cube and the amendment by
the  stockholders  of  various  provisions   of  the  Restated  Certificate   of
Incorporation,  including  the  provisions  concerning  stockholder  voting  and
stockholder written consents, requires  the affirmative vote  of the holders  of
two-thirds  of  the outstanding  capital stock  of C-Cube  voting together  as a
single class in addition to any other vote required by law or by the Certificate
of Incorporation of C-Cube. The holders  of C-Cube Common Stock are entitled  to
receive  ratably such dividends, if any, as may be declared from time to time by
the Board of Directors out of funds legally available therefor. In the event  of
a liquidation, dissolution or winding up of C-Cube, the holders of C-Cube Common
Stock  are entitled to  share ratably in  all assets remaining  after payment of
liabilities. The C-Cube Common Stock has  no preemptive or conversion rights  or
other  subscription rights. There  are no redemption  or sinking fund provisions
applicable to the C-Cube Common Stock.  All outstanding shares of C-Cube  Common
Stock  are fully paid and non-assessable, and  the shares of C-Cube Common Stock
to be  outstanding  upon  completion  of  the Merger  will  be  fully  paid  and
non-assessable.
 
    PREFERRED STOCK.  C-Cube has 5,000,000 shares of Preferred Stock authorized,
none of which are outstanding. The Board of Directors has the authority to issue
the  shares of  Preferred Stock in  one or  more series, to  determine, alter or
eliminate any or  all of  the rights, preferences,  privileges and  restrictions
granted to or imposed upon any wholly unissued series of Preferred Stock, to fix
the number of shares constituting any series and the designations of such series
and  to provide  for the  rights and  terms of  redemption or  conversion of the
shares  of  any  such  series,  without  any  further  vote  or  action  by  the
stockholders.  Although it  presently has  no intention to  do so,  the Board of
Directors, without stockholder approval, can  issue Preferred Stock with  voting
and  conversion rights  which could adversely  affect the voting  power or other
rights of the holders  of C-Cube Common Stock.  The issuance of Preferred  Stock
may  have the effect of delaying, deferring or preventing a change in control of
C-Cube.
 
    TRANSFER AGENT AND  REGISTRAR.   The Transfer  Agent and  Registrar for  the
C-Cube  Common Stock  is Boston Equiserve,  L.P., Investor  Relations, P.O. 644,

5,500,000 shares of which are designated Series B Preferred.
 
    COMMON STOCK.  As of the DiviCom Record Date, there were           shares of
DiviCom Common  Stock outstanding  and  held of  record by  approximately
stockholders.  Holders of DiviCom Common Stock  have no right to convert DiviCom

Stock are validly issued, fully paid and nonassessable.
 
    PREFERRED STOCK.   As  of the  DiviCom Record  Date, there  were issued  and
outstanding  15,788,000 shares  of Series  A Preferred  and 5,500,000  shares of
Series B  Preferred. The  principal rights,  privileges and  preferences of  the
issued  and  outstanding shares  of DiviCom  Preferred Shares  are as  set forth
below.
 
                                      106
<PAGE>
    DIVIDENDS.  No dividends may be paid on any shares of DiviCom's Common Stock
unless a dividend is  paid with respect to  all outstanding shares of  DiviCom's
Preferred  Stock in an amount for each  share of DiviCom's Preferred Stock equal
to or greater  than the aggregate  amount of  such dividends for  all shares  of
DiviCom's  Common Stock into which each  such share of DiviCom's Preferred Stock
could then be converted.
 
   
    LIQUIDATION.  In the event of any liquidation, dissolution or winding up  of
DiviCom  (which,  as defined  in DiviCom's  Certificate of  Incorporation, would
include the Merger) holders of the Series A Preferred and Series B Preferred are
entitled to receive, prior and in  preference to any distribution of any  assets
of  DiviCom to the holders  of DiviCom Common Stock,  $0.40 and $1.00 per share,
respectively. After the holders of the DiviCom Preferred Stock have received the
full amount of their liquidation preferences, the holders of the DiviCom  Common
Stock  and the  DiviCom Preferred  Stock are  entitled to  receive all remaining
assets of DiviCom  available for  distribution on  a pro  rata basis  as if  all
shares  of the  DiviCom Preferred  Stock were  converted into  shares of DiviCom
Common Stock. If the Certificate Amendment  is approved, the Merger will not  be
treated as a liquidation and the holders of Preferred Stock will not be entitled
to a liquidation preference in the Merger.
    
 
    CONVERSION.   Each  share of  Series A Preferred  and Series  B Preferred is
presently convertible into one share of DiviCom Common Stock subject to  certain
anti-dilution adjustment provisions.
 
   
    CERTAIN  PROTECTIVE PROVISIONS.  So long  as any shares of DiviCom Preferred
Stock remain outstanding, approval of the holders of at least two-thirds of such
shares is  required to  amend the  DiviCom Certificate  of Incorporation,  issue
Common  Stock if the number of remaining unissued shares is less than the number
of shares Common Stock into which  the Preferred Stock could then be  converted,
effect  the reclassification, recapitalization  or other change  of any stock or
effect the  sale, lease,  assignment, transfer  or other  conveyance of  all  or
substantially  all of the  assets of the DiviCom  including any consolidation or
merger  involving  DiviCom  (which,  as  defined  in  DiviCom's  Certificate  of
Incorporation,  would include the Merger.) In addition, the holders of shares of
Series A Preferred have  rights to purchase  certain DiviCom product  technology
for  $1 and all other  assets at fair market value  upon an election to dissolve
DiviCom. If the Certificate Amendment is approved, the rights of the holders  of
Series A Preferred to purchase such assets on dissolution shall be deleted.
    
 
   
    PREEMPTIVE  RIGHTS.  Each stockholder who owns shares representing more than
five percent of  the outstanding shares  of DiviCom possesses  a right of  first
refusal  to purchase a pro rata share of any issuance of new securities (as such
term is defined in DiviCom's Certificate  of Incorporation) offered for sale  by
DiviCom. For purposes of determining a stockholder's percentage of ownership and
pro  rata share, the number of shares of  DiviCom Common Stock to be used in the
calculation assumes the full conversion of all Preferred Stock and the  exercise
of  all options. If the Certificate Amendment is approved, the preemptive rights
provision shall be deleted.
    
 
    VOTING RIGHTS.  Subject  to the protective  provisions described above,  and
except  as otherwise  required by  law, the holders  of the  Series A Preferred,
Series B  Preferred and  DiviCom Common  Stock  are entitled  to notice  of  any
stockholders'  meeting  and  to  vote  together as  one  class  upon  any matter
submitted to the stockholders for a vote on the following basis:
 
        (a)   COMMON  VOTE.   Each  share of  DiviCom  Common Stock  issued  and
    outstanding has one vote.
 
        (b)   PREFERRED  VOTE.  Each  share of  Series A Preferred  and Series B
    Preferred issued  and outstanding  has that  number of  votes equal  to  the
    number  of shares of DiviCom Common  Stock into which such DiviCom Preferred
    Stock could be converted rounded to the nearest whole share.
 
    Notwithstanding the normal voting  provisions described above, each  DiviCom
stockholder  may cumulate such holder's votes at all elections of directors. The
total number of votes in the election of directors to which each stockholder  is
entitled   is   the   number   of   shares   of   DiviCom   Common   Stock  held
 
                                      107
<PAGE>
by  such  stockholder,  including  the  conversion  of  all  Preferred   Shares,
multiplied  by the number of directors to  be elected. Each stockholder may cast
all such votes for a single director or may distribute them among any number  of
the directors to be elected in any manner that such stockholder sees fit.
 
                   COMPARISON OF RIGHTS OF HOLDERS OF C-CUBE
               COMMON STOCK AND HOLDERS OF DIVICOM CAPITAL STOCK
 
   
    Upon  consummation of the  Merger, the holders of  shares of DiviCom Capital
Stock will receive cash and shares of C-Cube Common Stock in exchange for  their
shares  of DiviCom Capital Stock.  As of the Effective  Time, holders of DiviCom
Capital Stock  will no  longer  be entitled  to  certain rights  and  privileges
previously  provided for in DiviCom's  Certificate of Incorporation. Such rights
include the preemptive right  granted to all  DiviCom stockholders holding  more
than five percent of DiviCom's Capital Stock to purchase a pro rata share of any
issuance  of  new securities  and the  right of  all stockholders  to cumulative
voting in the election of directors.  Such rights also include those  separately
granted  to the holders of DiviCom's Preferred Stock including (i) a liquidation
preference in the amounts described above, (ii) a protection provision  ensuring
dividends  of at  least an equal  amount paid  to any holders  of DiviCom Common
Stock as described above, (iii) certain anti-dilution adjustments upon  dilutive
issuances of DiviCom Capital Stock, and (iv) a right to vote as a separate class
requiring  an approval of  at least two-thirds of  such share concerning certain
corporate transactions  including the  Merger. Under  Delaware law,  dissenters'
rights  will be available to stockholders of DiviCom with respect to the Merger.
See  "Approval  of  the  Merger  and  Related  Transactions  --  Appraisal   and
Dissenters' Rights."
    
 
   
    In  addition, certain  other rights  and privileges  of DiviCom stockholders
will also change as a result of the Merger. Upon completion of the Merger,  each
former   DiviCom  stockholder  will  have  a  substantially  smaller  percentage
ownership of  C-Cube than  such stockholder's  current percentage  ownership  of
DiviCom.  Accordingly,  former DiviCom  stockholders  will have  a significantly
smaller voting influence on a percentage  basis over the affairs of C-Cube  than
currently enjoyed over the affairs of DiviCom.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Stockholders of
 C-Cube Microsystems Inc.:
 
    We  have  audited the  accompanying  consolidated balance  sheets  of C-Cube
Microsystems Inc. and  subsidiaries as of  December 31, 1995  and 1994, and  the
related  consolidated statements  of operations,  stockholders' equity  and cash
flows for each of the three years  in the period ended December 31, 1995.  These
financial  statements are  the responsibility  of the  Company's management. Our
responsibility is to express an opinion  on these financial statements based  on
our audits.
 
    We  conducted  our audits  in  accordance with  generally  accepted auditing
standards. Those standards require that we plan and perform the audit to  obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In  our opinion, such  consolidated financial statements  present fairly, in
all material respects, the  financial position of  C-Cube Microsystems Inc.  and
subsidiaries  at December 31, 1995 and 1994, and the results of their operations
and their cash flows for  each of the three years  in the period ended  December
31, 1995 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
NOTE 1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION
 
    C-Cube  Microsystems  Inc. (the  "Company") was  founded  in July  1988. The
Company is a  leading provider  of powerful,  highly integrated  standards-based
digital  video compression solutions. The  Company's innovative encoder, decoder
and codec products enable high-quality full-motion video and still images to  be
cost-effectively provided by a broad range of end user systems.
 
CONSOLIDATION
 
    The  consolidated financial statements include the Company, its wholly owned
subsidiaries and Kubota  C-Cube, Inc.  (a 65% owned  Japanese subsidiary)  after
elimination of intercompany accounts and transactions.
 
CASH AND EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
    All  highly liquid debt  instruments purchased with  an original maturity of
three months or less are classified as cash equivalents.
 
    Management determines the  classification of debt  and equity securities  at
the  time of purchase  and reevaluates the classification  at each balance sheet
date. Debt  securities are  classified as  available-for-sale when  the  Company
generally  has the ability and intent to  hold such securities to maturity, but,
in certain circumstances, may  potentially dispose of  such securities prior  to
their  maturity. Securities available-for-sale  are reported at  fair value with
unrealized gains and losses  reported as a  separate component of  stockholders'
equity.  All  available-for-sale  securities  mature within  12  months  and are
classified as current assets.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (first-in, first-out) or market.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are  stated at cost.  Depreciation is provided  using
the  straight-line method over estimated useful  lives of three years. Equipment
under capital lease and leasehold improvements are amortized over the shorter of
their estimated  useful lives  or the  lease term,  generally three  years.  The
Company  adopted  SFAS No.  121, "Accounting  for  the Impairment  of Long-Lived
Assets and for Long-Lived Assets to  be Disposed Of" effective January 1,  1995.
The  adoption  of  this  statement  had no  effect  on  the  Company's financial
condition or results of operations.
 
INVESTMENTS IN COMPANIES
 
    Investments in 20% to 50% owned companies are accounted for using the equity
method. Investments in less than 20% owned companies are accounted for using the
cost method  unless  the  Company  can exercise  significant  influence  or  the
investee  is economically dependent  upon the Company, in  which case the equity
method is used. Such investments are included in other assets.
 
REVENUE RECOGNITION
 
    The Company records product sales to customers and distributors at the  time
of  shipment. Certain of  the Company's agreements  with its distributors permit
limited stock rotation and provide for price protection. Allowances for  returns
and  adjustments  are provided  at the  time  sales are  recorded and  for price
protection when the Company reduces its published list prices.
 
    Revenue  from  product  development  agreements  is  recognized  using   the
percentage of completion method. Estimates are reviewed and revised periodically
throughout  the  lives  of the  contracts.  Any  revisions are  recorded  in the
accounting period in which the revisions are made.

                  YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
NOTE 1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
RESEARCH AND DEVELOPMENT
 
    Research and development expenses include costs and expenses associated with
the  development  of  the  Company's  design  methodology  and  the  design  and
development  of  new products,  including  initial nonrecurring  engineering and
product  verification  charges  from  foundries.  Research  and  development  is
expensed as incurred.
 
INCOME TAXES
 
    The  Company accounts  for income taxes  pursuant to  Statement of Financial
Accounting Standards No. 109, which requires an asset and liability approach  to
account  for income taxes  and requires recognition  of deferred tax liabilities
and assets for  the expected  future tax consequences  of temporary  differences
between the financial statement carrying amounts and the tax bases of assets and
liabilities and net operating loss and tax credit carryforwards.
 
ESTIMATES
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that affect reported  amounts of assets,  liabilities, revenues and
expenses as of the  dates and for the  periods presented. Significant  estimates
include  the  allowance for  doubtful accounts,  provisions for  stock rotation,
price protection  and warranty  as  well as  realization of  intangible  assets.
Actual results could differ from those estimates.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    Financial  instruments include cash  equivalents, short-term investments and
convertible subordinated notes. Cash equivalents and short-term investments  are
stated  at fair value based  on quoted market prices.  Fair value of convertible
subordinated notes  is  estimated by  obtaining  quoted market  prices  adjusted
through interpolation where necessary for maturity differences.
 
CONCENTRATION OF CREDIT RISK
 
    Financial   instruments   which   potentially   subject   the   Company   to
concentrations of credit risk consist primarily of cash equivalents,  short-term
investments  and trade  accounts receivable. By  policy, the  Company places its
investments only with financial institutions meeting its credit guidelines  and,
other  than U.S. Government Treasury instruments, limits the amounts invested in
any one institution or in  any type of instrument.  Almost all of the  Company's
trade  accounts  receivable  are  derived from  sales  to  manufacturers  in the
consumer electronics, computer and communications markets. The Company  performs
ongoing credit evaluations of its customers' financial condition and manages its
exposure  to losses  from bad  debts by limiting  the amount  of credit extended
whenever deemed necessary and generally does not require collateral.
 
PRODUCT AND GEOGRAPHIC RISKS
 
    Beginning in the second quarter of  1995, sales of the Company's CL480  have
represented  an increasingly significant  percentage of the  Company's total net
revenues. The Company expects  that revenues from its  CL480 will account for  a
significant portion of its product revenues in 1996. Declines in demand for this
product,  whether as a result of competition, technological change or otherwise,
would have a material  adverse effect on the  Company's business and results  of
operations.
 
    The  Asian consumer  electronics market  comprises a  substantial market for
products utilizing  the  Company's  CL480,  such  as  Video  CD  players.  As  a
consequence,  any political, economic  or other instability  in the region could
significantly reduce demand  for products  from certain of  the Company's  major
customers.

NOTE 1.  ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
FOREIGN CURRENCY TRANSLATION
 
    The  functional currency of  Kubota C-Cube is  the Japanese yen. Accordingly
all assets  and liabilities  of  Kubota C-Cube  are  translated at  the  current
exchange  rate  at the  end  of the  period and  revenues  and costs  at average
exchange rates in effect  during the period. Gains  and losses from  translation
are recorded directly into a separate component of stockholders' equity. Foreign
currency transaction gains and losses were immaterial in 1995, 1994, and 1993.
 
AMORTIZATION OF DISTRIBUTION RIGHTS
 
    As  a result of the Company increasing  its ownership interest in KCC to 65%
at December 31, 1992, an additional  $1,236,000 equity in loss of joint  venture
was  recorded to  reflect the  Company's additional  losses attributable  to its
previously held 35% interest through December 31, 1992. The Company  capitalized
$2,471,000  as distribution rights and will  amortize this intangible asset over
its expected useful life of 15 years. Accumulated amortization was $494,000  and
$330,000  at December 31, 1995 and 1994, respectively. The Company evaluates the
recoverability of this asset based on estimated future undiscounted cash flows.
 
    During 1995, the Company and Kubota contributed additional equity to KCC and
the Company  recorded  a  $768,000  adjustment to  paid-in  capital  to  reflect
subsidiary losses previously recognized.
 
RECENTLY ISSUED ACCOUNTING STANDARD
 
    In  October 1995, the Financial  Accounting Standards Board issued Statement
No. 123, "Accounting for Stock-Based  Compensation." The new standard defines  a
fair  value method of accounting for stock options and other equity instruments,
such as stock purchase plans. Under  this method, compensation cost is  measured
based  on the fair value of the stock award when granted and is recognized as an
expense over  the service  period, which  is usually  the vesting  period.  This
standard  will  be effective  for the  Company beginning  in 1996,  and requires
measurement of awards made beginning in 1995.
 
    The new  standard  permits  companies  to continue  to  account  for  equity
transactions  with  employees  under  existing  accounting  rules,  but requires
disclosure in a note to the financial statements of the pro forma net income and
earnings per share as if the company  had applied the new method of  accounting.
The  Company intends  to follow these  disclosure requirements  for its employee
stock plans. As  a result,  adoption of  the new  standard will  not impact  the
Company's results of operations.
 
NET INCOME (LOSS) PER SHARE
 
    Net  income (loss)  per share  is based  on the  weighted average  number of
common and dilutive  common equivalent shares  (convertible preferred stock  and
common stock options) outstanding during 1995 and 1994. Pursuant to rules of the
Securities  and Exchange Commission Staff, all  common shares issued and options
to purchase shares of common stock granted  by the Company at a price less  than
the  initial  public  offering  price during  the  twelve  months  preceding the
offering date  (using the  treasury stock  until shares  are issued)  have  been
included  in the computation of common  and common equivalent shares outstanding
for periods prior to the April 1994 initial public offering.
 
NOTE 2.  ACQUISITIONS
    On November 17, 1995,  the Company acquired all  of the outstanding  capital
stock  of  Media Computer  Technologies, Inc.  ("MCT"), a  fabless semiconductor
company marketing video  based products,  for cash of  $6.35 million,  including
$100,000  of acquisition costs. The Company  withheld $1,125,000 of the purchase
price which  is included  in  long-term obligations  as  of December  31,  1995.
Results  of  MCT  since the  acquisition  have  been included  in  the Company's
results. The acquisition

    The purchased technology and goodwill are each being amortized over 5 years.
The $3,800,000 allocated to in-process research and development was expensed  at
the time of the acquisition.
 
    The  Company  also  entered into  agreements  with former  employees  of MCT
providing for additional  incentive payments  of up to  $1.125 million,  payable
over  a  3  year  period  upon the  achievement  of  performance  milestones and
contingent upon continued employment with the Company.
 
    The following  unaudited pro  forma  information presents  the  consolidated
results  of operations  as if  the acquisition had  occurred on  January 1, 1994
excluding the write-off of in-process research and development and after  giving
effect  to certain adjustments including amortization of identifiable intangible
assets and  goodwill, reduction  in  investment income  for utilization  of  the
Company's  cash  and investments  to finance  the  acquisition, and  related tax
effects. The pro forma results have been prepared for information purposes  only
and  do  not  purport to  be  indicative of  what  would have  occurred  had the

NOTE 6.  LINE OF CREDIT AND NOTES PAYABLE TO BANKS
    At December 31, 1995, the  Company had an available  bank line of credit  of
$8,500,000  which expires August 1, 1996. Borrowings bear interest at the bank's
prime rate (8.5% at December 31, 1995). The line of credit required the  Company
to  comply with certain  financial covenants, and the  Company was in compliance
with all of the covenants at December  31, 1995. There were no borrowings  under
this  line  at  December 31,  1995.  In January  1996,  the line  of  credit was
increased  to  $20,000,000.  This  line  is  collateralized  by  the   Company's
receivables, inventory and fixed assets. The new agreement requires the Company,
among  other things, to maintain a tangible  net worth, as defined and including
convertible subordinated debt, of $152,534,000, 80% of its tangible consolidated
assets within the U.S.  parent company, quarterly net  income (no more than  one
quarterly  loss per fiscal year), a quick ratio of 1.75 to 1, and a maximum debt
to tangible net  worth (as defined)  ratio of .75  to 1. In  addition, the  bank
agreement prohibits the payment of cash dividends.
 
    Notes  payable  to banks  of $1,934,000  ($5,422,000  at December  31, 1994)
represent yen denominated borrowings  of Y200,000,000 (Y540,000,000 at  December
31,  1994) by the Company's Japanese  subsidiary, Kubota C-Cube, with a weighted
average interest rate of 3%  at December 31, 1995.  The notes expire on  various
dates  through 1996; however, the minority  shareholder in Kubota C-Cube, Kubota
Corporation, agreed  to  continue to  guarantee  decreasing amounts  during  the
following  periods: up to Y450,000,000,  Y250,000,000 and Y125,000,000 following
the first,  second and  third  anniversaries of  the  closing of  the  Company's
initial  public offering  of common stock  (April 28,  1994), respectively, with
such guarantee expiring three years and six months after such closing. If Kubota
Corporation is required  to make  a payment under  the loan  guarantee, and  the
Company  has not  reimbursed such  payment by March  31, 1996,  the Company will
issue to Kubota Corporation a

    In  November  1995,  the  Company  completed  a  public  debt  offering   of
$86,250,000  aggregate principal  amount of convertible  subordinated notes. The
notes mature in 2005. Interest is payable semi-annually at 5.875% per annum. The
notes are  convertible at  the option  of the  note holders  into the  Company's
common  stock at  an initial  conversion price of  $30.70 per  share, subject to
adjustment. Beginning in November, 1997, the notes are redeemable at the  option
of the Company at an initial redemption price of 104.7% of the principal amount.
The  Company has reserved 2,809,446 shares of common stock for the conversion of
these notes. Offering costs of $2,853,000  are included in other assets and  are
amortized on a straight-line basis as an adjustment to interest expense over the
term of the notes.

EMPLOYEE STOCK PURCHASE PLAN
 
    The Company  has  an employee  stock  purchase plan,  under  which  eligible
employees  may authorize payroll  deductions of up to  10% of their compensation
(as defined) to purchase common  stock at a price equal  to 85% of the lower  of
the  fair market values as  of the beginning or the  end of the offering period.
During 1995, 138,000  shares of  common stock were  issued under  this plan.  At
December  31, 1995, 225,000  shares of common stock  were available for issuance
under this plan.
 
DEFERRED STOCK COMPENSATION
 
    In connection with the grant of certain stock options to employees in  1993,
the  Company recorded deferred stock compensation of $980,000 for the difference
between the deemed fair  value for accounting purposes  and the option price  as
determined  by the  Board at the  date of grant.  Such amount is  presented as a
reduction of stockholders'  equity and  is amortized over  the 48-month  vesting
period  of the  related stock  options. In  connection with  the grant  of stock
options to  employees  in  the  first quarter  of  1994,  the  Company  recorded
additional  deferred stock compensation of $615,000 which will be amortized over
the 48-month vesting period of such options.

    At  December  31,  1995,  the   Company  has  foreign  net  operating   loss
carryforwards of approximately $4,600,000 which expire through 1998.
 
    The  reduction in the  valuation allowance from 1994  to 1995 of $13,626,000
recognized the tax  benefit of net  operating losses utilized  by the  Company's
earnings.  The remaining  valuation allowance  relates to  foreign net operating
losses which the Company believes may not be realized.
 
NOTE 11.  EMPLOYEE BENEFIT PLAN
    The Company has a 401(k) tax-deferred savings plan under which  participants
may  contribute up  to 20%  of their  compensation, subject  to certain Internal
Revenue Service limitations.  The Company  has not  contributed to  the plan  to
date.
 
NOTE 12.  RELATED PARTIES
    The  Company has agreed with a  stockholder who had guaranteed capital lease
obligations to the extent of $3 million and who held a security interest in  all
of  the  Company's intangible  assets  to substitute  a  security interest  in a
separate bank account established and funded in an amount equal to the remaining
related lease payments (approximately $0.5 million) in exchange for  terminating
its  security interest  in the Company's  intangible assets.  Restricted cash is
included with other current assets and other assets in the 1995 balance sheet.
 
    A director and officer of the Company was also a director of a company  with
which  the Company  has entered  into a  development agreement  providing, among
other things, for the development  of certain products to  be used in the  other
party's products and the licensing of certain of the Company's technology to the
other  party for its  use in developing  its products. In  addition, in 1994 and
1993, the Company  acquired approximately a  7% interest in  this company for  a
total  of $237,000. The Company  subleased office space to  this company in 1994
and  1993  and   received  income   of  approximately   $34,000  and   $118,000,
respectively.
 
NOTE 13.  DEVELOPMENT AGREEMENTS
    The  Company  enters into  development agreements  with other  companies for
which it  receives  development  fees  with  certain  payments  contingent  upon
attaining  contract milestones. The  Company generally retains  ownership of the
products developed  under the  agreements; however,  some agreements  limit  the
product  markets  in  which  the  Company may  sell  the  developed  product. In
addition, under  certain of  the  agreements, the  Company  is required  to  pay
royalties based on a percentage of the net sales of the products developed under
the  agreements. Royalty  expense was $574,000  in 1995, $1,377,000  in 1994 and
$622,000 in 1993.

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
    
 
   
    1.  BASIS OF PRESENTATION
    
 
   
    In  the  opinion  of  management,  these  unaudited  condensed  consolidated
financial  statements  include  all  adjustments,  consisting  only  of   normal
recurring  adjustments and accruals,  C-Cube Microsystems Inc.  ("C-Cube" or the
"Company")  considers  necessary  for  a  fair  presentation  of  the  Company's
financial  position as of June 30, 1996,  and the results of operations and cash
flows for  the quarters  and  six months  ended June  30,  1996 and  1995.  This
unaudited  quarterly information should be read  in conjunction with the audited
consolidated financial statements of  C-Cube and the  notes thereto included  in
the  Company's Annual  Report to  Stockholders for  the year  ended December 31,
1995.
    
 
   
    The growth in revenues  and operating income experienced  by the Company  in
recent quarters is not necessarily indicative of future results. In addition, in
view   of  the  significant  growth  in   recent  years,  C-Cube  believes  that
period-to-period comparisons of its financial results should not be relied  upon
as an indication of future performance.

    3.  WAFER SUPPLY AGREEMENT
    
 
   
    In  the  second  quarter of  1996  the  Company expanded  and  formalized it
relationship with  Taiwan Semiconductor  Manufacturing Corporation  ("TSMC")  to
provide  additional wafer production  capacity over the  1996 to 2001 timeframe.
The agreement with TSMC  requires C-Cube to make  two advance payments  totaling
$49  million. The first advance payment of  $24.5 million was made in June 1996,

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
DiviCom Inc.:
 
    We  have  audited the  accompanying  balance sheets  of  DiviCom Inc.  as of
December  31,  1994  and  1995,  and  the  related  statements  of   operations,
stockholders'  equity and  cash flows for  each of  the two years  in the period
ended December 31, 1995 and the nine month period ended December 31, 1993. These
financial statements are  the responsibility  of the  Company's management.  Our
responsibility  is to express an opinion  on these financial statements based on
our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also  includes
assessing  the  accounting principles  used  and significant  estimates  made by
management, as well as evaluating the overall financial statement  presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In  our opinion, the financial statements  referred to above present fairly,
in all material respects, the financial position of DiviCom Inc. as of  December
31, 1994 and 1995, and the results of its operations and its cash flows for each
of the two years in the period ended December 31, 1995 and the nine month period
ended  December  31,  1993  in  conformity  with  generally  accepted accounting
principles.

                     (IN THOUSANDS, EXCEPT PER SHARE DATA)
 
1.  FORMATION AND BUSINESS OF THE COMPANY:
    DiviCom,  Inc. (the Company) was incorporated  on April 20, 1993 to develop,
manufacture and market communications products  which merge the technologies  of
video  and audio  compression with  digital communication.  Through December 31,
1994, the Company had been primarily  engaged in developing its initial  product
technology, recruiting personnel and raising capital.
 
    The  Company has several product  families for video networking applications
including: MediaView,  a high  performance MPEG  2 encoder;  MediaNode, a  video
networking platform and control system; and ProView, a MPEG 2 commercial decoder
family.
 
    Product  shipments comprise the majority  of the Company's revenues, however
the Company also earns maintenance contract and royalty revenues on services and
technology, including  DiVA,  advanced MPEG  2  technology for  settop  box  and
consumer  product applications. The Company's products are marketed in North and
South America, Europe and Asia Pacific.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    MANAGEMENT ESTIMATES:
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that  affect the  reported  amounts of  assets and  liabilities  and
disclosure  of contingent  assets and liabilities  at the date  of the financial
statements and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS:
 
    The  Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents. Substantially all the
Company's cash and cash equivalents are held at one financial institution.
 
    REVENUE RECOGNITION:
 
    Revenue from product sales is recognized upon delivery, net of an  allowance
for  returns, provided no  significant obligations remain  and collection of the
receivable is deemed probable.
 
    CONCENTRATION OF CREDIT RISK:
 
    The Company sells  the majority of  its products under  contracts to  large,
established  telecommunications,  entertainment,  and  direct-to-home  satellite
companies, consortia  and  joint  ventures  in North  America  and  Europe.  Two
customers  and one distributor accounted  for 42%, 25% and  15% of net revenues,
respectively, in 1995, with  one customer accounting for  40% of total  accounts
receivable at December 31, 1995.
 
    WARRANTY RESERVE:
 
    The  Company has estimated and accrued costs related to the warranty offered
on its product lines. The stated warranty period is one year for components, and
90 days for labor. Due to the fact that the technology is relatively new, it  is
undergoing certain modifications and modifications based on field performance.
 
    The Company does not have significant historical data with which to estimate
warranty  costs because the products were  only introduced within the last year.
Although the  warranty reserve  is  considered adequate  in the  Company's  best
judgment, it is reasonably possible that the cost of upgrade and modification to
systems  in  the field  could exceed  the estimated  warranty reserve,  and that
additional expense could result.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    INVENTORY:
 
    Inventory is  stated  at  the  lower of  cost  (determined  on  a  first-in,
first-out basis) or market.
 
    PROPERTY AND EQUIPMENT AND ORGANIZATION COSTS:
 
    Property  and equipment  and organization costs  are stated at  cost and are
depreciated on a straight line basis over their estimated useful lives of  three
years.
 
    RESEARCH AND DEVELOPMENT:
 
    Research and development costs and software development costs are charged to
operations as incurred. Intellectual property rights are expensed on acquisition
due to uncertainty regarding their useful lives.
 
    INCOME TAXES:
 
    The  Company  accounts  for income  taxes  in accordance  with  Statement of
Financial Accounting  Standards,  No. 109  (SFAS  109), "Accounting  for  Income
Taxes." Under SFAS 109, deferred tax assets and liabilities are determined based
on  differences  between  financial  reporting  and  tax  bases  of  assets  and
liabilities and are measured using the enacted  tax rates and laws that will  be
in effect when the differences are expected to affect taxable income.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123:
 
    The  Financial  Accounting  Standards Board  issued  Statement  of Financial
Accounting Standards No.  123, "Accounting for  Stock-Based Compensation"  (SFAS
No.  123) in October 1995. This accounting  standard permits the use of either a
fair value based method or the  current Accounting Principles Board Opinion  25,
"Accounting  for Stock Issued to Employees"  (APB 25) when accounting for stock-
based compensation arrangements. Companies that do not follow the new fair value
based method will be required  to disclose pro forma  net income computed as  if
the  fair value based method had been applied. The disclosure provisions of SFAS
No. 123  are effective  for  fiscal years  beginning  after December  15,  1995.
Management  has not determined if  it will adopt the  fair value based method of
accounting for stock-based compensation arrangements nor the impact of SFAS  No.
123 on the Company's consolidated financial statements.

5.  STOCKHOLDERS' EQUITY:
 
    AUTHORIZED CAPITAL STOCK:
 
    The  Company's authorized capital stock consists  of 35,750 shares of common
stock, 15,788 shares of Series  A preferred stock and  5,500 shares of Series  B
preferred stock.
 
    CONVERTIBLE PREFERRED STOCK:
 
    Preferred  shares are convertible  to common shares at  a rate determined by
dividing  $0.40  and  $1.00  for  Series   A  and  Series  B  preferred   stock,
respectively,  by the conversion price applicable  to such shares upon surrender
of  certificate  for   conversion.  Conversion  is   either  at  the   preferred
stockholders'  option or automatic  upon (1) an  underwritten public offering of
the Company's common stock for  a public offering price  of not less than  $2.80
per  share and $10,000 in aggregate or (2)  written request of the holders of at
least two-thirds of the preferred stock  then outstanding. At December 31,  1994
and  1995,  15,788 and  21,288 shares  of  the Company's  common stock  had been

    The Company's  preferred stock  has voting  rights equal  to the  number  of
common  shares  into which  they convert  on the  record date  for the  vote. In
addition, holders  of  preferred stock  are  entitled to  elect  directors  with
respect  to their shares  of stock multiplied  by the number  of directors to be
elected.

    CONVERTIBLE PREFERRED STOCK: (CONTINUED)
    The holders of the preferred stock  are entitled to receive dividends  which
are  cumulative and in preference to  any common stock dividends, whenever funds
are legally  available  and when  declared  by the  Board  of Directors.  As  of
December  31, 1995, no dividends had been declared. The holders of the preferred
stock also have the  right of first  refusal to purchase a  portion of any  "new
securities,"  as defined in the stock purchase agreements, that may be issued by
the  Company.  In  addition,  the  preferred  stockholders  have  a  liquidation
preference  equal  to  $0.40 and  $1.00  per share  for  Series A  and  Series B
preferred stock, respectively,  plus all  declared and  unpaid dividends.  After
payment  of  the  liquidation  preference  to  the  preferred  stockholders, the
remaining assets of the Company will be distributed equally to the preferred and
common stockholder group as if all shares of preferred stock had been  converted
into  common stock. If the funds available  for distribution are not adequate to
cover the  preferred  stock  liquidation preference,  all  funds  available  for
distribution are to be distributed to the preferred stockholder ratably.
 
    STOCK OPTION PLAN:
 
    In  April 1993, the Company authorized the 1993 Stock Option Plan (the Plan)
under which the Board of Directors  may issue incentive stock options and  stock
bonuses  to employees and consultants of the Company. The Board of Directors has
the authority to  determine to  whom options and  bonuses will  be granted,  the
number  of shares, the  term and the  exercise price. Options  granted under the
Plan generally vest  over a four  year period at  the rate of  25% on the  first
anniversary  of employment and  1/48th each month  thereafter. In November 1995,
the Board  amended  the  Plan such  that  options  granted under  the  Plan  are
immediately  exercisable.  Unvested  stock issued  through  option  exercise are
subject to the Company's right of repurchase at the original exercise price. The
Company's right  of repurchase  decreases  as the  options  vest. The  right  of
exercise  generally expires  ten years  from the date  of grant  and the Company
holds the right of first refusal with  respect to shares issued pursuant to  the
exercise of options.
 
    Activity under the Plan is as follows:

5.  STOCKHOLDERS' EQUITY: (CONTINUED)
 
    STOCK OPTION PLAN: (CONTINUED)
    At  December 31, 1995, 2,118 shares  outstanding were subject to repurchase,
and approximately 2,442 outstanding  options would be  subject to repurchase  by
the Company if exercised.
 
6.  RELATED PARTIES:
    In  connection with its  incorporation, the Company  entered into a Business
Agreement with three of its  shareholders, EURODEC, SAGEM and SAT  (collectively
referred to as the Parties). Under the terms of the agreement, EURODEC and SAGEM
have  the  option to  develop, manufacture  and sell  products developed  by the
Company.
 
   
    Provided that  all  applicable  critical performance  milestones  have  been
satisfied,  SAGEM is required to pay the Company for the development of products
not to exceed the  amount set forth  in the budget agreed  upon by the  Parties.
During  1994 and 1995, the Company recognized $3,820 and $9,060 respectively, as
a result  of this  agreement.  Amounts recognized  have  been accounted  for  as
additional  paid-in capital in the  period that funding is  due according to the
agreement. At December  31, 1994 and  1995, $550  and $1,100 was  due under  the
agreement  but  had  not  received  and was  recognized  as  a  "receivable from
shareholder" within shareholders' equity.
    
 
    In addition, EURODEC and SAGEM are required to pay the Company a royalty fee
for each decoder  sold which incorporates  a licensed product.  The royalty  fee
will  be paid semiannually and based on the lesser of: 1.5% of the component and
direct manufacturing costs of EURODEC or  SAGEM for the licensed product or  two
dollars  for  each of  the first  5,000 decoders  sold and  one dollar  for each
decoder sold in excess of the first 5,000. The term of the Business Agreement is
for ten years unless terminated by either party upon failure of the other  party
to fulfill any of its obligations by issuance of a written notice.
 
    The  Company  and  C-Cube, a  stockholder,  entered into  a  Development and
Requirements Agreement. Following this agreement between the Company and C-Cube,
in connection with the issuance of common stock to C-Cube, C-Cube is required to
provide the Company  with intellectual  property rights  including source  codes
which  will  allow  the  Company to  develop  products  using  C-Cube integrated
circuits. The Company  has committed  to the purchase  of designated  integrated
circuits primarily from C-Cube under agreed upon requirements including C-Cube's
commitment  to  meet  certain critical  performance  milestones  and competitive
prices. In addition, the Company has  the right to repurchase the common  shares
in  the event that C-Cube fails to meet these milestones The initial term of the
agreement between the Company  and C-Cube is for  five years with provisions  to
consider  revisions to the agreement after the  third year of the signing of the
agreement. The agreement may be terminated  by either party upon failure of  the
other party to fulfill any of its obligations by issuance of a written notice.
 
    The  Company  entered into  a  Marketing Development  Agreement  with C-Cube
whereby the Company  assisted C-Cube in  the development and  marketing an  MPEG
Remultiplexer  chip. Under this agreement C-Cube paid the Company a nonrecurring
engineering fee and will also  pay a royalty for  each chip delivered to  C-Cube
customers. Royalties in the amount of none and $15 were earned in 1994 and 1995,
respectively.

</TABLE>
 
    The Company considers that  the realizability of the  deferred tax asset  is
more  likely than not based on the Company's future prospects, and the potential
to carryback any future losses.
 
    The Tax Reform  Act of 1986  limits the use  of net operating  loss and  tax
credit  carryforwards in  certain situations  where changes  occur in  the stock
ownership of  a company.  If the  Company should  have an  ownership change,  as
defined  in the Internal Revenue Code, utilization of the carryforwards could be
restricted.
 
    The benefit from income taxes is as follows for the year ended December  31,
1995.

8.  EMPLOYEE BENEFIT PLAN:
    The Company maintains  a 401(k)  profit-sharing plan  to provide  retirement
benefits  through  tax deferred  salary  deductions for  all  eligible employees
meeting certain age and service requirements. The Company may make discretionary
matching contributions on  behalf of employees.  All employee contributions  are
100% vested. The Company contributed $168 in 1995. No contributions were made in
1994.
 
9.  LINE OF CREDIT:
    In  January  1995,  the Company  entered  into  a revolving  line  of credit
agreement with a bank in the amount  of $5,000, expiring in January 1996.  Under
the  terms of the  agreement, advances are  limited to 75%  of eligible accounts
receivable; and  the  Company  must  comply with  several  financial  and  other
restrictive  covenants. The line  bears interest at  a rate of  prime plus 1% (a
total of 8.5% at December 31,  1995), and is collateralized by various  tangible
and  intangible present  and future  assets held by  the Company.  There were no
amounts due on the line of credit as of December 31, 1995.
 
10. SUBSEQUENT EVENT:
    In February 1996, the Company renewed its line of credit (see note 9  above)
in  the amount  of $15,000.  The line  will expire  in February  1997, and bears
interest in the amount of prime plus 1%, with the option of a reduction to prime
upon the Company's obtaining $8,000 in additional equity. The limit on  advances
is  based on 80% of  eligible accounts receivable and  50% of inventory. As with
the previous line, the  Company will be subject  to various financial and  other
covenants;  and the balance on the line will be collateralized by various assets
held by the Company.
 
   
    In May 1996, the Board of Directors approved the 1996 Stock Plan (the "Stock
Plan"). The Stock Plan provides for the  issuance of up to a maximum of  200,000
shares  of common stock pursuant to awards under the Stock Plan. The Company has
reserved 200,000 shares of common stock for issuance under the Stock Plan.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
   
    This  AMENDED  AND  RESTATED  AGREEMENT  AND  PLAN  OF  REORGANIZATION (this
"AGREEMENT") was made and entered into as of May 28, 1996 and amended as of July
  , 1996  among C-Cube  Microsystems Inc.,  a Delaware  corporation  ("PARENT"),
C-Cube  Acquisition Corp., a Delaware  corporation and a wholly-owned subsidiary
of Parent ("MERGER SUB")  DiviCom Inc., a  Delaware corporation (the  "COMPANY")
and Sagem S.A., Sagem International and Tregor Electronique S.A., each a company
organized  under  the laws  of France,  and Iena  International S.A.,  a company
organized under the laws of Luxembourg (collectively, "SELLER").
    
 
                                    RECITALS
 
    A.  The Boards of  Directors of each of the  Company, Parent and Merger  Sub
believe  it  is in  the  best interests  of  each company  and  their respective
stockholders that Parent acquire the Company through the statutory merger of the
Company with and  into Merger Sub  (the "MERGER") and,  in furtherance  thereof,
have approved the Merger.
 
    B.  Pursuant to the Merger, among other things, and subject to the terms and
conditions  of  this Agreement,  all  of the  issued  and outstanding  shares of
capital stock  of the  Company  ("COMPANY CAPITAL  STOCK") and  all  outstanding
options  and other rights to acquire or  receive shares of Company Capital Stock
shall be converted into the right to receive an amount of cash from Parent and a
number of shares of Common Stock of Parent ("PARENT COMMON STOCK").
 
    C.  A portion of the number  of the shares of Parent Common Stock  otherwise
issuable  by Parent to Significant Stockholders (as defined below) in connection
with the Merger shall be placed in escrow by Parent, the release of which amount
shall be contingent upon certain events and conditions.
 
   
    D.   The Company,  Parent, Merger  Sub  and Seller  desire to  make  certain
representations  and  warranties and  other  agreements in  connection  with the
Merger.

representations set forth herein, and for other good and valuable consideration,
intending to be legally bound hereby, the parties agree as follows:
 
                                   ARTICLE I

promptly as practicable, but no later than five (5) business days, following the
satisfaction or waiver of the conditions set forth in Article VI, at the offices

Road,  Palo  Alto, California,  unless another  place  or time  is agreed  to by
Parent, Seller and the Company. The date upon which the Closing actually  occurs
is  herein  referred  to  as  the  "CLOSING  DATE."  On  the  Closing  Date, the
appropriate parties hereto shall cause the Merger to be consummated by filing  a
Certificate  of Merger (or like  instrument) with the Secretary  of State of the
State of Delaware (the "CERTIFICATE OF MERGER") in accordance with the  relevant
provisions  of applicable law (the time of  acceptance by the Secretary of State
of Delaware of such filing being referred to herein as the "EFFECTIVE TIME").
 
    1.3  EFFECT OF THE MERGER.  At the Effective Time, the effect of the  Merger
shall  be  as provided  in the  applicable provisions  of Delaware  Law. Without

    thereafter amended as provided by law and such Certificate of Incorporation;
    provided, however, that Article I of the Certificate of Incorporation of the
    Surviving  Corporation shall be amended to read as follows: "The name of the
    corporation is Divicom Inc."
 
        (b) The Bylaws  of Merger  Sub, as in  effect immediately  prior to  the
    Effective  Time,  shall be  the Bylaws  of  the Surviving  Corporation until

paid  by Parent (including Parent Common Stock  to be reserved for issuance upon
exercise of any of the  Company's options to be  assumed by Parent) in  exchange
for  the acquisition by Parent of all  outstanding Company Capital Stock and all
unexpired and unexercised options  and warrants or any  other rights to  acquire
Company  Capital Stock  shall not exceed  the Aggregate Cash  Amount, as defined
below, plus the Aggregate Share Number, as defined below. No adjustment shall be
made in the aggregate consideration to be paid in the Merger as a result of  any
cash  proceeds received by the Company from  the date hereof to the Closing Date
pursuant to  the exercise  of options  or warrants  to acquire  Company  Capital
Stock.  Subject  to  the terms  and  conditions  of this  Agreement,  as  of the
Effective Time, by virtue of  the Merger and without any  action on the part  of
Merger  Sub, the  Company or  the holder  of any  shares of  the Company Capital
Stock, the following shall occur:

    VII  hereof,  each share  of Company  Capital  Stock issued  and outstanding
    immediately prior to the Effective Time other than any Dissenting Shares (as
    defined and to the extent provided  in Section 1.7(a)) will be canceled  and
    extinguished  and be converted automatically into  the right to receive upon
    surrender of  the certificate  representing such  share of  Company  Capital
    Stock in the manner provided in Section 1.8, without interest:
 
           (i)  for each share of Company Capital Stock that is not subject to a
       right of repurchase at  original purchase price  (a "VESTED SHARE",  with
       the  opposite: being  referred to  herein as  an "UNVESTED  SHARE"), that
       number of shares  of Parent  Common Stock  equal to  the Vested  Exchange
       Ratio,  as defined below,  and cash in  the amount of  the Per-Share Cash
       Payment, as defined below; or
 
           (ii) for each unvested share of Company Capital Stock, that number of
       shares of Parent Common  Stock equal to the  Unvested Exchange Ratio,  as
       defined below.
 
        (b)  TREATMENT OF STOCK OPTIONS.
 
           (i)  At the Effective Time, each option to purchase shares of Company
       Common Stock  (each,  a  "COMPANY OPTION")  then  outstanding  under  the
       Company's  1993 Stock Option Plan or the Company's 1996 Stock Option Plan
       (collectively, the "OPTION PLANS"), to the extent such Company Option  is
       unvested,  shall be,  in connection with  the Merger,  assumed by Parent.
       Each Company  Option so  assumed  by Parent  under this  Agreement  shall
       continue to
 
                                      A-2
<PAGE>
       have,  and be subject to, the same  terms and conditions set forth in the
       related  Option  Plan  and/or  as  provided  in  the  respective   option
       agreements  governing  such  Company  Option  immediately  prior  to  the
       Effective Time, except that (A) such Company Option shall be  exercisable
       for  that number  of whole  shares of  Parent Common  Stock equal  to the
       product of  the  number of  shares  of  Company Common  Stock  that  were
       issuable  upon exercise of  such Company Option  immediately prior to the
       Effective Time multiplied by the Unvested Exchange Ratio, rounded to  the
       nearest  whole number of  shares of Parent  Common Stock and  (B) the per
       share exercise price for the shares of Parent Common Stock issuable  upon
       exercise  of such assumed  Company Option shall be  equal to the quotient
       determined by dividing  the exercise  price per share  of Company  Common
       Stock  at which such Company Option  was exercisable immediately prior to
       the Effective Time by  the Unvested Exchange Ratio,  rounded down to  the
       nearest whole cent.
 
           (ii) Parent is not assuming Company Options that are vested as of the
       Effective  Time, nor is  Parent substituting its  options for such vested
       Company Options. As a result, each such vested Option shall terminate and
       cease to  be outstanding  as of  the Effective  Time to  the extent  such
       option is not exercised on or before the Effective Time.
 
          (iii)  It is  the intention  of the  parties that  the Company Options
       assumed by Parent qualify following the Effective Time as incentive stock
       options as defined in Section 422 of  the Code to the extent the  Company
       Options  qualified as  incentive stock  options immediately  prior to the
       Effective Time.
 
          (iv) Promptly following the Effective Time, Parent will issue to  each
       holder  of an outstanding  unvested Company Option  a document evidencing
       the foregoing assumption of the  unvested portion of such Company  Option
       by Parent.
 
        (c)   CAPITAL STOCK OF MERGER SUB.  Each share of Common Stock of Merger
    Sub issued and  outstanding immediately  prior to the  Effective Time  shall
    remain  one validly  issued, fully  paid and  nonassessable share  of Common
    Stock of the Surviving Corporation and each stock certificate of Merger  Sub
    shall  evidence ownership of  such shares of capital  stock of the Surviving
    Corporation.
 
        (d)  ADJUSTMENTS TO  EXCHANGE RATIOS.  The  Unvested Exchange Ratio  and
    the  Vested Exchange Ratio  (collectively, the "EXCHANGE  RATIOS"), shall be
    adjusted proportionally  to reflect  fully the  effect of  any stock  split,
    reverse  split, stock  dividend (including  any dividend  or distribution of
    securities convertible into Parent Common  Stock or Company Capital  Stock),
    reorganization, recapitalization or other like change with respect to Parent
    Common  Stock or Company  Capital Stock occurring after  the date hereof and
    prior to the Effective Time.
 
        (e)  FRACTIONAL SHARES.  No fraction  of a share of Parent Common  Stock
    will  be  issued, but  in lieu  thereof,  each holder  of shares  of Company
    Capital Stock who would otherwise  be entitled to a  fraction of a share  of
    Parent  Common  Stock (after  aggregating  all fractional  shares  of Parent
    Common Stock to  be received by  such holder) shall  be entitled to  receive
    from  Parent an amount of cash (rounded  to the nearest whole cent) equal to
    the product  of (i)  such  fraction, multiplied  by  the Average  Price,  as
    defined below.
 
   
        (f)  DEFINITIONS.
    
 
   
           (i) "AGGREGATE CASH AMOUNT" means $70,000,000.
    
 
   
           (ii)  "AGGREGATE  SHARE NUMBER"  means the  quotient (rounded  to the
       nearest share) obtained by dividing  (i) $130,000,000 by (ii) the  lesser
       of  (x) $53.89 (which would result in a quotient of 2,412,321 shares) and
       (y) the average of the closing prices  of a share of Parent Common  Stock
       on  the Nasdaq  National Market, or  the national  securities exchange on
       which Parent's Common Stock is then  traded, for the twelve (12)  trading
       days  immediately preceding the date of the Company's stockholder meeting
       (the "Company Meeting") at which the
    
 
                                      A-3
<PAGE>
   
       Merger and  the other  transactions contemplated  by this  Agreement  are
       submitted  for approval (the "Average Price"); provided, however, that if
       the quotient obtained thereby is greater than  2,680,412                ,
       the  quotient  shall be  deemed  to be  2,680,412                       .
       Notwithstanding anything  herein to  the contrary,  additional shares  of
       Parent  Common Stock  shall be  issuable in  connection with  payments to
       holders of unvested  Company Options  and unvested  Company Common  Stock
       pursuant to the Unvested Exchange Ratio.

       Capital  Stock outstanding immediately  prior to the  Effective Time that
       are held by "Non-Electing Stockholders" (as defined below). To  determine
       cash paid to a particular stockholder, the Per Share Cash Amount shall be
       multiplied  by  the  number  of  Vested  Shares  held  by  a Non-Electing
       Stockholder and then rounded to the nearest whole cent.
    
 
   
          (iv) "PRICE PER DIVICOM SHARE" means the quotient obtained by dividing
       (a) the sum of (i) the Aggregate Cash Amount and (ii) the product of  the
       Aggregate   Share  Number  multiplied  by   the  Average  Price,  by  (b)
       35,750,000.
    
 
   
           (v)  "STOCK  PORTION   OF  PRICE"  means   the  amount  obtained   by

          (vii)  "UNVESTED  EXCHANGE  RATIO"  means  the  quotient  obtained  by
       dividing the Price Per DiviCom Share by the Average Price.
    
 
   
         (viii)  "NON-ELECTING  STOCKHOLDERS"  are  those  Company  stockholders
       holding vested shares of Company stock who did not submit to the Company,
       on or before the Company Meeting,  their written election to receive  the
       Unvested Exchange Ratio with respect to those Vested Shares.
    
 
    1.7  DISSENTING SHARES.
 
        (a) Notwithstanding any provision of this Agreement to the contrary, any
    shares  of  Company Capital  Stock held  by  a holder  who has  demanded and
    perfected appraisal or dissenters' rights for such shares in accordance with
    Delaware Law  and  who,  as  of the  Effective  Time,  has  not  effectively
    withdrawn   or  lost  such  appraisal  or  dissenters'  rights  ("DISSENTING
    SHARES"), shall not be  converted into or represent  a right to receive  the
    Merger  consideration pursuant to Section 1.6,  but the holder thereof shall
    only be entitled to such rights as are granted by Delaware Law.
 
        (b) Notwithstanding the provisions of  subsection (a), if any holder  of
    shares  of Company Capital Stock who  demands appraisal of such shares under
    Delaware Law shall effectively withdraw or lose (through failure to  perfect
    or otherwise) the right to appraisal, then, as of the later of the Effective
    Time   and  the  occurrence  of  such  event,  such  holder's  shares  shall
    automatically be converted into and represent only the right to receive  the
    Merger  consideration as provided in  Section 1.6, without interest thereon,
    upon surrender of the certificate representing such shares.
 
        (c) The  Company shall  give Parent  (i) prompt  notice of  any  written
    demands for appraisal of any shares of Company Capital Stock, withdrawals of
    such  demands, and any other instruments served pursuant to Delaware Law and
    received by  the Company  and (ii)  the opportunity  to participate  in  all
    negotiations and proceedings with respect to such demands for appraisal. The
    Company  shall  not,  except  with  the  prior  written  consent  of Parent,
    voluntarily make any payment  with respect to any  demands for appraisal  of
    capital stock of the Company or offer to settle or settle any such demands.
 
                                      A-4
<PAGE>
        (d)  The Company  shall be solely  responsible for all  payments made in
    respect of Dissenting Shares and all related expenses, including  attorneys'
    fees,  and such  liability will  be automatically  assumed by  the Surviving
    Corporation.
 
    1.8  SURRENDER OF CERTIFICATES.
 
   
        (a)   EXCHANGE  AGENT.    Prior to  the  Effective  Time,  Parent  shall
    designate  Boston Equiserve to act as  exchange agent or appoint an employee
    or employees of the Parent to act in the capacity of the exchange agent  and
    escrow agent (as applicable, the "EXCHANGE AGENT" and the "ESCROW AGENT") in
    the Merger.
    
 
        (b)   PARENT TO  PROVIDE MERGER CONSIDERATION.   On the  business day in
    which the  Effective  Time occurs  as  to the  cash  portion of  the  Merger
    consideration,  and promptly  after the  Effective Time  as to  the non-cash
    portion of  the Merger  consideration, Parent  shall make  available to  the
    Exchange Agent for exchange in accordance with this Article I, the aggregate
    Merger  consideration  payable  pursuant  to  Section  1.6  in  exchange for
    outstanding shares of Company Capital Stock; provided that, on behalf of the
    Significant Stockholders, Parent shall withhold  and deposit into an  escrow
    account  a  number of  shares of  Parent Common  Stock equal  to 10%  of the
    aggregate number  of shares  of  Parent Common  Stock otherwise  payable  to
    holders  of at  least 1% of  the total  number of shares  of Company Capital
    Stock outstanding  immediately  prior  to  the Effective  Time  on  a  fully
    diluted,  as if converted to Common Stock  basis with respect to all options
    to acquire  such  stock (collectively,  the  "ESCROW AMOUNT").  Parent  will
    deduct  and deposit with the Escrow Agent  the Escrow Amount solely from the
    aggregate  Merger   consideration   payable  to   such   stockholders   (the
    "SIGNIFICANT  STOCKHOLDERS"). The portion of  the Escrow Amount withheld and
    deposited into escrow on behalf of a Significant Stockholder shall be  equal
    to  10%  of the  number of  shares that  such Significant  Stockholder would
    otherwise be entitled to receive under Section 1.6. No portion of the Escrow
    Amount shall be contributed in respect  of any Company Options or on  behalf
    of   any  holder  of  Company  Capital  Stock  that  is  not  a  Significant
    Stockholder.
 
        (c)  EXCHANGE PROCEDURES.
 
           (i) Prior to the Effective Time,  Parent shall cause to be  delivered
       to  each holder of  record of a  Certificate (i) a  letter of transmittal
       (which shall specify that  delivery shall be effected,  and risk of  loss
       and  title  to the  Certificates shall  pass, only  upon delivery  of the
       Certificates to the  Exchange Agent and  shall be in  such form and  have
       such  other  provisions  as  Parent  may  reasonably  specify),  and (ii)
       instructions  for  use  in  effecting  the  surrender  of  such  holder's
       certificate  or certificates (the "CERTIFICATES") which immediately prior
       to the Effective Time represented  outstanding shares of Company  Capital
       Stock  in  exchange for  the Merger  consideration.  Upon surrender  of a
       Certificate for cancellation to the Exchange Agent or to such other agent
       or agents as  may be appointed  by Parent, together  with such letter  of
       transmittal,  duly completed and validly  executed in accordance with the
       instructions thereto,  at the  Closing, the  holder of  such  Certificate
       shall  be entitled to  receive in exchange therefor,  the cash portion of
       the Merger consideration at the Closing  and the non-cash portion of  the
       Merger   consideration  promptly   thereafter  (subject   to  the  escrow
       provisions set  forth  in Article  VII  hereof),  plus cash  in  lieu  of
       fractional shares in accordance with Section 1.6, to which such holder is
       entitled  pursuant  to Section  1.6, and  the Certificate  so surrendered
       shall  forthwith  be  canceled.  Payments  of  cash  to  Seller  and  the
       Significant Stockholders pursuant to this Section 1.8(c)(i) shall be made
       by wire transfer of same day funds to accounts notified by them to Parent
       not less than 2 business days prior to the Effective Time.
 
           (ii)  As soon as practicable after the Effective Time, and subject to
       and in accordance with the provisions of Article VII hereof, Parent shall
       cause to be distributed to the  Escrow Agent (as defined in Article  VII)
       that  portion of the Merger consideration equal to the Escrow Amount. Any
       shares of  Parent  Common  Stock  held  by  the  Escrow  Agent  shall  be
       registered  in the  name of  the Escrow  Agent and  such shares  shall be
       beneficially owned by the holders on
 
                                      A-5
<PAGE>
       whose behalf such shares were deposited  in the Escrow Fund and shall  be
       available  to  compensate Parent  as provided  in  Article VII.  Until so
       surrendered, each outstanding  Certificate that, prior  to the  Effective
       Time, represented shares of Company Capital Stock will be deemed from and
       after  the Effective  Time, for  all corporate  purposes, other  than the
       payment of dividends, to  evidence only the right  to receive the  Merger
       consideration  in  respect  of each  such  share (subject  to  the escrow
       provisions set forth in Article VII hereof).
 
        (d)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.  No dividends  or
    other  distributions declared or made after  the Effective Time with respect
    to Parent Common Stock with a record  date after the Effective Time will  be
    paid  to the  holder of  any unsurrendered  Certificate with  respect to the
    shares of Parent Common Stock represented thereby until the holder of record
    of such Certificate shall surrender such Certificate. Subject to  applicable
    law, following surrender of any such Certificate, there shall be paid to the
    record holder of the certificates representing whole shares of Parent Common
    Stock  issued in  exchange therefor, without  interest, at the  time of such
    surrender, the  amount of  dividends (including  stock dividends)  or  other
    distributions  with a record date after  the Effective Time theretofore paid
    with respect to such whole shares of Parent Common Stock.
 
        (e)  TRANSFERS OF  OWNERSHIP.  If any  certificate for shares of  Parent
    Common  Stock  is to  be  issued in  a  name other  than  that in  which the
    Certificate surrendered in exchange therefor is registered or if any payment
    is to  be  made  to a  person  other  than that  in  which  the  Certificate
    surrendered  in exchange therefor  is registered, it will  be a condition of
    the issuance or payment thereof that the Certificate so surrendered will  be
    properly  endorsed and  otherwise in proper  form for transfer  and that the
    person requesting such exchange or payment  will have paid to Parent or  any
    agent designated by it any transfer or other taxes required by reason of the
    issuance  of a  certificate for  shares of Parent  Common Stock  in any name
    other than that of the registered holder of the Certificate surrendered,  or
    established to the satisfaction of Parent or any agent designated by it that
    such tax has been paid or is not payable.
 
        (f)   PAYMENTS  WITH RESPECT TO  UNEXCHANGED SHARES.   No interest shall
    accrue or be payable with respect to the Merger consideration payable on any
    unexchanged shares of Company Capital Stock.
 
        (g)  NO  LIABILITY.  Notwithstanding  anything to the  contrary in  this
    Section  1.8, none of  the Exchange Agent, the  Surviving Corporation or any
    party hereto shall be liable to a holder of shares of Parent Common Stock or
    Company Capital Stock  for any  amount properly  paid to  a public  official
    pursuant to any applicable abandoned property, escheat or similar law.
 
    1.9   NO FURTHER OWNERSHIP RIGHTS IN COMPANY COMMON STOCK.  All amounts paid
upon the surrender for exchange of shares of Company Capital Stock in accordance
with the terms hereof shall be deemed  to have been issued in full  satisfaction
of  all rights  pertaining to  such shares of  Company Capital  Stock, and there
shall be no further  registration of transfers on  the records of the  Surviving
Corporation   of  shares  of  Company   Capital  Stock  which  were  outstanding
immediately  prior  to  the  Effective  Time.  If,  after  the  Effective  Time,
Certificates  are presented  to the Surviving  Corporation for  any reason, they
shall be canceled and the Merger consideration shall be delivered to the  person
entitled  thereto (subject  to the  escrow provisions  set forth  in Article VII
hereof).
 
    1.10  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any Certificates
shall have been  lost, stolen or  destroyed, the Exchange  Agent shall issue  in
exchange  for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, such amount of cash and shares  of
Parent  Common  Stock, as  may be  required pursuant  to Section  1.6; provided,
however, that  Parent may,  in  its reasonable  discretion  and as  a  condition
precedent  to the issuance  thereof, require the  owner of such  lost, stolen or
destroyed Certificates  to deliver  a bond  in such  sum or  provide such  other
assurances  as it may reasonably direct as  indemnity against any claim that may
be made against Parent  or the Exchange Agent  with respect to the  Certificates
alleged to have been lost, stolen or destroyed.
 
                                      A-6
<PAGE>
    1.11   TAX  CONSEQUENCES.   It is  intended by  the parties  hereto that the
Merger shall constitute a  reorganization within the meaning  of Section 368  of
the  Internal Revenue Code  of 1986, as amended  (the "CODE"). Concurrently with
the execution of this agreement, counsel to Parent and the Company have provided
assurances satisfactory  to  Parent and  the  Company  to the  effect  that,  as
currently structured, the Merger will constitute such a reorganization.
 
    1.12  TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after the
Effective  Time, Parent or the  Surviving Corporation reasonably determines that
any  deeds,  assignments,  or  instruments  or  confirmations  of  transfer  are
necessary  or desirable to carry out the  purposes of this Agreement and to vest
the Surviving Corporation with full right,  title and possession to all  assets,
property,  rights, privileges, powers  and franchises of  the Company and Merger
Sub or to vest Parent  with a one hundred  percent (100%) ownership interest  in
the  Surviving Corporation or any  of its assets, the  officers and directors of
the Company and Merger Sub are fully authorized in the name of their  respective
corporations  or otherwise to take, and will take, all such lawful and necessary
or desirable action.
 
    1.13  AMENDMENT  OF COMPANY  CHARTER.   Immediately prior  to the  Effective
Time,  the Company will amend its  Certificate of Incorporation to eliminate the
preferential rights, if any, of holders of Preferred Stock of the Company (i) to
receive Merger consideration and, (ii) as more fully described in Section 2.1(7)
of the Company Disclosure Letter.
 
                                   ARTICLE II
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
    The Company hereby represents and warrants to Parent and Merger Sub, subject
to such exceptions as  are disclosed by the  Company in the schedules  delivered
simultaneously  herewith  (the "COMPANY  SCHEDULES") and  dated  as of  the date
hereof:
 
    2.1   ORGANIZATION  OF THE  COMPANY.   The  Company  is a  corporation  duly
organized,  validly existing and in good standing under the laws of the State of
Delaware. The Company has the corporate power to own its properties and to carry
on its business  as now being  conducted. The  Company is duly  qualified to  do
business  and in good standing as a  foreign corporation in each jurisdiction in
which the failure to be so qualified would have a material adverse effect on the
business, assets (including intangible assets), financial condition, results  of
operations  or prospects of  the Company. The  Company has delivered  a true and
correct copy of its Certificate of Incorporation and Bylaws, each as amended  to
date, to Parent.
 
    2.2  COMPANY CAPITAL STRUCTURE.
 
        (a)  The authorized capital stock of  the Company consists of 35,750,000
    (to be promptly increased to 35,950,000)  shares of Common Stock, of  which,
    as  of  May  23, 1996,  11,062,558  shares  are issued  and  outstanding and
    21,288,000 of  authorized Preferred  Stock. The  authorized Preferred  Stock
    consists  of  15,788,000  shares  of  Series  A  Preferred  Stock,  of which
    15,788,000 shares are issued and outstanding and 5,500,000 shares of  Series
    B Preferred Stock, of which 5,500,000 shares are issued and outstanding. The
    Company  Capital Stock is held of record  by the persons, with the addresses
    of record and in the amounts  set forth on Schedule 2.2(a). All  outstanding
    shares  of Company Capital Stock are  duly authorized, validly issued, fully
    paid and  non-assessable and  not subject  to preemptive  rights created  by
    statute,  the Certificate of  Incorporation or Bylaws of  the Company or any
    agreement to which the Company is a party or by which it is bound.
 
        (b) The  Company has  reserved  13,289,999 shares  of Common  Stock  for
    issuance  to  employees and  consultants  pursuant to  the  Company's Option
    Plans, of  which  as  of  May  23, 1996  3,132,817  shares  are  subject  to
    outstanding,  unexercised options  and 266,625  shares remain  available for
    future grant (to  be promptly  increased by  200,000). The  Company has  not
    reserved   any  shares  of  Common  Stock  for  issuance  upon  exercise  of
    outstanding Company  Options  granted  outside the  Option  Plans.  Schedule
    2.2(b)    sets   forth    for   each   outstanding    Company   Option   the
 
                                      A-7
<PAGE>
    name of the holder of such option, the domicile address of such holder,  the
    number  of shares of Common Stock subject to such option, the exercise price
    of such  option and  the vesting  schedule for  such option,  including  the
    extent  vested to date and whether the exercisability of such option will be
    accelerated and become exercisable by the transactions contemplated by  this
    Agreement.  Except  for the  Company Options  described in  Schedule 2.2(b),
    there are no options, warrants, calls, rights, commitments or agreements  of
    any  character, written or oral, to which the Company is a party or by which
    it is bound obligating  the Company to issue,  deliver, sell, repurchase  or
    redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any
    shares  of the capital stock of the  Company. Except for the Company Options
    described in Schedule 2.2(b), there are no options, warrants, calls, rights,
    commitments or agreements of  any character, written or  oral, to which  the
    Company  is a party or by which it is bound obligating the Company to grant,
    extend, accelerate the vesting of, change  the price of, otherwise amend  or
    enter into any such option, warrant, call, right, commitment or agreement.
 
    2.3   SUBSIDIARIES.  Except  as disclosed in Schedule  2.3, the Company does
not have and has never had any subsidiaries or affiliated companies and does not
otherwise own and has never otherwise owned  any shares of capital stock or  any
interest  in,  or  control,  directly  or  indirectly,  any  other  corporation,
partnership, association, joint venture or other business entity.
 
    2.4  AUTHORITY.  Subject  only to the requisite  approval of the Merger  and
this  Agreement by  the Company's  stockholders, the  Company has  all requisite
corporate power and authority to enter into this Agreement and to consummate the
transactions  contemplated   hereby.  The   vote  required   of  the   Company's

<PAGE>
    delivery  of  this Agreement  by the  Company, and  the consummation  of the
    transactions contemplated hereby, will  neither cause the  Company to be  in
    violation  or default under  any such license,  sublicense or agreement, nor
    entitle any other  party to  any such  license, sublicense  or agreement  to
    terminate  or modify such license, sublicense  or agreement, nor require the

    have  been asserted  or are, to  the Company's knowledge,  threatened by any

    service  mark, trade secret or other proprietary right, (ii) against the use
    by the Company of any trademarks, service marks, trade names, trade secrets,

                                  ARTICLE VII
               SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ESCROW
 
    7.1  SURVIVAL OF  REPRESENTATIONS AND WARRANTIES.   The representations  and
warranties  of the  Company and  Seller in this  Agreement or  in any instrument
delivered pursuant to this  Agreement shall survive the  Merger for a period  of
270 days. Following the Effective Time, the remedies of Parent for breach of any
of  the foregoing shall be  solely as set forth  in Section 7.2. The Significant
Stockholders shall have no liability for  breach of any of the foregoing  except
to  the extent of then respective proportionate  interest in the Escrow Fund, as
defined below. Notwithstanding the foregoing, if the Merger is not  consummated,
the Company will not be liable for any breach of any representation or warranty.
The representations and warranties of Parent and Merger Sub in this Agreement or
in  any instrument delivered pursuant to this Agreement shall terminate upon the
Closing.
 
    7.2  ESCROW ARRANGEMENTS.
 
        (a)  ESCROW FUND.  At  the Effective Time, the Significant  Stockholders
    will  be deemed  to have  received and deposited  with the  Escrow Agent the
    Escrow Amount (plus any  additional shares as may  be issued upon any  stock
    split,  stock  dividend or  recapitalization  effected by  Parent  after the
    Effective Time) without any act of  any stockholder. As soon as  practicable
    after  the  Effective  Time,  the  Escrow Amount,  without  any  act  of any
    stockholder, will  be  deposited with  the  Escrow Agent,  such  deposit  to
    constitute  an escrow fund (the  "ESCROW FUND") to be  governed by the terms
    set forth herein and at Parent's cost and expense. The Escrow Fund shall  be
    available  to compensate Parent  and its affiliates  for any claims, losses,
    liabilities, damages,  costs and  expenses,  including attorneys'  fees  and
    expenses,   and   expenses   of  investigation   and   defense  (hereinafter
    individually a "LOSS"  and collectively  "LOSSES") incurred  by Parent,  its
    officers,  directors, or affiliates (including the Surviving Corporation) as
    a result  of any  willful breach  of  a representation  or warranty  of  the
    Company  contained herein that, individually or in the aggregate, results in
    aggregate damage  to the  Company  and its  subsidiaries  of not  less  than
    $2,000,000.
 
        (b)      ESCROW  PERIOD;   DISTRIBUTION   UPON  TERMINATION   OF  ESCROW
    PERIODS.  Subject to the following requirements, the Escrow Fund shall be in
    existence immediately following  the Effective Time  and shall terminate  at
    5:00  p.m., California  time, on  the date which  is 270  days following the
    Closing (the "ESCROW PERIOD"); provided that  in the event a claim has  been
    made against the Escrow Fund prior to such time, the Escrow Agent shall only
    deliver  to the Significant Stockholders that  portion of the Escrow Fund as
    to which Parent and the Securityholders' Agents have
 
                                      A-29
<PAGE>
    agreed to the release. As  soon as all such  claims have been resolved,  the
    Escrow  Agent shall  deliver to  the Significant  Stockholders the remaining
    portion of the Escrow Fund not  required to satisfy such claims.  Deliveries
    of  Escrow Amounts to the Significant  Stockholders pursuant to this Section
    7.2(b)  shall  be   made  in   proportion  to   their  respective   original
    contributions to the Escrow Fund.
 
        (c)  PROTECTION OF ESCROW FUND.
 
           (i)  The Escrow Agent shall hold and safeguard the Escrow Fund during
       the Escrow Period, shall  treat such fund as  a trust fund in  accordance
       with  the terms of this  Agreement and not as  the property of Parent and
       shall hold and  dispose of the  Escrow Fund only  in accordance with  the
       terms hereof.
 
           (ii)  Any shares  of Parent Common  Stock or  other equity securities
       issued or distributed  by Parent  (including shares issued  upon a  stock
       split)  ("NEW SHARES") in  respect of, and any  cash dividends on, Parent
       Common Stock in  the Escrow Fund  which have not  been released from  the
       Escrow  Fund shall be added to the Escrow Fund and become a part thereof.
       New Shares issued  in respect of  shares of, and  any cash dividends  on,
       Parent  Common Stock which have been  released from the Escrow Fund shall
       not be added to the Escrow Fund,  but shall be distributed to the  record
       holders thereof.
 
          (iii)  Each stockholder shall  have voting rights  with respect to the
       shares of Parent Common Stock contributed to the Escrow Fund on behalf of
       such stockholder (and on any voting  securities added to the Escrow  Fund
       in  respect of such shares of Parent Common Stock) so long as such shares
       of Parent Common Stock or other voting securities are held in the  Escrow
       Fund.
 
        (d)  CLAIMS UPON ESCROW FUND.
 
           (i)  Upon receipt by  the Escrow Agent  at any time  on or before the
       last day of the Escrow Period of  a certificate signed by any officer  of
       Parent  (an "OFFICER'S CERTIFICATE"): (A) stating that Parent has paid or
       properly accrued or reasonably  anticipates that it will  have to pay  or
       accrue Losses, and (B) specifying in reasonable detail each Loss included
       in  the amount so  stated, the date  each such item  was paid or properly
       accrued, or the basis  for such anticipated Loss,  and the nature of  the
       willful  and  material  breach of  a  representation or  warranty  of the
       Company contained herein  (including the basis  for Parent's belief  that
       such  breach  is  willful),  the  Escrow  Agent  shall,  subject  to  the
       provisions of Section 7.2(e) hereof, deliver to Parent out of the  Escrow
       Fund, as promptly as practicable, such shares of Parent Common Stock, New
       Shares and/or cash held in the Escrow Fund then having an aggregate value
       equal to the amount of such Losses.
 
           (ii)  For the purposes of determining  the number of shares of Parent
       Common Stock to be delivered to Parent out of the Escrow Fund pursuant to
       Section 7.2(d)(i)  hereof, the  shares of  Parent Common  Stock shall  be
       valued  at the average of the closing  prices of Parent's Common Stock on
       the principal securities exchange on which Parent's Common Stock is  then
       traded, or if not so traded, the Nasdaq National Market System, in either
       case  as reported in THE WALL STREET JOURNAL for the five (5) consecutive
       trading days ending on the date that is two (2) trading days prior to the
       date such shares are delivered to  Parent out of the Escrow Fund.  Parent
       and  the Securityholder  Agents shall  certify that  such value  has been
       determined in accordance with this clause (ii) in a certificate signed by
       both Parent  and  the  Securityholder  Agents,  and  shall  deliver  such
       certificate to the Escrow Agent.
 
        (e)   OBJECTIONS TO  CLAIMS.  At  the time of  delivery of any Officer's
    Certificate to the Escrow Agent, a duplicate copy of such certificate  shall
    be  delivered to the Securityholder  Agents and for a  period of thirty (30)
    days after such delivery, the Escrow Agent shall make no delivery to  Parent
    of  any Escrow Amounts  pursuant to Section 7.2(d)  hereof unless the Escrow
    Agent shall  have received  written  authorization from  the  Securityholder
    Agents to make such delivery. After the
 
                                      A-30
<PAGE>
    expiration  of  such thirty  (30) day  period, the  Escrow Agent  shall make
    delivery of an amount from the Escrow Fund in accordance with Section 7.2(d)
    hereof, provided that no such payment or  delivery may be made if either  of
    the  Securityholder Agents shall object in  a written statement to the claim
    made in  the  Officer's Certificate,  and  such statement  shall  have  been
    delivered  to the Escrow Agent  prior to the expiration  of such thirty (30)
    day period.
 
        (f)  RESOLUTION OF CONFLICTS; ARBITRATION.
 
           (i) In case either  of the Securityholder Agents  shall so object  in
       writing  to any  claim or claims  made in any  Officer's Certificate, the
       Securityholder Agents and  Parent shall  attempt in good  faith to  agree
       upon  the rights of the  respective parties with respect  to each of such
       claims. If  the  Securityholder Agents  and  Parent should  so  agree,  a
       memorandum  setting forth such agreement shall  be prepared and signed by
       both parties and shall be furnished to the Escrow Agent. The Escrow Agent
       shall be entitled to rely on  any such memorandum and distribute  amounts
       from the Escrow Fund in accordance with the terms thereof.
 
           (ii)   If  no  such  agreement  can   be  reached  after  good  faith
       negotiation, either  Parent  or  the  Securityholder  Agents  may  demand
       arbitration  of the matter unless the amount  of the damage or loss is at
       issue  in  pending  litigation  with  a  third  party,  in  which   event
       arbitration  shall not be  commenced until such  amount is ascertained or
       both parties agree to  arbitration; and in either  such event the  matter
       shall  be settled by  arbitration conducted by  three arbitrators. Parent
       and the Securityholder Agents shall  each select one arbitrator, and  the
       two  arbitrators so  selected shall  select a  third arbitrator,  each of
       which arbitrators  shall  be independent  and  have at  least  ten  years
       relevant  experience. The arbitrators shall set a limited time period and
       establish procedures designed to reduce  the cost and time for  discovery
       while  allowing the parties an opportunity, adequate in the sole judgment
       of the arbitrators,  to discover relevant  information from the  opposing
       parties  about the subject  matter of the  dispute. The arbitrators shall
       rule upon  motions  to compel  or  limit  discovery and  shall  have  the
       authority to impose sanctions, including attorneys fees and costs, to the
       extent  as a  court of  competent law  or equity,  should the arbitrators
       determine that discovery was sought without substantial justification  or
       that   discovery  was   refused  or   objected  to   without  substantial
       justification. The decision of a majority of the three arbitrators as  to
       the  validity and amount of any claim in such Officer's Certificate shall
       be binding  and  conclusive  upon  the parties  to  this  Agreement,  and
       notwithstanding anything in Section 7.2(e) hereof, the Escrow Agent shall
       be  entitled to act in accordance with such decision and make or withhold
       payments out of the  Escrow Fund in  accordance therewith. Such  decision
       shall  be written and shall be supported  by written findings of fact and
       conclusions which shall set  forth the award,  judgment, decree or  order
       awarded by the arbitrators.
 
           (iii)  Judgment upon  any award  rendered by  the arbitrators  may be
       entered in any court having  jurisdiction. Any such arbitration shall  be
       held  in Santa Clara  County, California under the  rules of the American
       Arbitration Association  then in  effect. For  purposes of  this  Section
       7.2(f),  in any  arbitration hereunder in  which any claim  or the amount
       thereof stated in the Officer's Certificate is at issue, Parent shall  be
       deemed  to be the Non-Prevailing Party  in the event that the arbitrators
       award Parent less than the sum  of one-half (1/2) of the disputed  amount
       plus  any  amounts not  in dispute;  otherwise,  the stockholders  of the
       Company as represented by the Securityholder Agents shall be deemed to be
       the Non-Prevailing  Party. The  Non-Prevailing  Party to  an  arbitration
       shall   pay  its  own   expenses,  the  fees   of  each  arbitrator,  the
       administrative costs  of the  arbitration,  and the  expenses,  including
       without limitation, reasonable attorneys' fees and costs, incurred by the
       other party to the arbitration.
 
        (g)   SECURITYHOLDER  AGENTS OF  THE SIGNIFICANT  STOCKHOLDERS; POWER OF
    ATTORNEY.
 
           (i) In the  event that the  Merger is approved,  effective upon  such
       vote,  and without further  act of any stockholder,  Mr. Nolan Daines, on
       behalf of the Company, and Ms. Caroline
 
                                      A-31
<PAGE>
       de Puysegur, on  behalf of Seller,  shall be appointed  as co-agents  and
       attorneys-in-fact  (the "SECURITYHOLDER AGENTS") for and on behalf of the
       Significant Stockholders, to give and receive notices and communications,
       to authorize  delivery  to Parent  of  assets  from the  Escrow  Fund  in
       satisfaction  of claims by Parent, to object to such deliveries, to agree
       to, negotiate,  enter into  settlements and  compromises of,  and  demand
       arbitration  and comply with  orders of courts  and awards of arbitrators
       with respect  to  such claims,  and  to  take all  actions  necessary  or
       appropriate   in   the  judgment   of   Securityholder  Agents   for  the
       accomplishment of the foregoing. Such agency may be changed (i) as to Mr.
       Daines' position, by the vote or action of two-thirds in interest of  the
       Significant  Stockholders  other  than  Seller, and  (ii)  as  to  Ms. de
       Puysegur, by Seller from time to time, in either case upon not less  than
       thirty  (30)  days prior  written notice  to Parent.  Any vacancy  in the
       position of either  of the  Securityholder Agents  may be  filled by  the
       foregoing  procedures  as  to  the respective  agent.  No  bond  shall be
       required of  the Securityholder  Agents,  and the  Securityholder  Agents
       shall   not  receive   compensation  for   their  services.   Notices  or
       communications to  or from  the  Securityholder Agents  shall  constitute
       notice to or from each of the Significant Stockholders of the Company. In
       no  event  shall Parent  be  required to  resolve  any dispute  among the
       Securityholder Agents, who shall act jointly in all matters as to Parent,
       except that either of the Securityholder Agents may execute an  objection
       to  a claim by Parent (but the  Securityholder Agents will act jointly to
       resolve such dispute). As between the Securityholder Agents, all  actions
       will  be submitted to a simple  majority vote in which the representation
       of the Selling  Stockholders other  than Seller  will have  49 votes  and
       Seller's  representative will have 51  votes. Upon any reasonable request
       by Parent,  the  Securityholder Agents  will  undertake to  vote  upon  a
       matter.
 
           (ii)  The Securityholder Agents shall not  be liable for any act done
       or omitted hereunder as Securityholder Agents while acting in good  faith
       and in the exercise of reasonable judgment.
 
        (h)   ACTIONS OF THE SECURITYHOLDER AGENTS.  A decision, act, consent or
    instruction of the Securityholder Agents shall constitute a decision of  all
    the Significant Stockholders and shall be final, binding and conclusive upon
    each  of the Significant  Stockholders, and the Escrow  Agent and Parent may
    rely  upon  any  such   decision,  act,  consent   or  instruction  of   the
    Securityholder  Agents as being the decision, act, consent or instruction of
    each Significant  Stockholder.  The  Escrow  Agent  and  Parent  are  hereby
    relieved  from any  liability to  any person  for any  acts done  by them in
    accordance  with  such  decision,  act,   consent  or  instruction  of   the
    Securityholder Agents.
 
        (i)    THIRD-PARTY CLAIMS.    In the  event  Parent becomes  aware  of a
    third-party claim which Parent believes may  result in a demand against  the
    Escrow  Fund, Parent shall  notify the Securityholder  Agents of such claim,
    and the Securityholder Agents shall be entitled, at their expense, to assume
    and control any defense of  such claim. Parent may  not agree to settle  any
    such  claim without the prior written  consent of the Securityholder Agents,
    which  will  not   be  unreasonably   withheld.  In  the   event  that   the
    Securityholder  Agents have consented to  any such settlement, including the
    amount thereof, and acknowledged that the claim is a valid claim against the
    Escrow Fund, the Securityholder Agents shall  have no power or authority  to
    object under any provision of this Article VII to the amount of any claim by
    Parent against the Escrow Fund with respect to such settlement.
 
        (j)  ESCROW AGENT'S DUTIES.
 
           (i)  The Escrow Agent shall be  obligated only for the performance of
       such duties as are specifically set forth herein, and as set forth in any
       additional written escrow instructions which the Escrow Agent may receive
       after the date of this Agreement which are signed by an officer of Parent
       and the  Agent,  and  may rely  and  shall  be protected  in  relying  or
       refraining  from  acting  on  any instrument  reasonably  believed  to be
       genuine and  to have  been signed  or presented  by the  proper party  or
       parties.   The   Escrow  Agent   shall  not   be   liable  for   any  act
 
                                      A-32
<PAGE>
       done or omitted hereunder as Escrow Agent while acting in good faith  and
       in  the  exercise of  reasonable judgment,  and any  act done  or omitted
       pursuant to the advice  of counsel shall be  conclusive evidence of  such
       good faith.
 
           (ii)  The Escrow Agent is hereby  expressly authorized to comply with
       and obey orders, judgments  or decrees of any  court. In case the  Escrow
       Agent  obeys or complies with  any such order, judgment  or decree of any
       court, the Escrow Agent shall not be liable to any of the parties  hereto
       or  to any other person by reason of such compliance, notwithstanding any
       such order,  judgment or  decree being  subsequently reversed,  modified,
       annulled,  set  aside,  vacated or  found  to have  been  entered without
       jurisdiction.
 
           (iii) The Escrow Agent shall not be liable for the expiration of  any
       rights under any statute of limitations with respect to this Agreement or
       any documents deposited with the Escrow Agent.
 
           (iv)  In performing any duties under  the Agreement, the Escrow Agent
       shall not be liable to any party for damages, losses, or expenses, except
       for gross negligence  or willful  misconduct on  the part  of the  Escrow
       Agent.  The Escrow Agent shall  not incur any such  liability for (A) any
       act or failure to act  made or omitted in good  faith, or (B) any  action
       taken  or omitted in reliance upon  any instrument, including any written
       statement of affidavit  provided for  in this Agreement  that the  Escrow
       Agent  shall in  good faith  believe to be  genuine, nor  will the Escrow
       Agent be liable or responsible  for forgeries, fraud, impersonations,  or
       determining  the scope of any  representative authority. In addition, the
       Escrow Agent may consult with the legal counsel in connection with Escrow
       Agent's duties under this Agreement and  shall be fully protected in  any
       act  taken, suffered, or permitted by him/her in good faith in accordance
       with the  advice of  counsel. The  Escrow Agent  is not  responsible  for
       determining   and  verifying  the  authority  of  any  person  acting  or
       purporting to act on behalf of any party to this Agreement.
 
           (v) If any controversy arises between the parties to this  Agreement,
       or with any other party, concerning the subject matter of this Agreement,
       its  terms  or  conditions, the  Escrow  Agent  will not  be  required to
       determine the controversy or to take any action regarding it. The  Escrow
       Agent  may hold all documents, cash and shares of Parent Common Stock and
       may wait  for settlement  of any  such controversy  by final  appropriate
       legal  proceedings or other  means as, in  the Escrow Agent's discretion,
       the Escrow Agent may be required, despite what may be set forth elsewhere
       in this Agreement. In such event, the Escrow Agent will not be liable for
       damage.
 
           Furthermore, the Escrow Agent  may at its option,  file an action  of
       interpleader  requiring the parties to answer and litigate any claims and
       rights among themselves. The Escrow  Agent is authorized to deposit  with
       the  clerk of the court  all documents, cash and  shares of Parent Common
       Stock held in escrow, except  all cost, expenses, charges and  reasonable
       attorney fees incurred by the Escrow Agent due to the interpleader action
       and which the Escrow Agent may recoup directly from the Escrow Fund. Upon
       initiating  such action,  the Escrow  Agent shall  be fully  released and
       discharged of and from all obligations and liability imposed by the terms
       of this Agreement.
 
           (vi) Parent and  its successors  and assigns agree  to indemnify  and
       hold  Escrow Agent harmless against any  and all losses, claims, damages,
       liabilities, and expenses, including  reasonable costs of  investigation,
       counsel  fees, and disbursements  that may be imposed  on Escrow Agent or
       incurred by Escrow Agent in connection with the performance of the Escrow
       Agent's duties under  this Agreement,  including but not  limited to  any
       litigation arising from this Agreement or involving its subject matter.
 
           (vii)  The Escrow Agent may  resign at any time  upon giving at least
       thirty (30) days written notice to Parent and the Securityholder  Agents;
       provided, however, that no such
 
                                      A-33
<PAGE>
       resignation  shall become effective until  the appointment of a successor
       escrow agent  which shall  be  accomplished as  follows: Parent  and  the
       Securityholder Agents shall use their best efforts to mutually agree on a
       successor  escrow  agent within  thirty  (30) days  after  receiving such
       notice. If the parties fail to agree upon a successor escrow agent within
       such time, Parent  shall have  the right  to appoint  a successor  escrow
       agent authorized to do business in the State of California. The successor
       escrow  agent  shall execute  and  deliver an  instrument  accepting such
       appointment and it shall,  without further acts, be  vested with all  the
       estates, properties, rights, powers, and duties of the predecessor escrow
       agent  as if originally named as escrow  agent. The Escrow Agent shall be
       discharged from any further duties and liability under this Agreement.
 
        (k)  FEES.  All fees of  the Escrow Agent for performance of its  duties
    hereunder  shall be paid by Parent. It is understood that the fees and usual
    charges agreed upon  for services of  the Escrow Agent  shall be  considered
    compensation for ordinary services as contemplated by this Agreement. In the
    event  that the conditions of this  Agreement are not promptly fulfilled, or
    if the Escrow Agent renders any service not provided for in this  Agreement,
    or  if  the parties  request a  substantial modification  of its  terms, the
    Escrow  Agent  shall  be  reasonably  compensated  for  such   extraordinary
    services. Parent promises to pay these sums upon demand.
 
                                  ARTICLE VIII
                       TERMINATION, AMENDMENT AND WAIVER
 
    8.1   TERMINATION.  Except as provided  in Section 8.2 below, this Agreement
may be terminated and the  Merger abandoned at any  time prior to the  Effective
Time:
 
        (a) by mutual consent of the Company, Seller and Parent;
 
        (b)  by Parent, Seller or the Company if: (i) the Effective Time has not
    occurred by  August 31,  1996 (provided  that the  right to  terminate  this
    Agreement  under this clause  8.1(b)(i) shall not be  available to any party
    whose willful failure to fulfill any obligation hereunder has been the cause
    of, or resulted in, the failure of the Effective Time to occur on or  before
    such  date); (ii) there shall be a final nonappealable order of a federal or
    state court in effect preventing consummation of the Merger; or (iii)  there
    shall  be any  statute, rule,  regulation or  order enacted,  promulgated or
    issued or deemed applicable  to the Merger by  any Governmental Entity  that
    would make consummation of the Merger illegal;
 
        (c)  by Parent if there shall be any action taken, or any statute, rule,
    regulation or order enacted, promulgated  or issued or deemed applicable  to
    the  Merger, by any Governmental Entity,  which would: (i) prohibit Parent's
    or the Company's ownership  or operation of any  portion of the business  of
    the  Company or  (ii) compel  Parent or  the Company  to dispose  of or hold
    separate, as a result of the Merger,  any portion of the business or  assets
    of the Company or Parent; in either case, the unavailability of which assets
    or  business would have an adverse effect on Parent's ability to realize the
    benefits expected from the Merger;
 
        (d) by Parent if it is not  in material breach of its obligations  under
    this  Agreement and there has been a breach of any representation, warranty,
    covenant or agreement contained in this Agreement on the part of the Company
    and as a result of such breach the conditions set forth in Section 6.3(a) or
    6.3(b), as the case may be, would not then be satisfied; provided,  however,
    that  if  such breach  is curable  by  the Company  within thirty  (30) days
    through the exercise of its reasonable best efforts, then for so long as the
    Company continues to exercise  such reasonable best  efforts Parent may  not
    terminate this Agreement under this Section 8.1(d) unless such breach is not
    cured  within thirty (30) days  (but no cure period  shall be required for a
    breach which by its nature cannot be cured);
 
                                      A-34
<PAGE>
        (e) by the Company if  it is not in  material breach of its  obligations
    under  this Agreement  and there  has been  a breach  of any representation,
    warranty, covenant or agreement contained in  this Agreement on the part  of
    Parent or Merger Sub and as a result of such breach the conditions set forth
    in  Section  6.2(a)  or  6.2(b), as  the  case  may be,  would  not  then be
    satisfied; provided, however, that  if such breach is  curable by Parent  or
    Merger  Sub within thirty  (30) days through the  exercise of its reasonable
    best efforts, then for so long as Parent or Merger Sub continues to exercise
    such reasonable best efforts  the Company may  not terminate this  Agreement
    under this Section 8.1(e) unless such breach is not cured within thirty (30)
    days  (but no cure period shall be required for a breach which by its nature
    cannot be cured); and
 
        (f) by Parent if the Company shall not have obtained the approval of its
    stockholders to  the  Merger  and  the  transactions  contemplated  by  this
    Agreement  by  thirty  days after  the  effective date  of  the Registration
    Statement.
 
    Where action is taken to terminate  this Agreement pursuant to this  Section
8.1,  it shall be  sufficient for such action  to be authorized  by the Board of
Directors (as applicable) of the party taking such action, but such  termination
shall  only be effective  upon delivery of  written notice to  the other parties
hereto.
 
    8.2  EFFECT OF TERMINATION.  In  the event of termination of this  Agreement
as provided in Section 8.1, this Agreement shall forthwith become void and there
shall  be no liability  or obligation on the  part of Parent,  Merger Sub or the
Company, or their respective officers, directors or stockholders, provided  that
each  party shall remain liable for any  breaches of this Agreement prior to its
termination; and provided further  that the provisions of  Sections 5.4 and  5.5
and  Article VIII of  this Agreement shall  remain in full  force and effect and
survive any termination of this Agreement.
 
    8.3  AMENDMENT.  Except as is otherwise required by applicable law after the
stockholders of  the  Company approve  this  Agreement, this  Agreement  may  be
amended  by the  parties hereto  at any  time by  execution of  an instrument in
writing signed on behalf of each of the parties hereto.
 
    8.4  EXTENSION; WAIVER.  At any time prior to the Effective Time, Parent and
Merger Sub, on the one hand, and the  Company and Seller, on the other, may,  to
the  extent legally allowed, (i)  extend the time for  the performance of any of
the obligations of the  other party hereto, (ii)  waive any inaccuracies in  the
representations  and warranties  made to such  party contained herein  or in any
document delivered pursuant hereto, and (iii)  waive compliance with any of  the
agreements  or conditions  for the benefit  of such party  contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set  forth in an  instrument in writing signed  on behalf of  such
party.
 
    8.5   NOTICE OF TERMINATION.  Any termination of the Agreement under Section
8.1 above will be effective immediately  upon the delivery of written notice  of
the terminating party to the other parties hereto.
 
                                   ARTICLE IX

    9.2  INTERPRETATION.  The  words "include," "includes" and "including"  when
used  herein shall be deemed  in each case to be  followed by the words "without
limitation." The word "agreement" when used herein shall be deemed in each  case
to  mean any contract,  commitment or other agreement,  whether oral or written,
that is legally binding.  The table of contents  and headings contained in  this
Agreement  are for reference purposes  only and shall not  affect in any way the
meaning  or  interpretation  of  this  Agreement.  Nothing  in  this  agreement,
including  in  respect of  Section 4.1,  shall be  interpreted to  eliminate any
existing restrictions upon the  authority of the officers  of the Company or  to
limit  the authority of the Company's board of directors to impose or alter such
restrictions from time to time.
 
    9.3   COUNTERPARTS.    This  Agreement  may  be  executed  in  one  or  more
counterparts,  all of which shall  be considered one and  the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties  and delivered  to the  other party,  it being  understood that  all
parties need not sign the same counterpart.
 
    9.4    ENTIRE  AGREEMENT; ASSIGNMENT.    This Agreement,  the  schedules and
Exhibits hereto, and the  documents and instruments  and other agreements  among
the  parties hereto referenced herein: (a) constitute the entire agreement among
the parties with respect  to the subject matter  hereof and supersede all  prior
agreements  and understandings,  both written and  oral, among  the parties with
respect to the subject matter  hereof; (b) are not  intended to confer upon  any
other  person any rights or remedies hereunder; and (c) shall not be assigned by
operation of law or otherwise except as otherwise specifically provided.
 
    9.5  SEVERABILITY.  In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be  illegal, void  or unenforceable,  the remainder  of this  Agreement  will
continue in full force and effect and the application of such provision to other
persons  or circumstances  will be  interpreted so  as reasonably  to effect the
intent of the parties hereto. The parties further agree to replace such void  or
unenforceable provision of this Agreement with a valid and enforceable provision
that  will achieve,  to the  extent possible,  the economic,  business and other
purposes of such void or unenforceable provision.
 
                                      A-37
<PAGE>
    9.6   OTHER REMEDIES.   Except  as otherwise  provided herein,  any and  all
remedies  herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party, and the exercise by a party of any one remedy will not preclude  the
exercise of any other remedy.
 
    9.7    GOVERNING  LAW; VENUE.    This  Agreement shall  be  governed  by and
construed in accordance with the laws of the State of California, regardless  of
the laws that might otherwise govern under applicable principles of conflicts of
laws  thereof. Each of the parties hereto agrees that process may be served upon
them in any manner authorized  by the laws of the  State of California for  such
persons and waives and covenants not to assert or plead any objection which they
might  otherwise  have to  such  jurisdiction and  such  process. Any  action in
connection with this  Agreement shall  be brought  in the  appropriate state  or
Federal  courts in Santa  Clara County, California;  PROVIDED, HOWEVER, that any
dispute under Article VII hereof shall be subject to the arbitration provisions.
 
    9.8  RULES OF CONSTRUCTION.   The parties hereto  agree that they have  been
represented  by counsel during  the negotiation and  execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction providing that ambiguities in  an agreement or other document  will
be construed against the party drafting such agreement or document.
 
   
    9.9  SPECIFIC PERFORMANCE.  The parties hereto agree that irreparable damage
would  occur in the event that any of  the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed  that the parties  shall be entitled  to an injunction  or
injunctions  to prevent breaches  of this Agreement  and to enforce specifically
the terms and provisions hereof in any  court of the United States or any  state
having  jurisdiction, this being in  addition to any other  remedy to which they
are entitled at law or in equity.

                        DELAWARE GENERAL CORPORATION LAW
                                APPRAISAL RIGHTS
 
    262 APPRAISAL RIGHTS. (a) Any stockholder of a corporation of this State who
holds  shares  of stock  on  the date  of  the making  of  a demand  pursuant to
subsection (d) of  this section with  respect to such  shares, who  continuously
holds such shares through the effective date of the merger or consolidation, who
has  otherwise complied with subsection (d) of  this section and who has neither
voted in favor of the merger  or consolidation nor consented thereto in  writing
pursuant  to Section 228 of this title shall  be entitled to an appraisal by the
Court of  Chancery  of  the  fair  value  of  his  shares  of  stock  under  the
circumstances  described in subsections (b) and (c)  of this section. As used in
this section, the  word "stockholder" means  a holder  of record of  stock in  a
stock  corporation and also  a member of  record of a  nonstock corporation; the
words "stock" and  "share" mean and  include what is  ordinarily meant by  those
words  and also  membership or  membership interest  of a  member of  a nonstock
corporation; and  the  words  "depository  receipt"  mean  a  receipt  or  other
instrument  issued  by a  depository  representing an  interest  in one  or more
shares, or fractions thereof, solely of  stock of a corporation, which stock  is
deposited with the depository.
 
    (b)  Appraisal rights  shall be  available for  the shares  of any  class or
series of stock of a constituent corporation in a merger or consolidation to  be
effected pursuant to Section 251, 252, 254, 257, 258, 263 or 264 of this title:
 
        (1) Provided, however, that no appraisal rights under this section shall
    be available for the shares of any class or series of stock, which stock, or
    depository  receipts  in  respect  thereof,  at  the  record  date  fixed to
    determine the stockholders entitled to receive notice of and to vote at  the
    meeting   of  stockholders  to  act  upon  the  agreement  of  a  merger  or
    consolidation, were either (i) listed  on a national securities exchange  or
    designated as a national market systems security on an interdealer quotation
    system  by the National Association of Securities Dealers, Inc. or (ii) held
    of record by more than 2,000 holders; and further provided that no appraisal
    rights shall  be  available for  any  shares  of stock  of  the  constituent
    corporation  surviving  a  merger if  the  merger  did not  require  for its
    approval the vote of the holders of the surviving corporation as provided in
    (1) SUBSECTIONS (f) OR (g) of Section 251 of this title.
 
        (2) Notwithstanding paragraph (1)  of this subsection, appraisal  rights
    under  this section shall be available for the shares of any class or series
    of stock of a constituent corporation if the holders thereof are required by
    the terms of an  agreement of merger or  consolidation pursuant to  Sections
    251,  252, 254, 257, 258, 263 and 264 of this title to accept for such stock
    anything except:
 
           a.  Shares of  stock of the corporation  surviving or resulting  from
       such merger or consolidation, or depository receipts in respect thereof;
 
           b.   Shares of stock of any other corporation, or depository receipts
       in respect thereof, which shares of  stock or depository receipts at  the
       effective  date of the merger or consolidation will be either listed on a
       national securities exchange  or designated as  a national market  system
       security  on an interdealer quotation  system by the National Association
       of Securities Dealers, Inc. or held of record by more than 2,000 holders;
 
           c.   Cash  in lieu  of  fractional shares  or  fractional  depository
       receipts  described  in the  foregoing subparagraphs  a.  and b.  of this
       paragraph; or
 
           d.  Any combination of the shares of stock, depository receipts,  and
       cash  in  lieu of  fractional  shares or  fractional  depository receipts
       described in the foregoing subparagraphs a., b. and c. of this paragraph.
 
                                      B-1
<PAGE>
        (3) In the event all of  the stock of a subsidiary Delaware  corporation
    party  to a  merger effected  under 253 of  this title  is not  owned by the
    parent corporation immediately prior to  the merger, appraisal rights  shall
    be available for the shares of the subsidiary Delaware corporation.
 
    (c)  Any corporation  may provide in  its certificate  of incorporation that
appraisal rights under  this section shall  be available for  the shares of  any
class  or series of its stock as a  result of an amendment to its certificate of
incorporation, any  merger  or  consolidation  in which  the  corporation  is  a
constituent corporation or the sale of all or substantially all of the assets of
the  corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
    (d) Appraisal rights shall be perfected as follows:
 
        (1) If a proposed merger or consolidation for which appraisal rights are
    provided under this section is to be submitted for approval at a meeting  of
    stockholders,  the corporation, not less than  20 days prior to the meeting,
    shall notify each of its  stockholders who was such  on the record date  for
    such meeting with respect to shares for which appraisal rights are available
    pursuant  to  subsections  (b)  and (c)  hereof  that  appraisal  rights are
    available for any or all of the shares of the constituent corporations,  and
    shall  include  in such  notice  a copy  of  this section.  Each stockholder
    electing to  demand  the  appraisal  of his  shares  shall  deliver  to  the
    corporation, before the taking of the vote on the merger or consolidation, a
    written  demand for appraisal of his  shares. Such demand will be sufficient
    if it reasonably informs the corporation of the identity of the  stockholder
    and  that the  stockholder intends  thereby to  demand the  appraisal of his
    shares. A  proxy or  vote  against the  merger  or consolidation  shall  not
    constitute such a demand. A stockholder electing to take such action must do
    so by a separate written demand as herein provided. Within 10 days after the
    effective  date of such merger or  consolidation, the surviving or resulting
    corporation shall notify  each stockholder of  each constituent  corporation
    who  has complied  with this  subsection and  has not  voted in  favor of or
    consented to the  merger or  consolidation of the  date that  the merger  or
    consolidation has become effective; or
 
        (2)  If the merger or consolidation was approved pursuant to Section 228
    or 253 of this title, the surviving or resulting corporation, either  before
    the  effective  date  of  the  merger or  consolidation  or  within  10 days
    thereafter, shall  notify each  of the  stockholders entitled  to  appraisal
    rights  of  the  effective date  of  the  merger or  consolidation  and that
    appraisal rights  are  available  for  any  or all  of  the  shares  of  the
    constituent  corporation, and  shall include in  such notice a  copy of this
    section. The notice shall  be sent by certified  or registered mail,  return
    receipt requested, addressed to the stockholder at his address as it appears
    on  the records  of the corporation.  Any stockholder  entitled to appraisal
    rights may, within 20 days after the  date of mailing of the notice,  demand
    in  writing from the surviving or resulting corporation the appraisal of his
    shares. Such  demand  will  be  sufficient  if  it  reasonably  informs  the
    corporation  of the  identity of  the stockholder  and that  the stockholder
    intends thereby to demand the appraisal of his shares.
 
    (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied  with
subsections  (a)  and (d)  hereof  and who  is  otherwise entitled  to appraisal
rights, may file a petition in  the Court of Chancery demanding a  determination
of  the  value  of  the  stock of  all  such  stockholders.  Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger  or
consolidation,  any stockholder shall have the  right to withdraw his demand for
appraisal and to  accept the  terms offered  upon the  merger or  consolidation.
Within  120 days after  the effective date  of the merger  or consolidation, any
stockholder who has complied  with the requirements of  subsections (a) and  (d)
hereof,  upon written request, shall be entitled to receive from the corporation
surviving the merger  or resulting  from the consolidation  a statement  setting
forth  the  aggregate number  of  shares not  voted in  favor  of the  merger or
consolidation and with respect to which demands for appraisal have been received
and the aggregate number of holders of such shares. Such written statement shall
be mailed to the stockholder within 10 days after
 
                                      B-2
<PAGE>
his written  request  for such  a  statement is  received  by the  surviving  or
resulting  corporation  or within  10 days  after expiration  of the  period for
delivery of  demands for  appraisal under  subsection (d)  hereof, whichever  is
later.
 
    (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof  shall be made upon the  surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was  filed a duly verified  list containing the names  and
addresses  of all  stockholders who have  demanded payment for  their shares and
with whom agreements as to  the value of their shares  have not been reached  by
the  surviving or resulting corporation.  If the petition shall  be filed by the
surviving or resulting corporation, the petition shall be accompanied by such  a
duly  verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of  the time and  place fixed for  the hearing of  such petition  by
registered  or certified mail  to the surviving or  resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such  notice
shall also be given by one or more publications at least one week before the day
of  the hearing, in a newspaper of  general circulation published in the City of
Wilmington, Delaware or such publication as the Court deems advisable. The forms
of the notices by mail  and by publication shall be  approved by the Court,  and
the costs thereof shall be borne by the surviving or resulting corporation.
 
    (g)  At  the  hearing  on  such  petition,  the  Court  shall  determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court  may require the stockholders  who have demanded  an
appraisal  for their  shares and who  hold stock represented  by certificates to
submit their certificates  of stock  to the  Register in  Chancery for  notation
thereon  of the  pendency of the  appraisal proceedings; and  if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
    (h) After determining the stockholders entitled to any appraisal, the  Court
shall appraise the shares, determining their fair value exclusive of any element
of  value  arising  from the  accomplishment  or  expectation of  the  merger or
consolidation, together with a fair  rate of interest, if  any, to be paid  upon
the  amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate  of
interest  which the surviving or resulting corporation  would have had to pay to
borrow money during  the pendency  of the  proceeding. Upon  application by  the
surviving or resulting corporation or by any stockholder entitled to participate
in  the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal  prior
to  the final  determination of  the stockholder  entitled to  an appraisal. Any
stockholder whose name appears on the  list filed by the surviving or  resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates  of stock  to the  Register in Chancery,  if such  is required, may
participate fully in all proceedings until  it is finally determined that he  is
not entitled to appraisal rights under this section.
 
    (i)  The Court  shall direct the  payment of  the fair value  of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the  Court
may  direct. Payment shall be  so make to each such  stockholder, in the case of
holders of uncertificated  stock forthwith, and  the case of  holders of  shares
represented  by  certificates  upon  the surrender  to  the  corporation  of the
certificates representing  such stock.  The Court's  decree may  be enforced  as
other  decrees in the Court of Chancery  may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
    (j)  The costs of  the proceeding may be determined  by the Court and  taxed
upon  the  parties  as the  Court  deems  equitable in  the  circumstances. Upon
application of  a stockholder,  the Court  may order  all or  a portion  of  the
expenses   incurred  by  any  stockholder   in  connection  with  the  appraisal
proceeding, including, without  limitation, reasonable attorney's  fees and  the
fees  and expenses of experts,  to be charged pro rata  against the value of all
the shares entitled to an appraisal.
 
                                      B-3
<PAGE>
    (k) From and  after the effective  date of the  merger or consolidation,  no
stockholder  who has demanded his appraisal rights as provided in subsection (d)
of this section  shall be  entitled to  vote such stock  for any  purpose or  to
receive  payment  of  dividends  or other  distributions  on  the  stock (except
dividends or other  distributions payable to  stockholders of record  at a  date
which  is prior to the effective date of the merger or consolidation); provided,
however, that if no  petition for an  appraisal shall be  filed within the  time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an  appraisal and an acceptance of the merger or consolidation, either within 60
days after the  effective date  of the merger  or consolidation  as provided  in
subsection  (e) of this section  or thereafter with the  written approval of the
corporation, then the  right of such  stockholder to an  appraisal shall  cease.
Notwithstanding  the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court,  and
such approval may be conditioned upon such terms as the Court deems just.
 
    (l) The shares of the surviving or resulting corporation to which the shares
of  such objecting stockholders  would have been converted  had they assented to
the merger or  consolidation shall have  the status of  authorized and  unissued
shares  of the surviving or  resulting corporation. (Last amended  by Ch. 79, L.
'95, eff. 7-1-95.)

    THIRD: The purpose  of the Corporation  is to  engage in any  lawful act  or
activity  for which corporations may be  organized under the General Corporation
Law of the State of Delaware.
    
 
   
                                  IV.  STOCK.
    
 
   
    FOURTH:
    
 
   
    A.  This  Corporation is authorized  to issue  two classes of  shares to  be
designated,  respectively, Preferred Stock ("Preferred  Stock") and Common Stock
("Common Stock").  The  total  number  of  shares  of  capital  stock  that  the
Corporation  is authorized to issue is 57,238,000. The total number of shares of
Preferred Stock this Corporation shall have authority to issue is 21,288,000, of
which 15,788,000 shares shall be designated Series A Preferred Stock ("Series  A
Stock")  and  5,500,000  shares shall  be  designated Series  B  Preferred Stock
("Series B Stock"). The total number of shares of Common Stock this  Corporation
shall  have authority to issue is 35,950,000. Upon the amendment of this Article
to read as set  forth herein, each share  of Preferred Stock outstanding  before
such amendment held by a stockholder shall be converted into one share of Series
A  Stock. The Preferred Stock shall have a  par value of $.001 per share and the
Common Stock shall have  a par value  of $.001 per  share. 21,288,000 shares  of
Common  Stock shall  be reserved for  issuance upon conversion  of the Preferred
Stock. The  number of  authorized shares  of Common  Stock may  be increased  or
decreased  (but not only  below the number  of shares of  such Common Stock then
outstanding) by  the  affirmative  vote  of  a majority  of  all  stock  of  the
Corporation  entitled  to vote,  voting together  as a  single class.  Except as
specifically provided below, the Preferred Stock  and the Common Stock shall  in
all  respects be identical and shall  have the same powers, preferences, rights,
restrictions and other characteristics.
    
 
   
    B.  The powers, preferences, rights, restrictions, and other characteristics
relating to the Series A Stock and Series B Stock are as follows:
    
 
   
       1.  LIQUIDATION PREFERENCE.
    
 
   
           a.  In the event of any liquidation, dissolution or winding up of the
       Corporation, whether voluntary  or involuntary, the  holders of Series  A
       Stock  and Series B Stock, PARI PASSU  with each other, shall be entitled
       to receive, prior  and in preference  to any distribution  of any of  the
       assets  or surplus funds of the Corporation  to the holders of the Common
       Stock by reason of their ownership thereof, the amount of $0.40 per share
       of Series A Stock (the "Series A  Stock Issue Price") and $1.00 for  each
       share  of Series  B Stock  (the "Series  B Stock  Issue Price")  (each as
       adjusted for any stock dividends, combinations or splits with respect  to
       such  shares). If upon the occurrence of such event, the assets and funds
       thus distributed
    
 
                                      C-1
<PAGE>
   
       among the holders of the Preferred Stock shall be insufficient to  permit
       the  payment to such  holders of the  full aforesaid preferential amount,
       then the entire assets and funds of the Corporation legally available for
       distribution shall  be  distributed  ratably among  the  holders  of  the
       Preferred Stock in proportion to the preferential amount each such holder
       is otherwise entitled to receive.
    
 
   
           b.    After payment  to the  holders  of the  Preferred Stock  of the
       amounts set forth in  Section B.1.a. above,  the entire remaining  assets
       and  funds of the Corporation legally available for distribution, if any,
       shall be  distributed among  the  holders of  the  Common Stock  and  the
       Preferred  Stock in proportion to the shares of Common Stock then held by
       them and the shares of Common Stock which they have the right to  acquire
       upon conversion of the shares of Preferred Stock then held by them.
    
 
   
           c.   For purposes  of this Section  B.1., (i) any  acquisition of the
       Corporation by means of merger or other form of corporate  reorganization
       in  which  outstanding  shares  of  the  Corporation  are  exchanged  for
       securities or other consideration issued, or caused to be issued, by  the
       acquiring   corporation   or   its   subsidiary   (other   than   a  mere
       reincorporation transaction) or (ii) a  sale of all or substantially  all
       of the assets of the Corporation (collectively, events under this Section
       B.1(c)  shall hereafter be referred to as an "Acquisition"), shall not be
       treated as a liquidation, dissolution  or winding up of the  Corporation.
       In  each such  case, any  cash, securities  or other  property (valued as
       provided in Section B.1.d. below)  delivered pursuant to an  Acquisition,
       shall  be  distributed among  the  holders of  the  Common Stock  and the
       Preferred Stock in proportion to the shares of Common Stock then held  by
       them  and the shares of Common Stock which they have the right to acquire
       upon conversion of the shares of Preferred Stock then held by them.
    
 
   
           d.  Whenever the distribution provided for in this Section B.1. shall
       be payable in securities or property  other than cash, the value of  such
       distribution  shall be the fair market  value of such securities or other
       property as determined in good faith by the Board of Directors.
    
 
   
       2.  VOTING RIGHTS; DIRECTORS.
    
 
   
           a.  Each holder of shares of Preferred Stock shall be entitled to the
       number of votes equal to the number of shares of Common Stock into  which
       such  shares of Preferred Stock could  be converted and shall have voting
       rights and powers  equal to the  voting rights and  powers of the  Common
       Stock  (except as otherwise  expressly provided herein  or as required by
       law, voting together with the Common  Stock as a single class) and  shall
       be entitled to notice of any stockholders' meeting in accordance with the
       Bylaws  of  the  Corporation.  Fractional votes  shall  not,  however, be
       permitted and  any  fractional voting  rights  resulting from  the  above
       formula  (after  aggregating all  shares into  which shares  of Preferred
       Stock held by  each holder could  be converted) shall  be rounded to  the
       nearest whole number (with one-half being rounded upward). Each holder of
       Common  Stock shall be entitled to one  (1) vote for each share of Common
       Stock held.
    
 
   
           b.   Each holder  of shares  of Preferred  Stock and  each holder  of
       shares  of  the  Common  Stock  shall be  entitled  at  all  elections of
       directors to  as many  votes as  shall equal  the number  of votes  which
       (except  for this provision as to cumulative voting) he would be entitled
       to cast for the election of directors with respect to his shares of stock
       multiplied by the number of directors to be elected, and such holder  may
       cast all of such votes for a single director or may distribute them among
       the  number to be voted for, or for any two or more of them as he may see
       fit, and to one vote for each share upon all other matters. The right  to
       cumulative  voting in the election of directors set forth in this Section
       B.2.b.  shall  expire  upon  the  first  sale  of  Common  Stock  of  the
       Corporation  to  the public  pursuant to  a registration  statement filed
       with, and declared effective by, the Securities and Exchange Commission.

<PAGE>
   
       3.  CONVERSION.   The holders  of Preferred Stock  shall have  conversion
       rights as follows (the "Conversion Rights"):
    
 
   
           a.  RIGHT TO CONVERT. Each share of Series A Stock and Series B Stock
       shall  be convertible, at the  option of the holder  thereof, at any time
       after the  date  of  issuance  of  such  share,  at  the  office  of  the
       Corporation  or any  transfer agent for  such stock, into  such number of
       fully paid and nonassessable shares of  Common Stock as is determined  by
       dividing the Series A Stock Issue Price or Series B Stock Issue Price, as
       the  case  may  be by  the  Conversion  Price applicable  to  such share,
       determined as hereinafter provided, in effect on the date the certificate
       is surrendered for conversion. The price at which shares of Common  Stock
       shall  be deliverable upon conversion of shares  of the Series A Stock or
       Series B Stock (the "Conversion Price")  shall initially be the Series  A
       Stock  Issue Price  and Series  B Stock  Issue Price,  respectively. Such
       initial Conversion Price shall be adjusted as hereinafter provided.
    
 
   
           b.  AUTOMATIC CONVERSION.
    
 
   
               (i) Each share of Series A Stock shall automatically be converted
           into shares of Common Stock at then-effective Conversion Price,  upon
           the  earlier of (x) the date specified  by vote or written consent or
           agreement of holders of  at least two-thirds (2/3)  of the shares  of
           Series  A Stock then outstanding, or (y) immediately upon the closing
           of the sale of the Corporation's  Common Stock in a firm  commitment,

           relating  solely to a  transaction under Rule 145  under such Act (or
           any successor  thereto)  or  to  an  employee  benefit  plan  of  the
           Corporation,  at  a  public offering  price  (prior  to underwriters'
           discounts and expenses)  at a per  share offering price  equal to  or

           dividends, combinations or  splits with respect  to such shares)  and
           the  aggregate proceeds of which  to the Corporation (after deduction
           for underwriters' discounts  and expenses relating  to the  issuance,
           including,  without  limitation, fees  of the  Corporation's counsel)
           exceed $10,000,000.

           c.  MECHANICS OF CONVERSION.
    
 
   
               (i)  Before any holder of Series A  Stock or Series B Stock shall
           be entitled to convert the same into shares of Common Stock, he shall
           surrender the certificate or certificates therefor, duly endorsed, at
           the office  of the  Corporation or  of any  transfer agent  for  such
           stock,  and  shall give  written notice  to  the Corporation  at such
           office that he elects to convert the same and shall state therein the
           name or names in which he wishes the certificate or certificates  for
           shares  of Common Stock to be  issued. The Corporation shall, as soon
           as practicable thereafter, issue and  deliver at such office to  such
           holder  of  Series  A  Stock  or Series  B  Stock,  a  certificate or
           certificates for the number of shares of
    
 
                                      C-3
<PAGE>
   
           Common Stock  to  which  he  shall be  entitled  as  aforesaid.  Such
           conversion shall be deemed to have been made immediately prior to the
           close  of business on the date of surrender of the shares of Series A
           Stock or Series B  Stock to be converted,  and the person or  persons
           entitled  to receive  the shares of  Common Stock  issuable upon such
           conversion shall be treated for all purposes as the record holder  or
           holders of such shares of Common Stock on such date.
    
 
   
               (ii)  If  the conversion  is in  connection with  an underwritten
           offering of securities pursuant to the Securities Act, the conversion
           may, at the option of any  holder tendering shares of Series A  Stock
           or  Series B  Stock for conversion,  be conditioned  upon the closing
           with the  underwriters of  the sale  of securities  pursuant to  such
           offering, in which event the person(s) entitled to receive the Common
           Stock  upon conversion of the Series A  Stock or Series B Stock shall
           not be deemed to have converted such Series A Stock or Series B Stock
           until immediately prior to the closing of such sale of securities.
    
 
   
           d.  ADJUSTMENTS TO CONVERSION PRICE FOR CERTAIN DILUTING ISSUES.
    
 
   
               (i) SPECIAL DEFINITIONS.   For purposes  of this Section  B.3.d.,
           the following definitions apply:
    
 
   
                   (1)  "Options"  shall mean  rights,  options, or  warrants to
               subscribe for, purchase or otherwise acquire either Common  Stock
               or Convertible Securities (defined below).
    
 
   
                   (2)  "Original Issue  Date" shall  mean the  date on  which a
               share of Series A Stock or Series B Stock was first issued.
    
 
   
                   (3) "Convertible  Securities"  shall mean  any  evidences  of
               indebtedness,  shares  (other  than  Common  Stock  and Preferred
               Stock) or other securities  convertible into or exchangeable  for
               Common Stock.
    
 
   
                   (4) "Additional Shares of Common Stock" shall mean all shares
               of  Common Stock  issued (or,  pursuant to  Section B.3.d. (iii),
               deemed to be issued) by the Corporation after the Original  Issue
               Date, other than shares of Common Stock issued or issuable:
    
 
   
                       (A) upon conversion of shares of Preferred Stock;
    
 
   
                       (B) to   officers,   directors   or   employees   of,  or
                           consultants to,  the  Corporation pursuant  to  stock
                   option  or  stock  purchase  plans  or  agreements  on  terms
                   approved  by  the  Board  of  Directors,  but  not  exceeding
                   13,290,000  shares of Common Stock (net of any repurchases of
                   such shares  or  cancellations or  expirations  of  options),
                   subject to adjustment for all subdivisions and combinations;
    
 
   
                       (C) to  C-Cube Microsystems, but  not exceeding 1,372,000
                           shares of Common Stock;
    
 
   
                       (D) as a dividend or distribution on Preferred Stock; or
    
 
   
                       (E) for which adjustment of the Conversion Price is  made
                           pursuant to Section B.3.e.
    
 
   
               (ii)  NO ADJUSTMENT OF CONVERSION  PRICE. Any provision herein to
           the contrary notwithstanding, no  adjustment in the Conversion  Price
           for  Series A Stock or Series B Stock shall be made in respect of the
           issuance  of   Additional  Shares   of   Common  Stock   unless   the
           consideration  per share  (determined pursuant to  Section B.3.d. (v)
           hereof) for an
    
 
                                      C-4
<PAGE>
   
           Additional Share of Common Stock issued or deemed to be issued by the
           Corporation is less than the Conversion Price for such Series A Stock
           or Series B Stock in effect on the date of, and immediately prior to,
           such issue.
    
 
   
              (iii) DEEMED ISSUE OF  ADDITIONAL SHARES OF  COMMON STOCK. In  the
           event  the Corporation  at any  time or  from time  to time  after an
           Original Issue Date shall issue any Options or Convertible Securities
           or shall fix a  record date for the  determination of holders of  any
           class  of securities  then entitled  to receive  any such  Options or
           Convertible Securities, then  the maximum  number of  shares (as  set
           forth  in  the  instrument  relating thereto  without  regard  to any
           provisions contained therein designed to protect against dilution) of
           Common Stock issuable upon  the exercise of such  Options or, in  the
           case  of Convertible Securities and  Options therefor, the conversion
           or exchange  of such  Convertible  Securities and  Options  therefor,
           shall  be deemed to be Additional Shares of Common Stock issued as of
           the time of such issue or, in case such a record date shall have been
           fixed, as of the close of business on such record date, provided that
           in any  such case  in which  Additional Shares  of Common  Stock  are
           deemed to be issued:
    
 
   
                   (1)  no further adjustments in  the Conversion Price shall be
               made upon  the  subsequent  issue of  Convertible  Securities  or
               shares  of  Common Stock  upon the  exercise  of such  Options or
               conversion or exchange of such Convertible Securities;
    
 
   
                   (2) If such Options or Convertible Securities by their  terms
               provide,  with the passage of time or otherwise, for any increase
               or decrease in the consideration  payable to the Corporation,  or
               decrease  or increase  in the  number of  shares of  Common Stock
               issuable, upon the exercise, conversion or exchange thereof,  the
               Conversion  Price computed  upon the  original issue  thereof (or
               upon the occurrence of a  record date with respect thereto),  and
               any  subsequent adjustments  based thereon, shall,  upon any such
               increase or decrease becoming effective, be recomputed to reflect
               such increase or decrease insofar  as it affects such Options  or
               the  rights  of  conversion or  exchange  under  such Convertible
               Securities (provided,  however, that  no such  adjustment of  the
               Conversion Price shall affect Common Stock previously issued upon
               conversion of the Series A Stock or Series B Stock);
    
 
   
                   (3)  upon the expiration of any such Options or any rights of
               conversion or exchange  under such  Convertible Securities  which
               shall not have been exercised, the Conversion Price computed upon
               the  original issue thereof  (or upon the  occurrence of a record
               date with respect thereto), and any subsequent adjustments  based
               thereon, shall, upon such expiration, be recomputed as if:
    
 
   
                       (A) in  the case of Convertible Securities or Options for
                           Common Stock, the  only Additional  Shares of  Common
                   Stock  issued  were  the  shares  of  Common  Stock,  if any,
                   actually issued  upon the  exercise of  such Options  or  the
                   conversion or exchange of such Convertible Securities and the
                   consideration   received   therefor  was   the  consideration
                   actually received by  the Corporation  for the  issue of  all
                   such   Options,   whether   or   not   exercised,   plus  the
                   consideration actually received by the Corporation upon  such
                   exercise, or for the issue of all such Convertible Securities
                   which   were  actually  converted   or  exchanged,  plus  the
                   additional consideration, if  any, actually  received by  the
                   Corporation upon such conversion or exchange; and
    
 
   
                       (B) in  the case  of Options  for Convertible Securities,
                           only the  Convertible  Securities, if  any,  actually
                   issued  upon the exercise thereof were  issued at the time of
                   issue of such Options, and the consideration received by  the
                   Corporation  for the Additional Shares of Common Stock deemed
                   to have  been  then  issued was  the  consideration  actually
                   received  by  the  Corporation  for  the  issue  of  all such
                   Options, whether  or not  exercised, plus  the  consideration
                   deemed to have
    
 
                                      C-5
<PAGE>
   
                   been  received  by  the Corporation  (determined  pursuant to
                   Section B.3.d.) upon the issue of the Convertible  Securities
                   with respect to which such Options were actually exercised;
    
 
   
                   (4) no readjustment pursuant to clause (2) or (3) above shall
               have  the effect of increasing the  Conversion Price to an amount
               which exceeds  the  lower of  (a)  the Conversion  Price  on  the
               original  adjustment date, or (b) the Conversion Price that would
               have resulted from  any issuance of  Additional Shares of  Common
               Stock  between the original adjustment date and such readjustment
               date.
    
 
   
              (iv) ADJUSTMENT OF  CONVERSION PRICE UPON  ISSUANCE OF  ADDITIONAL
           SHARES  OF COMMON  STOCK. In the  event this Corporation  at any time
           after the Original Issue Date shall issue Additional Shares of Common
           Stock (including  Additional  Shares of  Common  Stock deemed  to  be
           issued  pursuant to Section B.3.d.(iii)) without consideration or for
           a consideration per share less than the Conversion Price with respect
           to Series A  Stock or  Series B  Stock in effect  on the  date of  an
           immediately  prior  to  such  issue,  then  and  in  such  event, the
           Conversion Price for such Series A  Stock or Series B Stock shall  be
           reduced,  concurrently with such issue, to a price (calculated to the
           nearest cent) determined  by multiplying such  Conversion Price by  a
           fraction,  the numerator  of which shall  be the number  of shares of
           Common Stock outstanding  immediately prior  to such  issue plus  the
           number  of shares of  Common Stock which  the aggregate consideration
           received by the Corporation for the total number of Additional Shares
           of Common Stock so issued would purchase at such Conversion Price  in
           effect  immediately prior  to such  issuance, and  the denominator of
           which shall  be the  number  of shares  of Common  Stock  outstanding
           immediately  prior to such  issue plus the  number of such Additional
           Shares of  Common Stock  so  issued. For  the  purpose of  the  above
           calculation,  the  number  of  shares  of  Common  Stock  outstanding
           immediately prior  to  such issue  shall  be calculated  on  a  fully
           diluted   basis,  as  if  all  shares  of  Preferred  Stock  and  all
           Convertible Securities had been fully converted into shares of Common
           Stock  immediately  prior  to  such  issuance  and  any   outstanding
           warrants, options or other rights for the purchase of shares of stock
           or  convertible securities had been fully exercised immediately prior
           to such issuance (and the  resulting securities fully converted  into
           shares  of Common Stock, if so convertible)  as of such date, but not
           including in such calculation any  additional shares of Common  Stock
           issuable  with  respect  to shares  of  Preferred  Stock, Convertible
           Securities, or outstanding options, warrants or other rights for  the
           purchase  of shares of  stock or convertible  securities, solely as a
           result of  the adjustment  of the  respective Conversion  Prices  (or
           other  conversion rations) resulting from  the issuance of Additional
           Shares of Common Stock causing such adjustment.
    
 
   
               (v) DETERMINATION OF CONSIDERATION. For purposes of this  Section
           B.3.d.,  the consideration received by  the Corporation for the issue
           of any  Additional  Shares  of  Common Stock  shall  be  computed  as
           follows:
    
 
   
                   (1) CASH AND PROPERTY. Such consideration shall:
    
 
   
                       (A) insofar  as it consists  of cash, be  computed at the
                           aggregate amount of cash received by the Corporation;
    
 
   
                       (B) insofar as it consists  of property other than  cash,
                           be  computed at the fair value thereof at the time of
                   such issue, as determined in good faith by the Board; and
    
 
                                      C-6
<PAGE>
   
                       (C) in the event  Additional Shares of  Common Stock  are
                           issued  together with  other shares  or securities or
                   other assets  of  the  Corporation  for  consideration  which
                   covers  both,  be  the proportion  of  such  consideration so
                   received, computed as provided in clauses (A) and (B)  above,
                   as determined in good faith by the Board.
    
 
   
                   (2) OPTIONS AND CONVERTIBLE SECURITIES. The consideration per
               share received by the Corporation for Additional Shares of Common
               Stock  deemed  to have  been  issued pursuant  to  Section B.3.d.
               (iii), relating to  Options and Convertible  Securities shall  be
               determined by dividing:
    
 
   
                       (A) the  total amount, if any,  received or receivable by
                           the Corporation  as consideration  for the  issue  of
                   such  Options  or  Convertible Securities,  plus  the minimum
                   aggregate amount of additional consideration (as set forth in
                   the instruments  relating  thereto,  without  regard  to  any
                   provision  contained  therein  designed  to  protect  against
                   dilution) payable  to the  Corporation upon  the exercise  of
                   such   Options  or   the  conversion  or   exchange  of  such
                   Convertible  Securities,  or  in  the  case  of  Options  for
                   Convertible  Securities,  the  exercise of  such  Options for
                   Convertible Securities and the conversion or exchange of such
                   Convertible Securities by
    
 
   
                       (B) the maximum number of shares of Common Stock (as  set
                           forth  in the  instruments relating  thereto, without
                   regard to any provision contained therein designed to protect
                   against the  dilution) issuable  upon  the exercise  of  such
                   Options   or  conversion  or  exchange  of  such  Convertible
                   Securities.
    
 
   
           e.   ADJUSTMENTS TO  CONVERSION PRICES  FOR STOCK  DIVIDENDS AND  FOR
       COMBINATIONS  OR SUBDIVISIONS  OF COMMON  STOCK. In  the event  that this
       Corporation at any  time or from  time to time  after the Original  Issue
       Date  shall declare  or pay, without  consideration, any  dividend on the
       Common Stock payable in  Common Stock or in  any right to acquire  Common
       Stock  for  no  consideration,  or  shall  effect  a  subdivision  of the
       outstanding shares of  Common Stock into  a greater number  of shares  of
       Common  Stock  (by stock  split,  reclassification or  otherwise  than by
       payment of a dividend in Common Stock  or in any right to acquire  Common
       Stock),  or in the event the outstanding  shares of Common Stock shall be
       combined or consolidated, by reclassification or otherwise, into a lesser
       number of shares of Common Stock, then the Conversion Price for Series  A
       Stock  or Series  B Stock shall,  concurrently with  the effectiveness of
       such event, be proportionately decreased or increased, as appropriate. In
       the  event  that   this  Corporation  shall   declare  or  pay,   without
       consideration,  any dividend on the Common  Stock payable in any right to
       acquire Common Stock for no consideration, then the Corporation shall  be
       deemed  to have made a  dividend payable in Common  Stock in an amount of
       shares equal to the  maximum number of shares  issuable upon exercise  of
       such rights to acquire Common Stock.
    
 
   
           f.    ADJUSTMENTS  FOR RECLASSIFICATION  AND  REORGANIZATION.  If the
       Common Stock issuable upon conversion of  the Series A Stock or Series  B
       Stock  shall be changed into the same  or a different number of shares of
       any other class or classes  of stock, whether by capital  reorganization,
       reclassification or otherwise (other than a subdivision or combination of
       shares  provided for in Section B.3.e.  above), the Conversion Price then
       in  effect   shall,  concurrently   with   the  effectiveness   of   such
       reorganization  or reclassification, be  proportionately adjusted so that
       the Series A Stock or Series B  Stock shall be convertible into, in  lieu
       of the number of shares of Common Stock which the holders would otherwise
       have  been entitled to receive, a number of shares of such other class or
       classes of stock equivalent to the number of shares of Common Stock  that
       would  have been subject to receipt by the holders upon conversion of the
       Series A Stock or Series B Stock immediately before that change.

<PAGE>
   
           g.  NO  IMPAIRMENT. The  Corporation will  not, by  amendment of  its
       Certificate  of Incorporation or through  any reorganization, transfer of
       assets, consolidation, merger, dissolution,  issue or sale of  securities
       or  any other voluntary action, avoid or  seek to avoid the observance or
       performance of any of the terms to be observed or performed hereunder  by
       the  Corporation,  but will  at all  times  in good  faith assist  in the
       carrying out of all the provisions of this Section B.3. and in the taking
       of all such action as may be necessary or appropriate in order to protect
       the Conversion Rights of the  holders of the Series  A Stock or Series  B
       Stock against impairment.
    
 
   
           h.    CERTIFICATES AS  TO ADJUSTMENTS.  Upon  the occurrence  of each
       adjustment or  readjustment  of any  Conversion  Price pursuant  to  this
       Section B.3., the Corporation at its expense
       shall promptly compute such adjustment or readjustment in accordance with
       the  terms hereof  and prepare  and furnish  to each  holder of Preferred
       Stock a  certificate executed  by the  Corporation's President  or  Chief
       Financial  Officer  setting  forth such  adjustment  or  readjustment and
       showing in detail the facts upon which such adjustment or readjustment is
       based. The Corporation shall, upon the written request at any time of any
       holder of  Preferred Stock,  furnish or  cause to  be furnished  to  such
       holder  a  like  certificate  setting  forth  (i)  such  adjustments  and
       readjustments, (ii) the  Conversion Price  for such  series of  Preferred
       Stock  at the time  in effect, and  (iii) the number  of shares of Common
       Stock and the amount, if any, of  other property which at the time  would
       be received upon the conversion of the Preferred Stock.
    
 
   
           i.   NOTICES OF RECORD DATE. In  the event that the Corporation shall
       propose at any time: (i) to declare any dividend or distribution upon its
       Common Stock,  whether  in cash,  property,  stock or  other  securities,
       whether or not a regular cash dividend and whether or not out of earnings
       or earned surplus; (ii) to offer for subscription pro rata to the holders
       of any class or series of its stock any additional shares of stock of any
       class  or series or other rights; (iii) to effect any reclassification or
       recapitalization of its  Common Stock outstanding  involving a change  in
       the  Common Stock; or (iv) to merge or consolidate with or into any other
       corporation, or sell,  lease or convey  all or substantially  all of  its
       assets,  or to liquidate,  dissolve or wind up;  then, in connection with
       each such event, the Corporation shall  send to the holders of  Preferred
       Stock:
    
 
   
               (1)  at least twenty (20) days'  prior written notice of the date
           on which a record shall be  taken for such dividend, distribution  or
           subscription  rights (and specifying the date on which the holders of
           Common Stock shall be entitled thereto) or for determining rights  to
           vote, if any, in respect of the matters referred to in (iii) and (iv)
           above; and
    
 
   
               (2)  in the  case of  the matters referred  to in  (iii) and (iv)
           above, at least twenty  (20) days' prior written  notice of the  date
           when  the same shall take place (and specifying the date on which the
           holders of Common Stock  shall be entitled  to exchange their  Common
           Stock   for  securities  or  other   property  deliverable  upon  the
           occurrence of such event).
    
 
   
           j.  ISSUE  TAXES. The  Corporation shall pay  any and  all issue  and
       other  taxes that may be  payable in respect of  any issue or delivery of
       shares of Common Stock on conversion of Preferred Stock pursuant  hereto;
       provided, however, that the Corporation shall not be obligated to pay any
       transfer  taxes resulting  from any transfer  requested by  any holder in
       connection with any such conversion.
    
 
   
           k.  RESERVATION  OF STOCK ISSUABLE  UPON CONVERSION. The  Corporation
       shall  at all times reserve and keep  available out of its authorized but
       unissued shares of Common Stock, solely for the purpose of effecting  the
       conversion  of  the shares  of the  Preferred Stock,  such number  of its
       shares of Common Stock as shall from time to time be sufficient to effect
       the conversion of all outstanding shares  of the Preferred Stock; and  if
       at  any time the number of authorized but unissued shares of Common Stock
       shall not be sufficient to effect the conversion of all then  outstanding
       shares  of the Preferred Stock, the  Corporation will take such corporate
    
 
                                      C-8
<PAGE>
   
       action as may, in  the opinion of its  counsel, be necessary to  increase
       its  authorized but  unissued shares  of Common  Stock to  such number of
       shares as  shall  be  sufficient for  such  purpose,  including,  without
       limitation,  engaging in best efforts to obtain the requisite stockholder
       approval of any necessary amendment to this Certificate.
    
 
   
           l.  FRACTIONAL SHARES. No fractional  share shall be issued upon  the
       conversion  of  any share  or shares  of Preferred  Stock. All  shares of
       Common Stock (including  fractions thereof) issuable  upon conversion  of
       more  than one (1) share of Preferred  Stock by a holder thereof shall be
       aggregated for  purposes  of  determining whether  the  conversion  would
       result   in  the  issuance  of  any   fractional  share.  If,  after  the
       aforementioned aggregation, the conversion  would result in the  issuance
       of  a fraction of a share of Common Stock, the Corporation shall, in lieu
       of issuing any  fractional share,  pay the holder  otherwise entitled  to
       such  fraction  a sum  in cash  equal to  the fair  market value  of such
       fraction on the date  of conversion (as determined  in good faith by  the
       Board of Directors).
    
 
   
           m.  NOTICES. Any  notice required by  the provisions  of this Section
       B.3. to be given  to the holders  of shares of  Preferred Stock shall  be
       deemed given if deposited in the United States mail, postage prepaid, and
       addressed  to each holder of record at his address appearing on the books
       of the Corporation.
    
 
   
       4.  DIVIDENDS.  No dividends shall  be paid on any share of Common  Stock
       unless  a  dividend is  paid with  respect to  all outstanding  shares of
    Preferred Stock in an amount for each such share of Preferred Stock equal to
    or greater than  the aggregate amount  of such dividends  for all shares  of
    Common  Stock into which  each such share  of Preferred Stock  could then be
    converted.
    
 
   
       5.  RESTRICTIONS AND LIMITATIONS.
    
 
   
           a.  So long as any shares of Preferred Stock remain outstanding,  the
       Corporation shall not, without the vote or written consent by the holders
       of  at least  66 2/3%  of the  then outstanding  shares of  the Preferred
       Stock:
    
 
   
                i) amend the Certificate of Incorporation of the Corporation;
    
 
   
                ii) issue any shares of Common Stock if the number of shares  of
           Common  Stock  remaining authorized  and  unissued is  less  than the
           number of  shares  of Common  Stock  into  which all  the  shares  of
           authorized Preferred Stock could be converted immediately before such
           issuance; or
    
 
   
               iii)  effect  any  sale, lease,  assignment,  transfer,  or other
           conveyance  of  all  or  substantially  all  of  the  assets  of  the
           Corporation  or  any of  its  subsidiaries, or  any  consolidation or
           merger involving the Corporation or  any of its subsidiaries, or  any
           reclassification   or   other   change   of   any   stock,   or   any
           recapitalization of the Corporation.
    
 
   
           b.  So long as any shares of Preferred Stock remain outstanding,  the
       Corporation shall not, without the vote or written consent by the holders
       of  at  least 66  2/3% of  the then  outstanding shares  of stock  of the
       Corporation, voting together  as a  single class, elect  to dissolve  the
       Corporation.
    
 
   
       6.   NO REISSUANCE OF  PREFERRED STOCK.  No  share or shares of Preferred
       Stock acquired  by the  Corporation by  reason of  redemption,  purchase,
    conversion  or otherwise  shall be  reissued, and  all such  shares shall be
    cancelled, retired  and eliminated  from the  shares which  the  Corporation
    shall be authorized to issue.

receipt  of any payment  for any of  the Corporation's capital  stock, to adopt,
amend, repeal  or otherwise  alter the  Bylaws of  the Corporation  without  any
action  on the part  of the stockholders;  provided, however, that  the grant of
such power to the Board  of Directors shall not  divest the stockholders of  nor
limit  their power, subject to the provisions of Section B.6. of Article FOURTH,
to adopt, amend, repeal or otherwise alter the Bylaws.
    
 
   
                          VI.  ELECTION OF DIRECTORS.

    SEVENTH:  The Corporation  reserves the right  to adopt,  repeal, rescind or
amend  in  any  respect  any   provisions  contained  in  this  Certificate   of
Incorporation in the manner now or hereafter prescribed by applicable law and in

herein are granted subject to this reservation.
    
 
   
                           VIII.  DIRECTOR LIABILITY.

the Delaware General Corporation Law as it now exists or as it may hereafter  be
amended,  not  be liable  to the  Corporation or  its stockholders  for monetary

eliminate  or reduce the effect of this Article EIGHTH, in respect of any matter
occurring, or any  cause of action,  suit or  claim that, but  for this  Article
EIGHTH, would accrue or arise, prior to such amendment, repeal or adoption of an

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section  145 of the  Delaware General Corporation Law  authorizes a court to
award, or  a  corporation's Board  of  Directors to  grant,  indemnification  to
directors   and   officers  in   terms   sufficiently  broad   to   permit  such
indemnification  under   certain   circumstances  for   liabilities   (including
reimbursement  for expenses incurred) arising  under the Securities Act. Article
VIII  of   the   Registrant's  Bylaws   (Exhibit   3.2  hereto)   provides   for
indemnification  of its directors,  officers, employees and  other agents to the
maximum extent permitted by  the Delaware Law. In  addition, the registrant  has
entered  into Indemnification Agreements (Exhibit 10.1 hereto) with its officers
and directors.
 
    The Reorganization Agreement (Exhibit 2.1  hereto) provides that each  party
agrees  to indemnify and  hold harmless the other  party (including such party's
directors, officers, employees  and agents)  against, and with  respect to,  any
liability,  damages, losses, expenses or costs arising  from or by virtue of any
material misstatement  by such  party or  omission to  state any  fact which  is
required  to be disclosed  by such party  for purposes of  the inclusion of such
information in  any regulatory  filing made  on behalf  of the  parties for  the
purpose  of effecting the terms of  the Reorganization Agreement, including, but
not limited to, this Registration Statement and any amendments hereto.

    Form S-1 filed March 4, 1994, as amended (File No. 33-76082).

ITEM 22. UNDERTAKINGS
 
    (1) The undersigned registrant hereby  undertakes as follows: that prior  to
any  public reoffering of  the securities registered hereunder  through use of a
prospectus which is  a part  of this Registration  Statement, by  any person  or
party  who is deemed to be an underwriter within the meaning of Rule 145(c), the
undersigned registrant undertakes that  such reoffering prospectus will  contain
the  information called for by the  applicable registration form with respect to
reofferings by  persons who  may  be deemed  underwriters,  in addition  to  the
information called for by the other Items of the applicable form.
 
    (2)  The  registrant  undertakes that  every  prospectus (i)  that  is filed
pursuant to paragraph (1) immediately preceding,  or (ii) that purports to  meet
the  requirements of Section 10(a)(3) of the  Act and is used in connection with
an offering of securities  subject to Rule 415,  will be filed as  a part of  an
amendment  to  the  Registration  Statement  and will  not  be  used  until such
amendment is  effective, and  that, for  purposes of  determining any  liability
under  the Securities Act  of 1933, each such  post-effective amendment shall be
deemed to be  a new Registration  Statement relating to  the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
    (3) Insofar  as  the  indemnification  for  liabilities  arising  under  the
Securities  Act of 1933 may be  permitted to directors, officers and controlling
persons of the registrant  pursuant to the  foregoing provisions, or  otherwise,
the  registrant  has been  advised that  in  the opinion  of the  Securities and
Exchange Commission such indemnification is  against public policy as  expressed
in  the Act  and is,  therefore, unenforceable.  In the  event that  a claim for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
registrant  of expenses incurred  or paid by a  director, officer or controlling
person of  the registrant  in the  successful  defense of  any action,  suit  or
proceeding)  is  asserted by  such director,  officer  or controlling  person in
connection with the securities being registered, the registrant will, unless  in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to  a  court  of  appropriate  jurisdiction  the  question  whether such
indemnification by it is against public policy as expressed in the Act and  will
be governed by the final adjudication of such issue.

    (4)  The undersigned registrant hereby undertakes  to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent  or
given,  the latest  annual report  to security  holders that  is incorporated by
reference  in  the  prospectus  and  furnished  pursuant  to  and  meeting   the
requirements  of Rule 14a-3 or  Rule 14c-3 under the  Securities Exchange Act of
1934; and,  where interim  financial  information required  to be  presented  by
Article  3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to  each person to whom the  prospectus is sent or  given,
the  latest quarterly report  that is specifically  incorporated by reference in
the prospectus to provide such interim financial information.
 
    (5) The undersigned registrant hereby undertakes to respond to requests  for
information  that is incorporated  by reference into  the Prospectus pursuant to
Items 4, 10(b), 11  or 13 of this  Form, within one business  day of receipt  of
such  request, and  to send  the incorporated documents  by first  class mail or
other equally prompt  means. This  includes information  contained in  documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.
 
    (6)  The undersigned  registrant hereby undertakes  to supply by  means of a
post-effective amendment  all  information  concerning a  transaction,  and  the
company  being  acquired  involved therein,  that  was  not the  subject  of and
included in the Registration Statement when it became effective.
 
   
    (7) The  undersigned  registrant hereby  undertakes  that, for  purposes  of
determining  any liability under the Securities Act  of 1933, each filing of the
registrant's annual report  pursuant to section  13(a) or section  15(d) of  the
Securities  Exchange  Act of  1934  (and, where  applicable,  each filing  of an
employee  benefit  plan's  annual  report  pursuant  to  section  15(d)  of  the
Securities  Exchange  Act of  1934)  that is  incorporated  by reference  in the
registration statement  shall  be deemed  to  be a  new  registration  statement
relating  to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.
    
 
   
    (8) The undersigned registrant  hereby undertakes: (i)  To file, during  any
period  in which offers or  sales are being made,  a post-effective amendment to
this registration statement: (a) To  include any prospectus required by  section
10(a)(3)  of the Securities  Act of 1933;  (b) To reflect  in the prospectus any
facts or events arising after the  effective date of the registration  statement
(or  the most recent post-effective amendment thereof) which, individually or in
the aggregate, represent a  fundamental change in the  information set forth  in
the  registration  statement.  Notwithstanding the  foregoing,  any  increase or
decrease in  volume of  securities offered  (if the  total value  of  securities
offered  would not exceed that which was  registered) and any deviation from the
low or high end of the estimated maximum offering range may be reflected in  the
form  of prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price  represent no more than a 20%  change
in  the  maximum  aggregate offering  price  set  forth in  the  "Calculation of
Registration Fee"  table in  the effective  registration statement;  and (c)  To
include  any material information  with respect to the  plan of distribution not
previously disclosed in  the registration  statement or any  material change  to
such  information  in the  registration statement,  (ii)  That, for  purposes of
determining  any  liability  under  the  Securities  Act  of  1933,  each   such
post-effective  amendment shall  be deemed  to be  a new  registration statement
relating to the securities offered therein, and the offering of such  securities
at that time shall be deemed to be the initial BONA FIDE offering thereof, (iii)
To  remove from registration by  means of a post-effective  amendment any of the
securities being  registered  which remain  unsold  at the  termination  of  the
offering.

                                                                EXHIBIT 10.2


                               AFFILIATE AGREEMENT

     This Affiliate Agreement (this "AGREEMENT") is made and entered into as of
May 28, 1996, between C-Cube Microsystems Inc., a Delaware corporation ("C-
CUBE"), DiviCom Inc., a Delaware corporation ("DIVICOM"), Sagem S.A., Sagem
International S.A. and Tregor Electronique S.A., each a company organized under
the laws of France, and Iena International S.A., a company organized under the
laws of Luxembourg (collectively, "STOCKHOLDER").

                                    RECITALS

     A.   Concurrently with the execution of this Agreement, C-Cube and DiviCom
have entered into an Agreement and Plan of Reorganization (the "REORGANIZATION
AGREEMENT") which provides, among other things, for the merger (the "MERGER") of
DiviCom with and into C-Cube Acquisition Corp., a Delaware corporation and a
wholly-owned subsidiary of C-Cube ("MERGER SUB").  Pursuant to the Merger, all
outstanding capital stock of DiviCom will be canceled and extinguished and be
converted automatically into the right to receive shares of C-Cube Common Stock
pursuant to the Reorganization Agreement.

     B.   The Stockholder is the beneficial owner (as defined in Rule l3d-3
under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) of
such number of shares of the outstanding capital stock of DiviCom as is
indicated on Exhibit A to Agreement (the "SHARES").

     NOW THEREFORE, the parties agree as follows:

     1.   TAX TREATMENT:  RULE 145.  Stockholder understands and agrees that it
is intended that the Merger will be treated as a "reorganization" for federal
income tax purposes.  Stockholder further understands and agrees that
Stockholder may be deemed to be an "affiliate" of DiviCom within the meaning of
Rule 145 ("RULE 145") promulgated by the Securities and Exchange Commission (the
"SEC") under the Securities Act of 1933, as amended (the "SECURITIES ACT"),
although nothing contained herein should be construed as an admission of such
fact.

     2.   RELIANCE UPON REPRESENTATIONS WARRANTIES AND COVENANTS.  Stockholder
has been informed that the treatment of the Merger as a reorganization for
federal income tax purposes requires that former stockholders of DiviCom
maintain a meaningful continuing equity ownership interest in C-Cube after the
Merger.  Stockholder understands that the representations, warranties and
covenants of Stockholder set forth herein will be relied upon by C-Cube, DiviCom
and their respective counsel.

     3.   REPRESENTATIONS WARRANTIES AND COVENANTS OF STOCKHOLDER.  Stockholder
represents, warrants and covenants as follows:

          (a)  Stockholder has full power and authority to execute this
Agreement, to make the representations, warranties and covenants herein
contained and to perform Stockholder's obligations hereunder.

          (b)  Set forth below the signatures below is the number of Shares
owned by Stockholder, including all Shares as to which Stockholder has sole or
shared voting or investment


<PAGE>


power and all rights, options and warrants to acquire DiviCom Capital Stock 
owned or held by Stockholder.

          (c)  The shares of C-Cube Common Stock issued to Stockholder as
consideration in the Merger, and any C-Cube securities issued in exchange
therefor, are hereinafter referred to as "Restricted Securities".  The
Stockholder agrees, in addition to the limitations set forth in Section 3(d),
that as to a portion of the Restricted Securities representing two-thirds of all
Restricted Securities acquired by Stockholder less the amount contained in the
Escrow Fund pursuant to the Reorganization Agreement in respect of Stockholder,
Stockholder will not, for a period of 270 days from the date of this Agreement,
sell, transfer, exchange, pledge (except in connection with a bona fide loan
transaction), make charitable contributions in respect of; or otherwise dispose
of such portion of the Restricted Securities (or any option, right or other
interest with respect thereto).

          (d)  Notwithstanding the foregoing, Stockholder will not sell,
transfer, exchange, pledge (except in connection with a bona fide loan
transaction) or make charitable contributions in respect of; or otherwise
dispose of any Restricted Securities (or any interest with respect thereto),
unless: (i) such transaction is permitted pursuant to Rule 145(c) and 145(d)
under the Securities Act; or (ii) counsel representing Stockholder, which
counsel is reasonably satisfactory to C-Cube, shall have advised C-Cube in a
written opinion letter reasonably satisfactory to C-Cube and C-Cube's legal
counsel, and upon which C-Cube and its legal counsel may rely, that no
registration under the Securities Act would be required in connection with such
transaction; or (iii) a registration statement under the Securities Act covering
the Restricted Securities (or interests with respect thereto) proposed to be
disposed of, describing the manner and terms of the proposed disposition, and
containing a current prospectus, shall have been filed with the SEC and made
effective under the Securities Act; or (iv) an authorized representative of the
SEC shall have rendered written advice to Stockholder (sought by Stockholder or
counsel to Stockholder, with a copy thereof and all other related communications
delivered to C-Cube) to the effect that the SEC would take no action, or that
the staff of the SEC would not recommend that the SEC take any action, with
respect to the proposed disposition if consummated.

          (e)  Stockholder has no present plan or intent to sell, transfer,
exchange, pledge (other than in a preexisting bona fide margin account) or
otherwise dispose of; including a distribution by a corporation to its
stockholders (but excluding transactions among family members for tax or estate
planning purposes or among corporate affiliates, and transfers occurring by
operation of law or pursuant to court order) any of the shares of C-Cube Common
Stock that Stockholder may acquire in connection with the Merger.  If any of
Stockholder's representations in this subsection (e) cease to be true at any
time prior to the Effective Time of the Merger, Stockholder will deliver to each
of DiviCom and C-Cube, prior to the Effective Time of the Merger, a written
statement to that effect, signed by Stockholder.

     4.   RULES 144 AND 145.  From and after the Effective Time of the Merger
and for so long as is necessary in order to permit Stockholder to sell the C-
Cube Common Stock held by Stockholder pursuant to Rule 145 and, to the extent
applicable, Rule 144 under the Securities Act, C-Cube will use its best efforts
to file on a timely basis all reports required to be filed by it pursuant to
Section 13 of the Securities Exchange Act of 1934, as amended, referred to in


                                       2

<PAGE>

paragraph (c)(1) of Rule 144 under the Securities Act.  In addition, C-Cube
acknowledges that the covenants herein are given by Stockholder in reliance upon
the Registration Rights Agreement being executed concurrently with the Merger
and are contingent upon C-Cube's compliance with such Registration Rights
Agreement.

     5.   LIMITED RESALES.  Stockholder understands that, in addition to the
restrictions imposed under Section 4, the provisions of Rule 145 limit
Stockholder's public resales of Restricted Securities, in the manner set forth
in subsections (a), (b) and (c) below:

          (a)  Unless and until the restriction "Cut-off" provisions of Rule
l45(d)(2) or Rule l45(d)(3) set forth below become available, public resales of
Restricted Securities may only be made by Stockholder in compliance with the
requirements of Rule 145(d)(1).  Rule 145(d)(1) permits such resales only: (i)
while C-Cube meets the public information requirements of Rule 144(c); (ii) in
broker's transactions or in transactions with a market maker; and (iii) where
the aggregate number of Restricted Securities sold at any time together with all
sales of restricted C-Cube Common Stock sold for Stockholder's account during
the preceding three (3) month period does not exceed the greater of (A) one
percent (1%) of the C-Cube Common Stock outstanding or (B) the average weekly
volume of trading in C-Cube Common Stock on all national securities exchanges,
or reported through the automated quotation system of a registered securities
association, during the four (4) calendar weeks preceding the date of receipt of
the order to execute the sale.

          (b)  Stockholder may make unrestricted sales of Restricted Securities
pursuant to Rule l45(d)(2) if: (i) Stockholder has beneficially owned (within
the meaning of Rule 144(d) under the Securities Act) the Restricted Securities
for at least two (2) years after the Effective Time of the Merger; (ii)
Stockholder is not an affiliate of C-Cube; and (iii) C-Cube meets the public
information requirements of Rule 144(c).

          (c)  Stockholder may make unrestricted resales of Restricted
Securities pursuant to Rule 145(d)(3) if Stockholder has beneficially owned
(within the meaning of Rule 144(d) under the Securities Act) the Restricted

                                     FORM OF
                               AFFILIATE AGREEMENT


     This Affiliate Agreement (this "AGREEMENT") is made and entered into as 
of May 28, 1996, between C-Cube Microsystems Inc., a Delaware corporation 
("C-CUBE"), DiviCom Inc., a Delaware corporation ("DIVICOM"), and the 
undersigned affiliate ("STOCKHOLDER") of DiviCom.

                                    RECITALS

     A.   Concurrently with the execution of this Agreement, C-Cube and 
DiviCom have entered into an Agreement and Plan of Reorganization (the 
"REORGANIZATION AGREEMENT") which provides, among other things, for the 
merger (the "MERGER") of DiviCom with and into C-Cube Acquisition Corp.,  a 
Delaware corporation and a wholly-owned subsidiary of C-Cube ("MERGER SUB").  
Pursuant to the Merger, all outstanding capital stock of DiviCom will be 
canceled and extinguished and be converted automatically into the right to 
receive shares of C-Cube Common Stock pursuant to the Reorganization 
Agreement.

     B.   The Stockholder is the beneficial owner (as defined in Rule 13d-3 
under the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) 
of such number of shares of the outstanding capital stock of DiviCom as is 
indicated on the final page of this Agreement (the "SHARES").

     NOW THEREFORE, the parties agree as follows:

     1.   TAX TREATMENT:  RULE 145.  Stockholder understands and agrees that 
it is intended that the Merger will be treated as a "reorganization" for 
federal income tax purposes.  Stockholder further understands and agrees that 
Stockholder may be deemed to be an "affiliate" of DiviCom within the meaning 
of Rule 145 ("RULE 145") promulgated by the Securities and Exchange 
Commission (the "SEC") under the Securities Act of 1933, as amended (the 
"SECURITIES ACT"), although nothing contained herein should be construed as 
an admission of such fact.

     2.   RELIANCE UPON REPRESENTATIONS, WARRANTIES AND COVENANTS.  
Stockholder has been informed that the treatment of the Merger as a 
reorganization for federal income tax purposes requires that former 
stockholders of DiviCom maintain a meaningful continuing equity ownership 
interest in C-Cube after the Merger.  Stockholder understands that the 
representations, warranties and covenants of Stockholder set forth herein 
will be relied upon by C-Cube, DiviCom and their respective counsel.


                                      1


<PAGE>


     3.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF STOCKHOLDER.  
Stockholder represents, warrants and covenants as follows:

          (a)  Stockholder has full power and authority to execute this 
Agreement, to make the representations, warranties and covenants herein 
contained and to perform Stockholder's obligations hereunder.

          (b)  Set forth below the signatures below is the number of Shares 
owned by Stockholder, including all Shares as to which Stockholder has sole 
or shared voting or investment power and all rights, options and warrants to 
acquire DiviCom Capital Stock owned or held by Stockholder.

          (c)  The shares of C-Cube Common Stock issued to Stockholder as 
consideration in the Merger, and any C-Cube securities issued in exchange 
therefor, are hereinafter referred to as "Restricted Securities".  The 
Stockholder agrees, in addition to the limitations set forth in Section 3(d), 
that as to a portion of the Restricted Securities representing two-thirds of 
all Restricted Securities acquired by Stockholder less the amount contained 
in the Escrow Fund pursuant to the Reorganization Agreement in respect of 
Stockholder, Stockholder will not, for a period of 270 days from the date of 
this Agreement, sell, transfer, exchange, pledge (except in connection with a 
bona fide loan transaction), make charitable contributions in respect of, or 
otherwise dispose of such portion of the Restricted Securities (or any 
option, right or other interest with respect thereto).

          (d)  Notwithstanding the foregoing, Stockholder will not sell, 
transfer, exchange, pledge (except in connection with a bona fide loan 
transaction) or make charitable contributions in respect of, or otherwise 
dispose of any Restricted Securities (or any interest with respect thereto), 
unless: (i) such transaction is permitted pursuant to Rule 145(c) and 145(d) 
under the Securities Act; or (ii) counsel representing Stockholder, which 
counsel is reasonably satisfactory to C-Cube, shall have advised C-Cube in a 
written opinion letter reasonably satisfactory to C-Cube and C-Cube's legal 
counsel, and upon which C-Cube and its legal counsel may rely, that no 
registration under the Securities Act would be required in connection with 
such transaction; or (iii) a registration statement under the Securities Act 
covering the Restricted Securities (or interests with respect thereto) 
proposed to be disposed of, describing the manner and terms of the proposed 
disposition, and containing a current prospectus, shall have been filed with 
the SEC and made effective under the Securities Act; or (iv) an authorized 
representative of the SEC shall have rendered written advice to Stockholder 
(sought by Stockholder or counsel to Stockholder, with a copy thereof and all 
other related communications delivered to C-Cube) to the effect that the SEC 
would take no action, or that the staff of the SEC would not recommend that 
the SEC take any action, with respect to the proposed disposition if 
consummated.

          (e)  Stockholder has no present plan or intent to sell, transfer, 
exchange, pledge (other than in a preexisting bona fide margin account) or 
otherwise dispose of, including a distribution by a corporation to its 
stockholders (but excluding transactions among family members for tax or 
estate planning purposes or among corporate affiliates, and transfers 
occurring by operation of law or 


                                      2


<PAGE>


pursuant to court order) any of the shares of C-Cube Common Stock that 
Stockholder may acquire in connection with the Merger.  If any of 
Stockholder's representations in this subsection (e) cease to be true at any 
time prior to the Effective Time of the Merger, Stockholder will deliver to 
each of DiviCom and C-Cube, prior to the Effective Time of the Merger, a 
written statement to that effect, signed by Stockholder.

     4.   RULES 144 AND 145.  From and after the Effective Time of the Merger 
and for so long as is necessary in order to permit Stockholder to sell the 
C-Cube Common Stock held by Stockholder pursuant to Rule 145 and, to the 
extent applicable, Rule 144 under the Securities Act, C-Cube will use its 
best efforts to file on a timely basis all reports required to be filed by it 
pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, 
referred to in paragraph (c)(1) of Rule 144 under the Securities Act.

     5.   LIMITED RESALES.  Stockholder understands that, in addition to the 
restrictions imposed under Section 4, the provisions of Rule 145 limit 
Stockholder's public resales of Restricted Securities, in the manner set 
forth in subsections (a), (b) and (c) below:

          (a)  Unless and until the restriction "Cut-off" provisions of Rule 
145(d)(2) or Rule 145(d)(3) set forth below become available, public resales 
of Restricted Securities may only be made by Stockholder in compliance with 
the requirements of Rule 145(d)(1).  Rule 145(d)(1) permits such resales 
only:  (i) while C-Cube meets the public information requirements of Rule 
144(c); (ii) in broker's transactions or in transactions with a market maker; 
and (iii) where the aggregate number of Restricted Securities sold at any 
time together with all sales of restricted C-Cube Common Stock sold for 
Stockholder's account during the preceding three (3) month period does not 
exceed the greater of (A) one percent (1%) of the C-Cube Common Stock 
outstanding or (B) the average weekly volume of trading in C-Cube Common 
Stock on all national securities exchanges, or reported through the automated 
quotation system of a registered securities association, during the four (4) 
calendar weeks preceding the date of receipt of the order to execute the sale.

          (b)  Stockholder may make unrestricted sales of Restricted 
Securities pursuant to Rule 145(d)(2) if: (i) Stockholder has beneficially 
owned (within the meaning of Rule 144(d) under the Securities Act) the 
Restricted Securities for at least two (2) years after the Effective Time of 
the Merger; (ii) Stockholder is not an affiliate of C-Cube; and (iii)  C-Cube 
meets the public information requirements of Rule 144(c).

          (c)  Stockholder may make unrestricted resales of Restricted 
Securities pursuant to Rule 145(d)(3) if Stockholder has beneficially owned 
(within the meaning of Rule 144(d) under the Securities Act) the Restricted 
Securities for at least three (3) years and is not, and has not been for at 
least three (3) months, an affiliate of C-Cube.

          (d)  C-Cube acknowledges that the provisions of Section 5(c) will 
be satisfied as to any sale by the undersigned of the Restricted Securities 
pursuant to Rule 145(d), by a broker's letter and a letter from the 
undersigned with respect to that sale stating that each of the 
above-described 


                                      3


<PAGE>


requirements of Rule 145(d)(1) has been met or is inapplicable by virtue of 
Rule 145(d)(2) or Rule 145(d)(3); PROVIDED, HOWEVER, that C-Cube has no 
reasonable basis to believe that such sales were not made in compliance with 
such provisions of Rule 145(d).

     6.   LEGENDS.  Stockholder also understands and agrees that stop 
transfer instructions will be given to C-Cube's transfer agent with respect 
to certificates evidencing the Restricted Securities and that there will be 
placed on the certificate evidencing the Restricted Securities legends 
stating in substance:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED, SOLD,
          PLEDGED, EXCHANGED, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN
          ACCORDANCE WITH THE REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS
          AMENDED, AND THE OTHER CONDITIONS SPECIFIED IN THAT CERTAIN AFFILIATE

without limitation, a sale or transfer of C-Cube Common Stock permitted under 
Section 3.

further force and effect upon the termination of the Reorganization Agreement 
pursuant to Article VIII of the Reorganization Agreement.
